                       REGISTRATION STATEMENT ON FORM S-8

                                     PART I

              INFORMATION REQUIRED IN THE SECTION 10(a) PROSPECTUS

      The documents containing the information specified in Part I of Form S-8
(plan information and registrant information) will be sent or given to employees
as specified by Rule 428(b)(1) of the Securities Act of 1933, as amended (the
"Securities Act"). Such documents need not be filed with the Securities and
Exchange Commission either as part of this Registration Statement or as
prospectuses or prospectus supplements pursuant to Rule 424 of the Securities
Act. These documents and the documents incorporated by reference in this
Registration Statement pursuant to Item 3 of form S-8 (Part II hereof), taken
together, constitute a prospectus that meets the requirements of Section 10(a)
of the Securities Stock.


                                       2


PROSPECTUS

                                 699,000 Shares
                            MILESTONE SCIENTIFIC INC.
                          Common Stock, $.001 Par Value

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

      This Prospectus may be used by certain persons (the "Selling
Stockholders") who may be deemed to be affiliates of Milestone Scientific Inc.,
a Delaware corporation (the "Company"), to sell shares (the "Shares") of Common
Stock, par value $.001 per share, of the Company (the "Common Stock"), which
have been acquired or will be acquired by the Selling Stockholders pursuant to
the exercise of all or any portion of certain stock options granted pursuant to
the Company's 1997 Stock Option Plan (the "Option Plan"), or of certain options
granted to consultants and agents of the Company (the "Consultant Options"),
(the Option Plan and Consultant Options are referred to together as the
"Plans"). It is anticipated that the Selling Stockholders will offer Shares for
sale at prevailing prices on the Nasdaq SmallCap Market or on a principal Stock
Exchange or other National Market Quotation System on the date of sale. All
proceeds from any sale of such Shares will inure to the benefit of the Selling
Stockholders. The Company will receive none of the proceeds from the sale of the
Shares which may be offered hereby, but may receive funds upon the exercise of
stock options pursuant to which the Selling Stockholders will acquire the Shares
covered by this Prospectus, which funds, if any, will be used by the Company for
working capital. All expenses of the registration incurred in connection
herewith are being borne by the Company, but all selling and other expenses
incurred by individual Selling Stockholders will be borne by such Selling
Stockholders.

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

            THE SHARES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK.
                          See "Risk Factors" at page 7.

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

      The Common Stock is traded over-the-counter and is quoted through the
National Association of Securities Dealers Automated Quotation System ("NASDAQ")
on the SmallCap Market System under the symbol "WAND." On November 14, 1997 the
last sales price of the Shares on the NASDAQ SmallCap System was $21.25.

             COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
                 PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY

                The date of this Prospectus is November 17, 1997.

                           FORWARD-LOOKING STATEMENTS

      Certain statements made in or incorporated by reference to this
Registration Statement are "forward-looking statements" (within the meaning of
the Private Securities Litigation Reform Act of 1995) regarding the plans and
objectives of management for future operations. Such statements involve known
and unknown risks, uncertainties and other factors that may cause actual
results, performance or achievements of the Company to be materially different
from any future results, performance or achievements expressed or implied by
such forward-looking statements. The forward-looking statements made in or
incorporated by reference to this Form are based on current expectations that
involve numerous risks and uncertainties. The Company's plans and objectives are
based, in part, on assumptions involving the growth and expansion of business.
Assumptions relating to the foregoing involve judgments with respect to, among
other things, future economic, competitive and market conditions and future
business decisions, all of which are difficult or impossible to predict
accurately and many of which are beyond the control of the Company. Although the
Company believes that its assumptions underlying the forward-looking statements
are reasonable, any of the assumptions could prove inaccurate and, therefore,
there can be no assurance that the forward-looking statements made in or
incorporated by reference to this Form will prove to be accurate. In light of
the significant uncertainties inherent in the forward-looking statements made in
or incorporated by reference to this Form, particularly in view of the Company's
early stage of operations, the inclusion of such information should not be
regarded as a representation by the Company or any other person that the
objectives and plans of the Company will be achieved.


