     2.1  Construction Agent; Sale and Purchase.

     (a)  Pursuant to the Construction Agency Agreement, the
Owner Trustee is appointing the Construction Agent as its
construction agent with respect to the Units, and the
Construction Agent accepts such appointment pursuant to the
Construction Agency Agreement and hereto.  In its capacity as
such, the Construction Agent shall select, order, install (or
arrange for the installment of) and test the Units to be leased
by the Lessee, and shall take all necessary action to provide
that the Units will be In Service and subject to the Lease on or
prior to the Construction Termination Date.  If all of the Units
are not subject to the Lease for any reason (including, without
limitation, the failure of the Lessee to execute and deliver a
Lease Supplement with respect thereto, or if the conditions
precedent to the investment by the Participants pursuant to
Sections 4.3, 4.4, 4.5 and 4.8 have not been met) on or before
such Construction Termination Date, then the Construction Agent
shall pay, as damages, to the Owner Trustee on the day following
the Construction Termination Date, an amount equal to the sum of
(i) the outstanding principal amount of all Construction
Advances, plus (ii) the accrued and unpaid (and not previously
capitalized) interest on such Construction Advances as of the day
following the Construction Termination Date, plus (iii) the
accrued and unpaid Commitment Fee as of the day following the
Construction Termination Date, plus (iv) all other amounts due to
the Owner Trustee, the Owner Participant, the Construction
Lenders, the Indenture Trustee or any Indemnified Person pursuant
to this Agreement or any other Operative Agreement.  Upon receipt
of such payment, the Owner Trustee shall transfer all of the
Units to the Lessee (or as the Lessee may direct) and terminate
the Lease, without any representation or warranty, except as to
the absence of Lessor Liens.

     (b)  Subject to the terms and conditions hereof and on the
basis of the representations and warranties set forth herein, the
Owner Trustee agrees, on each Purchase Date, to purchase from the
vendor or manufacturer, or to make, or reimburse the Construction
Agent for, progress payments to the vendor or manufacturer of,
the Units described in the Purchase Notice given pursuant to
Section 2.3(a) with respect to such Purchase Date, and in
connection therewith, the Owner Trustee agrees to pay to the
vendor or manufacturer, or, in the case of a reimbursement, the
Construction Agent, the Purchase Cost or a progress payment for
each such Unit, or portion thereof, as specified in the Purchase
Notice relating to such Unit; provided, however, that the Owner
Trustee shall not be obligated to purchase on any Purchase Date
any Unit that is destroyed, damaged, defective, in unsuitable
condition or otherwise unacceptable to the Lessee for lease
pursuant to the Lease; and provided further, however, that the
principal amount of all advances made under the Interim Financing
Documents, and all accrued and unpaid interest and fees
thereunder, outstanding as of the Effective Date shall be rolled
over and deemed to have been advanced to the Owner Trustee as
Construction Advances (made pro rata by the Construction Lenders
in proportion to the respective Construction Commitment Amounts
of such Construction Lenders) on the Effective Date, such
Effective Date to be deemed to be a Purchase Date for all
purposes hereunder.

     (c)  During the period from the first  Purchase Date to the
Lease Term Commencement Date (the "Construction Term"), the
Construction Agent shall (i) at its expense, carry and maintain
insurance with respect to such Units as set forth in Section 12
of the Lease and (ii) keep such Unit at the site identified in
the Purchase Notice.  In the event that an Event of Loss shall
occur during the Construction Term, the Construction Agent shall,
on or before the earlier of the date that is 180 days after the
date of such Event of Loss and the Construction Termination Date,
either (i) replace such Unit with a replacement Unit meeting the
standards of Section 11.2(i) of the Lease or (ii) pay to the
Owner Trustee an amount equal to the outstanding Construction
Advances, together with all accrued and unpaid (and not
previously capitalized) interest thereon and all other amounts
due with respect thereto (including but not limited to the
accrued and unpaid Commitment Fee); provided that the
Construction Agent shall, not later than 60 days after the date
of such Event of Loss, notify the Owner Trustee and the
Construction Loan Agent of the action which it proposes to take
with respect to such Event of Loss.  The Construction Agent 
agrees that the Owner Trustee and the Construction Lenders shall
have all of the rights of inspection with respect to the Units
during the Construction Term therefor as set forth in Section 13
of the Lease.

     (d)  It is the intent of the Construction Agent, the Owner
Trustee and the Owner Participant that during the Construction
Term, each Unit purchased on a Purchase Date from a vendor or
manufacturer shall be owned by the Owner Trustee.  If any court
shall determine that any Unit is owned by the Construction Agent
during the Construction Term, the Construction Agent shall be
deemed to have granted and assigned, and hereby grants and
assigns, to the Owner Trustee during the Construction Term a
continuing, first priority security interest in and to such Unit
and the proceeds thereof, whether now owned or hereafter
acquired, and wherever located, as security for the Construction
Agent's obligations with respect to such Unit under the Operative
Agreements, including, without limitation, the Construction
Agent's obligations pursuant to Section 2.1(a).  The Construction
Agent hereby acknowledges that the Owner Trustee has pledged
during the Construction Term all of its right, title and interest
in the Units to the Construction Loan Agent, for the benefit of
the Construction Lenders, pursuant to the Construction Loan
Agreement.  The Construction Agent hereby agrees to take all such
action, at its expense, as the Owner Trustee, the Owner
Participant or the Construction Loan Agent may reasonably
request, including, without limitation, the execution, delivery
and filing of financing statements, in order to perfect the Owner
Trustee's or the Construction Loan Agent's interest in the Units
during the Construction Term or to otherwise carry out the intent
of this Agreement.

     2.2  Construction Advances.

     (a)  In order to finance the cost (including progress
payments) of the Units related to a Purchase Date, to pay
Transaction Costs described in Section 2.8(a)(i) through and
including (xiii) incurred prior to the Closing and to make
required interest payments, Section 2.1 of the Trust Agreement
authorizes the Owner Trustee, subject to the terms and conditions
hereof, to borrow funds from the Construction Lenders pursuant to
the Construction Loan Agreement and hereto (each such borrowing,
a "Construction Advance").  In no event shall the aggregate
principal amount of all Construction Advances outstanding exceed
the Construction Commitment Amount.  The Construction Advances
are to be made under, and secured by, the Construction Loan
Agreement.  The Construction Advances shall be LIBOR Advances;
interest shall be payable on the Construction Advances at the
rates and times set forth in the Construction Loan Agreement. 
The Construction Advances shall be repaid  in full on the earlier
to occur of the Lease Term Commencement Date and the day
immediately following the Construction Termination Date.

     (b)  Subject to the terms and conditions hereof (including,
without limitation, the second proviso to Section 2.1(b)) and on
the basis of the representations and warranties set forth herein,
on each Purchase Date, on each date that Transaction Costs are
payable and on each date that interest on a Construction Advance
is due (each of the foregoing, an "Advance Date"), in each case
that occurs on or prior to the Construction Termination Date, the
Construction Lenders will make a Construction Advance to the
Owner Trustee in an amount equal to (v) the Purchase Cost, or a
portion thereof, of the Units to be purchased by the Owner
Trustee on such Purchase Date, (w) progress payments upon any
Unit then due and owing, (x) the Transaction Costs described in
Section 2.8(a)(i) through and including (xiii) then due and
owing, (y) the accrued interest on the Construction Advances due
on such date, or (z)  the sum of any combination of the foregoing
clauses (v), (w), (x) or (y); provided, however, that the
commitment of the Construction Lenders to make Construction
Advances shall not exceed the excess of the Construction
Commitment Amount over the aggregate principal amount of all
Construction Advances then outstanding.

     (c)  If on any Advance Date the conditions to the
obligations of the Construction Lenders specified in Sections 4.1
and 4.2 have not been fulfilled or waived in writing by the
Construction Lenders, the Construction Lenders may thereupon
elect to be relieved of all further obligations under this
Agreement with respect to the transactions contemplated to occur
on such Advance Date.  Nothing in this paragraph shall operate to
relieve the Owner Trustee, the Owner Participant, the
Construction Agent or the Lessee from any of their respective
obligations hereunder or to waive the Construction Loan Agent's
or the Construction Lenders' rights against the Owner Trustee,
the Owner Participant or the Lessee.

     2.3  Purchase Dates; Advance Dates; Procedure for Funding.

     (a)  Notice of Purchase Date.  The purchase of Units
pursuant to Section 2.3 (b), the making of progress payments and
the making of the related Construction Advance shall take place
on any Business Day occurring on or before the Construction
Termination Date (each a "Purchase Date"), provided that (i)
there shall be no more than two Purchase Dates in any calendar
month, (ii) the aggregate Purchase Cost of the Units to be
purchased on each Purchase Date and progress payments to be made
on each Purchase Date shall not be less than $100,000 and (iii)
the Construction Agent shall have delivered written notice of
such Purchase Date (each such notice, a "Purchase Notice") to the
Owner Trustee, the Owner Participant and the Construction Loan
Agent at least two Business Days prior to such proposed Purchase
Date.  Each Purchase Notice shall be in the form attached hereto
as Exhibit P, appropriately completed.  Prior to 12:00 noon, New
York City time, on such Purchase Date, subject to the fulfillment
of the applicable conditions precedent set forth herein, each
Construction Lender shall make its Construction Percentage of the
amount of the Construction Advance required to be paid on such
Purchase Date available to the Owner Trustee, by transferring or
delivering such amount, in funds immediately available on such
Purchase Date, to the Owner Trustee, either directly to, or for
deposit in, the Owner Trustee's account number 55-05-300-4673100
at Boatmen's First National Bank of Amarillo (ABA No. 111-300-
945), account name: Credit Trust Account, with a reference to
EDNC Trust-1997.  The making available by the Construction
Lenders of the Construction Advance to be paid on such Purchase
Date shall be deemed a waiver by the Construction Lenders of the
timely delivery of the Purchase Notice (if not theretofore
delivered on a timely basis).

     (b)  Purchase.  With respect to each Purchase Date, upon
receipt by the Owner Trustee on such Purchase Date of the
Construction Advance required to be paid on such Purchase Date,
the Owner Trustee shall, subject to the conditions set forth in
Sections 4.1 and 4.2 having been fulfilled to the satisfaction of
the Owner Participant and the Construction Loan Agent or waived
by the Owner Participant and the Construction Loan Agent, pay to
the applicable sellers of the Units or make progress payments in
respect of Units (or reimburse the Construction Agent for
payments made to the applicable sellers) from the proceeds of
Construction Advances, in immediately available funds, an amount
equal to the Purchase Cost, or a portion thereof, for the Units
to be settled for on such Purchase Date or with respect to which
progress payments are being made, as set forth in the related
Purchase Notice.

     (c)  Advance Date Notice.  Two Business Days prior to each
Advance Date, the Construction Agent shall deliver to the Owner
Trustee, the Owner Participant and the Construction Loan Agent a
notice substantially in the form of Exhibit Q (each, an "Advance
Date Notice"), appropriately completed.  

     (d)  Construction Advances.  Prior to 12:00 noon, New York
City time, on such Purchase Date, subject to the fulfillment of
the applicable conditions precedent set forth herein, each
Construction Lender shall make its Construction Percentage of the
amount of the Construction Advance required to be paid on such
Purchase Date available to the Owner Trustee, by transferring or
delivering such amount, in funds immediately available on such
Purchase Date, to the Owner Trustee, either directly to, or for
deposit in, the Owner Trustee's account number 55-05-300-4673100
at Boatmen's First National Bank of Amarillo  (ABA No. 111-300-
945), account name: Credit Trust Account, with a reference to
EDNC Trust-1997.  The making available by the Construction
Lenders of the Construction Advance to be paid on such Purchase
Date shall be deemed a waiver by the Construction Lenders of the
timely delivery of the Purchase Notice (if not theretofore
delivered on a timely basis).

     (e)  Interest Periods.  On each Advance Date, the Lessee
shall specify the Interest Period applicable to the related
Construction Advance as set forth in the Advance Date Notice
related thereto.  On the last day of each Interest Period for a
LIBOR Advance, the Lessee shall continue such Construction
Advance, in whole, as a LIBOR Advance for a subsequent Interest
Period with a duration as set forth in the applicable Advance
Date Notice.  Any such Construction Advances pursuant to Section
2.3(d) shall be subject to the following: 

          (i)  each LIBOR Advance shall be in a principal amount
     equal to at least $100,000;

          (ii) there shall not be more than three (3) different
     Interest Periods outstanding at any one time; and

          (iii) no Interest Period shall extend beyond the
     Scheduled Lease Commencement Date.

Each Purchase Notice and Advance Date Notice shall be
irrevocable.  If no notice is given with respect to the
continuation of a LIBOR Advance on or prior to the second
Business Day before the last day of the Interest Period with
respect thereto, such Construction Advance shall have an Interest
Period of one month. 

     2.4  Investments by the Owner Participant.

     (a)  Subject to the terms and conditions hereof and on the
basis of the representations and warranties set forth herein, on
the Lease Term Commencement Date, the Owner Participant agrees to
participate in the payment of the Total Equipment Cost for all of
the Units, taken together as a whole, by making an equity
investment in the beneficial ownership of such Units in the
amount (the Owner Participant's "Commitment") equal to the Owner
Participant's Percentage of the Total Equipment Cost for all of
the Units.  The Owner Participant's Commitment shall be paid to
the Owner Trustee to be held and applied by the Owner Trustee
toward the repayment of the Construction Advances then
outstanding made by Security Pacific and as provided in Section
2.6.  In no event shall the aggregate amount of (x) the Owner
Participant's Percentage of the Total Equipment Cost and (y) the
Transaction Costs (which the Owner Participant shall pay pursuant
to Section 2.8(a)) exceed $15,000,000.  

     (b)  If on the Lease Term Commencement Date the conditions
to the obligations of the Owner Participant specified in Sections
4.3, 4.4 and 4.8 have not been fulfilled or waived by it, the
Owner Participant may thereupon elect to be relieved of all
further obligations under this Agreement with respect to the
transactions contemplated to occur on the Lease Term Commencement
Date.  In case any Note Purchaser shall default in its obligation
to make the amount of its commitment available pursuant to
Section 2.5 on the Lease Term Commencement Date, the Owner
Participant shall use its reasonable efforts to promptly find a
replacement Note Purchaser (but shall not be required to find,
nor to fund itself as, a replacement Note Purchaser).  Nothing in
this paragraph shall operate to relieve the Lessee, the Owner
Trustee, the Indenture Trustee or the Note Purchaser from any of
their respective obligations hereunder or to waive any of the
Owner Participant's rights against the Lessee, the Owner Trustee,
the Indenture Trustee or the Note Purchaser.

     2.5  Issue and Sale of Note.

     (a)  In order to finance a portion of the Total Equipment
Cost of all of the Units, Section 2.1 of the Trust Agreement
authorizes the Owner Trustee, subject to the terms and conditions
hereof, to issue and sell secured notes of one series.  In no
event shall the aggregate principal amount of the Note exceed the
lesser of (i) 85% of the Total Equipment Cost and (ii)
$65,000,000.  The Note is to be issued under, and secured by, the
Indenture.  The Note is to be dated the date of original issue,
to bear interest prior to maturity at the rate designated in such
Note, payable monthly on each Rent Payment Date for the related
Lease Supplement thereafter until and including maturity, and to
be otherwise in the form of Note attached to the Indenture as
Exhibit A.  The term  Note  or  Notes , as used herein and in the
other Operative Agreements, shall mean and include the Note
issued under the Indenture and any Notes issued in exchange
therefor or replacement thereof pursuant to the Indenture.

