ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         The Acquisitions. On December 30, 1997, Vision Twenty-One, Inc. (the
"Company") closed, effective December 1, 1997, the acquisition of one-hundred
percent (100%) of the outstanding stock of LSI Acquisition, Inc. ("LSI") and MEC
Health Care, Inc., ("MEC"), both of which were wholly-owned subsidiaries of
LaserSight, Inc. (the "Acquisitions"). As consideration for the Acquisitions,
LaserSight, Inc. was paid aggregate consideration of approximately $13.0 million
consisting of $6.5 million in cash and 812,500 shares of Company common stock.
The consideration is subject to certain adjustments. The cash portion of the
consideration paid by the Company for the Acquisition was financed through a
letter amendment to the Company's credit facility with Prudential Securities
Credit Corporation. In addition, LaserSight, Inc. and the Company entered into a
Stock Distribution Agreement for the liquidation of the shares of Company Common
stock received by LaserSight, Inc. by May 29, 1998 through, at the Company's 
option, the filing of a shelf registration statement, a private placement, a 
direct redemption by the Company, or other method acceptable to the Company 
and LaserSight, Inc. Under the Stock Distribution Agreement, LaserSight, Inc.
is entitled to receive a minimum of $6.5 million and a maximum of $7.475
million from the liquidation subject to certain post-closing adjustments.

         LSI has a twenty-five year service agreement with Northern N.J. Eye
Institute, an ophthalmology practice located in South Orange, New Jersey, with
four locations including an ambulatory surgery center. The LSI acquisition
allows the Company to further expand its Local Area Delivery Systems (LADS) in
the state of New Jersey. The estimated clinic revenues of N.J. Eye Institute
were $4.0 million for the year ended December 31, 1997.

         MEC is a managed care company located in Baltimore, Maryland. MEC
operates an Administrative Service Center and holds eleven managed eye care
contracts covering over 650,000 capitated optometry and ophthalmology lives
which are serviced through a provider panel consisting of over 400 contracted
eye care physicians, principally located in the greater Baltimore, Washington,
D.C. and Virginia metropolitan areas. With the substantial increase in covered
lives, the MEC acquisition continues the Company's strategy of capturing managed
care business. The estimated revenues from MEC were $8.7 million for the year
ended December 31, 1997.

         The Acquisitions will be accounted for as a "purchase" for financial
reporting purposes.

that the Purchaser believes that the Proposed Stock Purchase Consideration
Adjustment has not been prepared on the basis set forth above or otherwise
contests any item set forth therein, the Purchaser shall, on or before the last
day of such 30 day period, so object to Stockholder and Escrow Agent in writing,
setting forth a specific description of the nature of the objection and the
corresponding adjustments the Purchaser believes should be made. If no objection
is received by Stockholder on or before the last day of such 30 day period, then
the Proposed Stock Purchase Consideration Adjustment delivered by Stockholder
shall be final. If an objection has been made and Stockholder and Purchaser are
unable to resolve all of their disagreements with respect to the proposed
adjustments within 15 days following the delivery of the Purchaser's objection,
the dispute shall be submitted to arbitration as provided in Section 17.1 except
that the arbitrator shall be instructed to deliver his determination of the
number of Adjustment Shares to be delivered to the Stockholder to the parties

other way to provide funds in respect of or to guarantee or assume in any
manner, any debt, obligation or dividend of any person, corporation,

Governmental Entity, including, without limitation, applicable state
corporation, insurance and health regulatory authorities with respect to the
Purchaser is pending, or threatened, nor has any Governmental Entity, including,
without limitation, applicable state corporation, insurance and health
regulatory authority indicated an intention to conduct the same, other than

investment in the Securities and is able to sustain a complete loss of such
investment.

                           e.       The Stockholder confirms that it has had the
opportunity to ask questions of and receive answers from Purchaser concerning

harmless from and against all Damages asserted against or incurred by them
arising out of or resulting from:

                           a.       a breach by Purchaser of any representation,

required to be stated therein or necessary to make the statements therein not

                  14.3.    Conditions of Indemnification. All claims for
indemnification under this Agreement shall be asserted and resolved as follows:

                           a.       A party claiming indemnification under this
Agreement (an "Indemnified Party") shall promptly (and, in any event, at least
ten (10) days prior to the due date for any responsive pleadings, filings or
other documents) (i) notify the party from whom indemnification is sought (the
"Indemnifying Party") of any third-party claim or claims asserted against the
Indemnified Party ("Third Party Claim") that could give rise to a right of
indemnification under this Agreement and (ii) transmit to the Indemnifying Party
a written notice ("Claim Notice") describing in reasonable detail the nature of
the Third Party Claim, a copy of all papers served with respect to such claim
(if any), an estimate of the amount of damages attributable to the Third Party
Claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. Except as set forth in Section 14.6, the failure to promptly
deliver a Claim Notice shall not relieve the Indemnifying Party of its
obligations to the Indemnified Party with respect to the related Third Party
Claim except to the extent that the resulting delay is materially prejudicial to
the defense of such claim. Within thirty (30) days after receipt of any Claim
Notice (the "Election Period"), the Indemnifying Party shall notify the
Indemnified Party (i) whether the Indemnifying Party disputes its potential
liability to the Indemnified Party under this Article 16 with respect to such
Third Party Claim and (ii) whether the Indemnifying Party desires, at the sole
cost and expense of the Indemnifying Party, to defend the Indemnified Party
against such Third Party Claim.

