                                  THE COMPANY

         The following summary is qualified in its entirety by reference to the
more detailed information and the financial statements and the related notes
appearing elsewhere in the Prospectus or incorporated herein by reference. Each
prospective investor is urged to read this Prospectus in its entirety.
Investment in the securities offered hereby involves certain risks. See "Risk
Factors."

         American Technical Ceramics Corp. (the "Company") designs, develops,
manufactures and markets RF/Microwave/Millimeter-Wave ceramic and porcelain
capacitors and thin film products. The Registrant believes that it is a leading
manufacturer of multilayer capacitors ("MLCs") for ultra-high frequency ("UHF")
and microwave applications.

         The Company's MLCs are generally designed for critical performance
applications, and are characterized by a high degree of reliability, low power
dissipation and ruggedness. The Company's products are used in commercial and
military applications, including satellite communications, Personal
Communications Systems (PCS) and other wireless communications systems, medical
imaging (i.e., magnetic resonance imaging), radio frequency power sources for
semiconductor manufacturing, numerous aerospace systems, including radar and
electronic warfare, and certain high-speed digital processing equipment.

         The Company has historically pursued the high-performance MLC market
which has commanded high unit selling prices. The MLCs required for these
applications constitute a small part of the circuit cost and, because
performance requirements are stringent and the cost of component failure high,
customers have been willing to pay the higher prices associated with higher
performance products. In recent years, the Company has accelerated the
mechanization of its manufacturing processes to produce certain of its existing
MLCs at lower cost for the medium-priced communications market to supplement
the range of applications met by its product offerings.

         The Company has diversified its product line in recent years through
the development of product based on thin film technologies. These additional
products enable the Company to offer custom metalization and patterned
substrates for a broad range of hybrid circuit requirements. Typical
applications include, among others, microwave attenuators, filters, resistors,
amplifiers and capacitors.

                                  RISK FACTORS

         In evaluating an investment in the Common Stock being offered hereby,
investors should consider carefully, among other things, the following risk
factors, as well as the other information contained in this Prospectus.

Sales to OEMs and the U.S. Military

         The Company's products are used in the production of a variety of
highly complex electronic products manufactured by original equipment
manufacturers ("OEMs") for the military and for commercial use. Accordingly,
demand for the Company's products is highly dependent upon demand for the
products in which they are used. A reduction in demand for the electronic
products in which the Company's products are used could have a material adverse
effect on the Company's business.

         In addition, the Company sells a significant amount of hi-rel products
for end use by the U.S. military. Such sales require the Company to be
qualified with the Defense Logistics Agency of the U.S. Department of Defense.
There can be no assurance that the Company will be able to maintain such
qualification and failure to do so would have a material adverse effect on the
Company's sales to the U.S. military. Sales to the U.S. military are also
subject to various risks, including, without limitation, unpredictable
reductions in the funds available to purchase products and contract termination
for the convenience of the government.

Absence of Long-Term Contracts with Customers

         The Company generally does not have long-term or exclusive contracts
with its customers or suppliers. Sales to customers are generally made pursuant
to purchase orders. While the Company is not materially dependent upon sales to
any single customer, the loss of, or a significant change in, the relationship
between the Company and its key customers could have a material adverse effect
on the Company's business.

                                     - 3 -

<PAGE>

Risks Associated with Technological Change

         The technology upon which the Company's products are based is subject
to continuous development of materials and processes. The Company's business is
in large part contingent upon the continuous refinement of its technological
and engineering expertise and the development of new or enhanced products and
technologies to meet the rapidly developing demands of new applications and
increased competition. There can be no assurance that the Company will continue
to be successful in its efforts to develop new or refine existing products or
that it will otherwise be able to timely identify and respond to technological
improvements made by its competitors. Significant technological breakthroughs
by others could have a material adverse effect on the Company's business.

Availability of Certain Raw Materials

         Although the Company generally uses readily obtainable raw materials
and supplies in the manufacture of its products, palladium, a precious metal
used in the production of the Company's capacitors, is currently available from
a limited number of metal dealers who obtain palladium from Russia or the
Republic of South Africa. The availability and cost of palladium has
historically been, and may continue to be, subject to changes in government
policies, tariffs, import restrictions and other factor's beyond the Company's
control. An interruption or reduction of exports of palladium by Russia or the
Republic of South Africa could have a material adverse effect on the Company's
business.

