charges incident to such conveyance, grant and assignment, including counsel
fees, escrow fees, recording fees, title insurance premiums and all applicable
taxes (other than any income or franchise taxes of Owner and PFM)

                                      -16-
<PAGE>

delivery of said deed and other instruments. Upon the completion of such
purchase, but not prior thereto (whether or not any delay or failure in the
completion of such purchase shall be the fault of Owner or PFM), the Prime Lease
and this Sublease shall terminate, except with respect to obligations and
liabilities of the Partnership hereunder, actual or contingent, which have
arisen on or prior to such date of purchase.

(i) or (ii) of paragraph 12(a), the Partnership is not required to give notice
of its intention to terminate this Sublease, then this Sublease shall continue
in full effect, and the Partnership shall repair any damage to the Premises
caused by such event in conformity with the requirements of paragraph 11(a) so
as to restore the Premises (as nearly as practicable) to the condition and
market value thereof immediately prior to such occurrence. The Partnership shall
be entitled to receive the Net Proceeds payable in connection with such
occurrence, but only against certificates of the Partnership delivered to PFM
from time to time as such work or repair progresses, each such certificate
describing the work of repair for which the Partnership is requesting payment
and the cost incurred by the Partnership in connection therewith and stating
that the Partnership has not theretofore received payment for such work. Any Net
Proceeds remaining after final payment has been made for such work shall be paid
to the Partnership if such amounts are less than $5,000. If such excess proceeds
are $5,000 or more, they shall be retained by PFM and (i) the Basic Amount set
forth in Schedule C shall be reduced by an amount equal to such Net Proceeds so
retained by PFM and (ii) each installment of Basic Rent payable on and after the
first Payment Date occurring three months or more after the final payment to the
Partnership for such work

                                      -17-
<PAGE>

shall be reduced by a fraction thereof, the numerator of which shall be the
amount so retained by PFM and the denominator of which shall be the Basic Amount
prior to the reduction thereof referred to in clause (i) above. In the event of
any temporary requisition, this Sublease shall remain in full effect for the
remainder of the term hereof and the Partnership shall be entitled to receive
the entire Net Proceeds payable during the remainder of the term hereof by
reason of such requisition. If the cost of any repairs required to be made by
the Partnership pursuant to this paragraph 12(c) shall exceed the amount of such
Net Proceeds, the deficiency shall be paid by the Partnership.

                      from time to time included after "extended coverage"
                      policies, in amounts sufficient to prevent Owner, PFM or
                      the Partnership from becoming a co-insurer of any loss but
                      in any event in amounts not less than 90% of the actual
                      replacement value of the Improvements, exclusive of
                      foundations and excavations and less physical
                      depreciation.

               (ii)   General public liability insurance against claims for
                      bodily injury, death or property damage occurring on, in
                      or about the Premises and adjoining streets and sidewalks,
                      in the minimum amounts of $500,000 for bodily injury or
                      death to any one person, $1,000,000 for any one accident,
                      and $1,000,000 for property damage.

               (iii)  Workmen's compensation insurance to the extent required by
                      the law of the state in which the Premises are located and
                      to the extent necessary to protect Owner, PFM, the
                      Partnership and the Premises against workmen's
                      compensation claims.

               (iv)   Such other insurance, in such amounts and against such
                      risks, as is commonly obtained in the case of property
                      similar in use to the Premises are located, including war-
                      risk insurance when and to the

                                      -18-
<PAGE>

                    extent obtainable from the United States Government or any
                    agency thereof.

Such insurance shall be written by companies of nationally recognized financial
standing legally qualified to issue such insurance in the state in which the
Premises are located and shall name as insured parties Owner, PFM and the
Partnership as their interests may appear.

          (b)  Every such policy (other than any general public liability or
workmen's compensation policy) shall bear a first mortgagee endorsement in favor
of the mortgagee or beneficiary (the Mortgagee) under any instrument creating a
first lien on owner's interest in the Premises (the Mortgage); and any loss
under any such policy shall be payable to the Mortgagee to be held and applied
pursuant to paragraph 12(c). Every policy referred to in paragraph 13(a) shall
provide that it will not be cancelled except after 30 days' written notice to
owner, PFM and the Mortgagee and that it shall not be invalidated by any act or
neglect of Owner, PFM or the Partnership, nor by occupancy of the Premises for
purposes more hazardous than permitted by such policy, nor by any foreclosure or
other proceedings relating to the Premises, nor by change in title to the
Premises.

