                 2000 PROFESSIONAL EMPLOYEE STOCK PURCHASE PLAN

         1. Purpose of the Plan. The purpose of the 2000 Professional Employee
Stock Purchase Plan is to secure for OptiCare Health Systems, Inc. (the Company)
and its stockholders the benefits of the incentive inherent in the ownership of
the Company's common stock by present and future employees of the Company and
its subsidiaries and affiliates.

         2. Shares Reserved for the Plan. There shall be reserved for issuance
and purchase under the Plan an aggregate of 450,000 shares of common stock of
the Company ("common stock"), subject to adjustment as provided in Section 11.
Notwithstanding the foregoing, the number of shares of common stock available
for issuance and purchase under the Plan shall be reduced by the number of
shares of common stock issued under the Company's 1999 Employee Stock Purchase
Plan. Shares subject to the Plan may be shares now or hereafter authorized but
unissued, or shares that were once issued and subsequently reacquired by the
Company.

         3. Administration of the Plan. The Plan shall be administered at the
expense of the Company by a committee appointed by the board of directors of the
Company (the "Board") consisting of not less than two members of the Board who
shall serve at the pleasure of the Board and which shall be designated as the
Compensation Committee (hereinafter referred to as the "Committee"). No member
of the Committee shall be eligible to participate in the Plan. Subject to the
express provisions of the Plan, the Committee shall have authority to interpret
the Plan, to prescribe, amend and rescind rules and regulations relating to it,
and to make all other determinations necessary or advisable in administering the
Plan, all of which determinations shall be final and binding upon all persons
unless otherwise determined by the board of directors. A quorum of the Committee
shall consist of a majority of its members and the Committee may act by vote of
a majority of its members at a meeting at which a quorum is present, or without
a meeting by a written consent to the action taken signed by all members of the
Committee.

         4. Eligible Employees. All employees of the Company, its subsidiaries
and affiliates, including, but not limited to, OptiCare, P.C. and Optometric Eye
Care Center, P.A. and their respective subsidiaries, shall be eligible to
participate in the Plan, provided each of such employees:

         a.   has customary employment of a minimum of 20 hours per week,

         b.   has customary employment for more than five months in a calendar
              year, and

         c.   does not own, immediately after the right is granted, stock
              possessing 5% or more of the total combined voting power or value
              of all classes of stock of the Company or a subsidiary company.

         In determining whether a company is a subsidiary, the rules of Section
424(f) of the Code

<PAGE>

shall be followed, and in determining stock ownership under this paragraph the
rules of Section 424(d) of the Internal Revenue Code of 1986, as amended (the
"Code"), shall apply and stock which the employee may purchase under outstanding
options shall be treated as stock owned by the employee. Employees eligible to
participate in the Plan pursuant to the provisions of this Section 4 are
hereinafter referred to as "Eligible Employees".

         5. Election to Participate. Each Eligible Employee may participate in
the Plan by filing with the Committee an election to purchase form (the "Form")
authorizing specified regular payroll deductions. Payroll deductions may be in
any amount specified by an employee, but the annual rate of deductions may not
exceed 20% of the employee's annual rate of base compensation (as defined by the
Committee) in effect at the time of the filing of the Form. All regular payroll
deductions shall be credited to a non-interest bearing account which the Company
shall establish in the name of each participant ("Payroll Deduction Account").
Eligible Employees who so elect to participate in the Plan are hereinafter
referred to as "Participating Employees."

         All funds in Payroll Deduction Accounts may be used by the Company for
any corporate purpose, subject to the right of a Participating Employee to
withdraw at any time an amount equal to the balance accumulated in the
employee's Payroll Deduction Account. A Participating Employee may at any time,
but not more than once during any calendar quarter, increase or decrease the
employee's payroll deduction by filing a new Form which shall become effective
on the following payroll date.

          6. Limitation on Number of Shares Which an Employee May Purchase. No
Eligible Employee may be granted an option under the Plan that permits the
employee to purchase stock under the Plan (and any other employee stock purchase
plans qualified under Section 423 of the Code and sponsored by the Company or
any of its subsidiaries) at a rate which exceeds $25,000 in fair market value of
such stock (determined at the time the option is granted) for each calendar year
in which any such option granted to such individual is outstanding at any time.

         The foregoing limitation shall be interpreted by the Committee in
accordance with applicable rules and regulations issued under the Code.

          7. Purchase Price. The Purchase Price for each share of common stock
shall be 85% (or such higher percentage as the Committee may determine from time
to time) of the fair market value of such share on the Investment Date as
hereinafter defined, provided that the Purchase Price shall in no event be less
than the par value of such share.

         Fair market value on a given date means (i) if the common stock is
listed on a national securities exchange, the mean between the highest and
lowest sale prices reported as having occurred on the primary exchange on which
the common stock is listed and traded on the date prior to such date, or, if
there is no such sale on that date, then on the last preceding date on which
such a sale was reported; (ii) if the common stock is not listed on any national
securities

                                       2

<PAGE>

exchange but is quoted in the National Market System of The Nasdaq Stock Market
on a last sale basis, the average between the high bid price and low ask price
reported on the date prior to such date, or, if there is no such sale on that
date, then on the last preceding date on which a sale was reported; or (iii) if
the common stock is not listed on a national securities exchange nor quoted in
the National Market System of The Nasdaq Stock Market on a last sale basis, the
amount determined by the Committee to be the fair market value based upon a good
faith attempt to value the common stock accurately.

          8. Method of Purchase and Investment Accounts. The last business day
of the third month in each calendar quarter commencing on or after the effective
date of the Plan shall be known as an Investment Date. Each Participating
Employee having funds in the employee's Payroll Deduction Account on an
Investment Date shall be deemed, without any further action, to have been
granted and have exercised such employee's right to purchase one or more full or
fractional shares which the funds in such employee's Payroll Deduction Account
could purchase at the Purchase Price on such Investment Date, subject to the
restrictions set forth in Section 6. All full or fractional shares so purchased
shall be credited to each Participating Employee and any balance in the
employee's Payroll Deduction Account, if any, shall be retained in such Account.

          9. Rights as a Stockholder. Upon each Investment Date, or as soon
thereafter as practicable, a certificate for each share of common stock credited
to the employee will be forwarded to the employee or such full shares and
fractional shares will otherwise be credited to the employee. In the event a
Participating Employee terminates his or her Payroll Deduction Account, any
fractional shares credited to the Participating Employee will be paid to such
employee in cash.

         10. Rights Not Transferable. Rights under the Plan are not transferable
by a Participating Employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

         11. Adjustment for Changes in the Company's Stock. In the event of a
subdivision of outstanding shares of common stock, or the payment of a stock
dividend thereon, the number of shares reserved or authorized to be reserved
under the Plan shall be increased proportionately, and such other adjustment
shall be made as may be deemed necessary or equitable by the Committee. In the
event of any other change affecting the common stock, such adjustments shall be
made as may be deemed equitable by the Committee to give proper effect to such
event subject to the limitations of Section 424 of the Code.

         12. Retirement, Termination and Death. In the event of a Participating
Employee's retirement or other termination of employment, or in the event that
the employee otherwise ceases to be an Eligible Employee, the amount in the
employee's Payroll Deduction Account shall be refunded to the employee and, in
the event of death, shall be paid to the employee's designated beneficiary under
the Plan.

                                       3

         13. Amendment of the Plan. The board of directors may at any time amend
the Plan in any respect, except that, without the approval of the stockholders
of the Company, no amendment shall be made changing the number of shares to be
reserved under the Plan (other than as provided in Section 11) to an amount
which would require shareholder approval under the rules of the American Stock
Exchange or such other exchange or National Market System that the Company's
common stock is then listed.

         14. Termination of the Plan. The Plan and all rights of employees
hereunder shall terminate:

              (a)    on the Investment Date that Participating Employees become
                     entitled to purchase a number of shares greater than the
                     number of reserved shares remaining available for purchase:
                     or

              (b)    at any time, at the discretion of the board of directors,
                     effective as of the completion of any calendar quarter.

         In the event that the Plan terminates under circumstances described in
(a) above, reserved shares remaining as of the termination date shall be issued
to Participating Employees on a pro rata basis.

         15. Effective Date of the Plan. The Plan shall become effective on
March 27, 2000.

         16. Government and Other Regulations. The Plan, and the grant and
exercise of the rights to purchase shares hereunder, and the Company's
obligation to sell and deliver shares upon the exercise of rights to purchase
shares, shall be subject to all applicable Federal, State and foreign laws,
rules and regulations, and to such approvals by any regulatory or government
agency as may, in the opinion of counsel for the Committee, be required.

         17. Tax. The Plan is not intended to comply with the provisions of
Section 423 of the Code and, as such, Participating Employees will not receive
favorable tax treatment provided under the Code when the common stock is sold.

