C.The parties desire to amend the Lease to extend the term of the Lease as to
the 2nd Floor Premises (as defined in the Lease) and to otherwise modify the

a g r e e m e n t:

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
covenants contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
hereby agree as follows:

1.Capitalized Terms.  All capitalized terms when used herein shall have the same
meanings given such terms in the Lease unless expressly superseded by the terms
of this Amendment.  All references in the Lease and in this Amendment to “the
Lease” or “this Lease” shall be construed to mean the Lease referenced above as
amended and supplemented by this Amendment.
2.Extension of Term.  Pursuant to the Third Amendment to Lease, the Term of the
2nd Floor Premises (defined as the “Leased Premises” in the Original Lease)
shall expire on September 30, 2020 (defined as the “Initial Extension Term”).
 Pursuant to this Amendment, Landlord and Tenant agree to extend the Term of the
Lease for one (1) month from the expiration

--------------------------------------------------------------------------------

of the Initial Extension Term.  Accordingly, upon the full execution of this
Amendment, the Term of the Lease as to the 2nd Floor Premises shall expire on
October 31, 2020.
3.Condition of 2nd Floor Premises.  Tenant acknowledges that it has been
occupying the 2nd Floor Premises and, except as otherwise provided in the Lease
or this Amendment, Tenant accepts the 2nd Floor Premises in its current “AS-IS”
condition without any agreements, representations, understandings or obligations
on the part of Landlord to perform or pay for any alterations, repairs or
improvements except as provided in the Lease.  Tenant further acknowledges that
except as expressly provided in the Lease and this Amendment, neither Landlord
nor any agent of Landlord has made any representation or warranty regarding the
condition of the Premises, the improvements, refurbishments, or alterations
therein, or with respect to the functionality thereof or the suitability of any
of the foregoing for the conduct of Tenant’s business and that all
representations and warranties of Landlord, if any, are as set forth in the
Lease and this Amendment.  Please be advised that the Premises, the Building and
the Premises have not undergone inspection by a Certified Access Specialist
(CASp).  The foregoing verification is included in this Amendment solely for the
purpose of complying with California Civil Code Section 1938 and shall not in
any manner affect Landlord's and Tenant's respective responsibilities for
compliance with construction-related accessibility standards as provided under
the Lease.  Tenant hereby waives any and all rights under and benefits of
California Civil Code Section 1938 and acknowledges that the Premises, the
Building and the Project have not undergone inspection by a CASp.
4.No Brokers.  Landlord and Tenant hereby warrant to each other that they shall
have no obligation to provide a commission to any real estate broker or agent in
connection with the negotiation of this Amendment. Each party agrees to
indemnify and defend the other party against and hold the other party harmless
from any and all claims, demands, losses, liabilities, lawsuits, judgments, and
costs and expenses (including, without limitation, reasonable attorneys' fees)
with respect to any leasing commission or equivalent compensation alleged to be
owing on account of any dealings with any real estate broker or agent occurring
by, through our under the indemnifying party.
5.Authorization.  Landlord and Tenant represent and warrant to each other
respectively that they have the requisite power and authority to enter into this
Amendment; that all necessary and appropriate approvals, authorizations and
other steps have been taken to effect the legality of this Amendment; that the
signatories executing this Amendment on behalf of Landlord and Tenant have been
duly authorized and empowered to execute this Amendment on behalf of Landlord
and Tenant, respectively; and that this Amendment is valid and shall be binding
upon and enforceable against Landlord and Tenant and their respective successors
and assigns and shall inure to the benefit of Landlord and Tenant, and their
respective successors and assigns.
6.Full Force and Effect.  Except as set forth herein, all of the terms,
covenants, and conditions of the Lease shall remain in full force and effect and
there exists as of the date hereof no default or breach by Tenant of (or to
Landlord’s knowledge the occurrence of an event which, with the passage of time
or the giving of notice or either of them would constitute a default or breach
by Tenant of) any of the terms or conditions of, or obligations of Tenant under
the Lease.  If a conflict or inconsistency exists between the terms and
provisions of this Amendment and the

--------------------------------------------------------------------------------

terms and provisions of the Lease, the terms and provisions of this Amendment
shall control to the extent of any such conflict or inconsistency.
7.Submission. Submission of this Amendment by Tenant to Landlord for examination
and/or execution shall not in any manner bind Tenant and no obligations on
Tenant shall arise under this Amendment unless and until this Amendment is fully
signed and delivered by Landlord and Tenant; provided, however, the execution
and delivery by Tenant of this Amendment to Landlord shall constitute an
irrevocable offer by Tenant of the terms and conditions herein contained, which
offer may not be revoked for thirty (30) days after such delivery.
8.Counterparts; Electronic Signatures.  This Amendment may be executed in any
number of counterparts, all of which shall be deemed an original, but such
counterparts, when taken together, shall constitute one agreement.  The parties
hereto may deliver their signatures to this Amendment by electronic mail, or
other electronic transmission, and agree to accept such digital image of this
Amendment, as executed, as a true and correct original and admissible as if such
signatures were original executed versions of this Amendment.
