         3.2      Deferred Maintenance Obligations for Ciena Facilities. In
order to induce the Ciena Buyer to purchase the Ciena Facilities, PHCM has
agreed to reimburse Ciena for the cost of certain deferred maintenance repairs
required at the Ciena Facilities. Because PHCM does not have the funds to cover
the cost of the deferred maintenance repairs, Omega has agreed to assume PHCM's
obligations to Ciena with respect to the deferred maintenance repairs; and PHCM
has agreed to pay Omega for such assumption and for the other obligations of
Omega herein set forth the sum of $1,000,000, to be paid as follows:

                  (a)      (i) if the applicable Governmental Authority of the
                           State of Michigan has not issued the Final Audit
                           Report, PHCM will pay Omega $300,000 in immediately
                           available funds at the Ciena Closing, or (ii) if the
                           applicable Governmental Authority of the State of
                           Michigan has issued the Final Audit Report by the
                           time of the Ciena Closing, PHCM will pay Omega in
                           immediately available funds at the Ciena Closing an
                           amount equal to the greater of (1) $300,000, and (2)
                           the amount (not to exceed $600,000) by which the Net
                           Lowest Daily Cash Balance exceeds $850,000; and

                  (b)      at the Ciena Closing, PHCM will deliver to Omega the
                           Maintenance Obligation Note (as defined in Section
                           3.3 hereof).



         3.3      Maintenance Obligation Note. The Maintenance Obligation Note
to be delivered to Omega pursuant to Section 3.2(b) shall (1) be in the original
principal amount of $1,000,000, less the amount paid to Omega pursuant to
Section 3.2(a) hereof; (2) bear interest at the rate of eleven and one-quarter
percent (11.25%) per annum; (3) provide that PHCM's obligation to pay Contingent
Principal (as hereinafter defined) and interest thereon shall be contingent on
the consummation, on or before May 31, 2001, of a restructuring of the rest of
the Mariner Entities' obligations to Omega either as part of a restructuring or
a plan of reorganization approved by the Court; (4) be payable from PHCM's share
of Purchase Money Note Payments (as hereinafter defined) if, as and when they
are received; (5) be subject to mandatory prepayment in an amount equal to the
Applicable Prepayment Amount on each Mandatory Prepayment Date until the
non-contingent portion of the Maintenance Obligation Note has been paid in full
(and to the contingent portion, as well, once the applicable contingency has
been satisfied); (6) in any event be due and payable in full on the earlier of
(A) the tenth (10th) anniversary of the Ciena Closing, or (B) payment in full of
the Omega Loan; and (7) be substantially in the form attached hereto as Exhibit
B attached hereto. The term "Contingent Principal" shall mean a portion of the
principal amount of the Maintenance Obligation Note equal to $400,000.

         3.4      Partial Assignment of Purchase Money Financing Documents.
Contemporaneously with the Ciena Closing, PHCM shall assign, set over and
transfer to Omega (without recourse of any kind) an undivided fifty percent
(50%) interest in PHCM's right, title and interest in, to and under the Purchase
Money Financing Documents, in consideration of which PHCM shall receive a
$4,500,000 credit first against non-default interest owing on the Omega Loan and
second against the principal amount of the Omega Loan as of the Petition Date

         3.5      Pledge of PHCM's Interest in Purchase Money Financing
Documents. At the closing of the Ciena Transaction, PHCM shall pledge and
collaterally assign to Omega all of PHCM's right, title and interest in, to and
under the Purchase Money Financing Documents, as



                                       6
<PAGE>   7

security for the obligations of PHCM under the Maintenance Obligation Note (if
any) and the Omega Loan Documents. Such pledge shall be made pursuant to a
collateral assignment in form and substance reasonably acceptable to Omega.