Risks Associated with International Sales

         Sales to customers located outside of the United States constituted
32%, 33% and 36% of the Company's net sales during the fiscal years ended June
30, 1997, 1996 and 1995, respectively. The Company anticipates that
international sales will continue to constitute a substantial portion of is
total sales. These sales expose the Company to certain risks, including,
without limitation, barriers to trade, fluctuations in foreign currency
exchange rates (which may make the Company's products less price competitive),
political and economic instability, changes in monetary policy, tariff
regulations and other U.S. and foreign laws and regulations that may apply to
the export of the Company's products, as well as the generally greater
difficulties of doing business abroad.

Fluctuations in Quarterly Results

         The Company offers a broad array of products to its customers. Gross
margins can vary significantly from product to product and across product
lines. Accordingly, a change in the mix of products sold by the Company during
a particular period could lead to distinctly different financial results for
that period as compared to other periods. In addition, certain raw materials
used by the Company may fluctuate in price, and to the extent that the Company
is unable to pass on increases in the costs of such materials to its customers,
such increases could have a material adverse effect on the gross profit margins
on products incorporating such raw materials. The Company's revenues and gross
margins may also vary from quarter to quarter as a result of a variety of
factors, including, without limitation, the timing of customer orders and
competitive pricing pressures.

Changes in Processes and Production Capacities

         The Company from time to time makes modifications to its manufacturing
processes as a result of technological improvements it has developed or the
requirements of new products or refinements to existing products. The Company
may also increase its production capacity from time to time in order to meet
actual or projected increases in demand for its products. These changes and
increases may result in lower production yields while the modified or new
production lines are adjusted for optimum efficiency. These circumstances could
lead to further fluctuations in quarterly results.

Competition

         Competition in the MLC industry is intense and, in general, is based
primarily on price. In the hi-rel and UHF/Microwave market segments, where
price has historically been less important, competition has been based
primarily on high performance product specifications, achieving consistent
product reliability, fast deliveries and high levels of customer service. The
Company competes with a number of larger MLC manufacturers who have broader
product lines and greater financial, marketing and technical resources than the
Company. Potential growth of some commercial market applications may in the
future increase the competitive importance of price. There can be no assurance
that the Company will be able to improve the productivity and efficiency of its
manufacturing processes in order to respond to pricing pressures and the
failure to do so could have a material adverse effect on the Company's
business.

                                     - 4 -
<PAGE>

Uncertainties Regarding Intellectual Property

         Although the Company has manufacturing and design patents and pending
patent applications, and although the Company will continue to seek the
supplemental protection afforded by patents, the Company generally considers
protection of its products, processes and materials to be more dependent upon
proprietary knowledge and on rapid assimilation of innovations than on patent
protection. The Company's porcelain and ceramic formulations are considered
trade secrets which are protected by internal non-disclosure safeguards and
employee confidentiality agreements. There can be no assurance that the steps
taken by the Company to protect its proprietary rights will be adequate to
deter misappropriation, or that an independent third party will not develop
functionally equivalent technology.

         While the Company believes its present products and technology do not
infringe the patents or intellectual property rights of others and is not aware
of any threatened patent or intellectual property infringement claims against
it, there can be no assurance that such claims will not be asserted against the
Company in the future. Any such claims in the future could result in the
Company being required to enter into royalty arrangements, cease manufacturing
the infringing products or utilizing infringing technologies, pay damages or
defend litigation, any of which could have a material adverse effect on the
Company's business.

Impact of Environmental Regulation

         The Company is subject to the requirements of federal, state and local
environmental and occupational health and safety laws and regulations. The
Company has made and will continue to make capital and other expenditures to
comply with environmental requirements. There can be no assurance that the
Company will always be in complete compliance with all such requirements.

         The Company does produce limited quantities of hazardous wastes in the
production of its capacitors. Accordingly, if a release of hazardous substances
occurs on or from the Company's properties or from any of its disposal
locations, or if contamination is discovered at any of the Company's
properties, the Company may be held liable, and the amount of such liability
and remediation costs could have a material adverse effect on the Company's
business.

Dependence on Key Personnel

         The success of the Company is largely dependent on the continued
efforts and abilities of Victor Insetta, the Company's President and Chief
Executive Officer. The Company has an employment agreement with Mr. Insetta and
maintains key-person life insurance in the amount of $4,000,000. The loss of
the services of Mr. Insetta could have a material adverse effect on the
Company.

Control by Principal Stockholder

         As of the date hereof, Victor Insetta, the Company's President and
Chief Executive Officer, owns 2,300,061 shares of Common Stock which represents
approximately 58.9% of the Company's outstanding Common Stock. As a result of
such ownership and control, Mr. Insetta has the ability to control the election
of directors of the Company and the outcome of all issues submitted to a vote
of the stockholders of the Company.