     (b)  Subject to the terms and conditions hereof and on the
basis of the representations and warranties set forth herein, on
the Lease Term Commencement Date, the Note Purchaser will
participate in the payment of the Total Equipment Cost for all of
the Units by purchasing the Note at a price in United States
dollars equal to 100% of the principal amount thereof and in an
aggregate principal amount equal to the product of (i) the Total
Equipment Cost for all of the Units and (ii) the percentage set
forth therefor in the Owner Participant's Certificate described
in Section 2.6(a); provided that the commitment of the Note
Purchaser to purchase its Note pursuant to this Section 2.5(b)
shall not exceed the amount set forth on Schedule 10 hereto; and
provided, further, that the aggregate principal amount of the
Note to be issued on the Lease Term Commencement Date to the Note
Purchaser shall be equal to the product of (x) the percentage set
forth for such Note Purchaser on Schedule 10 hereto and (y) the
aggregate principal amount of the Note to be issued on the Lease
Term Commencement Date.  Notwithstanding the foregoing, the Note
Purchaser shall be deemed to have purchased its Note and to have
repaid the Construction Advances (except any portion thereof
attributable to Transaction Costs, but excluding (i) accrued and
unpaid interest on such Transaction Costs and (ii) previously
capitalized interest on such Transaction Costs (such portion
attributable to Transaction Costs, after giving effect to the
exclusions in the immediately preceding clauses (i) and (ii),
being  Excluded Transaction Costs )) then outstanding made by
such Note Purchaser in its capacity as a Construction Lender,
together with all accrued but unpaid interest on such
Construction Advances, on the Lease Term Commencement Date
without any further action required by such Note Purchaser;
provided, however, that if the amount set forth in clause (A) of
the fourth sentence of Section 2.6(a) (the  Clause (A) Amount )
is other than the outstanding principal amount of, and accrued
and unpaid (and not previously capitalized) interest payable to
Security Pacific upon, Construction Advances of Security Pacific,
other than that portion of Excluded Transaction Costs which are a
part thereof (the "Security Pacific Amount"), then (x) if such
Clause A Amount is greater than the Security Pacific Amount, the
Owner Trustee, following receipt of the Clause A Amount from the
Owner Participant upon the consummation of the Closing, shall
apply the sum which shall be equal to the difference between the
Clause A Amount and the Security Pacific Amount to the
outstanding principal amount of, and accrued and unpaid (and not
previously capitalized) interest payable to the Construction
Lenders other than Security Pacific upon, Construction Advances
of Construction Lenders other than Security Pacific, other than
that portion of Excluded Transaction Costs which are a part
thereof, and (y) if the Clause A Amount is less than the Security
Pacific Amount, the participation of the Note Purchaser
determined pursuant to the provisions of this Section 2.5(b),
except for this sentence, shall be paid to Security Pacific as a
Construction Lender upon the consummation of the Closing, so that
in the case of each of the foregoing clauses (x) and (y) Security
Pacific and each other Construction Lender shall be paid its
outstanding principal amount of, and accrued and unpaid (and not
previously capitalized) interest upon, its Construction Advances,
other than that portion of Excluded Transaction Costs which are a
part thereof, in full.  The Note delivered to the Note Purchaser
will be typewritten and will be in the form of a single Note
registered in the name of such Note Purchaser.  Contemporaneously
therewith, Excluded Transaction Costs will be paid by the Owner
Participant to the Owner Trustee pursuant to Section 2.8(a) and
will be applied by the Owner Trustee to the Construction Advances
so that upon the payment thereof and consummation of the Closing
the aggregate outstanding principal amount of, and accrued and
unpaid (and not previously capitalized), interest payable to the
Construction Lenders upon, the Construction Advances shall be
paid in full.

     (c)  If on the Lease Term Commencement Date the conditions
to the obligations of the Note Purchaser specified in Sections
4.3, 4.5 and 4.8 have not been fulfilled or waived by the Note
Purchaser, the Note Purchaser may thereupon elect to be relieved
of all further obligations under this Agreement with respect to
the transactions contemplated to occur on the Lease Term
Commencement Date.  In such an event, the Owner Trustee shall
immediately pay to the Construction Lenders an amount equal to
the sum of (i) the outstanding principal amount of all
Construction Advances, plus (ii) the accrued and unpaid interest
on such Construction Advances as of the Construction Termination
Date, plus (iii) the accrued and unpaid Commitment Fee, plus (iv)
all other amounts due to the Construction Lenders pursuant to
this Agreement or any other Operative Agreement.   In case the
Owner Participant shall default in its obligation to make the
amount of its Commitment available pursuant to Section 2.4, or to
make the amount of the Excluded Transaction Costs available
pursuant to Section 2.8(a), the Note Purchaser shall have no
obligation to make any amounts available under any Operative
Agreement.  Nothing in this paragraph shall operate to relieve
the Owner Trustee, the Owner Participant, the Lessee or the
Indenture Trustee from any of their respective obligations
hereunder or to waive any Note Purchaser's rights against the
Owner Trustee, the Owner Participant, the Lessee or the Indenture
Trustee.

     2.6  Lease Term Commencement Date; Procedure for
          Participation

     (a)  Notice of Closing.  The refinancing and lease of all of
the Units, taken together as a whole,  and purchase by the Note
Purchaser of the Note shall take place, and all documentation
relating thereto shall be delivered, at the offices of Mayer,
Brown & Platt, 1675 Broadway, New York, New York 10019-5820
commencing at 10:00 a.m., New York City time, on the Lease Term
Commencement Date designated by not less than five Business Days'
(or such lesser notice agreed upon by the Lessee, the Owner
Participant and the Note Purchaser) prior written notice by the
Lessee to the Owner Participant, the Owner Trustee, the Indenture
Trustee and the Note Purchaser (such notice being referred to as
a "Notice of Lease Commencement"); provided, however that (i)
there shall not be more than one Lease Term Commencement Date,
(ii) the Lessee shall use its reasonable efforts to effect the
Lease Term Commencement Date on the first day of a calendar month
and (iii) the Lease Term Commencement Date shall occur on or
before June 30, 1999.  The aforesaid closing is referred to as
the  Closing.  The Notice of Lease Commencement shall be by
facsimile transmission promptly confirmed by telephone and shall
specify in reasonable detail (i) the number, type and description
of all of the Units, (ii) the Total Equipment Cost of such Units,
(iii) the Equipment Cost of each Unit, (iv) the proposed Lease
Term Commencement Date and (v) the location of such Units (if
other than at the Premises).  Not less than two Business Days
prior to the Lease Term Commencement Date, the Owner Participant
shall deliver to the Lessee, the Owner Trustee, the Indenture
Trustee and the Note Purchaser a certificate (the  Owner
Participant's Certificate ) setting forth (A) the amount of the
Owner Participant's Commitment (to be paid on the Lease Term
Commencement Date), (B) the Owner Participant's Percentage of the
Total Equipment Cost (to be funded on the Lease Term Commencement
Date), (C) the aggregate principal amount of the Note to be sold
on such Lease Term Commencement Date and purchased by the Note
Purchaser, and (D) the percentage of the Total Equipment Cost for
all of the Units to be funded by the Note Purchaser on the Lease
Term Commencement Date through the purchase of the Note, and
having attached thereto revised Schedules 2, 3, 4 and 5 to this
Participation Agreement (as the same relate to the Lease Term
Commencement Date) reflecting any adjustments to Basic Rent,
Stipulated Loss Value, Termination Value and debt amortization
pursuant to Section 2.9(a)(i).  Nothing in this Section 2.6(a)
shall limit or affect the Owner Participant's right to make post-
closing adjustments pursuant to Section 2.9(a).  Prior to 12:00
noon, New York City time, on the Lease Term Commencement Date,
the Owner Participant shall make the amount of the Owner
Participant's Commitment, and, subject to the second sentence of
Section 2.5(b), the Note Purchaser shall make the principal
amount of the Note to be purchased on the Lease Term Commencement
Date, available to the Owner Trustee, by transferring or
delivering such amounts, in funds immediately available on the
Lease Term Commencement Date, to the Owner Trustee, either
directly to, or for deposit in, the Owner Trustee's account
number 55-05-300-4673100 at Boatmen's First National Bank of
Amarillo (ABA No. 111-300-945), account name: Credit Trust
Account, with a reference to EDNC Trust-1997.  The making
available by the Owner Participant of its Commitment on the Lease
Term Commencement Date (which may include the tendering by the
Owner Participant of its interest in the Construction Note) shall
be deemed a waiver by the Owner Participant and the Owner
Trustee, and the making available by the Note Purchaser of the
funds to be paid by such Note Purchaser on the Lease Term
Commencement Date (which may include the tendering by the Note
Purchaser of its interest in the Construction Note) shall be
deemed a waiver by such Note Purchaser and the Indenture Trustee,
of the timely delivery of the Notice of Lease Commencement (if
not theretofore delivered on a timely basis).   

     (b)  Closing.  With respect to the Lease Term Commencement
Date, upon receipt (or deemed receipt) by the Owner Trustee on
the Lease Term Commencement Date of the Owner Participant's
Commitment (required to be paid on the Lease Term Commencement
Date), the proceeds (or deemed proceeds) of the Note to be sold
on the Lease Term Commencement Date, and the Excluded Transaction
Costs, the Owner Trustee shall, subject to the conditions set
forth in Sections 4.3, 4.4 and 4.8 having been fulfilled to the
satisfaction of the Owner Participant or waived by the Owner
Participant and subject to the conditions set forth in Sections
4.3, 4.5 and 4.8 having been fulfilled to the satisfaction of the
Note Purchaser or waived by the Note Purchaser, pay (and to the
extent of deemed proceeds be deemed to have paid) to the
Construction Loan Agent, for the benefit of the Construction
Lenders, from the funds then held by it, in immediately available
funds, an amount equal to the outstanding Construction Advances,
plus all accrued and unpaid (and not previously capitalized)
interest thereon.

     (c)  Failure to Close.  If on the Lease Term Commencement
Date the Owner Participant fails to make any payment required of
it under this Section 2.6, a Note Purchaser fails to purchase its
Note or the Owner Participant, a Note Purchaser or the
Construction Agent otherwise is in breach of any of its material
obligations under any Operative Agreement, then any party hereto
(other than the party so failing to make the payment (other than
by reason of a failure of the closing conditions contained herein
to be satisfied) or otherwise in breach) may cancel its
obligations under this Agreement with respect to the Closing and
the transactions contemplated hereby with respect to the Closing
by notice to the other parties; provided that this Section 2.6(c)
shall neither limit the obligations, if any, of the Construction
Agent under Section 2.8(c), and such obligations shall survive
any exercise of rights by the Construction Agent, nor affect any
rights any non-breaching party hereto may have against either the
Owner Participant or a Note Purchaser for any failure described
in this Section 2.6(c); and provided further, with respect to any
funds actually deposited by a Participant with the Owner Trustee
as payment under Sections 2.4 and 2.5 and this Section 2.6,
interest shall be paid in the same manner, and to the same
extent, as provided for in Section 2.10(b) mutatis mutandis if
such Participant is not the party in breach.

     (d)  Transfer of Rights.  For and in consideration of the
payment of the Construction Advances and other amounts payable
hereunder, and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the
Construction Agent shall convey, assign, bargain, grant, transfer
and sell to the Owner Trustee, and its successors and assigns, if
not theretofore conveyed, assigned, bargained, granted,
transferred and sold to the Owner Trustee, all of the
Construction Agent's right, title and interest, if any, in each
Unit on and as of the Lease Term Commencement Date, free and
clear of all Liens, other than Permitted Liens.  The Construction
Agent covenants and agrees that it will defend the Owner
Trustee's title to each Unit against the claims and demands of
all persons whomsoever.

     2.7  Owner Participant's Instructions.

     (a)  Authorization and Direction on the Lease Term
Commencement Date.  The Owner Participant agrees that its making
available to the Owner Trustee the amount of its Commitment for
the Units and an amount equal to the Excluded Transaction Costs
in accordance with the terms of this Section 2 shall constitute,
without further act, authorization or direction by the Owner
Participant to the Owner Trustee, subject, on the Lease Term
Commencement Date, to the conditions set forth in Sections 4.3,
4.4 and 4.8 having been fulfilled to the satisfaction of the
Owner Participant or waived by the Owner Participant, to take the
actions specified in Section 2.1 of the Trust Agreement with
respect to all of the Units, taken together as a whole,  on the
Lease Term Commencement Date.  The Owner Participant further
agrees that the authorization by the Owner Participant to the
Owner Trustee to release to the Construction Loan Agent, for the
benefit of the Construction Lenders, the Owner Participant's
Commitment and Excluded Transaction Costs shall constitute,
without further act, notice and confirmation that all conditions
to such closing set forth in Sections 4.3, 4.4 and 4.8 were
either met to the satisfaction of the Owner Participant or, if
not so met, were waived as a condition precedent to such closing
by it.

     (b)  Authorization and Direction Regarding Replacement
Units.  The Owner Participant agrees, in the case of any
Replacement Unit substituted pursuant to Section 11.4 of the
Lease, that the Owner Trustee is authorized and directed to take
the actions specified in such Section 11.4 of the Lease with
respect to such Replacement Unit upon due compliance by the
Lessee with the terms and conditions set forth in such Section of
the Lease with respect to such Replacement Unit.

     2.8  Expenses.

made its equity investment provided for in Section 2.4 and the

of doubt, shall include the accrued and unpaid Commitment Fee),

The foregoing agreement to pay Transaction Costs is in addition

Owner Participant shall not be obligated to pay any Transaction

after the Lease Term Commencement Date.

    (b)  Other Expenses  After the consummation of the

Purchase Date or the Lease Term Commencement Date are not
consummated for any reason, the Construction Agent shall pay all

satisfied or waived by it in writing, the Owner Participant shall

its own fees and expenses and the fees and expenses of its
special counsel, Mayer, Brown & Platt; or (ii) the Note
Purchaser's failure to purchase the Note as required by Section

    2.9  Calculation of Adjustments to Basic Rent, Stipulated
         Loss Value, Termination Value and Note Amortization;
         Confirmation and Verification.                          
         

    (a)  Calculation of Adjustments.  

         (i)    In the event that, with respect to the Units: 
    (A) there is any variation from the Pricing Assumptions set
    forth on Schedule 8 (other than the application of Section
    168(d)(3) of the Code), (B) a Change in Tax Law occurs, or
    (C) a Proposed Change in Tax Law is finalized or enacted, as
    applicable; then, subject to Section 2.9(c), in each such
    case, the Owner Participant shall recalculate (and adjust
    upward or downward, as appropriate) the payments or amounts,
    as the case may be, of Basic Rent, Stipulated Loss Values
    and Termination Values and, solely upon written direction
    from the Lessee, and subject to the satisfaction of the
    conditions contained in Section 2.9(d) and in accordance
    with the procedures set forth in Section 2.14 of the
    Indenture, the amortization of the Notes, in each case for
    or with respect to such Units (x) first to preserve the Net
    Economic Return that the Owner Participant would have
    realized had the events described in the foregoing clauses
    (A) through (C) not occurred, and (y) then to minimize to
    the greatest extent possible, consistent with the
    requirements set forth in this Section 2.9(a)(i), the
    present value (discounted quarterly at an interest rate per
    annum equal to the applicable Debt Rate) of the payments of
    Basic Rent for such Units, taken together as a whole.  In
    the case of the events described in clause (A) of the
    immediately preceding sentence actually known to the Lessor
    at least five (5) Business Days prior to the Lease Term
    Commencement Date, Lessor shall prepare adjustments (upward
    or downward) no later than three (3) Business Days prior to
    the Lease Term Commencement Date.  In the case of the events
    described in clauses (A) or (B) of the immediately preceding
    sentence, such adjustments shall be made on or prior to, and
    shall be effective as of the Lease Term Commencement Date;
    in the case of the events described in clause (C) of such
    sentence, such adjustments shall be effective as of the next
    Rent Payment Date which is at least 30 days after the event
    giving rise to such adjustment.  In performing any such
    recalculation and in determining the preservation of the
    Owner Participant's Net Economic Return, the Owner
    Participant shall utilize the same methods and assumptions
    as are set forth in the definition of Net Economic Return
    (other than those assumptions which changed as a result of
    any of the events described in clauses (A) through (C) of
    the first sentence of this paragraph (i) necessitating such
    recalculation).  Such adjustments shall comply with:  (1)
    Section 467 of the Code (including regulations, rulings and
    decisions if any, issued under, or with respect to, Section
    467 of the Code prior to such adjustment and applicable
    thereto) such that no such adjustment shall cause the Lease
    to be a disqualified leaseback within the meaning of such
    Code section, (2) Revenue Procedures 75-21 and 75-28
    Sections 4.02(5), 4.07(1) and 4.08(1) (except as applicable
    to uneven payments of rent), and (3) to the extent possible,
    while still preserving the Owner Participant's Net Economic
    Return and meeting the other requirements of this Section
    2.9(a), the requirements of FASB Statement No. 13 in order
    that the Lease will qualify as an operating lease
    thereunder.  Each adjustment shall be reflected in an
    appropriate adjustment of the appropriate portions of
    Schedules 2, 3, 4 and/or 5 and/or 7 to this Agreement (and
    the related adjustments to the assumptions contained in
    clauses (A) through (C) above).

         (ii)   The adjustments to the Schedules referred to in
    paragraph (i) above shall be made, subject always to
    Sections 2.9(b) and 2.9(c), by the Owner Participant without
    the consent of the other parties hereto.

