                               QUANTUM CORPORATION

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (unaudited)


1.   Basis of presentation

The accompanying  unaudited condensed  consolidated financial statements reflect
all adjustments,  consisting only of normal recurring  adjustments which, in the
opinion of management,  are necessary for a fair presentation of the results for
the  periods  shown.  The  results  of  operations  for  such  periods  are  not
necessarily indicative of the results expected for the full fiscal year. Certain
prior period amounts have been  reclassified to conform to the current  period's
presentation.  The condensed consolidated balance sheet as of March 31, 1997 has
been derived  from the audited  financial  statements  at that date but does not
include all of the  information  and  footnotes  required by generally  accepted
accounting  principles  for  complete  financial  statements.  The  accompanying
financial  statements  should be read in conjunction with the audited  financial
statements of Quantum Corporation for the fiscal year ended March 31, 1997.


2.   Inventories

   Inventories consisted of the following:

                                          September 28,              March 31,

                                              =========              =========



3.   Net income per share


Net income per share amounts are computed by dividing net income  amounts by the
weighted  average  of  common  and  common  equivalent  shares  (when  dilutive)
outstanding during the period. Primary net income per share computations for the
three and six month periods ended September 28, 1997 and September 29, 1996 were
computed based on weighted  average shares  outstanding,  including the dilutive
impact of common stock equivalents,  which consist of outstanding stock options.
Net income per share  computed  on a fully  diluted  basis for the three and six
month  periods  ended  September  28, 1997 assumes  conversion  of the Company's
outstanding  convertible  subordinated  debentures  as of the  beginning  of the
respective  periods.  Net income per share computed on a fully diluted basis for
the  three  and six  month  periods  ended


                                                                               6
<PAGE>

September  29,  1996 did not  assume  conversion  of the  Company's  outstanding
convertible debt because the effect would have been anti-dilutive.

In February 1997, the Financial  Accounting Standards Board issued Statement No.
128,  "Earnings  per Share,"  which is  required to be adopted in the  Company's
fiscal  quarter  ending  December  28, 1997.  At that time,  the Company will be
required to change the method  currently used to compute  earnings per share and
to restate all prior periods.  Under the new requirements,  primary earnings per
share is replaced by basic earnings per share,  for which the dilutive effect of
stock options will be excluded.  Under  Statement  128, basic earnings per share
will exceed  previously  computed primary earnings per share in periods with net
income. The impact of Statement 128 on the calculation of fully diluted earnings
per share is not expected to be material.

4.   Debt & Capital

The previously outstanding revolving credit line, term loan, and equipment loan,
which had  carrying  amounts of $110  million,  $56  million,  and $14  million,
respectively,  as of March 31,  1997,  were repaid and  terminated  in the first
fiscal 1998 quarter.

In June 1997, the Company entered into an unsecured senior credit facility which
provides a $500 million  revolving  credit line and expires in June 2000. At the
option of the Company,  borrowings under the revolving credit line bear interest
at either LIBOR plus a margin determined by a total funded debt ratio, or a base
rate, with option periods of one to six months.  As of September 28, 1997, there
was no outstanding balance drawn on this line.

The Company  extended until  September 1998 an $85 million  unsecured  Letter of
Credit   facility   with   certain   banks  to  issue   letters   of  credit  to
Matsushita-Kotobuki Electronics and its affiliates.

In July 1997,  the Company  issued $288 million of 7%  convertible  subordinated
notes.  The notes mature on August 1, 2004, and are convertible at the option of
the holder at any time  prior to  maturity,  unless  previously  redeemed,  into
shares of the Company's common stock at a conversion price of $46.325 per share.
The notes are redeemable at the Company's  option on or after August 1, 1999 and
prior to August 1, 2001,  under certain  conditions  related to the price of the
Company's  common stock.  Subsequent to August 1, 2001, the notes are redeemable
at the Company's  option at any time. In the event of certain changes  involving
all or  substantially  all of the Company's common stock, the notes would become
redeemable at the option of the holder. Redemption prices range from 107% of the
principal to 100% at maturity. The notes are unsecured obligations  subordinated
in right of  payment  to all  existing  and future  senior  indebtedness  of the
Company.


5.  Litigation

The Company and certain of its current and former  officers and  directors  have
been named as defendants in two class action  lawsuits,  one filed on August 28,
1996 in the Superior Court of Santa Clara County,  California,  and one filed on
August  30,  1996 in the  U.S.  District  Court  for the  Northern  District  of
California. The plaintiff in both class actions purports to represent a class of
all persons who purchased the Company's  common stock between  February 26, 1996
and June 13,


                                                                               7
<PAGE>


1996.  The  complaints  allege  that the  defendants  violated  various  federal
securities  laws and California  statutes by concealing  and/or  misrepresenting
material adverse  information  about the Company and that individual  defendants
sold shares of the Company's stock based upon material nonpublic information.

On February 25,  1997,  in the Santa Clara County  action,  the Court  sustained
defendants'  demurrer  to most of the  causes of action in the  complaint,  with
leave to amend.  At a June 12, 1997 demurrer  hearing in state court,  the judge
dismissed the action as to four of the individual  defendants with prejudice and
as to three of the individual  defendants without prejudice.  The demurrer as to
the Company was overruled.  Defendants'  motion that the action not be permitted
to proceed as a class  action was denied  without  prejudice  and the hearing on
class certification has been continued for ninety days.

With respect to the federal action,  defendants filed their motion to dismiss on
April 16,  1997.  The  Court  granted  defendants'  motion  to  dismiss  without
prejudice.  On  September  11,  1997,  plaintiff  filed  an  amended  complaint.
Defendants filed a motion to dismiss the complaint on October 24, 1997.

Certain of the Company's  current and former  officers and  directors  were also
named as defendants in a derivative lawsuit, which was filed on November 8, 1996
in the Superior Court of Santa Clara County. The derivative  complaint was based
on  factual  allegations  substantially  similar  to those  alleged in the class
action lawsuits.  Defendants' demurrer to the derivative complaint was sustained
without  prejudice  on  April  14,  1997.  Plaintiffs  did not  file an  amended
complaint. On August 7, 1997, the Court issued an order of dismissal and entered
final judgment dismissing the complaint.


                                                                               8

Quantum is also  involved  in the design,  development,  and  manufacture  of MR
recording  heads used in the Company's  products.  The Company  believes that MR
technology,  which provides higher capacity per disk than conventional thin-film
heads, is replacing  thin-film heads as the leading  recording head  technology.
The Company does not currently  market thin-film or MR heads to other companies.
Effective May 16, 1997, the Company's  involvement  in the design,  development,
and  manufacture  of recording  heads is through a 49%  ownership  interest in a
joint venture with MKE, MKE-Quantum Components LLC (MKQC).

Quantum operates in an industry characterized by rapid technological change. The
Company is currently concentrating its product development efforts on broadening
its existing disk and tape drive product lines through the  introduction  of new
products,  including new tape drives, new high-capacity hard disk drive products
to be manufactured by MKE, as well as new products targeted specifically for the
increasing  storage needs of the desktop  market.  As discussed in the Strategic
Developments  section,  efforts include  developing optical drives based on Near
Field  Recording  TM  technology.  The Company is also  focusing  its efforts on
applying its MR technology to new generations of disk drives.


Strategic Developments

Quantum and TeraStor - Strategic  Cooperation.  In September  1997,  Quantum and
TeraStor  entered into a strategic  agreement  involving Near Field Recording TM
(NFR) disk  drives and  technology.  Under the terms of the  agreement,  Quantum
licensed   TeraStor's   initial   removable  disk  drive  products  and  related
technology.  Quantum and TeraStor will  cooperate in the  development of certain
future products, including the development of a disk drive that is optimized for
use in robotic  libraries.  Each company will manufacture,  market, and sell the
initial products resulting from this agreement. Quantum will also have the right
to  develop,  manufacture,  and  market a variety  of future  products  based on
TeraStor's NFR  technology.  NFR technology is a combination of Solid  Immersion
Lens  (which is an optical  element),  flying head and first  surface  recording
technologies. To date, there are not yet NFR based products in production.


                                                                              12

High-end  Disk Drives - Operating  Considerations.  Quantum is in the process of
considering its alternatives to address the current  operating losses associated
with the Company's high-end disk drive products.  The actions being contemplated
revolve around transition planning for the Company's next generation of high-end
disk  drive  products  in  light of the  changing  competitive  dynamics  in the
high-end marketplace.  Some actions being considered could, if selected,  result
in  non-recurring  charges in the third  fiscal  1998  quarter.  Such  potential
non-recurring charges that may result from future decisions and actions based on
market  conditions  in the  third  fiscal  1998  quarter  could  range  up to an
estimated $35 million, after tax.


Results of Operations

Sales.  Sales for the three and six months ended September 28, 1997, were $1.553
billion and $3.000 billion, respectively,  compared to $1.124 billion and $2.278
billion,  respectively,  for the corresponding periods in fiscal 1997. The sales
increases  reflect an increase in shipments  of DLT TM tape drives,  DLT TM tape
drive-related  products and desk top disk drives,  as well as an increase in the
average price. The increase in the average price reflected a change in the sales
mix to a higher  proportion  of tape drives  which have a higher unit price than
hard disk drive  products,  as well as a desktop hard disk drive sales mix shift
to higher capacity drives which have a higher unit price than the lower capacity
hard  disk  drives  sold  in  the  prior  year  periods.  Although  the  Company
experienced a decline in unit sales and price erosion in the high-end portion of
the  Company's  hard disk drive  product line on a sequential  quarterly  basis,
reflecting  intense  competition,  the sales for this  portion of the  Company's
business  increased on a year-over-year  basis.  This increase reflects a larger
current  customer  base and the impact of the  transition  of the high-end  disk
drive  manufacturing  to MKE during the three and six months ended September 29,
1996.

Sales of desktop  hard drives for the three and six months ended  September  28,
1997,  represented  69% and 68% of total  sales,  respectively,  and the Company
anticipates  that desktop  products  will  continue to  constitute a majority of
sales  in the  future.  Sales  of DLT  TM  product  continued  to  increase  and
represented 22% and 20% of sales in the three and six months ended September 28,
1997, respectively,  compared to 14% and 12%, respectively, in the corresponding
periods in fiscal  1997.  The Company  expects that sales of DLT TM product will
continue to increase as a percentage of the Company's  total sales and operating
profits in the future. For the third quarter of fiscal 1998, the Company expects
sales to follow  seasonal  trends and be higher than the sales level achieved in
the second quarter of fiscal 1998.

Sales to the  Company's  top five  customers  for the three and six months ended
September 28, 1997, represented 39% and 41% of sales, respectively,  compared to
39% and 40% of sales,  respectively,  for the  corresponding  periods  in fiscal
1997. Sales to Compaq Computer,  Inc. were 11% and 10% of sales in the three and
six months ended  September 28, 1997,  respectively,  compared to 12% and 11% of
sales,  respectively,  in the  corresponding  periods of fiscal  1997.  Sales to
Hewlett-Parkard  were 10% and 11% of sales in the  three  and six  months  ended
September  28, 1997,  respectively,  and were less than 10% of sales for both of
the corresponding periods in fiscal 1997.


                                                                              13

Gross Margin Rate.  The gross margin rate  increased  7.1  percentage  points to
19.2% in the quarter ended  September 28, 1997,  from 12.1% in the quarter ended
September  29,  1996.  The gross  margin rate for the first six months of fiscal
1998 was 19.1%,  compared to 12.2% in the  corresponding  period in fiscal 1997.
These margin rate increases reflected a higher proportion of tape drive and tape
drive  related  product  sales in the three and six months ended  September  28,
1997,  compared to the  corresponding  periods in fiscal 1997. This improved the
margin rate as the tape products  achieve a higher gross margin rate compared to
sales of the Company's hard disk drive products.  The gross margin rate increase
also  reflected  an  increase  in  storage  capacity  within  the mix of desktop
products sold in the three and six months ended September 28, 1997,  compared to
the  corresponding  periods in fiscal 1997. This improved the margin rate as the
higher capacity drives earned a higher gross margin rate than the lower capacity
drives.  Although the Company  experienced  margin reduction stemming from sales
erosion in the high-end portion of the Company's hard disk drive product line on
a sequential quarterly basis,  reflecting intense competition,  the gross margin
rate for this portion of the Company's  business  increased on a  year-over-year
basis.  This  increase  reflected  that the gross margin rate earned on high-end
disk  drives had  largely  been  eroded  during  the three and six months  ended
September  29,  1996,  while  the  Company  transitioned   high-end  disk  drive
manufacturing to MKE. The margin rate increases also reflect a minor impact as a
result of the  application  of the equity  method of accounting to the Company's
involvement in the recording heads operations, effective May 16, 1997.


Research and Development  Expenses.  In the three and six months ended September
28, 1997, the Company's research and development  expenses were $74 million,  or
4.8% of sales, and $149 million, or 5.0% of sales, respectively; compared to $70
million, or 6.2% of sales, and $136 million, or 6.0% of sales, respectively,  in
the  corresponding  periods of fiscal  1997.  These  decreases  in research  and
development  expense  as a  percentage  of sales  reflect  the timing of certain
pre-production  activity which varies from quarter to quarter. The decrease also
reflects the impact of applying the equity method of accounting to the Company's
involvement in the recording heads  operations,  effective May 16, 1997. For the
third fiscal 1998 quarter, the Company expects increased expenditures associated
with  pre-production  activity  for  hard  drive  and  tape  drive  products  in
development.  Reflecting  management's  continued  focus on the  development and
timely  introduction  of new  information  storage  products  and  technologies,
research and development expenses for the third fiscal 1998 quarter are expected
to increase over the level achieved in the second fiscal 1998 quarter.


Sales and Marketing Expenses.  Sales and marketing expenses in the three and six
months ended  September 28, 1997,  were $42 million,  or 2.7% of sales,  and $84
million,  or 2.8% of sales,  respectively;  compared to $30 million,  or 2.7% of
sales, and $66 million,  or 2.9% of sales,  respectively,  in the  corresponding
periods in fiscal 1997.  The  increases  in sales and  marketing  expenses  were
related to the costs of supporting the Company's higher volumes of sales.

General and Administrative Expenses.  General and administrative expenses in the
three and six months  ended  September  28, 1997,  were $24 million,  or 1.6% of
sales, and $52 million, or 1.7% of sales, respectively; compared to $17 million,
or 1.5% of  sales,  and $38  million,  or 1.7% of  sales,


                                                                              14
<PAGE>


respectively,  in the  corresponding  periods in fiscal 1997.  The  increases in
general  and  administrative  expenses  reflected  expansion  of  the  Company's
infrastructure.


Interest  and Other  Income/Expense.  Net  interest  income and other income and
expense in the three and six months ended  September  28, 1997 was a net expense
of $17 million and $19  million,  respectively,  compared to $13 million and $25
million,  respectively,  in the corresponding periods in fiscal 1997. The change
in net  expense  reflects  decreases  in  interest  expense  corresponding  to a
decrease in the average amount of debt  outstanding  and an increase in interest
income corresponding to an increase in the average cash balances.  Effective May
16, 1997, the Company's involvement in the recording heads operations is through
its investment in the MKE/Quantum joint venture and this investment is accounted
for  under  the  equity  method.  Prior  to May 16,  1997,  the  recording  head
operations  were fully  consolidated  by Quantum.  Comparing the  year-over-year
second fiscal quarter net expense, the increase reflects a full quarter's impact
of the Company's equity loss related to its investment in the MKE/Quantum  joint
venture.  This equity loss reflects the adverse impact on the MKE/Quantum  joint
venture of sequential  quarterly  sales  erosion in the high-end  portion of the
Company's  hard  disk  drive  product  line for which  the  joint  venture  is a
supplier.


Income  Taxes.  The  effective  tax  rate for the  three  and six  months  ended
September 28, 1997,  at 26% was flat  compared to the rate in the  corresponding
periods ended September 29, 1996.


Liquidity and Capital Resources

At  September  28,  1997,  the  Company  had  $638  million  in  cash  and  cash
equivalents,  compared  to $345  million  at March 31,  1997.  For the six month
period ended  September  28, 1997,  cash was provided by operating and financing
activities.  Operating  activities included cash provided from net income and an
increase  in accounts  payable,  which were  partially  offset by an increase in
inventory and accounts receivable. Financing activities included $288 million of
proceeds from the issuance of 7%  convertible  subordinated  notes in the second
quarter of fiscal 1998.  The  financing  proceeds were  partially  offset by the
repayment of the  outstanding  senior  credit  facility in the first fiscal 1998
quarter. Cash provided by investing activities,  including a $94 million payment
from MKE as part of the formation of the recording heads joint venture  company,
were largely offset by investments in property and equipment and other activity.

In the second fiscal 1998 quarter,  the Company extended until September 1998 an
$85 million  unsecured  Letter of Credit  facility  with certain  banks to issue
letters of credit to Matsushita-Kotobuki Electronics and its affiliates.

The Company has filed a registration  statement  which became  effective on July
24, 1997, pursuant to which the Company may issue debt or equity securities,  in
one or more  series or  issuances,  limited  to $450  million  aggregate  public
offering  price.  Under the  registration  statement,  in July 1997, the Company
issued $288 million of 7% convertible  subordinated  notes.  The notes mature on
August 1,  2004,  and are  convertible  at the  option of the holder at any time
prior to maturity,


                                                                              15
<PAGE>


unless  previously  redeemed,  into shares of the  Company's  common  stock at a
conversion price of $46.325 per share. The notes are redeemable at the Company's
option on or after  August 1, 1999 and prior to August 1,  2001,  under  certain
conditions  related to the price of the Company's  common  stock.  Subsequent to
August 1, 2001, the notes are redeemable at the Company's option at any time. In
the event of certain changes involving all or substantially all of the Company's
common  stock,  the notes would become  redeemable  at the option of the holder.
Redemption  prices range from 107% of the  principal  to 100% at  maturity.  The
notes are unsecured obligations subordinated in right of payment to all existing
and future senior indebtedness of the Company.

The revolving  credit line, term loan, and equipment  loan,  which were paid off
and  terminated  in the first fiscal 1998  quarter had carrying  amounts of $110
million, $56 million, and $14 million, respectively, as of March 31, 1997.

In June 1997, the Company entered into an unsecured senior credit facility which
provides a $500 million  revolving  credit line and expires in June 2000. At the
option of the Company,  borrowings under the revolving credit line bear interest
at either LIBOR plus a margin determined by a total funded debt ratio, or a base
rate, with option periods of one to six months.  As of September 28, 1997, there
was no outstanding balance drawn on this line.

The Company expects to spend  approximately  $185 million for capital equipment,
expansion of the  Company's  facilities,  and leasehold  improvements  in fiscal
1998. These capital  expenditures  will support the tape business,  research and
development, and general corporate operations. Refer to the Future Capital Needs
section of the Trends and  Uncertainties  section for  additional  discussion of
capital.

The  Company  believes  that  its  existing  and  available  capital  resources,
including  its  unsecured  senior credit  facility and any cash  generated  from
operations  will be sufficient to meet all currently  planned  expenditures  and
sustain  operations for the remainder of the fiscal year.  However,  this belief
assumes  that  operating  results  and cash flow from  operations  will meet the
Company's  expectations,  and  actual  results  could vary due to certain of the
factors described in the Trends and Uncertainties section that follows.


Trends and Uncertainties

Operating in the information  storage industry,  Quantum is affected by numerous
trends and  uncertainties,  some of which are  specific  to the  industry  while
others relate more specifically to Quantum. These are discussed below.


                                                                              16

Trends and Uncertainties - Information Storage Industry

Key trends and  uncertainties  inherent in the information  storage industry and
how  these  trends  and  uncertainties   specifically  impact  the  Company  are
summarized below.

       o   Intense  competition - The information  storage products  industry in
           general, and the disk drive market in particular, is characterized by
           intense  competition  that  results  in rapid  price  erosion;  short
           product  life  cycles;  and  continuous  introduction  of  new,  more
           cost-effective  products  offering  increased  levels of capacity and
           performance.

       o   Rapid   technological   change  -  Technology   advancement   in  the
           information storage industry is increasingly rapid.

       o   Customer   concentration   -   High-purchase-volume    customers  for
           information  storage products are concentrated  within a small number
           of computer system manufacturers,  distribution  channels, and system
           integrators.

       o   Fluctuating product demand - The demand for hard disk  drive products
           depends  on the demand  for the  computer  systems in which hard disk
           drives are used, which in turn is affected by computer system product
           cycles and by prevailing economic conditions.

       o   Intellectual  property  conflicts - The hard disk drive  industry has
           been characterized by significant  litigation  relating to patent and
           other intellectual property rights.

Intensely  Competitive  Industry.  To  compete  within the  information  storage
industry,  Quantum  frequently  introduces new products and transitions to newer
versions  of  existing  products.  Product  introductions  and  transitions  are
significant to the operating results of Quantum, and if they are not successful,
the Company would be  materially  and  adversely  affected.  The hard disk drive
market,  in  particular,  also tends to  experience  periods  of excess  product
inventory and intense price competition.  If price competition intensifies,  the
Company may be forced to lower prices more than expected, which could materially
adversely  affect the  Company.  In  addition,  the  Company's  customers  could
commence the  manufacture  of disk and tape drives for their own use or for sale
to others.  Any such loss of customers  could have a material  adverse effect on
the Company.


                                                                              17

Quantum faces direct competition from a number of companies,  including Seagate,
Western Digital, IBM, Maxtor, Exabyte and Sony. In the event that the Company is
unable to compete effectively with these or any other company, the Company would
be materially  adversely  affected.  The Company's  information  storage product
competition can be further broken down as follows:

      Desktop  Storage  Products.  In the market for desktop  products,  Quantum
      competes primarily with Seagate, Western Digital, Maxtor, IBM and Fujitsu.
      Quantum and its competitors  have developed and are developing a number of
      products targeted at particular  segments of this market, such as business
      users and home PC buyers,  and  factors  such as time to market can have a
      significant effect on the success of any particular  product.  The desktop
      market is characterized by more  competitiveness  and shorter product life
      cycles than the information storage industry in general.

      Specialty  Storage  Products.  In the market for tape drives,  the Company
      competes with other  companies that have tape drive product  offerings and
      alternative   formats,   including  Hewlett  Packard,   Exabyte,   Storage
      Technology, and Sony. The Company targets a market segment that requires a
      mission  critical  backup system and competes in this segment based on the
      reliability, data integrity,  performance, capacity and scalability of its
      tape  drives.  Although  the  Company  has  experienced  excellent  market
      acceptance  of its  tape  drive  products,  the  market  may  become  more
      competitive as other companies  broaden their product line in this market.
      As a result, the Company could experience increased price competition.  If
      price  competition  occurs,  the Company may be forced to lower prices, in
      which case the Company could be materially adversely affected.

      Workstation and System Storage Products.  The Company faces competition in
      the  high-capacity  disk drive  market  primarily  from  Seagate,  IBM and
      Fujitsu.  Seagate  has the largest  share of the market for  high-capacity
      disk drives.  Although the same  competitive  factors  identified above as
      being  generally  applicable to the overall disk drive  industry  apply to
      high-capacity  disk drives,  the Company  believes  that the  performance,
      quality and  reliability  of its products  are even more  important to the
      users in this market than to users in the desktop  market.  However,  this
      does not lessen the  intensely  competitive  nature of the high-end of the
      hard disk drive  market.  For example,  in the second fiscal 1998 quarter,
      intense  competition  resulted in  approximately  $20 million of after tax
      operating  losses  associated  with  the  Company's  high-end  disk  drive
      products.  The Company does not  anticipate  that the high-end  disk drive
      products will return to  profitability  prior to shipping next  generation
      products  and there can be no assurance  as to the  profitability  of next
      generation products.  The Company's operating results in the high-capacity
      market  during  the  foreseeable  future is  dependent  on the  successful
      development,   timely   introduction,   market  acceptance,   and  product
      transition  of key new  products,  as to which  there  can be no  positive
      assurance.


                                                                              18

Rapid  Technological  Change, New Product  Development,  and Qualification.  The
combination of an environment of rapid technological changes, short product life
cycles and competitive  pressures  results in gross margins on specific products
decreasing rapidly.  Accordingly, any delay in the introduction of more advanced
and more  cost-effective  products can result in  significantly  lower sales and
gross  margins.  The Company's  future is therefore  dependent on its ability to
anticipate  what  customers  will demand and to develop the new products to meet
this demand.  The Company must also  qualify new  products  with its  customers,
successfully  introduce  these  products  to the market on a timely  basis,  and
commence volume production to meet customer demands.  Due to these factors,  the
Company  expects  that sales of new  products  will  continue  to account  for a
significant  portion of its future sales and that sales of older  products  will
decline accordingly.

The Company is  frequently  in the process of  qualifying  new products with its
customers.   The  customer   qualification  process  for  disk  drive  products,
particularly  high-capacity products, can be lengthy, complex, and difficult. In
addition,  the  Company  transitioned  the  manufacturing  of its high  capacity
products to MKE during the first half of fiscal 1997, and MKE has been in volume
production of high-end  products since the completion of the transition.  In the
event that the Company is unable to obtain  additional  customer  qualifications
for new  products  in a timely  manner,  or at all,  or in the event that MKE is
unable to continue to  manufacture  such products in volume and with  consistent
high quality, the Company would be materially adversely affected.

There can be no assurance that the Company will be successful in the development
and marketing of any new products and  components  in response to  technological
change or evolving  industry  standards,  that the Company  will not  experience
difficulties   that  could   delay  or  prevent  the   successful   development,
introduction  and  marketing  of  these  products  and  components;  or that the
Company's new products and components will  adequately meet the  requirements of
the  marketplace  and achieve  market  acceptance.  In  addition,  technological
advances in magnetic,  optical or other technologies,  or the development of new
technologies,  could result in the  introduction  of  competitive  products with
superior  performance  to and  substantially  lower  prices  than the  Company's
products.  Further,  the  Company's new products and  components  are subject to
significant  technological  risks.  If the  Company  experiences  delays  in the
commencement of commercial shipments of new products or components,  the Company
could experience delays or loss of product sales. If the Company is unable,  for
technological  or other  reasons,  to develop and  introduce  new  products in a
timely   manner  in  response  to  changing   market   conditions   or  customer
requirements, the Company would be materially adversely affected.

As part of the Company's  strategy to remain  technologically  competitive,  the
Company  has  invested  in  technologies,  such as in NFR  through  a  strategic
alliance  with and  investment in TeraStor,  and its  investment in MR recording
heads  through  the joint  venture,  MKQC.  There can be no  assurance  that the
technologies,  companies  and ventures in which the Company has invested will be
be profitable in the information  storage  industry.  Adverse  technological  or
operating  outcomes  could  result in  impairment  and write down of  associated
investments which could have a material adverse impact on the Company.


                                                                              19
<PAGE>


Customer Concentration.  In addition to the information storage industry and the
Company's  customer base being  concentrated,  the  customers  generally are not
obligated  to purchase any minimum  volume of the  Company's  products,  and the
Company's  relationships with its customers are generally  terminable at will by
its customers.

Sales of the Company's  desktop and tape  products,  which  together  comprise a
majority of its overall sales,  were  concentrated with several key customers in
the six months ended  September  28,  1997,  and the fiscal year ended March 31,
1997.  Sales  to the  Company's  top five  customers  for the six  months  ended
September 28, 1997,  represented  41% of sales,  and 38% of sales for the fiscal
year ended March 31, 1997.  In the six month period  ended  September  28, 1997,
revenue  from  the  top  five  customers  was  derived  from  both  the  OEM and
Distribution sales channel, 30% and 11% respectively.  Two OEMs, Hewlett Packard
and Compaq represented 11% and 10%,  respectively,  of total revenue.  No single
distribution channal customer represented 10% or more of total revenue.  Because
of the rapid and  unpredictable  changes in market  conditions,  the  Company is
unable to predict whether or not there will be any significant  change in demand
for any of its  customers'  products in the  future.  In the event that any such
changes result in decreased demand for the Company's  products,  whether by loss
of or delays in orders, the Company could be materially adversely affected.

Fluctuation in Product Demand.  Fluctuation in demand for the Company's products
generally results in fluctuations in the Company's operating results. Demand for
computer  systems-especially in the PC market segment, where the Company derives
a significant  amount of its disk drive sales has  historically  been subject to
significant fluctuations. Such fluctuations in end-user demand have in the past,
and may in the future,  result in the deferral or cancellation of orders for the
Company's  products,  each of which could have a material  adverse effect on the
Company. During the past several years, there has been significant growth in the
demand for PCs, a portion of which represented sales of PCs for use in the home.
However,  many analysts predict that future growth may be at a moderately slower
rate than the rate experienced in recent years.

Sales of tape  drives and tape  drive-related  products  have  tended to be more
stable  and have  become a  significant  component  of  sales  for the  Company.
Beginning in the second quarter of fiscal 1998,  sales of DLT TM tape drives and
DLT TM tape  drive-related  products  achieved  gross  margin and  profitability
roughly  comparable to that achieved from the sale of the Company's desktop hard
drive  products.  In this regard the company  expects  sales of DLT TM products,
which represented 20% of sales and a much higher percentage of operating profits
for the six months  ended  September  28, 1997,  will  continue to increase as a
percentage of the Company's total sales and operating  profits in the future. On
a sequential  quarterly  basis in Fiscal 1998,  the Company  expects the rate of
sales growth to lessen  significantly as compared to the rates achieved over the
past year. However,  there can be no assurance that any growth expectations will
be achieved or that current market conditions will continue.

The Company has  experienced  longer product cycles for its tape drives and tape
drive-related  products,  compared with the short  product  cycles of disk drive
products. However, there is no assurance that this trend will continue.


                                                                              20
<PAGE>


The Company could experience  decreases in demand for any of its products in the
future, which could have a material adverse effect on the Company. For the third
fiscal 1998 quarter,  the Company  expects to experience  continued gross margin
pressure with respect to its high-end hard disk drive products.

The hard disk  drive  industry  has also  been  subject,  from time to time,  to
seasonal   fluctuations  in  demand.  The  Company  has  typically   experienced
increasing  demand in the quarter  ending  December 31 compared with the quarter
ending  September 30. The Company expects this trend to continue with respect to
the quarter ended December 28, 1997. In addition,  the Company's  shipments tend
to be highest in the third month of each quarter,  which occurred in the quarter
ended  September  28, 1997 and which the  Company  expects to occur again in the
quarter  ending  December 28, 1997. As a result,  and because the Company has no
long-term purchase commitments from its customers, future demand is difficult to
predict.  The failure by the Company to complete shipments in the final month of
a quarter due to a decline in customer demand,  manufacturing  problems or other
factors would adversely affect the Company's operating results for that quarter.


Intellectual  Property Matters.  From time to time, the Company is approached by
companies and individuals  alleging  Quantum's need for a license under patented
technology that Quantum assertedly uses. If required,  there can be no assurance
that  licenses  to  any  such  technology  could  be  obtained  or  obtained  on
commercially  reasonable terms. Adverse resolution of any intellectual  property
litigation  could subject the Company to substantial  liabilities and require it
to refrain  from  manufacturing  certain  products.  In  addition,  the costs of
engaging in such litigation may be substantial, regardless of the outcome.


Trends and Uncertainties More Specific to Quantum

Certain trends and uncertainties relate more specifically to Quantum and are not
necessarily  indicative of the information  storage  industry as a whole.  These
trends and  uncertainties  include  dependence on MKE for the manufacture of the
disk drives that  Quantum  develops and markets,  costs  associated  with the MR
recording head  development and  manufacture,  the recording heads joint venture
with MKE, dependence on suppliers,  component  shortages,  future capital needs,
warranty costs,  foreign  manufacturing,  and price volatility of Quantum common
stock.  For  information  regarding  litigation  refer to Note 5 of the Notes to
Condensed Consolidated Financial Statements.

Dependence on MKE Relationship.  Quantum is dependent on MKE for the manufacture
of its disk drive products.  Approximately 80% of the Company's sales in the six
months  ended  September  28,  1997,  and 81% of the sales in year  ended  March
31,1997,  were  derived from  products  manufactured  by MKE. In  addition,  the
formation of the joint venture with MKE to produce  recording heads used in disk
drive production in combination with the transition of the  manufacturing of the
Company's  high-capacity  products  to MKE in  fiscal  1997 has  resulted  in an
increased  dependence on MKE. The Company's  relationship  with MKE is therefore
critical to the Company's business and financial performance.


                                                                              21
<PAGE>


In May 1997,  Quantum completed  renegotiation of its master agreement with MKE,
which covers the general terms of the business  relationship.  The agreement was
extended  for a period  of 10  years,  unless  terminated  sooner as a result of
certain specified events including a change-in-control of either Quantum or MKE.
MKE currently manufactures all of the hard disk drives developed and marketed by
Quantum.  Quantum's  relationship  with MKE,  which dates from 1984, is built on
Quantum's  engineering and design expertise and MKE's high-volume,  high-quality
manufacturing expertise.


The Company's  dependence on MKE entails,  among others, the following principal
risks:

      Quality and  Delivery.  The Company  relies on MKE's  ability to bring new
      products  rapidly to volume  production at low cost, to meet the Company's
      stringent quality requirements, and to respond quickly to changing product
      delivery  schedules from the Company.  This requires,  among other things,
      close and  continuous  collaboration  between  the  Company and MKE in all
      phases of design, engineering,  and production. The Company's business and
      financial results would be adversely affected if products  manufactured by
      MKE fail to satisfy the Company's quality requirements or if MKE is unable
      to meet the Company's delivery commitments.  In the event MKE is unable to
      satisfy Quantum's production  requirements,  the Company would not have an
      alternative  manufacturing  source to meet the demand without  substantial
      delay and disruption of the Company's operations. As a result, the Company
      would be materially adversely affected.

      Volume and Pricing.  MKE's  production  schedule is based on the Company's
      forecasts  of its  product  purchase  requirements,  and the  Company  has
      limited  contractual rights to modify short-term purchase orders issued to
      MKE. Further,  the demand in the desktop business is inherently  volatile,
      and there is no assurance  that the Company's  forecasts are accurate.  In
      addition,  the Company  periodically  negotiates pricing arrangements with
      MKE. The failure of the Company to accurately forecast its requirements or
      successfully  adjust  MKE's  production  schedule,  which  could  lead  to
      inventory  shortages  or  surpluses,  or  the  failure  to  reach  pricing
      agreements  reasonable to the Company would have a material adverse effect
      on the Company.

      Manufacturing  Capacity and Capital Commitment.  The Company believes that
      MKE's current and committed  manufacturing  capacity should be adequate to
      meet the Company's  requirements  at least through the end of fiscal 1998.
      The Company's  future growth will require,  however,  that MKE continue to
      devote substantial  financial  resources to property,  plant and equipment
      and working capital to support manufacture of the Company's  products,  as
      to which  there can be no  assurance.  In the event  that MKE is unable or
      unwilling to meet the Company's manufacturing  requirements,  there can be
      no assurance that the Company would be able to obtain an alternate  source
      of supply.  Any such failure to obtain an alternative  source would have a
      material adverse effect on the Company.


                                                                              22

MR  Recording  Heads  Development  and  Manufacturing.  Since  the  fiscal  1995
acquisition  of MR recording  heads  technology  as part of the  acquisition  of
certain   businesses  of  the  Storage   Business  Unit  of  Digital   Equipment
Corporation,  Quantum has made significant efforts to advance the development of
its MR recording  heads  capability.  To further  this  effort,  MKE and Quantum
formed a joint  venture,  MKQC in the first quarter of fiscal 1998 to partner in
the research,  development, and production of MR heads and technology.  However,
MR  technology  is  relatively  complex  and,  to date,  the  Company and MKQC's
manufacturing  yields for its MR heads  have been lower than would be  necessary
for cost effective production of MR recording heads. The Company does not expect
cost-effective production of MR recording heads to be realized in the near term.
Until that time,  the Company will incur losses based on its pro rata  ownership
interest in the new joint venture.  However,  there can be no assurance that the
anticipated  benefits of the joint venture will be realized on a timely basis or
at all.  The Company  currently  obtains 80% to 85% of its MR heads from outside
sources.

Dependence on Suppliers of Components and Sub-Assemblies;  Component  Shortages.
Each of the  Company  and its  manufacturing  partner,  MKE,  are  dependent  on
qualified  suppliers for  components  and  sub-assemblies,  including  recording
heads, media, and integrated circuits, which are essential to the manufacture of
the Company's  disk drive and tape drive  products.  In connection  with certain
products,  the  Company  and  MKE  qualify  only a  single  source  for  certain
components  and  sub-assemblies,  which  can  magnify  the  risk  of  shortages.
Component shortages have constrained the Company's sales growth in the past, and
the Company believes that the industry will  periodically  experience  component
shortages.  For  example,  during the quarter  ended  September  28,  1997,  the
Company's  ability  to meet  customer  demand for its tape  drive  products  was
somewhat constrained by component  availability and manufacturing  capacity.  If
component  shortages occur, or if the Company  experiences quality problems with
component  suppliers,  shipments of products could be  significantly  delayed or
costs significantly increased, which would have a material adverse effect on the
Company.

Future Capital Needs.  The information  storage industry is capital and research
and  development  intensive  and the  Company  will  need to  maintain  adequate
financial resources for capital expenditures,  working capital, and research and
development, in order to remain competitive in the information storage business.
The Company believes that it will be able to fund these capital  requirements at
least  through  fiscal  1998.  However,  if the Company  decides to increase its
capital  expenditures  further,  or sooner than  presently  contemplated,  or if
results of operations do


                                                                              23
<PAGE>


not meet the Company's  expectations,  the Company could require additional debt
or equity  financing.  There can be no assurance that such additional funds will
be available to the Company or will be available on favorable terms. The Company
may  also  require   additional   capital  for  other   purposes  not  presently
contemplated. If the Company is unable to obtain sufficient capital, it could be
required  to  curtail  its  capital   equipment  and  research  and  development
expenditures, which could adversely affect the Company.

Warranty.  Quantum generally  warrants its products against defects for a period
of one to five  years.  A  provision  for  estimated  future  costs  relating to
warranty  expense is recorded  when  products are shipped.  The actual  warranty
expenditures  could have a  material  unfavorable  impact on the  Company if the
actual  rate of unit  failure or the cost to repair a unit is greater  than what
the Company has used in estimating the warranty expense accrual.

Risks Associated with Foreign Manufacturing.  Many of the Company's products are
currently  manufactured  outside the United States. As a result,  the Company is
subject to certain risks associated with contracting with foreign manufacturers,
including obtaining requisite United States and foreign governmental permits and
approvals,  currency exchange  fluctuations,  currency  restrictions,  political
instability,  labor  problems,  trade  restrictions,  and  changes in tariff and
freight rates.

Foreign Exchange  Contracts.  The Company manages the impact of foreign currency
exchange rate changes on certain foreign currency receivables and payables using
foreign  currency  forward  exchange  contracts.  With this approach the Company
expects  to  minimize  the  impact of  changing  foreign  exchange  rates on the
Company's  net  income.  However,  there can be no  assurance  that all  foreign
currency  exposures  will be  adequately  managed,  and the Company  could incur
material charges as a result of changing foreign exchange rates.

Volatility of Stock Price.  The market price of the  Company's  common stock has
been, and may continue to be,  extremely  volatile.  Factors such as new product
announcements by the Company or its competitors;  quarterly  fluctuations in the
operating  results  of  the  Company,  its  competitors,  and  other  technology
companies;  and general conditions in the computer market may have a significant
impact on the market price of the common stock.  In  particular,  if the Company
were to  report  operating  results  that did not meet the  expectations  of the
analysts,  the market  price of the common stock could be  materially  adversely
affected.


                                                                              24

Payment Date, on the date required under Section  22.1(i) in connection with the
Lessee's exercise of the Remarketing  Option and on any date on which this Lease
shall terminate.

