discretion and (ii) will keep the Property free from all liens and encumbrances other than the lien of this Deed of Trust, the Permitted Exceptions, and any other lien approved by Lender in its sole discretion. A Transfer

sole discretion. Notwithstanding the foregoing sentence, if that certain Amended and Restated Agreement of Limited Partnership of Catellus Operating Limited Partnership (the Partnership Agreement), dated
, 2003, as set forth in that certain Proxy Statement/Prospectus dated August 15, 2003, is amended at anytime such that the

(a) Without limiting its other obligations herein, Borrower executes this Deed of Trust for the purpose of (i) securing payment and
performance of the Obligations (including those certain Obligations as defined in the Crossed Deeds of Trust), even though Borrower is not personally liable for the payment or performance of certain Obligations; and (ii) conveying to
Trustee all of Borrowers right, title and interest in and to the Property and to each of the provisions of this Deed of Trust.



(b) Borrower agrees that any and all conditions precedent or subsequent to subjecting its interest in the Property to the lien of
this Deed of Trust have either been satisfied or are expressly and irrevocably waived. Borrower has no defense to the foreclosure of this Deed of Trust or the enforcement of any remedy provided for herein or in any other document evidencing the Loan
or the Crossed Loans and agrees that this Deed of Trust shall at all times be and remain a valid first and prior lien and charge upon its interest in the Property for the repayment of the full indebtedness secured hereby and any renewal or
extensions thereof without regard to any act or omission of SFPP, Trustee or Lender, either past, present or future. Without limiting the foregoing, Borrower hereby waives the benefits of any right of discharge under any and all statutes or other
laws relating to guarantors or sureties and any other rights of sureties and guarantors thereunder, including without limitation, diligence, presentment, demand for payment, protest, and all notices which may be required by statute, rule of law or

a surety that:



(A) it waives the rights and
benefits under Civil Code Section 2819, and that its liability shall continue even if Lenders remedies or rights against SFPP are in any way impaired or suspended without Borrowers consent;



(B) it waives any and all benefits and defenses under Civil
Code Section 2810 and Borrower is liable even if SFPP had no liability at the time of execution of the Note, the other Loan Documents, the Loan Documents as defined in the Crossed Deeds of Trust, or thereafter ceased to be liable;



(C) it waives any and all benefits and
defenses under Civil Code Section 2809 and agrees that its liability may be larger in amount and more burdensome than that of SFPP;



(D) it waives any and all benefits and defenses under Civil Code Sections 2845, 2849, 2850, 2899 and 3433, including, without limitation,
any right to require Lender to (i) proceed against SFPP or any other pledgor, or (ii) pursue any other right or remedy for Borrowers benefit, and agrees that Lender may proceed against Borrowers right, title and interest in the Land and
the other Property for the Obligations without taking any action against SFPP or any other pledgor and except as expressly provided herein to the contrary without proceeding against any other collateral Lender holds;



(E) Lender may unqualifiedly exercise, in its sole and
absolute discretion, any or all rights and remedies available to it against SFPP or any other pledgor without impairing Lenders rights and remedies in enforcing the Obligations against Borrower; and



(F) Lenders exercise of certain of such rights or
remedies may affect or eliminate Borrowers right of subrogation or recovery against SFPP or another pledgor and that Borrower may incur partially or totally non-reimbursable liability under this Deed of Trust.



(ii) Borrower hereby waives all benefits and defenses under
Civil Code Sections 2847, 2848 and 2849 and agrees that Borrower shall have no right of subrogation or reimbursement against SFPP or any other pledgor, no right of subrogation against any collateral or security provided for in the Loan Documents or
in the Loan Documents as defined in the Crossed Deeds of Trust and no right of contribution against any other pledgor unless and until all amounts due under the Loan Documents and under the Loan Documents as defined in the
Crossed Deeds of Trust have been paid in full and Lender has released, transferred or disposed of all of its right, title and interest in the



-11-



---

Property and each Property as defined in each of the Crossed Deeds of Trust. To the extent
any Borrowers waiver of these rights of subrogation, reimbursement or contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, Borrower agrees that Borrowers rights of
subrogation and reimbursement against SFPP or any other pledgor and right of subrogation against any collateral or security shall be unconditionally junior and subordinate to Lenders rights against SFPP and to Lenders right, title and
interest in such collateral or security, and Borrowers right of contribution against SFPP or any other pledgor shall be unconditionally junior and subordinate to Lenders rights against such party.



