         that all necessary contingencies have been satisfied). Diluted loss per
         common share is computed  using the weighted  average  number of common
         shares,  contingently  issuable  shares,  and common share  equivalents
         outstanding  during  each  period.  Common  share  equivalents  include
         options,  warrants to purchase Common Stock, and convertible  Preferred
         Stock and are  included in the  computation  using the  treasury  stock
         method if they would have a dilutive effect.

NOTE 3   ADOPTION OF NEW ACCOUNTING STANDARD

         The Company  adopted  the  provisions  of the  Statement  of  Financial
         Accounting Standards (SFAS) No. 130 "Reporting Comprehensive Income" on
         January 1, 1998.  SFAS No. 130  requires  companies  to classify  items
         defined as "other comprehensive  income" by their nature in a financial
         statement and to display the accumulated balance of other comprehensive
         income separately from retained earnings and additional paid-in capital
         in the equity section of the balance  sheet.  The Company has presented
         information for all periods reported below to conform to this standard.

NOTE 5   MARKETABLE EQUITY SECURITIES

         Through  September  30,  1998,  the Company  received  net  proceeds of
         $6,527,452  in  exchange  for the sale of shares of Vision  Twenty-One,
         Inc.  (Vision 21) common stock received in connection with the December
         1997 sale of MEC Health  Care,  Inc.  (MEC) and LSI  Acquisition,  Inc.
         (LSIA) to Vision 21. Through September 30, 1998, the Company realized a
         gain on the sale of such stock of  $27,452.  The  Company  is  pursuing
         additional  amounts  believed  due from Vision 21 pursuant to the Stock
         Distribution Agreement between the companies.

NOTE 6   SALE OF INTERNATIONAL PATENT RIGHTS

         In February  1998,  the Company  closed a  transaction  for the sale of
         certain  rights in  certain  patents  to Nidek  Co.,  Ltd.  (Nidek)  in
         exchange for $6.3  million in cash (of which  $200,000 was withheld for
         the payment of Japanese taxes).  The Company  transferred all rights in
         those patents  issued in countries  outside of the United States (U.S.)
         but retained the  exclusive  right to use and  sublicense  the non-U.S.
         patents  in  all  fields  other  than  ophthalmic,  cardiovascular  and
         vascular.  The Company received a non-exclusive license to the non-U.S.
         patents in the ophthalmic field. In addition, the Company has granted a
         non-exclusive  license to use those patents  issued in the U.S.,  which
         resulted in $1.2 million of deferred royalties that are being amortized
         to income  over  three  years.  The  transaction  did not result in any
         current gain or loss,  but reduced the Company's  amortization  expense
         over the  remaining  useful  life  (approximately  8 years) of the U.S.
         patents.

NOTE 7   COMMITMENTS AND CONTINGENCIES

         Photomed Amendment
         ------------------

         On September  11,  1998,  the Company  entered  into an amendment  with
         Photomed,  Inc.  (Photomed)  amending the  Agreement and Plan of Merger
         dated  July 15,  1997 by which  the  Company  acquired  a laser in situ
         keratomileusis  (LASIK)  Pre-Market  Approval  (PMA)  application.  The
         amended terms of the agreement  follow.  In September 1998,  based on a
         U.S. Food and Drug Administration (FDA) approval received in July 1998,
         the Company paid Photomed a total of $1,740,000,  of which $990,000 was
         paid in cash and the  balance  paid  through  the  issuance  of 187,500
         shares of Common Stock. Upon receipt of FDA approval of a laser for the
         treatment of  hyperopia,  utilizing  part or all of the know how of the
         laser  acquired,  the  Company is required to issue up to $1 million in
         Common Stock with the obligation  decreasing  approximately  $2,740 per
         day beginning June 1, 1999 and  terminating  June 1, 2000. Upon receipt
         of FDA approval of  equivalency  of the Company's  refractive  scanning
         laser to the laser acquired, payment of up to $1 million in cash is due
         if the  approval is obtained  within four months after  Photomed  takes
         delivery of the Company's  refractive  scanning laser.  Such obligation
         decreases  approximately  $2,740 per day after such four month  period.
         If, prior to August 1, 1999,  the  Company's  gross sales of refractive
         lasers  for final use within the United  States  exceeds  $14  million,
         Photomed is to receive 25% of gross sales in excess of $14 million.

         Litigation
         ----------

         On  August  3,  1998,  Mercacorp,  Inc.  filed an  action  in the U. S.
         District  Court  for the  Eastern  District  of New  York  against  the
         Company, the President and Chief Executive Officer of the Company, Wall
         & Broad Equities,  Inc., a "purported investment banking establishment"
         and Isaac Weinhouse, the principal of such purported investment banking
         establishment,  asserting violations of Section 10(b) of the Securities
         and  Exchange Act of 1934 and common law fraud in  connection  with the
         alleged  issuance  of  false  press  releases,  misrepresentations  and
         omissions by all of the  defendants  on which the  plaintiff  allegedly
         relied in purchasing the Company's  Common Stock. The action seeks both
         actual and punitive monetary damages from the Company in the amounts of
         $5 million and $50 million,  respectively.  On November  11, 1998,  the
         plaintiff dismissed the action, with prejudice,  and the parties agreed
         to a release  of all  claims.  In  connection  with the  dismissal  and
         release  of claims  the  Company  issued  the  plaintiff  two  separate
         warrants  to  purchase  Common  Stock.  Under  the first  warrant,  the
         plaintiff is entitled to purchase up to 750,000  shares of Common Stock
         at an  exercise  price of $4.00 per  share,  the  closing  bid price on

         November  10,  1998,  and under the second  warrant,  the  plaintiff is
         entitled  to  purchase  up to  750,000  shares  of  Common  Stock at an
         exercise price of $5.00 per share. Both of the warrants contain certain
         prohibitions  against  assignment and transfer to third parties as well
         as other  terms  and  conditions.  No  provision  has been  made in the
         condensed consolidated financial statements with respect to this matter
         as of September 30, 1998.
                                   
                    
 
NOTE 8   STOCKHOLDERS' EQUITY

         TLC Private Placement

         In June 1998, the Company entered into a Securities  Purchase Agreement
         with TLC The Laser  Center  Inc.  (TLC),  pursuant to which the Company
         issued  2,000,000   shares  of   newly-created   Series  C  Convertible
         Participating  Preferred  Stock (Series C Preferred  Stock) with a face
         value of $4.00 per share,  resulting in an aggregate  offering price of
         $8 million.  The Series C Preferred  Stock is  convertible  by TLC on a
         fixed,  one-for-one  basis into 2,000,000 shares of Common Stock at any
         time until June  2001,  on which date all shares of Series C  Preferred
         Stock then  outstanding  will  automatically be converted into an equal
         number of shares of Common Stock.

         The net proceeds to the Company,  after deduction of costs of issuance,
         was approximately $7.9 million. The net proceeds were partially used to
         repurchase  all  525  outstanding  shares  of the  Company's  Series  B
         Convertible Participating Preferred Stock (Series B Preferred Stock) on
         June 5, 1998 for approximately $6.3 million, including a 20% premium.

         Pequot  Private  Placement  

         In June 1998, the Company entered into a Securities  Purchase Agreement
         with Pequot Private  Equity Fund,  L.P.,  Pequot Scout Fund,  L.P., and
         Pequot Offshore Private Equity Fund, Inc.  (Pequot Funds),  pursuant to
         which  the  Company  issued,  collectively,  2,000,000  shares  of  the
         newly-created  Series  D  Convertible   Participating  Preferred  Stock
         (Series  D  Preferred  Stock)  with a face  value of $4.00  per  share,
         resulting in an aggregate  offering  price of $8 million.  The Series D
         Preferred  Stock is  convertible  by the Pequot Funds on a  one-for-one
         basis  into  2,000,000  shares of Common  Stock at any time  until June
         2001,  on which  date all  shares  of  Series D  Preferred  Stock  then
         outstanding  will  automatically  be converted  into an equal number of
         shares of Common  Stock.  The  Series D  Preferred  Stock is subject to
         certain anti-dilution adjustments if the Company issues or sells shares
         of Common Stock before June 2001 at a price per share less than $4.00.

         The net proceeds to the Company,  after deduction of costs of issuance,
         was approximately $7.9 million.

         Series B Preferred Stock Repurchase

         In June 1998,  the  Company  repurchased  the  remaining  525 shares of
         Series B Preferred  Stock,  representing  an  aggregate  face amount of
         $5,250,000,  using  proceeds  from the  issuance  of Series C Preferred
         Stock,  at a 20% premium.  Prior to such date,  the holders of Series B
         Preferred  Stock had converted  419 shares of Series B Preferred  Stock
         into 2,392,220 shares of Common Stock. In February 1998, the holders of
         the Series B  Preferred  Stock had  exercised  an option to require the
         Company to repurchase 351 shares of Series B Preferred Stock, also at a
         20%  premium,  using  proceeds  from the sale of  international  patent
         rights (see Note 6).


                                       9
<PAGE>

         The amount of the  repurchase  price in excess of the carrying value of
         the Series B  Preferred  Stock  repurchased  and a pro rata  portion of
         Series B Preferred  Stock-related  financing  costs  increased the loss
         attributable  to common  shareholders  for the nine month  period ended
         September 30, 1998.

         Issuance of Common Stock

         In July 1998,  the Company  issued  102,798  shares of Common  Stock in
         connection  with its  acquisition  of the  assets of the  Northern  New
         Jersey Eye Institute  (NNJEI) in July 1996. The shares were issuable as
         of July 3, 1998 because the Company's quoted stock price was lower than
         $15.00 per share on that date.  Because the fair value of the  purchase
         consideration  was  determinable  at the  date of  acquisition  and was
         recorded at that time, the entry upon the issuance of the shares was to
         record  the par value of the  shares of Common  Stock  issued  with the
         offset to additional paid-in capital.

NOTE 9   ACQUISITION

         In April 1998,  the Company and  Schwartz  Electro-Optics,  Inc.  (SEO)
         completed an acquisition  whereby the Company  purchased  substantially
         all of the assets,  and assumed certain  liabilities,  of SEO's medical
         products  division (the Division) in exchange for 305,820 shares of the
         Company's Common Stock. The Company is contingently  obligated to issue
         up to  223,280  additional  shares  on April  15,  1999 if its five day
         average  Common Stock price is not then $5.00 or greater.  The value of
         the  acquisition  was  $1,250,000.   The  Division   develops,   tests,
         manufacturers, assembles, and sells lasers and their related equipment,
         accessories,  parts,  and  software  for medical  and medical  research
         applications.  The Division's primary focus is erbium lasers, which are
         primarily used to perform dermatology procedures.

         The   acquisition   was  accounted  for  using  the  purchase   method.
         Accordingly,  the Division's  results of operations are included in the
         Company's   consolidated   financial   statements   subsequent  to  the
         acquisition  date.  The fair value of the  purchase  consideration  was
         determined at the date of acquisition and was recorded at that time. If
         and when the  additional  shares  of Common  Stock are  issued in April
         1999, the entry will be to record the par value of the shares of Common
         Stock with the offset to additional  paid-in  capital.  The acquisition
         did not have a  material  effect  on the  assets or  operations  of the

</TABLE>

Revenue in the third quarter of 1998 was $5,260,614, compared to $6,156,359 (for
a decrease of $895,745) over the same period in 1997. Revenue for the nine-month
period ended September 30, 1998, decreased by $3,630,260 to $14,452,813 from the
same period in 1997.  Technology  revenues  increased  $2,444,003 and $5,585,462
during the three and nine-month periods ended September 30, 1998,  respectively,
compared to the same periods in 1997.  These technology  revenue  increases were
primarily a result of (i) a higher  level of laser system sales during the three
and nine month  periods  ended  September  30,  1998;  (ii) a  fourteen  percent
increase in the average selling price of laser systems  resulting from increased
sales  of  the  Company's  higher-priced  LSX  model  and  fewer  sales  of  the
lower-priced LS-300 model; (iii) an increase in revenues generated from the sale
of service  contracts;  and (iv) revenues generated from royalty payments earned
on  intellectual  property  agreements.  Thirteen laser systems were sold in the
third  quarter of 1998  compared to ten system sales during the third quarter of
1997.  Forty-two  laser  systems  were sold during the nine month  period  ended
September 30, 1998, compared to thirty-three systems sold during the same period
in 1997.

More than  offsetting  the  increases in technology  revenues were  decreases in
health care services  revenue  ($3,339,748 and $9,215,722 for the three and nine
month  periods  ended  September  30, 1998,  respectively,  compared to the same
periods in 1997),  which was  attributable to the sale of MEC and LSIA to Vision
21 in a  transaction  effective as of December 1, 1997.  These two  subsidiaries
contributed   $3,120,298  and  $8,710,401  in  revenues  during  the  three  and
nine-month periods ended September 30, 1997, respectively.  All of the Company's
health care  services  revenue for the first nine months of 1998 was provided by
MRF,  Inc.,  d/b/a The Farris  Group  (TFG).  Net  revenue  for TFG in the third
quarter of 1998 was $138,780  compared to $358,230  (for a decrease of $219,450)
over the same  period in 1997.  This  decrease  was  accompanied  by a  $339,227

<PAGE>


reduction in expenses over the same three-month  period in 1997. Net revenue for
TFG during the nine-month period ended September 30, 1998, was $504,977 compared
to  $1,010,298  (for a decrease of $505,321)  for the same period in 1997.  That
decrease  was  accompanied  by a $709,805  reduction  in expenses  over the same
period in 1997.

gross margin  increase is primarily  attributable to the sale of MEC and LSIA to
Vision  21 in a  transaction  effective  as  of  December  1,  1997.  Those  two

Research, development and regulatory expenses for the third quarter of 1998 were
$923,850,  an increase of $107,328 or 13% from such expenditures during the same
period in 1997. Research, development and regulatory expenses for the nine-month
period ended  September 30, 1998  increased by $756,041 from  $1,729,153 for the
same  period  in  1997,  or 44%.  The  increase  in  research,  development  and
regulatory  expenses during the three and nine month periods ended September 30,
1998,  can primarily be attributed to ongoing  research and  development  of new
scanning refractive laser systems,  including  continued  development of the LSX
and add-on features for the LaserScan 2000, and continued  software  development
for the laser systems.  Additionally,  the Company has incurred  increased costs
related to the FDA regulatory approval process,  both for its own scanning laser
system and the LASIK laser system (for which the Company purchased the rights to
manufacture and  commercialize if FDA approval is received--see  Note 7 of Notes
to Condensed  Consolidated  Financial  Statements).  Additional  costs have been
incurred  in  the  clinical  and  manufacturing   validation  of  the  Automated
Disposable Keratome ("A*D*K"). Since the initial announcement of the development
of the A*D*K and LSX, the Company has solicited and received input from clinical
users and  prospective  customers.  This has  resulted in  modifications  to the
products,   necessitating   additional  development  and  testing  for  clinical
validation.  As a result of a  continuation  of the efforts  described  plus the
anticipated  development of new product ideas,  the Company expects research and
development  expenses  during the remainder of 1998 and 1999 to remain at levels
consistent  with those  incurred  during the third  quarter of 1998.  Regulatory
expenses may increase as a result of the Company's  continuation  of current FDA
clinical trials, protocols added during 1997 related to the potential use of the
Company's laser systems for treatment of glaucoma,  the possible  development of
additional future protocols for submission to the FDA and the LASIK PMA acquired
in July 1997.

Selling  related  expenses  consist  of those  items  directly  related to sales
activities,  including  commissions on sales,  royalty or license fees, warranty
expenses, and costs of shipping and installation.  Commissions and royalties, in

particular,  can  vary  significantly  from  sale to sale or  period  to  period
depending on the location and terms of each sale.

Selling  related  expenses  increased by $798,758 for the third  quarter of 1998
compared to the same  period in 1997.  The  primary  reasons  for this  increase
include a higher  level of laser  system  sales with an  associated  distributor
commission  ($482,000),  a higher  level of royalty fees  ($117,000)  and higher
warranty expenses resulting from increased system sales.

Selling  related  expenses  increased  by  $1,403,702  for the nine months ended
September 30, 1998 compared to the same period in 1997. The primary  reasons for
this  increase  include a higher level of laser system sales with an  associated
distributor commission ($519,000), a higher level of royalty fees ($473,000) and
higher warranty expenses resulting from increased system sales.

Other  General and  Administrative  Expenses.  The  following  tables  present a

</TABLE>

Other general and  administrative  expenses  increased by $493,036 for the third
quarter  of 1998  compared  to the same  period in 1997.  These  increases  were
necessary to fund the strategic  initiatives of the Company and the  development
of its products and services. Such efforts included enhancements to the customer
support,   quality   assurance,   manufacturing   and  engineering   departments
($397,000),  costs  of the  aesthetic  laser  product  acquired  in  April  1998
($218,000)  and bad debt expense  ($212,000).  The total  increase was partially
offset  by the sale of MEC and LSIA  ($491,000)  and a  reduction  in the  other
general and administrative expenses of TFG ($299,000).

Other  general and  administrative  expenses  decreased by $251,182 for the nine
months  ended  September  30, 1998  compared  to the same  period in 1997.  This
decrease  primarily  resulted from the sale of MEC and LSIA  ($1,504,000)  and a
reduction in the other general and  administrative  expenses of TFG  ($619,000).
Such  decreases  were  partially  offset by other  increases,  including  to the
customer support,  quality assurance,  manufacturing and engineering departments
($656,000),  costs  of the  aesthetic  laser  product  acquired  in  April  1998
($424,000),  bad debt expense ($275,000) and patent related expenses ($149,000),
which were nominal before August 1997.

Loss From  Operations.  There was an operating  loss of  $2,373,183 in the third
quarter of 1998 compared to an operating  loss of $2,019,485 for the same period
in 1997,  including TFG's losses (including  goodwill  amortization) of $101,980
and $221,757,  respectively.  The results are  attributed to the sale of MEC and
LSIA,  which  generated  income from  operations  of  $199,052  during the third
quarter of 1997, and the increases in operating expenses  previously  described.


                                       14
<PAGE>

The  operating  loss for the nine month  period  ended  September  30,  1998 was
$5,725,559  compared to an operating  loss of $4,599,316  for the same period in
1997,  including TFG's losses (including goodwill  amortization) of $442,759 and
$647,243  respectively.  The  decrease in  operating  results for the nine month
period ended  September 30, 1998, can be attributed to the sale of MEC and LSIA,
which generated  income from operations of $481,922 during the 1997 period,  and
the increases in operating expenses previously described.  These reductions were
partially offset by the increase in technology generated revenues.

Other Income and Expense. Interest and dividend income was $224,525 in the third
quarter of 1998 compared to interest and dividend income of $94,401 for the same
period in 1997.  Interest  and  dividend  income for the nine month period ended
September  30, 1998 was $450,823  compared to interest  and  dividend  income of
$292,272 for the same period in 1997.  Interest  and dividend  income was earned
from the investment of cash and cash equivalents and the collection of long-term
receivables related to laser system sales.  Interest expense incurred was $1,272
in the third  quarter of 1998  compared to interest  expense of $483,794 for the
same period in 1997.  Interest expense for the nine month period ended September
30, 1998 was  $721,813  compared to  interest  expense of $911,966  for the same
period in 1997.  Interest  expense  incurred by the Company during the three and
nine month  periods ended  September 30, 1998 and 1997 related  primarily to the
credit facility established with Foothill on April 1, 1997 and repaid in full in
June 1998. In addition to interest paid on the outstanding note payable balance,
interest  expense  includes the  amortization of deferred  financing  costs, the
accretion  of the  discount  on the  note  payable,  and  fees  associated  with
amendments to the original loan  agreement.  The Company also recorded a gain on
the sale of investments  and  subsidiaries  resulting from the sale of Vision 21
common stock and MEC and LSIA.

Income  Taxes.  For the three  months  ended  September  30, 1998 and 1997,  the
Company recorded no income tax expense.  For the nine months ended September 30,
1998, the Company recorded income tax expense of $232,213  compared to no income
tax  expense  over the same  period in 1997.  The net expense for the nine month
period is  primarily  the result of  realized  gains and the payment of Japanese
taxes (see Note 6 of Notes to Condensed Consolidated Financial Statements).

Net Loss.  Net loss for the third quarter of 1998 was  $2,149,930  compared to a
net loss of $2,408,878  for the same period in 1997. Net loss for the nine month
period  ended  September  30,  1998,  was  $5,864,310  compared to a net loss of
$5,499,410  for the same period in 1997.  The decrease in net loss for the third
quarter of 1998 can be  attributed  to the  decrease in interest  expense and an
increase  in  technology  revenues,  partially  offset by the higher  technology
operating  expenses and the effect of the sale of MEC and LSIA.  The increase in
net loss for the nine month period ended  September 30, 1998,  can be attributed
the sale of MEC and LSIA,  increases in  research,  development  and  regulatory
expenses,  general and administrative  expenses,  and income tax expense.  These
reductions  were  partially  offset by an increase in technology  revenues and a
decrease in interest expense and gain on sale of investments and MEC and LSIA.

Loss  Attributable to Common  Shareholders.  For the nine months ended September
30, 1998, the Company's loss attributable to common shareholders was impacted by
the following  events,  which occurred in the first and second quarters of 1998:
premiums  paid  on  the  repurchase  of  shares  of  Series  B  Preferred  Stock
($1,752,000), accretion of the financing costs related to such shares ($999,953)
and the value of the conversion  discount on Series B Preferred  Stock ($25,372)
and on Series C Preferred Stock and Series D Preferred Stock ($833,500).

Loss Per Share.  Loss per basic and diluted  share  decreased to ($0.17) for the
third quarter of 1998 compared to ($0.25) for the same period in 1997.  The loss
per basic and diluted share increased to ($0.79) for the nine month period ended
September  30,  1998,  compared to ($0.59)  for the same period in 1997.  Of the
basic and diluted losses per share for the nine month period ended September 30,
1998, ($0.30), was a result of the value of the conversion discount on preferred
stock in accordance with EITF Topic D-60 and accretion and dividend requirements
on the Series B Preferred  Stock.  The weighted  average  shares of Common Stock


                                       15
<PAGE>

outstanding  increased  primarily  due to the  exercise  of  stock  options  and
warrants,  the  conversion  of  Series B  Preferred  stock,  and the  additional
issuance of Common Stock  related to the  acquisition  of the Division from SEO,
the assets of NNJEI,  and to Photomed during the nine months ended September 30,
1998.

Liquidity and Capital Resources.

Working capital  increased  $7,139,830 from  $12,729,700 at December 31, 1997 to
$19,869,530 as of September 30, 1998. This increase in working capital  resulted
primarily  from the private  placement of Series C Preferred  Stock and Series D
Preferred Stock and an increase in trade accounts and notes receivable offset by
accrued commissions. Operating activities used net cash of $9,651,392 during the
first nine months of 1998,  compared to  $2,955,728  of net cash used during the
same period in 1997.  This  increase is  primarily  the result of an increase in
accounts  and notes  receivable  (primarily  the result of slow  collections  of
outstanding  receivables and higher selling prices  resulting from more sales of
the  Company's  LSX system),  increases in  inventory  levels and a  significant
decrease in income taxes  payable,  partially  offset by an increase in deferred
royalty revenue and amortization  and  depreciation  costs. Net cash provided by
investing  activities  during  the first  nine  months  of 1998 was  $11,275,825
compared to $15,247,194 in net cash used in investing  activities  over the same
period in 1997. Net cash provided by investing  activities during the first nine
months  of 1998 can be  primarily  attributed  to  proceeds  generated  from the
exclusive  licensing  of  patents  and from the sale of Vision  21 common  stock
resulting from the Company's December 1997 sale of MEC & LSIA,  partially offset
by the purchase of furniture,  equipment and  leasehold  improvements.  Net cash
provided from financing  activities was $3,789,627  during the first nine months
of 1998, compared to $17,363,579 over the same period in 1997. Net cash provided
from financing activities during the first nine months of 1998 resulted from the
exercise  of stock  options  and  warrants  and net  proceeds  from the Series C
Preferred Stock and Series D Preferred Stock issuances, offset by the repurchase
of Series B Preferred  Stock and the  repayment of the note payable to Foothill.
Net cash provided by financing  activities  during the first nine months of 1997
consisted of net proceeds  from the  issuance of Series B Preferred  Stock,  net
proceeds  from the credit  facility  with  Foothill  and the  exercise  of stock
options,  offset by the  repayment of a note payable to the former owners of MEC
and repayment of a capital lease obligation.

The Company believes that its balances of cash and cash  equivalents  along with
operating cash flows will be sufficient to fund its anticipated  working capital
requirements  for the next  twelve  month  period  based on  modest  growth  and
anticipated timely collection of receivables and entry into the U.S. marketplace
with  keratome  related  products  and/or  the LSX  system.  A failure to timely
collect a material portion of current  receivables or further delays to entering
the  U.S.  market,  could  have a  material  adverse  effect  on  the  Company's
liquidity.  There can be no  assurance  as to the terms or amount of third party
financing, if any, that the Company's customers may obtain in the future.

The Company expects to increase the level of  manufacturing  and distribution of
its  laser  systems  and to  continue  a variety  of  research  and  development
activities  on its excimer and  solid-state  laser  systems over the next twelve
months and it is  anticipated  that such  research  and  development  as well as
regulatory  efforts in the U.S. will be the most significant  technology related
expenses in the foreseeable future.

The Company is receptive to joint venture discussions with compatible  companies
for the further development of international markets for the Company's products.
The Company has no present commitments for joint venture  relationships,  and no
assurance  can be given  that any such  relationships  will be  secured on terms
satisfactory to the Company.