          (c)  The Partnership shall deliver to the Mortgagee original or
duplicate policies or certificates of insurers, satisfactory to the Mortgagee,
evidencing the existence of all insurance which is required to be maintained by
the Partnership hereunder, such delivery to be made (i) promptly after the
execution and delivery hereof and (ii) within 30 days prior to the expiration of
any such insurance. The Partnership shall not obtain or carry separate insurance
concurrent in form or contributing in the event of loss with that required by
this paragraph 13 unless Owner and PFM are named insureds therein, with loss
payable as provided herein. The Partnership shall immediately notify owner and
PFM whenever any such separate insurance is

                                      -19-
<PAGE>

obtained and shall deliver to the Mortgagee the policies or certificates
evidencing the same. Any insurance required hereunder may be provided under
blanket policies with a deductible of not more than $50,000. PFM acknowledges
that PFM-EG is, pursuant to the Operating Agreement, obligated to furnish
certain insurance coverage to the Partnership; to the extent that PFM-EG shall
procure and maintain the Partnership shall not be required to provide
corresponding coverage hereunder.

     14.  Right of First Refusal. If at any time during the Partnership Term of
          ----------------------
this Sublease, owner receives a bona fide offer to purchase the Leased Land and
Leased Improvements (or any part thereof), other than a bid or offer to purchase
the Leased Land and Leased Improvements at any sale incidental to the exercise
of any remedy provided for in a mortgage or similar instrument creating a lien
thereon (the Mortgage), which owner desires to accept, Owner will, prior to
accepting the same, give PFM an opportunity to purchase the Leased Land and
Leased Improvements (or such part thereof) upon the same terms and conditions
contained in such offer and PFM shall pass on that opportunity to the
Partnership. The Partnership must exercise its rights within 7 days of receiving
written notice of the full terms of sale and owner's intention to sell which
shall be delivered to the Partnership by PFM within 5 days of PFM's receipt
thereof. If the time periods for the right of first refusal granted PFM by Owner
under the Prime Lease are extended by amendment of the Prime Lease at the time
of closing of the Permanent Financing, then the time periods in the preceding
sentence shall also be extended by amendment to this Sublease, provided that PFM
shall have a reasonable period within which to exercise the right of first
refusal under the Prime Lease as so amended should the Partnership fail to do so
under this Sublease as amended.  If the Partnership fails to exercise its right
to purchase, then PFM is free

                                      -20-
<PAGE>

to do so, and, if both the Partnership and PFM fail to do so, then the Owner may
proceed to sell the Leased Land and Leased Improvements (or such part thereof)
in accordance with the terms of the offer. If such sale is not made, the
Partnership's right to purchase shall be reinstated as aforesaid, and if only a
part of the Leased Land and Leased Improvements is sold in such manner, the
Partnership's rights to purchase shall remain as to the balance of the Leased
Land and Leased Improvements and are coupled with an interest. Except as
provided above with respect to a sale incidental to the exercise of a remedy
under a Mortgage, this right in favor of the Partnership shall be binding upon
any grantee of the Leased Land and Leased Improvements, or part thereof
(including PFM) during the Partnership Term is in effect so that the Partnership
shall have such rights from the owners of the Leased Land and Leased
Improvements during the Partnership Term in the event the Partnership does not
exercise its rights in earlier sales. The rights granted the Partnership under
this paragraph are coupled with an interest in the Leased Land and Leased
Improvements. Any such conveyance or transfer pursuant to this paragraph 14
shall be expressly subject to this Sublease and any Mortgage.

     15.  Amendments at Closing of the Permanent Financing.  At the time the
          ------------------------------------------------
closing of the Permanent Financing PFM agrees to convey the New Land and New
Improvements to Owner, provided that, concurrently with such conveyance, the
Prime Lease shall be amended in a reasonable manner acceptable to PFM so that
the Prime Lease as amended, shall provide for Basic Rent in an amount sufficient
to maintain equity payments due Owner plus an amount equal to debt service
payable to CA under the New Mortgage Financing for the full twelve year period
from the date of closing of the Permanent Financing, to include the New and New
Improvements as  part of the Premises under the Prime Lease and to make such
other changes and amendments

