new CEO of the Company, or (ii) the employee is terminated by the Company
without cause prior to the date set forth in (i) above. The foregoing
modification as applied to the interim Co-CEOs extends their respective exercise
period to three years provided that they meet the conditions of clauses (i) or
(ii) above.

NOTE 3. ACQUISITIONS IN HONG KONG, CHINA AND TAIWAN

As previously reported in the Company's Form 10-Q for the period ending June 30,
1997, in an agreement effective as of June 1, 1997, the Company acquired New
System International Ltd., a Hong Kong corporation, for a net purchase price of
$1,564,000. During the third quarter of 1997, the Company completed the
documentation and formalities related to this stock purchase. New System
International Ltd. was previously the operating subsidiary of Papnet (Far East)
Ltd. a Hong Kong corporation ("PFEL"), a distributor of the Company's PAPNET(R)
Testing System in Hong Kong and China. New System International Ltd. also
provides clinical laboratory services through its Hong Kong-based Compuscreen
Medical Diagnostic Centre. Dr. Ng served as president of New System
International Ltd. prior to its acquisition and in the third quarter of 1997
entered into an employment agreement with the Company providing for his
continuation in such capacity.

In an agreement effective as of August 1, 1997, the Company acquired the assets
of the Taiwan PAPNET(R) distributor, Papnet Far East Ltd. (Taiwan) through the
Company's acquisition subsidiary, New System Ltd., for a purchase price of
$392,000. In a related transaction, the Company executed a license and
management services agreement with Papnet Far East Ltd. (Taiwan) for operation
of the Company's assets in Taiwan.

Related to each of the foregoing acquisitions, on September 30, 1997 PFEL
entered into an Amended and Restated Representation Agreement with the Company,
and a Sublicense Agreement with the Company's subsidiary, NSI Asia Pacific Ltd.,
pursuant to which the Company received $800,000 from PFEL for the right of PFEL
to receive a royalty of 3% to 4% based on sales in Hong Kong, China and Taiwan
over a fifteen year period. The Company expects that it will invest additional
cash in its Hong Kong, Taiwan and China businesses to fund operations and
expansion of their respective marketing and sales programs.

NOTE 4.        SUBSEQUENT EVENTS - CHANGES IN MANAGEMENT AND BOARD OF DIRECTORS

On November 5, 1997, the Company announced the appointment of Paul Sohmer, M.D.
as President and Chief Executive Officer of the Company, and the election by the
Board of C. Raymond Larkin, Jr. as the non-executive Chairman of the Board. From
June 30, 1997, when the Company announced that Mark R. Rutenberg submitted his
resignation as President and Chief Executive Officer of the Company, the Office
of the Chief Executive was filled jointly by Uzi Ish-Hurwitz and John B.
Henneman, III. Mr. Henneman will continue with the Company in his capacity as
Vice President of Corporate Development, Secretary and General Counsel, and Mr.
Ish-Hurwitz will continue with the Company as Executive Vice President, Chief of
Technical Operations and President, Neuromedical Systems Israel Ltd. In
addition, the Company increased the size of the Company's Board of Directors to
eight (8), and appointed Dr. Sohmer as a Class II member of the Board whose term
will end at the Annual Meeting of Stockholders in 2000. Mark Rutenberg, the
founder of the Company, was appointed non-executive Vice Chairman of the Board
and remains a Class III member of the Board whose term will end at the Annual
Meeting of Stockholders in 1998. Mr. Ish-Hurwitz continues as a Class I Director
of the Board whose term ends at the Annual Meeting of Stockholders in 1999.

The Company entered into an employment agreement with Dr. Sohmer, dated November
4, 1997 (the "Agreement"), which has a term of three years and is renewable
automatically for additional one year terms thereafter unless notice is given by
either party ninety days prior to the end of the then-current term. The material
provisions of the Agreement provide for Dr. Sohmer's employment, annual salary
and bonus eligibility. In addition, the Agreement and related option agreements
provide for a grant of options to Dr. Sohmer to acquire 750,000 shares of
Company Common Stock at an exercise price of $4.56 per share (the fair market
value of the Common Stock on the grant date), and options for an additional
250,000 shares of Common Stock at an exercise price of $10.00 per share. All of
such options vest and become exercisable at a rate of 25% of the total grant on
each anniversary of the grant date.

As previously reported in the Company's Form 10-Q for the period ending June 30,
1997, in connection with the resignation of Mark Rutenberg as President and CEO
of the Company, the Company entered into a revised and restated employment
agreement with Mr. Rutenberg on June 29, 1997 (the "Revised Agreement") which
will remain effective until November 19, 1998. The material provisions of the
Revised Agreement provide for Mr. Rutenberg's continuation of employment with
the Company and participation in the Company's executive benefit plans. In
addition, the Revised Agreement provides for a non-recourse loan to Mr.
Rutenberg from the Company in an amount of $600,000 which is secured by his
pledge of 100,000 shares of Company common stock. The loan is due on the earlier
of November 30, 1999 or the date which is ten days after termination of his
employment for any reason. The Revised Agreement may be terminated for "Cause"
(as defined in the Revised Agreement) or by either party to the Revised
Agreement upon

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL 
        CONDITION AND RESULTS OF OPERATIONS.

OVERVIEW

The Company's principal activities since its founding in 1988 have been research
and product and organizational development. The Company was established to
develop, manufacture and market systems for computer-assisted screening of
cervical Papanicolaou ("Pap") smears and other cytological specimens. The
Company's revenues are currently being derived from sales of PAPNET(R) testing
services and interest income.

The PAPNET(R) Testing System was approved by the United States Food and Drug
Administration (the "FDA") for commercial use in the United States on November
8, 1995. Prior to that time, the PAPNET(R) Testing System was permitted to be
utilized in the United States on an investigational basis only, and the Company
was permitted to derive revenue with respect thereto only to recover certain of
its costs. The Company, however, was previously selling PAPNET(R) testing
services for commercial use outside of the United States. The Company has
established three scanning facilities (the "Scanning Centers"), one each in the
United States, The Netherlands and Hong Kong. The Netherlands operation has
scanned slides primarily from customers in Europe while the Hong Kong operation
has scanned slides from Asia and Australia. During the third quarter of 1997,
the Company announced plans to sell PAPNET(R) scanners and related equipment to
laboratories in Europe, and in October 1997 the Company announced the signing of
its first European sales contract. The Company expects to deliver the first
PAPNET-on-Cyte(TM) system in the fourth quarter of 1997. Although the Company
has no active plans to sell scanners in the United States and international
markets other than Europe, it may do so if customers express a strong interest
in the PAPNET-on-Cyte(TM) system and acceptable economic terms can be reached
with the customer. See Note 5 of Notes to Consolidated Financial Statements for
the year ended December 31, 1996 for information regarding the Company's
revenues, net loss and identifiable assets by geographic area.

The Company has incurred net losses since inception through September 30, 1997
of $122,246,000 and has to date generated only limited commercial revenues.
Since the approval of the PAPNET(R) Testing System by the FDA, the Company has
been increasing the scale of its operations to commercial levels in the United
States. Management believes that its existing cash resources will be sufficient
to fund the increase in the scale of the Company's operations and to meet its
cash requirements through 1998, although there can be no assurance in this
regard. The Company's past results of operations reflect its developmental or
early commercial stage and are not necessarily indicative of the results from
operations that may be expected as the scale of its operations increases.

                                      -10-
<PAGE>
 
RESULTS OF OPERATIONS

The Company's results of operations have fluctuated significantly from year to
year and quarter to quarter, principally due to variations in the level of
expenditures relating to its clinical trials, research projects, marketing and
sales programs and international expansion. The Company's results of operations
are expected to continue to fluctuate significantly and may continue to result
in substantial losses.

From inception through September 30, 1997, the Company has experienced negative
gross margins due to the significant under-utilization of its scanning and
manufacturing operations which occurred as a result of the plan to establish
these capabilities prior to FDA approval and then-expected market demand.
Improvement in the Company's future gross margins will be dependent upon the
level of commercial acceptance of the PAPNET(R) Testing System.

The Company's costs and expenses have increased substantially during 1997,
compared to 1996, as the Company continues to expand its commercial operations,
including its marketing, sales, manufacturing, slide processing, research and
administrative activities, to meet the anticipated increase in market demand for
PAPNET(R) testing, expand its clinical claims and develop enhancements to the
PAPNET(R) Testing System and to fund the acquisition and expected losses of the
Company's new operations in Hong Kong, China and Taiwan acquired in June and
August of 1997. General and administrative costs have also increased during 1997
due principally to higher legal fees (primarily related to Company litigation),
and costs associated with the severance of the former CEO and recruitment of his
replacement. The Company anticipates that aggregate costs and expenses will
increase only modestly or decline in 1998 over 1997 because of the Company's
decision to reduce direct-to-consumer advertising and agency related costs, and
to focus sales and marketing efforts on the laboratory customer and opinion
leading clinicians. In addition, the Company believes that the decision to sell
scanners to European laboratories will create a more cost effective selling
process in that market and reduce related slide processing costs. Nevertheless,
total costs and expenses may not decline significantly in 1998 because of
expected increases in manufacturing and slide processing costs, higher clinical
costs as the Company initiates clinical studies for a primary screening
indication in the United States, increased costs associated with the Company's
operation of its Hong Kong, China and Taiwan acquisitions for a full year in
1998 versus a partial year in 1997, uncertainty over the level of costs
associated with ongoing litigation, and higher royalty payments that will
increase proportionate to increases in the Company's revenues in the sales
territories of the Company's territorial licensees ("Licensees").

During the third quarter, the Company focused its efforts on developing more
effective relationships with laboratories in order to be more responsive to the
concerns and needs of the medical marketplace, and to address certain obstacles
which the Company has perceived as hindering its marketing programs. The Company
believes that several programs initiated during the third quarter will add value
in the pathology laboratories, 

                                      -11-
<PAGE>
 
both medically and economically, and that laboratories are becoming more
supportive of PAPNET(R) testing. The Company also continued its efforts to build
support among opinion-leading cytopathologists and cytotechnologists. Several
programs announced during the third quarter contributed toward that goal.

First, the Company assembled a distinguished group of physicians into a
pathology advisory board (PAB). The PAB is comprised of independent physicians
who will help direct the Company's efforts in the development of services and
programs that can help laboratory professionals improve patient care. The PAB
held its first meeting in September and will continue to meet periodically
throughout the coming year. The Company expects that the PAB will add value to
the laboratory and to NSI.

Second, the Company launched the PAPNET(R) Access Program, a partnership with
ten academic medical centers to provide free PAPNET(R) testing to indigent
women, and to gather data on the benefits that PAPNET(R) testing can confer to
infrequently screened populations.

Finally, in October the Company announced the publication of its Food and Drug
Administration (FDA) clinical trial in the peer-review journal Human Pathology,
showing PAPNET(R) testing can help laboratories detect cervical cancer more
efficiently and earlier. This publication now brings the total number of
peer-reviewed manuscripts on PAPNET(R) testing in gynecologic cytology to
thirty-six (36) and contributes to the large body of data that makes PAPNET(R)
testing one of the most widely studied and thoroughly reviewed technologies in
cervical cancer screening.

During the third quarter, the Company also initiated new programs to help the
Company communicate more effectively with pathologists at customer labs. NSI
sponsored workshops for pathologists to discuss how PAPNET(R) testing can help
laboratory professionals improve patient care. These programs were designed to
provide pathologists with a better understanding of the clinical and economic
value of integrating PAPNET(R) testing into their laboratories.

The Company also focused its technical efforts for the benefit of the pathology
laboratory customer. The Company has implemented its Laboratory Support Group
(LSG). The LSG has hired cytotechnologists with extensive experience in both
hands-on cytology and in the supervision of cytotechnology teams.

During the month of October, the Company signed a contract with Mercy Medical
Center of Canton, Ohio to rescreen 100% of its Pap smear slides using the
PAPNET(R) Testing System. The Company expects to begin generating revenue from
this contract during the fourth quarter of 1997.

The Company made significant progress in its commitment to seek approval of the
PAPNET(R) Testing System as a primary screening device in the United States, and
is working with the FDA to establish the trial protocol. The Company expects to
complete 

                                      -12-
<PAGE>
 
site selection and training in the fourth quarter of 1997, and anticipates that
it will begin screening trial smears during the first quarter of 1998.

Interest expense is expected to increase in the future as the Company borrows to
fund expansion of its manufacturing, slide processing and marketing
capabilities, including the installation of PAPNET(R) Scanning Stations at the
Company's Scanning Centers. It is expected that this increase will continue to
be substantially offset during 1997 by interest income from the investment of
the Company's cash. The Company's interest income has declined in 1997, compared
to 1996, because of the significant use of cash in 1996 and 1997.

The impact of inflation and changing prices on the Company's revenues and costs
has not been significant.

RESULTS FOR THE THIRD QUARTER ENDING SEPTEMBER 30, 1997

Revenues for the third quarter of 1997 were $2,526,000, an increase of 96% from
$1,286,000 during the third quarter of 1996. Of such revenues, $2,387,000
represented per slide charges for the screening of Pap smears, and the balance
of such revenues represented the sale or rental payments for PAPNET(R) Review
Stations. The revenue increase over the third quarter of 1996 was due to a
significant increase in unit volume, higher average unit pricing, including the
pricing impact of the acquisition of the Company's new operations in Hong Kong,
China and Taiwan, and additional revenues from the sale or rental of Review
Stations.

Unit volume during the third quarter of 1997, compared to the third quarter of
1996, increased in both the United States and in international markets and
accounted for approximately 40% of the revenue increase between the periods. For
United States operations (which include Canada and South America), unit volume
increased 93% over the third quarter of 1996. In International markets, unit
volume increased 8% over the third quarter of 1996. Average unit pricing in the
third quarter of 1997 increased by approximately 38% over the third quarter of
1996 due to a higher proportion of slide volume being generated in the United
States and the acquisition of the Company's new operations in Hong Kong, China
and Taiwan. This increase in average unit pricing accounted for approximately
53% of the revenue increase. Finally, the impact of higher revenue from the sale
or rental of review stations accounted for the remaining 7% of the worldwide
revenue increase.

Total costs and expenses for the quarter ended September 30, 1997 were
$12,124,000, an increase of $273,000 over the third quarter of 1996. This
increase was due primarily to an increase in cost of sales and general and
administrative expenses, partially offset by lower sales and marketing expenses.

Sales and marketing expenses declined to $3,962,000 in the third quarter of 1997
from $6,262,000 in the third quarter of 1996, a decrease of $2,300,000. The
decline in sales 

                                      -13-
<PAGE>
 
and marketing expenses was due primarily to lower costs for advertising and
agency fees in the United States, consistent with the Company's efforts to
become a laboratory-focused marketing organization. This decline was partially
offset by higher costs for sales and marketing programs in international
markets.

The Company's cost of sales increased to $3,138,000 in the third quarter of
1997, compared to $2,085,000 during the third quarter of 1996, an increase of
$1,053,000. The increase in cost of sales was due primarily to increased royalty
expenses as a result of increases in the Company's revenues in the sales
territories of the Licensees during 1997, the addition of the operating costs
for the laboratory business of New System International Ltd., the Hong Kong
company which was acquired by the Company in June 1997, and the expansion of
slide processing and manufacturing capacity. Slide processing costs increased in
1997, compared to the third quarter of 1996, due to the establishment of the
Company's new 26,500 square foot scanning center in New Jersey in October, 1996
and the additional cost of increased depreciation and other costs at the
Company's three slide processing facilities. Manufacturing costs increased due
to the physical expansion of the Company's manufacturing facility in late 1996
and expansion of manufacturing capacity and related overhead.

The Company's research and development expenses increased to $2,207,000 in the
third quarter 1997, from $1,945,000 in the third quarter of 1996. This increase
was due primarily to the expansion of the product development and medical
organizations of the Company to support expanded clinical claims and indications
and future enhancements of the PAPNET(R) Testing System.

General and administrative expenses were $2,817,000 during the third quarter of
1997 compared to $1,559,000 during the third quarter of 1996. This increase was
due primarily to higher legal expenses (primarily for litigation), increased
recruiting costs associated with the search for a new CEO and severance related
costs for the former CEO.

Interest income for the third quarter ended September 30, 1997 was $816,000
compared to $1,236,000 during the third quarter of 1996. This decrease was due
primarily to the lower level of cash, cash equivalents and short term
investments available to the Company during the third quarter of 1997 as a
result of the Company's continuing losses in 1996 and the first nine months of
1997.

Interest expense during the third quarter of 1997 was $397,000 compared to
$305,000 during the third quarter of 1996. This increase was due to higher
average levels of debt and capital lease obligations, which the Company entered
into in late 1996 and 1997, incurred to finance capital equipment additions,
primarily related to the Company's PAPNET(R) Scanning Stations. The Company
anticipates higher levels of interest expense during the remainder of 1997 and
in 1998 as a result of the increased levels of debt and capital lease
obligations.

                                      -14-
<PAGE>
 
The Company incurred a net loss during the third quarter of 1997 of $9,244,000,
or $0.30 per share, compared to a net loss of $9,588,000, or $0.33 per share
during the third quarter of 1996. The lower net loss during the third quarter of
1997 was due primarily to the factors discussed above.

RESULTS FOR THE NINE MONTH PERIOD ENDING SEPTEMBER 30, 1997

Revenues for the nine month period ending September 30, 1997 were $6,407,000, an
increase of 117% from $2,954,000 during the same period of 1996. This revenue
increase was due to a significant increase in unit volume, higher average unit
pricing, including the pricing impact of the acquisition of new operations in
Hong Kong, China and Taiwan, and additional revenues from the sale or rental of
Review Stations.