                                       6


                                  RISK FACTORS

      An investment in the Shares offered hereby involves a high degree of risk.
Prospective investors should carefully consider, among other things, the
following factors before a decision is made to purchase any Shares.

      All references in this Registration Statement to the Company refer to
Milestone Scientific Inc. (formerly U.S. Opportunity Search, Inc.), its wholly
owned subsidiaries, Princeton PMC, Inc. ("Princeton PMC") and Sagacity I, Inc.,
doing business in the United States as the Wisdom Toothbrush Co. ("Wisdom"), and
its 69% owned subsidiary, Spintech, Inc. ("Spintech"), unless the context
otherwise indicates.

      Limited Operating History; History of Losses; Accumulated Deficit. The
Company has operated only since November 1995, when it acquired a 65% interest
in Spintech. Since that date, revenues have been limited and were $3,473 for the
fiscal year ended December 31, 1995 and $302,388 for the fiscal year ended
December 31, 1996. Revenues for the nine months ended September 30, 1997 were
$2,305,460 compared to $154,856 for the nine months ended September 30, 1996.
The Company sustained losses of $619,831 and $1,949,528 for the years ended
December 31, 1995 and 1996, respectively, and losses of $1,366,572 and
$3,164,523 for the nine months ended September 30, 1996 and 1997, respectively.
The Company had an accumulated deficit of $5,900,875 at September30, 1997.

      Limited Financial Resources; Need for Additional Financing. The Company's
capital requirements have been and will continue to be significant. The Company
did not operate profitably in 1996 and there can be no assurance that the
Company will be able to generate cash flows in the future which will be
sufficient to fund its operations. Assuming no change in the business operations
of the Company, it is expected that the approximately $10 million proceeds from
the private placement consummated on September 11, 1997 will be sufficient to
meet its working capital requirements until, at least, April 1999. However, no
assurance can be given that the Company's current working capital will be
adequate for its planned operations or that circumstances will not change and
result in the need for additional working capital. If additional financing is
needed, the Company will be required to borrow funds or, sell additional equity
securities, or may be required to curtail or reduce its activities. The Company
has no current arrangements for future additional financing. There can be no
assurance that any sources of additional financing will be available to the
Company on acceptable terms, or at all. To the extent that any future financing
involves the sale of the Company's equity securities, the ownership interest of
the Company's then-stockholders could be substantially diluted.

      Highly Competitive Industry; Technological and Product Obsolescence. The
Company faces intense competition from many companies in the medical and dental
device industry, including well-established academic institutions, possessing
substantially greater financial, marketing, personnel, and other resources. Most
of the Company's competitors have established reputations, stemming from their
success in the development, sale, and service of their competing medical
products. Further, rapid technological change and extensive research and
development characterize the industry. Current or new competitors could, at any
time, introduce new or enhanced products with features that render the Company's
products less marketable, or even obsolete. Therefore, the Company must devote
substantial efforts and financial resources to enhance its existing products, to
bring its developmental products to market, and to develop new products for its
related markets. In order to compete successfully, the Company must establish an
effective distribution network. Several regulatory authorities must also approve
the Company's products before they may be marketed. There can be no 


                                       7


assurance that the Company will be able to compete successfully, that its
competitors will not develop technologies or products that render the Company's
products less marketable or obsolete, or that the Company will be able to
successfully enhance its existing products, effectively develop new products, or
obtain required regulatory approval therefor.

      Integration of Wisdom. Although the Company acquired Wisdom and its United
States distribution system for clinically oriented dental products and Wisdom is
an ongoing business with established revenues, there can be no assurance that
the Company will successfully integrate it into its current operations and
operate it profitably.

