                                  OUR BUSINESS



    CVC is a worldwide supplier of process equipment used to manufacture
magnetic recording heads for disk drives and advanced semiconductor devices for
computers and communications systems. Our equipment either deposits or removes
thin film layers as steps in the process of manufacturing magnetic recording
heads and semiconductor devices. Our customers include most of the leading
manufacturers of magnetic recording heads for the data storage industry such as
Alps, Fujitsu, IBM, Read-Rite, Seagate Technology, TDK and Yamaha, as well as
manufacturers of semiconductor devices, such as Anadigics, Analog Devices,
Honeywell and M/A-COM.



    The manufacture of magnetic recording heads, which read and write
information onto disk drives, and semiconductor devices requires from tens to
hundreds of processing steps. Both magnetic recording heads and semiconductor
devices are formed by depositing or removing extremely thin, uniform layers of
conducting or insulating films onto surfaces called "substrates" or "wafers."
The need to increase the storage density of disk drives has led to the
development of smaller, more advanced magnetic recording heads with multiple
layers of different materials and surface structures. In order to increase the
performance of semiconductor devices, semiconductor manufacturers are shrinking
the geometries and line widths of integrated circuits, while at the same time
adding multiple layers of insulating or conducting materials. The process of
manufacturing magnetic recording heads and semiconductor devices is constantly
evolving to address the demand for smaller devices with higher performance and
requires advanced process equipment.



    Our principal product, the CONNEXION Cluster Tool system, is designed for
the highly uniform, repetitive steps required for the manufacturing of devices
involving multiple thin film layers and a wide range of materials. The CONNEXION
Cluster Tool system allows our customers to attach up to six process modules to
a central substrate handling platform. This architecture provides a controlled
vacuum environment in which multiple steps are performed without exposing the
substrate to outside contamination. We believe that the CONNEXION Cluster Tool
system is well suited for next generation applications involving deposition of
advanced materials like copper. Since 1993, we have shipped more than 100
CONNEXION Cluster Tool systems, including more than 400 process modules.



    CVC was incorporated in 1990 in connection with its acquisition of CVC
Products, Inc. CVC Products, Inc. was founded in 1934 as the experimental vacuum
processing group of Eastman Kodak. Our executive offices are located at 525 Lee
Road, Rochester, New York, 14606, and our telephone number is (716) 458-2550.

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMMON STOCK IS RISKY. YOU SHOULD CAREFULLY CONSIDER
THE FOLLOWING RISKS, AS WELL AS THE OTHER INFORMATION CONTAINED IN THIS
PROSPECTUS.

WE EXPERIENCE FLUCTUATIONS IN OUR OPERATING RESULTS WHICH MAY ADVERSELY IMPACT
OUR STOCK PRICE.

    Our quarterly operating results have fluctuated significantly in the past,
and we expect this trend to continue. A principal reason is that we derive a
substantial portion of our revenue from the sale of a relatively small number of
systems which typically range in price from approximately $1.0 million to
$4.0 million. As a result, our revenues and results of operations for any one
quarter may be adversely affected by factors relating to the timing of orders
and shipments of these systems. Additional factors which affect our quarterly
operating results include:

    - specific economic conditions in the data storage and semiconductor
      industries

    - cyclical patterns of capital spending by customers

    - modification or cancellation of customer orders

    - continued market acceptance of our systems and our customers' products

    - shipment delays

    - loss of a significant customer

    - increased research and development or marketing costs associated with our
      introduction of new products

    - introduction of new products by our customers

    - our ability to successfully introduce new products on a timely basis

    - changes in our pricing policies or those of our competitors

    - production and quality problems


    - the publication of opinions by industry analysts about us, our products or
      our competitors



    Many of these factors are beyond our control, and our operating results for
any particular quarter may differ materially from our expectations or those of
the market. In addition, our operating results may not be indicative of future
operating results, which may adversely impact the price of our common stock.



YEAR 2000 PROBLEMS OF OUR CUSTOMERS COULD CAUSE THEM TO DELAY PAYMENT FOR
PRODUCTS THAT WE HAVE SHIPPED TO THEM, WHICH COULD CAUSE OUR REVENUES TO
DECREASE.



    Our customers or potential customers may be affected by Year 2000 issues
that may, in part (1) cause a delay in payments for products shipped, (2) cause
customers to expend significant resources on Year 2000 compliance matters,
rather than investing in our products or (3) cause customers to defer placing
orders for our systems in the first quarter of our fiscal 2000 or beyond. These
issues may impact our operating results in the first quarter of fiscal 2000, our
first quarter as a public company.


A SIGNIFICANT AMOUNT OF OUR REVENUES IS RECORDED LATE IN EACH QUARTER. WE MAY BE
UNABLE TO ADJUST SPENDING QUICKLY ENOUGH TO COMPENSATE FOR SHORTFALLS IN
QUARTERLY REVENUES, AND AS A RESULT OUR OPERATING RESULTS COULD BE ADVERSELY
AFFECTED.


    We have historically recorded a significant amount of our revenues for each
quarter late in the quarter, while our expenses have been incurred more evenly
throughout the period. The concentration


                                       4
<PAGE>

of product shipments late in the quarter is primarily due to customer order
patterns and the length of our production cycle. This concentration increases
the risk of shipment delays and, consequently, the risk that quarterly revenue
expectations will not be met. Our revenues for a particular period could be
materially reduced if an anticipated order for even one system is not received
in time to permit shipment during that period. In addition, a significant
portion of our expenses is relatively fixed.



    We also have limited visibility on revenues for future quarterly periods and
face risks of revenue shortfalls due to our limited sales backlog in current
periods. If the number of systems we actually ship, and thus the amount of
revenues we are able to record, late in any particular quarter is below
expectations for any reason, the adverse effect may be magnified by our
inability to adjust spending quickly enough to compensate for the revenue
shortfall.


THE SUCCESS OF OUR BUSINESS DEPENDS ON THE DEMAND FOR PRODUCTS FROM DATA STORAGE
AND SEMICONDUCTOR MANUFACTURERS, WHOSE INDUSTRIES ARE HIGHLY CYCLICAL.

    Our business depends in large part upon the demand for products from data
storage and semiconductor manufacturers. The data storage and semiconductor
industries accounted for the following percentages of our net sales for the
periods indicated:


<TABLE>

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

Semiconductor.........................................        9%            21%             9%
</TABLE>



    The data storage and semiconductor industries have been characterized by
cyclicality. These industries have experienced significant economic downturns at
various times in the last decade, characterized by slowing product demand,
inventory surpluses, accelerated erosion of average selling prices and
production overcapacity. In the recent past, these downturns have materially
reduced demand for the type of capital equipment and process technology that we
offer. In addition, because of (1) our continuing need to invest in research and
development, (2) our substantial capital equipment requirements and (3) our
extensive ongoing customer service and support requirements worldwide, our
ability to reduce expenses in response to any downturn or slowdown in the rate
of capital investment by manufacturers in these industries may be limited.



    In the recent past, the data storage and semiconductor industries have
experienced inventory oversupply and poor operating results. Our business could
be harmed if slowdowns in the rate of capital investment or inventory surpluses
in the data storage and semiconductor industries occur in the future.


OUR REVENUES AND PROFITS MAY DECREASE IF WE LOSE ANY OF OUR MAJOR CUSTOMERS.


    Our customer base is highly concentrated among a limited number of large
customers, primarily because the data storage industry is dominated by a small
number of large companies. In particular, purchases by Seagate Technology, also
our largest stockholder, have historically accounted for a significant portion
of our revenues. The loss of any of these customers, and the loss of Seagate
Technology in particular, could result in a material decrease in our revenues.
The following table sets forth the percentage of our total revenues derived from
sales to our five largest customers, as well as Seagate Technology on a
stand-alone basis, for the periods indicated:

<PAGE>
We anticipate that our revenue will continue to depend on a limited number of
major customers, although the companies considered to be major customers and the
percentage of our revenue represented by each major customer may vary from
quarter to quarter.


    We generally do not have long-term purchase agreements with our customers
and do not have any written agreements that require customers to purchase fixed
minimum quantities of our products. Our sales to specific customers tend to vary
significantly from year to year depending upon our customers' budgets for
capital expenditures and new product introductions. The loss of, or reduced
demand for products or related services from, any of our major customers could
harm our business. If any of these large manufacturers discontinues its
relationship with us or suffers economic downturns, our operating results could
suffer.



IF WE DO NOT RESPOND EFFECTIVELY AND ON A TIMELY BASIS TO RAPID TECHNOLOGICAL
CHANGE, OUR ABILITY TO ATTRACT AND MAINTAIN CUSTOMERS COULD BE DIMINISHED.



    The data storage and semiconductor manufacturing industries are subject to
rapid technological change and new product introductions and enhancements, as
well as evolving industry standards. Our ability to remain competitive will
depend in part upon our ability to develop new and enhanced systems at
competitive prices in a timely and cost-effective manner and to accurately
predict technology transitions. In addition, new product introductions or
enhancements by our competitors could cause a decline in sales or loss of market
acceptance of our existing products. Increased competitive pressure could also
lead to intensified price competition, resulting in lower margins, which could
adversely impact our business.


    Because new product development commitments must be made well in advance of
sales, new product decisions must anticipate both the future demand for the
products under development and the equipment required to produce such products.
We cannot be certain that we will be successful in developing, manufacturing and
marketing new products or in enhancing existing products.

WE OPERATE IN AN EXTREMELY COMPETITIVE MARKET, AND IF WE FAIL TO COMPETE
EFFECTIVELY, OUR BUSINESS MAY BE HARMED.

    The data storage and semiconductor capital equipment industries are
intensely competitive. Established companies, both domestic and foreign, compete
with each of our product lines. Many of our competitors have greater financial,
engineering, manufacturing and marketing resources than we do. A substantial
investment is required by customers to evaluate, test, select and integrate
capital equipment into a production line. As a result, once a manufacturer has
selected a particular vendor's capital equipment, we believe that the
manufacturer generally relies upon that equipment for the specific production
line application and frequently will attempt to consolidate its other capital
equipment requirements with the same vendor. Accordingly, if a particular
customer selects a competitor's capital equipment, we expect to experience
difficulty in selling to that customer for a significant period of time. We
believe that our ability to compete successfully depends on a number of factors
both within and outside of our control, including:

    - price

    - product quality

    - breadth of product line

    - system performance

    - cost of ownership

    - global technical service and support

                                       6
<PAGE>
    - success in developing or otherwise introducing new products

    We cannot be certain that we will be able to compete successfully in the
future.

THE SUCCESS OF OUR BUSINESS DEPENDS ON CONTINUED MARKET ACCEPTANCE OF OUR
CONNEXION CLUSTER TOOL SYSTEM.


    Our principal product is a line of capital equipment known as the CONNEXION
Cluster Tool system which, together with its associated process modules, is used
to manufacture magnetic recording heads and semiconductor devices. We believe
that continued future growth depends in large part upon our ability to gain
increased customer acceptance for our CONNEXION Cluster Tool system and related
technology. The following table sets forth the percentage of our net sales
derived from sales of the CONNEXION Cluster Tool systems for the periods
indicated:



<TABLE>

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

CONNEXION Cluster Tool system.........................       85%            83%            71%
</TABLE>


    Continued acceptance of the CONNEXION Cluster Tool system will depend on
factors, including:

    - cost of ownership

    - performance and reliability

    - ability to manufacture on a successful and timely basis

    - availability of customer support


    If we fail to continually enhance the CONNEXION Cluster Tool system, the
future marketplace acceptance of that product could be diminished. We cannot
assure you that we will be successful in obtaining increased market acceptance
of the CONNEXION Cluster Tool system or any future enhanced version of the
system. If we fail to gain sufficient customer acceptance for this system, our
business could be harmed.



WE HAVE INVESTED SIGNIFICANT RESOURCES IN THE DEVELOPMENT OF ADVANCED COPPER
DEPOSITION TECHNOLOGY. IF WE FAIL TO SUCCESSFULLY DEVELOP ADVANCED COPPER
DEPOSITION PROCESSES THAT ARE ACCEPTED BY THE MARKETPLACE, OUR LONG-TERM GROWTH
COULD BE DIMINISHED.



    To date, we have invested significantly, and expect to continue investing
significantly in the development of advanced copper deposition technology for
high performance integrated circuit fabrication for the semiconductor market.
Currently, we expect that in fiscal 2000, approximately 20% of our research and
development budget will be dedicated to the development of our copper deposition
technology. The development of this technology is emerging and highly complex
and the market for equipment incorporating this technology is not expected to
reach commercial viability until after 2000. Recently, several semiconductor
device manufacturers have announced that they have made advancements in
copper-based technology. These and other competitors with substantially greater
resources than ours are investing in research and development of similar
technologies and may achieve market acceptance of their products before us. We
cannot assure you that our efforts in this area will be technologically
successful or, even if technologically successful, will be commercially accepted
by the marketplace. If we fail to achieve commercial success in our pursuit of
copper-based technology for the semiconductor industry, our long-term growth
prospects could be diminished.

SALES TO INTERNATIONAL MARKETS CONSTITUTE A SIGNIFICANT AND GROWING PORTION OF
OUR TOTAL REVENUES. OUR OPERATING RESULTS COULD BE HARMED BY ECONOMIC DOWNTURNS
IN FOREIGN MARKETS AND OUR DEPENDENCE ON INTERNATIONAL SALES REPRESENTATIVES.



    An increasing portion of our revenues in recent years has been derived from
sales in international markets. International sales are subject to various
risks. The following table sets forth for the periods indicated the percentage
of our total revenues derived from sales to customers located outside of the
United States:



<TABLE>

Non-U.S. Customers....................................     31%            38%            53%
</TABLE>


We intend to continue to expand our operations outside the United States and
enter additional international markets, which will require significant
management attention and financial resources. International business presents
additional risks, including:

    - periodic recessions in foreign economies as they impact our particular
      sector

    - the risk of government-financed competition

    - changes in trade policies and tariff regulations

    - worldwide political and economic instability

    - difficulties in obtaining U.S. export licenses and managing businesses
      abroad


    Our international sales are denominated in U.S. dollars. As a result,
changes in the value of foreign currencies relative to the value of the U.S.
dollar can render our products comparatively more expensive. Although we have
not been significantly negatively impacted in the past by foreign currency
changes in Japan, Korea, Taiwan and Europe, these conditions could negatively
impact our international sales in future periods. Further, our international
sales are made primarily through several independent sales representatives and a
third-party distributor. We cannot be certain that they will continue to market
and distribute our products successfully, if at all. Our implementation of new
distribution and sales arrangements could result in delays and disruptions in
our international sales and customer support efforts, which could reduce our
sales, damage our reputation and adversely impact our business.



THE LOSS OF ANY OF OUR KEY PERSONNEL COULD ADVERSELY IMPACT OUR ABILITY TO MEET
CUSTOMER AND TECHNOLOGICAL DEMANDS.



    Because of our small size and our need for employees with both executive and
advanced technical skills, we depend in significant part upon the continued
contributions of our officers and key personnel. Our key personnel are critical
to our success, and many of them would be difficult to replace. Many of our
employees are not bound by long-term employment or noncompetition agreements,
and competitors in the high technology industry in which we compete may attempt
to recruit them. The loss of our officers or other key personnel could cause our
business to suffer.



WE MAY HAVE DIFFICULTY ATTRACTING AND RETAINING QUALIFIED PERSONNEL, WHICH COULD
ADVERSELY IMPACT OUR ABILITY TO EXECUTE OUR BUSINESS STRATEGY.


    The competition for personnel throughout our industry can be significant.
Because of this competition for qualified labor, we have occasionally
experienced delays in meeting our staffing requirements. Our future success will
depend on our ability to attract and retain qualified technical, marketing and
management personnel, particularly highly skilled design, process and test
engineers. The market for such personnel has become intensely competitive,
particularly in California where there

                                       8
<PAGE>
has been a significant increase in the business activities of other companies in
the data storage and semiconductor manufacturing sectors.


    Any protracted inability on our part to recruit, train and retain adequate
numbers of qualified personnel could adversely affect our ability to
manufacture, sell and support our products, which could harm our business.


WE MAY EXPERIENCE DIFFICULTY INTEGRATING OUR RECENT ACQUISITION.


    We recently acquired Commonwealth Scientific Corporation. Realization of the
potential benefits from this acquisition may not occur unless the products,
technologies and personnel of Commonwealth are successfully integrated with our
operations in a timely and efficient manner. Any diversion of the attention of
management, and any difficulties encountered in the transition process, could
reduce the revenues of the combined enterprise, or cause the financial condition
and operating results of the combined enterprise to suffer. If we are not able
to successfully integrate Commonwealth and its services and products into our
operations, our business could be harmed.


WE MAY BE UNABLE TO CONSUMMATE POTENTIAL ACQUISITIONS OR SUCCESSFULLY INTEGRATE
THEM WITH OUR BUSINESS WHICH COULD SLOW OUR GROWTH.

    As part of our continued strategy to expand the range of our product
offerings and technologies, we intend to make acquisitions of complementary
businesses, technologies, services or products if appropriate opportunities
arise. However, we may be unable to identify suitable acquisition or investment
candidates at reasonable prices or on reasonable terms. Additionally, regardless
of whether suitable candidates are available, we may be unable to consummate
future acquisitions or investments, which could harm our growth strategy. If we
do consummate acquisitions, we could have difficulty integrating the acquired
products, personnel or technologies. These difficulties could disrupt our
ongoing business, distract our management and employees and increase our
expenses.

WE HAVE A LENGTHY SALES CYCLE WHICH MAY INCREASE OUR EXPOSURE TO CUSTOMER
CANCELLATIONS OR DELAYS IN ORDERS.


    Sales of our systems depend, in significant part, upon the decision of an
existing or prospective customer to add new manufacturing capacity or to expand
existing manufacturing capacity, both of which involve a significant capital
commitment. We may experience delays in finalizing system sales following
initial system qualification while the customer evaluates and receives approvals
for the initial purchase of our systems. In general, for new customers or
applications our sales cycle could take 12 to 18 months to complete. During this
time, we may expend substantial funds and management effort. Lengthy sales
cycles subject us to a number of significant risks, including inventory
obsolescence and fluctuations in operating results over which we have little or
no control.


PROTECTION OF OUR INTELLECTUAL PROPERTY RIGHTS MAY RESULT IN COSTLY LITIGATION.


    There has been substantial litigation regarding patent and other
intellectual property rights in the data storage, semiconductor and related
industries. We have been, and may in the future be, notified of allegations that
we may be infringing intellectual property rights possessed by others. In the
future, protracted litigation and expense may be incurred if necessary to defend
ourselves against alleged infringement of third party rights. Any such
litigation, even if ultimately successful in our defense, could result in
substantial cost and diversion of time and effort by our management, which by
itself could have a negative impact on our business. Adverse determinations in
that litigation could:


    - result in our loss of proprietary rights


    - subject us to significant liabilities, including treble damages in some
      instances


                                       9
<PAGE>
    - require us to seek licenses from third parties, which licenses may not be
      available on reasonable terms or at all

    - prevent us from manufacturing or selling our products


    Any of these outcomes could harm our business.


OUR SUCCESS DEPENDS, IN PART, ON INTELLECTUAL PROPERTY WHICH MAY BE DIFFICULT TO
PROTECT AND COULD AFFECT OUR ABILITY TO COMPETE EFFECTIVELY.


    We believe that our success depends, in part, on our ability to obtain and
protect patents protecting our proprietary technology. As of September 30, 1999,
we had obtained 17 U.S. patents, had received notices of allowance on four U.S.
patent applications and had 37 U.S. patent applications pending. In addition, we
had obtained two foreign patents from the United Kingdom and had 18 foreign
patent applications pending on our behalf as of that date.


    We cannot assure you that:

    - pending patent applications or any future applications will be approved

    - any patents will provide us with competitive advantages or will not be
      challenged by third parties

    - the patents of others will not have an adverse effect on our ability to do
      business


We cannot assure you that others will not independently develop similar
products, duplicate our products or, if patents are issued to us, design around
these patents. In addition, we may be forced to expend time and resources on
protracted litigation to defend our intellectual property rights against third
parties. Further, because patents may afford less protection under foreign law
than is available under U.S. law, we cannot assure you that any foreign patents
issued to us will adequately protect our proprietary rights.


    In addition to patent protection, we also rely upon trade secret protection,
employee and third-party nondisclosure agreements and other intellectual
property protection methods to protect our confidential and proprietary
information. Despite these efforts, we cannot be certain that:

    - others will not independently develop substantially equivalent proprietary
      information and techniques

    - others will not otherwise gain access to our trade secrets

    - others will not disclose our technology

    - we can meaningfully protect our trade secrets

WE DEPEND ON A LIMITED NUMBER OF SUPPLIERS, AND IN SOME CASES SOLE SUPPLIERS.
ANY DISRUPTION OR TERMINATION OF THESE SUPPLY CHANNELS MAY HARM OUR BUSINESS.


    We purchase components, subassemblies and services from a limited number of
suppliers and occasionally from a single source. Disruption or termination of
certain of these sources could occur, and these disruptions could have at least
a temporary adverse effect on our operations. A prolonged inability on our part
to obtain components included in our systems could adversely impact our sales or
our ability to attract and maintain customers.


                                       10

FAILURE BY US TO IDENTIFY AND REMEDIATE ALL MATERIAL YEAR 2000 RISKS COULD CAUSE
A SIGNIFICANT DISRUPTION TO OUR BUSINESS. WE COULD BE REQUIRED TO EXPEND
SIGNIFICANT INTERNAL RESOURCES ON YEAR 2000 REMEDIATION OR THE YEAR 2000
PROBLEMS OF OUR SUPPLIERS COULD CAUSE A DELAY IN SUPPLYING GOODS AND SERVICES TO
US.



    We have identified the following risks you should be aware of:



    - we cannot be certain that the entities on whom we rely for certain goods
      and services that are important to our business will be successful in
      addressing all of their software and systems problems in order to operate
      without disruption in the Year 2000 and beyond



    - although we have made efforts to notify our customers who have purchased
      potential non-compliant products, we cannot be sure that customers who
      purchased such products will not assert claims against us alleging that
      such products should have been Year 2000 compliant at the time of
      purchase, which could result in costly litigation and divert management's
      attention.



    We cannot, however, be certain that we have identified all of the potential
risks. Failure by us to identify and remediate all material Year 2000 risks
could cause a significant disruption of our business.



OUR STOCK PRICE MAY BE VOLATILE DUE TO THE LACK OF A PRIOR PUBLIC MARKET FOR OUR
STOCK AND THE FACT THAT WE OPERATE IN SEVERAL HIGH-TECHNOLOGY INDUSTRIES.



    There has not been a public market for our common stock. We cannot predict
the extent to which investor interest in us will lead to the development of a
trading market or how liquid that market might become. Further, we cannot
guarantee that the price of our common stock will not decline below the initial
public offering price. Stock prices of companies in our industry have
experienced price fluctuations which have often been unrelated to the operating
performance of affected companies. The initial public offering price may not be
indicative of prices that will prevail in the trading market. Various factors
could cause the market price of our common stock to fluctuate substantially.
These factors may include:



    - news announcements relating to us, our competitors, customers or other
      entities regarding quarterly operating results, technology advances or
      production overcapacity


    - general trends in our industry

    - changes in market conditions in the data storage and semiconductor
      industries


    In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted against these companies. This type of litigation, or similar
litigation, could harm our business.


A LIMITED NUMBER OF STOCKHOLDERS WILL HAVE THE ABILITY TO INFLUENCE OUR POLICIES
FOLLOWING THE OFFERING.


    A substantial majority of our capital stock is held by a limited number of
stockholders. After completion of this offering, assuming no exercise of
currently exercisable stock options, our principal stockholders and executive
officers and directors will beneficially own approximately 61% of the shares of
common stock outstanding, 67% if Seagate Technology exercises in full its
warrant to purchase common stock. In particular, Seagate Technology is our
largest stockholder and two of its representatives are members of our board of
directors. Following completion of this offering, Seagate Technology will own
2,428,313 shares representing approximately 21% of our outstanding common stock.
In addition, if Seagate Technology exercises in full a warrant for the common
stock that it holds, it would own an aggregate of approximately 26% of our
outstanding common stock.



    Accordingly, this limited number of stockholders, including Seagate
Technology, will likely for some time influence the election of our board of
directors, control major decisions of corporate policy and


                                       11
<PAGE>

determine the outcome of any major transaction or other matter submitted to our
stockholders or board of directors, including potential mergers or acquisitions
and amendments to our certificate of incorporation. Stockholders other than
these principal stockholders are therefore likely to have little or no influence
on decisions regarding such matters.


THE PRICE OF OUR STOCK COULD DECREASE AS A RESULT OF SHARES BEING SOLD IN THE
MARKET AFTER THE OFFERING.

    The market price of our common stock could drop as a result of sales of a
large number of shares of common stock in the market after the offering, or the
perception that these sales could occur. These factors also could make it more
difficult for us to raise funds through future offerings of common stock.


    There will be 11,492,707 shares of common stock outstanding immediately
after the offering. Of these shares, the shares sold in the offering will be
freely transferable without restriction or further registration under the
Securities Act, except for any shares purchased by our "affiliates" as defined
in Rule 144 under the Securities Act. The remaining 7,992,707 shares of common
stock outstanding will be "restricted securities" as defined in Rule 144. These
shares may be sold in the future without registration under the Securities Act
to the extent permitted by Rule 144 or an exemption under the Securities Act. In
addition, additional shares of common stock subject to outstanding vested stock
options could also be sold. The holders of 7,218,197 shares of common stock will
also have registration rights allowing them to cause us to register their shares
under the Securities Act.

<PAGE>
                                USE OF PROCEEDS


    The estimated net proceeds to us from the sale of 3,000,000 shares of our
common stock in this offering are estimated to be approximately $32.6 million.
This is based on an assumed initial public offering price of $12.00 per share,
after deducting underwriting discounts and estimated offering expenses payable
by us. We will not receive any proceeds from the sale of our common stock by the
selling stockholders.



    We intend to use approximately $15.0 million of the proceeds from the
offering to repay the outstanding balance under several loan agreements. These
loan agreements include: (1) a line of credit with an interest rate at prime
plus 1/4%; (2) a term loan which matures October 2001 with an interest rate at
prime plus 1/2%; (3) a note payable which matures October 2000 with an interest
rate at 8%; and (4) three capital leases with maturity dates of March 2000,
August 2000, and January 2002, and interest rates of 13.9%, 16.5%, and 8.1%. In
addition, we intend to use approximately $10.0 million to redeem the Series D
Redeemable Preferred Stock, approximately $6.3 million for capital expenditures,
including demonstration tools and equipment and expansion and improvement of
existing facilities and the balance of the net proceeds will be used for general
corporate purposes. Pending such uses, our net proceeds from this offering will
be invested in short-term, interest-bearing, investment grade securities. The
Series D Redeemable Preferred Stock is held by Advent International Corporation.
Advent is one of our major stockholders and a representative of Advent is a
member of our Board of Directors.


                                DIVIDEND POLICY


    We have never paid or declared cash dividends on our common stock. We
currently intend to retain all future earnings for our business and do not
anticipate paying cash dividends in the foreseeable future. We are currently
restricted under the terms of some of our credit agreements from paying any
dividends to stockholders without the prior written consent of the lenders.
Future dividends, if any, will depend on, among other things: (1) our operating
results, (2) capital requirements and (3) restrictions in loan agreements.

    The following table sets forth our capitalization as of September 30, 1999.
Our capitalization is presented:


    - on an actual basis;

    - on a pro forma basis to give effect to the automatic conversion of all

      Convertible Preferred Stock into common stock, as well as the conversion
      of Series C Convertible Preferred Stock into common stock and Series D
      Redeemable Preferred Stock, all of which will occur upon the closing of
      this offering; and


    - on a pro forma as adjusted basis to reflect our receipt of the net
      proceeds from the sale of 3,000,000 shares of common stock in this
      offering at an assumed initial public offering price of $12.00 per share
      after deducting the underwriting discount and estimated offering expenses,
      the repayment of approximately $15.0 million of debt, of which
      approximately $12.3 million relates to debt outstanding as of
      September 30, 1999 and the redemption of all outstanding shares of
      Series D Redeemable Preferred Stock for $10.0 million.

                                    DILUTION


    The pro forma net tangible book value of the common stock as of
September 30, 1999 was $30,445,000, or $3.59 per share, after giving effect to
the automatic conversion of all outstanding shares of Series A Convertible
Preferred Stock, Series B Convertible Preferred Stock and Series C Convertible
Preferred Stock into an aggregate of 6,131,940 shares of common stock which will
occur upon the consummation of this offering. After giving effect to the sale of
the common stock pursuant to this offering at an assumed initial public offering
price of $12.00 per share, and after deducting the underwriting discount and
estimated expenses of the offering, the adjusted pro forma net tangible book
value at September 30, 1999 would have been $63,025,000, or $5.48 per share.



    Pro forma net tangible book value per share before the offering has been
determined by dividing pro forma net tangible book value (total tangible assets
less total liabilities) by the pro forma number of shares of common stock
outstanding at September 30, 1999. The offering will result in an increase in
pro forma net tangible book value per share of $1.89 to existing stockholders
and an immediate and substantial dilution of $6.52 to new investors who purchase
shares in the offering. Dilution is determined by subtracting pro forma net
tangible book value per share from the assumed initial public offering price of
$12.00 per share. The following table illustrates this dilution:

(1) The sale by the selling stockholders in the offering will reduce the number
    of shares held by existing stockholders to 7,992,707 shares, or 70% of the
    total number of shares of common stock to be outstanding after the offering
    and will increase the number of shares held by the new investors to
    3,500,000 shares, or 30% of the total number of shares of common stock to be
    outstanding after the offering. See "Principal and Selling Stockholders."



    These tables do not assume exercise of stock options or warrants outstanding
as of September 30, 1999. At September 30, 1999, an aggregate of 2,234,040
shares of common stock were issuable upon the exercise of outstanding options at
a weighted average exercise price of $3.62 per share. Upon consummation of this
offering, a warrant will become convertible into 790,760 shares of common stock
at $5.58 per share. To the extent that outstanding options and this warrant are
exercised in the future, there will be further dilution to new investors.

    The following unaudited pro forma statements of operations for the year
ended September 30, 1999 give effect to the May 10, 1999 acquisition of
Commonwealth Scientific Corporation. The unaudited pro forma statements of
operations are based on the statements of operations for CVC, appearing
elsewhere in this prospectus, and the statements of operations of Commonwealth
as if the acquisition occurred on October 1, 1998. The Commonwealth statements
of operations have been modified to conform to CVC's fiscal year end by
combining the quarterly operating results for the quarters ended December 31,
1998 and March 31, 1999 with the interim results for the period April 1 to
May 9, 1999. These unaudited pro forma statements of operations should be read
in conjunction with the historical financial statements and notes thereto of CVC
and Commonwealth included elsewhere in this prospectus.


    The unaudited pro forma combined statements of operations give effect to the
following pro forma adjustments necessary to reflect the acquisition of
Commonwealth:


    - Reduction in operating expenses related to the restructuring activities
      undertaken, solely comprised of Commonwealth employees terminated as of or
      shortly after the acquisition;



    - Elimination of the write-off of the portion of the purchase price
      allocated in-process research and development, due to its one-time nature;



    - Amortization of goodwill and other intangibles over periods ranging from
      five to seven years; and


    - Decrease in income taxes related to adjustments.


    Amounts are in thousands, except for per share data.

OVERVIEW


    CVC is a worldwide supplier of process equipment used to manufacture
magnetic recording heads for disk drives and advanced semiconductor devices for
computers and communications equipment. CVC's principal product is the CONNEXION
Cluster Tool system, which provides integrated deposition and etch equipment
based on a central substrate handling platform and a series of interchangeable
thin film deposition and etch processing modules. CVC also derives revenue from
the sale of sources, spare parts, enhancements, and field service contracts.
System revenues represented 71% in fiscal 1999, 83% in fiscal 1998 and 85% in
fiscal 1997 of CVC's total revenue. In order to expand its technology and
broaden its offering of process modules, CVC acquired Commonwealth Scientific
Corporation in May 1999. Commonwealth's primary products are ion beam etch, ion
beam deposition and diamond-like carbon process modules for the data storage
industry and ion beam sources principally used by suppliers of optical
equipment.



    CVC's growth in the past four years has been primarily due to the expansion
of the disk drive industry and transition of the industry to magnetoresistive,
or MR, heads and giant magnetoresistive, or GMR, heads. During fiscal 1999,
fiscal 1998 and fiscal 1997, 85%, 77% and 88% of CVC's revenue was derived from
sales made to manufacturers of magnetic recording heads and 9%, 21%, and 9% was
derived from sales to manufacturers of semiconductor devices, with the remainder
of the revenue derived from ancillary products and services. CVC's top four
customers for fiscal 1999, were Seagate, IBM, TDK and Alps, all of whom
manufacture magnetic recording heads. CVC expects that these customers will
continue to account for a significant portion of CVC's fiscal 2000 revenues and
that significant customer concentration will continue for the foreseeable
future.


    CVC recognizes revenue from system sales, enhancements and spare parts at
the time of shipment. Provisions for estimated installation and warranty costs
are recorded at the time revenue is recognized. Revenue on field service
contracts is deferred and recognized on a straight-line basis over the period of
the contract.


    Revenue derived from system sales is dependent upon the timing of orders,
customer requirements for additional manufacturing capacity and CVC's ability to
respond on a timely basis to rapid technological developments. CVC's customers
typically place large orders, which could cause revenues to fluctuate
significantly from period to period. Orders for system sales range in price from
approximately $1.0 million to $4.0 million, depending on the configuration of
the system. For example, in the second half of fiscal 1998 and the first quarter
of fiscal 1999, CVC's revenues were adversely affected by reduced orders from
magnetic head manufacturers, who experienced reduced demands, inventory
surpluses and poor operating results and as a result, deferred capital
expenditures of fabrication equipment. In recent quarters, magnetic head
manufacturers have increased capital spending to acquire new process
technologies that enable them to produce GMR heads. Because the data storage and
semiconductor industries are highly cyclical, and orders in CVC's backlog are
subject to cancellation or rescheduling, CVC's visibility on revenues for future
periods is limited, and its operating results could fluctuate significantly from
period to period.



    International sales accounted for 53%, 38% and 31% of our total revenues in
fiscal 1999, fiscal 1998 and fiscal 1997. CVC expects that international sales
will continue to account for a significant


                                       18
<PAGE>

portion of our revenue in the foreseeable future. CVC's international sales are
denominated in U.S. dollars. As a result, changes in the value of foreign
currencies relative to the value of the U.S. dollar can render our products
comparatively more expensive. Although CVC has not been significantly negatively
impacted in the past by foreign currency changes in Japan, Korea, Taiwan and
Europe, such conditions could negatively impact its international sales in
future periods.



    CVC's gross margin is influenced by a number of factors related to the mix
of revenues within a particular period. For example, systems for new process
applications tend to have lower margins initially than those for existing
processes. As a result, sales to semiconductor manufacturers, whose process
requirements tend to be unique, generally have a lower gross margin than sales
to magnetic recording head manufacturers, who typically purchase systems for
which we have significantly more processing experience. Sales to international
customers typically have a lower gross margin than sales to domestic customers.
In addition, revenues from ion beam sources, enhancements, spare parts and field
service contracts typically have a higher gross margin than system margins. As a
result of these factors, CVC expects its gross margin to fluctuate from period
to period.

</TABLE>



YEAR ENDED SEPTEMBER 30, 1999 COMPARED TO YEAR ENDED SEPTEMBER 30, 1998



    REVENUES.  Revenues increased 21.6% to $82.9 million for the year ended
September 30, 1999 from $68.2 million for the year ended September 30, 1998. The
increase is primarily attributable to additional sales resulting from the
Commonwealth acquisition of $13.3 million and increased sales to data storage
customers of $7.0 million, which offset lower sales of CVC's systems to
semiconductor customers of $7.0 million.



    GROSS MARGIN.  Gross margin increased to 39.1% of revenues for the year
ended September 30, 1999 from 38.4% for the year ended September 30, 1998. Gross
margin contribution in fiscal 1999 was affected by the lower margins of 30.9% on
sales of the product lines from the Commonwealth acquisition. Gross margins
excluding the impact of the Commonwealth acquisition product lines would


                                       19

have been 40.7%. The lower gross margins in fiscal 1998 reflect the higher
percentage of new system sales to semiconductor customers, which usually have
lower margins.



    RESEARCH AND DEVELOPMENT.  Research and development expenses were unchanged
at $12.6 million for fiscal 1999 compared to fiscal 1998. As a percentage of
revenues, research and development expenses decreased to 15.2% for fiscal 1999
compared to 18.5% for fiscal 1998. The higher relative expenditure level in
fiscal 1998 is primarily attributable to material expenses of $0.9 million
associated with the completion of a government contract. Expenses in fiscal 1999
reflect additional research and development expenses of $1.3 million from the
acquisition of Commonwealth, higher depreciation expense of $1.1 million due to
additional capitalization of demonstration tools, partially offset by lower
personnel costs of $0.9 million and lower material costs of $0.2 million related
to internal development projects. Although fiscal 1999 expenditure levels were
unchanged compared to fiscal 1998, CVC believes that research and development
expenditures are essential to maintaining its competitive position in the data
storage and semiconductor markets and expects these expenditure levels to
increase in absolute dollars for the foreseeable future.



    SALES AND MARKETING.  Sales and marketing expenses increased by 31.0% to
$10.1 million for fiscal 1999 from $7.7 million for fiscal 1998. As a percentage
of revenues, sales and marketing expenses increased to 12.2% for fiscal 1999
from 11.3% for fiscal 1998. The increase is attributable to the addition of
personnel and their related expenses of $1.6 million as a result of the
Commonwealth acquisition, additional personnel and related expenses in field
service of $0.6 million to support CVC's expanded product offering and customer
base, and increased expenses of $0.4 million for product demonstrations.



    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
38.7% to $4.8 million for fiscal 1999 from $3.5 million for fiscal 1998. As a
percentage of revenues, administrative expenses were 5.8% for fiscal 1999, and
5.1% for fiscal 1998. The increase in general and administrative expenses
reflects additional administration expenses of $0.5 million due to the
Commonwealth acquisition, as well as additional accruals for doubtful accounts
of $0.3 million, and other accruals for post-employment and pension benefits of
$0.2 million.



    IN-PROCESS R&D WRITE-OFF.  During fiscal 1999, as part of the purchase of
Commonwealth, the value assigned to research expenditures on products in the
development stage which have not reached technological feasibility and for which
there is no alternative future use were written off in accordance with
applicable accounting rules. This write-off amounted to approximately
$1.2 million.



    The in-process technology acquired from Commonwealth consists of four
technology groupings: ion source products, etch modules, deposition modules, and
dielectric deposition modules, which have assigned values of $0.2 million,
$0.5 million, $0.3 million and $0.2 million. Descriptions of these groupings are
as follows:



    - Ion source products, including both ion sources and power supplies, are
      being designed for use in applications that include etching, deposition,
      surface modification, and ion assist.



    - The etch modules are being designed to support the market requirements for
      ion beam processing applications.



    - The deposition modules are being designed to support very thin metallic
      film through ion beam sputter deposition of target materials.



    - The dielectric deposition modules are being designed to support very thin
      dielectric film through ion beam sputter deposition of target materials.


                                       20

    As of the date of acquisition, $4.5 million had been expended to develop
these R&D projects. The estimated cost to complete these projects is
approximately $2.9 million, to be incurred through fiscal 2000.



    There is a risk associated with the completion of the R&D projects, and CVC
cannot assure that any of the projects will have technological and commercial
success without the successful completion of the remaining R&D efforts on the
acquired in-process technologies. Without the successful completion of the
remaining R&D efforts, CVC would not realize the future revenues and profits
attributed to the acquired R&D. CVC believes, however, that the failure of any
particular in-process R&D project would not materially impact CVC's financial
position or operating results.



    At September 30, 1999, the estimated development completion dates and costs
of the in-process R&D projects acquired from Commonwealth are consistent with
the estimates made at the acquisition date.



    INTEREST AND OTHER, NET.  Interest and other, net decreased to $0.2 million
for fiscal 1999 from the $1.2 million for fiscal 1998. The decrease in interest
and other, net primarily reflects reduced interest expense of $0.1 million due
to the reduction of borrowings with the proceeds from the sale of preferred
stock in December 1998, a one-time gain of $0.4 million associated with the sale
of two non-core product lines and a one-time lawsuit settlement of $0.5 million
for patent infringement.



    INCOME TAXES.  Income tax expense for fiscal 1999 amounted to $1.9 million
compared to $0.3 million for fiscal 1998. The effective tax rate for fiscal 1999
was 55.2% compared to the effective rate of 50.9% for fiscal 1998. The increase
is the result of the non-deductible in-process R&D write-off.



YEAR ENDED SEPTEMBER 30, 1998 COMPARED TO YEAR ENDED SEPTEMBER 30, 1997



    REVENUES.  Revenues increased 8.9% to $68.2 million in fiscal 1998 from
$62.6 million in fiscal 1997. The increase in revenues is primarily attributable
to increased systems sales of $7.4 million and spare sales of $0.9 million to
new semiconductor customers. The majority of this increased volume was to new
customers placing their initial system order. Partially offsetting these
increases was decreased system sales to data storage customers by $5.0 million
as demand decreased due to a general downturn in the industry.



    GROSS MARGIN.  Gross margin increased to 38.4% of revenues in fiscal 1998
from 34.0% in fiscal 1997. The margin improvement was attributable to lower
systems manufacturing costs as the result of efficiencies derived from repeat
orders and increased sales of higher margin spares at 57% and enhancements at
64%.



    RESEARCH AND DEVELOPMENT.  Research and development expenses increased 39.3%
to $12.6 million in fiscal 1998 from $9.1 million in fiscal 1997. As a
percentage of revenues, research and development expenses increased to 18.5% in
fiscal 1998 from 14.5% in fiscal 1997. The increase is attributable to increased
expenditures for an expanded demonstration program of $0.3 million, increased
personnel costs due to the hiring of engineers in the fourth quarter 1997 to
support the expanded demonstration program and new development projects of $1.5
million, increased depreciation of $0.6 million as well as expenses related to
government contracts of $0.5 million.



    SALES AND MARKETING.  Sales and marketing expenses increased 37.1% to
$7.7 million in fiscal 1998 from $5.6 million in fiscal 1997. As a percentage of
revenues, sales and marketing expenses increased to 11.3% in fiscal 1998 from
9.0% in fiscal 1997. The increase is attributable to the addition of marketing
personnel to support the semiconductor market of $0.5 million, the addition of
field service personnel of $0.8 million, increased trade show and advertising
expense of $0.3 million, and higher commissions resulting from increased system
sales of $0.1 million.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
36.9% to $3.5 million in fiscal 1998 from $2.5 million in fiscal 1997. As a
percentage of revenues, general and administrative expenses increased to 5.1% in
fiscal 1998 compared to 4.0% in fiscal  1997. The increase is attributable to
the full year impact of additional employees hired in fiscal 1997 as well as
several new hires in
fiscal 1998 of $0.4 million, an increase of $0.2 million in consulting services
directly related to the implementation of a new computer system and an increase
of $0.1 million in depreciation for computer systems installed in fiscal 1998
and fiscal 1997.


    INTEREST AND OTHER, NET.  Interest and other, net increased to $1.2 million
in fiscal 1998 from $0.6 million in fiscal 1997, reflecting an increase in
borrowings on the credit line and interest expense on a new $8.0 million term
loan.

    WRITE-OFF OF DEFERRED CHARGES.  In fiscal 1997, costs were incurred relative
to preparing CVC for its initial public offering. During the fourth quarter of
fiscal 1998, the intent to complete the public offering was withdrawn due to
continued weakness in the data storage and semiconductor industries and the
equity market for initial public offerings and, accordingly, these costs were
charged against current period earnings.


    INCOME TAXES.  Income tax expense in fiscal 1998 was $0.3 million compared
to $1.5 million in fiscal 1997. The effective tax rate for fiscal 1998 was 50.9%
compared to the effective rate of 41.6% in fiscal 1997. The increase of 9.3% was
due to permanent non-tax deductible expenses and a low level of profitability,
partially offset by the utilization of a valuation allowance related to net
operating loss carryforwards.

</TABLE>



    CVC's quarterly and annual operating results are affected by a wide variety
of factors that could materially and adversely affect revenues and profitability
from period to period, including:


    - specific economic conditions in the data storage and semiconductor
      industries

    - the timing of significant orders

    - cyclical patterns of capital spending by customers

    - modification or cancellation of customer orders

    - continued market acceptance of our systems and our customers' products

    - shipment delays

    - loss of a significant customer

    - increased research and development or marketing costs associated with our
      introduction of new products

    - introduction of new products by our customers

                                       23
<PAGE>
    - our ability to successfully introduce new products on a timely basis

    - changes in our pricing policies or those of our competitors

    - production and quality problems

    - the publication of opinions by industry analysts about us, our products or
      our competitors


    CVC's revenues have fluctuated over the past eight quarters primarily due to
the overall decline in the data storage and semiconductor markets in 1998, which
adversely affected CVC's sales for the last two quarters of fiscal 1998 and the
first quarter of fiscal 1999. CVC's quarterly gross margin is influenced by a
number of factors relating to the level and mix of revenues for products
carrying different gross margins, as well as the type of customer, whether data
storage or semiconductor manufacturers, and type of order, whether a repeat or
new application. Repeat orders generally have lower costs associated with the
order due to manufacturing efficiencies. Gross margin as a percentage of sales
increased during the last two quarters of fiscal 1998 and the first quarter of
fiscal 1999 due to: (1) a higher percentage of total revenues generated from
increased sales of spare parts and enhancements carrying relatively higher gross
margins and (2) a higher percentage of total system revenues generated from
repeat system sales to data storage customers carrying relatively higher gross
margins. Gross margin as a percentage of sales decreased during the third and
fourth quarters of fiscal 1999 in part due to the consolidation of
Commonwealth's operating results from May 10, 1999, the date of the acquisition.



    Sales and marketing as a percentage of sales increased during the fourth
quarter of fiscal 1998 due to an increase in advertising, customer
demonstrations and exhibits expense. Sales and marketing as a percentage of
sales increased during the fourth quarter of fiscal 1999 due to an increase in
distribution commisions, employee relocation and customer service expenses
associated with the integration of Commonwealth. General and administrative
expenses as a percentage of sales increased during the fourth quarter of fiscal
1999 due to an increase in allowances for bad debt, accounting fees and business
system implementation all associated with the integration of Commonwealth.


    Due to potential quarterly fluctuations in operating results, CVC believes
that quarter-to-quarter comparisons of its results of operations should not be
relied upon as indicators of future performance. Further, in the event that in
some future quarter CVC's net sales or operating results were below the
expectations of public market securities analysts and investors, the price of
the common stock would likely be materially adversely affected.

LIQUIDITY AND CAPITAL RESOURCES


    In recent years, CVC has financed its capital and operating needs
principally through the sale of $10.0 million of its preferred securities,
advances from customers, and borrowings under various credit facilities. As of
September 30, 1999, CVC had working capital of $22.1 million, including cash and
cash equivalents of $0.4 million, compared to working capital of $10.9 million
and $9.3 million at September 30, 1998 and 1997. Operating activities in fiscal
1999 used cash flow of $4.8 million, as compared with fiscal 1998 in which
operating activities used cash of $6.9 million and fiscal 1997 in which
operating activities provided cash of $3.1 million. In fiscal 1999, increased
accounts receivable and reduced customer advances used cash of $12.0 million and
$2.4 million, respectively, and were partially offset by increased depreciation
of $4.2 million, increased net income of $1.6 million reduced inventories of
$1.4 million, in process R&D write-off of $1.2 million, increased accounts
payable of $0.7 million, and decreased other assets of $0.5 million. The
significant increase in the use of cash for accounts receivables from 1998 to
1999 is due to the increased fourth quarter revenue year over year from
$13.9 million to $27.1 million. The use of cash in operating activities in
fiscal 1998 was a direct result of a $7.5 million decrease in advances from
customers generally attributable to lower order rates from customers, and a
$2.8 million decrease in accounts payable. These decreased liabilities were
partially offset by $2.2 million in depreciation and reduced levels of
receivables and inventory, which provided cash of $1.3 million and
$1.7 million, respectively. These net changes reflect lower fourth quarter sales
in fiscal 1998 as compared to fiscal 1997 by approximately $5.1 million combined
with


                                       24
<PAGE>

overall inventory level reductions. Of the cash provided from operating
activities in 1997, net income provided $2.0 million, depreciation and
amortization another $1.3 million, and increases in accounts payable, advances
from customers, and other liabilities provided $4.6 million, $3.0 million and
$1.3 million, respectively. Increases in accounts receivable and inventories
used $3.4 million and $5.8 million of operating cash flow in 1997.



    In fiscal 1999, 1998 and 1997, CVC invested $4.0 million, $6.6 million and
$2.8 million, respectively, in capital expenditures. The capital expenditures
were primarily for facilities, machinery and equipment, computers and related
equipment, and demonstration system tools. CVC has invested heavily in
demonstration tools for use at its facilities in order to demonstrate new
product capabilities for its magnetic head and semiconductor device customers.
Although CVC currently has no significant capital commitments, it expects to
spend approximately $6.0 million on capital expenditures over the next
12 months.



    As of September 30, 1999, CVC's principal source of liquidity consisted of a
$15.0 million line of credit under a demand line and term loan agreement, under
which there were $10.7 million in borrowings. As of the end of the third quarter
in fiscal 1999, CVC was not in compliance with one financial test relating to
minimum backlog levels to be met under the agreement and thus, CVC was in
technical default of the agreement. The lender has waived in writing its rights
regarding prior lack of compliance and, as of September 30, 1999, CVC was in
compliance with all covenants in this agreement. Borrowings associated with term
loans from a commercial bank as of September 30, 1999 amounted to $8.0 million.
One such loan requires monthly payments of principal and interest at prime plus
1/2% while the other term loan requires monthly payments of principal and
interest at 8.39%. CVC also has available an equipment line of credit at
September 30, 1999 which allows for maximum borrowings of $3.0 million.
Borrowings under the agreement are at an interest rate of prime. There are no
amounts outstanding under the equipment line of credit at September 30, 1999.
CVC has a mortgage credit facility which requires monthly payments of principal
and interest at 5.29% on the first $500,000 of the mortgage credit facility
through October 1, 1999, after which the rate increases to 8.29% through
September 30, 2002, consistent with the interest rate on $1,500,000 of the
credit facility. Subsequent to September 30, 2002, CVC may select the interest
rate on the remaining principal from fixed or variable interest rate
alternatives.



    CVC's principal liquidity requirements are expected to be for working
capital, capital expenditures, demonstration equipment, and if appropriate,
acquisitions. CVC intends to use the proceeds of the offering for general
corporate purposes, including approximately $6.3 million for capital
expenditures relating to facility expansion and manufacturing and demonstration
equipment, $15.0 million for repayment of debt, $10.0 million to reduce the
Series D Redeemable Preferred Stock, and the balance for additional working
capital. See "Use of Proceeds." CVC believes that cash from operations, and bank
borrowings, together with the net proceeds of the sale of common stock by CVC in
the offering, will be adequate to fund operations for at least the next
12 months.



    CVC's long-term capital requirements will be affected by many factors,
including the success of CVC's current product offerings, CVC's ability to
enhance its current products and to develop and introduce new products that keep
pace with technological developments and general trends in the data storage and
semiconductor industries. CVC plans to finance its long-term capital needs with
the net proceeds of this offering, together with borrowings and cash flow from
operations. To the extent that such funds are insufficient to finance CVC's
activities, CVC will have to raise additional funds through the issuance of
additional equity or debt securities or through other means. There can be no
assurance that additional financing will be available on acceptable terms.


YEAR 2000


    The Year 2000 issue is the result of computer programs using two digits
rather than four to define the applicable year. Any of CVC's computer programs
or hardware or other equipment that have date-sensitive software or embedded
chips may recognize a date using "00" as the year 1900 rather


                                       25
<PAGE>

than the year 2000. This could result in a system failure or miscalculations
causing disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices or engage in similar normal
business activities.



    In order to upgrade its overall business systems' hardware and software and
to enable those systems to properly use dates beyond December 31, 1999, CVC
installed a new business system in May 1999 which has been certified by the
vendor as Year 2000 compliant. In addition, CVC is in the process of completing
its inventory and assessment of its desktop systems and laptops. CVC currently
uses standard "off the shelf" vendor-supplied software on its desktop systems
and laptops. Many of these vendors are still implementing their Year 2000
compliance programs and CVC will implement the Year 2000 compliant versions as
required when those solutions are available. CVC has run internal tests on its
desktop systems and laptops and believes it has identified those systems and
laptops which require upgrade or replacement. CVC currently expects that such
remediation efforts will be complete by November 1999. CVC believes that with
these and other modifications or replacements of its business systems' existing
software and, in some cases, hardware, its computer programs should be able to
continue to operate effectively after December 31, 1999. However, if such
modifications and replacements are not made, or are not completed in a timely
manner, the Year 2000 issue could have a material adverse impact on CVC's
operations. With respect to its facilities and technical support systems such as
security, voice mail and phone systems, CVC has contacted its suppliers of those
systems and suppliers have informed CVC that the non-information technology
systems they provide to CVC are Year 2000 compliant.



    CVC also relies directly and indirectly on the external systems of its
customers, suppliers, subcontractors, utilities providers and other third
parties. CVC has contacted these third parties about their Year 2000 readiness.
These third parties have either informed CVC that the systems they provide to
CVC are either Year 2000 compliant or are in the process of upgrading those
systems that are not Year 2000 compliant. For those systems that are not Year
2000 compliant, CVC and the particular supplier are in the process of upgrading
the affected systems, a process which CVC currently expects to be complete by
November 1999. To date, CVC is not aware of any third-party Year 2000 issues
that could materially impact its results of operations, liquidity or capital
resources. However, CVC has no means of ensuring that the third parties that it
deals with will be Year 2000 ready. If the systems of any third parties with
which CVC interacts experience Year 2000 problems, CVC's business, financial
condition or results of operations could be materially adversely affected. CVC
cannot be certain that the systems of third parties with which it interacts will
not suffer from Year 2000 problems.



    CVC's new products are designed to be Year 2000 ready; however, some of its
older products will require upgrades for Year 2000 readiness. CVC intends to
provide, in some cases upgrades for these older products, some of which will be
provided to customers without charge. Notwithstanding these efforts, if any of
CVC's products fails to perform or causes a system malfunction due to the onset
of Year 2000, customers could bring claims against CVC, which could have a
material adverse effect on CVC's business, results of operations or financial
condition. Moreover, CVC's customers could choose to convert to other Year 2000
ready products in order to avoid such malfunctions, which could have a material
adverse effect on CVC's business, results of operations or financial condition.



    CVC has formulated a Year 2000 contingency plan. CVC's reasonably likely
worst case scenario with respect to the Year 2000 issue would be disruption of
its internal operating systems, particularly its accounting and billing systems.
A disruption of this type may adversely impact CVC's business by creating a
delay in payment by our customers and a corresponding increase in CVC's accounts
receivable. We may also be required to purchase alternative hardware and
software systems, incurring additional costs and suffering additional delays
associated with implementing new systems. While we are confident we would be
able to remediate these problems, the delays associated with remediation would
harm our business. CVC cannot be certain, however, that any measures it adopts
will prevent the occurrence of Year 2000 problems, which could have a material
adverse effect on its business, results of operations or financial condition.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS


    Effective October 1, 1998, the Company adopted Statement of Financial
Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income", which
establishes new rules for the reporting and display of comprehensive income and
its components; however, the adoption had no impact on the Company's net income
or stockholders' equity. SFAS No. 130 requires changes to the minimum pension
liability, to be included in other comprehensive income. Prior year financial
statements have been reclassified to conform to the requirements of SFAS No.
130.



    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position (SOP) 98-5, "Reporting on the Costs of Start-Up Activities."
Start-up activities are defined broadly as those one-time activities relating to
opening a new facility, introducing a new product or service, conducting
business in a new territory, conducting business with a new class of customer,
commencing some new operation or organizing a new entity. Under SOP 98-5, the
cost of start-up activities should be expensed as incurred. SOP 98-5 is
effective for CVC's fiscal year 2000 financial statements and CVC does not
expect its adoption to have a material effect on its financial condition or
results of operations.



    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The new standard
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. SFAS No. 133 is effective for all quarters of fiscal years
beginning after June 15, 2000. CVC does not expect SFAS No. 133 to have a
material effect on its financial condition or results of operations.

INTRODUCTION


    CVC is a worldwide supplier of process equipment used to manufacture
magnetic recording heads for disk drives and advanced semiconductor devices for
computers and communications equipment. Our equipment either deposits or removes
thin film layers as steps in the process of manufacturing magnetic recording
heads and semiconductor devices. Since 1993, we have shipped more than 100
CONNEXION Cluster Tool systems, including more than 400 process modules. Our
customers include many of the leading manufacturers of magnetic recording heads
for the data storage industry such as Alps, Fujitsu, IBM, Read-Rite, Seagate
Technology, TDK and Yamaha, as well as manufacturers of semiconductor devices
such as Anadigics, Analog Devices, Honeywell and M/A-COM.


INDUSTRY BACKGROUND

    THE DATA STORAGE INDUSTRY


    In order to satisfy market demand for devices with greater storage capacity,
the disk drive industry has developed new types of recording heads enabling
greater areal density. Areal density is the measure of stored bits per square
inch in the recording surface of a disk. According to data storage industry
sources, areal densities have been increasing approximately 60% per year since
1990. The growth in areal density, or storage capacity, has been facilitated by
the evolution of recording head manufacturing technology from inductive heads
to, or MR heads, magnetoresistive heads to the more recent introduction of giant
magnetoresistive heads, or GMR heads.



    According to TrendFocus, giant magnetoresistive head shipments are expected
to increase from 0.4 billion units in 1999 to 1.2 billion units in 2002, while
the shipment of magnetoresistive heads are expected to decrease from
0.5 billion units in 1999 to limited shipments by 2002. The disk drive
industry's expected growth and transition to technologically advanced recording
heads reflect a number of factors, including:


    - the exchange of increasing volumes of data among users across the Internet
      and intranets;

    - the rapid accumulation of data resulting from growth of digital content,
      including audio, video and data;

    - continued improvements in computing price performance ratios, including
      the emergence of the sub-$1,000 personal computer; and

    - the introduction of new applications for storage devices such as digital
      cameras, auto navigation, video on demand and personal digital assistants,
      or PDAs.


    Magnetic recording heads are manufactured using various thin film deposition
and etch processes, which provide magnetic, conductive and insulating
properties. More advanced heads typically require the deposition of
approximately 18 to 28 thin film layers of different materials. CVC believes
that the data storage industry's current transition to more advanced
technologies will require the data storage industry to make investments in
advanced processing equipment to support both the technology transition and
anticipated volume growth.


    THE SEMICONDUCTOR INDUSTRY


    The manufacture of semiconductors involves multiple thin film processing
steps. Certain types of semiconductor devices that utilize exotic substrates,
such as Gallium Arsenide, or GaAs, are more difficult to produce due to physical
characteristics such as lower maximum tolerable processing temperatures and less
mechanical strength of the substrates. However, these substrates enable the
fabrication of high-speed, high-performance devices with low power consumption
that make them ideally suited for advanced communications applications, such as
portable communication devices, including digital pagers and cellular phones.
Due to the characteristics of these exotic substrates, the fabrication of
devices involving these substrates requires advanced process equipment that can
provide multiple, highly uniform, precision thin film materials.


                                       28
<PAGE>

    In order to increase the performance and reduce the cost of semiconductor
devices, manufacturers have continued to shrink line widths, while at the same
time adding multiple layers of metal interconnect materials. Semiconductor
manufacturers currently use aluminum or aluminum alloys to interconnect the
various layers of a semiconductor device. As semiconductor line widths shrink
below 0.18 microns, or 0.18 millionths of a meter, copper is increasingly being
used as an alternative to aluminum interconnects. Copper provides less
resistance to electron flow at narrow line widths and makes it possible to build
high speed devices using fewer interconnect layers than would be necessary with
aluminum. The deposition of copper interconnect material requires two steps:
(1) the deposition of a barrier layer, to protect the insulating layers from
being contaminated by copper, and (2) the deposition of seed and copper fill
layers, which serve as the interconnect. The deposition of interconnect material
involves very specialized substrate processing equipment, including metal
deposition equipment. According to Dataquest, copper deposition equipment sales
are expected to grow from $200 million in 1999 to $700 million in 2003.


    SUBSTRATE PROCESSING


    The manufacture of magnetic recording heads and semiconductors requires from
tens to hundreds of fabrication processing steps. Many of these steps involve
the controlled application or removal of layers of materials to or from a base
material, or substrate, or on a previously deposited layer. The application of
materials to a wafer, known as deposition, involves the building up of extremely
thin films of electrically insulating or conducting materials. These layers can
range from over one-thousandth to less than one-millionth of a millimeter in
thickness. A wide range of materials and deposition processes are used to build
up thin film layers on substrates to achieve specific performance
characteristics. The removal of material from substrates, known as etching,
involves the precise removal of residue or excess material using dry plasma or
ion beams in order to build a specific pattern, for example, to form a
semiconductor device.



    The process of manufacturing magnetic recording heads and semiconductors is
constantly evolving to address the demand for smaller devices with higher
performance. Devices with smaller features sizes and higher levels of
performance require new materials or more manufacturing steps involving multiple
layers of thin film materials. To successfully develop new manufacturing
processes, thin film recording head and semiconductor manufacturers require
sophisticated processing equipment that:


    - incorporates highly specialized processing and systems knowledge;

    - enables the precise, uniform deposition of a wide range of thin film
      materials;

    - supports a variety of deposition and etching processes on an integrated
      platform; and


    - provides the ability to transition to new materials and fabrication
      processes efficiently.

    FLEXIBILITY OF MODULAR DESIGN.  The modular design of the CONNEXION Cluster
Tool system provides customers the flexibility to cost effectively transition
from the development stage to full production. In the development stage,
customers can use a process module as a fully-functional, stand-alone tool to
develop and test individual fabrication steps. Following the successful
development of individual process steps, a customer can combine multiple process
modules with CVC's CONNEXION Cluster Tool platform to form an integrated
production system. Furthermore, the modular design allows customers to
reconfigure systems that are in production to address the evolving manufacturing
processes required by magnetic recording head and semiconductor manufacturers.
The flexibility to exchange modules enables customers to quickly develop new
fabrication processes, improving time-to-market of higher performance products,
with a lower capital investment.


    BENEFITS OF INTEGRATED PLATFORM.  The integrated platform of the CONNEXION
Cluster Tool system provides customers with the ability to combine various
deposition and etching modules on a single platform in a vacuum controlled
environment. The benefits of a vacuum controlled environment include high
uniformity and reduced incidences of cross contamination and damage from
external handling. CVC's integrated platform enables customers to achieve
improved manufacturing yields, enhanced tool uptime and device reliability and
performance.

    HIGHLY SPECIALIZED PROCESS SOLUTIONS.  CVC provides customers highly
specialized process solutions, including a variety of energy sources and
components. These solutions enable CVC's customers to achieve high uniformity
over a wide range of substrate materials and sizes, as well as control of the
composition materials, atomic microstructures and surface/interface properties.

CVC PROCESS MODULES


    CVC offers process modules for different methods of depositing thin films on
a wafer, or substrate, such as physical vapor deposition, mainly a physical
technique, and chemical vapor deposition, mainly a chemical technique. CVC also
offers modules for different methods of removing, or etching, portions of thin
films from a wafer or a substrate. CVC obtained its ion beam deposition, etching
and its diamond like carbon processing modules through its acquisition of
Commonwealth Scientific Corporation in May 1999.



    Below is a brief description of CVC's process modules:


PHYSICAL VAPOR DEPOSITION--PLASMA SPUTTERING MODULE


    Physical vapor deposition, or PVD, by plasma sputtering is used to deposit a
wide range of magnetic, conductive and insulating materials on various
substrates with different topographies. PVD is performed in a high vacuum
chamber by applying a strong direct current or radio frequency electric field to
an inert gas, usually argon, to create a plasma. The electrically charged ions
are accelerated toward a target made of the material which is to be deposited.
When the ions hit the target, atoms are physically knocked off the target and
are scattered on the wafer or substrate, slowly building up a thin film layer.
CVC offers both a single wafer PVD module and a multi-station PVD module for the
sequential deposition of various materials within a single vacuum chamber.


PHYSICAL VAPOR DEPOSITION--ION BEAM DEPOSITION MODULE


    PVD by ion beam deposition is used to deposit a wide range of very thin
magnetic, conductive and insulating materials on various substrates with
different topographies. Ion beam deposition is performed in a high vacuum
chamber by focusing an ion beam generated by a radio frequency or direct current
ion beam source toward a target made of the desired material to be deposited.
The beam of energetic ions hits the target and ejects atoms of the desired
material toward the wafer or substrate, building up a thin film layer in a
slower, more directional manner than with sputtering. In addition, in some


                                       33
<PAGE>

processes, a second ion beam is directed toward the substrate to control the
microstructure of the thin film while depositing the desired material.


METAL-ORGANIC CHEMICAL VAPOR DEPOSITION MODULE


    Metal-organic chemical vapor deposition, or MOCVD, is used to deposit
various materials such as aluminum, copper, tungsten, titanium, titanium
nitride, tantalum and tantalum nitride. The MOCVD process causes precursor
materials that contain atoms of the material to be deposited to react at the
heated wafer or substrate surface resulting in the formation of the thin film
layer of the material. MOCVD uses a metal organic compound distributed through a
liquid delivery system as the source of the material to be deposited.


ION BEAM ETCH MODULE


    Etching by ion beam is used to transfer a desired device pattern to the
substrates. An ion beam directed toward the substrate can also be used to remove
contaminants such as oxide layers or for substrate conditioning to improve
adhesion. Ion beam etching is performed in a high vacuum chamber by focusing an
ion beam generated by a radio frequency and direct current ion beam source
toward the wafer or substrate.



DIAMOND-LIKE-CARBON MODULE



    Ion beam deposition of thin diamond-like-carbon, or DLC, is used to deposit
hard coating layers as wear and corrosion protection for thin-film heads and
magnetic media. The ion beam diamond-like-carbon module employs a
carbon-containing gas flow through an ion source mounted onto a vacuum process
chamber to deposit thin layers of diamond-like-carbon on wafers or other
substrates. CVC's ion beam diamond-like-carbon deposition system sources are
currently used in production by the thin-film head manufacturers. As hard disk
storage densities increase, the distance between the recording head and magnetic
media are decreasing to below 100 Angstroms. The next-generation advanced giant
magnetoresistive heads will require dense and defect-free diamond-like-carbon
films below 50 Angstroms. To address this requirement, CVC has developed a
filtered cathodic arc diamond-like-carbon deposition cluster module which
enables controlled deposition of high-quality ultrathin diamond-like-carbon
layers. This cluster module will enable CVC to effectively serve the
diamond-like-carbon application for several future generations of thin film
recording heads and magnetic media.


INDUCTIVELY-COUPLED-PLASMA SOFT CLEAN MODULE

    CVC offers a multi-zone inductively-coupled-plasma, or ICP, soft clean
module for surface preparation prior to material depositions. CVC's ICP module
technology employs the design features of the ICP system licensed by CVC from
Texas Instruments and enhanced by CVC through internal developments. The ICP
module design provides the capability for damage-free cleaning of semiconductor
surfaces in order to enable formation of low resistivity interconnect structures
such as with copper metallization and with controlled device interfaces for
enhanced interconnect reliability and performance.

RAPID THERMAL PROCESSING/RAPID THERMAL CHEMICAL VAPOR DEPOSITION MODULE


    CVC's rapid thermal processing, or RTP, module with multi-zone temperature
control optimizes temperature and process uniformity and repeatability control.
CVC's RTP and rapid thermal chemical vapor deposition, or RTCVD, module is
designed for various thermal processing applications including anneal, oxidation
and CVD processes.


                                       34
<PAGE>
600 SERIES PHYSICAL VAPOR DEPOSITION SYSTEMS


    Introduced in 1988, the 610 and 611 products are PVD sputtering deposition
systems, handling up to 6-inch diameter substrates. The 611 system is equipped
with a loadlock and eight work stations enabling up to eight materials to be
deposited with sequential or co-sputter deposition processes. The CVC 600 Series
system is the basic design with many 611 features but without the loadlock and
less automated process control. A soft clean ion source can be installed in any
work station for low damage cleaning of semiconductor surfaces.


ION BEAM SOURCES AND POWER SUPPLIES


    With its acquisition of Commonwealth, CVC obtained a range of ion sources,
as well as the power supplies used to operate these sources. Ion beam processing
is used in a variety of advanced research and development applications, as well
as the production of thin film etch and deposition applications where precise
control and repeatability of multilayer thin films are critical. CVC provides
these products as components to companies supplying equipment to the precision
optics, opthalmics and optoelectronics industries. In addition, CVC uses its ion
beam sources and power supplies in its IBD, IBE and DLC process modules.


CUSTOMERS


    CVC's customers include many of the leading manufacturers of thin film
magnetic recording heads for the data storage industry, as well as manufacturers
of semiconductor devices. During fiscal year 1999, approximately 85% of CVC's
revenues were derived from sales made to thin film magnetic recording head
manufacturers and approximately 9% of CVC's revenues were from sales to
semiconductor device manufacturers. Customers of CVC who have purchased at least
one system from it during fiscal 1998 and 1999 include:

</TABLE>



    Of these customers, Seagate, IBM and TDK each accounted for 10% or more of
CVC's revenues in fiscal 1999 and Seagate, Headway and Alps each accounted for
10% or more of CVC's revenues in fiscal 1998.


RELATIONSHIP WITH SEAGATE TECHNOLOGY


    Seagate Technology, which provides products for storing, managing and
accessing digital information on computers and data communications systems, is
CVC's largest customer, as well as its largest stockholder. Seagate Technology
accounted for 47% of CVC's total revenue in fiscal 1997, 31% of CVC's total
revenue in fiscal 1998 and 34% of CVC's total revenue in fiscal 1999. In
addition, Seagate Technology is CVC's largest stockholder. In 1995, Seagate
Technology made an equity investment of approximately $9.0 million in CVC. In
connection with this investment, Seagate


                                       35
<PAGE>

Technology obtained the right to elect two members of CVC's Board of Directors.
That right will terminate upon consummation of this offering.



    Following completion of this offering, Seagate Technology will own shares
representing approximately 21% of CVC's outstanding common stock. In addition,
pursuant to a warrant acquired by it in 1995, Seagate Technology has the right
to acquire an additional 790,760 shares of common stock at an exercise price of
$5.58 per share. Assuming full exercise of this warrant, Seagate Technology
would own an aggregate of approximately 26% of CVC's outstanding common stock
following completion of this offering.


BACKLOG


    CVC's backlog consists generally of product orders for which a purchase
order has been received and which are scheduled for shipment within twelve
months. Because a large percentage of CVC's orders require products to be
shipped in the same quarter in which the orders are received, and due to
possible changes in delivery schedules, cancellations of orders and delays in
shipment, CVC does not believe that the level of backlog at any point in time is
an accurate indicator of its performance.


MARKETING AND SALES


    CVC sells its products in the United States and Europe through its direct
sales force that is supported by its 29-person marketing and sales organization.
In Japan and Europe, CVC uses distributors to sell its products. CVC markets its
products in China, Korea, Taiwan, Malaysia, Singapore and Thailand through
independent sales representatives. International sales accounted for 31% of
CVC's total revenues for fiscal 1997, 38% for fiscal 1998 and 53% for fiscal
1999. CVC's sales and marketing organization uses a consultative sales process,
working closely with customers to understand and define their deposition process
and equipment needs and to determine that those needs are addressed by CVC's
process technologies, as well as complementary technologies offered by other
equipment providers. CVC works closely with the senior management and research
and development personnel of its existing customer base to gain insight into
their industries and to focus on selling new process technologies tailored to
their customers' requirements.


    The sales cycles for CVC's systems vary depending upon whether the system is
an initial purchase or a repeat order. New customer sales cycles are typically
12 to 18 months, whereas repeat order sales cycles are typically four to six
months. The sales cycle for a new customer begins with the generation of a sales
lead, which is followed by qualification of the lead, an analysis of the
customer's particular applications needs and problems, one or more presentations
to the customer, frequently including extensive participation by CVC's senior
management, two to three product sample demonstrations, followed by customer
testing of the results and extensive negotiations regarding the equipment's
process and reliability specifications. New customer sales cycles are monitored
closely by senior management for correct strategy approach and prioritization.

CUSTOMER SERVICE AND SUPPORT


    Prompt and effective field service and support is critical to CVC's sales
efforts, due to the substantial commitments made by customers that purchase
CVC's equipment. As of September 30, 1999, CVC had 53 full-time employees
dedicated to customer service and support. CVC's strategy of supporting its
installed base through both customer support and research and development groups
has served to encourage the use of CVC's equipment and process technologies in
customer production applications. CVC's engineers and field support personnel
work closely with customers to help define their production and process
requirements, and customers often collaborate in trial production runs at CVC's
Fremont, California, Rochester, New York and Alexandria, Virginia research and
demonstration facilities. CVC believes that its marketing efforts are enhanced
by the technical expertise of its


                                       36
<PAGE>

engineers who also provide customer process support and participate in industry
forums, conferences and user groups.



    CVC generally warrants its new systems for 15 months from the date of
shipment. CVC generally warrants to an original purchaser of its new systems
that the products and parts manufactured or assembled by CVC and the application
software supplied will be free from defects in materials and workmanship under
normal use. Installation is included in the price of the system. CVC's field
service engineers provide customers with call-out repair and maintenance
services for a fee. Customers may also enter into repair and maintenance service
contracts covering CVC's systems. For a fee, CVC trains its customers' service
engineers to perform routine services, and, in addition, CVC provides its
customers with 24-hour a day, seven day a week, telephone consultation services.
CVC also has customer support centers located in New York, California, Texas,
Minnesota, Virginia, Northern Ireland and Japan.



RESEARCH AND DEVELOPMENT



    The data storage and semiconductor manufacturing industries are
characterized by rapid technological change and requirements for new product
introductions and enhancements. CVC's ability to remain competitive in this
market will depend in part upon its ability to develop new and enhanced systems
and to introduce these systems at competitive prices and on a timely and
cost-effective basis. Accordingly, CVC devotes a significant portion of its
personnel and financial resources to research and development programs and seeks
to maintain close relationships with its customers to remain responsive to their
equipment needs. CVC continuously conducts research and development efforts in
existing products to extend performance and process capabilities as well as on
next generation products.



    In the data storage market, CVC has recently developed and introduced
capabilities that allow precise measurement and testing functions to take place
in a process module without disrupting the production process and without
disturbing the tightly controlled vacuum environment. CVC has also developed a
magnetic orientation device to achieve more accurate and programmable
characteristics of magnetic thin films. In the area of advanced interconnect
technologies, CVC has been developing leading-edge metal-organic chemical vapor
deposition barrier and copper metallization processes for high-performance
semiconductor interconnect applications. CVC operates process development and
applications engineering facilities in New York, California, Virginia and Texas
with process and metrology capabilities for data storage thin film recording
head and semiconductor technologies.



    As of September 30, 1999, CVC had 103 full-time employees dedicated to its
research and development programs. In fiscal 1997, 1998 and 1999, CVC expended
$9.1 million, $12.6 million and $12.6 million on these programs, constituting
15%, 19% and 15% of revenues during those periods, respectively. Research and
development expenditures consist primarily of salaries, project materials and
other costs associated with CVC's ongoing research and development efforts. CVC
expects in future years that research and development expenditures will continue
to represent a substantial percentage of revenues. CVC augments its internal
technology development efforts by licensing technology from others and
establishing strategic research and development relationships with universities
and various major customers.



    Trade, industry standards and development consortia, such as SEMI, SEMATECH
and SEMI/ SEMATECH, help to define the methods, measurement parameters,
manufacturing requirements and specifications influencing commercial
transactions within the data storage and semiconductor industry. Christine
Whitman, the chief executive officer of CVC, serves on the Board of Directors of
SEMI/ SEMATECH. CVC believes that its involvement with these organizations has
helped to ensure that CVC's new products conform to industry standards and
emerging requirements.


                                       37
<PAGE>
MANUFACTURING


    CVC's manufacturing activities consist primarily of assembling and testing
components and subassemblies which are acquired from third party suppliers and
then integrated by CVC into finished systems. The manufacturing operations are
conducted in CVC's 90,000 square foot facility in Rochester, New York and its
32,000 square foot facility in Alexandria, Virginia. As of September 30, 1999,
CVC had 168 full-time employees dedicated to its manufacturing efforts. CVC
manufactures its systems in controlled clean environments which are similar to
the clean rooms used by data storage and semiconductor manufacturers. All final
assembly and systems tests are performed within CVC's manufacturing facilities.
Quality control of suppliers is maintained through incoming verification of
components, in-process inspection during equipment assembly and final inspection
and operation of all manufactured equipment prior to shipment. CVC's customers
frequently participate in systems testing during the final assembly and
inspection process.



    CVC's Rochester and Fremont facilities are ISO 9001 certified. CVC believes
that ISO 9001 certification, a quality assurance model for companies that
design, produce, install and inspect items as part of their businesses, offers
CVC a competitive advantage over competitors that are not ISO 9001 certified
and, in some cases, is a condition of doing business with its customers.


    CVC procures components and subassemblies included in its products from a
limited group of suppliers and occasionally from a single source. CVC does not
maintain long-term supply contracts with its key suppliers but believes that
alternative suppliers could be found if necessary.

COMPETITION

    The data storage and semiconductor manufacturing equipment industries are
highly competitive. A substantial investment is required to install and
integrate capital equipment into a data storage or semiconductor production
line. CVC believes that once a device manufacturer has selected a particular
supplier's capital equipment, that manufacturer generally relies upon that
supplier's equipment for the specific production line application and, to the
extent possible, subsequent generations of similar systems. Accordingly, it may
be extremely difficult to achieve significant sales to a particular customer
once another supplier's manufacturing equipment has been selected by that
customer, unless there are compelling reasons to do so, such as significant
performance or cost advantages. Increased competitive pressure could lead to
lower prices for CVC's products, thereby adversely affecting CVC's operating
results.


    In the data storage market, CVC's current competitors include Balzers
Process Systems, Nordiko and Veeco Instruments. In the semiconductor market,
CVC's competitors include Applied Materials, Balzers Process Systems and
Novellus. Some of CVC's competitors have substantially greater financial
resources, more extensive engineering, manufacturing, marketing and customer
service and support capabilities, larger installed bases of semiconductor
capital equipment and broader semiconductor process equipment offerings as well
as greater name recognition than CVC.


    CVC believes that its ability to compete in the data storage and
semiconductor manufacturing equipment markets depends on a number of factors,
including:

    - the ability to develop and introduce new products rapidly

    - product and technology innovation

    - product quality and reliability

    - product performance

    - breadth of its product line

    - price

                                       38
<PAGE>
    - technical service and support

    - adequacy of manufacturing quality and capacity and sources of raw
      materials

    - efficiency of production

    - delivery capabilities

    - protection of CVC's products by intellectual property laws


CVC believes it competes favorably in the data storage and semiconductor
manufacturing markets based on its multiple processing capabilities, customer
support and the cost of ownership of its equipment.


    CVC expects its competitors in the data storage and semiconductor process
equipment industries to continue to improve the design and performance of their
current systems and processes and to introduce new systems and processes with
improved price and performance characteristics.

PATENTS AND OTHER INTELLECTUAL PROPERTY


    CVC relies on a combination of patent, copyright, trademark and trade secret
laws and non-disclosure agreements to protect its proprietary process and
equipment technology. Although CVC believes that its patents and its other
intellectual property rights may have significant value, CVC also believes that
due to the rapid technological changes that characterize the data storage and
semiconductor equipment industries, the innovative skills, technical expertise
and know-how of its personnel may be more important than patent protection or
similar rights.



    As of September 30, 1999, CVC had obtained 17 issued U.S. patents, had
received notices of allowance on four U.S. patent applications and had 37 U.S.
patent applications pending. CVC has also obtained two foreign patents from the
United Kingdom and had 18 foreign patent applications pending on its behalf as
of that date. In addition, in connection with the acquisition of Commonwealth
Scientific Corporation, CVC has licensed and been assigned rights to several
jointly-owned patents but there can be no assurance that such licensed and
assigned rights are sufficiently broad for current or contemplated uses.



    CVC holds patents which it believes to be material to its business covering
the components used for physical vapor deposition for the data storage
marketplace and rapid thermal processing. These patents have durations of not
less than eleven years. Through its acquisition of Commonwealth, CVC also holds
patents covering ion beam processing with durations of not less than eleven
years. In addition, CVC holds exclusive licenses to ion source technology
obtained in the acquisition of Commonwealth, which extend to the term of the
underlying patents, varying in length from five to eleven years.



    The data storage and semiconductor industries are characterized by frequent
litigation regarding patent and other intellectual property rights. Although CVC
is not aware of any pending or threatened patent litigation involving it, there
can be no assurance that third parties will not assert claims against CVC with
respect to existing or future products or technologies. In the event of
litigation to determine the validity of any third-party claims, that litigation,
whether or not determined in favor of CVC, could result in significant expense
to CVC and divert the efforts of CVC's technical and management personnel from
productive tasks. In the event of an adverse ruling in such litigation, CVC
might be required to discontinue the use of processes, cease the manufacture,
use and sale of infringing products, expend significant resources to develop
non-infringing technology, or obtain licenses to the infringing technology. In
the event of a successful claim against CVC and CVC's failure to develop or
license a substitute technology at a reasonable cost, CVC's business could be
harmed.


                                       39
<PAGE>

    CVC cannot give any assurance that its pending patent applications will be
approved, that any patents will provide it with competitive advantages or will
not be challenged by third parties, or that the patents of others will not have
an negative impact on CVC's business. CVC cannot give any assurance that others
will not independently develop similar products, duplicate its products or, if
patents are issued to CVC, design around these patents. CVC also relies upon
trade secret protection and employee and third-party nondisclosure agreements to
protect its confidential and proprietary information. Despite these efforts, CVC
cannot give any assurance that others will not independently develop
substantially equivalent proprietary information and techniques or otherwise
gain access to its trade secrets or disclose such technology or that CVC can
meaningfully protect its trade secrets.


EMPLOYEES


    As of September 30, 1999, CVC had a total of 394 full-time employees at all
of its locations, consisting of 168 in manufacturing, 103 in research and
development, 29 in marketing and sales, 53 in customer service and support, 35
in administration and 6 in facilities maintenance.



    As of September 30, 1999, 47 employees at CVC's site in Rochester, New York
were members of Local 342 of the International Union of Electronic, Electrical,
Salaried, Machine & Furniture Workers union and covered by a collective
bargaining agreement scheduled to expire in October, 2001. CVC believes that its
relations with its employees, and the bargaining unit which represents the Local
342 members, are good.


FACILITIES


    CVC's principal office is located in Rochester, New York, and consists of
90,000 square feet used for manufacturing, research and development and
administration. CVC entered into a financing agreement with the County of Monroe
Industrial Development Agency in 1974 under which this agency's bond proceeds
were used to purchase the land and construct the Rochester facility for lease to
CVC. On September 29, 1997, CVC entered into an amended lease agreement with the
County of Monroe Industrial Development Agency that extended the term of the
original lease from the year 2000 to December 31, 2007. Upon the expiration of
this amended lease, CVC is obligated to purchase the Rochester facility from
this agency for nominal consideration.



    As part of its acquisition of Commonwealth Scientific Corporation in
May 1999, CVC obtained two operating facilities. These facilities are located in
Alexandria, Virginia. The principal administrative office is in an owned
building which is approximately 22,000 square feet. The manufacturing and
engineering functions are located in a separate leased facility of approximately
32,000 square feet. This facility is leased under two separate leases for
approximately 28,000 square feet and 4,250 square feet of contiguous space. The
leases on this facility are scheduled to expire on January 31, 2000 and
September 14, 2001.



    In addition, CVC leases 14,400 square feet in Fremont, California, for
research and process development, product engineering and as a base for regional
sales and field service for the West Coast of the United States and 3,400 square
feet in Dallas, Texas, for engineering, equipment design, process development,
sales and customer support. CVC also leases space in Minneapolis, Minnesota,
Japan, Northern Ireland, Singapore and Taiwan for sales and customer support.
Although CVC believes that its current facilities are adequate to meet its
current requirements for the near term, it may seek to lease or acquire
additional facilities in the future.


LEGAL PROCEEDINGS

    In the ordinary course of business, CVC may be involved in legal proceedings
from time to time. As of the date of this prospectus, there are no material
legal proceedings pending against CVC.

(1) The value of the unexercised, in-the-money options on September 30, 1999 is
    based on the difference between the assumed initial public offering price of
    the common stock ($12.00 per share) and the per share option exercise price,
    multiplied by the number of shares of common stock underlying the options.


STOCK OPTION PLANS

    STOCK OPTION PROGRAM


    Until June 1996, CVC had an informal stock option program under which
selected employees were granted non-qualified options to purchase shares of
common stock. The primary purpose of this program had been to provide long-term
incentives to selected CVC employees and to further align their interests with
those of CVC. Under this program, the Compensation Committee and/or CVC's board
of directors:


    - selected the participants;

    - determined the number of shares of common stock offered to each
      participant;

    - determined the terms of the repurchase rights for each participant; and

    - determined other terms of sale.

                                       46
<PAGE>

Options granted under this informal plan generally vested over a period of
three-to-five years from the date of grant and were exercisable at the fair
market value of a share of common stock at the date of grant. Under this
program, options to purchase 1,473,840 shares of common stock have been granted,
of which options to purchase 321,333 shares of common stock have been exercised
and options to purchase 120,000 shares of common stock have been cancelled.


1996 STOCK OPTION PLAN


    CVC's 1996 Stock Option Plan was adopted by CVC's board of directors
effective June 30, 1996 under which selected employees were granted nonqualified
stock options and incentive stock options to purchase shares of common stock.
The primary purpose of this plan was to provide long-term incentives to selected
CVC employees and to further align their interests with those of CVC. Under the
plan, the Compensation Committee and/or CVC's board of directors:


    - selected the participants;

    - determined the form and number of shares of common stock offered to each
      participant;

    - determined the exercise period of each option;

    - determined the terms of the repurchase rights for each participant; and

    - determined other terms of sale.

    Options granted to employees under this plan were generally at fair market
value as of the grant date based upon valuations obtained contemporaneously from
an independent appraiser. Options granted generally vested over a period of
three-to-five years from the date of grant and were exercisable at the fair
market value of a share of common stock at the date of grant.


    As of September 30, 1999, options to purchase 582,134 shares of common stock
have been granted under this plan, of which options to purchase 16,600 shares of
common stock have been exercised and options to purchase 184,833 shares have
been cancelled. This plan was terminated as of August 30, 1999.


1997 STOCK OPTION PLAN


    CVC's 1997 Stock Option Plan was adopted by CVC's board of directors
effective October 16, 1997, under which stock options may be granted to
employees of CVC and its subsidiaries. This plan permits the grant of stock
options that qualify as incentive stock options under Section 422 of the
Internal Revenue Code and nonqualified stock options which do not so qualify.
CVC has initially authorized and reserved 1,833,333 shares of common stock for
issuance under this plan, with the number of shares authorized and reserved
being increased annually in an amount equal to 5% of the total number of shares
of common stock issued by CVC in the preceding fiscal year, with a maximum
aggregate of shares issued under this plan not to exceed 3,333,333. As of
September 30, 1999, 736,002 options had been granted. Options to purchase
185,734 shares have been cancelled and 133 shares have been exercised as of
September 30, 1999. The shares may be unissued shares or treasury shares. If an
option expires or terminates for any reason without having been exercised in
full, the unpurchased shares subject to that option will again be available for
grant under the plan.


    The Compensation Committee administers the plan. Subject to the limitations
set forth therein, the Compensation Committee has the authority to:

    - determine the persons to whom options will be granted;

    - the time at which options will be granted;

    - the number of shares subject to each option;

                                       47
<PAGE>
    - the exercise price of each option, which may not be less than the fair
      market value of the underlying common stock;

    - the time or times at which the options will become exercisable;

    - the duration of the exercise period;

    - provide for the acceleration of the exercise period of an option at any
      time prior to its termination or upon the occurrence of specified events;

    - cancel and replace stock options previously granted with new options for
      the same or a different number of shares and having a higher or lower
      exercise price; and

    - amend the terms of any outstanding stock option to provide for an exercise
      price that is higher or lower than the current exercise price.


    All officers, employees and consultants of CVC and its subsidiaries are
eligible to receive grants of stock options under this plan, as selected by the
Compensation Committee. The maximum term of options granted under this plan is
ten years from the date of grant. The maximum number of shares of common stock
that may be subject to options granted to any participant of the plan during any
one calendar year is 333,333. Options granted under the plan will generally
become vested and exercisable over a five-year period in equal annual
installments, unless the Compensation Committee specifies a different vesting
schedule. However, in the event of a change of control upon a transaction such
as a merger, consolidation, sale of all or substantially all of the assets of
CVC or a change in the composition of a majority of CVC's Board, then each
option that was not then vested prior to such event will become fully vested and
immediately exercisable unless assumed or substituted by the successor
corporation.



    All options granted under this plan are nontransferable by the optionee,
except for transfers approved by the Compensation Committee to permitted
transferees, such as immediate family members of the optionee and charitable
institutions and transfers upon the optionee's death in accordance with his will
or applicable law. In the event of an optionee's death or permanent and total
disability, outstanding options that have become exercisable will remain
exercisable for a period of one year, and the Compensation Committee will have
the discretion to determine the extent to which any unvested options shall
become vested and exercisable. In the case of any other termination of
employment, outstanding options that have previously become vested will remain
exercisable for a period of 90 days. However, all unexercised options will be
immediately forfeited by any employee who is terminated as a result of any of
the following:



    - embezzlement or misappropriation of corporate funds;



    - conviction for a felony;



    - misconduct resulting in material injury to us;



    - significant activities harmful to our reputation or the reputation of any
      of our subsidiaries;



    - a significant violation of our corporate policies;



    - willful refusal to perform, or substantial disregard of, the duties
      properly assigned to the option holder; or



    - a significant violation of any contractual, statutory or common law duty
      of loyalty to us or any of our subsidiaries.


    In addition, the exercise price of an option is payable in cash or, in the
discretion of the Compensation Committee, in common stock or a combination of
cash and common stock. An optionee must satisfy all applicable tax withholding
requirements at the time of exercise. This plan has a term of

                                       48
<PAGE>
ten years, subject to earlier termination or amendment by CVC's board of
directors, and all options granted under its plan prior to its termination
remain outstanding until they have been exercised or are terminated in
accordance with their terms. CVC's board of directors may amend this plan at any
time.

    1999 NONEMPLOYEE DIRECTOR STOCK OPTION PLAN

    CVC's board of directors has adopted the 1999 Nonemployee Director Stock
Option Plan. Under this plan, stock options are granted to each member of CVC's
board of directors who is not an employee of CVC. See "--Director Committees and
Compensation" and "--Director Compensation."


    ASSUMPTION OF COMMONWEALTH STOCK OPTIONS



    In connection with the closing of the acquisition of Commonwealth Scientific
Corporation, all outstanding options to purchase shares of Commonwealth as of
the closing were assumed by CVC. These non-qualified options are governed by
stand alone agreements with each respective optionee. As of September 30, 1999,
options to purchase an aggregate of 270,697 shares of common stock are held by
former optionees of Commonwealth.


PENSION PLAN


    CVC maintains a defined benefit retirement plan for its employees which
provides retirement benefits based upon a formula that takes into account the
employees' compensation and length of service with CVC, as well as benefits
employees may be entitled to receive under prior retirement plans of CVC. This
plan was frozen effective September 30, 1991 and no further benefits will be
accrued under it. Mr. Christopher Mann will receive $157.68 and Ms. Christine
Whitman will receive $394.28, each on a monthly basis, commencing at retirement
at attainment of age 65.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION


    The current members of the Compensation Committee are Messrs. Fink, Holmes
and Kingsley. None of these directors was at any time during the fiscal year
ended September 30, 1999, nor at any other time within the past five years, an
officer or employee of CVC. No executive officer of CVC serves as a member of a
board of directors or compensation committee of any entity which has one or more
executive officers serving as a member of CVC's board of directors or its
Compensation Committee.


