                                        (hereinafter called the "Executive")

       WHEREAS the Executive is the  Co-Chairman of the Company and is presently
performing his functions for the Company on a full-time basis; and

       WHEREAS it is the mutual desire of the Company and the Executive that the
Executive continue to remain in the employ of the Company; and

       WHEREAS  the  Company  and the  Executive  desire to enter  into a formal
employment agreement,  the whole subject to the terms and conditions hereinafter
set forth.

NOW, THEREFORE,  IN CONSIDERATION OF THE FOREGOING,  THE PARTIES HERETO COVENANT
AND AGREE AS FOLLOWS:

1. The preamble hereto shall form an integral part hereof as if herein set forth
at length.

2. The Executive  agrees to continue in the employ of the Company and to perform
those  functions  for  which  he  is  presently  responsible,  subject  to  such
modifications of said functions and to such directives as may be communicated to
the  Executive  from time to time by the Board of  Directors of the Company (the

the  performance  of his  duties  as they  may from  time to time be  determined
pursuant to the terms of this agreement. The Executive further covenants that he
will  faithfully  perform  those duties which are assigned to him to the best of
his  ability and that he will not engage in any other act of  business,  subject
only  to his  right  to  engage  in  activities  directly  relating  to  passive
investments  by  the  Executive  which  do not  materially  interfere  with  the
Executive's duties and responsibilities pursuant to this agreement.

                                       97

4. During the Term,  the  Executive  shall be nominated by the Company,  at each
annual general meeting of  shareholders  at which the  Executive's  then current
term of office as a director of the Company is to expire,  to sit as a member of
the Board.

5. The Company agrees to pay to the Executive, during the Term, a minimum salary
of Cdn.  $183,000  per annum,  said  amount to be  payable  in equal,  bi-weekly
installments  or  otherwise  as in  accordance  with the  payroll  policy of the
Company,  from time to time,  less such  deductions or amounts to be withheld by
the Company as required by law.

6. In  recognition  of the  significant  contributions  of the  Executive to the
affairs of the Company,  the Company  shall pay to the Executive an annual bonus
(the  "Recognition  Bonus")  in  respect  of each  fiscal  year of the  Company,
commencing with the fiscal year ending December 31, 1997. The Recognition  Bonus
shall not be less than  twenty-five  percent (25%) of the minimum salary paid or
payable to the Executive in respect of such fiscal year. The  Recognition  Bonus
in  respect  of each  fiscal  year  shall be paid to the  Executive  on the next
following day on which an installment  of his minimum  salary is payable,  after
the end of such  fiscal  year (the  "Bonus  Payment  Date").  The  amount of the
Recognition  Bonus  shall  be paid to the  Executive  net of any  deductions  or
amounts to be withheld by the Company as required by law.

7. The  Executive  shall be paid an annual  bonus in respect of each fiscal year
during  the  Term,  in such  amount,  if any,  and at such  time(s)  as shall be
determined at the sole  discretion of the Board.  The amount of such bonus shall
be paid to the Executive net of any  deductions or amounts to be withheld by the
Company as required by law.

following the approval by the Board of the audited  financial  statements of the
Company for the immediately  preceding fiscal year, and may, at any time, review
and at its discretion  adjust,  the amounts of minimum salary and/or Recognition
Bonus which are payable to the Executive;  provided, however, that the amount of
minimum salary payable to the Executive  during any year of the Term shall in no
event be less than the minimum annual salary payable to the Executive during any
previous  year of the Term and the amount of  Recognition  Bonus  payable to the
Executive in respect of any fiscal year of the Company shall in no event be less
than the minimum amount provided for in section 6 hereof.

9. Intentionally deleted.

10.  During the Term,  the Company  shall,  in  addition to any other  insurance
coverage provided to the Executive in his capacity as an officer of the Company,
pay or reimburse to the Executive the cost of the reasonable premiums associated
with a personal life and disability  insurance policy with a minimum coverage of
U.S.  $5,000,000 (or the Canadian  dollar  equivalent  thereof) in term or whole
life insurance, which policy shall be owned by the Executive or his designee.

11. The  Executive  shall be  entitled  to  twenty-five  (25)  business  days of
vacation  per fiscal year,  to be taken at such times and  intervals as shall be
determined by the  Executive,  subject to the  reasonable  business needs of the
Company.  The  vacation  days not used  during  any  fiscal  year,  may,  at the
Executive's  option,  be accumulated  and carried  forward to be used during any
subsequent fiscal year; provided,  however,  that the Executive may not use more
than  forty  (40)  business  days of  vacation  in any  one  fiscal  year.  Upon
termination of the Executive's employment hereunder,  or upon the request of the
Executive at any time, the Company shall pay to the Executive an amount equal to
the number of vacation days  accumulated,  multiplied  with respect to each such
day by the annual  minimum salary which was in effect for the year to which such
vacation day relates;  the parties  hereby  agreeing that any vacation days used
during a fiscal year shall be applied first against vacation days accumulated in
respect  of the  earliest  fiscal  year in  regard  to which  vacation  days are
accumulated and shall  thereafter be applied  against the next following  fiscal
years in regard to which vacation days are accumulated.

12. Subject to the receipt by the Company of all necessary regulatory approvals,
the Company hereby grants to the Executive an irrevocable  option (the "Option")
to purchase from treasury a total of four hundred  thousand  (400,000) Class "A"
shares of the capital of the Company  ("Optimal  Shares") at an option  exercise

and conditions pertaining to the Option are as follows:

       (i)    the Option shall expire on May 5, 2002;

       (ii)   prior to its expiration or earlier  termination in accordance with
              the terms  hereof,  the Option shall be  exercisable  from time to
              time in cumulative  installments  as to all or any of the optioned
              Optimal Shares subject thereto as follows;

              (A)    as and from the date hereof, the Option may be exercised as
                     to fifty percent (50%) of the optioned Optimal Shares;

              (B)    after May 5, 1998,  the Option  may be  exercised  as to an
                     additional   twenty-five  percent  (25%)  of  the  optioned
                     Optimal Shares; and

              (C)    after May 5, 1999,  the Option may be  exercised  as to the
                     balance of the optioned Optimal Shares;

              provided,  however,  that in the event of the  termination  by the
              Company of the Executive's employment, otherwise than by reason of
              termination for cause (as hereinafter in section 16 defined),  the
              Option  shall  thereupon  become  exercisable  as to  all  of  the
              optioned  Optimal  Shares in  respect  of which the Option has not
              already become  exercisable in accordance with clauses (B) and (C)
              of this paragraph (iii), and the provisions of paragraphs (ix) and
              (x) of this section 12 shall have application;

       (iii)  Intentionally deleted;

       (iv)   in  the  event  of  any  subdivision  or   consolidation   of  the
              outstanding  Optimal  Shares at any time after the date hereof and
              prior to the expiration or cancellation of the Option, the Company
              shall  deliver  to the  Executive  at the  time of any  subsequent
              exercise of the Option in  accordance  with the terms  hereof,  in
              lieu of the number of Optimal  Shares to which the  Executive  was
              theretofore  entitled  upon  such  exercise,   but  for  the  same
              aggregate  consideration payable therefor,  such number of Optimal
              Shares  as the  Executive  would  have  held as a  result  of such
              subdivision  or  consolidation  if on the record date  thereof the
              Executive had been the registered  holder of the number of Optimal
              Shares to which the Executive was  theretofore  entitled upon such
              exercise;

       (v)    if at any time after the date  hereof and prior to the  expiration
              or  cancellation  of the Option,  the  outstanding  Optimal Shares
              shall be reclassified, reorganized or otherwise changed, otherwise
              than pursuant to a subdivision or a consolidation  of such shares,
              or the Company shall consolidate, merge or amalgamate with or into
              another corporation (the corporation  resulting or continuing from
              such  consolidation,  merger or amalgamation being in this section
              12 called the  "Successor  Corporation"),  the Executive  shall be
              entitled  to  receive  upon such  exercise  of the  Option  and in
              accordance with the terms hereof,  and shall accept in lieu of the
              number of Optimal  Shares then  subscribed  for,  but for the same
              aggregate  consideration payable therefor, the aggregate number of
              shares of the  appropriate  class and/or other  securities  of the
              Company or the Successor  Corporation  (as the case may be) and/or
              other consideration from the Company or the Successor  Corporation
              (as the case may be) that the  Executive  would have been entitled
              to receive as a result of such reclassification, reorganization or
              other  change  of  shares  or as a result  of such  consolidation,
              merger  or   amalgamation,   if  on  the   record   date  of  such

                                       99
<PAGE>

              reclassification,  reorganization or other change of shares or the
              effective date of such consolidation,  merger or amalgamation,  as
              the case may be, the Executive had been the  registered  holder of
              the  number  of  Optimal   Shares  to  which  the   Executive  was
              immediately theretofore entitled upon such exercise;

       (vi)   the  Option  is  personal  to  the  Executive  and  shall  not  be
              assignable or transferrable,  whether  voluntarily or by operation
              of law,  except by will or by the  applicable  laws of succession,
              nor  shall  the   Option  be   pledged,   hypothecated,   charged,
              transferred,  or otherwise encumbered or disposed of, the whole on
              pain of nullity;

       (vii)  the  granting of the Option  shall not impose upon the Company any
              obligation  to retain the Executive in its employ or as a director
              of the Company;

       (viii) upon the Executive's  employment  being  terminated for cause, the
              Option  or  the   unexercised   portion  thereof  shall  terminate
              forthwith;

       (ix)   upon the Executive's employment with the Company being terminated,
              otherwise  than by reason of death or termination  for cause,  the
              Option or  unexercised  part  thereof  shall be  exercisable  only
              within one hundred and eighty (180) days after such termination or
              prior  to the  expiration  of the  term of the  Option,  whichever
              occurs earlier;

       (x)    if the Executive dies while employed by the Company, the Option or
              unexercised  part  thereof may be  exercised by the person to whom
              the  Option  is  transferred  by  will or the  applicable  laws of
              descent and  distribution and shall be exercisable only within one
              hundred and eighty (180) days after the Executive's death or prior
              to the  expiration  of the term of the  Option,  whichever  occurs
              earlier; and

       (xi)   the Executive (or his personal  representatives or legatees) shall
              have no rights  whatsoever as a  shareholder  in respect of any of
              the  Optimal  Shares  covered  by the  Option  until  the  date of
              issuance  of  a  share   certificate   to  him  (or  his  personal
              representatives  or legatees) for such shares.  Without in any way
              limiting the generality of the foregoing,  no adjustment  shall be
              made for  dividends  or other  rights for which the record date is

16. In addition to any other provisions  contained herein, in the event that, at
any time during the Term or within 12 months  following the  termination  of the
Executive's  employment  for any reason  other than for cause,  an arm's  length
third party shall make a bone fide offer to acquire,  directly or indirectly, by
way of take-over bid (within the meaning ascribed to such term in the Securities
Act  (Ontario)),  merger (by way of  arrangement,  amalgamation or otherwise) or
other similar  procedure,  outstanding  shares of the Company  representing more
than fifty percent (50%) of the votes attaching to all outstanding voting shares
of the Company (such offer being  hereinafter  called an "Offer"),  the exercise
price of all Optimal Share purchase  options,  warrants and rights, if any, held
by the  Executive,  shall,  subject to regulatory  approval,  be reduced to Cdn.
$1.00 in the aggregate and all of such options, warrants and rights shall become
immediately  exercisable  notwithstanding any terms to the contrary set forth in
any agreement or plan pursuant to which any of such options, warrants and rights
have been granted; provided, however, that:

       (i)    in the event that the Offer is a take-over bid:

                     exercise  price and of the  exercise  of any such  options,
                     warrants  and  rights at such  reduced  aggregate  exercise
                     price,  shall be conditional upon such number of securities
                     of the  Company  having  been  tendered  in response to the
                     Offer,  such that the offeror shall be obligated to take up
                     and pay for such securities in accordance with the terms of
                     the Offer;

              (b)    in the event that such  exercise of options,  warrants  and
                     rights at such reduced  exercise price has become effective
                     in accordance  with the  preceding  paragraph  (i)(a),  the
                     Company shall forthwith  thereafter  cause  certificates in
                     respect of the Optimal  Shares  which are to be issued upon
                     such  exercise  of  options,  warrants  and  rights  to  be
                     delivered  to the  Executive  in order  that  such  Optimal
                     Shares  can  be  tendered  for  sale  pursuant  to  and  in
                     accordance with the terms of the Offer,  the parties hereby
                     agreeing to execute  all such  additional  instruments  and
                     take  all  such  additional  steps  as  may  be  reasonably
                     required in  connection  with the tendering of such Optimal
                     Shares pursuant to the Offer; and

              (c)    in the event that such reduction in such aggregate exercise
                     price and such exercise of options,  warrants and rights at
                     such reduced  exercise  price,  do not become  effective in
                     accordance  with the provisions of the preceding  paragraph
                     (i)(a), such exercise of such options,  warrants and rights
                     shall  be  deemed  not  to  have  occurred,  the  aggregate
                     exercise  price of Cdn.  $1.00 shall be  reimbursed  to the
                     Executive  and any Optimal  Shares  which were to have been
                     issued upon such  exercise of options,  warrants and rights
                     shall  be  deemed   not  to  have  been   issued   and  any
                     certificates in respect thereof shall be cancelled; and

       (ii)   in the event that the Offer is not a take-over bid:

              (a)    the  effectiveness  of such  reduction  in  such  aggregate
                     exercise  price  and  of  the  exercise  of  such  options,
                     warrants and rights at the reduced  exercise  price of Cdn.
                     $1.00,  shall be  conditional  upon the Offer  having  been
                     approved by all  necessary  corporate,  regulatory  and, if
                     required, shareholder approvals;

              (b)    the Company shall forthwith  following the effectiveness of
                     the acceptance of the Offer (which,  by way of example,  in
                     the case of an  arrangement  between  the  offeror  and the
                     Company,  would be  immediately  following  the  filing  of
                     articles of arrangement),  cause certificates in respect of
                     the  Optimal  Shares  which  are  to be  issued  upon  such
                     exercise  of options,  warrants  and rights to be issued to
                     the Executive; and

              (c)    in the event that such reduction in such aggregate exercise
                     price and such exercise of options,  warrants and rights at
                     such reduced  exercise  price,  do not become  effective in
                     accordance  with the provisions of the preceding  paragraph
                     (ii)(a), such exercise of such options, warrants and rights
                     shall  be  deemed  not  to  have  occurred,  the  aggregate
                     exercise  price of Cdn.  $1.00 shall be  reimbursed  to the
                     Executive  and any Optimal  Shares  which were to have been
                     issued upon such  exercise of options,  warrants and rights
                     shall  be  deemed   not  to  have  been   issued   and  any
                     certificates in respect thereof shall be cancelled.

       Provided that the Offer shall have been  accepted in accordance  with its
terms,  if the Offer is a take-over  bid, or that the  proposed  transaction  is
concluded,  in the event that the Offer is a merger or other similar  procedure,
the following additional provisions shall apply:

                                      101
<PAGE>

       (iii)  the  Company  shall  forthwith  thereafter  declare and pay to the
              Executive a bonus in an amount not less than the  aggregate of the
              minimum  annual  salary then being paid to the  Executive  plus an
              amount  (being  twenty-five  percent  (25%) of the  amount of such
              annual salary) equal to the  Recognition  Bonus  corresponding  to
              such minimum annual salary. The amount of such bonus shall be paid
              to the Executive  net of any  deductions or amounts to be withheld
              by the  Company as  required by law but shall not in any way limit
              the  amounts  of  minimum  annual  salary  and  Recognition  Bonus
              otherwise  payable to the  Executive for such fiscal year pursuant
              to sections 5 and 6 hereof; and

       (iv)   the term insurance,  if any, then owned by the Executive for which
              the  Company  is  responsible  for  the  cost of the  premiums  in
              accordance with section 10 shall forthwith thereafter be converted
              to, or  replaced  by a whole life  policy  for the same  insurance
              amount,  which  policy  shall  be owned  by the  Executive  or his
              designee,  and the Company shall pay or reimburse to the Executive
              the entire  cost of the  premium  for such  whole  life  insurance
              policy.