Unit volume during the first nine months of 1997, compared to the same period of
1996, increased in all of the Company's major markets including the United
States, Asia, Australia and Europe and accounted for approximately 49% of the
revenue increase. For United States operations (includes Canada and South
America), unit volume increased 123% over the same period of 1996. In
international markets, unit volume increased 27% over 1996. Worldwide average
unit pricing during the first nine months of 1997 increased by approximately 36%
over the same period of 1996 and accounted for approximately 47% of the revenue
increase due primarily to a higher proportion of slide volume being generated in
the United States and the acquisition of the laboratory and marketing operations
in Hong Kong, China and Taiwan. Finally, increased revenue from the sale or
rental of review stations accounted for the remaining 4% of the worldwide
revenue increase.

Total costs and expenses for the period ended September 30, 1997 were
$35,674,000, an increase of $6,191,000 over the same period of 1996. This
increase was due primarily to an increase in general and administrative expenses
(principally related to Company litigation, severance costs for the former CEO
and recruiting fees for his replacement), research and development expenses, and
cost of sales (primarily associated with increased royalty expenses as a result
of increased sales in the territories of the Licensees, and the expansion of
slide processing and manufacturing capacity).

Sales and marketing expenses increased to $14,273,000 during the first nine
months of 1997 from $13,635,000 during the same period of 1996, an increase of
$638,000. The increase in sales and marketing expenses was due primarily to
costs associated with marketing the PAPNET(R) Testing System in the United
States and Europe, including salaries for additional personnel and advertising
and promotion costs of the PAPNET(R) Testing System, and to the acquisition of
new operations in Hong Kong, China and Taiwan in June and August of 1997.

The Company's cost of sales increased to $8,390,000 in 1997, compared to
$5,709,000 during the same period of 1996, an increase of $2,681,000. As was the
case for the quarter, this increase was primarily associated with increased
royalty expenses as a result 

                                      -15-
<PAGE>
 
of increases in the Company's revenues in the sales territories of the Licensees
during 1997, the acquisition of the laboratory business of New System
International Ltd. in June 1997 and the expansion of the Company's slide
processing and manufacturing capacity.

The Company's research and development expenses increased to $6,196,000 in 1997,
from $5,024,000 during the same period of 1996. This increase was due primarily
to the expansion of the product development and medical organizations of the
Company to support expanded clinical claims and indications, and future
enhancements of the PAPNET(R) Testing System.

The Company's general and administrative expenses increased to $6,815,000 during
the first nine months of 1997, compared to $5,115,000 for the same period of
1996. This increase was due primarily to higher legal expenses, primarily for
litigation, increased recruiting costs associated with the search for a new CEO
and severance related costs for the former CEO.

Interest income for the nine month period ended September 30, 1997 was
$2,812,000 compared to $4,044,000 during the same period of 1996. This decrease
was due primarily to the lower level of cash, cash equivalents and short term
investments available to the Company during 1997 as a result of the Company's
continuing losses in 1996 and the first nine months of 1997.

Interest expense during the first nine months of 1997 was $1,213,000 compared to
$789,000 during the same period 1996. As was the case for the third quarter of
1997, this increase was due to higher average levels of debt and capital lease
obligations incurred to finance capital equipment additions.

The Company incurred a net loss during the first nine months of 1997 of
$27,738,000, or $0.90 per share, compared to a net loss of $23,813,000, or $0.82
per share during the same period of 1996. The increased net loss was due to the
factors discussed above.

LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its operations since its inception primarily by the
issuance of equity securities, sales of PAPNET(R) Testing System services, funds
received for the territorial license agreements (prior to 1992), interest earned
on cash, cash equivalents and short-term investments and proceeds from notes,
bank loans and equipment leasing arrangements. In addition, the Company has
announced plans to sell PAPNET(R) equipment to laboratories in Europe and has
announced that the first contract with a European customer has been signed. The
Company expects to generate revenues from this contract in the fourth quarter of
1997.

The Company's combined cash and cash equivalents, and short term investments
totaled $52,824,000 at September 30, 1997, a decrease of $30,567,000 from
December 31, 1996. During the first nine months of 1997, the Company used
$25,858,000 for operating 

                                      -16-
<PAGE>
 
activities, $35,812,000 for investing activities, including the purchase of
$30,182,000 of short term investments, while generating $807,000 from financing
activities. In addition, the effect of exchange rate changes on cash was
$114,000, which accounted for the remaining change to the Company's cash
balance.

The primary uses of cash and cash equivalents during the first nine months of
1997 were $27,738,000 (inclusive of $3,827,000 of non-cash items) to finance the
Company's net loss, $30,182,000 to purchase short term investments, $3,874,000
to purchase capital equipment, primarily for the manufacture of PAPNET(R)
Scanning Stations and related equipment to support the expansion of the
Company's scanning capacity, a net amount of $1,156,000 to acquire the Company's
new operations in Hong Kong, China and Taiwan (See Note 3 to Condensed
Consolidated Financial Statements set forth above), a $600,000 non-recourse loan
to the Company's former CEO in connection with his severance agreement (see Note
4 to the Notes to Condensed Consolidated Financial Statements set forth above),
$3,012,000 to repay notes, bank loans and capital lease obligations, and
$1,947,000 for changes in operating assets and liabilities.

The sources of cash and cash equivalents during the first nine months of 1997
were proceeds of $1,690,000 from notes and bank loans, proceeds of $1,669,000
from capital lease financing transactions (sale/leaseback), a reduction in
restricted cash of $181,000 and proceeds of $279,000 from the issuance of common
stock, associated with the exercise of stock options.

The Company anticipates that its use of cash will be substantial for the
foreseeable future. In particular, the Company anticipates that expenditures
during the balance of 1997 and in 1998 will continue to be significant due to
the cost of marketing the PAPNET(R) Testing System in the United States, the
cost of marketing and sales programs in overseas markets, research and
development programs for additional clinical indications and claims, and the
cost of on-going litigation. The Company anticipates that, during 1997, it will
invest approximately $4.0 million for working capital purposes and approximately
$7.0 million for capital expenditures, leasehold improvements and the
acquisition costs of the Company's new operations in Hong Kong, China and
Taiwan. Although funding for capital expenditures is expected to be available
out of the Company's cash resources, management believes that it may be
desirable for the Company to finance certain of such capital expenditures
through additional debt or capital lease obligations.

During 1996 and 1997, the Company entered into loan and equipment lease
agreements with two equipment financing companies to provide the Company with
approximately $11.0 million of lines of credit to finance certain of the
Company's equipment purchases. During 1996 and 1997, the Company borrowed
approximately $8.0 million under the agreements. The Company is required to
maintain certain financial covenants throughout the duration of both the loan
and lease agreements. The agreements stipulate that additional funding can be
denied in the event of a material adverse change in the financial condition,
operation or prospects of the Company. The loan and lease commitments expire on
December 31, 1997. There can be no assurance, however, that the remaining credit
line balance of $3.0 million of these loan and equipment lease agreements, or
any 

                                      -17-
<PAGE>
 
other financings, will ultimately be obtained by the Company or, if 
obtained, that the terms thereof will not change or will be reasonable.

The Company anticipates that its current cash and cash equivalents will be
sufficient to enable the Company to meet its future operating requirements
through 1998. The Company does not expect to generate a positive internal cash
flow in the foreseeable future due to continued capital expenditures, working
capital requirements, repayment of debt and capital lease obligations, and
ongoing losses during the next year, including the expected cost of continued
commercialization of the PAPNET(R) Testing System. The Company may need to
arrange additional equity or debt financing for the future operation of its
business. There can be no assurance that such financing can be obtained or, if
it is obtained, that the terms thereof will be reasonable. The Company plans to
invest excess funds in short-term instruments, including money market funds.

On November 5, 1997, the Company announced the appointment of Paul Sohmer, M.D.
as President and Chief Executive Officer of the Company, and the election by the
Board of C. Raymond Larkin, Jr. as the non-executive Chairman of the Board. In
addition, the Company increased the size of the Company's Board to eight (8),
and appointed Dr. Sohmer as a member of the Board. Mark Rutenberg, the founder
of the Company, was appointed non-executive Vice Chairman of the Board. See the
Notes to the Condensed Consolidated Financial Statements Note 4, set forth
above, which describes in detail the foregoing developments.

As previously reported in the Company's Form 10-Q for the period ending June 30,
1997, in an agreement effective as of June 1, 1997, the Company acquired New
System International Ltd., a Hong Kong corporation, for a net purchase price of
$1,564,000 and, in an agreement effective as of August 1, 1997, the Company
acquired the assets of the Taiwan PAPNET(R) distributor, Papnet Far East Ltd.
(Taiwan) through the Company's acquisition subsidiary, New System Ltd., for a
purchase price of $392,000. In addition, the Company and its subsidiary, NSI
Asia Pacific Ltd., entered into agreements with PFEL pursuant to which the
Company received $800,000 for the right of PFEL to receive a royalty of 3% to 4%
based on sales in Hong Kong, China and Taiwan. See the Notes to the Condensed
Consolidated Financial Statements Note 3, set forth above, which describes in
detail the foregoing and related transactions.

To date, the Company has not implemented a program to hedge its foreign currency
risk, but may do so in the future.

As previously reported in the Company's Forms 10-Q for the periods ended March
31, 1997 and June 30, 1997, each respectively filed with the Securities and
Exchange Commission (the "Commission"), the Company is a defendant in a civil
lawsuit brought by Herbst et al., a patent infringement lawsuit filed by
NeoPath, Inc. ("NeoPath"), and a civil lawsuit by Cytyc Corporation. The Company
is the plaintiff in a lawsuit against NeoPath for patent infringement and
additional claims related to unfair business practices, and NeoPath has filed
counter-claims against the Company in such lawsuit 

                                      -18-
<PAGE>
 
seeking damages and injunctive relief for false advertising and unfair
competition. Each of the foregoing lawsuits have been disclosed in the Company's
previous filings with the Commission and no material developments have occurred
since the most recent such filing. The Company believes that an adverse judgment
in any or all of these cases would not have a material adverse effect on the
Company's operations, financial position or cash flows, but there can be no
assurance in this regard.

                      NONQUALIFIED STOCK OPTION AGREEMENT

                              REPLACEMENT OPTIONS

          THIS AGREEMENT, effective as of the 28th day of July, 1997 (the "Grant
Date"), between Neuromedical Systems, Inc., a Delaware corporation (the
"Company"), and [name of employee] (the "Optionee").

          WHEREAS, the Company has adopted the Neuromedical Systems, Inc. 1993
Stock Option Plan, as amended and restated on October 25, 1995 (the "Plan") in
order to provide additional incentive to selected directors, officers, employees
and consultants of the Company and its Subsidiaries; and

          WHEREAS, the Company previously granted to the Optionee, effective as
of [prior grant date] certain option rights to purchase all or any part of an
aggregate of [amount of prior grant] whole Shares, subject to the terms and
conditions of an agreement between Optionee and the Company dated as of even
date therewith (the "Old Options" and such agreement governing the terms of
grant and exercise thereof, the "Old Option Agreement").

          WHEREAS, as of July 28, 1997 and as authorized by the provisions of
Article 3 of the Plan, the Board of Directors of the Company duly adopted a
resolution authorizing the issuance of replacement options (the "Replacement
Options") to acquire shares of Company common stock, $.0001 par value per share
("Common Stock"), in substitution of outstanding stock options granted on or
after October 1, 1996, as and when such options are surrendered by the holders
thereof, among which are the Old Options; and

          WHEREAS, the Optionee desires to surrender Old Options in exchange for
the Replacement Options and the Company and the Optionee hereby wish to
memorialize the terms and conditions applicable to the Replacement Options;

          NOW, THEREFORE, the parties hereto agree as follows:

Optionee of all right, title and interest in Optionee's Old Options and (b)
termination of any and all rights, obligations and duties of each of the parties
hereto under the terms of Optionee's Old
<PAGE>
 
Option Agreement and any and all ancillary representations or agreements by the
Company with respect thereto, the Company hereby grants to the Optionee the
right and option (the "Option") to purchase all or any part of an aggregate of
[amount of replacement options] whole Shares subject to, and in accordance with,
the terms and conditions set forth in this Agreement.  Each of the parties
hereto agree that foregoing conditions (a) and (b) of this paragraph 1.1 shall
each be duly performed, acknowledged and definitively evidenced by the sole act
of execution of this Agreement.

               1.2  The Option is not intended to qualify as an Incentive Stock
Option within the meaning of Section 422 of the Code.

               1.3  This Agreement shall be construed in accordance and
consistent with, and subject to, the terms of the Plan (the provisions of which
are incorporated herein by reference); and, except as otherwise expressly set
forth herein, the capitalized terms used in this Agreement shall have the same
definitions as set forth in the Plan.

          2.   Purchase Price.
               -------------- 

          The price at which the Optionee shall be entitled to purchase Shares
upon the exercise of the Option shall be $4.00 per Share.

          3.   Duration of Option.
               ------------------ 

          Subject to the terms and conditions of this Agreement, the Option
shall be exercisable to the extent and in the manner provided herein for a
period of ten (10) years from the Grant Date (the "Exercise Term"); provided,
                                                                    -------- 
however, that the Option may be earlier terminated as provided in Section 6
- -------                                                                    
hereof.

          4.   Exercisability of Option.
               ------------------------ 

          Subject to the terms and conditions of this Agreement, the Option
shall be exercisable as follows:

          (a) The Option shall become vested and exercisable with respect to 25%
of the aggregate number of Shares covered by the Option as of each of the first,
second, third and fourth anniversaries of the Grant Date, provided,
                                                          -------- 
however, that in the event that the Optionee is terminated by the Company
"without cause" (as defined in the Plan) prior to July 28, 1998, 25% of
Optionee's Option will vest and become exercisable as of such termination date.

          (b) Any fractional number of shares resulting from the application of
the percentages set forth above in this Section 4 shall be rounded to the next
higher whole number of Shares.

          5.   Manner of Exercise and Payment.
               ------------------------------ 

               5.1  Subject to the terms and conditions of this Agreement and
the Plan, the Option may be exercised by delivery of written notice to the
Company, at its principal executive office.  Such notice shall state that the
Optionee is electing to exercise the Option and the number of Shares in respect
of which the Option is being exercised and shall be signed by the person or
persons exercising the Option.  If requested by the Committee (as defined in the
Plan), such person or persons shall (i) deliver this Agreement to the Secretary
of the Company who shall endorse thereon a notation of such exercise and (ii)
provide satisfactory proof as to the right of such person or persons to exercise
the Option.

               5.2  The notice of exercise described in Section 5.1 shall be
accompanied by (x) either (i) payment of the full purchase price for the Shares
in respect of which the Option is being exercised, in cash, by check or, at the
sole discretion of the Committee, by transferring Shares to the Company having a
Fair Market Value on the day preceding the date of exercise equal to the cash
amount for which such Shares are substituted or (ii) subject to the consent of
the Committee, instructions from the Optionee to the Company directing the
Company to deliver a specified number of Shares directly to a designated broker
or dealer pursuant to a cashless exercise election which is made in accordance
with such requirements and procedures as are acceptable to the Committee in its
sole discretion and (y) full payment of all applicable Withholding Taxes (as
defined in Section 11) pursuant to Section 11 hereof

                5.3  Upon receipt of the notice of exercise and any payment or
other documentation as may be necessary pursuant to Section 5.2 relating to the
Shares in respect of which the Option is being exercised, the Company shall,
subject to the Plan and this Agreement, take such action as may be necessary to
effect the transfer to the Optionee of the number of Shares as to which such
exercise was effective.

                5.4  The Optionee shall not be deemed to be the holder of, or to
have any of the rights of a holder with respect to any Shares subject to the
Option until (i) the Option shall have been exercised pursuant to the terms of
this Agreement and the Optionee shall have paid the full purchase price for the
number of Shares in respect of which the Option was exercised, (ii) the Company
shall have issued and delivered the Shares to the Optionee, and (iii) the
Optionee's name shall have been entered as a stockholder of record on the books
of the Company, whereupon the Optionee shall have full voting and other
ownership rights with respect to such Shares.

          6.   Termination of Employment.
               ------------------------- 

               6.1  Death or Disability.  In the event the employment of the
                    -------------------                                     
Optionee is terminated as a result of Disability or death, the Optionee may at
any time within one (1) year after such termination of employment, exercise the
Option to the extent, but only to the extent, that the Option or portion thereof
was exercisable on the date of such termination of employment, after which time
the Option shall terminate in full.  In the event of the Optionee's

                                      -3-
<PAGE>
 
death, the Option shall be exercisable, to the extent provided in the Plan and
this Agreement, by the legatee or legatees under the Optionee's will, or by the
Optionee's personal representatives or distributees and such person or persons
shall be substituted for the Optionee each time the Optionee is referred to
herein.

               6.2  Cause.  In the event the employment of the Optionee is
                    -----                                                 
terminated for Cause, the Option shall terminate on the date of the Optionee's
termination of employment whether or not exercisable.

               6.3  Other Termination of Employment.  If the employment of the
                    -------------------------------                           
Optionee is terminated for any reason other than Disability, death or Cause
(including the Optionee's ceasing to be employed by a Subsidiary or division of
the Company or any Subsidiary as a result of the sale of such Subsidiary or
division or an interest in such Subsidiary or division), the Optionee may at any
time within three (3) months after such termination of employment, exercise the
Option to the extent, but only to the extent, that the Option or portion thereof
was exercisable on the date of the termination of employment, after which time
the Option shall terminate in full.

          7.   Nontransferability.
               ------------------ 

          The Option shall not be transferable other than by will or by the laws
of descent and distribution or pursuant to a qualified domestic relations order
as defined in the Code or by such other means explicitly permitted pursuant to
Rule 16b-3 under the Exchange Act.  During the lifetime of the Optionee, the
Option shall be exercisable only by the Optionee, except in the case of an
Option transferred pursuant to a qualified domestic relations order.

          8.   No Right to Continued Employment.
               -------------------------------- 

          Nothing in this Agreement or the Plan shall be interpreted or
construed to confer upon the Optionee any right with respect to continuance of
employment by the Company or any Subsidiary, nor shall this Agreement or the
Plan interfere in any way with the right of the Company or any Subsidiary to
terminate the Optionee's employment at any time.

