persons and parties whomsoever.

SECTION 1.02.Intentionally Deleted.

SECTION 1.03.Intentionally Deleted.

SECTION 1.04.Intentionally Deleted.

SECTION 1.05.All right, title and interest of Trustor in and to all extensions, improvements, betterments, renewals,
substitutes and replacements of, and all additions and appurtenances to, the Mortgaged Property, hereafter acquired by, or released to, or constructed, assembled or placed by Trustor on the Premises,
and all conversions of the security constituted thereby, immediately upon such acquisition, release, construction, assembling, placement or conversion, as the case may be, and in each such case,
without any further grant, conveyance, assignment or other act by Trustor, shall become subject to the first and prior lien and security interest of this Deed of Trust as fully and completely, and
with the same effect, as though now owned by Trustor and specifically described in the granting clause hereof.

SECTION 1.06.Trustor will pay from time to time when the same shall become due, all lawful claims and demands for
payment made by mechanics, materialmen, laborers, and others which, if unpaid, might result in, or permit the creation of, a lien on the Mortgaged Property or any part thereof, or on the revenues,
rents, issues, income and profits arising therefrom and in general will do or cause to be done everything necessary so that the lien and security interest hereof shall be fully preserved, at the cost
of Trustor, without expense to Beneficiary.

SECTION 1.07.In the event of the passage, after the date of this Deed of Trust, of any law of the State of California
deducting from the value of the Mortgaged Property for the purpose of taxing the amount of any lien thereon, or changing in any way the laws now in force for the taxation of deeds of trust, or debts
secured thereby, for state or local purposes, or the manner of operation of any such taxes so as to adversely affect the interest of Beneficiary, then and in such event, Trustor shall bear and pay the
full amount of such taxes, provided that if for any reason payment by Trustor of any such new or additional taxes would be unlawful or if the payment thereof would constitute usury or render the
Notes, the Credit Agreement or the indebtedness secured hereby wholly or partially usurious under any of the terms or provisions of the Notes, the Credit Agreement, or this Deed of Trust, or
otherwise, Beneficiary may, at its option, upon thirty (30) days' written notice to Trustor, pay that amount or portion of such taxes as renders the Notes, the Credit Agreement, or the
indebtedness secured hereby unlawful or usurious, in which event Trustor shall concurrently therewith pay the remaining lawful non-usurious portion or balance of said taxes.

SECTION 1.08.Except to the extent permitted under the Credit Agreement, Trustor will not further encumber, sell,
convey or transfer any interest in, or any part of, the Mortgaged Property, without the prior written consent of Beneficiary.

SECTION 1.09.Notwithstanding Section 1.08 to the contrary, Trustor shall have the right to enter into leases of
the Premises provided such leases are subordinate to this Deed of Trust.

SECTION 1.10.Trustor shall comply (so that such compliance will not cause a Material Adverse Effect on the Mortgaged
Property) with all applicable restrictive covenants, zoning and subdivision ordinances and building codes, all health and environmental laws and regulations and all other applicable laws, rules,
regulations, requirements, directions, orders and notices of violations issued by any governmental agency, body or officer relating to or affecting the Premises or the business or activity being
conducted thereon whether by Trustor or by any occupant thereof.

SECTION 1.11.If Trustor shall fail to perform any of the covenants contained herein on its part to be performed, and
if such failure shall continue for more than thirty (30) days after written notice to Trustor (or if such failure cannot reasonably be cured within thirty (30) days, such longer time as
is reasonably needed to effect such cure, provided Trustor is diligently attempting to effectuate such cure), Beneficiary may, but shall not be required to, make advances to perform the same, or cause
the same to be performed, on Trustor's behalf, and all sums so advanced shall bear interest, from and after the date advanced until repaid, at the lower of (i) the maximum rate permitted by law
or (ii) the default rate set forth in the Credit Agreement, shall be a lien upon the Mortgaged Property and shall,

4

---

at Beneficiary's option, be added to the indebtedness secured hereby. Trustor will repay within two (2) Business Days after written request by Beneficiary, all sums so advanced on its behalf
with interest
at the rate herein set forth. This Section 1.11 shall not be construed as preventing any failure by Trustor in the observance of any covenant contained in this Deed of Trust from constituting
an Event of Default hereunder.