(iii) Borrower agrees that it shall not be released or
discharged, in whole or in part, by (i) Lenders failure to perfect or continue the perfection of any lien or security interest in collateral which secures the Obligations, (ii) Lenders failure to protect the property covered by such lien
or security interest, or (iii) any consent by Lender to the transfer, subordination, release, substitution or liquidation of any portion of the collateral which secures the Obligations.



(iv) So long as any of the Obligations shall remain owing to Lender, Borrower shall not, without the prior
written consent of Lender, commence or join with any other party in commencing any bankruptcy, reorganization or insolvency proceedings of Borrower or against SFPP or any other pledgor.



(v) Borrowers waivers herein are made knowing that their intent is to deprive Borrower of the benefits
and defenses that would or could otherwise be available to Borrower as a guarantor under the statutory provisions and case law referenced herein.



(vi) If any payment by SFPP is held to constitute a preference under any applicable bankruptcy or similar laws, or if for any reason
Lender is required to refund any sums to SFPP, such amounts shall not constitute a release of any liability hereunder. It is the intention of Lender and Borrower that Borrowers obligations hereunder shall not be discharged except by
SFPPs performance of such obligations and then only to the extent of such performance.



(vii) Borrower agrees that any indebtedness of SFPP now or hereafter held by Borrower is hereby and shall be unconditionally subordinated
to all indebtedness of SFPP to Lender and any such indebtedness of SFPP shall be collected, enforced and received by Borrower, as trustee for Lender, but without reducing or affecting in any manner the liability of Borrower for the Obligations.



(viii) Borrower hereby waives all rights and
remedies arising out of an election of remedies by Lender, even though, that election of remedies, such as non-judicial foreclosure with respect to security for the Obligations, has destroyed Borrowers rights of subrogation and reimbursement
against SFPP or any other pledgor. In addition, Borrower hereby waives all defenses that Borrower may have because the Obligations are secured by real property in addition to the Property.



(ix) Borrower acknowledges that nothing contained in the
Deed of Trust shall affect any of SFPPs or any Borrowers obligations under any lease agreement relating to the Property.



-12-



---

(x) Borrower further acknowledges that:



(A) Lender would not make the Loan and the Crossed Loans
without the agreements in this Deed of Trust;



(B) Borrower consents to, and approves of, the instructions of SFPP to Lender as to the disbursement of the proceeds of the Loan and/or the Crossed Loans, as applicable;



(C) Lender in making such disbursement is under no obligation or duty to, nor has Lender represented that
it will see to, the application of such proceeds and any application or use of such proceeds for any purpose shall not defeat the encumbrance hereby made either in whole or in part;



(D) Borrower intentionally and unconditionally subjects its interests in the Property to the lien and
charge of this Deed of Trust and understands that, in reliance upon, and in consideration of so doing, specific loans and advances are being, and will be made, and specific monetary and other obligations are being, and will be, entered into which
would not be made or entered into but for said reliance upon such encumbrance;



(E) SFPPs performance of any of Borrowers obligations herein shall be deemed to be performance by Borrower to the extent
performed by SFPP and



(F) the making of the
Loan will benefit Borrower.

Exhibit C



(Substitution Provisions)



The obligations of Lender to agree to a Substitution are subject to the fulfillment by Borrower, or waiver by Lender, of the following conditions
precedent (the Substitution Conditions) no later than the earlier of the date of the Substitution or as otherwise specified:



3.3(f).1. Representations and Warranties. The representations and warranties of Borrower contained in all of the Loan Documents shall be
true and correct in all material respects on and as of the date of the Substitution with respect to the Substitution Property and the ownership thereof with the same effect as if made on and as of such date.



