FOR VALUE RECEIVED, FIRST STATES INVESTORS 4000B, LLC, a Delaware limited
liability company, having its principal office at 1725 The Fairway, Jenkintown,
Pennsylvania 19046 (hereinafter referred to as "Maker"), promises to pay to the
order of LEHMAN BROTHERS BANK, FSB, having its principal place of business at
745 Seventh Avenue, New York, New York 10019 (hereinafter referred to as
"Payee"), or at such place as the holder hereof may from time to time designate
in writing, the principal sum of ________________________ DOLLARS ($ ) in lawful
money of the United States of America with interest thereon to be computed on
the unpaid principal balance from time to time outstanding at the Applicable
Interest Rate (hereinafter defined), and to be paid in installments as follows:

1.   A payment of interest only from and including the date hereof to June 10,
     2003 shall be payable on June 10, 2003.

2.   Consecutive quarterly payments of principal and interest, as set forth in
     Schedule A attached hereto and made a part hereof, beginning on September
     10, 2003 and continuing thereafter on the tenth day of each March, June,
     September and December thereafter (or if such day is not a Business Day,
     then on the next succeeding Business Day) to and including June 10, 2023
     (each such quarterly due date, a "Payment Date") . Interest hereon shall be
     calculated on the basis of a three hundred sixty (360) day year and the
     actual number of days elapsed in such period. The term "Business Day" shall
     mean a weekday except a legal holiday or a day on which banking
     institutions in New York or Utah are authorized by law to be closed.

3.   Any balance of said principal sum, together with any accrued and unpaid
     interest thereon, shall be due and payable on June 10, 2023 (the "Maturity
     Date").

The term "Applicable Interest Rate" shall mean from the date of this Note
through and including the Maturity Date, a rate of 5.496 % per annum.

The whole of the principal sum of this Note, together with all interest accrued
and unpaid thereon, the Prepayment Consideration (as hereinafter defined) and
all other sums secured by or due under the Security Instrument (hereinafter
defined) and this Note (all such sums hereinafter collectively referred to as
the "Debt") shall without notice become immediately due and payable at the
option of Payee if any payment required in this Note is not paid when due or on
the happening of any other default, after the expiration of any applicable
notice and grace periods, herein or under the terms of the Security Instrument
or the other Loan Documents (hereinafter defined) (hereinafter collectively an
"Event of Default"). All of the terms, covenants and conditions contained in the
Security Instrument and the other Loan Documents are hereby made

                                        1

<PAGE>

part of this Note to the same extent and with the same force as if they were
fully set forth herein. In the event that it should become necessary to employ
counsel to collect or enforce the Debt or to protect or foreclose the security
therefor, Maker also shall pay on demand all reasonable costs of collection
incurred by Payee, including reasonable attorneys' fees and costs reasonably
incurred for the services of counsel and counsel's employees whether or not suit
be brought.

This Note may not be prepaid at the option of the Maker except as expressly
provided herein or in the Security Instrument, as hereinafter defined. This Note
may be prepaid in whole but not in part at any time following May 1, 2004, upon
thirty (30) days' prior written notice to Payee, provided that such payment
shall include Prepayment Consideration (hereinafter defined) on the principal
amount hereof and other amounts in accordance with the following paragraph, and
provided that Maker simultaneously prepays all other notes it has issued to
Payee. In addition, on and after May 1, 2004, Maker may defease this Note in
whole (but not in part) in accordance with the terms of the Defeasance Rider
attached hereto and made a part hereof, whether or not it simultaneously
defeases any other note. This Note is subject to mandatory prepayment as
provided in the Security Instrument.