                 AGREEMENT AND PLAN OF MERGER AND REORGANIZATION

         AGREEMENT AND PLAN OF MERGER AND REORGANIZATION, dated as of February

this Agreement;

         WHEREAS, concurrently with the execution of this Agreement and as an

meanings to be equally applicable to the singular and plural forms of the terms
defined):

         "Adjusted Financial Statements" shall mean the Company's month-ending

Common Stock issuable pursuant to Section 3.01(a) in exchange for shares of
Company Common Stock outstanding immediately prior to the Effective Time; (ii)
sufficient

                                       11
<PAGE>

funds to permit payment in lieu of fractional shares pursuant to Section 3.04
and (iii) any dividends or distributions to which holders of shares of Company
Common Stock may be entitled pursuant to Section 3.07.

         (c) Exchange Procedures. The Exchange Agent shall mail to each holder
of record of certificates of Company Common Stock ("Company Certificates"),
whose shares were converted into the right to receive shares of Parent Common
Stock (and cash in lieu of fractional shares pursuant to Section 3.04) promptly
after the Effective Time (and in any event no later than three Business Days
after the later to occur of the Effective Time and receipt by Parent of a
complete list from the Company of the names and addresses of its holders of
record): (i) a letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Company Certificates shall pass,
only upon receipt of the Company Certificates by the Exchange Agent, and shall
be in such form and have such other provisions as Parent may reasonably
specify); and (ii) instructions for use in effecting the surrender of the
Company Certificates in exchange for Parent Certificates (and cash in lieu of
fractional shares). Upon surrender of a Company Certificate for cancellation to
the Exchange Agent or to such other agent or agents as may be appointed by
Parent, together with such letter of transmittal, duly completed and validly
executed, and such other documents as may be reasonably required by the Exchange
Agent, the holder of such Company Certificate shall be entitled to receive in
exchange therefor a Parent Certificate representing the number of whole shares
of Parent Common Stock that such holder has the right to receive pursuant to
this Article III and payment of cash in lieu of fractional shares which such
holder has the right to receive pursuant to Section 3.04, and the Company
Certificate so surrendered shall forthwith be canceled. Until so surrendered,
each outstanding Company Certificate that, prior to the Effective Time,
represented shares of Company Common Stock will be deemed from and after the
Effective Time, for all corporate purposes other than the payment of dividends
and distributions, to evidence the ownership of the number of full shares of
Parent Common Stock into which such shares of Company Common Stock shall have
been so converted and the right to receive an amount in cash in lieu of the
issuance of any fractional shares in accordance with Section 3.04.
Notwithstanding any other provision of this Agreement, no interest will be paid
or will accrue on any cash payable to holders of Company Certificates pursuant
to the provisions of this Article III.

         (d) Lost, Stolen or Destroyed Company Certificates. In the event any
Company Certificates shall have been lost, stolen or destroyed, the Exchange
Agent shall issue in exchange for such lost, stolen or destroyed Company
Certificates, upon the making of an affidavit of that fact by the holder
thereof, a Parent Certificate representing such shares of Parent Common Stock
(and cash in lieu of fractional shares) as may be required pursuant to this
Article III; provided, however, that Parent may, in its discretion and as a
condition precedent to the issuance thereof, require the owner of such lost,
stolen or destroyed Company Certificates to indemnify Parent against any claim
that may be made against Parent, the Surviving Corporation or the Exchange Agent
with respect to the Company Certificates alleged to have been lost, stolen or
destroyed.

         (e) Distributions With Respect to Unexchanged Shares. No dividends or
other distributions with respect to Parent Common Stock with a record date after
the Effective Time will be paid to the

                                       12
<PAGE>

holder of any unsurrendered Company Certificate with respect to the shares of
Parent Common Stock represented thereby until the holder of record of such
Company Certificate shall surrender such Company Certificate. Subject to the
effect of applicable escheat or similar laws, following surrender of any such
Company Certificate, there shall be paid to the record holder of the Parent
Certificates issued in exchange therefor, without interest, at the time of such
surrender, the amount of any such dividends or other distributions with a record
date after the Effective Time theretofore payable (but for the provisions of
this Section 3.02(e)) with respect to such shares of Parent Common Stock.

         (f) Transfer of Ownership. If any Parent Certificate is to be issued in
a name other than that in which the Company Certificate surrendered in exchange
therefor is registered, it will be a condition of the issuance thereof that the
Company Certificate so surrendered will be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange will have
paid to Parent or any agent designated by it any transfer or other taxes
required by reason of the issuance of a Parent Certificate for shares of Parent
Common Stock in any name other than that of the registered holder of the Company
Certificate surrendered, or established to the satisfaction of Parent or any
agent designated by it that such tax has been paid or is not payable.

         (g) Termination of Exchange Agent Funding. Any portion of funds
(including any interest earned thereon) or Parent Certificates held by the
Exchange Agent which have not been delivered to holders of Company Certificates
pursuant to this Article III within six months after the Effective Time shall
promptly be paid or delivered, as appropriate, to Parent, and thereafter holders
of Company Certificates who have not theretofore complied with the exchange
procedures outlined in and contemplated by this Section 3.02 shall thereafter
look only to Parent (subject to abandoned property, escheat and similar laws)
only as general creditors thereof for their claim for shares of Parent Common
Stock, any cash in lieu of fractional shares of Parent Common Stock and any
dividends or distributions (with a record date after the Effective Time) with
respect to Parent Common Stock to which they are entitled.

         (h) No Liability. Notwithstanding anything to the contrary in this
Section 3.02, none of the Exchange Agent, the Surviving Corporation or any party
hereto shall be liable to any person in respect of any shares of Parent Common
Stock or cash delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

         (i) Expenses of Exchange Agent. Parent shall pay all charges and
expenses of the Exchange Agent incurred solely in connection with the
transactions contemplated by this Agreement, to the extent of $8,500, with any
and all charges and expenses above such amount being borne by the Company.

         SECTION 3.03  Stock Transfer Books

         (a) At the Effective Time, the stock transfer books of Company shall
each be closed, and there shall be no further registration of transfers of
shares of

                                       13
<PAGE>

Company Common Stock thereafter on the records of any such stock transfer books.
In the event of a transfer of ownership of shares of Company Common Stock that
is not registered in the stock transfer records of Company at the Effective
Time, a certificate or certificates representing the number of full shares of
Parent Common Stock into which such shares of Company Common Stock shall have
been converted shall be issued to the transferee together with a cash payment in
lieu of fractional shares, if any, in accordance with Section 3.04 hereof, and a
cash payment in the amount of dividends, if any, in accordance with Section
3.02(e) hereof, if the certificate or certificates representing such shares of
Company Common Stock is or are surrendered as provided in Section 3.02(c)
hereof, accompanied by all documents required to evidence and effect such
transfer and by evidence of payment of any applicable stock transfer tax.

         (b) Notwithstanding anything to the contrary herein, certificates
surrendered for exchange by any person constituting an affiliate of Company
shall not be exchanged until Parent shall have received from such person an
affiliate letter as provided in Section 7.03.

         SECTION 3.04  No Fractional Share Certificates

         No scrip or fractional share Parent Certificate shall be issued upon
the surrender for exchange of Company Certificates, and an outstanding
fractional share interest shall not entitle the owner thereof to vote, to
receive dividends or to any rights of a stockholder of Parent or of Surviving
Corporation with respect to such fractional share interest. As promptly as
practicable following the Effective Time, Parent shall deposit with the Exchange
Agent an amount in cash sufficient for the Exchange Agent to pay each holder of
Company Common Stock an amount in cash equal to the product obtained by
multiplying (i) the fractional share interest to which such holder would
otherwise be entitled (after taking into account all shares of Company Common
Stock held at the Effective Time by such holder) by (ii) the closing price for a
share of Parent Common Stock on the American Stock Exchange (the "AMEX") on the
last Business Day prior to the Effective Time. As soon as practicable after the
determination of the amount of cash, if any, to be paid to holders of Company
Common Stock with respect to any fractional share interests, the Exchange Agent
shall make available such amounts, net of any required withholding Taxes, to
such holders of Company Common Stock, subject to and in accordance with the
terms of Section 3.02 hereof.

