through the date hereof (the “Exchange Act Documents”) and is registered or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the location of the properties owned or
leased by it requires such qualification and where the failure to be so qualified would have a material adverse effect upon the condition (financial or otherwise) of the Company and its Subsidiaries, considered as one enterprise (a “Material
Adverse Effect”), and no proceeding has been instituted in any such jurisdiction, revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification.

this Agreement and each of the documents, agreements or instruments entered into in connection with the transactions contemplated by this Agreement (the “Transaction Documents”), and the Transaction Documents have been duly authorized and
validly executed and delivered by the Company and constitute legal, valid and binding agreements of the Company enforceable against the Company in accordance with their terms, except as rights to indemnity and contribution may be limited by state or

Subsidiary; or (iii) any law, administrative regulation, ordinance or order of any court or governmental agency, arbitration panel or authority applicable to the Company or any Subsidiary or their respective properties, except in the case of

Exhibit. Except for (i) the filing of a Form 8-K in connection with the transactions contemplated by the Transaction Documents, and (ii) the Registration Statement, Form D and any related state “Blue Sky” filings required to be

the Securities and Exchange Commission promulgated thereunder, and none of the Exchange Act Documents, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in

material adverse change or to have a Material Adverse Effect. 
 3.11 No Manipulation of Stock. The Company has not taken and will
not, in violation of applicable law, take, any action designed to or that might reasonably be expected to cause or result in stabilization or manipulation of the price of the Common Stock to facilitate the sale or resale of the Notes, the Warrants

this Agreement; provided, however, that in making such representation, such Purchaser does not agree to hold the Securities for any minimum or specific term and reserves the right to sell, transfer or otherwise dispose of the Securities at any time
in accordance with the provisions of this Agreement and with Federal and state securities laws applicable to such sale, transfer or disposition.

entitled to update such information by providing notice thereof to the Company before the effective date of such Registration Statement.

representations and warranties. 
 (g) As of the date hereof, in the event of the conversion of the Notes, each Purchaser would own that
number of shares of Common Stock noted in Schedule A hereto.

following: 
 (a) If the Purchaser shall propose to sell any Securities, the Purchaser shall notify the Company of its intent to do so on or
before two (2) business days prior to the date of such sale (the “Notice of Sale”), and the provision of the Notice of Sale to the Company shall conclusively be deemed to establish an agreement by such Purchaser to comply with the
registration provisions herein described. The Notice of Sale shall be deemed to constitute a representation that any information previously supplied by such Purchaser is accurate as of the date of such Notice of Sale. 
 (b) The Notice of Sale in substantially the form attached as Exhibit I to Appendix II shall be given in accordance with the provisions of
Section 4.2(a) hereof. However, the Purchaser may give the Notice of Sale orally by telephoning the current Chief Financial

speaks directly with the current Chief Financial Officer. In addition, an oral Notice of Sale shall only be deemed effective if it is followed by a written Notice of Sale received by the Company by personal delivery or facsimile within 24 hours
after giving the oral Notice of Sale. 
 (c) The Company may refuse to permit the Purchaser to resell any Securities for a period of time
not to exceed 30 days; provided, however, that in order to exercise this right, the Company must deliver a certificate in writing to the Purchaser to the effect that the Registration Statement in its then current form contains an untrue statement of
material fact or omits to state a material fact necessary in order to make the statements made therein, in light of the circumstances under which they were made, not misleading. During any suspension period (each a “Suspension”) as
contemplated by this Section 4.2(c), of which there shall be no more than two in any 12-month period, the Company will not allow any of its officers or directors to buy or sell shares of the Company’s securities. 
 4.3 Certain Trading Limitations. Each Purchaser represents and warrants that it has not directly or indirectly, nor has any person or entity

which such Purchaser entered into a confidentiality or similar agreement or understanding with the Company in connection with such Purchaser’s participation in the transactions contemplated by this Agreement. 
 4.4 Due Execution, Delivery and Performance. Each Purchaser represents and warrants that: 
 (a) This Agreement has been duly executed and delivered by the Purchaser and constitutes a valid and binding obligation of the Purchaser and the Company,
enforceable against the Purchaser in accordance with its terms. 
 (b) The execution, delivery and performance of the Transaction Documents
and the consummation of the transactions contemplated hereby and thereby and the fulfillment of the terms of the Transaction Documents have been duly authorized by all necessary corporate or LLC action and will not conflict with or constitute a
breach of, or default under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Purchaser pursuant to, any contract, indenture, mortgage, loan agreement, deed, trust, note, lease, sublease,
voting agreement, voting trust or other instrument or agreement to which the Purchaser is a party or by which it may be bound, or to which any of the property or assets of the Purchaser is subject, nor will such action result in any violation of the
provisions of the charter or bylaws, or other organizational documents, of the Purchaser or any applicable statute, law, rule, regulation, ordinance, decision, directive or order applicable to the Purchaser or its property or assets. 
 5. Survival of Representations, Warranties and Agreements. Notwithstanding any investigation made by any party to this Agreement, all
representations and warranties made by the Company and the Purchasers in this Agreement shall survive for one (1) year from the execution of this Agreement.

