RECITALS 

A. TPG/CalSTRS owns indirectly through a series of wholly owned subsidiaries (the “Title Holding Subsidiaries”) that
certain office complex commonly known as City National Plaza, located at 505 – 555 South Flower Street, Los Angeles, California (the “Project”). TPG and CalSTRS are the sole members of TPG/CalSTRS. The current ownership
structure for the Project is shown on Exhibit “B” attached hereto. 
 B. TPGA is a Title Holding Subsidiary
directly and wholly owned by TPG/CalSTRS. 
 C. TPG Plaza Investments is a Title Holding Subsidiary directly and wholly owned by
TPGA. 
 D. In connection with a prior restructure of the ownership of TPG Plaza Investments, TPG Plaza Investments entered into
a financing arrangement with certain of its prior members referred to herein as the Picerne/Kings Capital Loan. 
 E. For
purposes of financing the Project, additional Title Holding Subsidiaries directly and indirectly wholly owned by TPG Plaza Investments obtained the loans identified on Exhibit “C” attached hereto (the “Mezzanine
Loans”), which are currently held by the various holders of the Mezzanine Loans (the “Mezzanine Lenders”). Guarantor guaranteed certain obligations of the borrowers under the Mezzanine Loans pursuant to various guarantees
(the “Loan Guaranties”). 
 F. Also for purposes of financing the Project, another Title Holding Subsidiary
obtained that certain mortgage loan in the principal amount of Three Hundred Fifty Five Million Three Hundred Thousand Dollars ($355,300,000) (the “Mortgage Loan”). 

G. TPG, for itself and on behalf of TPG/CalSTRS and the Title Holding Subsidiaries, after considering the financial status of the Project
and the Mezzanine Loans as well as alternative sources of financing, has specifically requested that CalSTRS acquire the Mezzanine Loans and thereafter retire the Mezzanine Loans in 

 
exchange for an increased equity interest in TPG/CalSTRS relating solely to the Project (the “CNP Additional Interest”). 

H. In connection with the request to acquire the Mezzanine Loans, CalSTRS has formed CNP Investor for the purposes of holding the
Mezzanine Loans while they remain outstanding. Pursuant to the CNP Investor LLC Agreement, CalSTRS is the sole member of CNP Investor, and TPG is the non-member manager thereof with such authority and responsibility as set forth therein. 

I. Upon the Effective Date, CNP Investor entered into a loan purchase agreement with each of the Mezzanine Lenders (the “Loan
Purchase Agreements”), pursuant to which CNP Investor agreed to purchase each Mezzanine Loan from the applicable Mezzanine Lender. Following the acquisition of the Mezzanine Loans, in anticipation of and immediately prior to the
“Conversion” (as defined below), CNP Investor will distribute the Mezzanine Loans to its sole member, CalSTRS, which will retire the Mezzanine Loans and convert the Mezzanine Loans into the CNP Additional Interest, all subject to and in
accordance with the terms hereof. 
 J. Upon the Effective Date, TPG and CalSTRS entered into that certain Sixth Amendment to
Second Amended and Restated Operating Agreement of TPG/CalSTRS, LLC, which is being amended and restated concurrently herewith, in connection with the matters described in this Agreement (the “Sixth Amendment”). TPG and CalSTRS have
also entered into that certain Seventh Amendment to Second Amended and Restated Operating Agreement of TPG/CalSTRS, LLC dated as of May 6, 2010. 

K. To effectuate the Conversion, TPG and CalSTRS intend to enter into that certain Eighth Amendment to Second Amended and Restated
Operating Agreement of TPG/CalSTRS, LLC, in the form attached hereto as Exhibit “D” (the “Eighth Amendment”). 

L. If the acquisition of the Mezzanine Loans and the Conversion were to be consummated as described above, then the ownership structure
for the Project would be as set forth on Exhibit “E” attached hereto. 
 M. The Parties now desire to set forth
herein the terms and conditions pursuant to which CNP Investor will acquire the Mezzanine Loans, following which CalSTRS, as the assignee of the Mezzanine Loans, will convert the Mezzanine Loans into the CNP Additional Interest. 

AGREEMENT 

NOW THEREFORE, in consideration of the mutual promises, covenants and representations hereinafter contained, and subject to the
conditions hereinafter set forth, the parties hereto fully incorporate the Recitals above herein and hereby agree as follows: 

ARTICLE I. 

