Exhibit 4.12

THIS  WARRANT  AND THE  SHARES  ISSUABLE  UPON  EXERCISE  HEREOF  HAVE  NOT BEEN
REGISTERED  OR QUALIFIED FOR SALE UNDER THE  SECURITIES  ACT OF 1933, AS AMENDED
(THE "ACT"),  OR ANY STATE  SECURITIES LAW AND MAY NOT BE SOLD OR TRANSFERRED IN
THE ABSENCE OF SUCH  REGISTRATION,  UNLESS THE COMPANY IS  REASONABLY  SATISFIED
THAT  THE   PROPOSED   SALE  OR  TRANSFER  IS  EXEMPT  FROM  SUCH   REGISTRATION
REQUIREMENTS.


                           WARRANT TO PURCHASE SHARES
                                       OF
                              CLASS A COMMON STOCK
                              --------------------

                           Void after January 12, 2012

     THIS IS TO CERTIFY  that, as of this 12th day of January,  2007,  for value
received  and subject to the  provisions  hereinafter  set forth,  Roaring  Fork
Capital  SBIC,  L. P.  (the  "Purchaser"),  is  entitled  to  purchase  from ATC
Healthcare,  Inc., a Delaware corporation (the "Company"),  at any time from the
date hereof to and  including  January 12, 2012 (the  "Expiration  Date"),  at a
price  initially  equal to  Forty-five  Cents  ($0.45)  per share (the  "Warrant
Calculation  Price"),  One Million  (1,000,000) (the "Warrant Number") shares of
the Class A Common Stock of the Company (the "Stock").

     The aggregate price for the shares of Stock purchasable  hereunder shall be
equal to the  initial  Warrant  Calculation  Price  multiplied  by the number of
shares initially purchasable hereunder. Such aggregate price is herein sometimes
referred to as the "Aggregate Warrant Price". The Warrant  Calculation Price per
share is, however, subject to adjustment as hereinafter provided (such price, or
such price as last adjusted, as the case may be, being herein referred to as the
"Per Share Warrant Price"). The Warrant Number is likewise subject to adjustment
as hereinafter provided.

1. EXERCISE OF WARRANT.  Subject to the conditions  hereinafter set forth,  this
Warrant may be exercised in whole at any time,  or in part from time to time, by
the holder hereof, by delivery of a written notice in the form at the end hereof
(the "Exercise  Notice") duly executed at the principal office of the Company in
Lake  Success,  New York or at such other office as the Company may designate by
written  notice to the holder hereof within the  above-mentioned  period and, at
the  election  of the  holder,  either by paying to the  Company  the  Aggregate
Warrant Price (or the  proportionate  part thereof if exercised in part) for the
shares so purchased  in current  funds,  in which case payment  shall be made in
cash, by wire transfer,  or by certified or official bank check,  or by cashless
exercise as hereinafter  set forth.  The holder shall not be required to deliver
the  original  Warrant in order to effect an  exercise  of the  Warrant.  At its
option, the holder may request, pursuant to Section 1, that the Company exchange
this  Warrant for a  particular  number of shares  subject to the  Warrant  (the
"Converted Warrant Shares") by delivering to the holder,  without payment by the
holder of the Warrant Price or any cash or other  consideration,  that number of
shares of Stock as is equal to the  quotient  obtained by dividing the Net Value
(as  hereinafter  defined) of the  Converted  Warrant  Shares by the Fair Market
Value (as determined (i) by reference to the current market price based upon the
average last sale price for the three  business  days prior to exercise,  if the
Stock is publicly traded or (ii) by the Board of Directors  acting in good faith
if the Stock is not publicly  traded) of a single share of Stock,  determined in
each case as of the close of business  on the date of exercise of this  Warrant.
The  "Net  Value"  of the  Converted  Warrant  Shares  shall  be  determined  by
subtracting the Aggregate Warrant Price of the Converted Warrant Shares from the
aggregate  Fair  Market  Value  of  the  Converted  Warrant  Shares.  All  other
provisions  of the  Warrants  shall apply to any such  exchange of the  Warrants
pursuant to the terms of this Section 1.

