pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Securities except in compliance with the Securities Act and the rules and regulations promulgated thereunder.

 4.4 Reliance on Exemptions; Registration or Exemption Requirements. Purchaser understands that the Shares being
offered and sold to it in reliance on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Purchaser’s
compliance with, the representations, warranties, agreements, acknowledgements and understandings of such Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the
Shares. Purchaser further acknowledges and understands that the Securities may not be resold or otherwise transferred

except in a transaction registered under the Securities Act or unless an exemption from such registration is available. 
 4.5 Dispositions. 
 (a) Purchaser will not, prior to the
effectiveness of the Registration Statement, if then prohibited by law or regulation: (i) sell, offer to sell, solicit offers to buy, dispose of, loan, pledge or grant any right with respect to (collectively, a
“Disposition”) the Securities; or (ii) engage in any hedging or other transaction which is designed or could reasonably be expected to lead to or result in a Disposition of Securities by such Purchaser or an affiliate.

 (b) Purchaser has not directly or indirectly, nor has any Person (as defined below) acting on behalf of or pursuant to
any understanding with such Purchaser, engaged in any transactions in the Company’s securities (including, without limitation, any Short Sales (as defined below) involving the Company’s securities) since the time that such Purchaser was
first contacted by the Company or any other Person regarding the transactions contemplated hereby. Such Purchaser covenants that neither it nor any Person acting on its behalf or pursuant to any understanding with it will engage in any transactions
in the Company’s securities (including, without limitation, any Short Sales involving the Company’s securities) prior to the time that the transactions contemplated by this Agreement are publicly disclosed. 

For purposes of this Section 4.5(b), (i) “Person” shall include, without limitation, any individual or
corporation, partnership, trust, incorporated or unincorporated association, joint venture, limited liability company or joint stock company and (ii) “Short Sales” shall include, without limitation, all “short
sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act and all types of direct and indirect stock pledges, forward sale contracts, options, puts, calls, short sales, swaps and similar arrangements (including on a
total return basis), and sales and other transactions through non-U.S. broker-dealers or foreign regulated brokers. 
 4.6 No
Legal, Tax or Investment Advice. Purchaser has independently evaluated the merits of its decision to purchase Shares pursuant to this Agreement, and such Purchaser confirms that it has not relied on the advice of any other Purchaser’s
business and/or legal counsel in making such decision. Purchaser understands that nothing in this Agreement or any other materials presented to Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment
advice. Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Shares. 

4.7 Confidentiality. Purchaser will hold in confidence all information concerning this Agreement and the placement of the Shares
hereunder until the earlier of such time as (a) the Company has made a public announcement concerning the Agreement and the placement of the Shares hereunder, (b) this Agreement is terminated or (c) five trading days after the date of
this Agreement. 

  
 13.









 4.8 Residency. Purchaser’s executive offices in which its investment decision
was made are in the jurisdiction indicated below such Purchaser’s name on the applicable signature page hereto. 
 4.9
Governmental Review. Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed upon or made any recommendation or endorsement of the Securities. 

4.10 Legend. 
 (a) Purchaser understands that, until such time as the requirements set forth in Section 4.10(b) have been satisfied, or the Securities have been registered under the Securities Act or
otherwise may be sold pursuant to Rule 144, the Securities shall bear a restrictive legend in substantially the following form (and a stop transfer order may be placed against transfer of the certificates for the Securities): 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR IN ANY OTHER JURISDICTION. THE SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR TRANSFERRED PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS.” 
 (b) The Company agrees that it will, no later than three business days following the sale by a Purchaser of Securities pursuant to a Registration Statement (as defined below) in which the
prospectus delivery requirements set forth in Section 4.10(c)(i) have been satisfied or the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing Securities issued with a restrictive legend
and a signed and completed certificate of sale in substantially the form of Exhibit C attached hereto, deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from any legend referring to the
Securities Act. The Company shall not make any notation on its records or give instructions to any transfer agent of the Company that enlarge the restrictions on transfer set forth in this Section. Certificates for Securities subject to legend
removal hereunder may, at the Company’s option, be transmitted by the transfer agent of the Company to the Purchasers by crediting the account of the Purchaser’s prime broker with the Depository Trust Company. All costs and expenses
related to the removal of the legends and the reissuance of any Securities shall be borne by the Company. 