       For the purposes of this agreement, "cause" shall include:

       (A)    the  habitual  neglect or failure  to fulfil  conscientiously  and
              diligently  obligations  assigned  by the  Board or to  carry  out
              lawful orders relating to employment with the Company;

       (B)    habitual  inability to carry out  functions of  employment  due to
              alcohol or drug-related causes; or

       (C)    any materially  dishonest or fraudulent  act relating  directly or
              indirectly to the course of employment.

       In the  event  that  the  Company  is  unable  to  obtain  all  necessary
regulatory  approvals for the reduction to Cdn. $1.00 of the aggregate  exercise
price of all Optimal  Share  purchase  options,  warrants and rights held by the
Executive,  the Company  shall  declare a bonus  payable to the  Executive in an
amount equal to the aggregate  exercise price of all such options,  warrants and
rights  and shall  apply the amount of such bonus  against  the  payment of such
aggregate  exercise price;  provided,  however,  that the  effectiveness  of the
declaration  of such  bonus  shall  be  subject  to the same  conditions  as the
proposed  reduction of such aggregate  exercise  price,  in accordance  with the
foregoing paragraph (i)(a) or (ii)(a), as the case may be, and in the event that
such bonus  declaration  does not become  effective,  any such  exercise of such
options,  warrants and rights shall be deemed not to have occurred,  any Optimal
Shares  which were to have been issued upon such  exercise of options,  warrants
and rights  shall be deemed  not to have been  issued  and any  certificates  in
respect  thereof  shall be  cancelled.  17. In the event that the Company  shall
terminate the  employment of the  Executive,  other than for cause or due to the
death or  Disability  of the  Executive,  or in the  event  that  the  Executive
terminates  his  employment  with the Company  for Good  Reason (as  hereinafter
defined)  within  six  months  following  a Change of  Control  (as  hereinafter
defined) of the Company, the following provisions shall apply:

       (i)    the Company  shall  forthwith  pay to the Executive an amount (the
              "Termination  Payment")  equal to five times the  aggregate of (i)
              the  highest   annual  minimum  salary  paid  or  payable  to  the
              Executive, pursuant to section 5 hereof, during the Term, (ii) the
              highest annual Recognition Bonus paid or payable to the Executive,
              pursuant  to  section  6  hereof,  during  the Term and  (iii) the
              highest annual bonus paid or payable to the Executive, pursuant to
              section 7 hereof, during the Term;

       (ii)   the exercise price of all Optimal Share purchase options, warrants
              and  rights,  if any,  held by the  Executive  shall,  subject  to
              regulatory approval,  be reduced to $1.00 in the aggregate and all
              of such  options,  warrants and rights  shall  become  immediately

                                      102
<PAGE>

              exercisable notwithstanding any terms to the contrary set forth in
              any  agreement  or plan  pursuant  to which  any of such  options,
              warrants and rights have been  granted;  provided,  however,  that
              such share purchase options (but not such share purchase  warrants
              or rights) shall no longer be  exercisable  ninety (90) days after
              the termination of the Executive's employment with the Company;

       (iii)  the term insurance,  if any, then owned by the Executive for which
              the  Company  is  responsible  for  the  cost of the  premiums  in
              accordance  with section 10 shall  forthwith  be converted  to, or
              replaced  by a whole life  policy for the same  insurance  amount,
              which policy shall be owned by the Executive or his designee,  and
              the Company  shall pay or  reimburse to the  Executive  the entire
              cost of the premium for such whole life insurance policy; and

       (iv)   the Company shall forthwith acquire medical insurance coverage for
              the Executive,  which coverage shall provide the Executive and his
              family with health,  life, dental and other insurance  coverage in
              Canada and the United  States which is  equivalent to the coverage
              theretofore  maintained  by the  Company  for the  benefit  of its
              senior  executives  and enjoyed by the  Executive.  Such  coverage
              shall be for a term of five  years  and shall  commence  forthwith
              following the termination of the Executive's employment.

       For the  purposes  hereof,  "Good  Reason"  shall  mean  the  express  or
constructive  demotion of the Executive,  the  diminishment  of his authority or
responsibility  as a  senior  executive  of  the  Company  or a  change  in  the
Executive's  duties or the scope of such duties,  and "Change of Control"  shall
mean the  occurrence  of either (a) the  acquisition  by an arm's  length  third
party, directly or indirectly,  by way of take-over bid, merger or other similar
procedure,  of outstanding  shares of the Company  representing more than thirty
percent  (30%) of the votes  attaching to all  outstanding  voting shares of the
Company,  or (b) one- third or more of the  members of the Board  consisting  of
persons  other  than  Current  Directors  (and for  these  purposes  a  "Current
Director"  shall mean any member of the Board elected at or continuing in office
after, the 1997 annual meeting of shareholders of the Company,  any successor of
a Current Director who has been approved by a majority of the Current  Directors
then on the Board,  and any other person who has been  approved by a majority of
the Current  Directors  then on the Board).  The parties agree that in the event
that the  Company  shall fail to pay or  otherwise  perform its  obligations  in
favour of the  Executive  pursuant to this section 17 and such  obligations  are
successfully  enforced  by the  Executive  following  the  institution  of legal
proceedings,  the Company shall  reimburse to the Executive all of his costs and
expenses  (including legal fees and  disbursements)  which have been incurred by
the Executive in order to enforce such obligations.

18.  In the  event  that the  Company  shall  terminate  the  employment  of the
Executive for cause,  the Executive  shall not be entitled to a notice period or
to any compensation, payment or damages in lieu of notice.

19. If the Executive shall die or shall  voluntarily  resign from his employment
with the  Company  (other  than in the  circumstances  provided  in  section  17
hereof), the Company shall have no further obligation hereunder except to pay to
the  Executive  (or his  succession,  as the case may be) any accrued but unpaid
minimum  salary,  Recognition  Bonus and  statutory  vacation pay, and any bonus
declared (pursuant to section 7) and then unpaid.

20.  In the  event  that the  Company  shall  terminate  the  employment  of the
Executive  due to the  Disability  of the  Executive,  the  Executive  shall  be
entitled to payment of any accrued but unpaid minimum annual salary, Recognition
Bonus and statutory vacation pay, and any bonus declared (pursuant to section 7)
and then unpaid,  as well as his minimum annual salary for a period of 12 months
from the date of notice for termination.

       For the purposes of this agreement, the Executive shall be deemed to have
suffered a Disability when:

                                      103
<PAGE>

       (i)    he has, by reason of physical  or mental  disability,  been unable
              for a  continuous  period of twelve  (12) months to carry on, on a
              full-time   basis,   substantially   all   business   duties   and
              responsibilities  for which he was employed in the same manner and
              to the  same  extent  as such  duties  and  responsibilities  were
              carried  on by  the  Executive  prior  to  the  occurrence  of the
              disability; or

       (ii)   a medical  doctor shall have  certified in writing that, by reason
              of mental or physical  disability,  it is unlikely that he will be
              able,  within  twelve (12)  months,  to resume  carrying  on, on a
              full-time   basis,   substantially   all   business   duties   and
              responsibilities for which he was employed.

21. For the purposes of sections 19 and 20 hereof:

       (i)    accrued  but unpaid  vacation  pay shall be paid to the  Executive
              forthwith  following   termination  of  his  employment  with  the
              Company;

       (ii)   Recognition  Bonus in  respect  of the  fiscal  year in which  the
              Executive's  employment is terminated shall be deemed to accrue on
              a daily  basis  and  shall  be paid to the  Executive  on the next
              following Bonus Payment Date;

       (iii)  any bonus declared (pursuant to section 7) and then unpaid,  which
              is payable in  accordance  with section 19 or 20 hereof,  shall be
              paid  forthwith  following  the  termination  of  the  Executive's
              employment with the Company;

       (iv)   accrued but unpaid minimum  annual  salary,  payable in accordance
              with  section 19 hereof,  shall be paid  forthwith  following  the
              termination of the Executive's employment with the Company; and

       (v)    minimum annual salary payable in accordance with section 20 hereof
              shall be paid to the  Executive  in  accordance  with  the  normal
              payroll practices of the Company,

all such amounts to be paid to the Executive (or his succession, as the case may
be) net of any  deductions  or amounts to be withheld by the Company as required
by law.

22. In the event of the  termination  of the employment of the Executive for any
reason, all indebtedness still owing by the Executive to the Company at the time
of such  termination  will be forgiven and extinguished and the Company will pay
or  reimburse  to the  Executive  the  amount  of any taxes  incurred  by him in
connection with any such forgiveness.

23. The Executive shall be entitled to participate in all health,  life,  dental
and other insurance plans, if any, as may be maintained by the Company from time
to time for the benefit of its senior executives.

24. The Company shall  reimburse to the Executive all  reasonable  out-of-pocket
expenses  actually and properly incurred by him in the performance of his duties
hereunder  upon  presentation  of expense  statements  or vouchers or such other
supporting information that the Company may reasonably require.

25. The Executive hereby  acknowledges  and agrees that,  during the Term and at
all times  thereafter,  the Executive  will hold in  confidence  all matters and
things  relating to the  business of the Company or any of its  subsidiaries  or
affiliates of which the Executive may acquire  knowledge  during his  employment
with the Company including,  without limitation, all records, papers, documents,
budgets, sketches,  drawings,  specifications,  formulae,  correspondence,  cost
data,  estimates,  market surveys,  suppliers' lists and prices,  manufacturers'
lists and prices, customers' lists and prices, sales, production,  purchasing or
financial  information  of any kind or  description  or any trade secrets or any
proprietary  information of the Company, its subsidiaries and affiliates (all of
the  foregoing  being  herein  collectively  called  the  "Materials");  and the

                                      104
<PAGE>

Executive will not, without the written consent of the Company, except as may be
required in the fulfillment of his duties as an employee of the Company, use any
Materials for any purpose other than the business purposes of the Company and/or
its  subsidiaries  or  affiliates.   Without  limiting  the  generality  of  the
foregoing,  the Executive will not,  without the written consent of the Company,
disclose or  authorize  anyone  else to disclose to any person any  confidential
information or trade secrets  relating to the business of the Company and/or any
of its subsidiaries or affiliates, including, without limitation, any Materials.

26.  The  Executive  hereby  acknowledges  that the  Company  has all  rights to
possession of and title to all Materials and any copies,  extracts and summaries
thereof and other confidential  information originating during the Term or which
may come into his  possession  in any way during  the Term which  relates to the
business  of the  Company  or any of its  subsidiaries  or  affiliates,  and the
Executive further agrees to deliver all of the foregoing promptly to the Company
on the date on which he ceases to be employed hereunder or at any other time the
Company may request,  and not to make or permit to be made,  except for the sole
use or benefit of the Company and its subsidiaries  and affiliates,  any copies,
abstracts or summaries thereof.

27. The Executive hereby  covenants and agrees that,  during the Term, or at any
time until the expiry of two years from the  termination of his employment  with

or its subsidiaries or affiliates.

28. The Executive  agrees that,  except as an employee of the Company,  he shall
not,  during  the Term or at any time  during  the  Non-Competition  Period  (as
hereinafter  defined),  either  individually or as an employee or director of or
consultant to, or in  partnership  or otherwise in connection  with, any person,
firm, association,  syndicate,  company or corporation,  directly or indirectly,
carry on or be engaged in or concerned  with or interested  in, or advise,  lend
money to,  guarantee the debts or obligations of, or permit his name or any part
thereof  to be  used  or  employed  by or  associated  with  any  person,  firm,
association,  syndicate,  company or corporation engaged in or concerned with or
interested in, any business which is the same as or similar to or in competition
in a  material  way with  any of the  businesses  which  are  carried  on by the
Company,  its  subsidiaries  or  affiliates  during  the  Term or at the date of
termination of the  Executive's  employment  with the Company,  the whole in any
Restricted Area (as hereinafter defined);  provided, however, that the foregoing
prohibition  shall not preclude  the passive  investment  by the  Executive in a
maximum of five percent (5%) of the  outstanding  securities of any  corporation
listed on a recognized stock exchange or traded on an over-the-counter market.

       The  Executive  acknowledges  that he has  been  engaged  by the  Company
hereunder for the express  purpose of promoting and  developing  the business of
the Company and that the restrictions set forth in this section 28 are essential
conditions to the execution of this agreement by the Company,  without which the
Company would not have entered into this  agreement.  The Executive  furthermore
acknowledges  that  the  compensation   provided  to  him  hereunder,   and  the
undertakings  of the Company to issue shares to him, have been made partially in
consideration of his undertakings as contained in this section 28. The Executive
expressly  acknowledges  that the  restrictions set forth in this section 28 are
reasonable and valid.

       For the purposes hereof:

              date  hereof and  expiring on the second  anniversary  of the date
              upon which the Executive ceases to be employed by the Company; and

       (b)    "Restricted Area" means Canada and the United States of America.

disregarded as aforesaid if the pledgee establishes to the satisfaction of the
Pass Through Trustee the pledgee's right so to act with respect to such
Certificates and that the pledgee is not one of the Facility Lessees, an Owner
Lessor, an Owner Participant or any Affiliate of any such Person.

          (d)      Any Act by the Holder of any Certificate shall bind the
Holder of every Certificate issued upon the transfer thereof or in exchange
therefor or in lieu thereof, whether or not notation of such Act is made upon
such Certificate.

          (e)      Except as otherwise provided in Section 1.4(c), Certificates
owned by or pledged to any Person shall have an equal and proportionate benefit
under the provisions of this Pass Through Trust Agreement, without preference,
priority or distinction as among all of the Certificates.

          (f)      Notwithstanding anything herein to the contrary, the
Certificates will vote and consent together on all matters as one class and
will not have the right to vote or consent as a separate class on any matter.

                                       11

          (g)      The Pass Through Trustee may fix in advance a record date
for the determination of the Holders entitled to give any request, demand,
authorization, direction, notice, consent, waiver or other Act solicited by a
Facility Lessee, but the Pass Through Trustee shall not have any obligation to
do so.

     Section 1.5   Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with a provision of the Trust Indenture Act that
is required or deemed under such Act to be a part of and govern this Pass
Through Trust Agreement, such required or deemed provision shall, so long as
the Certificates shall be subject to the Trust Indenture Act, control. If any
provision of this Pass Through Trust Agreement modifies or excludes any
provision of the Trust Indenture Act that may be so modified or excluded, the
latter provision shall be deemed to apply to this Indenture as so modified or
to be excluded, as the case may be.

SECTION 2.    ACQUISITION OF LESSOR NOTES; ORIGINAL ISSUANCE OF CERTIFICATES

  Section 2.1 Issuance of Certificates; Acquisition of Lessor Notes.