AGREEMENTS WITH EMPLOYEES


    CVC has entered into severance agreements with Ms. Whitman, Messrs.
DiCataldo, Mann, Kellogg, Prozeller and Sowers and Drs. Moslehi, Chicotka and
Nocerino. These agreements provide that these employees will serve CVC in their
offices for a term of three years, with automatic one-year renewals, subject to
earlier termination as provided for in the these agreements. These agreements
set forth the following minimum base salary during the term of the particular
agreement for the following employees: (1) Ms. Whitman - $168,000;
(2) Mr. Chicotka - $127,688; (3) Mr. DiCataldo - $140,369;
(4) Mr. Kellogg - $142,000; (5) Mr. Mann - $124,162;
(6) Mr. Moslehi - $142,771; (7) Mr. Nocerino -  $220,000;
(8) Mr. Prozeller - $110,000; and (9) Mr. Sowers - $120,000. These amounts are
subject to possible increase at the sole discretion of the Compensation
Committee. Each employee is also eligible to receive, at the sole discretion of
the Compensation Committee, an annual bonus based on the contribution of the
employee towards achievement of the annual business goals of CVC. Under these
agreements, the employees are entitled to participate in the employee benefit
plans of CVC and are eligible for the grant of stock options, in the sole
discretion of the Compensation Committee.



    In addition, these agreements provide that the employee is entitled to a
lump-sum cash severance payment in the following circumstances:


                                       49
<PAGE>

    - upon a termination by CVC of the employee without cause; and



    - upon a termination by the employee of his employment with CVC, within six
      months immediately following an acquisition, merger, reorganization of CVC
      or other similar transaction or event.



This lump-sum severance payment is equal to the employee's base salary as in
effect immediately prior to termination multiplied by a number of months
(24 months for Ms. Whitman, 18 months for Mr. DiCataldo, 12 months for Drs.
Moslehi, Chicotka, Nocerino and Messrs. Mann, Kellogg, Prozeller and Sowers) and
then discounted to present value from the dates such payments would otherwise
have been made.



    Upon an acquisition, merger, reorganization or other similar transaction or
event, all options to purchase shares of common stock held by the employees that
were not then vested will become fully and immediately vested and exercisable,
unless provision has been made for (1) continuation of any such CVC option plan
and/or the assumption of such options by a successor corporation or (2) the
substitution for such options of new options covering the stock of a successor
corporation, with appropriate adjustments. An employee terminated after any of
these types of transactions or events will retain the right to exercise any
options to purchase shares of common stock for 12 months following the date of
such termination or, if earlier, the expiration of the original term of the
option.



    These agreements include restrictive covenants for the benefit of CVC
relating to non-disclosure by the employee of CVC's confidential business
information and CVC's right to inventions and technical improvements of the
employee.

                              CERTAIN TRANSACTIONS

    Advent International Group is a principal stockholder of CVC. Mr. Kingsley,
a director of CVC, is a Managing Director of Advent.


    Seagate Technology is a principal stockholder of CVC, as well as a major
customer. Mr. Waite, a director of CVC, is an officer of Seagate Technology.



    In December 1998, CVC sold an aggregate of 100,000 shares of Series C
Convertible Preferred Stock for a price of $10.00 per share and a warrant to
purchase an aggregate of 200,000 shares of common stock to entities affiliated
with Advent International Corporation in a private placement. The Series C
Convertible Preferred Stock is automatically converted into 1,016,260 shares of
common stock, as well as 100,000 shares of Series D Redeemable Preferred Stock
upon consummation of this offering. The Series D Redeemable Preferred Stock
will, in turn, be redeemed by CVC upon the consummation of this offering for a
redemption price of $10.0 million. The warrant will be terminated upon
consummation of this offering. See "Description of Capital Stock."



    Also, in connection with that transaction, CVC entered into an Amended and
Restated Registration Rights Agreement with Advent, Seagate Technology, Nikko
Tecno and executive officers and stockholders of CVC who are parties to this
agreement. Such agreement grants demand and piggy-back registration rights to
Seagate Technology and Advent with respect to shares of common stock issuable
upon conversion of all outstanding shares of the Series B and Series C Senior
Convertible Redeemable Preferred Stock, and also grants piggy-back registration
rights to the executive officers and stockholders of CVC who are parties to this
agreement. See "Description of Capital Stock--Registration Rights." In addition,
CVC entered into an Amended and Restated Stockholders' Agreement with Advent,
Seagate Technology, Nikko Tecno and the executive officers and stockholders of
CVC who are parties to this agreement providing for voting and pre-emptive
rights with respect to the acquisition and sale of shares by CVC and certain
matters affecting corporate governance. These rights will terminate when the
Series A, Series B and Series C Senior Convertible Redeemable Preferred Stock
are converted into common stock upon the consummation of this offering.



    As part of CVC's acquisition of Commonwealth in May 1999, CVC entered into a
consulting agreement with George R. Thompson, Jr., the former Chief Executive
Officer of Commonwealth and a current director of CVC. Under the terms of this
consulting agreement, CVC is obligated to pay Mr. Thompson an aggregate amount
of $525,000 over the three-year period following the acquisition, as
consideration for consulting services provided by him to CVC. In addition,
Mr. Thompson is entitled to benefits, such as an automobile allowance and health
insurance coverage. This consulting agreement may be terminated by Mr. Thompson
for any reason at any time and by the Company in the following circumstances:



    - if Mr. Thompson (1) materially breaches his obligations under a
      non-competition agreement; (2) is convicted of a felony or any offense
      involving misappropriation of money; or (3) willfully fails or refuses to
      perform his duties under this agreement or



    - upon Mr. Thompson's death.



    Nikko Tecno, a Japanese corporation, is a principal stockholder and a
distributor of CVC's products in Japan. Mr. Miyanishi, a director of CVC, is the
President and Chief Executive Officer of Nikko Tecno. CVC borrowed from Nikko
Tecno $1.5 million in November 1990 and $1.0 million in December 1991 under two
unsecured notes that required quarterly interest payments calculated at an
annual rate of 9%. The principal of the $1.0 million note was paid in October
1997. The principal of the $1.5 million note was paid in January 1999. See Notes
to Consolidated Financial Statements.



    Christine Whitman, CVC's Chairman, President and Chief Executive Officer
currently serves as a director of M&T Bank, with whom CVC has outstanding credit
agreements.



    With respect to all of the transactions listed above, CVC believes that the
terms of these transactions were, at the time entered into, no less favorable
than CVC could have obtained with
non-affiliated parties.

                          DESCRIPTION OF CAPITAL STOCK

AUTHORIZED STOCK

    Upon the completion of this offering, the authorized capital stock of CVC
will consist of 50,000,000 shares of common stock, par value $0.01 per share,
and 5,000,000 shares of new preferred stock, par value $0.01 per share.

COMMON STOCK


    Assuming conversion of all outstanding Series A, Series B and Series C
Convertible Preferred Stock, at September 30, 1999 there were 8,492,707 shares
of common stock issued and outstanding held by approximately 66 stockholders of
record. Holders of common stock are entitled to one vote for each share held of
record on any matters voted upon by stockholders and do not have any cumulative
voting rights. Subject to preferences that may be applicable to any outstanding
preferred stock, holders of common stock are entitled to receive ratably such
dividends as may be declared by CVC's board of directors out of funds legally
available therefor. In the event of a liquidation, dissolution or winding up of
CVC, holders of common stock are entitled to share ratably in all assets
remaining after payment of liabilities and the liquidation preferences of any
outstanding preferred stock.


    Holders of common stock have no preemptive rights and no right to convert
their common stock into any other securities. There are no redemption or sinking
fund provisions applicable to the common stock. All outstanding shares of common
stock are, and all shares of common stock to be outstanding upon completion of
the offering will be, validly issued, fully paid and nonassessable. The rights,
preferences and privileges of holders of common stock are subject to, and may be
adversely affected by, the rights of the holders of shares of any series of
preferred stock which CVC may designate and issue in the future.

PREFERRED STOCK


    As of September 30, 1999, 1,685 shares of Series A Convertible Preferred
Stock, 60,492 shares of Series B Convertible Preferred Stock, 100,000 shares of
Series C Convertible Preferred Stock and no shares of Series D Redeemable
Preferred Stock were issued and outstanding. Simultaneously with the closing of
this offering, the outstanding shares of Series A Convertible Preferred Stock
will automatically be converted into an aggregate of 2,696,000 shares of common
stock and the Series B Convertible Preferred Stock will automatically be
converted into 2,419,680 shares of common stock. At the same time, the Series C
Convertible Preferred Stock will automatically be converted into 1,016,260
shares of common stock and 100,000 shares of Series D Redeemable Preferred
Stock. The Series D Redeemable Preferred Stock will, in turn, be redeemed by CVC
upon the consummation of this offering for a redemption price of $10.0 million.


    Upon the closing of the offering, the conversion of the outstanding
Series A, Series B and Series C Convertible Preferred Stock, the redemption of
the Series D Redeemable Preferred Stock and the filing of an Amended and
Restated Certificate of Incorporation of CVC removing the designation of those
series, CVC's Certificate of Incorporation will authorize the issuance of up to
5,000,000 shares of new preferred stock, and none of those shares will be
outstanding or designated into any series. Under the terms of the Certificate of
Incorporation, CVC's board of directors is authorized, subject to any
limitations prescribed by law, without further stockholder approval, to issue
such shares of preferred stock in one or more series. Each such series of
preferred stock shall have such rights, preferences, privileges and
restrictions, including voting rights, dividend rights, conversion rights,
redemption privileges and liquidation preferences, as shall be determined by
CVC's board of directors.

    The purpose of authorizing CVC's board of directors to issue preferred stock
and determine its rights and preferences is to eliminate delays associated with
a stockholder vote on specific issuances.

                                       55
<PAGE>
The issuance of preferred stock, while providing desirable flexibility in
connection with possible acquisitions and other corporate purposes, could have
the effect of making it more difficult for a third party to acquire, or of
discouraging a third party from acquiring, a majority of the outstanding voting
stock of CVC. CVC has no present plans to issue any shares of preferred stock.

REGISTRATION RIGHTS


    Upon consummation of this offering, the holders of 7,218,197 shares of
common stock will be entitled to rights with respect to the registration of
these shares under the Securities Act. These registration rights have been
waived with respect to the offering. Under the terms of an agreement between CVC
and the holders of the shares eligible for registration, if CVC proposes to
register any of its securities under the Securities Act, either for its own
account or the account of other security holders exercising registration rights,
these holders are entitled to notice of registration and are entitled to include
their eligible shares in the offering, provided that the managing underwriters
have the right to limit the number of these shares included in the registration.



    Holders of 3,435,940 shares of the shares eligible for registration may also
require CVC to file a registration statement under the Securities Act at its
expense with respect to these securities, and CVC is required to use its best
efforts to effect that registration, subject to, among other things, the right
of CVC not to effect any registration within six months following this offering.
Further, stockholders may require CVC to file additional registration statements
on Form S-3 when that form becomes available to CVC. All expenses incurred in
connection with such registrations must be borne by CVC, other than underwriting
discounts and commissions.


WARRANTS

    CVC has issued a warrant to Seagate Technology to purchase 19,769 shares of
Series B Convertible Preferred Stock at an exercise price of $223.17 per share
of Series B Convertible Preferred Stock during the seven-year period commencing
on May 22, 1995, the date this warrant was issued. Upon the consummation of this
offering, this warrant will become exercisable for 790,760 shares of common
stock at an exercise price of $5.58 per share of common stock.

    CVC has issued warrants to Advent to purchase an aggregate of 133,333 shares
of common stock at an exercise price of $15.00 per share during the four-year
period commencing on December 1, 2001. This warrant, however, will terminate
upon the consummation of this offering.

LIMITATIONS ON DIRECTOR LIABILITY


    CVC's Certificate of Incorporation provides that, to the fullest extent
permitted by the Delaware General Corporation Law, none of its directors will be
personally liable to CVC or its stockholders for monetary damages.
Section 102(b)(7) of the Delaware General Corporation Law currently provides
that a director's liability for breach of fiduciary duty to a corporation may be
eliminated, except for liability:


    - for any breach of the director's duty of loyalty to the corporation or its
      stockholders;

    - for acts or omissions not in good faith or which involve intentional
      misconduct or a knowing violation of law;

    - under Section 174 of the Delaware General Corporation Law, for unlawful
      dividends or unlawful stock repurchases or redemptions; and

    - for any transaction from which the director derives an improper personal
      benefit.

    Any amendment to these provisions of the Delaware General Corporation Law
will automatically be incorporated by reference into CVC's Certificate of
Incorporation without any vote on the part of its stockholders unless otherwise
required, including this provision in CVC's Amended and Restated

                                       56
<PAGE>
Certificate. These provisions may, however, discourage or deter stockholders or
management from bringing a lawsuit against directors for a breach of their
fiduciary duties, even though such an action, if successful, might otherwise
benefit us and our stockholders.


    CVC's By-laws provide that CVC will indemnify its directors and officers to
the fullest extent permitted by Delaware law. Generally, CVC is required to
indemnify our directors and officers for all:


    - judgments;

    - fines;

    - settlements;

    - legal fees; and

    - other expenses incurred in connection with pending or threatened legal
      proceedings because of the director's or officer's position with CVC.

SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW

    CVC is subject to the provisions of Section 203 of the Delaware General
Corporation Law. Under Section 203, business combinations between a Delaware
corporation whose stock generally is publicly traded or held of record by more
than 2,000 stockholders and an interested stockholder are generally prohibited
for a three-year period following the date that such a stockholder became an
interested stockholder, unless:

    - the corporation has elected in its original certificate of incorporation
      not to be governed by Section 203. CVC did not make this election;


    - the business combination was approved by the board of directors of the
      corporation before the other party to the business combination became an
      interested stockholder;


    - upon consummation of the transaction that made it an interested
      stockholder, the interested stockholder owned at least 85% of the voting
      stock of the corporation outstanding at the commencement of the
      transaction, excluding voting stock owned by directors who are also
      officers or held in employee benefit plans in which the employees do not
      have a confidential right to tender or vote stock held by the plan; or

    - the business combination was approved by the board of directors of the
      corporation and ratified by two-thirds of the voting stock not owned by
      the interested stockholder.

    The three-year prohibition also does not apply to some business combinations
proposed by an interested stockholder following the announcement or notification
of an extraordinary transaction involving the corporation and a person who had
not been an interested stockholder during the previous three years or who became
an interested stockholder with the approval of the majority of the corporation's
directors.

    The term "business combination" is defined generally under Section 203 to
include mergers or consolidations between a Delaware corporation and an
interested stockholder, transactions with an interested stockholder involving
the assets or stock of the corporation or its majority-owned subsidiaries and
transactions which increase an interested stockholder's percentage ownership of
stock. The term "interested stockholder" is defined generally under Section 203
as a stockholder who, together with affiliates and associates, owns or within
three years prior did own 15% or more of a Delaware corporation's voting stock.
Section 203 could prohibit or delay a merger, takeover or other change in
control of CVC and therefore could discourage attempts to acquire CVC.


TRANSFER AGENT AND REGISTRAR



    The transfer agent and registrar for the common stock will be BankBoston,
N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE


    Upon completion of the offering, CVC will have 11,492,707 shares of common
stock outstanding. Of these shares, the 3,500,000 shares of common stock sold in
the offering will be freely tradable without restriction under the Securities
Act. However, any shares purchased by "affiliates" of CVC, as that term is
defined in Rule 144 under the Securities Act, generally may be sold only in
compliance with the limitations of Rule 144 described below. Affiliates include
directors, officers and holders of 10% or greater of the total outstanding
shares of common stock.


SALES OF RESTRICTED SECURITIES


    The remaining shares of common stock outstanding upon completion of the
offering are deemed "restricted securities" under Rule 144. Of the restricted
securities, up to 1,168,737 shares will be eligible for sale in the public
market after the offering pursuant to Rule 144(k) under the Securities Act;
1,167,409 of these shares are subject to the 180-day lock-up agreements
described below, but will be eligible for sale in the public market immediately
upon the closing of the offering. Of the remaining restricted securities
outstanding, 4,702,873 shares will be eligible for resale under Rule 144
commencing 90 days after the date of this prospectus; all of these shares are
subject to the 180-day lock-up agreements.



    In general, under Rule 144 as currently in effect, a holder of restricted
securities who beneficially owns shares that were not acquired from CVC or an
affiliate of CVC within the previous year would be entitled to sell within any
three-month period a number of shares that does not exceed the greater of one
percent of the then outstanding shares of common stock (approximately 114,773
shares immediately after the offering) or the average weekly trading volume of
the common stock in the over-the-counter market during the four calendar weeks
preceding the date on which notice of the sale is filed with the Securities and
Exchange Commission. Sales of restricted securities under Rule 144 are subject
to manner of sale provisions, notice requirements and the availability of
current public information about CVC. A person who is not deemed an affiliate of
CVC at any time during the three months preceding a sale, and who beneficially
owns shares that were not acquired from CVC or an affiliate within the previous
two years, is entitled to sell such shares under Rule 144(k) without regard to
volume limitations, manner of sale provisions, notice requirements or the
availability of current public information concerning CVC.


    Any employee, officer or director of or consultant to CVC who received his
or her shares pursuant to a written compensatory plan or contract is entitled to
rely on the resale provisions of Rule 701, which, beginning 90 days after the
date of this prospectus, permit persons, other than affiliates, to sell their
Rule 701 shares without having to comply with the public-information, holding
period, volume limitation or notice provisions of Rule 144. Affiliates can sell
their Rule 701 shares without having to comply with Rule 144's one-year
holding-period restrictions, but must otherwise comply with its volume
limitations and manner of sale provisions.

OPTIONS


    Upon completion of the offering, 1,901,379 shares of common stock issuable
upon exercise of stock options will become eligible for sale in the public
market subject to compliance with Rule 701 beginning 90 days after the offering;
1,758,730 of these shares underlying these options are subject to the 180-day
lock-up agreements. An additional 1,283,065 shares of common stock are available
for future grants under CVC's stock option plans.


    CVC intends to file one or more registration statements on Form S-8 under
the Securities Act to register all shares of common stock subject to outstanding
stock options and common stock issuable pursuant to CVC's stock option plans
that do not qualify for an exemption under Rule 701 from the registration
requirements of the Securities Act. CVC has agreed with the Underwriters not to
file these

                                       58
<PAGE>
registration statements earlier than 180 days following the date of this
prospectus, and any such registration statements are expected to become
effective upon filing. Shares covered by these registration statements will
thereupon be eligible for sale in the public markets, subject to the lock-up
agreements, to the extent applicable.

EFFECT OF SALES OF SHARES

    No prediction can be made as to the effect, if any, that future sales of
shares of common stock or the availability of shares for future sale will have
on the prevailing market price for the common stock. Sales of substantial
amounts of common stock, or the perception that such sales could occur, could
adversely affect prevailing market prices for the common stock and could impair
CVC's future ability to raise capital through an offering of equity securities.

    The underwriters will purchase the shares pursuant to an underwriting
agreement with CVC and the selling stockholders. The underwriters will pay CVC
and the selling stockholders the public offering price less the underwriting
discount specified on the cover page of this prospectus. CVC estimates that its
expenses for this offering will be $       . Certain conditions contained in the
underwriting agreement must be satisfied before the underwriters are required to
purchase the shares, including the delivery of legal opinions by legal counsel.
The underwriters will purchase either all of the shares or none of them.



    The underwriters have advised CVC and the selling stockholders that they
will offer the shares directly to the public initially at the public offering
price and to selected dealers, who may include underwriters, at the public
offering price less a selling concession not to exceed $               per
share. The underwriters may allow, and these dealers may reallow, a concession
not to exceed $           per share to certain brokers and dealers. After the
initial offering of the shares the underwriters may change the public offering
price and other selling terms.



    The following table shows the per share and total public offering price,

underwriters and the proceeds before expenses to CVC and the selling
stockholders. This information is presented assuming either no exercise or full
exercise by the underwriters of their over-allotment option.

    The underwriters will offer the shares subject to prior sale, withdrawal,
cancellation or modification of offer of the shares without notice, and to their
receipt and acceptance of the shares. The underwriters may reject any order to
purchase shares.

    The selling stockholders have granted the underwriters an option,
exercisable not later than 30 days after the date of this prospectus, to
purchase up to 525,000 additional shares at the public offering price less the
underwriting discount specified on the cover page of this prospectus. To the
extent that the underwriters exercise this option, each of the underwriters will
have a firm commitment, subject to conditions, to purchase approximately the
same percentage thereof that the number of shares to be purchased by it shown in
the above table bears to each underwriter's initial purchase commitment, and CVC
and the selling stockholders will be obligated to sell such shares to the
underwriters. The underwriters may exercise such option only to cover
over-allotments.

    Each of the officers and directors of CVC, and certain stockholders of CVC,
including the selling stockholders, have agreed not to offer, sell, pledge or
otherwise dispose of any shares of common stock, directly or indirectly, or
engage in hedging transactions with respect to the common stock, for a period of
180 days after the date of this prospectus, without the prior written consent of
Lehman Brothers Inc. Stockholders who have agreed to this lock-up arrangement
hold an aggregate of       shares of common stock and options to purchase an
aggregate of       shares of common stock. CVC has agreed not to sell or
otherwise dispose of any shares of common stock for a period of 180 days,
subject to exceptions. Lehman Brothers Inc. may, in its sole discretion and at
any time without notice, release all or any portion of the shares subject to
such lock-up agreements. See "Shares Eligible for Future Sale."



    Prior to this offering, there has been no public market for the shares of
common stock. The initial public offering price will be negotiated by the
representatives of the underwriters, CVC and representatives of the selling
stockholders. The underwriters will consider, among other things and in addition
to prevailing market conditions, CVC's historical performance and capital
structure, estimates of business potential and earning prospects, an overall
assessment of CVC's management and the consideration of the above factors in
relation to market valuation of companies in related businesses.



    At CVC's request, the underwriters have reserved for sale, at the initial
public offering price, up to             of the shares of common stock offered
in this offering for CVC's directors, officers, employees and related persons.
The number of shares of common stock available for sale to the general public
will be reduced to the extent these individuals purchase the reserved shares.
Any reserved shares which are not so purchased will be offered by the
underwriters to the general public on the same basis as the other shares offered
hereby.


    Application has been made to have the common stock approved for quotation on
the Nasdaq National Market under the symbol "CVCI."


    CVC and the selling stockholders have agreed to indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act, and
to contribute, under specified circumstances, to payments that the underwriters
may be required to make in respect thereof.



    Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters and
certain selling group members to bid for and purchase shares of common stock. As
an exception to these rules, the underwriters are permitted to engage in
transactions that stabilize the price of the common stock. Such transactions may
consist of bids or purchases for the purposes of pegging, fixing or maintaining
the price of the common stock.



    If the underwriters create a short position in the common stock in
connection with this offering, i.e., they sell more shares than are set forth on
the cover page of this prospectus, the underwriters may reduce that short
position by purchasing common stock in the open market. The underwriters also
may elect to reduce any short position by exercising all or part of their
over-allotment option.


    The underwriters also may impose a penalty bid on certain underwriters and
selling group members. This means that if the underwriters purchase shares of
common stock in the open market to reduce the underwriters' short position or to
stabilize the price of the common stock, they may reclaim the amount of the
selling concession from the underwriters and selling group members who sold
those shares as part of this offering.


    In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it was to discourage resales of the security by purchasers in an
offering.

    Neither CVC nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the common stock. In addition, neither
CVC nor any of the underwriters makes any representation that the underwriters
will engage in such transactions or that such transactions, once commenced, will
not be discontinued without notice.

    Any offers in Canada will be made only pursuant to an exemption from the

of shares of common stock to any accounts over which they exercise discretionary
authority in excess of 5% of the shares offered by them.

                       REPORT OF INDEPENDENT ACCOUNTANTS



To Board of Directors and
Stockholders of CVC, Inc.



    The stock split described in Note 1 to the consolidated financial statements
has not been consummated at October 21, 1999. When it has been consummated, we
will be in a position to furnish the following report:



        "In our opinion, the accompanying consolidated balance sheets and the
    related consolidated statements of operations, stockholders' equity and cash
    flows present fairly, in all material respects, the financial position of
    CVC, Inc. (the "Company") and its subsidiaries at September 30, 1999 and
    1998, and the results of their operations and their cash flows for each of
    the three years in the period ended September 30, 1999 in conformity with
    generally accepted accounting principles. These financial statements are the
    responsibility of the Company's management; our responsibility is to express
    an opinion on these financial statements based on our audits. We conducted
    our audits of these statements in accordance with generally accepted
    auditing standards which require that we plan and perform the audit to
    obtain reasonable assurance about whether the financial statements are free
    of material misstatement. An audit includes examining, on a test basis,
    evidence supporting the amounts and disclosures in the financial statements,
    assessing the accounting principles used and significant estimates made by
    management, and evaluating the overall financial statement presentation. We
    believe that our audits provide a reasonable basis for the opinion expressed
    above."

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1--NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES


PRINCIPLES OF CONSOLIDATION AND NATURE OF OPERATION



    The consolidated financial statements of CVC, Inc. and subsidiaries (CVC or
the Company) include the consolidated accounts of CVC, Inc., CVC Products Inc.,
Commonwealth Scientific Corporation, since acquisition on May 10, 1999, and CVC
Process Solutions, Inc. CVC is a leading worldwide supplier of fabrication
equipment providing thin film process solutions for the manufacture of magnetic
recording heads and advanced semiconductor devices for computers and
communications systems. The Company maintains offices in Rochester, New York;
Alexandria, Virginia; Fremont, California; Garland, Texas; Minneapolis,
Minnesota; Japan and Northern Ireland.



    All significant intercompany balances and transactions have been eliminated
in consolidation.


UNAUDITED PRO FORMA BALANCE SHEET


    The Company's Series A and Series B Convertible Preferred Stock
automatically convert into common stock and the Company's Series C Convertible
Preferred Stock automatically converts into common stock and Series D Redeemable
Preferred Stock concurrent with the closing of an initial public offering
(Note 10). Accordingly, the unaudited pro forma balance sheet has been presented
on a basis to give effect to the automatic conversion of such stock as of the
closing date of the initial public offering which for pro forma purposes is
assumed to occur as of September 30, 1999.


USE OF ESTIMATES


    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at year-end as well as the
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.


CONCENTRATION OF CREDIT RISK


    Financial instruments which potentially expose the Company to significant
concentrations of credit risk consist principally of bank deposits, temporary
investments, accounts receivable (including related party receivables--Note 12)
and accrued expenses. Cash is placed primarily in high quality short-term
interest bearing financial instruments.


    The Company performs ongoing credit evaluations of its customers' financial
condition and the Company maintains an allowance for uncollectible accounts
receivable based upon the expected collectibility of all accounts receivable.

FAIR VALUE OF FINANCIAL INSTRUMENTS


    The carrying amount of the Company's financial instruments, including cash
and cash equivalents, accounts receivable, accounts payable and accrued
expenses, approximates their fair value at September 30, 1998 and 1999, as the
maturities of these instruments are all short term. Due to differences in the
stated interest rates on certain short and long-term debt obligations compared
to prevailing rates, the fair value of these instruments does vary from their
carrying amounts; however, such differences are immaterial.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

NOTE 1--NATURE OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)
REVENUE RECOGNITION


    Revenue from the sale of equipment is recognized upon shipment. Provisions
for estimated product warranty and installation costs are recorded at the time
revenue is recognized. The Company generally warrants its new systems for
15 months from the date of shipment. Such warranties provide that new systems
are free from defects in materials and workmanship under normal use.



    Amounts received from customers prior to product shipment are classified as
advances from customers.


CASH AND CASH EQUIVALENTS


    Cash and cash equivalents consist of highly liquid debt instruments with
original maturities of three months or less.


INVENTORIES

    Inventories, which include materials, labor and overhead, are recorded at
the lower of cost, determined by the first-in, first-out method, or market
value. The Company provides inventory reserves for excess, obsolete or
slow-moving inventory based on changes in customer demand, technology
developments, and other economic factors.

PROPERTY, PLANT AND EQUIPMENT


    Property, plant and equipment are stated at cost. Depreciation is provided
on a straight-line basis over the estimated useful lives of 3 to 10 years for
equipment, furniture and fixtures and 40 years for buildings. Building
improvements are depreciated over the shorter of 10 years or the remaining life
of the building or the useful life of the improvement. Maintenance and repairs
are expensed as incurred. Improvements which extend the useful life of property,
plant and equipment are capitalized. Upon retirement or disposal of an asset,
the asset and the related accumulated depreciation are eliminated from the
accounts, with any gains or losses from sale recorded in the statement of
operations.


CAPITALIZED SOFTWARE COSTS


    The Company capitalizes the costs associated with purchased software for
resale and subsequently amortizes such costs on a units-of-production basis over
their estimated remaining economic life, generally 3 years. These amounts, which
are included in other assets, are reported at the lower of the unamortized cost
or net realizable value and are immaterial.



ASSET IMPAIRMENT



    The Company regularly assesses all of its long-lived assets for impairment
when events or circumstances indicate, in accordance with Statement of Financial
Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of." The assessment
is accomplished by comparing the estimated undiscounted future cash flows of the
asset grouping with the respective carrying amount as of the date of assessment.
Should aggregate future cash flows be less than the carrying value of the
assets, a write-down would be

required, measured by the difference between the carrying value of the assets
and the discounted future cash flows.


RESEARCH AND DEVELOPMENT

    Research and development costs are expensed as incurred.

INCOME TAXES

    The Company accounts for income taxes using the asset and liability approach
which requires recognition of deferred tax liabilities and assets for the
expected future tax consequences of temporary differences between the financial
statement carrying amounts and the tax basis of such assets and liabilities.


    The asset and liability method utilizes enacted statutory tax rates in
effect for the year in which the temporary differences are expected to reverse
and gives immediate effect to changes in income tax rates upon enactment.
Deferred tax assets are recognized, net of any valuation allowance, for
deductible temporary differences and net operating loss and tax credit
carryforwards.



NEW ACCOUNTING STANDARDS



    Effective October 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130 (SFAS 130), "Reporting Comprehensive Income", which
establishes new rules for the reporting and display of comprehensive income and
its components; however, the adoption had no impact on the Company's net income
or stockholders' equity. SFAS 130 requires changes to the minimum pension
liability, to be included in other comprehensive income. Prior year financial
statements have been reclassified to conform to the requirements of SFAS 130.



    In April 1998, the Accounting Standards Executive Committee issued Statement
of Position (SOP) 98-5, "Reporting on the Costs of Start-Up Activities."
Start-up activities are defined broadly as those one-time activities relating to
opening a new facility, introducing a new product or service, conducting
business in a new territory, conducting business with a new class of customer,
commencing some new operation or organizing a new entity. Under SOP 98-5, the
cost of start-up activities should be expensed as incurred. SOP 98-5 is
effective for the Company's fiscal year 2000 financial statements and the
Company does not expect its adoption to have a material effect on the Company's
financial condition or results of operations.



    In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The new standard
establishes accounting and reporting standards for derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. SFAS No. 133 is effective for all quarters of fiscal years
beginning after June 15, 2000. The Company does not expect SFAS No. 133 to have
a material effect on the Company's financial condition or results of operations.

STOCK SPLITS


    On October 14, 1997, the Company declared a 3-for-1 stock split in the form
of a stock dividend to stockholders of record at the close of business on
October 31, 1997. This stock split increased the number of common shares
outstanding by 849,260. All references in the consolidated financial statements
referring to share prices, conversion rates, per share amounts, stock option
plans and common shares issued and outstanding have been adjusted retroactively
for the 3-for-1 stock split.


    On August 30, 1999, the Company declared a 2-for-3 reverse stock split
effective for stockholders of record upon the closing of an initial public
offering. This reverse stock split decreased the number of common shares
outstanding by 1,172,688. All references in the consolidated financial
statements referring to share prices, conversion rates, per share amounts, stock
option plans and common shares issued and/or outstanding have been adjusted
retroactively for the 2-for-3 reverse stock split.



NOTE 2--ACQUISITION



    On May 10, 1999, the Company acquired Commonwealth Scientific Corporation
(Commonwealth), a Virginia based company which offers ion beam modules and
systems which provide ion beam etching, deposition and diamond-line carbon (DLC)
processes and ion beam sources for research and development (R&D) and original
equipment manufacturer customers. The purchase price of $8,498,000 was comprised
of the issuance of 1,268,799 shares of the Company's common stock, exchanged and
assumed options in Commonwealth for options to purchase 286,228 shares of the
Company's common stock, and related acquisition costs. The issuance of the
Company's stock was recorded at fair market value, and the assumed options were
recorded at fair market value using the Black-Scholes option pricing model. The
acquisition was accounted for using the purchase method of accounting. The
purchase price was allocated as follows (in thousands):

</TABLE>


    The net tangible assets includes a write-up of Commonwealth's property to
fair market value by $600,000 and the recognition of a restructuring liability
approximating $550,000. Approximately $140,000 of the restructuring liability
relates to severance costs associated with the reduction of Commonwealth's
workforce by approximately 20%, or 29 employees. The reduction of the workforce
and the payment of termination benefits was completed by September 30, 1999.
Approximately $410,000 of the restructuring liability relates to existing lease
obligations or cancellation penalties associated with facilities which will be
exited. Lease payments will be made through fiscal 2000. At September 30, 1999,
approximately $200,000 has been charged against the restructuring liability. The
Company believes that the amounts remaining under the restructuring liability
are adequate to cover the remaining lease obligations.

NOTE 2--ACQUISITION (CONTINUED)

    The purchased in-process R&D includes the value of products in the
development stage, which have not reached technological feasibility and for
which there is no alternative future use. In accordance with applicable
accounting rules, purchased in-process R&D is required to be expensed.
Accordingly, the amount of $1,174,000 was expensed in the third quarter of
fiscal 1999.


    The company used independent professional appraisal consultants to assess
and allocate value to the acquired in-process R&D. The allocated value was
determined using the income approach, which involves estimating the discounted
after-tax cash flows attributable to projects based on the projects' stage of
completion.



    A discount rate of 35% was applied to the projects' cash flows and there
were no material changes from historical pricing, margins, and expense levels.
Management believes that the assumptions used in the forecasts were reasonable
at the time of the business combination. No assurance can be given, however,
that the underlying assumptions used to estimate expected project sales,
development costs, or profitability will be realized as estimated. For these
reasons, actual results may vary from the projected results.



    Estimated net cash inflows from the acquired in-process technology are
projected to commence in fiscal 2001.



    The amortization periods of intangible assets related to workforce in place,
current technology and goodwill are seven years, five years and seven years,
respectively.



    The operating results of Commonwealth have been included in the Company's
consolidated statement of operations from the date of acquisition. The unaudited
pro forma results below assume the acquisition occurred on October 1, 1997 (in

NOTE 6--NOTES PAYABLE AND LONG-TERM DEBT


    In August 1974, the Company entered into an agreement with a local
government agency under which the agency's bond proceeds of $2,400,000 were used
to purchase land and construct an operating facility for lease to the Company.
The industrial revenue bond obligation required monthly payments of principal
and interest at 8% (approximately $19,000 in total). In September 1997, the
Company refinanced the remaining principal of the industrial revenue bond with
the proceeds of a new mortgage credit facility with a principal of $2,000,000.
The lease term extends to December 31, 2007, at which time title to the property
passes, upon payment of nominal consideration by the Company. The new mortgage
credit facility requires monthly payments of approximately $16,000 through
October 1, 2007, calculated based upon an amortization period of twenty years.
In addition, on October 1, 2007, the Company will pay a final installment equal
to the outstanding principal and interest on the credit facility based upon the
actual term of this facility which is ten years. The interest rate on $500,000
of the mortgage credit facility is 5.29% until October 1, 1999 after which the
rate increases to 8.29% through September 30, 2002, consistent with the interest
rate on $1,500,000 of the credit facility. Beginning October 1, 2002, the
Company will likely elect to pay interest on the remaining principal at the then
prime rate plus one-half percent, or a rate equal to 225 basis points above the
yield on U.S. treasury bonds. The obligation is secured by certain land and
buildings with a net book value of $2,386,000 at September 30, 1999.



    In November 1990, the Company borrowed $1,500,000 from a company whose
president is a director and shareholder of the Company. In December 1991, the
Company borrowed an additional $1,000,000 from this company. The borrowings were
evidenced by notes, which were unsecured and required quarterly interest
payments at 9%. The $1,000,000 note was paid in full in November 1997 and the
$1,500,000 note was paid in full in January 1999. Interest expense on these
notes totaled $225,000, $138,000 and $34,000 in 1997, 1998 and 1999,
respectively.



    In September 1996, the Company borrowed $3,000,000 from a commercial bank.
The five year term loan requires monthly payments of principal and interest at
prime plus 1/2% through October 1, 2001. The obligation is secured by certain
equipment and capital assets.


    In April 1998, the Company borrowed $8,000,000 from a commercial bank. The
seven year term loan requires monthly payments of principal and interest at
8.39% until April 2005. The obligation is secured by certain personal property
and other intangibles of the Company including patents, patent applications and
trademarks.


    In connection with the acquisition of Commonwealth, the Company assumed a
$1,214,000 unsecured note payable to a third party. The 18-month note requires
payments of principal and interest at 8% until October 2000.

    The Company also has a $15,000,000 bank line of credit at September 30, 1999
which allows for maximum borrowings based on certain financial criteria.
Allowable borrowings based on this criteria at September 30, 1999 were
$13,819,000. Borrowings under the agreements are at an interest rate of prime.
There was approximately $10,679,000 outstanding under the line of credit at
September 30, 1999.



    The Company also has available an equipment line of credit at September 30,
1999 which allows for maximum borrowings of $3,000,000 based on certain
financial criteria. Borrowings under the agreement are at an interest rate of
prime. There were no amounts outstanding under the line of credit at
September 30, 1999.



    The debt agreements contain financial covenants requiring the Company to
maintain certain debt to equity, capital, and current ratios, as well as certain
customer order, income, and operating cash flow levels. The agreement also
imposes limitations on the incurrence of additional debt. The Company was in
compliance with all covenants at September 30, 1998 and 1999.

    The differences between income taxes (benefit) at the U.S. statutory rate
and the effective rate for the years ended September 30, 1997, 1998 and 1999 are

</TABLE>



    During 1998 and 1999, the valuation allowance, which relates to net
operating loss carryforwards and state investment credits, was reduced by
$53,000 and $130,000, respectively, due to the increased likelihood the benefits
will be recognized. As a result of the acquisition of Commonwealth, in 1999, a
number of permanent items were recorded by the Company and the valuation
allowance increased by the assumed amount of $449,000.



    The net operating tax loss carryforwards of approximately $820,000 expire at
various times through 2019.

NOTE 8--EMPLOYEE BENEFIT PLANS


    The Company maintains a 401(k) profit sharing plan covering substantially
all employees who meet certain age and length of service requirements. The
Company contributes a percentage of the amount of salary deferral contributions
made by each participating employee. Any additional contributions by the Company
are discretionary. The amounts charged to expense related to this plan were
approximately $92,000, $222,000 and $278,000 in fiscal years 1997, 1998 and
1999, respectively.



    The Company had a noncontributory defined benefit pension plan. The Company
froze this plan effective September 30, 1991 at which time all benefits became
fully vested. Benefits were based on historical compensation levels and years of
service. The Company's funding policy is to contribute annually an amount, based
on actuarial computations, which would satisfy the Internal Revenue Service's
funding standards. Approximately $122,000 and $381,000 is included in other
liabilities at September 30, 1998 and 1999, respectively, for accrued pension
costs. Further, the Company has recorded an additional minimum pension liability
representing the excess of the unfunded accumulated benefit obligation over plan
assets. The additional minimum liability was charged to stockholders' equity,
net of income taxes.


NOTE 9--POSTRETIREMENT HEALTH CARE BENEFITS


    The Company provides health care and life insurance benefits to certain
retired hourly employees as well as health care benefits to salaried retirees
employed prior to December 31, 1996. As permitted under SFAS No. 106,
"Employers' Accounting for Postretirement Benefits Other Than Pensions," the
Company has elected to amortize the unfunded accrued postretirement benefit
obligation at adoption over a 20-year period.

NOTE 9--POSTRETIREMENT HEALTH CARE BENEFITS (CONTINUED)
    The funding policy for retiree health care and life insurance benefits is
generally to pay covered expenses as they are incurred.


    The actuarial calculation assumes a health care average inflation rate of
9.5% in 1999 and grades down uniformly to 4.5% in 2010 and remains level
thereafter. The health care cost trend rate has an effect on the amounts
reported. Increasing the health care inflation rate by 1% would increase the
September 30, 1999 accumulated postretirement benefit obligation by $190,000,
and the 1999 service cost plus interest by $55,000. Decreasing the health care
inflation rate by 1% would decrease the September 30, 1999 accumulated
postretirement benefit obligation by $155,000, and the 1999 service cost plus
interest by $42,000. The weighted average discount rate used in determining the
accumulated postretirement benefit obligation was 7.50%.


NOTE 10--STOCKHOLDERS' EQUITY

    In 1990, the Company issued 1,685 shares of 8% Series A Non-Cumulative
Convertible Preferred Stock (Series A Preferred Stock). The Series A Preferred
Stock is convertible at any time at the option of the holder into common stock
at the rate of 1,600 shares of common stock for each share of Series A Preferred
Stock. The liquidation preference of each share of Series A Preferred Stock is
$1,000 and all declared but unpaid dividends. Preferred voting rights are one
vote for each share of common stock into which the preferred shares may be
converted. The Series A Preferred Stock will be automatically converted to
2,696,000 shares of common stock upon the closing of an initial public offering
with a price per share in excess of $12.50 and aggregate gross proceeds of
$10,000,000.

    In May 1995, the Company issued 60,492 shares of Series B Non-Cumulative
Convertible Preferred Stock (Series B Preferred Stock). The Series B Preferred
Stock is convertible at any time at the option of the holder into common stock
at the rate of 40 shares of common stock for each share of Series B Preferred
Stock. Preferred voting rights are one vote for each share of common stock into
which the preferred shares may be converted. The Series B Preferred Stock will
be automatically converted to 2,419,680 shares of common stock upon the closing
of an initial public offering with a price per share in excess of $12.50 and
aggregate gross proceeds of $10,000,000.

    In connection with the issuance of Series B Preferred Stock, the holder was
granted a seven-year warrant to purchase 19,769 shares of Series B Preferred
Stock at an exercise price of $223.17 per share of Series B Preferred Stock.
Expenses directly associated with this issuance of approximately $645,000 were
netted against proceeds. The liquidation preference of each share of Series B
Preferred Stock is $148.78 and all declared but unpaid dividends. Upon the
automatic conversion of the Company's then outstanding shares of Series B
Preferred Stock coincident to the closing of an initial public offering, the
Company will execute a new warrant to the holder, with terms similar to the
original Series B warrant, to purchase 790,760 shares of the Company's Common
Stock at an exercise price of $5.58 per share in lieu of Series B Preferred
Stock.


    In December 1998, the Company issued 100,000 shares of Series C
Non-Cumulative Convertible Preferred Stock (Series C Preferred Stock). The
Series C Preferred Stock is convertible at any time at the option of the holder
into common stock at the rate of 10.1626 shares of common stock for each share
of Series C Preferred Stock. Preferred voting rights are one vote for each share
of common stock into which the preferred shares may be converted. The Series C
Preferred Stock will be automatically converted to 1,016,260 shares of common
stock as well as 100,000 shares of Series D Redeemable

NOTE 10--STOCKHOLDERS' EQUITY (CONTINUED)
Preferred Stock upon the closing of an initial public offering with a price per
share in excess of $12.50 and aggregate gross proceeds of $10,000,000.


    In connection with the issuance of Series C Preferred Stock, the holder was
granted a seven-year warrant to purchase an aggregate of 133,333 shares of
common stock at $15 per share. The warrant cannot be exercised until
December 10, 2001. Additionally, the warrant will no longer be exercisable upon
an initial public offering. A fair value of $14,000 was assigned to this warrant
at the time of purchase.


    On October 14, 1997, the Company filed a Certificate of Amendment to the
Certificate of Incorporation which increased total authorized common stock to
50,000,000 shares, $.01 par value, and total authorized preferred stock to
502,500 shares, $.01 par value.


    The Company grants options to key employees to purchase its common stock,
generally at fair market value as of the date of grant, based upon valuations
obtained contemporaneously from an independent appraiser. Such valuations have
been obtained by the Company, primarily on a quarterly basis, since June 30,
1995. Options generally vest over a 3 to 5 year period and expire after
10 years from the date of grant.



    In October 1997, the Board of Directors and stockholders approved a new
stock option plan, the 1997 Stock Option Plan (the "Plan"), under which options
may be granted to employees of the Company. The Plan permits the grant of stock
options that qualify as incentive stock options under Section 422 of the
Internal Revenue Code, and nonqualified stock options, which do not so qualify.
In 1999, the Board of Directors amended the plan, which increased the amount of
shares authorized under the plan by 1,000,000 shares. Additionally, the Board of
Directors has authorized the Company to increase the number of shares available
for issuance under the plan by an amount equal to five percent of the total
number of shares of common stock issued by the Company during the preceding
fiscal year. As of September 30, 1998 and 1999, the Company has authorized and
reserved 833,333 and 1,833,333 shares, respectively, of common stock for
issuance under the Plan; and, options available for grant under the Plan were
523,333 and 1,283,065 shares, respectively.



    During fiscal 1997 and 1998, approximately 203,333 and 160,000 options,
respectively, were granted to employees at an amount which was less than the
fair market value as of the grant date. Accordingly, the Company recorded
unamortized deferred compensation expense for such options which vest over a
3 to 5 year period. Compensation expense is being amortized over the vesting
period and unamortized compensation expense has been recorded as a reduction in
stockholders' equity. During fiscal 1997, 1998 and 1999, compensation expense
recognized in the statements of operations approximated $7,000, $111,000 and
$105,000, respectively.



    Under the provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation," the Company has elected to continue to account for its employee
stock plans in accordance with the provisions of APB Opinion No. 25 which
requires compensation costs to be recognized based on the intrinsic value of
options at the grant date. Had compensation cost for the Company's stock option
plan been determined based on the fair value at the grant date for awards in
fiscal years 1997, 1998 and 1999

the Black-Scholes option pricing model (minimum value method) with the weighted
average assumptions of risk free interest rates (based on anticipated length of
time until exercise) ranging from 4.24% to 5.65% and expected lives of 3 to 5
years.

NOTE 11--EARNINGS PER SHARE


    Basic earnings per share (EPS) is computed by dividing income available to
common shareholders by the weighted average number of common shares actually
outstanding for the period. Diluted EPS reflects the potential dilution that
could occur if securities or other contracts to issue common stock were
exercised or converted into common stock or resulted in the issuance of common
stock that then shared in the earnings of the Company.


    The following table illustrates the calculation of both basic and diluted
EPS for the years ended September 30, 1997, 1998 and 1999 (in thousands):

    At September 30, 1998, the Company had borrowings of $1,500,000 from a
company whose president is a director and shareholder of the Company (Note 6).



    Seagate Technology (Seagate), which provides products for storage,
retrieval, and management of data on computer and data communications systems,
is the Company's largest customer and a significant stockholder. Revenues, cost
of goods sold, accounts receivable and unearned revenue associated with

the consolidated statements of operations and balance sheets. Management
believes the selling prices and sales terms of such transactions are
substantially consistent with those for unrelated third parties.

also a shareholder, was elected to the Board of Directors of the Company's
Financial Institution, M&T Bank.



NOTE 13--SEGMENT DATA, SIGNIFICANT CUSTOMERS AND GEOGRAPHIC INFORMATION



    The Company adopted the provisions of SFAS No. 131, "Disclosures About

proceeds from the initial public offering. During the fourth quarter of fiscal
1998, the Company withdrew its intent to complete the public offering and,
accordingly, these costs were charged against current period earnings.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and the Board of Directors of
Commonwealth Scientific Corporation:

    We have audited the accompanying balance sheets of Commonwealth Scientific
Corporation (the "Company," a Virginia corporation), a wholly owned subsidiary
of CVC, Inc. (the "Parent," a Delaware corporation), as of March 31, 1998 and
1999, and the related statements of operations, stockholders' equity, and cash
flows for each of the three years in the period ended March 31, 1999. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Commonwealth Scientific
Corporation as of March 31, 1998 and 1999, and the results of its operations and
its cash flows for each of the three years in the period ended March 31, 1999,
in conformity with generally accepted accounting principles.

               NOTES TO FINANCIAL STATEMENTS AS OF MARCH 31, 1999

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

BUSINESS

    Commonwealth Scientific Corporation (the "Company"), a wholly owned
subsidiary of CVC, Inc. (the "Parent"), is engaged in the development,
production, sale, service, and repair of precision equipment for the purpose of
etching or deposition at submicron levels by means of ion beam technology. The
Company was acquired by CVC, Inc., on May 10, 1999 (see Note 13). The Parent is
committed to the necessary support of the operations and capital requirements of
the Company.

USE OF ESTIMATES

    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Significant estimates made by management include the adequacy
of reserves for doubtful accounts, obsolete and excess inventories, and customer
warranty obligations. Actual results could differ from those estimates.

REVENUE RECOGNITION

    Revenue is recognized when all significant risks of ownership are
transferred and all significant related acts of performance are completed, which
is generally upon shipment of products.

SIGNIFICANT CUSTOMER

    During fiscal year 1997, 28, 14, and 11 percent of net sales were derived
from three customers. In fiscal year 1999, the Company had one customer who
accounted for 32 percent of net sales. No other customer accounted for more than
10 percent of net sales.

DEPRECIATION AND AMORTIZATION

    Depreciation and amortization are provided using the straight-line method
for financial reporting purposes over the following estimated useful lives:

<TABLE>
<S>                                                           <C>
Building and improvements...................................  5 to 31.5 years
Manufacturing and test equipment............................  5 years
Office furniture and fixtures...............................  5 to 7 years
</TABLE>

    Repair and maintenance costs are charged to expense when incurred. Renewals
and betterments that significantly increase the useful life of the related asset
are capitalized. Leasehold improvements are amortized over the expected useful
life or the lease term, whichever is shorter.

    The Company implemented Statement of Financial Accounting Standards ("SFAS")
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of, "during 1996. As of March 31, 1999, management
determined there had been no impairment of long-lived assets as defined by SFAS
No. 121.

    The Company's anticipated gross revenues, the remaining estimated lives of

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
competitive pressures in any of the Company's individual markets. As a result,
the carrying amount of long-lived assets could be reduced materially in the near
term.

RESEARCH AND DEVELOPMENT COSTS

    Research and development costs are recognized as expenses in the period
incurred.

WARRANTY SERVICES

    The Company recognizes the estimated cost of warranty obligations at the
time the related products are sold. A one-year warranty on materials and
workmanship is offered on products sold.

DEPOSITS ON SALES CONTRACTS

    The Company negotiates progress payments on projects that require
significant engineering development and/or several months to complete.

CASH AND CASH EQUIVALENTS

    For financial reporting purposes, the Company considers demand deposits and
all highly liquid investments with a maturity of three months or less to be cash
and cash equivalents. As of March 31, 1998 and 1999, cash equivalents consisted
principally of investments in overnight reverse repurchase agreements and
commercial paper. The Company maintains bank accounts with federally insured
financial institutions. At times, balances may exceed insured limits.

2. INVENTORIES:

    Inventories are stated at the lower of cost (determined on a first-in,
first-out basis) or market. Work in progress and finished goods include
provisions for direct labor and manufacturing overhead. Inventories were
composed of the following as of March 31, 1998 and 1999:

    The Company's products are subject to technological change and changes in
the Company's competitive market. Management has provided reserves for excess
and obsolete inventories. It is possible that new product launches could result
in unforeseen changes in inventory requirements for which no reserve has been
provided.

4. LINES OF CREDIT:

    The Company has a bank line of credit, subject to annual approval, which
provides for borrowings up to the lesser of $1,800,000 or an amount equal to
70 percent of eligible accounts receivable that have been outstanding not more
than 90 days. Amounts borrowed under the line are payable on demand. Interest
accrues at the bank's prime rate plus 0.5 percent (8.25 percent at March 31,
1999) and is payable monthly. The amount borrowed on the line of credit was
approximately $1,385,000 and $693,000 at March 31, 1998 and 1999, respectively.

    The Company has two bank lines of credit for inventory that provide for
borrowings up to $3,500,000. Amounts borrowed under these lines of credit are
payable on due dates between June 2001 and January 2002. Interest accrues at the
bank's prime rate plus 1.0 percent (8.75 percent at March 31, 1999) and is
payable monthly. The amount borrowed on the line of credit was $1,200,000 and
$2,700,000 at March 31, 1998 and 1999, respectively.

    All lines of credit discussed above are collateralized by the same assets as
the notes payable to a bank discussed in Note 5. One of the inventory lines of
credit is personally guaranteed by the president of the Company in an amount up
to $2,000,000. The remaining amounts outstanding under the lines of credit,
together with the long-term obligations described below, are guaranteed by the
president of the Company in an amount up to $1,000,000. As further described in
Note 13, all amounts outstanding under these lines of credit were paid in full
subsequent to March 31, 1999.

</TABLE>

    The bank notes and lines of credit are secured by all the Company's present
and future fixtures, equipment, supplies, inventory, work in progress, accounts
receivable and contract rights, and a first lien deed of trust on the Company's
real property and improvements. These borrowings are personally guaranteed by
the president of the Company in an amount up to $1,000,000 pursuant to the
guarantee on the lines of credit described in Note 4. According to the terms of
the loan agreements, the Company must satisfy various covenants, including a
debt to equity ratio of less than 2 to 1, a current ratio of greater than 1 to
1, a net worth of at least $7,500,000, and debt service coverage of greater than
1 to 1 among other restrictions. The Company was not in compliance with the
tangible net worth and debt service coverage ratios, consignments, sale and
transfer of assets, and capital expenditure and lease obligation covenants as of
March 31, 1999. The Company received a waiver from the bank for these covenant
violations in April 1999.

    Future minimum principal payments under long-term obligations are as
follows:

5. LONG-TERM OBLIGATIONS: (CONTINUED)
    As further described in Note 13, all amounts due under these bank loans were
paid in full subsequent to March 31, 1999.

6. STOCK AND STOCK OPTIONS:

    During fiscal year 1985, the Company's stockholders approved a stock option
plan (the "Stock Option Plan") for key employees, officers, and directors of the
Company for 100,000 shares of stock, of which 76,150 shares were granted as of
March 31, 1999. The Company's stock option plan expired in fiscal year 1994. The
options outstanding under the Stock Option Plan are fully vested two years after
the grant date and are exercisable for three years.

    Options issued after fiscal year 1994 but prior to March 1999 were issued
after the expiration of the Stock Option Plan and are classified as nonqualified
for tax purposes. The terms and conditions of these options are identical to
those options issued under the Stock Option Plan described above.

    The options issued in March 1999 were also issued after the expiration of
the Stock Option Plan and are also classified as nonqualified for tax purposes.
These options vest immediately and are exercisable for five years.

    The following table summarizes the Company's stock option activity for each
of the three years in the period ended March 31, 1999:

</TABLE>

    As of March 31, 1998 and 1999, 22,250 and 42,354 options, respectively, are
exercisable. The weighted-average remaining life for options outstanding at
March 31, 1999, was approximately four years.

    The Financial Accounting Standards Board ("FASB") Statement of Financial
Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation," defines a fair value based method of accounting for an employee
stock option or similar equity instrument. Under the fair value based method,
compensation cost is measured at the grant date based on the value of the award
and is recognized over the service period.

6. STOCK AND STOCK OPTIONS: (CONTINUED)
    SFAS No. 123 allows an entity to continue to use the intrinsic value method
as defined by Accounting Principles Board ("APB") Opinion No. 25, "Accounting
for Stock Issued to Employees," and management has elected to do so. Under the
intrinsic value method, compensation cost is the excess, if any, of the quoted
market price of the stock at grant date or other measurement date over the
amount an employee must pay to acquire the stock. The Company has elected to
continue to apply APB Opinion No. 25 to its stock-based compensation awards to
employees. Entities electing to remain with the accounting in APB Opinion
No. 25 must make pro forma disclosures of net income and earnings per share as
if the fair value based method of accounting had been applied. Accordingly, net
(loss) income would be as follows for each of the three years in the period
ended March 31, 1999:

1999...................................................    (2,194,299)  $(2,439,258)
</TABLE>

    The fair value of each option is estimated using the Black Scholes option
pricing model with the following assumption used for grants: no dividend yield,
no volatility, risk-free interest rate of 5.5 percent, and expected life of
5 years.

7. INCOME TAXES:

    The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes." SFAS 109 requires the determination of deferred
tax liabilities and assets based on the differences between the financial
statement and income tax basis of assets and liabilities using enacted tax rates
in effect for the year in which the differences are expected to reverse. The
measurement of a deferred tax asset is adjusted by a valuation allowance, if
necessary, to recognize tax benefits only to the extent that based on available
evidence it is more likely than not that they will be realized.

    The (benefit) provision for income taxes consists of the following:

10. RELATED PARTY:

    During 1998 and 1999, a company owned by a former officer of the Company
performed research and development activities on the Company's behalf. In
addition, the officer received royalties on sales of certain of the Company's
products. During fiscal years 1998 and 1999, the Company paid approximately
$656,000 and $894,000, respectively, under that arrangement.

11. EMPLOYEE BENEFIT PLAN:

    The Company established an employee contribution plan (the "Benefit Plan"),
effective January 1, 1987, under Section 401(k) of the Internal Revenue Code.
Any employee who has attained age 21 and has completed one year of service with
the Company is eligible to participate. Each participant may contribute amounts
to the Benefit Plan, subject to limits by the Internal Revenue Service, in
pretax contributions ranging from 1 to 15 percent of base salary. The Company
will match 50 percent of each participant's contribution up to $500 per year. At
the end of each fiscal year, the Company may contribute a percentage of its
profits to the Benefit Plan. The Company made discretionary contributions of
$50,000 and $0 to the Benefit Plan for the years ended March 31, 1998 and 1999,
respectively.

12. THE YEAR 2000 ISSUE:

    The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. The effects of the Year 2000 Issue may be
experienced before, on, or after January 1, 2000, and if not addressed, the
impact on operations and financial reporting may range from minor errors to
significant systems failure, which could affect an entity's ability to conduct
normal business operations. It is not possible to be certain that all aspects of
the Year 2000 Issue affecting an entity, including those related to the efforts
of customers, suppliers, or other third parties, will be fully resolved.

13. SUBSEQUENT EVENTS:

    On May 10, 1999, CVC, Inc., acquired all the outstanding common stock of the
Company. As consideration, CVC, Inc., gave to each holder of Company stock
6.03601 shares of its common stock for each share of Company common stock held,
subject to certain adjustments described below. The merger agreement between
CVC, Inc., CVC Acquisition Corp., Commonwealth Scientific Corporation, and
Certain Stockholders Thereof, dated April 1, 1999, provides for 975,000 shares
to be held in escrow pending determination of the final purchase price. As of
May 10, the Company adopted CVC, Inc.'s year-end of September 30, 1999. The
final purchase price is dependent upon a number of representations and
warranties, including minimum net worth requirements and tax and environmental
liability considerations.

    In May 1999, CVC, Inc., repaid the entire balance (approximately $5,700,000
of principal and accrued interest) due under the Company's lines of credit, as
well as the long-term equipment and automobile loans payable to the Company's
bank. No further obligations exist under these debt instruments.

    On April 1, 1999, the Company converted approximately $1.2 million in
accounts payable due to a creditor to an unsecured note payable, bearing
interest at 8 percent per annum. Beginning May 15, 1999, principal and interest
payments of $71,790 are payable monthly. Interest will accrue at a rate of
10 percent per annum in the event of the Company's failure to pay the amounts
due within ten days of the due date. Monthly installments shall continue until
the entire indebtedness is repaid; however, any remaining indebtedness, if not
sooner paid, shall be due and payable on October 15, 2000.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a Delaware corporation may indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or enterprise,
against expenses, judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation, and, with respect to any
criminal action or proceeding, had no cause to believe his conduct was unlawful.

    Section 145(b) of the DGCL provides that a Delaware corporation may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person acted in any of the capacities set forth above, against expenses actually
and reasonably incurred by him in connection with the defense or settlement of
such action or suit if he acted under similar standards, except that no
indemnification may be made in respect of any claim, issue or matter as to which
such person shall have been adjudged to be liable to the corporation unless and
only to the extent that the court in which such action or suit was brought shall
determine that despite the adjudication of liability, such person is fairly and
reasonably entitled to be indemnified for such expenses which the court shall
deem proper.

    Section 145 of the DGCL further provides that to the extent a director or
officer of a corporation has been successful in the defense of any action, suit
or proceeding referred to in subsections (a) and (b) or in the defense of any
claim, issue, or matter therein, he shall be indemnified against any expenses
actually and reasonably incurred by him in connection therewith; that
indemnification provided for by Section 145 shall not be deemed exclusive of any
rights to which the indemnified party may be entitled; and that the corporation
may purchase and maintain insurance on behalf of a director or officer of the
corporation against any liability asserted against him or incurred by him in any
such capacity or arising out of his status as such whether or not the
corporation would have the power to indemnify him against such liabilities under
Section 145.

                                      II-1
<PAGE>
    Section 102(b)(7) of the DGCL provides that a corporation in its original
certificate of incorporation or an amendment thereto validly approved by
stockholders may eliminate or limit personal liability of members of its board
of directors or governing body for breach of a director's fiduciary duty.
However, no such provision may eliminate or limit the liability of a director
for breaching his duty of loyalty, failing to action good faith, engaging in
intentional misconduct or knowingly violating a law, paying a dividend or
approving a stock repurchase which was illegal, or obtaining an improper
personal benefit. A provision of this type has no effect on the availability of
equitable remedies, such as injunction or rescission, for breach of fiduciary
duty. The Company's Restated Certificate of Incorporation contains such a
provision.

    The Company's Certificate of Incorporation and By-Laws provide that the
Company shall indemnify officers and directors and, to the extent permitted by
the Board of Directors, employees and agents of the Company, to the full extent
permitted by and in the manner permissible under the laws of the State of
Delaware. In addition, the By-Laws permit the Board of Directors to authorize
the Company to purchase and maintain insurance against any liability asserted
against any director, officer, employee or agent of the Company arising out of
his capacity as such.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

    During the past three years, the Registrant has issued securities to a
limited number of persons, as described below. No underwriter or underwriting
discounts or commissions were involved. There was no public offering in such
transaction and the Company believes that such transaction was exempt from the
registration requirements of the Securities Act of 1933, as amended (the
"Securities Act"), by reason of Section 4(2) thereof based on the private nature
of the transactions and the sophistication of the purchasers, all of whom had
access to information concerning the Registrant and acquired the securities for
investment and not with a view to the distribution thereof.

    The following figures give effect to a 20-1 stock split in December 1995, a
3-1 stock split in October 1997 and a 2-3 reverse stock split in
September 1999.

ITEM 17. UNDERTAKINGS

    The undersigned Registrant hereby undertakes to provide to the underwriters,
at the closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

    The undersigned Registrant hereby undertakes that:

        (1) For purposes of determining any liability under the Securities Act
    of 1933, the information omitted from the form of prospectus filed as part
    of this registration statement in reliance upon Rule 430A and contained in a
    form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
    (4) or 497(h) under the Securities Act shall be deemed to be part of this
    registration statement as of the time it was declared effective.

        (2) For the purpose of determining any liability under the Securities
    Act of 1933, each post-effective amendment that contains a form of
    prospectus shall be deemed to be a new registration statement relating to
    the securities offered therein, and the offering of such securities at the
    time shall be deemed to be the initial bona fide offering thereof.

behalf by the undersigned, thereunto duly authorized, in the City of Rochester,

directors with respect to his or her shares of stock multiplied by the number of
directors to be elected by such holder either (i) by casting all such holder's
votes for a single director or (ii) by distributing such holder's votes among

                                   CVC, INC.
                            (Pursuant to Section 242)

      CVC, Inc., a corporation organized and existing under the laws of the
State of Delaware (the "Corporation"), hereby certifies as follows:

      1. The name of the Corporation is CVC, Inc.

      2. The original Certificate of Incorporation of the Corporation was filed
with the Secretary of State of the State of Delaware on October 19, 1990. Such
certificate was amended pursuant to a Restated Certificate of Incorporation of
the Corporation filed with the Secretary of State of the State of Delaware on
May 18, 1995, which was subsequently amended pursuant to a Certificate of
Amendment filed with the Secretary of State of the State of Delaware on October
15, 1997.

      3. This Amended and Restated Certificate of Incorporation is hereby
further amended as follows:

            A. Article IV shall be deleted and replaced in its entirety with the
following:

                                   "Article IV

      (a) The Corporation is authorized to issue two classes of stock,
designated "Common Stock" and "Preferred Stock." The total number of shares
which the Corporation is authorized to issue is 50,502,500 The total number of
shares of Common Stock which the Corporation is authorized to issue is
50,000,000, par value $.01 per share. The total number of shares of Preferred
Stock which the Corporation is authorized to issue is 502,500, par value $.01
per share, of which (i) 2,500 shares, $.01 par value per share, shall be
designated "8% Non-Cumulative Convertible Preferred Stock" (the "Series A
Preferred"), (ii) 100,000 shares, $.01 par value per share, shall be designated
"Series B Non-Cumulative Convertible Preferred Stock" (the "Series B
Preferred"), (iii) 200,000 shares, $.01 par value per share, shall be designated
"Series C Senior Convertible Redeemable Preferred Stock" (the "Series C
Preferred"), and (iv) 200,000 shares, $.01 par value par share, shall be
designated "Series D Redeemable Preferred Stock" (the "Series D Preferred"). The
Series A Preferred, the Series B Preferred, the Series C Preferred and the
Series D Preferred shall collectively be referred to as the "Preferred Stock."

      The Corporation shall from time to time in accordance with the laws of the
State of Delaware increase the authorized amount of its Common Stock if at any
time the number of shares of Common Stock remaining unissued and available for
issuance shall not be sufficient to permit conversion of the Preferred Stock.
<PAGE>


      The relative rights, preferences, privileges and restrictions granted to
or imposed upon the Preferred Stock and the Common Stock or the holders thereof
are as follows:

      Section 1. Dividends. The holders of the Preferred Stock shall be entitled
to receive, when and as declared by the Board of Directors, dividends at the
rate of $80.00 per share for Series A Preferred, $11.90 per share for Series B
Preferred and $8.00 per share for Series C Preferred (in each case as adjusted
for any stock splits, stock dividends, recapitalization and the like with
respect to such shares) per annum as the Board of Directors may from time to
time determine out of funds legally available therefor. No dividends shall be
paid on the Series A Preferred during any fiscal year of the Corporation until
dividends in the total amount of $11.90 per share on the Series B Preferred
shall have been paid or declared and set apart during that fiscal year. No
dividends shall be paid on the Series A Preferred and Series B Preferred during
any fiscal year of the Corporation until dividends in the total amount of $8.00
per share on the Series C Preferred shall have been paid or declared and set
apart during that fiscal year. No dividends (other than those payable solely in
the Common Stock of the Corporation) shall be paid on any Common Stock of the
Corporation during any fiscal year of the Corporation until dividends in the
total amount of $80.00 per share of Series A Preferred, $11.90 per share of
Series B Preferred and $8.00 per share of Series C Preferred (in each case as
adjusted for any stock splits, stock dividends, recapitalization and the like
with respect to such shares) shall have been paid or declared and set apart
during that fiscal year. The right to such dividends on shares of Preferred
Stock shall not be cumulative, and no right shall accrue to holders of Preferred
Stock by reason of the fact that dividends on said shares are not declared in
any prior year.

      After payment of such dividends to the holders of the Preferred Stock, any
additional dividends declared shall be distributed among all the holders of the
Common Stock.

      Section 2. Liquidation Preference. In the event of a Liquidity Event (as
hereinafter defined), before any distribution or payment may be made with
respect to the Common Stock or any other series or class of capital stock
ranking on liquidation junior to the Preferred Stock, holders of each share of
Preferred Stock shall be entitled to be paid out of the assets of the
Corporation available for distribution to holders of the Corporation's capital
stock of all classes, whether such assets are capital, surplus, or capital
earnings, as follows:

            (a) The holders of the Series C Preferred or Series D Preferred
shall be entitled to receive, prior and in preference to any distribution of any
of the assets or surplus funds of the Corporation to the holders of the Series A
Preferred, Series B Preferred and Common Stock, by reason of their ownership of
such stock, the amount equal to the sum of (i) $100.00 per share for each share
of Series C Preferred (as adjusted for stock splits, stock dividends,
recapitalizations and the like with respect to such stock) (the "Liquidation
Cash Payment"), (ii) an amount equal to all declared, but unpaid dividends or
distributions on the Series C Preferred and (iii) if the Series C Preferred has
not been converted in accordance with Section 4(b) or 4(d), the number of shares
of
<PAGE>

Common Stock issuable upon conversion of such shares of Series C Preferred had
such Series C Preferred been converted into shares of Series D Preferred and
Common Stock immediately prior to such Liquidity Event. If the assets and funds
thus distributed among the holders of the Series C Preferred or Series D
Preferred pursuant to this Section 2(a) shall be insufficient to permit the
payment to such holders of the full aforesaid preferential amount, then the
entire assets and funds of the Corporation legally available for distribution
shall be distributed ratably among the holders of the Series C Preferred or
Series D Preferred in proportion to the preferential amount that each such
holder is otherwise entitled to receive.

            (b) The holders of the Series B Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of the Series A Preferred and
the Common Stock by reason of their ownership of such stock, the amount equal to
the sum of (i) $148.78 per share for each share of Series B Preferred (as
adjusted for stock splits, stock dividends, recapitalization and the like with
respect to such stock), and (ii) an amount equal to all declared but unpaid
dividends or distributions on the Series B Preferred. If the assets and funds
thus distributed among the holders of the Series B Preferred pursuant to this
Section 2(b) shall be insufficient to permit the payment to such holders of the
full aforesaid preferential amount, then the entire assets and funds of the
Corporation legally available for distribution shall be distributed ratably
among the holders of the Series B Preferred in proportion to the preferential
amount that each such holder is otherwise entitled to receive.

            (c) After payment has been made to the holders of the Series C
Preferred and the Series B Preferred of the full amounts to which they shall be
entitled as set forth in the first sentence of Section 2(a) and Section 2(b),
respectively, then the holders of the Series A Preferred shall be entitled to
receive the amount equal to the sum of (i) $1,000 per share for each share of
Series A Preferred then held by them (as adjusted for stock splits, stock
dividends, recapitalization and the like with respect to such stock), and (ii)
an amount equal to declared but unpaid dividends or distributions on the Series
A Preferred. If the assets and funds thus distributed among the holders of the
Series A Preferred pursuant to this Section 2(c) shall be insufficient to permit
the payment to such holders of the full aforesaid preferential amount, then the
entire assets and funds of the Corporation legally available for distribution
pursuant to this Section 2(c) shall be distributed ratably among the holders of
the Series A Preferred in proportion to the preferential amount that each such
holder is otherwise entitled to receive.

            (d) After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled as set forth in
Section 2(a) through Section 2(c) above, then the entire remaining assets and
funds of the Corporation legally available for distribution, if any, shall be
distributed on a pro rata basis on the outstanding Common Stock.

            (e) For purposes of this Section 2, the term "Liquidity Event" shall
mean any one or more of the following: (i) a liquidation, dissolution or
winding-up of the
<PAGE>

Corporation, whether voluntary or involuntary; (ii) a sale, merger,
recapitalization, reorganization or consolidation involving the Corporation, as
the result of which those persons who hold at least 50% of the voting stock of
the Corporation immediately prior to such transaction do not hold more than 50%
of the voting stock of the Corporation (or the surviving or resulting entity)
after giving effect to such transaction; or (iii) the sale of all or
substantially all of the assets of the Corporation.

            (f) Any securities to be delivered to the holders of the Preferred
Stock and Common Stock upon a merger, reorganization or sale of substantially
all the assets of the Corporation shall be valued as follows:

                  (1) if traded on a securities exchange or on the NASDAQ Stock
Market, the value shall be deemed to be the average of the closing prices of the
securities on such exchange over the ten business day period ending three (3)
business days prior to the closing of such merger, reorganization or sale;

                  (2) if actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid prices over the ten business day
period ending three (3) business days prior to the closing; and

                  (3) if there is no active public market, the value shall be
the fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of Series B
Preferred and Series C Preferred voting as a single class, provided that if the
Corporation and the holders of a majority of the outstanding shares of Series B
Preferred and Series C Preferred are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the Corporation,
but reasonably acceptable to the holders of a majority of the outstanding shares
of Series B Preferred and Series C Preferred voting as a single class.

            (g) Notwithstanding the foregoing, in the event that on or before
December 10, 1999. the Corporation shall merge or consolidate with or into any
other corporation or sell, lease or convey all or substantially all of its
property or business (a "Year 1 Transaction") and the aggregate consideration
payable to the holders of the Series C Preferred under this Section 2 as a
result of the Year 1 Transaction would be equal to or greater than the product
of(x) $200 and (y) the number of shares of Series C Preferred issued and
outstanding immediately prior to the consummation of the Year 1 Transaction (the
"Series C Return"), then the Liquidation Cash Payment may, at the option of the
Corporation, be reduced by an amount of not more than 50% thereof; provided that
the Common Stock issuable upon the conversion of the Series C Preferred in
accordance with Section 4(b) or 4(d) (as the case may be) shall be increased, if
necessary, by that number of fully paid and nonassessable shares of Common Stock
(the "Additional Liquidation Shares") such that the aggregate consideration to
be received by the holders of the Series C Preferred as a result of the Year 1
Transaction shall be no less than an amount equal to the Series C Return;
provided further, however, that the foregoing shall in no way limit the
aggregate consideration payable to the Holders of the Series C Preferred as a
result of the Year 1 Transaction to the Series C Return. The
<PAGE>

Additional Liquidation Shares and any other shares of Common Stock distributable
to the holders of the Series C Preferred as a result of a Year 1 Transaction
shall be valued at the per share value of the Year 1 Transaction.

      Section 3. Redemption.

            (a) At the individual option of each holder of shares of Series B
Preferred and Series C Preferred, the Corporation shall redeem, on December
10, 2003 (the "Redemption Date"), the number of shares of Series B Preferred and
Series C Preferred, respectively, held by such holder that is specified in a
request (the "Redemption Request") for redemption delivered to the Corporation
by the holder on or prior to December 10, 2003, with respect to the shares of
Series B Preferred, by paying in cash therefor, $148.78 per share of Series B
Preferred (as adjusted for stock splits, stock dividends, recapitalization and
the like with respect to such shares) plus all declared but unpaid dividends on
such shares and, with respect to the shares of Series C Preferred, by paying to
the holders of the shares of Series C Preferred (i) $100.00 per share of Series
C Preferred (as adjusted for stock splits, stock dividends, recapitalization and
the like with respect to such shares) ("Redemption Cash Payment"), (ii) an
amount equal to all declared, but unpaid dividends or distributions on the
Series C Preferred and (iii) by distributing to the holders of the shares of
Series C Preferred the number of shares of Common Stock issuable upon conversion
of such shares of Series C Preferred had such Series C Preferred been converted
into shares of Series D Preferred and Common Stock immediately prior to such
Redemption.

            (b) In the event of a Liquidity Event, the holders of the Series D
Preferred may, at their election, require the Corporation to redeem all (but not
less than all) of the shares of Series D Preferred held by such holders for an
aggregate amount (if all originally issued and outstanding Series C Preferred
was converted into Series D Preferred and all such shares of Series D Preferred
are then outstanding) equal to $100.00 per share (as adjusted for stock splits,
stock dividends, recapitalization and the like with respect to such shares).
Upon the occurrence of a Qualified Public Offering, the Corporation may either
(i) redeem the number of shares of Series D Preferred held by such holder (if
all originally issued and outstanding Series C Preferred was converted into
Series D Preferred and all such shares of Series D Preferred are then
outstanding) by paying in cash an aggregate amount (if all originally issued
Series C Preferred was converted into Series D Preferred and all such Series D
Preferred are then outstanding) equal to $100.00, (as adjusted for stock splits,
stock dividends, recapitalization and the like with respect to such shares), or
(ii) exchange each such share of Series D Preferred for such number of shares of
Common Stock such that at the per share offer price in connection with a
Qualified Public Offering the value of the aggregate number of shares so
delivered would (if all originally issued Class C Preferred Stock was converted
into Series D Preferred and all such shares of Series D Preferred are then
outstanding) equal to $100.00 per share of Series D Preferred (as adjusted for
stock splits, stock dividends, recapitalization and the like with respect to
such shares). "Qualified Public Offering" is defined to mean the closing of an
underwritten public offering by the Company pursuant to a registration statement
filed and declared effective under the Act covering the offer
<PAGE>

and sale of Common Stock for the account of the Company in which the aggregate
net proceeds to the Company equal at least $20,000,000 and in which the price
per share of Common Stock equals or exceeds $8.33.

            (c) At least ten (l0) but no more than twenty (20) days prior to the
Redemption Date written notice shall be mailed, first class postage prepaid, to
each holder of the Series B Preferred, Series C Preferred or the Series D
Preferred (as the case may be) which has given the Corporation a Redemption
Request at the address set forth in the Redemption Request, notifying such
holder of the place at which payment may be obtained on the Redemption Date for
the shares of Series B Preferred, Series C Preferred or the Series D Preferred
(as the case may be) specified in the Redemption Request and calling upon such
holder to surrender to the Corporation, in the manner and at the place
designated, such holder's certificate or certificates representing the shares to
be redeemed (the "Redemption Notice"). On or after the Redemption Date, each
holder of Series B Preferred, Series C Preferred or the Series D Preferred (as
the case may be) to be redeemed shall surrender to this Corporation the
certificate or certificates representing such shares, in the manner and at the
place designated in the Redemption Notice, and thereupon the Redemption Price of
such shares shall be payable to the order of the person whose name appears on
such certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled. In the event less than all the shares represented
by any such certificate are redeemed, a new certificate shall be issued
representing the unredeemed shares.

            (d) From and after the Redemption Date, unless there shall have been
a default in payment of the Redemption Price, all rights of the holders of
shares of Series B Preferred, Series C Preferred or the Series D Preferred (as
the case may be) designated for redemption in the Redemption Request as holders
of Series B Preferred, Series C Preferred or the Series D Preferred (as the case
may be) (except the right to receive the Redemption Price without interest upon
surrender of their certificate or certificates) shall cease with respect to such
shares, and such shares shall not thereafter be transferred on the books of the
Corporation or be deemed to be outstanding for any purpose whatsoever. If the
funds of the Corporation legally available for redemption of shares of Series B
Preferred, Series C Preferred or the Series D Preferred (as the case may be) on
the Redemption Date are insufficient to redeem the total number of shares of
Series B Preferred, Series C Preferred or the Series D Preferred (as the case
may be) to be redeemed on such date, those funds which are legally available
will be used to redeem the maximum possible number of such shares ratably among
the holders of such shares to be redeemed based upon their holdings of Series B
Preferred, Series C Preferred or the Series D Preferred (as the case may be).
The shares of Series B Preferred, Series C Preferred or the Series D Preferred
(as the case may be) not redeemed shall remain outstanding and entitled to all
the rights and preferences provided herein. At any time thereafter when
additional funds of the Corporation are legally available for the redemption of
shares of Series B Preferred, Series C Preferred or the Series D Preferred (as
the case may be) such funds will immediately be used to redeem the balance of
the shares which the Corporation has become obliged to redeem on any Redemption
Date, but which it has not redeemed.
<PAGE>

            (e) Notwithstanding the foregoing, in the event of a Year 1
Transaction on or before December 10, 1999, and the aggregate consideration
payable to the holders of the Series C Preferred under this Section 2 as a
result of the Year 1 Transaction would be equal to or greater than Series C
Return, then the Redemption Cash Payment may, at the option of the Corporation,
be reduced by an amount of not more than 50% thereof; provided that the Common
Stock issuable upon the conversion of the Series C Preferred in accordance with
Section 4(b) or 4(d) (as the case may be) shall be increased, if necessary, by
that number of fully paid and nonassessable shares of Common Stock (the
"Additional Redemption Shares") such that the aggregate consideration to be
received by the holders of the Series C Preferred as a result of the Year 1
Transaction shall be no less than an amount equal to the Series C Return;
provided further, however, that the foregoing shall in no way limit the
aggregate consideration payable to the Holders of the Series C Preferred as a
result of the Year 1 Transaction to the Series C Return. The Additional
Redemption Shares and any other shares of Common Stock distributable to the
holder of the Series C Preferred as a result of a Year 1 Transaction shall be
valued at the per share value of the Year 1 Transaction.

      Section 4. Conversion. The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

            (a) Right to Convert Series A Preferred and Series B Preferred. Each
share of Series A Preferred and Series B Preferred shall be convertible, at the
option of the holder thereof, at any time after the date of issuance of such
share, at the office of the Corporation or any transfer agent for such Preferred
Stock, into such number of fully paid and nonassessable shares of Common Stock,
(i) in the case of the Series A Preferred, as is determined by dividing $1,000
by the then applicable Series A Conversion Price and (ii) in the case of the
Series B Preferred, as is determined by dividing $148.78 by the then applicable
Series B Conversion Price. The price at which shares of Common Stock shall be
deliverable upon conversion of the Series A Preferred (the "Series A Conversion
Price") shall initially be $0.42 per share of Common Stock and the price at
which shares of Common Stock shall be deliverable upon conversion of the Series
B Preferred (the "Series B Conversion Price") shall initially be $2.48 per share
of Common Stock. Such initial Series A Conversion Price and Series B Conversion
Price shall be subject to adjustment as hereinafter provided.

            (b) Conversion of Series C Preferred. Each share of Series C
Preferred shall be convertible, at the option of the holder thereof, at any time
commencing after the fifth anniversary of the date of issuance of such share, at
the office of the Corporation or any transfer agent for such preferred stock
into (i) one (1) fully paid and nonassessable share of Series D Preferred Stock
and (ii) such number of fully paid and nonassessable shares of Common Stock,
which is determined by dividing the product of the number of shares of Series C
Preferred outstanding and $100.00 per share (as adjusted for stock splits, stock
dividends, recapitalization and the like with respect to such shares) by then
applicable purchase price per share of $6.56 (as adjusted in accordance with
Section 4(h) below) (the "Series C Conversion Price"), and which
<PAGE>

number of shares of Common Stock shall initially be 1,524,390. The Series C
Conversion Price shall initially be $6.56 per share of Common Stock. Any holder
of Series C Preferred who wishes to exercise such right of conversion shall give
written notice thereof to the Corporation, setting forth the number of shares
of Series C Preferred to be converted, and shall exchange with the Corporation
its certificates evidencing shares of Series C Preferred for certificates
evidencing the shares of Series D Preferred and Common Stock issuable upon
conversion thereof. Once a holder of Series C Preferred has given notice of its
intent to convert, it shall be deemed to have effected such conversion and shall
be deemed to be the record holder of the Series D Preferred Stock and Common
Stock, issuable upon such conversion; provided, however, that if such holder has
elected to convert in connection with a proposed Liquidity Event, and such
Liquidity Event is not consummated, such election to convert may be rescinded.

            (c) Automatic Conversion of Series A Preferred and Series B
Preferred. Each share of the Series A Preferred and Series B Preferred shall
automatically be converted into shares of Common Stock at the then effective
Series A Conversion Price and Series B Conversion Price as applicable,
immediately prior to the closing of a Qualified Public Offering at a price per
share (determined without regard to underwriter commissions and expenses) of not
less than Eight Dollars and Thirty-Three Cents $8.33 (as adjusted for stock
splits, stock dividends, recapitalization and the like) and aggregate gross
proceeds to the Corporation of not less than Ten Million Dollars ($10,000,000),
before deduction of underwriting discounts and commissions and registration
expenses. In the event of such an offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of such Preferred Stock shall not
be deemed to have converted such Preferred Stock until immediately prior to the
closing of such Qualified Public Offering.

            (d) Automatic Conversion of Series C Preferred. Upon the occurrence
of (i) a Liquidity Event or (ii) the closing of a Qualified Public Offering,
which is based on an equity valuation of the Company of not less than
$100,000,000, each share of Series C Preferred shall be converted immediately
prior to the Liquidity Event or Qualified Public Offering (as the case may be)
into (i) one fully paid and nonassessable (1) share of Series D Preferred and
(ii) such number of fully paid and nonassessable shares of Common Stock as
determined by dividing the product of the number of shares of Series C Preferred
outstanding and $100.00 per share (as adjusted for stock splits, stock
dividends, recapitalization and the like with respect to such shares) by the
Series C Conversion Price, which aggregate number of shares of Common Stock if
100,000 shares of such Series C Preferred were to be converted shall initially
be 1,524,390. In the event of such an offering, the person(s) entitled to
receive Common Stock issuable upon conversion of Series C Preferred shall not be
deemed to have converted such shares of Series C Preferred until immediately
prior to the closing of such Qualified Public Offering.

            (e) Conversion of Series D Preferred. Holders of shares of the
Series D Preferred shall have no right to convert such shares into shares of
Common Stock or any other series or capital stock of the Corporation.
<PAGE>

            (f) Mechanics of Conversion. No fractional shares of Common Stock
shall be issued upon conversion of the Preferred Stock. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall (after aggregating all shares into which shares of Preferred
Stock held by each holder could be converted) pay cash equal to such fraction
multiplied by the Series A Conversion Price or Series B Conversion Price, as
applicable, then in effect. Before any holder of Preferred Stock shall be
entitled to convert the same into full shares of Common Stock and to receive
certificates therefor, the holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent, and shall give written notice to the Corporation at such office
that the holder elects to convert all or any number of shares of the Preferred
Stock represented by such certificate or certificates, provided, however, that
in the event of an automatic conversion pursuant to this Section 4, the
outstanding shares of Preferred Stock shall be converted automatically without
any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered to the Corporation or its
transfer agent, and provided further, that the Corporation shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable
upon such automatic conversion unless the certificates evidencing such shares of
Preferred Stock are either delivered to the Corporation or its transfer agent as
provided above, or the holder notifies the Corporation or its transfer agent
that such certificates have been lost, stolen or destroyed and executes an
agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. The Corporation shall,
as soon as practicable after such delivery, or such agreement and
indemnification in the case of a lost certificate, issue and deliver at the
office of the Corporation or of any transfer agent, as the case may be, to such
holder of Preferred Stock, a certificate or certificates for the number of
shares of Common Stock to which the holder shall be entitled as aforesaid and a
check payable to the holder in the amount of any cash amounts payable as the
result of a conversion into a fractional share of Common Stock. Such conversion
shall not terminate the rights of the holders of the Preferred Stock or Common
Stock issuable upon conversion of the Preferred Stock to receive dividends which
have been declared with respect to the Preferred Stock prior to the date of
conversion. Except as provided above, such conversion shall be deemed to have
been made immediately prior to the close of business on the date of such
surrender of the shares of Preferred Stock to be converted, or in the case of
automatic conversion immediately prior to the close of business on the date of
closing of a Qualified Public Offering, and the person or persons entitled to
receive the shares of Common Stock issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common Stock at the close of business on such date. If the conversion is in
connection with a firm commitment Offering, the conversion may, at the option of
any holder tendering the Preferred Stock for conversion, be conditioned upon the
closing with the underwriter of the sale of securities pursuant to such
offering, in which event the person(s) entitled to receive the Common Stock
issuable upon such conversion of the Preferred Stock shall not be deemed to have
converted such Preferred Stock until immediately prior to the closing of such
sale of securities.

            (g) Series B Preferred and Series C Preferred Conversion Price
Adjustments. The Series B Conversion Price and the Series C Conversion Price
shall be subject to adjustment from time to time as follows:

                  (i) Special Definitions. For purposes of this Section 4(g),
the following definitions shall apply:

                        (1) "Options" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

                        (2) "Original Issue Date" shall mean the date on which
the first share of Series B Preferred or Series C Preferred, as applicable, was
first issued.

                        (3) "Convertible Securities" shall mean any evidences of
indebtedness, shares (other than Common Stock and Preferred Stock) or other
securities convertible into or exchangeable for Common Stock.

                        (4) "Conversion Price" shall be the Conversion Price of
the Series B Preferred or the Series C Preferred, as applicable.

                        (5) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 4(g)(iii) below, deemed
to be issued) by the Corporation after the Original Issue Date other than shares
of Common Stock issued or issuable:

                              (A) upon conversion of shares of the Preferred
Stock or the exercise or conversion of any Options outstanding on the Original
Issue Date;

                              (B) to officers, directors, employees and
consultants of the Corporation or any subsidiary thereof, pursuant to a stock
option plan, stock purchase plan or other employee stock incentive plan approved
by the Board of Directors or other stock arrangements which have been approved
by the Board of Directors;

                              (C) pursuant to any event for which adjustment has
already been made pursuant to this Section 4(g);

                              (D) as a dividend or distribution on the Preferred
Stock;

                              (E) as a dividend or distribution on the Common
Stock;
<PAGE>

                              (F) upon any subdivision or split up of Common
Stock; or

                              (G) upon any capital reorganization of the
Corporation.

                  (ii) No Adjustment of Conversion Price. No adjustment in the
Conversion Price shall be made in respect of the issuance of Additional Shares
of Common Stock unless the consideration per share for an Additional Share of
Common Stock issued or deemed to be issued by the Corporation is less than the
Conversion Price, in effect on the date of and immediately prior to such issue.

                  (iii) Deemed Issue of Additional Shares of Common Stock.
Except as provided in Section 4(g)(i)(5) above, in the event the Corporation at
any time or from time to time after the Original Issue Date shall issue any
Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such a record date shall have been fixed, as
of the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined pursuant to Section 4(g)(v) below) of such Additional
Shares of Common Stock would be less than the Conversion Price in effect on the
date of and immediately prior to such issue, or such record date, as the case
may be, and provided further that in any such case in which Additional Shares of
Common Stock are deemed to be issued:

                        (1) no further adjustment in the Conversion Price shall
be made upon the subsequent issue of Convertible Securities or shares of Common
Stock upon the exercise of such Options or conversion or exchange of such
Convertible Securities;

                        (2) if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase or
decrease in the consideration payable to the Corporation, or increase or
decrease in the number of shares of Common Stock issuable, upon the exercise,
conversion or exchange thereof, the Conversion Price computed upon the initial
Conversion Prices thereof set forth in Section 4(a) above (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;
<PAGE>

                        (3) on the expiration or cancellation of any Options or
the termination of the right to convert or exchange any Convertible Securities
which shall have not been exercised, if the Conversion Price shall have been
adjusted upon the original issuance thereof or shall have been subsequently
adjusted pursuant to clause (2) above, the Conversion Price shall be recomputed
as if the only Additional Shares of Common Stock issued were shares of Common
Stock, if any, actually issued upon the exercise of such Options or the
conversion or exchange of such Convertible Securities and the consideration
received therefore was the consideration actually received by the Corporation
for the issue of all such Options, whether or not exercised, plus the
consideration actually received by the Corporation upon such exercise, or for
the issue of all such Convertible Securities which were actually converted or
exchanged plus the consideration actually received by the Corporation upon such
conversion or exchange, if any; and

                        (4) no readjustment pursuant to clause (2) or clause (3)
above shall have the effect of increasing the Conversion Price to an amount
which exceeds the lower of (i) the initial Conversion Price on the original
adjustment date (unless the Conversion Price is increased above the initial
Conversion Price pursuant to Section 4(h)(2) or (h)(4)), or (ii) the Conversion
Price that would have resulted from any issuances of Additional Shares of Common
Stock (other than those the subject of such adjustments) between the original
adjustment date and such readjustment date; and

                  (iv) Adjustment of Conversion Price Upon Isuance of Additional
Shares of Common Stock. In the event this Corporation shall issue Additional
Shares of Common Stock (including Additional Shares of Common Stock deemed to be
issued pursuant to Section 4(g)(iii), but excluding stock dividends,
subdivisions or split-ups that are the subject of adjustment pursuant to Section
4(h)) without consideration or for a consideration per share less than the
Conversion Price applicable on and immediately prior to such issue, then and in
such event, the Conversion Price shall be reduced concurrently with such issue,
to a price (calculated to the nearest cent) determined by multiplying the
Conversion Price in effect on the date of and immediately prior to such issue by
a fraction, the numerator of which shall be the sum of (i) the number of shares
of Common Stock outstanding immediately prior to such issue (on a fully diluted
as converted basis), including without limitation the number of shares of Common
Stock issuable upon conversion of the Preferred Stock outstanding immediately
prior to such issue and (ii) the number of shares of Common Stock which the
aggregate consideration received by the Corporation for the total number of
Additional Shares of Common Stock so issued would purchase at the Conversion
Price in effect on the date of and immediately prior to such issue; and the
denominator of which shall be the sum of (i) the number of shares of Common
Stock outstanding immediately prior to such issue (on a fully diluted as
converted basis), including without limitation the number of shares of Common
Stock issuable upon conversion of the Preferred Stock outstanding immediately
prior to such issue and (ii) the number of such Additional Shares of Common
Stock so issued.
<PAGE>

                  (v) Determination of Consideration. For purposes of this
Section 4(g), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                  (1) Cash and Property. Such consideration shall:

                        (A) insofar as it consists of cash, be computed at the
aggregate amount of cash received by the Corporation;

                        (B) insofar as it consists of property other than cash,
be computed at the fair value thereof at the time of such issue, as determined
in good faith by the Board of Directors; and

                        (C) in the event Additional Shares of Common Stock are
issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                  (2) Options and Convertible Securities. The consideration per
share received by the Corporation for Additional Shares of Common Stock deemed
to have been issued pursuant to Section 4(g)(ii) and 4(g)(iii), relating to
Options and Convertible Securities, shall be determined by dividing

                        (A) the total amount, if any, received or receivable by
the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the (ii) aggregate amount of additional consideration (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such options for Convertible Securities and the
conversion or exchange of such Convertible Securities by

                        (B) the maximum number of shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.