Lack of Dividends

         The Company has not paid any dividends on the Common Stock and does
not intend to pay any dividends to its stockholders in the foreseeable future.
The Company currently intends to reinvest earnings in the development and
expansion of its business.

                                USE OF PROCEEDS

         The Company is unable to predict the time, if ever, when the Options
will be granted and exercised and, therefore, is unable to estimate the net
proceeds from the exercise of the Options. Moreover, the Plan permits certain
methods of exercising Options which would not result in the Company receiving
any cash proceeds. It is expected that the net proceeds from the sale of the
Shares to the Selling Security Holders upon exercise of the Options, if any,
will be used by the Company for general corporate purposes. The Company will
not receive any proceeds from the subsequent sale of the Shares by the Selling
Security Holders.

                            SELLING SECURITY HOLDERS

         As the names and amounts of securities to be sold by Selling Security
Holders become known, the following information will be included in a
prospectus supplement: the name and position(s) over the last three years with
the Company of each Selling Security Holder; the number of shares of Common
Stock owned by each Selling Security Holder; the number of shares of Common
Stock available to be acquired by each Selling Security Holder pursuant to the
Plan and being registered for resale by the Selling Security Holders; and the
number of shares of Common Stock and the percentage, if 1% or more, of the
total number of shares of Common Stock outstanding to be beneficially owned by
each Selling Security Holder following this offering.

                          DESCRIPTION OF CAPITAL STOCK

         The following summary description of the Company's capital stock is
qualified in its entirety by reference to the Company's Certificate of
Incorporation, as amended.

         The Company is authorized to issue 20,000,000 shares of Common Stock,
par value $.01 per share. At April 20, 1998, there were 3,900,410 shares of
Common Stock outstanding held by approximately 356 stockholders of record.

         The holders of Common Stock are entitled to one vote per share on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Holders of Common Stock are entitled to receive ratably such dividends,
if any, as may be declared by the Board of Directors out of funds legally
available therefor. In the event of liquidation, dissolution or winding up of
the Company, holders of Common Stock are entitled to share ratably in all
assets remaining after payment of liabilities. Holders of Common Stock have no
preemptive, subscription, redemption or conversion rights. All the outstanding
shares of Common Stock are, and the Common Stock to be issued in this offering
will be, validly issued, fully paid and nonassessable.

Delaware Law and Certain Charter and By-Law Provisions

         The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. Section 203 prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless (i) before such
person became an interested stockholder, the board of directors of the
corporation approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (ii) upon
consummation of the transaction that resulted in the interested stockholder's
becoming an interested stockholder, the interested stockholder owned at least
85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding stock held by directors who are also officers
of the corporation and by employee stock plans that do not provide employees
with the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer); or (iii) following the
transaction in which such person becomes an interested stockholder, the
business consummation is approved by the board of directors of the corporation
and authorized at a meeting of stockholders by the affirmative vote of the
holders of 66 2/3% of the outstanding voting stock of the corporation not owned
by the interested stockholder. A "business combination" includes mergers, asset
sales and other transactions resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within three
years did own, 15% or more of the corporation's voting stock.

         The Company's Certificate of Incorporation contains certain provisions
permitted under the General Corporation Law of Delaware relating to the
liability of directors. The provisions eliminate a director's liability for
monetary damages for a breach of fiduciary duty, except in certain
circumstances involving wrongful acts, such as the breach of a director's duty
of loyalty or acts or omissions which involve intentional misconduct or a
knowing violation of law. Further, the Company's Certificate of Incorporation
contains provisions to indemnify the Company's directors and officers to the
fullest extent permitted by the General Corporation Law of Delaware. The
Company believes that these provisions will assist the Company in attracting
and retaining qualified individuals to serve as directors.

                                 TRANSFER AGENT

         The Company has appointed American Stock Transfer Co., New York, New
York as transfer agent for the Common Stock.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Delaware General Corporation Law, Section 102(b)(7) enables a
corporation in its original certificate of incorporation or an amendment
thereto validly approved by stockholders to eliminate or limit personal
liability of members of its Board of Directors for violations of a director's
fiduciary duty of care , subject to certain exceptions. The Company's
Certificate of Incorporation includes the following language:

         "No director shall be personally liable to the Corporation or any
stockholder for monetary damages for breach of fiduciary duty as a director,
except for any matter in respect to which such director shall be liable under
Section 174 of Title 8 of the Delaware Code or any amendment thereto or
successor provision thereto or shall be liable by reason that, in addition to
any and all other requirements for such liability, he (i) shall have breached
his duty of loyalty to the Corporation or its stockholders, (ii) shall have
acted, or failed to act, in a manner that is not in good faith, (iii) shall
have acted, or failed to act, in a manner involving intentional misconduct or
a knowing violation of law or (iv) shall have derived an improper personal
benefit."