SECTION 1.12.Trustor will not commit any waste at or with respect to the Mortgaged Property nor will Trustor do or
fail to do anything which will in any way materially increase the risk of fire or other hazard to the Premises, Improvements or Chattels or to any part thereof.

SECTION 1.13.Trustor will immediately notify Beneficiary of the institution of any proceeding for the condemnation or
taking by eminent domain of the Mortgaged Property, or any portion thereof. The Trustee and Beneficiary may participate in any such proceeding and Trustor from time to time will deliver to Beneficiary
all instruments requested by it to permit such participation. In the event of such condemnation proceedings, or a conveyance in lieu of such taking, subject to the terms and conditions below, the
award or compensation payable shall be paid to Beneficiary and thereafter disbursed and applied in accordance with Section 7.6(ii) of the Credit Agreement. Beneficiary shall be under no
obligation to question the amount of any such award or compensation and may accept the same in the amount in which the same shall be paid, but shall have no right to bind Trustor or to make settlement
of Trustor's claim. In any such condemnation proceedings the Trustee and Beneficiary may be represented by counsel selected by Beneficiary. Notwithstanding the foregoing or provisions of the Credit
Agreement to the contrary, in the event of any proceeding for the condemnation or taking by eminent domain (or any sale in lieu thereof) of any portion of the Mortgaged Property having a value of less
than One Million Dollars ($1,000,000), Trustor shall have the sole and exclusive right to control the contest or settlement of such proceedings or claim related thereto. In such event, the entire
amount of the proceeds or any taking or sale in lieu thereof shall be paid to Trustor. Furthermore, notwithstanding the foregoing, the proceeds of any taking or sale in lieu thereof shall first be
made available to Trustor to fund restoration of the remaining portion of the Mortgaged Property, but only to the extent that Beneficiary shall receive a first perfected security interest in any such
additional items acquired by Trustor, before any proceeds are applied to the repayment of the Note or other Secured Obligations.

SECTION 1.14.In accordance with Section 2938 of the California Civil Code, the assignment of rents, income and
other benefits (collectively, "rents") contained in the granting clause of this Deed of Trust shall be fully operative without any further action on the part of Trustor or Beneficiary and specifically
Beneficiary shall be entitled, at its option, to all rents from the Mortgaged Property whether or not Beneficiary takes possession of the Mortgaged Property. Trustor shall at all times direct that all
rents from the Mortgaged Property be deposited in the Payment Account established at the Clearing Bank pursuant to a Blocked Account Agreement, and the disposition of such rents governed accordingly.
Upon the occurrence and during the continuance of an Event of Default, Trustor hereby further grants to Beneficiary the right (i) to dispossess by the usual summary proceedings any tenant
defaulting in the payment thereof to Beneficiary, (ii) to let the Mortgaged Property or any part thereof, and (iii) to apply the rents, after payment of all necessary charges and
expenses, on account of the indebtedness and other sums secured hereby. Such assignment and grant shall continue in effect until the indebtedness and other sums secured hereby are paid, the execution
of this Deed of Trust constituting and evidencing the irrevocable consent of Trustor to the entry upon and taking possession of the Mortgaged Property by Beneficiary pursuant to such grant, whether or
not sale or foreclosure has been instituted. Neither the exercise of any rights under this Section by Beneficiary nor the application of the rents to the indebtedness and other sums secured hereby,
shall cure or waive any Event of Default, or notice of
default hereunder or invalidate any act done pursuant hereto, but shall be cumulative of all other rights and remedies.

5

---

In accordance with Section 2938 of the California Civil Code, the foregoing provisions hereof shall constitute an absolute and present assignment of the rents from the
Mortgaged Property, subject, however, to the conditional permission given to Trustor to collect and use the rents until the occurrence of an Event of Default at which time such conditional permission
shall automatically terminate; and the existence or exercise of such right of Trustor shall not operate to subordinate this assignment, in whole or in part, to any subsequent assignment by Trustor
permitted under the provisions of this Deed of Trust, and any such subsequent assignment by Trustor shall be subject to the rights of the Trustee and Beneficiary hereunder.

