Enclosed with this letter are amended and
restated versions (the “Amended Agreements”) of the following agreements which were originally entered into between
Eos Petro, Inc. and Clouding IP, LLC on December 26, 2012 (the “”Original Agreements”): (1) an Oil & Gas
Services Agreement; (2) a Warrant to Purchase Common Stock; (3) a Loan Agreement and Secured Promissory Note; and (4) a Leasehold
Mortgage, Assignment, Security Agreement and Fixture Filing.

 

The Amended Agreements modify the following
provisions of the Original Agreements:

 

(1) all of the agreements are
now between Clouding IP, LLC and Cellteck, Inc., not Eos Petro, Inc. (Cellteck Inc. is Eos Petro, Inc.’s parent company).
Since Cellteck is incorporated under Nevada law, the governing law in all of the agreements other than the Mortgage has also been
changed to Nevada.

 

(2) the shares issuable to Clouding
IP, LLC under the Loan Agreement and Secured Promissory Note have been changed from shares of common stock of Eos Petro, Inc. to
shares of Series B Preferred Stock of Cellteck, Inc.

 

(3) The obligation to record
the loan within seven business days has been removed from the Loan Agreement and Secured Promissory Note.

 

(4) “Failure to Deliver
Common Stock” has been removed from the events of default in the Loan Agreement and Secured Promissory note.

 

(5) the shares issuable to Clouding
IP, LLC upon exercise of the Warrant to Purchase Common Stock have been changed to shares of common stock of Cellteck, Inc. Furthermore,
to protect such shares from dilution upon the occurrence of an upcoming reverse stock split:

 

(a) the warrants will not be
exercisable until effectuation of the reverse stock split; and

 

(b) anti-dilution provisions specifically
relating to the upcoming reverse stock split have been inserted.

 

(6) the cashless exercise option
has been removed from the Warrant to Purchase Common Stock.

 

(7) the warrants issuable to
Clouding IP, LLC under the Oil & Gas Services Agreement are issuable in consideration of Clouding IP, LLC’s services
without the need for Clouding to make an additional $5,000 payment.

 

The Amended Agreements amend and restate
the Original Agreements in their entirety. By signing this letter and the attached Amended Agreements, the undersigned parties
hereby acknowledge that: (i) they have read, understand and consent to the modifications made to the Original Agreements in the
Amended Agreements; and (ii) the Original Agreements are voided in their entirety by the attached Amended Agreements and have no
further effect.

CELLTECK, INC.

 

WARRANT TO PURCHASE COMMON STOCK

 

**** 1,000,000 Shares of Common Stock ****

 

THIS WARRANT CERTIFIES
THAT, for value received, Clouding IP, LLC, or registered assigns (the “Holder”), is entitled to subscribe
for and purchase from Cellteck, Inc., a Nevada corporation (the “Company”), with its principal offices located
at 1999 Avenue of the Stars, Suite 2520, Los Angeles, California 90067, up to and including the number of fully paid and nonassessable
shares of common stock, par value $0.0001 per share (the “Common Stock”) of the Company set forth above (the
“Warrant Shares”), at the exercise price of $3.00 per share (the “Warrant Exercise Price”)
(and as adjusted from time to time pursuant to Section 3 hereof), in accordance with the exercise procedure set forth in Section
1 hereof and prior to or upon December 25, 2015 (the “Expiration Date”), subject to the provisions and upon
the terms and conditions hereinafter set forth.

 

This Warrant is issued
in connection with a certain Oil & Gas Services Agreement, dated as of the date hereof (as amended, modified or supplemented,
the “Services Agreement”), between Company and Holder. Pursuant to the Services Agreement, the Holder, for and
behalf of itself and its affiliated companies, has agreed to provide certain services to the Company. Terms used but not defined
in this Warrant shall have the meanings given in the Services Agreement (together with this Warrant, the “Services Documents”).

 

1.          Exercise
Procedure; Method of Exercise; Cash Payment; Issuance of New Warrant.

 

(a)          On
October 12, 2012, pursuant to an Agreement and Plan of Merger dated July 16, 2012 (the “Merger Agreement”),
Company completed a merger transaction. In the Merger Agreement, the Company agreed to implement a reverse stock split at an exchange
ratio of 1-for-800 of its outstanding shares of common stock as soon as reasonably practicable following the completion of the
Merger (the “Merger Reverse Split”). This Warrant shall not be exercisable by Holder unless and until the Merger
Reverse Split has been effectuated by the filing of an amendment to the Company’s Articles of Incorporation with the Nevada
Secretary of State. Thereafter, the Warrant shall be exercisable by Holder, in whole or in part and from time to time, at any time
until the Expiration Date, at the election of the Holder hereof.

 

(b)          If
Holder elects to exercise this Warrant, Holder shall surrender this Warrant (with the notice of exercise substantially in the form
attached hereto as Exhibit A duly completed and executed) at the principal executive offices of Company, accompanied
by payment to Company, by: (a) certified or bank check acceptable to Company; (b) cancellation by Holder of bona fide indebtedness
of Company to Holder, if agreed to in advance in writing by Company in the Company’s sole and absolute discretion; (c) by
wire transfer to an account designated by Company; or (d) any combination of (a), (b) and (c), of an amount equal to the then applicable
Warrant Exercise Price multiplied by the number of Warrant Shares then being purchased.

 

    	3

    	 

    

 

(c)          The
person or persons in whose name(s) any certificate(s) representing the Warrant Shares shall be deemed to have become the holder(s)
of record of, and shall be treated for all purposes as the record holder(s) of, the shares represented thereby (and such shares
shall be deemed to have been issued) immediately prior to the close of business on the date or dates upon which this Warrant is
exercised. In the event of any exercise of the rights represented by this Warrant, certificates for the Warrant Shares so purchased
shall be delivered to the Holder hereof as soon as possible and in any event within five (5) Business Days after such exercise
and, unless this Warrant has been fully exercised or expired, a new warrant having the same terms as this Warrant and representing
the remaining portion of such shares, if any, with respect to which this Warrant shall not then have been exercised shall also
be issued to the Holder hereof as soon as possible and in any event within such five (5) Business Day period. For purposes of this
Warrant, the term “Business Day” means any day other than Saturday, Sunday or other day on which commercial
banks in Los Angeles, California are authorized or required by law to remain closed.

 

2.          Reservation
of Shares. During the period within which the rights represented by this Warrant may be exercised, the Company will at all
times have authorized, and reserved for the purpose of the issuance upon exercise of the purchase rights evidenced by this Warrant
a sufficient number of shares of its capital stock to provide for the exercise of the rights represented by this Warrant.

 

3.          Adjustment
of Warrant Exercise Price and Number of Shares. The number and kind of securities purchasable upon the exercise of this Warrant
and the Warrant Exercise Price shall be subject to adjustment to the nearest whole share (one-half and greater being rounded upward)
and nearest cent (one-half cent and greater being rounded upward) from time to time upon the occurrence of certain events, as follows.
Each of the adjustments provided by the subsections below shall be deemed separate adjustments and any adjustment of this
Warrant pursuant to one subsection of this Section 3 shall preclude additional adjustments for the same event or transaction
by the remaining subsections.

 

(a)          Merger
Reverse Split. When the Merger Reverse Split is implemented, it shall have no effect on this Warrant. Neither the Exercise
Price nor the number of shares issuable upon exercise of this warrant shall be increased or decreased on account of the Merger
Reverse Split.

 

(b)          Reclassification.
Except as provided above in Section 3(a), in case of any reclassification or change of securities of the class issuable upon exercise
of this Warrant (other than a change in par value, or from par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination) into the same or a different number or class of securities, the Company shall duly execute
and deliver to the Holder of this Warrant a new warrant (in form and substance reasonably satisfactory to the Holder of this Warrant),
so that the Holder of this Warrant shall thereafter be entitled to receive upon exercise of this Warrant, at a total purchase price
not to exceed that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the shares of Common Stock
theretofore issuable upon exercise of this Warrant, the kind and amount of shares of stock, other securities, money and property
receivable upon such reclassification or change by a holder of the number of shares then purchasable under this Warrant. The Company
shall deliver such new warrant as soon as possible and in any event within five (5) Business Days after such reclassification or
change. Such new warrant shall provide for adjustments that shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Section 3. The provisions of this subparagraph (a) shall similarly apply to successive reclassifications or
changes.

 

    	4

    	 

    

 

(c)          Stock
Splits or Combination of Shares. Except as provided above in Section 3(a), if the Company at any time while this Warrant remains
outstanding and unexpired shall subdivide (by stock split) or combine (by reverse stock split) its outstanding shares of capital
stock of the class into which this Warrant is exercisable, the Warrant Exercise Price shall be proportionately decreased in the
case of a subdivision or increased in the case of a combination, effective at the close of business on the date the subdivision
or combination becomes effective and the number of shares of Common Stock issuable upon exercise of this Warrant shall be proportionately
increased in the case of a subdivision or decreased in the case of a combination, and in each case to the nearest whole share,
effective at the close of business on the date the subdivision or combination becomes effective. The provisions of this subparagraph
(b) shall similarly apply to successive subdivisions or combinations of outstanding shares of capital stock into which this Warrant
is exercisable.

 

(d)          Common
Stock Dividends. If the Company at any time while this Warrant is outstanding and unexpired shall pay a dividend with respect
to Common Stock payable in Common Stock, then: (i) the Warrant Exercise Price shall be adjusted, from and after the date of determination
of stockholders entitled to receive such dividend or distribution (the “Record Date”), to that price determined
by multiplying the Warrant Exercise Price in effect immediately prior to such date of determination by a fraction (A) the numerator
of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and
(B) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or
distribution and (ii) the number of shares of Common Stock issuable upon exercise of this Warrant shall be proportionately adjusted,
to the nearest whole share, from and after the Record Date by multiplying the number of shares of Common Stock purchasable hereunder
immediately prior to such Record Date by a fraction (A) the numerator of which shall be the total number of shares of Common Stock
outstanding immediately after such dividend or distribution, and (B) the denominator of which shall be the total number of shares
of Common Stock outstanding immediately prior to such dividend or distribution. The provisions of this subparagraph (c) shall similarly
apply to successive Common Stock dividends by the Company.

 

(e)          Certain
Issuance of Securities. If the Company shall at any time or from time to time while this Warrant is outstanding (A) issue
shares of Common Stock, stock or securities (other than Options) directly or indirectly convertible into or exchangeable or exercisable
for Common Stock (“Convertible Securities”), or rights, warrants or options to subscribe for or purchase shares
of Common Stock or Convertible Securities (“Options”) entitling the recipient thereof to subscribe for or purchase
shares of Common Stock, at a price per share or (B) amend or otherwise modify the terms of any Convertible Securities or Options
to a price per share (such issuance, subscription or purchase price or amended or modified price being referred to as the “New
Issue Price”), in either case, less than the Warrant Exercise Price then in effect, then the Warrant Exercise Price in
effect at the opening of business on the day next following such issuance shall be adjusted to equal the New Issue Price.  Such
adjustment shall become effective immediately upon the opening of business on the day next following such issuance.  In determining
whether any shares of Common Stock are issued or issuable, or Convertible Securities or Options entitle the holders of Warrants
to subscribe for or purchase shares of Common Stock at less than such Warrant Exercise Price, there shall be taken into account
any consideration received by the Company upon issuance of any such securities, the conversion of any such Convertible Securities
and upon exercise of such Options the value of such consideration, if other than cash, to be determined in good faith by the Board
of Directors of the Company in the exercise of their fiduciary duty, with the concurrence of the holders of at least a majority
of the Warrants then outstanding.  Notwithstanding the foregoing or any other provision herein to the contrary, no adjustment
to the Warrant Exercise Price will be required as a result of any (i) shares of Common Stock issued or deemed to have been
issued by the Company pursuant to an employee benefit plan that has been approved by the Board of Directors and stockholders of
the Company prior to or on the date of the Services Agreement, pursuant to which the Company’s securities may be issued to
any consultant, employee, officer or director for services provided to the Company (an “Approved Stock Plan”);
(ii) shares issued or deemed to have been issued upon the conversion, exchange or exercise of any Option or Convertible Security
outstanding on the date prior to or on the date of the Services Agreement, provided that the terms of such Option or Convertible
Security are not amended or otherwise modified on or after the date of the Services Agreement, and provided that the conversion
price, exchange price, exercise price or other purchase price is not reduced, adjusted or otherwise modified and the number of
shares of Common Stock issued or issuable is not increased (whether by operation of, or in accordance with, the relevant governing
documents or otherwise) on or after the date of the Services Agreement; and (ii) shares of the Common Stock issued or deemed
to have been issued by the Company upon exercise of this Warrant (each such issuance, an “Exempted Issuance”).