          9.   Adjustments.
               ----------- 

          In the event of a Change in Capitalization, the Committee may make
appropriate adjustments to the number and class of Shares or other stock or
securities subject to the Option and the purchase price for such Shares or other
stock or securities.  The Committee's adjustment shall be made in accordance
with the provisions of Section 6 of the Plan and shall be final and binding for
all purposes of the Plan and this Agreement.

          10.  Effect of a Liquidation, Merger or Consolidation.
               ------------------------------------------------ 

          Upon the effective date of (i) the liquidation or dissolution of the
Company or (ii) a merger or consolidation of the Company (a "Transaction"), the
Option shall continue in

                                      -4-
<PAGE>
 
effect in accordance with its terms and the Optionee shall be entitled to
receive in respect of each Share subject to the Option, upon exercise of the
Option, the same number and kind of stock, securities, cash, property or other
consideration that each holder of a Share was entitled to receive in the
Transaction in respect of a Share.

          11.  Withholding of Taxes.
               -------------------- 

          The Company shall have the right to deduct from any distribution of
cash to the Optionee an amount equal to the federal, state and local income
taxes and other amounts as may be required by law to be withheld (the
"Withholding Taxes") with respect to the Option.  If the Optionee is entitled to
receive Shares upon exercise of the Option, the Optionee shall pay the
Withholding Taxes to the Company in cash prior to the issuance of such Shares.
In satisfaction of the Withholding Taxes, the Optionee may make a written
election (the "Tax Election"), which may be accepted or rejected in the
discretion of the Committee, to have withheld a portion of the Shares issuable
to him or her upon exercise of the Option, having an aggregate Fair Market
Value, on the date preceding the date of such issuance, equal to the Withholding
Taxes, provided that if the Optionee may be subject to liability under Section
16(b) of the Exchange Act either (i) (A) the Tax Election is made at least six
(6) months prior to the date the Option is exercised and (B) the Tax Election is
irrevocable with respect to the exercise of all Options which are exercised
prior to the expiration of six (6) months following a revocation of the Tax
Election or (ii) (A) the Optionee makes the Tax Election at least six (6) months
after the Grant Date, (B) the Option is exercised during the ten-day period
beginning on the third business day and ending on the twelfth business day
following the release for publication of the Company's quarterly or annual
statement of sales and earnings (a "Window Period"), and (C) the Tax Election is
made during the Window Period in which the Option is exercised or prior to such
Window Period and subsequent to the immediately preceding Window Period.

          12.  Optionee Bound by the Plan.
               -------------------------- 

          The Optionee hereby acknowledges receipt of a copy of the Plan and
agrees to be bound by all the terms and provisions thereof.

          13.  Modification of Agreement.

          This Agreement may be modified, amended, suspended or terminated, and
any terms or conditions may be waived, but only by a written instrument executed
by the parties hereto, provided, however, that the Company may unilaterally

rights under this Agreement or the Plan, and (ii) reasonable notice of any such
unilateral amendment is provided to Optionee.

          14.  Severability.
               ------------ 

          Should any provision of this Agreement be held by a court of competent
jurisdiction to be unenforceable or invalid for any reason, the remaining
provisions of this Agreement shall not be affected by such holding and shall
continue in full force in accordance with their terms.

          15.  Governing Law.
               ------------- 

          The validity, interpretation, construction and performance of this
Agreement shall be governed by the laws of the State of Delaware without giving
effect to the conflicts of laws principles thereof.

          16.  Successors in Interest.
               ---------------------- 

          This Agreement shall inure to the benefit of and be binding upon any
successor to the Company.  This Agreement shall inure to the benefit of the
Optionee's legal representatives.  All obligations imposed upon the Optionee and

                                    --------
                              EMPLOYMENT AGREEMENT
                              --------------------

     AGREEMENT, effective as of the 1st day of July, 1997, by and between
NEUROMEDICAL SYSTEMS, INC., a Delaware corporation with principal executive
offices at Two Executive Boulevard, Suffern, New York 10901-4114 ("NSI"), and
[Employee], (the "Employee").

                             W I T N E S S E T H :
     WHEREAS, the Employee is currently employed by NSI as [executive position];
and

          WHEREAS, NSI is desirous of continuing to employ the Employee of NSI
in such capacity, and the Employee is desirous of continuing to serve NSI in
such capacity, all upon the terms and subject to the conditions hereinafter
provided.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereto, intending to be legally bound, agree as
follows:

     1.  Employment.
         ---------- 
     NSI agrees to employ the Employee, and the Employee agrees to be employed
by NSI, upon the terms and subject to the conditions of this Agreement.

     2.  Term.
         ---- 
     The employment of the Employee by NSI as provided in Section 1 will be for
the period commencing on the date hereof (the "Commencement Date") and ending on
the third anniversary of the Commencement Date (the "Term"); provided, however,
on the third anniversary of the Commencement Date and on each anniversary
thereafter, the Term shall be
<PAGE>
 
automatically extended for an additional period of one (1) year, unless either
party gives written notice to the other at least ninety (90) days' prior thereto
that the Term of this Agreement shall not be so extended; provided, further,
however, that the Term may be earlier terminated as hereinafter provided.

     3.  Duties; Best Efforts; Indemnification.
         ------------------------------------- 

     The Employee shall serve as [executive position] of NSI, or such other
senior management level position(s) as the Board of Directors of NSI (the
"Board") may from time to time and in its reasonable discretion appoint the
Employee, and shall perform and discharge well and faithfully the duties which
may from time to time be prescribed by the President and Chief Executive Officer
of NSI.  The Employee shall devote all of his business time, attention and
energies to the business and affairs of NSI, shall use his best efforts to
advance the best interests of NSI and shall not during the Term be actively
engaged in any other business activity, whether or not such business activity is
pursued for gain, profit or other pecuniary advantage.

     Subject to the provisions of NSI's Certificate of Incorporation and Bylaws,
each as amended from time to time, NSI shall indemnify the Employee to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as amended from time to time, for all amounts (including without
limitation, judgments, fines, settlement payments, expenses and attorney's fees)
incurred or paid by the Employee in connection with any action, suit,
investigation or proceeding arising out of or relating to the performance by the
Employee of services for, or the acting by the Employee as an officer or
employee of, NSI, or any other person or enterprise at NSI's request; provided,
however, that NSI shall not be required to indemnify the Employee against any
liability resulting from conduct which is willful, intentional or grossly
negligent.  NSI shall use its best efforts to obtain and maintain in full force
and effect during the Term directors' and officers' liability insurance policies
providing full and adequate protection to the Employee for his capacities,
provided that the Board shall have no obligation to purchase such insurance if,
in its opinion, coverage is available only on unreasonable terms.

                                      -2-
<PAGE>
 
     4.  Compensation and Benefits.
         ------------------------- 

        (a) Base Salary.  NSI shall pay to the Employee a base salary (the "Base
            -----------                                                      
Salary") at a rate of not less than $[annual salary] per annum, payable in
accordance with NSI's ordinary payroll practices as in effect from time to time
during the Term.  The Board at least annually will review the Base Salary and
other compensation during the Term with a view to the increase thereof based
upon the Employee's performance, the performance of NSI, inflation, then
prevailing industry salary scales and other relevant factors.  Base Salary will
not include any bonus paid to the Employee from time to time.

        (b) Out-of-Pocket Expenses.  NSI shall promptly pay to the Employee the
            ----------------------                                         
reasonable expenses incurred by him in the performance of his duties hereunder,
including, without limitation, those incurred in connection with business
related travel or entertainment, or, if such expenses are paid directly by the
Employee, shall promptly reimburse him for such payment, provided that the
Employee properly accounts therefor in accordance with NSI's policy.

        (c) Participation in Benefit Plans.  The Employee shall be entitled to
            ------------------------------                               
participate in or receive benefits under any pension plan, profit sharing plan,
health and accident plan or any other employee benefit plan or arrangement made
available in the future by NSI to its executives and key management employees,
subject to the terms and conditions applicable to executives and key management
generally.

        (d) Vacation.  The Employee shall be entitled to such paid vacation days
            --------                                                          
in each calendar year as determined by NSI from time to time, but not less than
three (3) weeks in any calendar year, prorated in any calendar year during which
the Employee is employed hereunder for less than an entire year in accordance
with the number of days in such year during which he is so employed.  The
Employee shall also be entitled to all paid holidays given by NSI to its
executives and key management employees.  Such vacation and holiday allowance
shall otherwise be subject to the policies and practices of NSI.

     5.  Termination.
         ----------- 
     The Employee's employment hereunder shall be terminated upon the Employee's
death and may be terminated as follows:

                                      -3-
<PAGE>
 
        (a) By NSI for "Cause."  A termination for Cause is a termination upon a
finding by NSI that the Employee has: (i) intentionally failed to perform
reasonably assigned duties, (ii) engaged in dishonest or willful misconduct in
the performance of his duties, (iii) engaged in a transaction in connection with
the performance of his duties to the Company or any of its Subsidiaries thereof
which transaction is adverse to the interests of the Company or any of its
Subsidiaries and which is engaged in for personal profit by the Employee, or
(iv) willfully violated any law, rule or regulation in connection with the
performance of his duties (other than traffic violations or similar offenses).

        (b) By NSI due to the Employee's "Disability."  For purposes of this
Agreement a termination for Disability shall occur: (i) upon the thirtieth
(30th) day after the issuance of  a written termination notice to the Employee
in the event that the Employee shall have become so incapacitated as to be
unable to resume, within the ensuing six (6) months, his employment hereunder by
reason of physical or mental illness or injury, or (ii) upon the issuance of a
written termination notice after the Employee has been unable to substantially
perform his duties hereunder for three (3) consecutive months by reason of any
physical or mental illness.

     6.  Compensation Upon Termination.
         ----------------------------- 

        (a) In the event of the termination of the Employee's employment as a
result of the Employee's death, NSI shall (i) pay to the Employee's estate his
Base Salary through the date of his death and (ii) for the shorter of one (1)
year following his death or the balance of the Term (as if such termination had
not occurred) provide continuation coverage to the members of the Employee's
family under all Blue Cross/Blue Shield, major medical and other health,
accident, life or other disability plans and programs in which such family
members participated immediately prior to his death.

        (b) In the event of the termination of the Employee's employment by NSI 
for Cause or by the Employee for any reason, NSI shall pay to the Employee his
Base Salary through the date of his termination and the Employee's entitlement
to any other compensation or benefits shall be determined in accordance with
NSI's plans, policies and practices as in effect from time to time.

                                      -4-
<PAGE>
 
        (c) In the event of the termination of the Employee's employment by NSI
due to Disability, NSI shall pay to the Employee his Base Salary through the
date of his termination. In addition, for the shorter of one (1) year following
any such termination or the balance of the Term (as if such termination had not
occurred), NSI shall (i) continue to pay the Employee the Base Salary in effect
at the time of such termination less the amount, if any, then payable to the
Employee under any disability benefits of NSI and (ii) provide the Employee
continuation coverage under all Blue Cross/Blue Shield, major medical and other
health, accident, life or other disability plans and programs in which the
Employee participated immediately prior to such termination, to the extent that
such benefits continue to be made available to active employees of NSI.

        (d) In the event that the Employee's employment is terminated by NSI
other than for Cause or Disability, for a period of one (1) year following any
such termination, NSI shall (i) continue to pay the Employee the Base Salary in
effect at the time of such termination and (ii) provide continuation coverage
under all Blue Cross/Blue Shield, accident, life or other disability plans and
programs in which the Employee participated immediately prior to such
termination, to the extent such benefits continue to be made available to active
employees of NSI. The continuation of Base Salary provided for in clause (i) of
the preceding sentence shall not be reduced by any compensation or other income
that the Employee may earn from subsequent employment or otherwise.

        (e) The continuation coverage under any Blue Cross/Blue Shield, major
medical and other health, accident, life or other disability plans and programs
for the periods provided in Sections 6(a), 6(c) and 6(d) shall be provided (i)
at the expense of NSI and (ii) in satisfaction of NSI's obligation under Section
4980B of the Code (and any similar state law) with respect to the period of time
such benefits are continued hereunder.  Notwithstanding anything to the contrary
contained herein, NSI's obligation to provide such continuation coverage under
Sections 6(a), 6(c) or 6(d) shall cease immediately upon the date any covered
individual becomes eligible for similar benefits under the plans or policies of
another employer.

                                      -5-
<PAGE>
 
        (f) This Section 6 sets forth the only obligations of NSI with respect
to the termination of the Employee's employment with NSI and the Employee
acknowledges that upon his termination of employment he shall not be entitled to
any payments or benefits which are not explicitly provided herein.

     7.  Covenant Regarding Inventions and Copyrights.
         -------------------------------------------- 

     The Employee shall disclose promptly to NSI any and all inventions,
discoveries, improvements and patentable or copyrightable works initiated,
conceived or made by him, either alone or in conjunction with others, during the
Term and related to the business or activities of NSI and he assigns all of his
interest therein to NSI or its nominee; whenever requested to do so by NSI, the
Employee shall execute any and all applications, assignments or other
instruments which NSI shall deem necessary to apply for and obtain letters
patent or copyrights of the United States or any foreign country or otherwise
protect NSI's interest therein.  These obligations shall continue beyond the
conclusion of the Term with respect to inventions, discoveries, improvements or
copyrightable works initiated, conceived or made by the Employee during the Term
and shall be binding upon the Employee's assigns, executors, administrators and
other legal representatives.

     8.  Protection of Confidential Information.
         -------------------------------------- 

     The Employee acknowledges that he has been and will be provided with
information about, and his employment by NSI will, throughout the Term, bring
him into close contact with, many confidential affairs of NSI and its
subsidiaries, including proprietary information about costs, profits, markets,
sales, products, key personnel, pricing policies, operational methods, technical
processes and other business affairs and methods, plans for future developments
and other information not readily available to the public, all of which are
highly confidential and proprietary and all of which were developed by NSI at
great effort and expense.  The Employee further acknowledges that the services
to be performed by him under this Agreement are of a special, unique, unusual,
extraordinary and intellectual character, that the business of NSI will be
conducted throughout the world (the "Territory"), that its products will be
marketed throughout the Territory, that NSI competes and will compete in nearly
all of its

                                      -6-
<PAGE>
 
business activities with other organizations which are located in nearly any
part of the Territory and that the nature of the relationship of the Employee
with NSI is such that the Employee is capable of competing with NSI from nearly
any location in the Territory.  In recognition of the foregoing, the Employee
covenants and agrees during the Term and for a period of five (5) years
thereafter:

          (i)   That he will keep secret all confidential matters of NSI and not
copy them or disclose them to anyone outside of NSI, either during or after the
Term, except with NSI's prior written consent or, if during the Term, in the
performance of his duties hereunder, the Employee makes a good faith
determination that it is in the best interest of NSI to disclose such matters;

          (ii)  That he will not make use of any of such confidential matters
for his own purposes or the benefit of anyone other than NSI; and

          (iii) That he will deliver promptly to NSI on termination of this
Agreement, or at any time NSI may so request, all confidential memoranda, notes,
records, reports and other confidential documents (and all copies thereof)
relating to the business of NSI, which he may then possess or have under his
control.

     9.  Restriction on Competition, Interference and Solicitation.
         --------------------------------------------------------- 

     In recognition of the considerations described in Section 8 hereof, the
Employee covenants and agrees that, during the Term and for a period of two (2)
years after the termination of his employment hereunder, the Employee will not,
directly or indirectly, (A) enter into the employ of, or render any services to,
any person, firm or corporation engaged in any business competitive with the
business of NSI in any part of the Territory; (B) engage in any such business
for his account; (C) become interested in any such business as an individual,
partner, shareholder, creditor, director, officer, principal, agent, employee,
trustee, consultant advisor, franchisee or in any other relationship or
capacity; or (D) interfere with NSI's relationship with, or endeavor to employ
or entice away from NSI any person, firm, corporation, governmental entity or
other business organization who or which is or was an employee, customer or
supplier of, or maintained a business relationship with, NSI at any time
(whether before, during or after the

                                      -7-
<PAGE>
 
Term), or which NSI has solicited or prepared to solicit; provided, however,
                                                          --------  ------- 
that nothing contained in this Section 9 shall be deemed to prohibit the
Employee from acquiring or holding, solely for investment, publicly traded
securities of any corporation some of the activities of which are competitive
with the business of NSI so long as such securities do not, in the aggregate,
constitute more than five percent (5%) of any class or series of outstanding
securities of such corporation.

     10.  Specific Remedies.
          ----------------- 

     For purposes of Sections 7, 8 and 9 of this Agreement, references to NSI
shall include all current and future majority-owned subsidiaries of NSI and all
current and future joint ventures in which NSI may from time to time be
involved.  It is understood by the Employee and NSI that the covenants contained
in this Section 10 and in Sections 7, 8, and 9 hereof are essential elements of
this Agreement and that, but for the agreement of the Employee to comply with
such covenants, NSI would not have agreed to enter into this Agreement.  NSI and
the Employee have independently consulted with their respective counsel and have
been advised concerning the reasonableness and propriety of such covenants with
specific regard to the nature of the business conducted by NSI and the interests
of NSI and its stockholders.  The Employee agrees that the covenants of Sections
7, 8, and 9 are reasonable and valid.  If the Employee commits a breach of any
of the provisions of Sections 7, 8, or 9, such breach shall be deemed to be
grounds for termination for Cause.  In addition, the Employee acknowledges that
NSI may have no adequate remedy at law if he violates any of the terms hereof.
The Employee therefore understands and agrees that NSI shall have (i) the right
to have such provisions specifically enforced by any court having equity
jurisdiction, it being acknowledged and agreed that any such breach will cause
irreparable injury to NSI and that money damages will not provide an adequate
remedy to NSI, and (ii) the right to require the Employee to account for and pay
over to NSI all compensation, profits, monies, accruals, increments and other
benefits (collectively, the "Benefits") derived or received by the Employee as a
result of any transaction constituting a willful breach of any of the provisions
of Sections 7, 8, or 9 and the Employee hereby agrees to account for and pay
over such Benefits to NSI.

