WARRANTS

CUSIP TO COME

THIS
CERTIFIES THAT, for value received _______________________ is the registered
holder of a Warrant or Warrants expiring________, 2009 (the “Warrant”)
to purchase one fully paid and non-assessable share of Common Stock, par value
$.0001 per share (“Shares”), of Echo Healthcare Acquisition Corp., a
Delaware corporation (the “Company”), for each Warrant evidenced by
this Warrant Certificate. The Warrant entitles the holder thereof to purchase
from the Company, commencing on the later of (i) the Company’s completion
of a merger, capital stock exchange, asset acquisition or other similar business
combination and (ii) ___________, 2006, such number of Shares of the Company at
the price of $6.00 per share, upon surrender of this Warrant Certificate and
payment of the Warrant Price at the office or agency of the Warrant Agent,
Corporate Stock Transfer, Inc. (such payment to be made by check made payable to
the Warrant Agent), but only subject to the conditions set forth herein and in
the Warrant Agreement between the Company and Corporate Stock Transfer, Inc..
The Warrant Agreement provides that upon the occurrence of certain events the
Warrant Price and the number of Warrant Shares purchasable hereunder, set forth
on the face hereof, may, subject to certain conditions, be adjusted. The term
Warrant Price as used in this Warrant Certificate refers to the price per Share
at which Shares may be purchased at the time the Warrant is exercised.

No
fraction of a Share will be issued upon any exercise of a Warrant. If the holder
of a Warrant would be entitled to receive a fraction of a Share upon any
exercise of a Warrant, the Company shall, upon such exercise, round up to the
nearest whole number the number of Shares to be issued to such holder.

Upon
any exercise of the Warrant for less than the total number of full Shares
provided for herein, there shall be issued to the registered holder hereof or
his assignee a new Warrant Certificate covering the number of Shares for which
the Warrant has not been exercised.

Warrant
Certificates, when surrendered at the office or agency of the Warrant Agent by
the registered holder hereof in person or by attorney duly authorized in
writing, may be exchanged in the manner and subject to the limitations provided
in the Warrant Agreement, but without payment of any service charge, for another
Warrant Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants.

Upon
due presentment for registration of transfer of the Warrant Certificate at the
office or agency of the Warrant Agent, a new Warrant Certificate or Warrant
Certificates of like tenor and evidencing in the aggregate a like number of
Warrants shall be issued to the transferee in exchange for this Warrant
Certificate, subject to the limitations provided in the Warrant Agreement,
without charge except for any applicable tax or other governmental charge.

The
Company and the Warrant Agent may deem and treat the registered holder as the
absolute owner of this Warrant Certificate (notwithstanding any notation of
ownership or other writing hereon made by anyone), for the purpose of any
exercise hereof, of any distribution to the registered holder, and for all other
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice to the contrary.

This
Warrant does not entitle the registered holder to any of the rights of a
stockholder of the Company. The Company reserves the right to call the Warrant,
with the prior consent of Roth Capital Partners, LLC, at any time prior to its
exercise, with a notice of call in writing to the holders of record of the
Warrant, giving 30 days’ notice of such call at any time after the Warrant
becomes exercisable if the average closing sales price of the Shares has been at
least $11.50 per share for any 20 trading days within any 30 trading day period
ending on the third

business day prior to the date on which notice of such call
is given. The call price of the Warrants is to be $.01 per Warrant. Any Warrant
either not exercised or tendered back to the Company by the end of the date
specified in the notice of call shall be canceled on the books of the Company
and have no further value except for the $.01 call price.