 

    	5

    	 

    

 

(f)          Certain
Distributions. Except as provided above in Section 3(a), in case the Company shall at any time or from time to time while this
Warrant is outstanding distribute to all holders of shares of Common Stock (including any such distribution made in connection
with a merger or consolidation in which the Company is the resulting or surviving person and the Common Stock is not changed or
exchanged) cash, evidences of indebtedness of the Company, any subsidiary or another issuer, securities of the Company (including
Convertible Securities), any subsidiary or another issuer or other assets (excluding dividends payable in shares of Common Stock
for which adjustment is made under another paragraph of this Section 3 and any distribution in connection with an Exempted
Issuance) or Options to subscribe for or purchase of any of the foregoing, then, and in each such case, the Warrant Exercise
Price then in effect shall be adjusted (and any other appropriate actions shall be taken by the Company) by multiplying the Warrant
Exercise Price in effect immediately prior to the date of such distribution by a fraction (x) the numerator of which shall be the
Weighted Average Price of the Common Stock for the five (5) consecutive Trading Days immediately prior to the date of distribution
less the then fair market value (as determined by the Board of Directors in the exercise of their fiduciary duties with the concurrence
of the holders of at least a majority of the Warrants then outstanding) of the portion of the cash, evidences of indebtedness,
securities or other assets so distributed or of such Options to subscribe applicable to one share of Common Stock and (y) the denominator
of which shall be the Weighted Average Price of the Common Stock for the five (5) consecutive Trading Days immediately prior
to the date of distribution (but such fraction shall not be greater than one).  Such adjustment shall be made whenever any
such distribution is made and shall become effective retroactively to a date immediately following the close of business on the
record date for the determination of stockholders entitled to receive such distribution.

 

(g)          Tender
Offer. In the event that the Company shall at any time or from time to time while this Warrant is outstanding make a payment
of cash or other consideration to the holders of shares of Common Stock in respect of a tender offer or exchange offer, other than
an odd-lot offer, and the value of the sum of (i) the aggregate cash and other consideration paid for such shares of Common
Stock, and (ii) any other consent or other fees paid to holders of shares of Common Stock in respect of such tender offer
or exchange offer, expressed as an amount per share of Common Stock validly tendered or exchanged pursuant to such tender offer
or exchange offer, exceeds the Weighted Average Price of the Common Stock on the Trading Day immediately prior to the date any
such tender offer or exchange offer is first publicly announced (the “Announcement Date”), then the Warrant
Exercise Price shall be adjusted in accordance with the formula:

 

	R’ =	   R (O’ x P)
	 	F + (P x O)

 

For purposes of the foregoing
formula: 

 

R = the Warrant Exercise
Price in effect at the expiration time of the tender offer or exchange offer that is the subject of this Section 4(e)(iv) (the
“Expiration Time”);

 

    	6

    	 

    

 

R’ = the Warrant
Exercise Price in effect immediately after the expiration time;

 

F = the fair market value
(as determined by the Board of Directors in the exercise of their fiduciary duties with the concurrence of the Holder) of the aggregate
value of all cash and any other consideration paid or payable for shares of Common Stock validly tendered or exchanged and not
withdrawn prior to the Expiration Time (the “Purchased Shares”);

 

O = the number of shares
of Common Stock outstanding immediately after the Expiration Time less any Purchased Shares;

 

O’ = the number
of shares of Common Stock outstanding immediately after the Expiration Time, plus any Purchased Shares; and

 

P = the Weighted Average
Price of the Common Stock on the Trading Day next succeeding the Announcement Date.

 

Such decrease, if any, shall become effective
immediately upon the opening of business on the day next following the Expiration Time.  In the event that Company is obligated
to purchase shares pursuant to any tender offer, but the Company is prevented by applicable law from effecting any such purchases
or all such purchases are rescinded, the Warrant Exercise Price shall again be adjusted to the Warrant Exercise Price that would
then be in effect if such tender or exchange offer had not been made.  If the application of this Section 3(g) to
any tender or exchange offer would result in an increase in the Warrant Exercise Price, no adjustment shall be made for such tender
or exchange offer under this Section 3(g)

 

(h)          No
adjustment in the Warrant Exercise Price shall be required unless such adjustment would require a cumulative decrease of at least
$0.01 in such price; provided, however, that any adjustments that by reason of this Section 3 are not required
to be made shall be carried forward and taken into account in any subsequent adjustment until made.  All calculations under
this Section 3(h) shall be made to the nearest cent (with $.005 being rounded upward) or to the nearest one-tenth of
a share (with .05 of a share being rounded upward), as the case may be.

 

(i)          In
any case in which Section 3 provides that an adjustment shall become effective on the day next following the record date for
an event, the Company may without penalty defer until the occurrence of such event issuing to the Holder with respect to any part
of this Warrant exercised after such record date and before the occurrence of such event the additional shares of Common Stock
issuable upon such exercise by reason of the adjustment required by such event over and above the shares of Common Stock issuable
upon such conversion before giving effect to such adjustment.

 

(j)          If,
at any time or from time to time while this Warrant is outstanding any event occurs of the type contemplated by the provisions
of this Section 3 but not expressly provided for by such provisions (including the granting of stock appreciation rights,
phantom stock rights or other rights with equity features), then the Company’s Board of Directors will make an appropriate
adjustment in the Warrant Exercise Price so as to protect the rights of the holder; provided that no such adjustment will increase
the Warrant Exercise Price as otherwise determined pursuant to this Section 3.

 

4.          Notice
of Adjustments. Whenever the Warrant Exercise Price or the number of shares of Common Stock purchasable hereunder shall be
adjusted pursuant to Section 3 above, the Company shall deliver a written notice, setting forth, in reasonable detail, the event
requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated, and the Warrant Exercise
Price and the number of shares of Common Stock purchasable hereunder after giving effect to such adjustment, and shall use commercially
reasonable efforts to cause copies of such notice to be delivered to the Holder of this Warrant within three (3) Business Days
after the occurrence of the event resulting in such adjustment at such Holder’s last known address in accordance with Section
10 hereof.

 

    	7

    	 

    

 

5.          Fractional
Shares. No fractional shares will be issued in connection with any exercise hereunder, but in lieu of such fractional shares,
the number of shares of Common Stock to be issued shall be rounded up to the nearest whole number.

 

6.          Compliance
with Securities Act of 1933; Transfer of Warrant or Shares.

 

(a)          Compliance
with Securities Act of 1933. The Holder of this Warrant, by acceptance hereof, agrees that this Warrant, the Warrant Shares
and the capital stock issuable upon conversion of the Warrant Shares (collectively, the “Securities”) are being
acquired for investment and that such holder will not offer, sell, transfer or otherwise dispose of the Securities except under
circumstances which will not result in a violation of the Securities Act of 1933, as amended (the “Securities Act”)
and any applicable state securities laws. Upon exercise of this Warrant, unless the Warrant Shares being acquired are registered
under the Securities Act and any applicable state securities laws or an exemption from such registration is available, the Holder
hereof shall confirm in writing that the Warrant Shares so purchased are being acquired for investment and not with a view toward
distribution or resale in violation of the Securities Act and shall confirm such other matters related thereto as may be reasonably
requested by the Company. The Warrant Shares (unless registered under the Securities Act and any applicable state securities laws)
shall be stamped or imprinted with a legend in substantially the following form:

 

THE SECURITIES
REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”). THEY MAY
NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES
UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

 

Such legend shall be
removed by the Company, upon the request of a Holder, at such time as the restrictions on the transfer of the applicable security
shall have terminated.

 

(b)          Transferability
of the Warrant. Subject to compliance with Section 7(c) below, which provisions are intended to ensure compliance with applicable
federal and states securities laws, the Securities may be transferred by the Holder hereof, in whole or in part and from time to
time.

 

(c)          Method
of Transfer. With respect to any offer, sale, transfer or other disposition of the Securities, the Holder hereof shall prior
to such offer, sale, transfer or other disposition:

 

(i)          surrender
this Warrant or certificate representing Warrant Shares at the principal executive offices of the Company or provide evidence reasonably
satisfactory to the Company of the loss, theft or destruction of this Warrant or certificate representing Warrant Shares and an
indemnity agreement reasonable satisfactory to the Company,

 

(ii)         pay
any applicable transfer taxes or establish to the satisfaction of the Company that such taxes have been
paid,

 

    	8

    	 

    

 

(iii)        deliver
a written assignment to the Company in substantially the form attached hereto as Exhibit B or appropriate stock power
duly completed and executed prior to transfer, describing briefly the manner thereof, and

 

(iv)        deliver
a written opinion of such Holder’s counsel, or other evidence, if reasonably requested by the Company, to the effect that
such offer, sale, transfer or other disposition may be effected without registration or qualification (under the Securities Act
as then in effect and any applicable state securities law then in effect) of the Securities.

 

As soon as reasonably
practicable after receiving the items set forth above, the Company shall notify the Holder that it may sell, transfer or otherwise
dispose of the Securities, all in accordance with the terms of the notice delivered to the Company. If a determination has been
made pursuant to this Section 7(c) that the opinion of counsel for the Holder or other evidence is not reasonably satisfactory
to the Company, the Company shall so notify the Holder promptly with details of such determination. Notwithstanding the foregoing,
the Securities may, as to such federal laws, be offered, sold or otherwise disposed of in accordance with Rule 144 under the Securities
Act if the Company satisfied the provisions thereof and provided that the Holder shall furnish such information as the Company
may reasonably request to provide a reasonable assurance that the provisions of Rule 144 have been satisfied. Each certificate
representing this Warrant or Warrant Shares thus transferred (except a transfer pursuant to Rule 144 or an effective registration
statement) shall bear a legend as to the applicable restrictions on transferability in order to ensure compliance with applicable
federal and state securities laws, unless in the aforesaid opinion of counsel to the Holder and to the reasonable satisfaction
of the Company, such legend is not required in order to ensure compliance with such laws. Upon any partial
transfer of this Warrant, the Company will issue and deliver to such new holder a new warrant (in form and substance similar
to this Warrant) with respect to the portion transferred and will issue and deliver to the Holder a
new warrant (in form and substance similar to this Warrant) with respect to the portion not transferred
as soon as possible and in any event within five (5) Business Days after such transfer.

 

7.          No
Rights as Shareholders; Information. Prior to exercise of this Warrant, the Holder of this Warrant, as such, shall not be entitled
to vote the Warrant Shares or receive dividends on or be deemed the holder of such shares, nor shall anything contained herein
be construed to confer upon the Holder of this Warrant, as such, any of the rights of a shareholder of the Company or any right
to vote for the election of directors or upon any matter submitted to shareholders at any meeting thereof, or to receive notice
of meetings, or to receive dividends or subscription rights or otherwise until this Warrant shall have been exercised and the shares
of Common Stock purchasable upon the exercise hereof shall have become deliverable, as provided herein.

 

8.          Modification
and Waiver; Effect of Amendment or Waiver. This Warrant and any provision hereof may be modified, amended, waived, discharged
or terminated only by an instrument in writing, designated as an amendment to this Warrant and executed by a duly authorized officer
of the Company and the Holder of this Warrant. Any waiver or amendment effected in accordance with this Section 9 shall be binding
upon the Holder, each future holder of this Warrant or of any shares purchased under this Warrant (including securities into which
such shares have been converted) and the Company.

 

    	9

    	 

    

 

9.          Notices.
Any notice, request, communication or other document required or permitted to be given or delivered to the Holder hereof or the
Company shall be delivered by personal delivery, or shall be sent by certified United States mail, first-class postage prepaid
or by overnight delivery using a nationally recognized courier service, to each such holder at its address as shown on the books
of the Company or to the Company at the address first set forth above in this Warrant. All such notices, requests, communications
or other documents shall be deemed to have been received by the recipient: (i) in the case of personal delivery, on the date of
such delivery, (ii) in the case of delivery by a nationally recognized courier service, on the next Business Day subsequent to
deposit with the courier and (iii) in the case of mailing, on the fourth Business Day following the date of deposit in the United
States mails, first-class postage prepaid. The Company will give written notice to the holder of this Warrant at least ten (10) Business
Days prior to the date on which the Company closes its books or takes a record (A) with respect to any dividend or distribution
upon the Common Stock, (B) with respect to any pro rata subscription offer to holders of Common Stock or (C) for determining
rights to vote with respect to any recapitalization, reorganization, reclassification, consolidation, merger, self tender offer
for all or substantially all shares of Common Stock, sale of all or substantially all of the Company’s assets to another
Person or other transaction that is effected in such a way that holders of Common Stock are entitled to receive (either directly
or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock (an “Organic
Change”), dissolution or liquidation, provided that such information shall be made known to the public prior to
or in conjunction with such notice being provided to such holder to the extent it is material non-public information.  The
Company will also give written notice to the holder of this Warrant at least ten (10) Business Days prior to the date on which
any Organic Change, dissolution or liquidation will take place, provided that such information shall be made known to the
public prior to or in conjunction with such notice being provided to such holder to the extent it is material non-public information.

 

10.         Successors.
The obligations of the Company relating to the Warrant Shares shall inure to the benefit of the successors and assigns of the Holder
hereof and shall be binding upon any successor entity. Upon such event, the successor entity shall assume the obligations of this
Warrant, and this Warrant (or any substitute warrant as provided hereinbefore) shall be exercisable for the securities, cash and
property of the successor entity on the terms provided herein.