                  If the Indemnifying Party notifies the Indemnified Party
within the Election Period that the Indemnifying Party elects to assume the
defense of the Third Party Claim, then the Indemnifying Party shall have the
right to defend, at its sole cost and expense, such Third Party Claim by all
appropriate proceedings, which proceedings



                                      -49-
<PAGE>   50

shall be prosecuted diligently by the Indemnifying Party to a final conclusion
or settled at the discretion of the Indemnifying Party in accordance with this
Section 14.3. The Indemnifying Party shall have full control of such defense and
proceedings, including any compromise or settlement thereof. The Indemnified
Party is hereby authorized, at the sole cost and expense of the Indemnifying
Party (but only if the Indemnified Party is entitled to indemnification
hereunder), to file, during the Election Period, any motion, answer or other
pleadings that the Indemnified Party shall deem necessary or appropriate to
protect its interests or those of the Indemnifying Party and not prejudicial to
the Indemnifying Party (it being understood and agreed that if an Indemnified
Party takes any such action that is prejudicial and causes a final adjudication
that is adverse to the Indemnifying Party, the Indemnifying Party shall be
relieved of its obligations hereunder with respect to such Third Party Claim).
If requested by the Indemnifying Party, the Indemnified Party agrees, at the
sole cost and expense of the Indemnifying Party, to cooperate with the
Indemnifying Party and its counsel in contesting any Third Party Claim that the
Indemnifying Party elects to contest, including, without limitation, the making
of any related counterclaim against the person asserting the Third Party Claim
or any cross-complaint against any person. The Indemnified Party may participate
in, but not control, any defense or settlement of any Third Party Claim
controlled by the Indemnifying Party pursuant to Section 14.3(b) and shall bear
its own costs and expenses with respect to such participation; provided,
however, that if the named parties to any such action (including any impleaded
parties) include both the Indemnifying Party and the Indemnified Party, and the
Indemnified Party has been advised by counsel that there may be one or more
legal defenses available to it that are different from or additional to those
available to the Indemnifying Party, then the Indemnified Party may employ
separate counsel at the expense of the Indemnifying Party, and upon written
notification thereof, the Indemnifying Party shall not have the right to assume
the defense of such action on behalf of the Indemnified Party; provided further
that the Indemnifying Party shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
reasonable fees and expenses of more than one separate firm of attorneys at any
time for the Indemnified Party, which firm shall be designated in writing by the
Indemnified Party.

                  b.       If the Indemnifying Party fails to notify the
Indemnified Party within the Election Period that the Indemnifying Party elects
to defend the Indemnified Party pursuant to Section 14.3(b), or if the
Indemnifying Party elects to defend the Indemnified Party pursuant to Section
14.3(b) but fails diligently and promptly to prosecute or settle the Third Party
Claim, then the Indemnified Party shall have the right to defend, at the sole
cost and expense of the Indemnifying Party (if the Indemnified Party is entitled
to indemnification hereunder), the Third Party Claim by all appropriate
proceedings, which proceedings shall be promptly and vigorously prosecuted by
the Indemnified Party to a final conclusion or settled. The Indemnified Party
shall have full control of such defense and proceedings, provided, however, that
the Indemnified Party may not enter into, without the Indemnifying Party's
consent, which shall not be unreasonably withheld, any compromise or settlement
of such Third Party Claim. Notwithstanding the foregoing, if the Indemnifying
Party has delivered a written notice to 



                                      -50-
<PAGE>   51

the Indemnified Party to the effect that the Indemnifying Party disputes its
potential liability to the Indemnified Party under this Article 14 and if such
dispute is resolved in favor of the Indemnifying Party, the Indemnifying Party
shall not be required to bear the costs and expenses of the Indemnifying Party's
defense pursuant to this Section or of the Indemnifying Party's participation
therein at the Indemnified Party's request, and the Indemnified Party shall
reimburse the Indemnifying Party in full for all costs and expenses of such
litigation. The Indemnifying Party may participate in, but not control any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 14.3(b), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation; provided, however, that if the
named parties to any such action (including any impleaded parties) include both
the Indemnifying Party and the Indemnified Party, and the Indemnifying Party has
been advised by counsel that there may be one or more legal defenses available
to the Indemnified Party, then the Indemnifying Party may employ separate
counsel and upon written notification thereof, the Indemnified Party shall not
have the right to assume the defense of such action on behalf of the
Indemnifying Party.

                  c.       In the event any Indemnified Party should have a
claim against any Indemnifying Party hereunder that does not involve a Third
Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a
written notice (the "Indemnity Notice") describing in reasonable detail the
nature of the claim, an estimate of the amount of damages attributable to such
claim and the basis of the Indemnified Party's request for indemnification under
this Agreement. If the Indemnifying Party does not notify the Indemnified Party
within sixty (60) days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by mediation or arbitration as
provided in Section 18.1 if the parties do not reach a settlement of such
dispute within thirty (30) days after notice of a dispute is given.

                  d.       Payments of all amounts owing by an Indemnifying
Party pursuant to this Article 14 relating to a Third Party Claim shall be made
within thirty (30) days after the latest of (i) the settlement of such Third
Party Claim, (ii) the expiration of the period for appeal of a final
adjudication of such Third Party Claim or (iii) the expiration of the period for
appeal of a final adjudication of the Indemnifying Party's liability to the
Indemnified Party under this Agreement. Payments of all amounts owing by an
Indemnifying Party pursuant to Section 14.3(d) shall be made within thirty (30)
days after the later of (i) the expiration of the sixty (60) day Indemnity
Notice period or (ii) the expiration of the period for appeal, if any, of a
final adjudication or arbitration of the Indemnifying Party's liability to the
Indemnified Party under this Agreement.