          (a)      Pass Through Trustee, at or promptly following the execution
and delivery of this Pass Through Trust Agreement, shall also execute and
deliver Participation Agreements, in the form delivered to the Pass Through
Trustee on or prior to the date of the execution and delivery hereof. Upon
delivery of an authentication order by each of the Facility Lessees and the
satisfaction of the closing conditions with respect to the Lessor Notes in
Section 4 of the Participation Agreement, the Pass Through Trustee shall
execute, deliver and authenticate, on behalf of the Pass Through Trust,
Certificates equaling in the aggregate the total principal amount of the Lessor
Notes deposited into the Pass Through Trust on the Issuance Date. The
Certificates so executed, delivered and authenticated on the Transfer Date
shall evidence the entire ownership of the Pass Through Trust. The Pass Through
Trust shall issue such Certificates on the Issuance Date, in authorized
denominations and in such Fractional Undivided Interests, so as to result in
the receipt of consideration (the "Consideration") in an amount equal to the
aggregate principal amount of such Lessor Notes referred to in the second
preceding sentence. The Pass Through Trust shall purchase Lessor Notes on the
Transfer Date at an aggregate purchase price equal to the amount of the
Consideration so received. Except as provided in Sections 3.4 and 3.5 hereof,
the Pass Through Trustee shall not execute or deliver Certificates in excess of
the aggregate amount specified in this paragraph. The aggregate Fractional
Undivided Interest of Certificates shall not at any time exceed $454,500,000

          (b)      If, on or prior to the Issuance Date, the Facility Lessees
shall deliver to the Pass Through Trustee a Postponement Notice relating to all
of the Lessor Notes related to any Facility, the Pass Through Trustee shall
postpone the purchase of all of the Lessor Notes related to such Facility and
shall deposit into an escrow account (the "Escrow Account") to be maintained as
part of the Pass Through Trust an amount equal to the purchase price of such
Lessor Notes (the "Escrowed Funds"). The Escrowed Funds so deposited shall be
invested by the Pass Through Trustee at the written direction and risk of, and
for the benefit of, the Facility Lessees in Specified Investments (i) maturing
no later than the scheduled Transfer Date or (ii) if no such Transfer Date has
been scheduled, maturing on the next Business Day, or (iii) if the Facility
Lessees have given notice to the Pass Through Trustee that the Lessor Notes
will not be

                                       12

<PAGE>

issued, maturing on the next Special Distribution Date but in no event later
than December 1, 2001, if such investments are reasonably available for
purchase. The Pass Through Trustee shall make a withdrawal from the Escrow
Account only as provided in this Pass Through Trust Agreement. Upon request of
the Facility Lessees on the satisfaction or waiver of the closing conditions
specified in the Participation Agreements on or prior to the Cut-off Date, the
Pass Through Trustee shall purchase all of the Lessor Notes related to any
Facility with the Escrowed Funds withdrawn from the Escrow Account. The
purchase price shall equal the principal amount of such Lessor Notes.

          The Pass Through Trustee shall hold all Specified Investments until
the maturity thereof and will not sell or otherwise transfer Specified
Investments. If Specified Investments held in the Escrow Account mature prior
to the Transfer Date, any proceeds received on the maturity of such Specified
Investments shall be reinvested by the Pass Through Trustee at the written
direction and risk of, and for the benefit of, the Facility Lessees in
Specified Investments maturing as provided in the preceding paragraph.

          Any earnings on Specified Investments received from time to time by
the Pass Through Trustee shall be promptly deposited and held in the Escrow
Account by the Pass Through Trustee. The Facility Lessees shall pay to the Pass
Through Trustee for deposit to the Escrow Account an amount equal to any losses
on such Specified Investments as incurred. On the initial regular Distribution
Date, the Facility Lessees will pay (in immediately available funds) to the
Pass Through Trustee an amount equal to the negative difference between the
amount of earnings received by the Pass Through Trustee on the Specified
Investments in the Escrow Account and the amount of interest that would have
accrued on the Lessor Notes, if any, purchased after the Issuance Date if the
Lessor Notes had been purchased on the Issuance Date to, from the Issuance Date
to, but not including, the date of the purchase of the Lessor Notes by the Pass
Through Trustee.

          If the Facility Lessees notify the Pass Through Trustee prior to
the Cut-off Date that the Lessor Notes or any portion thereof will not be
issued on or prior to the Cut-off Date for any reason (it being understood that
if any Lessor Notes related to one Facility are issued, then all Lessor Notes
related to such Facility shall be issued), on the next Special Distribution
Date occurring not less than 20 days following the date of such notice, (i) the
Facility Lessees shall pay to the Pass Through Trustee for deposit in the
Special Payments Account, in immediately available funds, an amount equal to
the sum of (x) the negative difference between the amount of earnings received
by the Pass Through Trustee on Specified Investments in the Escrow Account and
the amount of interest that would have accrued on the Lessor Notes at a rate
equal to the interest rate applicable to the Certificates from the Issuance
Date to, but not including, such Special Distribution Date and (y) the
Make-Whole Amount and (ii) the Pass Through Trustee shall transfer an amount
equal to that amount of Escrowed Funds that would have been used to purchase
the Lessor Notes designated in such notice and the amount paid by the Facility
Lessees pursuant to the immediately preceding clause (i) to the Special
Payments Account for distribution as a Special Payment in accordance with the
provisions hereof. Any earnings received by the Pass Through Trustee on
Specified Investments in the Escrow Account in excess of the amounts payable
pursuant to the preceding sentence shall be refunded to the Facility Lessee
following the payment of all amounts due hereunder.

                                       13

<PAGE>

          (c)      The Facility Lessees' Assumption of Lessor Notes. If a
Facility Lessee shall assume the obligations of the applicable Owner Lessor
under its Lessor Note pursuant to the Collateral Trust Indenture, the Pass
Through Trustee shall, upon its receipt of written instructions from such
Facility Lessee, surrender the applicable Lessor Notes issued pursuant to the
Collateral Trust Indenture to the Indenture Trustee in exchange for new Lessor
Notes of the same aggregate outstanding principal amount as the Lessor Notes so
surrendered, bearing interest at the same rate, and having the same maturity
and amortization schedule, and otherwise of similar tenor, issued under the
Collateral Trust Indenture and any new Collateral Trust Indenture entered into
by such Facility Lessee and the Indenture Trustee in connection with such
assumption, and thereafter each reference to such Lessor Notes in this Pass
Through Trust Agreement shall be deemed to mean a reference to such new Lessor
Notes or the existing Lessor Notes as assumed by such Facility Lessee.

          (d)      Authentication. Any authentication order delivered by any of
the Facility Lessees hereunder shall be signed by one of such Facility Lessee's
authorized signatories and shall specify the amount and maturity of the
Certificates to be authenticated and the date on which the original issue of
Certificates is to be authenticated. The Pass Through Trustee may appoint an
authenticating agent to authenticate the Certificates. Unless limited by the
terms of such appointment, an authenticating agent may authenticate the
Certificates whenever the Pass Through Trustee may do so. Each reference in
this Pass Through Trust Agreement to authentication by the Pass Through Trustee
includes authentication by such agent. An authenticating agent has the same
rights as any Registrar, Paying Agent or agent for service of notices and
demands.

      Section 2.2  Acceptance by Pass Through Trustee. The Pass Through
Trustee, upon the execution and delivery of this Pass Through Trust Agreement,
acknowledges on behalf of the Pass Through Trust its acceptance of all right,
title, and interest in and to the Lessor Notes acquired pursuant to Section 2.1
hereof and declares that the Pass Through Trustee holds and will hold such
right, title, and interest, together with all other property constituting the
Trust Property, for the benefit of all present and future Certificateholders,
upon the trusts herein set forth. By its payment for and acceptance of each
Certificate issued to it hereunder, each initial Certificateholder as grantor
of the Pass Through Trust thereby joins in the creation and declaration of the
Pass Through Trust. The Pass Through Trustee shall be under no duty or
obligation to inspect, review or examine the Lessor Notes to determine that
they are genuine, valid, binding, enforceable or appropriate for the
represented purpose or that they are other than what they purport to be on
their face.

     Section 2.3   Limitation of Powers. The Pass Through Trust is constituted
solely for the purpose of making the investment in the Lessor Notes, and,
except as set forth herein, the Pass Through Trustee is not authorized or
empowered to acquire any other investments or engage in any other activities
and, in particular, the Pass Through Trustee is not authorized or empowered to
do anything that would cause the Pass Through Trust to fail to qualify as a
pass through entity for federal income tax purposes (including, as subject to
this restriction, acquiring any Undivided Interest or any portion thereof by
bidding the Lessor Notes or otherwise, or taking any action with respect to any
Undivided Interest or any portion thereof once acquired).

SECTION 3.    THE CERTIFICATES

     Section 3.1   Form, Denomination and Execution of Certificates. The
Certificates shall be known as the "8.400% Pass Through Certificates, Series A"
of the Pass Through Trust and shall each represent a Fractional Undivided
Interest. The Certificates shall be issued in registered form without coupons
and shall be substantially in the form attached hereto as Exhibit A, with such
omissions, variations and insertions as are permitted by this Pass Through
Trust Agreement, and may have such letters, numbers or other marks of
identification and such legends or endorsements printed, lithographed or
engraved thereon, as may be required to comply with the rules of any securities
exchange on which such Certificates may be listed or to conform to any usage in
respect thereof, or as may, consistently herewith, be prescribed by the Pass
Through Trustee or by the officer executing such Certificates, such
determination by said officer to be evidenced by such officer signing the
Certificates. Except as provided in Section 3.9, definitive Certificates
shall be printed, lithographed or engraved or produced by any combination of
these methods, all as determined by the officer executing such Certificates, as
evidenced by such officer's execution of such Certificates.

          (c)      During the period beginning on the Issuance Date and ending
on the expiration of the applicable holding period in Rule 144(k) of the
Securities Act, all Certificates issued on the Issuance Date, and all
Certificates issued upon registration of transfer of, or in exchange for, such
Certificates, shall be "Restricted Certificates" and shall be subject to the
restrictions on transfer provided in the legend set forth on the face of the
form of certificate in Exhibit A; provided, however, that the term "Restricted
Certificates" shall not include Certificates as to which such restrictions on
transfer have been terminated in accordance with Section 3.4. All Restricted
Certificates shall bear the legend set forth on the face of the Certificate in
Exhibit A. Certificates which are not Restricted Certificates shall not bear
such legend.

          (d)      The Certificates shall be issued in minimum denominations of
$100,000 or integral multiples of $1,000 in excess thereof.

          (e)      The Certificates shall be executed on behalf of the Pass
Through Trust by manual or facsimile signature of a Responsible Officer of the
Pass Through Trustee. Certificates bearing the manual or facsimile signature of
an individual who was, at the time when such signature was affixed, authorized
to sign on behalf of the Pass Through Trustee shall be valid and binding
obligations of the Pass Through Trust, notwithstanding that such individual has
ceased to be so authorized prior to the authentication and delivery of such
Certificates or did not hold such office at the date of such Certificates. No
Certificate shall be entitled to any benefit under this Pass Through Trust
Agreement, or be valid for any purpose unless there appears on such Certificate
a certificate of authentication substantially in the form set forth in Exhibit
B hereto executed by the Pass Through Trustee by manual signature, and such
certificate of authentication upon any Certificate shall be conclusive
evidence, and the only evidence, that such Certificate has been duly
authenticated and delivered hereunder. All Certificates shall be dated the date
of their authentication.

  Section 3.2      Authentication of Certificates. Upon delivery of an
authentication order by the Facility Lessees, the Pass Through Trustee shall
cause to be delivered Certificates duly

                                       15

<PAGE>

authenticated by the Pass Through Trustee, in authorized denominations equaling
in the aggregate the aggregate principal amount set forth in the authentication
order evidencing the entire ownership of the Pass Through Trust.

     Section 3.3   Temporary Certificates. Pending the preparation of definitive
Certificates, the Pass Through Trustee may execute, authenticate and deliver
temporary Certificates which are printed, lithographed, typewritten, or
otherwise produced, in any denomination, containing substantially the same
terms and provisions as set forth in Exhibit A, except for such appropriate
insertions, omissions, substitutions and other variations relating to their
temporary nature as the officer executing such temporary Certificates may
determine, as evidenced by his or her execution of such temporary Certificates.

          If temporary Certificates are issued, the Facility Lessees will
cause definitive Certificates to be prepared without unreasonable delay. After
the preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the Corporate Trust Office of the Pass Through Trustee, or at
the office or agency of the Pass Through Trustee maintained in accordance with
Section 7.12, without charge to the Holder. Upon surrender for cancellation of
any one or more temporary Certificates, the Pass Through Trustee shall execute,
authenticate and deliver in exchange therefor definitive Certificates of
authorized denominations of a like aggregate Fractional Undivided Interest.
Until so exchanged, such temporary Certificates shall in all respects be
entitled to the same benefits under this Pass Through Trust Agreement as
definitive Certificates.

  Section 3.4 Registration of Transfer and Exchange of Certificates.

          (a)      The Pass Through Trustee shall cause to be kept, at the
office or agency to be maintained by it in accordance with the provisions of
Section 7.12, a register (the "Register") in which, subject to the provisions
of this Section 3.4, Section 3.9 and the Certificates, the Pass Through Trustee
shall provide for the registration of Certificates and of transfers and
exchanges of Certificates as herein provided. The Pass Through Trustee shall
initially be the registrar (the "Registrar") for the purpose of registering
Certificates and transfers and exchanges of Certificates as herein provided.
The Facility Lessees may, upon notice to the Pass Through Trustee, change the
Registrar at any time.

          (b)      Every Restricted Certificate shall be subject to the
restrictions on transfer provided in the legend required to be set forth on the
face of each Restricted Certificate pursuant to Section 3.1, and the Holder of
each Restricted Certificate, by such Holder's acceptance thereof, agrees to be
bound by such restrictions on transfer. Whenever any Restricted Certificate is
presented or surrendered for registration of transfer or for exchange for a
Certificate registered in a name other than that of the Holder, such Restricted
Certificate must be accompanied by a certificate in substantially the form set
forth in Exhibit C hereto, dated the date of such surrender and signed by the
Holder of such Restricted Certificate, or such Holder's attorney duly
authorized in writing, as to compliance with such restrictions on transfer.
Neither the Pass Through Trustee nor any Registrar shall be required to accept
for such registration of transfer or exchange any Restricted Certificate not so
accompanied by a properly completed certificate. Notwithstanding the preceding
two sentences, a properly completed certificate shall not be

                                       16

<PAGE>

required in connection with any transfer of any Restricted Certificate through
the facilities of DTC or any other United States securities clearance and
settlement organization; provided, that such transfer does not require a change
in the name (other than to another nominee of DTC or such other securities
clearance and settlement organization) in which such Restricted Certificate is
then registered.

          Whenever any Restricted Certificate is proposed to be transferred
by a Holder to an Institutional Accredited Investor, the Pass Through Trustee
shall have received from such Institutional Accredited Investor, prior to such
transfer, a signed letter substantially in the form of Exhibit D relating to
certain representations and agreements regarding restrictions on transfer of
such Restricted Certificate. In addition, the Holder of the Restricted
Certificate proposed to be transferred must, prior to such transfer, furnish to
the Registrar such certifications (as required by, and in the form set forth
in, this Pass Through Trust Agreement, opinions of counsel or other information
as the Registrar may reasonably request to confirm that such transfer is being
made pursuant to an exemption from, or in a transaction not subject to, the
registration requirements of the Securities Act.

          The restrictions imposed by this Section 3.4 and Section 3.1 upon
the transferability of any particular Restricted Certificate shall cease and
terminate if and when such Restricted Certificate has been (i) sold pursuant to
an effective registration statement under the Securities Act, or (ii)
transferred pursuant to Rule 144 under the Securities Act (or any successor
provision thereto), unless the Holder thereof is an affiliate of any Facility
Lessee within the meaning of Rule 144 (or such successor provision). Any
Restricted Certificate as to which such restrictions on transfer shall have
expired in accordance with their terms or shall have terminated may, upon
surrender of such Restricted Certificate for exchange to the Pass Through
Trustee or any Registrar in accordance with the provisions of this Section 3.4
(accompanied, in the event that such restrictions on transfer have terminated
by reason of a transfer pursuant to Rule 144 or any successor provision, by an
Opinion of Counsel having substantial experience in practice under the
Securities Act and otherwise reasonably acceptable to each of the Facility
Lessees, addressed to each of the Facility Lessees and the Pass Through Trustee
and in form acceptable to each of the Facility Lessees, to the effect that the
transfer of such Restricted Certificate has been made in compliance with Rule
144 or such successor provision), be exchanged for a new Certificate, of
authorized denominations of a like aggregate Fractional Undivided Interest,
which shall not bear the restrictive legend required by Section 3.1. The Pass
Through Trustee shall not be liable for any action taken or omitted to be taken
by it in good faith in accordance with the aforementioned Opinion of Counsel.