         Delaware General Corporation Law, Section 145, permits a corporation
organized under Delaware law to indemnify directors and officers with respect
to any matter in which the director or officer acted in good faith and in a
manner he reasonably believed to be not opposed to the best interests of the
Company, and, with respect to any criminal action, had reasonable cause to
believe his conduct was lawful. The By-Laws of the Company include the
following provision:

         "Every person (and the heirs, executors and administrators of such
person) who is or was a director, officer, employee or agent of the Corporation
or of any other company, including another corporation, partnership, joint
venture, trust or other enterprise in which such person serves or served as
such at the request of the Corporation, shall be indemnified by the Corporation
against all judgments, payments in settlement (whether or not approved by
court), fines, penalties and other reasonable costs and expenses (including
fees and disbursements of counsel) imposed upon or incurred by such person in
connection with or resulting from any action, suit, proceeding, investigation
or claim, civil, criminal, administrative, legislative or other (including any
criminal action, suit or proceeding in which such person enters a plea of
guilty or nolo contendere or its equivalent), or any appeal relating thereto,
which is brought or threatened either by or in the right of the Corporation or
such other person, governmental authority or instrumentality (herein called a
"third-party action") and in which such person is made a party or is otherwise
involved by reason of his being or having been such director, officer, employee
or agent or by reason of any action or omission, or alleged action or omission,
by such person in his capacity as such director, officer, employee

                                     II-1

<PAGE>

or agent if either (a) such person is wholly successful, on the merits or
otherwise, in defending such derivative or third-party action or (b) in the
judgment of a court of competent jurisdiction or, in the absence of such
determination, in the judgment of a majority of a quorum of the Board of
Directors of the Corporation (which quorum shall not include any director who
is a party to or is otherwise involved in such action) or, in their absence of
such a disinterested quorum, in the opinion of independent legal counsel (i) in
the case of a derivative action, such person acted without negligence or
misconduct in the performance of his duty to the Corporation or such other
company or (ii) in the case of a third-party action, such person acted in good
faith in what he reasonably believed to be the best interests of the
Corporation or such other company and, in addition, in any criminal action, had
no reasonable cause to believe that his action was unlawful, provided that, in
the case of a derivative action, such indemnification shall not be made in
respect of any payment to the Corporation or such other company or any
stockholder thereof in satisfaction of judgment or in settlement unless either
(x) a court of competent jurisdiction has approved such settlement, if any, and
the reimbursement of such payment or (y) if the court in which such action has
been instituted lacks jurisdiction to grant such approval or such action is
settled before the institution of judicial proceedings, in the opinion of
independent legal counsel the applicable standard of conduct specified
hereinbefore has been met, such action was without substantial merit, such
settlement was in the best interests of the Corporation or such other company
and the reimbursement of such payment is permissible under applicable law. In
case such person is successful, on the merits or otherwise, in defending part
of such action or, in the judgment of such a court or such quorum of the Board
of Directors or in the opinion of such counsel, has met the applicable standard
of conduct specified in the preceding sentence with respect to part of such
action, he shall be indemnified by the Corporation against judgments,
settlements, payments, fines, penalties and other costs and expenses
attributable to such part of such action."

ITEM 9.  UNDERTAKINGS

    (a) The undersigned registrant hereby undertakes:

    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

         (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act;

         (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in the
    Registration Statement;

                                      II-2

<PAGE>

         (iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or any
    material change to such information in the Registration Statement;

    provided, however, that paragraphs (a)(l)(i) and (a)(l)(ii) do not apply
    if the information required to be included in a post-effective amendment
    by those paragraphs is contained in periodic reports filed by the
    registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
    that are incorporated by reference in the Registration Statement;

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

    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.

    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15 (d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be
a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

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

THE COMPANY

         The following summary is qualified in its entirety by reference to the
more detailed information and the financial statements and the related notes
appearing elsewhere in the Prospectus or incorporated herein by reference. Each
prospective investor is urged to read this Prospectus in its entirety.
Investment in the securities offered hereby involves certain risks. See "Risk
Factors."

