                                     PART I

Item 1. DESCRIPTION OF BUSINESS

      Sonics & Materials, Inc. (the "Company" or "Sonics") designs, manufactures
and sells (i) ultrasonic bonding equipment for the welding, joining and
fastening of thermoplastic components, textiles and other synthetic materials,
and (ii) ultrasonic liquid processors for dispersing, blending, cleaning,
degassing, atomizing and reducing particles as well as expediting chemical
reactions. To further address the needs of its customers, the Company also
manufactures a spin welder and the vibration welder, both of which are used for
the bonding of thermoplastic components.

      The Company was incorporated in New Jersey in April 1969, and was
reincorporated in Delaware in October 1978. Robert S. Soloff, its chairman,
president and founder, invented the ultrasonic plastic welding process early in
his career. He has been granted nine patents in the field of power ultrasonics
and is considered to be a pioneer in the application of ultrasonic technology to
industrial processes. Howard Deans, general manager of the Company's Ultra Sonic
Seal division, has also invented ultrasonic devices and processes covered by
patents primarily for packaging and sealing. The patents granted to Messrs.
Soloff and Deans have expired and the technology related to them is now in the
public domain and is used in part in the development and manufacture of the
Company's products.

      On July 25, 1997, the Company acquired Tooltex, Inc., an Ohio corporation
("Tooltex"), through a merger transaction (the "Merger"). Tooltex is a
manufacturer of automated systems used in the plastics industry. Pursuant to an
Agreement and Plan of Merger, dated July 25, 1997 (the "Plan of Merger"), among
Sonics,(SM) Sub, Inc., an Ohio corporation and a wholly owned subsidiary of
Sonics ("Sonics Sub"), Tooltex, and the shareholders of Tooltex, Tooltex was
merged with and into Sonics Sub. Sonics Sub then changed its name to Tooltex,
Inc. (the "Surviving Corporation"). Under the Plan of Merger the shareholders of
Tooltex received, in exchange for 100% of the stock of Tooltex, (i) an aggregate
of 70,000 shares of Sonics Common Stock, par value $.03 per share (the "Common
Stock"), (ii) $70,000 and (iii) options to purchase 10,000 shares of Sonics
Common Stock. The former shareholders of Tooltex have surrendered the 70,000
shares of Sonics Common Stock to the Company in satisfaction of certain
indemnification obligations provided in the Plan of Merger.

      In September of 1997, the Company also formed a wholly owned subsidiary,
Vibra-Surge Corporation, for the manufacture and sale of its ultrasonic surgical
device. See "Products" below.

Products

      The Company manufactures equipment in the following categories:

      Ultrasonic Welders -- Manufactured by the Company since its founding, this
line of ultrasonic devices welds, bonds, fastens, sews and rivets thermoplastic
components and other synthetic materials. As new applications were requested by
industrial customers, the line has expanded over the years. Plastic welders and
related devices are used in a wide variety of industries and applications. These
include the automotive, computer, electronics, packaging, toy, home
entertainment, medical device, textile and garment, and home appliance
industries.

      There are certain advantages to ultrasonic bonding in comparison to more
traditional welding techniques. Uniform production is often accomplished due to
the consistency, speed and focusing of the energy applied to the welded part.
The bond created between the components is generally strong and clean. Because
no solvents, adhesives or external heat are involved, adverse environmental
factors are minimized. Materials which may not be easily assembled or welded by
other technologies can be effectively bonded ultrasonically. Moreover,
ultrasonic bonding is generally faster and requires less skilled labor or
training than many other methods.


          1
<PAGE>

      Liquid Processors - Liquid processors, which are sold under the Company's
trade name "Vibra-Cell" or under private label, are ultrasonic devices that
disperse, break up, emulsify, atomize, mix and blend substances in a liquid or
semi-liquid media. Substances affected by liquid processing include molecules,
cells, tissues, fluids, chemicals and particles. These devices are available in
different power configurations for low, medium and high volume applications with
various capacities, features and accessories. Operating similarly to ultrasonic
bonding systems and composed of many of the same components, liquid processors
produce a different result because they are utilized in liquid, semi-liquid and
powdered media.

      Liquid processors are utilized in biotechnology by scientists, biologists,
chemists and pharmacologists, primarily in laboratories for research and testing
purposes. The Company has extended the applications for its liquid processors
from the research laboratories to industrial settings. The liquid processor also
functions to process and test materials and substances on the production line
and in vats and tanks. In the manufacture of pharmaceuticals and in the
processing of petroleum products and certain specialty chemicals, they reduce
particle size and facilitate mixing; in the preparation of paint and dyes, they
blend and homogenize materials. In the ink industry, processors disperse black
carbon. In the beverage and other industries, they are used to de-gas carbonated
soda, wine, beer, spirits and solvents. The Company's liquid processors are also
used as high-intensity cleaners. These ultrasonic cleaning devices are effective
in spot cleaning and removing various contaminants, such as radioactive
particles, proteins, rust, blood, and oil from laboratory equipment.

      The Company also manufactures a liquid processor with a spray nozzle that
atomizes fluids by producing ultra-fine sprays in precisely measured dosages or
at extremely low flow rates. Utilized in laboratories and plants, ultrasonic
atomizers can coat, moisten, or deposit micro-droplets of liquid on glass,
fabric, paper, semiconductors, pharmaceuticals, ceramics or tubes. They are also
used to apply silicone and Teflon, disinfect surfaces and lubricate small parts.

      Vibration Welder -- Vibration welders are generally used to weld larger
plastic components together, and have the ability to weld a wider variety of
plastics. In this technology, a non-vibrating part is hydraulically lifted from
below to meet a horizontally-vibrating part. The vibrations cause friction and
heat, melting the plastic, and a bond is effectuated between the plastic parts.
The vibration welder that has been designed and is currently being manufactured
by the Company is computer-controlled and has a power supply, digital display
and other features similar to the Company's ultrasonic welder.

      Spin Welder -- The Company has developed and currently manufactures spin
welders based on a non-ultrasonic process known as rotary friction welding.
Rotary friction welding is a bonding technology generally used only when
assembling cylindrical or round-shaped thermoplastic parts. It is also better
suited for plastics of a semi-crystalline nature and assemblies requiring
significant tooling relief. In spin welding, one plastic component is spun
against a mating plastic part that is held stationary in a nesting fixture.
Friction generated by the spinning action produces heat which melts the plastic
and fuses the two parts together.

      The spin welding system offered by Sonics features, among other things, a
multi-function programmable controller, RPM display, and a two horsepower
electronic drive motor that spins the plastic part. The spin welder is composed
of a steel frame and column with a control box. Other components of the system
include a pneumatic head, an automotive spindle bearing, an air brake and clutch
system, and steel plates.

      Ultrasonic Surgical Instrument -- The Company has designed and developed
an ultrasonic medical device, the Vibra-Surge(TM) System Model VS 2120
("Vibra-Surge"), for the removal of soft tissue in general and reconstructive
and plastic surgery. Sonics filed a patent application and a preliminary patent
application covering Vibra-Surge(TM) with the U.S. Patent and Trademark Office
on May 1, 1997. The preliminary patent application has been abandoned. It is not
certain whether a patent for the remaining application will be issued or, if
issued, that such patents will offer adequate protection or will not be
challenged by the holders of prior or other patents issued or to be issued for
similar purposes. The device received 510(k) clearance from the Food and Drug
Administration (the "FDA") on July 25, 1997 which permits Sonics to market the
device. In September 1997, Sonics created a wholly owned subsidiary, Vibra-Surge
Corporation, which signed an exclusive distribution agreement with Sonimedix,
Inc. ("Sonimedix") on September, 19, 1997. Under the distribution agreement,
Sonimedix serves as the exclusive worldwide distributor of Vibra-Surge(TM). On
September 25,


          2
<PAGE>

1997, Sonics transferred to Vibra-Surge Corporation all of its rights and
obligations under the 510(k) FDA clearance and patent applications and all of
the technology related to Vibra-Surge(TM).

      Industry Background

      Management believes that in recent years the market for ultrasonic bonding
systems, and other plastic assembly systems has undergone steady and consistent
growth. It appears that more companies are seeking to replace metal components
with thermoplastics in order to reduce the weight of products or to capitalize
on other special properties of synthetic substances. Consequently, ultrasonic
bonding systems and related welding devices have been more extensively utilized
in industrial processing and in new assembly applications. In contrast,
management believes that the market for liquid processors in the past has
experienced inconsistent growth and occasional contractions. To a certain
extent, the past decline in sales of liquid processors in the research
laboratory area has been offset by new and more extensive applications of such
technology in other industries, such as the paint, chemical, petroleum and
beverage industries, and medical industries. The market for liquid processors
has only recently stabilized and appears to have resumed its growth. Ultrasonic
food processing systems were introduced to the market place approximately three
years ago. Sonics believes that while the market for these systems is relatively
young, the market will expand as ultrasonics cutters are accepted as an
alternative to conventional or waterjet cutters.

Manufacturing and Supply

      Sonics' manufacturing operations, conducted at its facilities located in
Danbury, Connecticut, Aston, Pennsylvania, and Grove City, Ohio, are run on a
batch basis in which a series of products move irregularly from station to
station. The Company manufactures its products pursuant to historical and
projected sales data as well as specific customer orders.

      Most supplies and materials required in the manufacture of the Company's
products are available from many sources. Many of its suppliers are based in the
same general locality as the Company's manufacturing operations. To date, Sonics
has experienced few shortages and delays regarding supplies and materials.
However, it is not certain that such shortages or delays may not have an adverse
impact on Sonics' operations in the future. No one supplier accounted for more
than 5% of its total purchases for inventory made in fiscal years 1997 or 1998.
Although management believes that in all cases alternate sources of supplies can
be located, a certain amount of time would inevitably be required to find
substitutes. During any such interruption in supplies, the Company may have to
curtail the production and sale of its devices and systems for an indefinite
period.

      Sonics is not a party to any formal written contract regarding the
delivery of its supplies and materials. It generally purchases such items
pursuant to written purchase orders of both the individual and blanket
varieties. Blanket purchase orders usually entail the purchase of larger amounts
of items at fixed prices for delivery and payment on specific dates ranging from
two months to one year.

      Sonics has qualified its Connecticut facility to meet the quality
management and assurance standards of an international rating organization (ISO
9001). ISO 9001 certification indicates that the Company has successfully
implemented a quality assurance system that satisfies this standard. Sonics has
also obtained CE approvals, which are now necessary for sales in Europe, for
many models of its ultrasonic welder and liquid processor. It is working towards
CE approvals for its other product lines.

Maintenance and Service

      The Company offers warranties on all its products, including parts and
labor, that range from one year to three years depending upon the type of
product concerned. For the fiscal years ended June 30, 1997 and 1998, expenses
attributable to warranties were approximately $77,000 and $66,000, respectively.
Sonics performs repair services on all of its products sold domestically either
at its Connecticut or Pennsylvania facilities or at customer locations.
Servicing of foreign sales is usually handled by distributors abroad or in the
Company's Swiss branch office regarding its devices sold in


          3
<PAGE>

Europe. These services are performed upon specific orders without contracts at
various rates. The Company usually charges for the time that its employees
expend on the task and the cost of the materials or parts involved in the
repair. For the fiscal years ended June 30, 1997 and 1998, the Company had
income of approximately $398,000 and $446,000, respectively, for out-of-warranty
services performed. Company devices generally have a long operating life, and
Sonics has repaired machines manufactured by it that are more than 28 years old.

Sales and Marketing

      Sonics generally markets and sells its products in the United States and
abroad through a network of sales representatives and distributors to end users
and original equipment manufacturers ("OEMs"). In the United States, the Company
and its Ultra Sonic Seal division ("USS") utilize approximately 50 sales
representatives in 48 states throughout the country. The Company's wholly owned
subsidiary, Tooltex, utilizes two sales representatives throughout the Midwest.
In the overseas market, it relies on approximately 66 distributors and several
sales representatives to distribute its products in 49 countries. The areas
covered by these third parties include North and South America, the Middle and
Far East, Europe and Australia.

Sales Representatives

      The Company's relationship with its sales representatives is usually
governed by a written contract which is generally terminable by either party on
30 days prior notice. The contract provides for exclusive territorial and
product representation and commissions payable to them on their sales depending
on whether basic units or accessories are involved and typically covers
ultrasonic bonding systems and liquid processors. OEM sales made by the Company
are excluded from the commission arrangements. Generally, the sales
representatives do not purchase for their own account, but merely sell Sonics'
products on the Company's behalf. They also may represent other manufacturers
but generally not those competitive with the Company's products. No one sales
representative accounted for more than 5% of Sonics' sales in either fiscal year
1997 or 1998. The loss of such representatives representing in the aggregate
significant sales may have a material adverse impact on the Company's business.

      USS sells its plastic welder under its division name. USS maintains a
network of sales representatives in the United States different from those for
Sonics' main product lines. The terms of these arrangements with its sales
representatives are similar to the terms Sonics negotiates with its own sales
representatives.

      The Company's wholly owned subsidiary, Tooltex, sells its automated
systems under its corporate name, Tooltex, Inc. Tooltex's sales organization
consists of two direct sales personnel, as well as two sales representatives.

Distributors

      Sales of Sonics' products to distributors are also generally made pursuant
to written contracts. Under such contracts, distributors provide repair service
and are prevented from selling devices competitive to the Company's products.
Generally, payments must be made in U.S. dollars within 30 days of delivery of
the product. Distribution arrangements are either exclusive or non-exclusive and
are cancelable upon 30 days notice. The contracts generally exclude private
label sales made by Sonics in the distributor's territory even if the
relationship is of an exclusive type and typically covers sales of both
ultrasonic bonding systems and liquid processor lines. The Company now also
offers both its spin welder and vibration welder to its sales representatives
and distributors. The Company also sells these products directly to end-users or
under private label. The Company usually grants discounts to distributors,
depending on the product and quantity sold. No one distributor accounted for
more than 5% of Sonics' sales in either fiscal year 1997 or 1998. The loss of
such distributors in substantial numbers or at key locations could have a
material adverse effect on the Company's business. USS maintains separate but
similar arrangements with at least three foreign distributors abroad.


          4
<PAGE>

      The Company promotes the sale of its products through direct mailings,
trade shows, product literature, press releases, advertising in trade magazines
and listings in catalogs. The Company occasionally engages in cooperative
advertising with some of its distributors.

      Sonics' wholly owned subsidiary, Vibra-Surge Corporation, will sell its
ultrasonic surgical device through its exclusive distributor of the product,
Sonimedix. Under the distribution contract, Sonimedix is prevented from selling
devices competitive to the ultrasonic surgical instrument. Payment must be made
within 60 days of receipt of the product by the end user. The contract may be
canceled by either party if certain terms and conditions are not satisfied.

Customers

      Sonics sells its products, directly or indirectly, to numerous customers,
ranging in size from small companies to large Fortune 100 corporations. Its
customers are end-users, original equipment manufacturers, system integrators
and resellers as well as distributors. Many of its customers are repeat
purchasers. None of its customers represented more than 5% of Sonics' sales for
fiscal 1997 or 1998.

International Operations

      The Company's international activities are an important portion of its
business. Approximately 37% and 28% of its sales for fiscal years 1997 and 1998,
respectively, are attributable to sales of its products outside the United
States. The Company also operates a branch office in Gland, Switzerland where it
sells and services its ultrasonic devices for the European market except for the
United Kingdom.

      Internationally, the Company sells its ultrasonic products under its own
label to end users and distributors or under the trade name of the distributor.
In most cases, Sonics' devices are shipped to foreign distributors and end users
as completed units. However, in certain situations, especially with regard to
distributors of ultrasonic welders located in Asia and South America, the
Company's systems are made available in kit form and assembled there. Kits
frequently contain all components for devices but in some instances only a
portion of the requisite components is provided. For some foreign sales, no
written distribution arrangement exists.

Competition

      The Company competes in each of its markets against a variety of other
concerns, many of which are larger and have greater financial, technical,
marketing, distribution and other resources than Sonics. It competes on the
bases of service, performance, reliability, price and delivery.

      Prior to making a sale, the Company will expend time and resources
exploring whether it can profitably handle a new application for potential and
existing customers. Generally, the Company receives no compensation for this
pre-sale activity except when special tooling is required and payment for such
services only occurs when and if product sales are consummated. Like nearly all
manufacturers in this industry, the Company invests heavily in this pre-sale
examination of new applications. Such examination represents another area in
which such manufacturers compete, and those with greater resources and manpower
may possess a competitive advantage.

      With respect to its ultrasonic bonding equipment, the Company encounters
competition from Branson Ultrasonics Co. ("Branson"), a subsidiary of Emerson
Electric Co., Dukane Corp. ("Dukane"), Herrmann Ultrasonics, Inc., Forward
Technology Industries, Inc. and other smaller manufacturers. The two dominant
companies in this area are Branson and Dukane. Some of these competitors also
offer spin and vibration devices as well as ultrasonic ones.

      In the ultrasonic liquid processor market, the Company's principal
competitors are Branson and Misonix Inc. Management believes that in this market
Sonics has the largest market share.


          5
<PAGE>

      The Company's ultrasonic surgical instrument has three main competitors,
Mentor Corporation, Lysonix Inc., and Wells-Johnson Corporation. No one company
dominates this market. However, the Company's three major competitors have
entered the market place prior to Sonics.

Backlog

      As of June 30, 1998, the Company's backlog was approximately $2,482,000 as
compared with a backlog of $1,195,000 as of June 30, 1997. No one customer
accounted for more than 10% of such backlog at June 30, 1998.

      Substantially all of the Company's backlog figures are based on written
purchase orders executed by the customer and involve product deliveries and not
engineering services. All orders are subject to cancellation.

Research and Development

      The Company maintains an engineering staff responsible for the improvement
of existing products, modification of products to meet customer needs and the
engineering, research and development of new products and applications.
Engineering and research and development expenses were approximately $418,000
for fiscal 1997 and $544,000 for 1998. The Company attributes this increase to
increased use of outside consulting services for several development projects.
The Company does not expect to use outside consulting services as much in fiscal
1999.

Intellectual Property

      Proprietary information and know-how are important to the Company's
success. Sonics holds no active patents but has trademark protection for its
"Vibra-Cell" trade name and its "Vibra-Surge" trade name. There can be no
assurance that others have not developed, or will not develop, independently the
same or similar information or obtain and use proprietary information of the
Company. Sonics has obtained written assurances from its employees, sales
representatives and distributors under confidentiality agreements regarding its
proprietary information.

      On February 23, 1996, the Company filed a patent application with the U.S.
Patent and Trademark office for one of its bonding machines. However, this
patent application has been abandoned. On May 1, 1997, the Company filed a
patent application and a preliminary patent application with the U.S. Patent and
Trademark Office covering its new ultrasonic surgical instrument. The
preliminary patent application for the ultrasonic surgical instrument has been
abandoned. The Company cannot predict whether a patent for the remaining patent
application will be granted or the extent of protection which would be offered
by a patent, if granted.

      On September 25, 1997, Sonics transferred to its wholly owned subsidiary,
Vibra-Surge Corporation, the "Vibra-Surge" trade name, and its rights and
obligations under the Vibra-Surge patent application and preliminary patent
application. See "Products" above.

Government Regulation

      Sonics' bonding and liquid processor lines generally are not governed by
specific legal rules and laws. The Company's ultrasonic surgical instrument,
however, is subject to a variety of FDA regulations relating to its manufacture
and sale in the United States. The FDA has rules which govern the design,
manufacture, distribution, approval and promotion of medical devices in the
United States.

      Various states and foreign countries in which Sonics' products are, or may
be, sold may impose additional regulatory requirements, such as the Medical
Device Directive in the European Common Market.


          6
<PAGE>

      On May 1, 1997, Sonics filed a patent application and a preliminary patent
application for its ultrasonic surgical instrument, Vibra-Surge. The preliminary
patent application has been abandoned. The Company has obtained 510(k) clearance
from the FDA which permits the Company to market the device for aiding the
removal of soft tissue in general surgery and plastic and reconstructive
surgery. Vibra-Surge has signed an exclusive distribution agreement with
Sonimedix for the sale and marketing of its ultrasonic surgical instrument.

      Sonics' sales abroad may make it subject to other U.S. and foreign laws.
The Company and its agents are also governed by the restrictions of the Foreign
Corrupt Practices Act of 1977, as amended (the "FCPA"). The FCPA prohibits the
promise or payments of any money, remuneration or other items of value to
foreign government officials, public office holders, political parties and
others with regard to obtaining or preserving commercial contracts or orders.
Sonics has urged its foreign distributors to comply with the requirements of the
FCPA. All these restrictions may hamper the Company in its marketing efforts
abroad.

      In addition, other federal, state and local agencies, including those in
the environmental, fire hazard control, and working conditions areas could have
a material adverse affect upon the Company's ability to do business. Sonics is
not involved in any pending or threatened proceedings which would require
curtailment of, or otherwise restrict, its operations because of such
regulations and compliance with applicable environmental or other regulations.
None of these laws has had a material effect upon its capital expenditures,
financial condition or results of operations.

Employees

      As of September 28, 1998, the Company, including its subsidiaries, had 115
full-time employees including its officers, of whom 65 were engaged in
manufacturing, 3 in repair services, 9 in administration and financial control,
16 in engineering and research and development, and 17 in marketing and sales.

      None of Sonics' employees is covered by a collective bargaining agreement
or represented by a labor union. Sonics considers its relationship with its
employees to be good.

      The design and manufacture of the Company's equipment requires substantial
technical capabilities in many disparate disciplines, from mechanics and
computer science to electronics and mathematics. While management believes that
the capability and experience of its technical employees compares favorably with
other similar manufacturers, there can be no assurance that it can retain
existing employees or attract and hire the highly capable technical employees
necessary in the future on favorable terms, if at all.

Company's Statement Regarding Forward Looking Statements

      Any statements in this Annual Report that are not statements of historical
fact are forward-looking statements that are subject to a number of important
risks and uncertainties that could cause actual results to differ materially.
Specifically, any forward looking statements in this Annual Report related to
the Company's objectives of future growth, profitability and financial returns
are subject to a number of risks and uncertainties, including, but not limited
to, risks related to a growing market demand for Sonics' existing and new
products, continued growth in sales and market share of Sonics and its USS
products, pricing, market acceptance of existing and new products, a fluctuation
in the sales product mix, general economic conditions, competitive products, and
product and technology development. There can be no assurance that such
objectives will be achieved. The Company's objectives of future growth,
profitability and financial returns are also subject to the uncertainty of
Vibra-Surge Corporation being able to successfully market its ultrasonic
surgical device. It is also uncertain whether a patent will be granted for the
Company's ultrasonic surgical device, or whether any related patent litigation
may hinder the Company's ability to market the device. In addition, the
Company's objectives of future growth, profitability, and financial returns are
also subject to the uncertainty of the growth and profitability of its wholly
owned subsidiary, Tooltex. It is also uncertain whether the Company's recent
cost cutting measures will result in increased profitability. See "Management's
Discussion and Analysis or Plan of Operation."

Item 2. Description of Property

      The Company's primary manufacturing and office facility is located in
Newtown, Connecticut in one 62,500 square foot steel and cinder block building
(the "Newtown Property"). This facility is considered adequate for the Company's
current needs, as well as its anticipated future requirements. The facility was
purchased on September 19, 1997. The Company renovated the building and
consolidated all of its former Danbury facilities into the Newtown Property in
May of 1998. The Newtown Property was purchased for $1,265,000 and the cost of
improvements to the property was approximately $2,200,000. The Company intends
to lease 7,200 square feet of the building to an unrelated third party. Although
no party has yet been identified, the Company believes that it will be able to
find a lessee because there is minimal competition in Newtown for similar space.
The Newtown Property is insured against fire and other casualty in an amount the
Company believes to be adequate.

      The Newtown Property is encumbered by a first mortgage lien in favor of a
bank ("Bank"), which secures two credit facilities dated September 19, 1997: (i)
a revolving line of credit facility in the original principal amount of up to
$1,500,000 (the "Line of Credit"), (ii) a term loan in the original principal
amount of $427,000 (the "Term Loan"); and (iii) a Bridge Loan in the original
principal amount of $1,600,000. On December 12, 1997, the Company issued
Industrial Revenue Bonds through the Connecticut Development Authority in the
amount of $3,810,000. The proceeds were used in part to pay in full the
outstanding interest and principal due on the Bridge Loan discussed above. The
remaining proceeds were used for the purchase and preparation of the Newtown
Property, and the purchase of new machinery and equipment. The Bonds mature in
November 2017 and bear interest at 75% of the Bank's base lending rate (6.375%
at September 22, 1998). The Company will redeem principal on the Bonds in 228
equal monthly installments of $16,700 beginning December 1998. The Company does
not intend to use the proceeds from the Line of Credit or the Term Loan to
acquire or improve the Newtown Property. For information about such borrowings,
see "Management's Discussion and Analysis or Plan of Operations-Liquidity and
Capital Resources."

      The following table lists the Company's leased offices by location as of
September 25, 1998, and certain other information:

Item 5. Market for Common Equity and Related Stockholder Matters

      From February 27, 1996 to July 24, 1998, the Common Stock and Warrants to
Purchase Common Stock of the Company had been traded and quoted through the
National Association of Securities Dealers Inc. ("NASDAQ") National Market
System under the symbols "SIMA" and "SIMAW," respectively. As of July 24, 1998,
the Company's Common Stock and Warrants to purchase Common Stock have been
traded and quoted through the NASDAQ SmallCap Market under the same symbols used
on NASDAQ's National Market System. The Company transferred to the NASDAQ
SmallCap Market when its Common Stock and Warrants no longer satisfied the
National Market System minimum maintenance requirements for the market
capitalization of the Common Stock's public float.

      The following table sets forth the range of high and low bids for the
Company's Common Stock and Warrants for the periods indicated as reported by
NASDAQ.

                               Stock                     Warrants

      The prices presented in the table are bid prices, which represent prices
between broker-dealers and do not include retail mark-ups and mark-downs or any
commission to the dealer. The prices presented may not reflect actual
transactions.

      On September 24, 1998, the closing price of the Common Stock of the
Company, as reported by the NASDAQ SmallCap Market, was $13/16 per share, and
the closing price of the Warrants, as reported by the NASDAQ SmallCap Market was
$1/16 per Warrant. On September 22, 1998, the Company had 39 stockholders of
record and 13 Warrant holders of record. The Company has been informed by its
registrar and transfer agent that these are holders in nominee name. The Company
believes that the number of beneficial holders is greater.

      The Company intends to follow a policy of retaining any earnings to
finance the development and growth of its business. Accordingly, it does not
anticipate other payments of cash dividends in the foreseeable future. The
payment of dividends, if any, rests within the discretion of the Board of
Directors and will depend upon, among other things, the Company's earnings, its
capital requirements and its overall financial condition.

      In connection with the Company's initial public offering, on June 20, 1996
the Company filed with the Securities and Exchange Commission (the "SEC") a Form
SR reporting the use of proceeds from such offering. Additional Forms SR were
subsequently filed by the Company. As of September 23, 1998, the Company has
applied proceeds from the offering in the following approximate amounts to the
following categories.

                         REPRESENTATIONS AND WARRANTIES

            Section 2.1. Representations by the Authority. The Authority
represents and warrants that:

            (1) It is a body corporate and politic constituting a public
      instrumentality and political subdivision of the State of Connecticut,
      duly organized and existing under the laws of the State including the Act.
      The Authority is authorized to issue the Bonds in accordance with the Act
      and to use the proceeds thereof to finance and refinance the Project.

            (2) The Authority has complied with the provisions of the Act and
      has full power and authority pursuant to the Act to consummate all
      transactions contemplated by the Bonds, the Indenture and the Financing
      Documents.

            (3) By resolution duly adopted by the Authority and still in full
      force and effect, the Authority has authorized the execution, delivery and
      due performance of the Bonds, the Indenture and the Financing Documents,
      and the taking of any and all action as may be required on the part of the
      Authority to carry out, give effect to and consummate the transactions
      contemplated by this Agreement, and all approvals necessary in connection
      with the foregoing have been received.

            (4) The Bonds have been duly authorized, executed, authenticated,
      issued and delivered, constitute valid and binding special obligations of
      the Authority payable solely from revenues or other receipts, funds or
      moneys pledged therefor under the Indenture and from any amounts otherwise
      available under the Indenture, and are entitled to the benefit of the
      Indenture. Neither the State nor any municipality thereof is obligated to
      pay the Bonds or the interest thereon. Neither the faith and credit nor
      the taxing power of the State nor any municipality thereof is pledged for
      the payment of the principal, and premium, if any, of and interest on the
      Bonds.

            (5) The execution and delivery of the Bonds, the Indenture and the
      Financing Documents and compliance with the provisions thereof, will not
      conflict with or constitute on the part of the Authority a violation of,
      breach of or default under its by-laws or any statute, indenture,
      mortgage, deed of trust, note agreement or other agreement or instrument
      to which the Authority is a party or by which the Authority is bound, or,
      to the knowledge of the Authority, any order, rule or regulation


                                      -14-
<PAGE>

      of any court or governmental agency or body having jurisdiction over the
      Authority or any of its activities or properties, and all consents,
      approvals, authorizations and orders of governmental or regulatory
      authorities which are required for the consummation of the transactions
      contemplated thereby have been obtained.

            (6) Subject to the provisions of this Agreement and the Indenture,
      the Authority will apply the proceeds of the Bonds to the purposes
      specified in the Indenture and the Financing Documents.

            (7) There is no action, suit, proceeding or investigation at law or
      in equity before or by any court, public board or body pending or
      threatened against or affecting the Authority, or to the best knowledge of
      the Authority, any basis therefor, wherein an unfavorable decision, ruling
      or finding would adversely affect the transactions contemplated hereby or
      by the Indenture, or which, in any way, would adversely affect the
      validity of the Bonds, the Indenture or the Financing Documents, or any
      agreement or instrument to which the Authority is a party and which is
      used or contemplated for use in consummation of the transactions
      contemplated hereby and by the Indenture.

            (8) It has not made any commitment or taken any action which will
      result in a valid claim for any finders or similar fees or commitments in
      respect of the transactions contemplated by this Agreement.

            (9) The representations of the Authority set forth in the Tax
      Regulatory Agreement delivered concurrently with the execution and
      delivery hereof are by this reference incorporated in this Agreement as
      though fully set forth herein.

            Section 2.2. Representations by the Borrower. The Borrower
represents and warrants that:

            (1) The Borrower has been duly incorporated and validly exists as a
      corporation in good standing under the laws of the State of Delaware and
      duly qualified to do business as a foreign corporation in the State of
      Connecticut, is not in violation of any provision of its certificate of
      incorporation or its by-laws, has power to enter into and perform the
      Financing Documents, and by proper corporate action has duly authorized
      the execution and delivery of the Financing Documents.

            (2) The Financing Documents constitute valid and legally binding
      obligations of the Borrower, enforceable in accordance with their
      respective terms, except as such


                                      -15-
<PAGE>

      enforceability may be limited by bankruptcy, insolvency, fraudulent
      conveyance, reorganization, moratorium or similar laws affecting
      creditors' rights and remedies generally or by general equitable
      principles (whether applied by a court or law or equity).

            (3) Neither the execution and delivery of the Financing Documents,
      the consummation of the transactions contemplated thereby, nor the
      fulfillment by the Borrower of or compliance by the Borrower with the
      terms and conditions thereof is prevented or limited by or conflicts with
      or results in a breach of, or default under the terms, conditions or
      provisions of any contractual or other restriction on the Borrower,
      evidence of its indebtedness or agreement or instrument of whatever nature
      to which the Borrower is now a party or by which it is bound, or
      constitutes a default under any of the foregoing. No event has occurred
      and no condition exists which, upon the execution and delivery of any
      Financing Documents, constitutes an Event of Default hereunder or an event
      of default thereunder or, but for the lapse of time or the giving of
      notice, would constitute an Event of Default hereunder or an event of
      default thereunder.

            (4) There is no action or proceeding pending or, to the knowledge of
      the Borrower, threatened against the Borrower before any court,
      administrative agency or arbitration board that may materially and
      adversely affect the ability of the Borrower to perform its obligations
      under the Financing Documents and all authorizations, consents and
      approvals of governmental bodies or agencies required in connection with
      the execution and delivery of the Financing Documents and in connection
      with the performance of the Borrower's obligations hereunder or thereunder
      have been obtained, except for such authorizations, consents or approvals
      that can only be attained after the commencement of, or the completion of,
      the Project.

            (5) The execution, delivery and performance of the Financing
      Documents and any other instrument delivered by the Borrower pursuant to
      the terms hereof or thereof are within the corporate powers of the
      Borrower and have been duly authorized and approved by the board of
      directors of the Borrower and are not in contravention of law or of the
      Borrower's certificate of incorporation or by-laws, as amended to date, or
      of any undertaking or agreement to which the Borrower is a party or by
      which it is bound.

            (6) The Borrower represents that it has not made any commitment or
      taken any action which will result in a valid claim for any finders' or
      similar fees or


                                      -16-
<PAGE>

      commitments in respect of the transactions described in this Agreement.

            (7) The Project is included within the definition of a "project" in
      the Act, and its estimated cost is equal to or in excess of $3,810,000.
      The Borrower intends the Project to be and to continue to be an authorized
      project under the Act during the Term.

            (8) All amounts shown in Schedule D-1 of the Tax Regulatory
      Agreement are eligible costs of a project financed by bonds issued by the
      Authority under the Act, and may be financed by amounts in the Project
      Fund under the Indenture. None of the proceeds of the Bonds will be used
      directly or indirectly as working capital or to finance inventory.

            (9) The Project is in material compliance with all applicable
      federal, State and local laws and ordinances (including rules and
      regulations) relating to zoning, building, safety and environmental
      quality. The Borrower intends to proceed with due diligence to complete
      the Project pursuant to Section 4.1 hereof.