  
 14.









 (c) Each Purchaser, severally and not jointly with the other Purchasers, agrees that
the removal of the restrictive legend from certificates representing Securities as set forth in this Section 4.10 is predicated upon the Company’s reliance that the Purchaser will sell any Securities pursuant to either (i) the
registration requirements of the Securities Act and such Purchaser shall have delivered a current prospectus in connection with such sale or such Purchaser shall have confirmed that a current prospectus is deemed to be delivered in connection with
such sale in accordance with Rule 172 under the Securities Act (“Rule 172”) or (ii) an exemption therefrom. 
 4.11 Foreign Investors. If Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), Purchaser hereby represents that it has
satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Shares or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase
of the Shares, (b) any foreign exchange restrictions applicable to such purchase or acquisition, (c) any government or other consents that may need to be obtained, and (d) the income tax and other tax consequences, if any, that may be
relevant to the purchase, holding, redemption, sale or transfer of the Shares. Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of
Purchaser’s jurisdiction.

COVENANTS 
 7.1 Definitions. For the purpose of this Article 7: 
 (a) the
term “Registration Statement” shall mean any registration statement required to be filed by Section 7.2 below, and shall include any preliminary prospectus, final prospectus, exhibit or amendment included in or relating
to such registration statements; and 
 (b) the term “Registrable Shares” means all Conversion
Shares and up to 900,000 Dividend Shares; provided, however, that a security shall cease to be a Registrable Share upon the earliest to occur of the following: (i) a Registration Statement registering such security under the Securities
Act has been declared or becomes effective and such security has been sold or otherwise transferred by the holder thereof pursuant to and in a manner contemplated by such effective Registration Statement, (ii) such security is sold pursuant to
Rule 144 under circumstances in which any legend borne by such security relating to restrictions on 

  
 17.

including without any limitation as to volume of sales, and without the Holder complying with any method of sale requirements or notice requirements under Rule 144, or (iv) such security shall cease to be outstanding. 

7.2 Registration Procedures and Expenses. The Company shall: 

(a) use its best efforts to file a Registration Statement (the “Mandatory Registration Statement”) with
the SEC on or before the date 45 days following the Initial Closing Date (the “Filing Date”) to register the Registrable Shares on Form S-3 under the Securities Act (providing for shelf registration of such Registrable
Shares under SEC Rule 415) or on such other form which is appropriate to register such Registrable Shares for resale from time to time by the Purchasers; 
 (b) use its commercially reasonable efforts to cause such Mandatory Registration Statement to be declared effective as promptly as practicable following the Filing Date, such efforts to include,
without limiting the generality of the foregoing, preparing and filing with the SEC any financial statements or other information that is required to be filed prior to the effectiveness of such Mandatory Registration Statement; 

(c) notwithstanding anything contained in this Agreement to the contrary, in the event that the SEC limits the amount of
Registrable Shares or otherwise requires a reduction in the number of Registrable Shares that may be included and sold by the Purchasers in the Mandatory Registration Statement (in which case such reduction of such Registrable Shares shall first
reduce shares included in the Mandatory Registration Statement that may be issued as Dividend Shares on a pro rata basis among all the Purchasers in proportion to the respective number of Shares beneficially owned by all Purchasers and shall second
reduce Conversion Shares included in the Mandatory Registration Statement for all Purchasers on a pro rata basis in proportion to the respective number of Shares beneficially owned by all Purchasers), or for any other reason any Registrable Shares
are not then included in the Mandatory Registration Statement filed under this Agreement, then the Company shall prepare and file (i) within 10 business days of the first date or time that such excluded Registrable Shares may then be included
in a Registration Statement if the SEC shall have notified the Company that certain Registrable Shares were not eligible for inclusion in the Registration Statement or (ii) in all other cases, within 20 days following the date that the Company
becomes aware that such additional Registration Statement is required (the “Additional Filing Date”), a Registration Statement (any such Registration Statement registering such excluded Registrable Shares, an
“Additional Registration Statement” and, together with the Mandatory Registration Statement, a “Registration Statement”) to register any Registrable Shares that have been excluded (or, if applicable,
the maximum number of such excluded Registrable Shares that the Company is permitted to register for resale on such Additional Registration Statement consistent with SEC guidance), if any, from being registered on the Mandatory Registration
Statement; 

  
 18.