         14.4.    Exclusivity of Remedies. The remedies provided in this
Agreement shall be exclusive of any other rights or remedies available to one
party against the other, either at law or in equity; provided however such
remedies shall not be exclusive as to any claim based on fraud or any claim
under Section 16 of this Agreement. This Article 14 regarding indemnification
shall survive Closing.



                                      -51-
<PAGE>   52


                  14.5.    Costs, Expenses and Legal Fees. Each party hereto
agrees to pay the costs and expenses (including attorneys' fees and expenses)
incurred by the other parties in successfully (a) enforcing any of the terms of
this Agreement, or (b) proving that another party breached any of the terms of
this Agreement.

                  14.6.    Indemnification Limitations. Notwithstanding the
provisions of Sections 14.1 and 14.2, no party shall be required to indemnify
another notice of party with respect to a breach of a representation, warranty
or covenant unless the notice of claim for indemnification is delivered within
eighteen (18) months after the Closing Date, except that a claim for
indemnification for a breach of the representations and warranties contained in
Sections 3.3 and 4.1, may be made at any time, and a claim for indemnification
for a breach of the representations and warranties contained in Section 3.19 may
be made at any time within the applicable statute of limitations.

                  14.7.    Tax Benefits; Insurance Proceeds. The total amount of
any indemnity payments owed by one party to another party to this Agreement
shall be reduced by any correlative tax benefit received by the party to be
indemnified or the net proceeds received by the party to be indemnified with
respect to recovery from third parties or insurance proceeds and such

                           c.       at any time prior to the Closing Date by the

                  15.2.    Effect of Termination. In the event this Agreement is
terminated pursuant to Section 15.1, this Agreement shall be null and void and
of no further force and effect except that Purchaser, the Acquired Companies and
the Stockholder shall each be entitled to pursue, exercise and enforce any and
all remedies, rights, powers and privileges available at law or in equity,
subject to the limitations set forth in Section 14.1.

         16.      NON-COMPETITION AND CONFIDENTIALITY COVENANTS.

                  16.1.    The Stockholder's Non-Competition Covenant.

                           a.       The Stockholder recognizes that their
covenants contained in this Section 16.1 are an essential part of this Agreement
and that, but for the agreement of the Stockholder to comply with such
covenants, Purchaser would not have entered into this Agreement. The Stockholder
acknowledges and agrees that their covenant not to compete is necessary to
ensure the continuation of the Business (as defined below) and is necessary to
protect the reputation of Purchaser, and that irreparable and irrevocable harm
and damage will be done to Purchaser if the Stockholder competes with Purchaser.
The Stockholder accordingly agrees that for a period of five (5) years from the
Closing Date, it shall not:

                                    i)       directly or indirectly, either as
principal, agent, independent contractor, consultant, director, officer,
employee, employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for their own benefit or for the
benefit of any other person or entity knowingly (A) hire, attempt to hire,
contact or solicit with respect to hiring any employee of Purchaser (or of any
of its direct or indirect subsidiaries) or (B) induce or otherwise counsel,
advise or encourage any employee of Purchaser (or of any of its direct or
indirect subsidiaries) to leave the employment of Purchaser;



                                      -53-
<PAGE>   54

                                    ii)      act or serve, directly or
indirectly, as a principal, agent, independent contractor, consultant, director,
officer, employee, employer or advisor or in any other position or capacity with
or for, or acquire a direct or indirect ownership interest in or otherwise
conduct (whether as stockholder, partner, investor, joint venturer, or as owner
of any other type of interest), any Competing Business as such term is defined
herein; provided, however, that this clause (ii) shall not prohibit Stockholder
from being the owner of up to 1% of any class of outstanding securities of any
company or entity if such class of securities is publicly traded; or

                                    iii)     directly or indirectly, either as
principal, agent, independent, contractor, consultant, director, officer,
employee, employer, advisor, stockholder, partner or in any other individual or
representative capacity whatsoever, either for their own benefit or for the
benefit of any other person or entity, call upon or solicit any customers or
clients of the Business for the purpose of providing management services to eye
care professionals or providing managed care services to third party payors or
eye care professionals.

                           b.       For the purposes of this Section 16.1, the
following terms shall have the meanings set forth below:

                                    i)       "Business" shall mean providing
management services to eye care professionals and providing managed care
services to third party payors or eye care professionals.

                                    ii)      "Competing Business" shall mean an
individual, business, corporation, association, firm, undertaking, company,
partnership, joint venture, organization or other entity that either (A)
conducts a business substantially similar to the Business within any State where
the Acquired Companies or the Subsidiaries engage in business, or (B) provides
or sells a service which is the same or substantially similar to, or otherwise
competitive with the services provided by the Business within any State where
the Acquired Companies or the Subsidiaries engage in business.

                           c.       Should any portion of this Section 16.1 be
deemed unenforceable because of the scope, duration or territory encompassed by
the undertakings of the Stockholder hereunder, and only in such event, then the
Stockholder and Purchaser consent and agree to such limitation on scope,
duration or territory as may be finally adjudicated as enforceable by a court of
competent jurisdiction after the exhaustion of all appeals.