PURCHASE OF MEZZANINE LOANS 

1.1 Loan Purchase Agreements. CNP Investor, as described above, has entered into the Loan Purchase Agreements with respect to the
Mezzanine Loans. TPG shall use commercially reasonable efforts to facilitate the consummation of the Loan Purchase Agreements, including without limitation, by consulting and coordinating with the Mezzanine Lenders and assisting with the
satisfaction of conditions to closing thereunder. Notwithstanding the foregoing, CNP shall have the right and authority to make all decisions and take all actions under the Loan Purchase Agreements in its sole and absolute discretion. 

1.2 Rights of CNP Investor as Lender. Anything herein to the contrary notwithstanding, during the period prior to the Conversion,
while CNP Investor is the holder of the Mezzanine Loans, Article VII shall apply, and CNP Investor (and CalSTRS as the owner of CNP Investor) shall have all rights and remedies available under the Mezzanine Loan Documents or otherwise, as
more specifically set forth in Article VII. 
 1.3 Mortgage Lender Notification and Consent. Following the
acquisition of all of the Mezzanine Loans in accordance with the Loan Purchase Agreements, CalSTRS, CNP Investor and TPG shall cooperate in 

 
notifying Mortgage Lender that (i) CNP Investor has acquired the Mezzanine Loans using purchase funds consisting of new cash equity funds of CalSTRS which were not derived directly or
indirectly from the Project, and (ii) CNP Investor has waived and relinquished, for the benefit of Mortgage Lender, certain rights of the Mezzanine Lenders under the Intercreditor Agreement. Further, each of CalSTRS, CNP Investor and TPG shall
use commercially reasonable efforts to obtain from Mortgage Lender its written (A) acknowledgment of the foregoing, (B) consent to the retirement of the Mezzanine Loans, without any prepayment of the Mortgage Loan or other material
condition to such consent, and (C) acknowledgment that upon the retirement of the Mezzanine Loans, the Intercreditor Agreement will be terminated as provided therein (collectively, the “Mortgage Lender Consent”). 

1.4 Effect of Closing under Loan Purchase Agreements. The Parties intend that all closings under the Loan Purchase Agreements
shall occur concurrently. Notwithstanding the execution and entry into this Agreement by all Parties on the date hereof, the performance by the Parties of their respective obligations set forth in Articles II, III and V of this Agreement shall
commence to apply only upon the acquisition of the Mezzanine Loans by CNP Investor, if and when such acquisition occurs. Unless and until CNP Investor acquires the Mezzanine Loans, no Party shall have any obligations to any other Party arising under
Articles II, III and V of this Agreement. 
 1.5 No Distributions. Unless agreed by all the members of TPG/CalSTRS in
writing, no distributions shall be made by TPG Plaza Investments from the date hereof until the Mezzanine Loan Acquisition Date. 

ARTICLE II. 

CONVERSION OF LOANS TO EQUITY 

2.1 Agreement to Convert. Following the acquisition of the Mezzanine Loans by CNP Investor, once all of the conditions to the
Conversion provided for herein have been satisfied or waived and as further provided in Section 2.2, CNP Investor shall distribute the Mezzanine Loans to its sole member, CalSTRS, which shall thereafter immediately acquire the CNP Additional
Interest in exchange for CalSTRS entering into the Loan Termination Agreements with each of the Mezzanine Borrowers to terminate all outstanding obligations under the Mezzanine Loans, all in accordance with the terms and conditions set forth below,
thereby converting the Mezzanine Loans into the CNP Additional Interest (the “Conversion”). CalSTRS shall convert all, and not less than all, of the Mezzanine Loans acquired from the Mezzanine Lenders. 

2.2 Timing of Closing of the Conversion. The Conversion shall be scheduled to occur on the date (the “Scheduled Conversion
Date”) that is the earlier of (i) five (5) days following receipt by CalSTRS, CNP Investor and TPG of the Mortgage Lender Consent, (ii) the maturity date of the Mezzanine Loans, or (iii) the date that the Mortgage Loan
has been fully repaid. 
 ARTICLE III. 