 (d) use its commercially reasonable efforts to cause any such Additional Registration
Statement to be declared effective as promptly as practicable following the Additional Filing Date, such efforts to include, without limiting the generality of the foregoing, preparing and filing with the SEC any financial statements or other
information that is required to be filed prior to the effectiveness of any such Additional Registration Statement; 
 (e)
prepare and file with the SEC such amendments and supplements to such Registration Statements and the prospectus used in connection therewith as may be necessary to keep such Registration Statements continuously effective and free from any
material misstatement or omission to state a material fact therein until termination of such obligation as provided in Section 7.5 below, subject to the Company’s right to suspend pursuant to Section 7.4; 

(f) furnish to each Purchaser (and to each underwriter, if any, of such Registrable Shares) such number of copies of prospectuses
in conformity with the requirements of the Securities Act and such other documents as the Purchasers may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Registrable Shares by the Purchasers;

 (g) file such documents as may be required of the Company for normal securities law clearance for the resale of the
Registrable Shares in such states of the United States as may be reasonably requested by each Purchaser and use its commercially reasonable efforts to maintain such blue sky qualifications during the period the Company is required to maintain
effectiveness of the Registration Statements; provided, however, that the Company shall not be required in connection with this Section 7.2(g) to qualify as a foreign corporation or execute a general consent to service of process in any
jurisdiction in which it is not now so qualified or has not so consented; 
 (h) upon notification by the SEC that the
Registration Statement will not be reviewed or is not subject to further review by the SEC, the Company shall within five business days following the date of such notification request acceleration of such Registration Statement; 

(i) upon notification by the SEC that that the Registration Statement has been declared effective by the SEC, the Company shall
file the final prospectus under Rule 424 of the Securities Act (“Rule 424”) within the applicable time period prescribed by Rule 424; 
 (j) advise each Purchaser promptly: 
 (i) of the effectiveness of
the Registration Statement or any post-effective amendments thereto; 
 (ii) of any request by the SEC for amendments to
the Registration Statement or amendments to the prospectus or for additional information relating thereto; 

  
 19.









 (iii) of the issuance by the SEC of any stop order suspending the effectiveness of
the Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Registrable Shares for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the
preceding purposes; and 
 (iv) of the existence of any fact and the happening of any event that makes any statement of
a material fact made in the Registration Statement, the prospectus and amendment or supplement thereto, or any document incorporated by reference therein, untrue, or that requires the making of any additions to or changes in the Registration
Statement or the prospectus in order to make the statements therein not misleading; 
 (k) use its commercially
reasonable efforts to cause all Registrable Shares to be listed on each securities exchange, if any, on which equity securities by the Company are then listed; and 
 (l) bear all expenses in connection with the procedures in paragraphs (a) through (k) of this Section 7.2 and the registration of the Registrable Shares on such Registration
Statement and the satisfaction of the blue sky laws of such states. 
 7.3 Indemnification. 

(a) The Company agrees to indemnify and hold harmless each Purchaser, the partners, members, officers and directors of each
Purchaser and each person, if any, who controls such Purchaser within the meaning of the Securities Act or the Exchange Act, from and against any losses, claims, damages or liabilities to which they may become subject (under the Securities Act or
otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any material breach of this Agreement by the Company or any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading or arise out of any failure by the Company to fulfill any undertaking included in the Registration Statement and the Company will, as incurred, reimburse such Purchaser, partner, member, officer, director or
controlling person for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim; provided, however, that the Company shall not be liable in any such case to the
extent that such loss, claim, damage or liability (collectively, “Loss”) arises out of, or is based upon, an untrue statement or omission or alleged untrue statement or omission made in such Registration Statement in reliance
upon and in conformity with written information furnished to the Company by or on behalf of such Purchaser, partner, member, officer, director or controlling person specifically for use in preparation of the Registration Statement or any breach of
this Agreement by such Purchaser; provided further, however, that the Company shall not be liable to any Purchaser (or any partner, member, officer, director or controlling person of such Purchaser) to the extent that any such Loss is caused
by an untrue statement or omission or alleged untrue statement or omission made 