    (b)  Confirmation and Verification.  Upon completion of any
recalculation with respect to the Units described above in
Section 2.9(a), a duly authorized officer of the Owner
Participant shall provide a certificate to the Lessee, the
Indenture Trustee and each holder of a Note either (x) stating
that for such Units the payments of Basic Rent, Stipulated Loss
Values, Termination Values and amortization of the Notes with
respect to the Lease Term as are then set forth in the
appropriate portions of Schedules 2, 3, 4 and 5 of this Agreement
do not require change, or (y) setting forth such adjustments to
such payments of Basic Rent, Stipulated Loss Values, Termination
Values or amortization of the Notes with respect to the Lease
Term as have been calculated by the Owner Participant in
accordance with Section 2.9(a) above.  Such certificate shall
describe in reasonable detail the basis for any such adjustments. 
If the Lessee shall so request within 30 days of receiving the
certificate described in the first sentence of this Section
2.9(b), the recalculation of any such adjustments described in
this Section 2.9 shall be verified by a nationally recognized
firm of certified public accountants (other than the firm which
then prepares the Lessee's audited statements unless the Owner
Participant otherwise consents, which consent may be withheld in
the Owner Participant's sole and absolute discretion) selected by
the Lessee and reasonably acceptable to the Owner Participant,
and any such recalculation of such adjustment as so verified
shall be binding on the Lessee and the Owner Participant.  Such
accountants shall be requested to make their determination within
30 days of its appointment by the Lessee.  The Owner Participant
shall provide to a representative of such accountants, on a
confidential basis (and such accountants shall be obligated to
execute a confidentiality agreement in form and substance
reasonably acceptable to the Owner Participant), the original
assumptions used by the Owner Participant and the methods used by
the Owner Participant in the original calculation of, and any
recalculation of, Basic Rent, Stipulated Loss Values, Termination
Values and amortization of the Notes and such other information
as is necessary to determine whether the computation is accurate
and in conformity with the provisions of this Agreement.  In no
event shall the Owner Participant be required to provide any tax
return in connection with any verification.  All materials
provided by the Owner Participant shall remain the property of
the Owner Participant and shall be returned to the Owner
Participant contemporaneously with the completion of the
verification process.  The costs of such verification shall be
borne by the Lessee, except that if such accounting firm s
verification shall result in a decrease in the net present value
of Basic Rent, as compared to the net present value of Basic Rent
proposed by the Owner Participant, each discounted at the
applicable Debt Rate, by more than 15 basis points, then the
Owner Participant shall pay the costs of such verification.  

    (c)  Sufficiency of Rent, etc.; Compliance of Adjustments. 
Anything contained in this Section 2.9 to the contrary
notwithstanding, any adjustment made to the payments of Basic
Rent, Stipulated Loss Values or Termination Values with respect
to the Lease Term, pursuant to the foregoing, shall comply with
the following requirements:  (i) each installment of Basic Rent,
on the Lease Term Commencement Date and as adjusted pursuant to
this Section 2.9, under any circumstances and in any event, will
be in a scheduled amount at least sufficient for the Owner
Trustee to pay in full as of the due date of such installment any
scheduled payment of principal of and interest on the Notes
required to be paid on such due date of such installment of Basic
Rent, and (ii) Stipulated Loss Values and Termination Values, on
the Lease Term Commencement Date and as adjusted pursuant to this
Section 2.9, under any circumstances and in any event (assuming
there has been performance in full of the Lease), will be in a
scheduled amount at least sufficient to pay in full as of the
date of scheduled payment thereof, together with any installment
of Basic Rent, payable in arrears, scheduled to be payable as of
the date of scheduled payment thereof, the aggregate unpaid
principal of and all unpaid interest on the Notes accrued to the
date on which Stipulated Loss Value or Termination Value, as the
case may be, is to be paid in accordance with the terms of the
Lease.

    (d)  Adjustment Due to Change in Transaction Costs or Change
in Tax Rate.  If the Transaction Costs are other than 4.0% of
Total Equipment Cost, the principal amortization schedule for the
Notes may be modified by the Owner Participant, in accordance
with the procedure set forth in Section 2.14 of the Indenture;
provided, however, that (A) no such modification shall (1) change
the unpaid principal amount of any Outstanding Note or (2) extend
the Maturity Date of any Note, (B) after taking such modification
into account, the average life to maturity of such Notes shall
not be different by more than 180 days from the average life to
maturity of the Notes set out in Schedule 5 at the date hereof
and (C) any such adjustment resulting from a change in the
assumed Transaction Costs shall occur no later than six months
from the Lease Term Commencement Date.  In addition, Basic Rent,
Stipulated Loss Values and Termination Values with respect to the
Units may be adjusted due to such Change in Tax Rate so long as
Owner Participant holds Lessee harmless, on a net after-tax
basis, from any out-of-pocket expenses attributable to such
adjustment and any adverse tax effect of such adjustment, or
Owner Participant s payment of such expenses and such adjustment
(i) shall comply with Section 2.9(c), (ii) shall not (x) increase
the present value (discounted monthly at an interest rate per
annum equal to the applicable Debt Rate) of the payments of Basic
Rent and (y) as of any date, increase the sum of the present
value (discounted monthly at an interest rate per annum equal to
the applicable Debt Rate) of the payments of Basic Rent through
such date plus the present value (discounted monthly at an
interest rate per equal to the applicable Debt Rate) of the
Stipulated Loss Value or Termination Value as of such date, and
(iii) if the Lease qualified as an operating lease under FASB
Statement No. 13 prior to such adjustment, shall be made in such
a way so as to continue to comply with the requirements of FASB
Statement No. 13.

    2.10 Postponement of Closing; Termination of Transaction;
         and Expiration of Commitment.                           
                                                                 
                  

    (a)  Postponement.  The scheduled Closing may be postponed
from time to time for any reason (but to no later than the
Scheduled Lease Commencement Date subject to Section 2.6(a)) if
the Lessee gives the Participants and the Trustees facsimile
notice (promptly confirmed by telephone) of the postponement and
notice of the date to which such Closing has been postponed, the
notice of postponement to be received by each party no later than
11:00 a.m., New York City time, on the Scheduled Lease
Commencement Date, and the term  Scheduled Lease Commencement
Date  as used in this Agreement thereupon shall mean such
postponed  Scheduled Lease Commencement Date .

    (b)  Interest on Participant Funds.  In the event of any
postponement of the Scheduled Original Lease Commencement Date
pursuant to Section 2.10(a) or if the Lease Term Commencement
Date fails to occur:  (i) the Lessee will reimburse each
Participant for the loss of the use of its funds (other than
funds which are Construction Advances plus accrued and unpaid
(and not previously capitalized) interest thereon) occasioned by
such postponement by paying to such Participant on demand
interest at a rate per annum equal to the Debt Rate, for the
period from and including the Scheduled Original Lease
Commencement Date, if such Participant has made its funds
available, to but excluding the earlier of the date upon which
such funds are returned (unless such funds are returned after
1:00 p.m. (New York City time) in which case such date of return
shall be included) or the Lease Term Commencement Date; provided
that the Lessee shall in any event pay to each Participant at
least one day's interest on the amount of such funds, unless such
Participant shall have received, prior to 1:00 p.m. (New York
City time) on the Business Day preceding the Scheduled Original
Lease Commencement Date, a notice of postponement of the
Scheduled Original Lease Commencement Date pursuant to Section
2.10(a); and (ii) the Owner Trustee will return not later than
1:00 p.m. (New York City time), on the first Business Day
following the Scheduled Original Lease Commencement Date, any
such funds which it shall have received from such Participant and
originally expected to have been used in the Closing on the
Scheduled Original Lease Commencement Date.  Any Excluded
Transaction Costs which the Owner Participant has made available
shall be treated as a part of the funds subject to this Section
2.10(b).

    (c)  Expiration of Commitment.  Notwithstanding the
provisions of Section 2.10(a) or any other provision hereof,
neither the Owner Participant nor any Note Purchaser shall be
under any obligation to make its funds available beyond 1:00
p.m., New York City time, on June 30, 1999.  

    (d)  Several Commitments.  The obligations hereunder of the
Participants shall be several and not joint and no Participant
shall be liable or responsible for the acts or defaults of any
other Participant.

    2.11 Sufficiency of Note and Cash Payment.  Notwithstanding
anything to the contrary contained in this Agreement, the
aggregate of (i) the principal amount of the Note which
Bayerische shall receive on the Lease Term Commencement Date and
(ii) any cash payment which Bayerische shall receive from the
Owner Trustee on the Lease Term Commencement Date (such aggregate
of (i) and (ii), the  Aggregate Lease Term Commencement Date
Payment ) shall be not less than the aggregate of (x) the portion
of the accrued and unpaid Commitment Fee payable to Bayerische in
its capacity as a Construction Lender, and (y) the aggregate
outstanding principal amount of, and accrued and unpaid (and not
previously capitalized) interest payable upon, the Construction
Advances made by Bayerische in its capacity as a Construction
Lender. The Construction Loan Agent s calculation with respect to
whether the Aggregate Lease Term Commencement Date Payment is
sufficient in terms of the foregoing sentence shall control
absent demonstrable error.

    the laws of the State of its incorporation, and has the
    corporate power and authority to conduct its business as now
    conducted, to own or hold under lease its properties and to
    execute, deliver and perform its obligations under the
    Operative Agreements to which it is or is to become a party. 
    The Lessee is duly qualified to do business and is in good
    standing in: (i) each jurisdiction in which Units to be
    leased by the Lessee are located; and (ii) each other
    jurisdiction in which its business is conducted, except
    where failure so to qualify or to be in good standing could
    not reasonably be expected to have a Material Adverse
    Effect.

         (b)    Due Authorization; No Conflict.  Each of the
    Operative Agreements to which the Lessee is or is to become
    a party has been duly authorized by all necessary corporate
    action on the part of the Lessee and has been or on each
    Purchase Date or Lease Term Commencement Date, as the case
    may be, will have been, duly executed and delivered by the
    Lessee, and the execution, delivery and performance thereof
    and compliance by the Lessee with all of the provisions
    hereof and thereof do not, and on each Purchase Date and the
    Lease Term Commencement Date will not (i) require any
    approval of the shareholders of the Lessee or any approval
    or consent of any trustee or holder of any indebtedness or
    obligation of the Lessee, other than such consents and

    other agreement or instrument to which the Lessee is a party
    or by which the Lessee or any of its properties is bound.
    The Lessee is in compliance with all applicable laws,
    including Environmental Laws and Governmental Actions, the
    failure to comply with which could reasonably be expected to
    have a Material Adverse Effect.

         (c)    Governmental Action.  All Governmental Action,
    required in connection with the execution, delivery and
    performance by the Lessee of the Operative Agreements to
    which it is or is to become a party, has been or will have
    been on each Advance Date and the Lease Term Commencement
    Date obtained, given or made (and are or will be in full
    force and effect), but for those Governmental Actions, all
    of which are either (x) not required on the date hereof or
    on the related Advance Date or the Lease Term Commencement
    Date, as the case may be, and cannot be obtained prior to
    such date(s), as the case may be, or (y) for which the
    failure to obtain, give or make could not reasonably be
    expected to have a Material Adverse Effect.

         (d)    Enforceability.  Each of the Operative
    Agreements to which the Lessee is or is to become a party
    constitutes, or, when executed and delivered by the Lessee,
    will constitute, the legal, valid and binding obligation of
    the Lessee, enforceable against the Lessee in accordance
    with the terms thereof, except as enforceability may be
    limited by bankruptcy, insolvency, reorganization,
    moratorium or other laws affecting the enforcement of
    creditors', mortgagees' or lessors' rights in general and by
    general principles of equity (regardless of whether such
    enforceability is considered in a proceeding in equity or at
    law).

         (e)    Litigation. Except as disclosed on Schedule 11
    hereto, there is no action, suit or proceeding pending or,
    to the Lessee's knowledge, threatened and, to the Lessee's
    knowledge, there are no facts, circumstances, conditions or
    occurrences that would reasonably be expected to form the
    basis of a Claim against the Lessee or any Unit before or by
    any Governmental Authority that (i) questions the validity
    or enforceability of the Operative Agreements to which the
    Lessee is or is to become a party or (ii) if adversely
    determined, could (whether individually or when aggregated
    with other actions, suits or proceedings) be reasonably
    expected to have a Material Adverse Effect.  The Lessee is
    not in default with respect to any order of any Governmental
    Authority except as disclosed on Schedule 11, which default
    could reasonably be expected to have a Material Adverse
    Effect.

         (f)    No Defaults; Etc.  No Lease Default or Lease
    Event of Default has occurred or is continuing.  The Lessee
    is not a party to any agreement or instrument or subject to
    any charter or other corporate restriction affecting its
    business, properties, financial condition, prospects or
    results of operations that could have a Material Adverse
    Effect.  The Lessee is not in default in, nor has any non-
    permanent waiver been granted to the Lessee with respect to
    the performance, observance or fulfillment of any of the
    obligations, covenants or conditions contained in (i) any
    agreement to which it is a party, which default could be
    reasonably expected to have a Material Adverse Effect or
    (ii) any other agreement or instrument evidencing or
    governing an outstanding principal amount of indebtedness
    equal to or in excess of Ten Million Dollars ($10,000,000).

         (g)    Financial Advisors; Broker's Fee.  The Lessee
    has not retained any broker, finder, agent (excluding Bank
    of America in its capacity as debt placement agent) or
    financial advisor in connection with the transactions
    contemplated hereby.  Neither the Lessee nor any Person
    authorized or employed by the Lessee as agent or otherwise
    has taken any action the effect of which would be to cause
    the Owner Participant, the Trust Estate, the Owner Trustee,
    the Note Purchaser, the Construction Lenders, the
    Construction Loan Agent or the Indenture Trustee to be
    liable for any brokers', finders', agents' or advisors' fees
    or commissions or costs of any nature or kind claimed by or
    on behalf of brokers, finders, agents or advisors in respect
    of the transactions contemplated by the Operative
    Agreements, except for the fees of Bank of America as debt
    placement agent.

         (h)    Status of the Lessee.  The Lessee is not an
     investment company  or an  affiliated person  of an
     investment company  within the meaning of the Investment
    Company Act of 1940, as amended.  The Lessee is not subject
    to regulation as a  Holding Company,  an  affiliate  of a
     Holding Company,  or a  Subsidiary Company  of a  Holding
    Company , within the meaning of the Public Utility Holding
    Company Act of 1935, as amended.

         (i)    Title to the Units; Security Interest.  On each
    Purchase Date (other than a Purchase Date on which only
    progress payments are being made), (A) good, marketable and
    insurable title to the Units to be settled for on such
    Purchase Date will be validly and effectively conveyed to,
    and vested in, the Owner Trustee, free and clear of all
    Liens, except the Lien of the Construction Loan Agreement
    and other Permitted Liens and (B) no filings or recordings
    are necessary to validly and effectively convey to the Owner
    Trustee good, marketable and insurable title to interest in
    such Units, in all cases free and clear of all Liens, except
    the Lien of the Construction Loan Agreement and other
    Permitted Liens, or to grant to the Construction Loan Agent,
    for the benefit of the Construction Lenders, and to perfect,
    the Lien provided for in the Construction Loan Agreement,
    except for the filings and recordings required by Section
    4.2(c).  On or prior to each Purchase Date, the Lessee shall
    have delivered to special counsel to the Construction Loan
    Agent for filing in the appropriate filing offices all
    filings and recordings required by Section 4.2(c). 
    Notwithstanding the foregoing terms of this Section 3.2(i),
    or any other term of this Agreement to the contrary, the
    parties hereto acknowledge and agree that title to the Units
    may pass to the Owner Trustee only on the Lease Term
    Commencement Date or on a limited number of dates prior
    thereto, the timing of such transfer or transfers of title
    to be subject to the terms of (x) the Turnkey Engineering,
    Procurement and Construction Agreement, dated as of July 1,
    1997, to be entered into between the Construction Agent and
    ICF Kaiser Engineers, Inc. (the "Turnkey Construction
    Contract"), and (y) prior to the execution and delivery of
    the  Turnkey Construction Contract, that certain letter of
    intent, dated as of February 14, 1997, between the
    Construction Agent and ICF Kaiser Engineers, Inc. (the
    "Construction Letter of Intent").  On the Lease Term
    Commencement Date, (a) good, marketable and insurable title
    to all Units will be vested in the Owner Trustee, free and
    clear of all Liens, except the Lien of the Lease and the
    Indenture and other Permitted Liens, (B) no filings or
    recordings are necessary to validly and effectively vest in
    the Owner Trustee good, marketable and insurable title to
    such Units, in all cases free and clear of all Liens except
    the Lien of the Lease and the Indenture and other Permitted
    Liens, and (C) upon the filing and recording of all filings
    and recordings required by Sections 4.3(c) and 4.5(b), the
    Indenture will create a valid and perfected first priority
    Lien and security interest in the Indenture Estate,
    effective as against creditors of, and purchasers from, the
    Owner Trustee and the Lessee, subject only to Permitted
    Liens and to the accuracy of  the representations and
    warranties in Sections 3.1(j) and 3.4(f).  On or prior to
    the Lease Term Commencement Date, the Lessee has caused to
    be filed in the appropriate filing offices all filings and
    recordings required by Sections 4.3(c) and 4.5(b).