Company's Failure to Timely Deliver Securities.  If within ten (10) Trading Days
after the  Company's  receipt of the  facsimile  copy of an Exercise  Notice the
Company shall fail to issue and deliver a certificate to the holder and register
such  shares of Common  Stock on the  Company's  share  register  or credit  the
holder's  balance  account  with DTC for the number of shares of Common Stock to
which the holder is entitled  upon the  holder's  exercise  hereunder,  and such
failure to issue and deliver such  certificate(s)  continues  for more than five
(5) Business Days after the Company receives written notice of non-delivery from
the holder  (with the total  period of time of the 10  Trading  Day period and 5
Business Day period  referenced  herein being  referred to as the "Cure Period")
and if on or after the expiration of the Cure Period without the delivery of the
applicable  certificate(s),  the holder purchases (in an open market transaction
or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the
holder of shares of Common Stock  issuable  upon such  exercise  that the holder
anticipated  receiving  from the Company (a "Buy-In"),  then the Company  shall,
within  three (3) Business  Days after the holder's  request and in the holder's
discretion, either (i) pay cash to the holder in an amount equal to the holder's
total purchase price (including brokerage commissions, if any) for the shares of
Common Stock so purchased  (the "Buy-In  Price"),  at which point the  Company's
obligation  to deliver  such  certificate  (and to issue  such  shares of Common
Stock) shall terminate,  or (ii) promptly honor its obligation to deliver to the
Holder a certificate or  certificates  representing  such shares of Common Stock
and pay cash to the  Holder in an  amount  equal to the  excess  (if any) of the
Buy-In  Price  over the  product of (A) such  number of shares of Common  Stock,
times (B) the dollar volume Weighted Average Price on the date of exercise.

If this Warrant is exercised in respect of fewer than all of the shares of Stock
at the time  purchasable  hereunder,  the holder  hereof  shall be  entitled  to
receive a new  Warrant  covering  the  number of shares in respect of which this
Warrant shall not have been  exercised  and setting forth the Aggregate  Warrant
Price  applicable to such shares.  Notwithstanding  anything to the contrary set
forth herein,  this Warrant or any new Warrant issued as the result of a partial
exercise hereof and all rights and options  hereunder or thereunder shall expire
and shall be wholly null and void to the extent this Warrant or such new warrant
is not  exercised  before it expires at the close of business on the  Expiration
Date.

2. RESERVATION OF STOCK. The Company covenants and agrees that during the period
within  which the rights  represented  by this  Warrant  may be  exercised,  the
Company will at all times have authorized,  and in reserve,  a sufficient number
of shares of its Stock to provide for the exercise of the rights  represented by
this  Warrant;  provided,  however,  that in the  event  there is at any time an
insufficient  number of shares of Stock reserved and available the Company shall
as soon as practicable take such action as is required to increase the Company's
authorized  shares  of Stock in order to  provide  a  sufficient  number of such
shares.