         SECTION 3.05  Options to Purchase Company Common Stock

         (a) At or prior to the Effective Time, each of Company and Parent shall
take all action necessary to cause as of the Effective Time the assumption by
Parent of, or the reissuance by Parent of substitutes for, all of the following
which remain outstanding as of the Effective Time: (i) the options to purchase
Company Common Stock listed in the Company Disclosure Schedule, whether vested
or unvested, and issued under Company's Stock Plans; (ii) options to purchase
Company Common Stock listed in the Company Disclosure Schedule pursuant to
option agreements outside of the Company's Stock Plans; and (iii) the warrants
to purchase Company Stock listed in the Company Disclosure Schedule and issued
pursuant to warrant agreements, (collectively, the "Outstanding Options and
Warrants," and each an "Outstanding Option" or an "Outstanding Warrant"). To the
fullest extent permitted under applicable law and the applicable stock option

                                       14
<PAGE>

agreements, the Company Stock Plans and the warrant agreements, each of the
Outstanding Options and Outstanding Warrants shall be exchanged or substituted
without any action on the part of the holder thereof into an option or warrant
to purchase shares of Company Common Stock as of the Effective Time. The number
of shares of Parent Common Stock that the holder of an assumed or substituted
Outstanding Option or Outstanding Warrant shall be entitled to receive upon the
exercise of such option or warrant shall be the same number of shares of Company
Common Stock as the holder of such Outstanding Option or Outstanding Warrant
would have been entitled to receive pursuant to the Merger had such holder
exercised such option or warrant in full immediately prior to the Effective
Time. The price per share of Parent Common Stock after the Effective Time shall
be equal to (x) the aggregate exercise price for the shares of Company Common
Stock otherwise purchasable pursuant to such Outstanding Option or Outstanding
Warrant divided by (y) the Exchange Ratio. Other than as set forth in the
Outstanding Options and Warrants or as contemplated by this Agreement, the
assumption and substitution of options and warrants as provided herein shall not
give the holders of such options and warrants additional benefits or additional
vesting rights which they did not have immediately prior to the Effective Time
or relieve the holders of any obligations or restrictions applicable to their
options and warrants or the shares obtainable upon exercise of their options and
warrants. Only whole shares of Company Common Stock shall be issued upon
exercise of any Outstanding Option or Outstanding Warrant, and no certificates
or scrip representing fractional shares of Company Common Stock and no cash in
lieu of fractional shares shall be issued upon such exercise. All fractional
shares of Company Common Stock which a holder of any Outstanding Option or
Outstanding Warrant would otherwise be entitled to receive upon exercise thereof
shall be aggregated at the time of such exercise. If a fractional share results
from such aggregation, in lieu thereof such fraction shall be rounded up to one
whole share of Company Common Stock if it is one-half or larger and shall be
rounded down to zero and canceled without any payment or distribution with
respect thereto if it is less than one-half. Prior to the Effective Time,
Company and Parent shall take such additional actions, if any, as are necessary
under applicable law and the applicable agreements and the Company Stock Plans
to assure that each Outstanding Option and Outstanding Warrant shall, from and
after the Effective Time, represent only the right to purchase, upon exercise,
whole shares of Company Common Stock. Prior to the Effective Time, the Board of
Directors of the Company shall make the determination that neither the Merger
nor any of the other transactions contemplated by this Agreement shall be deemed
a "Change in Control" for purposes of each of the employment agreements entered
into by the Company other than the employment agreements set forth on Section
3.05 of the Company Disclosure Schedule.

         Except as otherwise specifically identified in Section 3.05 of the
Company Disclosure Schedule, the assumption of the Outstanding Options and
Warrants in the Merger and their conversion into options and warrants for Parent
Common Stock will not result in any accelerated vesting of those options or
warrants or the shares purchasable thereunder and the vesting schedule in effect
for such Outstanding Options and Warrants immediately prior to the Effective
Time shall remain in full force after the assumption thereof by Parent.

         It is the Parent's intention to roll such converted Outstanding Options
into options to purchase Parent Common Stock, as described above, pursuant to
either the Parent's Performance

                                       15
<PAGE>

Stock Program or, at Parent's discretion or in the event that Parent is unable
to roll such converted options into the Performance Stock Program, then Parent
will assume the Company Stock Plans. Upon such conversion, any options granted
under the Performance Stock Program to the former holders of Outstanding Options
pursuant to the Company Stock Plans shall, except to the extent provided above,
in all respects be subject to the terms, provisions and conditions of the
Performance Stock Program and the standard form of stock option agreement
relating to such Performance Stock Program except where the terms of the
Performance Stock Program are contrary to the rights of an option holder,
whereupon in such instance the option holder will retain his or her rights to
such contrary terms; and provided further, that such holders shall be deemed to
have been granted such options as of the date the original options were granted
under the Company Stock Plans.

         (b) As soon as practicable after the Effective Time, Parent shall file
a registration statement on Form S-8 or a successor form, under the Securities
Act with respect to the shares of Parent Common Stock subject to the Outstanding
Options, to the extent that Form S-8 or successor form, is available to register
the Outstanding Options, and shall use its reasonable efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as the Outstanding Options remain outstanding.

         SECTION 3.06  Unvested Stock

         At the Effective Time, any unvested shares of Company Common Stock,
including, but not limited to, any restricted stock, awarded to employees,
directors or consultants pursuant to any of the Company's plans or arrangements
and outstanding immediately prior to the Effective Time shall be converted into
unvested shares of Parent Common Stock in accordance with the Exchange Ratio and
shall remain subject to the same terms, restrictions and vesting schedule as in
effect immediately prior to the Effective Time. All outstanding rights which
Company may hold immediately prior to the Effective Time to repurchase unvested
shares of Company Common Stock shall be assigned to the Parent in the Merger and
shall thereafter be exercisable by Parent upon the same terms and conditions in
effect immediately prior to the Effective Time, except that the shares
purchasable pursuant to such rights and the purchase price payable per share
shall be adjusted to reflect the Exchange Ratio.

         SECTION 3.07  Certain Adjustments

         If between the date of this Agreement and the Effective Time, the
outstanding shares of Parent Common Stock or Company Common Stock shall be
changed into a different number of shares by reason of any reclassification,
recapitalization, split-up, combination or exchange of shares, or any dividend
payable in stock or other securities shall be declared thereon with a record
date within such period, or the number of shares of Company Common Stock on a
fully diluted basis is in excess of that specified in Section 4.03 and disclosed
in Section 4.03 of the Company Disclosure Schedule (regardless of whether such
excess is a result of an additional issuance of capital stock or a correction to
such Sections), then the Exchange Ratio established pursuant to the provisions
of

                                       16
<PAGE>

Section 3.01 shall be adjusted accordingly to provide to each of Parent, on the
one hand, and the holders of Company Common Stock in the aggregate, on the other
hand, the same economic effect as contemplated by this Agreement prior to such
reclassification, recapitalization, split-up, combination, exchange, dividend or
increase.

Company Subsidiary is duly qualified or licensed to do business, and is in good
standing (to the extent applicable), in each jurisdiction where the character of
the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except for such failure to be
so qualified or licensed and in good standing that could not reasonably be
expected to have, individually or in the aggregate, a Company Material Adverse
Effect.

         (b) Section 4.01 of the Company Disclosure Schedule sets forth, as of
the date of this Agreement, a true and complete list of each Company Subsidiary,

         (b) Schedule 4.03 correctly and completely sets forth each agreement or
obligation of the Company and/or any Company Subsidiary to issue additional
shares of Company Common Stock after the date hereof if certain conditions are
fulfilled, and correctly and completely sets forth the maximum number of shares
of Company Common Stock issuable with respect to each business combination or
otherwise listed in Schedule 4.03 of the Company Disclosure Schedule and any
registration rights related to such shares. Such shares are hereinafter called
"Earn-out Company Shares."

         (c) Provided that the Merger becomes effective, the terms of each such
business combination require each person entitled to receive Earn-out Shares to

registration requirements of the Securities Act and applicable state securities
laws.

none of the Company Permits has been suspended or canceled nor is any such
suspension or cancellation pending or, to the knowledge of Company, threatened.

         (b) Neither Company nor any Company Subsidiary is in conflict with, or
in default or violation of, (i) any Law applicable to Company or any Company
Subsidiary or by which any property or asset of Company or any Company
Subsidiary is bound or affected or (ii) any Company Permits, except for

                                       20
<PAGE>

a Company Material Adverse Effect. Section 4.06 of the Company Disclosure

substantially all respects and (ii) did not at the time it was filed 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.
Except as disclosed in Section 4.07 of the Company Disclosure Schedule, each
form, report, statement and document referred to in clause (B) of this paragraph
was prepared in all material respects in accordance with the requirements of

most recent actuarial report or financial statement relating to such Company

knowledge of Company, any other person or entity, has any express commitment,
whether legally enforceable or not, to modify, change or terminate any Company
Benefit Plan, other than with respect to a modification, change or termination
required by ERISA or the Code.

         (b) Each Company Benefit Plan has been administered in all material
respects in accordance with its terms and all applicable laws, including ERISA
and the Code, and contributions required to be made under the terms of any of
the Company Benefit Plans as of the date of this Agreement have been timely made
or, if not yet due, have been properly reflected on the most recent consolidated
balance sheet filed or incorporated by reference in the Company Reports prior to
the date of this Agreement. With respect to the Company Benefit Plans, no event
has occurred and, to the knowledge of Company, there exists no condition or set
of circumstances in connection with which Company or any Company Subsidiary
could be subject to any liability (other than for routine benefit liabilities)
under the terms of, or with respect to, such Company Benefit Plans, ERISA, the
Code or any other applicable Law.