 

11.         Lost
Warrants or Stock Certificates. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction
or mutilation of this Warrant or any stock certificate and, in the case of any such loss, theft or destruction, upon receipt of
an indemnity agreement reasonably satisfactory to the Company, or in the case of any such mutilation upon surrender and cancellation
of such mutilated Warrant or stock certificate, the Company will issue and deliver a new warrant (containing the same terms as
this Warrant) or stock certificate, in lieu of the lost, stolen, destroyed or mutilated Warrant or stock certificate.

 

12.         Descriptive

BASE RENT ABATEMENT. Notwithstanding
anything in this Section of the Lease to the contrary, so long as Tenant is not in Default (as defined in Section 19) under
this Lease, Tenant shall be entitled to an abatement of Base Rent in the amount of $15,165.95 per month for four (4) full calendar
months of the Term commencing February 1, 2013. The total amount of Base Rent abated in accordance with the foregoing shall
equal $60,663.80 (the "Abated Base Rent"). If Tenant Defaults at any time during the Term and fails to
cure such Default within any applicable cure period under the Lease, all unamortized Abated Base Rent (i.e. based upon the amortization
of the Abated Base Rent in equal monthly amounts during the initial Term, without interest) shall immediately become due and payable.
The payment by Tenant of the Abated Base Rent in the event of a Default shall not limit or affect any of Landlord's other rights,
pursuant to this Lease or at law or in equity. Only Base Rent shall be abated pursuant to this Section, and all Additional Rent
(as defined in Section 3 of the Lease) and other costs and charges specified in this Lease shall remain as due and payable
pursuant to the provisions of this Lease.

	 	 	“Base Year” for Taxes:	Calendar year 2013.
	 	 	 	 
	 	1.6	“Tenant’s Share”:	0.3794%
    (based upon a total of 824,106
    rentable square feet in the Building), subject to Section 2.1.1.
	 	 	 	 
	 	1.7	“Permitted Use”:	General office use consistent with a first-class office building; provided that in no event shall the Premises, or any portion of the Premises, be used (i) for the operation of a sundry snack business or the sale of frozen yogurt, (ii) for the sale of gourmet coffee, espresso, cappuccino or other similar specialty coffee beverage, and (iii) for the operation of a desk-top publishing center, or retail fax, copying or printing services center.

on-site parking passes that Tenant is obligated to lease during the entire Term and any extension thereof at
the rate of $225.00 per on-site unreserved pass, per month, plus applicable taxes, if any, as such rate may be adjusted from time
to time to reflect Landlord’s parking operator’s then current rates for on-site unreserved parking.

         
        

        Prior
        to the Commencement Date, Tenant shall notify Landlord in writing of the number of unreserved on-site parking passes which Tenant
        initially elects to use during the Term, but in no event in excess of the maximum nor less than the minimum number of on-site unreserved
        parking passes set forth herein. Thereafter, Tenant may increase or decrease the number of on-site unreserved parking passes to
        be used by Tenant pursuant to this Section 1.9
        upon a minimum of 30 days prior written notice to Landlord, provided that in no event may Tenant elect to use in excess of the
        maximum nor less than the minimum number of on-site unreserved parking passes set forth herein.

2.1      The
Premises.

 

2.1.1     Subject
to the terms hereof, Landlord hereby leases the Premises to Tenant and Tenant hereby leases the Premises from Landlord. Landlord
and Tenant acknowledge that the rentable square footage of the Premises is as set forth in Section 1.2.2 and the rentable
square footage of the Building is as set forth in Section 1.6; provided, however, that Landlord may from time to time re-measure
the Premises and/or the Building in accordance with any generally accepted measurement standards selected by Landlord and adjust
Tenant’s Share based on such re-measurement; provided further, however, that any such re-measurement shall not affect the
amount of Base Rent payable for, or the amount of any tenant allowance applicable to, the initial Term. At any time Landlord may
deliver to Tenant a notice substantially in the form of Exhibit C,
as a confirmation of the information set forth therein. Tenant shall execute and return (or, by notice to Landlord, reasonably
object to) such notice within five (5) days after receiving it, and if Tenant fails to do so, Tenant shall be deemed to have executed
and returned it without exception.

 

2.1.2     Except
as expressly provided herein, the Premises are accepted by Tenant in their configuration and condition existing on the date hereof
(or in such other configuration and condition as any existing tenant of the Premises may cause to exist in accordance with its
lease), without any obligation of Landlord to perform or pay for any alterations to the Premises, and without any representation
or warranty regarding the configuration or condition of the Premises, the Building or the Project or their suitability for Tenant’s
business.

 

    	4

    	 

    

 

2.2      Common
Areas. Tenant may use, in common with Landlord and other parties and subject to the Rules
and Regulations (defined in Exhibit D), any portions of the Property that are designated
from time to time by Landlord for such use (the “Common Areas”).

 

3        RENT.
Tenant shall pay all Base Rent and Additional Rent (defined below) (collectively, “Rent”)
to Landlord or Landlord’s agent, without prior notice or demand or any setoff or deduction, at the place Landlord may designate
from time to time, in money of the United States of America that, at the time of payment, is legal tender for the payment of all
obligations. As used herein, “Additional Rent” means all amounts, other than
Base Rent, that Tenant is required to pay Landlord hereunder. Monthly payments of Base Rent and monthly payments of Additional
Rent for Expenses (defined in Section 4.2.2), Taxes (defined in Section 4.2.3) and parking (collectively, “Monthly
Rent”) shall be paid in advance on or before the first day of each calendar month during
the Term; provided, however, that the installment of Base Rent for the first full calendar month for which Base Rent is payable
hereunder shall be paid upon Tenant’s execution and delivery hereof. Except as otherwise provided herein, all other items
of Additional Rent shall be paid within 30 days after Landlord’s request for payment. Rent for any partial calendar month
shall be prorated based on the actual number of days in such month. Without limiting Landlord’s other rights or remedies,
(a) if any installment of Rent is not received by Landlord or its designee within five (5) business days after its due date, Tenant
shall pay Landlord a late charge equal to five percent (5%) of the overdue amount; and (b) any Rent that is not paid within 10
days after its due date shall bear interest, from its due date until paid, at the lesser of 10%
per annum or the highest rate permitted by Law (defined in Section 5). Tenant’s covenant to pay Rent is independent
of every other covenant herein.

 

		4	EXPENSES
                                                                              AND TAXES.

 

4.1      General
Terms. In addition to Base Rent, Tenant shall pay, in accordance with Section 4.4,
for each Expense Year (defined in Section 4.2.1), an amount equal to the sum of (a) Tenant’s Share of any amount (the
“Expense Excess”) by which Expenses for such Expense Year exceed Expenses
for the Base Year, plus (b) Tenant’s Share of any amount (the “Tax Excess”)
by which Taxes for such Expense Year exceed Taxes for the Base Year. No decrease in Expenses or Taxes for any Expense Year below
the corresponding amount for the Base Year shall entitle Tenant to any decrease in Base Rent or any credit against amounts due
hereunder. Tenant’s Share of the Expense Excess and Tenant’s Share of the Tax Excess for any partial Expense Year shall
be prorated based on the number of days in such Expense Year.

 

4.2      Definitions.

actual or imputed interest on the amortized cost) over such period of time as Landlord shall reasonably determine); (b) depreciation;
(c) principal payments of mortgage or other non-operating debts of Landlord; (d) costs of repairs to the extent Landlord is reimbursed
by insurance or condemnation proceeds; (e) except as provided in clause (xiii) above, costs of leasing space in the Building, including
brokerage commissions, lease concessions, rental abatements and construction allowances granted to specific tenants; (f) costs
of selling, financing or refinancing the Building; (g) fines, penalties or interest resulting from late payment of Taxes or Expenses;
(h) organizational expenses of creating or operating the entity that constitutes Landlord; or (i) damages paid to Tenant hereunder
or to other tenants of the Building under their respective leases.

 

If, during any portion
of the Base Year or any Expense Year, the Building is not 100% occupied (or a service provided by Landlord to tenants of the Building
generally is not provided by Landlord to a tenant that provides such service itself, or any tenant of the Building is entitled
to free rent, rent abatement or the like), Expenses for such year shall be determined as if the Building had been 100% occupied
(and all services provided by Landlord to tenants of the Building generally had been provided by Landlord to all tenants, and no
tenant of the Building had been entitled to free rent, rent abatement or the like) during such portion of such year. If insurance,
security or utility costs for any Expense Year are less than insurance, security or utility costs, respectively, for the Base Year,
then, for purposes of determining Expenses for such Expense Year, such costs for such Expense Year shall be deemed to be increased
so as to be equal to such corresponding costs for the Base Year. Notwithstanding any contrary provision hereof, Expenses for the
Base Year shall exclude (a) any market-wide cost increases resulting from extraordinary circumstances, including Force Majeure
(defined in Section 25.2), boycotts, strikes, conservation surcharges, embargoes or shortages, and (b) at Landlord’s
option, the cost of any repair or replacement that Landlord reasonably expects will not recur on an annual or more frequent basis.

 

4.2.3     “Taxes”
means all federal, state, county or local governmental or municipal taxes, fees, charges, assessments, levies, licenses or other
impositions, whether general, special, ordinary or extraordinary, that are paid or accrued during the Base Year or any Expense
Year (without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection
with the ownership, leasing or operation of the Property. Taxes shall include (a) real estate taxes; (b) general and special assessments;
(c) transit taxes; (d) leasehold taxes; (e) personal property taxes imposed upon the fixtures, machinery, equipment, apparatus,
systems, appurtenances, furniture and other personal property used in connection with the Property; (f) any tax on the rent, right
to rent or other income from any portion of the Property or as against the business of leasing any portion of the Property; and
(g) any assessment, tax, fee, levy or charge imposed by any governmental agency, or by any non-governmental entity pursuant to
any private cost-sharing agreement, in order to fund the provision or enhancement of any fire-protection, street-, sidewalk- or
road-maintenance, refuse-removal or other service that is (or, before the enactment of Proposition 13, was) normally provided by
governmental agencies to property owners or occupants without charge (other than through real property taxes). Any costs and expenses
(including reasonable attorneys’ and consultants’ fees) incurred in attempting to protest, reduce or minimize Taxes
shall be included in Taxes for the year in which they are incurred. Notwithstanding any contrary provision hereof, Taxes shall
be determined without regard to any “green building” credit and shall exclude (i) all excess profits taxes, franchise
taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other
taxes to the extent (x) applicable to Landlord’s general or net income (as opposed to rents, receipts or income attributable
to operations at the Property), or (y) measured solely by the square footage, rent, fees, services, tenant allowances or similar
amounts, rights or obligations described or provided in or under any particular lease, license or similar agreement or transaction
at the Building; (ii) any Expenses, and (iii) any items required to be paid or reimbursed by Tenant under Section 4.5.

 

4.3      Allocation.
Landlord, in its reasonable discretion, may equitably allocate Expenses among office, retail or other portions or occupants of
the Property. If Landlord incurs Expenses or Taxes for the Property together with another property, Landlord, in its reasonable
discretion, shall equitably allocate such shared amounts between the Property and such other property.

4.4      Calculation
and Payment of Expense Excess and Tax Excess.

 

4.4.1     Statement
of Actual Expenses and Taxes; Payment by Tenant. Landlord shall endeavor to give to Tenant,
after the end of each Expense Year, a statement (the “Statement”) setting
forth the actual Expenses, Taxes, Expense Excess and Tax Excess for such Expense Year. If the amount paid by Tenant for such Expense
Year pursuant to Section 4.4.2 is less or more than the sum of Tenant’s Share of the actual Expense Excess plus Tenant’s
Share of the actual Tax Excess (as such amounts are set forth in such Statement), Tenant shall pay Landlord the amount of such
underpayment, or receive a credit in the amount of such overpayment, with or against the Rent then or next due hereunder; provided,
however, that if this Lease has expired or terminated and Tenant has vacated the Premises, Tenant shall pay Landlord the amount
of such underpayment, or Landlord shall pay Tenant the amount of such overpayment (less any Rent due), within 30 days after delivery
of such Statement. Any failure of Landlord to timely deliver the Statement for any Expense Year shall not diminish either party’s
rights under this Section 4.

 

4.4.2     Statement
of Estimated Expenses and Taxes. Landlord shall endeavor to give to Tenant, for each Expense
Year, a statement (the “Estimate Statement”) setting forth Landlord’s
reasonable estimates of the Expenses, Taxes, Expense Excess (the “Estimated Expense Excess”)
and Tax Excess (the “Estimated Tax Excess”) for such Expense Year. Upon receiving
an Estimate Statement, Tenant shall pay, with its next installment of Base Rent, an amount equal to the excess of (a) the amount
obtained by multiplying (i) the sum of Tenant’s Share of the Estimated Expense Excess plus Tenant’s Share of the Estimated
Tax Excess (as such amounts are set forth in such Estimate Statement), by (ii) a fraction, the numerator of which is the number
of months that have elapsed in the applicable Expense Year (including the month of such payment) and the denominator of which is
12, over (b) any amount previously paid by Tenant for such Expense Year pursuant to this Section 4.4.2. Until Landlord delivers
a new Estimate Statement (which Landlord may do at any time), Tenant shall pay monthly, with the monthly Base Rent installments,
an amount equal to one-twelfth (1/12) of the sum of Tenant’s Share of the Estimated Expense Excess plus Tenant’s Share
of the Estimated Tax Excess, as such amounts are set forth in the previous Estimate Statement. Any failure of Landlord to timely
deliver any Estimate Statement shall not diminish Landlord’s rights to receive payments and revise any previous Estimate
Statement under this Section 4.