If, following the occurrence and during the continuation of any Event of
Default, Maker shall tender payment of an amount sufficient to satisfy the Debt
at any time prior to a sale of the Mortgaged Property, either through
foreclosure or the exercise of the other remedies available to Payee under the
Security Instrument, such tender by Maker shall be deemed to be a voluntary
prepayment under this Note in the amount tendered. Accordingly, Maker agrees
that it shall, in addition to the outstanding principal balance of this Note,
also pay to Payee a sum equal to (a) interest accrued and unpaid on the
principal balance of this Note to the date of such tender (the "Determination
Date"), (b) a "make whole amount" (the "Prepayment Consideration") determined as
hereinafter provided, and (c) all other amounts then due and payable under this
Note, the Security Instrument and the other Loan Documents. The Prepayment
Consideration shall be the greater of 1% of the then outstanding principal
amount hereof and the amount determined as follows: an amount equal to (x) the
sum of the amounts representing the present values of each remaining scheduled
payment which would be payable with respect to the Note following such
prepayment, such sum to be determined by discounting (monthly on the basis of a
360-day year composed of twelve 30-day months) each such amount utilizing a
discount factor equal to the Reinvestment Yield, less (y) the principal amount
of the Note, but in no event less than 0. "Reinvestment Yield" means 25 basis
points plus the yield to maturity of either (i) the yield reported as of 11:00
A.M. (New York City time) on the date of calculation on the display designated
USD on the Bloomberg Financial Markets Screen (or such other display as may
replace such displays on the Bloomberg service or any other generally available
service) for actively traded U.S. Treasury securities (or, if unavailable,
whatever standard benchmark is used for such purposes by institutional
investors) having a constant maturity equal to the remaining average life of the
Note, or (ii) if such yields shall not be reported as of such time or the yields
reported as of such time shall not be ascertainable (including by way of
interpolation), the Treasury Constant Maturity Series yields (or, if
unavailable, whatever standard benchmark is used for such purposes by
institutional investors) reported for the latest day for which such yields shall
have been so reported as of the Business Day next preceding the Determination
Date in Federal Reserve Statistical Release H-15 (519) (or any comparable
successor publication) for U.S. Treasury securities (or, if unavailable,
whatever standard benchmark is used for such purposes by institutional
investors) having a constant maturity equal to the remaining average

                                        2

<PAGE>

life of the Note as of the Determination Date; provided, however, if no maturity
exactly corresponding to the remaining average life of the Note shall appear
therein, yields for the two most closely corresponding reported maturities (with
one being shorter and the other longer) shall be calculated pursuant to the
foregoing sentence and the Reinvestment Yield shall be interpolated from such
yields on a straight-line basis (rounding in each of such relevant periods, to
the nearest month). All such prepayments must occur on a Business Day.

Maker does hereby agree that upon the failure to make any payment required by
this Note on the scheduled due date (or if such date is not a Business Day, then
on the next Business Day), interest on such delinquent amount shall be accrued
and be due and payable at a rate (the "Default Rate") equal to the lesser of (i)
two percent (2%) over the Applicable Interest Rate, and (ii) the highest rate
allowed by applicable law. The Default Rate shall be computed from the due date
of the delinquent payment to the actual receipt and collection of such payment.
This charge shall be added to the Debt, and shall be deemed secured by the
Security Instrument. This paragraph, however, shall not be construed as an
agreement or privilege to extend the date of the payment of the Debt or any
payment hereunder, nor as a waiver of any other right or remedy accruing to
Payee by reason of the occurrence of any such delinquency.

The term "Security Instrument" as used in this Note shall mean the Mortgage,
Security Agreement and Assignment of Leases and Rents dated as of even date
herewith given by Maker for the use and benefit of Payee covering the fee estate
of Maker in certain premises described therein (the "Mortgaged Property"). The
term "Loan Documents" as used in this Note shall mean all and any of the
documents now or hereafter executed by Maker and/or others and by or in favor of
Payee, which wholly or partially evidence, secure or guarantee payment of this
Note. Whenever used, the singular number shall include the plural, the plural
number shall include the singular, and the words "Payee" and "Maker" shall
include their respective successors, assigns, heirs, executors and
administrators.