         (c) Company on behalf of itself and each Company ERISA Affiliate (as
defined below) hereby represents that: (i) each Company Benefit Plan which is
intended to qualify under Section 401(a), Section 401(k), Section 401(m) or
Section 4975(e)(6) of the Code has received a favorable determination letter
from the IRS as to its qualified status, and each trust established in
connection with any Company which is intended to be exempt from federal income
taxation under Section 501(a) of the Code has received an opinion letter from

that is reasonably likely to materially adversely affect the qualified status of
any such Company Benefit Plan or the exempt status of any such trust; (ii) to
Company's knowledge there has been no prohibited transaction (within the meaning
of Section 406 of ERISA or Section 4975 of the Code and other than a transaction
that is exempt under a statutory or administrative exemption) with respect to
any Company Plan that could result in liability to the Company or a Company
Subsidiary and (iii) each Company Benefit Plan can be amended, terminated or
otherwise discontinued after the

                                       23
<PAGE>

Effective Time in accordance with its terms, without liability (other than (A)
liability for ordinary administrative expenses typically incurred in a
termination event or (B) if the Company Benefit Plan is pension benefit plan
subject to Part 2 of Title I of ERISA, liability for the accrued benefits as of
the date of such termination (if and to the extent required by ERISA)) to the
extent that either there are sufficient assets set aside in a trust or insurance
contract to satisfy such liability or such liability is reflected on the most
recent consolidated balance sheet filed or incorporated by reference in the
Company Reports prior to the date of this Agreement. No suit, administrative
proceeding, action or other litigation has been brought, or to the knowledge of
Company is threatened, against or with respect to any such Company Benefit Plan,
including any audit or inquiry by the Internal Revenue Service or United States
Department of Labor (other than routine benefits claims).

         (d) No Company Benefit Plan is a multiemployer pension plan (as defined
in Section 3(37) of ERISA) or other pension plan subject to Title IV of ERISA
and neither the Company, any Company Subsidiary nor any other trade or business
(whether or not incorporated) that is under "common control" with Company or a
Company Subsidiary (within the meaning of ERISA Section 4001) or with respect to
which Company or any Company Subsidiary could otherwise incur liability under
Title IV of ERISA (a "Company ERISA Affiliate") has sponsored or contributed to
or been required to contribute to a multiemployer pension plan or other pension
plan subject to Title IV of ERISA. No material liability under Title IV of ERISA
has been incurred by Company, any Company Subsidiary or any Company ERISA
Affiliate that has not been satisfied in full, and no condition exists that
presents a material risk to Company or any Company Subsidiary of incurring or
being subject (whether primarily, jointly or secondarily) to a material
liability thereunder. None of the assets of Company or any Company Subsidiary
is, or may reasonably be expected to become, the subject of any lien arising
under ERISA or Section 412(n) of the Code.

         (e) With respect to each Benefit Plan required to be set forth in the
Disclosure Schedule that is subject to Title IV or Part 3 of Title I of ERISA or
Section 412 of the Code, (i) no reportable event (within the meaning of Section
4043 of ERISA, other than an event that is not required to be reported before or
within 30 days of such event) has occurred or is expected to occur, (ii) there
was not an accumulated funding deficiency (within the meaning of Section 302 of
ERISA or Section 412 of the Code), whether or not waived, as of the most
recently ended plan year of such Benefit Plan; and (iii) there is no "unfunded
benefit liability" (within the meaning of Section 4001(a)(18) of ERISA).

         (f) Company has delivered to Parent true, complete and correct copies
of (i) all employment agreements with officers and all consulting agreements of
Company and each Company Subsidiary, (ii) all severance plans, agreements,
programs and policies of Company and each Company Subsidiary with or relating to
their respective employees, directors or consultants, and (iii) all plans,
programs, agreements and other arrangements of Company and each Company
Subsidiary with or relating to their respective employees, directors or
consultants which contain "change of control" provisions, and all such plans,
agreements, programs, and policies are specifically identified as such on
Section 4.09 of the Company Disclosure Schedule. Except as set forth on Section
4.09 of the Company Disclosure Schedule, no payment or benefit which may be
required to be made by Company or any Company Subsidiary or which otherwise may
be required to be made under the

                                       24
<PAGE>

terms of any Company Benefit Plan or other arrangement will constitute a
parachute payment under Code Section 280(G)(1), and the consummation of the
transactions contemplated by this Agreement will not, alone or in conjunction
with any other possible event (including termination of employment), (i) entitle
any current or former employee or other service provider of Company or any
Company Subsidiary to severance benefits or any other payment, compensation or
benefit (including forgiveness of indebtedness), and the amount such severance
benefit or any other payment is indicated in Section 4.04 of the Company
Distribution Schedule except as expressly provided by this Agreement, or (ii)
accelerate the time of payment or vesting, or increase the amount of
compensation or benefit due any such employee or service provider.

         (g) Neither Company nor any Company Subsidiary is a party to, or has
any obligations under or with respect to, any collective bargaining or other
labor union contract applicable to persons employed by Company or any Company
Subsidiary and no collective bargaining agreement is being negotiated by Company
or any Company Subsidiary or any person or entity that may obligate the Company
or any Company Subsidiary thereunder. As of the date of this Agreement, there is
no labor dispute, strike, union organizing activity or work stoppage against
Company or any Company Subsidiary pending or, to the knowledge of Company,
threatened which may interfere with the respective business activities of
Company or any Company Subsidiary. As of the date of this Agreement, to the
knowledge of Company, none of Company, any Company Subsidiary, or any of their
respective representatives or employees has committed any unfair labor practice
in connection with the operation of the respective businesses of Company or any
Company Subsidiary, and there is no charge or complaint filed against Company or
any Company Subsidiary by or with the National Labor Relations Board or any
comparable Governmental Entity pending or threatened in writing.

         (h) Except as required by Law, no Company Benefit Plan provides any of
the following retiree or post-employment benefits to any person: medical,
disability or life insurance benefits. To Company's knowledge, Company and the
Company ERISA Affiliates are in compliance with (i) the requirements of the
applicable health care continuation and notice provisions of the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA") and the
regulations (including proposed regulations) thereunder and (ii) the applicable
requirements of the Health Insurance Portability and Accountability Act of 1996,
as amended, and the regulations (including the proposed regulations) thereunder.

         (i) Since November 1, 1998, neither the Company nor any Company
Subsidiary has terminated any at-will employee other than pursuant to the forms
of the notice attached hereto as Schedules 4.09(i)-1, 4.09(i)-2 or 4.09(i)-3. No
single termination of at-will employees, nor any group of terminations,
constitutes a violation of any federal or state law governing the closing of any
plant or termination or winding-up of any business.

thereunder. Except as set forth in Section 4.11 of the Company Disclosure
Schedule, the Company has not received notice of the pending or threatened
cancellation, revocation or termination of any of the Company Material
Contracts, nor are any of them aware of any facts or circumstances which could

Disclosure Schedule, to the Company's knowledge, after due inquiry, the

         Company and each Company Subsidiary is presently insured, and during
each of the past five calendar years has been insured, against such risks, as

practice, customarily be insured. The Company reasonably believes that the
policies of fire, theft, liability, medical malpractice, director and officer,
product liability and other insurance maintained with respect to the assets or
businesses of Company and Company Subsidiaries provide adequate coverage against
loss. Section 4.16 of the Company Disclosure Schedule sets forth a complete and
correct list as of the date hereof of all insurance policies maintained by
Company or the Company Subsidiaries, and Company has delivered to Parent
complete and correct copies of all such policies, together with all riders and
amendments thereto. All such policies are in full force and effect and all

         the Company's consolidated financial statements contained in the
         Company's Annual Report on Form 10-K for the fiscal year ended December

         been sold or otherwise disposed of in the ordinary course of business
         since the date of such financial statements, (ii) liens disclosed in
         the notes to such financial statements and (iii) liens arising in the
         ordinary course of business after the date of such financial
         statements. All buildings, and all fixtures, equipment and other
         property and assets that are material to its business on a consolidated
         basis, held under leases or sub-leases by Company or any Company
         Subsidiary are held under valid instruments enforceable in accordance
         with their respective terms, subject to applicable laws of bankruptcy,
         insolvency or similar laws relating to creditors' rights generally and
         to general principles of equity (whether applied in a proceeding in law
         or equity). Substantially all of Company's and the Company
         Subsidiaries' equipment in regular use has been reasonably maintained
         and is in serviceable condition, reasonable wear and tear excepted.

                  (b) Neither the Company nor any Company Subsidiary is
         obligated as a lessee (which term as used herein includes sublessee and
         similar terms) under any lease for real property, other than Company
         leases related to the Practices (as defined in Section 6.12 hereof) and
         the leases set forth in Schedule 4.17 (the "Company Leases").