            (h) Adjustment of Conversion Price of Series A Preferred, Series B
Preferred and Series C Preferred. The Series A Conversion Price, the Series B
Conversion Price and the Series C Conversion Price shall be subject to
adjustment from time to time as follows:

                  (1) Adjustments for Subdivisions of Common Stock. If the
number of shares of Common Stock outstanding at any time after filing this
Restated Certificate of Incorporation with the Secretary of State of the State
of Delaware is increased by a stock dividend payable in shares of Common Stock
or by a subdivision or
<PAGE>

split up of stock, then the Series A Conversion Price, the Series B Conversion
Price and the Series C Conversion Price then in effect shall, concurrently with
the effectiveness of such dividend, subdivision or split up, be proportionately
decreased so that the number of shares of Common Stock issuable on conversion of
each share of Preferred Stock shall be increased in proportion to such increase
of outstanding shares of Common Stock.

                  (2) Adjustments for Combinations of Common Stock. If the
number of shares of Common Stock outstanding at any time after filing this
Restated Certificate of Incorporation with the Secretary of State of the State
of Delaware is decreased by a combination of the outstanding shares of Common
Stock, then the Series A Conversion Price, the Series B Conversion Price and the
Series C Conversion Price then in effect shall, concurrently with the
effectiveness of such combination, be proportionately increased so that the
number of shares of Common Stock issuable upon conversion of each share of such
Preferred Stock shall be decreased in proportion to such decrease in outstanding
shares of Common Stock.

                  (3) Adjustments for Stock Dividends and Other Distributions.
In the event the Corporation at any time or from time to time makes or fixes a
record date for the determination of holders of Common Stock entitled to receive
any distribution (excluding any repurchases of securities by the Corporation not
made on a pro rata basis from all holders of any class of the Corporation's
securities) payable in property or in securities of the Corporation other than
shares of Common Stock, then and in each such event the holders of Preferred
Stock shall receive at the time of such distribution, the amount of property or
the number of securities of the Corporation that they would have received had
their Preferred Stock been converted into Common Stock on the date of such
event.

                  (4) Adjustments for Reclassification, Exchange and
Substitution. Except as provided in Section 2 upon a Liquidity Event, if the
Common Stock issuable upon conversion of the Preferred Stock shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares provided for above), each share of
Preferred Stock shall thereafter be convertible into the number of shares of
stock or other securities or property to which a holder of the number of shares
of Common Stock of the Corporation deliverable upon such Liquidity Event.

            (i) Amendments to Certificate of Incorporation. The Corporation
shall not amend its Certificate of Incorporation without the approval, by vote
or written consent, by the holders of at least a majority of the then
outstanding shares of Preferred Stock, voting together as a separate class, if
such amendment would amend any of the rights, preferences, privileges of or
limitations provided for herein for the benefit of any shares of Preferred
Stock. Without limiting the generality of the preceding sentence, the
Corporation will not amend its Certificate of Incorporation without the approval
by the holders of at least a majority of the then outstanding shares of
Preferred Stock, voting as a separate class, if such amendment would:
<PAGE>

                  (i) change the relative seniority rights of the holders of
Preferred Stock as to the payment of dividends in relation to the holders of any
other capital stock of the Corporation, or create any other class or series of
capital stock entitled to seniority as to the payment of dividends in relation
to the holders of Preferred Stock;

                  (ii) reduce the amount payable to the holders of Preferred
Stock upon the voluntary or involuntary liquidation, dissolution or winding up
of the Corporation, or change the relative seniority of the liquidation
preferences of the holders of Preferred Stock to the rights upon liquidation of
the holders of other capital stock of the Corporation, or change the dividend
rights of the holders of Preferred Stock;

                  (iii) cancel or modify the redemption rights of the holders of
the Preferred Stock provided for in Section 3 herein; or

                  (iv) cancel or modify the rights of the holders of the
Preferred Stock provided for in this Section 4.

            (j) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Series A Conversion Price, Series B Conversion
Price and the Series C Conversion Price pursuant to this Section 4, the
Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and furnish to each holder of
Preferred Stock a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Series A Conversion Price, the Series B Conversion Price and the Series C
Conversion Price, as applicable, at the time in effect, and (iii) the number of
shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of Preferred Stock. Notwithstanding
the foregoing, no adjustment of the Series A Conversion Price, the Series B
Conversion Price and the Series C Conversion Price shall be made if the amount
of any such adjustment would be an amount less than $1.00, but any such amount
shall be carried forward and an adjustment with respect thereof shall be made at
the time of and together with any subsequent adjustment which, together with
such amount and any other amount(s) so carried forward, shall aggregate an
increase or decrease of $1.00 or more.

            (k) Notices of Record Date. In the event that the Corporation shall
propose at any time:

                  (i) to declare any dividend or distribution upon its Common
Stock, whether in cash, property, stock or other securities, whether or not a
regular cash dividend and whether or not out of earnings or earned surplus;
<PAGE>

                  (ii) to offer for subscription pro rata to the holders of any
class or series of its stock any additional shares of stock of any class or
series or other rights;

                  (iii) to effect any reclassification or recapitalization of
its Common Stock outstanding involving a change in the Common Stock; or

                  (iv) to merge or consolidate with or into any other
corporation, or sell, lease or convey all or substantially all its property or
business, or to liquidate, dissolve or wind up;

                  then, in connection with each such event, the Corporation
shall send to the holders of the Preferred Stock:

                        (1) at least twenty (20) days' prior written notice of
the date on which a record shall be taken for such dividend, distribution or
subscription rights (and specifying the date on which the holders of Common
Stock shall be entitled thereto) or for determining rights to vote in respect
of the matters referred to in (iii) and (iv) above; and

                        (2) in the case of the matters referred to in (iii) and
(iv) above, at least twenty (20) days' prior written notice of the date when the
same shall take place (and specifying the date on which the holders of Common
Stock shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event).

      Each such written notice shall be delivered personally or given by first
class mail, postage prepaid, addressed to the holders of Preferred Stock at the
address for each such holder as shown on the books of the Corporation.

                  (v) Reservation of Shares. The Corporation shall reserve at
all times so long as any shares of Preferred Stock remain outstanding, free from
preemptive rights, out of its treasure stock or its authorized but unissued
shares of Common Stock, or both, solely for the purposes of effecting the
conversion of the shares of Preferred Stock, sufficient shares of Common Stock
to provide for the conversion of all outstanding shares of Preferred Stock.

                  (vi) Valid Issuance. All shares of Common Stock which may be
issued upon conversion of the shares of Preferred Stock will upon issuance by
the Corporation be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issuance thereof and
the Corporation shall take no action which will cause a contrary result."

                               CVC HOLDINGS, INC.

                                    Article I

      The name of the Corporation is CVC Holdings, Inc.

                                   Article II

      The address of the Corporation's registered office in the State of
Delaware is 32 Loockerman Square, Suite L-100, in the City of Dover, County of
Kent. The name of its registercd agent at such address is The Prentice-Hall
Corporation System, Inc.

                                   Article III

      The purpose of the corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the
State of Delaware.

                                   Article IV

      (a) The Corporation is authorized to issue two classes of stock,
designated "Common Stock" and "Preferred Stock." The total number of shares
which the Corporation is authorized to issue is 1,602,500. The total number of
shares of Common Stock which the Corporation is authorized to issue is
1,500,000, par value $.01 per share. The total number of shares of Preferred
Stock which the Corporation is authorized to issue is 102,500, par value $.01
per share, of which 2,500 shares shall be designated 8% Non-Cumulative
Convertible Preferred Stock (the "Series A Preferred") and 100,000 shares shall
be designated Series B Non-Cumulative Convertible Preferred Stock (the "Series B
Preferred"). The Series A Preferred and the Series B Preferred shall
collectively be referred to as the "Preferred Stock."

      The Corporation shall from time to time in accordance with the laws of the
State of Delaware increase the authorized amount of its Common Stock if at any
time the number of shares of Common Stock remaining unissued and available for
issuance shall not be sufficient to permit conversion of the Preferred Stock.

      The relative rights, preferences, privileges and restrictions granted to
or imposed upon the Preferred Stock and the Common Stock or the holders thereof
are as follows:

      Section 1. Dividends. The holders of the Series A Preferred and Series B
Preferred shall be entitled to receive, when and as declared by the Board of
Directors, dividends at the rate of $80.00 per share for Series A Preferred and
$11.90 per share for Series B Preferred (in each case as adjusted for any stock
splits, stock dividends, recapitalizations and the like with respect to such
shares) per annum as the Board of Directors may from time to time determine out
of funds legally available therefor. No dividends shall be paid on the Series A
Preferred during any fiscal year of the Corporation until dividends in the total
amount of $11.90 per share on the Series B Preferred shall have been paid or
declared and set apart during that fiscal year. No dividends (other than those
payable solely in the Common Stock of the Corporation) shall be paid on any
Common Stock of the Corporation during any fiscal year of the Corporation until
dividends in the total amount of $80.00 per share of Series A Preferred and
$11.90 per
<PAGE>

share of the Series B Preferred (in each case as adjusted for any stock splits,
stock dividends, recapitalizations and the like with respect to such shares)
shall have been paid or declared and set apart during that fiscal year. The
right to such dividends on shares of Preferred Stock shall not be cumulative,
and no right shall accrue to holders of Preferred Stock by reason of the fact
that dividends on said shares are not declared in any prior year.

      After payment of such dividends to the holders of the Preferred Stock, any
additional dividends declared shall be distributed among all the holders of the
Common Stock.

      Section 2. Liquidation Preference. In the event of any liquidation,
dissolution, or winding up of the Corporation, either voluntary or involuntary,
distributions to the stockholders of the Corporation shall be made in the
following manner:

            (a) The holders of the Series B Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of the Series A Preferred and
the Common Stock by reason of their ownership of such stock, the amount equal to
the sum of (i) $148.78 per share for each share of Series B Preferred then held
by them (as adjusted for stock splits, stock dividends, recapitalizations and
the like with respect to such stock), and (ii) an amount equal to all declared
but unpaid dividends or distributions on the Series B Preferred. If the assets
and funds thus distributed among the holders of the Series B Preferred pursuant
to this Section 2(a) shall be insufficient to permit the payment to such holders
of the full aforesaid preferential amount, then the entire assets and funds of
the Corporation legally available for distribution shall be distributed ratably
among the holders of the Series B Preferred in proportion to the preferential
amount that each such holder is otherwise entitled to receive.

            (b) After payment has been made to the holders of the Series B
Preferred Stock of the full amounts to which they shall be entitled as set forth
in the first sentence of Section 2(a), then the holders of the Series A
Preferred shall be entitled to receive the amount equal to the sum of(i) $1,000
per share for each share of Series A Preferred then held by them (as adjusted
for stock splits, stock dividends, recapitalizations and the like with respect
to such stock), and (ii) an amount equal to declared but unpaid dividends or
distributions on the Series A Preferred. If the assets and funds thus
distributed among the holders of the Series A Preferred pursuant to this Section
2(b) shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amount, then the entire assets and funds of the
Corporation legally available for distribution pursuant to this Section 2(b)
shall be distributed ratably among the holders of the Series A Preferred in
proportion to the preferential amount that each such holder is otherwise
entitled to receive.

            (c) After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled as set forth in
Section 2(a) and in Section 2(b) above, then the entire remaining assets and
funds of the Corporation legally available for distribution, if any, shall be
distributed on a pro rata basis on the outstanding Common Stock.

            (d) For purposes of this Section 2, a merger or consolidation of the
Corporation with or into any other corporation or corporations, or the merger of
any other corporation or corporations into the Corporation (other than any
merger or consolidation in which stockholders of the Corporation immediately
prior to such merger or consolidation beneficially own a majority of the voting
shares of the surviving corporation immediately following such merger or
consolidation), or a sale of all or


                                      -2-
<PAGE>

substantially all of the assets of the Corporation, shall be treated as a
liquidation, dissolution or winding up of the Corporation.

            (e) Any securities to be delivered to the holders of the Preferred
Stock and Common Stock upon a merger, reorganization or sale of substantially
all the assets of the Corporation shall be valued as follows:

                  (1) if traded on a securities exchange or on the NASDAQ Stock
Market, the value shall be deemed to be the average of the closing prices of the
securities on such exchange over the ten business day period ending three (3)
business days prior to the closing of such merger, reorganization or sale;

                  (2) if actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid prices over the ten business day
period ending three (3) business days prior to the closing; and

                  (3) if there is no active public market, the value shall be
the fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of Series B
Preferred voting as a single class, provided that if the Corporation and the
holders of a majority of the outstanding shares of Series B Preferred are unable
to reach agreement, then by independent appraisal by an investment banker hired
and paid by the Corporation, but reasonably acceptable to the holders of a
majority of the outstanding shares of Series B Preferred voting as a single
class.

      Section 3. Redemption of Series B Preferred.

            (a) At the individual option of each holder of shares of Series B
Preferred, the Corporation shall redeem, on March 31, 2002 (the "Redemption
Date"), the number of shares of Series B Preferred held by such holder that is
specified in a request (the "Redemption Request") for redemption delivered to
the Corporation by the holder on or prior to March 1, 2002, by paying in cash
therefor, $148.78 per share of Series B Preferred (as adjusted for stock splits,
stock dividends, recapitalizations and the like with respect to such shares)
plus all declared but unpaid dividends on such shares (the "Redemption Price").

            (b) At least 10 but no more than 20 days prior to the Redemption
Date written notice shall be mailed, first class postage prepaid, to each holder
of the Series B Preferred which has given the Corporation a Redemption Request
at the address set forth in the Redemption Request, notifying such holder of the
place at which payment may be obtained on the Redemption Date for the shares of
Series B Preferred specified in the Redemption Request and calling upon such
holder to surrender to the Corporation, in the manner and at the place
designated, such holder's certificate or certificates representing the shares to
be redeemed (the "Redemption Notice"). On or after the Redemption Date, each
holder of Series B Preferred to be redeemed shall surrender to this Corporation
the certificate or certificates representing such shares, in the manner and at
the place designated in the Redemption Notice, and thereupon the Redemption
Price of such shares shall be payable to the order of the person whose name
appears on such certificate or certificates as the owner thereof and each
surrendered certificate shall be canceled. In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.

            (c) From and after the Redemption Date, unless there shall have been
a default in payment of the Redemption Price, all rights of the holders of
shares of Series B Preferred designated for redemption in the Redemption Request
as holders of Series B Preferred (except the right to receive the Redemption
Price without interest upon surrender of their certificate or certificates)
shall cease with respect to such shares, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever. If the funds of the Corporation legally available for
redemption of shares of Series B Preferred on the Redemption Date are
insufficient to redeem the total number of shares of Series B Preferred to be
redeemed on such date, those funds which are legally available will be used to
redeem the maximum possible number of such shares ratably among the holders of
such shares to be redeemed based upon their holdings of Series B Preferred. The
shares of Series B Preferred not redeemed shall remain outstanding and entitled
to all the rights and preferences provided herein. At any time thereafter when
additional funds of the Corporation are legally available for the redemption of
shares of Series B Preferred such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obliged to redeem on any
Redemption Date, but which it has not redeemed.

      Section 4. Conversion. The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

            (a) Right to Convert. Each share of the Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the Corporation or any transfer agent
for the Preferred Stock, into such number of fully paid and nonassessable shares
of Common Stock, in the case of the Series A Preferred, as is determined by
dividing $1,000 by the then applicable Series A Conversion Price, and in the
case of the Series B Preferred, as is determined by dividing $148.78 by the then
applicable Series B Conversion Price, determined as hereinafter provided, in
effect at the time of conversion. The price at which shares of Common Stock
shall be deliverable upon conversion of the Series A Preferred (the "Series A
Conversion Price") shall initially be $25 per share of Common Stock and the
price at which shares of Common Stock shall be deliverable upon conversion of
the Series B Preferred (the "Series B Conversion Price") shall initially be
$148.78 per share of Common Stock. Such initial Series A Conversion Price and
Series B Conversion Price shall be subject to adjustment as hereinafter
provided.

            (b) Automatic Conversion. Each share of the Preferred Stock shall
automatically be converted into shares of Common Stock at the then effective
Series A Conversion Price or Series B Conversion Price, as applicable,
immediately prior to the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement on Form S-I (or any
successor form) under the Securities Act of 1933, as amended, covering the offer
and sale of Common Stock for the account of the Corporation to the public at a
price per share (determined without regard to underwriter commissions and
expenses) of not less than Five Hundred Dollars $500.00 (as adjusted for stock
splits, stock dividends, recapitalizations and the like) and aggregate gross
proceeds to the Corporation of not less than Ten Million Dollars ($10,000,000),
before deduction of underwriting discounts and commissions and registration
expenses. In the event of such an offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Preferred Stock shall not
be deemed to have converted such Preferred Stock until immediately prior to the
closing of such underwritten public offering.


                                      -4-
<PAGE>

            (c) Mechanics of Conversion. No fractional shares of Common Stock
shall be issued upon conversion of the Preferred Stock. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall (after aggregating all shares into which shares of Preferred
Stock held by each holder could be converted) pay cash equal to such fraction
multiplied by the Series A Conversion Price or Series B Conversion Price, as
applicable, then in effect. Before any holder of Preferred Stock shall be
entitled to convert the same into full shares of Common Stock and to receive
certificates therefor, the holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent, and shall give written notice to the Corporation at such office
that the holder elects to convert all or any number of shares of the Preferred
Stock represented by such certificate or certificates; provided, however, that
in the event of an automatic conversion pursuant to Section 3(b), the
outstanding shares of Preferred Stock shall be converted automatically without
any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered to the Corporation or its
transfer agent, and provided further, that the Corporation shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable
upon such automatic conversion unless the certificates evidencing such shares of
Preferred Stock are either delivered to the Corporation or its transfer agent as
provided above, or the holder notifies the Corporation or its transfer agent
that such certificates have been lost, stolen or destroyed and executes an
agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. The Corporation shall,
as soon as practicable after such delivery, or such agreement and
indemnification in the case of a lost certificate, issue and deliver at the
office of the Corporation or of any transfer agent, as the case may be, to such
holder of Preferred Stock, a certificate or certificates for the number of
shares of Common Stock to which the holder shall be entitled as aforesaid and a
check payable to the holder in the amount of any cash amounts payable as the
result of a conversion into a fractional share of Common Stock. Such conversion
shall not terminate the rights of the holders of the Preferred Stock or Common
Stock issuable upon conversion of the Preferred Stock to receive dividends which
have been declared with respect to the Preferred Stock prior to the date of
conversion. Except as provided in Section 4(b) above, such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Preferred Stock to be converted, or in the
case of automatic conversion immediately prior to the close of business on the
date of closing of the offering, and the person or persons entitled to receive
the shares of Common Stock issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such shares of Common Stock at
the close of business on such date. If the conversion is in connection with a
firm commitment underwritten public offering of securities registered pursuant
to the Securities Act, the conversion may, at the option of any holder tendering
the Preferred Stock for conversion, be conditioned upon the closing with the
underwriter of the sale of securities pursuant to such offering, in which event
the person(s) entitled to receive the Common Stock issuable upon such conversion
of the Preferred Stock shall not be deemed to have converted such Preferred
Stock until immediately prior to the closing of such sale of securities.

            (d) Series B Preferred Conversion Price Adjustments. The Series B
Conversion Price shall be subject to adjustment from time to time as follows:

                  (i) Special Definitions. For purposes of this Section 4(d),
the following definitions shall apply:

                        (1) "Options" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.

                                      -5-
<PAGE>

                        (2) "Series B Original Issue Date" shall mean the date
on which the first share of Series B Preferred was first issued.

                        (3) "Convertible Securities" shall mean any evidences of
indebtedness, shares (other than Common Stock and Preferred Stock) or other
securities convertible into or exchangeable for Common Stock.

                        (4) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 4(d)(iii) below, deemed
to be issued) by the Corporation after the Series B Original Issue Date other
than shares of Common Stock issued or issuable:

                              (A) upon conversion of shares of the Preferred
Stock or the exercise or conversion of any Options outstanding on the Series B
Original Issue Date;

                              (B) to officers, directors, employees and
consultants of the Corporation or any subsidiary thereof, pursuant to a stock
option plan, stock purchase plan or other employee stock incentive plan approved
by the Board of Directors or other stock arrangements which have been approved
by the Board of Directors;

                              (C) pursuant to any event for which adjustment has
already been made pursuant to this Section 4(d);

                              (D) as a dividend or distribution on the Preferred
Stock;

                              (E) as a dividend or distribution on the Common
Stock;

                              (F) upon any subdivision or split up of Common
Stock; or

                              (G) upon any capital reorganization of the
Corporation.

                  (ii) No Adjustment of Conversion Price. No adjustment in the
Series B Conversion Price shall be made in respect of the issuance of Additional
Shares of Common Stock unless the consideration per share for an Additional
Share of Common Stock issued or deemed to be issued by the Corporation is less
than the Series B Conversion Price, in effect on the date of and immediately
prior to such issue.

                  (iii) Deemed Issue of Additional Shares of Common Stock.
Except as provided in Section 4(d)(i)(4) above, in the event the Corporation at
any time or from time to time after the Series B Original Issue Date shall issue
any Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such a record date shall have been fixed, as
of the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined

                                      -6-
<PAGE>

pursuant to Section 4(d)(v) below) of such Additional Shares of Common Stock
would be less than the Series B Conversion Price in effect on the date of and
immediately prior to such issue, or such record date, as the case may be, and
provided further that in any such case in which Additional Shares of Common are
deemed to be issued:

                        (1) no further adjustment in the Series B Conversion
Price shall be made upon the subsequent issue of Convertible Securities or
shares of Common Stock upon the exercise of such Options or conversion or
exchange of such Convertible Securities;

                        (2) if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase or
decrease in the consideration payable to the Corporation, or increase or
decrease in the number of shares of Common Stock issuable, upon the exercise,
conversion or exchange thereof, the Series B Conversion Price computed upon the
initial conversion prices thereof set forth in Section 4(a) above (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                        (3) on the expiration or cancellation of any Options or
the termination of the right to convert or exchange any Convertible Securities
which shall have not been exercised, if the Series B Conversion Price shall have
been adjusted upon the original issuance thereof or shall have been subsequently
adjusted pursuant to clause (2) above, the Series B Conversion Price shall be
recomputed as if the only Additional Shares of Common Stock issued were shares
of Common Stock, if any, actually issued upon the exercise of such Options or
the conversion or exchange of such Convertible Securities and the consideration
received therefore was the consideration actually received by the Corporation
for the issue of all such Options, whether or not exercised, plus the
consideration actually received by the Corporation upon such exercise, or for
the issue of all such Convertible Securities which were actually converted or
exchanged plus the consideration actually received by the Corporation upon such
conversion or exchange, if any; and

                        (4) no readjustment pursuant to clause (2) or clause (3)
above shall have the effect of increasing the Series B Conversion Price to an
amount which exceeds the lower of (i) the initial Series B Conversion Price on
the original adjustment date (unless the Series B Conversion Price is increased
above the initial Series B Conversion Price pursuant to Section 4(e)(2) or
(e)(4)), or (ii) the Series B Conversion Price that would have resulted from any
issuances of Additional Shares of Common Stock (other than those the subject of
such adjustments) between the original adjustment date and such readjustment
date; and

                  (iv) Adjustment of Series B Conversion Price Upon Issuance of
Additional Shares of Common Stock. In the event this Corporation shall issue
Additional Shares of Common Stock (including Additional Shares of Common Stock
deemed to be issued pursuant to Section 4(d)(iii), but excluding stock
dividends, subdivisions or split-ups that are the subject of adjustment pursuant
to Section 4(e)) without consideration or for a consideration per share less
than the Series B Conversion Price applicable on and immediately prior to such
issue, then and in such event, the Series B Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying the Series B Conversion Price in effect on the date of
and immediately prior to such issue by a fraction, the numerator of which shall
be the sum of (i) the number of shares of Common Stock


                                      -7-
<PAGE>

outstanding immediately prior to such issue (on a fully diluted as converted
basis), including without limitation the number of shares of Common Stock
issuable upon conversion of the Preferred Stock outstanding immediately prior to
such issue and (ii) the number of shares of Common Stock which the aggregate
consideration received by the Corporation for the total number of Additional
Shares of Common Stocks so issued would purchase at the Series B Conversion
Price in effect on the date of and immediately prior to such issue; and the
denominator of which shall be the sum of (i) the number of shares of Common
Stock outstanding immediately prior to such issue (on a fully diluted as
converted basis), including without limitation the number of shares of Common
Stock issuable upon conversion of the Preferred Stock outstanding immediately
prior to such issue and (ii) the number of such Additional Shares of Common
Stock so issued.

            (v) Determination of Consideration. For purposes of this Section
4(d), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                  (1) Cash and Property. Such consideration shall:

                        (A) insofar as it consists of cash, be computed at the
aggregate amount of cash received by the Corporation;

                        (B) insofar as it consists of property other than cash,
be computed at the fair value thereof at the time of such issue, as determined
in good faith by the Board of Directors; and

                        (C) in the event Additional Shares of Common Stock are
issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                  (2) Options and Convertible Securities. The consideration per
share received by the Corporation for Additional Shares of Common Stock deemed
to have been issued pursuant to Section 4(d)(ii) and 4(d)(iii), relating to
Options and Convertible Securities, shall be determined by dividing

                        (A) the total amount, if any, received or receivable by
the Corporation as consideration for the issue of such Options or Convertible
Securities, plus the minimum aggregate amount of additional consideration (as
set forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such consideration) payable to
the Corporation upon the exercise of such Options or the conversion or exchange
of such Convertible Securities, or in the case of Options for Convertible
Securities, the exercise of such options for Convertible Securities and the
conversion or exchange of such Convertible Securities by

                        (B) the maximum number of shares of Common Stock (as set
forth in the instruments relating thereto, without regard to any provision
contained therein for a subsequent adjustment of such number) issuable upon the
exercise of such Options or the conversion or exchange of such Convertible
Securities.


                                      -8-
<PAGE>

            (e) Adjustment of Conversion Price of Both Series A Preferred and
Series B Preferred. The Series A Conversion Price and the Series B Conversion
Price shall be subject to adjustment from time to time as follows:

                  (1) Adjustments for Subdivisions of Common Stock. If the
number of shares of Common Stock outstanding at any time after filing this
Restated Certificate of incorporation with the Secretary of State of the State
of Delaware is increased by a stock dividend payable in shares of Common Stock
or by a subdivision or split up of stock, then the Series A Conversion Price and
the Series B Conversion Price then in effect shall, concurrently with the
effectiveness of such dividend, subdivision or split up, be proportionately
decreased so that the number of shares of Common Stock issuable on conversion of
each share of Preferred Stock shall be increased in proportion to such increase
of outstanding shares of Common Stock.

                  (2) Adjustments for Combinations of Common Stock. If the
number of shares of Common stock outstanding at any time after filing this
Restated Certificate of incorporation with the Secretary of State of the State
of Delaware is decreased by a combination of the outstanding shares of Common
Stock, then the Series A Conversion Price and the Series B Conversion Price then
in effect shall, concurrently with the effectiveness of such combination, be
proportionately increased so that the number of shares of Common Stock issuable
upon conversion of each share of such Preferred Stock shall be decreased in
proportion to such decrease in outstanding shares of Common Stock.

                  (3) Adjustments for Stock Dividends and Other Distributions.
In the event the Corporation at any time or from time so time makes, or fixes a
record date for the determination of holders of Common Stock entitled to receive
any distribution (excluding any repurchases of securities by the Corporation not
made on a pro rata basis from all holders of any class of the Corporation's
securities) payable in property or in securities of the Corporation other than
shares of Common Stock, then and in each such event the holders of Preferred
Stock shall receive at the time of such distribution, the amount of property or
the number of securities of the Corporation that they would have received had
their Preferred Stock been converted into Common Stock on the date of such
event.

                  (4) Adjustments for Reclassification, Exchange and
Substitution. Except as provided in Section 2 upon any liquidation, dissolution
or winding up of the Corporation, if the Common Stock issuable upon conversion
of the Preferred Stock shall be changed into the same or a different number of
shares of any other class or classes of stock, whether by capital
reorganization, reclassification or otherwise (other than a subdivision or
combination of shares provided for above), each share of Preferred Stock shall
thereafter be convertible into the number of shares of stock or other securities
or property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such share of Preferred Stock shall
have been entitled upon such reorganization or reclassification.

            (f) No Impairment. The Corporation will not, by amendment of its
Certificate of Incorporation or By-laws or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed hereunder by the Corporation but
will at all times in good faith assist in the carrying out of all the provisions
of this Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the holders of the
Preferred Stock against impairment


                                      -9-
<PAGE>

            (g) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Series A Conversion Price or Series B
Conversion Price pursuant to this Section 4, the Corporation at its expense
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and furnish to each bolder of Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. The Corporation shall, upon the
written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Series A Conversion Price or the Series
B Conversion Price, as applicable, at the time in effect, and (iii) the number
of shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of Preferred Stock. Notwithstanding
the foregoing, no adjustment of the Series A Conversion Price or the Series B
Conversion Price shall be made if the amount of any such adjustment would be an
amount less than $1.00, but any such amount shall be carried forward and an
adjustment with respect thereof shall be made at the time of and together with
any subsequent adjustment which, together with such amount and any other
amount(s) so carried forward, shall aggregate an increase or decrease of $1.00
or more.

            (h) Notices of Record Date. In the event that the Corporation shall
propose at any time:

                  (i) to declare any dividend or distribution upon its Common
Stock, whether in cash, property, stock or other securities, whether or not a
regular cash dividend and whether or not out of earnings or earned surplus;

                  (ii) to offer for subscription pro rata to the holders of any
class or series of its stock any additional shares of stock of any class or
series or other rights;

                  (iii) to effect any reclassification or recapitalization of
its Common Stock outstanding involving a change in the Common Stock; or

                  (iv) to merge or consolidate with or into any other
corporation, or sell, lease or convey all or substantially all its property or
business, or to liquidate, dissolve or wind up;

                        then, in connection with each such event, the
Corporation shall send to the holders of the Preferred Stock:

                        (1) at least 20 days' prior written notice of the date
on which a record shall be taken for such dividend, distribution or subscription
rights (and specifying the date on which the holders of Common Stock shall be
entitled thereto) or for determining rights to vote in respect of the matters
referred to in (iii) and (iv) above; and

                        (2) in the case of the matters referred to in (iii) and
(iv) above, at least 20 days' prior written notice of the date when the same
shall take place (and specifying the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event).

                                      -10-
<PAGE>

      Each such written notice shall be delivered personally or given by first
class mail, postage prepaid, addressed to the holders of Preferred Stock at the
address for each such holder as shown on the books of the Corporation.

                  (v) Reservation of Shares. The Corporation shall reserve at
all times so long as any shares of Preferred Stock remain outstanding, free from
preemptive rights, out of its treasure stock or its authorized but unissued
shares of Common Stock, or both, solely for the purposes of effecting the
conversion of the shares of Preferred Stock, sufficient shares of Common Stock
to provide for the conversion of all outstanding shares of Preferred Stock.

                  (vi) Valid Issuance. All shares of Common Stock which may be
issued upon conversion of the shares of Preferred Stock will upon issuance by
the Corporation be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issuance thereof and
the Corporation shall take no action which will cause a contrary result.

      Section 5. Voting Rights and Directors.

            (a) Except as otherwise provided herein or required by law, the
holder of each share of Common Stock issued and outstanding shall have one vote
with respect to such share and the holder of each share of Preferred Stock shall
be entitled with respect to such share to a number of votes equal to the number
of shares of Common Stock into which such share of Preferred Stock could be
converted at the record date for determination of the stockholders entitled to
vote on such matters, or, if no such record date is established, at the date
such vote is taken or any written consent of stockholders is solicited, such
votes to be counted together with all other shares of stock of the Company
having general voting power and not separately as a class (except as required by
Section 5(b) below, Section 6 or by the General Corporation Law of Delaware).
Holders of Common Stock and Preferred Stock shall be entitled to notice of any
stockholders' meeting in accordance with the Bylaws of the Corporation.
Fractional votes by the holders of Preferred Stock shall not, however, be
permitted and any fractional voting rights shall (after aggregating all shares
into which shares of Preferred Stock held by each holder could be convened) be
rounded to the nearest whole number.

            (b) The Board of Directors shall consist of seven (7) members. The
holders of the Series B Preferred, voting separately as a class, shall be
entitled to elect two (2) members of the Board of Directors. The holders of
Common Stock and Series A Preferred, voting together, shall be entitled to elect
the remaining members of the Board of Directors. At any meeting held for the
purpose of electing or removing directors, (i) the presence in person or by
proxy of the holders of the majority of the shares of Series B Preferred then
outstanding shall constitute a quorum of the Series B Preferred for the purpose
of electing or removing directors by holders of the Series B Preferred and (ii)
the presence in person or by proxy of the holders of a majority of shares of
Common Stock and Series A Preferred (on an as converted into Common Stock basis)
then outstanding shall constitute a quorum of Common Stock and Series A
Preferred for the purpose of electing or removing directors by holders of Common
Stock and Series A Preferred. A vacancy in any directorship elected by the
holders of the Series B Preferred shall be filled only by vote or written
consent in lieu of a meeting of the holders of the Series B Preferred. A vacancy
in any directorship elected by the holders of Common Stock and Series A
Preferred shall be filled only by vote or written consent in lieu of a meeting
of the holders or Common Stock and the Series A Preferred. Any member of the
Board of Directors elected by the holders of the Series B


                                      -11-
<PAGE>

Preferred may only be removed by the vote of the holders of not less than a
majority of the shares of Series B Preferred voting thereon. Any member of the
Board of Directors elected by the holders of Common Stock and Series A Preferred
may only be removed by the vote of the holders of not less than a majority of
the shares of Common Stock and Series A Preferred (on an as converted into
Common Stock basis) voting thereon.

            (c) At all elections of members of the Board of Directors of the
Corporation, if any holder of stock of this Corporation entitled to vote at an
election shall have given the Corporation written notice of its intention to
cumulate his or her votes for the election of members of the Board of Directors
prior to the commencement of the voting for such members, then each holder
entitled to vote for members of the Board of Directors shall be entitled to as
many votes as shall equal the number of votes which (except for this provision
as to cumulative voting) such holder would be entitled to cast for the election
of directors with respect to his or her shares of stock multiplied by the number
of directors to be elected by such holder either (i) by casting all such
holder's votes for a single director or (ii) by distributing such holder's votes
among the number of directors to be voted for, or for any two or more of them as
such holder may see fit.

      Section 6. Covenants. In addition to any other rights provided by law, so
long as any Series B Preferred shall be outstanding, the Corporation shall not,
without first obtaining the written consent of the holders of not less than a
majority of the then outstanding shares of Series B Preferred:

            (a) amend or repeal any provision of, or add any provision to, this
Corporation's Restated Certificate of Incorporation if such action would change
adversely the preferences, rights, privileges or powers of, or the restrictions

                                RESTATED BY-LAWS

                                       OF

                               CVC HOLDINGS, INC.

                            (A Delaware Corporation)

                                   ARTICLE I

                             STOCK AND STOCKHOLDERS

            1. CERTIFICATES REPRESENTING STOCK. Every holder of stock in the
corporation shall be entitled to have a certificate signed by, or in the name
of, the corporation by the President or a Vice-President and by the Treasurer or
an Assistant Treasurer or the Secretary or an Assistant Secretary of the
corporation certifying the number of shares owned by him in the corporation. Any
and all signatures on any such certificate may be facsimiles. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue.

            Whenever the corporation shall be authorized to issue more than one
class of stock or more than one series of any class of stock, and whenever the
corporation shall issue any shares of its stock as partly paid stock, the
certificate representing shares of any such class or series or of any such
partly paid stock shall set forth thereon the statements prescribed by the
General Corporation Law. Any restrictions on the transfer or registration of
transfer of any shares of stock of any class or series shall be noted
conspicuously on the certificate representing such shares.

            The corporation may issue a new certificate of stock in place of any
certificate theretofore issued by it, alleged to have been lost, stolen, or
destroyed, and the Board of Directors may require the owner of any lost, stolen,
or destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify the corporation against any claim that may be made
against it on account of the alleged loss, theft, or destruction of any such
certificate or the issuance of any such new certificate.

            2. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be
required to, issue fractions of a share of stock. If the corporation does not
issue fractions of a share, it shall (1) arrange for the disposition of
fractional interests by those entitled thereto, (2) pay in cash the fair value
of fractions of a share of stock as of the time when those entitled to receive
such fractions are determined, (3) issue scrip or warrants in registered or
bearer form which shall entitle the holder to receive a certificate

<PAGE>

for a full share upon the surrender of such scrip or warrants aggregating a full
share. A certificate for a fractional share shall, but such scrip or warrants
shall not unless provided therein, entitle the holder to exercise voting rights,
to receive dividends thereon, and to participate in any of the assets of the
corporation in the event of liquidation. The Board of Director's may cause scrip
or warrants to be issued subject to the condition that they shall become void if
not exchanged for certificates representing full shares of stock before a
specified date, or subject to the condition that the shares of stock for which
scrip or warrants are exchangeable may be sold by the corporation and the
proceeds thereof distributed to the holders of scrip or warrants, or subject to
any other conditions which the Board of Directors may determine.

            3. STOCK TRANSFERS. Upon compliance with provisions restricting the
transfer or registration of transfer of shares of stock, if any, transfers or
registration of transfers of shares of stock of the corporation shall be made
only on the stock ledger of the corporation by the registered holder thereof, or
by his attorney thereunder authorized by power of attorney duly executed and
filed with the Secretary of the corporation or with a transfer agent or a
registrar, if any, and on surrender of the certificate or certificates for such
shares of stock properly endorsed and the payment of all taxes due thereon.

            4. RECORD DATE FOR STOCKHOLDERS. For the purpose of determining the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to or dissent from any corporate
action in writing without a meeting, or entitled to receive payment of any
dividend or other distribution or the allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion, or exchange of stock,
or for the purpose of any other lawful action, the directors may fix, in
advance, a date as the record date for any such determination of stockholders.
Such date shall not be more than sixty days nor less than ten days before the
date of such meeting, nor more than sixty days prior to any other action. If no
record date is fixed, the record date for the determination of stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day next preceding the day on which notice is given,
or, if notice is waived, at the close of business on the day next preceding the
day on which the meeting is held; the record date for determining stockholders
entitled to express consent to corporate action in writing without a meeting,
when no prior action by the Board of Directors is necessary, shall be the day on
which the first written consent is expressed; and the record date for
determining stockholders for any other purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto. When a determination of stockholders of record entitled to notice of or
to vote at any meeting of stockholders has been made as provided in this
paragraph, such determination shall apply to any adjournment thereof; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

            5. STOCKHOLDER MEETINGS.

            - TIME. The annual meeting shall be held on the date and at the time
fixed from time to time by the Board of Directors, provided, that the first
annual meeting shall be held on a date within thirteen months after the
organization of the corporation,


                                       2
<PAGE>

and each successive annual meeting shall be held on date within thirteen months
after the date of the preceding annual meeting. A special meeting shall be held
on the date and at the time fixed by the Board of Directors.

            - PLACE. Annual meetings and special meetings shall be held at such
place, within or without the State of Delaware, as the Board of Directors may
from time to time fix. Whenever the Board of Directors shall fail to fix such
place, the meeting shall be held at the principal executive office of the
corporation.

            - CALL. Annual meetings and special meetings may be called by the
Board of Directors, the President, or any two or more directors, and shall be
called by the President or a Vice President or the Secretary at the written
demand of the holders of at least one-fourth of all outstanding shares entitled
to vote on the action proposed to be taken at such meeting, which demand shall
state the purpose or purposes of the proposed meeting.

            - NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall
be given, stating the place, date, and hour of the meeting and stating the place
within the city or other municipality or community at which the list of
stockholders of the corporation may be examined. The notice of an annual meeting
shall state that the meeting is called for the election of directors and for the
transaction of other business which may properly come before the meeting, and
shall (if any other action which could be taken at a special meeting is to be
taken at such annual meeting) state the purpose or purposes. The notice of a
special meeting shall in all instances state the purpose or purposes for which
the meeting is called. The notice of any meeting shall also include, or be
accompanied by, any additional statements, information or documents prescribed
by the General Corporation Law. Except as otherwise provided by the General
Corporation Law, a copy of the notice of any meeting shall be given, personally
or by mail, not less than ten days nor more than sixty days before the date of
the meeting, unless the lapse of the prescribed period of time shall have been
waived, and directed to each stockholder at his record address or at such other
address which he may have furnished by request in writing to the Secretary of
the corporation. Notice by mail shall be deemed to be given when deposited, with
postage thereon prepaid, in the United States mail. If a meeting is adjourned to
another time, not more than thirty days hence, and/or to another place, and if
an announcement of the adjourned time and place is made at the meeting, it shall
not be necessary to give notice of the adjourned meeting unless the directors,
after adjournment, fix a new record date for the adjourned meeting. Notice need
not be given to any stockholder who submits a written waiver of notice signed by
him before or after the time stated therein. Attendance of a person at a meeting
of stockholders shall constitute a waiver of notice of such meeting, except when
the Stockholder attends a meeting for the express purpose of objecting, at the
beginning of the meeting, to the transaction of any business because the meeting
is not lawfully called or convened. Neither the business to be transacted at,
nor the purpose of, any regular or special meeting of the stockholders need be
specified in any written waiver of notice.

            - STOCKHOLDER LIST. The officer who was charge of the stock ledger
of the corporation shall prepare and make, at least ten days before every
meeting


                                       3
<PAGE>

of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city or other
municipality or community where the meeting is to be held, which place shall be
specified in the notice of the meeting, or if not so specified, at the place
where the meeting is to be held. The list shall also be produced and kept at the
time and place of the meeting during the whole time thereof, and may be
inspected by any stockholder who is present. The stock ledger shall be the only
evidence as to who are the stockholders entitled to examine the stock ledger,
the list required by this section or the books of the corporation, or to vote in
person or by proxy at any meeting of stockholders.

            - CONDUCT OF MEETING. Meetings of the stockholders shall be presided
over by one of the following officers in the order of seniority and if present
and acting - the President, a Vice-President, or, if none of the foregoing is in
office and present and acting, by a chairman to be chosen by the stockholders.
The Secretary of the corporation, or in his absence, an Assistant Secretary,
shall act as secretary of every meeting, but if neither the Secretary nor an
Assistant Secretary is present the chairman of the meeting shall appoint a
secretary of the meeting.

            - PROXY REPRESENTATION. Each stockholder entitled to vote at a
meeting of stockholders, or to express consent or dissent to corporate action
without a meeting, may authorize another person or persons to act for him by
proxy. Every proxy must be signed by the stockholder or by his attorney-in-fact.
No Proxy shall be voted or acted upon after three years from its date unless
such proxy provides for a longer period. A duly executed proxy shall be
irrevocable if it states that it is irrevocable and, if, and only as long as, it
is coupled with an interest sufficient in law to support an irrevocable power. A
Proxy may be made irrevocable regardless of whether the interest with which it
is coupled is an interest in the stock itself or an interest in the corporation
generally.

            - INSPECTORS AND JUDGES. The Board of Directors, in advance of any
meeting, may, but need not, appoint one or more inspectors of election or judges
of the vote, as the case may be, to act at the meeting or any adjournment
thereof. If an inspector or inspectors or judge or judges are not appointed, the
person presiding at the meeting may, but need not, appoint one or more
inspectors or judges. In case any person who may be appointed as an inspector or
judge fails to appear or act, the vacancy may be filled by appointment made by
the directors in advance of the meeting or at the meeting by the person
presiding thereat. Each inspector or judge, if any, before entering upon the
discharge of his duties, shall take and sign an oath faithfully to execute the
duties of inspector or judge at such meeting with strict impartiality and
according to the best of his ability. The inspectors or judges, if any, shall
determine the number of shares of stock outstanding and the voting power of
each, the shares of stock represented at the meeting, the existence of a quorum
and the validity and effect of proxies, and shall receive votes, ballots or
consents, hear and shall receive votes, ballots or consent, hear and determine
all challenges and questions arising in connection with the right to vote, count
and tabulate all votes, ballots or consents, determine the result, and do such
acts as are proper to


                                       4
<PAGE>

conduct the election or vote with fairness to all stockholders. On request of
the person presiding at the meeting, the inspector or inspectors or judge or
judges, if any, shall make a report in writing of any challenge, question or
matter determined by him or them and execute a certificate of any fact found by
him or them.

            - QUORUM. The holders of a majority of the outstanding shares of
stock entitled to vote, present in person or represented by proxy, shall
constitute a quorum at a meeting of stockholders for the transaction of any
business. The stockholders present may adjourn the meeting despite the absence
of a quorum.

            - VOTING. Except as otherwise provided by the General Corporation
Law or by the Certificate of Incorporation, each share of stock entitled to vote
shall entitle the holder thereof to one vote. In the election of directors, a
plurality of the votes cast shall elect. Directors shall be elected by
cumulative voting, if and as provided in the Certificate of Incorporation. Any
other action shall be authorized by a majority of the votes cast except where
the General Corporation Law or these by-laws or the Certificate of Incorporation
prescribes a different percentage of votes and/or a different exercise of voting
power. In the election of directors, voting need not be by ballot. Voting by
ballot shall not be required for any other corporate action except as otherwise
provided by the General Corporation Law.

            6. STOCKHOLDER ACTION WITHOUT A MEETING. Any action required by the
General Corporation Law to be taken or which may be taken at any annual or
special meeting of stockholders may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted. Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those stockholders who
have not consented in writing.

                                   ARTICLE II

                                    DIRECTORS

            1. FUNCTIONS AND DEFINITION. The business of the corporation shall
be managed by or under the direction of the Board of Directors of the
corporation. The use of the phrase "whole Board" herein refers to the total
number of directors which the corporation would have if there were no vacancies.

            2. QUALIFICATIONS AND NUMBER. A director need not be a stockholder,
a citizen of the United States, or a resident of the State of Delaware. The
number of directors shall be no less than three, nor more than ten, such number
to be fixed from time to time solely by resolution of the Board of Directors.
The number of directors may be increased or decreased by action of the
stockholders or of the Board.

            3. ELECTION AND TERM. The first Board of Directors, unless the


                                       5
<PAGE>

members thereof shall have been named in the Certificate of Incorporation, shall
be elected by the incorporator or incorporators and shall hold office until the
first annual meeting of stockholders and until their successors have been
elected and qualified or until their earlier resignation or removal. Thereafter,
directors who are elected at an annual meeting of stockholders, and directors
who are elected in the interim to fill vacancies and newly created
directorships, shall hold office until the next annual meeting of stockholders
and until their successors have been elected and qualified or until their
earlier resignation or removal. In the interim between annual meetings of
stockholders or of special meetings of stockholders called for the election of
directors and/or for the removal of one or more of the directors and for the
filling of any vacancy in that connection, newly created directorships and any
vacancies in the Board of Directors, including vacancies resulting from the
removal of directors for cause or without cause, may be filled only by the vote
or written consents in lieu of meeting of the class of stockholders entitled to
elect such director. At any meeting held for the purpose of electing a director
or directors, the presence in person or by proxy of the holders of the majority
of shares then outstanding of the class entitled to vote for the election of
such director or directors shall constitute a quorum for the purpose of electing
a director or directors by the stockholders of such class.

            4. MEETINGS.

            - TIME. Meetings shall be held at such time as the Board shall fix,
except that the first meeting of a newly elected Board shall be held as soon
after its election as the directors may conveniently assemble.

            - PLACE. Meeting shall be held at such place within or without the
State of Delaware as shall be fixed by the Board.

            - CALL. No call shall be required for regular meetings for which the
time and place have been fixed. Special meetings may be called by or at the
direction of the President, or any two (2) of the directors in office.

            - NOTICE OR ACTUAL OR CONSTRUCTIVE WAIVER. No notice shall be
required for regular meetings for which the time and place have been fixed.
Written, oral, or any other mode of notice of the time and place shall be given
for special meetings in sufficient time for the convenient assembly of the
directors thereat. The notice of any regular or special meeting shall specify
the business to be transacted at the meeting and/or the purpose or purposes for
which such meeting is being called, and no other business or purpose may be
conducted or considered at such meeting. Notice need not be given to any
director who submits a written waiver of notice signed by him before or after
the time of the meeting. Attendance of any such person at a meeting shall
constitute a waiver of notice of such meeting, except when he attends a meeting
for the sole purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting need be specified in any written waiver of notice.


                                       6
<PAGE>

            - QUORUM AND ACTION. A majority of the whole Board shall constitute
a quorum except when a vacancy or vacancies prevents such majority, whereupon a
majority of the directors in office shall constitute a quorum, provided, that
such majority shall constitute at least one-third of the whole Board, except
that if the number of directors constituting the whole Board is one, then one
director shall constitute a quorum. A majority of the directors present, whether
or not a quorum is present, may adjourn a meeting to another time and place.
Except as herein otherwise provided, and except as otherwise provided by the
General Corporation law and the Certificate of Incorporation, the act of the
Board shall be the act by vote of a majority of the directors present at a
meeting at which a quorum is present.

            - CHAIRMAN OF THE MEETING. The President shall preside at all
meetings. If, for any reason, the President is not present at any meeting, any
director chosen by the Board shall preside.

            5. REMOVAL OF DIRECTORS. Except as may otherwise be provided by the
General Corporation Law or the Certificate of Incorporation, any or all of the
directors elected by a class of stockholders may only be removed by the vote of
the holders of not less than a majority of the shared of such class voting
thereon, provided, however, that in case of the corporation having cumulative
voting, no director may be removed without cause if the votes against his
removal would be sufficient to elect him if voted cumulatively at an election of
directors at which the same number of votes were case and the whole Board were
then being elected. At any meeting held for the purpose of removing a director
or directors, the presence in person or by proxy of the holders of the majority
of shares then outstanding of the class entitled to vote for the removal of such
director or directors shall constitute a quorum for the purpose of removing a
director or directors by the stockholders of such class.

            6. COMMITTEES. The Board may, by resolution passed by a majority of
the whole Board, designate one or more committees, each committee to consist of
one or more of the directors of the corporation. The Board may designate one or
more directors as alternate members of any committee who may replace any absent
or disqualified member at any meeting of the committee. Any such committee, to
the extent provided in the resolution of the Board and except as hereinafter
provided, shall have and may exercise the powers of the Board of Directors in
the management of the business and affairs of the corporation, and may authorize
the seal of the corporation to be affixed to all papers which may require it. No
such committee shall the power or authority to amend the Certificate of
Incorporation, adopt an agreement of merger or consolidation, recommend to the
stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, recommend to the stockholders a dissolution
of the corporation or a revocation of a dissolution, declare a dividend,
authorize the issuance of stock, elect or remove any officer, amend or repeal
any resolution adopted by the Board or take any action prohibited by the General
Corporation Law. The notice provisions of these By-Laws pertaining to directors'
meetings shall also apply to all committee meetings.

<PAGE>

            7. ACTION IN WRITING. Any action required or permitted to be taken
at any meeting of the Board of Directors or any committee thereof may be taken
without a meeting if all members of the Board or committee, as the case may be,

                                 INDEMNIFICATION

            1. LIMITATION OF CERTAIN LIABILITY OF DIRECTORS. To the fullest
extent permitted by the Delaware General Corporation Law as the same exists or
may hereafter be amended, a director of the corporation shall not be liable to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as director.

            2. INDEMNIFICATION AND INSURANCE. (a) Each person who was or is made
a party or is threatened to be made a party to or is involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a


                                       9
<PAGE>

"proceeding") by reason of the fact that he or she, or a person of whom he or
she is the legal representative, is or was a director or officer of the
corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged action
in an official capacity as a director, officer, employee or agent or in any
other capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by the corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the corporation to provide broader indemnification
rights than said law permitted the corporation to provide prior to such
amendment) against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid
in settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators; provided, however, that, except
as provided in paragraph (b) hereof, the corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such Proceeding (or part thereof) was
authorized by the Board of Directors of the corporation. The right to
indemnification conferred in this Section 2 shall be a contract right and shall
include the right to be paid by the corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that if the Delaware General Corporation Law requires, the payment of
such expenses incurred by a director or officer in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer, including without
limitation service to an employee benefit plan) in advance of the final
disposition of a proceeding shall be made only upon delivery to the corporation
of an undertaking, by or on behalf of such director or officer, to repay all
amounts so advanced if it shall ultimately be determined that such director or
officer is not entitled to be indemnified under this Section 2 or otherwise. The
corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of the corporation with the same scope and effect as the
foregoing indemnification of directors and officers.

            (b) If a claim under paragraph (a) of this Section 2 is not paid in
full by the corporation within ninety days after a written claim has been
received by the corporation, the claimant may at any time thereafter bring suit
against the corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim. It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the corporation) that the
claimant has not met the standards of conduct which make it permissible under
the Delaware General Corporation Law for the corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall be
on the corporation. Neither the failure of the corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that


                                       10
<PAGE>

indemnification of the claimant is proper in the circumstances because he or she
has met the applicable standard of conduct set forth in the Delaware General
Corporation Law, nor an actual determination by the corporation (including its
Board of Directors independent legal counsel, or its stockholders) that the
claimant has not met such applicable standard of conduct, shall be a defense to
the action or create a presumption that the claimant has not met the applicable
standard of conduct.

            3. EXCLUSIVITY OF RIGHTS. The right to indemnification and the
payment of expenses conferred in this Article shall not be deemed exclusive of
any other right to which any person seeking indemnification or payment of
expenses may be entitled under any statute, provision the Certificate of
Incorporation, by-law, agreement, vote of stockholders or disinterested
directors or otherwise, both as to action in such person's official capacity and
as to action in another capacity while holding such office, and shall continue
as to a person who has ceased to be a director, officer, employee or agent and
shall inure to the benefit of the heirs, executors and administrators of such a
person.

            4. INSURANCE. The corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

                                   ARTICLE V

                  CONTRACTS, LOANS, CHECKS, NOTES, DRAFTS, ETC.

            Contracts, checks, notes, drafts, acceptances, bills of exchange and
other instruments, orders or obligations for the payment of money shall be
signed by the President or by such officer or officers or person or persons as
the Board or the President shall from time to time determine.

                                   ARTICLE VI

                                 CORPORATE SEAL

            The corporate seal shall be in such form as the Board shall
prescribe.

                                  ARTICLE VII

                                   FISCAL YEAR

            The fiscal year of the corporation shall be fixed, and shall be
subject to change, by the Board.

            The Board of Directors shall have the power to make, alter or repeal
the By-Laws of the corporation subject to the power of the stockholders to alter
or repeal the By-Laws made or altered by the Board of Directors. The
stockholders shall also have the power to make, alter or repeal the By-Laws of
the corporation.

Option.

                                   ARTICLE IV

                                 ADMINISTRATION

            4.1 Committee Members. The Plan shall be administered by a Committee
comprised of no fewer than two persons selected by the Board. Solely to the
extent deemed necessary or advisable by the Board, each Committee member shall
meet the definition of a "nonemployee director" for purposes of such Rule 16b-3
under the Exchange Act and of an "outside director" under Section 162(m) of the
Code. The Board shall also have the authority to exercise the powers and duties

Plan, the Committee shall have the authority, in its discretion, to determine
the Eligible Persons to whom an Option shall be granted, the time or times at
which an Option shall be granted, the number of shares of Common Stock subject

                                    ARTICLE V

                         SHARES OF STOCK SUBJECT TO PLAN

            5.1 Number of Shares. Subject to adjustment pursuant to the
provisions of Section 5.2 hereof, the number of shares of Common Stock which may
be issued and sold hereunder shall initially be 2,750,000 shares, provided that,
effective as of each fiscal year beginning on October 1, 2000, a number of
shares shall be added to the number of shares available for issuance under the
Plan that is equal to 5% of the total number of shares of Common Stock issued by
the Company during the immediately preceding fiscal year. Notwithstanding the
foregoing, the maximum aggregate number of shares of Common Stock issued and
sold under the Plan shall not exceed 5,000,000 shares. Shares of Common Stock
issued and sold under the Plan may be either authorized but unissued shares or
shares held in the Company's treasury. The number of shares of Common Stock
reserved for issuance under the Plan shall at no time be less than the maximum
number of shares which may be purchased at any time pursuant to outstanding
options. Shares of Common Stock covered by an Option that shall have been
exercised shall not again be available for an Option grant. If an Option shall
terminate or expire for any reason (including, without limitation, the
cancellation of an Option pursuant to Section 6.7 hereof) without being wholly
exercised, the number of shares to which such Option termination relates shall
again be available for grant hereunder.

            5.2 Adjustments. In the event of a reorganization, recapitalization,
stock split, stock dividend, combination of shares, merger or consolidation, or
the sale, conveyance, or other transfer by the Company of all or substantially
all of its property, or any other change in the corporate structure or shares of
the Company, pursuant to any of which events the then outstanding shares of
Common Stock are split up or combined, or are changed into, become exchangeable
at the holder's election for, or entitle the holder thereof to, other shares of
stock or any other consideration, or in the case of any other transaction
described in Section 424(a) of the Code, the Committee may change the number and
kind of shares (including by substitution of shares of another corporation)
subject to the Options and/or the Option Price of such shares in the manner that
it shall deem to be equitable and appropriate. In no event may any such change
be made to an Incentive Stock Option which would constitute a "modification"
within the meaning of Section 424(h)(3) of the Code without the consent of any
affected Optionee. In the event of any merger, consolidation, reorganization, or
similar corporate event in which shares of the Common Stock are to be exchanged
for payment of cash (the "Cash Consideration") the Committee may, in its
discretion, (i) make equitable adjustments as provided above, or (ii) cancel any
outstanding Option in exchange for payment in cash, if any, equal to the excess
of the Cash Consideration for the shares underlying such Option over the Option
Price for such shares.

                                   ARTICLE VI

                                     OPTIONS

            6.1 Grant of Option. An Option may be granted to any Eligible Person
selected by the Committee. The grant of an Option shall first be effective upon
the date it is approved by the Committee, except to the extent the Committee
shall specify a later date upon which the grant of an Option shall first be
effective. Each Option shall be designated, at the discretion of the Committee,
as an Incentive Stock Option or a Nonqualified Stock Option, provided that
Incentive Stock Options may only be granted to Eligible Persons who are
considered employees of the Company or any Subsidiary for purposes of Section
422 of the Code. The Company and the Optionee shall execute a Stock Option
Agreement which shall set forth such terms and conditions of the Option as may
be determined by the Committee to be consistent with the Plan, and which may
include additional provisions and restrictions that are not inconsistent with
the Plan.

            6.2 Maximum Limit. Notwithstanding anything elsewhere in the Plan to
the contrary, the maximum number of shares of Common Stock that may be subject
to Options granted to any Optionee during any one calendar year shall be 500,000
shares (subject to adjustment as provided in Section 5.2 hereof).

            6.3 Option Price. The Option Price shall be determined by the
Committee; provided, however, that the Option Price shall not be less than 100
percent of the Fair Market Value of a share of Common Stock on the trading date
immediately preceding the Date of Grant.

            6.4 Vesting; Term of Option. Unless otherwise specified by the
Committee in the Stock Option Agreement for an Optionee, an Option shall vest
and become exercisable in cumulative annual installments, each of which shall
relate to one-fifth of the number of shares of Common Stock originally covered
thereby (as may be adjusted in accordance with Section 5.2 hereof), on the
first, second, third, fourth and fifth anniversaries of the Date of Grant,
respectively, provided that the Optionee remains an Eligible Person on each such
anniversary. Notwithstanding the foregoing, the Committee, in its sole
discretion, may accelerate the exercisability of any Option at any time, and an
Option may become vested and exercisable in accordance with the provisions of
Articles VII and IX hereof. The period during which a vested Option may be
exercised shall be ten years from the Date of Grant, unless a shorter exercise
period is specified by the Committee in the Stock Option Agreement for an
Optionee.

            6.5 Option Exercise; Withholding. Subject to such terms and
conditions as shall be specified in a Stock Option Agreement, an Option may be
exercised in whole or in part at any time, with respect to whole shares only,
within the period permitted for the exercise thereof, and shall be exercised by
written notice of intent to exercise the Option with respect to a specified
number of shares delivered to the Company at its principal office, and payment
in full to the Company at said office of the amount of the Option Price for the
number of shares of the Common Stock with respect to which the Option is then


                                       5
<PAGE>

being exercised. Payment of the Option Price shall be made (i) in cash or by
cash equivalent, (ii) at the discretion of the Committee, in Common Stock that
has been held by the Optionee for at least six months (or such other period as
the Committee may deem appropriate for purposes of applicable accounting rules),
valued at the Fair Market Value of such shares determined on the date of
exercise, (iii) at the discretion of the Committee, by a delivery of a notice
that the Optionee has placed a market sell order (or similar instruction) with a
broker with respect to shares of Common Stock then issuable upon exercise of the
Option, and that the broker has been directed to pay a sufficient portion of the
net proceeds of the sale to the Company in satisfaction of the Option Price
(conditioned upon the payment of such net proceeds), (iv) at the discretion of
the Committee, by a combination of the methods described above, or (v) by such
other method as may be approved by the Committee and set forth in the Stock
Option Agreement. In addition to and at the time of payment of the Option Price,
the Optionee shall pay to the Company the full amount of all federal and state
withholding and other employment taxes required to be withheld in connection
with such exercise, in any manner consistent with the foregoing that is approved
by the Committee and set forth in the Stock Option Agreement.

            6.6 Limited Transferability of Option. All Options shall be
nontransferable except (i) upon the Optionee's death, by the Optionee's will or
the laws of descent and distribution or (ii) in the case only of Nonqualified
Stock Options on a case-by-case basis as may be approved by the Committee in its
discretion, in accordance with the terms provided below. Each Option Agreement
for a Nonqualified Stock Option shall provide that the Optionee may, during his
or her lifetime and subject to the prior approval of the Committee at the time
of proposed transfer, transfer all or part of the Option to a family member (as
defined below), provided that any such transfer is made by the Optionee for
estate and tax planning, donative purposes, or pursuant to a domestic relations
order, and no consideration (other than nominal consideration or interests in a
family partnership, family corporation or other family-related entity) is
received by the Optionee therefor. The transfer of a Nonqualified Stock Option
shall be subject to such other terms and conditions as the Committee may in its
discretion impose from time to time, including a condition that the portion of
the Option to be transferred be vested and exercisable by the Optionee at the
time of the transfer. Subsequent transfers of an Option transferred under this
Section 6.6 shall be prohibited other than by will or the laws of descent and
distribution upon the death of the transferee.

            For purposes hereof, a "family member" shall mean any child,
stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse,
sibling, niece, nephew, mother-in-law, father-in-law, son-in-law,
daughter-in-law, brother-in-law, or sister-in-law, including adoptive
relationships, any person sharing the participant's household (other than a
tenant or employee), a trust in which these persons have more than fifty percent
of the beneficial interest, a foundation in which these persons (or the
participant) control the management of assets, and any other entity in which
these persons (or the participant) own more than fifty percent of the voting
interests.

            No transfer of an Option by the Optionee by will or by laws of
descent and distribution shall be effective to bind the Company unless the
Company shall have been


                                       6
<PAGE>

furnished with written notice thereof and an authenticated copy of the will
and/or such other evidence as the Committee may deem necessary to establish the
validity of the transfer. During the lifetime of an Optionee, the Option shall
be exercisable only by him, except that, in the case of an Optionee who is
legally incapacitated, the Option shall be exercisable by his guardian or legal
representative.

            6.7 Cancellation, Substitution and Amendment of Options. The
Committee shall have the authority to effect, at any time and from time to time,
with the consent of the affected Optionees, (i) the cancellation of any or all
outstanding Options and the grant in substitution therefor of new Options
covering the same or different numbers of shares of Common Stock and having an
Option Price which may be the same as or different than the Option Price of the
cancelled Options or (ii) the amendment of the terms of any and all outstanding
Options.

                                   ARTICLE VII

                            ADDITIONAL RULES FOR ISOs

            7.1 Ten Percent Owners. Notwithstanding any other provisions of this
Plan to the contrary, in the case of an Incentive Stock Option granted to a Ten
Percent Owner, (i) the period during which any such Incentive Stock Option may
be exercised shall not be greater than five years from the Date of Grant and
(ii) the Option Price of such Incentive Stock Option shall not be less than 110
percent of the Fair Market Value of a share of Common Stock on the Date of
Grant.

            7.2 Annual Limits. No Incentive Stock Option shall be granted to an
Optionee as a result of which the aggregate fair market value (determined as of
the date of grant) of the stock with respect to which incentive stock options
are exercisable for the first time in any calendar year under the Plan, and any
other stock option plans of the Company, any Subsidiary or any parent
corporation, would exceed $100,000, determined in accordance with Section 422(d)
of the Code. This limitation shall be applied by taking options into account in
the order in which granted.

            7.3 Termination of Employment. An Incentive Stock Option may provide
that such Option may be exercised not later than three months following
termination of employment of the Optionee with the Company and all Subsidiaries,
subject to special rules relating to death and disability, as and to the extent
determined by the Committee to be consistent with the requirements of Section
422 of the Code and Treasury Regulations thereunder.

            7.4 Disqualifying Dispositions. If shares of Common Stock acquired
by exercise of an Incentive Stock Option are disposed of within two years
following the Date of Grant or one year following the transfer of such shares to
the Optionee upon exercise, the Optionee shall, within 10 days after such
disposition, notify the Company in writing of the date and terms of such
disposition and provide such other information regarding the disposition as the
Committee may reasonably require.


                                       7
<PAGE>

            7.5 Other Terms and Conditions. Any Incentive Stock Option granted
hereunder shall contain such additional terms and conditions, not inconsistent
with the terms of this Plan, as are deemed necessary or desirable by the
Committee, which terms, together with the terms of this Plan, shall be intended
and interpreted to cause such Incentive Stock Option to qualify as an "incentive
stock option" under Section 422 of the Code. A Stock Option Agreement for an
Incentive Stock Option may provide that such Option shall be treated as a
Nonqualified Stock Option to the extent that certain requirements applicable to
"incentive stock options" under the Code shall not be satisfied. An Incentive
Stock Option shall by its terms be nontransferable otherwise than by will or by
the laws of descent and distribution, and shall be exercisable during the
lifetime of an Optionee only by such Optionee.

                                  ARTICLE VIII

                             TERMINATION OF SERVICE

            8.1 Death. Unless otherwise provided and set forth in the Stock
Option Agreement, if an Optionee shall die at any time after the Date of Grant
and while he is an Eligible Person, the executor or administrator of the estate
of the decedent, or the person or persons to whom an Option shall have been
validly transferred in accordance with Section 6.6 hereof pursuant to will or
the laws of descent and distribution, shall have the right, during the period
ending one year after the date of the Optionee's death (subject to Sections 6.4
and 7.1 hereof concerning the maximum term of an Option), to exercise the
Optionee's Option to the extent that it was exercisable at the date of the
Optionee's death and shall not have been previously exercised. The Committee may
determine at or after grant to make any portion of his Option that is not
exercisable at the date of death immediately vested and exercisable.

            8.2 Disability. Unless otherwise provided by the Committee and set
forth in the Stock Option Agreement, if an Optionee's employment or other
service with the Company or any Subsidiary shall be terminated as a result of
his permanent and total disability (within the meaning of Section 22(e)(3) of
the Code) at any time after the Date of Grant and while he is an Eligible
Person, the Optionee (or in the case of an Optionee who is legally
incapacitated, his guardian or legal representative) shall have the right,
during a period ending one year after the date of his disability (subject to
Sections 6.4 and 7.1 hereof concerning the maximum term of an Option), to
exercise an Option to the extent that it was exercisable at the date of such
termination of employment or other service and shall not have been exercised.
The Committee may determine at or after grant to make any portion of his Option
that is not exercisable at the date of termination of employment or other
service due to disability immediately vested and exercisable.

            8.3 Termination for Cause. Unless otherwise provided by the
Committee and set forth in the Stock Option Agreement, if an Optionee's
employment or other service


                                       8
<PAGE>

with the Company or any Subsidiary shall be terminated for cause, the Optionee's
right to exercise any unexercised portion of an Option shall immediately
terminate and all rights thereunder shall cease. For purposes of this Section
8.3, termination for "cause" shall include, but not be limited to, embezzlement
or misappropriation of corporate funds, any acts of dishonesty resulting in
conviction for a felony, misconduct resulting in material injury to the Company
or any Subsidiary, significant activities harmful to the reputation of the
Company or any Subsidiary, a significant violation of Company or Subsidiary
policy, willful refusal to perform, or substantial disregard of, the duties
properly assigned to the Optionee, or a significant violation of any
contractual, statutory or common law duty of loyalty to the Company or any
Subsidiary. Notwithstanding the foregoing, in the event an Optionee is party to
an employment (or similar) agreement with the Company or any Subsidiary that
defines the term "cause," such definition shall apply for purpose of the Plan.
The Committee shall have the power to determine whether the Optionee has been
terminated for cause and the date upon which such termination for cause occurs.
Any such determination shall be final, conclusive and binding upon the Optionee.

            8.4 Other Termination of Service. Unless otherwise provided by the
Committee and set forth in the Stock Option Agreement, if an Optionee's
employment or other service with the Company or any Subsidiary shall be
terminated for any reason other than death, permanent and total disability or
termination for cause, the Optionee shall have the right, during the period
ending 90 days after such termination (subject to Sections 6.4 and 7.1 hereof
concerning the maximum term of an Option and subject to the terms of any
employment agreement between the Company or a Subsidiary and the Optionee), to
exercise an Option to the extent that it was exercisable at the date of such
termination and shall not have been exercised. For purposes of this Section 8.4,
an Optionee shall not be considered to have terminated employment or other
service with the Company or any Subsidiary until the expiration of the period of
any military, sick leave or other bona fide leave of absence, up to a maximum
period of 90 days (or such greater period during which the Optionee is
guaranteed reemployment either by statute or contract).

                                   ARTICLE IX

                                CHANGE IN CONTROL

            9.1 Change in Control. Unless otherwise provided by the Committee
and set forth in the Stock Option Agreement, upon a "change in control" of the
Company (as defined below), each outstanding Option, to the extent that it shall
not otherwise have become vested and exercisable, shall automatically become
fully and immediately vested and exercisable, without regard to any otherwise
applicable vesting requirement under Section 6.4 hereof; provided, however, that
no such vesting shall occur if provision has been made in writing in connection
with such transaction for (a) the continuation of the Plan and/or the assumption
of such Options by a successor corporation (or a parent or subsidiary thereof)
or (b) the substitution for such Options of new options covering the stock of a
successor corporation (or a parent or subsidiary thereof), with appropriate
adjustments as to the number and kinds of shares and exercise prices. In the
event of any


                                       9
<PAGE>

such continuation, assumption or substitution, the Plan and/or such Options
shall continue in the manner and under the terms so provided.

            9.2 Definition. For purposes of Section 9.1 hereof, a "change in
control" of the Company shall mean:

            (i) an acquisition subsequent to the date hereof by any person,
      entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the
      Securities Exchange Act of 1934, as amended (the "Exchange Act")) (a
      "Person"), of beneficial ownership (within the meaning of Rule 13d-3
      promulgated under the Exchange Act) of 30% or more of either (A) the then
      outstanding shares of Common Stock or (B) the combined voting power of the
      then outstanding voting securities of the Company entitled to vote
      generally in the election of directors (the "Outstanding Company Voting
      Securities"); excluding, however, the following: (1) any acquisition
      directly from the Company, other than an acquisition by virtue of the
      exercise of a conversion privilege unless the security being so converted
      was itself acquired directly from the Company, (2) any acquisition by the
      Company and (3) any acquisition by an employee benefit plan (or related
      trust) sponsored or maintained by the Company;

            (ii) a change in the composition of the Board such that during any
      period of two consecutive years, individuals who at the beginning of such
      period constitute the Board, and any new director (other than a director
      designated by a person who has entered into an agreement with the Company
      to effect a transaction described in paragraphs (i), (iii) or (iv) of this
      section) whose election by the Board or nomination for election by the
      Company's stockholders was approved by a vote of at least two-thirds of
      the directors then still in office who either were directors at the
      beginning of the period or whose election or nomination for election was
      previously so approved, cease for any reason to constitute at least a
      majority of the members thereof;

            (iii) the consummation of a merger, consolidation, reorganization or
      similar corporate transaction which has been approved by the stockholders
      of the Company, whether or not the Company is the surviving company in
      such transaction, in which outstanding shares of Common Stock are
      converted into (A) shares of stock of another company, other than a
      conversion into shares of voting common stock of the successor corporation
      (or a holding company thereof) representing 80% of the voting power of all
      capital stock thereof outstanding immediately after the merger or
      consolidation or (B) other securities (of either the Company or another
      company) or cash or other property;

            (iv) the approval by the stockholders of the Company of (A) the sale
      or other disposition of all or substantially all of the assets of the
      Company or (B) a complete liquidation or dissolution of the Company; or


                                       10
<PAGE>

            (v) the adoption by the Board of a resolution to the effect that any
      person has acquired effective control of the business and affairs of the
      Company.

                               STOCK CERTIFICATES

            10.1 Issuance of Certificates. Subject to Section 10.2 hereof, the
Company shall issue a stock certificate in the name of the Optionee (or other
person exercising the Option in accordance with the provisions of the Plan) for
the shares of Common Stock purchased by exercise of an Option as soon as
practicable after due exercise and payment of the aggregate Option Price for
such shares. A separate stock certificate or separate stock certificates shall
be issued for any shares of Common Stock purchased pursuant to the exercise of
an Option that is an Incentive Stock Option, which certificate or certificates
shall not include any shares of Common Stock that were purchased pursuant to the
exercise of an Option that is a Nonqualified Stock Option.

            10.2 Conditions. The Company shall not be required to issue or
deliver any certificate for shares of Common Stock purchased upon the exercise
of any Option granted hereunder or any portion thereof prior to fulfillment of
all of the following conditions:

            (i) the completion of any registration or other qualification of
      such shares, under any federal or state law or under the rulings or
      regulations of the Securities and Exchange Commission or any other
      governmental regulatory body, that the Committee shall in its sole
      discretion deem necessary or advisable;

            (ii) the obtaining of any approval or other clearance from any
      federal or state governmental agency which the Committee shall in its sole
      discretion determine to be necessary or advisable;

            (iii) the lapse of such reasonable period of time following the
      exercise of the Option as the Committee from time to time may establish
      for reasons of administrative convenience;

            (iv) satisfaction by the Optionee of all applicable withholding
      taxes or other withholding liabilities; and

            (v) if required by the Committee, in its sole discretion, the
      receipt by the Company from an Optionee of (i) a representation in writing
      that the shares of Common Stock received upon exercise of an Option are
      being acquired for investment and not with a view to distribution and (ii)
      such other representations and warranties as are deemed necessary by
      counsel to the Company.

            11.1 Effective Date. The Plan shall become effective upon its
adoption by the Board and its approval by the stockholders of the Company.

            11.2 Termination. The Plan shall terminate on the date immediately
preceding the tenth anniversary of the date the Plan is adopted by the Board.
The Board may, in its sole discretion and at any earlier date, terminate the
Plan. Notwithstanding the foregoing, no termination of the Plan shall in any
manner affect any Option theretofore granted without the consent of the Optionee
or the permitted transferee of the Option.

            11.3 Amendment. The Board may at any time and from time to time and
in any respect, amend or modify the Plan. Solely to the extent deemed necessary
or advisable by the Board, for purposes of complying with Sections 422 or 162(m)
of the Code or rules of any securities exchange or for any other reason, the
Board may seek the approval of any such amendment by the Company's stockholders.
Any such approval shall be by the affirmative votes of the stockholders of the
Company present, or represented, and entitled to vote at a meeting duly held in
accordance with applicable state law and the Certificate of Incorporation and
By-Laws of the Company. Notwithstanding the foregoing, no amendment or
modification of the Plan shall in any manner affect any Option theretofore
granted without the consent of the Optionee or the permitted transferee of the
Option.

                                   ARTICLE XII

                                  MISCELLANEOUS

            12.1 Employment or other Service. Nothing in the Plan, in the grant
of any Option or in any Stock Option Agreement shall confer upon any Eligible
Person the right to continue in the capacity in which he is employed by or
otherwise provides services to the Company or any Subsidiary. Notwithstanding
anything contained in the Plan to the contrary, unless otherwise provided in a
Stock Option Agreement, no Option shall be affected by any change of duties or
position of the Optionee (including a transfer to or from the Company or any
Subsidiary), so long as such Optionee continues to be an Eligible Person.

            12.2 Rights as Shareholder. An Optionee or the permitted transferee
of an Option shall have no rights as a shareholder with respect to any shares
subject to such Option prior to the purchase of such shares by exercise of such
Option as provided herein. Nothing contained herein or in the Stock Option
Agreement relating to any Option shall


                                       12
<PAGE>

create an obligation on the part of the Company to repurchase any shares of
Common Stock purchased hereunder.

            12.3 Other Compensation and Benefit Plans. The adoption of the Plan
shall not affect any other stock option or incentive or other compensation plans
in effect for the Company or any Subsidiary, nor shall the Plan preclude the
Company from establishing any other forms of incentive or other compensation for
employees of the Company or any Subsidiary. The amount of any compensation
deemed to be received by an Optionee as a result of the exercise of an Option or
the sale of shares received upon such exercise shall not constitute compensation
with respect to which any other employee benefits of such Optionee are
determined, including, without limitation, benefits under any bonus, pension,
profit sharing, life insurance or salary continuation plan, except as otherwise
specifically determined by the Board or the Committee or provided by the terms
of such plan.

            12.4 Plan Binding on Successors. The Plan shall be binding upon the
Company, its successors and assigns, and the Optionee, his executor,
administrator and permitted transferees.

            12.5 Construction and Interpretation. Whenever used herein, nouns in
the singular shall include the plural, and the masculine pronoun shall include
the feminine gender. Headings of Articles and Sections hereof are inserted for
convenience and reference and constitute no part of the Plan.

            12.6 Severability. If any provision of the Plan or any Stock Option
Agreement shall be determined to be illegal or unenforceable by any court of law
in any jurisdiction, the remaining provisions hereof and thereof shall be
severable and enforceable in accordance with their terms, and all provisions
shall remain enforceable in any other jurisdiction.

            12.7 Governing Law. The validity and construction of this Plan and
of the Stock Option Agreements shall be governed by the laws of the State of
Delaware.

                                    ARTICLE V

            5.1 Grant of Options. Each Nonemployee Director shall receive a

Option shall become 100 percent vested and exercisable on the first anniversary
of the Date of Grant, provided that the Optionee is a member of the Board on
such date. The period during which a vested Option may be exercised shall be ten
years from the Date of Grant.

            5.4 Option Exercise. An Option may be exercised in whole or in part
at any time, with respect to whole shares only, within the period permitted for
the exercise thereof, and shall be exercised by written notice of intent to
exercise the Option with respect to a specified number of shares delivered to
the Company at its principal office, and payment in full to the Company at said
office of the amount of the Option Price for the number of shares of the Common
Stock with respect to which the Option is then being exercised. Payment of the
Option Price shall be made (i) in cash or by cash equivalent, (ii) in Common
Stock valued at the Fair Market Value of such shares on the trading date


                                       3
<PAGE>

immediately preceding the date of exercise or (iii) by a combination of such
cash and such Common Stock.

            5.5 Limited Transferability of Option. All Options shall be
nontransferable except (i) upon the Optionee's death, by the Optionee's will or
the laws of descent and distribution or (ii) on a case-by-case basis as may be
approved by the Board in its discretion, in accordance with the terms provided
below. Each Option Agreement shall provide that the Optionee may, during his or
her lifetime and subject to the prior approval of the Board at the time of
proposed transfer, transfer all or part of the Option to a Permitted Transferee
(as defined below), provided that such transfer is made by the Optionee for
estate and tax planning purposes or donative purposes and no consideration
(other than nominal consideration) is received by the Optionee therefor. The
transfer of an Option shall be subject to such other terms and conditions as the
Board may in its discretion impose from time to time, including a condition that
the portion of the Option to be transferred be vested and exercisable by the
Optionee at the time of the transfer. Subsequent transfers of an Option
transferred under this Section 5.5 shall be prohibited other than by will or the
laws of descent and distribution upon the death of the transferee.

            For purposes hereof, a "Permitted Transferee" shall be any member of
the Optionee's immediate family or a charitable institution (each defined
below), or a trust for the exclusive benefit of such immediate family members
and/or charitable institution, or to a partnership or limited liability company
the equity interests of which are owned exclusively by the Optionee and/or one
or more members of his or her immediate family. For purposes of the preceding
definition, (i) the "immediate family" of the Optionee shall mean and include
the Optionee's spouse, any descendant of the Optionee or his or her spouse
(including descendants by adoption), and any descendant of either parent of the
Optionee (including descendants by adoption), and (ii) a "charitable
institution" shall mean and include any organization described in each of
section 170(b)(1)(A), 170(c), 2055(a) and 2522(a) of the Code, as well as any
charitable remainder trust created under section 664 of the Code, the income
beneficiary of which is a member of the Optionee's immediate family or a trust
or other entity described above in this Section 5.5.

            No transfer of an Option by the Optionee by will or by laws of
descent and distribution shall be effective to bind the Company unless the
Company shall have been furnished with written notice thereof and an
authenticated copy of the will and/or such other evidence as the Board may deem
necessary to establish the validity of the transfer. During the lifetime of an
Optionee, the Option shall be exercisable only by him, except that, in the case
of an Optionee who is legally incapacitated, the Option shall be exercisable by
his guardian or legal representative.

                             TERMINATION OF SERVICE

            6.1 Death. If an Optionee shall die at any time after the Date of
Grant and while he is a member of the Board, the executor or administrator of
the estate of the decedent, or the person or persons to whom an Option shall
have been validly transferred in accordance with Section 5.5 hereof pursuant to
will or the laws of descent and distribution, shall have the right, during the
period ending one year after the date of the Optionee's death (subject to
Section 5.3 hereof concerning the maximum term of an Option), to exercise the
Optionee's Option to the extent that it was exercisable at the date of such
Optionee's death and shall not have been previously exercised.

            6.2 Disability. If an Optionee's service as a member of the Board
shall be terminated as a result of his permanent and total disability (within
the meaning of Section 22(e)(3) of the Code) at any time after the Date of
Grant, the Optionee (or in the case of an Optionee who is legally incapacitated,
his guardian or legal representative) shall have the right, during a period
ending one year after the date of his disability (subject to Section 5.3 hereof
concerning the maximum term of an Option), to exercise an Option to the extent
that it was exercisable at the date of such Optionee's disability and shall not
have been previously exercised.

            6.3 Removal for Cause. If an Optionee shall be removed from the
Board for cause, the Optionee's right to exercise any unexercised portion of an
Option shall immediately terminate and all rights thereunder shall cease. An
Optionee shall be considered to have been removed for "cause" for purposes of
this Section 6.3 when he shall have been removed from the Board by the
stockholders of the Company for cause in accordance with applicable state law
and the Certificate of Incorporation and By-Laws of the Company.

            6.4 Other Termination of Service. If an Optionee's service as a
member of the Board shall be terminated for any reason other than death,
permanent and total disability or removal for cause, the Optionee shall have the
right, during the period ending 90 days after such termination (subject to
Section 5.3 hereof concerning the maximum term of an Option), to exercise an
Option to the extent that it was exercisable at the date of such termination of
service and shall not have been previously exercised.

defined below), each outstanding Option, to the extent that it shall not
otherwise have become exercisable, shall become fully and immediately vested and
exercisable (without regard to the otherwise applicable installment exercise
requirement under Section 5.3 hereof).

election or nomination for election was previously so approved, cease for any
reason to constitute at least a majority of the members thereof;

            (iii) the approval by the stockholders of the Company of a merger,

      Insert No. 1

      The Bank shall provide the following credit facilities to the Borrower:

      a. $8,000,000.00 Term Loan

            (i) Subject to the terms and conditions herein, as of March 31, 1998
("Effective Date"), Bank agrees to lend to the Company, and the Company agrees
to borrow from Bank a term loan in the principal amount of Eight Million Dollars
($8,000,000.00) (the "Term Loan").

            (ii) The Term Loan will be evidenced by a single Term Note ("1998
Term Note") substantially in the form of Exhibit A, annexed here to, which
Borrower shall execute and unconditionally deliver to the Bank on the Effective
Date (defined below) and which shall have the blanks completed to conform
herewith and which will:

                  (A)   Be dated the Effective Date.

                  (B)   Be payable to the order of Bank in the principal amount
                        of Eight Million Dollars ($8,000,000.00).

                  (C)   Except as otherwise provided therein, accrue interest
                        payable at all times prior to an Event of Default
                        (defined below), computed on the basis of a 360 day year
                        for the actual number of days elapsed, at the fixed rate
                        of 8.39% per annum.

                  (D)   84 consecutive equal monthly payments of $126,249.81
                        principal and interest each, which is an amount required
                        to fully amortize the principal amount of the 1998 Term
                        Note with
<PAGE>

                        interest over the amortization period of the Note, which
                        is seven years. The then unpaid principal balance of the
                        1998 Term Note, if any, plus any unpaid accrued
                        interest, shall be all due and payable on April 1, 2005
                        ("Maturity").

                  (E)   The Borrower shall have the option of paying the
                        principal sum outstanding under the 1998 Term Note to
                        Bank in advance of the Maturity Date, in whole or in
                        part, at any time and from time to time, upon written
                        notice received by the Bank at least three (3) business
                        days prior to making such payment; provided, however,
                        that, together with such prepayment, Borrower shall pay
                        to the Bank the prepayment premium provided for in the
                        1998 Term Note together with all accrued and unpaid
                        interest and expenses owing pursuant to the 1998 Term
                        Note together with the exit referred to in clause (iii)
                        below.

            (iii) If Borrower pays any principal outstanding under the 1998
Term Note before the scheduled payment thereof for any reason (including
acceleration thereof as the result of an event of default), then an exit fee
shall be due from the Borrower to the Bank in addition to any prepayment premium
which may be due under the 1998 Term Note. In such event, the exit fee shall
equal (a) the amount by which the prepaid principal is greater than Borrower's
Excess Cash Flow (defined below), multiplied by two percent (2%). Borrower
acknowledges that such exit fee shall be liquidated damages and not a penalty,
and shall be due and paid in addition to the then outstanding principal, accrued
interest and other charges owing under this Agreement and any of the other
related documents which Borrower is obligated to Bank (including the prepayment
premium due under the 1998 Term Note).

            As used herein, "Excess Cash Flow" means for the twelve (12) months
ended as of the calendar month immediately preceding the date on which a
principal prepayment is made ("Measuring Period"), Borrower's Net Income
(defined below) for such period plus (A) the sum of depreciation and
amortization to the extent deducted in determining such Net Income minus (B)
Capital Expenditures (defined below), made during such period unless the Capital
Expenditures are financed by Bank expressly for the purpose of financing the
Capital Expenditures, minus (C) any payments on account of borrowed money by
Parent (defined below) and/or Borrower (other than payment with respect to
indebtedness outstanding under the 1998 Grid Note defined below) made during
such period minus (D) principal payments on capitalized lease obligations made
during such period minus (E) distributions, dividends and amounts paid or
accrued for the repurchase of stock by the Borrower during the Measuring Period,
all as determined in accordance with GAAP (defined below) used in the
preparation of Borrower's financial statements on a consistent basis.

      b. $10,000,000.00 Line of Credit.

            (i) Subject to the terms and conditions of this Agreement, Bank
shall establish on the Effective Date for the benefit of Borrower a
discretionary line of credit ("Line of Credit") in the maximum principal amount
equal to the lesser of Ten Million Dollars ($10,000,000.00) or the then existing
Borrowing Base (the "Maximum Credit"). Borrowing Base is defined below. Loans
under the Line of Credit are discretionary with Bank and conditioned upon prior
approval by Bank.

            (ii) The fact that a particular loan request pursuant to the Line of
Credit is disapproved by Bank shall have no effect on the Line of Credit, nor on
Borrower's rights to make future requests for loans under the Line of Credit,
nor on Borrower's obligation to pay the 1998 Grid Note (defined below) and any
other indebtedness of Borrower to Bank in full. Provided that Bank gives
approval to the requested borrowing, Borrower may borrow, repay and reborrow
under the Line of Credit, so long as the unpaid principal balance of the Grid
Note does not exceed the Maximum Credit.

            (iii) Requests for a loan under the Line of Credit may be oral (in
person or by telephone) or in writing from an authorized person named in the
1998 Grid Note ("Authorized Person") and shall specify a date which shall be a
business day in New York State and the amount to be borrowed. Borrower will be
bound by such instructions. Borrower hereby indemnifies and holds Bank harmless
from any liability (including Bank's reasonable attorneys' fees) which may arise
as a result of Bank's reliance on telephone requests for borrowing and/or
prepayment instructions from any person identifying himself as an Authorized
Person. Each borrowing shall be in the minimum principal amount of $25,000.00 or
a $5,000.00 integral multiple thereof, except for a borrowing in a lesser amount
equal to the unused portion of the Maximum Credit.

            (iv) Each Approved Loan shall be processed by debiting the Line of
Credit and crediting Borrower's checking account with Bank for the amount of the
Approved Loan or by forwarding or applying the Approved Loan proceeds as
otherwise agreed by Bank and Borrower. The Approved Loan shall be deemed made
immediately upon the crediting of the Approved Loan proceeds to Borrower's
checking account with Bank or forwarding or applying the Approved Loan proceeds
as otherwise agreed by Bank and Borrower. Each Approved Loan, together with the
unpaid principal balance of all previous Approved Loans, shall be automatically
refinanced and consolidated into one loan, referred to below as the
"Consolidated Loan."

            (v) The Consolidated Loan is payable on demand and shall be
evidenced by an Amended and Restated Grid Note (with blanks appropriately
completed) (the "1998 Grid Note"), which Borrower shall execute and deliver to
Bank on the Effective Date. The 1998 Grid Note shall be in the form of Exhibit
B, with blanks appropriately completed.


                                       R-3
<PAGE>

            (vi) All outstanding amounts under the Line of Credit, (except as
specifically provided in the Grid Note), shall bear interest until paid in full
at the floating rate of one-quarter percent (.25%) above the Bank's prime rate.
Interest shall be calculated based on actual days elapsed divided by a year of
three hundred sixty (360) days. Changes in the rate of interest applicable to
the Grid Note shall become effective automatically and without notice at the
time of changes in the Bank's prime rate.

            (vii) Payments of all accrued interest under the 1998 Grid Note
shall be made on the first day of each month commencing May 1, 1998 unless
payment of the 1998 Grid Note is sooner demanded by Bank, in which case all
accrued interest shall be immediately due and payable in full. Principal
outstanding pursuant to the 1998 Grid Note shall be due and payable in full at
any time upon demand by Bank. In the event Borrower becomes aware, or receives
notice (oral or written) from Bank, that principal amounts outstanding under the
Line of Credit exceed the Maximum Credit at any time, Borrower promptly shall
make a principal payment to Bank sufficient to reduce outstanding principal
amounts to the Maximum Credit without the necessity of a demand by Bank.

            (viii) As used in this Agreement, the following definitions shall
apply:

            "Accounts" all accounts, contract rights, chattel paper, instruments
and documents, whether now owned or hereafter created or acquired by Borrower or
in which Borrower now has or hereafter acquires any interest.

