                              ABOUT THE PROSPECTUS

This prospectus is part of a "shelf"  registration  statement that we filed with
the SEC.  By using a  shelf-registration  statement,  we may sell,  from time to
time, in one or more offerings,  any combination of the securities  described in
this prospectus. The total dollar amount of the securities we sell through these
offerings will not exceed $100,000,000. This prospectus only provides you with a
general  description  of  the  securities  we  may  offer.  Each  time  we  sell
securities,  we will  provide a prospectus  supplement  that  contains  specific
information  about the terms of the  securities  being  offered.  The prospectus
supplement  may  also  add,  update  or  change  information  contained  in this
prospectus.  You should read both this prospectus and any prospectus  supplement
together with the additional  information described under the heading "WHERE YOU
CAN FIND MORE INFORMATION."

                       WHERE YOU CAN FIND MORE INFORMATION

automatically update and supersede this information.

<PAGE>
                                   THE COMPANY

We are a real  estate  investment  trust based in  Houston,  Texas.  We acquire,
develop and operate neighborhood and community shopping centers in the "sunbelt"
region of the United States. We have engaged in these activities since 1989.

As of December 31, 1998, we owned  controlling  interest in 24 shopping  centers
and one property under  development.  The operating shopping centers consists of
approximately  3 million square feet of gross leasable  area.  These  properties
range in size from approximately 26,000 to approximately 316,000. Our properties
are located in Texas (17  properties)  and the  following  states:  Arizona (3),
Florida (2) and Tennessee  (2). Our shopping  centers are anchored  primarily by
national and regional  supermarkets,  drugstores  and other  retailers that sell
basic  necessity-type  items. For fiscal year ended December 31, 1998, no single
tenant  represented  more than 3% of our  revenues.  On December 31,  1998,  our
properties were approximately 95% leased.

Our executive offices are located at 5847 San Felipe, Suite 850, Houston,  Texas
77057, and our telephone number (713) 781-2860.


           CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

We  have  made  statements  in  this  prospectus  and any  supplement  that  are
"forward-looking"  in that they do not discuss historical fact, but instead note
future  expectations,  projections,  intentions  or other items  relating to the
future.  These  forward-looking  statements  include those made in the documents
incorporated by reference in this prospectus.

Forward-looking statements are subject to known and unknown risks, uncertainties
and other  facts that may cause our  actual  results  or  performance  to differ
materially from those contemplated by the  forward-looking  statements.  Many of
those factors are noted in conjunction  with the  forward-looking  statements in
the text.  Other  important  factors that could cause  actual  results to differ
include:

- -     Our inability to identify  properties to acquire,  effect  acquisitions or
      successfully  integrate acquired properties and operations could result in
      decreased market penetration, adverse effects on results of operations and
      other adverse results.  This same result could occur if the results of our
      efforts  to  implement  our  property  development  strategy  fail  or  we
      experience public opposition to our development plans, construction delays
      or cost overruns or if we are unable to obtain necessary permits.

- -     The effect of economic  conditions.  If an economic  downturn occurs,  the
      demand and rents for  neighborhood  and community  shopping  centers could
      fall  and  adversely  affect  our  financial   condition  and  results  of
      operations.  Our financial  condition and results of operations could also
      be  adversely  affected  if our  tenants  are unable to make  their  lease
      payments or fail to renew their leases.

- -    Failure to qualify as a REIT.  We elected to be taxed as a REIT for federal
     income tax  purposes for our taxable  year ended  December  31,  1998,  and
     expect to continue to elect such  status.  Although we believe that we were
     organized and have been operating in conformity with the  requirements  for
     qualification  as a REIT  under  the  Internal  Revenue  Code of  1986,  as
     amended,  we cannot  assure you that we will continue to qualify as a REIT.
     Qualification  as a REIT involves the  application of highly  technical and
     complex  Internal  Revenue Code provisions for which there are only limited
     judicial or administrative interpretations.  If in any taxable year we fail
     to qualify as a REIT, we would not be allowed a deduction for distributions
     to  shareholders  for  computing  taxable  income  and would be  subject to
     federal  taxation at regular  corporate  rates.  Unless  entitled to relief
     under certain  statutory  provisions,  we would also be  disqualified  from
     treatment as a REIT for the four taxable  years  following  the year during
     which   qualification   was  lost.  As  a  result,   our  ability  to  make
     distributions to our shareholders would be adversely affected. See "Federal
     Income Tax Consequences - REIT Qualification."

- -     The costs of our capital. That cost depends on many factors, some of which
      are beyond our control,  such as interest  rates,  ratings,  prospects and
      outlook.

- -     Actions of our competitors and our ability to respond to those actions. We
      seek to remain  competitive  in the  neighborhood  and community  shopping
      center real estate markets that we currently serve.

- -     Changes in  government  regulations,  tax rates and similar  matters.  For
      example, changes in real estate and zoning laws could adversely affect our
      financial condition and results of operations.

- -     Environmental uncertainties and natural disasters. Any unexpected material
      environmental  event or natural disaster that affects our properties could
      adversely affect our financial condition and results of operations.

- -     Unexpected  Year 2000  Problems.  We have  completed our evaluation of the
      risks of a material  effect on our  results of  operations  and  financial
      condition with respect to our management  information systems and the year
      2000 and do not believe that we will be materially  affected by any future
      costs to make our management information systems Year 2000 compliant.  Our
      application  software,  including our accounting  and property  management
      software, have been certified by our vendors as Year 2000 compliant.

- -    Other risks detailed in our other SEC reports or filings.

We do not  promise  to update  forward-looking  information  to  reflect  actual
results or changes in  assumptions  or other  factors  that could  affect  those
statements.

<PAGE>

                                 USE OF PROCEEDS

We intend to use the net proceeds  from the sale of the  securities  for general
corporate  purposes,  including  working  capital,  acquisitions,  repayment  or
refinancing of debt, capital expenditures and other business  opportunities.  We
will describe in each  prospectus  supplement any proposed use of proceeds other
than for general corporate purposes.


                          DESCRIPTION OF CAPITAL SHARES

Our First Amended and Restated  Declaration  of Trust provides that we may issue
up to  550,000,000  shares of beneficial  interest,  consisting  of  500,000,000
common shares and 50,000,000 preferred shares, 20,000 of which are authorized to
be issued at $100 par value per share and the remainder of which are  authorized
to be issued  at no par value per  share.  At March 1,  1999,  9,514,889  common
shares  were  issued and  outstanding  and no  preferred  shares were issued and
outstanding.

Common Shares

Holders of our common  shares are  entitled  to one vote per share.  There is no
cumulative  voting in the  election  of trust  managers.  The board may  declare
dividends on common shares in its discretion if funds are legally  available for
those purposes. On liquidation,  common shareholders are entitled to receive pro
rata  any of  our  remaining  assets,  after  we  satisfy  or  provide  for  the
satisfaction of all liabilities and obligations on our preferred shares, if any.
Common  shareholders do not have conversion,  redemption or preemptive rights to
subscribe  for or  purchase  any  of  our  capital  shares  or any of our  other
securities.

Preferred Shares

Under our charter,  the board is authorized,  without shareholder  approval,  to
issue preferred  shares in one or more series,  with the  designations,  powers,
preferences,  rights, qualifications,  limitations and restrictions as the board
determines.  Thus, the board, without shareholder approval,  could authorize the
issuance of preferred shares with voting, conversion and other rights that could
adversely affect the voting power and other rights of our common shareholders or
that could make it more  difficult for another  company to enter into a business
combination with us.

Restrictions on Ownership

In order for us to qualify as a REIT under the Internal  Revenue Code,  not more
than 50% in value of our  outstanding  capital shares may be owned,  directly or
indirectly,  by five or fewer  individuals or entities during the last half of a
taxable year. In addition,  our capital shares must be beneficially owned by 100
or more  persons  during at least 335 days of a taxable  year of 12  months,  or
during a proportionate part of a shorter taxable year.

Because the board  believes it is  essential  for us to continue to qualify as a
REIT, our charter provides,  subject to certain  exceptions,  that no holder may
own, or be deemed to own by virtue of the  attribution  provisions  of the Code,
more than 9.8% of our total outstanding  capital shares.  Any transfer of shares
will not be valid if it would:

- -    create a direct or  indirect  ownership  of shares in excess of 9.8% of our
     total outstanding capital shares;

- -    result in shares being owned by fewer than 100 persons;

- -    result in our being  "closely held" within the meaning of Section 856(h) of
     the Code; or

- -    result in our disqualification as a REIT.

Ownership  of  over  9.8%  of  our  total   outstanding   capital   shares  will
automatically  be deemed to be  transferred  to us as trustee of a trust for the
exclusive  benefit of the  transferees  to whom such  shares may  ultimately  be
transferred  without violating the 9.8% ownership limit.  While in trust,  these
share will not be entitled to vote (except as required by law),  and will not be
entitled to participate in dividends or other distributions.  These shares would
be treated  as if  offered to us for sale at a price  equal to the lesser of the
price  paid for the  shares  and the  market  price of the shares on the date we
accept the offer to  purchase  the  shares.  We have the right to  purchase  the
shares for 90 days after the  transfer of the shares  resulted in a  shareholder
owning in excess of 9.8% of our total  outstanding  shares or our trust managers
determine that a transfer resulting in a shareholder owning in excess of 9.8% of
our  outstanding  shares has occurred.  All  certificates  representing  capital
shares will bear a legend referring to the restrictions described above.

These restrictions on ownership may have the effect of precluding acquisition of
control unless the board and  shareholders  determine  that  maintenance of REIT
status is no longer in our best interests.

                         DESCRIPTION OF DEBT SECURITIES


The senior debt securities will be issued under a senior indenture to be entered
into between us and an appointed  trustee and the  subordinated  debt securities
will be issued under a subordinated indenture also to be entered into between us
and an appointed  trustee.  The term "trustee" as used in this prospectus refers
to any bank that we may  appoint  as trustee  under the terms of the  applicable
indenture,  in  its  capacity  as  trustee  for  the  senior  securities  or the
subordinated securities.

We have summarized  certain terms and provisions of the indentures.  The summary
is not complete.  If we refer to particular  provisions of the  indentures,  the
provisions,   including  definitions  of  certain  terms,  are  incorporated  by
reference as a part of the summary.  We have included  references to articles or
section numbers of the applicable indentures so that you can easily locate these
provisions  in the  indentures.  The  indentures  are filed as  exhibits  to the
registration  statement of which this prospectus is a part, and are incorporated
by reference.  You should refer to the indentures  for  provisions  which may be
important to you. The indentures are subject to the Trust Indenture Act of 1939,
as  amended.  To obtain a copy of the  indentures,  see "WHERE YOU CAN FIND MORE
INFORMATION" on page 2.

General

The debt securities will be direct,  unsecured general  obligations.  The senior
debt  securities  will  rank  equally  with  all  of  our  other  unsecured  and
unsubordinated   indebtedness.   The   subordinated   debt  securities  will  be
subordinated in right of payment to the prior payment in full of our senior debt
securities. See "Subordinated Debt Securities" on page 7.

The  indentures  do not limit the amount of debt  securities  that we can offer.
Each  indenture  allows us to issue debt  securities up to the principal  amount
that may be authorized by us. We may issue  additional debt  securities  without
your  consent.  We may issue debt  securities  in one or more  series.  All debt
securities  of one  series  need not be  issued  at the same  time  and,  unless
otherwise provided, a series may be reopened, without the consent of the holders
of the  debt  securities  of such  series,  for  issuances  of  additional  debt
securities of such series. (Section 301)

A prospectus  supplement and any supplemental  indentures relating to any series
of debt  securities  being offered will include  specific  terms relating to the
offering. These terms will include some or all of the following:

- -    the title, type and amount of the debt securities;

- -    the total principal amount and priority of the debt securities;

- -    the percentage of the principal amount at which the debt securities will be
     issued and any  payments  due if the  maturity  of the debt  securities  is
     accelerated;

- -    the dates on which the principal of the debt securities will be payable;

- -    the  interest  rates  (which  may be  fixed  or  variable)  which  the debt
     securities will bear, or the method for determining rates;

- -    the dates from which the interest on the debt securities will accrue and be
     payable, or the method of determining those dates, and any record dates for
     the payments due;

- -    any  provisions  for  redemption,   conversion  or  exchange  of  the  debt
     securities,  at our option or otherwise,  including the periods, prices and
     terms of redemption or conversion;

- -    any  sinking  fund  or  similar  provisions,  which  would  obligate  us to
     repurchase or otherwise redeem the debt securities, along with the periods,
     prices and terms of redemption, purchase or repayment;

- -    the amount or percentage  payable if we accelerate the maturity of the debt
     securities, if other than the principal amount;

- -    any changes to or  additional  events of default or covenants  set forth in
     the indentures;

- -    the terms of subordination, if any;

- -    any special tax implications of the debt securities,  including  provisions
     for original issue discount securities; and

- -    any other terms consistent with the indenture.

The debt securities may be issued in registered,  bearer, coupon or global form.
We may  authorize  and  determine  the terms of a series of debt  securities  by
resolution of our board of trust managers or the pricing  committee of our board
of  trust  managers  or  through  a  supplemental  indenture.  Unless  otherwise
described in the applicable prospectus supplement, we will issue debt securities
only in denominations of $1,000 and integral multiples of that amount.  (Section
301)

Senior Debt Securities

Any  additional  senior debt  securities  we issue will rank equally in right of
payment  with the senior  debt  securities  offered by this  prospectus  and the
applicable  prospectus  supplement.  Further,  the  senior  indenture  does  not
prohibit us from issuing  additional  debt  securities  that may rank equally in
right of payment to the senior debt securities.

Any senior debt  securities  offered  pursuant to the senior  indenture  will be
senior in right of payment to all subordinated  debt securities issued under the
subordinated indenture.

Subordinated Debt Securities

The  subordinated  debt  securities  will have a junior  position  to all of our
senior  debt.  Under  the  subordinated  indenture,  payment  of the  principal,
interest and any premium on the  subordinated  debt securities will generally be
subordinated  and junior in right of payment to the prior payment in full of all
senior debt. The subordinated  indenture  provides that no payment of principal,
interest and any premium on the subordinated  debt securities may be made in the
event:

o    of any  insolvency,  bankruptcy or similar  proceeding  involving us or our
     property; or

o    we fail to pay the principal, interest, any premium or any other amounts on
     any senior debt when due.

The subordinated  indenture will not limit the amount of senior debt that we may
incur. All series of subordinated debt securities as well as other  subordinated
debt issued under the  subordinated  indenture will rank equally with each other
in right of payment.

The subordinated indenture prohibits us from making a payment of principal of or
premium,  if any,  or  interest  on,  or  sinking  fund  requirements  for,  the
subordinated debt securities during the continuance of any default in respect of
certain  senior debt or any default  under any  agreement  pursuant to which the
senior debt was issued beyond the period of grace, unless and until such default
on the senior debt is cured or waived. (Subordinated Indenture Article Sixteen).

Upon any distribution of our assets in connection with any dissolution,  winding
up, liquidation, reorganization, bankruptcy or other similar proceeding relative
to us, our creditors or our property,  the holders of all senior debt securities
will first be entitled to receive  payment in full of the principal  thereof and
premium, if any, and interest due thereon before the holders of the subordinated
debt  securities  are  entitled to receive any payment of the  principal  of and
premium,  if any, or interest on the subordinated debt securities  (Subordinated
Indenture  Article  Sixteen).  Because  of  this  subordination,  if  we  become
insolvent,  our  creditors  who  are  not  holders  of  senior  debt  or of  the
subordinated debt securities may recover less,  ratably,  than holders of senior
debt but may  recover  more,  ratably,  than  holders of the  subordinated  debt
securities.

Global Certificates

Unless  the  prospectus  supplement  otherwise  provides,  we  will  issue  debt
securities as one or more global  certificates  that will be deposited  with The
Depository  Trust  Company.   Unless  otherwise   specified  in  the  applicable
prospectus  supplement,   debt  securities  issued  in  the  form  of  a  global
certificate to be deposited with DTC will be represented by a global certificate
registered in the name of DTC or its nominee.  This means that we will not issue
certificates to each holder.  Generally,  we will issue global securities in the
total principal  amount of the debt  securities in a series.  Debt securities in
the form of a global  certificate may not be transferred except as a whole among
DTC, its nominee or a successor to DTC and any nominee of that successor.

We may determine not to use global  certificates for any series.  In that event,
we will issue debt securities in certificated form.

The laws of some  jurisdictions  require that certain  purchasers  of securities
take physical  delivery of securities in certificated  form. Those laws and some
conditions on transfer of global  securities  may impair the ability to transfer
interests in global securities.

Ownership of Global Securities

So long as DTC or its nominee is the registered owner of a global security, that
entity  will be the sole  holder  of the  debt  securities  represented  by that
instrument.  Both we and the  trustee  are only  required  to  treat  DTC or its
nominee  as the  legal  owner of those  securities  for all  purposes  under the
indenture.

Unless otherwise specified in this prospectus or the prospectus  supplement,  no
actual  purchaser of debt  securities  represented by a global  security will be
entitled to receive  physical  delivery of  certificated  securities  or will be
considered  the holder of those  securities for any purpose under the indenture.
In addition,  no actual  purchaser  will be able to transfer or exchange  global
securities  unless  otherwise  specified in this  prospectus  or the  prospectus
supplement.  As a result,  each actual  purchaser must rely on the procedures of
DTC to exercise any rights of a holder under the  indenture.  Also, if an actual
purchaser  is not a DTC  participant,  the  actual  purchaser  must  rely on the
procedures  of the  participant  through  which it owns its interest in a global
security.

The Depository Trust Company

The following is based on information furnished by DTC and applies to the extent
that  it  is  the  depositary,  unless  otherwise  provided  in  the  prospectus
supplement.

Registered  Owner.  The debt  securities  will be  issued  as  fully  registered
securities in the name of Cede & Co. (which is DTC's partnership  nominee).  The
trustee will deposit the global security with the  depositary.  The deposit with
the  depositary and its  registration  in the name of Cede & Co. will not change
the nature of the actual purchaser's ownership interest in the debt securities.

DTC's  Organization.  DTC is a limited purpose trust company organized under the
New York Banking Law, a "banking organization" within the meaning of that law, a
member of the  Federal  Reserve  System,  a  "clearing  corporation"  within the
meaning  of the  New  York  Uniform  Commercial  Code  and a  "clearing  agency"
registered under the provisions of Section 17A of the Securities Exchange Act of
1934, as amended.

DTC is  owned  by a  number  of its  direct  participants,  the New  York  Stock
Exchange,  Inc., the American Stock Exchange,  Inc. and the National Association
of Securities Dealers,  Inc. Direct participants  include securities brokers and
dealers,  banks,  trust  companies,  clearing  corporations  and  certain  other
organizations  who directly  participate in DTC. Other entities may access DTC's
system by clearing transactions through or maintaining a custodial  relationship
with direct  participants.  The rules applicable to DTC and its participants are
on file with the SEC.

DTC's  Activities.  DTC holds securities that its participants  deposit with it.
DTC  also   facilitates   the  settlement   among   participants  of  securities
transactions,  such as transfers and pledges,  in deposited  securities  through
electronic computerized  book-entry changes in participants' accounts.  Doing so
eliminates the need for physical movement of securities certificates.

Participants'  Records.  Except as otherwise  provided in this  prospectus  or a
prospectus supplement, purchases of debt securities must be made by or through a
direct  participant,  which will  receive a credit for the  securities  on DTC's
records. The purchaser's interest is in turn to be recorded on the participants'
records.  Actual purchasers will not receive written  confirmations  from DTC of
their purchase,  but they generally  receive  confirmations  along with periodic
statements of their  holdings from the  participants  through which they entered
into the transaction.

Transfers of interest in the global  securities will be made on the books of the
participants on behalf of the actual purchasers.  Certificates  representing the
interest of the actual  purchasers in the  securities  will not be issued unless
the use of global  securities is  suspended.  DTC has no knowledge of the actual
purchasers of global securities.  DTC's records only reflect the identity of the
direct participants who are responsible for keeping account of their holdings on
behalf of their customers.

Notices Among the Depositary,  Participants and Actual Owners. Notices and other
communications  by DTC,  its  participants  and the  actual  purchasers  will be
governed  by  arrangements  among  them,  subject to any legal  requirements  in
effect.

Voting Procedures. Neither DTC nor Cede & Co. will give consents for or vote the
global  securities.  DTC  generally  mails an omnibus proxy to us just after the
applicable  record date.  That proxy  assigns Cede & Co.'s voting  rights to the
direct participants to whose accounts the securities are credited at that time.

Payments.  Principal and interest  payments made by us will be delivered to DTC.
DTC's  practice is to credit  direct  participants'  accounts on the  applicable
payment date unless it has reason to believe that it will not receive payment on
that date.  Payments by  participants  to actual  purchasers will be governed by
standing  instructions and customary  practices,  as is the case with securities
held for customers in bearer form or registered in "street name." Those payments
will be the  responsibility  of that  participant,  not DTC,  the trustee or us,
subject to any legal requirements in effect at that time.

We are  responsible for payment of principal,  interest and premium,  if any, to
the  trustee,  who is  responsible  to pay it to  DTC.  DTC is  responsible  for
disbursing  those  payments  to  direct   participants.   The  participants  are
responsible for disbursing payment to the actual purchasers.

Transfer or Exchange of Debt Securities

You may  transfer or exchange  debt  securities  (other than global  securities)
without a service charge at the corporate  trust office of the trustee.  You may
also surrender debt securities (other than global  securities) for conversion or
registration of transfer  without a service charge at the corporate trust office
of the trustee.  You must execute a proper form of transfer and pay any taxes or
other governmental charges resulting from that action.

Transfer Agent

If we  designate a transfer  agent (in  addition to the trustee) in a prospectus
supplement,  we may at any time rescind this  designation or approve a change in
the location  through which any such transfer agent acts. We will,  however,  be
required to  maintain a transfer  agent in each place of payment for a series of
debt securities.  We may at any time designate  additional transfer agents for a
series of debt securities.

Covenants

Under the indentures, we will:

- -    pay the  principal,  interest and any premium on the debt  securities  when
     due;

- -    maintain a place of payment;

- -    deliver a report to the trustee at the end of each  fiscal  year  reviewing
     our obligations under the indentures; and

- -    deposit  sufficient  funds with any paying  agent on or before the due date
     for any principal, interest or any premium.

Events of Default, Notice and Waiver

Events of default under the indentures for any series of debt securities are:

- -    failure for 30 days to pay interest on any debt securities of that series;

- -    failure to pay principal or premium, if any, of any debt securities of that
     series;

- -    failure to pay any sinking fund payment when due;

- -    failure to perform any other covenants  contained in the indentures  (other
     than a  covenant  added  to the  indentures  solely  for the  benefit  of a
     particular  series of debt  securities),  which continues for 60 days after
     written notice as provided in the indenture;

- -    default under any other of our debt instruments with an aggregate principal
     amount outstanding of at least $10,000,000; or

- -    certain  events  of  bankruptcy,  insolvency  or  reorganization,  or court
     appointment of a receiver, liquidator or trustee.

An  event  of  default  for a  particular  series  of debt  securities  does not
necessarily  constitute  an  event  of  default  for any  other  series  of debt
securities  issued under an  indenture.  The trustee may withhold  notice to the
holders of debt securities of any default (except in the payment of principal or
interest) if it considers such withholding of notice to be in the best interests
of the holders.

If an event of default for any series of debt  securities  occurs and continues,
the trustee or the holders of at least 25% of the total principal  amount of the
debt  securities  of the series may declare the entire  principal of that series
due and payable immediately.  (Section 502) The trustee will not be charged with
knowledge  of any event of  default  other than our  failure to make  principal,
interest  or sinking  fund  payments  unless  written  notice is received by the
trustee or the trustee has actual notice of the event of default.  (Section 602)
If this happens, subject to certain conditions, the holders of a majority of the
aggregate  principal  amount of the debt  securities of that series can void the
declaration. (Section 502)

The indentures limit the right to institute legal proceedings.  No holder of any
debt securities will have the right to bring a claim under an indenture  unless:
(i) the holder has given  written  notice of  default to the  trustee;  (ii) the
holders  of not  less  than  25% of  the  aggregate  principal  amount  of  debt
securities  of such series  shall have made a written  request to the trustee to
bring the claim and furnished the trustee such reasonable  indemnification as it
may require;  (iii) the trustee has not commenced  such action within 60 days of
receipt of such notice and indemnification;  and (iv) no direction  inconsistent
with such  request has been given to the trustee by the holders of not less than
a majority  of the  aggregate  principal  amount of the debt  securities  of the
subordination provisions,  the holders of debt securities may enforce payment of
the principal of or premium,  if any, or interest on their debt  securities.  No
holder of debt securities of a particular  series has the right to prejudice the
rights or obtain  priority or preference  over the rights of any other holder of
debt securities of such series. (Section 509)

The holders of a majority in  aggregate  principal  amount of any series of debt
securities  may direct the time,  method and place of conducting  any proceeding
for any remedy available to the trustee or exercising any power conferred on the
trustee;  provided,  however, that the trustee determines that the action is now
lawful,  or if the trustee in good faith determines that the action would unduly
prejudice  the holders of the debt  securities  not taking part in the action or
would impose personal liability on the trustee. (Section 512)

Each  indenture  provides  that,  in case an event of  default  in  respect of a
particular  series of debt  securities  has occurred,  the trustee is to use the
degree of care of a prudent  person in the conduct of his own affairs.  (Section
602) Subject to such provisions,  the trustee is under no obligation to exercise
any of its  rights or power  under the  indenture  at the  request of any of the
holders of the debt  securities of such series unless they have furnished to the
trustee reasonable security or indemnity. (Section 602)

We will be required to furnish to the trustee in an annual statement a notice as
to our fulfillment of all of our obligations under the relevant indenture.
(Section 1007)

Modification of the Indentures

We must obtain the consent of holders of at least a majority in principal amount
of all  outstanding  debt securities  affected by a change to an indenture.  The
consent of holders of at least a majority in principal  amount of each series of
outstanding  debt securities is required to waive  compliance by us with certain
covenants in the indenture.  We must obtain the consent of each holder  affected
by a change to extend the maturity; reduce the principal,  redemption premium or
interest  rate;  change  the  place of  payment,  or the coin or  currency,  for
payment; limit the right to sue for payment; reduce the level of consents needed
to approve a change to an indenture;  or modify any of the foregoing  provisions
or any of the  provisions  relating  to the waiver of certain  past  defaults or
certain  covenants,  except to increase the required  level of consents  need to
approve a change to an indenture. (Article Nine)

Defeasance

We may  defease  the debt  securities  of a series,  which  means  that we would
satisfy our duties under that series before maturity. We may do so by depositing
with the trustee,  in trust for the benefit of the holders,  sufficient funds to
pay the entire  indebtedness on that series,  including  principal,  premium, if
any, and interest.  Certain other conditions must be met before we may do so. We
must also  deliver an opinion of counsel to the effect  that the holders of that
series will have no federal income tax consequences as a result of that deposit.
(Article Fourteen)

Conversion

Debt  securities may be convertible  into or  exchangeable  for common shares or
preferred  shares.  The  prospectus  supplement  will  describe the terms of any
conversion  rights.  To protect our status as a REIT,  debt  securities  are not
convertible if, as a result of such conversion,  any person would then be deemed
to own, directly or indirectly, more than 9.8% of our capital shares.

Merger, Consolidation and Sale of Assets

Each  indenture  generally  permits  us to  consolidate  or merge  with  another
corporation.  The indentures also permit us to sell all or substantially  all of
our property and assets. If this happens, the remaining or acquiring corporation
shall assume all of our  responsibilities  and liabilities  under the indentures
including the payment of all amounts due on the debt  securities and performance
of the covenants in the indentures.

However, we will only consolidate or merge with or into any other corporation or
sell  all or  substantially  all of  our  assets  according  to  the  terms  and
conditions of the  indentures.  The remaining or acquiring  corporation  will be
substituted  for us in the indentures  with the same effect as if it had been an
original  party to the  indenture.  Thereafter,  the successor  corporation  may
exercise  our rights and powers under any  indenture,  in our name or in its own
name.  Any act or  proceeding  required or  permitted to be done by our board of
trust  managers or any of our  officers  may be done by the board or officers of
the successor corporation. (Article Eight)


                         FEDERAL INCOME TAX CONSEQUENCES


General

The following  summary of material federal income tax  consequences  that may be
relevant  to a holder of common  shares is based on current  law, is for general
information  only and is not intended as tax advice.  The following  discussion,
which is not  exhaustive  of all possible tax  consequences,  does not include a
detailed discussion of any state, local or foreign tax consequences. Nor does it
discuss all of the aspects of federal income  taxation that may be relevant to a
prospective  shareholder in light of his or her particular  circumstances  or to
certain  types  of  shareholders  (including  insurance  companies,   tax-exempt
entities,  financial  institutions or broker-dealers,  foreign  corporations and
persons who are not citizens or residents of the United States and  shareholders
holding securities as part of a conversion transaction, a hedging transaction or
as a  position  in a  straddle  for tax  purposes)  who are  subject  to special
treatment under the federal income tax laws.

The statements in this  discussion  are based on current  provisions of the Code
existing,  temporary and currently proposed Treasury Regulations under the Code,
the  legislative  history  of the  Code,  existing  administrative  rulings  and
practices of the IRS and  judicial  decisions.  No  assurance  can be given that
legislative,  judicial or administrative changes will not affect the accuracy of
any statements in this discussion  with respect to transactions  entered into or
contemplated prior to the effective date of such changes.  Any such change could
apply retroactively to transactions  preceding the date of the change. We do not
plan to request any rulings from the IRS  concerning  our tax  treatment and the
statements in this discussion are not binding on the IRS or any court.  Thus, we
can provide no assurance that these statements will not be challenged by the IRS
or that such challenge will not be sustained by a court.

This  discussion is not intended as a substitute for careful tax planning.  Each
prospective  purchaser of common stock is advised to consult with his or her own
tax  advisor  regarding  the  specific  tax  consequences  to  him or her of the
purchase,  ownership and disposition of common stock in an entity electing to be
taxed as a REIT,  including  the federal,  state,  local,  foreign and other tax
consequences  of such  purchase,  ownership,  disposition  and election,  and of
potential changes in applicable tax laws.

We have  elected to be treated as a REIT under  Sections  856 through 860 of the
Code for federal  income tax  purposes  commencing  with our taxable  year ended
December 31, 1989. We believe that we have been organized and have operated in a
manner that  qualifies  for  taxation as a REIT under the Code.  We also believe
that we will  continue to operate in a manner that will preserve our status as a
REIT. We cannot however,  assure you that such  requirements  will be met in the
future.

We have received an opinion from Locke Liddell & Sapp LLP, our legal counsel, to
the effect that we qualified as a REIT under the Code for our taxable year ended
December 31, 1998,  we have been  organized and our manner of operation has been
in conformity with the requirements for  qualification and taxation as a REIT as
of the date of this  prospectus  and that our proposed  manner of operation  and
diversity  of  equity  ownership  will  enable us to  continue  to  satisfy  the
requirements for qualification as a REIT in the future.  However,  you should be
aware that opinions of counsel are not binding on the IRS or on the courts, and,
if the IRS were to challenge these  conclusions,  no assurance can be given that
these  conclusions  would be sustained in court.  The opinion of Locke Liddell &
Sapp LLP is based on various  assumptions as well as on certain  representations
made by us as to factual  matters,  including  a factual  representation  letter
provided  by us. The rules  governing  REITs are highly  technical  and  require
ongoing  compliance with a variety of tests that depend,  among other things, on
future  operating  results,  asset  diversification,   distribution  levels  and
diversity  of stock  ownership.  Locke  Liddell & Sapp LLP will not  monitor our
compliance with these requirements.  While we expect to satisfy these tests, and
will use our best  efforts  to do so,  no  assurance  can be given  that we will
qualify as a REIT for any  particular  year, or that the applicable law will not
change and adversely affect us and our shareholders.  See "Failure to Qualify as
a  REIT."  The  following  is a  summary  of the  material  federal  income  tax
considerations  affecting  us as a REIT and our  shareholders.  This  summary is
qualified in its entirety by the applicable Code provisions,  relevant rules and
regulations   promulgated  under  the  Code,  and  administrative  and  judicial
interpretations of the Code and these rules and regulations.

REIT Qualification

We must be  organized  as an entity that would,  if we do not  maintain our REIT
status,  be  taxable  as  a  regular  corporation.  We  cannot  be  a  financial
institution  or an  insurance  company.  We must be managed by one or more trust
managers.  Our taxable year must be the calendar year. Our beneficial  ownership
must be evidenced by transferable  shares. Our capital shares must be held by at
least 100  persons  during  at least 335 days of a taxable  year of 12 months or
during a proportionate  part of a taxable year of less than 12 months.  Not more
than 50% of the value of the shares of our capital shares may be held,  directly
or indirectly, applying the applicable constructive ownership rules of the Code,
by five or fewer  individuals  at any time  during  the last half of each of our
taxable years. We must also meet certain other tests, described below, regarding
the nature of our income and assets and the amount of our distributions.

Our outstanding  common shares are owned by a sufficient number of investors and
in  appropriate  proportions  to  permit us to  satisfy  these  share  ownership
requirements.   To  protect   against   violations  of  these  share   ownership
requirements,  our charter provides that no person is permitted to own, applying
constructive  ownership  tests  set  forth in the  Code,  more  than 9.8% of our
outstanding  common shares,  unless the trust managers  (including a majority of
the independent  trust managers) are provided  evidence  satisfactory to them in
their sole discretion that our  qualification as a REIT will not be jeopardized.
In addition,  our charter contains  restrictions on transfers of capital shares,
as well as  provisions  that  automatically  convert  common  shares into excess
securities to the extent that the ownership  otherwise might jeopardize our REIT
status.  These restrictions,  however may not ensure that we will, in all cases,
be able to satisfy the share ownership requirements. If we fail to satisfy these
share  ownership  requirements,  except as  provided in the next  sentence,  our
status as a REIT will terminate.  However, if we comply with the rules contained
in  applicable  Treasury  Regulations  that require us to  ascertain  the actual
ownership of our shares and we do not know,  or would not have known through the
exercise of  reasonable  diligence,  that we failed to meet the 50%  requirement
described  above,  we will be treated as having  met this  requirement.  See the
section below entitled "Failure to Qualify as a REIT."

To monitor our compliance with the share ownership requirements, we are required
to and we do maintain  records  disclosing  the actual  ownership  of our common
shares.  To do so, we will demand written  statements  each year from the record
holders of certain  percentages  of shares in which the  record  holders  are to
disclose the actual owners of the shares (i.e.,  the persons required to include
in gross income the REIT dividends). A list of those persons failing or refusing
to  comply  with  this  demand  will  be  maintained  as  part  of our  records.
Shareholders  who fail or  refuse  to  comply  with  the  demand  must  submit a
statement with their tax returns  disclosing the actual  ownership of the shares
and certain other information.

We  currently  satisfy,  and  expect  to  continue  to  satisfy,  each of  these
requirements  discussed above. We also currently satisfy, and expect to continue
to satisfy,  the requirements that are separately described below concerning the
nature and  amounts of our income and assets and the levels of  required  annual
distributions.

Sources of Gross Income. In order to qualify as a REIT for a particular year, we
also must meet two  tests  governing  the  sources  of our  income - a 75% gross
income test and a 95% gross income test. These tests are designed to ensure that
a REIT derives its income principally from passive real estate investments.  The
Code  allows  a REIT to own and  operate  a  number  of its  properties  through
wholly-owned  subsidiaries  which are "qualified  REIT  subsidiaries."  The Code
provides  that  a  qualified  REIT  subsidiary  is  not  treated  as a  separate
corporation,  and all of its assets,  liabilities and items of income, deduction
and credit are treated as assets, liabilities and items of income of the REIT.

In the case of a REIT which is a partner in a  partnership  or any other  entity
such as a limited liability company that is treated as a partnership for federal
income tax purposes,  Treasury  Regulations provide that the REIT will be deemed
to own its proportionate share of the assets of the partnership.  Also, the REIT
will be deemed to be  entitled to its  proportionate  share of the income of the
partnership.  The  character of the assets and gross  income of the  partnership
retains the same  character in the hands of the REIT for purposes of Section 856
of the Code,  including  satisfying  the gross income tests and the asset tests.
Thus,  our  proportionate  share  of the  assets  and  items  of  income  of any
partnership  in which we own an interest  are treated as our assets and items of
income for purposes of applying the  requirements  described in this discussion,
including the income and asset tests described below.

75% Gross  Income  Test.  At least 75% of a REIT's gross income for each taxable
year must be derived from specified  classes of income that principally are real
estate related. The permitted categories of principal importance to us are:

- -    rents from real property;

- -    interest on loans secured by real property;

- -    again from the sale of real  property  or loans  secured  by real  property
     (excluding  gain  from  the sale of  property  held  primarily  for sale to
     customers  in the  ordinary  course of our  business,  referred to below as
     "dealer property");

- -    income from the  operation  and gain from the sale of property  acquired in
     connection  with the  foreclosure  of a  mortgage  securing  that  property
     ("foreclosure property");

- -    distributions  on,  or gain from the sale of,  shares  of other  qualifying
     REITs;

- -    abatements and refunds of real property taxes;

- -    amounts  received as  consideration  for entering  into  agreements to make
     loans secured by real property or to purchase or lease real property; and

- -    "qualified temporary investment income" (described below).

In evaluating our compliance  with the 75% gross income test, as well as the 95%
gross income test  described  below,  gross income does not include gross income
from  "prohibited  transactions."  In general,  a prohibited  transaction is one
involving a sale of dealer property,  not including foreclosure property and not
including certain dealer property we have held for at least four years.

We  expect  that  substantially  all of  our  operating  gross  income  will  be
considered rent from real property and interest income.  Rent from real property
is  qualifying  income for  purposes of the gross  income  tests only if certain
conditions are satisfied.  Rent from real property includes charges for services
customarily  rendered to tenants,  and rent  attributable  to personal  property
leased together with the real property so long as the personal  property rent is
not more than 15% of the total rent  received or accrued under the lease for the
taxable  year. We do not expect to earn  material  amounts in these  categories.
Rent from real property  generally  does not include rent based on the income or
profits derived from the property.  However, rent based on a percentage of gross
receipt or sales is permitted as rent from real property and we will have leases
where rent is based on a percentage of gross  receipt or sales.  We generally do
not intend to lease property and receive rentals based on the tenant's income or
profit.  Also excluded  from "rents from real  property" is rent received from a
person or corporation in which we (or any of our 10% or greater owners) directly
or indirectly through the constructive  ownership rules contained in Section 318
and Section 856(d)(5) of the Code, own a 10% or greater interest.

A third  exclusion  from  qualifying  rent income covers  amounts  received with
respect to real  property  if we furnish  services  to the  tenants or manage or
operate the property,  other than through an "independent  contractor" from whom
we do not derive any income.  The  obligation to operate  through an independent
contractor  generally  does not apply,  however,  if the services we provide are
"usually or  customarily  rendered" in  connection  with the rental of space for
occupancy only and are not considered  rendered primarily for the convenience of
the tenant (applying  standards that govern in evaluating whether rent from real
property  would  be  unrelated  business  taxable  income  when  received  by  a
tax-exempt owner of the property).  Further,  if the value of the  non-customary
service  income with  respect to a property,  valued at no less than 150% of our
direct  cost of  performing  such  services,  is 1% or less of the total  income
derived from the  property,  then the provision of such  non-customary  services
shall not prohibit the rental income (except the  non-customary  service income)
from qualifying as "rents from real property."

We believe that the only material  services  generally to be provided to tenants
will be those usually or customarily  rendered in connection  with the rental of
space for  occupancy  only.  We do not intend to provide  services that might be
considered rendered primarily for the convenience of the tenants, such as hotel,
health care or  extensive  recreational  or social  services.  Consequently,  we
believe that  substantially  all of our rental income will be qualifying  income
under the gross income tests,  and that our provision of services will not cause
the rental income to fail to be included under that test.

Upon the ultimate sale of our  properties,  any gains realized also are expected
to  constitute  qualifying  income,  as gain from the sale of real property (not
involving a prohibited transaction).

95% Gross Income  Test.  In addition to earning 75% of our gross income from the
sources  listed  above,  95% of our gross income for each taxable year must come
either from those sources, or from dividends, interest or gains from the sale or
other  disposition of stock or other  securities  that do not constitute  dealer
property.  This test permits a REIT to earn a significant  portion of its income
from  traditional  "passive"  investment  sources that are not necessarily  real
estate related.  The term "interest" (under both the 75% and 95% tests) does not
include  amounts  that are based on the income or profits of any person,  unless
the computation is based only on a fixed percentage of receipts or sales.

Failing the 75% or 95% Tests;  Reasonable  Cause. As a result of the 75% and 95%
tests,  REITs  generally  are not  permitted to earn more than 5% of their gross
income from active sources,  including  brokerage  commissions or other fees for
services  rendered.  We may receive  certain types of that income.  This type of
income will not  qualify for the 75% test or 95% test but is not  expected to be
significant  and that  income,  together  with other  nonqualifying  income,  is
expected to be at all times less than 5% of our annual gross income. While we do
not anticipate that we will earn substantial amounts of nonqualifying income, if
nonqualifying income exceeds 5% of our gross income, we could lose our status as
a REIT. We may establish subsidiaries of which we will hold less than 10% of the
voting stock to hold assets generating  non-qualifying  income. The gross income
generated  by these  subsidiaries  would not be  included  in our gross  income.
However,  dividends we receive from these  subsidiaries would be included in our
gross income and qualify for the 95% income test.  The ability to establish such
subsidiaries  could be adversely  impacted by  proposals  contained in President
Clinton's 2000 Federal Budget Proposal. See the section below entitled "Proposed
Legislation."

If we fail to meet either the 75% or 95% income tests during a taxable  year, we
may still qualify as a REIT for that year if (1) we report the source and nature
of each item of our gross income in our federal income tax return for that year,
(2) the inclusion of any incorrect information in our return is not due to fraud
with  intent  to evade  tax,  and (3) the  failure  to meet the  tests is due to
reasonable cause and not to willful  neglect.  It is not possible,  however,  to
state whether in all  circumstances  we would be entitled to the benefit of this
relief  provision.  For  example,  if we fail to satisfy the gross  income tests
because  nonqualifying  income that we intentionally accrue or receive causes us
to exceed the limits on  nonqualifying  income,  the IRS could conclude that our
failure to satisfy the tests was not due to  reasonable  cause.  If these relief
provisions  do not  apply  to a  particular  set of  circumstances,  we will not
qualify as a REIT. As discussed below,  even if these relief  provisions  apply,
and we retain our status as a REIT,  a tax would be imposed  with respect to our
non-qualifying income. We would be subject to a 100% tax based on the greater of
the amount by which we fail either the 75% or 95% income tests for that year.
See "-- Taxation as a REIT."

Prohibited  Transaction  Income.  Any gain  that we  realize  on the sale of any
property  held as  inventory  or  other  property  held  primarily  for  sale to
customers in the ordinary  course of business  (including  our share of any such
gain realized by any subsidiary partnerships),  will be treated as income from a
prohibited  transaction  that is subject to a 100% penalty tax. This  prohibited
transaction  income may also adversely  affect our ability to satisfy the income
tests for  qualification as a REIT. Under existing law, whether property is held
as  inventory or  primarily  for sale to  customers in the ordinary  course of a
trade or business  depends on all the facts and  circumstances  surrounding  the
particular  transaction.  We intend to hold our and our subsidiary  partnerships
intend  to  hold  their  properties  for  investment  with a view  to  long-term
appreciation,  to engage in the  business of  acquiring,  developing  and owning
properties,  and to make  occasional  sales of the  properties as are consistent
with their investment objectives. The IRS may contend, however, that one or more
of these sales is subject to the 100% penalty tax.

Character of Assets Owned. At the close of each calendar  quarter of our taxable
year,  we also must meet two tests  concerning  the  nature of our  investments.
First,  at least 75% of the value of our total assets  generally must consist of
real estate assets,  cash,  cash items  (including  receivables)  and government
securities.  For this purpose,  "real estate assets"  include  interests in real
property, interests in loans secured by mortgages on real property or by certain
interests  in real  property,  shares in other  REITs and certain  options,  but
excluding mineral, oil or gas royalty interests. The temporary investment of new
capital in debt  instruments  also qualifies under this 75% asset test, but only
for the  one-year  period  beginning  on the date we  receive  the new  capital.
Second,  although the balance of our assets  generally  may be invested  without
restriction,  we  will  not  be  permitted  to own  (1)  securities  of any  one
non-governmental  issuer that  represent  more than 5% of the value of our total
assets or (2) more than 10% of the outstanding  voting  securities of any single
issuer.  A  REIT,  however,  may own  100%  of the  stock  of a  qualified  REIT
subsidiary, in which case the assets, liabilities and items of income, deduction
and credit of the  subsidiary  are treated as those of the REIT. In evaluating a
REIT's  assets,  if the REIT invests in a  partnership,  it is deemed to own its
proportionate share of the assets of the partnership.

After initially meeting the asset tests at the close of any quarter, we will not
lose our status as a REIT for failure to satisfy the asset tests at the end of a
later quarter solely by reason of changes in asset values. If we fail to satisfy
the asset  tests  because  we  acquire  securities  or other  property  during a
quarter,  we can cure this  failure by  disposing  of  sufficient  nonqualifying
assets  within 30 days after the close of that  quarter.  We intend to take such
action  within the 30 days after the close of any  quarter as may be required to
cure any  noncompliance.  If we fail to cure  noncompliance with the asset tests
within this time period, we would cease to qualify as a REIT.

Annual Distributions to Shareholders.  To maintain our REIT status, we generally
must distribute as a dividend to our  shareholders in each taxable year at least
95% of our net ordinary income.  Capital gain is not required to be distributed.
More precisely,  we must distribute an amount equal to (1) 95% of the sum of (a)
our "REIT Taxable  Income" before  deduction of dividends paid and excluding any
net capital gain and (b) any net income from  foreclosure  property less the tax
on such income, minus (2) certain limited categories of "excess noncash income,"
including,  income  attributable  to  leveled  stepped  rents,  cancellation  of
indebtedness and original issue discount income.  REIT Taxable Income is defined
to be the  taxable  income  of the  REIT,  computed  as if it were  an  ordinary
corporation,  with  certain  modifications.   For  example,  the  deduction  for
dividends paid is allowed, but neither net income from foreclosure property, nor
net income from prohibited transactions,  is included. In addition, the REIT may
carry over, but not carry back, a net operating loss for 20 years  following the
year in which it was incurred.

A REIT may  satisfy the 95%  distribution  test with  dividends  paid during the
taxable year and with certain  dividends paid after the end of the taxable year.
Dividends paid in January that were declared during the last calendar quarter of
the prior year and were payable to  shareholders  of record on a date during the
last  calendar  quarter of that prior year are treated as paid on December 31 of
the prior year.  Other dividends  declared before the due date of our tax return
for the taxable year, including extensions,  also will be treated as paid in the
prior year if they are paid (1) within 12 months of the end of that taxable year
and (2) no later than our next regular distribution payment.  Dividends that are
paid  after  the  close of a taxable  year  that do not  qualify  under the rule
governing  payments  made in January  (described  above)  will be taxable to the
shareholders  in the year paid,  even though we may take them into account for a
prior  year.  A  nondeductible  excise tax equal to 4% will be imposed  for each
calendar year to the extent that  dividends  declared and  distributed or deemed
distributed before December 31 are less than the sum of (a) 85% of our "ordinary
income" plus (b) 95% of our capital  gain net income plus (c) any  undistributed
income from prior periods.

To be entitled to a dividends paid deduction,  the amount  distributed by a REIT
must not be preferential.  For example, every shareholder of the class of shares
to  which a  distribution  is made  must be  treated  the  same as  every  other
shareholder of that class, and no class of shares may be treated  otherwise than
in accordance with its dividend rights as a class.

We will be taxed at regular  corporate  rates to the  extent  that we retain any
portion of our taxable income.  For example,  if we distribute only the required
95% of our taxable  income,  we would be taxed on the retained 5%. Under certain
circumstances we may not have sufficient cash or other liquid assets to meet the
distribution requirement.  This could arise because of competing demands for our
funds, or due to timing differences  between tax reporting and cash receipts and
disbursements (i.e., income may have to be reported before cash is received,  or
expenses may have to be paid before a deduction is allowed).  Although we do not
anticipate any difficulty in meeting this requirement, no assurance can be given
that  necessary  funds will be available.  In the event these  circumstances  do
occur, then in order to meet the 95% distribution requirement,  we may cause our
operating  partnership  to  arrange  for  short-term,   or  possibly  long-term,
borrowings to permit the payment of required dividends.

If we fail to meet the 95% distribution  requirement because of an adjustment to
our taxable income by the IRS, we may be able to cure the failure  retroactively
by paying a "deficiency dividend," as well as applicable interest and penalties,
within a specified period.

Taxation as a REIT

As a REIT,  we  generally  will not be  subject to  corporate  income tax to the
extent we currently distribute our REIT taxable income to our shareholders. This
treatment effectively eliminates the "double taxation" imposed on investments in
most  corporations.  Double  taxation refers to taxation that occurs once at the
corporate  level when income is earned and once again at the  shareholder  level
when such income is distributed.  We generally will be taxed only on the portion
of our taxable income that we retain,  which will include any  undistributed net
capital gain,  because we will be entitled to a deduction for dividends  paid to
shareholders  during  the  taxable  year.  A  dividends  paid  deduction  is not
available for dividends that are considered  preferential within any given class
of shares or as between classes except to the extent that class is entitled to a
preference.  We do not  anticipate  that we will pay any of  those  preferential
dividends.  Because excess shares will represent a separate class of outstanding
shares,  the fact that those shares will not be entitled to dividends should not
adversely affect our ability to deduct our dividend payments.

Even as a REIT, we will be subject to tax in certain circumstances as follows:

o    we would be subject to tax on any income or gain from foreclosure  property
     at the highest  corporate rate  (currently  35%).  Foreclosure  property is
     generally  defined as  property  acquired  through  foreclosure  or after a
     default on a loan secured by the property or a lease of the property;

o    a  confiscatory  tax of 100%  applies  to any net  income  from  prohibited
     transactions which are, in general,  certain sales or other dispositions of
     property  held  primarily  for sale to customers in the ordinary  course of
     business;

o    if we fail to meet either the 75% or 95% source of income  tests  described
     above,  but  still  qualify  for REIT  status  under the  reasonable  cause
     exception to those tests,  a 100% tax would be imposed  equal to the amount
     obtained by multiplying (a) the greater of the amount,  if any, by which it
     failed  either the 75%  income  test or the 95%  income  test,  times (b) a
     fraction intended to reflect our profitability;

o    we  will  be  subject  to  the  alternative  minimum  tax on  items  of tax
     preference, excluding items specifically allocable to our shareholders;

o    if we should fail to distribute with respect to each calendar year at least
     the sum of (a) 85% of our REIT  ordinary  income for that year,  (b) 95% of
     our REIT capital gain net income for that year,  and (c) any  undistributed
     taxable income from prior years,  we would be subject to a 4% excise tax on
     the  excess  of  the  required   distribution  over  the  amounts  actually
     distributed;

o    under  regulations that are to be promulgated,  we also may be taxed at the
     highest  regular  corporate tax rate on any built-in gain  attributable  to
     assets that we acquire in certain tax-free corporate  transactions,  to the
     extent the gain is  recognized  during the first ten years after we acquire
     those  assets.  Built-in gain is the excess of (a) the fair market value of
     the asset over (b) our adjusted basis in the asset, in each case determined
     as of the  beginning  of  the  ten-year  recognition  period.  The  results
     described in this  paragraph  with respect to the  recognition  of built-in
     gain assume that we will make an election  pursuant to IRS Notice 88-19 and
     that the  availability  or  nature  of such  election  is not  modified  as
     proposed in President  Clinton's  2000  Federal  Budget  Proposal.  See the
     section below entitled "Proposed Legislation"; and

o    we will be taxed at  regular  corporate  rates  on any  undistributed  REIT
     taxable income, including undistributed net capital gains.

Failure to Qualify as a REIT

For any taxable  year in which we fail to qualify as a REIT and  certain  relief
provisions do not apply, we would be taxed at regular corporate rates, including
alternative minimum tax rates on all of our taxable income. Distributions to our
shareholders  would not be  deductible  in computing  that taxable  income,  and
distributions  would no longer be required to be made. Any corporate level taxes
generally  would reduce the amount of cash  available  for  distribution  to our
shareholders  and,  because the  shareholders  would continue to be taxed on the
distributions  they receive,  the net after tax yield to the  shareholders  from
their investment likely would be reduced substantially.  As a result, failure to
qualify as a REIT during any taxable year could have a material  adverse  effect
on an  investment  in our  common  shares.  If we lose our REIT  status,  unless
certain relief  provisions  apply, we would not be eligible to elect REIT status
again until the fifth  taxable  year which  begins after the taxable year during
which our election was  terminated.  It is not possible to state  whether in all
circumstances  we would be  entitled  to this  statutory  relief.  In  addition,
President  Clinton's 2000 Federal Budget Proposal contains a provision which, if
enacted in its present form, would result in the immediate  taxation of all gain
inherent in a C  corporation's  assets upon an  election by the  corporation  to
become a REIT in taxable years beginning after January 1, 2000. If enacted, this
provision could  effectively  preclude us from re-electing to be taxed as a REIT
following  a loss of REIT  status.  See the  section  below  entitled  "Proposed
Legislation."