Law, the execution and delivery of this Agreement, the Stockholder Agreement and
the Purchase of shares of Company Common Stock or other securities issued by the
Company or by Parent and Merger Sub, including pursuant to the Stockholder

are listed (with expiration dates, if applicable) on Section 4.23 of the Company
Disclosure. Except as set forth in Section 4.23 of the Company Disclosure
Schedule, the transactions contemplated by this Agreement will not result in a
default under or a breach or violation of, or adversely affect the rights and
benefits afforded by any licenses, franchises, permits or authorizations, except
for defaults, breaches or violations which individually or in the aggregate
could not reasonably be expected to have a Company Material Adverse Effect. All
licenses, franchises, permits and other authorizations are valid and in full
force and effect, except for those licenses, franchises, permits and other
Governmental Authorizations the failure to possess could not reasonably be
expected to have a Company Material Adverse Effect. The Company and to the
Company's Knowledge, without any independent investigation, each
Ophthalmologist/Optometrist Employee is currently in compliance therewith, and
the Company has not received any notice that any Governmental Entity is
considering challenging, revoking, canceling, restricting, conditioning or not
renewing any license, franchise, permit or other authorization, except for those
licenses, franchises, permits and other Governmental Authorizations the failure
of which to possess could not reasonably be expected to have a Company Material
Adverse Effect. Except as set forth in Section 4.23 of the Company Disclosure
Schedule, the Governmental Authorizations listed in Section 4.23 of the Company
Disclosure Schedule collectively constitute all of the Governmental
Authorizations necessary to permit the Company to lawfully conduct and operate
its business in the manner it currently conducts and operates such businesses

of the circumstances under which they were made, not misleading. Each form,
report, statement and document referred to in clause (B) of this paragraph was

immaterial liabilities or obligations incurred in the ordinary course of
business consistent with past practice since June 30, 1999 that have not had or
could not reasonably be expected to have, individually or in the aggregate, a

the "Financial Statements"). The Financial Statements have been prepared in
accordance with GAAP applied on a consistent basis throughout the periods
covered thereby (except as may be indicted in the notes thereto), present
fairly, in all material respects, the consolidated financial condition of the
Parent and the consolidated Parent Subsidiaries as of such dates and the results
of operations of the Parent and the Parent Subsidiaries for such periods
provided, however, that the Financial Statements are subject to normal and

such employee or service provider.

Parent Subsidiary. As of the date of this Agreement, to the knowledge of Parent,

         (a) Neither Parent, nor to Parent's knowledge, any of its affiliates,

of any agreement or plan to which Parent or any of its affiliates is a party or
other circumstances relating to Parent or any of its affiliates that could
reasonably be expected to prevent the Merger from so qualifying as a
reorganization under Section 368 of the Code.

         (b) Parent and each of the Parent Subsidiaries, and any consolidated,
combined, unitary or aggregated group for Tax purposes of which Parent or any
Parent Subsidiary is or has been a member, have properly completed and timely

Parent or any Parent Subsidiary is a party that may result in the payment of any
amount that would not be deductible by reason of Section 280G or Section 404 of
the Code.

         SECTION 5.11  Contracts

         (a) Section 5.11 of the Parent Disclosure Schedule sets forth a list of

                                       41
<PAGE>

Disclosure Schedule the "Parent Material Contracts"). The Parent has previously
furnished to Parent true, complete and correct copies of all written agreements,
as amended, required to be listed on Section 5.11 of the Parent Disclosure
Schedule.

         (b) The Parent Material Contracts are each in full force and effect and
are the valid and legally binding obligations of the Parent and, to the best of
Parent's knowledge, the other parties thereto, enforceable in accordance with
their respective terms, subject only to bankruptcy, insolvency or similar laws
affecting the rights of creditors generally and to general equitable principles.
The Parent has not received notice of its default under any of the Parent
Material Contracts and no event has occurred which, with the passage of time or
the giving of notice or both, would constitute a default by the Parent
thereunder. To the Parent's knowledge, none of the other parties to any of the
Parent Material Contracts is in default thereunder, nor has an event occurred
which, with the passage of time or the giving of notice or both would constitute
a default by such other party thereunder. The Parent has not received notice of
the pending or threatened cancellation, revocation or termination of any of the
Parent Material Contracts, nor are any of them aware of any facts or
circumstances which could reasonably be expected to lead to any such
cancellation, revocation or termination.

         (c) Except as otherwise indicated on Section 5.11 of the Parent
Disclosure Schedule, to the Parent's knowledge, after due inquiry, the
continuation, validity and effectiveness of the Parent Material Contracts under
the current terms thereof will in no way be affected by the consummation of the
transactions contemplated by this Agreement.

         SECTION 5.12  Litigation

         There is no suit, claim, action, proceeding or investigation pending
or, to the knowledge of Parent, threatened against Parent or any Parent
Subsidiary, and, to the knowledge of Parent, there are no existing facts or
circumstances that could reasonably be expected to result in a suit, claim,
action, proceeding or investigation. Parent is not aware of any facts or
circumstances which could reasonably be expected to result in the denial of
insurance coverage under policies issued to Parent and Parent Subsidiaries in
respect of such suits, claims, actions, proceedings and investigations. Neither
Parent nor any Parent Subsidiary is subject to any outstanding order, writ,
injunction or decree.

         SECTION 5.13  Environmental Matters

         Parent and the Parent Subsidiaries are in material compliance with all

pending, ongoing or future material obligation, cost or

                                       42
<PAGE>

liability. Neither Parent nor any Parent Subsidiary has released a Hazardous
Material at, or transported a Hazardous Material to or from, any real property
currently or formerly owned, leased or occupied by Parent or any Parent
Subsidiary, in violation of any Environmental Law.

         SECTION 5.14  Insurance

         Parent and each Parent Subsidiary is presently insured, and during each
of the past five calendar years has been insured, against such risks, as
companies engaged in a similar business would, in accordance with good business
practice, customarily be insured. The Parent reasonably believes that the
policies of fire, theft, liability, medical malpractice, director and officer,
product liability and other insurance maintained with respect to the assets or
businesses of Parent and Parent Subsidiaries provide, adequate coverage against
loss. Parent has made available to Company a complete and correct list as of the
date hereof of all insurance policies maintained by Parent or the Parent
Subsidiaries, and has made available to Company complete and correct copies of
all such policies, together with all riders and amendments thereto. All such
policies are in full force and effect and all premiums due thereon have been
paid to the date hereof. Parent and the Parent Subsidiaries have complied in all
material respects with the terms of such policies.

         SECTION 5.15  Properties

         Parent and the Parent Subsidiaries have good title, free and clear of
all material mortgages, liens, pledges, charges or other encumbrances to all
their material tangible properties and material assets, real, personal or mixed,
reflected in the Parent's consolidated financial statements for the quarterly
period ended September 30, 1999, as being owned by Parent and the Parent
Subsidiaries as of the date thereof, other than (i) any properties or assets
that have been sold or otherwise disposed of in the ordinary course of business
since the date of such financial statements, (ii) liens disclosed in the notes
to such financial statements and (iii) liens arising in the ordinary course of
business after the date of such financial statements or disclosed in Section
5.15 of the Parent Disclosure Schedule. All buildings, and all fixtures,
equipment and other property and assets that are material to its business on a
consolidated basis, held under leases or sub-leases by Parent or any Parent
Subsidiary are held under valid instruments enforceable in accordance with their
respective terms, subject to applicable laws of bankruptcy, insolvency or
similar laws relating to creditors' rights generally and to general principles
of equity (whether applied in a proceeding in law or equity). Substantially all
of Parent's and the Parent Subsidiaries' equipment in regular use has been
reasonably maintained and is in serviceable condition, reasonable wear and tear
excepted.

         SECTION 5.16  Opinion of Financial Advisor

         Legg Mason Wood Walker, Incorporated ("Legg Mason") has delivered to
the board of directors of Parent its written opinion to the effect that, as of
the date hereof, the Exchange Ratio is fair to the holders of shares of Parent
Common Stock from a financial point of view (the "Legg Mason Fairness Opinion").

         SECTION 5.17  Brokers

         Except as set forth on Section 5.17 of Parent Disclosure Schedule, no
broker, finder or

                                       44
<PAGE>

investment banker (other than Legg Mason and J.P. Morgan Securities, Inc.) is
entitled to any brokerage, finder's or other fee or commission in connection
with the Merger based upon arrangements made by or on behalf of Parent. Parent
has heretofore made available to Parent true, complete and correct copies of all
agreements between Parent, on the one hand, and Legg Mason and/or J.P. Morgan
Securities, Inc., on the other hand, pursuant to which such firms would be
entitled to any payment relating to the Merger.

         SECTION 5.18  No Interested Shareholders

         To Parent's knowledge, neither the Company nor any "affiliate" or
"associate" of the Company is an "interested shareholder" as those terms are
defined in 607.0901 of the FBCA.

