Interest on this Note shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. The interest so payable and punctually paid or duly provided for on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be January 1 or July 1 (whether or not a Business Day), as the case may be, immediately preceding such Interest Payment Date. Any such interest which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the registered Holder hereof on the relevant Regular Record Date by virtue of having been such Holder, and may be paid to the Person in whose name this Note (or one or more

Predecessor Securities) 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 the Holder of this Note 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 Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in such Indenture.

Payment of the principal of and the interest on this Note will be made at the office or agency of the Operating Partnership maintained for that purpose in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that, at the option of the Operating Partnership, interest may be paid by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or by wire transfer to an account maintained by the payee located in the United States of America.

This Note is one of a duly authorized issue of Securities of the Operating Partnership (herein called the “Notes”) issued and to be issued under an Indenture dated as of June 30, 1998 (herein called, together with all indentures supplemental thereto, the “Indenture”) among, the Operating Partnership, AMB Property Corporation and U.S. Bank National Association, as successor-in-interest to State Street Bank and Trust Company of California, N.A., as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), 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 Operating Partnership, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the Securities of the series designated on the face hereof, limited in aggregate principal amount to $175,000,000.

The Notes are subject to redemption prior to the Stated Maturity of the principal thereof as provided in the Indenture.

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

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Operating Partnership and the rights of the Holders of the Notes of each series issued under the Indenture at any time by the Operating Partnership and the Trustee with the consent of the Holders of not less than a majority in aggregate principal amount of the Notes at the time Outstanding of each series affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Notes of any series at the time Outstanding, on behalf of the Holders of all Notes of such series, to waive compliance by the Operating Partnership 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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Notes 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 Note.

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

As provided in the Indenture and subject to certain limitations set forth therein, the transfer of this Note may be registered on the Security Register upon surrender of this Note for registration of transfer at the office or agency of the Operating Partnership maintained for the purpose in any place where the principal of and interest on this Note are payable, duly endorsed, or accompanied by a written instrument of transfer in form satisfactory to the Operating Partnership and the Security Registrar duly executed by the Holder hereof or by his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. The Notes are issuable only in registered form without coupons in the denominations of $1,000 and integral multiples thereof. As provided in the Indenture and subject to certain limitations set forth therein, the Notes are exchangeable for a like aggregate principal amount of Notes of authorized denominations as requested by the Holders surrendering the same.

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

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

The Indenture contains provisions whereby (i) the Operating Partnership may be discharged from its obligations with respect to the Notes (subject to certain exceptions) or (ii) the Operating Partnership may be released from its obligations under specified covenants and agreements in the Indenture, in each case if the Operating Partnership irrevocably deposits with the Trustee money or Government Obligations sufficient to pay and discharge the entire indebtedness on all Securities, and satisfies certain other conditions, all as more fully provided in the Indenture.

THIS NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

Capitalized terms used in this Note which are not defined herein shall have the meanings assigned to them in the Indenture.

Unless the certificate of authentication hereon has been executed by or on behalf of the Trustee under the Indenture by the manual signature of one of its authorized signatories, this Note shall not be entitled to any benefits under the Indenture or be valid or obligatory for any purpose.

THIS PARENT GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

This Parent Guarantee shall not be valid or obligatory for any purpose until the certificate of authentication on the Note shall have been executed by the Trustee under the Indenture referred to above by the manual signature of one of its authorized officers. The validity and enforceability of this Parent Guarantee shall not be affected by the fact that it is not affixed to any particular Note.

An Event of Default under the Indenture or the Notes shall constitute an event of default under this Parent Guarantee, and shall entitle the Holders of Notes to accelerate the obligations of the undersigned hereunder in the same manner and to the same extent as the obligations of the Operating Partnership.

Notwithstanding any other provision of this Parent Guarantee to the contrary, the undersigned hereby waives any claims or other rights which it may now have or hereafter acquire against the Operating Partnership that arise from the existence or performance of its obligations under this Parent Guarantee (all such claims and rights are referred to as “Guarantor’s Conditional Rights”), including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, or indemnification, any right to participate in any claim or remedy against the Operating Partnership, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, by any payment made hereunder or otherwise, including without limitation, the right to take or receive from the Operating Partnership, directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such claim or other rights. Guarantor hereby agrees not to exercise any rights which may be acquired by way of contribution under this Parent Guarantee or any other agreement, by any payment made hereunder or otherwise, including, without limitation, the right to take or receive from any other guarantor, directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such contribution rights. If, notwithstanding the foregoing provisions, any amount shall be paid to the undersigned on account of the Guarantor’s Conditional Rights and either (i) such amount is paid to such undersigned party at any time when the indebtedness shall not have been paid or performed in full, or (ii) regardless of when such amount is paid to such undersigned party, any payment made by the Operating Partnership to a Holder that is at any time determined to be a Preferential Payment (as defined below), then such amount paid to the undersigned shall be held in trust for the benefit of Holder and shall forthwith be paid such Holder to be credited and applied upon the indebtedness, whether matured or unmatured. Any such payment is herein referred to as a “Preferential Payment” to the extent the Operating Partnership makes any payment to Holder in connection with the Note, and any or all of such payment is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid or paid over to a trustee, receiver or any other entity, whether under any bankruptcy act or otherwise.