3.3(f).2. Deliverables. Borrower shall deliver to Lender the
following items, all to be satisfactory to Lender, in its sole discretion, and Borrower hereby acknowledges that Lenders receipt of such items does not constitute Lenders approval of such items:



(a) not less than forty-five (45) days before the date of the Substitution,
originals or certified copies of all operating agreements, ground leases, reciprocal easement agreements, management agreements and other material agreements affecting each of the Substitution Properties (collectively, the Property
Documents) and copies of all Leases affecting each of the Substitution Properties, together with any short form leases, amendments, addenda, exhibits or assignments thereto, and as soon as practicable after execution thereof, originals
or certified copies of all such Property Documents and Leases executed after the initial delivery of such Property Documents and Leases. After Lenders approval, with respect to the Substitution Property, none of the foregoing may be amended
prior to the date of the Substitution without Lenders prior written consent;



(b) not less than thirty (30) days before the date of the Substitution, two copies of the Borrowers standard form lease for the Substitution Property, which may not be amended prior to the date of the
Substitution without Lenders prior written consent;



(c)
not less than forty-five (45) days before the date of the Substitution, plans and specifications for the Improvements for each of the Substitution Properties, provided, however, Lenders approval of plans and specifications for the Substitution
Property shall only be required with respect to Improvements which are less than five (5) years old;



(d) not less than forty-five (45) days before the date of the Substitution, a current title report or binder (including the fee underlying any leasehold
estate) for the Substitution Property and searches of appropriate UCC records;



(e) not less than thirty (30) days before the date of the Substitution, a Survey for the Substitution Property certified to Lender and its title insurer in form acceptable to Lender;



(f) not less than thirty (30) days before the date of the Substitution, a pro
forma certification of the rent roll for each of the Substitution Property, which shall be revised to include all new and/or amended information arising after the certification was initially certified by Borrower not more than fifteen (15) days and
not less than five (5) days before the date of the Substitution;



-5-



---

(g) with respect to the Substitution Property, not less than thirty (30) days before the date of the
Substitution, evidence satisfactory to Lender that the Substitution Property is covered by Borrowers approved insurance program including coverage for terrorism insurance. Borrower shall maintain insurance covering acts of terrorism, provided
such insurance is available at commercially reasonable rates (as determined by Lender annually). If Borrowers blanket coverage is provided by multiple insurers, such terrorism coverage shall be included in policies issued for 80% of the
coverage amount given by such insurers;



(h) not less than ten
(10) Business Days before the date of the Substitution, (i) an architects certificate, in form and content acceptable to Lender, for the Substitution Property, (ii) an original or certified copy of all building permits for the Substitution
Property, if required by Lender, and an original or certified copy of the unconditional certificate of occupancy or other unconditional certificate of appropriate governmental authorities having jurisdiction permitting occupancy of the Substitution
Property evidencing compliance with all zoning, building and applicable regulations for the Substitution Property, and (iii) a copy of all other consents, permits, licenses, approvals and franchises referenced in Section 3.3(f).4 below;



(i) not less than five (5) days before the date of the
Substitution, original tenant estoppel certificates for Leases affecting the Substitution Property, dated not more than thirty (30) days before the date of the Substitution, and original subordination, non-disturbance and attornment agreements, duly
executed, acknowledged and delivered by landlord and tenant, for all Leases for more than 15,000 square feet of premises;



(j) not more than forty-five (45) days and not less than five (5) days before the date of the Substitution, original estoppel certificates, dated not more
than thirty (30) days before the date of the Substitution, from all parties to Property Documents including, but not limited to, any operating agreements, ground leases, and reciprocal easement agreements affecting the Substitution Property;



(k) not less than thirty (30) days before the date of the
Substitution, a certified inventory of Fixtures and Personal Property at the Substitution Property;