 

4.4.3     Retroactive
Adjustment of Taxes. Notwithstanding any contrary provision hereof, if, after Landlord’s
delivery of any Statement, an increase or decrease in Taxes occurs for the applicable Expense Year or for the Base Year (whether
by reason of reassessment, error, or otherwise), Taxes for such Expense Year or the Base Year, as the case may be, and the Tax
Excess for such Expense Year shall be retroactively adjusted. If, as a result of such adjustment, it is determined that Tenant
has under- or overpaid Tenant’s Share of such Tax Excess, Tenant shall pay Landlord the amount of such underpayment, or receive
a credit in the amount of such overpayment, with or against the Rent then or next due hereunder; provided, however, that if this
Lease has expired or terminated and Tenant has vacated the Premises, Tenant shall pay Landlord the amount of such underpayment,
or Landlord shall pay Tenant the amount of such overpayment (less any Rent due), within 30 days after such adjustment is made.

 

4.5      Charges
for Which Tenant Is Directly Responsible. Tenant shall pay, 10 days before delinquency, any
taxes levied against Tenant’s equipment, furniture, fixtures and other personal property located in or about the Premises.
If any such taxes are levied against Landlord or its property (or if the assessed value of Landlord’s property is increased
by the inclusion therein of a value placed upon such equipment, furniture, fixtures or other personal property of Tenant), Landlord
may pay such taxes (or such increased assessment) regardless of their (or its) validity, in which event Tenant, upon demand, shall
repay to Landlord the amount so paid. If the Leasehold Improvements (defined in Section 7.1) are assessed for real property
tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord’s “building
standard” in other space in the Building are assessed, the Taxes levied against Landlord or the Property by reason of such
excess assessed valuation shall be deemed taxes levied against Tenant’s personal property for purposes of this Section
4.5. Notwithstanding any contrary provision hereof, Tenant shall pay 10 days before delinquency (or reimburse to Landlord upon
demand, if the same is required by Law to be paid by Landlord): (i) any rent tax, sales tax, service tax, transfer tax, value added
tax, use tax, business tax, gross income tax, gross receipts tax, or other tax, assessment, fee, levy or charge measured solely
by the square footage, Rent, services, tenant allowances or similar amounts, rights or obligations described or provided in or
under this Lease; and (ii) any taxes assessed upon the possession, leasing, operation, management, maintenance, alteration, repair,
use or occupancy by Tenant of any portion of the Property.

 

    	7

    	 

    

 

4.6      Books
and Records. Within 60 days after receiving any Statement (the “Review Notice
Period”), Tenant may give Landlord notice (“Review Notice”)
stating that Tenant elects to review Landlord’s calculation of the Expense Excess and/or Tax Excess for the Expense Year
to which such Statement applies and identifying with reasonable specificity the records of Landlord reasonably relating to such
matters that Tenant desires to review. Within a reasonable time after receiving a timely Review Notice (and, at Landlord’s
option, an executed confidentiality agreement as described below), Landlord shall deliver to Tenant, or make available for inspection
at a location reasonably designated by Landlord, copies of such records. Within 60 days after such records are made available to
Tenant (the “Objection Period”), Tenant may deliver to Landlord notice (an
“Objection Notice”) stating with reasonable specificity any objections to
the Statement, in which event Landlord and Tenant shall work together in good faith to resolve Tenant’s objections. Tenant
may not deliver more than one Review Notice or more than one Objection Notice with respect to any Expense Year. If Tenant fails
to give Landlord a Review Notice before the expiration of the Review Notice Period or fails to give Landlord an Objection Notice
before the expiration of the Objection Period, Tenant shall be deemed to have approved the Statement. Notwithstanding any contrary
provision hereof, Landlord shall not be required to deliver or make available to Tenant records relating to the Base Year, and
Tenant may not object to Expenses or Taxes for the Base Year, other than in connection with the first review for an Expense Year
performed by Tenant pursuant to this Section 4.6. If Tenant retains an agent to review Landlord’s records, the agent
must be with a CPA firm licensed to do business in the State of California and its fees shall not be contingent, in whole or in
part, upon the outcome of the review. Tenant shall be responsible for all costs of such review. The records and any related information
obtained from Landlord shall be treated as confidential, and as applicable only to the Premises, by Tenant, its auditors, consultants,
and any other parties reviewing the same on behalf of Tenant (collectively, “Tenant’s Auditors”).
Before making any records available for review, Landlord may require Tenant and Tenant’s Auditors to execute a reasonable
confidentiality agreement, in which event Tenant shall cause the same to be executed and delivered to Landlord within 30 days after
receiving it from Landlord, and if Tenant fails to do so, the Objection Period shall be reduced by one day for each day by which
such execution and delivery follows the expiration of such 30-day period. Notwithstanding any contrary provision hereof, Tenant
may not examine Landlord’s records or dispute any Statement if any Rent remains unpaid past its due date. If, for any Expense
Year, Landlord and Tenant determine that the sum of Tenant’s Share of the actual Expense Excess plus Tenant’s Share
of the actual Tax Excess is less or more than the amount reported, Tenant shall receive a credit in the amount of its overpayment
against Rent then or next due hereunder, or pay Landlord the amount of its underpayment with the Rent next due hereunder; provided,
however, that if this Lease has expired or terminated and Tenant has vacated the Premises, Landlord shall pay Tenant the amount
of its overpayment (less any Rent due), or Tenant shall pay Landlord the amount of its underpayment, within 30 days after such
determination.

 

5        USE;
COMPLIANCE WITH LAWS. Tenant shall not (a) use the Premises for any purpose other than the Permitted
Use, or (b) do anything in or about the Premises that violates any of the Rules and Regulations, damages the reputation of the
Project, interferes with, injures or annoys other occupants of the Building, or constitutes a nuisance. Tenant, at its expense,
shall comply with all Laws relating to (i) the operation of its business at the Project, (ii) the use, condition, configuration
or occupancy of the Premises, or (iii) the Building systems located in or exclusively serving the Premises. If, in order to comply
with any such Law, Tenant must obtain or deliver any permit, certificate or other document evidencing such compliance, Tenant shall
provide a copy of such document to Landlord promptly after obtaining or delivering it. If a change to any Common Area, the Building
structure, or any Building system located outside of and not exclusively serving the Premises becomes required under Law (or if
any such requirement is enforced) as a result of any Tenant-Insured Improvement (defined in Section 10.2.2), the installation
of any trade fixture, or any particular use of the Premises (as distinguished from general office use), then Tenant, upon demand,
shall (x) at Landlord’s option, either make such change at Tenant’s cost or pay Landlord the cost of making such change,
and (y) pay Landlord a coordination fee equal to 10% of the cost of such change. As used herein, “Law”
means any existing or future law, ordinance, regulation or requirement of any governmental authority having jurisdiction over the
Project or the parties.

 

6        SERVICES.

 

6.1      Standard
Services. Landlord shall provide the following services on all days (unless otherwise stated
below): (a) subject to limitations imposed by Law, customary heating, ventilation and air conditioning (“HVAC”)
in season during Building HVAC Hours; (b) electricity supplied by the applicable public utility, stubbed to the Premises; (c) water
supplied by the applicable public utility (i) for use in lavatories and any drinking facilities located in Common Areas within
the Building, and (ii) stubbed to the Building core for use in any plumbing fixtures located in the Premises; (d) janitorial services
to the Premises, except on weekends and Holidays; and (e) elevator service (subject to scheduling by Landlord, and payment of Landlord’s
standard usage fee, for any freight service).

 

    	8

    	 

    

 

6.2      Above-Standard
Use. Landlord shall provide HVAC
service outside Building HVAC Hours if Tenant gives Landlord such prior notice and pays Landlord such hourly cost per zone as Landlord
may require. Tenant shall not, without Landlord’s prior consent, use equipment that may affect the temperature maintained
by the air conditioning system or consume above-Building-standard amounts of any water furnished for the Premises by Landlord pursuant
to Section 6.1. If Tenant’s consumption of electricity or water exceeds the rate Landlord reasonably deems to be standard
for the Building, Tenant shall pay Landlord, upon billing, the cost of such excess consumption, including any costs of installing,
operating and maintaining any equipment that is installed in order to supply or measure such excess electricity or water. For purposes
of the preceding sentence, any consumption of electricity in a computer server room shall be deemed to exceed the standard rate
for the Building. The connected electrical load of Tenant’s incidental-use equipment shall not exceed the Building-standard
electrical design load, and Tenant’s electrical usage shall not exceed the capacity of the feeders to the Project or the
risers or wiring installation. 

 

6.3      Interruption.
Subject to Section 11, any failure to furnish, delay in furnishing, or diminution in the quality or quantity of any service
resulting from any application of Law, failure of equipment, performance of maintenance, repairs, improvements or alterations,
utility interruption, or event of Force Majeure (each, a “Service Interruption”)
shall not render Landlord liable to Tenant, constitute a constructive eviction, or excuse Tenant from any obligation hereunder.
Notwithstanding the foregoing, if all or a material portion of the Premises is made untenantable or inaccessible for more than
five (5) consecutive business days after notice from Tenant to Landlord by a Service Interruption that does not result from a Casualty
(defined in Section 11) and that Landlord can correct through reasonable efforts, then, as Tenant’s sole remedy, Monthly
Rent shall abate for the period beginning on the day immediately following such 5-business-day period and ending on the day such
Service Interruption ends, but only in proportion to the percentage of the rentable square footage of the Premises made untenantable
or inaccessible.

 

7        REPAIRS
AND ALTERATIONS.

 

7.1      Repairs.
Subject to Section 11, Tenant, at its expense, shall perform all maintenance and repairs (including replacements) to the
Premises, and keep the Premises in as good condition and repair as existed when Tenant took possession and as thereafter improved
by Landlord and/or Tenant, except for reasonable wear and tear and repairs that are Landlord’s express responsibility hereunder.
Tenant’s maintenance and repair obligations shall include (a) all leasehold improvements in the Premises, whenever and by
whomever installed or paid for, including any Tenant Improvements, any Alterations (defined in Section 7.2), and any leasehold
improvements installed pursuant to any prior lease, but excluding the Base Building (the “Leasehold Improvements”);
(b) all supplemental heating, ventilation and air conditioning units, kitchens (including hot water heaters, dishwashers, garbage
disposals, insta-hot dispensers, and plumbing) and similar facilities exclusively serving Tenant, whether located inside or outside
of the Premises, and whenever and by whomever installed or paid for; and (c) all Lines (defined in Section 23) and trade
fixtures. Notwithstanding the foregoing, Landlord may, at its option, perform such maintenance and repairs on Tenant’s behalf,
in which case Tenant shall pay Landlord, upon demand, the cost of such work plus a coordination fee equal to five
percent (5%) of such cost. Landlord shall perform all
maintenance and repairs to (i) the roof and exterior walls and windows of the Building, (ii) the Base Building, and (iii) the
Common Areas. As used herein, “Base Building” means the structural portions
of the Building, together with all mechanical (including HVAC), electrical, plumbing and fire/life-safety systems serving the
Building in general, whether located inside or outside of the Premises.

 

7.2      Alterations.
Tenant may not make any improvement, alteration, addition or change to the Premises or to any mechanical, plumbing or HVAC facility
or other system serving the Premises (an “Alteration”) without Landlord’s
prior consent, which consent shall be requested by Tenant not less than 30 days before commencement of work and shall not be unreasonably
withheld by Landlord. Notwithstanding the foregoing, Landlord’s prior consent shall not be required for any Alteration that
is decorative only (e.g., carpet installation or painting) and not visible from outside the Premises, provided that Landlord
receives 10 business days’ prior notice. For any Alteration, (a) Tenant, before commencing work, shall deliver to Landlord,
and obtain Landlord’s approval of, plans and specifications; (b) Landlord, in its discretion, may require Tenant to obtain
security for performance satisfactory to Landlord; (c) upon completion,
Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County in which the Project
is located in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall
furnish “as-built” plans
(in CAD format, if requested by Landlord)
(except for cosmetic Alterations), completion affidavits, full and final waivers
of lien in recordable form, and receipted
bills covering all labor and materials; and (d) Tenant shall pay Landlord upon demand
(i) Landlord’s reasonable out-of-pocket expenses incurred in reviewing the work, and (ii) a coordination fee equal to five
percent (5%) of the cost of the work; provided, however, that
this clause (d) shall not apply to any Tenant Improvements.

