Item 2.       Acquisition of Assets

         On December 20, 1996, Alcohol Sensors International, Ltd. ("ASI")
entered into and consummated an agreement with American International Insurance
Company, a subsidiary of American International Group, whereby ASI received
$2,500,000 in exchange for the issuance of 833,333 shares of Series A
Convertible Preferred Stock (the "Series A Preferred Stock") and 833,333
Warrants, pursuant to a Convertible Stock and Warrant Purchase Agreement, a
copy of which is annexed hereto as exhibit 1.

         Other documents which were executed as part of this transaction
include a Registration Rights Agreement, Shareholders Agreement and Warrant
Certificate, copies of which are annexed hereto as exhibits 2, 3 and 4
respectively.

         In addition, copies of the Certificate of Amendment to the Certificate
of Incorporation, creating the aforementioned Series of Preferred Stock, is
attached hereto as exhibit 5.

         Pursuant to the terms of the Series A Stock and Warrant Purchase
Agreement, American International Insurance Company purchased 833,333 shares of
Series A Convertible Preferred Stock, and 833,333 Common Stock Purchase
Warrants for $2,500,000.

         Pursuant to the terms of the documents, the Stated Value of the Shares
of Series A Preferred Stock is $3.00 per share. The Series A Preferred Stock is
convertible at the option of the holder at a conversion price per share equal
to $4.50, subject to adjustment. Upon conversion of the Series A Preferred
Stock in full, 555,556 shares of Common Stock , par value $.001 per share,
would be issued.

         In addition, the Series A Preferred Stock contains an automatic
conversion feature, pursuant to which the number of fully paid and
nonassessable shares of Common Stock into which such shares of Series A
Preferred Stock would have been convertible in the event of the heretofore
described optional conversion. This automatic conversion shall occur upon the
twentieth day during any period of thirty consecutive days on which the closing
price is at least $8.00 per share.

         ASI shall accrue to holders of the Series A Preferred Stock cash
dividends at the rate of 9% per annum (compounded semi-annually) on such
shares, whether or not declared, that remain unpaid beyond the next succeeding
dividend payment date; provided, however, that ASI, shall, at its option, be
entitled to issue additional shares of Series A Preferred Stock in lieu of cash
in respect of dividends payable on or prior to the first four dividend payment
dates occurring after the initial issuance date. The Dividends shall be payable
semi-annually in arrears when declared by the Board of Directors of the
Corporation, on June 30 and December 31 of each year.

<PAGE>

         Pursuant to the terms of the Convertible Preferred Stock and Warrant
Purchase Agreement, ASI issued 833,333 Common Stock Purchase Warrants. Each
Warrant entitles the holder thereof to purchase from ASI, at any time prior to
5:00 p.m., New York City time, on December 20, 1998, one duly authorized,
validly issued, fully paid and non assessable share of the Common Stock, par
value $.001 per share ("Common Stock"), of the Company (ASI), at a purchase
price of $5.50 per share, subject to the terms and conditions contained within
the Warrant Certificate.

         Also executed in conjunction with this transaction was a Shareholders
Agreement among ASI, American International Insurance Company and members of
ASI's management. Pursuant to the terms of such Shareholders Agreement, the
holders of the Series A Preferred Stock, voting separately as a class, shall
have the exclusive right to elect one director to the Board of Directors of ASI
as long as at least 250,000 shares of Series A Preferred Stock are outstanding.
This exclusive right to elect one director shall remain in effect if, at any
time, less than 250,000 shares of Series A Preferred Stock are outstanding (as
adjusted for stock splits, stock dividends, stock combinations,
recapitalizations and like occurrences), but American International Insurance
Company then holds in excess of 166,666 shares of Common Stock (as adjusted for
stock splits, stock dividends, stock combinations, recapitalization and like
occurrences.)

         Other terms included in the Shareholders Agreement contain a
restricted period, for a term of two years, within which the Existing
Shareholders ( management) agree with the Company (ASI) and American
International Insurance Company, and with each other Shareholder, that they
will not, directly or indirectly, transfer any Capital Stock of the Company,
except for certain exceptions as listed in the Shareholders Agreement.

         The Shareholders Agreement also provides to American International
Insurance Company, a right of first refusal to purchase a pro rata share of new
securities that the Company may, from time to time, propose to sell and issue.

         Additionally, the Registration Rights Agreement provided American
International Insurance Company, with the right to request ASI to effect the
registration under the Securities Act of Registrable Securities.

         In addition, a Certificate of Amendment to the Certificate of
Incorporation of ASI was previously filed authorizing the Company to issue
3,000,000 Convertible Preferred Shares. At the closing of this transaction, a
subsequent Certificate of Amendment was executed and filed, designating 833,333
shares as Series A Preferred Stock.

         As previously indicated, copies of all documents executed pursuant to
the aforementioned transaction, have been annexed as exhibits. The foregoing
descriptions of such documents are summaries only and qualified in their
entirety by reference to such documents, each of which has been filed as an
exhibit hereto.

every jurisdiction in which the conduct of its business or the ownership or
leasing of its properties requires it to be so qualified or licensed, except

and correct copies of the Certificate of Incorporation and by-laws of the
Company and each Subsidiary, each as currently in effect, and no action has
been taken or authorized to amend or in contemplation

and other documents required to be filed by it with the Commission pursuant to
the Exchange Act and the Securities Act, true, correct and complete copies of
which (other than preliminary materials and exhibits) have been provided to the
Purchaser by the Company. The Company shall timely file with the Commission and
promptly provide the Purchaser with a true, correct and complete copy of any
such forms, reports and other documents required to be filed with the
Commission on or prior to the Closing Date. All such forms, reports and
documents filed from November 9, 1995 through the Closing Date are referred to
herein as the "SEC Documents." Each of the SEC Documents (i) was or, as to
documents not yet filed at the date of this Agreement, will be prepared in
accordance with the requirements of the Securities Act or the Exchange Act, as
the case may be, in all material respects and (ii) did not, or as to documents
not yet filed at the date of this Agreement, will not, as of its date, contain
any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements made
therein, in the light of the circumstances under which they were made, not
misleading. The Confidential Memorandum did not, as of the date thereof, and,
as of the Closing Date, will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements made therein, in light of the
circumstances under which they were made, not misleading.

         Section 3.9. Financial Statements, Projections, etc. The consolidated
financial statements of the Company and the Subsidiaries (including any notes
thereto) contained in the SEC Documents were prepared in accordance with
generally accepted accounting principles applied on a consistent basis
throughout the periods indicated (except as indicated in the notes thereto or
as otherwise permitted by the Commission with respect to the omission of
certain note and other disclosures in interim financial statements) and each
fairly presents the consolidated financial position, results of operations and
cash flows of the Company and the Subsidiaries as at the respective dates
indicated therein and for the respective periods indicated therein (subject, in
the case of unaudited statements, to normal and recurring year-end adjustments
which were

                                      -8-
<PAGE>

not and are not expected, individually or in the aggregate, to be material in
amount). Neither the Company nor any Subsidiary has any debts, obligations or
liabilities of any nature, whether accrued, absolute, contingent or otherwise,
and whether due or to become due, probable of assertion or not, that are
required to be disclosed in accordance with generally accepted accounting
principles other than those reflected or disclosed in the Balance Sheet and the
notes thereto and those incurred after the date of the Balance Sheet in the
ordinary course of business. The financial projections in relation to the
Company provided to the Purchaser prior to the date hereof were prepared in
good faith and on the basis of the assumptions set forth therein, which the
Company believes are reasonable.

except, as otherwise set forth in (i) the Company's Annual Report on Form 10-K
for the fiscal year ended December 31, 1995 and the Company's Quarterly Reports
on Form 10-Q for the respective quarterly periods ended March 31, 1996 and June
30, 1996 or (ii) Schedule 3.10 hereto, in each case as filed with the
Commission, each of the Company and each Subsidiary has conducted its business

and without limiting the generality of the foregoing, there has not been:

            (a) Any change, occurrence or circumstance in or affecting the

the Company or any Subsidiary that has had or may reasonably be expected to
have a Material Adverse Effect on the Company;

            (b) Any resignation or termination of any key officers, employees

<PAGE>

            (g) Any material change in any compensation arrangement or
agreement with any employee, consultant, officer, director or shareholder;

distribution of the assets of the Company or any of the Subsidiaries or any
direct or indirect redemption, purchase, retirement or other acquisition of any
shares of its capital stock;

            (i) Any debt, obligation or liability incurred, assumed or
guaranteed by the Company or any of the Subsidiaries, except those for
immaterial amounts or for current liabilities incurred in the ordinary course
of business;

            (j) Any sale, assignment or transfer of any of the assets or rights
of the Company or any Subsidiary (other than the sale of their respective
inventory in the ordinary course of business), including patents, trademarks,
copyrights, trade secrets or other intangible assets or intellectual property,
or any mortgage or pledge of or Lien imposed upon any of the assets or
properties of the Company or any Subsidiary, except in the ordinary course of

Company and each of the Subsidiaries is, and their business has been operated,
in compliance with their respective organizational documents and all applicable
laws, rules, regulations, decrees, injunctions, judgments, orders, rulings,
awards, settlements and writs, except where the failure to comply therewith
would not, individually or in the aggregate, have a Material Adverse Effect on
the Company.

         Section 3.12. Taxes. "Taxes" shall mean all taxes, charges, fees,
Liens, duties or other assessments, however denominated, including any interest
or penalties that may become payable in respect thereof, imposed by the United
States government, any state, local or foreign government or any agency or
political subdivision of any such government (a "Tax Authority"),

                                      -10-
<PAGE>

which taxes shall include, without limiting the generality of the foregoing,
all income taxes, payroll and employee withholding taxes, unemployment
insurance, social security, sales and use taxes, excise taxes, capital taxes,
franchise taxes, gross receipt taxes, occupation taxes, real and personal
property taxes, value added taxes, stamp taxes, transfer taxes, workers'
compensation taxes and other obligations of the same or of a similar nature.
All tax returns or reports required to be filed by or on behalf of the Company
or any Subsidiary have been timely filed or requests for extensions have been
timely filed and, to the best knowledge of the Company, any such extension has
been granted and has not expired, and all such filed returns are complete and
accurate. All Taxes due from the Company or any Subsidiary for periods through
the Closing Date have been paid in full or an adequate provision has been made
for any such Taxes on the financial statements included in the Quarterly Report
(in accordance with generally accepted accounting principles). There is no
audit, examination, deficiency, or refund litigation pending or threatened,
with respect to any Taxes of the Company or any Subsidiary that could result in
a determination that would have a Material Adverse Effect on the Company. All
Taxes, interest, additions and penalties due with respect to completed and
settled examinations or concluded litigation relating to it have been paid in
full or adequate provision has been made for any such Taxes on the financial
statements included in the Quarterly Report (in accordance with generally
accepted accounting principles). The Company has not executed an extension or
waiver of any statute of limitations on the assessment or collection of any Tax
that is currently in effect. No rulings have been issued by or agreements
entered into with any Tax Authority with respect to the Company or any
Subsidiary.

         Section 3.13. ERISA and Employee Benefit Plans. Except as listed in
Schedule 3.13, neither of the Company nor any Subsidiary maintains, sponsors,
is required to make contributions to or otherwise has any liability, direct,
indirect, contingent or otherwise, with respect to any pension, profit sharing,
thrift or other retirement plan, employee stock ownership plan, deferred
compensation, stock ownership, stock purchase, performance share, bonus or
other incentive plan, severance plan, health or group insurance plan, welfare
plan, or other similar plan, agreement, policy, arrangement or understanding,
whether written or oral, whether or not such plan is intended to be qualified
under Section 401(a) of the Code, including any employee benefit plan within
the meaning of Section 3(3) of ERISA, which plan covers any employee or former
employee of the Company or any Subsidiary (collectively, the "Plans"). The
Company has delivered to the Purchaser true, correct and complete copies of (i)
any employment agreements and any procedures and policies (including summaries
of any procedures and policies that are unwritten) relating to the employment
of employees of the Company and each Subsidiary and the use of temporary
employees and independent contractors by the Company and each Subsidiary, (ii)
each Plan and all related trust agreements, insurance and other material
contracts, and summary plan descriptions and summaries of material
modifications relating to each Plan and any related material communications
distributed to participants under the Plans and (iii) the latest reports which
have been filed (or are in fully completed form for filing) with the Internal
Revenue Service and the Department of Labor with respect to each Plan. No Plan
is subject to Title IV of ERISA. With respect to each Plan, to the best
knowledge of the Company, no party in interest or disqualified person (as
defined in Section 3(14) of ERISA

                                      -11-
<PAGE>

and Section 4975 of the Code, respectively) has at any time engaged in a
transaction which could subject the Company or any of the Subsidiaries,
directly or indirectly, to a Tax, penalty or liability for prohibited
transactions imposed by ERISA or Section 4975 of the Code. To the best
knowledge of the Company, no fiduciary (as defined in Section 3(21) of ERISA)
with respect to any Plan has breached any of the responsibilities or
obligations imposed upon fiduciaries under Title I of ERISA. Each Plan is and
has been operated in compliance in all material respects with its terms and all
applicable reporting, disclosure and other requirements of ERISA and the Code
as they relate to such Plan, including where applicable the group health plan
continuation coverage requirements set forth in Part 6 of Subtitle B of Title I
of ERISA and Section 4980B of the Code, and by its terms can be terminated at
any time. As of the Closing Date, the Company and each Subsidiary shall have
made all required contributions under each Plan for all periods through and
including the Closing Date or adequate accruals therefor will have been
provided for by the Company or such Subsidiary. No Person will be entitled to
any severance benefits under the terms of any Plan solely by reason of the
transactions contemplated by this Agreement, the Registration Rights Agreement,
the Warrant Certificate or the Shareholders Agreement. There are no actions,
claims, lawsuits or arbitrations pending or, to the best knowledge of the
Company, threatened with respect to any Plan. No Plan provides for the payment
of retiree or post-termination medical, health, disability, life insurance or
other welfare benefits. Neither the Company nor any of the Subsidiaries has or
has ever had any ERISA Affiliate. For purposes of this Agreement, "ERISA
Affiliate" means any Person which would be treated as a single employer with
the Company or any Subsidiary under Section 414(b), (c), (m) or (o) of the Code
and the regulations promulgated thereunder or Title IV of ERISA. Neither the
Company nor any Subsidiary has incurred any liability to the Pension Benefit
Guaranty Corporation. Each Plan which is intended to be "qualified" within the
meaning of Section 401(a) of the Code (and the exempt trust thereunder), has
been determined by the Internal Revenue Service to satisfy the qualification
requirements of Sections 401(a) and 501(a) of the Code and every Plan (and
related trust) which is intended to comply with the terms and requirements of
applicable statutes does so comply in all material respects. Each of the
Company and each Subsidiary has never contributed to, or withdrawn in a
complete or partial withdrawal from, any multiemployer plan (within the meaning
of Subtitle E of Title IV of ERISA) or incurred contingent liability under
Section 4204 of ERISA. Neither the Company nor any Subsidiary has proposed or
agreed to any increase in benefits under any Plan (or the creation of new
benefits) or change in employee coverage which would increase the expense of
maintaining any such Plan. The consummation of the transactions contemplated by
this Agreement and the Registration Rights Agreement, the Warrant Certificate
and the Shareholders Agreement will not result in an increase in the amount of
compensation or benefits or accelerate the vesting or timing of payment of any
benefits or compensation payable in respect of any employee.

         Section 3.14. Contracts, etc. Neither the Company nor any of the
Subsidiaries, nor to the best knowledge of the Company any other party thereto,
is in default or breach (and there is no event which, with notice or lapse of
time or both, would constitute such a default or breach) under any agreement,
arrangement, bond, commitment, contract, franchise, indemnity,

                                      -12-
<PAGE>

indenture, instrument, lease, license or understanding, whether or not in
writing, to which it is a party or to which any of its assets are subject, in
each case that has had or may reasonably be expected to have a Material Adverse
Effect on the Company.

         Section 3.15. Legal Proceedings, etc. (i) There is no legal,
administrative, arbitral or other investigation, claim, action or proceeding
pending or, to the best knowledge of the Company, threatened against the
Company or any of the Subsidiaries or any of their respective directors,
officers or employees or to which any of their properties are subject or
against any Plan or the trustee of any Plan which challenges the validity of
this Agreement, the Registration Rights Agreement, the Warrant Certificate, the
Shareholders Agreement, the Certificate of Amendment, the Preferred Stock, the
Warrants or any action taken or to be taken pursuant hereto or thereto, which
seeks to impose or confirm any limitation on the ability of the Purchaser
effectively to acquire, hold or exercise full rights of ownership of the
Preferred Shares, the Warrants or the Common Shares, or, except as disclosed on
Schedule 3.15 hereto, which in the aggregate with all other such
investigations, claims, actions and proceedings would have a Material Adverse
Effect on the Company; (ii) neither the Company nor any Subsidiary is a party
or is subject to the provisions of any order, writ, injunction, award,
settlement, judgment or decree of any court, board or other governmental agency
or instrumentality or administrative agency or any arbiter, which would,
individually or in the aggregate, have a Material Adverse Effect on the
Company; and (iii) there is no action, suit, proceeding or investigation by the
Company or any Subsidiary currently pending or which the Company or any
Subsidiary intends to initiate.

         Section 3.16. Brokerage. No placement agent, banker, broker or finder
has acted directly or indirectly for the Company in connection with this
Agreement or the transactions contemplated hereby, and no placement agent,
banker, broker or finder is entitled to any commission, brokerage or finder's
fee in respect thereof based in any way on agreements, arrangements or
understandings made by or on behalf of the Company.

         Section 3.17. Agreements; Action. (a) Except as otherwise disclosed in
Schedule 3.17 hereto, there are no agreements, understandings, instruments,
contracts, proposed transactions, judgments, orders, injunctions, awards,
settlements, writs or decrees to which the Company or any Subsidiary is a party
or by which it is bound which may involve or contain (i) obligations
(contingent or otherwise) of, or payments to, the Company or any Subsidiary in
excess of $50,000 (other than obligations of, or payments to, the Company or
any Subsidiary arising from purchase or sale agreements entered into in the
ordinary course of business), (ii) the license of any patent, copyright, trade
secret or other proprietary right to or from the Company (other than licenses
arising from the purchase of "off the shelf" or other standard products), (iii)
provisions restricting or affecting the development, manufacture or
distribution of the Company's or any Subsidiary's products or services or (iv)
indemnification by the Company or any Subsidiary with respect to infringements
of proprietary rights (other than indemnification obligations arising from
purchase or sale agreements entered into in the ordinary course of business).

                                      -13-

            (b) Since December 31, 1995, neither the Company nor any Subsidiary
has incurred any indebtedness for money borrowed or any other liabilities
(other than with respect to obligations incurred in the ordinary course of
business) individually in excess of $50,000 or, in the case of indebtedness
and/or liabilities individually less than $50,000, in excess of $250,000 in the
aggregate.

            (c) For the purposes of subsections (a) and (b) above, all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same Person (including Persons the
Company has reason to believe are affiliated therewith) shall be aggregated for
the purpose of meeting the individual minimum dollar amounts of such
subsections.

            (d) Neither the Company nor any Subsidiary has engaged in the past
three (3) months in any discussion (i) with any Person or any representative of
such Person regarding the consolidation or merger of the Company or any
Subsidiary with or into any such Person or another Person, (ii) with any Person

         Section 3.19. Title to Properties and Assets; Liens, etc. Each of the
Company and each Subsidiary has good and marketable title to its properties and
assets, and good title to its leasehold estates, in each case subject to no
Lien, other than (i) those identified on the Balance Sheet, (ii) those
resulting from taxes which have not yet become delinquent, (iii) minor Liens
which do not materially detract from the value of the property or materially
impair the operations of the Company or such Subsidiary and (iv) those that
have otherwise arisen in the ordinary course of business. All facilities,
machinery, equipment, fixtures, vehicles and other properties owned, leased or
used by the Company and each Subsidiary are in good operating condition and
repair and are reasonably fit and usable for the purposes for which they are
being used. Schedule 3.19 hereto sets forth a true, complete and correct list
of all of the real property that is leased to the Company and each Subsidiary.
The Company and each Subsidiary enjoys peaceful and undisturbed possession of
all such real property leased to it. Neither the Company nor any Subsidiary has
ever owned or presently owns any real property. The Company has never
manufactured or produced, and does not presently manufacture or produce, any of
its products or goods; except as set forth on Schedule 3.19, such products and
goods have been and are presently manufactured and produced by independent
third Persons.

