as shall be specified by Investor. In the event of a proposed transfer, the transferring Investor shall give written notice to the Company of Investor’s intention to effect such transfer. Each such notice shall describe the manner and
circumstances of the proposed transfer in sufficient detail, and shall, if the Company so requests, be accompanied by either: (i) a written opinion of legal counsel, who shall be reasonably satisfactory to the Company, addressed to the Company
and reasonably satisfactory in form and substance to the Company’s counsel, to the effect that the proposed transfer of the Note may be effected without registration under the Securities Act or (ii) a “no action” letter from the
SEC to the effect that the transfer of such Note without registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto, whereupon the holder of such restricted securities shall be entitled to
transfer such restricted securities in accordance with the terms of the notice delivered by such holder to the Company; provided, however, that no opinion or “no action” letter need be obtained with respect to a transfer to:
(a) an affiliate (as such term is defined in the Securities Act) of Investor; (b) a partner, active or retired, of Investor; (c) the estate of any such partner; or (d) the spouse, children, grandchildren or spouse of such
children or grandchildren of any holder or to trusts for the benefit of Investor or such Persons. In connection with any transfer in accordance with this Section 6.2 and at all other times hereunder, Investor shall be entitled to surrender its
Note to the Company together with a written request for the issuance of one or more new Note, specifying the denomination or denominations thereof and, in the case of a transfer of a Note, the name and address of the new transferee or transferees.
As soon as reasonably practicable, the Company shall issue a new Note bearing the same interest rate and in the same form, in the same aggregate principal amount as the Note being surrendered in the name of Investor. Each such new Note shall be
dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. Each Note presented or surrendered for reissuance and
registration of a new Note shall be endorsed, or, in the case of a transfer of a Note, shall be accompanied by a duly executed written instrument of transfer in an appropriate form. The applicable Investor shall be responsible for any transfer taxes
associated with the 

  

 13 








 
transfer of any Note. Any transferee, by its acceptance of a Note in its name (or the name of its nominee), shall be deemed to have made the representations
set forth in Section 4. Notwithstanding the foregoing, any such transferee shall execute and deliver a counterpart of this Agreement, the Security Agreement and the Guaranty to the Company and Investor, in form and substance satisfactory to
Investor, and, by delivering such counterpart, such transferee shall be deemed to agree to be bound by the provisions of this Agreement, the Security Agreement, the Guaranty and the other Related Documents. 
 6.3 Issuance of Notes. The Company and Investor may treat the Person in whose name any Note is issued as the absolute owner of such Note for all
purposes, and all payments in respect of a Note made to any such Person or upon such Person’s order shall satisfy and discharge the liability of the Company or Investor (as the case may be) on such Note to the extent of the sum or sums so paid.

 6.4 Mutilated, Destroyed, Lost or Stolen Note. In case the Note shall become mutilated or defaced, or be destroyed, lost or stolen,
the Company shall execute and deliver a new Note of like principal amount in exchange and substitution for the mutilated or defaced Note, or in lieu of and in substitution for the destroyed, lost or stolen Note. In the case of a mutilated or defaced
Note, Investor shall surrender such Note to the Company. In the case of any destroyed, lost or stolen Note, Investor shall furnish to the Company: (i) evidence to the Company’s satisfaction of the destruction, loss or theft of such Note
and (ii) such security or indemnity as may be reasonably required by the Company.

(ii) any material dispute or default by the Company, any of its Subsidiaries or any other party under any joint venture, partnering, distribution, cross-licensing, strategic alliance, collaborative research or manufacturing, license or similar
agreement which would reasonably be expected to have a Material Adverse Effect, or (iii) any default or Event of Default hereunder or under any Related Document. 
 7.2 Existence. The Company shall maintain and preserve the existence, present form of business and all rights and privileges necessary or desirable in the normal course of business of the Company and its

Company shall furnish to Investor such endorsements, and upon Investor’s request, copies of any or all such policies. If no Event of Default has occurred and is continuing, proceeds payable under any casualty policy will, at the Company’s
option, be payable to the Company to replace the property subject to the claim, provided that such replacement property shall be deemed part of the Collateral (as defined in the Security Agreement). If an Event of Default has occurred and is
continuing, then, at Investor’s option, the proceeds payable under any casualty policy will be payable to Investor and applied toward satisfaction of the Obligations.

