RE: Valuation Analysis for High Equity Partners L.P. - Series 88 ("the
Partnership")

Gentlemen:

By letter dated June 14, 2000, the Partnership retained Insignia/ESG, Inc.
("Insignia") to undertake four separate valuation analyses with respect to the
Partnership on behalf of the Partnership. The engagement letter states that the
Partnership proposes to be converted (the "Transaction") into a real estate
investment trust (the "REIT") as described by the Partnership's management in
Amendment No.4 to the Registration Statement on Form S-4 of the REIT. We have
assumed that in the Transaction, each Partnership Unit would be exchanged for
three REIT shares. In each of the analyses, the value arrived at is expressed as
an amount per proposed REIT share. The following summarizes the specific
analyses that the Partnership asked us to perform.

1. An examination of the secondary market trading history ("Secondary Market
Trading History Analysis") of the existing units of limited partnership interest
in the Partnership (the "Partnership Units") on the limited secondary markets;

2. An analysis of the value of the net assets of the Partnership, and the amount
of cash available for distribution to partners, were the Partnership to
liquidate all of its real estate (the "Properties") and other assets
("Liquidation Analysis");

3. An analysis of the value of the Partnership Units, on a going concern basis,
based upon the future cash flow to be received by partners ("Going Concern
Analysis");

4. On the assumption that the Partnership was converted to the REIT, an analysis
of the expected range in which the REIT shares would trade based upon an
examination of comparable publicly traded real estate investment trusts
("Conversion and Comparable Company Analysis").

<PAGE>

In performing these analyses, we reviewed the documents provided to us by the
Partnership which are identified on Schedule A to this letter and we have relied
upon and assumed, without independent verification or investigation, the
accuracy and completeness of all financial and other information provided to or
discussed with us by the Partnership, its general partner and their respective
employees, representatives and affiliates. With respect to forecasts of the
future financial condition and operating results of the Partnership and the
proposed REIT provided to or discussed with us, we assumed, at the direction of
the management of the Partnership, without independent verification or
investigation, that such forecasts were reasonably prepared on bases reflecting
the best currently available information, estimates and good faith judgments of
the management of the Partnership. We have also relied upon assurances of the
management of the Partnership that they are unaware of any facts that would make
the historical information or forecasts incomplete or misleading. Except for the
appraisals provided to us by the Partnership referred to below, we have neither
made nor obtained any independent evaluations or appraisals of the assets or the
liabilities (contingent or otherwise) of the Partnership. The analyses do not
address the tax consequences of any aspect of the proposed Transaction (other
than transfer taxes assumed with the disposition of real estate upon
liquidation). We are not expressing any opinion as to the underlying evaluation,
future performance or long-term viability of the Partnership or the proposed
REIT, or the price at which Partnership Units or proposed REIT shares will
trade, whether or not the Transaction occurs. Our analyses are necessarily based
on the information available to us and general economic, financial and
securities market conditions and circumstances as they exist and can be
evaluated by us on the date hereof. It should be understood that, although
subsequent developments may affect our analyses, we do not have any obligation
to update, revise or reaffirm the analyses.

OVERVIEW OF CUSHMAN AND WAKEFIELD APPRAISAL METHODS

Insignia was provided with Cushman & Wakefield's ("Cushman") appraised values as
of June 30, 2000 for the Properties ("Appraised Values"). The valuation approach
selected by Cushman for the Properties varies based on each Property's
particular demise, encumbrances and the market conditions affecting it. With the
exception of the Properties identified as Tri-Columbus, Melrose Crossing II and
three Super Valu properties, Cushman employed a discounted cash flow approach
with, in most cases, support from the sales comparison approach.

Under the discounted cash flow approaches, the cash flows for the Properties for
the next 10 years were projected. At the end of the 10th year a terminal value
("Terminal Value") was added to the cash flow by capitalizing the projected 11th
year net operating income at a rate ("Appraised Cap Rate") selected by Cushman
and then deducting the anticipated costs associated with selling the Properties
("Selling Costs"). The cash flows were then discounted to present utilizing a
discount rate ("Appraised Discount Rate") selected by Cushman.

The values for Melrose Crossing II were determined based on the replacement cost
approach.

                                       2

<PAGE>

The values for Tri-Columbus and three Super Valu properties were based on a
direct capitalization of income approach through which Cushman capitalized
estimated stabilized net operating income at the Appraised Cap Rate selected by
Cushman.