CLOSING OF CONVERSION 

3.1 Conversion Closing. Provided that upon the Scheduled Conversion Date (a) all of the conditions to Conversion Closing set
forth in this Agreement have been satisfied or waived by the Party in whose favor the condition runs and (b) this Agreement has not been terminated by any Party in accordance with the provisions set forth herein, the transactions contemplated
hereby shall be consummated (the “Conversion Closing”), with the date that Conversion Closing actually occurs being the “Conversion Date”. 

3.2 CalSTRS’ Closing Deliveries. Upon the Conversion Closing, CalSTRS shall deliver, or cause to be delivered, to TPG:

 3.2.1 Two originals of the Omnibus Assignment (Senior Mezzanine) and the Omnibus Assignment (Junior Mezzanine) in the forms
attached hereto as Exhibit “F”, (collectively, the “Loan Assignments”), duly executed by CNP Investor, as assignor, and CalSTRS, as assignee; 

3.2.2 The original of the note for each Mezzanine Loan marked cancelled by CalSTRS and two originals of the Loan Termination Agreement
(Senior Mezzanine) in the form attached hereto as Exhibit “G”, and 

 
two originals of the Loan Termination Agreement (Junior Mezzanine) in the form attached hereto as Exhibit “H” (collectively, the “Loan Termination Agreements”),
duly executed by CalSTRS; 
 3.2.3 Two originals of the Eighth Amendment, duly executed by CalSTRS; and 

3.2.4 Such other documents and certificates as may be reasonably required by TPG to consummate the Conversion. 

3.3 TPG’s Closing Deliveries. Upon the Conversion Closing, TPG shall deliver, or cause to be delivered, to CalSTRS:

 3.3.1 Two originals of each of the Loan Termination Agreements, duly executed by Junior Mezzanine Borrower and Senior
Mezzanine Borrower, as applicable; 
 3.3.2 Two originals of the Eighth Amendment, duly executed by TPG; and 

3.3.3 Such other documents and certificates as may be reasonably required by CalSTRS to consummate the Conversion. 

3.4 Cash Reconciliation. It had been the intention of the Parties to implement the Conversion concurrently with the Mezzanine Loan
Acquisition Date. However, the Parties recognize that the conditions set forth in Sections 5.1.1 and 5.2.1 will necessitate a delay in the Conversion beyond the Mezzanine Loan Acquisition Date. The Parties desire that, to the maximum
extent possible, the economic effect of a Conversion concurrent with the acquisition of the Mezzanine Loans be replicated notwithstanding such delay. Therefore, upon the Conversion Closing, TPG shall certify in writing as to the financial
information necessary to perform the reconciliation, and the Parties shall in good faith reconcile the differences between the economic results of the Conversion occurring on the Conversion Date as compared to a hypothetical closing on the Mezzanine
Loan Acquisition Date. The Parties shall then calculate an amount of cash that shall be paid by CalSTRS to the Original Interest Holders with respect to the Original Interests, or by the Original Interest Holders to CalSTRS with respect to the CNP
Additional Interest, as applicable based on the net debits and credits for the reconciliation, such that the Conversion on the Conversion Date will result in the same economic effect as if the Conversion had occurred on the Mezzanine Loan
Acquisition Date. This reconciliation shall include, without limitation, the following adjustments: 
 3.4.1 The Original
Interest Holders shall be credited, and CalSTRS shall be debited, with an amount equal to the Original Interest Percentage multiplied by the total debt service payments received by CNP Investor during the Reconciliation Period. 

3.4.2 CalSTRS shall be credited, and the Original Interest Holders shall be debited, with an amount equal to the CNP Additional Interest
Percentage multiplied by the total distributions relating to the City National Plaza Project, if any, by TPG/CalSTRS to the Original Interest Holders during the Reconciliation Period. 

3.4.3 The Original Interest Holders shall be credited, and CalSTRS shall be debited, with an amount equal to the CNP Additional Interest
Percentage multiplied by the total capital contributions relating to the City National Plaza Project, if any, made by the Original Interest Holders to TPG/CalSTRS during the Reconciliation Period. 

Each individual credit to the Original Interest Holders shall be allocated between TPG and CalSTRS as if it were a distribution pursuant to
Section 6.02, as amended from time to time, of the TPG/CalSTRS LLC Agreement. 
 ARTICLE IV.

ARTICLE VII. 

INDEPENDENCE OF RIGHTS 

AS LENDER AND MEMBER. 