  
 20.









 
in any preliminary prospectus if either (i) (A) such Purchaser failed to send or deliver a copy of the final prospectus with or prior to, or such Purchaser failed to confirm that a
final prospectus was deemed to be delivered prior to (in accordance with Rule 172), the delivery of written confirmation of the sale by such Purchaser to the person asserting the claim from which such Loss resulted and (B) the final prospectus
corrected such untrue statement or omission, (ii) (X) such untrue statement or omission is corrected in an amendment or supplement to the prospectus and (Y) having previously been furnished by or on behalf of the Company with copies
of the prospectus as so amended or supplemented or notified by the Company that such amended or supplemented prospectus has been filed with the SEC, in accordance with Rule 172, such Purchaser thereafter fails to deliver such prospectus as so
amended or supplemented, with or prior to or such Purchaser fails to confirm that the prospectus as so amended or supplemented was deemed to be delivered prior to (in accordance with Rule 172), the delivery of written confirmation of the sale by
such Purchaser to the person asserting the claim from which such Loss resulted or (iii) such Purchaser sold Registrable Shares in violation of such Purchaser’s covenant contained in Section 7.4 of this Agreement. 

(b) Each Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Company (and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, each officer of the Company who signs the Registration Statement and each director of the Company), from and against any losses,
claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) arise out of, or are based upon, any material breach of this Agreement by such Purchaser or any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any omission or alleged
omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading in each case, on the effective date thereof, if, and to the
extent, such untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information furnished by or on behalf of such Purchaser specifically for use in preparation of the
Registration Statement, and such Purchaser will reimburse the Company (and each of its officers, directors or controlling persons) for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such
action, proceeding or claim; provided, however, that in no event shall any indemnity under this Section 7.3(b) be greater in amount than the dollar amount of the proceeds received by such Purchaser upon the sale of such Registrable
Shares. 
 (c) Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in
respect of which indemnity is to be sought against an indemnifying person pursuant to this Section 7.3, such indemnified person shall notify the indemnifying person in writing of such claim or of the commencement of such action, and, subject to
the provisions hereinafter stated, in case any such action shall be brought against an indemnified person and such indemnifying person shall have been notified thereof, such indemnifying person shall be entitled to participate therein, and, to the
extent that it shall wish, to 

  
 21.









 
assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After notice from the indemnifying person to such indemnified person of its election to assume the
defense thereof, such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection with the defense thereof; provided, however, that if there exists
or shall exist a conflict of interest that would make it inappropriate in the reasonable judgment of the indemnified person for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate
thereof, the indemnified person shall be entitled to retain its own counsel at the expense of such indemnifying person; provided, further, that no indemnifying person shall be responsible for the fees and expense of more than one separate
counsel for all indemnified parties. The indemnifying party shall not settle an action without the consent of the indemnified party, which consent shall not be unreasonably withheld. 

(d) If after proper notice of a claim or the commencement of any action against the indemnified party, the indemnifying party does
not choose to participate, then the indemnified party shall assume the defense thereof and upon written notice by the indemnified party requesting advance payment of a stated amount for its reasonable defense costs and expenses, the indemnifying
party shall advance payment for such reasonable defense costs and expenses (the “Advance Indemnification Payment”) to the indemnified party. In the event that the indemnified party’s actual defense costs and expenses
exceed the amount of the Advance Indemnification Payment, then upon written request by the indemnified party, the indemnifying party shall reimburse the indemnified party for such difference; in the event that the Advance Indemnification Payment
exceeds the indemnified party’s actual costs and expenses, the indemnified party shall promptly remit payment of such difference to the indemnifying party. 
 (e) If the indemnification provided for in this Section 7.3 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages
or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of
such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other, as well as any other relevant equitable considerations;
provided, that in no event shall any contribution by an indemnifying party hereunder be greater in amount than the dollar amount of the proceeds received by such indemnifying party upon the sale of such Registrable Shares. 

