The number of Option Shares and the Exercise Price per share set forth above are
subject to adjustment as provided herein.  Unless otherwise  expressly set forth
herein,  all capitalized  terms used but not otherwise defined herein shall have
respective meanings attributed thereto in Section 13.

      The Langer  Options shall not be evidenced by any  instrument or agreement
apart from this Option Agreement (the "Option Agreement").

1.    Exercise of Langer Options.

      1.1 The Langer  Options may be exercised,  in whole or in part, but not as
to less than 10,000  Langer  Options or, if less,  the number of Langer  Options
evidenced  hereby, on or after the Commencement Date and prior to the Expiration
Time by surrendering this Option Agreement,  with the exercise form provided for
herein  duly  executed  by  the  Holder  or  by  the  Holder's  duly  authorized
attorney-in-fact,  at the principal office of the Company,  presently located at
450 Commack Road,  Deer Park, New York 11729,  or at such other office or agency
in the United  States as the Company may  designate  by notice to the Holder (in
either event, the "Company Offices"),  accompanied by payment in full, either in
the form of cash, wire transfer, bank cashier's check or certified check payable
to the order of the  Company,  of the Exercise  Price  payable in respect of the
Langer  Options  being  exercised.  If fewer than all of the Langer  Options are
exercised,  the Company shall,  upon each exercise prior to the Expiration Time,
execute and deliver to the Holder a new Option  Agreement  (dated as of the date
hereof) and  otherwise  identical  hereto  evidencing  the balance of the Langer
Options that remain exercisable.

      1.2 On the date of exercise  of the Langer  Options,  the Holder  shall be
deemed to have become the holder of record for all purposes of the Option Shares
to which the exercise relates.

      1.3 As soon as practicable,  but not in excess of five (5) days, after the
exercise  of all or part of the Langer  Options,  the  Company,  at its  expense
(including  the payment by it of any applicable  issue taxes),  will cause to be
issued in the name of and delivered to the Holder a certificate or  certificates
evidencing  the  number  of duly  authorized,  validly  issued,  fully  paid and
nonassessable  Option  Shares to which the Holder  shall be  entitled  upon such
exercise,  provided  that the  Company  shall not be  required  to pay any taxes
payable as a result of the issuance of any certificate or certificates in a name
other than that of the Holder,  in which case the Company  shall not be required
to issue or deliver  such  certificate(s)  unless or until the person or persons
requesting  issuance  thereof  shall have paid to the Company the amount of such
tax or shall have  established to the  satisfaction of the Company that such tax
has been paid.

      1.4 Each certificate  representing Option Shares obtained upon exercise of
a Langer  Option shall bear a legend as follows  unless such Option  Shares have
been  registered  under the Act and the issuance  complies  with any  applicable
state securities laws:


                                      -2-


            "The  securities  represented by this  certificate  have
            been   acquired  for   investment   and  have  not  been
            registered  under the Securities Act of 1933, as amended
            (the "Act").  The securities may not be sold,  assigned,
            pledged,  hypothecated or otherwise  transferred  except
            pursuant to an effective  registration  statement  under
            the  Act  and  in  compliance  with   applicable   state
            securities  laws, or the Company  receives an opinion of
            counsel,  reasonably  satisfactory to the Company,  that
            such  registration  is not  required  and that the sale,
            assignment,  pledge,  hypothecation  or  transfer  is in
            compliance with applicable state securities laws."

2.    Issuance of Common Stock; Reservation of Shares.

      2.1 The Company covenants and agrees that it will at all times reserve and
keep available, free and clear from preemptive rights, out of its authorized but
unissued  Common Stock,  solely for the purpose of issuance upon the exercise of
Langer  Options as provided  herein,  such number of shares of Option  Shares as
shall then be issuable upon the exercise of all Langer Options then outstanding.

      2.2 The Company  covenants  and agrees that all Option  Shares that may be
issued  upon  the  exercise  of all or part of the  Langer  Options  will,  upon
issuance  in  accordance  with the terms  hereof,  be duly  authorized,  validly
issued,  fully paid and nonassessable and free from all taxes, liens and charges
with respect to the issue thereof.

      2.3 The Company further  covenants and agrees that if any shares of Common
Stock reserved for the purpose of the issuance of Option Shares upon exercise of
the Langer Options require  registration  with, or approval of, any governmental
authority  under any  federal  or state law  before  such  shares may be validly
issued or delivered upon  exercise,  then the Company will promptly use its best
efforts to effect such registration or obtain such approval, as the case may be.