7.1 Acknowledgments. TPG for itself and on behalf of the TPG Parties recognizes and acknowledges the following: 

7.1.1 CNP Investor has agreed, and CalSTRS, as the sole member of CNP Investor, has agreed to cause CNP Investor, to acquire the
Mezzanine Loans if CNP Investor, in its capacity as the holder of the Mezzanine Loans, and CalSTRS as its owner, are treated as, and are entitled to all of the rights and remedies of, a third-party lender not in any way related to the TPG Parties.
Were CNP Investor, in its capacity as the Lender, or CalSTRS as the owner of the Lender, to not be treated as, or entitled to all of the rights and remedies of, a third party lender not in any way related to the TPG Parties, CNP Investor would not
have agreed to enter, and CalSTRS would not have agreed to cause CNP Investor to enter, into the Loan Purchase Agreements to purchase the Mezzanine Loans. 

7.1.2 TPG and the other TPG Parties are agreeing to the provisions of this Article VII to induce CNP Investor to acquire, and
CalSTRS to cause CNP Investor to acquire, the Mezzanine Loans. TPG and the other TPG Parties acknowledge that CalSTRS and CNP Investor will be relying upon the provisions of this Article VII in acquiring the Mezzanine Loans and that, but for
this Article VII and the other provisions set forth in this Agreement, CNP Investor would not acquire, and CalSTRS would not cause CNP Investor to acquire, the Mezzanine Loans. The TPG Parties will be benefited by CNP Investor acquiring the
Mezzanine Loans and by the Conversion and that such benefit constitutes actual and adequate consideration for this Agreement. 

 7.1.3 Any provision of this Article VII referencing CNP Investor as Lender shall
extend, whether or not explicitly set forth, to CalSTRS as the owner of CNP Investor. 
 7.1.4 The admission of TPG or any of
its Affiliates as members of CNP Investor shall in no way affect any of the acknowledgments, agreements or waivers made by any of the TPG Parties pursuant to this Article VII. 

7.2 Acquisition of Mortgage Loan. It is the parties’ intention to refinance the Mortgage Loan on or prior to the maturity
date of the Mortgage Loan. Notwithstanding the foregoing and without in any way limiting the provisions of Section 7.1, TPG and the other TPG Parties agree that CalSTRS, CNP Investor and their Affiliates shall be free to acquire the Mortgage
Loan as if it were a third party not in any way related to the TPG Parties, at par, at a discount or on any terms, upon the maturity of the Mortgage Loan (whether scheduled or accelerated). In the event of any acquisition of the Mortgage Loan by
CalSTRS, CNP Investor or any of their Affiliates, the provisions of this Article VII shall apply equally to the Mortgage Loan, with CalSTRS, CNP Investor or such Affiliate as the “CalSTRS Lender” and CalSTRS, CNP Investor or such
Affiliate as a “CalSTRS Member” of a TPG Related Party for purposes of this Article VII. Notwithstanding the foregoing, the Parties hereto agree that CalSTRS, CNP Investor or any applicable Affiliate will convert the Mortgage
Loan into an equity interest in the Project commensurate on a dollar-for-dollar basis with the then-outstanding principal, interest and other payments due under the Mortgage Loan in a manner similar to, and on substantially the same terms as, the
Conversion contemplated herein. 
 7.3 Exercise of Management Control with Respect to Mezzanine Loans. Anything contained
in the TPG/CalSTRS LLC Agreement to the contrary notwithstanding, TPG and CalSTRS agree that the following shall apply with respect to the borrower’s or guarantor’s interest in the Mezzanine Loans, but only during the period that CNP
Investor is the holder of the Mezzanine Loans: 
 7.3.1 TPG shall be designated to act on behalf of TPG/CalSTRS in connection
with all matters related to the Mezzanine Loans. Decisions of TPG/CalSTRS relating to the Mezzanine Loans shall not require any approval of CalSTRS or its representatives. 

7.3.2 The Representatives of CalSTRS to the Management Committee of TPG/CalSTRS shall not be entitled to take any action or exercise any
right or remedy on behalf of TPG/CalSTRS related to the actions of Senior Mezzanine Borrower or Junior Mezzanine Borrower under the Mezzanine Loans, including but not limited to participating in any decisions or actions of TPG/CalSTRS with respect
to the Mezzanine Loans or participating in any Management Committee discussions or decisions that relate to the Mezzanine Loans. 