         (j)    Applicable Law.  The use of the Units (whether
    taken individually, as a whole, or otherwise) in a manner
    consistent with the Operative Agreements does not violate
    any applicable law, including Environmental Laws, or
    Governmental Action, the violation of which could reasonably
    be expected to have a Material Adverse Effect.

         (k)    Event of Loss; Eminent Domain.  No Event of Loss
    has occurred; no event or condition has occurred which
    would, with the passage of time or the giving of notice, or
    both, constitute an Event of Loss; and no damage, loss,
    condemnation, confiscation, theft or seizure has occurred
    with respect to any Unit which would result in the potential
    for any other party to the Operative Agreements to fail to
    consummate the transactions contemplated hereby.  There is
    no action pending or, to the knowledge of the Lessee,
    threatened by any Governmental Authority or other Person to
    initiate a taking or use of the Units (whether taken
    individually, as a whole, or otherwise) or any part or
    portion thereof through condemnation, seizure, requisition
    of title, power of eminent domain or otherwise.

         (l)    Certificates, Permits.  The Lessee has obtained
    and is in compliance with all Governmental Actions and all
    certificates, licenses, and permits, required from all
    Governmental Authorities or from private parties, for the
    normal use and operation of the Units (whether taken
    individually, as a whole, or otherwise) that the failure to
    obtain or comply with could reasonably be expected to have a
    Material Adverse Effect and all such certificates, licenses,
    permits and the like will be final, in full force and effect
    and all applicable appeal periods shall have expired on the
    Lease Term Commencement Date.

         (m)    Chief Executive Office.  The principal place of
    business and chief executive office (as such term is used in
    Article 9 of the Uniform Commercial Code) of the Lessee and
    the office where it keeps its records concerning its
    accounts relating to the transactions contemplated hereby is
    accurately set forth opposite the Lessee's name on
    Schedule 1.

         (n)    Use of Proceeds.  None of the transactions
    contemplated by the Operative Agreements (including, without
    limitation, the use of the proceeds indirectly received by
    the Lessee from the Construction Advances or sale of the
    Note) will result in a violation of Section 7 of the
    Securities Exchange Act or any regulations issued pursuant
    thereto, including, without limitation, Regulations G, T, U
    and X of the Board of Governors of the Federal Reserve
    System, 12 C.F.R., Chapter II.

         (o)    Taxes.  All Federal and state income tax returns
    and all other material Federal and state tax returns, or
    allowable extensions thereof, required to be filed by the
    Lessee or any of its Subsidiaries have, in fact, been filed,
    and all taxes which are shown to be due and payable in such
    returns or extensions have been paid.  Except as described
    on Schedule 11 hereto, no controversy in respect of
    additional income or other material taxes due is pending or,
    to the knowledge of the Lessee threatened, other than any
    such controversy which, if prosecuted, would result solely
    in a Permitted Lien.

         (p)    Disclosure.  The information disclosed in
    writing by or on behalf of the Lessee to the Owner
    Participant, the Note Purchaser or the Construction Lenders
    (including, without limitation, in any memorandum prepared
    in connection with the placement of the Note and financial
    statements) in connection with the negotiation of the
    Operative Agreements and the transactions contemplated
    hereby and thereby, when taken as a whole with all other
    written disclosures to such parties by the Lessee, do not
    contain an untrue statement of a material fact or omit to
    state a material fact necessary to make the statements
    herein or therein, in light of the circumstances under which
    they were made, not misleading.  There is no fact known to
    the Lessee that has not been disclosed to the Owner
    Participant and the Note Purchaser in writing that could
    reasonably be expected to have a Material Adverse Effect.

         (q)    Subjection to Government Regulation.  Except as
    disclosed on Schedule 11 hereto, none of the Owner
    Participant, any Construction Lender, the Construction Loan
    Agent, the Indenture Trustee or any Note Purchaser will
    become (i) solely by reason of entering into the Operative
    Agreements or the consummation of the transactions
    contemplated thereby, subject to ongoing regulation of its
    operations by any Governmental Authority; or (ii) upon the
    exercise of remedies under the Indenture or the Lease or
    upon the expiration thereof, other than with respect to
    environmental permits needed for the operation of the Units
    (taken together as a whole) and which Lessee has obtained
    and which remain in full force and effect, subject to
    ongoing regulation of its operations by any Governmental
    Authority.

         (r)    Unsatisfied Judgments.  There are no material
    outstanding unsatisfied judgments, tax liens or bankruptcy
    proceedings against the Lessee.

         (s)    Foreign Person.  The Lessee is not a foreign
    person as defined in Section 1445 of the Code.

         (t)    ERISA.

                (i)     Prohibited Transactions.  Neither the
         execution of the Operative Agreements nor the
         consummation of any transaction contemplated thereby,
         including the making by the Owner Participant of its
         investment or the holding by it of the Beneficial
         Interest, the making or holding by the Construction
         Lenders of the Construction Advances or the purchase or
         holding by the Note Purchaser of the Note, will
         constitute a "prohibited transaction" (as defined in
         section 406 of ERISA or section 4975 of the Code).  It
         is understood that, in making the representation set
         out in this Section 3.2(t)(i), the Lessee is relying,
         to the extent applicable, upon the representation of
         the Owner Participant set forth at Section 3.4(i), upon
         the representation of the Construction Lenders set
         forth at Section 3.5(f) and upon the representation of
         the Note Purchaser set forth at Section 3.5(e). 

                (ii)    Pension Plans.

                   (A)  Compliance with ERISA.  The Lessee and
                the ERISA Affiliates are in compliance with
                ERISA and the Code, except for such failures to
                comply that, in the aggregate for all such
                failures, could not reasonably be expected to
                have a Material Adverse Effect.  To the best of
                the Lessee's knowledge, there have been no
                "reportable events" (as defined in section 4043
                of ERISA) with respect to any Pension Plan that
                could result in the termination of such Pension
                Plan and give rise to a liability of the Lessee
                or any ERISA Affiliate in respect thereof that
                could reasonably be expected to have a Material
                Adverse Effect.

                   (B)  Funding Status.  No "accumulated funding
                deficiency" (as defined in section 302 of ERISA
                and section 412 of the Code) exists with respect
                to Pension Plans of the Lessee, and no ERISA
                Affiliate has an accumulated funding deficiency. 
                Neither the Lessee nor any ERISA Affiliate has
                failed to make any contribution or payment to
                any Pension Plan which has resulted, or could
                reasonably be expected to result, in the
                imposition of a Lien under section 302(f) of
                ERISA or section 412(n) of the Code.

                   (C)  PBGC.  No liability to the Pension
                Benefit Guaranty Corporation (the "PBGC") has
                been or is expected to be incurred by the Lessee
                or any ERISA Affiliate with respect to any
                Pension Plan that, individually or in the
                aggregate, could reasonably be expected to have
                a Material Adverse Effect.  No circumstance
                exists that constitutes or reasonably could be
                expected to constitute grounds under section
                4042 of ERISA entitling the PBGC to institute
                proceedings to terminate, or appoint a trustee
                to administer, any Pension Plan or trust created
                thereunder, nor has the PBGC instituted any such
                proceeding.

                   (D)  Multiemployer Plans.  Neither the Lessee
                nor any ERISA Affiliate has incurred or
                presently expects to incur any withdrawal
                liability under Title IV of ERISA with respect
                to any Multiemployer Plan that could reasonably
                be expected to have a Material Adverse Effect. 

         (u)    Sales Tax.  On each Purchase Date (other than
    one on which only progress payments are being made) and on
    the Lease Term Commencement Date, all sales or use taxes
    relating to the sale to the Owner Trustee of the Units to be
    settled for on such Purchase Date or on the Lease Term
    Commencement Date (if any), as the case may be, which are
    then due will have been paid in full or adequate provision
    for the payment of which will have been made.

         (v)    Description of Units.  The description of the
    Units with respect to a Purchase Date set forth in the
    Purchase Notice delivered in connection with such Purchase
    Date is, or will be, a true and correct description of the
    Units being sold on such date in all material respects.

         (w)    Condition of Units.  No event or condition
    currently exists that (i) presently adversely affects the
    operation or maintenance of any of the Units (whether taken
    together as a functional whole or individually) or (ii)
    causes the Lessee to believe that the functional ability of
    the Units (whether taken together as a functional whole or
    individually) is less than the functional ability for which
    the Units were designed.

         (x)    Lease of Real Property.  Except as set forth on
    Schedule 7, the Lessee holds a valid leasehold interest
    under the Ground Lease to each parcel of real property upon
    which any Unit leased or to be leased by the Lessee will be
    located;  and no Unit leased or to be leased by the Lessee
    will be or become subject to any Liens, rights of distraint,
    charges, encumbrances or Claims created by or through Lessee
    as a result of such Unit being located upon such owned or
    leased real property, except for Permitted Liens.

         (y)    Intellectual Property.  All third party
    licenses, patents, trademarks, tradenames and similar
    rights, if any, necessary for the operation of the Units
    (whether taken together as a functional whole or
    individually) by the Lessee or a third party are in full
    force and effect and have been, or on the Lease Term
    Commencement will be, duly assigned or licensed to the Owner
    Trustee; it being understood that such licenses, patents,
    trademarks, tradenames and similar rights do not include
    licenses, patents, trademarks, tradenames and similar rights
    related to the products produced by the Lessee with the
    Units.

         (z)    Environmental Matters.  

                (i)     Lessee is in compliance, in all material
         respects, with all Environmental Laws and the
         requirements of any permits issued under such Laws.

                (ii)    Lessee has not generated, used, treated,
         recycled, stored, released or disposed of, or permitted
         the generation, use, treatment, recycling, storage,
         release or disposal of Hazardous Substances at, on or
         under all or a portion of the Premises or transported
         or permitted the transportation of Hazardous Substances
         to or from the Premises, the Units and Easements,
         except as necessary for the construction and operation
         of Lessee's business and in compliance in all material
         respects with all applicable Environmental Laws.

                (iii)   There are no pending or, to the best
         knowledge of Lessee, threatened Environmental Claims
         against Lessee or the Premises, the Units and    
         Easements.

    The parties acknowledge that the Easements are used in
    connection with many operations (in addition to the
    operations of Lessee) and that the representations and
    covenants made in this Agreement with respect to Easements
    apply only to activities involving the Premises or the
    Units.

    3.3  Representations and Warranties of the Indenture Bank
and the Indenture Trustee.  Indenture Bank, in its individual
capacity and in its capacity as Indenture Trustee as set forth
below, represents and warrants to the other parties hereto that:

         (a)    Organization and Power.  Indenture Bank is a
    banking corporation duly organized, validly existing and in
    good standing under the laws of the State of Delaware and
    has full corporate power, authority and legal right to carry
    on its business as now conducted and to enter into and
    perform its obligations hereunder and under each of the
    other Indenture Trustee Agreements.

         (b)    Authorization, Execution and Validity. 
    Indenture Bank has duly authorized, executed and delivered
    each of the Indenture Trustee Agreements other than those to
    be executed and delivered on the Lease Term Commitment Date,
    and, as of the Lease Term Commitment Date, the Indenture
    Trustee Agreements to be delivered on the Lease Term
    Commencement Date also will have been duly authorized,
    executed and delivered (and in the case of the Note, duly
    authenticated) by it.  Assuming that each of the Indenture
    Trustee Agreements constitutes, or when entered into will
    constitute, a legal, valid and binding obligation of all
    other parties thereto, enforceable against such parties in
    accordance with their respective terms, this Agreement
    constitutes, and each of the other Indenture Trustee
    Agreements when entered into by the Indenture Bank will
    constitute, the legal, valid and binding obligation of
    Indenture Bank, enforceable against it in its individual
    capacity (to the extent expressly provided therein) in
    accordance with its respective terms, except as
    enforceability may be limited by bankruptcy, insolvency,
    reorganization, moratorium or other laws affecting the
    enforcement of creditors', mortgagees' or lessors' rights in
    general and by general principles of equity (regardless of
    whether such enforceability is considered in a proceeding in
    equity or at law).

         (c)    Further Validity Warranty.  Assuming that each
    of the Indenture Trustee Agreements constitutes, or when
    entered into will constitute, a legal, valid and binding
    obligation of all other parties thereto, enforceable against
    such parties in accordance with their respective terms, each
    of the Indenture Trustee Agreements constitutes, or when
    entered into by the Indenture Trustee will constitute, a
    legal, valid and binding obligation of Indenture Trustee
    enforceable against it in accordance with its respective
    terms, except as enforceability may be limited by
    bankruptcy, insolvency, reorganization, moratorium or other
    laws affecting the enforcement of creditors', mortgagees' or
    lessors' rights in general and by general principles of
    equity (regardless of whether such enforceability is
    considered in a proceeding in equity or at law).

         (d)    No Conflict.  The execution, delivery and
    performance by Indenture Bank and Indenture Trustee of each
    Indenture Trustee Agreement and compliance by Indenture Bank
    and Indenture Trustee with all of the provisions thereof
    binding upon it do not and will not contravene any order of
    any Governmental Authority or any law or regulation of the
    United States of America or the State of Delaware, in each
    case  governing the banking or trust powers of Indenture
    Bank, or contravene the provisions of, or constitute a
    default by Indenture Bank under, or result in the creation
    of any Lien (except for Permitted Liens upon the Units) upon
    the Indenture Estate under its corporate charter or by-laws
    or any indenture, mortgage, contract or other agreement or
    instrument to which Indenture Bank is a party or by which
    Indenture Bank or any of its property is bound or affected.

         (e)    Litigation.  There are no proceedings pending
    or, to the knowledge of Indenture Bank, threatened against
    Indenture Bank, in its individual capacity or as Indenture
    Trustee, before any Governmental Authority governing the
    banking or trust powers of the Indenture Bank or the
    Indenture Trustee which individually or in the aggregate
    would impair the ability of the Indenture Bank or the
    Indenture Trustee to perform its respective obligations
    under this Agreement or any other Indenture Trustee
    Agreement or which question the validity of this Agreement
    or any other Indenture Trustee Agreement or any action taken
    or to be taken pursuant hereto or thereto.  Indenture Bank
    is not in default with respect to any order of any
    Governmental Authority governing the banking or trust powers
    of the Indenture Bank, the default under which would affect
    adversely the ability of the Indenture Bank or the Indenture
    Trustee to perform its obligations under this Agreement or
    any other Indenture Trustee Agreement.

         (f)    Consents.  No consent, approval or authorization
    of, or filing, registration or qualification with, or giving
    of notice or taking of any other action with respect to, any
    state or local Governmental Authority or any United States
    federal Governmental Authority regulating the banking or
    trust powers of Indenture Bank is required in connection
    with the execution, delivery and performance by Indenture
    Bank, in its individual capacity or as Indenture Trustee, of
    any of the transactions contemplated hereby or of any of the
    transactions contemplated by any of the other Indenture
    Trustee Agreements, other than any such consent, approval,

    in full force and effect.

         (g)    Default.  The Indenture Trustee is not in
    default under any of the Indenture Trustee Agreements.

    3.4  Representations and Warranties of the Owner
Participant.  The Owner Participant represents and warrants to
the other parties hereto that:

         (a)    Organization and Power.  The Owner Participant
    is a corporation duly organized, validly existing and in
    good standing under the laws of the State of Delaware, has
    the power, authority and legal right to carry on its
    business as now conducted, and has the power, authority and
    legal right to execute, deliver and perform its obligations
    under the Owner Participant Agreements.

         (b)    Authorization, Execution and Validity.  The
    Owner Participant Agreements have been duly authorized by
    all necessary action, executed and delivered (or, in the
    case of each other Owner Participant Agreement executed and
    delivered in relation to a Purchase Date or the Lease Term
    Commencement Date, on such Purchase Date or the Lease Term
    Comment Date, as the case may be, will have been duly
    executed and delivered) by the Owner Participant; and
    (assuming the due authorization, execution and delivery by
    each other party thereto) constitute (or, in the case of
    each other Owner Participant Agreement executed and
    delivered in relation to a Purchase Date or the Lease Term
    Commencement Date, on such Purchase Date or the Lease Term
    Commencement Date, as the case may be, will constitute)
    legal, valid and binding obligations of the Owner
    Participant, enforceable against it in accordance with their
    respective terms, except as enforceability may be limited by
    bankruptcy, insolvency, reorganization, moratorium or other
    laws affecting the enforcement of creditors', mortgagees' or
    lessors' rights in general and by general principles of
    equity (regardless of whether such enforceability is
    considered in a proceeding in equity or at law).

