Exhibit 4.6
-----------

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,
OR ANY STATE SECURITIES LAW AND MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
SUCH REGISTRATION, UNLESS THE HOLDER HEREOF PROVIDES THE COMPANY WITH AN OPINION
OF COUNSEL SATISFACTORY TO THE COMPANY THAT THE PROPOSED SALE OR TRANSFER IS
EXEMPT FROM SUCH REGISTRATION REQUIREMENTS.

                               WARRANT TO PURCHASE
                                    SHARES OF
                              CLASS A COMMON STOCK

                          Void after September 14, 2010

     THIS IS TO CERTIFY that, as of this 14th day of September,  2005, for value
received and subject to the provisions  hereinafter set forth,  Bathgate Capital
Partners LLC (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  September  14,  2010  (the  "Expiration  Date"),  at a  price
initially  equal  to   Thirty-Seven   Cents  ($0.37)  per  share  (the  "Warrant
Calculation  Price"), Two Hundred Seventy Thousand Two Hundred Seventy (270,270)
(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 not subject to
adjustment and 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 the  surrender  of this  Warrant  (with the
subscription  form at the end hereof 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 or by certified or official bank check, or by cashless  exercise as
hereinafter  set forth.  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

<PAGE>

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.

     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.

     3.     Protection  Against  Dilution.  The  Warrant Number  is  subject  to
adjustment from time to time upon the occurrence of the events enumerated in, or
as otherwise provided in, this Section 3.

            3.1     Adjustment for Change in Capital Stock. If the Company:

            (1) pays a dividend or makes a  distribution  on its Stock in shares
of its Stock;

            (2) subdivides or reclassifies its outstanding  shares of Stock into
a greater number of shares;

            (3) combines or reclassifies its outstanding  shares of Stock into a
smaller number of shares;

            (4) makes a  distribution  on its Stock in shares of  capital  stock
other than Stock; or

            (5)  issues  by  reclassification  of its  Stock  any  shares of its
capital stock;

     then the Warrant Number in effect immediately prior to such action shall be
     proportionately  adjusted  so that the holder  may  receive  the  aggregate
     number and kind of shares of capital  stock of the Company or other capital
     stock which such holder would have owned immediately  following such action
     if such Warrant had been exercised immediately prior to such action. If, as
     a result of any  adjustment  pursuant to this Section 3.1, the holder shall
     become  entitled  to  receive  shares of two or more  classes  or series of
     securities  of the  Company or  otherwise,  the Board of  Directors  of the
     Company shall  equitably  determine the allocation of the adjusted  Warrant
     Price between or among shares of the holder of such allocation.

     The adjustment shall become effective  immediately after the record date in
the case of a dividend or distribution and immediately  after the effective date
in the case of a subdivision, combination or reclassification.

     Such adjustment shall be made successively  whenever any event listed above
shall occur.

<PAGE>

            3.2     Notice of Adjustment. Whenever the Warrant Number or Warrant
Calculation  Price is adjusted  under this  section,  the Company  shall provide
notice thereof to the holder within thirty (30) days of such adjustment.

            3.3     Additional  Adjustments.  In  the   event  of  any  and  all
adjustments  to the Warrant  Number in  accordance  with this Section 3, the per
share Warrant Price shall be adjusted so that it is equal to the quotient of (a)
the aggregate Warrant Price and (b) the Warrant Number as adjusted.

     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 Common  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 Common  Stock
equal to the  number  of  shares  of Common  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.    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.

<PAGE>

     6.     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.

     For  purposes of this  Warrant,  a "Change of  Control"  shall be deemed to
occur if 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.

     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.

     7.     Fractional Shares. Fractional shares  shall not be  issued  upon the
exercise of this Warrant but in any case where the holder hereof  would,  except
for the  provisions  of this  paragraph,  be entitled  under the terms hereof to
receive a  fractional  share upon the  complete  exercise of this  Warrant,  the
Company shall, upon the exercise of this Warrant for the largest number of whole
shares then called for, pay a sum in cash equal to the excess of the Fair Market
Value of such  fractional  share  over the  proportional  part of the per  share
Warrant Price represented by such fractional share.

     8.     Fully Paid Stock; Taxes. The Company  covenants  and agrees that the
shares of stock  represented by each and every  certificate  for its Stock to be
delivered on any exercise of this Warrant  shall,  at the time of such delivery,
be duly  authorized,  validly  issued  and  outstanding  and be  fully  paid and
nonassessable.  The Company  further  covenants and agrees that it will pay when

<PAGE>

due and payable any and all federal and state taxes, other than taxes on income,
which may be payable in  respect  of this  Warrant or any Stock or  certificates
therefor  upon the  exercise of the rights  herein  provided for pursuant to the
provisions  hereof.  The Company shall not, however,  be required to pay any tax
which may be payable in respect of any  transfer  involved in the  transfer  and
delivery of stock  certificates in the name other than that of the holder of the
Warrant converted,  and any such tax shall be paid by such holder at the time of
presentation.

     9. Closing of Transfer Books.  The holder of this Warrant shall continue to
have the right to  exercise  this  Warrant  even  during a period when the stock
transfer books of the Company for its Stock are closed. The Company shall not be
required, however, to deliver certificates of its Stock upon such exercise while
such books are duly closed for any  purpose,  but the Company may  postpone  the
delivery of the certificates for such Stock until the opening of such books, and
they shall, in such case, be delivered forthwith upon the opening thereof, or as
soon as practicable thereafter.