         American Technical Ceramics Corp. (the "Company") designs, develops,
manufactures and markets RF/Microwave/Millimeter-Wave ceramic and porcelain
capacitors and thin film products. The Registrant believes that it is a leading
manufacturer of multilayer capacitors ("MLCs") for ultra-high frequency ("UHF")
and microwave applications.

         The Company's MLCs are generally designed for critical performance
applications, and are characterized by a high degree of reliability, low power
dissipation and ruggedness. The Company's products are used in commercial and
military applications, including satellite communications, Personal
Communications Systems (PCS) and other wireless communications systems, medical
imaging (i.e., magnetic resonance imaging), radio frequency power sources for
semiconductor manufacturing, numerous aerospace systems, including radar and
electronic warfare, and certain high-speed digital processing equipment.

         The Company has historically pursued the high-performance MLC market
which has commanded high unit selling prices. The MLCs required for these
applications constitute a small part of the circuit cost and, because
performance requirements are stringent and the cost of component failure high,
customers have been willing to pay the higher prices associated with higher
performance products. In recent years, the Company has accelerated the
mechanization of its manufacturing processes to produce certain of its existing
MLCs at lower cost for the medium-priced communications market to supplement
the range of applications met by its product offerings.

         The Company has diversified its product line in recent years through
the development of product based on thin film technologies. These additional
products enable the Company to offer custom metalization and patterned
substrates for a broad range of hybrid circuit requirements. Typical
applications include, among others, microwave attenuators, filters, resistors,
amplifiers and capacitors.

                                  RISK FACTORS

         In evaluating an investment in the Common Stock being offered hereby,
investors should consider carefully, among other things, the following risk
factors, as well as the other information contained in this Prospectus.

Sales to OEMs and the U.S. Military

         The Company's products are used in the production of a variety of
highly complex electronic products manufactured by original equipment
manufacturers ("OEMs") for the military and for commercial use. Accordingly,
demand for the Company's products is highly dependent upon demand for the
products in which they are used. A reduction in demand for the electronic
products in which the Company's products are used could have a material adverse
effect on the Company's business.

         In addition, the Company sells a significant amount of hi-rel products
for end use by the U.S. military. Such sales require the Company to be
qualified with the Defense Logistics Agency of the U.S. Department of Defense.
There can be no assurance that the Company will be able to maintain such
qualification and failure to do so would have a material adverse effect on the
Company's sales to the U.S. military. Sales to the U.S. military are also
subject to various risks, including, without limitation, unpredictable
reductions in the funds available to purchase products and contract termination
for the convenience of the government.

Absence of Long-Term Contracts with Customers

         The Company generally does not have long-term or exclusive contracts
with its customers or suppliers. Sales to customers are generally made pursuant
to purchase orders. While the Company is not materially dependent upon sales to
any single customer, the loss of, or a significant change in, the relationship
between the Company and its key customers could have a material adverse effect
on the Company's business.

                                     - 3 -
Risks Associated with Technological Change

         The technology upon which the Company's products are based is subject
to continuous development of materials and processes. The Company's business is
in large part contingent upon the continuous refinement of its technological
and engineering expertise and the development of new or enhanced products and
technologies to meet the rapidly developing demands of new applications and
increased competition. There can be no assurance that the Company will continue
to be successful in its efforts to develop new or refine existing products or
that it will otherwise be able to timely identify and respond to technological
improvements made by its competitors. Significant technological breakthroughs
by others could have a material adverse effect on the Company's business.

Availability of Certain Raw Materials

         Although the Company generally uses readily obtainable raw materials
and supplies in the manufacture of its products, palladium, a precious metal
used in the production of the Company's capacitors, is currently available from
a limited number of metal dealers who obtain palladium from Russia or the
Republic of South Africa. The availability and cost of palladium has
historically been, and may continue to be, subject to changes in government
policies, tariffs, import restrictions and other factor's beyond the Company's
control. An interruption or reduction of exports of palladium by Russia or the
Republic of South Africa could have a material adverse effect on the Company's
business.

Risks Associated with International Sales

         Sales to customers located outside of the United States constituted
32%, 33% and 36% of the Company's net sales during the fiscal years ended June
30, 1997, 1996 and 1995, respectively. The Company anticipates that
international sales will continue to constitute a substantial portion of is
total sales. These sales expose the Company to certain risks, including,
without limitation, barriers to trade, fluctuations in foreign currency
exchange rates (which may make the Company's products less price competitive),
political and economic instability, changes in monetary policy, tariff
regulations and other U.S. and foreign laws and regulations that may apply to
the export of the Company's products, as well as the generally greater
difficulties of doing business abroad.