            (10) The availability of financial assistance from the Authority as
      provided herein and in the Indenture has induced the Borrower to locate
      the Project in the State. The Borrower does not intend to lease the
      Project, except in the ordinary course of business of the Borrower.

            (11) The Borrower will not take or omit to take any action which
      action or omission will in any way cause the proceeds of the Bonds to be
      applied in a manner contrary to that provided in the Indenture and the
      Financing Documents as in force from time to time.

            (12) The Borrower has not taken and will not take any action and
      knows of no action that any other person, firm or corporation has taken or
      intends to take, which would cause interest on the Bonds to be includable
      in the gross income of the recipients thereof for federal income tax
      purposes. The representations, certifications and statements of reasonable
      expectation made by the Borrower in the Tax Regulatory Agreement, dated
      the date of delivery hereof and relating to the Project description,
      composite issues, bond maturity and average asset economic life, use of
      Bond proceeds, arbitrage and related matters are hereby incorporated by
      this reference as though fully set forth herein.

            (13) The Borrower has good and marketable title in fee simple to the
      Project Realty, subject only to


                                      -17-
<PAGE>

      Permitted Encumbrances, sufficient for the purposes of this Agreement.

            (14) The Borrower has obtained a standard American Land Title
      Association ("ALTA") title insurance policy from a title insurance company
      satisfactory to the Trustee in an amount at least equal to the face amount
      of the Initial Bond (or such lesser amount as shall be approved by the
      Original Purchaser) insuring the Authority and the Trustee on behalf of
      the Bondholders as their respective interests may appear, and containing
      only such exceptions as have been approved by an Authorized Representative
      of the Authority and the Trustee.

            (15) The Borrower has good and merchantable title to the Project
      Equipment owned by the Borrower as of the date hereof, free and clear of
      liens and encumbrances except for Permitted Encumbrances.

            (16) As of the date hereof, neither the Borrower, nor to its
      knowledge anyone acting on behalf of the Borrower, has entered into
      negotiations with any person for the purpose of undertaking any borrowing
      concurrently with or subsequent to the issuance of the Initial Bonds and
      to be secured wholly or partially by a lien or encumbrance on the Project
      or any part thereof, and the Borrower has no present intention of
      undertaking any such borrowing, except in connection with the requirements
      described in the Borrower's application to the Authority.

            (17) The representations of the Borrower set forth in the Tax
      Regulatory Agreement delivered concurrently with the execution and
      delivery hereof are by this reference incorporated in this Agreement as
      though fully set forth herein.

                                   ARTICLE III

                                    THE LOAN

            Section 3.1. Loan Clauses. (A) Subject to the conditions and in
accordance with the terms of this Agreement, the Authority agrees to make a loan
to the Borrower from the proceeds of the Initial Bonds in the amount of
$3,810,000 and the Borrower agrees to borrow such amount from the Authority.

            (B) The loan shall be made at the time of delivery of the Initial
Bonds and receipt of payment therefor by the Authority against receipt by the
Authority of the initial Note duly executed and delivered to evidence the
pecuniary indebtedness of the Borrower hereunder. Any additional loan shall be
made at the time of delivery of the applicable series of Additional Bonds and
receipt of payment therefor by the Authority against receipt by the Authority of
a supplemental Note duly executed and delivered to evidence the additional
pecuniary indebtedness of the Borrower hereunder. As and for the loan the
Authority shall deposit the proceeds of the Initial Bonds into the Debt Service
Fund and the Project Fund as provided in the Indenture and such proceeds shall
be held, and invested and disbursed as provided in the Indenture on the terms
and conditions therein prescribed.

            (C) On or before each due date for the payment of the principal of
or interest on the Bonds, until the principal or Redemption Price, if any, of
and interest on the Bonds shall have been fully paid or provision for the
payment thereof shall have been made in accordance with the Indenture, the
Borrower shall make loan payments to the Trustee for the account of the
Authority in an amount which, when added to any moneys then on deposit in the
Debt Service Fund and available therefor, shall be equal to the amount payable
on such due date with respect to the Bonds as provided in Section 5.3 of the
Indenture, including amounts due for the payment of the principal of and
interest on the Bonds. In addition, the Borrower shall pay to the Trustee, as
and when the same shall become due, all other amounts due under the Financing
Documents, together with interest thereon at the then applicable rate as set
forth herein. The Borrower shall have the option to prepay its loan obligation
in whole or in part at the times and in the manner provided in Article VIII
hereof.

            (D) [Reserved]

            (E) Anything herein to the contrary notwithstanding, any amount at
any time held in the Principal and Interest Account of the Debt Service Fund by
the Trustee pursuant to this Section shall be credited against the next
succeeding loan payment obligation of the Borrower as provided in subsection
3.1(C) hereof. If, on any due date for payments with respect to the Bonds, the
balance in the Debt Service Fund is insufficient to make such payments, the


                                      -19-
<PAGE>

Borrower agrees forthwith to pay the amount of the deficiency. If at any time
the amount held by the Trustee in the Debt Service Fund shall be sufficient to
pay or provide for the payment of the Bonds in accordance with Section 12.1 of
the Indenture, the Borrower shall not be obligated to make any further payments
under the foregoing provisions.

            Section 3.2. Other Amounts Payable. (A) The Borrower hereby further
expressly agrees to pay to the Trustee as and when the same shall become due,
(i) an amount, as may be agreed upon from time to time between the Borrower and
the Trustee and/or the Paying Agent, equal to the initial and annual fees of the
Trustee for the ordinary services of the Trustee rendered and its ordinary
expenses incurred under the Indenture, including fees and expenses as registrar
and in connection with the preparation of new Bonds upon exchanges or transfers,
and the fees and expenses of the Trustee and any Paying Agents on the Bonds for
acting as paying agents as provided in the Indenture, including the reasonable
fees and expenses of its counsel and (ii) the reasonable fees and expenses of
the Trustee for extraordinary services rendered by it and extraordinary expenses
incurred by it under the Indenture, including reasonable counsel fees and
expenses (iii) the reasonable fees and expenses of the Authority, including the
reasonable fees and expenses of its counsel, incurred by the Authority as a
result of an Event of Default or otherwise enforcing this Agreement, (iv) the
reasonable fees and expenses of the Bondholder as a result of an Event of
Default or otherwise enforcing this Agreement and for any consent, waiver or
amendment relating to the Indenture or any of the Financing Documents, including
reasonable fees and expenses of counsel for such Bondholders, and (v) any other
sums required to be paid by the Borrower under the terms of the Indenture and
the Note.

            (B) The Borrower also agrees to pay all amounts payable by it under
the Tax Regulatory Agreement, including any expenses of the Authority incurred
in connection with rebate compliance pursuant to the Tax Regulatory Agreement,
and the Financing Documents at the time and in the manner therein provided.

            (C) The Borrower also agrees to fund, replenish and maintain all
amounts required to be funded, replenished and maintained in the Funds and
Accounts established in and as required by Article V of the Indenture.

            (D) The Borrower also agrees to pay directly to the Authority on the
date of issuance of the Bonds a fee equal to 1/2 of 1% of the principal amount
of the Initial Bonds, such fee to be payable, without notice, demand or invoice
of any kind at the Authority's address as set forth herein or at such other
address and to the attention of such other person, or to such account as the
Authority may stipulate by written notice to the Borrower.


                                      -20-
<PAGE>

            (E) The Borrower also agrees to perform all obligations required to
be performed by it under the Indenture in accordance with its terms.

            (F) The Borrower also agrees to pay, or cause to be paid, when due,
any amounts necessary to redeem Bonds which have been called for redemption
under the Indenture (including, if any applicable premiums thereon).

            Section 3.3. Manner of Payment. The payments provided for in Section
3.1 hereof shall be made by any reasonable method providing immediately
available funds at the time and place of payment directly to the Trustee for the
account of the Authority and shall be deposited in the Debt Service Fund. The
additional payments provided for in Section 3.2 shall be made in the same manner
directly to the entitled party or to the Trustee for its own use or disbursement
to the Paying Agents, as the case may be.

            Section 3.4. Direct Payment to Original Purchaser. Notwithstanding
the provisions of this Loan Agreement to the contrary, so long as the Original
Purchaser is the owner of the Initial Bonds, the Borrower shall pay that portion
of the loan payments relating to the principal and redemption price of, and
interest on, the Initial Bonds directly to the Original Purchaser as provided in
Section 2.3(F) of the Indenture. In the event that the Borrower shall fail to
pay any installment of the loan payments so payable to the Original Purchaser in
accordance with this Section, interest on such overdue payment shall accrue from
the due date thereof at a rate equal to the Taxable Rate (as defined in the
Indenture).

            Section 3.5. Obligation Unconditional. The obligations of the
Borrower under the Financing Documents shall be absolute and unconditional,
irrespective of any defense or any rights of setoff, recoupment or counterclaim
it might otherwise have against the Authority or the Trustee. The Borrower will
not suspend or discontinue any such payment or terminate this Agreement (other
than in the manner provided for hereunder) for any cause, including, without
limiting the generality of the foregoing, any acts or circumstances that may
constitute failure of consideration, failure of title, or commercial frustration
of purpose, or any damage to or destruction of the Project, or the taking by
eminent domain of title to or the right of temporary use of all or any part of
the Project, or any change in the tax or other laws of the United States, the
State or any political subdivision of either thereof, or any failure of the
Authority or the Trustee to perform and observe any agreement or covenant,
whether expressed or implied, or any duty, liability or obligation arising out
of or connected with the Financing Documents.

            Section 3.6. Security Clauses. (A) The Authority hereby notifies the
Borrower and the Borrower acknowledges that, among other things, the Borrower's
loan payments and all of the


                                      -21-
<PAGE>

Authority's right, title and interest under the Financing Documents to which it
is a party (except its rights under Sections 6.2, 6.4 and 7.3 hereof) are being
concurrently with the execution and delivery hereof endorsed, pledged and
assigned without recourse by the Authority to the Trustee as security for the
Bonds as provided in the Indenture.

            (B) In order to further secure its loan obligation hereunder, the
Borrower has executed and delivered to the Authority and the Original Purchaser
the Mortgage and the Security Agreement. The Borrower hereby acknowledges and
consents to the assignment thereof to the Trustee as security for the payment of
the Bonds according to their tenor and effect.

            (C) From time to time, at the request of the Authority or the
Trustee, the Borrower shall obtain, execute and deliver one or more financing
statements and other instruments, and shall do all other acts and things, as the
Authority or the Trustee deems necessary or desirable in order to fully secure
its interest in Project Equipment acquired after the date hereof and to
effectuate the transactions contemplated hereby.

            (D) The Authority and the Borrower acknowledge that buildings or
improvements on the Project Realty are in the process of construction or repair
or are to be erected or repaired, that the Authority has agreed to make the
proceeds of the Bonds available to the Borrower in installments as the work
progresses and to pay over any balance of the proceeds remaining upon the
completion of the Project in accordance with Section 5.2 of the Indenture and
that the Borrower has agreed to complete the erection or repair of the buildings
and improvements to the satisfaction of the Authority in accordance with Article
IV hereof.

            This Agreement shall constitute a security agreement within the
meaning of the Connecticut Uniform Commercial Code. In addition to all other
rights and remedies hereunder, the Authority and the Trustee as its assignee
shall have all rights and remedies of a secured party under the Connecticut
Uniform Commercial Code.

            Section 3.7. Issuance of Initial Bonds. The Authority has
concurrently with the execution and delivery hereof sold and delivered the
Initial Bonds under and pursuant to a resolution adopted by the Authority on
November 19, 1997, authorizing their issuance under and pursuant to the
Indenture. The proceeds of sale of the Initial Bonds shall be applied as
provided in Articles IV and V of the Indenture.

                            INSURANCE, CONDEMNATION,
                             DAMAGE AND DESTRUCTION

            Section 5.1. Insurance Requirements.

            (A) The Borrower covenants that, following completion of the Project
(or at such earlier time as may be specified in this Section 5.1) it shall
provide or cause to be provided and to maintain continuously, or cause to be
maintained continuously during the term of this Agreement, the following types
and amounts of insurance, subject to the proviso in Subsection (B) below.

            (1) Insurance against loss and/or damage to the Mortgaged Property
      under a policy or policies in form and amount covering such risks as are
      ordinarily insured against by similar facilities, including without
      limiting the generality of the foregoing, fire, wind, and lightning and
      uniform standard extended coverage endorsements, limited only as may be
      provided in the standard form of extended coverage endorsements at the
      time in use in Connecticut. Such insurance shall be for an amount at least
      equal to the lesser of the replacement cost or the full insurable value of
      the Mortgaged Property or the principal of the Outstanding Bonds. No
      policy of insurance shall be so written that the proceeds thereof will
      produce less than the minimum coverage required by the preceding sentence,
      by reason of co-insurance provisions or otherwise, without the prior
      consent thereto in writing by the Trustee, except that each policy of
      insurance required hereunder may contain a loss deductible clause
      specifying such sum or sums as the Borrower may determine as the sum or
      sums to be deducted from the amount of loss resulting from particular
      perils. The Trustee shall consent to such coinsurance or other like
      reductions.

            (2) Business interruption insurance, protecting the Borrower and the
      Trustee, covering the Borrower's payments due under this Agreement and the
      salaries and expenses of key personnel and other minimum operating
      expenses required for the operation of the Mortgaged Property during such
      period or periods not less than twelve (12) months following damage or
      destruction of the Mortgaged Property by one of the hazards insured
      against by the insurance provided for in paragraph (A)(1) above.

            (3) Commencing with the date of settlement for the Initial Bonds,
      public liability insurance (including interests of the Borrower) and
      automobile liability insurance, in an occurrence form, in the minimum
      amount


                                      -27-
<PAGE>

      of $1,000,000 bodily injury and property damage combined single limit and
      aggregate where applicable.

            (4) Worker's compensation and employer's liability insurance meeting
      the Borrower's statutory obligations; provided, however, that, if the
      Borrower becomes an approved self-insured, employer's liability coverage
      in the amount of at least $100,000 shall be purchased.

            (5) Boiler and machinery coverage (direct damage and use and
      occupancy) on a replacement cost basis where deemed advisable by the
      Borrower, or where otherwise required.

            (6) Excess liability coverage in the amount of at least either
      straight excess or umbrella excess, covering excess of paragraphs (3) and
      (8) to be maintained in force so that the total coverage available under
      each of the aforementioned paragraphs, including this subsection, is not
      less $5,000,000 per occurrence and in the aggregate, where applicable, as
      excess of employer's liability, general liability, professional liability
      and automobile liability coverage.

            (B) All policies of insurance and bonds required by this Section
5.1: shall be in such amounts and shall contain such provisions as comply with
the foregoing requirements; and in every applicable case shall contain standard
mortgagee clauses; provided, however, that the Borrower shall not be required to
provide insurance coverage which, is for risks not normally covered or is in
excess of standard requirements, if any, for facilities similar in size,
location and nature to the Mortgaged Property. All policies and bonds shall
provide, so far as the same may be obtainable without the payment of additional
premium, that coverage shall not be canceled without thirty (30) days' prior
written notice to the Trustee.

            (C) All policies of insurance and bonds shall be issued by
responsible insurance or surety companies, acceptable to the Borrower, qualified
to do business in Connecticut and qualified under the laws of Connecticut to
assume risks covered by such policy or policies or bond or bonds and shall be
non-assessable.

            (D) All policies of insurance required under paragraphs (A)(1), (2),
and (5) above shall be for the benefit of the Borrower and the Trustee, as their
respective interests may appear, and shall be made payable to the Trustee. The
Trustee shall have the exclusive right after obtaining the advice and consent of
the Borrower which shall not be unreasonably withheld (and after the occurrence
of an Event of Default, without notice to or consent of the Borrower) to receive
the proceeds from such insurance and settle and receipt for claims thereunder.
Policies evidencing the insurance required by paragraphs (A)(3), (4) and (6)
above shall


                                      -28-
<PAGE>

be for the benefit of the Borrower. The Borrower shall have the right to receive
payments due and to receipt for claims under policies of insurance and fidelity
bonds required by subparagraph (A)(3), (4), and (6) above. The original or a
copy of each policy or bond or a certificate that the same has been issued and
is currently in effect shall be delivered to the Trustee.

            (E) In the event that any insurance required by this Section 5.1 is
not commercially available at a reasonable cost or has been otherwise provided,
the Trustee shall accept such substitute coverage, if any.

            (F) In the event that the Borrower fails to maintain, or cause to be
maintained, any insurance as provided in this Section 5.1, the Trustee may (but
shall be under no obligation to), upon such notice to the Borrower as is
reasonable under the circumstances, procure and maintain such insurance, and any
amounts so advanced therefor by the Trustee shall become an additional
obligation of the Borrower secured by this Agreement, which amounts, together
with interest thereon at one percent above the prime rate of the Trustee from
the date thereof, the Borrower agrees and covenants to pay.

            Section 5.2. Casualty; Condemnation; Loss of Title. If the Mortgaged
Property shall be wholly or partially destroyed or damaged by fire or other
casualty covered by insurance required under Section 5.1(A)(1) or (5), or if the
Mortgaged Property shall be wholly or partially condemned, taken or injured by
any person, including any person possessing the right to exercise the power of
or a power in the nature of eminent domain or transferred to such a person, by
way of a conveyance in lieu of the exercise of such a power by such person, or
if any part of the Mortgaged Property shall be lost because of failure of title,
the Borrower covenants that it will take all actions and will do all things
which may be necessary to enable recovery to be made upon such policies of
insurance or on account of such taking, condemnation, conveyance, damage, injury
or loss of title in order that moneys due on account of losses suffered may be
collected and paid to the Trustee. Any appraisement or adjustment of loss or
damage and any settlement or payment therefor, which may be agreed upon by the
Borrower and the appropriate insurer or condemnor or person, shall be evidenced
to the Trustee by a certificate signed by an Authorized Borrower Representative.
The Trustee may rely conclusively upon such certificate.

            Section 5.3. Proceeds of Hazard Insurance.

            (A) Immediately after the occurrence of loss or damage covered by
insurance required under Section 5.1(A)(1) or (5), the Borrower shall notify the
Authority, the Architect, and the Trustee in writing. The Architect promptly
shall determine and advise the Authority, the Trustee, and the Borrower, in
writing, whether it is practicable to repair, reconstruct or replace such
damaged or


                                      -29-
<PAGE>

destroyed or condemned or lost property and, if so, the estimated time and funds
required for such repair, reconstruction or replacement.

            (B) If the Architect shall advise that such repair, reconstruction
or replacement is practicable, and if, within ninety (90) days from the receipt
of the Architect's report (or such later date as may be reasonably acceptable to
the Trustee), the Borrower delivers to the Trustee (i) an executed construction
contract for such work at a price not greater than the amount stated in such
Architect's report and (ii) cash or an irrevocable letter of credit in an amount
equal to the funds, if any, required by such Architect's report in excess of the
available net insurance proceeds, then the Borrower shall promptly proceed to
repair, reconstruct and replace such part of the Mortgaged Property, including
all fixtures, furniture, equipment and affects, to its original condition
insofar as possible. The moneys required for such repair, reconstruction and
replacement shall be paid from: (x) the net proceeds of insurance (other than
proceeds of business interruption insurance which shall be applied as provided
in Subsection (D) below) received by reason of such occurrence, which net
proceeds (after deducting any reasonable expenses incurred by the Trustee or the
Borrower in collecting the same, the "Net Insurance Proceeds") shall be
deposited into the Project Fund and disbursed in accordance with the requisition
procedure established for the Project Fund under Section 5.2(C) of the
Indenture; and (y) to the extent such Net Insurance Proceeds are not sufficient,
from moneys to be provided by the Borrower. Notwithstanding the foregoing, if
the Architect's estimate of the cost of such repair, reconstruction or
replacement is $50,000 or less, the Borrower shall not be required to deliver
the construction contract and funds and items referred to in clauses (i) and
(ii) above, the Net Insurance Proceeds shall be paid to the Borrower and the
Borrower shall promptly proceed with such repair, reconstruction or replacement.
Any Net Insurance Proceeds remaining after the completion of such repair,
replacement or reconstruction shall be paid to the Borrower.

            (C) If the Architect advises that such repair, reconstruction or
replacement is not practicable, or not appropriate given the damaged property's
age or lack of marketability or if the Architect's report and the other
documents described in Subsection (B) above are not delivered within the
required time period, then the parties hereto agree that all respective Net
Insurance Proceeds shall be deposited in the Redemption Account and applied to
the redemption of Bonds pursuant to Section 2.4(B) of the Indenture, and the
Borrower shall pay to the Trustee prior to the redemption date any additional
amount required to effect such redemption; provided, that in the case of damage
to or destruction of all or substantially all of the Mortgaged Property, the
Borrower shall pay to the Trustee an amount sufficient, together with the Net
Insurance Proceeds, to redeem all Bonds Outstanding.


                                      -30-
<PAGE>

            (D) The proceeds of business interruption insurance required by
Section 5.1(A)(2) shall be deposited in the Debt Service Fund and applied to the
payment of the principal of and interest on the Bonds.

            Section 5.4. Eminent Domain. Immediately after the commencement of
any condemnation or similar proceedings by a third party in the exercise of a
power of eminent domain, or a power in the nature of eminent domain affecting
the Mortgaged Property the Borrower shall notify the Authority, the Trustee and
the Architect in writing.

            (A) The proceeds of any condemnation award or other compensation
paid by reason of a conveyance in lieu of the exercise of such power (after
deducting any costs or expenses incurred by the Trustee or the Borrower in
collecting the same, the "Net Condemnation Proceeds") received with respect to
all or substantially all the Mortgaged Property shall be paid to the Trustee for
deposit in the Redemption Account and applied to the redemption of all
Outstanding Bonds pursuant to Section 2.4(B) of the Indenture, and the Borrower
shall pay to the Trustee prior to the redemption date any additional amount
required to effect such redemption. Any Net Condemnation Proceeds received for a
taking of less than substantially all of the Mortgaged Property shall be applied
as provided in Subsections (B) and (C) below.

            (B) If Net Condemnation Proceeds do not exceed $500,000, and if the
Borrower certifies to the Trustee that the efficient utilization of the
Mortgaged Property has not been impaired, notwithstanding such taking, then the
Net Condemnation Proceeds shall be paid to the Borrower.

            (C) If the Net Condemnation Proceeds exceed $500,000:

            (1) The Borrower may elect to replace or restore the portion of the
      Mortgaged Property affected by such taking or conveyance, in which event
      the Borrower shall promptly proceed to replace or restore such portion of
      the Mortgaged Property, including any fixtures, furniture, equipment and
      effects, to its original usefulness and condition insofar as possible,
      provided that the Borrower has delivered to the Trustee within ninety (90)
      days of receipt of such condemnation award (or by such later date as may
      be reasonably acceptable to the Trustee) (i) a written report of the
      Architect stating such Architect's estimate of the cost of replacing or
      restoring the portion of the Mortgaged Property affected by such taking or
      conveyance, (ii) an executed construction contract for such work at a
      price not greater than the amount stated in such Architect's report and
      (iv) cash or an irrevocable letter of credit in an amount equal to the
      funds, if any, required by such Architect's report in excess of the
      available Net


                                      -31-
<PAGE>

      Condemnation Proceeds and (v) the items described in Section 4.1(J) and
      (K). The moneys required for such replacement or restoration shall be
      paid: (x) from the Net Condemnation Proceeds which shall be deposited into
      the Project Fund and disbursed in accordance with the requisition
      procedure established for the Project Fund under Section 5.2(C) of the
      Indenture; and (y) to the extent that such proceeds are not sufficient,
      from moneys to be provided by the Borrower; or

            (2) The Borrower may elect to have all or part of such Net
      Condemnation Proceeds deposited in the Redemption Account and applied by
      the Trustee to the redemption of Outstanding Bonds, and the Borrower shall
      pay any additional amount required to effect such redemption.

If the report of the Architect required by the preceding paragraph are not
delivered within the required time period, then the Net Condemnation Proceeds
shall be deposited in the Redemption Account and applied to the redemption of
all Outstanding Bonds pursuant to Section 2.4(B) of the Indenture, and the
Borrower shall pay to the Trustee prior to the redemption date any additional
amount required to effect such redemption.

            Section 5.5. Reserved.

            Section 5.6. No Abatement of Payments Hereunder. If the Project
Realty or the Project Equipment shall be damaged or either partially or totally
destroyed, or if title to or the temporary use of the whole or any part thereof
shall be taken or condemned by a competent authority for any public use or
purpose, there shall be no abatement or reduction in the amounts payable by the
Borrower hereunder and the Borrower shall continue to be obligated to make such
payments. In any such case the Borrower shall promptly give written notice
thereof to the Authority and the Trustee.

            (D) All covenants, stipulations, promises, agreements and
obligations of the Authority, the Trustee and the Original Purchaser contained
herein shall be deemed to be the covenants, stipulations, promises, agreements
and obligations of the Authority and the Trustee and not of any member,
director, officer or employee of the Authority or the Trustee in its individual
capacity, and no recourse shall be had for the payment of the Bonds or for any
claim based thereon or hereunder against any member, director, officer or
employe of the Authority or the Trustee or any natural person executing the
Bonds.

            (E) In case any action shall be brought against one or more of the
Indemnified Parties based upon any of the above and in respect of which
indemnity may be sought against the Borrower, such Indemnified Party shall
promptly notify the Borrower in writing, enclosing a copy of all papers served,
but the omission so to notify the Borrower of any such action shall not relieve
it of any liability which it may have to any Indemnified Party otherwise than
under this Section 6.2. In case any such action shall be brought against any
Indemnified Party and it shall notify the Borrower of the commencement thereof,
the Borrower shall be entitled to participate in and, to the extent that it
shall wish, to assume the defense thereof with counsel satisfactory to such
Indemnified Party, and after notice from the Borrower to such Indemnified Party
of the Borrower's election so to assume the defense thereof, the Borrower shall
not be liable to such Indemnified Party for any subsequent legal or other
expenses attributable to such defense except as provided below, other than
reasonable costs of investigation subsequently incurred by such Indemnified
Party in connection with the defense thereof. The Indemnified Party shall have
the right to employ its own counsel in any such action, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party
unless (i) the employment of counsel by such Indemnified Party has been
authorized by the Borrower, (ii) the Indemnified Party shall have reasonably
concluded that there may be a conflict of interest between the Borrower and the
Indemnified Party in the conduct of the defense of such action (in which case
the Borrower shall not have the right to direct the defense of such action on
behalf of the Indemnified Party) or (iii) the Borrower shall not in fact have
employed counsel satisfactory to the Indemnified Party to assume the defense of
such action.

            (F) The Borrower also agrees to pay all reasonable or necessary
out-of-pocket expenses of the Authority in connection with the issuance of the
Bonds, the administration of the Financing Documents and the enforcement of its
rights thereunder, including particularly any fees, charges and expenses
(including counsel fees) incurred by the Authority in connection with matters of
title, collateral security and financing and continuation statements.

            (G) In the event the Borrower fails to pay any amount or perform any
act under the Financing Documents, within ten (10)


                                      -34-
<PAGE>

Business Days following receipt of written notice, the Trustee or Authority may
pay the amount or perform the act, in which event the costs, disbursements,
expenses and reasonable counsel fees thereof, together with interest thereon
from the date the expense is paid or incurred at the prime interest rate
publicly announced from time to time by the Trustee as a commercial bank plus 2%
shall be an additional obligation hereunder payable on demand by the Authority
or the Trustee.

            (H) Any obligation of the Borrower to the Authority under this
Section shall be separate from and independent of the other obligations of the
Borrower hereunder, shall not be secured by the Financing Documents, and may be
enforced directly by the Authority or the Trustee against the Borrower
irrespective of any action taken by or on behalf of the Bondholders.

            (I) The obligations of the Borrower under this Section,
notwithstanding any other provisions contained in the Financing Documents, shall
survive the termination of this Agreement and, shall be recourse to the
Borrower, and for the enforcement thereof each Indemnified Party shall have
recourse to the general credit of the Borrower.

            Section 6.3. Incorporation of Tax Regulatory Agreement; Payments
Upon Taxability. (A) The representations warranties, covenants and statements of
expectation of the Borrower set forth in the Tax Regulatory Agreement are by
this reference incorporated in this Agreement as though fully set forth herein.

            (B) If any Bondholder receives from the Internal Revenue Service a
notice of assessment and demand for payment with respect to interest on any Bond
which when issued purported to be not subject to such assessments or demands, an
appeal may be taken by the Bondholder at the option of either the Bondholder or
the Borrower. In either case all expenses of the appeal including reasonable
counsel fees shall be paid by the Borrower, and the Bondholder and the Borrower
shall cooperate and consult with each other in all matters pertaining to any
such appeal, except that no Bondholder shall be required to disclose or furnish
any non-publicly disclosed information, including, without limitation, financial
information and tax returns. Before the taking of any appeal, however, the
Bondholder shall have the right to require the Borrower to pay the tax assessed
and conduct the appeal as a contest for reimbursement.

            (C) Not later than sixty days following a Determination of
Taxability, the Borrower shall pay to the Trustee an amount sufficient, when
added to the amount then in the Debt Service Fund and available for such
purpose, to retire and redeem all Bonds then Outstanding, in accordance with
Section 2.4 of the Indenture.

            (D) In the event that any Bonds are paid at maturity, or in the
event any Bonds are purchased by the Borrower, or purchased


                                      -35-
<PAGE>

by the Trustee pursuant to subsection 5.3(E) of the Indenture, or in the event
any Bonds are redeemed by application of Scheduled Payments or otherwise
subsequent to the Tax Incidence Date without the Bondholder entitled thereto
receiving payment of an amount at least equal to the applicable Redemption Price
thereof, plus accrued interest to the redemption date at the rate applicable
following a Determination of Taxability, and other amounts required to be paid
hereunder, the Borrower shall, promptly upon receipt from the Trustee of a
notice to that effect, pay to the Trustee for payment to the former Bondholders
entitled thereto an amount equal to the difference between the amount actually
applied to the payment, purchase or redemption of such Bonds and the applicable
Redemption Price thereof, plus accrued interest to the redemption date at the
rate applicable following a Determination of Taxability, and other amounts
required to be paid hereunder.

            (E) The obligation of the Borrower to make the payments provided for
in this Section shall be absolute and unconditional, and the failure of the
Authority or the Trustee to execute or deliver or cause to be delivered any
documents or to take any action required under this Agreement or otherwise shall
not relieve the Borrower of its obligation under this Section. Notwithstanding
any other provision of this Agreement or the Indenture, the Borrower's
obligations under this Section shall survive the termination of this Agreement
and the Indenture.

            (F) The occurrence of a Determination of Taxability shall not
constitute an Event of Default hereunder but shall require only the performance
of the obligations of the Borrower stated in this Section, the breach of which
shall constitute an Event of Default as provided in Section 7.1 hereof.

            Section 6.4. Public Purpose Covenants. (A) The Borrower covenants
that it will complete the Project in accordance with Section 4.1 hereof, and
that it will operate the Project Realty and the Project Equipment for the
purposes and in a manner consistent with the Borrower's application for
assistance to the Authority. The Borrower further covenants and agrees that it
will, throughout the term of this Agreement, (1) comply with all applicable
laws, regulations, ordinances, rules, and orders relating to the Project Realty
or the Project Equipment as provided in the Financing Documents, (2) maintain
and insure the Project Realty or the Project Equipment and pay all taxes,
payments-in-lieu-of-taxes, assessments and other governmental charges in
accordance with the Financing Documents, (3) not cause or permit the Project
Realty or the Project Equipment to become or remain a public nuisance, (4) not
allow any change in the nature of the occupancy, use or operation of the Project
Realty or the Project Equipment which is substantially inconsistent with the
Borrower's application for assistance to the Authority, except that the Borrower
may after notice to the Authority permit any such change which does not
disqualify the Project as an authorized project under the Act as in effect on
the date hereof and (5)


                                      -36-
<PAGE>

except as otherwise provided herein, not sell, assign, convey, lease or
otherwise dispose of its interest in the Project Realty or the Project Equipment
without the prior written consent of the Authority. Nothing in this Section is
intended to require the Borrower to operate the Project Realty or the Project
Equipment in such manner as, in the good faith judgment of the Borrower, shall
materially and adversely impair the operating results of the Borrower in
connection with the use of the Project Realty or the Project Equipment.

            (B) A breach of any covenant contained in this Section 6.4 shall
constitute an Event of Default, but shall permit only the exercise by the
Authority of the remedies provided in Section 7.3 hereof.

            (C) The obligations of the Borrower under this Section, and all
others contained in the Financing Documents, shall be recourse to the Borrower,
and for the enforcement thereof the Authority shall have recourse to the general
credit of the Borrower.

            Section 6.5. Further Assurances and Corrective Instruments. The
Authority and the Borrower agree that they will, from time to time, execute,
acknowledge and deliver, or cause to be executed, acknowledged and delivered,
such supplements hereto and such further instruments as may reasonably be
required for correcting any inadequate or incorrect description of the Project
Realty or the Project Equipment or for carrying out the intention of or
facilitating the performance of this Agreement, provided that no such supplement
or instrument shall alter Borrower's rights or obligations under the Financing
Documents.

            Section 6.6. Covenant by Borrower as to Compliance with Indenture.
The Borrower covenants and agrees that it will comply with the provisions of the
Indenture with respect to the Borrower and that the Trustee and the Bondholders
shall have the power and authority provided in the Indenture. The Borrower
further agrees to aid in the furnishing to the Authority or the Trustee of
opinions that may be required under the Indenture. The Borrower covenants and
agrees that the Trustee shall be entitled to and shall have all the rights,
including the right to enforce against the Borrower the provisions of the
Financing Documents, pertaining to the Trustee notwithstanding the fact that the
Trustee is not a party to the Financing Documents. The Borrower has also
reviewed the Indenture and the forms of the Bonds and the Borrower hereby
approves the forms of the Indenture and the Bonds.