         (b) Basic Rent  shall be due and  payable  (i) during the  Construction
Period, in the manner set forth in Section 3.8(d) of the Participation Agreement
and (ii)  thereafter,  in lawful money of the United States and shall be paid by
wire transfer of  immediately  available  funds on the due date therefor to such
account  or  accounts  at such  bank or banks or to the  Agent or in such  other
manner as the Agent shall from time to time direct.

         (c) Neither the Lessee's inability or failure to take possession of all
or any portion of the Property  when  delivered by the Lessor,  nor the Lessor's
inability or failure to deliver all or any portion of the Property to the Lessee
on or before the Land Interest  Acquisition Date or the applicable Funding Date,
whether or not  attributable  to any act or omission of the Lessee or any act or
omission  of the  Lessor,  or for any other  reason  whatsoever,  shall delay or
otherwise  affect the Lessee's  obligation to pay Rent for the Property from and
after commencement of the Term.

         3.2.  Payment of Basic Rent. Basic Rent shall be paid absolutely net to
the  Lessor,  so that this  Lease  shall  yield to the  Lessor  the full  amount
thereof,  without  setoff,  deduction or reduction,  whether or not the Lessee's
quiet  possession  of the Property is disturbed,  except as otherwise  expressed
herein and in Section 13.5(e) of the Participation Agreement.

         3.3.  Supplemental  Rent.  The  Lessee  shall pay to the  Lessor or the
Person entitled thereto any and all Supplemental Rent promptly as the same shall
become due and payable,  and if the Lessee fails to pay any  Supplemental  Rent,
the Lessor shall have all rights,  powers and remedies provided for herein or by
law or equity or otherwise in the case of nonpayment  of Basic Rent.  The Lessee
shall pay to the Lessor, as Supplemental Rent, among other things, on demand, to
the extent permitted by Applicable Law, interest at the applicable  Overdue Rate
on any  installment of Basic Rent not paid when due for the period for which the
same shall be overdue and on any payment of Supplemental  Rent not paid when due
or  demanded  by the Lessor for the period  from the due date or the date of any
such demand, as the case may be, until the same shall be paid. The expiration or
other termination of the Lessee's  obligations to pay Basic Rent hereunder shall
not limit or modify the  obligations of the Lessee with respect to  Supplemental
Rent.  Unless  expressly  provided  otherwise in this Lease, in the event of any
failure on the part of the Lessee to pay and discharge any Supplemental  Rent as
and when due,  the  Lessee  shall  also  promptly  pay and  discharge  any fine,
penalty,  interest or cost which may be  assessed  or added under any  agreement
with a third party for nonpayment or late payment of such Supplemental Rent, all
of which shall also constitute Supplemental Rent.

         3.4.  Method of  Payment.  Each  payment  of Rent  shall be made by the
Lessee to the Agent by 12:00 noon, San Francisco time at the place of payment in
funds  consisting of lawful currency of the United States of America which shall
be  immediately  available on the scheduled date when such payment shall be due,
unless  such  scheduled  date  shall not be a Business  Day,  


                                       -4-

<PAGE>


in which case such payment shall be made on the next succeeding  Business Day or
as otherwise  required by the definition of the term "Interest Period" set forth
in Appendix 1 hereto.  Payments  initiated  after 12:00 noon, San Francisco time
shall be deemed received on the next succeeding Business Day.



                                   ARTICLE IV

         4.1.  Utility  Charges.  The  Lessee  shall pay or cause to be paid all
charges for  electricity,  power,  gas, oil,  water,  telephone,  sanitary sewer
service and all other rents and utilities used in or on the Property  during the
Term.  The Lessee shall be entitled to receive any credit or refund with respect
to any utility  charge paid by the Lessee and the amount of any credit or refund
received by the Lessor on account of any utility charges paid by the Lessee, net
of the costs and expenses  reasonably  incurred by the Lessor in obtaining  such
credit or refund,  shall be promptly  paid over to the  Lessee.  All charges for
utilities imposed with respect to the Property for a billing period during which
this Lease expires or terminates shall be adjusted and prorated on a daily basis
between the Lessor and the Lessee,  and each party  shall pay or  reimburse  the
other for each party's pro rata share thereof, except that if the Lessee retains
possession of the Property  after  termination  or expiration of this Lease,  no
such adjustment and proration shall be made.


                                    ARTICLE V

         5.1. Quiet Enjoyment.  Subject to the rights of the Lessor contained in
Section  17.2  and the  other  terms  of this  Lease  and so long as no Event of
Default shall have occurred and be  continuing,  the Lessee shall  peaceably and
quietly  have,  hold and enjoy the property  for the Term,  free of any claim or
other action by the Lessor or anyone  rightfully  claiming by,  through or under
the Lessor (other than the Lessee) with respect to any matters  arising from and
after the first day of the Lease Term.


                                   ARTICLE VI

         6.1.  Net Lease.  This Lease shall  constitute  a net lease.  It is the
further  express intent of Lessor and Lessee that the  obligations of Lessor and
Lessee hereunder shall be separate and independent  covenants and agreements and
that the  Basic  Rent and  Supplemental  Rent,  and all other  charges  and sums
payable by Lessee  hereunder,  shall commence at the times  provided  herein and
shall  continue to be payable in all events  unless the  obligations  to pay the
same shall be  terminated  pursuant to an express  provision in this Lease.  Any
present  or future law to the  contrary  notwithstanding,  this Lease  shall not
terminate,  nor  shall the  Lessee be  entitled  to any  abatement,  suspension,
deferment, reduction, setoff, counterclaim, or defense with respect to the Rent,
nor shall the  obligations  of the  Lessee  hereunder  be  affected  (except  as
expressly  herein  permitted and by performance of the obligations in connection
therewith)  by reason  of:  (i) any  defect in the  condition,  merchantability,
design,  construction,  quality or fitness  for use of the  Property or any part
thereof,  or the failure of the Property to comply with all Requirements of Law,
including  any  inability  to  occupy  or use the  Property  by  reason  of such
non-compliance;  (ii)  any  damage  to,  removal,  abandonment,  salvage,  loss,
contamination of or Release from, scrapping or destruction of or any requisition
or taking of the Property or any part thereof; (iii) any restriction, prevention
or  curtailment  of or  interference  with any use of the  




                                       -5-

<PAGE>



Property or any part thereof including eviction;  (iv) any defect in title to or
rights to the  Property  or any Lien on such title or rights or on the  Property
(other than Lessor  Liens);  (v) any change,  waiver,  extension,  indulgence or
other action or omission or breach in respect of any  obligation or liability of
or by the Lessor, the Agent or any Participant; (vi) any bankruptcy, insolvency,
reorganization,  composition, adjustment, dissolution, liquidation or other like
proceedings  relating to the Lessee, the Lessor, the Agent, any Participant,  or
any other Person,  or any action taken with respect to this Lease by any trustee
or receiver of the Lessee,  the Lessor,  the Agent, any Participant or any other
Person, or by any court, in any such proceeding; (vii) any claim that the Lessee
has or might have against any Person,  including without  limitation the Lessor,
any vendor,  manufacturer,  contractor of or for the Property,  the Agent or any
Participant;  (viii) any  failure on the part of the Lessor to perform or comply
with any of the terms of this Lease,  any other Operative  Document or any other
agreement;   (ix)  any   invalidity   or   unenforceability   or  illegality  or
disaffirmance  of this Lease or against or by the Lessee or any provision hereof
or any of the other Operative Documents or any provision of any thereof; (x) the
impossibility  or illegality of performance  by the Lessee,  the Lessor or both;
(xi) any  action  by any  court,  administrative  agency  or other  Governmental
Authority;  (xii) any restriction,  prevention or curtailment of or interference
with the  construction  on or any use of the  Property or any part  thereof;  or
(xiii) any other cause or  circumstances  whether  similar or  dissimilar to the
foregoing and whether or not the Lessee shall have notice or knowledge of any of
the foregoing.  The parties intend that the obligations of the Lessee  hereunder
shall be covenants and  agreements  that are separate and  independent  from any
obligations of the Lessor  hereunder or under any other Operative  Documents and
the obligations of the Lessee shall continue  unaffected unless such obligations
shall have been modified or terminated in accordance  with an express  provision
of this Lease.

         6.2. No  Termination  or Abatement.  The Lessee shall remain  obligated
under this Lease in  accordance  with its terms and shall not take any action to
terminate,   rescind  or  avoid  this  Lease,  notwithstanding  any  action  for
bankruptcy,  insolvency,  reorganization,  liquidation,  dissolution,  or  other
proceeding  affecting the Lessor,  the Agent or any  Participant,  or any action
with respect to this Lease or any Operative  Document  which may be taken by any
trustee,  receiver or liquidator of the Lessor,  the Agent or any Participant or
by any court  with  respect to the  Lessor,  the Agent or any  Participant.  The
Lessee hereby waives all right (i) to terminate or surrender  this Lease (except
as provided  herein) or (ii) except as  otherwise  provided in this Lease or the
Participation Agreement with regard to withholding taxes, to avail itself of any
abatement,  suspension,  deferment,  reduction,  setoff, counterclaim or defense
(other than the defense of payment)  with respect to any Rent.  The Lessee shall
remain  obligated  under this Lease in accordance  with its terms and the Lessee
hereby  waives  any and all  rights  now or  hereafter  conferred  by statute or
otherwise to modify or to avoid strict  compliance  with its  obligations  under
this Lease.  Notwithstanding any such statute or otherwise,  the Lessee shall be
bound by all of the terms and conditions contained in this Lease.

                                   ARTICLE VII

         7.1.  Ownership  of the  Property.  (a) It is the intent of the parties
hereto  that:  (i) this Lease  constitutes  an  "operating  lease"  pursuant  to
Statement of Financial  Accounting Standards No. 13, as amended, for purposes of
Lessee's financial reporting, and (ii) for purposes of federal, state, and local
income  or  franchise  taxes and for any other tax  imposed  on or  measured  by
income,  the  transaction  contemplated  hereby is a financing  arrangement  and
preserves ownership in the Property in the Lessee. Nevertheless,  the Lessee and
the Lessor  acknowledge and agree that none of the Lessee, the Agent, the Lessor
nor any  Participant  has made any  representations  or warranties to the Lessee
concerning  the  tax,  accounting  or  legal  characteristics  of the  Operative
Documents and that they have obtained and relied upon such tax,  accounting  and
legal  advice  concerning  the  Operative  Documents  as they deem  appropriate.
Accordingly,  and  notwithstanding  any provision of this Lease to the contrary,
the  Lessor  and the  Lessee  agree  and  declare  that:  (i)  the  transactions
contemplated hereby are intended to have a dual, rather than a single, form; and
(ii) all  references in this Lease to the "lease" of the Property  which fail to
reference  such  dual  form do so as a  matter  of  convenience  only and do not
reflect  the  intent of the  Lessor  and the  Lessee as to the true form of such
arrangements.

         (b)   Anything   to   the   contrary   in   the   Operative   Documents
notwithstanding, the Lessor and the Lessee intend and agree that with respect to
the nature of the  transactions  evidenced  by this Lease in the  context of the
exercise  of  remedies  under  the  Operative  Documents,   including,   without
limitation,  in the case of any  insolvency  or  receivership  proceedings  or a
petition  under  the  United  States  bankruptcy  laws or any  other  applicable
insolvency  laws or  statute  of the  United  States of  America or any State or
Commonwealth thereof affecting the Lessee, the Lessor, or any Participant or any
enforcement or collection actions, (i) the transactions  evidenced by this Lease
are loans made by the Lessor  and the  Participants  as  unrelated  third  party
lenders  to the Lessee  secured by the  Property,  (ii) the  obligations  of the
Lessee  under  this  Lease  to pay  Basic  Rent and  Supplemental  Rent or Asset
Termination Value in connection with a purchase of the Property pursuant to this
Lease  shall  be  treated  as  payments  of  interest  on  and   principal   of,
respectively,  loans from the Lessor and the  Participants  to the  Lessee,  and
(iii) this Lease  grants a security  interest  and  mortgage or deed of trust or
lien,  as the case may be, in the Property and the  collateral  described in the
Mortgage to the Lessor,  the Agent and the  Participants  to secure the Lessee's
performance  under and  payment  of all  amounts  under this Lease and the other
Operative Documents.

         (c) Specifically,  without limiting the generality of subsection (b) of
this Section 7.1, the Lessor and the Lessee  further  intend and agree that, for
the  purpose of securing  the  Lessee's  obligations  for the  repayment  of the
above-described  loans from the Lessor and the  Participants to the Lessee,  (i)
this  Lease  shall  also be  deemed to be a  security  agreement  and  financing
statement  within the meaning of Article 9 of the Uniform  Commercial  Code (and
specifically,  a  construction  mortgage,  as said term is  defined  in  Section
9-313(1)(c) of the Uniform Commercial Code) and a real property mortgage or deed
of trust; (ii) the conveyance provided for in Article II shall be deemed to be a
grant by the Lessee to the Lessor,  the Agent and the Participants of a mortgage
lien and security  interest in all of the Lessee's right,  title and interest



                                       -7-

<PAGE>

in and to the  Property  and the  collateral  described  in the Mortgage and all
proceeds of the  conversion,  voluntary or  involuntary,  of the foregoing  into
cash,  investments,  securities or other property,  whether in the form of cash,
investments,  securities or other property (it being  understood that the Lessee
hereby mortgages and warrants and grants a security interest in the Property and
the  collateral  described  in the  Mortgage  to the  Lessor,  the Agent and the
Participants to secure such loans); (iii) the possession by the Lessor or any of
its agents of notes and such other items of property as constitute  instruments,
money,  negotiable  documents or chattel paper shall be deemed to be "possession
by the secured party" for purposes of perfecting the security  interest pursuant
to  Section  9-305  of the  Uniform  Commercial  Code;  and  (iv)  all  Accounts
established  with  Defeasance  Deposit  Depositary  Bank  pursuant  to the  Cash
Collateral  Agreement shall be "Security Accounts" within the meaning of Section
8501 of the UCC, all Collateral from time to time on deposit in any such Account
shall be  deemed  to be a  "Financial  Asset"  within  the  meaning  of  Section
8102(a)(9) of the UCC, and the execution and delivery by Lessee and Agent of the
Notice  of  Security  Interest  attached  to the Cash  Collateral  Agreement  as
Attachment  No. 2 and the  execution  and  delivery of the  Acknowledgement  and
Agreement of Depositary  Bank attached to the Notice of Security  Interest shall
be deemed to grant to Agent  "control" of the  Collateral  within the meaning of
Section 8106 of the UCC for the purpose of  perfecting a security  interest in a
Financial Asset pursuant to Section 9115(1)(e) of the UCC; provided however,  if
any Account is determined to be a deposit  account within the meaning of Section
9302(1)(g) of the UCC, the Notice of Security Interest delivered pursuant to the
Cash  Collateral  Agreement  constitutes  notice for the purpose of perfecting a
security interest in a deposit account pursuant to that Section.  The Lessor and
the Lessee shall, to the extent  consistent  with this Lease,  take such actions
and  execute,   deliver,  file  and  record  such  other  documents,   financing
statements,  mortgages and deeds of trust as may be necessary to ensure that, if
this  Lease  were  deemed to  create a  security  interest  in the  Property  in
accordance  with this Section,  such security  interest  would be deemed to be a
perfected  security  interest of first priority under Applicable Law and will be
maintained as such throughout the Term.

         (d) Specifically, without limiting the generality of anything contained
in this Section 7.1,  the Lessor and the Lessee  further  intend and agree that,
for  purposes  of filing  federal,  state and local  returns,  reports and other
statements  relating to income or franchise  taxes,  or any other taxes  imposed
upon or  measured  by  income,  (i) the  Lessee  shall be  entitled  to take any
deduction,  credit,  allowance or other reporting  position  consistent with its
status  as  owner  of  the  Property;  and  (ii)  neither  the  Lessor  nor  the
Participants shall take a position on their respective federal,  state and local
returns, reports and other statements relating to income or franchise taxes that
is inconsistent with the Lessee's status as owner of the Property, provided that
the Lessor and any Participant may take a position that is inconsistent with the
Lessee's  status as owner of the Property if: (x) there has been a change in law
or  regulation  so requiring  as  supported by an opinion of counsel  reasonably
acceptable  to the Lessee  that there is not  substantial  authority  for such a
consistent  reporting  position;  or (y) (A) there has been an administrative or
judicial  holding  that the Lessee is not the owner of the Property for such tax
purposes,  (B) the Lessee  has no right to  contest  such  holding  pursuant  to
Section 13.5 of the Participation  Agreement, and (C) the Lessee's lack of right
to  contest  is not  the  result  of an  Indemnitee's  waiver  of its  right  to
indemnification  pursuant to Section 13.5(f)(iii) of the Participation Agreement
or  failure of 


                                       -8-

<PAGE>

the  amount  at issue  to  exceed  the  minimum  amount  set  forth  in  Section
13.5(f)(iv)(B) of the Participation Agreement.

         8.1. Condition of the Property. THE LESSEE ACKNOWLEDGES AND AGREES THAT

LESSEE FURTHER  ACKNOWLEDGES  AND AGREES THAT IT IS LEASING THE PROPERTY "AS IS"
WITHOUT REPRESENTATION, WARRANTY OR COVENANT (EXPRESS OR IMPLIED) BY THE LESSOR,
THE AGENT OR ANY  PARTICIPANT AND IN EACH CASE SUBJECT TO (A) THE EXISTING STATE
OF TITLE, (B) THE RIGHTS OF ANY PARTIES IN POSSESSION THEREOF,  (C) ANY STATE OF
FACTS  WHICH AN  ACCURATE  SURVEY OR PHYSICAL  INSPECTION  MIGHT  SHOW,  AND (D)
VIOLATIONS OF  REQUIREMENTS  OF LAW WHICH MAY EXIST ON THE DATE HEREOF.  NEITHER
THE LESSOR,  THE AGENT NOR ANY  PARTICIPANT  HAS MADE OR SHALL BE DEEMED TO HAVE
MADE ANY  REPRESENTATION,  WARRANTY OR COVENANT (EXPRESS OR IMPLIED) OR SHALL BE
DEEMED  TO HAVE ANY  LIABILITY  WHATSOEVER  AS TO THE TITLE  (INCLUDING  BUT NOT
LIMITED TO ANY IMPLIED  LIABILITY  RELATING  TO A COVENANT  OF QUIET  ENJOYMENT,
WHICH THE LESSEE HEREBY EXPRESSLY WAIVES), VALUE, HABITABILITY,  USE, CONDITION,
DESIGN,  OPERATION, OR FITNESS FOR USE OF THE PROPERTY (OR ANY PART THEREOF), OR
ANY OTHER REPRESENTATION,  WARRANTY OR COVENANT WHATSOEVER,  EXPRESS OR IMPLIED,
WITH RESPECT TO THE PROPERTY (OR ANY PART  THEREOF) AND NEITHER THE LESSOR,  THE
AGENT NOR ANY  PARTICIPANT  SHALL BE LIABLE FOR ANY  LATENT,  HIDDEN,  OR PATENT
DEFECT  THEREIN OR THE FAILURE OF THE PROPERTY,  OR ANY PART THEREOF,  TO COMPLY
WITH ANY  REQUIREMENT  OF LAW.  THE  FOREGOING IS SUBJECT TO THE  PROVISIONS  OF
SECTION 5.1 HEREOF AND SECTION 10.3(a) OF THE PARTICIPATION AGREEMENT.

         8.2. Possession and Use of the Property.  The Property may be used only
for such  purposes as are permitted by Applicable  Law and  consistent  with all
Insurance  Requirements  and in compliance  with any  covenants,  conditions and
restrictions  of record and any ordinance or law affecting the use and occupancy
of the  Property;  and provided  that such uses do not  Materially  increase the
liability,  directly or indirectly, of the Lessor or Materially adversely affect
the value,  utility or  remaining  useful life of the  Property  from that which
would obtain if the Property were to be used as  administration,  manufacturing,
design, research and development and warehouse facilities. The Lessee shall pay,
or cause to be paid, all charges and costs  required in connection  with the use
of the  Property  as  contemplated  by this  Lease and the  Construction  Agency
Agreement.  The Lessee  shall not commit or permit any waste of the  Property or
any part thereof (provided,  that waste shall not include ordinary wear and tear
and damage by fire or other peril).

         10.1.  Maintenance and Repair; Return. (a) Except for ordinary wear and

unforeseen,  in each case as required by all  Requirements  of Law and Insurance
Requirements  and on a basis  consistent  with the operation and  maintenance of
commercial  properties  comparable  in type and  location to the Property and in

         (b) The Lessor  shall under no  circumstances  be required to build any

Specifications  delivered  by the Lessee to the Lessor and the Agent on the Land
Interest Acquisition Date, to be done in connection with any Modification to the
Property the cost of which is anticipated to exceed $500,000 in the aggregate.


                                   ARTICLE XII

         12.1. Warranty of Title. (a) The Lessee agrees that except as otherwise
provided  herein and subject to the terms of Article XIII  relating to permitted
contests, the Lessee shall not directly or indirectly create or allow to remain,
and shall  promptly  discharge at its sole cost and expense,  any Lien,  defect,
attachment,  levy, title retention  agreement or claim upon the Property (or the
Lessor's interest therein) or any Modifications or any Lien, attachment, levy or
claim with  respect




                                      -11-

<PAGE>


to the Rent or with  respect to any  amounts  held by the Agent  pursuant to the
Participation  Agreement or the other Operative Documents,  other than Permitted
Exceptions and Lessor Liens.

         (b) Nothing  contained in this Lease shall be construed as constituting
the  consent or request  of the  Lessor,  expressed  or  implied,  to or for the
performance  by any  contractor,  mechanic,  laborer,  materialman,  supplier or
vendor of any labor or services or for the  furnishing  of any materials for any
construction,  alteration,  addition, repair or demolition of or to the Property
or any part  thereof.  NOTICE IS HEREBY  GIVEN  THAT  NEITHER  THE  LESSOR,  ANY
PARTICIPANT  NOR THE  AGENT IS OR SHALL BE LIABLE  FOR ANY  LABOR,  SERVICES  OR
MATERIALS  FURNISHED OR TO BE  FURNISHED TO THE LESSEE OR TO ANYONE  HOLDING THE
PROPERTY OR ANY PART THEREOF  THROUGH OR UNDER THE LESSEE AND THAT NO MECHANIC'S
OR OTHER LIENS FOR ANY SUCH  LABOR,  SERVICES OR  MATERIALS  SHALL  ATTACH TO OR
AFFECT THE INTEREST OF THE LESSOR IN AND TO THE PROPERTY.

         12.2. Grants and Releases of Easements. Provided that no Lease Event of
Default shall have occurred and be continuing  and subject to the  provisions of
Articles VIII, IX, X and XI, the Lessor hereby  consents in each instance to the
following actions by the Lessee, in the name and stead of the Lessor, but at the
Lessee's  sole  cost and  expense:  (a) the  granting  of  easements,  licenses,
rights-of-way  and other  rights  and  privileges  in the  nature  of  easements
reasonably  necessary or desirable  for the  completion of  construction  of the
Improvements,  use,  repair,  operation or maintenance of the Property as herein
provided; (b) the release of existing easements or other rights in the nature of
easements  which are for the  benefit  of the  Property;  (c) the  execution  of
petitions to have the Property  annexed to any municipal  corporation or utility
district;  and (d) the execution of amendments to any covenants and restrictions
affecting the Property;  provided,  however,  in each case the Lessee shall have
delivered to the Lessor a  Responsible  Officer's  Certificate  stating that (i)
such grant,  release,  dedication  or transfer  does not  materially  impair the
value,  utility  and  remaining  useful life of the  Property,  (ii) such grant,
release,  dedication or transfer is reasonably  necessary in connection with the
completion of  construction of the  Improvements,  use,  operation  maintenance,
alteration  or  improvement  of the  Property,  (iii) the  Lessee  shall  remain
obligated  under  this  Lease and under any  instrument  executed  by the Lessee
consenting to the assignment of the Lessor's  interest in this Lease as security
for  indebtedness,  in each such case in accordance  with their terms, as though
such grant, release, dedication or transfer, had not been effected, and (iv) the
Lessee  shall pay and perform any  obligations  of the Lessor  under such grant,
release, dedication or transfer, and (v) such easements, rights-of-way and other
rights shall be  subordinate  and subject to the Lien of the  Mortgage.  Without
limiting the  effectiveness  of the  foregoing,  provided that no Lease Event of
Default  shall have  occurred  and be  continuing,  the Lessor  shall,  upon the
request of the Lessee,  and at the Lessee's  sole cost and expense,  execute and
deliver any  instruments  necessary  or  appropriate  to confirm any such grant,
release, dedication or transfer to any Person permitted under this Section 12.2.

                                  ARTICLE XIII

         13.1.  Permitted Contests Other Than in Respect of Indemnities.  Except
to the  extent  otherwise  provided  for  in  Section  13 of  the  Participation
Agreement,  the Lessee, on its own or on the Lessor's behalf but at the Lessee's
sole cost and expense,  may contest,  by appropriate  administrative or judicial
proceedings conducted in good faith and with due diligence, the amount, validity
or  application,  in whole or in part,  of any  Requirement  of Law,  or utility
charges  payable  pursuant  to  Section  4.1  or  any  Lien,  attachment,  levy,
encumbrance  or  encroachment,  and the  Lessor  agrees  not to pay,  settle  or
otherwise  compromise  any such item,  provided  that (a) the  commencement  and
continuation of such proceedings shall suspend the collection  thereof from, and
suspend the enforcement thereof against, the Property, the Lessor, the Agent and
the  Participants  or the Lessee  shall have bonded or  otherwise  secured  such
amount in a manner  satisfactory to the Lessor and the Agent; (b) there shall be
no risk of the  imposition of a Lien (other than  Permitted  Exceptions or Liens
for which  adequate  security (in the opinion of the Lessor) for payments in the
event of an unsuccessful contest has been posted) on the Property and no part of
the Property nor any Rent would be in any danger of being sold, forfeited,  lost
or deferred;  (c) at no time during the permitted  contest shall there be a risk
of the  imposition  of criminal  liability  or material  civil  liability on the
Lessor, the Agent or any Participant for failure to comply therewith (unless, in
the case of civil liability,  the Lessee shall have bonded or otherwise  secured
such amount in a manner  satisfactory  to the Lessor and the Agent);  and (d) in
the event that,  at any time,  there shall be a material  risk of extending  the
application  of such item  beyond  the end of the Term,  then the  Lessee  shall
deliver to the Lessor a Responsible Officer's  Certificate  certifying as to the
matters set forth in clauses (a), (b) and (c) of this Section 13.1.  The Lessor,
at the Lessee's  sole cost and expense,  shall execute and deliver to the Lessee
such  authorizations  and other  documents  as may  reasonably  be  required  in
connection  with any such  contest and, if  reasonably  requested by the Lessee,
shall join as a party therein at the Lessee's sole cost and expense.


                                   ARTICLE XIV

         14.1. Public Liability and Workers' Compensation Insurance.  During the
Term, the Lessee shall procure and carry, at the Lessee's sole cost and expense,
commercial general liability insurance,  including  contractual  liability,  for
claims for injuries or death sustained by persons or damage to property while on
the  Property  and such  other  public  liability  coverages  as are  ordinarily
procured by Persons who own or operate  similar  properties and consistent  with
prudent business practice,  which policies shall include  contractual  liability
endorsements covering the Lessee's indemnification  obligations in Section 14.4.
Such  insurance  shall be on terms and in  amounts  (which  shall be  reasonably
acceptable  to the  Lessor  and in the event of  liability  insurance  shall not
require  coverage  in excess of  $10,000,000)  that are no less  favorable  than
insurance  maintained by the Lessee with respect to similar  properties  that it
owns  and that are in  accordance  with  prudent  business  practice  and may be
provided under blanket  policies  maintained by or on behalf of the Lessee.  The
policy shall be endorsed to name the Lessor,  the Agent and each  Participant as
additional insureds.  The policy shall also 



                                      -13-

<PAGE>



specifically provide that the policy shall be considered primary insurance which
shall apply to any loss or claim before any  contribution by any insurance which
the Lessor,  the Agent or the  Participants may have in force. The Lessee shall,
in the  construction  of the  Improvements  and the  operation  of the  Property
(including  in  connection  with  any  Modifications  thereof)  comply  with the
applicable workers'  compensation laws and protect the Lessor, the Agent and the
Participants against any liability under such laws.

         14.2.  Hazard and Other  Insurance.  During the Term,  the Lessee shall
keep, or cause to be kept, the Property  insured against loss or damage by fire,
flood,  and other risks typically  included in policies in the state of Colorado
for  facilities  similar  to the  Property  in an amount  not less than the then
current  replacement  cost of the  buildings  and  improvements  on the Property
(provided,  that the Lessee's  flood  insurance  may have a sublimit of not less
than  $50,000,000)  and on  terms  that  are no less  favorable  than  insurance
covering  other similar  properties  owned or leased by the Lessee or any of its
Affiliates and that are in accordance with prudent business practice. The Lessee
may provide such  coverage  under  blanket  policies  maintained  by the Lessee.
During the  construction  of any  Improvements  the Lessee  shall also  maintain
builders'  risk  insurance.  Each policy of insurance  maintained  by the Lessee
pursuant to this  Section  14.2 shall  provide  that all  insurance  proceeds in
respect of any loss or  occurrence  shall be paid to and adjusted  solely by the
Lessee  except  from and after the date on which the  insurer  receives  written
notice  from the Lessor or the Agent that a Lease  Event of Default  exists (and
unless and until such  insurer  receives  written  notice from the Lessor or the
Agent that all Lease  Events of Default  have been  cured),  all losses shall be
adjusted  solely by, and all  insurance  proceeds  shall be paid  solely to, the
Agent (or the Lessor if the  Participation  Interests  have been fully paid) for
application pursuant to Article XV.

         14.3.  Coverage.  (a) The Lessee shall furnish the Lessor and the Agent
with certificates showing the insurance required under Sections 14.1 and 14.2 to
be in effect and naming the Lessor, the Agent and each Participant as additional
insureds and, with respect to the insurance  required  under Section 14.2,  loss
payees along with the Lessee,  as their  respective  interests  may appear,  and
showing  the  mortgagee  endorsement  required  by  Section  14.3(c).  All  such
insurance  shall be at the cost and  expense of the  Lessee.  Such  certificates
shall include a provision for thirty (30) days'  advance  written  notice by the
insurer  to the  Lessor  and the  Agent in the event of  cancellation  of or any
reduction  to less  than  90% of  Replacement  Value  (or,  in the case of Flood
insurance,  less than 90 percent of the sublimit  specified in Section  14.2) in
the coverage provided by such insurance.

         (b) The Lessee agrees that the insurance policy or policies required by
Sections 14.1 and 14.2 shall include (i) a clause in substantially the following
form pursuant to which such policy shall provide that it will not be invalidated
should the  Lessee  waive,  in  writing,  prior to a loss,  any or all rights of
recovery  against  any party for  losses  covered by such  policy,  and that the
insurance  in favor of the  Lessor,  the Agent and the  Participants,  and their
respective  rights under and interests in said policies shall not be invalidated
or  reduced  by any act or  omission  or  negligence  of the Lessee or any other
Person  having any  interest in the  Property,  and (ii) a so-called  "Waiver of
Subrogation  Clause".  The Lessee hereby waives any and all such rights  against
the Lessor,  the Agent and the Participants to the extent of payments 



                                      -14-

<PAGE>

made under such  policies.  The Lessor,  the Agent and the  Participants  hereby
waive all such rights  against the Lessee to the extent of payments  made to the
Lessor under any of such policies.

         (c)  All  such  insurance  shall  be  written  by  reputable  insurance
companies  that are  financially  sound and  solvent  and  otherwise  reasonably
appropriate  considering the amount and type of insurance being provided by such
companies. Any insurance company selected by the Lessee which is rated in Best's
Key Rating Guide or any successor  thereto (or if there be none, an organization
having a similar national  reputation) shall have a general  policyholder rating
of "A-" and a financial  rating of at least 10 in Best's Key Rating  Guide or be
otherwise acceptable to the Lessor, the Agent and the Required Participants. All
insurance  policies  required  by  Section  14.2 shall  include a standard  form
mortgagee endorsement in favor of the Agent.

         (d) The Lessor shall not carry separate insurance concurrent in kind or
form or contributing in the event of loss with any insurance required under this
Article XIV except that the Lessor may carry  separate  liability  insurance (at
its sole cost) so long as (i) the Lessee's  insurance is  designated  as primary
and in no event excess or  contributory  to any insurance the Lessor may have in
force which would apply to a loss  covered  under the  Lessee's  policy and (ii)
each such insurance policy will not cause the Lessee's  insurance required under
this Article XIV to be subject to a coinsurance exception of any kind.

         (e) The  Lessee  shall  pay as they  become  due all  premiums  for the
insurance  required by Section 14.1 and Section 14.2, and shall renew or replace
each policy prior to the  expiration  date thereof.  Throughout the Term, at the
time each of the  Lessee's  insurance  policies is renewed (but in no event less
frequently than once each year),  the Lessee shall deliver to the Lessor and the
Agent  certificates of insurance  evidencing that all insurance required by this
Article XIV is being  maintained  by the Lessee with respect to the Property and
is in effect.

         (f)  Notwithstanding  the other  provisions  of this  Article  XIV, the
Lessee may  provide  the  insurance  coverage  required  under this  Article XIV
through its self-insurance  program, so long as the Lessee remains in compliance
with the Tangible Net Worth covenant in Section 10.1(r)(ii) of the Participation
Agreement.

         (g) Notwithstanding anything to the contrary contained in the Operative
Documents: (A) the Lessee hereby waives, releases and discharges the Lessor, the
Agent and each  Participant  and their  agents  and  employees  from all  claims
whatsoever  arising  out of loss,  claim,  expense  or damage to or  destruction
covered  or   coverable   by   insurance   required   under  this   Article  XIV
notwithstanding that such loss, claim, expense or damage may have been caused by
the Lessor,  the Agent or any  Participant  or any of their agents or employees,
and the Lessee  agrees to look to the  insurance  coverage  only in the event of
such loss;  and (B) the Lessor,  the Agent and the  Participants  hereby  waive,
release and discharge  the Lessee and its agents and  employees  from all claims
whatsoever  arising out of loss,  claim,  expense,  or damage to or  destruction
covered by insurance  required  under this Article XIV to the



                                      -15-

<PAGE>


extent of payments  made to the Lessor  notwithstanding  that such loss,  claim,
expense  or damage  may have been  caused by the  Lessee or any of its agents or
employees.

         14.4.  Indemnification.  In addition to the indemnification  provisions
provided for in Section 13 of the Participation Agreement, to the fullest extent
allowed by law, the Lessee shall at all times during the Term, and to the extent
resulting  from acts or events  occurring  prior to or during the Term or during
any other period when the Lessee is in  possession  and control of the Property,
indemnify, defend and hold each Indemnitee harmless against and from any and all
Claims  by or on behalf  of any  Person  arising  from the  construction  of the
Improvements  or conduct or  management,  or from any work or things  whatsoever
done in or about the Property, and will further indemnify,  defend and hold each
Indemnitee  harmless against and from any and all Claims arising during the Term
of this Lease,  from any  condition of the  Property,  the  Improvements  or any
street, curb or sidewalk adjoining the Property,  or of any passageways or space
therein or  appurtenant  thereto,  or arising  from any breach or default on the
part of the Lessee in the  performance  of any covenant or agreement on the part
of the  Lessee  to be  performed,  pursuant  to the  terms of this  Lease or the
Construction  Agency  Agreement,  or arising from any act or  negligence  of the
Lessee,  its agents,  servants,  employees  or  licensees,  or arising  from any
accident,  injury or damage whatsoever caused to any Person occurring during the
term of this Lease, in or about the Property,  or upon the sidewalk and the land
adjacent  thereto,  other  than in any of the  foregoing  cases  (a)  any  Claim
resulting  from a voluntary act or omission of the  Indemnitee not in compliance
with any of the terms of the Operative  Documents not caused by or  attributable
to acts or omissions of the Lessee or any third party who is not an Affiliate or
an employee, agent or contractor of an Indemnitee or its Affiliates, and (b) any
Claim  resulting  from  the  gross  negligence  or  willful   misconduct  of  an
Indemnitee. Any action, suit or proceeding in respect of any such Claim shall be
handled in the manner set forth in Section 13.4 of the Participation Agreement.


                                   ARTICLE XV

         15.1. Casualty and Condemnation.  (a) Subject to the provisions of this
Article XV and Article XVI (in the event the Lessee delivers, or is obligated to
deliver,   a  Termination   Notice),   and  except  during  the  occurrence  and
continuation  of a Lease  Default,  the Lessee shall be entitled to receive (and
the Lessor shall pay over to the Lessee,  if received by the Lessor,  and hereby
irrevocably  assigns to the Lessee all of the Lessor's right, title and interest
in) any award,  compensation  or  insurance  proceeds to which the Lessee or the
Lessor  may  become  entitled  by reason of their  respective  interests  in the
Property  (i) if all or a portion of the  Property  is damaged or  destroyed  in
whole or in part by a Casualty or (ii) if the use, access,  occupancy,  easement
rights  or title  to the  Property  or any part  thereof,  is the  subject  of a
Condemnation;  provided,  however, if a Lease Default shall have occurred and be
continuing,  such  award,  compensation  or  insurance  proceeds  shall  be paid
directly to the Agent or, if received by the Lessee,  shall be held in trust for
the  Agent,  and shall be paid  over by the  Lessee  to the  Agent  (or,  if the
Participation  Interests  have  been  fully  paid,  to the  Lessor)  and held in
accordance with the terms of this paragraph (a). If, contrary to such 



                                      -16-

<PAGE>

provision,  any such award,  compensation or insurance  proceeds are paid to the
Lessor or the Lessee,  rather than to the Agent,  the Lessor and the Lessee,  as
the case may be,  hereby agree to transfer  any such  payment to the Agent.  All
amounts held by the Lessor or the Agent when a Lease Default exists hereunder on
account of any award, compensation or insurance proceeds either paid directly to
the Lessor or the Agent or turned over to the Lessor or the Agent  shall  either
be (i) paid to the Lessee for the repair of damage  caused by such  Casualty  or
Condemnation in accordance with paragraph (e) of this Section 15.1, or (ii) held
in an  interest  bearing  account  reasonably  acceptable  to the Lessor and the
Lessee until  applied to the purchase  price of the Property on the  Termination
Date, with any Excess Proceeds being payable to the Lessee.

         (b) The  Lessee may appear in any  proceeding  or action to  negotiate,
prosecute,  adjust or appeal any claim for any award,  compensation or insurance
payment  on  account  of any such  Casualty  or  Condemnation  and shall pay all
expenses thereof. At the Lessee's  reasonable request,  and at the Lessee's sole
cost and  expense,  the  Lessor  and the  Agent  shall  participate  in any such
proceeding,  action, negotiation,  prosecution or adjustment. The Lessor and the
Lessee  agree that this  Lease  shall  control  the rights of the Lessor and the
Lessee in and to any such award, compensation or insurance payment.

         (c) If the Lessor or the Lessee shall  receive  notice of a Casualty or
of an actual, pending or threatened Condemnation of the Property or any interest
therein, the Lessor or the Lessee, as the case may be, shall give notice thereof
to the other and to the Agent promptly after the receipt of such notice.

         (d) In the event of a  Casualty  or  receipt of notice by the Lessee or
the Lessor of a Condemnation, the Lessee may deliver to the Lessor and the Agent
a Termination  Notice with respect to the Property  pursuant to Section 16.1. If
the Lessee does not deliver a Termination  Notice within  seventy-five (75) days
after  such  occurrence,  then  this  Lease  shall  (subject  to the  terms  and
conditions  thereof)  remain in full force and effect,  and the Lessee shall, at
the Lessee's sole cost and expense, promptly and diligently restore the Property
pursuant to paragraph (e) of this Section 15.1 and otherwise in accordance  with
this Lease. If the Lessee delivers a Termination Notice within seventy-five (75)
days after such occurrence,  a Significant  Event shall irrevocably be deemed to
have occurred with respect to the Property, and, in such event, this Lease shall
terminate  and the Lessee  shall  purchase the Property on the next Payment Date
(but in no event later than  seventy-five  (75) days after such  occurrence)  (a
"Termination Date") pursuant to Article XVI hereof.