RISK FACTORS AND UNCERTAINTIES

The business,  results or operations and financial  condition of the Company and
the market price of the Common  Stock may be adversely  affected by a variety of
factors,  including  the ones  listed  under the caption  "Risk  Factors" in the
Company's  Registration  Statement on Form S-3/A (file no.  333-59369)  filed on
August 31, 1998, and the additional or updated factors listed below:

Shares Eligible For Future Sale. Except as provided below,  substantially all of
the Company's  outstanding  Common Stock  (13,157,635  shares as of November 13,
1998) is freely tradable without  restriction or further  registration under the
Securities  Act,  unless such shares are held by  "affiliates" of the Company as
that term is defined in Rule 144 under the Securities  Act. The shares of Common
Stock listed below are  "restricted  securities."  Restricted  securities may be
sold in the public market only if they have been registered under the Securities
Act or if their sales qualify for Rule 144 or another  available  exemption from
the registration requirements of the Securities Act.

        o   A  warrant  to  purchase  40,673  shares of  Common  Stock  (with an
            exercise  price  of  $5.81)  has  been  issued  to four  individuals
            associated with its placement agent in connection with the placement
            of the  Series B  Preferred  Stock and  shares  issuable  under such
            warrant (the "Shoreline  Shares") will be freely saleable  following
            such  exercise,  subject  only to the  satisfaction  of a prospectus
            delivery requirement.

        o   Warrants to purchase an aggregate of 762,616  shares of Common Stock
            (with an  exercise  price of $2.71 per share) has been issued to the
            former holders of the Series B Preferred  Stock and shares  issuable
            under such warrant (the "Series B Shares")  will be freely  saleable
            following  such  exercise,  subject  only to the  satisfaction  of a
            prospectus  delivery  requirement.  As of November 13, 1998, 140,625
            such warrants have been exercised.

        o   The 535,515 shares issued in an unregistered acquisition transaction
            in July 1997 (the  "Photomed  Shares") have become freely  tradable,
            subject only to a prospectus delivery requirement.

        o   The 187,500 shares issued in an unregistered acquisition transaction
            in September 1998 (the "Photomed  Amendment Shares") are the subject
            of certain demand and piggyback registration rights.

        o   The 581,825 shares of Common Stock (the "Foothill  Shares") issuable
            upon the exercise  (at an exercise  price of $5.21 per share) of the
            warrants issued to Foothill Capital Corporation ("Foothill") are the
            subject of certain demand and piggyback registration rights.

        o   Other shares of Common Stock (the "Other  Shares") which the Company
            may be  required  to issue in the  future may  become  eligible  for
            resale pursuant to Rule 144, the exercise of registration rights, or
            otherwise.    See    "Possible    Dilutive    Issuance   of   Common
            Stock--LaserSight Centers and Florida Laser Partners; --SEO Medical;
            --Series D Preferred Stock."

Sales, or the possibility of sales,  of the Shoreline  Shares,  Series B Shares,
Photomed Shares,  Photomed  Amendment Shares,  Foothill Shares, or Other Shares,
whether  pursuant to a  prospectus,  Rule 144 or  otherwise,  could  depress the
market price of the Common Stock.

Past and Expected  Future Losses and Operating Cash Flow Deficits;  No Assurance
of Future Profits or Positive  Operating Cash Flows. The Company incurred losses
of $5.9  million for the nine months ended  September  30, 1998 and $7.3 million
and $4.1 million during 1997 and 1996,  respectively.  During such periods,  the
Company  had a deficit  in cash  flow  from  operations  of $9.7  million,  $4.4
million,  and  $4.2  million,   respectively.   Although  the  Company  achieved
profitability  during  1995  and  1994,  it had a  deficit  in  cash  flow  from
operations of $1.9 million during 1995. In addition, the Company incurred losses
in 1991 through 1993. As of September 30, 1998,  the Company had an  accumulated


                                       17
<PAGE>

deficit of $17.7  million.  As a result of the Company's sale of MEC and LSIA in
December 1997, the Company's losses and deficits in cash flow from operations in
future periods may be greater than if the Company had not sold MEC and LSIA. The
Company  expects to report a loss and deficit in cash flow from  operations  for
the fourth  quarter of 1998.  The  Company  recently  resolved  its  outstanding
litigation  with  Mercacorp and expects to record a non-cash  charge to earnings
during the fourth quarter of 1998 equal to the fair value of the warrants issued
to Mercacorp  (approximately  $300,000) in  connection  with  resolution  of the
litigation.  There can be no  assurance  that the  Company can regain or sustain
profitability or positive operating cash flow.

Uncollectible  Receivables  Could Exceed  Reserves.  At September 30, 1998,  the
Company's trade accounts and notes  receivable  aggregated  approximately  $13.6
million net of allowances  for  collection  losses and returns of  approximately
$2.1 million. Accrued commissions, the payment of which generally depends on the
collection  of  such  net  trade  accounts  and  notes  receivable,   aggregated
approximately $2.1 million at September 30, 1998.  Exposure to collection losses
on  receivables  is principally  dependent on the Company's  customer's  ongoing
financial  condition and their  ability to generate  revenues from the Company's
laser  systems.  In addition,  approximately  94% and 90% of net  receivables at
September 30, 1998 and December 31, 1997, respectively, related to international
accounts.  The Company's ability to evaluate the financial condition and revenue
generating  ability of its  prospective  customers  located  outside of U.S.  is
generally  more  limited  than for  customers  located in the U.S.  Although the
Company  monitors  the status of its  receivables  and  maintains  a reserve for
estimated  losses,  there can be no assurance  that the  Company's  reserves for
estimated  losses  (approximately  $1.9 million at  September  30, 1998) will be
sufficient  to  cover  actual  write-offs  over  time.  Actual  write-offs  that
materially  exceed amounts  reserved could have a material adverse effect on the
Company's consolidated financial condition and results of operations.

Restructuring   of   Receivables.   At  September  30,  1998,  the  Company  had
restructured  laser customer  accounts in the aggregate  amount of approximately
$963,466 (7% of the net receivables as of such date), resulting in the extension
of the  original  payment  terms by periods  ranging  from 12 to 60 months.  The
Company's  liquidity  and  operating  cash  flow may be  adversely  affected  if
additional  extensions  become necessary in the future.  In addition,  it may be
more  difficult to collect  laser  system  receivables  if the payment  schedule
extends beyond the expected economic life of the laser system.

Potential Liquidity Problems.  During the three months ended September 30, 1998,
the Company  experienced  a $2.5  million  deficit in cash flow from  operations
largely  resulting  from the loss  incurred  during the period and  increases in
inventory and receivables, partially offset by depreciation and amortization and
increases  in  liabilities.  Of  this  amount,  the  Company  expects  that  any
improvements  in cash flow from  operations  will depend on, among other things,
the Company's  ability to market,  produce and sell its new LSX laser systems in
larger  quantities  and its A*D*K  product on a commercial  basis.  In the third
quarter of 1998, the LSX laser system  represented  the majority of systems sold
and is  expected  to  make  a more  significant  contribution  to the  Company's
operating results in the future.  Based on the status of clinical validation and
refinement  of  the  manufacturing   processes,  the  Company  does  not  expect
significant  commercial  shipments  of the A*D*K in the fourth  quarter of 1998.
Subject to these  factors,  the Company  believes  that its balances of cash and
cash  equivalents,  will be sufficient to fund its  anticipated  working capital
requirements for a 12-month period based on modest growth and anticipated timely
collection  of  receivables  and entry into the U.S.  marketplace  with keratome
related products and/or the LSX system. However, if the Company does not collect
a material portion of current  receivables in a timely manner, or if the Company
experiences  significant further delays in the shipment of its A*D*K product, or
experiences  less  market  demand  for its  products  than it  anticipates,  the
Company's liquidity could be materially adversely affected.

Uncertainty  Regarding  Availability  or Terms of Capital  to  Satisfy  Possible
Additional Needs. The Company may need additional capital, including to fund the
following:

        o   Any future negative cash flow from operations.


                                       18
<PAGE>

        o   Certain  cash  payment  obligations  under the  Company's  LASIK PMA
            application  acquisition  agreement  of July 1997 with  Photomed  as
            amended in September 1998. Such contingent cash payment  obligations
            are  outlined  in  Note 7 in the  Notes  to  Condensed  Consolidated
            Financial Statements.

        o   Additional  working  capital  necessary to develop a production line
            for the LASIK laser system and to obtain the GMP (Good Manufacturing
            Practices)   clearance  from  the  FDA  that  is  required  for  the
            commercial sale of the LASIK laser system.

        o   Additional  working  capital  necessary  to support  the  commercial
            introduction  of its laser  systems  into the U.S.  market  upon FDA
            approval.  (The Company began  incurring such expenses in the second
            half of 1998.)

        o   Additional  working  capital  necessary  to more fully  develop  the
            Company's  mobile  refractive laser business plan and other possible
            business lines and products.

In  addition,  the Company may seek  alternative  sources of capital to fund its
product development activities and to consummate future strategic  acquisitions.
The Company has no commitments from third parties to supply additional  capital,
and there can be no assurance  as to whether or on what terms the Company  could
obtain additional capital.

To the extent  that the  Company  satisfies  its future  financing  requirements
through the sale of equity  securities,  holders of Common Stock may  experience
significant dilution in earnings per share and in net book value per share. Such
dilution may be more  significant  if the Company  sells Common Stock at a price
below  current  market  prices  or  sells  additional  preferred  stock  with  a
conversion  price  linked to the market price of the Common Stock at the time of
conversion.  Debt  financing  could  result  in a  substantial  portion  of  the
Company's cash flow from operations  being dedicated to the payment of principal
and interest on such  indebtedness and may render the Company more vulnerable to
competitive  pressures and economic  downturns.  If the Company needs but cannot
obtain  additional  capital on  satisfactory  terms,  it may be required to sell
additional assets.

Possible Dilutive Issuance of Common Stock--LaserSight Centers and Florida Laser
Partners.  Based  on  previously-reported  agreements  entered  into  in 1993 in
connection with the Company's  acquisition of LaserSight  Centers (the Company's
development-stage  subsidiary)  and  modified in July 1995 and March  1997,  the
Company is obligated as follows:

        o   To issue to the former  stockholders  and option holders  (including
            two trusts  related to the  Chairman of the Board of the Company and
            certain former  officers and directors of the Company) of LaserSight
            Centers, up to 600,000 unregistered shares of Common Stock ("Centers
            Contingent  Shares") based on the Company's pre-tax operating income
            through March 2002 from utilizing a fixed or mobile excimer laser to
            perform   photorefractive   keratectomy  (PRK),  arranging  for  the
            delivery of PRK or receiving license or royalty fees associated with
            patents held by LaserSight  Centers.  The Centers  Contingent Shares
            are  issuable  at the rate of one share per $4.00 of such  operating
            income.

        o   To pay to a partnership  whose partners  include the Chairman of the
            Board of the Company and certain  former  officers and  directors of
            the  Company a royalty  of up to $43  (payable  in cash or shares of
            Common  Stock  ("Royalty  Shares")),  for each  eye on which  PRK is
            performed  on a fixed  or  mobile  excimer  laser  system  owned  or
            operated by LaserSight  Centers or its affiliates.  Royalties do not
            begin to accrue  until the earlier of March 2002 or the  delivery of
            all of the 600,000 Centers Contingent Shares.

                                       19
<PAGE>

As of November 13,  1998,  the Company had not accrued any  obligation  to issue
Centers Contingent Shares or Royalty Shares.  There can be no assurance that any
issuance of Centers  Contingent  Shares or Royalty Shares will be accompanied by
an increase in the Company's  per share  operating  results.  The Company is not
obligated  to pursue  strategies  that may  result in the  issuance  of  Centers
Contingent  Shares or Royalty Shares.  It may be in the interest of the Chairman
of the Board for the Company to pursue  business  strategies  that  maximize the
issuance of Centers Contingent Shares and Royalty Shares.

Possible  Dilutive  Issuance of Common  Stock--Photomed.  If the FDA  approves a
LaserSight-manufactured laser system for general commercial use in the treatment
of  hyperopia  (farsightedness),  utilizing  part or all of the  know-how of the
laser acquired from Photomed,  the Company would be required to issue additional
shares of Common Stock with a market  value of up to $1.0 million  (based on the
average closing price of the Common Stock during the preceding 10-day period) to
the former Photomed stockholders. Such obligation will decrease by approximately
$2,740 per day  beginning  June 1, 1999 if such approval is not received by that
date, and will be eliminated  entirely on June 1, 2000. If such market value had
been computed as of November 16, 1998, the number of additional  shares issuable
would have been approximately 222,000.  Depending on whether and when such FDA
approval is received  and on the market price of the Common Stock at the time of
any such  approval,  the  actual  number of  additional  shares of Common  Stock
issuable could be more (but not more than  permitted  under the listing rules of
The NASDAQ Stock Market) or less than this number.

Possible  Dilutive  Issuance  of  Common  Stock--SEO.  In  connection  with  the
acquisition  of certain assets of SEO in April 1998, the Company agreed to issue
up to 223,280  additional  shares of Common  Stock if the average of the bid and
ask prices of Common Stock for the five trading day period  immediately prior to
April 15, 1999 is less than $5.00 per share.  All 223,280 shares of Common Stock
will be issuable unless such price is more than $2.36 per share.

Possible Dilutive Issuance of Common Stock--Foothill Warrant. In April 1996, the
Company issued to Foothill a warrant to purchase  500,000 shares of Common Stock
(the "Foothill Warrant") at a price of $6.067 per share. The Company is required
to make  anti-dilution  adjustments to both the number of warrant shares and the
warrant  exercise  price in the event the Company  sells  Common Stock or Common
Stock-equivalents  (such as  convertible  securities or warrants) at a price per
share that is (or could be) less than the fair market  value of the Common Stock
at the time of such  sale.  In  connection  with its sale of Series B  Preferred
Stock in August 1997 and  subsequent  conversion of such  preferred  shares into
Common  Stock,  the  sale of the  Series  C  Preferred  Stock  and the  Series D
Preferred Stock such anti-dilution  adjustments have resulted in (i) an increase
in the number of Foothill Warrant shares to 581,825, and (ii) a reduction to the
exercise  price of the Foothill  Warrant  shares to $5.21 per share.  Additional
anti-dilution  adjustments  to the Foothill  Warrant  could also result from any
future below-market sales of Common Stock by the Company.

Possible Dilutive Issuance of Common Stock--Series B Warrant. In connection with
its sale of the Series B Preferred  Stock in August 1997,  the Company issued to
the former holders of the Series B Preferred Stock warrants to purchase  750,000
shares of Common Stock (the "Series B Warrant") at a price of $5.91 per share at
any time before  August 29,  2002.  In  connection  with a March 1998  agreement
whereby the Company  obtained  the option to  repurchase  the Series B Preferred
Stock and a lock-up on  conversions,  the exercise price of the Series B Warrant
shares  was  reduced  to $2.753  per share.  The  Company  is  required  to make
anti-dilution  adjustments  to both the number of warrant shares and the warrant
exercise   price  in  the  event  the  Company  sells  Common  Stock  or  Common
Stock-equivalents  (such as  convertible  securities or warrants) at a price per
share that is (or could be) less than the fair market  value of the Common Stock
at the time of such  sale.  As a result of the  Company's  sale of the  Series C
Preferred Stock and the Series D Preferred Stock such anti-dilution  adjustments
and other  agreements  among the former holders of the Series B Preferred  Stock
and the  Company  have  resulted  in (i) an  increase  in the number of Series B
Warrant shares to  approximately  762,616,  and (ii) a reduction to the exercise
price of Series B Warrant shares to  approximately  $2.71 per share.  Additional


                                       20
<PAGE>

anti-dilution  adjustments  to the Series B Warrants  could also result from any
future  below-market  sales of Common Stock by the  Company.  As of November 13,
1998, 140,625 of such warrants had been exercised.
                            
Possible Dilutive  Issuance of Common  Stock--Shoreline  Warrant.  In connection
with its sale of the Series B Preferred Stock in August 1997, the Company issued
to four  individuals  associated  with its placement  agent warrants to purchase
40,000 shares of Common Stock (the "Shoreline  Warrant") at a price of $5.91 per
share at any time  before  August 29,  2002.  The  Company is  required  to make
anti-dilution  adjustments  to both the number of warrant shares and the warrant
exercise   price  in  the  event  the  Company  sells  Common  Stock  or  Common
Stock-equivalents  (such as  convertible  securities or warrants) at a price per
share that is (or could be) less that the fair market  value of the Common Stock
at the time of such sale. In connection  with the Company's sale of the Series C
Preferred Stock and the Series D Preferred Stock such anti-dilution  adjustments
have  resulted in (i) an increase in the number of Shoreline  Warrant  shares to
approximately  40,673,  and (ii) a reduction to the exercise  price of Shoreline
Warrant  shares to  approximately  $5.81  per  share.  Additional  anti-dilution
adjustments  to the  Shoreline  Warrants  could  also  result  from  any  future
below-market sales of Common Stock by the Company.

Possible  Dilutive  Issuance  of Common  Stock--Series  D  Preferred  Stock.  In
accordance  with  the  terms  of  the  Company's   Certificate  of  Designation,
Preferences  and  Rights of the Series D  Preferred  Stock,  the  holders of the
Series D Preferred  Stock are entitled to certain  anti-dilution  adjustments if
the  Company  issues  its  Common  Stock or  Common  Stock-equivalents  (such as
convertible securities or warrants) at a price per share (or having a conversion
or exercise price per share) less than $4.00 per share.

Acquisition- and  Financing-Related  Contingent  Commitments to Issue Additional
Common Shares. The Company may from time to time include in future  acquisitions
and financings,  provisions  that would require the Company to issue  additional
shares of its Common  Stock at a future  date  based on the market  price of the
Common Stock at such date.  Persons who are the beneficiaries of such provisions
effectively  receive some  protection  from  declines in the market price of the
Common  Stock,  but other  stockholders  of the  Company  will incur  additional
dilution of their  ownership  interest in the event of a decline in the price of
the Common Stock. Such dilution may be increased by the anti-dilution protection
provisions  in the  Foothill  Warrant,  the Series B Warrant  and the  Shoreline
Warrant  that may  increase  the  number of shares  issuable  under each of such
warrants and decrease the  exercise  price of such  warrants.  The factors to be
considered by the Company in including such provisions may include the Company's
cash resources, the trading history of Common Stock, the negotiating position of
the selling party or the investors,  as applicable,  and the extent to which the
Company  estimates that the expected  benefit from the  acquisition or financing
exceeds the expected dilutive effect of the price-protection provision.

Dependence on Key Personnel.  The Company is dependent on its executive officers
and other key employees,  especially  Michael R. Farris, its President and Chief
Executive  Officer,  and J. Richard  Crowley,  the President and Chief Operating
Officer of the Company's LaserSight  Technologies  subsidiary.  A loss of one or
more such officers or key  employees,  especially of Mr. Farris or Mr.  Crowley,
could have a material adverse effect on the Company's business. The Company does
not carry "key man" insurance on Mr.  Farris,  Mr. Crowley or any other officers
or key employees.

As the Company  continues  the clinical  development  of its excimer  lasers and
other products and prepares for regulatory approvals and other commercialization
activities,  it will need to continue to implement  and expand its  operational,
financial and management  resources and controls.  The failure of the Company to
attract and retain experienced  individuals for necessary positions,  as well as
any  inability of the Company to  effectively  manage growth in its domestic and
international  operations  could have a material adverse effect on the Company's
business, financial condition and results of operations.

Risks  Associated  with Past and Possible Future  Acquisitions.  The Company has
made  several  significant  acquisitions  since  1994,  including  TFG in  1994,
Photomed in 1997 and 1998,  the patents  purchased from  International  Business
Machines  Corporation in August 1997 and its acquisition of SEO Medical in April
1998. These  acquisitions,  as well as any future  acquisition,  may not achieve


                                       21

<PAGE>

adequate levels of revenue,  profitability  or productivity or may not otherwise
perform as expected. Acquisitions involve special risks, including unanticipated
liabilities and  contingencies,  diversion of management  attention and possible
adverse  effects  on  operating  results   resulting  from  increased   goodwill
amortization,  increased  interest costs, the issuance of additional  securities
and difficulties related to the integration of the acquired businesses. Although
the Company is currently focusing on its existing operations, the future ability
of the Company to achieve growth through acquisitions will depend on a number of
factors, including the availability of attractive acquisition opportunities, the
availability  of funds  needed to complete  acquisitions,  the  availability  of
working  capital  needed to fund the  operations of acquired  businesses and the
effect of existing and emerging  competition  on operations.  Should  additional
acquisitions be sought,  there can be no assurance that the Company will be able
to successfully  identify additional suitable acquisition  candidates,  complete
additional acquisitions or integrate acquired businesses into its operations.

Amortization of Significant  Intangible Assets. Of the Company's total assets at
September 30, 1998, approximately $16.9 million (34%) were intangible assets, of
which  approximately  $6.7 million  reflects  goodwill (which is being amortized
using an estimated life ranging from 12 to 20 years), approximately $4.5 million
reflects the cost of patents  (which is being  amortized  over a period  ranging
from  approximately 8 to 17 years),  and approximately $5.7 million reflects the
cost of acquired licenses and technology (which is being amortized over a period
ranging from 31 months to 12 years). The 12-year life of acquired technology was
determined  based on the Company's  best judgment at the time of the most likely
life span of a solid-state  laser product and related patent.  The major factors
involved in the Company's ongoing assessment are its judgment whether there will
be a  market  for  solid-state  as an  improvement  to  existing  excimer  laser
technology  and that  there is an  industry  and  marketplace  interest  in such
development that can be successfully  pursued by the Company or others that will
result in revenue from the associated  patent.  Goodwill is an intangible  asset
that  represents  the  difference  between  the  total  purchase  price  of  the
acquisitions  and the amount of such purchase price  allocated to the fair value
of the net assets acquired.  Goodwill and other intangibles are amortized over a
period of time, with the amount amortized in a particular period  constituting a
non-cash  expense  that  reduces  the  Company's  net income (or  increases  the
Company's net loss) in that period. A reduction in net income resulting from the
amortization  of goodwill and other  intangibles may have an adverse impact upon
the market price of the Common  Stock.  In  addition,  in the event of a sale or
liquidation  of the Company or its assets,  there can be no  assurance  that the
value of such intangible assets would be recovered.

In  accordance  with  SFAS  121,  the  Company  reviews  intangible  assets  for
impairment  whenever events or changes in circumstances,  including a history of
operating or cash flow losses, indicate that the carrying amount of an asset may
not be recoverable.  In such cases, the carrying amount of the asset is compared
to the estimated  undiscounted future cash flows expected to result from the use
of  the  asset  and  its  eventual  disposition.  If the  sum  of  the  expected
undiscounted future cash flows is less than the carrying amount of the asset, an
impairment  loss will be computed and  recognized in  accordance  with SFAS 121.
Expected cash flows are based on factors including  historical results,  current
operating  budgets  and  projections,  industry  trends  and  expectations,  and
competition.

The Company  continues to assess the current results and future prospects of TFG
in view of the substantial  reduction in the subsidiary's  operating  results in
1996 and 1997. TFG's operation  results have improved in 1998 from 1996 and 1997
performance.  If TFG is  unsuccessful  in  continuing  to improve its  financial
performance, some or all of the carrying amount of goodwill recorded ($3,790,000
at September 30, 1998) may be subject to an impairment adjustment.

Year  2000  Compliance.  The  company  understands  the  material  nature of the
business  issues  surrounding  computer  processing of dates into and beyond the
Year 2000 ("Y2K"). Any computer program or computer chip controlled device could
harbor a Y2K  processing  issue.  Typically,  Y2K issues  arise from  systems or
software  processing only two digits representing a date. The century digits, if
not present  ("19" for years  1900-1999,  or "20" for years  beginning in 2000),
usually lead to false results from computer  controlled systems and are the most
pervasive issue.

                                       22

<PAGE>

The Company  recognizes that these issues exist within its computer programs and
computer chip controlled  devices and is taking corrective action. The Company's
actions to address Y2K issues began with the development of a comprehensive plan
to assess the actual and potential impact of the issues on the Company,  both in
information  technology ("IT") areas and non-information  technology  ("Non-IT")
areas,  which include its  manufacturing and operating systems and the readiness
of vendors and other third parties upon whom the Company relies.

The  Company's  IT systems  are  microcomputer-based  and  consist  of  standard
software  purchased from outside  vendors.  All software is being identified and
assessed  to  determine  the extent of  remediation  required in order to be Y2K
compliant.  The Company  believes  that all software  will be made Y2K compliant
before the end of June 1999 through  vendor-provided updates or replacement with
other Y2K compliant hardware and software.  The Company, as has been planned for
some time, is also replacing its financial and accounting software,  and expects
to have the  majority  of such new  software  implemented  by the end of January
1999. Such software has been represented to be Y2K compliant by the vendors. The
Company's IT inventory  related to Y2K compliance is approximately 50% complete,
the remediation  assessment of problem areas is approximately 25% complete,  and
testing,  including  validation of  compliance,  is expected to begin in January
1999 and be completed by the end of April 1999.

For its Non-IT  systems,  the  Company is in the  process of  identifying  third
parties with which it has a significant relationship that, in the event of a Y2K
failure,  could have a material  impact on the Company's  financial  position or
operating  results.  The third parties include utility  suppliers,  material and
supply   vendors,   communication   vendors   and  the   Company's   significant
distributors.  Some of these  relationships,  especially  those  associated with
certain  suppliers  and  distributors,  are  material  to the  Company and a Y2K
failure  by one or more of these  parties  could  result in a  material  adverse
effect on the Company's operating results and financial position. The Company is
corresponding with these business partners and service providers to assess their
ability to support the Company's operations with respect to their individual Y2K
issues.  The  issues  that  are  identified  as  part of  this  process  will be
prioritized in order of significance to the Company's  operations and corrective
action taken as appropriate.  The Company estimates that correspondence has been
initiated with approximately 90% of the Company's vendors, business partners and
service providers.  Approximately 40% have responded to date, and the Company is
in the process of  assessing  their  responses.  The Company  expects  that this
process will continue throughout the current and subsequent fiscal year.

For Y2K issues which, if not timely resolved, could have a significant impact on
the Company's  operations,  the Company  intends to develop  contingency  plans.
Those plans will be  designed  to minimize  the impact of failure to achieve Y2K
compliance.  Such  contingency  plans are expected to be developed by the end of
March 1999.