            Section 6.7. Assignment of Agreement or Note. (A) The Borrower may
not assign its rights, interests or obligations hereunder or under the Note.

            (B) The Authority agrees that it will not assign or transfer any of
the Financing Documents or the revenues and other


                                      -37-
<PAGE>

receipts, funds and moneys to be received thereunder during the Term except to
the Trustee as provided in this Agreement and the Indenture.

            Section 6.8. Inspection. The Authority, the Trustee and their duly
authorized agents shall have (1) the right at all reasonable times upon
reasonable notice to enter upon and to examine and inspect the Project Realty
and the Project Equipment and (2) such rights of access thereto as may be
reasonably necessary for the proper maintenance and repair thereof in the event
of failure by the Borrower to perform its obligations under this Agreement. The
Authority and the Trustee shall also be permitted, at all reasonable times, to
examine the books and records of the Borrower with respect to the Project Realty
and the Project Equipment.

            Section 6.9. Default Notification. The Borrower shall deliver to the
Authority and the Trustee within ninety (90) days after the close of each Fiscal
Year, commencing with the first Fiscal Year ending following the Completion
Date, a certificate signed by an Authorized Representative of the Borrower to
the effect that the Borrower is in compliance with the provisions of the
Financing Documents or specifying the nature of the non-compliance and the steps
the Borrower is taking to correct any non-compliance.

            Section 6.10. Covenant Against Discrimination. (A) The Borrower in
the performance of this Agreement will not discriminate or permit discrimination
against any person or group of persons on the grounds of race, color, religion,
age, marital status, national origin, ancestry, sex, sexual orientation,
political beliefs, mental retardation, physical or learning disability, or
history of mental disorder, in any manner prohibited by the laws of the United
States or of the State of Connecticut.

            (B) The Borrower will comply with the provisions of the resolution
adopted by the Authority on June 14, 1977, as amended, and the policy of the
Authority implemented pursuant thereto concerning the promotion of equal
employment opportunity through affirmative action plans. The resolution requires
that all borrowers receiving financial assistance from the Authority adopt and
implement an affirmative action plan prior to the closing of the loan. The plan
shall be updated annually as long as the Bonds remain Outstanding.

            Section 6.11. Books and Records; Financial Statements and Other
Information. The Borrower covenants that it shall keep proper books of records
and accounts in which full, true and correct entries will be made of all
dealings or transactions of or in relation to the business and financial affairs
of the Borrower, in accordance with generally accepted accounting principles,
consistently applied. The Authority and the owner and their duly authorized
agents shall have the right at all reasonable times to


                                      -38-

examine and make copies of the books and records of the Borrower. The Borrower

      statements of the Borrower prepared in accordance with GAAP, which shall

      and (ii) a letter of the Vice President - Legal Affairs & Investor
      Relations of the Borrower to the effect that to the best of his or her

      Default hereunder, or otherwise describing any such event known to such
      officer, which letter shall include, in reasonable detail, the
      calculations demonstrating the compliance or non-compliance by the
      Borrower, as of the end of such Fiscal Year, with each applicable

      reflect all eliminations and adjustments (consisting only of normal
      recurring adjustments, except as noted in such letter) necessary for a
      fair presentation of the Borrower's financial position and results of
      operation for such quarter and the year to date, and (B) no event has
      occurred which constitutes or would, with the passage of time or the
      giving of notice or both, constitute an Event of Default hereunder, or
      otherwise describing any such event known to such officer, which letter
      shall include, in reasonable detail, the calculations demonstrating the
      compliance or non-compliance by the Borrower, as of the end of such

      any Event of Default or any Determination of Taxability or of any act,
      omission, thing or condition which upon the giving of notice or lapse of

      Determination of Taxability, which notice shall describe the Event of
      Default or Determination of Taxability or other act, omission, thing or
      condition in question and shall set forth in detail what action the

all applicable zoning, planning, building, environmental protection, sanitary,
safety and other laws, rules and regulations of governmental authorities having
jurisdiction over the Mortgaged Property, and the Borrower shall not permit a
nuisance thereon; but it shall not be a breach of this Section if the Borrower
fails to


                                      -43-
<PAGE>

comply with such laws, rules and regulations during any period in which the
Borrower shall in good faith be diligently contesting the validity thereof.
Subject to the foregoing, the Borrower may at its cost remodel or make
substitutions, modifications and improvements to the Mortgaged Property as it
deems desirable for its use and purposes and the same shall be the property of
the Borrower and be included as part of the Mortgaged Property and the Project.

            (B) The Borrower agrees that all repairs, renewals, replacements,
improvements, additions and extensions, extraordinary repairs, or property in
the nature thereof, which shall be made or acquired by the Borrower during the
term hereof in connection with the Mortgaged Property forthwith shall become
part of the Mortgaged Property. The Borrower agrees to execute such instruments
as may be requested, from time to time, by the Trustee to effect the foregoing.

            (C) The Borrower shall duly pay or cause to be paid all taxes and
governmental charges of any kind that may at any time be lawfully assessed or
levied against or with respect to the Mortgaged Property, all utility and other
charges incurred in the operation, maintenance, use, occupancy and upkeep of the
Mortgaged Property and all assessments and charges lawfully made by any
governmental body for public improvements that may be secured by a lien on the
Mortgaged Property. However, the Borrower may contest in good faith any such
items, assessments and other charges and, in such event, may permit the taxes,
assessments or other charges so contested to remain unpaid during any period,
including appeals, when the Borrower is in good faith contesting the same, so
long as adequate reserves have been established and enforcement of the contested
item is effectively stayed. In the event that the Borrower fails to pay any such
taxes, assessments or other charges (other than in connection with a contest
permitted by the preceding sentence), the Trustee may (but shall be under no
obligation to), upon such notice to the Borrower as is reasonable under the
circumstances, pay such amounts, and any amounts so advanced therefor by the
Trustee shall become an additional obligation of the Borrower secured by the
Financing Documents, which amounts, together with interest thereon at the prime
rate of the Trustee from the date thereof, the Borrower agrees and covenants to
pay.

            Section 6.19. Transfer or Release of Mortgaged Property. Except as
expressly permitted in this Section and except for Permitted Encumbrances, the
Borrower will not sell or transfer any part of the tangible real or personal
property included in the Mortgaged Property, except as permitted in Section
3.6(B) hereof, or create, incur, assume or permit to exist any encumbrance, lien
or charge of any kind on the Mortgaged Property.

            (A) If no Event of Default shall have happened and be continuing,
the Borrower may, from time to time:


                                      -44-
<PAGE>

            (1) grant Permitted Encumbrances with respect to any real or
      personal property included in the Mortgaged Property; or

            (2) release unnecessary existing easements, licenses, rights of way
      and other rights or privileges; or

            (3) lease or license the use of a part or parts of the Mortgaged
      Property to any person for use in performing services necessary or
      desirable for proper and economical operation and use of the Mortgaged
      Property; provided, that prior to entering into any lease or license the
      Borrower shall deliver to the Trustee an opinion of Bond Counsel that such
      lease or license will not adversely affect the exclusion from gross income
      for federal income tax purposes of interest on the Bonds; or

            (4) remove, sell or otherwise dispose of property which has been
      replaced in the ordinary course of its business; or

            (B) The Borrower covenants that the net proceeds of any sale or
other disposition made pursuant to paragraph (A)(6) or (A)(7) above shall be
applied to the replacement of the property, fixtures or equipment sold or
disposed of, or shall otherwise be reinvested in the Mortgaged Property.

            Section 6.20. Preservation of Tax-Exempt Status of Bonds.

            (A) The Borrower agrees that (i) the Project conforms to the
description contained in the Appendices hereto; (ii) it shall not take any
action or permit any circumstances within its control to arise or continue, if
such action or circumstances, or its expectation on the date of issue of the
Bonds, would cause the Bonds to be "arbitrage bonds" under the Code or cause the
interest paid by the Authority on the Bonds to be subject to Federal income tax
in the hands of the holders thereof; and (iii) it shall use its best efforts to
maintain the tax-exempt status of the Bonds.

                                   ARTICLE VII

                         EVENTS OF DEFAULT AND REMEDIES

            Section 7.1. Events of Default. Any one or more of the following
shall constitute an "Event of Default" hereunder:

            (1) Any representation or warranty made by the Borrower in the
      Financing Documents or any certificate, statement, data or information
      furnished by the Borrower in connection therewith or included by the
      Borrower in its application to the Authority for assistance proves at any
      time to have been incorrect when made in any material respect.

            (2) Failure by the Borrower to pay any amount that has become due
      and payable pursuant to the Financing Documents, subject to any applicable
      notice and cure provisions (if any) contained therein.

            (3) Failure by the Borrower to comply with the default notification
      provisions of Article VI hereof.

            (4) The occurrence of an "event of default" under Section 8.1 of the
      Indenture.

            (5) Failure by the Borrower to observe or perform any covenant,
      condition or agreement hereunder or under the Financing Documents (except
      those referred to above) continuance of such failure for a period of
      thirty days after receipt by the Borrower of written notice specifying the
      nature of such failure.

            (6) The Borrower shall (a) apply for or consent to the appointment
      of a receiver, trustee, liquidator or custodian or the like of itself or
      of its property, (b) admit in writing its inability to pay its debts
      generally as they become due, (c) make a general assignment for the
      benefit of creditors, (d) be adjudicated a bankrupt or insolvent, or (e)
      commence a voluntary case under the Federal bankruptcy laws of the United

      reorganization, an arrangement with creditors or an order for relief or
      seeking to take advantage of any insolvency law or file an answer
      admitting the material allegations of a petition filed against it in any
      bankruptcy, reorganization or insolvency proceeding; or corporate action
      shall be taken by it for the purpose of effecting any of the foregoing; or
      if without the application, approval or consent of the Borrower, a
      proceeding shall be instituted in any court of competent jurisdiction,
      seeking in respect of the Borrower an adjudication in bankruptcy,
      reorganization, dissolution, winding up, liquidation, a composition or
      arrangement with creditors, a readjustment of debts, the appointment of a
      trustee, receiver, liquidator or custodian or the like of the


                                      -46-
<PAGE>

      Borrower or of all or any substantial part of its assets, or other like
      relief in respect thereof under any bankruptcy or insolvency law, and, if
      such proceeding is being contested by the Borrower in good faith, the same
      shall continue undismissed, or pending and unstayed, for any period of 75
      consecutive days.

            (7) The occurrence of an event of default under the Credit Agreement
      as set forth in Section 6.1 of the Credit Agreement (the provisions of
      which are herein incorporated by reference and shall survive herein
      regardless of the payment of all other obligations issued under the Credit
      Agreement).

            Section 7.2. Remedies on Default. (A) Whenever any Event of Default
shall have occurred, the Trustee, or the Authority where so provided herein, may
take any one or more of the following actions:

            (1) The Trustee, as and to the extent provided in Article VIII of
      the Indenture, may cause all amounts payable under the Financing Documents
      to be immediately due and payable without notice or demand of any kind,
      whereupon the same shall become immediately due and payable.

            (2) The Authority, without the consent of the Trustee or any
      Bondholder, may proceed to enforce the obligations of the Borrower to the
      Authority, to the Trustee and to the appropriate taxing jurisdictions
      under Section 6.2 of this Agreement.

            (3) The Trustee may exercise any and all rights and remedies it may
      have under the Financing Documents.

            (4) The Trustee may take whatever action at law or in equity it may
      have to collect the amounts then due and thereafter to become due, or to
      enforce the performance or observance of the obligations, agreements, and
      covenants of the Borrower under the Financing Documents.

            (5) The Trustee may require the Borrower to obtain the prior written
      consent of the Trustee to the taking of any action otherwise permitted by
      the Financing Documents including, without limitation, the incurrence of
      any obligation or any transfer of Mortgaged Property.

            (B) In the event that any Event of Default or any proceeding taken
by the Authority (or by the Trustee on behalf of the Authority) thereon shall be
waived or determined adversely to the Authority, then the Event of Default shall
be annulled and the Authority and the Borrower shall be restored to their former
rights hereunder, but no such waiver or determination shall extend to any
subsequent or other default or impair any right consequent thereon.


                                      -47-
<PAGE>

            Section 7.3. Remedies on Public Purpose Default. (A) If the Borrower
shall default in the performance of any of its covenants contained in Section
6.4 hereof and such default shall constitute an Event of Default under Section
7.1 hereof, and such Event of Default shall continue for thirty (30) days
without the Trustee's or Bondowners' instituting the remedial steps provided for
in subsection 7.2(A)(1) hereof or subsection 8.1(B) of the Indenture, the
Authority may, so long as such Event of Default is continuing, send a notice to
the Trustee calling for the acceleration of all of the Borrower's obligations
under the Financing Documents and for the redemption of all of the Bonds then
Outstanding. Any such notice shall set forth in reasonable detail the default by
the Borrower giving rise thereto and shall specify the date upon which (1)
notice of Bond redemption is to be given by the Trustee (which shall be not less
than one hundred twenty days from the date of the Authority's determination
notice) and (2) the redemption of the Bonds is to occur (which shall be thirty
days after notice of redemption is given by the Trustee). Within thirty days
following receipt of the notice, the Trustee shall forward a copy thereof to the
Borrower and each registered Bondowner, together with a copy of Sections 6.4 and
7.3 of this Agreement.

            (B) If, within sixty days after the mailing of notice by the Trustee
to the Borrower and Bondowners, the Trustee receives no objection (as
hereinbelow provided) to such redemption, the Trustee shall give such notice and
effect to acceleration of the Borrower's obligations and the redemption of all
Outstanding Bonds in accordance with the Authority's notice and pursuant to
Section 2.4 of the Indenture. If, however, the Borrower or any Bondowner
disputes the existence of such Event of Default, the Borrower or such Bondowner
shall mail a notice to the Authority and the Trustee containing a statement of
such person's belief with respect to the claimed default. The receipt of such
notice by the Trustee shall serve to suspend the proceedings for redemption of
Bonds initiated by the Authority's notice of default.

            (C) If upon receipt of such notice from the Borrower or any
Bondowner, the Authority determines to affirm its earlier determination, either
the Borrower or any Bondowner shall have the right to bring an action in any
court of competent jurisdiction to enjoin the proceedings for the redemption of
the Bonds, and during the pendency of any such action the redemption proceedings
shall be suspended. Neither the Authority, the Borrower nor any Bondowner shall
be responsible for any costs, fees, expenses, or counsel fees incurred by any
other party in connection with any such action except that the Borrower shall be
responsible for the payment of the costs, fees and expenses of the Trustee and
its counsel. In the event the Authority is successful in such a proceeding, and
a final judgment is rendered which is not appealable or appealed within sixty
days thereafter finding the Borrower in default under Section 6.4 hereof, the
Trustee shall, promptly upon receipt of notice of the entry of the decision,
give notice of the redemption of all Outstanding Bonds under Section 6.4 of the
Indenture, and


                                      -48-
<PAGE>

redeem all such Bonds upon the date fixed for redemption in the notice (which
shall be thirty days after the notice is given). In the event the Borrower or
such Bondowners are successful in such a proceeding, and a final judgment is
rendered which is not appealable or appealed within sixty days thereafter
finding the Borrower not to be in default under Section 6.4 hereof, all
proceedings for the redemption of Bonds commenced under this Section shall be
terminated. No such judgment, however, shall prejudice the exercise of the
Authority's rights under this Section upon the occurrence of any subsequent
failure of performance under Section 6.4 hereof.

            (D) Within fifteen days of the date the Trustee gives notice of any
redemption of Bonds pursuant to this Section, the Borrower shall pay as a final
loan payment a sum sufficient, together with other funds on deposit with the
Trustee and available for such purpose, to redeem all Bonds then Outstanding
under the Indenture at 100% of the principal amount thereof plus accrued
interest to the redemption date. The Borrower shall also pay or provide for all
reasonable and necessary fees and expenses of the Trustee and any Paying Agent
accrued and to accrue through the date of redemption of all such Bonds.

            (E) Nothing contained in this Section shall be deemed to prevent the
Authority or the Borrower from seeking equitable relief if it asserts or
disputes, as the case may be, the existence of an event of a public purpose
default.

            Section 7.4. No Duty to Mitigate Damages. Unless otherwise required
by law, neither the Authority, the Trustee nor any Bondholder shall be obligated
to do any act whatsoever or exercise any diligence whatsoever to mitigate the
damages to the Borrower if an Event of Default shall occur.

            Section 7.5. Remedies Cumulative. No remedy herein conferred upon or
reserved to the Authority or the Trustee is intended to be exclusive of any
other available remedy or remedies but each and every such remedy shall be
cumulative and shall be in addition to every remedy given under this Agreement
or now or hereafter existing at law or in equity or by statute. Delay or
omission to exercise any right or power accruing upon any default or failure by
the Authority or the Trustee to insist upon the strict performance of any of the
covenants and agreements herein set forth or to exercise any rights or remedies
upon default by the Borrower hereunder shall not impair any such right or power
or be considered or taken as a waiver or relinquishment for the future of the
right to insist upon and to enforce, by injunction or other appropriate legal or
equitable remedy, strict compliance by the Borrower with all of the covenants
and conditions hereof, or of the right to exercise any such rights or remedies,
if such default by the Borrower be continued or repeated.

with the mandatory scheduled redemption provisions of Section 2.4 of the
Indenture.

                                 PROMISSORY NOTE

No. 1                                                                 $3,810,000

            Sonics & Materials, Inc., a corporation organized and existing under
the laws of the State of Delaware (the "Borrower"), for value received, hereby
promises to pay to the order of the Connecticut Development Authority (the
"Authority") the principal sum of $3,810,000, together with interest on the
unpaid principal balance thereof from the date hereof until fully and finally
paid, together with all taxes levied or assessed on this Note or the debt
evidenced hereby against the holder hereof. Subject to Section 3.1 of the
Agreement (as hereinafter defined), the Borrower shall make monthly payments of
interest, the size being one-sixth of the next interest payment due under the
Indenture and monthly payments of principal or Scheduled Installments, the size
being one-twelfth of the next such principal installment or Scheduled
Installment under the Indenture. This Note shall bear interest at the rate of
interest borne by the Initial Bonds referred to below.

            This Note has been executed under and pursuant to a Loan Agreement,
dated as of December 1, 1997, by and among the Authority and the Borrower (the
"Agreement") and is secured by an Open-End Mortgage, dated as of December 1,
1997, from the Borrower to the Authority and Brown Brothers Harriman & Co. (the
"Original Purchaser") on premises located in Newtown, Connecticut (the
"Mortgage") and by a Security Agreement, dated as of December 1, 1997, by and
among the Authority, the Borrower and the Original Purchaser (the "Security
Agreement"). This Note is issued to evidence the obligation of the Borrower
under the Agreement to repay the loan made by the Authority from the proceeds of
its $3,810,000 (Sonics & Materials, Inc. Project) 1997 Series (the "Initial
Bonds"), together with interest thereon and all other amounts, fees, penalties,
premiums, adjustments, expenses, counsel fees and other payments of any kind
required to be paid by the Borrower under the Agreement and the Mortgage and the
Security Agreement. The Agreement includes provision for mandatory and optional
prepayment of this Note as a whole or in part, and in such event the prepayment
shall be credited in inverse order of principal installments due. The Agreement
further provides for the payment of interest on this Note at other rates in
certain circumstances. Advances made pursuant to Section 6.2 of the Agreement
shall bear interest at Base Rate (as defined in the Indenture), plus 2%.

            The rate of interest on this Note shall be the Applicable Percentage
of the Base Rate, determined as of the opening of business on each Interest
Payment Date (or if such Interest Payment Date is not a Business Day, on the
next succeeding Business Day), except that from and after any Determination of
Taxability (as

defined in the Agreement), the rate of interest on this Bond shall be the
Taxable Rate.

            For such purpose, the following definitions shall apply:

            "Applicable Percentage" means seventy-five percent (75%); provided
that, so long as the Original Purchaser shall be the Owner of the Bond, the
Applicable Percentage may be adjusted by such owner (i) to offset any decrease
in net interest income allocable to the Bond due to a change in the portion of
its interest expense allocable to the Bond that is disallowed as a deduction
under Section 165 of the Code, or (ii) to reflect changes in federal marginal
tax rates which adversely affect the taxable equivalent yield of the Bond to
such owner. The Applicable Percentage shall be determined as of the opening of
business on each Interest Payment Date (or if such Interest Payment Date is not
a Business Day, on the next succeeding Business Day).

            "Base Rate" means the rate determined from time to time by Original
Purchaser as its "base rate."

            "Interest Payment Date" means the last day of each month, commencing
January 1, 1998, and continuing until the maturity date hereof.

            This Note shall bear interest on the overdue principal and, to the
extent permitted by law, on overdue interest at the Base Rate plus 2%.

            The Agreement, the Mortgage, the Security Agreement and this Note
(hereinafter, together with the Tax Regulatory Agreement, collectively referred
to as the "Financing Documents") have been assigned to Brown Brothers Harriman
Trust Company (the "Trustee") acting pursuant to an Indenture of Trust, dated as
of December 1, 1997 (the "Indenture"), between the Authority and the Trustee.
Such assignment is made as security for the payment of the Initial Bonds and any
Additional Bonds issued by the Authority pursuant to the Indenture.

            As provided in the Agreement and subject to the provisions thereof,
payments hereon are to be made at the principal office of Brown Brothers
Harriman Trust Company, New York, New York, or at the office designated for such
payment by any successor trustee in an amount which, together with other moneys
available therefor pursuant to the Indenture, will equal the amount payable as
principal or Redemption Price, if any, of and interest on the Initial Bonds
outstanding under the Indenture on such due date.

            The Borrower shall make payments on this Note on the dates and in
the amounts specified herein and in the Agreement and in addition shall make
such other payments as are required pursuant to the Financing Documents, the
Indenture and the Bonds. In the event of default, as defined in any of the
Financing Documents, the

principal of and interest on this Note may be declared immediately due and
payable as provided in the Agreement. Upon any such declaration the Borrower
shall pay all costs, disbursements, expenses and reasonable counsel fees of the
Authority and the Trustee in seeking to enforce their rights under any of the
Financing Documents.

            THE BORROWER ACKNOWLEDGES THAT THE LOAN EVIDENCED BY THIS NOTE IS A
COMMERCIAL TRANSACTION AND WAIVES ITS RIGHTS TO NOTICE AND HEARING AS ALLOWED
UNDER CHAPTER 903a OF THE CONNECTICUT GENERAL STATUTES, OR OTHERWISE UNDER ANY
STATE OR FEDERAL LAW WITH RESPECT TO ANY PREJUDGMENT REMEDY WHICH THE HOLDER
HEREOF MAY DESIRE TO USE. The Borrower further (1) waives diligence, demand,
presentment for payment, notice of nonpayment, protest and notice of protest,
notice of any renewals or extension of this Note, and all rights under any
statute of limitations, (2) agrees that the time for payment of this Note may be
changed and extended at the sole discretion of the Trustee without impairing its
liability hereon, and (3) consents to the release of all or any part of the
security for the payment thereof at the discretion of the Trustee or the release
of any party liable for this obligation without affecting the liability of the
other parties hereto. Any delay on the part of the Authority or the Trustee in
exercising any right hereunder shall not operate as a waiver of any such right,
and any waiver granted with respect to one default shall not operate as a waiver
in the event of any subsequent default.

            THIS INDENTURE OF TRUST, made and dated as of December 1, 1997, by
and between the Connecticut Development Authority, a body corporate and politic
constituting a public instrumentality and political subdivision of the State of
Connecticut (the "Authority"), and Brown Brothers Harriman Trust Company, a
limited purpose trust company organized under the laws of the State of New York,
with its principal office located in New York, New York, as Trustee.

                                WITNESSETH THAT:

            WHEREAS, the State Commerce Act, constituting Connecticut General
Statutes, Sections 32-1a through 32-23xx, as amended (the "Act"), declares that
there is a continuing need in the State (1) for industrial development and
activity to provide and maintain employment and tax revenues and to control,
abate and prevent pollution to protect the public health and safety, (2) for the
development of recreation facilities to promote tourism, provide and maintain
employment and tax revenues, and promote the public welfare, (3) for the
development of commercial and retail sales and service facilities in urban areas
to provide and maintain construction and permanent employment and tax revenues
to improve conditions of deteriorated physical development, slow economic growth
and eroded financial health of the public and private sectors in urban areas and
to revitalize the economy of urban areas, and (4) for assistance to public
service businesses providing transportation and utility services in the State,
and that the availability of financial assistance and suitable facilities are
important inducements to industrial and commercial enterprises to remain or
locate in the State and to provide industrial, recreation, urban and public
service projects; and

            WHEREAS, the Act provides that (1) the term "project" as used
therein means any facility, plant, works, system, building, structure, utility,
fixture or other real property improvement located in the State, and the land on
which it is located or which is reasonably necessary in connection therewith,
which is of a nature or which is to be used or occupied by any person for
purposes which would constitute it as an industrial project, recreation project,
urban project, public service project or health care project, and any real
property improvement reasonably related thereto, and (2) a project may also
include or consist exclusively of machinery, equipment or fixtures; and

            WHEREAS, the Act provides that the Authority shall have power to
determine the location and character of, and extend credit or make loans to any
person for the planning, designing, acquiring, improving and equipping of, a
project which may be secured by loan, lease or sale agreements, contracts and
other instruments upon such terms and conditions as the Authority shall
determine to be reasonable, to require the inclusion in any contract, loan
agreement or other instrument of such provisions for the construction, use,
operation, maintenance and financing of the

<PAGE>

project as the Authority may deem necessary or desirable, to enter into
agreements with prospective mortgagees and mortgagors, to issue its bonds for
such purposes, subject to the approval of the Treasurer of the State, and, as
security for the payment of the principal or redemption price, if any, of and
interest on any such bonds, to pledge or assign such a loan, lease or sale
agreement and the revenues and receipts derived by the Authority from such a
project; and

            WHEREAS, by resolution adopted June 18, 1997 in furtherance of the
purposes of the Act, the Authority has accepted the application of Sonics &
Materials, Inc. (the "Borrower") for assistance in the refinancing of certain
capital projects for the benefit of the Borrower and the acquisition and
installation therein of machinery and equipment related thereto, all to be used
for a manufacturing facility located in Town of Newtown, Connecticut; and

            WHEREAS, the Authority has by a resolution adopted November 19, 1997
authorized the issuance of $3,810,000 principal amount of its Industrial
Development Bonds (Sonics & Materials, Inc. Project ) 1997 Series (the "Initial
Bonds") for the purpose of refinancing the Bridge Loan Note which was used to
provide funds for the financing of certain capital projects for the benefit of
the Borrower, and paying necessary expenses incidental thereto, and financing
and refinancing certain additional capital projects for the benefit of the
Borrower; and

            WHEREAS, the Authority has determined that the issuance, sale and
delivery of the Initial Bonds, as hereinafter provided, is needed to refinance
the cost of the Project (as hereinafter defined), including necessary expenses
incidental thereto, and concurrently herewith the Authority and the Borrower
have entered into a Loan Agreement, dated as of December 1, 1997, providing for
a loan by the Authority to the Borrower for such purpose in an amount equal to
the principal amount of the Initial Bonds; and

            WHEREAS, additional funds may be necessary to repair, relocate,
rebuild or restore the Project following damage, destruction, taking or
condemnation thereof or to provide extensions, additions, improvements or
facilities to the Project and provision should therefore be made for the
issuance from time to time of additional bonds on a parity with the Initial
Bonds; and

            WHEREAS, the Initial Bonds and any Additional Bonds (as hereinafter
defined) shall be secured by the Mortgage and the Security Agreement (as such
terms are hereinafter defined); and

            WHEREAS, the Initial Bonds and any Additional Bonds shall be special
obligations of the Authority, payable solely out of the revenues and other
receipts, funds or moneys derived by the Authority under the Agreement (as
hereinafter defined), the Mortgage, the Security Agreement or the Indenture (as
hereinafter


                                       -2-
<PAGE>

defined) and from any amounts otherwise available under this Indenture for the
payment of the Initial Bonds; and

            WHEREAS, the Initial Bonds are to be originally issued as fully
registered bonds and such Bonds and the Trustee's certificate of authentication
to be endorsed thereon shall be in substantially the following form, with
appropriate variations, omissions and insertions as permitted or required by
this Indenture, to wit:

            CONNECTICUT DEVELOPMENT AUTHORITY (the "Authority"), a body
corporate and politic constituting a public instrumentality and political
subdivision of the State of Connecticut (the "State"), for value received,
hereby promises to pay to the Registered Owner identified above or registered
assigns on the maturity date set forth above, solely from the sources and in the
manner hereinafter provided, the principal sum set forth above, and in like
manner to pay interest on the unpaid principal balance thereof from the date
hereof until the Authority's obligation with respect to the payment of such sum
shall be discharged.

            The rate of interest on this Bond shall be the Applicable Percentage
of the Base Rate, determined as of the opening of business on each Interest
Payment Date (or if such Interest Payment Date is not a Business Day, on the
next succeeding Business Day), except that from and after any Determination of
Taxability (as defined in the Indenture), the rate of interest on this Bond
shall be the Taxable Rate.

      For such purpose, the following definitions shall apply:

      "Applicable Percentage" means seventy-five percent (75%); provided that,
so long as Brown Brothers Harriman & Co. shall be the Registered Owner of the
Bond, the Applicable Percentage may be adjusted by such Registered Owner (i) to
offset any decrease in net interest income allocable to the Bond due to a change
in the portion of its interest expense allocable to the Bond that is disallowed
as a deduction under Section 165 of the Code, or (ii) to


                                       -4-
<PAGE>

reflect changes in federal marginal tax rates which adversely affect the taxable
equivalent yield of the Bond to such Registered Owner. The Applicable Percentage
shall be determined as of the opening of business on each Interest Payment Date
(or if such Interest Payment Date is not a Business Day, on the next succeeding
Business Day).

      "Base Rate" means the rate determined from time to time by Brown Brothers
Harriman & Co. as its "base rate."

      "Interest Payment Date" means the first day of each month, commencing
January 1, 1998, and continuing until the maturity date hereof.

      "Registered Owner" means Brown Brothers Harriman & Co., its successors and
assigns and each other party who becomes a Registered Owner pursuant to Section
3.6 of the Indenture.

      "Taxable Rate" means the Base Rate plus 2%.

      Interest, calculated on the basis of a 360-day year for the actual number
of days elapsed, shall accrue daily in each interest period and shall be payable
monthly in arrears on each Interest Payment Date to the Registered Owner hereof,
as shown on the registration books of the Trustee on the Business Day preceding
such interest payment date (a "Record Date"). The interest due hereon shall be
calculated by the Original Purchaser in accordance with Section 2.3 of the
Indenture hereinafter described. Interest on this Bond shall be paid in such
manner as the Borrower and the Registered Owner shall agree.

      This Bond shall bear interest on the overdue principal and, to the extent
permitted by law, on overdue interest at the Taxable Rate.

            Payment of Principal and Interest. The principal or Redemption Price
of and interest on this Bond are payable at the corporate trust office of Brown
Brothers Harriman Trust Company, in New York, New York, as trustee (the
"Trustee"), or at the office designated for such payment of any successors as
paying agents, in any coin or currency of the United States of America, which,
on the respective dates of payment thereof, is legal tender for the payment of
public and private debts. As used herein, "Redemption Price", means, with
respect to a Bond, or a portion thereof, the principal amount of such Bond or
portion plus the applicable premium, if any, payable upon redemption pursuant to
the Indenture. Interest shall be payable by check or draft mailed or, if
requested by a Registered Owner of at least $1,000,000 aggregate principal
amount of Bonds, by wire transfer, to the Registered Owners of the Bonds as
shown on the registration books maintained by the Trustee in accordance with
Section 3.10 of the Indenture as of the close of business on the Record Date.
The "Regular Record Date" shall be the Business Day immediately preceding each
date on which interest


                                       -5-
<PAGE>

is to be paid, except for a Special Record Date. Any request for payment of
interest by wire transfer shall be delivered to the Trustee in writing not later
than the Regular or Special Record Date in respect of such interest payment. The
Bonds shall be issued in registered form in a single denomination equal to the
entire principal balance thereof. Notwithstanding the foregoing, so long as the
Original Purchaser is the registered owner of this Bond, the principal of and
the interest on this Bond shall be paid to the Original Purchaser as provided in
Section 2.3(F) of the Indenture.

            Defaulted Interest. Any interest on any Bond which is payable, but
is not punctually paid or provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the
Registered Owner on the relevant Record Date by virtue of having been such
Registered Owner, and such Defaulted Interest shall be paid to the Registered
Owner in whose name the Bond is registered at the close of business on a
"Special Record Date" to be fixed by the Trustee, such Special Record Date to be
not more than twenty (20) nor less than ten (10) days prior to the date of the
proposed payment. The Trustee shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed, first
class postage prepaid, to each Bondholder, at such Bondholder's address as it
appears on the registration books, not less than ten (10) days prior to such
Special Record Date but not more than thirty (30) days prior to the date of
proposed payment.

            Authorization and Purpose. This Bond is one of an authorized issue
of bonds of the Authority in the aggregate principal amount of $3,810,000
designated: Industrial Revenue Bonds (Sonics & Materials, Inc. - 1997 Series)
(the "Bonds") which are issued for the purpose of refinancing the Bridge Loan
Note which was issued for the purpose of financing certain capital projects for
the benefit of Sonics & Materials, Inc. (the "Borrower"), a corporation
organized and existing under the laws of the State of Delaware, and paying
necessary expenses incidental thereto, and financing and refinancing certain
additional capital projects for the benefit of the Borrower. The project
consists of certain capital projects, to be refinanced with the proceeds of the
Bonds, together with related facilities, and the acquisition and installation
therein of machinery and equipment related thereto, all to be used for
manufacturing purposes (collectively, the "Project"). The Bonds are issued
pursuant to the State Commerce Act, constituting Connecticut General Statutes,
Sections 32-1a through 32-23xx, as amended, a resolution adopted by the
Authority on November 19, 1997 and an Indenture of Trust, dated as of December
1, 1997 (which Indenture as from time to time amended and supplemented is herein
referred to as the "Indenture"), duly executed and delivered by the Authority to
the Trustee, and are equally and ratably secured by and entitled to the
protection of the Indenture, which is on file in the office of the Trustee.