3.    Adjustments of Exercise Price and Number and Character of Shares  Issuable
      Upon Exercise.

      3.1  Upon  each  adjustment  of the  Exercise  Price  as a  result  of the
calculations  made in this  Section,  this  Option  Agreement  shall  thereafter
evidence the right to receive,  at the adjusted  Exercise Price,  that number of
Option Shares (calculated to the nearest one-hundredth) obtained by dividing (i)
the  product of the  aggregate  number of Option  Shares  covered by this Option
Agreement  immediately prior to such adjustment and the Exercise Price in effect
immediately  prior to such adjustment of the Exercise Price by (ii) the Exercise
Price in effect immediately after such adjustment of the Exercise Price.

      3.2 The  Exercise  Price will be  adjusted  from time to time as  provided
herein.


                                      -3-


            3.2.1 Extraordinary Dividends and Distributions. In case the Company
      at any time or from time to time  after  the date  hereof  shall  declare,
      order, pay or make a dividend or other  distribution  (including,  without
      limitation,  any  distribution  of  other  or  additional  stock  or other
      securities  or  property  or  options  by way  of  dividend  or  spin-off,
      reclassification,  recapitalization or similar corporate rearrangement) on
      the Common Stock other than (a) a dividend payable in additional shares of
      Common Stock or (b) a regularly  scheduled  cash  dividend  payable out of
      consolidated  earnings or earned  surplus,  determined in accordance  with
      generally accepted accounting principles, then, in each such case, subject
      to Section  3.3,  the Exercise  Price in effect  immediately  prior to the
      close of  business  on the  record  date  fixed for the  determination  of
      holders of any class of  securities  entitled to receive such  dividend or
      distribution  shall be reduced,  effective  as of the close of business on
      such record date, to a price determined by multiplying such Exercise Price
      by a fraction

                  (a) the  numerator of which shall be the Current  Market Price
            in effect on such record date or, if the Common  Stock  trades on an
            ex-dividend  basis,  on  the  date  prior  to  the  commencement  of
            ex-dividend   trading,   less  the  amount  of  such   dividend   or
            distribution  (as determined in good faith by the Board of Directors
            of the Company) applicable to one share of Common Stock, and

                  (b) the  denominator  of which  shall be such  Current  Market
            Price.

            3.2.2 Treatment of Stock Dividends,  Stock Splits,  etc. In case the
      Company  at any time or from  time to time  after  the date  hereof  shall
      declare or pay any dividend on the Common Stock  payable in Common  Stock,
      or shall effect a subdivision  of the  outstanding  shares of Common Stock
      into a greater  number of shares of Common Stock (by  reclassification  or
      otherwise  than by payment of a dividend in Common  Stock),  then,  and in
      each such case,  the  Exercise  Price in effect  immediately  prior to the
      payment of such dividend or the  consummation  of such  subdivision  shall
      concurrently  with the  effectiveness  of such dividend or  subdivision be
      proportionately decreased.

            3.2.3  Adjustments  for  Combinations,  etc. In case the outstanding
      shares  of  Common   Stock   shall  be  combined   or   consolidated,   by
      reclassification  or  otherwise,  into a lesser number of shares of Common
      Stock, the Exercise Price in effect  immediately prior to such combination
      or  consolidation  shall,  concurrently  with  the  effectiveness  of such
      combination or consolidation, be proportionately increased.

      3.3 De  Minimis  Adjustments.  If the  amount  of  any  adjustment  of the
Exercise Price per share required  pursuant to this Section 3 would be less than
$.02,  such amount shall be carried  forward and adjustment with respect thereto
made at the time of and together with any subsequent  adjustment which, together
with such  amount and any other  amount or amounts  so  carried  forward,  shall
aggregate  a  change  in the  Exercise  Price of at least  $.02 per  share.  All
calculations  under this Option Agreement shall be made to the nearest .001 of a
cent or to the nearest one-hundredth of a share, as the case may be.