3.   PROTECTION AGAINST DILUTION.
     ----------------------------

     3.1 Sales of Stock Below Per Share Warrant Price. In case the Company shall
     issue or grant to any person (a) rights,  warrants,  options,  exchangeable
     securities or convertible  securities (each referred to herein as "Rights")
     entitling  such person to  subscribe  for or purchase  shares of Stock at a
     price per share  less than the Per  Share  Warrant  Price or (b)  shares of
     Stock at a price per share less than the Per Share  Warrant  Price,  on the
     date fixed for the determination of persons entitled to receive such Rights
     or such shares,  the Per Share Warrant Price in effect  immediately  before
     the close of  business  on the date fixed for such  determination  shall be
     reduced by multiplying such Per Share Warrant Price by a fraction, of which
     (i) the numerator is the number of shares of Stock  outstanding  (including
     all shares of Stock issued or issuable upon  conversion of any  convertible
     security or upon the  exercise of any rights,  warrants or options) on such
     date plus the number of shares of Stock which the aggregate of the offering
     price of the total number of shares of Stock so offered for subscription or
     purchase pursuant to such Rights,  or so issued,  would purchase at the Per
     Share  Warrant  Price on such  date and (ii) the  denominator  shall be the
     number of shares of Stock outstanding (including all shares of Stock issued
     or  issuable  upon  conversion  of any  convertible  security  or upon  the
     exercise  of any  rights,  warrants or options) at the close of business on
     such date plus the number of shares of Stock so offered for subscription or
     purchase  pursuant to such Rights,  or so issued.  If, after any such date,
     any such  Rights or shares  are not in fact  issued,  or are not  exercised
     prior to the  expiration  thereof,  the Per Share  Warrant  Price  shall be
     immediately  readjusted,  effective  as of the date  such  Rights or shares
     expire,  or the date the Board of  Directors  determines  not to issue such
     Rights or shares,  to the Per Share  Warrant  Price that would have been in
     effect if the unexercised Rights had never been granted or such record date
     had not  been  fixed,  as the case may be.  Such  adjustment  shall be made
     successively  whenever any such event shall occur. For the purposes of this
     paragraph,  the aggregate of the offering  price received or to be received
     by the Company shall include the minimum  aggregate amount (if any) payable
     upon exercise or conversion of such Rights.  The value of any consideration
     received  or to be received by the  Company,  if other than cash,  is to be
     determined by the Board of Directors in good faith.

     3.2 Stock Splits and  Dividends.  If  outstanding  shares of the  Company's
     Stock shall be subdivided  into a greater number of shares or a dividend in
     Stock  shall be paid in respect of Stock,  the Per Share  Warrant  Price in
     effect  immediately prior to such subdivision or at the record date of such
     dividend shall simultaneously with the effectiveness of such subdivision or
     immediately  after the  record  date of such  dividend  be  proportionately
     reduced.  If  outstanding  shares of Stock shall be combined into a smaller
     number of shares,  the Per Share Warrant Price in effect  immediately prior
     to such combination  shall,  simultaneously  with the effectiveness of such
     combination,  be proportionately increased. When any adjustment is required
     to be made in the Per Share  Warrant  Price,  the number of shares of Stock
     purchasable  upon the  exercise  of this  Warrant  shall be  changed to the
     number  determined  by dividing (i) an amount equal to the number of shares
     issuable  upon  the  exercise  of this  Warrant  immediately  prior to such
     adjustment, multiplied by the Per Share Warrant Price in effect immediately
     prior to such  adjustment,  by (ii) the Per Share  Warrant  Price in effect
     immediately after such adjustment.

                                       3

     3.3 Reclassification, Etc. In case of any reclassification or change of the
     outstanding  securities  of the  Company  or of any  reorganization  of the
     Company (or any other  corporation  the stock or securities of which are at
     the time  receivable  upon the  exercise  of this  Warrant)  or any similar
     corporate  reorganization  on or after the date hereof that is not a Change
     of Control  (as defined  herein),  then and in each such case the holder of
     this Warrant,  upon the exercise hereof at any time after the  consummation
     of such  reclassification,  change,  reorganization,  merger or conveyance,
     shall be entitled to receive,  in lieu of the stock or other securities and
     property  receivable upon the exercise  hereof prior to such  consummation,
     the stock or other  securities  or property to which such holder would have
     been entitled  upon such  consummation  if such holder had  exercised  this
     Warrant  immediately  prior thereto,  all subject to further  adjustment as
     provided in Section 3.2; and in each such case, the terms of this Section 3
     shall be  applicable  to the shares of stock or other  securities  properly
     receivable upon the exercise of this Warrant after such consummation.