         (e) If pursuant to this Section 15.1 this Lease shall  continue in full
force and effect following a Casualty or Condemnation,  the Lessee shall, at its
sole cost and expense (and, without  limitation,  if any award,  compensation or
insurance  payment is not sufficient to restore the Property in accordance  with
this  paragraph,  the Lessee shall pay the  shortfall),  promptly and diligently
repair any damage to the Property  caused by such  Casualty or  Condemnation  or
substitute  new  Equipment  for the affected  Equipment in  conformity  with the
requirements   of  Sections   10.1  and  11.1  using  the  as-built   Plans  and
Specifications  for the Property  (as modified to give effect to any  subsequent
Modifications,  any  Condemnation 



                                      -17-

<PAGE>


affecting the Property and all applicable  Requirements of Law) so as to restore
the Property to at least the same  condition,  operation,  function and value as
existed  immediately  prior to such  Casualty  or  Condemnation;  provided,  the
substitution  of any  Equipment  for  any  such  affected  Equipment  previously
financed with an Advance shall, at the Lessor's  reasonable  request, be subject
to delivery of an independent  third-party appraisal reasonably  satisfactory to
the Lessor and the Required  Participants  by an appraiser  satisfactory  to the
Lessor and the  Required  Participants  showing  both (i) a current  Fair Market
Sales Value and (ii)  expected  Fair Market  Sales Value as of the then  current
Expiration Date and the dates on which any potential  Renewal Term would expire,
in each  case  equal to or  greater  than  such  values  at such  dates  for the
Equipment  being  replaced.  In the  event  of such  restoration,  title  to the
Property  shall  remain  with the Lessor;  provided,  that (i) title to any such
substituted  equipment shall vest in the Lessor in the event that such equipment
replaces Equipment  previously financed with an Advance and such equipment shall
constitute  Equipment  thereafter  for all purposes of this Lease,  and (ii) the
Lessor  shall  assign all of its right,  title and interest to the Lessee in any
such  replaced  equipment in the event that such  equipment  replaces  Equipment
previously  financed with an Advance without  representation  or warranty of any
kind other than that such equipment is free of Lessor Liens.  Upon completion of
such restoration, the Lessee shall furnish the Lessor an architect's certificate
of substantial  completion and a Responsible  Officer's  Certificate  confirming
that such restoration has been completed pursuant to this Lease.

         (f) In no event shall a Casualty or Condemnation  with respect to which
this Lease  remains in full force and effect  under this Section 15.1 affect the
Lessee's  obligations  to pay Rent  pursuant  to Section  3.1 or to perform  its
obligations  and pay any  amounts  due on the  Expiration  Date or  pursuant  to
Articles XIX and XX.

         (g) Any Excess Proceeds  received by the Lessor or the Agent in respect
of a Casualty or Condemnation shall be turned over to the Lessee,  provided that
no Lease Event of Default or Lease Default has occurred and is  continuing.  Any
Excess  Proceeds which are not turned over to the Lessee due to the existence of
a Lease  Event of  Default  or a Lease  Default  shall be  applied  against  the
Lessee's  obligations  under the  Lease,  and any  excess  remaining  after such
obligations have been satisfied shall be paid to the Lessee.

         15.2.   Environmental  Matters.   Promptly  upon  the  Lessee's  actual
knowledge of the presence of Hazardous Substances in any portion of the Property
in concentrations and conditions that constitute an Environmental Violation, the
Lessee  shall  notify the Lessor in writing of such  condition.  In the event of
such Environmental  Violation, the Lessee shall, not later than thirty (30) days
after the Lessee has actual knowledge of such Environmental  Violation,  either,
if such Environmental  Violation is a Significant  Event,  deliver to the Lessor
and the Agent a Responsible  Officer's Certificate and a Termination Notice with
respect to the  Property  pursuant to Section  16.1,  or, if such  Environmental
Violation is not a  Significant  Event,  at the Lessee's  sole cost and expense,
promptly and diligently  commence any Response Actions necessary to investigate,
remove, clean up or remediate the Environmental Violation in accordance with the
terms of Section 9.1. If the Lessee does not deliver a  Termination  Notice with
respect to the  Property  pursuant  to Section  16.1,  the  Lessee  shall,  upon




                                      -18-

<PAGE>



completion  of  Response  Actions  by the  Lessee,  cause to be  prepared  by an
environmental consultant reasonably acceptable to the Lessor a report describing
the Environmental Violation and the Response Actions taken by the Lessee (or its
agents) for such Environmental Violation, and a statement by the consultant that
the  Environmental  Violation  has been  remedied in  compliance in all material
respects with applicable  Environmental Law. Each such  Environmental  Violation
shall be remedied prior to the Expiration Date. Nothing in this Article XV shall
reduce or limit the Lessee's  obligations  under Sections 13.1,  13.2 or 13.3 of
the Participation Agreement.

         15.3.  Notice  of  Environmental  Matters.  Promptly,  but in any event
within  the  thirty  (30)  Business  Days from the date the  Lessee  has  actual
knowledge thereof,  the Lessee shall provide to the Lessor written notice of any
material  pending  or  threatened  claim,  action or  proceeding  involving  any
Environmental Law or any Release on or in connection with the Property. All such
notices shall describe in reasonable  detail the nature of the claim,  action or
proceeding and the Lessee's proposed response thereto.  In addition,  the Lessee
shall provide to the Lessor, within thirty (30) Business Days of receipt, copies
of all material written  communications with any Governmental Authority relating
to any Environmental Law in connection with the Property.  The Lessee shall also
promptly provide such detailed reports of any such Material environmental claims
as may reasonably be requested by the Lessor and the Agent.

         16.1. Termination by the Lessee upon Certain Events. If either: (i) the
Lessee or the  Lessor  shall have  received  notice of a  Condemnation,  and the
Lessee shall have  delivered to the Lessor a Responsible  Officer's  Certificate
that such Condemnation is a Significant Condemnation; or (ii) a Casualty occurs,
and the  Lessee  shall have  delivered  to the  Lessor a  Responsible  Officer's
Certificate  that  such  Casualty  is  a  Significant   Casualty;  or  (iii)  an
Environmental  Violation  occurs or is  discovered  and the  Lessee  shall  have
delivered to the Lessor a Responsible Officer's Certificate stating that, in the
reasonable,  good-faith  judgment of the Lessee,  the cost to remediate the same
will cause the same to be a Significant  Event,  or (iv) if the Lessee shall not
have delivered a Termination Notice with respect to such Environmental Violation
described  in clause  (iii) but the  requirements  of Section  16.4 are met with
respect  to  such   Environmental   Violation;   then,  (A)  the  Lessee  shall,
simultaneously  with  the  delivery  of the  Responsible  Officer's  Certificate
pursuant to the preceding  clause (i), (ii) or (iii) deliver a written notice in
the form described in Section 16.2(a) (a "Termination Notice"), or (B) if clause
(iv) is  applicable,  the Lessor may deliver a  Termination  Notice  pursuant to
Section 16.4; provided,  that if such Environmental  Violation was not caused by
nor  within the  control of the  Lessee,  the  Lessee  may  exercise  either its
Purchase Option or Remarketing Option pursuant to Section 17.2(h).

         16.2. Procedures. (a) A Termination Notice shall contain: (i) notice of
termination  of this Lease with respect to the Property or the affected  portion
thereof on a date that is no later than thirty (30) days after the occurrence of
the applicable event described in clause (i), (ii) or


                                      -19-

<PAGE>


(iii) of Section 16.1 (the "Termination Date"), such termination to be effective
upon the Lessee's  payment of the Asset  Termination  Value (or portion  thereof
representing  the Property Cost of the affected  portion of the  Property);  and
(ii) a  binding  and  irrevocable  agreement  of the  Lessee  to pay  the  Asset
Termination Value and purchase the Property on the Termination Date.

         (b) On the  Termination  Date,  the Lessee  shall pay to the Lessor the
Asset Termination Value (or such portion thereof, as applicable), plus all other
amounts owing in respect of Rent for the Property (including  Supplemental Rent)
theretofore  accruing,  and the Lessor shall convey the Lessor's interest in the
Property or such portion thereof to the Lessee (or the Lessee's designee) all in
accordance  with Section  19.1,  as well as any Net Proceeds with respect to the
Casualty  or  Condemnation  giving  rise to the  termination  of this Lease with
respect to the Property theretofore received by the Lessor.

         16.3.  Termination  by the Lessor upon  Certain  Events.  If the Lessor
reasonably determines that any change in, or change by a Governmental  Authority
in the  interpretation of, any applicable law after the date hereof would result
in it or any  Participant  being unable to continue to hold legal or  beneficial
title to all or any portion of the  Property  or,  except as provided in Section
16.4 hereof,  subject it or any  Participant  to onerous  regulations or onerous
liability on account thereof,  the Lessor may deliver a Termination  Notice with
respect  to the  Lease to the  Agent,  the  Participants  and the  Lessee,  such
termination to be effective on the  Termination  Date specified  therein,  which
date  shall  not be  earlier  than 30 days  following  the  date the  notice  is
delivered  to the  Lessee.  In the event the Lessor  exercises  its  termination
option,  the Lessee may exercise the Remarketing Option provided in Section 22.1
hereof by giving  notice to the Lessor  within ten (10) Business Days of receipt
of the notice from the Lessor.  If the Lessee does not exercise its  Remarketing
Option,  the Lessee shall be  obligated  to purchase the Property in  accordance
with Section  20.2 hereof on the  Termination  Date for the  purchase  price set
forth therein.


         16.4.  Purchase of  Property.  Upon  receipt of any notice  pursuant to
Section 15.2 or 15.3, the Lessor or the Required  Participants,  at the Lessee's
expense, shall have the right to select an independent  environmental consultant
acceptable to the Lessee, which acceptance shall not be unreasonably withheld or
delayed,  to  determine  the  estimated  cost  of  conducting  any  clean-up  or
remediation  required as a result of the  Environmental  Violation  disclosed in
such notice. If such independent  environmental  consultant  determines that the
cost of any such clean-up or  remediation  would exceed  $5,000,000,  the Lessor
shall,  subject to the proviso at the end of Section  16.1,  at the direction of
the Required Participants,  by written notice require the Lessee to purchase, or
arrange for an Affiliate  or other third party to purchase,  the Property on the
Expiration Date by delivering a Termination Notice following the requirements of
Section 16.2 hereof,  unless the  Environmental  Violation was not caused by nor
within the control of the Lessee,  in which later case the provisions of Section
17.2(h) shall apply.

about or be effected by  operation of law or pursuant to or in  compliance  with
any judgment,  decree or order of any court or any order,  rule or regulation of

         (c) the Lessee shall fail to maintain  insurance as required by Article
XIV of this  Lease,  and such  failure  is either a  failure  to have in force a
policy of insurance substantially meeting the requirements of Article XIV, or if
such  policy  is  in  effect,  then  any  deviation  of  such  policy  from  the
requirements  of  Article  XIV is not cured  within  twenty(20)  days  after the
earlier  of (i)  receipt  of written  notice  thereof or (ii) the Lessee  having
knowledge thereof;

         (d) the Lessee  shall fail to observe or perform any term,  covenant or

or  inaccurate  in any Material  way, and such failure or  misrepresentation  or
breach of warranty  shall remain  uncured for a period of thirty (30) days after
receipt of written notice thereof;  provided, that if such failure to perform is
not  capable of being  cured  within  such  period but is capable of being cured
within one hundred  eighty (180) days after the  occurrence  of such default and
the Lessee is proceeding  diligently  to cure such default,  the Lessee shall be
entitled to request an additional period (not to exceed one hundred eighty (180)
days from the date of such default) to cure such default;

any of its  Subsidiaries  to any  Participant)  and such failure shall continued
beyond any period of grace provided with respect  thereto,  or (B) shall fail to
make any other  payment or payments  when due under or otherwise  default in the

the holder or holders thereof to cause,  indebtedness in an aggregate  amount of
$10,000,000 or more to become due prior to its stated date of maturity;  or (ii)
there shall occur to exist any other event or condition which causes, or permits
the  holder  or  holders  of such  indebtedness  to  cause,  indebtedness  in an
aggregate  amount of  $10,000,000 or more to become due prior to its stated date
of maturity (whether through holder puts,  mandatory  redemptions or prepayments

substantial  part of its  property,  (ii) be  unable,  or admit in  writing  its

assignment for the benefit of it or any of its  creditors,  (iv) be dissolved or
liquidated  in full or in part,  (v) no  longer  be  Solvent;  (vi)  commence  a
voluntary case or other proceeding seeking liquidation,  reorganization or other

excess of  $10,000,000  (exclusive  of amounts  which are  covered by  insurance
issued by an insurer satisfying the requirements set forth in Section 10.1(d) of

to  Section  20.1  hereof  and the  Lessee  shall  have  validly  exercised  its
Remarketing Option pursuant to Section 22.1 hereof, the Lessee shall have failed
(A) to consummate a sale of the Property in the manner  provided  therein on the
Expiration  Date and to pay to the Agent (or such other  Person as the Agent may
direct)  pursuant to such Section the Residual  Value  Guarantee  Amount and the
other amounts required thereby,  or (B) to purchase the Lessor's interest in the
Property on the Expiration Date as provided in Section 20.2 hereof and to pay to

         (n) the Lessee shall have abandoned or constructively  abandoned all or

days; or

         (o) an  Environmental  Violation  shall occur that,  in the  reasonable
opinion of the Lessor and the Required  Participants,  based on an Environmental
Audit,  constitutes a Significant  Event and the Lessee shall not, within thirty
(30) days after notice from the Lessor, have delivered a Termination Notice with
respect thereto pursuant to Section 16.1 hereof or, if so delivered,  repurchase
of the Property shall not have been consummated on the Termination Date pursuant
to Section 16.2 hereof; or

         (p) the Lessee  shall have  elected to or be required  to purchase  the

have been consummated on the Termination Date pursuant to either such Section.



         17.2.  Remedies.  Upon the occurrence of any Lease Event of Default and
at any time  thereafter,  the Lessor may, so long as such Lease Event of Default
is  continuing,  do one or more  of the  following  as the  Lessor  in its  sole
discretion  shall  determine,  without  limiting  any other  right or remedy the
Lessor may have on account of such Lease  Event of Default  (including,  without
limitation,  the  obligation of the Lessee to purchase the Property as set forth
in Section  20.3)  upon  notice to the Lessee  (if not  otherwise  provided  for
below):

         (a) The Lessor may, by notice to the Lessee,  rescind or terminate this
Lease only as to all of the  Property as of the date  specified  in such notice;
however,  (i) no reletting,  reentry or taking of possession of the Property (or
any  portion  thereof)  by the Lessor  will be  construed  as an election on the
Lessor's part to terminate  this Lease unless a written notice of such intention
is given to the Lessee, (ii) notwithstanding any reletting, reentry or taking of
possession,  the Lessor may at any time thereafter elect to terminate this Lease
for a  continuing  Lease  Event of  Default,  (iii) no act or thing  done by the
Lessor or any of its  agents,  representatives  or  employees  and no  agreement
accepting a surrender of the Property  shall be valid unless the same be made in
writing  and  executed  by the Lessor and (iv) no  termination  pursuant to this
Section shall  terminate  Lessee's right to cure such Lease Event of 


                                      -23-

<PAGE>


Default set forth in Section 17.6 hereof by purchasing the Property  pursuant to
Section  20.1  hereof  prior to such time as a  foreclosure  upon or sale of the
Property has been completed.

         (b) The Lessor may (i) demand  that the  Lessee,  and the Lessee  shall
upon the  written  demand of the  Lessor,  return the  Property  promptly to the
Lessor in the manner and condition required by, and otherwise in accordance with
all of the provisions of, Articles VIII, IX and X hereof as if the Property were
being  returned at the end of the Term,  and the Lessor  shall not be liable for
the  reimbursement  of the Lessee  for any costs and  expenses  incurred  by the
Lessee in connection  therewith  and (ii) without  prejudice to any other remedy
which the Lessor may have for possession of the Property,  and to the extent and
in the manner  permitted  by  Applicable  Law,  enter upon the Property and take
immediate  possession  of (to the  exclusion  of the Lessee) the Property or any
part  thereof  and expel or remove the  Lessee  and any other  Person who may be
occupying  the  Property,  by summary  proceedings  or  otherwise,  all  without
liability to the Lessee for or by reason of such entry or taking of  possession,
whether  for the  restoration  of damage to  property  caused by such  taking or
otherwise and, in addition to the Lessor's  other damages,  to the extent and in
the manner  permitted by Applicable Law with respect to remedies for a breach of
a real estate lease,  the Lessee shall be responsible for all costs and expenses
incurred by the Lessor and/or the Agent or the  Participants  in connection with
any reletting, including, without limitation, brokers' fees and all costs of any
alterations or repairs made by the Lessor;

         (c) The Lessor may (i) sell all or any part of the  Property  at public
or private  sale, as the Lessor may  determine,  free and clear of any rights of
the Lessee and without  any duty to account to the Lessee  with  respect to such
action or inaction or any proceeds  with respect  thereto  (except to the extent
required by clause (ii) below if the Lessor  shall elect to exercise  its rights
thereunder)  in which event the Lessee's  obligation to pay Basic Rent hereunder
for  periods  commencing  after the date of such  sale  shall be  terminated  or
proportionately  reduced,  as the case may be; and (ii) if the  Lessor  shall so
elect, demand that the Lessee pay to the Lessor, and the Lessee shall pay to the
Lessor,  on the date of such sale, as  liquidated  damages for loss of a bargain
and not as a penalty (the parties  agreeing  that the  Lessor's  actual  damages
would  be  difficult  to  predict,  but the  aforementioned  liquidated  damages
represent a reasonable  approximation of such amount) (in lieu of Basic Rent due
for periods commencing on or after the Payment Date coinciding with such date of
sale  (or,  if the sale  date is not a  Payment  Date,  the  Payment  Date  next
preceding the date of such sale)), an amount equal to (A) the excess, if any, of
(1) the Asset  Termination  Value  calculated as of such Payment Date (including
all Rent due and unpaid to and including  such Payment  Date),  over (2) the net
proceeds of such sale,  if any (that is, after  deducting all costs and expenses
incurred  by the  Lessor,  the  Agent  and  the  Participants  incident  to such
conveyance,   including,  without  limitation,   repossession  costs,  brokerage
commissions,  prorations,  transfer taxes, fees and expenses for counsel,  title
insurance  fees,  survey  costs,  recording  fees,  and any repair or alteration
costs);  plus (B) interest at the Overdue Rate on the foregoing amount from such
Payment Date until the date of payment, and any excess of the sale proceeds over
such Asset  Termination  Value and any other sums owing by the Lessee  under the
Operative Documents shall be remitted to the Lessee;


                                      -24-

<PAGE>


         (d) The Lessor may, at its option, not terminate the Lease with respect
to the Property, and continue to collect all Basic Rent,  Supplemental Rent, and
all other amounts due the Lessor  (together  with all costs of  collection)  and
enforce the  Lessee's  obligations  under this Lease as and when the same become
due,  or are  to be  performed,  and at the  option  of  the  Lessor,  upon  any
abandonment of the Property by the Lessee or re-entry of same by the Lessor, the
Lessor may, in its sole and absolute  discretion,  elect not to  terminate  this
Lease and may make such reasonable alterations and necessary repairs in order to
relet the Property,  and relet the Property or any part thereof for such term or
terms (which may be for a term  extending  beyond the Term of this Lease) and at
such rental or rentals and upon such other terms and conditions as the Lessor in
its reasonable  discretion may deem advisable;  and upon each such reletting all
rentals actually  received by the Lessor from such reletting shall be applied to
the Lessee's  obligations  hereunder and the other  Operative  Documents in such
order,  proportion and priority as the Lessor may elect in the Lessor's sole and
absolute  discretion.  If such rentals  received from such reletting  during any
period be less than the Rent with respect to the Property to be paid during that
period  by the  Lessee  hereunder,  the  Lessee  shall  pay any  deficiency,  as
calculated by the Lessor, to the Lessor on the next Payment Date;

         (e) Unless the Property has been sold in its entirety,  the Lessor may,
whether or not the Lessor shall have  exercised or shall  thereafter at any time
exercise any of its rights under  paragraph (b), (c) or (d) of this Section 17.2
with respect to the Property or portions  thereof,  demand, by written notice to
the Lessee  specifying  a date (a  "Termination  Date") not earlier than 10 days
after the date of such notice,  that the Lessee  purchase,  on such  Termination
Date,  the Property (or the remaining  portion  thereof) in accordance  with the
provisions of Article XIX and Section 20.3;

         (f) The  Lessor  may  exercise  any other  right or remedy  that may be
available to it under the Operative Documents or otherwise under Applicable Law,
or proceed by appropriate court action (legal or equitable) to enforce the terms
hereof or to  recover  damages  for the  breach  hereof.  Separate  suits may be
brought to collect any such damages for any period(s),  and such suits shall not
in any manner  prejudice the Lessor's  right to collect any such damages for any
subsequent  period(s),  or the Lessor  may defer any such suit  until  after the
expiration  of the Term,  in which  event  such suit shall be deemed not to have
accrued until the expiration of the Term; or

         (g) The Lessor may retain and apply  against the  Lessor's  damages all
sums which the Lessor would,  absent such Lease Event of Default, be required to
pay to, or turn over to, the Lessee pursuant to the terms of this Lease.

         (h)  Notwithstanding  anything contained in this Lease to the contrary,
in the event that (A) the Lease Event of Default  resulting  in the  exercise of
remedies by the Lessor  hereunder is solely the result of a Construction  Agency
Agreement Event of Default pursuant to Section 5.1(b) or (c) of the Construction
Agency  Agreement or is a Lease Event of Default under Section 17.1(o) where the
occurrence  of such  Environmental  Violation  was not  caused by or within  the
control of the  Lessee or under  Section  10.1(d)  (each,  a"Specified  Event of
Default"),  or (B) the




                                      -25-

<PAGE>


proviso at the end of Section 16.1 applies,  the Lessee shall have the option to
(i) remarket the Property for one hundred eighty (180) days after the occurrence
of such Specified Event of Default in accordance with Article XXII (which period
shall constitute the Remarketing  Period),  with the purchase of the Property to
be  consummated  no later than the date that is one  hundred  eighty  (180) days
following the  occurrence of such  Specified  Event of Default (which date shall
constitute  the Expiration  Date if such option is exercised),  or (ii) exercise
its Purchase Option under Section 20.1, with the purchase of the Property by the
Lessee to be consummated,  and the other payments required thereunder to be made
to the  Lessor,  on the next  Payment  Date  following  the  occurrence  of such
Specified  Event of Default (which date shall  constitute the Expiration Date if
such option is  exercised).  The Lessee shall notify the Lessor  within ten (10)
days after the occurrence of such Specified  Event of Default which option it is
exercising.  If the Lessee  elects to remarket the Property the Lessee shall pay
to the Lessor (i) the maximum  Residual  Value  Guarantee  Amount on the date it
furnishes such notice of exercise of the Remarketing  Option (the "Option Notice
Date"), (ii) all breakage costs incurred by the Participants for the duration of
all then current Interest Periods under the Participation Agreement with respect
to the amount so paid following  notices thereof by the Agent,  (iii) Basic Rent
with  respect to the  Tranche A  Participation  Interests  on the amount so paid
accrued to and payable on the Option Notice Date,  (iv) Basic Rent when due with
respect to the unpaid portion of the Tranche B  Participation  Interests  and/or
Tranche C  Participation  Interests  to the date of sale of the Property and (v)
the other payments  required under Section 22.1 when required  thereunder and no
later than the Expiration Date. If the Lessee exercises  neither of such options
or, if one of such  options is  exercised  but the Lessor  does not  receive the
payments  required  above or by such Article or Section on the dates referred to
above, such failure to exercise or failure to receive payment shall constitute a
Lease Event of Default  that is not a Specified  Event of Default and the Lessor
shall be entitled to exercise any of its remedies set forth in Sections  17.2(a)
- - (g).  If the Lessee  properly  exercises  its  Remarketing  Option  under this
Section 17.2(h),  pays the Residual Value Guarantee Amount as required above and
is unable to arrange for the sale of the  Property on the new  Expiration  Date,
such failure to sell the Property shall constitute a Lease Event of Default that
is not a Specified Event of Default and the Lessor shall be entitled to exercise
any of its remedies set forth in Sections  17.2(a) - (g);  provided that in such
event the portion of Asset  Termination  Value which may be  recovered  from the
Lessee  under any of such  Sections  shall not exceed,  in addition to any other
payments required by such Sections,  that portion of the Asset Termination Value
that remains  unpaid after  payment of the Residual  Value  Guarantee  Amount as
provided in this Section 17.2(h).

         17.3.  Waiver of  Certain  Rights.  If this Lease  shall be  terminated
pursuant to Section 17.2, the Lessee waives,  to the fullest extent permitted by
law,  (a) any notice of  re-entry or the  institution  of legal  proceedings  to
obtain  re-entry  or  possession;  (b) any  right  of  redemption,  re-entry  or
repossession;  (c) the benefit of any laws now or hereafter  in force  exempting
property from liability for rent or for debt or limiting the Lessor with respect
to the  election of remedies;  and (d) any other  rights  which might  otherwise
limit or modify any of the Lessor's rights or remedies under this Article XVII.

         17.4.  Power  of Sale and  Foreclosure.  In the  event  that a court of
competent  jurisdiction  rules that this Lease  constitutes a mortgage,  deed of
trust or other  secured  financing  as is the intent of the parties  pursuant to
Section 7.1,  and subject to the  availability  of such remedy under  applicable
law,  then the Lessor and the Lessee agree that (i) the Lessee  hereby  grants a
Lien against the Property WITH POWER OF SALE,  and that,  upon the occurrence of
any Lease Event of Default the Lessor shall have the power and authority, to the
extent  provided by law,  after  proper  notice and lapse of such time as may be
required by law, to sell the Property at the time and place of sale fixed by the
Lessor in said notice of sale, either as a whole, or in separate lots or parcels
or items and in such order as the Lessor  may elect,  at auction to the  highest
bidder  for cash in lawful  money of the  United  States  payable at the time of
sale;  accordingly,  it is acknowledged that A POWER OF SALE HAS BEEN GRANTED IN
THIS  INSTRUMENT;  A POWER OF SALE MAY ALLOW THE LESSOR TO TAKE THE PROPERTY AND
SELL IT  WITHOUT  GOING TO COURT IN A  FORECLOSURE  ACTION  UPON  DEFAULT BY THE
LESSEE UNDER THIS  INSTRUMENT,  and (ii) upon the occurrence of a Lease Event of
Default,  the Lessor,  in lieu of or in addition to exercising any power of sale
hereinabove  given,  may proceed by a suit or suits in equity or at law, whether
for a foreclosure  hereunder,  or for the sale of the  Property,  or against the
Lessee on a recourse  basis for the Asset  Termination  Value,  or the  specific
performance  of any  covenant or  agreement  herein  contained  or in aid of the
execution  of any power herein  granted,  or for the  appointment  of a receiver
pending  any  foreclosure  hereunder  or the  sale of the  Property,  or for the
enforcement  of any other  appropriate  legal or equitable  remedy.  The parties
hereto intend that,  in addition to any other debt or obligation  secured by the
Lien  granted  pursuant to this  Section  17.4,  such Lien shall  secure  unpaid
balances of Rent and  Supplemental  Rent and other  extensions of credit made by
the  Lessor to the  Lessee  after this  Lease is  delivered  to the  appropriate
recording  offices of Colorado,  whether made  pursuant to an  obligation of the
Lessee or otherwise, and such Rent and Supplemental Rent shall be secured to the
same extent as if such future payment  obligations of Rent and Supplemental Rent
were on account of  obligatory  advances to be made under a  construction  loan;
provided such  obligations  secured  hereby at any one time shall not exceed the
lesser of : (i) the maximum principal sum permitted by the laws of Colorado;  or
(ii)  one  hundred  thirty-two  million  Dollars  ($132,000,000)  together  with
interest or Yield thereon  calculated at the rates provided in the Participation
Agreement.

         17.5.  Remedies  Cumulative.  The  remedies  herein  provided  shall be
cumulative  and in addition  to (and not in  limitation  of) any other  remedies
available  at law,  equity or  otherwise,  including,  without  limitation,  any
mortgage foreclosure remedies.

         17.6.  Lessee's Right to Cure.  Notwithstanding any provision contained
in the Lease or any other Operative  Agreement,  if a Lease Event of Default has
occurred and is  continuing,  the Lessee shall have the right to cure such Lease
Event of Default by  exercising  its  Purchase  Option at any time prior to such
time as a foreclosure upon or sale of the Property has been completed.

                                  ARTICLE XVIII

         18.1.  The Lessor's  Right to Cure the  Lessee's  Lease  Defaults.  The
Lessor,  without  waiving or releasing any obligation or Lease Event of Default,
may (but shall be under no  obligation  to)  remedy  any Lease  Default or Lease
Event of Default (other than those described in Sections 7.1(g), (h) and (i))for
the  account  and at the sole cost and  expense  of the  Lessee,  including  the
failure by the Lessee to maintain  the  insurance  required by Article  XIV, and
may, to the fullest extent  permitted by law, and  notwithstanding  any right of
quiet enjoyment in favor of the Lessee, enter upon the Property for such purpose
and take all such action thereon as may be necessary or appropriate therefor. No
such entry shall be deemed an eviction of the Lessee.  All  out-of-pocket  costs
and expenses so incurred (including fees and expenses of counsel), together with
interest  thereon  at the  Overdue  Rate  from the date on  which  such  sums or
expenses  are paid by the  Lessor,  shall be paid by the Lessee to the Lessor on
demand, as Supplemental Rent.


                                   ARTICLE XIX

         19.1.  Provisions Relating to the Lessee's Termination of this Lease or
Exercise of Purchase  Option or Obligation and Conveyance  Upon  Remarketing and
Conveyance Upon Certain Other Events.  (a) In connection with any termination of
this Lease  pursuant to the terms of Article XVI (if the Lessee is  obligated to
purchase the  Property),  or in  connection  with the  Lessee's  exercise of its
Purchase Option, Remarketing Option or Expiration Date Purchase Obligation, upon
the date on which this Lease is to terminate or upon the  Expiration  Date,  and
upon tender by the Lessee of the amounts set forth in Sections 16.2(b), 17.2(h),
20.1, 20.2, 20.3, or 22.1 as applicable, the Lessor shall execute and deliver to
the Lessee (or to the  Lessee's  designee)  at the  Lessee's  cost and expense a
quitclaim  or warranty  deed to the extent  required by local  custom and by the
Lessee's title insurance company to the extent necessary to enable the Lessee to
obtain  customary title  insurance at closing of the Lessor's  right,  title and
interest  in  the  Property  (which  shall  include  a  release,  quitclaim  and
assignment  of all of the Lessor's  right,  title and interest in and to any Net
Proceeds not previously received by the Lessor),  subject to the Permitted Liens
and the  Permitted  Exceptions  (other  than Lessor  Liens) and any  encumbrance
caused by the fault,  neglect or intention of the Lessee, in recordable form and
otherwise in conformity with local custom and free and clear of the Mortgage and
any  Lessor  Liens  attributable  to the  Lessor;  provided  that in the event a
warranty deed is required, the Lessee shall defend,  indemnify and hold harmless
the Lessor from and against any and all Claims relating to title to the Property
other than Lessor Liens. The Improvements and the Equipment shall be conveyed to
the Lessee "AS IS" and in their then  present  condition  of title and  physical
condition.

         (b) If the Lessee properly exercises the Remarketing  Option,  then the
Lessee shall, on the Expiration Date, and at its own cost,  transfer  possession
of the Property to the independent  purchaser thereof,  by surrendering the same
into the  possession of the Lessor or such  purchaser,  as the case may be, free
and clear of all Liens other than Lessor Liens,  in good  condition (as modified
by Modifications  permitted by this Lease),  ordinary wear and tear




                                      -28-

<PAGE>

excepted,  in  compliance  with  Applicable  Law,  and  in  "broom-swept  clean"
condition.  The  Lessee  shall  cooperate  reasonably  with the  Lessor  and the
independent  purchaser  of the Property in order to  facilitate  the purchase by
such  purchaser of the Property which  cooperation  shall include the following,
all of which the Lessee shall do on or before the Expiration Date: providing all
books and records  regarding the  maintenance  and ownership of the Property and
all  know-how,  data and technical  information  relating  thereto,  providing a
current  copy of the "as  built"  Plans  and  Specifications  for the  Property,
granting or assigning all licenses  necessary for the operation and  maintenance
of the  Property  and  cooperating  reasonably  in  seeking  and  obtaining  all
necessary  Governmental  Action.  The  obligations  of  the  Lessee  under  this
paragraph shall survive the expiration or termination of this Lease.


                                   ARTICLE XX

         20.1.  Purchase  Option.  Without  limitation of the Lessee's  purchase
obligation pursuant to Sections 20.2 or 20.3, unless the Lessee shall have given
notice of its intention to exercise the Remarketing  Option and the Lessor shall
have entered into a binding contract to sell the Property, the Lessee shall have
the option  (exercisable  by giving the Lessor  irrevocable  written notice (the
"Purchase  Notice")  of the  Lessee's  election  to  exercise  such  option)  to
purchase,  or to designate a third party to  purchase,  the Property on the date
specified  in such  Purchase  Notice,  which date shall be a Payment  Date.  The
purchase  price  shall be equal to the Asset  Termination  Value  plus all other
amounts  owing in  respect of Rent  (including  Supplemental  Rent)  theretofore
accruing (the "Purchase  Option  Price").  The Lessee shall deliver the Purchase
Notice to the Lessor not less than thirty (30) days prior to the  purchase  date
or as otherwise  provided  pursuant to Section 17.2(h).  If the Lessee exercises
its option to purchase the Property pursuant to this Section 20.1 (the "Purchase
Option"),  the Lessor shall  transfer to the Lessee all of the  Lessor's  right,
title  and  interest  in and to the  Property  as of the date  specified  in the
Purchase Notice upon receipt of the Purchase Option Price and all Rent and other
amounts then due and payable under this Lease and any other Operative  Document,
in accordance with Section 19.l(a). The Lessee may assign the Purchase Option to
a third party  separately  from any  permitted  assignment  by the Lessee of its
rights and  obligations  under  Section  25.1 hereof  without the consent of the
Lessor;  provided  that  the  Lessee  shall  remain  primarily  liable  for  the
performance  of any  such  assignees  in  connection  with the  exercise  of the
Purchase Option in accordance with the provisions of Section 25.1 hereof.

         20.2. Expiration Date Purchase Obligation.  Unless (a) the Lessee shall
have  properly  exercised  the  Purchase  Option  pursuant  to Section  20.1 and
purchased  the Property  pursuant  thereto,  (b) the Lessee shall have  properly
exercised the Remarketing  Option and shall have fulfilled all of the conditions
of clauses (a) through (k) of Section 22.1 hereof and the Lessor shall have sold
its  interest in the  Property  pursuant  thereto,  or (c) the Lessee shall have
properly exercised the Renewal Option pursuant to Section 21.1 and the terms and
conditions  of a Renewal  Term  shall have been  agreed  upon  pursuant  to such
Section, then, subject to the terms, conditions and provisions set forth in this
Article,  and in accordance with the terms of Section 19.1(a),  the Lessee shall
purchase  from the Lessor,  and the Lessor  shall  assign to the




                                      -29-

<PAGE>


Lessee without recourse, on the Expiration Date of the Term (as such Term may be
renewed pursuant to Section 21.1) all of the Lessor's right,  title and interest
in the  Property  (subject to all  existing  Liens,  other than the Mortgage and
Lessor Liens) for an amount equal to the Asset Termination Value. The Lessee may
designate,  in a notice given to the Lessor not less than ten (10) Business Days
prior  to the  closing  of  such  purchase  (time  being  of the  essence),  the
transferee or transferees to whom the conveyance shall be made (if other than to
the  Lessee),  in which case such  conveyance  shall  (subject  to the terms and
conditions set forth herein) be made to such designee;  provided,  however, that
such designation of a transferee or transferees shall not cause the Lessee to be
released,  fully or  partially,  from any of its  obligations  under this Lease,
including,  without limitation, the obligation to pay the Lessor an amount equal
to the Asset  Termination  Value  that was not fully  and  finally  paid by such
designee on such Expiration Date.

         20.3.  Acceleration  of Purchase  Obligation.  (a) The Lessee  shall be
obligated to purchase for an amount equal to the Asset  Termination  Value,  the
Lessor's  interest  in the  Property  (notwithstanding  any  prior  election  to
exercise its Purchase  Option  pursuant to Section 20.1) (i)  automatically  and
without  notice upon the  occurrence of any Lease Event of Default  specified in
clause (f) or (g) of Section 17.1,  and (ii) as provided for at Section  17.2(e)
immediately  upon written  demand of the Lessor upon the occurrence of any other
Lease Event of Default.

         (b) The Lessee  shall be  obligated  to purchase for an amount equal to
the Asset  Termination  Value (plus all other  amounts  owing in respect of Rent
(including  Supplemental Rent) theretofore  accruing),  immediately upon written
demand of the Lessor,  the Lessor's  interest in the Property at any time during
the Term when the  Lessor's  interest in the  Property is  foreclosed  due to an
event  arising out of a violation of the warranty of title  contained in Section
12.1 hereof and the Lessor ceases to have title as contemplated by Section 12.1.

         20.4.  Cash  Collateral.  To the extent the  Depository  Bank holds any
Collateral  pursuant to the Cash  Collateral  Agreement  and if,  under the Cash
Collateral Agreement or any Attachment thereto or Notice thereunder,  the Lessor
is entitled to give notice to the  Depository  Bank to apply such  Collateral to
any of its obligations  hereunder or under the Operative  Documents,  whether in
connection with the exercise of its Purchase Option, any purchase  obligation or
the exercise of its  Remarketing  Option,  the Lessor or the Agent  shall,  upon
receipt of such notice from the Lessee, direct the Depository Bank to apply such
Cash  Collateral to such  obligations of the Lessee to the extent so directed by
the Lessee.

                                   ARTICLE XXI

         21.1.    Renewal.

         (a) Subject to the conditions set forth herein, the Lessee, at any time
after the first  anniversary of the Effective  Date,  shall have the option (the
"Renewal Option") by written 






                                      -30-

<PAGE>



request (the "Renewal  Request") to the Lessor,  each  Participant and the Agent
given not later than 90 days prior to the then Expiration Date to renew the Term
for a one-year period  commencing on the date following the Expiration Date then
in effect.  No later than the date (the "Renewal Response Date") which is thirty
(30) days after such  request has been  delivered  to each of the  Lessor,  each
Participant and the Agent,  the Lessor will notify the Lessee in writing (with a
copy to the Agent)  whether or not it consents to such  Renewal  Request  (which
consent may be granted or denied in its sole  discretion  and may be conditioned
on  receipt  of such  financial  information  or other  documentation  as may be
specified by the Lessor including without limitation a satisfactory appraisal of
the Property), provided that if the Lessor shall fail to notify the Lessee on or
prior to the  Renewal  Response  Date,  it shall be deemed to have  denied  such
Renewal  Request.  The renewal of the Term  contemplated  by any Renewal Request
shall become  effective as of the Expiration Date then in effect on or after the
Renewal  Response Date on which the Lessor shall have  consented to such Renewal
Request; provided that such renewal shall be subject to and conditioned upon the
following:

                  (A) on both the Expiration Date then in effect and the date of
         the  Renewal  Request,  (i) no Lease  Default or Lease Event of Default
         shall  have  occurred  and be  continuing,  and (ii) the Lessor and the
         Agent shall have received a Responsible  Officer's  Certificate  of the
         Lessee as to the matters set forth in clause (i) above,

                  (B) the  Lessee  shall  not  have  exercised  the  Remarketing
         Option, and

                  (C) the Participants  shall have agreed to extend the Maturity
         Date  contemporaneously  therewith  pursuant  to  Section  3.6  of  the
         Participation  Agreement  such that the Renewal Term will expire on the
         same date as the extended Maturity Date.