Fluctuations in Quarterly Results

         The Company offers a broad array of products to its customers. Gross
margins can vary significantly from product to product and across product
lines. Accordingly, a change in the mix of products sold by the Company during
a particular period could lead to distinctly different financial results for
that period as compared to other periods. In addition, certain raw materials
used by the Company may fluctuate in price, and to the extent that the Company
is unable to pass on increases in the costs of such materials to its customers,
such increases could have a material adverse effect on the gross profit margins
on products incorporating such raw materials. The Company's revenues and gross
margins may also vary from quarter to quarter as a result of a variety of
factors, including, without limitation, the timing of customer orders and
competitive pricing pressures.

Changes in Processes and Production Capacities

         The Company from time to time makes modifications to its manufacturing
processes as a result of technological improvements it has developed or the
requirements of new products or refinements to existing products. The Company
may also increase its production capacity from time to time in order to meet
actual or projected increases in demand for its products. These changes and
increases may result in lower production yields while the modified or new
production lines are adjusted for optimum efficiency. These circumstances could
lead to further fluctuations in quarterly results.

Competition

         Competition in the MLC industry is intense and, in general, is based
primarily on price. In the hi-rel and UHF/Microwave market segments, where
price has historically been less important, competition has been based
primarily on high performance product specifications, achieving consistent
product reliability, fast deliveries and high levels of customer service. The
Company competes with a number of larger MLC manufacturers who have broader
product lines and greater financial, marketing and technical resources than the
Company. Potential growth of some commercial market applications may in the
future increase the competitive importance of price. There can be no assurance
that the Company will be able to improve the productivity and efficiency of its
manufacturing processes in order to respond to pricing pressures and the
failure to do so could have a material adverse effect on the Company's
business.

                                     - 4 -
Uncertainties Regarding Intellectual Property

         Although the Company has manufacturing and design patents and pending
patent applications, and although the Company will continue to seek the
supplemental protection afforded by patents, the Company generally considers
protection of its products, processes and materials to be more dependent upon
proprietary knowledge and on rapid assimilation of innovations than on patent
protection. The Company's porcelain and ceramic formulations are considered
trade secrets which are protected by internal non-disclosure safeguards and
employee confidentiality agreements. There can be no assurance that the steps
taken by the Company to protect its proprietary rights will be adequate to
deter misappropriation, or that an independent third party will not develop
functionally equivalent technology.

         While the Company believes its present products and technology do not
infringe the patents or intellectual property rights of others and is not aware
of any threatened patent or intellectual property infringement claims against
it, there can be no assurance that such claims will not be asserted against the
Company in the future. Any such claims in the future could result in the
Company being required to enter into royalty arrangements, cease manufacturing
the infringing products or utilizing infringing technologies, pay damages or
defend litigation, any of which could have a material adverse effect on the
Company's business.

Impact of Environmental Regulation

         The Company is subject to the requirements of federal, state and local
environmental and occupational health and safety laws and regulations. The
Company has made and will continue to make capital and other expenditures to
comply with environmental requirements. There can be no assurance that the
Company will always be in complete compliance with all such requirements.

         The Company does produce limited quantities of hazardous wastes in the
production of its capacitors. Accordingly, if a release of hazardous substances
occurs on or from the Company's properties or from any of its disposal
locations, or if contamination is discovered at any of the Company's
properties, the Company may be held liable, and the amount of such liability
and remediation costs could have a material adverse effect on the Company's
business.

Dependence on Key Personnel

         The success of the Company is largely dependent on the continued
efforts and abilities of Victor Insetta, the Company's President and Chief
Executive Officer. The Company has an employment agreement with Mr. Insetta and
maintains key-person life insurance in the amount of $4,000,000. The loss of
the services of Mr. Insetta could have a material adverse effect on the
Company.

Control by Principal Stockholder

         As of the date hereof, Victor Insetta, the Company's President and
Chief Executive Officer, owns 2,300,061 shares of Common Stock which represents
approximately 58.9% of the Company's outstanding Common Stock. As a result of
such ownership and control, Mr. Insetta has the ability to control the election
of directors of the Company and the outcome of all issues submitted to a vote
of the stockholders of the Company.

Lack of Dividends

         The Company has not paid any dividends on the Common Stock and does
not intend to pay any dividends to its stockholders in the foreseeable future.
The Company currently intends to reinvest earnings in the development and
expansion of its business.