(l) not less than thirty (30) days before the date of the Substitution, copies of bills and assessments for Taxes for each of the Substitution Properties,
along with verification of payment of such Taxes for the current tax year and for the previous tax year;



(m) not less than fifteen (15) days before the date of the Substitution, a form of opinion prepared by counsel satisfactory to Lender, substantially
similar to the form of opinion prepared by counsel to Borrower for the Loan, covering such legal matters as Lender deems appropriate with respect to the Substitution, including due authorization, due execution, enforceability, usury, and due
organization and good standing of Borrower, with the original opinion to be signed, dated and delivered to Lender at the date of the Substitution; and



-6-

(n) from time to time before the date of the Substitution, such other documentation or information as
Lender may request in connection with the Substitution, including (i) year-to-date operating statements for each of the Properties and the Substitution Property for the fiscal year in which the date of the Substitution occurs, (ii) operating
statements for each of the Properties and the Substitution Property for the prior fiscal year, (iii) capital and operating budgets for each of the Properties and the Substitution Property for the remainder of the fiscal year in which the date of the
Substitution occurs and for the next succeeding fiscal year, (iv) such other financial information covering operations of each of the Properties and the Substitution Property as required by Lender, and (v) financial statements of Borrower and the
Subsidiaries (to the extent such financial information is then separately prepared).



3.3(f).3. Loan Documents. Borrower shall have executed and delivered to Lender loan documents satisfactory to Lender, in its sole discretion, evidencing and securing the Substitution Property and, as
affected by the Substitution, the Loan and the Obligations, which shall be substantially in the form of the loan documents delivered to Lender from Borrower for the Loan, as modified to address such issues as are particular to the Substitution
Property and/or the Substitution.



3.3(f).4.
Compliance with Laws. The Substitution Property shall comply with all Laws, including those Laws relating to construction, land use, health, safety and environmental matters. All permits, licenses, approvals and franchises required for the
construction, use, operation, occupancy and management of each of the Substitution Property shall have been obtained and be in good standing, and Borrower shall have complied, or caused the Subsidiaries to have complied, with any specific Laws,
conditions or requirements applicable to the Substitution Property.



3.3(f).5. Appraisals. With regard to each of the Substitution Properties, Lender shall have approved, in its sole discretion, current appraisals of each of the Substitution Properties prepared by an appraiser engaged by
Lender. Lender shall provide Borrower with copies of these appraisals provided Borrower executes and delivers a confidentiality and non-reliance letter satisfactory to Lender.



3.3(f).6. Physical Conditions Reports. Lender shall have approved a Physical Conditions Report for the
Substitution Property.



3.3(f).7. Environmental
Reports. Lender shall have approved environmental assessment and compliance reports prepared by an independent expert engaged by Lender for the Substitution Property, complying with Lenders then applicable requirements for comparable
properties, confirming that (i) no Hazardous Substances are present or are suspected to be present, on, in, under, or above the Substitution Property or any surrounding areas; (ii) no release of Hazardous Substances from or onto the Substitution
Property has occurred, is suspected to have occurred, or is threatened; and (iii) the Improvements on the Substitution Property, the manner of construction thereof, and the use and operation thereof (including use and operation by tenants and other
occupants) comply with all Environmental Laws.

consist of one or more tax lots assessed separate and apart from any other property(ies), Borrower shall satisfy Lender,
as determined in its sole discretion, that all Taxes for those tax lots (including the Substitution Property) shall be properly reserved and paid.



3.3(f).9. Bankruptcy. Borrower and all entities comprising the foregoing shall be free from bankruptcy and shall be, as determined by Lender
in its sole discretion, solvent, both in that: (i) the value of their assets shall exceed their liabilities, and (ii) it is reasonable to conclude that each entity shall be able to pay its debts, including, where applicable, payments required by the
Loan Documents, as such become due and payable in the foreseeable future.



3.3(f).10. Legal Matters. Lender shall have approved all legal matters and issues arising as a result of the proposed Substitution.