         (b) The renewal of this Lease shall be on the same terms and conditions
as are set forth in this Lease for the original  Term,  with such  modifications
thereto,  if any, as the parties hereto and to the other Operative Documents may
negotiate  based upon the  current  credit  information  regarding  the  Lessee,
interest rates and such other factors as the Lessor may consider relevant.


                                  ARTICLE XXII

         22.1.  Option to Remarket.  Subject to the  fulfillment  of each of the
conditions set forth in this Section 22.1, the Lessee shall have the option (the
"Remarketing Option") to market for the Lessor and complete the sale of all, but
not less than all, of the Lessor's  interest in the  Property on the  Expiration
Date for the Lessor or in the event the conditions  specified in Section 17.2(h)
have occurred.

         The Lessee's  effective  exercise and  consummation  of the Remarketing
Option  shall  be  subject  to the due  and  timely  fulfillment  of each of the
following provisions as of the dates set forth below.


                                      -31-

<PAGE>



         (a)  Not  later  than  one  hundred  eighty  (180)  days  prior  to the
Expiration  Date,  the Lessee  shall give to the  Lessor  written  notice of the
Lessee's exercise of the Remarketing Option, which exercise shall be irrevocable
(except by delivery of a Purchase Notice and consummation of the exercise of the
Purchase Option prior to the earlier of (i) the Expiration Date or (ii) the date
on which the Lessor enters into a binding contract to sell the Property pursuant
to the exercise of the Remarketing Option).

         (b) The Lessee shall  deliver to the Lessor an  Environmental  Audit of
the Property  together  with its notice of exercise of the  Remarketing  Option.
Such  Environmental  Audit  shall be  prepared  by an  environmental  consultant
selected by the Lessor in the Lessor's  reasonable  discretion and shall contain
conclusions reasonably satisfactory to the Lessor as to the environmental status
of the Property.  If such Environmental  Audit indicates any material exceptions
reasonably requiring remedy or further investigation, the Lessee shall have also
delivered a Phase Two environmental  assessment by such environmental consultant
prior to the  Expiration  Date showing the  completion  of the remedying of such
exceptions in compliance with Applicable Law.

         (c) On the date of the  Lessee's  notice to the Lessor of the  Lessee's
exercise of the Remarketing Option (other than pursuant to Section 17.2(h)),  no
Lease Event of Default or Lease Default shall exist, and thereafter,  no uncured
Lease Event of Default or Lease Default shall exist.

         (d) The Lessee  shall  have  completed  in all  Material  respects  all
Modifications,  restoration and rebuilding of the Property  pursuant to Sections
11.1 and 15.1 (as the case may be) and  shall  have  fulfilled  in all  Material
respects all of the conditions and requirements in connection therewith pursuant
to said  Sections,  in each case by the date on which the  Lessor  receives  the
Lessee's notice of the Lessee's  exercise of the Remarketing  Option (time being
of the  essence),  regardless  of whether the same shall be within the  Lessee's
control. The Lessee shall have also paid the cost of all Modifications commenced
prior to the Expiration Date. The Lessee shall not have been excused pursuant to
Section 13.1 from  complying with any Applicable Law that involved the extension
of the ultimate  imposition  of such  Applicable  Law beyond the last day of the
Term. Any Liens (other than Lessor Liens) on the Property that were contested by
the Lessee shall have been removed before the Expiration Date.

         (e) During the  Marketing  Period,  the Lessee shall,  as  nonexclusive
agent for the Lessor,  use commercially  reasonable efforts to sell the Lessor's
interest in the Property on or prior to the Expiration Date (without diminishing
the Lessee's  obligation to consummate the sale on the Expiration Date) and will
attempt to obtain the highest  purchase price therefor and for not less than the
Fair  Market  Sales  Value.  The  Lessee  will be  responsible  for  hiring  and
compensating  brokers  and making  the  Property  available  for  inspection  by
prospective purchasers. The Lessee shall promptly upon request permit inspection
of the  Property  and any  maintenance  records  relating to the Property by the
Lessor, any Participant and any potential purchasers, and shall otherwise do all
things  necessary  to  sell  and  deliver  possession  of  the  Property  to any
purchaser.  All such  marketing  of the Property  shall be at the Lessee's



                                      -32-

<PAGE>



sole  expense.  The Lessee  shall allow the Lessor and any  potential  qualified
purchaser  reasonable  access to the Property for the purpose of inspecting  the
same.

         (f) The Lessee shall  submit all bids to the Lessor,  the Agent and the
Participants,  and the  Lessor  will have the  right to review  the same and the
right to submit any one or more bids.  All bids  shall be on an  all-cash  basis
unless the Lessor, the Agent and the Participants shall otherwise agree in their
sole  discretion.  The  Lessee  shall  procure  bids  from one or more bona fide
prospective  purchasers  and  shall  deliver  to the  Lessor,  the Agent and the
Participants  not less than  ninety  (90) days  prior to the  Expiration  Date a
binding written unconditional (except as set forth below),  irrevocable offer by
such purchaser or purchasers  offering the highest bid to purchase the Property.
No such  purchaser  shall be the Lessee,  or any  Subsidiary or Affiliate of the
Lessee.  The written offer must specify the Expiration  Date as the closing date
unless the Lessor, the Agent and the Participants shall otherwise agree in their
sole discretion.

         (g) In connection  with any such sale of the Property,  the Lessee will
provide to the purchaser all customary "seller's"  indemnities,  representations
and warranties  regarding title,  absence of Liens (except Lessor Liens) and the
condition of the Property,  as well as such other terms and conditions as may be
negotiated between the Lessee and the purchaser. The Lessee shall have obtained,
at its cost and expense,  all required  governmental and regulatory consents and
approvals and shall have made all filings as required by Applicable Law in order
to carry out and  complete  the  transfer of the  Property  and the Lessor shall
reasonably  cooperate,  at the Lessees's expense, with the Lessee to obtain said
items.  As to the  Lessor,  any such sale  shall be made on an "as is,  with all
faults"  basis without  representation  or warranty by the Lessor other than the
absence of Lessor Liens.  Any agreement as to such sale shall be made subject to
the Lessor's rights under this Section 22.1.

         (h) The Lessee shall pay directly,  and not from the sale proceeds, all
prorations,  credits,  costs and expenses of the sale of the  Property,  whether
incurred by the Lessor or the Lessee, including without limitation,  the cost of
all title insurance, surveys, environmental reports, appraisals, transfer taxes,
the Lessor's and the Agent's reasonable attorneys' fees, the Lessee's attorneys'
fees,  commissions,  escrow fees, recording fees, and all applicable documentary
and other transfer taxes.

         (i) The  Lessee  shall pay to the  Agent on or prior to the  Expiration
Date (or to such other  Person as the Agent shall  notify the Lessee in writing,
or in the case of Supplemental  Rent, to the Person entitled  thereto) an amount
equal to the  Residual  Value  Guarantee  Amount,  plus  all Rent and all  other
amounts under this Lease and the other Operative Documents which have accrued or
will  accrue  prior  to or as of the  Expiration  Date,  in the  type  of  funds
specified in Section 3.4 hereof.


         (j) If the selling  price of the  Property is less than the  difference
between (A) the Asset  Termination  Value minus (B) the Residual Value Guarantee
Amount,  then the Lessee shall have caused to be  delivered  to the Lessor,  the
Agent  and each  Participant  the  appraisal  required  by  Section  13.2 of the
Participation  Agreement  thirty (30) Business Days prior to the




                                      -33-

<PAGE>



Expiration  Date and shall pay to the Agent on or prior to the  Expiration  Date
(or to such other  person as the Agent shall  notify the Lessee in writing)  the
amounts  required  to be paid  pursuant  to  Section  13.2 of the  Participation
Agreement.

         (k) The purchase of the Property shall be consummated on the Expiration
Date  following  the payment by the Lessee  pursuant to  paragraphs  (i) and (j)
above and contemporaneously with the Lessee's surrender of the Property pursuant
to Section 19.1(b) and the gross proceeds (the "Gross  Proceeds") of the sale of
the Property (i.e., without deduction for any marketing, closing or other costs,
prorations  or  commissions)  shall be paid  directly  to the  Agent;  provided,
however,  that if the sum of the Gross Proceeds from such sale plus the Residual
Value  Guarantee  Amount paid by the Lessee  pursuant to paragraph (i) above and
the proceeds of the  collateral  applied  thereto under Section 20.4 exceeds the
Asset  Termination  Value,  then the  excess  shall be paid to the Lessee on the
Expiration Date.

         (l) The Lessee  shall not be entitled to  exercise  or  consummate  the
Remarketing Option if a circumstance that would permit the Lessor to require the
Lessee to repurchase the Property under Section 16.3 exists and is continuing.

         If one or more of the foregoing provisions shall not be fulfilled as of
the date set forth above,  or the Property is not purchased as  aforesaid,  then
the Lessor shall declare by written notice to the Lessee the Remarketing  Option
to be null  and void as to the  Property,  in which  event  all of the  Lessee's
rights under this Section 22.1 shall immediately  terminate and the Lessee shall
be obligated to purchase all of the Lessor's  interest in the Property  pursuant
to Section 20.2 on the  Expiration  Date.  Notwithstanding  the  foregoing,  the
Lessee may at any time during the Marketing  Period exercise its Purchase Option
in accordance with Section 20.2 hereof, provided, that the Lessee shall bear all
costs arising out of or  attributable  to the cessation of remarketing  efforts,
including any costs, expenses,  damages or liability which may be alleged by any
prospective purchaser of the Property.

         Except as expressly set forth  herein,  the Lessee shall have no right,
power or authority to bind the Lessor in  connection  with any proposed  sale of
the Property.

         22.2. Certain  Obligations  Continue.  During the Marketing Period, the
obligation of the Lessee to pay Rent  (including  the  installment of Basic Rent
due on the fifth  anniversary  of the Effective  Date or at the end of a Renewal
Term, or on the Expiration Date, as the case may be) shall continue undiminished
until  payment in full to the Agent of the Gross  Proceeds,  the Residual  Value
Guarantee  Amount,  and all other  amounts due to the Lessor with respect to the
Property  under the Operative  Documents.  The Lessor shall have the right,  but
shall be under no duty,  to solicit  bids,  to inquire  into the  efforts of the
Lessee to obtain bids or  otherwise to take action in  connection  with any such
sale, other than as expressly provided in this Article XXII.

         22.3. Support Obligations.  In the event that the Lessee does not elect
to purchase the  Property on the  Expiration  Date or,  pursuant to the Lessor's
exercise of remedies under Article XVII,  this Lease is  terminated,  the Lessee
shall  provide  the  Lessor,  effective  on the




                                      -34-

<PAGE>

Expiration Date, with (i) all permits,  certificates of occupancy,  governmental
licenses  and  authorizations  necessary to use and operate the Property for its
intended  purposes (to the extent such items are transferable or may be obtained
by the  Lessee on behalf  of  another  party),  (ii) such  easements,  licenses,
rights-of-way  and other rights and  privileges  in the nature of an easement as
are reasonably necessary or desirable in connection with the use, repair, access
to or  maintenance  of the  Property as the Lessor  shall  request,  and (iii) a
services  agreement covering such services as the Lessor may request in order to
use and operate the  Property  for its  intended  purposes at such rates (not in
excess of arm's length fair market  rates) as shall be  acceptable to the Lessor
and the Lessee.  All  assignments,  licenses,  easements,  agreements  and other
deliveries  required  by clauses (i) and (ii) of this  Section  22.3 shall be in
form  satisfactory to the Lessor and shall be fully  assignable  (including both
primary  assignments  and assignments  given in the nature of security)  without
payment of any fee, cost or other charge.


                                  ARTICLE XXIII

         23.1.  Holding  Over.  If the  Lessee  shall for any  reason  remain in
possession of the Property after the  expiration or earlier  termination of this
Lease (unless the Property is conveyed to the Lessee),  such possession shall be
as a tenancy at  sufferance  during which time the Lessee shall  continue to pay
Supplemental  Rent that would be payable by the Lessee  hereunder were the Lease
then in full force and effect and the Lessee shall continue to pay Basic Rent at
an annual rate equal to 110% of the average rate of Basic Rent payable hereunder
during the Term.  Such Basic Rent shall be payable from time to time upon demand
by the Lessor.  During any period of tenancy at  sufferance,  the Lessee  shall,
subject to the second  preceding  sentence,  be obligated to perform and observe
all of the terms,  covenants  and  conditions  of this Lease,  but shall have no
rights  hereunder other than the right, to the extent given by law to tenants at
sufferance, to continue its occupancy and use of the Property. Nothing contained
in this Article XXIII shall constitute the consent,  express or implied,  of the
Lessor to the  holding  over of the  Lessee  after  the  expiration  or  earlier
termination  of this Lease (unless the Property is conveyed to the Lessee),  and
nothing contained herein shall be read or construed to relieve the Lessee of its
obligations to purchase or remarket the Property on the Expiration Date pursuant
to Article XX or Article XXII or as  preventing  the Lessor from  maintaining  a
suit for possession of the Property or exercising any other remedy  available to
the Lessor at law or in equity or hereunder.


                                  ARTICLE XXIV

         24.1. Risk of Loss.  During the Term the risk of loss of or decrease in
the  enjoyment and  beneficial  use of the Property as a result of the damage or
destruction thereof by fire, the elements,  casualties,  thefts,  riots, wars or
otherwise  is  assumed  by the  Lessee,  and the  Lessor  shall  in no  event be
answerable or accountable therefor.

                                   ARTICLE XXV

         25.1.  Subletting and  Assignment.  The Lessee may assign with recourse
this Lease or any of its rights or obligations  hereunder in whole or in part to
any  Person,  in which  case  the  Lessee  shall  guarantee  performance  of the
obligations  of such  assignee  under  this  Lease  by a  guaranty  in form  and
substance reasonably acceptable to the Lessor and the Required Participants. The
Lessee may, without the consent of the Lessor,  sublease the Property or portion
thereof to any Person,  provided,  that no such sublease  shall,  materially and
adversely  affect any of the Lessor's  interests,  rights or remedies  under the
Lease or the Lessor's title to the Property.  No  assignment,  sublease or other
relinquishment  of  possession  of the  Property  shall in any way  discharge or
diminish any of the Lessee's  obligations to the Lessor hereunder and the Lessee
shall remain directly and primarily  liable under this Lease as to the Property,
or portion thereof, so assigned or sublet. Any sublease of the Property shall be
made subject to and  subordinated  to this Lease and to the rights of the Lessor
hereunder,  and shall  expressly  provide for the  surrender of the Property (or
portion  thereof) if, after a Lease Event of Default has occurred,  the Lease is
terminated.  All such subleases  shall  expressly  provide for termination at or
prior  to the  earlier  of the  applicable  Expiration  Date  or  other  date of
termination  of this  Lease  unless  either (x) the Lessee  shall  purchase  the
Property pursuant to Article XX or (y) the Lessor shall have (i) received a true
and correct copy of the relevant  sublease  agreement which shall be in form and
substance,  and on terms and  conditions,  acceptable  to the  Lessor,  and (ii)
received an agreement of the Lessee, in form and substance reasonably acceptable
to the Lessor,  to remain  liable for any  diminution of the market value in the
Property as a consequence of the sublease  between the Expiration  Date or other
date of  termination  of this  Lease and the later  expiration  of the  sublease
agreement.  If requested by the Lessee, the Lessor and the applicable  sublessee
shall,  at  the  Lessee's   expense,   execute  and  deliver  a   subordination,
nondisturbance  and  attornment  agreement  with  respect  to any such  sublease
extending  beyond the Expiration Date or other date of termination of this Lease
in form reasonably  satisfactory to the Lessor, the Lessee and the sublessee. No
assignee or  sublessee  shall be permitted  to engage in any  activities  on the
Property to the extent they are substantially different from those engaged in by
the Lessee without the prior written consent of the Lessor,  which consent shall
not be unreasonably withheld,  except that any Assignee or Sublessee may use the
Property for light  manufacturing,  research and development,  office,  storage,
warehouse  and  related  uses  and for any  other  lawful  use  that is not more
burdensome than Lessee's intended use as administration,  manufacturing,  design
research  and  development  and  warehouse  facilities  so long  as such  use is
permitted by Applicable Law, is approved by Lessor,  which approval shall not be
unreasonably  withheld,  and does not  adversely  affect the  value,  utility or
remaining useful life of the Property.


                                  ARTICLE XXVI

         26.1. Estoppel Certificates. At any time and from time to time upon not
less than  twenty  (20) days'  prior  request  by the Lessor or the Lessee  (the
"Requesting  Party"),  the other party (whichever party shall have received such
request,  the "Certifying Party") shall furnish to the Requesting Party (but not
more than four times per year unless required to satisfy the

                                      -36-

<PAGE>


requirements  of any  sublessees  and  only  to the  extent  that  the  required
information  has been  provided to the  Certifying  Party by the other  party) a
certificate  signed by an  individual  having  the office of vice  president  or
higher in the Certifying  Party  certifying that this Lease is in full force and
effect (or that this Lease is in full force and effect as  modified  and setting
forth the  modifications);  the dates to which the Basic  Rent and  Supplemental
Rent have been paid;  to the best  knowledge of the signer of such  certificate,
whether or not the Requesting  Party is in default under any of its  obligations
hereunder  (and,  if so, the  nature of such  alleged  default);  and such other
matters under this Lease as the  Requesting  Party may reasonably  request.  Any
such certificate  furnished  pursuant to this Article XXVI may be relied upon by
the Requesting  Party, and any existing or prospective  mortgagee,  purchaser or
lender,  and any accountant or auditor,  of, from or to the Requesting Party (or
any Affiliate thereof).

                                  ARTICLE XXVII

         27.1.  Right to  Inspect.  During  the  Term,  the  Lessee  shall  upon
reasonable  notice from the Lessor (except that no notice shall be required if a
Lease Event of Default has occurred and is continuing),  permit the Lessor,  the
Agent and their respective  authorized  representatives  to inspect the Property
during  normal  business  hours,   provided  that  such  inspections  shall  not
unreasonably interfere with the Lessee's business operations at the Property.

         27.2. No Waiver.  No failure by the Lessor or the Lessee to insist upon
the strict  performance  of any term hereof or to exercise  any right,  power or
remedy upon a default hereunder, and no acceptance of full or partial payment of
Rent during the  continuance of any such default,  shall  constitute a waiver of
any such default or of any such term. To the fullest extent permitted by law, no
waiver of any default  shall  affect or alter this  Lease,  and this Lease shall
continue  in full force and effect  with  respect to any other then  existing or
subsequent default.


                                 ARTICLE XXVIII

         28.1. Acceptance of Surrender. No surrender to the Lessor of this Lease
or of all or any portion of any Property or of any part of any thereof or of any
interest  therein  shall be valid or effective  unless agreed to and accepted in
writing  by  the  Lessor  and,  prior  to  the  payment  or  performance  of all
obligations owed to the Participants  under the  Participation  Agreement or the
other Operative Documents and termination of the Participants' Commitments,  the
Agent, and no act by the Lessor or the Agent or any  representative  or agent of
the Lessor or the Agent,  other than a written  acceptance,  shall constitute an
acceptance of any such surrender.


                                  ARTICLE XXIX

         29.1. No Merger of Title.  There shall be no merger of this Lease or of
the leasehold  estate  created hereby by reason of the fact that the same Person
may acquire, own or hold, directly or indirectly,  in whole or in part, (a) this
Lease or the leasehold  estate  created  hereby or any interest in this Lease or
such  leasehold  estate,  or (b) the fee estate in the  Property,  except as may
expressly be stated in a written  instrument  duly executed and delivered by the
appropriate Person.

designate  (provided,  however,  in no event shall  either party be obligated to
notify, in the aggregate,  more than five (5) designees of the other party), and
shall be effective upon receipt or refusal thereof.

                                  ARTICLE XXXI

         31.1.  Miscellaneous.  Anything contained in this Lease to the contrary
notwithstanding,  all claims against and liabilities of the Lessee or the Lessor
arising from events commencing prior to the expiration or earlier termination of
this Lease shall survive such expiration or earlier termination.  If any term or
provision of this Lease or any application  thereof shall be declared invalid or
unenforceable,  the  remainder of this Lease and any other  application  of such
term or provision shall not be affected  thereby.  If any right or option of the
Lessee  provided  in this  Lease,  including  any right or option  described  in
Articles  XV, XVI,  XX, XXI or XXII,  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 of law relating to the vesting
of an interest in or the suspension of the power of alienation of property, then
such right or option shall be exercisable only during the period which shall end
twenty-one  (21)  years  after  the date of death  of the last  survivor  of the
descendants of Franklin D. Roosevelt, the former president of the United States,
Henry Ford, the deceased automobile manufacturer,  and John D. Rockefeller,  the
founder  of the  Standard  Oil  Company,  known  to be  alive on the date of the
execution, acknowledgment and delivery of this Lease.

         31.2.  Amendments  and  Modifications.  Subject  to  the  requirements,
restrictions and conditions set forth in the  Participation  Agreement,  neither
this  Lease,  any Lease  Supplement  nor any  provision  hereof may be  amended,
waived,  discharged  or  terminated  except  by  an  instrument  in  writing  in
recordable  form  signed  by the  Lessor  and the  Lessee.  In the  event of any
conflict  or  inconsistency  between  the  terms  hereof  and the  terms  of the
Participation Agreement, the Participation Agreement shall control.

         31.3.  Successors  and Assigns.  All the terms and  provisions  of this
Lease  shall inure to the  benefit of the  parties  hereto and their  respective
successors and permitted assigns.

         31.4.  Headings  and  Table of  Contents.  The  headings  and  table of
contents in this Lease are for convenience of reference only and shall not limit
or otherwise affect the meaning hereof.

         31.5.  Counterparts.  This  Lease  may be  executed  in any  number  of
counterparts,  each of  which  shall  be an  original,  but all of  which  shall
together constitute one and the same instrument.

         31.6. GOVERNING LAW. THIS LEASE SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED  IN  ACCORDANCE  WITH,  THE LAWS OF THE 


                                      -39-

<PAGE>



STATE OF ILLINOIS,  WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES,  EXCEPT AS TO
MATTERS  RELATING TO THE  CREATION OF THE  LEASEHOLD  ESTATE  HEREUNDER  AND THE
EXERCISE OF RIGHTS AND REMEDIES WITH RESPECT THERETO, WHICH SHALL BE GOVERNED BY
AND  CONSTRUED IN  ACCORDANCE  WITH THE LAW OF THE STATE IN WHICH SUCH ESTATE IS
LOCATED.  WITHOUT LIMITING THE FOREGOING, IN THE EVENT THAT THIS LEASE IS DEEMED
TO CONSTITUTE A FINANCING,  WHICH IS THE  INTENTION OF THE PARTIES,  THE LAWS OF
THE STATE OF ILLINOIS,  WITHOUT  REGARD TO CONFLICTS OF LAWS  PRINCIPLES,  SHALL
GOVERN THE CREATION,  TERMS AND PROVISIONS OF THE INDEBTEDNESS EVIDENCED HEREBY,
BUT THE LIEN CREATED  HEREBY AND THE  ENFORCEMENT OF SAID LIEN SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE IN WHICH SUCH ESTATE IS
LOCATED.

         31.7. Limitations on Recourse. The parties hereto agree that the Lessor
shall have no  personal  liability  whatsoever  to the Lessee or its  respective
successors and assigns for any claim based on or in respect of this Lease or any
of the other  Operative  Documents  or arising in any way from the  transactions
contemplated  hereby or thereby;  provided,  however,  that the Lessor  shall be
liable in its  individual  capacity (a) for its own willful  misconduct or gross
negligence (or negligence in the handling of funds),  (b) for  liabilities  that
may result from the incorrectness of any  representation  or warranty  expressly
made by it in Section 8.1 of the  Participation  Agreement  or (c) for any Taxes
based on or measured by any fees,  commission or compensation received by it for
acting  as  the  Lessor  as  contemplated  by  the  Operative  Documents.  It is
understood and agreed that, except as provided in the preceding proviso: (i) the
Lessor shall have no personal liability under any of the Operative  Documents as
a  result  of  acting  pursuant  to and  consistent  with  any of the  Operative
Documents;  (ii)  all  obligations  of the  Lessor  to  the  Lessee  are  solely
nonrecourse  obligations  except to the extent that it has received payment from
others and are enforceable solely against the Lessor's interest in the Property;
and (iii) all such  personal  liability  of the Lessor is  expressly  waived and
released as a condition of, and as consideration for, the execution and delivery
of the Operative  Documents by the Lessor.  Notwithstanding  anything  contained
herein, the restriction stated in the preceding  provisions of this Section 31.7
shall not apply to  liability of the Lessor  arising  because of a breach of the
Lessor's  obligation to remove Lessor Liens or because of its receiving Advances
and failing to  disburse  Advances to Lessee in  accordance  with the  Operative
Documents,  or  failure  to  disburse  proceeds  from  sale of the  Property  in
accordance with this Lease.

         31.8. Original Lease. The single executed original of this Lease marked
"THIS  COUNTERPART IS THE ORIGINAL  EXECUTED  COUNTERPART" on the signature page
thereof and  containing  the receipt of the Agent  therefor on or following  the
signature page thereof shall be the Original Executed  Counterpart of this Lease
(the "Original Executed Counterpart"). To the extent that this Lease constitutes
chattel  paper,  as such term is defined in the  Uniform  Commercial  Code as in
effect in any applicable jurisdiction, no security interest in this Lease may be
created  through the transfer or  possession of any  counterpart  other than the
Original Executed Counterpart.

         31.9.  Usury  Savings  Clause.  Nothing  continued in this Lease or the
other Operative  Documents shall be deemed to require the payment of interest or
other  charges by the Lessee or any other  Person in excess of the amount  which
may lawfully be charged under any  applicable  usury laws. In the event that the
Lessor or any other  Person shall  collect  moneys under this Lease or any other
Operative Document which are deemed to constitute interest  (including,  without
limitation,  the Basic Rent or  Supplemental  Rent)  which  would  increase  the
effective  interest rate to a rate in excess of that  permitted to be charged by
applicable  law,  all such sums deemed to  constitute  interest in excess of the
legal rate shall, upon such  determination,  at the option of the Person to whom
such payment was made, be returned to the Person making such payment or credited
against other amounts owed by the person making such payment.


                            [signature page follows]

                             LEASE SUPPLEMENT NO. 1
                            (And Memorandum of Lease)

         THIS LEASE  SUPPLEMENT  NO. 1 (And  Memorandum  of Lease)  (this "Lease
Supplement")  dated as of August 22,  1997,  between  Lease Plan North  America,
Inc.,  an Illinois  corporation,  not in its  individual  capacity but solely as
lessor (the  "Lessor"),  and Quantum  Corporation,  a Delaware  corporation,  as
lessee (the "Lessee").

         WHEREAS,  the Lessor is the fee owner of the Land Interest described on
Schedule  1 hereto and wishes to lease the Land  Interest  and all  Improvements
thereon  or  which  may  thereafter  be  constructed  thereon  pursuant  to  the
Construction  Agency Agreement or the Lease to the Lessee (the Land Interest and
such Improvements being collectively called the "Property");

         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual
agreements  herein  contained  and other good and  valuable  consideration,  the
receipt and  sufficiency  of which are hereby  acknowledged,  the parties hereto
agree as follows:

         SECTION 1.  Definitions;  Interpretation.  For  purposes  of this Lease
Supplement, capitalized terms used herein and not otherwise defined herein shall
have the meanings  assigned to them in Appendix 1 to the Master Lease,  dated as
of  August  22,  1997,  between  the  Lessee  and the  Lessor;  and the rules of
interpretation  set forth in  Appendix 1 to the Lease  shall apply to this Lease
Supplement.

         SECTION  2.  The  Property.  Attached  hereto  as  Schedule  I  is  the
description  of a  certain  Land  Interest.  Effective  upon the  execution  and
delivery of this Lease  Supplement  by the Lessor and the Lessee,  the  Property
shall be subject to the terms and provisions of the Lease.  Subject to the terms
and conditions of the Lease, the Lessor hereby leases to the Lessee for the Term
(as defined below) of the Lease, the Lessor's interest in the Property,  and the
Lessee hereby agrees,  expressly for the direct benefit of the Lessor,  to lease
from the Lessor for the Term, the Lessor's interest in the Property.

         SECTION 3. Parties and  Addresses.  The Lease is dated as of August 22,
1997,  between the Lessor,  whose principal  office is at 135 S. LaSalle Street,
Chicago,  Illinois 60603 and the Lessee,  whose principal office is 500 McCarthy
Boulevard, Milpitas, California 95305.

<PAGE>



         SECTION 4. Lease Term.  The term of this Lease (the "Term") shall begin
on August 22, 1997, and shall end on August 22, 2002, unless the Term is renewed
or earlier  terminated in accordance with the provisions of the Lease. The Lease
contains option periods of one year each,  which give Lessee the right,  subject
to the terms thereof, to extend the term of the Lease.

         SECTION  5.  Ownership  of the  Property.  (a) It is the  intent of the
parties hereto that: (i) the Lease  constitutes an "operating lease" pursuant to
Statement of Financial  Accounting Standards No. 13, as amended, for purposes of
Lessee's financial reporting,  and (ii) for purposes of Federal and state income
tax,  the  transaction  contemplated  hereby  and by the  Lease  is a  financing
arrangement and preserves ownership in the Property in the Lessee. Nevertheless,
the Lessee  acknowledges  and agrees that neither the Agent,  the Lessor nor any
Participant has made any  representations or warranties to the Lessee concerning
the tax, accounting or legal characteristics of the Operative Documents and that
the Lessee has  obtained and relied upon such tax,  accounting  and legal advice
concerning the Operative  Documents as it deems  appropriate.  Accordingly,  and
notwithstanding any provision of this Lease to the contrary,  the Lessor and the
Lessee agree and declare  that:  (i) the  transactions  contemplated  hereby are
intended to have a dual, rather than a single,  form; and (ii) all references in
this Lease to the "lease" of the Property which fail to reference such dual form
do so as a matter  of  convenience  only and do not  reflect  the  intent of the
Lessor and the Lessee as to the true form of such arrangements.

         (b)   Anything   to   the   contrary   in   the   Operative   Documents
notwithstanding, the Lessor and the Lessee intend and agree that with respect to
the  nature of the  transactions  evidenced  by the Lease in the  context of the
exercise  of  remedies  under  the  Operative  Documents,   including,   without
limitation,  in the case of any  insolvency  or  receivership  proceedings  or a
petition  under  the  United  States  bankruptcy  laws or any  other  applicable
insolvency  laws or  statute  of the  United  States of  America or any State or
Commonwealth  thereof affecting the Lessee, the Lessor or any Participant or any
enforcement or collection actions,  (i) the transactions  evidenced by the Lease
are loans made by the Lessor  and the  Participants  as  unrelated  third  party
lenders  to the Lessee  secured by the  Property,  (ii) the  obligations  of the
Lessee  under  the  Lease  to pay  Basic  Rent  and  Supplemental  Rent or Asset
Termination  Value in connection  with any purchase of the Property  pursuant to
the Lease  shall be  treated  as  payments  of  interest  on and  principal  of,
respectively,  loans from the Lessor and the  Participants  to the  Lessee,  and
(iii) the Lease  grants a security  interest  and  mortgage  or deed of trust or
lien,  as the case may be, in the Property and the  collateral  described in the
Mortgage to the Lessor,  the Agent and the  Participants  to secure the Lessee's
performance  under  and  payment  of all  amounts  under the Lease and the other
Operative Documents.

         (c) Specifically, but without limiting the generality of subsection (b)
of this Section 5, the Lessor and the Lessee  further intend and agree that, for
the  purpose of securing  the  Lessee's  obligations  for the  repayment  of the
above-described  loans from the  Certificate  Purchaser  and the  Lenders to the
Lessee,  (i) the  Lease  shall  also be deemed to be a  security  agreement  and
financing  statement  within the meaning of Article 9 of the Uniform  Commercial
Code and a real property mortgage or deed of trust; (ii) the conveyance provided
for hereby  and in Article II of the Lease  shall be deemed to be a grant by the
Lessee to the  Lessor,  the Agent




                                       -2-

<PAGE>


and the  Participants  of a mortgage  lien and  security  interest in all of the
Lessee's  right,  title and interest in and to the  Property and the  collateral
described  in the  Mortgage  and all  proceeds of the  conversion,  voluntary or
involuntary,  of the  foregoing  into  cash,  investments,  securities  or other
property, whether in the form of cash, investments, securities or other property
(it being  understood that the Lessee hereby mortgages and warrants and grants a
security  interest in the Property and the collateral  described in the Mortgage
to the Lessor,  the Agent and the  Participants to secure the loans);  (iii) the
possession  by the Lessor or any of its agents of notes and such other  items of
property as constitute instruments, money, negotiable documents or chattel paper
shall be  deemed  to be  "possession  by the  secured  party"  for  purposes  of
perfecting  the  security  interest  pursuant  to Section  9-305 of the  Uniform
Commercial Code; and (iv)  notifications  to Persons holding such property,  and
acknowledgments,   receipts  or  confirmations  from  financial  intermediaries,
bankers or agents  (as  applicable)  of the Lessee  shall be deemed to have been
given for the purpose of perfecting such security interest under Applicable Law.
The Lessor and the Lessee shall, to the extent  consistent with the Lease,  take
such  actions  and  execute,  deliver,  file and record  such  other  documents,
financing statements, mortgages and deeds of trust as may be necessary to ensure
that,  if the Lease and this Lease  Supplement  were deemed to create a security
interest in the Property in accordance with this Section, such security interest
would be deemed to be a  perfected  security  interest of first  priority  under
Applicable Law and will be maintained as such throughout the Term.

         (d) Specifically, without limiting the generality of anything contained
in this Section 5, the Lessor and the Lessee  further intend and agree that, for
purposes  of  filing  federal,  state  and  local  returns,  reports  and  other
statements  relating to income or franchise  taxes,  or any other taxes  imposed
upon or  measured  by  income,  (i) the  Lessee  shall be  entitled  to take any
deduction,  credit,  allowance or other reporting  position  consistent with its
status  as  owner  of  the  Property;  and  (ii)  neither  the  Lessor  nor  the
Participants shall take a position on their respective federal,  state and local
returns, reports and other statements relating to income or franchise taxes that
is inconsistent with the Lessee's status as owner of the Property, provided that
the Lessor and any Participant may take a position that is inconsistent with the
Lessee's  status as owner of the Property if: (x) there has been a change in law
or  regulation  so requiring  as  supported by an opinion of counsel  reasonably
acceptable  to the Lessee  that there is not  substantial  authority  for such a
consistent  reporting  position;  or (y) (A) there has been an administrative or
judicial  holding  that the Lessee is not the owner of the Property for such tax
purposes,  (B) the Lessee  has no right to  contest  such  holding  pursuant  to
Section 13.5 of the Participation  Agreement, and (C) the Lessee's lack of right
to  contest  is not  the  result  of an  Indemnitee's  waiver  of its  right  to
indemnification  pursuant to Section 13.5(f)(iii) of the Participation Agreement
or  failure of the  amount at issue to exceed  the  minimum  amount set forth in
Section 13.5(f)(iv)(B) of the Participation Agreement.

         SECTION 6. Remedies.  Without  limiting any other remedies set forth in
the Lease,  in the event that a court of competent  jurisdiction  rules that the
Lease constitutes a mortgage, deed or trust or other secured financing as is the
intent of the parties,  then the Lessor and the Lessee agree that (i) the Lessee
hereby grants a Lien against the Property WITH POWER OF SALE,  and that upon the
occurrence  of a Lease  Event of  Default,  the Lessor  shall have the power and
authority,  to the extent provided by law, after proper notice and lapse of such
time as may be 




                                       -3-

<PAGE>


required by law, to sell the Property at the time and place of sale fixed by the
Lessor in said notice of sale, either as a whole, or in separate lots or parcels
or items and in such order as the Lessor  may elect,  at auction to the  highest
bidder  for cash in lawful  money of the  United  States  payable at the time of
sale;  accordingly,  it is acknowledged that A POWER OF SALE HAS BEEN GRANTED IN
THIS  INSTRUMENT;  A POWER OF SALE MAY ALLOW THE LESSOR TO TAKE THE PROPERTY AND
SELL IT  WITHOUT  GOING TO COURT IN A  FORECLOSURE  ACTION  UPON  DEFAULT BY THE
LESSEE UNDER THIS  INSTRUMENT,  and (ii) upon the occurrence of a Lease Event of
Default,  the Lessor,  in lieu of or in addition to exercising any power of sale
hereinabove  given,  may proceed by a suit or suits in equity or at law, whether
for a foreclosure  hereunder,  or for the sale of the  Property,  or against the
Lessee on a recourse basis for the Asset Termination  Value, or for the specific
performance  of any  covenant or  agreement  herein  contained  or in aid of the
execution  of any power herein  granted,  or for the  appointment  of a receiver
pending  any  foreclosure  hereunder  or the  sale of the  Property,  or for the
enforcement  of any other  appropriate  legal or equitable  remedy.  The parties
hereto intend that,  in addition to any other debt or obligation  secured by the
Lien granted  pursuant to this Section 6, such Lien shall secure unpaid balances
of Rent and Supplemental  Rent and other extensions of credit made by the Lessor
to the Lessee after this Lease is delivered to the appropriate recording offices
of Colorado,  whether made pursuant to an obligation of the Lessee or otherwise,
and such Rent and  Supplemental  Rent shall be secured to the same  extent as if
such future payment obligations of Rent and Supplemental Rent were on account of
obligatory  advances  to be  made  under  a  construction  loan;  provided  such
obligations  secured hereby at any one time shall not exceed the lesser of : (i)
the  maximum  principal  sum  permitted  by the laws of  Colorado;  or (ii) [one
hundred  thirty-two  million dollars  ($132,000,000)]  together with interest or
Yield thereon calculated at the rates provided in the Participation Agreement.

         SECTION 7. Purchase Option.  Sections  17.2(h),  19 and 20 of the Lease
contain  various  purchase  options  which may be exercised by Lessee during the
term of the Lease subject to the terms and conditions of said Sections 19 and 20
of the Lease.

         SECTION  8.  Liens.  (a) THIS LEASE IS  SUPERIOR  TO A DEED OF TRUST IN
FAVOR OF ABN AMRO BANK N.V., SAN FRANCISCO  INTERNATIONAL  BRANCH, AS AGENT (THE
"AGENT") UNDER THE PARTICIPATION  AGREEMENT,  DATED AS OF AUGUST 22, 1997, AMONG
THE LESSEE,  THE LESSOR,  THE AGENT AND THE  PARTICIPANTS,  EXCEPT AS AMENDED OR
SUPPLEMENTED.

         (b) NOTICE IS HEREBY GIVEN THAT NEITHER THE LESSOR, ANY PARTICIPANT NOR
THE AGENT IS OR SHALL BE LIABLE FOR ANY LABOR,  SERVICES OR MATERIALS  FURNISHED
OR TO BE FURNISHED TO THE LESSEE,  OR TO ANYONE HOLDING THE PROPERTY OR ANY PART
THEREOF THROUGH OR UNDER THE LESSEE,  AND THAT NO MECHANICS'S OR OTHER LIENS FOR
ANY SUCH LABOR,  SERVICES OR MATERIALS SHALL ATTACH TO OR AFFECT THE INTEREST OF
THE LESSOR IN AND TO THE PROPERTY.

         SECTION 9.  Ratification.  Except as specifically  modified hereby, the
terms and  provisions of the Lease are hereby  ratified and confirmed and remain
in full force and effect.