         Section 3.20. Patents and Trademarks. Each of the Company and each
Subsidiary owns or possesses sufficient legal rights to all trademarks, service
marks, trade names, copyrights, trade secrets, patents, information, other
proprietary rights and processes necessary for its business as now conducted
and as proposed to be conducted, without any known infringement of the rights
of others. There are no outstanding options, licenses or agreements of any kind
relating to the foregoing, nor is the Company or any Subsidiary bound by or a
party to any options, licenses or agreements of any kind with respect to the
trademarks, service marks, trade names, copyrights, trade secrets, patents,
licenses, information and other proprietary rights and processes of any other
Person other than such licenses or agreements arising from the purchase of "off
the shelf" or standard products. Each of the Company and each Subsidiary has
not received any communications alleging that the Company or any Subsidiary has
violated or, by conducting its business as proposed, would violate any of the
trademarks, service marks, trade names, copyrights, trade secrets, patents or
other proprietary rights of any other Person. Each of the Company and each
Subsidiary is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or other
agreement, or subject to any judgment, decree, injunction, award, settlement or
order of any court or administrative agency, that would interfere with his or
her duties to the Company or any Subsidiary or that would conflict with the
Company's or any Subsidiary's business as presently conducted and as proposed
to be conducted.

         Section 3.21. Employees. Each of the Company and each Subsidiary has
no collective bargaining agreements with any of its employees. There is no
labor union organizing activity pending or, to the Company's best knowledge,
threatened with respect to the Company or any Subsidiary. To the Company's best
knowledge, no employee of the Company or any Subsidiary, nor any consultant
with whom the Company or any Subsidiary has contracted, is in violation of any
term of any employment contract, proprietary information agreement or any

                                      -15-
<PAGE>

other agreement relating to the right of any such individual to be employed by,
or to contract with, the Company or such Subsidiary because of the nature of
the business to be conducted by the Company or such Subsidiary; and, to the
Company's best knowledge, the continued employment by the Company and each
Subsidiary of its present employees, and the performance of the Company's and
each Subsidiary's contracts with its independent contractors, will not result
in any such violation. The Company and the Subsidiaries have not received any
notice alleging that any such violation has occurred. Except as set forth in
Schedule 3.21 hereto, no employee or consultant of the Company or of any
Subsidiary has been granted the right to continued employment by the Company or
such Subsidiary or to any material compensation following termination of
employment with or by the Company or such Subsidiary.

         Section 3.22. Permits. Each of the Company and each Subsidiary has all
franchises, permits, licenses, consents and approvals and any similar
authority, all of which are in full force and effect, necessary for the conduct
of its business as now being conducted by it, the lack of which would have a
Material Adverse Effect on the Company.

         Section 3.23. Environmental Matters. As used herein, "Subject
Premises" means the real property now owned, operated, used or leased or
previously owned, operated, used or leased (but only through the date of
termination of such ownership, operation, use or lease) by, to or for the
Company or the Subsidiaries or any of their Affiliates. (i) To the best
knowledge of the Company, none of the Subject Premises has any condition or
conditions which would require notification or remediation under any

Environmental Laws and Environmental Permits (as defined below); (iv) neither
the Company nor any of the Subsidiaries has received any letter or other

Agency or any other local, state or Federal regulatory agencies or any other
Person relating to the existence of Environmental Defects at the Subject
Premises; (v) to the best knowledge of the Company, there do not exist any
judgments, orders, directives, decrees or awards of any court, arbitrator or
administrative or governmental agency or entity or any other Person concerning
the Company or any of the Subsidiaries or any of their agents' or contractors'
compliance with any Environmental Law or Environmental Permit (in the case of
agents and contractors, relating to the Company, any of the Subsidiaries or the
Subject Premises); (vi) no claims have been asserted or, to the best knowledge
of the Company, are threatened against the Company or any of the Subsidiaries
relating to any Environmental Defect or condition which with the passage of
time could become an Environmental Defect; (vii) to the best knowledge of the
Company, there do not exist any consent decrees, administrative orders,
settlement agreements or other settlement documents entered into with any

Company, there are no Hazardous Substances or Hazardous Waste on, under or
about the Subject Premises other than those customarily used in or incident to
the business of the Company or any Subsidiary, which in any event are used or
maintained in all material respects in accordance with all applicable
Environmental Laws and Environmental Permits. For purposes hereof, "Hazardous

         Section 3.24. Offering Valid. Assuming the accuracy of the
representations and warranties of the Purchaser contained in Article IV hereof,
the offer, sale and issuance of the Preferred Shares, the Warrants and the

Warrants, as applicable, will be exempt from the registration requirements of
the Securities Act and will have been registered or qualified (or are exempt
from registration and qualification) under the registration, permit or

Preferred Shares or Warrants to any Person or Persons or has taken or will take
any other action so as to bring the sale of such Preferred Shares, Warrants or

to the Company's best knowledge, omit to state a material fact necessary in
order to make the statements contained herein or therein in light of the
circumstances under which they were made not misleading. To the Company's best

         Section 4.1. Organization, Existence and Authority of Purchaser;
Enforceability. The Purchaser is a corporation duly incorporated, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation. The Purchaser has all necessary corporate power and authority to
execute and deliver this Agreement, the Registration Rights Agreement and the
Shareholders Agreement, to consummate the transactions contemplated hereby and
thereby and to perform its obligations hereunder and thereunder. The execution
and delivery by the Purchaser of this Agreement, the Registration Rights
Agreement and the Shareholders Agreement, and the performance of its
obligations hereunder and thereunder, have been duly authorized by all
necessary corporate and other action, and no further authorization on the part
of the Purchaser is necessary to authorize such execution, delivery and
performance. This Agreement has been, and the Registration Rights Agreement and
the Shareholders Agreement when executed and delivered by the Purchaser will
be, duly executed and delivered by the Purchaser. This Agreement constitutes,
and the Registration Rights Agreement, the Warrant Certificate and the
Shareholders Agreement, when so executed and delivered, will constitute, legal,
valid and binding agreements of the Purchaser, enforceable against the
Purchaser in accordance with their respective terms, except as enforceability
may be subject to the application of general equitable principles and to
bankruptcy, insolvency, moratorium or other similar laws affecting creditors'
rights generally.

         Section 4.2. No Consent or Violation. No consent, approval or
authorization of, or declaration, filing or registration with, any governmental
or regulatory authority is required in connection with the execution and
delivery by the Purchaser of this Agreement, the Registration Rights Agreement,
the Warrant Certificate and the Shareholders Agreement, the consummation of the
transactions contemplated hereby and thereby and the performance by the
Purchaser of its obligations hereunder and thereunder. The execution and
delivery by the Purchaser of this Agreement, the Registration Rights Agreement,
the Warrant Certificate and the Shareholders Agreement, the consummation of the
transactions contemplated hereby and thereby and the performance by the
Purchaser of its obligations hereunder and thereunder do not and will not (with
the giving of notice or the passage of time or both) (a) conflict with or
violate or result in a breach of or constitute a default under, or result in
any right of termination by any other Person or the creation of any Lien upon
any properties or assets of the Purchaser pursuant to: (i) the organizational
documents of the Purchaser or (ii) any material note, bond, mortgage,
indenture, deed of trust, license, franchise, permit, lease, contract,
agreement or other

are bound or (b) violate any applicable law, rule, regulation, judgment,
injunction, order or decree binding upon the Purchaser or to which any of its
properties is subject.

         Section 4.3. Purchase for Own Account. The Preferred Shares and the
Warrants to be acquired by the Purchaser pursuant to this Agreement will be
acquired for its own account for investment purposes and not with a view to the
resale or distribution of any part thereof.

         Section 4.4 Restricted Securities. The Purchaser understands that the
Preferred Shares and the Warrants being acquired pursuant hereto are
characterized as "restricted securities" under the Federal and state securities
laws inasmuch as they are being acquired from the Company in a transaction not
involving a public offering and that under such laws and applicable regulations
such securities may be resold without registration under the Securities Act and
applicable state securities laws only in certain limited circumstances. The
Purchaser is familiar with Rule 144 ("Rule 144") of the Commission, as
presently in effect, and understands the resale limitations imposed thereby and
by the Securities Act and applicable state securities laws, pursuant to which
the Preferred Shares and the Warrants (and the Common Shares issuable upon
conversion of the Preferred Shares or exercise of the Warrants) must be held
indefinitely unless a subsequent disposition thereof is registered under the
Securities Act and applicable state securities laws or is exempt from such
registration.

         Section 4.5. Accredited Investor. The Purchaser is an "accredited
investor" within the meaning of Rule 501(a) of Regulation D, promulgated under
the Securities Act, and was not organized for the specific purpose of acquiring
the Preferred Shares and the Warrants.

         Section 4.6. Investor Sophistication. The Purchaser, by reason of its
business and financial experience, has such knowledge, sophistication and
experience in business and financial matters as to be capable of evaluating the
merits and risks of the prospective investment and is able to bear the economic
risk of such investment.

         Section 4.7. Brokerage. No placement agent, banker, broker or finder
has acted directly or indirectly for the Purchaser in connection with this
Agreement or the transactions contemplated hereby, and no placement agent,
banker, broker or finder is entitled to any commission, brokerage or finder's
fee in respect thereof based in any way on agreements, arrangements or
understandings made by or on behalf of the Purchaser.


                                   ARTICLE V
                               CERTAIN COVENANTS

capital needs.

         Section 5.2. Certain Actions. From the date hereof through the Closing
Date, the Company (i) shall not, and shall cause each Subsidiary not to, take
any action that would cause any of the representations or warranties of the
Company set forth herein to become untrue or misleading and (ii) shall not take
any action which if taken after the Closing Date would require adjustment of
the conversion price of the Preferred Shares, adjustment of the exercise price
of the Warrants or adjustment of the number of Common Shares issuable upon
conversion of the Preferred Shares pursuant to the Certificate of Amendment or
upon exercise of the Warrants pursuant to the Warrant Certificate.

                                INDEMNIFICATION

         Section 7.1. General. (a) The Company (the "Indemnifying Party")
agrees and covenants to hold harmless and indemnify the Purchaser and each of
its Affiliates, and their respective managed accounts, shareholders, employees,
directors, officers, principals, equity holders, controlling Persons, advisors
and agents (each of the foregoing Persons being an "Indemnified Person"), from
and against any losses, claims, damages, liabilities and expenses (including
reasonable attorneys' fees and expenses of investigation) incurred by such
Indemnified Person (collectively, "Indemnifiable Costs and Expenses") in
connection with (i) any actual or threatened third-party action, suit,
proceeding or investigation arising out of or based in any manner upon the
Purchaser's negotiation, execution or performance of its obligations hereunder
or under the Registration Rights Agreement, the Warrant Certificate or the
Shareholders Agreement or its ownership of the Preferred Shares, the Warrants
or Common Shares, (ii) arising out of or based upon any breach by the
Indemnifying Party of any its representations, warranties or covenants
contained herein, in the Registration Rights Agreement, the Warrant Certificate
or the Shareholders Agreement or in any agreement, instrument or document
delivered by the Company hereunder or thereunder or (iii) enforcing the rights
of an Indemnified Person under this Agreement or under the Registration Rights
Agreement, the Warrant Certificate or the Shareholders Agreement.

         (b) The Indemnifying Party further agrees promptly upon demand by each
Indemnified Person to reimburse each Indemnified Person for any Indemnifiable
Costs and Expenses as they are incurred by it; provided that if the
Indemnifying Party reimburses an Indemnified Person hereunder for any expenses
incurred in connection with a lawsuit, claim, inquiry or other proceeding or
investigation for which indemnification is sought, such Indemnified Person
agrees to refund such reimbursement of expenses to the extent it is finally
judicially determined that the indemnity provided for in this Article VII is
not applicable to such Indemnified Person in accordance with the terms hereof
or otherwise. The Indemnifying Party further agrees that the indemnification,
contribution and reimbursement commitments set forth in this Article VII shall
apply whether or not an Indemnified Person is a formal party to any such
lawsuits, claims or other proceedings. The indemnity, contribution and expense

                                      -23-
<PAGE>

reimbursement obligation of the Indemnifying Party under this Article VII shall
be in addition to any liability it may otherwise have.

         (c) The obligations of the Indemnifying Party hereunder shall survive
the Closing and any repurchase, conversion, exchange or transfer of the
Preferred Shares or Warrants and the termination of this Agreement and shall
not be extinguished with respect to any Person because any other Person is not
entitled to indemnity or contribution hereunder.

         Section 7.2 Procedure. Promptly after receipt by an Indemnified Person
of notice from any third party of the commencement of any lawsuit, inquiry or
other proceeding or investigation thereof, such Indemnified Person will, if a
claim in respect thereof is to be made against the Indemnifying Party
hereunder, notify the Indemnifying Party in writing of the commencement
thereof; but the omission so to notify the Indemnifying Party will not relieve
the Indemnifying Party (x) from any liability which it may have to any
Indemnified Person hereunder unless the Indemnifying Party is actually
prejudiced thereby or (y) from any liability which it may have to any
Indemnified Person otherwise than pursuant to this Article VII. Each
Indemnified Person shall permit the Indemnifying Party to assume the defense of
such claim with counsel reasonably satisfactory to such Indemnified Person;
provided, however, that any Indemnified Person shall have the right to employ
separate counsel and to participate in the defense of such claim, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Person
unless (A) the Indemnifying Party has agreed to pay such fees or expenses, (B)
the Indemnifying Party shall have failed to assume the defense of such claim
and employ counsel reasonably satisfactory to such Indemnified Person in a
timely manner or (C) in the reasonable judgment of such Indemnified Person,
based upon advice of its counsel, a conflict of interest may exist between such
Indemnified Person and the Indemnifying Party with respect to such claims (in
which case, if such Indemnified Person notifies the Indemnifying Party in
writing that such Indemnified Person elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense of such claim on behalf of such Indemnified
Person). The Indemnifying Party will not be subject to any liability for any
settlement made without its consent (but such consent will not be unreasonably
withheld or delayed). No Indemnified Person will be required to consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Person of a release from all liability in respect of such claim or
litigation. An Indemnifying Party who is not entitled to, or elects not to,
assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all Indemnified Persons with respect to
such claim, as well as one local counsel in each relevant jurisdiction.

         Section 7.3. Contribution. (a) In order to provide for just and
equitable contribution in circumstances under which the indemnity provided for
in this Article VII is for any reason held to be unenforceable by the
Indemnified Person, the Indemnifying Party, in lieu of indemnifying such
Indemnified Person, shall have an obligation to contribute, and shall
contribute to the amount paid or payable by such Indemnified Person as a result
of such losses,

                                      -24-
<PAGE>

claims, damages, liabilities or expenses in such proportion as is appropriate
to reflect not only the relative benefits received by the Indemnifying Party
and the Indemnified Persons, but also to reflect the relative fault of the
Indemnifying Party and the Indemnified Persons in connection with the statement
or omissions which result in such losses, claims, damages, liabilities or
expenses, as well as any other relevant equitable considerations; provided,
however, that no Person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The relative fault of the Indemnifying Party and the
Indemnified Persons shall be determined, if applicable, by reference to, among
other things, whether the untrue statement of a material fact or the omission
to state a material fact has been made by, or relates to information supplied
by, the Indemnifying Party or Indemnified Persons and the Persons' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The amount paid or payable by a Person as a result
of the losses, claims, damages, liabilities and expenses referred to above
shall be deemed to include any reasonable legal or other fees or expenses
reasonably incurred by such Person in connection with investigation or
defending any such claim.

         (b) The Company and the Purchaser agree that it would not be just and
equitable if contribution pursuant to the immediately preceding paragraph were
determined by any method of allocation which does not take into account the
equitable considerations referred to in such paragraph.

         Section 7.4. Notification. Each party agrees to notify in writing
promptly the other party of the commencement of any litigation or proceeding
against it or any of its shareholders, officers, directors or agents in
connection with the issue of any the Preferred Shares, Warrants or Common
Shares.

         SECTION 3. DEMAND REGISTRATION.

         (a) Demand. Upon the written request of the Securityholder or a Holder
or Holders of a majority of the then outstanding Registrable Securities (on a
Common Stock equivalent basis) requesting that the Company effect the
registration under the Securities Act of Registrable Securities and specifying
the intended method or methods of disposition thereof (which may include a
continuous or delayed offering), the Company will use its best efforts to
effect, as expeditiously as possible, the registration under the Securities Act
of the Registrable Securities which the Company has been so requested to
register by the Securityholder or such Holder or Holders of Registrable
Securities; provided, however, that, except as provided below, the Company
shall not be obligated to (1) effect more than an aggregate of two (2) demand
registrations pursuant to this Section 3; or (2) effect a demand registration
unless either (I) the Registrable Securities for which the demand is made
constitute at least one-half of the then outstanding Registrable Securities (on
a Common Stock equivalent basis) or (II) the demand is made with respect to all
of the Registrable Securities then beneficially owned by the Securityholder or
the demanding Holder or Holders, provided such Registrable Securities
constitute at least 10% of the Registrable Securities initially issued by the
Company (on a Common Stock equivalent basis); and provided further that no
Holder (including the Securityholder) shall deliver a request for a demand
registration for a period of four (4) months following the last date on which a
Registration Statement filed in respect of the previous demand registration, if
any, was declared by the SEC to be effective. The number, percentage or kind of
shares in clause (2) above shall be appropriately adjusted for any stock
dividend, stock split, reverse stock split, combination, recapitalization,
reclassification, merger, consolidation, exchange, distribution or similar
transaction with respect to the shares of Common Stock. Notwithstanding the
foregoing, the Securityholder or a Holder or Holders of a majority of the then
outstanding Registrable Securities (on a Common Stock equivalent basis) shall
be entitled to unlimited additional demand registrations if such additional
demand registrations would be eligible for registration on Form S-3 (after the
Company qualifies for Form S-3, provided that in the case of any individual
such demand registration the aggregate gross proceeds from such S-3 demand
registration would exceed $500,000, if all registered shares thereunder were
sold); provided, however, that there shall be no more than two (2) such
registrations in any twelve (12) month period.

         Upon receipt of any request for registration pursuant to this Section
3 from the Securityholder or any Holder or Holders of Registrable Securities,
the Company shall promptly (but in any event within 20 days) give written
notice of such request to all other Holders. The Company shall include in the
requested registration all Registrable Securities requested to be included by
such of the other Holders who shall make such request by written notice to the
Company delivered within 30 days of their receipt of the Company's notice. If
the Company shall receive a request for inclusion in the registration of the
Registrable Securities of additional Holders, it shall promptly so inform in
writing the Person or Persons who made the initial request for registration.
Notwithstanding the foregoing, if the managing underwriter or underwriters of
the proposed public offering advises the Holder or Holders intending to
participate in such proposed public offering in writing that the total amount
or kind of securities which such Holder or Holders intends to include in such
proposed public offering is sufficiently large to materially adversely affect
the success of the proposed public offering, then the amount

                                     - 4 -
<PAGE>

or kind of securities to be offered for the accounts of all Holders whose
securities are included in such Registration Statement shall be reduced (on a
pro rata basis in the case of more than one such Holder) to the extent
necessary to reduce the total amount or kind of securities to be included in
such proposed public offering to the amount or kind recommended by such
managing underwriter or underwriters. The Company shall not register any
securities other than Registrable Securities in any demand registration
effected pursuant to this Section 3(a), except pursuant to Section 3(c) or with
the prior written consent of the Securityholder (if it is participating in such
offering) or, if the Securityholder is not participating in such offering, the
Holders of a majority of the Registrable Securities (on a Common Stock
equivalent basis) being sold pursuant to such offering.

         A Holder (including the Securityholder) or Holders requesting a
registration pursuant to this Section 3 may, at any time prior to the effective
date of the Registration Statement relating to such registration, revoke such
request by providing a written notice to the Company revoking such request. The
Company shall be required to pay all Registration Expenses with respect to the
first demand for registration to be revoked. If a Holder (including the
Securityholder) or Holders thereafter shall revoke any demand for registration,
such Holder (including the Securityholder) or Holders, at their option, shall
either pay all out-of-pocket Registration Expenses with respect to such revoked
demand or count such revoked demand as one of the demands for registration to
which Holders are entitled pursuant to this Section 3.

         (b) Effectiveness of Registration Statement. The Company agrees to use
its best efforts to (i) cause the Registration Statement relating to any demand
registration pursuant to this Section 3 to become effective as expeditiously as
possible; (ii) thereafter keep such Registration Statement effective
continuously for the period specified in the next succeeding paragraph and to
permit the sale of such Registrable Securities in accordance with the intended
method or methods of distribution thereof; and (iii) prevent the happening of
any event of the kinds described in clauses (4), (5) and (6) of Section
5(a)(ii).