                                       -6-
<PAGE>

            Pledge and Security. Pursuant to the Indenture, the Authority has
assigned to the Trustee all of its right, title and interest in and to a Loan
Agreement (the "Agreement"), dated as of December 1, 1997, between the Authority
and the Borrower, and the Note of the Borrower evidencing its obligations under
the Agreement (except for certain enforcement rights with respect to the Project
which are reserved in the Indenture), including all rights to receive loan
payments sufficient to pay the principal or Redemption Price, if any, of and
interest and all other amounts due on the Bonds as the same become due, to be
made by the Borrower pursuant to the Agreement. The Agreement sets forth the
terms and conditions under which the Authority will provide financing and
refinancing for the Project and under which the Borrower will use and occupy the
Project and make loan payments to the Authority in such amounts as are necessary
to pay the principal of, premium, if any, and interest on the Bonds. Reference
is hereby made to the Indenture for the definition of any capitalized word or
term used but not defined herein and for a description of the property pledged,
assigned and otherwise available for the payment of the Bonds, the provisions,
among others, with respect to the nature and extent of the security, the rights,
duties and obligations of the Authority, the Trustee and the holders of the
Bonds, and the terms upon which the Bonds are, and additional bonds on a parity
therewith may be, issued and secured and the holders of the Bonds are deemed to
assent to the provisions of the Indenture by the acceptance of this Bond. The
Bonds are also secured by a Mortgage with respect to the Project Realty and a
Security Agreement with respect to the Project Equipment.

            Additional Bonds. So long as the Financing Documents are in effect
and the Borrower shall not be in default thereunder, one or more series of
Additional Bonds on a parity with the Bonds may be authorized by resolution of
the Authority and thereupon authenticated and delivered upon original issuance
for the purposes and under the conditions stated in the Agreement and upon
compliance with the provisions of the Indenture with respect to the terms upon
which Additional Bonds may be issued and delivered.

            Optional Redemption. The Bond may be redeemed at the election of the
Authority at the written direction of the Borrower, in whole or in part (but if
in part in the principal amount of $100,000 or integral multiples of $5,000 in
excess thereof), on any Interest Payment Date, at a price equal to 100% of the
principal amount thereof to be redeemed, together with accrued interest to the
date of redemption (as defined in the Indenture). The Borrower shall provide the
Registered Owner with notice of the date of any optional redemption pursuant to
this paragraph and the principal amount of the Bond to be redeemed by
first-class mail, postage prepaid, sent at least fifteen (15) days before such
redemption date to the Registered Owner at the registered address of the
Registered Owner appearing on the registration books maintained pursuant to the
Indenture as of the close of business on the Business Day prior to such mailing.
On each such redemption date,


                                       -7-
<PAGE>

payment of the redemption price having been made to the Registered Owner as
provided herein and in the Indenture, the Bond or the portion thereof so called
for redemption shall become due and payable on the redemption date and interest
shall cease to accrue thereon from and after the redemption date.

            Optional Public Purpose Redemption. If the Borrower fails to perform
its obligations under the public purpose covenants contained in Section 6.4 of
the Agreement, the Bond shall be subject to redemption prior to maturity as a
whole at the option of the Authority in accordance with Section 7.3 of the
Agreement, at the Redemption Price of 100% of the principal amount thereof plus
accrued interest to the redemption date.

            Mandatory Scheduled Redemption. The Bond shall be redeemed in part
by the Authority in equal monthly installments of $16,710.52 on each Interest
Payment Date, commencing January 1, 1999, at a redemption price equal to 100% of
the principal amount thereof, without premium; provided, however, that the
Registered Owner and the Borrower, with notice to the Authority, may agree to a
different schedule of principal amortization, provided that (1) no such schedule
shall provide for the deferral of the payment of any principal beyond the final
maturity of the Bond, and (2) prior to the effectiveness of such schedule, there
shall be delivered to the Registered Owner an opinion of nationally recognized
bond counsel to the effect that the adoption of such schedule will not cause
interest on the Bond to no longer be excluded from gross income for Federal
income tax purposes.

            Mandatory Taxability Redemption. In the event of a Determination of
Taxability, the Bond shall be redeemed at the time and in the manner as provided
in the Indenture, at the Redemption Price applicable at the first optional
redemption date. If any Bonds are paid at maturity or purchased by the Borrower
or the Trustee or redeemed subsequent to a Tax Incidence Date without payment of
an amount at least equal to the amounts that would have been received if such
Bonds had been redeemed on the date of such retirement at the applicable
Redemption Price and otherwise in accordance with the provisions hereof, the
holders of such Bonds at the time of maturity, purchase or redemption, upon
establishing their then ownership thereof, shall be entitled to receive as an
additional premium thereon an amount equal to the difference between the amounts
actually received and the amounts that would have been received upon such
retirement of such Bond.

            Mandatory Redemption at Option of the Registered Owner of the Bond.
All or any portion of the Bond shall be redeemed by the Authority on or after
the 5th anniversary of date of original issuance of the Initial Bonds, at a
redemption price equal to 100% of the principal amount thereof plus accrued
interest to the date of redemption, upon the written demand, in the form
attached as an exhibit to this Bond, of the Registered Owner of the Bond, with a
copy to the Authority. The Bond, or any portion thereof, shall be


                                       -8-
<PAGE>

redeemed, and the redemption of the Bond shall be paid to the Registered Owner
of the Bond, on the date specified by the Registered Owner of the Bond.
Notwithstanding the foregoing, if the Registered Owner of the Bond shall demand
the redemption of the Bond in whole pursuant to this paragraph, the Borrower
shall have the right to purchase the Bond on any date after the date of the
Bondholder's written demand and prior to the next Business Day preceding the
date of the proposed redemption, at a purchase price equal to 100% of the
principal amount of the Bond, together with accrued interest to the date of
purchase.

            In the event of a redemption of this Bond in whole, the redemption
price shall be paid to the Registered Owner of this Bond only upon surrender of
this Bond at the principal office of the Borrower or such other place as the
Borrower shall designate on such Interest Payment Date. In the event of a
partial optional or mandatory redemption, payment shall be made by wire transfer
of immediately available funds without presentation and surrender of this Bond,
provided that the Borrower's record of such payment shall be conclusive and
binding upon such holder and each succeeding Owner of the Bond, absent manifest
error.

            Additional Amounts Payable on Redemption. Upon any whole or partial
redemption of the Bonds there shall also be due and payable, concurrently with
the payment of the Redemption Price, interest accrued on the Bonds to the date
of redemption and all other amounts then due under the Financing Documents.

            Redemption Procedures. If any of the Bonds are to be called for
redemption, other than an optional or mandatory scheduled redemption by the
Borrower, the Indenture requires a copy of the redemption notice to be mailed at
least thirty but not more than sixty days prior to such redemption date to the
registered owner of each Bond to be redeemed at the address shown on the
registration books. All Bonds so called for redemption will cease to bear
interest after the date fixed for redemption if funds for their redemption are
on deposit at the place of payment at that time.

            Amendment of Indenture. The Indenture permits, with certain
exceptions as therein provided, the amendment thereof and the modification of
the rights and obligations of the Authority and the rights of the holders of the
Bonds at any time by the Authority with the consent, in certain cases, of the
holders of not less than a majority in aggregate principal amount of each series
of the Bonds at the time outstanding thereunder. Any such consent shall be
conclusive and binding upon each such holder and upon all future holders of each
Bond and of any such Bond issued upon the transfer thereof, whether or not
notation of such consent is made thereon.

            Exchange of Bonds. The holder of this Bond may surrender the same,
at the corporate trust office of the Trustee, in exchange for an equal aggregate
principal amount of Bonds of any of the


                                       -9-
<PAGE>

authorized denominations of the same maturity and maturities as this bond or the
Bonds so surrendered, subject to the conditions and upon payment of the charges
provided in the Indenture.

            Transfer of Bonds. This Bond is transferable only upon the books of
the Authority kept for that purpose at the corporate trust office of the Trustee
by the registered owner hereof in person, or by his duly authorized attorney,
upon surrender of this bond (together with a written instrument of transfer
satisfactory to the Trustee duly executed by the registered owner or his duly
authorized attorney), and thereupon a new fully registered Bond in the same
aggregate principal amount shall be issued to the transferee in exchange
therefor as provided in the Indenture and upon payment of the charges therein
prescribed. The Authority, the Trustee and any Paying Agent may deem and treat
the person in whose name this bond is registered as the absolute owner hereof
for the purpose of receiving payment of, or on account of, the principal or
Redemption Price hereof and interest due hereon and for all other purposes
whatsoever.

            Limitation on Bondholder Enforcement Rights. The holder of this Bond
shall have no right to enforce the provisions of the Indenture, to institute an
action to enforce the provisions and covenants thereof or to institute, appear
in or defend any suit or other proceedings with respect thereto, except as
provided in the Indenture.

            Special Obligations of the Authority. This Bond and the issue of
which it forms a part are special obligations of the Authority, payable solely
out of the revenues or other receipts, funds or moneys of the Authority pledged
under the Indenture and from any amounts otherwise available under the Indenture
for the payment of the Bonds. Neither the State nor any municipality thereof
shall be obligated to pay the principal or Redemption Price, if any, of or
interest on this bond and neither the faith and credit nor taxing power of the
State or any municipality thereof is pledged to such payment. The Bonds do not
now and shall never constitute a debt or liability of the State or any
municipality thereof or bonds issued or guaranteed by either of them within the
meaning of any constitutional or statutory limitation.

            Estoppel Clause. This Bond is issued pursuant to and in full
compliance with the Constitution and laws of the State. It is hereby certified,
recited and declared that all acts, conditions and things required to exist,
happen and be performed precedent to and in the issuance of this Bond do exist,
have happened and have been performed in due time, form and manner as required
by law and that the issuance of this Bond and of the issue of which it forms a
part, together with all other obligations of the Authority, do not exceed or
violate any constitutional or statutory limitation.

            No Personal Liability. Neither the officers, directors or employees
of the Authority or the Trustee nor any person executing this Bond shall be
liable personally or be subject to any personal liability or accountability by
reason of the issuance hereof.

            Authentication by Trustee. This Bond shall not be valid or become
obligatory for any purpose or be entitled to any Security or benefit under the
Indenture until the certificate of authentication hereon shall have been signed
by the Trustee.

            (D) Subject to the provisions of subsection F below, the principal
or Redemption Price, if any, of and interest on the Initial Bond as they
respectively become due shall be payable at the corporate trust office of the
Trustee in New York, New York, or at the office designated for such payment of
any successor Paying Agent. Interest shall be payable by check or draft mailed
or, if requested by an owner of at least $1,000,000 aggregate principal amount
of Bonds, by wire transfer, to the registered owners of the Bonds as shown on
the registration books as of the close of business on the Record Date. Any
request for payment of interest by wire transfer shall be delivered to the
Trustee in writing not later than the Regular or Special Record Date in respect
of such interest payment.

            (E) Any interest on any Bond which is payable, but is not punctually
paid or provided for, on any Interest Payment Date (herein called "Defaulted
Interest") shall forthwith cease to be payable to the registered owner on the
relevant Record Date by virtue of having been such registered owner, and such
Defaulted Interest shall be paid to the registered owner in whose name the Bond
is registered at the close of business on a Special Record Date to be fixed by
the Trustee, such Special Record Date to be not more than twenty (20) nor less
than ten (10) days prior to the date


                                      -29-
<PAGE>

of proposed payment. The Trustee shall cause notice of the proposed payment of
such Defaulted Interest and the Special Record Date therefor to be mailed, first
class postage prepaid, to each Bondholder, at such Bondholder's address as it
appears on the registration books, not less than ten (10) days prior to such
Special Record Date but not more than thirty (30) days prior to the date of
proposed payment.

            (F) So long as the Original Purchaser shall be the owner of all of
the Initial Bonds Outstanding, and notwithstanding any other provisions of this
Indenture to the contrary, in accordance with the provisions of Section 3.4 of
the Loan Agreement, all payments by the Borrower of the loan payments under the
Loan Agreement attributable to the principal and Redemption Price of, and the
interest on, the Initial Bonds, shall be paid directly by the Borrower to the
Original Purchaser, and the Trustee shall have no responsibility with respect
to, and shall not be deemed to have any knowledge of, any Event of Default as a
result of any failure by the Borrower to make any payment described above
directly to the Original Purchaser, unless and until the Trustee shall have
received written notification from the Original Purchaser of such failure.

            Section 2.4. Redemption of Initial Bond. (A) Optional Redemption.
The Bond may be redeemed at the election of the Authority at the written
direction of the Borrower, in whole or in part (but if in part in the principal
amount of $100,000 or integral multiples of $5,000 in excess thereof), on any
Interest Payment Date, at a price equal to 100% of the principal amount thereof
to be redeemed, together with accrued interest to the date of redemption (as
defined in the Agreement). The Borrower shall provide the Bondholder with notice
of the date of any optional redemption pursuant to this paragraph and the
principal amount of the Bond to be redeemed by first-class mail, postage
prepaid, sent at least fifteen (15) days before such redemption date to the
Bondholder at the registered address of the Bondholder appearing on the
registration books maintained pursuant to this Agreement as of the close of
business on the Business Day prior to such mailing. On each such redemption
date, payment of the redemption price having been made to the Bondholder as
provided herein, the Bond or the portion thereof so called for redemption shall
become due and payable on the redemption date and interest shall cease to accrue
thereon from and after the redemption date.

            (B) Mandatory Scheduled Redemption. The Initial Bonds shall be
redeemed in part by the Authority in equal monthly installments on each Interest
Payment Date, commencing January 1, 1999, at a redemption price equal to 100% of
the principal amount thereof, without premium; provided, however, that the
Bondholder and the Borrower, with notice to the Authority, may agree to a
different schedule of principal amortization, provided that (1) no such schedule
shall provide for the deferral of the payment of any principal beyond the final
maturity of the Bond, and (2) prior to


                                      -30-
<PAGE>

the effectiveness of such schedule, there shall be delivered to the Bondholder
an opinion of nationally recognized bond counsel to the effect that the adoption
of such schedule will not cause interest on the Bond to no longer be excluded
from gross income for Federal income tax purposes.

            (C) Mandatory Taxability Redemption. In the event of a Determination
of Taxability, the Initial Bonds shall be redeemed at the time and in the manner
and as provided in this Indenture, at the Redemption Price applicable at the
first optional redemption date. If any Initial Bonds are paid at maturity,
purchased by the Borrower or the Trustee or redeemed subsequent to the Tax
Incidence Date without payment of an amount at least equal to the amounts that
would have been received if such Bonds had been redeemed on the date of such
retirement at the applicable Redemption Price set forth above, the holders of
such Bonds at the time of maturity, purchase or redemption, upon establishing
their then ownership thereof, shall be entitled to receive as an additional
payment thereon an amount equal to the difference between the amounts actually
received and the amounts that would have been received upon such retirement of
such Bonds. In the case of any redemption pursuant to this subsection, the
Authority or the Borrower shall deliver to the Trustee a certificate of an
Authorized Representative specifying the event giving rise to such inclusion in
the gross income of the recipient thereof and the dates which are the Tax
Incidence Date and the date of the Determination of Taxability. Such certificate
shall be delivered at least ten days before notice of redemption is required to
be given.

            (D) Mandatory Redemption at Option of the Bondholder. All or any
portion of the Initial Bonds shall be redeemed by the Issuer on or after the 5th
anniversary of date of original issuance, at a redemption price equal to 100% of
the principal amount thereof plus accrued interest to the date of redemption,
upon the written demand, in the form attached as an exhibit to the form of Bond,
of the Bondholder, with a copy to the Authority. The Initial Bond, or any
portion thereof, shall be redeemed, and the redemption of the Bond shall be paid
to the holder of the Bond, on the date specified by the Bondholder.
Notwithstanding the foregoing, if the Bondholder shall demand the redemption of
the Initial Bond in whole pursuant to this paragraph, the Borrower shall have
the right to purchase the Bond on any date after the date of the Bondholder's
written demand and prior to the next Business Day preceding the date of the
proposed redemption, at a purchase price equal to 100% of the principal amount
of the Bond, together with accrued interest to the date of purchase.

            (E) Optional Public Purpose Redemption. If the Borrower fails to
perform its obligations under Section 6.4 of the Agreement, the Initial Bonds
shall be subject to redemption prior to maturity as a whole at the option of the
Authority in accordance with Section 7.3 of the Agreement, at the Redemption
Price of 100%


                                      -31-
<PAGE>

of the principal amount thereof plus accrued interest to the redemption date.

            (F) Upon any redemption of Bonds there shall also be due and
payable, concurrently with the payment of the Redemption Price, interest accrued
on the Bonds and all other amounts then due under the Financing Documents.

            (G) Redemption of Initial Bonds permitted or required by this
Article II shall be made as follows, and the Trustee shall give the notice of
redemption referred to in Section 6.3 hereof in respect of each such redemption:

            (1) Redemption shall be made pursuant to the general optional
      redemption provisions of Section 2.4(A) on any Interest Payment Date and
      in such principal amounts as the Borrower shall request in a written
      notice to the Trustee in accordance with Section 8.2 of the Agreement.

            (2) Redemption shall be made pursuant to the mandatory scheduled
      redemption provisions of Section 2.4(C) as and when required by this
      Section without the necessity of any request by, or notification from the
      Authority or from the Borrower, but subject to the provisions of Section
      5.3 hereof.

            (3) Redemption shall be made pursuant to the Tax Incidence Date
      redemption provisions of Section 2.4(D) at the earliest possible date
      following receipt of the payments made by the Borrower prescribed in
      Section 6.3 of the Agreement, without the necessity of any instructions or
      further act of the Authority or the Borrower.

            (4) Redemption shall be made pursuant to the Authority's right of
      optional public purpose redemption under Section 2.4(E) upon the default
      of the Borrower under Section 6.4 of the Agreement at such time as the
      Authority shall request in a written notice to the Trustee in accordance
      with Section 7.3 of the Agreement.

            (H) Any Additional Bonds shall be subject to redemption prior to
maturity at such times and prices, in the manner and upon such terms and
conditions, not inconsistent with this Indenture, as shall be specified in the
Supplemental Indenture authorizing such Bonds.

            (I) Subject to the direct payment provisions of Section 2.3(F) above
and Section 3.4 of the Loan Agreement, all payments of the redemption price of
any of the Initial Bonds shall be made by the Trustee by wire transfer of
immediately available funds to the bank account designated by the Original
Purchaser in writing not less than two Business Days prior to the date of such
payment (or in the absence of such designation by check mailed to the Original
Purchaser at the address set forth in the Bond Register). Except


                                      -32-
<PAGE>

in the event of the redemption of the Initial Bonds in their entirety, any such
redemption shall be made without surrender of any of the Initial Bonds by the
Original Purchaser for payment, provided that the Trustee's records of such
payment shall be conclusive and binding on the Holder of the Initial Bonds,
absent manifest error.

            Section 2.5. Execution and Authentication of Bonds. (A) After their
authorization as provided in this Article, Bonds may be executed by or on behalf
of the Authority and delivered to the Trustee for authentication. Each Bond
shall be executed in the name of the Authority by the manual or facsimile
signature of any one or more Authorized Representatives of the Authority.

            (B) In case any officer who shall have signed any of the Bonds shall
cease to be such officer before the Bonds so signed shall have been
authenticated and delivered by the Trustee, such Bonds may nevertheless be
authenticated and delivered as herein provided as if the person who so signed
such Bonds had not ceased to be such officer. Any Bond may be signed on behalf
of the Authority by any person who, on the date of such act, shall hold the
proper office, notwithstanding that at the date of such Bond such person may not
have held such office.

            (C) The Bonds shall each bear thereon a certificate of
authentication, in the form set forth in the recitals to this Indenture,
executed manually by the Trustee. Only such Bonds as shall bear thereon such
certificate of authentication shall be entitled to any right or benefit under
this Indenture and no Bond shall be valid or obligatory for any purpose until
such certificate of authentication shall have been duly executed by the Trustee.
Such certificate of the Trustee upon any Bond executed on behalf of the
Authority shall be conclusive evidence that the Bond so authenticated has been
duly authenticated and delivered under this Indenture and that the holder
thereof is entitled to the benefits hereof.

            Section 2.6. Delivery of Bonds. The Initial Bonds and each series of
Additional Bonds shall be executed in the form and manner set forth herein and
shall be deposited with the Trustee and thereupon shall be authenticated by the
Trustee. Upon payment to the Trustee of the proceeds of sale thereof, such Bonds
shall be delivered by the Trustee to or upon the order of the purchasers
thereof, but only upon receipt by the Trustee of:

            (1) A certified copy of the Authority's resolution authorizing the
      issuance of such Bonds and, in the case of the Initial Bonds, the
      execution and delivery of this Indenture and the Financing Documents;

            (2) Original executed counterparts of the Financing Documents other
      than the Note, and the originally executed Note and, in the case of
      Additional Bonds, the supplement to


                                      -33-
<PAGE>

      or modification or amendment of the Agreement, this Indenture and the Note
      entered into prior to such delivery and such other documents as the
      Trustee or the purchaser of such Additional Bonds may require;

            (3) A request and authorization to the Trustee on behalf of the
      Authority to authenticate and deliver such Bonds to the purchasers therein
      identified upon payment to the Trustee, for the account of the Authority,
      of a sum specified in such request and authorization, plus any accrued
      interest on such Bonds to the date of such delivery. The proceeds of such
      payment shall be paid over to the Trustee and deposited in the Debt
      Service Fund, and the Project Fund pursuant to Article IV hereof; and

            (4) A written opinion by an attorney or firm of attorneys of
      recognized national standing on the subject of municipal bonds, to the
      effect that the issuance of such Bonds has been duly authorized and that
      all conditions precedent to the delivery thereof have been fulfilled and,
      in the case of any series of Additional Bonds, to the effect that the
      issuance of such Additional Bonds will not impair the exemption from
      federal income taxation of any Bonds Outstanding on the date of issuance
      of such Additional Bonds.

            Section 2.7. Issuance of Additional Bonds. (A) The Authority may
issue Additional Bonds hereunder from time to time on a parity with the Bonds
then Outstanding for any of the purposes listed below:

            (1) To pay the cost of completing the Project based on the original
      general design and scope of the Project set forth in the original plans
      and specifications therefor, with such changes as may have become
      necessary to carry out such original design, or to reimburse the Borrower
      for any such costs;

            (2) To pay the cost of refunding through redemption of any
      Outstanding Bonds issued under this Indenture and subject to such

      or permits, if applicable, required for occupancy or operation of the
      Project upon its completion;

Bonds, except in the case of Bonds delivered in any exchange or transfer
hereunder on or subsequent to the first Interest Payment Date of the Bond for
which it is exchanged or transferred, which shall be dated and bear interest
from the Interest Payment Date next preceding the date of such delivery, unless,
as shown by the records of the Trustee, interest on the Bond surrendered in
exchange for such Bond shall be in default, in which case such Bond shall be
dated as of the date to which interest has been paid in full on the Bond so
surrendered, and such Bond shall bear interest from such date.

            Section 3.2. Form and Denominations. The Initial Bonds shall be
issued in fully registered form, without coupons, in a single denomination equal
to the entire principal amount thereof. Any Additional Bonds shall be issued in
such form and denominations as shall be authorized in a Supplemental Indenture
providing for the issuance thereof. Subject to the provisions of Section 3.3

this Indenture, with such variations, omissions and insertions as are permitted
or required by this Indenture.

            Section 3.3. Legends. Each Bond shall contain on the face thereof a
statement to the effect that neither the State nor any municipality thereof
shall be obligated to pay the principal of the Bond or interest thereon and
neither the faith and credit nor taxing power of the State or any municipality
thereof is pledged to such payment. The Bonds may in addition contain or have
endorsed thereon such provisions, specifications and descriptive words not
inconsistent with the provisions of this Indenture as may be necessary or
desirable to comply with custom or otherwise as may be determined by the
Authority prior to the delivery thereof. Additional Bonds shall be lettered so
as to distinguish each series.

            Section 3.4. Medium of Payment. The principal or Redemption Price,
if any, of and interest on the Bonds shall be payable in any coin or currency of
the United States of America which, on the respective dates of payment thereof,

as to principal or Redemption price, if any, and interest at such place or
places as shall be specified, in the case of the Initial Bonds, in this
Indenture and, in the case of a series of Additional Bonds, in the Supplemental

Additional Bonds. All Initial Bonds, or Bonds of the same series of Additional
Bonds, maturing in any particular year shall bear interest at the same rate or
rates per annum.

            Section 3.6. Interchangeability, Transfer and Registry. (A) Each
Bond shall be transferable only upon compliance with the restrictions on

registered owner thereof in person or by his attorney duly authorized in
writing, upon presentation thereof together with a written instrument of
transfer satisfactory to the Trustee duly executed by the registered owner or
his duly authorized attorney. Upon the transfer of any Bond the Trustee shall
prepare and issue in the name of the transferee one or more new Bonds of the
same aggregate principal amount, series and maturity as the surrendered Bond.

            (B) Any Bond, upon surrender thereof at the corporate trust office
of the Trustee in New York, New York with a written instrument of transfer
satisfactory to the Trustee, duly executed by the registered owner or his
attorney duly authorized in writing, may, at the option of the owner thereof, be
exchanged for an equal aggregate principal amount of Bonds of the same series
and maturity of any other authorized denominations.

            (C) The Authority, the Borrower, the Trustee and any Paying Agent
may deem and treat the person in whose name any Bond shall be registered as the
absolute owner of such Bond, whether such Bond shall be overdue or not, for the
purpose of receiving payment of, or on account of, the principal and Redemption
Price, if any, of and interest on such Bond and for all other purposes, and all
payments made to any such registered owner or upon his order shall be valid and
effectual to satisfy and discharge the liability upon such Bond to the extent of
the sum or sums so paid, and neither the Authority, the Trustee nor any Paying
Agent shall be affected by any notice to the contrary.

            Section 3.7. Bonds Mutilated, Destroyed, Stolen or Lost. In case any
Bond shall become mutilated or be destroyed, stolen or lost, the Authority shall
execute and thereupon the Trustee shall authenticate and deliver, a new Bond of
like series, maturity and principal amount as the Bond so mutilated, destroyed,
stolen or lost, in exchange and substitution for such mutilated Bond, upon
surrender and cancellation of such mutilated Bond or in lieu of and substitution
for the Bond destroyed, stolen or lost, upon filing with the Trustee of evidence
satisfactory to the Authority and the Trustee that such Bond has been destroyed,
stolen or lost and proof


                                      -38-
<PAGE>

of ownership thereof, and upon furnishing the Authority and the Trustee with
indemnity satisfactory to them and complying with such other reasonable
requirements as the Authority and the Trustee may prescribe and paying such
expenses as the Authority and the Trustee may incur. All Bonds so surrendered to
the Trustee shall be cancelled by it. Any such new Bonds issued pursuant to this
Section in substitution for Bonds alleged to be destroyed, stolen or lost shall
constitute original additional contractual obligations on the part of the
Authority, whether or not the Bonds so alleged to be destroyed, stolen or lost
be at any time enforceable by anyone, and shall be equally secured by and
entitled to equal and proportionate benefits with all other Bonds issued
hereunder in any moneys or securities held by the Authority, the Trustee or any
Paying Agent for the benefit of the Bondholders.

            Section 3.8. Cancellation and Destruction of Bonds. All Bonds paid
or redeemed, either at or before maturity, shall be delivered to the Trustee
when such payment or redemption is made, and such Bonds together with all Bonds
purchased by the Trustee, shall thereupon be promptly cancelled. Bonds so
cancelled shall be cremated or otherwise destroyed by the Trustee, who shall
execute a certificate of cremation or destruction in duplicate under signature
of one of its authorized officers describing the Bonds so cremated or otherwise
destroyed, and one executed certificate shall be filed with the Authority and
the other executed certificate shall be retained by the Trustee.

            Section 3.9. Requirements With Respect To Transfers. In all cases in
which the privilege of transferring Bonds is exercised, the Authority shall
execute and the Trustee shall authenticate and deliver Bonds in accordance with
the provisions of this Indenture. All Bonds surrendered in any such transfer
shall forthwith be cancelled by the Trustee. For every such transfer of Bonds,
the Authority or the Trustee may, as a condition precedent to the privilege of
making such transfer, make a charge sufficient to reimburse it for any tax, fee
or other governmental charge required to be paid with respect to such transfer
and may charge a sum sufficient to pay the cost of preparing and delivering each
new Bond issued upon such transfer, which sum or sums shall be paid by the
person requesting such transfer. The Trustee shall not be required to transfer

<PAGE>

            (D) In making any such payment from the Project Fund the Trustee may
rely on such requisitions and proof delivered to it and the Trustee shall be
relieved of all liability with respect to making such payments in accordance
with the foregoing.

            (E) The Trustee shall hold in the Project Fund an amount equal to
five percent (5%) of the net proceeds of the Bonds until the Trustee has
received, with respect to the Bonds, a certified statement of Project Costs
together with the Borrower's certificate accompanied by an accountant's report
to the effect that Project Costs in an amount equal to 95% or more of the
Proceeds of the Bonds (as defined in the Tax Regulatory Agreement) have been
paid or incurred for the acquisition, construction or reconstruction of land or
depreciable property under the Code and have been or could be capitalized by the
Borrower for federal income tax purposes. Such documents may be delivered upon
issuance of the Bonds and may anticipate the use of the final amounts to be
requisitioned permitted by subsections 5.3(E) and (F) hereof. Upon the receipt
of such documents, the Trustee shall apply the balance in the Project Fund
(including any amounts deposited therein from the Earnings Fund calculated for
the Computation Period ending with the completion of the Project) to or at the
direction of the Borrower in accordance with such documents. The Borrower shall
notify the Trustee of any inability to deliver such documents, and in that event
the Trustee shall upon the receipt of such notification transfer the balance in
the Project Fund to the Redemption Account.

            (F) The completion of the Project shall be evidenced by the filing
with the Authority and the Trustee of a certificate of an Authorized
Representative of the Borrower in accordance with Article IV of the Agreement,
stating the date of such completion and the amount, if any, required in its
opinion for the payment of any remaining part of the costs of the Project. Upon
the filing of such certificate, the balance in the Project Fund in excess of the
amount, if any, stated in such certificate, shall be applied by the Trustee in
accordance with the written order of any Authorized Representative of the
Borrower in one or more of the following ways:

            (1) Deposited in the Redemption Account of the Debt Service Fund; or

            (2) Used in any other manner which preserves the exemption of
      interest on the Bonds from Federal income taxation, provided there is
      delivered to the Trustee an opinion of counsel by an attorney or firm of
      attorneys of recognized national standing on the subject of municipal
      bonds to the effect that the use of such moneys is permitted by law and
      will not adversely affect the exemption from federal income taxation of
      interest on the Bonds. The Trustee may rely on such opinion in any
      disbursement of funds pursuant to this subsection 5.2(F)(2).


                                      -43-

any balance in the Project Fund shall be deposited in the Redemption Account of
the Debt Service Fund.

            (G) Promptly following June 30 in each year following the issuance
of the applicable series of Bonds, until there is no balance remaining in the
Project Fund, the Borrower shall deliver a report to the Authority setting forth
the amount remaining in the Project Fund as of such date and a schedule of the
securities in which such amounts are invested (which shall be based upon reports
of the Trustee).

            (H) In the event the Borrower shall be required to or shall elect to
cause the Bonds to be redeemed in full pursuant to Article VIII of the
Agreement, the balance in the Project Fund which is not required to pay incurred
Project Costs shall be deposited in the Redemption Account of the Debt Service
Fund.

            (I) Notwithstanding anything herein to the contrary, upon and during
the continuance of any Event of Default, the Trustee shall not make any

separate accounts within the Debt Service Fund to be respectively designated
"Principal and Interest Account" and "Redemption Account".

            (B) The Trustee shall promptly deposit the following receipts in the
Debt Service Fund:

            (1) Any amount required pursuant to Section 4.1 hereof to be
      deposited from the proceeds of the Bonds, which shall be credited to the
      Principal and Interest Account.

      the Agreement, which shall be credited to the Principal and Interest
      Account, in the manner set forth in this Indenture and the Agreement, and
      applied together with amounts available in the Principal and Interest
      Account, to pay (i) the interest due on the Outstanding Bonds on the
      Interest Payment Date next succeeding such payment and (ii) the principal,
      if any, of the Outstanding Bonds due (otherwise than by call for
      redemption) on such interest payment date.

            (3) Excess or remaining amounts in the Project Fund required to be
      deposited in the Redemption Account of the Debt Service Fund pursuant to

                                      -44-
<PAGE>

            (4) Any other amounts required to be paid to the Debt Service Fund
      for payment of principal and interest due on the Bonds, which shall be
      credited to the Principal and Interest Account.

            (5) Prepayments under the Agreement received by the Trustee pursuant
      to Article VIII thereof, which shall be credited to the Redemption
      Account.

            (6) All other receipts when and if required by the Financing
      Documents or any subsequent agreement or by this Indenture to be paid into
      the Debt Service Fund, which shall be credited to the Principal and
      Interest Account.