                           d.       This covenant shall be construed as an
agreement ancillary to the other provisions of this Agreement, and the existence
of any claim or cause of action of a Stockholder against Purchaser, whether
predicated on this Agreement or otherwise, shall not constitute a defense to the
enforcement by Purchaser of this covenant. Without limiting other possible
remedies to Purchaser for breach of this covenant, the Stockholder 


                                      -54-
<PAGE>   55

agrees that injunctive or other equitable relief will be available to enforce
the covenants of this provision, such relief to be without the necessity of
posting a bond, cash or otherwise. The Stockholder and Purchaser further
expressly acknowledge that the damages that would result from a violation of
this non-competition covenant would be impossible to predict with any degree of
certainty, and agree that liquidated damages in the amount of Stock Purchase
Consideration is reasonable in light of the severe harm to the Business and
Purchaser which would result in the event that a violation of this
non-competition covenant were to occur.

                  16.2.    The Stockholder's Confidentiality Covenant. From the
date hereof, the Stockholder shall not, directly or indirectly, use for any
purpose, or disclose to any third party, any information of Purchaser or the
Acquired Companies, as appropriate (whether written or oral), including any
business management or economic studies, customer lists, proprietary forms,
proprietary business or management methods, marketing data, fee schedules, or
trade secrets of Purchaser or of the Acquired Companies, as applicable, and
including the terms and provisions of this Agreement and any transaction or
document executed by the parties pursuant to this Agreement. Notwithstanding the
foregoing, the Stockholder may disclose information that they can establish (a)
is or becomes generally available to and known by the public or optometric
community (other than as a result of an unpermitted disclosure directly or
indirectly by the Stockholder or its Affiliates, advisors or representatives);
(b) is or becomes available to such Stockholder on a nonconfidential basis from
a source other than Purchaser, the Acquired Companies or their respective
Affiliates, advisors or representatives, provided that such source is not and
was not bound by a confidentiality agreement with or other obligation of secrecy
to Purchaser, the Acquired Companies or their respective Affiliates, advisors or
representatives of which such Stockholder has knowledge; or (c) has already been
or is hereafter independently acquired or developed by such Stockholder without
violating any confidentiality agreement with or other obligation of secrecy to
Purchaser, the Acquired Companies or their respective Affiliates, advisors or
representatives. Without limiting the other possible remedies to Purchaser for
the breach of this covenant, the Stockholder agrees that injunctive or other
equitable relief shall be available to enforce this covenant, such relief to be
without the necessity of posting a bond, cash or otherwise. The Stockholder
further agrees that if any restriction contained in this Section 16.2 is held by
any court to be unenforceable or unreasonable, a lesser restriction shall be
enforced in its place and the remaining restrictions contained herein shall be
enforced independently of each other.

                  16.3.    Survival. The parties acknowledge and agree that this
Article 16 shall survive the Closing of the transactions contemplated herein.

         17.      DISPUTES.

                  17.1.    Mediation and Arbitration. Any dispute, controversy
or claim (excluding claims arising out of an alleged breach of Article 16 of
this Agreement) arising out of this Agreement, or the breach thereof, that
cannot be settled through negotiation shall be settled (a) first, by the parties
trying in good faith to settle the dispute by mediation under the Commercial
Mediation Rules of the AAA (such mediation session to be held in Tampa, Florida,
and to commence within 15 days of the appointment of the mediator by the AAA),
administered by the AAA under its Commercial Arbitration Rules (such arbitration
to be held in Tampa, Florida, before a single arbitrator and to commence within
15 days of the appointment of the arbitrator by the AAA), and judgment on the
award rendered by the arbitrator may be entered in any court having jurisdiction
thereof.

other taxes and charges imposed by the State of Florida, if any, which may
become payable in connection with the transactions and documents contemplated
hereunder.

                  18.2.    Remedies Not Exclusive. No remedy conferred by any of

Agreement is intended to be exclusive of any other remedy, and each and every
remedy shall be cumulative and shall be in addition to every other remedy given
hereunder or now or hereafter existing at law or in equity or by statute or
otherwise. The election of any one or more remedies by any party hereto shall
not constitute a waiver of the right to pursue other available remedies.

                  18.3.    Parties Bound. Except to the extent otherwise
expressly provided herein, this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective heirs, representatives,
administrators, guardians, successors and assigns; and no other person shall
have any right, benefit or obligation hereunder.

                  18.4.    Notices. All notices, reports, records or other
communications that are required or permitted to be given to the parties under

Agreement and shall be executed in writing by the party to be bound thereby. No

prior confidentiality agreements and letters of intent between or among

any stock certificate is issued.

                  18.14.   Multiple Counterparts. This Agreement may be executed
in one or more counterparts, each of which shall be deemed an original, but all
of which together shall constitute one and the same instrument.

                          STOCK DISTRIBUTION AGREEMENT

         This Stock Distribution Agreement ("Agreement"), dated as of December
30, 1997, is by and between Vision Twenty-One, Inc. ("Vision 21"), a Florida
corporation and any successor, and LaserSight Incorporated (the "Stockholder"),
a Delaware corporation.

                                R E C I T A L S

         A.      The Stockholder and Vision 21 have executed that certain Stock
Purchase Agreement effective as of December 1, 1997 (the "Stock Purchase
Agreement"), pursuant to which Vision 21 has agreed to acquire all of the
issued and outstanding stock of MEC Health Care, Inc. and LSI Acquisition,
Inc., in exchange for delivery to the Stockholder of 812,500 shares of Vision
21 common stock and the Additional Shares (as defined in the Stock Purchase
Agreement, collectively, the "Restricted Shares") and $6,500,000 in cash, as
more fully set forth in the Stock Purchase Agreement.

         B.      The Stockholder and Vision 21 desire to enter into the plan of
distribution (the "Plan of Distribution") described herein for liquidation of
the Restricted Shares through, at Vision 21's sole option, a "shelf"
registration statement, private placement, redemption by Vision 21 or other
method acceptable to Vision 21 and the Stockholder.