            "Borrowing Base" means, on any date, (a) the sum of (i) eighty
percent (80%) of Borrower's Eligible Accounts and (ii) forty percent (40%) of
Borrower's Eligible Inventory (up to a maximum amount of $8,500,000.00), less
(b) the sum of (i) the unpaid principal amount outstanding under the 1998 Term
Note and (ii) the outstanding stated amount of all outstanding letters of credit
which were issued by the Bank (after approval by the Bank for the account of the
Borrower or CVC, Inc. ("Parent") and that are outstanding and (iii) any deposits
or advances from customers to the extent that such customers are account debtors
with respect to any Eligible Accounts. For purposes of this calculation,
Eligible Receivables and Eligible Inventory shall be as set forth in the most
recent Borrowing Base Certificate delivered to Bank.

            "Effective Date" means March 31, 1998.

            "Eligible Accounts" an Account arising in the ordinary course of
Borrower's business from the sale of goods or rendition of services, provided

            installation of tools shall be in existence no more than 180 days
            from the date of shipment;


                                       R-4

      (b)   The Account arose (i) from the performance of services by Borrower
            that have been fully and satisfactorily performed or (ii) from the

            and finally accepted without dispute by the account debtor without
            return, rejection, loss or damage and as to which Borrower or the
            Bank has possession of a shipping or delivery receipt;

      (c)   The Account is a legal, valid and binding obligation of the Account
            Debtor and is not subject to any offset, counterclaim, defense,
            credit, allowance or adjustment except a discount for prompt
            payment, or to any dispute, objection or complaint by the Account
            Debtor concerning his, her or its liability on the Account;

      (d)   The Account arose in the ordinary course of Borrower's business and
            no notice of bankruptcy, insolvency, failure, suspension or

            Debtor has been received by Borrower or the Bank;

      (e)   The account debtor is not an affiliate (defined below) of Borrower
            (other than Seagate Technology) or a supplier (or an affiliate of a
            supplier) of goods or services to Borrower;

      (f)   The Account is not an employee accounts receivable, bill and hold
            accounts receivable (i.e., accounts relating to goods not yet
            shipped but invoiced), uncollectible accounts receivable, accounts
            receivable arising from progressive billings (i.e., accounts
            receivable from billings for work performed on a partially completed
            contract), accounts receivable arising from guaranteed sales with
            buy back provisions (i.e., sales in which the Borrower is obligated
            to repurchase inventory or merchandise sold to customers), accounts

            thereof (unless assignment and notice thereof is effected in

      (g)   The full amount reflected on Borrower's records and on any invoice
            delivered to the Bank relating to the Account is owing to Borrower
            and no partial prepayments thereon have been made.

      (h)   Each representation and warranty with respect to the Account made by
            Borrower to the Bank in any security agreement executed by Borrower
            is true and complete;

      (i)   The Account is subject to the perfected first priority security
            interest of the Bank and to no other security interest, lien,
            assignment or encumbrance of any kind; and


                                       R-5
<PAGE>

      (j)   The Bank has not notified Borrower that the Account or the Account
            Debtor, in the Bank's reasonable judgment, is unsatisfactory.

            "Eligible Inventory' means all first quality inventories of finished
products, work-in-process inventory and raw materials owned by the Borrower,
valued at the lower of cost (on a FIFO basis) or market, minus all perishable or
non-saleable inventories and such reserves as Borrower has historically
established, including, but not limited to, (a) shrinkage reserves, (b) markdown
reserves, and (c) reserves which restore standard costs to actual costs. Neither
so-called mold inventories or inventories on consignment, (except that with
respect to consignments, Eligible Inventory shall include inventory shipped to
customers at sites located in the United States for evaluation by the customer,
provided that no more than 75 days elapse from the date of shipment and further
provided that the aggregate value of such Eligible Inventory on consignment does
not exceed $2,500,000.00), are Eligible Inventories and all such inventories
shall be excluded from the calculation thereof. Eligible Inventories must arise
from the Borrower's ordinary course of business as it exists on the date of this
Agreement, must at all times be subject to the perfected, first priority
security interest of Bank and no other lien, must be located on Borrower's
premises within the United States (which are covered by a landlord/mortgagee
waiver acceptable to the Bank), must conform in all respects to warranties
contained in this Agreement and all security or other related agreements and
documents, and must not be subject to a licensing agreement with third parties
unless Bank shall have received consents or acknowledgements or other assurances
satisfactory to the Bank from such third parties as may be deemed necessary or
desirable to facilitate Bank's realization upon such inventory. Any inventory
subject to an Eligible Account shall also not constitute Eligible Inventory. The
calculation of Eligible Inventory must be satisfactory to the Bank in its
reasonable discretion.

            (ix) Borrower also will submit to Bank within thirty (30) days after
the end of each calendar month a Borrowing Base Certificate reporting on the
Borrowing Base as of the end of the previous month together with all supporting
documentation requested by Bank and a monthly backlog report. Each Borrowing
Base Certificate shall be in form satisfactory to the Bank and certified to Bank
by Borrower's Chief Financial Officer. Borrower will also, within forty-five
(45) days of the end of each of its first three fiscal quarters, provide Bank
with a certificate executed by its Chief Financial Officer, stating that he has
read this Agreement, knows its contents and that to his knowledge, Borrower is
in compliance with all financial covenants contained in this Agreement, and no
Event of Default has occurred under the Agreement, and no conditions exists,
which, with notice, lapse of time or both, would constitute an Event of Default
under this Agreement. The certificate shall also show the computations required
to establish Borrower's compliance with each financial covenant during the
period covered by the certificate. Borrower shall also provide Bank with such
additional financial and other information as Bank shall reasonably, from time
to time, request.

            (x) Bank may perform full field audits of Borrower's accounts
receivable and inventories at Borrower's expense twice a year. Bank reserves the
right, in its sole


                                       R-6
<PAGE>

discretion and at its own expense, to perform field audits of Borrower's
accounts receivable and inventories more than twice per year.

            (xi) The Line of Credit will terminate on the demand by Bank of
amounts outstanding under the 1998 Grid Note. Bank may also terminate Borrower's
right to make requests for loans under the Line of Credit at any time by giving
Borrower written notice of termination without making a demand for payment of
the 1998 Grid Note. The giving of such notice by Bank shall not effect Bank's
rights under this Agreement or under the 1998 Grid Note or under any other
agreement, instrument or document made by Borrower with or in favor of Bank, nor
on Borrower's obligation to pay the 1998 Grid Note in full according to its
terms.

      c. $2,000,000.00 Loan Limit.

            (i) Subject to the terms and conditions of this Agreement, the Bank
hereby establishes for the benefit of the Borrower a discretionary offering
basis loan limit ("Loan Limit") in the maximum principal amount outstanding at
any one time of Two Million Dollars ($2,000,000.00) less the aggregate principal
amount (or in the case of an operating lease payment amount) due under all
capital and operating leases existing between Borrower and M&T Financial
Corporation. Under the Loan Limit, an authorized officer of the Bank, in his
sole discretion, may make advances to Borrower under the Loan Limit on the terms
specified below. Borrower acknowledges that such officer may refuse to make any
advances under the Loan Limit to Borrower for any reason, or for no reason
whatsoever.

            (ii) Provided that all of the conditions for advances contained
herein are satisfied, including approval of a requested advance, advances under
the Loan Limit will be made from time to time at the request of the Borrower by
credits to the Borrower's accounts at the Bank.

            (iii) Unless extended by the Bank in writing in its sole discretion,
the Loan Limit will be available until terminated by Bank upon written notice to
the Borrower. Borrower acknowledges that Bank may terminate the Loan Limit at
any time in its sole discretion.

            (iv) With each advance under the Loan Limit, the Borrower shall
execute a term note evidencing such indebtedness to the Bank (each such note, a
"Loan Limit Note"). Each Loan Limit Note shall be in substantially the form of
Exhibit C attached hereto. Each such note, shall be dated the date the Borrower
executes the note, be payable to the order of Bank, be in the principal amount
of the advance and provide for interest accruing, prior to an Event of Default,
at the variable rate equal to the Bank's prime rate plus one-half percent
(1/2%). Each Loan Limit Note shall further provide that, unless sooner
accelerated, the original principal amount evidenced thereby shall be repayable
in such number of months as may be selected by Bank which shall not be less than
thirty-six (36) months nor more than sixty (60) months. Accrued interest under
each Loan Limit Note shall be due on


                                       R-7
<PAGE>

the first day of each calendar month, with the first interest payment due on the
first day of the first month following the date on which the note is executed
and continuing thereafter until the note is paid in full. All remaining
principal and accrued interest shall be due and payable in full on the Loan
Limit Note's maturity date.

      d. Up-Front Fee. On the Effective Date, Borrower shall pay Bank a facility
fee of $50,000 ("Up-Front Fee"), which shall be fully earned as of the Effective
Date and upon payment thereof shall be non-refundable.

      Insert No. 2

complete copy of Amendment No. 2 to Registration Statement (File No. 333-38057)
filed by Parent with the Securities and Exchange Commission on January 16, 1998
and such Registration Statement (including the prospectus contained therein)
does not, and in the future neither the Registration Statement nor any
supplement nor amendment thereto, will contain any untrue statement of a
material fact or omit to state a material fact required to be stated or
incorporated by reference therein or necessary to make the statements therein
not misleading (and in the case of the prospectus, not misleading in light of
the circumstances under which they were made).

      c. Subsidiaries and Affiliates. The Borrower is a wholly-owned subsidiary
of the Parent and neither Borrower nor Parent has any subsidiaries or
affiliates, except those listed in the attached "Schedule of Permitted
Subsidiaries and Affiliates." Parent's sole asset is the capital stock of
Borrower. Borrower is not a party to any material transaction with any affiliate
other than as described in the footnotes to the Borrower's September 30, 1997
financial statements and all such transactions are in the ordinary course of
business and upon fair and reasonable terms not materially less favorable than
Borrower could obtain or become entitled to in an arm's length transaction with
an entity that is not an affiliate.

      As used herein, the following definitions apply:

      "affiliates" means any entity which directly or indirectly, or through one
or more intermediaries, controls or is controlled by or is under common control
with Parent, Borrower or any subsidiary of Parent or Borrower.

      "control," "controlled by" or "under common control" means, but is not
limited to, the beneficial ownership (as defined in Rule 13(d) promulgated by
the Securities Exchange Commission pursuant to Section 13(d) of the Securities
Exchange Act of 1934, as amended) of ten percent (10%) or more of the
outstanding shares of the capital stock of any corporation having any voting
power for the election of directors (whether or not at the same time stock of
any other class or classes has or might have voting power by reason of the
happening of any contingency) or ten percent (l0%) or more of any equity
interest in any non-corporate entity, or any other interest through which the
power to direct the management or policies of a person may be exercised.

      d. Capitalization. All of the outstanding shares and other equity
interests of Parent and Borrower are duly authorized, validly issued and fully
paid and were issued in compliance with all federal, state and foreign
securities laws. Except for the Borrower's right to repurchase stock held by its
employees under certain circumstances and the Borrower's Series B preferred
stock repurchase obligations under its Certificate of Incorporation, there is no
existing contract, debenture, security, right, option, warrant, call or similar
commitment of any character calling for or relating to the purchase, repurchase,
redemption or retirement of any shares or other equity securities of the
Borrower or Parent.

      e. Leases. The Borrower has undisturbed peaceable possession under all
leases under which it is operating, none of which contain unusual or burdensome
provisions that may materially affect the operations of the Borrower, and all
such leases are in full force and effect.

      f. Existing Indebtedness. Except as disclosed in the attached "Schedule of
Permitted Indebtedness," neither Parent nor Borrower has any outstanding
indebtedness or contingent liabilities (including, without limitation,
"off-balance sheet" liabilities) other than those liabilities disclosed in the
Borrowers' balance sheet, dated as of December 31, 1997, and wages, salary,
trade payables and operating leases incurred in the ordinary course of business
since such date. Without limiting the foregoing, neither Parent nor Borrower is
an account party with respect to any letters of credit other than those issued
by Bank. Borrower shall not, without Bank's prior written consent, modify the
terms of any of its existing long-term debt or make any principal payments on
any long-term debt, including, without limitation, any debt owed to Nikko Tecno
Co., Inc. ("Nikko Debt") (other than debt to Bank) at any time for any reason
(whether before or after maturity thereof) or unscheduled payments of interest
on Nikko Debt.

      g. ERISA Plans. The Borrower does not sponsor, maintain, contribute to or
have any liability with respect to any retirement, pension, profit sharing or
other plan that is subject to the Employee Retirement Security Act of 1974, as
amended ("ERISA"), except for the plans described in the attached "Schedule of
Benefit Plans" (all such plans being referred to as "ERISA Plans"), true and
complete copies of which have been provided to Bank. Neither the Borrower nor
any ERISA affiliate has withdrawn from or terminated any retirement, pension,
profit sharing or other plan subject to ERISA and neither of them are a member
of or contribute to any multi-employer plan or multiemployer plan. No action,
event or transaction has occurred that could give rise to a lien, security
interest or encumbrance on the assets of Parent or Borrower as a result of the
application of relevant provisions of the Internal Revenue Code of 1986, as
amended ("IRC"), or ERISA, and the ERISA Plans are in material compliance with
all requirements of the IRC and ERISA and none of the ERISA Plans are
underfunded.

      h. Margin Securities. No proceeds of any loans made pursuant to this
Agreement have been or will be used for the purpose of purchasing or carrying
Margin Securities as defined in Regulation U of the Federal Reserve Board.

all patents, trademarks, service marks, tradenames, copyrights, licenses,

conduct of its business as now conducted without any material conflict with the
rights of others.

and documents executed by the Borrower with or in favor of the Bank or M&T Real

      e. There shall exist no litigation pending or threatened in any court or

and all related agreements, instruments and documents.

      g. All of the information provided by or on behalf of Borrower to Bank

                                      R-19
<PAGE>

document be provided and Borrower's failure to provide such document or
documents to Bank after the Effective Date shall, after twenty (20) days (or
less if reasonable under the circumstances) advance notice to Borrower, at
Bank's option, constitute an Event of Default under this Agreement. The
requirement that the Borrower deliver to the Bank any loan document called for

      14. This Agreement supersedes and replaces the Term Loan Agreement dated

      16. Anything contained in any Loan Document to the contrary
notwithstanding, if any provision of any Loan Document provides for notice to
Borrower which is contrary to the notice provision contained in Section 8 of the
preprinted form of this Agreement ("Section 8"), the terms of Section 8 shall
control. Anything contained in any Loan Document to the contrary
notwithstanding, if any provision of any Loan Documents call for delivery of
financial statements, borrowing base certificates, certificates of no default or
other financial information which conflicts with, or is in addition to, the
provisions of Section 2j of this Agreement and/or Insert 1 b(ix) of the Addendum
to this Agreement (collectively, "Required Financial Provisions"), the terms of
the Required Financial Provisions shall control, and the conflicting or
additional requirements shall be deemed null and void.

      17. Anything contained in this Agreement and/or in any Loan Document to
the contrary notwithstanding, Bank may automatically debit any account of
Borrower maintained at Bank for any amount (including but not limited to
principal, interest and/or late charges), which becomes due Bank under this
Agreement and/or under any Note or otherwise, when due.

      18. Borrower and Bank acknowledge and agree that anything contained in
Insert 1c of this Addendum (which provides for a $2,000,000.00 Loan Limit), to
the contrary notwithstanding, Borrower shall have no rights to request to borrow
under the Loan Limit and Bank shall have no obligations under the Loan Limit. As
of the Closing Date, the Loan Limit provisions of insert 1c and Exhibit C to
this Agreement shall be deemed deleted.

      IN WITNESS WHEREOF, Borrower and Bank have executed this Rider on the date
indicated in the acknowledgement, effective as of March 31, 1998.

[LOGO] M&T Bank
       Manufactures and Traders Trust Company

                                    TERM NOTE

Rochester, New York as of March 31, 1998                           $8,000,000.00

BORROWER: CVC PRODUCTS, INC.

a(n) |_| individual(s) |_| partnership |X| corporation |_| trust |_| __________
organized under the laws of Delaware

Address of residence/chief executive office: 525 Lee Road, Rochester, New York
14606

BANK: MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking corporation
      with its principal banking office at One M&T Plaza, Buffalo, NY 14240.

Promise to Pay. For value received, Borrower promises to pay to the order of the
Bank, on the dates set forth below, the principal sum of EIGHT MILLION and
00/100 Dollars ($8,000,000.00) (the "Principal") plus interest as agreed below
and all reasonable fees and costs (including without limitation reasonable
attorneys' fees and disbursements whether for internal or outside counsel) the
Bank incurs in order to collect any amount due under this Note, to negotiate or
document a workout, or restructuring, or to preserve its rights or realize upon
any guaranty or other security for the payment of this Note ("Expenses").

Interest. The unpaid Principal balance of this Note shall earn interest
calculated on the basis of a 360-day year for the actual number of days of each
year (365 or 366) from and including the date the proceeds of this Note were
disbursed to, but not including, the date all amounts hereunder are paid in
full, at a rate per year which shall on each day be:

|X|   8.39%

|_|   equal to the rate in effect on that day as the rate announced by the Bank
      as its prime rate of interest.

|_|   _______% above the rate in effect on that day as the rate announced by the
      Bank as its prime rate of interest.

If no rate is specified above, interest shall accrue at the Maximum Legal Rate
(defined below).

Maximum Legal Rate. It is the intent of the Bank and Borrower that in no event
shall interest be payable at a rate in excess of the maximum rate permitted by
applicable law (the "Maximum Legal Rate"). If this Note is for a personal loan
of less than $2,500,000 and is secured primarily by a one- to four-family
residence, the interest rate shall not exceed 16%. Solely to the extent
necessary to prevent interest under this Note from exceeding the Maximum Legal
Rate, any amount that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically canceled, and, if received by the Bank, shall be refunded to
Borrower.

Default Rate. If an Event of Default (defined below) occurs, the interest rate
on the unpaid Principal shall immediately be automatically increased to 5% per
year above the otherwise applicable rate per year.

Repayment of Principal and Interest; Late Charge. Payments shall be made in
immediately available United States funds at any banking office of the Bank.
Interest will continue to accrue until payment is actually received. If payment
is not received within five days of its due date, Borrower shall pay a late
charge equal to the greatest of (a) $50.00, (b) 5% of the delinquent amount or
(c) the Bank's then current late charge as announced from time to time. If this
Note is secured by a one- to six-family owner-occupied residence, the late
charge shall equal 2% of the delinquent amount and shall be payable if payment
is not received within fifteen days of its due date. Payments may be applied in
any order in the sole discretion of the Bank but, prior to default, shall be
applied first to past due interest, Expenses, late charges and principal, then
to current interest, Expenses, late charges and principal, and last to remaining
principal.

The Maturity Date of this Note is April 1, 2005.

|_|   Borrower shall pay the entire Principal on the Maturity Date. In addition,
      until the outstanding Principal is paid in full, payments of all accrued
      and unpaid interest in amounts which will vary will become due and payable
      on the _______ day of each:

      |_| month  |_| quarter  |_| year commencing on ____________, 19__.

|X|   Borrower shall pay 84 consecutive level |X| monthly |_| quarterly |_|
      annual installments consisting of both Principal and interest, amortized
      over a period of 7 years, commencing on May 1, 1998 and also due on the
      first day of each month thereafter. Each payment will equal $126,249.81
      except that the last payment will equal all remaining amounts due under
      this Note.

      IF A PAYMENT IS RECEIVED AFTER THE DUE DATE, MORE INTEREST WILL BE DUE
      THAN PLANNED AND LESS MONEY APPLIED TO PRINCIPAL. REPEATED LATE PAYMENTS
      WILL CAUSE AN UNEXPECTED PRINCIPAL BALANCE 10 REMAIN UNPAID AT THE END OF
      THE TERM.

CLB-102 (12/94) 360-Day Base

<PAGE>

Prepayment Premium. During the term of this Note, Borrower shall have the option
of paying the Principal to the Bank in advance of the Maturity Date, in whole or
in part, at any time and from time to time. Upon making any prepayment of the
Principal Sum in whole, Borrower shall pay to the Bank all interest and Expenses
owing pursuant to this Note and remaining unpaid. Each partial prepayment of
Principal shall be applied in inverse order of maturity to the principal
included in the installments provided for in the paragraph of the Note captioned
"Repayment of Principal and Interest."

                              BY CVC PRODUCTS, INC.
                                   IN FAVOR OF
                     MANUFACTURERS AND TRADERS TRUST COMPANY

      This RIDER, to a certain $8,000,000 Term Note, dated as of March 31, 1998,
is made by CVC PRODUCTS, INC. ("Borrower") in favor of MANUFACTURERS AND TRADERS
TRUST COMPANY ("Bank"). This Rider is an integral part of the Term Note.

      Insert No. 1. - The following is the addition to the first sentence of the
"Prepayment Premium" section of the preprinted form of this Note:

            "upon three days prior written notice received by Bank, provided
            however that the prepayment is accompanied by a Redemption Premium
            calculated as follows: The Redemption Premium shall be equal to the
            amount by which the sum of the Discounted Values (as determined
            below) of the Prepaid Installments of principal and interest on the
            Note exceeds the amount of the prepayment; but this amount shall
            never be less than 1 % of the principal amount prepaid. Bank shall
            in good faith determine such Discounted Values by discounting all of
            the Prepaid Installments of principal and interest at the Applicable
            Treasury Rate (as determined below) from the date on which the
            prepayment is made through the respective scheduled payment dates.
            The Applicable Treasury Rate to be applied shall be the yield which
            is imputed from linear interpolation from current daily yields of
            U.S. Treasury obligations having maturities as close as practicable
            to the Average Life to Stated Maturity (as determined below) of the
            Prepaid Installments of principal (as of the third day prior to the
            date on which the prepayment is made) as published in the Federal
            Reserve Statistical Release H.15 (519) or if such yield is not so
            published, a similar rate based upon a comparable index as
            determined by Bank. The Average Life to Stated Maturity of the
            Prepaid Installments of principal shall be the number of months
            obtained by determining (A) the sum of the products obtained by
            multiplying (i) the amount of each Prepaid Installment of principal
            by (ii) the number of months from the date the prepayment is made
            through the scheduled payment date for such Prepaid Installment of
            principal and (B) dividing such sum by the sum of the Prepaid
            Installments of principal.

            Upon making any prepayment of the unpaid principal balance of this
            Note in full, Borrower shall also pay Bank all accrued interest and
            Expenses owing on this Note. Each partial principal prepayment shall
            be applied in inverse order
<PAGE>

            of maturity to the principal included in the installments provided
            for in the preprinted portion of this Note labelled "Repayment of
            Principal and Interest; Late Charge.

            In the event the Maturity Date of this Note is accelerated following
            an Event of Default by the Borrower, any tender of payment of the
            amount necessary to satisfy the entire indebtedness made after such
            Event of Default shall be expressly deemed a voluntary prepayment.
            In such case, to the extent permitted by law, Bank shall be entitled
            to the amount necessary to satisfy the entire indebtedness, plus the
            appropriate prepayment premium calculated in accordance with this
            Section."

      Insert No. l.A.

      the Loan Agreement of even date herewith between Bank and Borrower, as
amended, extended and replaced

      Insert No. 2

      or (b) any Event of Default occurs under the Loan Agreement of even date
herewith between Bank and Borrower ("Agreement"), as such Agreement is amended,
extended or replaced from time to time. Certain capitalized terms used in this
Rider have the definition given to them in the Agreement.

      Insert No. 3

      As used in this Note (i) "any agreement with the Bank" includes any
agreement, note or instrument with the Bank (which includes, without limitation,
the Agreement Note, the 1998 Grid Note and the Existing Bank Documents); (ii)
"accelerated" or "acceleration" means indebtedness that becomes due at maturity,
by notice after the occurrence of an Event of Default or which becomes due as a
result of a demand. All defined terms in the Agreement shall have the same
meaning herein unless otherwise defined herein.

      Automatically upon the commencement of Borrower's or any Guarantor's
bankruptcy if voluntary and upon lapse of forty-five (45) days without dismissal
if involuntary, all amounts outstanding hereunder shall become immediately due
and payable. Upon the occurrence of any other Event of Default hereunder, at the
Bank's option, all amounts hereunder shall become immediately due and payable.

BORROWER: CVC PRODUCTS, INC. a(n) |_| individual(s) |_| partnership |X|
corporation |_| ________________ organized under the laws of Delaware Address of
residence/chief executive office: ______________________________________________

BANK: MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking corporation
with its principal banking office at One M & T Plaza, Buffalo, NY 14240.

Promise to Pay. For value received, Borrower promises to pay to the order of the
Bank on demand, the principal sum of _______________________ TEN MILLION and
00/100 Dollars ($10,000,000.00) (the "Maximum Principal Amount") or the
outstanding principal amount of this Note (the "Outstanding Principal Amount"),
if less; plus interest as agreed below and reasonable (including without
limitation/reasonable attorneys fees and disbursements, whether for internal or
outside counsel) the Bank incurs in order to collect any amount due under this
Note, to negotiate or document a workout, or restructuring, or to preserve its
right or realize upon any guaranty or other security for the payment of this
Note ("Expenses").

Interest. The outstanding Principal Amount of this Note shall earn interest
calculated on the basis of 360-day year for the actual number of days of each
year (365 or 366) from and including the date the proceeds of this Note were
disbursed to, but not including, the date all amounts hereunder are paid in full
at a rate per year which shall on each day be:

|_| __________%.

|_| equal to the rate in effect on that day as the rate announced by the Bank as
its prime rate of interest.

|X| 1/4% above the rate in effect on that day as the rate announced by the Bank
as its prime rate of interest.

If no rate is specified above, interest shall accrue at the Maximum Legal Rate
(defined below) at all times prior to payment in full.

Payments; Late Charge; Default Rate. Payments shall be made in immediately
available United States funds at any banking office of the Bank. Absent
demand for payment in full, interest shall be due and payable monthly. If
payment is not received within five days of its due date, Borrower shall pay a
late charge equal to the greatest of (a) 5% of the delinquent amount, (b) the
Bank's then current late charge as announced by the Bank from time to time, or
(c) $50.00. In addition, if the Bank has not actually received any payment under
this Note within thirty days after its due date, from and after such thirtieth
day the interest rate for all amounts outstanding under this Note shall
automatically increase to 5% above the otherwise applicable rate per year.
Payments may be applied in any order in the sole discretion of the Bank but,
prior to demand, shall be applied first to past due interest, Expenses, late
charges, and principal payments, if any, which are past due, then to current
interest and Expenses and late charges, and last to remaining principal.

Maximum Legal Rate. It is the intent of the Bank and of Borrower that in no
event shall interest be payable at a rate in excess of the maximum rate
permitted by applicable law ( the "Maximum Legal Rate"). Solely to the extent
necessary to prevent interest under this Note from exceeding the Maximum Legal
Rate, any amounts that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically cancelled, and, if received by the Bank, shall be refunded to
Borrower.

Setoff. The Bank shall have the right to set off against the amounts owing under
this Note any property held in a deposit or other account with the Bank or
otherwise owing by the Bank in any capacity to Borrower or any guarantor or
endorser of this Note.

Authorized Representatives. This Note is issued by Borrower to the Bank in
connection with a certain line of credit or loan limit made available by the
Bank to Borrower (the "Credit"). The Bank may make any loan pursuant to the
Credit (the "Loan(s)") in reliance upon any oral, telephonic, written,
teletransmitted or other request (the "Request(s)") that the Bank in good faith
believes to be valid and to have been made by Borrower or on behalf of Borrower
by CHRISTINE WHITMAN or EMILIO DiCATALDO (each an "Authorized Person"). The Bank
may act on the Request of any Authorized Person until the Bank shall have
received from Borrower, and had a reasonable time to act on, written notice
revoking the authority of such Authorized Person. The Bank shall incur no
liability to Borrower or to any other person as a direct or indirect result of
making any Loan pursuant to this paragraph.

Demand Facility. The Bank may modify, restrict, suspend or terminate the Credit
at any time for any reason and without affecting Borrower's then existing
obligation under this Note. This is a demand Note and all Loans hereunder shall
become immediately due and payable upon demand by the Bank; provided, however,
that the Outstanding Principal Amount of this Note and all accrued and unpaid
interest shall automatically become immediately due and payable if Borrower or
any guarantor or endorser of this Note commences or has commenced against it any
bankruptcy or insolvency proceeding. Borrower hereby waives protest, presentment
and notice of any kind in connection with this Note.

Bank Records Conclusive. The Bank shall set forth on a schedule attached to this
Note or maintained on computer, the date and original principal amount of each
Loan and the date and amount of each payment to be applied to the Outstanding
Principal Amount of this Note. The Outstanding Principal Amount set forth on any
such schedule shall be presumptive evidence of the Outstanding Principal Amount
of this Note and of all Loans. No failure by the Bank to make, and no error by
the Bank in making, any annotation on any such schedule shall affect Borrower's
obligation to pay the principal and interest of each Loan or any other
obligation of Borrower to the Bank pursuant to this Note.

Purpose. Borrower certifies (a) that no Loan will be used to purchase margin
stock except with the Bank's express prior written consent for each such
purchase and (b) that all Loans shall be used for a business purpose, and not
for any personal, family or household purpose, unless the following box is
checked:

|_| Personal Loan. If this box is check, the initial advance must be an amount
greater than $25,000.

Authorization. Borrower, if a corporation, partnership, trust or other entity,
represents that it is duly organized and in good standing or duly constituted in
the state of its organization and is duly authorized to do business in all
jurisdictions material to the conduct of its business; that the execution,
delivery and performance of this Note have been duly authorized by all necessary
regulatory and corporate or partnership action or by its governing instrument;
that this Note has been duly executed by an authorized officer, partner or
trustee and constitutes a binding obligation enforceable against Borrower and
not in violation of any law, court order or agreement by which Borrower is
bound; and that Borrower's performance is not threatened by any pending or
threatened litigation.

<PAGE>

Miscellaneous. This Note, together with any related loan and security
agreements, contains the entire agreement between the Bank and Borrower with
respect to each Loan, and supersedes every course of dealing, other conduct,
oral agreement and representation previously made by the Bank. The Bank's rights
and remedies under applicable law and this Note are cumulative and not
exclusive. No single, partial or delayed exercise by the Bank of any right or
remedy shall preclude the subsequent exercise by the Bank at any time of any
right or remedy of the Bank without notice. No waiver or amendment of any
provision of this Note shall be effective unless made specifically in writing by
the Bank. This Note shall be governed by the laws of the State of New York,
without regard to its principles of conflict of laws. This Note is a binding
obligation enforceable against Borrower and its successors and assigns and shall
inure to the benefit of the Bank and its successors and assigns. If a court

Note, Borrower (a) consents to the personal jurisdiction of any State or federal

kept in the Bank's course of business may be admitted into evidence as an
original.

BORROWER: CVC PRDDUCTS, INC.

a(n) |_| individual(s) |_| partnership |_| corporation |_| trust |_| __________
organized under the laws of Delaware

Address of residence/chief executive office: 525 Lee Road, Rochester, New York
14606

BANK: MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking corporation
      with its principal banking office at One M&T Plaza, Buffalo, NY 14240.

Promise to Pay. For value received, Borrower promises to pay to the order of the
Bank, on the dates set forth below, the principal sum of ______________________
Dollars ($_____________) (the "Principal") plus interest as agreed below and all
reasonable fees and costs (including without limitation reasonable attorneys
fees and disbursements whether for internal or outside counsel) the Bank incurs
in order to collect any amount due under this Note, to negotiate or document a
workout, or restructuring, or to preserve its rights or realize upon any
guaranty or other security for the payment of this Note ("Expenses").

Interest. The unpaid Principal balance of this Note shall earn interest
calculated on the basis of a 360-day year for the actual number of days of each
year (365 or 366) from and including the date the proceeds of this Note were
disbursed to, but not including, the date all amounts hereunder are paid in
full, at a rate per year which shall on each day be:

|_|   ________%

|_|   equal to the rate in effect on that day as the rate announced by the Bank
      as its prime rate of interest.

|X|   .5% above the rate in effect on that day as the rate announced by the Bank
      as its prime rate of interest.

If no rate is specified above, interest shall accrue at the Maximum Legal Rate
(defined below).

Maximum Legal Rate. It is the intent of the Bank and Borrower that in no event
shall interest be payable at a rate in excess of the maximum rate permitted by
applicable law (the "Maximum Legal Rate"). If this Note is for a personal loan
of less than $2,500,000 and is secured primarily by a one- to four-family
residence, the interest rate shall not exceed 16%. Solely to the extent
necessary to prevent interest under this Note from exceeding the Maximum Legal
Rate, any amount that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically canceled, and, if received by the Bank, shall be refunded to
Borrower.

Default Rate. If an Event of Default (defined below) occurs, the interest rate
on the unpaid Principal shall immediately be automatically increased to 5% per
year above the otherwise applicable rate per year.

Repayment of Principal and Interest; Late Charge. Payments shall be made in
immediately available United States funds at any banking office of the Bank.
Interest will continue to accrue until payment is actually received. If payment
is not received within five days of its due date, Borrower shall pay a late
charge equal to the greatest of (a) $50.00, (b) 5% of the delinquent amount or
(c) the Bank's then current late charge as announced from time to time. If this
Note is secured by a one- to six-family owner-occupied residence, the late
charge shall equal 2% of the delinquent amount and shall be payable if payment
is not received within fifteen days of its due date. Payments may be applied in
any order in the sole discretion of the Bank but, prior to default, shall be
applied first to past due interest, Expenses, late charges and principal, then
to current interest, Expenses, late charges and principal, and last to remaining
principal.

The Maturity Date of this Note is __________________,199/20__.

|_|   Borrower shall pay the entire Principal on the Maturity Date. In addition,
      until the outstanding Principal is paid in full, payments of all accrued
      and unpaid interest in amounts which will vary will become due and payable
      on the _______ day of each:

      |_| month  |_| quarter  |_| year commencing on ____________, 19__.

|X|   Borrower shall pay the Principal in _______ consecutive |X| monthly |_|
      quarterly |_| annual payments due on the first day of each month
      commencing on _____________,19__. In addition, until the outstanding
      Principal is paid in full, payments of all accrued and unpaid interest in
      amounts which will vary will become due and payable as of the 1st day of
      each: |X| month |_| quarter |_| year commencing on ___________________,
      19__. Each Principal payment will equal $______________ except that the
      last Principal payment will also include all other amounts due hereunder.

|_|   Borrower shall pay _______ consecutive level |_| monthly |_| quarterly
      |_| annual installments consisting of both Principal and interest,
      amortized over a period of _______ years, commencing on _________________,
      19__. Each payment will equal $ except that the last payment will equal
      all remaining amounts due under this Note.

      IF A PAYMENT IS RECEIVED AFTER THE DUE DATE, MORE INTEREST WILL BE DUE
      THAN PLANNED AND LESS MONEY APPLIED TO PRINCIPAL. REPEATED LATE PAYMENTS
      WILL CAUSE AN UNEXPECTED PRINCIPAL BALANCE TO REMAIN UNPAID AT THE END OF
      THE TERM.

Prepayment Premium. During the term of this Note, Borrower shall have the option
of paying the Principal to the Bank in advance of the Maturity Date, in whole or
in part, at any time and from time to time upon written notice received by the
Bank at least three (3) business days prior to making such payment; provided,
however, that together with such prepayment, Borrower shall pay to the Bank a
premium equal to the product of (a) one percent of the Principal prepaid
multiplied by (b) the number of years remaining in the Term, rounded up to the
next whole year. For example, if the Term is five years, the premium shall equal
5% of the Principal Sum prepaid before the first anniversary of this Note, 4% of
the Principal Sum prepaid before the second anniversary of this Note, etc. Upon
making any prepayment of the Principal Sum in whole, Borrower shall pay to the
Bank all interest and Expenses owing pursuant to this Note and remaining unpaid.
Each partial prepayment of Principal shall be applied in inverse order of
maturity to the principal included in the installments provided for in the
paragraph of the Note captioned "Repayment of Principal and Interest."

In the event the Maturity Date of this Note is accelerated following an Event of
Default by Borrower, any tender of payment of the amount necessary to satisfy
the entire indebtedness made after such Event of Default shall be expressly
deemed a voluntary prepayment. In such a case, to the extent permitted by law,
the Bank shall be entitled to the amount necessary to satisfy the entire
indebtedness, plus the appropriate prepayment premium calculated in accordance
with the preceding paragraph.

      1. Guaranty. (a) Guarantor guarantees to the Bank the full and immediate
payment and performance of all of Borrower's obligations to the Bank from time
to time of every kind and nature, now existing and hereafter incurred, direct
and contingent, liquidated and unliquidated, secured and unsecured, matured and
unmatured, including all accrued and unpaid interest and all Expenses (defined
below) even if such obligations were originally contracted with another lender
or jointly with other borrowers, even if not evidenced by a writing, and even if
periodically extinguished and reincurred (the "Obligations"). Guarantor will pay
or perform its obligations under this Guaranty upon demand. This is a guaranty
of payment, not collection.

      (b) Guarantor acknowledges the receipt of valuable consideration for this
Guaranty and acknowledges that the Bank is relying on this Guaranty in making a
financial accommodation to Borrower, whether a commitment to lend, extension,
modification or replacement of, or forbearance with respect to, any Obligation,
cancellation of another guaranty, purchase of Borrower's assets, or other
valuable consideration. Any prior extension of credit by Bank to Borrower shall
also constitute consideration for this Guaranty.

      2. Continuing, Unconditional and Unlimited Guaranty. This Guaranty is
irrevocable, continuing, unconditional and general without any limitation.

      3. Guarantor's Waivers. (a) Guarantor's obligations shall not be released,
impaired or affected in any way by (i) Borrower's bankruptcy, reorganization or
insolvency under any law or that of any other party, or by any action of a
trustee in any such proceeding; (ii) failure of any other party to perform its
obligations to the Bank; or (iii) any other circumstance that might constitute a
legal or equitable defense to Guarantor's or Borrower's obligations under this
Guaranty, including without limitation: (A) any new agreements or obligations of
Borrower with or to the Bank, amendments, changes in rate of interest,
extensions of time for payments, modifications, renewals or the existence of or
waivers of default as to any existing or future agreements of Borrower or any
other party with the Bank; (B) any adjustment, compromise or release of any
Obligations of Borrower, by the Bank or any other party; the existence or
nonexistence or order of any filings, exchanges, releases, impairment or sale
of, or failure to perfect a security interest in, any security for the
Obligations, or the order in which payments and proceeds of collateral are
applied; or acceptance by the Bank of any writing intended by any other party to
create an accord and satisfaction with respect to any of the Obligations; (C)
any fictitiousness, incorrectness, invalidity or unenforceability, for any
reason, of any instrument or other agreement, or act of commission or omission
by the Bank or Borrower; (D) any composition, extension, moratoria or other
statutory relief granted to Borrower; or (E) any interruption in the business
relations between the Bank and Borrower, or any dissolution or change in form of
organization, name or ownership of Borrower or Guarantor.

      (b) Waivers of Notice, etc. The Guarantor waives acceptance, assent and
all rights of notice or demand including without limitation (i) notice of
acceptance of this Guaranty, of Borrower's default or nonpayment of any
Obligation, and of changes in Borrower's financial condition; (ii) presentment,
protest, notice of protest and demand for payment; and (iii) any other notice,
demand or condition to which Guarantor might otherwise be entitled prior to the
Banks reliance on or enforcement of this Guaranty.

      (c) Waiver of Subrogation. Notwithstanding any other provision in this
Guaranty, Guarantor irrevocably waives, without notice, any right it may have at
law or in equity (including without limitation any law subrogating Guarantor to
the rights of the Bank) to seek contribution, indemnification or any other form
of reimbursement from Borrower or any other obligor or guarantor of the
Obligations for any disbursement made under this Guaranty or otherwise.

      4. Termination; Reinstatement. This Guaranty can be terminated (a) only
with respect to Obligations not yet incurred, and (b) only by actual receipt by
the Bank officer named above of written notice of Guarantor's intent to
terminate (or Guarantor's dissolution) plus (c) the lapse of a reasonable time
for Bank to act on such notice. This Guaranty cannot be terminated with respect
to any Obligations committed or contracted for or outstanding at the time the
Bank acts on such notice, or any prior or subsequent modifications, renewals,
extensions or replacements of or interest on such Obligations, or related
expenses. If any payment the Bank has received prior to termination subsequently
is declared fraudulent or preferential or for any other reason required to be
surrendered, Guarantor's obligations under this Guaranty and any related
security agreements shall be reinstated and remain in effect until the Bank has
actually received payment in full of the Obligations.

      5. Expenses. Guarantor agrees to reimburse the Bank on demand for all the
Banks expenses, costs, damages and losses of any kind or nature, including
without limitation actual attorneys' fees and disbursements whether for internal
or external counsel incurred by the Bank in attempting to enforce this Guaranty,
collect or restructure any of the Obligations, realize on any collateral, or for
any other purpose related to the Obligations including but not limited to costs
of workout, negotiations, redocumentation or bankruptcy or other legal
proceedings or appeal (collectively "Expenses"). Expenses will accrue interest
at the highest legal rate until payment is actually received by the Bank.

      6. Financial and Other Information. Guarantor shall provide Bank with same
financial statements and other information Borrower is required to provide Bank
under a Loan Agreement entered into by Bank and Borrower on or about the date
this Guaranty was executed ("Loan Agreement"), as the Loan Agreement is
extended, amended and replaced. Guarantor represents that its assets are not
subject to any liens, encumbrances or contingent liabilities except as fully
disclosed to the Bank in such statements.

      7. Security; Right of Setoff. As further security for payment of the
Obligations, Expenses and any other obligations of Guarantor to the Bank,

above). No single, partial or delayed exercise by the Bank of any right or
remedy shall preclude exercise by the Bank at any time at its sole option of the

BANK: Manufacturers and Traders Trust Company, One M&T Plaza, Buffalo, New York
14240    Attention: Office of General Counsel

      1. Guaranty. (a) Guarantor guarantees to the Bank the full and immediate
payment and performance of all of Borrower's obligations to the Bank from time
to time of every kind and nature, now existing and hereafter incurred, direct
and contingent, liquidated and unliquidated, secured and unsecured, matured and
unmatured, including all accrued and unpaid interest and all Expenses (defined
below) even if such obligations were originally contracted with another lender
or jointly with other borrowers, even if not evidenced by a writing, and even if
periodically extinguished and reincurred (the "Obligations"). Guarantor will pay
or perform its obligations under this Guaranty upon demand. This is a guaranty
of payment, not collection.

      (b) Guarantor acknowledges the receipt of valuable consideration for this
Guaranty and acknowledges that the Bank is relying on this Guaranty in making a
financial accommodation to Borrower, whether a commitment to lend, extension,
modification or replacement of, or forbearance with respect to, any Obligation,
cancellation of another guaranty, purchase of Borrower's assets, or other
valuable consideration. Any prior extension of credit by Bank to Guarantor shall
also constitute consideration for this Guaranty.

      2. Continuing, Unconditional and Unlimited Guaranty. This Guaranty is
irrevocable, continuing, unconditional and general without any limitation.

      3. Guarantor's Waivers. (a) Guarantor's obligations shall not be released,
impaired or affected in any way by (i) Borrower's bankruptcy, reorganization or
insolvency under any law or that of any other party, or by any action of a
trustee in any such proceeding; (ii) failure of any other party to perform its
obligations to the Bank; or (iii) any other circumstance that might constitute a
legal or equitable defense to Guarantor's or Borrower's obligations under this
Guaranty, including without limitation: (A) any new agreements or obligations of
Borrower with or to the Bank, amendments, changes in rate of interest,
extensions of time for payments, modifications, renewals or the existence of or
waivers of default as to any existing or future agreements of Borrower or any
other party with the Bank; (B) any adjustment, compromise or release of any
Obligations of Borrower, by the Bank or any other party; the existence or
nonexistence or order of any filings, exchanges, releases, impairment or sale
of, or failure to perfect a security interest in, any security for the
Obligations, or the order in which payments and proceeds of collateral are
applied; or acceptance by the Bank of any writing intended by any other party to
create an accord and satisfaction with respect to any of the Obligations; (C)
any fictitiousness, incorrectness, invalidity or unenforceability, for any
reason, of any instrument or other agreement, or act of commission or omission
by the Bank or Borrower; (D) any composition, extension, moratoria or other
statutory relief granted to Borrower; or (E) any interruption in the business
relations between the Bank and Borrower, or any dissolution or change in form of
organization, name or ownership of Borrower or Guarantor.

      (b) Waivers of Notice, etc. The Guarantor waives acceptance, assent and
all rights of notice or demand including without limitation (i) notice of
acceptance of this Guaranty, of Borrower's default or nonpayment of any
Obligation, and of changes in Borrower's financial condition; (ii) presentment,
protest, notice of protest and demand for payment; and (iii) any other notice,
demand or condition to which Guarantor might otherwise be entitled prior to the
Banks reliance on or enforcement of this Guaranty.

      (c) Waiver of Subrogation. Notwithstanding any other provision in this
Guaranty, Guarantor irrevocably waives, without notice, any right it may have at
law or in equity (including without limitation any law subrogating Guarantor to
the rights of the Bank) to seek contribution, indemnification or any other form
of reimbursement from Borrower or any other obligor or guarantor of the
Obligations for any disbursement made under this Guaranty or otherwise.

      4. Termination; Reinstatement. This Guaranty can be terminated (a) only
with respect to Obligations not yet incurred, and (b) only by actual receipt by
the Bank officer named above of written notice of Guarantor's intent to
terminate (or Guarantor's dissolution) plus (c) the lapse of a reasonable time
for Bank to act on such notice. This Guaranty cannot be terminated with respect
to any Obligations committed or contracted for or outstanding at the time the
Bank acts on such notice, or any prior or subsequent modifications, renewals,
extensions or replacements of or interest on such Obligations, or related
expenses. If any payment the Bank has received prior to termination subsequently
is declared fraudulent or preferential or for any other reason required to be
surrendered, Guarantor's obligations under this Guaranty and any related
security agreements shall be reinstated and remain in effect until the Bank has
actually received payment in full of the Obligations.

      5. Expenses. Guarantor agrees to reimburse the Bank on demand for all the
Banks expenses, costs, damages and losses of any kind or nature, including
without limitation actual attorneys' fees and disbursements whether for internal
or external counsel incurred by the Bank in attempting to enforce this Guaranty,
collect or restructure any of the Obligations, realize on any collateral, or for
any other purpose related to the Obligations including but not limited to costs
of workout, negotiations, redocumentation or bankruptcy or other legal
proceedings or appeal (collectively "Expenses"). Expenses will accrue interest
at the highest legal rate until payment is actually received by the Bank.

      6. Financial and Other Information. Guarantor shall provide Bank with such
financial and other information as Guarantor is required to provide Bank under a
Loan Agreement entered into by Guarantor and Bank on or about the date this
Guaranty was executed ("Loan Agreement"), as the Loan Agreement is extended,
amended and replaced. Guarantor represents that its assets are not subject to
any liens, encumbrances or contingent liabilities except as fully disclosed to
the Bank in such statements.

      7. Security; Right of Setoff. As further security for payment of the
Obligations, Expenses and any other obligations of Guarantor to the Bank,
Guarantor hereby grants to the Bank a security interest in all money, securities
and other property of Guarantor in the actual or constructive possession or
control of the Bank including without limitation all deposits and other accounts
owing at any time by the Bank in any capacity to Guarantor in any capacity
(collectively "Property"). The Bank shall have the right to set off Guarantor's
Property against any of Guarantor's obligations to the Bank and shall have all
of the rights and remedies of a secured party under the Uniform Commercial Code
in addition to those under this Guaranty and other agreements and applicable
law.
<PAGE>

      8. No Transfer of Assets. Guarantor shall not transfer, reinvest or
otherwise dispose of its assets in a manner or to an extent that would or might
impair Guarantor's ability to perform its obligations under this Guaranty.

between Guarantor and the Bank with respect to the Guaranty. This Guaranty may
be assigned by the Bank, shall inure to the benefit of the Bank and its
successors and assigns, and shall be binding upon Guarantor and its successors
and assigns. All rights and remedies of the Bank are cumulative and no such
right or remedy shall be exclusive of any other right or remedy. This Guaranty
does not supersede any other guaranty or security granted to the Bank by
Guarantor or others (except as to Guarantor's Waiver of Subrogation rights
above). No single, partial or delayed exercise by the Bank of any right or
remedy shall preclude exercise by the Bank at any time at its sole option of the
same or any other right or remedy of the Bank without notice. No course of
dealing or other conduct, no oral agreement or representation made by the Bank
or usage of trade shall operate as a waiver of any right or remedy of the Bank.
No waiver or amendment of any right or remedy of the Bank or release by the Bank
shall be effective unless made specifically in writing by the Bank. This
Guaranty shall be governed by the laws of the State of New York, without regard
to its principles of conflict of laws. Each provision of this Guaranty shall be
interpreted as consistent with existing law and shall be deemed amended to the
extent necessary to comply with any conflicting law. If any provision is
nevertheless held invalid the other provisions shall remain in effect. Captions
are solely for convenience and are not part of the substance of this Guaranty.

<PAGE>

      6.2 Assignors' Duties, Etc.

            The Assignors shall have the duty, through patent counsel acceptable
to the Bank, to prosecute diligently any patent applications of the Patents
pending as of the date of this Patent Agreement or thereafter, to make
application for unpatented but reasonably patentable inventions and to preserve
and maintain all rights in the Patents, including without limitation the payment
when due of all maintenance fees and other fees, taxes and other expenses which
shall be incurred or which shall accrue with respect to any of the Patents. Any
expenses incurred in connection with such applications and actions shall be
borne by the Assignors. The Assignors shall not abandon any filed patent
application, or any pending patent application or patent, without the consent of
the Bank, which consent shall not be unreasonably withheld. The Bank hereby
appoints the Assignors as its agent for all matters referred to in the foregoing
provisions of this Section 6 and agrees to execute any documents necessary to
confirm such appointment. Upon the occurrence and during the continuance of an
Event of Default, the Bank may terminate such agency by providing written notice

            The Assignors shall have the right, with the consent of the Bank,
which shall not be unreasonably withheld, to bring suit or other action in the
Assignors' own name(s) to enforce the Patents and the Patent Rights. The Bank
shall be required to join in such suit or action as may be necessary to assure
the Assignors' ability to bring and maintain any such suit or action in any
proper forum so long as the Bank is completely satisfied that such joinder will
not subject the Bank to any risk of liability. The Assignors shall promptly,
upon demand, reimburse and indemnify the Bank for all damages, costs and
expenses, including legal fees, incurred by the Bank pursuant to this Section 6.

      6.4 Protection of Patents, Etc.

            In general, the Assignors shall take any and all such actions
(including but not limited to institution and maintenance of suits, proceedings
or actions) as may be necessary or appropriate to properly maintain, protect,
preserve, care for and enforce the Patent Collateral. The Assignors shall not
take or fail to take any action, nor permit any action to be taken or not taken
by others under their control, which would affect the validity, grant or
enforcement of any of the Patent Collateral.

      6.5 Notification by Assignors.

            Promptly upon obtaining knowledge thereof, the Assignors will notify
the Bank in writing of the institution of, or any final adverse determination
in, any proceeding in the PTO or any similar office or agency of the United
States or any foreign country, or any court, regarding the validity of any of
the Patents or the Assignors' rights, title or interests in and to any of the
Patent Collateral, and of any event which does or


                                      -6-
<PAGE>

reasonably could materially adversely affect the value of any of the Patent
Collateral, the ability of the Assignors or the Bank to dispose of any of the
Patent Collateral or the rights and remedies of the Bank in relation thereto
(including, but not limited to, the levy of any legal process against any of the
Patent Collateral).

7. LICENSE BACK TO ASSIGNORS.

      Unless and until there shall have occurred and be continuing an Event of
Default and the Bank has notified the Assignors that the license granted
hereunder is terminated, the Bank hereby grants to the Assignors the sole and
exclusive, nontransferable, royalty-free, worldwide right and license under the
Patents to make, have made for them, use, sell and otherwise practice the
inventions disclosed and claimed in the Patents for the Assignors' own benefit
and account and for none other; provided, however, that the foregoing right and
license shall be no greater in scope than, and limited by, the rights assigned
to the Bank by the Assignors hereby. The Assignors agree not to sell, assign,
transfer, encumber or sublicense their interest in the license granted to the
Assignors in this Section 7, without the prior written consent of the Bank. Any
such sublicenses granted on or after the date hereof shall be terminable by the
Bank upon termination of the Assignors' license hereunder.

8. REMEDIES.

      If any Event of Default shall have occurred and be continuing, then upon
notice by the Bank to the Assignors: (i) the Assignors' license with respect to
the Patents as set forth in Section 7 shall terminate; (ii) the Assignors shall
immediately cease and desist from the practice, manufacture, use and sale of the
inventions claimed, disclosed or covered by the Patents; and (iii) the Bank
shall have, in addition to all other rights and remedies given it by this Patent
Agreement, the Loan Agreement, the Security Agreements, and all other
agreements, instruments and documents executed by Borrower and/or Parent in
favor of Bank at any time, those allowed by law and the rights and remedies of a
secured party under the Uniform Commercial Code as enacted in the State of New
York and, without limiting the generality of the foregoing, the Bank may
immediately, without demand of performance and without other notice (except as
set forth next below) or demand whatsoever to the Assignors, all of which are
hereby expressly waived, and without advertisement, sell or license at public or
private sale or otherwise realize upon the whole or from time to time any part
of the Patent Collateral, or any interest which the Assignors may have therein,
and after deducting from the proceeds of sale or other disposition of the Patent
Collateral all reasonable expenses (including all reasonable expenses for
broker's fees and legal services), shall apply the residue of such proceeds
toward the payment of the Obligations as set forth in the Security Agreements.
Notice of any sale, license or other disposition of any of the Patent Collateral
shall be given to the Assignors at least five (5) days before the time that any
intended public sale or other disposition of such Patent Collateral is to be
made or after which any private sale or other disposition of such Patent
Collateral may be made, which the Assignors hereby agrees shall be reasonable
notice of such public or private sale or


                                      -7-
<PAGE>

other disposition. At any such sale or other disposition, the Bank may, to the
extent permitted under applicable law, purchase or license the whole or any part
of the Patent Collateral or interests therein sold, licensed or otherwise
disposed of.

9. COLLATERAL PROTECTION.

      If the Assignors shall fail to do any act that they have covenanted to do
hereunder, or if any representation or warranty of the Assignors shall be
breached, the Bank, in their own name or that of the Assignors (in the sole
discretion of the Bank), may (but shall not be obligated to) do such act or
remedy such breach (or cause such act to be done or such breach to be remedied),
and the Assignors agree promptly to reimburse the Bank for any cost or expense
incurred by the Bank in so doing.

10. POWER OF ATTORNEY.

      If any Event of Default shall have occurred and be continuing, the
Assignors do hereby make, constitute and appoint the Bank (and any officer or
agent of the Bank as the Bank may select in its exclusive discretion) as the
Assignors' true and lawful attorney-in-fact, with the power to endorse the
Assignors' name on all applications, documents, papers and instruments necessary
for the Bank to use any of the Patent Collateral, to practice, make, use or sell
the inventions disclosed or claimed in any of the Patent Collateral, to grant or
issue any exclusive or nonexclusive license of any of the Patent Collateral to
any third person, or necessary for the Bank to assign, pledge, convey or
otherwise transfer title in or dispose of the Patent Collateral or any part
thereof or interest therein to any third person, and, in general, to execute and
deliver any instruments or documents and do all other acts which the Assignors
are obligated to execute and do hereunder. The Assignors hereby ratify all that
such attorney shall lawfully do or cause to be done by virtue hereof, and
releases the Bank from any claims, liabilities, causes of action or demands
arising out of or in connection with any action taken or omitted to be taken by
the Bank under this power of attorney (except for the Bank's gross negligence or
willful misconduct). This power of attorney shall be irrevocable for the
duration of this Patent Agreement.

11. FURTHER ASSURANCES.

      The Assignors shall, at any time and from time to time, and at their
expense, make, execute, acknowledge and deliver, and file and record as
necessary or appropriate with governmental or regulatory authorities, agencies

other and further acts and things (including, without limitation, obtaining
consents of third parties), as the Bank may request or as may be necessary or
appropriate in order to implement and effect fully the intentions, purposes and
provisions of this Patent Agreement, or to assure and confirm to the Bank the
grant, perfection and priority of the Bank's security interest in any of the
Patent Collateral.

12. TERMINATION.

      At such time as all of the Obligations have been finally paid and
satisfied in full and neither of the Assignors have any right to request
advances from Bank under a line of credit, this Patent Agreement shall terminate
and the Bank shall, upon the written request and at the expense of the
Assignors, execute and deliver to the Assignors all deeds, assignments and other
instruments as may be necessary or proper to reassign and reconvey to and
re-vest in the Assignors the entire right, title and interest to the Patent
Collateral previously granted, assigned, transferred and conveyed to the Bank by
the Assignors pursuant to this Patent Agreement, as fully as if this Patent
Agreement had not been made, subject to any disposition of all or any part
thereof which may have been made by the Bank pursuant hereto or the Security
Agreements.

13. COURSE OF DEALING.

      No course of dealing among the Assignors and the Bank, nor any failure to
exercise, nor any delay in exercising, on the part of the Bank, any right, power
or privilege hereunder or under the Security Agreements shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or thereunder preclude any other or further exercise thereof
or the exercise of any other right, power or privilege.

14. EXPENSES.

      CVC has no prior opinions or similar documents relating to the scope or
validity of its trademarks. No maintenance fees are presently due for CVC's
existing CONNEXION(TM) trademark registration. In addition, there are no
documents relating to litigation or licenses involving CVC's trademarks, related
foreign filings, and product-line information related to the trademarks.

      3. CVC's Foreign Trademark Assets. To date, CVC holds no foreign trademark
registrations. Nor does CVC, as of the date of this Intellectual Property Audit
Report, have pending any foreign trademark applications. To the extent that CVC
uses a particular mark for a product it sells in a foreign market, those marks
appearing in Table 5, above, represent the only marks CVC uses outside the
United States.

            There are no prior opinions or documents relating to the scope or
validity of CVC's trademarks outside the United States. Nor are there any
foreign patent and trademark office actions or maintenance fee dates due at this
time. No documents relating to litigation or licenses involving CVC's
trademarks, related foreign filings, and product-line information related to the
use of trademarks outside the United States were discovered in this Intellectual
Property Audit.

E. Copyright Assets and Related Intellectual Property Assets

      1. Overview. The Copyright Act establishes copyright protection "in
original works of authorship fixed in any tangible medium of expression." Each
word in this phrase must be satisfied in order to create a copyright. The work
must be original, meaning that it was created by the author--that is, it
"originated" with the author, not someone else but it need not be highly unique
or creative, which is required for some other forms of intellectual property
protection, such as patents. A work must be fixed in some tangible way in order
to create a copyright. Authors cannot simply come up with brilliant ideas for
books or songs and carry them

      RE:   CVC Products, Inc.

Gentlemen:

      We have acted as special counsel to CVC Products, Inc., a Delaware
corporation ("Borrower"), in connection with certain credit facilities to be
made by Manufacturers and Traders Trust Company ("Bank") to Borrower pursuant to
a certain Loan Agreement of even date herewith ("Closing Date") between Bank and
Borrower, dated as of March 31, 1998 (the "Loan Agreement"). Furthermore, we
have acted as special counsel to CVC, Inc., a Delaware corporation ("Parent")
and have advised it in connection with certain matters pertaining to the Loan
Agreement. Unless otherwise noted, the agreements referred to in (i) through
(ix) below were executed on the Closing Date, as of March 31, 1998. We are
giving the opinions set forth below at the request of Borrower and Parent.

      In our capacity as special counsel to Borrower and Parent, we have
reviewed the Loan Agreement and the following documents, as executed:

      (i)   $8,000,000 Term Note, dated as of March 31, 1998, executed by
            Borrower in favor of Bank ("Term Note");

      (ii)  $10,000,000 Grid Note, dated as of March 31, 1998, executed by
            Borrower in favor of Bank ("Grid Note");

      (iii) Trademark Collateral Security and Pledge Agreement executed by
            Borrower, Parent and Bank dated as of March 31, 1998 ("Trademark
            Agreement");

      (iv)  Patent Collateral Assignment and Security Agreement executed by
            Borrower, Parent and Bank dated as of March 31, 1998 ("Patent
            Agreement");

      (v)   Amended and Restated Continuing Guaranty, dated as of March 31,
            1998, executed by Borrower in favor of Bank ("Borrower Guaranty");

      (vi)  Amended and Restated General Security Agreement, dated as of March
            31, 1998, executed by Borrower in favor of Bank ("Borrower GSA");

      (vii) Amended and Restated Continuing Guaranty, dated as of March 31.
            1998, executed by Parent in favor of Bank ("Parent Guaranty");

     (viii) Amended and Restated General Security Agreement, dated as of March
            31. 1998, executed by Parent in favor of Bank ("Parent GSA"); and

      (ix)  Landlord/Mortgagee Waiver, dated as of March 31, 1998. executed by
            Parent in favor of Bank ("Landlord Waiver").

      The Term Note, Grid Note, Borrower Guaranty and Borrower GSA are
hereinafter collectively referred to as the "Borrower Loan Documents." The
Parent Guaranty, Parent GSA and Landlord Waiver are hereinafter collectively
referred to as the "Guarantor Loan Documents." The Borrower Loan Documents, the
Guarantor Loan Documents, the Trademark Agreement and the Patent Agreement are
referred to collectively as the "Loan Documents."

      We have also examined the Certificate of Incorporation and By-Laws of
Borrower and Parent and copies, certified or otherwise identified to our
satisfaction, of such other documents, records and certificates of public
officials and of the Borrower and Parent, made such inquiries of officers of
Borrower and Parent and considered such questions of law as we deemed necessary
for the purpose of rendering the opinions set forth herein.

      As to questions of fact material to the opinions set forth herein, we
have, when relevant facts were not independently established, made inquiries as
to such questions of fact of officers of Borrower and Parent and relied upon
certificates of, and information received from, officers of Borrower and Parent,
in each case, copies of which are annexed hereto as exhibits. As to any opinions
expressed herein "to our knowledge," such knowledge is based solely upon
certificates of, and information received from, officers of Borrower and Parent
and any actual knowledge we may have from any other source. We have not
independently investigated or verified the facts represented in such
certificates or information and do not opine as to the accuracy of any such
facts.

      In rendering the opinions set forth below, we have assumed that:

      A. Authority of Bank. Bank has all requisite power and authority to (i)
consummate the transactions described in the Loan Documents, (ii) execute and
deliver the Loan Documents to which it is a party and (iii) perform its
obligations thereunder.

      B. Execution by Bank. Bank has duly and validly authorized, executed and
delivered the Loan Documents to which it is a party.

      C. Modifications. There are no oral or written modifications of or
amendments to the Loan Documents.

under the Guarantor Loan Documents and (c) grant the security interests provided

under, the Guarantor Loan Documents, the Trademark Agreement and the Patent
Agreement have been duly authorized by all necessary corporate action on the
part of Parent, and the Guarantor Loan Documents, the Trademark Agreement and
the Patent Agreement have been duly executed and delivered by Parent.

      12. To our knowledge, there is no action, suit or proceeding pending, or
overtly threatened by written communication, against Borrower or expressly
affecting its assets wherein an unfavorable decision, ruling or finding, in any
case or in the aggregate, would materially adversely affect the Borrower's
financial condition or any of its assets, or the validity or enforceability of
any of the Borrower Loan Documents, the Trademark Agreement or the Patent
Agreement.

      13. To our knowledge, there is no action, suit or proceeding pending, or
overtly threatened by written communication, against Parent or expressly
effecting its assets wherein an unfavorable decision, ruling or finding, in any
case or in the aggregate, would materially adversely affect Parent's financial
condition or any of its assets, or the validity or enforceability of any of the
Guarantor Loan Documents, the Trademark Agreement or the Patent Agreement.

      The opinions expressed above are subject to the following qualifications:

            (a) the enforceability of the Loan Documents may be limited by the
      time of recording of the Patent Agreement and the Trademark Agreement, and
      by applicable bankruptcy, reorganization, insolvency, moratorium,
      fraudulent conveyance, and other similar laws now or hereafter in effect
      relating to or affecting creditor's rights generally;

            (b) the enforcement of rights and remedies under the Loan Documents
      may be limited by (i) general principles of equity, regardless of whether
      such enforcement is considered in a proceeding in equity or at law, or
      (ii) the policies underlying applicable law;

            (c) we express no opinion as to the enforceability of the self-help,
      non-judicial remedies provided to Bank in the Loan Documents (including,
      inter alia, remedies purportedly based upon the appointment of Bank as
      attorney-in-fact of Borrower);

            (d) certain provisions in the Loan Documents may be rendered
      unenforceable or limited by applicable laws and judicial decisions; but
      such laws and judicial decisions do not render the Loan Documents legally
      inadequate remedies for the realization of the principal benefits and
      security intended to be provided thereby;

            (e) enforceability of the Loan Documents may be limited by any
      unconscionable or inequitable conduct on Bank's part, defenses arising
      from Bank's failure to act in accordance with the terms and conditions of
      the Loan Documents and defenses arising as a result of Bank's failure to
      act in good faith and in a commercially reasonable manner;

            (f) we express no opinion as to the validity or enforceability of
      any waiver of service of judicial process, or any provisions of any of the
      Loan Documents which might be construed as a waiver of counterclaims or
      defenses;

            (g) we express no opinion as to (i) compliance with or the effect of
      any applicable health, safety, zoning, land use, environmental, tax,
      anti-trust or securities law, rule, regulation or ordinance; (ii) the
      existence or state of title of any real or personal property which may be
      the subject of any of the Loan Documents; (iii) the priority of any liens
      or security interest created or purported to be created by any of the Loan
      Documents; (iv) the perfection of any security interest in the Collateral;
      or (v) the Banl&s right to collect any payment due to the extent that such
      payment constitutes a penalty, forfeiture or late payment charge;

            (h) we express no opinion as to the enforceability of the provisions
      of the Grid Note and Loan Agreement requiring payment on demand;

            (i) we express no opinion as to the enforceability of Section 6.2 of
      the Trademark Agreement or Section 5.2 of the Patent Agreement;

            (j) we express no opinion as to the enforceability of the provisions
      of Section 8 of the Trademark Agreement with respect to the sale of any
      Trademark apart from its Associated Goodwill and the business symbolized
      by such Trademark; and

            (k) we express no opinion as to the enforceability of the Trademark
      Agreement to the extent that it purports to independently assign the
      Pledged Trademarks as opposed to being an assignment in furtherance of a
      security interest granted in the Pledged Trademarks.

      This opinion is specifically limited to the present General Corporation
Law of the State of Delaware and the present internal laws of the State of New
York and federal law of the United States, and no opinion is expressed as to the
effect that the law of any other jurisdiction might have upon the subject matter
of the opinions expressed herein under the conflicts of law principles or
otherwise.

      This opinion is being rendered solely for the benefit of Bank in
connection with the transactions contemplated by the Loan Documents. No other
person may rely on this opinion for any purpose without the express written
consent of the undersigned. This opinion is limited to the matters set forth
herein, no opinion may be inferred or implied beyond the matters expressly

                                    TERM NOTE

Rochester, New York as of March 31, 1998                           $8,000,000.00

BORROWER: CVC PRODUCTS, INC.

a(n) |_| individual(s) |_| partnership |X| corporation |_| trust |_| __________
organized under the laws of Delaware

Address of residence/chief executive office: 525 Lee Road, Rochester, New York
14606

BANK: MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking corporation
      with its principal banking office at One M&T Plaza, Buffalo, NY 14240.

Promise to Pay. For value received, Borrower promises to pay to the order of the
Bank, on the dates set forth below, the principal sum of EIGHT MILLION and
00/100 Dollars ($8,000,000.00) (the "Principal") plus interest as agreed below
and all reasonable fees and costs (including without limitation reasonable
attorneys fees and disbursements whether for internal or outside counsel) the
Bank incurs in order to collect any amount due under this Note, to negotiate or
document a workout, or restructuring, or to preserve its rights or realize upon
any guaranty or other security for the payment of this Note ("Expenses").

Interest. The unpaid Principal balance of this Note shall earn interest
calculated on the basis of a 360-day year for the actual number of days of each
year (365 or 366) from and including the date the proceeds of this Note were
disbursed to, but not including, the date all amounts hereunder are paid in
full, at a rate per year which shall on each day be:

|X|   8.39%

|_|   equal to the rate in effect on that day as the rate announced by the Bank
      as its prime rate of interest.

|_|   _______% above the rate in effect on that day as the rate announced by the
      Bank as its prime rate of interest.

If no rate is specified above, interest shall accrue at the Maximum Legal Rate
(defined below).

Maximum Legal Rate. It is the intent of the Bank and Borrower that in no event
shall interest be payable at a rate in excess of the maximum rate permitted by
applicable law (the "Maximum Legal Rate"). If this Note is for a personal loan
of less than $2,500,000 and is secured primarily by a one- to four-family
residence, the interest rate shall not exceed 16%. Solely to the extent
necessary to prevent interest under this Note from exceeding the Maximum Legal
Rate, any amount that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically canceled, and, if received by the Bank, shall be refunded to
Borrower.

Default Rate. If an Event of Default (defined below) occurs, the interest rate
on the unpaid Principal shall immediately be automatically increased to 5% per
year above the otherwise applicable rate per year.

Repayment of Principal and Interest; Late Charge. Payments shall be made in
immediately available United States funds at any banking office of the Bank.
Interest will continue to accrue until payment is actually received. If payment
is not received within five days of its due date, Borrower shall pay a late
charge equal to the greatest of (a) $50.00, (b) 5% of the delinquent amount or
(c) the Bank's then current late charge as announced from time to time. If this
Note is secured by a one- to six-family owner-occupied residence, the late
charge shall equal 2% of the delinquent amount and shall be payable if payment
is not received within fifteen days of its due date. Payments may be applied in
any order in the sole discretion of the Bank but, prior to default, shall be
applied first to past due interest, Expenses, late charges and principal, then
to current interest, Expenses, late charges and principal, and last to remaining
principal.

The Maturity Date of this Note is April 1, 2005.

|_|   Borrower shall pay the entire Principal on the Maturity Date. In addition,
      until the outstanding Principal is paid in full, payments of all accrued
      and unpaid interest in amounts which will vary will become due and payable
      on the _______ day of each:

      |_| month  |_| quarter  |_| year commencing on ____________, 19__.

|X|   Borrower shall pay 84 consecutive level |X| monthly |_| quarterly |_|
      annual installments consisting of both Principal and interest, amortized
      over a period of 7 years, commencing on May 1, 1998 and also due on the
      first day of each month thereafter. Each payment will equal $ 126,249.81
      except that the last payment will equal all remaining amounts due under
      this Note.

      IF A PAYMENT IS RECEIVED AFTER THE DUE DATE, MORE INTEREST WILL BE DUE
      THAN PLANNED AND LESS MONEY APPLIED TO PRINCIPAL. REPEATED LATE PAYMENTS
      WILL CAUSE AN UNEXPECTED PRINCIPAL BALANCE TO REMAIN UNPAID AT THE END OF
      THE TERM.

CLB-102 (12/94) 360-Day Base

<PAGE>

Prepayment Premium. During the term of this Note, Borrower shall have the option
of paying the Principal to the Bank in advance of the Maturity Date, in whole or
in part, at any time and from time to time. Upon making any prepayment of the
Principal Sum in whole, Borrower shall pay to the Bank all interest and Expenses
owing pursuant to this Note and remaining unpaid. Each partial prepayment of
Principal shall be applied in inverse order of maturity to the principal
included in the installments provided for in the paragraph of the Note captioned
"Repayment of Principal and Interest."

                              BY CVC PRODUCTS, INC.
                                   IN FAVOR OF
                     MANUFACTURERS AND TRADERS TRUST COMPANY

      This RIDER, to a certain $8,000,000 Term Note, dated as of March 31, 1998,
is made by CVC PRODUCTS, INC. ("Borrower") in favor of MANUFACTURERS AND TRADERS
TRUST COMPANY ("Bank"). This Rider is an integral part of the Term Note.

      Insert No. 1. - The following is the addition to the first sentence of the
"Prepayment Premium" section of the preprinted form of this Note:

            "upon three days prior written notice received by Bank, provided
            however that the prepayment is accompanied by a Redemption Premium
            calculated as follows: The Redemption Premium shall be equal to the
            amount by which the sum of the Discounted Values (as determined
            below) of the Prepaid Installments of principal and interest on the
            Note exceeds the amount of the prepayment; but this amount shall
            never be less than 1% of the principal amount prepaid. Bank shall in
            good faith determine such Discounted Values by discounting all of
            the Prepaid Installments of principal and interest at the Applicable
            Treasury Rate (as determined below) from the date on which the
            prepayment is made through the respective scheduled payment dates.
            The Applicable Treasury Rate to be applied shall be the yield which
            is imputed from linear interpolation from current daily yields of
            U.S. Treasury obligations having maturities as close as practicable
            to the Average Life to Stated Maturity (as determined below) of the
            Prepaid Installments of principal (as of the third day prior to the
            date on which the prepayment is made) as published in the Federal
            Reserve Statistical Release H.15 (519) or if such yield is not so
            published, a similar rate based upon a comparable index as
            determined by Bank. The Average Life to Stated Maturity of the
            Prepaid Installments of principal shall be the number of months
            obtained by determining (A) the sum of the products obtained by
            multiplying (i) the amount of each Prepaid Installment of principal
            by (ii) the number of months from the date the prepayment is made
            through the scheduled payment date for such Prepaid Installment of
            principal and (B) dividing such sum by the sum of the Prepaid
            Installments of principal.

            Upon making any prepayment of the unpaid principal balance of this
            Note in full, Borrower shall also pay Bank all accrued interest and
            Expenses owing on this Note. Each partial principal prepayment shall
            be applied in inverse order

            of maturity to the principal included in the installments provided
            for in the preprinted portion of this Note labelled "Repayment of
            Principal and Interest; Late Charge.

            In the event the Maturity Date of this Note is accelerated following
            an Event of Default by the Borrower, any tender of payment of the
            amount necessary to satisfy the entire indebtedness made after such
            Event of Default shall be expressly deemed a voluntary prepayment.
            In such case, to the extent permitted by law, Bank shall be entitled
            to the amount necessary to satisfy the entire indebtedness, plus the
            appropriate prepayment premium calculated in accordance with this
            Section."

      Insert No. 1.A.

      the Loan Agreement of even date herewith between Bank and Borrower, as
amended, extended and replaced

      Insert No. 2

      or (b) any Event of Default occurs under the Loan Agreement of even date
herewith between Bank and Borrower ("Agreement"), as such Agreement is amended,
extended or replaced from time to time. Certain capitalized terms used in this
Rider have the definition given to them in the Agreement.

      Insert No. 3

      As used in this Note (i) "any agreement with the Bank" includes any
agreement, note or instrument with the Bank (which includes, without limitation,
the Agreement Note, the 1998 Grid Note and the Existing Bank Documents); (ii)
"accelerated" or "acceleration" means indebtedness that becomes due at maturity,
by notice after the occurrence of an Event of Default or which becomes due as a
result of a demand. All defined terms in the Agreement shall have the same
meaning herein unless otherwise defined herein.

      Automatically upon the commencement of Borrower's or any Guarantor's
bankruptcy if voluntary and upon lapse of forty-five (45) days without dismissal
if involuntary, all amounts outstanding hereunder shall become immediately due
and payable. Upon the occurrence of any other Event of Default hereunder, at the
Bank's option, all amounts hereunder shall become immediately due and payable.

                                   GRID NOTE

Rochester, New York As of March 31, 1998 $ 10,000,000.00

BORROWER: CVC PRODUCTS, INC. a(n) |_| individual(s) |_| partnership |X|
corporation |_| ________________ organized under the laws of Delaware Address of
residence/chief executive office: ______________________________________________

BANK: MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking corporation
with its principal banking office at One M & T Plaza, Buffalo, NY 14240.

Promise to Pay. For value received, Borrower promises to pay to the order of the
Bank on demand, the principal sum of _______________________ TEN MILLION and
00/100 Dollars ($10,000,000.00) (the "Maximum Principal Amount") or the
outstanding principal amount of this Note (the "Outstanding Principal Amount"),
if less; plus interest as agreed below and all reasonable fees and costs
(including without limitation reasonable attorneys fees and disbursements,
whether for internal or outside counsel) the Bank incurs in order to collect any
amount due under this Note, to negotiate or document a workout, or
restructuring, or to preserve its right or realize upon any guaranty or other
security for the payment of this Note ("Expenses").

Interest. The outstanding Principal Amount of this Note shall earn interest
calculated on the basis of 360-day year for the actual number of days of each
year (365 or 366) from and including the date the proceeds of this Note were
disbursed to, but not including, the date all amounts hereunder are paid in full
at a rate per year which shall on each day be:

|_| __________%.

|_| equal to the rate in effect on that day as the rate announced by the Bank as
its prime rate of interest.

|X| 1/4% above the rate in effect on that day as the rate announced by the Bank
as its prime rate of interest.

If no rate is specified above, interest shall accrue at the Maximum Legal Rate
(defined below) at all times prior to payment in full.

Payments; Late Charge; Default Rate. Payments shall be made in immediately
available United States funds at any banking office of the Bank. Absent
demand for payment in full, interest shall be due and payable monthly. If
payment is not received within five days of its due date, Borrower shall pay a
late charge equal to the greatest of (a) 5% of the delinquent amount, (b) the
Bank's then current late charge as announced by the Bank from time to time, or
(c) $50.00. In addition, if the Bank has not actually received any payment under
this Note within thirty days after its due date, from and after such thirtieth
day the interest rate for all amounts outstanding under this Note shall
automatically increase to 5% above the otherwise applicable rate per year.
Payments may be applied in any order in the sole discretion of the Bank but,
prior to demand, shall be applied first to past due interest, Expenses, late
charges, and principal payments, if any, which are past due, then to current
interest and Expenses and late charges, and last to remaining principal.

Maximum Legal Rate. It is the intent of the Bank and of Borrower that in no
event shall interest be payable at a rate in excess of the maximum rate
permitted by applicable law ( the "Maximum Legal Rate"). Solely to the extent
necessary to prevent interest under this Note from exceeding the Maximum Legal
Rate, any amounts that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically cancelled, and, if received by the Bank, shall be refunded to
Borrower.

Setoff. The Bank shall have the right to set off against the amounts owing under
this Note any property held in a deposit or other account with the Bank or
otherwise owing by the Bank in any capacity to Borrower or any guarantor or
endorser of this Note.

Authorized Representatives. This Note is issued by Borrower to the Bank in
connection with a certain line of credit or loan limit made available by the
Bank to Borrower (the "Credit"). The Bank may make any loan pursuant to the
Credit (the "Loan(s)") in reliance upon any oral, telephonic, written,
teletransmitted or other request (the "Request(s)") that the Bank in good faith
believes to be valid and to have been made by Borrower or on behalf of Borrower
by CHRISTINE WHITMAN or EMILIO DiCATALDO (each an "Authorized Person"). The Bank
may act on the Request of any Authorized Person until the Bank shall have
received from Borrower, and had a reasonable time to act on, written notice
revoking the authority of such Authorized Person. The Bank shall incur no
liability to Borrower or to any other person as a direct or indirect result of
making any Loan pursuant to this paragraph.

Demand Facility. The Bank may modify, restrict, suspend or terminate the Credit
at any time for any reason and without affecting Borrower's then existing
obligation under this Note. This is a demand Note and all Loans hereunder shall
become immediately due and payable upon demand by the Bank; provided, however,
that the Outstanding Principal Amount of this Note and all accrued and unpaid
interest shall automatically become immediately due and payable if Borrower or
any guarantor or endorser of this Note commences or has commenced against it any
bankruptcy or insolvency proceeding. Borrower hereby waives protest, presentment
and notice of any kind in connection with this Note.

Bank Records Conclusive. The Bank shall set forth on a schedule attached to this
Note or maintained on computer, the date and original principal amount of each
Loan and the date and amount of each payment to be applied to the Outstanding
Principal Amount of this Note. The Outstanding Principal Amount set forth on any
such schedule shall be presumptive evidence of the Outstanding Principal Amount
of this Note and of all Loans. No failure by the Bank to make, and no error by
the Bank in making, any annotation on any such schedule shall affect Borrower's
obligation to pay the principal and interest of each Loan or any other
obligation of Borrower to the Bank pursuant to this Note.

Purpose. Borrower certifies (a) that no Loan will be used to purchase margin
stock except with the Bank's express prior written consent for each such
purchase and (b) that all Loans shall be used for a business purpose, and not
for any personal, family or household purpose, unless the following box is
checked:

|_| Personal Loan. If this box is check, the initial advance must be an amount
greater than $25,000.

Authorization. Borrower, if a corporation, partnership, trust or other entity,
represents that it is duly organized and in good standing or duly constituted in
the state of its organization and is duly authorized to do business in all
jurisdictions material to the conduct of its business; that the execution,
delivery and performance of this Note have been duly authorized by all necessary
regulatory and corporate or partnership action or by its governing instrument;
that this Note has been duly executed by an authorized officer, partner or
trustee and constitutes a binding obligation enforceable against Borrower and
not in violation of any law, court order or agreement by which Borrower is
bound; and that Borrower's performance is not threatened by any pending or
threatened litigation.

<PAGE>

Miscellaneous. This Note, together with any related loan and security
agreements, contains the entire agreement between the Bank and Borrower with
respect to each Loan, and supersedes every course of dealing, other conduct,
oral agreement and representation previously made by the Bank. The Bank's rights
and remedies under applicable law and this Note are cumulative and not
exclusive. No single, partial or delayed exercise by the Bank of any right or
remedy shall preclude the subsequent exercise by the Bank at any time of any
right or remedy of the Bank without notice. No waiver or amendment of any
provision of this Note shall be effective unless made specifically in writing by
the Bank. This Note shall be governed by the laws of the State of New York,
without regard to its principles of conflict of laws. This Note is a binding
obligation enforceable against Borrower and its successors and assigns and shall
inure to the benefit of the Bank and its successors and assigns. If a court
deems any provision of this Note invalid, the remainder of the Note shall remain
in effect. Section heading are for convenience only. Singular number includes
plural and neuter gender includes masculine and feminine as appropriate.

Joint and Several. If Borrower is more than one person, each such person is
jointly and severally liable for all amounts which become due under this
Note.

Borrower's Consents. In any action or other legal proceeding relating to this
Note, Borrower (a) consents to the personal jurisdiction of any State or federal
court location in the State of New York, and (b) agrees that a copy of this Note
kept in the Bank's course of business may be admitted into evidence as an
original.

WAIVER OF JURY TRIAL. BORROWER AND THE BANK EACH WAIVE ANY RIGHT TO TRIAL BY
JURY IN ANY ACTION IN CONNECTION WITH THIS NOTE.

|X| Replacement Note. This Note is given in partial replacement of and in
substitution for, but not in payment of, two 800 Notes heretofore executed by
Borrower in favor of Bank, as further specified in an Application of Proceeds
executed by Borrower on the date this Note was executed.

Preauthorized Transfers from Deposit Account. If a deposit account number is
provided in the following blank Borrower hereby authorizes the Bank to debit
available funds in Borrower's deposit account # 15226103 with the Bank
automatically for any amount which becomes due under this Note or as directed by
an Authorized Person, by telephone.

or jointly with other borrowers, even if not evidenced by a writing, and even if
periodically extinguished and reincurred (the "Obligations"). Guarantor will pay
or perform its obligations under this Guaranty upon demand. This is a guaranty
of payment, not collection.

Guaranty and acknowledges that the Bank is relying on this Guaranty in making a
financial accommodation to Borrower, whether a commitment to lend, extension,
modification or replacement of, or forbearance with respect to, any Obligation,

also constitute consideration for this Guaranty.

      2. Continuing, Unconditional and Unlimited Guaranty. This Guaranty is
irrevocable, continuing, unconditional and general without any limitation.

      3. Guarantor's Waivers. (a) Guarantor's obligations shall not be released,
impaired or affected in any way by (i) Borrower's bankruptcy, reorganization or
insolvency under any law or that of any other party, or by any action of a
trustee in any such proceeding; (ii) failure of any other party to perform its
obligations to the Bank; or (iii) any other circumstance that might constitute a
legal or equitable defense to Guarantor's or Borrower's obligations under this
Guaranty, including without limitation: (A) any new agreements or obligations of
Borrower with or to the Bank, amendments, changes in rate of interest,
extensions of time for payments, modifications, renewals or the existence of or

other party with the Bank; (B) any adjustment, compromise or release of any
Obligations of Borrower, by the Bank or any other party; the existence or
nonexistence or order of any filings, exchanges, releases, impairment or sale

create an accord and satisfaction with respect to any of the Obligations; (C)
any fictitiousness, incorrectness, invalidity or unenforceability, for any
reason, of any instrument or other agreement, or act of commission or omission
by the Bank or Borrower; (D) any composition, extension, moratoria or other
statutory relief granted to Borrower; or (E) any interruption in the business
relations between the Bank and Borrower, or any dissolution or change in form of

Banks reliance on or enforcement of this Guaranty.

Guaranty, Guarantor irrevocably waives, without notice, any right it may have at
law or in equity (including without limitation any law subrogating Guarantor to
the rights of the Bank) to seek contribution, indemnification or any other form
of reimbursement from Borrower or any other obligor or guarantor of the
Obligations for any disbursement made under this Guaranty or otherwise.

      4. Termination; Reinstatement. This Guaranty can be terminated (a) only
with respect to Obligations not yet incurred, and (b) only by actual receipt by
the Bank officer named above of written notice of Guarantor's intent to
terminate (or Guarantor's dissolution) plus (c) the lapse of a reasonable time
for Bank to act on such notice. This Guaranty cannot be terminated with respect
to any Obligations committed or contracted for or outstanding at the time the
Bank acts on such notice, or any prior or subsequent modifications, renewals,
extensions or replacements of or interest on such Obligations, or related
expenses. If any payment the Bank has received prior to termination subsequently
is declared fraudulent or preferential or for any other reason required to be
surrendered, Guarantor's obligations under this Guaranty and any related
security agreements shall be reinstated and remain in effect until the Bank has
actually received payment in full of the Obligations.

and all costs, damages, liabilities and expenses which may be incurred by the

other action or failure to act in connection with this Patent Agreement or the

                                      -5-
<PAGE>

      6.2 Assignors' Duties, Etc.

            The Assignors shall have the duty, through patent counsel acceptable
to the Bank, to prosecute diligently any patent applications of the Patents
pending as of the date of this Patent Agreement or thereafter, to make
application for unpatented but reasonably patentable inventions and to preserve
and maintain all rights in the Patents, including without limitation the payment
when due of all maintenance fees and other fees, taxes and other expenses which
shall be incurred or which shall accrue with respect to any of the Patents. Any
expenses incurred in connection with such applications and actions shall be
borne by the Assignors. The Assignors shall not abandon any filed patent
application, or any pending patent application or patent, without the consent of
the Bank, which consent shall not be unreasonably withheld. The Bank hereby
appoints the Assignors as its agent for all matters referred to in the foregoing
provisions of this Section 6 and agrees to execute any documents necessary to
confirm such appointment. Upon the occurrence and during the continuance of an
Event of Default, the Bank may terminate such agency by providing written notice
of termination to the Assignors. The Bank shall not unreasonably delay in
responding to any written inquiry as to the acceptability of patent counsel
pursuant to this Section 6.2 or the abandonment of any patent application.

      6.3 Assignors' Enforcement Rights.

            The Assignors shall have the right, with the consent of the Bank,
which shall not be unreasonably withheld, to bring suit or other action in the
Assignors' own name(s) to enforce the Patents and the Patent Rights. The Bank
shall be required to join in such suit or action as may be necessary to assure
the Assignors' ability to bring and maintain any such suit or action in any
proper forum so long as the Bank is completely satisfied that such joinder will
not subject the Bank to any risk of liability. The Assignors shall promptly,
upon demand, reimburse and indemnify the Bank for all damages, costs and
expenses, including legal fees, incurred by the Bank pursuant to this Section 6.

      6.4 Protection of Patents, Etc.

            In general, the Assignors shall take any and all such actions
(including but not limited to institution and maintenance of suits, proceedings
or actions) as may be necessary or appropriate to properly maintain, protect,
preserve, care for and enforce the Patent Collateral. The Assignors shall not
take or fail to take any action, nor permit any action to be taken or not taken
by others under their control, which would affect the validity, grant or
enforcement of any of the Patent Collateral.

      6.5 Notification by Assignors.

            Promptly upon obtaining knowledge thereof, the Assignors will notify
the Bank in writing of the institution of, or any final adverse determination
in, any proceeding in the PTO or any similar office or agency of the United
States or any foreign country, or any court, regarding the validity of any of
the Patents or the Assignors' rights, title or interests in and to any of the
Patent Collateral, and of any event which does or


                                      -6-
<PAGE>

reasonably could materially adversely affect the value of any of the Patent
Collateral, the ability of the Assignors or the Bank to dispose of any of the
Patent Collateral or the rights and remedies of the Bank in relation thereto
(including, but not limited to, the levy of any legal process against any of the
Patent Collateral).

7. LICENSE BACK TO ASSIGNORS.

      Unless and until there shall have occurred and be continuing an Event of
Default and the Bank has notified the Assignors that the license granted
hereunder is terminated, the Bank hereby grants to the Assignors the sole and
exclusive, nontransferable, royalty-free, worldwide right and license under the
Patents to make, have made for them, use, sell and otherwise practice the
inventions disclosed and claimed in the Patents for the Assignors' own benefit
and account and for none other; provided, however, that the foregoing right and
license shall be no greater in scope than, and limited by, the rights assigned
to the Bank by the Assignors hereby. The Assignors agree not to sell, assign,
transfer, encumber or sublicense their interest in the license granted to the
Assignors in this Section 7, without the prior written consent of the Bank. Any
such sublicenses granted on or after the date hereof shall be terminable by the
Bank upon termination of the Assignors' license hereunder.

8. REMEDIES.

      If any Event of Default shall have occurred and be continuing, then upon
notice by the Bank to the Assignors: (i) the Assignors' license with respect to
the Patents as set forth in Section 7 shall terminate; (ii) the Assignors shall
immediately cease and desist from the practice, manufacture, use and sale of the
inventions claimed, disclosed or covered by the Patents; and (iii) the Bank
shall have, in addition to all other rights and remedies given it by this Patent
Agreement, the Loan Agreement, the Security Agreements, and all other
agreements, instruments and documents executed by Borrower and/or Parent in
favor of Bank at any time, those allowed by law and the rights and remedies of a
secured party under the Uniform Commercial Code as enacted in the State of New
York and, without limiting the generality of the foregoing, the Bank may
immediately, without demand of performance and without other notice (except as
set forth next below) or demand whatsoever to the Assignors, all of which are
hereby expressly waived, and without advertisement, sell or license at public or
private sale or otherwise realize upon the whole or from time to time any part
of the Patent Collateral, or any interest which the Assignors may have therein,
and after deducting from the proceeds of sale or other disposition of the Patent
Collateral all reasonable expenses (including all reasonable expenses for
broker's fees and legal services), shall apply the residue of such proceeds
toward the payment of the Obligations as set forth in the Security Agreements.
Notice of any sale, license or other disposition of any of the Patent Collateral
shall be given to the Assignors at least five (5) days before the time that any
intended public sale or other disposition of such Patent Collateral is to be
made or after which any private sale or other disposition of such Patent
Collateral may be made, which the Assignors hereby agrees shall be reasonable
notice of such public or private sale or


                                      -7-
<PAGE>

other disposition. At any such sale or other disposition, the Bank may, to the
extent permitted under applicable law, purchase or license the whole or any part
of the Patent Collateral or interests therein sold, licensed or otherwise
disposed of.

9. COLLATERAL PROTECTION.

      If the Assignors shall fail to do any act that they have covenanted to do
hereunder, or if any representation or warranty of the Assignors shall be
breached, the Bank, in their own name or that of the Assignors (in the sole
discretion of the Bank), may (but shall not be obligated to) do such act or
remedy such breach (or cause such act to be done or such breach to be remedied),
and the Assignors agree promptly to reimburse the Bank for any cost or expense
incurred by the Bank in so doing.

10. POWER OF ATTORNEY.

      If any Event of Default shall have occurred and be continuing, the
Assignors do hereby make, constitute and appoint the Bank (and any officer or
agent of the Bank as the Bank may select in its exclusive discretion) as the
Assignors' true and lawful attorney-in-fact, with the power to endorse the
Assignors' name on all applications, documents, papers and instruments necessary
for the Bank to use any of the Patent Collateral, to practice, make, use or sell
the inventions disclosed or claimed in any of the Patent Collateral, to grant or
issue any exclusive or nonexclusive license of any of the Patent Collateral to
any third person, or necessary for the Bank to assign, pledge, convey or
otherwise transfer title in or dispose of the Patent Collateral or any part
thereof or interest therein to any third person, and, in general, to execute and
deliver any instruments or documents and do all other acts which the Assignors
are obligated to execute and do hereunder. The Assignors hereby ratify all that
such attorney shall lawfully do or cause to be done by virtue hereof, and
releases the Bank from any claims, liabilities, causes of action or demands
arising out of or in connection with any action taken or omitted to be taken by
the Bank under this power of attorney (except for the Bank's gross negligence or
willful misconduct). This power of attorney shall be irrevocable for the
duration of this Patent Agreement.