            (C) There shall be paid from the Principal and Interest Account to
the respective Paying Agents on each Interest Payment Date for the Bonds the
amounts required for the payment of the principal and interest due on the Bonds
on such date. Such amounts shall be applied by the Paying Agents to the payment
of principal and interest on the Bonds when due. All other amounts payable on
the Bonds from the Principal and Interest Account shall be paid to the
respective Paying Agents upon receipt, and shall promptly be paid by such Paying
Agents to the Bondholders.

            (D) There shall be paid from the Principal and Interest Account to
the Paying Agents on each Interest Payment Date for the Bonds in immediately
available funds the amounts required for the payment of the Redemption Price.

            (E) Amounts in the Redemption Account shall be applied, as promptly
as practicable, to the purchase of Bonds at prices not exceeding the Redemption
Price thereof applicable on the next redemption date plus accrued interest and
all other amounts then due under the Financing Documents in connection with such
redemption. Such redemption date shall be the earliest date upon which Bonds are
subject to redemption from such amounts. Any amount in the Redemption Account
not so applied to the purchase of Bonds by forty-five days prior to the next
date on which the Bonds are so redeemable shall be applied to the redemption of
Bonds on such redemption date; provided that if such amount aggregates less than
$10,000, it need not be then applied to such redemption. The Bonds to be
purchased or redeemed shall be selected by the Trustee in the manner provided in
Section 6.2 hereof. Amounts in the Redemption Account to be applied to the
redemption of Bonds shall be paid to the respective Paying Agents on or before
the redemption date and applied by them on such redemption date to the payment
of the Redemption Price of the Bonds being redeemed plus interest on such Bonds
accrued to the redemption date and all other amounts then due under the
Financing Documents in connection with such redemption.

            (F) The Authority shall receive a credit in respect of the Scheduled
Payment for any Bonds which have been delivered by


                                      -45-
<PAGE>

the Authority or the Borrower to the Trustee and for any Bonds which prior to
such date have been purchased or redeemed and cancelled by the Trustee.

            (G) Any amounts remaining in the Debt Service Fund after payment in
full of the Bonds, the fees, charges and expenses of the Trustee and any Paying
Agent and all other amounts required to be paid hereunder or under the Financing
Documents shall be paid to the Borrower upon the expiration or sooner
termination of the Term of the Agreement.

            (B) On the first Business Day following each Computation Period, the
Trustee, upon written instructions of an Authorized Representative of the
Borrower, shall withdraw from the Earnings Fund and deposit to the Rebate Fund

by the Borrower pursuant to Section 3.11 of the Rebate Memorandum attached as an
exhibit to the Tax Regulatory Agreement. Computations of the amounts on deposit
in each Fund and of the Rebate Amount shall be furnished to the Trustee by the
Borrower in accordance with Section 4.5 of the Rebate Memorandum attached as an

            (C) Any amounts on deposit in the Earnings Fund following the

pay to the United States out of amounts in the Rebate Fund (1) not later than 30
days after the end of each five-year period following the date of issuance of
the Bonds of each series, an amount such that, together with amounts previously
paid, the total amount paid to the United States is equal to 90% of the Rebate
Amount calculated as of the end of the most recent Computation Period, and (2)
not later than 30 days after the date on which all of the Bonds of any series
have been paid or redeemed, 100% of the Rebate Amount as of the end of the


                                      -46-

final Computation Period. Absent such instructions, the Trustee shall pay all

then permitted by law, be invested in Authorized Investments. Investments
authorized under this Section shall be made by the Trustee at the written
request of an Authorized Representative of the Borrower, and may be made by the
Trustee through its own bond department. Any investment hereunder shall be made
in accordance with written instructions of the Borrower. Such investments shall
mature in such amounts and at such times as may be necessary to provide funds
when needed to make payments from such Funds or Accounts.

      yields in accordance with the Tax Regulatory Agreement is shown in a
      certificate of the Borrower delivered to the Trustee stating that the
      requirements of this paragraph (3) are satisfied in accordance with the
      Tax Regulatory Agreement, which shall be credited to the Fund or Account

      Service Reserve Fund in excess of the Debt Service Reserve Fund
      Requirement shall be transferred to the Debt Service Fund.

not be presented for payment when the principal thereof becomes due, either at
maturity, or at the date fixed for redemption thereof, or otherwise, and funds

                                      -47-

be the duty of the Trustee to pay such funds to the person or persons entitled
thereto in the case of a fully registered bond or if the person is not known to
the Trustee, to hold such funds, without liability for interest thereon, for the
benefit of the holder of such Bond, who shall thereafter be restricted
exclusively to such funds, for any claim of whatever nature on his part under
this Indenture or on, or with respect to, such Bond. Subject to applicable
escheat laws, funds remaining with the Trustee as above and unclaimed for six

                               REDEMPTION OF BONDS

            Section 6.1. Privilege of Redemption and Redemption Price. Bonds or
portions thereof subject to redemption prior to maturity shall be redeemable,
upon mailed notice as provided in this Article, at the times, at the Redemption
Prices and upon such terms in addition to and consistent with the terms
contained in this Article as shall be specified in Sections 2.3 and 2.4 hereof
and in such Bonds.

            Section 6.2. Selection of Bonds to be Redeemed. In the event of
redemption of less than all the Outstanding Bonds of like series and maturity,
the Trustee shall assign to each such Outstanding Bond a distinctive number for
each $25,000 in principal amount thereof, and shall select by lot, using such
method of selection as it shall deem proper in its discretion, from the numbers
assigned to such Bonds as many numbers as, at $25,000 for each number, shall
equal the principal amount of such Bonds to be redeemed. The Bonds to be
redeemed shall be Bonds to which are assigned numbers so selected, but only so
much of the principal amount of such Bond of a denomination of more than $25,000
shall be redeemed as shall equal $25,000 for each number assigned to it and so
selected. For purposes of this Section, Bonds which have theretofore been
selected by lot for redemption shall not be deemed Outstanding. Notwithstanding
the foregoing, redemption of the Initial Bonds shall be effected in accordance
with Section 2.4(I) hereof.

            Notwithstanding the foregoing, redemption of the Initial Bonds shall
be effected on accordingly with Section 2.4(I) hereof.

            Section 6.3. Notice of Redemption. When redemption is required by
this Indenture, the Trustee shall give notice of such redemption in the name of
the Authority, specifying the subsection of Section 2.4 hereof under which the
redemption is to be made, the series, maturities, numbers and amounts of the
Bonds or portions thereof to be redeemed, the redemption date and the place or
places where amounts due upon such redemption will be payable. Such notice shall
further state that on such date there shall become due and payable upon each
Bond or portion thereof to be redeemed the Redemption Price thereof together
with interest accrued to the redemption date and all other amounts then due
under the Financing Documents, and that from and after such date interest
thereon shall cease to accrue and be payable. Notice of redemption shall be
given by the Trustee in the name and on behalf of the Authority by mailing a
copy of each such notice to the registered owner of each Bond by first-class
mail postage prepaid, addressed to him at his last known address as it appears
upon the bond register, not more than 60 nor less than 30 days prior to the date
fixed for redemption. Such notice shall be effective when mailed and any failure
to receive such notice shall not affect the validity of the


                                      -49-
<PAGE>

proceedings for redemption. In the event of a postal strike, the Trustee shall
give notice by other appropriate means selected by the Trustee in its
discretion.

            Section 6.4. Payment of Redeemed Bonds. (A) Notice having been given
in the manner provided in Section 6.3 hereof, the Bonds or portions thereof so
called for redemption shall become due and payable on the redemption dates so
designated at the Redemption Price, plus interest accrued to the redemption date
and all other amounts then due under the Financing Documents. If, on the
redemption date, moneys for the redemption of all the Bonds or portions thereof
to be redeemed, together with interest to the redemption date, and all other
amounts then due under the Financing Documents, shall be held by the Paying
Agents so as to be available therefor on such date and if notice of redemption
shall have been given as aforesuch, then, from and after the redemption date,
interest on the Bonds or portions thereof so called for redemption shall cease
to accrue and become payable. If such moneys shall not be so available on the
redemption date, such Bonds or portions thereof shall continue to bear interest
until paid at the same rate as they would have borne had they not been called
for redemption.

            (B) Payment of the Redemption Price together with interest and all
other amounts then due to the Bondholder under the Financing Documents shall be
made to or upon the order of the registered owner, only upon presentation of the
Bond for cancellation or notation as provided in Section 6.5 hereof.

            Section 6.5. Cancellation of Redeemed Bonds. (A) All Bonds redeemed
in full under the provisions of this Article shall forthwith be cancelled and
destroyed by the Trustee and a certificate of destruction furnished to the
Authority, and no Bonds shall be executed, authenticated, issued or delivered in
exchange or substitution therefor or for or in respect of any paid portion of a
fully registered Bond.

            (B) If there shall be drawn for redemption less than all of a Bond,
the Authority shall execute and the Trustee shall authenticate and deliver, upon
the surrender of such Bond, without charge to the owner thereof, for the
unredeemed balance of the principal amount of the Bond so surrendered, Bonds of
like series and maturity in any of the authorized denominations.

                             REMEDIES OF BONDHOLDERS

            Section 8.1. Events of Default; Acceleration of Due Dates. (A) Each
of the following events is hereby defined as and shall constitute an "event of
default":

            (1) Failure to duly and punctually pay (a) the interest, (b) any
      installment of the principal or Redemption Price of any Bond, whether at
      the stated maturity thereof or upon proceedings for redemption thereof, or
      (c) any other amount due under the Financing Documents.

            (2) Failure to perform or observe any other of the covenants,
      agreements or conditions on the part of the Authority in this Indenture or
      in the Bonds contained and not otherwise a default hereunder and the
      continuance thereof for a period of thirty days after written notice given
      by the Trustee or by the holders of not less than 25% of the principal
      amount of Bonds then Outstanding.

            (3) The occurrence of an event of default under any of the Financing
      Documents.

            (B) Upon the happening and continuance of any event of default
specified in subsection 8.1(A) hereof, unless the principal of all the Bonds
shall have already become due and payable, either the Trustee (by notice in
writing to the Authority) or the holders of not less than 25% in principal
amount of the Bonds Outstanding (by notice in writing to the Authority and the
Trustee) may declare the principal or Redemption Price, if any, of all the Bonds
then Outstanding, and the interest accrued thereon, to be due and payable
immediately, and upon such declaration the same shall become and be immediately
due and payable, anything in this Indenture or in any of the Bonds contained to
the contrary notwithstanding.

            (C) The right of the Trustee or of the holders of not less than 25%
in principal amount of the Bonds to make any declaration authorized under
subsection 8.1(B) hereof with respect to any failure under subsection 8.1(A)(1)
hereof, however, is subject to the condition that if, at any time before such
declaration, all overdue installments of interest upon the Bonds and the
principal of all Bonds which shall have matured by their terms, together with
the reasonable and proper charges, expenses and liabilities of the Trustee,
shall either be paid by or for account of the Authority or provision
satisfactory to the Trustee shall be made for such payment, then in every such
case any such default and its consequences shall ipso facto be deemed to be
annulled, but no such annulment shall extend to or affect any subsequent default
or impair or exhaust any right or power consequent thereon.


                                      -54-
<PAGE>

            Section 8.2. Foreclosure and Enforcement of Remedies. (A) Upon the
happening and continuance, of any event of default, then and in every case the
Trustee may proceed, and upon the written request of the holders of not less
than 25% in the principal amount of the Bonds Outstanding shall proceed, to
protect and enforce its rights and the rights of the Bondholders under the Act,
the Bonds, the Financing Documents and this Indenture, and under any agreement
executed in connection with the foregoing, forthwith by such suits, actions or
special proceedings in equity or at law, or by proceedings in the office of any
board or officer having jurisdiction, whether for the specific performance of
any covenant or agreement contained in this Indenture or in aid of the execution
of any power granted therein or in the Act or for the enforcement of any legal
or equitable rights or remedies as the Trustee, being advised by counsel, shall
deem most effectual to protect and enforce such rights or to perform any of its
duties under this Indenture.

            (B) In the enforcement of any right or remedy under this Indenture
or under the Act, the Trustee shall be entitled to sue for, enforce payment on
and receive any or all amounts then or during any default becoming, and any time
remaining, due from the Authority for principal, Redemption Price, interest or
otherwise under any of the provisions of the Financing Documents, this Indenture
or of the Bonds, and unpaid, with interest on overdue payments at the applicable
rate or rates of interest specified in the Bonds, together with any and all
costs and expenses of collection and of all proceedings under the Financing
Documents, this Indenture and under the Bonds, without prejudice to any other
right or remedy of the Trustee or of the Bondholders, and to recover and enforce
any judgment or decree against the Authority, but solely as provided in the
Financing Documents, this Indenture and in the Bonds, for any portion of such
amounts remaining unpaid, with interest, costs, and expenses, and to collect in
any manner provided by law, the moneys adjudged or decreed to be payable.

            (C) Regardless of the happening of an event of default, the Trustee,
if requested in writing by the holders of not less than 25% in principal amount
of the Bonds then Outstanding and furnished with reasonable security and
indemnity, shall institute and maintain such suits and proceedings as it may be
advised shall be necessary or expedient to prevent any impairment of the
security under this Indenture by any acts which may be unlawful or in violation
of the Indenture or of any resolution authorizing Bonds, and such suits and
proceedings as the Trustee may be advised shall be necessary or expedient to
preserve or protect its interests and the interests of the Bondholders; but no
such request shall be otherwise than in accordance with the provisions of law
and of the Indenture or be unduly prejudicial to the interests of the holders of
Bonds not making such request.

            Section 8.3. Application of Revenues and Other Moneys After Default.
(A) All moneys received by the Trustee pursuant to


                                      -55-
<PAGE>

any right given or action taken under the provisions of this Article, after
payment of the costs and expenses of the proceedings resulting in the collection
of such moneys and of the expenses liabilities and advances incurred or made by
the Trustee, shall be deposited in the applicable account of the Debt Service
Fund and all moneys so deposited in such Fund and available for payment of the
Bonds shall be applied as follows:

            (1) Unless the principal of all of the Bonds shall have become or
      have been declared due and payable:

            FIRST To the payment of all amounts due under the Financing
            Documents, exclusive of unpaid principal and interest on the Note;

            SECOND To the payment to the persons entitled thereto of all
            installments of interest then due on the Bonds, in the order of the
            maturity of the installments of such interest and, if the amount
            available shall not be sufficient to pay in full any particular
            installment, then to the payment ratably, according to the amounts
            due on such installment, to the persons entitled thereto, without
            any discrimination or preference; and

            THIRD To the payment to the persons entitled thereto of the unpaid
            principal or Redemption Price, if any, of any of the Bonds or
            principal installments which shall have become due (other than Bonds
            called for redemption for the payment of which moneys are held
            pursuant to the provisions of this Indenture), in inverse order of
            maturity, from the respective dates upon which they become due and,
            if the amount available shall not be sufficient to pay in full Bonds
            or principal installments due on any particular date, then to the
            payment ratably, according to the amount of principal due on such
            date, to the persons entitled thereto without any discrimination or
            preference.

            (2) If the principal of all the Bonds shall have become or have been
      declared due and payable, to the payment of the principal and interest (at
      the rate or rates expressed thereon) then due and unpaid upon the Bonds
      without preference or priority of principal over interest or of interest
      over principal, or of any installment of interest over any other
      installment of interest, or of any Bond over any other Bond, ratably,
      according to the amounts due respectively for principal and interest, to
      the persons entitled thereto without any discrimination or preference.

            (B) Whenever moneys are to be applied pursuant to the provisions of
this Section, such moneys shall be applied at such times, and from time to time,
as the Trustee shall determine, having due regard to the amount of such moneys
available for


                                      -56-
<PAGE>

application and the likelihood of additional moneys becoming available for such
application in the future. Whenever the Trustee shall apply such funds, it shall
fix the date upon which such application shall be made. The Trustee shall give
such notice as it may deem appropriate of the deposit with it of any such moneys
and of the fixing of any such date, and shall not be required to make payment to
the holder of any Bonds until such Bonds shall be presented to the Trustee for
appropriate endorsement or for cancellation if fully paid.

            (C) Whenever all Bonds and interest thereon and all other amounts
due under the Financing Documents have been paid under the provisions of this
Section and all fees, expenses and charges of the Trustee and Paying Agents have
been paid, any balance remaining in the Debt Service Fund shall be paid to or
upon the order of the Borrower.

            Section 8.4. Actions by Trustee. All rights of action under this
Indenture or under any of the Bonds may be enforced by the Trustee without the
possession of any of the Bonds or the production thereof in any trial or other
proceedings relating thereto and any such suit or proceedings instituted by the
Trustee shall be brought in its name as Trustee without the necessity of joining
as plaintiffs or defendants any holders of the Bonds, and any recovery of
judgment, subject to the provisions of Section 8.3 hereof, shall be for the
benefit of the holders of the Outstanding Bonds.

            Section 8.5. Majority Bondholders Control Proceedings. The holders
of a majority in aggregate principal amount of Bonds then Outstanding shall have
the right, at any time, by an instrument or instruments in writing executed and
delivered to the Trustee, to direct the method and place of conducting all
proceedings to be taken in connection with the enforcement of the terms and
conditions of the Indenture, or for any other proceedings hereunder; but such
direction shall not be otherwise than in accordance with the provisions of law
and of the Indenture.

            Section 8.6. Individual Bondholder Action Restricted. (A) No holder
of the Bonds shall have any right to institute any suit, action or proceeding at
law or in equity for the enforcement of any provision of this Indenture or the
execution of any trust under this Indenture or for any remedy under this
Indenture, unless such holder shall have previously given to the Trustee written
notice of the happening of an event of default, as provided in this Article, and
the holders of at least 25% in principal amount of the Bonds then Outstanding
shall have filed a written request with the Trustee, and shall have offered it
reasonable opportunity, either to exercise the powers granted in this Indenture
or by the Act or by the laws of the State or to institute such action, suit or
proceeding in its own name, and unless such holders shall have offered to the
Trustee adequate security and indemnity against the costs, expenses and
liabilities to be incurred therein or thereby,


                                      -57-
<PAGE>

and the Trustee shall have refused to comply with such request for a period of
sixty days after receipt by it of such notice, request and offer of indemnity,
it being understood and intended that no holder of any Bond shall have any right
in any manner whatever by his or their action to affect, disturb or prejudice
the pledge created by the Indenture, or to enforce any right under the
Indenture, except in the manner therein provided; and that all proceedings at
law or in equity to enforce any provision of the Indenture shall be instituted,
had and maintained in the manner provided in the Indenture and for the equal
benefit of all holders of the Outstanding Bonds.

            (B) Nothing herein or in the Bonds contained shall affect or impair
the right of any Bondholder to payment of the principal or Redemption Price, if
any, of and interest on any Bond or other amounts due under the Financing
Documents at and after the maturity thereof, or the obligation of the Authority
to pay the principal or Redemption Price, if applicable, of and interest on each
of the Bonds or other amounts due under the Financing Documents to the
respective holders thereof at the time, place, from the source and in the manner
herein and in such Bonds expressed.

            Section 8.7. Effect of Discontinuance of Proceedings. In case any
proceeding taken by the Trustee on account of any event of default shall have
been dismissed, discontinued or abandoned for any reason, or shall have been
determined adversely, then and in every such case the Authority, the Trustee,
and the Bondholders shall be restored, respectively, to their former positions
and rights hereunder, and all rights, remedies, powers and duties of the Trustee
shall continue as though no such proceedings had been taken.

            Section 8.8. Remedies Not Exclusive. No remedy by the terms of this
Indenture conferred upon or reserved to the Trustee or to the holders of the
Bonds is intended to be exclusive of any other remedy, and each and every such
remedy shall be cumulative and shall be in addition to any other remedy given
hereunder or now or hereafter existing at law or in equity or by statute.

            Section 8.9. Delay or Omission Upon Default. No delay or omission of
the Trustee or of the holder of any Bond to exercise any right or power arising
upon any event of default shall impair any right or power or shall be construed
to be a waiver of any such default or any acquiescence therein; and every power
and remedy given by this Article to the Trustee and the holder of any Bond,
respectively, may be exercised from time to time and as often as may be deemed
expedient by the Trustee or by the Bondholders.

            Section 8.10. Notice of Default. The Trustee shall promptly mail to
each Bondholder written notice of the occurrence of any event of default of
which it has actual knowledge. The Trustee shall not, however, be subject to any
liability to any


                                      -58-
<PAGE>

Bondholder by reason of its failure to mail any notice required by this Section.
The Trustee shall not be deemed to have actual knowledge of any event of default
(other than a default specified in subsections 8.1(A)(l)(a) or (b)) unless it
shall be notified in writing thereof by the Borrower, the Authority, or the
holders of 25% in aggregate principal amount of the Bonds Outstanding.

            Section 8.11. Waivers of Default. The Trustee shall waive any event
of default hereunder and its consequences upon the written request of the
holders of one-half in aggregate principal amount of each series of the Bonds
then Outstanding; except that there shall not be waived without the consent of
the holders of all the Bonds Outstanding (a) any default in the payment of the
principal or Redemption Price of any Outstanding Bonds at the date of maturity
specified therein or (b) any default in the payment when due of the interest on
any such Bonds unless, prior to such waiver, all arrears of interest, with
interest (to the extent permitted by law) at the rate borne by the Bonds on
overdue installments of interest in respect of which such default shall have
occurred or all arrears of payments of principal when due, as the case may be,
and all expenses of the Trustee in connection with such default shall have been
paid or provided for, and in case of any such waiver, or in case any proceeding
taken by the Trustee on account of any such default shall have been dismissed,
discontinued or abandoned or determined adversely, then and in every such case
the Authority, the Trustee and the Bondholders shall be restored to their former
positions and rights hereunder respectively, but no such waiver, dismissal,
discontinuance, abandonment or determination shall extend to any subsequent or
other default, or impair any right consequent thereon.

                            TRUSTEE AND PAYING AGENTS

            Section 9.1. Appointment and Acceptance of Duties. (A) Brown
Brothers Harriman Trust Company, New York, New York, is hereby appointed as
Trustee. The Trustee shall signify its acceptances of the duties and obligations
of the Trustee by executing this Indenture. All provisions of this Article shall
be construed as extending to and including all the rights, duties and
obligations imposed upon the Trustee under the Agreement as fully for all
intents and purposes as if this Article were contained in the Agreement.

            (B) The Trustee is hereby appointed as Paying Agent for the Bonds.
The Authority may also from time to time appoint one or more other Paying Agents
in the manner and subject to the conditions set forth in Section 9.10 hereof for
the appointment of a successor Paying Agent. Each Paying Agent shall signify its
acceptance of the duties and obligations imposed upon it by this Indenture by
executing and delivering to the Authority and to the Trustee a written
acceptance thereof. The principal offices of the Paying Agents are designated as
the respective offices or agencies of the Authority for the payment of the

in the enforcement of any rights and powers hereunder, until it shall be
indemnified to its satisfaction against any and all reasonable costs and
expenses, outlays, and counsel fees and other disbursements, and against all
liability not due to its wilful misconduct, gross negligence or bad faith.

            Section 9.3. Responsibilities of Trustee. (A) The Trustee shall have
no responsibility in respect of the validity or sufficiency of this Indenture or
the security provided hereunder or the due execution hereof by the Authority, or

validity of any Bonds authenticated and delivered by the Trustee in accordance
with this Indenture or to see to the recording or filing (but not refiling) of
the Indenture or any financing statement or any other document or instrument
whatsoever. The recitals, statements and representations contained herein and in
the Bonds shall be taken and construed as made by and on the part of the
Authority and not by the Trustee, and it does not assume any responsibility for
the correctness of the same; except that the Trustee shall be responsible for
its representation contained in its certificate on the Bonds.


                                      -60-
<PAGE>

            (B) The Trustee shall not be liable or responsible because of the
failure of the Authority to perform any act required of it by the Indenture or
the Financing Documents or because of the loss of any moneys arising through the
insolvency or the act or default or omission of any depositary other than itself
in which such moneys shall have been deposited. The Trustee shall not be
responsible for the application of any of the proceeds of the Bonds or any other
moneys deposited with it and paid out, invested, withdrawn or transferred in
accordance herewith or for any loss resulting from any such investment or for
any interest thereon. The Trustee shall not be liable in connection with the
performance of its duties hereunder except for its own willful misconduct, gross
negligence or bad faith. The immunities and exemptions from liability of the
Trustee shall extend to its directors, officers, employees and agents.

            (C) The Trustee, prior to the occurrence of an event of default (as
defined in Section 8.1 hereof), undertakes to perform such duties and only such
duties as are specifically set forth in this Indenture. In case an event of
default has occurred the Trustee shall exercise such of the rights and powers
vested in it hereby and use the same degree of care and skill in their exercise,
as a prudent person would exercise under the circumstances in the conduct of his
own affairs.

            (D) The Trustee shall not be liable or responsible for the failure
of the Borrower to effect or maintain insurance on the Project as provided in
the Financing Documents nor shall it be responsible for any loss by reason of
want or insufficiency in insurance or by reason of the failure of any insurer in
which the insurance is carried to pay the full amount of any loss against which
it may have insured the Authority, the Borrower, the Trustee or any other
person.

            (E) The Trustee shall not be responsible for compliance by the
Borrower with the covenants under Sections 6.12, 6.13, 6.14 and 6.15 of the Loan

determining whether any certificate or report required by any such Section to be
delivered to the Trustee has been received in the prescribed form.

            Section 9.4. Compensation. The Trustee and Paying Agents shall be
entitled to receive and collect from the Borrower as provided in the Financing
Documents payment [reasonable fees for services rendered hereunder and] for all
advances, counsel fees and other expenses reasonably made or incurred by the
Trustee or Paying Agents in connection therewith.

            Section 9.5. Evidence on Which Trustee May Act. (A) In case at any
time it shall be necessary or desirable for the Trustee to make any
investigation concerning any fact preparatory to taking or not taking any
action, or doing or not doing anything, as such Trustee, and in any case in
which this Indenture or the Financing


                                      -61-
<PAGE>

Documents provides for permitting or taking any action, it may rely upon any
certificate required or permitted to be filed with it under the provisions
hereof or of the Financing Documents, and any such certificate shall be evidence
of such fact or protect it in any action that it may or may not take, or in
respect of anything it may or may not do, in good faith, by reason of the
supposed existence of such fact.

            (B) The Trustee shall be protected and shall incur no liability in
acting or proceeding, or in not acting or not proceeding, in good faith,
reasonably and in accordance with the terms of this Indenture or the Financing
Documents, upon any resolution, order, notice, request, consent, waiver,
certificate, statement, affidavit, requisition, bond or other paper or document
which it shall in good faith reasonably believe to be genuine and to have been
adopted or signed by the proper board or person, or to have been prepared and
furnished pursuant to any of the provisions of this Indenture or the Financing
Documents, or upon the written opinion of any attorney (who may be an attorney
for the Authority or the Borrower), engineer, appraiser, or accountant believed
by the Trustee to be qualified in relation to the subject matter.

            Section 9.6. Evidence of Signatures of Bondholders and Ownership of
Bonds. (A) Any request, consent, revocation of consent or other instrument which
this Indenture may require or permit to be signed and executed by the
Bondholders may be in one or more instruments of similar tenor, and shall be
signed or executed by such Bondholders in person or by their attorneys appointed
in writing. Proof of (i) the execution of any such instrument, or of any
instrument appointing any such attorney, or (ii) the holding by any person of
the Bonds shall be sufficient for any purpose of this Indenture (except as
otherwise herein expressly provided) if made in the following manner, or in any
other manner satisfactory to the Trustee, which may nevertheless in its
discretion require further or other proof in cases where it deems the same
desirable:

            (1) The fact and date of the execution by any Bondholder or his
      attorney of such instruments may be proved by a guarantee of the signature
      thereon by an officer of a bank or trust company or by the certificate of
      any notary public or other officer authorized to take acknowledgements of
      deeds, that the person signing such request or other instrument
      acknowledged to him the execution thereof, or by an affidavit of a witness
      of such execution, duly sworn to before such notary public or other
      officer. Where such execution is by an officer of a corporation or a
      member of a partnership, on behalf of such corporation, association or
      partnership, such signature guarantee, certificate or affidavit shall be
      accompanied by sufficient proof of his authority.


                                      -62-
<PAGE>

            (2) The ownership of registered Bonds and the amount, numbers and
      other identification, and date of holding the same shall be proved by the
      registry books.

            (B) Except as otherwise provided in Section 10.3 hereof with respect
to revocation of a consent, any request or consent by the holder of any Bond
shall bind all future holders of such Bond in respect of anything done or
suffered to be done by the Authority or the Trustee or any Paying Agent in
accordance therewith.

            Section 9.7. Trustee and Paying Agents May Deal in Bonds and With
Borrower. Any national banking association, bank or trust company acting as a
Trustee, or Paying Agent, and its directors, officers, employees or agents, may
in good faith buy, sell, own, hold and deal in any of the Bonds and may join in
any action which any Bondholder may be entitled to take and may otherwise deal
with the Borrower with like effect as if such association, bank or trust company
were not such Trustee or Paying Agent.

            Section 9.8. Resignation or Removal of Trustee. (A) The Trustee may
resign and thereby become discharged from the trusts created under this
Indenture by notice in writing to be given to the Authority and by notice
mailed, postage prepaid to the Bondholders not less than sixty days before such
resignation is to take effect, but such resignation shall take effect
immediately upon the appointment of a successor Trustee, pursuant to Section 9.9
hereof, if such successor Trustee shall be appointed before the time specified
by such notice and shall accept such trust.

            (B) The Trustee may be removed at any time by an instrument or
concurrent instruments in writing, filed with the Trustee and signed by the
holders of not less than a majority in principal amount of the Bonds then
Outstanding or their attorneys-in-fact duly authorized. The Trustee shall
promptly give notice of such filing to the Authority.

            Section 9.9. Successor Trustee. (A) If at any time the Trustee shall
resign, or shall be removed, be dissolved or otherwise become incapable of
acting or shall be adjudged a bankrupt or insolvent, or if a receiver,
liquidator or conservator thereof, or of its property, shall be appointed, or if
any public officer shall take charge or control of the Trustee or of its
property or affairs, the position of Trustee shall thereupon become vacant. If
the position of Trustee shall become vacant for any of the foregoing reasons or
for any other reason, the Authority shall appoint a successor Trustee to fill
such vacancy provided that if the Authority fails to make such appointment, a
successor Trustee may be appointed by a majority of the holders of Outstanding
Bonds. Within twenty days after such appointment, the Authority shall cause
notice of such appointment to be mailed, postage prepaid, to all Bondholders.


                                      -63-
<PAGE>

            (B) At any time within one year after such vacancy shall have
occurred, the holders of a majority in principal amount of the Bonds then
Outstanding, by an instrument or concurrent instruments in writing, signed by
such Bondholders or their attorneys-in-fact thereunto duly authorized and filed
with the Authority, may appoint a successor Trustee, which shall, immediately
and without further act, supersede any Trustee theretofore appointed. If no
appointment of a successor Trustee shall be made pursuant to the foregoing
provisions of this Section, the holder of any Bond then Outstanding or any
retiring Trustee may apply to any court of competent jurisdiction to appoint a
successor Trustee. Such court may thereupon, after such notice, if any, as such
court may deem proper and prescribe, appoint a successor Trustee.

            (C) Any Trustee appointed under this Section shall be a national
banking association or a bank or trust company duly organized under the laws of
the State or under the laws of any state of the United States authorized to
exercise corporate trust powers. At the time of its appointment, any successor
Trustee shall have a capital stock and surplus aggregating not less than
$10,000,000 (provided, however, that so long as the Original Purchaser is the
owner of all of the Bonds outstanding hereunder such requirement may be waived
by the Original Purchaser in its sole discretion).

            (D) Every successor Trustee shall execute, acknowledge and deliver
to its predecessor, and also to the Authority, an instrument in writing
accepting such appointment, and thereupon such successor Trustee, without any
further act, deed, or conveyance, shall become fully vested with all moneys,
estates, properties, rights, immunities, powers and trusts, and subject to all
the duties and obligations of its predecessor, with like effect as if originally
named as such Trustee; but such predecessor shall, nevertheless, on the written
request of its successor or of the Authority, and upon payment of the
compensation, expenses, charges and other disbursements of such predecessor
which are due and payable pursuant to Section 9.4 hereof, execute and deliver an
instrument transferring to such successor Trustee all the estate, properties,
rights, immunities, powers and trusts of such predecessor (except for such
predecessor's rights to be indemnified). Every predecessor Trustee shall also
deliver all property and moneys held by it under the Indenture to its successor.
Should any instrument in writing from the Authority be required by any successor
Trustee for more fully and certainly vesting in such Trustee, the estate,
properties, rights, immunities, powers and trusts vested or intended to be
vested in the predecessor Trustee any such instrument in writing shall, on
request, be executed, acknowledged and delivered by the Authority. Any successor
Trustee shall promptly notify the Paying Agents of its appointment as Trustee.

            (E) Any company into which the Trustee may be merged or converted or
with which it may be consolidated or any company


                                      -64-
<PAGE>

resulting from any merger, conversion or consolidation to which it shall be a
party or any company to which the Trustee may sell or transfer all or
substantially all of its corporate trust business, provided such company shall
be a national banking association or a bank or trust company duly organized
under the laws of any state of the United States, and shall be authorized by law
to perform all the duties imposed upon it by the Indenture, shall be the
successor to such Trustee without the execution or filing of any paper or the
performance of any further act.

            (F) Any Trustee which becomes incapable of acting as Trustee shall
pay over, assign and deliver to its successor any moneys, funds or investments
held by it and shall render an accounting to the Authority.