For the properties held through joint venture interests, Cushman provided a
second set of values ("Discounted J.V. Values") which contemplate a 25% to 35%
discount ("Joint Venture Discounts") to the Appraised Values in consideration of
the illiquidity associated with the ownership structure. The Discounted J.V.
Values together with the Appraised Values for the non-joint venture Properties
together constitute the Adjusted Appraisals ("Adjusted Appraisals").

1. SECONDARY MARKET TRADING HISTORY ANALYSIS

The Secondary Market Trading History Analysis is intended to value the
Partnerships based on the recent trading prices of Partnership Units. These
secondary markets cannot be characterized as either efficient or liquid markets,
and Partnership Units are expected to trade at a discount to liquidation value
or value based upon a going-concern analysis of the Partnership. The information
provided to us by the Partnership included the high sale price and low sale
price per Partnership Unit during each two months of trading from April 1, 1996
to August 31, 2000, together with a weighted average price per Partnership Unit
for the same period. The ranges of values indicated by this analysis are based
upon that secondary market trading data, with particular consideration given to
the weighted average trading prices in August and September, 2000, the most
recent period for which data was provided. Also considered are the trends in
prices over the period for which data was provided. The resulting range of
values per REIT share from the Secondary Market Trading History Analysis is
indicated to be $29.41 to $33.16 per share.

 2. LIQUIDATION ANALYSIS

The Liquidation Analysis is intended to value the Partnership's net assets
assuming a complete liquidation of the Partnership on a current basis. For
purposes of this analysis, we assumed that the non-joint venture Properties
would sell at their Appraised Values and that the interests in joint ventures
would sell at the values indicated in the Adjusted Appraisals.

The Liquidation Analysis assumes an adjustment for the anticipated property
disposition costs consisting of estimated transfer taxes, brokerage commissions
and closing costs ("Disposition Costs"). To the extent Properties were appraised
based on a discounted cash flow methodology, Disposition Costs were assumed to
be equal to Selling Costs utilized by Cushman in determining Terminal Value. For
Properties valued based on either a direct capitalization method or replacement
cost method, Disposition Costs were assumed to be 5% of Adjusted Appraisals.

Consideration was also given for the non-real estate assets of the Partnership.
The net assets considered were the Assets and Liabilities reported on the
Balance Sheet at September 30, 2000 included in the Form 10-Q of the Partnership
for the period ended September 30, 2000 and were included at the value set forth
on the Balance Sheet with the exception of the assets classified as Other Assets
on the Balance Sheets. The only

                                       3

<PAGE>

Other Assets included were those that were deemed to have value upon
liquidation, i.e. furniture, fixtures & equipment and receivables.

The fee giveback obligation was also considered to be realized by the limited
partners of the Partnership at full value as of September 30, 2000.

Finally, consideration was given for the partnership dissolution costs that were
estimated at $500,000 for the Partnership.

No general partner liquidation fees or priority distributions were considered,
as the partnership liquidation values would not provide for same under the terms
of the Partnership Agreement.

The resulting range of values per proposed REIT share based on the Liquidation
Analysis is indicated to be $44.14 to $49.77 per share.

3. GOING-CONCERN ANALYSIS

Insignia was provided with the distribution history of the Partnership. In
addition, pro forma financial statements showing forecasts of Partnership cash
flows, expenses and potential distributions were also provided to us by the
Partnership for the period ending December 31, 2001.

The Going-Concern Analysis is intended to value the Partnership as a going-
concern assuming its current asset base. The most significant component of the
value of the Partnership as a going-concern is the distributions to the
partners, which are assumed to be equal to the cash flow from the Partnership's
real estate assets. For purposes of this analysis, the Properties' cash flows
were attributed values based on the Appraised Values.

An adjustment was made to give effect for the joint venture illiquidity that
would impact the Terminal Values of the joint venture Properties. This
adjustment was made for the joint venture Properties that were valued by Cushman
pursuant to the discounted cash flow methodology, by applying to the Terminal
Value the same Joint Venture Discount utilized by Cushman in determining the
appraised liquidation value and discounting it to the present utilizing the
Appraised Discount Rate. For joint venture Properties appraised under the direct
capitalization approach, an adjustment was made to give effect to the joint
venture illiquidity that would affect the implied Terminal Values of these
Properties. This value was then discounted to the present at 12%.