11. FURTHER ASSURANCES.

      The Assignors shall, at any time and from time to time, and at their
expense, make, execute, acknowledge and deliver, and file and record as
necessary or appropriate with governmental or regulatory authorities, agencies
or offices, such agreements, assignments, documents and instruments, and do such
other and further acts and things (including, without limitation, obtaining
consents of third parties), as the Bank may request or as may be necessary or
appropriate in order to implement and effect fully the intentions, purposes and
provisions of this Patent Agreement, or to assure and confirm to the Bank the
grant, perfection and priority of the Bank's security interest in any of the
Patent Collateral.


                                      -8-
<PAGE>

12. TERMINATION.

      At such time as all of the Obligations have been finally paid and
satisfied in full and neither of the Assignors have any right to request
advances from Bank under a line of credit, this Patent Agreement shall terminate
and the Bank shall, upon the written request and at the expense of the
Assignors, execute and deliver to the Assignors all deeds, assignments and other
instruments as may be necessary or proper to reassign and reconvey to and
re-vest in the Assignors the entire right, title and interest to the Patent
Collateral previously granted, assigned, transferred and conveyed to the Bank by
the Assignors pursuant to this Patent Agreement, as fully as if this Patent
Agreement had not been made, subject to any disposition of all or any part
thereof which may have been made by the Bank pursuant hereto or the Security
Agreements.

13. COURSE OF DEALING.

      No course of dealing among the Assignors and the Bank, nor any failure to
exercise, nor any delay in exercising, on the part of the Bank, any right, power
or privilege hereunder or under the Security Agreements shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or thereunder preclude any other or further exercise thereof
or the exercise of any other right, power or privilege.

14. EXPENSES.

      Any and all reasonable fees, costs and expenses, of whatever kind or
nature, including the reasonable attorneys' fees and legal expenses incurred by
the Bank in connection with the preparation of this Patent Agreement and all
other documents relating hereto, the consummation of the transactions
contemplated hereby or the enforcement hereof, the filing or recording of any
documents (including all taxes in connection therewith) in public offices, the

Assignors.

      Until paid, all amounts due and payable by the Assignors hereunder shall
be a debt secured by the Patent Collateral and other Collateral and shall bear,
whether before or after judgment, interest at the rate of interest for overdue
principal set forth in the Loan Agreement.


                                      -9-

16. NO ASSUMPTION OF LIABILITY; INDEMNIFICATION.

      NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, THE BANK
ASSUMES NO LIABILITIES OF THE ASSIGNORS WITH RESPECT TO ANY CLAIM OR CLAIMS
REGARDING THE ASSIGNORS' OWNERSHIP OR PURPORTED OWNERSHIP OF, OR RIGHTS OR
PURPORTED RIGHTS ARISING FROM, ANY OF THE PATENT COLLATERAL OR ANY PRACTICE,
USE, LICENSE OR SUBLICENSE THEREOF, OR ANY PRACTICE, MANUFACTURE, USE OR SALE OF

or concurrently. This Patent Agreement is supplemental to the Security
Agreements, and nothing contained herein shall in any way derogate from any of

Patent Agreement shall be deemed to extend the time of attachment or perfection
of or otherwise impair the security interest in any of the Patent Collateral
granted to the Bank under the Security Agreements.

19. AMENDMENT AND WAIVER.

      This Patent Agreement is subject to modification only by a writing signed
by the Bank and the Assignors, except as provided in Section 5.2. The Bank shall
not be deemed to have waived any right hereunder unless such waiver shall be in
writing and signed by the Bank. A waiver ss.2 any one occasion shall not be
construed as a bar to or waiver of any right on any future occasion.

20. GOVERNING LAW; CONSENT TO JURISDICTION.

      THIS PATENT AGREEMENT IS INTENDED TO TAKE EFFECT AS A SEALED INSTRUMENT
AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE
STATE OF NEW YORK. The Assignors agree that any suit for the enforcement of this
Patent Agreement may be brought in the courts of the County of Monroe or any
federal court sitting therein and consents to the non-exclusive jurisdiction of
such court and to service of process in any such suit being made upon the
Assignors by mail at the address specified in Section 18. The Assignors hereby
waive any objection that they may now or hereafter have to the venue of any such
suit or any such court or that such suit is brought in an inconvenient court.

21. WAIVER OF JURY TRIAL.

      THE ASSIGNORS WAIVE THEIR RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION
OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS PATENT AGREEMENT,
ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR
OBLIGATIONS. Except as prohibited by law, the Assignors waive any right which
they may have to claim or recover in any litigation referred to in the preceding
sentence any special, exemplary, punitive or consequential damages or any
damages other than, or in addition to, actual damages. The Assignors (i) certify
that neither the Bank nor any representative, agent or attorney of the Bank has
represented, expressly or otherwise, that the Bank would not, in the event of
litigation, seek to enforce the foregoing waivers, and (ii) acknowledges that,
in entering into the Loan Agreement and the other agreements, notes, instruments
and documents executed in connection therewith to which the Bank is a party, the
Bank is relying upon, among other things, the waivers and certifications
contained in this Section 21.

22. BANK'S RIGHT TO ACCEPT OR CONSENT, ETC.

      Notwithstanding anything herein to the contrary, Bank shall not be deemed
to have unreasonably delayed in responding to a request for a consent hereunder
or the approval of a counsel proposed by Assignors whom the Bank must consent to
unless Bank fails to respond to a request for such consent or acceptance of
proposed counsel for 10 days after such request is submitted and Assignors
thereafter notify Bank in writing that they believe Bank has unreasonably
delayed in responding to such request and Bank continues for more than 10 days
after its receipt of such notice to respond to such request. In any event, the
sole remedy for Assignors if Bank unreasonably delayed in responding to any such
request shall be that it loses its right to consent to any such action or to
approve any such counsel.

23. MISCELLANEOUS.

      The headings of each section of this Patent Agreement are for convenience
only and shall not define or limit the provisions thereof. This Patent Agreement
and all rights and obligations hereunder shall be binding upon the Assignors and
their respective successors and permitted assigns, and shall inure to the
benefit of the Bank and its successors and assigns. In the event of any
irreconcilable conflict between the provisions of this Patent Agreement and the
Loan Agreement, or between this Patent Agreement and the Security Agreements,
the provisions of the Loan Agreement or the Security Agreements, as the case may
be, shall control. If any term of this Patent Agreement shall be held to be
invalid, illegal or unenforceable, the validity of all other terms hereof shall
in no way be affected thereby, and this Patent Agreement shall be construed and
be enforceable as if such invalid, illegal or unenforceable term had not been
included herein. The Assignors acknowledge receipt of a copy of this Patent
Agreement. All obligations of the Assignors hereunder shall be joint and
several.

      IN WITNESS WHEREOF, this Patent Agreement has been executed as of the day
and year first above written.

            To secure the payment and performance in full of any and all
Obligations, the Assignors hereby grant, assign, transfer and conveys to the

            Pursuant to the Security Agreements the Assignors have granted to
the Bank a continuing security interest in and lien on the Collateral (including
the Pledged Trademarks). The Security Agreements, and all rights and interests
of the Bank in and to the Collateral (including the Pledged Trademarks)
thereunder, are hereby ratified and confirmed in all respects. In no event shall
this Trademark Agreement, the grant, assignment, transfer and conveyance of the
Pledged Trademarks hereunder, or the recordation of this Trademark Agreement (or
any document hereunder) with the PTO, adversely affect or impair, in any way or
to any extent, the Security Agreements, the security interest of the Bank in the
Collateral (including the Pledged Trademarks) pursuant to the Security
Agreements and this Trademark Agreement, the attachment and perfection of such

provided herein, or arising hereunder or in connection herewith, shall only
supplement and be cumulative and in addition to the rights and interests of the
Bank (and the obligations of the Assignor) in, to or with respect to the
Collateral (including the Pledged Trademarks) provided in or arising under or in
connection with the Security Agreements and shall not be in derogation thereof.

hereunder is terminated, the Bank hereby grants to the Assignors the sole and
exclusive, nontransferable, royalty-free, worldwide right and license under the
Trademarks to make, have made for them, use, sell and otherwise practice the

to be taken or not taken by others under its control, that would adversely

Obligations as set forth in or by reference in the Security Agreements. Notice
of any sale, license or other disposition of the Pledged Trademarks shall be

public sale or other public disposition of the Pledged Trademarks is to be made
or after which any private sale or other private disposition of the Pledged

be done by virtue hereof and releases the Bank from any claims, liabilities,
causes of action or demands arising out of or in connection with any action
taken or omitted to be taken by the Bank under this power of attorney (except

appropriate in order to implement and effect fully the intentions, purposes and
provisions of this Trademark Agreement, or to assure and confirm to the Bank the
grant, perfection and priority of the Bank's security interest in the Pledged
Trademarks.

satisfied in full and neither of the Assignors have any rights to request an
advance under any line of credit and all lines of credit provided by Bank have

all or any part thereof that may have been made by the Bank pursuant hereto or
the Security Agreements.

to exercise, nor any delay in exercising, on the part of the Bank, any right,
power or privilege hereunder or under the Security Agreements or any other
agreement shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or thereunder preclude any
other or further exercise thereof or the exercise of any other right, power or

      CVC has no prior opinions or similar documents relating to the scope or
validity of its trademarks. No maintenance fees are presently due for CVC's
existing CONNEXION(R) trademark registration. In addition, there are no
documents relating to litigation or licenses involving CVC's trademarks, related
foreign filings, and product-line information related to the trademarks.

      3. CVC's Foreign Trademark Assets. To date, CVC holds no foreign trademark
registrations. Nor does CVC, as of the date of this Intellectual Property Audit
Report, have pending any foreign trademark applications. To the extent that CVC
uses a particular mark for a product it sells in a foreign market, those marks
appearing in Table 5, above, represent the only marks CVC uses outside the
United States.

            There are no prior opinions or documents relating to the scope or
validity of CVC's trademarks outside the United States. Nor are there any
foreign patent and trademark office actions or maintenance fee dates due at this
time. No documents relating to litigation or licenses involving CVC's
trademarks, related foreign filings, and product-line information related to the
use of trademarks outside the United States were discovered in this Intellectual
Property Audit.

E. Copyright Assets and Related Intellectual Property Assets

      1. Overview. The Copyright Act establishes copyright protection "in
original works of authorship fixed in any tangible medium of expression." Each
word in this phrase must be satisfied in order to create a copyright. The work
must be original, meaning that it was created by the author--that is, it
"originated" with the author, not someone else but it need not be highly unique
or creative, which is required for some other forms of intellectual property
protection, such as patents. A work must be fixed in some tangible way in order
to create a copyright. Authors cannot simply come up with brilliant ideas for
books or songs and carry them

THIS SUBORDINATION AGREEMENT (this "Agreement") is made and entered into by and
between Security Capital Industrial Trust, a Maryland Real Estate Investment
Trust, ("Landlord"), and Manufacturers and Traders Trust Company ("Lender") as
of the _______ day of April, 1998.

                                   WITNESSETH:

Whereas, Landlord and CVC Holdings, Inc. a Delaware Corporation ("Tenant") have
entered into that certain lease dated November 7, 1995, (the "Lease") pursuant
to which Tenant is leasing certain premises located at $100 Laurelview Court,
Fremont, CA (the "Premises") from Landlord;

Whereas, pursuant to the Landlord's Lien/Security Agreement provision of the
Lease if any, or California law, Tenant has granted to Landlord a [ILLEGIBLE] of
Tenant's personal property ("Personal Property") located in the Premises
(collectively, the "Landlord's Lien");

Whereas, in connection with the Tenant obtaining a line of credit or providing
any financing or refinancing for the purchase of any personal property for the
Premises ("Personal Property Financing") with Lender, Tenant has requested, and
Landlord has agreed, subject to certain conditions, to subordinate the
Landlord's Lien to any personal property liens of Lender.

NOW, THEREFORE, in consideration of the [ILLEGIBLE] covenants contained herein,
and for other consideration, the receipt and sufficiency of which is hereby
acknowledged, Landlord, Tenant and Lender hereby agree as follows:

      1.    Notwithstanding the Landlord's Lien/Security Agreement provision of
            the Lease if any, or any provisions of California law, the
            Landlord's Lien shall be subordinate and subject to the lien placed
            on the Personal Property by the Lender in connection with the
            Personal Property Financing.

      2.    Lender hereby agrees that it shall not occupy and/or possess the
            Premises for more than a fourteen (14) day period.

      3.    Lender hereby agrees that it shall indemnify and hold Landlord
            harmless from any liability, loss, cost, damage caused while in
            possession of the Premises and/or expenses (including, without
            limitation, Landlord's attorneys' fees) incurred by or asserted
            against Landlord arising out of any action by or on behalf of the
            Lender in connection with Lender's enforcement action involving
            Tenant's Personal Property.

      4.    Lender hereby agrees that it shall be required to repair any damage
            to the Premises caused by Lender, or Lender's agents, during the
            period in which it is in possession of the Premises.

      5.    Lender, or Lender's agents, shall not hold any auction or sale of
            the Personal Property on the Premises.

      6.    This Agreement shall in all respects be a continuing agreement and
            shall remain in full force and effect so long as the Personal
            Property Financing is in effect and so long as the Tenant (or the
            Lender) occupies or is in possession of the Premises.

      7.    The term Tenant includes CVC Holdings, Inc.'s wholly owned
            subsidiary, CVC Products, Inc.

      IN WITNESS WHEREOF, this Agreement has been executed and delivered by the
Lender and the Landlord as of the day and year first written above.

      IN WITNESS WHEREOF, CVC Holding, Inc. has caused this Certificate to be
signed by Christine B. Whitman, its President, this 15th day of October, 1997.

                              CVC HOLDINGS, INC.

                                         Meeting of the Board of Directors
                                         of CVC, Inc.
                                         October 14, 1997

            The Meeting was called to order by telephonic conference at 4:00
p.m. by Christine Whitman, Chairman of the Board. Ms. Whitman, James Geater,
Victor Mann, Seiya Miyanishi, Andrew Peskoe and Donald Waite were in attendance,
representing a quorum of the Board of Directors. Brendan Hegarty was not
immediately available. Ms. Whitman served as Chairman of the Meeting and
requested that Mr. Peskoe serve as Secretary. Also attending at the request of
the Board were Emilio DiCataldo and Frederick Kanner.

            Ms. Whitman introduced the first order of business: the
consideration of minutes for the August 26, 1997 meeting previously circulated
to the Board. Mr. Waite suggested two modifications, which were accepted and, as
so modified, such minutes were unanimously adopted.

            In response to Mr. Waite's inquiry, Ms. Whitman briefed the Board on
the status of Veeco and Lam discussions and the most recent communications. Mr.
Waite expressed his view that such efforts constituted adequate diligence at
this time, and requested that any meaningful offer be given due consideration in
the future.

            Mr. Kanner outlined the proposed Certificate of Amendment to the
Certificate of Incorporation (the "Amendment") of the corporation, including the
change of name, increase in authorized shares, and increase in Board size. The
Board discussed that the insertion of "blank check" preferred stock would be
considered at a later meeting. The Board also agreed to reconsider increasing
the authorized common shares to 100 million based on the estimate of franchise
taxes to be obtained by Mr. DiCataldo. The Board also discussed and concurred
that the minimum Board size would be set at three with the actual Board size
determined by the Board and that the initial Board was set at eight effective
upon filing of the Amendment.

            Mr. Hegarty joined the telephone meeting at this juncture. Ms.
Whitman nominated Robert Fink to fill the vacancy on the Board to be created by
the increase in Board size. The Board discussed his qualifications, particularly
his experience in the semiconductor equipment industry, his operating (and
inventory control) experience and his public company experience. It was
resolved, after motion duly made and seconded, that upon filing of the
Amendment, the Board be increased from 7 to 8 and that upon Common Stockholder
and Class A Preferred Stockholder approval, Mr. Fink be so elected as a
director. It was further resolved that Mr. Fink serve on the Compensation
Committee upon his appointment to the Board.

            The Board discussed and approved a three for one stock split
effective October 31, 1997.

            The Board discussed and authorized the filing of a Registration
Statement on Form S-1, contemplating an offering (on a firm commitment basis) of
3 million shares by the Company and 900,000 shares by Anne Whitman with a 15%
over allocation to the underwriters (resulting in a maximum sale by the Company
of 3,585,00 shares).

            The Board discussed and approved the appointment of: Boston
Equiserve as transfer agent for the Company's shares, and the Pricing Committee
for the proposed offering of Ms. Whitman, Mr. Fink, Mr. Miyanishi and Mr. Waite.

            The Board next turned to stock option plan matters, discussing and
approving a new Non-employee Director Stock Option Plan (previously distributed
to the directors) providing initial grants of 10,000 (post-split) options to new
non-employee directors, annual 3,000 (post-split) option grants to each
non-employee director and maximum option grants of 250,000, and the 1997 Stock
Option Plan for key employees (previously distributed to the directors) with
maximum grants of 1,250,000 options. It was pointed out that both plans had been
reviewed in advance by the Compensation Committee, which was recommending they
be approved by the full Board. For the Director Plan it was resolved that the
exercise price of grants allocated before the contemplated offering be set at
the offering price.

            The Board discussed the proposed Employment Agreements for
executives (previously distributed to the Board) and the terms contemplated. The
Board requested advice as to certain labor law and accounting issues and Mr.
Kanner and Mr. DiCataldo undertook to obtain such advice. The Board approved
these agreements with the modification that the option extension on a change of
control be limited to 12 months, and with the provision that the labor law and
tax issues be resolved. These agreements were approved first without and then
with Ms. Whitman voting, as she was an employment agreement signatory.

            The Board discussed and approved the draft director Indemnification
Agreements (previously distributed to the Board).

            The Board discussed and ratified the sales and grants of options
made outside the formal stock option plans from the inception of the
Corporation, set forth in the schedules distributed, such ratification was
approved without Ms. Whitman and Mr. Peskoe voting and then with their vote as
each was an optionee.

            The Board nominated and elected Mr. DiCataldo as an assistant
secretary of the corporation and of CVC Products, Inc.

            (the "Series B Preferred"). The Series A Preferred and the Series B
            Preferred shall collectively be referred to as the "Preferred
            Stock."

                             RESTATED CERTIFICATE OF

                                INCORPORATION OF

                               CVC HOLDINGS, INC.

                                    Article I

      The name of the Corporation is CVC Holdings, Inc.

                                   Article II

      The address of the Corporation's registered office in the State of
Delaware is 32 Loockerman Square, Suite L-100, in the City of Dover, County of
Kent. The name of its registered agent at such address is The Prentice-Hall
Corporation System, Inc.

                                   Article III

      The purpose of the corporation is to engage in any lawful act or activity
for which corporations may be organized under the General Corporation Law of the
State of Delaware.

                                   Article IV

      (a) The Corporation is authorized to issue two classes of stock,
designated "Common Stock" and "Preferred Stock." The total number of shares
which the Corporation is authorized to issue is 1,602,500. The total number of
shares of Common Stock which the Corporation is authorized to issue is
1,500,000, par value $.0l per share. The total number of shares of Preferred
Stock which the Corporation is authorized to issue is 102,500, par value $.0l
per share, of which 2,500 shares shall be designated 8% Non-Cumulative
Convertible Preferred Stock (the "Series A Preferred") and 100,000 shares shall
be designated Series B Non-Cumulative Convertible Preferred Stock (the "Series B
Preferred"). The Series A Preferred and the Series B Preferred shall
collectively be referred to as the "Preferred Stock."

      The Corporation shall from time to time in accordance with the laws of the
State of Delaware increase the authorized amount of its Common Stock if at any
time the number of shares of Common Stock remaining unissued and available for
issuance shall not be sufficient to permit conversion of the Preferred Stock.

      The relative rights, preferences, privileges and restrictions granted to
or imposed upon the Preferred Stock and the Common Stock or the holders thereof
are as follows:

      Section 1. Dividends. The holders of the Series A Preferred and Series B
Preferred shall be entitled to receive, when and as declared by the Board of
Directors, dividends at the rate of $80.00 per share for Series A Preferred and
$11.90 per share for Series B Preferred (in each case as adjusted for any stock
splits, stock dividends, recapitalizations and the like with respect to such
shares) per annum as the Board of Directors may from time to time determine out
of funds legally available therefor. No dividends shall be paid on the Series A
Preferred during any fiscal year of the Corporation until dividends in the total
amount of $11.90 per share on the Series B Preferred shall have been paid or
declared and set apart during that fiscal year. No dividends (other than those
payable solely in the Common Stock of the Corporation) shall be paid on any
Common Stock of the Corporation during any fiscal year of the Corporation until
dividends in the total amount of $80.00 per share of Series A Preferred and
$11.90 per
<PAGE>

share of Series B Preferred (in each case as adjusted for any stock splits,
stock dividends, recapitalizations and the like with respect to such shares)
shall have been paid or declared and set apart during that fiscal year. The
right to such dividends on shares of Preferred Stock shall not be cumulative,
and no right shall accrue to holders of Preferred Stock by reason of the fact
that dividends on said shares are not declared in any prior year.

      After payment of such dividends to the holders of the Preferred Stock, any
additional dividends declared shall be distributed among all the holders of the
Common Stock.

      Section 2. Liquidation Preference. In the event of any liquidation,
dissolution, or winding up of the Corporation, either voluntary or involuntary,
distributions to the stockholders of the Corporation shall be made in the
following manner:

            (a) The holders of the Series B Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of the Series A Preferred and
the Common Stock by reason of their ownership of such stock, the amount equal to
the sum of (i) $148.78 per share for each share of Series B Preferred then held
by them (as adjusted for stock splits, stock dividends, recapitalizations and
the like with respect to such stock), and (ii) an amount equal to all declared
but unpaid dividends or distributions on the Series B Preferred. If the assets
and funds thus distributed among the holders of the Series B Preferred pursuant
to this Section 2(a) shall be insufficient to permit the payment to such holders
of the full aforesaid preferential amount, then the entire assets and funds of
the Corporation legally available for distribution shall be distributed ratably
among the holders of the Series B Preferred in proportion to the preferential
amount that each such holder is otherwise entitled to receive.

            (b) After payment has been made to the holders of the Series B
Preferred of the full amounts to which they shall be entitled as set forth in
the first sentence of Section 2(a), then the holders of the Series A Preferred
shall be entitled to receive the amount equal to the sum of (i) $1,000 per share
for each share of Series A Preferred then held by them (as adjusted for stock
splits, stock dividends, recapitalizations and the like with respect to such
stock), and (ii) an amount equal to declared but unpaid dividends or
distributions on the Series A Preferred. If the assets and funds thus
distributed among the holders of the Series A Preferred pursuant to this Section
2(b) shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amount, then the entire assets and funds of the
Corporation legally available for distribution pursuant to this Section 2(b)
shall be distributed ratably among the holders of the Series A Preferred in
proportion to the preferential amount that each such holder is otherwise
entitled to receive.

            (c) After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled as set forth in
Section 2(a) and in Section 2(b) above, then the entire remaining assets and
funds of the Corporation legally available for distribution, if any, shall be
distributed on a pro rata basis on the outstanding Common Stock.

            (d) For purposes of this Section 2, a merger or consolidation of the
Corporation with or into any other corporation or corporations, or the merger of
any other corporation or corporations into the Corporation (other than any
merger or consolidation in which stockholders of the Corporation immediately
prior to such merger or consolidation beneficially own a majority of the voting
shares of the surviving corporation immediately following such merger or
consolidation), or a sale of all or


                                       -2-
<PAGE>

substantially all of the assets of the Corporation, shall be treated as a
liquidation, dissolution or winding up of the Corporation.

            (e) Any securities to be delivered to the holders of the Preferred
Stock and Common Stock upon a merger, reorganization or sale of substantially
all the assets of the Corporation shall be valued as follows:

                  (1) if traded on a securities exchange or on the NASDAQ Stock
Market, the value shall be deemed to be the average of the closing prices of the
securities on such exchange over the ten business day period ending three (3)
business days prior to the closing of such merger, reorganization or sale;

                  (2) if actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid prices over the ten business day
period ending three (3) business days prior to the closing; and

                  (3) if there is no active public market, the value shall be
the fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of Series B
Preferred voting as a single class, provided that if the Corporation and the
holders of a majority of the outstanding shares of Series B Preferred are unable
to reach agreement, then by independent appraisal by an investment banker hired
and paid by the Corporation, but reasonably acceptable to the holders of a
majority of the outstanding shares of Series B Preferred voting as a single
class.

      Section 3. Redemption of Series B Preferred.

            (a) At the individual option of each holder of shares of Series B
Preferred, the Corporation shall redeem, on March 31, 2002 (the "Redemption
Date"), the number of shares of Series B Preferred held by such holder that is
specified in a request (the "Redemption Request") for redemption delivered to
the Corporation by the holder on or prior to March 1, 2002, by paying in cash
therefor, $148.78 per share of Series B Preferred (as adjusted for stock splits,
stock dividends, recapitalizations and the like with respect to such shares)
plus all declared but unpaid dividends on such shares (the "Redemption Price").

            (b) At least 10 but no more than 20 days prior to the Redemption
Date written notice shall be mailed, first class postage prepaid, to each holder
of the Series B Preferred which has given the Corporation a Redemption Request
at the address set forth in the Redemption Request, notifying such holder of the
place at which payment may be obtained on the Redemption Date for the shares of
Series B Preferred specified in the Redemption Request and calling upon such
holder to surrender to the Corporation, in the manner and at the place
designated, such holder's certificate or certificates representing the shares to
be redeemed (the "Redemption Notice"). On or after the Redemption Date, each
holder of Series B Preferred to be redeemed shall surrender to this Corporation
the certificate or certificates representing such shares, in the manner and at
the place designated in the Redemption Notice, and thereupon the Redemption
Price of such shares shall be payable to the order of the person whose name
appears on such certificate or certificates as the owner thereof and each
surrendered certificate shall be canceled. In the event less than all the shares
represented by any such certificate are redeemed, a new certificate shall be
issued representing the unredeemed shares.


                                       -3-
<PAGE>

            (c) From and after the Redemption Date, unless there shall have been
a default in payment of the Redemption Price, all rights of the holders of
shares of Series B Preferred designated for redemption in the Redemption Request
as holders of Series B Preferred (except the right to receive the Redemption
Price without interest upon surrender of their certificate or certificates)
shall cease with respect to such shares, and such shares shall not thereafter be
transferred on the books of the Corporation or be deemed to be outstanding for
any purpose whatsoever. If the funds of the Corporation legally available for
redemption of shares of Series B Preferred on the Redemption Date are
insufficient to redeem the total number of shares of Series B Preferred to be
redeemed on such date, those funds which are legally available will be used to
redeem the maximum possible number of such shares ratably among the holders of
such shares to be redeemed based upon their holdings of Series B Preferred. The
shares of Series B Preferred not redeemed shall remain outstanding and entitled
to all the rights and preferences provided herein. At any time thereafter when
additional funds of the Corporation are legally available for the redemption of
shares of Series B Preferred such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obliged to redeem on any
Redemption Date, but which it has not redeemed.

      Section 4. Conversion. The holders of the Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

            (a) Right to Convert. Each share of the Preferred Stock shall be
convertible, at the option of the holder thereof, at any time after the date of
issuance of such share, at the office of the Corporation or any transfer agent
for the Preferred Stock, into such number of fully paid and non-assessable
shares of Common Stock, in the case of the Series A Preferred, as is determined
by dividing $1,000 by the then applicable Series A Conversion Price, and in the
case of the Series B Preferred, as is determined by dividing $148.78 by the then
applicable Series B Conversion Price, determined as hereinafter provided, in
effect at the time of conversion. The price at which shares of Common Stock
shall be deliverable upon conversion of the Series A Preferred (the "Series A
Conversion Price") shall initially be $25 per share of Common Stock and the
price at which shares of Common Stock shall be deliverable upon conversion of
the Series B Preferred (the "Series B Conversion Price") shall initially be
$148.78 per share of Common Stock. Such initial Series A Conversion Price and
Series B Conversion Price shall be subject to adjustment as hereinafter
provided.

            (b) Automatic Conversion. Each share of the Preferred Stock shall
automatically be converted into shares of Common Stock at the then effective
Series A Conversion Price or Series B Conversion Price, as applicable,
immediately prior to the closing of a firm commitment underwritten public
offering pursuant to an effective registration statement on Form S-1 (or any
successor form) under the Securities Act of 1933, as amended, covering the offer
and sale of Common Stock for the account of the Corporation to the public at a
price per share (determined without regard to underwriter commissions and
expenses) of not less than Five Hundred Dollars $500.00 (as adjusted for stock
splits, stock dividends, recapitalizations and the like) and aggregate gross
proceeds to the Corporation of not less than Ten Million Dollars ($10,000,000),
before deduction of underwriting discounts and commissions and registration
expenses. In the event of such an offering, the person(s) entitled to receive
the Common Stock issuable upon such conversion of the Preferred Stock shall not
be deemed to have converted such Preferred Stock until immediately prior to the
closing of such underwritten public offering.


                                       -4-
<PAGE>

            (c) Mechanics of Conversion. No fractional shares of Common Stock
shall be issued upon conversion of the Preferred Stock. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall (after aggregating all shares into which shares of Preferred
Stock held by each holder could be converted) pay cash equal to such fraction
multiplied by the Series A Conversion Price or Series B Conversion Price, as
applicable, then in effect. Before any holder of Preferred Stock shall be
entitled to convert the same into full shares of Common Stock and to receive
certificates therefor, the holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent, and shall give written notice to the Corporation at such office
that the holder elects to convert all or any number of shares of the Preferred
Stock represented by such certificate or certificates; provided, however, that
in the event of an automatic conversion pursuant to Section 3(b), the
outstanding shares of Preferred Stock shall be converted automatically without
any further action by the holders of such shares and whether or not the
certificates representing such shares are surrendered to the Corporation or its
transfer agent, and provided further, that the Corporation shall not be
obligated to issue certificates evidencing the shares of Common Stock issuable
upon such automatic conversion unless the certificates evidencing such shares of
Preferred Stock are either delivered to the Corporation or its transfer agent as
provided above, or the holder notifies the Corporation or its transfer agent
that such certificates have been lost, stolen or destroyed and executes an
agreement satisfactory to the Corporation to indemnify the Corporation from any
loss incurred by it in connection with such certificates. The Corporation shall,
as soon as practicable after such delivery, or such agreement and
indemnification in the case of a lost certificate, issue and deliver at the
office of the Corporation or of any transfer agent, as the case may be, to such
holder of Preferred Stock, a certificate or certificates for the number of
shares of Common Stock to which the holder shall be entitled as aforesaid and a
check payable to the holder in the amount of any cash amounts payable as the
result of a conversion into a fractional share of Common Stock. Such conversion
shall not terminate the rights of the holders of the Preferred Stock or Common
Stock issuable upon conversion of the Preferred Stock to receive dividends which
have been declared with respect to the Preferred Stock prior to the date of
conversion. Except as provided in Section 4(b) above, such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Preferred Stock to be converted, or in the
case of automatic conversion immediately prior to the close of business on the
date of closing of the offering, and the person or persons entitled to receive
the shares of Common Stock issuable upon such conversion shall be treated for
all purposes as the record holder or holders of such shares of Common Stock at
the close of business on such date. If the conversion is in connection with a
firm commitment underwritten public offering of securities registered pursuant
to the Securities Act, the conversion may, at the option of any holder tendering
the Preferred Stock for conversion, be conditioned upon the closing with the
underwriter of the sale of securities pursuant so such offering, in which event
the person(s) entitled to receive the Common Stock issuable upon such conversion
of the Preferred Stock shall not be deemed to have converted such Preferred
Stock until immediately prior to the closing of such sale of securities.

            (d) Series B Preferred Conversion Price Adjustments. The Series B
Conversion Price shall be subject to adjustment from time to time as follows:

                  (i) Special Definitions. For purposes of this Section 4(d),
the following definitions shall apply:

                        (1) "Options" shall mean rights, options or warrants to
subscribe for, purchase or otherwise acquire either Common Stock or Convertible
Securities.


                                       -5-
<PAGE>

                        (2) "Series B Original Issue Date" shall mean the date
on which the first share of Series B Preferred was first issued.

                        (3) "Convertible Securities" shall mean any evidences of
indebtedness, shares (other than Common Stock and Preferred Stock) or other
securities convertible into or exchangeable for Common Stock.

                        (4) "Additional Shares of Common Stock" shall mean all
shares of Common Stock issued (or, pursuant to Section 4(d)(iii) below, deemed
to be issued) by the Corporation after the Series B Original Issue Date other
than shares of Common Stock issued or issuable:

                              (A) upon conversion of shares of the Preferred
Stock or the exercise or conversion of any Options outstanding on the Series B
Original Issue Date;

                              (B) to officers, directors, employees and
consultants of the Corporation or any subsidiary thereof, pursuant to a stock
option plan, stock purchase plan or other employee stock incentive plan approved
by the Board of Directors or other stock arrangements which have been approved
by the Board of Directors;

                              (C) pursuant to any event for which adjustment has
already been made pursuant to this Section 4(d);

                              (D) as a dividend or distribution on the Preferred
Stock;

                              (E) as a dividend or distribution on the Common
Stock;

                              (F) upon any subdivision or split up of Common
Stock; or

                              (G) upon any capital reorganization of the
Corporation.

                  (ii) No Adjustment of Conversion Price. No adjustment in the
Series B Conversion Price shall be made in respect of the issuance of Additional
Shares of Common Stock unless the consideration per share for an Additional
Share of Common Stock issued or deemed to be issued by the Corporation is less
than the Series B Conversion Price, in effect on the date of and immediately
prior to such issue.

                  (iii) Deemed Issue of Additional Shares of Common Stock.
Except as provided in Section 4(d)(i)(4) above, in the event the Corporation at
any time or from time to time after the Series B Original Issue Date shall issue
any Options or Convertible Securities or shall fix a record date for the
determination of holders of any class of securities entitled to receive any such
Options or Convertible Securities, then the maximum number of shares (as set
forth in the instrument relating thereto without regard to any provisions
contained therein for a subsequent adjustment of such number) of Common Stock
issuable upon the exercise of such Options or, in the case of Convertible
Securities and Options therefor, the conversion or exchange of such Convertible
Securities, shall be deemed to be Additional Shares of Common Stock issued as of
the time of such issue or, in case such a record date shall have been fixed, as
of the close of business on such record date, provided that Additional Shares of
Common Stock shall not be deemed to have been issued unless the consideration
per share (determined


                                       -6-
<PAGE>

pursuant to Section 4(d)(v) below) of such Additional Shares of Common Stock
would be less than the Series B Conversion Price in effect on the date of and
immediately prior to such issue, or such record date, as the case may be, and
provided further that in any such case in which Additional Shares of Common are
deemed to be issued:

                        (1) no further adjustment in the Series B Conversion
Price shall be made upon the subsequent issue of Convertible Securities or
shares of Common Stock upon the exercise of such Options or conversion or
exchange of such Convertible Securities;

                        (2) if such Options or Convertible Securities by their
terms provide, with the passage of time or otherwise, for any increase or
decrease in the consideration payable to the Corporation, or increase or
decrease in the number of shares of Common Stock issuable, upon the exercise,
conversion or exchange thereof, the Series B Conversion Price computed upon the
initial conversion prices thereof set forth in Section 4(a) above (or upon the
occurrence of a record date with respect thereto), and any subsequent
adjustments based thereon, shall, upon any such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease insofar as it
affects such Options or the rights of conversion or exchange under such
Convertible Securities;

                        (3) on the expiration or cancellation of any Options or
the termination of the right to convert or exchange any Convertible Securities
which shall have not been exercised, if the Series B Conversion Price shall have
been adjusted upon the original issuance thereof or shall have been subsequently
adjusted pursuant to clause (2) above, the Series B Conversion Price shall be
recomputed as if the only Additional Shares of Common Stock issued were shares
of Common Stock, if any, actually issued upon the exercise of such Options or
the conversion or exchange of such Convertible Securities and the consideration
received therefore was the consideration actually received by the Corporation
for the issue of all such Options, whether or not exercised, plus the
consideration actually received by the Corporation upon such exercise, or for
the issue of all such Convertible Securities which were actually converted or
exchanged plus the consideration actually received by the Corporation upon such
conversion or exchange, if any; and

                        (4) no readjustment pursuant to clause (2) or clause (3)
above shall have the effect of increasing the Series B Conversion Price to an
amount which exceeds the lower of (i) the initial Series B Conversion Price on
the original adjustment date (unless the Series B Conversion Price is increased
above the initial Series B Conversion Price pursuant to Section 4(e)(2) or
(e)(4)), or (ii) the Series B Conversion Price that would have resulted from any
issuances of Additional Shares of Common Stock (other than those the subject of
such adjustments) between the original adjustment date and such readjustment
date; and

                  (iv) Adjustment of Series B Conversion Price Upon Issuance of
Additional Shares of Common Stock. In the event this Corporation shall issue
Additional Shares of Common Stock (including Additional Shares of Common Stock
deemed to be issued pursuant to Section 4(d)(iii), but excluding stock
dividends, subdivisions or split-ups that are the subject of adjustment pursuant
to Section 4(c)) without consideration or for a consideration per share less
than the Series B Conversion Price applicable on and immediately prior to such
issue, then and in such event, the Series B Conversion Price shall be reduced,
concurrently with such issue, to a price (calculated to the nearest cent)
determined by multiplying the Series B Conversion Price in effect on the date of
and immediately prior to such issue by a fraction, the numerator of which shall
be the sum of (i) the number of shares of Common Stock


                                       -7-
<PAGE>

outstanding immediately prior to such issue (on a fully diluted as converted
basis), including without limitation the number of shares of Common Stock
issuable upon conversion of the Preferred Stock outstanding immediately prior to
such issue and (ii) the number of shares of Common Stock which the aggregate
consideration received by the Corporation for the total number of Additional
Shares of Common Stock so issued would purchase at the Series B Conversion Price
in effect on the date of and immediately prior to such issue; and the
denominator of which shall be the sum of (i) the number of shares of Common
Stock outstanding immediately prior to such issue (on a fully diluted as
converted basis), including without limitation the number of shares of Common
Stock issuable upon conversion of the Preferred Stock outstanding immediately
prior to such issue and (ii) the number of such Additional Shares of Common
Stock so issued.

                  (v) Determination of Consideration. For purposes of this
Section 4(d), the consideration received by the Corporation for the issue of any
Additional Shares of Common Stock shall be computed as follows:

                        (1) Cash and Property. Such consideration shall:

                              (A) insofar as it consists of cash, be computed at
the aggregate amount of cash received by the Corporation;

                              (B) insofar as it consists of property other than
cash, be computed at the fair value thereof at the time of such issue, as
determined in good faith by the Board of Directors; and

                              (C) in the event Additional Shares of Common Stock
are issued together with other shares or securities or other assets of the
Corporation for consideration which covers both, be the proportion of such
consideration so received, computed as provided in clauses (A) and (B) above, as
determined in good faith by the Board of Directors.

                        (2) Options and Convertible Securities. The
consideration per share received by the Corporation for Additional Shares of
Common Stock deemed to have been issued pursuant to Section 4(d)(ii) and
4(d)(iii), relating to Options and Convertible Securities, shall be determined
by dividing

                              (A) the total amount, if any, received or
receivable by the Corporation as consideration for the issue of such Options or
Convertible Securities, plus the minimum aggregate amount of additional
consideration (as set forth in the instruments relating thereto, without regard
to any provision contained therein for a subsequent adjustment of such
consideration) payable to the Corporation upon the exercise of such Options or
the conversion or exchange of such Convertible Securities, or in the case of
Options for Convertible Securities, the exercise of such options for Convertible
Securities and the conversion or exchange of such Convertible Securities by

                              (B) the maximum number of shares of Common Stock
(as set forth in the instruments relating thereto, without regard to any
provision contained therein for a subsequent adjustment of such number) issuable
upon the exercise of such Options or the conversion or exchange of such
Convertible Securities.


                                       -8-

            (e) Adjustment of Conversion Price of Both Series A Preferred and
Series B Preferred. The Series A Conversion Price and the Series B Conversion
Price shall be subject to adjustment from time to time as follows:

                  (1) Adjustments for Subdivisions of Common Stock. If the
number of shares of Common Stock outstanding at any time after filing this
Restated Certificate of Incorporation with the Secretary of State of the State
of Delaware is increased by a stock dividend payable in shares of Common Stock
or by a subdivision or split up of stock, then the Series A Conversion Price and
the Series B Conversion Price then in effect shall, concurrently with the
effectiveness of such dividend, subdivision or split up, be proportionately
decreased so that the number of shares of Common Stock issuable on conversion of
each share of Preferred Stock shall be increased in proportion to such increase
of outstanding shares of Common Stock.

                  (2) Adjustments for Combinations of Common Stock. If the
number of shares of Common stock outstanding at any time after filing this
Restated Certificate of Incorporation with the Secretary of State of the State
of Delaware is decreased by a combination of the outstanding shares of Common
Stock, then the Series A Conversion Price and the Series B Conversion Price then
in effect shall, concurrently with the effectiveness of such combination, be
proportionately increased so that the number of shares of Common Stock issuable
upon conversion of each share of such Preferred Stock shall be decreased in
proportion to such decrease in outstanding shares of Common Stock.

                  (3) Adjustments for Stock Dividends and Other Distributions.
In the event the Corporation at any time or from time to time makes, or fixes a
record date for the determination of holders of Common Stock entitled to receive
any distribution (excluding any repurchases of securities by the Corporation not
made on a pro rata basis from all holders of any class of the Corporation's
securities) payable in property or in securities of the Corporation other than
shares of Common Stock, then and in each such event the holders of Preferred
Stock shall receive at the time of such distribution, the amount of property or
the number of securities of the Corporation that they would have received had
their Preferred Stock been converted into Common Stock on the date of such
event.

                  (4) Adjustments for Reclassification, Exchange and
Substitution. Except as provided in Section 2 upon any liquidation, dissolution
or winding up of the Corporation, if the Common Stock issuable upon conversion
of the Preferred Stock shall be changed into the same or a different number of
shares of any other class or classes of stock, whether by capital
reorganization, reclassification or otherwise (other than a subdivision or
combination of shares provided for above), each share of Preferred Stock shall
thereafter be convertible into the number of shares of stock or other securities
or property to which a holder of the number of shares of Common Stock of the
Corporation deliverable upon conversion of such share of Preferred Stock shall
have been entitled upon such reorganization or reclassification.

            (f) No Impairment. The Corporation will not, by amendment of its
Certificate of Incorporation or By-laws or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms to be observed or performed hereunder by the Corporation but
will at all times in good faith assist in the carrying out of all the provisions
of this Section 4 and in the taking of all such action as may be necessary or
appropriate in order to protect the conversion rights of the holders of the
Preferred Stock against impairment.


                                       -9-
<PAGE>

            (g) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Series A Conversion Price or Series B
Conversion Price pursuant to this Section 4, the Corporation at its expense
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and furnish to each holder of Preferred Stock a certificate setting
forth such adjustment or readjustment and showing in detail the faces upon which
such adjustment or readjustment is based. The Corporation shall, upon the
written request at any time of any holder of Preferred Stock, furnish or cause
to be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Series A Conversion Price or the Series
B Conversion Price, as applicable, at the time in effect, and (iii) the number
of shares of Common Stock and the amount, if any, of other property which at the
time would be received upon the conversion of Preferred Stock. Notwithstanding
the foregoing, no adjustment of the Series A Conversion Price or the Series B
Conversion Price shall be made if the amount of any such adjustment would be an
amount less than $1.00, but any such amount shall be carried forward and an
adjustment with respect thereof shall be made at the time of and together with
any subsequent adjustment which, together with such amount and any other
amount(s) so carried forward, shall aggregate an increase or decrease of $1.00
or more.

            (h) Notices of Record Date. In the event that the Corporation shall
propose at any time:

                  (i) to declare any dividend or distribution upon its Common
Stock, whether in cash, property, stock or other securities, whether or not a
regular cash dividend and whether or not out of earnings or earned surplus;

                  (ii) to offer for subscription pro rata to the holders of any
class or series of its stock any additional shares of stock of any class or
series or other rights;

                  (iii) to effect any reclassification or recapitalization of
its Common Stock outstanding involving a change in the Common Stock; or

                  (iv) to merge or consolidate with or into any other
corporation, or sell, lease or convey all or substantially all its property or
business, or to liquidate, dissolve or wind up;

                        then, in connection with each such event, the
Corporation shall send to the holders of the Preferred Stock:

                        (1) at least 20 days' prior written notice of the date
on which a record shall be taken for such dividend, distribution or subscription
rights (and specifying the date on which the holders of Common Stock shall be
entitled thereto) or for determining rights to vote in respect of the matters
referred to in (iii) and (iv) above; and

                        (2) in the case of the matters referred to in (iii) and
(iv) above, at least 20 days' prior written notice of the date when the same
shall take place (and specifying the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event).


                                      -10-
<PAGE>

      Each such written notice shall be delivered personally or given by first
class mail, postage prepaid, addressed to the holders of Preferred Stock at the
address for each such holder as shown on the books of the Corporation.

                  (v) Reservation of Shares. The Corporation shall reserve at
all times so long as any shares of Preferred Stock remain outstanding, free from
preemptive rights, out of its treasure stock or its authorized but unissued
shares of Common Stock, or both, solely for the purposes of effecting the
conversion of the shares of Preferred Stock, sufficient shares of Common Stock
to provide for the conversion of all outstanding shares of Preferred Stock.

                  (vi) Valid Issuance. All shares of Common Stock which may be
issued upon conversion of the shares of Preferred Stock will upon issuance by
the Corporation be duly and validly issued, fully paid and nonassessable and
free from all taxes, liens and charges with respect to the issuance thereof and
the Corporation shall take no action which will cause a contrary result.

      Section 5. Voting Rights and Directors.

            (a) Except as otherwise provided herein or required by law, the
holder of each share of Common Stock issued and outstanding shall have one vote
with respect to such share and the holder of each share of Preferred Stock shall
be entitled with respect to such share to a number of votes equal to the number
of shares of Common Stock into which such share of Preferred Stock could be
converted at the record date for determination of the stockholders entitled to
vote on such matters, or, if no such record date is established, at the date
such vote is taken or any written consent of stockholders is solicited, such
votes to be counted together with all other shares of stock of the Company
having general voting power and not separately as a class (except as required by
Section 5(b) below, Section 6 or by the General Corporation Law of Delaware).
Holders of Common Stock and Preferred Stock shall be entitled to notice of any
stockholders' meeting in accordance with the Bylaws of the Corporation.
Fractional votes by the holders of Preferred Stock shall not, however, be
permitted and any fractional voting rights shall (after aggregating all shares
into which shares of Preferred Stock held by each holder could be converted) be
rounded to the nearest whole number.

            (b) The Board of Directors shall consist of seven (7) members. The
holders of the Series B Preferred, voting separately as a class, shall be
entitled to elect two (2) members of the Board of Directors. The holders of
Common Stock and Series A Preferred, voting together, shall be entitled to elect
the remaining members of the Board of Directors. At any meeting held for the
purpose of electing or removing directors, (i) the presence in person or by
proxy of the holders of the majority of the shares of Series B Preferred then
outstanding shall constitute a quorum of the Series B Preferred for the purpose
of electing or removing directors by holders of the Series B Preferred and (ii)
the presence in person or by proxy of the holders of a majority of shares of
Common Stock and Series A Preferred (on an as converted into Common Stock basis)
then outstanding shall constitute a quorum of Common Stock and Series A
Preferred for the purpose of electing or removing directors by holders of Common
Stock and Series A Preferred. A vacancy in any directorship elected by the
holders of the Series B Preferred shall be filled only by vote or written
consent in lieu of a meeting of the holders of the Series B Preferred. A vacancy
in any directorship elected by the holders of Common Stock and Series A
Preferred shall be filled only by vote or written consent in lieu of a meeting
of the holders of Common Stock and the Series A Preferred. Any member of the
Board of Directors elected by the holders of the Series B


                                      -11-
<PAGE>

Preferred may only be removed by the vote of the holders of not less than a
majority of the shares of Series B Preferred voting thereon. Any member of the
Board of Directors elected by the holders of Common Stock and Series A Preferred
may only be removed by the vote of the holders of not less than a majority of
the shares of Common Stock and Series A Preferred (on an as convened into Common
Stock basis) voting thereon.

            (c) At all elections of members of the Board of Directors of the
Corporation, if any holder of stock of this Corporation entitled to vote at an
election shall have given the Corporation written notice of its intention to
cumulate his or her votes for the election of members of the Board of Directors
prior to the commencement of the voting for such members, then each holder
entitled to vote for members of the Board of Directors shall be entitled to as
many votes as shall equal the number of votes which (except for this provision
as to cumulative voting) such holder would be entitled to cast for the election
of directors with respect to his or her shares of stock multiplied by the number
of directors to be elected by such holder either (i) by casting all such
holder's votes for a single director or (ii) by distributing such holder's votes
among the number of directors to be voted for, or for any two or more of them as
such holder may see fit.

      Section 6. Covenant. In addition to any other rights provided by law, so
long as any Series B Preferred shall be outstanding, the Corporation shall not,
without first obtaining the written consent of the holders of not less than a
majority of the then outstanding shares of Series B Preferred:

            (a) amend or repeal any provision of, or add any provision to, this

parity with the Series B Preferred as to dividend rights, voting rights,
redemption rights or liquidation preferences;

            (d) redeem or purchase any of the Series A Preferred or any of the
Common Stock, provided, however, that this restriction shall not apply to the
repurchase or shares of Common Stock from employees, officers, directors,
consultants or other persons performing services for the Corporation upon or
after termination of the employment, consulting or other relationship between
the Corporation and such persons; provided, further, that such repurchase is not
made at a price greater than the original purchase price of such shares pursuant
to vesting or similar provisions;

            (e) authorize or issue options or warrants to purchase in excess of
4,000 shares of Common Stock (appropriately adjusted for stock splits, stock

shares of Common Stock (appropriately adjusted for stock splits, stock dividends
and recapitalizations) to officers, directors, employees and consultants of the

            (j) authorize a merger, consolidation, recapitalization or
reorganization of CVC Products, Inc., or authorize the sale of all or

            (k) declare or pay any dividend or other distribution on the Common
Stock or any series of Preferred Stock other than the Series B Preferred.

      Section 7. No Reissuance of Series B Preferred. No share or shares of
Series B Preferred acquired by the Corporation by reason of redemption,
purchase, conversion or otherwise shall be reissued, and all such shares should
be canceled, returned and eliminated from the shares which the Corporation shall
be authorized to issue.

the Board of Directors.

                                   Article VI

dissolution or of any receiver or receivers appointed for the Corporation under
the provisions of Section 279 of Title 8 of the Delaware Code order a meeting of

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

                                    ARTICLE I

                                    STOCK AND
                                  STOCKHOLDERS

            1. CERTIFICATES REPRESENTING STOCK. Every holder of stock in the
corporation shall be entitled to have a certificate signed by, or in the name
of, the corporation by the President or a Vice-President and by the Treasurer or
an Assistant Treasurer or the Secretary or an Assistant Secretary of the
corporation certifying the number of shares owned by him in the corporation. Any
and all signatures on any such certificate may be facsimiles. In case any
officer, transfer agent or registrar who has signed or whose facsimile signature
has been placed upon a certificate shall have ceased to be such officer,
transfer agent or registrar before such certificate is issued, it may be issued
by the corporation with the same effect as if he were such officer, transfer
agent or registrar at the date of issue.

            Whenever the corporation shall be authorized to issue more than one
class of stock or more than one series of any class stock, and whenever the
corporation shall issue any shares of its stock as partly paid stock, the
certificate representing shares of any such class or series or of any such
partly paid stock shall set forth thereon the statements prescribed by the
General Corporation Law. Any restrictions on the transfer or registration of
transfer of any shares of stock of any class or series shall be noted
conspicuously on the certificate representing such shares.

            The corporation may issue a new certificate of stock in place of any
certificate theretofore issued by it, alleged to have been lost, stolen, or
destroyed, and the Board of Directors may require the owner of any lost, stolen,
or destroyed certificate or his legal representative, to give the corporation a
bond sufficient to indemnify the corporation against any claim
<PAGE>

that may be made against it on account of the alleged loss, theft, or
destruction of any such certificate or the issuance of any such new certificate.

            2. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be
required to, issue fractions of a share of stock. If the corporation does not
issue fractions of a share, it shall (1) arrange for the disposition of
fractional interests by those entitled thereto, (2) pay in cash the fair value
of fractions of a share of stock as of the time when those entitled to receive
such fractions are determined, (3) issue scrip or warrants in registered or
bearer form which shall entitle the holder to receive a certificate for a full
share upon the surrender of such scrip or warrants aggregating a full share. A
certificate for a fractional share shall, but such scrip or warrants shall not
unless provided therein, entitle the holder to exercise voting rights, to
receive dividends thereon, and to participate in any of the assets of the
corporation in the event of liquidation. The Board of Directors may cause scrip
or warrants to be issued subject to the condition that they shall become void if
not exchanged for certificates representing full shares of stock before a
specified date, or subject to the condition that the shares of stock for which
scrip or warrants are exchangeable may be sold by the corporation and the
proceeds thereof distributed to the holders of scrip or warrants, or subject to
any other conditions which the Board of Directors may determine.

            3. STOCK TRANSFERS. Upon compliance with provisions restricting the
transfer or registration of transfer of shares of stock, if any, transfers or
registration of transfers of shares of stock of the corporation shall be made
only on the stock ledger of the corporation by the registered holder thereof, or
by his attorney thereunder authorized by power of attorney duly executed and
filed with the Secretary of the corporation or with a transfer agent or a
registrar, if any, and on surrender of the certificate or certificates for such
shares of stock properly endorsed and the payment of all taxes due thereon.

            4. RECORD DATE FOR STOCKHOLDERS. For the purpose of determining the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to or dissent from any corporate
action in writing without a meeting, or entitled to receive payment of any
dividend or other distribution or the allotment of any rights, or entitled to
exercise any rights in respect of any change, conversion, or exchange of stock,
or for the purpose of any other lawful action, the directors may fix, in
advance, a date as the record date for any such determination of stockholders.
Such date shall not be more than sixty days nor less than ten days


                                      -2-
<PAGE>

before the date of such meeting, nor more than sixty days prior to any other
action. If no record date is fixed, the record date for the determination of
stockholders entitled to notice of or to vote at a meeting of stockholders shall
be at the close of business on the day next preceding the day on which notice is
given, or, if notice is waived, at the close of business on the day next
preceding the day on which the meeting is held; the record date for determining
stockholders entitled to express consent to corporate action in writing without
a meeting, when no prior action by the Board of Directors is necessary, shall be
the day on which the first written consent is expressed; and the record date for
determining stockholders for any other purpose shall be at the close of business
on the day on which the Board of Directors adopts the resolution relating
thereto. When a determination of stockholders of record entitled to notice of or
to vote at any meeting of stockholders has been made as provided in this
paragraph, such determination shall apply to any adjournment thereof; provided,
however, that the Board of Directors may fix a new record date for the adjourned
meeting.

            5. STOCKHOLDER MEETINGS.

            - TIME. The annual meeting shall be held on the date and at the time
fixed from time to time by the Board of Directors, provided, that the first
annual meeting shall be held on a date within thirteen months after the
organization of the corporation, and each successive annual meeting shall be
held on a date within thirteen months after the date of the preceding annual
meeting. A special meeting shall be held on the date and at the time fixed by
the Board of Directors.

            - PLACE. Annual meetings and special meetings shall be held at such
place, within or without the State of Delaware, as the Board of Directors may
from time to time fix. Whenever the Board of Directors shall fail to fix such
place, the meeting shall be held at the principal executive office of the
corporation.

            - CALL. Annual meetings and special meetings may be called by the
Board of Directors, the President, or any two or more directors, and shall be
called by the President or a Vice President or the Secretary at the written
demand of the holders of at least one-fourth of all outstanding shares
entitled to vote on the action proposed to be taken at such meeting, which
demand shall state the purpose or purposes of the proposed meeting.

            - NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall
be given, stating the place, date, and hour of the meeting and stating the place
within the city or other municipality or community at which the list of
stockholders of


                                      -3-
<PAGE>

the corporation may be examined. The notice of an annual meeting shall state
that the meeting is called for the election of directors and for the transaction
of other business which may properly come before the meeting, and shall (if any
other action which could be taken at a special meeting is to be taken at such
annual meeting) state the purpose or purposes. The notice of a special meeting
shall in all instances state the purpose or purposes for which the meeting is
called. The notice of any meeting shall also include, or be accompanied by, any
additional statements, information or documents prescribed by the General
Corporation Law. Except as otherwise provided by the General Corporation Law, a
copy of the notice of any meeting shall be given, personally or by mail, not
less than ten days nor more than sixty days before the date of the meeting,
unless the lapse of the prescribed period of time shall have been waived, and
directed to each stockholder at his record address or at such other address
which he may have furnished by request in writing to the Secretary of the
corporation. Notice by mail shall be deemed to be given when deposited, with
postage thereon prepaid, in the United States mail. If a meeting is adjourned to
another time, not more than thirty days hence, and/or to another place, and if
an announcement of the adjourned time and place is made at the meeting, it shall
not be necessary to give notice of the adjourned meeting unless the directors,
after adjournment, fix a new record date for the adjourned meeting. Notice need
not be given to any stockholder who submits a written waiver of notice signed
by him before or after the time stated therein. Attendance of a person at a
meeting of stockholders shall constitute a waiver of notice of such meeting,
except when the stockholder attends a meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened. Neither the business to
be transacted at, nor the purpose of, any regular or special meeting of the
stockholders need be specified in any written waiver of notice.

            - STOCKHOLDER LIST. The officer who has charge of the stock ledger
of the corporation shall prepare and make, at least ten days before every
meeting of stockholders, a complete list of the stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city or other
municipality or community where the meeting is to be held, which place shall be
specified in the notice of the meeting, or if not so specified, at the place
where the meeting is to be held. The list shall also be produced and kept at the
time and place of the


                                      -4-
<PAGE>

meeting during the whole time thereof, and may be inspected by any stockholder
who is present. The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by this
section or the books of the corporation, or to vote in person or by proxy at any
meeting of stockholders.

            - CONDUCT OF MEETING. Meetings of the stockholders shall be presided
over by one of the following officers in the order of seniority and if present
and acting - the President, a Vice-President, or, if none of the foregoing is
in office and present and acting, by a chairman to be chosen by the
stockholders. The Secretary of the corporation, or in his absence, an Assistant
Secretary, shall act as secretary of every meeting, but if neither the Secretary
nor an Assistant Secretary is present the chairman of the meeting shall appoint
a secretary of the meeting.

            - PROXY REPRESENTATION. Each stockholder entitled to vote at a
meeting of stockholders, or to express consent or dissent to corporate action
without a meeting, may authorize another person or persons to act for him by
proxy. Every proxy must be signed by the stockholder or by his attorney-in-fact.
No proxy shall be voted or acted upon after three years from its date unless
such proxy provides for a longer period. A duly executed proxy shall be
irrevocable if it states that it is irrevocable and, if, and only as long as, it
is coupled with an interest sufficient in law to support an irrevocable power. A
proxy may be made irrevocable regardless of whether the interest with which it
is coupled is an interest in the stock itself or an interest in the corporation
generally.

            - INSPECTORS AND JUDGES. The Board of Directors, in advance of any
meeting, may, but need not, appoint one or more inspectors of election or judges
of the vote, as the case may be, to act at the meeting or any adjournment
thereof. If an inspector or inspectors or judge or judges are not appointed, the
person presiding at the meeting may, but need not, appoint one or more
inspectors or judges. In case any person who may be appointed as an inspector or
judge fails to appear or act, the vacancy may be filled by appointment made by
the directors in advance of the meeting or at the meeting by the person
presiding thereat. Each inspector or judge, if any, before entering upon the
discharge of his duties, shall take and sign an oath faithfully to execute the
duties of inspector or judge at such meeting with strict impartiality and
according to the best of his ability. The inspectors or judges, if any, shall
determine the number of shares of stock outstanding and the voting power of
each, the shares of stock represented at the meeting, the existence of a quorum
and the validity and effect of proxies, and


                                      -5-
<PAGE>

shall receive votes, ballots or consents, hear and determine all challenges and
questions arising in connection with the right to vote, count and tabulate all
votes, ballots or consents, determine the result, and do such acts as are proper
to conduct the election or vote with fairness to all stockholders. On request of
the person presiding at the meeting, the inspector or inspectors or judge or
judges, if any, shall make a report in writing of any challenge, question or
matter determined by him or them and execute a certificate of any fact found by
him or them.

            - QUORUM. The holders of a majority of the outstanding shares of
stock entitled to vote, present in person or represented by proxy, shall
constitute a quorum at a meeting of stockholders for the transaction of any
business. The stockholders present may adjourn the meeting despite the absence
of a quorum.

            - VOTING. Except as otherwise provided by the General Corporation
Law or by the Certificate of Incorporation, each share of stock entitled to vote
shall entitle the holder thereof to one vote. In the election of directors, a
plurality of the votes cast shall elect. Directors shall be elected by
cumulative voting, if and as provided in the Certificate of Incorporation. Any
other action shall be authorized by a majority of the votes cast except where
the General Corporation Law or these by-laws or the Certificate of
Incorporation prescribes a different percentage of votes and/or a different
exercise of voting power. In the election of directors, voting need not be by
ballot. Voting by ballot shall not be required for any other corporate action
except as otherwise provided by the General Corporation Law.

            6. STOCKHOLDER ACTION WITHOUT A MEETING. Any action required by the
General Corporation Law to be taken or which may be taken at any annual or
special meeting of stockholders may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted. Prompt notice of the taking of the corporate action without a meeting
by less than unanimous written consent shall be given to those stockholders who
have not consented in writing.

                                   ARTICLE II

                                    DIRECTORS

            1. FUNCTIONS AND DEFINITION. The business of the corporation shall
be managed by or under the direction of the Board of Directors of the
corporation. The use of the phrase "whole Board" herein refers to the total
number of directors which the corporation would have if there were no vacancies.

            2. QUALIFICATIONS AND NUMBER. A director need not be a stockholder,
a citizen of the United States, or a resident of the State of Delaware. The
initial Board of Directors shall consist of one person. On each subsequent Board
of Directors, the number of directors shall be no less than one, nor more than
seven, such number to be fixed from time to time by action of the stockholders
or of the directors, or, if the number is not fixed, the number shall be one.
The number of directors may be increased or decreased by action of the
stockholders or of the Board.

            3. ELECTION AND TERM. The first Board of Directors, unless the
members thereof shall have been named in the Certificate of Incorporation, shall
be elected by the incorporator or incorporators and shall hold office until the
first annual meeting of stockholders and until their successors have been
elected and qualified or until their earlier resignation or removal. Thereafter,
directors who are elected at an annual meeting of stockholders, and directors
who are elected in the interim to fill vacancies and newly created
directorships, shall hold office until the next annual meeting of stockholders
and until their successors have been elected and qualified or until their
earlier resignation or removal. In the interim between annual meetings of
stockholders or of special meetings of stockholders called for the election of
directors and/or for the removal of one or more directors and for the filling of
any vacancy in that connection, newly created directorships and any vacancies in
the Board of Directors, including vacancies resulting from the removal of
directors for cause or without cause, may be filled by the vote of a majority of
the directors then in office, although less than a quorum, or by the sole
remaining director, for the balance of the term thereof, or if the Board of
Directors has not filled any such vacancy, it may be filled by vote of the
stockholders.


                                      -7-

            4. MEETINGS.

            - TIME. Meetings shall be held at such time as the Board shall fix,
except that the first meeting of a newly elected Board shall be held as soon
after its election as the directors may conveniently assemble.

            - PLACE. Meetings shall be held at such place within or without the
State of Delaware as shall be fixed by the Board.

            - CALL. No call shall be required for regular meetings for which the
time and place have been fixed. Special meetings may be called by or at the
direction of the President, or any two (2) of the directors in office.

            - NOTICE OR ACTUAL OR CONSTRUCTIVE WAIVER. No notice shall be
required for regular meetings for which the time and place have been fixed.
Written, oral, or any other mode of notice of the time and place shall be given
for special meetings in sufficient time for the convenient assembly of the
directors thereat. The notice of any regular or special meeting shall specify
the business to be transacted at the meeting and/or the purpose or purposes for
which such meeting is being called, and no other business or purpose may be
conducted or considered at such meeting. Notice need not be given to any
director who submits a written waiver of notice signed by him before or after
the time of the meeting. Attendance of any such person at a meeting shall
constitute a waiver of notice of such meeting, except when he attends a meeting
for the sole purpose of objecting, at the beginning of the meeting, to the
transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting need be specified in any written waiver of notice.

            - QUORUM AND ACTION. A majority of the whole Board shall constitute
a quorum except when a vacancy or vacancies prevents such majority, whereupon a
majority of the directors in office shall constitute a quorum, provided, that
such majority shall constitute at least one-third of the whole Board, except
that if the number of directors constituting the whole Board is one, then one
director shall constitute a quorum. A majority of the directors present, whether
or not a quorum is present, may adjourn a meeting to another time and place.
Except as herein otherwise provided, and except as otherwise provided by the
General Corporation Law and the Certificate of Incorporation, the act of the
Board shall be the act by vote of a majority of the directors present at a
meeting at which a quorum is present.


                                      -8-

            - CHAIRMAN OF THE MEETING. The President shall preside at all
meetings. If, for any reason, the President is not present at any meeting, any
director chosen by the Board shall preside.

            5. REMOVAL OF DIRECTORS. Except as may otherwise be provided by the
General Corporation Law or the Certificate of Incorporation, any or all of the
directors may be removed for cause or without cause by the holders of a majority
of the shares then entitled to vote at an election of directors, provided,
however, that, in case of the corporation having cumulative voting, no director
may be removed without cause if the votes cast against his removal would be
sufficient to elect him if voted cumulatively at an election of directors at
which the same number of votes were cast and the whole Board were then being
elected.

            6. COMMITTEES. The Board may, by resolution passed by a majority of
the whole Board, designate one or more committees, each committee to consist of
one or more of the directors of the corporation. The Board may designate one or
more directors as alternate members of any committee who may replace any absent
or disqualified member at any meeting of the committee. Any such committee, to
the extent provided in the resolution of the Board and except as hereinafter
provided, shall have and may exercise the powers of the Board of Directors in
the management of the business and affairs of the corporation, and may authorize
the seal of the corporation to be affixed to all papers which may require it.
No such committee shall have the power or authority to amend the Certificate of
Incorporation, adopt an agreement of merger or consolidation, recommend to the
stockholders the sale, lease or exchange of all or substantially all of the
corporation's property and assets, recommend to the stockholders a dissolution
of the corporation or a revocation of a dissolution, declare a dividend,
authorize the issuance of stock, elect or remove any officer, amend or repeal
any resolution adopted by the Board or take any action prohibited by the General
Corporation Law. The notice provisions of these By-Laws pertaining to
directors' meetings shall also apply to all committee meetings.

            7. ACTION IN WRITING. Any action required or permitted to be taken
at any meeting of the Board of Directors or any committee thereof may be taken
without a meeting if all members of the Board or committee, as the case may be,
consent thereto in writing, and the writing or writings are filed with the
minutes of proceedings of the Board or committee.


                                      -9-

            8. PARTICIPATION BY CONFERENCE PHONE. Members of the Board, or any
committee designated by the Board, may participate in a meeting of the Board or
committee, as the case may be, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and participation in a meeting pursuant to this
provision shall constitute presence in person at such meeting.

            9. COMPENSATION OF DIRECTORS. The Board, by the affirmative vote of
a majority of directors in office and regardless of any personal interest of any
of them, may establish reasonable compensation of all directors and of the
President.

                                   ARTICLE III

                                    OFFICERS

Secretary, and may elect one or more Vice Presidents (including Executive,
Senior and/or Assistant Vice Presidents), a Treasurer, Assistant Secretaries,
Assistant Treasurers, and such other officers and agents as are desired. The

execute, acknowledge or verify any instrument required by the General
Corporation Law or these By-Laws to be executed, acknowledged or verified by two
or more officers.

            2. TERMS OF OFFICE. Unless otherwise provided in the resolution of

Board following the next annual meeting of stockholders and until his successor
has been elected and qualified.

            3. PRESIDENT. The President shall be the chairman of the Board of
Directors and chief executive officer of the corporation, shall preside at all
meetings of the Board and of the stockholders, and shall be a member ex officio
of all committees of the Board. The President shall also be the chief operating
officer of the corporation, and shall have general and active management,
direction and supervision over the business and affairs of the corporation and
over its several subordinate officers.

            4. VICE PRESIDENTS. Each Vice President shall have such powers and

determined by the


                                      -10-
<PAGE>

President or by the Board, or if there be no such determination, in the order of
the election of Executive Vice Presidents, then of Senior Vice Presidents, then
of Vice Presidents, and finally of Assistant Vice Presidents) may perform all
the duties and may exercise any of the powers of the President. The performance
of any such duty by a Vice President shall be conclusive evidence of his power
to act.

            5. SECRETARY. The Secretary shall have charge of the minutes of all
proceedings of the shareholders and of the Board. He shall attend to the giving
of all notices to shareholders and directors. He shall have charge of the seal

            6. TREASURER. The Treasurer shall have charge of all funds and
securities of the Corporation, shall endorse the same for deposit or collection
when necessary and shall deposit the same to the credit of the corporation in
such banks or depositaries as the President may authorize. He may endorse all
commercial documents requiring endorsements for or on behalf of the corporation
and may sign all receipts and vouchers for payments made to the corporation. He
shall have all such powers and duties as generally are incident to the position
of Treasurer or as may be assigned to him by the President or by the Board.

            7. ASSISTANT SECRETARIES. In the absence or inability of the
Secretary to act, any Assistant Secretary may perform all the duties and

assign to him.

            8. ASSISTANT TREASURERS. In the absence or inability of the
Treasurer to act, an Assistant Treasurer may perform all the duties and exercise

assign to him.

            9. REMOVAL. The Board may remove any officer for cause or without

                                   ARTICLE IV

                                INDEMNIFICATION

            1. LIMITATION OF CERTAIN LIABILITY OF DIRECTORS. To the fullest
extent permitted by the Delaware General Corporation Law as the same exists or
may hereafter be amended, a director of the corporation shall not be liable to
the corporation or its stockholders for monetary damages for breach of fiduciary
duty as director.

            2. INDEMNIFICATION AND INSURANCE. (a) Each person who was or is made
a party or is threatened to be made a party to or is involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "Proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer
of the corporation or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged action
in an official capacity as a director, officer, employee or agent or in any
other capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by the corporation to the fullest extent
authorized by the Delaware General Corporation Law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits the corporation to provide broader indemnification
rights than said law permitted the corporation to provide prior to such
amendment), against all expense, liability and loss (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid
in settlement) reasonably incurred or suffered by such person in connection
therewith and such indemnification shall continue as to a person who has ceased
to be a director, officer, employee or agent and shall inure to the benefit of
his or her heirs, executors and administrators; provided, however, that, except
as provided in paragraph (b) hereof, the corporation shall indemnify any such
person seeking indemnification in connection with a proceeding (or part thereof)
initiated by such person only if such proceeding (or part thereof) was
authorized by the Board of Directors of the corporation. The right to
indemnification conferred in this Section 2 shall be a contract right and shall
include the right to be paid by the corporation the expenses incurred in
defending any such proceeding in advance of its final


                                      -12-
<PAGE>

disposition; provided, however, that if the Delaware General Corporation Law
requires, the payment of such expenses incurred by a director or officer in his
or her capacity as a director or officer (and not in any other capacity in which
service was or is rendered by such person while a director or officer, including
without limitation service to an employee benefit plan) in advance of the final
disposition of a proceeding shall be made only upon delivery to the corporation
of an undertaking, by or on behalf of such director or officer, to repay all
amounts so advanced if it shall ultimately be determined that such director or
officer is not entitled to be indemnified under this Section 2 or otherwise. The
corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of the corporation with the same scope and effect as the
foregoing indemnification of directors and officers.

                  (b) If a claim under paragraph (a) of this Section 2 is not
paid in full by the corporation within ninety days after a written claim has
been received by the corporation, the claimant may at any time thereafter bring
suit against the corporation to recover the unpaid amount of the claim and, if
successful in whole or in part, the claimant shall be entitled to be paid also
the expense of prosecuting such claim. It shall be a defense to any such action
(other than an action brought to enforce a claim for expenses incurred in
defending any proceeding in advance of its final disposition where the required
undertaking, if any is required, has been tendered to the corporation) that the
claimant has not met the standards of conduct which make it permissible under
the Delaware General Corporation Law for the corporation to indemnify the
claimant for the amount claimed, but the burden of proving such defense shall be
on the corporation. Neither the failure of the corporation (including its Board
of Directors, independent legal counsel, or its stockholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in the Delaware General Corporation
Law, nor an actual determination by the corporation (including its Board of
Directors independent legal counsel, or its stockholders) that the claimant has
not met such applicable standard of conduct, shall be a defense to the action or
create a presumption that the claimant has not met the applicable standard of
conduct.

            3. NON-EXCLUSIVITY OF RIGHTS. The right to indemnification and the
payment of expenses conferred in this Article shall not be deemed exclusive of
any other right to which any person seeking indemnification or payment of
expenses may be entitled under any statute, provision of the Certificate of
Incorporation by-law, agreement, vote of stockholders or


                                      -13-
<PAGE>

disinterested directors or otherwise, both as to action in such person's
official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

            4. INSURANCE. The corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the Delaware General Corporation Law.

                                    ARTICLE V

                  CONTRACTS, LOANS, CHECKS, NOTES, DRAFTS, ETC.

            Contracts, checks, notes, drafts, acceptances, bills of exchange and
other instruments, orders or obligations for the payment of money shall be
signed by the President or by such officer or officers or person or persons as
the Board or the President shall from time to time determine.

                                   ARTICLE VI

                                 CORPORATE SEAL

            The corporate seal shall be in such form as the Board shall
prescribe.

                                   ARTICLE VII

                                   FISCAL YEAR

            The fiscal year of the corporation shall be fixed, and shall be
subject to change, by the Board.

                                   AMENDMENTS

            The Board of Directors shall have the power to make, alter or repeal
the By-Laws of the corporation subject to the power of the stockholders to
alter or repeal the By-Laws made or altered by the Board of Directors. The
stockholders shall also have the power to make, alter or repeal the By-Laws of
the corporation.

CVC HOLDINGS, INC. BYLAW AMENDMENTS

(approved by Unanimous Consent of
the Board of Directors of CVC
Holdings, Inc. (the "Corporation"),
dated May 11, 1995)

            Article II, Section 3 of the Bylaws of the Corporation were amended
by deleting the last sentence of such section and substituting the following
therefor:

            "In the interim between annual meetings of stockholders or of
            special meetings of stockholders called for the election of
            directors and/or for the removal of one or more of the directors and
            for the filling of any vacancy in that connection, newly created
            directorships and any vacancies in the Board of Directors, including
            vacancies resulting from the removal of directors for cause or
            without casue, may be filled only by the vote or written consent in
            lieu of meeting of the class of stockholders entitled to elect such
            director. At any meeting held for the purpose of electing a director
            or directors, the presence in person or by proxy of the holders of
            the majority of shares then outstanding of the class entitled to
            vote for the election of such director or directors shall constitute
            a quorum for the purpose of electing a director or directors by the
            stockholders of such class."

            Article II, Section 5 of the Bylaws of the Corporation were amended
by deleting such section in its entirety and substituting the following
therefor:

            "5. Removal of Directors. Except as may otherwise be provided by the
            General Corporation Law or the Certificate of Incorporation, any or
            all of the directors elected by a class of stockholders may only be
            removed by the vote of the holders of not less than a majority of
            the shares of such class voting thereon, provided, however, that in
            case of the corporation having cumulative voting, no director may be
            removed without cause if the votes against his removal would be
            sufficient to elect him if voted cumulatively at an election of
            directors at which the same number of votes were cast and the whole
            Board were then being elected. At any meeting held for the purpose
            of removing a director or directors, the presence in person or by
            proxy of the holders of the majority of shares then outstanding of
            the class entitled to vote for the removal of such director or
            directors shall constitute a quorum for the purpose of removing a
            director or directors by the stockholders of such class."

Corporation owned by him, signed by, or in the name of, the Corporation by the
Chairman of the Board or the President or a Vice President and by the Treasurer
or an Assistant Treasurer or the Secretary or an Assistant Secretary of the
Corporation. Any of or all of the signatures on the certificate may be a
facsimile. In case any officer, transfer agent or registrar who has signed or
whose facsimile signature has been placed upon a certificate shall have ceased

issued, it may be issued by the Corporation with the same effect as if he were
such officer, transfer agent or registrar.

            Section 2. Transfers: Certificates shall be registered for transfer
on the stock books of the Corporation in person or by attorney, but, except as
hereinafter provided in the case of loss, destruction or mutilation of

<PAGE>
                                     - 10 -

Directors or the Executive Committee of the Corporation may require the owner of
the lost, stolen or destroyed certificate, or his legal representative, to give
the Corporation a bond of indemnity, in form and with one or more sureties
satisfactory to the Board or the Executive Committee, sufficient to indemnify it
against any claim that may be made against the Corporation on account of the
alleged loss, theft or destruction of any such certificate or the issuance of
such new certificate.

            Section 4. Record Date: The Board of Directors may fix, in advance,
a date, which shall not be more than sixty (60) nor less than ten (10) days

entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or allotment of any rights, or entitled to exercise any rights with
respect to any change, conversion or exchange of stock or for the purpose of any
other lawful action. If no record date is fixed, (a) the record date for

business on the day on which the Board of Directors adopts the resolutions

a circle and shall bear the name of the Corporation, the year of incorporation,
and any other matters deemed appropriate by the Board of Directors.

            Section 2. Indemnification. Every person heretofore, now, or
hereafter serving as a director, officer or employee of the Corporation, and
every person heretofore, now, or thereafter serving at the written request of
the Corporation (or at its oral request subsequently confined in writing) as a
director, officer or employee of another corporation or other business
association in which the Corporation owns shares of capital stock or other
proprietary interest or of which the Corporation is a creditor, shall be
indemnified and held harmless by the Corporation from and against any and all
loss, cost, liability and expense that may be imposed upon or incurred by him in
connection with or resulting from any claim, action, suit or proceeding, whether
civil, criminal, administrative or investigative in which he may become involved
as a party or otherwise by reason of his being or having been a director,
officer or employee of the Corporation, or of another business association or
corporation in which the Corporation owns shares of capital stock or other
proprietary interest or of which the Corporation is a creditor, whether or not
he continues to be such at the time such loss, cost liability or expense shall
have been imposed or incurred. As used herein, the term "loss, cost, liability
and expense" shall include all expenses incurred in the defense of such claim,
action, suit or proceeding and the amounts of judgments, fines, or penalties
levied or rendered against any such person; provided, however, that no such
person shall be entitled to indemnity hereunder unless the Board of Directors of
the Corporation determines that such person was acting in good faith and for a
purpose which he reasonably believed to be in or not opposed to the best
interests or the Corporation, and with respect to any criminal action or
porceeding had no reasonable cause to believe his conduct was unlawful. Payments
authorized hereunder include amounts paid and expenses incurred in settling any
such claim, action, suit or proceeding whether actually commenced or threatened.
Expenses incurred with respect to any such

<PAGE>
                                     - 12 -


claim, action, suit or proceeding may be advanced by the Corporation prior to
the final disposition thereof upon receipt of an undertaking satisfactory in
from and amount to the Board of Directors by or on behalf of the recipient to
repay such amount unless it is ultimately determined that he is entitled to
indemnification. The foregoing right of indemnification shall not be deemed
exclusive of any other rights to which those seeking indemnification may be
entitled under any law, by-law, provision of a certificate of incorporation,
agreement (including but not limited to any indemnification insurance contract),
vote of stockholders or disinterested directors or otherwise.

            Section 3. Fiscal Year. The fiscal year of the Corporation shall
begin October 1 and end September 30.

                                   ARTICLE IV

                                   AMENDMENTS

            Section 1. By-Law Amendments. The by-laws of the Corporation may be
made, altered or repealed by vote of the stockholders at the time entitled to
vote in the election of directors. The by-laws may also be made, altered or
repealed by the Board of Directors, but any by-laws adopted by the Board may be

      Manufacturers and Traders Trust Company
      One M&T Plaza
      Buffalo, New York 14203

            RE:   CVC Products, Inc.

      Gentlemen:

            We have acted as special counsel to CVC Products, Inc., a Delaware
      corporation ("Borrower"), in connection with certain credit facilities to
      be made by Manufacturers and Traders Trust Company ("Bank") to Borrower
      pursuant to a certain Loan Agreement of even date herewith ("Closing
      Date") between Bank and Borrower, dated as of March 31, 1998 (the "Loan
      Agreement"). Furthermore, we have acted as special counsel to CVC, Inc., a
      Delaware corporation ("Parent") and have advised it in connection with
      certain matters pertaining to the Loan Agreement. Unless otherwise noted,
      the agreements referred to in (i) through (ix) below were executed on the
      Closing Date, as of March 31, 1998. We are giving the opinions set forth
      below at the request of Borrower and Parent.

            In our capacity as special counsel to Borrower and Parent, we have
      reviewed the Loan Agreement and the following documents, as executed:

            (i)   $8,000,000 Term Note, dated as of March 31, 1998, executed by
                  Borrower in favor of Bank ("Term Note");

            (ii)  $10,000,000 Grid Note, dated as of March 31, 1998, executed by
                  Borrower in favor of Bank ("Grid Note");

            (iii) Trademark Collateral Security and Pledge Agreement executed by
                  Borrower, Parent and Bank dated as of March 31, 1998
                  ("Trademark Agreement");

            (iv)  Patent Collateral Assignment and Security Agreement executed
                  by Borrower, Parent and Bank dated as of March 31, 1998
                  ("Patent Agreement");

            (v)   Amended and Restated Continuing Guaranty, dated as of March
                  31, 1998, executed by Borrower in favor of Bank ("Borrower
                  Guaranty");

            (vi)    Amended and Restated General Security Agreement, dated
                    as of March 31, 1998, executed by Borrower in favor of
                    Bank ("Borrower GSA");

            (vii)   Amended and Restated Continuing Guaranty, dated as of
                    March 31, 1998, executed by Parent in favor of Bank
                    ("Parent Guaranty");

            (viii)  Amended and Restated General Security Agreement, dated
                    as of March 31, 1998, executed by Parent in favor of
                    Bank ("Parent GSA"); and

            (ix)    Landlord/Mortgagee Waiver, dated as of March 31, 1998,
                    executed by Parent in favor of Bank ("Landlord Waiver").

            The Term Note, Grid Note, Borrower Guaranty and Borrower GSA are
      hereinafter collectively referred to as the "Borrower Loan Documents." The
      Parent Guaranty, Parent GSA and Landlord Waiver are hereinafter
      collectively referred to as the "Guarantor Loan Documents." The Borrower
      Loan Documents, the Guarantor Loan Documents, the Trademark Agreement and
      the Patent Agreement are referred to collectively as the "Loan Documents."

            We have also examined the Certificate of Incorporation and By-Laws
      of Borrower and Parent and copies, certified or otherwise identified to
      our satisfaction, of such other documents, records and certificates of
      public officials and of the Borrower and Parent, made such inquiries of
      officers of Borrower and Parent and considered such questions of law as we
      deemed necessary for the purpose of rendering the opinions set forth
      herein.

            As to questions of fact material to the opinions set forth herein,
      we have, when relevant facts were not independently established, made
      inquiries as to such questions of fact of officers of Borrower and Parent
      and relied upon certificates of, and information received from, officers
      of Borrower and Parent, in each case, copies of which are annexed hereto
      as exhibits. As to any opinions expressed herein "to our knowledge," such
      knowledge is a based solely upon certificates of, and information received
      from, officers of Borrower and Parent and any actual knowledge we may have
      from any other source. We have not independently investigated or verified
      the facts represented in such certificates or information and do not opine
      as to the accuracy of any such facts.

            In rendering the opinions set forth below, we have assumed that:

            A. Authority of Bank. Bank has all requisite power and authority to
      (i) consummate the transactions described in the Loan Documents, (ii)
      execute and deliver the Loan Documents to which it is a party and (iii)
      perform its obligations thereunder.

            B. Execution by Bank. Bank has duly and validly authorized, executed
      and delivered the Loan Documents to which it is a party.

            C. Modifications. There are no oral or written modifications of or
      amendments to the Loan Documents.

            D. Authenticity of Documents. All documents submitted to us as
      originals are authentic and complete; all documents submitted to us as
      certified, photostatic or conformed copies conform to the original
      documents; all signatures on all documents are genuine; and all public
      records reviewed are accurate and complete.

            E. Ownership of Collateral. Borrower is in possession of, and owns
      or has all applicable rights to use, the collateral described in the
      Trademark Agreement and Patent Agreement. Borrower and Parent are the
      owners of the collateral described in the Borrower GSA and Parent GSA,
      respectively.

            F. Recording of Trademark Agreement and Patent Agreement. The
      Trademark Agreement and Patent Agreement will be duly recorded in the
      appropriate recording offices.

            12. To our knowledge, there is no action, suit or proceeding
      pending, or overtly threatened by written communication, against Borrower
      or expressly affecting its assets wherein an unfavorable decision, ruling
      or finding, in any case or in the aggregate, would materially adversely
      affect the Borrower's financial condition or any of its assets, or the
      validity or enforceability of any of the Borrower Loan Documents, the
      Trademark Agreement or the Patent Agreement.

            13. To our knowledge, there is no action, suit or proceeding
      pending, or overtly threatened by written communication, against Parent or
      expressly effecting its assets wherein an unfavorable decision, ruling or
      finding, in any case or in the aggregate, would materially adversely
      affect Parent's financial condition or any of its assets, or the validity
      or enforceability of any of the Guarantor Loan Documents, the Trademark
      Agreement or the Patent Agreement.

            The opinions expressed above are subject to the following
      qualifications:

                  (a) the enforceability of the Loan Documents may be limited by
            the time of recording of the Patent Agreement and the Trademark
            Agreement, and by applicable bankruptcy, reorganization, insolvency,
            moratorium, fraudulent conveyance, and other similar laws now or
            hereafter in effect relating to or affecting creditor's rights
            generally;

                  (b) the enforcement of rights and remedies under the Loan
            Documents may be limited by (i) general principles of equity,
            regardless of whether such enforcement is considered in a proceeding
            in equity or at law, or (ii) the policies underlying applicable law;

                  (c) we express no opinion as to the enforceability of the
            self-help, non-judicial remedies provided to Bank in the Loan
            Documents (including, inter alia, remedies purportedly based upon
            the appointment of Bank as attorney-in-fact of Borrower);

                  (d) certain provisions in the Loan Documents may be rendered
            unenforceable or limited by applicable laws and judicial decisions;
            but such laws and judicial decisions do not render the Loan
            Documents legally inadequate remedies for the realization of the
            principal benefits and security intended to be provided thereby;

                  (e) enforceability of the Loan Documents may be limited by any
            unconscionable or inequitable conduct on Bank's part, defenses
            arising from Bank's failure to act in accordance with the terms and
            conditions of the Loan Documents and defenses arising as a result of
            Bank's failure to act in good faith and in a commercially reasonable
            manner;

                  (f) we express no opinion as to the validity or enforceability
            of any waiver of service of judicial process, or any provisions of
            any of the Loan Documents which might be construed as a waiver of
            counterclaims or defenses;

                  (g) we express no opinion as to (i) compliance with or the
            effect of any applicable health, safety, zoning, land use,
            environmental, tax, anti-trust or securities law, rule, regulation
            or ordinance; (ii) the existence or state of title of any real or
            personal property which may be the subject of any of the Loan
            Documents; (iii) the priority of any liens or security interest
            created or purported to be created by any of the Loan Documents;
            (iv) the perfection of any security interest in the Collateral; or
            (v) the Bank's right to collect any payment due to the extent that
            such payment constitutes a penalty, forfeiture or late payment
            charge;

                  (h) we express no opinion as to the enforceability of the
            provisions of the Grid Note and Loan Agreement requiring payment on
            demand;

                  (i) we express no opinion as to the enforceability of Section
            6.2 of the Trademark Agreement or Section 5.2 of the Patent
            Agreement;

                  (j) we express no opinion as to the enforceability of the
            provisions of Section 8 of the Trademark Agreement with respect to
            the sale of any Trademark apart from its Associated Goodwill and the
            business symbolized by such Trademark; and

                  (k) we express no opinion as to the enforceability of the
            Trademark Agreement to the extent that it purports to independently
            assign the Pledged Trademarks as opposed to being an assignment in
            furtherance of a security interest granted in the Pledged
            Trademarks.

            This opinion is specifically limited to the present General
      Corporation Law of the State of Delaware and the present internal laws of
      the State of New York and federal law of the United States, and no opinion
      is expressed as to the effect that the law of any other jurisdiction might
      have upon the subject matter of the opinions expressed herein under the
      conflicts of law principles or otherwise.

            This opinion is being rendered solely for the benefit of Bank in
      connection with the transactions contemplated by the Loan Documents. No
      other person may rely on this opinion for any purpose without the express
      written consent of the undersigned. This opinion is limited to the matters
      set forth herein, no opinion may be inferred or implied beyond the matters
      expressly stated herein, and this opinion must be read in conjunction with
      the assumptions, limitations, exceptions and qualifications set forth in
      this letter.

            This opinion is rendered as of the date hereof, and no opinion is
      expressed as to matters referred to herein on any subsequent date.


                                     Very truly yours,

      I, Emilio O. DiCataldo, as a Senior Vice President and Chief Financial
Officer of CVC Products, Inc., a Delaware corporation ("Borrower"), do hereby
certify to Nixon, Hargrave, Devans & Doyle LLP ("NHD&D"), in connection with
their opinion of counsel (the "Opinion"), dated April 14, 1998, addressed to
Manufacturers and Traders Trust Company ("M&T"), as follows:

      1. All capitalized terms used herein and not otherwise defined shall have
the meanings ascribed thereto in the Opinion.

      2. Except as may be set forth in the Officer's Certificate delivered to
M&T dated April 2, 1998, there have been no amendments to the Articles of
Incorporation or By Laws of Borrower.

      3. To the best of my knowledge, Borrower has the requisite corporate power
and authority to conduct its business as it is presently conducted.

      4. To the best of my knowledge, Borrower's execution and delivery of the
Borrower Loan Documents, the Trademark Agreement and the Patent Agreement and
Borrower's performance of its obligations under the Borrower Loan Documents, the

any of the provisions of, or constitute a default under, any agreement or
instrument to which Borrower is a party or by which any of Borrower's assets is
bound, (b) violate any existing judgment, order, writ, injunction or decree
expressly applicable to Borrower, (c) violate any existing law, rule, regulation
or ordinance applicable to Borrower or (d) result in the creation or imposition

party to, nor are Borrower's assets bound by, any agreements or instruments with

on Borrower's ability to incur additional indebtedness.

      5. To the best of my knowledge, there is no action, suit or proceeding
pending, or overtly threatened by written communication, against Borrower or
expressly affecting its assets wherein an unfavorable decision, ruling or
finding, in any case or in the aggregate, would materially adversely affect the
validity or enforceability of any of the Borrower Loan Documents the Trademark
Agreement or the Patent Agreement..

      6. Borrower has consented to the issuance of the Opinion by NHD&D to M&T.

                             APPLICATION OF PROCEEDS

      On April 14, 1998 ("Closing Date"), CVC PRODUCTS, INC. ("Borrower"),
executed and delivered to MANUFACTURERS AND TRADERS TRUST COMPANY ("Bank"), an
$8,000,000.00 Term Note ("Term Note"). The proceeds of the Term Note shall be
applied to partially refinance, to the extent of $8,000,000.00, the unpaid
principal balance due Bank under a $10,000,000.00 Grid Note dated January 30,
1998 ("1/30/98 Note"). Borrower acknowledges to Bank that on the Closing Date,
the 1/30/98 Note had an unpaid principal balance of $9,850,000.00.