Taxation of Taxable U.S. Shareholders

Except as discussed  below,  distributions  generally will be taxable to taxable
U.S. shareholders as ordinary income to the extent of our current or accumulated
earnings and profits. We may generate cash in excess of our net earnings.  If we
distribute cash to shareholders in excess of our current and accumulated capital
earnings and profits  (other than as a capital gain  dividend),  the excess cash
will be deemed to be a return of  capital to each  shareholder  to the extent of
the adjusted tax basis of the shareholder's  shares.  Distributions in excess of
the  adjusted tax basis will be treated as gain from the sale or exchange of the
shares.  A shareholder  who has received a distribution in excess of current and
our accumulated earnings and profits may, upon the sale of the shares, realize a
higher taxable gain or a smaller loss because the basis of the shares as reduced
will be  used  for  purposes  of  computing  the  amount  of the  gain or  loss.
Distributions  we make,  whether  characterized as ordinary income or as capital
gains, are not eligible for the dividends  received  deduction for corporations.
For purposes of determining  whether  distributions  to holders of common shares
are out of current or accumulated earnings and profits, our earnings and profits
will be allocated first to the outstanding preferred shares, if any, and then to
the common shares.

Dividends we declare in October,  November,  or December of any year and payable
to a shareholder  of record on a specified  date in any of these months shall be
treated as both paid by us and  received  by the  shareholder  on December 31 of
that year,  provided we actually pay the dividend on or before January 31 of the
following  calendar year.  Shareholders  may not include in their own income tax
returns any of our net operating losses or capital losses.

Distributions  that we properly  designate  as capital  gain  dividends  will be
taxable to taxable U.S.  shareholders as gains from the sale or disposition of a
capital  asset to the extent that they do not exceed our actual net capital gain
for the taxable year. Depending on the period of time the tax characteristics of
the assets which  produced  these gains,  and on certain  designations,  if any,
which we may make, these gains may be taxable to non-corporate U.S. shareholders
at a 20% or 25% rate. U.S.  shareholders that are corporations may, however,  be
required  to treat up to 20% of  certain  capital  gain  dividends  as  ordinary
income.

We may elect to retain,  rather than distribute as a capital gain dividend,  our
net long-term  capital gains. If we make this election,  we would pay tax on our
retained net long-term capital gains. In addition, to the extent we designate, a
U.S. shareholder generally would:

o    include its  proportionate  share of our  undistributed  long-term  capital
     gains in  computing  its  long-term  capital  gains in its  return  for its
     taxable year in which the last day of our taxable year falls;

o    be  deemed  to  have  paid  the  capital  gains  tax  imposed  on us on the
     designated  amounts included in the U.S.  shareholder's  long-term  capital
     gains;

o    receive a credit or refund for the amount of tax deemed paid by it;

o    increase the adjusted basis of its common stock by the  difference  between
     the amount of includable  gains and the tax deemed to have been paid by it;
     and

o    in the  case of a U.S.  shareholder  that is a  corporation,  appropriately
     adjust  its  earnings  and  profits  for  the  retained  capital  gains  in
     accordance with Treasury Regulations to be prescribed by the IRS.

Distributions  we make and gain  arising  from  the sale or  exchange  by a U.S.
shareholder of our shares will not be treated as income from a passive activity,
within the  meaning  of Section  469 of the Code,  since  income  from a passive
activity  generally  does not include  dividends  and gain  attributable  to the
disposition of property that produces dividends.  As a result, U.S. shareholders
subject to the  passive  activity  rules will  generally  be unable to apply any
"passive  losses"  against this income or gain.  Distributions  we make,  to the
extent they do not constitute a return of capital,  generally will be treated as
investment income for purposes of computing the investment interest  limitation.
Gain arising from the sale or other disposition of our shares, however, will not
be treated as investment income under certain circumstances.

Generally,  gain or loss realized by a shareholder  upon the sale of shares will
be reportable  as capital gain or loss.  If a  shareholder  receives a long-term
capital  gain  dividend  from us and has held the shares for six months or less,
any  loss  incurred  on the sale or  exchange  of the  shares  is  treated  as a
long-term capital loss to the extent of the corresponding long-term capital gain
dividend received.

In any year in which we fail to qualify as a REIT,  the  shareholders  generally
will  continue to be treated in the same fashion  described  above,  except that
none of our dividends will be eligible for treatment as capital gains dividends,
corporate shareholders will qualify for the dividends received deduction and the
shareholders  will not be  required  to report  any share of our tax  preference
items.

Proposed Legislation

The rules dealing with Federal income  taxation are  constantly  under review by
Congress, the IRS and the Treasury Department. For example, on February 1, 1999,
President  Clinton  released a proposed  budget for fiscal year 2000. The budget
proposal  contained a variety of  proposed  income tax  changes,  three of which
pertain to REITs.  First,  under current law, REITs may not own more than 10% of
the voting stock of a regular corporation.  Under the proposal,  they also would
not be  permitted to own more than 10% of the value of all classes of stock of a
corporation   unless  the  corporation   qualified  as  a  "qualified   business
subsidiary" or a "qualified independent  contractor  subsidiary." Even if it did
so qualify, the proposal would disallow a deduction for all interest payments on
debt to, or guaranteed  by, a REIT that owns stock of such entities.  Second,  a
new restriction would be imposed on REITs, prohibiting any one person other than
a REIT  from  owning  more than 50% of the total  combined  voting  power of all
voting  stock or more than 50% of the total  value of shares of all  classes  of
stock  of  the  REIT.  Current  law  already  contains  ownership   restrictions
applicable to  individuals;  this new limitation  would affect owners other than
individuals.  This proposal would be effective for entities electing REIT status
for taxable  years  beginning  on or after the date of first  committee  action.
Third, a regular C corporation  with a fair market value of more than $5,000,000
which  elects  REIT  status or merges  into a REIT would be treated as if it had
liquidated  and  distributed  all  its  assets  to  its  shareholders,  and  its
shareholders  had then  contributed the assets to the electing or existing REIT.
This deemed liquidation would cause the regular corporation to be taxed as if it
had sold its assets for fair market value and would cause its shareholders to be
taxed as if they had sold their stock for fair market value.  The proposal would
be effective for elections that are first effective for a taxable year beginning
after  January 1, 2000,  and for mergers  into REITs after  December  31,  1999.
Changes to the Federal laws and  interpretations  thereof could adversely affect
the tax  consequences  of an investment in our common shares.  We cannot predict
whether,  when, in what forms, or with what effective dates,  these or any other
provisions could become effective.

Backup Withholding

We will  report to our  shareholders  and the IRS the amount of  dividends  paid
during  each  calendar  year  and the  amount  of tax  withheld,  if  any.  If a
shareholder is subject to backup withholding,  we will be required to deduct and
withhold from any  dividends  payable to that  shareholder  a tax of 31%.  These
rules  may  apply (1) when a  shareholder  fails to  supply a  correct  taxpayer
identification  number,  (2) when the IRS  notifies us that the  shareholder  is
subject  to the rules or has  furnished  an  incorrect  taxpayer  identification
number,  or (3) in the case of  corporations  or others  within  certain  exempt
categories, when they fail to demonstrate that fact when required. A shareholder
that does not  provide  a correct  taxpayer  identification  number  may also be
subject  to  penalties  imposed  by the  IRS.  Any  amount  withheld  as  backup
withholding  may be  credited  against  the  shareholder's  federal  income  tax
liability.  We also may be  required  to  withhold  a portion  of  capital  gain
distributions made to shareholders who fail to certify their non-foreign status.

The United States Treasury has recently issued final  regulations  regarding the
withholding and information  reporting  rules discussed  above. In general,  the
final  regulations  do not alter the  substantive  withholding  and  information
reporting  requirements but unify current  certification  procedures and clarify
reliance  standards.  The final regulations are generally effective for payments
made  on or  after  January  1,  2000,  subject  to  certain  transition  rules.
Prospective  investors  should  consult  their own tax advisors  concerning  the
adoption of the final regulations and the potential effect on their ownership of
common shares.

Taxation of Tax-Exempt Entities

In general, a tax-exempt entity that is a shareholder will not be subject to tax
on  distributions  or gain  realized  on the sale of shares.  In Revenue  Ruling
66-106, the IRS confirmed that a REIT's distributions to a tax-exempt employees'
pension trust did not constitute  unrelated  business  taxable income,  commonly
known as "UBTI." A  tax-exempt  entity may be subject to UBTI,  however,  to the
extent that it has  financed  the  acquisition  of its shares with  "acquisition
indebtedness" within the meaning of the Code. The Revenue  Reconciliation Act of
1993 has modified the rules for tax-exempt employees' pension and profit sharing
trusts which qualify  under  Section  401(a) of the Code and are exempt from tax
under Section 501(a) of the Code  ("qualified  trusts") for tax years  beginning
after  December 31, 1993. In determining  the number of  shareholders a REIT has
for purposes of the "50% test"  described  above under  "--REIT  Qualification,"
generally, any shares held by a qualified trust will be treated as held directly
by its  beneficiaries in proportion to their interests in the trust and will not
be treated as held by the trust.

A  qualified  trust  owning  more than 10% of a REIT may be  required to treat a
percentage of dividends  from the REIT as UBTI.  The percentage is determined by
dividing the REIT's gross income (less direct expenses  related thereto) derived
from an unrelated trade or business for the year (determined as if the REIT were
a  qualified  trust) by the  gross  income of the REIT for the year in which the
dividends are paid.  However,  if this percentage is less than 5%, dividends are
not treated as UBTI. These UBTI rules apply only if the REIT qualifies as a REIT
because  of the  change  in the 50% test  discussed  above  and if the  trust is
"predominantly  held"  by  qualified  trusts.  A REIT is  predominantly  held by
qualified  trusts if at least one pension  trust owns more than 25% of the value
of the REIT or a group of pension  trusts each owning more than 10% of the value
of the REIT  collectively  own more than 50% of the value of the REIT. We do not
currently meet either of these requirements.

For  social  clubs,   voluntary  employee  benefit  associations,   supplemental
unemployment benefit trusts and qualified group legal services plans exempt from
federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of
the Code,  respectively,  income from an  investment  in our capital  stock will
constitute UBTI unless the organization is able to deduct an amount properly set
aside or  placed in  reserve  for  certain  purposes  so as to  offset  the UBTI
generated by the investment in our capital stock.  These  prospective  investors
should  consult  their own tax advisors  concerning  the "set aside" and reserve
requirements.

Taxation of Foreign Investors

The rules governing  federal income taxation of nonresident  alien  individuals,
foreign  corporations,  foreign  partnerships and other foreign shareholders are
complex  and no attempt  will be made  herein to provide  more than a summary of
such rules. Prospective non-U.S.  shareholders should consult with their own tax
advisors to  determine  the impact of federal,  state and local  income tax laws
with  regard  to  an  investment  in  common  shares,  including  any  reporting
requirements,  as well as the tax treatment of such an investment under the laws
of their home country.

Dividends that are not  attributable to gain from any sales or exchanges we make
of United  States  real  property  interests  and which we do not  designate  as
capital gain  dividends  will be treated as dividends of ordinary  income to the
extent  that  they are made  out of our  current  or  accumulated  earnings  and
profits.  Those dividends  ordinarily will be subject to a withholding tax equal
to 30% of the gross  amount of the  dividend  unless an  applicable  tax  treaty
reduces or eliminates  that tax.  However,  if income from the investment in the
common   shares  is  treated  as   effectively   connected   with  the  non-U.S.
shareholder's  conduct  of a United  States  trade  or  business,  the  non-U.S.
shareholder  generally will be subject to a tax at graduated  rates, in the same
manner as U.S.  shareholders are taxed with respect to those dividends,  and may
also be subject to the 30% branch profits tax in the case of a shareholder  that
is a  foreign  corporation.  For  withholding  tax  purposes,  we are  currently
required  to  treat  all  distributions  as if  made  out  of  our  current  and
accumulated  earnings  and profits and thus we intend to withhold at the rate of
30%, or a reduced treaty rate if applicable,  on the amount of any  distribution
(other  than  distributions  designated  as capital  gain  dividends)  made to a
non-U.S.  shareholder unless (1) the non-U.S. shareholder files on IRS Form 1001
claiming that a lower treaty rate applies or (2) the non-U.S.  shareholder files
an IRS Form 4224 claiming that the dividend is effectively connected income.

Under the final regulations,  generally  effective for distributions on or after
January  1,  2000,  we would  not be  required  to  withhold  at the 30% rate on
distributions  we  reasonably  estimate  to be in  excess  of  our  current  and
accumulated  earnings  and  profits.  Dividends  in  excess of our  current  and
accumulated  earnings  and profits will not be taxable to a  shareholder  to the
extent that they do not exceed the adjusted basis of the  shareholder's  shares,
but rather will reduce the adjusted  basis of those  shares.  To the extent that
those dividends  exceed the adjusted basis of a non-U.S.  shareholder's  shares,
they will give rise to tax liability if the non-U.S. shareholder would otherwise
be subject to tax on any gain from the sale or  disposition  of his  shares,  as
described  below.  If it cannot be  determined  at the time a  dividend  is paid
whether or not a dividend will be in excess of current and accumulated  earnings
and profits, the dividend will be subject to such withholding.  We do not intend
to make  quarterly  estimates of that portion of dividends that are in excess of
earnings and profits,  and, as a result,  all dividends  will be subject to such
withholding.  However,  the  non-U.S.  shareholder  may seek a  refund  of those
amounts from the IRS.

For any year in which we qualify as a REIT,  distributions that are attributable
to gain from our sales or exchanges  of United  States real  property  interests
will be taxed to a non-U.S.  shareholder  under the  provisions  of the  Foreign
Investment in Real Property Tax Act of 1980,  commonly known as "FIRPTA."  Under
FIRPTA, those dividends are taxed to a non-U.S.  shareholder as if the gain were
effectively connected with a United States business. Non-U.S. shareholders would
thus be taxed at the normal capital gain rates  applicable to U.S.  shareholders
subject to applicable  alternative minimum tax and a special alternative minimum
tax in the case of nonresident  alien  individuals.  Also,  dividends subject to
FIRPTA may be subject to a 30% branch  profits  tax in the hands of a  corporate
non-U.S.  shareholder not entitled to treaty  exemption.  We are required by the
Code and  applicable  Treasury  Regulations to withhold 35% of any dividend that
could be  designated  as a capital  gain  dividend.  This  amount is  creditable
against the non-U.S. shareholder's FIRPTA tax liability.

Gain recognized by a non-U.S.  shareholder  upon a sale of shares generally will
not be taxed under FIRPTA if we are a  "domestically  controlled  REIT," defined
generally as a REIT in which at all times during a specified testing period less
than 50% in value of the  shares  was held  directly  or  indirectly  by foreign
persons. It is currently anticipated that we will be a "domestically  controlled
REIT," and  therefore  the sale of shares will not be subject to taxation  under
FIRPTA. Because the common shares will be publicly traded, however, no assurance
can be given that we will remain a "domestically controlled REIT." However, gain
not  subject  to  FIRPTA  will  be  taxable  to a  non-U.S.  shareholder  if (1)
investment  in the common  shares is  effectively  connected  with the  non-U.S.
shareholder's  United  States  trade or  business,  in which  case the  non-U.S.
shareholder  will be subject to the same  treatment  as U.S.  shareholders  with
respect to that gain,  and may also be subject to the 30% branch  profits tax in
the case of a corporate non-U.S. shareholder, or (2) the non-U.S. shareholder is
a nonresident alien individual who was present in the United States for 183 days
or more during the taxable  year and has a "tax home" in the United  States,  in
which case the nonresident alien individual will be subject to a 30% withholding
tax on the individual's capital gains. If we were not a domestically  controlled
REIT, whether or not a non-U.S. shareholder's sale of shares would be subject to
tax under FIRPTA would depend on whether or not the common shares were regularly
traded on an established securities market (such as the NYSE) and on the size of
selling non-U.S.  shareholder's  interest in our capital shares.  If the gain on
the sale of shares were to be subject to taxation  under  FIRPTA,  the  non-U.S.
shareholder  will be subject to the same  treatment  as U.S.  shareholders  with
respect  to that gain  (subject  to  applicable  alternative  minimum  tax and a
special  alternative  minimum tax in the case of nonresident alien  individuals)
and the  purchaser  of our common  shares may be required to withhold 10% of the
gross purchase price.

State and Local Taxes

We, and our  shareholders,  may be subject to state or local taxation in various
state  or local  jurisdictions,  including  those  in which it or they  transact
business or reside. Consequently,  prospective shareholders should consult their
own tax  advisors  regarding  the  effect  of  state  and  local  tax laws on an
investment in our capital shares.


                              PLAN OF DISTRIBUTION

We may offer securities directly or through underwriters, dealers or agents. The
prospectus  supplement will identify those  underwriters,  dealers or agents and
will describe the plan of distribution,  including commissions to be paid. If we
do not name a firm in the  prospectus  supplement,  the firm may not directly or
indirectly participate in any underwriting of those securities,  although it may
participate in the distribution of securities under  circumstances  entitling it
to a dealer's allowance or agent's commission.  Any underwriting  agreement will
entitle the underwriters to  indemnification  against certain civil  liabilities
under the federal  securities laws and other laws. The nderwriters'  obligations
to purchase  securities will be subject to certain conditions and generally will
require  them to purchase all of the  securities  if any are  purchased.  Unless
otherwise noted in the prospectus supplement,  the securities will be offered by
the  underwriters,  if any,  when,  as and if  issued  by us,  delivered  to and
accepted by the  underwriters  and  subject to their  right to reject  orders in
whole or in part.

We may sell securities to dealers, as principals.  Those dealers then may resell
the securities to the public at varying prices set by those dealers from time to
time. We may also offer  securities  through agents.  Agents  generally act on a
"best  efforts"  basis  during  their  appointment,  meaning  that  they are not
obligated to purchase securities.

Dealers and agents may be  entitled to  indemnification  as  underwriters  by us
against certain liabilities under the Federal securities laws and other laws. We
or the underwriters or the agent may solicit offers by institutions  approved by
us to  purchase  securities  under  contracts  providing  for  further  payment.
Permitted   institutions   include  commercial  and  savings  banks,   insurance
companies,  pension  funds,  investment  companies,  educational  and charitable
institutions  and  others.  Certain  conditions  apply  to those  purchases.  An
underwriter  may  engage  in  over-allotment,  stabilizing  transactions,  short
covering transactions and penalty bids in accordance with Regulation M under the
Securities Exchange Act of 1934.  Over-allotment involves sales in excess of the
offering size, which creates a short position.  Stabilizing  transactions permit
bidders to purchase the underlying  security so long as the stabilizing  bids do
not exceed a specified maximum. Short covering transactions involve purchases of
the securities in the open market after the  distribution  is completed to cover
short  positions.  Penalty  bids  permit the  underwriters  to reclaim a selling
concession  from a dealer when the securities  originally sold by the dealer are
purchased in a covering  transaction to cover short positions.  Those activities
may cause the price of the  securities to be higher than it would  otherwise be.
The  underwriters  may engage in any such  activities  on any  exchange or other
market in which the securities may be traded. If commenced, the underwriters may
discontinue those activities at any time.

The prospectus supplement or pricing supplement,  as applicable,  will set forth
the anticipated delivery date of the securities being sold at that time.


                                  LEGAL MATTERS

Unless otherwise noted in a supplement, Locke Liddell & Sapp LLP, Dallas, Texas,
will pass on the legality of the securities offered through this prospectus.

Counsel  for  any  underwriters  or  agents  will  be  noted  in the  applicable
prospectus supplement.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Subsection  (B) of  Section  9.20 of the Texas Real  Estate  Investment
Trust Act, as amended (the "Act"),  empowers a real estate  investment  trust to
indemnify any person who was, is, or is threatened to be made a named  defendant
or  respondent  in any  threatened,  pending,  or  completed  action,  suit,  or
proceeding,   whether   civil,   criminal,   administrative,   arbitrative,   or
investigative, any appeal in such an action, suit, or proceeding, or any inquiry
or investigation that can lead to such an action, suit or proceeding because the
person is or was a trust manager,  officer, employee or agent of the real estate
investment  trust  or is or was  serving  at the  request  of  the  real  estate
investment  trust as a trust  manager,  director,  officer,  partner,  venturer,
proprietor,  trustee,  employee,  agent, or similar  functionary of another real
estate  investment  trust,   corporation,   partnership,   joint  venture,  sole
proprietorship,  trust,  employee  benefit  plan,  or other  enterprise  against
expenses (including court costs and attorney fees), judgments,  penalties, fines
and  settlements if he conducted  himself in good faith and reasonably  believed
his  conduct  was in or not  opposed to the best  interests  of the real  estate
investment trust and, in the case of any criminal proceeding,  had no reasonable
cause to believe that his conduct was unlawful.

         The Act further provides that, except to the extent otherwise permitted
by the Act, a person may not be  indemnified in respect of a proceeding in which
the person is found  liable on the basis that  personal  benefit was  improperly
received  by him or in which  the  person  is found  liable  to the real  estate
investment trust.  Indemnification pursuant to Subsection (B) of Section 9.20 of
the Act is limited to reasonable  expenses actually incurred and may not be made
in respect  of any  proceeding  in which the  person  has been found  liable for
willful or  intentional  misconduct in the  performance  of his duty to the real
estate investment trust.

         Subsection  (C) of  Section  15.10  of the  Act  provides  that a trust
manager  shall not be liable for any claims or damages  that may result from his
acts in the  discharge  of any duty imposed or power  conferred  upon him by the
real estate  investment trust, if, in the exercise of ordinary care, he acted in
good faith and in reliance upon information,  opinions,  reports, or statements,
including  financial  statements and other financial  data,  concerning the real
estate  investment  trust,  that were  prepared  or  presented  by  officers  or
employees  of  the  real  estate   investment  trust,   legal  counsel,   public
accountants,  investment bankers, or certain other professionals, or a committee
of trust  manager of which the trust  manager is not a member.  In addition,  no
trust manager shall be liable to the real estate  investment  trust for any act,
omission, loss, damage, or expense arising from the performance of his duty to a
real estate investment trust, save only for his own willful misfeasance, willful
malfeasance or gross negligence.

         Article Sixteen of our First Amended and Restated  Declaration of Trust
provides  that we shall  indemnify  officers  and trust  managers,  as set forth
below:

                  (a) We shall  indemnify  every person who is or was serving as
         our trust  manager or officer  and any person who is or was  serving at
         our request as a trust manager, officer, partner, venturer, proprietor,
         trustee,  employee, agent or similar functionary of another real estate
         investment  trust,  partnership,  joint venture,  sole  proprietorship,
         trust,  employee  benefit plan or other  enterprise with respect to all
         costs and  expenses  incurred by such person as a result of such person
         being made or  threatened  to be made a defendant  or  respondent  in a
         proceeding  by reason of his  holding or having  held a position  named
         above in this paragraph.

                  (b) If the indemnification provided in paragraph (a) is either
         (i) insufficient to cover all costs and expenses incurred by any person
         named  in such  paragraph  as a result  of such  person  being  made or
         threatened  to be made a defendant or  respondent  in a  proceeding  by
         reason of his holding or having held a position named in such paragraph
         or (ii) not permitted by Texas law, we shall indemnify,  to the fullest
         extent that indemnification is permitted by Texas law, every person who
         is or was serving as our trust manager or officer and any person who is
         or was serving at our  request as a trust  manager,  officer,  partner,
         venturer,  proprietor,  trustee, employee, agent or similar functionary
         of another real estate  investment trust,  partnership,  joint venture,
         sole proprietorship,  trust,  employee benefit plan or other enterprise
         with  respect to all costs and  expenses  incurred  by such person as a
         result of such person being made or  threatened  to be made a defendant
         or respondent in a proceeding by reason of his holding or having held a
         position named above in this paragraph.

ITEM 17. UNDERTAKINGS.

    The undersigned registrant hereby undertakes as follows:

         (a)(1) To file,  during any  period in which  offers or sales are being

material  information  with respect to the plan of  distribution  not previously
disclosed  in  the  registration  statement  or  any  material  change  to  such
information in the registration statement;

provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) herein do not apply
if the  information  required to be included in a  post-effective  amendment  by
those  paragraphs  is contained  in periodic  reports  filed by the  undersigned
registrant  pursuant to Section 13 or Section 15(d) of the Exchange Act that are
incorporated by reference in the registration statement.

         (2) That,  for the  purpose  of  determining  any  liability  under the
Securities Act, each such  post-effective  amendment shall be deemed to be a new
registration  statement  relating to the  securities  offered  therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (b) The undersigned  registrant hereby undertakes that, for purposes of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
registrant's  annual  report  pursuant to Section 13(a) or 15(d) of the Exchange
act (and,  where  applicable,  each filing of an employee  benefit plan's annual
report  pursuant to Section 15(d) of the Exchange Act) that is  incorporated  by
reference in the registration statement shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

         (c) The undersigned  Registrant hereby further undertakes to supplement
the applicable prospectus  supplement,  after the expiration of the subscription
period, to set forth the results of the subscription  offer, the transactions by
the  underwriters  during the  subscription  period,  the amount of unsubscribed
securities to be purchased by the underwriters,  and the terms of any subsequent
reoffering  thereof. If any public offering by the underwriters is to be made on
terms  differing  from  those set forth on the cover page of the  prospectus,  a
post-effective amendment will be filed to set forth the terms of such offering.

         (d)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act may be permitted to directors,  officers and controlling  persons
of the  registrant  pursuant  to the  provisions  described  in  Item 15 of this
Registration Statement or otherwise, the registrant has been advised that in the
opinion of the  Securities  and  Exchange  Commission  such  indemnification  is
against  public  policy as expressed in the  Securities  Act and is,  therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than in payment by the  registrant  of expenses  incurred or
paid  by a  trust  manager,  director,  officer  or  controlling  person  in the
successful  defense of any action,  suit or proceeding) is asserted  against the
registrant by such trust manager,  director,  officer or  controlling  person in
connection with the securities  being  registered  hereby,  the registrant will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

                    SECTION  104.  Acts of  Holders.  (1) Any  request,  demand,
               authorization, direction, notice, consent, waiver or other action
               provided by this Indenture to be given or taken by Holders of the
               Outstanding  Securities  of all series or one or more series,  as
               the case may be, may be embodied in and  evidenced by one or more
               instruments of substantially similar tenor signed by such Holders
               in person or by agents duly  appointed in writing.  If Securities
               of a series  are  issuable  as Bearer  Securities,  any  request,
               demand,  authorization,  direction,  notice,  consent,  waiver or
               other action  provided by this  Indenture to be given or taken by
               Holders of  Securities  of such  series  may,  alternatively,  be
               embodied in and  evidenced by the record of Holders of Securities
               of such series  voting in favor  thereof,  either in person or by
               proxies duly  appointed in writing,  at any meeting of Holders of
               Securities of such series duly called and held in accordance with
               the  provisions  of Article  Fifteen,  or a  combination  of such
               instruments  and any such  record.  Except  as  herein  otherwise
               expressly provided,  such action shall become effective when such
               instrument or  instruments or record or both are delivered to the
               Trustee  and,  where  it is  hereby  expressly  required,  to the
               Company.  Such instrument or instruments and any such record (and
               the action  embodied  therein and  evidenced  thereby) are herein
               sometimes  referred to as the "Act" of the Holders  signing  such
               instrument or instruments or so voting at any such meeting. Proof
               of execution of any such  instrument  or of a writing  appointing
               any such  agent,  or of the  holding by any Person of a Security,
               shall be sufficient for any purpose of this Indenture. The record
               of any  meeting of Holders of  Securities  shall be proved in the
               manner provided in Section 1506.

                    (2) The fact and date of the  execution by any Person of any
               such  instrument  or writing may be proved by the  affidavit of a
               witness of such  execution or by a certificate of a notary public
               or other  officer  authorized by law to take  acknowledgments  of
               deeds,  certifying that the individual signing such instrument or
               writing  acknowledged  to him the execution  thereof.  Where such
               execution  is by a signer  acting in a  capacity  other  than his
               individual  capacity,  such  certificate or affidavit  shall also
               constitute  sufficient proof of his authority.  The fact and date
               of the  execution  of any  such  instrument  or  writing,  or the
               authority of the Person executing the same, may also be proved in
               any other reasonable manner which the Trustee deems sufficient.

                    (3) The ownership of Registered  Securities  shall be proved
               by the Security Register.

                    (4) The ownership of Bearer  Securities may be proved by the
               production  of  such  Bearer   Securities  or  by  a  certificate
               executed,  as depositary,  by any trust company,  bank, banker or
               other depositary, wherever situated, if such certificate shall be
               deemed by the  Trustee to be  satisfactory,  showing  that at the
               date  therein  mentioned  such  Person had on  deposit  with such
               depositary,  or  exhibited to it, the Bearer  Securities  therein
               described;  or such  facts may be proved  by the  certificate  or
               affidavit of the Person holding such Bearer  Securities,  if such
               certificate   or  affidavit  is  deemed  by  the  Trustee  to  be
               satisfactory.  The  Trustee  and the Company may assume that such
               ownership  of any Bearer  Security  continues  until (1)  another
               certificate  or affidavit  bearing a later date issued in respect
               of the same  Bearer  Security  is  produced,  or (2) such  Bearer
               Security is produced to the Trustee by some other Person,  or (3)
               such Bearer  Security is surrendered in exchange for a Registered
               Security,  or (4) such Bearer Security is no longer  Outstanding.
               The  ownership  of  Bearer  Securities  may also be proved in any
               other manner which the Trustee deems sufficient.

                    (5) If  the  Company  shall  solicit  from  the  Holders  of
               Registered   Securities  any  request,   demand,   authorization,
               direction, notice, consent, waiver or other Act, the Company may,
               at its  option,  in or  pursuant  to a Board  Resolution,  fix in
               advance a record date for the  determination  of Holders entitled
               to give such request, demand,  authorization,  direction, notice,
               consent,  waiver or other  Act,  but the  Company  shall  have no
               obligation to do so.  Notwithstanding  TIA Section  316(c),  such
               record date shall be the record date  specified in or pursuant to
               such Board Resolution, which shall be a date not earlier than the
               date 30 days prior to the first solicitation of Holders generally
               in  connection  therewith  and  not  later  than  the  date  such
               solicitation is completed.  If such a record date is fixed,  such
               request,  demand,  authorization,   direction,  notice,  consent,
               waiver or other  Act may be given  before  or after  such  record
               date,  but only the Holders of record at the close of business on
               such record  date shall be deemed to be Holders for the  purposes
               of  determining  whether  Holders of the requisite  proportion of
               Outstanding  Securities have authorized or agreed or consented to
               such request, demand, authorization,  direction, notice, consent,
               waiver  or  other  Act,  and for  that  purpose  the  Outstanding
               Securities  shall be computed as of such  record  date;  provided
               that no such  authorization,  agreement or consent by the Holders
               on such  record  date shall be deemed  effective  unless it shall
               become effective pursuant to the provisions of this Indenture not
               later than eleven months after the record date.

     In the absence of any such record date fixed by the Company,  regardless as
to whether a  solicitation  of the Holders is occurring on behalf of the Company
or any Holder,  the Trustee may, at its option, fix in advance a record date for
the  determination  of such  Holders  entitled  to give  such  request,  demand,
authorization,  direction, notice, consent, waiver or other Act, but the Trustee
shall have no obligation to do so. Any such record date shall be a date not more
than 30 days prior to the first  solicitation of Holders generally in connection
therewith no later than the date of such solicitation.

                    (6) Any request, demand,  authorization,  direction, notice,
               consent,  waiver or other Act of the Holder of any Security shall
               bind every future  Holder of the same  Security and the Holder of
               every Security issued upon the  registration of transfer  thereof
               or in exchange therefor or in lieu thereof in respect of anything
               done, omitted or suffered to be done by the Trustee, any Security
               Registrar,  any Paying  Agent,  any  Authenticating  Agent or the
               Company in  reliance  thereon,  whether or not  notation  of such
               action is made upon such Security.

                    SECTION 105.  Notices,  etc.,  to Trustee and  Company.  Any
               request,  demand,  authorization,   direction,  notice,  consent,
               waiver or Act of Holders or other document  provided or permitted
               by this  Indenture  to be made upon,  given or  furnished  to, or
               filed with,

                    (1) the  Trustee  by any Holder or by the  Company  shall be
               sufficient for every purpose hereunder if made, given,  furnished
               or  filed  in  writing  to or with  the  Trustee  at 600  Travis,
               Houston, Texas 77002; or

                    (2) the  Company by the  Trustee  or by any Holder  shall be
               sufficient for every purpose  hereunder  (unless otherwise herein
               expressly provided) if in writing and mailed, first class postage
               prepaid,  to the  Company  addressed  to it at the address of its
               principal  office  specified  in  the  first  paragraph  of  this
               Indenture or at any other address previously furnished in writing
               to the Trustee by the Company.

                    SECTION 106. Notice to Holders; Waiver. Where this Indenture
               provides  for  notice  of any  event  to  Holders  of  Registered
               Securities  by the Company or the  Trustee,  such notice shall be
               sufficiently  given (unless otherwise herein expressly  provided)
               if in writing and mailed,  first-class  postage prepaid,  to each
               such Holder  affected by such event, at his address as it appears
               in the Security Register, not later than the latest date, and not
               earlier than the earliest date, prescribed for the giving of such
               notice.  In any  case  where  notice  to  Holders  of  Registered
               Securities  is given by mail,  neither  the  failure to mail such
               notice, nor any defect in any notice so mailed, to any particular
               Holder shall affect the  sufficiency  of such notice with respect
               to other Holders of Registered  Securities or the  sufficiency of
               any  notice to  Holders of Bearer  Securities  given as  provided
               herein.  Any  notice  mailed  to a Holder  in the  manner  herein
               prescribed shall be conclusively  deemed to have been received by
               such Holder,  whether or not such Holder  actually  receives such
               notice.

     If by reason of the suspension of or irregularities in regular mail service
or by reason of any other cause it shall be impracticable to give such notice by
mail,  then such  notification  to Holders of Registered  Securities as shall be
made with the approval of the Trustee shall constitute a sufficient notification
to such Holders for every purpose hereunder.

     Except as otherwise  expressly provided herein or otherwise  specified with
respect to any Securities pursuant to Section 301, where this Indenture provides
for notice to Holders of Bearer  Securities  of any event,  such notice shall be
sufficiently given if published in an Authorized  Newspaper in New York City and
in such  other  city or  cities  as may be  specified  in such  Securities  on a
Business Day,  such  publication  to be not later than the latest date,  and not
earlier than the earliest date,  prescribed  for the giving of such notice.  Any
such notice  shall be deemed to have been given on the date of such  publication
or, if published more than once, on the date of the first such publication.

     If by reason of the suspension of  publication of any Authorized  Newspaper
or  Authorized  Newspapers  or  by  reason  of  any  other  cause  it  shall  be
impracticable to publish any notice to Holders of Bearer  Securities as provided
above,  then such notification to Holders of Bearer Securities as shall be given
with the  approval of the Trustee  shall  constitute  sufficient  notice to such
Holders  for every  purpose  hereunder.  Neither  the  failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so  published,  shall  affect the  sufficiency  of such
notice with respect to other Holders of Bearer  Securities or the sufficiency of
any notice to Holders of Registered Securities given as provided herein.

     Any request, demand,  authorization,  direction,  notice, consent or waiver
required or permitted  under this  Indenture  shall be in the English  language,
except that any published  notice may be in an official  language of the country
of publication.

     Where this Indenture provides for notice in any manner,  such notice may be
waived in writing by the Person  entitled to receive such notice,  either before
or after the event,  and such waiver  shall be the  equivalent  of such  notice.
Waivers of notice by Holders  shall be filed with the  Trustee,  but such filing
shall not be a  condition  precedent  to the  validity  of any  action  taken in
reliance upon such waiver.

                    SECTION 107.  Effect of Headings and Table of Contents.  The
               Article and Section headings herein and the Table of Contents are
               for  convenience  only and  shall  not  affect  the  construction
               hereof.

                    SECTION 108.  Successors  and  Assigns.  All  covenants  and
               agreements  in this  Indenture  by the  Company  shall  bind  its
               successors and assigns, whether so expressed or not.

                    SECTION 109.  Severability  Clause. In case any provision in
               this  Indenture  or in any  Security or coupon  shall be invalid,
               illegal   or   unenforceable,    the   validity,   legality   and
               enforceability  of the remaining  provisions shall not in any way
               be affected or impaired thereby.

                    SECTION  110.   Benefits  of  Indenture.   Nothing  in  this
               Indenture or in the  Securities  or coupons,  express or implied,
               shall give to any  Person,  other than the  parties  hereto,  any
               Security  Registrar,  any Paying Agent, any Authenticating  Agent
               and their successors hereunder and the Holders any benefit or any
               legal or equitable right, remedy or claim under this Indenture.

                    SECTION  111.   Governing   Law.  This   Indenture  and  the
               Securities  and coupons  shall be governed  by and  construed  in
               accordance  with the law of the State of New York. This Indenture
               is subject to the  provisions  of the TIA that are required to be
               part of this Indenture and shall,  to the extent  applicable,  be
               governed by such provisions.

                    SECTION 112. Legal Holidays.  In any case where any Interest
               Payment  Date,  Redemption  Date,  Repayment  Date,  sinking fund
               payment date,  Stated  Maturity or Maturity of any Security shall
               not  be  a   Business   Day  at  any  Place  of   Payment,   then
               (notwithstanding  any other  provision  of this  Indenture or any
               Security or coupon  other than a provision in the  Securities  of
               any series which  specifically  states that such provision  shall
               apply in lieu  hereof),  payment of  interest  or any  Additional
               Amounts or principal  (and  premium,  if any) need not be made at
               such Place of  Payment on such date,  but may be made on the next
               succeeding  Business  Day at such Place of Payment  with the same
               force  and  effect  as if  made  on the  Interest  Payment  Date,
               Redemption Date,  Repayment Date or sinking fund payment date, or
               at the Stated  Maturity or  Maturity,  provided  that no interest
               shall  accrue on the  amount so payable  for the period  from and
               after such Interest  Payment  Date,  Redemption  Date,  Repayment
               Date, sinking fund payment date, Stated Maturity or Maturity,  as
               the case may be.

                    SECTION  113.  Immunity  of  Shareholders,  Trust  Managers,
               Officers and Agents of the Company. In accordance with Article 15
               of the Amended and Restated  Declaration  of Trust of the Company
               ("Declaration of Trust"),  the Trustee recognizes and agrees that
               the  obligations  of the  Company  under  the  Indenture  and the
               Securities and all documents delivered in the name of the Company
               in  connection  herewith  and  therewith  do not  and  shall  not
               constitute personal obligations of the Trust Managers,  officers,
               employees,  agents or shareholders of the Company or any of them,
               and shall not involve any claim against or personal  liability on
               the part of any of  them,  and that  all  persons  including  the
               Trustee  shall look  solely to the assets of the  Company for the
               payment of any claim  thereunder or for the  performance  thereof
               and  shall  not  seek  recourse   against  such  Trust  Managers,
               officers, employees, agents or shareholders of the Company or any
               of them or any of their  personal  assets for such  satisfaction.
               The  performance  of the  obligations  of the  Company  under the
               Indenture and the Securities  and all documents  delivered in the
               name of the Company in connection therewith shall not be deemed a
               waiver of any rights or powers of the Company,  Trust Managers or
               shareholders under the Declaration of Trust.

                                   ARTICLE TWO

                                SECURITIES FORMS

                    SECTION 201. Forms of Securities. The Registered Securities,
               if any, of each series and the Bearer Securities, if any, of each
               series and related coupons shall be in substantially the forms as
               shall  be  established  in one or  more  indentures  supplemental
               hereto or  approved  from time to time by or  pursuant to a Board
               Resolution  in  accordance  with  Section  301,  shall  have such
               appropriate  insertions,   omissions,   substitutions  and  other
               variations as are required or permitted by this  Indenture or any
               indenture supplemental hereto, and may have such letters, numbers
               or other marks of  identification or designation and such legends
               or   endorsements   placed   thereon  as  the  Company  may  deem
               appropriate  and as are not  inconsistent  with the provisions of
               this  Indenture,  or as may be required to comply with any law or
               with any rule or  regulation  made  pursuant  thereto or with any
               rule or regulation of any stock  exchange on which the Securities
               may be listed, or to conform to usage.

     Unless   otherwise   specified  as  contemplated  by  Section  301,  Bearer
Securities shall have interest coupons attached.

     The  definitive  Securities and coupons shall be printed,  lithographed  or
engraved or produced by any  combination  of these  methods on a steel  engraved
border or steel engraved borders or may be produced in any other manner,  all as
determined by the officers executing such Securities or coupons, as evidenced by
their execution of such Securities or coupons.

                    SECTION   202.    Form   of   Trustee's    Certificate    of
               Authentication. Subject to Section 611, the Trustee's certificate
               of authentication shall be in substantially the following form:

     This is one of the Securities of the series designated  therein referred to
in the within-mentioned Indenture.


                         By:      __________________________________, as Trustee
                                            Authorized Signatory

                    SECTION  203.   Securities   Issuable  in  Global  Form.  If
               Securities  of or within a series are issuable in global form, as
               specified as contemplated  by Section 301, then,  notwithstanding
               clause (8) of Section 301 and the  provisions of Section 302, any
               such Security shall represent such of the Outstanding  Securities
               of such series as shall be specified therein and may provide that
               it shall represent the aggregate amount of Outstanding Securities
               of such  series from time to time  endorsed  thereon and that the
               aggregate  amount  of  Outstanding   Securities  of  such  series
               represented  thereby  may  from  time  to time  be  increased  or
               decreased to reflect exchanges.  Any endorsement of a Security in
               global form to reflect the amount, or any increase or decrease in
               the amount, of Outstanding  Securities  represented thereby shall
               be made by the Trustee in such manner and upon instructions given
               by such Person or Persons as shall be specified therein or in the
               Company Order to be delivered to the Trustee  pursuant to Section
               303 or 304.  Subject to the  provisions  of Section  303 and,  if
               applicable,  Section 304, the Trustee shall deliver and redeliver
               any  Security  in  permanent  global  form in the manner and upon
               instructions  given by the Person or Persons specified therein or
               in the applicable  Company Order.  If a Company Order pursuant to
               Section 303 or 304 has been, or simultaneously is, delivered, any
               instructions  by the  Company  with  respect  to  endorsement  or
               delivery or  redelivery  of a Security in global form shall be in
               writing  but need not  comply  with  Section  102 and need not be
               accompanied by an Opinion of Counsel.

     The  provisions  of the last  sentence  of Section  303 shall  apply to any
Security  represented  by a Security in global form if such  Security  was never
issued and sold by the  Company  and the  Company  delivers  to the  Trustee the
Security in global  form  together  with  written  instructions  (which need not
comply with  Section 102 and need not be  accompanied  by an Opinion of Counsel)
with regard to the reduction in the principal  amount of Securities  represented
thereby,  together with the written statement  contemplated by the last sentence
of Section 303.

     Notwithstanding  the provisions of Section 307, unless otherwise  specified
as  contemplated  by Section  301,  payment of  principal of and any premium and
interest on any Security in permanent global form shall be made to the Person or
Persons specified therein.

     Notwithstanding the provisions of Section 308 and except as provided in the
preceding  paragraph,  the Company, the Trustee and any agent of the Company and
the Trustee shall treat as the Holder of such  principal  amount of  Outstanding
Securities  represented  by a  permanent  global  Security  (i) in the case of a
permanent  global  Security in  registered  form,  the Holder of such  permanent
global  Security in registered  form, or (ii) in the case of a permanent  global
Security in bearer form, Euroclear or CEDEL.

               (12) whether the amount of payments of principal of (and premium,
          if any) or interest,  if any, on the  Securities  of the series may be

          or stated to be payable,  the period or periods within which,  and the
          terms and  conditions  upon which,  such election may be made, and the
          time and manner  of,  and  identity  of the  exchange  rate agent with
          responsibility for, determining the exchange rate between the currency

          be specified;

               (15) any  deletions  from,  modifications  of or additions to the
          Events  of  Default  or  covenants  of the  Company  with  respect  to

          global  form  and  whether  any  Securities  of the  series  are to be

          whether  beneficial  owners of interests in any such permanent  global
          Security may exchange such interests for Securities of such series and

          severally mature, and the extent to which, or the manner in which, any
          interest payable on a temporary global Security on an Interest Payment

               (19) the  applicability,  if any, of Sections 1402 and/or 1403 to
          the Securities of the series and any provisions in modification of, in
          addition to or in lieu of any of the provisions of Article Fourteen;

               (20) if the  Securities  of such  series  are to be  issuable  in
          definitive  form (whether  upon  original  issue or upon exchange of a
          temporary  Security  of such  series)  only upon  receipt  of  certain
          certificates or other  documents or satisfaction of other  conditions,
          then  the  form  and/or  terms  of  such  certificates,  documents  or
          conditions;

          of  the  series  to any  Holder  who is  not a  United  States  person
          (including any modification to the definition of such term) in respect
          of any tax,  assessment or governmental charge and, if so, whether the
          Company will have the option to redeem such Securities rather than pay
          such Additional Amounts (and the terms of any such option);

               (22)  the  obligation,  if any,  of the  Company  to  permit  the
          conversion of the Securities of such series into the Company's  Common
          Shares  or  Preferred  Shares,  as the case may be,  and the terms and
          conditions  upon which such conversion  shall be effected  (including,
          without  limitation,   the  initial  conversion  price  or  rate,  the

          purposes of conversion); and

               (23) any other  terms of the  series  (which  terms  shall not be
          inconsistent with the provisions of this Indenture).

     All Securities of any one series and the coupons appertaining to any Bearer
Securities of such series shall be substantially  identical  except, in the case
of  Registered  Securities,  as to  denomination  and except as may otherwise be
provided in or pursuant to such Board  Resolution  (subject to Section  303) and
set forth in such Officers'  Certificate  or in any such indenture  supplemental
hereto.  All  Securities  of any one series  need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

     If any of the terms of the  Securities  of any  series are  established  by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such  action(s)  shall be certified  by the  Secretary or an Assistant
Secretary  of the  Company  and  delivered  to the  Trustee  at or  prior to the
delivery of the Officers'  Certificate setting forth the terms of the Securities
of such series.

               SECTION 302.  Denominations.  The Securities of each series shall
          be  issuable  in  such   denominations   as  shall  be   specified  as
          contemplated  by Section 301. With respect to Securities of any series
          denominated  in Dollars,  in the absence of any such  provisions  with
          respect to the Securities of any series, the Registered  Securities of
          such series,  other than Registered  Securities  issued in global form
          (which may be of any denomination), shall be issuable in denominations
          of $1,000 and any integral  multiple thereof and the Bearer Securities
          of such  series,  other than Bearer  Securities  issued in global form
          (which may be of any denomination), shall be issuable in denominations
          of $5,000, and in any integral multiple thereof.

               SECTION 303. Execution, Authentication,  Delivery and Dating. The
          Securities and any coupons  appertaining  thereto shall be executed on
          behalf of the Company by a Trust Manager and its  Chairman,  its Chief
          Executive  Officer,  its  President,  its Treasurer or one of its Vice
          Presidents  and  attested  by its  Secretary  or one of its  Assistant
          Secretaries.  The  signature  of  any  of  these  individuals  on  the
          Securities  and coupons may be manual or facsimile  signatures  of the
          present or any future such  authorized  officer and trustee and may be
          imprinted or otherwise reproduced on the Securities.

     Securities  or  coupons  bearing  the  manual or  facsimile  signatures  of
individuals  who were at any time the proper  officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the Company may deliver Securities of any series,  together with any
coupon  appertaining  thereto,  executed  by  the  Company  to the  Trustee  for
authentication,  together  with a  Company  Order  for  the  authentication  and
delivery  of such  Securities,  and the Trustee in  accordance  with the Company
Order shall authenticate and deliver such Securities;  provided,  however, that,
unless otherwise  specified with respect to any series of Securities pursuant to
Section 301, a Bearer  Security may be delivered in connection with its original
issuance only if the Person  entitled to receive such Bearer Security shall have
furnished a certificate  to Euroclear or CEDEL,  as the case may be, in the form
set forth in Exhibit A-1 to this  Indenture or such other  certificate as may be
specified  with  respect to any series of  Securities  pursuant to Section  301,
dated no  earlier  than 15 days  prior to the  earlier of the date on which such
Bearer Security is delivered and the date on which any temporary  Security first
becomes  exchangeable  for such Bearer  Security in accordance with the terms of
such temporary Security and this Indenture. If any Security shall be represented
by a permanent  global Bearer  Security,  then, for purposes of this Section and
Section 304, the notation of a beneficial owner's interest therein upon original
issuance of such  Security or upon  exchange of a portion of a temporary  global
Security shall be deemed to be delivery in connection with its original issuance
of such beneficial owner's interest in such permanent global Security. Except as
permitted  by Section  306,  the Trustee or the  Authenticating  Agent shall not
authenticate and deliver any Bearer Security unless all appurtenant  coupons for
interest then matured have been detached and cancelled.

     If all of the Securities of any series are not to be issued at one time and
if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee
for the issuance of such  Securities  and  determining  the terms of  particular
Securities of such series, such as interest rate or formula, maturity date, date
of issuance and date from which interest shall accrue.  In  authenticating  such
Securities,  and accepting the additional  responsibilities under this Indenture
in relation to such  Securities,  the Trustee shall be entitled to receive,  and
(subject to TIA Sections  315(a)  through  315(d))  shall be fully  protected in
relying upon:

                  (1)      an Opinion of Counsel stating that:

                                    (a) the form or forms of such Securities and
                           any coupons have been  established in conformity with
                           the provisions of this Indenture;

                                    (b) the  terms  of such  Securities  and any
                           coupons have been  established in conformity with the
                           provisions of this Indenture; and

                                    (c)  such  Securities,   together  with  any
                           coupons  appertaining   thereto,  when  completed  by
                           appropriate  insertions and executed and delivered by
                           the  Company to the  Trustee  for  authentication  in
                           accordance  with this  Indenture,  authenticated  and
                           delivered  by the  Trustee  in  accordance  with this
                           Indenture and issued by the Company in the manner and
                           subject to any  conditions  specified in such Opinion
                           of Counsel,  will constitute legal, valid and binding
                           obligations of the Company, enforceable in accordance
                           with their terms,  subject to applicable  bankruptcy,
                           insolvency,  reorganization and other similar laws of
                           general  applicability  relating to or affecting  the
                           enforcement  of  creditors'  rights  generally and to
                           general equitable principles; and

               (2)  an  Officers'   Certificate   stating  that  all  conditions
          precedent  provided for in this Indenture  relating to the issuance of
          the  Securities  have been  complied with and that, to the best of the
          knowledge of the signers of such certificate, no Event of Default with
          respect  to  any  of  the  Securities   shall  have  occurred  and  be
          continuing.

If such  form or terms  have  been so  established,  the  Trustee  shall  not be
required  to  authenticate  such  Securities  if the  issue  of such  Securities
pursuant  to this  Indenture  will  affect the  Trustee's  own  rights,  duties,
obligations  or immunities  under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

     Notwithstanding  the  provisions  of  Section  301  and  of  the  preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant  to  Section  301 or a Company  Order,  or an  Opinion of Counsel or an
Officers'  Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each  Security of such series,  but such order,  opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be  delivered  at or before the time of issuance of the first  Security of
such series.

     Each Registered  Security shall be dated the date of its authentication and
each Bearer  Security shall be dated as of the date specified as contemplated by
Section 301.

     No Security or coupon shall be entitled to any benefit under this Indenture
or be valid or obligatory  for any purpose unless there appears on such Security
or Security to which such coupon  appertains  a  certificate  of  authentication
substantially  in the form  provided for herein duly  executed by the Trustee by
manual  signature of an  authorized  signatory,  and such  certificate  upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly  authenticated  and  delivered  hereunder  and is  entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company,  and the  Company  shall  deliver  such  Security  to the  Trustee  for
cancellation as provided in Section 309 together with a written statement (which
need not comply with  Section 102 and need not be  accompanied  by an Opinion of
Counsel)  stating  that such  Security  has never  been  issued  and sold by the
Company,  for all purposes of this Indenture such Security shall be deemed never
to have been  authenticated and delivered  hereunder and shall never be entitled
to the benefits of this Indenture.

               SECTION 304. Temporary Securities. (a) Pending the preparation of
          definitive Securities of any series, the Company may execute, and upon
          Company Order the Trustee shall  authenticate  and deliver,  temporary
          Securities which are printed, lithographed,  typewritten, mimeographed
          or otherwise produced, in any authorized  denomination,  substantially
          of the tenor of the  definitive  Securities  in lieu of which they are
          issued, in registered form, or, if authorized, in bearer form with one
          or  more  coupons  or  without  coupons,  and  with  such  appropriate
          insertions,  omissions,  substitutions  and  other  variations  as the
          officers  executing such  Securities may  determine,  as  conclusively
          evidenced  by  their  execution  of such  Securities.  In the  case of
          Securities of any series,  such temporary  Securities may be in global
          form.

     Except in the case of temporary  Securities  in global form (which shall be
exchanged  in  accordance  with Section  304(b) or as  otherwise  provided in or
pursuant  to a Board  Resolution),  if  temporary  Securities  of any series are
issued,  the  Company  will cause  definitive  Securities  of that  series to be
prepared  without  unreasonable  delay.  After  the  preparation  of  definitive
Securities  of such series,  the  temporary  Securities  of such series shall be
exchangeable  for  definitive  Securities  of such series upon  surrender of the
temporary  Securities of such series at the office or agency of the Company in a
Place of Payment for that series,  without charge to the Holder.  Upon surrender
for  cancellation  of any  one  or  more  temporary  Securities  of  any  series
(accompanied by any non-matured coupons appertaining thereto), the Company shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
like principal amount of definitive  Securities of the same series of authorized
denominations;  provided,  however,  that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security; and provided further,
that a definitive Bearer Security shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 303.
Until so exchanged, the temporary Securities of any series shall in all respects
be entitled to the same benefits under this  Indenture as definitive  Securities
of such series.