SECTION 1.15.(a) Trustor will not (i) execute an assignment of the rents or any part thereof from the
Mortgaged Property unless such assignment shall provide that it is subject and subordinate to the assignment contained in this Deed of Trust, and any additional or subsequent assignment executed
pursuant hereto, or (ii) except where the lessee is in default thereunder, terminate or consent to the cancellation or surrender of any lease of the Mortgaged Property (where annual gross rent
equals or exceeds $500,000) or of any part thereof, now existing or hereafter to be made or (iii) modify any such lease (where annual gross rent equals or exceeds $500,000) or give consent to
any assignment or subletting without Beneficiary's prior written consent, or (iv) accept prepayments of any installments of rent or additional rent to become due under such leases (where annual
gross rent equals or exceeds $500,000), except prepayments for a period less than thirty (30) days in advance of the date when due or prepayments in the nature of security for the performance
of the lessee's obligations thereunder, or (v) in any other manner materially impair the value of the Mortgaged Property or the security of the Trustee or Beneficiary for the payment of the
indebtedness secured hereby.



SECTION 1.16.Each lease of the Mortgaged Property or of any part thereof entered into after the date hereof shall
provide that, in the event of the enforcement by the Trustee or Beneficiary of the remedies provided for by law or by this Deed of Trust, any person succeeding to the interest of Trustor as a result
of such enforcement shall not be bound by any payment of rent or additional rent for more than one (1) month in advance, provided, however, that nothing herein set forth shall affect or impair
the rights of Beneficiary to terminate any one or more of such leases in connection with the exercise of its or the Trustee's remedies hereunder.

SECTION 1.17.Intentionally Deleted.

ARTICLE II  EVENTS OF DEFAULT AND REMEDIES

SECTION 2.01.An "Event of Default" under the Credit Agreement shall constitute an event of default ("Event of
Default") hereunder. As used herein, the term "event of default" or "default", as the context so indicates, means an Event of Default as defined in the immediately preceding sentence of this
Section 2.01.

Upon
the occurrence of an Event of Default, and in every such case:

I.
During the continuance of any Event of Default, Beneficiary personally, or by its agents or attorneys may enter into and upon all or any part of the Mortgaged Property, and each
and every part thereof, and may exclude the party owning the beneficial interest in same, its agents and servants wholly therefrom; and having and holding the same, may use, operate, manage and
control the Mortgaged Property for any lawful purpose and conduct the business thereof, either personally or by its superintendents, managers, agents, servants, attorneys or receivers; and upon every
such entry, Beneficiary, at the expense of Trustor, from time to time, either by purchase, repairs or construction, may maintain and restore the Mortgaged Property, whereof it shall become possessed
as aforesaid, may complete the construction of any portion of the Improvements and in the course of such completion may make such reasonable changes in the contemplated Improvements as it may deem
necessary; may insure or reinsure the same as provided in the Credit Agreement, and likewise, from time to time, at the expense of Trustor, Beneficiary may make all necessary or proper repairs,
renewals, replacements, and alterations, to the Mortgaged Property or any part thereof and thereon as it may deem advisable; and in every such case Beneficiary shall have the right to manage and
operate the Mortgaged Property, possessed as aforesaid, and to carry on the business thereof and exercise all rights and powers of the party owning such property with respect thereto either in the
name of such party or otherwise as it shall deem best; and Beneficiary shall be entitled to collect and receive all earnings, revenues, rents, issues, profits and income of the Mortgaged Property and
every part thereof; and after deducting the expenses of conducting the business thereof and of all maintenance, repairs, replacements, alterations, additions, betterments and improvements and all
payments which may be made for taxes, assessments, insurance, in payment of any prior deed of trust and prior or other proper charges upon the Mortgaged Property or any part thereof, as well as just
and reasonable compensation of Beneficiary for the services of Beneficiary and for all attorneys, counsel, agents, clerks, servants and other employees by it properly engaged and employed, Beneficiary
shall apply the moneys arising as aforesaid in accordance with Section 3.8 of the Credit Agreement.

II.
Beneficiary, at its option, may declare the entire unpaid balance of the indebtedness secured hereby immediately due and payable by delivery to Trustee of written declaration of
default and demand for sale and written notice of default and of election to cause the Mortgaged Property to be sold, which notice Trustee shall cause to be duly filed for record. Beneficiary shall
also deposit with the Trustee this Deed of Trust, the Notes and all documents evidencing the expenditures secured hereby.