                                      -21-
<PAGE>

required or appropriate to accommodate the terms and requirement of the New
Mortgage Financing and the Owner in connection therewith. PFM shall use
reasonable efforts to include in such amendment provisions providing for the
Owner to acknowledge and consent to this Sublease (as the same shall be amended
a provided herein), and to provide that Owner shall, in the event of a default
under the Prime Lease (as amended), refrain from exercising any rights or
remedies which it then may have without first providing the Partnership with
written notice of the occurrence of such default and the reasonable opportunity
to cure the same. Concurrently therewith, PFM and the Partnership shall amend
this Sublease to reflect essentially the same rentals and terms as the Prime
Lease, as so amended, on a pass through basis for a term of twelve (12) years;
provided that paragraph 9A hereof shall remain in force and effect. If for any
reason the Permanent Financing does not close at the time the construction under
the Construction Agreement is completed, PFM shall negotiate extensions and
amendments to this Sublease in good faith.

       16.  Assignment and Subletting. The Partnership may sublet the Premises
            -------------------------
or assign its interests hereunder, provided that each sublease shall expressly
be made subject to the provisions hereof and the Prime Lease. No such assignment
or sublease shall modify or limit any right or Power of PFM hereunder or the
Owner under the Prime Lease, or affect or reduce any obligation of the
Partnership hereunder, and all such obligations shall continue in full effect as
obligations of a principal and not of a guarantor or surety, as though no
assignment or subletting had been made. Neither this Sublease nor the term
hereby demised shall be mortgaged by the Partnership, nor shall the Partnership
mortgage or pledge its interests in any sublease of the Premises or the rentals
payable thereunder unless such pledge or mortgage has been approved in advance
by

                                      -22-
<PAGE>

PFM, which approval shall not be unreasonably withheld. The Partnership shall,
within 7 days after the execution of any such sublease or assignment, deliver a
conformed copy there of to PFM. Permitted Contests. The Partnership shall not be
                                ------------------
required, nor shall PFM have the right, to pay, discharge or remove any tax,
assessment, levy, fee, rent, charge, lien or encumbrance, or to comply with any
legal requirement applicable to the Premises or the use thereof, as long as the
Partnership shall contest the existence, amount or validity thereof by
appropriate proceedings which shall prevent the collection of or other
realization upon the tax, assessment, levy, fee, rent, charge, lien or
encumbrance so contested, and the sale, forfeiture or loss of the Premises or
any Basic Rent or any additional rent, to satisfy the same, and which shall not
affect the payment of any Basic Rent or any additional rent, provided that such
contest shall not subject PFM to the risk of any criminal liability. The
Partnership shall give such reasonable security as may be demanded by PFM, Owner
or the Mortgagee to insure payment of such tax, assessment, levy, fee, rent,
charge, lien or encumbrance and to prevent any sale or forfeiture of the
Premises of such non-payment.

     17.  Conditional Limitations; Default Provision.
          ------------------------------------------

          (a)  Any of the following occurrences or acts shall constitute an
event of default under this Sublease: (i) if the Partnership shall (1) fail to
pay any Basic Rent, additional rent or other sum required to be paid by the
Partnership hereunder, or (2) fail to observe or perform any other provision
hereof and such failure shall continue for 25 days after written notice thereof
to the Partnership; or (ii) if the Partnership shall file a petition in
bankruptcy or for reorganization or for an arrangement pursuant to any federal
or state bankruptcy law or any similar federal or state law, or shall be
adjudicated a bankrupt or become insolvent or shall make

                                      -23-
<PAGE>

an assignment for the benefit of creditors or shall admit in writing its
inability to pay its debts generally as they become due, or if a petition or
answer proposing the adjudication of the Partnership as a bankrupt or its
reorganization pursuant to any federal or state bankruptcy law or any similar
federal or state law shall be filed in any court and the Partnership shall
consent to or acquiesce in the filing thereof or such petition or answer shall
not be discharged or denied within 90 days after the filing thereof, or (iii) if
a receiver, trustee or liquidator of the Partnership or of all or substantially
all of the assets of the Partnership or of the Premises shall be appointed in
any proceeding brought by the Partnership or if any such receiver, trustee or
liquidator shall be appointed in any proceeding brought against the Partnership
and shall not be discharged within 90 days after such appointment, or if the
Partnership shall consent to or acquiesce in such appointment; or (iv) if the
Premises shall have been left unoccupied and unattended for a period of 30 days.