To the extent that any of the provisions of the immediately preceding paragraph shall not be enforceable, the undersigned agrees that until such time as the indebtedness has been paid and performed in full and the period of time has expired during which any payment made by the Operating Partnership or the

undersigned to a Holder may be determined to be a Preferential Payment, Guarantor’s Conditional Rights to the extent not validly waived shall be subordinate to Holders’ right to full payment and performance of the indebtedness and the undersigned shall not enforce any of Guarantor’s Conditional Rights until such time as the indebtedness has been paid and performed in full and the period of time has expired during which any payment made by the Operating Partnership or the undersigned to Holders may be determined to be a Preferential Payment.

The obligations of the undersigned to the Holders of the Notes and to the Trustee pursuant to this Parent Guarantee and the Indenture are expressly set forth in Article 14 of the Indenture and reference is hereby made to the Indenture for the precise terms of this Parent Guarantee and all of the other provisions of the Indenture to which this Parent Guarantee relates.

(the “Operating Partnership”) under an Indenture dated as of June 30, 1998 (together with the First Supplemental Indenture thereto, the Second Supplemental Indenture thereto, the Third Supplemental Indenture thereto, the Fourth Supplemental Indenture thereto, the Fifth Supplemental Indenture thereto, the Sixth Supplemental Indenture thereto, the Seventh Supplemental Indenture thereto, the Eighth Supplemental Indenture thereto, the Ninth Supplemental Indenture thereto, the Tenth Supplemental Indenture thereto and the Eleventh Supplemental Indenture thereto, the “Indenture”) among the Operating Partnership, AMB Property Corporation, and U.S. Bank National Association, as successor-in-interest to State Street Bank and Trust Company of California, N.A., as trustee hereunder (the “Trustee”), (a) the full and prompt payment of the principal of and premium, if any, on such Note when and as the same shall become due and payable, whether at Stated Maturity, by acceleration, by redemption or otherwise, and (b) the full and prompt payment of the interest on such Note when and as the same shall become due and payable, according to the terms of such Note and of the Indenture. The undersigned hereby agrees, jointly and severally with the Parent Guarantor pursuant to the Parent Guarantee and any other Subsidiary Guarantors under their respective Subsidiary Guarantees, that its obligations hereunder shall be as principal and not merely as surety, and shall be absolute and unconditional, and shall not be affected, modified or impaired by the following: (a) the failure to give notice to the Guarantors of the occurrence of an Event of Default under the Indenture; (b) the waiver, surrender, compromise, settlement, release or termination of the payment, performance or observance by the Operating Partnership or the Guarantors of any or all of the obligations, covenants or agreements of either of them contained in the Indenture or the Notes; (c) the acceleration, extension or any other changes in the time for payment of any principal of or interest or any premium on any Note or for any other payment under the Indenture or of the time for performance of any other obligations, covenants or agreements under or arising out of the Indenture or the Notes; (d) the modification or amendment (whether material or otherwise) of any obligation, covenant or agreement set forth in the Indenture or the Notes; (e) the taking or the omission of any of the actions referred to in the Indenture and in any of the actions under the Notes; (f) any failure, omission, delay or lack on the part of the Trustee to enforce, assert or exercise any right, power or remedy conferred on the Trustee in the Indenture, or any other action or acts on the part of the Trustee or any of the Holders from time to time of the Notes; (g) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition with creditors or readjustment of, or other similar proceedings affecting the Guarantors or the Operating Partnership or any of the assets of any of them, or any allegation or contest of the validity of this Subsidiary Guarantee in any such proceeding; (h) to the extent permitted by law, the release or discharge by operation of law of the Guarantors from the performance or observance of any obligation, covenant or agreement contained in the Indenture; (i) to the extent permitted by law, the release or discharge by operation of law of the Operating Partnership from the performance or observance of any obligation, covenant or agreement contained in the Indenture; (j) the default or failure of the Operating Partnership or the Trustee fully to perform any of its obligations set forth in the Indenture or the Notes; (k) the invalidity, irregularity or unenforceability of the Indenture or the Notes or any part of any thereof; (l) any judicial or governmental action affecting the Operating Partnership or any Notes or consent or indulgence granted to the Operating Partnership by the Holders or by the Trustee; or (m) the recovery of any judgment against the Operating Partnership or any action to enforce the same or any other circumstance which might constitute a legal or equitable discharge of a surety or guarantor. The undersigned hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of merger, sale, lease or conveyance of all or substantially all of its assets,

insolvency or bankruptcy of the Operating Partnership, any right to require a proceeding first against the Operating Partnership, protest or notice with respect to such Notice or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Subsidiary Guarantee will not be discharged except by complete performance of the obligations contained in such Note and in this Subsidiary Guarantee. No reference herein to such Indenture and no provision of this Subsidiary Guarantee or of such Indenture shall alter or impair the guarantee of the undersigned, which is absolute and unconditional, of the full and prompt payment of the principal of and premium, if any, and interest on the Note.