                                      -8-
<PAGE>
 
     11.  Independence, Severability and Non-Exclusivity.
          ---------------------------------------------- 

     Each of the rights enumerated in Section 10 hereof shall be independent of
the others and shall be in addition to and not in lieu of any other rights and
remedies available to NSI at law or in equity.  If any of the covenants
contained in Sections 7, 8, or 9, or any part of any of them, is hereafter
construed or adjudicated to be invalid or unenforceable, the same shall not
affect the remainder of the covenant or covenants or rights or remedies which
shall be given full effect without regard to the invalid portions.  The parties
intend to and do hereby confer jurisdiction to enforce the covenants contained
in Sections 7, 8, or 9 and the remedies enumerated in Section 10 upon the
federal and state courts of New York sitting in New York County.  If any of the
covenants contained in Sections 7, 8, or 9 is held to be invalid or
unenforceable because of the duration of such provision or the area covered
thereby, the parties agree that the court making such determination shall have
the power to reduce the duration and/or area of such provision and in its
reduced form said provision shall then be enforceable.  No such holding of
invalidity or unenforceability in one jurisdiction shall bar or in any way
affect NSI's right to the relief provided in Section 10 or otherwise in the
courts of any other state or jurisdiction within the geographical scope of such
covenants as to breaches of such covenants in such other respective states of
jurisdictions, such covenants being, for this purpose, severable into diverse
and independent covenants.

     12.  Disputes.
          -------- 
     If NSI or the Employee shall dispute any termination of the Employee's
employment hereunder or if a dispute concerning any payment hereunder shall
exist:

        (a) either party shall have the right (but not the obligation), in
addition to all other rights and remedies provided by law, to compel arbitration
of the dispute in the City of New York under the rules of the American
Arbitration Association by giving written notice of arbitration to the other
party within thirty (30) days after notice of such dispute has been received by
the party to whom notice has been given; and

        (b) if such dispute (whether or not submitted to arbitration pursuant to
Section 12(a) hereof) results in a determination that (i) NSI did not have the
right to terminate the

                                      -9-
<PAGE>
 
Employee's employment under the provisions of this Agreement or (ii) the
position taken by the Employee concerning payments to the Employee is correct,
NSI shall promptly pay, or if theretofore paid by the Employee, shall promptly
reimburse the Employee for, all costs and expenses (including attorney's fees)
reasonably incurred by the Employee in connection with such dispute.

     13.  Successors; Binding Agreement.
          ----------------------------- 

     In the event of a future disposition by NSI (whether direct or indirect, by
sale of assets or stock, merger, consolidation or otherwise) of all or
substantially all of its business and/or assets in a transaction to which the
Employee consents, NSI will require any successor, by agreement in form and
substance satisfactory to the Employee, to expressly assume and agree to perform
this Agreement in the same manner and to the same extent that NSI would be
required to perform if no such disposition had taken place.

     This Agreement and all rights of the Employee hereunder shall inure to the
benefit of, and be enforceable by, the Employee's personal or legal
representatives, executors, administrators, administrators c.t.a., successors,
heirs, distributees, devisees and legatees.  Unless otherwise provided herein,
any amounts payable hereunder after the Employee's death shall be paid in
accordance with the terms of this Agreement to the Employee's estate.

     14.  Notices.
          ------- 

     All notices, consents or other communications required or permitted to be
given by any party hereunder shall be in writing (including telecopy or other
similar writing) and shall be given by personal delivery, certified or
registered mail, postage prepaid, or telecopy (or other similar writing) as
follows:

          To NSI:
                     Attn:  General Counsel
                     Two Executive Boulevard
                     Suffern, New York,  10901-4414

                                      -10-
<PAGE>
 
          To the Employee:

                     C/O Neuromedical Systems, Inc.
                     Two Executive Boulevard
                     Suffern, New York,  10901-4414

or at such other address or telecopy number (or other similar number) as either
party may from time to time specify to the other.  Any notice, consent or other
communication required or permitted to be given hereunder shall be deemed to
have been given on the date of mailing, personal delivery or telecopy or other
similar means thereof (provided the appropriate answer back is received) and
shall be conclusively presumed to have been received on the second business day
following the date of mailing or, in the case of personal delivery or telecopy
or other similar means, the day of delivery thereof, except that a change of
address shall not be effective until actually received.

     15.  Modifications and Waivers.
          ------------------------- 

     No term, provision or condition of this Agreement may be modified or

                              EMPLOYMENT AGREEMENT
                              --------------------

     AGREEMENT, effective as of the 1st day of June, 1997, by and between
NEUROMEDICAL SYSTEMS, INC., a Delaware corporation with principal executive
offices at Two Executive Boulevard, Suffern, New York 10901-4114 ("NSI"), and
Stephen K.C. Ng, M.D. (the "Employee").

                             W I T N E S S E T H :

     WHEREAS, the Employee was previously employed as president of Papnet (Far
East) Ltd. ("PFEL"), a Cayman Islands corporation;
     WHEREAS, the Employee is currently employed by New System International
Ltd. ("New Sys"), a Hong Kong corporation and former subsidiary of PFEL;

     WHEREAS, all of the capital stock of New Sys was acquired from PFEL as of
the date set forth above by NSI Asia Pacific Ltd. ("NSI-APL"), a Cayman Islands
corporation and wholly owned subsidiary of NSI; and

          WHEREAS, NSI is desirous to employ the Employee as President of NSI-
APL and its subsidiaries, and the Employee is desirous to serve NSI in such
capacity, all upon the terms and subject to the conditions hereinafter provided.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereto, intending to be legally bound, agree as
follows:

     1.  Employment.
         ---------- 
     NSI agrees to employ the Employee, and the Employee agrees to be employed
by NSI, upon the terms and subject to the conditions of this Agreement.

     2.  Term.
         ---- 
     The employment of the Employee by NSI as provided in Section 1 will be for
the period commencing on the date hereof (the "Commencement Date") and ending
<PAGE>
 
on the first (1st) anniversary of the Commencement Date (the "Term"); provided,
however, on the first anniversary of the Commencement Date and on each
anniversary thereafter, the Term shall be automatically extended for an
additional period of one (1) year, unless either party gives written notice to
the other at least ninety (90) days prior thereto that the Term of this
Agreement shall not be so extended; provided, further, however, that the Term
may be earlier terminated as hereinafter provided.

     3.  Duties; Best Efforts; Indemnification.
         ------------------------------------- 

     The Employee shall serve as President of NSI-APL, or such other senior
management level position(s) as the Board of Directors of NSI (the "Board") may
from time to time and in its reasonable discretion appoint the Employee, and
shall perform and discharge well and faithfully the duties which may from time
to time be prescribed by the President and Chief Executive Officer of NSI.  The
Employee shall devote 90% all of his business time, attention and energies to
the business and affairs of NSI-APL and its subsidiaries, shall use his best
efforts to advance the best interests of NSI-APL and its subsidiaries, and shall
not, except for 10% of his time during the Term which may be devoted to non-
competing consultation activities, be actively engaged in any other business
activity, whether or not such business activity is pursued for gain, profit or
other pecuniary advantage.

     Subject to the provisions of NSI's Certificate of Incorporation and Bylaws,
each as amended from time to time, NSI shall indemnify the Employee to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as amended from time to time, for all amounts (including without
limitation, judgments, fines, settlement payments, expenses and attorney's fees)
incurred or paid by the Employee in connection with any action, suit,
investigation or proceeding arising out of or relating to the performance by the
Employee of services for, or the acting by the Employee as an officer or
employee of, NSI, or any other person or enterprise at NSI's request; provided,
however, that NSI shall not be required to indemnify the Employee against any
liability

                                      -2-
<PAGE>
 
resulting from conduct which is willful, intentional or grossly negligent.  NSI
shall use its best efforts to obtain and maintain in full force and effect
during the Term directors' and officers' liability insurance policies providing
full and adequate protection to the Employee for his capacities, provided that
the Board of Directors of NSI (the "Board") shall have no obligation to purchase
such insurance if, in its opinion, coverage is available only on unreasonable
terms.

     4.  Compensation and Benefits.
         ------------------------- 

        (a) Base Salary.  NSI shall pay to the Employee a base salary (the "Base
            -----------                                                         
Salary") at a rate of not less than US$174,000 per annum, payable in twelve (12)
equal monthly installments in arrears and in accordance with NSI's ordinary
payroll practices as in effect from time to time during the Term.  The Board at
least annually will review the Base Salary and other compensation during the
Term with a view to the increase thereof based upon the Employee's performance,
the performance of NSI, inflation, then prevailing industry salary scales and
other relevant factors.  Base Salary will not include any bonus paid to the
Employee from time to time.

        (b) Out-of-Pocket Expenses.  NSI shall promptly pay to the Employee the
            ----------------------                                             
reasonable expenses incurred by him in the performance of his duties hereunder,
including, without limitation, those incurred in connection with business
related travel or entertainment, or, if such expenses are paid directly by the
Employee, shall promptly reimburse him for such payment, provided that the
Employee properly accounts therefor in accordance with NSI's policy.

        (c) Participation in Benefit Plans.  The Employee shall be entitled to
            ------------------------------                                    
participate in or receive benefits under any pension plan, profit sharing plan,
health and accident plan or any other employee benefit plan or arrangement made
available in the future by NSI to its executives and key management employees,
subject to the terms and conditions applicable to executives and key management
generally.

        (d) Vacation.  The Employee shall be entitled to such paid vacation days
            --------                                                          
in each calendar year as determined by NSI from time to time, but not less than
three (3) weeks in any calendar year, prorated in any calendar year during which
the Employee is employed hereunder for less than an entire year in accordance
with the number of days in such year during which he is so employed.  The
Employee shall also be entitled to all paid holidays given by NSI to its
executives and key management employees.  Such vacation and holiday allowance
shall otherwise be subject to the policies and practices of NSI.

        (e) Housing Allowance.  NSI shall pay to the Employee an annual housing
            -----------------                                                  
allowance of US$60,000, payable in twelve equal monthly installments in arrears.

        (f) Bonus.  NSI shall pay to the Employee an annual bonus equal to the
            -----                                                             
higher of one (1) month Base Salary or such greater amount granted by the Board
(i.e., a minimum of one (1) month Base Salary is guaranteed as an annual bonus
payment by NSI to the Employee).  Such bonus shall be paid at the earlier of
twelve (12) months following the effective date hereof or at the date of grant
of a bonus to Employee by the Board.

        (g) Stock Options Grant.  Employee shall be eligible to receive stock
            -------------------                                              
options for the purchase of NSI Common Stock in accordance with the terms and
conditions of the NSI 1993 Stock Incentive Plan, as amended and restated October
25, 1995, with such additional terms and conditions of the Board as determined
in accordance therewith.  The initial stock option grant to Employee following
execution of this Agreement shall be for 40,000 shares of NSI Common Stock,
which shall be exercisable at a purchase price of $4.00 per share and which will
vest over a four (4) year period, becoming exercisable at a rate of 25% per year
as of July 28th of each year (i.e., 25% will become exercisable on July 28, 1998
and an additional 25% each year thereafter until fully vested on July 28, 2001);
the amount of grant eligibility in subsequent years shall be determined by the
Board upon renewal of this Agreement.

                                      -4-

        (h) Taxes.  Any and all taxes payable by Employee are the sole
            -----                                                     
responsibility of the Employee, provided, however, that NSI shall comply with
                                --------  -------                            
any and all applicable tax laws with respect to the withholding of amounts from
Employee compensation subject to U.S. federal, state, and local taxes, and any
other jurisdictional taxes with respect to which NSI and/or its subsidiaries
have a legal obligation of compliance.

     5.  Termination.
         ----------- 

     The Employee's employment hereunder shall be terminated upon the Employee's
death and may be terminated as follows:

        (a) By NSI for "Cause."  A termination for Cause is a termination upon a
finding by NSI that the Employee has (i) intentionally failed to perform
reasonably assigned duties, (ii) engaged in dishonest or willful misconduct in
the performance of his duties, (iii) engaged in a transaction in connection with
the performance of his duties to the Company or any of its Subsidiaries thereof
which transaction is adverse to the interests of the Company or any of its
Subsidiaries and which is engaged in for personal profit by the Employee, or
(iv) willfully violated any law, rule or regulation in connection with the
performance of his duties (other than traffic violations or similar offenses).

        (b) By NSI due to the Employee's "Disability."  For purposes of this
Agreement a termination for Disability shall occur (i) upon the thirtieth (30th)
day after the issuance of  a written termination notice to the Employee in the
event that the Employee shall have become so incapacitated as to be unable to
resume, within the ensuing six (6) months, his employment hereunder by reason of
physical or mental illness or injury, or (ii) upon the issuance of a written
termination notice after the Employee has been unable to substantially perform
his duties hereunder for three (3) consecutive months by reason of any physical
or mental illness.

<PAGE>
 
     6.  Compensation Upon Termination.
         ----------------------------- 

        (a) In the event of the termination of the Employee's employment as a
result of the Employee's death, NSI shall (i) pay to the Employee's estate his
Base Salary through the date of his death and (ii) for the shorter of one (1)
year following his death or the balance of the Term (as if such termination had
not occurred) provide continuation coverage to the members of the Employee's
family under all Blue Cross/Blue Shield, major medical and other health,
accident, life or other disability plans and programs in which such family
members participated immediately prior to his death.

        (b) In the event of the termination of the Employee's employment by NSI 
for Cause or by the Employee for any reason, NSI shall pay to the Employee his
Base Salary through the date of his termination and the Employee's entitlement
to any other compensation or benefits shall be determined in accordance with
NSI's plans, policies and practices as in effect from time to time.

        (c) In the event of the termination of the Employee's employment by NSI
due to Disability, NSI shall pay to the Employee his Base Salary through the
date of his termination. In addition, for the shorter of one (1) year following
any such termination or the balance of the Term (as if such termination had not
occurred), NSI shall (i) continue to pay the Employee the Base Salary in effect
at the time of such termination less the amount, if any, then payable to the
Employee under any disability benefits of NSI, and (ii) provide the Employee
continuation coverage under all Blue Cross/Blue Shield, major medical and other
health, accident, life or other disability plans and programs in which the
Employee participated immediately prior to such termination, to the extent that
such benefits continue to be made available to active employees of NSI.

        (d) In the event that the Employee's employment is terminated by NSI
other than for Cause or Disability, for a period of one (1) year following any
such termination, NSI shall (i) continue to pay the Employee the Base Salary in
effect at the time of such termination, and (ii) provide continuation coverage
under all Blue

                                      -6-
<PAGE>
 
Cross/Blue Shield, accident, life or other disability plans and programs in
which the Employee participated immediately prior to such termination, to the
extent such benefits continue to be made available to active employees of NSI.
The continuation of Base Salary provided for in clause (i) of the preceding
sentence shall not be reduced by any compensation or other income that the
Employee may earn from subsequent employment or otherwise.

        (e) The continuation coverage under any Blue Cross/Blue Shield, major
medical and other health, accident, life or other disability plans and programs
for the periods provided in Sections 6(a), 6(c) and 6(d) shall be provided (i)
at the expense of NSI, and (ii) in satisfaction of NSI's obligation under
Section 4980B of the Code (and any similar state law) with respect to the period
of time such benefits are continued hereunder.  Notwithstanding anything to the
contrary contained herein, NSI's obligation to provide such continuation
coverage under Sections 6(a), 6(c) or 6(d) shall cease immediately upon the date
any covered individual becomes eligible for similar benefits under the plans or
policies of another employer.

        (f) This Section 6 sets forth the only obligations of NSI with respect
to the termination of the Employee's employment with NSI and the Employee
acknowledges that upon his termination of employment he shall not be entitled to
any payments or benefits which are not explicitly provided herein.

     7.  Covenant Regarding Inventions and Copyrights.
         -------------------------------------------- 

     The Employee shall disclose promptly to NSI any and all inventions,
discoveries, improvements and patentable or copyrightable works initiated,
conceived or made by him, either alone or in conjunction with others, during the
Term and related to the business or activities of NSI and he assigns all of his
interest therein to NSI or its nominee; whenever requested to do so by NSI, the
Employee shall execute any and all applications, assignments or other
instruments which NSI shall deem necessary to apply for and obtain letters
patent or copyrights of the United States or any foreign country or

                                      -7-
<PAGE>
 
otherwise protect NSI's interest therein.  These obligations shall continue
beyond the conclusion of the Term with respect to inventions, discoveries,
improvements or copyrightable works initiated, conceived or made by the Employee
during the Term and shall be binding upon the Employee's assigns, executors,
administrators and other legal representatives.

