                             STOCK ESCROW AGREEMENT

                  STOCK ESCROW AGREEMENT, dated as of _________, 2005
("Agreement"), by and among KBL HEALTHCARE ACQUISITION CORP. II, a Delaware
corporation ("Company"), ZACHARY BERK, MARLENE KRAUSS, M.D., MICHAEL KASWAN, THE
JULIANA PEARL BERK KRAUSS TRUST U/A DATED JULY 27, 1998, OLIVIA JADE BERK KRAUSS
TRUST U/A DATED JULY 27, 1998, ALEXANDER MAXWELL BERK KRAUSS TRUST U/A DATED
JULY 27, 1998, JOE WILLIAMSON, EILEEN MORE and SANDRA SANTOS (collectively
"Initial Stockholders") and CONTINENTAL STOCK TRANSFER & TRUST COMPANY, a New
York corporation ("Escrow Agent").

                  WHEREAS, the Company has entered into an Underwriting
Agreement, dated _____________, 2005 ("Underwriting Agreement"), with
EarlyBirdCapital, Inc. ("EBC") acting as representative of the several
underwriters (collectively, the "Underwriters"), pursuant to which, among other
matters, the Underwriters have agreed to purchase 5,000,000 units ("Units") of
the Company. Each Unit consists of one share of the Company's Common Stock, par
value $.0001 per share, and two Warrants, each Warrant to purchase one share of
Common Stock, all as more fully described in the Company's final Prospectus,
dated _____________, 2005 ("Prospectus") comprising part of the Company's
Registration Statement on Form S-1 (File No. 333-_______) under the Securities
Act of 1933, as amended ("Registration Statement"), declared effective on
_____________, 2005 ("Effective Date").

                  WHEREAS, the Initial Stockholders have agreed as a condition
of the sale of the Units to deposit their shares of Common Stock of the Company,
as set forth opposite their respective names in Exhibit A attached hereto
(collectively "Escrow Shares"), in escrow as hereinafter provided.

                  WHEREAS, the Company and the Initial Stockholders desire that
the Escrow Agent accept the Escrow Shares, in escrow, to be held and disbursed
as hereinafter provided.

                  IT IS AGREED:

         1. Appointment of Escrow Agent. The Company and the Initial
Stockholders hereby appoint the Escrow Agent to act in accordance with and
subject to the terms of this Agreement and the Escrow Agent hereby accepts such
appointment and agrees to act in accordance with and subject to such terms.

         2. Deposit of Escrow Shares. On or before the Effective Date, each of
the Initial Stockholders shall deliver to the Escrow Agent certificates
representing his respective Escrow Shares, to be held and disbursed subject to
the terms and conditions of this Agreement. Each Initial Stockholder
acknowledges that the certificate representing his Escrow Shares is legended to
reflect the deposit of such Escrow Shares under this Agreement.

         3. Disbursement of the Escrow Shares. The Escrow Agent shall hold the
Escrow Shares until the third anniversary of the Effective Date ("Escrow
Period"), on which date it shall, upon written instructions from each Initial
Stockholder, disburse each of the Initial Stockholder's Escrow Shares to such
Initial Stockholder; provided, however, that if the Escrow Agent is notified by
the Company pursuant to Section 6.7 hereof that the Company is being liquidated
at any time during the Escrow Period, then the Escrow Agent shall promptly
destroy the certificates representing the Escrow Shares; provided further,
however, that if, after the Company consummates a Business Combination (as such
term is defined in the Registration Statement), it (or the surviving entity)
subsequently consummates a liquidation, merger, stock exchange or other similar
transaction which results in all of the stockholders of such entity having the
right to exchange their shares of Common Stock for cash, securities or other
property, then the Escrow Agent will, upon receipt of a certificate, executed by
the Chief Executive Officer or Chief Financial Officer of the Company, in form
reasonably acceptable to the Escrow Agent, that such transaction is then being
consummated, and release the Escrow Shares to the Initial Stockholders upon
consummation of the transaction so that they can similarly participate. The
Escrow Agent shall have no further duties hereunder after the disbursement or
destruction of the Escrow Shares in accordance with this Section 3.

         4. Rights of Initial Stockholders in Escrow Shares.

                  4.1 Voting Rights as a Stockholder. Subject to the terms of
the Insider Letter described in Section 4.4 hereof and except as herein
provided, the Initial Stockholders shall retain all of their rights as
stockholders of the Company during the Escrow Period, including, without
limitation, the right to vote such shares.

                  4.2 Dividends and Other Distributions in Respect of the Escrow
Shares. During the Escrow Period, all dividends payable in cash with respect to
the Escrow Shares shall be paid to the Initial Stockholders, but all dividends
payable in stock or other non-cash property ("Non-Cash Dividends") shall be
delivered to the Escrow Agent to hold in accordance with the terms hereof. As
used herein, the term "Escrow Shares" shall be deemed to include the Non-Cash
Dividends distributed thereon, if any.