      3.4 Abandoned Dividend or Distribution. If the Company shall take a record
of the holders of its Common Stock for the purpose of entitling  them to receive
a dividend or


                                      -4-


other  distribution  (which results in an adjustment to the Exercise Price under
the terms of this  Option  Agreement)  and shall,  thereafter,  and before  such
dividend or distribution is paid or delivered to shareholders  entitled thereto,
legally abandon its plan to pay or deliver such dividend or  distribution,  then
any  adjustment  made to the Exercise Price and number of shares of Common Stock
purchasable  upon exercise of the Langer Options by reason of the taking of such
record shall be reversed, and any subsequent  adjustments,  based thereon, shall
be recomputed.

      3.5  Adjustments To Exercise  Price and Number of Shares.  Notwithstanding
any  adjustment  in the  Exercise  Price or in the  number  or kind of shares of
Common  Stock  purchasable  upon  exercise  of the  Langer  Options,  any Option
Agreement  theretofore  or  thereafter  executed and  delivered  may continue to
express the same number and kind of shares of Common Stock as are stated in this
Option Agreement, as initially issued.

      3.6 Fractional Shares.  Notwithstanding any adjustment pursuant to Section
3 in the number of shares of Common  Stock  covered by this Option  Agreement or
any other provision of this Option Agreement,  the Company shall not be required
to issue  fractions of shares upon  exercise of Langer  Options or to distribute
certificates which evidence fractional shares. In lieu of fractional shares, the
Company  shall make  payment to the  Holder,  at the time of  exercise of Langer
Options  as  herein  provided,  in an  amount  in cash  equal  to such  fraction
multiplied by the Current Market Price of a share of Common Stock on the date of
exercise of Langer Options.

4.    Consolidation, Merger, etc.

      4.1 Adjustments for Consolidation, Merger, Sale of Assets, Reorganization,
etc. In case the Company  after the date  hereof (a) shall  consolidate  with or
merge  into any  other  Person  and  shall not be the  continuing  or  surviving
corporation  of such  consolidation  or  merger,  or (b) shall  permit any other
Person to  consolidate  with or merge into the Company and the Company  shall be
the continuing or surviving Person but, in connection with such consolidation or
merger,  the Common Stock or Other Securities shall be changed into or exchanged
for stock or other securities of any other Person or cash or any other property,
or (c) shall  transfer all or  substantially  all of its properties or assets to
any  other   Person,   or  (d)  shall   effect  a  capital   reorganization   or
reclassification  of the Common Stock or Other Securities  (other than a capital
reorganization or  reclassification  resulting in the issue of additional shares
of Common  Stock for which  adjustment  in the  Exercise  Price is  provided  in
Section 3.2.1), then, and in the case of each such transaction, proper provision
shall be made so that,  upon the basis and the terms and in the manner  provided
in this Option Agreement, the Holder of this Option Agreement, upon the exercise
of a Langer Option at any time after the consummation of such transaction, shall
be  entitled  to  receive  the kind and  amount  of  shares  of stock  and other
securities and property receivable upon such consolidation,  merger, transfer or
recapitalization,  by a holder of the number of  securities  of the  Company for
which a Langer  Option  might  have  been  exercised  immediately  prior to such
consolidation,  merger,  transfer  or  recapitalization.  This  provision  shall
similarly apply to successive consolidations, mergers or recapitalizations.


                                      -5-


      4.2 Assumption of Obligations.  Notwithstanding anything contained in this
Option  Agreement  to the  contrary,  the  Company  shall not  effect any of the
transactions  described in clauses (a) through (d) of Section 4.1 unless,  prior
to the consummation  thereof,  each Person (other than the Company) which may be
required to deliver any stock, securities, cash or property upon the exercise of
Langer Options as provided herein shall assume, by written instrument  delivered
to, and reasonably satisfactory to, the Holder of this Option Agreement, (a) the
obligations of the Company under this Option Agreement (and if the Company shall
survive  the  consummation  of such  transaction,  such  assumption  shall be in
addition to, and shall not release the Company from, any continuing  obligations
of the Company under this Option Agreement) and (b) the obligation to deliver to
the Holder such shares of stock, securities,  cash or property as, in accordance
with the  foregoing  provisions of this Section 4, the Holder may be entitled to
receive.