         NOW THEREFORE, for and in consideration of the mutual agreements,
terms, covenants and conditions herein and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties agree as follows:

         1.      Plan of Distribution of Restricted Shares.

                 (a)      Stockholder agrees that on each date specified in
Section 1(b) below that number of the Restricted Shares so indicated in
connection with such date shall, at Vision 21's sole option, either (i) be sold
through a market maker designated by Vision 21 through a "shelf" registration
statement (the "Registration Statement") pursuant to Sections 2, 3 and 4
hereof, (ii) be sold through a market maker designated by Vision 21 through a
private placement pursuant to Sections 5, 6 and 7 hereof or other method of
sale reasonably acceptable to Vision 21 and the Stockholder, or (iii) be
purchased by Vision 21 pursuant to Section 8 hereof.

                 (b)      The Restricted Shares shall be liquidated on, or, at
Vision 21's option, before the following specified dates in the following
specified increments in accordance with the terms of this Agreement:

                                                                      to be Liquidated

                       March 2 through March 31, 1998     166,667 and 25% of the Additional Shares

                       April 1 through April 30, 1998     229,167 and 25% of the Additional Shares

                       May 1 through May 29, 1998         250,000 and 25% of the Additional Shares
</TABLE>

                 (c)      Vision 21 agrees that no matter how the Restricted
Shares are liquidated pursuant to this Agreement on each of the dates set forth
in Section 1(b) hereof the Stockholder shall receive from Vision 21 and/or the
party purchasing Restricted Shares a sum equal to the number of Restricted
Shares to be sold on such date times the closing price of Vision 21 common
stock as quoted by the NASDAQ National Market System on such date.  Vision 21
also agrees the Stockholder shall receive a minimum of an aggregate of Six
Million Five Hundred Thousand Dollars ($6,500,000) and a maximum of an
aggregate of Seven Million Four Hundred Seventy-Five Thousand Dollars
($7,475,000) in connection with the liquidation of the Restricted Shares.  In
the event the Stockholder realizes aggregate gross proceeds from the sale of
the Restricted Shares equal to Seven Million Four Hundred Seventy-Five Thousand
Dollars ($7,475,000) prior to all Restricted Shares being liquidated pursuant
to the Plan of Distribution, the Restricted Shares not yet liquidated, if any,
shall be returned to Vision 21.  If by 4:00 p.m., New York time, on May 29,
1998, the Stockholder has not realized the sum of at least Six Million Five
Hundred Thousand Dollars ($6,500,000) from the sale of the Restricted Shares,
Vision 21 shall pay the Stockholder by wire transfer of immediately available
funds on May 29, 1998 the cash sum which is equal to Six Million Five Hundred
Thousand Dollars ($6,500,000) less the proceeds received through such date by
the Stockholder from the sale of Restricted Shares.  However, if on such date
not all Restricted Shares have been liquidated and Vision 21 exercises its
right under Section 8 of this Agreement to redeem such Restricted Shares, then,
such Restricted Shares shall be returned to Vision 21 in connection with the
purchase thereof.

                 (d)      Stockholder agrees not to sell, pledge, transfer or
dispose of the Restricted Shares except in accordance with the terms of this
Agreement and the terms of that certain Stock Pledge Agreement between the
Stockholder and Foothill Capital Corporation dated as of December 30, 1997.

                 (e)      The parties acknowledge and agree that the number of
Restricted Shares (and therefore the Six Million Five Hundred Thousand Dollar
($6,500,000) minimum payment contemplated by Section 1(c) and the Seven Million
Four Hundred Seventy-Five Thousand Dollar ($7,475,000) maximum payment
contemplated by Section 1(c)) shall be subject to the adjustments contemplated
by Section 2.5 of the Stock Purchase Agreement.

         2.               Shelf Registration.

                 (a)      Vision 21 may, in its sole discretion, file and cause
to be declared effective as soon as practicable a Registration Statement
pursuant to the Securities Act of 1933, as amended (the "Securities Act") for
all of the Restricted Shares not yet liquidated in accordance with the Plan of
Distribution, which form will then be available for the sale of the Restricted
Shares in accordance with the Plan of Distribution.  The Registration Statement
shall be kept effective until such time as all of the Restricted Shares have
been liquidated, provided that Vision 21 may terminate an effective
Registration Statement prior to all of the Restricted Shares being 




                                      2

<PAGE>   3

liquidated if on the date of such termination Vision 21 is in compliance with
the terms of this Agreement.

                 (b)      Vision 21 shall have the right to extend, temporarily
suspend or delay the effectiveness of any Registration Statement for a period
of up to thirty (30) days if, upon the advice of counsel, such extension,
suspension or delay is advisable and in the best interests of Vision 21 because
of the existence of non-public material information, or to allow Vision 21 to
complete any pending audit of its financial statements, any material public
financing plan, any pending material acquisition, or to release audited
financial statements for any pending material acquisition as required by the
Securities and Exchange Commission (the "Commission"), provided that Vision 21
shall only be entitled to one such suspension during the Plan of Distribution.

                 (c)      The Stockholder agrees to cooperate with Vision 21 in
all reasonable respects in connection with registration of the Restricted
Shares, including timely supplying all information and executing and returning
all documents requested by Vision 21 which are reasonable and customary.

                 (d)      Vision 21 shall be entitled to include in the
Registration Statement any other securities of Vision 21 (whether to be offered
by Vision 21 or other Vision 21 security holders and regardless of the proposed
terms of the transfer or sale of such other securities).