                                USE OF PROCEEDS

         The Company is unable to predict the time, if ever, when the Options
will be granted and exercised and, therefore, is unable to estimate the net
proceeds from the exercise of the Options. Moreover, the Plan permits certain
methods of exercising Options which would not result in the Company receiving
any cash proceeds. It is expected that the net proceeds from the sale of the
Shares to the Selling Security Holders upon exercise of the Options, if any,
will be used by the Company for general corporate purposes. The Company will
not receive any proceeds from the subsequent sale of the Shares by the Selling
Security Holders.

                                     - 5 -
SELLING SECURITY HOLDERS

         As the names and amounts of securities to be sold by Selling Security
Holders become known, the following information will be included in a
prospectus supplement: the name and position(s) over the last three years with
the Company of each Selling Security Holder; the number of shares of Common
Stock owned by each Selling Security Holder; the number of shares of Common
Stock available to be acquired by each Selling Security Holder pursuant to the
Plan and being registered for resale by the Selling Security Holders; and the
number of shares of Common Stock and the percentage, if 1% or more, of the
total number of shares of Common Stock outstanding to be beneficially owned by
each Selling Security Holder following this offering.

                          DESCRIPTION OF CAPITAL STOCK

         The following summary description of the Company's capital stock is
qualified in its entirety by reference to the Company's Certificate of
Incorporation, as amended.

         The Company is authorized to issue 20,000,000 shares of Common Stock,
par value $.01 per share. At April 20, 1998, there were 3,900,410 shares of
Common Stock outstanding held by approximately 356 stockholders of record.

         The holders of Common Stock are entitled to one vote per share on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Holders of Common Stock are entitled to receive ratably such dividends,
if any, as may be declared by the Board of Directors out of funds legally
available therefor. In the event of liquidation, dissolution or winding up of
the Company, holders of Common Stock are entitled to share ratably in all
assets remaining after payment of liabilities. Holders of Common Stock have no
preemptive, subscription, redemption or conversion rights. All the outstanding
shares of Common Stock are, and the Common Stock to be issued in this offering
will be, validly issued, fully paid and nonassessable.

Delaware Law and Certain Charter and By-Law Provisions

         The Company is subject to the provisions of Section 203 of the General
Corporation Law of Delaware. Section 203 prohibits a publicly-held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless (i) before such
person became an interested stockholder, the board of directors of the
corporation approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (ii) upon
consummation of the transaction that resulted in the interested stockholder's
becoming an interested stockholder, the interested stockholder owned at least
85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding stock held by directors who are also officers
of the corporation and by employee stock plans that do not provide employees
with the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer); or (iii) following the
transaction in which such person becomes an interested stockholder, the
business consummation is approved by the board of directors of the corporation
and authorized at a meeting of stockholders by the affirmative vote of the
holders of 66 2/3% of the outstanding voting stock of the corporation not owned
by the interested stockholder. A "business combination" includes mergers, asset
sales and other transactions resulting in a financial benefit to the interested
stockholder. Subject to certain exceptions, an "interested stockholder" is a
person who, together with affiliates and associates, owns, or within three
years did own, 15% or more of the corporation's voting stock.

         The Company's Certificate of Incorporation contains certain provisions
permitted under the General Corporation Law of Delaware relating to the
liability of directors. The provisions eliminate a director's liability for
monetary damages for a breach of fiduciary duty, except in certain
circumstances involving wrongful acts, such as the breach of a director's duty
of loyalty or acts or omissions which involve intentional misconduct or a
knowing violation of law. Further, the Company's Certificate of Incorporation
contains provisions to indemnify the Company's directors and officers to the
fullest extent permitted by the General Corporation Law of Delaware. The
Company believes that these provisions will assist the Company in attracting
and retaining qualified individuals to serve as directors.

                                 TRANSFER AGENT

         The Company has appointed American Stock Transfer Co., New York, New
York as transfer agent for the Common Stock.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Delaware General Corporation Law, Section 102(b)(7) enables a
corporation in its original certificate of incorporation or an amendment
thereto validly approved by stockholders to eliminate or limit personal
liability of members of its Board of Directors for violations of a director's
fiduciary duty of care , subject to certain exceptions. The Company's
Certificate of Incorporation includes the following language:

         "No director shall be personally liable to the Corporation or any
stockholder for monetary damages for breach of fiduciary duty as a director,
except for any matter in respect to which such director shall be liable under
Section 174 of Title 8 of the Delaware Code or any amendment thereto or
successor provision thereto or shall be liable by reason that, in addition to
any and all other requirements for such liability, he (i) shall have breached
his duty of loyalty to the Corporation or its stockholders, (ii) shall have
acted, or failed to act, in a manner that is not in good faith, (iii) shall
have acted, or failed to act, in a manner involving intentional misconduct or
a knowing violation of law or (iv) shall have derived an improper personal
benefit."