     (b) Unless otherwise  provided in or pursuant to a Board  Resolution,  this
Section  304(b)  shall govern the  exchange of  temporary  Securities  issued in
global form other than through the  facilities of The  Depository  Trust Company
("DTC").  If any such  temporary  Security is issued in global  form,  then such
temporary global Security shall, unless otherwise provided therein, be delivered
to  the  London  office  of a  depositary  or  common  depositary  (the  "Common
Depositary"),  for the  benefit  of  Euroclear  and  CEDEL,  for  credit  to the
respective  accounts of the  beneficial  owners of such  Securities  (or to such
other accounts as they may direct).

     Without  unnecessary  delay  but in any  event  not  later  than  the  date
specified in, or determined  pursuant to the terms of, any such temporary global
Security  (the  "Exchange  Date"),  the  Company  shall  deliver to the  Trustee
definitive  Securities,  in aggregate  principal  amount equal to the  principal
amount of such temporary global Security,  executed by the Company.  On or after
the Exchange Date,  such temporary  global  Security shall be surrendered by the
Common Depositary to the Trustee,  or its agent, as the Company's agent for such
purpose,  to be  exchanged,  in  whole  or,  from  time to time,  in  part,  for
definitive  Securities  without charge,  and the Trustee shall  authenticate and
deliver,  in exchange for each portion of such  temporary  global  Security,  an
equal aggregate principal amount of definitive  Securities of the same series of
authorized  denominations  and of like tenor as the  portion  of such  temporary
global  Security to be exchanged.  The definitive  Securities to be delivered in
exchange  for any  such  temporary  global  Security  shall be in  bearer  form,
registered form,  permanent  global bearer form or permanent  global  registered
form, or any combination  thereof,  as specified as contemplated by Section 301,
and, if any combination thereof is so specified,  as requested by the beneficial
owner thereof;  provided,  however,  that,  unless  otherwise  specified in such
temporary global Security, upon such presentation by the Common Depositary, such
temporary  global  Security is accompanied  by a certificate  dated the Exchange
Date or a  subsequent  date and signed by  Euroclear  as to the  portion of such
temporary  global  Security  held for its  account  then to be  exchanged  and a
certificate  dated the Exchange Date or a subsequent date and signed by CEDEL as
to the portion of such temporary global Security held for its account then to be
exchanged,  each in the form set forth in Exhibit  A-2 to this  Indenture  or in
such other form as may be  established  pursuant to Section  301;  and  provided
further, that, definitive Bearer Securities shall be delivered in exchange for a
portion of a temporary  global Security only in compliance with the requirements
of Section 303.

     Unless otherwise specified in such temporary global Security,  the interest
of a beneficial  owner of Securities of a series in a temporary  global Security
shall be  exchanged  for  definitive  Securities  of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL,  as the case may be, to request such  exchange on his behalf and delivers
to Euroclear or CEDEL,  as the case may be, a certificate  in the form set forth
in Exhibit A-1 to this  Indenture  (or in such other form as may be  established
pursuant to Section  301),  dated no earlier  than 15 days prior to the Exchange
Date,  copies  of which  certificate  shall be  available  from the  offices  of
Euroclear and CEDEL, the Trustee,  any  Authenticating  Agent appointed for such
series of Securities and each Paying Agent.  Unless otherwise  specified in such
temporary global Security, any such exchange shall be made free of charge to the
beneficial  owners  of such  temporary  global  Security,  except  that a Person
receiving  definitive  Securities  must  bear  the cost of  insurance,  postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary global
Security shall be delivered only outside the United States.

     Until exchanged in full as hereinabove  provided,  the temporary Securities
of any series shall in all respects be entitled to the same benefits  under this
Indenture  as  definitive  Securities  of the  same  series  and of  like  tenor
authenticated and delivered  hereunder,  except that, unless otherwise specified
as contemplated by Section 301,  interest payable on a temporary global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable  Exchange  Date  shall be  payable  to  Euroclear  and  CEDEL on such
Interest  Payment Date upon  delivery by Euroclear and CEDEL to the Trustee of a
certificate  or  certificates  in the form  set  forth  in  Exhibit  A-2 to this
Indenture  (or in such other  forms as may be  established  pursuant  to Section
301), for credit without further interest on or after such Interest Payment Date
to the  respective  accounts  of Persons who are the  beneficial  owners of such
temporary  global  Security  on such  Interest  Payment  Date and who have  each
delivered  to  Euroclear or CEDEL,  as the case may be, a  certificate  dated no
earlier than 15 days prior to the Interest  Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such
other  forms as may be  established  pursuant to Section  301).  Notwithstanding
anything to the contrary herein contained,  the certifications  made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section  304(b) and of the third  paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary global Security with respect to which such  certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of  certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial  interest in a temporary  global  Security  will be
made unless and until such interest in such temporary global Security shall have
been  exchanged  for an  interest  in a  definitive  Security.  Any  interest so
received  by  Euroclear  and  CEDEL  and not paid as  herein  provided  shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

               SECTION 305. Registration, Registration of Transfer and Exchange.
          The Company  shall cause to be kept at the  Corporate  Trust Office of
          the  Trustee or in any  office or agency of the  Company in a Place of
          Payment a  register  for each  series  of  Securities  (the  registers
          maintained  in such  office  or in any such  office  or  agency of the
          Company in a Place of  Payment  being  herein  sometimes  referred  to
          collectively  as the "Security  Register")  in which,  subject to such
          reasonable regulations as it may prescribe,  the Company shall provide
          for the  registration  of  Registered  Securities  and of transfers of
          Registered Securities.  The Security Register shall be in written form
          or any other form capable of being  converted into written form within
          a reasonable  time.  The Trustee,  at its Corporate  Trust Office,  is
          hereby appointed  "Security  Registrar" for the purpose of registering
          Registered  Securities and transfers of Registered  Securities on such
          Security  Register as herein  provided.  In the event that the Trustee
          shall  cease to be  Security  Registrar,  it shall  have the  right to
          examine the Security Register at all reasonable times.

     Subject  to  the  provisions  of  this  Section  305,  upon  surrender  for
registration of transfer of any Registered  Security of any series at any office
or agency of the  Company in a Place of Payment  for that  series,  the  Company
shall execute,  and the Trustee shall  authenticate and deliver,  in the name of
the designated transferee or transferees,  one or more new Registered Securities
of the same series,  of any  authorized  denominations  and of a like  aggregate
principal  amount,  bearing  a number  not  contemporaneously  outstanding,  and
containing identical terms and provisions.

     Subject to the provisions of this Section 305, at the option of the Holder,
Registered  Securities  of any  series  may be  exchanged  for other  Registered
Securities of the same series,  of any authorized  denomination or denominations
and of a  like  aggregate  principal  amount,  containing  identical  terms  and
provisions,  upon surrender of the Registered  Securities to be exchanged at any
such  office  or  agency.   Whenever  any  such  Registered  Securities  are  so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Registered  Securities which the Holder making the
exchange is entitled to receive.  Unless otherwise specified with respect to any
series of Securities as contemplated  by Section 301, Bearer  Securities may not
be issued in exchange for Registered Securities.

     If (but only if) permitted by the applicable  Board Resolution and (subject
to Section 303) set forth in the  applicable  Officers'  Certificate,  or in any
indenture supplemental hereto,  delivered as contemplated by Section 301, at the
option of the  Holder,  Bearer  Securities  of any series may be  exchanged  for
Registered Securities of the same series of any authorized  denominations and of
a like  aggregate  principal  amount and  tenor,  upon  surrender  of the Bearer
Securities  to be  exchanged  at any such office or agency,  with all  unmatured
coupons and all matured coupons in default thereto  appertaining.  If the Holder
of a Bearer  Security is unable to produce any such unmatured  coupon or coupons
or matured  coupon or coupons in default,  any such  permitted  exchange  may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such  missing  coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may  require,  in their  sole  discretion,  to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to any Paying Agent any such  missing  coupon in respect of which such a payment
shall have been made,  such  Holder  shall be  entitled to receive the amount of
such payment;  provided,  however, that, except as otherwise provided in Section
1002,  interest  represented by coupons shall be payable only upon  presentation
and surrender of those coupons at an office or agency located outside the United
States.  Notwithstanding the foregoing,  in case a Bearer Security of any series
is  surrendered  at any such  office  or agency in a  permitted  exchange  for a
Registered  Security  of the same  series  and like  tenor  after  the  close of
business at such office or agency on (i) any Regular  Record Date and before the
opening of business at such office or agency on the  relevant  Interest  Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer  Security shall be surrendered  without the coupon  relating to such
Interest  Payment  Date or proposed  date for  payment,  as the case may be, and
interest or Defaulted Interest,  as the case may be, will not be payable on such
Interest  Payment  Date or  proposed  date for  payment,  as the case may be, in
respect of the Registered  Security issued in exchange for such Bearer Security,
but will be payable  only to the Holder of such  coupon  when due in  accordance
with  the  provisions  of  this  Indenture.   Whenever  any  Securities  are  so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

     Notwithstanding   the   foregoing,   except  as   otherwise   specified  as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph.  If the depositary for any permanent  global
Security is DTC, then, unless the terms of such global Security expressly permit
such  global  Security  to be  exchanged  in  whole  or in part  for  definitive
Securities,  a global  Security may be transferred,  in whole,  but not in part,
only to a nominee of DTC, or by a nominee of DTC to DTC,  or to a  successor  to
DTC for such global Security selected or approved by the Company or to a nominee
of such  successor  to DTC. If at any time DTC  notifies  the Company that it is
unwilling or unable to continue as depositary for the applicable global Security
or  Securities or if at any time DTC ceases to be a clearing  agency  registered
under the  Securities  Exchange Act of 1934 if so required by applicable  law or
regulation,  the Company  shall appoint a successor  depositary  with respect to
such global  Security or  Securities.  If (x) a  successor  depositary  for such
global  Security or Securities  is not  appointed by the Company  within 90 days
after the Company  receives such notice or becomes aware of such  unwillingness,
inability  or  ineligibility,  (y) an  Event  of  Default  has  occurred  and is
continuing and the beneficial owners representing a majority in principal amount
of the applicable  series of Securities  represented by such global  Security or
Securities  advise DTC to cease acting as depositary for such global Security or
Securities or (z) the Company,  in its sole  discretion,  determines at any time
that all Outstanding  Securities (but not less than all) of any series issued or
issuable  in the  form of one or more  global  Securities  shall  no  longer  be
represented  by such global  Security  or  Securities,  then the  Company  shall
execute, and the Trustee shall authenticate and deliver definitive Securities of
like series,  rank, tenor and terms in definitive form in an aggregate principal
amount equal to the principal  amount of such global Security or Securities.  If
any beneficial  owner of an interest in a permanent global Security is otherwise
entitled to exchange  such  interest for  Securities  of such series and of like
tenor and  principal  amount of another  authorized  form and  denomination,  as
specified as contemplated by Section 301 and provided that any applicable notice
provided in the permanent  global  Security shall have been given,  then without
unnecessary  delay but in any event not later  than the  earliest  date on which
such interest may be so exchanged,  the Company shall  execute,  and the Trustee
shall  authenticate  and deliver  definitive  Securities in aggregate  principal
amount equal to the principal amount of such beneficial owner's interest in such
permanent global Security. On or after the earliest date on which such interests
may be so exchanged,  such permanent  global  Security shall be surrendered  for
exchange by DTC or such other  depositary  as shall be  specified in the Company
Order with  respect  thereto to the  Trustee,  as the  Company's  agent for such
purpose;  provided,  however,  that no such  exchanges may occur during a period
beginning at the opening of business 15 days before any  selection of Securities
to be redeemed and ending on the relevant  Redemption  Date, if the Security for
which  exchange is requested may be among those  selected for  redemption.  If a
Registered  Security is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the  relevant  Interest  Payment  Date,  or (ii) any Special
Record  Date and the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, Interest or Defaulted Interest,
as the case  may be,  will  not be  payable  on such  Interest  Payment  Date or
proposed  date for  payment,  as the case may be, in respect of such  Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment,  as the case may be, only to the Person to whom  interest in respect of
such portion of such permanent global Security is payable in accordance with the
provisions of this Indenture.

     All  Securities  issued  upon any  registration  of transfer or exchange of
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt, and entitled to the same benefits under this Indenture,  as the Securities
surrendered upon such registration of transfer or exchange.

     Every  Registered  Security  presented or surrendered  for  registration of
transfer or for exchange or  redemption  shall (if so required by the Company or
the  Security  Registrar)  be duly  endorsed,  or be  accompanied  by a  written
instrument  of transfer  in form  satisfactory  to the Company and the  Security
Registrar,  duly executed by the Holder thereof or his attorney duly  authorized
in writing.

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange of Securities,  but the Company may require payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
with any  registration  of  transfer  or  exchange  of  Securities,  other  than
exchanges  pursuant  to  Sections  304,  906,  1107 or 1305  not  involving  any
transfer.

     The Company or the  Trustee,  as  applicable,  shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption  during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such  Securities are issuable
only as Registered Securities,  the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the  first  publication  of the  relevant  notice of  redemption  or, if such
Securities  are  also  issuable  as  Registered   Securities  and  there  is  no
publication,  the  mailing  of the  relevant  notice of  redemption,  or (ii) to
register  the transfer of or exchange  any  Registered  Security so selected for
redemption in whole or in part,  except, in the case of any Registered  Security
to be redeemed  in part,  the portion  thereof not to be  redeemed,  or (iii) to
exchange  any Bearer  Security so  selected  for  redemption  except that such a
Bearer  Security may be exchanged  for a Registered  Security of that series and
like tenor,  provided  that such  Registered  Security  shall be  simultaneously
surrendered  for  redemption,  or (iv) to issue,  register  the  transfer  of or
exchange any Security which has been  surrendered for repayment at the option of
the Holder,  except the portion,  if any, of such  Security not to be so repaid.
SECTION 306. Mutilated,  Destroyed, Lost and Stolen Securities. If any mutilated
Security or a Security with a mutilated coupon appertaining to it is surrendered
to the Trustee or the Company,  together with, in proper cases, such security or
indemnity  as may be required by the Company or the Trustee to save each of them
or any agent of either of them  harmless,  the  Company  shall  execute  and the
Trustee shall  authenticate  and deliver in exchange  therefor a new Security of
the same series and principal amount,  containing identical terms and provisions
and  bearing  a  number  not   contemporaneously   outstanding,   with   coupons
corresponding to the coupons, if any, appertaining to the surrendered Security.

     If there shall be  delivered to the Company and to the Trustee (i) evidence
to their  satisfaction  of the  destruction,  loss or theft of any  Security  or
coupon,  and (ii) such  security or indemnity as may be required by them to save
each of them and any agent of either of them  harmless,  then, in the absence of
notice to the  Company  or the  Trustee  that such  Security  or coupon has been
acquired  by a bona fide  purchaser,  the  Company  shall  execute  and upon its
request  the  Trustee  shall  authenticate  and  deliver,  in lieu  of any  such
destroyed,  lost or stolen  Security or in exchange  for the Security to which a
destroyed,  lost or stolen coupon  appertains (with all appurtenant  coupons not
destroyed,  lost or stolen),  a new  Security  of the same series and  principal
amount,  containing  identical  terms and  provisions  and  bearing a number not
contemporaneously  outstanding,  with coupons  corresponding to the coupons,  if
any, appertaining to such destroyed,  lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

     Notwithstanding the provisions of the previous two paragraphs,  in case any
such  mutilated,  destroyed,  lost or stolen Security or coupon has become or is
about to become due and payable,  the Company in its discretion may,  instead of
issuing a new  Security,  with coupons  corresponding  to the  coupons,  if any,
appertaining  to such  destroyed,  lost or stolen Security or to the Security to
which such  destroyed,  lost or stolen coupon  appertains,  pay such Security or
coupon;  provided,  however, that payment of principal of (and premium, if any),
any interest on and any  Additional  Amounts with respect to, Bearer  Securities
shall,  except as  otherwise  provided in Section  1002,  be payable  only at an
office or agency  located  outside  the  United  States  and,  unless  otherwise
specified as  contemplated  by Section  301,  any interest on Bearer  Securities
shall  be  payable  only  upon   presentation   and  surrender  of  the  coupons
appertaining thereto.

     Upon the issuance of any new Security  under this Section,  the Company may
require the payment of a sum  sufficient to cover any tax or other  governmental
charge that may be imposed in relation thereto and any other expenses (including
the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series with its coupons,  if any, issued pursuant
to this  Section  in lieu of any  destroyed,  lost  or  stolen  Security,  or in
exchange for a Security to which a destroyed,  lost or stolen coupon appertains,
shall constitute an original additional  contractual  obligation of the Company,
whether or not the destroyed,  lost or stolen Security and its coupons,  if any,
or the  destroyed,  lost or stolen  coupon shall be at any time  enforceable  by
anyone,  and shall be entitled to all the benefits of this Indenture equally and
proportionately  with any and all  other  Securities  of that  series  and their
coupons, if any, duly issued hereunder.

     The  provisions of this Section are  exclusive  and shall  preclude (to the
extent lawful) all other rights and remedies with respect to the  replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons.

               SECTION 307.  Payment of  Interest;  Interest  Rights  Preserved.
          Except as otherwise  specified  with respect to a series of Securities
          in  accordance  with the  provisions  of Section 301,  interest on any
          Registered  Security that is payable,  and is punctually  paid or duly
          provided for, on any Interest Payment Date shall be paid to the Person
          in whose name that Security (or one or more Predecessor Securities) is
          registered  at the close of business  on the  Regular  Record Date for
          such  interest at the office or agency of the Company  maintained  for
          such purpose pursuant to Section 1002;  provided,  however,  that each
          installment  of  interest  on  any  Registered  Security  may  at  the
          Company's  option be paid by (i)  mailing  a check for such  interest,
          payable to or upon the written  order of the Person  entitled  thereto
          pursuant  to Section  308, to the address of such Person as it appears
          on the Security Register or (ii) transfer to an account  maintained by
          the payee located inside the United States.

     Unless  otherwise  provided as  contemplated by Section 301 with respect to
the Securities of any series,  payment of interest may be made, in the case of a
Bearer Security,  by transfer to an account  maintained by the payee with a bank
located outside the United States.

     Unless  otherwise  provided as contemplated by Section 301, every permanent
global  Security  will provide that  interest,  if any,  payable on any Interest
Payment Date will be paid to DTC,  Euroclear  and/or CEDEL,  as the case may be,
with  respect to that portion of such  permanent  global  Security  held for its
account  by Cede & Co. or the  Common  Depositary,  as the case may be,  for the
purpose  of  permitting  such  party to credit the  interest  received  by it in
respect of such  permanent  global  Security to the  accounts of the  beneficial
owners thereof.

     In case a Bearer  Security of any series is  surrendered  in exchange for a
Registered  Security of such series after the close of business (at an office or
agency in a Place of Payment  for such  series) on any  Regular  Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest  Payment Date,  such Bearer  Security shall be surrendered  without the
coupon  relating to such Interest  Payment Date and interest will not be payable
on such Interest  Payment Date in respect of the Registered  Security  issued in
exchange  for such Bearer  Security,  but will be payable  only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

     Except as otherwise  specified  with respect to a series of  Securities  in
accordance  with the  provisions of Section 301, any interest on any  Registered
Security  of any series  that is  payable,  but is not  punctually  paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted  Interest")
shall  forthwith  cease to be payable to the  registered  Holder  thereof on the
relevant  Regular  Record  Date by virtue of having been such  Holder,  and such
Defaulted Interest may be paid by the Company,  at its election in each case, as
provided in clause (1) or (2) below:

               (1) The  Company  may  elect  to make  payment  of any  Defaulted
          Interest to the Persons in whose names the  Registered  Securities  of
          such  series  (or  their   respective   Predecessor   Securities)  are
          registered  at the close of business on a Special  Record Date for the
          payment  of such  Defaulted  Interest,  which  shall  be  fixed in the
          following  manner.  The Company shall notify the Trustee in writing of
          the  amount  of  Defaulted  Interest  proposed  to  be  paid  on  each
          Registered  Security  of  such  series  and the  date of the  proposed
          payment  (which  shall not be less than 30 days after  such  notice is
          received  by the  Trustee),  and at the same  time the  Company  shall
          deposit  with the  Trustee  an  amount  of money  in the  currency  or
          currencies, currency unit or units or composite currency or currencies
          in  which  the  Securities  of such  series  are  payable  (except  as
          otherwise specified pursuant to Section 301 for the Securities of such
          series) equal to the aggregate  amount  proposed to be paid in respect
          of such Defaulted Interest or shall make arrangements  satisfactory to
          the Trustee for such  deposit on or prior to the date of the  proposed
          payment, such money when deposited to be held in trust for the benefit
          of the Persons  entitled to such Defaulted  Interest as in this clause
          provided.  Thereupon the Trustee  shall fix a Special  Record Date for
          the payment of such Defaulted Interest which shall be not more than 15
          days and not  less  then 10 days  prior  to the  date of the  proposed
          payment  and not less than 15 days after the receipt by the Trustee of
          the notice of the proposed payment.  The Trustee shall promptly notify
          the  Company of such  Special  Record Date and, in the name and at the
          expense of the Company,  shall cause notice of the proposed payment of
          such  Defaulted  Interest and the Special  Record Date  therefor to be
          mailed,  first class  postage  prepaid,  to each Holder of  Registered
          Securities of such series at his address as it appears in the Security
          Register not less than 10 days prior to such Special  Record Date. The
          Company may, in its  discretion,  direct the Trustee to publish in the
          name and at the expense of the Company,  cause a similar  notice to be
          published  at least once in an  Authorized  Newspaper in each Place of
          Payment,  but such publications shall not be a condition  precedent to
          the  establishment of such Special Record Date. Notice of the proposed
          payment  of such  Defaulted  Interest  and  the  Special  Record  Date
          therefor  having been mailed as  aforesaid,  such  Defaulted  Interest
          shall be paid to the Persons in whose names the Registered  Securities
          of such  series  (or  their  respective  Predecessor  Securities)  are
          registered  at the close of business on such  Special  Record Date and
          shall no longer be payable  pursuant to the  following  clause (2). In
          case a Bearer  Security of any series is  surrendered at the office or
          agency  in a Place  of  Payment  for such  series  in  exchange  for a
          Registered Security of such series after the close of business at such
          office or agency on any Special  Record Date and before the opening of
          business  at such office or agency on the  related  proposed  date for
          payment  of  Defaulted   Interest,   such  Bearer  Security  shall  be
          surrendered  without  the coupon  relating  to such  proposed  date of
          payment and  Defaulted  Interest  will not be payable on such proposed
          date of  payment  in  respect  of the  Registered  Security  issued in
          exchange  for such Bearer  Security,  but will be payable  only to the
          Holder of such coupon when due in  accordance  with the  provisions of
          this Indenture; or

               (2) The Company may make payment of any Defaulted Interest on the
          Registered  Securities  of any series in any other  lawful  manner not
          inconsistent with the requirements of any securities exchange on which
          such Securities may be listed, and upon such notice as may be required
          by such exchange, if, after notice given by the Company to the Trustee
          of the  proposed  payment  pursuant  to this  clause,  such  manner of
          payment shall be deemed practicable by the Trustee.

     Subject to the  foregoing  provisions of this Section and Section 305, each
Security  delivered under this Indenture upon  registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

               SECTION 308. Persons Deemed Owners. Prior to due presentment of a
          Registered  Security for  registration of transfer,  the Company,  the
          Trustee  and any agent of the  Company  or the  Trustee  may treat the
          Person in whose name such  Registered  Security is  registered  as the
          owner  of such  Security  for the  purpose  of  receiving  payment  of
          principal of (and premium,  if any),  and (subject to Sections 305 and
          307) interest on, such Registered  Security and for all other purposes
          whatsoever,  whether or not such Registered  Security be overdue,  and
          neither the  Company,  the Trustee nor any agent of the Company or the
          Trustee shall be affected by notice to the contrary.

     Title to any Bearer  Security and any coupons  appertaining  thereto  shall
pass by delivery.  The Company,  the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the  absolute  owner of such  Security or coupon for the purpose of receiving
payment  thereof or on account  thereof and for all other  purposes  whatsoever,
whether or not such Security or coupon be overdue,  and neither the Company, the
Trustee nor any agent of the Company or the Trustee  shall be affected by notice
to the contrary.

     None  of the  Company,  the  Trustee,  any  Paying  Agent  or the  Security
Registrar  will  have any  responsibility  or  liability  for any  aspect of the
records  relating  to or  payments  made  on  account  of  beneficial  ownership
interests  of a  Security  in global  form or for  maintaining,  supervising  or
reviewing any records relating to such beneficial ownership interests.

     Notwithstanding the foregoing, with respect to any global Security, nothing
herein shall  prevent the Company,  the Trustee,  or any agent of the Company or
the Trustee,  from giving  effect to any written  certification,  proxy or other
authorization  furnished by any  depositary,  as a Holder,  with respect to such
global  Security or impair,  as between such depositary and owners of beneficial
interests  in  such  global  Security,  the  operation  of  customary  practices
governing  the  exercise of the rights of such  depositary  (or its  nominee) as
Holder of such global Security.

               SECTION 309. Cancellation. All Securities and coupons surrendered
          for  payment,  redemption,  repayment  at the  option  of the  Holder,
          registration of transfer or exchange or for credit against any sinking
          fund  payment  shall,  if  surrendered  to any  Person  other than the
          Trustee,  be  delivered to the Trustee,  and any such  Securities  and
          coupons and Securities and coupons surrendered directly to the Trustee
          for any such  Purpose  shall be promptly  cancelled  by it;  provided,
          however,  where the Place of Payment is located  outside of the United
          States,  the  Paying  Agent at such  Place of  Payment  may cancel the
          Securities surrendered to it for such purposes prior to delivering the
          Securities to the Trustee.  The Company may at any time deliver to the
          Trustee for cancellation any Securities  previously  authenticated and
          delivered  hereunder which the Company may have acquired in any manner
          whatsoever, and may deliver to the Trustee (or to any other Person for
          delivery to the Trustee) for  cancellation  any Securities  previously
          unauthenticated  hereunder  which the Company has not issued and sold,
          and all  Securities  so delivered  shall be promptly  cancelled by the
          Trustee.  If the  Company  shall  so  acquire  any of the  Securities,
          however,  such  acquisition  shall  not  operate  as a  redemption  or
          satisfaction of the indebtedness represented by such Securities unless
          and until the same are surrendered to the Trustee for cancellation. No
          Securities  shall be  authenticated  in lieu of or in exchange for any
          Securities cancelled as provided in this Section,  except as expressly
          permitted by this Indenture.  Cancelled Securities and coupons held by
          the Trustee  shall be destroyed  by the Trustee and the Trustee  shall
          deliver a certificate of such destruction to the Company,  unless by a
          Company Order the Company directs their return to it.

               SECTION  310.  Computation  of  Interest.   Except  as  otherwise
          specified as contemplated by Section 301 with respect to Securities of
          any  series,  interest  on the  Securities  of each  series  shall  be
          computed on the basis of a 360-day year  consisting  of twelve  30-day
          months.

                                  ARTICLE FOUR

                           SATISFACTION AND DISCHARGE

          with  respect to any series of  Securities  specified  in such Company
          Request (except as to any surviving rights of registration of transfer
          or exchange of Securities of such series herein expressly provided for
          and any right to receive  Additional  Amounts,  as provided in Section
          1011),  and the Trustee,  upon receipt of a Company Order,  and at the
          expense of the Company, shall execute proper instruments acknowledging
          satisfaction and discharge of this Indenture as to such series when

                    (1)      either

                         (A)  all   Securities   of  such   series   theretofore

                    Bearer  Securities  surrendered  for exchange for Registered
                    Securities and maturing after such exchange, whose surrender
                    is not  required  or has been  waived as provided in Section
                    305, (ii)  Securities  and coupons of such series which have
                    been destroyed,  lost or stolen and which have been replaced

                    has been  waived  as  provided  in  Section  1106,  and (iv)
                    Securities  and  coupons of such  series  for whose  payment
                    money has theretofore  been deposited in trust or segregated

                    the Company or  discharged  from such trust,  as provided in
                    Section  1003)  have  been  delivered  to  the  Trustee  for
                    cancellation; or

                    (i) or (ii)  below,  any  coupons  appertaining  thereto not
                    theretofore delivered to the Trustee for cancellation

                         (i) have become due and payable, or

                    to  be  called   for   redemption   within  one  year  under
                    arrangements  satisfactory  to the Trustee for the giving of
                    notice of redemption by the Trustee in the name,  and at the
                    expense, of the Company,

          and the  Company,  in the  case  of (i),  (ii)  or  (iii)  above,  has
          irrevocably  deposited or caused to be  deposited  with the Trustee as
          trust  funds in trust for the  purpose  an amount in the  currency  or
          currencies, currency unit or units or composite currency or currencies

          and  discharge the entire  indebtedness  on such  Securities  and such
          coupons not theretofore delivered to the Trustee for cancellation, for
          principal  (and  premium,  if any) and  interest,  and any  Additional
          Amounts with respect thereto, to the date of such deposit (in the case
          of  Securities  which have  become due and  payable)  or to the Stated
          Maturity or Redemption Date, as the case may be;

          (2) the Company  has paid or caused to be paid all other sums  payable
     hereunder by the Company; and

          (3) the Company has  delivered to the Trustee an Officers  Certificate
     and an Opinion of  Counsel,  each  stating  that all  conditions  precedent
     herein  provided for  relating to the  satisfaction  and  discharge of this
     Indenture as to such series have been complied with.

Notwithstanding   the  satisfaction   and  discharge  of  this  Indenture,   the
obligations  of the  Company to the Trustee and any  predecessor  Trustee  under
Section 606, the  obligations of the Company to any  Authenticating  Agent under

               the Securities,  the coupons and this Indenture,  to the payment,
               either  directly  or through  any  Paying  Agent  (including  the
               Company  acting  as its own  Paying  Agent)  as the  Trustee  may
               determine, to the Persons entitled thereto, of the principal (and
               premium,  if any),  and any interest and  Additional  Amounts for

               the  Trustee,  but such money need not be  segregated  from other
               funds except to the extent required by law.

               Annulment.  If an Event of Default other than an Event of Default
               specified in Section  501(6) or (7) with respect to Securities of
               any series at the time Outstanding occurs and is continuing, then
               and in every  such case the  Trustee  or the  Holders of not less
               than 25% in principal  amount of the  Outstanding  Securities  of
               that series may declare the principal  (or, if any Securities are
               Original Issue Discount  Securities or Indexed  Securities,  such
               portion  of  the  principal  as  may be  specified  in the  terms
               thereof)  of all  the  Securities  of that  series  to be due and
               payable  immediately,  by a notice in writing to the Company (and
               to the  Trustee  it  given  by the  Holders),  and  upon any such
               declaration  such  principal or specified  portion  thereof shall
               become immediately due and payable;  provided,  however,  that if
               such Event of Default shall occur  pursuant to Section  501(6) or
               Section 501(7) hereof,  such acceleration  shall be automatic and
               shall occur without notice.

     At any time  after  such a  declaration  of  acceleration  with  respect to
Securities  of any  series  has been made and  before a  judgment  or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article  provided,  the  Holders  of a  majority  in  principal  amount  of  the
Outstanding  Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

                    (1) the Company has paid or deposited with the Trustee a sum
               sufficient  to pay in the currency or currency  unit or composite
               currency  in which the  Securities  of such  series  are  payable
               (except as  otherwise  specified  Pursuant to Section 301 for the
               Securities of such series):

                         (A) all  overdue  installments  of  interest on and any
                    Additional  Amounts  payable in  respect of all  Outstanding
                    Securities of that series and any related coupons;

                         (B) the  principal  of (and  premium,  if any,  on) any
                    Outstanding  Securities of that series which have become due
                    otherwise  than  by such  declaration  of  acceleration  and
                    interest  thereon at the rate or rates  borne by or provided
                    for in such Securities;

                         (C) to the  extent  that  payment of such  interest  is
                    lawful,  interest upon overdue  installments of interest and
                    any  Additional  Amounts  at the rate or  rates  borne by or
                    provided for in such Securities; and

                         (D) all sums paid or advanced by the Trustee  hereunder
                    and the reasonable compensation, expenses, disbursements and
                    advances of the Trustee, its agents and counsel; and

                    (2) all Events of Default with respect to Securities of that
               series,  other  than  the  nonpayment  of  the  principal  of (or
               premium,  if any) or interest on  Securities of that series which
               have become due solely by such declaration of acceleration,  have
               been cured or waived as provided in Section 513.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent thereon.

                    SECTION  503.  Collection  of  Indebtedness  and  Suits  for
               Enforcement by Trustee. The Company covenants that if:

                    (1)  default is made in the  payment of any  installment  of
               interest or  Additional  Amounts,  if any, on any Security of any
               series and any related  coupon when such  interest or  Additional
               Amount  becomes due and payable and such default  continues for a
               period of 30 days; or

                    (2) default is made in the payment of the  principal  of (or
               premium, if any, on) any Security of any series at its Maturity,

then the Company will, upon demand of the Trustee,  pay to the Trustee,  for the
benefit of the Holders of such Securities of such series and coupons,  the whole
amount then due and payable on such  Securities  and coupons for principal  (and
premium,  if any) and interest and  Additional  Amounts,  with interest upon any
overdue principal (and premium,  if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of interest
or Additional  Amounts, if any, at the rate or rates borne by or provided for in
such  Securities,  and, in addition  thereto,  such  further  amount as shall be
sufficient  to cover  the  costs  and  expenses  of  collection,  including  the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel.

     If the Company fails to pay such amounts  forthwith  upon such demand,  the
Trustee,  in its own name and as trustee of an express  trust,  may  institute a
judicial  proceeding for the  collection of the sums so due and unpaid,  and may
prosecute such proceeding to judgment or final decree,  and may enforce the same
against the Company or any other obligor upon such Securities of such series and
collect the monies  adjudged or decreed to be payable in the manner  provided by
law out of the property of the Company or any other obligor upon such Securities
of such series, wherever situated.

     If an Event of Default with respect to  Securities of any series occurs and
is continuing,  the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the  Holders of  Securities  of such series and any
related coupons by such  appropriate  judicial  proceedings as the Trustee shall
deem most  effectual  to protect and enforce  any such  rights,  whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

               SECTION  504.  Trustee May File  Proofs of Claim.  In case of the
          pendency of any  receivership,  insolvency,  liquidation,  bankruptcy,
          reorganization, arrangement, adjustment, composition or other judicial
          proceeding  relative  to the  Company  or any other  obligor  upon the
          Securities  or the property of the Company or of such other obligor or
          their creditors, the Trustee (irrespective of whether the principal of
          the  Securities of any series shall then be due and payable as therein
          expressed or by declaration or otherwise and  irrespective  of whether
          the Trustee  shall have made any demand on the Company for the payment
          of overdue principal,  premium, if any, or interest) shall be entitled
          and empowered, by intervention in such proceeding or otherwise:

                    (i) to file and prove a claim for the whole amount,  or such
               lesser  amount as may be provided for in the  Securities  of such
               series,  of  principal  (and  premium,  if any) and  interest and
               Additional  Amounts,  if any,  owing and unpaid in respect of the
               Securities  and to file such other  papers or documents as may be
               necessary or advisable in order to have the claims of the Trustee
               (including any claim for the reasonable  compensation,  expenses,
               disbursements  and  advances  of  the  Trustee,  its  agents  and
               counsel) and of the Holders allowed in such judicial  proceeding;
               and

                    (ii) to collect  and  receive  any monies or other  property
               payable or  deliverable  on any such claims and to distribute the
               same,

and any custodian,  receiver,  assignee, trustee,  liquidator,  sequestrator (or
other similar official) in any such judicial  proceeding is hereby authorized by
each Holder of  Securities  of such series and coupons to make such  payments to
the Trustee,  and in the event that the Trustee  shall  consent to the making of
such payments  directly to the Holders,  to pay to the Trustee any amount due to
it for the reasonable compensation,  expenses, disbursements and advances of the
Trustee and any  predecessor  Trustee,  their agents and counsel,  and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

     Nothing  herein  contained  shall be deemed to  authorize  the  Trustee  to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or coupon any plan of  reorganization,  arrangement,  adjustment or  composition
affecting the Securities or coupons or the rights of any Holder  thereof,  or to
authorize  the  Trustee  to vote in  respect  of the  claim of any  Holder  of a
Security or coupon in any such proceeding.

               SECTION 505.  Trustee May Enforce  Claims  Without  Possession of
          Securities  or  Coupons.  All rights of action  and claims  under this
          Indenture or any of the  Securities or coupons may be  prosecuted  and
          enforced  by  the  Trustee  without  the  possession  of  any  of  the
          Securities  or coupons  or the  production  thereof in any  proceeding
          relating  thereto,  and any such proceeding  instituted by the Trustee
          shall be brought in its own name as trustee of an express  trust,  and
          any recovery of judgment shall, after provision for the payment of the
          reasonable compensation,  expenses,  disbursements and advances of the
          Trustee,  its agents and  counsel,  be for the ratable  benefit of the
          Holders  of the  Securities  and  coupons  in  respect  of which  such
          judgment has been recovered.

               SECTION 506. Application of Money Collected.  Any money collected
          by the  Trustee  pursuant  to this  Article  shall be  applied  in the
          following  order,  at the date or dates fixed by the  Trustee  and, in
          case of the  distribution  of such money on account of  principal  (or
          premium,  if  any)  or  interest  and  any  Additional  Amounts,  upon
          presentation  of the  Securities or coupons,  or both, as the case may
          be, and the notation thereon of the payment if only partially paid and
          upon surrender thereof if fully paid:

               FIRST:  To the  payment of all  amounts  due the  Trustee and any
          predecessor Trustee under Section 606;

               SECOND:  To the payment of the  amounts  then due and unpaid upon
          the  Securities  and coupons for principal  (and premium,  if any) and
          interest and any Additional Amounts payable,  in respect,  of which or
          for the  benefit  of which  such  money has been  collected,  ratably,
          without preference or priority of any kind, according to the aggregate
          amounts due and payable on such  Securities  and coupons for principal
          (and premium, if any), interest and Additional Amounts,  respectively;
          and

               THIRD: To the payment of the remainder, if any, to the Company.

               SECTION 507.  Limitation  on Suits.  No Holder of any Security of
          any series or any related coupon shall have any right to institute any
          proceeding,  judicial or otherwise, with respect to this Indenture, or
          for the appointment of a receiver or trustee,  or for any other remedy
          hereunder, unless:

                    (1) such Holder has  previously  given written notice to the
               Trustee  of a  continuing  Event of Default  with  respect to the
               Securities of that series;

                    (2) the Holders of not less than 25% in principal  amount of
               the Outstanding Securities of that series shall have made written
               request to the  Trustee to  institute  proceedings  in respect of
               such Event of Default in its own name as Trustee hereunder;

                    (3) such  Holder or  Holders  have  offered  to the  Trustee
               indemnity  reasonably  satisfactory  to the Trustee,  in its sole
               discretion,  against the costs,  expenses and  liabilities  to be
               incurred in compliance with such request;

                    (4)  the  Trustee  for 60 days  after  its  receipt  of such
               notice,  request and offer of  indemnity  has failed to institute
               any such proceeding; and

                    (5) no direction  inconsistent with such written request has
               been  given to the  Trustee  during  such  60-day  period  by the
               Holders  of a majority  in  principal  amount of the  Outstanding
               Securities of that series;

it being  understood and intended that no one or more of such Holders shall have
any right in any manner  whatever by virtue of, or by availing of, any provision
of this  Indenture to affect,  disturb or  prejudice  the rights of any other of
such Holders,  or to obtain or to seek to obtain priority or preference over any
other of such  Holders or to enforce any right under this  Indenture,  except in
the manner  herein  provided  and for the equal and ratable  benefit of all such
Holders.

               SECTION 508. Unconditional Right of Holders to Receive Principal,
          Premium, if any, Interest and Additional Amounts.  Notwithstanding any
          other  provision  in this  Indenture,  the Holder of any  Security  or
          coupon  shall have the right which is absolute  and  unconditional  to
          receive payment of the principal of (and premium, if any) and (subject
          to Sections 305 and 307)  interest on, and any  Additional  Amounts in
          respect of, such Security or payment of such coupon on the  respective
          due dates  expressed  in such  Security  or coupon (or, in the case of
          redemption,  on the  Redemption  Date) and to  institute  suit for the
          enforcement of any such payment, and such rights shall not be impaired
          without the consent of such Holder.

               SECTION 509.  Restoration of Rights and Remedies.  If the Trustee
          or any Holder of a Security or coupon has instituted any proceeding to
          enforce any right or remedy under this  Indenture and such  proceeding
          has  been  discontinued  or  abandoned  for any  reason,  or has  been
          determined  adversely  to the Trustee or to such  Holder,  then and in
          every  such  case,  the  Company,  the  Trustee  and  the  Holders  of
          Securities and coupons  shall,  subject to any  determination  in such
          proceeding,  be restored  severally and  respectively  to their former
          positions  hereunder  and  thereafter  all rights and  remedies of the
          Trustee and the Holders  shall  continue as though no such  proceeding
          had been instituted.

               SECTION 510. Rights and Remedies Cumulative.  Except as otherwise
          provided  with  respect to the  replacement  or payment of  mutilated,
          destroyed,  lost or stolen Securities or coupons in the last paragraph
          of Section 306, no right or remedy herein  conferred  upon or reserved
          to the Trustee or to the Holders of  Securities or coupons is intended
          to be  exclusive  of any other  right or remedy,  and every  right and
          remedy shall,  to the extent  permitted by law, be  cumulative  and in
          addition  to every other right and remedy  given  hereunder  or now or
          hereafter existing at law or in equity or otherwise.  The assertion or
          employment of any right or remedy hereunder,  or otherwise,  shall not
          prevent  the   concurrent   assertion  or   employment  of  any  other
          appropriate right or remedy.

               SECTION 511.  Delay or Omission Not Waiver.  No delay or omission
          of the Trustee or of any Holder of any  Security or coupon to exercise
          any right or remedy  accruing  upon any Event of Default  shall impair
          any such right or remedy or  constitute  a waiver of any such Event of
          Default or an  acquiescence  therein.  Every right and remedy given by
          this  Article  or by law  to the  Trustee  or to  the  Holders  may be
          exercised from time to time, and as often as may be deemed  expedient,
          by the Trustee or by the Holders of Securities or coupons, as the case
          may be.

               SECTION 512. Control by Holders of Securities. The Holders of not
          less than a majority in principal amount of the Outstanding Securities
          of any  series  shall  have the right to direct  the time,  method and
          place of conducting  any  proceeding  for any remedy  available to the
          Trustee or exercising any trust or power conferred on the Trustee with
          respect to the Securities of such series, provided that:

                    (1) such direction shall not be in conflict with any rule of
               law or with this Indenture;

                    (2) the Trustee may take any other action  deemed  proper by
               the Trustee which is not inconsistent with such direction; and

                    (3) the Trustee need not take any action which might involve
               it in personal  liability or be unduly prejudicial to the Holders
               of Securities of such series not joining therein.

               SECTION  513.  Waiver of Past  Defaults.  The Holders of not less
          than a majority in principal  amount of the Outstanding  Securities of
          any series may on behalf of the Holders of all the  Securities of such
          series and any related  coupons waive any past default  hereunder with
          respect to such series and its consequences, except a default:

                    (1) in the payment of the principal of (or premium,  if any)
               or interest on or  Additional  Amounts  payable in respect of any
               Security of such series or any related coupons; or

                    (2) in respect of a covenant or provision hereof which under
               Article Nine cannot be modified or amended without the consent of
               the Holder of each Outstanding Security of such series affected.

     Upon any such waiver,  such default shall cease to exist,  and any Event of
Default arising  therefrom shall be deemed to have been cured, for every purpose
of this  Indenture;  but no such waiver shall extend to any  subsequent or other
default or Event of Default or impair any right consequent thereon.

               SECTION 514. Waiver of Usury, Stay or Extension Laws. The Company
          covenants  (to the extent that it may lawfully do so) that it will not
          at any time insist upon, or plead, or in any manner  whatsoever  claim
          or take the benefit or advantage of, any usury,  stay or extension law
          wherever  enacted,  now or at any time  hereafter in force,  which may
          affect the covenants or the  performance  of this  Indenture;  and the
          Company  (to the extent that it may  lawfully do so) hereby  expressly
          waives all benefit or advantage of any such law, and covenants that it
          will not hinder,  delay or impede the  execution  of any power  herein
          granted to the  Trustee,  but will suffer and permit the  execution of
          every such power as though no such law had been enacted.

               SECTION 515. Undertaking for Costs. All parties to this Indenture
          agree, and each Holder of any Security by his acceptance thereof shall
          be  deemed  to have  agreed,  that  any  court  may in its  discretion
          require,  in any suit for the enforcement of any right or remedy under
          this  Indenture,  or in any suit  against  the  Trustee for any action
          taken or omitted by it as Trustee, the filing by any party litigant in
          such suit of any  undertaking  to pay the costs of such suit, and that
          such court may in its discretion assess  reasonable  costs,  including
          reasonable  attorneys'  fees,  against any party litigant in such suit
          having  due  regard  to the  merits  and good  faith of the  claims or
          defenses  made by such  party  litigant;  but the  provisions  of this
          Section shall not apply to any suit instituted by the Trustee,  to any
          suit  instituted  by any Holder,  or group of Holders,  holding in the
          aggregate  more  than  10% in  principal  amount  of  the  Outstanding
          Securities,   or  to  any  suit  instituted  by  any  Holder  for  the
          enforcement of the payment of the principal of (or premium, if any) or
          interest on any Security on or after the respective  Stated Maturities
          expressed in such Security (or, in the case of redemption, on or after
          the Redemption Date).

                                   ARTICLE SIX

                                   THE TRUSTEE

               SECTION  601.  Notice  of  Defaults.  Within  90 days  after  the
          occurrence of any default  hereunder with respect to the Securities of
          any series, the Trustee shall transmit in the manner and to the extent
          provided in TIA Section 313(c), notice of such default hereunder known
          to the Trustee,  unless such default  shall have been cured or waived;
          provided,  however,  that,  except  in the  case of a  default  in the
          payment of the principal of (or premium, if any) or interest on or any
          Additional  Amounts with respect to any Security of such series, or in
          the  payment  of any  sinking  fund  installment  with  respect to the
          Securities  of  such  series,   the  Trustee  shall  be  protected  in
          withholding such notice if and so long as Responsible  Officers of the
          Trustee in good faith determine that the withholding of such notice is
          in the interests of the Holders of the  Securities and coupons of such
          series; and provided further that in the ease of any default or breach

          Securities and coupons of such series, no such notice to Holders shall
          be given until at least 60 days after the occurrence thereof.  For the
          purpose of this Section,  the term "default" means any event which is,
          or after  notice or lapse of time or both  would  become,  an Event of
          Default with respect to the Securities of such series.

               request or direction of any of the Holders of  Securities  of any
               series or any related coupons pursuant to this Indenture,  unless

               indemnity  reasonably  satisfactory  to the  Trustee  against the
               costs,  expenses and liabilities which might be incurred by it in

               direction, consent, order, bond, debenture, note, coupon or other
               paper or document,  but the Trustee, in its discretion,  may make
               such further inquiry or investigation  into such facts or matters
               as it may see fit,  and, if the Trustee  shall  determine to make
               such further  inquiry or  investigation,  it shall be entitled to
               make reasonable examination of the books, records and premises of
               the  Company,  personally  or  by  agent  or  attorney  following
               reasonable notice to the Company;

                    (7) the  Trustee  may  execute  any of the  trusts or Powers
               hereunder or perform any duties  hereunder  either directly or by
               or  through  agents or  attorneys  and the  Trustee  shall not be
               responsible for any willful  misconduct or negligence on the part
               of any agent or attorney appointed with due care by it hereunder;

               provisions  of Sections  601 and 602,  the  Trustee  shall not be
               deemed to have  notice or  knowledge  of any  default or Event of
               Default  (other than under Section  501(1),  (2) or (3)) unless a
               Responsible  Officer  assigned  to and  working in the  Trustee's
               Corporate  Trust  Office has actual  knowledge  thereof or unless
               written  notice of any default or Event of Default is received by
               the Trustee at the Corporate  Trust Office and such notice refers
               to the Securities generally, the Company or this Indenture; and

                    (10) the Trustee shall not be required to expend or risk its
               own funds or  otherwise  incur  any  financial  liability  in the
               performance of any of its duties hereunder, or in the exercise of
               any of its rights or power, if it shall have  reasonable  grounds
               for believing that repayment of such funds or adequate  indemnity
               against such risk or liability is not reasonably assured to it.

     Except  during  the  continuance  of  an  Event  of  Default,  the  Trustee
undertakes  to perform  only such duties as are  specifically  set forth in this
Indenture,  and no  implied  covenants  or  obligations  shall be read into this
Indenture against the Trustee.

               SECTION  603.  Not   Responsible  for  Recitals  or  Issuance  of
          Securities.  The  recitals  contained  herein  and in the  Securities,
          except the Trustee's certificate of authentication, and in any coupons
          shall be taken as the  statements  of the  Company,  and  neither  the
          Trustee nor any  Authenticating  Agent assumes any  responsibility for
          their  correctness.  The Trustee  makes no  representations  as to the
          validity or  sufficiency  of this  Indenture or of the  Securities  or
          coupons, except that the Trustee represents that it is duly authorized
          to execute and deliver this Indenture, authenticate the Securities and
          perform  its  obligations  hereunder.  Neither  the  Trustee  nor  any
          Authenticating  Agent shall be accountable  for the use or application
          by the Company of Securities or the proceeds thereof.

               SECTION 604. May Hold Securities.  The Trustee, any Paying Agent,
          Security  Registrar,  Authenticating  Agent or any other  agent of the
          Company, in its individual or any other capacity, may become the owner
          or pledgee of  Securities  and coupons  and,  subject to TIA  Sections
          310(b) and 311,  may  otherwise  deal with the  Company  with the same
          rights it would have if it were not Trustee,  Paying  Agent,  Security
          Registrar, Authenticating Agent or such other agent.

               SECTION  605.  Money Held in Trust.  Money held by the Trustee in
          trust  hereunder need not be segregated from other funds except to the
          extent  required by law. The Trustee  shall be under no liability  for
          interest on any money  received by it  hereunder  except as  otherwise
          agreed with the Company.

               SECTION 606. Compensation and Reimbursement. The Company agrees:

                    (1) to pay to the  Trustee  from  time  to  time  reasonable
               compensation  for all services  rendered by it  hereunder  (which
               compensation  shall not be  limited  by any  provision  of law in
               regard to the compensation of a trustee of in express trust);

                    (2)  except  as  otherwise  expressly  provided  herein,  to
               reimburse  each of the Trustee and any  predecessor  Trustee upon
               its  request  for  all  reasonable  expenses,  disbursements  and
               advances  incurred or made by the Trustee in accordance  with any
               provision   of   this   Indenture   (including   the   reasonable
               compensation and the expenses and disbursements of its agents and
               counsel), except any such expense, disbursement or advance as may
               be attributable to its negligence or willful misconduct; and

                    (3) to  indemnify  each of the Trustee  and any  predecessor
               Trustee for, and to hold it harmless against, any loss, liability
               or expense incurred without  negligence or willful  misconduct on
               its own part, arising out of or in connection with the acceptance
               or administration of the trust or trusts hereunder, including the
               costs and  expenses  of  defending  itself  against  any claim or
               liability in connection  with the exercise or  performance of any
               of its powers or duties hereunder.

     When the Trustee incurs expenses or renders  services in connection with an
Event of Default  specified in Section  501(6) or Section  501(7),  the expenses
(including  the  reasonable  charges  and  expenses  of  its  counsel)  and  the
compensation   for  the  services  are  intended  to   constitute   expenses  of
administration  under any applicable Federal or state bankruptcy,  insolvency or
other similar law.

     As security for the  performance  of the  obligations  of the Company under
this  Section,  the Trustee shall have a lien prior to the  Securities  upon all
property and funds held or  collected by the Trustee as such,  except funds held
in trust for the payment of  principal  of (or  premium,  if any) or interest on
particular Securities or any coupons.

     The  provisions  of this  Section  shall  survive the  termination  of this
Indenture.

               SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
          Interests. There shall at all times be a Trustee hereunder which shall
          be eligible to act as Trustee  under TIA Section  310(a)(1)  and shall
          have a combined capital and surplus of at least  $50,000,000.  If such
          corporation publishes reports of condition at least annually, pursuant
          to law or the requirements of Federal, State,  Territorial or District
          of Columbia supervising or examining authority,  then for the purposes
          of this Section,  the combined capital and surplus of such corporation
          shall be deemed to be its combined capital and surplus as set forth in
          its most recent report of condition so  published.  If at any time the
          Trustee shall cease to be eligible in accordance  with the  provisions
          of this Section,  it shall resign  immediately  in the manner and with
          the effect hereinafter specified in this Article.

               SECTION 608.  Resignation and Removal;  Appointment of Successor.
          (1) No  resignation  or removal of the Trustee and no appointment of a
          successor  Trustee  pursuant to this Article  shall  become  effective
          until the  acceptance  of  appointment  by the  successor  Trustee  in
          accordance with the applicable requirements of Section 609.

               (2) The  Trustee  may  resign  at any time  with  respect  to the
          Securities of one or more series by giving  written  notice thereof to
          the Company.  If an instrument  of  acceptance by a successor  Trustee
          shall not have been  delivered to the Trustee within 30 days after the
          giving of such  notice  of  resignation,  the  resigning  Trustee  may
          petition any court of competent  jurisdiction for the appointment of a
          successor Trustee.