Consideration was also given for the non-real estate assets of the Partnership.
The net assets considered were the Assets and Liabilities cited on the Balance
Sheet as of September 30, 2000 included in the Form 10-Q of the Partnership for
the period ended September 30, 2000, and were included at the value set forth in
the Balance Sheet with the exception of the assets classified as Other Assets on
the Balance Sheet of the Partnership at September 30, 2000. The only Other
Assets included were those that were deemed to have value upon liquidation, i.e.
furniture fixtures & equipment and receivables.

                                       4

An adjustment was also made to reflect the going-concern reserve requirements. A
general reserve of $1,000,000 was to be maintained by the Partnership and then
liquidated upon termination of the Partnership. An adjustment was thus made
equal to the cost of maintaining this reserve. The net cost was assumed to be
12% of the reserve per annum. A further adjustment was made for anticipated
capital expenditures at properties that were valued under either the replacement
cost or direct capitalization approaches, as no capital reserves were considered
in the appraisals for these properties. The reserves were based on actual
anticipated capital requirements over the next five years as estimated by the
management of the Partnership, and were discounted to present from the
anticipated date of expenditure utilizing a discount rate of 5%. A 5% discount
rate was selected as it is the approximate rate at which the reserved funds are
expected to earn interest.

Finally, an adjustment was made for the cost of asset management fees and
administrative costs. The values of these costs were derived by discounting the
anticipated annual cost of these expenses for the life of the Partnership. The
capitalization rates employed were equal to the weighted average Appraised
Discount Rate/Appraised Cap Rate for the Properties.

The resulting range of values per proposed REIT share based on the Going-Concern
Analysis is indicated to be $32.14 to $36.25 per share.

4. CONVERSION AND COMPARABLE COMPANY ANALYSIS

The Conversion and Comparable Company Analysis endeavors to determine the range
of value for the proposed REIT's shares.

The methodology employed in determining the REIT's value consisted of applying
to the Projected Funds from Operations ("Projected FFO") of the REIT a range of
multiples (the "FFO Multiples") which are consistent with the FFO Multiples at
which comparable real estate investment trusts are currently trading in the
marketplace. Funds from Operations were calculated in accordance with the
guidelines set out by the National Association of Real Estate Investment Trusts
("NAREIT"). While no directly comparable companies were identified, by adjusting
and applying the median Projected FFO multiple for small-capitalization real
estate investment trusts, those with an implied market capitalization less than
$250 million, a range of reasonable FFO Multiples was established. The range of
FFO Multiples was determined to be 5.1 to 6.3.

The Projected FFO of the REIT is comprised of two components: (1) Pro-forma FFO
("Pro-Forma FFO") for the assets currently owned ("Current Assets") by the
Partnership and (2) Anticipated FFO ("Anticipated FFO") for assets projected to
be acquired by the REIT in the future ("New Assets").

The Pro-Forma FFO is based on the actual operating results of the Current Assets
for the 12 month period ending September 30, 2000, as adjusted for the
anticipated increase in Asset Management Fees resulting from the higher Adjusted
Appraisals as compared to the 1998 appraised values.

                                       5

<PAGE>

Anticipated FFO is based on the projected operating results of the New Assets,
as decreased by the rise in the asset management fees resulting from the
acquisition of the New Assets. The New Assets are assumed to be acquired in two
ways: (1) by utilizing all available cash less a reserve equal to 3% of the
Adjusted Appraisals to buy New Assets and (2) by leveraging the Current Assets
and the New Assets to a level of 75% with debt which carries an interest rate of
8%. The New Assets are assumed to generate net operating income equal to 10.5%
of their gross purchase price. The resulting range of values per proposed REIT
share based on the Conversion and Comparable Company Analysis are indicated to
be $31.55 to $38.98 per share.