This Note is subject to the express condition that at no time shall Maker be
obligated or required to pay interest on the Debt at a rate which could subject
Payee to either civil or criminal liability as a result of being in excess of
the maximum interest rate which Maker is permitted by applicable law to contract
or agree to pay (the "Maximum Rate"). If, from any circumstance whatsoever,
performance or fulfillment of any provision hereof, of the Security Instrument
or of any of the other Loan Documents or of any agreement between Maker and
Payee shall, at the time of the execution and delivery thereof or at the time
performance of such provision shall be due, involve or purport to require any
payment in excess of the limits prescribed by law, the obligation to be
performed or fulfilled shall be reduced automatically to the limit of such
validity without the necessity of execution of any amendment or new document.
Or, if, from any circumstance whatsoever, Payee shall ever receive anything of
value deemed interest under applicable law which would exceed interest at the
Maximum Rate, an amount equal to any amount which would have been excessive
interest shall be applied to the reduction of the outstanding principal balance
of this Note, and any excess shall be refunded to Maker. All sums contracted
for, charged, paid or agreed to be paid to Payee for the use, forbearance or
detention of the indebtedness of Maker to Payee shall, to the extent permitted
by applicable law, be amortized, prorated, allocated, and spread throughout the
full stated term of such indebtedness so that the amount of interest on account
of such indebtedness does not exceed the Maximum Rate. The provisions of this
paragraph shall control all existing and future agreements between Maker

                                        3

<PAGE>

and Payee with respect to the Loan Documents.

This Note may not be modified, amended, waived, extended, changed, discharged or
terminated orally or by any act or failure to act on the part of Maker or Payee,
but only by an agreement in writing signed by the party against whom enforcement
of any modification, amendment, waiver, extension, change, discharge or
termination is sought.

Maker and all others who may become liable for the payment of all or any part of
the Debt do hereby severally waive presentment and demand for payment, notice of
dishonor, protest, notice of protest, notice of non-payment, and notice of
intent to accelerate the maturity hereof (and of such acceleration). No release
of any security for the Debt or extension of time for payment of this Note or
any installment hereof, and no alteration, amendment or waiver of any provision
of this Note, the Security Instrument or the other Loan Documents made by
agreement between Payee and any other person or party (other than Maker) shall
release, modify, amend, waive, extend, change, discharge, terminate or affect
the liability of Maker, and any other who may become liable for the payment of
all or any part of the Debt, under this Note, the Security Instrument or the
other Loan Documents.

Notwithstanding anything to the contrary contained in this Note, the liability
of Maker (and its trustees, beneficial owners, members, managers, directors,
officers, partners and other Released Parties (as defined in the Security
Instrument)) for the Debt and for the performance of the other agreements,
covenants and obligations contained herein, in the Security Instrument and the
other Loan Documents shall be limited as set forth in paragraph 51 of the
Security Instrument.

Notwithstanding anything to the contrary in this Note, the Security Instrument
or any of the other Loan Documents, Payee shall not be deemed to have waived any
right which Payee may have under Section 506(a), 506(b), 1111(b) or any other
provisions of the U.S. Bankruptcy Code to file a claim for the full amount of
the Debt secured by the Security Instrument or to require that all collateral
shall continue to secure all of the Debt owing to Payee in accordance with this
Note, the Security Instrument or any of the other Loan Documents.

Maker represents that Maker has full power, authority and legal right to
execute, deliver and perform its obligations pursuant to this Note, the Security
Instrument and the other Loan Documents and that this Note, the Security
Instrument and the other Loan Documents constitute valid and binding obligations
of Maker, subject to applicable laws.

All notices or other communications required or permitted to be given pursuant
hereto shall be given in the manner specified in the Security Instrument
directed to the parties at their respective addresses as provided therein.

TO THE EXTENT PERMITTED BY LAW, MAKER AND PAYEE EACH HEREBY AGREES NOT TO ELECT
A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY JURY, AND WAIVES ANY RIGHT TO
TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER

DOCUMENTS, OR ANY CLAIM, COUNTERCLAIM OR OTHER ACTION ARISING IN CONNECTION
THEREWITH. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY

                                        4

      approval of Payee, and the Maker shall transfer and assign all

      of this Defeasance Rider, which such taxes Payee shall cause to be paid to
      the appropriate taxing authority on the Release Date;

(ii)  The term "U.S. Obligations" shall mean "government securities" as such

option of Payee if any payment required in this Note is not paid when due or on
the happening of any other default, after the expiration of any applicable
notice and grace periods, herein or under the terms of the Security Instrument
or the other Loan Documents (hereinafter defined) (hereinafter collectively an
"Event of Default"). All of the terms, covenants and conditions contained in the
Security Instrument and the other Loan Documents are hereby made

                                        1

part of this Note to the same extent and with the same force as if they were
fully set forth herein. In the event that it should become necessary to employ
counsel to collect or enforce the Debt or to protect or foreclose the security
therefor, Maker also shall pay on demand all reasonable costs of collection
incurred by Payee, including reasonable attorneys' fees and costs reasonably
incurred for the services of counsel and counsel's employees whether or not suit
be brought.