               (3) The  Trustee  may be removed at any time with  respect to the
          Securities  of any  series  by Act of the  Holders  of a  majority  in
          principal  amount  of  the  Outstanding   Securities  of  such  series
          delivered to the Trustee and to the Company.

               (4) If at any time:

                    (A) the Trustee shall fail to comply with the  provisions of
               TIA Section 310(b) after written request  therefor by the Company
               or by any Holder of a Security who has been a bona fide Holder of
               a Security for at least six months;

                    (B) the Trustee shall cease to be eligible under Section 608
               and shall fail to resign after  written  request  therefor by the
               Company or by any  Holder of a Security  who has been a bona fide
               Holder of a Security for at least six months; or

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove  the  Trustee  and  appoint  a  successor  Trustee  with  respect  to all
Securities,  or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others  similarly  situated,  petition any court of competent
jurisdiction  for the removal of the Trustee with respect to all  Securities and
the appointment of a successor Trustee or Trustees.

               (5) If the Trustee shall resign,  be removed or become  incapable
          of acting,  or if a vacancy  shall  occur in the office of Trustee for
          any cause with respect to the  Securities  of one or more series,  the
          Company, by or pursuant to a Board Resolution,  shall promptly appoint
          a successor Trustee or Trustees with respect to the Securities of that
          or those series (it being  understood that any such successor  Trustee
          may be appointed  with respect to the Securities of one or more or all
          of such  series and that at any time there  shall be only one  Trustee
          with respect to the Securities of any particular  series).  If, within
          one year  after such  resignation,  removal  or  incapability,  or the
          occurrence  of such vacancy,  a successor  Trustee with respect to the
          Securities of any series shall be appointed by Act of the Holders of a
          majority in principal  amount of the  Outstanding  Securities  of such
          series  delivered  to  the  Company  and  the  retiring  Trustee,  the
          successor Trustee so appointed shall, forthwith upon its acceptance of
          such  appointment,  become the  successor  Trustee with respect to the
          Securities  of such series and to that extent  supersede the successor
          Trustee appointed by the Company. If no successor Trustee with respect
          to the  Securities  of any series  shall have been so appointed by the
          Company or the Holders of Securities  and accepted  appointment in the
          manner hereinafter  provided,  any Holder of a Security who has been a
          bona fide  Holder of a Security of such series for at least six months
          may, on behalf of himself and all others similarly situated,  petition
          any court of competent jurisdiction for the appointment of a successor
          Trustee with respect to Securities of such series.

               (6) The Company  shall give notice of each  resignation  and each
          removal of the Trustee  with respect to the  Securities  of any series
          and each  appointment  of a  successor  Trustee  with  respect  to the
          Securities  of any series in the manner  provided  for  notices to the
          Holders of  Securities  in Section 106.  Each notice shall include the
          name of the successor  Trustee with respect to the  Securities of such
          series and the address of its Corporate Trust Office.

               SECTION 609. Acceptance of Appointment by Successor.  (1) In case
          of the  appointment  hereunder of a successor  Trustee with respect to
          all   Securities,   every  such   successor   Trustee  shall  execute,
          acknowledge and deliver to the Company and to the retiring  Trustee an
          instrument  accepting such appointment,  and thereupon the resignation
          or removal of the retiring  Trustee  shall become  effective  and such
          successor Trustee, without any further act, deed or conveyance,  shall
          become  vested with all the rights,  powers,  trusts and duties of the
          retiring  Trustee;  but,  on request of the  Company or the  successor
          Trustee,  such retiring  Trustee  shall,  upon payment of its charges,
          execute  and  deliver an  instrument  transferring  to such  successor
          Trustee all the rights, powers and trusts of the retiring Trustee, and
          shall duly assign,  transfer and deliver to such successor Trustee all
          property and money held by such retiring  Trustee  hereunder,  subject
          nevertheless to its claim, if any, provided for in Section 607.

               (2) In case of the appointment  hereunder of a successor  Trustee
          with  respect to the  Securities  of one or more (but not all) series,
          the Company,  the  retiring  Trustee and each  successor  Trustee with
          respect to the  Securities  of one or more  series  shall  execute and
          deliver an  indenture  supplemental  hereto,  pursuant to Article Nine
          hereof,  wherein each successor  Trustee shall accept such appointment
          and which (A) shall  contain such  provisions as shall be necessary or
          desirable to transfer  and confirm to, and to vest in, each  successor
          Trustee  all the  rights,  powers,  trusts and duties of the  retiring
          Trustee  with  respect to the  Securities  of that or those  series to
          which the appointment of such successor  Trustee  relates,  (B) if the
          retiring Trustee is not retiring with respect to all Securities, shall
          contain such  provisions as shall be deemed  necessary or desirable to
          confirm that all the rights, powers, trusts and duties of the retiring
          Trustee with respect to the  Securities  of that or those series as to
          which the retiring Trustee is not retiring shall continue to be vested
          in the  retiring  Trustee,  and (C) shall add to or change  any of the
          provisions  of this  Indenture as shall be necessary to provide for or
          facilitate the administration of the trusts hereunder by more than one
          Trustee,   it  being   understood  that  nothing  herein  or  in  such
          supplemental  indenture shall constitute such Trustees  co-trustees of
          the same trust and that each such Trustee  shall be trustee of a trust
          or  trusts  hereunder  separate  and  apart  from any  trust or trusts
          hereunder  administered  by any  other  such  Trustee;  and  upon  the
          execution and delivery of such supplemental  indenture the resignation
          or removal of the  retiring  Trustee  shall  become  effective  to the
          extent provided therein and each such successor  Trustee,  without any
          further act,  deed or  conveyance,  shall  become  vested with all the
          rights, powers, trusts and duties of the retiring Trustee with respect
          to the Securities of that or those series to which the  appointment of
          such successor Trustee relates;  but, on request of the Company or any
          successor Trustee,  such retiring Trustee shall duly assign,  transfer
          and deliver to such  successor  Trustee all property and money held by
          such retiring Trustee hereunder with respect to the Securities of that
          or those series to which the  appointment  of such  successor  Trustee
          relates.

               (3) Upon request of any such successor Trustee, the Company shall
          execute any and all instruments  for more fully and certainly  vesting
          in and  confirming to such successor  Trustee all such rights,  powers
          and trusts referred to in paragraph (a) or (b) of this Section, as the
          case may be.

               (4) No successor  Trustee shall accept its appointment  unless at
          the time of such acceptance such successor  Trustee shall be qualified
          and eligible under this Article.

               SECTION 610. Merger,  Conversion,  Consolidation or Succession to
          Business.  Any  corporation  into which the  Trustee  may be merged or
          converted  or with which it may be  consolidated,  or any  corporation
          resulting from any merger,  conversion or  consolidation  to which the
          Trustee  shall be a party,  or any  corporation  succeeding  to all or
          substantially  all of the  corporate  trust  business of the  Trustee,
          shall  be  the  successor  of the  Trustee  hereunder,  provided  such
          corporation  shall be  otherwise  qualified  and  eligible  under this
          Article,  without the  execution or filing of any paper or any further
          act on the part of any of the Parties  hereto.  In case any Securities
          or coupons shall have been  authenticated,  but not delivered,  by the
          Trustee  then in  office,  any  successor  by  merger,  conversion  or
          consolidation   to  such   authenticating   Trustee   may  adopt  such
          authentication  and deliver the Securities or coupons so authenticated
          with  the  same  effect  as  if  such  successor  Trustee  had  itself
          authenticated  such  Securities or coupons.  In case any Securities or
          coupons shall not have been authenticated by such predecessor Trustee,
          any  such  successor   Trustee  may   authenticate  and  deliver  such
          Securities  or  coupons,  in  either  its  own  name  or  that  of its
          predecessor  Trustee,  with the  full  force  and  effect  which  this
          Indenture  provides  for  the  certificate  of  authentication  of the
          Trustee.

               SECTION 611.  Appointment of  Authenticating  Agent. At ally time
          when any of the Securities remain Outstanding, the Trustee may appoint
          an  Authenticating  Agent or Agents with respect to one or more series
          of  Securities  which  shall be  authorized  to act on  behalf  of the
          Trustee  to  authenticate   Securities  of  such  series  issued  upon
          exchange,  registration of transfer or partial redemption or repayment
          thereof,  and  Securities  so  authenticated  shall be entitled to the
          benefits of this  Indenture and shall be valid and  obligatory for all
          purposes  as if  authenticated  by the  Trustee  hereunder.  Any  such
          appointment shall be evidenced by an instrument in writing signed by a
          Responsible  Officer of the Trustee,  a copy of which instrument shall
          be promptly  furnished to the Company.  Wherever  reference is made in
          this Indenture to the authentication and delivery of Securities by the
          Trustee or the Trustee's certificate of authentication, such reference
          shall be deemed to include  authentication  and  delivery on behalf of
          the  Trustee  by  an   Authenticating   Agent  and  a  certificate  of
          authentication  executed on behalf of the Trustee by an Authenticating
          Agent.  Each  Authenticating  Agent shall be acceptable to the Company
          and  shall  at all  times be a bank or trust  company  or  corporation
          organized and doing  business and in good  standing  wider the laws of
          the  United  States  of  America  or of any State or the  District  of
          Columbia,  authorized under such laws to act as Authenticating  Agent,
          having a combined capital and surplus of not less than $50,000,000 and
          subject to supervision or examination by Federal or State authorities.
          If such  Authenticating  Agent publishes reports of condition at least
          annually,  pursuant  to  law  or the  requirements  of  the  aforesaid
          supervising  or  examining  authority,  then for the  purposes of this
          Section, the combined capital and surplus of such Authenticating Agent
          shall be deemed to be its combined capital and surplus as set forth in
          its most recent report of condition so published.  In case at any time
          an Authenticating  Agent shall cease to be eligible in accordance with
          the provisions of this Section, such Authenticating Agent shall resign
          immediately  in the  manner  end with  the  effect  specified  in this
          Section.

     Any  corporation  into  which an  Authenticating  Agent  may be  merged  or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which such Authenticating Agent
shall be a party,  or any  corporation  succeeding  to the  corporate  agency or
corporate  trust business of an  Authenticating  Agent,  shall continue to be an
Authenticating  Agent,  provided such  corporation  shall be otherwise  eligible
under this Section,  without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent for any series of Securities may at any time resign
by giving  written  notice of  resignation to the Trustee for such series and to
the Company.  The Trustee for any series of Securities may at any time terminate
the agency of an Authenticating Agent by giving written notice of termination to
such  Authenticating  Agent and to the Company.  Upon receiving such a notice of
resignation  or  upon  such  a  termination,   or  in  case  at  any  time  such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  the Trustee for such series may appoint a successor
Authenticating  Agent  which shall be  acceptable  to the Company and shall give
notice of such  appointment  to all  Holders of  Securities  of the series  with
respect to which such Authenticating Agent will serve in the manner set forth in
Section  106.  Any  successor   Authenticating  Agent  upon  acceptance  of  its
appointment hereunder shall become vested with all the rights, powers and duties
of its  predecessor  hereunder,  with like effect as if  originally  named as an
Authenticating  Agent  herein.  No  successor   Authenticating  Agent  shall  be
appointed unless eligible under the provisions of this Section.

     The Company  agrees to pay to each  Authenticating  Agent from time to time
reasonable  compensation including  reimbursement of its reasonable expenses for
its services under this Section.

     If an  appointment  with respect to one or more series is made  pursuant to
this  Section,  the  Securities  of such series may have  endorsed  thereon,  in
addition  to or in lieu  of the  Trustee's  certificate  of  authentication,  an
alternate certificate of authentication substantially in the following form:

     This is one of the Securities of the series designated  therein referred to
in the within-mentioned Indenture.

               Sales,  Leases  and  Conveyances  Permitted  Subject  to  Certain
               Conditions.  The Company may consolidate  with, or sell, lease or
               convey all or  substantially  all of its assets to, or merge with
               or into any other  corporation,  provided  that in any such case,
               (1) either the Company shall be the  continuing  corporation,  or
               the successor  corporation  shall be a corporation  organized and
               existing  under the laws of the United  States or a State thereof
               and such successor corporation shall expressly assume the due and
               punctual  payment of the principal of (and  premium,  if any) and

               their tenor, and the due and punctual  performance and observance
               of all of the  covenants and  conditions of this  Indenture to be
               performed  by the Company by  supplemental  indenture,  complying
               with Article Nine hereof,  satisfactory to the Trustee,  executed

               immediately  after giving effect to such transaction and treating
               any  indebtedness  which  becomes an obligation of the Company or
               any Subsidiary as a result thereof as having been incurred by the
               Company or such  Subsidiary at the time of such  transaction,  no
               Event of Default,  and no event which,  after notice or the lapse
               of time,  or both,  would become an Event of Default,  shall have

               Company,  with the same effect as if it had been named  herein as
               the party of the first  part,  and the  predecessor  corporation,
               except in the event of a lease,  shall be relieved of any further
               obligation   under  this  Indenture  and  the  Securities.   Such
               successor  corporation  thereupon may cause to be signed, and may
               issue either in its own name or in the name of the  Company,  any
               or all of the Securities  issuable  hereunder  which  theretofore
               shall not have been signed by the Company  and  delivered  to the
               Trustee;  and,  upon  the  order of such  successor  corporation,
               instead of the Company, and subject to all the terms,  conditions
               and limitations in this Indenture  prescribed,  the Trustee shall
               authenticate  and shall deliver any Securities  which  previously
               shall  have been  signed and  delivered  by the  officers  of the
               Company to the Trustee  for  authentication,  and any  Securities
               which such  successor  corporation  thereafter  shall cause to be
               signed and  delivered  to the Trustee for that  purpose.  All the
               Securities  so issued shall in all  respects  have the same legal
               rank  and  benefit  under  this   Indenture  as  the   Securities
               theretofore or thereafter  issued in accordance with the terms of
               this  Indenture as though all of such  Securities had been issued
               at the date of the execution hereof.

     In case of any such consolidation,  merger, sale, lease or conveyance, such
changes  in  phraseology  and  form  (but not in  substance)  may be made in the
Securities thereafter to be issued as may be appropriate.

               SECTION 803.  Officers'  Certificate and Opinion of Counsel.  Any
          consolidation,  merger,  sale,  lease or  conveyance  permitted  under
          Section 801 is also subject to the condition that the Trustee  receive
          an Officers'  Certificate and an Opinion of Counsel to the effect that
          any such  consolidation,  merger,  sale, lease or conveyance,  and the
          assumption by any successor corporation,  complies with the provisions
          of this Article and that all conditions  precedent herein provided for
          relating to such transaction have been complied with.

               SECTION 901. Supplemental  Indentures without Consent of Holders.
          Without  the  consent of any Holders of  Securities  or  coupons,  the
          Company, when authorized by or pursuant to a Board Resolution, and the
          Trustee, at any time and from time to time, may enter into one or more
          indentures  supplemental  hereto, in form satisfactory to the Trustee,
          for any of the following purposes:

                    (1) to  evidence  the  succession  of another  Person to the

               of the Company herein and in the Securities contained;

                    (2) to add to the  covenants  of the Company for the benefit
               of the  Holders of all or any series of  Securities  (and if such
               covenants  are to be for the  benefit  of less than all series of
               Securities,  stating  that such  covenants  are  expressly  being
               included  solely for the benefit of such  series) or to surrender
               any right or power herein conferred upon the Company;

                    (3) to add any additional  Events of Default for the benefit
               of the  Holders of all or any series of  Securities  (and if such
               Events  of  Default  are to be for the  benefit  of less than all
               series of  Securities,  stating  that such  Events of Default are
               expressly  being included solely for the benefit of such series);
               provided,  however, that in respect of any such additional Events
               of  Default  such  supplemental   indenture  may  provide  for  a
               particular  period of grace after  default  (which  period may be
               shorter  or  longer  than  that  allowed  in the  case  of  other
               defaults) or may provide for an immediate  enforcement  upon such
               default or may limit the  remedies  available to the Trustee upon
               such  default or may limit the right of the Holders of a majority
               in  aggregate  principal  amount  of  that  or  those  series  of
               Securities  to which such  additional  Events of Default apply to
               waive such default;

                    (4) to add to or  change  any  of  the  provisions  of  this
               Indenture to provide that Bearer Securities may be registrable as
               to  principal,  to change or eliminate  any  restrictions  on the
               payment of  principal  of or any  premium or  interest  on Bearer
               Securities,  to permit Bearer Securities to be issued in exchange
               for  Registered  Securities,  to permit  Bearer  Securities to be
               issued in  exchange  for Bearer  Securities  of other  authorized
               denominations   or  to  permit  or  facilitate  the  issuance  of
               Securities in uncertificated  form, provided that any such action
               shall not  adversely  affect  the  interests  of the  Holders  of
               Securities  of any series or any related  coupons in any material
               respect;

                    (5) to change or  eliminate  any of the  provisions  of this
               Indenture,  provided  that any such change or  elimination  shall
               become  effective  only when there is no Security  Outstanding of
               any series  created prior to the  execution of such  supplemental
               indenture which is entitled to the benefit of such provisions;

                    (6) to secure the Securities;

                    (7) to  establish  the form or terms  of  Securities  of any
               series and any related  coupons as  permitted by Sections 201 and
               301,   including  the  provisions  and  procedures   relating  to
               Securities convertible into Common Shares or Preferred Shares, as
               the case may be;

                    (8)  to  evidence   and  provide  for  the   acceptance   of
               appointment  hereunder by a successor Trustee with respect to the
               Securities  of one or more  series and to add to or change any of
               the provisions of this Indenture as shall be necessary to provide
               for or facilitate the  administration  of the trusts hereunder by
               more than one Trustee;

                    (9) to cure any  ambiguity,  to  correct or  supplement  any
               provision herein which may be defective or inconsistent  with any
               other  provision  herein,  or to make any other  provisions  with
               respect to  matters or  questions  arising  under this  Indenture
               which  shall  not be  inconsistent  with the  provisions  of this
               Indenture,  provided such provisions  shall not adversely  affect
               the  interests of the Holders of  Securities of any series or any
               related coupons in any material respect; or

                    (10) to supplement  any of the  provisions of this Indenture
               to such extent as shall be necessary to permit or facilitate  the
               defeasance and discharge of any series of Securities  pursuant to
               Sections 401, 1402 and 1403;  provided that any such action shall
               not  adversely  affect the interests of the Holders of Securities
               of such  series and any  related  coupons or any other  series of
               Securities in any material respect.

               SECTION  902.  Supplemental  Indentures  with Consent of Holders.
          With the  consent  of the  Holders  of not  less  than a  majority  in
          principal  amount  of all  Outstanding  Securities  affected  by  such
          supplemental  indenture,  by  Act of  said  Holders  delivered  to the
          Company and the Trustee,  the Company,  when authorized by or pursuant
          to a Board Resolution,  and the Trustee may enter into an indenture or

          provisions  to or  changing  in any manner or  eliminating  any of the
          provisions of this  Indenture or of modifying in any manner the rights
          of the  Holders  of  Securities  and any  related  coupons  under this
          Indenture;  provided,  however,  that no such  supplemental  indenture
          shall,  without the consent of the Holder of each Outstanding Security
          affected thereby:

                    (1) change  the  Stated  Maturity  of the  principal  of (or
               premium,  if  any,  on) or any  installment  of  principal  of or
               interest on, any Security; or reduce the principal amount thereof
               or the rate or amount of interest  thereon or Additional  Amounts
               payable in  respect  thereof,  or any  premium  payable  upon the
               redemption  thereof,  or change any  obligation of the Company to
               pay  Additional  Amounts  pursuant  to  Section  1008  (except as
               contemplated by Section 801(1) and permitted by Section  901(1)),
               or  reduce  the  amount of the  principal  of an  Original  Issue
               Discount   Security   that  would  be  due  and  payable  upon  a
               declaration of acceleration of the Maturity  thereof  pursuant to
               Section 502 or the amount thereof provable in bankruptcy pursuant
               to Section 504, or adversely affect any right of repayment at the
               option of the  Holder  of any  Security,  or change  any Place of
               Payment where,  or the currency or  currencies,  currency unit or
               units or composite  currency or currencies in which, any Security
               or any premium or the interest thereon is payable,  or impair the
               right to institute  suit for the  enforcement of any such payment
               on or after  the  Stated  Maturity  thereof  (or,  in the case of
               redemption or repayment at the option of the Holder,  on or after
               the Redemption Date or the Repayment Date, as the case may be);

                    (2)  reduce  the  percentage  in  principal  amount  of  the
               Outstanding  Securities  of any  series,  the  consent  of  whose
               Holders is required for any such supplemental  indenture,  or the
               consent of whose  Holders is required for any waiver with respect
               to such series (or  compliance  with certain  provisions  of this
               Indenture or certain defaults  hereunder and their  consequences)
               provided for in this  Indenture,  or reduce the  requirements  of
               Section 1504 for quorum or voting; or

                    (3) modify any of the  provisions of this  Section,  Section
               513 or Section 1012,  except to increase the required  percentage
               to effect such action or to provide that certain other provisions
               of this  Indenture  cannot  be  modified  or waived  without  the
               consent  of the  Holder  of each  Outstanding  Security  affected
               thereby.

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

     A supplemental  indenture which changes or eliminates any covenant or other
provision of this  Indenture  which has expressly  been included  solely for the
benefit of one or more  particular  series of Securities,  or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other  provision,  shall be  deemed  not to  affect  the  rights  under  this
Indenture of the Holders of Securities of any other series.

               SECTION 903. Execution of Supplemental Indentures.  In executing,
          or  accepting  the  additional  trusts  created  by, any  supplemental
          indenture permitted by this Article or the modification thereby of the
          trusts  created by this  Indenture,  the Trustee  shall be entitled to
          receive,  and shall be fully  protected in relying upon, an Opinion of
          Counsel stating that the execution of such  supplemental  indenture is
          authorized or permitted by this Indenture.  The Trustee may, but shall
          not be obligated to, enter into any such supplemental  indenture which
          affects the  Trustee's  own rights,  duties or  immunities  under this
          Indenture or otherwise.

               SECTION  904.  Effect  of  Supplemental   Indentures.   Upon  the
          execution  of any  supplemental  indenture  under this  Article,  this
          Indenture  shall  be  modified  in  accordance  therewith,   and  such
          supplemental  indenture  shall form a part of this  Indenture  for all
          purposes;  and every Holder of  Securities  theretofore  or thereafter
          authenticated and delivered  hereunder and of any coupon  appertaining
          thereto shall be bound thereby.

               SECTION  905.   Conformity   with  Trust   Indenture  Act.  Every
          supplemental indenture executed pursuant to this Article shall conform
          to the requirements of the Trust Indenture Act as then in effect.

               SECTION 906. Reference in Securities to Supplemental  Indentures.
          Securities  of  any  series  authenticated  and  delivered  after  the
          execution of any supplemental  indenture pursuant to this Article may,
          and  shall,  if  required  by the  Trustee,  bear a  notation  in form
          approved  by  the  Trustee  as to any  matter  provided  for  in  such
          supplemental  indenture.  If  the  Company  shall  so  determine,  new
          Securities of any series so modified as to conform,  in the opinion of
          the Trustee and the Company, to any such supplemental indenture may be
          prepared and executed by the Company and  authenticated  and delivered
          by the Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE TEN

                                    COVENANTS

               SECTION 1001. Payment of Principal, Premium, if any, Interest and
          Additional  Amounts.  The Company covenants and agrees for the benefit
          of the  Holders  of each  series of  Securities  that it will duly and
          punctually pay the principal of (and premium,  if any) and interest on
          and any  Additional  Amounts  payable in respect of the  Securities of
          that series in accordance with the terms of such series of Securities,
          any coupons appertaining thereto and this Indenture.  Unless otherwise
          specified as contemplated by Section 301 with respect to any series of
          Securities,  any interest due on and any Additional Amounts payable in
          respect  of  Bearer  Securities  on or  before  Maturity,  other  than
          Additional  Amounts,  if any,  payable as provided in Section  1011 in
          respect of  principal  of (or  premium,  if any,  on) such a Security,
          shall be payable only upon  presentation  and surrender of the several
          coupons for such interest  installments  as are  evidenced  thereby as
          they  severally  mature.  Unless  otherwise  specified with respect to
          Securities of any series pursuant to Section 301, at the option of the
          Company,  all  payments  of  principal  may be  paid by  check  to the
          registered Holder of the Registered  Security or other person entitled
          thereto against surrender of such Security.  SECTION 1002. Maintenance
          of Office or Agency.  If  Securities  of a series are issuable only as
          Registered  Securities,  the Company  shall  maintain in each Place of
          Payment  for any  series of  Securities  an  office  or  agency  where
          Securities of that series may be presented or surrendered  for payment
          or conversion,  where Securities of that series may be surrendered for
          registration  of transfer or exchange and where notices and demands to
          or upon the  Company in respect of the  Securities  of that series and
          this  Indenture may be served.  If Securities of a series are issuable
          as Bearer Securities, the Company will maintain: (A) in the Borough of
          Manhattan,  New York City,  an office or agency  where any  Registered
          Securities of that series may be presented or surrendered  for payment
          or conversion,  where any Registered  Securities of that series may be
          surrendered  for  registration of transfer,  where  Securities of that
          series may be surrendered  for exchange,  where notices and demands to
          or upon the  Company in respect of the  Securities  of that series and
          this  Indenture  may be served  and where  Bearer  Securities  of that
          series and related coupons may be presented or surrendered for payment
          or  conversion  in  the  circumstances   described  in  the  following
          paragraph (and not otherwise);  (B) subject to any laws or regulations
          applicable  thereto,  in a Place of Payment for that  series  which is
          located  outside  the  United  States,   an  office  or  agency  where
          Securities  of that series and related  coupons may be  presented  and
          surrendered for payment  (including  payment of any Additional Amounts
          payable on  Securities  of that series  pursuant  to Section  1008) or
          conversion;  provided,  however, that if the Securities of that series
          are  listed  on the  Luxembourg  Stock  Exchange  or any  other  stock
          exchange  located  outside the United  States and such stock  exchange
          shall so require,  the Company  will  maintain a Paying  Agent for the
          Securities  of that series in  Luxembourg  or any other  required city
          located outside the United States,  as the case may be, so long as the
          Securities of that series are listed on such exchange; and (C) subject
          to any laws or regulations  applicable  thereto, in a Place of Payment
          for that series located  outside the United States an office or agency
          where any Registered  Securities of that series may be surrendered for
          registration  of  transfer,  where  Securities  of that  series may be
          surrendered  for exchange and where notices and demands to or upon the
          Company in respect of the Securities of that series and this Indenture
          may be served.  The  Company  will give prompt  written  notice to the
          Trustee of the location,  and any change in the location, of each such
          office or agency.  If at any time the  Company  shall fail to maintain
          any such  required  office  or  agency or shall  fail to  furnish  the
          Trustee  with the address  thereof,  such  presentations,  surrenders,
          notices  and  demands  may be made or  served at the  Corporate  Trust
          Office of the Trustee,  except that Bearer  Securities  of that series
          and the related  coupons may be presented and  surrendered for payment
          (including  payment  of  any  Additional  Amounts  payable  on  Bearer
          Securities  of that series  pursuant to Section 1008) or conversion at
          the offices  specified in the Security,  in London,  England,  and the
          Company  hereby  appoints  the  same  as its  agent  to  receive  such
          respective  presentations,  surrenders,  notices and demands,  and the
          Company  hereby  appoints  the  Trustee  its agent to receive all such
          presentations, surrenders, notices and demands.

     Unless  otherwise  specified  with  respect to any  Securities  pursuant to
Section  301, no payment of  principal,  premium or  interest  on or  Additional
Amounts in respect of Bearer Securities shall be made at any office or agency of
the Company in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States;  provided,  however,  that, if the Securities of a series are payable in
Dollars,  payment of  principal  of and any premium  and  interest on any Bearer
Security  (including any Additional Amounts payable on Securities of such series
pursuant to Section 1008) shall be made at the office of the designated agent of
the Company's  Paying Agent in the Borough of Manhattan,  New York City, if (but
only if)  payment  in  Dollars of the full  amount of such  principal,  premium,
interest or Additional  Amounts,  as the case may be, at all offices or agencies
outside  the  United  States  maintained  for  the  purpose  by the  Company  in
accordance with this Indenture,  is illegal or effectively precluded by exchange
controls or other similar restrictions.

     The Company may from time to time  designate  one or more other  offices or
agencies  where  the  Securities  of one or  more  series  may be  presented  or
surrendered  for any or all of such purposes,  and may from time to time rescind
such  designations;  provided,  however,  that no such designation or rescission
shall in any manner  relieve the Company of its obligation to maintain an office
or agency in accordance with the  requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such  designation or rescission and of any change in the location
of any such other office or agency.  Unless otherwise  specified with respect to
any  Securities  pursuant to Section 301 with respect to a series of Securities,
the  Company  hereby  designates  as a Place  of  Payment  for  each  series  of
Securities the office or agency of the Company in the Borough of Manhattan,  New
York City, and initially  appoints the Trustee at its Corporate  Trust Office as
Paying Agent and as its agent to receive all such presentations, surrenders, and
notices and demands.

     Unless  otherwise  specified  with  respect to any  Securities  pursuant to
Section 301, if and so long as the Securities of any series (i) are  denominated
in a Foreign Currency or (ii) may be payable in a Foreign  Currency,  or so long
as it is required under any other  provision of the Indenture,  then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

               SECTION 1003. Money for Securities  Payments to Be Held in Trust.
          If the  Company  shall at any time act as its own  Paying  Agent  with
          respect to any series of any  Securities and any related  coupons,  it
          will, on or before each due date of the principal of (and premium,  if
          any), or interest on or  Additional  Amounts in respect of, any of the
          Securities of that series, segregate and hold in trust for the benefit
          of the Persons  entitled there to a sum in the currency or currencies,
          currency  unit or units or composite  currency or  currencies in which
          the  Securities  of such  series  are  payable  (except  as  otherwise
          specified  pursuant to Section 301 for the  Securities of such series)
          sufficient to pay the principal  (and premium,  if any) or interest or
          Additional  Amounts so  becoming  due until such sums shall be paid to
          such Persons or  otherwise  disposed of as herein  provided,  and will
          promptly notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities  and any  related  coupons,  it  will,  before  each  due date of the
principal of (and  premium,  if any),  or interest on or  Additional  Amounts in
respect of, any Securities of that series, deposit with a Paying Agent a sum (in
the currency or  currencies,  currency  unit or units or  composite  currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium,  if any) or interest or Additional  Amounts, so becoming due, such
sum to be  held in  trust  for  the  benefit  of the  Persons  entitled  to such
principal,  premium or interest or  Additional  Amounts and (unless  such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

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

                    (1) hold all sums held by it for the payment of principal of
               (and  premium,  if any) or interest on  Securities  or Additional
               Amounts in trust for the benefit of the Persons  entitled thereto
               until  such  sums  shall  be paid to such  Persons  or  otherwise
               disposed of as herein provided;

                    (2) give the  Trustee  notice of any  default by the Company
               (or any other obligor upon the  Securities)  in the making of any
               such payment of principal  (and  premium,  if any) or interest or
               Additional Amounts; and

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

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those  upon  which  such sums were held by the  Company  or such
Paying Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such
Paying Agent shall be released from all further  Liability  with respect to such
sums.

     Except as otherwise  provided in the  Securities  of any series,  any money
deposited with the Trustee or any Paying Agent, or then held by the Company,  in
trust for the payment of the principal of (and premium,  if any) or interest on,
or any  Additional  Amounts  in  respect  of,  any  Security  of any  series and
remaining  unclaimed for two years after such principal  (and premium,  if any),
interest of Additional  Amounts have become due and payable shall be paid to the
Company  upon  Company  Request  or (if  then  held  by the  Company)  shall  be
discharged from such trust; and the Holder of such Security shall thereafter, as
an  unsecured  general  creditor,  look only to the  Company for payment of such
principal of (and premium,  if any) or interest on, or any Additional Amounts in
respect of, any Security,  without  interest  thereon,  and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee  thereof,  shall thereupon cease;  provided,  however,
that the Trustee or such Paying  Agent,  before being  required to make any such
repayment,  may at the expense of the Company cause to be published  once, in an
Authorized Newspaper, notice that such money remains unclaimed and that, after a
date  specified  therein,  which shall not be less than 30 days from the date of
such  publication,  any unclaimed  balance of such money then  remaining will be
repaid to the Company.

               SECTION 1004.  Existence.  Subject to Article Eight,  the Company
          will do or cause to be done all things  necessary to preserve and keep
          in full  force  and  effect  its  existence,  rights  and  franchises;
          provided,  however, that the Company shall not be required to preserve
          any right or franchise if the Board of Trust Managers shall  determine
          that the preservation thereof is no longer desirable in the conduct of
          the business of the Company.

               SECTION 1005. Payment of Taxes and Other Claims. The Company will
          pay or  discharge or cause to be paid or  discharged,  before the same
          shall become delinquent,  (1) all taxes,  assessments and governmental
          charges  levied  or  imposed  upon it or any  Subsidiary  or upon  the
          income, profits or property of the Company or any Subsidiary,  and (2)
          all lawful claims for labor,  materials and supplies which, if unpaid,
          might by law  become a lien upon the  property  of the  Company or any
          Subsidiary;  provided, however, that the Company shall not be required
          to pay or  discharge or cause to be paid or  discharged  any such tax,
          assessment, charge or claim whose amount, applicability or validity is
          being contested in good faith.

               SECTION 1006. Provision of Financial Information.  Whether or not
          the  Company  is  subject  to  Section  13 or 15(d) of the  Securities
          Exchange Act of 1934,  the Company  will  prepare the annual  reports,
          quarterly  reports and other  documents  within 15 days of each of the
          respective dates by which the Company would have been required to file
          with the Commission  pursuant to such Section 13 or 15(d) and will (i)
          transmit by mail to all Holders,  as their names and addresses  appear
          in the Security  Register,  without cost to such Holders copies of the
          annual  reports,  quarterly  reports  and  other  documents  which the
          Company would have been required to file with the Commission  pursuant
          to Section 13 or 15(d) of the  Securities  Exchange Act of 1934 if the
          Company  were  subject to such  Sections,  (ii) file with the  Trustee
          copies of the annual  reports,  quarterly  reports and other documents
          which the Company would have been required to file with the Commission
          pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934
          if the Company were subject to such  Sections and (iii)  promptly upon
          written  request and payment of the reasonable cost of duplication and
          delivery, supply copies of such documents to any prospective Holder.

               SECTION  1007.  Statement  as to  Compliance.  The  Company  will
          deliver to the  Trustee,  within 120 days after the end of each fiscal
          year,  a brief  certificate  from  the  principal  executive  officer,
          principal financial officer or principal  accounting officer as to his
          or her knowledge of the Company's  compliance  with all conditions and
          covenants under this Indenture and, in the event of any noncompliance,
          specifying such  noncompliance and the nature and status thereof.  For
          purposes of this Section  1010,  such  compliance  shall be determined
          without  regard to any period of grace or  requirement of notice under
          this Indenture.

               SECTION 1008.  Additional  Amounts. If any Securities of a series
          provide for the payment of Additional Amounts, the Company will pay to
          the Holder of any  Security of such series or any coupon  appertaining
          thereto  Additional  Amounts as may be  specified as  contemplated  by
          Section 301.  Whenever in this  Indenture  there is mentioned,  in any
          context  except in the case of  Section  502(1),  the  payment  of the
          principal  of or any  premium or  interest  on, or in respect  of, any
          Security  of any series or payment  of any  related  coupon or the net
          proceeds  received  on the sale or  exchange  of any  Security  of any
          series, such mention shall be deemed to include mention of the payment
          of Additional Amounts provided by the terms of such series established
          pursuant  to  Section  301  to  the  extent  that,  in  such  context,
          Additional  Amounts are,  were or would be payable in respect  thereof
          pursuant  to  such  terms  and  express  mention  of  the  payment  of
          Additional  Amounts (if applicable) in any provisions hereof shall not
          be  construed  as  excluding  Additional  Amounts in those  provisions
          hereof where such express mention is not made.

     Except as  otherwise  specified  as  contemplated  by Section  301,  if the
Securities of a series provide for the payment of Additional  Amounts,  at least
10 days prior to the first Interest  Payment Date with respect to that series of
Securities  (or if the Securities of that series will not bear interest prior to
Maturity,  the first day on which a payment  of  principal  and any  premium  is
made),  and at least 10 days prior to each date of payment of principal  and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Company will furnish the
Trustee and the Company's principal Paying Agent or Paying Agents, if other than
the Trustee,  with an  Officers'  Certificate  instructing  the Trustee and such
Paying  Agent or Paying  Agents  whether  such  payment of  principal of and any
premium or interest on the Securities of that series shall be made to Holders of
Securities  of that  series or any  related  coupons  who are not United  States
persons without  withholding  for or on account of any tax,  assessment or other
governmental  charge  described  in the  Securities  of the series.  If any such
withholding shall be required,  then such Officers' Certificate shall specify by
country the  amount,  if any,  required to be withheld on such  payments to such
Holders of Securities of that series or related coupons and the Company will pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms
of such  Securities.  In the event that the Trustee or any Paying Agent,  as the
case may be,  shall not so receive  the  above-mentioned  certificate,  then the
Trustee  or such  Paying  Agent  shall be  entitled  (i) to assume  that no such
withholding or deduction is required with respect to any payment of principal or
interest with respect to any Securities of a series or related  coupons until it
shall  have  received  a  certificate  advising  otherwise  and (ii) to make all
payments of principal and interest with respect to the Securities of a series or
related coupons without  withholding or deductions until otherwise advised.  The
Company covenants to indemnify the Trustee and any Paying Agent for, and to hold
them  harmless  against,  any loss,  liability  or expense  reasonably  incurred
without  negligence  or bad faith on their part arising out of or in  connection
with  actions  taken or omitted by any of them or in reliance  on any  Officers'
Certificate  furnished  pursuant to this Section or in reliance on the Company's
not furnishing such an Officers' Certificate.

               SECTION 1009. Waiver of Certain  Covenants.  The Company may omit
          in any  particular  instance  to comply  with any term,  provision  or
          condition set forth in Sections 1004 to 1009, inclusive,  if before or
          after the time for such  compliance the Holders of at least a majority
          in principal amount of all outstanding  Securities of such series,  by
          Act of such Holders,  either waive such compliance in such instance or
          generally  waive  compliance  with such covenant or condition,  but no
          such  waiver  shall  extend to or affect such  covenant  or  condition
          except to the extent so expressly waived, and, until such waiver shall
          become effective, the obligations of the Company and the duties of the
          Trustee  in respect of any such term,  provision  or  condition  shall
          remain in full force and effect.


                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

               SECTION 1101. Applicability of Article.  Securities of any series
          which are redeemable  before their Stated Maturity shall be redeemable
          in accordance  with their terms and (except as otherwise  specified as
          contemplated   by  Section  301  for  Securities  of  any  series)  in
          accordance with this Article.

               SECTION 1102. Election to Redeem; Notice to Trustee. The election
          of the  Company  to redeem any  Securities  shall be  evidenced  by or
          pursuant  to a Board  Resolution.  In case  of any  redemption  at the
          election  of the  Company  of less than all of the  Securities  of any
          series, the Company shall, at least 45 days prior to the giving of the
          notice of redemption in Section 1104 (unless a shorter notice shall be
          satisfactory  to the  Trustee),  notify the Trustee in writing of such
          Redemption  Date and of the  principal  amount of  Securities  of such
          series to be redeemed.  In the case of any  redemption  of  Securities
          prior to the expiration of any restriction on such redemption provided
          in the terms of such  Securities or elsewhere in this  Indenture,  the
          Company  shall  furnish the  Trustee  with all  Officers'  Certificate
          evidencing compliance with such restriction.

               SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.
          If less than all the  Securities  of any series issued on the same day
          with the same terms are to be redeemed,  the particular  Securities to
          be  redeemed  shall be  selected  not more  than 60 days  prior to the
          Redemption  Date by the Trustee,  from the  Outstanding  Securities of
          such  series  issued on such date with the same  terms not  previously
          called for  redemption,  by such method as the Trustee shall deem fair
          and  appropriate and which may provide for the election for redemption
          of  portions  (equal  to  the  minimum  authorized   denomination  for
          Securities  of that series or any  integral  multiple  thereof) of the
          principal amount of Securities of such series of a denomination larger
          than  the  minimum  authorized  denomination  for  Securities  of that
          series.

     The Trustee shall  promptly  notify the Company and the Security  Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any  Securities  selected for partial  redemption,  the principal
amount thereof to be redeemed.

     For all purposes of this Indenture,  unless the context otherwise requires,
all  provisions  relating to the redemption of Securities  shall relate,  in the
case of any Security  redeemed or to be redeemed only in part, to the portion of
the principal amount of such Security which has been or is to be redeemed.

               SECTION 1104. Notice of Redemption. Notice of redemption shall be
          given in the manner provided in Section 106, not less than 30 days nor
          more  than 60 days  prior to the  Redemption  Date,  unless a  shorter
          period is specified by the terms of such series  established  pursuant
          to Section  301,  to each Holder of  Securities  to be  redeemed,  but
          failure  to give such  notice in the  manner  herein  provided  to the
          Holder of any  Security  designated  for  redemption  as a whole or in
          part, or any defect in the notice to any such Holder, shall not affect
          the validity of the  proceedings  for the redemption of any other such
          Security or portion thereof.

     Any notice that is mailed to the Holders of  Registered  Securities  in the
manner herein provided shall be  conclusively  presumed to have been duly given,
whether or not the Holder receives the notice.

          All notices of redemption shall state:

               (1) the Redemption Date;

               (2) the Redemption Price, accrued interest to the Redemption Date
          payable as provided in Section 1106, if any, and  Additional  Amounts,
          if any;

               (3) if less than all Outstanding  Securities of any series are to
          be  redeemed,   the  identification  (and,  in  the  case  of  partial
          redemption,  the  principal  amount)  of the  particular  Security  or
          Securities to be redeemed;

               (4) in case any  Security  is to be  redeemed  in part only,  the
          notice which  relates to such  Security  shall state that on and after
          the Redemption Date, upon surrender of such Security,  the holder will
          receive,  without a charge, a new Security or Securities of authorized
          denominations for the principal amount thereof remaining unredeemed;

               (5) that on the Redemption Date the Redemption  Price and accrued
          interest to the  Redemption  Date payable as provided in Section 1106,
          if any,  will become due and payable upon each such  Security,  or the
          Portion  thereof,  to be redeemed  and, if  applicable,  that interest
          thereon shall cease to accrue on and after said date;

               (6) the  Place  or  Places  of  Payment  where  such  Securities,
          together   in  the  case  of  Bearer   Securities   with  all  coupons
          appertaining  thereto, if any, maturing after the Redemption Date, are
          to be  surrendered  for  payment of the  Redemption  Price and accrued
          interest, if any, or for conversion;

               (7) that the  redemption  is for a sinking  fund,  if such is the
          case;

               (8) that,  unless  otherwise  specified  in such  notice,  Bearer
          Securities of any series,  if any,  surrendered for redemption must be
          accompanied by all coupons  maturing  subsequent to the date fixed for
          redemption or the amount of any such missing coupon or coupons will be
          deducted  from the  Redemption  Price,  unless  security or  indemnity
          satisfactory  to the  Company,  the  Trustee  for such  series and any
          Paying Agent is furnished;

               (9) if Bearer Securities of any series are to be redeemed and any
          Registered  Securities  of such series are not to be redeemed,  and if
          such Bearer Securities may be exchanged for Registered  Securities not
          subject to redemption on this  Redemption Date pursuant to Section 305
          or otherwise,  the last date,  as determined by the Company,  on which
          such exchanges may be made;

               (10) the CUSIP number of such Security, if any, and

               (11) if  applicable,  that a Holder of Securities  who desires to
          convert  Securities for redemption must satisfy the  requirements  for
          conversion contained in such Securities,  the then existing conversion
          price or rate,  and the date and time when the option to convert shall
          expire.

     Notice of redemption  of  Securities  to be redeemed  shall be given by the
Company  or, at the  Company's  request,  by the  Trustee in the name and at the
expense of the Company.

               SECTION 1105.  Deposit of  Redemption  Price.  On any  Redemption
          Date,  the  Company  shall  deposit  with the Trustee or with a Paying
          Agent (or, if the Company is acting as its own Paying Agent,  which it
          may not do in the case of a sinking fund payment under Article Twelve,
          segregate  and hold in trust as provided in Section 1003) an amount of
          money  in the  currency  or  currencies,  currency  unit or  units  or
          composite  currency  or  currencies  in which the  Securities  of such
          series are payable (except as otherwise  specified pursuant to Section
          301  for  the  Securities  of such  series)  sufficient  to pay on the
          Redemption Date the Redemption Price of, and (except if the Redemption
          Date shall be an Interest  Payment Date) accrued  interest on, all the
          Securities or portions thereof which are to be redeemed on that date.

               SECTION 1106.  Securities  Payable on Redemption Date.  Notice of
          redemption  having been given as  aforesaid,  the  Securities so to be
          redeemed shall, on the Redemption Date,  become due and payable at the
          Redemption  Price  therein  specified in the  currency or  currencies,
          currency  unit or units or composite  currency or  currencies in which
          the  Securities  of such  series  are  payable  (except  is  otherwise
          specified  pursuant to Section 301 for the  Securities of such series)
          (together with accrued interest,  if any, to the Redemption Date), and
          from and after such date  (unless  the  Company  shall  default in the
          payment of the Redemption Price and accrued  interest) such Securities
          shall, if the same were  interest-bearing,  cease to heir interest and
          the coupons for such interest appertaining to any Bearer Securities so
          to be redeemed,  except to the extent provided  below,  shall be void.
          Upon surrender of any such Security for redemption in accordance  with
          said notice,  together with all coupons, if any,  appertaining thereto
          maturing after the Redemption Date, such Security shall be paid by the
          Company at the Redemption Price,  together with accrued  interest,  if
          any, to the Redemption Date; provided,  however,  that installments of
          interest on Bearer  Securities whose Stated Maturity is on or prior to
          the  Redemption  Date  shall be  payable  only at an  office or agency
          located  outside the United  States  (except as otherwise  provided in
          Section  1002) and,  unless  otherwise  specified as  contemplated  by
          Section 301, only upon  presentation and surrender of coupons for such
          interest; and provided further that, except as otherwise provided with
          respect to  Securities  convertible  into Common  Shares or  Preferred
          Shares, installments of interest on Registered Securities whose Stated
          Maturity is on or prior to the Redemption Date shall be payable to the
          Holders of such  Securities,  or one or more  Predecessor  Securities,
          registered  as such at the close of  business on the  relevant  Record
          Dates according to their terms and the provisions of Section 307.

     If any Bearer Security  surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after  deducting from the  Redemption  Price an amount equal to the face
amount of all such missing  coupons,  or the surrender of such missing coupon or
coupons may be waived by the Company  and the Trustee if there be  furnished  to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption  Price,  such Holder shall be
entitled to receive the amount so deducted;  provided,  however,  that  interest
represented  by  coupons  shall be payable  only at an office or agency  located
outside the United  States  (except as otherwise  provided in Section 1002) and,
unless   otherwise   specified  as   contemplated  by  Section  301,  only  upon
presentation and surrender of those coupons.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for redemption,  the principal (and premium,  if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Security.

               SECTION  1107.   Securities  Redeemed  in  Part.  Any  Registered
          Security  which  is to be  redeemed  only  in  part  (pursuant  to the
          provisions of this Article or of Article  Twelve) shall be surrendered
          at a Place of Payment therefor (with, if the Company or the Trustee so
          requires,  due endorsement by, or a written  instrument of transfer in
          form satisfactory to the Company and the Trustee duly executed by, the
          Holder  thereof or his attorney  duly  authorized  in writing) and the
          Company shall execute and the Trustee shall  authenticate  and deliver
          to the Holder of such Security  without  service charge a new Security
          or Securities of the same series,  of any authorized  denomination  as
          requested by such Holder in aggregate principal amount equal to and in
          exchange for the  unredeemed  portion of the principal of the Security
          so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

               SECTION 1201.  Applicability  of Article.  The provisions of this
          Article shall be applicable to any sinking fund for the  retirement of
          Securities of a series except as otherwise  specified as  contemplated
          by Section 301 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities  of any series is herein  referred to as a  "mandatory  sinking  fund
payment",  and any payment in excess of such minimum amount  provided for by the
terms of such  Securities  of any series is herein  referred to as an  "optional
sinking fund  payment".  It provided for by the terms of any  Securities  of any
series,  the cash amount of any mandatory sinking fund payment may be subject to
reduction  as provided in Section  1202.  Each  sinking  fund  payment  shall be
applied to the  redemption  of  Securities  of any series as provided for by the
terms of Securities of such series.

               SECTION  1202.   Satisfaction   of  Sinking  Fund  Payments  with
          Securities. The Company may, in satisfaction of all or any part of any
          mandatory  sinking fund payment  with respect to the  Securities  of a
          series, (1) deliver Outstanding  Securities of such series (other than
          any  previously  called for  redemption)  together  in the case of any
          Bearer   Securities  of  such  series  with  all   unmatured   coupons
          appertaining  thereto  and (2)  apply as a credit  Securities  of such
          series which have been redeemed  either at the election of the Company
          pursuant to the terms of such Securities or through the application of
          permitted optional sinking fund payments pursuant to the terms of such
          Securities,  as provided for by the terms of such Securities, or which
          have  otherwise  been  acquired  by the  Company;  provided  that such
          Securities  so  delivered  or  applied  as  a  credit  have  not  been
          previously so credited. Such Securities shall be received and credited
          for such  purpose by the Trustee at the  applicable  Redemption  Price
          specified in such Securities for redemption  through  operation of the
          sinking  fund and the amount of such  mandatory  sinking  fund payment
          shall be reduced accordingly.

               SECTION 1203. Redemption of Securities for Sinking Fund. Not less
          than 60 days prior to each sinking fund payment date for Securities of
          any series,  the  Company  will  deliver to the  Trustee in  Officers'
          Certificate  specifying  the  amount  of the  next  ensuing  mandatory
          sinking  fund  payment for that  series  pursuant to the terms of that
          series,  the portion  thereof,  if any,  which is to be  satisfied  by
          payment of cash in the currency or currencies,  currency unit or units
          or composite  currency or currencies  in which the  Securities of such
          series are payable (except as otherwise  specified pursuant to Section
          301 for the  Securities  of such series) and the portion  thereof,  if
          any, which is to be satisfied by delivering  and crediting  Securities
          of that series pursuant to Section 1202, and the optional  amount,  if
          any, to be added in cash to the next  ensuing  mandatory  sinking fund
          payment,  and will also deliver to the Trustee any Securities to be so
          delivered and credited. If such Officers' Certificate shall specify an
          optional  amount  to be added in cash to the  next  ensuing  mandatory
          sinking fund payment,  the Company shall thereupon be obligated to pay
          the amount therein  specified.  Not less than 30 days before each such
          sinking fund payment date the Trustee  shall select the  Securities to
          be  redeemed  upon  such  sinking  fund  payment  date  in the  manner
          specified in Section 1103 and cause notice of the  redemption  thereof
          to be given in the name of and at the  expense  of the  Company in the
          manner  provided in Section 1104.  Such notice having been duly given,
          the redemption of such Securities  shall be made upon the terms and in
          the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

               SECTION 1301.  Applicability of Article.  Repayment of Securities
          of any series  before their  Stated  Maturity at the option of Holders
          thereof shall be made in accordance with the terms of such Securities,
          if any, and (except as otherwise specified by the terms of such series
          established pursuant to Section 301) in accordance with this Article.

               SECTION 1302.  Repayment of Securities.  Securities of any series
          subject to  repayment in whole or in part it the option of the Holders
          thereof  will,  unless  otherwise   provided  in  the  terms  of  such
          Securities,  be  repaid  at a  price  equal  to the  principal  amount
          thereof,  together  with  interest,  if any,  thereon  accrued  to the
          Repayment  Date  specified  in  or  pursuant  to  the  terms  of  such
          Securities. The Company covenants that at least one Business Day prior
          to the  Repayment  Date it will  deposit  with the  Trustee  or with a
          Paying  Agent (or, if the  Company is acting as its own Paying  Agent,
          segregate  and hold in trust as provided in Section 1003) an amount of
          money  in the  currency  or  currencies,  currency  unit or  units  or
          composite  currency  or  currencies  in which the  Securities  of such
          series are payable (except as otherwise  specified pursuant to Section
          301 for the Securities of such series) sufficient to pay the principal
          (or, if so provided by the terms of the  Securities  of any series,  a
          percentage of the  principal)  of, and (except if the  Repayment  Date
          shall be in  Interest  Payment  Date)  accrued  interest  on,  all the
          Securities  or portions  thereof,  as the case may be, to be repaid on
          such date.