 

    	9

    	 

    

 

7.3      Tenant
Work. Before commencing any repair or Alteration (“Tenant Work”),
Tenant shall deliver to Landlord, and obtain Landlord’s approval of, (a) names of contractors, subcontractors, mechanics,
laborers and materialmen; (b) evidence of contractors’ and subcontractors’ insurance; and (c) any required governmental
permits. Tenant shall perform all Tenant Work (i) in a good and workmanlike manner using materials of a quality reasonably approved
by Landlord; (ii) in compliance with any approved plans and specifications, all Laws, the National Electric Code, and Landlord’s
construction rules and regulations; and (iii) in a manner that does not impair the Base Building. If, as a result of any Tenant
Work, Landlord becomes required under Law to perform any inspection, give any notice, or cause such Tenant Work to be performed
in any particular manner, Tenant shall comply with such requirement and promptly provide Landlord with reasonable documentation
of such compliance. Landlord’s approval of Tenant’s plans and specifications shall not relieve Tenant from any obligation
under this Section 7.3. In performing any Tenant Work, Tenant shall not use contractors, services, labor, materials or equipment
that, in Landlord’s reasonable judgment, would disturb labor harmony with any workforce or trades engaged in performing other
work or services at the Project.

 

8        LANDLORD’S
PROPERTY. All Leasehold Improvements shall become Landlord’s property upon installation
and without compensation to Tenant. Notwithstanding the foregoing, if any Tenant-Insured Improvements are not, in Landlord’s
reasonable judgment, Building-standard, then before the expiration or earlier termination hereof, Tenant shall, at Landlord’s
election, either (a) at Tenant’s expense, and except as otherwise notified by Landlord, remove such Tenant-Insured Improvements,
repair any resulting damage to the Premises or Building, and restore the affected portion of the Premises to its configuration
and condition existing before the installation of such Tenant-Insured Improvements (or, at Landlord’s election, to a Building-standard
tenant-improved configuration and condition as determined by Landlord), or (b) pay Landlord an amount equal to the estimated cost
of such work, as reasonably determined by Landlord. If Tenant fails to timely perform any work required under clause (a) of the
preceding sentence, Landlord may perform such work at Tenant’s expense. 

 

9        LIENS.
Tenant shall keep the Project free from any lien arising out of any work performed, material furnished or obligation incurred by
or on behalf of Tenant. Tenant shall remove any such lien within 10 business days after notice from Landlord, and if Tenant fails
to do so, Landlord, without limiting its remedies, may pay the amount necessary to cause such removal, whether or not such lien
is valid. The amount so paid, together with reasonable attorneys’ fees and expenses, shall be reimbursed by Tenant upon demand.

 

10      INDEMNIFICATION;
INSURANCE.

 

10.1    Waiver
and Indemnification. Tenant waives all claims against Landlord, its Security Holders (defined
in Section 17), Landlord’s managing agent(s), their (direct or indirect) owners, and the beneficiaries, trustees,
officers, directors, employees and agents of each of the foregoing (including Landlord, the “Landlord Parties”)
for (i) any damage to person or property (or resulting from the loss of use thereof), except to the extent such damage is caused
by any gross negligence, willful misconduct or breach of this Lease of or by any Landlord Party, or (ii) any failure to prevent
or control any criminal or otherwise wrongful conduct by any third party or to apprehend any third party who has engaged in such
conduct. Tenant shall indemnify, defend, protect, and hold the Landlord Parties harmless from any obligation, loss, claim, action,
liability, penalty, damage, cost or expense (including reasonable attorneys’ and consultants’ fees and expenses) (each,
a “Claim”) that is imposed or asserted by any third party and arises from
(a) any cause in, on or about the Premises, or (b) occupancy of the Premises by, or any negligence, willful misconduct or breach
of this Lease of or by, Tenant, any party claiming by, through or under Tenant, their (direct or indirect) owners, or any of their
respective beneficiaries, trustees, officers, directors, employees, agents, contractors, licensees or invitees, except to the extent
such Claim arises from any gross negligence, willful misconduct or breach of this Lease of or by any Landlord Party.
Landlord shall indemnify, defend, protect, and hold Tenant, its (direct or indirect) owners, and their respective beneficiaries,
trustees, officers, directors, employees and agents (including Tenant, the “Tenant Parties”)
harmless from any Claim that is imposed or asserted by any third party and arises from any negligence, willful misconduct or breach
of this Lease of or by any Landlord Party, except to the extent such Claim arises from any negligence, willful misconduct or breach
of this Lease of or by any Tenant Party.

 

10.2    Tenant’s
Insurance. Tenant shall maintain the following coverages in the following amounts:

 

10.2.1   Commercial
General Liability Insurance covering claims of bodily injury, personal injury and property damage arising out of Tenant’s
operations and contractual liabilities, including coverage formerly known as broad form, on an occurrence basis, with combined
primary and excess/umbrella limits of $3,000,000 each occurrence and $4,000,000 annual aggregate.

 

    	10

    	 

    

 

10.2.2   Property
Insurance covering (i) all office furniture, trade fixtures, office equipment, free-standing cabinet work, movable partitions,
merchandise and all other items of Tenant’s property in the Premises installed by, for, or at the expense of Tenant, and
(ii) any Leasehold Improvements installed by or for the benefit of Tenant, whether pursuant to this Lease or pursuant to any prior
lease or other agreement to which Tenant was a party (“Tenant-Insured Improvements”).
Such insurance shall be written on a special cause of loss form for physical loss or damage, for the full replacement cost value
(subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet
any co-insurance clauses of the policies of insurance, and shall include coverage for damage or other loss caused by fire or other
peril, including vandalism and malicious mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage
of pipes, and explosion, and providing business interruption coverage for a period of one year.

 

10.2.3   Workers’
Compensation statutory limits and Employers’ Liability limits of $1,000,000.

 

10.3    Form
of Policies. The minimum limits of insurance required to be carried by Tenant shall not limit
Tenant’s liability. Such insurance shall be issued by an insurance company that has an A.M. Best rating of not less than
A-VIII and shall be in form and content reasonably acceptable to Landlord. Tenant’s Commercial General Liability Insurance
shall (a) name the Landlord Parties and any other party designated by Landlord (“Additional Insured Parties”)
as additional insureds; and (b) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord
is excess and non-contributing with Tenant’s insurance. Landlord shall be designated as a loss payee with respect to Tenant’s
Property Insurance on any Tenant-Insured Improvements. Tenant shall deliver to Landlord, on or before the Commencement Date and
at least 15 days before the expiration dates thereof, certificates from Tenant’s insurance company on the forms currently
designated “ACORD 25” (Certificate of Liability Insurance) and “ACORD 28” (Evidence of Commercial Property
Insurance) or the equivalent. Attached to the ACORD 25 (or equivalent) there shall be an endorsement naming the Additional Insured
Parties as additional insureds, and attached to the ACORD 28 (or equivalent) there shall be an endorsement designating Landlord
as a loss payee with respect to Tenant’s Property Insurance on any Tenant-Insured Improvements, and each such endorsement
shall be binding on Tenant’s insurance company. Upon Landlord’s request, Tenant shall deliver to Landlord, in lieu
of such certificates, copies of the policies of insurance required to be carried under Section 10.2 showing that the Additional
Insured Parties are named as additional insureds and that Landlord is designated as a loss payee with respect to Tenant’s
Property Insurance on any Tenant-Insured Improvements.

 

10.4    Subrogation.
Each party waives, and shall cause its insurance carrier to waive, any right of recovery against the other party, any of its (direct
or indirect) owners, or any of their respective beneficiaries, trustees, officers, directors, employees or agents for any loss
of or damage to property which loss or damage is (or, if the insurance required hereunder had been carried, would have been) covered
by the waiving party’s property insurance. For purposes of this Section 10.4 only, (a) any deductible with respect
to a party’s insurance shall be deemed covered by, and recoverable by such party under, valid and collectable policies of
insurance, and (b) any contractor retained by Landlord to install, maintain or monitor a fire or security alarm for the Building
shall be deemed an agent of Landlord.

 

10.5    Additional
Insurance Obligations. Tenant shall maintain such increased amounts of the insurance required
to be carried by Tenant under this Section 10, and such other types and amounts of insurance covering the Premises and Tenant’s
operations therein, as may be reasonably requested by Landlord, but not in excess of the amounts and types of insurance then being
required by landlords of buildings comparable to and in the vicinity of the Building.

 

11      CASUALTY
DAMAGE. With reasonable promptness after discovering any damage to the Premises (other than
trade fixtures), or to any Common Area or Building system necessary for access to or tenantability of the Premises, resulting
from any fire or other casualty (a “Casualty”), Landlord
shall notify Tenant of Landlord’s reasonable estimate of the time required to substantially complete repair of such damage
(the “Landlord Repairs”). If, according to such estimate, the Landlord
Repairs cannot be substantially completed within 270 days after they are commenced, either party may terminate this Lease upon
60 days’ notice to the other party delivered within 10 days after Landlord’s delivery of such estimate. Within 90
days after discovering any damage to the Project resulting from any Casualty, Landlord may, whether or not the Premises are affected,
terminate this Lease by notifying Tenant if (i) any Security Holder terminates any ground lease
or requires that any insurance proceeds be used to pay any mortgage debt; (ii) any damage to Landlord’s property is not
fully covered by Landlord’s insurance policies; (iii) Landlord decides to rebuild the Building or Common Areas so that it
or they will be substantially different structurally or architecturally; (iv) the damage occurs during the last 12 months of the
Term; or (v) any owner, other than Landlord, of any damaged portion of the Project does not intend to repair such damage. If this
Lease is not terminated pursuant to this Section 11, Landlord shall promptly and diligently perform the Landlord Repairs,
subject to reasonable delays for insurance adjustment and other events of Force Majeure. The Landlord Repairs shall restore the
Premises (other than trade fixtures) and any Common Area or Building system necessary for access to or tenantability of the Premises
to substantially the same condition that existed when the Casualty occurred, except for (a) any modifications required by Law
or any Security Holder, and (b) any modifications to the Common Areas that are deemed desirable by Landlord, are consistent with
the character of the Project, and do not materially impair access to or tenantability of the Premises. Notwithstanding Section
10.4, Tenant shall assign to Landlord (or its designee) all insurance proceeds payable to Tenant under Tenant’s insurance
required under Section 10.2 with respect to any Tenant-Insured Improvements, and if the estimated or actual cost of restoring
any Tenant-Insured Improvements exceeds the insurance proceeds received by Landlord from Tenant’s insurance carrier, Tenant
shall pay such excess to Landlord within 15 days after Landlord’s demand. No Casualty and no restoration performed as required
hereunder shall render Landlord liable to Tenant, constitute a constructive eviction, or excuse Tenant from any obligation hereunder;
provided, however, that if the Premises (other than trade fixtures) or any Common Area or Building system necessary for access
to or tenantability of the Premises is damaged by a Casualty, then, during any time that, as a result of such damage, any portion
of the Premises is inaccessible or untenantable and is not occupied by Tenant, Monthly Rent shall be abated in proportion to the
rentable square footage of such portion of the Premises.

 

    	11

    	 

    

 

12       NONWAIVER.
No provision hereof shall be deemed waived by either party unless it is waived by such party expressly and in writing, and no waiver
of any breach of any provision hereof shall be deemed a waiver of any subsequent breach of such provision or any other provision
hereof. Landlord’s acceptance of Rent shall not be deemed a waiver of any preceding breach of any provision hereof, other
than Tenant’s failure to pay the particular Rent so accepted, regardless of Landlord’s knowledge of such preceding
breach at the time of such acceptance. No acceptance of payment of an amount less than the Rent due hereunder shall be deemed a
waiver of Landlord’s right to receive the full amount of Rent due, whether or not any endorsement or statement accompanying
such payment purports to effect an accord and satisfaction. No receipt of monies by Landlord from Tenant after the giving of any
notice, the commencement of any suit, the issuance of any final judgment, or the termination hereof shall affect such notice, suit
or judgment, or reinstate or extend the Term or Tenant’s right of possession hereunder.

 

13      CONDEMNATION.
If any part of the Premises, Building or Project is taken for any public or quasi-public use by power of eminent domain or by private
purchase in lieu thereof (a “Taking”) for more than 180 consecutive days,
Landlord may terminate this Lease. If more than 25% of the rentable square footage of the Premises is Taken, or access to the Premises
is substantially impaired as a result of a Taking, for more than 180 consecutive days, Tenant may terminate this Lease. Any such
termination shall be effective as of the date possession must be surrendered to the authority, and the terminating party shall
provide termination notice to the other party within 45 days after receiving written notice of such surrender date. Except as provided
above in this Section 13, neither party may terminate this Lease as a result of a Taking. Tenant shall not assert any claim
for compensation because of any Taking; provided, however, that Tenant may file a separate claim for any Taking of Tenant’s
personal property or any fixtures that Tenant is entitled to remove upon the expiration hereof, and for moving expenses, so long
as such claim does not diminish the award available to Landlord or any Security Holder and is payable separately to Tenant. If
this Lease is terminated pursuant to this Section 13, all Rent shall be apportioned as of the date of such termination.
If a Taking occurs and this Lease is not so terminated, Monthly Rent shall be abated for the period of such Taking in proportion
to the percentage of the rentable square footage of the Premises, if any, that is subject to, or rendered inaccessible by, such
Taking.