            Section 9.10. Resignation or Removal of Paying Agent; Successors.
(A) Any Paying Agent may at any time resign and be discharged of the duties and
obligations created by the Indenture by giving at least sixty days' written
notice to the Authority and the Trustee. Any successor Paying Agent shall be
appointed by the Authority, with the approval of the Trustee, and shall be a
bank or trust company duly organized under the laws of any state of the United
States or a national banking association, having a capital stock and surplus
aggregating at least $5,000,000 (provided that, so long as the Original
Purchaser is the owner of all of the Bonds Outstanding hereunder such
requirement may be waived by the Original Purchaser in its sole discretion), and
willing and able to accept the office on reasonable and customary terms and
authorized by law to perform all the duties imposed upon it by this Indenture.

            (B) In the event of the resignation or removal of any Paying Agent,
such Paying Agent shall pay over, assign and deliver any moneys held by it as
Paying Agent to its successor, or if there be no successor, to the Trustee. In
the event that for any reason there shall be a vacancy in the office of any
Paying Agent, the Trustee shall act as such Paying Agent.

            Section 9.11. Project Equipment Description. (A) The Trustee shall
maintain a list of the property constituting the Project Equipment in the form
of the descriptions furnished by the Borrower pursuant to the Agreement.

            (B) The description of each listed item of collateral constituting
the Project Equipment contained in an Appendix to the Agreement shall be in a
form sufficient for the creation and perfection of a security interest therein
under the Uniform Commercial Code of the State pursuant to the Security
Agreement, and the Borrower shall file or cause the filing of all UCC-1
financing statements in all places necessary to perfect the security interest of
the Trustee therein. Such list, as from time to time amended in accordance with
this Indenture and the Agreement, shall be maintained by the Trustee at its
principal


                                      -65-
<PAGE>

office available for reasonable inspection during normal business hours by
interested persons.

            Section 9.12. Continuation Statements. The Trustee shall cause all
continuation statements necessary to preserve and protect the security interest
of the Trustee in the Project Equipment pursuant to the Security Agreement as
assignee of the Authority's rights as secured party thereunder and of the
Trustee in the collateral pledged by the Authority in the granting clauses
hereof to be filed in the applicable State and local offices so as to continue
the effectiveness of the financing statements furnished by the Borrower to the
Trustee pursuant to the Uniform Commercial Code of the State.

            Section 9.13. Obligation to Report Defaults. The Trustee shall give
the Authority an annual report as to whether or not it has become aware of any
failure of any party to the Agreement or to the Indenture to comply with the
provisions thereof and, if so, shall specify the details thereof. Subject to the
same limitations, set forth in the last sentence of Section 8.10, upon becoming
aware of any condition or event which constitutes, or with the giving of notice
or the passage of time would constitute, an event of default under the Financing
Documents or this Indenture, the Trustee shall deliver to the Authority a
written notice stating the existence thereof and the action it proposes to take
with respect thereto.

            Section 9.14. Payments Due on non-Business Days. In any case where
the date of maturity of interest on or principal of the Bonds or the date fixed
for redemption of any Bonds shall, in the city of payment, be a day other than a
Business Day, then payment of such amount shall be made on the next succeeding
Business Day with the same force and effect as if made on the date of maturity
or the date fixed for redemption, and no interest shall accrue for the period
after such date.

            Section 9.15. Moneys Held for Particular Bonds. The amounts held by
the Trustee or Paying Agents for the payment of the interest, principal or
Redemption Price due on any date with respect to particular Bonds, on and after
such date and pending such payment, shall be set aside on its books and held in
trust by it for the holders of the Bonds entitled thereto.

            Section 9.16. Appointment of Co-Trustee. (A) It is the purpose of
this Indenture that there shall be no violation of any law of any jurisdiction
denying or restricting the right of banking corporations or associations to
transact business as trustee in such jurisdiction. It is recognized that in case
of litigation under this Indenture or the Agreement, and in particular in case
of the enforcement of either on default, or in case the Trustee deems that by
reason of any present or future law of any jurisdiction it may not exercise any
of the powers, rights or remedies herein granted to the Trustee or hold title to
the properties, in trust,


                                      -66-
<PAGE>

as herein granted, or take any other action which may be desirable or necessary
in connection therewith, it may be necessary that the Trustee appoint an
additional individual or institution as a separate trustee or co-trustee. The
following provisions of this Section are adapted to these ends.

            (B) In the event that the Trustee appoints an additional individual
or institution as a separate trustee or co-trustee, each and every remedy,
power, right, claim, demand, cause of action, immunity, estate, title, interest
and lien expressed or intended by this Indenture to be exercised by or vested in
or conveyed to the Trustee with respect thereto shall be exercisable by and vest
in such separate trustee or co-trustee but only to the extent necessary to
enable such separate trustee or co-trustee to exercise such powers, rights and
remedies, and every covenant and obligation necessary to the exercise thereof by
such separate trustee or co-trustee shall run to and be enforceable by either of
them.

            (C) Should any instrument in writing from the Authority be required
by the separate trustee or co-trustee so appointed by the Trustee for more fully
and certainly vesting in and confirming to him or it such properties, rights,
powers, trusts, duties and obligations, any and all such instruments in writing
shall, on request, be executed, acknowledged and delivered by the Authority. In
case any separate trustee or co-trustee, or a successor to either, shall die,
become incapable of acting, resign or be removed, all the estates, properties,
rights, powers, trusts, duties and obligations of such separate trustee or
co-trustee, so far as permitted by law, shall vest in and be exercised by the
Trustee until the appointment of a new trustee or successor to such separate
trustee or co-trustee.

            Section 10.1. Limitation on Modifications. This Indenture shall not
be modified or amended in any respect except as provided in and in accordance
with and subject to the provisions of this Article.

            Section 10.2. Supplemental Indentures Without Bondholders' Consent.

Indentures without consent of the Bondholders for any of the following purposes:

      Indenture or in any description of property subject to the lien hereof.

            (2) To amend any provision of this Indenture, in a manner which is
      not materially adverse to the interests of the Bondholders and does not
      impair the security for the Bonds.

            (3) To grant to or confer upon the Trustee for the benefit of the
      Bondholders any additional rights, remedies, powers, authority or security
      which may lawfully be granted or conferred and which are not contrary to

            (4) To add to the covenants and agreements of the Authority in this
      Indenture other covenants and agreements to be observed by the Authority

            (5) To add to the limitations and restrictions in this Indenture

            (6) To confirm, as further assurance, any pledge under, and the
      subjection to any lien or pledge created or to be created by, this
      Indenture, of the properties of the Project, or revenues or other income

      revenues, properties or collateral.

            (7) To authorize the issuance of Additional Bonds and prescribe the
      terms, forms and details thereof not inconsistent with this Indenture.

            (B) Before the Authority shall adopt any Supplemental Indenture

opinion of counsel satisfactory to the Trustee


                                      -68-
<PAGE>

stating that such Supplemental Indenture is authorized or permitted by this
Indenture and complies with its terms, and that upon enactment it will be valid
and binding upon the Authority in accordance with its terms.

            (C) Notwithstanding the foregoing, so long as the Original Purchaser
is the Owner of all of the Initial Bonds Outstanding, no amendment or supplement
to this Indenture shall be effected without the written consent of the Original
Purchaser.

            Section 10.3. Supplemental Indentures with Bondholders' Consent. (A)
Subject to the terms and provisions contained in this Article, the holders of
not less than a majority in aggregate principal amount of the Bonds then
Outstanding shall have the right from time to time, to consent to and approve
the adoption by the Authority of any Supplemental Indenture as shall be deemed
necessary or desirable by the Authority for the purpose of modifying, altering,
amending, adding to or rescinding, in any particular, any of the terms or
provisions contained herein. Nothing herein contained shall permit, or be
construed as permitting, without the consent of all of the Bondholders (i) a
change in the terms of redemption or maturity of the principal of or the
interest on any Outstanding Bond, or a reduction in the principal amount or
Redemption Price of any Outstanding Bond or the rate of interest thereon,
without the consent of the holder of such Bond, or (ii) the creation of a lien
upon or pledge of revenues or other income from or in connection with the
Project other than the lien or pledge created by this Indenture or (iii) a
preference or priority of any Bond or Bonds over any other Bond or Bonds, or
(iv) a reduction in the aggregate principal amount of the Bonds required for
consent to such Supplemental Indenture.

            (B) If at any time the Authority shall determine to adopt any
Supplemental Indenture for any of the purposes of this Section, it shall cause
notice of the proposed Supplemental Indenture to be mailed, postage prepaid, to
all Bondholders. Such notice shall briefly set forth the nature of the proposed
Supplemental Indenture, and shall state that a copy thereof is on file at the
offices of the Trustee for inspection by all Bondholders.

            (C) Within one year after the date of such notice, the Authority may
adopt such Supplemental Indenture in substantially the form described in such
notice only if there shall have first been filed with the Authority (i) the
written consents of holders of not less than a majority in aggregate principal
amount of the Bonds then Outstanding and (ii) an opinion of counsel satisfactory
to the Trustee stating that such Supplemental Indenture is authorized or
permitted by this Indenture and complies with its terms, and that upon adoption
it will be valid and binding upon the Authority in accordance with its terms.
Each valid consent shall be effective only if accompanied by proof of the
holding, at the date of such consent, of the Bonds with respect to which such


                                      -69-
<PAGE>

consent is given. A certificate or certificates by the Trustee that it has
examined such proof and that such proof is sufficient in accordance with this
Indenture shall be conclusive that the consents have been given by the holders
of the Bonds described in such certificate or certificates. Any such consent
shall be binding upon the holder of the Bonds giving such consent and upon any
subsequent holder of such Bonds and of any Bonds issued in exchange therefor
(whether or not such subsequent holder thereof has notice thereof), unless such
consent is revoked in writing by the holder of such Bonds giving such consent or
a subsequent holder thereof by filing such revocation with the Trustee prior to
the adoption of such Supplemental Indenture.

            (D) If the holders of not less than the percentage of Bonds required
by this Section shall have consented to and approved the execution thereof as
herein provided, no holder of any Bond shall have any right to object to the
enactment of such Supplemental Indenture, or to object to any of the terms and
provisions contained therein or the operation thereof, or in any manner to
question the propriety of the adoption thereof, or to enjoin or restrain the
Authority from adopting the same or from taking any action pursuant to the
provisions thereof.

            (E) Upon the adoption of any Supplemental Indenture pursuant to the
provisions of this Section, this Indenture shall be deemed to be modified and
amended in accordance therewith, and the respective rights, duties and
obligations under this Indenture of the Authority, the Trustee and all holders
of Bonds then Outstanding shall thereafter be determined, exercised and enforced
under this Indenture, subject in all respects to such modifications and
amendments.

            (F) Notwithstanding the foregoing, so long as the Original Purchaser
is the Owner of all of the Initial Bonds Outstanding, no amendment or supplement
to this Indenture shall be effected without the written consent of the Original
Purchaser.

            Section 10.4. Supplemental Indenture Part of the Indenture. Any
Supplemental Indenture adopted in accordance with the provisions of this Article
shall thereafter form a part of this Indenture and all the terms and conditions
contained in any such Supplemental Indenture as to any provisions authorized to
be contained therein shall be deemed to be part of the terms and conditions of
this Indenture for any and all purposes. The Trustee shall execute any
Supplemental Indenture adopted in accordance with the provisions of Sections
10.2 or 10.3 hereof; provided, however, that the Trustee may refuse to execute
any Supplemental Indenture which it reasonably believes would subject it to
liability or materially change its rights, duties or obligations hereunder in a
manner adverse to the Trustee.

            Section 10.5. Trustee Authorized to Join in Supplements; Reliance on
Counsel. The Trustee is authorized to join with the


                                      -70-
<PAGE>

Authority in the execution and delivery of any Supplemental Indenture permitted
by this Article X and in so doing shall be fully protected by an opinion of
counsel that such Supplemental Indenture is so permitted and has been duly
authorized by the Authority and that all things necessary to make it a valid and
binding agreement have been done.

                        AMENDMENTS OF FINANCING DOCUMENTS

            Section 11.1. Rights of Borrower. Anything herein to the contrary
notwithstanding, any Supplemental Indenture under Article X hereof which affects
any rights, powers and authority of the Borrower under the Financing Documents
or of any subsequent user of the Project or requires a revision of the Financing
Documents or subsequent agreement with respect to the Project shall not become
effective unless and until the Borrower or such subsequent user, as the case may
be, shall have given its written consent signed by its duly Authorized
Representative to such Supplemental Indenture.

            Section 11.2. Amendments of Financing Documents Not Requiring
Consent of Bondholders. The Authority and the Trustee may, without the consent
of or notice to the Bondholders, consent to any amendment, change or
modification of the Financing Documents for the purpose of curing any ambiguity
or formal defect therein or making any amendment to any provision of the
Financing Documents which is not materially to the prejudice of the Trustee or
the holders of the Bonds. The Trustee shall have no liability to any Bondholder
or any other person for any action taken by it in good faith pursuant to this
Section and shall be fully protected by an opinion of counsel that any such
action is permitted by this Section.

the Owner of all of the Initial Bonds Outstanding, no amendment or supplement to
this Indenture shall be effected without the written consent of the Original
Purchaser.

Trustee shall not consent to any amendment, change or modification of the
Financing Documents, including the substitution of an assignee for the Borrower

except in the event of a corporate reorganization of the Borrower, without
mailing of notice and the written approval or consent of the holders of not less
than a majority in aggregate principal amount of the Bonds at the time
Outstanding given and procured as in Section 10.3 hereof provided. If at any
time the Borrower or a subsequent user of the Project shall request the consent
of the Trustee to any such proposed amendment, change or modification, the
Trustee shall cause notice of such proposed amendment, change or modification to
be mailed in the same manner as is provided in Article X hereof with respect to
Supplemental Indentures. Such notice shall briefly set forth the nature of such
proposed amendment, change or modification and shall state that copies of the
instrument embodying the same are on file


                                      -72-

            Notwithstanding the foregoing, so long as the Original Purchaser is
the Owner of all of the Initial Bonds Outstanding, no amendment or supplement to
this Indenture shall be effected without the written consent of the Original
Purchaser.

                                   ARTICLE XII

                             DISCHARGE OF INDENTURE

            Section 12.1. Defeasance. (A) If the Authority shall pay or cause to
be paid, or there shall otherwise be paid, to the holders of all Bonds the
principal or Redemption Price, if applicable, interest and all other amounts due
or to become due thereon or in respect thereof, at the times and in the manner
stipulated therein and in this Indenture, and if all the fees, expenses and
liabilities of the Trustee shall have been paid or provided for, then the pledge
of any revenues or receipts from or in connection with the Financing Documents
or the Project under this Indenture and the estate and rights hereby granted,
and all covenants, agreements and other obligations of the Authority to the
Bondholders hereunder shall thereupon cease, terminate and become void and be
discharged and satisfied and such Bonds shall thereupon cease to be entitled to
any lien, benefit or security hereunder, except as to moneys or securities held
by the Trustee or the Paying Agents as provided below in this subsection. At the
time of such cessation, termination, discharge and satisfaction, (1) the Trustee
shall cancel and discharge the lien of this Indenture and of the Mortgage and
the Security Agreement and execute and deliver to the Borrower all such
instruments as may be appropriate to satisfy such liens and to evidence such
discharge and satisfaction, and (2) the Trustee, the Authority and the Paying
Agents shall pay over or deliver to the Borrower or on its order all moneys or
securities held by them pursuant to the Indenture which are not required (a) for
the payment of principal or Redemption Price, if applicable, or interest on
Bonds not theretofore surrendered for such payment or redemption, or (b) for the
payment of all such other amounts due or to become due under the Financing
Documents.

            (B) Bonds or interest installments for the payment or redemption of
which moneys (or Federal Securities, the principal of and interest on which when
due, together with the moneys, if any, set aside at the same time, will provide
funds sufficient without reinvestment for such payment or redemption) shall then
be set aside and held in trust by the Trustee or Paying Agents, whether at or
prior to the maturity or the redemption date of such Bonds, shall be deemed to
have been paid within the meaning and with the effect expressed in subsection
(A) of this Section, if (a) in case any such Bonds are to be redeemed prior to
the maturity thereof, all action necessary to redeem such Bonds shall have been
taken and notice of such redemption shall have been duly given or provision
satisfactory to the Trustee shall have been made for the giving of such notice,
and (b) if the maturity or redemption date of any such Bond shall not then have
arrived, provision shall have been made by deposit with the Trustee or other
methods satisfactory to the Trustee for the payment to the holders of any such
Bonds upon surrender thereof, whether or not prior to the maturity or redemption
date thereof, of the full amount to which they would be entitled by way of
principal or Redemption Price and interest and


                                      -74-
<PAGE>

all other amounts then due under the Financing Documents to the date of such
maturity or redemption, and provision satisfactory to the Trustee shall have
been made for the mailing of a notice to, the holders of such Bonds that such
moneys are so available for such payment.

            Notwithstanding the foregoing, so long as the Original Purchaser is
the owner of all of the Initial Bonds Outstanding, no defeasance of the Initial
Bonds shall be effected in accordance with this subsection (B) without the prior
written consent of the Original Purchaser, which consent may be granted or
withheld by the Original Purchaser in its sole discretion and, if granted, may
be conditioned upon such further provision with respect thereto as the Original
Purchaser shall reasonably require.

                            TAX REGULATORY AGREEMENT

      THIS TAX REGULATORY AGREEMENT, dated as of December 12, 1997, is by and
among the CONNECTICUT DEVELOPMENT AUTHORITY, a body politic and corporate
constituting a public instrumentality and political subdivision of the State of
Connecticut (the "Authority"), Sonics & Materials, Inc., a corporation, duly
constituted and validly existing under the laws of the State of Delaware
("Company"), and Brown Brothers Harriman Trust Company, as trustee (the
"Trustee") under the Indenture of Trust dated as of December 1, 1997, which
parties agree as follows:

                              W I T N E S S E T H:

      WHEREAS, pursuant to a bond resolution duly adopted and the Indenture, the
Authority is issuing the Connecticut Development Authority $3,810,000 Variable
Rate Demand Industrial Development Bonds (Sonics & Materials, Inc. Project)
Series 1997 ("Bonds") on the date hereof and, pursuant to a loan agreement with
the Company, is loaning the proceeds of the Bonds to the Company in order to
finance and refinance the acquisition, construction and equipping of the
Project;

      WHEREAS, the acquisition, construction and equipping of the Project will
proceed with due diligence;

      WHEREAS, in order to ensure that the requirements of the Internal Revenue
Code of 1986, as amended, are and will continue to be met, the Authority, the
Company, and the Trustee have determined to enter into this Tax Regulatory
Agreement in order to set forth certain representations, expectations,
conditions and covenants relating to the activities of the Authority, the
Company and the Trustee, the Bonds, the Project and the application of proceeds
of the Bonds and other related amounts and unexpended proceeds and other amounts
relating to the Bonds;

      NOW, THEREFORE, in consideration of the mutual covenants and undertakings
set forth herein and other good and valuable consideration, the receipt and
sufficiency of which hereby are acknowledged, the Authority, the Company, and
the Trustee hereby agree as follows:
<PAGE>

                                    ARTICLE I

                         DEFINITIONS AND INTERPRETATION

      Section 1.1. Definitions. Except as otherwise provided in this section
1.1, capitalized terms used in this Agreement (including the recitals to this
Agreement) shall have the meaning given such terms in the Indenture, or if not
defined therein, in the Loan Agreement. The following words and terms as used in
this Tax Regulatory Agreement shall have the following meanings:

      "Act" means Connecticut General Statutes, Section 32-1a et seq.

      "Administrative Costs" includes reasonable, direct costs paid by or on
behalf of an issuer for brokerage or selling commissions (but not legal and
accounting fees), investment advisory fees, recordkeeping, safekeeping, custody,
and similar costs, but not general overhead and similar indirect costs (such as
employee salaries and office expenses) and rebate computation costs.
Administrative costs include a brokerage commission, but only to the extent that
the Present Value of the commission does not exceed the Present Value of annual
payments equal to .05 percent of the weighted average amount reasonably expected
to be invested each year of the term of the contract, for an investment contract
purchased with Gross Proceeds regardless of whether the brokerage commission is
paid or incurred on behalf of the Authority or the provider of the investment
contract. For this purpose, Present Value is computed using the taxable discount
rate used by the parties to compute the commission, or, if not readily
ascertainable, a reasonable taxable discount rate. Administrative costs are not
reasonable unless they are comparable to administrative costs that would be
charged for the same investment or a reasonable comparable investment if the
investment were made from a source of funds other than gross proceeds of
tax-exempt bonds. In the case of publicly offered regulated investment companies
(as defined in Code Section 67(c)(2)(B)) and Commingled Funds in which the
Issuer and related parties own less than a 10% interest, reasonable
administrative costs include indirect costs. For any semi-annual period, a
Commingled Fund satisfies the 10% requirement if, based on average amounts on
deposit, this requirement is satisfied for the prior semi-annual period and the
fund does not accept deposits that would cause to fail to meet this requirement.

      "Aggregate Face Amount" means the aggregate face amount of the Bonds
determined in accordance with Section 144(a) of the Code.

      "Annual Debt Service" means the scheduled amount of interest and
amortization of principal payable for any Bond Year with respect to the issue.
For purposes of determining the debt


                                      -2-
<PAGE>

service on an issue, there shall not be taken into account amounts scheduled
with respect to any obligation (or portion thereof) that has been retired before
the beginning of the Bond Year.

      "Applicable Elected Representative" means the Governor of the State of
Connecticut.

      "Average Economic Life" means the average reasonably expected economic
life, within the meaning of Section 147(b) of the Code, of the assets financed
with the proceeds of the Bonds.

      "Average Maturity" means the average maturity of the Bonds within the
meaning of Section 147(b) of the Code.

      "Bona Fide Debt Service Fund" means "Bona Fide Debt Service Fund" as such
term is defined in Treas. Reg. ss. 1.148-1(b).

      "Bond" or "Bonds" means the Authority's $3,810,000 Industrial Development
Bonds (Sonics & Materials, Inc. Project) Series 1997.

      "Bond Counsel" means a firm of attorneys which is nationally recognized as
having experience in the field of municipal finance and which is satisfactory to
the Authority.

      "Bond Proceeds" means the amount paid to the Authority by the initial
purchasers of the Bonds as the purchase price, including accrued interest as
defined in Treas. Reg. 1.148-1(b), if any.

      "Bond Year" shall mean the period beginning on the date hereof (the date
of delivery of the Bonds) and ending on December 12, 1998; each subsequent
one-year period ending on the anniversary of the day so selected, during which
the Bonds are outstanding; and the period ending on the date the last
outstanding Bond is discharged and beginning the day after the end of the
previous Bond Year.

      "Gross Proceeds" shall mean:

      (i) the proceeds derived by the Authority from the sale of the Bonds;

      (ii) amounts held in the Debt Service Fund;

      (iii) other amounts pledged directly or indirectly as security for the
payment of debt service on the Bonds or for any credit enhancement provider,
including amounts, if any, pledged by the Company or any Related Person as

the Project if the


                                      -5-
<PAGE>

Bonds had not been issued). The mere availability or preliminary earmarking of
such amounts for the Project is not a sufficient connection. Amounts held under
an agreement to maintain the amounts at a particular level for the direct or
indirect benefit of the Bondholders or any guarantor of the Bonds are
replacement proceeds unless the Authority or Company can grant rights in the
amounts that are superior to the rights of the Holders or guarantor, or the
amounts are reasonably needed at a level that is tested no sooner than every six

of each succeeding fifth Bond Year.

      "Investment" shall mean any security or obligation, any annuity contract,
or any other investment-type property. An investment includes any property held
principally as a passive vehicle to provide income, e.g., a prepayment for
property or services where the principal purpose is to receive an investment
return over the time the prepayment otherwise would be made. A prepayment is not
an investment if it is made for a substantial non-investment purpose and there
is no commercially reasonable alternative to the prepayment or if it is made
substantially on the same terms as the terms permitted a substantial percentage
of similarly situated persons who are not beneficiaries of tax-exempt financing.
An investment includes a contract that would be a hedge (within the meaning of
Treas. Reg. ss.1.148-4(h)) except that it contains a significant investment
element. An interest rate cap contains a significant investment element if the


                                      -6-
<PAGE>

payments for the cap are made more quickly than in level annual installments
over the term of the cap or the cap hedged a bond that is not a variable rate
debt instrument under Treas. Reg. ss.1.1275-5. A cap generally contains a
significant investment element if the cap rate is less than the on-market swap
rate on the date the cap is entered into. A Tax-Exempt Investment is not an
Investment.

incurred in connection with the borrowing, including, but not limited to,
underwriter's spread, discount or fees, counsel fees (including bond counsel,
underwriter's counsel, Authority's counsel, Company's counsel and specialized
counsel fees), initial fee of the Trustee, fees to the Authority, rating agency
fees, holder fees, accountant fees, printing costs and costs incurred in
connection with obtaining the required public approval for the issuance of the
Bonds.

      "Issue Price of the Bonds" shall mean the issue price as defined in Code
Section 1273 and 1274 and generally is the first price at which a substantial
(i.e., 10%) amount of the Bonds is sold to the public (not including bond
houses, brokers, or a similar person or organizations acting in the capacity of
underwriters or wholesalers). The issue price of Bonds for which a bona fide
public offering is made is determined as of the date of sale based on reasonable
expectations regarding the initial public offering price.

premium (or in the case of investments only, if acquired after its issue date
not more than a De Minimis Amount of market discount), (ii) issued for a price
that does not include accrued interest other than Pre-Issuance Accrued Interest,
(iii) bears interest at either a single, fixed rate at all times or variable
interest calculated pursuant to an objective index (see section 1275 of the
Code), payable at least annually and (iv) its lowest redemption price is not
less than its outstanding principal. The Bonds are Plain Par Bonds.

      "Pre-issuance Accrued Interest" means amounts representing interest that
accrued on an obligation for a period not greater than one year before its issue
date but only if paid within one year after the issue date.

      "Present Value" shall mean an amount to be determined by using the formula
PV = FV divided by (1+i)^n, where PV equals the Present Value of the amount to
be received or paid, FV equals the amount to be received or paid, i equals the
discount rate (expressed as a decimal) divided by the number of compounding
intervals in a year and n equals the sum of the number of whole compounding
intervals beginning on the date as of which the present value is computed and
ending on the date the amount is to be received or paid, and a fraction, the
numerator of which is the length of any short compounding interval during such
period, and the denominator of which is the length of a whole compounding
interval.

      "Present Value of a Bond" in the case of any bond shall mean the Present
Value as of a date of all unconditionally payable payments after such date of
interest on and principal of the bond and Qualified Guarantee payments assuming
its retirement on its final maturity date and using the Yield of such Bond as
the discount rate. The Present Value of a bond subject to the same mandatory
sinking fund installment payment schedule as other Bonds (e.g., term bonds
subject to mandatory sinking fund installment payments) shall be computed in the
same manner, except that the composite Yield of all such Bonds is treated as the
Yield of each such Bond and each mandatory sinking fund installment payment date
is treated as a final maturity date. The Present Value of a Variable Yield Bond
shall be computed using the initial interest rate on the bond as set by the
interest rate setting mechanism to determine the interest payments. If such
substantially identical Bonds have original issue discount not in excess of 1/4%
times the product of the stated redemption price and the number of years to the
weighted average maturity of the


                                      -8-
<PAGE>

bonds, the bonds must be treated as redeemed at its outstanding principal amount
plus accrued unpaid interest.

      "Present Value of the Investment" shall mean the Present Value as of a
date of all unconditionally payable receipts to be received from and payments to
be paid for the investment after that date, using the Yield on the investment as
the discount rate. All yield restricted investments (other than the Loan
Agreement) may be treated as a single investment with a single yield, whether or
not held concurrently. All yield restricted investments allocable to a refunding
issue that are held in one or more Refunding Escrows are treated as a single
investment with a single yield, whether or not held concurrently.

      "Principal User" means any principal user of the Project within the
meaning of Section 144(a)(2)(B) of the Code and Prop. Treas. Reg. ss.

fair rental value under any formal or informal agreement or, under the
particular facts and circumstances, anyone who is a principal customer of the
Project, or anyone who is a Related Person to any of the foregoing. The term
"principal customer" means any person who purchases output of the Project under
a contract if the percentage of output taken or to be taken by such person
multiplied by a fraction the numerator of which is the term of such contract and
the denominator of which is the economic life of the Project, exceeds 10%, and
if such person has an extraordinary degree of control over the use and
operations of the Project, or a part thereof. In the case of a person who
purchases output of an electric or thermal energy, gas, water or other similar
facility, such person is a principal customer if the total output purchased by
such person during any one-year period beginning with the date the facility is
placed in service is more than 10 percent of the facility's output during each
such period. Co-owners or co-lessees who are shareholders in a corporation or
who are collectively treated as a partnership subject to subchapter K under
section 761(a) of the Code are not treated as Principal Users merely by reason
of their ownership of corporate or partnership interests.

      "Proceeds" means Sale Proceeds and Investment Proceeds.

      "Project" means, collectively, the financing and refinancing with the
proceeds of the Bonds of (i) the acquisition of approximately 7.5 acres of land,

excluded from gross income pursuant to Section 103 of the Code and which is not
a specified private activity bond as defined in Section 57(a)(5)(C) of the Code
(hereafter "AMT bond"). For this purpose, an obligation the interest on which is
excluded from gross income pursuant to Section 103 of the Code shall include an

foregoing.

      "Universal Cap" shall mean as of any required date of computation, the
value of all Bonds then outstanding. The value of a Bond shall equal the Present
Value of the Bond but using the Yield on the issue of which such Bonds is a
part, or if the Bonds are Plain Par Bonds, the outstanding principal amount of
Bonds shall be their value.

      "Value of a Bond" means in the case of a Plain Par Bond, its outstanding
principal amount plus accrued, unpaid interest and in the case of any other Bond
is its Present Value.

      "Value of an Investment" shall mean the following:

      A. In the case of an Investment acquired directly with Gross Proceeds
which is:

      (i)   a Plain Par Investment, the outstanding principal thereof plus
            accrued interest;

      (ii)  a Fixed Rate Investment, its Present Value;

However, at the option of the Authority, any Investment may be valued at its
Fair Market Value. In the case of transferred proceeds, the method of valuing
investments for the refunding bonds must be consistent with the valuing method
for the refunded bonds.

      B. In the case of an Investment allocated or reallocated to Bonds (other
than as a result of the application of the transferred proceeds rules, Universal
Cap rule, or the commingled fund rules), its Fair Market Value. Nonpurpose

a Fixed Yield Issue.

      "Weighted Average Rate of Interest" of an obligation for any period means
the total interest paid or deemed paid during such period divided by the product
of (i) the principal amount of such obligation, and (ii) the amount of time from
the beginning of such period that the obligation is outstanding (expressed in
percentage of years). Weighted Average Rate of Interest for two or more
obligations for any period means the total interest paid during such period
divided by the sum of the products described above.

      "Yield" except as otherwise modified herein, means that discount rate
which when used in computing (by the economic accrual method using a 360 day
year semi-annual compounding and other reasonable standard financial accounting
conventions, consistently applied) the Present Value of all unconditionally
payable receipts on an obligation produces an amount equal to the Present Value
of all unconditionally payable payments to acquire the obligation.

      "Yield-to-Maturity" shall mean, with respect to a Bond, the Yield which
when used in computing the Present Value of payments of principal of and
interest on a Bond, assuming its retirement on its final maturity date, produces
an amount equal to the initial offering price of the Bond to the public (not
including bond houses or brokers or other persons or organizations acting in the
capacity of underwriters or wholesalers). In the case of Bonds subject to the
same mandatory Sinking Fund Installment payment schedule, the composite
Yield-to-Maturity of such Bonds is determined by assuming the Bonds are retired
in accordance with such schedule and by treating the mandatory Sinking Fund
Installment payment dates as final maturity dates.

      "Yield Reduction Payments" means the payments described in Section 8.7.

Size.

      (a) The Authority has complied or will comply with the information
reporting requirements applicable to the issuance of the Bonds under Section
149(e) of the Code.

      (b) The limit on the amount of Private Activity Bonds as defined in the

exceed 2% of the Issue Price of the Bonds. The Company shall provide for the
payment of all Issuance Costs in excess of 2% of the Issue Price of the Bonds
from other available money and not from the proceeds of any obligation the
interest on which is excludable from gross income for federal income tax
purposes under Section 103(a) of the Code sold by a governmental unit within 15

investment tax credit or cost recovery deductions) by or on behalf of the
Company more than eighteen months before the Date of Issue.

      (b) The amount of earnings expected to be received from the investment of
Bond proceeds is as shown in Schedule D-1. Such estimated investment earnings is
based on a projected expenditure schedule for Bond proceeds that is consistent
with the schedule used to estimate interest during acquisition and construction

      (c) The amounts shown in Schedule D-1 as Issuance Costs consist only of
costs which are directly related to and necessary for the issuance of the Bonds
and the sum of such amounts do not exceed 2% of the Issue Price of the Bonds.

      (d) The amounts shown in Schedule D-1 as Qualified Costs consist only of
Project Costs paid or incurred not earlier than 60 days prior to the adoption of
the Authority's Inducement Resolution which are chargeable to the tax basis of
the Project under Section 1012 of the Code or would be so chargeable but for (or
with) a proper election by the Company.

      (e) No person who (i) was a Substantial User of the Project, or any part
or component thereof (or Related Person to such a Substantial User) within the
five-year period preceding the issuance of the Bonds, and (ii) is or will be a
Substantial User of the Project, or any part or component thereof (or a Related
Person to such a Substantial User), within the five-year period immediately
following the issuance of the Bonds has or will receive, directly or indirectly,
an amount equal to five percent or more of the Bond Proceeds for his interest in
the Project or any part or component thereof, except to the extent of any Bond
Proceeds paid as reimbursement for any Project Costs paid or incurred after the
date of the Inducement Resolution to a person who first became a Substantial
User of the Project (or Related Person to such Substantial User) no more than 60
days prior to such date.