         (c)    No Conflict.  The execution, delivery and
    performance by the Owner Participant of each Owner
    Participant Agreement and compliance by the Owner
    Participant with all of the provisions thereof do not and
    will not contravene any law or regulation, or any order of
    any Governmental Authority applicable to or binding on the
    Owner Participant (it being understood that the Owner
    Participant makes no representation or warranty relating to
    the nature of the Units or the Premises or the laws,
    regulations or orders pertaining thereto or pertaining to
    the use thereof), or contravene the provisions of, or
    constitute a default by the Owner Participant under, or
    result in the creation of any Lien (except for Permitted
    Liens upon the Units) upon the Units under its certificate
    of incorporation or any indenture, mortgage, contract or
    other agreement or instrument to which the Owner Participant
    is a party or by which the Owner Participant or any of its
    property is bound or affected.  The representation and
    warranty contained in this Section 3.4(c) does not
    constitute any representation or warranty as to ERISA or
    regulations thereunder.

         (d)    Litigation.  There is no action, suit or
    proceeding pending or, to the knowledge of the Owner
    Participant, threatened against the Owner Participant before
    or by any Governmental Authority that (i) questions the
    validity or enforceability of any Owner Participant
    Agreement or (ii) if adversely determined (whether
    individually or when aggregated with other actions, suits or
    proceedings) would materially and adversely affect its
    ability to perform its obligations under the Owner
    Participant Agreements.  The Owner Participant is not in
    default with respect to any order of any Governmental
    Authority, the default under which would materially affect
    adversely the ability of the Owner Participant to perform
    its obligations under the Owner Participant Agreements.

         (e)    Governmental Actions.  No Governmental Action on
    the part of the Owner Participant is required in connection
    with the execution, delivery and performance by the Owner
    Participant of the Owner Participant Agreements (it being
    understood that the Owner Participant makes no
    representation or warranty relating to the nature of the
    Units or the Premises or the laws, regulations or orders
    pertaining thereto).

         (f)    No Liens.  The Trust Estate is free of any
    Lessor's Liens attributable to the Owner Participant. 

         (g)    Default.  The Owner Participant is not in
    default under any of the Owner Participant Agreements.  No
    Indenture Default or Indenture Event of Default with respect
    to the Owner Participant has occurred and is continuing.

         (h)    Investment Company.  The Owner Participant is
    not an  investment company  or an  affiliated person  of an
     investment company  within the meaning of the Investment
    Company Act of 1940, as amended.

         (i)    ERISA.  The Owner Participant is not an
     employee benefit plan  within the meaning of Section 3(3)
    of ERISA which is subject to Title I of ERISA, or a  plan 
    within the meaning of Section 4975 of the Code or an entity
    that is deemed to hold  plan assets  within the meaning of
    29 C.F.R. Section 2510.3-101 of any such employee benefit plan or
    plan (collectively, an "ERISA Plan"), and no part of the
    funds to be advanced by the Owner Participant pursuant to
    Section 2.4 will constitute assets of an ERISA Plan.

         (j)    Broker's Fees.  Neither the Owner Participant
    nor any Person authorized or employed by the Owner
    Participant as agent or otherwise has taken any action the
    effect of which would be to cause the Trust Estate, the
    Owner Trustee, the Lessee, the Note Purchaser, the
    Construction Lenders, the Construction Loan Agent or the
    Indenture Trustee to be liable for any brokers', finders',
    agents' or advisors' fees or commissions or costs of any
    nature or kind claimed by or on behalf of brokers, finders,
    agents or advisors in respect of the transactions
    contemplated by the Operative Agreements.

    3.5  Representations, Warranties and Covenants Regarding
Beneficial Interest and Notes.

         (a)    Offers by the Owner Trustee.  Boatmen's
    represents and warrants to the other parties hereto that, as
    of the date hereof, as of each Advance Date and as of the
    Lease Term Commencement Date, neither the Owner Trustee
    (whether acting in its individual capacity or as Owner
    Trustee) nor any Person authorized or employed by the Owner
    Trustee as agent or otherwise in connection with the
    placement of any interest in the Construction Notes, the
    Note, the Beneficial Interest, the Trust Estate, the
    Indenture Trust Estate, the Lease, the Bayer Letter or the

         (b)    Offers by the Lessee.  The Lessee represents and
    warrants to the other parties hereto that, as of the date
    hereof, as of each Advance Date and as of the Lease Term
    Commencement Date, it has not, nor has any Person authorized
    or employed by it as agent or otherwise in connection with

    Letter or the Bayer Support Agreement, or any similar
    securities of the Lessee or the Owner Trustee, for sale to,
    or directly or indirectly solicited any offers to buy any
    thereof from, or otherwise approached or negotiated with
    respect thereto with, any Person in violation of the
    Securities Act or any state securities laws, and neither it
    nor any Person authorized or employed by it as agent or
    otherwise in connection with the placement of the
    Construction Notes or the Note, the Beneficial Interest, the
    Trust Estate, the Indenture Estate, the Lease, the Bayer
    Letter or the Bayer Support Agreement has taken any action
    which would subject any interest in the Construction Notes,
    the Units, the Note, the Beneficial Interest, the Trust
    Estate, the Indenture Estate, the Lease, the Bayer Letter or
    the Bayer Support Agreement to the registration requirements
    of Section 5 of the Securities Act or any state securities
    laws.

         (c)    Securities Covenant.  Each of the Owner Trustee
    and the Lessee covenants and agrees as to itself that
    neither it nor anyone acting on the behalf of it will: 

                (i)     offer the Beneficial Interest, the Trust
         Estate or any part thereof or any similar security for
         issue or sale to, or solicit any offer to acquire any
         thereof from, or otherwise approach or negotiate with,
         anyone so as to violate the provisions of Section 5 of
         the Securities Act, or any state securities laws, or

                (ii)    offer the Construction Notes, the Notes
         or any part thereof or any similar security for issue
         or sale to, or solicit any offer to acquire any thereof
         from, or otherwise approach or negotiate with, anyone
         so as to violate the provisions of Section 5 of the
         Securities Act or any state securities laws.

         (d)    Purchase for Investment.  Each Participant
    represents and warrants to each other Participant, the
    Lessee, and the Trustees that, as of the Lease Term
    Commencement Date, such Participant is purchasing the
    Interest (as hereinafter defined) to be acquired by it for
    its account with no present intention of distributing such
    Interest or any part thereof in any manner which would
    violate the Securities Act or state securities laws, but
    without prejudice, however, to the right of such Participant
    at all times to sell or otherwise dispose of all or any part
    of such Interest in compliance with the Securities Act and
    any state securities laws and, in the case of the Owner
    Participant, Section 6.1 hereof or, in the case of the Note
    Purchaser, Section 6.13 hereof.  The Beneficial Interest and
    the Notes are sometimes referred to in the Operative
    Agreements collectively as the  Interests  and individually
    as an "Interest".

         (e)    ERISA Representation, Warranty and Covenant of
    Note Purchaser.  The Note Purchaser represents, warrants and
    covenants that either (i) no part of the funds used by it to
    acquire and hold any Note constitutes assets of an ERISA
    Plan; or (ii) the source of funds used to acquire and hold
    any Note is an "insurance company general account" within
    the meaning of Department of Labor Prohibited Transaction
    Exemption ( PTE ) 95-60 (issued July 12, 1995), and there is
    no employee benefit plan (treating as a single plan all
    plans maintained by the same employer or employee
    organization) with respect to which the aggregate amount of
    the general account reserves and liabilities for all
    contracts held by or on behalf of such plan exceed 10% of
    the total reserves and liabilities of such general account
    (exclusive of separate account liabilities) plus surplus, as
    set forth in such Note Purchaser's most recent annual
    statement in the form required by the National Association
    of Insurance Commissioners as filed with such Note
    Purchaser's state of domicile.  Any transferee of a Note
    shall by its acceptance of such Note be deemed to make one
    of the above representations and covenants to Lessee, Owner
    Participant, Owner Trustee and Indenture Trustee regarding
    the source of funds used to purchase and hold such Note.

         (f)    ERISA Representation, Warranty and Covenant of
    each Construction Lender.  Each Construction Lender
    represents, warrants and covenants to each of the other
    parties that (i) it is not an ERISA Plan, and (ii) no part
    of the funds used by it to fund and hold any Construction
    Advance constitutes assets of an ERISA Plan.

         (g)    Reaffirmation on the Lease Term Commencement
    Date.  The purchase of the Note by the Note Purchaser on the
    Lease Term Commencement Date shall constitute a
    reaffirmation by such Note Purchaser of its representations
    and warranties set forth in this Section 3.5 as of the Lease
    Term Commencement Date.  

         (h)    Tax Status of Bayerische.  Bayerische is
    acquiring its interest in the Note and any Construction
    Advance through its New York branch and all principal,
    interest and Premium, if any, generated by the Note and any
    Construction Advance is expected to be  effectively
    connected  (within the meaning of Section 1441(c) of the
    Code and the regulations thereunder) with the conduct of
    Bayerische's trade or business in the United States.  The
    Internal Revenue Service Forms 4224 delivered by Bayerische
    to the Owner Participant, the Indenture Trustee, the Lessor
    and the Lessee on the date hereof are true and correct and
    Bayerische has obtained all approvals needed to execute and
    deliver such Forms.

    have received an executed counterpart of the Private
    Placement Certificate.

         (i)    No Change in Law or Material Rent Adjustment. 
    No change of law shall have occurred that, in the opinion of
    Lessee, renders the transactions contemplated herein
    illegal; and no rent adjustment shall be proposed which, in
    the opinion of Lessee, renders the transactions uneconomic
    to Lessee, provided that if all adjustments to Base Rent
    result in an increase of the present value of Base Rent
    (other than adjustments relating to the interest rate upon
    the Debt) by less than 200 basis points, such adjustments
    shall not be deemed to be uneconomic.

         (j)    Completion. Completion shall have occurred,
    provided, however, that any failure of completion to occur
    which is a result of the actions or inactions of the Lessee
    shall not be deemed a failure of Completion for purposes of
    this Section 4.6.

    4.7  Opinion Acknowledgment. Each of the parties hereto,
with respect to such party, expressly consents to the rendering
by its counsel of the opinion referred to in Sections 4.1(b),
4.3(h), 4.5(d) and 4.6(c) and acknowledges that such opinion
shall be deemed to be rendered at the request and upon the
instructions of such party, each of whom has consulted with and
has been advised by its counsel as to the consequences of such
request, instructions and consent.

    4.8  Further Condition To Participants' Commitment.  The
obligation of each Construction Lender to make any Construction
Advance, and the obligation of each Participant to make its
investment specified in Section 2 on the Lease Term Commencement
Date, shall be further subject to the condition that no material
adverse change shall have occurred in (x) the condition,
financial or otherwise, of the Lessee or Bayer from its condition
as of December 31, 1996, and (y) Bayer's ability to perform its
obligations under the Support Documents.

SECTION 6       CERTAIN COVENANTS OF THE PARTICIPANTS, THE OWNER 
         TRUSTEE, THE INDENTURE TRUSTEE AND THE LESSEE          

    6.1  Restrictions on Transfer of Beneficial Interest.  The
Owner Participant covenants and agrees with and for the benefit
of the other parties to this Agreement that without the consent
of the Lessee and a Majority In Interest, the Owner Participant
will not sell, convey, assign or otherwise transfer all or a
portion of its Beneficial Interest or its right and interest in
and to this Agreement, the Tax Indemnity Agreement, the Trust
Agreement and the other Operative Agreements prior to the
expiration or earlier termination of the Lease Term (except by
merger or consolidation) unless:

         (a)    Transferee Qualifications.   The Person to whom
    such transfer is to be made (a "Transferee") is an Eligible
    OP Assignee.

         (b)    Notice.  The Owner Trustee, Indenture Trustee
    and the Lessee shall have received 15 days' prior written
    notice of such transfer specifying the name and address of
    any proposed Transferee and such additional information as
    shall be necessary to determine whether the proposed
    transfer satisfies the requirements of this Section 6.1.

         (c)    Transfer Agreement and Opinion of Counsel.  Such
    Transferee enters into an agreement substantially in the
    form of Exhibit N hereto and provides the Indenture Trustee,
    the Note Purchaser, the Owner Trustee and the Lessee with an
    opinion of counsel (whose fees and expenses shall not be the
    obligation of the Lessee) covering the matter referred to in
    clause (d) below and stating that such agreement has been
    duly authorized, executed and delivered by such Transferee
    and constitutes the legal, valid and binding contract of
    such Transferee, enforceable against such Transferee in
    accordance with its terms (subject to customary
    qualifications).

         (d)    No Violation of Law.  Such transfer complies in
    all respects with and does not violate any applicable law.

         (e)    Expenses.  All fees, expenses and charges of the
    parties hereto (including, without limitation, reasonable
    legal fees and expenses of special counsel) incurred in
    connection with each transfer of such Beneficial Interest is
    paid by an Owner Participant, as specified in the agreement
    entered into pursuant to Section 6.1(c).

         (f)    ERISA.  Such Transferee makes the representation
    set forth in Section 3.4(i) to the parties hereto.

         (g)    Default.  As a result of such transfer, no
    Indenture Default attributable to the Owner Participant or
    the Owner Trustee shall have occurred and be continuing.

         (h)    Non-Competitor.  Such Transferee is not a
    Competitor, unless the Lessee and Bayer shall have otherwise
    consented in writing.

         (i)    Number of Owner Participants.  After giving
    effect to such transfer, there are no more than three (3)
    Owner Participants.

In connection with any such transfer, the Lessee shall represent
to the Transferee that no Lease Default, Lease Event of Default
or, except as disclosed pursuant to the Lease, Event of Loss then
exists.  Upon any such transfer (x) except as the context
otherwise requires, such Transferee shall be deemed an  Owner
Participant  for all purposes, and shall enjoy the rights and
privileges and perform the obligations of the transferor Owner
Participant to the extent of the interest transferred hereunder
and under each other Operative Agreement to which the transferor
Owner Participant is a party, and, except as the context
otherwise requires, each reference in this Agreement and each
other Operative Agreement to the  Owner Participant  shall
thereafter be deemed to include such Transferee for all purposes
to the extent of the interest transferred, and (y) the transferor
shall be released from all obligations hereunder and under each
other Operative Agreement to which such transferor is a party or
by which such transferor is bound to the extent such obligations
are expressly assumed by a Transferee.  In no event shall any
such transfer or assignment waive or release the transferor from
any liability on account of any breach existing immediately prior
to such transfer of any of its representations, warranties,
covenants or obligations set forth in the Operative Agreements or
for any fraudulent or wilful misconduct.  Any transfer,
conveyance or assignment of the Owner Participant's Beneficial
Interest hereunder in violation of this Section 6.1 shall be void
and of no effect, unless such transfer, conveyance or assignment,
on its face, at the time of occurrence appears to comply with the
requirements of this Section 6.1; and the effectiveness of a
transfer, conveyance or assignment which appears on its face to
comply with the requirements of this Section 6.1, however, shall
not impair any other right or remedy which any party may have as
a result of such transfer, conveyance or assignment actually
violating this Section 6.1.  In the event that there is more than
one Owner Participant, any consent, waiver or amendment with
respect to the Operative Agreements may be given by those Owner
Participants that hold more than 50% of the aggregate amount
invested by the Owner Participants, except that without the
consent of each Owner Participant affected thereby, no consent,
amendment or waiver may (i) reduce any amount payable as Basic
Rent or Supplemental Rent, or change the date on which any such
amount is payable, (ii) create or allow any Liens on the Units
other than Permitted Liens, (iii) affect any Excepted Property or
(iv) reduce the percentage required to approve consents, waivers
and amendments set forth in this sentence.
 
    6.2  Liens Attributable to the Owner Participant.  The Owner
Participant covenants and agrees with and for the benefit of the
other parties to this Agreement that the Owner Participant will
not directly or indirectly create, incur, assume or suffer to
exist:  (a) any Lessor's Liens created by it (whether or not
through its act or failure to act), or (b) any Lessor's Liens
arising as a result of taxes described in clause (iii) of the
definition of Lessor's Liens which are imposed against the Owner
Trustee (not in its individual capacity but solely as Owner
Trustee); and the Owner Participant agrees that it will, at its
own cost and expense, take such action as may be necessary to
duly discharge and satisfy in full any such Lessor's Lien (by
bonding or otherwise); provided that the Owner Participant may
contest any such Lessor's Lien in good faith by appropriate
proceedings so long as such proceedings do not involve any
material danger of the sale, forfeiture or loss of the Trust
Estate or any interest therein and do not interfere with the use,
operation or possession of the Units by the Lessee under the
Lease or the rights, titles and interests of the Construction
Loan Agent under the Construction Loan Agreement or the Indenture
Trustee under the Indenture.  The Owner Participant agrees to
hold harmless the other parties to this Agreement from and
against any loss, cost or expense (including reasonable legal
fees and disbursements) as the result of the existence of any
such Lessor's Lien or the failure of the Owner Participant to
discharge and satisfy any such Lessor's Lien.