The above analysis reflects the REIT's intention to leverage and grow its asset
base. By letter dated December 1, 2000 the Partnership asked us to prepare a
supplemental analysis estimating the low end of the value per REIT share if the
market values the REIT based solely on the Partnership's existing asset base.
For this analysis we applied a 5.358 multiple to Projected FFO of the REIT. The
Projected FFO of the REIT under this assumption is comprised of two components:
(1) Proforma FFO for the assets currently owned by the Partnership calculated
using the same method described above and (2) an anticipated excess cash
distribution which equals cash on hand at September 30, 2000 less projected
capital improvements and reserves. The 5.358 multiple represents the low end of
a range of multiples determined by applying a 6% margin of error to the median
Projected FFO Multiple for the set of real estate investment trusts described
above. The resulting value per proposed REIT share is indicated to be $21.82 per
share. Estimates of value of the proposed REIT shares are not intended and
should not be construed as a prediction of estimates as to the trading price of
the proposed REIT shares upon or after consummation of the Transaction.

The information set forth in this letter does not constitute and should not be
construed as a recommendation to any holder of Partnership Units with respect to
the proposed Transaction. The analyses do not address the merits of the proposed
Transaction or consider any alternatives to the proposed Transaction. This
letter has been prepared for the Partnership, and should not be reproduced,
summarized, described or referred to without the prior written consent of
Insignia; provided, however, that this letter may be summarized and reproduced
in full in the Registration Statement on Form S-4 to be filed by the
Partnership.

principal amount of $1,000 or any larger amount that is a multiple of $1,000 in
excess thereof for which such option has been exercised, shall be extended to
the Maturity Extension Date occurring in the month thirteen months following

the form entitled "Option to Extend Maturity" included below duly completed and,
in the event of an election to extend the maturity of only a portion of the

than the entire principal amount hereof provided that the principal amount for
which such option is not exercised is at least $1,000 or any larger amount that

     If the option to extend the maturity of any portion hereof is not duly
exercised within the Election Period for any such Election Date, a new Note or

extend has not been made and having as its or their "Maturity Date" (as such
term is used in each such Short-Term Note) the Maturity Extension Date occurring
in the month ten months after such Election Date shall be issued on such
Election Date in the name of the holder hereof, subject to delivery of this Note
to the Note Registrar, and Schedule I hereto shall be annotated as of such
Election Date to reflect the corresponding decrease in the principal amount
hereof. The failure to extend the maturity of all or any portion of this Note
will be irrevocable and will be binding upon any subsequent holder of this Note.

     The Company, the Elections Agent and the Trustee (upon notice from the

date, as the case may be (each an "interest period").

     The Calculation Agent will calculate the interest rate on this Note. The
Calculation Agent will reset the interest rate on each Interest Payment Date,
each of which shall be an "interest reset date." The interest rate for each
interest period will be equal to LIBOR plus or minus the Spread. The Spread for
each interest period will be as follows:

<TABLE>
<CAPTION>
FOR INTEREST RESET DATES OCCURRING                              SPREAD
----------------------------------                              ------

From December 14, 2000, to but excluding December 4, 2001...  Minus 0.02%
From December 4, 2001, to but excluding December 4, 2002....   Plus 0.01%
From December 4, 2002, to but excluding December 4, 2003....   Plus 0.04%
From December 4, 2003, to but excluding December 4, 2004....   Plus 0.06%
From December 4, 2004, to but excluding January 4, 2006.....   Plus 0.06%
</TABLE>

The interest rate in effect for the period from December 14, 2000 to but
excluding, March 4, 2001, the initial interest reset date, will be LIBOR, as
determined on December 12, 2000, minus 0.02%. The second London Business Day
preceding an interest reset date will be the "interest determination date" for
that interest reset date. The interest rate in effect on each day that is not an
interest reset date will be the interest rate determined as of the interest
determination date pertaining to the immediately preceding interest reset date.
The interest rate in effect on any day that is an interest reset date will be
the interest rate determined as of the interest determination date pertaining to
that interest reset date, except that the interest rate in effect for the period
from and including December 14, 2000 to the first interest reset date will be
the initial interest rate.

     The Calculation Agent will determine "LIBOR" in accordance with the
following provisions:

          (i) With respect to any interest determination date, LIBOR will be the
     rate for deposits in United States dollars having a maturity of three
     months commencing on the interest reset date that appears on Telerate Page
     3750 as of 11:00 A.M., London time, on that interest determination date;
     provided that with respect to the interest determination date for any final
     interest reset date, LIBOR will be the rate for deposits in United States
     dollars having a maturity of one month commencing on such final reset date.
     If no rate appears, LIBOR, in respect to that interest determination date,
     will be determined in accordance with the provisions described in (ii)
     below.