III.
After the lapse of such time as may then be required by law following the recordation of said notice of default, and notice of sale having been given as then required by law,
Trustee, without demand on Trustor, shall sell the Mortgaged Property at the time and place fixed by it in said notice of sale, either as a whole or in separate parcels, and in such order as it may
determine, at public auction to the highest bidder for cash in lawful money of the United States, payable at time of sale. If the Mortgaged Property consists of several known lots or parcels,
Beneficiary may designate the order in which such parcels shall be sold or offered for sale. Any person, including Trustor, Trustee or Beneficiary, may purchase at such sale.

IV.
Trustee may postpone sale of all or any portion of the Mortgaged Property by public announcement at such time and place of sale, and from time to time thereafter may postpone such
sale by public announcement at the time fixed by the preceding postponement.

7

---

V. On and after the occurrence of an Event of Default, Trustor shall pay all rents, issues and profits thereafter received by Trustor from the Mortgaged Property to Beneficiary and to
the extent not paid shall hold such amounts as trust funds for the benefit of Beneficiary and such rents, issues and profits shall be deemed "cash collateral" of Beneficiary under 11 U.S.C., as
amended.

SECTION 2.02.(a) Trustee, after making such sale, and upon receipt of the purchase price, shall make, execute
and deliver to the purchaser or purchasers its deed or deeds conveying the Mortgaged Property so sold, but without any covenant or warranty, express or implied, and without any representation, express
or implied, as to the existence, or lack thereof, of Hazardous Substances on the Mortgaged Property, and shall apply the proceeds of sale thereof to payment in accordance with Section 3.8 of
the Credit Agreement.



SECTION 2.03.After the happening of an Event of Default by Trustor under this Deed of Trust and immediately upon the
commencement of any action, suit or other legal proceeding by Beneficiary to obtain judgment for the principal of, or interest on, the Notes or due pursuant to the Credit Agreement and other sums
required to be paid by Trustor pursuant to any provisions of this Deed of Trust, or of any other nature in aid of the enforcement of the Notes, the Credit Agreement, or of this Deed of Trust, Trustor
will waive the issuance and service of process and enter its voluntary appearance in such action, suit or proceeding. Further, Trustor hereby consents to the appointment of a receiver or receivers of
the Mortgaged Property and of all the earnings, revenues, rents, issues, profits and income thereof. After the happening of any such Event of Default and during its continuance or upon the
commencement of any proceedings to foreclose this Deed of Trust or to enforce the specific performance hereof or in aid thereof or upon the commencement of any other judicial proceeding to enforce any
right of the Trustee or Beneficiary hereunder, Beneficiary shall be entitled, as a matter of right, if it shall so elect, without the giving of notice to any other party and without regard to the
adequacy or inadequacy of any security for the Deed of Trust indebtedness, forthwith either before or after declaring all sums evidenced by the Notes or due pursuant to the Credit Agreement to be due
and payable, to the appointment of such a receiver or receivers.

SECTION 2.04.During the continuance of an Event of Default, Beneficiary shall have the following rights and remedies:



8

---



9

---



SECTION 2.05.No remedy herein conferred upon or reserved to the Trustee or Beneficiary is intended to be exclusive of
any other available remedy or remedies, but each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in
equity or by statute. No delay or omission of the Trustee or Beneficiary to exercise any right or power occurring upon the Event of Default shall impair any such right or power or shall be construed
to be a waiver thereof or an acquiescence therein; and every power and remedy given by this Deed of Trust to the Trustee or Beneficiary may be exercised from time to time and as often as may be deemed
expedient by the Trustee or Beneficiary. Nothing in this Deed of Trust or in the Notes or Credit Agreement shall affect the obligation of Trustor to pay the principal and interest on the Notes and all
sums due under the Credit Agreement in the manner and at the time and place therein respectively expressed.

SECTION 2.06.To the extent permitted by law, Trustor will not at any time insist upon, or plead, or in any manner
whatever claim or take any benefit or advantage of, any stay or extension or moratorium law, any exemption from execution or sale of the Mortgaged Property or any part thereof, wherever enacted, now
or at any time hereafter in force, which may affect the covenants and terms of performance of this Deed of Trust; nor claim, take or insist upon any benefit or advantage of any law now or hereafter in
force providing for the marshalling of the Mortgaged Property, or any part thereof, prior or subsequent to any sale or sales thereof which may be made pursuant to any provision herein, or pursuant to
the decree, judgment or order of any court of competent jurisdiction; and Trustor hereby expressly waives all benefit or advantage of any such law or laws, and covenants not to hinder, delay or impede
the execution of any power herein granted or delegated to the Trustee or Beneficiary, but to suffer and permit the execution of every power as though no such law or laws had been made or
enacted. Trustor hereby waives the right to require any sale to be made in parcels, or the right to select parcels to be so sold, and there shall be no requirement for marshalling of assets. Trustor
hereby

10

---

further waives any rights it may have under applicable law relating to the prohibition of the obtaining of a deficiency judgment by Beneficiary against Trustor.