account control agreements, securities account control agreement and other documents, the filing or recording of any of the foregoing, and the delivery of stock certificates and other collateral with respect to which perfection is obtained by
possession) to ensure that the obligations of the Company and its Subsidiaries hereunder and under the other Related Documents are secured by substantially all of the assets, equity securities and personal property of the Company and its
Subsidiaries (whether now existing or promptly upon the acquisition or creation thereof after the date hereof). 
 7.12 Additional

substantial or material part of the assets of the Company or any Subsidiary (other than any sale, transfer or other disposition of all or a substantial or material part of any products or assets of the Company pursuant to the terms of the letter

 (l) the Company or any Subsidiary shall fail to perform or observe any covenant or agreement contained in this Agreement or any

Company’s receipt of notice of such breach from Investor or the date on which such breach first becomes known to any officer of the Company; provided, however, that if such breach is not capable of being cured within such thirty
(30)-day period and the Company timely notifies Investor of such fact and the Company diligently pursues such cure, then the cure period shall be extended to the date requested in the Company’s notice but in no event more than ninety
(90) days from the initial breach; provided, further, that such additional sixty (60)-day opportunity to cure shall not apply in the case of any failure to perform or observe any covenant which has been the subject of a prior
failure within the preceding one hundred eighty (180) days or which is a willful and knowing breach by the Company or any Subsidiary;

or equity financing. No delay or omission to exercise any right, power or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, will impair any such right, power or remedy of such
non-breaching or non-defaulting party nor will it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring; nor will any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on
the part of any party of any provisions or conditions of this Agreement, must be in writing and will be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to
any party, will be cumulative and not alternative.

continuance of an Event of Default described in Section 9.1(c), each of (i) the unpaid principal amount of and accrued interest on the Note and (ii) all other Obligations shall automatically become immediately due and payable, without
presentment, demand, protest or other requirements of any kind, all of 

  

 22 








 
which are hereby expressly waived by the Company, and (b) upon the occurrence and during the continuance of any other Event of Default, Investor shall
be entitled to, at its option, exercise any or all of the rights and remedies available to a secured party under the UCC or any other applicable law, and exercise any or all of their rights and remedies provided for in this Agreement and in any
Related Document. The obligations of the Company under this Agreement shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any Obligations is rescinded or must otherwise be returned by a Investor upon,
on account of or in connection with, the insolvency, bankruptcy or reorganization of the Company, any Subsidiary or otherwise, all as though such payment had not been made. 
 9.3 Sale of Collateral. In addition to any other rights set forth in this Agreement or any of the Related Documents, upon the occurrence
and during the continuance of an Event of Default, Investor may sell all or any part of the Collateral, at public or private sales, to themselves, a wholesaler, retailer or investor, for cash, upon credit or for future delivery, and at such price or
prices as Investor may deem commercially reasonable. To the extent permitted by law, the Company hereby specifically waives all rights of redemption and any rights of stay or appraisal that it has or may have under any applicable law in effect from
time to time. Any such public or private sales shall be held at such times and at such place(s) as Investor may determine. In case of the sale of all or any part of the Collateral on credit or for future delivery, the Collateral so sold may be
retained by Investor until the selling price is paid by the purchaser, but Investor shall not incur any liability in case of the failure of such purchaser to pay for the Collateral and, in case of any such failure, such Collateral may be resold.
Investor may, instead of exercising their power of sale, proceed to enforce their security interest in the Collateral by seeking a judgment or decree of a court of competent jurisdiction. Without limiting the generality of the foregoing, if an Event
of Default is in effect: 
 (a) Subject to the rights of any third parties, Investor may, in compliance with applicable
law, license, or sublicense, whether general, special or otherwise, and whether on an exclusive or non-exclusive basis, any Copyrights, Patents, Trademarks or other Intellectual Property included in the Collateral throughout the world for such term
or terms, on such conditions and in such manner as Investor shall in their sole discretion determine; 
 (b) Investor
may (without assuming any obligations or liability thereunder), at any time and from time to time, enforce (and shall have the exclusive right to enforce) against any licensee or sublicensee all rights and remedies of the Company in, to and under
any Copyright Licenses, Patent Licenses, Trademark Licenses or other Intellectual Property and take or refrain from taking any action under any thereof, and the Company hereby releases Investor from, and agrees to hold Investor free and harmless
from and against any claims arising out of, any lawful action so taken or omitted to be taken with respect thereto other than claims arising out of an Investor’s gross negligence or willful misconduct; and 
 (c) Upon request by Investor, the Company will execute and deliver to Investor a power of attorney, in form and substance
reasonably satisfactory to Investor, for the implementation of any lease, assignment, license, sublicense, grant of option, sale or other disposition of a Copyright, Patent, Trademark or other Intellectual Property. In the event of any such
disposition pursuant to this clause (c), the Company shall supply its know-how and expertise 