     8.  Protection of Confidential Information.
         -------------------------------------- 

     The Employee acknowledges that he has been and will be provided with
information about, and his employment by NSI will, throughout the Term, bring
him into close contact with, many confidential affairs of NSI and its
subsidiaries, including proprietary information about costs, profits, markets,
sales, products, key personnel, pricing policies, operational methods, technical
processes and other business affairs and methods, plans for future developments
and other information not readily available to the public, all of which are
highly confidential and proprietary and all of which were developed by NSI at
great effort and expense.  The Employee further acknowledges that the services
to be performed by him under this Agreement are of a special, unique, unusual,
extraordinary and intellectual character, that the business of NSI will be
conducted throughout the world (the "Territory"), that its products will be
marketed throughout the Territory, that NSI competes and will compete in nearly
all of its business activities with other organizations which are located in
nearly any part of the Territory and that the nature of the relationship of the
Employee with NSI is such that the Employee is capable of competing with NSI
from nearly any location in the Territory.  In recognition of the foregoing, the
Employee covenants and agrees during the Term and for a period of five (5) years
thereafter:

        (i) That he will keep secret all confidential matters of NSI and not
copy them or disclose them to anyone outside of NSI, either during or after the
Term, except with NSI's prior written consent or, if during the Term, in the
performance of his

                                      -8-
<PAGE>
 
duties hereunder, the Employee makes a good faith determination that it is in
the best interest of NSI to disclose such matters;

       (ii)  That he will not make use of any of such confidential matters for
his own purposes or the benefit of anyone other than NSI; and

      (iii)  That he will deliver promptly to NSI on termination of this

     9.  Restriction on Competition, Interference and Solicitation.
         --------------------------------------------------------- 

     In recognition of the considerations described in Section 8 hereof, the
Employee covenants and agrees that, during the Term and for a period of two (2)
years after the termination of his employment hereunder, the Employee will not,
directly or indirectly; (A) enter into the employ of, or render any services to,
any person, firm or corporation engaged in any business competitive with the
business of NSI in any part of the Territory; (B) engage in any such business
for his account; (C) become interested in any such business as an individual,
partner, shareholder, creditor, director, officer, principal, agent, employee,
trustee, consultant advisor, franchisee or in any other relationship or
capacity; or (D) interfere with NSI's relationship with, or endeavor to employ
or entice away from NSI any person, firm, corporation, governmental entity or
other business organization who or which is or was an employee, customer or
supplier of, or maintained a business relationship with, NSI at any time
(whether before, during or after the Term), or which NSI has solicited or
prepared to solicit; provided, however, that nothing contained in this Section 9
                     --------  -------                                          
shall be deemed to prohibit the Employee from acquiring or holding, solely for
investment, publicly traded securities of any corporation some of the activities
of which are competitive with the business of NSI so long as such securities do
not, in the aggregate, constitute more than five percent (5%) of any class or
series of outstanding securities of such corporation.

     10.  Specific Remedies.
          ----------------- 

     For purposes of Sections 7, 8 and 9 of this Agreement, references to NSI
shall include all current and future majority-owned subsidiaries of NSI and all
current and future joint ventures in which NSI may from time to time be
involved.  It is understood by the Employee and NSI that the covenants contained
in this Section 10 and in Sections 7, 8, and 9 hereof are essential elements of
this Agreement and that, but for the agreement of the Employee to comply with
such covenants, NSI would not have agreed to enter into this Agreement.  NSI and
the Employee have independently consulted with their respective counsel and have
been advised concerning the reasonableness and propriety of such covenants with
specific regard to the nature of the business conducted by NSI and the interests
of NSI and its stockholders.  The Employee agrees that the covenants of Sections
7, 8, and 9 are reasonable and valid.  If the Employee commits a breach of any
of the provisions of Sections 7, 8, or 9, such breach shall be deemed to be
grounds for termination for Cause.  In addition, the Employee acknowledges that
NSI may have no adequate remedy at law if he violates any of the terms hereof.
The Employee therefore understands and agrees that NSI shall have: (i) the right
to have such provisions specifically enforced by any court having equity
jurisdiction, it being acknowledged and agreed that any such breach will cause
irreparable injury to NSI and that money damages will not provide an adequate
remedy to NSI, and (ii) the right to require the Employee to account for and pay
over to NSI all compensation, profits, monies, accruals, increments and other
benefits (collectively, the "Benefits") derived or received by the Employee as a
result of any transaction constituting a willful breach of any of the provisions
of Sections 7, 8, or 9 and the Employee hereby agrees to account for and pay
over such Benefits to NSI.

     11.  Independence, Severability and Non-Exclusivity.
          ---------------------------------------------- 

     Each of the rights enumerated in Section 10 hereof shall be independent of
the others and shall be in addition to and not in lieu of any other rights and
remedies

                                      -10-
<PAGE>
 
available to NSI at law or in equity.  If any of the covenants contained in
Sections 7, 8, or 9, or any part of any of them, is hereafter construed or
adjudicated to be invalid or unenforceable, the same shall not affect the
remainder of the covenant or covenants or rights or remedies which shall be
given full effect without regard to the invalid portions.  The parties intend to
and do hereby confer jurisdiction to enforce the covenants contained in Sections
7, 8, or 9 and the remedies enumerated in Section 10 upon the federal and state
courts of New York sitting in New York County.  If any of the covenants
contained in Sections 7, 8, or 9 is held to be invalid or unenforceable because
of the duration of such provision or the area covered thereby, the parties agree
that the court making such determination shall have the power to reduce the
duration and/or area of such provision and in its reduced form said provision
shall then be enforceable.  No such holding of invalidity or unenforceability in
one jurisdiction shall bar or in any way affect NSI's right to the relief
provided in Section 10 or otherwise in the courts of any other state or
jurisdiction within the geographical scope of such covenants as to breaches of
such covenants in such other respective states of jurisdictions, such covenants
being, for this purpose, severable into diverse and independent covenants.

     12.  Disputes.
          -------- 
     If NSI or the Employee shall dispute any termination of the Employee's
employment hereunder or if a dispute concerning any payment hereunder shall
exist:

         (a) either party shall have the right (but not the obligation), in
addition to all other rights and remedies provided by law, to compel arbitration
of the dispute in the City of New York under the rules of the American
Arbitration Association by giving written notice of arbitration to the other
party within thirty (30) days after notice of such dispute has been received by
the party to whom notice has been given; and

         (b) if such dispute (whether or not submitted to arbitration pursuant
to Section 12(a) hereof) results in a determination that: (i) NSI did not have
the right to terminate the Employee's employment under the provisions of this
Agreement, or (ii) the

                                      -11-
<PAGE>
 
position taken by the Employee concerning payments to the Employee is correct,
NSI shall promptly pay, or if theretofore paid by the Employee, shall promptly
reimburse the Employee for, all costs and expenses (including attorney's fees)
reasonably incurred by the Employee in connection with such dispute.

     13.  Successors; Binding Agreement.
          ----------------------------- 

     In the event of a future disposition by NSI (whether direct or indirect, by
sale of assets or stock, merger, consolidation or otherwise) of all or
substantially all of its business and/or assets in a transaction to which the
Employee consents, NSI will require any successor, by agreement in form and
substance satisfactory to the Employee, to expressly assume and agree to perform
this Agreement in the same manner and to the same extent that NSI would be
required to perform if no such disposition had taken place.

     This Agreement and all rights of the Employee hereunder shall inure to the
benefit of, and be enforceable by, the Employee's personal or legal
representatives, executors, administrators, administrators c.t.a., successors,
heirs, distributees, devisees and legatees.  Unless otherwise provided herein,

accordance with the terms of this Agreement to the Employee's estate.

                             W I T N E S S E T H :
     WHEREAS, NSI Netherlands B.V. is a wholly owned subsidiary of NSI;

     WHEREAS, the Employee is currently employed by NSI Netherlands B.V. as
President pursuant to an employment contract between the Employee and NSI
Netherlands B.V., dated October 8, 1996 (the "Existing Agreement");

          WHEREAS, NSI is desirous of continuing to employ the Employee of NSI
in such capacity, and the Employee is desirous of continuing to serve NSI in
such capacity, all upon the terms and subject to the conditions hereinafter
provided; and

     WHEREAS, NSI, NSI Netherlands B.V. and the Employee desire to amend the
Existing Agreement so as to provide for the addition to the Existing Agreement
of the terms and conditions contained herein.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein contained, the parties hereto, intending to be legally bound, agree as
follows:
     1.  Compensation.
         ------------ 
         NSI shall pay to the Employee a base salary at a rate of not less than

<PAGE>
 
     2.  Indemnification.
         --------------- 
     Subject to the provisions of NSI's Certificate of Incorporation and Bylaws,
each as amended from time to time, NSI shall indemnify the Employee to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as amended from time to time, for all amounts (including without
limitation, judgments, fines, settlement payments, expenses and attorney's fees)
incurred or paid by the Employee in connection with any action, suit,
investigation or proceeding arising out of or relating to the performance by the
Employee of services for, or the acting by the Employee as an officer or
employee of, NSI, or any other person or enterprise at NSI's request; provided,
however, that NSI shall not be required to indemnify the Employee against any
liability resulting from conduct which is willful, intentional or grossly

     The Employee's employment hereunder shall be terminated upon the Employee's
death and may be terminated as follows:

performance of his duties to the Company or any of its Subsidiaries thereof
which transaction is adverse to the interests of the Company or any of its
Subsidiaries and which is engaged in for personal profit by the Employee or (iv)

performance of his duties (other than traffic violations or similar offenses).

     4.  Compensation Upon Termination.
         ----------------------------- 
        (a) In the event of the termination of the Employee's employment as a
result of the Employee's death, NSI shall (i) pay to the Employee's estate his
Base Salary through the date of his death and (ii) for the shorter of one (1)
year following his death or the balance of the Term (as if such termination had
not occurred) provide continuation coverage to the members of the Employee's
family under all major medical and other health, accident, life or other
disability plans and programs in which such family members participated
immediately prior to his death.
        (b) In the event of the termination of the Employee's employment by NSI
for Cause or by the Employee for any reason, NSI shall pay to the Employee his
Base Salary through the date of his termination and the Employee's entitlement
to any other compensation or benefits shall be determined in accordance with
NSI's plans, policies and practices as in effect from time to time.
        (c) In the event that the Employee's employment is terminated by NSI
other than for Cause, for a period of one (1) year following any such
termination, NSI shall (i) continue to pay the Employee the Base Salary in
effect at the time of such termination and (ii) provide continuation coverage
under all accident, life or other disability plans and programs in which the
Employee participated immediately prior to

                                      -10-
<PAGE>
 
such termination, to the extent such benefits continue to be made available to
active employees of NSI.  The continuation of Base Salary provided for in clause
(i) of the preceding sentence shall not be reduced by any compensation or other
income that the Employee may earn from subsequent employment or otherwise.
        (d) This Section 3 sets forth the only obligations of NSI with respect
to the termination of the Employee's employment with NSI and the Employee
acknowledges that upon his termination of employment he shall not be entitled to
any payments or benefits which are not explicitly provided in the Existing
Agreement, herein above or as otherwise required by law.

page hereto (collectively the "PFEL Stockholders").  Capitalized terms in this
Agreement shall have the meanings set forth in Section 9 herein.

WHEREAS  New System International, Ltd., a Hong Kong corporation (the "Company")
is in the business of providing PAPNET (R) Pap smear testing services in Hong
Kong

WHEREAS   the total authorized capital stock of the Company consists of 10,000
ordinary shares of HK$1 par value per share, all of which have been issued and
are fully paid

WHEREAS  the Seller beneficially owns all 10,000 issued shares of the Company
(the "Shares") of which 9,999 shares are registered in the name of the Seller
and 1 share is registered in the name of Rose Beauty Ltd. which holds the same
as nominee for the Seller

WHEREAS  the Company is indebted to the Seller in the amount of the Loan

WHEREAS  the Buyer desires to purchase from the Seller and the Seller desires to
sell to the Buyer the Shares and the Loan on the terms and conditions of this
Agreement

Now, therefore, in consideration of the premises and the mutual promises herein
made, and in consideration of the representations, warranties, and covenants
herein contained of which the adequacy and sufficiency of such consideration is
expressly acknowledged by the Buyer and the Seller, the parties hereto agree as
follows.

1.    BASIC TRANSACTION.
     ------------------ 

(a)  Purchase and Sale of Shares and Loan.
     ------------------------------------ 

On and subject to the terms and conditions of this Agreement, the Buyer agrees
to purchase from  the Seller the Shares and the Loan, and the Seller agrees to
deliver and transfer to the Buyer, the Shares and the Loan free and clear of all
claims, liens or encumbrances at the Closing for the consideration specified in
paragraph (c) below in this Section 1.

(b)    Effective Time.
       -------------- 
The time of the Closing shall be "the Effective Time".

(c)    Purchase Price.
       ---------------

(i)  The amount payable by the Buyer shall be calculated in accordance with the
following: the base value of the Shares and the Loan shall be US$1,409,000 (One
Million Four Hundred

                                       1
<PAGE>
 
Thousand United States Dollars) (the "Base Purchase Price"), which shall be
adjusted in accordance with the calculations set forth on the pro-forma balance
sheet of the Company as at May 30, 1997 (the "Pro-Forma Closing Accounts")
attached hereto as Exhibit A, to reflect (1) addition to the Base Purchase Price
of amounts equal to operating losses of the Company since December 1, 1996, such
amount not to exceed US$50,000 per month; (2) addition to the Base Purchase
Price of amounts equal to cash balances remaining in the Hong Kong and Beijing
bank accounts of the Seller; (3) deduction from the Base Purchase Price of
Liabilities payable by the Company (excluding the Loan) and (4) addition or
deduction, as the case may be, of the net increase or decrease in the Company's
book value of its Accounts Receivable balance from December 1, 1996 through May
30, 1997. The Base Purchase Price as adjusted in accordance with Exhibit A shall
be referred to hereinafter as the "Adjusted Purchase Price" which shall be
apportioned US$10,000.00 to the Shares and US$1,765,113.00 to the Loan.

(ii)    The Buyer shall be entitled to retain a sum equal to the Outstanding
Receivables or US$200,000, whichever is the lesser amount (the "Retention Fund")
as security for the receipt by the Company of the Outstanding Receivables. The
Buyer shall use its best endeavours to recover payment of the Outstanding
Receivables within a 180 day period from Closing. Buyer shall render monthly
statements to Seller as to the payment status of such Outstanding Receivables
and shall with each such statement remit to the Seller any Outstanding
Receivable amounts paid to the Company during the period covered by such
statement. The Buyer shall not be obliged to take further action to recover any
amount not paid within the period of 180 days from the Closing Date and shall be
entitled to apply any remaining balance in the Retention Fund as consideration
for the assignment of the remaining Outstanding Receivables from the Company to
the Seller. The Company shall execute an assignment thereof to the Seller so
that the Seller may take action to recover the same in its own name.

(iii)    In the event that the Company's year-end audit discloses that the
Liabilities (excluding the Loan) are found to exceed those stated in the Pro-
Forma Closing Accounts, there shall be a reduction of the Adjusted Purchase
price by the total amount of such excess.  The Seller shall promptly deliver to
the Buyer any balance due thereof.  If such audit discloses a greater cash
balance and/or a lesser amount of Liabilities payable at Closing than as set
forth in the Pro-Forma Closing Accounts, the Buyer shall promptly remit to the
Seller the difference of any such amounts.

(d)    The Closing.
       ----------- 

The closing of the transactions contemplated by this Agreement (the "Closing")
shall take place at the offices of the Company in Hong Kong  upon the execution
of this Agreement, but the rights of the Buyer to the Shares shall be deemed to
have accrued as from 1st June 1997.

(e)  Deliveries at the Closing.
     ------------------------- 

At the Closing, (i) the Seller will execute, acknowledge and deliver to the
Buyer the various Exhibits, Schedules, certificates, instruments, and documents
referred to herein, such other instruments of sale, transfer and conveyance
satisfactory to the Buyer as shall be effective for Buyer to take full, valid
and enforceable right, title and ownership interest of the Shares and the Loan
and such other documents that Buyer may reasonably request and (ii) Buyer will
deliver to the Seller the consideration specified in Section 1(c) above.

          names for operation of the Business which shall be effective
          simultaneously upon termination of the License Agreement; such name
          changes shall include, but not be limited to, any and all required
          corporate, authorized, official, commercial, trade and/or assumed
          names, and any other name or mark of Seller or the Business that have
          a near resemblance thereto with respect to the Business.  In addition,
          if deemed reasonably necessary by Buyer, Seller shall amend its
          Articles of Incorporation to change its corporate name.  In accordance
          with the License Agreement, Buyer hereby grants to Seller, at the
          Effective Time, the right to continue to use any and all of Seller's
          authorized, official, commercial, trade and/or assumed names on
          existing packaging, stationery and purchase order forms and any other
          printed materials until the termination of the License Agreement or
          earlier if so notified by Buyer.  Seller will take any and all further
          action reasonably necessary to carry out the foregoing name changes
          including, but not be limited to, the execution and delivery of such
          further instruments and documents, registration of such changed names
          with any and all required Taiwan legal authorities, and reasonable
          notice to each and every employee, lessor, licensor, customer,
          supplier, or other business associate of the Business so as to
          maintain the same business relationships with the Buyer after the name
          changes as such person maintained with the Business in the Ordinary
          Course of Business prior to such name changes.



     (g)  Subleases, Sublicenses and Subcontracts.
          --------------------------------------- 

          Immediately prior to the termination of the License Agreement, Seller
          shall promptly take any and all action necessary to legally sublease,
          sublicense or subcontract, as the case may be, to Buyer, (i) each of
          the lease and contract

                                      -19-

          agreements specified in paragraphs (j) and (l) of Section 2 above,
          each such sub-agreement to be legal, valid, binding, enforceable, and

          agreement which is the subject of such sub-agreement.



     (h)  Seller further covenants that it shall maintain itself as a
          corporation duly organized, validly existing, and in good standing
          under the laws of Taiwan, with full corporate power and authority to
          conduct business in Taiwan during the term of the License Agreement
          and during the terms of any and all sublicenses entered into pursuant
          to paragraph (g) above.

          insurance for replacement of the Assets, such insurance to include
          coverage for continuation of the Business in the event of fire, flood,
          theft, or other similar event which would cause loss of the Assets or
          loss of use of the Business premises.  Such insurance coverage shall
          be upon reasonable terms and conditions which are customary for
          similarly situated businesses purchasing similar types of risk
          coverage.  The policy thereof shall be effective under the terms of
          the License Agreement, and shall be transferable to the Buyer upon
          termination of the License Agreement.  Buyer shall reimburse Seller
          for the cost of such insurance policy in accordance with the terms of
          the License Agreement.

          warranties, and covenants contained in this Agreement provided that
          the Buyer makes a written claim for indemnification against the
          Seller, then the Seller agrees to indemnify hold harmless and defend

          Consequences the Buyer may suffer so long as such Material Adverse
          Consequences arise during the survival period of this Agreement,

          nature of, or caused by any disclosure set forth, or omitted from, a
          Disclosure Schedule, which qualifies, or would qualify, any of the
          representations and warranties of the Seller.