      Future Revenue Growth Dependent on Proprietary Products. The Company
believes that its future growth in revenues will be dependent on its proprietary
products, particularly "The Wand(TM)", a computer controlled "painless"
injection system. The Company has had orders placed for "The Wand(TM)" but has
not yet had any sales of this product. The Company's other proprietary products
include the Sharps Disposal System ("SDS") and the "SplatrFree(TM)" disposable
prophy angle. The Company only has had limited sales of the SDS and the
"SplatrFree(TM)" prophy angle. The sale and use of the SDS unit and its
precursor the TAPS unit and the disposal of medical waste after processing by
these units is subject to varying degrees of federal, state, local and foreign
regulation. No assurance can be given that the SDS unit will be available for
sale in a particular jurisdiction or may be used by a purchaser, and no
assurance can be given that the Company will generate any significant revenues
from this product in the future. Further, there can be no assurance that the
Company will be able to successfully market these product lines, that demand
exists at levels or prices at which the Company can operate profitably, or that
the products will meet user expectations. The Company has developed a commercial
version of "The Wand(TM)" and launched this product at the Fall 1997 American
Dental Association Trade Show. No assurance can be given that "The Wand(TM)"
will be successfully marketed by the Company or accepted by the market place.

      Uncertainty of Market Acceptance. Achieving market acceptance for the
Company's proprietary products will require substantial marketing efforts and
expense. As with any new technology, there is substantial risk that the
marketplace will not accept the potential benefits of such technology or be
willing to pay for any cost differential with the existing technologies. Market
acceptance of these current and proposed products will depend, in large part,
upon the ability of the Company to educate potential customers, including
third-party distributors, of the distinctive characteristics and benefits of its
products. There can be no assurance that current or proposed products will be
accepted by the end users or that any of the current or proposed products will
be able to compete effectively against current and alternative products.

      Limited Distribution; Establishing Distribution Channels. The Company has
only a limited number of independent domestic sales representatives and did not
have a direct sales force until its acquisition of Wisdom in December 1996. Its
sales force remains limited. In October 1997, the Company entered into informal
agreements for the distribution of "The Wand(TM)" with Henry Shein, Patterson
Dental, Meer Dental and American Dental Cooperative Member Companies. The
Company has not commenced distribution of the "The Wand(TM)". In December 1996,
the Company began distribution of the SDS and in February 1997 began
distribution of its prophy angles through its Wisdom subsidiary. In addition,
while the Company has an exclusive distribution agreement for the marketing of
the SDS in Taiwan, it does not expect any material sales pursuant thereto until
that system is approved for sale in Taiwan. The Company's future success is
dependent upon its ability to establish an effective sales organization for its
proprietary products or to enter into distribution arrangements 


                                       8


with other entities selling to its target markets. No assurances can be given
that the Company will be able to hire and retain its own sales force or enter
into appropriate distribution arrangements.

      Patent and Intellectual Property Protection. The Company holds U.S.
patents applicable to the SDS and "The Wand(TM)" and has made application for a
U.S. patent on the "SplatrFree(TM)" prophy angle. The Company relies on a
combination of patent, trade secret, and trademark laws and employee and
third-party nondisclosure agreements to protect its intellectual property
rights. Despite the precautions taken by the Company to protect its products,
unauthorized parties may attempt to reverse engineer, copy, or obtain and use
its products and other information the Company regards as proprietary.
Litigation may be necessary to protect the Company's intellectual property
rights and could result in substantial cost to, and diversion of effort by, the
Company with no guarantee of success. The failure of the Company to protect its
proprietary information, and the expense of doing so, could have a material
adverse effect on the Company's operating results and financial condition.
Although the Company has received no claims of infringement, it is possible that
infringement of existing or future patents or proprietary rights of others may
occur. In the event that the Company's products infringe patent or proprietary
rights of others, the Company may be required to modify its processes or to
obtain a license. There can be no assurance that the Company would be able to do
so in a timely manner, upon acceptable terms and conditions, or at all. The
failure to do so would have a material adverse effect on the Company.