         A demand registration requested pursuant to this Section 3 will not be
deemed to have been effected unless the Registration Statement relating thereto
has become effective under the Securities Act and remained continuously
effective (except as otherwise permitted under this Agreement) for a period
ending on the earlier of (i) the date that is nine (9) months after the
effective date of such Registration Statement (subject to extension as provided
in the final paragraph of Section 5(a), Section 6(a) and Section 6(b)) and (ii)
the date on which all Registrable Securities covered by such Registration
Statement have been sold and the distribution contemplated thereby has been
completed; provided, however, that if, after such Registration Statement has
become effective, the offering of the Registrable Securities pursuant to such
registration is interfered with by any stop order, injunction or similar order
of the SEC or other governmental agency or court (other than by reason of any
untrue statement of a material fact or any omission of a material fact required
to be stated in the Registration Statement or necessary to make the statements
therein not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information or affidavit furnished in
writing by a Holder to the Company specifically for inclusion therein), such
registration will be deemed not to have been effected.

                                     - 5 -
<PAGE>

         (c) Inclusion of Securities of Other Approved Holders. The Company and
any Other Approved Holder may include its securities in any demand registration
effected pursuant to this Section 3 that is not a Shelf Registration; provided,
however, that if the managing underwriter or underwriters of the proposed
public offering advises the Holder or Holders intending to participate in such
proposed public offering in writing that the total amount or kind of securities
which such Holders, the Company and such Other Approved Holders intend to
include in such proposed public offering is sufficiently large to materially
adversely affect the success of the proposed public offering requested by such
Holder or Holders, then the amount or kind of securities to be offered for the
accounts of the Other Approved Holders shall be reduced pro rata among such
Other Approved Holders to the extent necessary to reduce the total amount or
kind of securities to be included in such proposed public offering to the
amount or kind recommended by such managing underwriter or underwriters and, if
such reduction results in no securities being offered for the accounts of the
Other Approved Holders in such proposed public offering, then the amount or
kind of securities to be offered for the account of the Company shall be
reduced to the extent necessary to reduce the total amount or kind of
securities to be included in such proposed public offering to the amount or
kind recommended by such managing underwriter or underwriters.

         SECTION 4. PIGGYBACK REGISTRATION. If the Company at any time proposes
to file a registration statement with respect to any class of equity
securities, whether for its own account (other than in connection with the
Registration Statement contemplated by Section 3 or a registration statement on
Form S-4 or S-8 (or any successor or substantially similar form), or the
registration of (A) an employee stock option, stock purchase or compensation
plan or of securities issued or issuable pursuant to any such plan or (B) a
dividend reinvestment plan) or for the account of an Other Approved Holder (a
"Requesting Securityholder"), then the Company shall in each case give written
notice of such proposed filing to all Holders of Registrable Securities at
least 20 days before the anticipated filing date of any such registration
statement by the Company, and such notice shall offer to all Holders the
opportunity to have any or all of the Registrable Securities held by such
Holders included in such registration statement. Each Holder of Registrable
Securities desiring to have its Registrable Securities registered under this
Section 4 shall so advise the Company in writing within 15 days after the date
of receipt of such notice (which request shall set forth the amount of
Registrable Securities for which registration is requested), and the Company
shall include in such Registration Statement all such Registrable Securities so
requested to be included therein on the same terms and conditions as the
securities being registered by the Company. Any Holder's request for such
inclusion may be withdrawn, in whole or in part, at any time prior to the
effective date of such Registration Statement. Notwithstanding the foregoing,
if the managing underwriter or underwriters of any such proposed public
offering advises the Company in writing that the total amount or kind of
securities which the Holders of Registrable Securities, the Company and the
Other Approved Holders intend to be included in such proposed public offering
is sufficiently large to materially adversely affect the success of such
proposed public offering, then the amount or kind of securities to be offered
for the accounts of Holders of Registrable Securities and the Other Approved
Holders shall be reduced pro rata to the extent necessary to reduce the total
amount or kind of securities to be included in such proposed public offering to
the amount or kind recommended by such managing underwriter or underwriters
before the securities offered by the Company or any Requesting Securityholder
are so reduced.

         SECTION 5. REGISTRATION PROCEDURES.

         (a) General. In connection with the Company's registration obligations
pursuant to Sections 3 and 4 hereof, the Company will, as expeditiously as
practicable:

             (i) prepare and file with the SEC a new Registration Statement or
     such amendments and post-effective amendments to an existing Registration
     Statement as may be necessary to keep such Registration Statement
     effective for the time periods set forth in Section 3(b), provided that no
     Registration Statement shall be required to remain in effect after all
     Registrable Securities covered by such Registration Statement have been
     sold and distributed as contemplated by such Registration Statement, and
     provided, further, that as soon as practicable, but in no event later than
     three (3) Business Days before filing such Registration Statement, any
     related Prospectus or any amendment or supplement thereto, other than any
     amendment or supplement made solely as a result of incorporation by
     reference of documents filed with the SEC subsequent to the filing of such
     Registration Statement, the Company shall furnish to the Holders of the
     Registrable Securities covered by such Registration Statement and the
     underwriters, if any, copies of all such documents proposed to be filed,
     which documents shall be subject to the review of such Holders and
     underwriters; the Company shall not file any Registration Statement or
     amendment thereto or any Prospectus or any supplement thereto (other than
     any amendment or supplement made solely as a result of incorporation by
     reference of documents filed with the SEC subsequent to the filing of such
     Registration Statement) to which the managing underwriters of the
     applicable offering, if any, or the Securityholder (if it is participating
     in such offering) or the Holders of a majority of the Registrable
     Securities (on a Common Stock equivalent basis) covered by such
     Registration Statement shall have reasonably objected in writing within
     three (3) Business Days after receipt of such documents to the effect that
     such Registration Statement or amendment thereto or Prospectus or
     supplement thereto does not comply in all material respects with the
     requirements of the Securities Act (provided that the foregoing shall not
     limit the right of any Holder whose Registrable Securities are covered by
     a Registration Statement to reasonably object, within two (2) Business
     Days after receipt of such documents, to any particular information that
     is to be contained in such Registration Statement, amendment, Prospectus
     or supplement that relates specifically to such Holder, including any
     information describing the manner in which such Holder acquired such
     Registrable Securities and the intended method or methods of distribution
     of such Registrable Securities), and if the Company is unable to file any
     such document due to the objections of such underwriters, the
     Securityholder or such Holders, the Company shall use its best efforts to
     cooperate with such underwriters, the Securityholder and Holders to
     prepare, as soon as practicable, a document that is responsive in all
     material respects to the reasonable objections of such underwriters, the
     Securityholder and Holders; cause the Prospectus to be supplemented by any
     required Prospectus supplement, and as so supplemented to be filed
     pursuant to Rule 424; and comply with the provisions of the Securities Act
     applicable to the Company with respect to the disposition of all
     securities covered by such Registration Statement during the applicable
     period in accordance with the intended method or methods of distribution
     by the sellers thereof set forth in such Registration Statement,
     Prospectus or supplement to the Prospectus (it being understood

                                     - 7 -
<PAGE>

     that the Company shall not be deemed to have used its best efforts to keep
     a Registration Statement effective during the applicable period if any
     action is taken by the Company that would result in Holders of the
     Registrable Securities covered thereby not being able to sell such
     Registrable Securities during that period unless such action is required
     under applicable law or is contemplated under the last paragraph of
     Section 5(a), Section 6(a) or Section 6(b));

             (ii) notify the selling Holders of Registrable Securities and the
     managing underwriters, if any, promptly (providing confirmation in
     writing) (1) when a new Registration Statement, Prospectus or any
     Prospectus supplement or post-effective amendment has been filed, and,
     with respect to any new Registration Statement or post-effective
     amendment, when it has become effective, (2) of any request by the SEC for
     amendments or supplements to any Registration Statement or Prospectus or
     for additional information, (3) of the issuance by the SEC of any comments
     with respect to any filing, (4) of any stop order suspending the
     effectiveness of any Registration Statement or the initiation of any
     proceedings for that purpose, (5) in the case of an Underwritten Offering,
     if at any time the representations and warranties of the Company
     contemplated by paragraph (xi) below cease to be true and correct as of
     any time they are required to be true and correct, (6) of any suspension
     of the qualification or registration (or exemption therefrom) of the
     Registrable Securities for sale in any jurisdiction or the initiation or
     threatening of any proceeding for such purpose and (7) of the happening of
     any event which makes any statement of a material fact made in any
     Registration Statement, Prospectus or any document incorporated therein by
     reference untrue or which requires the making of any changes in any
     Registration Statement, Prospectus or any document incorporated therein by
     reference so that it will not contain any untrue statement of a material
     fact or omit to state any material fact required to be stated therein or
     necessary to make the statements therein (in the case of any Prospectus or
     supplement, in the light of the circumstances under which they were made)
     not misleading; and make every reasonable effort to obtain as soon as
     possible the withdrawal of any order or other action suspending the
     effectiveness of any Registration Statement or suspending the
     qualification or registration (or exemption therefrom) of the Registrable
     Securities for sale in any jurisdiction;

             (iii) if reasonably requested by the managing underwriter or
     underwriters or a Holder of Registrable Securities being sold in
     connection with an Underwritten Offering, promptly incorporate in a
     Prospectus supplement or post-effective amendment such information as the
     managing underwriters, the Securityholder (if it is participating in such
     offering) and the Holders of a majority of the Registrable Securities (on
     a Common Stock equivalent basis) being sold in such Underwritten Offering
     reasonably agree should be included therein relating to the sale of the
     Registrable Securities, including information with respect to the
     aggregate number of shares of Registrable Securities being sold to such
     underwriters, the purchase price being paid therefor by such underwriters
     and with respect to any other terms of the Underwritten Offering of the
     Registrable Securities to be sold in such offering; and promptly make all
     required filings of such Prospectus supplement or post-effective
     amendment;

                                     - 8 -
<PAGE>

             (iv) promptly after the filing of any document which is to be
     incorporated by reference into a Registration Statement or Prospectus,
     provide copies of such document to the selling Holders of the Registrable
     Securities covered thereby and the underwriters, if any;

             (v) promptly after the filing of such documents with the SEC,
     furnish to each selling Holder of Registrable Securities and each managing
     underwriter, if any, without charge, at least one manually signed or
     "edgarized" copy (but not to exceed five manually signed copies of any
     document to all selling Holders and underwriters in the aggregate), and as
     many conformed copies as may reasonably be requested, of the then
     effective Registration Statement and any post-effective amendments
     thereto, including financial statements and schedules, all documents
     incorporated therein by reference and all exhibits (including those
     previously furnished or incorporated by reference);

             (vi) deliver to each selling Holder of Registrable Securities and
     the underwriters, if any, without charge, as many copies of the then
     effective Prospectus (including each prospectus subject to completion) and
     any amendments or supplements thereto as such Persons may reasonably
     request; subject to the last paragraph of this Section 5(a), the Company
     consents to the use of any such Prospectus or any amendment or supplement
     thereto by the Holders and the underwriters, if any, in connection with
     the offering and sale of the Registrable Securities covered by any such
     Prospectus or any amendment or supplement thereto;

             (vii) register or qualify (or obtain exemption therefrom) or
     cooperate with the selling Holders of Registrable Securities, the
     underwriters, if any, and their respective counsel in connection with the
     registration or qualification (or exemption therefrom) of such Registrable
     Securities for the offer and sale under the securities or blue sky laws of
     such jurisdictions as any selling Holder of Registrable Securities or
     underwriter, if any, reasonably requests in writing; use its best efforts
     to keep each such registration or qualification (or exemption therefrom)
     effective during the period during which such registration statement is
     required to be kept effective pursuant to this Agreement; and do any and
     all other acts or things reasonably necessary or advisable to enable the
     disposition in such jurisdictions of the Registrable Securities covered by
     the then effective Registration Statement; provided, however, that the
     Company will not be required to qualify to do business in any jurisdiction
     where it would not otherwise be required to qualify, but for this
     paragraph (vii);

             (viii) cooperate with the selling Holders of Registrable
     Securities and the managing underwriters, if any, to facilitate the timely
     preparation and delivery of certificates representing Registrable
     Securities to be sold and not bearing any restrictive legends; and enable
     such Registrable Securities to be in such denominations and registered in

     incorporated therein by reference or file any other required document so
     that, as thereafter delivered to the purchasers of the Registrable
     Securities being sold thereunder, the Prospectus will not contain an
     untrue statement of a material fact or omit to state any material fact

     circumstances in which they were made, not misleading; if any event
     described in clause (2) of paragraph (ii) above occurs, use its best
     efforts to cooperate with the SEC to prepare, as soon as practicable, any

             (x) cause all Registrable Securities covered by the Registration

     requested by the Securityholder (if it is participating in such offering)
     or the Holders of a majority of the Registrable Securities (on a Common
     Stock equivalent basis) covered by such Registration Statement or the

     including, if necessary, a listing application and indemnification

     other matters as may be reasonably requested by such Holders and
     underwriters); (3) obtain "cold comfort" letters and updates thereof from
     the independent certified public accountants of the Company addressed to

     "cold comfort" letters from the independent certified public accountants
     of the Company at the time of effectiveness of such Registration Statement

     (on a Common Stock equivalent basis) covered by such Registration
     Statement, updates thereof of customary frequency, in each case addressed
     to each Holder of Registrable Securities participating in such offering
     and covering matters that are no more extensive in scope than would be

     secondary underwritten offerings by issuers with similar market
     capitalization and reporting and financial histories; and (3) deliver a
     certificate of a senior executive officer of the Company at the time of

     basis) covered by such Registration Statement, updates thereof of
     customary frequency, such certificates to cover matters no more extensive

     of any 12-month period (or 120 days, if such period is a fiscal year)
     commencing at the end of any fiscal quarter in which the Registrable
     Securities are sold to underwriters in a firm commitment or best efforts
     underwritten offering, or, if not sold to underwriters in such an
     offering, beginning with the first month of the Company's first fiscal
     quarter commencing after the effective date of such Registration
     Statement, which earnings statements shall cover such 12-month periods;

             (xv) cooperate and assist in any filings required to be made with
     the National Association of Securities Dealers, Inc. and in the
     performance of any customary or required due diligence investigation;

<PAGE>

             (xvi) make available for inspection by the Holders of the
     Registrable Securities covered by such Registration Statement, any
     underwriter participating in any disposition pursuant to such
     registration, and any attorney, accountant or other representative
     retained by such sellers or underwriter, all financial and other records,
     pertinent corporate documents and properties of the Company and cause the
     Company's officers, directors and employees to supply all information
     reasonably requested by, and to cooperate fully with, any such
     representative, underwriter, attorney or accountant in connection with
     such registration;

             (xvii) subject to the proviso in paragraph (vii) above, cause the
     Registrable Securities covered by the Registration Statement to be
     registered with or approved by such other governmental agencies or
     authorities as may be reasonably necessary to enable the seller or sellers
     thereof or the underwriters, if any, to consummate the disposition of such
     Registrable Securities; and

             (xviii) use its best efforts to take all action necessary or
     advisable to effect such registration in the manner contemplated by this
     Agreement.

         The Company may require each seller of Registrable Securities as to
which any registration is being effected to furnish to the Company such
information regarding such seller and the distribution of such securities as
the Company may from time to time reasonably request in writing.

         Each Holder of Registrable Securities agrees by acquisition of such
Registrable Securities that, upon receipt of any notice from the Company of the
happening of any event of the kind described in Section 5(a)(ii) hereof, such
Holder will forthwith discontinue disposition of Registrable Securities (but,
in the case of an event described in Section 5(a)(ii)(6), in the affected
jurisdiction or jurisdictions only) pursuant to the then current Prospectus
until (1) such Holder is advised in writing by the Company that a new
Registration Statement covering the offer of Registrable Securities has become
effective under the Securities Act or (2) such Holder receives copies of a
supplemented or amended Prospectus contemplated by this Section 5(a), or until
such Holder is advised in writing by the Company that the use of the Prospectus
may be resumed. If the Company shall have given any such notice during a period
when a demand registration is in effect, the Company shall extend the period
during which such registration statement shall be maintained effective pursuant
to this Agreement by the number of days during which any such disposition of
Registrable Securities is discontinued pursuant to this paragraph. The Company
shall use its best efforts to limit the duration of any discontinuance with
respect to the disposition of Registrable Securities pursuant to this
paragraph.

         (b) Additional Procedures for Shelf Registration. If the Holders
become entitled, pursuant to an event described in clause (ii) of the
definition of Registrable Securities, to receive any securities in respect of
Registrable Securities that were already included in a Shelf Registration
Statement, subsequent to the date such Shelf Registration Statement is declared
effective, and the Company is unable under the securities laws to add such
securities to the then-effective Shelf Registration Statement, the Company, as
promptly as practicable, shall file, in accordance with the procedures more
particularly set forth in Section 5(a), an additional Shelf

                                     - 12 -
<PAGE>

Registration Statement with respect to any such new Registrable Securities. The
Company shall use its best efforts to have any such additional Registration
Statement declared effective as promptly as practicable after such filing and
to keep such additional Shelf Registration Statement continuously effective
during the period specified in Section 3(b). A request to file an additional
Shelf Registration Statement pursuant to this paragraph shall not constitute a
demand under Section 3(a).

         SECTION 6. HOLDBACK AGREEMENTS.

         (a) Hold-Back Election. Subject to Section 6(c), in the case of the
registration of any underwritten primary offering initiated by the Company
(other than any registration by the Company on Form S-4 or Form S-8 (or any
successor or substantially similar form), or the registration of (A) an
employee stock option, stock purchase or compensation plan or of securities
issued or issuable pursuant to any such plan or (B) a dividend reinvestment
plan) or any underwritten secondary offering initiated at the request of an
Other Approved Holder, each Holder agrees, if and to the extent requested in
writing by the managing underwriter or underwriters administering such offering
as promptly as reasonably practicable prior to the commencement of the 10-day
period referred to below (a "Hold-Back Election"), not to effect any public
sale or distribution of securities of the Company except as part of such
underwritten registration, during the period beginning 10 days prior to the
effective date of the applicable registration statement relating to such
underwritten offering and ending on the earlier of (i) 90 days after such
effective date and (ii) the date such sale or distribution is permitted by such
managing underwriter or underwriters. In the event such managing underwriter or
underwriters shall exercise a Hold-Back Election during a period when a
Registration Statement filed pursuant to Section 3 is in effect, the time
period specified in Section 3(b) during which such Registration Statement is
required to be kept effective shall be extended by the number of days during
which the Holders are prohibited by such underwriter or underwriters from
publicly selling or distributing their securities. Notwithstanding the
foregoing provisions of this Section 6(a), no Holder shall be obligated to
refrain from making any public sale or distribution of securities of the
Company in the case of any underwritten secondary offering initiated at the
request of any Person who has not agreed in writing to expressly recognize and
give effect to the Holders' rights under this Section 6(a), and to be subject
to provisions that are at least as favorable to the Holders as the provisions
contained in this Section 6(a) are to such holder.

         (b) Material Development Election. Subject to Section 6(c), the
Company shall be entitled, for a period of time not to exceed 90 consecutive
days, to postpone the filing of any Registration Statement otherwise required
to be prepared and filed by it pursuant to Section 3 and/or to request that the
Holders refrain from effecting any public sales or distributions of their
Registrable Securities if the board of directors of the Company in good faith
determines in its reasonable business judgment that such registration and/or
such public sales or distributions would interfere in any material respect with
any financing (other than an underwritten secondary offering of any securities
of the Company), acquisition, corporate reorganization or other transaction or
development involving the Company or any subsidiary of the Company that in the
reasonable good faith business judgment of such board is a transaction or
development that is or would be material to the Company (a "Material
Development Election"). The board of directors of the Company shall, as
promptly as practicable, give the Holders written notice of

                                     - 13 -
<PAGE>

any such Material Development Election. In the event of a determination by the
board of directors to postpone the filing of a Registration Statement required
to be filed under Section 3 hereof, the Company shall be required to file such
Registration Statement as soon as practicable after the board of directors of
the Company shall determine, in its reasonable business judgment, that the
filing of such Registration Statement and the offering thereunder shall not
interfere with the aforesaid material transaction or development, but in any
event no later than the end of such 90-day period. In addition, if the board of
directors of the Company has requested that the Holders refrain from making
public sales or distributions of their Registrable Securities, such board
shall, as promptly as practicable following its determination that the Holders
may recommence such public sales and distributions, notify such Holders in
writing of such determination (but in any event no later than the end of such
90-day period). In the event the Company shall exercise a Material Development
Election during a period when a Registration Statement filed pursuant to
Section 3 is in effect, the time period specified in Section 3(b) during which
such Registration Statement is required to be kept effective shall be extended
by the number of days during which the Holders are prohibited by the Company
from publicly selling or distributing their securities.