    6.3  Lessor's Liens Attributable to the Owner Trustee. 
Boatmen's covenants and agrees with and for the benefit of the
other parties to this Agreement that Boatmen's will not directly
or indirectly create, incur, assume or suffer to exist any
Lessor's Liens attributable to it (whether or not through its act
or failure to act), and Boatmen's agrees that it will, at its own
cost and expense, take such action as may be necessary to duly
discharge and satisfy in full any such Lessor's Lien (by bonding
or otherwise).  Boatmen's agrees to hold harmless the other
parties to this Agreement from and against any loss, cost or
expense (including reasonable legal fees and disbursements) as
the result of the existence of any such Lessor's Lien or the
failure of Boatmen's to discharge and satisfy any such Lessor's
Lien.

    6.4  Liens Created by the Indenture Trustee.  The Indenture
Trustee, in its individual capacity, covenants and agrees with
and for the benefit of the other parties to this Agreement that: 
(a) it shall not cause or permit to exist any Lien on the Units
or all or any other portion of the Trust Estate or the Indenture
Estate arising as a result of (i) claims against the Indenture
Trustee, in its individual capacity, not related to its interest
in the Units or any other portion of the Trust Estate, or the
administration of the Indenture Estate pursuant to the Indenture,
(ii) acts, or failures to act, of the Indenture Trustee, in its
individual capacity, not contemplated, or failure of the
Indenture Trustee to take any action it is expressly required to
perform, by the Operative Agreements, (iii) claims against the
Indenture Trustee in its individual capacity relating to taxes or
expenses that are not indemnified against by the Lessee pursuant
to Section 7 attributable to the Indenture Trustee, in its
individual capacity, or (iv) claims against the Indenture Trustee
arising out of the transfer by the Indenture Trustee (without the
consent of the Lessee and the Owner Trustee and not pursuant to
the direction of the holders of Notes pursuant to the terms of
the Indenture) of all or any portion of its interest in the
Units, the Indenture Estate or the Operative Agreements, other
than a transfer expressly contemplated by the Operative
Agreements; and (b) the Indenture Trustee will, at its own cost
and expense (and without any right of reimbursement from any
other party hereto), promptly take such action as may be
necessary to duly discharge and satisfy in full any such Lien (by
bonding or otherwise).  The Indenture Trustee agrees to hold
harmless the other parties to this Agreement from and against any
loss, cost or expense (including reasonable legal fees and
disbursements) as the result of the existence of any such Lien or
the failure of the Indenture Trustee to discharge and satisfy any
such Lien.

    6.5  Certain Covenants of the Owner Trustee, the Owner
Participant and Boatmen's.  The Owner Participant and Boatmen's
hereby covenant and agree, severally and not jointly, with and
for the benefit of the Lessee, the Indenture Trustee, the
Construction Loan Agent, the Construction Lenders and the Note
Purchaser: (a) not to amend, supplement or otherwise modify any
provision of the Trust Agreement in such a manner as to adversely
affect the rights of the Lessee, the Indenture Trustee, the
Construction Loan Agent, the Construction Lenders or the Note
Purchaser, without the prior written consent of the affected
party and (b) not to terminate or revoke the Trust Agreement, or
the trust created by the Trust Agreement, and such trust shall
not be subject to revocation or termination by the Owner
Participant, prior to the latest of (i) payment in full and
discharge of the Construction Advances and all other indebtedness
secured by the Construction Loan Agreement, (ii) payment in full
and discharge of the Notes and all other indebtedness secured by
the Indenture and the final discharge thereof pursuant to Section
10.1 thereof and (iii) the expiration or early termination of the
Lease and (c) so long as the Lien of the Indenture has not been
discharged in accordance with the terms thereof, not to declare a
Lease Event of Default under the Lease except as expressly
permitted by the terms of the Indenture.

    6.6  Lessee's Merger Covenant.  (a) The Lessee shall not
consolidate with or merge into any other Person, or permit any
other Person to merge or consolidate with or into it, or convey,
transfer or lease substantially all of its assets as an entirety
to any Person without the consent of the Owner Participant, the
Required Construction Lenders and the Construction Loan Agent
(for so long as any Construction Advance is outstanding) and a
Majority In Interest unless (i) the Person formed by such
consolidation or surviving such merger (if other than the Lessee)
or the Person which acquires by conveyance, transfer or lease
substantially all of the assets of the Lessee as an entirety (A)
is a domestic corporation organized and existing under the laws
of the United States of America or a political subdivision
thereof, and (B) shall execute and deliver to the Owner Trustee,
the Owner Participant, the Indenture Trustee, the Construction
Lenders, the Construction Loan Agent and the Note Purchaser an
agreement, in form and substance satisfactory to the Owner
Trustee, the Owner Participant, the Indenture Trustee, the
Required Construction Lenders and the Construction Loan Agent
(for so long as any Construction Advance is outstanding) and a
Majority In Interest, containing the express assumption by such
successor Person of the due and punctual performance and
observance of each covenant and condition of this Agreement and
each of the other Operative Agreements to be performed or
observed by the Lessee, (ii) immediately prior to and immediately
after giving effect to such transaction, no Lease Default or
Lease Event of Default shall have occurred, whether as a result
of such consolidation or merger or such conveyance, transfer or
lease or otherwise, (iii) immediately after giving effect to such
transaction, such successor Person shall be in compliance with
all of the terms and conditions of the Operative Agreements and
(iv) such successor Person shall deliver to the Owner Trustee,
Owner Participant, the Indenture Trustee, the Construction
Lenders and the Construction Loan Agent (for so long as any

binding obligation of, and is enforceable against, such successor

transaction provided in this Section 6.6 have been complied with. 
Upon such consolidation or merger, or any conveyance, transfer or
lease of substantially all of the assets of the Lessee as an
entirety in accordance with this Section 6.6, the successor
Person formed by such consolidation or into which the Lessee is
merged or to which such conveyance, transfer or lease is made
shall succeed to, and be substituted for, and may exercise every
right and power of, the Lessee, as the case may be, under this
Agreement and the other Operative Agreements with the same effect
as if such successor Person had been named as the Lessee herein
and therein.  No such consolidation, merger, conveyance, transfer
or lease of all or substantially all of the assets of the Lessee
as an entirety shall have the effect of releasing the Lessee or
any successor Person from its liability under the Operative
Agreements.  Nothing contained in this Section 6.6 shall permit
any lease, sublease, assignment or other arrangement for the use,
operation or possession of the Units except in compliance with
the applicable provisions of the Lease.

    6.7  Lessee Not to Own Notes or Beneficial Interest.

Trustee, the Owner Participant, the Indenture Trustee, the
Construction Loan Agent (for so long as any Construction Advance
is outstanding), the Required Construction Lenders (for so long
as any Construction Advance is outstanding) and a Majority In
Interest consent thereto; provided that neither the Lessee nor

of the Code).

    6.8  Broker's Fees.

    (a)  Lessee.  The Lessee covenants and agrees that it will
hold the Owner Participant, the Owner Trustee, the Indenture
Trustee, the Construction Lenders, the Construction Loan Agent

its business, and (y) the loss of which could not have a Material
Adverse Effect.

    transfer, increase the Lessee's costs or obligations (other
    than non-material administrative costs and obligations),
    unless the Lessee shall have otherwise consented; and

         (e)    in the case of a transfer to an Eligible Lender
    Assignee which is organized under the laws of any
    jurisdiction other than the United States or any state

         (c)    During the Lease Term, Lessee shall conduct and
    complete any investigation and undertake any Cleanup,
    removal, remedial or other action required by a Governmental
    Authority or Environmental Laws to remove and remediate all
    Hazardous Substances released during the Lease Term, at, on,
    in, under or emanating from the Premises, the Units and
    Easements, including such investigation, Cleanup, removal,
    remedial or other action on properties adjacent to the
    Premises to the extent permitted by the Facility Documents
    or Environmental Laws.

         (d)    During the Lease Term, Lessee shall provide
    written notice to the Owner Participant, Owner Trustee,
    Indenture Trustee and the holders of the Notes of (i) any
    fact, circumstance, condition, occurrence at, on, or arising
    from the Premises, the Units and Easements that results or
    would be reasonably likely to result in a material
    noncompliance with any Environmental Laws or any release of
    Hazardous Substances during the Lease Term on or from the
    Premises that has resulted or would be reasonably likely to
    result in personal injury or material property damage, such
    notice to be given promptly after the condition is
    discovered or release or occurrence takes place; (ii) any
    fact, circumstance, condition or occurrence at the Premises
    and the Units that would cause, or would be reasonably
    likely to cause, the Premises, the Units and Easements to be
    subject to any restrictions on ownership, occupancy, use or
    transferability under any Environmental Law; and (iii) any
    pending or threatened Environmental Claim against Lessee or
    any other person or entity arising in connection with their
    occupying or conducting operations on or at the Premises,
    the Units and Easements, such notice to be given promptly
    after such Environmental Claim is commenced or threatened. 
    To the extent possible, all such notices shall describe in
    reasonable detail the nature of the Environmental Claim,
    investigation, condition, incident or occurrence and the
    Lessee's response thereto.  In addition, the Lessee shall
    provide the Owner Participant, the Owner Trustee,  the
    Indenture Trustee and the holders of the Notes with copies
    of all written communications with any Governmental
    Authorities relating to any material non-compliance with
    Environmental Laws or any material Environmental Claim
    simultaneously with the giving or promptly upon receiving
    any such written communications.  The Lessee shall also
    provide such detailed reports of any Environmental Claim as
    may be reasonably requested by the Owner Participant,  the
    Owner Trustee,  the Indenture Trustee and the holders of the
    Notes.

         the transactions described in or contemplated by the
         Operative Agreements;

                (vii)  the payment of the principal or interest

    paragraph (b) above shall not apply to any of the following:

                (i)  in the case of any Tax Indemnitee other
         than a Lender Indemnitee, (A) Taxes imposed by the
         United States federal government, the State of Texas
         (or any Governmental Authority within the State of
         Texas) or the Tax Indemnitee s Home Jurisdiction (as
         hereinafter defined) imposed on or measured by the net
         or gross income or excess profits, capital gains,
         receipts, minimum tax from tax preferences, accumulated
         earnings, personal holding company income, alternative
         minimum taxable income, capital, franchise, excess
         profits, net worth or conduct of business of, or
         succession and estate taxes of, such Tax Indemnitee
         (other than any Taxes which are, or are in the nature
         of, sales (unless included in Equipment Cost), use,
         value added (other than value added Taxes in the nature
         of net or gross income Taxes rather than sales or use
         Taxes), rental, license, ad valorem or property
         Taxes)(collectively "Income Taxes") and (B) Income
         Taxes imposed by any taxing authority other than the
         United States federal government, or the State of Texas
         (or any Governmental Authority within the State of
         Texas) or the Tax Indemnitee s Home Jurisdiction;
         provided, that Income Taxes imposed by a jurisdiction
         described in clause (B) of this Section 7.1(c)(i) shall
         be subject to indemnification if (w) the Units or any
         part thereof are operated, registered, located, present
         or used within such jurisdiction, (x) a Lessee Person
         is present or conducts activities within such
         jurisdiction, (y) a Lessee Person makes, or is deemed
         to make, payments from or through such jurisdiction, or
         (z) any security interest, filing or collateral
         contemplated by the Operative Agreements is present,
         perfected, exists or occurs within such jurisdiction
         and, in any case described in clauses (w) through (z),
         such event or occurrence causes the transactions
         contemplated by the Operative Agreements to be subject
         to Income Tax in such jurisdiction (and if so subject
         to such Income Taxes, the portion of the Tax
         Indemnitee s Income Taxes payable to such jurisdiction
         which shall be subject to indemnification pursuant to
         this Section 7.1 shall be determined as if the sole
         connection of the Tax Indemnitee with such jurisdiction
         had been the transactions contemplated by the Operative
         Agreements).  Notwithstanding the foregoing, the
         provisions of this Section 7.1(c)(i) and each other
         exclusion contained in Section 7.1(c) relating to
         income Taxes shall not be interpreted to exclude any
         amount necessary to make any payment under the
         Operative Agreements, otherwise required to be made on
         an After-Tax Basis, to be made on an After-Tax Basis. 
         For purposes of this Section 7.1(c)(i), the term  Tax
         Indemnitee s Home Jurisdiction  shall mean the State of
         California (or any Governmental Authority within the
         State of California), provided, that if Security
         Pacific Leasing Corporation (or any Affiliate) or any
         transferee or subsequent transferee of Security Pacific
         Leasing Corporation (or an Affiliate) transfers some or
         all of its interest in the Units, the Lease, the Trust
         Estate, or any other interest or obligations arising
         under the Operative Agreements to another Owner
         Participant pursuant to the terms of this Agreement,
         the term "Tax Indemnitee's Home Jurisdiction" shall
         mean the state in which such transferee (or the
         applicable subsequent transferee) is treated as
         maintaining its principal place of business or
         headquarters (and any Governmental Authority within
         such state);

                (ii) in the case of a Lender Indemnitee, (A)
         Taxes imposed by the United States federal governmental
         or the Lender Indemnitee s Home Jurisdiction (as
         hereinafter defined) on or measured by the net or gross
         income or excess profits, capital gains, receipts,
         minimum tax from tax preferences, accumulated earnings,
         personal holding company income, alternative minimum
         taxable income, capital, franchise, excess profits, net
         worth or conduct of business of, or succession and
         estate taxes of, such Lender Indemnitee, other than any
         such Taxes which are, or are in the nature of, sales,
         use, value added, rental, license, ad valorem or
         property Taxes, (collectively, "Income Taxes") and (B)
         Income Taxes imposed by any taxing authority other than
         the United States federal government or the Lender
         Indemnitee s Home Jurisdiction; provided that Income
         Taxes imposed by a jurisdiction described in clause (B)
         of this Section 7.1(c) (ii) shall be subject to
         indemnification if (w) the Units or any part thereof,
         are operated, registered, located, present, or used
         within such jurisdiction, (x) a Lessee Person, or any
         other Tax Indemnitee, is present or conducts activities
         within such jurisdiction, (y) a Lessee Person, or the
         Owner Trustee or Owner Participant, makes, or is deemed
         to make, payments from or through such jurisdiction, or
         (z) any security interest, filing or collateral
         contemplated by the Operative Agreements is present,
         perfected, exists or occurs within such jurisdiction,
         and in any case described in clauses (w) through (z),
         such event or occurrence causes the transactions
         contemplated by the Operative Agreements to be subject
         to Income Tax in such jurisdiction (determined without
         taking into account any other contacts that the Lender
         Indemnitee may have with such jurisdiction) and if so
         subject to such Income Taxes, the portion of the Lender
         Indemnitee s Income Taxes payable to such jurisdiction
         which shall be subject to indemnification pursuant to
         this Section 7.1 shall be determined as if the sole
         connection of the Lender Indemnitee with such
         jurisdiction had been the transactions contemplated by
         the Operative Agreements.  Notwithstanding the
         foregoing, the provisions of this clause (ii) relating
         to Income Taxes shall not exclude from the indemnity
         described in this Section 7.1 any Taxes for which the
         Lessee would be required to indemnify a Lender
         Indemnitee so that any payment under the Operative
         Agreements, otherwise required to be made on an After-
         Tax Basis, is made on an After-Tax Basis.  (For
         purposes of this Section 7.1(c)(ii), the term  Lender
         Indemnitee s Home Jurisdiction  shall mean the State of
         New York, New York City or Germany (or any governmental
         authority within the State of New York, New York City
         or Germany), provided that if the Lender Indemnitee
         transfers all or a portion of its interest in the Note
         or the Construction Advances in accordance with the
         terms of this Agreement, the term  Lender Indemnitee s
         Home Jurisdiction  shall be modified to reflect the
         location within the United States in which the Note or
         Construction Advance is maintained as an asset and the
         jurisdiction under the laws of which the transferee
         Lender Indemnitee has been formed.)