         Delaware General Corporation Law, Section 145, permits a corporation
organized under Delaware law to indemnify directors and officers with respect
to any matter in which the director or officer acted in good faith and in a
manner he reasonably believed to be not opposed to the best interests of the
Company, and, with respect to any criminal action, had reasonable cause to
believe his conduct was lawful. The By-Laws of the Company include the
following provision:

         "Every person (and the heirs, executors and administrators of such
person) who is or was a director, officer, employee or agent of the Corporation
or of any other company, including another corporation, partnership, joint
venture, trust or other enterprise in which such person serves or served as
such at the request of the Corporation, shall be indemnified by the Corporation
against all judgments, payments in settlement (whether or not approved by
court), fines, penalties and other reasonable costs and expenses (including
fees and disbursements of counsel) imposed upon or incurred by such person in
connection with or resulting from any action, suit, proceeding, investigation
or claim, civil, criminal, administrative, legislative or other (including any
criminal action, suit or proceeding in which such person enters a plea of
guilty or nolo contendere or its equivalent), or any appeal relating thereto,
which is brought or threatened either by or in the right of the Corporation or
such other person, governmental authority or instrumentality (herein called a
"third-party action") and in which such person is made a party or is otherwise
involved by reason of his being or having been such director, officer, employee
or agent or by reason of any action or omission, or alleged action or omission,
by such person in his capacity as such director, officer, employee

                                     II-1
or agent if either (a) such person is wholly successful, on the merits or
otherwise, in defending such derivative or third-party action or (b) in the
judgment of a court of competent jurisdiction or, in the absence of such
determination, in the judgment of a majority of a quorum of the Board of
Directors of the Corporation (which quorum shall not include any director who
is a party to or is otherwise involved in such action) or, in their absence of
such a disinterested quorum, in the opinion of independent legal counsel (i) in
the case of a derivative action, such person acted without negligence or
misconduct in the performance of his duty to the Corporation or such other
company or (ii) in the case of a third-party action, such person acted in good
faith in what he reasonably believed to be the best interests of the
Corporation or such other company and, in addition, in any criminal action, had
no reasonable cause to believe that his action was unlawful, provided that, in
the case of a derivative action, such indemnification shall not be made in
respect of any payment to the Corporation or such other company or any
stockholder thereof in satisfaction of judgment or in settlement unless either
(x) a court of competent jurisdiction has approved such settlement, if any, and
the reimbursement of such payment or (y) if the court in which such action has
been instituted lacks jurisdiction to grant such approval or such action is
settled before the institution of judicial proceedings, in the opinion of
independent legal counsel the applicable standard of conduct specified
hereinbefore has been met, such action was without substantial merit, such
settlement was in the best interests of the Corporation or such other company
and the reimbursement of such payment is permissible under applicable law. In
case such person is successful, on the merits or otherwise, in defending part
of such action or, in the judgment of such a court or such quorum of the Board
of Directors or in the opinion of such counsel, has met the applicable standard
of conduct specified in the preceding sentence with respect to part of such
action, he shall be indemnified by the Corporation against judgments,
settlements, payments, fines, penalties and other costs and expenses
attributable to such part of such action."

ITEM 9.  UNDERTAKINGS

    (a) The undersigned registrant hereby undertakes:

    (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

         (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act;

         (ii) To reflect in the prospectus any facts or events arising after
    the effective date of the Registration Statement (or the most recent
    post-effective amendment thereof) which, individually or in the aggregate,
    represent a fundamental change in the information set forth in the
    Registration Statement;

                                      II-2
(iii) To include any material information with respect to the plan of
    distribution not previously disclosed in the Registration Statement or any
    material change to such information in the Registration Statement;

    provided, however, that paragraphs (a)(l)(i) and (a)(l)(ii) do not apply
    if the information required to be included in a post-effective amendment
    by those paragraphs is contained in periodic reports filed by the
    registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
    that are incorporated by reference in the Registration Statement;

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

    (3) To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of
the offering.

    (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15 (d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in the Registration Statement shall be deemed to be
a new Registration Statement relating to the securities offered therein, and
the offering of such securities at that time shall be deemed to be the initial
bona fide offering thereof.

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