     (c)  Indemnification of Seller.
          ------------------------- 

          In the event the Buyer breaches any of its representations,
          warranties, and covenants contained in this Agreement, provided that
          the Seller makes a written claim for indemnification against the

          suffer through and after the date of the claim for indemnification
          (including any Material Adverse Consequences the Seller  may suffer so
          long as such Material Adverse Consequences arise during the survival

          (i)   If any third party shall notify any of Buyer, the Seller or any
                Taiwan Stockholder (each, an "Indemnified Party") with respect
                to any matter (a "Third Party Claim") which may give rise to a
                claim for indemnification against any other Party (the
                "Indemnifying Party"), then the Indemnified Party shall promptly
                notify each Indemnifying Party thereof in writing; provided,
                however, that no delay on the part of the Indemnified Party in
                notifying any Indemnifying Party shall relieve the Indemnifying
                Party from any obligation hereunder unless (and then solely to
                the extent) the Indemnifying Party thereby is prejudiced.

          (ii)  Any Indemnifying Party will have the right to defend the
                Indemnified Party against the Third Party Claim with counsel of
                its choice reasonably satisfactory to the Indemnified Party so

                Party in writing within fifteen (15) days after notice of the
                Third Party Claim; and (B) the Third Party Claim involves only
                money damages and does not seek an injunction or other equitable
                relief.

          (iii) So long as the Indemnifying Party is conducting the defense of
                the Third Party Claim, (A) the Indemnified Party may retain
                separate co-counsel at its sole cost and expense and participate
                in the defense of the Third Party Claim, (B) the Indemnified
                Party will not consent to the entry of any judgment or enter
                into any settlement with respect to the Third Party Claim
                without the prior written consent of the Indemnifying Party (not
                to be withheld unreasonably), and (C) the Indemnifying Party
                will not consent to the entry of any judgment or enter into any
                settlement with respect to the Third Party Claim without the
                prior written consent of the Indemnified Party (not to be
                withheld unreasonably).


     (e)  Buyer's Right of Offset.
          ------------------------

          Anything in this Agreement to the contrary notwithstanding, Buyer may
          withhold and set off against other amounts otherwise due Seller or a
          Taiwan Stockholder

                   LICENSE AND MANAGEMENT SERVICES AGREEMENT
                   -----------------------------------------


     This LICENSE AND MANAGEMENT SERVICES AGREEMENT (hereinafter referred to as
this "License Agreement") is entered into as of the 1st day of August, 1997, by
and between New System Ltd., a Cayman Islands corporation ("Buyer") and Papnet
Far East Ltd., a Taiwan corporation ("Seller").  Capitalized terms not defined
herein have the meanings given them in the Asset Purchase Agreement dated as of
even date herewith (the "Purchase Agreement") between Buyer, Seller and
stockholders of the Seller.

                                    RECITALS
                                    --------
     A.  The Asset Purchase Agreement contemplates that Buyer will purchase the
Assets from Seller and operate the Business after the Closing;

     B.  Buyer and Seller are ready to proceed with the Closing, but one or more
governmental approvals necessary for the operation of the Business as a branch
office of the Buyer after the Closing ("Necessary Approvals") have not yet been
obtained; and

     C.  Buyer and Seller therefore wish to proceed with the Closing, and
transfer title to the Assets to Buyer at the Closing, but simultaneously to
enter into this License Agreement, pursuant to which Seller will operate the
Business for the benefit of Buyer.

                                   AGREEMENT
                                   ---------

     NOW, THEREFORE, in consideration of the mutual covenants herein contained
and other consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:
<PAGE>
 
     1.  License.  Buyer hereby grants to Seller a license to operate the
         -------

this Agreement; provided, however, that this license in no way constitutes a
                --------  -------                                           
transfer of title or ownership of the Assets to Seller, nor a transfer to Seller
of any intellectual property rights of Buyer.  For purposes of operation of the
Business, Buyer grants to Seller a limited license to use during the term of
this License Agreement and solely for the purpose of Seller's operation of the

     b.  To manage the Business for the benefit of Buyer, in accordance with the
     instructions and policies of Buyer, including, but not limited to,
     employment of a staff sufficient to operate the Business consistent with

     Buyer, and to maintain and operate the Business in such additional or
     modified manner as Buyer may direct from time to time;

     c.  To distribute revenue of the Business to Buyer in such amounts as Buyer
     may direct from time to time;

                                      -2-

     to be incurred by the Business, in such amounts as Buyer may direct from
     time to time;

     practice prior to the acquisition of the Assets by Buyer and in such
     additional or modified manner as Buyer may direct from time to time;

     f.  To render to Buyer, monthly and as of the date of termination of this
     Agreement, an accounting and report which includes all information
     requested by Buyer and in such form as requested by Buyer;

     g.  To grant full access to Buyer to inspect the Assets or records of the
     Business at any time and to permit Buyer to discuss any and all affairs of
     the Business with directors, officers, employees and agents of the Seller;

     desirable to carry out the License Purpose.

     3.  Limitations.  Seller shall not engage in any activities beyond those

necessary or desirable for carrying out the License Purpose, shall not retain
cash in excess of amounts deemed reasonably necessary by Buyer to satisfy the
operating expenses referred to in clause 2 above, and shall at all times act
solely for the benefit of Buyer.

     4.  Duties of Buyer.  Buyer shall allocate a portion of the revenues of the
         ---------------                                                        
Business for payment of employees of the Business and for expenses incurred in
the Ordinary Course of Business, and, so long as Seller operates and maintains
the Business in accordance with clause 2 above, Buyer shall reimburse Seller for

the Business, provided, however, Buyer may modify such allocations
              --------  -------                                    

                                      -3-

license or management fee hereunder.  The consideration paid by Buyer to Seller
at the Closing shall constitute full payment for Seller's management services
hereunder and as manager under any long-term management agreement entered into
pursuant to Section 5(b) below.

     6.  Termination.
         ----------- 
     (a) This License Agreement shall terminate on the date that written notice

Termination Date, possession of all Assets of the Business as of the Termination
Date shall be relinquished to or at the direction of Buyer.  Seller hereby
appoints Buyer as its attorney-in-fact for purposes of executing any document,
or taking any action, necessary or desirable to effect or expedite such
transfer.  This appointment is irrevocable and coupled with an interest, the
adequacy and sufficiency of which is expressly acknowledged by the Buyer and the
Seller.

automatically convert into a long-term management agreement containing the terms
contained in this License Agreement and such additional terms as may be
specified in writing with respect to additional specific management duties to be
performed by Seller, and additional specific limitations on Seller's management
power. If this License Agreement converts into a long-term management agreement,

management agreement. Notwithstanding the foregoing, if Necessary Approvals are

in Taiwan, Buyer may, at its sole discretion, direct Seller to sell, transfer,
liquidate or dispose of the Assets, in whole or in part, and any and all
additional or other property obtained, received, purchased or otherwise accrued
to the Business since the Closing. Any and all of the proceeds and/or
consideration received from such disposition shall be the property of the Buyer

any reason.

its affiliates for any and all claims, expenses or other losses (including
attorneys' fees) arising out of any negligent or willful mismanagement of the
operation of the Business or any breach of this License Agreement from the date
of this License Agreement through and including the Termination Date.  This
indemnification provision shall survive the Termination Date.

received prior to the Closing or receives pursuant to  this License Agreement.
This confidentiality provision shall survive the Termination Date.

     9.  Amendment.  This License Agreement may be amended only by a writing
         ---------

this Third Agreement.

prosecution of such action.  In the event that NSI fails to take action with
respect to such infringement within a reasonable time after notice of
infringement, PFEL shall have the right to bring any appropriate suit or action

8.   Indemnification.


     8.1    Indemnification.  PFEL or NSI, as the case may be (the "Indemnifying
Party"), shall, at its sole cost and expense, indemnify and hold NSI or PFEL and
their respective directors, officers, employees, agents, representatives and
affiliates (each, an "Indemnified Party") harmless with respect to any
liabilities, damages, loses, costs and expenses, including reasonable attorney's
fees (any or all of the foregoing being hereinafter referred to as a "Loss"),
insofar as such Loss arises out of or is based upon (i) a misrepresentation or
breach (or alleged misrepresentation or breach) by the Indemnifying Party of its
warranties, covenants and agreements contained herein or (ii) a claim that the
PAPNET System or the PAPNET Service, as the case may be, as used within the
scope of this Third Agreement, infringes or violates any proprietary rights of
any third party.

     8.2    Notice of claim; defense.  No claim for indemnification hereunder
shall be valid unless notice of the matter which may give rise to such claim is
promptly provided to the Indemnifying Party in writing.  The Indemnifying Party
shall have the exclusive right to defend against any claim and control such
defense.  The Indemnified Party shall cooperate with the Indemnifying Party in
defending against such claim.  In no event shall the Indemnified Party settle
any such claim, lawsuit or proceeding without the Indemnifying Party's prior
written approval.

     8.3    Infringement.  If, as a result of any such claim of infringement,
PFEL or NSI is permanently enjoined from selling the PAPNET Service or using the
PAPNET System, as the case may be, by a final, nonappealable decree, of a court
of competent jurisdiction, NSI at its sole option and expense, may procure for
PFEL the right to continue to sell the PAPNET Service or use the PAPNET System
that is subject to such decree or may replace or modify the PAPNET System or
PAPNET Service so that the PAPNET Service or PAPNET System is non-infringing.
The foregoing states the entire liability of PFEL or NSI, as the case may be, to
the other with respect to infringement of any proprietary rights of any third
party, and PFEL and NSI hereby expressly waive any other such liabilities that
each may have against the other and its directors, officers, employees, agents,
representatives and affiliates.

                              SUBLICENSE AGREEMENT


     This SUBLICENSE, made this 30th day of September, 1997, (This "Sublicense
Agreement") by and between NSI Asia Pacific Ltd., a Cayman Islands corporation
("NSI-APL"), and PAPNET (Far East) Ltd., a Cayman Islands corporation ("PFEL").

     WHEREAS, NSI-APL is a wholly owned subsidiary of Neuromedical Systems,
Inc., a Delaware corporation ("NSI");

     WHEREAS, NSI has designed, developed and produces the PAPNET Testing System
("PAPNET" or "PAPNET Testing"), which is a semi-automated system for the review
of conventionally prepared cytological specimen slides ("Slides");

     WHEREAS, PAPNET consists of a scanning system (the "Scanner"), which
processes Slides and stores digital images of certain portions of such Slides on
a DAT tape or other digital media ("PAPNET Images"), and a proprietary review
station (the "Review Station"), which, among other things, permits a NSI-trained
cytotechnologist to review the images stored on the DAT tape or other digital
media;

     WHEREAS, NSI markets and sells PAPNET Testing as a service, by which end-
user laboratories submit Slides to one of NSI's central facilities for
processing on a Scanner, and NSI returns such Slides and related DAT tape or
other digital media containing PAPNET Images to such laboratories so that NSI-
trained cytotechnologists employed by such laboratories may review the Slides
and the related PAPNET Images using a licensed or leased Review Station
(collectively referred to as the "PAPNET Service");

     WHEREAS, NSI and PFEL are parties to an agreement dated July 13, 1993
providing for, among other things, the representation of NSI in certain markets
by PFEL and the provision of the PAPNET Service to PFEL as an end-user
laboratory (the "First Agreement");

     WHEREAS, NSI and PFEL are parties to an agreement dated May 27, 1994,
amending and restating the First Agreement, and providing for, among other
things, the representation of NSI in certain markets by PFEL and the provision
of the PAPNET Service to PFEL as an end-user laboratory (the "Second
Agreement");

     WHEREAS, NSI-APL has acquired as of June 1, 1997 all of the issued and
outstanding stock of New System International Ltd., a Hong Kong corporation,
previously a wholly owned subsidiary of PFEL, and under the terms and conditions
of the Royalty Agreement Term Sheet, dated as of June 1, 1997 (the "Royalty
Agreement"), executed in connection with such acquisition, NSI and PFEL have
agreed to renegotiate the Second Agreement in accordance with the terms and
conditions set forth therein;

                                      -2-
<PAGE>
 
     WHEREAS, NSI and PFEL have executed as even date herewith an Amended and
Restated Representation Agreement (the "Third Agreement") in accordance with the
terms and conditions set forth in the Royalty Agreement, which supersedes and
replaces the Second Agreement;

     WHEREAS, subject to the terms and conditions of the Third Agreement, NSI
has granted to PFEL a non-exclusive right and license to market, sell and
distribute the PAPNET Service (the "Representation Rights") in Hong Kong, Taiwan
and the People's Republic of China (the "Territory") for a term of fifteen (15)
years;

     WHEREAS, PFEL now desires to assign and sublicense its Representation
Rights for the Territory to NSI-APL, and NSI-APL desires to acquire such
Representation Rights for the Territory.

     NOW, THEREFORE, in consideration of the mutual promises and upon the terms
and subject to the conditions set forth herein, the parties agree as follows:

1.  Assignment of Representation and Marketing Rights.


     1.1    Representation Rights.  Upon the terms and subject to the conditions
of this Sublicense Agreement, PFEL hereby assigns exclusively to NSI-APL during
the Term hereof (as defined in Section 10 herein) any and all of PFEL's
Representation Rights with respect to the PAPNET Service in the Territory to the
full extent granted by NSI to PFEL pursuant to the Third Agreement.

     1.2  Intellectual Property.  PFEL hereby assigns to NSI-APL any and all of
its non-exclusive intellectual property rights, for the limited purpose of NSI-
APL's marketing and sale of the PAPNET(R) Service, the copyrights, trademarks
and trade names used by NSI to identify PAPNET(R) or the PAPNET Service in
accordance with such written specifications as NSI may from time to time make
available to NSI-APL.  NSI-APL agrees to comply with NSI's prevailing policies
regarding use of NSI's copyrights, trademarks and trade names used by NSI's
distributors and representatives, as such policies may be amended from time to
time.   NSI-APL shall not use NSI's copyrights, trademarks or trade names in a
disparaging manner.  Except as authorized in this Section 1.2,  NSI-APL shall
not otherwise use NSI's copyrights, trademarks or trade names without the prior
written approval of NSI.   NSI-APL shall not take any action which is
inconsistent with NSI's ownership of its copyrights, trademarks and trade names.
NSI agrees to include correct trademark, trade name, copyright, trade secrets
and patent notices for the PAPNET System and the PAPNET Service on all materials
and equipment where appropriate.   NSI-APL shall not remove, alter, cover,
obfuscate or otherwise deface any NSI trademark, trade name, patent, trade
secret or copyright notice on the PAPNET System or any part thereof or any
promotion or advertising material used in conjunction with or for the PAPNET
System or the PAPNET Service.

                                      -3-
<PAGE>
 
     1.3    Nature of appointment.  Nothing contained in this Sublicense
Agreement shall (i) prohibit NSI from making, using, licensing, distributing,
selling or granting any other rights in and to PAPNET in the Territory, or (ii)
operate to grant  NSI-APL any rights in or to any product or service offered by
NSI or PFEL other than its rights expressly provided by this Sublicense
Agreement.

     1.4    Field of use restriction.  Except as otherwise contemplated by this
Sublicense Agreement,  NSI-APL shall not market, distribute, sell or license, or
permit any third party to market, distribute, sell or license, the PAPNET
Service to any third party located outside of the NSI-APL Territory other than
as permitted by NSI.   NSI-APL shall not, or shall not permit any third party
to, encourage uses of PAPNET other than as permitted by NSI.

     1.5    Regulatory approval.   NSI-APL shall not market the PAPNET Service
in a particular jurisdiction unless and until all regulatory approvals, licenses
and permits required by such jurisdiction or any court of competent
jurisdiction, governmental body or regulatory agency (a "Governmental Body"), if
any, have been obtained.   NSI-APL, at its sole cost and expense, shall prepare
and submit any and all appropriate applications, data and other information
required by such jurisdiction or Governmental Body to obtain all regulatory
approvals, licenses and permits in such jurisdictions.  NSI shall assist NSI-APL
in filing all required documents with, and in obtaining any necessary approvals,
permits or licenses from, any applicable Governmental Body.

     1.6    Governmental restrictions.  In the event that any Governmental Body
restricts or prohibits the marketing, distribution, provision or licensing of
the PAPNET Service or PAPNET, NSI-APL's rights hereunder shall be subject to and
limited by any such restriction or prohibition without liability to NSI or PFEL
of any type or nature except as expressly provided herein to the contrary.

     1.7    Marketing.   NSI-APL hereby expressly assumes PFEL's marketing
obligations under the Third Agreement, and, at its expense will develop and
implement a comprehensive marketing and sales program to promote successfully
the PAPNET Service in the Territory.  NSI-APL will develop, on an annual basis,
market plans for each major segment of the Territory.  These plans will be
subject to review by NSI.  Each plan will include an outline of NSI-APL's
strategic objectives for the marketing of PAPNET in such Territory, as well as
the specific steps NSI-APL proposes to execute.

2.   Consideration.


     2.1  Royalties for Sales in the Territory.  In consideration of the
Representation Rights assigned hereunder, NSI-APL will pay PFEL a royalty
expressed as a specified percentage of NSI-APL's consolidated revenues derived
from PAPNET(R) Testing System Slides which originate in the Territory (the "Base
Consolidated Revenue"), provided, however, that the Base Consolidated Revenue
                        ------------------                                   
shall not include revenues derived from the processing of Slides within the
Territory with respect to Slides which originate from

                                      -4-
<PAGE>
 
geographic areas outside the Territory (for example, Slides originating in
Australia and processed in the NSI Hong Kong scanning facility shall not be
included in the calculation of Base Consolidated Revenue).  The "specified
percentage" referred to in the first sentence of this Section 2.1 will be 4% of
Base Consolidated Revenue per year during the first four years until the fourth
anniversary of the date hereof, and 3% of Base Consolidated Revenue per year for
each of the following eleven (11) years after the fourth anniversary of the date
hereof (collectively, the "Royalties"), in each case as set forth on the
attached Annex A.  Notwithstanding the foregoing provisions of this Section 2.1,
any Royalties payable from the consolidated revenues from the Territory, shall
include revenues originating in Taiwan only from and after the closing of the
purchase of substantially all of the assets of  New System Taiwan Ltd. by NSI-
APL (or a duly delegated affiliate).