         3.      Registration Covenants of Vision 21.  In the event Vision 21

Vision 21 hereby covenants and agrees to:

                 (a)      Take such steps as may be necessary to comply with
the Blue Sky laws of such states as may be required by law; provided that in no
event shall Vision 21 be obligated to qualify to do business in any state where

unlimited service of process in any state where it is not at such time so
subject;

                 (b)      Pay all fees and expenses of Vision 21's counsel, all

printing costs, experts' fees and expenses, costs of post-effective amendments,
Eligible Broker's Fees (as defined herein), and all other usual and customary
expenses in connection with the Registration Statement;

                 (c)      Notify the Stockholder promptly after it shall
receive notice thereof, of the date and time when such Registration Statement
and each post-effective amendment thereto has become effective or a supplement
to any prospectus forming a part of such Registration Statement has been filed
and provide the Stockholder with such number of prospectuses, and any amendments
thereof or supplements thereto, the Stockholder may reasonably request;

                 (d)      Promptly notify the Stockholder of any request by the
Commission for the amending or supplementing of such registration statement or
prospectus or for additional information and provide the Stockholder with
copies of such requests;

event has occurred as the result of which any such prospectus or any other
prospectus as then in effect may include an 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 not misleading;

                 (f)      Advise the Stockholder promptly after it shall
receive notice or obtain knowledge thereof, of the issuance of any stop order
by the Commission suspending the effectiveness of such Registration Statement
or the initiation or threatening of any proceeding for that purpose and
promptly use its best efforts to prevent the issuance of any stop order or to
obtain its withdrawal if such stop order should be issued; and

                 (g)      Once the Registration Statement is effective Vision
21 shall, on or before the relevant date set forth in Section 1(b) hereof,
instruct its transfer agent to immediately remove any restrictive legend from
that number Restricted Shares then eligible to be sold pursuant to the Plan of
Distribution.

         For purposes of Sections 3(b) and 6(b) "Eligible Broker's Fees" shall
mean brokers', underwriters' and placement agents' fees, commissions and
discounts related to the liquidation of Restricted Shares pursuant to a
Registration Statement or a private placement, provided that if the Stockholder
receives in excess of Six Million Five Hundred Thousand Dollars ($6,500,000)
from the liquidation of Restricted Shares then the amount so received by the
Stockholder in excess of Six Million Five Hundred Thousand Dollars
($6,500,000), shall be utilized to pay all customary brokers', underwriters'
and placement agents' fees, commissions and discounts related to the
liquidation of Restricted Shares, until such fees are paid in full and
thereafter such excess shall be retained by the Stockholder subject to the
limitations of Section 1(c).

make the statements in such a document not misleading, provided that Vision 21
will not be liable to Stockholder to the extent that such loss, claim,

reliance on and in conformity with written information furnished to Vision 21 by
Stockholder or through any attorney-in-fact for Stockholder, expressly for
inclusion in the Registration Statement or any prospectus included in the

and each of Vision 21's directors and officers from and against any and all
losses, claims, liabilities, expenses and damages (including any and all
investigative, legal and other expenses reasonably incurred in connection with,
and any amount paid in settlement of, any addition, suit or proceeding or any
claim asserted), to which they, or any of them, may become subject under the
Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims,
liabilities, expenses or damages arise out of or are based on any untrue
statement or alleged untrue statement of a material fact required to be stated
in the Registration Statement or private placement memorandum or necessary to
make the statements in such documents not misleading; provided that Stockholder
will not be liable except to the extent that such loss, claim, liability,
expense or damage arises from or is based upon an untrue statement or omission
or alleged untrue statement or omission made in reliance on and in conformity
with written information furnished to Vision 21 by the Stockholder, or by the
Stockholder through any attorney-in-fact, expressly for inclusion in the
registration statement or any prospectus included in such registration statement
or a private placement memorandum.

         11.     Defense of Claim.  Promptly after receipt by an indemnified
party of notice of the commencement of any action, the indemnified party shall
notify the indemnifying party in writing of the commencement thereof if a claim
in respect thereof is to be made against any indemnifying party under this
Agreement, but the omission of such notice shall not relieve the indemnifying
party from liability which it may have to the indemnified party under this
Agreement, except to the extent that the indemnifying party is actually
prejudiced by such failure to give notice, and shall not relieve the
indemnifying party from any liability which it may have to any indemnified
party otherwise than under this Agreement.  In case any action is brought
against the indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
in, and to the extent that it chooses, 





                                      6

<PAGE>   7

to assume the defense thereof with counsel reasonably satisfactory to the
indemnified party, and after notice from the indemnifying party to the
indemnified party that it so chooses, the indemnifying party shall not be liable
for any legal or other expenses subsequently incurred by the indemnified party
in connection with the defense thereof; provided however that (i) if the
indemnifying party fails to take reasonable steps necessary to defend diligently
the claim within twenty (20) days after receiving notice from the indemnified
party that the indemnified party believes the indemnifying party has failed to
diligently defend such claim, or (ii) if the indemnified party who is a
defendant in any action or proceeding which is also brought against the
indemnifying party reasonably shall have concluded that there are legal defenses
available to the indemnified party which conflict with the defense strategy of
the indemnifying party, or (iii) if in the opinion of counsel for the
indemnified party a conflict of interest exists that requires separate
representation of the indemnified party and the indemnifying party, then the
indemnified party shall have the right to assume or continue its own defense as
set forth above and the indemnifying party shall reimburse the indemnified party
for the costs of such defense.  In no event shall the indemnifying party be
reasonable for the fees of more than one firm for all indemnified parties.