          (ii) With respect to an interest determination date on which no rate
     appears on Telerate Page 3750, as specified in (i) above, the Calculation
     Agent will request the principal London offices of each of four major
     reference banks in the London interbank market, as selected by the
     Calculation Agent, to provide the Calculation Agent with its offered
     quotation for deposits in United States dollars for the period of three
     months (or one month in the case of the interest determination date
     relating to any final interest reset date), commencing on the interest
     reset date, to prime banks in the London interbank market at approximately
     11:00 A.M., London time, on that interest determination date and in a
     principal amount that is representative for a single transaction in United
     States dollars in that market at that time. If at least two quotations are
     provided, then LIBOR on that interest determination date will be the
     arithmetic mean of those quotations. If fewer than two quotations are
     provided, then LIBOR on the interest determination date will be the
     arithmetic mean of the rates quoted at approximately 11:00 A.M., in The
     City of New York, on the interest determination date by three major banks
     in The City of New York selected by the Calculation Agent for loans in
     United States dollars to leading European banks, having a three-month
     maturity (or one month in the case of the interest determination date
     relating to any final interest reset date) and in a principal amount that
     is representative for a single transaction in United States dollars in that
     market at that time; provided, however, that if the banks selected by the
     Calculation Agent are not providing quotations in the manner described by
     this sentence, LIBOR determined as of that interest determination date will
     be LIBOR in effect on that interest determination date.

     "Telerate Page 3750" means the display designated as "Page 3750" on Bridge
Telerate, Inc., or any successor service, for the purpose of displaying the
London interbank rates of major banks for United States dollars.

     The Notes are not redeemable prior to maturity and are not entitled to any
sinking fund.

     In case an Event of Default with respect to this series of Notes, as
defined in the Indenture, shall have occurred and be continuing, the principal
hereof may be declared, and upon such declaration shall become, due and payable,
in the manner, with the effect and subject to the conditions provided in the
Indenture.

     Certain obligations of the Company hereunder and under the Indenture may be
defeased with the effects and subject to the conditions set forth therein.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than 66 2/3% in aggregate principal
amount of the Notes of this series at the time outstanding, evidenced as in the
Indenture provided, to execute supplemental indentures adding any provisions to
or changing in any manner or eliminating any of the provisions of the Indenture
or of any supplemental indenture or modifying in any manner the rights of the
holders of the Notes of this series; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any such Notes, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Note so affected, or (ii)
reduce the aforesaid percentage of Notes, the consent of the holders of which is
required for any such supplemental indenture, without the consent of the holders
of all Notes of this series then outstanding. It is also provided in the
Indenture that, under certain circumstances, the holders of a majority in
aggregate principal amount of such Notes at the time outstanding may on behalf
of the holders of all of such Notes waive any past default under the Indenture
and its consequences, except a default in the payment of the principal of (or
premium, if any) or interest on any of such Notes. Any such consent or waiver by
the holder of any Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Note and of any Note issued upon the transfer thereof or in exchange or
substitution therefor, irrespective of whether or not any notation of such
consent or waiver is made upon such Note or such other Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the times, place and rate, and in the coin or currency herein prescribed.

     The Notes are issuable only as registered Notes without coupon in
denominations of $1,000 or any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof and in the manner and
subject to the limitations provided in the Indenture, Notes may be exchanged for
a like aggregate principal amount of Notes of other denominations.

     Upon due presentment for registration of transfer of this Note at the
office or agency of the Note Registrar in New York, New York, a new Note or
Notes of this series, of authorized denominations, for a like aggregate
principal amount, will be issued to the transferee as provided in the Indenture.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

     The Company, the Trustee, the Paying Agent and the Note Registrar may deem
and treat the holder hereof as the absolute owner hereof (whether or not this
Note shall be overdue and notwithstanding any notation of ownership or other
writing hereon) for the purpose of receiving payment of or on account of the
principal hereof (and premium, if any) and, subject to the provisions on the
face hereof, interest hereon, and for all other purposes, and neither the
Company nor the Trustee nor the Paying Agent nor the Note Registrar shall be
affected by any notice to the contrary.