         (c) Hold-Back Limitation. In no event shall the restrictions under
Section 6(a) or Section 6(b), pursuant to one or more Hold-Back Elections or
Material Development Elections, remain in effect for more than 90 days in the
aggregate in any calendar year.

         (d) Company Hold-Back. In the case of each underwritten offering of
Registrable Securities pursuant to Section 3, including under any Shelf
Registration Statement, the Company agrees, if and to the extent requested in
writing by the managing underwriter or underwriters administering such offering
as promptly as reasonably practicable prior to the commencement of the 10-day
period referred to below, not to effect any public sale or distribution (other
than sales pursuant to the same Registration Statement, as permitted under this
Agreement, or any registration by the Company on Form S-4 or S-8 (or any
successor or substantially similar form) or the registration of (A) an employee
stock option, stock purchase or compensation plan or of securities issued or
issuable pursuant to any such plan or (B) a dividend reinvestment plan) of any
securities of the Company during the period beginning 10 days prior to the
effective date of the applicable registration statement relating to such
underwritten offering of Registrable Securities and ending on the earlier of
(i) 90 days after such effective date and (ii) the date such sale or
distribution is permitted by such managing underwriter or underwriters. Any
agreement entered into after the date of this Agreement pursuant to which the
Company issues or agrees to issue any privately placed securities similar to
any issue of the Registrable Securities shall contain a provision under which
holders of such securities agree not to effect any public sale or distribution
of any such securities during the period described in the next preceding
sentence.

         SECTION 7. REGISTRATION EXPENSES. All expenses incident to the
Company's performance of or compliance with this Agreement, including all
registration and filing fees, fees and expenses of compliance with securities
or blue sky laws (including reasonable fees and disbursements of counsel in
connection with blue sky qualifications or registrations (or the obtaining of
exemptions therefrom) of the Registrable Securities), printing expenses
(including expenses of printing Prospectuses), messenger and delivery expenses,
internal expenses

                                     - 14 -
<PAGE>

(including all salaries and expenses of its officers and employees performing
legal or accounting duties), fees and disbursements of its counsel and its
independent certified public accountants (including the expenses of any special
audit or "comfort" letters required by or incident to such performance or
compliance), securities acts liability insurance (if the Company elects to
obtain such insurance), fees and expenses of any special experts retained by
the Company in connection with any registration hereunder, fees and expenses of
other Persons retained by the Company, fees and expenses of one counsel for the
Holders, selected by the Securityholder (if it is participating in such
offering) or, if the Securityholder is not participating in such offering, by
the Holders of a majority of the Registrable Securities (on a Common Stock
equivalent basis) being sold pursuant to such registration, incurred in
connection with each registration hereunder, and reasonable out-of-pocket
expenses incurred by the Holders (except as set forth in the proviso hereafter)
(all such expenses being referred to as "Registration Expenses"), shall be
borne by the Company, whether or not any registration statement becomes
effective (subject, however, to the provisions of Section 3(a)); provided that
Registration Expenses shall not include any underwriting discounts, commissions
or fees attributable to the sale of the Registrable Securities.

         SECTION 8. INDEMNIFICATION; CONTRIBUTION.

         (a) Indemnification by the Company. The Company shall indemnify and
hold harmless, to the full extent permitted by law, but without duplication,
each Holder of Registrable Securities, its officers, directors, employees,
partners, principals, equity holders, managed or advised accounts, advisors,
representatives and agents, and each Person who controls such Holder or such
other Persons (within the meaning of the Securities Act) and any investment
advisor thereof or agent therefor, against all losses, claims, damages,
liabilities and expenses (including reasonable costs of investigation and
reasonable legal fees and expenses) arising out of or based upon any untrue or
alleged untrue statement of a material fact in, or any omission or alleged
omission of a material fact required to be stated in, any Registration
Statement or any Prospectus, or necessary to make the statements therein (in
the case of a Prospectus, in light of the circumstances under which they were
made) not misleading, except in each case insofar, but only insofar, as the
same arises out of or is based upon an untrue statement or alleged untrue
statement of a material fact or an omission or alleged omission to state a
material fact in such Registration Statement or Prospectus, as the case may be,
made or omitted, as the case may be, in reliance upon and in conformity with
written information furnished to the Company by such Holder expressly for use
therein. The Company shall also indemnify underwriters of the Registrable
Securities, selling brokers, dealer managers and similar securities industries
professionals participating in the distribution, and their officers, directors,
employees, partners, principals, equity holders, advisors, representatives and
agents, and each Person who controls such underwriters or other Persons (within
the meaning of the Securities Act), to the same extent as provided above with
respect to the indemnification of the Holders of Registrable Securities and
other specified Persons. This indemnity is in addition to any liability that
the Company may otherwise have.

         (b) Indemnification by Holders of Registrable Securities. In
connection with any Registration Statement in which a Holder of Registrable
Securities is participating, each such Holder shall furnish to the Company in
writing such information and affidavits with respect to such Holder as the
Company reasonably requests for use in connection with such Registration

                                     - 15 -
<PAGE>

Statement or any Prospectus, and shall indemnify and hold harmless, to the full
extent permitted by law, but without duplication, the Company, its officers,
directors, shareholders, employees, advisors, representatives and agents, and
each Person who controls the Company or such other Persons (within the meaning
of the Securities Act) and any investment advisor thereof or agent therefor,
against any losses, claims, damages, liabilities and expenses (including
reasonable costs of investigation and reasonable legal fees and expenses)
arising out of or based upon any untrue or alleged untrue statement of a
material fact in, or any omission or alleged omission of a material fact
required to be stated in, the Registration Statement or any Prospectus, or
necessary to make the statements therein (in the case of a Prospectus, in light
of the circumstances under which they were made) not misleading, in each case
to the extent, but only to the extent, that the same arises out of or is based
upon an untrue statement or alleged untrue statement of a material fact or an
omission or alleged omission to state a material fact in such Registration
Statement or Prospectus, as the case may be, made or omitted, as the case may
be, in reliance upon and in conformity with written information furnished to
the Company by such Holder expressly for use therein. The Company shall be
entitled to receive indemnities from underwriters, selling brokers, dealer
managers and similar securities industries professionals participating in the
distribution, to the same extent as provided above with respect to information
so furnished in writing by such Persons specifically for inclusion in any
Prospectus or Registration Statement. Notwithstanding any other provision
hereof to the contrary, in no event shall the liability of any selling Holder
of Registrable Securities hereunder be greater in amount than the dollar amount
of the net proceeds actually received by such Holder upon the sale of the
Registrable Securities giving rise to such indemnification obligation.

         (c) Conduct of Indemnification Proceedings. Any Person entitled to
indemnification under this Section 8 will (i) give prompt written notice to the
indemnifying party of any claim with respect to which it seeks indemnification
and (ii) permit such indemnifying party to assume the defense of such claim
with counsel reasonably satisfactory to the indemnified party; provided,
however, that any Person entitled to indemnification hereunder shall have the
right to employ separate counsel and to participate in the defense of such
claim, but the fees and expenses of such counsel shall be at the expense of
such indemnified Person unless (A) the indemnifying party has agreed to pay
such fees or expenses, (B) the indemnifying party shall have failed to assume
the defense of such claim and employ counsel reasonably satisfactory to the
indemnified party in a timely manner or (C) in the reasonable judgment of any
such Person, based upon advice of its counsel, a conflict of interest may exist
between such Person and the indemnifying party with respect to such claims (in
which case, if the Person notifies the indemnifying party in writing that such
Person elects to employ separate counsel at the expense of the indemnifying
party, the indemnifying party shall not have the right to assume the defense of
such claim on behalf of such Person). The indemnifying party will not be
subject to any liability for any settlement made without its consent (but such
consent will not be unreasonably withheld or delayed). No indemnified party
will be required to consent to entry of any judgment or enter into any
settlement which does not include as an unconditional term thereof the giving
by the claimant or plaintiff to such indemnified party of a release from all
liability in respect of such claim or litigation. An indemnifying party who is
not entitled to, or elects not to, assume the defense of a claim will not be
obligated to pay the fees and expenses of more than one counsel for all parties
indemnified by such indemnifying party with respect to such claim, as well as
one local counsel in each relevant jurisdiction.

                                     - 16 -
<PAGE>

         (d) Contribution. If for any reason the indemnification provided for
in Section 8(a) or Section 8(b) is unavailable to an indemnified party, then
the indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by the indemnified party as a result
of such loss, claim, damage, liability or expense in such proportion as is
appropriate to reflect not only the relative benefits received by the
indemnifying party and the indemnified party, but also the relative fault of
the indemnifying party and the indemnified party in connection with the actions
that resulted in such loss, claim, damage, liability or expense, as well as any
other relevant equitable considerations, provided that no indemnifying Holder
shall be required to contribute an amount greater than the dollar amount of the
net proceeds actually received by such indemnifying Holder with respect to the
sale of the Registrable Securities giving rise to such contribution obligation.
The relative fault of such indemnifying party and indemnified party shall be
determined by reference to, among other things, whether any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission to state a material fact, has been made by, or relates to
information supplied by, such indemnifying party or indemnified party, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such action. The amount paid or payable by a party as a
result of the losses, claims, damages, liabilities and expenses referred to
above shall be deemed to include, subject to the limitations set forth herein,
any legal or other fees or expenses reasonably incurred by such party in
connection with any investigation or proceeding. The parties hereto agree that
it would not be just and equitable if contribution pursuant to this Section
8(d) were determined by pro rata allocation or by any other method of
allocation that does not take account of the equitable considerations referred
to in this paragraph. No Person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentations.

         SECTION 9. RULES 144 AND 144A. The Company shall use its best efforts
to make publicly available and available to the Holders, pursuant to Rule 144,
such information as is necessary to enable the Holders to make sales of
Registrable Securities pursuant to that Rule. The Company shall use its best
efforts to file timely with the SEC all documents and reports required of the
Company under the Exchange Act. The Company shall furnish to any Holder, upon
request, a written statement executed on behalf of the Company as to compliance
with the current public information requirements of Rule 144. In addition, the
Company will provide to any Holder of a Registrable Security, or any potential
purchaser of a Registrable Security, upon any such Person's reasonable request,
the information required by paragraph (d)(4) of Rule 144A.

         SECTION 10. PARTICIPATION IN UNDERWRITTEN REGISTRATIONS.

         (a) If any of the Registrable Securities covered by a demand
registration hereunder are to be sold in an Underwritten Offering, the
investment banker or investment bankers and manager or managers that will
administer the offering will be selected by the Securityholder (if it is
participating in such offering) or, if such Securityholder is not so
participating in such offering, the Holders of a majority of the Registrable
Securities (on a Common Stock equivalent basis) included in such offering;
provided that such investment bankers and managers must be reasonably
satisfactory to the Company, acting in good faith.

                                     - 17 -
<PAGE>

         (b) No Person may participate in any Underwritten Offering hereunder
unless such Person (i) agrees to sell such Person's Registrable Securities on
the basis provided in any underwriting arrangements approved by the Persons
entitled hereunder to approve such arrangements and (ii) completes and executes
all questionnaires, powers of attorney, indemnities, underwriting agreements
and other documents required under the terms of such underwriting arrangements.
Nothing in this Section 10 shall be construed to create any additional rights
regarding the registration of Registrable Securities in any Person otherwise
than as set forth herein.

         SECTION 11. NO INCONSISTENT AGREEMENTS. The Company (i) except as set
forth on Schedule 11 attached hereto, has not previously entered into any
agreement or understanding that is still in effect on the date hereof pursuant
to which it has granted registration or similar rights to any Person who holds
any of its securities and (ii) shall not enter into any agreement or
understanding (x) with respect to registration or similar rights on any of its
securities with any Person other than an Other Approved Holder or (y) which is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof.

         SECTION 12. AMENDMENTS AND WAIVERS. The provisions of this Agreement,
including the provisions of this Section 12, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of the
Securityholder (if the Securityholder then holds any Registrable Securities)
and the Holders of a majority of the Registrable Securities (on a Common Stock
equivalent basis) then outstanding. Whenever the consent or approval of Holders
of a specified number of Registrable Securities is required hereunder,
Registrable Securities held by the Company or any of its Affiliates (other than
Holders of Registrable Securities if such subsequent Holders are deemed to be
Affiliates solely by reason of their holdings of such Registrable Securities)
shall not be counted in determining whether such consent or approval was given

designate one director to the Board of Directors of the Company. The director
to be designated pursuant to this paragraph (b) may be removed with or without

                                  ARTICLE III

                    AGREEMENTS RELATING TO THE CAPITAL STOCK
                        OF THE COMPANY AND OTHER MATTERS

         3.1 TRANSFER OF CAPITAL STOCK. (a) For the period beginning on the
Effective Date and ending on the date that is two years thereafter (the
"Restricted Period"), the Existing Shareholders severally agree with the
Company, the Investor and with each other Shareholder that they will not,
directly or indirectly, Transfer any Capital Stock of the Company (or any
interest therein), now or hereafter at any time owned by them, except that each
Existing Shareholder may Transfer, upon written notice to the Company, the
Investor and each other Shareholder, in accordance with applicable law: (i) any
Common Stock of the Company pursuant to an Involuntary Transfer; (ii) any
Common Stock of the Company for estate planning purposes to such Existing
Shareholder's spouse, parents, siblings, children, stepchildren or
grandchildren or to a trust which is for the benefit of such Existing
Shareholder or such Existing Shareholder's spouse, parents, siblings, children,
stepchildren or grandchildren; (iii) during the period from (and including) the
Effective Date through (but excluding) the date that is one year thereafter
(the "Initial Period"), any Common Stock which does not exceed five percent
(5%) of all of the Common Stock held by such Existing Shareholder on the
Effective Date; and (iv) during the period from (and including) the last day of
the Initial Period through (and including) the last day of the Restricted
Period, any Common Stock which does not exceed fifteen percent (15%) of all of
the Common Stock held by such Existing Shareholder on the Effective Date;
provided, however, that, in connection with any Transfer permitted under this
Section 3.1(a), prior to such Transfer, such Existing Shareholder shall comply
with Section 3.1(b) hereof.

         (b) Any Transfer of Capital Stock of the Company by any Existing
Shareholder during the Restricted Period or at any time thereafter to a Related
Transferee shall not relieve the transferor of its obligations hereunder and
shall only be valid if the Person to whom such Capital Stock is Transferred (a
"Transferee"), prior to the Transfer, agrees in writing to be bound by the
terms of this Agreement as and to the same extent that the transferor

                                     - 6 -
<PAGE>

was bound by this Agreement immediately prior to such Transfer. Any such
Transferee that agrees to be bound by the terms of this Agreement as provided
in this paragraph (b) shall be deemed, upon execution and delivery of such
agreement, to be a Shareholder hereunder. Each such Transferee shall be
entitled to all of the rights under this Agreement to which the transferor was
entitled immediately prior to such Transfer. Any purported Transfer without
obtaining this agreement by the Transferee shall be deemed void and of no
further effect and shall be governed by the provisions of paragraph (c) below.
The provisions of this paragraph (b) shall not apply in connection with a
Public Transfer by an Existing Shareholder.

         (c) In the event a Transfer of any Capital Stock of the Company has
taken place or remains in place in violation of the provisions of this Article
III, such Transfer shall be void and of no effect, and no dividend of any kind
whatsoever nor any distribution pursuant to liquidation or otherwise shall be
paid by the Company or the related Shareholder to the Transferee in respect of
such Capital Stock (all such dividends and distributions being deemed waived),
and any voting rights of such Capital Stock on any matter whatsoever shall
remain vested in the transferor.

         (d) The provisions of this Section 3.1 shall be in addition to, and
shall not in any way limit the application of, any other provision of this
Agreement.

         3.2 TAG-ALONG RIGHTS. (a) If, at any time, any Existing Shareholder
and/or a Related Transferee or Related Transferees of such Existing Shareholder
(a "Section 3.2 Transferor") desires to Transfer any of its Common Stock in an
amount in excess of fifteen percent (15%) of all of the Common Stock held by
such Existing Shareholder on the Effective Date in one transaction or a series
of transactions to any Person or Persons (a "Section 3.2 Transferee"), except
pursuant to an Exempt Transfer or a Public Transfer, prior to any such
Transfer, such Section 3.2 Transferor shall promptly (and in any event at least
20 business days prior to the closing date thereof), provide each Investor
Holder (each, a "Prospective Participating Shareholder") with written notice of
the proposed Transfer (the "Transfer Notice") containing the following:

         (i) the name and address of the proposed Section 3.2 Transferee;

         (ii) the number of shares of Common Stock to be Transferred by such
    Section 3.2 Transferor; and

         (iii) the purchase price and other terms and conditions of payment and
    the closing date for the proposed Transfer (including, when available, a
    copy of any purchase agreement related thereto).

         (b) If any of such Prospective Participating Shareholders (each, a
"Participating Shareholder") wishes to participate in such Transfer, each such
Participating Shareholder may notify the Section 3.2 Transferor by written
notice (the "Tag-Along Notice") on or before the expiration of 15 business days
following receipt of the Transfer Notice that such Participating Shareholder
desires to Transfer to the proposed Section 3.2 Transferee a part of its shares
of Capital Stock of the Company (as determined pursuant to the following
sentence)

                                     - 7 -
<PAGE>

on the same terms and conditions set forth in the Transfer Notice. The
Tag-Along Notice shall specify the number of shares of such Capital Stock such
Participating Shareholder desires to Transfer (the "Tag-Along Amount"); for
purposes of making any determination or calculation pursuant to this Section
3.2, but for such purposes only, as of any date of determination or
calculation, all of the Capital Stock of the Company held by an Investor Holder
shall be deemed to have been fully converted, exercised or exchanged, to the
extent applicable, as of such date of determination or calculation. The maximum
number of shares of such Capital Stock that each such Participating Shareholder
separately shall be entitled to Transfer hereunder shall be determined by
multiplying the number of shares of such Capital Stock held by such
Participating Shareholder at the time of the Transfer Notice by a fraction, the
numerator of which is the number of shares of Common Stock proposed to be
Transferred to the Section 3.2 Transferee by the Section 3.2 Transferor and the
denominator of which is the number of shares of Common Stock then owned by the
Section 3.2 Transferor. If no Prospective Participating Shareholder provides
the Section 3.2 Transferor with a Tag-Along Notice within the period specified
above, the Section 3.2 Transferor shall be free to sell all or a portion of
such Common Stock to the Section 3.2 Transferee in the amount and on the same
terms and conditions set forth in the Transfer Notice, subject to paragraph (h)
below. If there is any Participating Shareholder(s), the Section 3.2 Transferor
may not effect such Transfer unless the Section 3.2 Transferee shall have
purchased the Tag-Along Amount or the Reduced Tag-Along Amount (as defined
below) from each such Participating Shareholder on the same terms and
conditions set forth in the Transfer Notice.

         (c) If the sum (the "Aggregate Shares Offered") of (i) the number of
shares of Common Stock proposed to be Transferred to the Section 3.2 Transferee
by the Section 3.2 Transferor and (ii) the aggregate Tag-Along Amounts for all
Participating Shareholders exceeds the number of shares of Common Stock that
such Section 3.2 Transferee is willing to purchase, then each such
Participating Shareholder shall be obligated to Transfer a number of shares of
Common Stock or its equivalent (the "Reduced Tag-Along Amount") equal to the
product of the number of shares of Common Stock which the Section 3.2
Transferee is willing to purchase and a fraction, the numerator of which is the
Tag-Along Amount with respect to such Person and the denominator of which is
the Aggregate Shares Offered, and the Section 3.2 Transferor shall be obligated
to Transfer a number of shares of Common Stock equal to the number of shares of
Common Stock which the Section 3.2 Transferee is willing to purchase minus the
Reduced Tag-Along Amount or Reduced Tag-Along Amounts for all Participating
Shareholders.

         (d) Any indemnity provided by a Participating Shareholder to the
Section 3.2 Transferee in a purchase agreement relating to such Transfer will
only relate to the shares of Capital Stock Transferred by it. Any indemnity
provided to the Section 3.2 Transferee by the Section 3.2 Transferor will only
relate to the shares of Common Stock Transferred by it.