         12.     Survival of Indemnity.  The indemnifications provided by this
Agreement shall be a continuing right to indemnification and shall survive the
registration and sale of any securities by any person entitled to
indemnification hereunder and the expiration or termination of this Agreement.

         13.     Remedies.  If Vision 21 fails to take the actions or make the
payments described in Sections 1(a) or 1(c) hereof on or before the date which
is three business days after the date specified in such Sections (the "Default
Date") then the following shall apply:

                 (a)       Vision 21 shall prepare, and, on or prior to 20
business days after the Default Date (the "Filing Date"), file with the
Commission a registration statement on Form S-3 (or, if Form S-3 is not then
available, on such form of registration statement as is then available to
effect a registration of all of the Restricted Shares) covering the resale of
all of the Restricted Shares.  Such registration statement (and each amendment
or supplement thereto) shall be provided to (and subject to the approval of
(which approval shall not be unreasonably withheld or delayed)) the Stockholder
and their counsel prior to its filing or other submission, except to the extent
that a post-effective amendment of such registration statement, or supplement
to the related prospectus, is required by applicable securities law to be filed
before such approval can reasonably be obtained, in which case Vision 21 shall
provide a copy of such amendment or supplement, as applicable, to the
Stockholder and their counsel as soon as practicable after such filing.  Vision
21 shall cause such registration statement to become effective as soon as
practicable after such filing and keep such registration statement effective at
all times until such date as is the earlier of (i) the date on which all of the
Restricted Shares have been sold, and (ii) the date on which all of the
Restricted Shares may be immediately sold to the public without registration
conditions, or limitations, whether pursuant to Rule 144(k) or otherwise (the
"Registration Period").

                 Vision 21 shall cause such registration statement to become
effective as soon as practicable, but in no event later than the ninetieth
(90th) day following the Default Date (the "Registration Deadline").  If (i)
such registration statement covering all of the Restricted Shares 




                                      7

<PAGE>   8

is not declared effective by the Commission on or before the Registration
Deadline, or (ii) after such registration statement has been declared effective
by the Commission, sales of all the Restricted Shares cannot be made pursuant to
such registration statement (by reason of a stop order or Vision 21's failure to
update the registration statement), then Vision 21 will make payments to the
Stockholder in such amounts and at such times as shall be determined pursuant to
this Section 13(a) as partial relief for the damages to the Stockholder by
reason of any such delay in or reduction of their ability to sell the Restricted
Shares (which remedy shall not be exclusive of any other remedies available at
law or in equity).  Vision 21 shall pay to the Stockholder an amount equal to
(i) (A) .01 per month (prorated daily during the first 30 days after the
Registration Deadline) and .02 per month, prorated daily (thereafter) times (B)
the aggregate value of the Restricted Shares not yet liquidated pursuant to the
Plan of Distribution (such value shall be calculated utilizing the closing price
of Vision 21 common stock as quoted by the NASDAQ National Market System as of
the date the Restricted Stock was issued) times (ii) the sum of:  (A) the number
of months (prorated per day for partial months) following the Registration
Deadline but prior to the date such registration statement is declared effective
by the Commission plus (B) the number of months (prorated per day for partial
months) following the Registration Deadline but prior to the termination of the
Registration Period that sales cannot be made pursuant to the Registration
Statement after the Registration Statement has been declared effective.  Such
amounts shall be paid in cash within five business days after the end of each
period that gives rise to such obligation, provided that, if any such period
extends for more than 30 days, payments shall be made for each such 30 day
period within five business days after the end of such 30 day period.

                 (b)       The Stockholder will be free to sell all of the
Restricted Shares in a private placement or other transaction subject only to
compliance with applicable securities laws, including, without limitation, to
persons in the United States whom the Stockholder reasonably believes to be
qualified institutional buyers as defined in Rule 144A under the Securities
Act, as such rule may be amended from time to time ("Rule 144A"), in
transactions under Rule 144A and (ii) to a limited number of other
institutional "accredited investors" (as defined in Rule 501(a)(1), (2), (3)
and (7) under Regulation D of the Act) in private sales exempt from
registration under the Act (such persons specified in clauses (i) and (ii)
being referred to herein as the "Eligible Purchasers").  Sales to Eligible
Purchasers shall be made in compliance with applicable securities laws and any
shares so sold shall bear appropriate restrictive legends.

                 Vision 21 agrees to take all necessary steps to facilitate the
Stockholder's sale of the Restricted Shares to Eligible Purchasers.  During the
period of time the Stockholder is trying to sell the Restricted Shares pursuant
to this Section 13(b), Vision 21 shall advise the Stockholder promptly and, if
requested by it, shall promptly confirm such advice in writing, of any material
adverse change, or of any event or condition known to Vision 21 which is
reasonably likely to result in a material change, in the condition (financial
or other), business, prospects, liabilities (contingent or otherwise),
properties, net worth, solvency or results of operations of Vision 21 (whether
or not arising in the ordinary course of business), or of the happening of any
event, any information becoming known or the existence of any condition that
would require any amendment or supplement to any Vision 21 filing with the
Commission so that such filings would 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 the light of the circumstances
under which they were made, not misleading.




                                      8

                 Vision 21 will cooperate with the Stockholder and with its
counsel in connection with the qualification of the Restricted Shares for
offering and sale by the Stockholder and by dealers to Eligible Purchasers
under the securities or Blue Sky laws of such jurisdictions as the Stockholder
may designate and will file such consents to service of process or other
documents necessary or appropriate in order to effect such qualification.