     10. Restrictions on Transferability of Warrants and Shares; Compliance with
Securities Act;  Exchange,  Assignment or Loss of Warrant.  This Warrant and the
Stock issued upon the exercise  hereof,  and any security  into which such Stock
may be convertible  ("Underlying  Stock") shall not be transferable  except upon
the conditions  hereinafter  specified,  which conditions are intended to insure
compliance with the provisions of the Securities Act of 1933, as amended, or any
similar Federal statute at the time in effect (the "Securities  Act") in respect
of the transfer of any Warrant or any such Stock or any security into which such
Stock may be convertible.

             10.1     Assignments  Generally.   Except  as  may   otherwise   be
expressly provided herein, this Warrant is exchangeable, without expense, at the
option of the  holder,  upon  compliance  with the  express  provisions  of this
Section 10 and  presentation  and  surrender of the Warrant to the Company,  for
other  Warrants  of  different  denominations  entitling  the holder  thereof to
purchase  in the  aggregate  the same  number  of  shares  of Stock  purchasable
hereunder.  Any  assignment  shall be made by  surrender  of this Warrant to the
Company  with the Form of  Assignment  annexed  hereto duly  executed  and funds
sufficient to pay any transfer tax. Upon compliance with the express  provisions
of this Section 10, the Company shall,  without charge, cause to be executed and
delivered a new Warrant in the name of the assignee named in such  instrument of
assignment  and this Warrant  shall  promptly be  canceled.  This Warrant may be
divided  or  combined  with  other  warrants  that  carry the same  rights  upon
presentation hereof to the Company together with a written notice specifying the
names and denominations in which new Warrants are to be issued and signed by the
holder hereof.

             10.2     Notice of Proposed  Transfer; Opinion. The  holder of each
Warrant  or any  Underlying  Stock  that is not the  subject  of a  registration
statement effective under the Securities Act ("Restricted Stock"), by acceptance
thereof,  agrees to give prior  written  notice to the Company of such  holder's
intention  to transfer  such  Warrant or the  Restricted  Stock (as  hereinafter
defined)  relating  thereto or such Restricted  Stock (or any portion  thereof),
describing  briefly  the  manner and  circumstances  of the  proposed  transfer,
including the identity of the proposed  transferee and the  consideration  to be
paid thereby.  Promptly after receiving such written  notice,  the Company shall
present  copies thereof to Company  counsel and, if required by the Company,  to
counsel  designated  by such holder.  If in the opinion of each such counsel the
proposed  transfer may be effected without  registration or qualification  under
any  Federal  or State  law of such  Warrant  or the  Underlying  Shares or such
Restricted  Stock,  the Company,  as promptly as practicable,  shall notify such
holder of such opinion and of the terms and conditions,  if any, to be observed,
whereupon  such  holder  shall be  entitled  to  transfer  such  Warrant or such
Restricted  Stock,  all in accordance with the terms of the notice  delivered to
such holder by the Company.

<PAGE>

             If in the opinion of either of such counsel  (such opinion to state
the  basis of the legal  conclusions  reached  therein)  the  proposed  transfer
described in the written notice given pursuant to this  subparagraph  may not be
effected without such  registration or qualification or without  compliance with
the conditions of an exemptive  regulation of the Commission,  the Company shall
promptly  notify such holder and thereafter such holder shall not be entitled to
effect  such  transfer  until  receipt of a  subsequent  notice from the Company
pursuant to the  immediately  preceding  sentence or until such  registration or
qualification  or filing  has become  effective.  All fees and  expenses  of the
Company's counsel shall be borne by the Company and the fees of the counsel,  if
any, designated by any holder of this Warrant or Restricted Stock shall be borne
by such holder.

             Notwithstanding  anything  to the  contrary  set forth  herein,  no
opinion of counsel  shall be required in the case of transfers to  affiliates of
the holder of this Warrant or of the Underlying Stock.

             10.3    Certain Assignments Following Registration. Notwithstanding
anything to the contrary  contained  herein,  if the Company has  registered the
Underlying  Stock pursuant to a Registration  Statement  which has been 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,  in either case
to name such assignee as a selling  stockholder,  provided that (i) the use of a
post-effective  amendment  or a  supplement  to the  prospectus  is permitted by
applicable law for such purpose, and (ii) all costs and expenses to the Company,
including without limitation legal and accounting expenses, incurred to so amend
such  Registration  Statement or supplement the Prospectus  shall be paid by the
assignee  requesting such amendment (or shared on a pro rata basis to the extent
more than one assignee requests such amendment).

             10.4     Restrictive Legends. Each  Warrant shall  bear on the face
thereof a legend  substantially  in the form of the notice endorsed on the first
page of this Warrant.

             Each  certificate for shares of Underlying  Stock initially  issued
upon the exercise of any Warrant and each  certificate  for shares of Underlying
Stock  issued to a  subsequent  transferee  of such  certificate  shall,  unless
otherwise  permitted  by the  provisions  of this  Section  10, bear on the face
thereof a legend reading substantially as follows:

     THE TRANSFER, SALE, ASSIGNMENT, PLEDGE AND ENCUMBRANCE OF OTHER DISPOSITION
     OF THE SHARES OF CLASS A COMMON STOCK  REPRESENTED BY THIS  CERTIFICATE ARE
     SUBJECT TO CERTAIN  RESTRICTIONS SET FORTH IN THE WARRANT UNDER WHICH THESE
     SHARES  WERE  ISSUED  AND WHICH  TERMS  CONTINUE  IN EFFECT  FOLLOWING  THE
     EXERCISE  THEREOF.  A COPY OF THE  WARRANT  IS ON FILE IN THE OFFICE OF THE
     SECRETARY  OF THE  COMPANY.  NO  SALE  OR  OTHER  TRANSFER  OF  THE  SHARES
     REPRESENTED  BY THIS  CERTIFICATE  MAY BE EFFECTED  EXCEPT  PURSUANT TO THE
     TERMS OF THE WARRANT.

