interest that would accrue but for the occurrence of any such
proceeding whether or not such interest is an allowable claim in
such proceeding) remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Senior
Indebtedness of the Company; and

                    (iii)   in the event that, notwithstanding
the foregoing, any payment or distribution of assets of the

                                    -4-





         Subject to the payment in full in cash or cash equivalents
of all Senior Indebtedness of the Company, the holders of PIK
Notes shall be subrogated (without any duty on the part of the

effectuate, preserve or protect such subrogation) to the rights

the principal of and interest on the PIK Notes shall be paid in
full and, for the purpose of such subrogation, no payments or
distributions to the holders of Senior Indebtedness of the
Company of cash, property or securities otherwise distributable
to the holders of PIK Notes shall, as between the Company, its
creditors other than the holders of Senior Indebtedness of the
Company, and the holders of PIK Notes, be deemed to be a payment
by the Company to the holders of or on account of the Senior
Indebtedness of the Company. It is understood that the provisions
of this Section 7 (and of Section 7 of all other PIK Notes) are

intended to or shall impair, as between. the Company, its
creditors other than the holders of Senior Indebtedness of the
Company, and the holder of this Note, the obligation of the
Company, which is unconditional and absolute, to pay to the
holder of this Note the principal of and interest on this Note as
and when the same shall become due and payable in accordance with
its terms, or to affect the relative rights of the holders of PIK
Notes and creditors of the Company other than the holders of
Senior Indebtedness of the Company, nor shall anything herein
prevent the holder of this Note from exercising all remedies
otherwise permitted by applicable law upon default under this
Note, subject to the rights, if any, under this Section 7 of the
holders of Senior Indebtedness of the Company in respect of cash,
property or securities of the Company received upon the exercise
of any such remedy. Upon any payment or distribution of assets of
the Company referred to in this Section 7, the holder of this
Note shall be entitled to rely upon any order or decree of a
court of competent jurisdiction in which any proceedings of the
nature described in this Section are pending or upon a
certificate of the liquidating trustee or agent or other person
making any distribution to the holder of this Note for the
purpose of ascertaining the persons entitled to participate in
such distribution, the holders of Senior Indebtedness of the
Company and other indebtedness of the Company, the amount thereof
or payable thereon, the amount or amounts paid or distributed
thereon and all other facts pertinent thereto or to this Section
7.

                   (c)  No direct or indirect payments or

acceleration or otherwise, including by way of or on account of a
Claim, or the payment of principal of or interest on this Note)
shall be made if, at the time of such payment or distribution,
such payment or distribution is prohibited by the Credit
Agreement.

                   In the event that, notwithstanding the foregoing,
the Company shall make any payment or distribution of assets of
the Company of any kind or character, whether in cash, property
or securities, to the holder of this Note prohibited by the
foregoing provisions of this Section 7(c) (whether pursuant to
the terms of this Note or upon acceleration or otherwise,
including by way of or on account of a Claim, or the payment of
principal of or interest on this Note), then and in any such
event such payment or distribution shall, to the extent permitted
by law, be received and held in trust for the benefit of and be
paid over and delivered forthwith to the holders of the Senior
Indebtedness of the Company or their representative or
representatives.

                        The provisions of this Section 7(c) shall not
apply to any payment with respect to which Section 7(b) would be
applicable.

                   (d)   Except as provided in clause (b) or (c)
above, nothing contained in this Note shall affect the obligation
of the Company to make, or prevent the Company from making, at
any time, payments of principal or interest on this Note.

                   (e)  The holder of this Note shall take such
action as may be necessary or appropriate to effectuate the
subordination as provided in this Section 7, including, without
limitation, in the event of any dissolution, winding up,

business and assets of the Company, the immediate filing of a
claim for the unpaid balance of this Note in the form required in
such proceedings and using its best efforts to cause such claim
to be approved. If the holder of this Note does not file a proper
claim or proof of debt in the form required in such proceedings
prior to 30 days before the expiration of the time to file such
claim or claims, the holders of Senior Indebtedness of the
Company (or their representative or representatives) are hereby
authorized to file an appropriate claim for and on behalf of the
holder of this Note. Nothing herein shall be deemed to authorize
the holders of Senior Indebtedness of the Company to authorize or
consent to or accept or adopt on behalf of

                                    -6-

adjustment or composition affecting this Note or the rights of the

Indebtedness of the Company to vote in respect of the claim of the

any Senior Indebtedness of the Company to enforce subordination
as provided herein shall at any time in any way be prejudiced or
impaired by any act or failure to act on the part of the Company
or by any act or failure to act, in good faith, by any such
holder, or by any noncompliance by the Company with the terms of
this Note, regardless of any knowledge thereof which any such
holder may have or otherwise be charged with. The holders of
Senior Indebtedness of the Company may at any time and from time
to time, without the consent of or notice to the holder of this

         of the Company or any security therefor;


              (2)   sell, exchange, release or otherwise deal with

                                    -7-



              (5) apply any sums by whomsoever paid or however  
         realized to the Senior Indebtedness of the Company; or

jurisdiction.