         (e) The Section 3.2 Transferor and the Participating Shareholders
whose shares of Capital Stock are Transferred pursuant to this Section 3.2
shall be required to bear their pro rata share, based on the number of shares
of Capital Stock included in such Transfer, of the expenses of the transaction
including, without limitation, legal, accounting and investment banking fees
and expenses.

         (f) The Company shall, upon request by any Participating Shareholder,
issue to such Participating Shareholder one or more stock certificates
registered in the names and in the denominations (aggregating in a number equal
to the original denomination) requested by such Participating Shareholder, to
facilitate any partial sale of shares of any Capital Stock pursuant to this
Section 3.2.

         (g) To the extent that any prospective Section 3.2 Transferee is
unwilling or otherwise refuses to purchase Capital Stock from any Participating
Shareholder, the Section 3.2 Transferor shall not Transfer to such prospective
Section 3.2 Transferee any Common Stock, unless and until, simultaneously with
such Transfer, the Section 3.2 Transferor shall purchase such Capital Stock
from such Participating Shareholder on the same terms and conditions specified
in the Transfer Notice.

         (h) Subject to the rights of each Prospective Participating
Shareholder, if it has so elected, to participate in the Transfer of Common
Stock as provided in this Section 3.2, the Section 3.2 Transferor may, not
later than sixty (60) days following delivery to the Prospective Participating
Shareholders of the Transfer Notice, conclude a Transfer of Common Stock
covered by the Transfer Notice on the terms and conditions described in the
Transfer Notice. Any proposed Transfer on terms and conditions more favorable
to the Section 3.2 Transferee than those described in the Transfer Notice, as
well as any proposed Transfer of any Common Stock by the Section 3.2 Transferor
more than sixty (60) days following delivery to the Prospective Participating
Shareholders of the Transfer Notice, shall again be subject to the tag-along
rights of the Prospective Participating Shareholders and shall require
compliance by the prospective Section 3.2 Transferor with the procedures
described in this Section 3.2.

         (i) The exercise or non-exercise of the rights of any Prospective
Participating Shareholder under this Section 3.2 to participate in one or more
Transfers of Common Stock shall not adversely affect its right to participate
in subsequent Transfers of Common Stock pursuant to this Section 3.2.

         (j) The provisions of this Section 3.2 shall be subject in all
respects to the provisions of Section 3.1 hereof (except as otherwise set forth
herein).

         (k) This Section 3.2 shall remain in effect only so long as at least
250,000 shares of Series A Preferred Stock are outstanding (as adjusted for
stock splits, stock dividends, stock combinations, recapitalizations and like
occurrences).

         3.3 NO ISSUANCE OF CAPITAL STOCK. For the period beginning on the
Effective Date and ending nine (9) months thereafter, the Company shall not
issue or Transfer any of its Capital Stock without the Investor's prior written
consent, except for the issuance by the Company of shares of Common Stock (or,
in the case of clause (i) below, options to purchase Common Stock) in
connection with (i) the Stock Option Issuance (provided that during such nine
(9)-month period, such issuances shall not exceed options to purchase up to
225,000 shares of Common Stock and the issuance of Common Stock upon the
exercise of such options and provided, further, that no such options or shares
of Common Stock may be issued by the Company prior to January 1, 1997), (ii)
the conversion of the Series A Preferred Stock or the

                                     - 9 -

exercise of the Warrants or (iii) the exercise of warrants or options that are
outstanding as of the Effective Date and which are specified in Section 3.2 of
the Purchase Agreement.

         3.4 PARTICIPATION RIGHT ON NEW SECURITIES. During the Restricted
Period, the Company hereby grants to each of the Investor Holders
(collectively, the "Eligible Holders") the right of first refusal to purchase a
pro rata share of New Securities (as defined below) that the Company may, from
time to time, propose to sell and issue (the "Participation Right"). Each
Eligible Holder's pro rata share, for purposes of this Participation Right, is
the ratio of (X) the number of shares of Common Stock then owned by such
Eligible Holder to (Y) the total number of shares of Common Stock of the
Company outstanding immediately prior to the issuance of the New Securities,
assuming, in each case but for purposes of this Section 3.4 only, full
conversion of all shares of then outstanding Series A Preferred Stock and full
exercise of all then outstanding Warrants and other rights, options and
warrants to purchase or acquire Common Stock. This Participation Right shall be
subject to the following provisions:

             (a) "New Securities" shall mean any offering by the Company of any
Capital Stock of the Company, whether now authorized or not; provided, however,
that "New Securities" does not include (i) Common Stock issued pursuant to the
Stock Option Issuance; (ii) Common Stock issuable upon conversion of the Series
A Preferred Stock or upon exercise of the Warrants; (iii) Capital Stock issued
pursuant to the acquisition of another corporation by the Company by merger,
purchase of substantially all of the assets or other reorganization, whereby
the Company owns more than 50% of the voting power of such corporation; and
(iv) Common Stock issuable upon the exercise of warrants or options that are
outstanding as of the Effective Date and which are specified in Section 3.2 of
the Purchase Agreement.

             (b) In the event that the Company proposes to undertake an
issuance of New Securities, it shall give each Eligible Holder written notice
of its intention, describing the type of New Securities, the price and the
general terms and conditions upon which the Company proposes to issue the same.
Each Eligible Holder shall have twenty (20) business days from the date of
receipt of any such notice to agree to purchase its pro rata share of such New
Securities for the price and upon the general terms and conditions specified in
the notice by giving written notice to the Company and stating therein the
quantity of New Securities to be purchased.

             (c) In the event that the Eligible Holders fail to exercise in
full the Participation Right within said twenty (20) business day period, the
Company shall have sixty (60) days thereafter to sell the New Securities
respecting which the Eligible Holders' Participation Rights were not exercised
at a price and upon terms and conditions no more favorable to the purchasers
thereof than specified in the Company's notice. In the event the Company has
not sold the New Securities within said sixty (60) day period, the Company
shall not thereafter issue or sell any New Securities without first offering
such securities to the Eligible Holders in the manner provided above.

             (d) This Section 3.4 shall not limit in any respect the
obligations of the Company under Section 3.3.

                                     - 10 -

             (e) This Section 3.4 shall remain in effect only so long as at
least 250,000 shares of Series A Preferred Stock are outstanding (as adjusted
for stock splits, stock dividends, stock combinations, recapitalizations and
like occurrences).

         3.5 LEGENDS ON STOCK. Each Capital Stock certificate of the Company
held by an Existing Shareholder or any Transferee of an Existing Shareholder
shall bear the following legend on the face thereof:

         "THIS CERTIFICATE IS ISSUED SUBJECT TO THE PROVISIONS OF A
    SHAREHOLDERS AGREEMENT DATED AS OF DECEMBER 20, 1996, AND NEITHER THIS
    CERTIFICATE NOR THE SHARES REPRESENTED BY IT ARE ASSIGNABLE OR OTHERWISE
    TRANSFERABLE, EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SAID AGREEMENT, A
    COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY."

         "THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
    UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE
    SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED
    UNLESS REGISTERED UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAW OR
    UNLESS AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE."

Any certificate issued at any time in exchange or substitution for any
certificate bearing such legend (except a new certificate issued upon
completion of a public distribution under a registration statement of the
Capital Stock represented thereby) shall also bear such legend unless, in the
opinion of counsel for the holder of such Capital Stock (which counsel shall be
reasonably satisfactory to the Company), the Capital Stock represented thereby
is not, at such time, required by law to bear such legend. The Company agrees
that it will not Transfer on its books any certificate for its Capital Stock in
violation of the provisions of this Agreement.

who possesses Confidential Material to leave the employment of the Company or
such Subsidiary or (ii) any customer of the Company or any of its Subsidiaries
on behalf of any Person other than the Company or any such Subsidiary.

             (c) Each of the Existing Shareholders has had, and may be expected

employment and position with the Company, he has had access to and became
acquainted with Confidential Material. Except in the performance of his duties
as a director, officer or consultant of the Company, each Existing Shareholder
shall not, during the Term and at all times thereafter, directly or indirectly
for any reason whatsoever, disclose or use any such Confidential Material. All

Confidential Material to the extent, but only to the extent, (i) such
Confidential Material has been publicly disclosed (not due to a breach by such
Existing Shareholder of his obligations hereunder or by breach of any other
Person of a fiduciary or confidential obligation to the Company) or (ii) such
Existing Shareholder is required to disclose Confidential Material by or to any
court of competent jurisdiction or any governmental or quasi-governmental
agency, authority or instrumentality of competent jurisdiction, provided that
such Existing Shareholder shall, prior to any such disclosure, immediately
notify the Company of such requirement and provided, further, that the Company
shall have the right, at its expense, to object to such disclosures and to seek
confidential treatment of any Confidential Material to be so disclosed on such
terms as it shall determine.

             (d) In the case of each registration of any underwritten primary
offering initiated by the Company (other than any registration by the Company
on Form S-4 or Form S-8 (or any successor or substantially similar form), or
the registration of (A) an employee stock option, stock purchase or
compensation plan or of securities issued or issuable pursuant to any such plan
or (B) a dividend reinvestment plan) or any underwritten secondary offering
initiated at the request of any other Person (including, without limitation,
any demand registration initiated by the Investor or an Other Approved Holder
(as defined in the Registration Rights Agreement) under the Registration Rights
Agreement or otherwise, whether or not shares of Capital Stock of the Company
will be included by the Company in any such offering), each Existing
Shareholder severally agrees, if and to the extent requested in writing by the
managing underwriter or underwriters administering such offering as promptly as
reasonably practicable prior to the commencement of the ten (10)-day period
referred to below, not to effect any public Transfer of any Capital Stock of
the Company except as part of such underwritten registration, during the period
beginning ten (10) days prior to the effective date of the applicable

such Transfer is permitted by such managing underwriter or underwriters. The
provisions of this paragraph (b) shall (x) be in addition to, and shall not in
any way limit the application of, any other provision of this Agreement and (y)
remain in full force and effect for so long as the Registration Rights
Agreement is in effect, notwithstanding the earlier termination or expiration
of this Agreement.

         5.3 TERMINATION OF CURRENT SHAREHOLDERS' AGREEMENTS. Each of the
Existing Shareholders and the Company agree that all existing shareholders'

         7.6 GOVERNING LAW. This Agreement shall be deemed to be a contract
made under and shall be governed by and construed in accordance with the
internal laws of the State of New York without reference to the principles of
conflict of laws.

         7.7 CONSENT TO JURISDICTION AND SERVICE OF PROCESS. Any suit, action
or proceeding arising out of or relating to this Agreement, the Related
Documents or the transactions contemplated hereby or thereby may be instituted
in any Federal court situated in the State of New York or any state court of
the State of New York in each case, in the Borough of Manhattan, City of New
York, and each party agrees not to assert, by way of motion, as a defense or
otherwise, in any such suit, action or proceeding, any claim that it is not
subject personally to the jurisdiction of such court, that the suit, action or
proceeding is brought in an inconvenient forum, that the venue of the suit,
action or proceeding is improper or that this Agreement, the Related Documents
or the subject matter hereof or thereof may not be enforced in or by such
court. Each party further irrevocably submits to the jurisdiction of such court
in any such suit, action or proceeding. Any and all service of process and any
other notice in any such suit, action or proceeding shall be effective against
any party if given personally or by registered or certified mail, return
receipt requested, or by any other means of mail that requires a signed
receipt, postage fully prepaid, mailed to such party as herein provided.
Nothing herein contained shall be deemed to affect the right of any party to
serve process in any manner permitted by law or to commence legal proceedings
or otherwise proceed against any other party in any other jurisdiction.

         7.8 FURTHER ASSURANCES. Each of the parties hereto shall execute and
deliver such documents, instruments and agreements and take such further
actions as may be reasonably required or desirable to carry out the provisions
of this Agreement, the Related Documents and the transactions contemplated
hereby and thereby, and each of the parties hereto shall cooperate with each
other in connection with the foregoing.

         7.9 SPECIFIC PERFORMANCE. The parties acknowledge that irreparable
damage would occur to the Investor in the event that any of the provisions of
this Agreement or any of the Related Documents were not performed by the other
parties hereto in accordance with their specific terms or were otherwise
breached by such other parties and that money damages would not provide an
adequate remedy to the Investor. It is accordingly agreed that the Investor
shall be entitled to an injunction and other equitable remedies to prevent
breaches by the other parties hereto of this Agreement and the Related
Documents, and to enforce specifically the terms and provisions hereof or
thereof in any court of the United States or any state thereof having
jurisdiction, this being in addition to any other remedy to which the Investor
may be entitled at law or in equity.

         7.10 SEVERABILITY OF PROVISIONS. Any provision of this Agreement which
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction. If any provision in Section 5.2 hereof is held to be invalid or
unenforceable because of the scope or duration of or the area covered by such
provision, the parties hereto agree that the court making such determination
shall reduce the scope, duration and/or area of such provision (and

                                     - 22 -
<PAGE>

shall substitute appropriate provisions for any such invalid or unenforceable
provisions) in order to make such provision enforceable to the fullest extent
permitted by law and/or shall delete specific words and phrases, and such
modified provision shall then be enforceable and shall be enforced. The parties
hereto recognize that if, in any judicial proceeding, a court shall refuse to
enforce any of the separate covenants contained in Section 5.2 hereof, then
that invalid or unenforceable covenant contained in Section 5.2 hereof shall be
deemed eliminated from this Agreement to the extent necessary to permit the
remaining separate covenants hereof to be enforced. In the event that any court
determines that the time period or the area, or both, are unreasonable and that
any of the covenants in Section 5.2 hereof is to that extent invalid or
unenforceable, the parties hereto agree that such covenants will remain in full
force and effect, first, for the greatest time period, and second, in the
greatest geographical area that would not render them enforceable.

         7.11 HEADINGS. The Article and Section headings used or contained in
this Agreement are for convenience of reference only and shall not affect the
construction of this Agreement.

         7.12 COSTS AND EXPENSES. The respective parties hereto shall pay all
costs and expenses that each respectively incurs with respect to the
negotiation, execution and delivery of this Agreement and the Related
Documents.

         7.13 WAIVER OF JURY TRIAL. The parties hereto hereby irrevocably waive
all right to a trial by jury in any action, proceeding or counterclaim arising
out of or relating to this Agreement, the Related Documents or the transactions
contemplated hereby or thereby.

         7.14 PUBLICITY. The parties agree that no public release or
announcement concerning this Agreement or any of the Related Documents or the
transactions contemplated hereby or thereby shall be made without advance
review and approval by the Company and the Investor, except as otherwise
required by applicable law.

         7.15 NATURE OF AGREEMENTS. The covenants and agreements of the parties
in this Agreement are several and not joint covenants and agreements, unless
otherwise expressly specified herein.

provisions contained herein, or as may be required to comply with any law, or
with any rule or regulation made pursuant thereto, or with any rule or
regulation of any securities exchange (or any other quotation system operated
by a national securities association) on which the Warrants may be listed. Each
Warrant Certificate shall be manually executed on behalf of the Company by its
Chairman of the Board of Directors, Chief Executive Officer, President or one
of its Vice-Presidents under its corporate seal and attested by its Secretary
or an Assistant Secretary.

         Each Warrant Certificate may be signed on behalf of the Company by any
person who, at the actual date of the execution of such Warrant Certificate,
shall be the proper officer of the Company to sign such Warrant Certificate. If
any officer whose signature is on a Warrant Certificate no longer holds that
office after the date of issuance of the Warrant Certificate, such Warrant
Certificate shall be valid nevertheless.

         The Company shall maintain books for the registration and transfer of
Warrants. The Company will maintain an office where notices, presentations and
demands in respect of the Warrants may be made upon it and where books for
registration and transfer of the Warrant Certificates will be kept (the
"COMPANY OFFICE"). Such books shall show the names and addresses of the
respective registered holders of the Warrant Certificates, the number of
Warrants evidenced on the face of each of the Warrant Certificates, and the
date of each of the Warrant Certificates. Such books shall also show the names
and addresses of former registered holders of Warrant Certificates who may be
entitled to receive a payment under Section 2(c)(ii) hereof.

                                      -2-

         The Company Office shall be maintained at Alcohol Sensors
International, Ltd., 11 Oval Drive, Islandia, New York 11722, Attention: Joseph
M. Lively, until such time as the Company shall notify the registered holders
of the Warrants of any change of location of the Company Office (which shall
always be located within the 48 contiguous states of the United States of
America).

         As provided in Section 3 hereof, the Company shall transfer, from time
to time, any outstanding Warrants upon the books to be maintained by the
Company for such purpose upon surrender thereof for transfer properly endorsed
or accompanied by appropriate instructions for transfer. Warrants may be
exchanged at the option of the registered holder thereof, when surrendered at
the Company Office, for another Warrant or other Warrants of different
denominations, of like tenor and representing in the aggregate the right to
purchase a like number of shares of Common Stock.

         The Warrants evidenced by this Warrant Certificate may not be
transferred except in compliance with the provisions of the Securities Act of
1933, as amended (and any similar successor statute), together with the rules
and regulations promulgated thereunder (the "SECURITIES ACT"), or applicable
state securities laws and in accordance with the provisions of Section 14
hereof.

         SECTION 2. Exercise of Warrants; Purchase Price. (a) Subject to the
provisions of Section 6(d) hereof, the registered holder of this Warrant
Certificate, may exercise the Warrants evidenced hereby, in whole or in part,
at any time on or prior to the Final Expiration Date, upon surrender of this
Warrant Certificate, with the Form of Election to Purchase attached hereto duly
executed, to the Company at the Company Office, together with payment of the
Purchase Price for each share of Common Stock as to which such Warrants are
exercised.

         (b) The aggregate Purchase Price for the Warrants exercised shall be
payable (i) in cash, (ii) by certified or official bank or bank cashier's check
payable to the order of the Company, (iii) by delivery to the Company of shares
of Common Stock, which shares shall be deemed to have a value equal to the
Closing Price thereof (as such term is defined in Section 11 hereof), or
Warrants, which Warrants shall be deemed to have a value equal to the Closing
Price of the shares of Common Stock for which such Warrants are exercisable, or
(iv) any combination of the foregoing.

         (c) Upon receipt of a Warrant Certificate representing exercisable
Warrants, with the Form of Election to Purchase duly executed, accompanied by
payment of the aggregate Purchase Price for the shares of Common Stock to be
purchased and an amount equal to any applicable transfer tax required to be
paid by the registered holder of such Warrant Certificate in accordance with
Section 6 hereof, the Company shall thereupon promptly (i) requisition, from
any transfer agent of the Common Stock, certificates for the number of whole
shares of Common Stock to be purchased, and cause the same to be delivered to
or upon the order of the registered holder of such Warrant Certificate,
registered in such name or names as may be designated by such holder, (ii) when
appropriate, requisition the amount of cash to be paid in lieu of issuance of
fractional shares, or

                                      -3-
<PAGE>

requisition for sale by the Company the whole shares of Common Stock
representing such aggregate fractional shares, in accordance with Section 11
hereof, and deliver such cash, or the net proceeds of the sale of aggregated
fractional shares of Common Stock, to or upon the order of the registered
holder of such Warrant Certificate.

         (d) If the registered holder of any Warrant Certificate shall exercise
less than all the Warrants evidenced thereby, a new Warrant Certificate
evidencing Warrants equivalent to the Warrants remaining unexercised shall be
issued by the Company to the registered holder of such Warrant Certificate or
to his duly authorized assigns.

         SECTION 3. Transfer, Split Up, Combination and Exchange of Warrant
Certificates; Mutilated, Destroyed, Lost or Stolen Warrant Certificates.
Subject to the provisions of Section 14 hereof, at or prior to the Final
Expiration Date, any Warrant Certificate, with or without other Warrant
Certificates, may be transferred, split up, combined or exchanged for another
Warrant Certificate or Warrant Certificates, entitling the registered holder to
purchase a like number of shares of Common Stock as the Warrant Certificate or
Warrant Certificates surrendered then entitled such holder to purchase. Any
registered holder desiring to transfer, split up, combine or exchange any
Warrant Certificate shall make such request in writing delivered to the Company
and shall surrender the Warrant Certificate or Warrant Certificates to be
transferred, split up, combined or exchanged at the Company Office. Thereupon
the Company shall execute and deliver to the person or persons entitled thereto
a Warrant Certificate or Warrant Certificates, as the case may be, as so
requested. The Company may require payment of a sum sufficient to cover any tax
or governmental charge that may be imposed in connection with any transfer,
split-up, combination or exchange of Warrant Certificates.

         Upon receipt by the Company of an affidavit of the registered holder
as to the loss, theft, destruction or mutilation of a Warrant Certificate, such
indemnity as the Company may reasonably require and, in the case of mutilation,
upon surrender and cancellation of the mutilated Warrant Certificate, the
Company will execute and deliver a new Warrant Certificate of like tenor to the
registered holder in lieu of the Warrant Certificate so lost, stolen, destroyed
or mutilated. The Company acknowledges that a written indemnity by the
registered holder shall be satisfactory to it.

         SECTION 4. Subsequent Issue of Warrant Certificates. Subsequent to its
original issuance, no Warrant Certificate shall be issued in respect of this
Warrant Certificate except (a) Warrant Certificates issued upon any transfer,
combination, split-up or exchange of Warrants pursuant to Section 3 hereof, (b)
Warrant Certificates issued in replacement of mutilated, destroyed, lost or
stolen Warrant Certificates pursuant to Section 3 hereof, (c) Warrant
Certificates issued pursuant to Section 2(d) hereof upon the partial exercise
of any Warrant Certificate to evidence the unexercised portion of such Warrant
Certificate and (d) Warrant Certificates issued pursuant to Section 15 hereof.

         SECTION 5. Cancellation and Destruction of Warrant Certificates. All
Warrant Certificates surrendered to the Company for the purpose of exercise,
exchange, substitution, transfer, split-up or combination shall be cancelled by
it, and no Warrant

                                      -4-
<PAGE>

Certificates shall be issued in lieu thereof except as expressly permitted by
any of the provisions thereof. The Company shall cancel and retire any other
Warrant Certificates purchased or acquired by the Company otherwise than upon
the exercise thereof. The Company shall destroy such cancelled Warrant
Certificates.

         SECTION 6. Reservation and Availability of Shares of Common Stock,
etc.

         (a) The Company covenants and agrees that it will take all such action
as may be necessary to cause to be reserved and kept available at all times out
of its authorized and unissued shares of Common Stock or its authorized and
issued shares of Common Stock held in its treasury, the number of shares of
Common Stock that will be sufficient to permit the exercise in full of all
outstanding Warrants. The transfer agent for the Common Stock and every
subsequent transfer agent for any shares of the Company's capital stock
issuable upon the exercise of any Warrants will be irrevocably authorized and
directed at all times to reserve such number of authorized shares as shall be
required for such purpose. The Company will keep copies of the Warrant
Certificates and the Registration Rights Agreement dated as of even date
herewith, between the Company and American International Insurance Company (as
amended, supplemented or otherwise modified from time to time, the
"REGISTRATION RIGHTS AGREEMENT"), on file with each transfer agent. The Company
will furnish the transfer agent a copy of all notices of adjustments and
certificates related thereto, transmitted to each registered holder of a
Warrant Certificate pursuant to Section 9 hereof.

         (b) So long as the Common Stock issuable upon the exercise of Warrants
may be listed on any national securities exchange or eligible for trading on
NASDAQ (or any other quotation system operated by a national securities
association), the Company covenants and agrees that it shall take all such
action as may be necessary to cause all shares reserved for such issuance to be
listed as expeditiously as reasonably possible on such exchange or to be made
so eligible as expeditiously as possible upon official notice of issuance upon
such exercise.

         (c) The Company covenants and agrees that it will take all such action
as may be necessary to ensure that all shares of Common Stock delivered upon
exercise of Warrants shall, at the time of such issuance (subject to payment of
the Purchase Price), be duly and validly authorized and issued and fully paid
and nonassessable shares, free of preemptive rights and free from all taxes,
liens, charges, security interests or other encumbrances with respect to the
issuance thereof, and no personal liability shall attach to the ownership
thereof.

         (d) The Company covenants and agrees that it will pay when due and
payable any and all federal and state transfer taxes and charges which may be
payable in respect of the initial issuance or delivery of the Warrant
Certificates pursuant to Section 1 hereof or of the issuance and delivery of
any shares of Common Stock upon the exercise of Warrants, except as set forth
in the immediately following sentence. The Company shall not be required to pay
any tax which may be payable in respect of any transfer or delivery of Warrant
Certificates to a Person other than, or the issuance or delivery of
certificates for Common Stock in a name other than that of, or payment of cash
to a Person other than, the

                                      -5-
<PAGE>

registered holder of the Warrant Certificate evidencing Warrants surrendered
for exercise or to issue or deliver any certificates for shares of Common Stock
or pay any cash upon the exercise of any Warrants until any such tax shall have
been paid (any such tax being payable by the registered holder of such Warrant
Certificate at the time of surrender) or until it has been established to the
Company's reasonable satisfaction that no such tax is due. "PERSON" shall mean
any individual, corporation, partnership, limited liability company, trust,
incorporated or unincorporated association, joint venture, joint stock company
or other entity of any kind, including without limitation, any government or an
agency or political division thereof.

         (e) The Company will not, by amendment of its Certificate of
Incorporation or its other organizational documents or through any
consolidation, merger, reorganization, transfer of assets, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of the Warrants.

         (f) Subject, in the case of any registration under the Securities Act,
to the limitations set forth in Section 14 hereof, the Company covenants and
agrees that it will take all such action as may be necessary to obtain and keep
effective any and all permits, registrations, consents and approvals of
governmental agencies and authorities and to make all securities acts filings
and effect and maintain any registrations of securities under federal and state
laws (including, without limitation, the Securities Act and state "blue sky"
securities laws) which may become requisite in connection with the valid
issuance, sale, transfer or delivery of the Warrant Certificates, the exercise
of the Warrants and the valid issuance, sale, transfer and delivery of any
Common Stock or other securities issued or delivered upon exercise of, or
otherwise in connection with, the Warrants.

         SECTION 7. Record Date. Each person in whose name any certificate for
shares of Common Stock is issued upon the exercise of Warrants shall for all
purposes be deemed to have become the holder of record of the Common Stock
represented thereby on, and such certificate shall be dated, the close of
business on the date upon which the Warrant Certificate evidencing such
Warrants is duly surrendered and payment of the Purchase Price (and any
applicable transfer taxes) is made; provided, however, that if the date of such
surrender and payment is a date upon which the Common Stock transfer books of
the Company are closed, such person shall be deemed to have become the record
holder of such shares on, and such certificate shall be dated, the opening of
business on the next succeeding business day on which the Common Stock transfer
books of the Company are open.

         SECTION 8. Adjustment of Purchase Price, Number of Shares or Number of
Warrants. The Purchase Price, the number of shares of Common Stock covered by
each Warrant and the number of Warrants outstanding are subject to adjustment
from time to time as provided in this Section 8.

              (a) If the Company shall at any time, (i) pay a dividend on its
         outstanding Common Stock in shares of Common Stock or effect a
         distribution to holders of its outstanding Common Stock payable in
         shares of Common Stock, (ii) subdivide the outstanding Common Stock,
         (iii) combine the

                                      -6-
<PAGE>

         outstanding Common Stock into a smaller number of shares of Common
         Stock, or (iv) issue any securities of the Company in a
         reclassification of the Common Stock (including any such
         reclassification in connection with a consolidation or merger in which
         the Company is the continuing or surviving corporation), the number
         and kind of securities issuable in respect of each Warrant, commencing
         on the record date for such dividend or distribution or the effective
         date of such subdivision, combination or reclassification, shall be
         proportionately adjusted so that the registered holder of any Warrant
         exercised after such time shall be entitled to receive upon exercise
         of such Warrant the aggregate number and kind of securities which, if
         such Warrant had been exercised immediately prior to such date and at
         a time when the Common Stock transfer books of the Company were open,
         it would have owned upon such exercise and been entitled to receive by
         virtue of such dividend, distribution, subdivision, combination or
         reclassification. Such adjustments shall be made successively whenever
         any event listed above shall occur.

              (b) If the Company shall fix a record date for the making of a
         distribution to holders of Common Stock (including any such
         distribution made in connection with a consolidation or merger in
         which the Company is the continuing or surviving corporation other
         than a consolidation or merger in respect of which an adjustment is
         made pursuant to Section 10 hereof) of evidences of indebtedness or
         assets (including cash) or rights, options, warrants or other
         securities entitling them to subscribe for, purchase, convert to,
         exchange for or otherwise acquire Common Stock, the Purchase Price in
         effect after such record date shall be determined by multiplying the
         Purchase Price in effect immediately prior to such record date by a
         fraction, the numerator of which shall be the Purchase Price on such
         record date, less the fair market value (as determined in good faith
         by the Board of Directors of the Company) of the portion of the
         assets, evidences of indebtedness or such rights, options, warrants or
         other securities so to be distributed or paid applicable to one share
         of Common Stock and the denominator of which shall be such Purchase
         Price. No such distribution shall be made on treasury shares. Such
         adjustments shall be made successively whenever any such distribution
         is made and shall become effective immediately after the record date
         for the determination of stockholders entitled to receive such
         distribution.

              (c) If the Company shall at any time or from time to time after
         the date hereof issue (x) shares of Common Stock, (y) rights, options,
         warrants or other securities entitling the holder thereof to subscribe
         for, purchase, convert to, exchange for or otherwise acquire Common
         Stock or (z) rights, options, warrants or other securities entitling
         the holder thereof to subscribe for, purchase, convert to, exchange
         for or otherwise acquire such convertible or exchangeable securities
         (in each case other than Excluded Securities (as defined herein) and
         other than issuances that result in an adjustment under Section 8(a)
         or 8(b) hereof), without consideration or for a consideration per
         share of Common Stock less than the Purchase Price in

                                      -7-
<PAGE>

         effect immediately prior to the issuance of such Common Stock or such
         rights, options, warrants or other securities, the Purchase Price in
         effect immediately prior to each such issuance shall forthwith be
         adjusted to a price equal to the quotient obtained by dividing:

              (A) an amount equal to the sum of

                  (I) the total number of shares of Common Stock outstanding
         immediately prior to such issuance (including any shares of Common
         Stock deemed to have been issued pursuant to subsections (A) and (B)
         of Section 8(c)(2) (it being understood that the shares of Common
         Stock issuable upon exercise of the Warrants immediately prior to such
         issuance shall be deemed to be outstanding for all purposes of the
         computation required in this clause (A))) multiplied by the Purchase
         Price in effect immediately prior to such issuance, plus

                  (II) the consideration received by the Company upon such
         issuance, by

              (B) the total number of shares of Common Stock outstanding
         (including any shares of Common Stock deemed to have been issued
         pursuant to subdivisions (A) and (B) of Section 8(c)(2) (it being
         understood that the shares of Common Stock issuable upon exercise of
         the Warrants immediately prior to such issuance shall be deemed to be
         outstanding for all purposes of the computation required in this
         clause (B))) immediately after the issuance of such Common Stock.

         For the purposes of any adjustment of the Purchase Price pursuant to
         this Section 8(c), the following provisions shall be applicable:

              (1) In the case of the issuance of Common Stock for a
    consideration in whole or in part other than cash, the consideration other
    than cash shall be deemed to be the fair market value thereof as determined
    in good faith by the Board of Directors of the Company, irrespective of any
    accounting treatment.

              (2) In the case of (x) the issuance of rights, options or
    warrants entitling the holder thereof to subscribe for, purchase or
    otherwise acquire Common Stock, (y) securities convertible into or
    exchangeable for Common Stock or (z) rights, options, warrants or other
    securities convertible into or exchangeable for such convertible or
    exchangeable securities:

                  (A) the aggregate maximum number of shares of Common Stock
         deliverable upon exercise of such rights, options or warrants
         entitling the holder thereof to subscribe for, purchase or otherwise
         acquire Common Stock shall be deemed to have been issued at the time
         such rights, options or warrants were issued and for a consideration
         equal to the consideration

                                      -8-
<PAGE>

         (determined in the manner provided in subdivision (1) above), if any,
         received by the Company upon the issuance of such rights, options or
         warrants plus the minimum purchase price provided in such rights,
         options or warrants for the Common Stock covered thereby;

                  (B) the aggregate maximum number of shares of Common Stock
         deliverable upon conversion of or in exchange for any such convertible
         or exchangeable securities or upon the exercise of rights, options or
         warrants to subscribe for, purchase or otherwise acquire such
         convertible or exchangeable securities and subsequent conversion or
         exchange thereof shall be deemed to have been issued at the time such
         rights, options, warrants or securities were issued and for a
         consideration equal to the consideration received by the Company for
         any such rights, options, warrants and securities (excluding any cash
         received on account of accrued interest or accrued dividends), plus
         the consideration, if any, to be received by the Company upon the
         conversion or exchange of such securities or the exercise of any
         related rights, options or warrants (the consideration in each case to
         be determined in the manner provided in subdivision (1) above);

                  (C) on any change in the number of shares of Common Stock
         deliverable upon exercise of any such rights, options or warrants or
         conversions of or exchanges for such convertible or exchangeable
         securities or any change in the consideration to be received by the
         Company upon the exercise of any such rights, options or warrants or
         conversions of or exchanges for such convertible or exchangeable
         securities, other than a change resulting from the anti-dilution
         provisions thereof, the Purchase Price shall forthwith be readjusted
         to such Purchase Price as would have obtained had the adjustment made
         upon the issuance of such rights, options, warrants or securities not
         converted prior to such change been made upon the basis of such
         change; and

                  (D) on the expiration of any such rights, options or
         warrants, the termination of any such rights to convert or exchange or
         the expiration of any rights, options or warrants related to such
         convertible or exchangeable securities, the Purchase Price shall
         forthwith be readjusted to such Purchase Price as would have obtained
         had the adjustment made upon the issuance of such rights, options,
         warrants or securities or rights, options or warrants related to such
         securities been made upon the basis of the issuance of only the number
         of shares of Common Stock actually issued upon exercise of such
         rights, options or warrants, upon the conversion or exchange of such
         securities or upon the exercise of the rights, options or warrants
         related to such securities and subsequent conversion or exchange
         thereof.

         (4) "EXCLUDED SECURITIES"" means (A) shares of the Series A Cumulative
    Non-redeemable Convertible Preferred Stock issued on the date hereof and
    shares of Common Stock issued upon the conversion thereof; and (B) Common

                                      -9-
<PAGE>

    Stock issued (I) to employees or directors of, or consultants to, the
    Company, pursuant to any agreement, plan or arrangement approved by the
    Board of Directors of the Company, or options to purchase or rights to
    subscribe for such Common Stock, or securities by their terms convertible
    into or exchangeable for such Common Stock, or options to purchase or
    rights to subscribe for such convertible or exchangeable securities, in
    each case as approved by the Board of Directors of the Company, but only to
    the extent that the maximum aggregate number of shares of Common Stock so
    issued or issuable pursuant to all such agreements, plans and arrangements
    does not exceed (x) 300,000 shares of Common Stock in the aggregate in any
    fiscal year of the Company or (y) 600,000 shares of Common Stock in the
    aggregate (in each case subject to adjustment to reflect stock splits,
    stock dividends, stock combinations, recapitalizations and like
    occurrences) and (II) upon the exercise of the warrants and options
    exercisable for Common Stock outstanding on the date hereof as specified on
    Schedule A attached hereto.

              (d) If at any time, as a result of an adjustment made pursuant to
         Section 8(a) hereof, the registered holder of any Warrant thereafter
         exercised shall become entitled to receive any securities of the
         Company other than shares of Common Stock, thereafter the number of
         such other securities so receivable upon exercise of any Warrant shall
         be subject to adjustment from time to time in a manner and on terms as
         nearly equivalent as practicable to the provisions with respect to the
         shares of Common Stock contained in this Section 8 and the provisions
         of this Warrant Certificate with respect to the shares of Common Stock
         shall apply on like terms to any such other securities.

              (e) Upon each adjustment of the Purchase Price as a result of the
         calculations made in Section 8(b) or 8(c) hereof, each Warrant
         outstanding immediately prior to the making of such adjustment shall
         thereafter evidence the right to purchase, at the adjusted Purchase
         Price, that number of shares of Common Stock (calculated to the
         nearest hundredth) obtained by (i) multiplying (x) the number of
         shares covered by a Warrant immediately prior to this adjustment of
         the number of shares by (y) the Purchase Price in effect immediately
         prior to such adjustment of the Purchase Price and (ii) dividing the
         product so obtained by the Purchase Price in effect immediately after
         such adjustment of the Purchase Price.

              (f) Upon each adjustment of the number of shares of Common Stock
         for which the Warrants are exercisable as provided in Section 8(a)
         hereof, the Purchase Price payable upon exercise of a Warrant shall be
         adjusted by multiplying such Purchase Price immediately prior to such
         adjustment by a fraction (i) the numerator of which shall be the
         number of shares of Common Stock for which a Warrant was exercisable
         prior to such adjustment and (ii) the denominator of which shall be
         the number of shares of Common Stock for which a Warrant is
         exercisable immediately thereafter.

<PAGE>

              (g) Irrespective of any adjustment or change in the Purchase
         Price or the number or kind of securities issuable upon the exercise
         of each Warrant, the Warrant Certificates theretofore or thereafter
         issued may continue to express the Purchase Price per share and the
         number and kind of shares which were stated in the initial Warrant
         Certificate or any Warrant Certificate(s) subsequently issued in lieu
         thereof (but the actual kind and number of securities purchasable upon
         the exercise of Warrants represented by any Warrant Certificate and
         the Purchase Price thereof shall in all cases be as determined in
         accordance with the provisions contained therein).

              (h) Before taking any action that would cause an adjustment
         reducing the Purchase Price below the then par value, if any, of the
         shares of Common Stock issuable upon exercise of the Warrants, the
         Company shall take any corporate action which may, in the opinion of
         its counsel, be necessary in order that the Company may validly and
         legally issue fully paid and nonassessable shares of such Common Stock
         at such adjusted Purchase Price.

              (i) The Company may, at its option and in its sole discretion, at
         any time or from time to time during the term of the Warrants, reduce
         the then current Purchase Price to an amount deemed appropriate by the
         Board of Directors of the Company (but in no event shall the Purchase
         Price be less than the par value of a share of Common Stock);
         provided, however, that if the Company elects to so reduce the then
         current Purchase Price, (i) such reduction shall remain in effect for
         at least a 30-day period, after which time the Company may, at its
         option, reinstate the Purchase Price in effect prior to such reduction
         (subject to adjustment by virtue of or in connection with the
         provisions of Sections 8 and 10 hereof, and (ii) the Company shall
         deliver to the registered holders of Warrants an unqualified opinion
         of counsel prior to such reduction, to the effect that such reduction
         will not result in any federal or New York State or New York local
         taxable income (other than increased gains or reduced losses on the
         sale of shares of Common Stock) to such holders as a result of such
         reduction. Whenever the Purchase Price is so reduced, the Company
         shall give notice to the registered holders of Warrants of the
         reduction at least 15 days prior to the date on which the reduced
         Purchase Price takes effect stating the reduced Purchase Price and the
         period it will be in effect.

         SECTION 9. Certificate of Adjusted Purchase Price or Number of Shares.
Whenever an adjustment is made as provided in Section 8 hereof, the Company
shall forthwith file, at the office of the Company and any transfer agent
designated by the Company for the Warrants, a certificate of its chief
financial officer, showing in detail the facts requiring such adjustment and
the Purchase Price then in effect, and mail a copy of such certificate by
first-class certified mail, return receipt requested, postage prepaid, to each
registered holder of a Warrant Certificate in accordance with Section 16
hereof.

         SECTION 10. Consolidation, Merger or Sale of Assets, etc. (a) In case
the Company after the date hereof (i) shall consolidate with or merge into any
other Person and shall not be the continuing or surviving corporation of such
consolidation or merger, or (ii) shall permit any other Person to consolidate
with or merge into the Company and the Company shall be the continuing or
surviving Person but, in connection with such consolidation or merger, the
Common Stock shall be changed into or exchanged for stock or other securities
of any other Person or cash or any other property, or there shall be no such
change or exchange but the holders of Common Stock shall hold 50% or less of
the aggregate voting power of the continuing or surviving Person, or (iii)
shall transfer all or substantially all of its properties or assets to any
other Person, or (iv) shall effect a capital reorganization or reclassification
of Common Stock (other than a capital reorganization or reclassification for
which adjustment in the Purchase Price is provided for in Section 8 hereof),
then, and in the case of each such transaction, proper provision shall be made
so that, upon the basis and the terms and in the manner provided herein, the
registered holders of Warrants upon the exercise hereof at any time after the
consummation of such transaction, shall be entitled to receive (at the
aggregate Purchase Price in effect at the time of such consummation for all
Common Stock issuable upon such exercise immediately prior to such
consummation), in lieu of shares of the Common Stock issuable upon such
exercise prior to such consummation, the stock and other securities, cash and
property to which such holders would have been entitled upon such consummation
if such holder had exercised the rights represented by the Warrants immediately
prior thereto, subject to adjustments (subsequent to such corporate action) as
nearly equivalent as possible to the adjustments provided for in this Section
10 and in Section 8.