SECTION 2.07.Intentionally Deleted.

SECTION 2.08.Without affecting the personal liability of any person, firm, corporation or other entity, including
Trustor (other than any person released pursuant hereto), for the payment of the indebtedness secured hereby, and without affecting the lien of this Deed of Trust for the full amount of the
indebtedness remaining unpaid upon any property not reconveyed pursuant hereto, Beneficiary and Trustee are respectively authorized and empowered as follows: Beneficiary may, at any time and from time
to time, either before or after the maturity of the Notes or the expiration of the Credit Agreement, and without notice: (a) release any person liable for the payment of any of the
indebtedness, (b) make any agreement extending the time or otherwise altering the terms of payment of any of the indebtedness, (c) accept additional security therefor of any kind,
(d) release any property, real or personal, securing the indebtedness. Trustee may, without liability therefor and without notice, at any time and from time to time so long as the lien or
charge hereof shall subsist, but only upon the written request of Beneficiary and presentation of this Deed of Trust and the Notes for endorsement: (a) consent to the making of any map or plat
of the Land, (b) join in granting any easement thereon or in creating any covenants restricting use or occupancy thereof, (c) reconvey, without warranty, any part of the Mortgaged
Property, (d) join in any extension agreement or in any agreement subordinating the lien or charge hereof.

SECTION 2.09.This Deed of Trust constitutes a Security Agreement under the laws of the State of California so that
Beneficiary shall have and may endorse a security interest in any or all of the Mortgaged Property which may or might now or hereafter be or be deemed to be personal property, fixtures or property
other than real estate (collectively, "Personal Property") and Trustor agrees to execute, as debtor, such financing statement or statements as Beneficiary may now or hereafter reasonably request in
order that such security interest or interests may be perfected pursuant to such laws. This Deed of Trust further constitutes a fixture filing under Sections 9-334 and 9-502 of
the California Uniform Commercial Code, as amended or recodified from time to time; provided, however, that the execution and/or filing hereof does not imply that the items of Personal Property
included in the Mortgaged Property are or are to become fixtures. The filing hereof as a fixture filing is intended to protect the parties from unwarranted assertions by third parties.

11

---



Notwithstanding
any release of any or all of the property included in the Premises which is deemed "real property", any proceedings to foreclose this Deed of Trust, or its
satisfaction of record, the terms hereof shall survive as a security agreement with respect to the security interest created hereby and referred to above until the repayment or satisfaction in full of
the obligations of Trustor as are now or hereafter evidenced by the Notes and Credit Agreement.

SECTION 2.10.During the continuance of any Event of Default, Beneficiary shall have all of the rights and remedies of
a secured party under the Uniform Commercial Code (the "Code") of the State of California, and specifically the right to direct notice and collections of any obligation owing to Trustor by any lessee.
In addition to its rights to foreclose this Deed of Trust, Beneficiary shall have the right to sell the Personal Property or any part thereof, or any further, or additional, or substituted Personal
Property, at one or more times, and from time to time, at public sale or sales or at private sale or sales, on such terms as to cash or credit, or partly for cash and partly on credit, as Beneficiary
may deem proper. Beneficiary shall have the right to become the purchaser at any such public sale or sales, free and clear of any and all claims, rights of equity of redemption in Trustor, all of
which are hereby waived and released. Trustor shall not be credited with the amount of any part of such purchase price, unless, until and only to the extent that such payment is actually received in
cash. Notice of public sale, if given, shall be sufficiently given, for all purposes, if published not less than seven days prior to any sale, in any newspaper of general circulation distributed in

right, title and interest in and to the Mortgaged Property by paying to Beneficiary the applicable Minimum Price or repayment in full of the Term Loan in accordance with the provisions of