     No recourse shall be had for the payment of the principal of (or premium,
if any) or the interest on this Note, or for any claim based hereon, or
otherwise in respect hereof, or based on or in respect of the Indenture or any
indenture supplemental thereto, against any incorporator, shareholder, officer
or director, as such, past, present or future, of the Company or of any
successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

     This Note shall be deemed to be a contract made under the laws of the State
of New York and for all purposes shall be construed in accordance with the laws
of said State.

Notes). Capitalized terms used but not defined herein shall have the respective
meanings assigned to them in the Indenture. This is one of the Notes
representing the series created by the Supplemental Indenture, dated December

Securities(SM) (EXLs(SM)) (the "Notes"). The terms of the Notes include those
stated in the Indenture and those made part of the Indenture by reference to the
Trust Indenture Act of 1939.

     This Note has been issued pursuant to the terms of a predecessor Note
originally issued on December 14, 2000 (the "Predecessor Note") and is a
"Short-Term Note" as defined in the Predecessor Note. This Note may not be
exchanged for an interest in the Predecessor Note.

     The following definitions shall be applicable to the Notes:

     "Authenticating Agent" shall mean The Bank of New York, or any successor
thereto.

     "Business Day" shall mean any day except a Saturday, Sunday or a legal
holiday in The City of New York on which banking institutions are authorized or
required by law, regulation or executive order to close; provided that the day
is also a London Business Day.

     "Calculation Agent" shall mean The Bank of New York, or any successor
thereto.

     "Interest Payment Date" shall mean the fourth day of each March, June,
September and December. The final Interest Payment Date for this Note shall be
the maturity date and interest for the final interest period will accrue from
and including the Interest Payment Date immediately preceding such maturity date
to but excluding the maturity date.

dollars are transacted in the London interbank market.

     "Note Registrar" shall mean The Bank of New York, or any successor thereto.

     The Calculation Agent will calculate the interest rate on this Note. The
Calculation Agent will reset the interest rate on each Interest Payment Date,
each of which shall be an "interest reset date." The interest rate for each
interest period will be equal to LIBOR plus or minus the Spread. The Spread for
each interest period will be as follows:

<TABLE>
<CAPTION>
FOR INTEREST RESET DATES OCCURRING                              SPREAD
----------------------------------                            ----------
<S>                                                           <C>
From December 14, 2000, to but excluding December 4, 2001...  Minus 0.02%
From December 4, 2001, to but excluding December 4, 2002....   Plus 0.01%
From December 4, 2002, to but excluding December 4, 2003....   Plus 0.04%
From December 4, 2003, to but excluding December 4, 2004....   Plus 0.06%
From December 4, 2004, to but excluding January 4, 2006.....   Plus 0.06%
</TABLE>

The second London Business Day preceding an interest reset date will be the
"interest determination date" for that interest reset date. The interest rate in
effect on each day that is not an interest reset date will be the interest rate
determined as of the interest determination date pertaining to the immediately
preceding interest reset date. The interest rate in effect on any day that is an
interest reset date will be the interest rate determined as of the interest
determination date pertaining to that interest reset date.

     The Calculation Agent will determine "LIBOR" in accordance with the
following provisions:

          (i) With respect to any interest determination date, LIBOR will be the
     rate for deposits in United States dollars having a maturity of three
     months commencing on the interest reset date that appears on Telerate Page
     3750 as of 11:00 A.M., London time, on that interest determination date;
     provided that with respect to the interest determination date for any final
     interest reset date, LIBOR will be the rate for deposits in United States
     dollars having a maturity of one month commencing on such final reset date.
     If no rate appears, LIBOR, in respect to that interest determination date,
     will be determined in accordance with the provisions described in (ii)
     below.

          (ii) With respect to an interest determination date on which no rate
     appears on Telerate Page 3750, as specified in (i) above, the Calculation
     Agent will request the principal London offices of each of four major
     reference banks in the London interbank market, as selected by the
     Calculation Agent, to provide the Calculation Agent with its offered
     quotation for deposits in United States dollars for the period of three
     months (or one month in the case of the interest determination date
     relating to any final interest reset date), commencing on the interest
     reset date, to prime banks in the London interbank market at approximately
     11:00 A.M., London time, on that interest determination date and in a
     principal amount that is representative for a single transaction in United
     States dollars in that market at that time. If at least two quotations are
     provided, then LIBOR on that interest determination date will be the
     arithmetic mean of those quotations. If fewer than two quotations are
     provided, then LIBOR on the interest determination date will be the
     arithmetic mean of the rates quoted at approximately 11:00 A.M., in The
     City of New York, on the interest determination date by three major banks
     in The City of New York selected by the Calculation Agent for loans in
     United States dollars to leading European banks, having a three-month
     maturity (or one month in the case of the interest determination date
     relating to any final interest reset date) and in a principal amount that
     is representative for a single transaction in United States dollars in that
     market at that time; provided, however, that if the banks selected by the
     Calculation Agent are not providing quotations in the manner described by
     this sentence, LIBOR determined as of that interest determination date will
     be LIBOR in effect on that interest determination date.