 

14      ASSIGNMENT
AND SUBLETTING.

 

14.1    Transfers.
Tenant shall not, without Landlord’s prior consent, assign, mortgage, pledge, hypothecate, encumber, permit any lien to
attach to, or otherwise transfer this Lease or any interest hereunder, permit any assignment or other transfer hereof or any interest
hereunder by operation of law, enter into any sublease or license agreement, otherwise permit the occupancy or use of any part
of the Premises by any persons other than Tenant and its employees and contractors, or permit a Change of Control (defined in
Section 14.6) to occur (each, a “Transfer”). If Tenant desires Landlord’s
consent to any Transfer, Tenant shall provide Landlord with (i) notice of the terms of the proposed Transfer, including its proposed
effective date (the “Contemplated Effective Date”), a description of the
portion of the Premises to be transferred (the “Contemplated Transfer Space”),
a calculation of the Transfer Premium (defined in Section 14.3), and a copy of all existing executed and/or proposed documentation
pertaining to the proposed Transfer, and (ii) current financial statements of the proposed transferee (or, in the case of a Change
of Control, of the proposed new controlling party(ies)) certified by an officer or owner thereof and any other information reasonably
required by Landlord in order to evaluate the proposed Transfer (collectively, the “Transfer Notice”).
Within 30 days after receiving the Transfer Notice, Landlord shall notify Tenant of (a) its consent to the proposed Transfer,
(b) its refusal to consent to the proposed Transfer, or (c) its exercise of its rights under Section 14.4. Any Transfer
made without Landlord’s prior consent shall, at Landlord’s option, be void and shall, at Landlord’s option,
constitute a Default (defined in Section 19). Tenant shall pay Landlord a fee of $1,000.00
for Landlord’s review of any proposed
Transfer, whether or not Landlord consents to it.

 

    	12

    	 

    

 

14.2    Landlord’s
Consent. Subject to Section 14.4, Landlord shall not unreasonably withhold its consent
to any proposed Transfer. Without limiting other reasonable grounds for withholding consent, it shall be deemed reasonable for
Landlord to withhold its consent to a proposed Transfer if:

 

14.2.1  The
proposed transferee is not a party of reasonable financial strength in light of the responsibilities to be undertaken in connection
with the Transfer on the date the Transfer Notice is received; or

 

14.2.2  The
proposed transferee has a character or reputation or is engaged in a business that is not consistent with the quality of the Building
or the Project; or

 

14.2.3  The
proposed transferee is a governmental entity or a nonprofit organization; or

 

14.2.4  In
the case of a proposed sublease, license or other occupancy agreement, the rent or occupancy fee charged by Tenant to the transferee
during the term of such agreement, calculated using a present value analysis, is less than 95% of the rent being quoted by Landlord
or its Affiliate (defined in Section 14.8) at the time of such Transfer for comparable space in the Project for a comparable
term, calculated using a present value analysis; or

 

14.2.5  The
proposed transferee or any of its Affiliates, on the date the Transfer Notice is received, leases or occupies (or, at any time
during the 6-month period ending on the date the Transfer Notice is received, has negotiated with Landlord to lease) space in the
Project.

 

Notwithstanding any
contrary provision hereof, (a) if Landlord consents to any Transfer pursuant to this Section 14.2 but Tenant does not enter
into such Transfer within six (6) months thereafter, such consent shall no longer apply and such Transfer shall not be permitted
unless Tenant again obtains Landlord’s consent thereto pursuant and subject to the terms of this Section 14; and (b)
if Landlord unreasonably withholds its consent under this Section 14.2, Tenant’s sole remedies shall be contract damages
(subject to Section 20) or specific performance, and Tenant waives all other remedies, including any right to terminate
this Lease.

 

14.3    Transfer
Premium. If Landlord consents to a Transfer, Tenant shall pay Landlord an amount equal to
50% of any Transfer Premium (defined below). As used herein, “Transfer Premium”
means (a) in the case of an assignment, any consideration (including payment for Leasehold Improvements) paid by the assignee for
such assignment; (b) in the case of a sublease, license or other occupancy agreement, for each month of the term of such agreement,
the amount by which all rent and other consideration paid by the transferee to Tenant pursuant to such agreement exceeds the Monthly
Rent payable by Tenant hereunder with respect to the Contemplated Transfer Space; and (c) in the case of a Change of Control, any
consideration (including payment for Leasehold Improvements) paid by the new controlling party(ies) to the prior controlling party(ies)
on account of this Lease. Payment of Landlord’s share of the Transfer Premium shall be made (x) in the case of an assignment
or a Change of Control, within 10 days after Tenant or the prior controlling party(ies), as the case may be, receive(s) the consideration
described above, and (y) in the case of a sublease, license or other occupancy agreement, for each month of the term of such agreement,
within five (5) business days after Tenant receives the rent and other consideration described above.

 

14.4    Landlord’s
Right to Recapture. Notwithstanding any contrary provision hereof, except in the case of
a Permitted Transfer (defined in Section 14.8), Landlord, by notifying Tenant within 30 days after receiving the Transfer
Notice, may terminate this Lease with respect to the Contemplated Transfer Space as of the Contemplated Effective Date. If the
Contemplated Transfer Space is less than the entire Premises, then Base Rent, Tenant’s Share, and the number of parking spaces
to which Tenant is entitled under Section 1.9 shall be deemed adjusted on the basis of the percentage of the rentable square
footage of the portion of the Premises retained by Tenant. Upon request of either party, the parties shall execute a written agreement
prepared by Landlord memorializing such termination.

 

14.5    Effect
of Consent. If Landlord consents to a Transfer, (i) such consent shall not be deemed a consent
to any further Transfer, (ii) Tenant shall deliver to Landlord, promptly after execution, an executed copy of all documentation
pertaining to the Transfer in form reasonably acceptable to Landlord, and (iii) Tenant shall deliver to Landlord, upon Landlord’s
request, a complete statement, certified by an independent CPA or Tenant’s chief financial officer, setting forth in detail
the computation of any Transfer Premium. In the case of an assignment, the assignee shall assume in writing, for Landlord’s
benefit, all of Tenant’s obligations hereunder. No Transfer, with or without Landlord’s consent, shall relieve Tenant
or any guarantor hereof from any liability hereunder. Notwithstanding any contrary provision hereof, Tenant, with or without Landlord’s
consent, shall not enter into, or permit any party claiming by, through or under Tenant to enter into, any sublease, license or
other occupancy agreement that provides for payment based in whole or in part on the net income or profit of the subtenant, licensee
or other occupant thereunder.

 

    	13

    	 

    

 

14.6    Change
of Control. As used herein, “Change of Control”
means (a) if Tenant is a closely held professional service firm, the withdrawal or change (whether voluntary, involuntary or by
operation of law) of more than 25% of its equity owners within a 12-month period; and (b) in all other cases, any transaction(s)
resulting in the acquisition of a Controlling Interest (defined below) by one or more parties that did not own a Controlling Interest
immediately before such transaction(s). As used herein, “Controlling Interest”
means any direct or indirect equity or beneficial ownership interest in Tenant that confers upon its holder(s) the direct or indirect
power to direct the ordinary management and policies of Tenant, whether through the ownership of voting securities, by contract
or otherwise (but not through the ownership of voting securities listed on a recognized securities exchange).

 

14.7    Effect
of Default. If Tenant is in Default, Landlord is irrevocably authorized, as Tenant’s
agent and attorney-in-fact, to direct any transferee under any sublease, license or other occupancy agreement to make all payments
under such agreement directly to Landlord (which Landlord shall apply towards Tenant’s obligations hereunder) until such
Default is cured. Such transferee shall rely upon any representation by Landlord that Tenant is in Default, whether or not confirmed
by Tenant.

 

14.8    Permitted
Transfers. Notwithstanding any contrary provision hereof, if Tenant is not in Default, Tenant
may, without Landlord’s consent pursuant to Section 14.1, assign this Lease to (a) an Affiliate of Tenant (other than
pursuant to a merger or consolidation), (b) a successor to Tenant by merger or consolidation, or (c) a successor to Tenant by purchase
of all or substantially all of Tenant’s assets (a “Permitted Transfer”),
provided that (i) at least 10 business days before the Transfer, Tenant notifies Landlord of such Transfer and delivers to Landlord
any documents or information reasonably requested by Landlord relating thereto, including reasonable documentation that the Transfer
satisfies the requirements of this Section 14.8; (ii) in the case of an assignment pursuant to clause (a) or (c) above,
the assignee executes and delivers to Landlord, at least 10 business days before the assignment, a commercially reasonable instrument
pursuant to which the assignee assumes, for Landlord’s benefit, all of Tenant’s obligations hereunder; (iii) in the
case of an assignment pursuant to clause (b) above, (A) the successor entity has a net worth (as determined in accordance with
GAAP, but excluding intellectual property and any other intangible assets (“Net Worth”))
immediately after the Transfer that is not less than the Net Worth of Tenant immediately before the Transfer, and (B) if Tenant
is a closely held professional service firm, at least 75% of its equity owners existing 12 months before the Transfer are also
equity owners of the successor entity; (iv) the transferee is qualified to conduct business in the State of California; and (v)
the Transfer is made for a good faith operating business purpose and not in order to evade the requirements of this Section
14. As used herein, “Affiliate” means, with respect to any party, a person
or entity that controls, is under common control with, or is controlled by such party.

 

15      SURRENDER.
Upon the expiration or earlier termination hereof, and subject to Sections 8 and 11 and this Section 15, Tenant
shall surrender possession of the Premises to Landlord in as good condition and repair as existed when Tenant took possession and
as thereafter improved by Landlord and/or Tenant, except for reasonable wear and tear and repairs that are Landlord’s express
responsibility hereunder. Before such expiration or termination, Tenant, without expense to Landlord, shall (a) remove from the
Premises all debris and rubbish and all furniture, equipment, trade fixtures, Lines, free-standing cabinet work, movable partitions
and other articles of personal property that are owned or placed in the Premises by Tenant or any party claiming by, through or
under Tenant (except for any Lines not required to be removed under Section 23), and (b) repair all damage to the Premises
and Building resulting from such removal. If Tenant fails to timely perform such removal and repair, Landlord may do so at Tenant’s
expense (including storage costs). If Tenant fails to remove such property from the Premises, or from storage, within 30 days after
notice from Landlord, any part of such property shall be deemed, at Landlord’s option, either (x) conveyed to Landlord without
compensation, or (y) abandoned.

 

16      HOLDOVER.
If Tenant fails to surrender the Premises upon the expiration or earlier termination hereof,
Tenant’s tenancy shall be subject to the terms and conditions hereof; provided, however, that such tenancy shall be a tenancy
at sufferance only, for the entire Premises, and Tenant shall pay Monthly Rent (on a per-month basis without reduction for any
partial month) at a rate equal to 150% of
the Monthly Rent applicable during the last calendar month of the Term.
Nothing in this Section 16 shall limit Landlord’s rights or remedies or be deemed a consent to any holdover. If Landlord
is unable to deliver possession of the Premises to a new tenant or to perform improvements for a new tenant as a result of Tenant’s
holdover, Tenant shall be liable for all resulting damages, including lost profits, incurred by Landlord.

 

    	14

    	 

    

 

17      SUBORDINATION;
ESTOPPEL CERTIFICATES. This Lease shall be subject and subordinate to all existing and future
ground or underlying leases, mortgages, trust deeds and other encumbrances against the Building or Project, all renewals, extensions,
modifications, consolidations and replacements thereof (each, a “Security Agreement”),
and all advances made upon the security of such mortgages or trust deeds, unless in each case the holder of such Security Agreement
(each, a “Security Holder”) requires in writing that this Lease be superior
thereto. Upon any termination or foreclosure (or any delivery of a deed in lieu of foreclosure) of any Security Agreement, Tenant,
upon request, shall attorn, without deduction or set-off, to the Security Holder or purchaser or any successor thereto and shall
recognize such party as the lessor hereunder provided that such party agrees not to disturb Tenant’s occupancy so long as
Tenant timely pays the Rent and otherwise performs its obligations hereunder. Within 10 days after request by Landlord, Tenant
shall execute such further instruments as Landlord may reasonably deem necessary to evidence the subordination or superiority of
this Lease to any Security Agreement. Tenant waives any right it may have under Law to terminate or otherwise adversely affect
this Lease or Tenant’s obligations hereunder upon a foreclosure. Within 10 business days after Landlord’s request,
Tenant shall execute and deliver to Landlord a commercially reasonable estoppel certificate in favor of such parties as Landlord
may reasonably designate, including current and prospective Security Holders and prospective purchasers.