7.4 Prospectus Delivery. Each Purchaser hereby covenants with the Company not to make any sale of the Registrable Shares without
complying with Section 8.3. Each Purchaser acknowledges that there may be times when the Company must suspend the use of the prospectus forming a part of the Registration Statement until such time as an amendment to the Registration Statement
has been filed by the Company and declared effective by the SEC, or until such time as the Company has filed an appropriate report with the SEC pursuant to the Exchange Act. Each Purchaser hereby covenants that it will not sell any Registrable
Shares pursuant to said prospectus during the period commencing at the time at which the Company 

  
 22.









 
gives such Purchaser notice of the suspension of the use of said prospectus and ending at the time the Company gives such Purchaser notice that such Purchaser may thereafter effect sales pursuant
to said prospectus; provided, that such suspension periods shall in no event exceed 30 days in any 12 month period and that, in the good faith judgment of the Company’s Board of Directors, the Company would, in the absence of such delay
or suspension hereunder, be required under state or federal securities laws to disclose any corporate development, a potentially significant transaction or event involving the Company, or any negotiations, discussions, or proposals directly relating
thereto, in either case the disclosure of which would reasonably be expected to have a material adverse effect upon the Company or its stockholders; provided further, that the Company may suspend the use of the prospectus forming a part of
the Registration Statement to the extent necessary to file any post-effective amendment to the Registration Statement in order to amend the table of selling stockholders within the Registration Statement to reflect transfers of the Securities
pursuant to Sections 8.3(a) and 8.3(b). 
 7.5 Termination of Obligations. The obligations of the Company pursuant to
Section 7.2 hereof shall cease and terminate, with respect to any Registrable Shares, upon the earlier to occur of (a) such time such Registrable Shares have been resold, or (b) such time as such Registrable Shares no longer remain
Registrable Shares pursuant to Section 7.1(b) hereof. 
 7.6 Reporting Requirements. 

(a) With a view to making available the benefits of certain rules and regulations of the SEC that may at any time permit the sale
of the Securities to the public without registration or pursuant to a registration statement on Form S-3, the Company agrees to use commercially reasonable efforts to: 
 (i) make and keep public information available, as those terms are understood and defined in Rule 144; 
 (ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and 

(iii) so long as any of the Purchasers own Registrable Shares, to furnish to such Purchaser upon request (A) a written
statement by the Company as to whether it is in compliance with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, or whether it is qualified as a registrant whose securities may be resold pursuant to SEC
Form S-3, (B) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company and (C) such other information as may be reasonably requested to permit Purchasers to sell
such securities pursuant to Rule 144. 
 7.7 Blue Sky. The Company shall obtain and maintain all necessary blue sky law
permits and qualifications, or secured exemptions therefrom, required by any state for the offer and sale of Securities.

Nothing contained herein and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers
are in any way acting in concert or as a group, or are deemed affiliates (as such term is defined under the Exchange Act) with respect to such obligations or the transactions contemplated by this Agreement. Each Purchaser shall be entitled to
independently protect and enforce its rights, including without limitation the rights arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose.

 9.5 Governing Law. This Agreement shall be governed in all respects by and construed in accordance with the laws of
the State of California without any regard to conflicts of laws principles.

warranties, covenants and agreements made in this Agreement shall survive any investigation made by the Company or the Purchasers and the applicable Closing.

Upon a permitted transfer of a Purchaser’s Securities on the books of the Company in accordance with the terms of Sections 8.3(a)(iii) or 8.3(b), the Purchaser may assign this Agreement to the permitted transferee upon prior written notice to
the Company. Except as set forth in the previous sentence, no Purchaser shall assign this Agreement without the prior written consent of the Company.

writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed telex or facsimile if sent during normal business hours of the recipient, if not, then on the next business
day, (c) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written
verification of receipt. All communications shall be sent to the Company or the Purchasers, as the case may be, at their respective addresses set forth at the beginning of this Agreement or indicated below such Purchaser’s name on the
applicable signature page hereto, as appropriate, or at such other address as the Company or the Purchasers may designate by 10 days advance written notice to the other party. 

  
 26.









 9.10 Severability of this Agreement. If any provision of this Agreement shall be
judicially determined to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 

9.11 Counterparts; Facsimile. This Agreement may be executed in any number of counterparts, each of which shall be an original,
but all of which together shall constitute one instrument. Facsimile signatures shall be treated the same as original signatures. 
 9.12 Further Assurances. Each party to this Agreement shall do and perform or cause to be done and performed all such further acts and things and shall execute and deliver all such other