     3.4 Exempted  Issuances.  Notwithstanding  any other provision herein,  the
     foregoing  provisions  of  this  Section  3  shall  not  apply  to,  and no
     adjustment shall be made to the Per Share Warrant Price for:

          (a) shares of Stock  issuable  upon the  exercise  of options or other
          convertible  securities  previously  issued  pursuant to the Company's
          stock option, employee stock purchase or other employee benefit plan;

          (b) shares of Stock to be issued pursuant to the Company's outstanding
          stock option,  employee stock purchase or other employee  benefit plan
          that total not more than 200,000 shares of Stock per employee per year
          and an  aggregate  maximum of  2,000,000  shares of Stock per year and
          that do not contain exercise prices that are below $0.30 per share;

          (c) shares of Stock  issuable  upon  conversion  of shares of Series C
          Preferred Stock or warrants issued in connection therewith;

          (d)  shares  of  Stock  issuable  upon  conversion  of  shares  of  7%
          Convertible  Series  A  Preferred  Stock  or 5%  Convertible  Series B
          Preferred Stock of the Company or any warrants outstanding on the date
          of the filing of this Designation;

          (e) shares of Stock issuable upon conversion of Class B Common Stock;

          (f)  securities  that have been  approved for issuance or grant by the
          holders of at least a majority of the  outstanding  shares of Series C
          Preferred Stock;

                                       4
<PAGE>


          (g) securities that are issued in conjunction with an acquisition or a
          non-financing   strategic   transaction   approved  by  the  Board  of
          Directors;  provided,  however,  that the number of shares of Stock or
          securities convertible into Stock issued by the Company in conjunction
          with  non-financing  strategic  transactions  that are exempt from the
          foregoing  provisions of this Section 3 shall be limited to 10% of the
          shares of Stock  outstanding  (including all shares of Stock issued or
          issuable  upon  conversion  of any  convertible  security  or upon the
          exercise of any rights,  warrants or options) immediately prior to the
          date of such transaction; or

          (h) Shares of Stock that are issued  pursuant to that  certain  Common
          Stock and Warrant Purchase Agreement dated as of an even date herewith
          between the Company and Purchaser,  pursuant to which the Purchaser is
          purchasing this Warrant, and the related Registration Rights Agreement
          referenced therein, including, without limitation, any shares of Stock
          to be issued in connection with any penalty or anti-dilution provision
          contained in such  documents,  any shares of Common Stock issued under
          the Warrants issued as part of that offering or under the terms of the
          Common Stock and Warrant  Purchase  Agreement  relating  thereto,  and
          shares of Common Stock issued in private offerings  completed prior to
          May 31,  2007 as  provided  in Section  7.10 of the  Common  Stock and
          Warrant Purchase Agreement,  or under Warrants issued as part of those
          other  offerings,  or  under  the  terms  of the  purchase  agreements
          relating to those other offerings.

     3.5 Deferral of Small Adjustments.  Any adjustment in the Per Share Warrant
     Price otherwise  required by this Section 3 may be postponed until the date
     of the next adjustment  otherwise  required by this Section 3 to be made if
     such adjustment (together with any other adjustments  postponed pursuant to
     this paragraph (ix) and not theretofore made) would not require an increase
     or  decrease  of  more  than 1 % in  such  Per  Share  Warrant  Price.  All
     calculations  under this  Section 3 shall be made to the nearest cent or to
     the nearest I/100th of a share, as the case may be.

     3.6 Authority of Board of Directors.  The Board of Directors shall have the
     power to resolve any  ambiguity or correct any error in this Section 3, and
     its action in good faith in so doing shall be final and conclusive.

     3.7 Notice of  Adjustment.  Whenever  the  Warrant  Number or the Per Share
     Warrant  Price is adjusted  under this Section 3, the Company shall provide
     notice thereof to the holder within thirty (30) days of such adjustment.