      Dependence on Manufacturers. The Company has informal arrangements for the
manufacture of its products by separate domestic manufacturers as follows: SDS
units by Arbutus Electronics, Inc.; SplatrFree(TM) prophy angles by Team
Technologies, Inc.; The Wand(TM) unit and system kit by Tricor Systems, Inc.;
and The Wand(TM) disposable handpiece by Nypro Inc. Termination of the
manufacturing relationship with any of the above manufacturers could
significantly and adversely affect the Company's ability to produce and sell its
products. Though alternate sources of supply exist and new manufacturing
relationships could be established, the Company would need to recover its
existing tools or have new tools produced. Establishment of new manufacturing
relationships could involve significant expense and delay. Any curtailment or
interruptions of the supply, whether or not as a result or termination of the
relationship, would adversely affect the Company.

      Product Liability. The Company is engaged in a business which could expose
it to possible claims for personal injury from the use of its dental and medical
products. The Company maintains liability insurance in the aggregate amount of
$2,000,000 with a per-occurrence limit of $1,000,000 which the Company believes
to be adequate. Although no claims have been made against the Company or any of
the customers using its products, there can be no assurance that such claims
will not arise in the future or that the insurance coverage will be sufficient
to pay such claims. A partially or completely uninsured claim, if successful and
of significant magnitude, could have a material adverse effect on the Company.

      Reliance Upon Management. The Company is dependent upon the personal
efforts and abilities of Leonard Osser, its President and Chief Executive
Officer and Gregory Volok, Executive Vice President and Chief Operating Officer.
Messrs. Osser and Volok have entered into employment agreements with the
Company, as amended, expiring in March 2000 and October 2001, respectively, and
each providing for non-competition periods at the expiration of the terms. The
Company has obtained key man life insurance in the amounts of $3,000,000 and
$1,000,000 on the lives of Messrs. Osser and Volok, respectively. While the
Company expects that such policies will issue in due course, no assurances can
be given that such policies will be obtained.


                                       9


      Litigation; Change in Officers. On April 10, 1997, the Board of Directors
of Spintech terminated the employment of Dr. Ronald Spinello as its Chairman and
Director of Research. The action by the Board follows the bringing by Milestone
and Spintech of legal action against Dr. Spinello in which the plaintiffs seek,
among other things, a declaratory judgment that Dr. Spinello has no personal
rights to certain technology developed while he was employed as Director of
Research of Spintech relating to the design and production of ancillary
components of "The Wand(TM)" and a declaratory judgment that plaintiffs have not
breached Dr. Spinello's employment agreement. Milestone, as principal
stockholder of Spintech, also removed Dr. Spinello and Glenn Spinello as
directors of Spintech. On May 21, 1997, Dr. Spinello filed an Answer and
Counterclaim to the above legal action denying the material allegations of the
complaint and making certain counterclaims, including recovery for breach of Dr.
Spinello's employment agreement. On May 28, 1997, Milestone and Spintech filed a
reply to the counterclaim denying any liability. Milestone has been advised by
its patent counsel that all technology developed by Dr. Spinello while employed
by Spintech is owned by Spintech. Further, the Company believes that ownership
of the technology relating to these ancillary components which are the subject
of this litigation is not required for the manufacture and sale of its
anesthetic delivery system at economically viable prices.

      No Dividends. The Company has never paid a cash dividend on its Common
Stock. Payment of dividends on the Common Stock is within the discretion of the
Board of Directors and will depend upon the Company's earnings, its capital
requirements and financial condition, and other relevant factors. The Company
does not currently intend to declare any dividends on its Common Stock in the
foreseeable future.

      Control by Certain Persons. The Company's officers and the members of its
Board of Directors own approximately 33% of the currently outstanding shares of
Common Stock. Accordingly, by reason of their stockholdings, and their control
of the means for soliciting stockholder votes, the directors will be able to
exercise control of the Company and, in all likelihood, will be able to continue
to elect all directors.

      Limitation of Director Liability. The Company's Certificate of
Incorporation provides that a director of the Company will not be personally
liable to the Company or its stockholders for monetary damages for breach of the
fiduciary duty of care as a director, including breaches which constitute gross
negligence, subject to certain limitations imposed by the Delaware General
Corporation Law. Thus, under certain circumstances, neither the Company nor the
stockholders will be able to recover damages even if directors take actions
which harm the Company.