     2.2    Timing and manner of payment of Royalties.  Royalties will be paid
by NSI-APL to PFEL within fifteen (15) days of the last day of the calendar
quarter in which the applicable revenues are actually received by NSI-APL.  Such
payment of Royalties shall be accompanied by a statement setting forth the
calculation thereof.  Any other provision of this Sublicense Agreement
notwithstanding, PFEL shall not be entitled to receive any Royalties with
respect to which NSI-APL  has not actually received payment of the related
revenues.

     2.3    Right to verify the calculation of Royalties.  NSI-APL will maintain
records and bank statements for the purpose of calculating Base Consolidated
Revenues received by NSI-APL from clients in the Territory.  PFEL will have the
right to inspect such records and NSI-APL will provide upon request such other
information as may be reasonably requested by PFEL to confirm the calculation of
the Royalties paid by NSI-APL to PFEL pursuant to this Sublicense Agreement.

3.   Representations and Warranties of NSI-APL.


     NSI-APL hereby represents and warrants to PFEL as follows:

     3.1    Organization.  NSI-APL is a corporation duly organized, validly
existing and in good standing under the laws of Cayman Islands.  NSI-APL has the

and/or any delegation to NSI-APL of the duties required by NSI under the Third
Agreement.  NSI further covenants, and shall cause NSI-APL and their respective
direct and/or indirect subsidiaries to covenant, that PFEL shall receive
substantially the same consideration as it would otherwise receive under this
Sublicense for use of the PAPNET(R) Testing System in any part of the Territory
in the event that NSI or any of its subsidiaries assigns, transfers or
sublicenses any other NSI marketing and/or sales rights to any third party for
use of the PAPNET(R) Testing System in any part of the Territory.

     5.2  Business Practice.   PFEL shall not solicit or take any action that is

System or the PAPNET Service as developed and designed will met any requirements
of or will perform error free or in conformance with the needs or requirements
of NSI-APL or any NSI-APL customer.

                                      -7-

     6.2  Limitation of liability.  Except as provided in Section 8 herein, PFEL
and NSI-APL, as the case may be, shall have no liability with respect to their
respective obligations under this Sublicense Agreement or otherwise for
indirect, special, incidental, consequential, punitive or exemplary damages,
whether in contract, in tort or otherwise, including, but not limited to, loss
of use, revenue or profit, even if  PFEL or NSI-APL, as the case may be, has
been advised of the possibility of such damages, provided, however, that NSI-APL
agrees to indemnify and hold PFEL free and harmless from and against any
liabilities, damages, losses, costs and expenses, including reasonable
attorney's fees incurred by PFEL due to the negligence of NSI-APL in handling
and scanning of Pap smear slides.  In no event shall PFEL's or NSI-APL's
liability, as the case may be, for any reason and upon any cause of action
arising from or relating to this Sublicense Agreement exceed the gross revenues
derived by PFEL or NSI-APL, as the case may be, from this Sublicense Agreement
for the twelve (12) month period immediately preceding the date such cause of
action was commenced; provided, that nothing herein shall be construed to limit
injunctive relief as may be ordered by any court or arbitrator.

7.   Ownership and Intellectual Property Protection.


     7.1    Ownership of PAPNET System.  NSI-APL acknowledges and agrees that
NSI is the sole and exclusive owner of all current and future worldwide patents
and patent rights, copyrights, trademarks, trade names, trade secrets, know-how,
utility models and other intellectual property rights (including without
limitation, all applications and registrations with respect thereto) in and to
the PAPNET System or the PAPNET Service (the "Intellectual Property") embodied
in the PAPNET System, all information, materials, clinical and test data reports
and filings produced in connection with any required regulatory approvals,
permits and licenses, and all information, reports, specifications, source code,
object code, documentation, diagrams, flow charts and any other tangible or
intangible materials of any type whatsoever relating to the PAPNET System and
derived or produced by any parties (collectively the "Proprietary Materials").
No provision contained in this Sublicense Agreement shall be construed to
transfer to NSI-APL any title or ownership interest in the Proprietary Materials
or any Intellectual Property embodied in  the PAPNET System or the PAPNET
Service.  NSI-APL hereby irrevocably assigns, transfers and quitclaims to NSI
all rights, title and interest NSI-APL may at any time be deemed to have in and
to the PAPNET System and all associated Intellectual Property and Proprietary
Material thereof.

     7.2    Scope of use.  NSI-APL shall not, and shall not permit any third
party to, (a) modify or alter, create or attempt to create, by reverse
engineering or otherwise, translate or decompile, translate or transfer, or
otherwise attempt to derive the source code, structure or algorithms of, the
PAPNET System or any part thereof, (b) use or adapt the PAPNET System or any
part thereof in any way, including using or adapting the PAPNET System or any
part thereof otherwise than in connection with the marketing or sale of the
PAPNET Service, (c) use the PAPNET System or any part thereof to create a
derivative work of the PAPNET System, or (d) rent, lease or otherwise provide
temporary access to the PAPNET System or any part thereof.  Unless

                                      -8-
<PAGE>
 
otherwise agreed to, in the event that NSI, in its sole discretion, provides any
modification, upgrades or enhancements to the PAPNET System, such modifications
shall become a part of, and subject to, this Sublicense Agreement.


     7.3    Control of Intellectual Property protection.  NSI shall at all times
retain the sole and exclusive right to pursue, secure, maintain, protect and
enforce its Intellectual Property in and to, or arising out of or related to,
the PAPNET System.

     7.4    PAPNET System name.  NSI shall have the right in its sole discretion
to select and include any trademark or trade name to identify the PAPNET System.

     7.5    Protection of Intellectual Property.  NSI-APL shall use its best
efforts, and shall cause clients to use their best efforts, to protect and
maintain the protection of the Intellectual Property in and to the PAPNET System
or the PAPNET Service.  Upon NSI's request, NSI-APL shall, at NSI's sole cost
and expense, assist NSI-APL in securing, maintaining and enforcing NSI's
Intellectual Property in and to the PAPNET System or the PAPNET Service
including, but not limited to, undertaking any and all necessary and appropriate
actions in accordance with NSI's request.

     7.6    Notice of infringement.  NSI-APL shall promptly notify, and shall
require clients to notify, NSI of any infringement of any Intellectual Property
of NSI with respect to the PAPNET System or the PAPNET Service.  Upon reasonable
notice of infringement, NSI shall have the right, but not the obligation, to
bring any suit or action for infringement of its Intellectual Property at its
own expense.  NSI-APL shall, if requested by NSI, actively assist in the
prosecution of such action.  In the event that NSI fails to take action with
respect to such infringement within a reasonable time after notice of
infringement, NSI-APL shall have the right to bring any appropriate suit or
action against the infringer at NSI-APL expense.  In the event NSI-APL brings
and prevails in such infringement action, any amount recovered from the
infringer, whether by judgment, award, decree or settlement shall firstly be
applied to pay for all losses and damages suffered by NSI-APL together with all
reasonable legal costs and expenses incurred in such action, any balance
thereafter be divided equally between NSI-APL and NSI.

8.   Indemnification.


     8.1    Indemnification.  NSI-APL or PFEL, as the case may be (the
"Indemnifying Party"), shall, at its sole cost and expense, indemnify and hold
NSI-APL or PFEL and their respective directors, officers, employees, agents,
representatives and affiliates (each, an "Indemnified Party") harmless with
respect to any liabilities, damages, loses, costs and expenses, including
reasonable attorney's fees (any or all of the foregoing being hereinafter
referred to as a "Loss"), insofar as such Loss arises out of or is based upon:
(i) a misrepresentation or breach (or alleged misrepresentation or breach) by
the Indemnifying Party of its warranties, covenants and agreements contained
herein, or (ii) a claim that the PAPNET System or the PAPNET Service, as the
case may be, as used

                                      -9-
<PAGE>
 
within the scope of this Sublicense Agreement, infringes or violates any
proprietary rights of any third party.

     8.2    Notice of claim; defense.  No claim for indemnification hereunder
shall be valid unless notice of the matter which may give rise to such claim is
promptly provided to the Indemnifying Party in writing.  The Indemnifying Party
shall have the exclusive right to defend against any claim and control such
defense.  The Indemnified Party shall cooperate with the Indemnifying Party in
defending against such claim.  In no event shall the Indemnified Party settle
any such claim, lawsuit or proceeding without the Indemnifying Party's prior
written approval.

     8.3  Infringement.  If, as a result of any such claim of infringement, PFEL
or NSI-APL is permanently enjoined from selling the PAPNET Service or using the
PAPNET(R) System, as the case may be, by a final, nonappealable decree, of a
court of competent jurisdiction, (i) NSI-APL at its sole option and expense, may
procure from NSI the right to continue to sell the PAPNET Service or use the
PAPNET System that is subject to such decree or may replace or modify the PAPNET
System or PAPNET Service so that the PAPNET Service or PAPNET System is non-
infringing, (ii) NSI-APL may terminate this Sublicense Agreement with respect to
the PAPNET Service or PAPNET(R) System, as the case may be, that is subject to
such decree, or (iii) if PFEL is enjoined from marketing and distributing the
PAPNET Service, NSI-APL may terminate this Sublicense Agreement in accordance
with Section 10 hereof.  The foregoing states the entire liability of PFEL or
NSI-APL, as the case may be, to the other with respect to infringement of any
proprietary rights of any third party, and PFEL and NSI-APL hereby expressly
waive any other such liabilities that each may have against the other and its
directors, officers, employees, agents, representatives and affiliates.

9.   Confidentiality.


     9.1  Confidentiality.  During the term of this Sublicense Agreement and
thereafter, each of NSI-APL and PFEL shall keep strictly confidential all
proprietary information, sales statistics, customer lists, customer account
information, this Sublicense Agreement and its terms and other confidential
information concerning the business of the other party, however obtained, and
shall not reveal or disclose the same to any person or entity without the prior
written consent of the other party; provided, however, that either party may
                                    --------  -------                       
disclose such information pursuant to a subpoena, order, statute, rule or other
legal requirement promulgated or imposed by a court or by a judicial, regulatory
or legislative body or agency in which such party is involved; and provided,

party discloses such confidential information in accordance with the previous
sentence, such party shall immediately notify the other party.

10.    Term.


     10.1    Term. The term of this Sublicense Agreement shall commence on the
date first set forth above and terminate at the end of the fifteenth (15th) year
from the date of execution hereof (the "Term") unless terminated on an earlier
date as provided below in this Section 10.

     10.2    Termination Fee.  In the event of cessation of business related to
the Representation Rights by NSI-APL or its affiliates in the entirety of the
Territory prior to the end of the Term, a termination fee shall be due and
payable to PFEL by NSI-APL in an amount equal to US$800,000 (the "Termination
Fee"), provided, however, that payment of the Termination Fee shall be
       --------- -------                                              
subordinate to all other creditors of NSI-APL, including, but limited to, any
interest due with regard to any indebtedness thereto, and further provided that
                                                          ------- --------     
the Termination Fee shall diminish in amount equal to the aggregate amount of
Royalties received by PFEL (for example, if the business of NSI-APL terminated
at the end of year one, and as of such date PFEL had received an aggregate of
US$200,000 in royalties from NSI-APL, the Termination Fee would be reduced by
US$200,000).

     10.3    Purchase Option.  During the period commencing four years after
execution of this Sublicense Agreement, and ending eight years after such
execution, as set forth on the attached Annex A, PFEL may, at its option,
require NSI-APL to purchase the entirety of PFEL's interest as a party to the
Third Agreement (including any and all rights obtained by assignment or
sublicense thereof) for an aggregate price equal to five times the trailing
year's Royalty (the "Purchase Option" and the price paid pursuant thereto, the
"Purchase Price").  The Purchase Price may be payable at the option of NSI-APL
in either cash or in NSI common stock, par value $.0001 per share ("Common
Stock").  For purposes of this provision, "trailing year" shall mean the most
recent twelve (12) month period measured at the end of the most recently
completed calendar quarter (for example, if PFEL exercises the Purchase Option
at the end of the second (2nd)calendar quarter during year six of this
Sublicense Agreement, the Purchase Price would be five (5) times the amount of
Royalties recorded as paid or payable during the twelve (12) month period
immediately preceding the end of the second (2nd) calendar quarter of year six
(6)).  If the Purchase Price is paid in NSI Common Stock, (i) the value of the
NSI Common Stock will be determined based on the average closing price of the
Common Stock on the most recent thirty (30) calendar days immediately prior to
the exercise date of such Purchase Option; (ii) PFEL shall execute a
Subscription Agreement substantially in the form set forth in the attached Annex
B and (iii) PFEL shall execute a Registration Rights agreement substantially  in
the form set forth in the attached Annex C and NSI shall provide registration
rights with respect to such NSI Common Stock in accordance with the terms
thereunder.  The Termination Fee shall not be due or payable if the Purchase
Option is exercised by PFEL.  Exercise and consummation of the Purchase Option
shall terminate this Sublicense Agreement.  For purposes of clarity, this
Purchase Option may only be exercised by PFEL and not by NSI or NSI-APL.

     10.4    Termination.

     (a)  This Sublicense Agreement shall be terminated prior to the end of the
Term upon performance by NSI-APL of its duties and obligations in accordance
with the terms of paragraphs 10.2 or 10.3.

     (b) Except as otherwise provided in this Sublicense Agreement, this
Sublicense Agreement may be terminated by NSI-APL without notice to PFEL or
further action on the part of NSI-APL, upon the occurrence of any of the
following events: (i) the liquidation, dissolution, winding up or other
termination, suspension, discontinuation or failure of the business of PFEL;
(ii) the insolvency of or admission by PFEL of its failure to pay debts as they
mature, the making by PFEL of an assignment for the benefit of its creditors or
the filing by PFEL of a petition in bankruptcy, the seeking by PFEL of
reorganization or arrangement with creditors or PFEL otherwise taking advantage
of any insolvency, readjustment of debt, dissolution or liquidation law, or any
similar law, of any jurisdiction whether now or hereafter in effect; (iii) upon
PFEL being declared bankrupt or wound up by any court of competent jurisdiction;
(iv) if PFEL is enjoined at any time from marketing and distributing the
PAPNET(R) Service, or assigning and/or sublicensing its rights under the Third
Agreement or delegating its duties and obligations undertaken thereby; (v) any
assignment, sublicense, delegation, or any other transfer, in whole or in part,
of the Third Agreement by PFEL without the express prior written consent of NSI;
or (vi) upon termination of the Third Agreement by reason of the default of
PFEL.

     (c) Except as otherwise provided in this Sublicense Agreement, this
Sublicense Agreement may be terminated by PFEL without notice to NSI-APL OR
further action on the part of PFEL, upon the occurrence of any of the following
events (each, an "NSI-APL Termination Event"): (i) The liquidation, dissolution,
winding up or other termination, suspension, discontinuation or failure of the
business of NSI-APL or its efforts to market the PAPNET Service; (ii) the
insolvency of or admission by NSI-APL of its failure to pay debts as they
mature, the making by NSI-APL of an assignment for the benefit of its creditors
or the filing by NSI-APL of a petition in bankruptcy, the seeking by NSI-APL of
reorganization or arrangement with creditors or NSI-APL otherwise taking
advantage of any insolvency, readjustment of debt, dissolution or liquidation
law of any jurisdiction whether now or hereafter in effect; or (iii) the filing
of any bankruptcy petition against NSI-APL, which petition is not dismissed
within sixty (60) days.  Termination of this sublicense agreement due to an nsi-
apl termination event shall not absolve or excuse performance of NSI-APL'S
duties and obligations in accordance with SECTIONS 10.2 OR 10.3.

     (D)  Except as otherwise provided herein, the termination of this
Sublicense AGREEMENT (whether pursuant to Section 10.4 or upon the expiration of
the Term) or any part hereof by either party shall not relieve either party of
any obligations accruing prior to such termination.  The representations,
warranties, covenants and agreements of NSI and PFEL set forth herein shall
survive any such termination.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements

on the third anniversary of the Commencement Date and on each anniversary
thereafter, the Term shall be automatically extended for an additional period of
one (1) year, unless either party gives written notice to the other at least
ninety (90) days prior thereto that the Term of this Agreement shall not be so
extended, provided, further, however, that the Term may be earlier terminated as
hereinafter provided.

     3.  Duties; Best Efforts; Indemnification.
         ------------------------------------- 

     The Employee shall serve as the President and Chief Executive Officer of
NSI and shall perform and discharge well and faithfully the duties which may
from time to time be prescribed by the Board of Directors of NSI ( the "Board").
During the Term, NSI shall nominate the Employee for election to, and use its
best efforts to cause the Employee to be
<PAGE>
 
elected to the Board.  The Employee shall devote all of his business time,
attention and energies to the business and affairs of NSI, shall use his best
efforts to advance the best interests of NSI and shall not during the Term be
actively engaged in any other business activity, whether or not such business
activity is pursued for gain, profit or other pecuniary advantage.

     Subject to the provisions of NSI's Certificate of Incorporation and Bylaws,
each as amended from time to time, NSI shall indemnify the Employee to the
fullest extent permitted by the General Corporation Law of the State of
Delaware, as amended from time to time, for all amounts (including without
limitation, judgments, fines, settlement payments, expenses and attorney's fees)
incurred or paid by the Employee in connection with any action, suit,
investigation or proceeding arising out of or relating to the performance by the
Employee of services for, or the acting by the Employee as an officer or
employee of, NSI, or any other person or enterprise at NSI's request; provided,
however, that NSI shall not be required to indemnify the Employee against any
liability resulting from conduct which is willful, intentional or grossly
negligent.  NSI shall use its best efforts to obtain and maintain in full force
and effect during the Term directors' and officers' liability insurance policies
providing full and adequate protection to the Employee for his capacities,
provided that the Board shall have no obligation to purchase such insurance if,
in its opinion, coverage is available only on unreasonable terms.