THIS SUBSIDIARY GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK.

The validity and enforceability of this Subsidiary Guarantee shall not be affected by the fact that it is not affixed to any particular Note.

An Event of Default under the Indenture or the Notes shall constitute an event of default under this Subsidiary Guarantee, and shall entitle the Holders of Notes to accelerate the obligations of the undersigned hereunder in the same manner and to the same extent as the obligations of the Operating Partnership.

Notwithstanding any other provision of this Subsidiary Guarantee to the contrary, the undersigned hereby waives any claims or other rights which it may now have or hereafter acquire against the Operating Partnership that arise from the existence or performance of its obligations under this Subsidiary Guarantee (all such claims and rights are referred to as “Guarantor’s Conditional Rights”), including, without limitation, any right of subrogation, reimbursement, exoneration, contribution, or indemnification, any right to participate in any claim or remedy against the Operating Partnership, whether or not such claim, remedy or right arises in equity or under contract, statute or common law, by any payment made hereunder or otherwise, including without limitation, the right to take or receive from the Operating Partnership, directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such claim or other rights. The Subsidiary Guarantor hereby agrees not to exercise any rights which may be acquired by way of contribution under this Subsidiary Guarantee or any other agreement, by any payment made hereunder or otherwise, including, without limitation, the right to take or receive from any other guarantor, directly or indirectly, in cash or other property or by setoff or in any other manner, payment or security on account of such contribution rights. If, notwithstanding the foregoing provisions, any amount shall be paid to the undersigned on account of any such Guarantor’s Conditional Rights and either (i) such amount is paid to such undersigned party at any time when the indebtedness shall not have been paid or performed in full, or (ii) regardless of when such amount is paid to such undersigned party, any payment made by Operating Partnership to a Holder that is at any time determined to be a Preferential Payment (as defined below), then such amount paid to any of the undersigned shall be held in trust for the benefit of the Holders and shall forthwith be paid such Holder to be credited and applied upon the indebtedness, whether matured or unmatured. Any such payment is herein referred to as a “Preferential Payment” to the extent the Operating Partnership makes any payment to the Holders in connection with the Note, and any or all of such payment is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be repaid or paid over to a trustee, receiver or any other entity, whether under any bankruptcy act or otherwise.

To the extent that any of the provisions of the immediately preceding paragraph shall not be enforceable, each of the undersigned agrees that until such time as the indebtedness has been paid and performed in full and the period of time has expired during which any payment made by the Operating Partnership or the undersigned to a Holder may be determined to be a Preferential Payment, Guarantor’s Conditional Rights to the extent not validly waived shall be subordinate to Holders’ right to full payment and performance of the indebtedness and each of the undersigned shall not enforce any of its respective

portion of the Guarantors’ Conditional Rights until such time as the indebtedness has been paid and performed in full and the period of time has expired during which any payment made by the Operating Partnership or the undersigned to Holders may be determined to be a Preferential Payment.

The undersigned’s liability shall be that amount from time to time equal to the aggregate liability of the undersigned hereunder, but shall be limited to the lesser of (A) the aggregate amount of the obligation as stated in the second sentence of Section 1401 of the Indenture, and (B) the amount, if any, which would not have (i) rendered the undersigned “insolvent” (as such term is defined in Section 101(29) of the Federal Bankruptcy Code and in Section 271 of the Debtor and Creditor Law of the State of New York, as each is in effect at the date of the Indenture) or (ii) left the undersigned with unreasonably small capital at the time its Guarantee was entered into, after giving effect to the incurrence of existing Debt (as defined in the Indenture) immediately prior to such time, provided that, it shall be a presumption in any lawsuit or other proceeding in which the undersigned is a party that the amount guaranteed is the amount set forth in (A) above unless a creditor, or representative of creditors of the undersigned or a trustee in bankruptcy of the undersigned, as debtor in possession, otherwise proves in such a lawsuit that the aggregate liability of the undersigned is limited to the amount set forth in (B). In making any determination as to the solvency or sufficiency of capital of the undersigned in accordance with the previous sentence, the right of the undersigned to contribution from other Guarantors, to subrogation and any other rights the undersigned may have, contractual or otherwise, shall be taken into account.

The obligations of the undersigned to the Holders of the Notes and to the Trustee pursuant to the Subsidiary Guarantee and the Indenture are expressly set forth in Article 14 of the Indenture and reference is hereby made to the Indenture for the precise terms of the Subsidiary Guarantee and all of the other provisions of the Indenture to which this Subsidiary Guarantee relates.

Capitalized terms in this Subsidiary Guarantee which are not defined herein shall have the meanings assigned to them in the Indenture.

IN WITNESS WHEREOF, the undersigned has caused this Subsidiary Guarantee to be duly executed.