             10.5     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

<PAGE>

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.

     11. Partial Exercise and Partial  Assignment.  If this Warrant be exercised
in part only,  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 as provided in paragraph 1 hereof.  If this Warrant is partially
assigned,  this Warrant  shall be  surrendered  at the  principal  office of the
Company (with the partial assignment form at the end hereof duly executed),  and
thereupon a new Warrant shall be issued to the holder hereof covering the number
of shares not assigned and setting  forth the  proportionate  aggregate  Warrant
Price  applicable  to such shares not  assigned.  The  assignee of such  partial
assignment  of this  Warrant  shall also be  entitled  to receive a new  Warrant
covering  the number of shares so assigned and setting  forth the  proportionate
aggregate Warrant Price applicable to such assigned shares.

     12. Registration Rights

             12.1     Definitions.  As  used  in  this Section 12, the following
terms shall have the meanings set forth below:

             (a) The terms  "register,"  "registered" and  "registration"  shall
refer  to a  registration  effected  by  preparing  and  filing  a  registration
statement or similar document in compliance with the Act, and the declaration or
ordering of the effectiveness of such registration statement or document.

             (b) The term  "Registrable  Securities"  shall mean together in the
aggregate:  (A) the  Underlying  Stock issued or issuable  upon exercise of this
Warrant  and (B) the Stock held by or issuable  upon  exercise of any warrant or
conversion   of   convertible   security  to  any  other  persons  with  similar
registration rights as provided in this Warrant.

             (c) The term "Holder" means any person owning of record Registrable
Securities.

             12.2     Piggy-back   Registration   Rights. If  (but  without  any
obligation  to do so) at any time  prior to the  date  one (1)  year  after  the
Purchaser has fully exercised this Warrant, the Company proposes to register any
of its securities  under the Act in connection  with the public offering of such
securities  solely for cash (other than a registration  on Form S-4, Form S-8 or
any form which does not include  substantially  the same information as would be
required to be included in a  registration  statement  covering  the sale of the
Registrable  Securities and a registration statement relating to a PIPE (private
investment public equity) or similar transaction),  the Company shall, each such
time,  promptly give the Holder  written notice of such  registration.  Upon the
written  request of the Holder  given within  twenty (20) days after  receipt of
such  written  notice  from the  Company,  the  Company  shall,  subject  to the
provisions  of  Section  10,  cause to be  registered  under  the Act all of the
Registrable Securities that the Holder has requested to be registered; provided,
however,  that if the managing  underwriter of any underwritten  offering by the
Company expresses reasonable written objection to the registration of all of the
Registrable   Securities,   then  the  Registrable  Securities  which  shall  be
registered in such offering on behalf of holders of Registrable Securities shall
be reduced in the  proportion  equal to the average  proportion  of reduction as
that of all such holders seeking  registration in connection with such offering,
subject to any rights granted to other holders of securities of the Company that
are expressly by the terms of their agreements with the Company entitled to have
priority registration rights. The inclusion of any of the Purchaser's

<PAGE>

Registrable  Securities  in a  registration  statement  filed by the Company and
declared  effective  by the SEC  shall  be  deemed  to be the  exercise  by such
Purchaser of the piggy-back registration rights granted herein to such Purchaser
except as to such  Registrable  Securities as were not registered as a result of
the immediately preceding sentence.

             12.3     Obligations of the Company.  Whenever  required  hereunder
to effect the registration of any Registrable Securities,  the Company shall, as
expeditiously as reasonably possible:

             (a) Prepare  and file with the SEC a  registration  statement  with
respect  to  such  Registrable  Securities  and act  diligently  to  cause  such
registration  statement  to become  effective  as  promptly as  practicable  and
maintain the effectiveness of the registration statement (i) in the case of firm
commitment  underwritten  public offering,  until each underwriter has completed
the distribution of all of the securities  purchased by it, and (ii) in the case
of any other offering, 180 days after the effective date thereof, except that in
the case of  registrations  on Form S-3 or its  equivalent,  those  registration
statements  shall in any  event be kept  effective  until at least  one (1) year
after the Purchaser has fully exercised this Warrant.

             (b) Prepare and file with the SEC such  amendments and  supplements
to such  registration  statement and the prospectus used in connection with such
registration  statement as may be necessary to comply with the provisions of the
Act  with  respect  to  the  disposition  of  all  securities  covered  by  such
registration statement.

             (c)  Furnish  to  the  Purchasers  such  numbers  of  copies  of  a
prospectus,   including  a  preliminary  prospectus,   in  conformity  with  the
requirements of the Act, and such other documents as they may reasonably request
in order to facilitate the disposition of Registrable Securities owned by them.

             (d) Use its best  efforts to register  and  qualify the  securities
covered  by  such  registration  statement  under  the  securities  laws of such
jurisdictions  as  shall  be  reasonably  requested  by the  Purchasers  for the
distribution of the securities covered by the registration  statement,  provided
that the Company shall not be required in connection therewith or as a condition
thereto  to qualify to do  business  or to file a general  consent to service of
process in any such jurisdiction.

             (e) In the event of any underwritten  public  offering,  enter into
and perform its obligations under an underwriting agreement with terms generally
satisfactory to the managing underwriter of such offering.

             (f) Notify the  Purchasers,  promptly  after the Company shall have
received notice thereof,  of the time when the  registration  statement  becomes
effective or any supplement to any prospectus forming a part of the registration
statement has been filed.

             (g)  Notify  the  Purchasers  of  any  stop  order  suspending  the
effectiveness of the registration  statement and use its reasonable best efforts
to remove such stop order.