7.3.3 TPG acting alone shall have the right and authority, on behalf of the TPG Parties, to (i) negotiate and agree to the terms and
provisions of any supplements, modifications or amendments to the Mezzanine Loan Documents; (ii) exercise any rights or remedies, make any elections, give any notices and take any actions authorized or required of any of the TPG Parties under
the Mezzanine Loan Documents; (iii) institute and settle legal proceedings and/or take any other action necessary or appropriate to enforce the rights, exercise the remedies and protect the interests of the TPG Parties under the Mezzanine Loan
Documents; and (iv) make any and all decisions and take any and all actions on behalf of the TPG/CalSTRS in connection with the Mezzanine Loan. 

Nothing in this Section 7.3 shall affect the rights of CNP Investor and CalSTRS as Lender. 

7.4 TPG Party Agreements. TPG, for itself and on behalf of the TPG Parties and their Constituents, agrees that: 

7.4.1 Any CalSTRS Lender’s relationship to any of the TPG Parties and their Constituents as Lender is and shall be treated as
entirely separate and independent from any CalSTRS Member’s relationship to the TPG Parties and their Constituents as a member in a TPG Related Party. 

7.4.2 Any permission, approval, consent, authorization or other such communication by a CalSTRS Lender in its capacity as Lender shall
not be or be deemed to be a permission, approval, consent, 

 
authorization or other such communication by, or to in any way bind, a CalSTRS Member in its capacity as a member in a TPG Related Party. Any permission, approval, consent, authorization or other
such communication by a CalSTRS Member in its capacity as a member in a TPG Related Party, shall not be or be deemed to be a permission, approval, consent, authorization or other such communication by, or to in any way bind, the CalSTRS Lender in
its capacity as Lender. 
 7.4.3 In its capacity as Lender, a CalSTRS Lender (i) shall be entitled to take any action or
exercise any right or remedy, or refrain from taking any action or exercising any right or remedy, permitted hereunder or under any of the Mezzanine Loan Documents, other applicable loan documents, or applicable Laws as if the CalSTRS Lender were an
independent third party with no relationship to the TPG Parties or their Constituents other than the Mezzanine Loans or such other applicable loans, and (ii) shall not be subject to, and the TPG Parties’ and their Constituents’
obligations to a CalSTRS Lender in its capacity as Lender shall not be limited, excused by or subject to, any defenses, offsets, counterclaims or other remedies of any nature which the TPG Parties or their Constituents might have against a CalSTRS
Member in its capacity as a member in a TPG Related Party. 
 7.4.4 In its capacity as a member in a TPG Related Party, a
CalSTRS Member (i) shall be entitled to take any action or exercise any right or remedy, or refrain from taking any action or exercising any right or remedy, permitted hereunder or under the applicable operating agreement of the TPG Related
Party, or applicable Laws as if the CalSTRS Lender were not the Lender, and (ii) shall not be subject to, and the TPG Parties’ and their Constituents’ obligations to the CalSTRS Member in its capacity as a member in a TPG Related
Party shall not be limited, excused by or subject to, any defenses, offsets, counterclaims or other remedies of any nature which any of the TPG Parties or their Constituents might have against the CalSTRS Lender in its capacity as Lender.

 7.4.5 Each of the TPG Parties and each of their respective Constituents unconditionally and irrevocably waives any right or
power to withhold, delay or otherwise limit in any way the performance of any of the duties, obligations and liabilities of such TPG Party and its Constituents (i) to any CalSTRS Lender in its capacity as Lender, notwithstanding any defenses,
offsets, counterclaims or other remedies of any nature which any of the TPG Parties or their Constituents might have against the CalSTRS Member in its capacity as a member in a TPG Related Party; and (ii) to a CalSTRS Member in its capacity as
a member in a TPG Related Party, notwithstanding any defenses, offsets, counterclaims or other remedies of any nature which any TPG Party or its Constituents might have against a CalSTRS Lender in its capacity as the Lender. 

7.4.6 None of the rights, remedies, benefits or protections in favor of, and none of the duties, obligations or liabilities of any of the
TPG Parties or their Constituents to, (i) a CalSTRS Lender in its capacity as the Lender shall be diminished, impaired or affected in any way by virtue of a CalSTRS Member being a member in a TPG Related Party; or (ii) a CalSTRS Member in
its capacity as a member in a TPG Related Party shall be diminished, impaired or affected in any way by virtue of a CalSTRS Lender being the Lender. 