                 For so long as any of the Restricted Shares are held by the
Stockholder and are "restricted securities" within the meaning of Rule
144(a)(3) under the Act and during any period in which Vision 21 is not subject
to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended,
Vision 21 will furnish to holders and beneficial owners of the Restricted
Shares and prospective purchasers of Restricted Shares designated by such
holders, upon request of such holders or beneficial owners or such prospective
purchasers, the information required to be delivered pursuant to Rule
144A(d)(4) under the Act to permit compliance with Rule 144A in connection with
resales of the Restricted Shares.

                 (c)       The Stockholder will be free to seek all other
remedies which may be available at law or in equity in connection with Vision
21's failure to comply with the terms of this Agreement.

         14.     Listing on Securities Exchanges.  Vision 21 shall cause the
listing and the continuation of listing of Vision 21's common stock on the
NASDAQ National Market.  By February 1, 1998 Vision 21 shall file the
appropriate application (and pay the associated fee) for listing the Restricted
Shares with NASDAQ.

         15.     SEC Filings.  During the period of time the Stockholder owns
the restricted Shares Vision 21 shall supply the Stockholder with a copy of all
annual or quarterly reports of Vision 21 and such other reports and documents
filed by the Company with the Commission.  Such copies shall be supplied within
three business days after the filing thereof with the Commission.

         16.     Non-Transferability.  The benefits set forth herein, including
indemnification by Vision 21, are granted for the sole and personal benefit of
the Stockholder and may not be transferred or assigned, provided that Vision 21
consents to the terms and conditions of that certain Collateral Assignment among
Vision 21, the Stockholder and Foothill Capital Corporation dated December 30,
1997.

         17.     Delay of Registration.  Stockholder agrees that it shall have
no right to obtain or seek an injunction restraining or otherwise delaying any
registration statement filed by Vision 21.

         18.     Notices.

                 (a)      All communications under this Agreement shall be in
writing and shall be sufficient in all respects if personally delivered or
mailed by prepaid certified or registered mail, return receipt requested,
addressed as follows:

VISION TWENTY-ONE ANNOUNCES TWO ACQUISITIONS

LARGO, FL - Dec. 31, 1997- Vision Twenty-One, Inc. (Nasdaq: EYES), an eye care
practice management company, announced the completion of the acquisitions of 100
percent of the stock of LSI Acquisition, Inc. and MEC Health Care, Inc. (MEC),
wholly owned subsidiaries of Lasersight, Inc.

The transactions, closed effective December 1, 1997, are accretive to Vision
Twenty-One's earnings on a pro forma basis. Aggregate consideration for these
acquisitions was approximately $13 million, consisting of cash in the amount of
$6.5 million and 812,500 shares of Vision Twenty-One common stock. The
consideration is subject to certain adjustments.

LSI Acquisition has a twenty-five year service agreement with Northern N.J. Eye
Institute, an ophthalmology practice located in South Orange, New Jersey, with
four locations including an ambulatory surgery center. The acquisition allows
Vision Twenty-One to further expand its Local Area Delivery Systems (LADS) in
the state of New Jersey. The estimated clinic revenues of N.J. Eye Institute
were $4.0 million for the year ended December 31, 1997.

Vision Twenty-One also acquired MEC, a managed care company located in
Baltimore, Maryland. MEC operates an Administrative Service Center and holds
eleven managed eye care contracts covering over 650,000 capitated optometry and
ophthalmology lives serviced through a provider panel consisting of over 400
contracted eye care physicians, principally located in the greater Baltimore,
Washington, D.C. and Virginia metropolitan areas. With the substantial increase
in covered lives, this acquisition continues Vision Twenty-One's strategy of
capturing managed care business. The estimated revenues from MEC were $8.7
million for the year ended December 31, 1997.

Theodore Gillette, Chairman, President and CEO of Vision Twenty-One, stated, "We
are excited about the continued expansions in the state of New Jersey to offer
the full continuum of eye care services. In addition, the acquisition of MEC
significantly increases the number of managed care lives Vision Twenty-One
covers to over 4.8 million."

Vision Twenty-One, Inc. provides a wide range of management and administrative
services to its Local Area Delivery Systems, (LADS), which are designed to
provide for integrated networks of optometrists, ophthalmologists, ambulatory
surgery centers and retail optical centers which offer the full continuum of eye
care services in local markets served by the Company. Prior to these
transactions, Vision Twenty-One provided its services to 39 LADS located in 26
states through which 5,810 Affiliated Providers deliver eye care services. In
addition, the Company has 6,190 eye care professionals available for potential
managed care business in future markets.

Statements contained in this press release that are not based on historical
fact, including statements of revenues and future expansion of Vision
Twenty-One, are forward-looking statements. These forward looking statements
contain statements regarding expected future profitability to the Company
resulting from the acquisitions and the integration of the Company's Local Area
Delivery System to offer the full continuum of eye care services. Actual results
may differ materially from the statements made as a result of various factors
including, but not limited to, the risks associated with the Company's ability
to finance future growth; the Company's ability to successfully and profitably
manage its managed care practices; the Company's ability to retain key employees
and agents of acquired businesses and managed practices; the loss of significant
management contract(s); profitability at sites managed by Vision Twenty-One; the
ability of the Company to successfully integrate its acquisitions; the ability
of the Company to effectively manage the cost of its acquisitions; any material
impact on future revenues of its acquired businesses; changes in insurance
coverage, government laws and regulations regarding health care or managed care
contracting; the ability of the Company to retain managed care contracts with
acceptable terms; and other risks, including those identified in the Company's
most recent 10-Q and S-1 registration statement and in other documents filed by
the Company with the U.S. Securities and Exchange Commission (SEC).