The Company estimates that costs to address Y2K issues will total  approximately
$150,000,  of which approximately  $20,000 has been incurred to date. Such costs
will be  expensed  as  incurred,  and  exclude  the costs of the  Company's  new
financial and accounting software. Y2K compliance related costs are estimated to
be approximately 50% of the Company's total IT expense budget through the end of
1999. No material IT projects are expected to be delayed.

Due to the general uncertainty inherent in the Company's Y2K compliance,  mainly
resulting  from  the  Company's  dependence  upon  the  Y2K  compliance  of  the
government agencies,  suppliers,  vendors and distributors with whom the Company
and its service  providers deal, the Company is unable to determine at this time
its most reasonably likely worst case scenario.  While costs related to the lack
of Y2K compliance of third parties, business interruptions, litigation and other
liabilities  related to Y2K issues could  materially  and  adversely  affect the
company's business,  results of operations and financial condition,  the Company
expects its Y2K compliance  efforts to reduce  significantly the Company's level
of uncertainty  about the impact of Y2K issues  affecting both its IT and Non-IT
systems.

                                       23

Government  Regulation.  The  Company's  laser  products  are  subject to strict
governmental  regulations  which  materially  affect  the  Company's  ability to
manufacture and market these products and directly impact the Company's  overall
prospects.  All laser devices to be marketed in interstate  commerce are subject
to the laser regulations required by the Radiation Control for Health and Safety
Act,  as  administered  by the FDA.  Such Act  imposes  design  and  performance
standards,  labeling and reporting  requirements,  and submission  conditions in
advance of marketing for all medical laser products. The Company's laser systems
produced  for medical use require PMA approval by the FDA before the Company can
ship its laser systems for use in the U.S. Each separate medical device requires
a separate FDA  submission,  and specific  protocols have to be submitted to the
FDA for each claim made for each medical device.

If and when the  Company's  laser  systems  receive PMA approval by the FDA, the
Company  will  be  required  to  obtain  GMP  clearance   with  respect  to  its
manufacturing  facilities.  These  regulations  impose  certain  procedural  and
documentation  requirements  upon the Company with respect to its  manufacturing
and quality assurance  activities.  The Company's  facilities will be subject to
inspections  by the FDA, and if any  noncompliance  with GMP guidelines is noted
during facility  inspections,  the marketing of the Company's laser products may
be  adversely  affected.  In  addition,  if any of the  Company's  suppliers  of
significant components or sub-assemblies cannot meet the quality requirements of
the Company,  the Company could be delayed in producing  commercial  systems for
the U.S.
market.

Additionally,  product  and  procedure  labeling  and all  forms of  promotional
activities are subject to  examination  by the FDA, and current FDA  enforcement
policy  prohibits the marketing of approved medical devices for unapproved uses.
Noncompliance  with these  requirements  may result in warning  letters,  fines,
injunctions, recall or seizure of products, suspension of manufacturing,  denial
or withdrawal of PMAs, and criminal prosecution.

Laser  products  marketed in foreign  countries  are often subject to local laws
governing health product development processes which may impose additional costs
for overseas  product  development.  In particular,  all member countries of the
European Economic Union ("EU") require CE Mark  certification of compliance with
the EU medical  directives as the standard for  regulatory  approval for sale of
laser systems in EU member countries.  Both the Company's LSX and LaserScan 2000
laser  systems  have  received  CE Mark  certification,  the former of which was
received in September 1998.

The Company  cannot  determine  the costs or time it will take to  complete  the
approval  process  and  the  related  clinical  testing  for its  medical  laser
products.  Future  legislative or  administrative  requirements  in the U.S., or
elsewhere,  may  adversely  affect  the  Company's  ability  to obtain or retain
regulatory  approval  for its laser  products.  The  failure to obtain  required
approvals  on a  timely  basis  could  have a  material  adverse  effect  on the
Company's business, financial condition and results of operations.

Uncertainty  Concerning  Patents--International.  Should  the  Company's  lasers
infringe upon any valid and enforceable patents in international  markets,  then
the Company may be required to obtain  licenses  for such  patents.  Should such
licenses not be  obtained,  LaserSight  Technologies  might be  prohibited  from
manufacturing  or marketing its excimer lasers in those  countries where patents
are in effect.  The  Company's  international  sales  accounted for 88% and 42%,
respectively,  of the  Company's  total  revenues  during the nine months  ended
September  30, 1998 and 1997,  respectively.  In the  future,  until the Company
receives  necessary  regulatory  approvals  and enters the U.S.  market (or with
respect to those  products that do not require  regulatory  approval,  otherwise
enters the U.S.  market) in a  significant  way with its  products,  the Company
expects its percentage of international sales to be more comparable to the sales
percentages which were reported for the nine months ended September 30, 1998.

Uncertainty Concerning  Patents--U.S.  Two of the Company's competitors,  Summit
Technology,  Inc. ("Summit") and Visx, Inc. ("Visx") formed a U.S.  partnership,
Pillar  Point  Partners  ("Pillar  Point"),  in 1992 to pool  certain  of  their
respective patents related to corneal sculpting  technologies.  On June 9, 1998,
Summit and Visx announced that they had reached  agreement on the dissolution of


                                       24
<PAGE>

Pillar Point to be effected as soon as possible.  As a part of this dissolution,
Summit and Visx  granted  each other a  worldwide,  royalty  free  cross-license
whereby each party will have full rights to license all existing  patents  owned
by  either  company  relating  to laser  vision  correction  for use with  their
systems.
                                  
Should the Company's lasers infringe upon any valid and enforceable patents held
by Visx or Summit in the U.S.,  then the  Company  may be  required  to obtain a
license for such patents and pay  royalties  and per  procedure  fees to Visx or
Summit for all revenues  generated in the U.S. If such licenses are required but
not obtained,  the Company might be prohibited from  manufacturing  or marketing
its excimer lasers in the U.S. In connection  with its March 1996  settlement of
litigation with Pillar Point Partners, the Company agreed to notify Pillar Point
Partners before the Company begins manufacturing or selling its laser systems in
the U.S.  As of this date,  the  Company has not  obtained a U.S.  license  from
either of Summit or Visx,  and the actual per  procedure  fee and other terms of
any license, if such license is granted, have yet to be determined.

In addition,  there may be other U.S. and foreign  patents for which the Company
will  need to  negotiate  licenses  in order to sell,  lease or use the  excimer
lasers in certain  markets.  There can be no  assurance  that the Company or its
customers  will be  successful  in securing  licenses,  including  any necessary
licenses from Summit or Visx, or that if the Company does obtain licenses,  such
licenses  will be on terms  acceptable  to the  Company.  The  failure to either
obtain required licenses or to obtain licenses on terms favorable to the Company
could have a material adverse effect on the business of the Company.

Competition.  The vision correction  industry is subject to intense,  increasing
competition.  The Company  competes  against both  alternative  and  traditional
medical  technologies (such as eyeglasses,  contact lenses and radial keratotomy
(RK) and other  laser  manufacturers.  Many of the  Company's  competitors  have
existing   products  and  distribution   systems  in  the  marketplace  and  are
substantially  larger,  better  financed,  and better known.  A number of lasers
manufactured  by other  companies  have  either  received,  or are much  further
advanced in the process of receiving, FDA approval for specific procedures, and,
accordingly,  may have or develop a higher level of  acceptance  in some markets
than the Company's lasers. The entry of new competitors into the markets for the
Company's  products could cause downward pressure on the prices of such products
and a material  adverse effect on Company's  business,  financial  condition and
results of operations.

Technological  Change.  Technological  developments  in the  medical  and  laser
industries  are  expected to continue at a rapid pace.  Newer  technologies  and
surgical  techniques could be developed which may offer better  performance than
the Company's  laser systems.  The success of any competing  alternatives to PRK
and LASIK  could  have a  material  adverse  effect on the  Company's  business,
financial condition and results of operations.

New Products.  The Company may experience  difficulties that could further delay
or  prevent  the  successful  development,  introduction  and  marketing  of its
recently-announced  A*D*K, and other new products and enhancements,  or that its
new products and enhancements will be accepted in the marketplace. As is typical
in the case of new and rapidly evolving industries, demand and market acceptance
for  recently-introduced  technology and products are subject to a high level of
uncertainty. In addition, announcements of new products (whether for sale in the
near  future or at some  later  date) may cause  customers  to defer  purchasing
existing Company products.

Minimum  Payments  Under  A*D*K  License  Agreement.  In  addition  to the risks
relating to the  introduction of any new product (see "--New  Products"  above),
the Company's  A*D*K is subject to the risk that the Company is required to make
certain minimum  payments to the licensors under its limited  exclusive  license
agreement relating to the A*D*K.  Under that agreement,  the Company is required
to pay a total of $300,000 in two  installments  due six and 12 months after the
date of the  Company's  receipt of completed  limited  production  molds for the
A*D*K and provide an excimer  laser (such laser was provided  during the quarter
ended June 30,  1998).  The  Company  expects to receive  such molds  during the


                                       25
<PAGE>

fourth  quarter of 1998. In addition,  commencing  seven months after such date,
the  Company's  royalty  payments  (50% of its defined  gross profits from A*D*K
sales) will become  subject to a minimum of $400,000 per calendar  quarter for a
period of eight quarters.
                                  
Uncertainty  of Market  Acceptance of  Laser-Based  Eye  Treatment.  The Company
believes that its  achievement of  profitability  and growth will depend in part
upon broad acceptance of PRK or LASIK in the U.S. and other countries. There can
be  no   assurance   that  PRK  or  LASIK  will  be   accepted   by  either  the
ophthalmologists or the public as an alternative to existing methods of treating
refractive  vision  disorders.  The  acceptance of PRK and LASIK may be affected
adversely  by their cost,  possible  concerns  relating to safety and  efficacy,
general  resistance to surgery,  the effectiveness and lower cost of alternative
methods  of  correcting  refractive  vision  disorders,  the  lack of  long-term
follow-up data, the possibility of unknown side effects, the lack of third-party
reimbursement for the procedures,  any future  unfavorable  publicity  involving
patient outcomes from use of PRK or LASIK systems, and the possible shortages of
ophthalmologists  trained  in the  procedures.  The  failure  of PRK or LASIK to
achieve  broad market  acceptance  could have a material  adverse  effect on the
Company's business, financial condition and results of operations.

International  Sales.  International  sales may be limited or  disrupted  by the
imposition  of  government  controls,  export  license  requirements,  political
instability,  trade restrictions,  changes in tariffs,  difficulties in staffing
and coordinating  communications  among and managing  international  operations.
Additionally,  the Company's  business,  financial  condition and  international
results of  operations  may be  adversely  affected by  increases in duty rates,
difficulties  in  obtaining  export  licenses,  ability to  maintain or increase
prices,  and  competition.  To date,  all sales  made by the  Company  have been
denominated in U.S.  dollars.  Therefore,  the Company does not have exposure to
typical foreign currency fluctuation risk. Due to its export sales, however, the
Company is subject to currency  exchange rate  fluctuations in the U.S.  dollar,
which could  increase the effective  price in local  currencies of the Company's
products.  This could in turn result in reduced sales, longer payment cycles and
greater  difficulty in collection of  receivables.  See  "--Receivables"  above.
Although  the Company has not  experienced  any material  adverse  effect on its
operations as a result of such  regulatory,  political and other  factors,  such
factors may have a material  adverse  effect on the Company's  operations in the
future or require the Company to modify its business practices.

Potential Product Liability Claims; Limited Insurance.  As a producer of medical
devices,  the Company may face liability for damages to users of such devices in
the event of product failure. The testing and use of human care products entails
an inherent risk of negligence or other action. An award of damages in excess of
the Company's  insurance  coverage  could have a material  adverse effect on the
Company's  business,  financial  condition and results of operations.  While the
Company maintains product  liability  insurance,  there can be no assurance that
any such liability of the Company will be included within its insurance coverage
or that  damages  will not  exceed  the limits of its  coverage.  The  Company's
"claims made" product liability insurance coverage is limited to $10 million and
its general liability insurance coverage is limited to $6 million,  including up
to $5 million of coverage under an excess liability  policy.  The Company has in
the past  agreed,  and is likely in the future to agree,  to  indemnify  certain
medical  institutions and personnel thereof  conducting and participating in the
Company's clinical studies.

Supplier Risks. The Company contracts with third parties for certain  components
used in its lasers.  Certain key components are provided by a single vendor.  If
any of these  sole-source  suppliers were to cease  providing  components to the
Company,  the  Company  would  have to locate  and  contract  with a  substitute
supplier,  and there can be no assurances that such substitute supplier could be
located and qualified in a timely manner or could provide required components on
commercially  reasonable  terms. An interruption in the supply of critical laser
components  could  have a material  adverse  effect on the  Company's  business,
financial condition and results of operations.

No  Backlog;  Concentration  of  Sales  at  End  of  Quarter.  The  Company  has
historically  operated  with  little or no  backlog  because  its  products  are


                                       26
<PAGE>

generally shipped as orders are received. Historically, the Company has received
and shipped a  significant  portion of its orders for a particular  quarter near
the end of the quarter.  As a result,  the Company's  operating  results for any
quarter often depend on orders  received and laser systems  shipped late in that
quarter.  Any  delay  in such  orders  or  shipments  may  cause  a  significant
fluctuation in period-to-period operating results.
                                     
Anti-takeover  Measures;  Potential  Adverse  Effect on Common Stock Price.  The
Company's  Certificate  of  Incorporation  authorizes  the  Company's  Board  of
Directors to issue shares of the Company's  Preferred Stock and to determine the
rights, preferences, privileges and restrictions of such shares without any vote
or action by the  stockholders.  The  issuance  of  Preferred  Stock  under such
circumstances  could  have the  effect of  delaying  or  preventing  a change in
control of the  Company.  The rights of the holders of the Common  Stock will be
subject to, and may be  adversely  affected by, the rights of the holders of any
Preferred  Stock that may be created and issued in the future.  On July 2, 1998,
the Company  adopted a  stockholder  rights  agreement  and  declared a dividend
distribution of one Preferred Share Purchase Right ("Right") on each outstanding
share of the Company's  Common Stock.  The Rights will be exercisable  only if a
person or group (other than certain exempt persons)  acquires 15% or more of the
Company's Common Stock. One of the effects of the provisions described above may
be to discourage a future attempt to acquire  control of the Company that is not
presented to and  approved by the Board of  Directors,  but which a  substantial
number, and perhaps even a majority of the Company's stockholders, might believe
to be in  their  best  interests  or  in  which  stockholders  might  receive  a
substantial  premium  for their  shares  over the current  market  prices.  As a
result,  stockholders  who might desire to participate in such a transaction may
not have an opportunity to do so.

                           PART II - OTHER INFORMATION


ITEM 1            LEGAL PROCEEDINGS

                  Visx, Incorporated
                  ------------------

                  In May 1998,  Visx asserted  that the Company was  underpaying
                  royalties due under an  international  license  agreement (the
                  "License  Agreement")  and  submitted  the dispute for binding
                  arbitration,  which is likely to be  scheduled  in early 1999.
                  The  Company  has denied  Visx's  allegations  and  intends to
                  vigorously  defend its position under the terms of the License
                  Agreement.  Management believes that its obligations under the
                  License Agreement will not result in a material adverse effect
                  on the Company's financial condition or results of operations.

                  Mercacorp, Inc.
                  ---------------

                  On August 3, 1998, Mercacorp,  Inc. commenced an action in the
                  U.S.  District  Court  for the  Eastern  District  of New York
                  against the  Company,  Michael R. Farris  (the  President  and
                  Chief  Executive  Officer  of  the  Company),   Wall  &  Broad
                  Equities, Inc., a "purported investment banking establishment"
                  and  Isaac   Weinhouse,   the  principal  of  such   purported
                  investment   banking   establishment.   This  action  asserted
                  violations of Section 10(b) of the Securities and Exchange Act
                  of 1934 and common law fraud in  connection  with the  alleged
                  issuance  of  false  press  releases,  misrepresentations  and
                  omissions  by all of the  defendants  on which  the  plaintiff
                  allegedly  relied in purchasing the Company's Common Stock and
                  later holding  (rather than  selling)  such Common Stock.  The
                  plaintiff  asked  that they be  awarded  $5  million in actual
                  damages and $50 million in punitive damages.

                  On November 11, 1998, the plaintiff dismissed the action, with
                  prejudice,  and the parties agreed to a release of all claims.
                  In  connection  with the  dismissal  and release of claims the
                  Company issued the plaintiff two separate warrants to purchase
                  Common  Stock.  Under  the first  warrant,  the  plaintiff  is
                  entitled to purchase up to 750,000  shares of Common  Stock at
                  an exercise price of $4.00 per share, the closing bid price on
                  November 10, 1998, and under the second warrant, the plaintiff
                  is entitled to purchase up to 750,000  shares of Common  Stock
                  at an exercise price of $5.00 per share.  Both of the warrants
                  contain certain  prohibitions  against assignment and transfer
                  to third parties as well as other terms and conditions.  For a
                  more complete  description  of the terms and conditions of the
                  warrants,  reference is hereby made to the warrants  which are
                  attached to this Report as Exhibits  10.33 and 10.34,  and are
                  incorporated in this Item 1 by this reference.
       
                  Certain legal proceedings against the Company are described in
                  Item 3 (Legal  Proceedings) of the Company's Form 10-K for the
                  year ended December 31, 1997.

ITEM 2            CHANGES IN SECURITIES

                  a)  Not applicable.

                  b)  On July 2, 1998, the Company adopted a stockholder rights
                      agreement  and  declared  a dividend  distribution  of one
                      Preferred   Share   Purchase   Right   ("Right")  on  each
                      outstanding  share of the  Company's  Common  Stock.  Each
                      Right will entitle  stockholders to buy one one-thousandth
                                     

                                       28

                    
<PAGE> 

                      of a  share  of  a  new  series  of  junior  participating
                      preferred stock at an exercise price of $20.00. The Rights
                      will be exercisable  only if a person or group (other than
                      certain  exempt  persons)  acquires  15%  or  more  of the
                      Company's Common Stock.  Reference is made to the Form 8-K
                      filed by the Company on July 8, 1998,  for a more complete
                      description of the stockholder rights agreement.
                                    
                  c)  During the third  quarter ended  September  30, 1998,  the
                      Company  has sold or  issued  the  following  unregistered
                      securities:

                      (1)      In July  1998,  the  Company  issued  a total  of
                               102,798 shares of Common Stock to John W. Norris,
                               Bernard Spier and Michael R. Norris in connection
                               with  its   acquisition  of  the  assets  of  the
                               Northern  New Jersey Eye  Institute in July 1996.
                               For further  information,  see Note 8 of Notes to
                               Condensed Consolidated Financial Statements.

                      (2)      In September  1998,  the Company  issued  187,500
                               shares of Common  Stock to  Frederic B. Kremer as
                               partial  consideration  for the  acquisition,  as
                               amended,  of  the  LASIK  PMA  application.   For
                               further  information,  see  Note  7 of  Notes  to
                               Condensed Consolidated Financial Statements.

                      On November 11, 1998,  subsequent  to the end of the third
                      quarter, the Company granted Mercacorp, Inc. ("Mercacorp")
                      two separate warrants to purchase Common Stock.  Under the
                      first  warrant,  Mercacorp  is  entitled to purchase up to
                      750,000  shares of Common  Stock at an  exercise  price of
                      $4.00 per share,  and under the second warrant,  Mercacorp
                      is entitled  to  purchase  up to 750,000  shares of Common
                      Stock at an  exercise  price of $5.00 per  share.  Both of
                      these  warrants will terminate if the first warrant is not
                      exercised in full within fourteen days after the effective
                      date of a  registration  statement  covering the shares of
                      common stock to be issued upon  exercise of the  warrants.
                      Prior to the exercise of the second  warrant,  the Company
                      has the option, but not the obligation,  to repurchase the
                      second  warrant  by paying  $1.00 per  share.  The  second
                      warrant  will  expire if not  exercised  prior to November
                      2001.  For a more  complete  description  of the warrants,
                      reference  is hereby made to  Exhibits  10.33 and 10.34 to
                      this Report which are  incorporated in this Item 5 by this
                      reference.

                      The  issuance  and sale of all such shares was intended to
                      be  exempt  from  registration  and  prospectus   delivery
                      requirements  under the Securities Act of 1933, as amended
                      (the  "Securities  Act") by virtue of Section 4(2) thereof
                      due to,  among other  things,  (i) the  limited  number of
                      persons  to  whom  the  shares  were   issued,   (ii)  the
                      distribution  of  disclosure  documents to all  investors,
                      (iii)  the fact  that each  such  person  represented  and
                      warranted to the Company,  among other  things,  that such
                      person was  acquiring the shares for  investment  only and
                      not with a view to the resale or distribution thereof, and
                      (iv) the fact that  certificates  representing  the shares
                      were  issued  with a legend to the effect that such shares
                      had not been  registered  under the  Securities Act or any
                      state securities laws and could not be sold or transferred
                      in  the  absence  of  such  registration  or an  exemption
                      therefrom.

ITEM 3            DEFAULTS UPON SENIOR SECURITIES

                  Not applicable.

ITEM 4            SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ITEM 5            OTHER INFORMATION

                  Any  stockholder  desiring  to submit a proposal  or  director
                  nomination not for inclusion in the management proxy statement

of the various  agreements among LaserSight  Incorporated  ("LaserSight"),  you,
PhotoMed,  Inc.  ("PhotoMed")  and various other  parties,  dated as of July 15,
1997, need to be amended based on the Food and Drug Administration's (the "FDA")
recent approval of the LASIK Pre-Market Approval ("PMA") application.

         We have agreed as follows:

            1.    Within 10 business days after the date on which all parties to
                  this letter  have  signed a copy of this letter (the  "Payment
                  Date"),  LaserSight will pay you  $1,500,000.00,  50% of which
                  shall  be paid in cash in  immediately  available  funds to an
                  account or accounts  designated by you, and 50% of which shall
                  be paid (in  LaserSight's  sole  discretion) in either cash or
                  shares of  unregistered  LaserSight  common  stock,  $.001 par
                  value  per share  ("Common  Stock"),  the  number of shares of
                  which shall be  calculated  using the closing price of a share
                  of Common  Stock  for the ten (10)  trading  days  immediately
                  preceding  the Payment  Date.  Such shares shall have the same
                  registration  rights as are  contained  in Section  6.4 of the
                  Agreement  and  Plan  of  Merger,   dated  July  15,  1997(the
                  "Agreement and Plan of Merger"),  among  LaserSight,  PhotoMed
                  Acquisition, Inc. ("Photomed-A"),  you, Photomed, Linda Kremer
                  ("LK"),  Robert  Sataloff,  Trustee for Alan  Stewart  Kremer,
                  u/t/d December 27, 1991 ("ASK"), and Robert Sataloff,  Trustee
                  for Mark Adam  Kremer,  u/t/d  December  27, 1991  ("MAK,  and
                  together with you, Photomed, LK and ASK the "Kremer Parties"),
                  provided that such Common Stock shall be deemed Closing Shares
                  for purposes of Section 6.4, the Demand Registration Statement
                  shall remain  effective  for at least one (1) year,  no demand
                  for  registration  shall be  deemed to have  already  occurred
                  under Section 6.4 and  references  in Sections  6.4(a) and 6.4
                  (b) to the "first  anniversary  of the Closing  Date" shall be
                  revised to be "the second anniversary of the Closing Date."
<PAGE>

                  The payment  described in this paragraph 1 shall be in lieu of
                  the  $1,750,000.00  payment described in Section 2.2(a) of the
                  Agreement  and Plan of Merger  and  LaserSight  shall  have no
                  further  obligations  pursuant to such  Section so long as the
                  payment  described in the immediately  preceding  paragraph is
                  made on the  Payment  Date.  Subject  to the full  and  timely
                  performance of the  obligations  described in the  immediately
                  preceding paragraph the rights and obligations associated with
                  the unwind of the  transaction  described in Section 2.2(b) of
                  the  Agreement  and Plan of Merger are of no further  force or
                  effect  and to your  actual  knowledge  PhotoMed-A  holds full
                  right,  title and  interest to the PMA,  free and clear of any
                  claims by you and your affiliates. The parties also agree that
                  in  consideration  of the receipt of the payment  described in
                  this paragraph 1, to your actual  knowledge,  LaserSight shall
                  have the sole  discretion to pursue  commercialization  of the
                  Kremer Laser (as defined in the  Agreement and Plan of Merger)
                  and related PMA and  therefore  the parties  acknowledge  that
                  LaserSight has discharged its obligations under Section 6.5 of
                  the  Agreement  and Plan of Merger as it  relates  to  Section
                  2.2(a).

            2.    If a laser  manufactured by or for LaserSight  which uses part
                  or all of the know how of the Kremer  Laser is approved by the
                  FDA for general  commercial use for the treatment of hyperopia
                  (the "Hyperopia  Approval") prior to June 1, 1999, then within
                  thirty (30) days after the date of such  approval,  LaserSight
                  will pay to the Kremer Parties that number of shares of Common
                  Stock which results from dividing (A) $1,000,000.00 by (B) the
                  average  closing  price of a share of Common Stock for the ten
                  (10)  day  period  immediately   preceding  the  date  of  the
                  Hyperopia Approval (the "Hyperopia Consideration"). The number
                  of shares to be issued  pursuant to this  paragraph 2 shall be
                  limited by the terms of Section 2.3 of the  Agreement and Plan
                  of  Merger.  The last  sentence  of  Section  2.2(c) is hereby
                  deleted.  If Hyperopia Approval is granted on or after June 1,
                  1999 but prior to June 1, 2000, then the $1,000,000.00  amount
                  utilized to calculate  the  Hyperopia  Consideration  shall be
                  reduced by the number resulting from multiplying  $2,739.73 by
                  the number of days which have elapsed  since June 1, 1999.  If
                  Hyperopia  Approval  is  granted  on or after  June 1, 2000 no
                  payment shall be due pursuant to this  paragraph 2. If between
                  the date  hereof  and June 1,  2000  another  entity  which is
                  seeking   Hyperopia   Approval  (the  "Third   Party")  either
                  purchases substantially all of LaserSight's assets or acquires
                  at least eighty-five percent (85%) of LaserSight's outstanding
                  Common Stock or LaserSight purchases  substantially all of the
                  Third Party's assets or acquires at least eighty-five  percent
                  (85%) of the  Third  Party's  outstanding  common  stock,  and
                  subsequent to the closing of such transaction either ceases to
                  actively pursue or abandons Hyperopia Approval,  then upon the
                  date the relevant party ceases to actively  pursue or abandons
                  Hyperopia  Approval it shall be deemed that Hyperopia Approval
                  has been obtained.
<PAGE>

                  The payment  described in this section shall be in lieu of the
                  payment  described in Section 2.2(c) of the Agreement and Plan
                  of  Merger  and upon  making  such  payment  (or if  Hyperopia
                  Approval  is not  obtained  prior to June 1, 2000)  LaserSight
                  shall  have no further  obligation  pursuant  to such  Section
                  other  than  its  indemnification   obligations  contained  in
                  Section 8 of the Agreement and Plan of Merger.