               SECTION  1303.  Exercise  of  Option.  Securities  of any  series
          subject to repayment at the option of the Holders thereof will contain
          an "Option to Elect Repayment" form on the reverse of such Securities.
          In order for any  Security  to be repaid at the option of the  Holder,
          the Trustee must receive at the Place of Payment therefor specified in
          the terms of such  Security (or at such other place or places of which
          the  Company  shall  from  time to time  notify  the  Holders  of such
          Securities)  not earlier  than 60 days nor later than 30 days prior to
          the Repayment  Date (1) the Security so providing  for such  repayment

          setting  forth the name of the Holder of the  Security,  the principal
          amount of the  Security,  the  principal  amount of the Security to be
          repaid,  the CUSIP number,  if any, or a description  of the tenor and
          terms of the Security,  a statement that the option to elect repayment
          is being  exercised  thereby and a guarantee  that the  Security to be
          repaid,  together with the duly  completed  form  entitled  "Option to
          Elect  Repayment" on the reverse of the Security,  will be received by
          the  Trustee not later than the fifth  Business  Day after the date of
          such telegram,  telex,  facsimile  transmission  or letter;  provided,
          however, that such telegram,  telex,  facsimile transmission or letter
          shall only be effective if such  Security and form duly  completed are
          received by the Trustee by such fifth  Business  Day. If less than the
          entire principal amount of such Security is to be repaid in accordance
          with the terms of such Security, the principal amount of such Security
          to be repaid, in increments of the minimum denomination for Securities
          of such series,  and the denomination or denominations of the Security
          or  Securities  to be  issued to the  Holder  for the  portion  of the
          principal  amount  of  such  Security  surrendered  that  is not to be
          repaid,  must be  specified.  The  principal  amount  of any  Security
          providing for  repayment,  at the option of the Holder thereof may not
          be repaid in part if,  following such repayment,  the unpaid principal
          amount  of such  Security  would be less than the  minimum  authorized
          denomination  of Securities of the series of which such Security to be
          repaid is a part.  Except as otherwise may be provided by the terms of
          any  Security  providing  for  repayment  at the  option of the Holder
          thereof,  exercise  of the  repayment  option by the  Holder  shall be
          irrevocable unless waived by the Company.

               SECTION 1304. When Securities  Presented for Repayment Become Due
          and Payable.  If Securities  of any series  providing for repayment at
          the  option of the  Holders  thereof  shall have been  surrendered  as
          provided  in this  Article and as provided by or pursuant to the terms
          of such Securities,  such Securities or the portions  thereof,  as the
          case may be, to be repaid  shall  become due and  payable and shall be
          paid by the Company on the Repayment  Date therein  specified,  and on
          and after such Repayment Date (unless the Company shall default in the
          payment of such  Securities on such  Repayment  Date) such  Securities
          shall, if the same were  interest-bearing,  cease to bear interest and
          the coupons for such interest appertaining to any Bearer Securities so
          to be repaid, except to the extent provided below, shall be void. Upon
          surrender of any such Security for  repayment in accordance  with such
          provisions,  together with all coupons, if any,  appertaining  thereto
          maturing  after  the  Repayment  Date,  the  principal  amount of such
          Security so to be repaid shall be paid by the Company,  together  with
          accrued interest,  if any, to the Repayment Date;  provided,  however,
          that  coupons  whose Stated  Maturity is on or prior to the  Repayment
          Date shall be payable only at an office or agency located  outside the
          United  States  (except as  otherwise  provided in Section  1002) and,
          unless  otherwise   specified  pursuant  to  Section  301,  only  upon
          presentation and surrender of such coupons; and provided further that,
          in the case of Registered  Securities,  installments  of interest,  if
          any, whose Stated  Maturity is on or prior to the Repayment Date shall
          be payable (but without  interest  thereon,  unless the Company  shall
          default in the payment thereof) to the Holders of such Securities,  or
          one or more Predecessor Securities, registered as such at the close of
          business on the relevant Record Dates according to their terms and the
          provisions of Section 307.

     If any Bearer  Security  surrendered for repayment shall not be accompanied
by all appurtenant  coupons maturing after the Repayment Date, such Security may
be paid after deducting from the amount payable  therefor as provided in Section
1302 an amount  equal to the face  amount of all such  missing  coupons,  or the
surrender of such missing coupon or coupons may be waived by the Company and the
Trustee if there be  furnished  to them such  security or  indemnity as they may
require to save each of them and any Paying Agent  harmless.  If thereafter  the
Holder of such Security  shall  surrender to the Trustee or any Paying Agent any
such  missing  coupon in  respect of which a  deduction  shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted;  provided,  however,  that interest  represented  by coupons
shall be payable only at an office or agency  located  outside the United States
(except as otherwise  provided in Section 1002) and, unless otherwise  specified
as  contemplated by Section 301, only upon  presentation  and surrender of those
coupons. If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender  thereof,  such principal  amount (together with
interest,  if any,  thereon accrued to such Repayment  Date) shall,  until paid,
bear  interest  from  the  Repayment  Date at the rate of  interest  or Yield to
Maturity (in the case of Original Issue Discount  Securities)  set forth in such
Security.

               SECTION 1305.  Securities  Repaid in Part.  Upon surrender of any
          Registered  Security  which is to be repaid in part only,  the Company
          shall  execute and the Trustee shall  authenticate  and deliver to the
          Holder of such Security,  without service charge and at the expense of
          the  Company,  a new  Registered  Security or  Securities  of the same
          series, of any authorized  denomination specified by the Holder, in an
          aggregate principal amount equal to and in exchange for the portion of
          the  principal  of such  Security  so  surrendered  which is not to be
          repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

               SECTION  1401.  Applicability  of  Article;  Company's  Option to
          Effect Defeasance or Covenant Defeasance. If, pursuant to Section 301,
          provision  is  made  for  either  or  both  of (a)  defeasance  of the
          Securities  of or within a series  under  Section 1402 or (b) covenant
          defeasance of the Securities of or within a series under Section 1403,
          then the  provisions of such Section or Sections,  as the case may be,
          together  with  the  other  provisions  of  this  Article  (with  such
          modifications thereto as may be specified pursuant to Section 301 with
          respect to any Securities), shall be applicable to such Securities and
          any coupons appertaining thereto, and the Company may at its option by
          Board Resolution, at any time, with respect to such Securities and any
          coupons  appertaining   thereto,   elect  to  have  Section  1402  (if
          applicable)  or  Section  1403  (if  applicable)  be  applied  to such
          Outstanding  Securities  and any  coupons  appertaining  thereto  upon
          compliance with the conditions set forth below in this Article.

               SECTION  1402.  Defeasance  and  Discharge.  Upon  the  Company's
          exercise of the above option  applicable  to this Section with respect
          to any  Securities of or within a series,  the Company shall be deemed
          to have been  discharged  from its  obligations  with  respect to such
          Outstanding  Securities  and any coupons  appertaining  thereto on the
          date  the   conditions   set  forth  in  Section  1404  are  satisfied
          (hereinafter,  "defeasance").  For this purpose, such defeasance means
          that the  Company  shall be  deemed to have  paid and  discharged  the
          entire indebtedness represented by such Outstanding Securities and any
          coupons appertaining  thereto,  which shall thereafter be deemed to be
          "Outstanding"  only for the  purposes  of  Section  1405 and the other
          Sections of this  Indenture  referred to in clauses (A) and (B) below,
          and to  have  satisfied  all  of  its  other  obligations  under  such
          Securities  and any coupons  appertaining  thereto and this  Indenture
          insofar as such  Securities and any coupons  appertaining  thereto are
          concerned  (and the  Trustee,  at the  expense of the  Company,  shall
          execute proper  instruments  acknowledging  the same),  except for the
          following which shall survive until otherwise terminated or discharged
          hereunder:  (A) the rights of Holders of such  Outstanding  Securities
          and any coupons appertaining thereto to receive, solely from the trust
          fund  described  in  Section  1404 and as more fully set forth in such
          Section, payments in respect of the principal of (and premium, if any)
          and interest,  if any, on such Securities and any coupons appertaining
          thereto when such payments are due, (B) the Company's obligations with
          respect to such Securities  under Sections 305, 306, 1002 and 1003 and
          with  respect to the payment of  Additional  Amounts,  if any, on such
          Securities as  contemplated  by Section 1011, (C) the rights,  powers,
          trusts,  duties and  immunities of the Trustee  hereunder and (D) this
          Article. Subject to compliance with this Article Fourteen, the Company
          may exercise its option under this Section  notwithstanding  the prior
          exercise  of its  option  under  Section  1403  with  respect  to such
          Securities and any coupons appertaining thereto.

               SECTION 1403. Covenant Defeasance. Upon the Company's exercise of
          the above  option  applicable  to this  Section  with  respect  to any
          Securities  of or within a series,  the Company shall be released from
          its  obligations  under  Sections  1004 to 1009,  inclusive,  and,  if
          specified  pursuant to Section  301, its  obligations  under any other
          covenant,  with respect to such Outstanding Securities and any coupons
          appertaining thereto on and after the date the conditions set forth in
          Section 1404 are satisfied (hereinafter,  "covenant defeasance"),  and
          such Securities and any coupons  appertaining thereto shall thereafter
          be deemed to be not  "Outstanding"  for the purposes of any direction,
          waiver, consent or declaration or Act of Holders (and the consequences
          of any thereof) in connection  with Sections 1004 to 1009,  inclusive,
          or such other covenant,  but shall continue to be deemed "Outstanding"
          for all other  purposes  hereunder.  For this  purpose,  such covenant
          defeasance means that, with respect to such Outstanding Securities and
          any coupons appertaining  thereto, the Company may omit to comply with
          and shall  have no  liability  in respect  of any term,  condition  or
          limitations  set forth in any such  Section  or such  other  covenant,
          whether directly or indirectly,  by reason of any reference  elsewhere
          herein to any such  Section  or such  other  covenant  or by reason of
          reference  in any such  Section  or such other  covenant  to any other
          provision  herein or in any other document and such omission to comply
          shall not  constitute a default or an Event of Default  under  Section
          501(4) or  501(8) or  otherwise,  as the case may be,  but,  except as
          specified  above,  the remainder of this Indenture and such Securities
          and any coupons appertaining thereto shall be unaffected thereby.

               SECTION 1404.  Conditions  to Defeasance or Covenant  Defeasance.
          The following  shall be the  conditions to application of Section 1402
          or Section 1403 to any  Outstanding  Securities  of or within a series
          and any coupons appertaining thereto:

                    (1) The Company shall  irrevocably  have deposited or caused
               to be deposited with the Trustee (or another  trustee  satisfying
               the  requirements  o(pound) Section 608 who shall agree to comply
               with the provisions of this Article Fourteen applicable to it) as
               trust  funds in trust for the  purpose  of making  the  following
               payments,  specifically  pledged as security  for, and  dedicated
               solely to, the benefit of the Holders of such  Securities and any
               coupons  appertaining  thereto,  (A) an amount in such  currency,
               currencies  or  currency  unit in which such  Securities  and any
               coupons  appertaining  thereto are then  specified  as payable at
               Stated Maturity, or (B) Government Obligations applicable to such
               Securities and coupons  appertaining  thereto  (determined on the
               basis of the currency,  currencies or currency unit in which such
               Securities and coupons appertaining thereto are then specified as
               payable at Stated  Maturity) which through the scheduled  payment
               of principal and interest in respect  thereof in accordance  with
               their terms will  provide,  not later than one day before the due
               date of any payment of  principal  of (and  premium,  if any) and
               interest, if any, on such Securities and any coupons appertaining
               thereto, money in an amount, or (C) a combination thereof, in any
               case,  in an amount,  sufficient,  without  consideration  of any
               reinvestment of such principal and interest,  in the opinion of a
               nationally  recognized  firm of  independent  public  accountants
               expressed  in a written  certification  thereof  delivered to the
               Trustee, to pay and discharge,  and which shall be applied by the
               Trustee (or other qualifying  trustee) to pay and discharge,  (i)
               the principal of (and premium,  if any) and interest,  if any, on
               such Outstanding  Securities and any coupons appertaining thereto
               on the  Stated  Maturity  of such  principal  or  installment  of
               principal  or  interest  and  (ii)  any  mandatory  sinking  fund
               payments or analogous  payments  applicable  to such  Outstanding
               Securities  and any  coupons  appertaining  thereto on the day on
               which such  payments are due and payable in  accordance  with the
               terms of this  Indenture and of such  Securities  and any coupons
               appertaining thereto;

                    (2) Such defeasance or covenant  defeasance shall not result
               in a breach or violation of, or constitute a default under,  this
               Indenture or any other material  agreement or instrument to which
               the Company is a party or by which it is bound;

                    (3) No Event of Default or event  which with notice or lapse
               of time or both would  become an Event of Default with respect to
               such Securities and any coupons  appertaining  thereto shall have
               occurred  and be  continuing  on the  date  of such  deposit  or,
               insofar as Sections 501(6) and 501(7) are concerned,  at any time
               during the  period  ending on the 91st day after the date of such
               deposit (it being  understood  that this  condition  shall not be
               deemed satisfied until the expiration of such period);

                    (4) In the  case of an  election  under  Section  1402,  the
               Company shall have delivered to the Trustee an Opinion of Counsel
               stating that (i) the Company has received from, or there has been
               published  by, the  Internal  Revenue  Service a ruling,  or (ii)
               since the date of execution of this  Indenture,  there has been a
               change in the  applicable  Federal income tax law, in either case
               to the effect that,  and based thereon such opinion shall confirm
               that, the Holder of such  Outstanding  Securities and any coupons
               appertaining  thereto will not recognize income, gain or loss for
               Federal  income tax purposes as a result of such  defeasance  and
               will be subject to Federal income tax on the same amounts, in the
               same  manner and at the same times as would have been the case if
               such defeasance had not occurred;

                    (5) In the  case of an  election  under  Section  1403,  the
               Company shall have delivered to the Trustee an Opinion of Counsel
               to the effect that the Holders of such Outstanding Securities and
               any coupons  appertaining thereto will not recognize income, gain
               or loss for  Federal  income  tax  purposes  as a result  of such
               covenant  defeasance and will be subject to Federal income tax on
               the same  amounts,  in the same  manner  and at the same times as
               would  have  been the case if such  covenant  defeasance  had not
               occurred;

                    (6) The  Company  shall  have  delivered  to the  Trustee an
               Officers'  Certificate  and an Opinion of Counsel,  each  stating
               that all  conditions  precedent to the  defeasance  under Section
               1402 or the covenant  defeasance  under Section 1403 (as the case
               may be) have been  complied with and an Opinion of Counsel to the
               effect  that  either  (i) as a result  of a deposit  pursuant  to
               subsection  (a) above and the related  exercise of the  Company's
               option  under  Section 1402 or Section 1403 (as the case may be),
               registration is not required under the Investment  Company Act of
               1940, as amended, by the Company, with respect to the trust funds
               representing  such deposit or by the Trustee for such trust funds
               or (ii) all  necessary  registrations  under  said Act have  been
               effected; and

                    (7)  Notwithstanding  any other  provisions of this Section,
               such  defeasance  or  covenant  defeasance  shall be  effected in
               compliance with any additional or substitute terms, conditions or
               limitations  which may be  imposed on the  Company in  connection
               therewith pursuant to Section 301;

               SECTION 1405.  Deposited  Money and Government  Obligations to Be
          Held  in  Trust;  Other  Miscellaneous  Provisions.   Subject  to  the
          provisions  of the last  paragraph  of  Section  1003,  all  money and
          Government  Obligations (or other property as may be provided pursuant
          to Section 301)  (including the proceeds  thereof)  deposited with the
          Trustee (or other  qualifying  trustee,  collectively  for purposes of
          this Section 1405, the "Trustee")  pursuant to Section 1404 in respect
          of  any   Outstanding   Securities  of  any  series  and  any  coupons
          appertaining  thereto  shall  be  held in  trust  and  applied  by the
          Trustee,  in accordance with the provisions of such Securities and any
          coupons  appertaining  thereto  and this  Indenture,  to the  payment,
          either  directly or through any Paying  Agent  (including  the Company
          acting as its own Paying Agent) as the Trustee may  determine,  to the
          Holders of such Securities and any coupons appertaining thereto of all
          sums due and to become  due  thereon  in  respect  of  principal  (and
          premium, if any) and interest and Additional Amounts, if any, but such
          money need not be  segregated  from other  funds  except to the extent
          required by law.

     Unless otherwise specified with respect to any Security pursuant to Section
301, if, after a deposit  referred to in Section  1404(a) has been made, (a) the
Holder of a Security in respect of which such  deposit was made is entitled  to,
and does, elect pursuant to Section 301 or the terms of such Security to receive
payment  in a currency  or  currency  unit other than that in which the  deposit
pursuant to Section 1404(a) has been made in respect, of such Security, or (b) a
Conversion Event occurs in respect of the currency or currency unit in which the
deposit pursuant to Section 1404(a) his been made, the indebtedness  represented
by such  Security and any coupons  appertaining  thereto shall be deemed to have
been,  and will be, fully  discharged  and satisfied  through the payment of the
principal of (and premium,  if any),  and interest,  if any, on such Security as
the same becomes due out of the  proceeds  yielded by  converting  (from time to
time as specified  below in the case of any such  election)  the amount or other
property  deposited  in respect of such  Security  into the currency or currency
unit in which such  Security  becomes  payable as a result of such  election  or
Conversion Event based on the applicable  market exchange rate for such currency
or  currency  unit in effect on the second  Business  Day prior to each  payment
date, except,  with respect to a Conversion Event, for such currency or currency
unit in effect (as nearly as feasible) at the time of the Conversion Event.

     The Company  shall pay and  indemnify  the Trustee  against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited
pursuant  to Section  1404 or the  principal  and  interest  received in respect
thereof  other than any such tax,  fee or other  charge  which by law is for the
account  of  the  Holders  of  such  Outstanding   Securities  and  any  coupons
appertaining thereto.

     Anything  in this  Article  to the  contrary  notwithstanding,  subject  to
Section 607, the Trustee  shall  deliver or pay to the Company from time to time
upon Company Request any money or Government  Obligations (or other property and
any proceeds  therefrom)  held by it as provided in Section  1404 which,  in the
opinion  of a  nationally  recognized  firm of  independent  public  accountants
expressed in a written  certification  thereof delivered to the Trustee,  are in
excess of the amount  thereof  which would then be required to be  deposited  to
effect a defeasance or covenant  defeasance,  as applicable,  in accordance with
this Article.

                                 ARTICLE FIFTEEN

                        MEETINGS OF HOLDERS OF SECURITIES

               Section.

               SECTION  1503.  Persons  Entitled  to  Vote  at  Meetings.  To be
          entitled  to vote at any  meeting  of  Holders  of  Securities  of any
          series,  a Person  shall be (1) a  Holder  of one or more  Outstanding
          Securities of such series,  or (2) a Person appointed by an instrument
          in writing as proxy for a Holder or Holders of one or more Outstanding
          Securities of such series by such Holder or Holders.  The only Persons
          who shall be  entitled  to be  present  or to speak at any  meeting of
          Holders of Securities  of any series shall be the Persons  entitled to
          vote at such meeting and their  counsel,  any  representatives  of the
          Trustee and its counsel and any representatives of the Company and its
          counsel.

               SECTION  1504.  Quorum;  Action.  The Persons  entitled to vote a
          majority in principal amount of the Outstanding Securities of a series
          shall  constitute a quorum for a meeting of Holders of  Securities  of
          such series;  provided,  however, that if any action is to be taken at
          such meeting with respect to a consent or waiver which this  Indenture
          expressly  provides  may be given by the  Holders  of not less  than a
          specified percentage in principal amount of the Outstanding Securities
          of a series, the Persons entitled to vote such specified percentage in
          principal  amount of the  Outstanding  Securities of such series shall
          constitute  a quorum.  In the  absence  of a quorum  within 30 minutes
          after the time appointed for any such meeting,  the meeting shall,  if
          convened at the request of Holders of  Securities  of such series,  be
          dissolved. In any other case the meeting may be adjourned for a period
          of not less than 10 days as  determined by the chairman of the meeting
          prior to the  adjournment of such meeting.  In the absence of a quorum
          at the  reconvening  of any such  adjourned  meeting,  such  adjourned
          meeting  may be  further  adjourned  for a period  of not less than 10
          days; at the reconvening of any meeting adjourned or further adjourned
          for  lack  of a  quorum,  the  persons  entitled  to  vote  25% in the
          aggregate  principal  amount of the Securities at the time outstanding
          shall  constitute  a quorum  for the taking of any action set forth in
          the notice of the original  meeting.  Notice of the reconvening of any
          adjourned  meeting  shall be given as  provided  in  Section  1502(a),
          except  that such  notice  need be given  only once not less than five
          days  prior  to the date on  which  the  meeting  is  scheduled  to be
          reconvened.

     Except as limited by the proviso to Section 902, any  resolution  presented
to a meeting or adjourned  meeting duly  reconvened at which a quorum is present
as aforesaid may be adopted by the affirmative  vote of the persons  entitled to
vote a majority in  aggregate  principal  amount of the  Outstanding  Securities
represented at such meeting;  provided,  however, that, except as limited by the
proviso to Section 902,  any  resolution  with  respect to any request,  demand,
authorization,  direction,  notice,  consent,  waiver or other action which this
Indenture  expressly  provides  may be made,  given or taken by the Holders of a
specified percentage,  which is less than a majority, in principal amount of the
Outstanding  Securities  of a series may be adopted at a meeting or an adjourned
meeting  duly  reconvened  and at which a quorum is present as  aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of that series.

     Any  resolution  passed or  decision  taken at any  meeting  of  Holders of
Securities  of any series duly held in  accordance  with this  Section  shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

         Notwithstanding  the foregoing  provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
     respect to any request, demand, authorization,  direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified  percentage  in  principal  amount of all
Outstanding  Securities  affected thereby,  or of the Holders of such series and
one or more additional series:

                    (i) there shall be no minimum  quorum  requirement  for such
               meeting; and

                    (ii) the principal  amount of the Outstanding  Securities of
               such  series  that  vote  in  favor  of  such  request,   demand,
               authorization, direction, notice, consent, waiver or other action
               shall be taken into account in determining  whether such request,
               demand,  authorization,  direction,  notice,  consent,  waiver or
               other action has been made, given or taken under this Indenture.

               SECTION  1505.   Determination  of  Voting  Rights;  Conduct  and
          Adjournment of Meetings.  (1)  Notwithstanding  any provisions of this
          Indenture,  the Trustee may make such reasonable regulations as it may
          deem advisable for any meeting of Holders of Securities of a series in
          regard to proof of the holding of Securities of such series and of the
          appointment of proxies and in regard to the  appointment and duties of
          inspectors  of votes,  the  submission  and  examination  of  proxies,
          certificates  and other  evidence of the right to vote, and such other
          matters  concerning  the  conduct  of the  meeting  as it  shall  deem
          appropriate.  Except as  otherwise  permitted  or required by any such
          regulations,  the holding of Securities  shall be proved in the manner
          specified  in Section  104 and the  appointment  of any proxy shall be
          proved  in the  manner  specified  in  Section  104 or by  having  the
          signature of the Person executing the proxy witnessed or guaranteed by
          any trust company, bank or banker authorized by Section 104 to certify
          to the holding of Bearer Securities. Such regulations may provide that
          written instruments appointing proxies,  regular on their face, may be
          presumed valid and genuine  without the proof specified in Section 104
          or other proof.

                    (2) The Trustee shall, by an instrument in writing appoint a
               temporary chairman of the meeting,  unless the meeting shall have
               been  called  by the  Company  or by  Holders  of  Securities  as
               provided  in Section  1502(2),  in which case the  Company or the
               Holders of Securities of the series  calling the meeting,  as the
               case may be, shall in like manner appoint a temporary chairman. A
               permanent chairman and a permanent secretary of the meeting shall
               be elected by vote of the Persons  entitled to vote a majority in
               principal  amount of the  Outstanding  Securities  of such series
               represented at the meeting.

                    (3) At any meeting  each Holder of a Security of such series
               or proxy shall be entitled to one vote for each $1,000  principal
               amount  of the  Outstanding  Securities  of such  series  held or
               represented by him; provided, however, that no vote shall be cast
               or counted at any meeting in respect of any  Security  challenged
               as not Outstanding and ruled by the chairman of the meeting to be
               not Outstanding.  The chairman of the meeting shall have no right
               to vote,  except  as a Holder  of a  Security  of such  series or
               proxy.

                    (4) Any meeting of Holders of  Securities of any series duly
               called  pursuant to Section 1502 at which a quorum is present may
               be  adjourned  from time to time by  Persons  entitled  to vote a
               majority in principal  amount of the  Outstanding  Securities  of
               such series  represented  at the meeting,  and the meeting may be
               held as so adjourned without further notice.

               SECTION 1506.  Counting  Votes and Recording  Action of Meetings.
          The vote upon any  resolution  submitted  to any meeting of Holders of
          Securities of any series shall be by written ballots on which shall be
          subscribed  the signatures of the Holders of Securities of such series
          or of their  representatives  by proxy and the  principal  amounts and
          serial  numbers of the  Outstanding  Securities of such series held or
          represented  by them.  The  permanent  chairman of the  meeting  shall
          appoint two  inspectors of votes who shall count all votes cast at the
          meeting for or against any resolution and who shall make and file with
          the  secretary  of the  meeting  their  verified  written  reports  in
          duplicate  of all votes  cast at the  meeting.  A record,  at least in
          duplicate, of the proceedings of each meeting of Holders of Securities
          of any Series  shall be prepared by the  secretary  of the meeting and
          there shall be attached  to said  record the  original  reports of the
          inspectors of votes on any vote by ballot taken thereat and affidavits
          by one or more persons having  knowledge of the fact,  setting forth a
          copy of the notice of the  meeting  and  showing  that said notice was
          given as provided in Section 1502 and, if  applicable,  Section  1504.
          Each copy  shall be  signed  and  verified  by the  affidavits  of the
          permanent  chairman  and  secretary  of the  meeting and one such copy
          shall be  delivered  to the  Company  and another to the Trustee to be
          preserved  by the  Trustee,  the latter to have  attached  thereto the
          ballots voted at the meeting.  Any record so signed and verified shall
          be conclusive evidence of the matters therein stated.

     This Indenture may be executed in any number of counterparts, each of which
so executed shall be deemed to be an original,  but all such counterparts  shall
together constitute but one and the same Indenture.

          SECTION  102.   Compliance   Certificates   and  Opinions.   Upon  any
     application  or  request by the  Company to the  Trustee to take any action
     under any  provision of this  Indenture,  the Company  shall furnish to the
     Trustee an Officers' Certificate stating that all conditions precedent,  if
     any,  provided for in this Indenture  relating to the proposed  action have
     been complied with and an Opinion of Counsel stating that in the opinion of
     such counsel all such  conditions  precedent,  if any,  have been  complied
     with,  except  that in the case of any such  application  or  request as to
     which the  furnishing  of such  documents is  specifically  required by any
     provision of this  Indenture  relating to such  particular  application  or
     request, no additional certificate or opinion need be furnished.

     Every certificate or opinion with respect to compliance with a condition or
covenant  provided  for in  this  Indenture  (including  certificates  delivered
pursuant to Section 1010) shall include:

                  (1) a statement that each individual  signing such certificate

          examination  or  investigation  upon which the  statements or opinions
          contained in such certificate or opinion are based;

          such condition or covenant has been complied with; and

               (4) a  statement  as to  whether,  in the  opinion  of each  such

          SECTION 103. Form of Documents Delivered to Trustee. In any case where
     several  matters are required to be certified  by, or covered by an opinion
     of, any  specified  Person,  it is not  necessary  that all such matters be
     certified  by, or covered by the opinion of, only one such Person,  or that
     they be so certified or covered by only one  document,  but one such Person
     may  certify or give an opinion  as to some  matters  and one or more other
     such Persons as to other  matters,  and any such Person may certify or give
     an opinion as to such matters in one or several documents.

     Any  certificate  or opinion of an  officer  of the  Company  may be based,
insofar as it  relates  to legal  matters,  upon an  Opinion  of  Counsel,  or a
certificate or representations by counsel,  unless such officer knows, or in the
exercise of  reasonable  care should  know,  that the  opinion,  certificate  or
representations  with  respect  to the  matters  upon which his  certificate  or
opinion is based are  erroneous.  Any such Opinion of Counsel or  certificate or
representations may be based,  insofar as it relates to factual matters,  upon a
certificate or opinion of, or representations  by, an officer or officers of the
Company  stating  that the  information  as to such  factual  matters  is in the
possession  of the Company,  unless such counsel knows that the  certificate  or
opinion or representations as to such matters are erroneous.

     Where  any  Person  is  required  to  make,  give  or  execute  two or more
applications,  requests, consents,  certificates,  statements, opinions or other
instruments  under this Indenture,  they may, but need not, be consolidated  and
form one instrument.

          SECTION 104. Acts of Holders. (1) Any request, demand,  authorization,
     direction,  notice,  consent,  waiver  or  other  action  provided  by this
     Indenture to be given or taken by Holders of the Outstanding  Securities of
     all series or one or more  series,  as the case may be, may be  embodied in
     and evidenced by one or more  instruments  of  substantially  similar tenor
     signed by such Holders in person or by agents duly appointed in writing. If
     Securities  of a series are  issuable as Bearer  Securities,  any  request,
     demand,  authorization,  direction, notice, consent, waiver or other action
     provided by this Indenture to be given or taken by Holders of Securities of
     such series may, alternatively,  be embodied in and evidenced by the record
     of Holders of Securities of such series voting in favor thereof,  either in
     person or by proxies duly  appointed in writing,  at any meeting of Holders
     of Securities  of such series duly called and held in  accordance  with the
     provisions of Article Fifteen, or a combination of such instruments and any
     such record.  Except as herein otherwise  expressly  provided,  such action
     shall become  effective  when such  instrument or  instruments or record or
     both  are  delivered  to the  Trustee  and,  where it is  hereby  expressly
     required,  to the Company.  Such  instrument  or  instruments  and any such
     record (and the action embodied  therein and evidenced  thereby) are herein
     sometimes  referred to as the "Act" of the Holders  signing such instrument
     or instruments or so voting at any such meeting.  Proof of execution of any
     such  instrument  or of a  writing  appointing  any such  agent,  or of the
     holding by any Person of a Security, shall be sufficient for any purpose of
     this Indenture. The record of any meeting of Holders of Securities shall be
     proved in the manner provided in Section 1506.

               (2) The fact and date of the  execution by any Person of any such
          instrument  or writing may be proved by the  affidavit of a witness of
          such execution or by a certificate of a notary public or other officer
          authorized by law to take  acknowledgments  of deeds,  certifying that
          the individual signing such instrument or writing  acknowledged to him
          the execution thereof. Where such execution is by a signer acting in a
          capacity  other than his  individual  capacity,  such  certificate  or
          affidavit shall also constitute sufficient proof of his authority. The
          fact and date of the execution of any such  instrument or writing,  or
          the authority of the Person  executing the same, may also be proved in
          any other reasonable manner which the Trustee deems sufficient.

               (3) The ownership of Registered Securities shall be proved by the
          Security Register.

               (4) The  ownership  of  Bearer  Securities  may be  proved by the
          production of such Bearer Securities or by a certificate  executed, as
          depositary,  by any trust company,  bank,  banker or other depositary,
          wherever situated,  if such certificate shall be deemed by the Trustee
          to be  satisfactory,  showing that at the date therein  mentioned such
          Person had on deposit  with such  depositary,  or exhibited to it, the
          Bearer Securities  therein  described;  or such facts may be proved by
          the  certificate  or  affidavit  of the  Person  holding  such  Bearer
          Securities,  if such certificate or affidavit is deemed by the Trustee
          to be  satisfactory.  The Trustee and the Company may assume that such
          ownership  of  any  Bearer   Security   continues  until  (1)  another
          certificate or affidavit bearing a later date issued in respect of the
          same Bearer  Security  is  produced,  or (2) such  Bearer  Security is
          produced  to the  Trustee by some  other  Person,  or (3) such  Bearer
          Security is surrendered in exchange for a Registered Security,  or (4)
          such Bearer Security is no longer Outstanding. The ownership of Bearer
          Securities  may also be proved in any other  manner  which the Trustee
          deems sufficient.

               (5) If the Company  shall  solicit from the Holders of Registered
          Securities  any request,  demand,  authorization,  direction,  notice,
          consent,  waiver or other Act, the Company  may, at its option,  in or
          pursuant to a Board  Resolution,  fix in advance a record date for the
          determination  of  Holders  entitled  to give  such  request,  demand,
          authorization,  direction,  notice,  consent, waiver or other Act, but
          the Company  shall have no obligation  to do so.  Notwithstanding  TIA
          Section 316(c), such record date shall be the record date specified in
          or  pursuant  to such  Board  Resolution,  which  shall  be a date not
          earlier  than the  date 30 days  prior to the  first  solicitation  of
          Holders generally in connection  therewith and not later than the date
          such  solicitation is completed.  If such a record date is fixed, such
          request, demand, authorization,  direction, notice, consent, waiver or
          other Act may be given before or after such record date,  but only the
          Holders of record at the close of  business  on such record date shall
          be  deemed to be  Holders  for the  purposes  of  determining  whether
          Holders of the requisite  proportion of  Outstanding  Securities  have
          authorized   or  agreed  or   consented  to  such   request,   demand,
          authorization,  direction,  notice,  consent, waiver or other Act, and
          for that purpose the  Outstanding  Securities  shall be computed as of
          such record date;  provided that no such  authorization,  agreement or
          consent by the Holders on such  record date shall be deemed  effective
          unless it shall become  effective  pursuant to the  provisions of this
          Indenture not later than eleven months after the record date.

     In the absence of any such record date fixed by the Company,  regardless as
to whether a  solicitation  of the Holders is occurring on behalf of the Company
or any Holder,  the Trustee may, at its option, fix in advance a record date for
the  determination  of such  Holders  entitled  to give  such  request,  demand,
authorization,  direction, notice, consent, waiver or other Act, but the Trustee
shall have no obligation to do so. Any such record date shall be a date not more
than 30 days prior to the first  solicitation of Holders generally in connection
therewith no later than the date of such solicitation.

               (6)  Any  request,  demand,  authorization,   direction,  notice,
          consent,  waiver or other Act of the Holder of any Security shall bind
          every  future  Holder  of the same  Security  and the  Holder of every
          Security  issued  upon the  registration  of  transfer  thereof  or in
          exchange  therefor  or in lieu  thereof in respect of  anything  done,
          omitted or suffered to be done by the Trustee, any Security Registrar,
          any Paying Agent, any Authenticating  Agent or the Company in reliance
          thereon,  whether  or not  notation  of such  action is made upon such
          Security.

               SECTION 105. Notices,  etc., to Trustee and Company. Any request,
          demand,  authorization,  direction,  notice, consent, waiver or Act of
          Holders or other  document  provided or permitted by this Indenture to
          be made upon, given or furnished to, or filed with,

               (1)  the  Trustee  by any  Holder  or by  the  Company  shall  be
          sufficient for every purpose  hereunder if made,  given,  furnished or
          filed in writing to or with the Trustee at 600 Travis,  Houston, Texas
          77002; or

               (2)  the  Company  by the  Trustee  or by  any  Holder  shall  be
         sufficient  for  every  purpose   hereunder  (unless  otherwise  herein
         expressly  provided)  if in writing  and mailed,  first  class  postage
         prepaid, to the Company addressed to it at the address of its principal
         office  specified in the first  paragraph  of this  Indenture or at any
         other  address  previously  furnished  in writing to the Trustee by the
         Company.

               SECTION  106.  Notice to Holders;  Waiver.  Where this  Indenture
          provides for notice of any event to Holders of  Registered  Securities
          by the Company or the Trustee, such notice shall be sufficiently given
          (unless otherwise herein expressly provided) if in writing and mailed,
          first-class  postage  prepaid,  to each such  Holder  affected by such
          event,  at his  address as it appears in the  Security  Register,  not
          later than the latest date,  and not earlier  than the earliest  date,
          prescribed for the giving of such notice.  In any case where notice to
          Holders of Registered Securities is given by mail, neither the failure
          to mail such  notice,  nor any defect in any notice so mailed,  to any
          particular  Holder  shall affect the  sufficiency  of such notice with
          respect to other Holders of Registered  Securities or the  sufficiency
          of any  notice to  Holders  of  Bearer  Securities  given as  provided
          herein.  Any notice mailed to a Holder in the manner herein prescribed
          shall be  conclusively  deemed to have been  received by such  Holder,
          whether or not such Holder actually receives such notice.

     If by reason of the suspension of or irregularities in regular mail service
or by reason of any other cause it shall be impracticable to give such notice by
mail,  then such  notification  to Holders of Registered  Securities as shall be
made with the approval of the Trustee shall constitute a sufficient notification
to such Holders for every purpose hereunder.

     Except as otherwise  expressly provided herein or otherwise  specified with
respect to any Securities pursuant to Section 301, where this Indenture provides
for notice to Holders of Bearer  Securities  of any event,  such notice shall be
sufficiently given if published in an Authorized  Newspaper in New York City and
in such  other  city or  cities  as may be  specified  in such  Securities  on a
Business Day,  such  publication  to be not later than the latest date,  and not
earlier than the earliest date,  prescribed  for the giving of such notice.  Any
such notice  shall be deemed to have been given on the date of such  publication
or, if published more than once, on the date of the first such publication.

     If by reason of the suspension of  publication of any Authorized  Newspaper
or  Authorized  Newspapers  or  by  reason  of  any  other  cause  it  shall  be
impracticable to publish any notice to Holders of Bearer  Securities as provided
above,  then such notification to Holders of Bearer Securities as shall be given
with the  approval of the Trustee  shall  constitute  sufficient  notice to such
Holders  for every  purpose  hereunder.  Neither  the  failure to give notice by
publication to any particular Holder of Bearer Securities as provided above, nor
any defect in any notice so  published,  shall  affect the  sufficiency  of such
notice with respect to other Holders of Bearer  Securities or the sufficiency of
any notice to Holders of Registered  Securities  given as provided  herein.  Any
request, demand, authorization, direction, notice, consent or waiver required or
permitted under this Indenture shall be in the English language, except that any
published notice may be in an official language of the country of publication.

     Where this Indenture provides for notice in any manner,  such notice may be
waived in writing by the Person  entitled to receive such notice,  either before
or after the event,  and such waiver  shall be the  equivalent  of such  notice.
Waivers of notice by Holders  shall be filed with the  Trustee,  but such filing
shall not be a  condition  precedent  to the  validity  of any  action  taken in
reliance upon such waiver.

               SECTION  107.  Effect  of  Headings  and Table of  Contents.  The
          Article and Section  headings herein and the Table of Contents are for
          convenience only and shall not affect the construction hereof.

               SECTION 108. Successors and Assigns. All covenants and agreements
          in this  Indenture  by the  Company  shall  bind  its  successors  and
          assigns, whether so expressed or not.

               SECTION 109.  Severability  Clause. In case any provision in this
          Indenture or in any  Security or coupon  shall be invalid,  illegal or
          unenforceable,  the  validity,  legality  and  enforceability  of  the
          remaining  provisions  shall not in any way be  affected  or  impaired
          thereby.

               SECTION 110. Benefits of Indenture.  Nothing in this Indenture or
          in the  Securities or coupons,  express or implied,  shall give to any
          Person,  other than the parties hereto,  any Security  Registrar,  any
          Paying Agent, any Authenticating  Agent and their successors hereunder
          and the Holders any benefit or any legal or equitable right, remedy or
          claim under this Indenture.

               SECTION 111. Governing Law. This Indenture and the Securities and
          coupons shall be governed by and construed in accordance  with the law
          of the State of New York.  This Indenture is subject to the provisions
          of the TIA that are required to be part of this  Indenture  and shall,
          to the extent applicable, be governed by such provisions.

               SECTION  112.  Legal  Holidays.  In any case  where any  Interest
          Payment Date,  Redemption Date,  Repayment Date,  sinking fund payment
          date,  Stated  Maturity  or Maturity  of any  Security  shall not be a
          Business Day at any Place of Payment,  then (notwithstanding any other
          provision  of this  Indenture  or any  Security or coupon other than a
          provision in the  Securities of any series which  specifically  states
          that such provision  shall apply in lieu hereof),  payment of interest
          or any Additional Amounts or principal (and premium,  if any) need not
          be made at such Place of Payment on such date,  but may be made on the
          next  succeeding  Business  Day at such Place of Payment with the same
          force and effect as if made on the Interest  Payment Date,  Redemption
          Date,  Repayment  Date or sinking fund payment  date, or at the Stated
          Maturity or Maturity,  provided  that no interest  shall accrue on the
          amount so payable for the period from and after such Interest  Payment
          Date,  Redemption  Date,  Repayment  Date,  sinking fund payment date,
          Stated Maturity or Maturity, as the case may be.

               SECTION 113. Immunity of Shareholders,  Trust Managers,  Officers
          and Agents of the Company.  In accordance  with Article Fifteen of the
          Amended and Restated Declaration of Trust of the Company ("Declaration
          of Trust"),  the Trustee recognizes and agrees that the obligations of
          the Company under the Indenture and the  Securities  and all documents
          delivered  in the  name of the  Company  in  connection  herewith  and
          therewith do not and shall not constitute personal  obligations of the
          Trust  Managers,  officers,  employees,  agents or shareholders of the
          Company or any of them,  and shall not  involve  any claim  against or
          personal  liability  on the part of any of them,  and that all persons
          including  the Trustee  shall look solely to the assets of the Company
          for the payment of any claim thereunder or for the performance thereof
          and shall not seek  recourse  against such Trust  Managers,  officers,
          employees, agents or shareholders of the Company or any of them or any
          of their personal assets for such satisfaction. The performance of the
          obligations  of the Company under the Indenture and the Securities and
          all  documents  delivered  in the name of the  Company  in  connection
          therewith  shall not be deemed a waiver of any rights or powers of the
          Company,  Trust  Managers or  shareholders  under the  Declaration  of
          Trust.

                                   ARTICLE TWO

                                SECURITIES FORMS

               SECTION 201. Forms of Securities.  The Registered Securities,  if
          any, of each series and the Bearer Securities,  if any, of each series
          and related  coupons shall be in  substantially  the forms as shall be
          established in one or more indentures  supplemental hereto or approved
          from time to time by or pursuant to a Board  Resolution  in accordance
          with Section 301, shall have such appropriate  insertions,  omissions,
          substitutions  and other  variations  as are  required or permitted by
          this Indenture or any indenture supplemental hereto, and may have such
          letters,  numbers or other marks of  identification or designation and
          such legends or  endorsements  placed  thereon as the Company may deem
          appropriate  and as are not  inconsistent  with the provisions of this
          Indenture,  or as may be  required  to comply with any law or with any
          rule  or  regulation  made  pursuant  thereto  or  with  any  rule  or
          regulation  of any  stock  exchange  on which  the  Securities  may be
          listed, or to conform to usage.

     Unless   otherwise   specified  as  contemplated  by  Section  301,  Bearer
Securities shall have interest coupons attached.

     The  definitive  Securities and coupons shall be printed,  lithographed  or
engraved or produced by any  combination  of these  methods on a steel  engraved
border or steel engraved borders or may be produced in any other manner,  all as
determined by the officers executing such Securities or coupons, as evidenced by
their execution of such Securities or coupons.

               SECTION 202.  Form of Trustee's  Certificate  of  Authentication.
          Subject to Section 611, the Trustee's  certificate  of  authentication
          shall be in substantially the following form:

     This is one of the Securities of the series designated  therein referred to
in the within-mentioned Indenture.

                            _________________________________, as Trustee

                   By:      __________________________________
                                   Authorized Signatory

               SECTION 203. Securities Issuable in Global Form. If Securities of
          or within a series  are  issuable  in global  form,  as  specified  as
          contemplated  by  Section  301,  then,  notwithstanding  clause (8) of
          Section 301 and the provisions of Section 302, any such Security shall
          represent such of the  Outstanding  Securities of such series as shall
          be  specified  therein and may  provide  that it shall  represent  the
          aggregate amount of Outstanding Securities of such series from time to
          time  endorsed  thereon and that the aggregate  amount of  Outstanding
          Securities of such series represented thereby may from time to time be
          increased or  decreased to reflect  exchanges.  Any  endorsement  of a
          Security  in global form to reflect  the  amount,  or any  increase or
          decrease in the amount, of Outstanding  Securities represented thereby
          shall be made by the  Trustee  in such  manner  and upon  instructions
          given by such  Person or Persons as shall be  specified  therein or in
          the Company  Order to be delivered to the Trustee  pursuant to Section
          303  or  304.  Subject  to the  provisions  of  Section  303  and,  if
          applicable,  Section 304, the Trustee  shall deliver and redeliver any
          Security in permanent global form in the manner and upon  instructions
          given by the Person or Persons  specified therein or in the applicable
          Company  Order.  If a Company Order pursuant to Section 303 or 304 has
          been, or simultaneously is, delivered, any instructions by the Company
          with respect to endorsement or delivery or redelivery of a Security in
          global form shall be in writing  but need not comply with  Section 102
          and need not be accompanied by an Opinion of Counsel.

     The  provisions  of the last  sentence  of Section  303 shall  apply to any
Security  represented  by a Security in global form if such  Security  was never
issued and sold by the  Company  and the  Company  delivers  to the  Trustee the
Security in global  form  together  with  written  instructions  (which need not
comply with  Section 102 and need not be  accompanied  by an Opinion of Counsel)
with regard to the reduction in the principal  amount of Securities  represented
thereby,  together with the written statement  contemplated by the last sentence
of Section 303.

     Notwithstanding  the provisions of Section 307, unless otherwise  specified
as  contemplated  by Section  301,  payment of  principal of and any premium and
interest on any Security in permanent global form shall be made to the Person or
Persons specified therein.

     Notwithstanding the provisions of Section 308 and except as provided in the
preceding  paragraph,  the Company, the Trustee and any agent of the Company and
the Trustee shall treat as the Holder of such  principal  amount of  Outstanding
Securities  represented  by a  permanent  global  Security  (i) in the case of a
permanent  global  Security in  registered  form,  the Holder of such  permanent
global  Security in registered  form, or (ii) in the case of a permanent  global
Security in bearer form, Euroclear or CEDEL.

          payable or in which the Securities of the series shall be denominated;

               (12) whether the amount of payments of principal of (and premium,
          if any) or interest,  if any, on the  Securities  of the series may be
          determined with reference to an index,  formula or other method (which
          index, formula or method may be based,  without limitation,  on one or
          more currencies,  currency units,  composite currencies,  commodities,
          equity indices or other indices), and the manner in which such amounts
          shall be determined;

          terms and  conditions  upon which,  such election may be made, and the
          time and manner  of,  and  identity  of the  exchange  rate agent with
          responsibility for, determining the exchange rate between the currency

          be specified;

               (15) any  deletions  from,  modifications  of or additions to the
          Events  of  Default  or  covenants  of the  Company  with  respect  to

          vice versa (if permitted by applicable laws and regulations),  whether
          any Securities of the series are to be issuable initially in temporary
          global  form  and  whether  any  Securities  of the  series  are to be
          issuable in permanent  global form with or without coupons and, if so,
          whether  beneficial  owners of interests in any such permanent  global
          Security may exchange such interests for Securities of such series and
          of  like  tenor  of any  authorized  form  and  denomination  and  the

          the close of business on the  Regular  Record Date for such  interest,
          the manner in which, or the Person to whom, any interest on any Bearer
          Security  of the  series  shall be  payable,  if  otherwise  than upon
          presentation and surrender of the coupons appertaining thereto as they
          severally mature, and the extent to which, or the manner in which, any
          interest payable on a temporary global Security on an Interest Payment
          Date will be paid if other than in the manner provided in Section 304;

               (19) the  applicability,  if any, of Sections 1402 and/or 1403 to
          the Securities of the series and any provisions in modification of, in
          addition to or in lieu of any of the provisions of Article Fourteen;

               (20) if the  Securities  of such  series  are to be  issuable  in
          definitive  form (whether  upon  original  issue or upon exchange of a
          temporary  Security  of such  series)  only upon  receipt  of  certain
          certificates or other  documents or satisfaction of other  conditions,
          then  the  form  and/or  terms  of  such  certificates,  documents  or
          conditions;

          of  the  series  to any  Holder  who is  not a  United  States  person
          (including any modification to the definition of such term) in respect
          of any tax,  assessment or governmental charge and, if so, whether the
          Company will have the option to redeem such Securities rather than pay
          such Additional Amounts (and the terms of any such option);

               (22)  the  obligation,  if any,  of the  Company  to  permit  the
          conversion of the Securities of such series into the Company's  Common
          Shares  or  Preferred  Shares,  as the case may be,  and the terms and
          conditions  upon which such conversion  shall be effected  (including,
          without  limitation,   the  initial  conversion  price  or  rate,  the
          conversion period,  any adjustment of the applicable  conversion price
          and any  requirements  relative to the  reservation of such shares for
          purposes of conversion); and

               (23) any other  terms of the  series  (which  terms  shall not be
          inconsistent with the provisions of this Indenture).

     All Securities of any one series and the coupons appertaining to any Bearer
Securities of such series shall be substantially  identical  except, in the case
of  Registered  Securities,  as to  denomination  and except as may otherwise be
provided in or pursuant to such Board  Resolution  (subject to Section  303) and
set forth in such Officers'  Certificate  or in any such indenture  supplemental
hereto.  All  Securities  of any one series  need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

     If any of the terms of the  Securities  of any  series are  established  by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such  action(s)  shall be certified  by the  Secretary or an Assistant
Secretary  of the  Company  and  delivered  to the  Trustee  at or  prior to the
delivery of the Officers'  Certificate setting forth the terms of the Securities
of such series.

               SECTION 302.  Denominations.  The Securities of each series shall
          be  issuable  in  such   denominations   as  shall  be   specified  as
          contemplated  by Section 301. With respect to Securities of any series
          denominated  in Dollars,  in the absence of any such  provisions  with
          respect to the Securities of any series, the Registered  Securities of
          such series,  other than Registered  Securities  issued in global form
          (which may be of any denomination), shall be issuable in denominations
          of $1,000 and any integral  multiple thereof and the Bearer Securities
          of such  series,  other than Bearer  Securities  issued in global form
          (which may be of any denomination), shall be issuable in denominations
          of $5,000, and in any integral multiple thereof.

               SECTION 303. Execution, Authentication,  Delivery and Dating. The
          Securities and any coupons  appertaining  thereto shall be executed on
          behalf of the Company by a Trust Manager and its  Chairman,  its Chief
          Executive  Officer,  its  President,  its Treasurer or one of its Vice
          Presidents  and  attested  by its  Secretary  or one of its  Assistant
          Secretaries.  The  signature  of  any  of  these  individuals  on  the
          Securities  and coupons may be manual or facsimile  signatures  of the
          present or any future such  authorized  officer and trustee and may be
          imprinted or otherwise reproduced on the Securities.

     Securities  or  coupons  bearing  the  manual or  facsimile  signatures  of
individuals  who were at any time the proper  officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Securities or
did not hold such offices at the date of such Securities or coupons.

     At any time and from time to time after the  execution and delivery of this
Indenture,  the Company may deliver Securities of any series,  together with any
coupon  appertaining  thereto,  executed  by  the  Company  to the  Trustee  for
authentication,  together  with a  Company  Order  for  the  authentication  and
delivery  of such  Securities,  and the Trustee in  accordance  with the Company
Order shall authenticate and deliver such Securities;  provided,  however, that,
unless otherwise  specified with respect to any series of Securities pursuant to
Section 301, a Bearer  Security may be delivered in connection with its original
issuance only if the Person  entitled to receive such Bearer Security shall have
furnished a certificate  to Euroclear or CEDEL,  as the case may be, in the form
set forth in Exhibit A-1 to this  Indenture or such other  certificate as may be
specified  with  respect to any series of  Securities  pursuant to Section  301,
dated no  earlier  than 15 days  prior to the  earlier of the date on which such
Bearer Security is delivered and the date on which any temporary  Security first
becomes  exchangeable  for such Bearer  Security in accordance with the terms of
such temporary Security and this Indenture. If any Security shall be represented
by a permanent  global Bearer  Security,  then, for purposes of this Section and
Section 304, the notation of a beneficial owner's interest therein upon original
issuance of such  Security or upon  exchange of a portion of a temporary  global
Security shall be deemed to be delivery in connection with its original issuance
of such beneficial owner's interest in such permanent global Security. Except as
permitted  by Section  306,  the Trustee or the  Authenticating  Agent shall not
authenticate and deliver any Bearer Security unless all appurtenant  coupons for
interest then matured have been detached and cancelled.

     If all of the Securities of any series are not to be issued at one time and
if the Board Resolution or supplemental indenture establishing such series shall
so permit, such Company Order may set forth procedures acceptable to the Trustee
for the issuance of such  Securities  and  determining  the terms of  particular
Securities of such series, such as interest rate or formula, maturity date, date
of issuance and date from which interest shall accrue.  In  authenticating  such
Securities,  and accepting the additional  responsibilities under this Indenture
in relation to such  Securities,  the Trustee shall be entitled to receive,  and
(subject to TIA Sections  315(a)  through  315(d))  shall be fully  protected in
relying upon:

               (1) an Opinion of Counsel stating that:

                    (a) the  form or forms of such  Securities  and any  coupons
               have been  established in conformity  with the provisions of this
               Indenture;

                    (b) the terms of such  Securities  and any coupons have been
               established in conformity  with the provisions of this Indenture;
               and

                    (c) such Securities,  together with any coupons appertaining
               thereto,  when completed by  appropriate  insertions and executed
               and delivered by the Company to the Trustee for authentication in
               accordance  with this Indenture,  authenticated  and delivered by
               the Trustee in accordance  with this  Indenture and issued by the
               Company in the manner and subject to any conditions  specified in
               such Opinion of Counsel, will constitute legal, valid and binding
               obligations of the Company,  enforceable in accordance with their
               terms,    subject   to   applicable    bankruptcy,    insolvency,
               reorganization  and other  similar laws of general  applicability
               relating to or affecting the  enforcement  of  creditors'  rights
               generally and to general equitable principles; and

               (2)  an  Officers'   Certificate   stating  that  all  conditions
          precedent  provided for in this Indenture  relating to the issuance of
          the  Securities  have been  complied with and that, to the best of the
          knowledge of the signers of such certificate, no Event of Default with
          respect  to  any  of  the  Securities   shall  have  occurred  and  be
          continuing.