4. MERGERS,  CONSOLIDATIONS,  SALES;  NON-IMPAIRMENT OF RIGHTS. The Company will
not,  by  amendment  of  its  Certificate  of   Incorporation   or  through  any
reorganization,  recapitalization,  transfer of assets,  consolidation,  merger,
dissolution, issuance or sale of securities or any other voluntary action, avoid
or seek to avoid the  performance of any of the terms of this Warrant,  but will
at all times in good faith take all necessary  action to carry out the intent of
all such terms.  Without  limiting the generality of the foregoing,  the Company
(a) will not cause the par value of any  securities  receivable  on  exercise of
this Warrant to be in excess of the amount  payable  therefor on such  exercise,
and (b) will take all  action as may be  necessary  or  appropriate  so that the
Company may validly and legally  issue fully paid and  nonassessable  shares (or
other  securities or property  deliverable  hereunder) upon the exercise of this
Warrant.  In  the  event  the  Company  sells  or  otherwise  transfers  all  or
substantially  all of its assets to another  corporation  or other  entity  and,
following the sale or transfer,  a majority of the combined  voting power of the
then-outstanding securities of the other corporation or entity immediately after
the sale or transfer is held in the aggregate by the holders of Voting Stock (as
defined below)  immediately prior to the sale or transfer,  then, as a condition
of such sale or transfer,  lawful and adequate  provision  shall be made whereby
the holder of this Warrant shall  thereafter  have the right to receive upon the
basis and upon the  terms and  conditions  specified  herein  and in lieu of the
shares of Stock immediately  theretofore  purchasable hereunder,  such shares of
stock,  securities  or assets as may (by virtue of such  consolidation,  merger,
sale,  reorganization or  reclassification) be issued or payable with respect to
or in exchange for a number of  outstanding  shares of Stock equal to the number
of shares of Stock  immediately  theretofore so  purchasable  hereunder had such
sale or transfer not taken  place,  and in any such case  appropriate  provision
shall be made with  respect to the rights  and  interests  of the holder of this
Warrant to the end that the provisions hereof  (including,  without  limitation,
provisions for adjustment of the Warrant Number and the Per Share Warrant Price)
shall thereafter be applicable as nearly as may be, in relation to any shares of
stock,  securities  or  assets  thereafter  deliverable  upon  exercise  of this
Warrant.  The Company shall not effect any such sale or transfer unless prior to
or  simultaneously  with the consummation  thereof,  the entity  purchasing such
assets shall assume by written instrument, reasonably satisfactory to the holder
of this Warrant, executed and mailed or delivered to the holder of this Warrant,
the  obligation  to deliver to such holder such shares of stock,  securities  or
assets as, in  accordance  with the  foregoing  provisions,  such  holder may be
entitled to receive.

                                       5
<PAGE>


5. DISSOLUTION OR LIQUIDATION.  In the event of any proposed distribution of the
assets of the Company in dissolution or liquidation  (except under circumstances
when the foregoing  Section 4 shall be applicable) the Company shall mail notice
thereof  to the  holder  of this  Warrant  and  shall  make no  distribution  to
shareholders  until the  expiration  of 30 days from the date of  mailing of the
aforesaid  notice and, in any such case, the holder of this Warrant may exercise
this Warrant within 30 days from the date of the mailing of such notice, and all
rights  herein  granted  not  so  exercised  within  such  30 day  period  shall
thereafter become null and void.