                (iii) in the case of a Tax Indemnitee other than
         a Lender Indemnitee, Taxes arising out of or measured
         by acts, omissions, events or periods of time (or any
         combination of the foregoing) which occur after (and
         are not attributable to acts, omissions or events
         occurring contemporaneously with or prior to) (1) the
         payment in full of all amounts payable by the Lessee
         pursuant to and in accordance with the Operative
         Agreements and (2) the earlier of (x) the expiration of
         the Lease Term and return of the Units in accordance
         with the return provisions of the Lease and (y) the
         termination of the Lease in accordance with the
         applicable provisions of the Lease and return or
         disposition of the Units in accordance with the Lease,
         except that, notwithstanding anything to the contrary,
         Taxes incurred in connection with the exercise of any
         remedies following the occurrence and continuance of a
         Lease Event of Default shall not be included in this
         Section 7.1(c)(iii);

                (iv) in the case of a Lender Indemnitee, Taxes
         imposed on such Lender Indemnitee with respect to any
         period commencing after the date of the payment in full
         of the Construction Advances and the Notes and all
         amounts due to the Construction Lender, the Note
         Purchaser and each holder of a Note pursuant to the
         Operative Agreements, except that Taxes related to
         events occurring or matters arising prior to or
         simultaneously with such date shall not be excluded
         from the indemnity provided for in this Section 7.1 by
         reason of this Section 7.1(c)(iv);

                (v) in the case of a Tax Indemnitee other than a
         Lender Indemnitee, Taxes imposed that would not have
         been imposed but for any act or omission of such Tax
         Indemnitee not contemplated by the Operative
         Agreements, including, without limitation, the willful
         misconduct or gross negligence of such Tax Indemnitee
         (other than any act, omission, gross negligence or
         willful misconduct not actually committed by but
         instead imputed to such Indemnitee by reason of such
         Tax Indemnitee's participation in the transactions
         contemplated by the Operative Agreements and entering
         into the Operative Agreements);

                (vi) in the case of a Lender Indemnitee, Taxes
         imposed on such Lender Indemnitee that would not have
         been imposed but for the gross negligence or willful
         misconduct of such Lender Indemnitee (other than any
         gross negligence or willful misconduct not actually
         committed by such Lender Indemnitee, but imputed to
         such Lender Indemnitee by reason of (y) the acts or
         omissions of a Lessee Person or any other Tax
         Indemnitee, or (z) such Lender Indemnitee s
         participation in the transactions contemplated by the
         Operative Agreements and entering into the Operative
         Agreements);

                (vii) in the case of a Tax Indemnitee other than
         a Lender Indemnitee, Taxes imposed on any Tax
         Indemnitee or any successor, assign or Affiliate
         thereof which became payable by reason of (A) any
         voluntary transfer, assignment, sale or other
         disposition ("Transfer") by such Tax Indemnitee
         subsequent to the applicable Purchase Date, of any
         interest in some or all of the Units, the Lease, its
         interest in the Trust Estate, or any other interest or
         obligations arising under the Operative Agreements,
         other than (y) Taxes that result from Transfers which
         occur as a result of the exercise of remedies after a
         Lease Event of Default has occurred and is continuing
         or (z) Taxes (other than Taxes on net income, Taxes of
         a similar nature or Taxes imposed in lieu of the
         foregoing) that result from any Transfer pursuant to
         the terms of the Lease at the request or option of the
         Lessee (including the Lessee's exercise of the option
         granted pursuant to Section 22 of the Lease); or (B)
         any involuntary Transfer by such Tax Indemnitee of any
         interest in the Units, the Lease, or any interests or
         obligations arising under the Operative Agreements
         resulting from any bankruptcy or other proceeding for
         relief of debtors in which such Tax Indemnitee is the
         debtor or any foreclosure by a creditor of such Tax
         Indemnitee other than any such Transfer following the
         occurrence and continuance of a Lease Event of Default;

                (viii) in the case of a Lender Indemnitee, Taxes
         imposed on such Lender Indemnitee which become payable
         by reason of any voluntary or involuntary transfer or
         disposition by such Lender Indemnitee of its interest
         in the Construction Loan Advances or the Notes other
         than (y) Taxes imposed under Section 4975 of the Code
         that would not have been imposed if the representation
         made by the Owner Participant in Section 3.4(i) had
         been true and correct at the time made, and (z) any
         such Taxes that result from transfers or dispositions
         which occur after a Lease Event of Default has occurred
         and is continuing; provided, however, the provisions of
         this clause (viii) shall not exclude from the indemnity
         described in this Section 7.1 any Taxes for which the
         Lessee would be required to indemnify a Lender
         Indemnitee so that any payment under the Operative
         Agreements, otherwise required to be made on an After-
         Tax Basis, is made on an After-Tax Basis;
         
                (ix)  Taxes imposed on or with respect to or
         payable by the Owner Trustee or the Indenture Trustee
         based on, measured by or imposed with respect to any
         fees paid to or accruable by the Owner Trustee or the
         Indenture Trustee, as the case may be, in its capacity
         as Owner Trustee or the Indenture Trustee, as the case
         may be;

                (x) in the case of a Tax Indemnitee other than a
         Lender Indemnitee, Taxes which have been included in
         Lessor's Cost to the extent actually paid on or before
         the Lease Commencement Date;

                (xi)  Taxes imposed upon the Owner Participant
         for which the Lessee is obligated to indemnify the
         Owner Participant pursuant to the Tax Indemnity
         Agreement;

                (xii)  Taxes imposed against a transferee (or
         subsequent transferee) of an original Tax Indemnitee to
         the extent of the excess of such Taxes over the amount
         of such Taxes which would have been imposed against the
         original Tax Indemnitee had there not been a transfer
         by such original Tax Indemnitee of its interest in the
         Units, the Lease, its interest in the Trust Estate, the
         Notes, the Construction Advances or any other interest
         or obligation arising under the Operative Agreements;
         provided, however, that this subparagraph (xii) shall
         not apply (A) to any transfer following the occurrence
         and continuance of a Lease Event of Default (or, in the
         case of a transferee or subsequent transferee of a
         Lender Indemnitee, a Transfer which occurs while a
         payment then due under the Indenture has not been
         paid), (B) in determining amounts necessary to make
         payments on an After-Tax Basis or (C) Taxes imposed
         under Section 4975 of the Code that would not have been
         imposed if the representation made by the Owner
         Participant in Section 3.4(i) had been true and correct
         at the time made;

                (xiii) in the case of a Tax Indemnitee other
         than a Lender Indemnitee, Taxes resulting from any
         Transfer by a Tax Indemnitee of all or any portion of
         its interest in the Lease or any Unit to the extent of
         the excess of such Taxes over the amount of such Taxes
         that would have been imposed had there been no such
         disposition; and

                (xiv)  any interest, penalties or additions to
         tax of a Tax Indemnitee attributable to a failure by
         such Tax Indemnitee to file when due any report or
         return required by any taxing authority or to a failure
         by the Lessor to pay or remit any Tax when due in
         either case unless caused by the Lessee's failure to
         prepare returns, provide information or otherwise meet
         its obligations under the Operative Agreements.

         (d)    Withholding Taxes.  Notwithstanding any of the
    exclusions set forth in paragraph (c) to the contrary, in
    the case of any withholding Taxes imposed or other
    deductions on the Lessee's payment of Rent or on the payment
    by or on behalf of the Lessor of principal, interest or
    Premium, if any, on the Note or on any amounts paid pursuant
    to the Indenture or the Construction Loan Agreement, the
    Lessee shall make such additional payments as will be
    sufficient such that after the payment of such withholdings
    and deductions there will be available sufficient amounts to
    pay all Rent amounts otherwise payable hereunder or under
    the Lease, and all principal, interest and Premium, if any,
    on the Note or on any amounts paid pursuant to the Indenture
    or the Construction Loan Agreement, subject to the Lessee's
    right to recover from the Owner Participant any of such
    amounts withheld from Lessee s payment of Rent as a result
    of the Owner Participant or any Affiliate thereof, being
    other than a U.S. Person, for which the Owner Participant
    agrees to pay the Lessee promptly upon demand.

         (e)    Payments to the Lessee.

                (i)  If any Tax Indemnitee actually shall
         realize a net Tax benefit with respect to a Tax not
         indemnifiable hereunder as a result of any Taxes paid
         or indemnified against by the Lessee under this Section
         7.1 (whether by way of deduction, credit, allocation or
         apportionment or otherwise), which benefit was not
         previously taken into account in determining the amount
         of the Lessee's payment to such Tax Indemnitee, such
         Tax Indemnitee shall pay to the Lessee an amount, on an
         After-Tax Basis, equal to the amount of such net Tax
         benefit attributable to the payment being made to the
         Lessee hereunder; provided, however, that if, and so
         long as, a Lease Event of Default shall have occurred
         and be continuing, and, in the case of a Lender
         Indemnitee, any payment then due to such Lender
         Indemnitee under the Operative Agreements has not been
         paid, the Tax Indemnitee may hold such amount for the
         benefit of the Lessee and shall pay such amount to the
         Lessee promptly following the date on which the Lease
         Event of Default is no longer continuing and, in the
         case of a Lender Indemnitee, such payment to such
         Lender Indemnitee has been made; provided further,
         however, that no Tax Indemnitee shall be required to
         pay to the Lessee any Tax benefit to the extent such
         benefit (determined without regard to the reverse
         gross-up amount) exceeds the indemnity received by such
         Tax Indemnitee (determined without regard to the gross-
         up amount), with such excess to be carried over and
         applied against any future obligation of the Lessee to
         indemnify such Tax Indemnitee under the Operative
         Agreements.  In the case of a Lender Indemnitee, such
         Lender Indemnitee may determine in its sole discretion
         whether to claim a Tax credit as distinguished from a
         Tax deduction for any Tax and such treatment shall be
         applied for purposes of determining the amount of such
         Tax benefit. If such Tax benefit is thereafter lost,
         the additional Tax payable shall be treated as a Tax
         indemnifiable hereunder without regard to the
         exclusions set forth in Section 7.1(c) except if, and
         to the extent, such loss results solely from such Tax
         Indemnitee's gross negligence or willful misconduct.

                (ii)  Upon receipt by a Tax Indemnitee of a
         refund or credit of all or part of any Taxes paid or
         indemnified against by the Lessee, which refund or
         credit was not previously taken into account in
         determining the amount of the Lessee's payment to Tax
         Indemnitee, such Tax Indemnitee shall pay to the
         Lessee, on an After-Tax Basis,  an amount equal to the
         amount of such refund plus any interest received by or
         credited to such Tax Indemnitee with respect to such
         refund; provided that if, and so long as, a Lease Event
         of default shall have occurred and be continuing, and,
         in the case of a Lender Indemnitee, any payment to such
         Lender Indemnitee under the Operative Agreements then
         due has not been paid, the Tax Indemnitee may hold such
         amount for the benefit of the Lessee and shall pay such
         amount to the Lessee promptly following the date on
         which the Lease Event of Default is no longer
         continuing and, in the case of a Lender Indemnitee,
         such payment has been made.  If it is later determined
         that the Tax Indemnitee was not entitled to such refund
         or credit, the portion of such refund that is repaid,
         recaptured or disallowed will be treated as a Tax
         indemnifiable hereunder without regard to the
         exclusions set forth in Section 7.1(c) except if, and
         to the extent, such loss, recapture or disallowance
         results solely from such Tax Indemnitee s gross
         negligence or willful misconduct.

                (iii)  The Tax Indemnitee will, at the Lessee's
         expense, pursue refunds and Tax benefits that would
         result in any such payments to the Lessee, but only if
         (x) the Tax Indemnitee has been notified in writing by
         the Lessee that such refunds or Tax benefits are
         available, and (y) in the case of a Lender Indemnitee,
         the pursuit of such refund or Tax benefit shall not, in
         the sole discretion of such Lender Indemnitee,
         exercised in good faith, result in any adverse
         consequence to such Lender Indemnitee.


         (f)    Procedures.  Any amount payable to a Tax
    Indemnitee pursuant to paragraph (b) shall be paid within 30
    days after receipt of a written demand therefor from such
    Tax Indemnitee accompanied by a written statement describing
    in reasonable detail the basis for such indemnity and the
    computation of the amount so payable, provided that such
    amount need not be paid prior to the later of (i) the date
    on which such Taxes are due or (ii) in the case of amounts
    which are being contested pursuant to paragraph (g) hereof
    and which are not required to be paid under applicable law,
    the time such contest (including all appeals permitted
    hereunder) is finally resolved, provided, further, that with
    respect to Taxes of a recurring nature, the Tax Indemnitee
    shall only be required to provide one such written notice. 
    Any amount payable to the Lessee pursuant to paragraph (e)
    shall be paid within 30 days of the day on which a return is
    filed reflecting such Tax benefit or, in the case of a
    refund, promptly after the Tax Indemnitee actually receives
    a refund giving rise to a payment under paragraph (e), and
    shall be accompanied by a written statement by the Tax
    Indemnitee setting forth in reasonable detail the basis for
    computing the amount of such payment.  Within 30 days
    following the Lessee's receipt of any computation from the
    Tax Indemnitee, the Lessee may request that a nationally
    recognized accounting firm selected by the Tax Indemnitee,
    and reasonably acceptable to the Lessee, determine whether
    such computations (but not any matters of interpretation of
    law or the Operative Agreements) are correct.  Such
    accounting firm shall be requested to make the determination
    contemplated by this paragraph (f) within 30 days of its
    selection.  In the event such accounting firm shall
    determine that such computations are incorrect, then such
    firm shall determine what it believes to be the correct
    computations.  The Tax Indemnitee shall cooperate with such
    accounting firm and supply it with all information necessary
    to permit it to accomplish such determination.  The
    computations of such accounting firm shall be final, binding
    and conclusive upon the parties and the Lessee shall not
    have any right to inspect the books, records or tax returns
    of the Tax Indemnitee to verify such computation or for any
    other purpose.  All fees and expenses of the accounting firm
    payable under this Section 7.1(f) shall be borne by the
    Lessee, except that if such accounting firm's computation
    shall result in a decrease in the amount due from the Lessee
    or an increase in the amount owing to the Lessee by more
    than the greater of 5% of the Tax Indemnitee's computation
    or $10,000, then the Tax Indemnitee shall bear the cost of
    such accounting firm.

         (g)    Contest.  If any claim shall be made against any
    Tax Indemnitee or if any proceeding shall be commenced
    against any Tax Indemnitee (including a written notice of
    such proceeding) for any Tax as to which the Lessee may have
    an indemnity obligation, or if any Tax Indemnitee shall
    determine that any Tax as to which the Lessee may have an
    indemnity obligation may be payable, such Tax Indemnitee
    shall promptly notify the Lessee in writing and shall not
    take any action with respect to such claim, proceeding or
    Tax without the consent of the Lessee for 30 days after
    receipt of such notice by the Lessee unless the failure to
    take action could result in the imposition of penalties or
    fines or material danger of sale, forfeiture or loss of, or
    the creation of any Lien on, the Units or any portion
    thereof or interest therein; provided, however, that any
    failure to provide such notice shall not relieve the Lessee
    of any obligation to indemnify any Tax Indemnitee hereunder
    except to the extent such failure materially impairs the
    defense of such claim and such failure did not result from
    the Lessee's failure to provide information, file reports or
    otherwise fulfill the requirements of the Operative
    Agreements; provided, further, however, that if such Tax
    Indemnitee shall be required by law or regulation to take
    action with respect to any such claim, proceeding or Tax
    prior to the end of such 30 day period such Tax Indemnitee
    shall, in such notice to the Lessee, so inform the Lessee
    and such Tax Indemnitee shall not take any action with
    respect to such claim, proceeding or Tax without the consent
    of the Lessee before the date on which such Tax Indemnitee
    shall be required to take action.  If, within 30 days after
    its receipt of such notice (or the shorter period referred
    to in the preceding sentence), the Lessee shall request in
    writing that such Tax Indemnitee contest the imposition of
    such Tax, the Tax Indemnitee shall, at the expense of the
    Lessee, in good faith contest (including by pursuit of
    appeals other than appeals to the United States Supreme
    Court), and shall not settle without the Lessee's written
    consent (such consent not to be unreasonably withheld, in
    good faith, based solely on the merits of the claim at
    issue), or if such contest does not involve a claim for
    Income Taxes or Taxes imposed by way of withholding, the Tax
    Indemnitee shall allow the Lessee to contest the validity,
    applicability or amount of such Tax in the Lessee's own
    name, or if required by law, in the Tax Indemnitee's name,
    by, in the sole discretion of the Person conducting such
    contest:

                (i)  resisting payment thereof;

                (ii)  not paying the same except under protest,
         if protest shall be necessary and proper; or