 

18      ENTRY
BY LANDLORD. At all reasonable times and upon 24
hours prior notice to Tenant, or in an emergency
without the need for prior notice, Landlord may enter the Premises
to (i) inspect the Premises; (ii) show the Premises to prospective purchasers, current or prospective Security Holders or insurers,
or, during the last 12 months of the Term (or while an uncured Default exists), prospective tenants; (iii) post notices of non-responsibility;
or (iv) perform maintenance, repairs or alterations. At any time and without notice to Tenant, Landlord may enter the Premises
to perform required services. If reasonably necessary, Landlord may temporarily close any portion of the Premises to perform maintenance,
repairs or alterations. In an emergency, Landlord may use any means it deems proper to open doors to and in the Premises. No entry
into or closure of any portion of the Premises pursuant to this Section 18 shall render Landlord liable to Tenant, constitute
a constructive eviction, or excuse Tenant from any obligation hereunder.

 

19      DEFAULTS;
REMEDIES.

 

19.1    Events
of Default. The occurrence of any of the following shall constitute a “Default”:

 

19.1.1   Any
failure by Tenant to pay any Rent when due unless such failure is cured within five (5) business days after notice; or

 

19.1.2   Except
where a specific time period is otherwise set forth for Tenant’s cure herein (in which event Tenant’s failure to cure
within such time period shall be a Default), and except as otherwise provided in this Section 19.1, any breach by Tenant
of any other provision hereof where such breach continues for 30 days after notice from Landlord; provided that if such breach
cannot reasonably be cured within such 30-day period, Tenant shall not be in Default as a result of such breach if Tenant diligently
commences such cure within such period, thereafter diligently pursues such cure, and completes such cure within 60 days after Landlord’s
notice; or

 

19.1.3   Abandonment
or vacation of all or a substantial portion of the Premises by Tenant; or

 

19.1.4   Any
breach by Tenant of Sections 5, 14, 17 or 18 where such breach continues for more than two (2) business
days after notice from Landlord; or

 

19.1.5   Tenant
becomes in breach of Section 25.3.

 

If Tenant breaches
a particular provision hereof (other than a provision requiring payment of Rent) on three (3) separate occasions during any 12-month
period, Tenant’s subsequent breach of such provision shall be, at Landlord’s option, an incurable Default. The notice
periods provided herein are in lieu of, and not in addition to, any notice periods provided by Law, and Landlord shall not be required
to give any additional notice in order to be entitled to commence an unlawful detainer proceeding.

 

19.2    Remedies
Upon Default. Upon any Default, Landlord shall have, in addition to any other remedies available
to Landlord at law or in equity (which shall be cumulative and nonexclusive), the option to pursue any one or more of the following
remedies (which shall be cumulative and nonexclusive) without any notice or demand:

 

19.2.1   Landlord
may terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do
so, Landlord may, without prejudice to any other remedy it may have for possession or arrearages in Rent, enter upon and take possession
of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without
being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

 

    	15

    	 

    

 

(a)          The
worth at the time of award of the unpaid Rent which has been earned at the time of such termination; plus

 

(b)          The
worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time
of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

 

(c)          The
worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the
amount of such Rent loss that Tenant proves could have been reasonably avoided; plus

 

(d)          Any
other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its
obligations hereunder or which in the ordinary course of things would be likely to result therefrom, including brokerage commissions,
advertising expenses, expenses of remodeling any portion of the Premises for a new tenant (whether for the same or a different
use), and any special concessions made to obtain a new tenant; plus

 

(e)          At
Landlord’s option, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by
Law.

 

As used in Sections
19.2.1(a) and (b), the “worth at the time of award” shall be computed by allowing interest at a rate
per annum equal to the lesser of (i) the annual “Bank Prime Loan” rate cited in the Federal Reserve Statistical Release
Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord shall
reasonably designate if such rate ceases to be published) plus two (2) percentage points, or (ii) the highest rate permitted by
Law. As used in Section 19.2.1(c), the “worth at the time of award” shall be computed by discounting
such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus 1%.

 

19.2.2   Landlord
shall have the remedy described in California Civil Code § 1951.4 (lessor may continue lease in effect after lessee’s
breach and abandonment and recover Rent as it becomes due, if lessee has the right to sublet or assign, subject only to reasonable
limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may,
from time to time, without terminating this Lease, enforce all of its rights and remedies hereunder, including the right to recover
all Rent as it becomes due.

 

19.2.3   Landlord
shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those
rights and remedies available under Sections 19.2.1 and 19.2.2, or any Law or other provision hereof), without prior
demand or notice except as required by Law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce
this Lease, or restrain or enjoin a violation or breach of any provision hereof.

 

19.3    Efforts
to Relet. Unless Landlord provides Tenant with express notice to the contrary, no re-entry,
repossession, repair, maintenance, change, alteration, addition, reletting, appointment of a receiver or other action or omission
by Landlord shall (a) be construed as an election by Landlord to terminate this Lease or Tenant’s right to possession, or
to accept a surrender of the Premises, or (b) operate to release Tenant from any of its obligations hereunder. Tenant waives, for
Tenant and for all those claiming by, through or under Tenant, California Civil Code § 3275 and California Code of Civil Procedure
§§ 1174(c) and 1179 and any existing or future rights to redeem or reinstate, by order or judgment of any court or by
any legal process or writ, this Lease or Tenant’s right of occupancy of the Premises after any termination hereof.

 

19.4    Landlord
Default. Landlord shall not be in default hereunder unless it fails to begin within 30 days
after notice from Tenant, or fails to pursue with reasonable diligence thereafter, the cure of any breach by Landlord of its obligations
hereunder. Before exercising any remedies for a default by Landlord, Tenant shall give notice and a reasonable time to cure to
any Security Holder of which Tenant has been notified.

 

20      LANDLORD
EXCULPATION. Notwithstanding any contrary provision hereof, (a) the liability of the Landlord
Parties to Tenant shall be limited to an amount equal to the lesser of (i) Landlord’s interest in the Building, or (ii) the
equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an amount equal to 80%
of the value of the Building (as such value is determined by Landlord); (b) Tenant shall look solely to Landlord’s interest
in the Building for the recovery of any judgment or award against any Landlord Party; (c) no Landlord Party shall have any personal
liability for any judgment or deficiency, and Tenant waives and releases such personal liability on behalf of itself and all parties
claiming by, through or under Tenant; and (d) no Landlord Party shall be liable for any injury or damage to, or interference with,
Tenant’s business, including loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill
or loss of use, or for any form of special or consequential damage.

 

    	16

    	 

    

 

21      SECURITY
DEPOSIT. Concurrently with its execution and delivery hereof, Tenant shall deposit with Landlord
the Security Deposit, if any, as security for Tenant’s performance of its obligations hereunder. If Tenant breaches any provision
hereof, Landlord may, at its option, without notice to Tenant, apply all or part of the Security Deposit to pay any past-due Rent,
cure any breach by Tenant, or compensate Landlord for any other loss or damage caused by such breach. If Landlord so applies any
portion of the Security Deposit, Tenant, within three (3) days after demand therefor, shall restore the Security Deposit to its
original amount. The Security Deposit is not an advance payment of Rent or measure of damages. Any unapplied portion of the Security
Deposit shall be returned to Tenant within 60 days after the latest to occur of (a) the expiration of the Term, (b) Tenant’s
surrender of the Premises as required hereunder, or (c) determination of the final Rent due from Tenant. Landlord shall not be
required to keep the Security Deposit separate from its other accounts. 

 

Provided
no Default has occurred hereunder prior to: (a) December 31, 2013, Landlord shall reduce the Security Deposit effective as of
January 1, 2014 by an amount equal to $15,635.00, which sum shall be applied as a credit
against Base Rent for January, 2014, (b) December 31, 2014, Landlord shall reduce the Security Deposit effective as of January
1, 2015 by an amount equal to $16,104.05, which sum shall be applied as a credit against
Base Rent for January, 2015, (c) December 31, 2015, Landlord shall reduce the Security Deposit effective as of January 1, 2016
by an amount equal to $16,573.42, which sum shall be applied as a credit against Base
Rent for January, 2016, and (d) December 31, 2016, Landlord shall reduce the Security Deposit effective as of January 1, 2017
by an amount equal to $17,073.42, which sum shall be applied as a credit against Base
Rent for January, 2017. If Tenant has been in Default under the Lease at any time prior
to the effective date of any reduction of the Security Deposit and Tenant has failed to cure such Default within any applicable
cure period, then Tenant shall have no further right to reduce the amount of the Security Deposit as described herein.

 

22     RELOCATION.
Landlord, after giving no less
than 60 days prior notice, may move Tenant to other space in the Project
comparable in size and utility to the Premises, provided that the
new space shall be located within the mid-rise or hi-rise elevator banks of the Building. The new space must contain similar finishes
(subject to commercial availability) and approximately the same rentable square footage as the Premises and the same number of
work stations, offices, breakrooms and reception areas as are contained in the Premises as of the date Tenant receives Landlord’s
notice of relocation. In such event, all terms hereof shall apply to the new space, except that Base Rent and Tenant’s
Share shall not increase as a result of such relocation. Landlord, at its expense, shall provide Tenant with tenant improvements
in the new space at least equal in quality to those in the Premises. Landlord shall reimburse Tenant for Tenant’s reasonable
moving, re-cabling and stationery-replacement costs. The parties shall execute a written agreement prepared by Landlord memorializing
the relocation. Notwithstanding the foregoing, if Landlord provides
Tenant with a notice of relocation and Tenant, in its reasonable judgment, determines that the new space is not of reasonably
comparable size and utility when compared to the Premises, Tenant shall have the right to terminate this Lease by giving written
notice of termination to Landlord within 10 days after the date of Landlord's notice of relocation to Tenant. Tenant’s notice
of termination shall set forth the reasons why Tenant believes the new space is not comparable to the Premises. Such termination
shall be effective 60 days after the date of Landlord's notice of relocation, provided that Landlord, within 10 days after receipt
of Tenant's notice of termination, shall have the right to withdraw its notice of relocation. In such event, this Lease shall
continue in full force and effect as if Landlord had never provided Tenant with a notice of relocation.

 

23      COMMUNICATIONS
AND COMPUTER LINES. All Lines installed pursuant to this Lease shall
be (a) installed in accordance with Section 7; and (b) clearly marked with adhesive plastic labels (or plastic tags attached
to such Lines with wire) to show Tenant’s name, suite number, and the purpose of such Lines (i) every six (6) feet outside
the Premises (including the electrical room risers and any Common Areas), and (ii) at their termination points. Landlord
may designate specific contractors for work relating to vertical Lines. Sufficient spare cables and space for additional cables
shall be maintained for other occupants, as reasonably determined by Landlord. Unless otherwise notified by Landlord, Tenant, at
its expense and before the expiration or earlier termination hereof, shall remove all Lines and repair any resulting damage. As
used herein, “Lines” means all communications or computer wires and cables
serving the Premises, whenever and by whomever installed or paid for, including any such wires
or cables installed pursuant to any prior lease.

 

    	17

    	 

    

 

24      PARKING.
Tenant may park in the Building’s parking facilities (the “Parking Facility”),
in common with other tenants of the Building, upon the following terms and conditions. Tenant shall not use more than the number
of unreserved and/or reserved parking spaces set forth in Section 1.9. Tenant shall pay Landlord, in accordance with Section
3, any fees for the parking spaces described in Section 1.9. Tenant shall pay Landlord any fees, taxes or other charges
imposed by any governmental or quasi-governmental agency in connection with the Parking Facility, to the extent such amounts are
allocated to Tenant by Landlord. Landlord shall not be liable to Tenant, nor shall this Lease be affected, if any parking is impaired
by (or any parking charges are imposed as a result of) any Law. Tenant shall comply with all rules and regulations established
by Landlord from time to time for the orderly operation and use of the Parking Facility, including any sticker or other identification
system and the prohibition of vehicle repair and maintenance activities in the Parking Facility. Landlord may, in its discretion,
allocate and assign parking passes among Tenant and the other tenants in the Building. Tenant’s use of the Parking Facility
shall be at Tenant’s sole risk, and Landlord shall have no liability for any personal injury or damage to or theft of any
vehicles or other property occurring in the Parking Facility or otherwise in connection with any use of the Parking Facility by
Tenant or its employees or invitees. Landlord may alter the size, configuration, design, layout or any other aspect of the Parking
Facility, and, in connection therewith, temporarily deny or restrict access to the Parking Facility, in each case without abatement
of Rent or liability to Tenant. Landlord may delegate its responsibilities hereunder to a parking operator, in which case (i) such
parking operator shall have all the rights of control reserved herein by Landlord, (ii) Tenant shall enter into a parking agreement
with such parking operator, (iii) Tenant shall pay such parking operator, rather than Landlord, any charge established hereunder
for the parking spaces, and (iv) Landlord shall have no liability for claims arising through acts or omissions of such parking
operator except to the extent caused by Landlord’s gross negligence or willful misconduct. Tenant’s parking rights
under this Section 24 are solely for the benefit of Tenant’s employees and invitees and such rights may not be transferred
without Landlord’s prior consent, except pursuant to a Transfer permitted under Section 14.