                  You  agree,  as your time  permits,  to assist  LaserSight  in
                  obtaining the Hyperopia Approval described in this paragraph 2
                  by (i) performing clinical trials,  (ii) providing  LaserSight
                  with the  results  of such  trials in a form which may be used
                  for   preparation   for  submission  to  the  FDA,  and  (iii)
                  performing such other services as are agreed to by the parties
                  from time to time.  In  connection  with such  assistance  you
                  agree to only  utilize  the  services  of  current  LaserSight
                  employees,  which shall be provided to you promptly  upon your
                  request,   and  not  to  retain  any  third  parties   without
                  LaserSight's  prior  approval.  LaserSight  shall  comply with
                  Section 6.5 (other than 6.5(iii)) of the Agreement and Plan of
                  Merger and all  references to FDA Approval  shall be deemed to
                  refer to Hyperopia Approval, references to the PMA application
                  shall be  deemed  to refer to the  hyperopia  application  and
                  references  to PMA  shall  be  deemed  to  refer  to a PMA for
                  Hyperopia Approval. You shall not have liability of any nature
                  whatsoever  based on LaserSight's  failure to obtain Hyperopia
                  Approval.

         3.       Within two weeks  after the  Payment  Date,  LaserSight  shall
                  provide you with a scanning laser which, as further  described
                  below, you shall utilize to pursue FDA equivalency approval of
                  LaserSight's   refractive  scanning  laser  system  (which  is
                  currently in clinical  trials) as compared to the FDA approval
                  granted to the  Kremer  Laser on July 29,  1998 in  connection
                  with the PMA (the "FDA Equivalence Approval").

                  You  directly or  indirectly  agree to  utilize,  as your time
                  permits,  the scanning laser provided by LaserSight,  together
                  with  such  other  resources  which  you  deem  necessary,  to
                  generate  clinical data for  submission to the FDA in order to
                  facilitate  receipt of FDA  Equivalence  Approval.  LaserSight
                  shall be responsible  for reasonable  out-of-pocket  costs and
                  expenses   actually   incurred   in  amounts   not  to  exceed
                  $150,000.00  in  connection  with  your  pursuit  of  the  FDA
                  Equivalence Approval and any expenses in excess of such amount
                  shall  be  borne  by  you,   unless  approved  in  advance  by
                  LaserSight.  LaserSight shall reimburse you within thirty (30)
                  days  after  it  receives  proper  documentation  of  expenses
                  incurred  pursuant to the terms of the previous  sentence.  By
                  the tenth day after the end of each  month,  LaserSight  shall
                  provide to you a written  report  setting  forth in detail the
                  amount of costs and expenses incurred in the immediately prior
                  month and  cumulatively  from the date the scanning  laser has
                  been  received  by  you  in  connection  with  the  LaserSight
                  resources you have  utilized.  Within five (5) days after your

<PAGE>
                  receipt  of such  report  from  LaserSight  you  will  provide
                  LaserSight  with a  report  that  sets  forth  all  costs  and
                  expenses (on a monthly and cumulative basis) you have incurred
                  in  connection   with  the  pursuit  of  the  FDA  Equivalence
                  Approval.  LaserSight  shall have the right to terminate  your
                  involvement in this process and the above-described funding if
                  LaserSight  determines  that you have  failed to satisfy  your
                  obligations in connection  with this paragraph 3. In the event
                  of such a termination by LaserSight, LaserSight will reimburse
                  you for costs and expenses incurred  (pursuant to the terms of
                  this  paragraph)  prior to the date of such  termination.  You
                  shall not have any liability of any nature whatsoever based on
                  LaserSight's failure to obtain FDA Equivalence Approval.

                  If on or prior to the date which is four (4) months  after the
                  date on which  LaserSight  delivers to you the scanning  laser
                  described in this paragraph (the "Equivalency  Approval Date")
                  FDA grants the FDA Equivalence Approval,  then LaserSight will
                  pay the Kremer  Parties  $1,000,000.00.  If such  approval  is
                  received after the Equivalency  Approval Date but prior to the
                  first year anniversary of the Equivalency  Approval Date, then
                  LaserSight shall pay the Kremer Parties $1,000,000.00 less the
                  number resulting from  multiplying  $2,739.73 times the number
                  of days  which have  elapsed  since the  Equivalency  Approval
                  Date. If FDA  Equivalence  Approval is granted on or after the
                  first year  anniversary  of the  Equivalency  Approval Date no
                  payment shall be due pursuant to this paragraph 3. Any payment
                  required by the terms of this  paragraph  shall be made within
                  10 days after the receipt of FDA Equivalence  Approval by wire
                  transferring,  in immediately  available  funds,  the required
                  payment amount to an account or accounts  designated by you as
                  agent for the Kremer Parties.

                  The payment  described in this section shall be in lieu of the
                  payment  described in Section 2.2(d) of the Agreement and Plan
                  of Merger and upon making such payment (or if FDA  Equivalence
                  Approval is not obtained  prior to the first year  anniversary
                  of the  Equivalency  Approval Date)  LaserSight  shall have no
                  further  obligation  pursuant to such  Section  other than its
                  indemnification  obligations  contained  in  Section  8 of the
                  Agreement and Plan of Merger.

            4.    If LaserSight  acquires (through license,  with the ability to
                  sublicense,  or  otherwise)  the rights to utilize the patents
                  previously held by Pillar Point Partners,  Summit  Technology,
                  Inc. or Visx, Inc.  (collectively,  the "PP Patents") and as a
                  result of such  acquisition is not required in connection with
                  such  acquisition to pay a per procedure fee or royalty,  then
                  LaserSight agrees that it will not assert against you, Eyes of
                  the Future,  P.C.,  a  Pennsylvania  professional  corporation
                  ("EOTF"),  Frederic B.  Kremer,  M.D.,  P.C.,  a  Pennsylvania
                  professional  corporation  ("PC"),  or a Kremer  Affiliate (as
                  defined in the Patent Purchase Agreement, dated July 15, 1997,
                  between  you and  LaserSight)  for so long as you  maintain an
                 
<PAGE>

                  ownership  interest of at least 25% in EOTF and PC and satisfy
                  such definition of Kremer Affiliate, as applicable,  any claim
                  for infringement of such Pillar Point patents based on your or
                  such  entities'  use of up to three (3)  excimer  lasers.  The
                  non-assertion  clauses  of this  section do not  constitute  a
                  license or convey any right or  interest in the PP Patents and
                  is not  assignable  or otherwise  transferable  by you or such
                  entities. In addition,  LaserSight agrees that it will license
                  lasers  purchased (in excess of the three (3) lasers mentioned
                  immediately  above)  by you,  EOTF  and/or  PC (as long as you
                  maintain  an  ownership  interest  of at  least  25%  in  such
                  entities)  and/or a Kremer  Affiliate on terms and  conditions
                  then  utilized by  LaserSight  for licenses of a similar scope
                  (e.g.,  number of lasers  covered by such  license,  volume of
                  procedures  performed by the licensee,  patents covered by the
                  license,  etc.)  and that if  subsequent  to the grant of such
                  license  to you,  EOTF,  PC or a Kremer  Affiliate  LaserSight
                  grants a license of a similar  scope  (taking into account the
                  number of lasers covered by such license, volume of procedures
                  performed  by the  licensee,  patents  covered by the license,
                  etc.) except at more  favorable  per procedure or royalty rate
                  than those  previously  provided to you,  EOTF, PC or a Kremer
                  Affiliate, LaserSight shall notify the relevant party and such
                  party will be  entitled  to  receive  the more  favorable  per
                  procedure  or  royalty  rate  subject  to the same  terms  and
                  conditions  under  which such more  favorable  rates have been
                  granted.

                  Notwithstanding   the   foregoing,   if  in  connection   with
                  LaserSight  acquiring  (through  licensure or  otherwise)  the
                  right to utilize the PP Patents, LaserSight is required to pay
                  a per procedure fee or other  royalty,  then the terms of this
                  section will not preclude  LaserSight from charging you, EOTF,
                  PC or a Kremer Affiliate such fees or royalties (but no amount
                  in addition to such fees or royalties)  for up to fifteen (15)
                  lasers.  In addition,  LaserSight  agrees that it will license
                  lasers  purchased  (in  excess  of  the  fifteen  (15)  lasers
                  mentioned  immediately  above) by you, EOTF and PC (as long as
                  you  maintain  an  ownership  interest of at least 25% in such
                  entities) and a Kremer  Affiliate on terms and conditions then
                  utilized by LaserSight  for licenses of a similar scope (e.g.,
                  number of lasers covered by such license, volume of procedures
                  performed  by the  licensee,  patents  covered by the license,
                  etc.) and that if  subsequent  to the grant of such license to
                  you,  EOTF,  PC or a  Kremer  Affiliate  LaserSight  grants  a
                  license of a similar  scope (taking into account the number of
                  lasers covered by such license, volume of procedures performed
                  by the licensee,  patents covered by the license, etc.) except

power to direct and cause the direction of the  management  and policies of such
person or entity, whether through the ownership of voting securities, by

            (c)  "Effective  Date"  shall  mean the date set  forth in the first
paragraph of this Agreement.

apparatus  which is  associated  therewith  wherein the sale of such  additional
apparatus is normally anticipated with the sale of the Licensed Product.
<PAGE>

            (h) "Net Recovery" shall mean the excess of all amounts  received by
LASERSIGHT  pursuant  to an action  for  infringement  of the  Licensed  Patents

infringement of the Licensed  Patents,  plus (b) all litigation,  arbitration or
other dispute  resolution costs and expenses,  including  attorney fees,  expert

pursuing the recovery of damages for infringement of the Licensed Patents.

            (i) "Net Royalties" shall mean the excess of all royalties  received

indirect  costs and expenses  incurred by the licensor  following  the Effective
Date to obtain,  maintain  or  enforce  the  applicable  patent,  plus,  (b) all
litigation,   arbitration  or  other  dispute  resolution  costs  and  expenses,

licensing or marketing the applicable  patent.  In determining the amount of Net
Royalties under this Agreement,  LASERSIGHT shall not deduct its internal salary
and benefit  expenses  incurred  to pay its own  employees  to the extent  those
expenses  exceed 2% of the  aggregate  gross  royalties  received by  LASERSIGHT
during any applicable period.

<PAGE>

      2.05. With respect to each of Licensed Patents, TLC warrants that:

            (a) the Licensed Patent is not, nor has it ever been, subject to any
injunction, judgment, order, decree, ruling or charge; and

responsibility for intellectual  property matters, no action, suit,  proceeding,
hearing,  investigation,  charge, complaint,  claim or demand (collectively,  an
"Action")  is or ever has been pending or is  threatened  which  challenges  the
legality, validity, enforceability, or ownership of the Licensed Patent; and

            (c) to the  knowledge  of TLC and each of its  employees  and agents
with responsibility for intellectual property matters, there is no basis for any
such  Action  and TLC  has  received  no  notice  asserting  that  any  proposed
development,  manufacturing,  use,  sale,  license or  disposition  of  products
covered  by the  Licensed  Patent or any  performance  of a  Licensed  Procedure
infringes or would infringe the rights of any other party, and

            (d) to the  knowledge  of TLC and each of its  employees  and agents
with  responsibility  for intellectual  property  matters,  no person has made a
written   or  oral   assertion   that   challenges   the   legality,   validity,
enforceability,   or  ownership  of  the  Licensed  Patent  during  any  license
negotiation or otherwise.

      2.06.  TLC warrants  that it has full power,  right and authority to enter
into and carry out its obligations  under this Agreement and that this Agreement
constitutes  the valid and legally  binding  obligation of TLC,  enforceable  in

Patents or result in any material breach of or constitute a material default (or

default)  under  any  agreement  or other  instrument  related  to the  Licensed
Patents.

      2.09.  LASERSIGHT  warrants that it has full power, right and authority to
enter  into and carry out its  obligations  under this  Agreement  and that this

ARTICLE III. DISCLOSURE
             ----------

      3.01.  The parties  understand and agree that no license or other right is
granted  herein  to  either  party,  directly  or by  implication,  estoppel  or
otherwise,  with  respect  to any trade  secrets or  know-how,  and that no such
license or other right shall arise from the  consummation  of this  Agreement or
from any acts,  statements or dealings leading to such  consummation.  Except as
specifically provided herein,  neither party is required hereunder to furnish or
to disclose to the other any technical or other information.

ARTICLE IV. CONFIDENTIALITY
            ---------------  
      4.01.  LASERSIGHT  and TLC realize that some  information  received by one
party from the other  pursuant  to this  Agreement  may be  confidential.  It is
therefore agreed that any information  received by one party from the other, and
clearly designated in writing as  "CONFIDENTIAL",  shall not be disclosed by the
receiving  party to any third party and shall not be used by the receiving party
for purposes  other than those  contemplated  by this  Agreement for a period of
three (3) years  from the date this  Agreement  is  terminated  for any  reason,

            (a) such information shall become publicly known through no fault of
the receiving party, or

            (b) such information was already in the receiving party's possession
by lawful means prior to the  disclosure  of such  information  to the receiving
party, or

receiving   party  by  a  third  party  who  is  not  under  any  obligation  of
confidentiality   to  the  disclosing   party,   or  (d)  such   information  is
independently  developed by the receiving  party, or (e) the receiving party has
been advised by its counsel that disclosure is
required by applicable law.

disclosed  to the  receiving  party shall not be deemed to be  available  to the

embraced by more  general  information  available  to the public or in the prior
possession of the receiving party.

ARTICLE V. GRANT OF LICENSE TO LASERSIGHT IN THE LICENSED FIELD
           ----------------------------------------------------

      5.01. TLC grants to LASERSIGHT  and its Affiliated  Companies an exclusive
license under the Licensed Patents to:

            (a) make, have made, import, use, lease, offer to sell, sell, and/or
otherwise dispose of Licensed Products;

            (b) perform and/or have performed Licensed Procedures;

            (c)  enforce  the  Licensed  Patents  including  but not limited to,
initiating legal proceedings against unrelated third parties for infringement of
the Licensed Patents; and

unrelated third parties occurring before or after the Effective Date.
<PAGE>

      5.02. TLC further  grants to LASERSIGHT  and its Affiliated  Companies the

such sublicenses.

      5.03.  TLC grants to the users of Licensed  Products  leased,  sold and/or
otherwise  transferred  by  LASERSIGHT,   its  Affiliated  Companies  and  their

performance  of  Licensed  Procedures  which  involve  the  use of the  Licensed
Products.

ARTICLE VI.  CONSIDERATION
             -------------

      6.01.  In  consideration  for the rights  granted  under Article V of this
Agreement,  LASERSIGHT shall pay to TLC an amount equal to the product of twenty
percent (20%) times the sum of (A) the aggregate Net Royalties  received  during
the term of this  Agreement by LASERSIGHT or its  Affiliated  Companies from any
present  or future  licensee  under any of the  LASERSIGHT  Patents  (listed  in
Exhibit  A) or  the  Licensed  Patents  payable  on  sales  made  or  procedures
undertaken  during  the term of this  Agreement,  plus,  (B) the  aggregate  Net
Royalties  received  during  the term of this  Agreement  by  LASERSIGHT  or its
Affiliated  Companies  from any present or future  licensee  under United States
Patent No.  4,784,135 or United States Patent No.  4,925,523  (collectively  the
"Blum/Brarren  Patents") in excess of Two Million Five Hundred  Thousand Dollars
($2,500,000) during any year beginning on the Effective Date or each anniversary
of the Effective Date, plus, (C) the aggregate Net Royalties received during the
term of this  Agreement  by  LASERSIGHT  or its  Affiliated  Companies  from any
present or future  licensee under any patent issued  subsequent to the Effective
Date of this  Agreement  that is invented or acquired by  LASERSIGHT in order to
replace the inventions claimed in the LASERSIGHT Patents or the Licensed Patents
("Replacement  Patents")  payable on sales made or procedures  undertaken during
the Term of this  Agreement,  plus,  (D) the aggregate  Net  Royalties  received
during the Term of this Agreement by LASERSIGHT, its Affiliated Companies or any
successor to  LASERSIGHT  or its  Affiliated  Companies  pursuant to a currently
existing patent license between Summit  Technology,  Inc. and TLC, plus, (E) the
Net Recovery of damages received during the Term of this Agreement by LASERSIGHT
pursuant to any action based on infringement  (including  infringement  prior to
the Effective Date) of the Licensed  Patents  brought by LASERSIGHT  pursuant to
Section 5.01 (c) or (d).

      6.02.  LASERSIGHT  shall pay all amounts due  hereunder  in United  States
dollars.  All amounts due for an accounting  period computed in other currencies
shall be converted  into United  States  dollars at the  exchange  rate for bank
transfers  from such  currency  to United  States  dollars as quoted by the head
office of Citibank  N.A.,  New York,  at the close of banking on the last day of
such accounting period (or the business day thereafter if such last day shall be
a non-business day).

<PAGE>

      6.03.  A  semiannual  accounting  period shall end on the last day of each
June and  December  during the term of this  Agreement.  Within  sixty (60) days
after the end of each such  period,  LASERSIGHT  shall  furnish to TLC a written
report containing the information  specified in Section 6.04 below and shall pay
to TLC all unpaid amounts accrued hereunder to the end of each such period.

      6.04.  LASERSIGHT  shall keep records in  sufficient  detail to permit the
determination of amounts payable hereunder and at the request and expense of TLC
will  permit  an  independent  auditor  selected  by TLC,  or any  other  person
acceptable to both TLC and LASERSIGHT to examine, during ordinary business hours
once in each calendar year,  such records and other materials as may be required
by the  auditor  or other  person to verify or  determine  the  amounts  paid or
payable under this  Agreement.  Such auditor or other person shall be instructed
to report to TLC only the amount due and payable.  If no request for examination
of such records and materials for a particular  semiannual accounting period has
been made by TLC within two (2) years after the end of said period, the right to
examine such records and materials for said period,  and the  obligation to keep
such  records  and  materials  for said period  shall  terminate.  

ARTICLE  VII.  TREATMENT  OF LICENSE  RIGHTS UNDER  BANKRUPTCY  CODE;  BREACH OF
AGREEMENT      -----------------------------------------------------------------
- ---------

      7.01. All rights and licenses granted under this Agreement by either party
to the other including the license  itself,  are, for purposes of section 365 of
the Bankruptcy Code,  licenses to  "intellectual  property" as defined under the
Bankruptcy  Code.  The  parties  agree that both  parties  shall  retain and may
exercise  any of  their  rights  under  the  Bankruptcy  Code in the  event of a
bankruptcy filing by or against LASERSIGHT or TLC, as the case may be.

      7.02. If either party is in breach of any obligation hereunder (other than
an obligation under Article IV), the nonbreaching party shall be entitled solely
to money  damages  plus costs of  recovery  and  collection  (including  but not
limited to  attorney  fees) plus  interest  at the rate of 8% per annum from the
date such  payment was due and  payable  until  paid.  Except with  respect to a
breach under Article IV, both parties  expressly waive all rights for injunctive
and other  equitable  relief,  including but not limited to the right to bring a
claim for patent infringement.


ARTICLE VIII. PATENT MAINTENANCE
              ------------------  
      8.01.  TLC  shall be  obligated  to pay all fees and  costs  necessary  to
maintain  the  Licensed  Patents for the  respective  full term of the  Licensed
Patents; provided however,  LASERSIGHT shall monitor the payment of all fees and
costs related to the Licensed  Patents and shall  advance on TLC's  behalf,  all
such fees and costs,  which  aggregate  amount  advanced by LASERSIGHT  shall be
deducted  from the amounts due to TLC under  Article VI. If TLC is  unwilling at
any time to  reimburse  LASERSIGHT  fully  for all fees and  costs  advanced  by
LASERSIGHT necessary to maintain the Licensed Patents,  LASERSIGHT shall have an
option to pay such costs on its own behalf.  If LASERSIGHT  exercises its option
to make such payments on its own behalf,  TLC agrees to assign to LASERSIGHT all
of TLC's right, title and interest in the Licensed Patents.

      8.02. In the event any of the Licensed Patents is subject to a legal or an
administrative    proceeding   concerning   patent   validity,    patentability,
enforceability or a related issue, each party to this Agreement shall inform the
other party of such a proceeding and keep the other party regularly  apprised of
such  proceedings.  If feasible in connection  with any  proceeding,  each party
shall,  at its own  expense,  be  entitled  to submit its  comments on the other
party's submission;  provided,  however, that submission of such comments by the
party not directly involved in the proceeding shall not interfere with the party
directly participating in the proceedings.

ARTICLE IX. PATENT ENFORCEMENT
            ------------------ 
      9.01.  Enforcement.  Upon  learning  of  the  infringement  of  any of the
Licensed Patents by third parties,  each party shall inform the other in writing
of that fact, and shall supply the other with any evidence available  pertaining
to the  infringement.  Pursuant to the rights  granted  under  Section  5.01(c),
LASERSIGHT  may, at its own  discretion  and at its own expense,  take  whatever
steps are necessary to stop the  infringement  of such Licensed Patent and, with
respect to such Licensed Patent which LASERSIGHT is enforcing,  LASERSIGHT shall
have the sole right to  recover  damages  and/or  settlement  proceeds  from the
resolution   of  such   an   infringement   claim;   provided,   however,   that
notwithstanding  anything to the contrary herein that in any enforcement  action
brought by LASERSIGHT  involving its rights under this Agreement,  TLC shall, in
its sole discretion, be entitled to enter such action as a third party solely in
order to defend any counterclaim, cross claim or other claim against TLC. If TLC
elects to enter such action,  TLC shall pay all of its legal costs and expenses,
including  attorneys' fees and costs and experts' fees.  Prior to the assignment
of the Licensed Patents to LASERSIGHT pursuant to Section 8.01,  LASERSIGHT will
not compromise or settle any claim, action or proceeding  involving the Licensed
Patents,  where such action would impact the validity or  enforceability  of the
Licensed  Patents,  without the  approval of TLC,  which  approval  shall not be
unreasonably  withheld.  This Section  9.01 shall  survive  expiration  or other
termination, for any reason, of this Agreement.

      9.02. TLC as Party.  In the event of the  initiation of legal  proceedings
under  either  Sections  5.01(c),  6.01(c)  and/or  Section  9.01,  TLC or TLC's
assignee of the  applicable  Licensed  Patent,  at  LASERSIGHT's  request and at
LASERSIGHT's expense, shall agree to become a named party in such litigation if,
in  LASERSIGHT's  sole  discretion  and  opinion,   TLC's  or  TLC's  assignee's
appearance in such action is necessary  and prudent to  adjudicate  the disputed
rights in such action. In the event TLC or TLC's assignee appears in such action
pursuant to this Section 9.02, LASERSIGHT shall indemnify TLC and TLC's assignee
for  its  participation  and  shall  reimburse  TLC or  TLC's  assignee  for all
reasonable  attorney fees paid by TLC or TLC's assignee provided  however,  that
LASERSIGHT shall be entitled, at its sole cost and expense to prosecute, contest
or defend the action on behalf of TLC or TLC's  permitted  assignee with counsel
of LASERSIGHT's choosing and TLC or TLC's permitted assignee shall not admit any
liability  with respect  thereto or settle,  compromise  or discharge the action
without  the prior  written  consent  of  LASERSIGHT  so long as  LASERSIGHT  is
prosecuting,  contesting  or defending the action in good faith and TLC or TLC's
permitted  assignee  shall  cooperate  with  LASERSIGHT  in the action and shall
accept any settlement thereof  recommended by LASERSIGHT so long as TLC is fully
indemnified by LASERSIGHT.

 ARTICLE X. GOVERNING LAW; DISPUTE RESOLUTION
            ---------------------------------
 
      All parties to this Agreement,  including the undersigned  parties,  their
successors and permitted  assigns and all others who may hereafter  become bound
by this Agreement by assuming it or otherwise (all collectively,  the "Parties")
do hereby  reciprocally and irrevocably agree to the following  matters,  all of
which shall also apply fully to anyone else who has or asserts any rights  under
this  Agreement as third party  beneficiary  or otherwise  (all of whom are also
"Parties" as used herein):

            (a) Choice of Law. This Agreement shall in all respects be construed
and enforced in accordance with the law of the State of Delaware.

            (b) Claims as to Subject Matter to be Determined in Delaware Courts.
All judicial cases or proceedings involving Parties and involving subject matter
that  includes any claims,  demands or disputes  that now exist or may hereafter
arise (all collectively  called "Claims" herein) arising from or relating to any
aspect of, (1) the negotiation or execution of this Agreement,  (2) any question
as to the validity or effect of this  Agreement,  (3) anything done by anyone in
the performance of this Agreement,  (4) any alleged breach of this Agreement, or
(5) any alleged  modification,  extension or continuation of this Agreement (all
collectively  called the "Subject  Matter" herein),  shall,  whether or not such
proceedings  or cases also  involve  other  parties or  matters,  proceed and be
determined only in the state and/or federal courts located in New Castle County,
State of Delaware (all collectively, "Delaware Courts") and in the courts having
appellate jurisdiction over them, and not elsewhere.