          (b)  If an event of default shall have happened and be continuing, PFM
shall have the right to give the Partnership notice of PFM's intention to
terminate the term of this Sublease on a date not less than 3 days after the
date of such notice. Upon the giving of such notice, the term of this Sublease
and the estate hereby granted shall expire and terminate on such date as fully
and completely and with the same effect as if such date were the date herein
fixed for the expiration of the term of this Sublease, and all rights of the
Partnership hereunder shall expire and terminate, but the Partnership shall
remain liable as hereinafter provided.

          (c)  if an event of default shall have happened and be continuing, PFM
shall have the immediate right, whether or not the term of this Sublease shall
have been terminated pursuant to paragraph 18(b), to re-enter and repossess the
Premises by summary proceedings,

                                      -24-
<PAGE>

ejectment or in any manner PFM determines to be necessary or desirable and the
right to remove all persons and property therefrom. PFM shall be under no
liability by reason of any such reentry or repossession or removal. No such re-
entry or repossession of the Premises shall be construed as an election by PFM
to terminate the term of this Sublease unless a notice of such intention is
given to the Partnership pursuant to paragraph 18(b), or unless such termination
is decreed by a court of competent jurisdiction.

          (d)  At any time or from time to time after the re-entry or
repossession of the Premises pursuant to paragraph 18(c), whether or not the
term of this Sublease shall have been terminated pursuant to paragraph 18(b),
PFM may (but shall be under no obligation to) relet the Premises for the account
of the Partnership, in the name of the Partnership or PFM or otherwise, without
notice to the Partnership, for such term or terms and on such conditions and for
such uses as PFM, in its absolute discretion, may determine. PFM may collect and
receive any rents payable by reasons of such reletting. PFM shall not be liable
for any failure to relet the Premises or for any failure to collect any rent due
upon any such reletting.

          (e)  No expiration or termination of the term of this Sublease
pursuant to Paragraph 18(b), by operation of law or otherwise, and no re-entry
or repossession of the Premises pursuant to paragraph 18(c) or otherwise, and no
reletting of the Premises pursuant to paragraph 18(d) or otherwise, shall
relieve the Partnership of its liabilities and obligations hereunder, all of
which shall survive such expiration, termination, re-entry, repossession or
reletting.

          (f)  In the evert of any expiration or termination of the term of this
Sublease or re-entry or repossession of the Premises by reason of the occurrence
of an event of default, the

                                      -25-
<PAGE>

Partnership will pay to PFM all Basic Rent, additional rent and other sums
required to be paid by the Partnership to and including the date of such
expiration, termination, re-entry or repossession, and whether or not the
Premises shall have been relet, be liable to PFM from, and shall pay to PFM, as
liquidated and agreed current damages: (i) all Basic Rent, additional rent and
other sums which would be payable under this Sublease by the Partnership in the
absence of such expiration, termination, re-entry or repossession, lease (ii)
the net proceeds, if any, of any reletting effected for the account of the
Partnership pursuant to paragraph 18(d), after deducting from such proceeds all
expenses of PFM and Owner in connection with such reletting (including all
repossession costs, brokerage commissions, reasonable attorneys' fees and
expenses, employees' expenses, alteration costs and expenses of preparation for
such reletting). The Partnership will pay such current damages on the days on
which Basic Rent would be payable under this Sublease in the absence of such
expiration, termination, re-entry, or repossession, and PFM shall be entitled to
recover the same from the Partnership on each such day.

          (g)  At any time after such expiration or termination of the term of
this Sublease or re-entry or repossession of the Premises by reason of the
occurrence of an event of default, whether or not PFM shall have collected any
current damages pursuant to paragraph 18(f), PFM shall be entitled to recover
from the Partnership, and the Partnership will pay to PFM on demand, as and for
liquidated and agreed final damages for the Partnership's default and in lieu of
all current damages beyond the date of such demand (it being agreed that it
would be impracticable or extremely difficult to fix the actual damages), an
amount equal to the excess, if any, of (a) all Basic Rent, additional rent and
other sums which would be payable under this Sublease from the date of such
demand (or, if it be earlier, the date to which the Partnership shall

                                      -26-
<PAGE>

have satisfied in full its obligations under paragraph 18(f) to pay current
damages) for what would be the then unexpired term of this Sublease in the
absence of such expiration, termination, re-entry or repossession, discounted at
the rate of 5% per annum over (b) the then fair rental value of the Premises
(determined by applying a discount rate of 5% per annum) for the same period. If
any law shall limit the amount of such liquidated final damages to less than the
amount above agreed upon, PFM shall be entitled to the maximum amount allowable
under such law.