         (b) Notwithstanding anything contained herein to the contrary, the
Company will not effect any of the transactions described in subdivisions (i)
through (iv) of Section 10(a) unless, prior to the consummation thereof, each
Person (other than the Company) that may be required to deliver any stock,
securities, cash or property upon the exercise of Warrants as provided herein
shall assume, by written instrument delivered to, and reasonably satisfactory
to, the registered holders of the Warrants, (i) the obligations of the Company
under the Warrants (and if the Company shall survive the consummation of such
transaction, such assumption shall be in addition to, and shall not release the
Company from, any continuing obligations of the Company under the Warrants),
(ii) the obligations of the Company under the Registration Rights Agreement,
and (iii) the obligation to deliver to the registered holders of the Warrants
such shares of stock, securities, cash or property as, in accordance with the
provisions of this Section 10, such holders may be entitled to receive. The
Warrants shall thereafter continue in full force and effect and the terms
thereof (including, without limitation, all of the provisions of this Section
10) shall be applicable to the stock, securities, cash or property which such
Person may be required to deliver upon any exercise of the Warrants or the
exercise of any rights pursuant hereto.

         (c) If any event shall occur as to which the provisions of Sections 8
and 10(a)-(b) are not strictly applicable but as to which the failure to make
any adjustment would adversely affect the purchase rights represented by this
Warrant in accordance with the essential intent and principles of such sections
(which are to place the registered holders of Warrants in a position as nearly
equal as possible to the position such holders would have

                                      -12-
<PAGE>

occupied had such holders purchased shares of Common Stock on the date hereof),
then, in each such case, the Board of Directors of the Company, in its good
faith, shall cause the Company to make such adjustments, on a basis consistent
with the essential intent and principles established in Sections 8 and
10(a)-(b), necessary to preserve, without dilution, the purchase rights
represented by the Warrants.

         (d) The provisions of this Section 10 shall similarly apply to
successive mergers or consolidations or sales or other transfers or
transactions.

         SECTION 11. Fractional Shares. (a) The Company shall not be required
to issue fractions of shares of Common Stock upon exercise of the Warrants or
to distribute certificates which evidence fractional shares. Subject to Section
11(b) hereof, in lieu of such fractional shares of Common Stock, there shall be
paid to each registered holder of a Warrant Certificate with regard to which a
fractional share would otherwise be issuable at the time such Warrant
Certificate is exercised as herein provided an amount in cash equal to, at the
election of the Company, (i) the same fraction of the current market value of a
share of Common Stock or (ii) such holder's respective pro rata share of the
net proceeds of the sale by the Company of the aggregate fractional shares of
Common Stock to which such holder would otherwise have been entitled. If the
Company shall elect to pay the holders their pro rata share of the net proceeds
of the sale of the aggregate fractional shares of Common Stock, the Company
shall, within ten (10) Business Days following the date of the exercise of
Warrants with regard to which such fractional shares would otherwise be
issuable, aggregate and sell all fractional shares at then prevailing prices
and shall deliver the net proceeds of such sales pro rata to each of the
registered holders entitled thereto. For purposes of this Section 11(a), the
current market value of a share of Common Stock shall be the average Closing
Price (as determined pursuant to Section 11(c) hereof) for the ten (10) Trading
Days immediately preceding the date of such exercise.

         (b) If the Company is unable to pay any amounts of cash in respect of
fractional shares of Common Stock in accordance with Section 11(a) hereof by
reason of the provisions of the Company's then outstanding debt obligations or
otherwise, and insufficient shares of Common Stock are available to permit the
Company to aggregate and sell such fractional shares as provided therein, the
Company shall deliver to such holders an additional share of Common Stock in
lieu of such fractional shares.

         (c) For the purpose of any computation required in accordance with
this Section 11, the "CLOSING PRICE" with respect to the Common Stock on any
day (other than a day on which securities are generally not traded on the
applicable securities exchange or in the applicable securities market) shall
mean the average of the reported closing bid and asked prices on the Nasdaq
National Market or, if the Common Stock is not listed or admitted to trading on
the Nasdaq National Market, the last reported sales price regular way on the
New York Stock Exchange or the American Stock Exchange or, if the Common Stock
is not listed or admitted to trading on the Nasdaq National Market, the New
York Stock Exchange or the American Stock Exchange, the average of the closing
bid and asked prices in the over-the-counter market as furnished by any New
York Stock Exchange member firm selected from time to time by the Company for
that purpose. If the Security is not so listed, traded or

                                      -13-
<PAGE>

quoted, the Closing Price for any day shall mean the fair value of the security
as determined in good faith by the Board of Directors of the Company. The term
"TRADING DAY" shall mean a day on which the principal national securities
exchange on which the security is listed or admitted to trading is open for the
transaction of business or, if the security is not listed or admitted to
trading on any national securities exchange, a Business Day. The term "BUSINESS
DAY" shall mean any day other than a Saturday, a Sunday, or a day on which
banking institutions in the State of New York are authorized or obligated by
law or executive order to close.

         SECTION 12. Right of Action; Entitlement to Vote or Receive Dividends.

         (a) All rights of action in respect of the Warrants are vested in the
respective registered holders of the Warrant Certificates; and any registered
holder of any Warrant Certificate, without the consent of the registered holder
of any other Warrant Certificate, may, on its own behalf and for its own
benefit, enforce, and may institute and maintain any suit, action or proceeding
against the Company to enforce, or otherwise act in respect of, its right to
exercise the Warrants evidenced by such Warrant Certificate in the manner
provided in such Warrant Certificate.

         (b) Prior to the exercise of the Warrants evidenced thereby and the
date of the certificate representing the shares of Common Stock issuable upon
exercise of such Warrants pursuant to Section 7 hereof, the registered holder
of a Warrant Certificate, as such, shall not be entitled to any rights of a
stockholder of the Company with respect to, or be deemed for any purpose the
holder of, shares for which the Warrants shall be exercisable, including,
without limitation, the right to vote or to receive dividends, or other
distributions, and shall not be entitled to receive any notice of any
proceedings of the Company, except as specifically provided herein.

         SECTION 13. Agreement of Warrant Certificate Holders. Every registered
holder of a Warrant Certificate, by accepting the same, consents and agrees
with the Company and with every other registered holder of a Warrant
Certificate that (a) the Warrant Certificates are transferable only on the
registry books of the Company if surrendered at the Company Office, duly
endorsed or accompanied by a proper instrument of transfer, and (b) the Company
may deem and treat the Person in whose name the Warrant Certificate is
registered as the absolute owner thereof and of the Warrants evidenced thereby
(notwithstanding any notations of ownership or writing on the Warrant
Certificates) for all purposes whatsoever, and the Company shall not be
affected by any notice to the contrary.

         SECTION 14. Registration Rights Agreement; Legends; Restrictions on
Transfer.

         (a) The registered holders of the shares of Common Stock or other
securities issuable upon the exercise of the Warrants evidenced hereby (the
"WARRANT SHARES") shall have the rights with respect to the registration of
such Warrant Shares as set forth in the Registration Rights Agreement. The
Company shall keep on file at the Company

                                      -14-
<PAGE>

Office a copy of the Registration Rights Agreement, including any amendments
thereto, and shall furnish copies thereof, without charge, to any registered
holder upon request.

         (b) The registered holder of this Warrant Certificate, each transferee
hereof and any holder or transferee of any Warrant Shares, by acceptance
thereof, each agrees that (i) no public distribution of Warrant Shares will be
made in violation of the Securities Act and (ii) during such period as the
delivery of a prospectus with respect to the Warrant Shares may be required by
the Securities Act, no public distribution of Warrant Shares will be made in a
manner or on terms different from those set forth in, or without delivery of, a
prospectus then meeting the requirements of the Securities Act, and in
compliance with applicable state securities laws; provided that any holder or
transferee of any Warrant Shares may sell such Warrant Shares in one or more
transactions not requiring registration under the Securities Act.

         (c) Until such time as (i) the resale of the Warrants evidenced by the
Warrant Certificate have been registered under an effective registration
statement under the Securities Act, (ii) a restrictive legend is not required
in order to ensure compliance with the Securities Act or (iii) applicable state
securities laws or any restrictions on transfer have ceased or are permitted to
terminate under the Securities Act and applicable state securities law
(including, without limitation, pursuant to Rule 144 of the Securities Act),
this Warrant Certificate shall bear a legend in substantially the following
form by which the holder hereof shall be bound (and any transferee hereof shall
agree in writing to be bound):

         NEITHER THE WARRANTS REPRESENTED BY THIS WARRANT CERTIFICATE NOR ANY
         SECURITIES ISSUABLE UPON THE EXERCISE OF SUCH WARRANTS HAVE BEEN
         REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY OTHER
         SECURITIES LAWS, AND NEITHER SUCH WARRANTS NOR SUCH SECURITIES MAY BE
         SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF
         SUCH REGISTRATION UNDER SAID ACT AND LAWS OR AN EXEMPTION THEREFROM.

         (d) Until such time as (i) the resale of the Warrant Shares have been
registered under an effective registration statement under the Securities Act,
(ii) a restrictive legend is not required in order to ensure compliance with
the Securities Act or (iii) applicable state securities laws or any
restrictions on transfer have ceased or are permitted to terminate under the
Securities Act and applicable state securities laws, the certificate or
certificates evidencing the Warrant Shares shall bear a legend in substantially
the following form by which the holder thereof shall be bound (and any
transferee thereof shall agree in writing to be bound):

         THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
         UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY OTHER

                                      -15-
<PAGE>

         SECURITIES LAWS, AND SUCH SECURITIES MAY NOT BE SOLD, PLEDGED,
         HYPOTHECATED OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH
         REGISTRATION UNDER SAID ACT AND LAWS OR AN EXEMPTION THEREFROM.

         (e) Upon satisfaction of the conditions set forth in Section 14(c) or
14(d) hereof, as the case may be, the Company shall, upon the request of any
registered holder thereof, execute and deliver (without expense to such holder
or its designee) a Warrant Certificate(s) or certificate(s) evidencing Warrant
Shares, as the case may be, to the holder thereof or its designee, of like
tenor, not bearing the applicable legend otherwise required by this Section 14,
provided that, in connection with the conditions set forth in Sections
14(c)(ii) and (iii) and 14(d)(ii) and (iii), such holder shall deliver to the
Company an opinion of counsel for such holder, in form and substance reasonably
satisfactory to the Company, to the effect that such legend is no longer
required under applicable law.

         (f) With a view to making available to holders of the Warrant Shares
the benefits of certain rules and regulations of the Securities and Exchange
Commission (including without limitation Rules 144 and 144A under the
Securities Act) that may permit the sale of Warrants and Warrant Shares to the
public without registration, the Company agrees to take any and all such
actions as may be reasonably required of it to make available to such holders
such benefits, including without limitation, to: (i) make and keep public
information available, as those terms are understood and defined in Rule 144
under the Securities Act, and (ii) file with the Securities and Exchange
Commission in a timely manner all reports and other documents required of the
Company under the Securities Act and the Securities Exchange Act of 1934.

         SECTION 15. Issuance of New Warrant Certificates. Notwithstanding any
of the provisions contained in the Warrant Certificates to the contrary, the
Company may, at its option, issue new Warrant Certificates evidencing Warrants
in such form as may be approved by its Board of Directors to reflect any
adjustment or change in the Purchase Price per share and the number or kind or
class of shares of stock or other securities or property purchasable under the
Warrant Certificates made in accordance with the provisions thereof.

         SECTION 16. Notice of Proposed Actions. In the event (a) that the
Company shall propose to pay any dividend to the holders of its Common Stock or
to make any other distribution to the holders of its Common Stock, (b) that the
Company shall propose to offer to the holders of its Common Stock rights,
warrants or options to subscribe for or to purchase any additional shares of
Common Stock or shares of stock of any class or any other securities, rights or
options, (c) that the Company or any of its stockholders shall propose a public
offering of any shares of Common Stock or other securities for which the
Warrants shall be exercisable, (d) of any capital reorganization the Company,
or any recapitalization or reclassification of its Capital Stock or other
transaction described in Section 10 hereof, (e) of any consolidation, merger,
sale, transfer or other disposition of all or substantially all of the

involuntary liquidation, dissolution or winding-up of the Company, (g) of the
effectuation

                                      -16-
<PAGE>

by the Company of a transaction or series of related transactions in which 50%
or more of the voting power of the Company is disposed of, or (h) of any other
action that would require an adjustment in the Purchase Price or in the shares
of Common Stock or other securities or assets to which any registered holder of
Warrants is entitled pursuant to Section 8 or Section 10 hereof; then, in each
such case, the Company shall give to each registered holder of a Warrant
Certificate notice of such proposed action specifying (i) the record date for
the purpose of such dividend, distribution or right, and the amount and

case of a public offering, any additional information reasonably necessary to
permit the registered holder to determine whether to exercise this Warrant.
Such notice shall be given at least 20 days prior to the earliest date therein
specified.

         SECTION 17. Notices. Notices, demands or other communications given or

performance of the terms and provisions of this Warrant Certificate by the
holders of the Warrants.

law, any objection that it may now have or hereafter obtain to the

AND ASSIGNS) TO WAIVE THE RIGHT TO A TRIAL BY JURY IN ANY COURT AND IN ANY
ACTION OR PROCEEDING OF ANY TYPE IN WHICH THE COMPANY OR ANY OF ITS RESPECTIVE
SUCCESSORS OR ASSIGNS IS A PARTY, AS TO ALL MATTERS AND THINGS ARISING DIRECTLY

evidencing such warrants) being issued on the Initial Issue Date to the initial
holder of the Series A Preferred Stock.

         SECTION 3. Dividends; Other Distributions. (a) The holders of shares
of Series A Preferred Stock shall be entitled to receive cash dividends out of
funds legally available for payment of dividends. Dividends shall be payable in
cash at the rate of 9.0% of the Stated Value per share per annum and 9.0% per
annum (compounded semi-annually) on any accrued dividends on such shares,
whether or not declared, that remain unpaid beyond the next succeeding Dividend
Payment Date; provided, however, that the Corporation shall, at its option, be
entitled to issue additional shares of Series A Preferred Stock in lieu of cash
in respect of dividends payable on or prior to the first four Dividend Payment
Dates occurring after the Initial Issue Date.

         (b) Dividends on shares of Series A Preferred Stock shall accrue and
be cumulative from the date of issuance of such shares. Dividends shall be
payable semi-annually in arrears, when and as declared by the Board of
Directors of the Corporation, on June 30 and December 31 of each year (each, a
"Dividend Payment Date"), commencing on June 30, 1997. If any Dividend Payment
Date occurs on a day that is not a Business Day, any dividends otherwise
payable on such Dividend Payment Date shall be paid on the next Business Day.
Dividends shall be paid to the holders of record of the Series A Preferred
Stock as their names shall appear on the share register of the Corporation on
the Record Date for such dividend. Dividends payable in any Dividend Period
that is less than a full Dividend Period in length shall be computed on the
basis of a 180 day-period and actual days lapsed in such Dividend Period.
Dividends on account of arrears or any past Dividend Periods may be declared
and paid at any time to holders of record on the Record Date therefor.

         (c) So long as any shares of Series A Preferred Stock shall be
outstanding, the Corporation shall not declare, pay or set apart for payment on
any Junior Stock any dividends whatsoever, whether in cash, property or
otherwise (other than dividends payable in shares of the class or series upon
which such dividends are declared or paid, or payable in shares of Common Stock
with respect to Junior Stock other than Common Stock, together with cash in
lieu of fractional shares), nor shall the Corporation make any distribution on
any Junior Stock, nor shall any Junior Stock be purchased, redeemed or
otherwise acquired by the Corporation or any of its Subsidiaries, nor shall any
monies be paid or made available for a sinking fund for the purchase or
redemption of any Junior Stock, in each case unless (i) all dividends to which
the holders of shares of Series A Preferred Stock shall have been entitled for
all previous Dividend Periods shall have been paid in full and (ii) all such
dividends for the immediately preceding two Dividend Periods shall have been
paid exclusively in cash.

         (d) Without limiting any of the foregoing, in the event that full
dividends are not paid or made available to the holders of all outstanding
shares of Series A Preferred Stock and funds available for the payment of
dividends shall be insufficient to permit payment in full to holders of all
such stock of the full preferential amounts to which they are then entitled,
then the entire amount available for payment of dividends shall be distributed
ratably among all such holders of Series A Preferred Stock in proportion to the
full amount to which they would otherwise be respectively entitled.

<PAGE>

         SECTION 4. Rights on Liquidation, Dissolution or Winding-Up. In the
event of any voluntary or involuntary liquidation, dissolution or winding-up of
the Corporation, the sale of all or substantially all of the assets of the
Corporation, the merger or consolidation of the Company with or into any Person
in a transaction in which the Company is not the surviving entity or the
effectuation by the Corporation of a transaction or series of related
transactions in which 50% or more of the voting power of the Corporation is
disposed of, the holders of Series A Preferred Stock shall then be entitled to
receive immediately, prior and in preference to any distribution to the holders
of any class or series of capital stock of the Corporation, whether now
existing or hereafter created, the Liquidation Preference per share of Series A
Preferred Stock (subject to equitable adjustment to reflect stock splits, stock
dividends, stock combinations, recapitalization and like occurrences and
dividends and other distributions to holders of Common Stock of indebtedness or
assets of the Corporation). If the assets of the Corporation available for
distribution to the holders of Series A Preferred Stock shall be insufficient
to permit the payment in full of the Liquidation Preference per share, the
assets of the Corporation shall be ratably distributed among the holders of the
Series A Preferred Stock in proportion to the full amounts to which they would
otherwise be respectively entitled if all such amounts thereon were paid in
full.

         SECTION 5. Optional Conversion. (a) Each holder of any shares of
Series A Preferred Stock shall have the right, at such holder's option, at any
time or from time to time, to convert any of such shares into such whole number
of fully paid and non-assessable shares of Common Stock as is equal to the
quotient obtained by dividing (A) the Liquidation Preference of such share(s)
of Series A Preferred Stock being converted by (B) the Conversion Price, as
last adjusted and then in effect, for the share(s) of such Series A Preferred
Stock being converted, by surrender of the certificates representing the
share(s) of Series A Preferred Stock so to be converted in the manner provided
in Section 5(b) hereof. The conversion price per share at which shares of
Common Stock shall be issuable upon conversion of shares of Series A Preferred
Stock shall initially be $4.50; provided, however, that such conversion price
shall be subject to adjustment as set forth in Section 5(d) hereof (such price,
as so adjusted from time to time, the "Conversion Price").

         (b) The holder of any shares of Series A Preferred Stock may exercise
the conversion right pursuant to Section 5(a) hereof as to any portion thereof
by delivering to the Corporation during regular business hours, at the office
of the Corporation or any transfer agent of the Corporation for the Series A
Preferred Stock as may be designated by the Corporation, the certificate or
certificates for the shares to be converted, duly endorsed or assigned in blank
or to the Corporation (if required by it), accompanied by written notice
stating that the holder elects to convert such shares or portion thereof and
stating the name or names (with address) in which the certificate or
certificates for the shares of Common Stock are to be issued. Conversion shall
be deemed to have been effected immediately prior to the close of business on
the date upon which the aforesaid delivery is made (the "Conversion Date"). As
promptly as practicable thereafter the Corporation shall issue and deliver to
or upon the written order of such holder, to the place designated by such
holder, a certificate to which such holder is entitled and a check or cash in
respect of any fractional interest in a share of Common Stock as provided in
Section 5(c) hereof. The person in whose name the certificate or certificates
for Common Stock are to be issued shall be deemed to have become a Common Stock
holder of record immediately prior to the close of business on the applicable

                                     - 5 -
<PAGE>

Conversion Date unless the transfer books of the Corporation are closed on that
date, in which event he shall be deemed to have become a Common Stock holder of
record immediately prior to the close of business on the next succeeding date
on which the transfer books are open, but the Conversion Price shall be that in
effect on the Conversion Date. Upon conversion of only a portion of the number
of shares covered by a certificate representing shares of Series A Preferred
Stock surrendered for conversion, the Corporation shall issue and deliver to or
upon the written order of the holder of the certificate so surrendered for
conversion, at the expense of the Corporation, a new certificate covering the
number of shares of the Series A Preferred Stock representing the unconverted
portion of the certificate so surrendered, which new certificate shall entitle
the holder thereof to dividends on the shares of Series A Preferred Stock
represented thereby to the same extent as if the portion of the certificate
theretofore covering such unconverted shares had not been surrendered for
conversion.