         3.6      Servicing of Purchase Money Loan and Application of Funds. For
the administrative convenience of the Mariner Entities, Omega hereby agrees to
administer and function as servicer for the Purchase Money Loan, including,
without limitation, to maintain custody of the Purchase Money Financing
Documents for the benefit of PHCM and Omega, as their interests may appear, to
receive and apply payments made from time to time in respect of the Purchase
Money Loan by the Ciena Buyer and to give, on behalf of the holders thereof, all
notices to the Ciena Buyer and any guarantors of the Purchase Money Loan (each,
a "Ciena Guarantor") which are necessary or appropriate in respect of the
Purchase Money Loan. Copies of each such notice, and each notice (if any)
received by Omega from the Ciena Buyer or any Ciena Guarantor, shall be given to
PHCM as soon as reasonably practicable after receipt thereof by Omega. As
between the Ciena Buyer, on the one hand, and the holders of the Purchase Money
Note, on the other, payments received by Omega on the Purchase Money Note
("Purchase Money Note Payments") shall be applied against the Purchase Money
Loan obligations as provided in the Purchase Money Financing Documents. As
between PHCM, on the one hand, and Omega, on the other, each Purchase Money Note
Payment shall be applied as follows:

                  (a)      an amount equal to fifty percent (50%) of each
                           Purchase Money Note Payment shall be retained by
                           Omega; and

                  (b)      the balance of each Purchase Money Note Payment shall
                           be applied, first, against the outstanding balance of
                           the Maintenance Obligation Note (if any), until all
                           principal and interest thereunder have been paid in
                           full, and thereafter shall be applied against the
                           outstanding principal balance of the Omega Loan.

         Omega shall not modify any of the Purchase Money Financing Documents,
without the prior written consent of PHCM, which consent shall not be
unreasonably withheld or delayed so long as the proposed modification is not
adverse to the interests of PHCM or the other Mariner Entities. Upon the
occurrence of a Ciena Event of Default, Omega may after consultation with PHCM
exercise such remedies or forbear from exercising remedies as Omega determines
in good faith to be in the best interest of both PHCM and Omega. Omega shall not
be entitled to any fee for servicing the Purchase Money Loan, but Omega shall be
entitled to reimbursement, on a pro rata basis, for 50% of all out-of-pocket
expenses which it reasonably incurs in so doing. Omega shall service the
Purchase Money Loan in good faith and with the same degree of care that it
exercises in servicing loans made directly by it; but Omega shall be liable to
PHCM in connection with servicing the Purchase Money Loan only for acts of bad
faith, gross negligence or willful dishonesty.

         3.7      The Omega Improvement Loan. At the Ciena Closing, and as a
material inducement for the Ciena Buyer to close the Ciena Transaction, Omega
has agreed to enter into the Improvement Agreement with the Ciena Buyer,
pursuant to which Omega will agree to lend the Ciena Buyer up to Five Hundred
Thousand Dollars ($500,000) to be used to make certain


                                       7
<PAGE>   8

repairs and improvements to the Ciena Facilities, all on the terms and
conditions set forth in the Improvement Agreement. The Improvement Loan will be
secured by the same security documents that secure the Purchase Money Loan. PHCM
agrees that repayment of the Purchase Money Loan is subordinate and junior to
repayment of the Improvement Loan. So long as no Improvement Loan Event of
Default exists, payments received by either PHCM or Omega from the Ciena Buyer
will be applied to the Purchase Money Loan and the Omega Improvement Loan as
designated by the Ciena Buyer. However, from and after the occurrence of any
Improvement Loan Event of Default, and so long as the Improvement Loan Event of
Default continues in effect, as between Omega and the PHCM Entities, any payment
received from the Ciena Buyer by either Omega or the PHCM on either the Purchase
Money Loan or the Improvement Loan shall be applied first to the Improvement
Loan until the Improvement Loan is paid in full. Subject to the payment in full
of the Improvement Loan, the holders of the Purchase Money Loan shall be
subrogated to the rights of the holder of the Improvement Loan until the
obligations arising under the Purchase Money Financing Documents have been paid
in full. For purposes of such subrogation, no payments or distributions to the
holder of the Improvement Loan of any cash, properties or securities to which
the holders of the Purchase Money Loan would, except for the operation of this
Section 3.7, be entitled shall, as among Ciena Buyer, its creditors other than
the holder of the Improvement Loan, and the holders of the Purchase Money Loan
be deemed to be a payment on or distribution by Ciena Buyer to or on account of
the Improvement Loan.

         3.8      Accounting by Omega for Application of Funds. Within twenty
(20) days after each application of funds against the Omega Loan or the
indebtedness evidenced by the Maintenance Obligation Note pursuant to the
provisions of Section 3.6 hereof, and also within twenty (20) days after the
application of any Ciena Loan Payments against the Omega Improvement Loan, Omega
shall confirm such application in writing to PHCM.

thereby and the Agreement shall thereupon be reformed and construed and enforced