            (f) The total amount shown in Item 5 of Schedule D-1 as Qualified
Costs (land or depreciable property) is 95% or more of the amount of Net
Proceeds of the Bonds shown in Item 4 of Schedule D-1.


                                      -18-
<PAGE>

            (g) The amount included in Qualified Costs shown in Item 5 of
Schedule D-1 as costs of "facilities directly related and ancillary to a
manufacturing facility" does not exceed 25% of the Net Proceeds of the Bonds.
"Facilities directly related and ancillary to a manufacturing facility" consist
of short-term warehousing for raw materials and finished products; laboratory
for quality control and for testing potential raw materials; loading docks; rail
spurs; fork lifts (but not delivery trucks or vans); employee parking (provided
it is free of charge and requires no parking attendants); employee restrooms,
locker rooms and eating area (but not in cafeteria or vending machines); display
area stocked with samples to show buyers (but not area staffed with sales
persons); and administrative offices for billing, receiving, inspection and
bookkeeping, provided they are not located in separate building or wing (but not
executive office space).

            (h) The amount shown in Item 5 of Schedule D-1 as cost of Land, if
any, is less than 25% of the Net Proceeds of the Bonds.

            (i) No amount shown in Item 5 of Schedule D-1 represents a cost
incurred to acquire used equipment unless such equipment was purchased with the
Net Proceeds as an integral component of an existing structure.

            (j) No part of the Net Proceeds of the Bonds is or will be used (i)
to finance inventory or for working capital or (ii) to pay any element of profit
(above actual costs incurred) to the Company or any other Principal User or any
Related Person thereto.

            (k) No amount shown in Item 5 of Schedule D-1 represents a cost
incurred to acquire an existing building unless "rehabilitation expenditures"
described in paragraph (l) are being made in the amount described in paragraph

            (l) All amounts shown in Item 5 of Schedule D-1 as "rehabilitation
expenditures" consist of costs which are chargeable to capital account, incurred
or to be incurred by the person acquiring the building or equipment (or by a
successor to such person or by the seller of the property under a sales
contract) before the date which is 2 years after the later of the date of
acquisition of the property or the date of issue of the Bonds for property in
connection with the rehabilitation of the building or equipment. In the case of
an integrated operation contained in a building before its acquisition, the term
"rehabilitation expenditures" includes the cost of rehabilitating existing
equipment in the building or replacing it with equipment having substantially
the same function. No portion of the costs listed as "rehabilitation
expenditures" represents (i) costs of


                                      -19-
<PAGE>

acquiring the property, (ii) any expenditure attributable to the enlargement of
a building, (iii) any expenditure attributable to a certified historic structure
or to a building located in a registered historic district unless either the
rehabilitation has been certified by the Secretary of the Interior or, in the
case of a building located in a registered historic district, the Secretary of
the Interior has certified that the building is not of historic significance, or
(iv) any expenditure of a lessee if, on the date the rehabilitation is
completed, the remaining term of the lease (determined without regard to renewal
periods) is less than 15 years.

            (m) The amounts shown in Item 5 of Schedule D-1 as "rehabilitation
expenditures - Existing Building," together with equity to be expended on
rehabilitation expenditures for the existing building, are 15% or more of that
portion of the cost of acquiring the building financed with Net Proceeds.

            Section 4.2. Final Disbursement. Upon the final requisition of Bond
Proceeds to pay Project Costs, the Company shall deliver to the Trustee the
following:

            (a) A schedule of the actual amount and use of Proceeds of the Bonds
substantially identical in form and substance to Schedule D-1, Use of Bond
Proceeds.

            (b) A certificate of an Authorized Representative of the Company as
to use of Proceeds of the Bonds setting forth substantially the same material as
set forth in Section 2.2 and Section 4.1 hereof.

            (c) A report of a certified public accountant to the effect that he
or she is a public accountant as defined under the Rules of Conduct of the Code
of Professional Ethics of the American Institute of Certified Public
Accountants; that they have read the Company's certificate as to use of proceeds
of the Bonds and accompanying schedule of use of proceeds of the Bonds as
referred to in (a) above; that, they have conducted an examination of such
certificate and schedule in accordance with generally accepted auditing
standards and accordingly included such tests of the accounting records and such
other auditing procedures as they considered necessary in the circumstances; and
that in their opinion the amounts shown in the schedule and the statements made
in the certificate are accurate.

            Section 4.3. Excess Proceeds Redemption. The Bonds do not have call
protection for a period longer than 10.5 years from the date hereof. Any
redemption of Bonds pursuant to Section 5.2(F) of the Indenture shall comply
with the requirements of Section 1.142-2(c) of the Income Tax Regulations and
the Bonds will be redeemed on the earliest call date or such other


                                      -20-
<PAGE>

requirements as Bond Counsel determines to be necessary to assure that interest
on the Bonds remains not includable in gross income for federal income tax
purposes.

            Section 4.4. Form 8038. The Summary of Use of Bond Proceeds (the
"8038 Schedule") annexed to Schedule D sets forth the allocation of the Sale
Proceeds to Project Costs. Said summary will be included in the Form 8038 to be
submitted by the Authority to the Internal Revenue Service.

            Section 4.5. Issuance Costs of Bonds. The Company hereby certifies
as follows in respect of the Issuance Costs of the Bonds:

            (a) The Company or a Related Person shall provide for the payment of
the portion of the Issuance Costs of the Bonds which exceeds 2% of the Issue
Price of the Bonds. This amount is not derived from the proceeds of any
obligation the interest on which is excludable from gross income for purposes of
Section 103(a) of the Code sold by a governmental unit within 15 days of the
date hereof.

            (b) The amount paid by the Company or any Related Party as a fee to
the Authority in respect of the Bonds shall be paid at the closing in an amount
equal to .50% of the original principal amount. No other fees are to be paid by
the Company or a Related Person to the Authority in respect of the Bonds.

            Section 4.6. Sale of the Project. Prior to any sale or disposition
by the Company (including the grant of a purchase option or a long term
leasehold interest) of or interest in any portion of the Project, the Company
shall furnish to the Authority a written opinion of bond counsel acceptable to
the Authority to the effect that such sale or disposition will not adversely
affect the exclusion of interest on the Bonds from gross income for federal
income tax purposes pursuant to Code Section 103(a). The foregoing shall not
apply to the sale or other disposition of personal property for cash which has
become worn out or obsolete or which is disposed of in the ordinary course of
business due to the other reasons described above, provided that the amount
received from such sale or other disposition shall be used within 6 months for
such purpose as would qualify for tax-exempt financing under Code Section
144(a).

            Section 4.7. Change in Use. The Company understands that a change in
the use of the property financed with the Net Proceeds to a use that causes any
of the representations in Article II or the certifications in Section 4.1 to be
inaccurate will result in a loss of income tax deductions for rent, interest, or
equivalent amounts paid by the person making the unqualified use, in addition to
the loss of tax exemption on bond inter-


                                      -21-
<PAGE>

est. The Company covenants that the Project will be used as set forth in Section
2.1 of this Tax Regulatory Agreement and the Net Proceeds will be spent in a
manner consistent with Sections 2.2 and 4.1 of this Tax Regulatory Agreement.
The Company agrees that in the event of post-issuance date noncompliance, as
determined in an opinion of Bond Counsel, it will use its best efforts to redeem
the Bonds at the earliest call date or establish a defeasance escrow to call
Bonds at the earliest call date.

                              AGGREGATE FACE AMOUNT

            Section 5.1. Prior Issues. The Company hereby represents that:

            (a) The aggregate face amount of the Bonds includes certain
previously issued and outstanding bonds, notes or other debts which are tax
exempt under Section 144(a) of the Code or under the predecessor Section
103(b)(6) of the Internal Revenue Code of 1954 ("Prior Issues"). The Prior
Issues included in the aggregate face amount of the Bonds are those used to
finance property:

                  (i) a Principal User of such property is also a Principal User
of the Project (or is a Related Person to a Principal User of the Project), and

                  (ii) the property financed by the Prior Issues is located in,
or is based in, the same incorporated municipality (or same county if the
Project is in an unincorporated area) as the Project, or is located in an
adjacent jurisdiction and the other property is either contiguous with the
Project or is integrated with the Project operations.

            (b) The principal amount of such outstanding Prior Issues described
in (a) above is $-0-.

            (c) The amount listed in (b) above plus the principal amount of the
Bonds is $3,810,000.

            Section 5.2. Capital Expenditures and Other Facilities.

            (a) If the amount in Section 5.1(c) above exceeds $1,000,000,
certain capital expenditures with respect to the Project and certain other
facilities are included in determining the aggregate face amount of the Bonds
for purposes of the $10,000,000 limitation in Section 144(a) of the Code. Such
expenditures must be included if paid or incurred within the six year period
beginning three years prior to the date hereof and ending three years after the
date hereof.

            (b) Capital expenditures include any amount which may be treated as
chargeable to capital account under general principles of federal income tax law
and accounting, without regard to any rule that would also permit the payor to
elect to treat such expenditures as a current expense and regardless of the
treatment actually elected. Amounts financed from the


                                      -23-
<PAGE>

principal of the Bonds or from Prior Issues are not included as capital
expenditures.

            (c) Capital expenditures for certain other facilities are included
in the determination of face amount. Such capital expenditures include those
made by any person (not just by the owner or lessee) with respect to the Project
and with respect to facilities:

                  (i) a Principal User of such facility is also a Principal User
of the Project (or is a Related Person to a Principal User of the Project), and

                  (ii) the facility is located in the same incorporated
municipality (or the same county if the Project is in an unincorporated area) as
the Project, or is located in an adjacent jurisdiction and the facility is
either contiguous with the Project or is integrated with the Project operations.

            Such facilities are "Other Facilities" for purposes of this Section.

            (d) The capital expenditures paid or incurred with respect to the
Project and with respect to the other facilities described in (c) above which
have been incurred within the three year period prior to the date hereof are in
the amount of $-0-. The Company reasonably expects that capital expenditures
with respect to the Project and such other facilities during the period three
years after the date hereof will be $50,000.

            Section 5.3. Aggregate Face Amount. The amount listed in Section
5.1(c), and the amounts listed in Section 5.2(d), equals $3,860,000.

            Section 5.4. Action Affecting Aggregate Face Amount. If at any time
during which any of the Bonds are Outstanding, the Company, any other Principal
User or Related Person proposes (a) to merge or consolidate with, acquire more
than a fifty percent (50%) interest in, or have more than a fifty percent (50%)
interest acquired by any other Person having Other Facilities located in the
Municipality; (b) to lease more than ten percent (10%) of the Project measured
by space or rental value to any other Person having Other Facilities; (c) to
enter into any contract with any Person having Other Facilities under which such
Person is entitled to take output of the Project under terms that would cause
such Person to be a Principal User of the Project; or (d) otherwise take any
action causing any Person not previously considered as a Related Person or a
Principal User to be so considered, the Company hereby covenants and agrees that
it shall first file with the Trustee and the Authority an Opinion of Counsel
satisfactory to the Trustee and the Authority to the


                                      -24-
<PAGE>

effect that such action would not cause the interest on the Bonds to be
includable in the gross income of the recipient thereof for Federal income tax
purposes.

            Section 5.5. Aggregation of Projects with Respect to Capital
Expenditures. The Company hereby covenants and agrees that it shall use its best
efforts to prohibit any Person from applying any portion of the proceeds of any
Tax-Exempt Private Activity Bond to any financing with respect to the Project or
to any single building, any shopping center or any strip of buildings sharing
substantial common facilities of which the Project is a part, without first
filing with the Trustee and the Authority, an Opinion of Counsel, satisfactory
to the Trustee and the Authority, to the effect that such action would not cause
interest on the Bonds to be includable in the gross income of the recipient
thereof for Federal income tax purposes.

            Section 5.6. Covenant. The Company covenants that it will take no
action and will permit no action to be taken which would cause the Aggregate
Face Amount of the Bonds, computed as set forth herein as of this date or any
date prior to three years from the date hereof, to exceed $10,000,000.

            Section 5.7. Violation of $10,000,000 Limit; Loss of Interest
Deduction. The Company understands that from such time as the sum of the
original aggregate face amount of the Bonds and the amount of capital
expenditures as described in Section 5.2 paid or incurred during the six year
period beginning three years before, and ending three years after, the Date of
Issue, exceeds $10,000,000, no income tax deduction will be allowed for interest
accruing on the Bonds.

                            AVERAGE MATURITY OF BONDS

      Section 6.1. Average Economic Life.

      (a) The Company represents that Schedules F1-F4 set forth the computation
of the Average Economic Life of the Project. As shown in Schedule F4, the
Average Economic Life is 38.8 years.

      (b) Computation of Average Economic Life. The Company represents in
connection with the computation of Average Economic Life as follows:

            (i) The amount shown in Item 1 of Schedule F1 is the total cost of
all assets eligible for financing under the Indenture whether or not such assets
are actually being financed with the Net Proceeds.

            (ii) Schedule F1 sets forth for each asset eligible for financing,
its cost, the ratio of asset cost to total cost and the Net Proceeds allocable
to such asset.

            (iii) Schedule F2 sets forth for each asset eligible for financing
its economic life based on Rev. Proc. 62-21 (1962-2 C.B. 418) (for real
property), the Class Life Asset Depreciation Range midpoint life as set forth in
Rev. Proc. 83-35 (for new property other than real property) or an appraisal, a
copy of which is attached to Schedule F2.

            (iv) Land is not taken into account in the computation of Average
Economic Life and has been omitted from the list in Schedule F2 because the cost
of Land represents less than 25% of the Net Proceeds.

            (v) Column E of Schedule F3 sets forth the adjusted economic life of
each asset listed in Schedule F2, taking into account the period of construction
or acquisition from the date of issue of the Bonds or the period the asset has
been placed in service before the date of issue of the Bonds.

            (vi) Column D of Schedule F4 sets forth the weighted life of each
asset calculated by multiplying the amount set forth in Column B of Schedule F4
as Net Proceeds allocable to the asset by its Adjusted Economic Life.

            (vii) The Average Economic Life is computed by dividing the total of
the weighted lives set forth in Column D of


                                      -26-
<PAGE>

Schedule F4 for all assets by the total amount set forth in Column B of Schedule
F4 as Net Proceeds allocable to the assets.

      Section 6.2. Average Maturity of the Bonds.

      (a) The Company represents that Schedule F5 sets forth the computation of
the Average Maturity of the Bonds. As shown in Schedule F5, the Average Maturity
of the Bonds is 10.511.

      (b) Computation of Average Maturity. The Company represents in connection
with the computation of the Average Maturity of the Bonds, as follows:

            (i) Column A of Schedule F5 sets forth the Issue Price of each
separate maturity of Bonds issued as part of such issues, including serial bonds
and mandatory sinking fund installments of term bonds. In the case of a single
term bond being amortized on a level debt, level principal or some other basis,
Column A sets forth the amount of principal maturing in each year.

            (ii) Column B of Schedule F5 sets forth the length of term (the
number of years carried to the first decimal point from the date of issue to the
maturity date) for each maturity of Bonds listed in Column A of Schedule F5.

            (iii) Column C of Schedule F5 sets forth the weighted maturity for
each maturity of Bonds determined by multiplying the Issue Price (Column A) by
the length of term (Column B).

            (iv) The Average Maturity of the Bonds is computed by dividing the
total of the weighted maturities shown in Column C of Schedule F5, by the total
of the Issue Price (Column A).

      (c) 120 Percent Rule. Based on the representations described above, the
Average Maturity of the Bonds does not exceed 120 percent of the Average
Economic Life of the Project.

      Section 7.1. Composite Issues.

      (a) Company Representation. The Company represents that no state or
political subdivision thereof, or entity acting on behalf of any state or
political subdivision, has sold any other Tax-Exempt Private Activity Bonds in
the 15 day period preceding the date of sale of the Bonds the proceeds of which
were or are to be used in whole or in part, directly or indirectly, for the
benefit of the Company, any other Principal User of the Project or any Related
Person and that no state or political subdivision thereof, or any entity acting
on behalf of any state or political subdivision, will sell any other Tax-Exempt
Private Activity Bonds in the 15 day period following the date of sale of the

      (b) Date of Sale of Variable Rate Obligations. For purposes of Section
7.1(a), the date of sale of Variable Rate Obligations (such as the Bonds) is the
date of sale of such obligations.

      Section 7.2. Federal Guarantees.

      (a) The Company represents that the United States (or any agency or
instrumentality thereof) will not guarantee (in whole or in part), directly or
indirectly, the payment of principal or interest on the Bonds within the meaning
of Section 149(b) of the Code, and will not lease any portion of the Project.

      (b) Other than amounts invested pending use to pay Project Costs or in a
reasonably required reserve fund, if any, none of the Net Proceeds of the Bonds
will be (a) used to make loans or other investments the payments on which are
guaranteed, in whole or in part, by the United States (or any agency or
instrumentality thereof) or (b) invested, directly or indirectly, in deposits or
accounts in a federally insured financial institution within the meaning of
Section 149(b) of the Code.

      (a) Responsibilities of Parties.

            (i) Company. The Authority and the Company acknowledge that the
continued exclusion from federal gross income of interest on the Bonds depends,
in part, upon compliance with the rebate requirement of Section 148(f) of the
Code. The Authority authorizes the Company to take any action necessary to
comply with this requirement. The Company hereby agrees and covenants that it
shall do and perform all acts and things necessary, to the extent such actions
are within the control of the Company, in order to assure that the rebate
requirement of Section 148(f) of the Code is met. To that end, the Company, on
behalf of the Authority, shall take the actions described in Section 8.3.


                                      -29-

            (ii) Trustee. The Trustee shall furnish the investment information
and make the transfers, dispositions and payments required by this Section 8.3
and Section 5.6 of the Indenture upon receipt of proper direction by the
Company. The Trustee shall be deemed conclusively to have complied with the
provisions of this Section 8.3 and Section 5.6 of the Indenture if it follows
the directions made to it by or on behalf of the Company pursuant to this
Section 8.3, including supplying all necessary information. The Trustee shall
have no obligation to rebate any amounts required to be rebated to the federal
government pursuant to this Section 8.3, other than from moneys held in the
funds or accounts created under the Indenture or from other funds provided it by
the Authority or the Company. The Trustee shall be fully protected in acting on
any determination made by the Company or its Rebate Agent regarding rebate
payments of any kind or contained in any certificate and shall not be liable or
responsible in any manner, except for gross negligence or wilful misconduct, to
any person so acting, notwithstanding any error in such determination. The
Trustee shall not be responsible or liable to the Authority or the Company, or
any other party, for the failure of the Authority or the Company to comply with
the provisions of this Section 8.3 or Section 5.6 of the Indenture and shall
have no obligation to notify the Company of its failure to so comply.
Notwithstanding any other provision herein or in any supplement hereto, the
Trustee shall have no responsibility or liability as to the accuracy of the
representations of the Authority or the Company herein or in any supplement
hereto or as to compliance by the Authority or the Company with the covenants
and agreements of the Authority and the Company herein or in any supplement
hereto.

            (iii) Cooperation of Authority. The Authority covenants and agrees
that it shall do and perform all acts and things necessary, to the extent such
actions are within the control of the Authority, in order to assure that the
rebate requirement of Section 148 is met in respect of the Bonds. Upon request
of the Company or the Trustee, the Authority agrees to render all reasonable
cooperation and assistance as may be required to carry out the provisions of
this Section 8.3 and Section 5.6 of the Indenture, such cooperation to include
the Authority's authorization of the Company to communicate with the Internal
Revenue Service on behalf of the Authority and in respect of the rebate
requirement of Code Section 148(f) as applied to the Bonds and any related
administrative or judicial proceedings.

            (iv) Company's Indemnification of Authority and Trustee. The Company
shall be liable and shall indemnify and hold the Authority and the Trustee
harmless against liability for any and all payments due to the United States
pursuant to Section 148(f) of the Code. Further, the Company agrees that the
Authority and the Trustee shall not be held liable for any mistake or


                                      -30-
<PAGE>

error, other than, in the case of the Trustee, an act of gross negligence or
wilful misconduct, in the filing of the payment or the determination of the
amount due the United States or the providing of information necessary for such
determination, resulting in any consequence other than liability for payments
due to the United States.

      (b) Exceptions from Rebate Requirement

            (i) General. Each of the following exceptions from the rebate
requirement operates independently. Gross Proceeds may qualify for one exception
without regard to whether another of the exceptions is also available. If an
exception is applicable, the Company may nevertheless choose not to use the
exception, except in the case of Section 8.3(b)(v).

            (ii) Six Month Exception. The rebate requirement does not apply if
95% of the Gross Proceeds (other than certain types of Gross Proceeds described
below) are spent for the Project within six months of the Date of Issue and 100%
within one year. The Gross Proceeds not eligible for this exception, and thus
subject to the rebate requirement (unless another exception applies), are:
amounts in a Bona Fide Debt Service Fund, amounts in a reasonably required
reserve fund (including amounts in any collateral fund for a credit facility),
Gross Proceeds arising after the six month period that were not reasonably
expected as the Date of Issue, and payments on the Loan Agreement. The exception
will not apply if on the Date of Issue Gross Proceeds are reasonably expected to
arise after the six month period.

            (iii) Eighteen Month Exception. The rebate requirement does not
apply if all of the Gross Proceeds (other than certain types of Gross Proceeds
described below) are spent for the Governmental Purpose in accordance with the
following schedule: at least 15% within the 6 months from the Date of Issue, at
least 60% within 12 months of the Date of Issue, and 100% within 18 months of
the Date of Issue, except that a reasonable retainage (not to exceed 5% of such
Gross Proceeds) to promote performance or to cover disputes need not be expended
until 30 months after the Date of Issue. Also, failure to satisfy the third
spending requirement is disregarded if the Company exercises due diligence to
complete the Project and the amount of the failure does not exceed the lesser of
3% of the Issue Price or $250,000. To determine compliance with the first two
spending periods, the amounts of Investment Proceeds included in Gross Proceeds
is the amount estimated as of the Date of Issue. The Gross Proceeds not eligible
for this exception and thus subject to the rebate requirement (unless another
exception applies) are: amount in a Bona Fide Debt Service Fund, amount in a
reasonably required reserve fund (including amounts in any collateral fund for a
credit facility), Gross Proceeds arising more


                                      -31-
<PAGE>

than 18 months after the Date of Issue that were not reasonably expected as of
the Date of Issue; and payments on the Loan.

            (iv) Project Purpose. In applying Sections 8.3(b)(ii) and (iii), the
Project includes payments of interest, but not principal, on the Bonds.

            (v) Bona Fide Debt Service Fund Exception. Any amount earned on a
Bona Fide Debt Service Fund for a Bond Year shall not be subject to the Rebate
Requirement if the gross earnings on such fund for such year is less than
$100,000. Gross earnings shall be deemed to be less than $100,000, if the
average annual debt service on the Bonds is less than $2,500,000.

      (c) Investment Information Requirements.

            (i) Investment Information to be obtained from the Trustee. The
Company shall obtain from the Trustee the following information:

                  (A) the date upon which each Investment is purchased with
            amounts in funds and accounts under the Indenture;

                  (B) the purchase price of each Investment (net of commissions,
            administrative expenses and similar expenses);

                  (C) the date of sale or maturity of each Investment;

                  (D) the proceeds received on the sale or maturity of each
            Investment (recording separately commissions, administrative
            expenses and similar expenses to the extent such information is
            obtainable with a good faith effort); and

                  (E) earnings received with respect to each Investment.

            The Trustee agrees to supply the foregoing information not later
than 20 days after the end of each Bond Year.

            (ii) Investment Information Requirements Applicable to the Company.
The Company will maintain records adequate to determine the Rebate Requirement.
Such records will include, but are not necessarily limited to, information
regarding the following with respect to each and every Nonpurpose Investment by
the Company allocated to Gross Proceeds:


                                      -32-
<PAGE>

            (A) the date of expenditure of all amounts held in the funds and
      accounts under the Loan Agreement and Indenture and

            (B) with respect to each Investment held in the funds or accounts
      under the Indenture:

                  (1) the purchase price (recording separately commissions,
            administrative expenses and similar expenses);

                  (2) nominal rate of interest;

                  (3) amount of accrued interest (included in purchase price)

                  (4) par or face amount;

                  (5) purchase date;

                  (6) maturity date;

                  (7) amount of original issue discount or premium (if any);

                  (8) type of Investment;

                  (9) frequency of periodic payments;

                  (10) period of compounding;

                  (11) yield to maturity;

                  (12) date of disposition;

                  (13) amount realized on the disposition (including accrued
            interest) recording separately commissions, administrative expenses
            and similar expenses)

                  (14) market price data sufficient to establish that the
            purchase price was equal to the fair market value on the date of
            acquisition or, if earlier, on the date of a binding contract to
            acquire such Investment; and

                  (15) market price data sufficient to establish the fair market
            value of any Investment as of any Computation Date, and as of the
            date such Investment becomes allocable to, is sold, or otherwise
            ceases to be allocable to, Gross Proceeds.


                                      -33-
<PAGE>

      (d) Record-Keeping Obligation. The Company shall retain such information,
together with the records described in Section 8.3(c)(i) hereof and the records
of the determinations required by Section 8.3 hereof until six years after the
Final Computation Date or for such other period as the Treasury Department may,
by regulations or rulings, provide.

      In the event, as a result of a failure of the Company to provide
directions, the Trustee invests amounts held under the Indenture without
direction from the Company, the Trustee shall retain with respect to such
investments documentation to establish that all such investments have been
acquired and disposed of in arms'-length transactions at prices equal to their
Fair Market Value. In particular, the Trustee shall retain evidence to show that
the requirements relating to the specific investments described in Section
8.3(e)(i)(C) and Section 8.3(e)(i)(D) have been met. For United States Treasury
obligations purchased directly from the Treasury, proof of the price paid
therefor shall be sufficient evidence.

      (e) Investment Valuation Rules.

            (i) In General. The Company agrees to comply with the following
provisions and procedures in respect of the acquisition and disposition of
Nonpurpose Investments. In this regard, the Company agrees, among other things,
that it will not acquire or cause to be acquired any Nonpurpose Investment
acquired with Gross Proceeds for an amount in excess of its Fair Market Value or
sell or otherwise dispose of any such Nonpurpose Investment for an amount less
than its Fair Market Value.

            (A) The Fair Market Value of any Nonpurpose Investment for which
      there is an Established Securities Market shall be determined as provided
      below. Except as otherwise provided below, any market especially
      established to provide a Nonpurpose Investment to an issuer of municipal
      obligations shall not be treated as an established market. Any investment
      not of a type traded on an Established Securities Market is rebuttably
      presumed to be acquired or disposed of for a price that is not equal to
      its Fair Market Value, except for the safe harbors set forth in paragraphs
      3 and 4 hereof.

            (B) The Fair Market Value of any Nonpurpose Investment for which
      there is an Established Securities Market shall mean the price at which a
      willing buyer would purchase the investment from a willing seller in a
      bona fide arms'-length transaction determined on the date on which the
      contract to purchase or sell becomes binding (i.e. the trade date).


                                      -34-
<PAGE>

            If a United States Treasury obligation is acquired directly from or
      disposed of directly to the United States Treasury, such acquisition or
      disposition shall be treated as establishing a market for the obligation
      and as establishing the Fair Market Value of the obligation.

            (C) In the case of a certificate of deposit issued by a commercial
      bank which has a fixed interest rate, a fixed principal payment schedule,
      and a substantial penalty for early withdrawal, the certificate of deposit
      shall be considered acquired or disposed of for an amount equal to the
      Fair Market Value of the certificate of deposit if the certificate of
      deposit has a yield not less than the yield on reasonably comparable
      direct obligations of the United States and the yield on the certificate
      of deposit is not less than the highest yield that is published or posted
      by the provider to be currently available from the provider on comparable
      certificates of deposit offered to the public (See Schedule J for the
      certification).

            (D) In the case of a Guaranteed Investment Contract, the obligations
      acquired thereunder shall be considered acquired or disposed of for an
      amount equal to the Fair Market Value of such obligations if:

                        (1) the purchaser makes a bona fide solicitation for a
            Guaranteed Investment Contract with specified material terms and
            receives at least three bids on the contract from persons other than
            those with an interest in the Bonds (e.g., underwriters or brokers);

                        (2) the purchaser purchases the highest yielding
            investment contract for which a qualified bid is made (determined
            net of broker's fees);

                        (3) the determination of the price of the Guaranteed
            Investment Contract takes into account as significant factors, the
            purchaser's reasonably expected draw-down schedule for the funds to
            be invested, exclusive of float funds and reasonably required
            reserve or replacement funds;

                        (4) the collateral security requirements and other terms
            for the Guaranteed Investment Contract are reasonable, based on all
            the facts and circumstances;

                        (5) the provider of the Guaranteed Investment Contract
            certifies those administrative costs that are reasonably expected to
            be paid to third parties in connection with the contract (see
            Schedule I); and


                                      -35-
<PAGE>

                        (6) the yield on the Guaranteed Investment Contract
            (determined net of brokers' fees) is not less than the yield
            currently available from the provider on reasonably comparable
            contracts offered by the provider to other persons, if any, from a
            source of funds other than gross proceeds of an issue of tax-exempt
            bonds.

      (f) Computation of Bond Yield; Variable Yield Issue.

            (i) General. When the Bonds are a Variable Yield Issue, the Bond
Yield is computed separately for each Computation Period and means the Yield
that produces, as of the first day of the Computation Period, a Present Value of
all payments made on the Bonds attributable to the Computation Period equal to
the Present Value of all prices received for the Bonds during such period.

            (ii) Bond Payments. Payments on the Bonds attributable to a
Computation Period are:

                  (A) the Purchase Price of Bonds actually tendered for by
Bondholders for purchase during such period, the Redemption Prices (or, if
greater, Value) of the Bonds actually redeemed during such period and the
principal of the Bonds coming due during such period;

                  (B) payments during such period for Bond interest that accrued
during such period or that accrued during the preceding Computation Period and
was included in the Value of a Bond outstanding at the end of such preceding
period;

                  (C) the Value of the Bonds outstanding on the last day of such
period; and

                  (D) amounts properly allocable to fees for a Qualified
Guarantee of the Bonds for such period.

            (iii) Bond Prices. Prices received for the Bonds attributable to the
Computation Period are:

                  (A) in the case of the first day of the first Computation
Period (i.e., the Date of Issue), the Issue Price of the Bonds; and in the case
of the first day of each succeeding Computation Period, the Value of the Bonds
outstanding as of the last day of the preceding Computation Period; and

                  (B) the Purchase Prices of Bonds paid by buyers in a
remarketing of the Bonds which occurs during the period.

            (iv) Fixed Yield Bonds Included in a Variable Yield Issue. If, when
the Bonds are Variable Yield Issue, some of the


                                      -36-
<PAGE>

Bonds are Fixed Yield Bonds, the Bond Yield shall be computed pursuant to this
Section 8.3(f); however, the special rules set forth in Section 8.3(g)(iii) for
certain Fixed Yield Bonds shall apply to determine Bond payments and Bond prices
in respect of such Bonds in a Computation Period.

            (g) Computation of Bond Yield: Fixed Yield Issue.

                  (i) General. When the Bonds are a Fixed Yield Issue, the Bond
Yield shall be the Yield that produces, as of the Conversion Date, a Present
Value of all unconditionally payable payments of principal and interest paid
after such date and fees for a Qualified Guarantee properly allocable to the
period after such date equal to the Value of the Bonds outstanding on such date.

                  (ii) Mandatory Sinking Fund Redemption. In determining Bond
Yield, Bonds of the same maturity subject to the same mandatory sinking fund
redemption schedule shall be treated as redeemed in accordance with the
redemption schedule for an amount equal to their Present Value, unless the
Stated Redemption Price at maturity of such Bonds does not exceed the Value of
the Bonds at the Conversion Date by 1/4% times the product of the Stated
Redemption Price at maturity and the number of years to the weighted average
maturity date of the Bonds subject to the same redemption schedule, in which
case the Bonds are treated as redeemed at their outstanding principal amount
plus accrued, unpaid interest.

                  (iii) Optional Early Redemption. In determining Bond Yield,
certain Bonds subject to optional early redemption shall be treated as redeemed
for their Stated Redemption Price on the optional redemption date that produces
the lowest Bond Yield. This rule applies to Bonds subject to optional redemption
if (1) the first optional redemption date is within 5 years of the Conversion
Date and the Bond Yield (assuming no optional redemptions occur) is .125%
greater than the Bond Yield (assuming all Bonds optionally redeemable within 5
years of the Conversion Date are redeemed at their earliest redemption date);
(2) the Value of the Bonds exceeds their Stated Redemption Price at Maturity by
more than the product of 1/4% and the number of complete years to the first
optional redemption date of the Bonds; or (3) the Bonds bear interest at
increasing interest rates (i.e. stepped coupon bond).

                  (iv) No Recomputation of Bond Yield. The Bond Yield of a Fixed
Yield Issue shall be computed as of the Conversion Date and shall not be
recomputed unless the Authority transfers, waives, modifies, or engages in a
similar transaction regarding any right that is part of the terms of a Bond or
is otherwise associated with the Bond (e.g., a redemption right) in


                                      -37-
<PAGE>

a transaction separate and apart from the event that causes the Bonds to be a
Fixed Yield Issue. If such a transfer, waiver, etc., occurs the Bond Yield shall
be recomputed as if the Bonds were retired and reissued on the date of such
occurrence for a price equal to the Value of the Bonds on such date and the
recomputed Bond Yield shall take into account any amounts received by the
Authority or the Company or a Related Person to the foregoing as consideration
for the transfer, waiver, etc.

            (h) Allocation of Qualified Guarantee Payments.

                  (A) General. Payments for a Qualified Guarantee must be
allocated to Bonds and Computation Periods in a manner properly reflecting the
proportionate credit risk to the guarantor.