          (c)      Upon surrender for registration of transfer of any
Certificate that is not a Restricted Certificate at the Corporate Trust Office,
or such other office or agency, the Pass Through Trustee shall execute,
authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates, in authorized denominations of a
like aggregate Fractional Undivided Interest if its requirements for such
transaction are met.

          (d)      At the option of a Certificateholder, Certificates may be
exchanged for other Certificates, in authorized denominations and of a like
aggregate Fractional Undivided Interest, upon surrender of the Certificates to
be exchanged at any such office or agency; provided, that a Restricted
Certificate may only be exchanged for another Restricted Certificate,

                                       17

<PAGE>

until such restrictions on such Restricted Certificate shall cease and
terminate in accordance with the terms of this Section 3.4. Whenever any
Certificates are so surrendered for exchange, the Pass Through Trustee shall
execute, authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive. Every Certificate presented or
surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form satisfactory to each of
the Facility Lessees and the Pass Through Trustee and the Registrar duly
executed by the Certificateholder thereof or its attorney duly authorized in
writing.

          (e)      No service charge shall be made to a Certificateholder for
any registration of transfer or exchange of Certificates, but the Pass Through
Trustee shall require payment of a sum sufficient to cover any tax or charge
that may be imposed in connection with any transfer or exchange of Certificates.

          (f)      All Certificates surrendered for registration of transfer
and exchange shall be canceled and disposed of in accordance with the usual
practices of the Pass Through Trustee.

  Section 3.5 Mutilated, Destroyed, Lost or Stolen Certificates. If any
mutilated Certificate is surrendered to the Registrar, or the Registrar receives
evidence to its satisfaction of the destruction, loss or theft of any
Certificate and in the case of such destruction, loss or theft, there is
delivered to the Registrar, the Pass Through Trustee, the Facility Lessees and
the applicable Owner Lessor such security, indemnity or bond as may be required
by them to protect each of them and the Pass Through Trust from any loss that
any of them may suffer if a Certificate is replaced, then, in the absence of
notice to the Registrar or the Pass Through Trustee that such Certificate has
been acquired by a bona fide purchaser, the Pass Through Trustee, on behalf of
the Pass Through Trust, shall execute, authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Certificate, a new
Certificate of like Fractional Undivided Interest with the same final
Distribution Date. In connection with the issuance of any new Certificate under
this Section 3.5, the Pass Through Trustee shall require the payment of a sum
sufficient to cover any tax or other charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Pass
Through Trustee and the Registrar) connected therewith. Any duplicate
Certificate issued pursuant to this Section 3.5 shall constitute conclusive
evidence of the appropriate Fractional Undivided Interest in the Pass Through
Trust, as if originally issued, whether or not the lost, stolen or destroyed
Certificate shall be found at any time.

  Section 3.6 Persons Deemed Owners. Prior to due presentation of a Certificate
for registration of transfer, the Pass Through Trustee, the Facility Lessees,
the applicable Owner Lessor, the Registrar and any Paying Agent may treat the
person in whose name any Certificate is registered as the owner of such
Certificate for the purpose of receiving distributions pursuant to Section 4.2
and for all other purposes whatsoever, and neither the Pass Through Trustee, any
Facility Lessee, the applicable Owner Lessor, the Registrar nor any Paying Agent
shall be affected by any notice to the contrary.

  Section 3.7 Cancellation. All Certificates surrendered for payment, transfer
or exchange shall, if surrendered to any Person a party hereto other than the
Registrar, be delivered by such Person to the Registrar for cancellation. No
Certificates shall be authenticated in lieu of

                                       18

<PAGE>

or in exchange for any Certificates canceled as provided in this Section 3.7,
except as expressly permitted by this Pass Through Trust Agreement. All
canceled Certificates held by the Registrar shall be disposed of in accordance
with the usual practice of the Pass Through Trustee and, if destroyed, a
certification of their destruction shall be delivered to the Pass Through
Trustee.

  Section 3.8 Limitation of Liability for Payments. All payments or
distributions made to Certificateholders under this Pass Through Trust Agreement
shall be made only from the Trust Property and only to the extent that the Pass
Through Trustee shall have received sufficient income or proceeds from the Trust
Property to make such payments in accordance with the terms of Section 4 of this
Pass Through Trust Agreement. Each Holder of a Certificate, by its acceptance of
such Certificate, agrees that it will look solely to the income and proceeds
from the Trust Property to the extent available for distribution to the Holder
thereof as provided in this Pass Through Trust Agreement. Nothing in this Pass
Through Trust Agreement shall be construed as an agreement, or otherwise
creating an obligation, of (a) any Facility Lessee, the Pass Through Trust or
the Pass Through Trustee to pay any of the principal, premium, if any, or
interest due from time to time under the Lessor Notes, or (b) any Facility
Lessee, the Pass Through Trust or the Pass Through Trustee to pay any amount due
from time to time in respect of the Certificates. The liability of an Owner
Lessor under the applicable Lessor Notes shall be limited as set forth therein
and in the applicable Collateral Trust Indenture.

  Section 3.9 Book-Entry and Definitive Certificates.

          (a)      Except for Certificates issued to Institutional Accredited
Investors which must be issued in the form of definitive, fully registered
Certificates ("Definitive Certificates"), the Certificates may be issued in the
form of one or more typewritten Certificates representing the Book-Entry
Certificates to be delivered to DTC, the initial Clearing Agency, by, or on
behalf of, the Pass Through Trustee. In such case, the Certificates delivered
to DTC shall initially be registered on the Register in the name of Cede & Co.,
the nominee of the initial Clearing Agency, and no Certificate Owner will
receive a definitive certificate representing such Certificate Owner's interest
in the Certificates, except as provided above and in subsection (d) below. As
to the Book-Entry Certificates, unless and until Definitive Certificates have
been issued pursuant to subsection (d) below:

                   (i)      the provisions of this Section 3.9 shall be in full
          force and effect;

                   (ii)     the Facility Lessees, any Owner Lessor, the Paying
          Agent, the Registrar and the Pass Through Trustee may deal with the
          Clearing Agency for all purposes (including the making of
          distributions on the Certificates) as the authorized representative
          of the Certificate Owners;

                   (iii)    to the extent that the provisions of this Section
          3.9 conflict with any other provisions of this Pass Through Trust
          Agreement (other than the provisions of any supplemental agreement
          amending this Section 3.9 as permitted by this Pass Through Trust
          Agreement), the provisions of this Section 3.9 shall control;

                                       19

<PAGE>

                   (iv)      the rights of Certificate Owners shall be
          exercised only through the Clearing Agency and shall be limited to
          those established by law and agreements between such Certificate
          Owners and the Clearing Agency Participants; and until Definitive
          Certificates are issued pursuant to subsection (d) below, the
          Clearing Agency will make book-entry transfers among the Clearing
          Agency Participants and receive and transmit distributions of
          principal and interest and premium, if any, on the Certificates to
          such Clearing Agency Participants; and

                   (v)      whenever this Pass Through Trust Agreement requires
          or permits actions to be taken based upon instructions or directions
          of Certificateholders holding Certificates evidencing a specified
          percentage of the Fractional Undivided Interests in the Pass Through
          Trust, the Clearing Agency shall be deemed to represent such
          percentage only to the extent that it has received instructions to
          such effect from Certificate Owners and/or Clearing Agency
          Participants owning or representing, respectively, such required
          percentage of the beneficial interest in Certificates and has
          delivered such instructions to the Pass Through Trustee.  The Pass
          Through Trustee shall have no obligation to determine (and shall
          incur no liability in connection with any determination of) whether
          the Clearing Agency has in fact received any such instructions.

          (b)      With respect to Book-Entry Certificates, whenever notice or
other communication to the Certificateholders is required under this Pass
Through Trust Agreement, unless and until Definitive Certificates shall have
been issued pursuant to subsection (d) below, the Pass Through Trustee shall
give all such notices and communications specified herein to be given to
Certificateholders to the Clearing Agency and/or the Clearing Agency
Participants (and, upon receipt of a valid Certificate Owner Request, to the
Certificateholder or Certificate Owner making such request), and shall make
available additional copies as reasonably requested by such Clearing Agency
Participants.

          (c)      Unless and until Definitive Certificates are issued pursuant
to subsection (d) below, on the Record Date prior to each applicable
Distribution Date and S pecial Distribution Date, the Pass Through Trustee will
request from the Clearing Agency a "Securities Position Listing" setting forth
the names of all Clearing Agency Participants reflected on the Clearing
Agency's books as holding interests in the Certificates on such Record Date.
The Pass Through Trustee shall mail to each such Clearing Agency Participant
the statements described in Section 4.3 hereof.

          (d)      If with respect to the Certificates (i) any Facility Lessee
advises the Pass Through Trustee in writing that the Clearing Agency is no
longer willing or able to properly discharge its responsibilities and the
Facility Lessees are unable to locate a qualified successor within 90 days,
(ii) the Facility Lessees (or, following the occurrence of a Lease Event of
Default, the applicable Owner Lessors) at their option, advise the Pass Through
Trustee in writing that they elect to terminate the book-entry system through
the Clearing Agency or (iii) after the occurrence of an Event of Default,
Certificate Owners of Book-Entry Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest in the Pass Through
Trust, by Act of said Certificate Owners delivered to the Facility Lessees and
the

                                       20

Pass Through Trustee, advise the Facility Lessees, the Owner Lessors, the Pass
Through Trustee and the Clearing Agency through the Clearing Agency
Participants in writing that the continuation of a book-entry system through
the Clearing Agency is no longer in the best interests of the Certificate
Owners, then the Pass Through Trustee shall notify all Certificate Owners,
through the Clearing Agency, of the occurrence of any such event and of the
availability of Definitive Certificates. Upon surrender to the Pass Through
Trustee of all the Certificates held by the Clearing Agency, accompanied by
registration instructions from the Clearing Agency for registration of
Definitive Certificates in the names of Certificate Owners, the Pass Through
Trust shall issue and deliver the Definitive Certificates in accordance with
the instructions of the Clearing Agency. None of the Facility Lessees, the
Owner Lessors, the Registrar, the Paying Agent or the Pass Through Trustee
shall be liable for any delay in delivery of such instructions and may
conclusively rely on, and shall be protected in relying on, such registration
instructions. Upon the issuance of Definitive Certificates, the Pass Through
Trustee shall recognize the Person in whose name the Definitive Certificates
are registered in the Register as Certificateholder hereunder. None of the
Facility Lessees nor the Pass Through Trustee shall be liable if the Facility
Lessees are unable to locate a qualified successor Clearing Agency.

          (e)      The Certificates sold in offshore transactions in reliance
on Regulation S under the Securities Act will be represented initially by one
or more temporary Book-Entry Certificates, in definitive, fully registered form
without interest coupons (collectively, the "Temporary Regulation S Global
Certificate") and will be deposited with the Pass Through Trustee as custodian
for DTC and registered in the name of a nominee of DTC for the accounts of the
Euroclear System ("Euroclear") and Clearstream Banking, S.A. ("Clearstream").
Each Temporary Regulation S Global Certificate will be exchangeable for one or
more permanent Book-Entry Certificate (collectively, the "Permanent Regulation
S Global Certificate," and together with the Temporary Regulation S Global
Certificate, the "Regulation S Global Certificate") on or after 40 days after
the later of the commencement of the offering of the Certificates and the
Issuance Date upon certification that the beneficial interests in such
Book-Entry Certificate are owned by persons who are not U.S. persons as defined
in Regulation S. Prior to the expiration of such 40-day period, beneficial
interests in the Temporary Regulation S Global Certificate may be held only
through Euroclear or Clearstream, and any resale or other transfer of such
interests to U.S. persons shall not be permitted during such period unless such
resale or transfer is made pursuant to Rule 144A or Regulation S under the
Securities Act and in accordance with the certification requirements specified
in Section 3.9(f) below. The aggregate original principal amount of the
Regulation S Global Certificate may from time to time be increased or decreased
by adjustments made on the records of the Pass Through Trustee, as custodian
for DTC, in connection with a corresponding decrease or increase in the
aggregate original principal amount of a Definitive Certificate or the
Restricted Global Certificate, as hereinafter provided.

          (f)      The Certificates sold in reliance on Rule 144A under the
Securities Act will be represented by a one or more permanent Book-Entry
Certificate, in definitive, fully registered form without interest coupons
(collectively, the "Restricted Global Certificate"), which will be deposited
with the Pass Through Trustee as custodian for DTC and registered in the name
of a nominee of DTC. Prior to the 40th day after the later of the commencement
of the offering of the Certificates and the Issuance Date, a beneficial
interest in the Temporary Regulation S Global Certificate may be transferred to
a person who takes delivery in the form of

                                       21

<PAGE>

an interest in the Restricted Global Certificate only upon receipt by the Pass
Through Trustee of a written certification from the transferor (in the form of
Exhibit C hereto) to the effect that such transfer is being made to a person
who the transferor reasonably believes is a "qualified institutional buyer"
within the meaning of Rule 144A in a transaction meeting the requirements of
Rule 144A and in accordance with any applicable securities laws of any state of
the United States or any other jurisdiction. Beneficial interests in the
Restricted Global Certificate may be transferred to a person who takes delivery
in the form of an interest in the Regulation S Global Certificate whether
before, on or after such 40th day, only upon receipt by the Pass Through
Trustee of a written certification (in the form of Exhibit C hereto) to the
effect that such transfer is being made in accordance with Regulation S under
the Securities Act and, if such transfer occurs prior to such 40th day, the
interest will be held immediately thereafter only through Euroclear or
Clearstream. The aggregate initial principal amount of the Restricted Global
Certificate may from time to time be increased or decreased by adjustments made
on the records of the Pass Through Trustee, as custodian for DTC, in connection
with a corresponding decrease or increase in the aggregate initial principal
amount of a Definitive Certificate or a Regulation S Global Certificate, as
hereinafter provided.

          (g)      Any beneficial interest in one of the Book-Entry
Certificates that is transferred to a person who takes delivery in the form of
an interest in another Book-Entry Certificate will, upon transfer, cease to be
an interest in such first Book-Entry Certificate and become an interest in such
other Book-Entry Certificate and, accordingly, will thereafter be subject to
all transfer restrictions, if any, and other procedures applicable to
beneficial interests in such other Book-Entry Certificate for so long as it
remains such an interest. Upon the transfer of Definitive Certificates to a
qualified institutional buyer or in accordance with Regulation S, such
Definitive Certificates will be exchanged for an interest in a Book-Entry
Certificate.

          (h)      The Facility Lessees and the Pass Through Trustee, if
necessary, shall each enter into the Letter of Representations with respect to
the Certificates and fulfill its responsibilities thereunder.

     Section 3.10  Form of Certification. In connection with any certification
contemplated by Section 3.4, relating to compliance with certain restrictions
relating to transfers of Restricted Certificates, such certification shall be
provided substantially in the form of Exhibit C hereto, with only such changes
as shall be reasonably approved by the Facility Lessees and reasonably
acceptable to the Pass Through Trustee.

