duty to supervise or inspect the construction or examine any books and records. Any inspection or examination by Lender is for the sole purpose of protecting Lenders security and preserving Lenders rights under this Agreement. No default
of Borrower will be waived by any inspection by Lender. In no event will any inspection by Lender be a representation that there has been or will be compliance with the Plans and Specifications or that the construction is free from defective
materials or workmanship.

Section 7.5          Limitation of Responsibility. The making of any Advance by Lender shall not constitute or be interpreted as either (A) an approval or acceptance
by Lender of the work done through the date of the Advance, or (B) a representation or indemnity by Lender

to any party against any deficiency or defect in the work or against any breach of any contract. Inspections and approvals of the Plans and Specifications, the Tenant Improvements or Capital
Expenditures, as applicable, the workmanship and materials used in the Tenant Improvements or Capital Expenditures, as applicable, and the exercise of any other right of inspection, approval, or inquiry granted to Lender in this Agreement are
acknowledged to be solely for the protection of Lenders interests, and under no circumstances shall they be construed to impose any responsibility or liability of any nature whatsoever on Lender to any party. Neither Borrower nor any
contractor, subcontractor, materialman, laborer, or any other person shall rely, or have any right to rely, upon Lenders determination of the appropriateness of any Advance. No disbursement or approval by Lender shall constitute a
representation by Lender as to the nature of the Project, its construction, or its intended use for Borrower or for any other person, nor shall it constitute an indemnity by Lender to Borrower or to any other person against any deficiency or defects
in the Project or against any breach of any contract.

Section 7.6          Cessation of Advances. Lender shall have no obligation to make Advances or to disburse Loan proceeds under this Agreement or under any other Loan
Documents upon the occurrence of any Event of Default.

ARTICLE 8

DEFAULT

Any failure by Borrower or any Guarantor to perform, observe or comply with any of the terms, conditions, agreements, covenants or provisions of this Agreement (including, but not limited to, failure to
construct the Tenant Improvements or Capital Expenditures, as applicable, in accordance with the Project Documents) or any other Loan Documents, shall constitute an Event of Default hereunder.

ARTICLE 9

REMEDIES

Upon the occurrence of any Event of Default and at any time thereafter, Lender may,
at its option, but without any obligation to do so, and in addition to any other right Lender without notice to Borrower may have, exercise any or all of the following rights, remedies and recourses, without notice to Borrower:

a.  institute appropriate proceedings to enforce the performance of this Agreement;

b.  withhold further disbursement of the Loan Fund;

c.  expend funds necessary to remedy the Event of Default;

d.  take possession of the Mortgaged Property and continue construction of the Project;

e.  exercise any other right or remedy which it has under the Note or Loan Documents, or which is otherwise
available at law or in equity or by statute;



LOAN AGREEMENT - 13



---

f.        setoff against and/or use
the funds in the Account (or any portion thereof) for any purpose, including, without limitation (i) payment of any Indebtedness secured by the Note, any other Loan Documents and this Agreement, including, without limitation, principal
prepayments and the prepayment premium applicable to such prepayment (as applicable); (ii) reimbursement of Lender for all losses and expenses (including, without limitation, reasonable legal fees and disbursements) suffered or incurred by
Lender as a result of such default; or (iii) payment of any amount expended in exercising all rights and remedies available to Lender at law or in equity or under this Agreement or under the Loan Documents.

Borrower consents to such actions by Lender without any further instructions or consents from Borrower. Borrower consents to, authorizes,
and directs Lender to comply with any entitlement orders within the meaning of Section 8-102(h) of the Uniform Commercial Code (the UCC) regarding any funds held in the Account, without any further action
or consent by Borrower. Provided, however, that a setoff by Lender or use of any funds in the Account by Lender shall not, under any circumstances, be deemed a cure of an Event of Default, and, after the occurrence of an Event of
Default and a setoff by Lender or use of the funds in the Account by Lender, Borrower shall continue to be in default and Lender shall be entitled to exercise all rights and remedies available to Lender upon the occurrence of such Event of Default.
Nothing in this Agreement or the other Loan Documents shall obligate Lender to apply all or any portion of the funds in the Account on account of any default by Borrower or to repayment of the Indebtedness secured by the Loan Documents or in any
specific order of priority.