7.4.7 Any duties, liabilities or obligations (including without limitation fiduciary duties, liabilities or obligations) owed by a
CalSTRS Member, in its capacity as a member in a TPG Related Party, to any TPG Party or its Constituents shall not extend or apply in any way to the separate and independent relationship of any CalSTRS Lender to the TPG Parties and their
Constituents in its capacity as the Lender, and any duties, liabilities or obligations (including without limitation fiduciary duties, liabilities or obligations) owed by a CalSTRS Lender in its capacity as Lender, to any of the TPG Parties or their
Constituents shall not extend or apply in any way to the separate and independent relationship to any of the TPG Parties and their Constituents of any CalSTRS Member in its capacity as a member in a TPG Related Party. Any such duties, liabilities or
obligations (including without limitation fiduciary duties, liabilities or obligations), to the extent they would so extend or apply, are hereby knowingly and intentionally waived and released. 

7.4.8 No CalSTRS Member, in its capacity as a member in a TPG Related Party, has, nor shall be deemed to have, any duties, liabilities or
obligations (including without limitation fiduciary duties, liabilities or obligations) to any of the TPG Parties or their Constituents to the extent that any such duty, liability or obligation (including without limitation fiduciary duties,
liabilities or obligations) shall be based on or derived from a CalSTRS Lender being the Lender. No CalSTRS Lender, in its capacity as Lender, has, nor shall be deemed to have, any duties, liabilities or obligations (including without limitation
fiduciary duties, liabilities or obligations) to any of the TPG Parties or their Constituents to the extent that any such duty, liability or obligation (including without 

 
limitation fiduciary duties, liabilities or obligations) shall be based or derives from any CalSTRS Member being a member in a TPG Related Party. 

7.4.9 Neither the provisions of this Article VII nor anything contained herein shall create, result in or be an admission or
evidence of, or be deemed to create, result in or be an admission or evidence of, any duty, obligation or liability (including without limitation fiduciary duties, obligations or liabilities) on the part of any CalSTRS Member, in its capacity as a
member in a TPG Related Party, or any CalSTRS Lender, in its capacity as Lender, that does not or would not exist in the absence of this Article VII. 

7.5 Release and Waiver. In connection with this Agreement, each of the TPG Parties acknowledges and agrees on its own behalf, and
on behalf of its Constituents, that the TPG Parties and their respective Constituents have waived and released certain rights, defenses and remedies that might otherwise have been available to the TPG Parties or their Constituents. The releases,
waivers and other provisions of this Article VII shall be effective with respect to all matters, past and present, known and unknown, suspected and unsuspected, notwithstanding that factual matters now unknown or unknowable may have given or
may hereafter give rise to losses, damages, liabilities, costs and expenses which are presently unknown, unanticipated and unsuspected. The waivers, releases and other provisions of this Article VII, including without limitation the following
waiver of the provisions of California Civil Code Section 1542, have been expressly bargained for, negotiated and agreed upon in light of the foregoing. In furtherance of this intention, TPG, TPG Plaza Investments, each of the TPG Parties, on
behalf of themselves and their Constituents, hereby expressly waive any and all rights and benefits conferred upon it or them by the provisions of California Civil Code Section 1542, which provides as follows: 

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.”

 8.8 Governing Law; Jurisdiction; Litigation. This Agreement has been
prepared, executed and delivered in, and shall be interpreted under, the internal laws of the State of California, without giving effect to its conflict of law provisions. Each of the parties hereto irrevocably and unconditionally waives any

documents to be executed by CalSTRS shall be agreed to and prepared in final execution form and received by CalSTRS to allow for compliance with the foregoing schedule. In the event any of the foregoing conditions are not complied with in accordance
with the foregoing schedule, the Scheduled Conversion Date shall be automatically extended by the number of days necessary to allow CalSTRS the time periods set forth above for the execution and delivery of documents and the transfer of funds.