         SECTION 10. Original Lease Supplement.  The single executed original of
this  Lease  Supplement  marked  "THIS  COUNTERPART  IS  THE  ORIGINAL  EXECUTED
COUNTERPART"  on the signature  page thereof and  containing  the receipt of the
Agent  therefor on or following the signature page thereof shall be the Original
Executed   Counterpart  of  this  Lease   Supplement  (the  "Original   Executed
Counterpart").  To the extent  that this Lease  Supplement  constitutes  chattel
paper,  as such term is defined in the Uniform  Commercial  Code as in effect in
any applicable  jurisdiction,  no security interest in this Lease Supplement may
be created through the transfer or possession of any counterpart  other than the
Original Executed Counterpart.

         SECTION  11.  GOVERNING  LAW.  THE  LEASE  SHALL BE  GOVERNED  BY,  AND
CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF ILLINOIS,
WITHOUT REGARD TO CONFLICTS OF LAW PRINCIPLES,  EXCEPT AS TO MATTERS RELATING TO
THE CREATION OF THE LEASEHOLD  ESTATE  THEREUNDER AND THE EXERCISE OF RIGHTS AND
REMEDIES  WITH  RESPECT  THERETO,  WHICH SHALL BE GOVERNED BY AND  CONSTRUED  IN
ACCORDANCE  WITH THE LAW OF THE STATE IN WHICH THE  ESTATE IS  LOCATED.  WITHOUT
LIMITING THE  FOREGOING,  IN THE EVENT THAT THE LEASE IS DEEMED TO  CONSTITUTE A
FINANCING,  WHICH IS THE  INTENTION  OF THE  PARTIES,  THE LAWS OF THE  STATE OF
ILLINOIS,  WITHOUT  REGARD TO  CONFLICTS  OF LAWS  PRINCIPLES,  SHALL GOVERN THE
CREATION,  TERMS AND PROVISIONS OF THE INDEBTEDNESS  EVIDENCED  HEREBY,  BUT THE
LIEN CREATED  HEREBY AND THE  ENFORCEMENT  OF SAID LIEN SHALL BE GOVERNED BY AND
CONSTRUED  IN  ACCORDANCE  WITH  THE LAW OF THE  STATE IN WHICH  THE  ESTATE  IS
LOCATED.

         SECTION  12.  Counterpart  Execution.  This  Lease  Supplement  may  be
executed  in any number of  counterparts  and by each of the  parties  hereto in
separate  counterparts,  all such counterparts together constituting but one and
the same instrument.

Advance (other than an Interest Payment Advance) shall be in a minimum amount of
$1,000,000  or in  amounts  of  $100,000  in  excess  thereof.  Subject  to  the

Commitment,   Tranche  B  Participation   Interest   Commitment  and  Tranche  C
Participation  Interest  Commitment)  allocated to the Two Year Commitment,  and
(vi) the  percentage  referred to in the  definition of the term  "Participation
Interest".  The Lessee,  the Lessor and the Participants  have approved all such
allocations and percentages.  Schedule I shall be amended as required to reflect
changes in the  allocations  set forth thereon due to the addition of additional
Participants pursuant to Section 12.1.

         SECTION 3.6 Use of Commitments. (a) All remittances by each Participant
to the  Lessor  to  fund  Advances  shall  be  allocated  first,  to the 364 Day
Commitment of such  Participant,  and second, to the Two Year Commitment of such
Participant.  Unless  extended  as  provided in this  Section  3.6,  the 364 Day
Commitment shall terminate on the day which is 364 days after the Effective Date
and the unused portion thereof shall not be available to the Lessor  thereafter.
The Lessee shall notify the Lessor, the Agent and each Participant not less than
forty-five  (45) days  prior to the  expiration  date of the 364 Day  Commitment
whether it wishes to extend the  availability  of the unused  portion of the 364
Day Commitment to the Six Month Extension  Termination Date. The availability of
the unused  portion of the 364 Day Commitment  shall not be extended  unless the
Agent and each  Participant,  in its sole  discretion,  has  notified the Lessor
within fifteen (15) days prior to such  termination date that it will permit the
unused  portion  of its 364  Day  Commitment  to be  extended  to the Six  Month
Extension  Termination Date commencing on the Extension Date. The Agent and each
Participant may make such decision based upon such credit information  regarding
the Lessee,  interest  rates,  market  conditions  and such other factors as the
Agent and such  Participant may consider  relevant.  The Lessor shall notify the
Lessee  whether  the  Agent and the  Participants  have  agreed  to  permit  the
extension  of such  unused  portion of the 364 Day  Commitment  to the Six Month
Extension  Termination  Date.  Any  portion  that  is  so  extended  shall  bear
Commitment  Fees from and after the Extension  Date at a rate  applicable to the
364 Day  Commitment.  The  parties  hereto  shall  amend  Schedule  I hereto  in
connection  with any such extension.  The Lessee shall have the right,  upon not
less than three Business  Days' written  notice to the Agent,  to reduce the 364
Day  Commitment  and/or the Two Year  Commitment;  provided,  that after  giving
effect to such  notification,  the aggregate  outstanding amount of the Advances
shall not exceed the aggregate Commitments as so reduced.

                  (b) If the 364 Day Commitment is extended  pursuant to Section
3.6(a),  the  Lessee  shall pay to each  Participant  its pro rata  share of the
Extension Fee on the Extension Date.

         SECTION  3.7  Termination,  Extension  or  Reduction  of  Participants'
Commitments.  (a) The  Lessor  shall  have the  right,  upon not less than three
Business  Days'  written  notice to the Agent,  to terminate  the  Participants'
Commitments  or,  from time to time,  to reduce the amount of the  Participants'
Commitments,  provided  that (i)  after  giving  effect to such  reduction,  the
aggregate outstanding principal amount of the Tranche A Participation  Interests
shall not exceed the aggregate  Tranche A  Participation  Interest  Commitments,
(ii) after giving effect to such reduction,  the aggregate outstanding principal
amount of the Tranche B  Participation  Interests shall not exceed the aggregate
Tranche B Participation Interest Commitments,  (iii) after giving affect to such
reduction,  the  aggregate  outstanding  equity  investment  of  the  Tranche  C
Participation  Interests shall not exceed the aggregate  Tranche C Participation
Interest  Commitments,  and (iv) any such reduction shall be made pro rata among
the Participants' Commitments within each Tranche. As long as there


                                       -4-

exists no Event of Default that has occurred and is continuing, the Lessor shall
exercise such right only as directed by the Lessee, and after the occurrence and
during the  continuance  of an Event of Default the Lessor shall  exercise  such
right only as directed by the Required  Participants.  In the event that,  after
the occurrence and during the continuance of an Event of Default, the Lessor and
the  Participants  exercise  such right,  the Lessee may  exercise  its Purchase
Option under Section 20.1 of the Lease upon not less than ten (10) days' written
notice to the Lessor.

                  (b) The Lessee may, at any time after the first anniversary of
the Effective  Date, by written request to the Lessor and Agent (which the Agent
shall promptly forward to each  Participant)  given not later than 90 days prior
to the then current  Maturity Date,  request (an  "Extension  Request") that the
Maturity  Date be extended to the date that is one (1) year after such  Maturity
Date. No later than the date (the  "Extension  Response  Date") which is 30 days
after  such  request  has  been  delivered  to  each of the  Participants,  each
Participant  will notify the Lessor in writing (with a copy to the Agent and the
Lessee) whether or not it consents to such Extension  Request (which consent may
be  granted  or denied by each  Participant  in its sole  discretion  and may be
conditioned on receipt of such financial  information or other  documentation as
may be specified by such Participant  including without limitation  satisfactory
appraisals  of the  Property),  provided that any  Participant  that fails to so
advise the Lessor on or prior to the Extension  Response Date shall be deemed to
have  denied  such  Extension  Request.  The  extension  of  the  Maturity  Date
contemplated by any Extension  Request shall become effective as of the Maturity
Date then in effect (the "Extension  Effective  Date") on or after the Extension
Response  Date on  which  all of the  Participants  (other  than  Non-Consenting
Participants which have been replaced by Replacement  Participants in accordance
with Section  3.7(c)) shall have consented to such Extension  Request;  provided
that:

                           (A) on both the date of the Extension Request and the
         Extension   Effective  Date,  (x)  each  of  the   representations  and
         warranties  made by the  Lessee and the  Lessor in or  pursuant  to the
         Operative  Documents shall be true and correct in all material respects
         as if made on and as of each such date, except for  representations and
         warranties made as of a specific date,  which shall be true and correct
         in all  material  respects  as of such date and  matters  waived by the
         Required Participants or all of the Participants, as applicable, (y) no
         Event of Default shall have occurred and be continuing, and (z) on each
         of such dates the Agent shall have received a certificate of the Lessee
         and the  Lessor,  each as to  itself,  as to the  matters  set forth in
         clause  (x) above and from the  Lessee as to the  matters  set forth in
         clause (y) above;

                           (B) on the date that is 90 days  prior to the date of
         the  Extension  Effective  Date  that is the fifth  anniversary  of the
         Closing Date (and on each  Extension  Effective  Date,  if any, that is
         every fifth  anniversary  thereafter),  the Lessee shall deliver to the
         Lessor and the Agent (with sufficient  copies for each  Participant) an
         Appraisal of the  Property in form and  substance  satisfactory  to the
         Lessor and the Agent; and

                           (C) the Agent  and the  Required  Participants  shall
         have received  satisfactory  evidence that the  Expiration  Date shall,
         after giving effect to any extension thereof which 

                                       -5-

<PAGE>


         has become  effective  on or prior to such  Extension  Effective  Date,
         occur on the Maturity Date as so extended.

                  (c)  The   Lessee   shall  be   permitted   to   replace   any
Non-Consenting   Participant   with  a  replacement   bank  or  other  financial
institution (a  "Replacement  Participant")  at any time on or prior to the date
which is 30 days after the relevant Extension  Response Date;  provided that (i)
such  replacement  does not  conflict  with  any  Requirement  of Law,  (ii) the
Replacement  Participant  shall  purchase,  at  par,  all of  the  Participation
Interest  of  such  Non-Consenting  Participant  on or  prior  to  the  date  of
replacement, (iii) the Lessee shall be liable to such Non-Consenting Participant
under  Section 13 of this  Agreement if any Advance (or  Participation  Interest
therein)  shall be  prepaid  (or  purchased)  other  than on the last day of the
Interest  Period or Interest  Periods  relating  thereto,  (iv) the  Replacement
Participant,  if not already a Participant,  shall be reasonably satisfactory to
the Required Participants, (v) such replacement shall be made in accordance with
the  provisions  of Section 12 of this  Agreement  (provided  that the  relevant
Replacement  Participant  (or the  Lessee for the  benefit  of such  Replacement
Participant)  shall be  obligated  to pay the  Transaction  Expenses  arising in
connection therewith),  (vi) the Replacement Participant shall have agreed to be
subject to all of the terms and  conditions  of this  Agreement  (including  the
extension of the Maturity Date contemplated by the relevant  Extension  Request)
and other Operative Documents,  and (vii) during the continuation of an Event of
Default,  the Lessee shall have the exclusive right to designate the Replacement
Participant.  The  Agent  hereby  agrees  to  cooperate  with the  Lessee in the
Lessee's efforts to arrange one or more Replacement Participants as contemplated
by this Section 3.7(c).

         SECTION 3.8 Interest Rates;  Yield and Payment Dates. (a) The Tranche A
Participation  Interest and the Tranche B Participation Interest in each Advance
shall bear interest at a rate of interest  equal to (i) the Alternate Base Rate,
or (ii) at the Lessee's  election in accordance with Section 3.4 or this Section
3.8, for each day during each Interest Period with respect thereto at a rate per
annum for such Interest  Period equal to the Eurodollar Rate determined for such
day plus the Applicable  Margin.  The Tranche A  Participation  Interest and the
Tranche B Participation Interest in the initial Advance shall bear interest at a
rate equal to the Alternate Base Rate until commencement of the initial Interest
Period with respect  thereto.  The Lessee shall give  irrevocable  notice to the
Agent,  in  accordance  with the  applicable  provisions  of Section 3.4 or this
Section  3.8, of the length of each  Interest  Period to be  applicable  to each
portion of each Advance.  There shall not be more than twelve  Interest  Periods
outstanding under Sections 3.8(a) and (b) at any time.
 
                  (b) The equity  portion of each  Advance  (represented  by the
Tranche C Participation Interest in such Advance) shall accrue equity yield (the
"Yield") at a rate equal to (i) the Alternate Base Rate, or (ii) at the Lessee's
election in accordance with Section 3.4 or this Section 3.8, for each day during
each Interest  Period with respect  thereto,  the Eurodollar Rate determined for
such day plus the Applicable  Margin.  This Tranche C Participation  Interest in
the initial  Advance  shall accrue Yield at a rate equal to the  Alternate  Base
Rate until commencement of the initial Interest Period with respect thereto.

                  (c) If all or a portion of (i) the principal  amount or equity
portion of any Advance,  (ii) any interest or Yield payable thereon or (iii) any
other amount payable hereunder shall not be 

                                      -6-
<PAGE>

paid when due (whether at the stated  maturity,  by  acceleration or otherwise),
such overdue  amount  shall bear  interest at a rate per annum which is equal to
the Overdue Rate.

                  (d)  Interest  and Yield  shall be payable in cash  (except as
provided in  paragraph  (e) below) in arrears on each  Scheduled  Payment  Date,
provided that (i) interest or Yield  accruing  pursuant to paragraph (c) of this
Section  3.8  shall  be  payable  from  time to time on  demand  and  (ii)  each
prepayment of Advances shall be accompanied by accrued interest and Yield to the
date of such prepayment on the amount of Advances so prepaid.

                  (e) On each date  which is three  Business  Days  prior to any
Scheduled  Payment  Date during the  Construction  Period,  the Lessee  shall be
deemed to have  requested an Advance  comprised of an Interest  Payment  Advance
pursuant  to Section  3.4 and the  Lessor  shall be deemed to have  requested  a
purchase  pursuant to Section 3.2 of Participation  Interests in such Advance in
an amount  equal to the  aggregate  amount of the Basic Rent due and  payable on
such date with  respect to accrued  interest  and accrued  Yield on  outstanding
Advances. The Funding Date with respect to any such Interest Payment Advance and
purchase of  Participation  Interests  therein  shall be the relevant  Scheduled
Payment Date (provided that such Advance and the purchase of such  Participation
Interests  shall  be  subject  to  satisfaction  of  the  applicable  conditions
precedent  set forth in Section 6) and the  proceeds  of such  payment  shall be
applied to pay such  accrued  interest and accrued  Yield.  On each such Funding
Date,  the Property Cost shall be increased by an amount equal to the Basic Rent
paid on such  date with  respect  to such  Property  with the  proceeds  of such
payment, and the Land Interest Acquisition Cost and Property  Improvements Costs
shall be increased by their pro rata portions of such Advance.

         SECTION 3.9  Computation  of  Interest  and Yield.  (a)  Whenever it is
calculated on the basis of the Alternate Base Rate,  interest and Yield shall be
calculated on the basis of a 365- (or 366-, as the case may be) day year for the
actual days elapsed;  and, otherwise,  interest and Yield shall be calculated on
the basis of a 360-day year for the actual days elapsed. The Agent shall as soon
as practicable after the commencement of each Interest Period notify the Lessor,
the Lessee and the Participants of each  determination of a Eurodollar Rate. Any
change in the interest rate or Yield rate on an Advance  resulting from a change
in the Alternate Base Rate or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change  becomes
effective.  The Agent shall as soon as practicable notify the Lessor, the Lessee
and the Participants of the effective date and the amount of each such change in
interest rate or Yield rate.

                  (b) Each  determination  of an interest  rate or Yield rate by
the Agent  pursuant to any provision of this  Agreement  shall be conclusive and
binding  on the  Lessor,  the  Lessee  and the  Participants  in the  absence of
manifest error. The Agent shall, at the request of such parties, deliver to such
parties a statement  showing the quotations used by the Agent in determining any
interest rate pursuant to Section 3.9(a).

         SECTION 3.10 Pro Rata Treatment and Payments. (a) Each participation in
the Advances by the Participants hereunder and each reduction of the Commitments
of the  Participants  shall be made pro rata among the  Tranche A  Participants,
Tranche B Participants  and Tranche C  Participants  according to the respective
Commitment Percentages of each such Participant. Except as otherwise


                                      -7-
<PAGE>

provided in Sections 3.11 - 3.21, each payment  (including  each  prepayment) by
the Lessor on account of  Participation  Interests  representing  the  principal
amount of or equity investment in and interest or Yield on the Advances shall be
made pro rata  among the  Tranche A  Participants,  Tranche B  Participants  and
Tranche C Participants  according to the respective  Participation  Interests of
each such Participant.  All payments  (including  prepayments) to be made by the
Lessor  hereunder  to the  Participants  with  respect  to  their  Participation
Interests,  whether on account of principal, equity investment,  interest, Yield
or otherwise,  shall be payable to the extent  received by the Lessor from or on
behalf of the Lessee and shall be made without setoff or counterclaim  and shall
be made prior to 12:00 noon, San Francisco  time, on the due date thereof to the
Agent, for the account of the Participants, at the Agent's office referred to in
Section 15.3 of this Agreement,  in Dollars and in immediately  available funds.
The Agent shall  distribute  such  payments to the  Participants  promptly  upon
receipt in like funds as received. If any payment hereunder (other than payments
of  Participation  Interests in the  Advances)  becomes due and payable on a day
other than a Business Day, such payment shall be extended to the next succeeding
Business Day. If any payment of  Participation  Interests in an Advance  becomes
due and payable on a day other than a Business  Day, the maturity  thereof shall
be  extended  to the next  succeeding  Business  Day  unless  the result of such
extension would be to extend such payment into another  calendar month, in which
event such payment shall be made on the immediately  preceding  Business Day. In
the case of any extension or shortening of the due date of any payment  pursuant
to the  preceding two  sentences,  interest or Yield thereon shall be payable at
the then applicable rate during such extension or until such shortened due date,
as the case may be.

         (b)  Unless  the Agent  shall  have been  notified  in  writing  by any
Participant prior to funding its Participation  Interest in an Advance that such
Participant will not make its share of such Advance  available to the Agent, the
Agent may assume that such  Participant  is making such amount  available to the
Agent,  and the Agent may, in reliance upon such  assumption,  make available to
the Lessor a corresponding  amount.  If such amount is not made available to the
Agent by the  required  time on the Funding  Date  therefor,  such  Participant,
without right of reimbursement from the Lessee to such Participant, shall pay to
the Agent, on demand,  such amount with interest  thereon at a rate equal to the
daily average Federal Funds Effective Rate for the period until such Participant
makes such amount immediately available to the Agent. A certificate of the Agent
submitted  to any  Participant  with  respect to any  amounts  owing  under this
Section  3.10(b) shall be conclusive in the absence of manifest  error.  If such
Participant's  share of such Advance is not made  available to the Agent by such
Participant  within three  Business Days of such Funding  Date,  the Agent shall
also be entitled to recover such amount with interest  thereon at the rate borne
by such Advance,  on demand, from the Lessee, to the extent the Agent has made a
corresponding amount of the Advance to the Lessee.

         SECTION 3.11 The Account.  The Agent may if it so desires  establish an
account  (the  "Account")  into  which the Agent  shall  deposit  all  payments,
receipts and other consideration of any kind whatsoever paid under the Lease and
received  by the  Agent  pursuant  to this  Agreement,  the  Lease and any other
Operative  Document.  The  Agent  shall  make  distributions  of such  payments,
receipts and other  consideration (and, if an Account is used, from the Account)
pursuant to the requirements of Sections 3.12 -3.21 hereof.

                                      -8-

         SECTION 3.12 Basic Rent. (a) Each payment (or portion thereof) of Basic
Rent  comprising  interest or Yield on the Advances (and any payment of interest
on overdue  installments  of such component of Basic Rent) received by the Agent
shall be distributed  by the Agent as promptly as possible (it being  understood
that any  payments of such  component  of Basic Rent  received by the Agent on a
timely  basis  and in  accordance  with the  provisions  of the  Lease  shall be
distributed  on the date received in the funds so received) to the  Participants
pro rata in  accordance  with,  and for  application  to,  the  portion of their
Participation Interests in such portion of Basic Rent, as well as in any overdue
interest due to such Participant (to the extent permitted by applicable law).

                  (b) Each payment (or portion thereof) of Basic Rent comprising
principal of, or a redemption of the equity investment in, the Advances (and any
payment of interest on overdue  installments  of such  component  of Basic Rent)
received by the Agent  shall be  distributed  as promptly as possible  (it being
understood  that any payments of such  component  of Basic Rent  received by the
Agent on a timely basis and in accordance with the provisions of the Lease shall
be  distributed  on  the  date  received  in  the  funds  so  received)  to  the
Participants pro rata in accordance with, and for application to, the portion of
their  Participation  Interests  in such  portion  of Basic  Rent  then due each
Participant.

         SECTION  3.13  Purchase  Payments by Lessee.  Any payment  received (or
offset against the Cash Collateral) by the Agent as a result of:

                  (a) the purchase of the  Lessor's  interest in the Property in
         connection  with the  Lessee's  exercise of its  Purchase  Option under
         Section 20.1 of the Lease, or

                  (b) the Lessee's  compliance  with its  obligation to purchase
         the Lessor's  interest in the Property in accordance  with Section 20.2
         of the Lease, or

                  (c) the payment of the Asset  Termination  Value in accordance
         with Sections 16.2(b), 16.3 or 16.4 of the Lease, or

                  (d)  the  Lessee  failing  to  fulfill  one  or  more  of  the
         conditions to exercise of the  Remarketing  Option  pursuant to Section
         22.1 of the Lease and the Agent's receipt  pursuant to the next-to-last
         paragraph of Section 22.1 of the Lease of the Asset  Termination  Value
         in accordance with Section 20.2 of the Lease,

shall be distributed  by the Agent as promptly as possible (it being  understood
that any such payment  received by the Agent on a timely basis and in accordance
with the  provisions of the Lease shall be distributed on the date on which such
funds are so received) to pay in full or redeem the Participant  Balance of each
Participant and in the case that the amount so distributed shall be insufficient
to pay in full as  aforesaid,  then  pro rata  among  the  Participants  without
priority of one over the other, in the proportion  that the Participant  Balance
of each bears to the aggregate of all of the Participant Balances.

                  (e) Notwithstanding any other provision in this Agreement, the
Lease or any other Operative  Document to the contrary,  the Lessee,  the Agent,
the  Participants and the Lessor

                                      -9-

<PAGE>

agree that upon the maturity or acceleration  of the Lessee's  obligation to pay
the Asset Termination Value,  Residual Value Guarantee Amount or Purchase Option
Price,  any and all amounts of Cash  Collateral  that have been deposited by the
Lessee  pursuant  to the  Cash  Collateral  Agreement  and  that  have  not been
withdrawn  by the Lessee or offset or applied  by the  Lessor,  the Agent or any
Participant (in accordance  with the terms of the Cash Collateral  Agreement) as
of such maturity or  acceleration  date,  shall be required to be applied by the
Agent and the Lessor to satisfy the Lessee's obligation to pay the unpaid amount
of such  portion  of the  Asset  Termination  Value,  Purchase  Option  Price or
Residual Value Guarantee represented by the Cash Collateral, notwithstanding the
fact  that such  amounts  may not then be  actually  available,  for any  reason

         SECTION 4.1 Commitment  Fees. The Lessee shall pay to the Agent for the
account of each  Participant a commitment  fee (the  "Commitment  Fees") for the
period from and including the Closing Date to the earlier of (i) the  Completion
Date  or  (ii)  the  Outside  Completion  Date,  computed  in the  case  of each
Participant at a rate per annum equal to the  Commitment Fee Rate  applicable to

                                    SECTION 5

                        CERTAIN INTENTIONS OF THE PARTIES

         SECTION 5.1 Nature of Transaction.  (a) It is the intent of the parties
hereto  that:  (i) the  Lease  constitutes  an  "operating  lease"  pursuant  to
Statement of Financial  Accounting Standards No. 13, as amended, for purposes of
Lessee's financial reporting,  and (ii) for purposes of federal, state and local
income  or  franchise  taxes and for any other tax  imposed  on or  measured  by
income,  the  transaction  contemplated  hereby is a financing  arrangement  and
preserves  ownership  in the  Property in the Lessee.  Nevertheless,  the Lessee
acknowledges  and agrees that neither the Agent,  the Lessor 


                                      -14-

<PAGE>

nor any  Participant  has made any  representations  or warranties to the Lessee
concerning  the  tax,  accounting  or  legal  characteristics  of the  Operative
Documents and that the Lessee has obtained and relied upon such tax,  accounting
and legal advice concerning the Operative Documents as it deems appropriate.

                  Notwithstanding any provision of this Participation  Agreement
to the contrary, the parties hereto agree and declare that: (i) the transactions
contemplated by the Lease are intended to have a dual, rather than single, form;
and (ii) all  references in this  Participation  Agreement to the "lease" of the
Property which fail to reference such dual form do so as a matter of convenience
only and do not reflect the intent of the parties  hereto as to the true form of
such  arrangements.  The parties  hereto agree that,  in  accordance  with their
intentions  expressed herein and the substance of the transactions  contemplated
hereby,  Lessee (and not Lessor)  shall be treated as the owner of the  Property
for  federal,  state,  and local  income and property tax purposes and the Lease
shall be treated as a financing  arrangement.  Lessee  shall be entitled to take
any  deduction,  credit,  allowance  or other  reporting,  filing  or other  tax
position consistent with such characterizations. The Lessor and the Participants
shall file any  federal,  state or local  income tax  returns,  reports or other
statements in a manner which is consistent with the foregoing provisions of this
Section 5.1;  provided,  that the Lessor and any Participant may take a position
that is  inconsistent  with the Lessee's status as owner of the Property if: (x)
there has been a change in law or  regulation  so  requiring  as supported by an
opinion  of  counsel  reasonably  acceptable  to the  Lessee  that  there is not
substantial authority for such a consistent reporting position; or (y) (A) there
has been an  administrative or judicial holding that the Lessee is not the owner
of the  Property for such tax  purposes,  (B) the Lessee has no right to contest
such holding pursuant to Section 13.5 of the  Participation  Agreement,  and (C)
the  Lessee's  lack of right to  contest  is not the  result of an  Indemnitee's
waiver of its right to indemnification  pursuant to Section  13.5(f)(iii) of the
Participation  Agreement or failure of the amount at issue to exceed the minimum
amount set forth in Section 13.5(f)(iv)(B) of the Participation Agreement.

                  (b)   Specifically,   without   limiting  the   generality  of
subsection  (a) of this Section 5.1,  the parties  hereto  intend and agree that
with  respect to the nature of the  transactions  evidenced  by the Lease in the
context of the exercise of remedies  under the Operative  Documents,  including,
without limitation, in the case of any insolvency or receivership proceedings or
a  petition  under the United  States  bankruptcy  laws or any other  applicable
insolvency  laws or  statute  of the  United  States of  America or any State or
Commonwealth  thereof affecting the Lessee, the Lessor or any Participant or any
enforcement  or  collection  actions,  (i)  the  transactions  evidenced  by the
Operative  Documents  are  loans  made by the  Lessor  and the  Participants  as
unrelated  third party lenders to the Lessee  secured by the Property,  (ii) the
obligations  of the Lessee  under the Lease to pay Basic  Rent and  Supplemental
Rent or Asset  Termination Value in connection with any purchase of the Property
pursuant to the Lease shall be treated as payments of interest on and  principal
of,  respectively,  loans from the Lessor and the  Participants  to the  Lessee,
(iii) the Lease  grants a security  interest  and  mortgage  or deed of trust or
lien,  as the case may be, in the Property and the  collateral  described in the
Mortgage to the Lessor,  the Agent and the  Participants  to secure the Lessee's
performance  and payment of all amounts under the Lease and the other  Operative
Documents.

                                      -15-
<PAGE>

         SECTION 5.2 Amounts Due Under Lease.  Anything else herein or elsewhere
to the contrary notwithstanding,  it is the intention of the Lessee, the Lessor,
the  Participants  and the Agent that: (i) the amount and timing of installments
of Basic Rent due and payable  from time to time from the Lessee under the Lease
shall be equal to the aggregate  payments due to the  Participants in respect of
their  Participation  Interests on each Payment Date;  (ii) if the Lessee elects
the Purchase  Option or becomes  obligated  to purchase  the Property  under the
Lease, the Participation  Interests, all fees and all of the interest on overdue
amounts thereon and all other obligations of the Lessee owing to the Lessor, the
Participants  and the Agent  shall be paid in full by the  Lessee;  (iii) if the
Lessee properly elects the Remarketing Option, the Lessee shall only be required
to pay to the Lessor the  proceeds  of the sale of the  Property,  the  Residual
Value  Guarantee  Amount  and any  amounts  due  pursuant  to Section 13 of this
Participation  Agreement and Section 22.2 of the Lease (which aggregate  amounts
may be less than the Asset Termination Value); and (iv) upon an Event of Default
resulting in an acceleration of the Lessee's obligation to purchase the Property
under the Lease,  the amounts then due and payable by the Lessee under the Lease
shall include all amounts necessary to pay in full the Asset Termination  Value,
plus all other amounts then due from the Lessee to the  Participants,  the Agent
and the Lessor under the Operative Documents.

         SECTION  8.2  Representations  of the  Participants.  Each  Participant
represents and warrants to the Lessor,  each of the other  Participants  and the
Lessee as follows:

                  (a) No Plan Assets.  Such  Participant  is not and will not be
funding  its  Participation  Interest  hereunder,  and  is  not  performing  its
obligations  under the  Operative  Documents,  with the  assets of an  "employee
benefit  plan" (as defined in Section 3(3) of ERISA) which is subject to Title I

advancing  of any amount  with  respect  to its  Participation  Interest  on any
Funding Date shall  constitute an affirmation by the subject  Participant of the
preceding representation and warranty.

                  (b) Due  Organization,  etc. It is either (i) a duly organized
and validly existing corporation in good standing under the laws of the state of

validly  existing  under  the  laws of the  United  States  or  (iii) a  banking
corporation   duly  organized  and  validly  existing  under  the  laws  of  the
jurisdiction of its organization, and, in each case, has the corporate power and
authority  to  execute,  deliver and carry out the terms and  provisions  of the
Operative Documents to which it is a party.

                  (c) Authorization;  No Conflict.  The execution,  delivery and
performance  of each  Operative  Document  to which it is or will be a party has
been  duly  authorized  by all  necessary  action  on its part and  neither  the
execution  and  delivery  thereof,  nor  the  consummation  of the  transactions
contemplated  thereby, nor compliance by it with any of the terms and provisions
thereof  (i) does or will  require  any  approval  or consent of any  trustee or
holders of any of its indebtedness or obligations,  (ii) does or will contravene
any current law,  governmental  rule or  regulation  of the United States or the
state or country of its organization, (iii) does or will contravene or result in
any breach of or constitute any default under,  or result in the creation of any
Lien upon any of its property under, its certificate of incorporation or bylaws,
articles of  association  or other  organizational  documents or any  indenture,
mortgage, deed of trust,  conditional sales contract,  credit agreement or other
agreement or instrument to which it is a party or by which it or its  properties
may be bound or affected or (iv) does or will require any Governmental Action by
any Governmental Authority.

                  (d)  Enforceability,  etc. Each Operative Document to which it
is a party has been, or on or before the Closing Date or applicable Funding Date
or Land Interest Acquisition Date will be, duly executed and delivered by it and
each  such  Operative  Document  to  which  it is a party  constitutes,  or upon
execution and delivery will constitute,  a legal,  valid and binding  obligation
enforceable against it in accordance with the terms thereof,  except as the same
may be limited by

                                      -26-

<PAGE>

insolvency,  bankruptcy,  reorganization  or other laws relating to or affecting
creditors' rights or by general equitable principles.

                  (e) Litigation.  There is no action or proceeding  pending or,
to its  knowledge,  threatened  to  which  it is or will be a party  before  any
Governmental Authority that is reasonably likely to be adversely determined and,
if adversely  determined,  would  materially and adversely affect its ability to
perform its obligations under the Operative Documents to which it is a party.

         SECTION 8.3  Representations  of the Lessee.  The Lessee represents and
warrants to each of the other parties hereto that:

                  (a) Corporate  Status.  The Lessee (i) is a  corporation  duly
organized,  validly existing and in good standing under the laws of the State of
Delaware and (ii) has duly  qualified  and is  authorized to do business and has
obtained  a  certificate  of  authority  to  transact   business  as  a  foreign
corporation  in  the  States  of  California  and  Colorado  and in  each  other
jurisdiction  where  the  failure  to so  qualify  is  reasonably  likely  to be
Material.

                  (b) Corporate  Power and  Authority.  The Lessee has corporate
power and authority to execute,  deliver and carry out the terms and  provisions
of the  Operative  Documents to which it is or will be a party and has taken all
necessary corporate action to authorize the execution,  delivery and performance
of the  Operative  Documents  to which it is or will be a party  and has or will
have duly executed and delivered each Operative Document required to be executed
and delivered by it and, assuming the due authorization,  execution and delivery
thereof on the part of each other party thereto,  each such  Operative  Document
constitutes or will constitute a legal, valid and binding obligation enforceable
against it in  accordance  with its terms,  except as the same may be limited by
insolvency,  bankruptcy,  reorganization  or other laws relating to or affecting
the enforcement of creditors' rights or by general equitable principles.

                  (c)  No  Violation.   Neither  the  execution,   delivery  and
performance by the Lessee of the Operative Documents to which it is or will be a
party nor compliance with the terms and provisions thereof, nor the consummation
by the Lessee of the  transactions  contemplated  therein  (i) will  result in a
violation by the Lessee of any applicable  provision of any law, statute,  rule,
regulation,  order,  writ,  injunction  or decree  of any court or  governmental
instrumentality  having  jurisdiction over the Lessee or the Property that would
(x) adversely affect the validity or enforceability  of the Operative  Documents
to which the Lessee is a party,  or the title to, or value or condition  of, the
Property,  or (y) have a Material Adverse Effect on the  consolidated  financial
position,  business or consolidated  results of operations of the Lessee, or (z)
have an adverse  effect on the ability of the Lessee to perform its  obligations
under the Operative  Documents,  (ii) will conflict with or result in any breach
under,  or  (other  than  pursuant  to the  Operative  Documents)  result in the
creation or imposition of (or the  obligation to create or impose) any Lien upon
any of the property or assets of Lessee pursuant to the terms of, any indenture,
loan  agreement or other  agreement for borrowed  money to which the Lessee is a
party or by which it or any of its  property  or  assets is bound or to which it
may be subject (other than Permitted Liens), or (iii) will violate any provision
of the certificate or articles of incorporation or bylaws of the Lessee.

                                      -27-
<PAGE>

                  (d)  Litigation.  There are no actions,  suits or  proceedings
pending or, to the knowledge of the Lessee,  threatened  (i) that are reasonably
likely to have a Material  Adverse  Effect or (ii) that question the validity of
the  Operative  Documents or the rights or remedies of the Lessor,  the Agent or
the Participants  with respect to the Lessee or the Property under the Operative
Documents.

                  (e)  Governmental  Approvals.  No  Governmental  Action by any
Governmental  Authority having  jurisdiction  over the Lessee or the Property is
required  to  authorize  or is required in  connection  with (i) the  execution,
delivery and  performance  by the Lessee of any  Operative  Document or (ii) the
legality,  validity,  binding effect or enforceability against the Lessee of any
Operative  Document,  except  for  the  filing  or  recording  of the  Operative
Documents  listed in Section  8.4(f)  hereof with the  appropriate  Governmental
Authorities,  all of which  will  have  been  completed  on or prior to the Land
Interest Acquisition Date.

                  (f)  Investment  Company Act. The Lessee is not an "investment
company"  or a company  "controlled"  by an  "investment  company,"  within  the
meaning of the Investment Company Act.

                  (g) Public  Utility  Holding  Company Act. The Lessee is not a
"holding  company,  or a "subsidiary  company," or an  "affiliate" of a "holding
company, or of a "subsidiary company" of a "holding company", within the meaning
of the Public Utility Holding Company Act of 1935, as amended.

                  (h) Accuracy of Information  Furnished.  None of the Operative
Documents  and  none  of  the  other  certificates,  statements  or  information
furnished  to the Lessor,  the Agent or any  Participant  by or on behalf of the
Lessee or any of its Subsidiaries in connection with the Operative  Documents or
the  transactions  contemplated  thereby (taken together with all such Operative
Documents, certificates, statements or information) contains or will contain any
untrue  statement  of a material  fact or omits or will omit to state a material
fact necessary to make the  statements  therein,  in light of the  circumstances
under which they were made, not  misleading (it being  understood by the Lessor,
the Agent or any Participant that the projections and forecasts  provided by the
Lessee are not to be viewed as facts and that actual  results  during the period
or periods  covered  by such  projections  and  forecasts  may  differ  from the
projected or forecasted results).

                  (i) Taxes.  All United States  federal  income tax returns and
all other  Material tax returns  which are required to have been filed have been
or will be prepared in accordance  with applicable law and filed by or on behalf
of the Lessee by the respective due dates,  including extensions,  and all taxes
due with  respect to the Lessee  pursuant  to such  returns or  pursuant  to any
assessment  received  by the  Lessee  have  been or will be paid.  The  charges,
accruals  and  reserves  on the books of the Lessee in respect of taxes or other
governmental charges are, in the opinion of the Lessee, adequate.

                  (j) Compliance with ERISA.  Each member of the ERISA Group has
fulfilled its obligations  under the minimum funding  standards of ERISA and the
Code with respect to each Plan and is in  compliance  in all  Material  respects
with the presently  applicable  provisions of ERISA 

                                      -29-
<PAGE>

and the Code with  respect  to each Plan.  No member of the ERISA  Group has (i)
sought a waiver of the minimum funding standard under Section 412 of the Code in
respect of any Plan, (ii) failed to make any contribution or payment to any Plan
or  Multiemployer  Plan or in respect of any  Benefit  Arrangement,  or made any
amendment to any Plan or Benefit Arrangement, which has resulted or could result
in the  imposition  of a Lien or the posting of a bond or other  security  under
ERISA or the Code or (iii) incurred any liability  under Title IV of ERISA other
than a liability to the PBGC for premiums under Section 4007 of ERISA.

                  (k) Environmental and Other  Regulations.  Except as set forth
in Schedule III attached  hereto,  the Lessee and the Property are in compliance
with all Environmental  Laws relating to pollution and environmental  control or
employee safety in the  jurisdiction in which the Property is located and in all
other  domestic   jurisdictions,   other  than,   with  respect  to  such  other
jurisdictions,  those Environmental Laws the non-compliance with which would not
have a Material Adverse Effect.

                  (l) Offer of  Securities,  etc.  Neither  the  Lessee  nor the
Guarantor  nor any Person  authorized  to act on their  behalf has,  directly or
indirectly,  offered  any  interest  in the  Property  or the Lease or any other
interest  similar  thereto (the sale or offer of which would be integrated  with
the sale or offer of such  interest in the Property or the Lease),  for sale to,
or  solicited  any offer to acquire any of the same from,  any Person other than
the  Participants,  the Lessor and other  "accredited  investors" (as defined in
Regulation D of the Securities and Exchange Commission).

                  (m) Financial Statements.  The audited consolidated  statement
of  financial  position of the Lessee and its  consolidated  Subsidiaries  as of
March 31, 1997 and the related consolidated statements of income,  shareholder's
equity and cash flows for the fiscal  year then  ended,  reported  on by Ernst &
Young,  LLP,  a copy of which  has been  delivered  to each of the  Lessor,  the
Participants  and  the  Agent,  present  fairly  in all  material  respects,  in
conformity with generally accepted accounting principles, the financial position
of the Lessee as of such date and its results of  operations  and cash flows for
such fiscal year.