             12.4      Furnish Information. It shall be a condition precedent to
the  obligations  of the  Company to take any action  pursuant  hereto  that the
Purchaser,  having  chosen  to have  its  Registrable  Securities  included  for
registration,  shall  furnish to the  Company  such  information  regarding  the
Purchaser,  its Registrable Securities and the intended method of disposition of
such securities as shall be required to effect the registration thereof. The

<PAGE>

Purchaser  shall  be  required  to  represent  to  the  Company  that  all  such
information that is given is complete and accurate in all material respects. The
Purchaser  shall  deliver  to the  Company  a  statement  in  writing  from  the
beneficial  owners of such  securities  that such  beneficial  owners  bona fide
intend to sell, transfer or otherwise dispose of such securities.

             12.5      Expenses.

             (a) Registration  Expenses. All expenses incurred by the Company in
complying  with the terms of Sections  12.2 and 12.3 hereof,  including  without
limitation,  all  registration  and filing  fees,  printing  expenses,  fees and
disbursements of counsel for the Company,  "Blue Sky" fees and expenses, and the
expense of any special audits  incident to or required by any such  registration
(but excluding the compensation of regular  employees of the Company which shall
be paid in any event by the Company) shall be borne by the Company.

             (b) Selling  Expenses.  All underwriting  discounts,  underwriters'
expense allowance, and selling commissions applicable to the sale of Registrable
Securities  by the  Purchasers  and all fees and  disbursements  of any  special
counsel  (other  than  the  Company's  regular  counsel)  shall  be borne by the
Purchasers of the Registrable  Securities so registered pro rata on the basis of
the number of Registrable Securities so registered.

             12.6     Underwriting   Requirements;   Lock-up   Provisions.   All
Purchasers  proposing to  distribute  their  Registrable  Securities  through an
underwriting  in which the Company has proposed or is proposing to  participate,
shall  (together with the Company and any other  Purchasers  distributing  their
securities  through such underwriting)  enter into an underwriting  agreement in
customary form with the underwriter or underwriters selected for underwriting by
the Company. If any Purchaser disapproves of the terms of any such underwriting,
such Purchaser may elect to withdraw  therefrom by written notice to the Company
and the managing underwriter; such notice to be given by the Purchaser not later
than two (2) business  days  following  receipt of the  Company's  notice (which
shall include the terms of the  underwriting  agreement)  to Purchaser  that the
Company  will file a  registration  statement  (not later than five (5) business
days after such  Company's  notice) which will include a preliminary  prospectus
which sets forth the number of shares of Common  Stock to be offered for sale by
selling stockholders. Any Registrable Securities excluded or withdrawn from such
underwriting  shall  not be  withdrawn  from  such  registration  except  at the
election of the Purchaser.

     Notwithstanding  the  foregoing,  the  Purchaser  acknowledges  that if the
Company  elects to  distribute  its shares in an  underwritten  public  offering
(whether or not any  Registrable  Securities held by Purchaser are included as a
part of such  offering),  the  underwriter  may  require as a  condition  of the
offering that the Purchaser agree to a lock-up of the Registrable Securities for
a  period  commencing  10 days  prior  to the  anticipated  commencement  of the
offering and continuing for up to 180 days after completion of the offering (the
"Lock-up  Provision").  The  Purchaser  agrees  that,  if  requested by any such
underwriter and not waived by the Company,  such Purchaser will be bound by such
Lock-up Provisions if required by such underwriter.

             12.7     Indemnification.   In   the event   that  any  Registrable
Securities are included in a registration statement pursuant hereto:

             (a) To the extent  permitted by law, the Company will indemnify and
hold  harmless  each  Purchaser,  the officers,  directors,  employees,  agents,
attorneys and partners of each  Purchaser,  any  underwriter  (as defined in the
Act) for such Purchaser and each person,  if any, who controls such Purchaser or

<PAGE>

underwriter  within the  meaning of the Act or the  Exchange  Act,  against  any
losses,  claims,  damages or  liabilities  (joint or  several) to which they may
become  subject  under the Act, the Exchange Act or other  federal or state law,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof)  arise  out of or are  based  upon  any  of the  following  statements,
omissions or violations (collectively,  a "Violation"): (A) any untrue statement
or alleged untrue  statement of a material fact  contained in such  registration
statement,  including any preliminary  prospectus or final prospectus  contained
therein or any  amendments or supplements  thereto;  (B) the omission or alleged
omission to state  therein a material  fact  required to be stated  therein,  or
necessary to make the statements therein not misleading; or (C) any violation or
alleged  violation by the Company of the Act, the Exchange  Act, any  applicable
state  securities law or any rule or regulation  promulgated  under the Act, the
Exchange  Act or any  applicable  state  securities  law;  and the Company  will
reimburse the Purchaser for any legal or other expenses  reasonably  incurred by
them in connection with investigating or defending any such loss, claim, damage,
liability or action;  provided,  however, that the indemnity agreement contained
in this Subsection  10.9(a) shall not apply to amounts paid in settlement of any
such loss,  claim,  damage,  liability or action if such  settlement is effected
without the  consent of the Company  (which  consent  shall not be  unreasonably
withheld),  nor shall the  Company be liable in any such case for any such loss,
claim,  damage,  liability  or action to the extent  that it arises out of or is
based upon a Violation  which  occurs in reliance  upon and in  conformity  with
written  information  furnished  expressly  for  use  in  connection  with  such
registration by any such Purchaser, underwriter or controlling person; provided,
however, that the Company will not be liable in any such case to the extent that
any such  loss,  claim,  damage or  liability  arises out of or is based upon an
untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in said registration  statement,  said preliminary  prospectus,  said final
prospectus  or said  amendment or  supplement in reliance upon and in conformity
with written information furnished by such Purchaser or any other Purchaser, for
use  in the  preparation  thereof;  and  further  provided,  however,  that  the
foregoing  indemnity  agreement is subject to the condition that,  insofar as it
relates to any untrue statement,  alleged untrue statement,  omission or alleged
omission made in any  preliminary  prospectus  but eliminated or remedied in the
prospectus,  such  indemnity  agreement  shall not inure to the  benefit  of any
underwriter or broker,  if a copy of the final  prospectus was not sent or given
to such person with or prior to the  confirmation of the sale of such securities
to such person.