25.10  Interpretation.
As used herein, the capitalized term “Section” refers to a section hereof unless otherwise specifically provided herein.
As used in this Lease, the terms “herein,” “hereof,” “hereto” and “hereunder” refer
to this Lease and the term “include” and its derivatives are not limiting. Any reference herein to “any part”
or “any portion” of the Premises, the Property or any other property shall be construed to refer to all or any part
of such property. Wherever this Lease requires Tenant to comply with any Law, rule, regulation, procedure or other requirement
or prohibits Tenant from engaging in any particular conduct, this Lease shall be deemed also to require Tenant to cause each of
its employees, licensees, invitees and subtenants, and any other party claiming by, through or under Tenant, to comply with such
requirement or refrain from engaging in such conduct, as the case may be. Wherever this Lease requires Landlord to provide a customary
service or to act in a reasonable manner (whether in incurring an expense, establishing a rule or regulation, providing an approval
or consent, or performing any other act), this Lease shall be deemed also to provide that whether such service is customary or
such conduct is reasonable shall be determined by reference to the practices of owners of buildings that (i) are comparable to
the Building in size, age, class, quality and location, and (ii) at Landlord’s option, have been, or are being prepared to
be, certified under the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) rating system
or a similar rating system. Tenant waives the benefit of any rule that a written agreement shall be construed against the drafting
party.

 

25.11  Entire
Agreement. This Lease sets forth the entire agreement between the parties relating to the
subject matter hereof and supersedes any previous agreements (none of which shall be used to interpret this Lease). Tenant acknowledges
that in entering into this Lease it has not relied upon any representation, warranty or statement, whether oral or written, not
expressly set forth herein. This Lease can be modified only by a written agreement signed by both parties.

 

25.12  Other.
Landlord, at its option, may cure any Default, without waiving any right or remedy or releasing Tenant from any obligation, in
which event Tenant shall pay Landlord, upon demand, the cost of such cure. If any provision hereof is void or unenforceable, no
other provision shall be affected. Submission of this instrument for examination or signature by Tenant does not constitute an
option or offer to lease, and this instrument is not binding until it has been executed and delivered by both parties. If Tenant
is comprised of two or more parties, their obligations shall be joint and several. Time is of the essence with respect to the performance
of every provision hereof in which time of performance is a factor. So long as Tenant performs its obligations hereunder, Tenant
shall have peaceful and quiet possession of the Premises against any party claiming by, through or under Landlord, subject to the
terms hereof. Landlord may transfer its interest herein, in which event Landlord shall be released from, Tenant shall look solely
to the transferee for the performance of, and the transferee shall be deemed to have assumed, all of Landlord’s obligations
arising hereunder after the date of such transfer (including the return of any Security Deposit) and Tenant shall attorn to the
transferee. Landlord reserves all rights not expressly granted to Tenant hereunder, including the right to make alterations to
the Project. No rights to any view or to light or air over any property are granted to Tenant hereunder. The expiration or termination
hereof shall not relieve either party of any obligation that accrued before, or continues to accrue after, such expiration or termination.
Tenant acknowledges that chilled and heated water necessary to the operation of the heating, ventilating and air conditioning system
in the Building is supplied to Landlord by a third party (the "Provider"). Landlord agrees to use reasonable, good faith
efforts to cause such provider to provide such chilled and heated water to the Building. Tenant acknowledges and agrees that the
failure of provider to supply any such services shall not have any effect on this Lease or give to Tenant any offset or defense
to the full and timely performance of its obligations hereunder or entitle Tenant to any abatement of Base Rent, Additional Rent
or any other payment required to be made by Tenant hereunder, or constitute any actual or constructive eviction of Tenant or otherwise
give rise to any other claim of any nature against Landlord.

RULES AND REGULATIONS

 

Tenant shall comply
with the following rules and regulations (as modified or supplemented from time to time, the “Rules and Regulations”).

be furnished by Landlord for the Premises, and any additional keys required by Tenant must be obtained from Landlord at a reasonable
cost to be established by Landlord. Upon the termination of this Lease, Tenant shall restore to Landlord all keys of stores, offices

doors opening to public corridors shall be kept closed at all times except for normal ingress and egress to the Premises.

 

3.          Landlord
may close and keep locked all entrance and exit doors of the Building during such hours as are customary for comparable buildings
in the vicinity of the Building. Tenant shall cause its employees, agents, contractors, invitees and licensees who use Building
doors during such hours to securely close and lock them after such use. Any person entering or leaving the Building during such
hours, or when the Building doors are otherwise locked, may be required to sign the Building register, and access to the Building
may be refused unless such person has proper identification or has a previously arranged access pass. Landlord will furnish passes
to persons for whom Tenant requests them. Tenant shall be responsible for all persons for whom Tenant requests passes and shall
be liable to Landlord for all acts of such persons. Landlord and its agents shall not be liable for damages for any error with
regard to the admission or exclusion of any person to or from the Building. In case of invasion, mob, riot, public excitement or
other commotion, Landlord may prevent access to the Building or the Project during the continuance thereof by any means it deems
appropriate for the safety and protection of life and property.

 

4.          No
furniture, freight or equipment shall be brought into the Building without prior notice to Landlord. All moving activity into or
out of the Building shall be scheduled with Landlord and done only at such time and in such manner as Landlord designates. Landlord
may prescribe the weight, size and position of all safes and other heavy property brought into the Building and also the times
and manner of moving the same in and out of the Building. Safes and other heavy objects shall, if considered necessary by Landlord,
stand on supports of such thickness as is necessary to properly distribute the weight. Landlord will not be responsible for loss
of or damage to any such safe or property. Any damage to the Building, its contents, occupants or invitees resulting from Tenant’s
moving or maintaining any such safe or other heavy property shall be the sole responsibility and expense of Tenant (notwithstanding
Sections 7 and 10.4 of this Lease).

 

5.          No
furniture, packages, supplies, equipment or merchandise will be received in the Building or carried up or down in the elevators,

bear the expense of any breakage, stoppage or damage resulting from any violation of this rule by Tenant or any of its employees,
agents, contractors, invitees or licensees.

consent.

 

11.         Tenant
shall not, without Landlord’s prior consent, use, store, install, disturb, spill, remove, release or dispose of, within or
about the Premises or any other portion of the Project, any asbestos-containing materials, any solid, liquid or gaseous material
now or subsequently considered toxic or hazardous under the provisions of 42 U.S.C. Section 9601 et seq. or any other applicable
environmental Law, or any inflammable, explosive or dangerous fluid or substance; provided, however, that Tenant may use, store
and dispose of such substances in such amounts as are typically found in similar premises used for general office purposes provided
that such use, storage and disposal does not damage any part of the Premises, Building or Project and is performed in a safe manner
and in accordance with all Laws. Tenant shall comply with all Laws pertaining to and governing the use of such materials by Tenant
and shall remain solely liable for the costs of abatement and removal. No burning candle or other open flame shall be ignited or

occupants or those having business therein, whether by the use of any musical instrument, radio, CD player or otherwise. Tenant

for employees and invitees, provided that such use complies with all Laws.

 

16.         The
Premises shall not be used for manufacturing or for the storage of merchandise except to the extent such storage may be incidental
to the Permitted Use. Tenant shall not occupy the Premises as an office for a messenger-type operation or dispatch office, public
stenographer or typist, or for the manufacture or sale of liquor, narcotics or tobacco, or as a medical office, a barber or manicure
shop, or an employment bureau, without Landlord’s prior consent. Tenant shall not engage or pay any employees in the Premises
except those actually working for Tenant in the Premises, nor advertise for laborers giving an address at the Premises.

 

17.         Landlord
may exclude from the Project any person who, in Landlord’s judgment, is intoxicated or under the influence of liquor or drugs,
or who violates any of these Rules and Regulations.

the Building. All trash, garbage and refuse disposal shall be made only through entryways and elevators provided for such purposes
at such times as Landlord shall designate. Tenant shall comply with Landlord’s recycling program, if any.

 

21.         Tenant

22.         Any
persons employed by Tenant to do janitorial work shall be subject to Landlord’s prior consent and, while in the Building
and outside of the Premises, shall be subject to the control and direction of the Building manager (but not as an agent or employee

for the management, safety, care and cleanliness of the Premises, the Building, the Common Areas and the Project, for the preservation
of good order therein, and for the convenience of other occupants and tenants thereof. Landlord may waive any of these Rules and
Regulations for the benefit of any tenant, but no such waiver shall be construed as a waiver of such Rule and Regulation in favor
of any other tenant nor prevent Landlord from thereafter enforcing such Rule and Regulation against any tenant.

JUDICIAL REFERENCE

 

IF
THE JURY-WAIVER PROVISIONS OF SECTION 25.8 OF THIS LEASE ARE NOT ENFORCEABLE UNDER CALIFORNIA LAW, THE PROVISIONS SET FORTH

It
is the desire and intention of the parties to agree upon a mechanism and procedure under which controversies and disputes arising
out of this Lease or related to the Premises will be resolved in a prompt and expeditious manner. Accordingly, except with respect

counterclaim brought by either party hereto against the other (and/or against its officers, directors, employees, agents or subsidiaries
or affiliated entities) on any matters arising out of or in any way connected with this Lease, Tenant’s use or occupancy
of the Premises and/or any claim of injury or damage, whether sounding in contract, tort, or otherwise, shall be heard and resolved
by a referee under the provisions of the California Code of Civil Procedure, Sections 638 — 645.1, inclusive (as same may
be amended, or any successor statute(s) thereto) (the “Referee Sections”).
Any fee to initiate the judicial reference proceedings and all fees charged and costs incurred by the referee shall be paid by
the party initiating such procedure (except that if a reporter is requested by either party, then a reporter shall be present at
all proceedings where requested and the fees of such reporter – except for copies ordered by the other parties – shall
be borne by the party requesting the reporter); provided however, that allocation of the costs and fees, including any initiation
fee, of such proceeding shall be ultimately determined in accordance with Section 25.6 of this Lease. The venue of the proceedings
shall be in the county in which the Premises are located. Within 10 days of receipt by any party of a request to resolve any dispute
or controversy pursuant to this Exhibit E, the parties shall agree upon a single
referee who shall try all issues, whether of fact or law, and report a finding and judgment on such issues as required by the Referee
Sections. If the parties are unable to agree upon a referee within such 10-day period, then any party may thereafter file a lawsuit
in the county in which the Premises are located for the purpose of appointment of a referee under the Referee Sections. If the
referee is appointed by the court, the referee shall be a neutral and impartial retired judge with substantial experience in the
relevant matters to be determined, from Jams/Endispute, Inc., ADR Services, Inc. or a similar mediation/arbitration entity approved
by each party in its sole and absolute discretion. The proposed referee may be challenged by any party for any of the grounds listed
in the Referee Sections. The referee shall have the power to decide all issues of fact and law and report his or her decision on
such issues, and to issue all recognized remedies available at law or in equity for any cause of action that is before the referee,
including an award of attorneys’ fees and costs in accordance with this Lease. The referee shall not, however, have the power
to award punitive damages, nor any other damages that are not permitted by the express provisions of this Lease, and the parties
waive any right to recover any such damages. The parties may conduct all discovery as provided in the California Code of Civil
Procedure, and the referee shall oversee discovery and may enforce all discovery orders in the same manner as any trial court judge,
with rights to regulate discovery and to issue and enforce subpoenas, protective orders and other limitations on discovery available
under California Law. The reference proceeding shall be conducted in accordance with California Law (including the rules of evidence),
and in all regards, the referee shall follow California Law applicable at the time of the reference proceeding. The parties shall
promptly and diligently cooperate with one another and the referee, and shall perform such acts as may be necessary to obtain a
prompt and expeditious resolution of the dispute or controversy in accordance with the terms of this Exhibit E.
In this regard, the parties agree that the parties and the referee shall use best efforts to ensure that (a) discovery be conducted
for a period no longer than six (6) months from the date the referee is appointed, excluding motions regarding discovery, and (b)
a trial date be set within 9 months of the date the referee is appointed. In accordance with Section 644 of the California Code
of Civil Procedure, the decision of the referee upon the whole issue must stand as the decision of the court, and upon the filing
of the statement of decision with the clerk of the court, or with the judge if there is no clerk, judgment may be entered thereon
in the same manner as if the action had been tried by the court. Any decision of the referee and/or judgment or other order entered
thereon shall be appealable to the same extent and in the same manner that such decision, judgment, or order would be appealable
if rendered by a judge of the superior court in which venue is proper hereunder. The referee shall in his/her statement of decision
set forth his/her findings of fact and conclusions of law. The parties intend this general reference agreement to be specifically
enforceable in accordance with the Code of Civil Procedure. Nothing in this Exhibit E
shall prejudice the right of any party to obtain provisional relief or other equitable remedies from a court of competent jurisdiction
as shall otherwise be available under the Code of Civil Procedure and/or applicable court rules.