     18.  Additional Rights of PFM.
          ------------------------

          (a)  No right or remedy hereunder shall be exclusive of any other
right or remedy, but shall be cumulative and in addition to any other right or
remedy hereunder or now or hereafter existing. Failure to insist upon the str ct
performance of any provision hereof or to exercise any option, right, power or
remedy contained herein shall not constitute a waiver or relinquishment thereof
for the future. Receipt by PFM of any Basic Rent, additional rent or other sums
payable hereunder with knowledge of the breach of any provision hereof shall not
constitute a waiver of such breach, and no waiver by PFM of any provision hereof
shall be deemed to have been made unless made in writing. PFM shall be entitled
to injunctive relief increase of the violation, or attempted or threatened
violation, of any of the provisions hereof, or to a decree compelling
performance of any of the provisions hereof, or to any other remedy allowed to
PFM by law.

          (b)  The Partnership hereby waives and surrenders for itself and all
those claiming under it, including creditors of all kinds, (i) any right and
privilege which it or any of them may have to redeem the Premises or to have a
continuance of this Sublease after

                                      -27-
<PAGE>

termination of the Partnership's right of occupancy by order or judgment of any
court or by any legal process or writ, or under the terms of this Sublease, or
after the termination of the term of this Sublease as herein provided, and (ii)
the benefits of any law which exempts property from liability for debt or for
distress for rent.

          (c)  If the Partnership shall be in default in the performance of any
of its obligations hereunder, the Partnership shall pay to PFM, on demand, all
expenses incurred by PFM and Owner as a result thereof, including reasonable
attorneys' fees and expenses. If PFM or owner, or both, shall be made a party to
any litigation commenced against the Partnership and the Partnership, at its'
expense, shall fail to provide PFM with counsel approved by PFM and owner, the
Partnership shall pay all costs and reasonable attorneys' fees incurred by PFM
and Owner in connection with such litigation (including all appeals).

     19.  Notices, Demands and Other Instruments.
          --------------------------------------

          (a)  All notices, demands, designations, certificates, requests,
offers, consents, approvals and other instruments given pursuant to this
Sublease shall be in writing and shall be validly given when mailed by prepaid
registered mail, (i) if to PFM, addressed to PFM at its address set forth above,
and (ii) if to the Partnership, addressed to the Partnership at its address set
forth above. PFM and the Partnership each may from time to time specify any
address in the United States as its address for purposes of this Sublease by
giving 15 days' notice to the other party.

          (b)  PFM agrees to forward to the Partnership immediately upon receipt
thereof copies of all notices from Owner and to provide concurrent copies of
PFM's notices to Owner under the Prime Lease.

                                      -28-
<PAGE>

     20.  Estoppel Certificates.
          ---------------------

          (a)  Each party will, from time to time, upon 15 days' prior request
by the other party, execute, acknowledge and deliver to the requesting party a
certificate stating that this Sublease is unmodified and in full effect (or, if
there have been modifications, that this Sublease is in full effect as modified,
and setting forth such modifications) and the dates to which Basic Rent,
additional rent and other sums payable hereunder have been paid, and either
stating that to the knowledge of the signer of such certificate no default
exists hereunder or specifying each such default of which the signer has
knowledge. Any such certificate may be relied upon by the prospective mortgagee
or purchaser of requesting party's and Owner's interest in the Premises.

          (b)  PFM will, from time to time, upon 15 days' prior request by the
partnership, execute, acknowledge and deliver to the Partnership a certificate
of PFM stating that the Prime Lease is unmodified and in full effect (or, if
there have been modifications, that the Prime Lease is in full effect as
modified, and setting forth such modifications) and the dates to which Basic
Rent, additional rent and other sums payable thereunder have been paid, and
either stating that to the knowledge of the signer of such certificate no
default exists hereunder or specifying each such default of which the signer has
knowledge.  Any such certificate may be relied upon by the Partnership or any
prospective sublessee or assignee of the Partnership's interest in the Premises.
PFM hereby represents to the Partnership that as of the effective date of this
Sublease that (i) the Prime Lease is in full force and effect and unmodified,
(ii) all sums payable thereunder by PFM through the date hereof have been paid,
(iii) no notice of default has been received by PFM from Owner hereunder and
(iv) there are no facts or circumstances known to PFM which with the delivery of
notice or the passage of time or both, constitute a default

                                      -29-
<PAGE>

under the Prime Lease which have not been waived and consented to by Owner.