      Government Regulation and FDA Clearance. The manufacture and sale of the
Company's "SplatrFree(TM)" prophy angles and "The Wand(TM)", are subject to
extensive regulation by the FDA pursuant to the Federal Food, Drug, and Cosmetic
Act ("FDC Act"), and by other federal, state and foreign authorities. Under the
FDC Act, these medical devices must receive FDA clearance before they can be
commercially marketed in the United States. Some products must undergo rigorous
pre-clinical and clinical testing and an extensive FDA approval process before
they can be marketed. These processes can take a number of years and require the
expenditure of substantial resources. The time required for completing such
testing and obtaining such approvals is uncertain, and FDA clearance may never
be obtained. Delays or rejections may be encountered based upon changes in FDA
policy during the period of product development and FDA regulatory review of
each submitted application. Similar delays may also be encountered in other
countries. While the "SplatrFree(TM)" prophy angle and "The Wand(TM)" have
received FDA marketing clearance there can be no assurance that all of the
Company's products under development will obtain the required regulatory
clearance on a timely basis, or at all. If 


                                       10


regulatory clearance of a product is granted, such clearance may entail
limitations on the indicated uses for which the product may be marketed. In
addition, modifications may be made to the Company's products to incorporate and
enhance their functionality and performance based upon new data and design
review. There can be no assurance that the FDA will not request additional
information relating to product improvements, that any such improvements would
not require further regulatory review thereby delaying the testing, approval and
commercialization of the Company's development products or that ultimately any
such improvements will receive FDA clearance. FDA regulations also require
manufacturers of medical devices to adhere to certain "Good Manufacturing
Practices" ("GMP"), which include testing, design, quality control and
documentation procedures. Compliance with applicable regulatory requirements is
subject to continual review and will be monitored through periodic inspections
by the FDA. Later discovery of previously unknown problems with a product,
manufacturer, or facility may result in restrictions on such product or
manufacturer, including fines, delays or suspensions of regulatory clearances,
seizures or recalls of products, operating restrictions and criminal prosecution
and could have a material adverse effect on the Company. See "Business -
Government Regulation."

      Limitation of Tax Loss Carryforward Benefits. As of November 13, 1995,
when the Company acquired a controlling interest in Spintech, the amount of net
operating loss of Spintech available to be carried forward to offset future
taxable income for United States tax purposes ("NOLs") was approximately
$1,890,000. These NOLs expire on various dates through December 31, 2009. The
Company believes that its acquisition of a controlling interest in Spintech
resulted in an "ownership change," as defined in Section 382 of the Internal
Revenue Code of 1986, as amended (the "Code"). As a consequence, the Company
believes that Spintech's NOLs to offset United States taxable income are, in
addition to the carryforward limitations described above, subject to an annual
limitation equal to the fair market value of Spintech immediately before the
ownership change, multiplied by the "long-term tax-exempt rate" as defined in
Section 382 of the Code, or approximately $235,750 per year. The limitation on
the utilization of the NOLs could increase the federal income taxes payable by
the Company if Spintech operates profitably, as to which no assurance can be
given.

      Restricted Securities; Possible Volatility of Market Price; Limited Public
Market Trading. The Common Stock is currently traded on The Nasdaq SmallCap
Market. From time to time the market prices of dental and medical product
companies have been affected by various factors, including adverse publicity.
There can be no assurance that the market price of the Common Stock will not be
volatile as a result of factors such as the Company's financial results,
possible adverse publicity resulting from any infractions of governmental
regulations and various other factors affecting dental and medical product
companies or the market generally. In recent years the stock market has
experienced wide price fluctuations not necessarily related to the operating
performance of such companies. Although the Common Stock has been listed on The
Nasdaq SmallCap Market since November 1995, there can be no assurance that a
regular trading market will be sustained. Further, in order to continue to trade
on The Nasdaq SmallCap Market, the Company must meet The Nasdaq SmallCap
Market's standards for continued listing. If, at any time, the Company's Common
Stock were delisted from The Nasdaq SmallCap Market, the Company's securities
would become subject to the "penny stock rules" applicable to non-Nasdaq
companies whose common stock trades at less than $5.00 per share or which have
tangible net worth of less than $5,000,000 ($2,000,000 if the Company has been
operating for three or more years). Such rules require, among other things, that
brokers who trade "penny stocks" to persons other than "established customers"
complete certain documentation, make suitability inquiries of investors and
provide investors with certain information concerning trading in the security,
including a risk disclosure document and quote information under certain
circumstances. Many brokers have decided not to trade "penny stock" because of
the requirements of 