If such  form or terms  have  been so  established,  the  Trustee  shall  not be
required  to  authenticate  such  Securities  if the  issue  of such  Securities
pursuant  to this  Indenture  will  affect the  Trustee's  own  rights,  duties,
obligations  or immunities  under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

     Notwithstanding  the  provisions  of  Section  301  and  of  the  preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant  to  Section  301 or a Company  Order,  or an  Opinion of Counsel or an
Officers'  Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each  Security of such series,  but such order,  opinion
and certificates, with appropriate modifications to cover such future issuances,
shall be  delivered  at or before the time of issuance of the first  Security of
such series.

     Each Registered  Security shall be dated the date of its authentication and
each Bearer  Security shall be dated as of the date specified as contemplated by
Section 301.

     No Security or coupon shall be entitled to any benefit under this Indenture
or be valid or obligatory  for any purpose unless there appears on such Security
or Security to which such coupon  appertains  a  certificate  of  authentication
substantially  in the form  provided for herein duly  executed by the Trustee by
manual  signature of an  authorized  signatory,  and such  certificate  upon any
Security shall be conclusive evidence, and the only evidence, that such Security
has been duly  authenticated  and  delivered  hereunder  and is  entitled to the
benefits of this Indenture. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the
Company,  and the  Company  shall  deliver  such  Security  to the  Trustee  for
cancellation as provided in Section 309 together with a written statement (which
need not comply with  Section 102 and need not be  accompanied  by an Opinion of
Counsel)  stating  that such  Security  has never  been  issued  and sold by the
Company,  for all purposes of this Indenture such Security shall be deemed never
to have been  authenticated and delivered  hereunder and shall never be entitled
to the benefits of this Indenture.

               SECTION 304. Temporary Securities. (1) Pending the preparation of
          definitive Securities of any series, the Company may execute, and upon
          Company Order the Trustee shall  authenticate  and deliver,  temporary
          Securities which are printed, lithographed,  typewritten, mimeographed
          or otherwise produced, in any authorized  denomination,  substantially
          of the tenor of the  definitive  Securities  in lieu of which they are
          issued, in registered form, or, if authorized, in bearer form with one
          or  more  coupons  or  without  coupons,  and  with  such  appropriate
          insertions,  omissions,  substitutions  and  other  variations  as the
          officers  executing such  Securities may  determine,  as  conclusively
          evidenced  by  their  execution  of such  Securities.  In the  case of
          Securities of any series,  such temporary  Securities may be in global
          form.

     Except in the case of temporary  Securities  in global form (which shall be
exchanged  in  accordance  with Section  304(2) or as  otherwise  provided in or
pursuant  to a Board  Resolution),  if  temporary  Securities  of any series are
issued,  the  Company  will cause  definitive  Securities  of that  series to be
prepared  without  unreasonable  delay.  After  the  preparation  of  definitive
Securities  of such series,  the  temporary  Securities  of such series shall be
exchangeable  for  definitive  Securities  of such series upon  surrender of the
temporary  Securities of such series at the office or agency of the Company in a
Place of Payment for that series,  without charge to the Holder.  Upon surrender
for  cancellation  of any  one  or  more  temporary  Securities  of  any  series
(accompanied by any non-matured coupons appertaining thereto), the Company shall
execute and the Trustee shall  authenticate  and deliver in exchange  therefor a
like principal amount of definitive  Securities of the same series of authorized
denominations;  provided,  however,  that no definitive Bearer Security shall be
delivered in exchange for a temporary Registered Security; and provided further,
that a definitive Bearer Security shall be delivered in exchange for a temporary
Bearer Security only in compliance with the conditions set forth in Section 303.
Until so exchanged, the temporary Securities of any series shall in all respects
be entitled to the same benefits under this  Indenture as definitive  Securities
of such series.

               (2)  Unless  otherwise   provided  in  or  pursuant  to  a  Board
          Resolution, this Section 304(2) shall govern the exchange of temporary
          Securities  issued in global form other than through the facilities of
          The Depository Trust Company ("DTC").  If any such temporary  Security
          is issued in global form,  then such temporary  global Security shall,
          unless otherwise  provided therein,  be delivered to the London office
          of a depositary or common  depositary (the "Common  Depositary"),  for
          the  benefit  of  Euroclear  and CEDEL,  for credit to the  respective
          accounts of the beneficial owners of such Securities (or to such other
          accounts as they may direct).

     Without  unnecessary  delay  but in any  event  not  later  than  the  date
specified in, or determined  pursuant to the terms of, any such temporary global
Security  (the  "Exchange  Date"),  the  Company  shall  deliver to the  Trustee
definitive  Securities,  in aggregate  principal  amount equal to the  principal
amount of such temporary global Security,  executed by the Company.  On or after
the Exchange Date,  such temporary  global  Security shall be surrendered by the
Common Depositary to the Trustee,  or its agent, as the Company's agent for such
purpose,  to be  exchanged,  in  whole  or,  from  time to time,  in  part,  for
definitive  Securities  without charge,  and the Trustee shall  authenticate and
deliver,  in exchange for each portion of such  temporary  global  Security,  an
equal aggregate principal amount of definitive  Securities of the same series of
authorized  denominations  and of like tenor as the  portion  of such  temporary
global  Security to be exchanged.  The definitive  Securities to be delivered in
exchange  for any  such  temporary  global  Security  shall be in  bearer  form,
registered form,  permanent  global bearer form or permanent  global  registered
form, or any combination  thereof,  as specified as contemplated by Section 301,
and, if any combination thereof is so specified,  as requested by the beneficial
owner thereof;  provided,  however,  that,  unless  otherwise  specified in such
temporary global Security, upon such presentation by the Common Depositary, such
temporary  global  Security is accompanied  by a certificate  dated the Exchange
Date or a  subsequent  date and signed by  Euroclear  as to the  portion of such
temporary  global  Security  held for its  account  then to be  exchanged  and a
certificate  dated the Exchange Date or a subsequent date and signed by CEDEL as
to the portion of such temporary global Security held for its account then to be
exchanged,  each in the form set forth in Exhibit  A-2 to this  Indenture  or in
such other form as may be  established  pursuant to Section  301;  and  provided
further, that, definitive Bearer Securities shall be delivered in exchange for a
portion of a temporary  global Security only in compliance with the requirements
of Section 303.

     Unless otherwise specified in such temporary global Security,  the interest
of a beneficial  owner of Securities of a series in a temporary  global Security
shall be  exchanged  for  definitive  Securities  of the same series and of like
tenor following the Exchange Date when the account holder instructs Euroclear or
CEDEL,  as the case may be, to request such  exchange on his behalf and delivers
to Euroclear or CEDEL,  as the case may be, a certificate  in the form set forth
in Exhibit A-1 to this  Indenture  (or in such other form as may be  established
pursuant to Section  301),  dated no earlier  than 15 days prior to the Exchange
Date,  copies  of which  certificate  shall be  available  from the  offices  of
Euroclear and CEDEL, the Trustee,  any  Authenticating  Agent appointed for such
series of Securities and each Paying Agent.  Unless otherwise  specified in such
temporary global Security, any such exchange shall be made free of charge to the
beneficial  owners  of such  temporary  global  Security,  except  that a Person
receiving  definitive  Securities  must  bear  the cost of  insurance,  postage,
transportation and the like unless such Person takes delivery of such definitive
Securities in person at the offices of Euroclear or CEDEL. Definitive Securities
in bearer form to be delivered in exchange for any portion of a temporary global
Security shall be delivered only outside the United States.

     Until exchanged in full as hereinabove  provided,  the temporary Securities
of any series shall in all respects be entitled to the same benefits  under this
Indenture  as  definitive  Securities  of the  same  series  and of  like  tenor
authenticated and delivered  hereunder,  except that, unless otherwise specified
as contemplated by Section 301,  interest payable on a temporary global Security
on an Interest Payment Date for Securities of such series occurring prior to the
applicable  Exchange  Date  shall be  payable  to  Euroclear  and  CEDEL on such
Interest  Payment Date upon  delivery by Euroclear and CEDEL to the Trustee of a
certificate  or  certificates  in the form  set  forth  in  Exhibit  A-2 to this
Indenture  (or in such other  forms as may be  established  pursuant  to Section
301), for credit without further interest on or after such Interest Payment Date
to the  respective  accounts  of Persons who are the  beneficial  owners of such
temporary  global  Security  on such  Interest  Payment  Date and who have  each
delivered  to  Euroclear or CEDEL,  as the case may be, a  certificate  dated no
earlier than 15 days prior to the Interest  Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such
other  forms as may be  established  pursuant to Section  301).  Notwithstanding
anything to the contrary herein contained,  the certifications  made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section  304(2) and of the third  paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners of
the temporary global Security with respect to which such  certification was made
will be exchanged for definitive Securities of the same series and of like tenor
on the Exchange Date or the date of  certification if such date occurs after the
Exchange Date, without further act or deed by such beneficial owners.  Except as
otherwise provided in this paragraph, no payments of principal or interest owing
with respect to a beneficial  interest in a temporary  global  Security  will be
made unless and until such interest in such temporary global Security shall have
been  exchanged  for an  interest  in a  definitive  Security.  Any  interest so
received  by  Euroclear  and  CEDEL  and not paid as  herein  provided  shall be
returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

               SECTION 305. Registration, Registration of Transfer and Exchange.
          The Company  shall cause to be kept at the  Corporate  Trust Office of
          the  Trustee or in any  office or agency of the  Company in a Place of
          Payment a  register  for each  series  of  Securities  (the  registers
          maintained  in such  office  or in any such  office  or  agency of the
          Company in a Place of  Payment  being  herein  sometimes  referred  to
          collectively  as the "Security  Register")  in which,  subject to such
          reasonable regulations as it may prescribe,  the Company shall provide
          for the  registration  of  Registered  Securities  and of transfers of
          Registered Securities.  The Security Register shall be in written form
          or any other form capable of being  converted into written form within
          a reasonable  time.  The Trustee,  at its Corporate  Trust Office,  is
          hereby appointed  "Security  Registrar" for the purpose of registering
          Registered  Securities and transfers of Registered  Securities on such
          Security  Register as herein  provided.  In the event that the Trustee
          shall  cease to be  Security  Registrar,  it shall  have the  right to
          examine the Security Register at all reasonable times.

     Subject  to  the  provisions  of  this  Section  305,  upon  surrender  for
registration of transfer of any Registered  Security of any series at any office
or agency of the  Company in a Place of Payment  for that  series,  the  Company
shall execute,  and the Trustee shall  authenticate and deliver,  in the name of
the designated transferee or transferees,  one or more new Registered Securities
of the same series,  of any  authorized  denominations  and of a like  aggregate
principal  amount,  bearing  a number  not  contemporaneously  outstanding,  and
containing identical terms and provisions.

     Subject to the provisions of this Section 305, at the option of the Holder,
Registered  Securities  of any  series  may be  exchanged  for other  Registered
Securities of the same series,  of any authorized  denomination or denominations
and of a  like  aggregate  principal  amount,  containing  identical  terms  and
provisions,  upon surrender of the Registered  Securities to be exchanged at any
such  office  or  agency.   Whenever  any  such  Registered  Securities  are  so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Registered  Securities which the Holder making the
exchange is entitled to receive.  Unless otherwise specified with respect to any
series of Securities as contemplated  by Section 301, Bearer  Securities may not
be issued in exchange for Registered Securities.

     If (but only if) permitted by the applicable  Board Resolution and (subject
to Section 303) set forth in the  applicable  Officers'  Certificate,  or in any
indenture supplemental hereto,  delivered as contemplated by Section 301, at the
option of the  Holder,  Bearer  Securities  of any series may be  exchanged  for
Registered Securities of the same series of any authorized  denominations and of
a like  aggregate  principal  amount and  tenor,  upon  surrender  of the Bearer
Securities  to be  exchanged  at any such office or agency,  with all  unmatured
coupons and all matured coupons in default thereto  appertaining.  If the Holder
of a Bearer  Security is unable to produce any such unmatured  coupon or coupons
or matured  coupon or coupons in default,  any such  permitted  exchange  may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such  missing  coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may  require,  in their  sole  discretion,  to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to any Paying Agent any such  missing  coupon in respect of which such a payment
shall have been made,  such  Holder  shall be  entitled to receive the amount of
such payment;  provided,  however, that, except as otherwise provided in Section
1002,  interest  represented by coupons shall be payable only upon  presentation
and surrender of those coupons at an office or agency located outside the United
States.  Notwithstanding the foregoing,  in case a Bearer Security of any series
is  surrendered  at any such  office  or agency in a  permitted  exchange  for a
Registered  Security  of the same  series  and like  tenor  after  the  close of
business at such office or agency on (i) any Regular  Record Date and before the
opening of business at such office or agency on the  relevant  Interest  Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer  Security shall be surrendered  without the coupon  relating to such
Interest  Payment  Date or proposed  date for  payment,  as the case may be, and
interest or Defaulted Interest,  as the case may be, will not be payable on such
Interest  Payment  Date or  proposed  date for  payment,  as the case may be, in
respect of the Registered  Security issued in exchange for such Bearer Security,
but will be payable  only to the Holder of such  coupon  when due in  accordance
with  the  provisions  of  this  Indenture.   Whenever  any  Securities  are  so
surrendered  for  exchange,  the Company  shall  execute,  and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

     Notwithstanding   the   foregoing,   except  as   otherwise   specified  as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph.  If the depositary for any permanent  global
Security is DTC, then, unless the terms of such global Security expressly permit
such  global  Security  to be  exchanged  in  whole  or in part  for  definitive
Securities,  a global  Security may be transferred,  in whole,  but not in part,
only to a nominee of DTC, or by a nominee of DTC to DTC,  or to a  successor  to
DTC for such global Security selected or approved by the Company or to a nominee
of such  successor  to DTC. If at any time DTC  notifies  the Company that it is
unwilling or unable to continue as depositary for the applicable global Security
or  Securities or if at any time DTC ceases to be a clearing  agency  registered
under the  Securities  Exchange Act of 1934 if so required by applicable  law or
regulation,  the Company  shall appoint a successor  depositary  with respect to
such global  Security or  Securities.  If (x) a  successor  depositary  for such
global  Security or Securities  is not  appointed by the Company  within 90 days
after the Company  receives such notice or becomes aware of such  unwillingness,
inability  or  ineligibility,  (y) an  Event  of  Default  has  occurred  and is
continuing and the beneficial owners representing a majority in principal amount
of the applicable  series of Securities  represented by such global  Security or
Securities  advise DTC to cease acting as depositary for such global Security or
Securities or (z) the Company,  in its sole  discretion,  determines at any time
that all Outstanding  Securities (but not less than all) of any series issued or
issuable  in the  form of one or more  global  Securities  shall  no  longer  be
represented  by such global  Security  or  Securities,  then the  Company  shall
execute, and the Trustee shall authenticate and deliver definitive Securities of
like series,  rank, tenor and terms in definitive form in an aggregate principal
amount equal to the principal  amount of such global Security or Securities.  If
any beneficial  owner of an interest in a permanent global Security is otherwise
entitled to exchange  such  interest for  Securities  of such series and of like
tenor and  principal  amount of another  authorized  form and  denomination,  as
specified as contemplated by Section 301 and provided that any applicable notice
provided in the permanent  global  Security shall have been given,  then without
unnecessary  delay but in any event not later  than the  earliest  date on which
such interest may be so exchanged,  the Company shall  execute,  and the Trustee
shall  authenticate  and deliver  definitive  Securities in aggregate  principal
amount equal to the principal amount of such beneficial owner's interest in such
permanent global Security. On or after the earliest date on which such interests
may be so exchanged,  such permanent  global  Security shall be surrendered  for
exchange by DTC or such other  depositary  as shall be  specified in the Company
Order with  respect  thereto to the  Trustee,  as the  Company's  agent for such
purpose;  provided,  however,  that no such  exchanges may occur during a period
beginning at the opening of business 15 days before any  selection of Securities
to be redeemed and ending on the relevant  Redemption  Date, if the Security for
which  exchange is requested may be among those  selected for  redemption.  If a
Registered  Security is issued in exchange for any portion of a permanent global
Security after the close of business at the office or agency where such exchange
occurs on (i) any Regular Record Date and before the opening of business at such
office or agency on the  relevant  Interest  Payment  Date,  or (ii) any Special
Record  Date and the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, Interest or Defaulted Interest,
as the case  may be,  will  not be  payable  on such  Interest  Payment  Date or
proposed  date for  payment,  as the case may be, in respect of such  Registered
Security, but will be payable on such Interest Payment Date or proposed date for
payment,  as the case may be, only to the Person to whom  interest in respect of
such portion of such permanent global Security is payable in accordance with the
provisions of this Indenture.

     All  Securities  issued  upon any  registration  of transfer or exchange of
Securities  shall be the valid  obligations of the Company,  evidencing the same
debt, and entitled to the same benefits under this Indenture,  as the Securities
surrendered upon such registration of transfer or exchange.

     Every  Registered  Security  presented or surrendered  for  registration of
transfer or for exchange or  redemption  shall (if so required by the Company or
the  Security  Registrar)  be duly  endorsed,  or be  accompanied  by a  written
instrument  of transfer  in form  satisfactory  to the Company and the  Security
Registrar,  duly executed by the Holder thereof or his attorney duly  authorized
in writing.

     No  service  charge  shall  be made for any  registration  of  transfer  or
exchange of Securities,  but the Company may require payment of a sum sufficient
to cover any tax or other governmental  charge that may be imposed in connection
with any  registration  of  transfer  or  exchange  of  Securities,  other  than
exchanges  pursuant  to  Sections  304,  906,  1107 or 1305  not  involving  any
transfer.

     The Company or the  Trustee,  as  applicable,  shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may be
among those selected for redemption  during a period beginning at the opening of
business 15 days before selection of the Securities to be redeemed under Section
1103 and ending at the close of business on (A) if such  Securities are issuable
only as Registered Securities,  the day of the mailing of the relevant notice of
redemption and (B) if such Securities are issuable as Bearer Securities, the day
of the  first  publication  of the  relevant  notice of  redemption  or, if such
Securities  are  also  issuable  as  Registered   Securities  and  there  is  no
publication,  the  mailing  of the  relevant  notice of  redemption,  or (ii) to
register  the transfer of or exchange  any  Registered  Security so selected for
redemption in whole or in part,  except, in the case of any Registered  Security
to be redeemed  in part,  the portion  thereof not to be  redeemed,  or (iii) to
exchange  any Bearer  Security so  selected  for  redemption  except that such a
Bearer  Security may be exchanged  for a Registered  Security of that series and
like tenor,  provided  that such  Registered  Security  shall be  simultaneously
surrendered  for  redemption,  or (iv) to issue,  register  the  transfer  of or
exchange any Security which has been  surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

               SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities. If
          any  mutilated   Security  or  a  Security  with  a  mutilated  coupon
          appertaining  to it is  surrendered  to the  Trustee  or the  Company,
          together  with, in proper cases,  such security or indemnity as may be
          required  by the  Company  or the  Trustee to save each of them or any
          agent of either of them  harmless,  the Company  shall execute and the
          Trustee  shall  authenticate  and deliver in  exchange  therefor a new
          Security of the same series and principal amount, containing identical
          terms  and  provisions  and  bearing  a number  not  contemporaneously
          outstanding,  with  coupons  corresponding  to the  coupons,  if  any,
          appertaining to the surrendered Security.

     If there shall be  delivered to the Company and to the Trustee (i) evidence
to their  satisfaction  of the  destruction,  loss or theft of any  Security  or
coupon,  and (ii) such  security or indemnity as may be required by them to save
each of them and any agent of either of them  harmless,  then, in the absence of
notice to the  Company  or the  Trustee  that such  Security  or coupon has been
acquired  by a bona fide  purchaser,  the  Company  shall  execute  and upon its
request  the  Trustee  shall  authenticate  and  deliver,  in lieu  of any  such
destroyed,  lost or stolen  Security or in exchange  for the Security to which a
destroyed,  lost or stolen coupon  appertains (with all appurtenant  coupons not
destroyed,  lost or stolen),  a new  Security  of the same series and  principal
amount,  containing  identical  terms and  provisions  and  bearing a number not
contemporaneously  outstanding,  with coupons  corresponding to the coupons,  if
any, appertaining to such destroyed,  lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

     Notwithstanding the provisions of the previous two paragraphs,  in case any
such  mutilated,  destroyed,  lost or stolen Security or coupon has become or is
about to become due and payable,  the Company in its discretion may,  instead of
issuing a new  Security,  with coupons  corresponding  to the  coupons,  if any,
appertaining  to such  destroyed,  lost or stolen Security or to the Security to
which such  destroyed,  lost or stolen coupon  appertains,  pay such Security or
coupon;  provided,  however, that payment of principal of (and premium, if any),
any interest on and any  Additional  Amounts with respect to, Bearer  Securities
shall,  except as  otherwise  provided in Section  1002,  be payable  only at an
office or agency  located  outside  the  United  States  and,  unless  otherwise
specified as  contemplated  by Section  301,  any interest on Bearer  Securities
shall  be  payable  only  upon   presentation   and  surrender  of  the  coupons
appertaining  thereto. Upon the issuance of any new Security under this Section,
the Company may  require  the  payment of a sum  sufficient  to cover any tax or
other governmental  charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

     Every new Security of any series with its coupons,  if any, issued pursuant
to this  Section  in lieu of any  destroyed,  lost  or  stolen  Security,  or in
exchange for a Security to which a destroyed,  lost or stolen coupon appertains,
shall constitute an original additional  contractual  obligation of the Company,
whether or not the destroyed,  lost or stolen Security and its coupons,  if any,
or the  destroyed,  lost or stolen  coupon shall be at any time  enforceable  by
anyone,  and shall be entitled to all the benefits of this Indenture equally and
proportionately  with any and all  other  Securities  of that  series  and their
coupons, if any, duly issued hereunder.

     The  provisions of this Section are  exclusive  and shall  preclude (to the
extent lawful) all other rights and remedies with respect to the  replacement or
payment of mutilated, destroyed, lost or stolen Securities or coupons.

               SECTION 307.  Payment of  Interest;  Interest  Rights  Preserved.
          Except as otherwise  specified  with respect to a series of Securities
          in  accordance  with the  provisions  of Section 301,  interest on any
          Registered  Security that is payable,  and is punctually  paid or duly
          provided for, on any Interest Payment Date shall be paid to the Person
          in whose name that Security (or one or more Predecessor Securities) is
          registered  at the close of business  on the  Regular  Record Date for
          such  interest at the office or agency of the Company  maintained  for
          such purpose pursuant to Section 1002;  provided,  however,  that each
          installment  of  interest  on  any  Registered  Security  may  at  the
          Company's  option be paid by (i)  mailing  a check for such  interest,
          payable to or upon the written  order of the Person  entitled  thereto
          pursuant  to Section  308, to the address of such Person as it appears
          on the Security Register or (ii) transfer to an account  maintained by
          the payee located inside the United States.

     Unless  otherwise  provided as  contemplated by Section 301 with respect to
the Securities of any series,  payment of interest may be made, in the case of a
Bearer Security,  by transfer to an account  maintained by the payee with a bank
located outside the United States.

     Unless  otherwise  provided as contemplated by Section 301, every permanent
global  Security  will provide that  interest,  if any,  payable on any Interest
Payment Date will be paid to DTC,  Euroclear  and/or CEDEL,  as the case may be,
with  respect to that portion of such  permanent  global  Security  held for its
account  by Cede & Co. or the  Common  Depositary,  as the case may be,  for the
purpose  of  permitting  such  party to credit the  interest  received  by it in
respect of such  permanent  global  Security to the  accounts of the  beneficial
owners thereof.

     In case a Bearer  Security of any series is  surrendered  in exchange for a
Registered  Security of such series after the close of business (at an office or
agency in a Place of Payment  for such  series) on any  Regular  Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest  Payment Date,  such Bearer  Security shall be surrendered  without the
coupon  relating to such Interest  Payment Date and interest will not be payable
on such Interest  Payment Date in respect of the Registered  Security  issued in
exchange  for such Bearer  Security,  but will be payable  only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

     Except as otherwise  specified  with respect to a series of  Securities  in
accordance  with the  provisions of Section 301, any interest on any  Registered
Security  of any series  that is  payable,  but is not  punctually  paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted  Interest")
shall  forthwith  cease to be payable to the  registered  Holder  thereof on the
relevant  Regular  Record  Date by virtue of having been such  Holder,  and such
Defaulted Interest may be paid by the Company,  at its election in each case, as
provided in clause (1) or (2) below:

                    (1) The Company may elect to make  payment of any  Defaulted
               Interest to the Persons in whose names the Registered  Securities
               of such series (or their respective  Predecessor  Securities) are
               registered at the close of business on a Special  Record Date for
               the payment of such Defaulted  Interest,  which shall be fixed in
               the  following  manner.  The Company  shall notify the Trustee in
               writing of the amount of Defaulted  Interest  proposed to be paid
               on each  Registered  Security  of such series and the date of the
               proposed payment (which shall not be less than 30 days after such
               notice  is  received  by the  Trustee),  and at the same time the
               Company  shall deposit with the Trustee an amount of money in the
               currency  or  currencies,  currency  unit or units  or  composite
               currency or currencies in which the Securities of such series are
               payable  (except as otherwise  specified  pursuant to Section 301
               for the Securities of such series) equal to the aggregate  amount
               proposed  to be paid in respect  of such  Defaulted  Interest  or
               shall make  arrangements  satisfactory  to the  Trustee  for such
               deposit  on or prior to the date of the  proposed  payment,  such
               money when  deposited  to be held in trust for the benefit of the
               Persons  entitled  to such  Defaulted  Interest as in this clause
               provided.  Thereupon the Trustee shall fix a Special  Record Date
               for the  payment of such  Defaulted  Interest  which shall be not
               more than 15 days and not less then 10 days  prior to the date of
               the proposed  payment and not less than 15 days after the receipt
               by the Trustee of the notice of the proposed payment. The Trustee
               shall  promptly  notify the Company of such  Special  Record Date
               and, in the name and at the expense of the  Company,  shall cause
               notice of the proposed payment of such Defaulted Interest and the
               Special  Record Date  therefor to be mailed,  first class postage
               prepaid,  to each Holder of Registered  Securities of such series
               at his address as it appears in the  Security  Register  not less
               than 10 days prior to such Special  Record Date. The Company may,
               in its discretion,  direct the Trustee to publish in the name and
               at the  expense  of the  Company,  cause a  similar  notice to be
               published at least once in an Authorized  Newspaper in each Place
               of  Payment,  but  such  publications  shall  not be a  condition
               precedent  to the  establishment  of such  Special  Record  Date.
               Notice of the proposed payment of such Defaulted Interest and the
               Special  Record Date  therefor  having been mailed as  aforesaid,
               such  Defaulted  Interest  shall be paid to the  Persons in whose
               names  the  Registered   Securities  of  such  series  (or  their
               respective Predecessor Securities) are registered at the close of
               business  on such  Special  Record  Date and  shall no  longer be
               payable  pursuant to the  following  clause (2). In case a Bearer
               Security of any series is  surrendered at the office or agency in
               a Place of Payment for such series in exchange  for a  Registered
               Security  of such  series  after  the close of  business  at such
               office  or agency  on any  Special  Record  Date and  before  the
               opening  of  business  at such  office or  agency on the  related
               proposed  date for  payment of  Defaulted  Interest,  such Bearer
               Security shall be surrendered without the coupon relating to such
               proposed  date of  payment  and  Defaulted  Interest  will not be
               payable  on such  proposed  date of  payment  in  respect  of the
               Registered  Security issued in exchange for such Bearer Security,
               but will be payable only to the Holder of such coupon when due in
               accordance with the provisions of this Indenture; or

                    (2) The Company may make payment of any  Defaulted  Interest
               on the  Registered  Securities  of any series in any other lawful
               manner not  inconsistent  with the requirements of any securities
               exchange on which such  Securities  may be listed,  and upon such
               notice as may be  required by such  exchange,  if,  after  notice
               given by the  Company  to the  Trustee  of the  proposed  payment
               pursuant to this clause,  such manner of payment  shall be deemed
               practicable by the Trustee.

     Subject to the  foregoing  provisions of this Section and Section 305, each
Security  delivered under this Indenture upon  registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

               SECTION 308. Persons Deemed Owners. Prior to due presentment of a
          Registered  Security for  registration of transfer,  the Company,  the
          Trustee  and any agent of the  Company  or the  Trustee  may treat the
          Person in whose name such  Registered  Security is  registered  as the
          owner  of such  Security  for the  purpose  of  receiving  payment  of
          principal of (and premium,  if any),  and (subject to Sections 305 and
          307) interest on, such Registered  Security and for all other purposes
          whatsoever,  whether or not such Registered  Security be overdue,  and
          neither the  Company,  the Trustee nor any agent of the Company or the
          Trustee shall be affected by notice to the contrary.

     Title to any Bearer  Security and any coupons  appertaining  thereto  shall
pass by delivery.  The Company,  the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the  absolute  owner of such  Security or coupon for the purpose of receiving
payment  thereof or on account  thereof and for all other  purposes  whatsoever,
whether or not such Security or coupon be overdue,  and neither the Company, the
Trustee nor any agent of the Company or the Trustee  shall be affected by notice
to the contrary.

     None  of the  Company,  the  Trustee,  any  Paying  Agent  or the  Security
Registrar  will  have any  responsibility  or  liability  for any  aspect of the
records  relating  to or  payments  made  on  account  of  beneficial  ownership
interests  of a  Security  in global  form or for  maintaining,  supervising  or
reviewing any records relating to such beneficial ownership interests.

     Notwithstanding the foregoing, with respect to any global Security, nothing
herein shall  prevent the Company,  the Trustee,  or any agent of the Company or
the Trustee,  from giving  effect to any written  certification,  proxy or other
authorization  furnished by any  depositary,  as a Holder,  with respect to such
global  Security or impair,  as between such depositary and owners of beneficial
interests  in  such  global  Security,  the  operation  of  customary  practices
governing  the  exercise of the rights of such  depositary  (or its  nominee) as
Holder of such global Security.

               SECTION 309. Cancellation. All Securities and coupons surrendered
          for  payment,  redemption,  repayment  at the  option  of the  Holder,
          registration of transfer or exchange or for credit against any sinking
          fund  payment  shall,  if  surrendered  to any  Person  other than the
          Trustee,  be  delivered to the Trustee,  and any such  Securities  and
          coupons and Securities and coupons surrendered directly to the Trustee
          for any such  Purpose  shall be promptly  cancelled  by it;  provided,
          however,  where the Place of Payment is located  outside of the United
          States,  the  Paying  Agent at such  Place of  Payment  may cancel the
          Securities surrendered to it for such purposes prior to delivering the
          Securities to the Trustee.  The Company may at any time deliver to the
          Trustee for cancellation any Securities  previously  authenticated and
          delivered  hereunder which the Company may have acquired in any manner
          whatsoever, and may deliver to the Trustee (or to any other Person for
          delivery to the Trustee) for  cancellation  any Securities  previously
          unauthenticated  hereunder  which the Company has not issued and sold,
          and all  Securities  so delivered  shall be promptly  cancelled by the
          Trustee.  If the  Company  shall  so  acquire  any of the  Securities,
          however,  such  acquisition  shall  not  operate  as a  redemption  or
          satisfaction of the indebtedness represented by such Securities unless
          and until the same are surrendered to the Trustee for cancellation. No
          Securities  shall be  authenticated  in lieu of or in exchange for any
          Securities cancelled as provided in this Section,  except as expressly
          permitted by this Indenture.  Cancelled Securities and coupons held by
          the Trustee  shall be destroyed  by the Trustee and the Trustee  shall
          deliver a certificate of such destruction to the Company,  unless by a
          Company Order the Company directs their return to it.

               SECTION  310.  Computation  of  Interest.   Except  as  otherwise
          specified as contemplated by Section 301 with respect to Securities of
          any  series,  interest  on the  Securities  of each  series  shall  be
          computed on the basis of a 360-day year  consisting  of twelve  30-day
          months.

          1011),  and the Trustee,  upon receipt of a Company Order,  and at the
          expense of the Company, shall execute proper instruments acknowledging
          satisfaction and discharge of this Indenture as to such series when

                    arrangements  satisfactory  to the Trustee for the giving of
                    notice of redemption by the Trustee in the name,  and at the
                    expense, of the Company,

                  and the Company,  in the case of (i), (ii) or (iii) above, has
                  irrevocably  deposited  or  caused  to be  deposited  with the
                  Trustee as trust  funds in trust for the  purpose an amount in

                  entire  indebtedness  on such  Securities and such coupons not
                  theretofore  delivered  to the Trustee for  cancellation,  for
                  principal  (and  premium,  if  any)  and  interest,   and  any
                  Additional  Amounts with respect thereto,  to the date of such
                  deposit (in the case of  Securities  which have become due and
                  payable) or to the Stated Maturity or Redemption  Date, as the
                  case may be;

               (2) the  Company  has paid or caused  to be paid all  other  sums
          payable hereunder by the Company; and

               (3)  the  Company  has  delivered  to  the  Trustee  an  Officers
          Certificate  and  an  Opinion  of  Counsel,   each  stating  that  all
          conditions  precedent herein provided for relating to the satisfaction
          and  discharge of this  Indenture as to such series have been complied
          with.

               60 days;  or any  warrant of  attachment  is issued  against  any
               portion  of the  property  of  the  Company  or  any  Significant
               Subsidiary which is not released within 60 days of service; or

                    (8) any other  Event of  Default  provided  with  respect to
               Securities of that series.

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any  similar  Federal  or State law for the  relief of  debtors  and the term
"Custodian" means any receiver,  trustee, assignee,  liquidator or other similar
official under any Bankruptcy Law.

               SECTION 502. Acceleration of Maturity;  Rescission and Annulment.
          If an Event of Default  (other than an Event of Default  specified  in
          Section 501(6) or (7)) with respect to Securities of any series at the
          time Outstanding occurs and is continuing, then and in every such case
          the Trustee or the Holders of not less than 25% in principal amount of
          the  Outstanding  Securities  of that series may declare the principal
          (or, if any  Securities  are Original  Issue  Discount  Securities  or
          Indexed Securities,  such portion of the principal as may be specified
          in the terms  thereof) of all the  Securities of that series to be due
          and payable immediately, by a notice in writing to the Company (and to
          the Trustee it given by the  Holders),  and upon any such  declaration
          such principal or specified  portion thereof shall become  immediately
          due and  payable;  provided,  however,  that if such  Event of Default
          shall occur pursuant to Section 501(6) or Section 501(7) hereof,  such
          acceleration shall be automatic and shall occur without notice.

     At any time  after  such a  declaration  of  acceleration  with  respect to
Securities  of any  series  has been made and  before a  judgment  or decree for
payment of the money due has been obtained by the Trustee as hereinafter in this
Article  provided,  the  Holders  of a  majority  in  principal  amount  of  the
Outstanding  Securities of that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

                    (1) the Company has paid or deposited with the Trustee a sum
               sufficient  to pay in the currency or currency  unit or composite
               currency  in which the  Securities  of such  series  are  payable
               (except as  otherwise  specified  Pursuant to Section 301 for the
               Securities of such series):

                           (A) all overdue  installments  of interest on and any
                  Additional  Amounts  payable  in  respect  of all  Outstanding
                  Securities of that series and any related coupons;

                           (B) the  principal of (and  premium,  if any, on) any
                  Outstanding  Securities  of that series  which have become due
                  otherwise  than  by  such   declaration  of  acceleration  and
                  interest thereon at the rate or rates borne by or provided for
                  in such Securities;

                           (C) to the extent  that  payment of such  interest is
                  lawful, interest upon overdue installments of interest and any
                  Additional  Amounts at the rate or rates  borne by or provided
                  for in such Securities; and

                           (D)  all  sums  paid  or   advanced  by  the  Trustee
                  hereunder   and   the   reasonable   compensation,   expenses,
                  disbursements  and  advances  of the  Trustee,  its agents and
                  counsel; and

                    (2) all Events of Default with respect to Securities of that
               series,  other  than  the  nonpayment  of  the  principal  of (or
               premium,  if any) or interest on  Securities of that series which
               have become due solely by such declaration of acceleration,  have
               been cured or waived as provided in Section 513.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent thereon.

               SECTION 503. Collection of Indebtedness and Suits for Enforcement
          by Trustee. The Company covenants that if:

                    (1)  default is made in the  payment of any  installment  of
               interest or  Additional  Amounts,  if any, on any Security of any
               series and any related  coupon when such  interest or  Additional
               Amount  becomes due and payable and such default  continues for a
               period of 30 days; or

                    (2) default is made in the payment of the  principal  of (or
               premium, if any, on) any Security of any series at its Maturity,

then the Company will, upon demand of the Trustee,  pay to the Trustee,  for the
benefit of the Holders of such Securities of such series and coupons,  the whole
amount then due and payable on such  Securities  and coupons for principal  (and
premium,  if any) and interest and  Additional  Amounts,  with interest upon any
overdue principal (and premium,  if any) and, to the extent that payment of such
interest shall be legally enforceable, upon any overdue installments of interest
or Additional  Amounts, if any, at the rate or rates borne by or provided for in
such  Securities,  and, in addition  thereto,  such  further  amount as shall be
sufficient  to cover  the  costs  and  expenses  of  collection,  including  the
reasonable  compensation,  expenses,  disbursements and advances of the Trustee,
its agents and counsel.

     If the Company fails to pay such amounts  forthwith  upon such demand,  the
Trustee,  in its own name and as trustee of an express  trust,  may  institute a
judicial  proceeding for the  collection of the sums so due and unpaid,  and may
prosecute such proceeding to judgment or final decree,  and may enforce the same
against the Company or any other obligor upon such Securities of such series and
collect the monies  adjudged or decreed to be payable in the manner  provided by
law out of the property of the Company or any other obligor upon such Securities
of such series, wherever situated.

     If an Event of Default with respect to  Securities of any series occurs and
is continuing,  the Trustee may in its discretion proceed to protect and enforce
its rights and the rights of the  Holders of  Securities  of such series and any
related coupons by such  appropriate  judicial  proceedings as the Trustee shall
deem most  effectual  to protect and enforce  any such  rights,  whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

               SECTION  504.  Trustee May File  Proofs of Claim.  In case of the
          pendency of any  receivership,  insolvency,  liquidation,  bankruptcy,
          reorganization, arrangement, adjustment, composition or other judicial
          proceeding  relative  to the  Company  or any other  obligor  upon the
          Securities  or the property of the Company or of such other obligor or
          their creditors, the Trustee (irrespective of whether the principal of
          the  Securities of any series shall then be due and payable as therein
          expressed or by declaration or otherwise and  irrespective  of whether
          the Trustee  shall have made any demand on the Company for the payment
          of overdue principal,  premium, if any, or interest) shall be entitled
          and empowered, by intervention in such proceeding or otherwise:

                    (i) to file and prove a claim for the whole amount,  or such
               lesser  amount as may be provided for in the  Securities  of such
               series,  of  principal  (and  premium,  if any) and  interest and
               Additional  Amounts,  if any,  owing and unpaid in respect of the
               Securities  and to file such other  papers or documents as may be
               necessary or advisable in order to have the claims of the Trustee
               (including any claim for the reasonable  compensation,  expenses,
               disbursements  and  advances  of  the  Trustee,  its  agents  and
               counsel) and of the Holders allowed in such judicial  proceeding;
               and

                    (ii) to collect  and  receive  any monies or other  property
               payable or  deliverable  on any such claims and to distribute the
               same,

and any custodian,  receiver,  assignee, trustee,  liquidator,  sequestrator (or
other similar official) in any such judicial  proceeding is hereby authorized by
each Holder of  Securities  of such series and coupons to make such  payments to
the Trustee,  and in the event that the Trustee  shall  consent to the making of
such payments  directly to the Holders,  to pay to the Trustee any amount due to
it for the reasonable compensation,  expenses, disbursements and advances of the
Trustee and any  predecessor  Trustee,  their agents and counsel,  and any other
amounts due the Trustee or any predecessor Trustee under Section 606.

     Nothing  herein  contained  shall be deemed to  authorize  the  Trustee  to
authorize or consent to or accept or adopt on behalf of any Holder of a Security
or coupon any plan of  reorganization,  arrangement,  adjustment or  composition
affecting the Securities or coupons or the rights of any Holder  thereof,  or to
authorize  the  Trustee  to vote in  respect  of the  claim of any  Holder  of a
Security or coupon in any such proceeding.

               SECTION 505.  Trustee May Enforce  Claims  Without  Possession of
          Securities  or  Coupons.  All rights of action  and claims  under this
          Indenture or any of the  Securities or coupons may be  prosecuted  and
          enforced  by  the  Trustee  without  the  possession  of  any  of  the
          Securities  or coupons  or the  production  thereof in any  proceeding
          relating  thereto,  and any such proceeding  instituted by the Trustee
          shall be brought in its own name as trustee of an express  trust,  and
          any recovery of judgment shall, after provision for the payment of the
          reasonable compensation,  expenses,  disbursements and advances of the
          Trustee,  its agents and  counsel,  be for the ratable  benefit of the
          Holders  of the  Securities  and  coupons  in  respect  of which  such
          judgment has been recovered.

               SECTION 506. Application of Money Collected.  Any money collected
          by the  Trustee  pursuant  to this  Article  shall be  applied  in the
          following  order,  at the date or dates fixed by the  Trustee  and, in
          case of the  distribution  of such money on account of  principal  (or
          premium,  if  any)  or  interest  and  any  Additional  Amounts,  upon
          presentation  of the  Securities or coupons,  or both, as the case may
          be, and the notation thereon of the payment if only partially paid and
          upon surrender thereof if fully paid:

                    FIRST: To the payment of all amounts due the Trustee and any
               predecessor Trustee under Section 606;

                    SECOND:  To the payment of the  amounts  then due and unpaid
               upon the Securities  and coupons for principal  (and premium,  if
               any) and interest and any Additional Amounts payable, in respect,
               of  which  or for the  benefit  of  which  such  money  has  been
               collected,  ratably,  without preference or priority of any kind,
               according  to the  aggregate  amounts  due  and  payable  on such
               Securities  and  coupons for  principal  (and  premium,  if any),
               interest and Additional Amounts, respectively; and

                    THIRD:  To the  payment  of the  remainder,  if any,  to the
               Company.

               SECTION 507.  Limitation  on Suits.  No Holder of any Security of
          any series or any related coupon shall have any right to institute any
          proceeding,  judicial or otherwise, with respect to this Indenture, or
          for the appointment of a receiver or trustee,  or for any other remedy
          hereunder, unless:

                    (1) such Holder has  previously  given written notice to the
               Trustee  of a  continuing  Event of Default  with  respect to the
               Securities of that series;

                    (2) the Holders of not less than 25% in principal  amount of
               the Outstanding Securities of that series shall have made written
               request to the  Trustee to  institute  proceedings  in respect of
               such Event of Default in its own name as Trustee hereunder;

                    (3) such  Holder or  Holders  have  offered  to the  Trustee
               indemnity  reasonably  satisfactory  to the Trustee,  in its sole
               discretion,  against the costs,  expenses and  liabilities  to be
               incurred in compliance with such request;

                    (4)  the  Trustee  for 60 days  after  its  receipt  of such
               notice,  request and offer of  indemnity  has failed to institute
               any such proceeding; and

                    (5) no direction  inconsistent with such written request has
               been  given to the  Trustee  during  such  60-day  period  by the
               Holders  of a majority  in  principal  amount of the  Outstanding
               Securities of that series;

it being  understood and intended that no one or more of such Holders shall have
any right in any manner  whatever by virtue of, or by availing of, any provision
of this  Indenture to affect,  disturb or  prejudice  the rights of any other of
such Holders,  or to obtain or to seek to obtain priority or preference over any
other of such  Holders or to enforce any right under this  Indenture,  except in
the manner  herein  provided  and for the equal and ratable  benefit of all such
Holders.

               SECTION 508. Unconditional Right of Holders to Receive Principal,
          Premium, if any, Interest and Additional Amounts.  Notwithstanding any
          other  provision  in this  Indenture,  the Holder of any  Security  or
          coupon  shall have the right which is absolute  and  unconditional  to
          receive payment of the principal of (and premium, if any) and (subject
          to Sections 305 and 307)  interest on, and any  Additional  Amounts in
          respect of, such Security or payment of such coupon on the  respective
          due dates  expressed  in such  Security  or coupon (or, in the case of
          redemption,  on the  Redemption  Date) and to  institute  suit for the
          enforcement of any such payment, and such rights shall not be impaired
          without the consent of such Holder.

               SECTION 509.  Restoration of Rights and Remedies.  If the Trustee
          or any Holder of a Security or coupon has instituted any proceeding to
          enforce any right or remedy under this  Indenture and such  proceeding
          has  been  discontinued  or  abandoned  for any  reason,  or has  been
          determined  adversely  to the Trustee or to such  Holder,  then and in
          every  such  case,  the  Company,  the  Trustee  and  the  Holders  of
          Securities and coupons  shall,  subject to any  determination  in such
          proceeding,  be restored  severally and  respectively  to their former
          positions  hereunder  and  thereafter  all rights and  remedies of the
          Trustee and the Holders  shall  continue as though no such  proceeding
          had been instituted.

               SECTION 510. Rights and Remedies Cumulative.  Except as otherwise
          provided  with  respect to the  replacement  or payment of  mutilated,
          destroyed,  lost or stolen Securities or coupons in the last paragraph
          of Section 306, no right or remedy herein  conferred  upon or reserved
          to the Trustee or to the Holders of  Securities or coupons is intended
          to be  exclusive  of any other  right or remedy,  and every  right and
          remedy shall,  to the extent  permitted by law, be  cumulative  and in
          addition  to every other right and remedy  given  hereunder  or now or
          hereafter existing at law or in equity or otherwise.  The assertion or
          employment of any right or remedy hereunder,  or otherwise,  shall not
          prevent  the   concurrent   assertion  or   employment  of  any  other
          appropriate right or remedy.

               SECTION 511.  Delay or Omission Not Waiver.  No delay or omission
          of the Trustee or of any Holder of any  Security or coupon to exercise
          any right or remedy  accruing  upon any Event of Default  shall impair
          any such right or remedy or  constitute  a waiver of any such Event of
          Default or an  acquiescence  therein.  Every right and remedy given by
          this  Article  or by law  to the  Trustee  or to  the  Holders  may be
          exercised from time to time, and as often as may be deemed  expedient,
          by the Trustee or by the Holders of Securities or coupons, as the case
          may be.

               SECTION 512. Control by Holders of Securities. The Holders of not
          less than a majority in principal amount of the Outstanding Securities
          of any  series  shall  have the right to direct  the time,  method and
          place of conducting  any  proceeding  for any remedy  available to the
          Trustee or exercising any trust or power conferred on the Trustee with
          respect to the Securities of such series, provided that:

                    (1) such direction shall not be in conflict with any rule of
               law or with this Indenture;

                    (2) the Trustee may take any other action  deemed  proper by
               the Trustee which is not inconsistent with such direction; and

                    (3) the Trustee need not take any action which might involve
               it in personal  liability or be unduly prejudicial to the Holders
               of Securities of such series not joining therein.

               SECTION  513.  Waiver of Past  Defaults.  The Holders of not less
          than a majority in principal  amount of the Outstanding  Securities of
          any series may on behalf of the Holders of all the  Securities of such
          series and any related  coupons waive any past default  hereunder with
          respect to such series and its consequences, except a default

                    (1) in the payment of the principal of (or premium,  if any)
               or interest on or  Additional  Amounts  payable in respect of any
               Security of such series or any related coupons; or

                    (2) in respect of a covenant or provision hereof which under
               Article Nine cannot be modified or amended without the consent of
               the Holder of each Outstanding Security of such series affected.

     Upon any such waiver,  such default shall cease to exist,  and any Event of
Default arising  therefrom shall be deemed to have been cured, for every purpose
of this  Indenture;  but no such waiver shall extend to any  subsequent or other
default or Event of Default or impair any right consequent thereon.

               SECTION 514. Waiver of Usury, Stay or Extension Laws. The Company
          covenants  (to the extent that it may lawfully do so) that it will not
          at any time insist upon, or plead, or in any manner  whatsoever  claim
          or take the benefit or advantage of, any usury,  stay or extension law
          wherever  enacted,  now or at any time  hereafter in force,  which may
          affect the covenants or the  performance  of this  Indenture;  and the
          Company  (to the extent that it may  lawfully do so) hereby  expressly
          waives all benefit or advantage of any such law, and covenants that it
          will not hinder,  delay or impede the  execution  of any power  herein
          granted to the  Trustee,  but will suffer and permit the  execution of
          every such power as though no such law had been enacted.

               SECTION 515. Undertaking for Costs. All parties to this Indenture
          agree, and each Holder of any Security by his acceptance thereof shall
          be  deemed  to have  agreed,  that  any  court  may in its  discretion
          require,  in any suit for the enforcement of any right or remedy under
          this  Indenture,  or in any suit  against  the  Trustee for any action
          taken or omitted by it as Trustee, the filing by any party litigant in
          such suit of any  undertaking  to pay the costs of such suit, and that
          such court may in its discretion assess  reasonable  costs,  including
          reasonable  attorneys'  fees,  against any party litigant in such suit
          having  due  regard  to the  merits  and good  faith of the  claims or
          defenses  made by such  party  litigant;  but the  provisions  of this
          Section shall not apply to any suit instituted by the Trustee,  to any
          suit  instituted  by any Holder,  or group of Holders,  holding in the
          aggregate  more  than  10% in  principal  amount  of  the  Outstanding
          Securities,   or  to  any  suit  instituted  by  any  Holder  for  the
          enforcement of the payment of the principal of (or premium, if any) or
          interest on any Security on or after the respective  Stated Maturities
          expressed in such Security (or, in the case of redemption, on or after
          the Redemption Date).

                                   ARTICLE SIX

                                   THE TRUSTEE

               SECTION  601.  Notice  of  Defaults.  Within  90 days  after  the
          occurrence of any default  hereunder with respect to the Securities of
          any series, the Trustee shall transmit in the manner and to the extent
          provided in TIA Section 313(c), notice of such default hereunder known
          to the Trustee,  unless such default  shall have been cured or waived;
          provided,  however,  that,  except  in the  case of a  default  in the
          payment of the principal of (or premium, if any) or interest on or any
          Additional  Amounts with respect to any Security of such series, or in
          the  payment  of any  sinking  fund  installment  with  respect to the
          Securities  of  such  series,   the  Trustee  shall  be  protected  in
          withholding such notice if and so long as Responsible  Officers of the
          Trustee in good faith determine that the withholding of such notice is
          in the interests of the Holders of the  Securities and coupons of such
          series; and provided further that in the ease of any default or breach
          of the  character  specified  in Section  501(4)  with  respect to the
          Securities and coupons of such series, no such notice to Holders shall
          be given until at least 60 days after the occurrence thereof.  For the
          purpose of this Section,  the term "default" means any event which is,
          or after  notice or lapse of time or both  would  become,  an Event of
          Default with respect to the Securities of such series.

               direction, consent, order, bond, debenture, note, coupon or other
               paper or document,  but the Trustee, in its discretion,  may make

               or  through  agents or  attorneys  and the  Trustee  shall not be
               responsible for any willful  misconduct or negligence on the part
               of any agent or attorney appointed with due care by it hereunder;

                    (8) the  Trustee  shall not be liable for any action  taken,

               provisions  of Sections  601 and 602,  the  Trustee  shall not be
               deemed to have  notice or  knowledge  of any  default or Event of
               Default  (other than under Section  501(1),  (2) or (3)) unless a
               Responsible  Officer  assigned  to and  working in the  Trustee's
               Corporate  Trust  Office has actual  knowledge  thereof or unless
               written  notice of any default or Event of Default is received by

               performance of any of its duties hereunder, or in the exercise of
               its rights or power,  if it shall  have  reasonable  grounds  for
               believing  that  repayment  of such funds or  adequate  indemnity
               against such risk or liability is not reasonably assured to it.

     Except  during  the  continuance  of  an  Event  of  Default,  the  Trustee
undertakes  to perform  only such duties as are  specifically  set forth in this
Indenture,  and no  implied  covenants  or  obligations  shall be read into this
Indenture against the Trustee.

               SECTION  603.  Not   Responsible  for  Recitals  or  Issuance  of
          Securities.  The  recitals  contained  herein  and in the  Securities,
          except the Trustee's certificate of authentication, and in any coupons
          shall be taken as the  statements  of the  Company,  and  neither  the
          Trustee nor any  Authenticating  Agent assumes any  responsibility for
          their  correctness.  The Trustee  makes no  representations  as to the
          validity or  sufficiency  of this  Indenture or of the  Securities  or
          coupons, except that the Trustee represents that it is duly authorized
          to execute and deliver this Indenture, authenticate the Securities and
          perform  its  obligations  hereunder.  Neither  the  Trustee  nor  any
          Authenticating  Agent shall be accountable  for the use or application
          by the Company of Securities or the proceeds thereof.

               SECTION 604. May Hold Securities.  The Trustee, any Paying Agent,
          Security  Registrar,  Authenticating  Agent or any other  agent of the
          Company, in its individual or any other capacity, may become the owner
          or pledgee of  Securities  and coupons  and,  subject to TIA  Sections
          310(b) and 311,  may  otherwise  deal with the  Company  with the same
          rights it would have if it were not Trustee,  Paying  Agent,  Security
          Registrar, Authenticating Agent or such other agent.

               SECTION  605.  Money Held in Trust.  Money held by the Trustee in
          trust  hereunder need not be segregated from other funds except to the
          extent  required by law. The Trustee  shall be under no liability  for
          interest on any money  received by it  hereunder  except as  otherwise
          agreed with the Company.