 8.18 CalSTRS Counsel. 

8.18.1 The parties acknowledge and agree that Cox, Castle & Nicholson LLP (“CalSTRS Counsel”) has represented
and will represent only CalSTRS and CNP Investor in connection with this Agreement, the acquisition and ownership of the Mezzanine Loans by CNP Investor, the Conversion and the Conversion 

 
Documents (the “CalSTRS Matters”). As part of the CalSTRS Matters, CalSTRS Counsel will represent CalSTRS in its capacity as the owner of CNP Investor in connection with the
acquisition of the Mezzanine Loans and the enforcement of the Lender’s rights and remedies under the Mezzanine Loan Documents, including without limitation, if necessary, the appointment of a receiver and foreclosure. CalSTRS Counsel does not
and will not represent any of the TPG Parties or any of their Constituents in connection with the CalSTRS Matters. Further, no attorney/client, trust, confidential or other special relationship exists or will exist between CalSTRS Counsel, on one
hand, and the TPG Parties or any of their Constituents, on the other hand, in connection with the CalSTRS Matters, and CalSTRS Counsel shall have no duties to the TPG Parties or any of their Constituents in connection with the CalSTRS Matters.

 8.18.2 The parties further acknowledge and agree that one or more of the TPG Parties may have in the past, and may in the
future, engage CalSTRS Counsel for advice or representation on matters not related to the CalSTRS Matters including, without limitation, matters related to the ownership, operation and financing of the Project with unrelated parties (the
“Venture Matters”). CalSTRS Counsel’s sole client in the Venture Matters will be the applicable TPG Party. Each of the TPG Parties, on its own behalf and on behalf of its Constituents consents to CalSTRS Counsel’s
representation of any of the TPG Parties and acknowledges and agrees that, in the Venture Matters, CalSTRS Counsel is not representing any party other than the applicable TPG Party. Thus, no lawyer-client, trust, confidential or other special
relationship will exist between CalSTRS Counsel and any such party other than the applicable TPG Party in connection with the Venture Matters. Nothing in this Section 8.18 shall prohibit CalSTRS Counsel from representing TPG/CalSTRS and
the Title Holding Subsidiaries with respect to the ownership and operation of the Project and, with the sole exception of the Mezzanine Loans during the period when CNP Investor owns the Mezzanine Loans, its financing. 

8.18.3 CalSTRS and the TPG Parties, each on its own behalf and on behalf of its Constituents, agree that CalSTRS Counsel may concurrently
represent CalSTRS in its capacity as the holder of the Mezzanine Loans in connection with the CalSTRS Matters and TPG/CalSTRS in connection with Venture Matters. CalSTRS and the TPG Parties, each on its own behalf and on behalf of its Constituents,
waives and releases any conflicts arising out of that concurrent representation. 
 8.18.4 Further, the parties intend that
CalSTRS Counsel shall remain free to represent CalSTRS or its affiliates on any issue or matter, including any dispute that is or may be adverse to the interests of the TPG Parties. Therefore, each of the TPG Parties, on its own behalf and on behalf
of its Constituents, agrees that if a future dispute were to arise between CalSTRS, on the one hand, and any one or more of the TPG Parties, on the other hand, CalSTRS Counsel may represent CalSTRS in such dispute, whether or not related to the
Venture Matters. CalSTRS Counsel is also authorized to share with CalSTRS any and all information related to the Venture Matters. Further, CalSTRS Counsel may withdraw from representation of any TPG Party for any reason and may continue to represent
CalSTRS on any matter, including any matter that is adverse to a TPG Party, even if it is related to the matter with respect to which CalSTRS Counsel has withdrawn from representing a TPG Party. 

8.18.5 Each of the TPG Parties, on its own behalf and on behalf of its Constituents, waives and releases any conflicts arising out of
CalSTRS Counsel’s representation of any TPG Party in connection with Venture Matters. The TPG Parties, each on its own behalf and on behalf of its Constituents, covenants and agrees, that in no event may any of the TPG Parties any of their
Constituents seek to disqualify CalSTRS Counsel from any matter on the grounds of CalSTRS Counsel’s representation of a TPG Party in connection with Venture Matters. By way of example, in the event any dispute or controversy arises between
TPG/CalSTRS, on the one hand, and CalSTRS, on the other hand, then CalSTRS Counsel may represent CalSTRS in any such dispute or controversy. 

8.18.6 This Section 8.18 shall survive the consummation of the transactions contemplated hereby or the termination hereof, whether
or not any of the transactions have been consummated.