                                       11


the penny stock rules and, as a result, the number of broker-dealers willing to
act as market makers in such securities is limited.

      Effect of Outstanding Warrants and Options. The Company currently has
outstanding the following options and warrants: (i) warrants to purchase an
aggregate of 80,000 shares of Common Stock at $6.00 per share issued to the
underwriter in the Company's November 1995 public offering and two bridge
lenders (the "1995 Warrants"); (ii) warrants to purchase 482,906 shares of
Common Stock issued to investors in a private placement consummated on March 13,
1997 (the "March Private Placement"); (iii) an option to purchase 85,226 units
(each unit containing one share of Common Stock and one warrant to purchase one
share of Common Stock) granted to GKN Securities Corp., as placement agent (the
"Placement Agent") in the March Private Placement and its designees; (iv)
Warrants to purchase 1,503,666 shares issued to investors in a private placement
consummated in October 1997 (the "October Private Placement"); (v) warrants
issued to Morse, Zelnick, Rose & Lander LLP, counsel to the Company, to purchase
at $6.00 per unit 83,333 units, each unit consisting of one share of Common
Stock and a Warrant to purchase a share of Common Stock at an exercise price of
$9.00; and (vi) incentive and non-qualified stock options issued to officers,
directors and consultants to purchase an aggregate of 699,000 shares of Common
Stock at prices ranging from $5.125 to $7.56 per share expiring on various
dates, the latest of which is July 2002. All of the foregoing securities
represent the right to acquire Common Stock of the Company during various
periods of time and at various prices. Holders of all the foregoing securities
are given the opportunity to profit from a rise in the market price of the
Common Stock and are likely to exercise their securities at a time when the
Company would be able to obtain additional equity capital on more favorable
terms. Thus, the terms upon which the Company will be able to obtain additional
equity capital may be adversely affected since the holders of outstanding
options and warrants can be expected to exercise them at a time when the Company
would, in all likelihood, be able to obtain any needed capital on terms more
favorable to the Company than the exercise terms provided by such outstanding
securities. The Company has not granted any registration rights with respect to
any shares of Common Stock or other securities that are "restricted securities"
or that underlie outstanding warrants or options, other than the registration
rights granted to investors in the October Private Placement, the March Private
Placement, to the Placement Agent and to the holders of the 1995 Warrants.

                                 USE OF PROCEEDS

      The Company will not receive any proceeds from the sale of the Shares by
the Selling Stockholders, but may receive funds upon the exercise of stock
options pursuant to which the Selling Stockholders will acquire Shares covered
by this Prospectus, which funds, if any, will be used by the Company for working
capital.

                               RECENT DEVELOPMENTS

Private Offering

      On September 11, 1997, the Company completed a $10 million private equity
offering (the "Private Placement") to 36 accredited investors of 1,666,666 units
(the "Units"). The per-Unit offering price was $6.00, and each Unit consisted of
one share of Common Stock and one warrant to purchase one share of Common Stock
at an exercise price of $9.00 per share until September 10, 1999. In connection
with the Private Placement, the Company issued to its counsel warrants to
purchase 83,333 units, exercisable at $6.00 per unit, each unit consisting of
one share of Common Stock and a warrant to purchase one share of Common Stock at
an exercise price of $9.00.

                ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS

      Sections 145 of the Delaware General Corporation Law grants to the Company
the power to indemnify the officers and directors of the Company, under certain
circumstances and subject to certain conditions and limitations as stated
therein, against all expenses and liabilities incurred by or imposed upon them
as a result of suits brought against them as such officers and directors if they
act in good faith and in a manner they reasonably believe to be in or not
opposed to the best interests of the Company and, with respect to any criminal
action or proceeding, have no reasonable cause to believe their conduct was
unlawful.

      The Company's certificate of incorporation provides as follows:

      "NINTH: A director of the Corporation shall not be personally liable to
the Corporation or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit.

      TENTH: (a) Right to Indemnification. Each person who was or is made a
party or is threatened to be made a party to or is involved in any action, suit
or proceeding, whether civil, criminal, administrative or investigative
(hereinafter a "proceeding"), by reason of the fact that he or she, or a person
of whom he or she is the legal representative, is or was a director or officer,
of the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation or of a partnership,
joint venture, trust or other enterprise, including service with respect to
employee benefit plans, whether the basis of such proceeding is alleged action
in an official capacity as a director, officer, employee or agent or in any
other capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by the Corporation to the fullest extent
authorized by the General Corporation Law, as the same exists or may hereafter
be amended (but, in the case of any such amendment, only to the extent that such
amendment permits the Corporation to provide broader indemnification rights than
said law permitted the Corporation to provide prior to such amendment), against
all expense, liability and loss (including attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid or to be paid in settlement)
reasonably incurred or suffered by such person in connection therewith and such
indemnification shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of his or her heirs,
executors and administrators; provided, however, that, except as provided in
paragraph (b) hereof, the Corporation shall indemnify any such person seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such person only if such proceeding (or part thereof) was authorized by the
Board of Directors of the Corporation. The right to 


                                       18


indemnification conferred in this Section shall be a contract right and shall
include the right to be paid by the Corporation the expenses incurred in
defending any such proceeding in advance of its final disposition; provided,
however, that, if the General Corporation Law requires, the payment of such
expenses incurred by a director or officer (in his or her capacity as a director
or officer and not in any other capacity in which service was or is rendered by
such person while a director or officer, including, without limitation, service
to an employee benefit plan) in advance of the final disposition of a
proceeding, shall be made only upon delivery to the Corporation of an
undertaking, by or on behalf of such director or officer, to repay all amounts
so advanced if it shall ultimately be determined that such director or officer
is not entitled to be indemnified under this Section or otherwise. The
Corporation may, by action of its Board of Directors, provide indemnification to
employees and agents of the Corporation with the same scope and effect as the
foregoing indemnification of directors and officers.

      (b) Right of Claimant to Bring Suit. If a claim under paragraph (a) of
this Section is not paid in full by the Corporation within thirty days after a
written claim has been received by the Corporation, the claimant may at any time
thereafter bring suit against the Corporation to recover the unpaid amount of
the claim and, if successful in whole or in part, the claimant shall be entitled
to be paid also the expense of prosecuting such claim. It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses
incurred in defending any proceeding in advance of its final disposition where
the required undertaking, if any is required, has been tendered to the
Corporation) that the claimant has not met the standards of conduct which make
it permissible under the General Corporation Law for the Corporation to
indemnify the claimant for the amount claimed, but the burden of proving such
defense shall be on the Corporation. Neither the failure of the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) to have made a determination prior to the commencement of such
action that indemnification of the claimant is proper in the circumstances
because he or she has met the applicable standard of conduct set forth in the
General Corporation Law, nor an actual determination by the Corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) that the claimant has not met such applicable standard or conduct,
shall be a defense to the action or create a presumption that the claimant has
not met the applicable standard of conduct.

      (c) Non-Exclusivity of Rights. The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in this Section shall not be exclusive of any other right
which any person may have or hereafter acquire under any statute, provision of
the Certificate of Incorporation, by-law, agreement, vote of stockholders or
disinterested directors or otherwise.

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