         SECTION 5.19  Governmental Authorizations

         The Parent and, to the Parent's knowledge, without any independent
investigation, each Ophthalmologist/Optometrist Employee, possesses all
necessary licenses, franchises, permits and other governmental authorizations
(collectively, "Governmental Authorizations"), including, but not limited to,
all licenses, franchises, permits and authorizations for the conduct of the
Parent's business as now conducted, except for those licenses, franchises,
permits and other governmental authorizations the failure of which to possess
could not reasonably be expected to have a Parent Material Adverse Effect.
Except as set forth in Section 5.19 of the Parent Disclosure Schedule, the
transactions contemplated by this Agreement will not result in a default under
or a breach or violation of, or adversely affect the rights and benefits
afforded by any material licenses, franchises, permits or authorizations, except
for those licenses, franchises, permits and other governmental authorizations
the failure of which to possess could not reasonably be expected to have a
Parent Material Adverse Effect . All such licenses, franchises, permits and
other authorizations are valid and in full force and effect, except for those
licenses, franchises, permits and other governmental authorizations the failure
of which to possess could not reasonably be expected to have a Parent Material
Adverse Effect. The Parent and to the Parent's knowledge, without any
independent investigation, each Ophthalmologist/Optometrist Employee is
currently in compliance therewith, and the Parent has not received any notice
that any Governmental Entity is considering challenging, revoking, canceling,
restricting, conditioning or not renewing any material license, franchise,
permit or other authorization except for those licenses, franchises, permits and
other governmental authorizations the failure of which to possess could not
reasonably be expected to have a Parent Material Adverse Effect.

         SECTION 5.20 Intellectual Property.

         The Parent and the Parent Subsidiaries have ownership of or rights to
use each patent, patent application, copyright (whether or not registered),
copyright application, trademark (whether or not registered), trademark
application, trade name, service mark, and other trade secret or proprietary
intellectual property owned by or used in and material to the business of the
Parent and the Parent Subsidiaries, taken as a whole (collectively, a "Parent
Intellectual Property"). The Parent has been provided with a list of all
patents, trademarks and copyrights and applications therefor owned by or

                                       45
<PAGE>

licensed to the Parent or any Subsidiary that are material to the conduct of the
business of the Parent and the Parent Subsidiaries, taken as a whole, as now
operated. To the Parent's Knowledge, none of the previous or current
development, manufacture, marketing or distribution of products or services of
or by the Parent or any Parent Subsidiary infringes the right of any other
person, except for any such infringements that, in the aggregate, have not
resulted in, and could not reasonably be expected to result in, a Parent
Material Adverse Effect. To the Parent's Knowledge, without any independent
investigation, no other person is infringing the rights of the Parent or any
Parent Subsidiary in any such Parent Intellectual Property, except for any such
infringements that, in the aggregate, have not resulted in, and could not
reasonably be expected to result in, a Parent Material Adverse Effect. To the
best of Parent's knowledge, Parent's material software and hardware are year
2000 compliant, except to the extent noncompliance should not or could not
reasonably be expected to cause a Parent Material Adverse Effect.

         (a) Except as provided in Section 6.04(b) below, Company shall not,
directly or indirectly, and shall cause its Representatives not to, directly or
indirectly, solicit, initiate or encourage (including by way of furnishing
nonpublic information), any inquiries or the making of any proposal or offer
(including, without limitation, any proposal or offer to its stockholders) that
constitutes, or may reasonably be expected to lead to, any Competing
Transaction, or enter into or maintain or continue discussions or negotiate with
any person in furtherance of such inquiries or to obtain a Competing
Transaction, or agree to or endorse any Competing Transaction, or authorize or
permit any of Company's Representatives or subsidiaries, or any Representative
retained by Company's subsidiaries, to take any such action; provided, however,
that nothing contained in this Section 6.04(a) shall prohibit the board of
directors of Company (i) from complying with Rule 14d-9 or 14e-2(a) promulgated
under the Exchange Act with regard to a tender or exchange offer not made in
violation of this Section 6.04(a) or (ii) prior to receipt of the approval by
the stockholders of Company of this Agreement and the Merger from providing
information (subject to a confidentiality agreement at least as restrictive as
the Confidentiality Agreement) in connection with, and negotiating, another
unsolicited, bona fide written proposal regarding a Competing Transaction that
(x) Company's board of directors shall have concluded in good faith, after
considering applicable state law, on the basis of the advice of independent
outside counsel that such action is necessary to prevent Company's board of
directors from violating its fiduciary duties to Company's stockholders under
applicable law, and with respect to which Company's board of directors shall
have determined (based upon the advice of Company's independent financial
advisors) in the proper exercise of its fiduciary duties to Company's
stockholders that the acquiring party is capable of consummating such Competing
Transaction on the terms proposed, and (y) Company's board of directors shall
have determined in the proper exercise of its fiduciary duties to Company's
stockholders that such Competing Transaction provides greater value to the
stockholders of Company than the Merger (based upon the written opinion of
Company's independent financial advisors that such Competing Transaction is
superior from a financial point of view) (any such Competing Transaction being
referred to herein as a "Superior Proposal"). Any violation of the restrictions
set forth in this Section 6.04(a) by any Representative of Company or any of its
Subsidiaries, whether or not such Person is purporting to act on behalf of
Company or otherwise, shall be deemed to be a breach of this Section 6.04(a) by
Company. Company shall notify Parent promptly if any proposal or offer, or any
inquiry or contact with any person with respect thereto, regarding a Competing
Transaction is made, such notice to include the identity of the person making
such proposal, offer, inquiry or contact, and the terms of such Competing
Transaction, and shall keep Parent apprised, on a current basis, no later than
24 hours after any change or modification of any such Competing Transaction, of
the status of such Competing Transaction and of any modifications to the terms
thereof. Company immediately shall cease and cause to be terminated all existing
discussions or negotiations with any parties conducted heretofore with respect
to a Competing Transaction. Company shall not release any third party from, or
waive any provision of, any confidentiality or standstill agreement to which it
is a party.

         (b) Except as permitted by this Section 6.04(b), the Company's Board of
Directors shall not (i) withdraw, modify or change its approval or
recommendation of this Agreement, or propose publicly to withdraw, modify or
change the Merger or any of the transactions contemplated hereby, (ii) approve
or recommend or publicly propose to approve or recommend a Competing
Transaction, (iii) cause the Company to enter into any letter agreement, letter
of intent, agreement in principle or definitive agreement or similar agreement
providing for a Competing Transaction, or (iv) resolve to do any of the
foregoing, unless prior to the Company Stockholders' Meeting, the Company
receives an unsolicited proposal for a Competing Transaction and the Board of
Directors or the Company determines reasonably and in good faith, after due
investigation, that (a) such proposal is a Superior Proposal based upon the
written opinion of the Company's independent financial advisors that such
Competing Transaction is superior from a financial point of view, (b) the Person
making such Superior Proposal is reasonably capable of consummating such
Superior Proposal in a timely fashion and (c) based upon the advice of
independent outside counsel, the failure of the Board of Directors of the
Company to withdraw or modify its approval or recommendation of this Agreement
or the Merger, or approve or recommend such Superior Proposal, would be
inconsistent with its fiduciary duties under applicable law. In such case, the
Board may withdraw or modify its recommendation, and approve and recommend such
Superior Proposal, provided the Board of Directors of the Company (i) at least
five (5) Business Days prior to taking such action, provides to Parent written
notice of the Company's intention to accept the Superior Proposal, (ii) during
such period, gives parent a reasonable opportunity to propose modifications to
the Merger Consideration and negotiates such modifications in good faith with
the objective of allowing Parent to match the Superior Proposal and (iii) at the
end of such period, (A) reasonably and in good faith continues to believe that
the other proposal is a Superior Proposal, (B) simultaneously terminates this
Agreement, (C) concurrently causes the Company to enter into a definitive
acquisition agreement with respect to such Superior Proposal and (D)
concurrently pays to Parent the Termination Fee and Parent's Expenses as
provided in Section 9.05. Nothing contained in this Section 6.04(b) shall
prohibit the Company from taking and disclosing to its stockholders a position
contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act;
provided that the Company does not withdraw or modify its position with respect
to the Merger or approve or recommend a proposal for a Competing Transaction
except as provided in this Section 6.04(b).

         SECTION 6.05  Tax-Free Transaction

         From and after the date of this Agreement, each party hereto shall use
all reasonable efforts to cause the Merger to qualify, and shall not knowingly
take any actions or cause any actions to be taken which could reasonably be
expected to prevent the Merger from qualifying as a "reorganization" under
Section 368(a) of the Code.

         SECTION 6.06  Control of Operations

         Nothing contained in this Agreement shall give Parent, directly or
indirectly, the right to control or direct the operations of Company and the
Company Subsidiaries prior to the Effective Time. Prior to the Effective Time,
Company shall exercise, consistent with the terms and conditions of this
Agreement, complete control and supervision over its operations.