          (a)      The Pass Through Trust shall establish and maintain on
behalf of the Certificateholders the Certificate Account with the Pass Through
Trustee as one or more non-interest bearing accounts. The Pass Through Trustee
shall hold the Certificate Account in trust for the benefit of the
Certificateholders, and shall make or permit withdrawals therefrom only as
provided in this Pass Through Trust Agreement. On each day when a Scheduled
Payment is made under a Lease to the Pass Through Trustee, as holder of the
Lessor Notes issued under the related Collateral Trust Indenture, the Pass
Through Trustee upon receipt of

                                       22

<PAGE>

Scheduled Payment in the Certificate Account.

          (b)      The Pass Through Trust shall establish and maintain on
behalf of the Certificateholders the Special Payments Account with the Pass
Through Trustee as one or more accounts, which shall be non-interest bearing
except as provided in Section 4.4. The Pass Through Trustee shall hold the
Special Payments Account in trust for the benefit of the Certificateholders,
and shall make or permit withdrawals therefrom only as provided in this Pass
Through Trust Agreement. On each day when a Special Payment is made to the Pass

          (c)      The Pass Through Trustee shall present to the applicable
Indenture Trustee each Lessor Note on the date of its stated final maturity, or

  Section 4.2 Distributions from Certificate Account and Special Payments
              Account.

          (a)      On each Distribution Date if the Pass Through Trustee
receives payment of the Scheduled Payments due on any Lessor Notes on such date
by 12:00 noon, New York time, on such date, the Pass Through Trustee shall
distribute out of the Certificate Account the entire amount deposited therein
pursuant to Section 4.1(a). If a Scheduled Payment is received by the Pass
Through Trustee after 12:00 noon, New York time, on a Distribution Date, such
payment shall be distributed on the next Business Day. If a Scheduled Payment
is not received by the Pass Through Trustee on a Distribution Date but is
received prior to the time such payment would become a Special Payment, such
payment shall be distributed (i) on the date received, if received by 12:00
noon, New York time, on such date or (ii) on the next Business Day, if received
after 12:00 noon, New York time, on such date. There shall be so distributed to
each Certificateholder of record on the Record Date with respect to such
Distribution Date (other than as provided in Section 11.1 concerning the final
distribution) (i) if (A) DTC is the Certificateholder of record, or (B) a
Certificateholder holds a Certificate or Certificates in an aggregate amount
greater than $10,000,000 or (C) a Certificateholder holds a Certificate or
Certificates in an aggregate amount greater than $1,000,000 and so requests to
the Pass Through Trustee, by wire transfer in immediately available funds to an
account maintained by such Certificateholder with a bank, or (ii) if none of
the above apply, by check mailed to such Certificateholder at the address
appearing in the Register, such Certificateholder's pro rata share (based on
the aggregate Fractional Undivided Interest held by such Certificateholder) of
the aggregate amount in the Certificate Account.

          (b)      On each Special Distribution Date with respect to any Special
Payment, if the Pass Through Trustee receives the Special Payments due on the
required date by 12:00 noon, New York time, on such date, the Pass Through
Trustee shall distribute out of the Special Payments Account the entire amount
deposited therein with respect to such Special Payment pursuant to this Section
4.2(b). The Pass Through Trustee shall make such distribution on a pro rata
basis among the Certificateholders. If a Special Payment is received by the
Pass Through

                                       23

<PAGE>

Trustee after 12:00 noon, New York time, on a Special Distribution Date, such
payment shall be distributed on the next Business Day. If a Special Payment is
not received by the Pass Through Trustee on a Special Distribution Date, such
payment shall be distributed (i) on the date received, if received by 12:00
noon, New York time, on such date or (ii) on the next Business Day, if received
after 12:00 noon, New York time, on such date. There shall be so distributed to
each Certificateholder of record on the Record Date with respect to such
Special Distribution Date (other than as provided in Section 11.1 concerning
the final distribution) (i) if (A) DTC is the Certificateholder of record, or
(B) a Certificateholder holds a Certificate or Certificates in an aggregate
amount greater than $10,000,000 or (C) a Certificateholder holds a Certificate
or Certificates in an aggregate amount greater than $1,000,000 and so requests
to the Pass Through Trustee, by wire transfer in immediately available funds to
an account maintained by the Certificateholder with a bank, or (ii) if none of
the above apply, by check mailed to such Certificateholder at the address
appearing in the Register, such Certificateholder's pro rata share (based on
the aggregate Fractional Undivided Interest held by such Certificateholder) of
the aggregate amount in the Special Payments Account on account of such Special
Payment.

          (c)      The Pass Through Trustee shall, at the expense of the
Facility Lessees, cause notice of each Special Payment to be mailed to (i) each
Certificateholder, at the address of such Certificateholder as it appears in
the Register and (ii) any Certificate Owner who has made a valid Certificate
Owner Request, at the address specified in such Certificate Owner Request. In
the event of prepayment of any Lessor Notes, such notice shall be mailed not
less than 20 days prior to the date any such Special Payment is scheduled to be
distributed. In the case of any other Special Payments, such notice shall be
mailed as soon as practicable after the Pass Through Trustee has confirmed that
it has received funds for such Special Payment. Notices mailed by the Pass
Through Trustee shall set forth:

                   (i)      the Special Distribution Date and the Record Date
          therefor (except as otherwise provided in Section 11.1);

                   (ii)     the amount of the Special Payment per $1,000 of face
          amount of Certificates and the amount thereof constituting principal,
          premium, if any, and interest;

                   (iii)    the reason for the Special Payment; and

                   (iv)     if the Special Distribution Date is the same date
          as a Distribution Date, the total amount to be received on such date
          per $1,000 of face amount of Certificates.

If the amount of premium payable upon the prepayment of a Lessor Note has not
been calculated at the time that the Pass Through Trustee mails notice of a
Special Payment, it shall be sufficient if the notice sets forth the other
amounts to be distributed and states that any premium received will also be
distributed. If a Distribution Date or Special Distribution Date is not a
Business Day, distribution shall be made on the immediately following Business
Day.

  Section 4.3 Statements to Certificateholders.

forth the following information (per a $1,000 face amount Certificate):

                   (i)      the amount of such distribution allocable to
          principal and the amount allocable to premium, if any; and

                   (ii)      the amount of such distribution allocable to
          interest.

          (b)      Within a reasonable period of time after the end of each
calendar year but not later than the latest date permitted by law, the Pass
Through Trustee shall furnish (i) to each Person who at any time during such
calendar year was a Certificateholder of record and (ii) to any Person who at
any time during such calendar year was a Certificate Owner who has made a valid
Certificate Owner Request and provided the Pass Through Trustee with such
pertinent information as the Pass Through Trustee shall reasonably request, a
statement containing the sum of the amounts determined pursuant to clauses
(a)(i) and (a)(ii) with respect to the Pass Through Trust for such calendar
year or, in the event such Person was a Certificateholder of record or
Certificate Owner during a portion of such calendar year, for the applicable
portion of such year, and such other items as are readily available to the Pass
Through Trustee and which a Certificateholder or Certificate Owner shall
reasonably request as necessary for the purpose of such Certificateholder's or
Certificate Owner's preparation of its Federal income tax returns.

          (c)      Based on information provided by the Facility Lessees, if
there shall occur any change in the principal amortization schedule of the
Lessor Notes resulting in a change in the schedule of expected distributions on
the Certificates from that set forth on page 31 of the Offering Circular, the
Pass Through Trustee shall promptly furnish to the Certificateholders a
statement setting forth the revised principal amortization schedule of the
Lessor Notes and the resulting revised schedule of expected distributions on
the Certificates.

  Section 4.4 Investment of Special Payment Moneys. Any money received by the
Pass Through Trustee pursuant to Section 4.1(b) representing a Special Payment
which is not to be promptly distributed shall, to the extent practicable, be
invested in Permitted Government Investments by the Pass Through Trustee pending
distribution of such Special Payment pursuant to Section 4.2. Any investment
made pursuant to this Section 4.4 shall be in such Permitted Government
Investments having maturities not later than the date that such moneys are
required to be paid to make the payment required under Section 4.2 on the
applicable Special Distribution Date and the Pass Through Trustee shall hold any
such Permitted Government Investments until maturity. The Pass Through Trustee
shall have no liability with respect to any investment made pursuant to this
Section 4.4, other than by reason of the willful misconduct or negligence of the
Pass Through Trustee. All income and earnings from such investments shall be
distributed on such Special Distribution Date as part of such Special Payment.

          Lessees.

SECTION 6.   DEFAULT

  Section 6.1 Events of Default.

          (a)      With respect to any Lessor Note, if any Lease Indenture
Event of Default under the applicable Collateral Trust Indenture (an "Event of
Default") shall occur and be continuing, then, and in each and every case, so
long as such Lease Indenture Event of Default shall be continuing, the Pass
Through Trustee may vote all of the Lessor Notes issued under the Collateral
Trust Indenture held in the Pass Through Trust, and upon the Direction of the
Holders of Certificates evidencing Fractional Undivided Interests aggregating
not less than a majority in interest of the Fractional Undivided Interests
evidenced by all Certificates at the time Outstanding (determined as provided
in Section 1.4(c)), the Pass Through Trustee shall vote all of such Lessor
Notes, in favor of directing the applicable Indenture Trustee to declare the
unpaid principal amount of such Lessor Notes then outstanding and accrued
interest thereon to be due

                                       26

<PAGE>

and payable under, and to the extent permitted by and in accordance with, the
provisions of such Collateral Trust Indenture. In addition, with respect to any
Lessor Note, if a Lease Indenture Event of Default shall have occurred and be
continuing under the related Lease Indenture, the Pass Through Trustee may in
its discretion, and upon the Direction of the Holders of Certificates
evidencing Fractional Undivided Interest aggregating not less than a majority
in interest of the Fractional Undivided Interests evidenced by all Certificates
at the time Outstanding (determined as provided in Section 1.4(c)) as provided
in Section 6.4 shall, in accordance with such Collateral Trust Indenture vote
the applicable Lessor Notes issued thereunder held in the Pass Through Trust to
direct the applicable Indenture Trustee regarding the exercise of remedies
provided in such Collateral Trust Indenture and consistent with the terms
thereof. Notwithstanding the foregoing, no Lease Indenture Event of Default
under a given Collateral Trust Indenture shall give rise to a Lease Indenture
Event of Default under any other Collateral Trust Indenture.

          In addition, after an Event of Default shall have occurred and be
continuing, the Pass Through Trustee may in its discretion, and upon the
Direction of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest of the Fractional
Undivided Interests evidenced by all Certificates at the time Outstanding
(determined as provided in Section 1.4(c)) shall, by such officer or agent as
it may appoint, sell, convey, transfer and deliver all or a portion of such
Lessor Note or Lessor Notes issued under the Collateral Trust Indenture with
respect to which the Event of Default has occurred, without recourse to or
warranty by the Pass Through Trustee or any Certificateholders to any Person.
In any such case, the Pass Through Trustee shall sell, assign, contract to sell
or otherwise dispose of and deliver such Lessor Note or Lessor Notes in one or
more parcels at public or private sale or sales, at any location or locations
at the option of the Pass Through Trustee, all upon such terms and conditions
as it may reasonably deem advisable and at such prices as it may reasonably
deem advisable, for cash. The Pass Through Trustee shall give notice to the
applicable Facility Lessee and Owner Lessor promptly after any such sale.

          In the event that the Pass Through Trustee shall deem it advisable
to sell any or all of the Lessor Notes in accordance with the provisions of
this Section, the parties agree that if registration of any such Lessor Notes
shall be required, in the opinion of counsel for the Pass Through Trustee under
the Securities Act of 1933, as amended, or other applicable law, and
regulations promulgated thereunder, and if the Facility Lessees shall not
effect, or cause to be effected, such registration promptly, the Pass Through
Trustee may sell any such Lessor Notes at a private sale, and no Person shall
attempt to maintain that the prices at which such Lessor Notes are sold are
inadequate by reason of the failure to sell at public sale, or hold the Pass
Through Trustee liable thereafter.

     Section 6.2   Incidents of Sale of Lessor Notes. Upon any sale of all or
any part of the Lessor Notes made either under the power of sale given under
this Pass Through Trust Agreement or otherwise for the enforcement of this Pass
Through Trust Agreement, the following shall be applicable:

          (1)      Certificateholders and Pass Through Trustee May Purchase
     Lessor Notes. Any Certificateholder, the Pass Through Trustee in its
     individual or any other capacity or any other Person may bid for and
     purchase any of the Lessor Notes and, upon compliance

                                       27

<PAGE>

     with the terms of sale, may hold, retain, possess and dispose of such
     Lessor Notes in their or its or his own absolute right without further
     accountability.

          (2)      Receipt of Pass Through Trustee Shall Discharge Purchaser.
     The receipt of immediately available funds by the Pass Through Trustee or
     the officer or agent appointed by the Pass Through Trustee shall be a
     sufficient discharge to any purchaser for his purchase money, and, after
     paying such purchase money and receiving such receipt, such purchaser or
     his personal representative or assigns shall not be obliged to see to the
     application of such purchase money, or be in any way answerable for any
     loss, misapplication or non-application thereof.

          (3)      Application of Moneys Received upon Sale. Any moneys
     collected by the Pass Through Trustee, upon any sale made either under the
     power of sale given by this Pass Through Trust Agreement or otherwise for
     the enforcement of this Pass Through Trust Agreement, shall be applied as
     provided in Section 4.2.

     Section 6.3   Judicial Proceedings Instituted by Pass Through Trustee.

             (a) Pass Through Trustee May Bring Suit. If there shall be a
failure to make payment of the principal of, premium, if any, or interest on any
Lessor Note, or if there shall be any failure to pay Rent (as defined in a
Lease) under the Lease related to any Lessor Note when due and payable, then the
Pass Through Trustee, in its own name, and as trustee of an express trust, as
holder of such Lessor Notes shall be, to the extent permitted by and in
accordance with the terms of the Operative Documents, entitled and empowered
(but not obligated) to institute any suits, actions or proceedings at law, in
equity or otherwise, for the collection of the sums so due and unpaid on such
Lessor Notes or under such Lease and may prosecute any such claim or proceeding
to judgment or final decree with respect to the whole amount of any such sums so
due and unpaid; subject, however, to the limitations of liability set forth in
the Lessor Notes and the Operative Documents.

             (b) Pass Through Trustee May File Proofs of Claim; Appointment of
Pass Through Trustee as Attorney-in-Fact in Judicial Proceedings. The Pass
Through Trustee in its own name, or as trustee of an express trust, or as
attorney-in-fact for the Certificateholders, or in any one or more of such
capacities (irrespective of whether distributions on the Certificates shall then
be due and payable, or the payment of the principal on any Lessor Notes shall
then be due and payable, as therein expressed or by declaration or otherwise and
irrespective of whether the Pass Through Trustee shall have made any demand to
the applicable Indenture Trustee for the payment of overdue principal, premium
(if any) or interest on any Lessor Notes), shall, subject to the terms of the
Operative Documents, be entitled and empowered to file such proofs of claim and
other papers or documents as may be necessary or advisable in order to have the
claims of the Pass Through Trustee and of the Certificateholders allowed in any
receivership, insolvency, bankruptcy, liquidation, readjustment, reorganization
or any other judicial proceedings relative to any Facility Lessee, any Owner
Lessor, any Lessor Manager or any Owner Participant, or their respective
creditors or property. Subject to the terms of the Operative Documents, any
receiver, assignee, trustee, liquidator or sequestrator (or similar official) in
any such judicial proceeding is hereby authorized by each Certificateholder to
make payments in respect of such claim to the Pass Through Trustee, and in the
event that the Pass Through Trustee shall consent to the making

                                       28

<PAGE>

of such payments directly to the Certificateholders, to pay to the Pass Through
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Pass Through Trustee, its agents and counsel
and any other amounts due the Pass Through Trustee under Section 7.7. Subject
to Section 6.4, nothing contained in this Pass Through Trust Agreement shall be
deemed to give to the Pass Through Trustee any right to accept or consent to
any plan of reorganization or otherwise by action of any character in any such
proceeding to waive or change in any way any right of any Certificateholder.