      On the Closing Date, Borrower also executed a Loan Agreement ("Loan
Agreement") which provides for, among other things, a $10,000,000.00 line of
credit ("Line"). Loans under the Line are evidenced by Borrower's $10,000,000.00
Grid Note executed by Borrower on the Closing Date ("Grid Note"). On the Closing
Date, Borrower requests a $4,988,042.50 advance under the Line, the proceeds of
which will be distributed by Bank as follows:

      a.    $1,850,000.00 to partially refinance the unpaid principal balance
            due Bank under the 1/30/98 Note on the Closing Date.

      b.    $3,075,000.00 to refinance in full the unpaid principal balance due
            Bank under Borrower's $4,750,000.00 Grid Note dated April 9, 1998
            ("4/9/98 Note").

      c.    $13,042.50 to pay Woods, Oviatt, Gilman, Sturman & Clarke, LLP
            ("Woods, Oviatt") for Bank's attorneys' fees ($8,500.00) and
            estimated disbursements ($4,542.50). Borrower will pay to Woods,
            Oviatt the balance due for any disbursements when billed.

      d.    $50,000.00 to be retained by Bank in payment of the Up-Front Fee
            provided for in the Agreement.

      Borrower agrees that Bank may without further notice to Borrower, debit
any account of Borrower maintained at Bank for all accrued interest due Bank on
the 1/30/98 Note, and the 4/9/98 Note through the Closing Date (or the following
business day if the proceeds of the Term Note and advance under the Line are not
advanced by Bank until that date).
<PAGE>

      The above application of proceeds is acceptable to Borrower.

      Borrower acknowledges that although Term Note and Grid Note are dated as
of March 31, 1998, no proceeds of either note were advanced until the Closing
Date.

                          AMENDMENT TO LOAN AGREEMENT

      This AMENDMENT TO LOAN AGREEMENT ("Amendment"), dated as of September 22,
1999, between MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking
corporation, with a principal office located at One M&T Plaza, Buffalo, New York
14240 (the "Bank") and CVC PRODUCTS, INC., a Delaware corporation, with a

time the "Loan Agreement"); and

      WHEREAS, pursuant to the Loan Agreement, the Bank agreed to provide the
Borrower with an $8,000,000 term loan (the "Term Loan"), a $10,000,000

      3. Section b. in Insert 1 of the Rider to Loan Agreement, dated March 31,
1998, (as amended, restated or replaced from time to time the "Rider") between
Bank and Borrower is hereby deleted in full and replaced with the following:

            b. $15,000,000.00 Line of Credit.

                  (i) Subject to the terms and conditions of this Agreement,
Bank shall establish on September 22, 1999 (the "Amended Effective Date") for
the benefit of Borrower a discretionary line of credit ("Line of Credit") in the
maximum principal amount equal to the lesser of Fifteen Million Dollars
($15,000,000.00) or the then existing Borrowing Base (the "Maximum Credit").
Borrowing Base is defined below. Loans under the Line of Credit are
discretionary with Bank and conditioned upon prior approval by Bank.

                  (ii) The fact that a particular loan request pursuant to the
Line of Credit is disapproved by Bank shall have no effect on the Line of
Credit, nor on Borrower's rights to make future requests for loans under the
Line of Credit, nor on Borrower's obligation to pay the 1999 Grid Note (defined
below) and any other indebtedness of Borrower to Bank in full. Provided that
Bank gives approval to the requested borrowing, Borrower may borrow, repay and
reborrow under the Line of Credit, so long as the unpaid principal balance of
the 1999 Grid Note does not exceed the Maximum Credit.

                  (iii) Requests for a loan under the Line of Credit may be oral
(in person or by telephone) or in writing from an authorized person named in the
1999 Grid Note ("Authorized Person"), shall be made at least two (2) business
days before any LIBOR Rate Loan, and shall specify a date on which funds are
requested to be made available, which date shall be a business day in New York
State, the amount to be borrowed, the type of loan and, if a LIBOR Rate Loan,
the applicable Interest Period. No more than eight (8) LIBOR Rate Loans may be
outstanding at one time. Borrower will be bound by such instructions. Borrower
hereby indemnifies and holds Bank harmless from any liability (including Bank's
reasonable attorneys' fees) which may arise as a result of Bank's reliance on
telephone requests for borrowing and/or prepayment instructions from any person
identifying himself as an Authorized Person. Each Prime Loan shall be in the
minimum principal amount of $100,000.00 or a $10,000 integral multiple thereof,
and each LIBOR Rate Loan shall be in the minimum principal amount of $500,000.00
or a $100,000 integral multiple thereof, except for a borrowing in a lesser
amount equal to the unused portion of the Maximum Credit, which must be a Prime
Loan.

                  (iv) Each loan made by the Bank to Borrower under the Line of
Credit ("Approved Loan") shall be processed by debiting the Line of Credit and
crediting Borrower's checking account with Bank for the amount of the Approved
Loan or by forwarding or applying the Approved Loan proceeds as otherwise agreed
by Bank and Borrower. The Approved Loan shall be deemed made immediately upon
the crediting of the Approved Loan proceeds to Borrower's checking account with
Bank or forwarding or applying the Approved Loan proceeds as otherwise agreed by
Bank and Borrower.


                                      -3-
<PAGE>

                  (v) Each Approved Loan is payable on demand and shall be
evidenced by an Amended and Restated Standard LIBOR Grid Note (with blanks
appropriately completed) (the "1999 Grid Note"), which Borrower shall execute
and deliver to Bank on the Amended Effective Date. The 1999 Grid Note shall be
in the form of Exhibit A attached to the Amendment, with blanks appropriately
completed.

                  (vi) Conversions and Contributions -- The Borrower shall have
the right to convert Approved Loans of one type (i.e., Prime Loans or LIBOR Rate
Loans) into Approved Loans of another type, or continue Approved Loans of the
same type, pursuant to the terms of the 1999 Grid Note.

                  (vii) All outstanding amounts under the Line of Credit,
(except as specifically provided in the 1999 Grid Note), shall bear interest
until paid in full (A) for Prime Loans, at the Prime Rate and (B) for LIBOR Rate
Loans, at the LIBOR Rate. Interest shall be calculated based on actual days
elapsed divided by a year of three hundred sixty (360) days. Changes in the rate
of interest applicable to the 1999 Grid Note shall become effective
automatically and without notice at the time of changes in the Prime Rate.

                  (viii) Payments of all accrued interest under the 1999 Grid
Note shall be made, in the case of Prime Loans, on the first day of each month
commencing the first month after the Prime Loan is made and, in the case of
LIBOR Rate Loans, on the last day of the applicable Interest Period, except if a
LIBOR Rate Loan has a six (6) month Interest Period, interest shall be paid on
the three (3) month anniversary of such LIBOR Rate Loan and on the last day of
the Interest Period, unless payment of the 1999 Grid Note is sooner demanded by
Bank, in which case all accrued interest shall be immediately due and payable in
full. Principal outstanding pursuant to the 1999 Grid Note shall be due and
payable in full at any time upon demand by Bank. In the event Borrower becomes
aware, or receives notice (oral or written) from Bank, that principal amounts
outstanding under the Line of Credit exceed the Maximum Credit at any time,
Borrower promptly shall make a principal payment to Bank sufficient to reduce
outstanding principal amounts to the Maximum Credit without the necessity of a
demand by Bank.

                  (ix) LIBOR Rate Loans -- Additional provisions regarding LIBOR
Rate Loans are contained in the 1999 Grid Note.

                  (x) As used in this Agreement, the following definitions shall
apply:

                        "Accounts" means all accounts, contract rights, chattel

                              (h)   Each representation and warranty with
                                    respect to the Account made by Borrower or
                                    any Guarantor to the Bank in any security
                                    agreement executed by Borrower or any
                                    Guarantor is true and complete;

                              (i)   The Account is subject to the perfected
                                    first priority security interest of the Bank
                                    and to no other security interest, lien,
                                    assignment or encumbrance of any kind; and

                              (j)   The Bank has not notified Borrower that the
                                    Account or the account debtor, in the Bank's
                                    reasonable judgment, is unsatisfactory.

                        "Eligible Inventory" means all first quality inventories
of finished products, work-in-process inventory and raw materials owned by the
Borrower or Commonwealth, valued at the lower of cost (on a FIFO basis) or
market, minus all perishable or non-saleable inventories and such reserves as
Borrower or Commonwealth has historically established, including, but not
limited to, (a) shrinkage reserves, (b) markdown reserves, and (c) reserves
which restore standard costs to actual costs. Neither so-called mold inventories
or inventories on consignment, (except that with respect to consignments,
Eligible Inventory shall include inventory shipped to customers at sites located
in the United States for evaluation by the customer, provided that no more than
75 days elapse from the date of shipment and further provided that the aggregate
value of such Eligible Inventory on consignment does not exceed $2,500,000.00),
are Eligible Inventories and all such inventories shall be excluded from the
calculation thereof. Eligible Inventories must arise from the Borrower's or
Commonwealth's ordinary course of business as it exists on the date of this
Amendment, must at all times be subject to the perfected, first priority
security interest of Bank and no other lien, must be located on Borrower's or
Commonwealth's premises within the United States (which are covered by a
landlord/mortgagee waiver acceptable to the Bank), must conform in all respects
to warranties contained in this Amendment and all security or other related
agreements and documents, and must not be subject to a licensing agreement with
third parties unless Bank shall have received consents or acknowledgements or
other assurances satisfactory to the Bank from such third parties as may be
deemed necessary or desirable to facilitate Bank's realization


                                      -7-

upon such inventory. Any inventory subject to an Eligible Account shall also not
constitute Eligible Inventory. The calculation of Eligible Inventory must be
satisfactory to the Bank in its reasonable discretion.

                        "Eurocurrency Reserve Rate" means, for any LIBOR Rate
Loan for any Interest Period therefor, the daily average of the stated maximum
rate (expressed as a decimal) at which reserves (including any marginal,
supplemental or emergency reserves) are required to be maintained during such
Interest Period (or any part thereof) under Regulation D by the Bank against
"Eurocurrency Liabilities" (as such term is used in Regulation D), but without
the benefit or credit of proration, exemptions or offsets that might otherwise
be available to the Bank from time to time under Regulation D. Without limiting
the effect of the foregoing, the Eurocurrency Reserve Rate shall reflect any
other reserves required to be maintained by the Bank against any category of
liabilities that includes deposits by reference to which the LIBOR Rate for
LIBOR Rate Loans is determined, or any category of extension or credit or other
assets that include LIBOR Rate Loans.

                        "Fixed Rate" shall mean 1.85% above the Cost of Funds.

                        "Fixed Rate Loan" means a loan bearing interest at the
Fixed Rate.

                        "Interest Period" means, with respect to any LIBOR Rate
Loan, each period commencing on the date such LIBOR Rate Loan is made or
converted from a Prime Loan and ending on the numerically corresponding day in
the first, second, third or sixth calendar month thereafter, as the Borrower
may select, except that each Interest Period which commences on the last
business day of a calendar month (or on any day for which there is no
numerically corresponding day in the appropriate subsequent calendar month)
shall end on the last business day of the appropriate subsequent calendar month.

                        Notwithstanding the foregoing, (i) each Interest Period
that would otherwise end on a day which is not a business day, shall end on the
next succeeding business day (or, if such next succeeding business day falls in
the next succeeding calendar month, on the next preceding business day); and
(ii) notwithstanding clause (i) above, no Interest Period shall have a duration
of less than one month without Bank's consent and, if the Interest Period for
any LIBOR Rate Loan would otherwise be a shorter period, such LIBOR Rate Loan
shall not be available hereunder for such period.

                        "Letters of Credit" shall mean the Letters of Credit
described in Section b.(xiv) of Insert 1 of this Rider.

                        "Letters of Credit Obligations" means all obligations of
the Borrower to reimburse the Bank for all amounts drawn under the Letters of
Credit pursuant to the Reimbursement Agreement (as defined below).

<PAGE>

                        "LIBOR Base Rate" means, with respect to any Interest
Period for a LIBOR Rate Loan, the rate per annum equal to the quotient obtained
by dividing (and rounded upward to the nearest 1/100 of 1%) (i) LIBOR (as
determined below) on a date two Business Days prior to the beginning of an
Interest Period ("Interest Setting Date"), at which deposits in United States
Dollars for a period and in an amount, comparable to the Interest Period and the
principal amount of the LIBOR Rate Loan are offered to prime banks in the London
Interbank market at 11:00 a.m. (London time) on that day ("Reference Bank") by
(ii) a percentage equal to 100% minus the Eurocurrency Reserve Rate. LIBOR shall
be determined by the Bank on the Interest Setting Date from Telerate Page 3750
as of 11:00 a.m. (London time) on such date, or if such page or such service
ceases to display such information, from such other service or method as Bank
may select.

                        "LIBOR Rate" means for a loan under the Line of Credit,
the LIBOR Base Rate plus two and one quarter percent (2.25%), and for a loan
under the Loan Limit, the LIBOR Base Rate plus two and one-half percent (2.5%).

                        "LIBOR Rate Loan" means a loan bearing interest at the
LIBOR Rate.

                        "Prime Loan" means any loan under this Agreement bearing
interest at the Prime Rate.

                        "Prime Rate" shall mean the rate of interest designated
by the Bank as its prime rate from time to time as a guide for establishing
lending rates to customers, irrespective of the actual rate charged to any
specific customer with respect to any specific transaction.

                  (xi) Borrower also will submit to Bank within thirty (30) days
after the end of each calendar month a Borrowing Base Certificate reporting on
the Borrowing Base as of the end of the previous month together with all
supporting documentation requested by Bank and a monthly backlog report. Each
Borrowing Base Certificate shall be in form satisfactory to the Bank and
certified to Bank by Borrower's Chief Financial Officer. Borrower will also,
within forty-five (45) days of the end of each of its first three fiscal
quarters, provide Bank with a certificate executed by its Chief Financial
Officer, stating that he has read this Amendment, knows its contents and that to
his knowledge, Borrower is in compliance with all financial covenants contained
in this Amendment, and no Event of Default has occurred under this Amendment,
and no conditions exists, which, with notice, lapse of time or both, would
constitute an Event of Default under this Amendment. The certificate shall also
show the computations required to establish Borrower's compliance with each
financial covenant during the period covered by the certificate. Borrower shall
also provide Bank with such additional financial and other information as Bank
shall reasonably, from time to time, request.

                  (xii) Bank may perform full field audits of Borrower's
accounts receivable and inventories during normal business hours at Borrower's
expense once a


                                      -9-
<PAGE>

year. Bank reserves the right, in its sole discretion and at its own expense, to
perform field audits of Borrower's accounts receivable and inventories more than
once per year. Notwithstanding the foregoing, during the continuance of an Event
of Default, the Bank may perform an unlimited amount of full field audits at
Borrower's expense.

                  (xiii) The Line of Credit will terminate on the demand by Bank
of amounts outstanding under the 1999 Grid Note. Bank may also terminate
Borrower's right to make requests for loans under the Line of Credit at any time
by giving Borrower written notice of termination without making a demand for
payment of the 1999 Grid Note. The giving of such notice by Bank shall not
effect Bank's rights under this Amendment or under the 1999 Grid Note or under
any other agreement, instrument or document made by Borrower with or in favor of
Bank, nor on Borrower's obligation to pay the 1999 Grid Note in full according
to its terms.

                  (xiv) Subject to the terms and conditions of this Agreement
and provided the Borrower complies with all application requirements of the Bank
for issuing letters of credit, the Borrower may request that the Bank make
standby letters of credit available for the account of the Borrower; provided
that (a) the Borrower shall not request that the Bank issue any Letter of
Credit, if, after giving effect to such issuance, the sum of the aggregate
Letter of Credit Obligations plus the aggregate outstanding principal amount of
the 1999 Grid Note would exceed the Maximum Credit; and (b) the Borrower shall
not request that the Bank issue any Letter of Credit, and the Bank will not
issue any letter of credit if after giving effect to such issuance, the
aggregate Letter of Credit Obligations would exceed $1,000,000.

                        The Borrower will pay to the Bank letter of credit fees
on the date of issuance of the Letters of Credit and on each anniversary date
thereafter if the Letters of Credit are renewed, equal to one and one-quarter
percent (1 1/4%) of the aggregate face amount of all outstanding Letter of
Credit, or such other amount as may be customarily charged by the Bank. In
addition, Borrower shall pay to the Bank all other fees customarily charged by
the Bank in connection with the issuance of the Letters of Credit.

                        Prior to issuance of any Letters of Credit hereunder,
the Borrower will execute a Letter of Credit Reimbursement Agreement (the
"Reimbursement Agreement") substantially in the form of Exhibit B attached to
the Amendment that is satisfactory to the Bank, documenting its Obligations with
respect to the Letters of Credit. To the extent of any conflict between the
terms of this Amendment and the Reimbursement Agreement or any letter of credit
application, the terms of this Amendment shall control.

      4. Paragraph c. in Insert 1 of the Rider is hereby deleted in full and
replaced with the following:

            c. $3,000,000.00 Loan Limit.

                  (i) Subject to the terms and conditions of this Agreement, the
Bank hereby establishes for the benefit of the Borrower a discretionary offering
basis loan limit ("Loan Limit") in the maximum principal amount outstanding at
any one time of Three Million Dollars ($3,000,000.00). Loans under the Loan
Limit shall be either Prime Loans, LIBOR Rate Loans or Fixed Rate Loans. Prime
Loans shall be in the minimum principal amount of $100,000, or a $10,000
integral multiple thereof, and LIBOR Rate Loans and Fixed Rate Loans shall be in
the minimum principal amount of $500,000, or a $100,000 integral multiple
thereof. Under the Loan Limit, an authorized officer of the Bank, in his sole
discretion, may make advances to Borrower under the Loan Limit on the terms
specified below. Borrower acknowledges that such officer may refuse to make any
advances under the Loan Limit to Borrower for any reason, or for no reason
whatsoever.

                  (ii) Provided that all of the conditions for advances
contained herein are satisfied, including approval of a requested advance,
advances under the Loan Limit will be made from time to time at the request of
the Borrower by credits to the Borrower's accounts at the Bank.

                  (iii) Unless extended by the Bank in writing in its sole
discretion, the Loan Limit will be available until terminated by Bank upon
written notice to the Borrower. Borrower acknowledges that Bank may terminate
the Loan Limit at any time in its sole discretion.

                  (iv) With each advance under the Loan Limit, the Borrower
shall execute a term note evidencing such indebtedness to the Bank (each such
note, a "Loan Limit Note"). Each Loan Limit Note shall be in substantially the
form of Exhibit C-1 attached to the Amendment if a Fixed Rate Loan and Exhibit
C-2 attached to the Amendment if a Prime Loan or LIBOR Rate Loan. Each such note
shall be dated the date the Borrower executes the note, be payable to the order
of Bank, be in the principal amount of the advance and provide for interest
accruing, prior to an Event of Default, at a rate equal to (1) the Prime Rate,
(2) the Fixed Rate or (3) the LIBOR Rate. Each Loan Limit Note shall further
provide that, unless sooner accelerated, the original principal amount evidenced
thereby shall be repayable in such number of months as may be selected by Bank
which shall not be less than thirty-six (36) months nor more than sixty (60)
months. Accrued interest under each Loan Limit Note shall be due on the first
day of each calendar month for a Prime Loan or Fixed Rate Loan, and on the last
day of the Applicable Interest Period for a LIBOR Rate Loan, except if a LIBOR
Rate Loan has a six (6) month Interest Period, interest shall be paid on the
three (3) month anniversary of such LIBOR Rate Loan and on the last day of the
Interest Period, with the first interest payment due on the first day of the
first month following the date on which the note is executed and continuing

consolidated statements of operations, shareholders' equity and cash flows for
the nine (9) and twelve (12) months then ended, respectively, are complete and
correct, have been prepared in accordance with Generally Accepted Accounting
Principles consistently applied throughout the periods indicated and fairly
present the financial condition of the Borrower, as of the respective dates
thereof and the results of Borrower's operations and cash flow for the
respective periods covered thereby. Since June 30, 1999, there has been no
material adverse change in the condition, financial or otherwise, of the

            b. Registration Statement. Borrower has provided Bank with a true
and complete copy of the Amendment No. 3 to Registration Statement (File No.
356-33821) filed by Parent with the Securities and Exchange Commission on

contained therein) does not, and in the future neither the Registration
Statement nor any supplement nor amendment thereto, will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated or incorporated by reference therein or necessary to make the statement
therein not misleading (and in the case of the prospectus, not misleading in
light of the circumstances under which they were made).

            c. Subsidiaries and Affiliates. The Borrower is a wholly-owned
subsidiary of the Parent and neither Borrower nor Parent has any subsidiaries or
affiliates, except those listed in the attached "Schedule of Permitted
Subsidiaries and Affiliates".

Parent's sole assets are the capital stock of Borrower, Commonwealth and CVC
Process Solutions, Inc. Borrower is not a party to any material transaction with
any affiliate except for transactions which are in the ordinary course of
business and upon fair and reasonable terms not materially less favorable than
Borrower could obtain or become entitled to in an arm's length transaction with
an entity that is not an affiliate.

            As used herein, the following definitions apply:

                  "affiliates" means any entity which directly or indirectly, or
through one or more intermediaries, controls or is controlled by or is under
common control with Parent, Borrower or any subsidiary of Parent or Borrower.

                  "control", "controlled by" or "under common control" means,
but is not limited to, the beneficial ownership (as defined in Rule 13(d)
promulgated by the Securities Exchange Commission pursuant to Section 13(d) of
the Securities Exchange Act of 1934, as amended) of ten percent (10%) or more of
the outstanding shares of capital stock of any corporation having voting power
for the election of directors (whether or not at the same time stock of any
other class or classes has or might have voting power by reason of the happening
of any contingency) or ten percent (10%) or more of any equity interest in any
non-corporate entity, or any other interest through which the power to direct
the management or policies of a person may be exercised.

            f. Existing Indebtedness. Except as disclosed in the attached
"Schedule of Permitted Indebtedness," neither Parent nor Borrower has any
outstanding indebtedness or contingent liabilities (including, without
limitation, "off-balance sheet" liabilities) other than those liabilities
disclosed in the Borrower's balance sheet, dated as of June 30, 1999, and wages,
salary, trade payables and operating leases incurred in the ordinary course of
business since such date. Without limiting the foregoing, neither Parent nor
Borrower is an account party with respect to any letters of credit other than
those issued by Bank. Borrower shall not, without Bank's prior written consent,
modify the terms of any of its existing long-term debt or make any principal
payments on any long-term debt (other than debt to Bank) at any time for any
reason (whether before or after maturity hereof).

            k. Except as specified in Recordation Form Cover Sheet on Form PTO
1595, provided to Bank by Borrower on or about September 22, 1999, Borrower has
no patents issued by the U.S. Patents and Trademark Office ("PTO"), nor has
Borrower filed any other applications for patents with the PTO.

      7. The definition of Existing Bank Documents in subparagraph (j) of Insert
5 of the Rider is hereby amended by adding to such definition the following:

            (xvi) Master Lease Agreement, dated April 7, 1998, executed by
Borrower in favor of M&T Financial Corporation and Schedules Nos. 1, 2 and 3
thereto.

dividends and amounts paid or accrued for the repurchase of stock by the
Borrower during the Measurement Period.

2000, Net Income shall not include the in-process research and development

      a. Promise to Pay. For value received, Borrower promises to pay to the
order of the Bank on demand, the Maximum Principal Amount or the Outstanding
Principal Amount, if less; plus interest as set forth below and all reasonable
fees and costs (including without limitation attorneys' fees and disbursements,
whether for internal or outside counsel) the Bank incurs in order to collect any
amount due under this Note, to negotiate or document a workout or restructuring,
or to preserve its rights or realize upon any guaranty or other security for the
payment of this Note ("Expenses").

      b. Interest. Each Loan shall earn interest on the Outstanding Principal
Amount thereof calculated on the basis of a 360-day year for the actual number
of days of each year (365 or 366) that on each day shall be:

            i. LIBOR Rate Loans. Interest shall accrue on a LIBOR Rate Loan from
            and including the first day of the Interest Period applicable
            thereto until, but not including, the last day of such Interest
            Period or the day the LIBOR Rate Loan is paid in full (if sooner) at
            a rate per annum equal to the LIBOR Rate in effect on the following
            dates (depending on the circumstance):

<PAGE>

            (i) for new LIBOR Rate Loans, the Business Day the Bank receives (or
            is deemed to receive) a Request for a LIBOR Rate Loan; (ii) for
            conversions and continuations of LIBOR Rate Loans pursuant to
            Section 4, the Business Day the Bank receives (or is deemed to
            receive) the Notice of Conversion or Notice of Continuation, as the
            case may be, in accordance with Section 4(b); for LIBOR Rate Loans
            where the Automatic Continuation Option is selected, the Automatic
            Adjustment Date for such LIBOR Rate Loan.

            ii. Base Rate Loans. Interest shall accrue on a Base Rate Loan from
            and including the first date the Base Rate Loan was made (i.e., the
            Draw Date or the Conversion Date, as the case may be) to, but not
            including, the day such Base Rate Loan is paid in full or converted,
            at the rate per annum equal to the Base Rate. Any change in the Base
            Rate resulting from a change in the Bank's prime rate shall be
            effective on the date of such change.

      c. Maximum Legal Rate. It is the intent of the Bank and of Borrower that
in no event shall interest be payable at a rate in excess of the maximum rate
permitted by applicable law (the "Maximum Legal Rate"). Solely to the extent
necessary to prevent interest under this Note from exceeding the Maximum Legal
Rate, any amount that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically canceled, and, if received by the Bank, shall be refunded to
Borrower.

      d. Payments; Late Charge; Default Rate. Payments shall be made in
immediately available United States funds at any banking office of the Bank.
Absent demand for payment in full, interest shall be due and payable as follows:
unless demanded sooner, (i) in respect to each Base Rate Loan, monthly when
invoiced and (ii) in respect to each LIBOR Rate Loan, on the last day of each
Interest Period applicable thereto except if a LIBOR Rate Loan has a six month
Interest Period, interest shall be paid on the three month anniversary of the
LIBOR Rate Loan and on the last day of the Interest Period. If payment is not
received within five days of its due date, Borrower shall pay a late charge
equal to the greatest of (a) 5% of the delinquent amount, (b) the Bank's then
current late charge as announced by the Bank from time to time, or (c) $50.00.
In addition, if the Bank has not actually received any payment under this Note
within thirty days after its due date, from and after such thirtieth day the
interest rate for all amounts outstanding under this Note shall automatically
increase to 5 percentage points above the higher of the Base Rate or the highest
LIBOR Rate, and any judgment entered hereon or otherwise in connection with any
suit to collect amounts due hereunder shall bear interest at such default rate.
Payments may be applied in any order in the sole discretion of the Bank but,
prior to demand, shall be applied first to past due interest, Expenses, late
charges, and principal payments, if any, which are past due, then to current
interest and Expenses and late charges, and last to remaining principal.

      e. Prepayment of LIBOR Rate Loans. If (i) Borrower pays, in whole or in
part, any LIBOR Rate Loan, before the expiration of its respective Interest Rate
Period, (ii) fails to draw down, in whole or in part, a LIBOR Rate Loan after
giving a Request therefor, (iii) otherwise tries to revoke any LIBOR Rate Loan,
in whole or in part, or (iv) there occurs a Bankruptcy Event or the applicable
rate is converted from the LIBOR Rate to the Base Rate pursuant to Section 4(d),
then Borrower shall be liable for and shall pay the Bank, on demand, the higher
of $250.00 or the actual amount of the liabilities, expenses, costs or funding
losses that are a direct or indirect result of such prepayment, failure to draw,
early termination of an Interest Period, revocation, bankruptcy or otherwise,
whether such liability, expense, cost or loss is by reason of (a) any reduction
in yield, by reason of the liquidation or reemployment of any deposit or other
funds acquired by the Bank, (b) the fixing of the interest rate payable on any
LIBOR Rate Loans or (c) otherwise. The determination by the Bank of the amount
of foregoing amount shall, in the absence of manifest error, be conclusive and
binding upon Borrower.

3. LOANS.

      a. General. Any Loan hereunder shall either be in the form of a Base Rate
Loan or a LIBOR Rate Loan. No Loan, or any portion thereof, shall be made to the
extent that the sum of the (i) principal amount of the requested Loan, or any
portion thereof and (ii) the Outstanding Principal Amount of all Loans under the
Note exceeds the Maximum Principal Amount under this Note. The Bank may make any
Loan in reliance upon any oral, telephonic, written, teletransmitted or other
request (the "Request(s)") that the Bank in good faith believes to be valid and
to have been made by Borrower or on behalf of Borrower by an Authorized Person.
The Bank may act on the Request of any Authorized Person until the Bank shall
have received from Borrower, and had a reasonable time to act on, written notice
revoking the authority of such Authorized Person. The Bank shall incur no
liability to Borrower or to any other person as a direct or indirect result of
making any Loan pursuant to this paragraph.

      b. Request for LIBOR Rate Loans. Borrower shall give the Bank its
irrevocable Request for a LIBOR Rate Loan specifying:

            i.    the Draw Date for the LIBOR Rate Loan, which shall be a two
                  (2) Business Days from the date the Request: provided, however
                  if a Request is received by the Bank after 2:00 p.m. (Eastern
                  Standard Time), the Request for the LIBOR Rate Loan shall be
                  deemed to have been received on the next Business Day;

            ii.   the aggregate amount of such LIBOR Rate Loan, which amount
                  shall not be less than the Minimum Borrowing Amount; and

            iii.  the applicable Interest Period (i.e., 1, 2, 3 or 6 month
                  Interest Period).

            iv.   whether Borrower is electing to have the Automatic
                  Continuation Option for such LIBOR Rate Loan.

      c. Requests for Base Rate Loans. Borrower may request any Base Rate Loan
not later than 2:00 p.m. (Eastern Standard Time) on any proposed Draw Date
specifying the aggregate amount of such Base Rate Loan.

      d. Delivery of Requests Delivery of a Notice or Request for a LIBOR Rate
Loan or a Base Rate Loan shall be made to the Bank at the following as follows,
or such other address designated by the Bank from time to time:

                        Manufacturers and Traders Trust Company

4. CONTINUATION and CONVERSION ELECTIONS.

      a.    Election. An Authorized Person of Borrower may, upon irrevocable
            Request to the Bank,

            i.    elect to convert on any Business Day any Base Rate Loan into a
                  LIBOR Rate Loan provided the amount converted is not less than
                  the Minimum Borrowing Amount; or

            ii.   elect to convert any or a part of LIBOR Rate Loan as of the
                  last day of the applicable Interest Period into a Base Rate
                  Loan provided no partial conversion of a LIBOR Rate Loan shall
                  reduce the outstanding principal amount of such LIBOR Rate
                  Loan to less than the Minimum Borrowing Amount; or

            iii.  elect to continue all or a part (subject to the Minimum
                  Borrowing Amount limitation) of any LIBOR Rate Loan as of the
                  last day of the Interest Period applicable to such LIBOR Rate
                  Loan with the same or different Interest Period provided no
                  partial continuation of a LIBOR Rate Loan with a different
                  Interest Period shall reduce the outstanding principal amount
                  of the LIBOR Rate Loan with the same Interest Period to less
                  than the Minimum Borrowing Amount.

      b.    Notice of Conversion/Continuation.

            i.    For an election under Section 4(a)(i) or 4(a)(iii), an
                  Authorized Person must deliver to the Bank by 2:00 p.m.
                  (Eastern Standard Time) on a Business Day a Notice of
                  Conversion ("Notice of Conversion") for an election under
                  Section 4(a)(i) or a Notice of Continuation ("Notice of
                  Continuation") for an election under Section 4(a)(iii)
                  specifying:

                  (a)   the aggregate amount of the Loans to be converted or
                        continued;

                  (b)   the duration of the requested Interest Period (i.e., 1,
                        2, 3 or 6 month Interest Period); and

                  (c)   whether the Automatic Continuation Option will be
                        activated for such LIBOR Rate Loan.

            ii.   The Continuation Date or Conversion Date (as the case may be)
                  shall be the later of (A) two (2) Business Days from the
                  Business Day the Bank receives the Notice of Conversion or
                  Notice of Continuation (either, a "Notice") in accordance with
                  the foregoing Section or (B) the last day of the relevant
                  Interest Period if a Notice is received by the Bank more than
                  two (2) Business Days before the last day of an Interest
                  Period. If a Notice is received after 2:00 p.m. (Eastern
                  Standard Time), the Notice will be deemed to have been
                  received on the next Business Day. Notice of Continuation
                  received more than two (2) Business Days before the end of an
                  Interest Period shall be deemed to have been received two (2)
                  Business Days before the end of such Interest Period for
                  purposes of determining the LIBOR Rate for the next Interest
                  Period per Section 2(b)(i). Accordingly, if, for example,
                  Borrower has a LIBOR Rate Loan with a one month Interest
                  Period ending on June 15 and wants to continue the LIBOR Rate
                  Loan with a two month Interest Period, Borrower must deliver
                  its Notice of Continuation identifying the new two month
                  Interest Period to the Bank by 2:00 p.m. (Eastern Standard
                  Time) on June 13 (provided that June 13 and June 14 are
                  Business Days).

            iii.  For LIBOR Rate Loans where Borrower has elected to activate
                  the Automatic Continuation Option, the Bank shall
                  automatically continue such LIBOR Rate Loan with an same
                  Interest Period initially selected by the Borrower. Once the
                  Automatic Continuation Option has been activated for a LIBOR
                  Rate Loan, the submission of a Notice of Conversion or a
                  Notice of Continuation with a different Interest Period shall
                  result in the cancellation of the Automatic Continuation
                  Option for such LIBOR Rate Loan.

            iv.   For an election under Section 4(a)(ii), an Authorized Person
                  may deliver to the Bank a Notice of Conversion at any time
                  during an Interest Period up to the last day of such Interest
                  Period or may have the LIBOR Rate Loan automatically convert
                  to a Base Rate Loan pursuant to Section 4(c). Any such Notice
                  of Conversion delivered during an Interest Period shall be
                  effective on the last day of the Interest Period.

            v.    The Bank may take action on any Notice in reliance upon any
                  oral, telephonic, written or teletransmitted Notice that the
                  Bank in good faith believes to be valid and to have been made
                  by Borrower or on behalf of Borrower by an Authorized Person.
                  No Notice may be delivered by e-mail. The Bank may act on the
                  Notice from any Authorized Person until the Bank shall have
                  received from Borrower, and had a reasonable time to act on,
                  written notice revoking the authority of such Authorized
                  Person, The Bank shall incur no liability Borrower or to any
                  other person as a direct or indirect result of acting on any
                  Notice under this Note. The Bank, in its reasonable
                  discretion, may reject any Notice that is incomplete.

      c. Expiration of Interest Period. If Borrower does not submit a Notice of
Continuation in accordance with Section 4(b)(i) and 4(b)(ii) so that the Bank
receives the Notice of Continuation at least two (2) Business Days before the
end of an Interest Period, the LIBOR Rate Loan shall automatically be converted
into a Base Rate Loan and such Loan shall accrue interest at the Base Rate until
two (2) Business Days after the Bank receives a Notice of Conversion pursuant to
Section 4(b)(i) and 4(b)(ii) electing to convert the Loan from a Base Rate Loan
to a LIBOR Rate Loan pursuant to Section 4(a)(i). A Notice of Continuation
received one (1) Business Day before the end of an Interest Period will not
effect a continuation of such Loan as a LIBOR Rate Loan. Rather, such LIBOR Rate
Loan shall automatically convert to a Base Rate Loan on the last day of the
Interest Period. The late Notice of Continuation, however, will be deemed to be
a Notice of Conversion that will be effective two (2) Business Days from the
date received by the Bank.

      d. Conversion upon Default Unless the Bank shall otherwise consent in
writing, if (i) Borrower has failed to pay when due, in whole or in part, the
indebtedness under the Note (whether by demand or otherwise), or (ii) there
exists a condition or event which with the passage of time, the giving of notice
or both shall constitute an event of default under any of Borrower's agreement
with the Bank, if any, Borrower may not elect to have a Loan converted or
continued as a LIBOR Rate Loan or have any Loan made as a LIBOR Rate Loan.
Further, the Bank, in its sole discretion, may (i) permit any outstanding LIBOR
Rate Loans to continue until the last day of the applicable Interest Period at
which time such Loan shall automatically be converted into a Base Rate Loan or
(ii) convert any outstanding LIBOR Rate Loans into a Base Rate Loan before the
end of the applicable Interest Period applicable to such LIBOR Rate Loan.
Notwithstanding the foregoing, if Borrower commences, or has commenced against
it, any proceeding or request for relief under any bankruptcy, insolvency or
similar laws now or hereafter in effect in the United States of America or any
state or territory thereof or any foreign jurisdiction or any formal or informal
proceeding for the dissolution or liquidation of, settlement of claims against
or winding up of affairs of Borrower (a "Bankruptcy Event"), any outstanding
LIBOR Rate Loans shall be automatically converted to Base Rate Loans without
further action by the Bank and Borrower's rights to have Base Rate Loans
converted under Section 4 shall be automatically terminated. Nothing herein
shall be construed to be a waiver by the Bank to have any Loan accrue interest
at the Default Rate of interest (which shall be calculated from the higher of
the LIBOR Rate or the Base Rate) or the right of the Bank to the amounts set
forth in Section 2(e) of this Note.


                                      -3-

5 SETOFF. The Bank shall have the right to set off against the amounts owing
under this Note any property held in a deposit or other account with the Bank or
any of its affiliates or otherwise owing by the Bank or any of its affiliates in
any capacity to Borrower or any guarantor or endorser of this Note. Such set-off
shall be deemed to have been exercised immediately at the time the Bank or such
affiliate elect to do so.

6 DEMAND FACILITY. The Bank may modify, restrict, suspend or terminate the
credit under this Note at any time for any reason and without affecting
Borrower's then existing obligation under this Note. The Bank shall have the
sole and absolute discretion whether to make any Loan or any potion of any Loan
requested by Borrower, and the Bank may refuse to make any requested Loan even
though the sum of the requested Loan and the Outstanding Principal Amount would
not exceed the Maximum Principal Amount. This is a demand Note and all amounts
hereunder shall become immediately due and payable upon demand by the Bank;
provided, however, that the Outstanding Principal Amount of this Note and all
accrued and unpaid interest shall automatically become immediately due and
payable upon the occurrence of a Bankruptcy Event with regard to Borrower or any
guarantor or endorser of this Note. Borrower hereby waives protest, presentment
and notice of any kind in connection with this Note.

7 BANK RECORDS CONCLUSIVE. The Bank shall set forth on a schedule attached to
this Note or maintained on computer, the date and original principal amount of
each Loan and the date and amount of each payment to be applied to the
Outstanding Principal Amount of this Note. The Outstanding Principal Amount set
forth on any such schedule shall be presumptive evidence of the Outstanding
Principal Amount of this Note and of all Loans. No failure by the Bank to make,
and no error by the Bank in making, any annotation on any such schedule shall
affect the Borrower's obligation to pay the principal and interest of each Loan
or any other obligation of Borrower to the Bank pursuant to this Note.

8 PURPOSE. Borrower certifies (a) that no Loan will be used to purchase margin
stock except with the Bank's express prior written consent for each such
purchase and (b) that all Loans shall be used for a business purpose, and not
for any personal, family or household purpose.

9 AUTHORIZATION. Borrower, if a corporation, partnership, limited liability
company, trust or other entity, represents that it is duly organized and in good
standing or duly constituted in the state of its organization and is duly
authorized to do business in all jurisdictions material to the conduct of its
business; that the execution, delivery and performance of this Note have been
duly authorized by all necessary regulatory and corporate or partnership action
or by its governing instrument; that this Note has been duly executed by an
authorized officer, partner or trustee and constitutes a binding obligation
enforceable against Borrower and not in violation of any law, court order or
agreement by which Borrower is bound; and that Borrower's performance is not
threatened by any pending or threatened litigation.

10 INABILITY TO DETERMINE LIBOR RATES, INCREASED COSTS, ILLEGALITY.

      a Increased Costs. If the Bank shall determine that, due to either (a) the
introduction of any change (other than any change by way of imposition of or
increase in reserve requirements included in the calculation of the LIBOR) in or
in the interpretation of any requirement of law or (b) the compliance with any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law), there shall be any increase in the
cost to the Bank of agreeing to make or making, funding or maintaining any LIBOR
Rate Loans, then Borrower shall be liable for, and shall from time to time, upon
demand therefor by the Bank and pay to the Bank such additional amounts as are
sufficient to compensate the Bank for such increased costs.

      b Inability to Determine Rates. If the Bank shall determine that for any
reason adequate and reasonable means do not exist for ascertaining LIBOR for any
requested Interest Period with respect to a proposed LIBOR Rate Loan, the Bank
will give notice of such determination to Borrower. Thereafter, the Bank may not
make or maintain LIBOR Rate Loans, as the case may be, hereunder until the Bank
revokes such notice in writing. Upon receipt of such notice, Borrower may revoke
any request for a LIBOR Rate Loan or Notice then submitted by it. If Borrower
does not revoke such notice the Bank may make, or continue the Loans, as
proposed by Borrower, in the amount specified in the applicable request
submitted by Borrower, but such Loans shall be made or continued as Base Rate
Loans instead of LIBOR Rate Loans, as the case may be.

      c Illegality. If the Bank shall determine that the introduction of any law
(statutory or common), treaty, rule, regulation, guideline or determination of
an arbitrator or of a governmental authority or in the interpretation or
administration thereof, has made it unlawful, or that any central bank or other
governmental authority has asserted that it is unlawful for the Bank to make
LIBOR Rate Loans, then, on notice thereof by the Bank to Borrower, the Bank may
suspend the making of LIBOR Rate Loans until the Bank shall have notified
Borrower that the circumstances giving rise to such determination shall no
longer exist. If the Bank shall determine that it is unlawful to maintain any
LIBOR Rate Loans, Borrower shall prepay in full all LIBOR Rate Loans then
outstanding, together with accrued interest, either on the last date of the
Interest Period thereof if the Bank may lawfully continue to maintain such LIBOR
Rate Loans to such day, or immediately, if the Bank may not lawfully continue to
maintain such LIBOR Rate Loans. If Borrower is required to prepay any LIBOR Rate
Loan immediately as set forth in this subsection, then concurrently with such
prepayment, Borrower may borrow from the Bank, in the amount of such repayment,
a Base Rate Loan.

11 MISCELLANEOUS. This Note, together with any related loan and security
agreements and guaranties, contains the entire agreement between the Bank and
Borrower with respect to the Note, and supersedes every course of dealing, other
conduct, oral agreement and representation previously made by the Bank. All
rights and remedies of the Bank under applicable law and this Note or amendment
of any provision of this Note are cumulative and not exclusive. No single,
partial or delayed exercise by the Bank of any right or remedy shall preclude
the subsequent exercise by the Bank at any time of any right or remedy of the
Bank without notice. No waiver or amendment of any provision of this Note shall
be effective unless made specifically in writing by the Bank. No course of
dealing or other conduct, no oral agreement or representation made by the Bank,
and no usage of trade, shall operate as a waiver of any right or remedy of the
Bank. No waiver of any right or remedy of the Bank shall be effective unless
made specifically in writing by the Bank. Borrower agrees that in any legal
proceeding, a copy of this Note kept in the Bank's course of business may be
admitted into evidence as an original. This Note is a binding obligation
enforceable against Borrower and its successors and assigns and shall inure to
the benefit of the Bank and its successors and assigns. If a court deems any
provision of this Note invalid, the remainder of the Note shall remain in
effect. Section headings are for convenience only. Singular number includes
plural and neuter gender includes masculine and feminine as appropriate.

12 NOTICES. Any demand or notice hereunder or under any applicable law
pertaining hereto shall be in writing and duly given if delivered to Borrower
(at its address on the Bank's records) or to the Bank (at the address on page
one and separately to the Bank officer responsible for Borrowers relationship
with the Bank). Such notice or demand shall be deemed sufficiently given for all
purposes when delivered (i) by personal delivery and shall be deemed effective
when delivered, or (ii) by mail or courier and shall be deemed effective three
(3) business days after deposit in an official depository maintained by the
United States Post Office for the collection of mail or one (1) business day
after delivery to a nationally recognized overnight courier service (e.g.,
Federal Express). Notice by e-mail is not valid notice under this or any other
agreement between Borrower and the Bank.

13 JOINT AND SEVERAL. If there is more than one Borrower, each of them shall be
jointly and severally liable for all amounts which become due under this Note
and the term "Borrower" shall include each as well as all of them.

14 GOVERNING LAW; JURISDICTION. This Note has been delivered to and accepted by
the Bank and will be deemed to be made in the State of New York. This Note will
be interpreted in accordance with the laws of the State of New York excluding
its conflict of laws rules. BORROWER HEREBY IRREVOCABLY CONSENTS TO THE
EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT IN NEW YORK STATE AND
CONSENTS THAT THE BANK MAY EFFECT ANY SERVICE OF PROCESS IN THE MANNER AND AT
BORROWER'S ADDRESS SET FORTH ABOVE FOR PROVIDING NOTICE OR DEMAND; PROVIDED THAT

INDIVIDUALLY, AGAINST ANY SECURITY OR AGAINST ANY PROPERTY OF BORROWER WITHIN
ANY OTHER COUNTY, STATE OR OTHER FOREIGN OR DOMESTIC JURISDICTION. Borrower
acknowledges and agrees that the venue provided above is the most convenient

            on which the Bank is open for business, Monday through Friday
            excluding federal holidays: except that with respect to payment by

            drawing certificate or cable, telexed, teletransmitted or other
            written demand for payment purportedly drawn under the Credit.

      (d)   "Property" means goods and merchandise and any and all related
            documents, securities, funds, choses in action, and any and all
            other forms of property, whether real, personal or mixed, and any
            right or interest therein which Applicant purchases or obtains in
            connection with the issuance of a Credit.

2.    Reimbursement for Drafts.

      (a)   Drafts in United States Currency. For each Draft which is payable in
            United States currency, Applicant will reimburse the Bank at its
            office on demand in immediately available funds:

            (1)   For each sight draft, demand or receipt, Applicant will
                  reimburse the Bank immediately on demand on the same day for
                  the entire amount paid by the Bank; or if so requested by the
                  Bank, Applicant will pay such amount in advance of payment by
                  the Bank.

            (2)   For each acceptance, Applicant will pay on demand the entire
                  amount to be paid by the Bank, not later than one Banking Day
                  prior to maturity. If the acceptance is not payable at the
                  Bank, then Applicant will pay such amount in time to reach the
                  place of payment by ordinary mail not later than one Banking
                  Day prior to maturity of the acceptance.

      (b)   Drafts in Foreign Currency. For each Draft payable in foreign
            currency, Applicant will reimburse the Bank at its office on demand
            in immediately available United States funds:

            (1)   For each sight draft, demand or receipt, Applicant will
                  reimburse the Bank in an amount equal to (A) the full amount
                  paid, computed at the Bank's selling rate of exchange in New
                  York two Banking Days prior to the date of payment of the
                  Draft for cable transfers to the place of payment in the
                  currency in which the Draft is payable, plus (B) interest at
                  the rate set forth below for each day from the date of payment
                  of the Draft until the day the Bank actually receives
                  reimbursement; or if so requested by the Bank, Applicant will
                  pay the full amount in advance of payment of the Draft.

            (2)   In the case of each acceptance, Applicant will pay the Bank
                  the entire amount to be paid by the Bank pursuant to such
                  acceptance, computed at the Bank's selling rate of exchange in
                  New York two Banking Days prior to the date of payment,
                  sufficiently in advance of maturity to enable the Bank to
                  arrange for cover to reach the place of payment not later than
                  one Banking Day prior to maturity,

            (3)   If at the time for computing payment there exists no rate of
                  exchange generally current in New York for effecting such
                  cable transfers, Applicant agrees to pay the Bank on demand an
                  amount in United States currency equal to the actual cost to
                  the Bank of settlement of the Bank's obligation to the holder
                  of the Draft, however and whenever such settlement is made by
                  the Bank, plus interest at the rate set forth below payable
                  for each day from the date of settlement to but not including
                  the date the Bank receives reimbursement in full.

      (c)   Direct Debit. Applicant authorizes the Bank to obtain such
            reimbursement and all Fees, Expenses and Cash (defined below) by
            direct debit to Applicant's deposit or investment account at the
            Bank on or before the day on which the Draft is honored.

3.    Fees and Expenses. Applicant agrees to pay to the Bank on demand the
      Bank's fees and commissions ("Fees") for each Credit at the rate
      established by the Bank from time to time, plus all otherwise unreimbursed
      charges, correspondent and transfer fees and similar expenses paid or
      incurred by the Bank in connection with delivering, negotiating, advising,
      confirming, transferring or otherwise processing a Credit or Drafts under
      a Credit ("Expenses"). Applicant shall pay interest at the rate set forth
      below on any Fees, Expenses or Costs (defined below) not paid immediately
      on demand. In addition, if the Bank's expenses for carrying a Credit
      should be increased after its issuance by an increase in a related
      risk-weighted capital or similar reserve requirement. Applicant shall
      reimburse the Bank for the cost of maintaining such additional reserves,
      computed daily at the federal funds rate.

4.    Interest. Applicant agrees that if for any reason the Bank makes payment
      under a Credit prior to the Bank's receipt of funds from Applicant or does
      not receive payment for Fees or Costs immediately on demand. Applicant
      will pay interest to the Bank on demand on the entire unpaid amount from
      the date of Bank's payment to the date on which Bank receives actual
      reimbursement, at that rate per year which is on each day 5% above the
      effective rate announced by the Bank from time to time as its prime rate.
      Interest shall be calculated on the basis of a 360-day year for the actual
      number of days in each year (365 or 366) the indebtedness is outstanding.
      It is the intent of the Bank and Applicant that interest not exceed the
      maximum legal rate. Solely to the extent necessary to prevent interest
      under this Agreement from exceeding the maximum legal rate, any amount
      that would be treated as excessive under a final judicial determination of
      applicable law shall be deemed to have been a mistake and be refunded to
      Applicant.

5.    Security Interest in Transport Documents and Deposit Account. As further
      security for the performance of all of Applicant's obligations now or
      hereafter owing to the Bank, Applicant assigns to the Bank and grants the
      Bank a continuing first security interest in all Documents and Property
<PAGE>

      delivered to the Bank in connection with a Credit, whether or not released
      in trust to Applicant in advance of reimbursement, and in any other
      property of Applicant and Account Party in the Bank's possession.
      Applicant and Account Party also acknowledge the Bank's right to set off
      against their obligations under this Agreement any other property of
      Applicant or Account Party in any capacity held by the Bank in any
      capacity. Applicant grants to the Bank a subordinate security interest in
      all collateral held by each respective Beneficiary of each Credit and
      agrees that the Bank shall be subrogated to Applicant's rights with
      respect to each Beneficiary and such collateral immediately upon payment
      of the respective Credit.

6.    Other Matters Pertaining to Credits.

      (a)   No Liability. No action or omission by the Bank or its
            correspondents in connection with a Credit, taken in good faith and
            in conformity with foreign or domestic laws, regulations or customs,
            shall create any liability on the part of the Bank to Applicant. The
            Bank shall not be responsible for any act, error, neglect or
            default, omission, insolvency or failure in business of any of its
            correspondents or of any intermediate or beneficiary bank, nor for
            any delay or omission in processing any Credit resulting from
            interruption or failure of any payment system or communications
            medium, court order, or any other cause beyond the Bank's control.
            In no event shall the Bank be liable for consequential or special
            damages.

      (b)   Indemnity. All actions and omissions of the Bank and its
            correspondents in connection with the Credit or related Drafts,
            bills of lading, warehouse receipts or other Documents or Property
            taken in good faith and in conformity with such foreign or domestic
            laws, regulations or customs as the Bank or its respective
            correspondent may deem applicable shall be binding upon Applicant.
            No such action or omission shall place the Bank or any of its
            correspondents under any liability to Applicant. Applicant agrees to
            indemnify and hold harmless the Bank and its correspondents against
            all claims, demands, losses, liabilities, costs, expenses and
            damages, including without limitation the Bank's actual attorneys'
            fees and disbursements ("Costs"), arising in connection with this
            Agreement and each Credit, with any injunction against payment of a
            Credit, or in preserving the Bank's rights or collecting
            reimbursement or negotiating and documenting a workout of
            Applicant's obligations under this Agreement.

      (c)   Payment of Drafts. Applicant understands that the Bank must accept
            or pay any Draft presented to it and dated on or before the
            expiration date of the Credit, regardless of when drawn and whether
            or not negotiated, if the Draft is accompanied by all other required
            documents and appears on its face to be in substantial compliance
            with the terms and conditions of the Credit, and is within the
            maximum stated amount of the Credit. The following terms shall apply
            unless Applicant gives instructions in writing expressly to the
            contrary prior to the Bank's issuance of a specific Credit: (1) even
            though individual or aggregate shipments exceed the quantity called
            for in the Credit, the Bank may honor related Drafts up to the
            maximum stated amount of the Credit; (2) Insurance for Property
            under a commercial Credit need not exceed the maximum stated amount
            of the Credit; and (3) the Bank may honor any Drafts or other
            documents otherwise in order signed or issued by an administrator,
            executor, trustee in bankruptcy, debtor in possession, assignee,
            liquidator, receiver or other legal representative or other
            purported successor of the Beneficiary of the Credit.

      (d)   Notice of Errors. Applicant will promptly examine its copy of the
            Credit and of all amendments delivered to it from time to time by
            the Bank and will notify the Bank of any apparent errors in writing
            within one day of receipt of such documents. Absent such notice,
            Applicant shall be conclusively deemed to have waived all claims
            against the Bank and its correspondents with respect to the form of
            the Credit.

      (e)   Waiver of Discrepancies. If the Bank determines that a Draft or
            accompanying documents appear on their face not to be in compliance
            with the terms and conditions of the Credit, the Bank may in its
            sole judgment approach the Applicant for a waiver of the
            discrepancies. Applicant will make its decision known to the Bank
            within one business day of receipt of the Bank's inquiry, or sooner
            if necessary to enable the Bank to timely pay rather than reject the
            Draft. If Applicant such waived discrepancies Applicant will remain
            bound by the terms of this Agreement.

      (f)   Amendments. If a Credit is amended, modified or changed in any
            respect with Applicant's consent, or if a preadvice is issued at
            Applicant's direction, Applicant shall be bound by the terms of this
            Agreement with respect to the respective Credit: If the amendment
            increases the liability of the Bank, Applicant shall be bound as of
            the date of issuance of the amendment: if the amendment decreases
            the liability of the Bank, Applicant's liability shall be decreased
            only as of the date the Beneficiary consents to the amendment.

      (g)   Independence of Credit. Neither the Bank nor any of its
            correspondents shall be responsible for: (1) any use which may be
            made of the Credit or for any acts or omissions of any users of the
            Credit; (2) the existence, character, quality, quantity, condition,
            packing or value of any Property; (3) the time, place, manner,
            order, delay, default or omission of notice in connection with the
            shipment of any Property or Documents; (4) the validity, sufficiency
            or genuineness of documents or endorsements; (5) the character,
            adequacy or validity of any insurance concerning the Property; (6)
            the solvency, responsibility or relationship to the Property of any
            party issuing any Documents; (7) failure of any instrument to bear
            adequate reference to the Credit, failure of Documents to accompany
            any instrument at negotiation, or failure of any person to note the
            amount of any instrument on the reverse of the Credit or to
            surrender or take up the Credit or to forward Documents apart from
            the instrument as required by the terms of the Credit, each of which
            requirements may be waived by the Bank; or (8) errors, omissions,
            interruptions or delays in delivery of any messages, whether by
            mail, teletransmission or otherwise, and whether or not encrypted.

      (h)   Insurance. Applicant shall provide evidence that it maintains
            insurance covering the Property in amounts, against risks and
            provided by companies satisfactory to the Bank and shall assign the
            policies of insurance to the Bank or name the Bank as additional
            insured and loss payee, as appropriate, at the Bank's option. Absent
            such insurance, the Bank may obtain insurance at Applicant's
            expense.

7.    Additional Covenants. Applicant represents, warrants and agrees that so
      long as this Agreement is in effect:

      (a)   Authorization. Applicant is and will remain duly organized and
            existing in the jurisdiction of its organization and authorized to
            do business in all jurisdictions material to the conduct of its
            business. Applicant has the power and capacity and has taken all
            corporate or partnership action necessary to authorize Applicant to
            execute and deliver and perform its obligations under this
            Agreement. Applicant will not change its ownership or form of
            authorization without (i) obtaining the prior written consent of the
            Bank; and (ii) posting cash collateral equal to the aggregate amount
            of all outstanding Credits plus interest at the Bank's announced
            prime rate from the date of change to the expiration date of each
            respective Credit.

      (b)   Financial Records. Applicant will furnish financial statements and
            information satisfactory to the Bank upon request. Applicant will
            keep accurate and complete books and records, expressly including
            all records required pursuant to currency and trade regulations as
            in effect from time to time.

      (c)   No Liens. Applicant will not enter into any security agreement or
            permit to be filed in any public office any financing statement
            naming Applicant as debtor which creates a security interest in or
            blanket lien on any of Applicant's Documents or Property or
            after-acquired Property without Bank's prior written consent unless
            Bank is the secured party.

      (d)   Legality. The transactions covered by each Credit are not prohibited
            under the Foreign Assets Control Regulations of the United States
            Treasury Department, the Internal Revenue Code of 1986, as amended
            from time to time, the Export Administration Act of 1977, as
            amended, or related laws and regulations thereunder. Any transfer of
            monies or importation covered by the Credit shall conform in every
            respect with all applicable federal and State laws and foreign and
            domestic government regulations. Applicant has procured all licenses
            necessary for trading and shipment of the Property and shall furnish
            all certificates as the Bank may at any time require. Applicant is
            solely responsible for the structure, contents, from and legal
            compliance and consequences of each Credit issued pursuant to
            Applicant's Instructions.

      (e)   Security Procedures. Applicant assumes all risks resulting from
            facsimile and other teletransmission of applications and Credits,
            whether or not encrypted, and undertakes to comply with all security
            procedures implemented by Bank including without limitation those to
            safeguard or authenticate facsimile and other teletransmission and
            other electronic communication of applications and Credits and
            electronic funds transfer payment orders with respect to proceeds of
            Drafts. Applicant acknowledges receipt of notice, with respect to
            payment of Drafts to the Beneficiary of a Credit via electronic
            funds transfer, that under UCC Article 4A the originating bank, all
            intermediary banks and the Beneficiary's bank are entitled to rely
            on the Beneficiary's bank number and account number alone in making
            final payment and have no duty to discover any discrepancy between

            incompetent, is dissolved, suspends its present business, agrees to
            a merger or other absorption or to transfer or otherwise dispose of
            substantially all of its assets or makes or sends notice of a bulk

            makes an assignment for the benefit of creditors or commences or has

            misleading in any material respect (including without limitation by
            omission of any contingent or unliquidated liability or claim
            against Applicant): (6) there occurs any change in the management or
            ownership of Applicant or any Account Party which is, in the opinion

            whether or not Drafts thereunder have yet been presented. All
            obligations hereunder, whether or not mature and whether direct or
            contingent shall become immediately due and payable (A)
            automatically if Applicant or any Account Party commences or has
            commenced against it any bankruptcy or insolvency proceeding and (B)

            collateral and make it available to Bank at a place or places
            designated by Bank, and Bank may use and operate any collateral.

            collateral or similar action shall constitute reasonable notice if
            mailed by regular or certified mail, postage prepaid, at least five

            Bank of any right or remedy shall preclude full and timely exercise
            by the Bank at any time of any other right or remedy of the Bank
            without notice or of the same right or remedy at any other time. No
            course of dealing or other conduct, no oral agreement or
            representation made by the Bank or usage of trade shall operate as a
            waiver of any right or remedy of the Bank. No waiver shall be
            effective unless made specifically in writing by the Bank.

      (b)   Binding Obligation. This Agreement is binding on Applicant and its

            benefit of the Bank and its successors and assigns. If Applicant
            includes more than one person, their obligations hereunder shall be
            joint and several. If a third party executes an Authorization and
            Agreement of Account Party substantially in the form attached or
            other guaranty accepted by the Bank, with respect to this Agreement
            or a Credit, the obligations of Applicant and such Account Party
            shall be joint and several. If Applicant is a partnership, its
            obligations shall continue in force, notwithstanding any change in
            its membership, whether arising from the death or retirement of one
            or more partners or the accession of one or more new partners.

      (c)   Issuance of Discretionary. The Bank may decline to issue any Credit,

            if the Bank deems itself insecure with respect to reimbursement or
            upon thirty days' notice to Applicant, or (2) by Applicant upon
            actual receipt of written notice sent as provided below; provided,
            however, that Applicant's obligations under this Agreement shall
            remain in full force and effect until all amounts due and to become
            due with respect to all Credits issued or committed for prior to

            the last address of Applicant shown on the Bank's records. Applicant
            will notify Bank promptly of any change in address. Notice to the
            Bank by Applicant must be in writing, or by telephone with

            to Applicant. Credits can be amended only as provided by the UCP.

            number includes plural and neuter gender includes masculine and
            feminine as appropriate.

      (g)   Governing Law. Each Credit shall be subject to the UCP. The
            provisions herein are supplemental to and not in substitution of the
            UCP. As to matters not governed by the UCP, this Agreement shall be
            governed by the laws of the State of New York as in effect from time
            to time.

      (f)   Jurisdiction. In any action or other legal proceeding relating to
            this Note, Applicant (1) consents to the personal jurisdiction of
            any State or federal court located in the State of New York and (2)
            agrees that a copy of this Agreement, any application, any Credit,
            and Documents or any other relevant document kept in the Bank's
            course of business may be admitted into evidence as in original.

      (g)   WAIVER OF JURY TRIAL. BANK AND APPLICANT EACH WAIVE ANY RIGHT TO

a(n) |_| individual(s) |_| partnership |X| corporation |_| trust
|_| ____________________ organized under the laws of Delaware

Address of residence/chief executive office: 525 Lee Road, Rochester, New York.

BANK: MANUFACTURERS AND TRADERS TRUST COMPANY, a New York banking corporation
      with its principal banking office at One M & T Plaza, Buffalo, NY 14240.
      Attention: Office of General Counsel

Promise to Pay. For value received, Borrower promises to pay to the order of the
Bank, on the dates set forth below, the principal sum of _______________________
Dollars ($______________) (the "Principal") plus interest as agreed below and
all reasonable fees and costs (including without limitation reasonable
attorneys' fees and disbursements whether for internal or outside counsel) the
Bank incurs in order to collect any amount due under this Note, to negotiate or
document a workout or restructuring, or to preserve its rights or realize upon
any guaranty or other security for the payment of this Note ("Expenses").

Interest. The unpaid Principal of this Note shall earn interest calculated on
the basis of a 360-day year for the actual number of days of each year (365 or
366) from and including the date the proceeds of this Note were disbursed to,
but not including, the date all amounts hereunder are paid in full, at a rate
per year which shall on each day be:

|_|   ___________%.

|_|   equal to the rate in effect on that day as the rate announced by the Bank
      as its prime rate of interest.

|_|   ___________ percentage points above the rate in effect on that day as the
      rate announced by the Bank as its prime rate of interest.

If no rate is specified above, interest shall accrue at the Maximum Legal Rate
(defined below).

Maximum Legal Rate. It is the intent of the Bank and Borrower that in no event
shall interest be payable at a rate in excess of the maximum rate permitted by
applicable law (the "Maximum Legal Rate"). If this Note is for a personal loan
of less than $2,500,000 and is secured primarily by a one- to four-family
resident, the interest rate shall not exceed 16%. Solely to the extent necessary
to prevent interest under this Note from exceeding the Maximum Legal Rate, any
amount that would be treated as excessive under a final judicial interpretation
of applicable law shall be deemed to have been a mistake and automatically
canceled, and, if received by the Bank, shall be refunded to Borrower.

Default Rate. If an Event of Default (defined below) occurs, the interest rate
on the unpaid Principal shall immediately be automatically increased to 5
percentage points per year above the otherwise applicable rate per year, and any
judgment entered hereon or otherwise in connection with any suit to collect
amounts due hereunder shall bear interest at such default rate.

Repayment of Principal and Interest Late Charge. Payments shall be made in
immediately available United States funds at any banking office of the Bank.
Interest will continue to accrue until payment is actually received. If payment
is not received within five days of its due date, Borrower shall pay a late
charge equal to the greatest of (a) $50.00, (b) 5% of the delinquent amount or
(c) the Bank's then current late charge as announced from time to time. If this
Note is secured by a one- to six-family owner-occupied residence, the late
charge shall equal 2% of the delinquent amount and shall be payable if payment
is not received within fifteen days of its due date. Payments may be applied in
any order in the sole discretion of the Bank but, prior to default, shall be
applied first to past due interest, Expenses, late charges and principal, then
to current interest, Expenses, late charges and principal, and last to remaining
principal.

The Maturity Date of this Note is ________________________________,
199____/20____.

|_|   Borrower shall pay the entire Principal on the Maturity Date. In addition,
      until the outstanding Principal is paid in full, payments of all accrued
      and unpaid interest in amounts which will vary will become due and payable

      equal installments each in the amount of $_________________________ and
      ONE (1) FINAL INSTALLMENT on the Maturity Date in an amount equal to the
      outstanding Principal together with all other amounts outstanding

      expenses. In addition, until the outstanding Principal is paid in full,
      payments of all accrued and unpaid interest in amounts which will vary
      will become due and payable on the __________ day of each: |_| month |_|
      quarter |_| year commencing on _______________________________,
      199____/20____.

      |X| monthly |_| quarterly |_| annual installments consisting of both
      Principal and interest, amortized over a period of __________ years,
      commencing on _______________________________________, 199____/20____ and
      on the ____________ day of each |_| month |_| quarter |_| year thereafter
      consisting of ___________ equal installments of Principal and interest
      each in the amount of $_________________________ and ONE (1) FINAL
      INSTALLMENT on the Maturity Date in an amount equal to the outstanding
      Principal together with all other amounts outstanding hereunder including,
      without limitation, accrued interest, costs and expenses. PLEASE NOTE THAT
      THE FINAL INSTALLMENT OF PRINCIPAL SHALL BE HIGHER THAN EXPECTED IF (1) A
      PAYMENT IS RECEIVED AFTER THE DUE DATE OR (2) THE INTEREST RATE UNDER THE
      NOTE IS A VARIABLE RATE AND THERE IS AN INCREASE IN THE INTEREST RATE
      DURING THE TERM OF THE NOTE IN THOSE SITUATIONS, MORE INTEREST WILL BE DUE
      THAN PLANNED AND LESS OF THE INSTALLMENT WILL BE APPLIED TO PRINCIPAL.

Prepayment Premium. During the term of this Note. Borrower shall have the option
of paying the Principal to the Bank in advance of the Maturity Date, in whole or
in part, at any time and from time to time upon written notice received by the
Bank at least three (3) business days


                                       1
<PAGE>

prior to making such payment; provided, however, as consideration of the
privilege of making such payment, Borrower shall pay to the Bank a premium equal
to the greater of (a) one percent (1%) of the Principal prepaid, or (b) an
amount equal to the present value of the difference between (i) the amount of
interest that would have accrued on the Principal during the remaining term of
the Note, at the interest rate set forth herein in effect on the date of
prepayment and (ii) the amount of interest that would have accrued on the
Principal during the remaining term of this Note at the Current Market Rate.
"Current Market Rate" shall mean the most recent yield on United States Treasury
Obligations adjusted to a constant maturity having a term most nearly
corresponding to the term remaining from the date of prepayment to the Maturity
Date, in effect two (2) business days prior to the prepayment date as published
by the Board of Governors of the Federal Reserve System in the Federal Reserve
Statistical Release H.15 (519), or by such other quoting service, index or
commonly available source utilized by the Bank. The present value calculation
used herein shall use the Current Market Rate as the discount rate and shall be
calculated as if each installment of the Principal had been made during the
remaining term of this Note. Each partial prepayment of the Principal shall be
applied in inverse order of maturity. Upon making any prepayment of the
Principal in whole, Borrower shall pay to the Bank all interest and Expenses
owing pursuant to this Note and remaining unpaid.

                  interest, in amounts which may vary, as follows: (i) if the
                  LIBOR Rate is the Applicable Rate, on the last day of each

                  consecutive monthly, bi-monthly or quarterly installments
                  (depending on the duration of the Interest Period selected by

                  Period that commences on the date of this Note and on last day
                  of each Interest Period thereafter consisting of __________
                  equal installments of principal each in the amount of
                  $________________________ and ONE (1) FINAL INSTALLMENT on the
                  Maturity Date in an amount equal to the Outstanding Principal

                  hereunder including, without limitation, accrued interest,
                  costs and Expense (the "Final Installment"); provided,
                  however, if the Applicable Rate is converted to the Base Rate,
                  Borrower shall pay the Outstanding Principal in consecutive
                  monthly installments commencing on the first Payment Due Day
                  after the date of such conversion and on the same Payment Due
                  Day thereafter until conversion back to the LIBOR Rate (at
                  which time Borrower shall resume the monthly, bi-monthly or
                  quarterly installments in the amount set forth above or as
                  otherwise agreed to by the Bank and Borrower in writing) or
                  the Maturity Date (at which time Borrower shall pay the Final
                  Installment) with each such installment being equal in an
                  amount to fully amortize the Outstanding Principal amount of
                  the Note in full by the Maturity Date or such other date
                  agreed to by the Bank and Borrower in writing. The
                  determination by the Bank of the foregoing amount shall, in
                  the absence of manifest error, be conclusive and binding upon
                  Borrower. In addition, until the Outstanding Principal is paid
                  in full, Borrower shall pay all accrued and unpaid interest,
                  in amounts which may vary, as follows: (i) if the LIBOR Rate
                  is the Applicable Rate, on the last day of each Interest
                  Period, (ii) if the Base Rate is the Applicable Rate, on the
                  Payment Due Date for each month and (iii) at maturity (whether
                  by acceleration or otherwise) and, after such maturity, on
                  demand.

      e. Maximum Legal Rate. It is the intent of the Bank and Borrower that in
no event shall interest be payable at a rate in excess of the maximum rate
permitted by applicable law (the "Maximum Legal Rate"). If this Note is for a
personal loan of less than $2,500,000 and is secured primarily by a one- to
four-family resident, the interest rate shall not exceed 16%. Solely to the
extent necessary to prevent interest under this Note from exceeding the Maximum
Legal Rate, any amount that would be treated as excessive under a final judicial
interpretation of applicable law shall be deemed to have been a mistake and
automatically canceled, and, if received by the Bank, shall be refunded to
Borrower.

      f. Default Rate. If an Event of Default (defined below) occurs, the
interest rate on the unpaid Principal Amount shall immediately be automatically
increased to 5 percentage points per year above the higher of the LIBOR Rate or
the Base Rate, and any judgment entered hereon or otherwise in connection with
any suit to collect amounts due hereunder shall bear interest at such default
rate.

      g. Repayment of Principal and Interest; Late Charge. Payments shall be
made in immediately available United States funds at any banking office of the
Bank. Interest will continue to accrue until payment is actually received. If
payment is not received within five days of its due date. Borrower shall pay a
late charge equal to the greatest of (a) $50.00, (b) 5% of the delinquent amount
or (c) the Bank's then current late charge as announced from time to time. If
this Note is secured by a one- to six-family owner-occupied residence, the late
charge shall equal 2% of the delinquent amount and shall be payable if payment
is not received within fifteen days of its due date. Payments may be applied in
any order in the sole discretion of the Bank but, prior to default, shall be
applied first to past due interest, Expenses, late charges and principal, then
to current interest, Expenses, late charges and principal, and last to remaining
principal.

      h. Prepayment.

            i.    Subject to the following, during the term of this Note,
                  Borrower shall have the option of paying the Principal Amount
                  to the Bank in advance of the Maturity Date, in whole or in
                  part, at any time and from time to time upon written notice
                  received by the Bank at least three (3) business days prior to
                  making such payment. If (i) Borrower prepays, in whole or in
                  part, any Principal Amount when the Applicable Rate is the
                  LIBOR Rate before the end of the Interest Period, (ii) there
                  occurs an Event of Default or the Applicable Rate is converted
                  from the LIBOR Rate to the Base Rate before the end of an
                  Interest Period pursuant to Section 3, then Borrower shall be
                  liable for and shall pay the Bank, on demand, the higher of
                  $250.00 or the actual amount of the liabilities, expenses,
                  costs or funding losses that are a direct or indirect result
                  of such prepayment (based on the entire Principal Amount
                  pre-paid), failure to draw, early termination of the Interest
                  Period, revocation, bankruptcy or otherwise. The determination
                  by the Bank of the foregoing amount shall, in the absence of
                  manifest error, be conclusive and binding upon Borrower.

            ii.   Upon making any prepayment of the Principal Amount in whole,
                  Borrower shall pay to the Bank all interest and Expenses owing
                  pursuant to the Note and remaining unpaid. Each partial
                  prepayment of the Principal Amount shall be applied in inverse
                  order of maturity to the principal included in the
                  installments provided herein.

            iii.  In the event the Maturity Date is accelerated following an
                  Event of Default by Borrower, any tender of payment of the
                  amount necessary to satisfy the entire indebtedness made after
                  such Event of Default shall be expressly deemed a voluntary
                  prepayment. In such a case, to the extent permitted by law,
                  the Bank shall be entitled to the amount necessary to satisfy
                  the entire indebtedness, plus the appropriate prepayment
                  premium calculated in accordance with this Section 2(h).

5. EVENTS OF DEFAULT; ACCELERATION. The following constitute an event of default
("Event of Default"): (i) failure by Borrower to make any payment when due
(whether at the stated maturity, by acceleration or otherwise) of the amounts
due under this Note, or any part thereof, or there occurs any event or condition
which after notice, lapse of time or both will permit such acceleration. See
Addendum Insert No. 2.

6. RIGHT OF SETOFF. The Bank shall have the right to set off against the amounts
owing under this Note any property held in a deposit or other account with the
Bank or any Affiliate or otherwise owing by the Bank or any Affiliate in any
capacity to Borrower or any guarantor or endorser of this Note. Such set-off
shall be deemed to have been exercised immediately at the time the Bank or such
Affiliate elect to do so.

7. INABILITY TO DETERMINE LIBOR RATES, INCREASED COSTS, ILLEGALITY.

      a. Increased Costs. If the Bank shall determine that, due to either (a)
the introduction of any change (other than any change by way of imposition of or
increase in reserve requirements included in the calculation of the LIBOR) in or
in the interpretation of any requirement of law or (b) the compliance with any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law), there shall be any increase in the
cost to the Bank of agreeing to make or making, funding or maintaining any loans
based on LIBOR, then Borrower shall be liable for, and shall from time to time,
upon demand therefor by the Bank and pay to the Bank such additional amounts as
are sufficient to compensate the Bank for such increased costs.

      b. Inability to Determine Rates. If the Bank shall determine that for any
reason adequate and reasonable means do not exist for ascertaining LIBOR for the
Interest Period specified above, the Bank will give notice of such determination
to Borrower. Thereafter, the Bank may not maintain the loan hereunder at the
LIBOR Rate until the Bank revokes such notice in writing and, until such
revocation, the Bank may convert the Applicable Rate from the LIBOR Rate to the
Base Rate.

      c. Illegality. If the Bank shall determine that the introduction of any
law (statutory or common), treaty, rule, regulation, guideline or determination
of an arbitrator or of a governmental authority or in the interpretation or
administration thereof, has made it unlawful, or that any central bank or other
governmental authority has asserted that it is unlawful for the Bank to make
loans at based on LIBOR then, on notice thereof by the Bank to Borrower, the
Bank may suspend the maintaining of the loan hereunder at the LIBOR Rate until
the Bank shall have notified Borrower that the circumstances giving rise to such
determination shall no longer exist. If the Bank shall determine that it is
unlawful to maintain the loan hereunder based on LIBOR, the Bank may convert the
Applicable Rate from the LIBOR Rate to the Base Rate.

                           DATED AS OF _____ EXECUTED
                              BY CVC PRODUCTS, INC.
                                   IN FAVOR OF
                     MANUFACTURERS AND TRADERS TRUST COMPANY

      This ADDENDUM to a certain LIBOR Term Note, dated ________, is made by CVC
PRODUCTS, INC. ("Borrower") in favor of MANUFACTURERS AND TRADERS TRUST COMPANY
("Bank"). This Rider is an integral part of the LIBOR Term Note.

Insert No. 1

      a.    Election. Borrower may, upon irrevocable request to the Bank,

            i.    elect to convert on any Business Day the interest rate from
                  the Base Rate into a LIBOR Rate provided the amount converted
                  is not less than the minimum borrowing amount required under
                  the Loan Agreement; or

            ii.   elect to convert the interest rate from a LIBOR Rate as of the
                  last day of the applicable Interest Period to a Base Rate; or

            iii.  elect to continue (subject to the minimum borrowing amount
                  limitation) any LIBOR Rate as of the last day of the Interest
                  Period applicable to such LIBOR Rate with the same or
                  different Interest Period.

      b.    Notice of Conversion/Continuation.

            i.    For an election under Section 3(a)(i) or 3(a)(iii), Borrower
                  must deliver to the Bank by 2:00 p.m. (Eastern Standard Time)
                  on a Business Day a Notice of Conversion ("Notice of
                  Conversion") for an election under Section 3(a)(i) or a
                  Notice of Continuation ("Notice of Continuation") for an
                  election under Section 3(a)(iii) specifying the duration of
                  the requested Interest Period (i.e., 1, 2, 3 or 6 month
                  Interest Period).

            ii.   The Continuation Date or Conversion Date (as the case may be)
                  shall be the later of (A) two (2) Business Days from the
                  Business Day the Bank receives the Notice of Conversion or
                  Notice of Continuation (either, a "Notice") in accordance with
                  the foregoing Section or (B) the last day of the relevant
                  Interest Period if a Notice is received by the Bank more than
                  two (2) Business Days before the last day of an Interest
                  Period. If a Notice is received after 2:00 p.m. (Eastern
                  Standard Time), the Notice will be deemed to have been
                  received on the next Business Day. Notice of Continuation
                  received more than two (2) Business Days before the end of an
                  Interest Period shall be deemed to have been received two (2)
                  Business Days before the end of such Interest Period for
                  purposes of determining the LIBOR Rate for the next Interest
                  Period. Accordingly, if, for example, Borrower has a LIBOR
                  Rate Loan with a one month Interest Period ending on June 15
                  and wants to continue the LIBOR Rate Loan with a two month
                  Interest Period, Borrower must deliver its Notice of
                  Continuation identifying the new two month Interest Period to
                  the Bank by 2:00 p.m. (Eastern Standard Time) on June 13
                  (provided that June 13 and June 14 are Business Days).
<PAGE>

            iii.  For an election under Section 3(a)(ii), Borrower may deliver
                  to the Bank a Notice of Conversion at any time during an
                  Interest Period up to the last day of such Interest Period or
                  may have the LIBOR Rate automatically convert to a Base Rate
                  pursuant to Section 3(c). Any such Notice of Conversion
                  delivered during an Interest Period shall be effective on the
                  last day of the Interest Period.

            iv.   The Bank may take action on any Notice in reliance upon any
                  oral, telephonic, written or teletransmitted Notice that the
                  Bank in good faith believes to be valid and to have been made
                  by Borrower or on behalf of Borrower. No Notice may be
                  delivered by e-mail. The Bank shall incur no liability to
                  Borrower or to any other person as a direct or indirect result
                  of acting on any Notice under this Note. The Bank, in its sole
                  discretion, may reject any Notice that is incomplete.

      c. Expiration of Interest Period. If Borrower does not submit a Notice of
Continuation in accordance with Section 3(b)(i) and 3(b)(ii) so that the Bank
receives the Notice of Continuation at least two (2) Business Days before the
end of an Interest Period, the LIBOR Rate shall automatically be converted into
a Base Rate and this Note shall accrue interest at the Base Rate until two (2)
Business Days after the Bank receives a Notice of Conversion pursuant to Section
3(b)(i) and 3(b)(ii) electing to convert the Note from a Base Rate to a LIBOR
Rate pursuant to Section 3(a)(i). A Notice of Continuation received one (1)
Business Day before the end of an Interest Period will not effect a continuation
of a LIBOR Rate. Rather, such LIBOR Rate shall automatically convert to a Base
Rate on the last day of the Interest Period. The late Notice of Continuation,
however, will be deemed to be a Notice of Conversion that will be effective two
(2) Business Days from the date received by the Bank.

      d. Conversion upon Default. Unless the Bank shall otherwise consent in
writing, if (i) Borrower has failed to pay when due, in whole or in part, the
indebtedness under the Note (whether by demand or otherwise), or (ii) there
exists a condition or event which with the passage of time, the giving of notice
or both shall constitute an event of default under any of Borrower's agreement
with the Bank, if any, Borrower may not elect to convert or continue a LIBOR
Rate. Further, the Bank, in its sole discretion, may (i) permit any outstanding
LIBOR Rate to continue until the last day of the applicable Interest Period at
which time such LIBOR Rate shall automatically be converted into a Base Rate or
(ii) convert any outstanding LIBOR Rate into a Base Rate before the end of the
applicable Interest Period applicable to such LIBOR Rate. Notwithstanding the
foregoing, if Borrower commences, or has commenced against it, any proceeding or
request for relief under any bankruptcy, insolvency or similar laws now or
hereafter in effect in the United States of America or any state or territory
thereof or any foreign jurisdiction or any formal or informal proceeding for the
dissolution or liquidation of, settlement of claims against or winding up of
affairs of Borrower (a "Bankruptcy Event"), any outstanding LIBOR Rate shall be
automatically converted to Base Rate without further action by the Bank and
Borrower's rights to have Base Rate converted under Section 3 shall be
automatically terminated. Nothing herein shall be construed to be a waiver by
the Bank to have this Note accrue interest at the Default Rate of interest
(which shall be calculated from the higher of the LIBOR Rate or the Base Rate)
or the right of the Bank to the amounts set forth in Section 2(a) of this Note.

      Insert No. 2

      or (b) any Event of Default occurs under the Loan Agreement, as the Loan
Agreement is amended, extended or replaced from time to time.

      As used in this Note (i) "any agreement with the Bank" includes any
agreement, note or instrument with the Bank (which includes, without limitation,
the Loan Agreement, the 1999 Term Note, the 1999 Grid Note, the Existing Bank
Documents and the Loan Documents); (ii) "accelerated" or "acceleration" means
indebtedness that becomes due at maturity, by notice after the occurrence of an
Event of Default or which becomes due as a result of a demand. All defined terms
in the Loan Agreement shall have the same meaning herein unless otherwise
defined herein.

      Automatically upon the commencement of Borrower's or any Guarantor's
bankruptcy if voluntary and upon lapse of forty-five (45) days without dismissal
if involuntary, all amounts outstanding hereunder shall become immediately due
and payable. Upon the occurrence of any other Event of Default hereunder, at the
Bank's option, all amounts hereunder shall become immediately due and payable.

      IN WITNESS WHEREOF, Borrower has executed and unconditionally delivered
this Addendum together with the preprinted form of this Note on the date
indicated in the acknowledgement, effective as of _______.

to the extent permitted under applicable law, purchase or license the whole or
any part of the Patent Collateral or interests therein sold, licensed or
otherwise disposed of.

9.    COLLATERAL PROTECTION.

      If the Assignors shall fail to do any act that they have covenanted to do
hereunder, or if any representation or warranty of the Assignors shall be
breached, the Bank, in their own name or that of the Assignors (in the sole
discretion of the Bank), may (but shall not be obligated to) after ten (10) days
written notice do such act or remedy such breach (or cause such act to be done
or such breach to be remedied), and the Assignors agree promptly to reimburse
the Bank for any cost or expense incurred by the Bank in so doing.

10.   POWER OF ATTORNEY.

      If any Event of Default shall have occurred and be continuing, the
Assignors do hereby make, constitute and appoint the Bank (and any officer or
agent of the Bank as the Bank may select in its exclusive discretion) as the
Assignors' true and lawful attorney-in-fact, with the power to endorse the
Assignors' name on all applications, documents, papers and instruments necessary
for the Bank to use any of the Patent Collateral, to practice, make, use or sell
the inventions disclosed or claimed in any of the Patent Collateral, to grant or
issue any exclusive or nonexclusive license of any of the Patent Collateral to
any third person, or necessary for the Bank to assign, pledge, convey or
otherwise transfer title in or dispose of the Patent Collateral or any part
thereof or interest therein to any third person, and, in general, to execute and
deliver any instruments or documents and do all other acts which the Assignors
are obligated to execute and do hereunder. The Assignors hereby ratify all that
such attorney shall lawfully do or cause to be done by virtue hereof, and
releases the Bank from any claims, liabilities, causes of action or demands
arising out of or in connection with any action taken or omitted to be taken by
the Bank under this power of attorney (except for the Bank's gross negligence or
willful misconduct). This power of attorney shall be irrevocable for the
duration of this Patent Agreement.

11.   FURTHER ASSURANCES.

      The Assignors shall, at any time and from time to time, and at their

consents of third parties), as the Bank may request or as may be necessary or
appropriate in order to implement and effect fully the intentions, purposes

the grant, perfection and priority of the Bank's security interest in any of the
Patent Collateral.

12.   TERMINATION.

      At such time as all of the Obligations have been finally paid and
satisfied in full and neither of the Assignors have any right to request
advances from Bank under a line of credit, this Patent Agreement shall terminate
and the Bank shall, upon the written request and at the expense of the
Assignors, execute and deliver to the Assignors all deeds, assignments and other
instruments as may be necessary or proper to reassign and reconvey to and
re-vest in the Assignors the entire right, title and interest to the Patent
Collateral previously granted, assigned, transferred and conveyed to the Bank by
the Assignors pursuant to this Patent Agreement, as fully as if this Patent
Agreement had not been made, subject to any disposition of all or any part
thereof which may have been made by the Bank pursuant hereto or the Security
Agreements.

13.   COURSE OF DEALING.

      No course of dealing among the Assignors, and the Bank, nor any failure to
exercise, nor any delay in exercising, on the part of the Bank, any right, power
or privilege hereunder or under the Security Agreements shall operate as a
waiver thereof; nor shall any single or partial exercise of any right, power or
privilege hereunder or thereunder preclude any other or further exercise thereof
or the exercise of any other right, power or privilege.

14.   EXPENSES.

      Any and all reasonable fees, costs and expenses, of whatever kind or

Assignors.

other agreements or by law, shall be cumulative and may be exercised singularly

Agreements, and nothing contained herein shall in any way derogate from any of
the rights or remedies of the Bank contained therein. Nothing contained in this

19.   AMENDMENT AND WAIVER.

      This Patent Agreement is subject to modification only by a writing signed
by the Bank and the Assignors, except as provided in Section 5.2. The Bank shall
not be deemed to have waived any right hereunder unless such waiver shall be in
writing and signed by the Bank. A waiver on any one occasion shall not be
construed as a bar to or waiver of any right on any future occasion.

20.   GOVERNING LAW; CONSENT TO JURISDICTION.

      THIS PATENT AGREEMENT IS INTENDED TO TAKE EFFECT AS A SEALED INSTRUMENT
AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE

21.   WAIVER OF JURY TRIAL.

      THE ASSIGNORS WAIVE THEIR RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION
OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS PATENT AGREEMENT,
ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR
OBLIGATIONS. Except as prohibited by law, the Assignors waive any right which
they may have to claim or recover in any litigation referred to in the preceding
sentence any special, exemplary, punitive or consequential damages or any
damages other than, or in addition to, actual damages. The Assignors (i) certify
that neither the Bank nor any representative, agent or attorney of the Bank has
represented, expressly or otherwise, that the Bank would not, in the event of
litigation, seek to enforce the foregoing waivers, and (ii) acknowledges that,
in entering into the Loan Agreement and the other agreements, notes, instruments
and documents executed in connection therewith to which the Bank is a party, the

contained in this Section 21.

22.   BANK'S RIGHT TO ACCEPT OR CONSENT, ETC.

      Notwithstanding anything herein to the contrary, Bank shall not be deemed
to have unreasonably delayed in responding to a request for a consent hereunder
or the approval of a counsel proposed by Assignors whom the Bank must consent to
unless Bank fails to


                                      -11-
<PAGE>

respond to a request for such consent or acceptance of proposed counsel for ten
(10) days after such request is submitted and Assignors, thereafter notify Bank
in writing that they believe Bank has unreasonably delayed in responding to such
request and Bank continues for more than ten (10) days after its receipt of such
notice to respond to such request. In any event, the sole remedy for Assignors
if Bank unreasonably delayed in responding to any such request shall be that it
loses its right to consent to any such action or to approve any such counsel.

23.   MISCELLANEOUS.

      The headings of each section of this Patent Agreement are for convenience
only and shall not define or limit the provisions thereof. This Patent Agreement
and all rights and obligations hereunder shall be binding upon the Assignors and
their respective successors and permitted assigns, and shall inure to the
benefit of the Bank and its successors and assigns. In the event of any
irreconcilable conflict between the provisions of this Patent Agreement and the
Loan Agreement, or between this Patent Agreement and the Security Agreements,
the provisions of the Loan Agreement or the Security Agreements, as the case may
be, shall control. If any term of this Patent Agreement shall be held to be
invalid, illegal or unenforceable, the validity of all other terms hereof shall
in no way be affected thereby, and this Patent Agreement shall be construed and
be enforceable as if such invalid, illegal or unenforceable term had not been
included herein. The Assignors acknowledge receipt of a copy of this Patent
Agreement. All obligations of the Assignors hereunder shall be joint and
several.

24.   VIOLATION OF PATENT LICENSE

      Notwithstanding anything to the contrary contained herein, Assignor is not
granting the Bank a security interest in any Patent License Rights if such a
security interest would constitute a breach of the applicable license agreement.

      IN WITNESS WHEREOF, this Patent Agreement has been executed as of the day
and year first above written.

assign, transfer, encumber or sublicense its interest in the license granted to
the Assignor in this Section 2.3, without the prior written consent of the Bank.

hereunder.

times during regular business hours.

            The Assignor shall assume full and complete responsibility for the
prosecution, defense, enforcement or any other necessary or desirable actions in
connection with the Pledged Trademarks, and shall hold the Bank harmless from
any and all costs, damages, liabilities and expenses that may be incurred by the
Bank in connection with the Bank's interest in the Pledged Trademarks or any
other action or failure to act in connection with this Trademark Agreement or
the transactions contemplated hereby. In respect of such responsibility, the
Assignor shall retain trademark counsel acceptable to the Bank. The Bank shall
not unreasonably delay in responding to any request to approve counsel proposed
by the Assignor

      7.2   Assignor's Duties, Etc.

            The Assignor shall have the right and the duty, through trademark
counsel acceptable to the Bank, to prosecute diligently any trademark
registration applications of the Trademarks pending as of the date of this
Trademark Agreement or thereafter, to preserve and maintain all rights in the
Trademarks and Trademark Registrations, including the filing of appropriate
renewal applications and other instruments to maintain in effect the Trademark
Registrations and the payment when due of all registration renewal fees and
other fees, taxes and other expenses that shall be incurred or that shall accrue
with respect to any of the Trademarks or Trademark Registrations. Any expenses
incurred in connection


                                      -7-
<PAGE>

with such applications and actions shall be borne by the Assignor. The Assignor
shall not abandon any filed trademark registration application, or any Trademark
Registration or Trademark, without the consent of the Bank, which consent shall
not be unreasonably withheld.

      7.3   Assignor's Enforcement Rights.

            The Assignor shall have the right and the duty to bring suit or
other action in the Assignor's own name to maintain and enforce the Trademarks,
the Trademark Registrations and the Trademark Rights. The Assignor may require
the Bank to join in such suit or action as necessary to assure the Assignor's
ability to bring and maintain any such suit or action in any proper forum if
(but only if) the Bank is completely satisfied that such joinder will not
subject the Bank to any risk of liability. The Assignor shall promptly, upon
demand, reimburse and indemnify the Bank for all damages, costs and expenses,
including legal fees, incurred by the Bank pursuant to this Section 7.3.

      7.4   Protection of Trademarks, Etc.

            In general, the Assignor shall take any and all such actions
(including institution and maintenance of suits, proceedings or actions) as may
be necessary or appropriate to properly maintain, protect, preserve, care for
and enforce the Pledged Trademarks. The Assignor shall not take or fail to take
any action, nor permit any action to be taken or not taken by others under its
control, that would adversely affect the validity, grant or enforcement of the
Pledged Trademarks.

      7.5   Notification by Assignor.

            Promptly upon obtaining knowledge thereof, the Assignor will notify
the Bank in writing of the institution of, or any final adverse determination
in, any proceeding in the PTO or any similar office or agency of the United
States or any foreign country, or any court, regarding the validity of any of
the Trademarks or Trademark Registrations or the Assignor's rights, title or
interests in and to the Pledged Trademarks.