                  (n) No Violation or Default. Neither the Lessee nor any of the
Lessee's  Subsidiaries  is in violation of or in default with respect to (i) any
Requirement of Law applicable to such Person or (ii) any Contractual  Obligation
of such Person,  where,  in each case,  such  violation or default is reasonably
likely to have a Material Adverse Effect. Without limiting the generality of the
foregoing,  neither the Lessee nor any of the  Lessee's  Subsidiaries  (A) is in
violation of any Environmental  Laws, (B) to the best of the Lessee's knowledge,
has any liability or potential liability under any Environmental Laws or (C) has
received written notice or other written communication of an investigation or is
under  investigation by any Governmental  Authority having jurisdiction over the
Lessee  or  any  of  the  Lessee's  Subsidiaries  having  authority  to  enforce
Environmental   Laws,  where,  in  each  case,  such  violation,   liability  or
investigation  could  reasonably be expected to have a Material  Adverse Effect,
nor, to the best of the Lessee's  knowledge,  have any Hazardous  Materials been
released  or  disposed  of on any of the  properties  owned by the Lessee or the
Lessee's  Subsidiaries  which,  either  individually or in the aggregate,  could
reasonably be expected to have a Material Adverse Effect. No Event of Default or
Default has occurred and is continuing.

                  (o)  Title;  Possession  Under  Leases.  The  Lessee  and  the
Lessee's  Subsidiaries  (i) own and have  good  title  (without  regard to minor
defects  of title),  or  leasehold  interests  in,  all their  other  respective
properties  and assets  which are material to the business of the Lessee and its
Subsidiaries  taken  as a  whole  as  reflected  in the  most  recent  Financial
Statements  delivered to the Agent (except those assets and properties  disposed
of  since  the  date  of such  Financial  Statements  in  compliance  with  this
Agreement) and (ii) own and have good title (without  regard to minor defects of
title) to, or  leasehold  interests  in, all  respective  properties  and assets
acquired by the Lessee and the Lessee's  Subsidiaries  since such date which are
material  to the  business of the Lessee and its  Subsidiaries  taken as a whole
(except  those  assets  and  properties  disposed  of in  compliance  with  this
Agreement).  Such  assets and  properties  are  subject  to no Lien,  except for
Permitted Liens.

                  (p) Patent  and Other  Rights.  The  Lessee  and the  Lessee's
Subsidiaries own or license under validly  existing  agreements (or could obtain
such  ownership,  possession or license on terms not  materially  adverse to the
Lessee and its  Subsidiaries,  taken as a whole,  and under  circumstances  that
could not reasonably be expected to have a Material  Adverse  Effect),  and have
the full right to license without the consent of any other Person,  all patents,
licenses,  trademarks, trade names, trade secrets, service marks, copyrights and
all rights with respect thereto, which are material to conduct the businesses of
the Lessee and its Subsidiaries (taken as a whole) as now conducted.

                  (q)  Solvency,  Etc.  The  Lessee  and  each  of its  Material
Subsidiaries  is Solvent and,  after the execution and delivery of the Operative
Documents and the consummation of the transactions contemplated thereby, will be

Lessee's  Subsidiaries  and none of their  properties  is  affected by any fire,
explosion, strike, lockout or other labor dispute, earthquake,  embargo or other
casualty that is reasonably  likely to have a Material Adverse Effect. As of the
Closing Date, there are no disputes  presently  subject to grievance  procedure,
arbitration  or litigation  under any of the collective  bargaining  agreements,
employment  contracts or employee welfare or incentive plans to which the Lessee
or any of the  Lessee's  Subsidiaries  is a  party,  an  there  are no  strikes,
lockouts, work stoppages or slowdowns,  or, to the best knowledge of the Lessee,
jurisdictional  disputes or organizing  activities occurring or threatened which
alone or in the  aggregate  are  reasonably  likely to have a  Material  Adverse
Effect.

         SECTION 8.4  Representations of the Lessee With Respect to the Property
on the Land Interest Acquisition Date. The Lessee hereby represents and warrants
as follows:

                  (a) Representations. The representations and warranties of the

Requirements of Law (including,  without limitation,  Title III of the Americans
with Disabilities Act, all zoning and land use laws and Environmental  Laws) and
Insurance Requirements,  except for such Requirements of Law as the Lessee shall
be contesting in good faith by  appropriate  proceedings.  The related Plans and
Specifications  have  been or will  be  prepared  in all  material  respects  in
accordance with applicable  Requirements of Law (including,  without limitation,
Title III of the Americans with Disabilities Act, applicable  Environmental Laws
and  building,  planning,  zoning  and fire  codes) and upon  completion  of the
facility in accordance with the Plans and Specifications,  such facility and the
other  Improvements  on such  Property  will not encroach in any manner onto any
adjoining land (except as permitted by express  written  easements or as insured
by appropriate  title insurance) and such facility and other  Improvements  will
comply  in  all  Material  respects  with  all  applicable  Requirements  of Law
(including,  without  limitation,  Title III of the Americans with  Disabilities
Act, all applicable Environmental Laws and building,  planning,  zoning and fire
codes).  Upon  completion of such facility in accordance  with the related Plans
and Specifications,  the Improvements including, without limitation,  structural
members, the plumbing, heating, air conditioning and electrical systems thereof,
and all water, sewer,  electric,  gas, telephone and drainage facilities will be
completed  in a  workmanlike  manner  and  in  accordance  with  the  Plans  and
Specifications  and will be in first class working  condition and fit for use as
administration,  manufacturing  design and warehouse  facilities,  and all other
utilities required to adequately service the Improvements for their intended use
are or will be  available  and  "tapped  on" and hooked up  pursuant to adequate
permits  (including  any that may be  required  under  applicable  Environmental
Laws).  There is no action,  suit or  proceeding  (including  any  proceeding in
condemnation  or eminent domain or under any  Environmental  Law) pending or, to
the best of the Lessee's  knowledge,  threatened with respect to the Lessee, its
Affiliates or such Property  which  adversely  affects the title to, or the use,
operation or value of, the Property.  As of the Land Interest  Acquisition Date,
no fire or other casualty with respect to the Property shall have occurred,  and
as of each other  Funding  Date,  no fire or other  casualty with respect to the
Property  shall have  occurred  that  constitutes  a  Significant  Casualty with
respect to which the Lessee  shall have  delivered a  Termination  Notice  under
Section 16.1 of the Lease.  The Property has or will have available all material
services  of  public  facilities  and  other  utilities  necessary  for  use and

Plans  and  Specifications,   are  located  in,  and  vehicular  access  to  the
Improvements  on such  Property  is provided  by,  either  public  rights-of-way

authorizations,  consents,  permits (including,  without  limitation,  building,
demolition and environmental permits,  licenses,  approvals,  authorizations and
consents), easements and rights-of-way, including proof and dedication, required
for (x) the use, treatment,  storage, transport,  disposal or disposition of any
Hazardous  Substance on, at, under or from such Property during the construction
of the  Improvements  thereon,  and (y)  construction  of such  Improvements  in
accordance with the related Plans and Specifications and the Construction Agency
Agreement   have  either  been  obtained  from  the   appropriate   Governmental
Authorities having jurisdiction or from private parties,

                                      -31-

<PAGE>


as the case  may be,  or will be  obtained  from  the  appropriate  Governmental
Authorities  having  jurisdiction or from private  parties,  as the case may be,
prior to commencing any such  construction  or use and operation,  as applicable
and will in each case be  maintained  by the Lessee during the periods for which
they are required by Applicable Law or such Governmental Authorities.

                  (c)  Title.  The Deed  providing  for the  acquisition  of the
Property is  sufficient  to convey title to the Property in fee simple,  subject
only to Permitted  Exceptions.  Upon conveyance of the Deed on the Land Interest
Acquisition  Date, the Lessor will own fee simple title in the Land Interest and
any  Improvements and will have the right to grant the Mortgage on the Property.
The Lessor  will at all times  during the Term have good title to all  Equipment
wherever located and to any Improvements.

                  (d)  Insurance.  The Lessee has  obtained  insurance  coverage
covering the Property which meets the  requirements of Article XIV of the Lease,
and such coverage is in full force and effect.

                  (e)  Lease.  Upon the  execution  and  delivery  of the  Lease
Supplement to the Lease, (i) the Lessee will have  unconditionally  accepted the
Property and will be bound by the terms of the Lease  Supplement and will have a
valid  leasehold  interest  in the  Property,  subject  only  to  the  Permitted
Exceptions;  (ii) the  Lessee's  obligation  to pay Rent will be an  independent
covenant and no right of deduction or offset will exist with respect to any Rent
or other sums  payable  under the Lease;  and (iii) no Rent under the Lease will
have been  prepaid and the Lessee will have no right to prepay the Rent,  except
as specifically set forth therein.

                  (f)  Protection  of  Interests.   (i)  On  the  Land  Interest
Acquisition Date, the Lease Supplement,  the Assignment of Lease, the Supplement
to Assignment of Lease, the Consent to Assignment and the Mortgage are each in a
form sufficient,  and have been recorded in all recording offices necessary,  to
grant perfected first priority liens on the Property to the Agent or the Lessor,
as the  case may be,  (ii) the  Agent  Financing  Statements  are each in a form
sufficient,  and have been filed in all filing  offices  necessary,  to create a

         SECTION 8.5 Representations of the Lessee With Respect to Each Advance.
The Lessee  hereby  represents  and warrants as of each Funding Date on which an
Advance is made as follows:

                  (a) Representations. The representations and warranties of the
Construction  Agent  and  the  Lessee  set  forth  in  the  Operative  Documents
(including the representations and warranties set forth in Sections 8.3 and 8.4)
are true and correct in all Material  respects on and as of such  Funding  Date,
except to the extent such  representations  or  warranties  relate  solely to an
earlier date, in which case such  representations and warranties shall have been
true and correct in all Material  respects on and as of such earlier  date.  The
Construction  Agent and the Lessee are in  compliance  in all Material  respects
with their respective obligations under the Operative Documents and there exists
no  Default  or Event of  Default  which is  continuing.  No Default or Event of
Default  will occur as a result  of, or after  giving  effect  to,  the  Advance
requested by the Acquisition Request or the Funding Request on such date.

                  (b) Improvements. Construction of the Improvements to date has
been performed in a good and  workmanlike  manner,  substantially  in accordance
with  the  Plans  and  Specifications  and  in  compliance  with  all  Insurance
Requirements and Requirements of Law.

                  (c) No Liens.  There have been no Liens  against the  Property
since the  recordation  of the Deed,  the Lease  Supplement,  the  Assignment of
Lease, the Consent to Assignment or the Mortgage other than Permitted Exceptions
and Liens that have been  removed or bonded by or on behalf of the Lessee to the
satisfaction of the Lessor and the Agent. The  Participation  Interests  funding
such Advance are secured by the Lien of the Mortgage.

                  (d) Advance.  The amount of the Advance  requested  represents
amounts  owing in  respect  of the  acquisition  price of the Land  Interest  or
amounts that the Lessee  reasonably  believes will be due in the sixty (60) days
following  such Advance from the Lessee to third  parties in respect of Property
Improvements Costs, or amounts paid by the Lessee to third parties in respect of
Property  Costs for which the Lessee has not  previously  been  reimbursed by an
Advance. The conditions precedent to such Advance and the related remittances by
the  Participants  with  respect  thereto  set  forth  in  Section  6 have  been
satisfied.

                  (e) Lease.  Upon the execution and delivery of each  Equipment
Schedule  to the  Lease,  the  Lessee  will have  unconditionally  accepted  the
Equipment,  if any,  subject  to the  Lease  Supplement  and will  have good and
marketable title to a valid and subsisting leasehold interest in such Equipment,
subject only to Permitted Exceptions.

                  (f)  Protection  of  Interests.  On each  Funding Date for the
acquisition of Equipment,  (i) the Lease  Supplement,  the applicable  Equipment
Schedule and the Mortgage are each a form sufficient to grant perfected Liens on
the Lessee's and the Lessor's interests,  respectively,  in the Equipment to the
Lessor and Agent, respectively,  (ii) the Agent Financing Statements are each in
a form  sufficient,  and have been filed in all  filing  offices  necessary,  to
create a valid and perfected first priority  security  interest in such interest
in such Equipment,  and (iii) the Lessor Financing Statements are each in a form
sufficient,  and have been filed in all filing offices necessary, to perfect 

                                      -33-
<PAGE>


the Lessor's  interest in such Equipment under the Lease to the extent the Lease
is a security agreement.

                  (g)  Title  Insurance  Date  Down  Endorsement.  Prior to each
Advance  during the  Construction  Period and prior to an Advance  following the
Construction  Period for Property  Improvement  Costs to which a mechanics' lien
could take priority over the lien of the Mortgage or the lien of the Lease,  the
Lessee shall furnish the Lessor at the Lessee's  expense an endorsement or other
coverage  reasonably  acceptable to the Agent from the title  insurance  company
issuing the policies  pursuant to Section 6.1, insuring the Lessor and the Agent
that (i) all  mechanics'  or similar liens and claims for such liens which could
arise from that part of the Property  Improvements Costs previously paid for, if
any, or to be paid for with the then proposed Advance, have been waived and (ii)
there has not been filed with  respect to all or any parts of the Land  Interest
and  Improvements  any  mechanics' or similar liens or claims of such liens that
are not discharged of record, or insured over by the title insurance company, in
respect of any part of the Land Interest and Improvements.

                       (ii) Deliver to the Agent from time to time, as the Agent
                  may request,  schedules  setting forth all  insurance  then in

                      (iii)  Notwithstanding  clauses  (i) and (ii)  above,  the
                  Lessee and any of its  Subsidiaries may self-insure in lieu of
                  maintaining  all or a portion of the insurance  required to be
                  maintained  pursuant  to this  Section  10.1(d)  to the extent
                  determined   by  the   Lessee's   Board  of  Directors  to  be
                  appropriate  and in the best  interests  of the Lessee and its
                  Subsidiaries  taken  as a  whole  and  except  to  the  extent
                  provided  in  Article  XV of the  Lease  with  respect  to the

         Governmental  Charges  prior to the date upon  which  penalties  accrue
         thereon  which,  if unpaid,  are  reasonably  likely to have a Material
         Adverse Effect, except such taxes and other Governmental Charges as may
         in good faith be contested or disputed,  or for which  arrangements for
         deferred  payment  have  been  made,  provided  that in each  such case
         appropriate reserves are maintained in accordance with GAAP, and except
         as  otherwise  provided  in Section  13 hereof or  Article  XIII of the

         activities  in  compliance  with  all  Applicable  Law and  Contractual

         business   practices,   and  (iv)  pay  and  perform  all   Contractual
         Obligations  as and when due  (except  to the extent  disputed  in good
         faith by the Lessee or the appropriate Subsidiary and where non-payment
         would not be reasonably  expected to have a Material  Adverse  Effect).
         The Lessee shall  maintain  its chief  executive  office and  principal
         place of business in the United States and shall not relocate its chief
         executive  office or principal place of business  outside of California

         cause  or  permit  any  of  its  obligations,  except  the  obligations
         constituting  Senior  Indebtedness  to  constitute  "Designated  Senior
         Indebtedness"   under  the   indentures   governing   the   Convertible
         Subordinated  Debentures (it being  understood  that the obligations of
         the Lessee  under the  Operative  Documents  to  purchase or to cause a
         third party  purchase  the  Property and to pay Rent shall at all times
         constitute "Designated Senior Indebtedness").

                  (o) ERISA.  Neither the Lessee nor any ERISA  Affiliate  shall
         (i) adopt or institute any defined benefit  Employee  Benefit Plan that
         is an employee  pension benefit plan within the meaning of Section 3(2)
         of ERISA,  (ii) take any  action  which will  result in the  partial or
         complete  withdrawal,  within the meanings of sections 4203 and 4205 of
         ERISA, from a Multiemployer  Plan, (iii) engage or permit any Person to
         engage in any transaction prohibited by section 406 of ERISA or section
         4975 of the Code involving any Employee  Benefit Plan or  Multiemployer
         Plan which would  subject  either the Lessee or any ERISA  Affiliate to
         any tax, penalty or other liability including a liability to indemnify,
         (iv) incur or allow to exist any accumulated funding deficiency (within
         the  meaning  of  section  412 of the Code or  section  302 of  ERISA),
         excluding all extensions permitted by law or contract, (v) fail to make
         full  payment  when  due of all  amounts  due as  contributions  to any

         the  requirements  of section 4980B of the Code or Part 6 of Title I(B)
         of ERISA,  or (vii) adopt any  amendment to any  Employee  Benefit Plan
         which  would  require  the  posting  of  security  pursuant  to section
         401(a)(29) of the Code,  if any of such actions or inactions  described
         in clauses (vi)-(vii), either individually or cumulatively,  would have
         a Material Adverse Effect.

                  (p) Transactions  With Affiliates.  Neither the Lessee nor any
         of its  Subsidiaries  shall enter into any Contractual  Obligation with
         any  Affiliate or engage in any other  transaction  with any  Affiliate
         except  upon  terms  at  least  as  favorable  to the  Lessee  or  such
         Subsidiary as an arms-length transaction with unaffiliated Persons.

                  (q)  Accounting  Changes.  Neither  the  Lessee nor any of its
         Subsidiaries  shall  change (i) its fiscal  year  (currently  April 1 -
         March 31) or (ii) its accounting practices except as permitted by GAAP.

                  (r)      Financial Covenants.

                        (i) the Lessee  shall not  permit its Quick  Ratio to be

                           Lessee's consolidated  quarterly net income (ignoring
                           any quarterly losses) for each quarter after the base
                           date  through  and  including   the  quarter   ending
                           immediately prior to the determination date;

                                                       plus

                               (C)   Seventy-Five   percent  (75%)  of  the  Net
                           Proceeds  of  all  Equity  Securities  issued  by the
                           Lessee and its  Subsidiaries  (excluding any issuance
                           where the total  proceeds are less than  $10,000,000)
                           during  the  period  commencing  on the base date and
                           ending on the determination date;

                                                       plus

                               (D)  Ninety  percent  (90%)  of the Net  Proceeds
                           derived  from  the  conversion  of  the   Convertible
                           Subordinated Debentures;

                                                       minus

                               (E) the lesser of (1) the  aggregate  amount paid
                           by the Lessee to repurchase its capital stock and (2)
                           $50,000,000.

                      (iii) In any consecutive  four-quarter  period, the Lessee
                  shall  not  permit  (A) more  than two  quarterly  net  losses

                       (iv) The Lessee  shall not permit its Senior  Funded Debt
                  Ratio  on the  last  day  of  any  fiscal  quarter  to  exceed
                  thirty-five percent (35%).

                  (s) Appraisal.  On or prior to the date that is not later than
30 days (or such later date as is  acceptable to the Agent and the Lessor) after
the Land Interest  Acquisition  Date, the Agent, the Lessor and the Participants
shall have  received an  Appraisal of that portion of the Phase I project on the
Land Interest described in the Preliminary Letter of Value delivered pursuant to
Section 6.1(d),  which Appraisal shall (i) show that the Fair Market Sales Value
of the  Land  Interest


                                      -49-
<PAGE>

with  respect to such  Property as of the  projected  Completion  Date shall not
exceed  25% of the  Fair  Market  Sales  Value  of such  Land  Interest  and the
Improvements  to be  constructed  thereon  in  accordance  with  the  Plans  and
Specifications for Property,  and (ii) show as of the projected  Completion Date
the Fair Market  Sales Value of such Land  Interest and the  Improvements  to be
constructed thereon in accordance with the Plans and  Specifications,  and (iii)
meet the other  applicable  requirements set forth in the definition of the term
"Appraisal" contained in Appendix 1.

                  (t) No Impairment of Deposits. The Lessee shall not, nor shall
it permit any of its  Subsidiaries  to,  directly or  indirectly,  enter into or
become bound by any agreement,  instrument,  indenture or other obligation which
could  directly or indirectly  restrict,  prohibit or require the consent of any
Person to the making by the  Lessee of any  deposit  of Cash  Collateral  or the
realization thereon or utilization thereof (or of any earnings thereon or of any
other Collateral) by the Lessor, the Agent or any of the Participants.

         SECTION 10.2. Cooperation with the Lessee. The Lessor, the Participants
and the Agent  shall,  to the extent  reasonably  requested  by the Lessee  (but
without assuming additional liabilities,  duties or other obligations on account
thereof), at the Lessee's expense,  cooperate with the Lessee in connection with
its covenants contained herein including,  without  limitation,  at any time and
from time to time, upon the request of the Lessee,  to promptly and duly execute
and  deliver  any and all such  further  instruments,  documents  and  financing
statements  (and  continuation  statements  related  thereto)  as the Lessee may
reasonably request in order to perform such covenants.

         SECTION 10.3. Covenants of the Lessor. The Lessor hereby agrees that so
long as this Participation Agreement is in effect:

                  (a)  Discharge of Liens.  The Lessor will not create or permit
to exist at any time, and will, at its own cost and expense,  promptly take such
action as may be necessary duly to discharge, or to cause to be discharged,  all
Lessor Liens on the Property  attributable to it;  provided,  however,  that the
Lessor shall not be required to so discharge any such Lessor Lien while the same
is  being  contested  in  good  faith  by  appropriate   proceedings  diligently
prosecuted so long as such proceedings  shall not involve any material danger of
impairment  of the Liens of the Lease or the Security  Documents or of the sale,
forfeiture or loss of, and shall not interfere with the use or  disposition  of,
the Property or title thereto or any interest therein or the payment of Rent.

                  (b) Change of Chief Place of  Business.  The Lessor shall give
prompt  notice  to the  Lessee  and the  Agent if the  Lessor's  chief  place of
business or chief executive office,  or the office where the records  concerning
the accounts or contract rights  relating to the Property are kept,  shall cease
to be located at 135 South LaSalle  Street,  Chicago,  Illinois  60603, or if it
shall change its name, identity or corporate structure.

                                   SECTION 11.

                                 PARTICIPATIONS

         SECTION 11.1. Amendments; Actions on Default. (a) The Lessor shall have
the right to forebear from  exercising  rights  against the Lessee to the extent
the Lessor shall  determine in good faith that such  forbearance  is appropriate
and is  permitted by Section 15.5 and  Sections  11.1,  11.2 and 11.3.  Upon the
direction of the  Required  Participants,  the Lessor shall  execute any waiver,
modification  or amendment  of the Lease or the  Construction  Agency  Agreement
requested  by the  Lessee;  provided,  that:  (i) the  waiver,  modification  or
amendment is not prohibited by the forgoing  provisions of this Agreement,  (ii)
the waiver,  modification  or  amendment  does not (A)  increase  the amount the
Lessor may be  required  to pay to the Lessee or anyone  else,  or (B) reduce or
postpone (and cannot  reasonably be expected to reduce or postpone) any payments
that the Lessor would,  but for such  modification or amendment,  be expected to
receive,  or (C) release the Lessor's  interest in all or a substantial  part of
the  Property;  and (iii) the Lessor is not excused from  executing  the waiver,
modification or amendment by Section 11.3.

                  (b) The Lessor will, with reasonable promptness,  provide each
Participant  with copies of all default  notices it sends or receives  under the
Lease or Construction  Agency Agreement and notify each Participant of any Event
of Default under the Lease of which it is aware and of any other matters  which,
in the  Lessor's  reasonable  judgment,  are  likely to  materially  affect  the
payments  each  Participant  will be  required to make or be entitled to receive
under  this  Agreement,  but the  Lessor  will not in any event be liable to any
Participant  for the Lessor's  failure to do so unless such failure  constitutes
gross negligence or willful misconduct on the part of the Lessor.

                  (c) Before  taking  possession  of the Property or  exercising
foreclosure or offset rights against the Property or filing any lawsuit  against
the Lessee because of any breach by the Lessee of the Operative  Documents or if
requested in writing by any Participant at any time when an Event of Default has
occurred and is  continuing,  the Lessor shall promptly call a meeting with each
Participant  and the Agent to discuss what,  if anything,  the Lessor should do.
Such meeting shall be scheduled  during regular business hours in the offices of
the Agent, or another  appropriate  location in San Francisco,  California,  not
earlier  than five (5) and not later than  twenty (20)  Business  Days after the
Lessor's  receipt of the written  request  from a  Participant.  If the Required
Participants  shall direct the Lessor in writing to (a) send any default notices
required before a Default can become an Event of Default, or (b) bring a lawsuit
against the Lessee to enforce the Operative  Documents  when an Event of Default
has occurred and is  continuing,  then the Lessor shall send the notice or bring
the suit, and the Lessor shall prosecute any such suit with reasonable diligence
using reputable counsel.  However,  if the Agent is not a member of the Required
Participants  voting pursuant to this subsection  11.1(d) in favor of the giving
of any such notice or the bringing of any such suit, then the Lessor may require
that it first receive the written  agreement (in form  reasonably  acceptable to
the Lessor) of the members of the Required  Participants  so voting to indemnify
the Agent and the Lessor from and against all costs, liabilities and claims that
may be  incurred by or  asserted  against  the Lessor  because of the action the
Required  Participants direct the Agent or the Lessor to take. In no event shall
any Participant  instigate any suit or other action directly  against the Lessee
with  respect  to  the  Operative  Documents  or  the  Property,  even  if  such
Participant would, 

                                      -51-
<PAGE>

but for this  agreement,  be entitled to do so as a third party  beneficiary  or
otherwise under the Operative Documents.

                  (d) In the event the Lessee or its designee  fails to purchase
the  Property  after any  exercise of its  Purchase  Option or  Expiration  Date
Purchase  Obligation or following the occurrence and  continuance of an Event of
Default, the Lessor shall, if the Required  Participants shall agree in writing,
bring suit against the Lessee to enforce the Operative Documents in such form as
shall be  recommended  by reputable  counsel,  and  thereafter  the Lessor shall
prosecute the suit with  reasonable  diligence in accordance  with the advice of
reputable counsel.  If the Lessor acquires the interests of the Lessee in any of
the Property as a result of such suit or otherwise,  the Lessor shall thereafter
proceed  with  reasonable  diligence  to sell  the  Property  in a  commercially
reasonable  manner to one or more bona fide third party  purchasers and shall in
any event  endeavor to  consummate  the sale of the entire  Property  (through a
single sale of the entire  Property  or a series of sales of parts)  within five
(5) years following the date the Lessor  recovers  possession of the Property at
the best price or prices the Lessor  believes are reasonably  attainable  within
such time. Further,  after the Designated Payment Date and prior to the Lessor's
sale of the entire  Property,  the  Lessor  shall  retain a property  management
company  experienced  in the area  where the  Property  is located to manage the
operation of the Property and pursue the leasing of any  completed  Improvements
which are part of the Property.  The Lessor shall not retain an Affiliate of the
Lessor to act as the  property  manager  except  under a bona fide,  arms-length
management contract containing commercially reasonable terms. Further, after the
Designated  Payment  Date and until the Lessor  sells the  Property,  the Lessor
shall (i) endeavor in good faith to maintain,  or shall obtain the  agreement of
one or more of such tenants to maintain,  the Property in good order and repair,
(ii) procure and maintain casualty  insurance against risks customarily  insured
against by owners of comparable  properties,  in amounts sufficient to eliminate
the  effects of  coinsurance,  (iii) keep and allow each  Participant  to review
accurate books and records covering the operation of the Property,  and (iv) pay
prior to  delinquency  all taxes and  assessments  lawfully  levied  against the
Property.

                  (e)  Notwithstanding  the foregoing,  Defaulting  Participants
shall have no voting or consent  rights under this Section 11.1 and no rights to
require  the Lessor to call a meeting  pursuant  to Section  11.1(d)  until they
cease to be  Defaulting  Participants.  During  any period  that any  Defaulting
Participants  have no voting rights under this Section 11.1, only the Commitment
Percentages  of the other  Participants  that still have  voting  rights will be
considered for purposes of determining the Required Participants.

         SECTION 11.2. General.  Subject to the limitations set forth in Section
11.1 and Section 14:

                  (a) The  Lessor  shall  have the  exclusive  right to take any
action and to exercise any available powers,  rights and remedies to enforce the
obligations  of the Lessee  under the  Operative  Documents,  or to refrain from
taking any such action or exercising any such power, right or remedy.

                  (b) The  Lessor  shall be  entitled  to (i) give any  consent,
waiver or approval  requested by the Lessee with respect to any  construction or
other approval contemplated in the Lease or (ii) waive or consent to any adverse
title claims affecting the Property,  provided that, in either

                                      -52-
<PAGE>


case,  such  action  will not have a  material  adverse  effect on the  Lessee's
obligations  or  ability  to make the  payments  required  under  the  Operative
Documents, the Lessor's rights and remedies under the Operative Documents or any
Participant's rights hereunder.

         SECTION 11.3 Conflicts. Notwithstanding anything to the contrary herein
contained,  the  Lessor  shall be  entitled,  even  over the  objection  of each
Participant or the Required Participants, (i) to take any action required of the
Lessor by, or to refrain  from taking any action  prohibited  by, the  Operative
Documents  or any  law,  rule or  regulation  to which  the  Lessor  is  subject
(provided,  that this Section  shall not be construed to authorize the Lessor to
take any action required by a modification of the Operative Documents prohibited
by  Section  11.1),  and (ii)  after  notice to the  Participants,  to bring and
prosecute a suit against the Lessee in the form recommended by and in accordance
with  advice of  reputable  counsel  at any time when a breach of the  Operative
Documents  by the Lessee  shall have put the Lessor (or any of its  officers  or
employees) at risk of criminal  prosecution  or  significant  liability to third
parties or at any time after the Lessee or its  designee  fails to purchase  the
Property on the  Designated  Payment Date.  Nothing  herein  contained  shall be
construed to require the Lessor to agree to modify the Operative Documents or to
take any action or  refrain  from  taking  any  action in any manner  that could
increase  the Lessor's  liability to the Lessee or others,  that could reduce or
postpone  payments  to which the Lessor is  entitled  thereunder,  or that could
reduce the scope and  coverage  of the  indemnities  provided  for the  Lessor's
benefit therein.

         SECTION  11.4.  Refusal to Give  Consents or Fund.  If any  Participant
declines to consent to any amendment,  modification,  waiver, release or consent
for which such Participant's  consent is requested or required by reason of this
Agreement,  or if any Participant  fails to pay any amount owed by it hereunder,
the Lessor shall have the right, but not the obligation and without limiting any
other remedy of the Lessor,  to terminate such  Participant's  rights to receive
any further  payments  under  Section 3 of this  Agreement  (other than payments
required because of the Lessor's collection of any Rent applied by the Lessor as
reimbursement  for a Defaulted  Amount or  interest  on a  Defaulted  Amount) by
paying such Participant a termination fee equal to the total of:

                  (i) all amounts  actually  advanced by such Participant to the
         Lessor  under  Section 3.4 hereof  before the  termination;  excluding,
         however,  any such amounts that were repaid to such Participant  before
         the  termination  by actual  payments made to such  Participant  by the
         Lessor of, or the Lessor's offset against, sums representing:

                           (A) Such  Participant's  Commitment  Percentage times
                           any payments of Rent received by the Lessor under the
                           Lease; plus

                           (B) Such  Participant's  Commitment  Percentage times
                           any sales  proceeds  received by the Lessor under the
                           Lease; and

                  (ii)     Such Participant's Commitment Percentage, times:

                           (A) the  then  accrued  but  unpaid  Basic  Rent  and
                           Commitment  Fees due under  the Lease and  hereunder;
                           plus

                                      -53-
<PAGE>

                           (B)  interest  on past due amounts  described  in the
                           preceding  clause (A)  computed at the Federal  Funds
                           Effective Rate; plus

                           (C)  interest  on any amounts  (other  than  interest
                           itself)  past due from the  Lessee  or its  designees
                           under  the  Operative  Documents,   computed  at  the
                           Federal Funds Effective Rate.

Such  Participant's  rights  to  receive  payments  equal to such  Participant's
Commitment  Percentage of any Rent applied by the Lessor as reimbursement  for a
Defaulted  Amount or  interest on a  Defaulted  Amount  shall not be impaired or
affected by any termination contemplated in this Section 11.4; accordingly,  the
Lessor shall not, as a condition to such a termination, be required to reimburse
such  Participant for any payments such  Participant has made in connection with
Defaulted Amounts pursuant to Section 3.3.

         SECTION 11.5. Required Repayments.  Each Participant shall repay to the
Lessor,  upon  written  request or demand by the Lessor (i) any sums paid by the
Lessor to such  Participant  under this Agreement from, or that were computed by
reference  to, any Rent or other  amounts  which the Lessor shall be required to
return or pay over to another  party,  whether  pursuant  to any  bankruptcy  or
insolvency  law or proceeding or otherwise and (ii) any interest or other amount
that the Lessor is also  required to pay to another  party with  respect to such
sums. Such repayment by any  Participant  shall not constitute a release of such
Participant's  right to receive such Participant's  Commitment  Percentage times
the amount of any such Rent or any such other amount (or any  interest  thereon)
that the Lessor may later recover.

         SECTION 11.6. Indemnification. Each Participant agrees to indemnify and
defend the Lessor (to the extent not  reimbursed  by the Lessee  within ten (10)
days after demand) from and against such Participant's  Commitment Percentage of
any  and  all  liabilities,   obligations,  claims,  expenses  or  disbursements
(including reasonable fees of attorneys,  accountants,  experts and advisors) of
any kind or nature whatsoever (in this Section 11.6 collectively called "Covered
Liabilities")  which to any  extent  (in  whole or in part) may be  imposed  on,
incurred by or asserted  against the Lessor growing out of, resulting from or in
any other way associated with the Property or the Operative Documents (including
the enforcement  thereof,  whether exercised upon the Lessor's own initiative or
upon the direction of the Required Participants) and the transactions and events
at  any  time  associated  therewith  or  contemplated  therein.  The  foregoing
indemnification  shall apply whether or not such Covered  Liabilities are in any
way or to any  extent  caused,  in  whole or in part,  by any  negligent  act or
omission of any kind by the Lessor;  provided, only that no Participant shall be
obligated  under this  Section  11.6 to  indemnify  the  Lessor (i) for  Covered
Liabilities incurred in connection with any transfer or assignment by the Lessor
of its right to receive Rent or its rights and interests in and to the Property,
the  Operative  Documents or this  Agreement to its  Affiliates or (ii) for that
portion  or  percentage,  if any,  of any of the  Covered  Liabilities  which is
proximately  caused  by:  (A) the  Lessor's  own  gross  negligence  or  willful
misconduct; (B) any representation made by the Lessor in the Operative Documents
that is false in any material  respect and that the Lessor knew was false at the
time of the Lessor's execution of the Operative  Documents;  or (C) Lessor Liens
not claimed by, through or under any of the Participants. After each Participant
has paid its Percentage of any Covered  Liabilities,  each Participant  shall be
entitled  to  payment  from  the  Lessor  of an

                                      -54-
<PAGE>

amount  equal to the  Adjusted  Percentage  (as defined  below) of any  payments
subsequently  received by the Lessor as Excess  Reimbursement (as defined below)
for such  Covered  Liabilities.  As used in this Section  "Adjusted  Percentage"
shall equal (i) such Participant's  Commitment  Percentage,  divided by (ii) the
sum of the Commitment  Percentages of all  Participants who have paid the Lessor
their  respective  shares of the Covered  Liabilities at issue.  As used in this
Section, the term "Excess Reimbursement" shall mean, for the Covered Liabilities
at issue, amounts reimbursed or paid by the Lessee to or on behalf of the Lessor
on  account  of  such  Covered   Liabilities  in  excess  of  (i)  such  Covered
Liabilities, times (ii) the Commitment Percentages of any Participants that have
not paid the Lessor their respective Percentages of such Covered Liabilities.

         SECTION 11.7.  Required  Supplemental  Payments.  In the event that the
Lessee fails to pay any  Required  Supplemental  Payment when due (a  "Defaulted
Amount"),  the Lessor shall notify each  Participant of such  Defaulted  Amount,
whereupon  each  Participant  shall pay to the  Lessor  an amount  equal to such
Participant's  Commitment  Percentage times the Defaulted  Amount;  such payment
from  Participant  to the Lessor shall be due prior to 2:00 p.m.,  San Francisco
time,  on the date of such  notice if such  notice is given by 12:00  noon,  San
Francisco  time,  otherwise prior to 12:00 noon, San Francisco time, on the next
Business Day following such notice. After payment of a Participant's  Commitment
Percentage times the Defaulted Amount, any payments subsequently received by the
Lessor  from the Lessee as  reimbursement  for such  Defaulted  Amount,  and any
interest  received by the Lessor from the Lessee that  accrued on the  Defaulted
Amount after the date of such Participant's payment of its Commitment Percentage
times the Defaulted  Amount,  will constitute  Supplemental Rent for purposes of
computing payments due such Participant under this Agreement.

         SECTION  11.8.   Application  of  Payments   Received  From  Defaulting
Participant As a Cure For Payment Defaults. If after a failure to make a payment
required by Section 3.4, any Defaulting Participant cures such failure, in whole
or in part,  by paying to the Lessor all or part of such  payment  and  interest
thereon at the Late  Payment  Rate,  then the Lessor shall apply the payments so
made to the Lessor,  net of the costs of collecting such payments (the "Net Cure
Proceeds"),  or  other  funds  available  to the  Lessor  equal  to the Net Cure
Proceeds, in the following order before applying the same to any other purpose:

                  (i) first,  to make payments to the Lessor itself equal to its
         Excess  Investment  (if any) until the Lessor  shall no longer have any
         Excess Investment; and

                  (ii) second, to make further Advances to the Lessee under this
         Agreement to the extent the Lessor is required or deems it  appropriate
         to do so;  provided,  that such further Advances do not cause the total
         Property Cost to exceed the sum of the Commitments.

         SECTION 11.9. Order of Application. For purposes of this Agreement, the
Lessor shall be entitled,  but not required, to apply any payments received from
the  Lessee  under the  Operative  Documents  to  satisfy  (1)  unpaid  Required
Supplemental  Payments (and interest  thereon) not included in Rent, if any, and
(2) costs  incurred  by the Lessor  because  of any sale under the Lease  before
applying such payments to satisfy the Lessee's other obligations,  regardless of
how the Lessee may have designated such payments.

         SECTION  11.10.  Investments  Pending  Dispute  Resolution;   Overnight
Investments.  Whenever the Lessor in good faith determines that it does not have
all information needed to determine how payments to Participants must be made on
account  of any then  existing  Participation  Interests  which the  Lessor  has
received,  or  whenever  the Lessor in good faith  determines  that there is any
dispute among the  Participants  about payments which must be made on account of
Participation  Interests  actually received by the Lessor, the Lessor may choose
to defer the  payments  which are the  subject of such  missing  information  or
dispute.  However,  to minimize  any such  deferral,  the Lessor  shall  attempt
diligently to obtain any missing information needed to determine how payments to
the Participants must be made. Also, pending any such deferral, or if the Lessor
is otherwise required to invest funds pending  distribution to the Participants,
the  Lessor  shall  invest  funds  equal  to (i)  the  total  of the  Commitment
Percentages of all Participants to whom payments have not been made with respect
to the  Participation  Interests at issue,  times (ii) the total  percentages at
issue.   In  addition,   the  Lessor  shall  endeavor  to  invest   payments  of
Participation Interests it receives after 12:00 noon, San Francisco time, on the
day in question  that are to be paid to a  Participant  on the next Business Day
pursuant to Section 3;  provided  that the Lessor shall have no liability to any
Participant if the Lessor is unable to make such investments. Investments by the
Lessor shall be in the overnight federal funds market pending distribution,  and
the interest earned on each dollar of principal so invested shall be paid to the
Person  entitled to receive such dollar of principal  when the principal is paid
to such Person.

         SECTION  11.11.  Agent to  Exercise  Lessor's  Rights.  The  Lessor has
assigned  its  interest  in the  Lease  to the  Agent,  for the  benefit  of the
Participants,  pursuant  to the  Assignment  of Lease.  To the  extent  provided
therein,  the  rights,  remedies,  duties  and  responsibilities  of the  Lessor
contained in this Section 11 and in the other  Operative  Documents with respect
thereto shall be  exercisable  by,  binding upon and inure to the benefit of the
Agent, for the benefit of the Participants.