            (c) Claims as to Subject  Matter to be Determined by Superior  Court
in Summary  Proceedings if they Qualify.  All Claims arising from or relating to
the Subject  Matter  (whether or not such Claims also involve  other  matters or
parties),  which by their nature and by the amount in  controversy  qualify as a
matter of right to be determined in the Superior  Court of the State of Delaware
in and for New Castle County (the  "Superior  Court") under its Rules  governing
Summary  Proceedings  for  Commercial  Disputes  (the  "Rules"  as  to  "Summary
Proceedings"), shall proceed and be determined in such Summary Proceedings only.
As to all such Claims which may be determined in such Summary  Proceedings  only
in  the  discretion  of the  Superior  Court,  if any  party  applies  for  such
discretionary  Summary Proceedings all Parties shall support, and no Party shall
oppose, such application.  In either case, all Parties hereby agree to submit to
the Superior Court's  jurisdiction for Summary  Proceedings,  and all Parties do
hereby submit to such  jurisdiction.  Any such Claims which cannot be determined
in such Summary  Proceedings as a matter of right, or as to which  discretionary
Summary  Proceedings  are  not  sought  or  are  denied,  shall  proceed  and be
determined in whichever Delaware Court has jurisdiction of such Claims.

            (d) No Proceedings Elsewhere.  No Party shall initiate or pursue any
case or  proceeding  of any kind against any other Party as to any Claim arising
from or relating to any aspect of the Subject Matter,  in any forum other than a
Delaware Court. No Party shall initiate or pursue any case or proceeding seeking
damages  against any Party in any forum other than the Superior Court, as to any
Claim  which,  by its nature and by the amount in  controversy,  qualifies to be
determined  as a matter of right by the Superior  Court in Summary  Proceedings,
nor as to any Claim for which discretionary Summary Proceedings are permitted by
the Superior Court's Rules,  where any Party has applied for such  discretionary
Summary  Proceedings  and the Superior  Court has granted  them,  or has not yet
refused to grant them.

            (e)  Waiver  of  Objections  to  Forum;  Waiver  of  Change of Forum
Remedies.  All Parties hereby  reciprocally and irrevocably waive in advance any
and all  objections  to the Delaware  Courts as forums based upon any of: venue,
the  doctrine of forum non  conveniens,  the  present or future  pendency of any
other case or proceeding  elsewhere,  any compulsory  counterclaim  rule, or any
other doctrine, statute, rule, practice or fact. No such case or proceeding that
is pending in a Delaware  Court shall be  dismissed,  stayed or delayed based on
any such objection to the forum,  nor transferred nor removed to any other forum
on any ground,  including  without  limitation  removal from any state  Delaware
Court to a federal court.  All Parties  reciprocally  and  irrevocably  waive in
advance  all  rights  they  might  otherwise  have to  cause  or seek  any  such
dismissal,  stay,  delay,  transfer or  removal,  and also waive all rights they
might otherwise have to assert in any forum that any Party's right to proceed in
any  Delaware  Court  under this  Agreement  is  subject to any such  objection,
dismissal, stay, delay, transfer or removal.
 
<PAGE>

          (f) Submission to In Personam Jurisdiction;  Service of Process. For
purposes of all actions or  proceedings  that  involve  Claims  arising  from or
relating to the Subject  Matter  (whether or not they also involve other matters
or parties), all Parties do hereby irrevocably submit themselves to the personal
jurisdiction of each and all of said Delaware Courts,  and do hereby irrevocably
agree for  purposes  of all such  actions or  proceedings  that  service of such
Delaware Courts' process upon them may be duly perfected by any of the following
three methods,  each of which,  in itself,  shall  constitute due and sufficient
service of such process:

              (1) Hand  delivery to a Party at its  address  stated in the first
paragraph of this Agreement.

              (2) Effective immediately Delaware Corporate Organizers, Inc., and
its successors (the "Registered  Agent") is hereby irrevocably  appointed as the
registered  agent of all  Parties  to  receive  service  of  process  under this
Agreement in Delaware.  LASERSIGHT shall promptly make appropriate  arrangements
with the Registered  Agent and shall pay its fees on a timely and regular basis,
so there  will be no break  in its  service  as such  Registered  Agent  for all
Parties. If due to non-payment or for any other reason the Registered Agent does
not serve as such,  or ceases to do so,  and no  successor  has been  appointed,
anyone desiring to serve process on a Party hereunder by serving such Registered
Agent may pay its fees,  and may take any other  reasonable  steps to obtain its
commencement or resumption of service as such Registered  Agent for the Parties,
whereupon  any  Party may then be  served  with  process  by  service  upon such
Registered  Agent, as fully as if such Registered  Agent had duly served as such
without interruption from the date of this Agreement.  Alternatively,  any Party
may  appoint  for all  Parties  a new  Registered  Agent in New  Castle  County,
Delaware,  and shall within three business days of such appointment give written
notice of such  appointment to all Parties at the addresses stated in subsection
(f)(1),  above.  Regardless  of any defect in such notice or any failure to give
it, service on such new Registered Agent shall be valid if the Party thus served
receives  actual  notice of such  service  within  three  business  days of such
service.

              (3) By any other lawful method.

ARTICLE XI.  ASSIGNMENT
             ---------- 
                  Neither this  Agreement  nor any interest  hereunder  shall be
assignable  by any party by  operation  of law or  otherwise  without  the prior
written  consent or agreement of the other party,  except  LASERSIGHT may assign
all of its interests  under this Agreement in connection with a sale or transfer
of all or  substantially  all of its business and assets to which this Agreement
relates.  This Agreement shall inure to the benefit of and shall be binding upon
the parties and their successors and permitted assigns,  and the name of a party
appearing herein shall be deemed to include the names of such party's successors
and  permitted  assigns to the extent  necessary to carry out the intent of this
Agreement.

 ARTICLE XII. INVENTION DOCUMENTATION
              -----------------------
 
      12.01.  Upon LASERSIGHT's  request at any time,  including but not limited
to, if it becomes a party to litigation in which the validity or  enforceability
of any of the Licensed  Patents is  challenged,  TLC shall provide to LASERSIGHT
all  files  and  records  related  to  the  applicable  Licensed  Patent  in its
possession,  custody or control and further agrees to fully exercise,  on behalf
of  LASERSIGHT,  (1) TLC's  rights to obtain all files and records in Jeffrey J.
Machat's  possession at such time  pertaining to the conception and reduction to
practice of the inventions claimed in the Licensed Patents, and (2) TLC's rights
to  obtain  access  to any  inventors  who are  employees  of TLC at such  time.
LASERSIGHT  shall  reimburse  TLC and  Jeffrey  J.  Machat  for  any  reasonable
out-of-pocket  expenses  associated  with the  actions  taken  pursuant  to this
section.

      12.02. TLC shall give LASERSIGHT  prompt written notice of its information
of any  intention  by  any  party  to  destroy  any  records  pertaining  to the
conception and reduction to practice of the  inventions  claimed in the Licensed
Patents,  and,  in the event TLC  chooses  not to  exercise  its  rights to take
possession  of such  records,  LASERSIGHT  shall  then  have  the  right to take
possession of such records.  In the event TLC does exercise its rights to obtain
such  records,  TLC  shall  provide  a copy of such  records  to  LASERSIGHT  at
LASERSIGHT's expense and subject to any applicable confidentiality restrictions.
<PAGE>

ARTICLE XIII. MISCELLANEOUS
              -------------

      13.01. TLC agrees that there shall be no public disclosures, including but
not  limited  to,  press  releases,  concerning  this  Agreement  or  activities
occurring  pursuant  to  this  Agreement  without   LASERSIGHT's  prior  written
approval.

      13.02. No variation or amendment of this Agreement shall bind either party
unless made in writing and agreed to in writing by duly  authorized  officers of
TLC and LASERSIGHT.

      13.03.  If any of the  provisions  of  this  Agreement  are  held  void or
unenforceable,  the remaining  provisions shall  nevertheless be effective,  the
intent being to effectuate this Agreement to the fullest extent possible.

      13.04.  If either party fails to fulfill its  obligations  (other than any
payment  obligation)  hereunder,  when such  failure is due to an act of God, or
other event such as fire,  flood,  civil  commotion,  riot,  war  (declared  and
undeclared),  revolution,  action by  government  including  delays in obtaining
governmental  approvals,  embargoes,  then said failure shall be excused for the
duration  of said  event.  This  provision  shall not apply where the failure to
fulfill an obligation  results solely from the action or inaction of a party. If
either party fails to fulfill a payment obligation hereunder,  the other party's
exclusive  remedy will be to seek monetary  damages directly caused by the delay
of payment.

      13.05. The headings in this Agreement are for convenience only and are not
intended to have any legal effect.

      13.06.  A failure by any party  hereto to  exercise  or enforce any rights
conferred  upon it by this  Agreement  shall not be deemed to be a waiver of any
such rights or operate so as to bar the exercise or  enforcement  thereof at any
subsequent time or times.

      13.07.  Nothing  in this  Agreement  is  intended  or shall be  deemed  to
constitute  a   partnership,   agency,   employer-employee   or  joint   venture
relationship  between the parties. All activities by the parties hereunder shall
be performed by them as independent contractors.  No party shall incur any debts
or make any commitments for or on behalf of the other party, unless specifically
authorized in writing by TLC or by an officer of LASERSIGHT.

      13.08. Unless otherwise terminated  hereunder,  the term of this Agreement
shall expire  simultaneously  with the last to expire of the  Licensed  Patents,
provided  however that LASERSIGHT  shall have the unilateral  right to terminate
this Agreement on thirty (30) days advance written notice.

      13.09. This Agreement constitutes the entire agreement between the parties
as to the subject matter hereof,  and all prior  negotiations,  representations,
agreements and  understandings  are merged into,  extinguished by and completely
expressed by this Agreement.

Void after 5:00 p.m., New York, New York time, on November 11, 2001

         THIS WARRANT AND THE SHARES OF COMMON STOCK  ISSUABLE  UPON EXERCISE OF
         THIS WARRANT HAVE NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933
         OR ANY STATE SECURITIES LAW AND MAY NOT BE EXERCISED, OFFERED FOR SALE,
         SOLD, PLEDGED OR OTHERWISE TRANSFERRED,  EXCEPT AS PERMITTED UNDER THIS
         WARRANT AND THEN ONLY IF REGISTERED  UNDER SUCH ACT AND ALL  APPLICABLE
         STATE  SECURITIES  LAWS OR THE  COMPANY  RECEIVES AN OPINION OF COUNSEL
         SATISFACTORY  TO THE COMPANY AND ITS COUNSEL TO THE EFFECT THAT NO SUCH
         REGISTRATION  IS  REQUIRED,  SUCH  OPINION TO BE IN THE FORM OF OPINION
         ANNEXED TO THIS WARRANT.

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

                        WARRANT TO PURCHASE COMMON STOCK
                                       of
                             LASERSIGHT INCORPORATED


         1. Grant of  Warrant.  This is to  certify  that,  for value  received,
Mercacorp,  Inc. ("Mercacorp") or its permitted assigns (individually,  "Holder"
and collectively, "Holders") are entitled, subject to the terms set forth below,
to purchase from LaserSight Incorporated, a Delaware corporation (the "Company")
or its  successors or assigns,  seven hundred fifty  thousand  (750,000),  fully
paid,  validly  issued and  non-assessable  shares of common  stock,  $0.001 par
value, of the Company  ("Common  Stock") at any time during the period beginning
on the date hereof and ending at 5:00 p.m. New York,  New York time, on November
11, 2001 (such period, the "Exercise Period") at an initial exercise price equal
to $4.00 per share. The number of shares of Common Stock to be received upon the
exercise of this Warrant and the price to be paid for each share of Common Stock
may be  adjusted  from time to time as  provided  in  Section  18. The shares of
Common Stock deliverable upon such exercise,  and as adjusted from time to time,
are hereinafter sometimes referred to as "Warrant Shares" and the exercise price
per share of Common  Stock in  effect at any time and as  adjusted  from time to
time is hereinafter sometimes referred to as the "Exercise Price."

         2. Exercise of Warrant.  This Warrant may only be exercised  during the
Exercise  Period,  in whole or in  increments  of 50,000 shares of Common Stock.
This Warrant may be exercised, subject to the provisions hereof, by presentation
and  surrender  hereof to the  Company  at its  principal  office (or such other
office or agency of the Company as it may from time to time  designate by notice
in writing  to Holder at the  address  of Holder  appearing  on the books of the
Company  ("Other  Office"))  with the Notice of  Exercise  annexed  hereto  duly
completed and executed on behalf of Holder,  with Holder's signature  guaranteed
by an eligible guarantor  institution that is a member of a recognized medallion
signature guarantee program, and accompanied by payment of the Exercise Price by
wire transfer,  certified or official bank check.  As soon as practicable  after
each such  exercise of the Warrant,  but not later than five (5)  business  days
from the date of such  exercise,  the  Company  shall issue and mail to Holder a
certificate or certificates  for the Warrant Shares issuable upon such exercise,
registered  in the name of  Holder.  This  Warrant  shall be deemed to have been
exercised  immediately  prior  to the  close  of  business  on the  date  of its
surrender for exercise as provided above, unless such date is not a day on which

<PAGE>

banks are open for  business in New York,  New York,  in which case this Warrant
shall be deemed  to have been  exercised  on the first  succeeding  day on which
banks are open for  business  in New York,  New York (such date,  the  "Exercise
Date").  The person entitled to receive the shares of Common Stock issuable upon
such exercise  shall be deemed to be the holder of record thereof from and after
the Exercise Date,  notwithstanding that certificates  representing such Warrant
Shares shall not then have been physically delivered.

         3.  Option to Compel  Exercise.  The  Company  shall  have the right to
compel the Holder to exercise  this  Warrant,  in whole,  at any time during the
fourteen (14) day period  immediately  following the date the Shelf Registration
Statement (as defined herein) is declared effective (the "Option Period"). If at
any time  during the Option  Period the  Company  provides  written  notice (the
"Company  Notice") to the Holder in accordance  with Section 25 that the Company
has elected to exercise its right to compel the  exercise of the Warrants  under
this  Section 3, the Holder  shall,  within  five (5) days of its receipt of the
Company  Notice,  present  and  surrender  this  Warrant  to the  Company at its
principal  office or Other Office,  as  applicable,  with the Notice of Exercise
annexed  hereto duly  completed and executed on behalf of Holder,  with Holder's
signature guaranteed by an eligible guarantor  institution that is a member of a
recognized  medallion signature guarantee program, and accompanied by payment of
the Exercise Price by wire transfer, certified or official bank check reasonably
acceptable  to the  Company.  If after its  receipt of the Company  Notice,  the
Holder fails to perform its obligations pursuant to this Section 3, this Warrant
shall be immediately  cancelled and the Holder will have no further rights under
this  Warrant,  and the  Company  will have no  further  obligations  under this
Warrant.

         4.  Reservation  of Shares.  The Company shall at all times reserve for
issuance  and/or delivery upon exercise of this Warrant such number of shares of
its  Common  Stock as shall  from  time to time be  required  for  issuance  and
delivery upon exercise of the Warrant in full.

         5.  Fractional  Shares.  No  fractional  shares  or scrip  representing
fractional  shares  shall be  issued  upon the  exercise  of this  Warrant.  Any
fractional share to which Holder would otherwise be entitled shall be rounded to
the nearest whole share.

         6. Warrant Register. The Company will maintain a register (the "Warrant
Register")  containing  the names and  addresses  of the Holder or Holders.  Any
Holder may change his address as shown on the Warrant Register by written notice
to the  Company  requesting  such  change.  Any notice or written  communication
required or  permitted  to be given to the Holder may be  delivered  or given by
mail to such Holder as named in the Warrant Register and at the address shown on
the Warrant  Register in  accordance  with  Section  25.  Until this  Warrant is
transferred  on the  Warrant  Register  of the  Company in  accordance  with the
provisions  hereof,  the  Company  may treat  the  Holder  named in the  Warrant
Register as the absolute owner of this Warrant for all purposes, notwithstanding
any notice to the contrary.  If this Warrant is transferred  in accordance  with
the  provisions  hereof or a Holder's  address as shown on the Warrant  Register
changes  and the  Company is  provided  notice  thereof in  accordance  with the
provision hereof, the Company shall record such transfer or change of address on
the Warrant Register as soon as practicable after receiving such notice.

         7. Warrant  Agent.  The Company may, by written  notice to all Holders,
appoint an agent  ("Warrant  Agent") who may at the option of the Company be the
Company's  transfer  agent or an  individual  employed  by the  Company  for the
purpose of maintaining the Warrant  Register,  issuing the Common Stock or other

<PAGE>

securities  then  issuable upon the exercise of this  Warrant,  exchanging  this
Warrant, or replacing this Warrant. Thereafter, any such registration, issuance,
exchange,  or replacement  shall be made at the office of the Warrant Agent. The
Warrant Agent shall be bound by all terms and  conditions  of this Warrant,  and
the Company  shall at all times  compel the Warrant  Agent to perform all of its
obligations under this Warrant.

         8.       Transfer, Exchange or Replacement.

                  (a) Transferability and Non-Negotiability of Warrant.  Neither
this Warrant nor any interest therein may be transferred or assigned in whole or
in part without compliance with all applicable federal and state securities laws
by  Holder  and the  transferee  or  assignee  thereof,  including  delivery  of
investment intent representation letters and a legal opinion in the form annexed
hereto from counsel reasonably  satisfactory to the Company,  to the effect that
such transfer or assignment is exempt from the registration  requirements of the
Securities Act of 1933 and the rules and regulations promulgated thereunder,  or
any similar  successor  statute  (collectively,  the "Securities  Act"), and any
applicable  state  securities  laws.  Subject to the preceding  sentence and the
requirements  of  Section  8(b)  below,  this  Warrant  may  be  transferred  by
endorsement  (by Holder  executing  the  Assignment  Form  annexed  hereto  with
Holder's  signature  guaranteed by an eligible  guarantor  institution that is a
member of a  recognized  medallion  signature  guarantee  program)  and delivery
thereof to the  Company or the  Warrant  Agent,  as  applicable,  together  with
payment of any applicable transfer taxes.

                  (b)  Notwithstanding  anything  set forth in this Section 8 to
the  contrary,  Holder  acknowledges  and agrees that it shall not transfer this
Warrant in whole or in Lots to (i) any individual,  firm,  corporation,  limited
liability company,  partnership,  trust or other entity, including any successor
(by merger or otherwise) of such entity (collectively, "Person"), other than the
Company,  who or which,  together with all Affiliates and Associates (as defined
in Rule 12b-2 of the Securities  Exchange Act of 1934 (the  "Exchange  Act")) of
such Person,  beneficially  owns at the time of such transfer,  or  beneficially
owned at any time  during the ninety (90) day period  immediately  prior to such
transfer,  more than one percent (1%) of the then issued and outstanding  Common
Stock,  or securities  convertible or  exercisable  into, or  exchangeable  for,
Common Stock, immediately prior to any proposed transfer of the Warrant, or (ii)
Summit   Technology,   Inc.,   Visx,   Incorporated,   Autonomous   Technologies
Corporation,  Chiron  Corporation,  or Bausch & Lomb  Incorporated  or any their
respective Affiliates or successors (by merger or otherwise).

         For  purposes  of  this  Section  8(b) a  Person  shall  be  deemed  to
"beneficially  own" any securities (i) which such Person or any of such Person's
Affiliates or Associates  beneficially owns, directly or indirectly;  (ii) which
such Person or any of such Person's  Affiliates or Associates  has (A) the right
to acquire  (whether  such right is  exercisable  immediately  or only after the
passage of time) pursuant to any agreement,  arrangement or understanding (other
than customary  agreements with and among underwriters and selling group members
with respect to a bona fide public  offering of  securities),  whether or not in
writing,  or upon the exercise of conversion  rights,  exchange rights,  rights,
warrants or options, or otherwise;  or (B) the right to vote (whether such right
is  exercisable  immediately  or only after the passage of time) pursuant to any
agreement,  arrangement or understanding; or (iii) which are beneficially owned,
directly or  indirectly,  by any other Person (or any  Affiliate or Associate of
such other Person) with which such Person or any of such Person's  Affiliates or

purpose of acquiring,  holding, voting (other than pursuant to a revocable proxy
or consent as described in the proviso to clause (ii)(B) hereof) or disposing of
any securities of the Company.

                  (c) Exchange of Warrant Upon a Transfer.  On surrender of this
Warrant for exchange,  properly  endorsed on the  Assignment  Form with Holder's
signature guaranteed by an eligible guarantor  institution that is a member of a
recognized  medallion signature guarantee program,  and subject to Section 8(a),
the  Company at its  expense  shall issue to Holder a new warrant or warrants of
like  tenor,  in the name of Holder or as Holder  (on  payment  by Holder of any
applicable  transfer  taxes) may direct,  for the number of shares issuable upon
exercise hereof.

                  (d) Replacement of Warrant.  On receipt of evidence reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this  Warrant  and,  in case of loss,  theft or  destruction,  on  delivery of a
third-party indemnity agreement reasonably satisfactory in form and substance to
the Company or, in the case of mutilation, on surrender and cancellation of this
Warrant,  the Company at its expense shall execute and deliver,  in lieu of this
Warrant, a new warrant of like tenor and amount.

         9.       Compliance with Securities Laws.

                  (a) Holder,  by acceptance of this Warrant,  acknowledges that
neither  this  Warrant nor the Warrant  Shares  have been  registered  under the
Securities  Act and  represents and warrants to the Company that this Warrant is
being  acquired for investment and not for  distribution  or resale,  solely for
Holder's own account and not as a nominee for any other person,  and that Holder
will not offer,  sell, pledge or otherwise  transfer this Warrant or any Warrant
Shares  except  as may be  permitted  under  this  Warrant  and then only (i) in
compliance with the requirements for an available  exemption from the Securities
Act and any applicable  state  securities laws, or (ii) pursuant to an effective
registration  statement  or  qualification  under  the  Securities  Act  and any
applicable state securities laws.

                  (b) Certificates for all Warrant Shares shall bear a legend in
substantially the following form:

         THESE SHARES HAVE NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933
         OR ANY STATE  SECURITIES  LAWS AND MAY NOT BE OFFERED  FOR SALE,  SOLD,
         PLEDGED OR  OTHERWISE  TRANSFERRED,  UNLESS SUCH SHARES ARE  REGISTERED
         UNDER SUCH ACT AND ALL APPLICABLE  STATE SECURITIES LAWS OR THE COMPANY
         RECEIVES  AN OPINION OF COUNSEL  SATISFACTORY  TO THE  COMPANY  AND ITS
         COUNSEL TO THE  EFFECT  THAT NO SUCH  REGISTRATION  IS  REQUIRED,  SUCH
         OPINION  TO BE IN THE  FORM  OF  OPINION  PREVIOUSLY  AGREED  TO BY THE
         COMPANY.

         10. Rights of the Holder.  Subject to Sections 18 and 19, and until the
Warrant  shall have been  exercised  as  provided  herein,  Holder  shall not be
entitled to vote, receive dividends or other  distributions on, or be deemed the
holder for any  purpose of, any Warrant  Shares or any other  securities  of the
Company  that may from time to time be issuable  upon the exercise  hereof,  nor
shall Holder, in such capacity,  enjoy any of the rights of a stockholder of the
Company  or any right to vote on, or  consent  (or  withhold  consent)  to,  the
election  of  directors  of the  Company or any other  matter  submitted  to the
stockholders of the Company, or to receive notice of meetings thereof.

         11.      Registration of Warrant Shares.

                  (a)      The Company shall:

                           (i)  prepare  and,  on or prior to  thirty  (30) days
         after the date hereof, file with the Securities and Exchange Commission
         ("SEC") a  Registration  Statement  on Form S-3 or any  successor  form
         promulgated  by the SEC in  respect  of all the  Warrant  Shares  on an
         appropriate  form for a secondary  offering to be made on a  continuous
         basis by the  Company  pursuant  to Rule 415 (the  "Shelf  Registration
         Statement"); and

                           (ii)  subject  to  Section  12  hereof,  use its best
         efforts to cause the Shelf  Registration  Statement to become effective
         as soon as practicable after such filing.

In  addition  to the  Warrant  Shares,  the  Company  may  include  in the Shelf
Registration  Statement  shares of  Common  Stock  held by any  holder of equity
securities of the Company or any securities  convertible  into or exercisable or
exchangeable  for such equity  securities,  which  holder is entitled by written
agreement  with the Company to have some or all of such  securities  included in
the Shelf Registration Statement.

                  (b) The Company  shall use its best  efforts to keep the Shelf
Registration Statement continuously effective at all times until such date as is
the earlier of: (i) the date on which all of the Warrant  Shares have been sold,
(ii) the date on which all of the Warrant Shares may be immediately  sold to the
public without registration conditions or limitations,  whether pursuant to Rule
144 or otherwise,  and (iii) the date which is the one year  anniversary  of the
date hereof;  provided that such one-year period shall be extended by the number
of days during which a Blackout  Period (as defined herein) or a Holdback Period
(as defined  herein) is in effect or invoked.  (The period of time commencing on
the date the Shelf  Registration  Statement is declared  effective and ending on
the earliest of the  foregoing  dates shall be referred to as the  "Registration
Period").  Such best  efforts  shall  include,  but not be limited to,  promptly
responding  to all  comments  received  from the  staff of the SEC.  Should  the
Company receive notification from the SEC that the Shelf Registration  Statement
will receive no action or no review from the SEC,  subject to Section 12 hereof,
the Company shall cause such Shelf  Registration  Statement to become  effective
within seven (7) business days of such SEC  notification.  Subject to Section 12
hereof,  the  Company  shall use its best  efforts to amend and  supplement  the
prospectus  contained in the Shelf Registration  Statement (the "Prospectus") in
order to permit such  Prospectus to be lawfully  delivered  until the end of the
Registration Period.

                  (c) In connection with the Shelf Registration  Statement,  the
Company shall:

                       (i) mail to each Holder a copy of the Prospectus  forming
part of the Shelf Registration Statement;

                       (ii) otherwise  comply in all material  respects with all
applicable federal securities laws, rules and regulations.
<PAGE>

                  (d)  Upon the  occurrence  of a  Blackout  Event  (as  defined
herein) or the triggering of a Holdback Period,  the Company shall notify Holder
of such  occurrence  in  accordance  with  Section 25.  Upon such  notice  being
provided  Holder  agrees not to sell any  Warrant  Shares  pursuant to the Shelf
Registration  Statement  until the Company has notified Holder that the Blackout
Period or Holdback Period, as applicable, is no longer in effect.