8.    REMEDIES.

      Upon the occurrence and during the continuance of an Event of Default, the
Bank shall have, in addition to all other rights and remedies given it by this
Trademark Agreement (including, without limitation, those set forth in Section
2.2), the Loan Agreement, the Security Agreement and all of the other
agreements, instruments and documents executed by the Assignor with or in favor
of the Bank at any time, those allowed by law and the rights and remedies of a
secured party under the Uniform Commercial Code as enacted in the State of New
York, and, without limiting the generality of the foregoing, the Bank may
immediately, without demand of performance and without other notice (except as
set forth next below) or demand whatsoever to the Assignor, all of which are
hereby expressly waived, sell or license at public or private sale or otherwise
realize upon the whole or from time to time any part of the Pledged Trademarks,
or any


                                      -8-
<PAGE>

interest that the Assignor may have therein, and after deducting from the
proceeds of sale or other disposition of the Pledged Trademarks all reasonable
expenses incurred by the Bank in attempting to enforce this Trademark Agreement
(including all reasonable expenses for broker's fees and legal services), shall
apply the residue of such proceeds toward the payment of the Obligations as set
forth in or by reference in the Security Agreement. Notice of any sale, license
or other disposition of the Pledged Trademarks shall be given to the Assignor at
least five (5) days before the time that any intended public sale or other
public disposition of the Pledged Trademarks is to be made or after which any
private sale or other private disposition of the Pledged Trademarks may be made,
which the Assignor hereby agrees shall be reasonable notice of such public or
private sale or other disposition. At any such sale or other disposition, the
Bank may, to the extent permitted under applicable law, purchase or license the
whole or any part of the Pledged Trademarks or interests therein sold, licensed
or otherwise disposed of.

9.    COLLATERAL PROTECTION.

      If the Assignor shall fail to do any act that it has covenanted to do
hereunder, or if any representation or warranty of the Assignor shall be
breached, the Bank, in its own name or that of the Assignor (in the sole
discretion of the Bank), may (but shall not be obligated to) after ten (10) days
written notice do such act or remedy such breach (or cause such act to be done
or such breach to be remedied), and the Assignor agrees promptly to reimburse
the Bank for any cost or expense incurred by the Bank in so doing.

10.   POWER OF ATTORNEY

      If any Event of Default shall have occurred and be continuing, the
Assignor does hereby make, constitute and appoint the Bank (and any officer or
agent of the Bank as the Bank may select in its exclusive discretion) as the
Assignor's true and lawful attorney-in-fact, with full power of substitution and
with the power to endorse the Assignor's name on all applications, documents,
papers and instruments necessary for the Bank to use the Pledged Trademarks, or
to grant or issue any exclusive or nonexclusive license of any of the Pledged
Trademarks to any third person, or to take any and all actions necessary for the
Bank to assign, pledge, convey or otherwise transfer title in or dispose of any
of the Pledged Trademarks or any interest of the Assignor therein to any third
person, and, in general, to execute and deliver any instruments or documents and
do all other acts that the Assignor is obligated to execute and do hereunder.
The Assignor hereby ratifies all that such attorney shall lawfully do or cause
to be done by virtue hereof and releases the Bank from any claims, liabilities,
causes of action or demands arising out of or in connection with any action
taken or omitted to be taken by the Bank under this power of attorney (except
for the Bank's gross negligence or willful misconduct). This power of attorney
is coupled with an interest and shall be irrevocable for the duration of this
Trademark Agreement.


                                      -9-
<PAGE>

11.   FURTHER ASSURANCES.

      The Assignor shall, at any time and from time to time, and at its expense,
make, execute, acknowledge and deliver, and file and record as necessary or
appropriate with governmental or regulatory authorities, agencies or offices,
such agreements, assignments, documents and instruments, and do such other and
further acts and things (including, without limitation, obtaining consents of
third parties), as the Bank may request or as may be necessary or appropriate in
order to implement and effect fully the intentions, purposes and provisions of
this Trademark Agreement, or to assure and confirm to the Bank the grant,
perfection and priority of the Bank's security interest in the Pledged
Trademarks.

12.   TERMINATION.

      At such time as all of the Obligations have been finally paid and
satisfied in full and the Assignor does not have any rights to request an
advance under any line of credit and all lines of credit provided by Bank have
been terminated, this Trademark Agreement shall terminate and the Bank shall,
upon the written request and at the expense of the Assignor, execute and deliver
to the Assignor all deeds, assignments and other instruments as may be necessary
or proper to reassign and reconvey to and re-vest in the Assignor the entire
right, title and interest to the Pledged Trademarks previously granted,
assigned, transferred and conveyed to the Bank by the Assignor pursuant to this
Trademark Agreement, as fully as if this Trademark Agreement had not been made,
subject to any disposition of all or any part thereof that may have been made by
the Bank pursuant hereto or the Security Agreement.

13.   COURSE OF DEALING.

      No course of dealing between the Assignor and the Bank, nor any failure to
exercise, nor any delay in exercising, on the part of the Bank, any right, power
or privilege hereunder or under the Security Agreement or any other agreement
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right, power or privilege hereunder or thereunder preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.

14.   EXPENSES.

      Any and all reasonable fees, costs and expenses, of whatever kind or
nature, including the reasonable attorneys' fees and expenses incurred by the
Bank in connection with the preparation of this Trademark Agreement and all
other documents relating hereto, the consummation of the transactions
contemplated hereby or the enforcement hereof, the filing or recording of any
documents (including all taxes in connection therewith) in public offices, the
payment or discharge of any taxes, counsel fees, maintenance or renewal fees,
encumbrances, or otherwise protecting, maintaining or preserving the Pledged
Trademarks, or in defending or prosecuting any actions or proceedings arising
out of or related to the Pledged Trademarks shall be borne and paid by the
Assignor.


                                      -10-
<PAGE>

15.   OVERDUE AMOUNTS.

      Until paid, all amounts due and payable by the Assignor hereunder shall be
a debt secured by the Pledged Trademarks and other Collateral and shall bear,
whether before or after judgment, interest at the rate of interest for overdue
principal set forth in the applicable notes evidencing such Obligations.

16.   NO ASSUMPTION OF LIABILITY; INDEMNIFICATION.

      NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, THE BANK
ASSUMES NO LIABILITIES OF THE ASSIGNOR WITH RESPECT TO ANY CLAIM OR CLAIMS
REGARDING THE ASSIGNOR'S OWNERSHIP OR PURPORTED OWNERSHIP OF, OR RIGHTS OR
PURPORTED RIGHTS ARISING FROM, ANY OF THE PLEDGED TRADEMARKS OR ANY USE, LICENSE
OR SUBLICENSE THEREOF, WHETHER ARISING OUT OF ANY PAST, CURRENT OR FUTURE EVENT,
CIRCUMSTANCE, ACT OR OMISSION OR OTHERWISE. ALL OF SUCH LIABILITIES SHALL BE
EXCLUSIVELY THE RESPONSIBILITY OF THE ASSIGNOR, AND THE ASSIGNOR SHALL INDEMNIFY
THE BANK FOR ANY AND ALL COSTS, EXPENSES, DAMAGES AND CLAIMS, INCLUDING LEGAL
FEES, INCURRED BY THE BANK WITH RESPECT TO SUCH LIABILITIES.

17.   NOTICES.

      All notices and other communications made or required to be given pursuant

18.   AMENDMENT AND WAIVER.

      This Trademark Agreement is subject to modification only by a writing
signed by the Bank and the Assignor, except as provided in Section 6.2. The Bank
shall not be deemed to have waived any right hereunder unless such waiver shall
be in writing and signed by the Bank. A waiver on any one occasion shall not be
construed as a bar to or waiver of any right on any future occasion.

19.   GOVERNING LAW; CONSENT TO JURISDICTION.

            THIS TRADEMARK AGREEMENT IS INTENDED TO TAKE EFFECT AS A SEALED
INSTRUMENT AND SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF NEW YORK. The Assignor agrees that any suit for the enforcement
of this Trademark Agreement may be brought in the courts of the County of Monroe
or any federal court sitting therein and consents to the non-exclusive
jurisdiction of such court and to service of process in any such suit being made
upon the Assignor by mail at the address specified in Section 17. The Assignor
hereby waives any objection that it may now or hereafter have to the venue of
any such suit or any such court or that such suit is brought in an inconvenient
court.

20.   WAIVER OF JURY TRIAL.

      THE ASSIGNOR WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION
OR CLAIM ARISING OUT OF ANY DISPUTE IN CONNECTION WITH THIS TRADEMARK AGREEMENT,
ANY RIGHTS OR OBLIGATIONS HEREUNDER OR THE PERFORMANCE OF ANY SUCH RIGHTS OR
OBLIGATIONS. Except as prohibited by law, the Assignor waives any right which it
may have to claim or recover in any litigation referred to in the preceding
sentence any special, exemplary, punitive or consequential damages or any
damages other than, or in addition to, actual damages. The Assignor (i)
certifies that neither the Bank nor any representative, agent or attorney of the
Bank has represented, expressly or otherwise, that the Bank would not, in the
event of litigation, seek to enforce the foregoing waivers, and (ii)
acknowledges that, in entering into the Loan Agreement and the other agreements,
instruments or documents to which the Bank is a party, the Bank is relying upon,
among other things, the waivers and certifications contained in this Section 20.

21.   BANKS RIGHT TO ACCEPT OR CONSENT, ETC.

      Notwithstanding anything herein to the contrary, Bank shall not be deemed
to have unreasonably delayed in responding to a request for a consent hereunder
or the approval of a counsel proposed by Assignor whom the Bank must consent to
unless Bank fails to respond to a request for such consent or acceptance of
proposed counsel for ten (10) days after such request is submitted and Assignor
thereafter notifies Bank in writing that it believes Bank has unreasonably
delayed in responding to such request and Bank continues for more than ten (10)
days after its receipt of such notice to respond to such request. In any event,
the sole remedy for Assignor if Bank unreasonably delayed in responding to any


                                      -12-
<PAGE>

such request shall be that it loses its right to consent to any such action or
to approve any such counsel.

22.   MISCELLANEOUS.

      The headings of each section of this Trademark Agreement are for
convenience only and shall not define or limit the provisions thereof. This
Trademark Agreement and all rights and obligations hereunder shall be binding
upon the Assignor and its successors and assigns, and shall inure to the benefit
of the Bank and its successors and assigns. In the event of any irreconcilable
conflict between the provisions of this Trademark Agreement and the Loan
Agreement, or between this Trademark Agreement and the Security Agreement, the
provisions of the Loan Agreement or the Security Agreement, as the case may be,
shall control. If any term of this Trademark Agreement shall be held to be
invalid, illegal or unenforceable, the validity of all other terms hereof shall
in no way be affected thereby, and this Trademark Agreement shall be construed
and be enforceable as if such invalid, illegal or unenforceable term had not
been included herein. The Assignor acknowledges receipt of a copy of this
Trademark Agreement.

      IN WITNESS WHEREOF, this Trademark Agreement has been executed as of the
day and year first above written.

solely to the Secured Party any payment in connection therewith (including, but
not limited to, any refund of any unearned premium therefor).

      d. The Secured Party shall have the right to verify each Account, Chattel
Paper, General Intangible, Instrument, Investment Property, Document and Deposit
Account included in the Collateral in any manner or through any medium that the
Secured Party considers appropriate, whether directly with any Account Debtor or
other Person obligated with respect thereto or otherwise and whether in the name
of any Debtor or otherwise, at the sole option of the Secured Party.

      e. The Secured Party shall have the right to (i) notify each Account
Debtor and other Person obligated with respect to any Account, Chattel Paper,
General Intangible, Instrument, Investment Property or Deposit Account included

without reference to this Agreement or to any Security Interest.

      g. Upon and at any time and from time to time after the occurrence or
existence of any Event of Default:

            i. The Secured Party shall have the right to use each Fixture and
piece of Equipment included in the Collateral for the purposes of preserving any
Goods included in the Collateral, of completing any work in process included in

any Debtor, (B) take possession of, and remove from any such premises, any

and (C) remain on and use any such premises in completing any work in process
included in the Collateral or in preparing for any sale, lease or other
disposition, in selling, leasing or otherwise disposing of, or in collecting,
any of the Collateral and (C) without the payment of any compensation of any
kind, use each trademark, service mark, trade style, trade name, patent,
copyright, license, franchise and similar General Intangible included in the
Collateral to the extent of any Debtor's rights therein for the purpose of

connection with such sale or other disposition so as to comply with the
Securities Act of 1933 and (B) restrict such prospective bidders to Persons who
will agree to purchase such Investment Property for their own accounts for
investment and not with a view to distribution or resale. No such restriction or
other restriction on such sale or other disposition that the Secured Party shall
deem necessary or desirable at the sole option of the Secured Party in light of
any "blue sky" or securities statute, regulation or other law shall be deemed to
be a factor in determining such sale or other disposition to have been made in
other than a commercially reasonable manner.

distribution or similar income received by it prior thereto.

      i. The Secured Party shall apply all proceeds received by it from any
sale, lease or other disposition of, or from any collection of, any of the
Collateral or otherwise on account of any of the Collateral (including, but not
limited to, as money payable pursuant to any insurance on any Goods included in
the Collateral) first to costs and expenses described in Section 10 of this
Agreement and then to such other of the Obligations, whether due or not due as
the Secured Party shall determine at the sole option of the Secured Party.

7. Standards of Care. If any portion of the Collateral shall be transferred to
or registered in the name of the Secured Party or of any nominee of the Secured
Party or shall be in the possession or under the control of the Secured Party,
the Secured Party shall be deemed to have exercised reasonable care in the
custody or preservation of such portion of the Collateral if, subject to the
following sentence, it (a) accords such portion of the Collateral treatment
substantially equal to the treatment that it accords its own assets of a similar
nature or (b) takes such action in the custody or preservation of such action of
the Collateral as is reasonably specified in any notice delivered or sent by any
Debtor and received by it in a reasonable time to evaluate and take such action;
provided, however, that (i) any failure by the Secured Party to take such action
shall not or itself be deemed to be a failure to exercise such reasonable care
and (ii) in no event shall the Secured Party be obligated to take such action if
it determines at its sole option that doing so would or might have any adverse
effect on the value of any of the Collateral as security for the payment of the
Obligations or otherwise be inconsistent or incompatible with any provision or
purpose of this Agreement. In no event shall the Secured Party be obligated to


                                       5
<PAGE>

            ii. Each Account, Chattel Paper and General Intangible included in
the Collateral at such time is genuine, is in all respects what it purports to
be, and is enforceable in accordance with its terms against each Account Debtor
and other Person obligated with respect thereto, and each sum represented by any
Debtor to the Secured Party as owing by such Account Debtor or other Person with
respect thereto is actually and unconditionally owing by such Account Debtor or
other Person, except for any applicable normal cash discount, without any
counterclaim, setoff or defense. The aggregate sum represented at such time by
any Debtor to the Secured Party as owing by Account Debtors and other Persons
with respect to Accounts, Chattel Paper and General Intangibles included in the
Collateral is the aggregate sum actually and unconditionally owing by Account
Debtors and other Persons with respect thereto at such time, except for
applicable normal cash discounts.

      (c) Debtor represents, warrants and covenants to the Secured Party, now
and as long as this Agreement is in effect, that (i) it has assessed its
equipment (including embedded systems), software, firmware and computer systems
(including equipment or systems supplied by others or with which Debtor's
equipment and systems exchange date data) that are material to Debtor conducting
its business and/or performing operations collectively, the "Systems") to
determine whether such Systems accurately process date data from, into, and
between the twentieth and twenty-first centuries, including leap year
calculations ("Y2K Compliant"); (ii) in sufficient time before December 31,
1999, Debtor will have corrected and redeployed any non-Y2K Compliant Systems so
that all its Systems are Y2K Compliant and all System will have been tested to
confirm that they are Y2K Compliant; and (iii) the expense of correcting and
redeploying any non-Y2K Compliant Systems and all System testing, and/or the
reasonably foreseeable consequences of any System failing to be Y2K Compliant
will not have a material adverse effect on Debtor. Upon the Secured Party's
request, Debtor shall provide the Secured Party with updates on the status of
its Systems' Year 2000 readiness.

10. Expenses. Each Debtor shall pay to the Secured Party on demand each cost and
expense (including, but not limited to, if the Secured Party retains counsel for
advice, for litigation or for any other purpose, each attorney's fee and
disbursement) incurred by the Secured Party (a) in searching any public record
for, in filing or in recording in any public office, or in obtaining from any
public office any certificate relating to, any financing statement, certificate
of title, application for any certificate of title, notice of lien, instrument
of assignment or other writing relating to any of the Collateral, (b) in
performing any obligation of any Debtor pursuant to this Agreement, (c) in
taking any action pursuant to Section 5 of this Agreement, (d) in connection
with the custody or preservation of any of the Collateral or (e) in endeavoring
to (i) enforce any indebtedness, liability or obligation of any Debtor pursuant
to this Agreement, (ii) preserve or exercise any right or remedy pursuant to
this Agreement, whether against any Debtor or otherwise, (iii) preserve or
exercise any right or remedy relating to, take possession of, collect or
enforce, have registered pursuant to the Securities Act of 1933, prepare for any
sale, lease or other disposition, assign, sell, lease, exchange, convert or
otherwise transfer or dispose of, or realize upon, any of the Collateral, (iv)
obtain any information relating to any Investment Property included in the
Collateral from the issuer of such Investment Property or register any transfer
or pledge of such Investment Property with such issuer or (v) defend against any
claim, regardless of the basis or outcome thereof and whether asserted
affirmatively, as a counterclaim, setoff or defense or otherwise, asserted
against the Secured Party as a direct or indirect result of the execution and
delivery to the Secured Party of this Agreement by any of the undersigned,
except for any claim for any tax imposed by any government or political
subdivision upon any income of the Secured Party or for any interest or penalty
relating to any such tax. Secured Party reserves the right to have Debtor pay,
upon demand, administrative fee(s) in regard to any administrative action
Secured Party is required or requested to take including, without limitation,
the preparation of discharges, release, or assignments to third-parties. After
such demand for payment of any cost, expense or fee hereunder, Debtor shall pay
interest at the default rate specified in any promissory note evidencing any of
the Obligations secured hereby on the portion of such cost or expense remaining
unpaid.

11. Cumulative Nature, Nonexclusive Exercise and Waivers of Rights and Remedies.

      a. All rights and remedies of the Secured Party pursuant to this Agreement
or otherwise shall be cumulative, and no such right or remedy shall be exclusive
of any other such right or remedy.

      b. No single or partial exercise by the Secured Party of any right or
remedy pursuant to this Agreement or otherwise shall preclude any other or
further exercise thereof, or any exercise of any other such right or remedy, by
the Secured Party.

      c. No course of dealing or other conduct heretofore pursued, accepted or
acquiesced in, no course of performance or other conduct hereafter pursued,
accepted or acquiesced in, no oral or written agreement or representation

Secured Party, whether or not relied or acted upon, and no usage of trade,
whether or not relied or acted upon, shall operate as a waiver of any right or
remedy of the Secured Party pursuant to this Agreement or otherwise. No delay by
the Secured Party in exercising any such right or remedy, whether or not relied
or acted upon, shall operate as a waiver thereof or of any other such right or
remedy. No notice or demand of any kind, and no attempted but unsuccessful
notice or demand of any kind, by the Secured Party prior to exercising any such
right or remedy on any one occasion, whether or not relied or acted upon, shall
operate as a waiver of any right of the Secured Party to exercise the same or
any other such right or remedy on such or any future occasion without any notice
or demand of any kind. No waiver by the Secured Party of any such right or
remedy shall be effective unless made in a writing duly executed by the Secured
Party and specifically referring to such waiver. No waiver by the Secured Party
on any one occasion of any such right or remedy shall operate as a waiver
thereof or of any other such right or remedy on any future occasion.

            "(including but not limited to all patents and patent applications,
            rights under all licenses, trade secrets, trademarks, copyrights and
            other intellectual property of any nature or kind (collectively
            "Intellectual Property"), whether such Intellectual Property is now
            owned by the undersigned or in which the undersigned now has any

BANK:       Manufacturers and Traders Trust Company, One M&T Plaza, Buffalo, New
            York 14240 Attention: Office of General Counsel

      1. Guaranty.

            (a) Guarantor hereby unconditionally guarantees the full and prompt
payment and performance of any and all of Borrower's Obligations (as defined
below) to the Bank when due, whether at stated maturity, by acceleration or
otherwise. As used in this Guaranty, the term "Obligations" shall mean any and
all obligations, indebtedness and other liabilities of Borrower to the Bank now
or hereafter existing, of every kind and nature and all accrued and unpaid
interest thereon and all Expenses (as defined below) including without
limitation, whether such obligations, indebtedness and other liabilities (i) are
direct, contingent, liquidated, unliquidated, secured, unsecured, matured or
unmatured; (ii) are pursuant to a guaranty or surety in favor of the Bank; (iii)
were originally contracted with the Bank or with another party (including
obligations under a guaranty or surety originally in favor of such other party);
(iv) are contracted by Borrower alone or jointly with one or more other parties;
(v) are or are not evidenced by a writing; (vi) are renewed, replaced, modified
or extended; and (vii) are periodically extinguished and subsequently reincurred
or reduced and thereafter increased. Guarantor will pay or perform its
obligations under this Guaranty upon demand. This Guaranty is and is intended to
be a continuing guaranty of payment (not collection) of the Obligations
(irrespective of the aggregate amount thereof and whether or not the Obligations
from time to time exceeds the amount of this Guaranty, if limited), independent
of, in addition and without modification to, and does not impair or in any way
affect, any other guaranty, indorsement, or other agreement in connection with
the Obligations, or in connection with any other indebtedness or liability to
the Bank or collateral held by the Bank therefor or with respect thereto,
whether or not furnished by Guarantor. Guarantor understands that the Bank can
bring an action under this Guaranty without being required to exhaust other
remedies or demand payment first from other parties.

            (b) Guarantor acknowledges the receipt of valuable consideration for
this Guaranty and acknowledges that the Bank is relying on this Guaranty in
making a financial accommodation to Borrower, whether a commitment to lend,
extension, modification or replacement of, or forbearance with respect to, any
Obligation, cancellation of another guaranty, purchase of Borrower's assets, or
other valuable consideration.

      2. Continuing, Absolute, Unconditional. This Guaranty is irrevocable,
absolute, continuing, unconditional and general without any limitation. This
Guaranty is unlimited in amount unless an amount is inserted in the following
blank.

      3. Guarantor's Waivers & Authorizations.

            (a) Guarantor's obligations shall not be released, impaired or
affected in any way including by any of the following, all of which Guarantor
hereby waives (i) any bankruptcy, reorganization or insolvency under any law of
Borrower or that of any other party, or by any action of a trustee in any such
proceeding; (ii) any new agreements or obligations of Borrower or any other
party with the Bank; (iii) any adjustment, compromise or release of any
Obligations of Borrower, by the Bank or any other party; the existence or
nonexistence or order of any filings, exchanges, releases, impairment or sale
of, or failure to perfect or continue the perfection of a security interest in
any collateral for the Obligations, (iv) any failure of Guarantor to receive
notice of any intended disposition of such collateral; (v) any fictitiousness,
incorrectness, invalidity or unenforceability, for any reason, of any instrument
or other agreement which may evidence any Obligation; (vi) any composition,
extension, stay or other statutory relief granted to Borrower including, without
limitation, the expiration of the period of any statute of limitations with
respect to any lawsuit or other legal proceeding against Borrower or any person
in any way related to the Obligations or a part thereof or any collateral
therefor; (vii) any change in form of organization, name, membership or
ownership of Borrower or Guarantor; (viii) any refusal or failure of the Bank or
any other person prior to the date hereof or hereafter to grant any additional
loan or other credit accommodation to Borrower or the Bank's or any other
party's receipt of notice of such refusal or failure; (ix) any setoff, defense
or counterclaim of Borrower with respect to the obligations or otherwise
arising, either directly or indirectly, in regard to the Obligations; or (x) any
other circumstance that might otherwise constitute a legal or equitable defense
to Guarantor's obligations under this Guaranty.

            (b) The Guarantor waives acceptance, assent and all rights of notice
or demand including without limitation (i) notice of acceptance of this
Guaranty, of Borrower's default or nonpayment of any Obligation, and of changes
in Borrower's financial condition; (ii) presentment, protest, notice of protest
and demand for payment; (iii) notice that any Obligations has been incurred or
of the reliance by the Bank upon this Guaranty; and (iv) any other notice,
demand or condition to which Guarantor might otherwise be entitled prior to the
Bank's reliance on or enforcement of this Guaranty. Guarantor further authorizes
the Bank, without notice, demand or additional reservation of rights against
Guarantor and without affecting Guarantor's obligations hereunder, from time to
time: (i) to renew, refinance, modify, subordinate, extend, increase,
accelerate, or otherwise change the time for payment of, the terms of or the
interest on the Obligations or any part thereof;(ii) to accept and hold
collateral from any party for the payment of the any or all of the Obligations,
and to exchange, enforce or refrain from enforcing, or release any or all of
such collateral; (iii) to accept any indorsement or guaranty of any or all of
the Obligations or any negotiable instrument or other writing intended to create
an accord and satisfaction with respect to any or all of the Obligations; (iv)
to release, replace or modify the obligation of any indorser or guarantor, or
any party who has given any collateral for any of all of the Obligations, or any
other party in any way obligated to pay any or all of the Obligations, and to
enforce or refrain from enforcing, or compromise or modify, the terms of any
obligation of any such endorser, guarantor or party; (v) to dispose of any and
all collateral

<PAGE>

securing the Obligations in any manner as the Bank, in its sole discretion, may
deem appropriate, and to direct the order and the enforcement of any and all
indorsements and guaranties relating to the Obligations in the Bank's sole
discretion; and (vi) to determine the manner, amount and time of application of
payments and credits, if any, to be made on all or any part of the Obligations
including, without limitation, if this Guaranty is limited in amount, to make
any such application to Obligations, if any, in excess of the amount of this
Guaranty.

            (c) Notwithstanding any other provision in this Guaranty, Guarantor
irrevocably waives, without notice, any right he or she may have at law or in
equity (including without limitation any law subrogating Guarantor to the rights
of the Bank) to seek contribution, indemnification or any other form of
reimbursement from Borrower or any other obligor or guarantor of the Obligations
for any disbursement made under this Guaranty or otherwise.

      4. Termination. This Guaranty shall remain in full force and effect as to
each Guarantor until actual receipt by the Bank officer responsible for
Borrower's relationship with the Bank of written notice of Guarantor's intent to
terminate (or Guarantor's death or incapacity) plus the lapse of a reasonable
time for the Bank to act on such notice (the "Receipt of Notice"); provided,
however, this Guaranty shall remain in full force and effect thereafter until
all Obligations outstanding, or contracted or committed for (whether or not
outstanding), before such Receipt of Notice by the Bank, and any extensions,
renewals or replacements thereof (whether made before or after such Receipt of
Notice), together with interest accruing thereon after such Receipt of Notice,
shall be finally and irrevocably paid in full. Discontinuance of this Guaranty
as to one Guarantor shall not operate as a discontinuance hereof as to any other
guarantor. Payment of all of the Obligations from time to time shall not operate
as a discontinuance of this Guaranty, unless a Receipt of Notice as above
provided has been received by the Bank. Guarantor agrees that, to the extent
that Borrower makes a payment or payments to the Bank on the Obligations, or the
Bank receives any proceeds of collateral to be applied to the Obligations, which
payment or payments or any part thereof are subsequently invalidated, declared
to be fraudulent or preferential, set aside or otherwise are required to be
repaid to Borrower, its estate, trustee, receiver or any other party, including,
without limitation, under any bankruptcy law, state or federal law, common law
or equitable cause, then to the extent of such repayment, the obligation or part
thereof which has been paid, reduced or satisfied by such amount shall be
reinstated and continued in full force and effect as of the date such initial
payment, reduction or satisfaction occurred, notwithstanding any contrary action
which may have been taken by the Bank in reliance upon such payment or payments.
As of the date any payment or proceeds of collateral are returned, the statute
of limitations shall start anew with respect to any action or proceeding by the
Bank against Guarantor under this Guaranty.

      5. Expenses. Guarantor agrees to reimburse the Bank on demand for all the
Bank's expenses, damages and losses of any kind or nature, including without
limitation costs of collection and actual attorneys' fees and disbursements
whether for internal or external counsel incurred by the Bank in attempting to
enforce this Guaranty, collect any of the Obligations including any workout or
bankruptcy proceedings or other legal proceedings or appeal, realize on any
collateral, defense of any action under the prior paragraph or for any other
purpose related to the Obligations (collectively, "Expenses"). Expenses will
accrue interest at the highest default rate in any instrument evidencing the
Obligations until payment is actually received by the Bank. Guarantor shall
provide Bank with the same financial statements and other information Borrower
is required to provide to Bank under the Loan Agreement between Bank and
Borrower dated March 31, 1998, as it may be amended, extended or replaced.

      6. Financial and Other Information. Guarantor represents that its assets
are not subject to any liens, encumbrances or contingent liabilities except as
fully disclosed to the Bank in such statements. Guarantor authorizes the Bank
from time to time to obtain, verify and review all financial data deemed
appropriate by the Bank in connection with this Guaranty and the Obligations,
including without limitation credit reports from agencies. Guarantor understands
this Guaranty and has satisfied itself as to its meaning and consequences and
acknowledges that it has made its own arrangements for keeping informed of
changes or potential changes affecting the Borrower including the Borrower's
financial condition.

      7. Security; Right of Setoff. As further security for payment of the
Obligations, Expenses and any other obligations of Guarantor to the Bank,
Guarantor hereby grants to the Bank a security interest in all money, securities
and other property of Guarantor in the actual or constructive possession or
control of the Bank or its affiliates including without limitation all deposits
and other accounts owing at any time by the Bank or any of its affiliates in any
capacity to Guarantor in any capacity (collectively, "Property"). The Bank shall
have the right to set off Guarantor's Property against any of Guarantor's
obligations to the Bank. Such set-off shall be deemed to have been exercised
immediately at the time the Bank or such affiliate elect to do so. The Bank
shall also have all of the rights and remedies of a secured party under the
Uniform Commercial Code in effect in the State of New York as of the date of
this Guaranty in addition to those under this Guaranty and other applicable law
and agreements.

      8. No Transfer of Assets. Guarantor shall not transfer, reinvest or
otherwise dispose of its assets in a manner or to an extent that would or might
impair Guarantor's ability to perform its obligations under this Guaranty.

      9. Nonwaiver by the Bank; Miscellaneous. This Guaranty is intended by
Guarantor to be the final, complete and exclusive expression of the agreement
between Guarantor and the Bank. This Guaranty may be assigned by the Bank, shall
inure to the benefit of the Bank and its successors and assigns, and shall be
binding upon Guarantor and his or her legal representative, successors and
assigns and any participation may be granted by the Bank herein in connection
with the assignment or granting of a participation by the Bank in the
Obligations or any part thereof. All rights and remedies of the Bank are
cumulative, and no such right or remedy shall be exclusive of any other right or
remedy. This Guaranty does not supersede any other guaranty or security granted
to the Bank by Guarantor or others (except as to Guarantor's Waiver of
Subrogation rights above). No single, partial or delayed exercise by the Bank of
any right or remedy shall preclude exercise by the Bank at any time at its sole
option of the same or any other right or remedy of the Bank without notice.
Guarantor expressly disclaims any reliance on any course of dealing or usage of
trade or oral representation of the Bank including, without limitation,
representations to make loans to Borrower or enter into any other agreement with
Borrower or Guarantor. No course of dealing or other conduct, no oral agreement
or representation made by the Bank or usage of trade shall operate as a waiver
of any right or remedy of the Bank. No waiver or amendment of any right or
remedy of the Bank or release by the Bank shall be effective unless made
specifically in writing by the Bank. Each provision of this Guaranty shall be
interpreted as consistent with existing law and shall be deemed amended to the
extent necessary to comply with any conflicting law. If any provision
nevertheless is held invalid, the other provisions shall remain in effect.
Guarantor agrees that in any legal proceeding, a copy of this Guaranty kept in
the Bank's course of business may be admitted into evidence as an original.
Captions are solely for convenience and not part of the substance of this
Guaranty. If this Guaranty is limited pursuant to Paragraph 2 hereof, until the
Obligations are indefeasibly paid in full, the Guaranteed Amount shall not be
reduced in any manner whatsoever by any amounts which the Bank may realize
before or after maturity of the Obligations (by acceleration, demand or
otherwise), as a result of payments made by or on behalf of Borrower or by or on
behalf of any other person or entity other than Guarantor primarily or
secondarily liable for the Obligations or any part thereof, or otherwise
credited to Borrower

<PAGE>

or such person or entity, or as a result of the exercise of the Bank's rights
with respect to any collateral for the Obligations or any part thereof. Payments
made to the Bank by Guarantor (other than, directly or indirectly, from
collateral or other persons or entities liable for any portion of the
Obligations) after maturity of the Obligations, by acceleration or otherwise,
shall reduce the Guaranteed Amount.

      10. Joint and Several. If there is more than one Guarantor, each Guarantor
jointly and severally guarantees the payment and performance in full of all
obligations under this Guaranty and the term "Guarantor" means each as well as
all of them. Guarantor also agrees that the Bank need not seek payment from any
source other than the undersigned Guarantor. This Guaranty is a primary
obligation. Guarantor's obligations hereunder are separate and independent of
Borrower's, and a separate action may be brought against Guarantor whether or
not action is brought or joined against or with Borrower or any other party.

      11. Authorization. Guarantor certifies that it is an entity in the form
described above duly organized and in good standing under the laws of the State
of its organization and duly authorized to do business in each State material to
the conduct of its business. Guarantor has determined that the execution of this
Guaranty will be in its best interests, to its direct benefit, incidental to its
powers, and in furtherance of its duly acknowledged purposes and objectives.
Execution of this Guaranty by the persons signing below has been authorized by
all necessary corporate action, including directors' and shareholder consent or
(as appropriate) is authorized by its partnership agreement or governing
instrument. Guarantor's chief executive office is located at the above address.

      12. Notices. Any demand or notice hereunder or under any applicable law
pertaining hereto shall be in writing and duly given if delivered to Guarantor
(at its address on the Bank's records) or to the Bank (at the address on page
one and separately to the Bank officer responsible for Borrower's relationship
with the Bank). Such notice or demand shall be deemed sufficiently given for all
purposes when delivered (i) by personal delivery and shall be deemed effective
when delivered, or (ii) by mail or courier and shall be deemed effective three
(3) business days after deposit in an official depository maintained by the
United States Post Office for the collection of mail or one (1) business day
after delivery to a nationally recognized overnight courier service (e.g.,
Federal Express). Notice by e-mail is not valid notice under this or any other
agreement between Guarantor and the Bank.

      13. Governing Law and Jurisdiction. This Guaranty has been delivered to
and accepted by the Bank and will be deemed to be made in the State of New York.
Unless provided otherwise under federal law, this Guaranty will be interpreted
in accordance with the laws of the State of New York excluding its conflict of
laws rules. GUARANTOR HEREBY IRREVOCABLY CONSENTS TO THE EXCLUSIVE JURISDICTION
OF ANY STATE OR FEDERAL COURT IN ANY JUDICIAL DISTRICT OR COUNTY IN THE STATE OF
NEW YORK WHERE THE BANK MAINTAINS A BRANCH AND CONSENTS THAT THE BANK MAY EFFECT
ANY SERVICE OF PROCESS IN THE MANNER AND AT GUARANTOR'S ADDRESS SET FORTH ABOVE
FOR PROVIDING NOTICE OR DEMAND; PROVIDED THAT NOTHING CONTAINED IN THIS GUARANTY
WILL PREVENT THE BANK FROM BRINGING ANY ACTION, ENFORCING ANY AWARD OR JUDGMENT
OR EXERCISING ANY RIGHTS AGAINST GUARANTOR INDIVIDUALLY, AGAINST ANY SECURITY OR
AGAINST ANY PROPERTY OF GUARANTOR WITHIN ANY OTHER COUNTY, STATE OR OTHER
FOREIGN OR DOMESTIC JURISDICTION. Guarantor acknowledges and agrees that the
venue provided above is the most convenient forum for both the Bank and
Guarantor. Guarantor hereby waives (i) any objection to venue and any objection
based on a more convenient forum in any action instituted under this Guaranty;
(ii) any right to assert any counterclaim or setoff or any defense based upon a
statute of limitations, a claim of laches or of any other legal theory; and
(iii) its right to attack a final judgment that is obtained as a direct or
indirect result of any action hereunder.

      14. Waiver of Jury Trial. GUARANTOR AND THE BANK HEREBY KNOWINGLY,
VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY GUARANTOR AND
THE BANK MAY HAVE IN ANY ACTION OR PROCEEDING, IN LAW OR IN EQUITY, IN
CONNECTION WITH THIS GUARANTY OR THE TRANSACTIONS RELATED HERETO. GUARANTOR
REPRESENTS AND WARRANTS THAT NO REPRESENTATIVE OR AGENT OF THE BANK HAS
REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE BANK WILL NOT, IN THE EVENT OF
LITIGATION, SEEK TO ENFORCE THIS JURY TRIAL WAIVER. GUARANTOR ACKNOWLEDGES THAT
THE BANK HAS BEEN INDUCED TO ENTER INTO THIS GUARANTY BY, AMONG OTHER THINGS,
THE PROVISIONS OF THIS SECTION.

                                        GUARANTOR:

BANK:       Manufacturers and Traders Trust Company, One M&T Plaza, Buffalo, New
            York 14240 Attention: Office of General Counsel

      1. Guaranty.

            (a) Guarantor hereby unconditionally guarantees the full and prompt
payment and performance of any and all of Borrower's Obligations (as defined
below) to the Bank when due, whether at stated maturity, by acceleration or
otherwise. As used in this Guaranty, the term "Obligations" shall mean any and
all obligations, indebtedness and other liabilities of Borrower to the Bank now
or hereafter existing, of every kind and nature and all accrued and unpaid
interest thereon and all Expenses (as defined below) including without
limitation, whether such obligations, indebtedness and other liabilities (i) are
direct, contingent, liquidated, unliquidated, secured, unsecured, matured or
unmatured; (ii) are pursuant to a guaranty or surety in favor of the Bank; (iii)
were originally contracted with the Bank or with another party (including
obligations under a guaranty or surety originally in favor of such other party);
(iv) are contracted by Borrower alone or jointly with one or more other parties;
(v) are or are not evidenced by a writing; (vi) are renewed, replaced, modified
or extended; and (vii) are periodically extinguished and subsequently reincurred
or reduced and thereafter increased. Guarantor will pay or perform its
obligations under this Guaranty upon demand. This Guaranty is and is intended to
be a continuing guaranty of payment (not collection) of the Obligations
(irrespective of the aggregate amount thereof and whether or not the Obligations
from time to time exceeds the amount of this Guaranty, if limited), independent
of, in addition and without modification to, and does not impair or in any way
affect, any other guaranty, indorsement, or other agreement in connection with
the Obligations, or in connection with any other indebtedness or liability to
the Bank or collateral held by the Bank therefor or with respect thereto,
whether or not furnished by Guarantor. Guarantor understands that the Bank can
bring an action under this Guaranty without being required to exhaust other
remedies or demand payment first from other parties.

            (b) Guarantor acknowledges the receipt of valuable consideration for
this Guaranty and acknowledges that the Bank is relying on this Guaranty in
making a financial accommodation to Borrower, whether a commitment to lend,
extension, modification or replacement of, or forbearance with respect to, any
Obligation, cancellation of another guaranty, purchase of Borrower's assets, or
other valuable consideration.

      2. Continuing, Absolute, Unconditional. This Guaranty is irrevocable,
absolute, continuing, unconditional and general without any limitation. This
Guaranty is unlimited in amount unless an amount is inserted in the following
blank.

      3. Guarantor's Waivers & Authorizations.

            (a) Guarantor's obligations shall not be released, impaired or
affected in any way including by any of the following, all of which Guarantor
hereby waives (i) any bankruptcy, reorganization or insolvency under any law of
Borrower or that of any other party, or by any action of a trustee in any such
proceeding; (ii) any new agreements or obligations of Borrower or any other
party with the Bank; (iii) any adjustment, compromise or release of any
Obligations of Borrower, by the Bank or any other party; the existence or
nonexistence or order of any filings, exchanges, releases, impairment or sale
of, or failure to perfect or continue the perfection of a security interest in
any collateral for the Obligations, (iv) any failure of Guarantor to receive
notice of any intended disposition of such collateral; (v) any fictitiousness,
incorrectness, invalidity or unenforceability, for any reason, of any instrument
or other agreement which may evidence any Obligation; (vi) any composition,
extension, stay or other statutory relief granted to Borrower including, without
limitation, the expiration of the period of any statute of limitations with
respect to any lawsuit or other legal proceeding against Borrower or any person
in any way related to the Obligations or a part thereof or any collateral
therefor; (vii) any change in form of organization, name, membership or
ownership of Borrower or Guarantor; (viii) any refusal or failure of the Bank or
any other person prior to the date hereof or hereafter to grant any additional
loan or other credit accommodation to Borrower or the Bank's or any other
party's receipt of notice of such refusal or failure; (ix) any setoff, defense
or counterclaim of Borrower with respect to the obligations or otherwise
arising, either directly or indirectly, in regard to the Obligations; or (x) any
other circumstance that might otherwise constitute a legal or equitable defense
to Guarantor's obligations under this Guaranty.

            (b) The Guarantor waives acceptance, assent and all rights of notice
or demand including without limitation (i) notice of acceptance of this
Guaranty, of Borrower's default or nonpayment of any Obligation, and of changes
in Borrower's financial condition; (ii) presentment, protest, notice of protest
and demand for payment; (iii) notice that any Obligations has been incurred or
of the reliance by the Bank upon this Guaranty; and (iv) any other notice,
demand or condition to which Guarantor might otherwise be entitled prior to the
Bank's reliance on or enforcement of this Guaranty. Guarantor further authorizes
the Bank, without notice, demand or additional reservation of rights against
Guarantor and without affecting Guarantor's obligations hereunder, from time to
time: (i) to renew, refinance, modify, subordinate, extend, increase,
accelerate, or otherwise change the time for payment of, the terms of or the
interest on the Obligations or any part thereof;(ii) to accept and hold
collateral from any party for the payment of the any or all of the Obligations,
and to exchange, enforce or refrain from enforcing, or release any or all of
such collateral; (iii) to accept any indorsement or guaranty of any or all of
the Obligations or any negotiable instrument or other writing intended to create
an accord and satisfaction with respect to any or all of the Obligations; (iv)
to release, replace or modify the obligation of any indorser or guarantor, or
any party who has given any collateral for any of all of the Obligations, or any
other party in any way obligated to pay any or all of the Obligations, and to
enforce or refrain from enforcing, or compromise or modify, the terms of any
obligation of any such endorser, guarantor or party; (v) to dispose of any and
all collateral

<PAGE>

securing the Obligations in any manner as the Bank, in its sole discretion, may
deem appropriate, and to direct the order and the enforcement of any and all
indorsements and guaranties relating to the Obligations in the Bank's sole
discretion; and (vi) to determine the manner, amount and time of application of
payments and credits, if any, to be made on all or any part of the Obligations
including, without limitation, if this Guaranty is limited in amount, to make
any such application to Obligations, if any, in excess of the amount of this
Guaranty.

            (c) Notwithstanding any other provision in this Guaranty, Guarantor
irrevocably waives, without notice, any right he or she may have at law or in
equity (including without limitation any law subrogating Guarantor to the rights
of the Bank) to seek contribution, indemnification or any other form of
reimbursement from Borrower or any other obligor or guarantor of the Obligations
for any disbursement made under this Guaranty or otherwise.

      4. Termination. This Guaranty shall remain in full force and effect as to
each Guarantor until actual receipt by the Bank officer responsible for
Borrower's relationship with the Bank of written notice of Guarantor's intent to
terminate (or Guarantor's death or incapacity) plus the lapse of a reasonable
time for the Bank to act on such notice (the "Receipt of Notice"); provided,
however, this Guaranty shall remain in full force and effect thereafter until
all Obligations outstanding, or contracted or committed for (whether or not
outstanding), before such Receipt of Notice by the Bank, and any extensions,
renewals or replacements thereof (whether made before or after such Receipt of
Notice), together with interest accruing thereon after such Receipt of Notice,
shall be finally and irrevocably paid in full. Discontinuance of this Guaranty
as to one Guarantor shall not operate as a discontinuance hereof as to any other
guarantor. Payment of all of the Obligations from time to time shall not operate
as a discontinuance of this Guaranty, unless a Receipt of Notice as above
provided has been received by the Bank. Guarantor agrees that, to the extent
that Borrower makes a payment or payments to the Bank on the Obligations, or the
Bank receives any proceeds of collateral to be applied to the Obligations, which
payment or payments or any part thereof are subsequently invalidated, declared
to be fraudulent or preferential, set aside or otherwise are required to be
repaid to Borrower, its estate, trustee, receiver or any other party, including,
without limitation, under any bankruptcy law, state or federal law, common law
or equitable cause, then to the extent of such repayment, the obligation or part
thereof which has been paid, reduced or satisfied by such amount shall be
reinstated and continued in full force and effect as of the date such initial
payment, reduction or satisfaction occurred, notwithstanding any contrary action
which may have been taken by the Bank in reliance upon such payment or payments.
As of the date any payment or proceeds of collateral are returned, the statute
of limitations shall start anew with respect to any action or proceeding by the
Bank against Guarantor under this Guaranty.

      5. Expenses. Guarantor agrees to reimburse the Bank on demand for all the
Bank's expenses, damages and losses of any kind or nature, including without
limitation costs of collection and actual attorneys' fees and disbursements
whether for internal or external counsel incurred by the Bank in attempting to
enforce this Guaranty, collect any of the Obligations including any workout or
bankruptcy proceedings or other legal proceedings or appeal, realize on any
collateral, defense of any action under the prior paragraph or for any other
purpose related to the Obligations (collectively, "Expenses"). Expenses will
accrue interest at the highest default rate in any instrument evidencing the
Obligations until payment is actually received by the Bank. Guarantor shall
provide Bank with the same financial statements and other information Borrower
is required to provide to Bank under the Loan Agreement between Bank and
Borrower dated March 31, 1998, as it may be amended, extended or replaced.

      6. Financial and Other Information. Guarantor represents that its assets
are not subject to any liens, encumbrances or contingent liabilities except as
fully disclosed to the Bank in such statements. Guarantor authorizes the Bank
from time to time to obtain, verify and review all financial data deemed
appropriate by the Bank in connection with this Guaranty and the Obligations,
including without limitation credit reports from agencies. Guarantor understands
this Guaranty and has satisfied itself as to its meaning and consequences and
acknowledges that it has made its own arrangements for keeping informed of
changes or potential changes affecting the Borrower including the Borrower's
financial condition.

      7. Security; Right of Setoff. As further security for payment of the
Obligations, Expenses and any other obligations of Guarantor to the Bank,
Guarantor hereby grants to the Bank a security interest in all money, securities
and other property of Guarantor in the actual or constructive possession or
control of the Bank or its affiliates including without limitation all deposits
and other accounts owing at any time by the Bank or any of its affiliates in any
capacity to Guarantor in any capacity (collectively, "Property"). The Bank shall
have the right to set off Guarantor's Property against any of Guarantor's
obligations to the Bank. Such set-off shall be deemed to have been exercised
immediately at the time the Bank or such affiliate elect to do so. The Bank
shall also have all of the rights and remedies of a secured party under the
Uniform Commercial Code in effect in the State of New York as of the date of
this Guaranty in addition to those under this Guaranty and other applicable law
and agreements.

      8. No Transfer of Assets. Guarantor shall not transfer, reinvest or
otherwise dispose of its assets in a manner or to an extent that would or might
impair Guarantor's ability to perform its obligations under this Guaranty.

      9. Nonwaiver by the Bank; Miscellaneous. This Guaranty is intended by
Guarantor to be the final, complete and exclusive expression of the agreement
between Guarantor and the Bank. This Guaranty may be assigned by the Bank, shall
inure to the benefit of the Bank and its successors and assigns, and shall be
binding upon Guarantor and his or her legal representative, successors and
assigns and any participation may be granted by the Bank herein in connection
with the assignment or granting of a participation by the Bank in the
Obligations or any part thereof. All rights and remedies of the Bank are
cumulative, and no such right or remedy shall be exclusive of any other right or
remedy. This Guaranty does not supersede any other guaranty or security granted
to the Bank by Guarantor or others (except as to Guarantor's Waiver of
Subrogation rights above). No single, partial or delayed exercise by the Bank of
any right or remedy shall preclude exercise by the Bank at any time at its sole
option of the same or any other right or remedy of the Bank without notice.
Guarantor expressly disclaims any reliance on any course of dealing or usage of
trade or oral representation of the Bank including, without limitation,
representations to make loans to Borrower or enter into any other agreement with
Borrower or Guarantor. No course of dealing or other conduct, no oral agreement
or representation made by the Bank or usage of trade shall operate as a waiver
of any right or remedy of the Bank. No waiver or amendment of any right or
remedy of the Bank or release by the Bank shall be effective unless made
specifically in writing by the Bank. Each provision of this Guaranty shall be
interpreted as consistent with existing law and shall be deemed amended to the
extent necessary to comply with any conflicting law. If any provision
nevertheless is held invalid, the other provisions shall remain in effect.
Guarantor agrees that in any legal proceeding, a copy of this Guaranty kept in
the Bank's course of business may be admitted into evidence as an original.
Captions are solely for convenience and not part of the substance of this
Guaranty. If this Guaranty is limited pursuant to Paragraph 2 hereof, until the
Obligations are indefeasibly paid in full, the Guaranteed Amount shall not be
reduced in any manner whatsoever by any amounts which the Bank may realize
before or after maturity of the Obligations (by acceleration, demand or
otherwise), as a result of payments made by or on behalf of Borrower or by or on
behalf of any other person or entity other than Guarantor primarily or
secondarily liable for the Obligations or any part thereof, or otherwise
credited to Borrower

<PAGE>

or such person or entity, or as a result of the exercise of the Bank's rights
with respect to any collateral for the Obligations or any part thereof. Payments
made to the Bank by Guarantor (other than, directly or indirectly, from
collateral or other persons or entities liable for any portion of the
Obligations) after maturity of the Obligations, by acceleration or otherwise,
shall reduce the Guaranteed Amount.

      10. Joint and Several. If there is more than one Guarantor, each Guarantor
jointly and severally guarantees the payment and performance in full of all
obligations under this Guaranty and the term "Guarantor" means each as well as
all of them. Guarantor also agrees that the Bank need not seek payment from any
source other than the undersigned Guarantor. This Guaranty is a primary
obligation. Guarantor's obligations hereunder are separate and independent of
Borrower's, and a separate action may be brought against Guarantor whether or
not action is brought or joined against or with Borrower or any other party.

      11. Authorization. Guarantor certifies that it is an entity in the form
described above duly organized and in good standing under the laws of the State
of its organization and duly authorized to do business in each State material to
the conduct of its business. Guarantor has determined that the execution of this
Guaranty will be in its best interests, to its direct benefit, incidental to its
powers, and in furtherance of its duly acknowledged purposes and objectives.
Execution of this Guaranty by the persons signing below has been authorized by
all necessary corporate action, including directors' and shareholder consent or
(as appropriate) is authorized by its partnership agreement or governing
instrument. Guarantor's chief executive office is located at the above address.

      12. Notices. Any demand or notice hereunder or under any applicable law
pertaining hereto shall be in writing and duly given if delivered to Guarantor
(at its address on the Bank's records) or to the Bank (at the address on page
one and separately to the Bank officer responsible for Borrower's relationship
with the Bank). Such notice or demand shall be deemed sufficiently given for all
purposes when delivered (i) by personal delivery and shall be deemed effective
when delivered, or (ii) by mail or courier and shall be deemed effective three
(3) business days after deposit in an official depository maintained by the
United States Post Office for the collection of mail or one (1) business day
after delivery to a nationally recognized overnight courier service (e.g.,
Federal Express). Notice by e-mail is not valid notice under this or any other
agreement between Guarantor and the Bank.

      13. Governing Law and Jurisdiction. This Guaranty has been delivered to
and accepted by the Bank and will be deemed to be made in the State of New York.
Unless provided otherwise under federal law, this Guaranty will be interpreted
in accordance with the laws of the State of New York excluding its conflict of
laws rules. GUARANTOR HEREBY IRREVOCABLY CONSENTS TO THE EXCLUSIVE JURISDICTION
OF ANY STATE OR FEDERAL COURT IN ANY JUDICIAL DISTRICT OR COUNTY IN THE STATE OF
NEW YORK WHERE THE BANK MAINTAINS A BRANCH AND CONSENTS THAT THE BANK MAY EFFECT
ANY SERVICE OF PROCESS IN THE MANNER AND AT GUARANTOR'S ADDRESS SET FORTH ABOVE
FOR PROVIDING NOTICE OR DEMAND; PROVIDED THAT NOTHING CONTAINED IN THIS GUARANTY
WILL PREVENT THE BANK FROM BRINGING ANY ACTION, ENFORCING ANY AWARD OR JUDGMENT
OR EXERCISING ANY RIGHTS AGAINST GUARANTOR INDIVIDUALLY, AGAINST ANY SECURITY OR
AGAINST ANY PROPERTY OF GUARANTOR WITHIN ANY OTHER COUNTY, STATE OR OTHER
FOREIGN OR DOMESTIC JURISDICTION. Guarantor acknowledges and agrees that the
venue provided above is the most convenient forum for both the Bank and
Guarantor. Guarantor hereby waives (i) any objection to venue and any objection
based on a more convenient forum in any action instituted under this Guaranty;
(ii) any right to assert any counterclaim or setoff or any defense based upon a
statute of limitations, a claim of laches or of any other legal theory; and

                          MASTER EQUIPMENT LEASE NO. 1
                                  (True Lease)

This Master Equipment Lease dated as of April 7, 1998, together with all
Equipment Schedules annexed hereto, is between M&T Financial Corporation, a New
York corporation with its principal office at One Fountain Plaza, Buffalo, NY
14203, Attention: Counsel's Office ("Lessor"), and CVC Products, Inc. a
corporation organized under the laws of the state of Delaware with its chief
executive office at 525 Lee Road, Rochester, NY 14606 ("Lessee").

Lease. Subject to the terms hereof, Lessor shall lease to Lessee, and Lessee
shall lease from Lessor, the units of personal property (collectively, the
"Equipment" and separately, a "Unit") described on each Equipment Schedule (each
an "Equipment Schedule" or "Schedule") now or hereafter attached hereto, each of
which shall incorporate all the terms and conditions of this Master Equipment
Lease. Each Equipment Schedule shall constitute a separate lease and the term
"Lease" as used below shall refer to an individual Equipment Schedule which
incorporates this Master Equipment Lease, together with the Certificate of
Acceptance for that Schedule. In case of inconsistency, the terms of the
Schedule shall control.

Term. The "Term" of this Lease shall consist of (i) the Interim Term (if any)
and (ii) the Base Term. The Interim Term will commence on the date the Lessor
disburses funds to pay for the Equipment and shall extend to but not include the
Rent Commencement Date (the "Interim Term"). The Initial Base Term shall
commence on the earlier of (a) the Rent Commencement Date stated on the
Equipment Schedule or (b) the date of the Lessee's Certificate of Acceptance for
the Equipment (the "Acceptance Date") and shall continue for the number of
periods specified on the Schedule (the "Base Term"). Lessor is authorized to
enter the commencement date and other ministerial information on the Schedule
upon receipt of the Certificate of Acceptance. The terms and conditions of this
Lease shall continue in effect during any renewal term.

Rent; Late Charge. Lessee agrees to pay directly to Lessor at the above address
or to Lessor's Assignee the rental payments plus any interim rent as specified
on the Equipment Schedule together with all other amounts which may become due
under this Lease (the "Rent"). All Rent shall be paid without notice or demand.
If any Rent is not received within 5 days of the date due, Lessor may charge and
Lessee shall be obligated to pay a late charge in the amount specified on the
Equipment Schedule, or, if none is so specified, 5% of the delinquent amount.

Net Lease; Lessee's Obligations Absolute. This Lease is a net lease. Lessee's
obligation to pay Rent shall be absolute and unconditional and shall not be
subject to any abatement, deferral, reduction, defense, counterclaim, setoff or
recoupment for any reason, including without limitation any claim against the
manufacturer or loss of possession or use of the Equipment.

Disclaimer of Warranties; Lessee's Obligations. LESSEE ACKNOWLEDGES THAT FOR THE
PURPOSES OF UCC ARTICLE 2A THIS IS A STATUTORY FINANCE LEASE AND LESSOR IS NOT
AN AGENT OF THE MANUFACTURER OR VENDOR OF THE EQUIPMENT. LESSEE SELECTED THE
EQUIPMENT AND VENDOR. LESSEE IS SATISFIED THAT THE EQUIPMENT IS SUITABLE AND FIT
FOR LESSEE'S PURPOSES. LESSOR MAKES NO WARRANTY EITHER EXPRESS OR IMPLIED, AS
TO, WITHOUT LIMITATION, QUALITY, CONDITION, MERCHANTABILITY, DESIGN, CAPACITY,
WORKMANSHIP OR PERFORMANCE OF THE EQUIPMENT, OR ITS FITNESS FOR ANY PARTICULAR
PURPOSE. No defect or unsuitability of the Equipment or delay in delivery shall
relieve Lessee of the obligation to pay Rent or any other obligation under this
Lease. Lessor hereby assigns to Lessee any interest it may have in
manufacturers' warranties which Lessee may enforce in Lessee's name and at
Lessee's sole


                                       1
<PAGE>

expense. Lessee knows it may have rights under any vendor purchase documents and
can contact the vendor if any for a description of such rights.

Assignment. LESSEE MAY NOT ASSIGN, SUBLEASE, TRANSFER OR DISPOSE OF ANY OF ITS
RIGHTS UNDER THIS LEASE without Lessor's prior written consent. LESSEE SHALL
REMAIN PRIMARILY LIABLE ON THE LEASE. Lessor may assign this Lease without
Lessee's consent and Lessee admits that such assignment constitutes no material
increase in Lessee's duties or risk and Lessee would not object even if it did.
Lessee's obligations under the Lease shall constitute a direct, independent and
unconditional obligation of Lessee to any Assignee of Lessor. Lessee agrees that
Lessor's Assignee shall have the right to exercise all rights, privileges and
remedies (either in its own name or in the name of Lessor) which by the terms of
this Lease are permitted to be exercised by Lessor.

Title; True Lease. Lessor has and will retain good and marketable title to and a
residual interest in the Equipment and not merely a security interest in it.
Lessor and Lessee do not intend this agreement as a disguised installment sale
or disguised security agreement. Title to any replacement parts or integral
additions to the Equipment shall automatically vest in Lessor.

Risk of Loss. Lessee assumes the entire risk of loss to the Equipment. Lessee
shall advise Lessor in writing promptly of the circumstances and extent of any
damage. If the Equipment is irreparably damaged, lost, stolen or taken by
eminent domain or otherwise, Lessee shall, at Lessor's option, (a) replace it
with like equipment approved by Lessor and transfer title to such replacement
item to Lessor, or (b) pay to Lessor all Rent due and to become due, less the
net amount of any recovery actually received by Lessor from insurance or
otherwise. When, in Lessor's sole discretion, the Equipment can be repaired,
Lessee shall at its expense promptly effect such repairs as Lessor deems
necessary for compliance with this Lease. Any insurance proceeds received by
Lessor for repair of the Equipment shall, at Lessor's option, be paid either
directly to the party completing the repairs, or to reimburse Lessee for the
cost of such repairs; provided, however, that Lessor shall have no obligation to
make any payment until receipt of evidence satisfactory to Lessor that such
repairs have been completed; and further provided that Lessor may apply such
proceeds to the payment of Rent if there shall have occurred and be continuing
an Event of Default or any event which with lapse of time or notice, or both,
would become an Event of Default. Lessee shall, upon Lessor's request,
undertake, by litigation or otherwise, in Lessee's name, the collection of any
claim against any person for such loss or taking, but Lessor shall not be
obligated to undertake the collection of any such claim.

Representations and Warranties of Lessee. Lessee represents and warrants that:
it is duly organized and in good standing under the laws of the State in which
it was formed and duly authorized to do business in each jurisdiction where
failure to be so authorized might have a material adverse effect on its
financial condition or assets; it has the legal right and power and has taken
all necessary corporate or partnership action to authorize execution, delivery
and performance of its obligations under this Lease; this Lease constitutes a
valid obligation of Lessee enforceable in accordance with its terms; and
execution, delivery and performance of this Lease will not violate the terms or
constitute a breach of any other agreement to which Lessee is a party or by
which it is bound.

Maintenance and Repairs; Business Purpose Only. Lessee at its sole expense shall
cause the Equipment to be maintained and kept in good repair according to the
manufacturer's specifications. Lessee shall use the Equipment only in the manner
and for the BUSINESS PURPOSES for which it was designed and intended.

Insurance. Lessee shall maintain at all times property damage, fire, theft and
comprehensive insurance for the full replacement value of the Equipment with
loss payable provisions in favor of Lessor as its interests may appear and
maintain public liability insurance in the amounts required by Lessor for the
relevant Equipment Schedule, naming Lessor as additional insured, all under
policies in form, substance and amount and written by companies approved


                                       2
<PAGE>

by Lessor.

Compliance; Inspection. Lessee shall comply with all governmental laws,
regulations, requirements and rules, including without limitation environmental
and licensing laws and all manufacturer's operating instructions and warranty
requirements for the Equipment, and with the conditions and requirements of all
policies of insurance with respect to the Equipment and this Lease. At any time
during business hours, Lessor may enter the premises where the Equipment is
located, to inspect the Equipment.

Taxes and Costs. Lessee shall pay all applicable sales and other taxes, license
and registration fees, assessments and other government charges, however
designated, based upon the Equipment or the Rent or upon the operation,
maintenance, repair, return or other disposition of the Equipment, or for
titling or registering the Equipment, including taxes measured by the net income
of Lessor to the extent that such taxes are assessed in lieu of other
governmental charges. If Lessee represents that Lessee is exempt from payment of
income taxes and sales taxes, Lessee will provide Lessor with evidence of such
exemptions. Lessee shall pay all shipping and delivery charges and other
expenses incurred in connection with the Equipment and pay all lawful claims
which might become a lien on the Equipment.

General Indemnity. Lessee shall indemnify and hold Lessor harmless from and
against all claims, losses, liabilities, damages, judgments, suits, and all
legal proceedings, and any and all costs and expenses (including without
limitation attorneys' fees and disbursements whether for internal or outside
counsel), arising in connection with the manufacture, purchase, ownership,
delivery, installation, possession, use, storage, operation, failure,
maintenance, repair, return, repossession or other disposition of the Equipment
or with this Lease including without limitation claims for injury to or death of
persons and for damage to property (collectively "Claims"). Lessee shall give
Lessor and any Assignee prompt notice of any Claim.

Tax Indemnity. Lessee represents, warrants and covenants that the entire
Equipment cost to Lessor qualifies as cost of "property" for purposes of
Internal Revenue Code ss.168, as amended; no person other than Lessor has
claimed or will claim any tax deduction or credit related to the Equipment;
Lessee will take all actions requested at any time to protect Lessor's tax
ownership of the Equipment; the Equipment is not "limited use property" for
purposes of Revenue Procedures 75-28 (1975-1 C.B. 752) and 76-30 (1976 C.B.
847); and the Equipment will be placed in service within the meaning of I.R.C.
ss.168 by no later than the date specified in the Tax Rider. Lessee agrees not
to do anything to impair or lessen the value of Lessor's anticipated tax
benefits related to the Equipment (as set forth on a Tax Rider to this Lease)
and expressly agrees that Claims under the indemnity provided in the preceding
paragraph shall include any disallowance, elimination, recapture, reduction or
disqualification, in whole or in part, of any tax benefits of Lessor incurred as
a result of any act or omission or misrepresentation of Lessee (a "Loss"). If
Lessor suffers a Loss, Lessee shall pay to Lessor as additional Rent on the next
succeeding rental payment date after Lessor delivers to Lessee written notice of
a Loss, or if there is no such date, within 30 days after such notice, the
amount which, after deduction of all taxes, interest, additions to tax and
penalties that have been or will be required to be paid by Lessor at the highest
marginal corporate income or franchise tax rates under all applicable federal,
state and local laws, regulations and ordinances, will preserve the Net Economic
Return that would have been realized by Lessor had such Loss not occurred. In
the case of a Loss resulting from Lessor's inability to offset, for federal or
local income or State franchise tax purposes, income taxable at a rate equal to
Lessor's highest marginal corporate tax rate, basic Rent, and the Table of
Stipulated Loss and Early Termination Values for the related Schedule shall be
adjusted to preserve the Net Economic Return. "Net Economic Return" means the
maintenance, at a minimum, of Lessor's (i) after-tax yield (ii) after-tax
aggregate cash flows, and (iii) return on assets as computed by Lessor as of the
date of the execution of the Schedule. All of Lessor's rights and privileges
arising from the indemnity in this paragraph shall survive the expiration or
other termination of this Lease. For purposes of this indemnity the term
"Lessor" shall include any affiliated group (within the meaning of I.R.C.


                                       3
<PAGE>

ss.1504) of which Lessor is a member for any year in which a consolidated income
tax return is filed for such affiliated group.

Location. Lessee shall not remove the Equipment from its business location
specified on the respective Equipment Schedule without Lessor's prior written
consent. Upon the expiration or termination of this Lease, unless Lessee
purchases the Equipment Lessee shall, at its sole expense, store and continue to
insure the Equipment for up to 180 days and shall deliver the Equipment to
Lessor in good condition, ordinary wear and tear excepted, at a location within
the United States designated by the Lessor.

Financial Statements. Lessee shall maintain a system of accounts established and
administered in accordance with generally accepted accounting principles and
practices for its industry consistently applied, and, within thirty (30) days
after the end of each fiscal quarter, deliver to Lessor a balance sheet as of
the end of such quarter and statement of operations and cash flows for such
quarter, and within one hundred twenty (120) days after the end of each fiscal
year, deliver to Lessor a balance sheet as of the end of such year and year end
statement of operations and cash flows for such year in each case prepared in
accordance with generally accepted accounting principles for its industry
consistently applied and certified by Lessee's chief financial officer, or, in
the case of year end financial statements, audited by an independent public
accountant firm acceptable to Lessor, to be correct and complete in accord with
Lessee's records and to present fairly the results of Lessee's operations and
cash flows and its financial position at year end.

No Liens. Lessee shall not create or suffer to exist any lien or other
encumbrance of any kind upon the Equipment or this Lease and agrees that if
Lessee breaches this covenant Lessor may cancel this Lease.

Quiet Enjoyment; Equipment is Personality. Lessor covenants that so long as no
Event of Default shall have occurred, Lessee shall be entitled to quiet
possession and use of the Equipment in accordance with this Lease. Lessor and
Lessee agree that the Equipment shall remain personal property. Lessee will
obtain and deliver upon Lessor's request any landlord and mortgagee waivers in
recordable form, satisfactory to Lessor, from all persons claiming any interest
in the real property on or in which the Equipment is located.

Events of Default. An event of default ("Event of Default") will have occurred
if (a) Lessee fails to pay any Rent within 10 days of the date due whether by
acceleration or otherwise; (b) Lessee or any guarantor of this Lease (a
"Guarantor") fails to perform when due any obligation under this Lease or any
other agreement with the Lessor; (c) any of Lessee's debts is accelerated or an
event occurs which after notice or lapse of time would permit such acceleration;
(d) Lessee or a Guarantor is dissolved, suspends its present business, agrees to
a merger or other absorption or to transfer or otherwise dispose of
substantially all of its assets, makes or sends notice of a bulk sale, becomes
insolvent (however such insolvency is evidenced), generally fails to pay its
debts as they become due, fails to pay, withhold or collect any tax as required
by law, has served or filed against it or its assets any lien not permitted
above or has entered against it or its Guarantor or assets any judgment, order
or award; (e) a receiver or similar trustee is appointed for Lessee or its
Guarantor or assets (with or without its consent), or Lessee or Guarantor makes
an assignment for the benefit of creditors or commences or has commenced against
it a proceeding pursuant to any bankruptcy law, and such appointment or
proceeding is not dismissed within 60 days; or (f) any representation or
warranty made in this Lease or related documents or other statements provided by
Lessee or Guarantor proves to have been incorrect or misleading in any material
respect when made.

Remedies. Immediately upon the occurrence of any Event of Default, Lessor may,
without notice or demand, take any or all of the following steps: (a)
immediately terminate the Lease and require Lessee, at its expense, promptly to
return all or any portion of the Equipment to the possession of Lessor at such
place as Lessor may designate; (b) without process of law, enter upon the
premises where the Equipment is located and take immediate possession of


                                        4
<PAGE>

the Equipment, free from all claims for loss or damage caused by repossession;
(c) declare immediately due and payable an amount equal to the present value of
(1) all unpaid Rent due and to become due during the entire Term, plus (2) the
purchase price payable under Lessee's purchase option, if constructively
exercised, using a factor selected by Lessor in its sole discretion to determine
present value; (d) sell, release or otherwise dispose of the Equipment as is or
with any commercially reasonable preparation, at public or private sale, in one
or more parcels, upon any terms, at such place(s) and time(s) and to such
persons or firms as Lessor deems best, without demand or notice, although Lessee
agrees ten (10) business days' written notice if given shall be deemed
reasonable notice; or (e) exercise any other right or remedy in equity or under
applicable law, including without limitation remedies of a secured party under
the Uniform Commercial Code. Lessee shall be liable for all costs and expenses
incurred by Lessor for sale or re-lease, including reasonable brokers'
commissions and attorneys' fees and disbursements, whether for internal or
outside counsel. To the extent permitted by applicable law, Lessee hereby waives
any valuation, inquisition, stay, appraisal or redemption laws which, but for
this provision, might be applicable to any sale or re-lease of the Equipment.

Lessor's Right to Cure. Lessor may at its option perform any of Lessee's
obligations omitted by Lessee, at Lessee's expense payable upon demand.

Purchase Option. Lessee shall have only such option to purchase the Equipment
upon expiration of the Lease (if any) as specified in a separate Purchase Option
Rider to the Schedule. Any option shall be suspended during the existence of any
Event of Default. If no price is specified, the price shall be the fair market
value of the Equipment as determined by the Lessor at the end of the Term.

Further Assurances. Lessee will execute all documents and take all further
actions requested by Lessor to protect Lessor's interests under this Lease,
including without limitation Uniform Commercial Code financing statements.
Lessor is authorized to file this Lease as a security agreement in lieu of a
financing statement, to file financing statements without the signature of
Lessee and to execute finaning statements on behalf of Lessee. Lessee will pay
all costs of filing financing statements with respect to this Lease, including
without limitation documentary stamp taxes. Lessee will cause Lessor's interest
in the Equipment to be noted on any certificate of title relating to the
Equipment.

Power of Attorney. Lessee irrevocably and unconditionally appoints Lessor
Lessee's Attorney-in-Fact to, at any time, in Lessee's name or otherwise (a)
execute financing statements relating to the Equipment, (b) execute applications
for certificates of title or notices of lien relating to titled Equipment, (c)
endorse checks, drafts or other instruments drawn by the issuer of insurance
covering the Equipment or (d) execute and deliver any writing and take any other
actions that the Lessor deems necessary or desirable to perfect or protect
Lessor's interests under this Lease. This power is coupled with an interest and
if Lessee is a natural person shall not be affected by any subsequent disability
of the Lessee.

Enforceability. This Lease shall be binding upon Lessee's successors and assigns
and shall be enforceable by Lessor's successors and assigns.

Non-Waiver; Etc. No course of dealing nor any delay or omission in Lessor's
exercise of any right shall operate as a waiver of any of Lessor's rights. A
waiver on any one occasion shall not bar or waive any right or remedy of Lessor
on any future occasion. No waiver or consent shall be binding upon Lessor unless
it is in writing and signed by Lessor.

No Commitment; Lessor's Right to Terminate Commitments. This Master Equipment
Lease is not a legal commitment to lend and Lessor shall have no obligation to
enter into any Schedule unless (1) Lessor has issued a


                                       5
<PAGE>

specific commitment for such Schedule, (2) no Event of Default exists with
respect to any agreement or other obligation of Lessee in any capacity to Lessor
or any of its affiliates in any capacity, and (3) none of the following has
occurred: (a) there has been a material adverse change in Lessee's financial
position or credit standing as determined by Lessor in its sole discretion; (b)
the Equipment fails to be delivered and accepted by Lessee before the commitment
expires; (c) Lessee or any Guarantor fails to cause its counsel to deliver on
its behalf any legal opinion requested by the Lessor; (d) Lessee fails to
deliver evidence satisfactory to Lessor that Lessee has obtained and will
maintain in force during the Lease Term all federal, state and local permits,
licenses and approvals necessary for the acquisition, transportation, operation
and maintenance of the Equipment, including without limitation disposal of all
associated wastes and by-products and protection of operators and other persons
in the vicinity of the Equipment; or (e) any other condition specified in the
Schedule has not been fulfilled. Immediately upon Lessor's termination or
rejection of a Schedule or commitment based on this section, Lessee will return,
and reimburse Lessor for all sums disbursed by Lessor with respect to, the
Equipment and proposed Schedule, including without limitation all Lessor's
attorneys' fees and disbursements, whereupon, if Lessee is not in default with
respect to any agreement with Lessor, Lessor will transfer to Lessee without
warranty or recourse any rights Lessor may have with respect to the Equipment.

Miscellaneous. This Lease constitutes the entire agreement between Lessor and
Lessee relating to the Equipment and supersedes all prior dealings. This Lease
may be amended only in a writing signed by both parties. THIS LEASE SHALL BE
GOVERNED BY THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO ITS PRINCIPLES OF
CONFLICTS OF LAW, AND SHALL BE DEEMED EXECUTED AND PERFORMED IN NEW YORK; and
shall be deemed amended to the extent necessary to comply with any inconsistent
law. If any provision is nevertheless determined to be invalid, the remaining
provisions shall remain in effect. The captions in this Lease are for
convenience only.

Lessee's Waivers. Lessor and Lessee each waive any right to trial by jury in
connection with this Lease. In any action or other legal proceeding relating to
this Lease, Lessee (a) consents to the personal jurisdiction of any state or
federal court located in the State of New York, (b) waives objection to the
laying of venue, (c) waives personal service of process and subpoenas, (d)
consents to the service of process and subpoenas by registered mail directed to
the Lessee's last known address, with such service deemed complete five days
after mailing, (e) waives any right to assert any counterclaim or setoff or any
defense based upon any statute of limitations or any claim of laches, (f) waives
its right to attack any final judgment that is obtained as a direct or indirect
result of any such action and (g) consents to each such final judgment being
sued upon in any court having jurisdiction. LESSEE WAIVES ANY AND ALL RIGHTS AND
REMEDIES CONFERRED BY UCC ARTICLE 2A SECTIONS 508-522, INCLUDING WITHOUT
LIMITATION ANY RIGHTS TO (a) CANCEL OR REPUDIATE THE LEASE, (b) REJECT OR REVOKE
ACCEPTANCE OF THE EQUIPMENT, (c) RECOVER DAMAGES FROM THE LESSOR FOR BREACH OF
WARRANTY OR FOR ANY OTHER REASON, (d) CLAIM A SECURITY INTEREST IN ANY REJECTED
EQUIPMENT IN LESSEE'S POSSESSION OR CONTROL, (e) DEDUCT FROM RENT ALL OR ANY
PART OF ANY CLAIMED DAMAGES RESULTING FROM THE LESSOR'S DEFAULT UNDER THE LEASE,
(f) ACCEPT PARTIAL DELIVERY OF THE EQUIPMENT, (g) RECOVER FROM LESSOR OR
ASSIGNEE ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES FOR ANY
REASON WHATSOEVER, AND (h) SPECIFIC PERFORMANCE, REPLEVIN OR THE LIKE FOR ANY OF
THE EQUIPMENT. Lessee also waives any statutory right it may have now or in the
future to require the Lessor to sell or re-lease the Equipment or otherwise to
mitigate damages.

Early Termination; Interest on Accelerated Payment. Early Termination of any
Schedule by Lessee is permitted only upon payment in full of all amounts due
pursuant to the early termination and stipulated loss value table attached as a
rider to the Equipment Schedule. Interest shall accrue on payments due under
this paragraph from the date of


                                        6
<PAGE>

termination until payment is actually received by Lessor at the rate of two
percent (2%) per month; provided, however, that Lessor and Lessee do not intend
for Lessee to pay interest in excess of the maximum rate permitted by law. No
partial prepayments are permitted.

Notices. Notices shall be deemed delivered upon deposit in the United States
mail postage prepaid directed to Lessor and Lessee at the addresses set forth
above or in any subsequent written notice to the other party. Lessee shall
immediately notify Lessor and any Assignee of any change in the location of the
Equipment or in Lessee's address, name, management, financial condition or form
of organization.

Application of Payments. Payment shall be applied first to Lessor's costs and
Expenses including without limitation attorney's fees, collection costs and
expenses incurred in performing Lessee's obligations under this Lease, next to
charges and fees such as late charges, and last to other Rent.

LESSEE ACKNOWLEDGES THAT ONLY LESSOR'S ORIGINAL OF EACH EQUIPMENT SCHEDULE

                            FUNDS TRANSFER AGREEMENT
                              SINGLE PAYMENT ORDER

To induce Lessor to execute the funds transfer payment order on the front of
this form, Lessee makes the following waivers and agrees to the following terms
and conditions.

      1.    Waiver of Lessor's Security Procedures. Lessee hereby rejects and
            waives the protection of the Lessor's customary funds transfer
            security procedures, and agrees that a request for personal
            identification in a procedure including signature comparison shall
            be deemed a commercially reasonable security procedure for purposes
            of Article 4A of the Uniform Commercial Code.

      2.    Authorization. Lessee shall supply Lessor with all information that
            Lessor requests including, but not limited to, money amounts;
            beneficiary's account number, name and Lessor; value date;
            supplemental instructions; and further evidence of the authority of
            any of Lessee's authorized representatives to issue Payment Orders
            or to do any other act contemplated under this Agreement. For
            Lessee's protection, Lessor may reject any Payment Order if Lessor
            is unable to obtain satisfactory verification of the Order or its
            due authorization. If Lessee is an entity, the person signing this
            agreement certifies that he or she is duly authorized to execute
            such transaction on behalf of Lessee; and acknowledges that any
            false statement will render him or her personally liable for
            monetary damages as well as criminal penalties including substantial
            fines and imprisonment under federal and state law.

      3.    Account Number Controls. Lessee ACKNOWLEDGES RECEIPT OF NOTICE THAT
            M&T Lessor, ALL INTERMEDIARY LessorS AND BENEFICIARY'S Lessor ARE
            ENTITLED TO RELY ON THE BENEFICIARY'S ACCOUNT NUMBER AND ANY Lessor
            IDENTIFYING NUMBER AS STATED IN THE PAYMENT ORDER AS RECEIVED EVEN
            IF THE NUMBER AND NAME GIVEN FOR THE BENEFICIARY REFER TO DIFFERENT
            PERSONS OR LessorS. Lessee IS WARNED TO VERIFY ALL ACCOUNT NUMBERS
            AND Lessor NUMBERS WITH EXTRAORDINARY CARE.

      4.    Risk of Clear Text. Lessee understands that all Payment Orders are
            transmitted in Clear Text and Lessee assumes full responsibility for
            all such Payment Orders executed by Lessor at Lessee's request.

      5.    Standard of Care. Lessee agrees Lessor has no responsibility beyond
            executing the transaction requested with ordinary care, subject to
            this Agreement. Lessor shall be conclusively deemed to have
            exercised ordinary care if Lessor has followed procedures customary
            in the industry or if Lessee has not followed such procedures.

      6.    Cancellation. Lessee shall have no right to amend a Payment Order or
            to cancel it after Lessor has begun processing it. In case of Lessee
            error, Lessor has no obligation but reserves the right to attempt to
            assist Lessee to recover its funds.

      7.    Limited to Available Funds. A Payment Order is debited to Lessee's
            designated account when it is executed by Lessor. Lessee agrees that
            its Payment Orders shall not exceed the available balance in
            Lessee's account on the execution date. If Lessee's account does not
            contain sufficient available funds on that date, Lessor may reject
            any or all of Lessee's Payment Orders for that date, charge any of
            Lessee's other accounts with Lessor, or execute any one or more
            Payment Orders on that date; and Lessor shall not be liable for any
            damages (including without limitation special or consequential
            damages) Lessee suffers as a result of such rejections. If Lessor
            does in its discretion execute a Payment Order which results in an
            overdraft in Lessee's account, Lessor shall be entitled to charge
            and Lessee shall be obligated to pay interest on such overdraft.
            Lessee's account will be liable for statutory overdraft charges
            whether or not the overdraft Payment Order is executed.

      8.    Expenses. Lessee agrees to pay Lessor's customary funds transfer
            fees as in effect from time to time and to reimburse Lessor for any
            out-of-pocket expenses incurred by Lessor. Such fees and expenses
            shall be paid in cash immediately on demand or by Lessor's debiting
            Lessee's account(s) at Lessor.

      9.    Notice of Errors. Lessee shall promptly review the transfer
            confirmation or advice mailed to Lessee by Lessor after each
            transfer and notify Lessor of any discrepancy in writing as soon as
            possible and in any event within 60 calendar days of the transfer.
            Lessee shall also promptly review and reconcile its periodic
            statements of account provided by Lessor and report any
            discrepancies to Lessor in writing within 60 calendar days after the
            statement date. Lessee expressly agrees that its failure to so
            report any such discrepancies shall relieve Lessor of any liability
            for interest on any refund to which Lessee may be entitled with
            respect to such unreported discrepancies. Statements and advices
            shall be deemed received 5 days after mailing.

      10.   Disclosure of Information. Lessee acknowledges that Lessor may be or
            become required by federal regulation to report or make information
            available concerning all or some classes of funds transfers.

      11.   Force Majeure. Lessee agrees that Lessor is not liable for any
            error, interruption, delay, or failure in transmission occasioned by
            any circumstances beyond Lessor's control including but not limited
            to discrepancies or ambiguity in any Payment Order, funds transfer
            system unavailability, weather, failure of power, other utilities or
            communication media, strikes, industrial sabotage, war, governmental
            interference, and error, delay, insolvency or unavailability of
            other receiving, intermediary or beneficiary Lessors.

      12.   Indemnity. Lessee agrees to hold Lessor harmless and indemnify
            Lessor for any and all claims, liabilities, demands, costs, expenses
            (including but not limited to attorneys' fees and disbursements),
            losses or damages of any nature whatsoever arising directly or
            indirectly from any Payment Order executed pursuant to this
            Agreement except for liability to Lessee caused by gross negligence
            or willful misconduct of Lessor. In no event shall Lessor be liable
            for any consequential or special damages.

      13.   Governing Law. This Agreement shall be governed by the internal laws
            of New York State (including without limitation Article 4A of the
            Uniform Commercial Code) and by applicable federal law and
            regulations.

All notices to Lessor shall be directed to the Manager, Commercial Loan
Operations, 3rd Floor, Manufacturers and Traders Trust Company, One Fountain
Plaza, Buffalo, New York 14203; all notices to Lessee shall be directed to
Lessee at the most recent address listed in the records of Lessor.

                            FUNDS TRANSFER AGREEMENT
                              SINGLE PAYMENT ORDER

To induce Lessor to execute the funds transfer payment order on the front of
this form, Lessee makes the following waivers and agrees to the following terms
and conditions.

      1.    Waiver of Lessor's Security Procedures. Lessee hereby rejects and
            waives the protection of the Lessor's customary funds transfer
            security procedures, and agrees that a request for personal
            identification in a procedure including signature comparison shall
            be deemed a commercially reasonable security procedure for purposes
            of Article 4A of the Uniform Commercial Code.

      2.    Authorization. Lessee shall supply Lessor with all information that
            Lessor requests including, but not limited to, money amounts;
            beneficiary's account number, name and Lessor; value date;
            supplemental instructions; and further evidence of the authority of
            any of Lessee's authorized representatives to issue Payment Orders
            or to do any other act contemplated under this Agreement. For
            Lessee's protection, Lessor may reject any Payment Order if Lessor
            is unable to obtain satisfactory verification of the Order or its
            due authorization. If Lessee is an entity, the person signing this
            agreement certifies that he or she is duly authorized to execute
            such transaction on behalf of Lessee; and acknowledges that any
            false statement will render him or her personally liable for
            monetary damages as well as criminal penalties including substantial
            fines and imprisonment under federal and state law.

      3.    Account Number Controls. Lessee ACKNOWLEDGES RECEIPT OF NOTICE THAT
            M&T Lessor, ALL INTERMEDIARY LessorS AND BENEFICIARY'S Lessor ARE
            ENTITLED TO RELY ON THE BENEFICIARY'S ACCOUNT NUMBER AND ANY Lessor
            IDENTIFYING NUMBER AS STATED IN THE PAYMENT ORDER AS RECEIVED EVEN
            IF THE NUMBER AND NAME GIVEN FOR THE BENEFICIARY REFER TO DIFFERENT
            PERSONS OR LessorS. Lessee IS WARNED TO VERIFY ALL ACCOUNT NUMBERS
            AND Lessor NUMBERS WITH EXTRAORDINARY CARE.

      4.    Risk of Clear Text. Lessee understands that all Payment Orders are
            transmitted in Clear Text and Lessee assumes full responsibility for
            all such Payment Orders executed by Lessor at Lessee's request.

      5.    Standard of Care. Lessee agrees Lessor has no responsibility beyond
            executing the transaction requested with ordinary care, subject to
            this Agreement. Lessor shall be conclusively deemed to have
            exercised ordinary care if Lessor has followed procedures customary
            in the industry or if Lessee has not followed such procedures.

      6.    Cancellation. Lessee shall have no right to amend a Payment Order or
            to cancel it after Lessor has begun processing it. In case of Lessee
            error, Lessor has no obligation but reserves the right to attempt to
            assist Lessee to recover its funds.

      7.    Limited to Available Funds. A Payment Order is debited to Lessee's
            designated account when it is executed by Lessor. Lessee agrees that
            its Payment Orders shall not exceed the available balance in
            Lessee's account on the execution date. If Lessee's account does not
            contain sufficient available funds on that date, Lessor may reject
            any or all of Lessee's Payment Orders for that date, charge any of
            Lessee's other accounts with Lessor, or execute any one or more
            Payment Orders on that date; and Lessor shall not be liable for any
            damages (including without limitation special or consequential
            damages) Lessee suffers as a result of such rejections. If Lessor
            does in its discretion execute a Payment Order which results in an
            overdraft in Lessee's account, Lessor shall be entitled to charge
            and Lessee shall be obligated to pay interest on such overdraft.
            Lessee's account will be liable for statutory overdraft charges
            whether or not the overdraft Payment Order is executed.

      8.    Expenses. Lessee agrees to pay Lessor's customary funds transfer
            fees as in effect from time to time and to reimburse Lessor for any
            out-of-pocket expenses incurred by Lessor. Such fees and expenses
            shall be paid in cash immediately on demand or by Lessor's debiting
            Lessee's account(s) at Lessor.

      9.    Notice of Errors. Lessee shall promptly review the transfer
            confirmation or advice mailed to Lessee by Lessor after each
            transfer and notify Lessor of any discrepancy in writing as soon as
            possible and in any event within 60 calendar days of the transfer.
            Lessee shall also promptly review and reconcile its periodic
            statements of account provided by Lessor and report any
            discrepancies to Lessor in writing within 60 calendar days after the
            statement date. Lessee expressly agrees that its failure to so
            report any such discrepancies shall relieve Lessor of any liability
            for interest on any refund to which Lessee may be entitled with
            respect to such unreported discrepancies. Statements and advices
            shall be deemed received 5 days after mailing.

      10.   Disclosure of Information. Lessee acknowledges that Lessor may be or
            become required by federal regulation to report or make information
            available concerning all or some classes of funds transfers.

      11.   Force Majeure. Lessee agrees that Lessor is not liable for any
            error, interruption, delay, or failure in transmission occasioned by
            any circumstances beyond Lessor's control including but not limited
            to discrepancies or ambiguity in any Payment Order, funds transfer
            system unavailability, weather, failure of power, other utilities or
            communication media, strikes, industrial sabotage, war, governmental
            interference, and error, delay, insolvency or unavailability of
            other receiving, intermediary or beneficiary Lessors.

      12.   Indemnity. Lessee agrees to hold Lessor harmless and indemnify
            Lessor for any and all claims, liabilities, demands, costs, expenses
            (including but not limited to attorneys' fees and disbursements),
            losses or damages of any nature whatsoever arising directly or
            indirectly from any Payment Order executed pursuant to this
            Agreement except for liability to Lessee caused by gross negligence
            or willful misconduct of Lessor. In no event shall Lessor be liable
            for any consequential or special damages.

      13.   Governing Law. This Agreement shall be governed by the internal laws
            of New York State (including without limitation Article 4A of the
            Uniform Commercial Code) and by applicable federal law and
            regulations.

All notices to Lessor shall be directed to the Manager, Commercial Loan
Operations, 3rd Floor, Manufacturers and Traders Trust Company, One Fountain
Plaza, Buffalo, New York 14203; all notices to Lessee shall be directed to
Lessee at the most recent address listed in the records of Lessor.

Termination Option, Lessor shall convey to Lessee, all of Lessor's right, title
and interest in and to the Equipment on an "as-is, where-is" basis, without
recourse or warranty except against any liens placed on the Equipment by Lessor.

The Lessee may exercise the Early Termination Option upon written notice to
Lessor given not less than ninety (90) days nor more than one hundred eighty
(180) days prior to the Early Termination Date. Such notice shall be
irrevocable. Upon Lessee's exercise of the Early Termination Option, Lessee
shall pay to Lessor all due but unpaid rent under the Equipment Schedule
together with the Option Price.

In the event that the Early Termination Option is not exercised by the Lessee in
accordance with this Rider, all of Lessee's obligations under the Equipment
Schedule will continue unaffected.

                            FUNDS TRANSFER AGREEMENT
                              SINGLE PAYMENT ORDER

To induce Lessor to execute the funds transfer payment order on the front of
this form, Lessee makes the following waivers and agrees to the following terms
and conditions.

      1.    Waiver of Lessor's Security Procedures. Lessee hereby rejects and
            waives the protection of the Lessor's customary funds transfer
            security procedures, and agrees that a request for personal
            identification in a procedure including signature comparison shall
            be deemed a commercially reasonable security procedure for purposes
            of Article 4A of the Uniform Commercial Code.

      2.    Authorization. Lessee shall supply Lessor with all information that
            Lessor requests including, but not limited to, money amounts;
            beneficiary's account number, name and Lessor; value date;
            supplemental instructions; and further evidence of the authority of
            any of Lessee's authorized representatives to issue Payment Orders
            or to do any other act contemplated under this Agreement. For
            Lessees protection, Lessor may reject any Payment Order if Lessor is
            unable to obtain satisfactory verification of the Order or its due
            authorization. If Lessee is an entity, the person signing this
            agreement certifies that he or she is duly authorized to execute
            such transaction on behalf of Lessee; and acknowledges that any
            false statement will render him or her personally liable for
            monetary damages as well as criminal penalties including substantial
            fines and imprisonment under federal and state law.

      3.    Account Number Controls. Lessee ACKNOWLEDGES RECEIPT OF NOTICE THAT
            M&T Lessor, ALL INTERMEDIARY LessorS AND BENEFICIARY'S Lessor ARE
            ENTITLED TO RELY ON THE BENEFICIARY'S ACCOUNT NUMBER AND ANY Lessor
            IDENTIFYING NUMBER AS STATED IN THE PAYMENT ORDER AS RECEIVED EVEN
            IF THE NUMBER AND NAME GIVEN FOR THE BENEFICIARY REFER TO DIFFERENT
            PERSONS OR LessorS. Lessee IS WARNED TO VERIFY ALL ACCOUNT NUMBERS
            AND Lessor NUMBERS WITH EXTRAORDINARY CARE.

      4.    Risk of Clear Text. Lessee understands that all Payment Orders are
            transmitted in Clear Text and Lessee assumes full responsibility for
            all such Payment Orders executed by Lessor at Lessee's request.

      5.    Standard of Care. Lessee agrees Lessor has no responsibility beyond
            executing the transaction requested with ordinary care, subject to
            this Agreement. Lessor shall be conclusively deemed to have
            exercised ordinary care if Lessor has followed procedures customary
            in the industry or if Lessee has not followed such procedures.