         SECTION 11.12.  Exculpatory Provisions Regarding the Lessor. Subject to
the provisions of Section 11.11, each Participant hereby irrevocably  authorizes
the  Lessor to take such  actions on its  behalf as are  expressly  vested in or
delegated to the Lessor by the terms of this  Agreement and the other  Operative
Documents,  together with such powers as are reasonably  incidental thereto. The
provisions of the following  Sections of this Agreement are hereby  incorporated
by reference into this Section 11.12, substituting the word "Lessor" for "Agent"
therein:

                  (i)      Section 14.1 - second sentence.

                  (ii)     Section 14.2 - all.

                  (iii)    Section 14.3 - all.

                  (iv)     Section 14.4 - all.

                  (v)      Section 14.5 - first sentence.

                  (iv)     Section 14.6 - last sentence.

                                   SECTION 12.

                      TRANSFERS OF PARTICIPANTS' INTERESTS

         SECTION 12.1.  Restrictions on and Effect of Transfer by  Participants.
No  Participant  may (without the prior written  consent of the Agent and Lessee
(not  to  be  unreasonably  withheld))  assign,  convey  or  otherwise  transfer
(including  pursuant to a participation)  all or any portion of its right, title
or interest in, to or under its  Participation  Interest or any of the Operative
Documents or the  Property,  provided  that (x) any  Participant  may pledge its
interest  without the consent of the Agent or the Lessee to any Federal  Reserve
Bank, (y) without the prior written  consent of the Agent,  any  Participant may
transfer all or any portion of its interest to any Affiliate of such Participant
or to any other  existing  Participant  and (z) the Lessor may not  transfer its
Tranche  C  Participation  Interest  in the  absence  of an  Event  of  Default;
provided;  further,  that  in the  case  of any  transfer  (other  than  to such
Affiliate) each of the following conditions and any other applicable  conditions
of the other Operative Documents are satisfied:

                  (a)  Required  Notice  and  Effective  Date.  Any  Participant
desiring to effect a transfer of its interest  shall give written notice of each
such proposed  transfer to the Lessee,  the Agent and each other  Participant at
least five (5) Business Days prior to such proposed transfer,  setting forth the
name of such proposed  transferee,  the percentage or interest to be retained by
such  Participant,  if any,  and the date on which such  transfer is proposed to
become  effective.  All  reasonable  out-of-pocket  costs  (including,   without
limitation, legal expenses) incurred by the Lessor, the Agent or any Participant
in connection with any such disposition by a Participant under this Section 12.1
shall be borne by such  transferring  Participant.  In the  event of a  transfer
under this Section 12.1,  any expenses  incurred by the transferee in connection
with  its  review  of the  Operative  Documents  and  its  investigation  of the
transactions  contemplated  thereby  shall be borne  by such  transferee  or the
relevant Participant,  as they may determine,  but shall not be considered costs
and expenses which the Lessee is obligated to pay or reimburse  under Section 9.
Any such proposed transfer shall become effective upon the later of (i) the date
proposed in the transfer notice referred to above and (ii) the date on which all
conditions  to such  transfer  set forth in this  Section  12.1  shall have been
satisfied.

                  (b) Assumption of Obligations. Any transferee pursuant to this
Section 12.1 shall execute and deliver to the Agent and the Lessee an Assignment
and Acceptance in substantially  the form attached as Exhibit J ("Assignment and
Acceptance"), duly executed by such transferee and the transferring Participant,
and a letter in  substantially  the form of the  Participant's  Letter  attached
hereto as Exhibit K ("Participant's  Letter"),  and thereupon the obligations of
the   transferring   Participant   under  the  Operative   Documents   shall  be
proportionately  released and reduced to the extent of such  transfer.  Upon any
such transfer as above provided,  the transferee  shall be deemed to be bound by
all obligations  (whether or not yet accrued) under,  and to have become a party
to, all Operative Documents to which its transferor was a party, shall be deemed
the  pertinent  "Participant"  for all purposes of the  Operative  Documents and
shall be deemed  to have made that  portion  of the  payments  pursuant  to this
Participation  Agreement  previously  made or  deemed  to have  been made by the
transferor represented by the interest being conveyed; and each reference herein
and in the  other  Operative  Documents  to the  pertinent  "Participant"  shall
thereafter  be 

                                      -57-
<PAGE>

deemed a reference to the  transferee,  to the extent of such transfer,  for all
purposes.  Upon any such transfer,  the Agent shall deliver to each Participant,
the Lessor and the Lessee a new  Schedule I and  Schedule II to this  Agreement,
revised to reflect the relevant  information  for such new  Participant  and the
Commitment of such new Participant (and the revised Commitment of the transferor
Participant if it shall not have transferred its entire interest).

                  (c) Employee  Benefit Plans.  No Participant may make any such
assignment,  conveyance or transfer to or in connection  with any arrangement or
understanding  in any way  involving  any employee  benefit plan (or its related
trust), as defined in Section 3(3) of ERISA, or with the assets of any such plan
(or its related trust), as defined in Section 4975(e)(1) of the Code.

                  (d) Representations.  Notwithstanding anything to the contrary
set forth above, no Participant  may assign,  convey or transfer its interest to
any Person,  unless such Person shall have delivered to the Agent and the Lessee
a certificate  confirming the accuracy of the representations and warranties set
forth  in  Section  8  with   respect  to  such  Person   (other  than  as  such
representation  or warranty  relates to the  execution and delivery of Operative
Documents)  and  representing  that such Person has,  independently  and without
reliance upon the Agent,  any other  Participant or, except to the extent of the
Lessee's  representations  made under the  Operative  Documents  when made,  the
Lessee,   and  based  on  such  documents  and  information  as  it  has  deemed
appropriate,  made its own appraisal of and investigation into this transaction,
the  Property  and the  Lessee  and made its own  decision  to enter  into  this
transaction.

                  (e)  Amounts;  Agent's  Fee.  Any  transfer  of  a  Tranche  A
Participation  Interest  shall  be in a  principal  amount  which is equal to or
greater than  $2,000,000;  provided,  that no such minimum  transfer  limitation
shall be imposed  on a transfer  of a Tranche B  Participation  Interest  or, if
permitted  to be  transferred  under  Section  12.1,  a Tranche C  Participation
Interest. Each transferring Participant shall pay to the Agent a transfer fee of
$2,500.

                  (f) Applicable Law. Such transfer shall comply with Applicable
Law and shall not  require  registration  under any  securities  law  applicable
thereto.

                  (g) Effect.  From and after any transfer of its  Participation
Interest the transferring  Participant shall be released,  to the extent assumed
by the transferee,  from its liability and  obligations  hereunder and under the
other  Operative  Documents  to which such  transferor  is a party in respect of
obligations  to be  performed  on or after the date of such  transfer.  Upon any
transfer by a Participant as above provided, any such transferee shall be deemed
a "Participant"  for all purposes of such documents and each reference herein to
a Participant  shall thereafter be deemed a reference to such transferee for all
purposes to the extent of such  transfer,  except as the  context may  otherwise
require.  Notwithstanding  any  transfer as provided in this Section  12.1,  the
transferor shall be entitled to all benefits accrued and all rights vested prior
to such transfer, including, without limitation, rights to indemnification under
this Participation Agreement or any other Operative Document.

         SECTION 12.2.         Covenants and Agreements of Participants.

                  (a) Participations. Each Participant covenants and agrees that
it will not grant Participations in its Participation  Interest to any Person (a
"Sub-Participant")  unless such  participation  complies with Applicable Law and
does not require  registration  under any securities law applicable  thereto and
such  Sub-Participant  (i) is a bank or  other  financial  institution  and (ii)
represents and warrants,  in writing, to such Participant for the benefit of the
Participants, the Lessor and the Lessee that (A) no part of the funds used by it
to acquire an interest in any Participation  Interest  constitutes assets of any
"employee  benefit  plan" (as defined in Section 3(3) of ERISA) which is subject
to Title I of ERISA,  or "plan" (as defined in Section  4975(e)(1)  of the Code)
and (B) such  Sub-Participant is acquiring its interest for investment  purposes
without a view to the  distribution  thereof.  Any such Person shall require any
transferee  of  its  interest  in  its   Participation   Interest  to  make  the
representations and warranties set forth in the preceding sentence,  in writing,
to such Person for its benefit and the benefit of the  Participants,  the Lessor
and Lessee.  In the event of any such sale by a Participant  of a  participating
interest in its Participation Interest to a Sub-Participant,  such Participant's
obligations  under this  Participation  Agreement and under the other  Operative
Documents  shall  remain   unchanged,   such  Participant  shall  remain  solely
responsible  for the  performance  thereof,  such  Participant  shall remain the
holder of its Participation  Interest, for all purposes under this Participation
Agreement and under the other  Operative  Documents,  and the Lessor,  the Agent
and, except as set forth in Section  12.2(b),  the Lessee shall continue to deal
solely and directly with such Participant in connection with such  Participant's
rights and obligations  under this  Participation  Agreement and under the other
Operative Documents.

                  (b)  Transferee  Indemnities.  Each  Sub-Participant  shall be
entitled to the benefits of Sections 13.5, 13.6, and 13.7 and 13.10 with respect
to its  participation in the  Participation  Interests  outstanding from time to
time; provided that no Sub-Participant  shall be entitled to receive any greater
amount pursuant to such Sections than the transferor Participant would have been
entitled to receive in respect of the amount of the participation transferred by
such  transferor  Participant  to such  Sub-Participant  had no such transfer or
participation occurred.

         SECTION 12.3. Future Participants.  Each Participant shall be deemed to
be bound by and, upon compliance with the  requirements of this Section 12, will
be entitled  to all of the  benefits of the  provisions  of, this  Participation
Agreement.


                                   SECTION 13.

                                 INDEMNIFICATION

         SECTION 13.1. General  Indemnification.  The Lessee agrees,  whether or
not any of the transactions contemplated hereby shall be consummated,  to assume
liability for, and to indemnify,  protect,  defend,  save and keep harmless each
Indemnitee, on an After Tax Basis, from and against, any and all Claims that may
be imposed on, incurred by or asserted against such Indemnitee  (whether because
of action or  omission by such  Indemnitee  or  otherwise),  whether or not such
Indemnitee  shall also be  indemnified  as to any such Claim by any other Person
and whether or not 

                                      -59-

Lessor, the Agent or such Participant,  unless the misrepresentation was made in

the  Lessor  might be  subjected  by virtue of  entering  into the  transactions
contemplated by this Participation Agreement;

                  (g)  the  existence  of any  Lien on or  with  respect  to the
Property, the Improvements,  the Equipment, any Basic Rent or Supplemental Rent,
title thereto,  or any interest  therein  including any Liens which arise out of
the  possession,  use,  occupancy,  construction,  repair or  rebuilding  of the
Property or by reason of labor or  materials  furnished  or claimed to have been
furnished  to the  Lessee,  the  Existing  Owner,  the  Lessor  or any of  their

provided,  however, the Lessee shall not be required to indemnify (x) the Lessor
for any Claim to the extent  arising  from any  misrepresentation  by the Lessor
under  Section  8.1 (e) or (l) or from the  failure by the Lessor to comply with
Section 10.3 (a), or (y) any  Indemnitee  under this Section 13.1 for any of the
following:  (1) any Claim to the extent resulting from the willful misconduct or
gross  negligence  of such  Indemnitee or its agents,  employees or  contractors
(other  than the Lessee and its  agents,  employers  or  contractors)  (it being
understood  that the Lessee shall be required to indemnify an Indemnitee even if
the ordinary (but not gross) negligence of such Indemnitee caused or contributed
to such Claim),  (2) any Claim  resulting  from Lessor Liens which the Lessor is
responsible for discharging under the Operative Documents,  (3) any Claim to the
extent attributable to acts or events occurring after the expiration of the Term
or the  termination  of the  Lessee's  right to possess and control the Property

to or during  the Term or  occurring  at any time  that the  Lessee is in actual
possession or control of the  Property),  (4) any Imposition or other claims for
Taxes,  and (5) any Claims of the type(s)  described in Sections 13.2 (only with

exercise of the Remarketing Option), 13.6, 13.7, 13.8 and 13.10. It is expressly
understood  and agreed that the indemnity  provided for herein shall survive the
expiration  or  termination  of and shall be separate and  independent  from any
remedy under the Lease or any other  Operative  Document.  Without  limiting the
express  rights of any  Indemnitee  under this Section  13.1,  this Section 13.1
shall be construed as an indemnity  only and not a guaranty of residual value of
the Property or as a guaranty of the Participation Interests.

         SECTION 13.2.         End of Term Indemnity.

                  (a) If the  Lessee  elects  the  Remarketing  Option and there
would,  after  giving  effect to the  proposed  remarketing  transactions,  be a
Shortfall  Amount,  then prior to the  Maturity  Date and as a condition  to the
Lessee's right to complete the  remarketing of the Property  pursuant to Section
22.1 of the Lease, the Lessee shall cause to be delivered to the Lessor at least
30 days prior to either the Expiration  Date or the last day of the  Remarketing
Period, if Section 17.2(h) of the Lease is applicable, at the Lessee's sole cost
and expense,  a report from an appraiser  selected by the Lessor and  reasonably
satisfactory  to the Agent and the Required  Participants  in form and substance
satisfactory to the Lessor, the Agent and the Required Participants (the "End of
the Term Report") which shall state the appraiser's conclusions as to the reason
for any  decline  in the Fair  Market  Sales  Value of the  Property  from  that
anticipated for such date in the Appraisal delivered on the Closing Date.

                  (b) Prior to the Expiration  Date, the Lessee shall pay to the
Lessor an amount (not to exceed the  Shortfall  Amount)  equal to the portion of
the Shortfall Amount that the End of the Term Report demonstrates was the result
of a decline in the Fair Market Sales Value of the Property due to:

                           (i)  extraordinary  wear and tear,  excessive  usage,
         failure to maintain,  to repair, to restore,  to rebuild or to replace,
         failure to comply with the Lease and all  applicable  laws,  failure to
         use,  workmanship,  method of  installation  or removal or maintenance,
         repair, rebuilding or replacement (excepting in each case ordinary wear
         and tear);

                            (ii) any Modification made to, or any rebuilding of,
         the Property or any part thereof by the Lessee or any sublessee; or

                            (iii)  the  existence  of  any  Hazardous  Activity,
         Hazardous Substance or Environmental Violations; or

                            (iv) any  restoration  or rebuilding  carried out by
         the Lessee or any sublessee; or

                            (v) any  condemnation of any portion of the Property
         pursuant to Article XV of the Lease; or

                            (vi) any use of the  Property or any part thereof by
         the Lessee or any  sublessee  other than as permitted by the  Operative
         Documents; or

                            (vii)  any  grant,  release,  dedication,  transfer,
         annexation or amendment made pursuant to Section 12.2 of the Lease; or

                           (viii)  the  failure  of the  Lessor to have good and
         marketable  fee  title  to the  Property  free and  clear of all  Liens
         (including Permitted Liens and Permitted  Exceptions) and exceptions to
         title, except (A) such Liens or exceptions to title that existed on the

                                      -62-
<PAGE>

         Closing  Date and  were  disclosed  in the  policy  of title  insurance
         delivered  pursuant to Section  6.1; (B) Lessor  Liens;  and (C) to the
         extent  any such  liability  arising  as a result of a title  defect is
         offset by the proceeds of title insurance.

         SECTION 13.3. Environmental Indemnity.  Without limitation of the other
provisions  of this  Section 13, the Lessee  hereby  agrees to  indemnify,  hold
harmless  and  defend  each  Indemnitee  from  and  against  any and all  claims
(including  without limitation third party claims for personal injury or real or
personal  property  damage),  losses  (including  but not limited to any loss of
value  of  the  Property),  damages,  liabilities,  fines,  penalties,  charges,
administrative and judicial  proceedings  (including  informal  proceedings) and
orders,  judgments,  remedial action,  requirements,  enforcement actions of any
kind,  and  all  reasonable  and  documented  costs  and  expenses  incurred  in
connection  therewith  (including  but not limited to reasonable  and documented
attorneys' and/or paralegals' fees and expenses), including, but not limited to,
all costs incurred in connection  with any  investigation  or monitoring of site
conditions  or any  clean-up,  remedial,  removal  or  restoration  work  by any
federal, state or local government agency, which such Indemnitee becomes subject
to because of its involvement with the Property,  the transactions  contemplated
by the Operative  Documents or any other matter  referred to in  paragraphs  (a)
through (i) of Section 13.1 arising in whole or in part, out of:

                  (a) the  presence on or under the  Property  of any  Hazardous
Substances, or any Releases or discharges of any Hazardous Substances on, under,
from or onto the Property;

                  (b) any activity, including, without limitation, construction,
carried on or undertaken on or off the Property,  and whether by the Lessee, the
Lessor, the Existing Owner or any predecessor in title or any employees, agents,
contractors or  subcontractors  of the Lessee,  the Lessor (if such activity was
undertaken  with the consent or at the  direction of the  Lessee),  the Existing
Owner  or any  predecessor  in  title,  or any  other  Persons  (including  such
Indemnitee),  in connection  with the  handling,  treatment,  removal,  storage,
decontamination, cleanup, transport or disposal of any Hazardous Substances that
at any time are  located  or  present  on or under or that at any time  migrate,
flow, percolate, diffuse or in any way move onto or under the Property;

                  (c)  loss of or  damage  to any  property  or the  environment
(including,  without limitation,  cleanup costs, response costs, remediation and
removal costs, cost of corrective action,  costs of financial  assurance,  fines
and penalties and natural resource  damages),  or death or injury to any Person,
and all expenses  associated with the protection of wildlife,  aquatic  species,
vegetation,  flora and fauna,  and any  mitigative  action  required by or under
Environmental Laws;

                  (d) any claim concerning lack of compliance with Environmental
Laws, or any act or omission  causing an  environmental  condition that requires
remediation  or would allow any  Governmental  Authority to record a Lien on the
land records;

                  (e) any residual  contamination  on or under the Property,  or
affecting any natural resources, or any contamination of any property or natural
resources  arising in connection with the generation,  use,  handling,  storage,
transport or disposal of any such  Hazardous  Substances,  and  

                                      -63-
<PAGE>

irrespective  of whether any of such  activities  were or will be  undertaken in
accordance with applicable Environmental Laws; or

                  (f)    any    material    inaccuracies,    misrepresentations,
misstatements,  and omissions and any  conflicting  information  contained in or
omitted from the Environmental Audit;

provided,  however, the Lessee shall not be required to indemnify any Indemnitee
under  this  Section  13.3 for (1) any Claim to the  extent  resulting  from the
willful  misconduct  or  gross  negligence  of such  Indemnitee  or its  agents,
employees and contractors  (other than the Lessee and its agents,  employees and
contractors) (it being understood that the Lessee shall be required to indemnify
an Indemnitee even if the ordinary (but not gross) negligence of such Indemnitee
caused or contributed to such Claim), (2) subject to the provisions Section 15.2
of the Lease,  any Claim to the extent  attributable to acts or events occurring
after the  expiration of the Term or the  termination  of the Lessee's  right to
possess and control the Property  (but not any claim to the extent  attributable
to acts or events occurring prior to or during the Term or occurring at any time
that the Lessee is in actual  possession  or control of the  Property),  (3) any
Imposition or other claims for Taxes of the type(s) described in Section 13.5 or
(4) any Claims of the type(s)  described in Sections  13.2 (only with respect to
claims in respect of a decline in the Fair Market  Sales  Value of the  Property
and the Lessee's  exercise of the  Remarketing  Option),  13.6,  13.7,  13.8 and
13.10.  It is expressly  understood  and agreed that the indemnity  provided for
herein shall survive the  expiration or termination of and shall be separate and
independent from any remedy under the Lease or any other Operative Document.

         SECTION  13.4.  Proceedings  in Respect of Claims.  With respect to any
amount that the Lessee is requested by an Indemnitee to pay by reason of Section
13.1 or 13.3, such Indemnitee  shall, if so requested by the Lessee and prior to
any payment,  submit such additional information to the Lessee as the Lessee may
reasonably  request  and  which  is in the  possession  of  such  Indemnitee  to
substantiate properly the requested payment.

         In case any action,  suit or  proceeding  shall be brought  against any
Indemnitee, such Indemnitee shall notify the Lessee of the commencement thereof,
and the Lessee shall be entitled, at its expense, to participate in, and, to the
extent  that the Lessee  desires to,  assume and  control  the defense  thereof;
provided,  however,  that the Lessee  shall  have  acknowledged  in writing  its
obligation to fully indemnify such Indemnitee in respect of such action, suit or
proceeding,  and the Lessee  shall keep such  Indemnitee  fully  apprised of the
status of such action, suit or proceeding and shall provide such Indemnitee with
all  information  with  respect  to  such  action,  suit or  proceeding  as such
Indemnitee shall reasonably request, and provided further, that the Lessee shall
not be entitled to assume and  control the defense of any such  action,  suit or
proceeding  if and to the extent  that,  (A) in the  reasonable  opinion of such
Indemnitee,  (x) such action,  suit or proceeding  involves any  possibility  of
imposition of criminal liability or any risk of material civil liability on such
Indemnitee or will involve a material  risk of the sale,  forfeiture or loss of,
or the creation of any Lien (other than
a Permitted  Exception) on the Property or any part thereof unless,  in the case
of civil  liability  or  Lien,  the  Lessee  shall  have  posted a bond or other
security  satisfactory to the relevant Indemnitee in respect to such risk or (y)
the  control  of such  action,  suit or  proceeding  would  involve an actual or
potential  conflict of interest,  (B) such proceeding  involves Claims not fully
indemnified

                                      -64-
<PAGE>


by the Lessee which the Lessee and the Indemnitee have been unable to sever from
the  indemnified  claim(s),  or (C) an Event of  Default  under  the  Lease  has
occurred and is  continuing.  The  Indemnitee  may  participate  in a reasonable
manner at its own expense and with its own counsel in any  proceeding  conducted
by the Lessee in accordance with the foregoing.  The Lessee shall not enter into
any settlement or other  compromise  with respect to any Claim which is entitled
to be indemnified  under Section 13.1 or 13.3 without the prior written  consent
of the Indemnitee  which consent shall not be unreasonably  withheld in the case
of  a  money  settlement  not  involving  an  admission  of  liability  of  such
Indemnitee.

         Each Indemnitee  shall at the expense of the Lessee  cooperate with and
supply the Lessee with such  information and documents  reasonably  requested by
the Lessee as are  necessary or advisable for the Lessee to  participate  in any
action,  suit or  proceeding  to the extent  permitted  by Section 13.1 or 13.3.
Unless  an  Event  of  Default  under  the  Lease  shall  have  occurred  and be
continuing,  no Indemnitee  shall enter into any settlement or other  compromise
with respect to any Claim which is entitled to be indemnified under Section 13.1
or 13.3 without the prior written consent of the Lessee, which consent shall not
be  unreasonably  withheld,  unless  such  Indemnitee  waives  its  right  to be
indemnified under Section 13.1 or 13.3 with respect to such Claim.

         Upon  payment  in full of any Claim by the Lessee  pursuant  to Section
13.1 or 13.3 to or on behalf of an Indemnitee,  the Lessee,  without any further
action,  shall be subrogated to any and all claims that such Indemnitee may have
relating thereto (other than claims in respect of insurance policies  maintained
by such Indemnitee at its own expense),  and such Indemnitee  shall execute such
instruments  of assignment  and  conveyance,  evidence of claims and payment and
such other documents, instruments and agreements as may be necessary to preserve
any such claims and  otherwise  cooperate  with the Lessee and give such further
assurances  as are  necessary or advisable  to enable the Lessee  vigorously  to
pursue such claims.

         Any amount  payable to an  Indemnitee  pursuant to Section 13.1 or 13.3
shall be paid to such  Indemnitee  promptly  upon  receipt  of a written  demand
therefor from such Indemnitee,  accompanied by a written statement describing in
reasonable detail the basis for such indemnity and the computation of the amount
so payable and, if requested by the Lessee, such determination shall be verified
by a nationally  recognized  independent  accounting firm mutually acceptable to
the Lessee and the Indemnitee at the expense of the Lessee.

         SECTION 13.5.         General Impositions Indemnity.

                  (a) Indemnification. The Lessee shall pay and assume liability
for, and does hereby agree to indemnify, protect and defend the Property and all
Indemnitees,  and hold them harmless  against,  all  Impositions on an After Tax
Basis.

                  (b) Payments. (i) Subject to the terms of Section 13.5(f), the
Lessee  shall pay or cause to be paid all  Impositions  directly  to the  taxing
authorities where feasible and otherwise to the Indemnitee, as appropriate,  and
the Lessee shall at its own expense, upon such Indemnitee's  reasonable request,
furnish to such  Indemnitee  copies of official  receipts or other  satisfactory
proof evidencing such payment.

                                      -65-
<PAGE>

                           (ii) In the case of Impositions  for which no contest
is conducted  pursuant to Section  13.5(f) and which the Lessee pays directly to
the taxing  authorities,  the  Lessee  shall pay such  Impositions  prior to the
latest time permitted by the relevant taxing  authority for timely  payment.  In
the case of  Impositions  for which the Lessee  reimburses  an  Indemnitee,  the
Lessee shall do so within twenty (20) days after receipt by the Lessee of demand
by such Indemnitee  describing in reasonable detail the nature of the Imposition
and the basis for the demand  (including the computation of the amount payable),
but in no event shall the Lessee be required to pay such reimbursement  prior to
ten (10) days before the latest time permitted by the relevant taxing  authority
for timely payment.  In the case of Impositions for which a contest is conducted
pursuant to Section 13.5(f),  the Lessee shall pay such Impositions or reimburse
such  Indemnitee  for such  Impositions,  to the extent not  previously  paid or
reimbursed pursuant to subsection (a), prior to the latest time permitted by the
relevant  taxing  authority for timely payment after  conclusion of all contests
under Section 13.5(f).

                           (iii) At the  Lessee's  request,  the  amount  of any
indemnification  payment  by the  Lessee  pursuant  to  subsection  (a) shall be
verified  and  certified  by an  independent  public  accounting  firm  mutually
acceptable  to the  Lessee and the  Indemnitee.  The fees and  expenses  of such
independent  public  accounting  firm  shall be paid by the Lessee  unless  such
verification  shall result in an adjustment in the Lessee's  favor of 5% or more
of the payment as computed  by the  Indemnitee,  in which case such fee shall be
paid by the Indemnitee.

                  (c) Reports and Returns.  (i) The Lessee shall be  responsible
for  preparing  and  filing any real and  personal  property  or ad valorem  tax
returns in respect of the Property. In case any other report or tax return shall
be required to be made with  respect to any  obligations  of the Lessee under or
arising out of  subsection  (a) and of which the Lessee has  knowledge or should
have  knowledge,  the Lessee,  at its sole cost and  expense,  shall  notify the
relevant  Indemnitee of such requirement and (except if such Indemnitee notifies
the Lessee  that such  Indemnitee  intends to file such report or return) (A) to
the extent required or permitted by and consistent with Applicable Law, make and
file in its own name such return,  statement  or report;  and (B) in the case of
any other such return,  statement  or report  required to be made in the name of
such  Indemnitee,  advise such  Indemnitee of such fact and prepare such return,
statement  or report  for  filing by such  Indemnitee  or,  where  such  return,
statement  or report  shall be  required  to reflect  items in  addition  to any
obligations of the Lessee under or arising out of subsection  (a),  provide such
Indemnitee at the Lessee's  expense with  information  sufficient to permit such
return,  statement or report to be properly made with respect to any obligations
of the Lessee under or arising out of  subsection  (a). Such  Indemnitee  shall,
upon  the  Lessee's  request  and at the  Lessee's  expense,  provide  any  data
maintained  by such  Indemnitee  (and not  otherwise  available to or within the
control  of the  Lessee)  with  respect  to the  Property  which the  Lessee may
reasonably  require  to prepare  any  required  tax  returns  or  reports.  Each
Indemnitee  agrees to use its best  efforts  to send to the Lessee a copy of any
written request or other notice that the Indemnitee receives with respect to any
reports or returns  required  to be filed with  respect to the  Property  or the
transactions  contemplated by the Operative Documents,  it being understood that
no Indemnitee shall have any liability for failure to provide such copies.

                  (d)  Income  Inclusions.  If as a  result  of the  payment  or
reimbursement  by the Lessee of any expenses of the Lessor or the payment of any
Transaction  Expenses incurred in connection with the transactions  contemplated
by the Operative  Documents,  the Lessor or any  Participant  shall suffer a net
increase in any federal,  state or local income tax liability,  the Lessee shall
indemnify such Persons (without  duplication of any indemnification  required by
subsection  (a)) on an After  Tax Basis for the  amount  of such  increase.  The
calculation  of any such net  increase  shall take into  account  any current or
future tax savings realized or reasonably expected to be realized by such person
in respect  thereof,  as well as any  interest,  penalties  and additions to tax
payable by the Lessor, or any Participant or such Affiliate, in respect thereof.

                  (e) Withholding  Taxes. As between the Lessee on one hand, and
the Lessor or the Agent and any  Participant on the other hand, the Lessee shall
be responsible  for, and, subject to the provisions of Sections 13.5(g) and (h),
the Lessee  shall  indemnify  and hold  harmless  the Lessor,  the Agent and the
Participants (without duplication of any indemnification  required by subsection
(a)) on an After Tax Basis against,  any obligation for United States or foreign
withholding   taxes   imposed  in  respect  of  payments  with  respect  to  the
Participation  Interests  or with  respect to Rent  payments  under the Lease or
payments of the Asset  Termination  Value or Purchase  Option Price (and, if the
Lessor, the Agent or any Participant receives a demand for such payment from any
taxing  authority,  the  Lessee  shall  discharge  such  demand on behalf of the
Lessor, the Agent or such Participant). Notwithstanding the foregoing provisions
of this Section 13.5(e) or any other provision of any Operative  Document to the
contrary,  the Lessee shall not be responsible  for and shall not be required to
indemnify or otherwise hold harmless any Person from or against any  withholding
tax  imposed as a  collection  device  for,  or in  substitution  or lieu of, an
income, franchise or similar tax to the extent such income, franchise or similar
tax would not otherwise be subject to  indemnification  pursuant to this Section
13.5 (a "Qualified  Withholding  Tax").  As used herein,  Qualified  Withholding
Taxes include,  without limitation,  any withholding taxes arising under Section
871,  881,  1441 or 1442 of the Code and any similar  taxes arising under state,
local or foreign  law as well as any  withholding  tax  imposed as a  collection
device for, or in  substitution  or lieu of the Imposition  that qualifies as an
"income tax" within the meaning of United  States  Treasury  Regulation  Section
1.901-2.

                  (f) Contests of  Impositions.  (i) If a written  claim is made
against any  Indemnitee  or if any  proceeding  shall be commenced  against such
Indemnitee (including a written notice of such proceeding), for any Impositions,
such  Indemnitee  shall promptly notify the Lessee in writing and shall not take
action  with  respect to such claim or  proceeding  without  the  consent of the
Lessee for  thirty  (30) days after the  receipt of such  notice by the  Lessee;
provided,  however, that, in the case of any such claim or proceeding, if action
shall be  required  by law or  regulation  to be taken  prior to the end of such
30-day period,  such Indemnitee shall, in such notice to the Lessee,  inform the
Lessee of such shorter period, and no action shall be taken with respect to such
claim or  proceeding  without the consent of the Lessee before 2 days before the
end of  such  shorter  period;  provided,  further,  that  the  failure  of such
Indemnitee to give the notices  referred to this sentence shall not diminish the
Lessee's  obligation  hereunder except to the extent such failure  precludes the
Lessee from contesting all or part of such claim.


                                      -67-
<PAGE>

                           (ii) If,  within  thirty (30) days of receipt of such
notice  from the  Indemnitee  (or such  shorter  period  as the  Indemnitee  has
notified  the Lessee is  required by law or  regulation  for the  Indemnitee  to
commence such contest), the Lessee shall request in writing that such Indemnitee
contest such Imposition,  the Indemnitee shall, at the expense of the Lessee, in
good faith conduct and control such contest (including,  without limitation,  by
pursuit of appeals)  relating to the validity,  applicability  or amount of such
Impositions  (provided,  however,  that (A) if such contest involves a tax other
than a tax on net  income  and  can be  pursued  independently  from  any  other
proceeding  involving an  unindemnified  tax liability of such  Indemnitee,  the
Indemnitee,  at the  Lessee's  request,  shall  allow the Lessee to conduct  and
control  such  contest and (B) in the case of any contest,  the  Indemnitee  may
request  the  Lessee  to  conduct  and  control  such  contest)  by, in the sole
discretion of the Person conducting and controlling such contest,  (1) resisting
payment  thereof,  (2) not paying the same except under  protest,  if protest is
necessary and proper,  (3) if the payment be made, using  reasonable  efforts to
obtain a refund thereof in appropriate  administrative and judicial proceedings,
or (4) taking such other  action as is  reasonably  requested by the Lessee from
time to time.

                           (iii) The party controlling any contest shall consult
in good faith with the non-controlling  party and shall keep the non-controlling
party reasonably informed as to the conduct of such contest;  provided, that all
decisions  ultimately  shall be made in the sole  discretion of the  controlling
party  except that no  decision  shall be made to concede an  indemnified  issue
without the prior  consent of Lessee (which  consent  shall not be  unreasonably
withheld).  The parties agree that an Indemnitee may at any time decline to take
further action with respect to the contest of any Imposition and may settle such
contest if such  Indemnitee  shall  waive its rights to any  indemnity  from the
Lessee that otherwise  would be payable in respect of such claim (and any future
claim by any taxing  authority,  the contest of which is  precluded by reason of
such resolution of such claim) and shall pay to the Lessee any amount previously
paid  or  advanced  by the  Lessee  pursuant  to  this  Section  13.5  by way of
indemnification  or advance for the payment of an Imposition other than expenses
of such contest.

                           (iv) Notwithstanding the foregoing provisions of this
Section  13.5,  an  Indemnitee  shall not be required to take any action and the
Lessee shall not be permitted to contest any Impositions in its own name or that
of the  Indemnitee  unless (A) the Lessee shall have agreed such  Imposition  is
subject to indemnity hereunder and shall pay to such Indemnitee on demand and on
an After  Tax  Basis  all  reasonable  costs,  losses  and  expenses  that  such
Indemnitee  actually  incurs in connection  with  contesting  such  Impositions,
including,   without   limitation,   all   reasonable   legal,   accounting  and
investigatory  fees and  disbursements,  (B) in the case of a claim that must be
pursued in the name of an Indemnitee  (or an Affiliate  thereof),  the amount of
the potential  indemnity  (taking into account all similar or logically  related
claims that have been or could be raised in any audit  involving such Indemnitee
for which the Lessee may be liable to pay an indemnity  under this Section 13.5)
exceeds $10,000,  (C) the Indemnitee  shall have reasonably  determined that the
action to be taken will not result in any material danger of sale, forfeiture or
loss of the  Property,  or any  part  thereof  or  interest  therein,  will  not
interfere  with the  payment of Rent,  and will not  result in risk of  criminal
liability, (D) if such contest shall involve the payment of the Imposition prior
to the contest,  the Lessee shall  provide to the  Indemnitee  an  interest-free
advance in an amount equal to the Imposition  that the Indemnitee is required to
pay (with no additional net after-tax cost to such Indemnitee),  (E) in the case
of a claim that must be pursued in the name of an  Indemnitee  (or an

Affiliate thereof), the Lessee shall have provided to such Indemnitee an opinion
of   independent   tax  counsel   selected  by  the  Indemnitee  and  reasonably
satisfactory  to the Lessee  stating that a  reasonable  basis exists to contest
such claim (or, in the case of an appeal of an adverse  judicial  determination,
an opinion of such counsel to the effect that there is substantial authority for
the  position  asserted in such  appeal)  and (F) no Event of Default  hereunder
shall have  occurred  and be  continuing.  In no event  shall an  Indemnitee  be
required  to appeal an  adverse  judicial  determination  to the  United  States
Supreme Court. In addition,  an Indemnitee  shall not be required to contest any
claim in its name (or that of an Affiliate) if the subject  matter thereof shall
be of a continuing  nature and shall have previously been decided adversely by a
court of competent  jurisdiction  pursuant to a contest  completed in accordance
with the provisions of this Section 13.5,  unless there shall have been a change
in law (or  interpretation  thereof) and the Indemnitee shall have received,  at
the Lessee's  expense,  an opinion of  independent  tax counsel  selected by the
Indemnitee and  reasonably  acceptable to the Lessee stating that as a result of
such change in law (or interpretation  thereof), it is more likely than not that
the Indemnitee will prevail in such contest.

                  (g) Documentation of Withholding  Status. Each Participant (or
any successor thereto or transferee thereof) that is organized under the laws of
a  jurisdiction  outside of the United States of America and each Lessor that is
organized  under the laws of a  jurisdiction  outside  of the  United  States of
America shall:

                           (i) on or before  the date it  becomes a party to any
                  Operative  Document,  deliver to the Lessee any  certificates,
                  documents,  or other  evidence  that shall be  required by the
                  Code  or  Treasury  Regulations  issued  pursuant  thereto  to
                  establish its exemption from United States Federal withholding
                  requirements,   including  (A)  two  valid,   duly  completed,
                  original copies of Internal  Revenue Service Form 1001 or Form
                  4224 or successor applicable form, properly and duly executed,
                  certifying in each case that such party is entitled to receive
                  payments pursuant to the Operative Documents without deduction
                  or withholding of United States Federal income taxes, or (B) a
                  valid,  duly  completed,  original  copy of  Internal  Revenue
                  Service  Form W-8 or Form W-9 or  applicable  successor  form,
                  properly  and duly  executed,  certifying  that such  party is
                  entitled to an exemption  from United States of America backup
                  withholding tax; and

                        (ii) so long as it shall be legally  entitled  to do so,
                  on or  before  the date  that any such  form  described  above
                  expires or becomes  obsolete,  or after the  occurrence of any
                  event  requiring  a  change  in  the  most  recent  such  form
                  previously delivered to the Lessee,  deliver to the Lessee two
                  further valid,  duly  completed,  original  copies of any such
                  form or certification, properly and duly executed.

                  (h) Limitation on Tax Indemnification. The Lessee shall not be
required to indemnify any  Indemnitee,  or to pay any  increased  amounts to any
Indemnitee or tax  authority  with respect to any  Impositions  pursuant to this
Section  13.5 to the extent that (i) such  Imposition  is  attributable  to such
Indemnitee's  failure to comply with the provisions of Section 13.5(g);  or (ii)
to the  extent  such  Imposition  constitutes  or is  collected  by  means  of a
Qualified Withholding Tax.

                                      -69-
<PAGE>


                  (i) Tax Savings.  In the event an Indemnitee receives a refund
(or similar tax savings) in respect of any Imposition  paid or reimbursed by the
Lessee which was not considered in calculating  the After Tax Basis with respect
to such payment or reimbursement by Lessee,  such Indemnitee shall within thirty
(30) days  thereafter  remit the amount of such  refund (or tax  savings) to the
Lessee, provided that the amount so remitted shall not exceed the lesser of: (i)
the amount  received by such  Indemnitee as a refund (or tax savings) net of all
reasonable  costs and expenses  incurred by such  Indemnitee in connection  with
obtaining and paying such amount;  and (ii) (a) the amount of all prior payments
by the Lessee to such Indemnitee with respect to Impositions,  plus any refunded
interest,  less (b) the amount of all prior  payments by the  Indemnitee  to the
Lessee under this Section 13.5(i).

         SECTION  13.6.  Funding  Losses.  If any  payment of any Advance or any
portion of any Participation Interest is made on any day other than the last day
of an Interest Period applicable  thereto, or if the Lessee fails to utilize the
proceeds of any purchase of Participation  Interests after notice has been given
to any Participant in accordance with Section 3 or 4, the Lessee shall reimburse
each  Participant  within  fifteen (15) days after demand for any Funding Losses
provided that such Participant  shall have delivered to the Lessee a certificate
as to the amount of such loss or expense,  which certificate shall be conclusive
in the absence of manifest error,  and provided  further that such loss shall in
no event exceed the  interest on the Advances  which would have been payable for
the balance of such Interest  Period or other period,  less the amount  actually
earned by such  Participant  on such  Advances.  Such  Participant  will, at the
request of the  Lessee,  furnish  such  additional  information  concerning  the
determination of such loss as the Lessee may reasonably request.