               SECTION 606. Compensation and Reimbursement. The Company agrees:

                    (1) to pay to the  Trustee  from  time  to  time  reasonable
               compensation  for all services  rendered by it  hereunder  (which
               compensation  shall not be  limited  by any  provision  of law in
               regard to the compensation of a trustee of in express trust);

                    (2)  except  as  otherwise  expressly  provided  herein,  to
               reimburse  each of the Trustee and any  predecessor  Trustee upon
               its  request  for  all  reasonable  expenses,  disbursements  and
               advances  incurred or made by the Trustee in accordance  with any
               provision   of   this   Indenture   (including   the   reasonable
               compensation and the expenses and disbursements of its agents and
               counsel), except any such expense, disbursement or advance as may
               be attributable to its negligence or willful misconduct; and

                    (3) to  indemnify  each of the Trustee  and any  predecessor
               Trustee for, and to hold it harmless against, any loss, liability
               or expense incurred without  negligence or willful  misconduct on
               its own part, arising out of or in connection with the acceptance
               or administration of the trust or trusts hereunder, including the
               costs and  expenses  of  defending  itself  against  any claim or
               liability in connection  with the exercise or  performance of any
               of its powers or duties hereunder.

     When the Trustee incurs expenses or renders  services in connection with an
Event of Default  specified in Section  501(6) or Section  501(7),  the expenses
(including  the  reasonable  charges  and  expenses  of  its  counsel)  and  the
compensation   for  the  services  are  intended  to   constitute   expenses  of
administration  under any applicable Federal or state bankruptcy,  insolvency or
other similar law.

     As security for the  performance  of the  obligations  of the Company under
this  Section,  the Trustee shall have a lien prior to the  Securities  upon all
property and funds held or  collected by the Trustee as such,  except funds held
in trust for the payment of  principal  of (or  premium,  if any) or interest on
particular Securities or any coupons.

     The  provisions  of this  Section  shall  survive the  termination  of this
Indenture.

               SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
          Interests. There shall at all times be a Trustee hereunder which shall
          be eligible to act as Trustee  under TIA Section  310(a)(1)  and shall
          have a combined capital and surplus of at least  $50,000,000.  If such
          corporation publishes reports of condition at least annually, pursuant
          to law or the requirements of Federal, State,  Territorial or District
          of Columbia supervising or examining authority,  then for the purposes
          of this Section,  the combined capital and surplus of such corporation
          shall be deemed to be its combined capital and surplus as set forth in
          its most recent report of condition so  published.  If at any time the
          Trustee shall cease to be eligible in accordance  with the  provisions
          of this Section,  it shall resign  immediately  in the manner and with
          the effect hereinafter specified in this Article.

               SECTION 608.  Resignation and Removal;  Appointment of Successor.
          (1) No  resignation  or removal of the Trustee and no appointment of a
          successor  Trustee  pursuant to this Article  shall  become  effective
          until the  acceptance  of  appointment  by the  successor  Trustee  in
          accordance with the applicable requirements of Section 609.

                    (2) The Trustee  may resign at any time with  respect to the
               Securities of one or more series by giving written notice thereof
               to the Company.  If an  instrument  of  acceptance by a successor
               Trustee  shall not have been  delivered to the Trustee  within 30
               days  after  the  giving  of  such  notice  of  resignation,  the
               resigning   Trustee   may   petition   any  court  of   competent
               jurisdiction for the appointment of a successor Trustee.

                    (3) The Trustee  may be removed at any time with  respect to
               the  Securities of any series by Act of the Holders of a majority
               in principal amount of the Outstanding  Securities of such series
               delivered to the Trustee and to the Company.

                    (4) If at any time:

                         (A)  the   Trustee   shall  fail  to  comply  with  the
                    provisions  of TIA  Section  310(b)  after  written  request
                    therefor by the  Company or by any Holder of a Security  who
                    has been a bona fide  Holder of a Security  for at least six
                    months;

                         (B)  the  Trustee  shall  cease  to be  eligible  under
                    Section 608 and shall fail to resign after  written  request
                    therefor by the  Company or by any Holder of a Security  who
                    has been a bona fide  Holder of a Security  for at least six
                    months; or

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove  the  Trustee  and  appoint  a  successor  Trustee  with  respect  to all
Securities,  or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others  similarly  situated,  petition any court of competent
jurisdiction  for the removal of the Trustee with respect to all  Securities and
the appointment of a successor Trustee or Trustees.

                    (5) If the  Trustee  shall  resign,  be  removed  or  become
               incapable of acting, or if a vacancy shall occur in the office of
               Trustee for any cause with  respect to the  Securities  of one or
               more series,  the Company,  by or pursuant to a Board Resolution,
               shall  promptly  appoint a  successor  Trustee or  Trustees  with
               respect  to the  Securities  of that or those  series  (it  being
               understood that any such successor  Trustee may be appointed with
               respect to the  Securities  of one or more or all of such  series
               and that at any time there shall be only one Trustee with respect
               to the Securities of any particular series).  If, within one year
               after  such   resignation,   removal  or  incapability,   or  the
               occurrence of such vacancy,  a successor  Trustee with respect to
               the  Securities  of any series  shall be  appointed by Act of the
               Holders  of a majority  in  principal  amount of the  Outstanding
               Securities  of  such  series  delivered  to the  Company  and the
               retiring  Trustee,  the  successor  Trustee so  appointed  shall,
               forthwith  upon its  acceptance of such  appointment,  become the
               successor  Trustee with respect to the  Securities of such series
               and to that extent supersede the successor  Trustee  appointed by
               the  Company.  If  no  successor  Trustee  with  respect  to  the
               Securities  of any  series  shall have been so  appointed  by the
               Company or the Holders of Securities and accepted  appointment in
               the manner hereinafter provided, any Holder of a Security who has
               been a bona fide Holder of a Security of such series for at least
               six months  may,  on behalf of himself  and all others  similarly
               situated,  petition any court of competent  jurisdiction  for the
               appointment of a successor  Trustee with respect to Securities of
               such series.

                    (6) The Company  shall give notice of each  resignation  and
               each removal of the Trustee with respect to the Securities of any
               series and each  appointment of a successor  Trustee with respect
               to the  Securities  of any  series  in the  manner  provided  for
               notices to the Holders of  Securities in Section 106. Each notice
               shall include the name of the  successor  Trustee with respect to
               the  Securities  of such series and the address of its  Corporate
               Trust Office.

               SECTION 609. Acceptance of Appointment by Successor.  (1) In case
          of the  appointment  hereunder of a successor  Trustee with respect to
          all   Securities,   every  such   successor   Trustee  shall  execute,
          acknowledge and deliver to the Company and to the retiring  Trustee an
          instrument  accepting such appointment,  and thereupon the resignation
          or removal of the retiring  Trustee  shall become  effective  and such
          successor Trustee, without any further act, deed or conveyance,  shall
          become  vested with all the rights,  powers,  trusts and duties of the
          retiring  Trustee;  but,  on request of the  Company or the  successor
          Trustee,  such retiring  Trustee  shall,  upon payment of its charges,
          execute  and  deliver an  instrument  transferring  to such  successor
          Trustee all the rights, powers and trusts of the retiring Trustee, and
          shall duly assign,  transfer and deliver to such successor Trustee all
          property and money held by such retiring  Trustee  hereunder,  subject
          nevertheless to its claim, if any, provided for in Section 606.

                    (2) In  case of the  appointment  hereunder  of a  successor
               Trustee  with respect to the  Securities  of one or more (but not
               all) series, the Company, the retiring Trustee and each successor
               Trustee  with  respect to the  Securities  of one or more  series
               shall  execute  and  deliver an  indenture  supplemental  hereto,
               pursuant to Article Nine hereof,  wherein each successor  Trustee
               shall accept such  appointment  and which (A) shall  contain such
               provisions  as shall be  necessary  or  desirable to transfer and
               confirm  to,  and to vest  in,  each  successor  Trustee  all the
               rights,  powers,  trusts and duties of the retiring  Trustee with
               respect to the  Securities  of that or those  series to which the
               appointment  of  such  successor  Trustee  relates,  (B)  if  the
               retiring  Trustee is not retiring with respect to all Securities,
               shall  contain such  provisions  as shall be deemed  necessary or
               desirable  to confirm  that all the  rights,  powers,  trusts and
               duties of the retiring  Trustee with respect to the Securities of
               that or those  series as to which  the  retiring  Trustee  is not
               retiring shall continue to be vested in the retiring Trustee, and
               (C)  shall  add  to or  change  any  of the  provisions  of  this
               Indenture as shall be necessary to provide for or facilitate  the
               administration  of the trusts hereunder by more than one Trustee,
               it being  understood that nothing herein or in such  supplemental
               indenture shall constitute such Trustees  co-trustees of the same
               trust and that each such  Trustee  shall be trustee of a trust or
               trusts  hereunder  separate  and  apart  from any trust or trusts
               hereunder  administered  by any other such Trustee;  and upon the
               execution  and  delivery  of  such  supplemental   indenture  the
               resignation  or  removal of the  retiring  Trustee  shall  become
               effective to the extent provided  therein and each such successor
               Trustee,  without  any further  act,  deed or  conveyance,  shall
               become vested with all the rights,  powers,  trusts and duties of
               the retiring  Trustee with respect to the  Securities  of that or
               those series to which the  appointment of such successor  Trustee
               relates; but, on request of the Company or any successor Trustee,
               such retiring Trustee shall duly assign,  transfer and deliver to
               such  successor  Trustee  all  property  and  money  held by such
               retiring Trustee hereunder with respect to the Securities of that
               or  those  series  to which  the  appointment  of such  successor
               Trustee relates.

                    (3) Upon request of any such successor Trustee,  the Company
               shall  execute  any  and  all  instruments  for  more  fully  and
               certainly vesting in and confirming to such successor Trustee all
               such rights,  powers and trusts  referred to in paragraph  (a) or
               (b) of this Section, as the case may be.

                    (4) No successor Trustee shall accept its appointment unless
               at the time of such  acceptance  such successor  Trustee shall be
               qualified and eligible under this Article.

               SECTION 610. Merger,  Conversion,  Consolidation or Succession to
          Business.  Any  corporation  into which the  Trustee  may be merged or
          converted  or with which it may be  consolidated,  or any  corporation
          resulting from any merger,  conversion or  consolidation  to which the
          Trustee  shall be a party,  or any  corporation  succeeding  to all or
          substantially  all of the  corporate  trust  business of the  Trustee,
          shall  be  the  successor  of the  Trustee  hereunder,  provided  such
          corporation  shall be  otherwise  qualified  and  eligible  under this
          Article,  without the  execution or filing of any paper or any further
          act on the part of any of the Parties  hereto.  In case any Securities
          or coupons shall have been  authenticated,  but not delivered,  by the
          Trustee  then in  office,  any  successor  by  merger,  conversion  or
          consolidation   to  such   authenticating   Trustee   may  adopt  such
          authentication  and deliver the Securities or coupons so authenticated
          with  the  same  effect  as  if  such  successor  Trustee  had  itself
          authenticated  such  Securities or coupons.  In case any Securities or
          coupons shall not have been authenticated by such predecessor Trustee,
          any  such  successor   Trustee  may   authenticate  and  deliver  such
          Securities  or  coupons,  in  either  its  own  name  or  that  of its
          predecessor  Trustee,  with the  full  force  and  effect  which  this
          Indenture  provides  for  the  certificate  of  authentication  of the
          Trustee.

               SECTION 611.  Appointment of  Authenticating  Agent. At ally time
          when any of the Securities remain Outstanding, the Trustee may appoint
          an  Authenticating  Agent or Agents with respect to one or more series
          of  Securities  which  shall be  authorized  to act on  behalf  of the
          Trustee  to  authenticate   Securities  of  such  series  issued  upon
          exchange,  registration of transfer or partial redemption or repayment
          thereof,  and  Securities  so  authenticated  shall be entitled to the
          benefits of this  Indenture and shall be valid and  obligatory for all
          purposes  as if  authenticated  by the  Trustee  hereunder.  Any  such
          appointment shall be evidenced by an instrument in writing signed by a
          Responsible  Officer of the Trustee,  a copy of which instrument shall
          be promptly  furnished to the Company.  Wherever  reference is made in
          this Indenture to the authentication and delivery of Securities by the
          Trustee or the Trustee's certificate of authentication, such reference
          shall be deemed to include  authentication  and  delivery on behalf of
          the  Trustee  by  an   Authenticating   Agent  and  a  certificate  of
          authentication  executed on behalf of the Trustee by an Authenticating
          Agent.  Each  Authenticating  Agent shall be acceptable to the Company
          and  shall  at all  times be a bank or trust  company  or  corporation
          organized and doing  business and in good  standing  wider the laws of
          the  United  States  of  America  or of any State or the  District  of
          Columbia,  authorized under such laws to act as Authenticating  Agent,
          having a combined capital and surplus of not less than $50,000,000 and
          subject to supervision or examination by Federal or State authorities.
          If such  Authenticating  Agent publishes reports of condition at least
          annually,  pursuant  to  law  or the  requirements  of  the  aforesaid
          supervising  or  examining  authority,  then for the  purposes of this
          Section, the combined capital and surplus of such Authenticating Agent
          shall be deemed to be its combined capital and surplus as set forth in
          its most recent report of condition so published.  In case at any time
          an Authenticating  Agent shall cease to be eligible in accordance with
          the provisions of this Section, such Authenticating Agent shall resign
          immediately  in the  manner  end with  the  effect  specified  in this
          Section.

     Any  corporation  into  which an  Authenticating  Agent  may be  merged  or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion or consolidation to which such Authenticating Agent
shall be a party,  or any  corporation  succeeding  to the  corporate  agency or
corporate  trust business of an  Authenticating  Agent,  shall continue to be an
Authenticating  Agent,  provided such  corporation  shall be otherwise  eligible
under this Section,  without the execution or filing of any paper or further act
on the part of the Trustee or the Authenticating Agent.

     An Authenticating Agent for any series of Securities may at any time resign
by giving  written  notice of  resignation to the Trustee for such series and to
the Company.  The Trustee for any series of Securities may at any time terminate
the agency of an Authenticating Agent by giving written notice of termination to
such  Authenticating  Agent and to the Company.  Upon receiving such a notice of
resignation  or  upon  such  a  termination,   or  in  case  at  any  time  such
Authenticating  Agent  shall  cease  to  be  eligible  in  accordance  with  the
provisions of this Section,  the Trustee for such series may appoint a successor
Authenticating  Agent  which shall be  acceptable  to the Company and shall give
notice of such  appointment  to all  Holders of  Securities  of the series  with
respect to which such Authenticating Agent will serve in the manner set forth in
Section  106.  Any  successor   Authenticating  Agent  upon  acceptance  of  its
appointment hereunder shall become vested with all the rights, powers and duties
of its  predecessor  hereunder,  with like effect as if  originally  named as an
Authenticating  Agent  herein.  No  successor   Authenticating  Agent  shall  be
appointed unless eligible under the provisions of this Section.

     The Company  agrees to pay to each  Authenticating  Agent from time to time
reasonable  compensation including  reimbursement of its reasonable expenses for
its services under this Section.

     If an  appointment  with respect to one or more series is made  pursuant to
this  Section,  the  Securities  of such series may have  endorsed  thereon,  in
addition  to or in lieu  of the  Trustee's  certificate  of  authentication,  an
alternate certificate of authentication substantially in the following form:

     This is one of the Securities of the series designated  therein referred to
in the within-mentioned Indenture.

                                  ARTICLE EIGHT

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

               SECTION  801.  Consolidations  and  Mergers of Company and Sales,
          Leases and Conveyances  Permitted Subject to Certain  Conditions.  The
          Company  may  consolidate  with,  or  sell,  lease  or  convey  all or
          substantially  all of its  assets  to, or merge with or into any other
          corporation,  provided  that in any such case,  (1) either the Company
          shall be the  continuing  corporation,  or the  successor  corporation
          shall be a corporation  organized  and existing  under the laws of the
          United States or a State thereof and such successor  corporation shall
          expressly assume the due and punctual payment of the principal of (and
          premium,  if any) and any interest  (including all Additional Amounts,
          if any,  payable  pursuant to Section 1011) on all of the  Securities,
          according to their tenor,  and the due and  punctual  performance  and
          observance of all of the covenants and conditions of this Indenture to
          be performed by the Company by supplemental indenture,  complying with
          Article  Nine  hereof,  satisfactory  to  the  Trustee,  executed  and
          delivered to the Trustee by such corporation and (2) immediately after
          giving effect to such transaction and treating any indebtedness  which
          becomes an  obligation  of the Company or any  Subsidiary  as a result
          thereof as having been  incurred by the Company or such  Subsidiary at
          the time of such transaction, no Event of Default, and no event which,
          after notice or the lapse of time,  or both,  would become an Event of
          Default, shall have occurred and be continuing.

               SECTION 802. Rights and Duties of Successor Corporation.  In case
          of any such consolidation,  merger, sale, lease or conveyance and upon
          any such  assumption  by the  successor  corporation,  such  successor
          corporation shall succeed to and be substituted for the Company,  with
          the same  effect  as if it had been  named  herein as the party of the
          first part, and the predecessor corporation,  except in the event of a
          lease,  shall  be  relieved  of  any  further  obligation  under  this
          Indenture and the Securities. Such successor corporation thereupon may
          cause to be  signed,  and may  issue  either in its own name or in the
          name of the Company,  any or all of the Securities  issuable hereunder
          which  theretofore  shall not have  been  signed  by the  Company  and
          delivered  to the  Trustee;  and,  upon the  order  of such  successor
          corporation,  instead of the  Company,  and  subject to all the terms,
          conditions and limitations in this Indenture  prescribed,  the Trustee
          shall  authenticate  and shall deliver any Securities which previously
          shall have been signed and delivered by the officers of the Company to
          the  Trustee  for  authentication,   and  any  Securities  which  such
          successor  corporation   thereafter  shall  cause  to  be  signed  and
          delivered  to the  Trustee for that  purpose.  All the  Securities  so
          issued  shall in all  respects  have the same legal  rank and  benefit
          under this  Indenture  as the  Securities  theretofore  or  thereafter
          issued in accordance with the terms of this Indenture as though all of
          such Securities had been issued at the date of the execution hereof.

     In case of any such consolidation,  merger, sale, lease or conveyance, such
changes  in  phraseology  and  form  (but not in  substance)  may be made in the
Securities thereafter to be issued as may be appropriate.

               SECTION 803.  Officers'  Certificate and Opinion of Counsel.  Any
          consolidation,  merger,  sale,  lease or  conveyance  permitted  under
          Section 801 is also subject to the condition that the Trustee  receive
          an Officers'  Certificate and an Opinion of Counsel to the effect that
          any such  consolidation,  merger,  sale, lease or conveyance,  and the
          assumption by any successor corporation,  complies with the provisions
          of this Article and that all conditions  precedent herein provided for
          relating to such transaction have been complied with.

                             SUPPLEMENTAL INDENTURES

               SECTION 901. Supplemental  Indentures without Consent of Holders.
          Without  the  consent of any Holders of  Securities  or  coupons,  the
          Company, when authorized by or pursuant to a Board Resolution, and the
          Trustee, at any time and from time to time, may enter into one or more
          indentures  supplemental  hereto, in form satisfactory to the Trustee,
          for any of the following purposes:

                    (1) to  evidence  the  succession  of another  Person to the
               Company and the assumption by any such successor of the covenants
               of the Company herein and in the Securities contained;

                    (2) to add to the  covenants  of the Company for the benefit
               of the  Holders of all or any series of  Securities  (and if such
               covenants  are to be for the  benefit  of less than all series of
               Securities,  stating  that such  covenants  are  expressly  being
               included  solely for the benefit of such  series) or to surrender
               any right or power herein conferred upon the Company;

                    (3) to add any additional  Events of Default for the benefit
               of the  Holders of all or any series of  Securities  (and if such
               Events  of  Default  are to be for the  benefit  of less than all
               series of  Securities,  stating  that such  Events of Default are
               expressly  being included solely for the benefit of such series);
               provided,  however, that in respect of any such additional Events
               of  Default  such  supplemental   indenture  may  provide  for  a
               particular  period of grace after  default  (which  period may be
               shorter  or  longer  than  that  allowed  in the  case  of  other
               defaults) or may provide for an immediate  enforcement  upon such
               default or may limit the  remedies  available to the Trustee upon
               such  default or may limit the right of the Holders of a majority
               in  aggregate  principal  amount  of  that  or  those  series  of
               Securities  to which such  additional  Events of Default apply to
               waive such default;

                    (4) to add to or  change  any  of  the  provisions  of  this
               Indenture to provide that Bearer Securities may be registrable as
               to  principal,  to change or eliminate  any  restrictions  on the
               payment of  principal  of or any  premium or  interest  on Bearer
               Securities,  to permit Bearer Securities to be issued in exchange
               for  Registered  Securities,  to permit  Bearer  Securities to be
               issued in  exchange  for Bearer  Securities  of other  authorized
               denominations   or  to  permit  or  facilitate  the  issuance  of
               Securities in uncertificated  form, provided that any such action
               shall not  adversely  affect  the  interests  of the  Holders  of
               Securities  of any series or any related  coupons in any material
               respect;

                    (5) to change or  eliminate  any of the  provisions  of this
               Indenture,  provided  that any such change or  elimination  shall
               become  effective  only when there is no Security  Outstanding of
               any series  created prior to the  execution of such  supplemental
               indenture which is entitled to the benefit of such provisions;

                    (6) to secure the Securities;

                    (7) to  establish  the form or terms  of  Securities  of any
               series and any related  coupons as  permitted by Sections 201 and
               301,   including  the  provisions  and  procedures   relating  to
               Securities convertible into Common Shares or Preferred Shares, as
               the case may be;

                    (8)  to  evidence   and  provide  for  the   acceptance   of
               appointment  hereunder by a successor Trustee with respect to the
               Securities  of one or more  series and to add to or change any of
               the provisions of this Indenture as shall be necessary to provide
               for or facilitate the  administration  of the trusts hereunder by
               more than one Trustee;

                    (9) to cure any  ambiguity,  to  correct or  supplement  any
               provision herein which may be defective or inconsistent  with any
               other  provision  herein,  or to make any other  provisions  with
               respect to  matters or  questions  arising  under this  Indenture
               which  shall  not be  inconsistent  with the  provisions  of this
               Indenture,  provided such provisions  shall not adversely  affect
               the  interests of the Holders of  Securities of any series or any
               related coupons in any material respect; or

                    (10) to supplement  any of the  provisions of this Indenture
               to such extent as shall be necessary to permit or facilitate  the
               defeasance and discharge of any series of Securities  pursuant to
               Sections 401, 1402 and 1403;  provided that any such action shall
               not  adversely  affect the interests of the Holders of Securities
               of such  series and any  related  coupons or any other  series of
               Securities in any material respect.

               SECTION  902.  Supplemental  Indentures  with Consent of Holders.
          With the  consent  of the  Holders  of not  less  than a  majority  in
          principal  amount  of all  Outstanding  Securities  affected  by  such
          supplemental  indenture,  by  Act of  said  Holders  delivered  to the
          Company and the Trustee,  the Company,  when authorized by or pursuant
          to a Board Resolution,  and the Trustee may enter into an indenture or
          indentures   supplemental   hereto  for  the  purpose  of  adding  any
          provisions  to or  changing  in any manner or  eliminating  any of the
          provisions of this  Indenture or of modifying in any manner the rights
          of the  Holders  of  Securities  and any  related  coupons  under this
          Indenture;  provided,  however,  that no such  supplemental  indenture
          shall,  without the consent of the Holder of each Outstanding Security
          affected thereby:

                    (1) change  the  Stated  Maturity  of the  principal  of (or
               premium,  if  any,  on) or any  installment  of  principal  of or
               interest on, any Security; or reduce the principal amount thereof
               or the rate or amount of interest  thereon or Additional  Amounts
               payable in  respect  thereof,  or any  premium  payable  upon the
               redemption  thereof,  or change any  obligation of the Company to
               pay  Additional  Amounts  pursuant  to  Section  1008  (except as
               contemplated by Section 801(1) and permitted by Section  901(1)),
               or  reduce  the  amount of the  principal  of an  Original  Issue
               Discount   Security   that  would  be  due  and  payable  upon  a
               declaration of acceleration of the Maturity  thereof  pursuant to
               Section 502 or the amount thereof provable in bankruptcy pursuant
               to Section 504, or adversely affect any right of repayment at the
               option of the  Holder  of any  Security,  or change  any Place of
               Payment where,  or the currency or  currencies,  currency unit or
               units or composite  currency or currencies in which, any Security
               or any premium or the interest thereon is payable,  or impair the
               right to institute  suit for the  enforcement of any such payment
               on or after  the  Stated  Maturity  thereof  (or,  in the case of
               redemption or repayment at the option of the Holder,  on or after
               the Redemption Date or the Repayment Date, as the case may be);

                    (2)  reduce  the  percentage  in  principal  amount  of  the
               Outstanding  Securities  of any  series,  the  consent  of  whose
               Holders is required for any such supplemental  indenture,  or the
               consent of whose  Holders is required for any waiver with respect
               to such series (or  compliance  with certain  provisions  of this
               Indenture or certain defaults  hereunder and their  consequences)
               provided for in this  Indenture,  or reduce the  requirements  of
               Section 1504 for quorum or voting; or

                    (3) modify any of the  provisions of this  Section,  Section
               513 or Section 1012,  except to increase the required  percentage
               to effect such action or to provide that certain other provisions
               of this  Indenture  cannot  be  modified  or waived  without  the
               consent  of the  Holder  of each  Outstanding  Security  affected
               thereby.

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

     A supplemental  indenture which changes or eliminates any covenant or other
provision of this  Indenture  which has expressly  been included  solely for the
benefit of one or more  particular  series of Securities,  or which modifies the
rights of the Holders of Securities of such series with respect to such covenant
or other  provision,  shall be  deemed  not to  affect  the  rights  under  this
Indenture of the Holders of Securities of any other series.

               SECTION 903. Execution of Supplemental Indentures.  In executing,
          or  accepting  the  additional  trusts  created  by, any  supplemental
          indenture permitted by this Article or the modification thereby of the
          trusts  created by this  Indenture,  the Trustee  shall be entitled to
          receive,  and shall be fully  protected in relying upon, an Opinion of
          Counsel stating that the execution of such  supplemental  indenture is
          authorized or permitted by this Indenture.  The Trustee may, but shall
          not be obligated to, enter into any such supplemental  indenture which
          affects the  Trustee's  own rights,  duties or  immunities  under this
          Indenture or otherwise.

               SECTION  904.  Effect  of  Supplemental   Indentures.   Upon  the
          execution  of any  supplemental  indenture  under this  Article,  this
          Indenture  shall  be  modified  in  accordance  therewith,   and  such
          supplemental  indenture  shall form a part of this  Indenture  for all
          purposes;  and every Holder of  Securities  theretofore  or thereafter
          authenticated and delivered  hereunder and of any coupon  appertaining
          thereto shall be bound thereby.

               SECTION  905.   Conformity   with  Trust   Indenture  Act.  Every
          supplemental indenture executed pursuant to this Article shall conform
          to the requirements of the Trust Indenture Act as then in effect.

               SECTION 906. Reference in Securities to Supplemental  Indentures.
          Securities  of  any  series  authenticated  and  delivered  after  the
          execution of any supplemental  indenture pursuant to this Article may,
          and  shall,  if  required  by the  Trustee,  bear a  notation  in form
          approved  by  the  Trustee  as to any  matter  provided  for  in  such
          supplemental  indenture.  If  the  Company  shall  so  determine,  new
          Securities of any series so modified as to conform,  in the opinion of
          the Trustee and the Company, to any such supplemental indenture may be
          prepared and executed by the Company and  authenticated  and delivered
          by the Trustee in exchange for Outstanding Securities of such series.

                                   ARTICLE TEN

                                    COVENANTS

               SECTION 1001. Payment of Principal, Premium, if any, Interest and
          Additional  Amounts.  The Company covenants and agrees for the benefit
          of the  Holders  of each  series of  Securities  that it will duly and
          punctually pay the principal of (and premium,  if any) and interest on
          and any  Additional  Amounts  payable in respect of the  Securities of
          that series in accordance with the terms of such series of Securities,
          any coupons appertaining thereto and this Indenture.  Unless otherwise
          specified as contemplated by Section 301 with respect to any series of
          Securities,  any interest due on and any Additional Amounts payable in
          respect  of  Bearer  Securities  on or  before  Maturity,  other  than
          Additional  Amounts,  if any,  payable as provided in Section  1011 in
          respect of  principal  of (or  premium,  if any,  on) such a Security,
          shall be payable only upon  presentation  and surrender of the several
          coupons for such interest  installments  as are  evidenced  thereby as
          they  severally  mature.  Unless  otherwise  specified with respect to
          Securities of any series pursuant to Section 301, at the option of the
          Company,  all  payments  of  principal  may be  paid by  check  to the
          registered Holder of the Registered  Security or other person entitled
          thereto against surrender of such Security.

               SECTION 1002. Maintenance of Office or Agency. If Securities of a
          series are issuable only as Registered  Securities,  the Company shall
          maintain  in each Place of Payment  for any  series of  Securities  an
          office or agency where  Securities  of that series may be presented or
          surrendered for payment or conversion, where Securities of that series
          may be surrendered for  registration of transfer or exchange and where
          notices  and  demands  to or  upon  the  Company  in  respect  of  the
          Securities  of that  series  and  this  Indenture  may be  served.  If
          Securities of a series are issuable as Bearer Securities,  the Company
          will  maintain:  (A) in the Borough of  Manhattan,  New York City,  an
          office or agency where any Registered Securities of that series may be
          presented  or  surrendered  for  payment  or  conversion,   where  any
          Registered   Securities  of  that  series  may  be   surrendered   for
          registration  of  transfer,  where  Securities  of that  series may be
          surrendered  for  exchange,  where  notices and demands to or upon the
          Company in respect of the Securities of that series and this Indenture
          may be served and where Bearer  Securities  of that series and related
          coupons may be presented or  surrendered  for payment or conversion in
          the  circumstances  described  in the  following  paragraph  (and  not
          otherwise); (B) subject to any laws or regulations applicable thereto,
          in a Place of Payment  for that  series  which is located  outside the
          United States, an office or agency where Securities of that series and
          related   coupons  may  be  presented  and   surrendered  for  payment
          (including  payment of any Additional Amounts payable on Securities of
          that  series  pursuant  to  Section  1008)  or  conversion;  provided,
          however,  that if the  Securities  of that  series  are  listed on the
          Luxembourg  Stock Exchange or any other stock exchange located outside
          the United  States  and such  stock  exchange  shall so  require,  the
          Company will maintain a Paying Agent for the Securities of that series
          in  Luxembourg or any other  required city located  outside the United
          States,  as the case may be, so long as the  Securities of that series
          are  listed  on  such  exchange;  and  (C)  subject  to  any  laws  or
          regulations  applicable thereto, in a Place of Payment for that series
          located  outside  the  United  States an  office  or agency  where any
          Registered   Securities  of  that  series  may  be   surrendered   for
          registration  of  transfer,  where  Securities  of that  series may be
          surrendered  for exchange and where notices and demands to or upon the
          Company in respect of the Securities of that series and this Indenture
          may be served.  The  Company  will give prompt  written  notice to the
          Trustee of the location,  and any change in the location, of each such
          office or agency.  If at any time the  Company  shall fail to maintain
          any such  required  office  or  agency or shall  fail to  furnish  the
          Trustee  with the address  thereof,  such  presentations,  surrenders,
          notices  and  demands  may be made or  served at the  Corporate  Trust
          Office of the Trustee,  except that Bearer  Securities  of that series
          and the related  coupons may be presented and  surrendered for payment
          (including  payment  of  any  Additional  Amounts  payable  on  Bearer
          Securities  of that series  pursuant to Section 1008) or conversion at
          the offices  specified in the Security,  in London,  England,  and the
          Company  hereby  appoints  the  same  as its  agent  to  receive  such
          respective  presentations,  surrenders,  notices and demands,  and the
          Company  hereby  appoints  the  Trustee  its agent to receive all such
          presentations, surrenders, notices and demands.

     Unless  otherwise  specified  with  respect to any  Securities  pursuant to
Section  301, no payment of  principal,  premium or  interest  on or  Additional
Amounts in respect of Bearer Securities shall be made at any office or agency of
the Company in the United States or by check mailed to any address in the United
States or by transfer to an account maintained with a bank located in the United
States;  provided,  however,  that, if the Securities of a series are payable in
Dollars,  payment of  principal  of and any premium  and  interest on any Bearer
Security  (including any Additional Amounts payable on Securities of such series
pursuant to Section 1008) shall be made at the office of the designated agent of
the Company's  Paying Agent in the Borough of Manhattan,  New York City, if (but
only if)  payment  in  Dollars of the full  amount of such  principal,  premium,
interest or Additional  Amounts,  as the case may be, at all offices or agencies
outside  the  United  States  maintained  for  the  purpose  by the  Company  in
accordance with this Indenture,  is illegal or effectively precluded by exchange
controls or other similar restrictions.

     The Company may from time to time  designate  one or more other  offices or
agencies  where  the  Securities  of one or  more  series  may be  presented  or
surrendered  for any or all of such purposes,  and may from time to time rescind
such  designations;  provided,  however,  that no such designation or rescission
shall in any manner  relieve the Company of its obligation to maintain an office
or agency in accordance with the  requirements set forth above for Securities of
any series for such purposes. The Company will give prompt written notice to the
Trustee of any such  designation or rescission and of any change in the location
of any such other office or agency.  Unless otherwise  specified with respect to
any  Securities  pursuant to Section 301 with respect to a series of Securities,
the  Company  hereby  designates  as a Place  of  Payment  for  each  series  of
Securities the office or agency of the Company in the Borough of Manhattan,  New
York City, and initially  appoints the Trustee at its Corporate  Trust Office as
Paying Agent and as its agent to receive all such presentations, surrenders, and
notices and demands.

     Unless  otherwise  specified  with  respect to any  Securities  pursuant to
Section 301, if and so long as the Securities of any series (i) are  denominated
in a Foreign Currency or (ii) may be payable in a Foreign  Currency,  or so long
as it is required under any other  provision of the Indenture,  then the Company
will maintain with respect to each such series of Securities, or as so required,
at least one exchange rate agent.

               SECTION 1003. Money for Securities  Payments to Be Held in Trust.
          If the  Company  shall at any time act as its own  Paying  Agent  with
          respect to any series of any  Securities and any related  coupons,  it
          will, on or before each due date of the principal of (and premium,  if
          any), or interest on or  Additional  Amounts in respect of, any of the
          Securities of that series, segregate and hold in trust for the benefit
          of the Persons  entitled there to a sum in the currency or currencies,
          currency  unit or units or composite  currency or  currencies in which
          the  Securities  of such  series  are  payable  (except  as  otherwise
          specified  pursuant to Section 301 for the  Securities of such series)
          sufficient to pay the principal  (and premium,  if any) or interest or
          Additional  Amounts so  becoming  due until such sums shall be paid to
          such Persons or  otherwise  disposed of as herein  provided,  and will
          promptly notify the Trustee of its action or failure so to act.

     Whenever the Company shall have one or more Paying Agents for any series of
Securities  and any  related  coupons,  it  will,  before  each  due date of the
principal of (and  premium,  if any),  or interest on or  Additional  Amounts in
respect of, any Securities of that series, deposit with a Paying Agent a sum (in
the currency or  currencies,  currency  unit or units or  composite  currency or
currencies described in the preceding paragraph) sufficient to pay the principal
(and premium,  if any) or interest or Additional  Amounts, so becoming due, such
sum to be  held in  trust  for  the  benefit  of the  Persons  entitled  to such
principal,  premium or interest or  Additional  Amounts and (unless  such Paying
Agent is the Trustee) the Company will promptly notify the Trustee of its action
or failure so to act.

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

                    (1) hold all sums held by it for the payment of principal of
               (and  premium,  if any) or interest on  Securities  or Additional
               Amounts in trust for the benefit of the Persons  entitled thereto
               until  such  sums  shall  be paid to such  Persons  or  otherwise
               disposed of as herein provided;

                    (2) give the  Trustee  notice of any  default by the Company
               (or any other obligor upon the  Securities)  in the making of any
               such payment of principal  (and  premium,  if any) or interest or
               Additional Amounts; and

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

     The Company may at any time, for the purpose of obtaining the  satisfaction
and  discharge of this  Indenture or for any other  purpose,  pay, or by Company
Order  direct any Paying  Agent to pay, to the Trustee all sums held in trust by
the Company or such Paying  Agent,  such sums to be held by the Trustee upon the
same  trusts as those  upon  which  such sums were held by the  Company  or such
Paying Agent;  and,  upon such payment by any Paying Agent to the Trustee,  such
Paying Agent shall be released from all further  Liability  with respect to such
sums.

     Except as otherwise  provided in the  Securities  of any series,  any money
deposited with the Trustee or any Paying Agent, or then held by the Company,  in
trust for the payment of the principal of (and premium,  if any) or interest on,
or any  Additional  Amounts  in  respect  of,  any  Security  of any  series and
remaining  unclaimed for two years after such principal  (and premium,  if any),
interest of Additional  Amounts have become due and payable shall be paid to the
Company  upon  Company  Request  or (if  then  held  by the  Company)  shall  be
discharged from such trust; and the Holder of such Security shall thereafter, as
an  unsecured  general  creditor,  look only to the  Company for payment of such
principal of (and premium,  if any) or interest on, or any Additional Amounts in
respect of, any Security,  without  interest  thereon,  and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as trustee  thereof,  shall thereupon cease;  provided,  however,
that the Trustee or such Paying  Agent,  before being  required to make any such
repayment,  may at the expense of the Company cause to be published  once, in an
Authorized Newspaper, notice that such money remains unclaimed and that, after a
date  specified  therein,  which shall not be less than 30 days from the date of
such  publication,  any unclaimed  balance of such money then  remaining will be
repaid to the Company.

               SECTION 1004.  Existence.  Subject to Article Eight,  the Company
          will do or cause to be done all things  necessary to preserve and keep
          in full  force  and  effect  its  existence,  rights  and  franchises;
          provided,  however, that the Company shall not be required to preserve
          any right or franchise if the Board of Trust Managers shall  determine
          that the preservation thereof is no longer desirable in the conduct of
          the business of the Company.

               SECTION 1005. Payment of Taxes and Other Claims. The Company will
          pay or  discharge or cause to be paid or  discharged,  before the same
          shall become delinquent,  (1) all taxes,  assessments and governmental
          charges  levied  or  imposed  upon it or any  Subsidiary  or upon  the
          income, profits or property of the Company or any Subsidiary,  and (2)
          all lawful claims for labor,  materials and supplies which, if unpaid,
          might by law  become a lien upon the  property  of the  Company or any
          Subsidiary;  provided, however, that the Company shall not be required
          to pay or  discharge or cause to be paid or  discharged  any such tax,
          assessment, charge or claim whose amount, applicability or validity is
          being contested in good faith.

               SECTION 1006. Provision of Financial Information.  Whether or not
          the  Company  is  subject  to  Section  13 or 15(d) of the  Securities
          Exchange Act of 1934,  the Company  will  prepare the annual  reports,
          quarterly  reports and other  documents  within 15 days of each of the
          respective dates by which the Company would have been required to file
          with the Commission  pursuant to such Section 13 or 15(d) and will (i)
          transmit by mail to all Holders,  as their names and addresses  appear
          in the Security  Register,  without cost to such Holders copies of the
          annual  reports,  quarterly  reports  and  other  documents  which the
          Company would have been required to file with the Commission  pursuant
          to Section 13 or 15(d) of the  Securities  Exchange Act of 1934 if the
          Company  were  subject to such  Sections,  (ii) file with the  Trustee
          copies of the annual  reports,  quarterly  reports and other documents
          which the Company would have been required to file with the Commission
          pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934
          if the Company were subject to such  Sections and (iii)  promptly upon
          written  request and payment of the reasonable cost of duplication and
          delivery, supply copies of such documents to any prospective Holder.

               SECTION  1007.  Statement  as to  Compliance.  The  Company  will
          deliver to the  Trustee,  within 120 days after the end of each fiscal
          year,  a brief  certificate  from  the  principal  executive  officer,
          principal financial officer or principal  accounting officer as to his

          covenants under this Indenture and, in the event of any noncompliance,
          specifying such  noncompliance and the nature and status thereof.  For
          purposes of this Section  1007,  such  compliance  shall be determined
          without  regard to any period of grace or  requirement of notice under
          this Indenture.

               SECTION 1008.  Additional  Amounts. If any Securities of a series
          provide for the payment of Additional Amounts, the Company will pay to
          the Holder of any  Security of such series or any coupon  appertaining
          thereto  Additional  Amounts as may be  specified as  contemplated  by
          Section 301.  Whenever in this  Indenture  there is mentioned,  in any
          context  except in the case of  Section  502(1),  the  payment  of the
          principal  of or any  premium or  interest  on, or in respect  of, any
          Security  of any series or payment  of any  related  coupon or the net
          proceeds  received  on the sale or  exchange  of any  Security  of any
          series, such mention shall be deemed to include mention of the payment
          of Additional Amounts provided by the terms of such series established
          pursuant  to  Section  301  to  the  extent  that,  in  such  context,
          Additional  Amounts are,  were or would be payable in respect  thereof
          pursuant  to  such  terms  and  express  mention  of  the  payment  of
          Additional  Amounts (if applicable) in any provisions hereof shall not
          be  construed  as  excluding  Additional  Amounts in those  provisions
          hereof where such express mention is not made.

     Except as  otherwise  specified  as  contemplated  by Section  301,  if the
Securities of a series provide for the payment of Additional  Amounts,  at least
10 days prior to the first Interest  Payment Date with respect to that series of
Securities  (or if the Securities of that series will not bear interest prior to
Maturity,  the first day on which a payment  of  principal  and any  premium  is
made),  and at least 10 days prior to each date of payment of principal  and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certificate, the Company will furnish the
Trustee and the Company's principal Paying Agent or Paying Agents, if other than
the Trustee,  with an  Officers'  Certificate  instructing  the Trustee and such
Paying  Agent or Paying  Agents  whether  such  payment of  principal of and any
premium or interest on the Securities of that series shall be made to Holders of
Securities  of that  series or any  related  coupons  who are not United  States
persons without  withholding  for or on account of any tax,  assessment or other
governmental  charge  described  in the  Securities  of the series.  If any such
withholding shall be required,  then such Officers' Certificate shall specify by
country the  amount,  if any,  required to be withheld on such  payments to such
Holders of Securities of that series or related coupons and the Company will pay
to the Trustee or such Paying Agent the Additional Amounts required by the terms
of such  Securities.  In the event that the Trustee or any Paying Agent,  as the
case may be,  shall not so receive  the  above-mentioned  certificate,  then the
Trustee  or such  Paying  Agent  shall be  entitled  (i) to assume  that no such
withholding or deduction is required with respect to any payment of principal or
interest with respect to any Securities of a series or related  coupons until it
shall  have  received  a  certificate  advising  otherwise  and (ii) to make all
payments of principal and interest with respect to the Securities of a series or
related coupons without  withholding or deductions until otherwise advised.  The
Company covenants to indemnify the Trustee and any Paying Agent for, and to hold
them  harmless  against,  any loss,  liability  or expense  reasonably  incurred
without  negligence  or bad faith on their part arising out of or in  connection
with  actions  taken or omitted by any of them or in reliance  on any  Officers'
Certificate  furnished  pursuant to this Section or in reliance on the Company's
not furnishing such an Officers' Certificate.

               SECTION 1009. Waiver of Certain  Covenants.  The Company may omit
          in any  particular  instance  to comply  with any term,  provision  or
          condition set forth in Sections 1004 to 1009, inclusive,  if before or
          after the time for such  compliance the Holders of at least a majority
          in principal amount of all outstanding  Securities of such series,  by
          Act of such Holders,  either waive such compliance in such instance or
          generally  waive  compliance  with such covenant or condition,  but no
          such  waiver  shall  extend to or affect such  covenant  or  condition
          except to the extent so expressly waived, and, until such waiver shall
          become effective, the obligations of the Company and the duties of the
          Trustee  in respect of any such term,  provision  or  condition  shall
          remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

               SECTION 1101. Applicability of Article.  Securities of any series
          which are redeemable  before their Stated Maturity shall be redeemable
          in accordance  with their terms and (except as otherwise  specified as
          contemplated   by  Section  301  for  Securities  of  any  series)  in
          accordance with this Article.

               SECTION 1102. Election to Redeem; Notice to Trustee. The election
          of the  Company  to redeem any  Securities  shall be  evidenced  by or
          pursuant  to a Board  Resolution.  In case  of any  redemption  at the
          election  of the  Company  of less than all of the  Securities  of any
          series, the Company shall, at least 45 days prior to the giving of the
          notice of redemption in Section 1104 (unless a shorter notice shall be
          satisfactory  to the  Trustee),  notify the Trustee in writing of such
          Redemption  Date and of the  principal  amount of  Securities  of such
          series to be redeemed.  In the case of any  redemption  of  Securities
          prior to the expiration of any restriction on such redemption provided
          in the terms of such  Securities or elsewhere in this  Indenture,  the
          Company  shall  furnish the  Trustee  with all  Officers'  Certificate
          evidencing compliance with such restriction.

               SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.
          If less than all the  Securities  of any series issued on the same day
          with the same terms are to be redeemed,  the particular  Securities to
          be  redeemed  shall be  selected  not more  than 60 days  prior to the
          Redemption  Date by the Trustee,  from the  Outstanding  Securities of
          such  series  issued on such date with the same  terms not  previously
          called for  redemption,  by such method as the Trustee shall deem fair
          and  appropriate and which may provide for the election for redemption
          of  portions  (equal  to  the  minimum  authorized   denomination  for
          Securities  of that series or any  integral  multiple  thereof) of the
          principal amount of Securities of such series of a denomination larger
          than  the  minimum  authorized  denomination  for  Securities  of that
          series.

     The Trustee shall  promptly  notify the Company and the Security  Registrar
(if other than itself) in writing of the Securities selected for redemption and,
in the case of any  Securities  selected for partial  redemption,  the principal
amount thereof to be redeemed.

     For all purposes of this Indenture,  unless the context otherwise requires,
all  provisions  relating to the redemption of Securities  shall relate,  in the
case of any Security  redeemed or to be redeemed only in part, to the portion of
the principal amount of such Security which has been or is to be redeemed.

               SECTION 1104. Notice of Redemption. Notice of redemption shall be
          given in the manner provided in Section 106, not less than 30 days nor
          more  than 60 days  prior to the  Redemption  Date,  unless a  shorter
          period is specified by the terms of such series  established  pursuant
          to Section  301,  to each Holder of  Securities  to be  redeemed,  but
          failure  to give such  notice in the  manner  herein  provided  to the
          Holder of any  Security  designated  for  redemption  as a whole or in
          part, or any defect in the notice to any such Holder, shall not affect
          the validity of the  proceedings  for the redemption of any other such
          Security or portion thereof.

     Any notice that is mailed to the Holders of  Registered  Securities  in the
manner herein provided shall be  conclusively  presumed to have been duly given,
whether or not the Holder receives the notice.

               All notices of redemption shall state:

                    (1) the Redemption Date;

                    (2) the Redemption Price, accrued interest to the Redemption
               Date payable as provided in Section 1106, if any, and  Additional
               Amounts, if any;

                    (3) if less than all  Outstanding  Securities  of any series
               are to be  redeemed,  the  identification  (and,  in the  case of
               partial  redemption,  the  principal  amount)  of the  particular
               Security or Securities to be redeemed;

                    (4) in case any Security is to be redeemed in part only, the
               notice  which  relates to such  Security  shall state that on and
               after the Redemption  Date, upon surrender of such Security,  the
               holder  will  receive,  without  a  charge,  a  new  Security  or
               Securities of authorized  denominations  for the principal amount
               thereof remaining unredeemed;

                    (5) that on the  Redemption  Date the  Redemption  Price and
               accrued  interest to the  Redemption  Date payable as provided in
               Section  1106, if any, will become due and payable upon each such
               Security,  or  the  Portion  thereof,  to  be  redeemed  and,  if
               applicable,  that  interest  thereon shall cease to accrue on and
               after said date;

                    (6) the Place or Places of Payment  where  such  Securities,
               together  in the  case of  Bearer  Securities  with  all  coupons
               appertaining thereto, if any, maturing after the Redemption Date,
               are to be  surrendered  for payment of the  Redemption  Price and
               accrued interest, if any, or for conversion;

                    (7) that the  redemption  is for a sinking  fund, if such is
               the case;

                    (8) that, unless otherwise specified in such notice,  Bearer
               Securities of any series, if any, surrendered for redemption must
               be  accompanied  by all coupons  maturing  subsequent to the date
               fixed for  redemption or the amount of any such missing coupon or
               coupons  will be  deducted  from  the  Redemption  Price,  unless
               security or indemnity  satisfactory  to the Company,  the Trustee
               for such series and any Paying Agent is furnished;

                    (9) if Bearer  Securities  of any series are to be  redeemed
               and  any  Registered  Securities  of  such  series  are not to be
               redeemed,  and if such Bearer  Securities  may be  exchanged  for
               Registered   Securities   not  subject  to   redemption  on  this
               Redemption  Date pursuant to Section 305 or  otherwise,  the last
               date, as determined by the Company,  on which such  exchanges may
               be made;

                    (10) the CUSIP number of such Security, if any; and

                    (11) if applicable,  that a Holder of Securities who desires
               to  convert   Securities   for   redemption   must   satisfy  the
               requirements  for conversion  contained in such  Securities,  the
               then  existing  conversion  price or rate,  and the date and time
               when the option to convert shall expire.

     Notice of redemption  of  Securities  to be redeemed  shall be given by the
Company  or, at the  Company's  request,  by the  Trustee in the name and at the
expense of the Company.

               SECTION 1105.  Deposit of  Redemption  Price.  On any  Redemption
          Date,  the  Company  shall  deposit  with the Trustee or with a Paying
          Agent (or, if the Company is acting as its own Paying Agent,  which it
          may not do in the case of a sinking fund payment under Article Twelve,
          segregate  and hold in trust as provided in Section 1003) an amount of
          money  in the  currency  or  currencies,  currency  unit or  units  or
          composite  currency  or  currencies  in which the  Securities  of such
          series are payable (except as otherwise  specified pursuant to Section
          301  for  the  Securities  of such  series)  sufficient  to pay on the
          Redemption Date the Redemption Price of, and (except if the Redemption
          Date shall be an Interest  Payment Date) accrued  interest on, all the
          Securities or portions thereof which are to be redeemed on that date.

               SECTION 1106.  Securities  Payable on Redemption Date.  Notice of
          redemption  having been given as  aforesaid,  the  Securities so to be
          redeemed shall, on the Redemption Date,  become due and payable at the
          Redemption  Price  therein  specified in the  currency or  currencies,
          currency  unit or units or composite  currency or  currencies in which
          the  Securities  of such  series  are  payable  (except  is  otherwise
          specified  pursuant to Section 301 for the  Securities of such series)
          (together with accrued interest,  if any, to the Redemption Date), and
          from and after such date  (unless  the  Company  shall  default in the
          payment of the Redemption Price and accrued  interest) such Securities
          shall, if the same were  interest-bearing,  cease to heir interest and
          the coupons for such interest appertaining to any Bearer Securities so
          to be redeemed,  except to the extent provided  below,  shall be void.
          Upon surrender of any such Security for redemption in accordance  with
          said notice,  together with all coupons, if any,  appertaining thereto
          maturing after the Redemption Date, such Security shall be paid by the
          Company at the Redemption Price,  together with accrued  interest,  if
          any, to the Redemption Date; provided,  however,  that installments of
          interest on Bearer  Securities whose Stated Maturity is on or prior to
          the  Redemption  Date  shall be  payable  only at an  office or agency
          located  outside the United  States  (except as otherwise  provided in
          Section  1002) and,  unless  otherwise  specified as  contemplated  by
          Section 301, only upon  presentation and surrender of coupons for such
          interest; and provided further that, except as otherwise provided with
          respect to  Securities  convertible  into Common  Shares or  Preferred
          Shares, installments of interest on Registered Securities whose Stated
          Maturity is on or prior to the Redemption Date shall be payable to the
          Holders of such  Securities,  or one or more  Predecessor  Securities,
          registered  as such at the close of  business on the  relevant  Record
          Dates according to their terms and the provisions of Section 307.

     If any Bearer Security  surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after  deducting from the  Redemption  Price an amount equal to the face
amount of all such missing  coupons,  or the surrender of such missing coupon or
coupons may be waived by the Company  and the Trustee if there be  furnished  to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption  Price,  such Holder shall be
entitled to receive the amount so deducted;  provided,  however,  that  interest
represented  by  coupons  shall be payable  only at an office or agency  located
outside the United  States  (except as otherwise  provided in Section 1002) and,
unless   otherwise   specified  as   contemplated  by  Section  301,  only  upon
presentation and surrender of those coupons.

     If any Security  called for redemption  shall not be so paid upon surrender
thereof for redemption,  the principal (and premium,  if any) shall, until paid,
bear interest from the Redemption Date at the rate borne by the Security.