This Note may not be prepaid at the option of the Maker except as expressly
provided herein or in the Security Instrument, as hereinafter defined. This Note
may be prepaid in whole but not in part at any time following May 1, 2004, upon
thirty (30) days' prior written notice to Payee, provided that such payment
shall include Prepayment Consideration (hereinafter defined) on the principal
amount hereof and other amounts in accordance with the following paragraph, and
provided that Maker simultaneously prepays all other notes it has issued to
Payee. In addition, on and after May 1, 2004, Maker may defease this Note in
whole (but not in part) in accordance with the terms of the Defeasance Rider
attached hereto and made a part hereof, whether or not it simultaneously
defeases any other note. This Note is subject to mandatory prepayment as
provided in the Security Instrument.

If, following the occurrence and during the continuation of any Event of
Default, Maker shall tender payment of an amount sufficient to satisfy the Debt
at any time prior to a sale of the Mortgaged Property, either through
foreclosure or the exercise of the other remedies available to Payee under the
Security Instrument, such tender by Maker shall be deemed to be a voluntary
prepayment under this Note in the amount tendered. Accordingly, Maker agrees
that it shall, in addition to the outstanding principal balance of this Note,
also pay to Payee a sum equal to (a) interest accrued and unpaid on the
principal balance of this Note to the date of such tender (the "Determination
Date"), (b) a "make whole amount" (the "Prepayment Consideration") determined as
hereinafter provided, and (c) all other amounts then due and payable under this
Note, the Security Instrument and the other Loan Documents. The Prepayment
Consideration shall be the greater of 1% of the then outstanding principal
amount hereof and the amount determined as follows: an amount equal to (x) the
sum of the amounts representing the present values of each remaining scheduled
payment which would be payable with respect to the Note following such
prepayment, such sum to be determined by discounting (monthly on the basis of a
360-day year composed of twelve 30-day months) each such amount utilizing a
discount factor equal to the Reinvestment Yield, less (y) the principal amount
of the Note, but in no event less than 0. "Reinvestment Yield" means 25 basis
points plus the yield to maturity of either (i) the yield reported as of 11:00
A.M. (New York City time) on the date of calculation on the display designated
USD on the Bloomberg Financial Markets Screen (or such other display as may
replace such displays on the Bloomberg service or any other generally available
service) for actively traded U.S. Treasury securities (or, if unavailable,
whatever standard benchmark is used for such purposes by institutional
investors) having a constant maturity equal to the remaining average life of the
Note, or (ii) if such yields shall not be reported as of such time or the yields
reported as of such time shall not be ascertainable (including by way of
interpolation), the Treasury Constant Maturity Series yields (or, if
unavailable, whatever standard benchmark is used for such purposes by
institutional investors) reported for the latest day for which such yields shall
have been so reported as of the Business Day next preceding the Determination
Date in Federal Reserve Statistical Release H-15 (519) (or any comparable
successor publication) for U.S. Treasury securities (or, if unavailable,
whatever standard benchmark is used for such purposes by institutional
investors) having a constant maturity equal to the remaining average

                                        2

<PAGE>

life of the Note as of the Determination Date; provided, however, if no maturity
exactly corresponding to the remaining average life of the Note shall appear
therein, yields for the two most closely corresponding reported maturities (with
one being shorter and the other longer) shall be calculated pursuant to the
foregoing sentence and the Reinvestment Yield shall be interpolated from such
yields on a straight-line basis (rounding in each of such relevant periods, to
the nearest month). All such prepayments must occur on a Business Day.

Maker does hereby agree that upon the failure to make any payment required by
this Note on the scheduled due date (or if such date is not a Business Day, then
on the next Business Day), interest on such delinquent amount shall be accrued
and be due and payable at a rate (the "Default Rate") equal to the lesser of (i)
two percent (2%) over the Applicable Interest Rate, and (ii) the highest rate
allowed by applicable law. The Default Rate shall be computed from the due date
of the delinquent payment to the actual receipt and collection of such payment.
This charge shall be added to the Debt, and shall be deemed secured by the
Security Instrument. This paragraph, however, shall not be construed as an
agreement or privilege to extend the date of the payment of the Debt or any
payment hereunder, nor as a waiver of any other right or remedy accruing to
Payee by reason of the occurrence of any such delinquency.