                  (e) Subject to Section 12 hereof,  the Company shall  promptly
supplement  and  amend the  Shelf  Registration  Statement  if  required  by the
Securities  Act or if  reasonably  requested by the Holders of a majority of the
Warrant Shares then transferable pursuant to such Shelf Registration Statement.

                  (f) Each Holder agrees to notify the Company promptly,  but in
any event within three (3)  business  days,  after the date on which all Warrant
Shares  owned by such  Holder  have been sold by such Holder so that the Company
may comply with its obligation to terminate the Shelf Registration  Statement in
accordance with Item 512 of Regulation S-K.

                  (g) The Company  hereby  represents and warrants that it meets
the  requirements  for the use of Form S-3 for  registration  of the sale by the
Holders of the Warrant Shares,  and the Company shall file all reports  required
to be filed by the  Company  with the SEC in a timely  manner so as to  maintain
such eligibility for the use of Form S-3.

         12.      Blackout Period and Holdback Events.

                  (a) During any period of up to 90 days' duration following the
occurrence of a Blackout Event (a "Blackout  Period"),  the Company shall not be
required to file, or cause to be declared  effective,  under the  Securities Act
the  Shelf  Registration  Statement,   or,  if  applicable,   the  Holders  will
discontinue  the  offer  and  sale  of  Warrant  Shares  pursuant  to the  Shelf
Registration Statement.

                  (b) The  Holders  shall  not,  if  requested  by the  managing
underwriter or underwriters of an underwritten offering and if all affiliates of
the Company (as defined in Rule 144(a)(1)  under the  Securities  Act) have been
likewise  required,  effect  any public or  private  sale of any  Common  Stock,
including a sale  pursuant to Rule 144,  during the period  ("Holdback  Period")
beginning 14 days prior to, and ending 90 days after,  the effective date of the
registration  statement  relating to a public offering of Common Stock, or other
securities  convertible  into, or exercisable or exchangeable  for, Common Stock
that is underwritten on a firm commitment basis.

                  (c) The  aggregate  number  of days  during  which one or more
Blackout  Periods or Holdback  Periods  are in effect  shall not exceed 180 days
during the  Registration  Period,  provided  that the  aggregate  number of days
during  which one or more  Blackout  Periods or  Holdback  Periods are in effect
shall not exceed 90 days in any 12 month period during the Registration Period.

                  (d) The Company shall  promptly  notify the Holders in writing
of any decision not to file the Shelf Registration Statement or not to cause the
Shelf Registration Statement to be declared effective or to discontinue sales of
Warrant  Shares  pursuant to this  Section 12,  which notice shall set forth the
reason for such decision (but not disclosing any nonpublic material information)
and shall include an undertaking  by the Company  promptly to notify the Holders
as soon as sales may resume.
<PAGE>

                  (e) For purposes of this Warrant "Blackout Event" shall mean a
determination  by the Company made in good faith,  after consulting with outside
securities counsel, that the registration of Warrant Shares under the Securities
Act or the  continuation  of the  disposition of Warrant Shares  pursuant to the
Shelf  Registration  Statement  at such time (i) would have a  material  adverse
effect upon a proposed material sale of all (or substantially all) of the assets
of the Company or a proposed material merger,  reorganization,  recapitalization
or similar current  transaction  materially  affecting the capital  structure or
equity  ownership  of the Company,  or (ii) would  require the Company to make a
public  disclosure of information,  which  disclosure has been determined by the
Company,  after consultation with outside securities  counsel,  not to be in the
best interests of the Company.

                  (f) Other holders of Common Stock,  or securities  convertible
or exercisable  into, or  exchangeable  for,  Common Stock (the "Other  Blackout
Holders") have agreed that trading pursuant to an effective Company registration
statement  may be  suspended  due to the  occurrence  of  events  the same as or
substantially  similar to the events  described  in  Section  12(e).  Therefore,
notwithstanding  anything else to the contrary  herein,  the Holders will not be
subject to a Blackout  Event  unless the  Company  notifies  all Other  Blackout
Holders that such holders must suspend trading pursuant to an effective  Company
registration statement due to such Blackout Event.

         13. Registration Procedures. In connection with the filing of the Shelf
Registration  Statement,  the Company shall effect such  registrations to permit
the sale of the Warrant Shares covered  thereby in accordance  with the intended
method or methods  of  disposition  thereof,  and in  connection  with the Shelf
Registration Statement the Company shall:

                  (a) Notify the selling Holders of Warrant Shares promptly (but
in any event within five business days), and confirm such notice in writing: (i)
when the Prospectus or any Prospectus supplement or post-effective amendment has
been  filed,  and,  with  respect  to the Shelf  Registration  Statement  or any
post-effective   amendment,  when  the  same  has  become  effective  under  the
Securities Act, (ii) of the issuance by the SEC of any stop order suspending the
effectiveness of the Shelf Registration  Statement or of any order preventing or
suspending  the  use  of  any  preliminary   prospectus  or  the  initiation  or
threatening of any  proceedings  for that purpose,  and (iii) any request by the
SEC for the amending or supplementing of such registration statement, prospectus
or prospectus supplement.

                  (b) Use its best  efforts to prevent the issuance of any order
suspending the effectiveness of the Shelf Registration Statement or of any order
preventing  or  suspending   the  use  of  the   Prospectus  or  suspending  the
qualification (or exemption from qualification) of any of the Warrant Shares for
sale in any jurisdiction and, if any such order is issued, to use its reasonable
best  efforts  to obtain  the  withdrawal  of any such  order or  suspension  of
qualification or exemption from qualification at the earliest practicable time.

                  (c) Furnish to each  selling  Holder of Warrant  Shares and to
any underwriter  participating  in such  registration at the sole expense of the
Company  at  least  one  conformed  copy  of the  Shelf  Registration  Statement
including  financial  statements and schedules  thereto and each  post-effective
amendment thereto and, if requested,  all documents incorporated or deemed to be
incorporated  therein by reference and all exhibits as soon as practicable after
such Holder or underwriter so requests.
<PAGE>

                  (d) Deliver to each  selling  Holder of Warrant  Shares and to
any underwriter  participating  in such  registration at the sole expense of the
Company as many copies of the  Prospectus  (including  each form of  preliminary
prospectus)  and  each  amendment  or  supplement   thereto  and  any  documents
incorporated by reference  therein as such Holder may reasonably  request;  and,
subject to the last  paragraph of this  Section 13, the Company  consents to the
use of such  Prospectus and each amendment or supplement  thereto by each of the
selling  Holders of Warrant Shares and the  underwriters,  if any, in connection
with the offering and sale of the Warrant Shares covered by such  Prospectus and
any amendment or supplement thereto.

                  (e)  Prior  to the  effectiveness  of the  Shelf  Registration
Statement  and  thereafter,  to use its  reasonable  best efforts to register or
qualify,  and to  cooperate  with the  selling  Holders  of  Warrant  Shares  in
connection  with the  registration  or  qualification  (or  exemption  from such
registration or  qualification)  of such Warrant Shares for offer and sale under
the securities or blue sky laws of such  jurisdictions  within the United States
as any  selling  Holder  reasonably  requests;  keep each such  registration  or
qualification  (or exemption  therefrom)  effective  during the period the Shelf
Registration Statement is required to be kept effective and do any and all other
acts or things  reasonably  necessary or advisable to enable the  disposition in
such  jurisdictions  of the  Warrant  Shares  covered by the Shelf  Registration
Statement;  provided,  however,  that the  Company  shall not be required to (i)
qualify to do  business  in any  jurisdiction  where it would not  otherwise  be
required to qualify but for this Section  13(e),  (ii) subject itself to general
taxation in any such  jurisdiction,  (iii) file a general  consent to service of
process in any such  jurisdiction,  (iv) provide any undertakings that cause the
Company  material  expense or burden,  or (v) make any change in its  charter or
by-laws,  which in each case the Company's  Board of Directors  determines to be
contrary to the best interests of the Company and its stockholders.

                  (f) Cooperate  with the selling  Holders of Warrant  Shares to
facilitate  the timely  preparation  and delivery of  certificates  representing
Warrant Shares to be sold,  which  certificates  shall not bear any  restrictive
legends  and shall be in a form in  compliance  with any  applicable  rules of a
stock exchange on which the Common Stock is then listed; and enable such Warrant
Shares to be in such  denominations  and registered in such names as Holders may
reasonably request.

                  (g)  Upon  the  occurrence  of any  event  or any  information
becoming  known to the  Company  that  makes  any  statement  made in the  Shelf
Registration  Statement or the Prospectus or any document incorporated or deemed
to be  incorporated  therein by  reference  untrue in any material  respect,  as
promptly as  practicable  prepare and file with the SEC, at the sole  expense of
the Company, a supplement or post-effective  amendment to the Shelf Registration
Statement or a supplement  to the  Prospectus  or any document  incorporated  or
deemed to be  incorporated  therein  by  reference,  or file any other  required
document so that,  as  thereafter  delivered  to the  purchasers  of the Warrant
Shares being sold  thereunder,  any such  Prospectus  will not contain an 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.

                  (h) Prepare and file with the SEC,  promptly  upon the request
of any Holder, any amendments or supplements to the Shelf Registration Statement
or  prospectus  which,  in the judgment of counsel for the Company,  is required

<PAGE>

under the  Securities  Act in connection  with the  distribution  of the Warrant
Shares by such Holders.

                  (i) Comply with all  applicable  rules and  regulations of the
SEC and make generally  available to its security  holders  earnings  statements
satisfying  the  provisions of Section 11(a) of the  Securities Act and Rule 158
thereunder (or any similar rule  promulgated  under the Securities Act) no later
than 90 days after the end of any 12-month  period (or 120 days after the end of
any 12-month period if such period is a fiscal year) commencing on the first day
of the first fiscal quarter of the Company after the effective date of the Shelf
Registration Statement, which statements shall cover said 12-month periods.

                  (j) Cooperate  with each seller of Warrant  Shares  covered by
the Shelf  Registration  Statement in connection with any filings required to be
made with the National Association of Securities Dealers, Inc.

                  (k) Use its  reasonable  best  efforts  to  cause,  at its own
expense,  all Warrant Shares relating to the Shelf Registration  Statement to be
listed on each  securities  exchange,  if any,  or  quoted on any  broker-dealer
quotation  system on which  similar  securities  issued by the  Company are then
listed.

                  (l) Furnish an opinion,  dated as of the effective date of the
Shelf Registration  Statement,  of the counsel  representing the Company for the
purpose of such registration addressed to the underwriters,  if any, making such
request,  covering such matters as are customarily  covered by such opinions and
as such underwriters may reasonably request.  Use its reasonable best efforts to
furnish  letters  dated  as of the  effective  date  of the  Shelf  Registration
Statement,   from  independent  certified  public  accountants  of  the  Company
addressed  to the  underwriters,  if any,  making such  request,  covering  such
matters as are customarily  covered by such letters and as such underwriters may
reasonably request.

         The Company may require  each seller of Warrant  Shares as to which any
registration  is being  effected  to furnish  to the  Company  such  information
regarding such seller and the distribution of such Warrant Shares as the Company
may, from time to time,  reasonably  request.  The Company may exclude from such
registration  the Warrant  Shares of any seller so long as such seller  fails to
furnish such information  within a reasonable time after receiving such request.
Each  seller as to which  the Shelf  Registration  Statement  is being  effected
agrees to  furnish  promptly  to the  Company  all  information  required  to be
disclosed in order to make the information  previously  furnished to the Company
by such seller not materially misleading.

         Each Holder of Warrant Shares  understands  that the Securities Act may
require  delivery of the Prospectus in connection with any sale thereof pursuant
to the Shelf Registration Statement,  and each such Holder shall comply with the
applicable  Prospectus delivery requirements of the Securities Act in connection
with any such sale.

         Each Holder of Warrant  Shares  agrees by  acquisition  of such Warrant
Shares that, upon actual receipt of any notice from the Company of the happening
of  any  event  of  the  kind  described  in  Section  13(a)(ii)  hereof  or any
information   becoming  known  that  makes  any  statement  made  in  the  Shelf
Registration  Statement or the Prospectus or any document incorporated or deemed
to be incorporated  therein by reference  untrue in any material  respect,  such
Holder will forthwith discontinue  disposition of such Warrant Shares covered by

<PAGE>

the Shelf  Registration  Statement or the  Prospectus  to be sold by such Holder
until  such  Holder's  receipt  of the  copies of the  supplemented  or  amended
Prospectus  contemplated  by  Section  13(d)  hereof,  or until it is advised in
writing  (the  "Advice") by the Company  that the use of the  Prospectus  may be
resumed,  and has received copies of any amendments or supplements  thereto.  In
the event the Company shall give any such notice, the Registration  Period shall
be extended by the number of days during such period from and including the date
of the  giving of such  notice  to and  including  the date when each  seller of
Warrant Shares covered by the Shelf Registration  Statement, as the case may be,
shall have  received (i) the copies of the  supplemented  or amended  Prospectus
contemplated by Section 13(d) hereof or (ii) the Advice.

         14. Expenses. With respect to such registration, the Company shall bear
all fees, costs and expenses,  including  without  limitation all  registration,
filing and NASD fees,  printing expenses,  fees and disbursements of counsel and
accountants for the Company,  all internal Company expenses,  and all legal fees
and  disbursements and other expenses of complying with state securities or blue
sky laws of any jurisdiction in which the Warrant Shares are to be registered or
qualified, but excluding any underwriting discounts and commissions and transfer
taxes and any other related selling  expenses  incurred by the selling  Holders.
The selling  Holders  will be  responsible  for fees and  disbursements  of such
parties' counsel and accountants.

         15.  Indemnification By the Company. With respect to such registration,
the Company will indemnify and hold harmless each Holder of Warrant Shares which
are included in a  registration  statement  pursuant to the  provisions  of this
Warrant,  its  directors and officers,  and any  underwriter  (as defined in the
Securities  Act) for such  Holders and each person,  if any,  who controls  such
Holder or such  underwriter  within the meaning of the Securities  Act, from and
against,   and  will  reimburse  such  Holder  and  each  such  underwriter  and
controlling person with respect to, any and all loss, claim, damage,  liability,
cost (including  without  limitation the reasonable cost of investigation of any
claim)  and  expense,  joint  or  several,  to  which  such  Holder  or any such
underwriter or controlling person may become subject under the Securities Act or
otherwise,  insofar  as such  losses,  claims,  damages,  liabilities,  costs or
expenses arise out of or are based on (i) any untrue statement or alleged untrue
statement of any material fact  contained in such  registration  statement,  any
prospectus contained therein or any amendment or supplement thereto, or (ii) the
omission or alleged  omission to state  therein a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances in which they were made, not misleading; or (iii) any violation or
alleged  violation by the Company of the Exchange Act, any state securities law,
or any rule or regulation promulgated under any of the aforementioned  statutes,
provided,  however,  that the Company will not be liable in any such case to the
extent that any such loss, claim, damage,  liability, cost or expense arises out
of or is based upon any untrue statement or alleged untrue statement or omission
or alleged  omission so made in conformity  with  information  furnished by such
Holder, such underwriter or such controlling person in writing  specifically for
use in the preparation thereof.

         16. Indemnification By Holders. With respect to such registration, each
Holder of Warrant Shares which are included in a registration statement pursuant
to the  provisions of this Warrant will,  jointly and  severally,  indemnify and
hold harmless the Company,  its directors and officers and each person,  if any,
who  controls the Company  within the meaning of the  Securities  Act,  from and
against,  and will reimburse the Company and each such controlling  person, with
respect to, any and all loss, claim, damage,  liability, cost (including without
limitation the reasonable cost of investigation of any claim) and expense, joint
or  several,  to which the  Company  or any such  controlling  person may become
subject under the Securities Act or otherwise,  insofar as such losses,  claims,

<PAGE>

damages, liabilities, costs or expenses arise out of (i) any untrue statement or
alleged  untrue  statement of any material fact  contained in such  registration
statement,  any  prospectus  contained  therein or any  amendment or  supplement
thereto  made  in  conformity   with   information   furnished  by  such  Holder
specifically for use in the preparation thereof, or (ii) the omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading made in conformity with information  furnished by
such  Holder  specifically  for use in the  preparation  thereof;  or (iii)  any
violation or alleged  violation  by the Company of the  Exchange  Act, any state
securities  law,  or  any  rule  or  regulation  promulgated  under  any  of the
aforementioned statutes,  provided that any such loss, claim, damage, liability,
cost or expense  arises out of or is based upon any untrue  statement or alleged
untrue  statement  or omission or alleged  omission so made in  conformity  with
information  furnished by such Holder  specifically  for use in the  preparation
thereof.

         17.  Rule  144.  From  the  effective  date of the  Shelf  Registration
Statement,  the Company shall use its reasonable  best efforts to timely prepare
and file all  documents  required to be filed with the SEC as shall be necessary
to enable the Holders to sell  unregistered  Warrant  Shares in accordance  with
Rule 144 under the Securities  Act. Upon the request of any Holder,  the Company
shall  deliver to such Holder a written  statement as to whether it has complied
with such requirements.

         18. Anti-Dilution  Provisions.  So long as this Warrant, or any portion
thereof,  shall remain  outstanding and unexpired,  the Exercise Price in effect
from time to time and the number  and kind of  securities  purchasable  upon the
exercise of the  Warrants  shall be subject to  adjustment  from time to time as
follows:

                  (a) If the  Company  shall (i)  declare a  dividend  or make a
distribution  on its  outstanding  shares  of  Common  Stock in shares of Common
Stock, (ii) subdivide or reclassify its outstanding  shares of Common Stock into
a greater  number of shares,  or (iii)  combine or  reclassify  its  outstanding
shares of Common Stock into a smaller number of shares (any of the foregoing,  a
"Dilutive  Event"),  the Exercise Price in effect at the time of the record date
for such  Dilutive  Event  shall be  adjusted  so that it shall  equal the price
determined by multiplying  the Exercise Price by a fraction,  the denominator of
which  shall be the  number of shares of Common  Stock  outstanding  immediately
after giving effect to such Dilutive Event,  and the numerator of which shall be
the  number  of shares of Common  Stock  outstanding  immediately  prior to such
Dilutive Event (such fraction,  the "Adjustment Factor").  Such adjustment shall
be made successively whenever any Dilutive Event shall occur.

                  (b) If the Company  shall issue rights or warrants to all, but
not less  than  all,  of the  holders  of its  Common  Stock  entitling  them to
subscribe for or purchase shares of Common Stock (or securities convertible into
Common Stock) at a price (or having a conversion  price per share) less than the
Current  Market Price (as defined  below) of the Common Stock on the record date
specified  below,  the  Exercise  Price shall be adjusted so that the same shall
equal  the  price  determined  by  multiplying  the  Exercise  Price  in  effect
immediately  prior to the date of such issuance by a fraction,  the numerator of
which shall be the sum of the number of shares of Common  Stock  outstanding  on
such record date and the number of  additional  shares of Common Stock which the
aggregate  offering  price of the total  number  of  shares  of Common  Stock so
offered (or the  aggregate  conversion  price of the  convertible  securities so
offered)  would  purchase  at the Current  Market  Price per share of the Common
Stock,  and the  denominator  of which  shall be the sum of the of the number of

<PAGE>

shares  of  Common  Stock  outstanding  on such  record  date and the  number of
additional  shares of Common Stock offered for subscription or purchase (or into
which the convertible  securities so offered are  convertible).  Such adjustment
shall be made successively whenever such rights or warrants are issued and shall
become  effective  immediately  after the record date for the  determination  of
stockholders entitled to receive such rights or warrants; and to the extent that
shares of Common Stock are not delivered (or securities  convertible into Common
Stock are not delivered)  after the  expiration of such rights or warrants,  the
Exercise  Price shall be readjusted to the Exercise Price which would then be in
effect had the  adjustments  made upon the  issuance  of such rights or warrants
been  made  upon the basis of  delivery  of only the  number of shares of Common
Stock (or securities  convertible  into Common Stock)  actually  delivered.  The
"Current  Market Price" per share of Common Stock at any date shall be deemed to
be the  average of the daily  closing  prices for the  thirty  (30)  consecutive
business days immediately before such date.

                  (c) Whenever the Exercise  Price payable upon exercise of each
Warrant is  adjusted  pursuant to Section  18(a) or 18(b),  the number of shares
purchasable  upon exercise of this Warrant shall  simultaneously  be adjusted by
dividing  the number of shares  issuable  upon  exercise of this  Warrant by the
Adjustment Factor.

                  (d) If at any time, as a result of an adjustment made pursuant
to this  Section  18(e) or 18(f),  the Holder of this Warrant  shall  thereafter
become entitled to receive any shares of the Company, other than Common Stock or
shares of any issuer other than the Company,  thereafter  the Exercise Price and
the number of such other  shares so  receivable  upon  exercise of this  Warrant
shall be  subject  to  adjustment  from time to time in a manner and on terms as
nearly  equivalent as practicable  to the provisions  with respect to the Common
Stock contained in Sections 18(a), 18(b) and 18(c).

                  (e)  If the  Company  by  reclassification  of  securities  or
otherwise,  shall change any of the securities as to which purchase rights under
this  Warrant  exist into the same or a different  number of  securities  of any
other class or classes,  this Warrant  shall  thereafter  represent the right to
acquire such number and kind of  securities  as would have been  issuable as the
result of such change with  respect to the  securities  that were subject to the
purchase rights under this Warrant immediately prior to such reclassification or
other change and the Exercise Price therefor  shall be  appropriately  adjusted,
all subject to further adjustment as provided in this Section 18.

                  (f) If at any time there shall be (i) a reorganization  (other
than a  subdivision,  combination,  reclassification,  or other change of shares
otherwise  provided for herein),  (ii) a merger or  consolidation of the Company
with or into  another  corporation  in which the  Company  is not the  surviving
entity,  or a reverse  triangular  merger in which the Company is the  surviving
entity but the shares of the  Company's  capital stock  outstanding  immediately
prior to the merger are  converted by virtue of the merger into other  property,
whether  in the  form of  securities,  cash,  or  otherwise,  or (iii) a sale or
transfer of the  Company's  properties  and assets as, or  substantially  as, an
entirety to any other person,  then, as a part of such  reorganization,  merger,
consolidation,  sale or  transfer,  lawful  provision  shall be made so that the
holder of this Warrant shall  thereafter be entitled to receive upon exercise of
this  Warrant,  during  the  period  specified  herein  and upon  payment of the
Exercise Price then in effect, the number of shares of stock or other securities
or property of the successor  corporation  resulting  from such  reorganization,
merger, consolidation,  sale or transfer that a Holder of the shares deliverable
upon  exercise  of this  Warrant  would  have been  entitled  to receive in such
reorganization, consolidation, merger, sale or transfer if this Warrant had been

<PAGE>

exercised immediately before such reorganization, merger, consolidation, sale or
transfer,  all subject to further adjustment as provided in this Section 18. The
foregoing  provisions of this Section 18(f) shall  similarly apply to successive
reorganizations,  consolidations,  mergers, sales and transfers and to the stock
or securities of any other  corporate that are at the time  receivable  upon the
exercise of this Warrant. In all events,  appropriate  adjustment (as determined
by the Company's  Board of Directors)  shall be made in the  application  of the
provisions  of this  Warrant  with  respect to the rights and  interests  of the
Holder after the  transaction,  to the end that the  provisions  of this Warrant
shall be applicable  after the event,  as near as reasonably may be, in relation
to any shares or other  property  deliverable  after that event upon exercise of
this Warrant.

                  (g) Whenever the Exercise  Price shall be adjusted as required
by the  provisions of Section 18, the Company shall promptly file in the custody
of its  Secretary or an Assistant  Secretary  at its  principal  office or Other
Office and with the Warrant Agent, if any, an officer's  certificate showing the
adjusted  Exercise  Price  determined  as  herein  provided,  setting  forth  in
reasonable detail the facts requiring such adjustment,  including a statement of
the number of  additional  shares of Common Stock or other  securities,  if any,
issuable  upon  exercise  of this  Warrant  and  such  other  facts  as shall be
necessary  to show the reason for and the manner of computing  such  adjustment.
Each  such  certificate  shall be made  available  at all  reasonable  times for
inspection by Holder and the Company shall  forthwith after each such adjustment
mail a copy of such  certificate  to Holder at its address last appearing in the
Warrant Register.

         19. Notices to Warrant Holders.  If at any time while this Warrant,  or
any portion thereof,  remains  outstanding and unexpired,  (i) the Company shall
pay any  dividend or make any  distribution  upon the Common  Stock  (other than
regular quarterly cash dividends or dividends paid in the form of Common Stock),
(ii) the  Company  shall  offer to the  holders of Common  Stock  generally  for
subscription  or  purchase  by them any share of the Company of any class or any
other rights issued by the Company,  or (iii) the capital  reorganization of the
Company,  reclassification of the capital stock of the Company, consolidation or
merger  of  the  Company  with  or  into  another  corporation,  sale  of all or
substantially  all  of  the  property  and  assets  of the  Company  to  another
corporation or voluntary or involuntary  dissolution,  liquidation or winding up
of the Company shall be effected, then in any such case, the Company shall cause
to be mailed to Holder at its  address  specified  in the Warrant  Register,  at
least 10 days prior to the date specified in (x) or (y) below, as applicable,  a
notice  containing a brief  description of the proposed event  described in (i),
(ii) or (iii)  above and  stating  the date on which (x) a record is to be taken
for  the  purpose  of  such  dividend,  distribution  or  rights,  or  (y)  such
reclassification,  reorganization,  consolidation,  merger,  sale,  dissolution,
liquidation or winding up is to take place and the date, if any, is be fixed, as
of which the holders of the Common Stock or other  securities shall receive cash
or other property  deliverable upon such event.  Notwithstanding  the above, the
failure to give such notice shall not affect the validity of any transaction for
which the notice was required to be given.