         SECTION 13.7. Regulation D Compensation. For so long as any Participant
is required by a Change of Law to increase its existing reserve percentage above
that   applicable   under   existing  law  as  of  the  Effective  Date  against
"Eurocurrency  Liabilities" (or any other category of liabilities  which include
deposits by reference to which the interest rate on its  Participation  Interest
in any Advance is  determined  or any category of  extensions of credit or other
assets which includes loans by a non-United States office of such Participant to
United States residents), and, as a result, the cost to such Participant (or its
Funding Office) of purchasing or maintaining its  Participation  Interest in any
Advance is  increased,  then such  Participant  may  require  the Lessee to pay,
contemporaneously  with each  payment of  interest  or Yield on the  Advances an
additional  amount on the  Participation  Interest  of such  Participant  in the
Advances at a rate per annum up to but not  exceeding  the excess of (i) (A) the
applicable  Eurodollar  Rate divided by (B) one minus the  Eurocurrency  Reserve
Requirements and (ii) the applicable Eurodollar Rate. Any Participant wishing to
require payment of such additional amount (x) shall so notify the Lessee and the
Agent, in which case such additional  interest on its Participation  Interest in
any Advance shall be payable to such  Participant at the place indicated in such
notice  with  respect to each  Interest  Period  commencing  at least  three (3)
Business  Days  after the  giving of such  notice  and (y) shall  furnish to the
Lessee at least five (5) Business  Days prior to each date on which  interest is
payable on the  Advance an  officer's  certificate  setting  forth the amount to
which such  Participant  is then  entitled  under this  Section  (which shall be
consistent with such Participant's good faith estimate of the level at which the
related  reserves  are  maintained  by  it).  Each  such  certificate  shall  be
accompanied by such  information as the Lessee may reasonably  request as to the
computation set forth therein.

         SECTION 13.8. Basis for Determining Interest Rate Inadequate or Unfair.
If on or prior to the first day of any Interest Period:

                  (a)  deposits in dollars (in the  applicable  amounts) are not
being offered to the Agent in the relevant  market for such  Interest  Period or
any  Participants  shall advise the Agent that the Eurodollar Rate as determined
by the Agent will not adequately and fairly reflect the cost to such Participant
of funding its  Participation  Interest in any Advance for such Interest Period;
or

                  (b)  any  Participant   determines  that,  by  reason  of  the
adoption,  on or  after  the  date  of  this  Participation  Agreement,  of  any
applicable law, rule or regulation,  or any change therein, or any change in the
interpretation or administration thereof by any Governmental Authority,  central
bank or comparable  agency  charged with the  interpretation  or  administration
thereof,  or  compliance  by any  Participant  (or its Funding  Office) with any
request  or  directive  (whether  or not  having  the  force of law) of any such
authority,  central bank or governmental  agency, it is restricted,  directly or
indirectly,  in the amount it may hold of (i) a  category  of  liabilities  that
includes  deposits by reference to which, or on the basis of which, the interest
rates applicable to Advances to fund its Participation Interest Commitment based
on the  Eurodollar  Rate are  directly  or  indirectly  determined,  or (ii) the
category of assets which includes  Advances to fund its  Participation  Interest
Commitment based on the Eurodollar Rate;

the  Agent  shall   forthwith   give  notice  thereof  to  the  Lessee  and  the
Participants,   whereupon   until  the  Agent   notifies  the  Lessee  that  the
circumstances  giving rise to such suspension no longer exist,  each outstanding
Advance  shall  begin to bear  interest  on the  last  day of the  then  current
Interest Period  applicable  thereto at a rate per annum equal to the sum of (i)
the  Participants'  average cost of funds  employed to fund their  Participation
Interests,  as notified to the Agent and the  Lessee,  plus (ii) the  Applicable
Margin for Eurodollar Rate-based Advances at such time.

         SECTION   13.9.   Illegality.   If,  on  or  after  the  date  of  this
Participation Agreement, the adoption of any applicable law, rule or regulation,
or any change therein,  or any change in the  interpretation  or  administration
thereof by any Governmental Authority, central bank or comparable agency charged
with  the  interpretation  or  administration  thereof,  or  compliance  by  any
Participant  (or its Funding  Office) with any request or directive  (whether or
not having the force of law) of any such  authority,  central bank or comparable
agency (a  "Charge  of Law"),  shall  make it  unlawful  or  impossible  for any
Participant  (or  its  Funding  Office)  to  purchase,   maintain  or  fund  its
Participation  Interest in any Advance and such Participant  shall so notify the
Agent,  the Agent shall forthwith give notice thereof to the other  Participants
and the Lessee,  whereupon  until such  Participant  notifies the Lessee and the
Agent that the circumstances giving rise to such suspension no longer exist, the
obligation of such  Participant  to purchase its  Participation  Interest in any
Advance  shall be suspended.  Before giving any notice to the Agent  pursuant to
this Section,  such Participant  shall, if practicable,  with the consent of the
Lessee (which consent shall not unreasonably be withheld), designate a different
Funding  Office if such  designation  will avoid the need for giving such notice
and will not, in the judgment of such Participant,  be otherwise disadvantageous
to such  Participant.  If such notice is given (i) the Lessee  shall be entitled
upon its request to a  reasonable  explanation  of the factors  underlying  such
notice and (ii) each outstanding  Participation  Interest in any Advance of such
Participant then outstanding  shall begin to bear interest at the Alternate Base
Rate either (a)

                                      -71-
<PAGE>

on the last day of the then current  Interest Period  applicable to such Advance
if  such   Participant   may  lawfully   continue  to  maintain  and  fund  such
Participation  Interest to such day or (b) immediately if such Participant shall
determine  that  it  may  not  lawfully  continue  to  maintain  and  fund  such
Participation  Interest  to such day.  If such  notice is given the  Lessee  may
exercise its Purchase  Option under Section 20.1 of the Lease upon not less than
ten (10) days' written notice to the Lessor, the Agent and the Participants.

         SECTION 13.10. Increased Cost and Reduced Return. (a) In the event that
the adoption of any applicable law, rule or regulation, or any change therein or
in the  interpretation  or application  thereof by any  Governmental  Authority,
central  bank  or  comparable   agency  charged  with  the   interpretation   or
administration  thereof or  compliance  by any  Participant  with any request or
directive  after the date hereof (whether or not having the force of law) of any
such authority, central bank or comparable agency:

                           (i) does or shall  subject  such  Participant  to any
         additional  tax of any kind  whatsoever  with respect to the  Operative
         Documents or any purchase of a  Participation  Interest in any Advance,
         or change the basis or the  applicable  rate of taxation of payments to
         such  Participant  of its  Participation  Interest or any other  amount
         payable  hereunder  (except for the  imposition of or change in (x) any
         tax on or  measured  by the  overall  net  income  of such  Participant
         including,  without  limitation,  any tax that  qualifies as an "income
         tax" within the meaning of United States  Treasury  Regulation  Section
         1.901-2 and which is not an Imposition or (y) any Qualified Withholding
         Tax);

                           (ii) does or shall impose,  modify or hold applicable
         any reserve, special deposit, insurance assessment,  compulsory loan or
         similar  requirement  against  assets  held by,  or  deposits  or other
         liabilities  in or for the account  of,  advances or loans by, or other
         credit extended by, or any other acquisition of funds by, any office of
         such Participant  which are not otherwise  included in determination of
         the rate of interest on Advances hereunder; or

                           (iii) does or shall  impose on such  Participant  any
         other condition;

and  the  result  of any of the  foregoing  is to  increase  the  cost  to  such
Participant  of  purchasing or  maintaining  its  Participation  Interest in any
Advance or to reduce any amount receivable hereunder with respect thereto,  then
in any such case,  the Lessee  shall  promptly  pay such  Participant,  upon its
demand, any additional amounts necessary to compensate such Participant for such
increased cost or reduced amount  receivable which such Participant  deems to be
material as determined by such Participant  provided,  however,  that the Lessee
shall not be obligated to pay any  Participant  for any such increased  costs or
reduced  amounts  incurred  more than  sixty (60) days prior to the date of such
Participant's  demand for  payment if such  demand was made more than sixty (60)
days after the latest of (A) the date such Participant received actual notice of
such increased cost or reduced amount,  (B) the effective date of such change or
(C) the date such change occurred or was enacted.

                  (b) If any Participant  shall have determined  that, after the
date hereof,  the adoption of any applicable  law, rule or regulation  regarding
capital adequacy,  or any change therein,

                                      -72-
<PAGE>

or  any  change  in  the   interpretation  or  administration   thereof  by  any
Governmental  Authority,  central  bank or  comparable  agency  charged with the
interpretation or administration  thereof, or any request or directive regarding
capital adequacy (whether or not having the force of law) of any such authority,
central bank or  comparable  agency has or would have the effect of reducing the
rate of return  on  capital  of such  Participant  (or any  entity  directly  or
indirectly  controlling such Participant) as a consequence of such Participant's
obligations  under the  Operative  Documents  to a level  below  that which such
Participant (or any entity directly or indirectly  controlling such Participant)
could have achieved but for such adoption,  change, request or directive (taking
into  consideration  its policies with respect to capital adequacy) by an amount
deemed by such  Participant  to be material,  then from time to time,  within 15
days after  demand by such  Participant  (with a copy to the Agent),  the Lessee
shall  pay to  such  Participant  such  additional  amount  or  amounts  as will
compensate such Participant (or its parent) for such reduction.

                  (c) Each  Participant  will promptly notify the Lessee and the
Agent of any event of which it has knowledge,  occurring  after the date hereof,
which will entitle such Participant to compensation pursuant to this Section and
will, if  practicable,  with the consent of the Lessee (which  consent shall not
unreasonably  be  withheld),  designate a different  Funding  Office or take any
other  reasonable  action if such designation or action will avoid the need for,
or reduce the amount of, such compensation and will not, in the judgment of such
Participant,  be otherwise disadvantageous to such Participant. A certificate of
any Participant  claiming  compensation  under this Section and setting forth in
reasonable detail its computation of the additional amount or amounts to be paid
to it  hereunder  shall be  conclusive  in the  absence of  manifest  error.  In
determining such amount,  such Participant may use any reasonable  averaging and
attribution  methods.  This  Section  shall  survive  the  termination  of  this
Participation   Agreement   and  payment  of  the   outstanding   Advances   and
Participation Interests.

         SECTION 13.11.  Substitution of  Participant.  If (i) the obligation of
any  Participant  to purchase or maintain  its  Participation  Interest has been
suspended  pursuant to this  Section 13, or (ii) any  Participant  has  demanded
compensation  or given  notice of its  intention  to demand  compensation  under
Sections 13.1,  13.2, 13.5 or 13.10,  the Lessee shall have the right,  with the
assistance of the Agent,  to seek one or more mutually  satisfactory  substitute
banks or financial  institutions  (which may be one or more of the Participants)
to replace such Participant under the Operative Documents.

         SECTION  13.12.  Indemnity  Payments  in  Addition  to  Residual  Value
Guarantee  Amount.  The Lessee  acknowledges  and agrees that its obligations to
make indemnity payments under this Section 13 are separate from, in addition to,
and do not reduce,  its  obligation to pay the Residual Value  Guarantee  Amount
under the Lease;  provided,  that except as otherwise  set forth in Section 13.2
hereof,  the  Shortfall  Amount  payable  by the Lessee in  connection  with the
Remarketing Option under the Lease shall not be increased under this Section 13.

                                   SECTION 14.

                                    THE AGENT

         SECTION  14.1.   Appointment.   Each  Participant   hereby  irrevocably
designates  and  appoints  the  Agent as the  agent of such  Lender  under  this
Agreement and the other Operative  Documents,  and each Participant  irrevocably
authorizes the Agent, in such capacity,  to take such action on its behalf under
the  provisions  of this  Agreement  and the other  Operative  Documents  and to
exercise such powers and perform such duties as are  expressly  delegated to the
Agent by the terms of this Agreement and the other Operative Documents, together
with such other powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere in this Agreement,  the Agent shall not have
any duties or responsibilities,  except those expressly set forth herein, or any
fiduciary  relationship with any Participant or any other party to the Operative
Documents,  and  no  implied  covenants,  functions,  responsibilities,  duties,
obligations  or  liabilities  shall be read  into  this  Agreement  or any other
Operative Document or otherwise exist against the Agent.

         SECTION 14.2.  Delegation  of Duties.  The Agent may execute any of its
duties  under this  Agreement  and the other  Operative  Documents by or through
agents  or  attorneys-in-fact  and  shall  be  entitled  to  advice  of  counsel
concerning  all  matters  pertaining  to such  duties.  The  Agent  shall not be
responsible for the negligence or misconduct of any agents or  attorneys-in-fact
selected by it with reasonable care.

         SECTION 14.3. Exculpatory Provisions.  Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(a) liable for any  action  lawfully  taken or omitted to be taken by it or such
Person  under or in  connection  with  this  Agreement  or any  other  Operative
Document  (except  for its or such  Person's  own gross  negligence  or  willful
misconduct) or (b)  responsible in any manner to any of the  Participants or any
other  party  to  the  Operative   Documents   for  any  recitals,   statements,
representations  or  warranties  made by the Lessor or the Lessee or any officer
thereof  contained in this Agreement or any other  Operative  Document or in any
certificate, report, statement or other document referred to or provided for in,
or received by the Agent under or in  connection  with,  this  Agreement  or any
other Operative Document or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or any other Operative  Document
or for any  failure  of the  Lessor or the  Lessee to  perform  its  obligations
hereunder  or  thereunder.  The Agent shall not be under any  obligation  to any
Participant  or any other party to the  Operative  Documents  to ascertain or to
inquire as to the observance or  performance of any of the agreements  contained
in, or conditions  of, this  Agreement or any other  Operative  Document,  or to
inspect the properties, books or records of the Lessor or the Lessee.

         SECTION 14.4.  Reliance by Agent.  The Agent shall be entitled to rely,
and shall be fully protected in relying, upon any writing,  resolution,  notice,
consent,  certificate,  affidavit,  letter, telecopy, telex or teletype message,
statement,  order or other document or conversation believed by it to be genuine
and  correct  and to have  been  signed,  sent or made by the  proper  Person or
Persons and upon advice and  statements  of legal  counsel  (including,  without
limitation,  counsel to the Lessor 

                                      -74-
<PAGE>

or the Lessee), independent accountants and other experts selected by the Agent.
The Agent  shall be fully  justified  in failing or  refusing to take any action
under this  Agreement  or any other  Operative  Document  unless it shall  first
receive  such advice or  concurrence  of the Required  Participants  as it deems
appropriate  or it  shall  first  be  indemnified  to  its  satisfaction  by the
Participants  against any and all liability and expense which may be incurred by
it by reason of taking or continuing to take any such action. The Agent shall in
all cases be fully protected in acting, or in refraining from acting, under this
Agreement and the other Operative  Documents in accordance with a request of the
Required  Participants,  and such request and any action taken or failure to act
pursuant thereto shall be binding upon all the Participants.

         SECTION 14.5. Notice of Default.  The Agent shall not be deemed to have
knowledge or notice of the  occurrence of any Default or Event of Default unless
the Agent has  received  notice  from a  Participant,  the  Lessor or the Lessee
describing  such  Default or Event of Default and stating  that such notice is a
"notice of default".  In the event that the Agent  receives  such a notice,  the
Agent  shall give notice  thereof to the other  parties  hereto.  Subject to the
provisions  of Section 11 and  Section  15.5  hereof,  the Agent shall take such
action with respect to such  Default or Event of Default as shall be  reasonably
directed by the Required Participants;  provided that unless and until the Agent
shall have received such  directions,  the Agent may (but shall not be obligated
to) take such action,  or refrain from taking such action,  with respect to such
Default or Event of Default as it shall deem  advisable in the best interests of
the Participants.

         SECTION  14.6.  Non-Reliance  on Agent  and  Other  Participants.  Each
Participant  expressly  acknowledges  that  neither  the  Agent  nor  any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates has made
any representations or warranties to it and that no act by the Agent hereinafter
taken, including any review of the affairs of the Lessor or the Lessee, shall be
deemed  to  constitute  any  representation  or  warranty  by the  Agent  to any
Participant. Each Participant represents to the Agent that it has, independently
and without reliance upon the Agent or any other Participant,  and based on such
documents and information as it has deemed  appropriate,  made its own appraisal
of and  investigation  into the business,  operations,  property,  financial and
other condition and  creditworthiness of the Lessor, the Lessee and the Property
and made its own decision to purchase its Participation  Interest  hereunder and
enter  into this  Agreement.  Each  Participant  also  represents  that it will,
independently  and  without  reliance  upon the  Agent,  the Lessor or any other
Participant,  and  based on such  documents  and  information  as it shall  deem
appropriate at the time,  continue to make its own credit  analysis,  appraisals
and decisions in taking or not taking action under this  Agreement and the other
Operative  Documents,  and to make such  investigation  as it deems necessary to
inform  itself as to the  business,  operations,  property,  financial and other
condition and creditworthiness of the Lessor and the Lessee. Except for notices,
reports  and  other  documents   expressly  required  to  be  furnished  to  the
Participants  by the  Agent  hereunder,  the  Agent  shall  not have any duty or
responsibility  to provide any Participant with any credit or other  information
concerning  the  business,   operations,   property,   condition  (financial  or
otherwise),  prospects or creditworthiness of the Lessor or the Lessee which may
come  into  the  possession  of the  Agent  or any of its  officers,  directors,
employees, agents, attorneys-in-fact or Affiliates.

         SECTION 14.7. Indemnification.  The Participants agree to indemnify the
Agent in its  capacity as such (to the extent not  reimbursed  by the Lessee and
without  limiting the obligation of 

                                      -75-
<PAGE>

the  Lessee  to  do  so),  ratably  according  to  their  respective  Commitment
Percentages in effect on the date on which  indemnification is sought under this
Section  14.7 (or, if  indemnification  is sought  after the date upon which the
Commitments  shall have  terminated and the  Participation  Interests shall have
been paid in full,  ratably  in  accordance  with their  Commitment  Percentages
immediately  prior to such  date),  from and  against  any and all  liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses  or  disbursements  of any  kind  whatsoever  which  may  at  any  time
(including,  without  limitation,  at any  time  following  the  payment  of the
Participation  Interests)  be imposed on,  incurred  by or asserted  against the
Agent in any way relating to or arising out of, the Commitments, this Agreement,
the Property, any of the other Operative Documents or any documents contemplated
by or referred to herein or therein or the transactions  contemplated  hereby or
thereby  or any action  taken or  omitted by any of them under or in  connection
with any of the foregoing;  provided that no Participant shall be liable for the
payment  of any  portion  of such  liabilities,  obligations,  losses,  damages,
penalties, actions, judgments, suits, costs, expenses or disbursements resulting
solely  from the gross  negligence  or  willful  misconduct  of the  Agent.  The
agreements in this Section 14.7 shall  survive the payment of the  Participation
Interests and all other amounts payable hereunder.

         SECTION  14.8.  Agent in its  Individual  Capacity.  The  Agent and its
Affiliates may make loans to, accept  deposits from and generally  engage in any
kind of business  with the Lessor or the Lessee as though the Agent were not the
Agent  hereunder and under the other  Operative  Documents.  With respect to its
Participation Interest purchased by it, the Agent shall have the same rights and
powers under this Agreement and the other Operative Documents as any Participant
and may  exercise  the same as  though  it were  not the  Agent,  and the  terms
"Participant"  and  "Participants"  shall  include  the Agent in its  individual
capacity.

         SECTION 14.9.  Successor  Agent.  The Agent may resign as Agent upon 20
days' notice to the  Participants,  the Lessor or the Lessee. If the Agent shall
resign as Agent under this Agreement and the other Operative Documents, then the
Required  Participants  shall  appoint a successor  agent for the  Participants,
which successor agent shall be a commercial bank organized under the laws of the
United  States of  America  or any State  thereof  or under the laws of  another
country  which is doing  business  in the United  States of America and having a
combined capital, surplus and undivided profits of at least $100,000,000 (and if
no Default or Event of Default  exists,  shall be approved by the Lessee  (which
consent shall not be  unreasonably  withheld)),  whereupon such successor  agent
shall  succeed to the  rights,  powers  and  duties of the  Agent,  and the term
"Agent" shall mean such  successor  agent  effective upon such  appointment  and
approval,  and the former  Agent's  rights,  powers and duties as Agent shall be
terminated,  without any other or further act or deed on the part of such former
Agent  or any of the  parties  to this  Agreement.  If no  successor  Agent  has
accepted appointment as Agent by the date which is 20 days following a resigning
Agent's  notice  of  resignation,   the  resigning  Agent's   resignation  shall
nevertheless  thereupon become effective and the Participants  shall perform all
of the duties of the Agent  hereunder  until such time,  if any, as the Required
Participants  appoint a successor  Agent as provided  above.  After any retiring
Agent's  resignation  as Agent,  all of the  provisions of this Section 14 shall
inure to its benefit as to any actions  taken or omitted to be taken by it while
it was Agent under this Agreement and the other Operative Documents.

Improvements,  payment of the Advances and the  Participation  Interests and any

together constitute but one and the same instrument.

         SECTION  15.5.  Amendments.  Subject  to the  provisions  of Section 11
hereof,  no Operative  Document nor any of the terms thereof may be  terminated,
amended,  supplemented,  waived or  modified  with  respect to the  Lessee,  the
Lessor,  the Agent or any Participant,  except (a) in the case of a termination,

         Sections 7 and 10 of this Participation Agreement;

                           (iii)  reduce,  modify,  amend or  waive  any fees or

         SECTION 15.6. Headings,  etc. The Table of Contents and headings of the

         SECTION 15.7. Parties in Interest. Except as expressly provided herein,
none of the  provisions  of this  Participation  Agreement  are intended for the
benefit of any Person except the parties  hereto.  Subject to the  provisions of
Section  25.1 of the Lease,  the Lessee  shall not assign or transfer any of its
rights or obligations  under the Operative  Documents  without the prior written
consent of the Lessor,  the Agent and the  Participants,  except that the Lessee
may without such consent  assign rights or  obligations  of the Lessee under the
Operative  Documents  to an Affiliate  of the Lessee,  provided  that the Lessee
remains  primarily liable with respect to such obligations and provides its full
unconditional and irrevocable  guaranty of such  Subsidiary's  obligations under
the Operative  Documents,  such guaranty to be in form and substance  reasonably
satisfactory  to the  Required  Participants.  If the Lessor,  the Agent and the
Participants  consent  to any such  assignment  or  transfer  to a Person not an
Affiliate of the Lessee,  the Lessee shall remain  primarily liable with respect
to such  obligations  and  provide its full and  unconditional  guaranty of such
Person's obligations under the Operative Documents,  such guaranty to be in form
and substance reasonably satisfactory to the Required Participants.

         SECTION 15.8. GOVERNING LAW. THIS PARTICIPATION  AGREEMENT SHALL IN ALL
RESPECTS  BE  GOVERNED  BY THE  LAW OF THE  STATE  OF  ILLINOIS  (EXCLUDING  ANY
CONFLICT-OF-LAW  OR  CHOICE-OF-LAW  RULES WHICH MIGHT LEAD TO THE APPLICATION OF
THE INTERNAL LAWS OF ANY OTHER  JURISDICTION) AS TO ALL MATTERS OF CONSTRUCTION,
VALIDITY AND PERFORMANCE.

         SECTION  15.9.  Severability.   Any  provision  of  this  Participation
Agreement that is prohibited or unenforceable  in any jurisdiction  shall, as to
such  jurisdiction,  be  ineffective  to  the  extent  of  such  prohibition  or
unenforceability  without  invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction.

         SECTION 15.10. Liability Limited. (a) The parties hereto agree that the
Lessor shall have no personal  liability  whatsoever to the Lessee, the Agent or
any Participant or their  respective  successors and assigns for any claim based
on or in respect of the Lease or any of the other Operative Documents or arising
in any way from the  transactions  contemplated  hereby  or  thereby;  provided,
however,  that the Lessor shall be liable in its individual capacity (a) for its
own willful  misconduct or gross  negligence  (or  negligence in the handling of
funds),  (b) for liabilities  that may result from its breach of the covenant to
remove  Lessor Liens set forth in Section  10.3,  or (c) for any Tax based on or
measured by any fees,  commission or  compensation  received by it for acting as
the Lessor as  contemplated  by the Operative  Documents.  It is understood  and
agreed that, except as provided in the preceding  proviso:  (i) the Lessor shall
have no  personal  liability  under  any of the  Operative  Documents;  (ii) all
obligations  of the Lessor to the  Lessee,  the Agent and the  Participants  are
solely  nonrecourse  obligations  and shall be  enforceable  solely  against the
interest of the Lessor in the Property; and (iii) all such personal liability of
the  Lessor  is  expressly  waived  and  released  as a  condition  of,  and  as
consideration for, the execution and delivery of the Operative  Documents by the
Lessor.  Notwithstanding anything contained herein, the limitations on liability
stated in the preceding  provisions of this Section  15.10(a) shall not apply to
liability of the Lessor arising  because of a breach of the Lessor's  obligation
to remove  Lessor  Liens or because of its  receiving  Advances  

                                      -79-
<PAGE>

and failing to disburse  Advances to the Lessee in accordance with the Operative
Documents,  or failure to  disburse  proceeds  from the sale of the  Property in
accordance with the Lease and this Participation Agreement.

                  (b) No  Participant  shall  have any  obligation  to any other
Participant  or to  the  Lessee,  the  Lessor  or  the  Agent  with  respect  to
transactions  contemplated by the Operative Documents,  except those obligations
of such Participant  expressly set forth in the Operative Documents or except as
set  forth  in  the  instruments  delivered  in  connection  therewith,  and  no
Participant  shall be liable for  performance  by any other party hereto of such
other party's  obligations under the Operative  Documents except as otherwise so
set forth.

         SECTION 15.11.  Further  Assurances.  The parties hereto shall promptly
cause to be taken, executed,  acknowledged or delivered,  at the sole expense of
the Lessee, all such further acts, conveyances,  documents and assurances as the
other parties may from time to time reasonably request in order to carry out and
effectuate the intent and purposes of this  Participation  Agreement,  the other
Operative  Documents,  and the  transactions  contemplated  hereby  and  thereby
(including, without limitation, the preparation, execution and filing of any and
all  Uniform   Commercial  Code  financing   statements  and  other  filings  or
registrations which the parties hereto may from time to time request to be filed
or  effected).  The Lessee,  at its own  expense  and without  need of any prior
request  from any  other  party,  shall  take such  action  as may be  necessary
(including any action  specified in the preceding  sentence),  or (if the Lessor
shall so request) as so requested, in order to maintain and protect all security
interests provided for hereunder or under any other Operative Document.

         SECTION 15.12. Submission to Jurisdiction. The Lessee hereby submits to
the  nonexclusive  jurisdiction  of the  United  States  District  Court for the
Northern  District of Illinois and of any Illinois  state court  sitting in Cook
County for purposes of all legal  proceedings  arising out of or relating to the
Operative  Documents  or  the  transactions   contemplated  hereby.  The  Lessee
irrevocably  waives, to the fullest extent permitted by law, any objection which
it may now or hereafter  have to the laying of the venue of any such  proceeding
brought in such a court and any claim that any such proceeding brought in such a
court has been brought in an inconvenient forum.

         SECTION  15.13.  Confidentiality.   The  Lessor,  the  Agent  and  each
Participant  represent  that  they  will  maintain  the  confidentiality  of the
transactions  contemplated by, and of any written or oral  information  provided
under,  the  Operative  Documents  by or on  behalf of the  Lessee  (hereinafter
collectively called "Confidential  Information"),  subject to the Lessor's,  the
Agent's and each  Participant's (a) obligation to disclose any such Confidential
Information pursuant to a request or order under applicable laws and regulations
or pursuant to a subpoena or other legal process, (b) right to disclose any such
Confidential Information to its bank examiners,  Affiliates,  auditors,  counsel
and other professional advisors and to other Participants, (c) right to disclose
any such  Confidential  Information in connection with any litigation or dispute
involving  the  Participants  and  the  Lessee  or any of its  Subsidiaries  and
Affiliates  and (d)  right to  provide  such  information  to  Sub-Participants,
prospective  Sub-Participants  to which  sales of  participating  interests  are
permitted pursuant to this Participation  Agreement and prospective assignees to
which  assignments  of interests  are permitted  pursuant to this  Participation
Agreement, but only if (i) such Sub-Participant,  prospective Sub-Participant or
prospective  assignee agrees in writing to maintain the  confidentiality

                                      -80-
<PAGE>

of such information on terms  substantially  similar to those of this Section as
if it were a  "Participant"  party hereto and (ii) the Lessee receives copies of
such written agreement prior to the release of such information. Notwithstanding
the foregoing, any such information supplied to a Participant,  Sub-Participant,
prospective  Sub-Participant  or prospective  assignee under this  Participation
Agreement shall cease to be  Confidential  Information if it is or becomes known
to such Person by other than unauthorized disclosure,  or if it becomes a matter
of public knowledge.

         SECTION 15.14. WAIVER OF JURY TRIAL. EACH OF THE LESSEE, THE AGENT, THE
LESSOR,  AND EACH  PARTICIPANT  HEREBY  IRREVOCABLY  WAIVES ANY AND ALL RIGHT TO
TRIAL  BY  JURY  IN ANY  LEGAL  PROCEEDING  ARISING  OUT OF OR  RELATING  TO THE
OPERATIVE DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         SECTION  15.15.  Usury  Savings  Clause.   Nothing  contained  in  this
Participation  Agreement  or the other  Operative  Documents  shall be deemed to
require  the  payment of  interest  or other  charges by the Lessee or any other
Person in excess of the amount  which may be may  lawfully be charged  under any
applicable  usury laws.  In the event that the Lessor or any other  Person shall
collect moneys under the Participation Agreement or any other Operative Document
which are deemed to constitute  interest  (including,  without  limitation,  the
Basic Rent or  Supplemental  Rent) which would increase the effect interest rate
to a rate in excess of that permitted to be charged by applicable  law, all such
sums deemed to constitute  interest in excess of the legal rate shall, upon such
determination,  at the option of the Person to whom such  payment  was made,  be
returned to the Person  making such payment or credited  against  other  amounts
owed by the person making such payment.

                            [signature pages follow]

                                   EXPLANATION

1.       The  Applicable  Margin  for  each  Eurodollar  Rate  Advance  and  the
         Commitment  Fee Rate will be set for each Pricing  Period and will vary
         depending  upon  whether  such  period is a Level 1  Period,  a Level 2
         Period, a Level 3 Period, a Level 4 Period or a Level 5 Period.

2.       The first Pricing Period, which commences on the date of this Agreement
         and ends on September 30, 1997, will be a Level 3 Period.

3.       The Second Pricing Period,  which commences on October 1, 1997 and ends
         on November 30,  1997,  will be a Level 1 Period,  a Level 2 Period,  a
         Level 3  Period,  a Level 4 Period or a Level 5 Period  depending  upon
         Lessee's  Total  Funded Debt Ratio (and,  with  respect to  determining
         pricing  at  Level  1  Pricing  only,   EBITDA)  for  the   consecutive
         four-fiscal quarter period ending on June 30, 1997 as follows:

         (a)      If, during the Second Pricing Period (i) Lessee's Total Funded
                  Debt  Ratio is 1.00 or less and (ii)  Lessee's  EBITDA for the
                  previous  four  quarters  is  $400,000,000  or more,  Lessee's
                  pricing will be a Level 1 Period.

         (b)      If,  during the Second  Pricing  Period,  (i)  Lessee's  Total
                  Funded  Debt Ratio is more than 1.00 but less than or equal to
                  1.50, or (ii) Lessee's Total Funded Debt Ratio is less than or
                  equal  to 1.00  but  Lessee's  EBITDA  for the  previous  four
                  quarters is less than $400,000,000, Lessee's pricing will be a
                  Level 2 Period.

         (c)      If, during the Second  Pricing  Period,  Lessee's Total Funded
                  Debt  Ratio is more  than 1.50 but less than or equal to 2.00,
                  Lessee's pricing will be a Level 3 Period.

         (d)      If, during the Second  Pricing  Period,  Lessee's Total Funded
                  Debt  Ratio is more  than 2.00 but less than or equal to 2.50,
                  Lessee's pricing will be Level 4 Period.

         (e)      If, during the Second  Pricing  Period,  Lessee's Total Funded
                  Debt Ratio is more than 2.50, Lessee's pricing will be Level 5
                  Period.

4.       Each  Pricing  Period  thereafter  will be a Level 1 Period,  a Level 2
         Period,  a  Level  3  Period,  a Level  4  Period  or a Level 5  Period
         depending upon Lessee's  Total Funded Debt Ratio (and,  with respect to
         determining  pricing  at Level 1  Pricing  only,  EBITDA)  for the most
         recent consecutive four-fiscal quarter period ending prior to the first
         day of such Pricing Period as follows:

         (a)      If, during any Pricing  Period (i) Lessee's  Total Funded Debt
                  Ratio  is  1.00 or  less  and  (ii)  Lessee's  EBITDA  for the
                  previous  four  quarters  is  $400,000,000  or more,  Lessee's
                  pricing will be a Level 1 Period.

         (b)      If, during any Pricing Period,  (i) Lessee's Total Funded Debt
                  Ratio is more  than  1.00 but less  than or equal to 1.50,  or
                  (ii) Lessee's Total Funded Debt Ratio is less than or equal to
                  1.00 but  Lessee's  EBITDA for the previous  four  quarters is
                  less than  $400,000,000,  Lessee's  pricing  will be a Level 2
                  Period.

         (c)      If,  during any Pricing  Period,  Lessee's  Total  Funded Debt
                  Ratio  is more  than  1.50  but  less  than or  equal to 2.00,
                  Lessee's pricing will be a Level 3 Period.

         (d)      If,  during any Pricing  Period,  Lessee's  Total  Funded Debt
                  Ratio  is more  than  2.00  but  less  than or  equal to 2.50,
                  Lessee's pricing will be Level 4 Period.

         (e)      If,  during any Pricing  Period,  Lessee's  Total  Funded Debt
                  Ratio is more  than  2.50,  Lessee's  pricing  will be Level 5
                  Period.

5.       Level 1 Period will also apply  during any Pricing  Period  (other than
         the first  Pricing  Period)  in which  Lessee's  senior  long term debt
         rating  from S&P or Moody's is equal to or better  than  either BBB- or
         Baa3 or Lessee's  subordinated debt rating from S&P or Moody's is equal
         to or better than BB+ or Bal.

                           (a) Credit Agreement  Representations and Warranties.
         All  representations and warranties of the Company contained in Article
         V of the Credit Agreement are true and correct in all material respects
         on and as of the date  hereof  and as of the  Effective  Date as though
         made on and as of said dates.

                           (b)  Litigation.  As of the date hereof and as of the
         Effective Date, except as specifically  disclosed in the Company's Form

         Governmental  Authority,  against the Company or any of its  properties

                           (c) Material  Adverse  Effect.  Since March 31, 1997,
         the date of the most recent audited  financial  statements  provided by
         the  Company  to the Agent and the  Banks,  there has been no  Material
         Adverse Effect.

                           (d) Financial  Statements.  The Company has delivered
         to the Agent and each of the Banks copies of the unaudited consolidated
         balance  sheet  of the  Company  as at the  end  of,  and  its  related
         unaudited  consolidated  statements of income, changes in shareholder's
         equity and cash flow of the Company  for,  the  quarterly  period ended
         June 29, 1997,  certified by the Chief Financial  Officer or Controller
         of the Company. Such financial statements have been accurately prepared
         from the books  and  records  of the  Company.  There  are no  material
         liabilities,  contingent or otherwise,  of the Company as of such date,
         not  reflected  in such  balance  sheet of the Company as of such date.
         Since  such  date,  there  have not been any  changes  (whether  or not
         covered by insurance) in assets,  liabilities or financial  position of
         the Company from those set forth in such  balance  sheet of the Company
         as of such date,  other than changes in the ordinary course of business
         which  have  not,  either  individually  or  in  the  aggregate,   been
         materially  adverse.  The Company does not know of any fact (other than
         matters of a general economic nature) that materially affects adversely
         the business,  operations or properties of the Company,  or the ability
         of the  Company to perform its  obligations  under this  Extension  and
         Modification or the Credit Agreement (as extended and modified hereby).

                           (e) No Event of Default. No event has occurred and is
         continuing,  or would  result  from the  extension  or  issuance of any
         Letter of Credit or any other transaction  contemplated hereby or under
         the  Credit  Agreement  (as  extended  and  modified   hereby),   which
         constitutes a Default or an Event of Default.

                           (f) Due Organization. The Company is a duly organized
         corporation created under the laws of Delaware, has the requisite power
         to carry on its present and  proposed  activities,  and has full power,
         right and authority (i) to enter into,  execute and deliver this Second
         Extension  and  Modification  and (ii) to perform and observe the terms
         and provisions of this Second Extension and Modification and the Credit
         Agreement (as extended and modified hereby).

                           (g) Compliance with Documents. The Company is in full
         compliance  with all of the material terms and conditions of the Credit
         Agreement as amended to the date hereof.

                           (h) Due  Authorization.  The  Company  has  taken  or
         caused to be taken all requisite  corporate action to authorize (i) the
         extension,  issuance, execution and delivery of, and the performance of
         its obligations  under,  this Second  Extension and  Modification,  the
         Credit  Agreement  (as extended and modified  hereby),  and any and all
         instruments,  certificates  and  documents  required  to be executed or
         delivered pursuant to or in connection herewith or therewith,  and (ii)
         the consummation by the Company of the transactions  contemplated under
         each of the foregoing documents.

                           (i) Corporate Power; No Violation.  The execution and
         delivery of, and performance by the Company of its  obligations  under,
         this  Second  Extension  and  Modification,  the Credit  Agreement  (as
         extended and modified hereby), and any and all instruments or documents
         required to be executed in connection  herewith or therewith,  were and

         of   any   applicable   law,   regulation,   decree   or   governmental
         authorization,  or its bylaws,  and will not violate or cause a default
         under any provision of any contract, agreement,  mortgage, indenture or
         other undertaking to which it is a party or which is binding upon it or
         any of its property or assets, and will not result in the imposition or
         creation of any lien,  charge or encumbrance upon any of its properties
         or assets  pursuant to the provisions of any such contract,  agreement,
         mortgage, indenture or undertaking.

                           (j)   Licenses,    Approvals.   All   authorizations,
         licenses, consents, approvals and undertakings which are required to be
         obtained by the Company under any applicable law in connection with the
         execution,  delivery and  performance  of, and the legality,  validity,
         binding effect and  enforceability of the Company's  obligations under,
         or in connection  with, this Second  Extension and Modification and the
         Credit  Agreement  (as  extended  and  modified  hereby) have been duly
         obtained  or made  and all  such  authorizations,  licenses,  consents,
         approvals and undertakings are in full force and effect.

                           (k) Binding  Obligations.  This Second  Extension and
         Modification and the Credit Agreement (as extended and modified hereby)
         constitute  the valid and legally  binding  obligations of the Company,
         which  obligations are enforceable in accordance with their  respective
         terms.

instrument or document executed in connection herewith,  nor any action taken by
the Agent,  the Issuer or any Bank in connection with this Second  Extension and

defined  in  the  Credit  Agreement  (as  extended  and  modified  hereby,   and

provision of this Second Extension and Modification, the Credit Agreement or any
other  document or any other  instrument  or  agreement  required  hereunder  or
thereunder shall not in any way affect or impair the legality or  enforceability
of the remaining  provisions  of this Second  Extension  and  Modification,  the