                (iii)  if payment shall be made, using
         reasonable efforts to obtain a refund thereof in
         appropriate administrative and judicial proceedings;

    provided, however, that in no event shall such Tax
    Indemnitee be required to contest (or permit the Lessee to
    contest) the imposition of any Tax for which the Lessee may
    be obligated unless:  (t) no Lease Default or Lease Event of
    Default shall have occurred and be continuing, (u) in the
    case of Income Taxes or withholding Taxes indemnifiable
    hereunder, (1) the amount of the claim and all future
    related claims exceeds $100,000 and (2) the Lessee shall
    have delivered to the Tax Indemnitee an opinion of tax
    counsel chosen by the Lessee and reasonably acceptable to
    the Tax Indemnitee to the effect that there is a Reasonable
    Basis to contest such claim and, in the case of an appeal of
    an adverse judicial decision, a reasonable basis to appeal
    such decision, (v) in the case of any contest conducted by
    the Lessee, the Lessee shall have acknowledged in writing
    its liability hereunder if the contest is unsuccessful, (w)
    the Lessee shall have agreed to pay such Tax Indemnitee all
    costs and expenses that such Tax Indemnitee shall incur in
    connection with the contest of such claim (including all
    reasonable legal and accounting fees and disbursements), (x)
    the action to be taken will not result in any material
    danger of sale, forfeiture or loss of, or the creation of
    any Lien on, the Units or any portion thereof or interest
    therein, (y) if such contest shall involve payment of the
    claim, the Lessee shall advance the amount thereof, plus
    interest, penalties and additions to Tax with respect
    thereto, to such Tax Indemnitee on an interest-free basis
    and on an after-tax basis,  and (z) the subject matter of
    the claim shall not be of a continuing nature which has been
    previously decided by a court of competent jurisdiction
    pursuant to the contest provisions of this Section 7.1(g)
    unless there shall have been a change in facts or law after
    the date with respect to which such previous contest shall
    have been decided, and the Tax Indemnitee shall have
    received, at Lessee s expense, an opinion of independent tax
    counsel chosen by the Lessee and reasonably acceptable to
    the Tax Indemnitee that as a result of such change in facts
    or law it is more likely than not that such contest will
    prevail.  For purposes of the preceding sentence, a
     Reasonable Basis  for a position shall exist if tax counsel
    may properly advise reporting such position on a tax return
    in accordance with ABA Formal Opinion 85-352 issued by the
    Standing Committee on Ethics and Professional Responsibility
    of the American Bar Association.  The Tax Indemnitee shall
    consult in good faith with the Lessee regarding the conduct
    of any contest controlled by such Tax Indemnitee and the
    Lessee shall consult in good faith with the Tax Indemnitee
    regarding the conduct of any contest controlled by the
    Lessee.  Notwithstanding the above, a Tax Indemnitee may
    settle and will not be required to contest the imposition of
    any Taxes if such Tax Indemnitee shall waive its right to
    indemnity with respect to such Taxes and any future and
    logically related Taxes unless, with respect to such future
    Taxes,  the facts or law with respect thereto change in a
    manner which would render a new contest of such Taxes
    reasonable.

         (h)    Reports.  In the event any reports with respect
    to Taxes are required to be made, the Lessee will either
    prepare and file such reports (and in the case of reports
    which are required to be filed on the basis of individual
    Units, such reports shall be prepared and filed in such
    manner as to show as required the interests of each Tax
    Indemnitee in such Unit) or, (x) if it shall not be
    permitted to file the same, it will notify each Tax
    Indemnitee of such reporting requirements, prepare such
    reports in such manner as shall be reasonably satisfactory
    to each Tax Indemnitee and deliver the same to each Tax
    Indemnitee within a reasonable period prior to the date the
    same is to be filed or (y) if it shall not possess the
    information required to so prepare and file (and such
    information is of the type which the Tax Indemnitee could
    reasonably be expected to possess and which is of the type
    which the Lessee and its Affiliates would not reasonably be
    expected to possess) it shall request such information from
    the Tax Indemnitee, which Tax Indemnitee will cooperate with
    the Lessee in good faith to provide such information, if
    within the possession of such Tax Indemnitee, or if not
    within its possession, to obtain (at the Lessee's expense)
    such information; it being understood that the ultimate
    responsibility for obtaining such information not in the
    possession of the Tax Indemnitee shall be that of the
    Lessee.

    7.2  General Indemnification and Waiver of Certain Claims.

         (a)    Claims Defined.  For the purposes of this
    Section 7.2,  Claims  shall mean any and all costs, expenses

    penalties, proceedings, actions or suits or claims of
    whatsoever kind or nature (whether or not on the basis of
    negligence, strict or absolute liability or liability in
    tort) which may be imposed on, incurred by, suffered by, or
    asserted against an Indemnified Person or any Unit or any
    other portion of the Trust Estate and, except as otherwise
    expressly provided in this Section 7.2, shall include, but

    capacity and as Indenture Trustee), the Construction Loan
    Agent, the Construction Lenders, and the holders of Notes.

    Indemnified Person on an After-Tax Basis against Claims
    relating to, resulting from or arising out of the Units, any
    of the property constituting a part of the Trust Estate, the

         of the Lessee or Bayer);

                (vi)   the imposition of any Lien on any Unit

         (d)    Claims Excluded.  The following are excluded
    from the agreement to indemnify under this Section 7.2:

                (i)     Claims with respect to any Unit to the
         extent attributable to acts or events occurring in
         connection with and after (and not attributable to
         events having occurred or conditions existing prior to)
         (A) in the case of the consummation by the Lessee of a
         purchase option with respect to all of the Units under
         Section 22 of the Lease, or the payment of Termination
         Value by the Lessee in respect of Proposed Terminated
         Units under Section 10.2 of the Lease, or the

         termination of the Lease or the expiration of the Lease
         Term thereof, (y) the return of such Unit to the Owner
         Trustee in accordance with the terms of the Lease (it
         being understood that, so long as any Unit is in
         storage as provided in Section 6.3 of the Lease, the
         date of return thereof for the purpose of this Clause
         (i)(B)(y) shall be the end of the last day of such
         storage period), and (z) the payment in full of the
         principal of, Premium, if any, and interest on the

         necessary to indemnify Claims on an After-Tax Basis),
         or any cost or expense of contesting any such Taxes
         whether or not the Lessee is required to indemnify
         therefor under Section 7.1 hereof or the Tax Indemnity
         Agreement, the Lessee's entire obligation with respect
         to Claims which are Taxes under Section 4975 of the
         Code and to Taxes and losses of tax benefits being
         fully set out in such Section 7.1 or the Tax Indemnity
         Agreement; 

                (iii)  with respect to any particular
         Indemnified Person and only as to such Indemnified
         Person, Claims to the extent attributable to the gross
         negligence or wilful misconduct (other than any gross
         negligence or wilful misconduct imputed as a matter of
         law to such Indemnified Person solely by reason of its
         participation in the transactions and entering into the
         Operative Agreements, its interest in the Units or the
         acts or omissions of the Lessee or Bayer) of, or the
         falsity or inaccuracy of any representation or warranty
         of, or any breach of any covenant of, such Indemnified
         Person; and

                (iv)  Claims attributable to (A) any voluntary
         transfer, assignment or other disposition ( Transfer )
         by such Indemnified Person subsequent to the applicable
         Purchase Date, of any interest in some or all of the
         Units, any of the property constituting the Trust
         Estate, the Lease, its interest in the Trust Estate,
         the Notes, the Construction Advances or any other
         interests or obligations arising  under the Operative
         Agreements other than (x) Transfers which occur as a
         result of the exercise of remedies after a Lease Event
         of Default has occurred and is continuing,  (y) any
         Transfer pursuant to the terms of the Lease at the
         request or option of the Lessee (including the Lessee's
         exercise of the option granted pursuant to Section 22
         of the Lease), or (z) any Claim under ERISA that would
         not have been made if the representation made by the
         Owner Participant in Section 3.4(i) had been true and
         correct when made or (B) any involuntary Transfer by
         such Indemnified Person of any interest in the Units,
         any of the property constituting the Trust Estate, the
         Lease, the Notes, the Construction Advances or any
         interests or obligations arising under the Operative
         Agreements resulting from any bankruptcy or other
         proceeding for relief of debtors in which such
         Indemnified Person is the debtor or any foreclosure by
         a creditor of the Indemnified Person other than (y) any
         such Transfer following the occurrence and continuance
         of a Lease Event of Default, or (z) any Claim under
         ERISA that would not have been made if the
         representation made by the Owner Participant in Section
         3.4(i) had been true and correct when made.

         (e)    Insured Claims.  In the case of any Claim
    indemnified by the Lessee hereunder which is covered by a
    policy of insurance maintained by the Lessee pursuant to
    Section 12 of the Lease or otherwise, each Indemnified
    Person agrees, at Lessee's cost and expense, to provide
    reasonable cooperation to the insurers in the exercise of
    their rights to investigate, defend or compromise such Claim
    as may be required to retain the benefits of such insurance
    with respect to such Claim.

         (f)    Claims Procedure.  An Indemnified Person shall,
    after obtaining actual knowledge thereof, promptly notify
    the Lessee of any Claim as to which indemnification is
    sought (unless the Lessee theretofore has notified such
    Indemnified Person of such Claim); provided, however, that
    the failure to give such notice shall not release the Lessee
    from any of its obligations under this Section 7, except to
    the extent that failure to give notice of any action, suit
    or proceeding against such Indemnified Person shall
    materially and substantially prejudice the Lessee's ability
    to defend such Claim and such failure arises out of or is
    caused by the misconduct or negligence of such Indemnified
    Person, provided that, for purposes of this sentence,
    whenever (but only prior to the Lease Term Commencement
    Date) Bayerische, in its capacity as a Construction Lender,
    is an Indemnified Person, such Indemnified Person shall be
    deemed to have actual knowledge of a Claim only to the
    extent that both such Indemnified Person and the
    Construction Loan Agent have actual knowledge of such claim. 
    Subject to the provisions of the following paragraph, the
    Lessee shall at its sole cost and expense be entitled to
    control, and shall assume full responsibility for, the
    defense of such Claim; provided that the Lessee shall keep
    the Indemnified Person which is the subject of such
    proceeding fully apprised of the status of such proceeding
    and shall provide such Indemnified Person with all
    information with respect to such proceeding as such
    Indemnified Person shall reasonably request.

         Notwithstanding any of the foregoing to the contrary,
    no Lessee shall be entitled to control and assume
    responsibility for the defense of such Claim if (1) a Lease
    Event of Default shall have occurred and be continuing and
    the Indemnified Person notifies the Lessee that it is no
    longer permitted to control the defense of such Claim, (2)
    there exists an imminent risk of sale, forfeiture or loss of
    any Unit or any other portion of the Trust Estate or such
    proceeding will involve any material danger of the sale,
    forfeiture or loss of, or the creation of any Lien (other
    than any Permitted Lien) on, any Unit or any other portion
    of the Trust Estate, (3) the amounts involved, in the
    reasonable opinion of such Indemnified Person, are likely to
    have a materially adverse effect on the business, taken as a
    whole, of such Indemnified Person (other than the ownership,
    leasing and financing of the Units), (4) in the reasonable
    opinion of such Indemnified Person, there exists an actual
    or potential material conflict of interest such that it is
    advisable for such Indemnified Person to retain control of
    such proceeding, (5) the Lessee has not acknowledged its
    liability to the Indemnified Person with respect to such
    Claim (except to the extent that thereafter any judicial
    determination or settlement establishes that the act,
    omission or event giving rise to such Claim was not
    indemnifiable under this Section 7.2) or (6) in the
    reasonable opinion of such Indemnified Person such Claim
    involves the risk of criminal sanctions or liability to such
    Indemnified Person.  In the circumstances described in
    clauses (1) through (6), the Indemnified Person shall be
    entitled to control and assume responsibility for the
    defense of such claim or liability at the cost and expense
    of the Lessee.  Unless a Lease Event of Default has occurred
    and is continuing, the Indemnified Person shall not settle
    or compromise any Claim without the prior consent of the
    Lessee, which consent shall not be unreasonably withheld. 
    In addition, any Indemnified Person, at its own cost and
    expense, may participate in any proceeding controlled by the
    Lessee pursuant to this Section 7.2(f).  The Lessee may in
    any event participate in all such proceedings at its own
    cost and expense.  Nothing contained in this Section 7.2(f)
    shall be deemed to require an Indemnified Person to contest
    any Claim or to assume responsibility for or control of any
    judicial proceeding with respect thereto.

         (g)    Subrogation.  If a Claim indemnified under this
    Section 7.2 is paid in full by the Lessee and/or an insurer
    under a policy of insurance maintained by the Lessee, or if
    payment of the Claim has otherwise been provided for in full
    in a manner reasonably satisfactory to the Indemnified
    Person, the Lessee and/or such insurer, as the case may be,
    shall be subrogated to the extent of such payment (or
    provision) to the rights and remedies of the Indemnified
    Person (other than under insurance policies maintained by
    such Indemnified Person) on whose behalf such Claim was paid
    (or provided for) with respect to the act or event giving
    rise to such Claim.  So long as no Lease Default or Lease
    Event of Default shall have occurred and be continuing,
    should an Indemnified Person receive any refund, in whole or
    in part, with respect to any Claim paid by the Lessee
    hereunder, it shall promptly pay over the amount refunded
    (but not in excess of the amount the Lessee or any of its
    insurers has paid in respect of such Claim paid or payable
    by such Indemnified Person on account of such refund) to the
    Lessee.

         (h)    Waiver of Certain Claims.  The Lessee hereby
    waives and releases any Claim now or hereafter existing
    against any Indemnified Person arising out of death or
    personal injury to personnel of the Lessee or any of its
    Affiliates or Bayer (including directors, officers,
    employees, agents and servants), loss or damage to property
    of the Lessee or its Affiliates or Bayer, or the loss of use
    of any property of Lessee or its Affiliates or Bayer, which
    may result from or arise out of the condition, use or
    operation of the Units during the Lease Term, including,
    without limitation, any latent or patent defect whether or
    not discoverable.

         (i)    No Guaranty.  The general indemnification
    provisions of this Section 7.2 do not constitute a guaranty
    by the Lessee that the principal of, interest on or any
    other amounts payable with respect to the Notes will be
    paid.

SECTION 8       LESSEE'S RIGHTS UNDER THE LEASE

    Each party to this Agreement acknowledges notice of, and
consents in all respects to, the terms of the Lease, and
expressly, severally and as to its own actions only, agrees that
unless a Lease Event of Default has occurred and is continuing,
it shall not take, or cause to be taken, any action contrary to
the Lessee's rights under the Lease, including, without
limitation, the right to possession, use and operation by the
Lessee (or any permitted sublessee) of the Units.

SECTION 9       SPECIAL RIGHTS OF NOTE PURCHASER 

    Notwithstanding any provision to the contrary in this
Agreement, the Indenture or the Notes relating to the manner and
place of payment, all amounts payable to the Note Purchaser with
respect to any Notes held by the Note Purchaser or a nominee for
the Note Purchaser shall be paid by the Indenture Trustee to the
Note Purchaser (without any presentment thereof and without any
notation of the payment being made thereon) by check, duly
mailed, by first-class mail, postage prepaid, or delivered to
such Note Purchaser at the address for payments for such Note
Purchaser or, if a wire transfer to a bank account is designated
opposite such Note Purchaser's name on Schedule 1 or in a written
notice from such Note Purchaser to the Owner Trustee and the
Indenture Trustee, by wire transfer of immediately available
funds to the bank so designated for credit to the account and
marked for attention as so designated, provided that such bank
has facilities for the receipt of a wire transfer, or in any
other manner or to any other address in the United States as may
be designated by such Note Purchaser in a written notice from
such Note Purchaser to the Owner Trustee and the Indenture
Trustee.  In the case of any wire transfer, the Indenture Trustee
will transfer funds from the office of the Indenture Trustee not
later than 2:00 p.m., Wilmington, Delaware time the date any
payment or prepayment of principal, Premium, if any, or interest
on the Notes is due, provided that funds therefor have been
received by the Indenture Trustee in cash or in solvent credits
acceptable to it by 12:00 noon, Wilmington, Delaware time, or if
not so received, the Indenture Trustee shall transfer such funds
promptly upon its receipt of such cash or solvent credits, but no
later than 12:00 noon Wilmington, Delaware time the next Business
Day.  In the event the Indenture Trustee shall fail to make any
such payment as provided in the immediately foregoing sentence
after its receipt of funds by the time specified above, the
Indenture Trustee agrees to compensate the Note holders for loss
of use of funds.  The Note Purchaser agrees that, if the Note
Purchaser shall sell or transfer any Notes, the Note Purchaser
will notify the Indenture Trustee of the name and address of the
transferee and such Note Purchaser will, prior to the delivery of
such Notes, make a notation on such Notes of the date to which
interest has been paid thereon and of the amount of any payments
or prepayments made on account of the principal thereof.
