to which Escrowed Funds have not been released (according to their respective
interests), subject to the terms of this Escrow Agreement. Subject to the next
sentence, First Closing Deliveries deposited with the Escrow Agent by any party
and not released pursuant to Section 2(a) or (b) shall not be deemed to have
been delivered to any other party. Notwithstanding the foregoing, those
provisions (and only those provisions) of the Security Agreement appointing the

of the Collateral Agent shall be effective as of the date of this Escrow
Agreement as if the Security Agreement had been delivered by each of the parties
thereto to each of the other parties thereto. No person may give any notice,
instruction or direction to exercise any right of conversion under any Note that
has not been released pursuant to Section 2(a) or (b).

     5. The Escrow Agent hereby accepts its obligations under this Escrow
Agreement and represents that it has the corporate power and legal authority to
enter into this Escrow Agreement and perform its obligations hereunder. The
Escrow Agent further agrees that all property held by the Escrow Agent hereunder
shall be segregated from all other property held by the Escrow Agent and shall
be identified as being held in connection with this Escrow Agreement.
Segregation may be accomplished by appropriate identification on the books and
records of the Escrow Agent. The Escrow Agent agrees that its documents and
records with respect to the transactions contemplated hereby will be available
upon prior written request for examination by authorized representatives of
Holdings, Co-Borrowers and the Noteholders during regular business hours.

     6. The Escrow Agent shall be entitled to receive from Holdings, from time
to time, reimbursement for any reasonable costs and expenses incurred by it
under this Escrow Agreement. The Escrow Agent shall not have a lien upon, or any
other right whatsoever to payment from, the Escrowed Funds held hereunder by the
Escrow Agent, for or on account of such right to payment and reimbursement or
otherwise.

     7. The Escrow Agent shall not have any duties or responsibilities hereunder
except as expressly set forth herein and shall have no responsibility for
ascertaining or taking any action with respect to calls, conversions, exchanges,
maturities, tenders or other matters relating to the Escrowed Funds, other than
investments made by it pursuant to Section 1(c) above, whether or not the Escrow
Agent has or is deemed to have knowledge or notice of such matters,

                                      -5-
<PAGE>
or taking any steps to preserve rights against any parties with respect to any
Escrowed Funds. The Escrow Agent is not responsible in any manner whatsoever for
any failure or inability of any party other than the Escrow Agent to honor any
of the provisions of this Escrow Agreement. The Escrow Agent may consult with,
and obtain advice from, legal counsel in the event of any dispute under, or
concerning the construction of any of the provisions of or any of the Escrow
Agent's duties under, this Escrow Agreement, and the Escrow Agent will incur no
liability and will be fully protected in acting and refraining from acting in
good faith in accordance with the opinion and instruction of such counsel.

     8. The Escrow Agent shall be entitled to rely upon any notice, certificate,
affidavit, letter, document or other communication which is believed by the
Escrow Agent to be genuine and to have been signed or sent by the proper party
or parties, and may rely on statements contained therein without further inquiry
or investigation. The Escrow Agent shall not be deemed to have notice of or
knowledge about any matter unless provided in writing in accordance with Section
14 of this Escrow Agreement.

     9. The Escrow Agent shall not be liable for any action taken in accordance
with the terms of this Escrow Agreement, including without limitation, any
investment made in accordance with Section 1(c) or release in accordance with
Section 2. The Escrow Agent shall not be liable for any other action or failure
to act under or in connection with this Escrow Agreement, except for its own
gross negligence or willful misconduct.

     10. In the event that any escrow property shall be attached, garnished or
levied upon by any court order, or the delivery thereof shall be stayed or
enjoined by an order of a court, or any order, judgment or decree shall be made
or entered by any court order affecting the property deposited under this
Agreement, the Escrow Agent is hereby expressly authorized, in its sole
discretion exercised in good faith, to obey and comply with all writs, orders or
decrees so entered or issued, which it is advised by legal counsel of its own
choosing are binding upon it, and in the event that the Escrow Agent in good
faith obeys or complies with any such writ, order or decree it shall not be
liable to any of the parties hereto or to any other person, firm or corporation,
by reason of such compliance, notwithstanding that such writ, order or decree
may be subsequently reversed, modified, annulled, set aside or vacated.

     11. In the event of any disagreement between Holdings or Co-Borrowers and
the Noteholders, or any other person, resulting in an adverse claim to the
Escrowed Funds or First Closing Deliveries, the Escrow Agent shall be entitled
at its option to refuse to comply with any such claim and shall not be liable
for damages or interest to any such person or persons for its failure to comply
with such adverse claims; and the Escrow Agent shall be entitled to continue to
so refrain until:

     (a)  The rights of the adverse claimants shall have been finally
          adjudicated by a court of competent jurisdiction; or

     (b)  All differences are settled and the Escrow Agent has received a notice
          to that effect signed by all interested persons.

                                      -6-
<PAGE>
In the event of such disagreement, the Escrow Agent in its discretion may file a
suit in interpleader for the purpose of having the respective rights of the
claimants of such funds or other property adjudicated.

     12. Holdings and Co-Borrowers, and each of them, hereby agree to indemnify
the Escrow Agent, and hold the Escrow Agent harmless, from and against any and
all claims, costs, expenses, demands, judgments, losses, damages and
liabilities, including without limitation reasonable attorneys' fees and
disbursements, arising out of or in connection with this Escrow Agreement or any
action or failure to act by the Escrow Agent under or in connection with this
Escrow Agreement, including without limitation any action brought by the Escrow
Agent pursuant to Section 11 above, except such as may be caused by the gross
negligence or willful misconduct of the Escrow Agent.

     13. The Escrow Agent (in this Section, the "Existing Escrow Agent") may at
any time resign by giving written notice of such resignation to Holdings and the
Noteholders, and such resignation shall be effective 30 calendar days following
the date such notice is given. If any such resignation of the Existing Escrow
Agent shall occur, a successor Escrow Agent (the "Successor Escrow Agent") will
be appointed by Holdings and the Noteholders. Any such Successor Escrow Agent
shall deliver to Holdings and the Noteholders a written instrument accepting
such appointment and upon such delivery will succeed to all rights and duties of
the Existing Escrow Agent under this Escrow Agreement (and shall be deemed to be
the "Escrow Agent" for all purposes of this Escrow Agreement) and will be
entitled to receive from the Existing Escrow Agreement the Escrowed Funds (and
any earnings thereon) and the First Closing Deliveries, to hold pursuant to this
Escrow Agreement, upon which receipt the Existing Escrow Agent shall have no
further obligation under this Escrow Agreement. If Holdings and the Noteholders
are unable to agree upon a Successor Escrow Agent or have failed to appoint a
Successor Escrow Agent prior to the expiration of 30 calendar days following the
date of the notice of resignation, the Existing Escrow Agent shall petition any
court of competent jurisdiction for the appointment of a Successor Escrow Agent
or other appropriate relief, and any such resulting appointment will be binding
upon all parties to this Escrow Agreement. Upon acknowledgment by any Successor
Escrow Agent of receipt of the Escrowed Funds (including any earnings thereon)
and the First Closing Deliveries, the Existing Escrow Agent will be fully
relieved of all duties, responsibilities and obligations under this Escrow
Agreement, except with respect to actions previously taken or omitted to be
taken by the Existing Escrow Agent.

States mail, postage prepaid, and addressed as follows:
