                        7.125% NOTE DUE DECEMBER 1, 2006


         SPIEKER PROPERTIES, L.P., a California limited partnership (the
"Issuer"), for value received, hereby promises to pay to Cede & Co., or
registered assignee (the "Holder"), upon presentation, the principal sum of
$100,000,000 on December 1, 2006, and to pay interest on the outstanding
principal amount thereon from December 10, 1996, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on December 1 and June 1 in each year (each an
"Interest Payment Date"), commencing June 1, 1997, and at the Stated Maturity,
at the rate of 7.125% per annum, computed on the basis of a 360-day year
comprised of twelve 30-day months, until the entire principal amount hereof is
paid or duly provided for. The interest so payable, and punctually paid or duly
provided for on any Interest Payment Date will, as provided in the Indenture
(hereinafter defined), be paid to the person in whose name this Note (the "2006
Note") (or one or more predecessor 2006 Notes) is registered at the close of
business on the Regular Record Date for such Interest Payment Date which shall
be the 15th calendar day preceding the applicable Interest Payment Date. Any
such interest not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date, and may either be paid
to the Person in whose name this 2006 Note (or one or more predecessor 2006
Notes) is registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest to be fixed by the Trustee, notice whereof
shall be given to Holders of 2006 Notes not more than 15 days and not less than
10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the 2006 Notes may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Payments
of the principal of, and interest on, this 2006 Note will be made at the office
or agency of the Trustee (hereinafter defined) maintained for that purpose at


                                       1
<PAGE>   2

Two International Place, Boston, Massachusetts 02110, or elsewhere as provided
in the Indenture, in United States Dollars; provided, however, that at the
option of the Holder hereof, and upon written notice to the Trustee of not less
than five Business Days prior to the applicable Interest Payment Date, payment
of interest may be made by (i) check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register kept for
the 2006 Notes pursuant to Section 305 of the Indenture (the "2006 Note
Register") or (ii) transfer to an account of the Person entitled thereto located
inside the United States.

         This 2006 Note is one of a fully authorized issue of securities of the
Issuer issued as a series of securities issued and to be issued under an
Indenture, dated as of December 6, 1995 and the Sixth Supplemental Indenture
dated December 10, 1996 (collectively, the "Indenture"), among the Issuer and
State Street Bank and Trust Company (the "Trustee," which term includes any
successor trustee under the Indenture with respect to the 2006 Notes), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Issuer, the Trustee and the Holders of the 2006 Notes, and of
the terms upon which the 2006 Notes are, and are to be, authenticated and
delivered. This 2006 Note is one of the series designated as the "7.125% Notes
Due December 1, 2006," limited in the aggregate principal amount to
$100,000,000.

         The 2006 Notes may be redeemed at any time at the option of the Issuer,
in whole or from time to time in part, at a redemption price (the "Redemption
Price") equal to the sum of (i) the principal amount of the 2006 Notes (or
portion thereof) being redeemed plus accrued interest thereon to the redemption
date and (ii) the Make-Whole Amount (as defined below), if any, with respect to
such 2006 Notes (or portion thereof).

         If notice has been given as provided in the Indenture and funds for the
redemption of any 2006 Notes (or any portion thereof) called for redemption
shall have been made available on the redemption date referred to in such
notice, such 2006 Notes (or any portion thereof) will cease to bear interest on
the date fixed for such redemption specified in such notice and the only right
of the Holders of the 2006 Notes will be to receive payment of the Redemption
Price, with respect to such 2006 Notes or portion thereof so redeemed.

         Notice of any optional redemption of any 2006 Notes (or any portion
thereof) will be given to Holders at their addresses, as shown in the 2006 Note
Register, not more than 60 nor less than 30 days prior to the date fixed for
redemption. The notice of redemption will specify, among other items, the
Redemption Price and the principal amount of the 2006 Notes held by such Holder
to be redeemed.

         The Issuer will notify the Trustee at least 45 days prior to giving
notice of redemption (or such shorter period as is satisfactory to the Trustee)
of the aggregate principal amount of 2006 Notes to be redeemed and their
redemption date. If less than all the 2006 Notes are to be redeemed at the
option of the Issuer, the Trustee shall select, in such manner as it shall deem
fair and appropriate, the 2006 Notes to be redeemed in whole or in part.


                                       2
<PAGE>   3

         In the event of redemption of the 2006 Notes in part only, a new 2006
Note for the amount of the unredeemed portion hereof shall be issued in the name
of the Holder hereto, upon cancellation hereof.

         As used herein:

         "Make-Whole Amount" means, in connection with any optional redemption
or accelerated payment of any 2006 Notes, the excess, if any, of (i) the
aggregate present value as of the date of such redemption or accelerated payment
of each dollar of principal being redeemed or paid and the amount of interest
(exclusive of interest accrued to the date of redemption or accelerated payment)
that would have been payable in respect of each such dollar if such redemption
or accelerated payment had not been made, determined by discounting, on a
semi-annual basis, such principal and interest at the Reinvestment Rate
(determined on the third Business Day preceding the date such notice of
redemption is given or declaration of acceleration is made) from the respective
dates on which such principal and interest would have been payable if such
redemption or accelerated payment had not been made, over (ii) the aggregate
principal amount of the 2006 Notes being redeemed or paid.

         "Reinvestment Rate" means 0.25% plus the arithmetic mean of the yields
under the respective heading "Week Ending" published in the most recent
Statistical Release under the caption "Treasury Constant Maturities" for the
maturity (rounded to the nearest month) corresponding to the remaining life to
maturity, as of the payment date of the principal being redeemed or paid. If no
maturity exactly corresponds to such maturity, yields for the two published
maturities most closely corresponding to such maturity shall be calculated
pursuant to the immediately preceding sentence and the Reinvestment Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding in each of such relevant periods to the nearest month. For the purpose
of calculating the Reinvestment Rate, the most recent Statistical Release
published prior to the date of determination of the Make-Whole Amount shall be
used.

         "Statistical Release" means the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded United
States government securities adjusted to constant maturities, or, if such
statistical release is not published at the time of any determination under the
Indenture, then such other reasonably comparable index which shall be designated
by the Issuer.

         The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Issuer on this 2006 Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Issuer, in each case, upon compliance by the Issuer with certain conditions set
forth in the Indenture, which provisions apply to this 2006 Note.

         The Issuer is subject to certain covenants contained in the Indenture
with respect to, and for the benefit of the Holders of, the 2006 Notes. The
Trustee shall not be obligated to monitor or confirm, on a continuing basis or
otherwise, the Issuer's compliance with the covenants


                                       3
<PAGE>   4

contained in the Indenture or with respect to reports or other certificates
filed under the Indenture; provided, however, that nothing herein shall relieve
the Trustee of any obligations to monitor the Issuer's timely delivery of all
reports and certificates required under Sections 703 and 1005 of the Indenture
and to fulfill its obligations under Article Six of the Indenture.

         If an Event of Default as defined in the Indenture with respect to the
2006 Notes shall occur and be continuing, the principal of the 2006 Notes may be
declared due and payable in the manner and with the effect provided in the
Indenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this 2006 Note shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
2006 Notes, the Holders of not less than a majority in principal amount of the
2006 Notes at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer
of indemnity and the Trustee shall not have received from the Holders of a
majority in principal amount of the 2006 Notes at the time Outstanding a
direction inconsistent with such request. The foregoing shall not apply to any
suit instituted by the Holder of this 2006 Note for the enforcement of any
payment of principal hereof or any interest on or after the respective due dates
expressed herein.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the 2006 Notes under the Indenture at
any time by the Issuer and the Trustee with the consent of the Holders of not
less than a majority in principal amount of the Outstanding 2006 Notes. The
Indenture also contains provisions permitting the Holders of not less than a
majority in principal amount of the 2006 Notes at the time Outstanding, on
behalf of the Holders of all 2006 Notes, to waive compliance by the Issuer with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this 2006 Note shall be conclusive and binding upon such Holder and upon all
future Holders of this 2006 Note and of any 2006 Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this 2006 Note.

         No reference herein to the Indenture and no provision of this 2006 Note
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of, and interest on, this 2006
Note at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this 2006 Note is registrable in the 2006 Note
Register, upon surrender of this 2006 Note for registration of transfer at the
office or agency of the Issuer in any Place of Payment where the principal of,
and interest on, this 2006 Note are payable, duly endorsed by, or


                                       4
<PAGE>   5

accompanied by a written instrument of transfer in form satisfactory to the
Issuer and the Security Registrar for the 2006 Notes duly executed by, the
Holder hereof or his attorney duly authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

         The 2006 Notes of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
the 2006 Notes are exchangeable for a like aggregate principal amount of 2006
Notes of this series of a different authorized denomination, as requested by the
Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this 2006 Note for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this 2006 Note is registered as the owner hereof
for all purposes, whether or not this 2006 Note be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

         All terms used in this 2006 Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE 2006 NOTES INCLUDING THIS 2006 NOTE, SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Issuer has caused "CUSIP" numbers to be
printed on the 2006 Notes as a convenience to the Holders of the 2006 Notes. No
representation is made as to the correctness or accuracy of such CUSIP numbers
as printed on the 2006 Notes, and reliance may be placed only on the other
identification numbers printed hereon.

         Unless the certificate of authentication hereon has been executed by or
on behalf of the Trustee by manual signature, this 2006 Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purposes.

                        7.875% NOTE DUE DECEMBER 1, 2016


         SPIEKER PROPERTIES, L.P., a California limited partnership (the
"Issuer"), for value received, hereby promises to pay to Cede & Co., or
registered assignee (the "Holder"), upon presentation, the principal sum of
$25,000,000 on December 1, 2016, and to pay interest on the outstanding
principal amount thereon from December 10, 1996, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on December 1 and June 1 in each year (each an
"Interest Payment Date"), commencing June 1, 1997, and at the Stated Maturity,
at the rate of 7.875% per annum, computed on the basis of a 360-day year
comprised of twelve 30-day months, until the entire principal amount hereof is
paid or duly provided for. The interest so payable, and punctually paid or duly
provided for on any Interest Payment Date will, as provided in the Indenture
(hereinafter defined), be paid to the person in whose name this Note (the "2016
Note") (or one or more predecessor 2016 Notes) is registered at the close of
business on the Regular Record Date for such Interest Payment Date which shall
be the 15th calendar day preceding the applicable Interest Payment Date. Any
such interest not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date, and may either be paid
to the Person in whose name this 2016 Note (or one or more predecessor 2016
Notes) is registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest to be fixed by the Trustee, notice whereof
shall be given to Holders of 2016 Notes not more than 15 days and not less than
10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the 2016 Notes may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Payments
of the principal of, and interest on, this 2016 Note will be made at the office
or agency of the Trustee (hereinafter defined) maintained for that purpose at

Two International Place, Boston, Massachusetts 02110, or elsewhere as provided
in the Indenture, in United States Dollars; provided, however, that at the
option of the Holder hereof, and upon written notice to the Trustee of not less
than five Business Days prior to the applicable Interest Payment Date, payment
of interest may be made by (i) check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register kept for
the 2016 Notes pursuant to Section 305 of the Indenture (the "2016 Note
Register") or (ii) transfer to an account of the Person entitled thereto located
inside the United States.

         This 2016 Note is one of a fully authorized issue of securities of the
Issuer issued as a series of securities issued and to be issued under an
Indenture, dated as of December 6, 1995 and the Seventh Supplemental Indenture
dated December 10, 1996 (collectively, the "Indenture"), among the Issuer and
State Street Bank and Trust Company (the "Trustee," which term includes any
successor trustee under the Indenture with respect to the 2016 Notes), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Issuer, the Trustee and the Holders of the 2016 Notes, and of
the terms upon which the 2016 Notes are, and are to be, authenticated and
delivered. This 2016 Note is one of the series designated as the "7.875% Notes
Due December 1, 2016," limited in the aggregate principal amount to $25,000,000.

         The 2016 Notes may be redeemed at any time at the option of the Issuer,
in whole or from time to time in part, at a redemption price (the "Redemption
Price") equal to the sum of (i) the principal amount of the 2016 Notes (or
portion thereof) being redeemed plus accrued interest thereon to the redemption
date and (ii) the Make-Whole Amount (as defined below), if any, with respect to
such 2016 Notes (or portion thereof).

         If notice has been given as provided in the Indenture and funds for the
redemption of any 2016 Notes (or any portion thereof) called for redemption
shall have been made available on the redemption date referred to in such
notice, such 2016 Notes (or any portion thereof) will cease to bear interest on
the date fixed for such redemption specified in such notice and the only right
of the Holders of the 2016 Notes will be to receive payment of the Redemption
Price, with respect to such 2016 Notes or portion thereof so redeemed.

         Notice of any optional redemption of any 2016 Notes (or any portion
thereof) will be given to Holders at their addresses, as shown in the 2016 Note
Register, not more than 60 nor less than 30 days prior to the date fixed for
redemption. The notice of redemption will specify, among other items, the
Redemption Price and the principal amount of the 2016 Notes held by such Holder
to be redeemed.

         The Issuer will notify the Trustee at least 45 days prior to giving
notice of redemption (or such shorter period as is satisfactory to the Trustee)
of the aggregate principal amount of 2016 Notes to be redeemed and their
redemption date. If less than all the 2016 Notes are to be redeemed at the
option of the Issuer, the Trustee shall select, in such manner as it shall deem
fair and appropriate, the 2016 Notes to be redeemed in whole or in part.


                                       2
<PAGE>   3

         In the event of redemption of the 2016 Notes in part only, a new 2016
Note for the amount of the unredeemed portion hereof shall be issued in the name
of the Holder hereto, upon cancellation hereof.

         As used herein:

         "Make-Whole Amount" means, in connection with any optional redemption
or accelerated payment of any 2016 Notes, the excess, if any, of (i) the
aggregate present value as of the date of such redemption or accelerated payment
of each dollar of principal being redeemed or paid and the amount of interest
(exclusive of interest accrued to the date of redemption or accelerated payment)
that would have been payable in respect of each such dollar if such redemption
or accelerated payment had not been made, determined by discounting, on a
semi-annual basis, such principal and interest at the Reinvestment Rate
(determined on the third Business Day preceding the date such notice of
redemption is given or declaration of acceleration is made) from the respective
dates on which such principal and interest would have been payable if such
redemption or accelerated payment had not been made, over (ii) the aggregate
principal amount of the 2016 Notes being redeemed or paid.

         "Reinvestment Rate" means 0.25% plus the arithmetic mean of the yields
under the respective heading "Week Ending" published in the most recent
Statistical Release under the caption "Treasury Constant Maturities" for the
maturity (rounded to the nearest month) corresponding to the remaining life to
maturity, as of the payment date of the principal being redeemed or paid. If no
maturity exactly corresponds to such maturity, yields for the two published
maturities most closely corresponding to such maturity shall be calculated
pursuant to the immediately preceding sentence and the Reinvestment Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding in each of such relevant periods to the nearest month. For the purpose
of calculating the Reinvestment Rate, the most recent Statistical Release
published prior to the date of determination of the Make-Whole Amount shall be
used.

         "Statistical Release" means the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded United
States government securities adjusted to constant maturities, or, if such
statistical release is not published at the time of any determination under the
Indenture, then such other reasonably comparable index which shall be designated
by the Issuer.

         The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Issuer on this 2016 Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Issuer, in each case, upon compliance by the Issuer with certain conditions set
forth in the Indenture, which provisions apply to this 2016 Note.

         The Issuer is subject to certain covenants contained in the Indenture
with respect to, and for the benefit of the Holders of, the 2016 Notes. The
Trustee shall not be obligated to monitor or confirm, on a continuing basis or
otherwise, the Issuer's compliance with the covenants


                                       3
<PAGE>   4

contained in the Indenture or with respect to reports or other certificates
filed under the Indenture; provided, however, that nothing herein shall relieve
the Trustee of any obligations to monitor the Issuer's timely delivery of all
reports and certificates required under Sections 703 and 1005 of the Indenture
and to fulfill its obligations under Article Six of the Indenture.

         If an Event of Default as defined in the Indenture with respect to the
2016 Notes shall occur and be continuing, the principal of the 2016 Notes may be
declared due and payable in the manner and with the effect provided in the
Indenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this 2016 Note shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
2016 Notes, the Holders of not less than a majority in principal amount of the
2016 Notes at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer
of indemnity and the Trustee shall not have received from the Holders of a
majority in principal amount of the 2016 Notes at the time Outstanding a
direction inconsistent with such request. The foregoing shall not apply to any
suit instituted by the Holder of this 2016 Note for the enforcement of any
payment of principal hereof or any interest on or after the respective due dates
expressed herein.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the 2016 Notes under the Indenture at
any time by the Issuer and the Trustee with the consent of the Holders of not
less than a majority in principal amount of the Outstanding 2016 Notes. The
Indenture also contains provisions permitting the Holders of not less than a
majority in principal amount of the 2016 Notes at the time Outstanding, on
behalf of the Holders of all 2016 Notes, to waive compliance by the Issuer with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this 2016 Note shall be conclusive and binding upon such Holder and upon all
future Holders of this 2016 Note and of any 2016 Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this 2016 Note.

         No reference herein to the Indenture and no provision of this 2016 Note
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of, and interest on, this 2016
Note at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this 2016 Note is registrable in the 2016 Note
Register, upon surrender of this 2016 Note for registration of transfer at the
office or agency of the Issuer in any Place of Payment where the principal of,
and interest on, this 2016 Note are payable, duly endorsed by, or


                                       4
<PAGE>   5

accompanied by a written instrument of transfer in form satisfactory to the
Issuer and the Security Registrar for the 2016 Notes duly executed by, the
Holder hereof or his attorney duly authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

         The 2016 Notes of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
the 2016 Notes are exchangeable for a like aggregate principal amount of 2016
Notes of this series of a different authorized denomination, as requested by the
Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this 2016 Note for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this 2016 Note is registered as the owner hereof
for all purposes, whether or not this 2016 Note be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

         All terms used in this 2016 Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE 2016 NOTES INCLUDING THIS 2016 NOTE, SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Issuer has caused "CUSIP" numbers to be
printed on the 2016 Notes as a convenience to the Holders of the 2016 Notes. No
representation is made as to the correctness or accuracy of such CUSIP numbers
as printed on the 2016 Notes, and reliance may be placed only on the other
identification numbers printed hereon.

         Unless the certificate of authentication hereon has been executed by or
on behalf of the Trustee by manual signature, this 2016 Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purposes.

             funds for the redemption of any 2006 Notes (or any portion thereof)
             called for redemption shall have been made available on the
             redemption date referred to in such notice, such 2006 Notes (or any

             Trustee of the Redemption Price and the Trustee may rely and shall
             be fully protected in acting upon the determination of the Company
             as to such Price.

             satisfactory to the Trustee) of the aggregate principal amount of
             2006 Notes to be redeemed and their redemption date. If less than
             all the 2006 Notes are to be redeemed at the option of the Issuer,
             the Trustee shall select, in such manner as it shall deem fair and
             appropriate, the 2006 Notes to be redeemed in whole or in part.

             only, a new 2006 Note for the amount of the unredeemed portion
             thereof shall be issued in the name of the Holder thereto, upon
             cancellation thereof.

                  redemption or accelerated payment of any 2006 Notes, the
                  excess, if any, of (i) the aggregate present value as of the
                  date of such redemption or accelerated payment of each dollar
                  of principal being redeemed or paid and the amount of interest
                  (exclusive of interest accrued to the date of redemption or
                  accelerated payment) that would have been payable in respect
                  of each such dollar if such redemption or accelerated payment
                  had not been made, determined by discounting, on a semi-annual
                  basis, such principal and interest at the Reinvestment Rate
                  (determined on the third Business Day preceding the date such
                  notice of redemption is given or declaration of acceleration
                  is made) from the respective dates on which such principal and
                  interest would have been payable if such redemption or
                  accelerated payment had not been made, over (ii) the aggregate
                  principal amount of the 2006 Notes being redeemed or paid.

                      "Reinvestment Rate" means 0.25% plus the arithmetic mean
                  of the yields under the respective heading "Week Ending"
                  published in the most recent Statistical Release under the
                  caption "Treasury Constant Maturities" for the maturity
                  (rounded to the nearest month) corresponding to the remaining
                  life to maturity, as of the payment date of the principal
                  being redeemed or paid. If no maturity exactly corresponds to
                  such maturity, yields for the two published maturities most
                  closely corresponding to such maturity shall be calculated
                  pursuant to the immediately preceding sentence and the
                  Reinvestment Rate shall be interpolated or extrapolated from
                  such yields on a straight-line basis, rounding in each of such
                  relevant periods to the nearest month. For the purpose of
                  calculating the Reinvestment Rate, the most recent Statistical
                  Release published prior to the date of determination of the
                  Make-Whole Amount shall be used.

                      "Statistical Release" means the statistical release
                  designated "H.15(519)" or any successor publication which is
                  published weekly by the Federal Reserve System and which
                  establishes yields on actively traded United States government
                  securities adjusted to constant maturities, or, if such
                  statistical release is not published at the time of any
                  determination under the Indenture, then such other reasonably
                  comparable index which shall be designated by the Issuer.

                  (7)      The 2006 Notes shall not be redeemable at the option
         of any Holder thereof, upon the occurrence of any particular
         circumstances or otherwise. The 2006 Notes will not have the benefit of
         any sinking fund.

                  (8)      The 2006 Notes shall be issuable in denominations of
         $1,000 and any integral multiple thereof.

                  (9)      The Trustee shall also be the Security Registrar and
         Paying Agent.

                  (10)     The entire outstanding principal amount plus the
         Make-Whole Amount of the 2006 Notes shall be payable upon declaration
         of acceleration of the maturity thereof pursuant to Section 502 of the
         Indenture.

                  (11)     Payments of the principal of and interest on the 2006
         Notes shall be made in U.S. Dollars, and the 2006 Notes shall be
         denominated in U.S. Dollars.

                  (12)     The 2006 Notes will be payable on the Stated Maturity
         Date in an amount equal to the principal amount thereof plus any unpaid
         interest accrued to the Stated Maturity Date.

                  (13)     The Holders of the 2006 Notes shall have no special
         rights in addition to those provided in the Indenture upon the
         occurrence of any particular events.

                  (14)     (A) There shall be no deletions from, modifications
         of or additions to the Events of Default with respect to the 2006 Notes
         set forth in the Indenture.

                           (B) There shall be the following additions to the
         covenants set forth in the Indenture with respect to the 2006 Notes,
         which shall be effective only for so long as any of the 2006 Notes are
         Outstanding:

                               Limitations On Incurrence of Debt. The Issuer
                  will not, and will not permit any Subsidiary to, incur any
                  Debt (as defined below), other than inter-company debt
                  representing Debt to which the only parties are Spieker
                  Properties, Inc., a Maryland corporation (the "General
                  Partner"), the Issuer and any of their Subsidiaries (but only
                  so long as such Debt is held solely by any of the General
                  Partner, the Issuer and any Subsidiary) that is subordinate in
                  right of payment to the 2006 Notes if, immediately after
                  giving effect to the incurrence of such additional Debt, the
                  aggregate principal amount of all outstanding Debt of the
                  Issuer and its Subsidiaries on a consolidated basis is greater
                  than 60% of the sum of (i) Total Assets (as defined below) as
                  of the end of the calendar quarter covered in the Issuer's
                  Annual Report on Form 10-K or Quarterly Report on Form 10-Q,
                  as the case may be, most recently filed with the Trustee (or
                  such reports of the General Partner if filed by the Issuer
                  with the Trustee in lieu of filing its own reports) prior to
                  the incurrence of such additional Debt and (ii) the increase
                  in Total Assets from the end of such quarter including,
                  without limitation, any increase in Total Assets resulting
                  from the incurrence of such additional Debt (such increase,
                  together with the Total Assets, is referred to as "Adjusted
                  Total Assets").

                               In addition to the foregoing limitation on the
                  incurrence of Debt, the Issuer will not, and will not permit
                  any Subsidiary to, incur any Debt if the ratio of Consolidated
                  Income Available for Debt Service to the Annual Service Charge
                  (in each case as defined below) for the four consecutive
                  fiscal quarters most recently ended prior to the date on which
                  such additional Debt is to be incurred shall have been less
                  than 1.5 to 1, on a pro forma basis after giving effect to the
                  incurrence of such Debt and to the application of the proceeds
                  therefrom, and calculated on the assumption that (i) such Debt
                  and any other Debt incurred


                                       4
<PAGE>   5

                  by the Issuer or its Subsidiaries since the first day of such
                  four-quarter period and the application of the proceeds
                  therefrom, including to refinance other Debt, had occurred at
                  the beginning of such period, (ii) the repayment or retirement
                  of any other Debt by the Issuer or its Subsidiaries since the
                  first day of such four-quarter period had been incurred,
                  repaid or retired at the beginning of such period (except
                  that, in making such computation, the amount of Debt under any
                  revolving credit facility shall be computed based upon the
                  average daily balance of such Debt during such period), (iii)
                  the income earned on any increase in Adjusted Total Assets
                  since the end of such four-quarter period had been earned, on
                  an annualized basis, during such period, and (iv) in the case
                  of any acquisition or disposition by the Issuer or any
                  Subsidiary of any asset or group of assets since the first day
                  of such four-quarter period, including, without limitation, by
                  merger, stock purchase or sale, or asset purchase or sale,
                  such acquisition or disposition or any related repayment of
                  Debt had occurred as of the first day of such period with the
                  appropriate adjustments with respect to such acquisition or
                  disposition being included in such pro forma calculation.

                               In addition to the foregoing limitations on the
                  incurrence of Debt, the Issuer will not, and will not permit
                  any Subsidiary to, incur any Debt secured by any mortgage,
                  lien, charge, pledge, encumbrance or security interest of any
                  kind upon any of the property of the Issuer or any Subsidiary
                  ("Secured Debt"), whether owned at the date of the Indenture
                  or thereafter acquired, if, immediately after giving effect to
                  the incurrence of such additional Secured Debt, the aggregate
                  principal amount of all outstanding Secured Debt is greater
                  than 40% of Adjusted Total Assets.

                               For purposes of the foregoing provisions
                  regarding the limitation on the incurrence of Debt, Debt shall
                  be deemed to be "incurred" by the Issuer or a Subsidiary
                  whenever the Issuer and its Subsidiary shall create, assume,
                  guarantee or otherwise become liable in respect thereof.
                  Maintenance of Total Unencumbered Assets. The Issuer is
                  required to maintain Total Unencumbered Assets of not less
                  than 165% of the aggregate outstanding principal amount of all
                  outstanding Unsecured Debt.

                               As used herein:

                               "Annual Service Charge" as of any date means the
                  amount which is expensed in any 12-month period for interest
                  on Debt of the Issuer and its Subsidiaries.

                               "Consolidated Income Available For Debt Service"
                  for any period means Consolidated Net Income plus amounts
                  which have been deducted for (a) interest on Debt of the
                  Issuer and its Subsidiaries, (b) provision for taxes of the
                  Issuer and its Subsidiaries based on income, (c) amortization
                  of Debt discount, (d) provisions for gains and losses on
                  properties, (e) depreciation and amortization, (f) the effect
                  of any noncash charge resulting from a change in 


                                        5
<PAGE>   6

                  accounting principles in determining Consolidated Net Income
                  for such period and (g) amortization of deferred charges.

                               "Consolidated Net Income" for any period means
                  the amount of consolidated net income (or loss) of the Issuer
                  and its Subsidiaries for such period determined on a
                  consolidated basis in accordance with generally accepted
                  accounting principles.

                               "Debt" of the Issuer or any Subsidiary means any
                  indebtedness of the Issuer or such Subsidiary, as applicable,
                  whether or not contingent, in respect of (i) borrowed money
                  evidenced by bonds, notes, debentures or similar instruments,
                  (ii) indebtedness secured by any mortgage, pledge, lien,
                  charge, encumbrance or any security interest existing on
                  property owned by the Issuer or such Subsidiary, (iii) the
                  reimbursement obligations, contingent or otherwise, in
                  connection with any letters of credit actually issued or
                  amounts representing the balance that constitutes an accrued
                  expense or trade payable or (iv) any lease of property by the
                  Issuer or such Subsidiary as lessee which is reflected in the
                  Issuer's consolidated balance sheet as a capitalized lease in
                  accordance with generally accepted accounting principles, in
                  the case of items of indebtedness under (i) through (iii)
                  above to the extent that any such items (other than letters of
                  credit) would appear as a liability on the Issuer's
                  consolidated balance sheet in accordance with generally
                  accepted accounting principles, and also includes, to the
                  extent not otherwise included, any obligation by the Issuer or
                  such Subsidiary to be liable for, or to pay, as obligor,
                  guarantor or otherwise (other than for purposes of collection
                  in the ordinary course of business), indebtedness of another
                  person (other than the Issuer or any Subsidiary).

                               "Subsidiary" means a corporation, partnership or
                  limited liability company, a majority of the outstanding
                  voting stock, partnership interests or membership interests,
                  as the case may be, of which is owned or controlled, directly
                  or indirectly, by the Issuer or by one or more other
                  Subsidiaries of the Issuer. For the purposes of this
                  definition, "voting stock" means stock having the voting power
                  for the election of directors, general partners, managers or
                  trustees, as the case may be, whether at all times or only so
                  long as no senior class of stock has such voting power by
                  reason of any contingency.

                               "Total Assets" as of any date means the sum of
                  (i) Undepreciated Real Estate Assets and (ii) all other assets
                  of the Issuer and its Subsidiaries on a consolidated basis
                  determined in accordance with generally accepted accounting
                  principles (but excluding intangibles and accounts
                  receivable).

                               "Total Unencumbered Assets" as of any date means
                  the sum of (i) those Undepreciated Real Estate Assets which
                  have not been pledged, mortgaged or otherwise encumbered by
                  the owner thereof to secure Debt, excluding infrastructure
                  assessment bonds, and (ii) all other assets of the Issuer and
                  its Subsidiaries determined in accordance with generally
                  accepted accounting principles (but excluding intangibles and
                  accounts receivable) which have not


                                       6
<PAGE>   7

                  been pledged, mortgaged or otherwise encumbered by the owner
                  thereof to secure Debt.

                  means the cost (original cost plus capital improvements) of
                  real estate assets of the Issuer and its Subsidiaries on such
                  date, before depreciation and amortization, determined on a
                  consolidated basis in accordance with generally accepted
                  accounting principles.

                               "Unsecured Debt" as of any date means Debt which
                  is not secured by any mortgage, lien, charge, pledge,
                  encumbrance or security interest of any kind upon any of the
                  properties of the Issuer or any Subsidiary.

                           (C) The Trustee shall not be obligated to monitor or
         confirm, on a continuing basis or otherwise, the Issuer's compliance
         with the covenants contained in this subsection or with respect to
         reports or other documents filed under the Indenture; provided,
         however, that nothing herein shall relieve the Trustee of any
         obligations to monitor the Issuer's timely delivery of all reports and
         certificates required under Sections 703 and 1005 of the Indenture and
         to fulfill its obligations under Article Six of the Indenture.

         Indenture. DTC shall be the depository with respect to the permanent
         global 2006 Note.

                  (16)     The 2006 Notes shall not be issuable as Bearer
         Securities.

                  (17)     Interest on any 2006 Note shall be payable only to
         the Person in whose name that 2006 Note (or one or more predecessor
         2006 Notes thereof) is registered at the close of business on the
         Regular Record Date for such interest.

                  (18)     Sections 1402 and 1403 of the Indenture shall be
         applicable to the 2006 Notes.

                  (19)     The 2006 Notes shall not be issuable in definitive
         form except under the circumstances described in Section 305 of the
         Indenture.

                  (20)     Articles Sixteen and Seventeen of the Indenture shall

                        7.125% NOTE DUE DECEMBER 1, 2006


         SPIEKER PROPERTIES, L.P., a California limited partnership (the
"Issuer"), for value received, hereby promises to pay to Cede & Co., or
registered assignee (the "Holder"), upon presentation, the principal sum of
$100,000,000 on December 1, 2006, and to pay interest on the outstanding
principal amount thereon from December 10, 1996, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on December 1 and June 1 in each year (each an
"Interest Payment Date"), commencing June 1, 1997, and at the Stated Maturity,
at the rate of 7.125% per annum, computed on the basis of a 360-day year
comprised of twelve 30-day months, until the entire principal amount hereof is
paid or duly provided for. The interest so payable, and punctually paid or duly
provided for on any Interest Payment Date will, as provided in the Indenture
(hereinafter defined), be paid to the person in whose name this Note (the "2006
Note") (or one or more predecessor 2006 Notes) is registered at the close of
business on the Regular Record Date for such Interest Payment Date which shall
be the 15th calendar day preceding the applicable Interest Payment Date. Any
such interest not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date, and may either be paid
to the Person in whose name this 2006 Note (or one or more predecessor 2006
Notes) is registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest to be fixed by the Trustee, notice whereof
shall be given to Holders of 2006 Notes not more than 15 days and not less than
10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the 2006 Notes may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Payments
of the principal of, and interest on, this 2006 Note will be made at the office
or agency of the Trustee (hereinafter defined) maintained for that purpose at


                                       1
<PAGE>   12

Two International Place, Boston, Massachusetts 02110, or elsewhere as provided
in the Indenture, in United States Dollars; provided, however, that at the
option of the Holder hereof, and upon written notice to the Trustee of not less
than five Business Days prior to the applicable Interest Payment Date, payment
of interest may be made by (i) check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register kept for
the 2006 Notes pursuant to Section 305 of the Indenture (the "2006 Note
Register") or (ii) transfer to an account of the Person entitled thereto located
inside the United States.

         This 2006 Note is one of a fully authorized issue of securities of the
Issuer issued as a series of securities issued and to be issued under an
Indenture, dated as of December 6, 1995 and the Sixth Supplemental Indenture
dated December 10, 1996 (collectively, the "Indenture"), among the Issuer and
State Street Bank and Trust Company (the "Trustee," which term includes any
successor trustee under the Indenture with respect to the 2006 Notes), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Issuer, the Trustee and the Holders of the 2006 Notes, and of
the terms upon which the 2006 Notes are, and are to be, authenticated and
delivered. This 2006 Note is one of the series designated as the "7.125% Notes
Due December 1, 2006," limited in the aggregate principal amount to
$100,000,000.

         The 2006 Notes may be redeemed at any time at the option of the Issuer,
in whole or from time to time in part, at a redemption price (the "Redemption
Price") equal to the sum of (i) the principal amount of the 2006 Notes (or
portion thereof) being redeemed plus accrued interest thereon to the redemption
date and (ii) the Make-Whole Amount (as defined below), if any, with respect to
such 2006 Notes (or portion thereof).

         If notice has been given as provided in the Indenture and funds for the
redemption of any 2006 Notes (or any portion thereof) called for redemption
shall have been made available on the redemption date referred to in such
notice, such 2006 Notes (or any portion thereof) will cease to bear interest on
the date fixed for such redemption specified in such notice and the only right
of the Holders of the 2006 Notes will be to receive payment of the Redemption
Price, with respect to such 2006 Notes or portion thereof so redeemed.

         Notice of any optional redemption of any 2006 Notes (or any portion
thereof) will be given to Holders at their addresses, as shown in the 2006 Note
Register, not more than 60 nor less than 30 days prior to the date fixed for
redemption. The notice of redemption will specify, among other items, the
Redemption Price and the principal amount of the 2006 Notes held by such Holder
to be redeemed.

         The Issuer will notify the Trustee at least 45 days prior to giving
notice of redemption (or such shorter period as is satisfactory to the Trustee)
of the aggregate principal amount of 2006 Notes to be redeemed and their
redemption date. If less than all the 2006 Notes are to be redeemed at the
option of the Issuer, the Trustee shall select, in such manner as it shall deem
fair and appropriate, the 2006 Notes to be redeemed in whole or in part.


                                       2
<PAGE>   13

         In the event of redemption of the 2006 Notes in part only, a new 2006
Note for the amount of the unredeemed portion hereof shall be issued in the name
of the Holder hereto, upon cancellation hereof.

         As used herein:

         "Make-Whole Amount" means, in connection with any optional redemption
or accelerated payment of any 2006 Notes, the excess, if any, of (i) the
aggregate present value as of the date of such redemption or accelerated payment
of each dollar of principal being redeemed or paid and the amount of interest
(exclusive of interest accrued to the date of redemption or accelerated payment)
that would have been payable in respect of each such dollar if such redemption
or accelerated payment had not been made, determined by discounting, on a
semi-annual basis, such principal and interest at the Reinvestment Rate
(determined on the third Business Day preceding the date such notice of
redemption is given or declaration of acceleration is made) from the respective
dates on which such principal and interest would have been payable if such
redemption or accelerated payment had not been made, over (ii) the aggregate
principal amount of the 2006 Notes being redeemed or paid.

         "Reinvestment Rate" means 0.25% plus the arithmetic mean of the yields
under the respective heading "Week Ending" published in the most recent
Statistical Release under the caption "Treasury Constant Maturities" for the
maturity (rounded to the nearest month) corresponding to the remaining life to
maturity, as of the payment date of the principal being redeemed or paid. If no
maturity exactly corresponds to such maturity, yields for the two published
maturities most closely corresponding to such maturity shall be calculated
pursuant to the immediately preceding sentence and the Reinvestment Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding in each of such relevant periods to the nearest month. For the purpose
of calculating the Reinvestment Rate, the most recent Statistical Release
published prior to the date of determination of the Make-Whole Amount shall be
used.

         "Statistical Release" means the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded United
States government securities adjusted to constant maturities, or, if such
statistical release is not published at the time of any determination under the
Indenture, then such other reasonably comparable index which shall be designated
by the Issuer.

         The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Issuer on this 2006 Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Issuer, in each case, upon compliance by the Issuer with certain conditions set
forth in the Indenture, which provisions apply to this 2006 Note.

         The Issuer is subject to certain covenants contained in the Indenture
with respect to, and for the benefit of the Holders of, the 2006 Notes. The
Trustee shall not be obligated to monitor or confirm, on a continuing basis or
otherwise, the Issuer's compliance with the covenants


                                       3
<PAGE>   14

contained in the Indenture or with respect to reports or other certificates
filed under the Indenture; provided, however, that nothing herein shall relieve
the Trustee of any obligations to monitor the Issuer's timely delivery of all
reports and certificates required under Sections 703 and 1005 of the Indenture
and to fulfill its obligations under Article Six of the Indenture.

         If an Event of Default as defined in the Indenture with respect to the
2006 Notes shall occur and be continuing, the principal of the 2006 Notes may be
declared due and payable in the manner and with the effect provided in the
Indenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this 2006 Note shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
2006 Notes, the Holders of not less than a majority in principal amount of the
2006 Notes at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer
of indemnity and the Trustee shall not have received from the Holders of a
majority in principal amount of the 2006 Notes at the time Outstanding a
direction inconsistent with such request. The foregoing shall not apply to any
suit instituted by the Holder of this 2006 Note for the enforcement of any
payment of principal hereof or any interest on or after the respective due dates
expressed herein.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the 2006 Notes under the Indenture at
any time by the Issuer and the Trustee with the consent of the Holders of not
less than a majority in principal amount of the Outstanding 2006 Notes. The
Indenture also contains provisions permitting the Holders of not less than a
majority in principal amount of the 2006 Notes at the time Outstanding, on
behalf of the Holders of all 2006 Notes, to waive compliance by the Issuer with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this 2006 Note shall be conclusive and binding upon such Holder and upon all
future Holders of this 2006 Note and of any 2006 Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this 2006 Note.

         No reference herein to the Indenture and no provision of this 2006 Note
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of, and interest on, this 2006
Note at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this 2006 Note is registrable in the 2006 Note
Register, upon surrender of this 2006 Note for registration of transfer at the
office or agency of the Issuer in any Place of Payment where the principal of,
and interest on, this 2006 Note are payable, duly endorsed by, or


                                       4
<PAGE>   15

accompanied by a written instrument of transfer in form satisfactory to the
Issuer and the Security Registrar for the 2006 Notes duly executed by, the
Holder hereof or his attorney duly authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees.

         The 2006 Notes of this series are issuable only in registered form
without coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to certain limitations therein set forth,
the 2006 Notes are exchangeable for a like aggregate principal amount of 2006
Notes of this series of a different authorized denomination, as requested by the
Holder surrendering the same.

         No service charge shall be made for any such registration of transfer
or exchange, but the Issuer may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         Prior to due presentment of this 2006 Note for registration of
transfer, the Issuer, the Trustee and any agent of the Issuer or the Trustee may
treat the Person in whose name this 2006 Note is registered as the owner hereof
for all purposes, whether or not this 2006 Note be overdue, and neither the
Issuer, the Trustee nor any such agent shall be affected by notice to the
contrary.

         All terms used in this 2006 Note which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

         THE INDENTURE AND THE 2006 NOTES INCLUDING THIS 2006 NOTE, SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK.

         Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Issuer has caused "CUSIP" numbers to be
printed on the 2006 Notes as a convenience to the Holders of the 2006 Notes. No
representation is made as to the correctness or accuracy of such CUSIP numbers
as printed on the 2006 Notes, and reliance may be placed only on the other
identification numbers printed hereon.

         Unless the certificate of authentication hereon has been executed by or
on behalf of the Trustee by manual signature, this 2006 Note shall not be
entitled to any benefit under the Indenture or be valid or obligatory for any
purposes.

                  (2)      The aggregate principal amount of the 2016 Notes that
         may be authenticated and delivered under the Indenture (except for 2016
         Notes authenticated and delivered upon registration of transfer of, or
         in exchange for, or in lieu of, other 2016 Notes pursuant to Sections
         304, 305, 306, 906, 1107 or 1305 of the Indenture) shall be up to
         $25,000,000.

                  (3)      The entire outstanding principal of the 2016 Notes
         shall be payable on December 1, 2016 (the "Stated Maturity Date").

                  (4)      The rate at which the 2016 Notes shall bear interest
         shall be 7.875%; the date from which interest shall accrue shall be
         December 10, 1996; the Interest Payment Dates for the 2016 Notes on
         which interest will be payable shall be December 1 and June 1 in each
         year, beginning June 1, 1997; the Regular Record Dates for the interest
         payable on the 2016 Notes on any Interest Payment Date shall be the

         Date; and the basis upon which interest shall be calculated shall be
         that of a 360-day year consisting of twelve 30-day months.

                  (5)      The place where the principal of and interest on the
         2016 Notes shall be payable and 2016 Notes may be surrendered for the
         registration of transfer or exchange shall be the Corporate Trust
         Office of the Trustee which, as of this writing, is located at Two
         International Place, Boston, Massachusetts 02110. The place where
         notices or demands to or upon the Issuer in respect of the 2016 Notes
         and the Indenture may be served shall be the Corporate Trust Office of
         the Trustee.

                  (6)      (A) The 2016 Notes may be redeemed at any time at the
         option of the Issuer, in whole or from time to time in part, at a
         redemption price equal to the sum of (i) the principal amount of the
         2016 Notes (or portion thereof) being redeemed plus accrued interest
         thereon to the redemption date and (ii) the Make-Whole Amount (as
         defined below), if any, with respect to such 2016 Notes (or portion
         thereof) (the "Redemption Price").


                       If notice has been given as provided in the Indenture and
                  funds for the redemption of any 2016 Notes (or any portion
                  thereof) called for redemption shall have been made available
                  on the redemption date referred to in such notice, such 2016
                  Notes (or any portion thereof) will cease to bear interest on
                  the date fixed for such redemption specified in such notice
                  and the only right of the Holders of the 2016 Notes will be to
                  receive payment of the Redemption Price, with respect to such
                  2016 Notes or portion thereof so redeemed.

                       Notice of any optional redemption of any 2016 Notes (or
                  any portion thereof) will be given to Holders at their
                  addresses, as shown in the security register for the 2016
                  Notes, not more than 60 nor less than 30 days prior to the
                  date fixed for redemption. The notice of redemption will
                  specify, among other items, the Redemption Price and the
                  principal amount of the 2016 Notes held by such Holder to be
                  redeemed. On the third Business Day preceding the date notice
                  of redemption is given, the Company will notify the Trustee of
                  the Redemption Price and the Trustee may rely and shall be
                  fully protected in acting upon the determination of the
                  Company as to such Price.

                       The Issuer will notify the Trustee at least 45 days prior
                  to giving notice of redemption (or such shorter period as is
                  satisfactory to the Trustee) of the aggregate principal amount
                  of 2016 Notes to be redeemed and their redemption date. If
                  less than all the 2016 Notes are to be redeemed at the option
                  of the Issuer, the Trustee shall select, in such manner as it
                  shall deem fair and appropriate, the 2016 Notes to be redeemed
                  in whole or in part.

                       In the event of redemption of the 2016 Notes in part
                  only, a new 2016 Note for the amount of the unredeemed portion
                  thereof shall be issued in the name of the Holder thereto,
                  upon cancellation thereof.

                       (B) As used herein:

                       "Make-Whole Amount" means, in connection with any
                  optional redemption or accelerated payment of any 2016 Notes,
                  the excess, if any, of (i) the aggregate present value as of
                  the date of such redemption or accelerated payment of each
                  dollar of principal being redeemed or paid and the amount of
                  interest (exclusive of interest accrued to the date of
                  redemption or accelerated payment) that would have been
                  payable in respect of each such dollar if such redemption or
                  accelerated payment had not been made, determined by
                  discounting, on a semi-annual basis, such principal and
                  interest at the Reinvestment Rate (determined on the third
                  Business Day preceding the date such notice of redemption is
                  given or declaration of acceleration is made) from the
                  respective dates on which such principal and interest would
                  have been payable if such redemption or accelerated payment
                  had not been made, over (ii) the aggregate principal amount of
                  the 2016 Notes being redeemed or paid.

                       "Reinvestment Rate" means 0.25% plus the arithmetic mean
                  of the yields under the respective heading "Week Ending"
                  published in the most recent Statistical Release under the
                  caption "Treasury Constant Maturities" for the maturity
                  (rounded to the nearest month) corresponding to the remaining
                  life to maturity, as of the payment date of the principal
                  being redeemed or paid. If no maturity exactly corresponds to
                  such maturity, yields for the two published maturities most
                  closely corresponding to such maturity shall be calculated
                  pursuant to the immediately preceding sentence and the
                  Reinvestment Rate shall be interpolated or extrapolated from
                  such yields on a straight-line basis, rounding in each of such
                  relevant periods to the nearest month. For the purpose of
                  calculating the Reinvestment Rate, the most recent Statistical
                  Release published prior to the date of determination of the
                  Make-Whole Amount shall be used.

                       "Statistical Release" means the statistical release
                  designated "H.15(519)" or any successor publication which is
                  published weekly by the Federal Reserve System and which
                  establishes yields on actively traded United States government
                  securities adjusted to constant maturities, or, if such
                  statistical release is not published at the time of any
                  determination under the Indenture, then such other reasonably
                  comparable index which shall be designated by the Issuer.

                  (7)      The 2016 Notes shall not be redeemable at the option
         of any Holder thereof, upon the occurrence of any particular
         circumstances or otherwise. The 2016 Notes will not have the benefit of
         any sinking fund.

                  (8)      The 2016 Notes shall be issuable in denominations of
         $1,000 and any integral multiple thereof.

                  (9)      The Trustee shall also be the Security Registrar and
         Paying Agent.

<PAGE>   4

                  (10)     The entire outstanding principal amount plus the
         Make-Whole Amount of the 2016 Notes shall be payable upon declaration
         of acceleration of the maturity thereof pursuant to Section 502 of the
         Indenture.

                  (11)     Payments of the principal of and interest on the 2016
         Notes shall be made in U.S. Dollars, and the 2016 Notes shall be
         denominated in U.S. Dollars.

                  (12)     The 2016 Notes will be payable on the Stated Maturity
         Date in an amount equal to the principal amount thereof plus any unpaid
         interest accrued to the Stated Maturity Date.

                  (13)     The Holders of the 2016 Notes shall have no special
         rights in addition to those provided in the Indenture upon the
         occurrence of any particular events.

                  (14)     (A) There shall be no deletions from, modifications
         of or additions to the Events of Default with respect to the 2016 Notes
         set forth in the Indenture.

                           (B) There shall be the following additions to the
         covenants set forth in the Indenture with respect to the 2016 Notes,
         which shall be effective only for so long as any of the 2016 Notes are
         Outstanding:

                               Limitations On Incurrence of Debt. The Issuer
                  will not, and will not permit any Subsidiary to, incur any
                  Debt (as defined below), other than inter-company debt
                  representing Debt to which the only parties are Spieker
                  Properties, Inc., a Maryland corporation (the "General
                  Partner"), the Issuer and any of their Subsidiaries (but only
                  so long as such Debt is held solely by any of the General
                  Partner, the Issuer and any Subsidiary) that is subordinate in
                  right of payment to the 2016 Notes if, immediately after
                  giving effect to the incurrence of such additional Debt, the
                  aggregate principal amount of all outstanding Debt of the
                  Issuer and its Subsidiaries on a consolidated basis is greater
                  than 60% of the sum of (i) Total Assets (as defined below) as
                  of the end of the calendar quarter covered in the Issuer's
                  Annual Report on Form 10-K or Quarterly Report on Form 10-Q,
                  as the case may be, most recently filed with the Trustee (or
                  such reports of the General Partner if filed by the Issuer
                  with the Trustee in lieu of filing its own reports) prior to
                  the incurrence of such additional Debt and (ii) the increase
                  in Total Assets from the end of such quarter including,
                  without limitation, any increase in Total Assets resulting
                  from the incurrence of such additional Debt (such increase,
                  together with the Total Assets, is referred to as "Adjusted
                  Total Assets").

                               In addition to the foregoing limitation on the
                  incurrence of Debt, the Issuer will not, and will not permit
                  any Subsidiary to, incur any Debt if the ratio of Consolidated
                  Income Available for Debt Service to the Annual Service Charge
                  (in each case as defined below) for the four consecutive
                  fiscal quarters most recently ended prior to the date on which
                  such additional Debt is to be incurred shall have been less
                  than 1.5 to 1, on a pro forma basis after giving effect to the
                  incurrence of such Debt and to the application of the proceeds
                  therefrom, and calculated on the assumption that (i) such Debt
                  and any other Debt incurred


                                       4
<PAGE>   5

                  by the Issuer or its Subsidiaries since the first day of such
                  four-quarter period and the application of the proceeds
                  therefrom, including to refinance other Debt, had occurred at
                  the beginning of such period, (ii) the repayment or retirement
                  of any other Debt by the Issuer or its Subsidiaries since the
                  first day of such four-quarter period had been incurred,
                  repaid or retired at the beginning of such period (except
                  that, in making such computation, the amount of Debt under any
                  revolving credit facility shall be computed based upon the
                  average daily balance of such Debt during such period), (iii)
                  the income earned on any increase in Adjusted Total Assets
                  since the end of such four-quarter period had been earned, on
                  an annualized basis, during such period, and (iv) in the case
                  of any acquisition or disposition by the Issuer or any
                  Subsidiary of any asset or group of assets since the first day
                  of such four-quarter period, including, without limitation, by
                  merger, stock purchase or sale, or asset purchase or sale,
                  such acquisition or disposition or any related repayment of
                  Debt had occurred as of the first day of such period with the
                  appropriate adjustments with respect to such acquisition or
                  disposition being included in such pro forma calculation.

                               In addition to the foregoing limitations on the
                  incurrence of Debt, the Issuer will not, and will not permit
                  any Subsidiary to, incur any Debt secured by any mortgage,
                  lien, charge, pledge, encumbrance or security interest of any
                  kind upon any of the property of the Issuer or any Subsidiary
                  ("Secured Debt"), whether owned at the date of the Indenture
                  or thereafter acquired, if, immediately after giving effect to
                  the incurrence of such additional Secured Debt, the aggregate
                  principal amount of all outstanding Secured Debt is greater
                  than 40% of Adjusted Total Assets.

                               For purposes of the foregoing provisions
                  regarding the limitation on the incurrence of Debt, Debt shall
                  be deemed to be "incurred" by the Issuer or a Subsidiary
                  whenever the Issuer and its Subsidiary shall create, assume,
                  guarantee or otherwise become liable in respect thereof.
                  Maintenance of Total Unencumbered Assets. The Issuer is
                  required to maintain Total Unencumbered Assets of not less
                  than 165% of the aggregate outstanding principal amount of all
                  outstanding Unsecured Debt.

                               As used herein:

                               "Annual Service Charge" as of any date means the
                  amount which is expensed in any 12-month period for interest
                  on Debt of the Issuer and its Subsidiaries.

                               "Consolidated Income Available For Debt Service"
                  for any period means Consolidated Net Income plus amounts
                  which have been deducted for (a) interest on Debt of the
                  Issuer and its Subsidiaries, (b) provision for taxes of the
                  Issuer and its Subsidiaries based on income, (c) amortization
                  of Debt discount, (d) provisions for gains and losses on
                  properties, (e) depreciation and amortization, (f) the effect
                  of any noncash charge resulting from a change in


                                       5
<PAGE>   6

                  accounting principles in determining Consolidated Net Income
                  for such period and (g) amortization of deferred charges.

                               "Consolidated Net Income" for any period means
                  the amount of consolidated net income (or loss) of the Issuer
                  and its Subsidiaries for such period determined on a
                  consolidated basis in accordance with generally accepted
                  accounting principles.

                               "Debt" of the Issuer or any Subsidiary means any
                  indebtedness of the Issuer or such Subsidiary, as applicable,
                  whether or not contingent, in respect of (i) borrowed money
                  evidenced by bonds, notes, debentures or similar instruments,
                  (ii) indebtedness secured by any mortgage, pledge, lien,
                  charge, encumbrance or any security interest existing on
                  property owned by the Issuer or such Subsidiary, (iii) the
                  reimbursement obligations, contingent or otherwise, in
                  connection with any letters of credit actually issued or
                  amounts representing the balance that constitutes an accrued
                  expense or trade payable or (iv) any lease of property by the
                  Issuer or such Subsidiary as lessee which is reflected in the
                  Issuer's consolidated balance sheet as a capitalized lease in
                  accordance with generally accepted accounting principles, in
                  the case of items of indebtedness under (i) through (iii)
                  above to the extent that any such items (other than letters of
                  credit) would appear as a liability on the Issuer's
                  consolidated balance sheet in accordance with generally
                  accepted accounting principles, and also includes, to the
                  extent not otherwise included, any obligation by the Issuer or
                  such Subsidiary to be liable for, or to pay, as obligor,
                  guarantor or otherwise (other than for purposes of collection
                  in the ordinary course of business), indebtedness of another
                  person (other than the Issuer or any Subsidiary).

                  long as no senior class of stock has such voting power by

                  determined in accordance with generally accepted accounting
                  principles (but excluding intangibles and accounts
                  receivable).

                               "Total Unencumbered Assets" as of any date means
                  the sum of (i) those Undepreciated Real Estate Assets which

                  the owner thereof to secure Debt, excluding infrastructure
                  assessment bonds, and (ii) all other assets of the Issuer and

                  consolidated basis in accordance with generally accepted

         such interests for 2016 Notes of like tenor or any authorized form and
         denomination only in the manner provided in Section 305 of the
         Indenture. DTC shall be the depository with respect to the permanent
         global 2016 Note.

         Regular Record Date for such interest.

                  (18)     Sections 1402 and 1403 of the Indenture shall be
         applicable to the 2016 Notes.

                  (19)     The 2016 Notes shall not be issuable in definitive
         form except under the circumstances described in Section 305 of the

                  (22)     The 2016 Notes shall not be subordinated to any other
         debt of the Issuer, and shall constitute senior unsecured obligations
         of the Issuer.

                        7.875% NOTE DUE DECEMBER 1, 2016


         SPIEKER PROPERTIES, L.P., a California limited partnership (the
"Issuer"), for value received, hereby promises to pay to Cede & Co., or
registered assignee (the "Holder"), upon presentation, the principal sum of
$25,000,000 on December 1, 2016, and to pay interest on the outstanding
principal amount thereon from December 10, 1996, or from the most recent
Interest Payment Date to which interest has been paid or duly provided for,
semi-annually in arrears on December 1 and June 1 in each year (each an
"Interest Payment Date"), commencing June 1, 1997, and at the Stated Maturity,
at the rate of 7.875% per annum, computed on the basis of a 360-day year
comprised of twelve 30-day months, until the entire principal amount hereof is
paid or duly provided for. The interest so payable, and punctually paid or duly
provided for on any Interest Payment Date will, as provided in the Indenture
(hereinafter defined), be paid to the person in whose name this Note (the "2016
Note") (or one or more predecessor 2016 Notes) is registered at the close of
business on the Regular Record Date for such Interest Payment Date which shall
be the 15th calendar day preceding the applicable Interest Payment Date. Any
such interest not so punctually paid or duly provided for shall forthwith cease
to be payable to the Holder on such Regular Record Date, and may either be paid
to the Person in whose name this 2016 Note (or one or more predecessor 2016
Notes) is registered at the close of business on a Special Record Date for the
payment of such Defaulted Interest to be fixed by the Trustee, notice whereof
shall be given to Holders of 2016 Notes not more than 15 days and not less than
10 days prior to such Special Record Date, or may be paid at any time in any
other lawful manner not inconsistent with the requirements of any securities
exchange on which the 2016 Notes may be listed, and upon such notice as may be
required by such exchange, all as more fully provided in the Indenture. Payments
of the principal of, and interest on, this 2016 Note will be made at the office
or agency of the Trustee (hereinafter defined) maintained for that purpose at


                                       1
<PAGE>   12

Two International Place, Boston, Massachusetts 02110, or elsewhere as provided
in the Indenture, in United States Dollars; provided, however, that at the
option of the Holder hereof, and upon written notice to the Trustee of not less
than five Business Days prior to the applicable Interest Payment Date, payment
of interest may be made by (i) check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register kept for
the 2016 Notes pursuant to Section 305 of the Indenture (the "2016 Note
Register") or (ii) transfer to an account of the Person entitled thereto located
inside the United States.

         This 2016 Note is one of a fully authorized issue of securities of the
Issuer issued as a series of securities issued and to be issued under an
Indenture, dated as of December 6, 1995 and the Seventh Supplemental Indenture
dated December 10, 1996 (collectively, the "Indenture"), among the Issuer and
State Street Bank and Trust Company (the "Trustee," which term includes any
successor trustee under the Indenture with respect to the 2016 Notes), to which
Indenture and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, duties and immunities
thereunder of the Issuer, the Trustee and the Holders of the 2016 Notes, and of
the terms upon which the 2016 Notes are, and are to be, authenticated and
delivered. This 2016 Note is one of the series designated as the "7.875% Notes
Due December 1, 2016," limited in the aggregate principal amount to $25,000,000.

         The 2016 Notes may be redeemed at any time at the option of the Issuer,
in whole or from time to time in part, at a redemption price (the "Redemption
Price") equal to the sum of (i) the principal amount of the 2016 Notes (or
portion thereof) being redeemed plus accrued interest thereon to the redemption
date and (ii) the Make-Whole Amount (as defined below), if any, with respect to
such 2016 Notes (or portion thereof).

         If notice has been given as provided in the Indenture and funds for the
redemption of any 2016 Notes (or any portion thereof) called for redemption
shall have been made available on the redemption date referred to in such
notice, such 2016 Notes (or any portion thereof) will cease to bear interest on
the date fixed for such redemption specified in such notice and the only right
of the Holders of the 2016 Notes will be to receive payment of the Redemption
Price, with respect to such 2016 Notes or portion thereof so redeemed.

         Notice of any optional redemption of any 2016 Notes (or any portion
thereof) will be given to Holders at their addresses, as shown in the 2016 Note
Register, not more than 60 nor less than 30 days prior to the date fixed for
redemption. The notice of redemption will specify, among other items, the
Redemption Price and the principal amount of the 2016 Notes held by such Holder
to be redeemed.

         The Issuer will notify the Trustee at least 45 days prior to giving
notice of redemption (or such shorter period as is satisfactory to the Trustee)
of the aggregate principal amount of 2016 Notes to be redeemed and their
redemption date. If less than all the 2016 Notes are to be redeemed at the
option of the Issuer, the Trustee shall select, in such manner as it shall deem
fair and appropriate, the 2016 Notes to be redeemed in whole or in part.


                                       2
<PAGE>   13

         In the event of redemption of the 2016 Notes in part only, a new 2016
Note for the amount of the unredeemed portion hereof shall be issued in the name
of the Holder hereto, upon cancellation hereof.

         As used herein:

         "Make-Whole Amount" means, in connection with any optional redemption
or accelerated payment of any 2016 Notes, the excess, if any, of (i) the
aggregate present value as of the date of such redemption or accelerated payment
of each dollar of principal being redeemed or paid and the amount of interest
(exclusive of interest accrued to the date of redemption or accelerated payment)
that would have been payable in respect of each such dollar if such redemption
or accelerated payment had not been made, determined by discounting, on a
semi-annual basis, such principal and interest at the Reinvestment Rate
(determined on the third Business Day preceding the date such notice of
redemption is given or declaration of acceleration is made) from the respective
dates on which such principal and interest would have been payable if such
redemption or accelerated payment had not been made, over (ii) the aggregate
principal amount of the 2016 Notes being redeemed or paid.

         "Reinvestment Rate" means 0.25% plus the arithmetic mean of the yields
under the respective heading "Week Ending" published in the most recent
Statistical Release under the caption "Treasury Constant Maturities" for the
maturity (rounded to the nearest month) corresponding to the remaining life to
maturity, as of the payment date of the principal being redeemed or paid. If no
maturity exactly corresponds to such maturity, yields for the two published
maturities most closely corresponding to such maturity shall be calculated
pursuant to the immediately preceding sentence and the Reinvestment Rate shall
be interpolated or extrapolated from such yields on a straight-line basis,
rounding in each of such relevant periods to the nearest month. For the purpose
of calculating the Reinvestment Rate, the most recent Statistical Release
published prior to the date of determination of the Make-Whole Amount shall be
used.

         "Statistical Release" means the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded United
States government securities adjusted to constant maturities, or, if such
statistical release is not published at the time of any determination under the
Indenture, then such other reasonably comparable index which shall be designated
by the Issuer.

         The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of the Issuer on this 2016 Note and (b) certain restrictive
covenants and the related defaults and Events of Default applicable to the
Issuer, in each case, upon compliance by the Issuer with certain conditions set
forth in the Indenture, which provisions apply to this 2016 Note.

         The Issuer is subject to certain covenants contained in the Indenture
with respect to, and for the benefit of the Holders of, the 2016 Notes. The
Trustee shall not be obligated to monitor or confirm, on a continuing basis or
otherwise, the Issuer's compliance with the covenants


                                       3
<PAGE>   14

contained in the Indenture or with respect to reports or other certificates
filed under the Indenture; provided, however, that nothing herein shall relieve
the Trustee of any obligations to monitor the Issuer's timely delivery of all
reports and certificates required under Sections 703 and 1005 of the Indenture
and to fulfill its obligations under Article Six of the Indenture.

         If an Event of Default as defined in the Indenture with respect to the
2016 Notes shall occur and be continuing, the principal of the 2016 Notes may be
declared due and payable in the manner and with the effect provided in the
Indenture.

         As provided in and subject to the provisions of the Indenture, the
Holder of this 2016 Note shall not have the right to institute any proceeding
with respect to the Indenture or for the appointment of a receiver or trustee or
for any other remedy thereunder, unless such Holder shall have previously given
the Trustee written notice of a continuing Event of Default with respect to the
2016 Notes, the Holders of not less than a majority in principal amount of the
2016 Notes at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity and shall have failed to institute
any such proceeding, for 60 days after receipt of such notice, request and offer
of indemnity and the Trustee shall not have received from the Holders of a
majority in principal amount of the 2016 Notes at the time Outstanding a
direction inconsistent with such request. The foregoing shall not apply to any
suit instituted by the Holder of this 2016 Note for the enforcement of any
payment of principal hereof or any interest on or after the respective due dates
expressed herein.

         The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Issuer and the rights of the Holders of the 2016 Notes under the Indenture at
any time by the Issuer and the Trustee with the consent of the Holders of not
less than a majority in principal amount of the Outstanding 2016 Notes. The
Indenture also contains provisions permitting the Holders of not less than a
majority in principal amount of the 2016 Notes at the time Outstanding, on
behalf of the Holders of all 2016 Notes, to waive compliance by the Issuer with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this 2016 Note shall be conclusive and binding upon such Holder and upon all
future Holders of this 2016 Note and of any 2016 Note issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this 2016 Note.

         No reference herein to the Indenture and no provision of this 2016 Note
or of the Indenture shall alter or impair the obligation of the Issuer, which is
absolute and unconditional, to pay the principal of, and interest on, this 2016
Note at the times, place and rate, and in the coin or currency, herein
prescribed.

         As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this 2016 Note is registrable in the 2016 Note
Register, upon surrender of this 2016 Note for registration of transfer at the