             (b) To the extent  permitted by law,  each selling  Purchaser  will
indemnify  and hold  harmless the Company,  its  directors,  its  officers,  its
employees, its agents, its attorneys, any person who controls the Company within
the meaning of the Act or the Exchange Act, any underwriter  (within the meaning
of the Act) for the Company and any person who controls such underwriter against
any  losses,  claims,  damages or  liabilities  joint or  several)  to which the
Company or any such director,  officer,  employee, agent, attorney,  controlling
person, or underwriter or controlling person may become subject,  under the Act,
the Exchange Act or other federal or state law, insofar as such losses,  claims,
damages or liabilities (or actions in respect thereto) arise out of or are based
upon any  Violation,  in each case to the extent (and only to the  extent)  that
such  Violation   occurs  in  reliance  upon  and  in  conformity  with  written
information furnished by the Purchaser expressly for use in connection with such
registration;  and the  Purchaser  will  reimburse  any legal or other  expenses
reasonably  incurred by the Company or any such director,  officer,  controlling
person,   underwriter  or  controlling   person  thereof,   in  connection  with
investigating or defending any such loss,  claim,  damage,  liability or action;
provided,  however,  that the indemnity  agreement  contained in this Subsection
10.9(b) shall not apply to amounts paid in  settlement of any such loss,  claim,
damage,  liability or action if such settlement is effected  without the consent
of the Purchaser,  which consent shall not be unreasonably withheld, and further

<PAGE>

provided that Purchaser's obligations under this subsection shall not exceed the
amount  invested  by  Purchaser  in the  securities  that  are  included  in the
registration to which the violation relates.

             (c)  Promptly  after  receipt by an  indemnified  party  under this
Section  10.9  of  notice  of the  commencement  of any  action  (including  any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 10.9, notify the
indemnifying party in writing of the commencement  thereof, and the indemnifying
party  shall  have  the  right  to  participate  in,  and,  to  the  extent  the
indemnifying  party so  desires,  jointly  with  any  other  indemnifying  party
similarly  notified,  to  assume  the  defense  thereof  with  counsel  mutually
satisfactory to the parties; provided,  however, that an indemnified party shall
have the right to retain its own counsel,  with the fees and expenses to be paid
by the indemnifying  party, if  representation  of such indemnified party by the
counsel retained by the indemnifying  party would be inappropriate due to actual
or potential  differing  interests  between such indemnified party and any other
party  represented by such counsel in such proceeding.  The failure to notify an
indemnifying  party within a  reasonable  time of the  commencement  of any such
action,  to the extent  prejudicial to its ability to defend such action,  shall
relieve such indemnifying  party of any liability to the indemnified party under
this Section 10.9, but the omission so to notify the indemnifying party will not
relieve it of any liability that it may have to any indemnified  party otherwise
than under this Section.

             12.8     Reports Under Exchange Act.  Following registration of the
Company's  securities under the Exchange Act and with a view of making available
to the  Purchasers  the benefits of Rule 144  promulgated  under the Act and any
other rule or  regulation  of the SEC that may at any time permit a Purchaser to
sell securities of the Company to the public without  registration,  the Company
agrees to:

             (a) use its  best  efforts  to make  and  keep  public  information
available,  as those terms are understood and defined in Rule 144, at all times;
and

             (b) use its best  efforts  to file with the SEC in a timely  manner
all reports and other  documents  required of the Company  under the Act and the
Exchange Act.

             12.9     Purchaser's Acceptance of Obligations.  Acceptance of this
Warrant  by its  Purchaser(s)  shall be deemed  to  constitute  the  unqualified
acceptance by the Purchaser of all of the terms and conditions set forth herein.

     13.     Lost, Stolen Warrants, etc. In case any Warrant shall be mutilated,
stolen or destroyed, the Company may issue a new Warrant of like date, tenor and
denomination  and  deliver the same in exchange  and  substitution  for and upon
surrender and cancellation of any mutilated  Warrant,  or in lieu of any Warrant
lost, stolen or destroyed,  upon receipt of evidence satisfactory to the Company
of the loss, theft or destruction of such Warrant, and upon receipt of indemnity
satisfactory to the Company.

     14.     Warrant Holder  Not Shareholder.  This Warrant does not confer upon
the holder  hereof  any right to vote or to  consent  or to receive  notice as a
shareholder of the Company,  as such, in respect of any matters  whatsoever,  or
any other rights or liabilities as a shareholder,  prior to the exercise  hereof
as hereinbefore provided.

     15.     Severability. Should  any part of this Warrant  for any  reason  be
declared  invalid,  such decision shall not affect the validity of any remaining
portion,  which  remaining  portion  shall remain in force and effect as if this

<PAGE>

Warrant had been executed with the invalid portion thereof eliminated, and it is
hereby  declared  the  intention  of the  parties  hereto  that they  would have
executed and accepted the remaining  portion of this Warrant  without  including
therein any such part, parts or portion which may, for any reason,  be hereafter
declared invalid.