5.    No Dilution or Impairment.

      The Company shall not, by amendment of its certificate of incorporation or
through  any  consolidation,   merger,   reorganization,   transfer  of  assets,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the  observance or  performance of any of the terms of this Option
Agreement, but will at all times in good faith assist in the carrying out of all
such  terms  and in the  taking  of  all  such  action  as may be  necessary  or
appropriate  in order to protect  the rights of the Holder  against  dilution or
other impairment.  Without limiting the generality of the foregoing, the Company
(a) shall not permit the par value of any  shares of stock  receivable  upon the
exercise of Option  Agreement to exceed the amount  payable  therefor  upon such
exercise,  (b) shall take all such action as may be necessary or  appropriate in
order  that  the  Company   may  validly  and  legally   issue  fully  paid  and
nonassessable  shares of stock, free from all taxes, liens,  security interests,
encumbrances,  preemptive  rights  and  charges  on the  exercise  of the Langer
Options  from time to time  outstanding  and (c) shall not take any action which
results in any adjustment of the Exercise Price if the total number of shares of
Common Stock (or Other  Securities)  issuable after the action upon the exercise
of all of the Langer  Options  would exceed the total number of shares of Common
Stock (or Other  Securities)  then  authorized by the Company's  certificate  of
incorporation and available for the purpose of issue upon such exercise.

6.    Registration Rights.

      Reference is hereby made to that  certain  Registration  Rights  Agreement
pertaining  to  the  Option  Shares  dated  as of  the  Commencement  Date  (the
"Registration  Rights  Agreement")  between the  Company and Holder.  Holder may
assign  its  rights  and  benefits  in,  to and under  the  Registration  Rights
Agreement to any Holder in accordance with the terms of such agreement.


                                      -6-


7.    Replacement of Securities.

      Upon receipt by the Company of evidence  reasonably  satisfactory to it of
the loss,  theft,  destruction  or  mutilation  of this Option  Agreement and of
reasonably satisfactory indemnification,  the Company shall promptly execute and
deliver to the Holder a new Option  Agreement  of like tenor and date.  Any such
new Option  Agreement  executed and  delivered as a result of such loss,  theft,
mutilation or destruction shall constitute an additional  contractual obligation
on the part of the Company.

8.    Registration.

      This  Option  Agreement,  as well as all other  Option  Agreements  issued
pursuant  hereto shall be numbered and shall be  registered  in a register  (the
"Option  Register")  maintained at the Company  Offices as they are issued.  The
Option  Register  shall  list the name,  address  and Social  Security  or other
Federal  Identification  Number,  if any, of all Holders.  The Company  shall be
entitled to treat the Holder as set forth in the Option Register as the owner in
fact of the Langer  Options as set forth  therein for all purposes and shall not
be bound to recognize any equitable or other claim to or interest in such Langer
Options  on the part of any  other  person,  and  shall  not be  liable  for any
registration  of  transfer  of  Langer  Options  that  are  registered  or to be
registered in the name of a fiduciary or the nominee of a fiduciary  unless made
with the actual  knowledge that a fiduciary or nominee is committing a breach of
trust in requesting  such  registration  of transfer,  or with such knowledge of
such facts that its participation therein amounts to bad faith.

9.    Transfer.

      9.1  Permissible  Transferees.  This  Option  Agreement  and the  right to
purchase Langer Options evidenced hereby may be transferred,  sold,  assigned or
hypothecated  in whole or in part, at any time,  or from time to time,  provided
that the Company shall not be required to issue Option Agreements as a result of
any transfer  granting the Holder the right to purchase  less than 10,000 Option
Shares.  Any such transfer shall be effected by executing the form of assignment
at the end hereof,  and (ii) surrendering this Option Agreement for cancellation
to the  Company;  whereupon  the  Company  shall  issue,  in the  name or  names
specified by Holder a new Option  Agreement or Option  Agreements  of like tenor
and  representing in the aggregate  rights to purchase the same number of shares
of Common Stock as are purchasable hereunder.

      9.2 Transfer of Option. The registered Holder of this Option Agreement, by
its acceptance hereof, agrees that it will not sell, assign, pledge, hypothecate
or otherwise  transfer  this Option  Agreement or the Langer  Options  evidenced
hereby  except (i)  pursuant to an effective  registration  under the Act and in
compliance with applicable  state  securities laws, (ii) if the Company receives
an  opinion  of  counsel,  reasonably  satisfactory  to the  Company,  that such
registration   is  not   required  and  that  the  sale,   assignment,   pledge,
hypothecation  or transfer is in compliance  with  applicable  state  securities
laws;  or (iii) to family  members of the Holder or trusts  established  for the
benefit of family members of the Holder.