     "Telerate Page 3750" means the display designated as "Page 3750" on Bridge
Telerate, Inc., or any successor service, for the purpose of displaying the
London interbank rates of major banks for United States dollars.

     The Notes are not redeemable prior to maturity and are not entitled to any
sinking fund.

     In case an Event of Default with respect to this series of Notes, as
defined in the Indenture, shall have occurred and be continuing, the principal
hereof may be declared, and upon such declaration shall become, due and payable,
in the manner, with the effect and subject to the conditions provided in the
Indenture.

     Certain obligations of the Company hereunder and under the Indenture may be
defeased with the effects and subject to the conditions set forth therein.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than 66 2/3% in aggregate principal
amount of the Notes of this series at the time outstanding, evidenced as in the
Indenture provided, to execute supplemental indentures adding any provisions to
or changing in any manner or eliminating any of the provisions of the Indenture
or of any supplemental indenture or modifying in any manner the rights of the
holders of the Notes of this series; provided, however, that no such
supplemental indenture shall (i) extend the fixed maturity of any such Notes, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any premium payable upon the redemption
thereof, without the consent of the holder of each Note so affected, or (ii)
reduce the aforesaid percentage of Notes, the consent of the holders of which is
required for any such supplemental indenture, without the consent of the holders
of all Notes of this series then outstanding. It is also provided in the
Indenture that, under certain circumstances, the holders of a majority in
aggregate principal amount of such Notes at the time outstanding may on behalf
of the holders of all of such Notes waive any past default under the Indenture
and its consequences, except a default in the payment of the principal of (or
premium, if any) or interest on any of such Notes. Any such consent or waiver by
the holder of any Note (unless revoked as provided in the Indenture) shall be
conclusive and binding upon such holder and upon all future holders and owners
of such Note and of any Note issued upon the transfer thereof or in exchange or
substitution therefor, irrespective of whether or not any notation of such
consent or waiver is made upon such Note or such other Note.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of and interest on this Note at
the times, place and rate, and in the coin or currency herein prescribed.

     The Notes are issuable only as registered Notes without coupon in
denominations of $1,000 or any integral multiple of $1,000. At the office or
agency of the Company referred to on the face hereof and in the manner and
subject to the limitations provided in the Indenture, Notes may be exchanged for
a like aggregate principal amount of Notes of other denominations.

     Upon due presentment for registration of transfer of this Note at the
office or agency of the Note Registrar in New York, New York, a new Note or
Notes of this series, of authorized denominations, for a like aggregate
principal amount, will be issued to the transferee as provided in the Indenture.
No service charge shall be made for any such transfer, but the Company may
require payment of a sum sufficient to cover any tax or other governmental
charge that may be imposed in relation thereto.

     The Company, the Trustee, the Paying Agent and the Note Registrar may deem
and treat the holder hereof as the absolute owner hereof (whether or not this
Note shall be overdue and notwithstanding any notation of ownership or other
writing hereon) for the purpose of receiving payment of or on account of the
principal hereof (and premium, if any) and, subject to the provisions on the
face hereof, interest hereon, and for all other purposes, and neither the
Company nor the Trustee nor the Paying Agent nor the Note Registrar shall be
affected by any notice to the contrary.

     No recourse shall be had for the payment of the principal of (or premium,
if any) or the interest on this Note, or for any claim based hereon, or
otherwise in respect hereof, or based on or in respect of the Indenture or any
indenture supplemental thereto, against any incorporator, shareholder, officer
or director, as such, past, present or future, of the Company or of any
successor corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

     This Note shall be deemed to be a contract made under the laws of the State
of New York and for all purposes shall be construed in accordance with the law
of said State.