      6.    Cancellation. Lessee shall have no right to amend a Payment Order or
            to cancel it after Lessor has begun processing it. In case of Lessee
            error, Lessor has no obligation but reserves the right to attempt to
            assist Lessee to recover its funds.

      7.    Limited to Available Funds. A Payment Order is debited to Lessee's
            designated account when it is executed by Lessor. Lessee agrees that
            its Payment Orders shall not exceed the available balance in
            Lessee's account on the execution date. If Lessee's account does not
            contain sufficient available funds on that date, Lessor may reject
            any or all of Lessee's Payment Orders for that date, charge any of
            Lessee's other accounts with Lessor, or execute any one or more
            Payment Orders on that date; and Lessor shall not be liable for any
            damages (including without limitation special or consequential
            damages) Lessee suffers as a result of such rejections. If Lessor
            does in its discretion execute a Payment Order which results in an
            overdraft in Lessee's account, Lessor shall be entitled to charge
            and Lessee shall be obligated to pay interest on such overdraft.
            Lessee's account will be liable for statutory overdraft charges
            whether or not the overdraft Payment Order is executed.

      8.    Expenses. Lessee agrees to pay Lessor's customary funds transfer
            fees as in effect from time to time and to reimburse Lessor for any
            out-of-pocket expenses incurred by Lessor. Such fees and expenses
            shall be paid in cash immediately on demand or by Lessor's debiting
            Lessee's account(s) at Lessor.

      9.    Notice of Errors. Lessee shall promptly review the transfer
            confirmation or advice mailed to Lessee by Lessor after each
            transfer and notify Lessor of any discrepancy in writing as soon as
            possible and in any event within 60 calendar days of the transfer.
            Lessee shall also promptly review and reconcile its periodic
            statements of account provided by Lessor and report any
            discrepancies to Lessor in writing within 60 calendar days after the
            statement date. Lessee expressly agrees that its failure to so
            report any such discrepancies shall relieve Lessor of any liability
            for interest on any refund to which Lessee may be entitled with
            respect to such unreported discrepancies. Statements and advices
            shall be deemed received 5 days after mailing.

      10.   Disclosure of Information. Lessee acknowledges that Lessor may be or
            become required by federal regulation to report or make information
            available concerning all or some classes of funds transfers.

      11.   Force Majeure. Lessee agrees that Lessor is not liable for any
            error, interruption, delay, or failure in transmission occasioned by
            any circumstances beyond Lessor's control including but not limited
            to discrepancies or ambiguity in any Payment Order, funds transfer
            system unavailability, weather, failure of power, other utilities or
            communication media, strikes, industrial sabotage, war, governmental
            interference, and error, delay, insolvency or unavailability of
            other receiving, intermediary or beneficiary Lessors.

      12.   Indemnity. Lessee agrees to hold Lessor harmless and indemnify
            Lessor for any and all claims, liabilities, demands, costs, expenses
            (including but not limited to attorneys' fees and disbursements),
            losses or damages of any nature whatsoever arising directly or
            indirectly from any Payment Order executed pursuant to this
            Agreement except for liability to Lessee caused by gross negligence
            or willful misconduct of Lessor. In no event shall Lessor be liable
            for any consequential or special damages.

      13.   Governing Law. This Agreement shall be governed by the internal laws
            of New York State (including without limitation Article 4A of the
            Uniform Commercial Code) and by applicable federal law and
            regulations.

All notices to Lessor shall be directed to the Manager, Commercial Loan
Operations, 3rd Floor, Manufacturers and Traders Trust Company, One Fountain
Plaza, Buffalo, New York 14203; all notices to Lessee shall be directed to
Lessee at the most recent address listed in the records of Lessor.

      In consideration of the mutual agreement hereinafter set forth, the
parties do hereby mutually agree as follows:

      1. Premises. Landlord does hereby lease to Tenant and Tenant does hereby
lease from Landlord, for the term and upon the conditions hereinafter provided,
approximately 28,000 square feet of space (hereinafter referred to as the
"Demised Premises") commonly known as 832, 834, 838 and 840 North Henry Street,
Alexandria, Virginia 22314 within the North Point office building complex (the
building and land being hereinafter referred to as the "Property"), together
with a license hereinafter described to the non-exclusive use, in common with
others, of such parking spaces and other facilities designed for common use as
may be installed by Landlord. The Demised Premises are outlined in red on the
plan attached hereto marked as Exhibit A and incorporated herein by reference,
and shall be deemed to be the total square footage described herein, regardless
of actual measurement.

      2. Term. (a) The Demised Premises are leased for a term (hereinafter
referred to as the "Term") commencing on the 1st day of February, 1995 (or as
soon thereafter as Landlord shall have made the Demised Premises available for
the Tenant's use and occupancy) and ending on the 31st day of January, 1998,
unless the term shall sooner cease or expire as hereinafter provided.

            (b) Omitted.

            (c) The taking of possession of the Demised Premises shall be deemed
an acceptance of the same by Tenant.

            (d) After the lease commencement date, upon request of either party,
Landlord and Tenant shall promptly execute; acknowledge and deliver to one
another a written instrument certifying the lease commencement date and
expiration date.
<PAGE>

            (e) If Landlord is unable to deliver possession of the Demised
Premises to Tenant by reason of the holding over or retention of possession by
any tenant or occupant, the lease commencement date shall be extended for such
period of time as may be reasonably necessary to enable Landlord to evict such
tenant or occupant and to deliver possession of the Demised Premises to Tenant.

      3. Rental. (a) Tenant shall pay as rent for the Demised Premises
(hereinafter referred to as "Rent") at the office of Landlord herein designated
(or at such other place as Landlord may designate in a notice to Tenant),
without prior demand therefor and without any setoff, deduction or counterclaim
whatsoever, the following sums:

            (i) In the first lease year, commencing on February 1, 1995, the sum
of Two Hundred Sixty Thousand and Sixty Four and No/100 Dollars ($260,064.00),
payable in advance in equal monthly installments of Twenty One Thousand Six
Hundred Seventy Two and No/100 Dollars ($21,672.00);

            (ii) In the second lease year, commencing on February 1, 1996, the
sum of Two Hundred Sixty Six Thousand Four and No/100 Dollars ($266,004.00),
payable in advance in equal monthly installments of Twenty Two Thousand One
Hundred Sixty Seven and no/l00 Dollars (22,167.00);

            (iii) In the third lease year, commencing on February 1, 1997, the
sum of Two Hundred Seventy Three Thousand and No/100 Dollars ($273,000.00),
payable in advance in equal monthly installments of Twenty Two Thousand Seven
Hundred Fifty and No/1000 Dollars ($22,750.00).

      (b) If the Term of this Lease begins on a date other than the first day of
a month, Rent from such other date to the first day of the following month shall
be prorated at the rate of one-thirtieth (1/30th) of the fixed monthly Rental
for each day, payable in advance.

      4. Additional Rent. (a) Commencing with the calendar year beginning
January 1, 1996, and each subsequent calendar year or portion thereof for the
Term, Tenant agrees to pay Landlord as additional rent (hereinafter referred to
as "Additional Rent") and its pro rata share (as hereinafter defined) of any
increase in Taxes and Assessments above the Base Costs of Taxes and Assessments
(as hereinafter defined).

            (b) For purpose of this Lease:

                  (i) pro rata share shall mean forty one percent (41%)
representing the ratio that the area of the Demised Premises bears to the total
rentable area in the building.

                  (ii) "Taxes and Assessments" shall mean all taxes and
assessments and governmental charges (including personal property and real
estate taxes), whether federal, state,


                                      -2-
<PAGE>

county or municipal, and whether by taxing districts or authorities presently
taxing the Property or by others subsequently created, and any other taxes and
assessments (including franchise taxes) attributable to the Property or its
operation, whether or not directly paid by Landlord, excluding however, federal
and state taxes on income, unless such income taxes replace real estate taxes.
Taxes and Assessments shall be the amount due in cash for any year and shall not
be determined on an accrual or fiscal year basis. It is agreed that Tenant shall
be responsible for ad valorem taxes on its personal property.

                  (iii) "Base Costs of Taxes and Assessments" shall be the Costs
of Taxes and Assessments incurred in the calendar year 1995.

            (c) Landlord shall endeavor to give to Tenant on or before the first
day of April of each year a statement prepared by Landlord's certified public
accountant of the increase in the Additional Rent payment by Tenant hereunder,
but failure by Landlord to give such statement by said date shall not constitute
a waiver by Landlord of his right to require an increase in Additional Rent.
Upon receipt of the statement for the first year, Tenant shall pay, in full, the
total amount of the increase due in the first year. In addition, for the then
current year, an amount equal to 110% of any such increase shall be used as an
estimate for said current year and this amount shall be divided into twelve (12)
equal monthly installments and Tenant shall pay to Landlord concurrently with
the regular monthly Rent Payment next due following the receipt of such
statement, an amount equal to one (1) monthly installment multiplied by the
number of months from January in the calendar year which said statement is
submitted to the month of such payment, both months inclusive. Subsequent
installments shall be payable concurrently with the regular monthly Rent
payments for the balance of that calendar year and shall continue until the next
year's statement is rendered. If the next or any succeeding year results in a
greater increase in Taxes and Assessments, then upon receipt of a statement from
Landlord, Tenant shall pay a lump sum equal to such total increase over the Base
Costs of Taxes and Assessments, less the total of the monthly installments of
estimated increases paid in the previous calendar year for which comparison is
then being made; and the estimated monthly installments to be paid for the next
year, following said comparison year, shall be adjusted to reflect 110% of such
increase in the manner set forth above. If in any year the Tenant's share of
direct expenses shall be less than the preceding year, then upon receipt of
Landlord's statement, any other payment made by Tenant on the monthly
installment basis provided above shall be credited toward the next monthly Rent
falling due and the estimated monthly installments of Taxes and Assessments to
be paid shall be adjusted to reflect such lower Taxes and Assessments for the
most recent comparison year but not less than the Base Costs of Taxes and
Assessments thereof. Upon termination of this Lease, any money owed by one party
to the other shall be promptly paid.

            (d) Should this Lease commence or terminate at any time other than
the first day of a calendar year, the cost adjustment referred to in Paragraphs
4(a), 4(b) and 4(c) shall be calculated for the commencement or termination year
on a pro rata basis. Tenant shall only pay the cost adjustment for the calendar
days during which Tenant leases the Demised Premises.


                                      -3-
<PAGE>

             (e) Each statement provided by Landlord pursuant to this paragraph
shall be conclusive and binding upon Tenant unless fifteen (15) days after
receipt of the statement, Tenant shall notify Landlord that it disputes the
correctness of the statement, specifying the respects in which the statement is
claimed to be incorrect. Tenant shall then have the right to request that
Landlord provide, at Tenant's expense, an audit of its books and records
relating to the statement. Pending determination of the dispute, Tenant shall
pay within ten (10) days from notice any amounts due from Tenant in accordance
with the statement, but such payment shall be without prejudice to Tenant's
position.

      5. Omitted.

      6. Past Due Rent and Late Charges. If Tenant shall fail to pay, when the
same is due and payable, any Rent or any additional Rent, or any other amounts
or charges, such unpaid amounts shall bear interest from the due date thereof to
the date of payment as hereafter provided. In addition, Tenant shall pay to
Landlord, as a late charge, four percent (4%) of any payment required to be made
by Tenant which is more than five (5) days late.

      7. Use of Demised Premises. (a) Tenant may use and occupy the Demised
Premises solely for purposes of general office, fabrication and assembly,
engineering, research and development, testing and repair, water processing,
storage of materials, and machine shop use subject to, and in accordance with
all other provisions of this Lease and all applicable zoning and other
governmental regulations. Tenant shall not abandon or substantially abandon the
Demised Premises. Tenant shall not obstruct, interfere, or conflict with, the
rights of other tenants, or conflict with the fire laws or regulations, or with
any insurance policy upon the Property or any part thereof, or with any
statutes, rules or regulations now existing or subsequently enacted or
established by local, state or federal governments, nor shall Tenant use or
permit the Demised Premises, or any part thereof, to be used for any disorderly,
unlawful or extra hazardous purposes, nor for any purpose other than hereinabove
specified.

            (b) The Tenant shall not manufacture, store, install, discharge,
release, discard, incinerate, burn or otherwise use, introduce or dispose of any

                  (vi) any other material or substance, whether solid, gaseous
or liquid, the presence of which is prohibited by any law similar to those set
forth in this Subsection or otherwise addressing environmental or health
matters.

      (c) Notwithstanding subparagraph (b) above, nothing herein shall preclude
Tenant from conducting operations and using and disposing of substances and
materials in the normal course of its business in accordance with both federal
law and the hazardous waste permits issued and maintained with the City of
Alexandria, shown on Exhibit B, annexed hereto and incorporated herein, provided
that such substances and materials have been expressly approved by the Landlord,
which approval shall be granted in its sole and absolute discretion. All
substances used in or upon the Demised Premises shall be delivered, used,
removed, and disposed of in accordance with all applicable federal, state and
local laws. The Tenant shall indemnify the Landlord and any lender secured by
the Demised Premises for any damages, cost or expense, including attorney fees,
incurred as a result of the breach of the Tenant's covenant in this Paragraph 7.

      8. Common Areas. All common areas and facilities not within the Demised
Premises, which Tenant may be permitted to use and occupy, are to be used and
occupied under a revocable license, and if the amount of such areas shall be
diminished, Landlord shall not be subject to any liability nor shall Tenant be
entitled to any compensation or diminution or abatement of Rent, nor shall such
diminution of such areas be deemed constructive or actual eviction.

      9. Parking. Tenant shall have the right during normal business hours to
the use of its pro rata share of parking spaces on the Property. All automobile
parking areas shown on the plans for the Property shall be under the sole and
exclusive control of the Landlord. Use by all tenants, their officers, agents,

limited to, rules designating areas for employee parking, assignment of specific
spaces to any tenant, controlling of ingress and egress, locating and arranging

discretion, as is consistent with the use of the areas by all tenants. Landlord
shall have the right to grant to any tenant an exclusive revocable license to
the use of certain parking spaces, and the Tenant shall have the right to use
only those parking spaces on the Property specifically assigned to the Tenant or
designated for common use.

      10. Options To Renew. Provided that the Tenant is not in default under the

except that the Rental amount shall be increased as follows:


                                      -5-
<PAGE>

            (i) In the first option year, commencing February 1, 1998, the sum
of Two Hundred Eighty Thousand and No/l00 Dollars ($280,000.00), payable in
advance in equal monthly installments of Twenty Three Thousand Three Hundred
Thirty Three and No/100 Dollars ($23,333.00).

            (ii) In the second option year, commencing February 1, 1999, the sum
of Two Hundred Eighty Seven Thousand Four and No/100 Dollars ($287,004.00),
payable in advance in equal monthly installments of Twenty Three Thousand Nine
Hundred Seventeen and No/100 Dollars ($23,917.00).

In order the exercise each option, the Tenant must give the Landlord notice of
its intent to do so at least six (6) months prior to the expiration date of the
then current lease term.

      11. Subletting and Assignment. Tenant shall not sublet the Demised
Premises or any part thereof or transfer possession or occupancy thereof to any
person, firm or corporation or transfer or assign this lease without the prior
written consent of the Landlord, which shall not be unreasonably withheld, and
subject to Landlord's right to sublet hereinafter described, nor shall any
subletting or assignment hereof be effected by operation of law or otherwise
than by the prior written consent of the Landlord. If Tenant is a corporation,
any transfer of a majority of Tenant's issued and outstanding capital stock
shall be deemed an assignment under this paragraph. If Tenant is a partnership,
any transfer of any interest in the partnership or other change in the
composition of the partnership which results in a change in the management of
Tenant from the person(s) managing the partnership on the date hereof shall be
deemed an assignment under this paragraph. In the event Tenant desires to assign
this Lease or sublet all or any portion of the Demised Premises, Tenant shall
give to Landlord thirty (30) days written notice of Tenant's intention so to do.
Within thirty (30) days after receipt of said notice, Landlord shall have the
right to sublet the Demised Premises from Tenant at the same Rent and Additional
Rent stipulated herein, regardless of the rental rate that Tenant may otherwise
be able to obtain upon assignment or subletting to others. In the event Landlord
has not exercised its right to sublet the Demised Premises as provided above in
this paragraph, Tenant may assign this Lease or sublet all or a portion of the
Demised Premises as set forth in the notice after first obtaining the written
consent of Landlord, which consent may be withheld for reasonable cause. If
Tenant does not so assign or sublet within sixty (60) days of the original
notice to Landlord pursuant to this paragraph, then Tenant shall again be
required to comply with the notice provisions hereof, and Landlord shall again
have the right to sublet. The consent by Landlord to any assignment, transfer or
subletting to any party shall not be construed as a waiver or release of Tenant
from the terms of any covenant or obligation under this Lease, nor shall the
collection or acceptance of Rent from any such assignee, transferee, subtenant
or occupant constitute a waiver or release of Tenant of any covenant or
obligation contained in this Lease, nor shall any such assignment or subletting
be construed to relieve Tenant from giving Landlord said thirty (30) days notice
or from obtaining the consent in writing of Landlord to any future assignment or
subletting. In the event that Tenant defaults hereunder, Tenant hereby assigns
to Landlord the rent due from any subtenant of Tenant and hereby authorizes each
such subtenant to pay said rent directly to Landlord.

reasonable extension of the period of construction within the Demised Premises.

occupancy permit issued.

directly causing the loss giving rise to the claim, Tenant shall indemnify
Landlord and its agents and employees, the landlord of any underlying lease, and
the holders of any mortgages or deeds of trust on the Property and save them
harmless from and against any and all claims, actions, damages, liabilities and

extent reasonably possible the exercise of such rights shall not unreasonably
interfere with the operation of the Tenant's business.

            (d) Landlord's entrance upon the Demised Premises occasioned by this
paragraph shall not constitute an eviction of Tenant in whole or in part and the

interruption of business of Tenant, or otherwise.

                  (iii) all servicing, maintenance, repair and replacement of
electric lighting, electric service, plumbing, plumbing fixtures, supplemental
heating, ventilating and air conditioning equipment, and other mechanical and
electrical equipment within the Demised Premises, including tenant improvements
and fixtures;

                  (iv) servicing, maintenance and repair of the base building
heating, ventilating and air conditioning equipment by a qualified service
contractor; and

                  (v) trash removal service from such dumpster location or
locations on the grounds of the Property as Landlord may designate.

            (b) Provided that the Tenant is not in default under any provision
of this Lease, the Tenant has not been negligent in its use of any heating,
ventilating and air conditioning equipment, and Tenant has periodically
maintained such equipment as required herein, under a service contract with a
qualified service contractor, Landlord shall replace or rebuild any such
equipment which, as a result of normal usage and depreciation, fails to function
despite Tenant's maintenance and repair;

            (c) Any failure by Landlord to furnish the foregoing services shall
not render Landlord liable in any respect for damages to either person or
property, nor be construed as an eviction to Tenant, nor work an abatement of
Rent, nor relieve Tenant from Tenant's obligations hereunder.

      23. Insurance. (a) Tenant shall not conduct or permit to be conducted any
activity or place any equipment in or about the Demised Premises which will, in
any way, increase the rate of insurance premiums on the Property. If any
increase in the rate of insurance premiums is stated by any insurance comparty
or by the applicable Insurance Rating Bureau to be due to any activity or
equipment in or about the Demised Premises, such statement shall be conclusive
evidence that the increase in such rate is due to such activity or equipment
and, as a result thereof, Tenant shall be Liable for such increase and shall
reimburse Landlord therefor, within ten (10) days of receipt of written notice,
said sum shall be deemed to be Additional Rent.

            (b) Landlord shall insure the building, of which the Demised
Premises are a part, against damage by fire, including extended coverage, in any
amount Landlord in its sole discretion shall deem adequate, and shall maintain
such insurance throughout the term hereby demised. Tenant shall insure all of
its property in the Demised Premises against damage by fire, including extended
coverage, in an amount as shall be determined by the Landlord in consultation
with Tenant, and Tenant shall maintain such insurance throughout the term hereby
demised. In addition, Tenant shall

      26. Defaults and Remedies. (a) The following events shall be a default
(hereinafter referred to as a "Default") of Tenant under this Lease:

                  (i) Failure of Tenant to make any payment of Rent (including
Annual Increase) when due.

                  (ii) Failure of Tenant to make any payment of Additional Rent
when due.

                  (iii) Failure of Tenant to perform or comply with any
provision of this Lease to be performed or complied with by Tenant, other than
provisions for the payment of Rent or Additional Rent, where such failure shall
continue for a period of ten (10) days after written notice thereof by Landlord
to Tenant.

                  (iv) The taking of this Lease or the Demised Premises, or any
part thereof, upon execution or by other process of law directed against Tenant,
or upon or subject to any attachment at the instance of any creditor of or
claimant against Tenant, which execution or attachment shall not be discharged
or disposed of within thirty (30) days after the levy thereof.

                  (v) If Tenant fails to take possession of the Demised Premises
within a reasonable period of time after the lease commencement of the Term of
this Lease or substantially vacates or abandons the Demised Premises prior to
the normal expiration of the term.

                  (vi) The circumstance of Tenant, or any guarantor of Tenant's
obligation hereunder, in financial difficulties as evidenced by (1) its
admitting in writing its inability to pay its debts generally as they become
due, or (2) its filing a petition in bankruptcy or for reorganization or the
adoption of an arrangement under the Bankruptcy Act (as now or hereafter
existing), or an answer or other pleading admitting the material allegations of
such a petition or seeking, consenting to or acquiescing in the relief provided
for under such Act, or (3) its making an assignment of all or a substantial part
of its property for the benefit of its creditors or (4) its seeking or
consenting to or acquiescing in the appointment of a receiver or trustee for all
or a substantial part of its property or of the Demised Premises, or (5) its
being adjudicated a bankrupt or insolvent, or (6) the entry of a court order
without its consent, which order shall not be vacated, set aside or stayed
within sixty (60) days from the date of entry, appointing a receiver or trustee
for all or a substantial part of its property or approving a petition filed
against it for the effecting of an arrangement in bankruptcy or for a
reorganization pursuant to the Bankruptcy Act or for any other judicial
modification or alteration of the rights of creditors.

            (b) The provisions of this paragraph shall apply notwithstanding the
payment by Tenant of the security deposit and/or the continued willingness and
ability of Tenant to pay Rent and otherwise perform hereunder. The receipt by
Landlord of payments of Rent, as such, accruing subsequent to the time of
Tenant's default under this paragraph and even though Landlord may have actual
notice of the occurrence of an event of Default under this paragraph shall not
be deemed a waiver by Landlord of the provisions of this paragraph.


                                      -14-
<PAGE>

            (c) Upon the occurrence of a Default, Landlord shall have the right
at its election, then or at any time thereafter either:

                  (i) To give Tenant written notice of Landlord's intent to
terminate this Lease on the date of the notice or on any later date, specified
in the notice, and on such date Tenant's right to possession of the Demised
Premises shall cease and this Lease shall thereupon be terminated; or

                  (ii) to re-enter without demand or notice and to take
possession of all or any part of the Demised Premises and expel Tenant and those
claiming through Tenant, and remove the property of Tenant and any other person,
either by summary proceedings, by action at law or in equity, by force without
due process of law, or by any other means, without being deemed guilty of
trespass or liable for prosecution or damages therefor, and without prejudice to
any remedies for nonpayment or late payment of Rent or breach of covenant. If
Landlord elects to reenter under this provision, Landlord may terminate this
Lease, or, from time to time, without terminating this Lease, may relet all or
any part of the Demised Premises as agent for Tenant for such term or terms and
at such rental and upon such other terms and conditions as Landlord may deem
advisable in its sole and absolute discretion, with the right to make
alterations and repairs to the Demised Premises. No such reentry or taking of
possession of the Demised Premises by Landlord shall be construed as an election
on Landlord's part to terminate this Lease unless a written notice of such
intention is given to Tenant or unless the termination be decreed by a court of
competent jurisdiction at the instance of Landlord. Nothing herein shall be
construed to require the Landlord to mitigate damages.

            (d) If Landlord terminates this Lease pursuant to the preceding
subparagraph, Tenant shall remain liable (in addition to accrued liabilities)
for (i) Rent, Additional Rent and any other sums provided for in this Lease
until the date this Lease would have expired had such termination not occurred,
and any and all expenses (including attorney's fees, disbursements and brokerage
fees) incurred by Landlord in reentering and repossessing the Demised Premises,
in making good any Default of Tenant, in painting, altering, repairing or
dividing the Demised Premises, in protecting and preserving the Demised Premises
by use of watchmen and caretakers, and in reletting the Demised Premises, and
any and all expenses which Landlord may incur during the occupancy of any new
tenant; less (ii) the net proceeds of any reletting prior to the date this Lease
would have expired if it had not been terminated. Tenant agrees to pay to
Landlord the difference between items (i) and (ii) above for each month during
the Term, at the end of each such month. Any suit brought by Landlord to enforce
collection of such difference for any one month shall not prejudice Landlord's
right to enforce the collection of any difference for any subsequent month. In
addition to the foregoing, and without regard to whether this Lease has been
terminated, Tenant shall pay to Landlord all costs incurred by Landlord,
including reasonable attorney's fees, with respect to any lawsuit or action
instituted or taken by Landlord to enforce the provisions of this Lease.
Tenant's liability shall survive the institution of summary proceedings and the
issuance of any writ of restitution thereunder.


                                      -15-
<PAGE>

            (e) If Landlord terminates this Lease, Landlord shall have the
right, at any time, at its option, to require Tenant to pay to Landlord on
demand, as liquidated and agreed final damages in lieu of Tenant's liability
hereunder, the Rent, Additional Rent and all other charges which would have been
payable from the date of such demand to the date when this Lease would have
expired if it had not been terminated, (minus the fair rental value negotiated
in good faith with another tenant of the Demised Premises for the same period,
if any). If the Demised Premises shall have been relet for all or part of the
remaining balance of the Term by Landlord after a Default but before
presentation of proof of such liquidated damages, the amount of rent reserved
upon such reletting shall be deemed the fair rental value of the Demised
Premises for purposes of the foregoing determination of liquidated damages. Upon
payment of such liquidated and agreed final damages, Tenant shall be released
from all further liability under this Lease with respect to the period after the
date of demand.

            (f) Tenant, on its own behalf and on behalf of all persons claiming
through Tenant, including all creditors does hereby waive any and all rights and
privileges, so far as is permitted by law, which Tenant and all such persons
might otherwise have under any present or future law (i) to the service of any
notice of intention to reenter which may otherwise be required to be given, (ii)
to redeem the Demised Premises, (iii) to reenter or repossess the Demised
Premises, or (iv) to restore the operation of this Lease, with respect to any
dispossession of Tenant by judgment or warrant of any court or otherwise,
whether such dispossession, reentry, expiration or termination be by operation
of law or pursuant to the provisions of this Lease.

            (g) In the event of any breach by Tenant or any person or persons
claiming through Tenant of any of the provisions contained in this Lease,
Landlord shall be entitled to enjoin such breach and shall have the right to
invoke any right or remedy allowed at law or otherwise as if reentry, summary
proceedings or other specific remedies were not provided for in this Lease.

            (h) Landlord shall, to the extent permitted by law, have (in
addition to all other rights) a right of distress for Rent and Additional Rent
and a lien on all Tenant's personal property as security for all adjusted Rent,
Additional Rent and any other sums payable under this Lease.

            (i) If Tenant defaults in the making of any payment to a third party
or in the doing of any act herein required to be made or done by Tenant, then
after ten (10) days notice from Landlord (except in the event of nonpayment of
Rent or Additional Rent, for which no notice is required), Landlord may, but
shall not be required to, make such payment or do such act, and the amount and
the expense thereof, if made or done by Landlord, with interest thereon at the
rate of three hundred (300) base points over the prime rate of Crestar Bank,
Richmond, Virginia, or its successor, but not to exceed the highest lawful rate,
from the date paid by Landlord, shall be paid by Tenant to Landlord and shall
constitute Additional Rent hereunder due and payable with the next monthly
installment of Rent; but the making of such payment or the doing of such act by
Landlord shall not operate to cure such Default or to estop Landlord from the
pursuit of any remedy to which Landlord would otherwise be entitled.


                                      -16-
<PAGE>

            (j) All rights and remedies of Landlord under this Lease shall be
cumulative and shall not be exclusive of any other rights and remedies provided
to Landlord now or hereafter under law or under this Lease.

      27. Waiver. If under the provisions hereof Landlord shall institute
proceedings and a compromise or settlement thereof shall be made, the same
shall not constitute a waiver of any covenant herein contained nor of any of
Landlord's rights hereunder. No waiver by Landlord of any breach of any
covenant, condition or agreement herein contained shall operate as a waiver of
such covenant, condition or agreement itself, or of any subsequent breach
thereof. No payment by Tenant or receipt by Landlord of a lesser amount than the
monthly installments of Rent herein stipulated shall be deemed to be other than
on account of the earliest stipulated Rent, nor shall any endorsement or
statement on any check or letter accompanying a check for payment of Rent or
Additional Rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of such Rent or Additional Rent or to pursue any other remedy provided
in this Lease. No reentry by Landlord, and no acceptance by Landlord of keys
from Tenant, shall be considered an acceptance of a surrender of this Lease.

      28. Subordination. This Lease is subject and subordinate to all ground or
underlying leases and to all mortgages and/or deeds of trust which may now or
hereafter affect such leases or the Property and to all renewals, modifications,
consolidations, replacements and extensions thereof. This clause shall be
self-operative and no further instrument of subordination shall be required by
any mortgagee or trustee. In confirmation of such subordination, Tenant shall
execute promptly any certificate that the Landlord may request. Tenant hereby
constitutes and appoints Landlord the Tenant's attorney-in-fact to execute any
such certificate or certificates for an on behalf of Tenant. Notwithstanding the
foregoing, the party secured by any such deed of trust shall have the right to
recognize this Lease and, in the event of any foreclosure sale under such deed
of trust, or deed in lieu thereof, this Lease shall continue in full force and
effect at the option of the party secured by such deed of trust or the purchaser
under any such foreclosure sale; Tenant covenants and agrees that it shall at
the written request of the party secured by any such deed of trust, execute,
acknowledge and deliver any instrument that has for its purpose and effect the
subordination of this Lease to the lien of said deed of trust and the attornment
of the Tenant to such party. At the option of any landlord under any ground or
underlying lease to which this Lease is now or may hereafter become subject or
subordinate, Tenant agrees that neither the cancellation nor termination of such
ground or underlying lease shall by operation of law or otherwise, result in
cancellation or termination of this Lease or the obligations of the Tenant
hereunder, and Tenant covenants and agrees to attorn to such landlord or to any
successor to Landlord's interest in such ground or underlying lease and in that
event, this Lease shall continue as a direct lease between Tenant herein and
such landlord or its successor; and, in any case, such landlord or successor
under such ground or underlying lease shall not be bound by any prepayment on
the part of Tenant of any Rent for more than one month in advance, so that Rent
shall be payable under this Lease in accordance with its terms, from the date of
the termination of the ground or underlying lease, as if such prepayment had not
been made. Such landlord or successor under such ground or underlying lease
shall not be bound by this Lease or any amendment or modification of this Lease
unless, prior to the termination of such ground or


                                      -17-
<PAGE>

underlying lease, a copy of this Lease or amendment or modification thereof, as
the case may be, shall have been delivered to such landlord or successor.

      29. Estoppel Certificates. Tenant agrees, at any time and from time to
time, upon not less than five (5) days prior notice by Landlord, to execute,
acknowledge and deliver to Landlord a statement in writing in such form as
Landlord may request, (i) certifying that this Lease is unmodified (or if
modified, stating the modifications) and in full force and effect (or if not in
full force and effect, the reasons therefor), (ii) stating the dates to which
the Rent, Additional Rent and other charges hereunder have been paid by Tenant,
(iii) stating whether or not to the best knowledge of Tenant, Landlord is in
default in the performance of any covenant, agreement or condition contained in
this Lease, and if so, specifying each such default of which Tenant may have
knowledge, and (iv) stating the address to which notices to Tenant should be
sent. Any such statement delivered pursuant hereto may be relied upon by any
owner of the Property, any prospective purchaser of the Property, any mortgagee
or prospective mortgagee of the Property, any prospective assignee of any such
mortgagee, or any lessor or prospective lessor of the land which is a part of
the Property.

      30. No Recourse to Landlord. The obligations of Landlord under this Lease
do not constitute personal obligations of the individual partners, directors,
officers, or shareholders of Landlord, and Tenant shall look solely to the
Property of which the Demised Premises are a part and to no other assets of the
Landlord or the holders of any mortgages or deeds of trust on the Property for
satisfaction of any liability in respect of this Lease and shall not seek
recourse against the individual partners, directors, officers or shareholders of
Landlord or the holders of any mortgages or deeds of trust on the Property or
any of their personal assets for such satisfaction.

      31. Holding Over. If Tenant shall, with the knowledge and consent of
Landlord, continue to remain in the Demised Premises after the expiration of the
Term of this Lease and any extensions thereof, then and in such event, Tenant
shall, by virtue of this agreement become a tenant by the month at a monthly
rental equal to one hundred twenty percent (120%) of the monthly installment of
Rent agreed by the Tenant to be paid as aforesaid, commencing said monthly
tenancy with the first day next after the end of the Term above demised. Tenant
shall give to Landlord at least thirty (30) days written notice of any intention
to quit the Demised Premises, and Tenant shall be entitled to thirty (30) days
written notice to quit the Demised Premises, except in the event of non-payment
of Rent or Additional Rent or of the breach of any other covenant by Tenant, in
which event Tenant shall not be entitled to any notice to quit, the usual thirty
(30) days notice to quit being hereby expressly waived; provided, however, that
in the event that Tenant shall hold over after the expiration of the Term hereby
created, and if Landlord shall desire to regain possession of the Demised
Premises promptly at the expiration of the Term aforesaid, then at any time
prior to Landlord's acceptance of Rent from Tenant as a monthly tenant
hereunder, Landlord, at it option, may forthwith reenter and take possession of
the Demised Premises without process, or by any legal process in force.


                                      -18-
<PAGE>

      32. Submission of Lease. The submission of this Lease for examination by
Tenant does not constitute a reservation of or option for the Demised Premises,
and this Lease shall become effective as a lease only upon execution and
delivery thereof by Landlord and Tenant.

      33. Covenant of Landlord. Landlord covenants that it has the right to make
this Lease, and that if Tenant shall pay the Rent and Additional Rent and shall
perform all of Tenant's obligation under this Lease, Tenant shall, during the
term hereof, freely, peaceably and quietly occupy and enjoy the full possession
of the Demised Premises without molestation or hindrance by Landlord or any
party claiming through or under Landlord, subject, however, to the underlying
lease, mortgages and deeds of trust described in Paragraph 28 and except as
otherwise provided herein. The term "Landlord" as used herein shall mean solely
the owner of Landlord's interest in the Property, whoever that may be at the
relevant time, so that in the event of any sale or transfer of Landlord's
interest in the Property, any prior Landlord shall be freed and relieved of all
covenants and obligations of Landlord hereunder.

      34. Force Majeure. If Landlord, as the result of any (i) strikes,
lockouts, or labor disputes; (ii) inability to obtain labor, materials, fuel,
electricity, services or reasonable substitutes therefore; (iii) acts of God,
civil commotion, fire or other casualty; (iv) governmental action of any kind;
or (v) other conditions similar to those enumerated above beyond Landlord's
reasonable control, fails punctually to provide any service or to perform any
obligation on its part to be performed hereunder, then, unless otherwise
expressly provided, such failure shall be excused and shall not be a breach
hereunder, but only to the extent occasioned by such event. In the event,
however, that any such event shall prevent Landlord's performance for a period
longer than sixty (60) consecutive days, the Tenant shall have the right to
terminate this Lease.

      35. Omitted.

      36. Omitted.

      37. Waiver of Trial by Jury. Tenant hereby waives all right to trial by
jury in any claim, action, proceeding or counterclaim by either Landlord or
Tenant against each other on any matters arising out of or in any way connected
with this Lease, the relationship of Landlord and Tenant, and/or Tenant's use or
occupancy of the Demised Premises.

      38. Attorney's Fees. If, in the event of a default by Tenant, Landlord
places the enforcement of this Lease, or any part thereof, or the collection of
any Rent or Additional Rent due, or to become due hereunder, or recovery of the
possession of the Demised Premises in the hands of an attorney, or files suit
upon the same, Tenant agrees to pay Landlord's attorney's fees.

      39. Brokers. Landlord and Tenant each represent and warrant that neither
of them has employed any broker in carrying on the negotiations relating to this
Lease. Landlord shall indemnify and hold Tenant harmless, and Tenant shall
indemnify and hold Landlord harmless, from and against


                                      -19-
<PAGE>

any claim for brokerage or other commission arising from or out of any breach of
the foregoing representation and warranty.

      40. Notices. All notices or other communications hereunder shall be in
writing and shall be deemed duly given if delivered in person or sent by
certified or registered mail, return receipt requested, first class, postage
prepaid, (i) if to Landlord, at Suite 200, 1201 E. Abingdon Drive, Alexandria,
Virginia 22314, and (ii) if to Tenant at 500 Pendleton Street, Alexandria,
Virginia 22314, unless notice of a change of address is given pursuant to the
provisions of this paragraph.

      41. Miscellaneous. (a) This Lease and the Exhibits attached hereto contain
and embody the entire agreement of the parties hereto and no representations,
inducements, or agreements, oral or otherwise, between Landlord and Landlord's
agents and Tenant not contained in this Lease and Exhibits shall be of any force
or effect. This Lease may not be modified, changed or terminated in whole or in
part in any manner other than by an agreement in writing duly signed by both
parties hereto.

            (b) The terms, covenants and conditions hereof shall be binding upon
and inure to the permitted successors in interest and assigns of the parties
hereto. Landlord may freely and fully assign its interest hereunder.

            (c) If any provision of this Lease or the application thereof to any
person or circumstances shall to any extent be held void, unenforceable or
invalid, then the remainder of this Lease or the application of such provision
to persons or circumstances other than those as to which it is held void,
unenforceable or invalid shall not be affected thereby, and each provision of
this Lease shall be valid and enforceable to the fullest extent permitted by
law.

            (d) Tenant shall not record this Lease without the written consent
of Landlord, which may be given or denied in Landlord's sole discretion. If
Landlord consents to such recordation, the cost thereof shall be paid by Tenant.

            (e) The captions and headings throughout this Lease are for
convenience and reference only and the words contained therein shall in no way

the interpretation, construction or meaning of any provision of or the scope of
intent of this Lease nor in any way affect this Lease.

            (f) Nothing contained in this Lease shall be deemed or construed to
create a partnership or joint venture of or between Landlord and Tenant, or to
create any other relationship between the parties hereto other than that of
Landlord and Tenant.

the masculine form, the plural shall be substituted for singular number and vice
versa in any place or places herein in which the context may require such
substitute or substitution.

<PAGE>

            (h) This Lease is to be construed under the laws of the jurisdiction
in which the Property is located.

      42. Tenant Improvement Allowance. The Landlord shall provide an allowance
of Forty Thousand and No/100 Dollars ($40,000.00) to the Tenant for heating and
air conditioning improvements in 840 North Henry Street, and any other tenant
improvements in that bay as the Landlord may approve, which shall be paid upon
completion of construction or installation thereof. The heating and air
conditioning improvements shall be zoned within the bay, and the Landlord shall
have the right to approve the plans therefore, which shall not be unreasonably
withheld. The cost of such improvements shall be paid upon completion of
construction or installation thereof. The Landlord reserves the right to the tax
depreciation for all such improvements.

      43. Authority of Landlord and Tenant. Each individual executing this Lease
on behalf of Landlord and Tenant represents and warrants that he is duly
authorized to execute and deliver this Lease on behalf of Landlord or Tenant in
accordance with a partnership agreement or a duly adopted resolution of the

                                 LEASE AGREEMENT

      THIS LEASE is made as of the 14th day of August, 1996 by and between NORTH
POINT ASSOCIATES LIMITED PARTNERSHIP, a Virginia limited partnership
(hereinafter referred to as "Landlord") and COMMONWEALTH SCIENTIFIC CORPORATION,
a Virginia corporation, (hereinafter referred to as "Tenant").

                                   WITNESSETH:

            In consideration of the mutual agreement hereinafter set forth, the
parties do hereby mutually agree as follows:

      1. Premises. Landlord does hereby lease to Tenant and Tenant does hereby
lease from Landlord, for the term and upon the conditions hereinafter provided,
approximately 4,250 square feet of space (hereinafter referred to as the
"Demised Premises") commonly known as 828 North Henry Street, Alexandria,
Virginia 22314 within the North Point office building complex (the building and
land being hereinafter referred to as the "Property"), together with a license
hereinafter described to the non-exclusive use, in common with others, of such
parking spaces and other facilities designed for common use as may be installed
by Landlord. The Demised Premises are outlined in red on the plan attached
hereto marked as Exhibit A and incorporated herein by reference, and shall be
deemed to be the total square footage described herein, regardless of actual
measurement.

      2. Term. (a) The Demised Premises are leased for a term (hereinafter
referred to as the "Term") commencing on the 15th day of September, 1996 (or as
soon thereafter as Landlord shall have made the Demised Premises available for
the Tenant's use and occupancy) and ending on the 14th day of September, 2001,
unless the term shall sooner cease or expire as hereinafter provided.

            (b) Omitted.

            (c) The taking of possession of the Demised Premises shall be deemed
an acceptance of the same by Tenant.
<PAGE>

            (d) After the lease commencement date, upon request of either party,
Landlord and Tenant shall promptly execute, acknowledge and deliver to one
another a written instrument certifying the lease commencement date and
expiration date.

            (e) If Landlord is unable to deliver possession of the Demised
Premises to Tenant by reason of the holding over or retention of possession by
any tenant or occupant, the lease commencement date shall be extended for such
period of time as may be reasonably necessary to enable Landlord to evict such
tenant or occupant and to deliver possession of the Demised Premises to Tenant.

      3. Rental. (a) Tenant shall pay as rent (hereinafter referred to as
"Rent") for the Demised Premises the sum of Forty Thousand Three Hundred Eighty
Dollars ($40,380.00.00) per annum, payable in equal monthly installments of
Three Thousand Three Hundred Sixty Five Dollars ($3,365.00), the first
installment payable on the execution of this Agreement and the remaining
installments payable in advance on the first day of each and every month
beginning October 1, 1996 at the office of Landlord herein designated (or at
such other place as Landlord may designate in a notice to Tenant), without prior
demand therefor and without any set off, deduction or counterclaim whatsoever.

      4. Additional Rent. (a) Tenant shall pay Landlord as additional rent
(hereinafter referred to as "Additional Rent") its pro rata share (as
hereinafter defined) of Taxes and Assessments and Common Area Maintenance
Expenses (as hereinafter defined).

            (b) For purpose of this Lease:

                  (i) pro rata share shall mean six and two tenths percent
(6.2%) representing the ratio that the area of the Demised Premises bears to the
total rentable area in the building.

                  (ii) "Taxes and Assessments" shall mean all taxes and
assessments and governmental charges (including personal property and real
estate taxes), whether federal, state, county or municipal, and whether by
taxing districts or authorities presently taxing the Property or by others
subsequently created, and any other taxes and assessments (including franchise
taxes) attributable to the Property or its operation, whether or not directly
paid by Landlord, excluding however, federal and state taxes on income, unless
such income taxes replace real estate taxes. Taxes and Assessments shall be the
amount due in cash for any year and shall not be determined on an accrual or
fiscal year basis. It is agreed that Tenant shall be responsible for ad valorem
taxes on its personal property.

                  (iii) "Common Area Maintenance Expenses" shall mean the cost
of maintenance and operation of the common areas of the Property, which shall
include without limitation the costs of insuring the Property for all hazard
loss and liability coverage, and the cost and upkeep of all parking and common
areas, removal of litter and debris from the common areas (excluding, however,
tenant trash dumpster service, which shall be the responsibility of each


                                        2
<PAGE>

respective tenant), maintenance and utility expense of any common area lighting,
snow removal, landscaping and any other similar expense.

            (c) Landlord shall endeavor to give to Tenant on or before the first
day of April of each year a statement prepared by Landlord's certified public
accountant of the increase in the Additional Rent payment by Tenant hereunder,
but failure by Landlord to give such statement by said date shall not constitute
a waiver by Landlord of his right to require an increase in Additional Rent.
Upon the commencement of the Lease, Tenant shall pay with its Rent in advance in
monthly installments the Additional Rent based upon the Landlord's budget for
such Costs of Taxes and Assessments and Common Area Maintenance Expenses for
that calendar year. At the commencement of the next calendar year, the Tenant
shall pay an amount equal to 110% of the Additional Rent payable each month of
the preceding calendar year, which amount shall be used as an estimate for said
current year. If the actual Costs of Taxes and Assessments and Common Area
Maintenance Expenses exceeds in any calendar year the budget estimate of the
Landlord, then upon receipt of a statement from Landlord, Tenant shall pay a
lump sum equal to its pro rata share of such total amount of the Costs of Taxes
and Assessments and Common Area Maintenance Expenses, less the total of the
monthly installments of estimated Costs of Taxes and Assessments and Common Area
Maintenance Expenses paid in previous calendar year for which comparison is then
being made; and the estimated monthly installments to be paid for the next year
following said comparison year, shall be adjusted to reflect 110% of such actual
amount in the manner set forth above. If in any year the Tenant's share of
direct expenses shall be less than the preceding year, then upon receipt of
Landlord's statement, any other payment made by Tenant on the monthly
installment basis provided above shall be credited toward the next monthly Rent
falling due and the estimated monthly installments of Taxes and Assessments and
Common Area Maintenance Expenses to be paid shall be adjusted to reflect such
lower amount for the most recent comparison year. Upon termination of this
Lease, any money owed by one party to the other shall be promptly paid

            (d) Should this Lease commence or terminate at any time other than
the first day of a calendar year, the cost adjustment referred to in Paragraphs
4(a), 4(b) and 4(c) shall be calculated for the commencement or termination year
on a pro rata basis. Tenant shall only pay the cost adjustment for the calendar
days during which Tenant leases the Demised Premises.

            (e) Each statement provided by Landlord pursuant to this paragraph
shall be conclusive and binding upon Tenant unless fifteen (15) days after
receipt of the statement, Tenant shall notify Landlord that it disputes the
correctness of the statement, specifying the respects in which the statement is
claimed to be incorrect. Tenant shall then have the right to request that
Landlord provide, at Tenant's expense, an audit of its books and records
relating to the statement. Pending determination of the dispute, Tenant shall
pay within ten (10) days from notice any amounts due from Tenant in accordance
with the statement, but such payment shall be without prejudice to Tenant's
position.

      5. Rent Adjustment. (a) In addition to the Rent and Additional Rent
hereinabove set forth, it is understood and agreed that the basic monthly Rent
of $3,365.00______ hereinabove set forth shall be increased each subsequent
lease year following the first lease year during the Term


                                        3
<PAGE>

of this Lease on the first day of each such lease year which is hereby
designated September 15, by an amount (hereinafter, the "Annual Increase" and
which shall be deemed to be Rent herein) measured by 30% of any increase in the
United States Bureau of Labor Statistics, Consumer Price Index for All Urban
Wage Earners, All Items for Washington, D. C. SMSA (1967 = 100) (hereinafter
referred to as the "Index"). Such Annual Increase, if any, shall be computed as
follows:

                  The basic monthly Rent shall be multiplied by a fraction, the
            numerator of which shall be the most recently published monthly
            Index preceding the first day of the lease year for which such
            annual adjustment is to be made, and the denominator of which
            fraction shall be the corresponding monthly Index immediately
            preceding the commencement date of the term of this Lease. This will
            yield an "adjusted basic monthly Rent". The basic monthly Rent shall
            be subtracted and the difference multiplied by 30%; which shall be
            deemed the monthly Annual Increase to be added to the basic monthly
            Rent.

            (b) If such Index shall be discontinued with no successor or
comparable successor Index, the parties shall attempt to agree upon a substitute
formula. If the parties are unable to agree upon a substitute formula, then the
matter shall be determined by arbitration in accordance with the rules of the
American Arbitration Association then prevailing with the understanding that it
is the intent of the parties that the Rent shall be adjusted based on the
components for the current Index to the extent possible.

      6. Past Due Rent and Late Charges. If Tenant shall fail to pay, when the
same is due and payable, any Rent or any additional Rent, or any other amounts
or charges, such unpaid amounts shall bear interest from the due date thereof to
the date of payment as hereafter provided. In addition, Tenant shall pay to
Landlord, as a late charge, four percent (4%) of any payment required to be made
by Tenant which is more than five (5) days late.

      7. Use of Demised Premises. (a) Tenant may use and occupy the Demised
Premises solely for purposes of general office, fabrication and assembly,
engineering, research and development, testing and repair, water processing,
storage of materials, and machine shop use subject to, and in accordance with
all other provisions of this Lease and all applicable zoning and other
governmental regulations. Tenant shall not abandon or substantially abandon the
Demised Premises. Tenant shall not obstruct, interfere, or conflict with, the
rights of other tenants, or conflict with the fire laws or regulations, or with
any insurance policy upon the Property or any part thereof, or with any
statutes, rules or regulations now existing or subsequently enacted or
established by local, state or federal governments, not shall Tenant use or
permit the Demised Premises, or any part thereof, to be used for any disorderly,
unlawful or extra hazardous purposes, nor for any purpose other than hereinabove
specified.


                                       4
<PAGE>

            (b) The Tenant shall not manufacture, store, install, discharge,
release, discard, incinerate, burn or otherwise use, introduce or dispose of any
of the following substances on the Property, in the Demised Premises, into or
through the sewer, drainage system, ground, or the air:

                  (i) any "hazardous waste" as defined by the Resource
Conservation and Recovery Act of 1976, as amended from time to time, and
regulations promulgated thereunder;

                  (ii) any "hazardous substance" as defined by the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended from
time to time, and regulations promulgated thereunder;

                  (iii) any "hazardous waste" or "hazardous substance" as may be
defined by any applicable local, county, state, commonwealth or other federal
law, as amended from time to time, and regulations promulgated thereunder;

                  (iv) asbestos or asbestos containing material;

                  (v) polychlorinated biphenyls in concentrations greater than
50 parts per million;

                  (vi) any other material or substance, whether solid, gaseous
or liquid, the presence of which is prohibited by any law similar to those set
forth in this Subsection or otherwise addressing environmental or health
matters.

         (c) Notwithstanding subparagraph (b) above, nothing herein shall
preclude Tenant from conducting operations and using and disposing of substances
and materials in the normal course of its business in accordance with both
federal law and the hazardous waste permits issued and maintained with the City
of Alexandria, shown on Exhibit B, annexed hereto and incorporated herein,
provided that such substances and materials have been expressly approved by the
Landlord, which approval shall be granted in its sole and absolute discretion.
All substances used in or upon the Demised Premises shall be delivered, used,
removed, and disposed of in accordance with all applicable federal, state and
local laws. The Tenant shall indemnify the Landlord and any lender secured by
the Demised Premises for any damages, cost or expense, including attorney fees,
incurred as a result of the breach of the Tenant's covenant in this Paragraph 7.

      8. Common Areas. All common areas and facilities not within the Demised
Premises, which Tenant may be permitted to use and occupy, are to be used and
occupied under a revocable license, and if the amount of such areas shall be
diminished, Landlord shall not be subject to any liability nor shall Tenant be
entitled to any compensation or diminution or abatement of Rent, nor shall such
diminution of such areas be deemed constructive or actual eviction.

      9. Parking. Tenant shall have the right during normal business hours to
the use of its pro rata share of parking spaces on the Property. All automobile
parking areas shown on the plans for the Property shall be under the sole and
exclusive control of the Landlord. Use by all


                                        5
<PAGE>

tenants, their officers, agents, employees and visitors, shall be subject to
reasonable rules for the use thereof which may from time to time be promulgated
by Landlord, including, but not limited to, rules designating areas for employee
parking, assignment of specific spaces to any tenant, controlling of ingress and
egress, locating and arranging spaces, and generally maintaining the parking lot
in the manner, in Landlord's discretion, as is consistent with the use of the
areas by all tenants. Landlord shall have the right to grant to any tenant an
exclusive revocable license to the use of certain parking spaces, and the Tenant
shall have the right to use only those parking spaces on the Property
specifically assigned to the Tenant or designated for common use.

      10. Omitted.

      11. Subletting and Assignment. Tenant shall not sublet the Demised
Premises or any part thereof or transfer possession or occupancy thereof to any
person, firm or corporation or transfer or assign this lease without the prior
written consent of the Landlord, which shall not be unreasonably withheld, and
subject to Landlord's right to sublet hereinafter described, nor shall any
subletting or assignment hereof be effected by operation of law or otherwise
than by the prior written consent of the Landlord. If Tenant is a corporation,
any transfer of a majority of Tenant's issued and outstanding capital stock
shall be deemed an assignment under this paragraph. If Tenant is a partnership,
any transfer of any interest in the partnership or other change in the
composition of the partnership which results in a change in the management of
Tenant from the person(s) managing the partnership on the date hereof shall be
deemed an assignment under this paragraph. In the event Tenant desires to assign
this Lease or sublet all or any portion of the Demised Premises, Tenant shall
give to Landlord thirty (30) days written notice of Tenant's intention so to do.
Within thirty (30) days after receipt of said notice, Landlord shall have the
right to sublet the Demised Premises from Tenant at the same Rent and Additional
Rent stipulated herein, regardless of the rental rate that Tenant may otherwise
be able to obtain upon assignment or subletting to others. In the event Landlord
has not exercised its right to sublet the Demised Premises as provided above in
this paragraph, Tenant may assign this Lease or sublet all or a portion of the
Demised Premises as set forth in the notice after first obtaining the written
consent of Landlord, which consent may be withheld for reasonable cause. If
Tenant does not so assign or sublet within sixty (60) days of the original
notice to Landlord pursuant to this paragraph, then Tenant shall again be
required to comply with the notice provisions hereof, and Landlord shall again
have the right to sublet. The consent by Landlord to any assignment, transfer or
subletting to any party shall not be construed as a waiver or release of Tenant
from the terms of any covenant or obligation under this Lease, nor shall the
collection or acceptance of Rent from any such assignee, transferee, subtenant
or occupant constitute a waiver or release of Tenant of any covenant or
obligation contained in this Lease, nor shall any such assignment or subletting
be construed to relieve Tenant from giving Landlord said thirty (30) days notice
or from obtaining the consent in writing of Landlord to any future assignment or
subletting. In the event that Tenant defaults hereunder, Tenant hereby assigns
to Landlord the rent due from any subtenant of Tenant and hereby authorizes each
such subtenant to pay said rent directly to Landlord.

      12. Upkeep of Demised Premises and Surrender. (a) Tenant shall keep the
Demised Premises and the fixtures and equipment therein in clean, safe and
sanitary condition, shall take good care


                                        6
<PAGE>

thereof, and shall suffer no waste or injury thereto. Tenant shall make all
repairs to the Demised Premises caused by any negligent act or omission of
Tenant, or its employees or invitee.

            (b) Tenant shall provide at its expense (i) periodic maintenance,
including the replacement of filters as often as may be necessary, to all base
building heating, ventilating and air conditioning equipment, and (ii) servicing
of such equipment by a qualified service contractor at least twice a year
(spring and fall) in accordance with manufacture's maintenance standards.

            (c) The Landlord shall have the right to install a security light
upon the exterior of the Demised Premises and to connect it to the Tenant's
electrical service. In such event Tenant at its expense shall provide electric
current to such fixture.

            (d) Tenant shall maintain, replace and repair any plate glass in or
about the walls, doors or windows of the Demised Premises.

            (e) Tenant shall at the expiration or other termination of the Term
of this Lease, surrender and deliver up the Demised Premises, broom clean, in
the same order and condition as the same now is or shall be in at the
commencement of the Term hereof, ordinary wear and tear excepted. Upon such
termination of this Lease, Landlord shall have the right to reenter and resume
possession of the Demised Premises.

      13. Alterations. (a) Tenant shall not make any alterations, installations,
changes, replacements, additions or improvements (structural or otherwise) in or
to the Demised Premises or any part thereof without the prior written consent of
Landlord.

            (b) The Tenant shall provide the Landlord in timely manner with
complete working drawings of any improvements or alterations within the Demised
Premises approved by the Tenant. Any such improvements or alterations shall be
constructed in a reasonable period of time after receipt of such working
drawings by the Landlord at the expense of Tenant, unless the Landlord expressly
waives its right to perform such construction. Any revision or modification to
the approved drawings after commencement of construction shall be grounds for a
reasonable extension of the period of construction within the Demised Premises.
In the event that the Tenant shall fail to provide drawings which it has
approved in sufficient time to permit completion of construction within the
Demised Premises prior to the lease commencement date, the lease commencement
date shall not be extended, and Tenant shall take possession of the Demised
Premises and commence rental payments as otherwise provided herein, without
abatement of any kind, even though construction may not be complete, nor an
occupancy permit issued.

            (c) It is expressly understood that all alterations, installations,
or improvements, including wall-to-wall carpet, upon or within the Demised
Premises (whether with or without the Landlord's consent), shall remain upon the
Demised Premises and shall be surrendered with the Demised Premises at the
expiration of the Lease without disturbance, molestation or injury, or, at the
election of the Landlord shall be removed by the Tenant at its cost prior to the
date of lease termination. Should Landlord elect that alterations,
installations, changes, replacements, additions to or improvements made by
Tenant without the Landlord's


                                        7
<PAGE>

consent upon the Demised Premises be removed upon termination of this Lease,
Tenant hereby agrees to cause the same to be removed at Tenant's sole cost and
expense and to restore the Demised Premises to its original condition and should
Tenant fail to remove the same, then and in such event Landlord may cause same
to be removed at Tenant's expense and Tenant hereby agrees to reimburse Landlord
for the cost of such removal together with any and all damages which Landlord
may suffer and sustain by reason of the failure of the Tenant to remove the
same, which cost and damages shall be deemed to be Additional Rent.

            (d) In the event Landlord shall permit the Tenant to make any
alterations, said alterations shall be performed in a good and workmanlike
manner in accordance with all applicable legal requirements.

            (e) If any mechanic's lien is filed against the Demised Premises or
the Property for work or material claimed to have been done for, or furnished
to, Tenant, such mechanic's lien shall be discharged by Tenant within ten (10)
days thereafter, at Tenant's sole cost and expense by payment thereof or posting
such bond or paying such amount as will effect a release of such lien. If Tenant
shall fail to discharge or obtain the release of any such mechanic's lien,
Landlord may, at its option, discharge or release the same and treat the cost
thereof as Additional Rent payable with the monthly installment of Rent next
becoming due; and such discharge or release by Landlord shall not be deemed to
waive the default of Tenant in not discharging or releasing the same. Tenant
shall indemnify and hold Landlord and the holders of any mortgages or deeds of
trust on the Property harmless from and against any and all expenses, liens,
claims or damages to person or property which may or might arise by reason of
the making of any alterations.

      14. Floor Loading. Landlord shall have the right to prescribe the weight,
method of installation and position of heavy fixtures or equipment. Tenant shall
not install in the Demised Premises any fixtures, equipment or machinery that
shall place a load upon any floor exceeding the floor load per square foot area
which said floor was designed to carry. Tenant agrees that all damage done to
the Property by taking in or removing article of Tenant's equipment, or due to
its being in the Demised Premises shall be repaired at the expense of Tenant.
Tenant agrees promptly to remove from the public area any of Tenant's property
there delivered or deposited.

      15. Tenant's Equipment. (a) Tenant shall not install any equipment of any
kind or nature whatsoever which may necessitate any changes, replacements or
additions to, or in the use of the water, heating, air conditioning, plumbing or
electrical systems of the Property, without first obtaining the prior written
consent of Landlord, which may be given or withheld in Landlord's sole and
absolute discretion. Permitted machinery and equipment belonging to Tenant which
cause noise or vibrations that may be transmitted to any part of the Property to
such a degree as to be objectionable to Landlord or to any tenant of the
Property shall be installed and maintained by Tenant, at Tenant's expense, on
vibration eliminators or other devices sufficient to eliminate such noise and
vibrations.

            (b) Maintenance and repair of equipment such as separate air
conditioning equipment or any other type of special equipment, whether installed
by Tenant or by Landlord on behalf of Tenant, shall be the sole responsibility
of Tenant and Landlord shall have no obligation in connection therewith.


                                        8
<PAGE>

      16. Notice of Defects. Tenant shall give Landlord prompt notice of any
defects or breakage in the structure, equipment or fixtures of the Demised
Premises or Property.

      17. Liability. (a) Landlord assumes no liability or responsibility
whatsoever with respect to the conduct and operation of the business to be
conducted in the Demised Premises. Landlord shall not be liable for any accident
or injury to any person or persons or property in or about the Demised Premises
or the Property which are caused by the conduct and operation of said business
or by virtue of equipment or property of Tenant in the Demised Premises. Tenant
agrees to hold Landlord and the holders of any mortgages or deeds of trust on
the Property harmless against all such claims. Tenant shall indemnify and hold
harmless Landlord and the holders of any mortgages or deeds of trust on the
Property from and against any loss, damage or liability occasioned by or
resulting from any default hereunder or any willful or negligent act on the part
of Tenant, its agents, employees or invitee, or persons permitted in the Demised
Premises by Tenant.

            (b) Landlord shall not be liable for any accident or damage caused
by electric light or wires or any accident or damage which may occur through the
operation of heating, air conditioning, lighting or plumbing apparatus, or any
accident or injury occurring in connection with the Property and its services.
All personal property of Tenant in the Demised Premises or on the Property shall
be at the sole risk of Tenant. Landlord shall not be liable for loss or damage
to property of Tenant caused by rain, snow, water or steam that may leak into or
flow from any part of the Property through any defects in the roof or plumbing
or from any other source, including but not limited to acts or omissions on the
part of other tenants of Property or persons using the Property or present
therein. It is understood and agreed that Tenant covenants to save Landlord and
the holders of any mortgages or deed of trust on the Property harmless and
indemnified from all loss, damage, liability or expense incurred by reason of
Tenant's neglect in its use of the Demised Premises or the Property or any part
thereof including the use of the water, steam, electric or other systems, and
the injury, loss or damage to any person or party upon the Demised Premises.

      18. Signs. Tenant agrees that no sign, advertisement or notice shall be
inscribed, painted or affixed on any part of the outside or the inside of the
Demised Premises, or the Property, except adjacent to the doors of the offices,
and then only in such size, color and style as Landlord in its discretion shall
approve. Landlord shall have the right to prohibit any sign, advertisement, or
notice of Tenant which in the Landlord's opinion tends to impair the appearance
or reputation of the Property or its desirability as a building for general
offices, and upon written notice from Landlord Tenant shall refrain from and
discontinue such advertisement and Landlord in addition to its other remedies
for default hereunder, shall have the right to remove the same, and Tenant shall
be liable for any and all costs and expenses incurred by said removal.

      19. Ordinances, Regulations and Rules. (a) Tenant shall at Tenant's cost,
promptly comply with and carry out all orders, requirements or conditions now or
hereafter imposed upon Tenant by the ordinances, laws, and/or regulations of
local, state or federal governments, or by any of their various departments or
agencies, whether required of Landlord or otherwise to be done or performed
during the term of this Agreement, insofar as they are occasioned by or required
in the conduct of the business of Tenant or its occupancy of the Demised
Premises. Tenant shall


                                        9
<PAGE>

indemnify and save Landlord and the holders of any mortgages or deeds of trust
on the Property harmless from all penalties, claims and demands resulting from
failure or negligence in this respect.

            (b) Tenant, its agents, employees and visitors, shall abide by and
observe the rules and regulations set forth below and such other reasonable
rules and regulations as may be promulgated from time to time by Landlord for
the operation and maintenance of the Property provided a copy thereof is sent to
Tenant. Nothing contained in this Lease shall be construed to impose upon
Landlord any duty or obligation to enforce such rules and regulations, or the
terms, conditions or covenants contained in any other lease, as against any
other tenant and Landlord shall not be liable to Tenant for violation of the
same by any other tenant, its employees, agents or invitee.

                  (i) The sidewalks, entries, receiving areas, parking lot and
other parts of the Property which are not occupied by Tenant shall not be

                  (ii) Tenant shall not install or permit the installation of
any exterior awnings, shades, and the like other than those approved by Landlord
in writing.

                  (iii) No additional locks shall be placed upon any doors of
the Demised Premises unless a key to any such lock is first given to the
Landlord.

                  (iv) Tenant shall not construct, maintain, use or operate
within the Demised Premises or elsewhere on the Property any equipment or
machinery which produces music, sound, noise or vibration which is audible or
detectable beyond the Demised Premises.

                  (v) Electric and telephone distribution boxes and air
conditioning equipment must remain accessible at all times.

                  (vi) Tenant shall locate its dumpster or trash container only
next to its loading dock in a manner which does not interfere with other
tenant's use or enjoyment of their space. All dumpsters or trash containers must
be kept closed and must be maintained in a sanitary manner.

                  (vii) No animals of any kind shall be brought into or kept
about the Building by any tenant.

      20. Indemnity. Except in the event of Landlord's primary negligence
directly causing the loss giving rise to the claim, Tenant shall indemnify
Landlord and its agents and employees, the landlord of any underlying lease, and
the holders of any mortgages or deeds of trust on the Property and save them
harmless from and against any and all claims, actions, damages, liabilities and
expense in connection with loss of life, personal injury and/or damage to
property arising from or out of any occurrence in, upon or at the Demised
Premises, or the occupancy or use by Tenant of the Demised Premises or any part
thereof, or occasioned wholly or in part by any act or omission of the Tenant,
its agents, contractors, employees, servants, permitted subtenants, invitee


                                       10
<PAGE>

or licensees, or resulting from any default, breach, violation or
non-performance of this Lease by Tenant. In the event that Landlord or its
agents and employees shall, without fault on their part, be made a party to any
litigation commenced by or against Tenant, then Tenant shall protect and hold
Landlord, the landlord of any underlying lease, and the holders of any mortgages
or deeds of trust on the Property harmless and shall pay all costs, expenses and
reasonable attorney's fees incurred or paid in connection with such litigation.
Tenant shall pay, satisfy and discharge any and all judgments, orders and
decrees which may be recovered against Landlord in connection with the
foregoing.

      21. Entry for Repairs and Inspections. (a) Tenant shall permit Landlord,
or its representatives, to enter the Demised Premises, at all reasonable times,
without diminution of the Rent and Additional Rent payable by Tenant, to
examine, inspect and protect the same, and to make such alterations and/or
repairs as in the judgment of Landlord may be deemed necessary, or to exhibit
the same to prospective tenants, mortgagees or purchasers.

            (b) If Tenant refuses or neglects to repair the Demised Premises as
required hereunder to the reasonable satisfaction of Landlord as soon as is
reasonably possible, Landlord may make such repairs without liability to Tenant
for any loss or damage that may accrue to Tenant's merchandise, fixtures, or
other property or to Tenant's business by reason thereof, and upon completion
thereof, Tenant shall pay Landlord's costs for making such repairs plus twenty
percent (20%) for overhead, upon presentation of a bill therefore, as Additional
Rent.

            (c) Landlord shall at all times have an easement and the right to
enter in and through the Demised Premises for installation and maintenance of
utility connections and facilities reasonably necessary to provide services to
other portions of the Property and the common areas; provided, however, to the
extent reasonably possible the exercise of such rights shall not unreasonably
interfere with the operation of the Tenant's business.

            (d) Landlord's entrance upon the Demised Premises occasioned by this
paragraph shall not constitute an eviction of Tenant in whole or in part and the
Rent and Additional Rent reserved shall in no manner abate while said repairs,
alterations, improvements, or additions are being made, by reason of loss or
interruption of business of Tenant, or otherwise.

      22. Services and Utilities. (a) The Tenant at its cost shall provide for
its own use the following:

                  (i) all utilities in and for the Demised Premises, including
without limitation, electric, gas, sewer, water, telephone and cable utility
services;

                  (ii) all janitorial, cleaning and char services;

                  (iii) all servicing, maintenance, repair and replacement of
electric lighting, electric service, plumbing, plumbing fixtures, supplemental
heating, ventilating and air conditioning equipment, and other mechanical and
electrical equipment within the Demised Premises, including tenant improvements
and fixtures;


                                       11
<PAGE>

                  (iv) servicing, maintenance and repair of the base building
heating, ventilating and air conditioning equipment by a qualified service
contractor; and

                  (v) trash removal service from such dumpster location or
locations on the grounds of the Property as Landlord may designate.

            (b) Provided that the Tenant is not in default under any provision
of this Lease, the Tenant has not been negligent in its use of any heating,
ventilating and air conditioning equipment, and Tenant has periodically
maintained such equipment as required herein, under a service contract with a
qualified service contractor, Landlord shall replace or rebuild any such
equipment which, as a result of normal usage and depreciation, fails to function
despite Tenant's maintenance and repair;

            (c) Any failure by Landlord to furnish the foregoing services shall
not render Landlord liable in any respect for damages to either person or
property, nor be construed as an eviction to Tenant, nor work an abatement of
Rent, nor relieve Tenant from Tenant's obligations hereunder.

      23. Insurance. (a) Tenant shall not conduct or permit to be conducted any
activity or place any equipment in or about the Demised Premises which will, in
any way, increase the rate of insurance premiums on the Property. If any
increase in the rate of insurance premiums is stated by any insurance company or
by the applicable Insurance Rating Bureau to be due to any activity or equipment
in or about the Demised Premises, such statement shall be conclusive evidence
that the increase in such rate is due to such activity or equipment and, as a
result thereof, Tenant shall be liable for such increase and shall reimburse
Landlord therefor, within ten (10) days of receipt of written notice, said sum
shall be deemed to be Additional Rent.

            (b) Landlord shall insure the building, of which the Demised
Premises are a part, against damage by fire, including extended coverage, in any
amount Landlord in its sole discretion shall deem adequate, and shall maintain
such insurance throughout the term hereby demised. Tenant shall insure all of
its property in the Demised Premises against damage by fire, including extended
coverage, in an amount as shall be determined by the Landlord in consultation
with Tenant, and Tenant shall maintain such insurance throughout the term hereby
demised. In addition, Tenant shall also maintain with respect to the Demised
Premises, comprehensive public liability insurance, with minimum limits of
$500,000/$1,000,000 per personal injury, and $100,000 for property damage.
Tenant shall maintain the insurance coverage required herein with a company or
companies acceptable to Landlord, insuring the Landlord and its managing agent
as additional named insured, as well as Tenant, against bodily injury to or
death of persons, and against property damage as herein provided. Tenant shall
deliver certificates of insurance indicating the above specified coverage to the
Landlord upon the commencement of the Term of this Lease, and continuing
evidence of such coverage annually or upon request. Such insurance policy or
policies shall be reasonably satisfactory to Landlord and shall provide that it
(they) cannot be canceled without at least thirty (30) days prior written notice
to the Landlord. Tenant agrees to cause a waiver of subrogation to be included
in its policies of fire and extended


                                       12
<PAGE>

coverage insurance, if obtainable from its insurers. In the event Tenant shall
fail to maintain the public liability insurance coverage required by this
paragraph, Landlord may, at its option, pay the same and treat the cost of the
premiums as Additional Rent payable with the monthly installment of Rent next
becoming due.

      24. Damage by Fire or Other Casualty. If the Property shall be partially
damaged by fire or other cause, other than the failure or neglect of Tenant,
Landlord shall as soon as practicable after such damage occurs (taking into
account the time necessary to effectuate a satisfactory settlement with any
insurance company) repair such damage at the expense of Landlord, and the Rent
shall be reduced in proportion to the extent the Demised Premises are rendered
untenantable until such repairs are completed; provided, however, that if the
Property is substantially damaged by fire or other cause to such extent that the
damage cannot be fully repaired within sixty (60) days from the date of such
damage, and if such loss was not caused by the Tenant's failure or neglect,
Landlord or Tenant shall have the option of terminating this Lease by giving
written notice to the other party of such decision and the term of this Lease
shall terminate ten (10) days after such notice is given. No compensation or
reduction of Rent shall be allowed or paid by Landlord by reason of
inconvenience, annoyance, or injury to business arising from the necessity of
repairing the Demised Premises or any portion of the Property.

      25. Eminent Domain. If the whole or a substantial part of the Demised
Premises shall be taken or condemned by governmental authority for any public or
quasi-public use or purpose, then the term of this Lease shall cease and
terminate as of the date when title vests in such governmental authority, and
Tenant shall not have any claim against Landlord and shall not have any claim
for any portion of the amount that may be awarded as damages as a result of such
taking or condemnation or for the value of any unexpired term of the Lease;
provided, however, that Tenant may separately assert any claim that it may have
against the condemning authority for compensation for any fixtures owned by
Tenant and for any relocation expenses compensable by statute. If less than a
substantial part of the Demised Premises is taken or condemned by any
governmental authority for any public or quasi-public use or purpose, the Rent
shall be equitably adjusted on the date when title vests in such governmental
authority and the Lease shall otherwise continue in full force and effect. For
purposes hereof, a substantial part of the Demised Premises shall be considered
to have been taken if more than twenty percent (20%) of the Demised Premises are
unusable by Tenant.

      26. Defaults and Remedies. (a) The following events shall be a default
(hereinafter referred to as a "Default") of Tenant under this Lease:

                  (i) Failure of Tenant to make any payment of Rent (including
Annual Increase) when due.

                  (ii) Failure of Tenant to make any payment of Additional Rent
when due.

                  (iii) Failure of Tenant to perform or comply with any
provision of this Lease to be performed or complied with by Tenant, other than
provisions for the payment of Rent


                                       13
<PAGE>

or Additional Rent, where such failure shall continue for a period of ten (10)
days after written notice thereof by Landlord to Tenant.

                  (iv) The taking of this Lease or the Demised Premises, or any
part thereof, upon execution or by other process of law directed against Tenant,
or upon or subject to any attachment at the instance of any creditor of or
claimant against Tenant, which execution or attachment shall not be discharged
or disposed of within thirty (30) days after the levy thereof.

                  (v) If Tenant fails to take possession of the Demised Premises
within a reasonable period of time after the lease commencement of the Term of
this Lease or substantially vacates or abandons the Demised Premises prior to
the normal expiration of the term.

                  (vi) The circumstance of Tenant, or any guarantor of Tenant's
obligation hereunder, in financial difficulties as evidenced by (1) its
admitting in writing its inability to pay its debts generally as they become
due, or (2) its filing a petition in bankruptcy or for reorganization or the
adoption of an arrangement under the Bankruptcy Act (as now or hereafter
existing), or an answer or other pleading admitting the material allegations of
such a petition or seeking, consenting to or acquiescing in the relief provided
for under such Act, or (3) its making an assignment of all or a substantial part
of its property for the benefit of its creditors or (4) its seeking or
consenting to or acquiescing in the appointment of a receiver or trustee for all
or a substantial part of its property or of the Demised Premises, or (5) its
being adjudicated a bankrupt or insolvent, or (6) the entry of a court order
without its consent, which order shall not be vacated, set aside or stayed
within sixty (60) days from the date of entry, appointing a receiver or trustee
for all or a substantial part of its property or approving a petition filed
against it for the effecting of an arrangement in bankruptcy or for a
reorganization pursuant to the Bankruptcy Act or for any other judicial
modification or alteration of the rights of creditors.

            (b) The provisions of this paragraph shall apply notwithstanding the
payment by Tenant of the security deposit and/or the continued willingness and
ability of Tenant to pay Rent and otherwise perform hereunder. The receipt by
Landlord of payments of Rent, as such, accruing subsequent to the time of
Tenant's default under this paragraph and even though Landlord may have actual
notice of the occurrence of an event of Default under this paragraph shall not
be deemed a waiver by Landlord of the provisions of this paragraph.

            (c) Upon the occurrence of a Default, Landlord shall have the right
at its election, then or at any time thereafter either:

                  (i) To give Tenant written notice of Landlord's intent to
terminate this Lease on the date of the notice or on any later date, specified
in the notice, and on such date Tenant's right to possession of the Demised
Premises shall cease and this Lease shall thereupon be terminated; or

                  (ii) to re-enter without demand or notice and to take
possession of all or any part of the Demised Premises and expel Tenant and those
claiming through Tenant, and remove the property of Tenant and any other person,
either by summary proceedings, by action at


                                       14
<PAGE>

law or in equity, by force without due process of law, or by any other means,
without being deemed guilty of trespass or liable for prosecution or damages
therefor, and without prejudice to any remedies for nonpayment or late payment
of Rent or breach of covenant. If Landlord elects to reenter under this
provision, Landlord may terminate this Lease, or, from time to time, without
terminating this Lease, may relet all or any part of the Demised Premises as
agent for Tenant for such term or terms and at such rental and upon such other
terms and conditions as Landlord may deem advisable in its sole and absolute
discretion, with the right to make alterations and repairs to the Demised
Premises. No such reentry or taking of possession of the Demised Premises by
Landlord shall be construed as an election on Landlord's part to terminate this
Lease unless a written notice of such intention is given to Tenant or unless the
termination be decreed by a court of competent jurisdiction at the instance of
Landlord. Nothing herein shall be construed to require the Landlord to mitigate
damages.

            (d) If Landlord terminates this Lease pursuant to the preceding
subparagraph, Tenant shall remain liable (in addition to accrued liabilities)
for (i) Rent, Additional Rent and any other sums provided for in this Lease
until the date this Lease would have expired had such termination not occurred,
and any and all expenses (including attorney's fees, disbursements and brokerage
fees) incurred by Landlord in reentering and repossessing the Demised Premises,
in making good any Default of Tenant, in painting, altering, repairing or
dividing the Demised Premises, in protecting and preserving the Demised Premises
by use of watchmen and caretakers, and in reletting the Demised Premises, and
any and all expenses which Landlord may incur during the occupancy of any new
tenant; less (ii) the net proceeds of any reletting prior to the date this Lease
would have expired if it had not been terminated. Tenant agrees to pay to
Landlord the difference between items (i) and (ii) above for each month during
the Term, at the end of each such month. Any suit brought by Landlord to enforce
collection of such difference for any one month shall not prejudice Landlord's
right to enforce the collection of any difference for any subsequent month. In
addition to the foregoing, and without regard to whether this Lease has been
terminated, Tenant shall pay to Landlord all costs incurred by Landlord,
including reasonable attorney's fees, with respect to any lawsuit or action
instituted or taken by Landlord to enforce the provisions of this Lease.
Tenant's liability shall survive the institution of summary proceedings and the
issuance of any writ of restitution thereunder.

            (e) If Landlord terminates this Lease, Landlord shall have the
right, at any time, at its option, to require Tenant to pay to Landlord on
demand, as liquidated and agreed final damages in lieu of Tenant's liability
hereunder, the Rent, Additional Rent and all other charges which would have been
payable from the date of such demand to the date when this Lease would have
expired if it had not been terminated, (minus the fair rental value negotiated
in good faith with another tenant of the Demised Premises for the same period,
if any). If the Demised Premises shall have been relet for all or part of the
remaining balance of the Term by Landlord after a Default but before
presentation of proof of such liquidated damages, the amount of rent reserved
upon such reletting shall be deemed the fair rental value of the Demised
Premises for purposes of the foregoing determination of liquidated damages. Upon
payment of such liquidated and agreed final damages, Tenant shall be released
from all further liability under this Lease with respect to the period after the
date of demand.


                                       15
<PAGE>

            (f) Tenant, on its own behalf and on behalf of all persons claiming
through Tenant, including all creditors does hereby waive any and all rights and
privileges, so far as is permitted by law, which Tenant and all such persons
might otherwise have under any present or future law (i) to the service of any
notice of intention to reenter which may otherwise be required to be given, (ii)
to redeem the Demised Premises, (iii) to reenter or repossess the Demised
Premises, or (iv) to restore the operation of this Lease, with respect to any
dispossession of Tenant by judgment or warrant of any court or otherwise,
whether such dispossession, reentry, expiration or termination be by operation
of law or pursuant to the provisions of this Lease.

            (g) In the event of any breach by Tenant or any person or persons
claiming through Tenant of any of the provisions contained in this Lease,
Landlord shall be entitled to enjoin such breach and shall have the right to
invoke any right or remedy allowed at law or otherwise as if reentry, summary
proceedings or other specific remedies were not provided for in this Lease.

            (h) Landlord shall, to the extent permitted by law, have (in
addition to all other rights) a right of distress for Rent and Additional Rent
and a lien on all Tenant's personal property as security for all adjusted Rent,
Additional Rent and any other sums payable under this Lease.

            (i) If Tenant defaults in the making of any payment to a third party
or in the doing of any act herein required to be made or done by Tenant, then
after ten (10) days notice from Landlord (except in the event of nonpayment of
Rent or Additional Rent, for which no notice is required), Landlord may, but
shall not be required to, make such payment or do such act, and the amount and
the expense thereof, if made or done by Landlord, with interest thereon at the
rate of three hundred (300) base points over the prime rate of Crestar Bank,
Richmond, Virginia, or its successor, but not to exceed the highest lawful rate,
from the date paid by Landlord, shall be paid by Tenant to Landlord and shall
constitute Additional Rent hereunder due and payable with the next monthly
installment of Rent; but the making of such payment or the doing of such act by
Landlord shall not operate to cure such Default or to estop Landlord from the
pursuit of any remedy to which Landlord would otherwise be entitled.

            (j) All rights and remedies of Landlord under this Lease shall be
cumulative and shall not be exclusive of any other rights and remedies provided
to Landlord now or hereafter under law or under this Lease.

      27. Waiver. If under the provisions hereof Landlord shall institute
proceedings and a compromise or settlement thereof shall be made, the same shall
not constitute a waiver of any covenant herein contained nor of any of
Landlord's rights hereunder. No waiver by Landlord of any breach of any
covenant, condition or agreement herein contained shall operate as a waiver of
such covenant, condition or agreement itself, or of any subsequent breach
thereof. No payment by Tenant or receipt by Landlord of a lesser amount than the
monthly installments of Rent herein stipulated shall be deemed to be other than
on account of the earliest stipulated Rent, nor shall any endorsement or
statement on any check or letter accompanying a check for payment of Rent or
Additional Rent be deemed an accord and satisfaction, and Landlord may accept
such check or payment without prejudice to Landlord's right to recover the
balance of such Rent or Additional


                                       16

Rent or to pursue any other remedy provided in this Lease. No reentry by
Landlord, and no acceptance by Landlord of keys from Tenant, shall be considered
an acceptance of a surrender of this Lease.

      28. Subordination. This Lease is subject and subordinate to all ground or
underlying leases and to all mortgages and/or deeds of trust which may now or
hereafter affect such leases or the Property and to all renewals, modifications,
consolidations, replacements and extensions thereof. This clause shall be
self-operative and no further instrument of subordination shall be required by
any mortgagee or trustee. In confirmation of such subordination, Tenant shall
execute promptly any certificate that the Landlord may request. Tenant hereby
constitutes and appoints Landlord the Tenant's attorney-in-fact to execute any
such certificate or certificates for an on behalf of Tenant. Notwithstanding the
foregoing, the party secured by any such deed of trust shall have the right to
recognize this Lease and, in the event of any foreclosure sale under such deed
of trust, or deed in lieu thereof, this Lease shall continue in full force and
effect at the option of the party secured by such deed of trust or the purchaser
under any such foreclosure sale; Tenant covenants and agrees that it shall at
the written request of the party secured by any such deed of trust, execute,
acknowledge and deliver any instrument that has for its purpose and effect the
subordination of this Lease to the lien of said deed of trust and the attornment
of the Tenant to such party. At the option of any landlord under any ground or
underlying lease to which this Lease is now or may hereafter become subject or
subordinate, Tenant agrees that neither the cancellation nor termination of such
ground or underlying lease shall by operation of law or otherwise, result in
cancellation or termination of this Lease or the obligations of the Tenant
hereunder, and Tenant covenants and agrees to attorn to such landlord or to any
successor to Landlord's interest in such ground or underlying lease and in that
event, this Lease shall continue as a direct lease between Tenant herein and
such landlord or its successor; and, in any case, such landlord or successor
under such ground or underlying lease shall not be bound by any prepayment on
the part of Tenant of any Rent for more than one month in advance, so that Rent
shall be payable under this Lease in accordance with its terms, from the date of
the termination of the ground or underlying lease, as if such prepayment had not
been made. Such landlord or successor under such ground or underlying lease
shall not be bound by this Lease or any amendment or modification of this Lease
unless, prior to the termination of such ground or underlying lease, a copy of
this Lease or amendment or modification thereof, as the case may be, shall have
been delivered to such landlord or successor.

      29. Estoppel Certificates. Tenant agrees, at any time and from time to
time, upon not less than five (5) days prior notice by Landlord, to execute,
acknowledge and deliver to Landlord a statement in writing in such form as
Landlord may request, (i) certifying that this Lease is unmodified (or if
modified, stating the modifications) and in full force and effect (or if not in
full force and effect, the reasons therefor), (ii) stating the dates to which
the Rent, Additional Rent and other charges hereunder have been paid by Tenant,
(iii) stating whether or not to the best knowledge of Tenant, Landlord is in
default in the performance of any covenant, agreement or condition contained in
this Lease, and if so, specifying each such default of which Tenant may have
knowledge, and (iv) stating the address to which notices to Tenant should be
sent. Any such statement delivered pursuant hereto may be relied upon by any
owner of the Property, any prospective purchaser of the Property, any mortgagee
or prospective mortgagee of the Property,


                                       17
<PAGE>

any prospective assignee of any such mortgagee, or any lessor or prospective
lessor of the land which is a part of the Property.

      30. No Recourse to Landlord. The obligations of Landlord under this Lease
do not constitute personal obligations of the individual partners, directors,
officers, or shareholders of Landlord, and Tenant shall look solely to the
Property of which the Demised Premises are a part and to no other assets of the
Landlord or the holders of any mortgages or deeds of trust on the Property for
satisfaction of any liability in respect of this Lease and shall not seek
recourse against the individual partners, directors, officers or shareholders of
Landlord or the holders of any mortgages or deeds of trust on the Property or
any of their personal assets for such satisfaction.

      31. Holding Over. If Tenant shall, with the knowledge and consent of
Landlord, continue to remain in the Demised Premises after the expiration of the
Term of this Lease and any extensions thereof, then and in such event, Tenant
shall, by virtue of this agreement become a tenant by the month at a monthly
rental equal to one hundred twenty percent (120%) of the monthly installment of
Rent agreed by the Tenant to be paid as aforesaid, commencing said monthly
tenancy with the first day next after the end of the Term above demised. Tenant
shall give to Landlord at least thirty (30) days written notice of any intention
to quit the Demised Premises, and Tenant shall be entitled to thirty (30) days
written notice to quit the Demised Premises, except in the event of non-payment
of Rent or Additional Rent or of the breach of any other covenant by Tenant, in
which event Tenant shall not be entitled to any notice to quit, the usual thirty
(30) days notice to quit being hereby expressly waived; provided, however, that
in the event that Tenant shall hold over after the expiration of the Term hereby
created, and if Landlord shall desire to regain possession of the Demised
Premises promptly at the expiration of the Term aforesaid, then at any time
prior to Landlord's acceptance of Rent from Tenant as a monthly tenant
hereunder, Landlord, at it option, may forthwith reenter and take possession of
the Demised Premises without process, or by any legal process in force.

      32.Submission of Lease. The submission of this Lease for examination by
Tenant does not constitute a reservation of or option for the Demised Premises,
and this Lease shall become effective as a lease only upon execution and
delivery thereof by Landlord and Tenant.

      33. Covenant of Landlord. Landlord covenants that it has the right to make
this Lease, and that if Tenant shall pay the Rent and Additional Rent and shall
perform all of Tenant's obligation under this Lease, Tenant shall, during the
term hereof, freely, peaceably and quietly occupy and enjoy the full possession
of the Demised Premises without molestation or hindrance by Landlord or any
party claiming through or under Landlord, subject, however, to the underlying
lease, mortgages and deeds of trust described in Paragraph 28 and except as
otherwise provided herein. The term "Landlord" as used herein shall mean solely
the owner of Landlord's interest in the Property, whoever that may be at the
relevant time, so that in the event of any sale or transfer of Landlord's
interest in the Property, any prior Landlord shall be freed and relieved of all
covenants and obligations of Landlord hereunder.

      34. Force Majeure. If Landlord, as the result of any (i) strikes,
lockouts, or labor disputes; (ii) inability to obtain labor, materials, fuel,
electricity, services or reasonable substitutes


                                       18
<PAGE>

therefore; (iii) acts of God, civil commotion, fire or other casualty; (iv)
governmental action of any kind; or (v) other conditions similar to those
enumerated above beyond Landlord's reasonable control, fails punctually to
provide any service or to perform any obligation on its part to be performed
hereunder, then, unless otherwise expressly provided, such failure shall be
excused and shall not be a breach hereunder, but only to the extent occasioned
by such event. In the event, however, that any such event shall prevent
Landlord's performance for a period longer than sixty (60) consecutive days, the
Tenant shall have the right to terminate this Lease.

      35. Omitted.

      36. Omitted.

      37. Waiver of Trial by Jury. Tenant hereby waives all right to trial by
jury in any claim, action, proceeding or counterclaim by either Landlord or
Tenant against each other on any matters arising out of or in any way connected
with this Lease, the relationship of Landlord and Tenant, and/or Tenant's use or
occupancy of the Demised Premises.

      38. Attorney's Fees. If, in the event of a default by Tenant, Landlord
places the enforcement of this Lease, or any part thereof, or the collection of
any Rent or Additional Rent due, or to become due hereunder, or recovery of the
possession of the Demised Premises in the hands of an attorney, or files suit
upon the same, Tenant agrees to pay Landlord's attorney's fees.

      39. Brokers. Landlord and Tenant each represent and warrant that neither
of them has employed any broker in carrying on the negotiations relating to this
Lease. Landlord shall indemnify and hold Tenant harmless, and Tenant shall
indemnify and hold Landlord harmless, from and against any claim for brokerage
or other commission arising from or out of any breach of the foregoing
representation and warranty.

      40. Notices. All notices or other communications hereunder shall be in
writing and shall be deemed duly given if delivered in person or sent by
certified or registered mail, return receipt requested, first class, postage
prepaid, (i) if to Landlord, at Suite 200, 1201 E. Abingdon Drive, Alexandria,
Virginia 22314, and (ii) if to Tenant at 500 Pendleton Street, Alexandria,
Virginia 22314, unless notice of a change of address is given pursuant to the
provisions of this paragraph.

      41. Miscellaneous. (a) This Lease and the Exhibits attached hereto contain
and embody the entire agreement of the parties hereto and no representations,
inducements, or agreements, oral or otherwise, between Landlord and Landlord's
agents and Tenant not contained in this Lease and Exhibits shall be of any force
or effect. This Lease may not be modified, changed or terminated in whole or in
part in any manner other than by an agreement in writing duly signed by both
parties hereto.

            (b) The terms, covenants and conditions hereof shall be binding upon
and inure to the permitted successors in interest and assigns of the parties
hereto. Landlord may freely and idly assign its interest hereunder.


                                       19
<PAGE>

            (c) If any provision of this Lease or the application thereof to any
person or circumstances shall to any extent be held void, unenforceable or
invalid, then the remainder of this Lease or the application of such provision
to persons or circumstances other than those as to which it is held void,
unenforceable or invalid shall not be affected thereby, and each provision of
this Lease shall be valid and enforceable to the fullest extent permitted by
law.

            (d) Tenant shall not record this Lease without the written consent
of Landlord, which may be given or denied in Landlord's sole discretion. If
Landlord consents to such recordation, the cost thereof shall be paid by Tenant.

            (e) The captions and headings throughout this Lease are for
convenience and reference only and the words contained therein shall in no way
be held or deemed to define, limit, describe, explain, modify, amplify or add to
the interpretation, construction or meaning of any provision of or the scope of
intent of this Lease nor in any way affect this Lease.

            (f) Nothing contained in this Lease shall be deemed or construed to

create any other relationship between the parties hereto other than that of
Landlord and Tenant.

            (g) Feminine or neuter pronouns shall be substituted for those of
the masculine form, the plural shall be substituted for singular number and vice
versa in any place or places herein in which the context may require such
substitute or substitution.

            (h) This Lease is to be construed under the laws of the jurisdiction
in which the Property is located.

      42. Omitted.

      43. Authority of Landlord and Tenant. Each individual executing this Lease
on behalf of Landlord and Tenant represents and warrants that he is duly
authorized to execute and deliver this Lease on behalf of Landlord or Tenant in
accordance with a partnership agreement or a duly adopted resolution of the
Board of Directors or in accordance with its bylaws and that this Lease is
binding upon Landlord and Tenant in accordance with its terms.