     18.  OBLIGATIONS  OF  THE  COMPANY.  In   connection  with   the  Company's
obligation  under Section 3 hereof to file the  Registration  Statement with the
SEC and to use its best  efforts to cause the  Registration  Statement to become
effective  as soon as  practicable,  the  Company  shall,  as  expeditiously  as
reasonably possible:

          (a) Prepare and file with the SEC such  amendments and  supplements to
the  Registration  Statement and the prospectus used in connection  therewith as
may be  necessary  to comply  with the  provisions  of the  Securities  Act with
respect to the disposition of all Registrable Shares covered by the Registration
Statement;

          (b) Furnish or otherwise  make  available to the Investors such number
of copies of a  prospectus,  including a preliminary  prospectus,  in conformity
with  the   requirements  of  the  Securities  Act,  and  such  other  documents
(including,  without  limitation,  prospectus  amendments and supplements as are
prepared by the Company in accordance  with Section 4(a) above) as the Investors
may reasonably request in order to facilitate the disposition of such Investors'
Registrable Shares;

          (c) Notify the  Investors,  at any time when a prospectus  relating to
the Registration Statement is required to be delivered under the Securities Act,

<PAGE>

of the happening of any event as a result of which the prospectus included in or
relating  to the  Registration  Statement  contains  an  untrue  statement  of a
material  fact or omits any fact  necessary to make the  statements  therein not
misleading;  and,  thereafter,  the Company will  promptly  prepare  (and,  when
completed,  give notice to each  Investor) a  supplement  or  amendment  to such
prospectus  so  that,  as  thereafter   delivered  to  the  purchasers  of  such
Registrable  Shares,  such prospectus will not contain an untrue  statement of a
material fact or omit to state any fact necessary to make the statements therein
not  misleading;  provided  that  upon such  notification  by the  Company,  the
Investors  will not  offer or sell  Registrable  Shares  until the  Company  has
notified the  Investors  that it has prepared a supplement  or amendment to such
prospectus and delivered  copies of such  supplement or amendment to the selling
Investors  (it being  understood  and agreed by the Company  that the  foregoing
proviso shall in no way diminish or otherwise impair the Company's obligation to
promptly prepare a prospectus  amendment or supplement as above provided in this
Section  4(c) and  deliver  copies of same as above  provided  in  Section  4(b)
hereof); and

          (d) Use  commercially  reasonable  efforts to register and qualify the
Registrable  Shares  covered  by the  Registration  Statement  under  such other
securities  or Blue  Sky  laws of such  jurisdictions  as  shall  be  reasonably
appropriate  in the opinion of the Company,  provided that the Company shall not
be required in connection  therewith or as a condition  thereto to qualify to do
business  or to file a general  consent to service of process in any such states
or jurisdictions,  and provided further that  (notwithstanding  anything in this
Agreement  to the  contrary  with  respect to the  bearing of  expenses)  if any
jurisdiction  in which any of such  Registrable  Shares shall be qualified shall
require that expenses incurred in connection with the  qualification  therein of
any such Registrable Shares be borne by the selling Investors,  then the selling
Investors shall, to the extent required by such jurisdiction, pay their pro rata
share of such qualification expenses.

     19.  FURNISH   INFORMATION.  It  shall  be  a condition   precedent  to the
obligations  of the Company to take any action  pursuant to this  Agreement that
the Investors shall furnish to the Company such  information  regarding them and
the securities held by them as the Company shall reasonably request and as shall
be required in order to effect any  registration by the Company pursuant to this
Agreement.

     20.  EXPENSES  OF  REGISTRATION. All  expenses incurred  in connection with
the registration of the Registrable Shares pursuant to this Agreement (excluding
underwriting,  brokerage and other selling commissions and discounts), including
without limitation all registration and qualification and filing fees, printing,
and fees and  disbursements  of counsel for the  Company,  shall be borne by the
Company.

     21.  DELAY OF REGISTRATION.   The Investors  shall  not  take any action to
restrain,  enjoin or  otherwise  delay  any  registration  as the  result of any
controversy   which  might  arise  with   respect  to  the   interpretation   or
implementation of this Agreement.

     22.  INDEMNIFICATION.

          (a) To  the extent permitted by law, the Company  will  indemnify  and
hold harmless each selling  Investor,  any investment  banking firm acting as an
underwriter for the selling Investors, any broker/dealer acting on behalf of any
selling Investors and each officer and director of such selling  Investor,  such
underwriter,  such  broker/dealer  and each person,  if any,  who controls  such
selling  Investor,  such underwriter or broker/dealer  within the meaning of the

<PAGE>

Securities Act,  against any losses,  claims,  damages or liabilities,  joint or
several, to which they may become subject under the Securities Act or otherwise,
insofar as such losses,  claims,  damages or liabilities  (or actions in respect
thereof) arise out of or are based upon any untrue or alleged  untrue  statement
of any material fact contained in the Registration Statement, in any preliminary
prospectus  or  final  prospectus  relating  thereto  or in  any  amendments  or
supplements to the Registration  Statement or any such preliminary prospectus or
final  prospectus,  or arise out of or are based  upon the  omission  or alleged
omission to state  therein a material  fact  required to be stated  therein,  or
necessary to make the statements therein not misleading; and will reimburse such
selling Investor, such underwriter,  broker/dealer or such officer,  director or
controlling person for any legal or other expenses  reasonably  incurred by them
in connection  with  investigating  or defending any such loss,  claim,  damage,
liability or action;  provided,  however, that the indemnity agreement contained
in this Section 8(a) shall not apply to amounts paid in  settlement  of any such
loss, claim, damage,  liability or action if such settlement is effected without
the consent of the Company (which consent shall not be  unreasonably  withheld),
nor shall the  Company  be  liable in any such case for any such  loss,  damage,
liability  or action to the  extent  that it arises  out of or is based  upon an
untrue statement or alleged untrue statement or omission made in connection with
the  Registration  Statement,  any  preliminary  prospectus or final  prospectus
relating thereto or any amendments or supplements to the Registration  Statement
or any such preliminary prospectus or final prospectus,  in reliance upon and in
conformity with written  information  furnished  expressly for use in connection
with the  Registration  Statement or any such  preliminary  prospectus  or final
prospectus by the selling  Investors,  any  underwriter  for them or controlling
person with respect to them.