                  (B) Initial Fees. Reasonable credit facility set-up fees may
be allocated ratably during the initial term of the credit facility.

                  (C) Variable Yield Bonds.

                        (1) If a Variable Yield Bond is redeemed early, the fees
otherwise allocable to the period after redemption are allocable to Bonds that
remain outstanding, or, if none, the period before the redemption.

                        (2) Non-level fees for a Qualified Guarantee for
Variable Yield Bonds are properly allocated if, after each Bond Year the
guarantee is in effect, an equal amount (proportionately reduced for any short
Bond Year) is treated as paid at the beginning of that Bond Year. The Present
Value (computed using a discount rate equal to the yield on the guaranteed Bonds
determined without regard for the non-level payments) of the annual amounts must
equal the fee for the guarantee allocated to that Bond.

      (i) Hedge. Neither the Authority nor the Company nor any Related Person to
the foregoing has entered into, or expects to enter into a hedge in respect of
the Bonds. In the event a hedge is entered into for the Bonds, the Authority and
the Company covenant to consult with Bond Counsel as to the computation of Bond
Yield.

      (j) Rebatable Arbitrage.

            (i) Frequency of Calculation; Rebate Exceptions. Rebatable Arbitrage
shall be calculated as of each Computation Date and as of the last day of each
Bond Year. However, see Section 8.3(b) above for instances in which Rebatable
Arbitrage need not be computed in respect of certain Gross Proceeds.


                                      -38-
<PAGE>

            (ii) Special Rule for End of Bond Year Calculations. When the Bonds
are a Variable Yield Issue, Rebatable Arbitrage shall be calculated as of the
last day of a Bond Year based on a Bond Yield determined in a manner similar to
the method of determination set forth in Section 8.3(f), using the Bond Year as
the period of computation. Calculations performed at the end of a Bond Year are
performed solely for determining the deposits to the Rebate Fund and do not
affect the calculation of the Rebatable Arbitrage on each Computation Date.

            (iii) Receipts. Receipts with respect to a Nonpurpose Investment
include all constructive as well as all actual receipts with respect to such
investment. Constructive receipts include (1) in the case of a Nonpurpose
Investment that is allocated to Gross Proceeds as of the last day of the
Computation Period (or as of the last day of the Bond Year), the Value of the
Nonpurpose Investment on such date and (2) in the case of a Nonpurpose
Investment that ceases to be allocated to Gross Proceeds before its disposition
or redemption (e.g., the investment becomes allocable to transferred proceeds of
another issue or ceases to be allocated to the issue by operation of the
Universal Cap) the Value of the Nonpurpose Investment on the date it ceases to
be allocated to the issue. Receipts in respect of a Nonpurpose Investment are
reduced by reasonable direct Administrative Costs (see paragraph (v) below).
Receipts in respect of Investments do not include recoveries of overpayments of
rebate.

            (iv) Payments. Payments with respect to a Nonpurpose Investment
include all amounts of Gross Proceeds directly used to purchase such Nonpurpose
Investment, adjusted for direct Administrative Costs. Where a Nonpurpose
Investment is allocated to Gross Proceeds but was not directly purchased with
Gross Proceeds, there shall be treated as a payment in respect of such
investment the Value of such investment on the date it is allocated to Gross
Proceeds. For a Nonpurpose Investment allocated to an issue at the end of the
Computation Period (or at the end of the Bond Year), the Value of that
investment on the first day of the next Computation Period (or on the first day
of the next Bond Year) shall be treated as a payment. Payments in respect of
Nonpurpose Investments include the Computation Credit and any Yield Reduction
Payments made on Nonpurpose Investments.

            (v) Reasonable, direct and indirect Administrative Costs may be
taken into account with respect to investments of Gross Proceeds in both
regulated investment companies (within the meaning of Section 67(c)(2)(b) of the
Code) and in a Commingled Fund in which the Authority and the Company and all
members of the same controlled group as the Authority or the Company own less
than 10% of the beneficial interest in the investments of the Commingled Fund.
For purposes of regulated investment companies and Commingled Funds only,
"administrative costs"


                                      -39-
<PAGE>

include costs paid by or on behalf of an issuer for brokerage or selling
commissions, legal and accounting fees, investment advisory fees, recordkeeping,
safekeeping, custody, and similar costs and expenses of a fund as well as
indirect costs such as general overhead. Administrative Costs also include
12(b)-1 fees charged by a regulated investment company.

            Administrative Costs for other investments include a brokerage
commission for an investment contract purchased with Gross Proceeds regardless
of whether the brokerage commission is paid or incurred on behalf of the
Authority or the provider of the investment contract. Whether the administrative
costs are reasonable is based on all the facts and circumstances including,
without limitation, whether or not comparable in nature and amount to customary
administrative costs that would be charged for the same investment if the
investment were made from a source of funds other than Gross Proceeds. See
Section 1.148-5T(e) (2)(iii) of the Temporary Treasury Regulations for the
special rule for administrative costs of a Guaranteed Investment Contract.

            Under no circumstances, however, may administrative costs paid or
incurred for computing Rebateable Arbitrage be taken into account.

            (vi) Future Value Formula. The future value of a receipt or payment
in respect of a Nonpurpose Investment shall be determined by using the following
formula:

                                  FV=PV(1 + i)^n
      where:

      FV = the future value of the receipt or payment;

      PV = the amount of the receipt or payment;

      i  = Bond Yield divided by the number of compounding
           intervals in a year; and

      n  = the number of whole or fractional compounding intervals from the
           date of the receipt or payment to the last day of a Bond Year or the
           Computation Period.

            (vii) Maintenance of Rebate Requirement in the Rebate Fund; Deposits
and Withdrawals from Rebate Fund. There shall be maintained in the Rebate Fund
an amount equal to the Rebatable Arbitrage for the Bonds determined from time to
time as of each date of calculation of the Rebatable Arbitrage. If the Rebatable
Arbitrage as so determined exceeds the amount on deposit in the Rebate Fund,
then within 60 days of such calculation date, the Company shall transfer from
its own funds (or the Company shall


                                      -40-
<PAGE>

direct the Trustee to withdraw from the funds and accounts held under the
Indenture and transfer) to the Rebate Fund an amount such that the balance in
the Rebate Fund after such transfer equals the Rebatable Arbitrage as of such
date of calculation. If the amount on deposit in the Rebate Fund exceeds the
Rebatable Arbitrage as so determined, the Trustee, upon written direction of the
Company, shall withdraw such excess amount and transfer such amount as provided
in the Indenture. Any amounts remaining in the Rebate Fund after payment with
respect to all the Bonds and payment of the amounts described in subsection (ix)
of this Section 8.3(j), or provision made therefor satisfactory to the Trustee,
including accrued interest and payment of any applicable fees to the Trustee and
satisfaction of the requirements of this Section 8.3(j), shall be withdrawn by
the Trustee and paid to the Company upon written direction of the Company. The
Company covenants to make deposits to the Rebate Fund in the event the amounts
in the Rebate Fund and transfers of the available amounts from the funds and
accounts under the Indenture are insufficient to meet the Rebatable Arbitrage
requirement on the end of any Bond Year or any Computation Date.

            (viii) Withdrawals to Pay United States. Within 60 days after each
Computation Date, the Company shall direct the Trustee to make any required
rebate payments related to such date to the United States. The rebate payment as
of any Installment Computation Date shall be an amount which, when added to the
future value of previous rebate payments, equals at least 90% of the Rebatable
Arbitrage calculated as of such Computation Date. The rebate payment as of the
Final Computation Date shall be an amount, which when added to the future value
of all previous rebate payments, equals 100% of the Rebatable Arbitrage
calculated as of such Final Computation Date.

            (ix) Place and Manner of Rebate Payments. Each rebate payment shall
be made to the Internal Revenue Service Center, Philadelphia, Pennsylvania 19255
on or before the date such payment is due and shall be accompanied by IRS Form
8038-T.

      (k) Survival of Defeasance or Payment. Notwithstanding anything in this
Tax Regulatory Agreement or the Indenture to the contrary, the obligation of the
Authority and the Company to remit the amount determined pursuant to section 8.3
to the Internal Revenue Service, and to comply with all other requirements
contained in this Section 8.3, shall survive the defeasance or payment in full
of the Bonds.

      Section 8.4. Non-Arbitrage Certifications of the Authority. The Authority
hereby certifies that:

      (a) Authorized Officer. The undersigned officer of the Authority is a duly
chosen, qualified official of the Authority,


                                      -41-
<PAGE>

and as such is charged, together with other officials, with the responsibility
for issuing the Bonds. The undersigned officer of the Authority is familiar with
the facts, estimates and expectations of the Authority set forth herein and is
duly authorized to deliver the certifications contained in this Section 8.4 on
behalf of the Authority.

      (b) Authorization and Purpose. The Bonds are being issued pursuant to the
Act and the Indenture for the purpose of providing funds to pay a portion of the
Project Costs and Costs of Issuance.

      (c) Facts, Estimates and Circumstances. On the basis of the facts,
estimates and circumstances in existence on the date hereof, the undersigned
officer of the Authority reasonably expects the following with respect to the
amount and use of proceeds of the Bonds and certain other funds.

      (i) Proceeds.

            (A) Sale Proceeds.

                  (1) Total. The Bonds are being delivered on this day to the
                  initial purchaser in exchange for Sale Proceeds of $3,810,000.
                  Such amount is calculated as the principal amount of the Bonds
                  ($3,810,000) plus accrued interest, if any, and minus
                  underwriter's discount, if any.

                  (2) Accrued Interest. The amount of Proceeds received as
                  accrued interest on the Bonds (i.e., $-0-) will be deposited
                  in the Debt Service Fund and will be used to pay a portion of
                  the interest on the Bonds on the next interest payment date.

                  (3) Project Fund. $3,810,000 of the proceeds of the Bonds will
                  be deposited in the Project Fund which will be used to pay the
                  costs of the Project including costs of issuance in the amount
                  of $47,768.

                  (4) Capitalized Interest. Proceeds in the amount of $112,488
                  will be deposited in the Project Fund to pay a portion of the
                  interest during the acquisition, construction and installation
                  of the Project.

                  (5) Binding Obligations. An amount greater than 5% of the net
                  sale proceeds has been expended on the Project.


                                      -42-
<PAGE>

                  (6) Due Diligence. Work on the Project will proceed with due
                  diligence.

                  (7) Expenditure. A portion of the proceeds and Investment
                  Proceeds in the Project Fund are expected to pay Project Costs
                  before December 12, 2000. A portion of the proceeds may be
                  used to reimburse costs incurred by the Company prior to the
                  date of issue of the Bonds. No proceeds will be used to
                  reimburse expenditures made earlier than 60 days prior to date
                  of the Inducement Resolution.

            (ii) Investment Proceeds. The Investment Proceeds of the Bonds
      derived from Bond proceeds in the funds held under the Indenture, will be
      deposited to the Earnings Fund and after any transfers to the Rebate Fund,
      credited to the Project Fund prior to the Completion Date. After the
      Completion Date, the earnings on such funds will be credited first to the
      Earnings Fund and Rebate Fund, if necessary, and then applied to pay debt
      service on the Bonds. Earnings on all funds and accounts will be deposited
      in the Rebate Fund to the extent required by the Indenture and this Tax
      Regulatory Agreement.

            (iii) No Overissuance. The Net Proceeds and Investment Proceeds of
      the Bonds do not exceed the amount necessary to pay the costs of the
      Project, to pay accrued interest and interest on the Bonds, and to pay the
      Costs of Issuance of the Bonds.

      (d) Debt Service. The Authority expects that debt service on the Bonds
will be paid from payments of principal and interest under the Loan Agreement,
amounts transferred to the Debt Service Fund as accrued interest and earnings on
amounts in the Debt Service Fund. Payments of principal and interest shall be
paid to the Trustee for deposit in the Debt Service Fund. Amounts so deposited
in the Debt Service Fund (other than prepayments, which shall be used for the
optional redemption of Bonds) will be applied (i) on the next Interest Payment
Date to pay interest then due on the Bonds, principal of the Bonds, at maturity
or upon redemption prior to maturity and (ii) to pay the Trustee's annual fee.

      The Debt Service Fund (other than any carryover amount exceeding
one-twelfth of annual debt service) will be used primarily to properly match
payments of interest and principal on the Loan Agreement with debt service
payments on the Bonds in each Bond Year and the Authority expects that such
account and fund will be depleted at least once a year, except possibly for any
capitalization interest account and a carryover amount which


                                      -43-
<PAGE>

will not exceed one year's earnings on such account and fund or, in the
aggregate, one-twelfth of the debt service on the Bonds for the immediately
preceding Bond Year. Optional prepayments are not anticipated, but if made, they
will be deposited in the Debt Service Fund and it is expected that they will be
expended to redeem Bonds on the earliest available date for redemption.

      Earnings from amounts in the Debt Service Fund will be deposited in the
Earnings Fund and after provision for rebate, if any, to the Debt Service Fund
and applied for the purposes thereof.

      (e) Renewal Fund. No renewal fund has been created for the Project.

      (f) Earnings and Rebate Funds. Amounts will be transferred to the Earnings
Fund and the Rebate Fund pursuant to section 5.7(B) of the Indenture and this
Tax Regulatory Agreement. Amounts in the Rebate Fund shall be paid to the United
States in the amounts and at the times set forth in this Tax Regulatory
Agreement, or to the extent remaining after final payment of the Rebate
Requirement, shall be remitted to the Company.

      (g) No Other Sinking Funds or Funds Pledged with Reasonable Assurance of
Availability for Debt Service. Except for the Debt Service Fund, no other funds
have been created by the Authority or the Company as to which amounts deposited
therein are reasonably expected to be used directly or indirectly to pay debt
service on the Bonds or which directly or indirectly secure the Bonds and for
which there is a reasonable assurance that amounts therein will be available to
pay debt service on the Bonds in the event financial difficulties are
encountered.

      (h) No Replacement. No portion of the Bond Proceeds will be used as a
substitute for other funds of the Authority or the Company (i) which were
otherwise to be used to pay the cost of the Project, (ii) which will not be so
used, and (iii) which have been or will be so used to acquire directly or
indirectly, Investments producing a Yield in excess of the Yield on the Bonds.

      (i) Yield on the Bonds.

            (i) General. For purposes of this Tax Regulatory Agreement, Yield on
      the Bonds means that percentage rate which, when used in computing (by the
      actuarial method using semi-annual compounding) the present value of all
      payments of interest on and principal of Bonds and of all Qualified
      Guarantee Payments, if any, produces an amount equal to the


                                      -44-
<PAGE>

      Issue Price of the Bonds. Because the interest rate on the Bonds to
      maturity is not determinable on the date hereof, the yield to maturity
      cannot be determined on the date hereof.

      (j) Yield on the Loan Agreement.

            (i) General. Pursuant to the terms and limitations of the Loan
      Agreement, the Company has promised to pay the principal and interest on
      the Bonds. The Yield on the loan is calculated as the percentage rate
      which, when used in computing (by the actuarial method and using
      semi-annual compounding) the present value of all scheduled and expected
      payments and of certain fees paid to the Authority, produces an amount
      equal to the adjusted purchase price of the loan. The purchase price of
      the loan shall be equal to the Issue Price of the Bonds. Calculated in
      such manner, Bond Counsel, based on the calculations of Brown Brothers
      Harriman & Co., has advised the Authority that the Yield on the loan will
      not exceed the Yield on the Bonds by more than .125 percent.

      (k) Yield on the Investments Other Than Loan Agreement.

            (i) Accrued Interest. The amount of Proceeds received as accrued
      interest, if any, will be invested without Yield restriction until used on
      the next interest payment date to pay a portion of the interest then due
      on the Bonds.

            (ii) Project Fund. Amounts on deposit in the Project Fund (including
      capitalized interest) may be invested without regard to Yield restriction
      until the earlier of the date of expenditure of such amounts or the date
      three years from the date hereof.

            (iii) Investment Proceeds. Investment Proceeds will be invested
      without restriction as to Yield for one year from the date of receipt of
      the amount earned.

            (iv) Debt Service Fund (Other Than Excess Carryover Amounts).
      Amounts in the Debt Service Fund (other than carryover amounts exceeding
      one-twelfth of debt service on the Bonds for the immediately preceding
      Bond Year and other than any capitalized interest account) will be
      invested without Yield restriction for a period not exceeding thirteen
      months from the date of deposit of such amounts in such fund. Carryover
      amounts in the Debt Service Fund exceeding one-twelfth of debt service on
      the Bonds for the immediately preceding Bond Year (other than any
      capitalized interest account) will be invested, at a yield not exceeding


                                      -45-
<PAGE>

      the Yield on the Bonds, in Tax Exempt Investments or will be the subject
      of Yield Reduction Payments as described in section 8.7 hereof.

            (v) Rebate Fund. Amounts deposited in the Rebate Fund which are
      Investment Proceeds and other amounts in the Rebate Fund will be invested
      without Yield limitation while they are held in the Rebate Fund.

            (vi) Yield Limitation. Amounts referenced above as subject to a
      three year, one year, or 13 month period of investment which remain
      unexpended at the end of such period, will be invested at a Yield not
      exceeding the Yield on the Bonds, in Tax-Exempt Investments or will be the
      subject of Yield Reduction Payments to the extent that such amounts in the
      aggregate (with other Yield-restricted amounts) exceeds $100,000, unless a
      ruling of the Internal Revenue Service, or an Opinion of Counsel, is first
      obtained to the effect that no such Yield restriction is necessary.
      Notwithstanding the foregoing, no Yield restriction shall apply to any
      Nonpurpose Investment not allocated to the Bonds pursuant to Section 8.6.

            (vii) Valuation of Investments. In determining the amounts on
      deposit in any account for purposes of this Section 8.5(o), the purchase
      price of Investments, including accrued interest, shall be added together,
      and there shall be added to or subtracted from such purchase price any
      discount or premium computed ratably on an annual basis.

      (l) Bonds Not Hedge Bonds. At least eighty-five percent (85%) of the Net
Proceeds of the Bonds will be expended within three years of the date hereof and
no amount of the Net Proceeds or Investment Proceeds is or will be invested in
either Nonpurpose Investments or Tax-Exempt Investments, having a guaranteed
yield for 4 years or more.

      (m) Reliance Upon Certification, Advice and Computations. The Authority's
certifications contained in Section 8.4(c)(iii) No Overissuance, Section 8.4(g)
No Other Sinking Funds or Funds Pledged with Reasonable Assurance of
Availability for Debt Service, and Section 8.4(h) No Replacement are made in
reliance upon the Non-Arbitrage Certifications of the Company contained in
Section 8.7. The Authority's certification as to the Yield on the loan has been
made in reliance on the advice of Bond Counsel and calculation by Brown Brothers
Harriman & Co. The Authority is not aware of any facts or circumstances that
would cause it to question the accuracy of such certifications, representations,
computations and advice.


                                      -46-
<PAGE>

      (n) Hedging Transactions. The Company has not entered into, nor does it
expect to enter into, any "hedging" transactions (i.e. transactions involving
interest rate swaps, caps, collars, or similar mechanisms to shift interest rate
risk) in respect of the Bonds or the loan. If the Company does enter into a
"hedging" transaction in respect of the Bonds or the loan, the Company will
obtain and furnish to the Authority the written Opinion of Counsel with respect
to such transaction and its effect on the tax exemption for the interest on the
Bonds.

      (o) Reasonable Expectations. To the best of the knowledge and belief of
the undersigned officer of the Authority, there are no facts, estimates or
circumstances other than those expressed herein that would adversely affect the
expectations expressed above and the Authority's expectations are reasonable.
The certifications set forth above are made for the purpose of establishing the
reasonable expectations of the Authority as to the amount and use of proceeds of
the Bonds and certain other amounts. They are intended and may be relied upon as
a certification described in Section 1.148-2(b) of the Treasury Regulations or
successor regulations and delivered as part of the record of proceedings in
connection with the issuance of the Bonds.

      Section 8.5. Universal Cap Limit on Allocation of Nonpurpose Investments.

      (a) General Rule. Nonpurpose Investments of Gross Proceeds are allocated
to the Bonds only to the extent that the Value of such investments does not
exceed the Universal Cap.

      (b) Exception. Nonpurpose Investments of Gross Proceeds in a Bona Fide
Debt Service Fund (e.g., the Debt Service Fund other than a carryover amount in
excess of one-twelfth of debt service on the Bonds for the preceding Bond Year
and any capitalized interest account) are allocated to the Bonds without regard
to the Universal Cap.

      (c) Dates of Application of Universal Cap. The Universal Cap is applied on
the second anniversary date of the Date of Issue and on of the first day of each
Bond Year thereafter.

      (d) Valuation of Nonpurpose Investments. On each date of application of
the Universal Cap, all Nonpurpose Investments shall be valued at their Value.

      (e) Allocation of Amounts Exceeding Universal Cap. If on a date of
application of the Universal Cap, Nonpurpose Investments have a Value in excess
of the Universal Cap, the Value of such investments equal to such excess shall
cease to be allocated to the Bonds in the following order: (i) Nonpurpose
Investments of


                                      -47-
<PAGE>

replacement proceeds, (ii) Nonpurpose Investments of "transferred proceeds" and
(iii) Nonpurpose Investments of Sale Proceeds and Investment Proceeds.
Nonpurpose Investments which cease to be allocated to the Bonds shall be deemed
sold at their Value for purpose of the Rebate Requirement and shall be no longer
subject to Yield restriction.

      (f) Failure to Apply Universal Cap. A failure to apply the Universal Cap
does not violate the Code or applicable Treasury Regulations, if, in the absence
of the failure, the Bonds would have satisfied the Universal Cap rule.

      Section 8.6. Yield Reduction Payments. Any amount paid to the United
States, including a rebate amount, shall be treated as a payment for the
investment that reduces the yield on the investment. Eligible investments
include:

      (a) Nonpurpose investments allocable to proceeds of an issue that
      qualified for a temporary period under Treasury Regulation Section
      1.148-2(e)(2), (3), (4) or (6);

      (b) Investments allocable to an issue in which at least 5% of the Value of
      the issue is composed of Variable Yield Bonds, unless the issue is a
      "hedge bond";

      (c) Nonpurpose Investments allocable to transferred proceeds of a current
      refunding issue or an advance refunding issue which cannot comply with
      Yield restriction by investing in zero yield obligations;

      (d) Replacement proceeds in a nonqualified reserve fund (due to exceeding
      the size limitation) and such amounts are either (i) not greater than 15%
      of the principal amount or the issue price if there is more than de
      minimis original issue discount or premium or (ii) such amounts are not
      expected to be used for debt service on the Bonds; and

      (e) Replacement proceeds of a refunded issue due to the Universal Cap
      rule.

      Yield Reduction Payments shall be made at the same time and in the same
manner as rebate payments or as the Commissioner of Internal Revenue prescribes
otherwise.

      Section 8.7. Non-Arbitrage Certifications of the Company. The Company has
read Section 8.5 of this Tax Regulatory Agreement. The Company acknowledges that
said section sets forth (i) the Authority's reasonable expectations as to the
amount, investment, expenditure and use of the proceeds of the Bonds, other
amounts held under the Indenture, and earnings derived from the investment of
the foregoing, all in respect of the Bonds,


                                      -48-
<PAGE>

(ii) amounts due to the Authority under the Loan Agreement and (iii) the facts,
estimates and circumstances existing on the date hereof which form the basis for
such expectations of the Authority. The Company recognizes that certain of the
facts, estimates and circumstances forming the basis of the Authority's
certifications are within the knowledge of the Company and that, as indicated in
Section 8.4(m), the Authority is relying on the Company as to the accuracy and
completeness of such matters. The Company hereby certifies that the statements
made in the paragraphs referenced in Section 8.4(m) as made in reliance on the
Company are accurate, complete and reasonable in all material respects and the
Company consents to the Authority's reliance on this certification for the
purpose of delivering its Non- Arbitrage Certifications. The Company certifies
that it is not aware of any facts or circumstances that would cause it to
question the accuracy or completeness of the matters recited in Section 8.4 of
this Tax Regulatory Agreement.

                                   ARTICLE IX

                     $40 MILLION LIMITATION ON PAB ACTIVITY

      Section 9.1. Current Test-Period Beneficiaries of the Bonds. The Company
represents that currently, the only Test- Period Beneficiaries of the Bonds are
the Company and any Related Person to the foregoing.

      Section 9.2. Current Compliance. The Company represents that as of this
date, except as set forth in Schedule G hereto, there are no outstanding
Tax-Exempt Private Activity Bonds that finance facilities which are or were used
by the Company and any Related Person or any Successor Person in a manner
causing any of them to be a Test-Period Beneficiary of such obligations.

      Section 9.3. Future Compliance. The Company covenants that before taking
any of the actions described in subsections (a),(b) or (c) below, it shall file
with the Authority a Certificate of Compliance with the $40 Million Tax-Exempt
Private Activity Bond Limit establishing that the portion of the original
principal amount of the Bonds allocable to a Test-Period Beneficiary plus the
amount of Tax-Exempt Private Activity Bonds which are allocable to such
Test-Period Beneficiary and which are outstanding on the Date of Issue of the
Bonds does not exceed $40 million.

      (a) Other Facilities. The action described in this paragraph is that the
Company or a Related Person or another Test-Period Beneficiary, if any, of the
Bonds, becomes an owner or user of a facility financed with Tax-Exempt Private
Activity Bonds outstanding on the Date of Issue of the Bonds.

      (b) Other Test-Period Beneficiaries. The actions described in this
paragraph are that the Company or any Related Person to the foregoing in cases
(i) and (iii) below, or another Test-Period Beneficiary, if any, of the Bonds
(including a Related Person thereto) in cases (i) - (iii) below: (i) leases or
sells more than 10% of the Project, measured by space, capacity or value to
another person; (ii) increases its percentage of ownership or use of the
Project; or (iii) otherwise takes any action causing any person not previously
treated as a Test-Period Beneficiary of the Bonds to become a Test-Period
Beneficiary of the Bonds.

      (c) Additional Related Persons. The actions described in this paragraph
are that the Company, or another Test-Period Beneficiary, if any, of the Bonds,
or a Related Person to any of the foregoing, (i) merges, consolidates with,
acquires more than a 50% interest in, or is acquired by another person or entity
or


                                      -50-
<PAGE>

(ii) transfers substantially all of its properties to any person or entity, who
is not, prior to such transfer, a Related Person, (iii) receives substantially
all of the assets of any person or entity, who is not, prior to such transfer, a
Related Person, or (iv) acquires or transfers assets to or from a corporation
(who is not, prior to such event, a Related Person) in a transaction described
in Code Section 381(a). Actions described in this paragraph also include a
Test-Period Beneficiary (including the Company) of the Bonds or a Related Person
to such Test Period Beneficiary taking action that results in another person or
entity becoming a Related Person to such Test-Period Beneficiary or Related
Person.

      Section 9.4. Allocation Rules.

      (a) General. The allocation of portions of issues of Bonds and Tax-Exempt
Private Activity Bonds and portions of facilities financed thereby to
Test-Period Beneficiaries shall be made in accordance with Code Section
144(a)(10)(C) and Proposed Treasury Regulation Section 1.103-10(i)(4) or any
successor regulation.

      (b) Maximum Allocation Rule. The portion of a bond issue allocable to a
Test-Period Beneficiary is the highest percent of the facility financed by the
issue that the beneficiary owned or used during the three-year period described
in the definition of Test-Period Beneficiary.

      (c) Amount of Issue Allocable to Related Person; No Double Counting. The
portion of a bond issue allocable to a Related Person of a Principal User of
facilities financed by the issue is the same portion allocable to such Principal
User. However, if both such persons use the same bond-financed facility, then
the portion of the bonds allocable to each such person shall be allocated only
once.

      (d) Certain Redeemed Bonds Not Counted. Tax-Exempt Private Activity Bonds
otherwise allocable to a Test-Period Beneficiary of the Bonds will not be so
allocated to the extent they are redeemed (other than from the proceeds of a
tax-exempt refunding issue) no later than 180 days after such beneficiary
becomes a Test-Period Beneficiary of the bonds to be redeemed.

                            COVENANTS AND AMENDMENTS

      Section 10.1. Compliance with Code.

      (a) The Company agrees and covenants that it shall at all times do and
perform all acts and things necessary or desirable and within their reasonable
control in order to ensure that interest paid on the Bonds shall, for the
purpose of Federal income taxation, be excludable from the gross income of the
recipients thereof, except in the event that such recipient is a Substantial

                            PUBLIC HEARING PROCEDURES
                       FOR FEDERAL TAX COMPLIANCE PURPOSES

      The Authority is required by current federal tax law to conduct a public
hearing regarding issues of industrial development bonds. Reasonable public
notice must be given in advance of the hearing. These procedures are adopted by
the Authority to guide the conduct of the federally required hearings.

      Reference. These procedures may be referred to by the Authority in its
certifications regarding industrial development bonds as "Public Hearing
Procedures for Federal Tax Compliance Purposes."

      Purpose. The purpose of these procedures is to provide general guidance
for the conduct of the public notice and public hearing requirements of Section
147(f) of the Internal Revenue Code of 1986, as amended (the "Code"), relating
to the issuance of certain tax-exempt industrial development bonds.

      Scope. Hearings concerning Self-Sustaining Program and Umbrella Program
notes and bonds shall be conducted substantially in accordance with these
guidelines, except to the extent alternative procedures may be approved by Bond
Counsel or by an Authorized Representative of the Authority as sufficient to
achieve the purpose of the hearings. No hearing need be conducted for issues or
portions of issues exempted from the hearing requirement by the Code.

      Authorization. The adoption of these procedures is authorized by the State
Commerce Act. Nothing contained therein, however, shall be construed to imply
that a public hearing regarding industrial development bonds is or shall be
required for the purposes of State law or that hearings conducted under these
procedures must be conducted under the Uniform Administrative Procedure Act.

      Timing. The public hearing for any industrial development bond issue may
be conducted at any time prior to the approval of the bonds by an appropriate
elected official of the State and authorization of the issuance of the bonds by
the Authority.

      Notice. Notice of the hearing scheduled for any proposed bond issue shall
be published, substantially in the form attached hereto as Appendix A, at least
14 calendar days in advance of the scheduled public hearing date.


                                      -54-
<PAGE>

      Newspaper. Notice shall be published in the newspaper for the city or town
in which the proposed project is to be located. The Authority, based on
reasonable inquiry and investigation, hereby determines that the publication of
notice in the manner provided herein is reasonably designed to apprise residents
of the affected city or town of the proposed issuance of the bonds.

      Location. The hearing shall be conducted at the offices of the Authority
in Rocky Hill, Connecticut. The Authority, based on reasonable inquiry and
investigation, hereby further determines that locating the hearing at such
offices would be convenient for persons affected by the facilities financed by
the bonds.

      Hearing Officer. Any Authorized Representative of the Authority may
conduct the public hearing. For this purpose, Authorized Representatives include
any member or duly designated alternate member of the Authority, the Executive
Director, the Deputy Director, any Program Manager and any Loan Officer.

      Subject. The public hearing shall address the subject of the nature and
location of the proposed project and the issuance of bonds to finance the
project.

      Conduct. The hearing shall be conducted at a time and in a manner that
provides reasonable opportunity for persons with differing views on the subject
of the hearing to be heard. The hearing officer shall present a short statement
regarding the subject of the hearing, including the identity of the
participants, the nature and location of the proposed project, the nature of the
bond issue, and the public purpose of the transaction. Reasonable questions and
verbal comment shall be entertained.

      In the discretion of the hearing officer, the time for verbal expression
may be limited or written statements accepted if appropriate in the
circumstances of the hearing. Priority of appearance and all other matters
necessary to assure the expeditious and orderly conduct of the hearing in the
interests of its purpose shall be determinatively established by the hearing
officer present. Hearings may be conducted in conjunction with or apart from
board meetings.

      For the convenience of the Authority or any other cause, hearings once
scheduled may be postponed, canceled, rescheduled, discontinued or recontinued
without restriction, except that notice shall be again published regarding any
rescheduled hearing to the extent it is required by the Code.

      In the event that for any proposed issue no persons appear to address the
hearing within one-half hour of the time scheduled


                                      -55-
<PAGE>

for its commencement, the hearing officer may declare the hearing to have been
held unattended and to be concluded.

      Plan of Financing. The public hearing also may address subsequent issues
of obligations to occur within three years of the initial issue providing
financing for a proposed project. The subsequent obligations may be issued for
refunding purposes or to provide financing for further phases of construction or
acquisition initially approved.

      of the Net Proceeds of the Bonds (excluding any investment earnings) as
      shown in Item 4 ($3,810,000) and therefore is less than the 25% limitation
      established by the Code.

                Industrial Development Revenue Bonds (Sonics &
                Materials, Inc. Project) Series 1997 (the "Bonds")

Gentlemen:

            This letter is furnished by Brown Brothers Harriman & Co., as the
purchaser of the Bonds, to provide the Connecticut Development Authority (the
"Authority") and Whitman Breed Abbott & Morgan LLP, as bond counsel in respect
of the Bonds, with certain information in connection with the issuance of the
Bonds. Unless otherwise defined, the capitalized terms used herein shall have
the same meaning as defined in the Tax Regulatory Agreement to which this letter
is attached.

            We hereby certify that we have purchased the Bonds as an investment
for its own account, without a present intent to reoffer the Bonds (as
participations in the Bonds) to others.

            No representation is made as to the legal sufficiency of this
certificate for any purpose. We assume no obligation to advise you of any
changes that come to our attention subsequent to the date hereof and that would
have caused us to alter in any respect the information set forth herein. We
understand that the foregoing information will be relied upon by the Authority
for the purposes of making certain of the representations contained in the Tax
Regulatory Agreement, and will be relied upon by counsel, Whitman Breed Abbott &
Morgan LLP, in rendering its opinion that interest on the Bonds is excludable
from gross income of the owners thereof for federal income tax purposes.