     21.  No Merger. There shall be no merger of this Sublease or of the
          ---------
leasehold estate hereby created with the fee estate in the Premises by reason of
the fact that the same person acquires or holds, directly or indirectly, this
Sublease or the leasehold estate hereby created or any interest herein or in
such leasehold estate as well as the fee estate in the Premises or any interest
in such fee estate.

     22.  Surrender.  Upon the expiration or termination of the term of this
          ---------
Sublease, the Partnership shall surrender the Premises to PFM in the condition
in which the Premises were originally received from PFM, except as repaired,
rebuilt, restored, altered or added to as permitted or required hereby, and
except for ordinary wear and tear.  The Partnership shall remove from the
Premises on or prior to such expiration or termination all property situated
thereon which is not owned by PFM, and shall repair any damage caused by such
removal. Property not so removed shall be deemed to be abandoned by the
Partnership and the Partnership's interests therein shall become the property of
PFM, and PFM may cause such property to be removed from the Premises and
disposed of, but the cost of any such removal and disposition and of repairing
any damage caused by such removal shall be borne by the Partnership.

     23.  Separability; Binding Effect.  Each provision hereby shall be separate
          ----------------------------
and independent and the breach of any such provision by PFM shall not discharge
or relieve the Partnership from its obligations to perform each and every
covenant to be performed by the Partnership hereunder.  If any provision hereof
or the application thereof to any person or circumstance shall to any extent be
invalid or unenforceable, the remaining provisions hereof, or

                                      -30-
<PAGE>

the application of such provision to persons or circumstances other than those
as to which it is valid or unenforceable, shall not be affected thereby, and
each provision hereof shall be valid and shall be enforceable to the extent
permitted by law. All provisions contained in this Sublease shall be binding
upon, inure to the benefit of, and be enforceable by, the respective successors
and assigns of PFM and the Partnership to the same extent as if each such
successor and assign were named as a party hereto. This Sublease may not be
changed, modified or discharged except by a writing signed by PFM and the
Partnership. This Sublease shall be governed by the laws of the state in which
the Premises are located.

     24.  Investment Tax Credit.  PFM agrees to elect, concurrently with the
          ---------------------
execution and delivery of this Sublease, in accordance with Section 48(d) of the
Internal Revenue Code and the regulations thereunder to treat the Partnership as
having acquired the New Improvements for an amount equal to its fair market
value so that the Partnership may obtain the benefit of the credit, if any,
allowable by Section 38 of the Internal Revenue Code with respect to the New
Improvements.  PFM shall not claim any such credit with respect to the New
Improvements.

     25.  Schedules.   Attached hereto are Schedules A, A-1, A-2, A-3, A-4, B
          ---------
and C referred to in this Sublease, which Schedules are hereby incorporated by

          ----------
shall execute and deliver a Memorandum of Sublease and Lease, making reference
to this instrument and in form suitable for recording in the public records of
Wood County, Ohio.

     27.  No Personal Liability. Unless and until Owner agrees to allow personal
          ---------------------
liability of PFM-EG as a partner of the Partnership, it is expressly agreed and
understood between PFM and the Partnership, anything in this Sublease to the
contrary notwithstanding, that any and all of the

                                      -31-
<PAGE>

covenants, undertakings and agreements herein made by the Partnership are not
made or intended as personal covenants, undertakings and agreements of the
individual partners of the Partnership, or their respective parent corporations,
but are made and intended for the purpose or with the intent of binding the
assets of the Partnership only, and no personal liability or responsibility is
assumed by or shall at any time be asserted or enforceable against the
individual partner of the Partnership, or their respective parent corporations
on account of this Sublease or on account of any covenants, undertakings or
agreements contained in this Sublease, either express or implied, and on account
of any judgments brought to enforce or determine such covenants, undertakings or
agreements, all such liability, if any. being expressly waived by PFM and by-
persons claiming by through or under PFM.

          IN WITNESS WHEREOF, PFM and the Partnership have each caused this
Sublease to be duly executed and delivered, all as of the date first above
written.