                                      -7-


10.   Exchange.

      This Option  Agreement  may be exchanged for another  Option  Agreement or
Option  Agreements  entitling  the Holder  thereof to purchase a like  aggregate
number of Option Shares as the Langer  Options  evidenced  hereby,  provided the
Company  shall not be required to issue as a result of any request for  exchange
an Option  Agreement  granting the Holder the right to purchase less than 10,000
Option Shares.  A Holder  desiring to exchange this Option  Agreement shall make
such  request in writing  delivered  to the Company,  and shall  surrender  this
Option Agreement therewith.  Thereupon, the Company shall execute and deliver to
the person entitled thereto a new Option Agreement or Option Agreements,  as the
case may be, as so requested.

11.   Notices.

      11.1 In the event of:

            (a) any  taking by the  Company  of a record of the  holders  of any
      class of securities for the purpose of determining the holders thereof who
      are  entitled to receive any  dividend  (other than a regularly  scheduled
      cash  dividend  payable out of  consolidated  earnings or earned  surplus,
      determined in accordance with generally accepted accounting principles, in
      an amount not  exceeding  the  amount of the  immediately  preceding  cash
      dividend for such period) or other distribution, or any right to subscribe
      for, purchase or otherwise acquire any shares of stock of any class or any
      other securities or property, or to receive any other right, or

            (b) any capital  reorganization of the Company, any reclassification
      or recapitalization of the capital stock of the Company, any consolidation
      or merger  involving the Company and any other Person,  any transaction or
      series of transactions in which more than 50% of the voting  securities of
      the Company are  transferred to another Person,  or any transfer,  sale or
      other disposition of all or substantially all the assets of the Company to
      any other Person, or

            (c)  any  voluntary  or  involuntary  dissolution,   liquidation  or
      winding-up of the Company, then, in either case, the Company shall mail to
      each Holder a notice specifying (i) the date or expected date on which any
      such record is to be taken for the purpose of such dividend,  distribution
      or right,  and the amount and character of such dividend,  distribution or
      right,   and  (ii)  the  date  or   expected   date  on  which   any  such
      reorganization, reclassification, recapitalization, consolidation, merger,
      transfer, sale, disposition,  dissolution, liquidation or winding-up is to
      take place and the time, if any such time is to be fixed,  as of which the
      holders of record of Common Stock (or Other  Securities) shall be entitled
      to exchange  their  shares of Common Stock (or Other  Securities)  for the
      securities  or  other  property   deliverable  upon  such  reorganization,
      reclassification, recapitalization, consolidation, merger,


                                      -8-


      transfer,  dissolution,  liquidation or  winding-up.  Such notice shall be
      mailed at least 15 days prior to the date therein specified.

      11.2 In each  case of any  adjustment  or  readjustment  in the  shares of
Common  Stock (or Other  Securities)  issuable  upon the  exercise of the Langer
Options,  the Company at its expense shall promptly  compute such  adjustment or
readjustment  in  accordance  with the  terms of this  Agreement  and  prepare a
certificate,  signed by the Chairman of the Board,  President or one of the Vice
Presidents of the Company,  and by the Chief Financial Officer, the Treasurer or
one of the Assistant Treasurers of the Company, setting forth such adjustment or
readjustment and showing in reasonable detail the method of calculation  thereof
and the facts upon which such adjustment or  readjustment is based,  including a
statement  of the number of shares of Common Stock  outstanding  or deemed to be
outstanding, and the Exercise Price in effect immediately prior to such issue or
sale and as  adjusted  and  readjusted  (if  required  by  Section 3) on account
thereof.  The Company shall  forthwith  mail a copy of each such  certificate to
each holder of a Langer Option and shall,  upon the written  request at any time
of any  holder of a Langer  Option,  furnish to such  holder a like  certificate
setting forth the Exercise Price at the time in effect and showing in reasonable
detail how it was  calculated.  The  Company  shall also keep copies of all such
certificates  at its  principal  office and shall cause the same to be available
for  inspection at such office during normal  business  hours by any holder of a
Langer Option or any prospective  purchaser of a Langer Option designated by the
holder thereof.

      11.3 All notices and other  communications  hereunder  shall be in writing
and shall be deemed given when  delivered  in person,  against  written  receipt
therefor, or two days after being sent, by registered or certified mail, postage