          (b) To the  extent  permitted  by  law,  each  selling  Investor  will
severally and not jointly  indemnify and hold harmless the Company,  each of its
directors, each of its officers who have signed the Registration Statement, each
person,  if any, who controls the Company  within the meaning of the  Securities
Act, any investment  banking firm acting as  underwriter  for the Company or the
selling Investors,  or any broker/dealer  acting on behalf of the Company or any
selling Investors,  and all other selling Investors against any losses,  claims,
damages  or  liabilities  to which the  Company or any such  director,  officer,
controlling person, underwriter, or broker/dealer or such other selling Investor
may become subject to, under the  Securities  Act or otherwise,  insofar as such
losses, claims, damages or liabilities (or actions in respect thereto) arise out
of or are based upon any untrue or alleged untrue statement of any material fact
contained in the Registration  Statement or any preliminary  prospectus or final
prospectus,  relating  thereto  or in  any  amendments  or  supplements  to  the
Registration  Statement or any such preliminary  prospectus or final prospectus,
or arise out of or are based  upon the  omission  or alleged  omission  to state
therein a material fact  required to be stated  therein or necessary to make the
statements  therein not  misleading,  in each case to the extent and only to the
extent that such untrue  statement  or alleged  untrue  statement or omission or
alleged  omission was made in the  Registration  Statement,  in any  preliminary
prospectus  or  final  prospectus  relating  thereto  or in  any  amendments  or
supplements to the Registration  Statement or any such preliminary prospectus or
final  prospectus,  in reliance upon and in conformity with written  information
furnished  by the selling  Investor  expressly  for use in  connection  with the
Registration Statement,  or any preliminary prospectus or final prospectus;  and
such selling  Investor  will  reimburse any legal or other  expenses  reasonably
incurred  by the  Company or any such  director,  officer,  controlling  person,
underwriter,   broker/dealer  or  other  selling  Investor  in  connection  with
investigating or defending any such loss,  claim,  damage,  liability or action,
provided,  however,  that the liability of each selling Investor hereunder shall
be limited to the proceeds (net of underwriting  discounts and  commissions,  if
any)  received by such  selling  Investor  from the sale of  Registrable  Shares

<PAGE>

covered by the Registration Statement, and provided,  further, however, that the
indemnity  agreement  contained  in this Section 8(b) shall not apply to amounts
paid in settlement of any such loss, claim, damage,  liability or action if such
settlement is effected without the consent of those selling  Investor(s) against
which the  request  for  indemnity  is being made  (which  consent  shall not be
unreasonably withheld).

          (c) Promptly after receipt by an indemnified  party under this Section
8 of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party under this
Section 8, notify the indemnifying party in writing of the commencement  thereof
and the  indemnifying  party shall have the right to  participate in and, to the
extent the indemnifying party desires, jointly with any other indemnifying party
similarly  noticed,  to assume at its expense the defense  thereof  with counsel
mutually  satisfactory  to the  indemnifying  parties  with the  consent  of the
indemnified party which consent will not be unreasonably  withheld,  conditioned
or delayed.  In the event that the indemnifying  party assumes any such defense,
the  indemnified  party may participate in such defense with its own counsel and
at its own expense,  provided,  however,  that the counsel for the  indemnifying
party shall act as lead  counsel in all matters  pertaining  to such  defense or
settlement  of such  claim and the  indemnifying  party  shall only pay for such
indemnified   party's  expenses  for  the  period  prior  to  the  date  of  the
indemnifying  party's  participation  in such defense.  The failure to notify an
indemnifying  party  promptly  of  the  commencement  of  any  such  action,  if
prejudicial   to  his  ability  to  defend  such  action,   shall  relieve  such
indemnifying  party of any liability to the indemnified party under this Section
8, but the omission so to notify the indemnifying  party will not relieve him of
any liability  which he may have to any  indemnified  party otherwise other than
under this Section 8.

          (d) Notwithstanding  anything to the contrary herein, the indemnifying
party shall not be entitled to settle any claim,  suit or  proceeding  unless in
connection with such settlement the indemnified  party receives an unconditional
release with respect to the subject matter of such claim, suit or proceeding and
such  settlement  does not contain  any  admission  of fault by the  indemnified
party.

     23.  REPORTS UNDER THE EXCHANGE ACT. With a view to making available to the
Investors  the benefits of Rule 144 and any other rule or  regulation of the SEC
that may at any time permit the Investors to sell the Registrable  Shares to the
public without registration,  the Company agrees to use commercially  reasonable
efforts: (i) to make and keep public information  available,  as those terms are
understood and defined in the General Instructions to Form S-3, or any successor
or  substitute  form,  and in Rule  144,  (ii) to file  with the SEC in a timely
manner all  reports  and other  documents  required  to be filed by an issuer of
securities  registered  under the  Securities  Act or the Exchange Act, (iii) as
long as any Investor  owns any  Warrants or  Registrable  Shares,  to furnish in
writing upon such Investor's  request a written statement by the Company that it
has complied with the reporting  requirements  of Rule 144 and of the Securities
Act and the  Exchange  Act,  and to furnish to such  Investor a copy of the most
recent  annual or quarterly  report of the Company,  and such other  reports and
documents  so filed by the Company as may be  reasonably  requested  in availing
such Investor of any rule or regulation of the SEC permitting the selling of any
Registrable  Shares  without  registration  and (iv)  undertake  any  additional
actions  reasonably  necessary to maintain the  availability of the Registration
Statement or the use of Rule 144.