               SECTION  1107.   Securities  Redeemed  in  Part.  Any  Registered
          Security  which  is to be  redeemed  only  in  part  (pursuant  to the
          provisions of this Article or of Article  Twelve) shall be surrendered
          at a Place of Payment therefor (with, if the Company or the Trustee so
          requires,  due endorsement by, or a written  instrument of transfer in
          form satisfactory to the Company and the Trustee duly executed by, the
          Holder  thereof or his attorney  duly  authorized  in writing) and the
          Company shall execute and the Trustee shall  authenticate  and deliver
          to the Holder of such Security  without  service charge a new Security
          or Securities of the same series,  of any authorized  denomination  as
          requested by such Holder in aggregate principal amount equal to and in
          exchange for the  unredeemed  portion of the principal of the Security
          so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

               SECTION 1201.  Applicability  of Article.  The provisions of this
          Article shall be applicable to any sinking fund for the  retirement of
          Securities of a series except as otherwise  specified as  contemplated
          by Section 301 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities  of any series is herein  referred to as a  "mandatory  sinking  fund
payment",  and any payment in excess of such minimum amount  provided for by the
terms of such  Securities  of any series is herein  referred to as an  "optional
sinking fund  payment".  It provided for by the terms of any  Securities  of any
series,  the cash amount of any mandatory sinking fund payment may be subject to
reduction  as provided in Section  1202.  Each  sinking  fund  payment  shall be
applied to the  redemption  of  Securities  of any series as provided for by the
terms of Securities of such series.

               SECTION  1202.   Satisfaction   of  Sinking  Fund  Payments  with
          Securities. The Company may, in satisfaction of all or any part of any
          mandatory  sinking fund payment  with respect to the  Securities  of a
          series, (1) deliver Outstanding  Securities of such series (other than
          any  previously  called for  redemption)  together  in the case of any
          Bearer   Securities  of  such  series  with  all   unmatured   coupons
          appertaining  thereto  and (2)  apply as a credit  Securities  of such
          series which have been redeemed  either at the election of the Company
          pursuant to the terms of such Securities or through the application of
          permitted optional sinking fund payments pursuant to the terms of such
          Securities,  as provided for by the terms of such Securities, or which
          have  otherwise  been  acquired  by the  Company;  provided  that such
          Securities  so  delivered  or  applied  as  a  credit  have  not  been
          previously so credited. Such Securities shall be received and credited
          for such  purpose by the Trustee at the  applicable  Redemption  Price
          specified in such Securities for redemption  through  operation of the
          sinking  fund and the amount of such  mandatory  sinking  fund payment
          shall be reduced accordingly.

               SECTION 1203. Redemption of Securities for Sinking Fund. Not less
          than 60 days prior to each sinking fund payment date for Securities of
          any series,  the  Company  will  deliver to the  Trustee in  Officers'
          Certificate  specifying  the  amount  of the  next  ensuing  mandatory
          sinking  fund  payment for that  series  pursuant to the terms of that
          series,  the portion  thereof,  if any,  which is to be  satisfied  by
          payment of cash in the currency or currencies,  currency unit or units
          or composite  currency or currencies  in which the  Securities of such
          series are payable (except as otherwise  specified pursuant to Section
          301 for the  Securities  of such series) and the portion  thereof,  if
          any, which is to be satisfied by delivering  and crediting  Securities
          of that series pursuant to Section 1202, and the optional  amount,  if
          any, to be added in cash to the next  ensuing  mandatory  sinking fund
          payment,  and will also deliver to the Trustee any Securities to be so
          delivered and credited. If such Officers' Certificate shall specify an
          optional  amount  to be added in cash to the  next  ensuing  mandatory
          sinking fund payment,  the Company shall thereupon be obligated to pay
          the amount therein  specified.  Not less than 30 days before each such
          sinking fund payment date the Trustee  shall select the  Securities to
          be  redeemed  upon  such  sinking  fund  payment  date  in the  manner
          specified in Section 1103 and cause notice of the  redemption  thereof
          to be given in the name of and at the  expense  of the  Company in the
          manner  provided in Section 1104.  Such notice having been duly given,
          the redemption of such Securities  shall be made upon the terms and in
          the manner stated in Sections 1106 and 1107.

                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

               SECTION 1301.  Applicability of Article.  Repayment of Securities
          of any series  before their  Stated  Maturity at the option of Holders
          thereof shall be made in accordance with the terms of such Securities,
          if any, and (except as otherwise specified by the terms of such series
          established pursuant to Section 301) in accordance with this Article.

               SECTION 1302.  Repayment of Securities.  Securities of any series
          subject to  repayment in whole or in part it the option of the Holders
          thereof  will,  unless  otherwise   provided  in  the  terms  of  such
          Securities,  be  repaid  at a  price  equal  to the  principal  amount
          thereof,  together  with  interest,  if any,  thereon  accrued  to the
          Repayment  Date  specified  in  or  pursuant  to  the  terms  of  such
          Securities. The Company covenants that at least one Business Day prior
          to the  Repayment  Date it will  deposit  with the  Trustee  or with a
          Paying  Agent (or, if the  Company is acting as its own Paying  Agent,
          segregate  and hold in trust as provided in Section 1003) an amount of
          money  in the  currency  or  currencies,  currency  unit or  units  or
          composite  currency  or  currencies  in which the  Securities  of such
          series are payable (except as otherwise  specified pursuant to Section
          301 for the Securities of such series) sufficient to pay the principal
          (or, if so provided by the terms of the  Securities  of any series,  a
          percentage of the  principal)  of, and (except if the  Repayment  Date
          shall be in  Interest  Payment  Date)  accrued  interest  on,  all the
          Securities  or portions  thereof,  as the case may be, to be repaid on
          such date.

               SECTION  1303.  Exercise  of  Option.  Securities  of any  series
          subject to repayment at the option of the Holders thereof will contain
          an "Option to Elect Repayment" form on the reverse of such Securities.
          In order for any  Security  to be repaid at the option of the  Holder,
          the Trustee must receive at the Place of Payment therefor specified in
          the terms of such  Security (or at such other place or places of which
          the  Company  shall  from  time to time  notify  the  Holders  of such
          Securities)  not earlier  than 60 days nor later than 30 days prior to
          the Repayment  Date (1) the Security so providing  for such  repayment
          together  with the  "Option to Elect  Repayment"  form on the  reverse
          thereof duly completed by the Holder (or by the Holder's attorney duly
          authorized   in  writing)  or  (2)  a   telegram,   telex,   facsimile
          transmission  or a  Letter  from a  member  of a  national  securities
          exchange,  or the National  Association  of Securities  Dealers,  Inc.
          ("NASD"),  or a commercial  bank or trust company in the United States
          setting  forth the name of the Holder of the  Security,  the principal
          amount of the  Security,  the  principal  amount of the Security to be
          repaid,  the CUSIP number,  if any, or a description  of the tenor and
          terms of the Security,  a statement that the option to elect repayment
          is being  exercised  thereby and a guarantee  that the  Security to be
          repaid,  together with the duly  completed  form  entitled  "Option to
          Elect  Repayment" on the reverse of the Security,  will be received by
          the  Trustee not later than the fifth  Business  Day after the date of
          such telegram,  telex,  facsimile  transmission  or letter;  provided,
          however, that such telegram,  telex,  facsimile transmission or letter
          shall only be effective if such  Security and form duly  completed are
          received by the Trustee by such fifth  Business  Day. If less than the
          entire principal amount of such Security is to be repaid in accordance
          with the terms of such Security, the principal amount of such Security
          to be repaid, in increments of the minimum denomination for Securities
          of such series,  and the denomination or denominations of the Security
          or  Securities  to be  issued to the  Holder  for the  portion  of the
          principal  amount  of  such  Security  surrendered  that  is not to be
          repaid,  must be  specified.  The  principal  amount  of any  Security
          providing for  repayment,  at the option of the Holder thereof may not
          be repaid in part if,  following such repayment,  the unpaid principal
          amount  of such  Security  would be less than the  minimum  authorized
          denomination  of Securities of the series of which such Security to be
          repaid is a part.  Except as otherwise  maybe provided by the terms of
          any  Security  providing  for  repayment  at the  option of the Holder
          thereof,  exercise  of the  repayment  option by the  Holder  shall be
          irrevocable unless waived by the Company.

               SECTION 1304. When Securities  Presented for Repayment Become Due
          and Payable.  If Securities  of any series  providing for repayment at
          the  option of the  Holders  thereof  shall have been  surrendered  as
          provided  in this  Article and as provided by or pursuant to the terms
          of such Securities,  such Securities or the portions  thereof,  as the
          case may be, to be repaid  shall  become due and  payable and shall be
          paid by the Company on the Repayment  Date therein  specified,  and on
          and after such Repayment Date (unless the Company shall default in the
          payment of such  Securities on such  Repayment  Date) such  Securities
          shall, if the same were  interest-bearing,  cease to bear interest and
          the coupons for such interest appertaining to any Bearer Securities so
          to be repaid, except to the extent provided below, shall be void. Upon
          surrender of any such Security for  repayment in accordance  with such
          provisions,  together with all coupons, if any,  appertaining  thereto
          maturing  after  the  Repayment  Date,  the  principal  amount of such
          Security so to be repaid shall be paid by the Company,  together  with
          accrued interest,  if any, to the Repayment Date;  provided,  however,
          that  coupons  whose Stated  Maturity is on or prior to the  Repayment
          Date shall be payable only at an office or agency located  outside the
          United  States  (except as  otherwise  provided in Section  1002) and,
          unless  otherwise   specified  pursuant  to  Section  301,  only  upon
          presentation and surrender of such coupons; and provided further that,
          in the case of Registered  Securities,  installments  of interest,  if
          any, whose Stated  Maturity is on or prior to the Repayment Date shall
          be payable (but without  interest  thereon,  unless the Company  shall
          default in the payment thereof) to the Holders of such Securities,  or
          one or more Predecessor Securities, registered as such at the close of
          business on the relevant Record Dates according to their terms and the
          provisions of Section 307.

     If any Bearer  Security  surrendered for repayment shall not be accompanied
by all appurtenant  coupons maturing after the Repayment Date, such Security may
be paid after deducting from the amount payable  therefor as provided in Section
1302 an amount  equal to the face  amount of all such  missing  coupons,  or the
surrender of such missing coupon or coupons may be waived by the Company and the
Trustee if there be  furnished  to them such  security or  indemnity as they may
require to save each of them and any Paying Agent  harmless.  If thereafter  the
Holder of such Security  shall  surrender to the Trustee or any Paying Agent any
such  missing  coupon in  respect of which a  deduction  shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted;  provided,  however,  that interest  represented  by coupons
shall be payable only at an office or agency  located  outside the United States
(except as otherwise  provided in Section 1002) and, unless otherwise  specified
as  contemplated by Section 301, only upon  presentation  and surrender of those
coupons.

     If the principal amount of any Security surrendered for repayment shall not
be so repaid upon  surrender  thereof,  such  principal  amount  (together  with
interest,  if any,  thereon accrued to such Repayment  Date) shall,  until paid,
bear  interest  from  the  Repayment  Date at the rate of  interest  or Yield to
Maturity (in the case of Original Issue Discount  Securities)  set forth in such
Security.

               SECTION 1305.  Securities  Repaid in Part.  Upon surrender of any
          Registered  Security  which is to be repaid in part only,  the Company
          shall  execute and the Trustee shall  authenticate  and deliver to the
          Holder of such Security,  without service charge and at the expense of
          the  Company,  a new  Registered  Security or  Securities  of the same
          series, of any authorized  denomination specified by the Holder, in an
          aggregate principal amount equal to and in exchange for the portion of
          the  principal  of such  Security  so  surrendered  which is not to be
          repaid.

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

               SECTION  1401.  Applicability  of  Article;  Company's  Option to
          Effect Defeasance or Covenant Defeasance. If, pursuant to Section 301,
          provision  is  made  for  either  or  both  of (a)  defeasance  of the
          Securities  of or within a series  under  Section 1402 or (b) covenant
          defeasance of the Securities of or within a series under Section 1403,
          then the  provisions of such Section or Sections,  as the case may be,
          together  with  the  other  provisions  of  this  Article  (with  such
          modifications thereto as may be specified pursuant to Section 301 with
          respect to any Securities), shall be applicable to such Securities and
          any coupons appertaining thereto, and the Company may at its option by
          Board Resolution, at any time, with respect to such Securities and any
          coupons  appertaining   thereto,   elect  to  have  Section  1402  (if
          applicable)  or  Section  1403  (if  applicable)  be  applied  to such
          Outstanding  Securities  and any  coupons  appertaining  thereto  upon
          compliance with the conditions set forth below in this Article.

               SECTION  1402.  Defeasance  and  Discharge.  Upon  the  Company's
          exercise of the above option  applicable  to this Section with respect
          to any  Securities of or within a series,  the Company shall be deemed
          to have been  discharged  from its  obligations  with  respect to such
          Outstanding  Securities  and any coupons  appertaining  thereto on the
          date  the   conditions   set  forth  in  Section  1404  are  satisfied
          (hereinafter,  "defeasance").  For this purpose, such defeasance means
          that the  Company  shall be  deemed to have  paid and  discharged  the
          entire indebtedness represented by such Outstanding Securities and any
          coupons appertaining  thereto,  which shall thereafter be deemed to be
          "Outstanding"  only for the  purposes  of  Section  1405 and the other
          Sections of this  Indenture  referred to in clauses (A) and (B) below,
          and to  have  satisfied  all  of  its  other  obligations  under  such
          Securities  and any coupons  appertaining  thereto and this  Indenture
          insofar as such  Securities and any coupons  appertaining  thereto are
          concerned  (and the  Trustee,  at the  expense of the  Company,  shall
          execute proper  instruments  acknowledging  the same),  except for the
          following which shall survive until otherwise terminated or discharged
          hereunder:  (A) the rights of Holders of such  Outstanding  Securities
          and any coupons appertaining thereto to receive, solely from the trust
          fund  described  in  Section  1404 and as more fully set forth in such
          Section, payments in respect of the principal of (and premium, if any)
          and interest,  if any, on such Securities and any coupons appertaining
          thereto when such payments are due, (B) the Company's obligations with
          respect to such Securities  under Sections 305, 306, 1002 and 1003 and
          with  respect to the payment of  Additional  Amounts,  if any, on such
          Securities as  contemplated  by Section 1008, (C) the rights,  powers,
          trusts,  duties and  immunities of the Trustee  hereunder and (D) this
          Article. Subject to compliance with this Article Fourteen, the Company
          may exercise its option under this Section  notwithstanding  the prior
          exercise  of its  option  under  Section  1403  with  respect  to such
          Securities and any coupons appertaining thereto.

               SECTION 1403. Covenant Defeasance. Upon the Company's exercise of
          the above  option  applicable  to this  Section  with  respect  to any
          Securities  of or within a series,  the Company shall be released from
          its  obligations  under  Sections  1004 to 1009,  inclusive,  and,  if
          specified  pursuant to Section  301, its  obligations  under any other
          covenant,  with respect to such Outstanding Securities and any coupons
          appertaining thereto on and after the date the conditions set forth in
          Section 1404 are satisfied (hereinafter,  "covenant defeasance"),  and
          such Securities and any coupons  appertaining thereto shall thereafter
          be deemed to be not  "Outstanding"  for the purposes of any direction,
          waiver, consent or declaration or Act of Holders (and the consequences
          of any thereof) in connection  with Sections 1004 to 1009,  inclusive,
          or such other covenant,  but shall continue to be deemed "Outstanding"
          for all other  purposes  hereunder.  For this  purpose,  such covenant
          defeasance means that, with respect to such Outstanding Securities and
          any coupons appertaining  thereto, the Company may omit to comply with
          and shall  have no  liability  in respect  of any term,  condition  or
          limitations  set forth in any such  Section  or such  other  covenant,
          whether directly or indirectly,  by reason of any reference  elsewhere
          herein to any such  Section  or such  other  covenant  or by reason of
          reference  in any such  Section  or such other  covenant  to any other
          provision  herein or in any other document and such omission to comply
          shall not  constitute a default or an Event of Default  under  Section
          501(4) or  501(8) or  otherwise,  as the case may be,  but,  except as
          specified  above,  the remainder of this Indenture and such Securities
          and any coupons appertaining thereto shall be unaffected thereby.

               SECTION 1404.  Conditions  to Defeasance or Covenant  Defeasance.
          The following  shall be the  conditions to application of Section 1402
          or Section 1403 to any  Outstanding  Securities  of or within a series
          and any coupons appertaining thereto:

                    (1) The Company shall  irrevocably  have deposited or caused
               to be deposited with the Trustee (or another  trustee  satisfying
               the  requirements  o(pound) Section 608 who shall agree to comply
               with the provisions of this Article Fourteen applicable to it) as
               trust  funds in trust for the  purpose  of making  the  following
               payments,  specifically  pledged as security  for, and  dedicated
               solely to, the benefit of the Holders of such  Securities and any
               coupons  appertaining  thereto,  (A) an amount in such  currency,
               currencies  or  currency  unit in which such  Securities  and any
               coupons  appertaining  thereto are then  specified  as payable at
               Stated Maturity, or (B) Government Obligations applicable to such
               Securities and coupons  appertaining  thereto  (determined on the
               basis of the currency,  currencies or currency unit in which such
               Securities and coupons appertaining thereto are then specified as
               payable at Stated  Maturity) which through the scheduled  payment
               of principal and interest in respect  thereof in accordance  with
               their terms will  provide,  not later than one day before the due
               date of any payment of  principal  of (and  premium,  if any) and
               interest, if any, on such Securities and any coupons appertaining
               thereto, money in an amount, or (C) a combination thereof, in any
               case,  in an amount,  sufficient,  without  consideration  of any
               reinvestment of such principal and interest,  in the opinion of a
               nationally  recognized  firm of  independent  public  accountants
               expressed  in a written  certification  thereof  delivered to the
               Trustee, to pay and discharge,  and which shall be applied by the
               Trustee (or other qualifying  trustee) to pay and discharge,  (i)
               the principal of (and premium,  if any) and interest,  if any, on
               such Outstanding  Securities and any coupons appertaining thereto
               on the  Stated  Maturity  of such  principal  or  installment  of
               principal  or  interest  and  (ii)  any  mandatory  sinking  fund
               payments or analogous  payments  applicable  to such  Outstanding
               Securities  and any  coupons  appertaining  thereto on the day on
               which such  payments are due and payable in  accordance  with the
               terms of this  Indenture and of such  Securities  and any coupons
               appertaining thereto;

                    (2) Such defeasance or covenant  defeasance shall not result
               in a breach or violation of, or constitute a default under,  this
               Indenture or any other material  agreement or instrument to which
               the Company is a party or by which it is bound;

                    (3) No Event of Default or event  which with notice or lapse
               of time or both would  become an Event of Default with respect to
               such Securities and any coupons  appertaining  thereto shall have
               occurred  and be  continuing  on the  date  of such  deposit  or,
               insofar as Sections 501(6) and 501(7) are concerned,  at any time
               during the  period  ending on the 91st day after the date of such
               deposit (it being  understood  that this  condition  shall not be
               deemed satisfied until the expiration of such period);

                    (4) In the  case of an  election  under  Section  1402,  the
               Company shall have delivered to the Trustee an Opinion of Counsel
               stating that (i) the Company has received from, or there has been
               published  by, the  Internal  Revenue  Service a ruling,  or (ii)
               since the date of execution of this  Indenture,  there has been a
               change in the  applicable  Federal income tax law, in either case
               to the effect that,  and based thereon such opinion shall confirm
               that, the Holder of such  Outstanding  Securities and any coupons
               appertaining  thereto will not recognize income, gain or loss for
               Federal  income tax purposes as a result of such  defeasance  and
               will be subject to Federal income tax on the same amounts, in the
               same  manner and at the same times as would have been the case if
               such defeasance had not occurred;


                    (5) In the  case of an  election  under  Section  1403,  the
               Company shall have delivered to the Trustee an Opinion of Counsel
               to the effect that the Holders of such Outstanding Securities and
               any coupons  appertaining thereto will not recognize income, gain
               or loss for  Federal  income  tax  purposes  as a result  of such
               covenant  defeasance and will be subject to Federal income tax on
               the same  amounts,  in the same  manner  and at the same times as
               would  have  been the case if such  covenant  defeasance  had not
               occurred;

                    (6) The  Company  shall  have  delivered  to the  Trustee an
               Officers'  Certificate  and an Opinion of Counsel,  each  stating
               that all  conditions  precedent to the  defeasance  under Section
               1402 or the covenant  defeasance  under Section 1403 (as the case
               may be) have been  complied with and an Opinion of Counsel to the
               effect  that  either  (i) as a result  of a deposit  pursuant  to
               subsection  (a) above and the related  exercise of the  Company's
               option  under  Section 1402 or Section 1403 (as the case may be),
               registration is not required under the Investment  Company Act of
               1940, as amended, by the Company, with respect to the trust funds
               representing  such deposit or by the Trustee for such trust funds
               or (ii) all  necessary  registrations  under  said Act have  been
               effected; and

                    (7)  Notwithstanding  any other  provisions of this Section,
               such  defeasance  or  covenant  defeasance  shall be  effected in
               compliance with any additional or substitute terms, conditions or
               limitations  which may be  imposed on the  Company in  connection
               therewith pursuant to Section 301.

               SECTION 1405.  Deposited  Money and Government  Obligations to Be
          Held  in  Trust;  Other  Miscellaneous  Provisions.   Subject  to  the
          provisions  of the last  paragraph  of  Section  1003,  all  money and
          Government  Obligations (or other property as may be provided pursuant
          to Section 301)  (including the proceeds  thereof)  deposited with the
          Trustee (or other  qualifying  trustee,  collectively  for purposes of
          this Section 1405, the "Trustee")  pursuant to Section 1404 in respect
          of  any   Outstanding   Securities  of  any  series  and  any  coupons
          appertaining  thereto  shall  be  held in  trust  and  applied  by the
          Trustee,  in accordance with the provisions of such Securities and any
          coupons  appertaining  thereto  and this  Indenture,  to the  payment,
          either  directly or through any Paying  Agent  (including  the Company
          acting as its own Paying Agent) as the Trustee may  determine,  to the
          Holders of such Securities and any coupons appertaining thereto of all
          sums due and to become  due  thereon  in  respect  of  principal  (and
          premium, if any) and interest and Additional Amounts, if any, but such
          money need not be  segregated  from other  funds  except to the extent
          required by law.

     Unless otherwise specified with respect to any Security pursuant to Section
301, if, after a deposit  referred to in Section  1404(a) has been made, (a) the
Holder of a Security in respect of which such  deposit was made is entitled  to,
and does, elect pursuant to Section 301 or the terms of such Security to receive
payment  in a currency  or  currency  unit other than that in which the  deposit
pursuant to Section 1404(a) has been made in respect, of such Security, or (b) a
Conversion Event occurs in respect of the currency or currency unit in which the
deposit pursuant to Section 1404(a) his been made, the indebtedness  represented
by such  Security and any coupons  appertaining  thereto shall be deemed to have
been,  and will be, fully  discharged  and satisfied  through the payment of the
principal of (and premium,  if any),  and interest,  if any, on such Security as
the same becomes due out of the  proceeds  yielded by  converting  (from time to
time as specified  below in the case of any such  election)  the amount or other

date, except,  with respect to a Conversion Event, for such currency or currency
unit in effect (as nearly as feasible) at the time of the Conversion Event.

     The Company  shall pay and  indemnify  the Trustee  against any tax, fee or
other charge imposed on or assessed against the Government Obligations deposited

thereof  other than any such tax,  fee or other  charge  which by law is for the
account  of  the  Holders  of  such  Outstanding   Securities  and  any  coupons
appertaining thereto.

Section 607, the Trustee  shall  deliver or pay to the Company from time to time
upon Company Request any money or Government  Obligations (or other property and
any proceeds  therefrom)  held by it as provided in Section  1404 which,  in the
opinion  of a  nationally  recognized  firm of  independent  public  accountants
expressed in a written  certification  thereof delivered to the Trustee,  are in
excess of the amount  thereof  which would then be required to be  deposited  to
effect a defeasance or covenant  defeasance,  as applicable,  in accordance with
this Article.

                                            ARTICLE FIFTEEN

                                    MEETINGS OF HOLDERS OF SECURITIES

               Resolution, or the Holders of at least 10% in principal amount of

               giving  notice  thereof as  provided  in  subsection  (1) of this
               Section.

               SECTION  1503.  Persons  Entitled  to  Vote  at  Meetings.  To be
          entitled  to vote at any  meeting  of  Holders  of  Securities  of any
          series,  a Person  shall be (1) a  Holder  of one or more  Outstanding
          Securities of such series,  or (2) a Person appointed by an instrument
          in writing as proxy for a Holder or Holders of one or more Outstanding
          Securities of such series by such Holder or Holders.  The only Persons
          who shall be  entitled  to be  present  or to speak at any  meeting of
          Holders of Securities  of any series shall be the Persons  entitled to
          vote at such meeting and their  counsel,  any  representatives  of the
          Trustee and its counsel and any representatives of the Company and its
          counsel.

               SECTION  1504.  Quorum;  Action.  The Persons  entitled to vote a
          majority in principal amount of the Outstanding Securities of a series
          shall  constitute a quorum for a meeting of Holders of  Securities  of
          such series;  provided,  however, that if any action is to be taken at
          such meeting with respect to a consent or waiver which this  Indenture
          expressly  provides  may be given by the  Holders  of not less  than a
          specified percentage in principal amount of the Outstanding Securities
          of a series, the Persons entitled to vote such specified percentage in
          principal  amount of the  Outstanding  Securities of such series shall
          constitute  a quorum.  In the  absence  of a quorum  within 30 minutes
          after the time appointed for any such meeting,  the meeting shall,  if
          convened at the request of Holders of  Securities  of such series,  be
          dissolved. In any other case the meeting may be adjourned for a period
          of not less than 10 days as  determined by the chairman of the meeting
          prior to the  adjournment of such meeting.  In the absence of a quorum
          at the  reconvening  of any such  adjourned  meeting,  such  adjourned
          meeting  may be  further  adjourned  for a period  of not less than 10
          days; at the reconvening of any meeting adjourned or further adjourned
          for  lack  of a  quorum,  the  persons  entitled  to  vote  25% in the
          aggregate  principal  amount of the Securities at the time outstanding
          shall  constitute  a quorum  for the taking of any action set forth in
          the notice of the original  meeting.  Notice of the reconvening of any
          adjourned  meeting  shall be given as  provided  in  Section  1502(a),
          except  that such  notice  need be given  only once not less than five
          days  prior  to the date on  which  the  meeting  is  scheduled  to be
          reconvened.

     Except as limited by the proviso to Section 902, any  resolution  presented
to a meeting or adjourned  meeting duly  reconvened at which a quorum is present
as aforesaid may be adopted by the affirmative  vote of the persons  entitled to
vote a majority in  aggregate  principal  amount of the  Outstanding  Securities
represented at such meeting;  provided,  however, that, except as limited by the
provisons to Section 902, any  resolution  with respect to any request,  demand,
authorization,  direction,  notice,  consent,  waiver or other action which this
Indenture  expressly  provides  may be made,  given or taken by the Holders of a
specified percentage,  which is less than a majority, in principal amount of the
Outstanding  Securities  of a series may be adopted at a meeting or an adjourned
meeting  duly  reconvened  and at which a quorum is present as  aforesaid by the
affirmative vote of the Holders of such specified percentage in principal amount
of the Outstanding Securities of that series.

     Any  resolution  passed or  decision  taken at any  meeting  of  Holders of
Securities  of any series duly held in  accordance  with this  Section  shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

     Notwithstanding  the  foregoing  provisions  of this Section  1504,  if any
action is to be taken at a meeting of Holders of  Securities  of any series with
respect to any  request,  demand,  authorization,  direction,  notice,  consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified  percentage  in  principal  amount of all
Outstanding  Securities  affected thereby,  or of the Holders of such series and
one or more additional series:

                    (i) there shall be no minimum  quorum  requirement  for such
               meeting; and

                    (ii) the principal  amount of the Outstanding  Securities of
               such  series  that  vote  in  favor  of  such  request,   demand,
               authorization, direction, notice, consent, waiver or other action
               shall be taken into account in determining  whether such request,
               demand,  authorization,  direction,  notice,  consent,  waiver or
               other action has been made, given or taken under this Indenture.

               SECTION  1505.   Determination  of  Voting  Rights;  Conduct  and
          Adjournment of Meetings.  (1)  Notwithstanding  any provisions of this
          Indenture,  the Trustee may make such reasonable regulations as it may
          deem advisable for any meeting of Holders of Securities of a series in
          regard to proof of the holding of Securities of such series and of the
          appointment of proxies and in regard to the  appointment and duties of
          inspectors  of votes,  the  submission  and  examination  of  proxies,
          certificates  and other  evidence of the right to vote, and such other
          matters  concerning  the  conduct  of the  meeting  as it  shall  deem
          appropriate.  Except as  otherwise  permitted  or required by any such
          regulations,  the holding of Securities  shall be proved in the manner
          specified  in Section  104 and the  appointment  of any proxy shall be
          proved  in the  manner  specified  in  Section  104 or by  having  the
          signature of the Person executing the proxy witnessed or guaranteed by
          any trust company, bank or banker authorized by Section 104 to certify
          to the holding of Bearer Securities. Such regulations may provide that
          written instruments appointing proxies,  regular on their face, may be
          presumed valid and genuine  without the proof specified in Section 104
          or other proof.

                    (2) The Trustee shall, by an instrument in writing appoint a
               temporary chairman of the meeting,  unless the meeting shall have
               been  called  by the  Company  or by  Holders  of  Securities  as
               provided  in Section  1502(2),  in which case the  Company or the
               Holders of Securities of the series  calling the meeting,  as the
               case may be, shall in like manner appoint a temporary chairman. A
               permanent chairman and a permanent secretary of the meeting shall
               be elected by vote of the Persons  entitled to vote a majority in
               principal  amount of the  Outstanding  Securities  of such series
               represented at the meeting.

                    (3) At any meeting  each Holder of a Security of such series
               or proxy shall be entitled to one vote for each $1,000  principal
               amount  of the  Outstanding  Securities  of such  series  held or
               represented by him; provided, however, that no vote shall be cast
               or counted at any meeting in respect of any  Security  challenged
               as not Outstanding and ruled by the chairman of the meeting to be
               not Outstanding.  The chairman of the meeting shall have no right
               to vote,  except  as a Holder  of a  Security  of such  series or
               proxy.

                    (4) Any meeting of Holders of  Securities of any series duly
               called  pursuant to Section 1502 at which a quorum is present may
               be  adjourned  from time to time by  Persons  entitled  to vote a
               majority in principal  amount of the  Outstanding  Securities  of
               such series  represented  at the meeting,  and the meeting may be
               held as so adjourned without further notice.

               SECTION 1506.  Counting  Votes and Recording  Action of Meetings.
          The vote upon any  resolution  submitted  to any meeting of Holders of
          Securities of any series shall be by written ballots on which shall be
          subscribed  the signatures of the Holders of Securities of such series
          or of their  representatives  by proxy and the  principal  amounts and
          serial  numbers of the  Outstanding  Securities of such series held or
          represented  by them.  The  permanent  chairman of the  meeting  shall
          appoint two  inspectors of votes who shall count all votes cast at the
          meeting for or against any resolution and who shall make and file with
          the  secretary  of the  meeting  their  verified  written  reports  in
          duplicate  of all votes  cast at the  meeting.  A record,  at least in
          duplicate, of the proceedings of each meeting of Holders of Securities
          of any Series  shall be prepared by the  secretary  of the meeting and
          there shall be attached  to said  record the  original  reports of the
          inspectors of votes on any vote by ballot taken thereat and affidavits
          by one or more persons having  knowledge of the fact,  setting forth a
          copy of the notice of the  meeting  and  showing  that said notice was
          given as provided in Section 1502 and, if  applicable,  Section  1504.
          Each copy  shall be  signed  and  verified  by the  affidavits  of the
          permanent  chairman  and  secretary  of the  meeting and one such copy
          shall be  delivered  to the  Company  and another to the Trustee to be
          preserved  by the  Trustee,  the latter to have  attached  thereto the
          ballots voted at the meeting.  Any record so signed and verified shall
          be conclusive evidence of the matters therein stated.

                                 ARTICLE SIXTEEN

                                  SUBORDINATION

               SECTION 1601.  Agreement to Subordinate.  The Company agrees, and
          each Holder by  accepting  a Security  agrees,  that the  indebtedness
          evidenced by the Securities is  subordinated  in right of payment,  to
          the extent and in the manner  provided in this  Article,  to the prior
          payment in full of all Senior Debt and that the  subordination  is for
          the benefit of the holders of Senior Debt.

               SECTION  1602.  Liquidation;  Dissolution;  Bankruptcy.  Upon any
          distribution   to  creditors  of  the  Company  in  a  liquidation  or
          dissolution  of  the  Company  or  in  a  bankruptcy,  reorganization,
          insolvency, receivership or similar proceeding relating to the Company
          or its property:

                    (l)  holders  of Senior  Debt shall be  entitled  to receive
               payment  in  full  in  cash  of the  principal  of  and  interest
               (including  interest  accruing after the commencement of any such
               proceeding)  to the date of  payment on the  Senior  Debt  before
               Holders  shall be entitled to receive any payment of principal of
               or interest on Securities;

                    (2)  until  the  Senior  Debt is paid in full in  cash,  any
               distribution  to which  Holders  would be  entitled  but for this
               Article  shall  be made  to  holders  of  Senior  Debt  as  their
               interests may appear,  except that Holders may receive securities
               that are  subordinated to Senior Debt to at least the same extent
               as the Securities; and

                    (3) the  Trustee is entitled to rely upon an order or decree
               of a  court  of  competent  jurisdiction  or a  certificate  of a
               bankruptcy  trustee or other similar  official for the purpose of
               ascertaining   the  persons   entitled  to  participate  in  such
               distribution,  the holders of Senior Debt and other Company debt,
               the amount  thereof or payable  thereon  and all other  pertinent
               facts  relating to the Trustee's  obligations  under this Article
               Sixteen.

               SECTION  1603.  Default on Senior  Debt.  The Company may not pay
          principal  or  interest  on the  Securities  and may not  acquire  any
          Securities  for cash or  property  other  than  capital  shares of the
          Company if:

                    (1) a default on Senior Debt occurs and is  continuing  that
               permits  holders of such Senior Debt to accelerate  its maturity;
               and

                    (2) the default is the subject of  judicial  proceedings  or
               the Company  receives a notice of the  default  from a person who
               may give it pursuant to Section 1611. If the Company receives any
               such  notice,  a  similar  notice  received  within  nine  months
               thereafter  relating  to the same  default  on the same  issue of
               Senior Debt shall not be effective  for purposes of this Section.
               The Company may resume payments on the Securities and may acquire
               them when:

                         (a) the default is cured or waived; or

                         (b) 120 days  pass  after  the  notice  is given if the
                    default is not the subject of judicial proceedings,

if this Article otherwise permits the payment or acquisition at that time.

               SECTION  1604.  Acceleration  of  Securities.  If  payment of the
          Securities is accelerated because of an Event of Default,  the Company
          shall promptly notify holders of Senior Debt of the acceleration.  The
          Company  may  pay  the  Securities   when  120  days  pass  after  the
          acceleration occurs if this Article permits the payment at that time.

               SECTION  1605.  When   Distribution  Must  Be  Paid  Over.  If  a
          distribution  is made to Holders that  because of this Article  should
          not have been made to them,  the Holders who receive the  distribution
          shall hold it in trust for  holders of Senior  Debt and pay it over to
          them as their interests may appear.

               SECTION  1606.  Notice by  Company.  The Company  shall  promptly
          notify  the  Trustee  and any Paying  Agent of any facts  known to the
          Company  that would  cause a payment of  principal  of or  interest on
          Securities to violate this Article.

               SECTION 1607. Subrogation.  After all Senior Debt is paid in full
          and until the Securities are paid in full, Holders shall be subrogated
          to the  rights of  holders  of Senior  Debt to  receive  distributions
          applicable to Senior Debt to the extent that  distributions  otherwise
          payable to the  Holders  have been  applied  to the  payment of Senior
          Debt. A distribution made under this Article to holders of Senior Debt
          which otherwise would have been made to Holders is not, as between the
          Company and Holders, a payment by the Company on Senior Debt.

               SECTION 1608.  Relative Rights. This Article defines the relative
          rights  of  Holders  and  holders  of  Senior  Debt.  Nothing  in this
          Indenture shall:

                    (1)  impair,  as  between  the  Company  and  Holders,   the
               obligation of the Company,  which is absolute and  unconditional,
               to pay principal of and interest on the  Securities in accordance
               with their terms;

                    (2) affect the relative  rights of Holders and  creditors of
               the Company other than holders of Senior Debt; or

                    (3) prevent the  Trustee or any Holder from  exercising  its
               available  remedies  upon an Event  of  Default,  subject  to the
               rights  of  holders  of  Senior  Debt  to  receive  distributions
               otherwise payable to Holders.

     If the  Company  fails  because  of this  Article  to pay  principal  of or
interest on a Security on the due date, the failure is still a default.

               SECTION 1609.  Subordination  May Not Be Impaired by Company.  No
          right of any holder of Senior Debt to enforce the subordination of the
          indebtedness  evidenced by the Securities shall be impaired by any act
          or failure to act by the Company or by its failure to comply with this
          Indenture.

               SECTION 1610. Distribution or Notice to Representative.  Whenever
          a  distribution  is to be made or a notice  given to holders of Senior
          Debt,  the  distribution  may be made  and the  notice  given to their
          Representative.

               SECTION 1611.  Rights of Trustee and Paying Agent. The Trustee or
          any Paying Agent may continue to make payments on the Securities until
          it  receives  written  notice of facts that  would  cause a payment of
          principal of or interest on the  Securities  to violate this  Article.
          Only the Company,  a Representative  or a holder of an issue of Senior
          Debt that has no Representative may give the written notice.

               The Trustee has no  fiduciary  duty to the holders of Senior Debt
          other  than as  created  under  this  Indenture.  The  Trustee  in its
          individual  or any other  capacity  may hold Senior Debt with the same
          rights it would have if it were not Trustee.

               The Company's  obligation  to pay, and the Company's  payment of,
          the  Trustee's  fees  pursuant  to Section 606 are  excluded  from the
          operation of this Article Sixteen.

               This  Indenture  may be executed  in any number of  counterparts,
          each of which so executed  shall be deemed to be an original,  but all
          such  counterparts  shall  together  constitute  but one and the  same
          Indenture.

     IN WITNESS  WHEREOF,  the parties  hereto have caused this  Indenture to be
duly executed all as of the day and year first above written.

Re:  $100,000,000  Aggregate  Offering  Price of Securities of United  Investors
     Realty Trust

Gentlemen:

         We are acting as securities counsel to United Investors Realty Trust, a
Texas real estate  investment  trust (the  "Company"),  in  connection  with the
registration statement on Form S-3 (the "Registration Statement") being filed by
you with the Securities and Exchange  Commission  (the  "Commission")  under the
Securities  Act of 1933,  as amended (the "Act"),  relating to the offering from
time to time  pursuant  to Rule  415  under  the Act,  as set in the  prospectus
contained in the  Registration  Statement  (the  "Prospectus")  and as to be set
forth  in  one or  more  supplements  to  the  Prospectus  (each  a  "Prospectus
Supplement"),  by the Company of up to $100,000,000  aggregate offering price of
(i) common shares of beneficial  interest,  no par value (the "Common  Shares"),
(ii) one or more series of preferred shares of beneficial interest, no par value
(the  "Preferred  Shares"),  (iii) one or more series of senior or  subordinated
debt  securities  (the  "Debt  Securities"),  (iv)  warrants  to  purchase  Debt
Securities,  Preferred Shares or Common Shares (referred to herein  collectively
as the "Securities Warrants"), and/or (v) rights to purchase Preferred Shares or
Common Shares  (referred to herein  collectively  as the  "Rights").  The Common
Shares,  Preferred Shares,  Debt Securities,  Securities Warrants and Rights are
collectively referred to as the "Securities."

         In our capacity as your counsel in connection  with such  registration,
we have made such legal and factual  examinations  and  inquiries,  including an
examination  of originals or copies,  certified or otherwise  identified  to our
satisfaction,  of such  documents,  corporate  records,  certificates  of public
officials  and other  instruments  as we have deemed  necessary  or advisable in
connection  with this  opinion,  including  (a) the First  Amended and  Restated
Declaration of Trust of the Company and the First Amended and Restated Bylaws of
the Company, each as amended to date, and (b) the Registration Statement. In our
examination,  we have  assumed  the  genuineness  of all  signatures,  the legal
capacity of natural persons,  the authenticity of all documents  submitted to us
as originals, the conformity to original documents of all documents submitted to
us as certified or photostatic copies, the authenticity of the originals of such
copies and the authenticity of telegraphic or telephonic confirmations of public
officials and others.  As to facts material to our opinion,  we have relied upon
certificates or telegraphic or telephonic  confirmations of public officials and
certificates,  documents,  statements  and other  information  of the Company or
representatives or officers thereof.

         The  opinions  set  forth  below  address  the  effect  on the  subject
transaction  only of the federal laws of the United States and the internal laws
of  the  State  of  Texas,  and  we  express  no  opinion  with  respect  to the
applicability  thereto,  or the  effect  thereon,  of  the  laws  of  any  other
jurisdiction.

         Subject to the foregoing and the other matters set forth herein,  it is
our opinion that, as of the date hereof:

          1. The registration of the Common Shares has been duly authorized, and
     upon issuance,  delivery and payment therefor in the manner contemplated by
     the Registration Statement and the applicable Prospectus Supplement, and in
     accordance with the applicable definitive purchase, underwriting or similar
     agreement approved by the Board, the Common Shares will be duly authorized,
     validly issued, fully paid and nonassessable;

          2. The  registration of the Preferred  Shares has been duly authorized
     by the Company, and when the Preferred Shares have been duly established in
     accordance  with  the  terms  of the  Company's  Statement  of  Designation
     defining the rights and preferences of the Preferred Shares, and applicable
     law,  and,  upon  issuance,  delivery  and  payment  therefor in the manner
     contemplated by the  Registration  Statement and the applicable  Prospectus
     Supplement,  and in accordance  with the  applicable  definitive  purchase,
     underwriting  or similar  agreements  approved by the Board,  the Preferred
     Shares  will  be  duly   authorized,   validly   issued,   fully  paid  and
     nonassessable;

          3. The registration of the Debt Securities has been duly authorized by
     the Company, and when the Debt Securities have been duly established by the
     applicable  Indenture,  duly authenticated by the Trustee and duly executed
     and  delivered  on  behalf  of the  Company  against  payment  therefor  in
     accordance with the terms and provisions of the applicable Indenture and as
     contemplated by the  Registration  Statement and the applicable  Prospectus
     Supplement,  and in accordance  with the  applicable  definitive  purchase,
     underwriting or similar  agreement  approved by the Board of Trust Managers
     (the  "Board"),  the Debt  Securities  will  constitute  legally  valid and
     binding  obligations  of the  Company,  enforceable  against the Company in
     accordance with their terms;

          4.  The  registration  of  the  Securities   Warrants  has  been  duly
     authorized by the Company,  and when the final terms thereof have been duly
     established,  and when duly  executed  and  delivered  by the  Company  and
     countersigned  by the applicable  financial  institution  identified as the
     warrant  agent (the  "Warrant  Agent") in  accordance  with the  applicable
     warrant  agreement (the "Warrant  Agreement") and delivered to and paid for
     by the purchasers  thereof in the manner  contemplated by the  Registration
     Statement and the applicable Prospectus Supplement,  and in accordance with
     the  applicable  definitive  purchase,  underwriting  or similar  agreement
     approved by the Board,  the  Securities  Warrants will  constitute  legally
     valid and  binding  obligations  of the  Company,  enforceable  against the
     Company in accordance with their respective terms; and

          5. The  registration  of the  Rights has been duly  authorized  by the
     Company,  and when the final terms thereof have been duly established,  and
     when duly  executed and delivered by the Company and  countersigned  by the
     applicable  financial  institution as the rights agent (the "Rights Agent")
     in accordance with applicable rights agreement (the "Rights Agreement") and
     delivered  to and  paid  for  by  the  purchasers  thereof  in  the  manner
     contemplated  by the  Prospectus  Supplement,  and in  accordance  with the
     applicable definitive purchase,  underwriting or similar agreement approved
     by the  Board,  the  Rights  will  constitute  legally  valid  and  binding
     obligations of the Company,  enforceable  against the Company in accordance
     with their respective terms.

         The opinions set forth above are subject to the  following  exceptions,
limitations  and  qualifications:  (i) the  effect  of  bankruptcy,  insolvency,
reorganization,  moratorium  or other  similar  laws now or  hereafter in effect
relating to or affecting the rights and remedies of  creditors;  (ii) the effect
of  general  principles  of  equity,  whether  enforcement  is  considered  in a
proceeding in equity or at law, and the discretion of the court before which any
proceeding  therefor may be brought;  (iii) the  unenforceability  under certain
circumstances  under law or court  decisions  of  provisions  providing  for the
indemnification  of or contribution to a party with respect to a liability where
such  indemnification  or  contribution  is contrary to public  policy;  (iv) we
express  no opinion  concerning  the  enforceability  of the waiver of rights or
defenses  contained  in  Section  514 of the  Indenture;  and (v) we  express no
opinion with respect to whether  acceleration  of Debt Securities may affect the
collectibility of any portion of the stated principal amount thereof which might
be determined to constitute unearned interest thereon.

         To the extent that the  obligations  of the Company  under each Warrant
Agreement may be dependent upon such matters, we assume for the purposes of this
opinion that the Warrant Agent is duly organized,  validly  existing and in good
standing under the laws of its  jurisdiction of  organization;  that the Warrant
Agent is duly qualified to engage in the activities  contemplated by the Warrant
Agreement;  that the Warrant  Agreement has been duly  authorized,  executed and
delivered by the Warrant  Agent and  constitutes  the legally  valid and binding
obligation  of the  Warrant  Agent  enforceable  against  the  Warrant  Agent in
accordance  with its terms;  that the Warrant Agent is in compliance,  generally
with respect to acting as a Warrant Agent under the Warrant Agreement,  with all
applicable  laws and  regulations;  and that the Warrant Agent has the requisite
organizational  and legal power and authority to perform its  obligations  under
the Warrant Agreement.

         To the extent that the  obligations  of the  Company  under each Rights
Agreement  may be dependent  upon such  matters,  we assume for purposes of this
opinion that the Rights Agent is duly  organized,  validly  existing and in good
standing under the laws of its  jurisdiction  of  organization;  that the Rights
Agent is duly  qualified to engage in the activities  contemplated  by the Right
Agreement;  that the Rights  Agreement  has been duly  authorized,  executed and
delivered  by the Rights  Agent and  constitutes  the legally  valid and binding
obligation  of  the  Rights  Agent  enforceable  against  the  Rights  Agent  in
accordance  with its terms;  that the Rights Agent is in  compliance,  generally
with  respect to acting as a Rights Agent under the Rights  Agreement,  with all
applicable  laws and  regulations;  and that the Rights Agent has the  requisite
organizational  and legal power and authority to perform its  obligations  under
the Rights Agreement.

         For  the  purposes  of  this  opinion,  we have  assumed  that  (i) the
Registration  Statement,  and any amendments thereto  (including  post-effective
amendments),  will have become effective, (ii) a Prospectus Supplement will have
been prepared and filed with the Commission  describing  the Securities  offered
thereby,  (iii)  all  Securities  will be  issued  and sold in  compliance  with
applicable  federal and state  securities  laws and in the manner  stated in the
Registration  Statement and the appropriate  Prospectus  Supplement,  and (iv) a
definitive  purchase,  underwriting  or similar  agreement  with  respect to any
Securities  offered will have been duly  authorized  and  validity  executed and
delivered by the Company and the other parties thereto.

         We  consent  to  your  filing  this   opinion  as  an  exhibit  to  the

                                            _________, 1999


United Investors Realty Trust
5847 San Felipe, Suite 850
Houston, Texas 77057

Ladies and Gentlemen:

         We have  acted  as  counsel  to  United  Investors  Realty  Trust  (the
"Trust"),  a  Texas  real  estate  investment  trust,  in  connection  with  the
Registration  Statement  on Form S-3  dated  April 5,  1999  (the  "Registration
Statement") filed with the Securities and Exchange Commission in connection with
registration under the Securities Act of 1933, as amended. We have been asked to
provide an opinion on certain  federal income tax matters  related to the Trust.
Capitalized  terms used in this letter and not otherwise defined herein have the
meaning set forth in the Registration Statement an the accompanying prospectus.

         The opinions set forth in this letter are based on relevant  provisions
of the  Internal  Revenue  Code of  1986,  as  amended  (the  "Code"),  Treasury
Regulations   promulgated   thereunder   (including   proposed   and   temporary
Regulations),  and  interpretations  of the  foregoing  as  expressed  in  court
decisions,  the  legislative  history and  existing  administrative  rulings and
practices of the Internal  Revenue Service ("IRS")  (including its practices and
policies in issuing  private  letter  rulings,  which are not binding on the IRS
except with respect to a taxpayer that  receives  such a ruling),  all as of the
date hereof.  These provisions and interpretations are subject to change,  which
may or may not be retroactive in effect,  that might result in  modifications of
our opinion.

         In rendering the  following  opinion,  we have examined such  statutes,
regulations,  records,  certificates  and other  documents as we have considered
necessary or appropriate  as a basis for such opinion,  including the following:
(1) the Registration  Statement and the accompanying  prospectus;  (2) the First
Amended and  Restated  Declaration  of Trust and the First  Amended and Restated
Bylaws of the Trust as amended to date (collectively,  the "Charter"); and (3) a
written  tax  representation  letter of the Trust  executed by an officer of the
Trust, dated on or about the date hereof (the "Officer's Certificate")

         In our review,  we have  assumed,  with your  consent,  that all of the
representations  and  statements set forth in the documents we reviewed are true
and correct, and all of the obligations imposed under such documents, including,
without limitation, the Charter, have been and will be performed or satisfied in
accordance with their terms. In connection with rendering the opinion herein, we
have also assumed (without any independent investigation or review thereof) that
all  actions  described  in the  Registration  Statement  and  the  accompanying
prospectus will be consummated as described therein  (including  satisfaction of
all covenants and conditions to the obligations of the parties without amendment
or waiver  thereof) and  completed  in a timely  fashion and that the Trust will
comply with all reporting  obligations required under the Code, and the Treasury
Regulations thereunder.

         For purposes of rendering our opinion,  we have not made an independent
investigation  or audit of any of the facts set forth in any of the documents we
have  examined,   including  the   Registration   Statement  and  the  Officer's
Certificate or with regard to the assumptions set forth above. Consequently,  we
have relied upon your  representations  and have  assumed  that the  information
presented  in  such  documents  or  otherwise  furnished  to us  accurately  and
completely describes all material facts relevant to our opinions.

         Any inaccuracy in, or breach of, any of the aforementioned  statements,
representations,  warranties and assumptions or any change after the date hereof
in applicable  law could  adversely  affect our opinion.  No ruling has been (or
will be) sought from the IRS by the Trust as to the  federal  income tax matters
addressed in this opinion.

         Based upon our  examination  of the foregoing  items and subject to and
limited by the assumptions, exceptions, limitations and qualifications set forth
herein, we are of the opinion that the Trust has qualified as a REIT for federal
income tax purposes for the taxable year ended December 31, 1998 and the form of
organization  of the  Trust,  its  operations  through  the date  hereof and its
proposed operations for future periods,  are such as to enable it to continue to
satisfy the  requirements  for  qualification  as a REIT for federal  income tax
purposes in subsequent  taxable years  provided that in each such year the Trust
meets  the  applicable  asset   composition,   source  of  income,   shareholder
diversification,  distribution, recordkeeping and other requirements of the Code
necessary  for the  Trust  to  qualify  as a REIT;  and the  information  in the
Registration  Statement  and  the  accompanying  prospectus  under  the  caption
"Federal  Income Tax  Consequences"  fairly  summarizes  the federal  income tax
considerations  that are  likely to be  material  to the Trust and a holder of a
common share of the Trust and, to the extent that it constitutes  matters of law
or legal  conclusions,  is correct in all material  respects and presents fairly
the information  required to be disclosed therein. We will review the discussion
in the  "Federal  Income  Tax  Consequences"  section  contained  in one or more
supplements to the prospectus contained in the Registration Statement.

         We assume no  obligation  to advise you of any  changes in our  opinion
subsequent to the date hereof. The Trust's  qualification as a REIT depends upon
the  Trust's  ability  to meet on a  continuing  basis,  through  actual  annual
operating and other results, the various requirements under the Code with regard
to, among other things,  the sources of its gross income, the composition of its
assets, the level of its distributions to stockholders, and the diversity of its
stock  ownership.  We have  not  undertaken  to  review  or  audit  the  Trust's
compliance  with these  requirements  on a  continuing  basis.  Accordingly,  no
assurance can be given that the actual  operating  results of the Trust, and the
entities in which the Trust owns  interests,  the sources of their  income,  the
nature of their  assets,  the level of  distributions  to  shareholders  and the
diversity of stock  ownership  for any given  taxable year has satisfied or will
satisfy the  requirements  under the Code for  qualification  and  taxation as a
REIT.

         An opinion of counsel  merely  represents  counsel's best judgment with
respect to the  probable  outcome on the merits and is not binding on the IRS or
the courts.  There can be no assurance that  positions  contrary to our opinions
will not be taken by the IRS, or that a court  considering  the issues would not
hold contrary to such opinions.

         This  opinion is  furnished  to you solely for the purpose of complying
with applicable  securities laws. This opinion may not be used or relied upon by
any other  person or for any other  purpose and may not be  circulated,  quoted,
filed  with a  governmental  agency or  otherwise  referred  to for any  purpose
without our prior written  consent.  Notwithstanding  the foregoing,  consent to
being  named as counsel to the  Company in the  Registration  Statement,  to the
references  in the  Registration  Statement to our firm and to the  inclusion of
this opinion letter as an exhibit to the Registration  Statement. In giving such
consent,  we do not thereby admit that we are an "expert"  within the meaning of
the Securities Act of 1933 as amended.

                                Sincerely yours,



                                LOCKE LIDDELL & SAPP LLP