         (c) No fractional shares of Common Stock or scrip shall be issued upon
conversion of shares of Series A Preferred Stock. If more than one share of
Series A Preferred Stock shall be surrendered for conversion at any one time by
the same holder, the number of full shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number of
shares of such Series A Preferred Stock so surrendered. Instead of any
fractional shares of Common Stock which would otherwise be issuable upon
conversion of any shares of Series A Preferred Stock the Corporation shall pay
a cash adjustment in respect of such fractional interest in an amount equal to
the Closing Price on the relevant Conversion Date multiplied by such fractional
interest. Fractional interests shall not be entitled to dividends, and the
holders of fractional interests shall not be entitled to any rights as
stockholders of the Corporation in respect of such fractional interest.

         (d) The Conversion Price shall be subject to adjustment from time to
time as follows:

         (i) If the Corporation shall at any time, (1) pay a dividend on its
    outstanding Common Stock in shares of Common Stock or effect a distribution
    to holders of its outstanding Common Stock payable in shares of Common
    Stock, (2) subdivide the outstanding Common Stock, (3) combine the
    outstanding Common Stock into a smaller number of shares of Common Stock,
    or (4) issue any securities of the Company in a reclassification of the
    Common Stock (including any such reclassification in connection with a
    consolidation or merger in which the Company is the continuing or surviving
    corporation), the Conversion Price in effect immediately prior thereto
    shall be adjusted so that the registered holder of any share of Series A
    Preferred Stock thereafter surrendered for conversion shall be entitled to
    receive the number and kind of shares of Common Stock and other securities
    which such holder would have owned or have been entitled to receive after
    the happening of any of the events described above had such share been
    converted immediately prior to the happening of such event. An adjustment
    made pursuant to this subparagraph (i) shall become effective immediately
    after the Record Date in the case of a dividend and shall become effective
    immediately after the effective date in the case of a subdivision,
    combination or reclassification.

         (ii) If the Corporation shall at any time or from time to time after
    the Initial Issue Date, issue (x) shares of Common Stock, (y) rights,
    options, warrants or other

                                     - 6 -
<PAGE>

    securities entitling the holder thereof to subscribe for, purchase, convert
    to, exchange for or otherwise acquire Common Stock (excluding any such
    issuance that results in an adjustment under Section 5(d)(i) or 5(d)(iii)
    hereof) or (z) rights, options, warrants or other securities entitling the
    holder thereof to subscribe for, purchase, convert to, exchange for or
    otherwise acquire such convertible or exchangeable securities (in each case
    other than Excluded Securities and other than issuances that result in an
    adjustment under Section 5(d)(i) or 5(d)(iv) hereof), without consideration
    or for a consideration per share of Common Stock less than the Conversion
    Price in effect immediately prior to the issuance of such Common Stock or
    such rights, options, warrants or other securities, the Conversion Price in
    effect immediately prior to each such issuance shall forthwith be adjusted
    to a price equal to the quotient obtained by dividing:

         (A) an amount equal to the sum of

             (I) the total number of shares of Common Stock outstanding
       immediately prior to such issuance (including any shares of Common Stock
       deemed to have been issued pursuant to subdivisions (A) and (B) of
       Section 5(d)(ii)(3) (it being understood that the shares of Common Stock
       issuable upon conversion of the Series A Preferred Stock immediately
       prior to such issuance shall be deemed to be outstanding for all
       purposes of the computation required in this clause (A))) multiplied by
       the Conversion Price in effect immediately prior to such issuance, plus

             (II) the consideration received by the Corporation upon such
       issuance, by

         (B) the total number of shares of Common Stock outstanding (including
       any shares of Common Stock deemed to have been issued pursuant to
       subdivisions (A) and (B) of Section 5(d)(ii)(3) (it being understood
       that the shares of Common Stock issuable upon conversion of the Series A
       Preferred Stock immediately prior to such issuance shall be deemed to be
       outstanding for all purposes of the computation required in this clause
       (A))) immediately after the issuance of such Common Stock.

For the purposes of any adjustment of the Conversion Price pursuant to this
Section 5(d)(ii), the following provisions shall be applicable:

         (1) In the case of the issuance of Common Stock for cash, the
    consideration shall be deemed to be the amount of cash paid therefor after
    deducting therefrom any discounts, commissions or other expenses allowed,
    paid or incurred by the Corporation for any underwriting or otherwise in
    connection with the issuance and sale thereof.

         (2) In the case of the issuance of Common Stock for a consideration in
    whole or in part other than cash, the consideration other than cash shall
    be deemed

                                     - 7 -
<PAGE>

    to be the fair market value thereof as determined in good faith by the
    Board of Directors, irrespective of any accounting treatment.

         (3) In the case of (x) the issuance of rights, options or warrants
    entitling the holder thereof to subscribe for, purchase or otherwise
    acquire Common Stock, (y) securities convertible into or exchangeable for
    Common Stock or (z) rights, options, warrants or other securities
    convertible into or exchangeable for such convertible or exchangeable
    securities:

             (A) the aggregate maximum number of shares of Common Stock
       deliverable upon exercise of such rights, options or warrants entitling
       the holder thereof to subscribe for, purchase or otherwise acquire
       Common Stock shall be deemed to have been issued at the time such
       rights, options or warrants were issued and for a consideration equal to
       the consideration (determined in the manner provided in subdivisions (1)
       and (2) above), if any, received by the Corporation upon the issuance of
       such rights, options or warrants plus the minimum purchase price
       provided in such rights, options or warrants for the Common Stock
       covered thereby;

             (B) the aggregate maximum number of shares of Common Stock
       deliverable upon conversion of or in exchange for any such convertible
       or exchangeable securities or upon the exercise of rights, options or
       warrants to subscribe for, purchase or otherwise acquire such
       convertible or exchangeable securities and subsequent conversion or
       exchange thereof shall be deemed to have been issued at the time such
       rights, options, warrants or securities were issued and for a
       consideration equal to the consideration received by the Corporation for
       any such rights, options, warrants and securities (excluding any cash
       received on account of accrued interest or accrued dividends), plus the
       consideration, if any, to be received by the Corporation upon the
       conversion or exchange of such securities or the exercise of any related
       rights, options or warrants (the consideration in each case to be
       determined in the manner provided in subdivisions (1) and (2) above);

             (C) on any change in the number of shares of Common Stock
       deliverable upon exercise of any such rights, options or warrants or
       conversions of or exchanges for such convertible or exchangeable
       securities or any change in the consideration to be received by the
       Corporation upon the exercise of any such rights, options or warrants or
       conversions of or exchanges for such convertible or exchangeable
       securities, other than a change resulting from the anti-dilution
       provisions thereof, the Conversion Price shall forthwith be readjusted
       to such Conversion Price as would have obtained had the adjustment made
       upon the issuance of such rights, options, warrants or securities not
       converted prior to such change been made upon the basis of such change;
       and

             (D) on the expiration of any such rights, options or warrants, the
       termination of any such rights to convert or exchange or the expiration
       of any rights, options or warrants related to such convertible or
       exchangeable

                                     - 8 -
<PAGE>

       securities, the Conversion Price shall forthwith be readjusted to such
       Conversion Price as would have obtained had the adjustment made upon the
       issuance of such rights, options, warrants or securities or rights,
       options or warrants related to such securities been made upon the basis
       of the issuance of only the number of shares of Common Stock actually
       issued upon exercise of such rights, options or warrants, upon the
       conversion or exchange of such securities or upon the exercise of the
       rights, options or warrants related to such securities and subsequent
       conversion or exchange thereof.

         (iii) In case the Corporation shall distribute to all holders of its
    Common Stock any shares of capital stock of the Corporation (other than
    Common Stock) or evidences of its indebtedness or assets (including cash)
    or rights, options, warrants or other securities entitling them to
    subscribe for, purchase, convert to, exchange for or otherwise acquire
    Common Stock any of its securities (excluding those referred to in Section
    5(d)(i), 5(d)(ii) or 5(d)(iv)), then in each such case, the Conversion
    Price shall be adjusted so that the same shall equal the price determined
    by multiplying (I) the Conversion Price in effect immediately prior to the
    date of such distribution by (II) a fraction, the numerator of which shall
    be such Conversion Price less the fair market value (as determined by the
    Board of Directors, whose determination shall, if made in good faith, be
    conclusive) of the portion of the capital stock, assets, evidences of
    indebtedness or rights, options, warrants or other securities so
    distributed applicable to one share of Common Stock, and the denominator of
    which shall be such Conversion Price. Such adjustment shall become
    effective immediately after the Record Date for the determination of
    shareholders entitled to receive such distribution.

         (iv) In case of any capital reorganization or any reclassification of
    the stock of the Corporation (other than a change in par value or from par
    value to no par value or from no par value to par value or as a result of a
    stock dividend or subdivision, split-up or combination of shares) or the
    consolidation or merger of the Corporation with or into another Person
    (other than a consolidation or merger in which the Corporation is the
    continuing corporation and which does not result in any change in the
    Common Stock) or of the sale or other disposition of all or substantially
    all the properties and assets of the Corporation as an entirety to any
    other Person, or the effectuation by the Corporation of a transaction or
    series of related transactions in which 50% or more of the voting power of
    the Corporation is disposed of, each share of Series A Preferred Stock
    shall after such reorganization, reclassification, consolidation, merger,
    sale or other disposition be convertible into the kind and number of shares
    of stock or other securities or property of the Corporation or of the
    corporation resulting from such consolidation or surviving such merger or
    to which such properties and assets shall have been sold or otherwise
    disposed to which the holder of the number of shares of Common Stock
    deliverable (immediately prior to the time of such reorganization,
    reclassification, consolidation, merger, sale or other disposition) upon
    conversion of such shares would have been entitled upon such
    reorganization, reclassification, consolidation, merger, sale or other
    disposition. The provisions of this Section 5 shall similarly apply to
    successive reorganizations, reclassifications, consolidations, mergers,
    sales or other dispositions.

         (e) Whenever the Conversion Price shall be adjusted as provided in
Section 5(d) the Corporation shall forthwith file, at the office of the
Corporation or any transfer agent designated by the Corporation for the Series
A Preferred Stock, a statement, signed by its chief financial officer, showing
in detail the facts requiring such adjustment and the Conversion Price then in
effect. The Corporation shall also cause a copy of such statement to be sent by
first-class certified mail, return receipt requested, postage prepaid, to each
holder of shares of Series A Preferred Stock at his or its address appearing on
the Corporation's records. Where appropriate, such copy may be given in advance
and may be included as part of a notice required to be mailed under the
provisions of Section 5(f).

         (f) In the event the Corporation shall propose to take any action of
the types described in Section 5(d), the Corporation shall give notice to each
holder of shares of Series A Preferred Stock, in the manner set forth in
Section 5(e), which notice shall specify the record date, if any, with respect
to such action and the date on which such action is to take place. Such notice
shall also set forth such facts with respect thereto as shall be reasonably
necessary to indicate the effect of such action (to the extent such effect may
be at the date of such notice) on the Conversion Price and the number, kind or
class of shares or other securities or property which shall be deliverable or
purchasable upon the occurrence of such action or deliverable upon conversion
of shares of Series A Preferred Stock. In the case of any action which would
require the fixing of a record date, such notice shall be given at least 20
days prior to the date so fixed, and in case of all other action, such notice
shall be given at least 30 days prior to the taking of such proposed action.
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of any such action.

         (g) The Corporation shall pay all documentary, stamp and other
transactional taxes attributable to the issuance of shares of capital stock of
the Corporation upon conversion of any shares of Series A Preferred Stock if
issued in the name of the record holder; otherwise, such amounts shall be paid
by the holder of such shares of Series A Preferred Stock.

         (h) The Corporation shall reserve, free from preemptive rights, out of
its authorized but unissued shares of Common Stock solely for the purpose of
effecting the conversion of the shares of Series A Preferred Stock sufficient
shares to provide for the conversion from time to time of all outstanding
shares of Series A Preferred Stock.

         (i) All shares of Common Stock which may be issued in connection with
the conversion provisions set forth herein will, upon delivery by the
Corporation, be duly and validly issued, fully paid and nonassessable, with no
personal liability attaching to the ownership thereof, and free from all taxes,
liens or charges with respect thereto and not subject to any preemptive rights.

         SECTION 6. Automatic Conversion. Upon the occurrence of an Event of
Conversion, all shares of Series A Preferred Stock then outstanding shall, by
virtue of and simultaneously with the occurrence of the Event of Conversion and
without any action on the part of the holders thereof, be deemed automatically
converted into that number of fully paid and nonassessable shares of Common
Stock into which such shares would have been convertible in the event of
optional conversion at such time pursuant to Section 5 hereof.

         SECTION 7. Voting. (a) In addition to the rights hereinafter specified
in this Section 7 and any other rights provided by law or the By-laws of the
Corporation, each share of Series A Preferred Stock shall entitle the holder
thereof to such number of votes per share as shall equal the number of shares
of Common Stock (rounded to the nearest whole number) into which such share of
Series A Preferred Stock is then convertible as provided in Section 5 hereof,
entitled to vote on all matters as to which holders of Common Stock shall be
entitled to vote, in the same manner and with the same effect as such holders
of Common Stock, voting together on all matters with the holders of Common
Stock as one class.

         (b) In addition to the rights specified in Section 7(a) hereof, the
holders of at least 51% in voting power of the Series A Preferred Stock, voting
separately as one class, shall have the special and exclusive right to elect
one director to the Board of Directors of the Corporation for so long as at
least 250,000 shares of Series A Preferred Stock are outstanding (as adjusted
for stock splits, stock dividends, stock combinations, recapitalizations and
like occurrences). In any election of directors pursuant to this Section 7 (b),
each holder of shares of Series A Preferred Stock shall be entitled to one vote
for each share of Series A Preferred Stock held by such holder. The special and
exclusive voting right of the holders of the Series A Preferred Stock, voting
separately as one class, contained in this paragraph (b) may be exercised
either at a special meeting of the holders of Series A Preferred Stock called
as provided below, or at any annual or special meeting of the stockholders of
the Corporation, or by written consent of such holders in lieu of a meeting.
The director to be elected pursuant to this Section 7(b) shall serve for a term
extending from the date of his election and qualification until the time of the
next succeeding annual meeting of stockholders or until his successor has been
elected and qualified, whichever is sooner. The director to be elected pursuant
to this Section 7(b) may be removed, with or without cause, only by the holders
of at least 51% in voting power of the Series A Preferred Stock.

         (c) If at any time the directorship to be filled by the holders of
Series A Preferred Stock pursuant to Section 7(b) hereof has been vacant for a
period of ten or more days, the Secretary of the Corporation shall deliver a
notice of such vacancy to such holders of Series A Preferred Stock and, upon
the written request of the holders of record of shares representing at least
ten percent of the voting power of the Series A Preferred Stock then
outstanding, call a special meeting of the holders of Series A Preferred Stock
for the purpose of electing a director to fill such vacancy. Such meeting shall
be held at the earliest practicable date at such place as is specified in or
determined in accordance with the By-laws of the Corporation. If such meeting
shall not be called by the Secretary of the Corporation within ten days after
receipt of said written request, then the holders of record of shares
representing at least ten percent of the voting power of the Series A Preferred
Stock then outstanding may designate in writing one holder to call such meeting
at the expense of the Corporation, and such meeting may be called by such
person so designated upon the notice required for annual meetings of
stockholders and shall be held at such specified place. Any holder of Series A
Preferred Stock so designated shall have access to the stock books of the
Corporation relating to the Series A Preferred Stock for the purpose of calling
a meeting of the stockholders pursuant to these provisions.

         (d) At any meeting held for the purpose of electing a director as
provided in Section 7(b) hereof, the presence, in person or by proxy, of the
holders of record of shares

                                     - 11 -
<PAGE>

representing at least 51% of the voting power of the Series A Preferred Stock
then outstanding shall constitute a quorum of the Series A Preferred Stock for
such election. At any such meeting or adjournment thereof, the absence of a
quorum of the Series A Preferred Stock shall not prevent the election of
directors other than the director to be elected by holders of Series A
Preferred Stock pursuant to Section 7(b) hereof, and the absence of a quorum
for the election of such other directors shall not prevent the election of the
director to be elected by the holders of Series A Preferred Stock pursuant to
Section 7(b) hereof, and in the absence of either or both of such quorums, the
holders of record of shares representing at least 51% of the voting power
present in person or by proxy of the class of stock which lacks a quorum shall
have power to adjourn the meeting for the election of directors which they are
entitled to elect from time to time without notice other than announcement at
the meeting. A vacancy in the directorship to be elected by the holders of the
Series A Preferred Stock pursuant to Section 7(b) hereof may be filled only by
vote or written consent in lieu of a meeting of the holders of at least 51% of
the voting power of the Series A Preferred Stock.

         (e) The Corporation shall not, without the affirmative consent or
approval of the holders of shares representing at least 51%, by voting power,
of the Series A Preferred Stock then outstanding, voting separately as one
class, given by written consent in lieu of a meeting or by vote at a meeting
called for such purpose for which notice shall have been given to the holders
of the Series A Preferred Stock in the manner provided in the By-laws of the
Corporation:

         (i) designate or issue any additional shares of Series A Preferred
    Stock or in any manner authorize, create, designate, issue or sell any
    class or series of capital stock (including any shares of treasury stock)
    or rights, options, warrants or other securities convertible into or
    exercisable or exchangeable for capital stock (other than Excluded
    Securities) or any debt security which by its terms is convertible into or
    exchangeable for any equity security or has any other equity feature or any
    security that is a combination of debt and equity, which, in each case, as
    to the payment of dividends, distribution of assets or redemptions,
    including, without limitation, distributions to be made upon the
    liquidation, dissolution or winding up of the Corporation or a merger,
    consolidation or sale of the assets thereof, is senior to or on a parity
    with the Series A Preferred Stock or which in any manner adversely affects
    in any material respect the rights of the holders of the Series A Preferred
    Stock in their capacity as such;

         (ii) in any manner alter or change the terms, designations, powers,
    preferences or relative, participating, optional or other special rights,
    or the qualifications, limitations or restrictions, of the Series A
    Preferred Stock;

         (iii) reclassify the shares of any class or series of Junior Stock
    into shares of any class or series of capital stock (A) ranking, either as
    to payment of dividends, distributions of assets or redemptions, including,
    without limitation, distributions to be made upon the liquidation,
    dissolution or winding up of the Corporation or a merger, consolidation or
    sale of the assets thereof, senior to or on a parity with the Series A
    Preferred Stock or (B) which in any manner adversely affects in any
    material respect the rights of the holders of Series A Preferred Stock in
    their capacity as such;

                                     - 12 -
<PAGE>

         (iv) sell, abandon, transfer, lease or otherwise dispose of all or
    substantially all of its properties or assets or merge or consolidate with
    or into, or permit any subsidiary to merge with or into any other
    corporation, corporations, entity or entities;

         (v) take any action to voluntarily dissolve, liquidate or wind up or
    carry out any partial liquidation or distribution or transaction in the
    nature of a partial liquidation or dissolution; or

         (vi) take any action to cause any amendment, alteration or repeal of
    any of the provisions of (i) the Certificate of Incorporation or (ii) the
    By-laws, if such amendment, alteration or repeal could adversely affect in
    any material respect the rights of the holders of the Series A Preferred
    Stock in their capacity as such or the director elected by the holders of
    the Series A Preferred Stock.

         SECTION 8. Ranking. Any and all classes of capital stock of the
Corporation, whether now existing or hereafter created, shall be deemed to rank
junior to the Series A Preferred Stock as to dividends and as to the
distribution of assets upon liquidation, dissolution or winding up.

         SECTION 9. No Redemption. The shares of Series A Preferred Stock shall
not be redeemable under any circumstances whatsoever, except (i) as provided in
Section 4 hereof or (ii) to the extent otherwise agreed to in writing by the
Corporation and the holders of any such shares.

         SECTION 10. Notices. Unless otherwise specified in the Certificate of
Incorporation or the By-laws, all notices or communications given hereunder
shall be in writing and, if to the Corporation, shall be delivered to it at its
principal executive offices, and if to any holder of Series A Preferred Stock,
shall be delivered to it at its address as it appears on the stock books of the
Corporation.

         5. The foregoing amendment to the Certificate of Incorporation was
authorized by the Board of Directors of the Corporation at a meeting of the
Board, pursuant to the authority expressly vested in it in the Corporation's
Certificate of Incorporation.