The term "Security Instrument" as used in this Note shall mean the Mortgage,
Security Agreement and Assignment of Leases and Rents dated as of even date
herewith given by Maker for the use and benefit of Payee covering the fee estate
of Maker in certain premises described therein (the "Mortgaged Property"). The
term "Loan Documents" as used in this Note shall mean all and any of the
documents now or hereafter executed by Maker and/or others and by or in favor of
Payee, which wholly or partially evidence, secure or guarantee payment of this
Note. Whenever used, the singular number shall include the plural, the plural
number shall include the singular, and the words "Payee" and "Maker" shall
include their respective successors, assigns, heirs, executors and
administrators.

This Note is subject to the express condition that at no time shall Maker be
obligated or required to pay interest on the Debt at a rate which could subject
Payee to either civil or criminal liability as a result of being in excess of
the maximum interest rate which Maker is permitted by applicable law to contract
or agree to pay (the "Maximum Rate"). If, from any circumstance whatsoever,
performance or fulfillment of any provision hereof, of the Security Instrument
or of any of the other Loan Documents or of any agreement between Maker and
Payee shall, at the time of the execution and delivery thereof or at the time
performance of such provision shall be due, involve or purport to require any
payment in excess of the limits prescribed by law, the obligation to be
performed or fulfilled shall be reduced automatically to the limit of such
validity without the necessity of execution of any amendment or new document.
Or, if, from any circumstance whatsoever, Payee shall ever receive anything of
value deemed interest under applicable law which would exceed interest at the
Maximum Rate, an amount equal to any amount which would have been excessive
interest shall be applied to the reduction of the outstanding principal balance
of this Note, and any excess shall be refunded to Maker. All sums contracted
for, charged, paid or agreed to be paid to Payee for the use, forbearance or
detention of the indebtedness of Maker to Payee shall, to the extent permitted
by applicable law, be amortized, prorated, allocated, and spread throughout the
full stated term of such indebtedness so that the amount of interest on account
of such indebtedness does not exceed the Maximum Rate. The provisions of this
paragraph shall control all existing and future agreements between Maker

                                        3

and Payee with respect to the Loan Documents.

This Note may not be modified, amended, waived, extended, changed, discharged or
terminated orally or by any act or failure to act on the part of Maker or Payee,
but only by an agreement in writing signed by the party against whom enforcement
of any modification, amendment, waiver, extension, change, discharge or
termination is sought.

Maker and all others who may become liable for the payment of all or any part of
the Debt do hereby severally waive presentment and demand for payment, notice of
dishonor, protest, notice of protest, notice of non-payment, and notice of
intent to accelerate the maturity hereof (and of such acceleration). No release
of any security for the Debt or extension of time for payment of this Note or
any installment hereof, and no alteration, amendment or waiver of any provision
of this Note, the Security Instrument or the other Loan Documents made by
agreement between Payee and any other person or party (other than Maker) shall
release, modify, amend, waive, extend, change, discharge, terminate or affect
the liability of Maker, and any other who may become liable for the payment of
all or any part of the Debt, under this Note, the Security Instrument or the
other Loan Documents.

Notwithstanding anything to the contrary contained in this Note, the liability
of Maker (and its trustees, beneficial owners, members, managers, directors,
officers, partners and other Released Parties (as defined in the Security
Instrument)) for the Debt and for the performance of the other agreements,
covenants and obligations contained herein, in the Security Instrument and the
other Loan Documents shall be limited as set forth in paragraph 51 of the
Security Instrument.

Notwithstanding anything to the contrary in this Note, the Security Instrument
or any of the other Loan Documents, Payee shall not be deemed to have waived any
right which Payee may have under Section 506(a), 506(b), 1111(b) or any other
provisions of the U.S. Bankruptcy Code to file a claim for the full amount of
the Debt secured by the Security Instrument or to require that all collateral
shall continue to secure all of the Debt owing to Payee in accordance with this
Note, the Security Instrument or any of the other Loan Documents.