 - 10 - 








 
controlling person become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or
otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, which consent shall not be unreasonably withheld), insofar as such actual and direct losses, claims, direct damages,
liabilities or reasonable expenses (or actions in respect thereof as contemplated below) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, including
the Prospectus, financial statements and schedules, and all other documents filed as a part thereof, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of

Registration Statement at the time of effectiveness if no Rule 424(b) filing is required (the “Prospectus”), or any amendment or supplement thereto, or (ii) arise out of or are based upon the omission or alleged omission to state in
any of them a material fact required to be stated therein or necessary to make the statements in any of them, in light of the circumstances under which they were made, not misleading, or (iii) arise out of or are based in whole or in part on
any inaccuracy in the representations and warranties of the Company contained in this Agreement, or any failure of the Company to perform its obligations under this Agreement or under law (the events in clauses (i), (ii), or (iii), collectively are
referred to herein as the “Company Indemnification Events”), and shall reimburse each Purchaser and each such controlling person as the case may be, for the indemnifiable amounts provided for herein on demand as such expenses are incurred;
provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon any Purchaser Indemnification Event (as defined below). 
 6.3.2 Indemnification by the Purchaser. The Purchaser will indemnify and hold harmless the Company, each of its directors, each of its officers
who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, against any actual and direct losses, claims, direct damages, liabilities or reasonable expenses to which the Company,
each of its directors, each of its officers who signed the Registration Statement or controlling person become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or
otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Purchaser, which consent shall not be unreasonably withheld) insofar as such actual and direct losses, claims, direct damages,
liabilities or reasonable expenses (or actions in respect thereof as contemplated below) arise out of or are based upon (i) the failure of such Purchaser to comply with the covenants and agreements contained in Sections 4.2 or 6.2 of this
Agreement respecting the sale of the Securities or (ii) the inaccuracy of any representation made by such Purchaser in this Agreement or the Questionnaires or (iii) any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement, the Prospectus, or any amendment or supplement to the Registration Statement or Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a fact required to be stated
therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement,
the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to

the Company by or on behalf of such Purchaser expressly for use therein (the events in clauses (i), (ii), or (iii), collectively are referred to herein as
the “Purchaser Indemnification Events”), and shall reimburse the Company or such officer, director or controlling person, as the case may be, for the indemnifiable amounts provided for herein on demand as such expenses are incurred;
provided, however, that the Purchaser shall not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon any Company Indemnification Event. Notwithstanding the foregoing, the
Purchaser’s aggregate obligation to indemnify the Company and such officers, directors and controlling persons shall be limited to the net amount received by the Purchaser from the sale of the Securities. 
 6.3.3 Indemnification Procedure. 
 (a) Promptly after receipt by an indemnified party under this Section 6.3 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party
under this Section 6.3, promptly notify the indemnifying party in writing of the claim; but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or
otherwise under the indemnity agreement contained in this Section 6.3 or to the extent it is not prejudiced as a result of such failure. 
 (b) In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent
that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and
the indemnified party shall have reasonably concluded that there may be a conflict between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available
to it or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to so assume the defense of such action, the indemnifying party
will not be liable to such indemnified party under this Section 6.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless: 
 (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the
preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, approved by such indemnifying party representing all of the indemnified parties who are parties to
such action) or 
 (ii) the indemnifying party shall not have employed Heller Ehrman LLP or other counsel reasonably satisfactory to the
indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the

indemnifying party. Notwithstanding the provisions of this Section 6.3, the Purchaser shall not be liable for any indemnification obligation under this
Agreement in excess of the amount of net proceeds received by the Purchaser from the sale of the Securities, unless such obligation has resulted from the gross negligence or willful misconduct of the Purchaser. 
 6.3.4 Contribution. If a claim for indemnification under this Section 6.3 is unavailable to an indemnified party (by reason of public policy
or otherwise), then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to in
this Agreement, in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified party in connection with the actions, statements or omissions that resulted in such losses, claims, damages, liabilities or
expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or
alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied by, such indemnifying party or indemnified party, and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of any losses, claims, damages, liabilities or expenses shall be deemed to include, subject
to the limitations set forth in this Section 6.3, any reasonable attorneys’ or other reasonable fees or expenses incurred by such party in connection with any proceeding to the extent such party would have been indemnified for such fees or
expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. 
 The parties hereto
agree that it would not be just and equitable if contribution pursuant to this Section 6.3 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in
the immediately preceding paragraph. Notwithstanding the provisions of this Section 6.3, no Purchaser shall be required to contribute, in the aggregate, any amount in excess of the amount by which the proceeds actually received by such
Purchaser from the sale of Securities exceeds the amount of any damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No party to this Agreement guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any other party to this Agreement who was not guilty of such fraudulent misrepresentation. 
 6.4 Termination of Conditions and Obligations. The restrictions imposed by Section 4 or this Section 6 upon the transferability of the
Securities shall cease and terminate as to any particular number of the Securities upon the passage of two years from the Closing Date or at such time as an opinion of counsel satisfactory in form and substance to the Company shall have been
rendered to the effect that such conditions are not necessary in order to comply with the Securities Act. 
 6.5 Rule 144 Information.
For two years after the date of this Agreement, the Company shall use its best efforts to file all reports required to be filed by it under the Securities Act, the Rules and Regulations and the Exchange Act and shall take such further action to the
extent required to enable the Purchasers to sell the Securities pursuant to Rule 144 under the Securities Act (as such rule may be amended from time to time).

to, promptly process requests for transfer or de-legending of Securities or certificates representing Conversion Shares in compliance with this Agreement.

of the State of California, without reference to conflict of laws, and the federal law of the United States of America.

Filing and contemporaneously therewith and (ii) as required by applicable law. 
 14. Stock Splits, Dividends and other Similar
Events. The provisions of this Agreement shall be appropriately adjusted to reflect any stock split, stock dividend, reorganization or other similar event that may occur with respect to the Company after the date hereof.