     Section 6.4   Control by Certificateholders. The Holders of Certificates
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest of the Fractional Undivided Interests evidenced by all Certificates
at the time Outstanding (determined as provided in Section 1.4(c)) shall have
the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Pass Through Trustee, or exercising any trust or
power conferred upon the Pass Through Trustee, under this Pass Through Trust
Agreement, including any right of the Pass Through Trustee as holder of the
Lessor Notes, provided that:

             (1) such Direction shall not be in conflict with any rule of law or
     with this Pass Through Trust Agreement and would not involve the Pass
     Through Trustee in personal liability or expense;

             (2) the Pass Through Trustee shall not determine that the action so
     directed would expose it to personal liability or be unjustly prejudicial
     to the Certificateholders not taking part in such Direction;

             (3) the Pass Through Trustee may take any other action deemed
     proper by the Pass Through Trustee which is not inconsistent with such
     Direction;

             (4) such Holders shall have offered to the Pass Through Trustee
     security or indemnity against the costs, expenses or liabilities which may
     be incurred thereby; and

             (5) if a Lease Indenture Event of Default shall have occurred and
     be continuing, such Direction shall not obligate the Pass Through Trustee
     to vote more than a corresponding majority of the related Lessor Notes held
     by the Pass Through Trust in favor of directing any action by the
     applicable Indenture Trustee with respect to such Lease Indenture Event of
     Default.

     Section 6.5   Waiver of Defaults. The Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than a majority in interest
of the Fractional Undivided Interests evidenced by all Certificates at the time
Outstanding (determined as provided in Section 1.4(c)) may on behalf of the
Certificateholders of all the Certificates waive any Default hereunder and its
consequences or may instruct the Pass Through Trustee to waive any default
under a Collateral Trust Indenture and its consequences, except:

             (1) a default in the deposit of any Scheduled Payment or Special
     Payment under Section 4.1 or in the distribution of any payment under
     Section 4.2 on the Certificates; or

                                       29

<PAGE>

          (2) a default in the payment of the principal of, premium, if any, or
     interest on any Lessor Notes; or

          (3) a default in respect of a covenant or provision hereof which under
     Section 9 hereof cannot be modified or amended without the consent of the
     Holder of each Outstanding Certificate affected.

          Upon any such waiver, such Default shall cease to exist with
respect to this Pass Through Trust Agreement, and any Event of Default arising
therefrom shall be deemed to have been cured for every purpose of this Pass
Through Trust Agreement and any direction given by the Pass Through Trustee on
behalf of such Holders to the applicable Indenture Trustee shall be annulled
with respect thereto; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon. Upon
any such waiver with respect to a Default under a Collateral Trust Indenture,
the Pass Through Trustee shall vote a corresponding majority of the Lessor
Notes issued under the applicable Collateral Trust Indenture to waive the
corresponding Lease Indenture Default or Lease Indenture Event of Default.

          With respect to consents, approvals, waivers and authorizations
which under the terms of Section 9 of a Collateral Trust Indenture may be given
by the applicable Indenture Trustee without the necessity of the consent of any
of the holders of Lessor Notes issued with respect to such Collateral Trust
Indenture, no consent, approval, waiver or authorization shall be required
hereunder on the part of the Pass Through Trustee or the Certificateholders.

     Section 6.6 Undertaking to Pay Court Costs. All parties to this Pass
Through Trust Agreement, and each Certificateholder by his acceptance of a
Certificate, shall be deemed to have agreed that any court may in its discretion
require, in any suit, action or proceeding for the enforcement of any right or
remedy under this Pass Through Trust Agreement, or in any suit, action or
proceeding against the Pass Through Trustee for any action taken or omitted by
it as Pass Through Trustee hereunder, the filing by any party litigant in such
suit, action or proceeding of an undertaking to pay the costs of such suit,
action or proceeding, and that such court may, in its discretion, assess
reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, action or proceeding, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; provided,
however, that the provisions of this Section 6.6 shall not apply to (a) any
suit, action or proceeding instituted by any Holder, or group of Holders,
holding in the aggregate Certificates evidencing Fractional Undivided Interests
aggregating more than 10% of the Pass Through Trust, (b) any suit, action or
proceeding instituted by any Certificateholder for the enforcement of the
distribution of payments pursuant to Section 4.2 hereof on or after the
respective due dates expressed herein or (c) any suit, action or proceeding
instituted by the Pass Through Trustee.

     Section 6.7 Right of Certificateholders to Receive Payments Not to Be
Impaired. Anything in this Pass Through Trust Agreement to the contrary
notwithstanding, but subject to Section 3.8 hereof, the right of any
Certificateholder to receive distributions of payments required pursuant to
Section 4.2 hereof on the Certificates when due, or to institute suit for the
enforcement of any such payment on or after the applicable Distribution Date or
Special Distribution Date, shall not be impaired or affected without the consent
of such Certificateholder.

                                       30

  Section 6.8 Certificateholders May Not Bring Suit Except Under Certain
Conditions. A Certificateholder shall not have the right to institute any suit,
action or proceeding at law or in equity or otherwise with respect to this Pass
Through Trust Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Pass Through Trust Agreement, unless:

          (1)      such Certificateholder previously shall have given written
      notice to the Pass Through Trustee of a continuing Event of Default;

          (2)      the Holders of Certificates evidencing Fractional Undivided
     Interests aggregating not less than a majority in interest of the
     Fractional Undivided Interests evidenced by all Certificates at the time
     Outstanding (determined as provided in Section 1.4(c)) shall have
     requested the Pass Through Trustee in writing to institute such suit,
     action or proceeding and shall have offered to the Pass Through Trustee
     indemnity as provided in Section 7.3(e);

          (3)      the Pass Through Trustee shall have refused or neglected to
     institute any such suit, action or proceeding for 60 days after receipt
     of such notice, request and offer of indemnity; and

          (4)      no Direction inconsistent with such written request has been
     given to the Pass Through Trustee during such 60-day period by the
     Holders of Certificates evidencing Fractional Undivided Interests
     aggregating not less than a majority in interest of the Fractional
     Undivided Interests evidenced by all Certificates at the time Outstanding
     (determined as provided in Section 1.4(c)).

          It is understood and intended that no one or more of the
Certificateholders shall have any right in any manner whatever hereunder or
under the Certificates to (i) surrender, impair, waive, affect, disturb or
prejudice any property in the Trust Property or the lien of any Collateral
Trust Indenture on any property subject thereto, or the rights of the
Certificateholders or the holders of the Lessor Notes, (ii) obtain or seek to
obtain priority over or preference to any other such Holder, or (iii) enforce
any right under this Pass Through Trust Agreement, except in the manner herein
provided and for the equal, ratable and common benefit of all the
Certificateholders subject to the provisions of this Pass Through Trust
Agreement.

     Section 6.9   Remedies Cumulative. Every remedy given hereunder to the Pass
Through Trustee or to any of the Certificateholders shall not be exclusive of
any other remedy or remedies, and every such remedy shall be cumulative and in
addition to every other remedy given hereunder or now or hereafter given by
statute, law, equity or otherwise.

SECTION 7.   THE PASS THROUGH TRUSTEE

  Section 7.1 Certain Duties and Responsibilities.

          (a)      Prior to an Event of Default of which a Responsible Officer
of the Pass Through Trustee has actual knowledge:

<PAGE>

          (1)      the Pass Through Trustee shall not be liable except for the
     performance of such duties as are specifically set out in this Pass
     Through Trust Agreement; and

          (2)      the Pass Through Trustee may conclusively rely, as to the
     truth of the statements and the correctness of the opinions expressed
     therein, in the absence of bad faith on the part of the Pass Through
     Trustee, upon Officer's Certificates or Opinions of Counsel conforming to
     the requirements of this Pass Through Trust Agreement;

but the Pass Through Trustee shall, at any time that the Certificates shall be
subject to the Trust Indenture Act, examine any evidence furnished to it
pursuant to this Pass Through Trust Agreement or Section 314 of the Trust
Indenture Act to determine whether or not such evidence conforms to the
requirements of this Pass Through Trust Agreement; provided, however, that the
Pass Through Trustee shall not be responsible for the accuracy or content of
such evidence.

          (b)      In case an Event of Default has occurred and is continuing,
the Pass Through Trustee shall exercise each of the rights and powers vested in
it by this Pass Through Trust Agreement and use the same degree of care and
skill in its exercise, as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs.

          (c)      No provision of this Pass Through Trust Agreement shall be
construed to relieve the Pass Through Trustee from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

          (1)      this paragraph (c) shall not be construed to limit the
     effect of paragraph (a) of this Section 7.1;

          (2)      the Pass Through Trustee shall not be liable in its
     individual capacity for any error of judgment made in good faith by a

     facts; and

          (3)      the Pass Through Trustee shall not be liable with respect to
     any action taken or omitted to be taken by it in good faith in accordance

     the Fractional Undivided Interests evidenced by all Certificates at the
     time Outstanding (determined as provided in Section 1.4(c)) (A) relating
     to the time, method and place of conducting any proceeding for any remedy
     available to the Pass Through Trustee, or (B) exercising any trust or
     power conferred upon the Pass Through Trustee, under this Pass Through

          (d)      Whether or not herein expressly so provided, every provision

accordance with Section 12.3, notice of all Defaults actually known to a
Responsible Officer of the Pass Through Trustee within 90 days after the
occurrence thereof; provided, however, that, except in the case of a Default in

Note, the Pass Through Trustee shall be protected in withholding such notice if
and so long as the board of directors, the executive committee or a trust
committee of directors or Responsible Officers of the Pass Through Trustee in
good faith determine that the withholding of such notice is in the interests of
the Certificateholders.

believed by it to be genuine and to have been signed or presented by the proper
party or parties;

          (b)      any request or direction of any of the Facility Lessees, an
Owner Lessor or any Indenture Trustee mentioned herein shall be sufficiently

          (c)      whenever in the administration of this Pass Through Trust
Agreement the Pass Through Trustee shall deem it desirable that a matter be

offered to the Pass Through Trustee reasonable security or indemnity against
the cost, expenses and liabilities which might be incurred by it in compliance
with such request or direction;

          (f)      the Pass Through Trustee shall not be bound to make any

any action taken, suffered or omitted by it in good faith and believed by it to
be authorized or within the discretion of rights or powers conferred upon it by

the Operative Documents, or the Certificates, or the collateral securing the
Lessor Notes, except that the Pass Through Trustee hereby represents and
warrants that this Pass Through Trust Agreement has been, and each Certificate
will be, executed and delivered by one of its officers who is duly authorized to
execute and deliver such document on its behalf.

  Section 7.5 May Hold Certificates. The Pass Through Trustee, any Paying Agent,
Registrar or any other agent, in their respective individual or any other
capacity, may become the owner or pledgee of Certificates and may otherwise deal
with any Facility Lessee, any Owner Lessor, any Owner Participant or any

          (1)      to pay, or cause to be paid, to the Pass Through Trustee from
     time to time the compensation separately agreed to by the Pass Through

<PAGE>

          (2)      except as otherwise expressly provided herein, to reimburse,
     or cause to be reimbursed, the Pass Through Trustee upon its request for
     all reasonable out-of-pocket expenses, disbursements and advances incurred
     or made by the Pass Through Trustee in accordance with any provision of
     this Pass Through Trust Agreement (including the reasonable compensation
     and the expenses and disbursements of its agents and counsel), except any

reimbursement from, and shall have a lien prior to the Certificates upon, all
property and funds held or collected by the Pass Through Trustee in its
capacity as Pass Through Trustee for any tax incurred without negligence, bad

including any costs and expenses incurred in contesting the imposition of any
such tax. If the Pass Through Trustee reimburses itself for any such tax, it
will within 30 days mail a brief report setting forth the circumstances thereof
to all Certificateholders as their names and addresses appear in the Register.

act as a trustee under Section 310(a) of the Trust Indenture Act and (b) shall
be a corporation organized and doing business under the laws of the United
States of America or of any state, authorized under such laws to exercise
corporate trust powers, having a combined capital and surplus of at least
$150,000,000, and subject to supervision or examination by Federal or state
authority. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section 7.8, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Pass Through Trustee shall cease to be eligible in accordance with
the provisions of clause (a) of this Section 7.8 at a time when it is required
to be so qualified, it shall resign immediately in the manner and with the
effect hereinafter specified in this Section 7.

  Section 7.9 Resignation and Removal: Appointment of Successor.

          (a)      No resignation or removal of the Pass Through Trustee and no

Pass Through Trustee under Section 7.10.

          (b)      The Pass Through Trustee may resign at any time by giving
written notice thereof to the Facility Lessees, the Authorized Agents, the
Owner Lessors, the Owner Participants and each Indenture Trustee. If an
instrument of acceptance by a successor Pass Through Trustee shall not have
been delivered to the Facility Lessees, the Owner Lessors, the Owner
Participants and each Indenture Trustee within 30 days after the giving of such
notice of resignation, the resigning Pass Through Trustee may petition any
court of competent jurisdiction for the appointment of a successor Pass Through
Trustee.

                                       35

<PAGE>

          (c)      The Pass Through Trustee may be removed at any time by Act of
the Holders holding Certificates evidencing Fractional Undivided Interests
aggregating not less than a majority in interest in the Pass Through Trust
delivered to the Pass Through Trustee and to the Facility Lessees, the Owner
Lessors and each Indenture Trustee.

          (d)      If at any time:

                   (1)      the Pass Through Trustee fails to, at any time that
          the Certificates shall be subject to the Trust Indenture Act, comply
          with the requirements of Section 310 of the Trust Indenture Act after
          written request for such compliance by a Certificateholder that has
          been a bona fide Certificateholder for at least six months; or

                   (2)      the Pass Through Trustee shall cease to be eligible
          under Section 7.8 hereof and shall fail to resign after written
          request therefor by the Facility Lessees (or, following the
          occurrence and during the continuation of a Lease Event of Default,
          the applicable Owner Lessor) or by any such Certificateholder; or

                   (3)      the Pass Through Trustee shall become incapable of
          acting or shall be adjudged bankrupt or insolvent or a receiver of
          the Pass Through Trustee or of its property shall be appointed or any
          public officer shall take charge or control of the Pass Through
          Trustee or of its property or affairs for the purpose of
          rehabilitation, conservation or liquidation;

then, in any case, (i) the Facility Lessees (or, following the occurrence and
during the continuation of a Lease Event of Default, the applicable Owner
Lessor) may remove the Pass Through Trustee or (ii) subject to Section 6.6
hereof, any Certificateholder who has been a bona fide Holder of a Certificate
for at least six months may, on behalf of himself and all others similarly
situated, petition any court of competent jurisdiction for the removal of the
Pass Through Trustee and the appointment of a successor Pass Through Trustee.

          (e)      If a Responsible Officer of the Pass Through Trustee shall
obtain Actual Knowledge of an Avoidable Tax (as hereinafter defined) which has
been or is likely to be asserted, the Pass Through Trustee shall promptly
notify the Facility Lessees and the applicable Owner Lessor thereof and shall,
within 30 days of such notification, resign hereunder unless within such 30-day
period the Pass Through Trustee shall have received notice that the Facility
Lessees or the applicable Owner Lessor has agreed to pay such tax. The Facility
Lessees shall promptly appoint a successor Pass Through Trustee in a
jurisdiction where there are no Avoidable Taxes. As used herein an "Avoidable
Tax" means a state or local tax: (i) upon (w) the Pass Through Trust, (x) the
Trust Property, (y) Holders of the Certificates or (z) the Pass Through Trustee
for which the Pass Through Trustee is entitled to seek reimbursement from the
Trust Property, and (ii) that would be avoided if the Pass Through Trustee were
located in another state, or jurisdiction within a state, within the United
States. A tax shall not be an Avoidable Tax if the Facility Lessees or the
Owner Lessors shall agree to pay, and shall pay, such tax.