         20.  Governing  Law. This Warrant shall be governed by and construed in
accordance  with the internal  laws of the State of New York  without  regard to
such state's conflict of law provisions.

         21.  Severability.  In the event that any one or more of the provisions
contained  herein,  or the  application  thereof  in any  circumstance,  is held
invalid, illegal or unenforceable,  the validity, legality and enforceability of
any such  provision  in every  other  respect  and of the  remaining  provisions
contained herein shall not be affected or impaired thereby.

         other Holder in the aggregate owning, directly or indirectly, more than
         1,650,000 shares of Common Stock;

                  (b) make, or in way  participate  in,  directly or indirectly,

         acquisition or disposition of significant  assets of the Company or any
         other  entity)  with  the  Company  or  any  affiliate  thereof  or any

         any  recommendation or proposal to any person or other entity to engage

         Company;

                  (j)  except to the  extent  required  by law,  make any public

         For  purposes of this Section 22, the term  "voting  securities"  shall
mean (i) any  securities  which are entitled to vote upon any  matters,  whether
such  securities are entitled to vote on such matters in all events or only upon
the  occurrence  of a  default  or other  contingencies,  or (ii)  any  options,
warrants,  rights or securities  which by their terms may be convertible into or
exchangeable  for any  security  described in clause (i) of this  sentence.  The

applicable,  such  other  Holder's  exercise  of the last of the Lots and  shall
continue until the expiration of the Standstill Period.

to the other that (i) each such party is duly organized, validly existing and in
good standing under the laws of their respective  jurisdiction of incorporation,

together shall constitute one and the same instrument.

telecopy,  and shall be deemed to be  delivered  at the time and date of receipt

                              FORM OF LEGAL OPINION

                               _____________, 1998


LaserSight Incorporated
3300 University Blvd.
Suite 140
Orlando, Florida  32792

         Re:      Warrant Transfer

Gentlemen:

         We have acted as  counsel  to  [Mercacorp,  Inc.  or other  holder] , a
corporation   organized   under  the  laws  of   ________________________   (the
"Company"),  in connection with the transfer of the Warrant,  dated November 11,
1998, to purchase 750,000 shares of common stock, $.001 par value, of LaserSight
Incorporated (the "Warrant") to _________________________ ("Transferee").

         In connection with this opinion,  we have examined originals or copies,
certified or otherwise  identified to our satisfaction,  of the Warrant and such
agreements, instruments, certificates,  representations,  documents and records,
and  have  made  such  other  investigations,  as we have  deemed  necessary  or
appropriate  as a basis  for the  opinions  set  forth  herein.  As to any facts
material to the opinions  expressed  herein, we have relied upon oral or written
statements  and  representations  of officers and other  representatives  of the
Company and Transferee.

         The Transferee has represented that it is acquiring the Warrant (i) for
investment and not for distribution or resale,  and (ii) solely for Transferee's
own account and not as a nominee for any other person.

         Based upon and subject to the foregoing, we are of the opinion that the
transfer  of the  Warrant  from the  Company to  Transferee  is exempt  from the
registration requirements of the Securities Act of 1933 (the "Act").

         We express no  opinion as to the laws of any  jurisdictions  other than
the  Federal  securities  laws of the United  States of America in effect on the
date hereof,  and we assume no obligation  to revise or supplement  this opinion
should such laws be changed by legislative or  administrative  action,  judicial
decision or otherwise.

         This  opinion is solely for the benefit of you and your counsel and can
not be relied upon by any other person, corporation or entity.

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

                        WARRANT TO PURCHASE COMMON STOCK
                                       of
                             LASERSIGHT INCORPORATED


         1. Grant of  Warrant.  This is to  certify  that,  for value  received,
Mercacorp,  Inc. ("Mercacorp") or its permitted assigns (individually,  "Holder"
and collectively, "Holders") are entitled, subject to the terms set forth below,
to purchase from LaserSight Incorporated, a Delaware corporation (the "Company")
or its  successors or assigns,  seven hundred fifty  thousand  (750,000),  fully
paid,  validly  issued and  non-assessable  shares of common  stock,  $0.001 par
value, of the Company  ("Common  Stock") at any time during the period beginning
on the date hereof and ending at 5:00 p.m. New York,  New York time, on November
11, 2001 (such period, the "Exercise Period") at an initial exercise price equal
to $5.00 per share. The number of shares of Common Stock to be received upon the
exercise of this Warrant and the price to be paid for each share of Common Stock
may be  adjusted  from time to time as  provided  in  Section  19. The shares of
Common Stock deliverable upon such exercise,  and as adjusted from time to time,
are hereinafter sometimes referred to as "Warrant Shares" and the exercise price
per share of Common  Stock in  effect at any time and as  adjusted  from time to
time is hereinafter sometimes referred to as the "Exercise Price."

         2. Exercise of Warrant.  This Warrant may only be exercised  during the
Exercise  Period,  in whole or in  increments  of 50,000  shares of Common Stock
(each such increment  hereinafter  referred to as a "Lot").  This Warrant may be
exercised,  subject to the  provisions  hereof,  by  presentation  and surrender
hereof to the Company at its principal office (or such other office or agency of
the Company as it may from time to time designate by notice in writing to Holder
at the address of Holder appearing on the books of the Company ("Other Office"))
with the Notice of Exercise annexed hereto duly completed and executed on behalf
of  Holder,  with  Holder's  signature   guaranteed  by  an  eligible  guarantor
institution  that is a member  of a  recognized  medallion  signature  guarantee
program,  and  accompanied  by payment of the Exercise  Price by wire  transfer,
certified  or  official  bank  check.  As soon as  practicable  after  each such
exercise of the Warrant, but not later than five (5) business days from the date
of such  exercise,  the Company shall issue and mail to Holder a certificate  or
certificates  for the Warrant Shares issuable upon such exercise,  registered in

<PAGE>

the  name of  Holder.  This  Warrant  shall be  deemed  to have  been  exercised
immediately  prior to the close of  business  on the date of its  surrender  for
exercise  as  provided  above,  unless such date is not a day on which banks are
open for business in New York,  New York,  in which case this  Warrant  shall be
deemed to have been  exercised  on the first  succeeding  day on which banks are
open for business in New York,  New York (such date, the "Exercise  Date").  The
person  entitled  to  receive  the  shares of Common  Stock  issuable  upon such
exercise  shall be deemed to be the holder of record  thereof from and after the
Exercise  Date,  notwithstanding  that  certificates  representing  such Warrant
Shares shall not then have been physically delivered.

         3. Forfeiture of Warrant. By its acceptance of this Warrant, the Holder
acknowledges  and agrees that in the event that that certain warrant to purchase
seven hundred fifty thousand shares  (750,000) of the Company's  Common Stock at
an Exercise Price of $4.00 per share,  originally  issued to Mercacorp and dated
as of the date hereof, is cancelled in accordance with the terms of Section 3 of
such warrant,  this Warrant shall be  immediately  cancelled and the Holder will
have no further rights under this Warrant,  and the Company will have no further
obligations under this Warrant.

         4.       Option to Repurchase.

                  (a) At  anytime  after the date  hereof,  at the option of the
  Company,  the Company may  repurchase  all or any portion of this Warrant at a
  price of $1.00 per share,  provided that (i) any such repurchase shall be made
  in equal Lots,  (ii) the option  granted  under this Section 4(a) shall not be
  exercised  with  respect to any  portion of this  Warrant  that the Holder has
  elected to exercise, and (iii) the Holder shall have the right to exercise all
  or any  portion of this  Warrant  during  the ten (10) day period  immediately
  following the date the Company provides notice that it has elected to exercise
  it option pursuant to this Section 4(a).

                  (b) At least five (5) business days prior to the repurchase of
  any unexercised  portion of this Warrant pursuant to Section 4(a), the Company
  shall send written notice to the Holder notifying the Holder of the repurchase
  to be effected,  specifying the number of Lots being repurchased, the date and
  time of such  repurchase,  the place at which  payment  may be  obtained,  and
  calling upon the Holder to  surrender to the Company,  in the manner and place
  designated, such unexercised portion of this Warrants being repurchased. On or
  after the date  designated for  repurchase,  the Holder shall surrender to the
  Company  certificates or other documents  representing  such warrants,  in the
  manner and at the place designated in the repurchase notice, and thereupon (i)
  the  repurchase  price with  respect to that  portion  of this  Warrant  being
  repurchased shall be paid to the Holder, and (ii) that portion of this Warrant
  which is repurchased shall be cancelled.

         5.  Reservation  of Shares.  The Company shall at all times reserve for
issuance  and/or delivery upon exercise of this Warrant such number of shares of
its  Common  Stock as shall  from  time to time be  required  for  issuance  and
delivery upon exercise of the Warrant in full.

         6.  Fractional  Shares.  No  fractional  shares  or scrip  representing
fractional  shares  shall be  issued  upon the  exercise  of this  Warrant.  Any
fractional share to which Holder would otherwise be entitled shall be rounded to
the nearest whole share.

         7. Warrant Register. The Company will maintain a register (the "Warrant
Register")  containing  the names and  addresses  of the Holder or Holders.  Any
Holder may change his address as shown on the Warrant Register by written notice
to the  Company  requesting  such  change.  Any notice or written  communication

<PAGE>

required or  permitted  to be given to the Holder may be  delivered  or given by
mail to such Holder as named in the Warrant Register and at the address shown on
the Warrant  Register in  accordance  with  Section  26.  Until this  Warrant is
transferred  on the  Warrant  Register  of the  Company in  accordance  with the
provisions  hereof,  the  Company  may treat  the  Holder  named in the  Warrant
Register as the absolute owner of this Warrant for all purposes, notwithstanding
any notice to the contrary.  If this Warrant is transferred  in accordance  with
the  provisions  hereof or a Holder's  address as shown on the Warrant  Register
changes  and the  Company is  provided  notice  thereof in  accordance  with the
provision hereof, the Company shall record such transfer or change of address on
the Warrant Register as soon as practicable after receiving such notice.

         8. Warrant  Agent.  The Company may, by written  notice to all Holders,
appoint an agent  ("Warrant  Agent") who may at the option of the Company be the
Company's  transfer  agent or an  individual  employed  by the  Company  for the
purpose of maintaining the Warrant  Register,  issuing the Common Stock or other
securities  then  issuable upon the exercise of this  Warrant,  exchanging  this
Warrant, or replacing this Warrant. Thereafter, any such registration, issuance,
exchange,  or replacement  shall be made at the office of the Warrant Agent. The
Warrant Agent shall be bound by all terms and  conditions  of this Warrant,  and
the Company  shall at all times  compel the Warrant  Agent to perform all of its
obligations under this Warrant.

         9.       Transfer, Exchange or Replacement.

                  (a) Transferability and Non-Negotiability of Warrant.  Neither
this Warrant nor any interest therein may be transferred or assigned in whole or
in part without compliance with all applicable federal and state securities laws
by  Holder  and the  transferee  or  assignee  thereof,  including  delivery  of
investment intent  representation letter and a legal opinion in the form annexed
hereto from counsel reasonably  satisfactory to the Company,  to the effect that
such transfer or assignment is exempt from the registration  requirements of the
Securities Act of 1933 and the rules and regulations promulgated thereunder,  or
any similar  successor  statute  (collectively,  the "Securities  Act"), and any
applicable  state  securities  laws.  Subject to the preceding  sentence and the
requirements  of  Section  9(b)  below,  this  Warrant  may  be  transferred  by
endorsement  (by Holder  executing  the  Assignment  Form  annexed  hereto  with
Holder's  signature  guaranteed by an eligible  guarantor  institution that is a
member of a  recognized  medallion  signature  guarantee  program)  and delivery
thereof to the  Company or the  Warrant  Agent,  as  applicable,  together  with
payment of any applicable transfer taxes.

                  (b)  Notwithstanding  anything  set forth in this Section 9 to
the  contrary,  Holder  acknowledges  and agrees that it shall not transfer this
Warrant in whole or in Lots to (i) any individual,  firm,  corporation,  limited
liability company,  partnership,  trust or other entity, including any successor
(by merger or otherwise) of such entity (collectively, "Person"), other than the
Company,  who or which,  together with all Affiliates and Associates (as defined
in Rule 12b-2 of the Securities  Exchange Act of 1934 (the  "Exchange  Act")) of
such Person,  beneficially  owns at the time of such transfer,  or  beneficially
owned at any time  during the ninety (90) day period  immediately  prior to such
transfer,  more than one percent (1%) of the then issued and outstanding  Common
Stock,  or securities  convertible or  exercisable  into, or  exchangeable  for,
Common Stock, immediately prior to any proposed transfer of the Warrant, or (ii)
Summit   Technology,   Inc.,   Visx,   Incorporated,   Autonomous   Technologies
Corporation,  Chiron  Corporation,  or Bausch & Lomb  Incorporated  or any their
respective Affiliates or successors (by merger or otherwise).
<PAGE>

         For  purposes  of  this  Section  9(b) a  Person  shall  be  deemed  to
"beneficially  own" any securities (i) which such Person or any of such Person's
Affiliates or Associates  beneficially owns, directly or indirectly;  (ii) which
such Person or any of such Person's  Affiliates or Associates  has (A) the right
to acquire  (whether  such right is  exercisable  immediately  or only after the
passage of time) pursuant to any agreement,  arrangement or understanding (other
than customary  agreements with and among underwriters and selling group members
with respect to a bona fide public  offering of  securities),  whether or not in
writing,  or upon the exercise of conversion  rights,  exchange rights,  rights,
warrants or options, or otherwise;  or (B) the right to vote (whether such right
is  exercisable  immediately  or only after the passage of time) pursuant to any
agreement,  arrangement or understanding; or (iii) which are beneficially owned,
directly or  indirectly,  by any other Person (or any  Affiliate or Associate of
such other Person) with which such Person or any of such Person's  Affiliates or
Associates has any agreement, arrangement or understanding (other than customary
agreements with and among underwriters and selling group members with respect to
a bona fide public offering of securities),  whether or not in writing,  for the
purpose of acquiring,  holding, voting (other than pursuant to a revocable proxy
or consent as described in the proviso to clause (ii)(B) hereof) or disposing of
any securities of the Company.

                  (c) Exchange of Warrant Upon a Transfer.  On surrender of this
Warrant for exchange,  properly  endorsed on the  Assignment  Form with Holder's
signature guaranteed by an eligible guarantor  institution that is a member of a
recognized  medallion signature guarantee program,  and subject to Section 9(a),
the  Company at its  expense  shall issue to Holder a new warrant or warrants of
like  tenor,  in the name of Holder or as Holder  (on  payment  by Holder of any
applicable  transfer  taxes) may direct,  for the number of shares issuable upon
exercise hereof.

                  (d) Replacement of Warrant.  On receipt of evidence reasonably
satisfactory  to the Company of the loss,  theft,  destruction  or mutilation of
this  Warrant  and,  in case of loss,  theft or  destruction,  on  delivery of a
third-party indemnity agreement reasonably satisfactory in form and substance to
the Company or, in the case of mutilation, on surrender and cancellation of this
Warrant,  the Company at its expense shall execute and deliver,  in lieu of this
Warrant, a new warrant of like tenor and amount.

         10.      Compliance with Securities Laws.

                  (a) Holder,  by acceptance of this Warrant,  acknowledges that
neither  this  Warrant nor the Warrant  Shares  have been  registered  under the
Securities  Act and  represents and warrants to the Company that this Warrant is
being  acquired for investment and not for  distribution  or resale,  solely for
Holder's own account and not as a nominee for any other person,  and that Holder
will not offer,  sell, pledge or otherwise  transfer this Warrant or any Warrant
Shares  except  as may be  permitted  under  this  Warrant  and then only (i) in
compliance with the requirements for an available  exemption from the Securities
Act and any applicable  state  securities laws, or (ii) pursuant to an effective
registration  statement  or  qualification  under  the  Securities  Act  and any
applicable state securities laws.

                   (b)  Certificates  for all Warrant Shares shall bear a legend
in substantially the following form:

         THESE SHARES HAVE NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933
         OR ANY STATE  SECURITIES  LAWS AND MAY NOT BE OFFERED  FOR SALE,  SOLD,
         PLEDGED OR  OTHERWISE  TRANSFERRED  UNLESS SUCH  SHARES ARE  REGISTERED

<PAGE>

         UNDER SUCH ACT AND ALL APPLICABLE  STATE SECURITIES LAWS OR THE COMPANY
         RECEIVES  AN OPINION OF COUNSEL  SATISFACTORY  TO THE  COMPANY  AND ITS
         COUNSEL TO THE  EFFECT  THAT NO SUCH  REGISTRATION  IS  REQUIRED,  SUCH
         OPINION  TO BE IN THE  FORM  OF  OPINION  PREVIOUSLY  AGREED  TO BY THE
         COMPANY.
 .

         11. Rights of the Holder.  Subject to Sections 19 and 20, and until the
Warrant  shall have been  exercised  as  provided  herein,  Holder  shall not be
entitled to vote, receive dividends or other  distributions on, or be deemed the
holder for any  purpose of, any Warrant  Shares or any other  securities  of the
Company  that may from time to time be issuable  upon the exercise  hereof,  nor
shall Holder, in such capacity,  enjoy any of the rights of a stockholder of the
Company  or any right to vote on, or  consent  (or  withhold  consent)  to,  the
election  of  directors  of the  Company or any other  matter  submitted  to the
stockholders of the Company, or to receive notice of meetings thereof.

         12.      Registration of Warrant Shares.

                  (a)      The Company shall:

                           (i)  prepare  and,  on or prior to  thirty  (30) days
         after the date hereof, file with the Securities and Exchange Commission
         ("SEC") a  Registration  Statement  on Form S-3 or any  successor  form
         promulgated  by the SEC in  respect  of all the  Warrant  Shares  on an
         appropriate  form for a secondary  offering to be made on a  continuous
         basis by the  Company  pursuant  to Rule 415 (the  "Shelf  Registration
         Statement"); and

                           (ii)  subject  to  Section  13  hereof,  use its best
         efforts to cause the Shelf  Registration  Statement to become effective
         as soon as practicable after such filing.

In  addition  to the  Warrant  Shares,  the  Company  may  include  in the Shelf
Registration  Statement  shares of  Common  Stock  held by any  holder of equity
securities of the Company or any securities  convertible  into or exercisable or
exchangeable  for such equity  securities,  which  holder is entitled by written
agreement  with the Company to have some or all of such  securities  included in
the Shelf Registration Statement.

                  (b) The Company  shall use its best  efforts to keep the Shelf
Registration Statement continuously effective at all times until such date as is
the earlier of: (i) the date on which all of the Warrant  Shares have been sold,
(ii) the date on which all of the Warrant Shares may be immediately  sold to the
public without registration conditions or limitations,  whether pursuant to Rule
144 or otherwise,  and (iii) the date which is the one year  anniversary  of the
date hereof;  provided that such one-year period shall be extended by the number
of days during which a Blackout  Period (as defined herein) or a Holdback Period
(as defined  herein) is in effect or is invoked.  (The period of time commencing
on the date the Shelf Registration Statement is declared effective and ending on
the earliest of the  foregoing  dates shall be referred to as the  "Registration
Period").  Such best  efforts  shall  include,  but not be limited to,  promptly
responding  to all  comments  received  from the  staff of the SEC.  Should  the
Company receive notification from the SEC that the Shelf Registration  Statement
will receive no action or no review from the SEC,  subject to Section 13 hereof,

<PAGE>

the Company shall cause such Shelf  Registration  Statement to become  effective
within seven (7) business days of such SEC  notification.  Subject to Section 13
hereof,  the  Company  shall use its best  efforts to amend and  supplement  the
prospectus  contained in the Shelf Registration  Statement (the "Prospectus") in
order to permit such  Prospectus to be lawfully  delivered  until the end of the
Registration Period.

                  (c) In connection with the Shelf Registration  Statement,  the
Company shall:

                            (i)  mail to each  Holder  a copy of the  Prospectus
forming part of the Shelf Registration Statement;

                            (ii) otherwise comply in all material  respects with
all applicable federal securities laws, rules and regulations.

                  (d)  Upon the  occurrence  of a  Blackout  Event  (as  defined
herein) or the triggering of a Holdback Period,  the Company shall notify Holder
of such  occurrence  in  accordance  with  Section 26.  Upon such  notice  being
provided  Holder  agrees not to sell any  Warrant  Shares  pursuant to the Shelf
Registration  Statement  until the Company has notified Holder that the Blackout
Period or Holdback Period, as applicable, is no longer in effect.

                  (e) Subject to Section 13 hereof,  the Company shall  promptly
supplement  and  amend the  Shelf  Registration  Statement  if  required  by the
Securities  Act or if  reasonably  requested by the Holders of a majority of the
Warrant Shares then transferable pursuant to such Shelf Registration Statement.

                  (f) Each Holder agrees to notify the Company promptly,  but in
any event within three (3)  business  days,  after the date on which all Warrant
Shares  owned by such  Holder  have been sold by such Holder so that the Company
may comply with its obligation to terminate the Shelf Registration  Statement in
accordance with Item 512 of Regulation S-K.

                  (g) The Company  hereby  represents and warrants that it meets
the  requirements  for the use of Form S-3 for  registration  of the sale by the
Holders of the Warrant Shares,  and the Company shall file all reports  required
to be filed by the  Company  with the SEC in a timely  manner so as to  maintain
such eligibility for the use of Form S-3.

         13.      Blackout Period and Holdback Events.

                  (a) During any period of up to 90 days' duration following the
occurrence of a Blackout Event (a "Blackout  Period"),  the Company shall not be
required to file, or cause to be declared  effective,  under the  Securities Act
the  Shelf  Registration  Statement,   or,  if  applicable,   the  Holders  will
discontinue  the  offer  and  sale  of  Warrant  Shares  pursuant  to the  Shelf
Registration Statement.

                  (b) The  Holders  shall  not,  if  requested  by the  managing
underwriter or underwriters of an underwritten offering and if all affiliates of
the Company (as defined in Rule 144(a)(1)  under the  Securities  Act) have been
likewise  required,  effect  any public or  private  sale of any  Common  Stock,
including a sale  pursuant to Rule 144,  during the period  ("Holdback  Period")
beginning 14 days prior to, and ending 90 days after,  the effective date of the
registration  statement  relating to a public offering of Common Stock, or other
securities  convertible  into, or exercisable or exchangeable  for, Common Stock
that is underwritten on a firm commitment basis.
<PAGE>

                  (c) The  aggregate  number  of days  during  which one or more
Blackout  Periods or Holdback  Periods  are in effect  shall not exceed 180 days
during the  Registration  Period,  provided  that the  aggregate  number of days
during  which one or more  Blackout  Periods or  Holdback  Periods are in effect
shall not exceed 90 days in any 12 month period during the Registration Period.

                  (d) The Company shall  promptly  notify the Holders in writing
of any decision not to file the Shelf Registration Statement or not to cause the
Shelf Registration Statement to be declared effective or to discontinue sales of
Warrant  Shares  pursuant to this  Section 13,  which notice shall set forth the
reason for such decision (but not disclosing any nonpublic material information)
and shall include an undertaking  by the Company  promptly to notify the Holders
as soon as sales may resume.

                  (e) For purposes of this Warrant "Blackout Event" shall mean a
determination  by the Company made in good faith,  after consulting with outside
securities counsel, that the registration of Warrant Shares under the Securities
Act or the  continuation  of the  disposition of Warrant Shares  pursuant to the
Shelf  Registration  Statement  at such time (i) would have a  material  adverse
effect upon a proposed material sale of all (or substantially all) of the assets
of the Company or a proposed material merger,  reorganization,  recapitalization
or similar current  transaction  materially  affecting the capital  structure or
equity  ownership  of the Company,  or (ii) would  require the Company to make a
public  disclosure of information,  which  disclosure has been determined by the
Company,  after consultation with outside securities  counsel,  not to be in the
best interests of the Company.

                  (f) Other holders of Common Stock,  or securities  convertible
or exercisable  into, or  exchangeable  for,  Common Stock (the "Other  Blackout
Holders") have agreed that trading pursuant to an effective Company registration
statement  may be  suspended  due to the  occurrence  of  events  the same as or
substantially  similar to the events  described  in  Section  13(e).  Therefore,
notwithstanding  anything else to the contrary  herein,  the Holders will not be
subject to a Blackout  Event  unless the  Company  notifies  all Other  Blackout
Holders that such holders must suspend trading pursuant to an effective  Company
registration statement due to such Blackout Event.

         14. Registration Procedures. In connection with the filing of the Shelf
Registration  Statement,  the Company shall effect such  registrations to permit
the sale of the Warrant Shares covered  thereby in accordance  with the intended
method or methods  of  disposition  thereof,  and in  connection  with the Shelf
Registration Statement the Company shall:

                  (a) Notify the selling Holders of Warrant Shares promptly (but
in any event within five business days), and confirm such notice in writing: (i)
when the Prospectus or any Prospectus supplement or post-effective amendment has
been  filed,  and,  with  respect  to the Shelf  Registration  Statement  or any
post-effective   amendment,  when  the  same  has  become  effective  under  the
Securities Act, (ii) of the issuance by the SEC of any stop order suspending the
effectiveness of the Shelf Registration  Statement or of any order preventing or
suspending  the  use  of  any  preliminary   prospectus  or  the  initiation  or
threatening of any  proceedings  for that purpose,  and (iii) any request by the
SEC for the amending or supplementing of such registration statement, prospectus
or prospectus supplement.
<PAGE>

                  (b) Use its best  efforts to prevent the issuance of any order
suspending the effectiveness of the Shelf Registration Statement or of any order
preventing  or  suspending   the  use  of  the   Prospectus  or  suspending  the
qualification (or exemption from qualification) of any of the Warrant Shares for
sale in any jurisdiction and, if any such order is issued, to use its reasonable
best  efforts  to obtain  the  withdrawal  of any such  order or  suspension  of
qualification or exemption from qualification at the earliest practicable time.

                  (c) Furnish to each  selling  Holder of Warrant  Shares and to
any underwriter  participating  in such  registration at the sole expense of the
Company  at  least  one  conformed  copy  of the  Shelf  Registration  Statement
including  financial  statements and schedules  thereto and each  post-effective
amendment thereto and, if requested,  all documents incorporated or deemed to be
incorporated  therein by reference and all exhibits as soon as practicable after
such Holder or underwriter so requests.