                  4.3 Restrictions on Transfer. During the Escrow Period, no
sale, transfer or other disposition may be made of any or all of the Escrow
Shares except (i) by gift to a member of Initial Stockholder's immediate family
or to a trust, the beneficiary of which is an Initial Stockholder or a member of
an Initial Stockholder's immediate family, (ii) by virtue of the laws of descent
and distribution upon death of any Initial Stockholder, or (iii) pursuant to a
qualified domestic relations order; provided, however, that such permissive
transfers may be implemented only upon the respective transferee's written
agreement to be bound by the terms and conditions of this Agreement and of the
Insider Letter signed by the Initial Stockholder transferring the Escrow Shares.
Notwithstanding the foregoing, with respect to the Escrow Shares issued in the
name of Michael Kaswan, any such Escrow Shares that do not vest in Mr. Kaswan
pursuant to that certain Vesting Agreement entered into between Michael Kaswan,
on the one hand, and Drs. Zachary Berk and Marlene Krauss, on the other hand,
shall revert back in equal proportions to Drs. Berk

                                       2

and Krauss and continued to be held in Escrow for the remainder of the Escrow
Period. During the Escrow Period, the Initial Stockholders shall not pledge or
grant a security interest in the Escrow Shares or grant a security interest in
their rights under this Agreement.

                  4.4 Insider Letters. Each of the Initial Stockholders has
executed a letter agreement with EBC and the Company, dated as indicated on
Exhibit A hereto, and which is filed as an exhibit to the Registration Statement
("Insider Letter"), respecting the rights and obligations of such Initial
Stockholder in certain events, including but not limited to the liquidation of
the Company.

         5. Concerning the Escrow Agent.

                  5.1 Good Faith Reliance. The Escrow Agent shall not be liable
for any action taken or omitted by it in good faith and in the exercise of its
own best judgment, and may rely conclusively and shall be protected in acting
upon any order, notice, demand, certificate, opinion or advice of counsel
(including counsel chosen by the Escrow Agent), statement, instrument, report or
other paper or document (not only as to its due execution and the validity and
effectiveness of its provisions, but also as to the truth and acceptability of
any information therein contained) which is believed by the Escrow Agent to be
genuine and to be signed or presented by the proper person or persons. The
Escrow Agent shall not be bound by any notice or demand, or any waiver,
modification, termination or rescission of this Agreement unless evidenced by a
writing delivered to the Escrow Agent signed by the proper party or parties and,
if the duties or rights of the Escrow Agent are affected, unless it shall have
given its prior written consent thereto.

                   5.2 Indemnification. The Escrow Agent shall be indemnified
and held harmless by the Company from and against any expenses, including
counsel fees and disbursements, or loss suffered by the Escrow Agent in
connection with any action, suit or other proceeding involving any claim which
in any way, directly or indirectly, arises out of or relates to this Agreement,
the services of the Escrow Agent hereunder, or the Escrow Shares held by it
hereunder, other than expenses or losses arising from the gross negligence or
willful misconduct of the Escrow Agent. Promptly after the receipt by the Escrow
Agent of notice of any demand or claim or the commencement of any action, suit
or proceeding, the Escrow Agent shall notify the other parties hereto in
writing. In the event of the receipt of such notice, the Escrow Agent, in its
sole discretion, may commence an action in the nature of interpleader in an
appropriate court to determine ownership or disposition of the Escrow Shares or
it may deposit the Escrow Shares with the clerk of any appropriate court or it
may retain the Escrow Shares pending receipt of a final, non-appealable order of
a court having jurisdiction over all of the parties hereto directing to whom and
under what circumstances the Escrow Shares are to be disbursed and delivered.
The provisions of this Section 5.2 shall survive in the event the Escrow Agent
resigns or is discharged pursuant to Sections 5.5 or 5.6 below.

                  5.3 Compensation. The Escrow Agent shall be entitled to
reasonable compensation from the Company for all services rendered by it
hereunder. The Escrow Agent shall also be entitled to reimbursement from the
Company for all expenses paid or incurred by it in the administration of its
duties hereunder including, but not limited to, all counsel, advisors' and
agents' fees and disbursements and all taxes or other governmental charges.

                  5.4 Further Assurances. From time to time on and after the
date hereof, the Company and the Initial Stockholders shall deliver or cause to
be delivered to the Escrow Agent such further documents and instruments and
shall do or cause to be done such further acts as the

                                       3

Escrow Agent shall reasonably request to carry out more effectively the
provisions and purposes of this Agreement, to evidence compliance herewith or to
assure itself that it is protected in acting hereunder.

                  5.5 Resignation. The Escrow Agent may resign at any time and
be discharged from its duties as escrow agent hereunder by its giving the other
parties hereto written notice and such resignation shall become effective as
hereinafter provided. Such resignation shall become effective at such time that
the Escrow Agent shall turn over to a successor escrow agent appointed by the
Company, the Escrow Shares held hereunder. If no new escrow agent is so
appointed within the 60 day period following the giving of such notice of
resignation, the Escrow Agent may deposit the Escrow Shares with any court it
reasonably deems appropriate.

                  5.6 Discharge of Escrow Agent. The Escrow Agent shall resign
and be discharged from its duties as escrow agent hereunder if so requested in
writing at any time by the other parties hereto, jointly, provided, however,
that such resignation shall become effective only upon acceptance of appointment
by a successor escrow agent as provided in Section 5.5.

                  5.7 Liability. Notwithstanding anything herein to the
contrary, the Escrow Agent shall not be relieved from liability hereunder for
its own gross negligence or its own willful misconduct.

         6. Miscellaneous.

                  6.1 Governing Law. This Agreement shall for all purposes be
deemed to be made under and shall be construed in accordance with the laws of