                                       36

<PAGE>

          (f)      If the Pass Through Trustee shall resign, be removed or
become incapable of acting, or if a vacancy shall occur in the office of the
Pass Through Trustee for any cause, the Facility Lessees (or, following the
occurrence of a Lease Event of Default, the applicable Owner Lessor) shall
promptly appoint a successor Pass Through Trustee. If, within one year after
such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Pass Through Trustee shall be appointed by Act of the Holders holding
Certificates evidencing Fractional Undivided Interests aggregating not less
than a majority in interest in the Pass Through Trust, delivered to the
Facility Lessees, the Owner Lessors, the Owner Participants, the Indenture
Trustees and the retiring Pass Through Trustee, the successor Pass Through
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Pass Through Trustee and supersede the successor Pass
Through Trustee appointed as provided above. If no successor Pass Through
Trustee shall have been so appointed as provided above and accepted such
appointment in the manner hereinafter provided, any Certificateholder who has
been a bona fide Holder of a Certificate for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the appointment of a successor Pass Through Trustee.

          (g)      The successor Pass Through Trustee shall give notice of the
resignation and removal of the Pass Through Trustee and appointment of the
successor Pass Through Trustee by mailing written notice of such event by
first-class mail, postage prepaid, to the Holders of Certificates as their
names and addresses appear in the Register. Each notice shall include the name
of such successor trustee and the address of its Corporate Trust Office.

  Section 7.10 Acceptance of Appointment by Successor. Every successor Pass
Through Trustee appointed hereunder shall execute, acknowledge and deliver to
the Facility Lessees, the Owner Lessors and to the retiring Pass Through Trustee
an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Pass Through Trustee shall become effective and such
successor Pass Through Trustee, without any further act, deed or conveyance,
shall become vested with all the rights, powers, trusts and duties of the
retiring Pass Through Trustee; but, on request of any Facility Lessee (or,
following the occurrence of a Lease Event of Default, the applicable Owner
Lessor) to the successor Pass Through Trustee, such retiring Pass Through
Trustee shall execute and deliver an instrument transferring to such successor
Pass Through Trustee all the rights, powers and trusts of the retiring Pass
Through Trustee and shall duly assign, transfer and deliver to such successor
Pass Through Trustee all property and money held by such retiring Pass Through
Trustee hereunder, subject nevertheless to its lien, if any, provided for in
Section 7.7. Upon request of any such successor Pass Through Trustee, the
Facility Lessees, the Owner Lessors, the retiring Pass Through Trustee and such
successor Pass Through Trustee shall execute and deliver any and all instruments
containing such provisions as shall be necessary or desirable to transfer and
confirm to, and for more fully and certainly vesting in, such successor Pass
Through Trustee all such rights, powers and trusts.

          No successor Pass Through Trustee shall accept its appointment
unless at the time of such acceptance such successor Pass Through Trustee shall
be qualified and eligible under this Section 7.

  Section 7.11 Merger, Conversion, Consolidation or Succession to Business. Any
Person into which the Pass Through Trustee may be merged or converted or with
which it may

                                       37

<PAGE>

be consolidated, or any Person resulting from any merger, conversion or
consolidation to which the Pass Through Trustee shall be a party, or any Person
succeeding to all or substantially all of the corporate trust business of the
Pass Through Trustee, shall be the successor of the Pass Through Trustee
hereunder, provided such Person shall be otherwise qualified and eligible under
this Section 7, without the execution or filing of any paper or any further act
on the part of any of the parties hereto. In case any Certificates shall have
been authenticated, but not delivered, by the Pass Through Trustee then in
office, any successor by merger, conversion or consolidation to such
authenticating Pass Through Trustee may adopt such authentication and deliver
the Certificates so authenticated with the same effect as if such successor
Pass Through Trustee had itself authenticated such Certificates.

  Section 7.12 Maintenance of Agencies.

          (a)      There shall at all times be maintained in the Borough of
Manhattan, The City of New York, an office or agency where Certificates may be
presented or surrendered for registration of transfer or for exchange, and for
payment thereof and where notices and demands to or upon the Pass Through
Trustee in respect of the Certificates or of this Pass Through Trust Agreement
may be served. Written notice of the location of each such other office or
agency and of any change of location thereof shall be given by the Pass Through
Trustee to the Facility Lessees, the Owner Lessors, the Owner Participants,
each Indenture Trustee and the Certificateholders. In the event that no such
office or agency shall be maintained or no such notice of location or of change
of location shall be given, presentations and demands may be made and notices
may be served at the Corporate Trust Office of the Pass Through Trustee.

          (b)      There shall at all times be a Registrar and a Paying Agent
hereunder. Each such Authorized Agent shall be a bank or trust company, shall
be a corporation organized and doing business under the laws of the United
States or any state, with a combined capital and surplus of at least
$150,000,000, and shall be authorized under such laws to exercise corporate
trust powers, subject to supervision by Federal or state authorities. The Pass
Through Trustee shall initially be the Paying Agent and, as provided in Section
3.4, Registrar hereunder. Each Registrar shall furnish to the Pass Through
Trustee (unless they are the same entity), at stated intervals of not more than
six months, and at such other times as the Pass Through Trustee may request in
writing, a copy of the Register.

          (c)      Any Person into which any Authorized Agent may be merged or
converted or with which it may be consolidated, or any Person resulting from
any merger, consolidation or conversion to which any Authorized Agent shall be
a party, or any Person succeeding to the corporate trust business of any
Authorized Agent, shall be the successor of such Authorized Agent hereunder, if
such successor Person is otherwise eligible under this Section 7.12, without
the execution or filing of any paper or any further act on the part of the
parties hereto or such Authorized Agent or such successor Person.

          (d)      Any Authorized Agent may at any time resign by giving written
notice of resignation to the Pass Through Trustee, the Facility Lessees, the
Owner Lessors, the Owner Participants and each Indenture Trustee. The Facility
Lessees (or, following the occurrence of a Lease Event of Default, the Owner
Lessor) may, and at the request of the Pass Through Trustee shall, at any time
terminate the agency of any Authorized Agent by giving written notice of

                                       38

<PAGE>

termination to such Authorized Agent and to the Pass Through Trustee. Upon the
resignation or termination of an Authorized Agent or in case at any time any
such Authorized Agent shall cease to be eligible under this Section 7.12 (when,
in either case, no other Authorized Agent performing the functions of such
Authorized Agent shall have been appointed), the Facility Lessees (or,
following the occurrence of a Lease Event of Default, the applicable Owner
Lessor) shall promptly appoint one or more qualified successor Authorized
Agents reasonably satisfactory to the Pass Through Trustee, to perform the
functions of the Authorized Agent which has resigned or whose agency has been
terminated or who shall have ceased to be eligible under this Section 7.12. The
Facility Lessees (or, following the occurrence of a Lease Event of Default, the
applicable Owner Lessor) shall give written notice of any such appointment made
by it to the Pass Through Trustee, the Facility Lessees, the Owner Lessors and
each Indenture Trustee; and in each case the Pass Through Trustee shall mail
notice of such appointment to all Holders as their names and addresses appear
on the Register.

          (e)      Each Facility Lessee agrees to pay, or cause to be paid, from
time to time to each Authorized Agent the compensation as set forth in the
schedule agreed to by each Authorized Agent and such Facility Lessee for its
services and to reimburse it for its reasonable expenses.

  Section 7.13 Money for Certificate Payments to Be Held in Trust. All moneys
deposited with any Paying Agent for the purpose of any payment on Certificates
shall be deposited in a non interest bearing account and held in trust for the
benefit of the Holders of the Certificates entitled to such payment, subject to
the provisions of this Section 7.13. Moneys so deposited and held in trust shall
constitute a separate trust fund for the benefit of the Holders of the
Certificates with respect to which such money was deposited.

          The Pass Through Trustee will cause each Paying Agent other than
the Pass Through Trustee to execute and deliver to it an instrument in which
such Paying Agent shall agree with the Pass Through Trustee, subject to the
provisions of this Section 7.13, that such Paying Agent will:

          (1)      hold all sums held by it for payments on
     Certificates in trust for the benefit of the Persons entitled
     thereto until such sums shall be paid to such Persons or
     otherwise disposed of as herein provided;

          (2)   give the Pass Through Trustee notice in writing of any default
     by any obligor upon the Certificates in the making of any such payment;
     and

          (3)   at any time during the continuance of any such default, upon the
     written request of the Pass Through Trustee, forthwith pay to the Pass
     Through Trustee all sums so held in trust by such Paying Agent.

          The Pass Through Trustee may at any time, for the purpose of
obtaining the satisfaction and discharge of this Pass Through Trust Agreement
or for any other purpose, direct any Paying Agent to pay to the Pass Through
Trustee all sums held in trust by such Paying Agent, such sums to be held by
the Pass Through Trustee upon the same trusts as those upon which such sums
were held by such Paying Agent; and, upon such payment by any Paying Agent

                                       39

<PAGE>

to the Pass Through Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

     Section 7.14  Registration of Lessor Notes in Pass Through Trustee's Name
The Pass Through Trustee agrees that all Lessor Notes and Permitted Government
Investments, if any, shall be issued in the name of the Pass Through Trustee or
its nominee and held by the Pass Through Trustee, or, if not so held, the Pass
Through Trustee or its nominee shall be reflected as the owner of such Lessor
Notes or Permitted Government Investments, as the case may be, in the register
of the issuer of such Lessor Notes or Permitted Government Investments under
the applicable provisions of the Uniform Commercial Code in effect where the
Pass Through Trustee holds such Lessor Notes or Permitted Government
Investments, or other applicable law then in effect.

     Section 7.15  Withholding Taxes; Information Reporting. The Pass Through
Trustee, as trustee, shall exclude and withhold from each distribution of
principal, premium, if any, and interest and other amounts due hereunder or
under the Certificates any and all withholding taxes applicable thereto as
required by law. The Pass Through Trustee agrees (i) to act as such withholding
agent and, in connection therewith, whenever any present or future taxes or
similar charges are required to be withheld with respect to any amounts payable
in respect of the Certificates, to withhold such amounts and timely pay the
same to the appropriate authority in the name of and on behalf of the Holders
of the Certificates, (ii) that it will file any necessary withholding tax
returns or statements when due, and (iii) that, as promptly as possible after
the payment thereof, it will deliver to each Holder of a Certificate
appropriate documentation showing the payment thereof, together with such
additional documentary evidence as such Holders may reasonably request from
time to time. The Pass Through Trustee agrees to file any other information
reports as it may be required to file under United States law. Any amounts
withheld and paid to a relevant taxing authority pursuant to this Section 7.15
shall be deemed to have been paid to the related Certificateholders for all
purposes under the Operative Documents.

     Section 7.16  Pass Through Trustee's Liens. The Pass Through Trustee, in
its individual capacity, agrees that it will at its own cost and expense
promptly take any action as may be necessary to duly discharge and satisfy in
full any mortgage, pledge, lien, charge, encumbrance, security interest or
claim on or with respect to the Trust Property which is either (i) attributable
to the Pass Through Trustee in its individual capacity and which is unrelated
to the transactions contemplated by this Pass Through Trust Agreement or any
other applicable Operative Document, or (ii) which is attributable to the Pass
Through Trustee as trustee hereunder or in its individual capacity and which
arise out of acts or omissions which are prohibited by this Pass Through Trust
Agreement.

SECTION 8.   CERTIFICATEHOLDERS' LISTS AND REPORTS

     Section 8.1   The Facility Lessees to Furnish Pass Through Trustee with
Names and Addresses of Certificateholder. Each Facility Lessees will furnish to
the Pass Through Trustee within fifteen days after each Record Date with
respect to a Scheduled Payment, and at such other times as the Pass Through
Trustee may request in writing, a list, in such form as the Pass Through
Trustee may reasonably require, of all information in the possession or control
of such Facility Lessee as to the names and addresses of the Holders of
Certificates, in each case as of a

                                       40

<PAGE>

date not more than sixty days prior to the time such list is furnished;
provided, however, that so long as the Pass Through Trustee is the sole
Registrar, no such list need be furnished; and provided, further, however, that
no such list need be furnished for so long as a copy of the Register is being
furnished to the Pass Through Trustee pursuant to Section 7.12(b).

     Section 8.2   Preservation of Information. The Pass Through Trustee shall
preserve, in as current a form as is reasonably practicable, the names and
addresses of Holders of Certificates contained in the most recent list
furnished to the Pass Through Trustee as provided in Section 7.12(b) or Section
8.1, as the case may be, and the names and addresses of Holders of Certificates
received by the Pass Through Trustee in its capacity as Registrar, if so
acting. The Pass Through Trustee may destroy any list furnished to it as
provided in Section 7.12(b) or Section 8.1, as the case may be, upon receipt of
a new list so furnished.

     Section 8.3   Reports by the Facility Lessees. Each Facility Lessee shall,
at any time that the Certificates shall be subject to the Trust Indenture Act,
comply with Section 314 of the Trust Indenture Act and shall file, furnish and
deliver the reports, information, documents, certificates and opinions required
thereunder, and, at any time that the Certificates shall be subject to the
Trust Indenture Act, acknowledge and agree that, for purposes of Section 314 of
the Trust Indenture Act, each Facility Lessee shall be considered to be the
"obligor" upon the Certificates. Without limiting the generality of the
foregoing, at any time that the Certificates shall be subject to the Trust
Indenture Act, each Facility Lessee shall deliver to the Pass Through Trustee
the annual certificate required under clause (4) of Section 314(a) of the Trust
Indenture Act within 120 days following the end of each fiscal year of such
Facility Lessee (which ends on December 31) ending after the date hereof. The
provisions of this Section 8.3 shall not be construed to impose any obligation
or liability on the Facility Lessees to pay any of the principal, premium, if
any, or interest in respect of the Lessor Notes or the Certificates.

     Section 8.4   Reports by the Pass Through Trustee. At any time that the
Certificates shall be subject to the Trust Indenture Act, the Pass Through
Trustee shall transmit, on or before May 15 of each year, reports with respect
to events described in Section 313(a) of the Trust Indenture Act in accordance
with and to the extent required under Section 313(a) of the Trust Indenture
Act. Additionally, the Pass Through Trustee shall comply with the reporting
requirements imposed under Treasury Regulation 1.67.