6.   CHANGE OF CONTROL; FUNDAMENTAL TRANSACTIONS.
     --------------------------------------------

     (a)  Change of  Control.  In the event of a Change of  Control,  as defined
below, the Company shall provide notice thereof to the holder of this Warrant at
least ten (10) days prior to the contemplated closing date or occurrence of such
Change of  Control  (the  "Contemplated  Closing  Date").  Upon the  Purchaser's
receipt of the Company's  notice of a Change of Control,  the Purchaser  may, at
its option, elect to exercise this Warrant pursuant to Section 1 hereof.  Should
the  Purchaser  decline or fail to exercise  this  Warrant  before 5:00 p.m. New
York, New York time on the  Contemplated  Closing Date,  then this Warrant shall
immediately prior to the closing of the Change of Control be deemed to have been
exercised by cashless exercise, as provided for in Section 1 hereof, without any
further  action  on the  part of the  Purchaser,  and  all  rights  and  options
hereunder  shall  expire  and  shall be wholly  null and void.  In the case of a
cashless  exercise  pursuant to this  Section,  from and after the  Contemplated
Closing  Date,  the  Purchaser  shall be  deemed  the  holder  of  record of the
securities  issuable  upon  exercise of this  Warrant,  and this  Warrant  shall
represent  only the right to receive,  upon return of the Warrant to the Company
for  cancellation,  a certificate  representing  the securities  issuable to the
Purchaser upon exercise of this Warrant.

                                       6
<PAGE>


For purposes of this Warrant,  a "Change of Control" shall be deemed to occur if
(A) any of the following occur:

     (i) The Company is merged, consolidated or reorganized into or with another
     corporation or other entity,  and as a result of the merger,  consolidation
     or reorganization  less than a majority of the combined voting power of the
     then-outstanding  securities of the corporation or entity immediately after
     the  transaction  is held in the  aggregate  by the holders of Voting Stock
     immediately prior to the transaction;

     (ii) The Company sells or otherwise  transfers all or substantially  all of
     its assets to another  corporation  or other entity and, as a result of the
     sale or transfer,  less than a majority of the combined voting power of the
     then-outstanding  securities of the other corporation or entity immediately
     after the sale or  transfer  is held in the  aggregate  by the  holders  of
     Voting Stock immediately prior to the sale or transfer; or

     (iii)  Any  person or group of  persons  (within  the  meaning  of  Section
     13(d)(3) of the Securities Exchange Act of 1934) that holds less than 5% of
     the  Voting  Stock of the  Company  outstanding  on the  date of the  first
     issuance of any of the Warrants  becomes the beneficial owner of a majority
     of the Voting Stock.;

     and (B) the per share price for any such transaction mentioned in (A) above
     is at least $1.35 per share of Stock.

For purposes of this Warrant, the term "Voting Stock" means the capital stock of
the Company of any class or series entitled to vote generally in the election of
directors.