                  (d) Deliver to each  selling  Holder of Warrant  Shares and to
any underwriter  participating  in such  registration at the sole expense of the
Company as many copies of the  Prospectus  (including  each form of  preliminary
prospectus)  and  each  amendment  or  supplement   thereto  and  any  documents
incorporated by reference  therein as such Holder may reasonably  request;  and,
subject to the last  paragraph of this  Section 14, the Company  consents to the
use of such  Prospectus and each amendment or supplement  thereto by each of the
selling  Holders of Warrant Shares and the  underwriters,  if any, in connection
with the offering and sale of the Warrant Shares covered by such  Prospectus and
any amendment or supplement thereto.

                  (e)  Prior  to the  effectiveness  of the  Shelf  Registration
Statement  and  thereafter,  to use its  reasonable  best efforts to register or
qualify,  and to  cooperate  with the  selling  Holders  of  Warrant  Shares  in
connection  with the  registration  or  qualification  (or  exemption  from such
registration or  qualification)  of such Warrant Shares for offer and sale under
the securities or blue sky laws of such  jurisdictions  within the United States
as any  selling  Holder  reasonably  requests;  keep each such  registration  or
qualification  (or exemption  therefrom)  effective  during the period the Shelf
Registration Statement is required to be kept effective and do any and all other
acts or things  reasonably  necessary or advisable to enable the  disposition in
such  jurisdictions  of the  Warrant  Shares  covered by the Shelf  Registration
Statement;  provided,  however,  that the  Company  shall not be required to (i)
qualify to do  business  in any  jurisdiction  where it would not  otherwise  be
required to qualify but for this Section  14(e),  (ii) subject itself to general
taxation in any such  jurisdiction,  (iii) file a general  consent to service of
process in any such  jurisdiction,  (iv) provide any undertakings that cause the
Company  material  expense or burden,  or (v) make any change in its  charter or
by-laws,  which in each case the Company's  Board of Directors  determines to be
contrary to the best interests of the Company and its stockholders.

                  (f) Cooperate  with the selling  Holders of Warrant  Shares to
facilitate  the timely  preparation  and delivery of  certificates  representing
Warrant Shares to be sold,  which  certificates  shall not bear any  restrictive
legends  and shall be in a form in  compliance  with any  applicable  rules of a
stock exchange on which the Common Stock is then listed; and enable such Warrant
Shares to be in such  denominations  and registered in such names as Holders may
reasonably request.

                  (g)  Upon  the  occurrence  of any  event  or any  information
becoming  known to the  Company  that  makes  any  statement  made in the  Shelf

<PAGE>

Registration  Statement or the Prospectus or any document incorporated or deemed
to be  incorporated  therein by  reference  untrue in any material  respect,  as
promptly as  practicable  prepare and file with the SEC, at the sole  expense of
the Company, a supplement or post-effective  amendment to the Shelf Registration
Statement or a supplement  to the  Prospectus  or any document  incorporated  or
deemed to be  incorporated  therein  by  reference,  or file any other  required
document so that,  as  thereafter  delivered  to the  purchasers  of the Warrant
Shares being sold  thereunder,  any such  Prospectus  will not contain an 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.

                  (h) Prepare and file with the SEC,  promptly  upon the request
of any Holder, any amendments or supplements to the Shelf Registration Statement
or  prospectus  which,  in the judgment of counsel for the Company,  is required
under the  Securities  Act in connection  with the  distribution  of the Warrant
Shares by such Holders.

                  (i) Comply with all  applicable  rules and  regulations of the
SEC and make generally  available to its security  holders  earnings  statements
satisfying  the  provisions of Section 11(a) of the  Securities Act and Rule 158
thereunder (or any similar rule  promulgated  under the Securities Act) no later
than 90 days after the end of any 12-month  period (or 120 days after the end of
any 12-month period if such period is a fiscal year) commencing on the first day
of the first fiscal quarter of the Company after the effective date of the Shelf
Registration Statement, which statements shall cover said 12-month periods.

                  (j) Cooperate  with each seller of Warrant  Shares  covered by
the Shelf  Registration  Statement in connection with any filings required to be
made with the National Association of Securities Dealers, Inc.

                  (k) Use its  reasonable  best  efforts  to  cause,  at its own
expense,  all Warrant Shares relating to the Shelf Registration  Statement to be
listed on each  securities  exchange,  if any,  or  quoted on any  broker-dealer
quotation  system on which  similar  securities  issued by the  Company are then
listed.

                  (l) Furnish an opinion,  dated as of the effective date of the
Shelf Registration  Statement,  of the counsel  representing the Company for the
purpose of such registration addressed to the underwriters,  if any, making such
request,  covering such matters as are customarily  covered by such opinions and
as such underwriters may reasonably request.  Use its reasonable best efforts to
furnish  letters  dated  as of the  effective  date  of the  Shelf  Registration
Statement,   from  independent  certified  public  accountants  of  the  Company
addressed  to the  underwriters,  if any,  making such  request,  covering  such
matters as are customarily  covered by such letters and as such underwriters may
reasonably request.

         The Company may require  each seller of Warrant  Shares as to which any
registration  is being  effected  to furnish  to the  Company  such  information
regarding such seller and the distribution of such Warrant Shares as the Company
may, from time to time,  reasonably  request.  The Company may exclude from such
registration  the Warrant  Shares of any seller so long as such seller  fails to
furnish such information  within a reasonable time after receiving such request.
Each  seller as to which  the Shelf  Registration  Statement  is being  effected
agrees to  furnish  promptly  to the  Company  all  information  required  to be
disclosed in order to make the information  previously  furnished to the Company
by such seller not materially misleading.
<PAGE>

         Each Holder of Warrant Shares  understands  that the Securities Act may
require  delivery of the Prospectus in connection with any sale thereof pursuant
to the Shelf Registration Statement,  and each such Holder shall comply with the
applicable  Prospectus delivery requirements of the Securities Act in connection
with any such sale.

         Each Holder of Warrant  Shares  agrees by  acquisition  of such Warrant
Shares that, upon actual receipt of any notice from the Company of the happening
of  any  event  of  the  kind  described  in  Section  14(a)(ii)  hereof  or any
information   becoming  known  that  makes  any  statement  made  in  the  Shelf
Registration  Statement or the Prospectus or any document incorporated or deemed
to be incorporated  therein by reference  untrue in any material  respect,  such
Holder will forthwith discontinue  disposition of such Warrant Shares covered by
the Shelf  Registration  Statement or the  Prospectus  to be sold by such Holder
until  such  Holder's  receipt  of the  copies of the  supplemented  or  amended
Prospectus  contemplated  by  Section  14(d)  hereof,  or until it is advised in
writing  (the  "Advice") by the Company  that the use of the  Prospectus  may be
resumed,  and has received copies of any amendments or supplements  thereto.  In
the event the Company shall give any such notice, the Registration  Period shall
be extended by the number of days during such period from and including the date
of the  giving of such  notice  to and  including  the date when each  seller of
Warrant Shares covered by the Shelf Registration  Statement, as the case may be,
shall have  received (i) the copies of the  supplemented  or amended  Prospectus
contemplated by Section 14(d) hereof or (ii) the Advice.

         15. Expenses. With respect to such registration, the Company shall bear
all fees, costs and expenses,  including  without  limitation all  registration,
filing and NASD fees,  printing expenses,  fees and disbursements of counsel and
accountants for the Company,  all internal Company expenses,  and all legal fees
and  disbursements and other expenses of complying with state securities or blue
sky laws of any jurisdiction in which the Warrant Shares are to be registered or
qualified, but excluding any underwriting discounts and commissions and transfer
taxes and any other related selling  expenses  incurred by the selling  Holders.
The selling  Holders  will be  responsible  for fees and  disbursements  of such
parties' counsel and accountants.

         16.  Indemnification By the Company. With respect to such registration,
the Company will indemnify and hold harmless each Holder of Warrant Shares which
are included in a  registration  statement  pursuant to the  provisions  of this
Warrant,  its  directors and officers,  and any  underwriter  (as defined in the
Securities  Act) for such  Holders and each person,  if any,  who controls  such
Holder or such  underwriter  within the meaning of the Securities  Act, from and
against,   and  will  reimburse  such  Holder  and  each  such  underwriter  and
controlling person with respect to, any and all loss, claim, damage,  liability,
cost (including  without  limitation the reasonable cost of investigation of any
claim)  and  expense,  joint  or  several,  to  which  such  Holder  or any such
underwriter or controlling person may become subject under the Securities Act or
otherwise,  insofar  as such  losses,  claims,  damages,  liabilities,  costs or
expenses arise out of or are based on (i) any untrue statement or alleged untrue
statement of any material fact  contained in such  registration  statement,  any
prospectus contained therein or any amendment or supplement thereto, or (ii) the
omission or alleged  omission to state  therein a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances in which they were made, not misleading; or (iii) any violation or
alleged  violation by the Company of the Exchange Act, any state securities law,
or any rule or regulation promulgated under any of the aforementioned  statutes,
provided,  however,  that the Company will not be liable in any such case to the
extent that any such loss, claim, damage,  liability, cost or expense arises out

<PAGE>

of or is based upon any untrue statement or alleged untrue statement or omission
or alleged  omission so made in conformity  with  information  furnished by such
Holder, such underwriter or such controlling person in writing  specifically for
use in the preparation thereof.


         17. Indemnification By Holders. With respect to such registration, each
Holder of Warrant Shares which are included in a registration statement pursuant
to the  provisions of this Warrant will,  jointly and  severally,  indemnify and
hold harmless the Company,  its directors and officers and each person,  if any,
who  controls the Company  within the meaning of the  Securities  Act,  from and
against,  and will reimburse the Company and each such controlling  person, with
respect to, any and all loss, claim, damage,  liability, cost (including without
limitation the reasonable cost of investigation of any claim) and expense, joint
or  several,  to which the  Company  or any such  controlling  person may become
subject under the Securities Act or otherwise,  insofar as such losses,  claims,
damages, liabilities, costs or expenses arise out of (i) any untrue statement or
alleged  untrue  statement of any material fact  contained in such  registration
statement,  any  prospectus  contained  therein or any  amendment or  supplement
thereto  made  in  conformity   with   information   furnished  by  such  Holder
specifically for use in the preparation thereof, or (ii) the omission or alleged
omission  to state  therein a material  fact  required  to be stated  therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading made in conformity with information  furnished by
such  Holder  specifically  for use in the  preparation  thereof;  or (iii)  any
violation or alleged  violation  by the Company of the  Exchange  Act, any state
securities  law,  or  any  rule  or  regulation  promulgated  under  any  of the
aforementioned statutes,  provided that any such loss, claim, damage, liability,
cost or expense  arises out of or is based upon any untrue  statement or alleged
untrue  statement  or omission or alleged  omission so made in  conformity  with
information  furnished by such Holder  specifically  for use in the  preparation
thereof.

         18.  Rule  144.  From  the  effective  date of the  Shelf  Registration
Statement,  the Company shall use its reasonable  best efforts to timely prepare
and file all  documents  required to be filed with the SEC as shall be necessary
to enable the Holders to sell  unregistered  Warrant  Shares in accordance  with
Rule 144 under the Securities  Act. Upon the request of any Holder,  the Company
shall  deliver to such Holder a written  statement as to whether it has complied
with such requirements.

         19. Anti-Dilution  Provisions.  So long as this Warrant, or any portion
thereof,  shall remain  outstanding and unexpired,  the Exercise Price in effect
from time to time and the number  and kind of  securities  purchasable  upon the
exercise of the  Warrants  shall be subject to  adjustment  from time to time as
follows:

                  (a) If the  Company  shall (i)  declare a  dividend  or make a
distribution  on its  outstanding  shares  of  Common  Stock in shares of Common
Stock, (ii) subdivide or reclassify its outstanding  shares of Common Stock into
a greater  number of shares,  or (iii)  combine or  reclassify  its  outstanding
shares of Common Stock into a smaller number of shares (any of the foregoing,  a
"Dilutive  Event"),  the Exercise Price in effect at the time of the record date
for such  Dilutive  Event  shall be  adjusted  so that it shall  equal the price
determined by multiplying  the Exercise Price by a fraction,  the denominator of
which  shall be the  number of shares of Common  Stock  outstanding  immediately
after giving effect to such Dilutive Event,  and the numerator of which shall be
the  number  of shares of Common  Stock  outstanding  immediately  prior to such
Dilutive Event (such fraction,  the "Adjustment Factor").  Such adjustment shall
be made successively whenever any Dilutive Event shall occur.
<PAGE>

                  (b) If the Company  shall issue rights or warrants to all, but
not less  than  all,  of the  holders  of its  Common  Stock  entitling  them to
subscribe for or purchase shares of Common Stock (or securities convertible into
Common Stock) at a price (or having a conversion  price per share) less than the
Current  Market Price (as defined  below) of the Common Stock on the record date
specified  below,  the  Exercise  Price shall be adjusted so that the same shall
equal  the  price  determined  by  multiplying  the  Exercise  Price  in  effect
immediately  prior to the date of such issuance by a fraction,  the numerator of
which shall be the sum of the number of shares of Common  Stock  outstanding  on
such record date and the number of  additional  shares of Common Stock which the
aggregate  offering  price of the total  number  of  shares  of Common  Stock so
offered (or the  aggregate  conversion  price of the  convertible  securities so
offered)  would  purchase  at the Current  Market  Price per share of the Common
Stock,  and the  denominator  of which  shall be the sum of the of the number of
shares  of  Common  Stock  outstanding  on such  record  date and the  number of
additional  shares of Common Stock offered for subscription or purchase (or into
which the convertible  securities so offered are  convertible).  Such adjustment
shall be made successively whenever such rights or warrants are issued and shall
become  effective  immediately  after the record date for the  determination  of
stockholders entitled to receive such rights or warrants; and to the extent that
shares of Common Stock are not delivered (or securities  convertible into Common
Stock are not delivered)  after the  expiration of such rights or warrants,  the
Exercise  Price shall be readjusted to the Exercise Price which would then be in
effect had the  adjustments  made upon the  issuance  of such rights or warrants
been  made  upon the basis of  delivery  of only the  number of shares of Common
Stock (or securities  convertible  into Common Stock)  actually  delivered.  The
"Current  Market Price" per share of Common Stock at any date shall be deemed to
be the  average of the daily  closing  prices for the  thirty  (30)  consecutive
business days immediately before such date.

                  (c) Whenever the Exercise  Price payable upon exercise of each
Warrant is  adjusted  pursuant to Section  19(a) or 19(b),  the number of shares
purchasable  upon exercise of this Warrant shall  simultaneously  be adjusted by
dividing  the number of shares  issuable  upon  exercise of this  Warrant by the
Adjustment Factor.

                  (d) If at any time, as a result of an adjustment made pursuant
to this  Section  19(e) or 19(f),  the Holder of this Warrant  shall  thereafter
become entitled to receive any shares of the Company, other than Common Stock or
shares of any issuer other than the Company,  thereafter  the Exercise Price and
the number of such other  shares so  receivable  upon  exercise of this  Warrant
shall be  subject  to  adjustment  from time to time in a manner and on terms as
nearly  equivalent as practicable  to the provisions  with respect to the Common
Stock contained in Sections 19(a), 19(b) and 19(c).

                  (e)  If the  Company  by  reclassification  of  securities  or
otherwise,  shall change any of the securities as to which purchase rights under
this  Warrant  exist into the same or a different  number of  securities  of any
other class or classes,  this Warrant  shall  thereafter  represent the right to
acquire such number and kind of  securities  as would have been  issuable as the
result of such change with  respect to the  securities  that were subject to the
purchase rights under this Warrant immediately prior to such reclassification or
other change and the Exercise Price therefor  shall be  appropriately  adjusted,
all subject to further adjustment as provided in this Section 19.

                  (f) If at any time there shall be (i) a reorganization  (other

<PAGE>

than a  subdivision,  combination,  reclassification,  or other change of shares
otherwise  provided for herein),  (ii) a merger or  consolidation of the Company
with or into  another  corporation  in which the  Company  is not the  surviving
entity,  or a reverse  triangular  merger in which the Company is the  surviving
entity but the shares of the  Company's  capital stock  outstanding  immediately
prior to the merger are  converted by virtue of the merger into other  property,
whether  in the  form of  securities,  cash,  or  otherwise,  or (iii) a sale or
transfer of the  Company's  properties  and assets as, or  substantially  as, an
entirety to any other person,  then, as a part of such  reorganization,  merger,
consolidation,  sale or  transfer,  lawful  provision  shall be made so that the
holder of this Warrant shall  thereafter be entitled to receive upon exercise of
this  Warrant,  during  the  period  specified  herein  and upon  payment of the
Exercise Price then in effect, the number of shares of stock or other securities
or property of the successor  corporation  resulting  from such  reorganization,
merger, consolidation,  sale or transfer that a Holder of the shares deliverable
upon  exercise  of this  Warrant  would  have been  entitled  to receive in such
reorganization, consolidation, merger, sale or transfer if this Warrant had been
exercised immediately before such reorganization, merger, consolidation, sale or
transfer,  all subject to further adjustment as provided in this Section 19. The
foregoing  provisions of this Section 19(f) shall  similarly apply to successive
reorganizations,  consolidations,  mergers, sales and transfers and to the stock
or securities of any other  corporate that are at the time  receivable  upon the
exercise of this Warrant. In all events,  appropriate  adjustment (as determined
by the Company's  Board of Directors)  shall be made in the  application  of the
provisions  of this  Warrant  with  respect to the rights and  interests  of the
Holder after the  transaction,  to the end that the  provisions  of this Warrant
shall be applicable  after the event,  as near as reasonably may be, in relation
to any shares or other  property  deliverable  after that event upon exercise of
this Warrant.

                  (g) Whenever the Exercise  Price shall be adjusted as required
by the  provisions of Section 19, the Company shall promptly file in the custody
of its  Secretary or an Assistant  Secretary  at its  principal  office or Other
Office and with the Warrant Agent, if any, an officer's  certificate showing the
adjusted  Exercise  Price  determined  as  herein  provided,  setting  forth  in
reasonable detail the facts requiring such adjustment,  including a statement of
the number of  additional  shares of Common Stock or other  securities,  if any,
issuable  upon  exercise  of this  Warrant  and  such  other  facts  as shall be
necessary  to show the reason for and the manner of computing  such  adjustment.
Each  such  certificate  shall be made  available  at all  reasonable  times for
inspection by Holder and the Company shall  forthwith after each such adjustment
mail a copy of such  certificate  to Holder at its address last appearing in the
Warrant Register.

         20. Notices to Warrant Holders.  If at any time while this Warrant,  or
any portion thereof,  remains  outstanding and unexpired,  (i) the Company shall
pay any  dividend or make any  distribution  upon the Common  Stock  (other than
regular quarterly cash dividends or dividends paid in the form of Common Stock),
(ii) the  Company  shall  offer to the  holders of Common  Stock  generally  for
subscription  or  purchase  by them any share of the Company of any class or any
other rights issued by the Company,  or (iii) the capital  reorganization of the
Company,  reclassification of the capital stock of the Company, consolidation or
merger  of  the  Company  with  or  into  another  corporation,  sale  of all or
substantially  all  of  the  property  and  assets  of the  Company  to  another
corporation or voluntary or involuntary  dissolution,  liquidation or winding up
of the Company shall be effected, then in any such case, the Company shall cause
to be mailed to Holder at its  address  specified  in the Warrant  Register,  at
least 10 days prior to the date specified in (x) or (y) below, as applicable,  a
notice  containing a brief  description of the proposed event  described in (i),
(ii) or (iii)  above and  stating  the date on which (x) a record is to be taken
for  the  purpose  of  such  dividend,  distribution  or  rights,  or  (y)  such
reclassification,  reorganization,  consolidation,  merger,  sale,  dissolution,
liquidation or winding up is to take place and the date, if any, is be fixed, as

<PAGE>

of which the holders of the Common Stock or other  securities shall receive cash
or other property  deliverable upon such event.  Notwithstanding  the above, the
failure to give such notice shall not affect the validity of any transaction for
which the notice was required to be given.


         21.  Governing  Law. This Warrant shall be governed by and construed in
accordance  with the internal  laws of the State of New York  without  regard to
such state's conflict of law provisions.

         22.  Severability.  In the event that any one or more of the provisions
contained  herein,  or the  application  thereof  in any  circumstance,  is held
invalid, illegal or unenforceable,  the validity, legality and enforceability of
any such  provision  in every  other  respect  and of the  remaining  provisions
contained herein shall not be affected or impaired thereby.

         23.  Standstill.  Mercacorp  and,  if  applicable,  such  other  Holder
acknowledges  that it is a condition  to the  Company's  agreement to issue this
Warrant to Mercacorp that Mercacorp and, if applicable,  such other Holder agree
that it will not, and will direct their  respective  Affiliates and  Associates,
and directors,  officers,  employees and agents of Mercacorp and, if applicable,
such other  Holder  and their  respective  Affiliates  and  Associates,  not to,
directly or indirectly,  for a period beginning on the date hereof and ending on
the first to occur of (i)  November  10,  2001,  or (ii) the  expiration  of the
twelve (12) month  period  immediately  following  the date on which all 750,000
Warrant  Shares have been issued under this Warrant (the  "Standstill  Period"),

         convertible or exercisable  into, or  exchangeable  for,  Common Stock)
         which at any time would result in Mercacorp  and, if  applicable,  such
         other Holder in the aggregate owning, directly or indirectly, more than
         1,650,000 shares of Common Stock;

                  (b) make, or in way  participate  in,  directly or indirectly,
         any  "solicitation"  of "proxies" (as such terms are defined or used in
         Regulation 14A under the Exchange Act) or become a "participant"  in an
         "election  contest"  (as such terms are  defined or used in Rule 14a-11
         under the  Exchange  Act) with respect to the Company or seek to advise
         or  influence  any  person  with  respect  to the  voting of any voting

                  (c)  execute  any  written  consent  in lieu of a  meeting  of
         holders of securities  of the Company or any class thereof  unless such
         written consent is solicited by the Board of Directors of the Company;

                  (d) initiate,  propose or otherwise  solicit  stockholders for
         the approval of one or more  stockholder  proposals with respect to the
         Company as  described in Rule 14a-8 under the Exchange Act or induce or

         or indirectly  participate in or encourage the formation of any "group"
         (within the meaning of Section 13(d)(3) of the Exchange Act) which owns
         or seeks to acquire ownership of voting  securities of the Company,  or
         to acquire or affect control of the Company;

         Board of  Directors of the Company or seek the removal of any member of
         the Board of Directors of the Company;

         with  others,  to seek to  control  or to  influence  in any manner the

         assistance (by loan, capital  contribution or otherwise) or information
         to  any  party  with  respect  to  any  form  of  business  combination
         transaction (including,  without limitation, a merger, consolidation or
         acquisition or disposition of significant  assets of the Company or any
         other  entity)  with  the  Company  or  any  affiliate  thereof  or any
         restructuring,  recapitalization or similar transaction with respect to
         the Company or any affiliate thereof;

                  (i) instigate,  encourage,  assist or render advice to or make
         any  recommendation or proposal to any person or other entity to engage
         in any of the  actions  covered  by  clauses  (a)  through  (h) of this
         Section 23, or render  advice with respect to voting  securities of the
         Company;

                  (j)  except to the  extent  required  by law,  make any public

         information)  with respect to any of the matters covered by clauses (a)
         through  (h) of this  section  23,  or with  respect  to the  terms and
         conditions of, or any of the facts related to, this Warrant; or

                  (k) request any waiver, modification, termination or amendment
         of this Section 23 or the  relinquishment  by the Company of any rights
         with respect thereto.

         For  purposes of this Section 23, the term  "voting  securities"  shall
mean (i) any  securities  which are entitled to vote upon any  matters,  whether
such  securities are entitled to vote on such matters in all events or only upon
the  occurrence  of a  default  or other  contingencies,  or (ii)  any  options,
warrants,  rights or securities  which by their terms may be convertible into or
exchangeable  for any  security  described in clause (i) of this  sentence.  The
restrictions  set forth in this  Section 23 shall  survive  Mercacorp's  and, if
applicable,  such  other  Holder's  exercise  of the last of the Lots and  shall

                               _____________, 1998


LaserSight Incorporated
3300 University Blvd.
Suite 140
Orlando, Florida  32792

         Re:      Warrant Transfer

Gentlemen:

         We have acted as  counsel  to  [Mercacorp,  Inc.  or other  holder] , a
corporation   organized   under  the  laws  of   ________________________   (the
"Company"),  in connection with the transfer of the Warrant,  dated November 11,
1998, to purchase 750,000 shares of common stock, $.001 par value, of LaserSight
Incorporated (the "Warrant") to _________________________ ("Transferee").

         In connection with this opinion,  we have examined originals or copies,
certified or otherwise  identified to our satisfaction,  of the Warrant and such
agreements, instruments, certificates,  representations,  documents and records,
and  have  made  such  other  investigations,  as we have  deemed  necessary  or
appropriate  as a basis  for the  opinions  set  forth  herein.  As to any facts
material to the opinions  expressed  herein, we have relied upon oral or written
statements  and  representations  of officers and other  representatives  of the
Company and Transferee.

         The Transferee has represented that it is acquiring the Warrant (i) for
investment and not for distribution or resale,  and (ii) solely for Transferee's
own account and not as a nominee for any other person.

         Based upon and subject to the foregoing, we are of the opinion that the
transfer  of the  Warrant  from the  Company to  Transferee  is exempt  from the
registration requirements of the Securities Act of 1933 (the "Act").

         We express no  opinion as to the laws of any  jurisdictions  other than
the  Federal  securities  laws of the United  States of America in effect on the
date hereof,  and we assume no obligation  to revise or supplement  this opinion
should such laws be changed by legislative or  administrative  action,  judicial
decision or otherwise.

         This  opinion is solely for the benefit of you and your counsel and can
not be relied upon by any other person, corporation or entity.