         SECTION 6.07  Further Action; Consents; Filings

         (a) Upon the terms and subject to the conditions hereof, each of the
parties hereto shall use all reasonable efforts to (i) take, or cause to be
taken, all appropriate action, and do, or cause to be done, all things
necessary, proper or advisable under applicable Law or otherwise to consummate
and make effective the Merger, (ii) obtain from any Governmental Entity any
consents, licenses, permits, waivers, approvals, authorizations or orders
required to be obtained or made by Parent or Company or any of their respective
subsidiaries in connection with the authorization, execution and delivery of
this Agreement and the consummation of the Merger and (iii) make all necessary
filings, and thereafter make any other required or appropriate submissions, with
respect to this Agreement and the Merger required under (A) the rules and
regulations of the AMEX or the NNM, as the case may be, (B) the Securities Act,
the Exchange Act and any other applicable Federal or state securities Laws, (C)
the HSR Act, if any, and (D) any other applicable Law. The parties hereto shall
cooperate and consult with each other in connection with the making of all such
filings, including by providing copies of all such documents to the nonfiling
parties and their advisors prior to filing, and none of the parties shall file
any such document if any of the other parties shall have reasonably objected to
the filing of such document. No party shall consent to any voluntary extension
of any statutory deadline or waiting period or to any voluntary delay of the
consummation of the Merger at the behest of any Governmental Entity without the
consent and agreement of the other parties hereto, which consent shall not be
unreasonably withheld or delayed. The Parent shall not be required to divest
itself or the Company of any assets or business in order to obtain approval in
connection with the HSR Act or otherwise.

         (b) Each of Company and Parent will give (or will cause their
respective subsidiaries to give) any notices to third persons, and use, and
cause their respective subsidiaries to use, reasonable efforts to obtain any
consents from third persons necessary, proper or advisable (as determined in
good faith by Parent with respect to such notices or consents to be delivered or
obtained by Company) to consummate the transactions contemplated by this
Agreement.

         SECTION 6.08  Additional Reports

         Company and Parent shall each furnish to the other copies of any
reports of the type referred to in Sections 4.07 and 5.06, which it files with
the SEC on or after the date hereof, and Company and Parent, as the case may be,
covenant and warrant that as of the respective dates thereof, such reports will
not contain any untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in light of the circumstances under which they were made, not misleading. Any
unaudited consolidated interim financial statements included in such reports
(including any related notes and schedules) will fairly present in all material
respects the financial position of Company and its consolidated subsidiaries or
Parent and its consolidated subsidiaries, as the case may be, as of the dates
thereof and the results of operations and changes in financial position or other
information including therein for the periods or as of the date then ended
(subject, where appropriate, to normal year-end adjustments), in each case in
accordance

                                       52
<PAGE>

with past practice and U.S. GAAP consistently applied during the periods
involved (except as otherwise disclosed in the notes thereto).

         SECTION 6.09  Conduct of Business by Parent

         During the period from the date of this Agreement and continuing until
the earlier of the termination of this Agreement pursuant to its terms or the
Effective Time, Parent shall not knowingly take any action a principal purpose
of which is, and the reasonably likely result of which would be, a material
delay in or interference with the consummation of the Merger. Neither Parent nor
any Parent Subsidiary shall, between the date of this Agreement and the
Effective Time, directly or indirectly, do, or agree to do, any of the following
without the prior written consent of Company, except as a result of entering

         (i) more than outstanding 20% of the shares of capital stock of Parent
         or any shares of capital stock of a Parent Subsidiary of any class, or
         securities convertible into or exchangeable or exercisable for any
         shares of such capital stock, or any options, warrants or other rights
         of any kind to acquire more than 20% of the outstanding shares of such
         capital stock or any other ownership interest (including, without
         limitation, any phantom interest), of Parent or any Parent Subsidiary,
         other than the issuance of shares of Parent common stock pursuant to
         the exercise of stock options granted pursuant to the Parent Stock
         Plans, or (ii) any material property or material assets of Parent or

         merger, consolidation, or acquisition of stock or assets) of any
         interest in any corporation, partnership, other business organization
         or person or any division thereof which would be considered a
         "Significant Subsidiary" of the Parent (after taking into effect the
         Merger); (ii) except in connection with an acquisition permitted
         pursuant to the foregoing clause (i), incur any material indebtedness

         Subsidiaries) for borrowed money or make any loans or advances,
         material to the business, assets, liabilities, financial condition or
         results of operations of Parent and the Parent Subsidiaries, taken as a
         whole, other than borrowings under the Parent's credit facility for use
         in operating the business; or (iii) enter into or amend any contract,
         agreement, commitment or arrangement in which the Parent is obligated
         to perform and, if fully performed, would not be permitted under this
         Section 6.09(c);

                                       53

                  (d) declare, set aside, make or pay any dividend or other
         distribution, payable in cash, stock, property or otherwise, with

         stock;

         Parent Stock Plans or other options and warrants or take any action to
         reprice any such options and warrants;

                  (g) authorize or enter into any formal or informal agreement
         or otherwise make any commitment to do any of the foregoing or take any
         action which would result in any of the conditions to the merger set
         forth herein not being satisfied.

                  (h) take any action resulting in the delisting of Parent from
         the Amex; and

after the execution of this Agreement, which provides, among other things, that
each of the parties to the Existing Credit Agreement agrees to proceed in good

third party beneficiary to the Letter of Intent, and the Company shall use its
commercially reasonable efforts to finalize the amendment in accordance with the
Letter of Intent. The Parent will use commercially reasonable efforts to enter

Practices and cause or have an agreement which will cause all of such Practices
to assume all liabilities and obligations relating to such Practices

agreement substantially in the form of Annex D hereto from (i) each person
identified in Section 4.18 of the Company Disclosure Schedule within 15 days
following the execution and delivery of this Agreement and (ii) from any person
who, to the knowledge of Company, may be deemed to have become an affiliate of
Company after the date of this Agreement and prior to the Effective Time as soon
as practicable after attaining such status. The foregoing notwithstanding,
Parent shall be entitled to place legends as specified in the Affiliate
Agreement on the certificates evidencing any of the Parent Common Stock to be
received by (i) any affiliate of Company or (ii) any person Parent reasonably
identifies (by written notice to Company) as being a person who is an
"affiliate" within the meaning of Rule 145 promulgated under the Securities Act,
and to issue appropriate stop transfer instructions to the transfer agent for
such Parent Common Stock, consistent with the terms of the Affiliate Agreement,
regardless of whether such person has executed Affiliate Agreement and
regardless of whether such person's name and address appear on Section 4.18 of
the Company Disclosure Schedule.

         SECTION 7.04  Directors' and Officers' Indemnification and Insurance

         (a) Parent and the Merger Sub agree that all rights to indemnification,
advancement of expenses, exculpation, limitation of liability and any and all
similar rights now existing in favor of each present and former director,
officer, employee and agent of Company and each Company Subsidiary
(collectively, the "Indemnified Parties") as provided in the Company's present
charter or by-laws in effect on the date hereof, shall survive the Merger and
shall continue in full force and effect for a period of five years from the
Effective Time, which provisions shall not be amended, repealed or otherwise
modified for a period of five years from the Effective Time in any manner that
would affect adversely the rights thereunder of individuals who at any time
prior to the Effective Time were directors, officers, employees or agents of the
Company, unless such modification shall be required by law, and Parent agrees to
cause the Surviving Corporation to comply with its obligations thereunder;
provided, however, that in the event any claim or claims are asserted or made
within such five-year period, all rights to indemnification in respect to any
such claim or claims shall continue until the disposition of any and all such
claims.

         (b) In the event the Company or the Surviving Corporation or any of
their respective successors or assigns (i) consolidates with or merges into any
other person and shall not be the continuing or Surviving Corporation or entity
of such consolidation or merger or (ii) transfers a material amount of its
properties and assets to any person in a single transaction or a series of
transactions, then, and in each such case, Parent will make or cause to be made
proper provision so that the successors and assigns of the Company or the
Surviving Corporation, as the case may be, assume the indemnification
obligations described herein for the benefit of the Indemnified Parties as a
condition to such merger, consolidation or transfer becoming effective.

         (c) The provisions of this Section 7.04 are (i) intended to be for the
benefit of, and will be enforceable by, each of the Indemnified Parties and (ii)
in addition to, and not in substitution for, any

                                       59
<PAGE>

other rights to indemnification or contribution that any such person may have by
contract or otherwise.

         (d) Parent agrees, as soon as practicable after the Effective Time, to
cause the Surviving Corporation to use commercially reasonable efforts to
purchase tail coverage, if available, for the directors' and officers' liability
insurance policies currently maintained by Company covering a period of five
years after the Effective Time; provided, however, that in no event shall Parent
be required to expend in excess of $250,000 on the premium for such five year
tail coverage. To the extent that the premium for such tail coverage exceeds
$250,000, Surviving Corporation shall pay such additional premium amount (the
"Additional Premium Amount"). In the event that such tail coverage is not
available, the Surviving Corporation shall have no obligation to purchase such
tail coverage, but shall maintain in effect the Company's directors' and
officers' liability insurance policies in effect as of the date hereof or, if
not available, directors' and officers' liability insurance policies covering
the directors and officers of the Company (and their respective heirs and
executors, if such coverage may be obtained at no additional cost), with
coverages and other terms substantially as favorable to such directors and
officers as is currently in effect; provided, however, that in no event shall
the Surviving Corporation be required to expend in any one year in excess of
150% of the annual premium currently paid by Company for such coverage, which
current premium amount is set forth in Section 7.04 of the Company Disclosure
Schedule, and if the premium for such coverage exceeds such amount, Parent shall
purchase a policy with the greatest coverage available for such 150% of the
annual premium; and provided, further, that the cumulative annual premiums to be
paid for such policies over a five-year period shall be projected by Parent's
insurance broker in good faith on or prior to the Exchange Ratio Adjustment Date
(the "Projected Cumulative Amount"). (The amount by which the Projected
Cumulative Amount exceeds $250,000 is herein referred to as the "Excess
Projected Cumulative Amount".)