     (b) Fundamental Transactions.  The Company shall not enter into or be party
to a  Fundamental  Transaction  that is not a Change of  Control  unless (i) the
Successor  Entity assumes in writing all of the obligations of the Company under
this  Warrant  and the  other  Transaction  Documents  in  accordance  with  the
provisions  of this  Section  6  pursuant  to  written  agreements  in form  and
substance  satisfactory  to the  Required  Holders and  approved by the Required
Holders prior to such Fundamental  Transaction,  including agreements to deliver
to each  holder of  Warrants  in  exchange  for such  Warrants a security of the
Successor Entity evidenced by a written instrument substantially similar in form
and  substance  to this  Warrant,  including,  without  limitation,  an adjusted
exercise  price equal to the value for the shares of Common  Stock  reflected by
the terms of such Fundamental  Transaction,  and exercisable for a corresponding
number of shares of  capital  stock  equivalent  to the  shares of Common  Stock
acquirable and receivable  upon exercise of this Warrant  (without regard to any
limitations  on  the  exercise  of  this  Warrant)  prior  to  such  Fundamental
Transaction,  and satisfactory to the Required  Holders.  Upon the occurrence of
any  Fundamental  Transaction,  the  Successor  Entity shall  succeed to, and be
substituted  for  (so  that  from  and  after  the  date  of  such   Fundamental
Transaction,  the  provisions of this Warrant  referring to the "Company"  shall
refer instead to the Successor  Entity),  and may exercise every right and power
of the Company and shall assume all of the obligations of the Company under this
Warrant with the same effect as if such  Successor  Entity had been named as the
Company herein. Upon consummation of the Fundamental Transaction,  the Successor
Entity shall deliver to the Holder  confirmation that there shall be issued upon
exercise of this Warrant at any time after the  consummation  of the Fundamental
Transaction,  in lieu of the  shares of the Common  Stock (or other  securities,
cash, assets or other property)  issuable upon the exercise of the Warrant prior
to such Fundamental Transaction,  such shares of stock, securities, cash, assets
or any other  property  whatsoever  (including  warrants  or other  purchase  or
subscription  rights)  which the Holder would have been entitled to receive upon
the happening of such  Fundamental  Transaction  had this Warrant been converted
immediately  prior to such  Fundamental  Transaction,  as adjusted in accordance
with the provisions of this Warrant.  In addition to and not in substitution for
any  other  rights  hereunder,  prior  to the  consummation  of any  Fundamental
Transaction  pursuant to which holders of shares of Common Stock are entitled to
receive  securities or other assets with respect to or in exchange for shares of
Common Stock (a "Corporate Event"), the Company shall make appropriate provision
to insure  that the Holder  will  thereafter  have the right to receive  upon an
exercise of this Warrant at any time after the  consummation  of the Fundamental
Transaction  but  prior to the  Expiration  Date,  in lieu of the  shares of the
Common Stock (or other securities, cash, assets or other property) issuable upon
the exercise of this Warrant prior to such Fundamental Transaction,  such shares
of stock,  securities,  cash, assets or any other property whatsoever (including
warrants or other purchase or  subscription  rights) which the Holder would have
been entitled to receive upon the happening of such Fundamental  Transaction had
this Warrant been exercised  immediately prior to such Fundamental  Transaction.
Provision  made  pursuant  to the  preceding  sentence  shall  be in a form  and
substance  reasonably  satisfactory to the Required  Holders.  The provisions of
this  Section  shall  apply  similarly  and  equally to  successive  Fundamental

     declared  effective by the  Securities and Exchange  Commission  (SEC) and,
     thereafter,  the  holder  purports  to  assigns  all  or a  portion  of the
     Underlying Stock to any other person,  the assignee shall have the right to
     cause the  Registration  Statement to be amended or the prospectus  related
     thereto to be supplemented (at the expense of the Company),  in either case
     to name such assignee as a selling stockholder,  provided that the use of a
     post-effective  amendment or a supplement to the prospectus is permitted by
     applicable law for such purpose.

     registered  for  resale,   bear  on  the  face  thereof  a  legend  reading
     substantially as follows:

     BEEN  REGISTERED OR QUALIFIED FOR SALE UNDER THE SECURITIES ACT OF 1933, AS
     AMENDED (THE  "ACT"),  OR ANY STATE  SECURITIES  LAW AND MAY NOT BE SOLD OR
     TRANSFERRED  IN THE  ABSENCE OF SUCH  REGISTRATION,  UNLESS THE  COMPANY IS
     REASONABLY SATISFIED THAT THE PROPOSED SALE OR TRANSFER IS EXEMPT FROM SUCH
     REGISTRATION REQUIREMENTS.

     10.4  Removal of Legend.  In the event that the  Company  shall  receive an
     opinion  of  its  counsel  or  counsel  of the  holder,  which  opinion  is
     reasonably  acceptable to it, that,  in the opinion of such  counsel,  such
     legend is not, or is no longer,  necessary or required (including,  without
     limitation,  because of the availability of the exemption  afforded by Rule
     144 of the General Rules and  Regulations  of the  Securities  and Exchange
     Commission),  the Company shall,  or shall instruct its transfer agents and
     registrars  to,  remove such legend from the  certificates  evidencing  the
     Restricted  Stock or issue new  certificates  without  such  legend in lieu
     thereof.  The Company shall also remove the legend if the Underlying  Stock
     has been registered for resale with the SEC.