<PAGE>

     24.   DEFERRAL AND LOCK-UP.  Notwithstanding anything  in this Agreement to
the  contrary,  if  the  Company  shall  furnish  to  the  selling  Investors  a
certificate  signed by the President or Chief  Executive  Officer of the Company
stating  that the Board of  Directors  of the  Company  has made the good  faith
determination   (i)  that  continued  use  by  the  selling   Investors  of  the
Registration  Statement for purposes of effecting offers or sales of Registrable
Shares  pursuant  thereto would  require,  under the Securities  Act,  premature
disclosure in the Registration Statement (or the prospectus relating thereto) of
material,   nonpublic  information  concerning  the  Company,  its  business  or
prospects or any proposed material transaction  involving the Company, (ii) that
such  premature  disclosure  would be  materially  adverse to the  Company,  its
business or prospects or any such proposed  material  transaction  or would make
the  successful  consummation  by the Company of any such  material  transaction
significantly  less likely and (iii) that it is  therefore  advisable to suspend
the use by the  Investors of such  Registration  Statement  (and the  prospectus
relating  thereto)  for  purposes of  effecting  offers or sales of  Registrable
Shares  pursuant  thereto,  then the right of the selling  Investors  to use the
Registration  Statement  (and the prospectus  relating  thereto) for purposes of
effecting  offers  or sales of  Registrable  Shares  pursuant  thereto  shall be
suspended for a period (the "Suspension  Period") of not more than 90 days after
delivery by the Company of the certificate referred to above in this Section 10.
During the  Suspension  Period,  none of the  Investors  shall offer or sell any
Registrable  Shares pursuant to or in reliance upon the  Registration  Statement
(or the prospectus relating thereto).

     25.   TRANSFER OF REGISTRATION  RIGHTS.  None of the rights of any Investor
under this  Agreement  shall be transferred or assigned to any person unless (i)
such  person is a  Qualifying  Holder (as defined  below),  and (ii) such person
agrees to become a party to, and bound by, all of the terms and  conditions  of,
this  Agreement by duly executing and delivering to the Company an Instrument of
Adherence in the form attached as Exhibit A hereto. For purposes of this Section
11, the term "Qualifying  Holder" shall mean, with respect to any Investor,  any
direct transferee from such Investor of at least 50% of those Registrable Shares
held  or that  may be  acquired  by such  Investor.  None of the  rights  of any
Investor  under this  Agreement  shall be  transferred or assigned to any Person
(including,  without limitation,  a Qualifying Holder) that acquires Registrable
Shares in the event  that and to the  extent  that such  Person is  eligible  to
resell such Registrable Shares pursuant to Rule 144(k) of the Securities Act (or
any  successor or  substitute  rule) or may  otherwise  resell such  Registrable
Shares  pursuant  to an  exemption  from  the  registration  provisions  of  the
Securities Act.

     26.   ENTIRE AGREEMENT. This Agreement  constitutes and contains the entire
agreement and  understanding  of the parties with respect to the subject  matter
hereof, and it also supersedes any and all prior  negotiations,  correspondence,
agreements or understandings with respect to the subject matter hereof.

     27.   MISCELLANEOUS.

          (a) This Agreement may not be amended, modified or terminated,  and no
rights or  provisions  may be waived,  except  with the  written  consent of the
Majority Holders and the Company.

          (b) This Agreement  shall be governed by and construed and enforced in
accordance with the laws of the State of New York, and shall be binding upon and

<PAGE>

inure to the benefit of the parties hereto and their respective heirs,  personal
representatives,  successors or assigns,  provided that the terms and conditions
of Section 11 hereof are satisfied.  This  Agreement  shall also be binding upon
and  inure  to the  benefit  of any  transferee  of any of the  Warrants  or the
Registrable  Shares  provided that the terms and conditions of Section 11 hereof
are satisfied. Notwithstanding anything in this Agreement to the contrary, if at
any time any Investor shall cease to own any Warrants or Registrable Shares, all
of such Investor's rights under this Agreement shall immediately terminate.

          (c)   (i) Any  notices, reports or other  correspondence  (hereinafter
collectively referred to as "correspondence")  required or permitted to be given
hereunder  shall be sent by  courier  (overnight  or same  day) or  telecopy  or
delivered  by hand to the  party to whom  such  correspondence  is  required  or
permitted to be given hereunder. The date of giving any notice shall be the date
of its actual receipt.

                (ii) All correspondence to the Company shall be addressed in the
manner set forth in the Subscription Agreement.

                (iii) All correspondence to  any  Investor shall be sent to such
Purchaser at the address set forth in the Subscription Agreement.

          (d) Any entity may change the address to which correspondence to it is
to be addressed by notification as provided for herein.

          (e) The parties  acknowledge and agree that in the event of any breach
of this  Agreement,  remedies at law may be inadequate,  and each of the parties
hereto shall be entitled to seek specific  performance of the obligations of the
other parties hereto and such appropriate injunctive relief as may be granted by
a court of competent jurisdiction.

          (f) This Agreement may be executed in a number of counterparts, all of
which together shall for all purposes  constitute one Agreement,  binding on all
the parties  hereto  notwithstanding  that all such  parties have not signed the
same counterpart.

     IN WITNESS  WHEREOF,  the parties  hereto have executed  this  Registration
Rights Agreement as of the date and year first above written.