SECTION 9.   SUPPLEMENTAL TRUST AGREEMENTS

     Section 9.1   Supplemental Trust Agreement Without Consent of
Certificateholders. Without the consent of the Holder of any Certificates, the
Facility Lessees may, and the Pass Through Trustee (subject to Section 9.3)
shall, at any time and from time to time enter into one or more agreements
supplemental hereto, in form satisfactory to the Pass Through Trustee, for any
of the following purposes:

             (1) to evidence the succession of another Person to any Facility
     Lessee and the assumption by any such successor of the obligations of such
     Facility Lessee herein contained;

                                       41

<PAGE>

             (2) to add to the covenants of the Facility Lessees, for the
     protection of the Holders of the Certificates;

             (3) to surrender any right or power herein conferred upon the
     Facility Lessees;

             (4) to cure any ambiguity, to correct or supplement any provision
     herein which may be defective or inconsistent with any other provision
     herein or to make any other provisions with respect to matters or questions
     arising under this Pass Through Trust Agreement; provided that any such
     action will not adversely affect in any material respect the interests of
     the Holders of the Certificates;

             (5) to correct or amplify the description of property that
     constitutes Trust Property or the conveyance of such property to the Pass
     Through Trustee;

             (6) to evidence and provide for a successor Pass Through Trustee;

             (7) to comply with requirements of the SEC, any applicable law,
     rules or regulations of any exchange or quotation system on which the
     Certificates are listed, or any regulatory body;

             (8) at any time that the Certificates shall be subject to the Trust
     Indenture Act, to modify, eliminate or add to the provisions of this Pass
     Through Trust Agreement to the extent as shall be necessary to qualify or
     continue the qualification of this Pass Through Trust Agreement (including
     any supplemental agreement) under the Trust Indenture Act (if such
     qualification is required) or under any similar Federal statute hereafter
     enacted, or to add to this Pass Through Trust Agreement such other
     provisions as may be expressly permitted by the Trust Indenture Act,
     excluding, however, the provisions referred to in Section 316(a)(2) of the
     Trust Indenture Act as in effect at the date as of which this instrument
     was executed or any corresponding provision in any similar Federal statute
     hereafter enacted;

             (9) to modify, amend or supplement any provision herein to reflect
     changes relating to the assumption and substitution of any Lessor Note
     pursuant to Section 2.10(b) of the Collateral Trust Indenture; or

             (10) to add, eliminate, or change any provision under this Pass
     Through Trust Agreement that will not adversely affect the interests of the
     Certificateholders in any material respect;

provided that in each case the Pass Through Trustee shall have received an
opinion of counsel, which may be counsel to the Facility Lessees, to the effect
that such supplemental agreement does not cause the Pass Through Trust to become
taxable as an "association" within the meaning of Treasury Regulation Section
301.7701-4 or to be taxable as other than a pass through entity for Federal
income tax purposes.

     Section 9.2   Supplemental Trust Agreements with Consent of
Certificateholders. With the consent of the Holders of Certificates evidencing
Fractional Undivided Interests aggregating not less than a majority in interest
of the Fractional Undivided Interests evidenced by all

                                       42

<PAGE>

Certificates at the time Outstanding (determined as provided in Section 1.4(c)
hereof), by Act of said Holders delivered to the Facility Lessees and the Pass
Through Trustee, the Facility Lessees may (with the consent of the Owner
Lessors, such consent not to be unreasonably withheld), and the Pass Through
Trustee (subject to Section 9.3 hereof) shall, enter into an agreement or
agreements supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Pass
Through Trust Agreement or of modifying in any manner the rights and
obligations of the Holders of the Certificates under this Pass Through Trust
Agreement; provided, however, that no such supplemental agreement shall,
without the consent of the Holder of each Outstanding Certificate affected
thereby:

          (1)      reduce in any manner the amount of, or delay the timing of,
     any receipt by the Pass Through Trustee of payments on the Lessor Notes
     held in the Pass Through Trust, or distributions that are required to be
     made herein on any Certificate of such Pass Through Trust, or change any
     date of payment on any such Certificate, or change the place of payment
     where, or the coin or currency in which, any such Certificate is payable,
     or impair the right of any Holder of any such Certificate to institute
     suit for the enforcement of any such payment or distribution on or after
     the Distribution Date or Special Distribution Date applicable thereto; or

          (2)      except as provided in this Pass Through Trust Agreement,
     permit the disposition of any Lessor Note in the Trust Property, or permit
     the creation of any lien on the Trust Property, or otherwise deprive any
     Certificateholder of the benefit of the ownership of the Lessor Notes held
     in the Pass Through Trust or the lien of the related Collateral Trust
     Indenture; or

          (3)      reduce the percentage of the aggregate Fractional Undivided
     Interests which is required to approve any such supplemental agreement, or
     reduce such percentage required for any waiver provided for in this Pass
     Through Trust Agreement.

Notwithstanding the foregoing, no such supplemental agreement shall be entered
into unless the Pass Through Trustee shall have received an opinion of counsel,
which may be counsel to the Facility Lessees or any of them, to the effect that
such supplemental agreement does not cause the Pass Through Trust to become
taxable as an "association", within the meaning of Treasury Regulation Section
301.7701-4 or to be taxable as other than a pass through entity for Federal
income tax purposes.

          It shall not be necessary for any Act of Certificateholders under
this Section 9.2 to approve the particular form of any proposed supplemental
agreement, but it shall be sufficient if such Act shall approve the substance
thereof.

  Section 9.3 Documents Affecting Immunity or Indemnity. If in the opinion of
the Pass Through Trustee any document required to be executed by it pursuant to
the terms of Section 9.1 or 9.2 affects any interest, right, duty, immunity or
indemnity in favor of the Pass Through Trustee under this Pass Through Trust
Agreement, the Pass Through Trustee may in its discretion decline to execute
such document.

                                       43

<PAGE>

     Section 9.4   Execution of Supplemental Trust Agreements. In executing, or
accepting the additional trusts created by, any supplemental agreement
permitted by this Section 9 or the modification thereby of the trusts created
by this Pass Through Trust Agreement, the Pass Through Trustee shall be
entitled to receive, and (subject to Section 7.1) shall be fully protected in
relying upon, an Opinion of Counsel stating that the execution of such
supplemental agreement is authorized or permitted by this Pass Through Trust
Agreement.

     Section 9.5   Effect of Supplemental Trust Agreements. Upon the execution
of any supplemental agreement under this Section 9, this Pass Through Trust
Agreement shall be modified in accordance therewith, and such supplemental
agreement shall form a part of this Pass Through Trust Agreement for all
purposes; and every Holder of Certificates theretofore or thereafter
authenticated and delivered hereunder shall be bound thereby.

     Section 9.6   Reference in Certificates to Supplemental Trust Agreements.
Certificates authenticated and delivered after the execution of any
supplemental agreement pursuant to this Section 9 may bear a notation in form
approved by the Pass Through Trustee as to any matter provided for in such
supplemental agreement; and, in such case, suitable notation may be made upon
Outstanding Certificates after proper presentation and demand.

     Section 9.7   Conformity with Trust Indenture Act. Every supplemental
agreement under this Section 9 executed at a time that the Certificates shall
be subject to the Trust Indenture Act, shall conform to requirements of the
Trust Indenture Act as in effect on the date such supplemental agreement is
executed.

SECTION 10.   AMENDMENTS AND CONSENTS TO COLLATERAL TRUST INDENTURE AND OTHER
              OPERATIVE DOCUMENTS

              (a)      In the event that the Pass Through Trustee, as holder of
any Lessor Note in trust for the benefit of the Certificateholders, receives a
request for a consent to any amendment, modification, waiver or supplement
under the Collateral Trust Indenture or other Operative Document that requires
the consent of the holder of such Lessor Note, the Pass Through Trustee shall
forthwith send a notice of such proposed amendment, modification, waiver or
supplement to each Certificateholder registered on the Register as of such
date. Any such notice shall describe the proposed amendment, modification,
waiver or supplement (or attach a copy thereof). The Pass Through Trustee shall
request from the Certificateholders Directions as to (i) whether or not to
direct the applicable Indenture Trustee to take or refrain from taking any
action which a holder of such Lessor Note has the option to direct, (ii)
whether or not to give or execute any waivers, consents, amendments,
modifications or supplements as a holder of such Lessor Note and (iii) how to
vote any Lessor Note if a vote has been called for with respect thereto. Any
such request shall specify a date by which Certificateholders are requested to
respond. Provided such a request for Certificateholder Direction shall have
been made, in directing any action or casting any vote or giving any consent as
the holder of any Lessor Note, the Pass Through Trustee shall vote or consent
with respect to such Lessor Note in the same proportion as the Certificates
were actually voted by Acts of Holders delivered to the Pass Through Trustee at
least two Business Days before the Pass Through Trustee directs such action or
casts such vote or gives such consent. Notwithstanding the foregoing, but
subject to Section 6.4, in the case that an Event of Default hereunder shall
have occurred and be

                                       44

<PAGE>

continuing, the Pass Through Trustee may, in its own discretion and at its own
direction, consent and notify the applicable Indenture Trustee of such consent
to any amendment, modification, waiver or supplement under the applicable
Collateral Trust Indenture or other Operative Document.

              (b)      With respect to consents, approvals, waivers and
authorizations which under the terms of Section 8 of the applicable Collateral
Trust Indenture may be given by the applicable Indenture Trustee without the
necessity of the consent of any of the holders of Lessor Notes, no consent,
approval, waiver or authorization shall be required hereunder on the part of
the Pass Through Trustee or the Certificateholders.

SECTION 11.   TERMINATION OF PASS THROUGH TRUST

     Section 11.1  Termination of the Pass Through Trust. The respective
obligations and responsibilities of the Facility Lessees and the Pass Through
Trustee created hereby and the Pass Through Trust created hereby shall
terminate upon the distribution to all Certificateholders of all amounts
required to be distributed to them pursuant to this Pass Through Trust
Agreement and the disposition of all property held as part of the Trust
Property; provided, however, that if and to the extent that any of the options,
rights and privileges granted under this Pass Through Trust Agreement, would,
in the absence of the limitation imposed by this sentence, be invalid or
unenforceable as being in violation of the rule against perpetuities or any
other rule or law relating to the vesting of interest in property or the
suspension of the power of alienation of property, then it is agreed that
notwithstanding any other provision of this Pass Through Trust Agreement, such
options, rights and privileges, subject to the respective conditions hereof
governing the exercise of such options, rights and privileges, will be
exercisable only during (a) the longer of (i) a period which will end
twenty-one (21) years after the death of the last survivor of the descendants
living on the date of the execution of this Pass Through Trust Agreement of the
following Presidents of the United States: Franklin D. Roosevelt, Harry S.
Truman, Dwight D. Eisenhower, John F. Kennedy, Lyndon B. Johnson, Richard M.
Nixon, Gerald R. Ford, James E. Carter, Ronald W. Reagan, George H.W. Bush,
William J. Clinton and George W. Bush or (ii) the period provided under the
Uniform Statutory Rule Against Perpetuities or (b) the specific applicable
period of time expressed in this Pass Through Trust Agreement, whichever of (a)
or (b) is shorter.

          Notice of any termination, specifying the Distribution Date (or
Special Distribution Date, as the case may be) upon which the
Certificateholders may surrender their Certificates to the Pass Through Trustee
for payment of the final distribution and cancellation (at maturity, redemption
or otherwise), shall be mailed promptly by the Pass Through Trustee to
Certificateholders not earlier than the 60th day and not later than the 20th
day next preceding such final distribution specifying (A) the Distribution Date
(or Special Distribution Date, as the case may be) upon which final payment of
the Certificates will be made upon presentation and surrender of Certificates
at the office or agency of the Pass Through Trustee therein specified, (B) the
amount of any such final payment, and (C) that the Record Date otherwise
applicable to such Distribution Date (or Special Distribution Date, as the case
may be) is not applicable, payments being made only upon presentation and
surrender of the Certificates at the office or agency of the Pass Through
Trustee therein specified. The Pass Through Trustee shall give such notice to
the Registrar at the time such notice is given to Certificateholders. Upon
presentation

                                       45

<PAGE>

and surrender of the Certificates, the Pass Through Trustee shall cause to be
distributed to Certificateholders amounts distributable on such Distribution
Date or Special Distribution Date, as the case may be, pursuant to Section 4.2
hereof.

          In the event that all of the Certificateholders shall not surrender
their Certificates for cancellation within six months after the date specified
in the above mentioned written notice, the Pass Through Trustee shall give a
second written notice to the remaining Certificateholders to surrender their
Certificates for cancellation and receive the final distribution with respect
thereto. In the event that any money held by the Pass Through Trustee for the
payment of distributions on the Certificates shall remain unclaimed for two
years (or such lesser time as the Pass Through Trustee shall be satisfied,
after sixty days' written notice from the Facility Lessees, is one month prior
to the escheat period provided under applicable law) after the final
distribution date with respect thereto, the Pass Through Trustee shall pay to
each Indenture Trustee the appropriate amount of money relating to such
Indenture Trustee and shall give written notice thereof to the Owner Lessors,
the Owner Participants and the Facility Lessees.

SECTION 12.   MISCELLANEOUS PROVISIONS

     Section 12.1  Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder shall not operate to terminate this Pass
Through Trust Agreement or the Pass Through Trust, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or to
take any action or commence any proceeding in any court for a partition or
winding up of the Pass Through Trust, nor otherwise affect the rights,

right (except as expressly provided herein) to vote or in any manner otherwise
control the operation and management of the Trust Property, the Pass Through

Property and only to the extent that the Pass Through Trustee shall have
received sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of the Agreement. Each Holder of this
Certificate, by its acceptance hereof, agrees that it will look solely to the
income and proceeds from the Trust Property to the extent available for
distribution to such Holder as provided in the Agreement. This Certificate does
not purport to summarize the Agreement and reference is made to the Agreement
for information with respect to the interests, rights, benefits, obligations,
proceeds and duties evidenced hereby. A copy of the Agreement may be examined
during normal business hours at the principal office of the Pass Through
Trustee, and at such other places, if any, designated by the Pass Through
Trustee, by any Certificateholder upon request.

          The Agreement permits, with certain exceptions therein provided,
the amendment thereof and the modification of the rights and obligations of the
Facility Lessees and the rights of the Certificateholders under the Agreement
at any time by the Facility Lessees and the Pass Through Trustee with the
consent of the Holders of Certificates evidencing Fractional Undivided
Interests aggregating not less than a majority in interest of the Fractional
Undivided Interests evidenced by all Certificates at the time Outstanding. Any
such consent by the Holder of this Certificate shall be conclusive and binding
on such Holder and upon all future Holders of this Certificate and of any
Certificate issued upon the transfer hereof or in exchange hereof or in lieu
hereof whether or not notation of such consent is made upon this Certificate.
The Agreement also permits the amendment thereof, in certain limited
circumstances, without the consent of the Holders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Pass Through Trustee in its capacity as
Registrar, or by any successor Registrar, duly endorsed or accompanied by a
written instrument of transfer in form satisfactory to the Pass Through Trustee
and the Registrar duly executed by the Holder hereof or such Holder's attorney
duly authorized in writing, and thereupon one or more new Certificates of
authorized denominations evidencing the same aggregate Fractional Undivided
Interest in the Pass Through Trust will be issued to the designated transferee
or transferees.

          The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of $100,000 Fractional Undivided
Interest and any integral multiples of $1,000 in excess thereof. As provided in
the Agreement and subject to certain limitations therein set forth,
Certificates are exchangeable for new Certificates of authorized denominations

evidencing the same aggregate Fractional Undivided Interest in the Pass Through
Trust, as requested by the Holder surrendering the same.

          No service charge will be made for any such registration of
transfer or exchange, but the Pass Through Trustee shall require payment of an
amount sufficient to cover any tax or charge payable in connection therewith.

          The Pass Through Trustee, the Facility Lessees, the Owner Lessors,
the Registrar and any agent of the Pass Through Trustee or the Registrar may
treat the person in whose name this Certificate is registered as the owner
hereof for all purposes, and neither the Pass Through Trustee, the Facility
Lessees, the Owner Lessors, the Registrar nor any such agent shall be affected
by any notice to the contrary.

          The obligations and responsibilities created by the Agreement and
the Pass Through Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant
to the Agreement and the disposition of all property held as part of the Trust
Property.

     Trustee under the Pass Through Trust Agreement, a signed letter
     containing certain representations and agreements relating to the
     restrictions on transfer of the Certificates (the form of which letter
     can be obtained from the Pass Through Trustee) and an opinion of counsel

     matters as to be capable of evaluating the merits and risks of our
     investment in the Certificates, and we and any accounts for which we are
     acting are each able to bear the economic risk of our or its investment.

          5.      We are acquiring the Certificates purchased by us for our own

     discretion.