         SECTION 7.05  No Shelf Registration

         Parent shall not be required to amend or maintain the effectiveness of
the Registration Statement for the purpose of permitting resale of the shares of
Parent Common Stock received pursuant hereto by the persons who may be deemed to
be "affiliates" of Company within the meaning of Rule 145 promulgated under the
Securities Act.

         SECTION 7.06  Public Announcements

         The initial press release concerning the Merger shall be a joint press
release and, thereafter, Parent and Company shall consult with each other before
issuing any press release or otherwise making any public statements with respect
to this Agreement or the Merger and shall not issue any such press release or
make any such public statement without the prior written approval of the other,
except to the extent required by applicable Law or the requirements of the rules
and regulations of the AMEX and the NNM, in which case the issuing party shall
use all reasonable efforts to consult with the other party before issuing any
such release or making any such public statement.

         SECTION 7.07 AMEX Listing

                                       60

         SECTION 7.08  Blue Sky

         Parent shall use all reasonable efforts to obtain prior to the
Effective Time all necessary permits and approvals required under Blue Sky Laws
to permit the distribution of the shares of Parent Common Stock to be issued in
accordance with the provisions of this Agreement.

         SECTION 7.09 Acquisition of Company Capital Stock

         Prior to the Effective Time, neither Parent, nor any of Parent
Subsidiaries or Affiliates will, nor will they assist or encourage others to,
directly or indirectly, acquire or attempt to acquire ownership of more than
five percent (5%) of the Company's capital stock.

         Prior to the Effective Time, neither Company, nor any of Company

         prohibiting its consummation;

                                       61
<PAGE>

                  (b) by either Parent or Company, if the Effective Time shall

         the right to terminate this Agreement under this Section 9.01(b) shall
         not be available to any party whose failure to fulfill any obligation
         under this Agreement shall have principally caused, or resulted in, the
         failure of the Effective Time to occur on or before such date;

                  (c) by either Parent or Company, if any Governmental Order,
         writ, injunction or decree preventing the consummation of the Merger
         shall have been entered by any court of competent jurisdiction and
         shall have become final and nonappealable;

                  (d) by Parent, if (i) the board of directors of Company
         withdraws, modifies or changes its recommendation of this Agreement or

         directors of Company resolves to take any of the actions described
         above;

         shall fail to receive the requisite votes for approval at the Company
         Stockholders' Meeting or any adjournment or postponement thereof or
         (ii) if the Share Issuance shall fail to receive the requisite votes
         for approval at the Parent Shareholders' Meeting or any adjournment or
         postponement thereof;

                  (f) by Parent, upon a material breach of any representation or
         warranty on the part of Company set forth in this Agreement, upon a
         material breach of any covenant or agreement on the part of the Company
         set forth in this Agreement or if any material representation or
         warranty of Company shall have become untrue, incomplete or incorrect
         in any material respect, in any case such that the conditions set forth
         in Section 8.03 would not be satisfied (a "Terminating Company
         Breach"); provided, however, that if such Terminating Company Breach is
         curable by Company through the exercise of its reasonable efforts
         within 20 days and for so long as Company continues to exercise such
         reasonable efforts, Parent may not terminate this Agreement under this
         Section 9.01(f) during such 20

                                       65
<PAGE>

         day period; and provided, further that the preceding proviso shall not
         in any event be deemed to extend any date set forth in paragraph (b) of
         this Section 9.01; or

                  (g) by Company, upon material breach of any representation,
         warranty, covenant or agreement on the part of Parent set forth in this
         Agreement, or if any material representation or warranty of Parent
         shall have become untrue, incomplete or incorrect in any material
         respect, in either case such that the conditions set forth in Section
         8.02 would not be satisfied (a "Terminating Parent Breach"); provided,
         however, that if such Terminating Parent Breach is curable by Parent
         through the exercise of its reasonable efforts within 20 days and for
         so long as Parent continues to exercise such reasonable efforts,
         Company may not terminate this Agreement under this Section 9.01(g)
         during such 20 day period; and provided, further that the preceding
         proviso shall not in any event be deemed to extend any date set forth
         in paragraph (b) of this Section 9.01.

                  (h) by a party, if on or before the applicable date set forth
         in Article VIII , any condition set forth in Article VIII which is
         required to be met on or before such date has not been so met by the
         other party; provided, however, that if such failed condition is
         curable by the other party through the exercise of its reasonable
         efforts within 20 days and for so long as such other party continues to
         exercise such reasonable efforts, the terminating party may not
         terminate this Agreement under this Section 9.01(h); and provided,
         further that the preceding proviso shall not in any event be deemed to
         extend any date set forth in paragraph (b) of this Section 9.01;

                  (i) by the Company, pursuant to Section 6.04, in the event the
         Company has complied with all the provisions of Section 6.04 and has
         determined to accept a Superior Proposal; provided that the Company
         shall have provided Parent with one Business Day's prior written notice
         of the Company's decision to so terminate (the "Company Termination
         Notice"). The Company Termination Notice shall indicate in reasonable
         detail the terms and conditions of such Superior Proposal, including,
         without limitation, the amount and form of the proposed consideration
         and whether such Superior Proposal is subject to any material
         conditions.

         In the event either party shall terminate this Agreement pursuant to
         Section 9.01, neither Parent nor any of Parent's Subsidiaries will, nor
         will they assist or encourage others to, directly or indirectly, for a
         period of two (2) years after termination of this Agreement, acquire or
         attempt to acquire ownership or more than five percent (5%) of the
         Company's capital stock.

         The right of any party hereto to terminate this Agreement pursuant to
this Section 9.01 will remain operative and in full force and effect regardless
of any investigation made by or on behalf of any party hereto, any person
controlling any such party or any of their respective officers, directors,
representatives or agents, whether prior to or after the execution of this
Agreement.

         SECTION 9.02  Effect of Termination

                                       66
<PAGE>

         Except as provided in Section 9.05, in the event of termination of this
Agreement pursuant to Section 9.01 or otherwise, this Agreement shall forthwith
become void, there shall be no liability under this Agreement or otherwise on
the part of any party hereto or any of its affiliates or any of its or their
officers or directors, and all rights and obligations of each party hereto shall
cease. No termination of this Agreement shall affect the obligation of the
parties contained in the Confidentiality Agreements, which shall survive

the Company assumed or offered to be assumed, as the case may be, in this or
such Competing Transaction, as the case may be.

         (c) In the event that Parent shall terminate this Agreement pursuant to

Agreement, Company shall enter into a definitive agreement with respect to any
Competing Transaction (other than a Competing Transaction solely described in

consummation of such Competing Transaction (other than a Competing Transaction
solely described in clause (v) of the definition of such term), the Company
shall pay to Parent an amount in cash equal to one-half of the Termination Fee
unless Company did not have Knowledge at the time that this Agreement was
entered into that such representation or warranty was incorrect or incomplete,
in which case Company shall not be obligated to such portion of the Termination
Fee, but shall nonetheless be obligated to pay Parent's Expenses as set forth
above.

         (d) In the event that Parent shall terminate this Agreement pursuant to
clause (ii) of Section 9.01(f) (other than in connection with a breach of
Section 6.04 or Section 6.01(y) hereof, which are provided for below), then
Company shall promptly reimburse Parent for Parent's Expenses, and if, within

definitive agreement with respect to any Competing Transaction (other than a
Competing Transaction solely described in clause (v) of the definition of such

cash the Termination Fee.

in this Article IX above are reasonable, are an integral part of the transaction
contemplated by this Agreement, and are the sole and exclusive remedies in law
or in equity for a termination or breach of this Agreement or otherwise in
connection with the transactions contemplated by this Agreement. The payments
provided for in this Section 9.05 are intended to establish liquidated damages

9.04(c), (d) and/or (e) hereof, such dispute shall be submitted for arbitration
to the American Arbitration Association ("AAA") in New York City in accordance
with the Commercial Rules of the American Arbitration Association, provided;
however, that such arbitrators shall apply the Delaware General Corporation Law
and applicable case law thereunder to the resolution of the dispute. The
decision of the AAA shall be final and binding upon the parties, and shall be
enforceable in any court of competent jurisdiction. Nothing in this provision
shall be construed to prohibit any party hereto from seeking interim equitable
relief in a court of competent jurisdiction pending submission of said dispute
to arbitration hereunder.