     4.  Compensation and Benefits.
         ------------------------- 

     (a) Base Salary.  NSI shall pay to the Employee a base salary (the "Base
         -----------                                                         
Salary") at a rate of not less than $350,000 per annum, payable in accordance
with NSI's ordinary payroll practices as in effect from time to time during the
Term.  The Board at least annually will review the Base Salary and other
compensation during the Term with a view to the increase thereof based upon the
Employee's performance, the performance of NSI, inflation, then prevailing
industry salary scales and other relevant factors.  Base Salary will not include
any bonus paid to the Employee from time to time.

     (b) Bonus.  In respect of each fiscal year beginning during the Term, the
         -----                                                                
Employee shall have the opportunity to earn a bonus of up to 50% of his annual
Base Salary (the "Bonus") upon the attainment of financial or other performance
goals mutually agreed to by the Employee and the Board not later than 90 days
after the commencement of the applicable fiscal year; provided, however, that
for the 1998 fiscal year, the Employee shall be entitled to receive a Bonus of
$175,000 without regard to performance; provided, further, however, that any
bonus payable in respect of a fiscal year that ends after the Term shall be
prorated based on the portion of the fiscal year that has elapsed during the
Term.  Any bonus payable hereunder shall be paid in accordance with NSI's
practice with respect to the payment of bonuses to its other senior executives.

     (c) Stock Options.  As of the Commencement Date, NSI shall grant the
         -------------                                                   
Employee stock options to acquire (i) an aggregate of 750,000 shares of NSI
common stock (the "Common Stock") at an exercise price equal to the closing
price of the Common Stock on

                                      -2-
<PAGE>
 
the last trading day prior to the Commencement Date; and (ii) an aggregate of
250,000 shares of Common Stock at an exercise price of $10.00 per share.  The
stock options shall become vested and exercisable with respect to 25% of the
aggregate number of shares of Common Stock covered by each stock option as of
the first, second, third and fourth anniversaries of the date of grant and shall
be subject to such other terms and conditions as set forth in the stock option
agreements attached hereto as Exhibits A and B.

     (d) Out-of-Pocket Expenses.  NSI shall promptly pay to the Employee
         ----------------------                                         
the reasonable expenses incurred by him in the performance of his duties
hereunder, including, without limitation, those incurred in connection with
business related travel or entertainment, or, if such expenses are paid directly
by the Employee, shall promptly reimburse him for such payment, provided that
the Employee properly accounts therefor in accordance with NSI's policy.

     (e) Relocation Expenses.  In accordance with NSI's relocation policy, NSI
         -------------------                                                  
shall reimburse the Employee for up to $75,000 in moving expenses incurred by
him in his relocation to the Suffern, New York area, closing costs in connection
with the sale of his residence in Phoenix, Arizona and reasonable air travel for
the Employee to and from Phoenix, Arizona.

     (f) Housing Allowance.  NSI shall pay to the Employee a housing allowance
         -----------------                                                    
in the amount of $2,500 per month through June 30, 1998.

     (g) Participation in Benefit Plans.  The Employee shall be entitled to
         ------------------------------                                    
participate in or receive benefits under any pension plan, profit sharing plan,
health and accident plan or any other employee benefit plan or arrangement made
available in the future by NSI to its executives and key management employees,
subject to the terms and conditions applicable to executives and key management
generally.

     (h) Vacation.  The Employee shall be entitled to such paid vacation
         --------                                                       
days in each calendar year as determined by NSI from time to time, but not less
than three (3) weeks in any calendar year, prorated in any calendar year during
which the Employee is employed hereunder for less than an entire year in
accordance with the number of days in such year during which he is so employed.
The Employee shall also be entitled to all paid holidays given by NSI to its
executives and key management employees.  Such vacation and holiday allowance
shall otherwise be subject to the policies and practices of NSI.

     5.  Termination.
         ----------- 

        The Employee's employment hereunder shall be terminated upon the
Employee's death and may be terminated as follows:

        (a) By NSI for "Cause."  A termination for Cause is a termination upon
a finding by NSI that the Employee has (i) intentionally failed to perform
reasonably assigned duties, (ii) engaged in dishonest or willful misconduct in
the performance of his duties,

                                      -3-
<PAGE>
 
(iii) engaged in a transaction in connection with the performance of his duties
to the Company or any of its Subsidiaries thereof which transaction is adverse
to the interests of the Company or any of its Subsidiaries and which is engaged
in for personal profit by the Employee or (iv) willfully violated any law, rule
or regulation in connection with the performance of his duties (other than
traffic violations or similar offenses).

          (b) By NSI due to the Employee's "Disability."  For purposes of this
Agreement a termination for Disability shall occur (i) upon the thirtieth (30th)
day after the issuance of  a written termination notice to the Employee in the
event that the Employee shall have become so incapacitated as to be unable to
resume, within the ensuing six (6) months, his employment hereunder by reason of
physical or mental illness or injury, or (ii) upon the issuance of a written
termination notice after the Employee has been unable to substantially perform
his duties hereunder for three (3) consecutive months by reason of any physical
or mental illness.

          (c)  By NSI without Cause.

          6.  Compensation Upon Termination.
              ----------------------------- 

          (a) In the event of the termination of the Employee's employment as a
result of the Employee's death, NSI shall (i) pay to the Employee's estate his
Base Salary through the date of his death, and (ii) for the shorter of one (1)
year following his death or the balance of the Term (as if such termination had
not occurred) provide continuation coverage to the members of the Employee's
family under all Blue Cross/Blue Shield, major medical and other health,
accident, life or other disability plans and programs in which such family
members participated immediately prior to his death.

          (b) In the event of the termination of the Employee's employment by
NSI for Cause or by the Employee for any reason NSI shall pay to the Employee
his Base Salary through the date of his termination, and the Employee's
entitlement to any other compensation or benefits shall be determined in
accordance with NSI's plans, policies and practices as in effect from time to
time.

          (c) In the event of the termination of the Employee's employment by
NSI due to Disability, NSI shall pay to the Employee his Base Salary through the
date of his termination.  In addition, for the shorter of one (1) year following
any such termination or the balance of the Term (as if such termination had not
occurred), NSI shall (i) continue to pay the Employee the Base Salary in effect
at the time of such termination less the amount, if any, then payable to the
Employee under any disability benefits of NSI and (ii) provide the Employee
continuation coverage under all Blue Cross/Blue Shield, major medical and other
health, accident, life or other disability plans and programs in which the
Employee participated immediately prior to such termination, to the extent that
such benefits continue to be made available to active employees of NSI.

                                      -4-
<PAGE>
 
          (d) In the event that the Employee's employment is terminated by NSI
other than for Cause or Disability, for a period of eighteen (18) months
following any such termination, NSI shall (i) continue to pay the Employee the
Base Salary in effect at the time of such termination and (ii) provide
continuation coverage under all Blue Cross/Blue Shield, accident, life or other
disability plans and programs in which the Employee participated immediately
prior to such termination, to the extent such benefits continue to be made
available to active employees of NSI.  The continuation of Base Salary provided
for in clause (i) of the preceding sentence shall not be reduced by any
compensation or other income that the Employee may earn from subsequent
employment or otherwise.

          (e) The continuation coverage under any Blue Cross/Blue Shield, major
medical and other health, accident, life or other disability plans and programs
for the periods provided in Sections 6(a), 6(c) and 6(d) shall be provided (i)
at the expense of NSI and (ii) in satisfaction of NSI's obligation under Section
4980B of the Code (and any similar state law) with respect to the period of time
such benefits are continued hereunder.  Notwithstanding anything to the contrary
contained herein, NSI's obligation to provide such continuation coverage under
Sections 6(a), 6(c) or 6(d) shall cease immediately upon the date any covered
individual becomes eligible for similar benefits under the plans or policies of
another employer.

          (f) This Section 6 sets forth the only obligations of NSI with respect
to the termination of the Employee's employment with NSI and the Employee
acknowledges that upon his termination of employment he shall not be entitled to
any payments or benefits which are not explicitly provided herein.

          7.  Covenant Regarding Inventions and Copyrights.
              -------------------------------------------- 

          The Employee shall disclose promptly to NSI any and all inventions,
discoveries, improvements and patentable or copyrightable works initiated,
conceived or made by him, either alone or in conjunction with others, during the
Term and related to the business or activities of NSI and he assigns all of his
interest therein to NSI or its nominee; whenever requested to do so by NSI, the
Employee shall execute any and all applications, assignments or other
instruments which NSI shall deem necessary to apply for and obtain letters
patent or copyrights of the United States or any foreign country or otherwise
protect NSI's interest therein.  These obligations shall continue beyond the
conclusion of the Term with respect to inventions, discoveries, improvements or
copyrightable works initiated, conceived or made by the Employee during the Term
and shall be binding upon the Employee's assigns, executors, administrators and
other legal representatives.

          8.  Protection of Confidential Information.
              -------------------------------------- 

          The Employee acknowledges that he will be provided with information
about, and his employment by NSI will, throughout the Term, bring him into close
contact with, many confidential affairs of NSI and its subsidiaries, including
proprietary information about costs, profits, markets, sales, products, key
personnel, pricing policies, operational methods,

                                      -5-
<PAGE>
 
technical processes and other business affairs and methods, plans for future
developments and other information not readily available to the public, all of
which are highly confidential and proprietary and all of which were developed by
NSI at great effort and expense.  The Employee further acknowledges that the
services to be performed by him under this Agreement are of a special, unique,
unusual, extraordinary and intellectual character, that the business of NSI will
be conducted throughout the world (the "Territory"), that its products will be
marketed throughout the Territory, that NSI competes and will compete in nearly
all of its business activities with other organizations which are located in
nearly any part of the Territory and that the nature of the relationship of the
Employee with NSI is such that the Employee is capable of competing with NSI
from nearly any location in the Territory.  In recognition of the foregoing, the
Employee covenants and agrees during the Term and thereafter:

          (i) That he will keep secret all confidential matters of NSI and not
copy them or disclose them to anyone outside of NSI, either during or after the
Term, except with NSI's prior written consent or, if during the Term, in the
performance of his duties hereunder, the Employee makes a good faith
determination that it is in the best interest of NSI to disclose such matters;

          (ii) That he will not make use of any of such confidential matters for
his own purposes or the benefit of anyone other than NSI; and

          (iii)  That he will deliver promptly to NSI on termination of this
Agreement, or at any time NSI may so request, all confidential memoranda, notes,
records, reports and other confidential documents (and all copies thereof)
relating to the business of NSI, which he may then possess or have under his
control.

          9.  Restriction on Competition, Interference and Solicitation.
              --------------------------------------------------------- 

          In recognition of the considerations described in Section 8 hereof,
the Employee covenants and agrees that, during the Term and for a period of two
(2) years after the termination of his employment hereunder, the Employee will
not, directly or indirectly, (A) enter into the employ of, or render any
services to, any person, firm or corporation engaged in any business competitive
with the business of NSI in any part of the Territory; (B) engage in any such
business for his account; (C) become interested in any such business as an
individual, partner, shareholder, creditor, director, officer, principal, agent,
employee, trustee, consultant advisor, franchisee or in any other relationship
or capacity; or (D) interfere with NSI's relationship with, or endeavor to
employ or entice away from NSI any person, firm, corporation, governmental
entity or other business organization who or which is or was an employee,
customer or supplier of, or maintained a business relationship with, NSI at any
time (whether before, during or after the Term), or which NSI has solicited or
prepared to solicit; provided, however, that nothing contained in this Section 9
                     --------  -------                                          
shall be deemed to prohibit the Employee from acquiring or holding, solely for
investment, publicly traded securities of any corporation some of the activities
of which are competitive with the business of NSI so

                                      -6-
<PAGE>
 
long as such securities do not, in the aggregate, constitute more than five
percent (5%) of any class or series of outstanding securities of such
corporation.

          10.  Specific Remedies.
               ----------------- 

          For purposes of Sections 7, 8 and 9 of this Agreement, references to
NSI shall include all current and future majority-owned subsidiaries of NSI and
all current and future joint ventures in which NSI may from time to time be
involved.  It is understood by the Employee and NSI that the covenants contained
in this Section 10 and in Sections 7, 8, and 9 hereof are essential elements of
this Agreement and that, but for the agreement of the Employee to comply with
such covenants, NSI would not have agreed to enter into this Agreement.  NSI and
the Employee have independently consulted with their respective counsel and have
been advised concerning the reasonableness and propriety of such covenants with
specific regard to the nature of the business conducted by NSI and the interests
of NSI and its stockholders.  The Employee agrees that the covenants of Sections
7, 8, and 9 are reasonable and valid.  If the Employee commits a breach of any
of the provisions of Sections 7, 8, or 9, such breach shall be deemed to be
grounds for termination for Cause.  In addition, the Employee acknowledges that
NSI may have no adequate remedy at law if he violates any of the terms hereof.
The Employee therefore understands and agrees that NSI shall have (i) the right
to have such provisions specifically enforced by any court having equity
jurisdiction, it being acknowledged and agreed that any such breach will cause
irreparable injury to NSI and that money damages will not provide an adequate
remedy to NSI, and (ii) the right to require the Employee to account for and pay
over to NSI all compensation, profits, monies, accruals, increments and other
benefits (collectively, the "Benefits") derived or received by the Employee as a
result of any transaction constituting a willful breach of any of the provisions
of Sections 7, 8, or 9 and the Employee hereby agrees to account for and pay
over such Benefits to NSI.

          11.  Independence, Severability and Non-Exclusivity.
               ---------------------------------------------- 

          Each of the rights enumerated in Section 10 hereof shall be
independent of the others and shall be in addition to and not in lieu of any
other rights and remedies available to NSI at law or in equity.  If any of the
covenants contained in Sections 7, 8, or 9, or any part of any of them, is
hereafter construed or adjudicated to be invalid or unenforceable, the same
shall not affect the remainder of the covenant or covenants or rights or
remedies which shall be given full effect without regard to the invalid
portions.  The parties intend to and do hereby confer jurisdiction to enforce
the covenants contained in Sections 7, 8, or 9 and the remedies enumerated in
Section 10 upon the federal and state courts of New York sitting in New York
County.  If any of the covenants contained in Sections 7, 8, or 9 is held to be
invalid or unenforceable because of the duration of such provision or the area
covered thereby, the parties agree that the court making such determination
shall have the power to reduce the duration and/or area of such provision and in
its reduced form said provision shall then be enforceable.  No such holding of
invalidity or unenforceability in one jurisdiction shall bar or in any way
affect NSI's right to the relief provided in Section 10 or otherwise in the
courts of

                                      -7-
<PAGE>
 
any other state or jurisdiction within the geographical scope of such covenants
as to breaches of such covenants in such other respective states of
jurisdictions, such covenants being, for this purpose, severable into diverse
and independent covenants.

          12.  Disputes.
               -------- 

          If NSI or the Employee shall dispute any termination of the Employee's
employment hereunder or if a dispute concerning any payment hereunder shall
exist:

          (a) either party shall have the right (but not the obligation), in
addition to all other rights and remedies provided by law, to compel arbitration
of the dispute in the City of New York under the rules of the American
Arbitration Association by giving written notice of arbitration to the other
party within thirty (30) days after notice of such dispute has been received by
the party to whom notice has been given; and

          (b) if such dispute (whether or not submitted to arbitration pursuant
to Section 12(a) hereof) results in a determination that (i) NSI did not have
the right to terminate the Employee's employment under the provisions of this
Agreement or (ii) the position taken by the Employee concerning payments to the
Employee is correct, NSI shall promptly pay, or if theretofore paid by the
Employee, shall promptly reimburse the Employee for, all costs and expenses
(including attorney's fees) reasonably incurred by the Employee in connection
with such dispute.

          13.   Successors; Binding Agreement.
               ------------------------------ 

          This Agreement shall be binding upon and shall inure to the benefit of
NSI, its successors and assigns and NSI shall require any successor or assign to
expressly assume and agree to perform this Agreement in the same manner and to
the same extent that NSI would be required to perform it if no such succession
or assignment had taken place.  "NSI" as used herein shall include any such
successors and assigns to NSI's business and/or assets.  The term "successors
and assigns" as used herein shall mean a corporation or other entity acquiring
or otherwise succeeding to, directly or indirectly, all or substantially all the
stock or assets and business of NSI (including this Agreement) whether by
operation of law or otherwise.
 
          This Agreement and all rights of the Employee hereunder shall inure to
the benefit of, and be enforceable by, the Employee's personal or legal
representatives, executors, administrators, administrators c.t.a., successors,
heirs, distributees, devisees and legatees.  Unless otherwise provided herein,
any amounts payable hereunder after the Employee's death shall be paid in
accordance with the terms of this Agreement to the Employee's estate.

          14.  Notices.
               ------- 

          All notices, consents or other communications required or permitted to
be given by any party hereunder shall be in writing (including telecopy or other
similar writing) and

                                      -8-

                    __________________________

or at such other address or telecopy number (or other similar number) as either
party may from time to time specify to the other.  Any notice, consent or other
communication required or permitted to be given hereunder shall be deemed to
have been given on the date of mailing, personal delivery or telecopy or other
similar means thereof (provided the appropriate answer back is received) and
shall be conclusively presumed to have been received on the second business day
following the date of mailing or, in the case of personal delivery or telecopy

               ----------------------- 

          Employee represents and warrants that his execution of this Agreement

               ------------------------- 

          No term, provision or condition of this Agreement may be modified or
discharged unless such modification or discharge is authorized by the Board and
is agreed to in writing and signed by the Employee.  No waiver by either party
hereto of any breach by the other party hereto of any term, provision or
condition of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or subsequent time.

been no published bid or asked quotations with respect to Shares on such date,
the Fair Market Value shall be the value established by the Board in good faith.