Maker represents that Maker has full power, authority and legal right to
execute, deliver and perform its obligations pursuant to this Note, the Security
Instrument and the other Loan Documents and that this Note, the Security
Instrument and the other Loan Documents constitute valid and binding obligations
of Maker, subject to applicable laws.

All notices or other communications required or permitted to be given pursuant
hereto shall be given in the manner specified in the Security Instrument
directed to the parties at their respective addresses as provided therein.

TO THE EXTENT PERMITTED BY LAW, MAKER AND PAYEE EACH HEREBY AGREES NOT TO ELECT
A TRIAL BY JURY OF ANY ISSUE TRIABLE OF RIGHT BY JURY, AND WAIVES ANY RIGHT TO
TRIAL BY JURY FULLY TO THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER
EXIST WITH REGARD TO THIS NOTE, THE SECURITY INSTRUMENT OR THE OTHER LOAN
DOCUMENTS, OR ANY CLAIM, COUNTERCLAIM OR OTHER ACTION ARISING IN CONNECTION
THEREWITH. THIS WAIVER OF RIGHT TO TRIAL BY JURY IS GIVEN KNOWINGLY

                    the Mortgaged Property is located and such financing
                    statements are filed, respectively, which Payee agrees to
                    execute, notarize and deliver upon the Release Date upon

                    Rider;

                    an officer's certificate of Maker certifying that the
                    requirements to be performed by Maker or to be delivered by

                    may reasonably request; and,

                    payment to Payee by Maker of all costs and expenses incurred

          Date) and in amounts equal to the scheduled payments due on such dates

(B)   Upon compliance with the requirements of this Defeasance Rider, the
      Mortgaged Property shall be released from the lien of the Security
      Instrument, any guarantor or indemnitor for the loan evidenced by the Note
      shall be released from any liability accruing after the date of compliance
      with this Defeasance Rider, and the pledged U.S. Obligations shall be the
      sole source of collateral securing this Note. Any portion of the
      Defeasance Deposit in excess of the amount necessary to purchase the U.S.

      obligations under this paragraph shall be remitted to the Maker with the
      release of the Mortgaged Property from the lien of the Security
      Instrument. In connection with such release, Maker shall establish, or
      designate a successor entity (the "Successor Maker"), subject to the
      approval of Payee, and the Maker shall transfer and assign all
      obligations, rights and duties under and to this Note together with the
      pledged U.S. Obligations to such Successor Maker. The obligation of Maker,
      subject to the approval of Payee, to establish or designate a Successor
      Maker shall be automatically deemed to be assumed by the transferee in the
      event of any sale or transfer of this Note and the other Loan Documents,
      and following such sale or transfer, the transferor shall be relieved of
      such obligation hereunder. The Maker shall pay $1,000 to any such
      Successor Maker as consideration for assuming the obligations under this
      Note and the Security Agreement. Notwithstanding anything in the other
      Loan Documents to the contrary, no other assumption fee shall be payable
      upon a transfer of this Note in accordance with this paragraph.

(C)   For purposes of this Defeasance Rider, the following terms shall have the
      following meanings:

(i)   The term "Defeasance Deposit" shall mean an amount which Payee shall
      determine in its reasonable and good faith discretion (in reliance upon a
      verification report delivered by a nationally recognized independent
      certified public accountant or firm of nationally recognized certified
      public accountants) is sufficient to pay the Scheduled Defeasance
      Payments, any costs and expenses (including the reasonable fee and
      expenses of such accountant or firm of accountants) incurred or to be
      incurred in the purchase of U.S. Obligations necessary to meet the
      Scheduled Defeasance Payments and any revenue, documentary stamp or
      intangible taxes or any other tax or charge due in connection with the
      transfer of this Note or otherwise required to accomplish the agreements
      of this Defeasance Rider, which such taxes Payee shall cause to be paid to
      the appropriate taxing authority on the Release Date;

(ii)  The term "U.S. Obligations" shall mean "government securities" as such
      term is defined in Section 2(a)(16) of the Investment Company Act of 1940,
      as amended (15 U.S.C. 80a-1, et seq.), that are not subject to prepayment,
      call or early redemption, and are maintained in the form of entries on the
      books of the Federal Reserve Bank.