ARTICLE 10

COMPLETION OF IMPROVEMENTS BY LENDER

If Lender takes possession of the Mortgaged Property, it may take any and all actions necessary in its judgment to complete construction of the Tenant Improvements or Capital Expenditures, as applicable, including, but not limited to,
making changes in the Plans and Specifications, work, or materials and entering into, modifying or terminating any Project Documents, subject to Lenders right at any time to discontinue any work without liability. If Lender elects to complete
the Tenant Improvements or Capital Expenditures, as applicable, it will not assume any liability to Borrower or to any other Person for completing the Tenant Improvements or Capital Expenditures, as applicable, or for the manner or quality of
construction of the Tenant Improvements or Capital Expenditures, as applicable, and Borrower expressly waives any such liability. Borrower irrevocably appoints Lender as its attorney-in-fact, with full power of substitution, to complete the Tenant
Improvements or Capital Expenditures, as applicable, at Lenders option, either in Borrowers name or in its own name. In any event, all sums expended by Lender in completing construction of the Tenant Improvements or Capital Expenditures,
as applicable, will be considered to have been disbursed to Borrower and will be secured by the Mortgaged Property. Any such sums that cause the principal amount of the Loan to exceed the face amount of the Note will be considered to be an
additional Loan to Borrower, bearing interest at the rate set forth in the Note and being secured by the Mortgaged Property. For these purposes, Borrower assigns to Lender all of its right, title and interest in and to the Project Documents;
provided, however, Lender will not have any obligation under the Project Documents unless Lender expressly hereafter agrees in writing to assume such obligations. Upon the occurrence of an Event of Default, Lender will have the right
to exercise any rights of Borrower under the Project Documents. Except as may be prohibited by



LOAN AGREEMENT - 14

applicable law, all of Lenders rights and remedies, whether evidenced by this Agreement or by any other writing, shall be cumulative and may be exercised singularly or concurrently.

ARTICLE 11

Section 11.2        Attorneys Fees; Expenses. Borrower
agrees to pay upon demand all of Lenders reasonable costs and expenses, including Lenders attorneys fees and legal expenses, incurred in connection with the enforcement of this Agreement. Lender may hire or pay someone else to help
enforce this Agreement, and Borrower shall pay the reasonable costs and expenses (i) in connection with each Advance and (ii) with any enforcement of this Agreement. Costs and expenses include Lenders attorneys fees and legal
expenses whether or not there is a lawsuit, including attorneys fees and legal expenses for bankruptcy proceedings (including efforts to modify or vacate any automatic stay or injunction), appeals, and any anticipated post-judgment collection
services. Borrower also shall pay all court costs and such additional fees as may be directed by the court.

Section 11.3        Authority to File Notices. Borrower appoints and designates Lender as its attorney-in-fact to file for record any notice that Lender deems necessary to protect
its interest under this Agreement. This power shall be deemed coupled with an interest and shall be irrevocable while any sum or performance remains due and owing under any of the Loan Documents.

interpretation of this Agreement and the Loan Documents (without giving effect to principles of conflicts of law), except to the extent otherwise specified in this Agreement or any of the Loan Documents.

Section 11.6        No Waiver by Lender. Lender shall not be
deemed to have waived any rights under this Agreement unless such waiver is given in writing and signed by Lender. No delay or omission on the part of Lender in exercising any right shall operate as a waiver of such right or any other right. A
waiver by Lender of a provision of this Agreement shall not prejudice or constitute a waiver of Lenders right otherwise to demand strict compliance with



LOAN AGREEMENT - 15



---

that provision or any other provision of this Agreement. No prior waiver by Lender, nor any course of dealing between Lender and Borrower, shall constitute a waiver of any of Lenders rights
or of any of Borrowers obligations as to any future transactions. Whenever the consent of Lender is required under this Agreement, the granting of such consent by Lender in any instance shall not constitute continuing consent to subsequent
instances where such consent is required and in all cases such consent may be granted or withheld in the sole discretion of Lender.

Section 11.7        Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable, such provision shall be
fully severable; the Agreement shall be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part thereof; the remaining provisions thereof shall remain in full effect and shall not be affected by the
illegal, invalid or unenforceable provision or by its severance therefrom; and in lieu of such illegal, invalid or unenforceable provision, there shall be added automatically as a part of the Agreement a provision as similar in terms to such
illegal, invalid or unenforceable provision as may be possible to be legal, valid and enforceable.

Section 11.8        Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of Lender and Borrower and their respective successors and assigns.

AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, STATEMENT (WHETHER

CANCEL THE NOTE, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, AND ANY CLAIM OR DEFENSE ASSERTING THAT THE NOTE, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT WAS FRAUDULENTLY INDUCED OR IS OTHERWISE VOID OR VOIDABLE). THIS WAIVER IS A MATERIAL INDUCEMENT
FOR LENDER TO ENTER INTO THE NOTE, THIS AGREEMENT AND THE LOAN DOCUMENTS.