  

 23 








 
relating to the products or services made or rendered in connection with Patents, the manufacture and sale of the products bearing Trademarks and its
customer lists and other records relating to such Copyrights, Patents, Trademarks or other Intellectual Property and to the distribution of said products, to Investor. 
 9.4 Company’s Obligations Upon Default. Upon the request of Investor after the occurrence and during the continuance of an Event of Default, the Company will: 
 (a) Assemble and make available to Investor the Collateral at such place(s) as Investor shall reasonably designate, segregating all
Collateral so that each item is capable of identification; and 
 (b) Subject to the rights of any lessor, permit
Investor, by Investor’s officers, employees, agents and representatives, to enter any premises where any Collateral is located, to take possession of the Collateral, to complete the processing, manufacture or repair of any Collateral, and to
remove the Collateral, or to conduct any public or private sale of the Collateral, all without any liability of Investor for rent or other compensation for the use of the Company’s premises.

obligations, losses, claims, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever, including the reasonable fees and disbursements of counsel to an Indemnified Person (including allocated
costs of internal counsel), that may be imposed on, incurred by or asserted against any Indemnified Person (i) in any way relating to or arising out of this Agreement or any of the Related Documents, the use or intended use of the proceeds of

this Agreement or any of the Related Documents and (iii) with respect to any investigation, litigation or other proceeding relating to any of the foregoing, irrespective of whether the Indemnified Person shall be designated a party thereto (the
“Indemnified Liabilities”); provided, however, that the Company shall not be liable to any Indemnified Person for any portion of such Indemnified Liabilities to the extent that they are found by a final decision of a
court of competent jurisdiction to have resulted from such Indemnified Person’s gross negligence or willful misconduct. If and to the extent that the foregoing indemnification is for any reason held unenforceable, the Company agrees to make the
maximum contribution to the payment and satisfaction of each of the Indemnified Liabilities that is permissible under applicable law.

 9. No course of dealing between the Company and the Holder or any delay on the part of the Holder in exercising any rights or remedies shall operate as a
waiver of any such right or remedy of the Holder. 
 10. This Note shall be binding on and inure to the benefit of and be enforceable by the
Company, the Holder and their respective successors and assigns. The Company may not assign, transfer, hypothecate or otherwise convey its rights, benefits, obligations or duties hereunder without the prior express written consent of the Majority
Investors. Any such purported assignment, transfer, hypothecation or other conveyance by the Company without the prior express written consent of the Majority Investors shall be void. 
 11. Whenever possible, each provision of this Note shall be interpreted in such manner as to be effective and valid under all applicable laws and
regulations. If, however, any provision of this Note shall be prohibited by or invalid under any such law or regulation in any jurisdiction, it shall, as to such jurisdiction, be deemed modified to conform to the minimum requirements of such law or
regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions of this Note, or the validity or effectiveness of
such provision in any other jurisdiction.

expressly indicated, include the Collateral Agent in its individual capacity. The Collateral Agent shall receive no compensation but shall be entitled to reimbursement of expenses and indemnification as set forth herein. The Collateral Agent’s

Secured Parties and at the direction of the Majority Secured Parties to: (i) exercise or refrain from exercising any rights, remedies or powers of the Secured Parties under applicable law in respect of the Notes or all or any portion of any
Collateral; (ii) sell, release, surrender, realize upon or otherwise deal with, in any manner and in any order, all or any portion of any Collateral; (iii) make any demands or give any notices under or in connection with this Agreement,

Parties, including legal counsel for the Collateral Agent or the Secured Parties. As to the exercise of any of its powers and discharge of any of its duties, the Collateral Agent shall be entitled to obtain instructions of the Majority Secured
Parties, and shall be fully protected in acting or refraining from acting upon such instructions and such instructions shall be binding upon all Secured Parties. Except for actions expressly required of the Collateral Agent hereunder, the Collateral
Agent shall in all cases be fully justified in failing or refusing to act under this Agreement, the Purchase Agreement and the Related Documents unless it shall be indemnified to its satisfaction by the Secured Parties against any and all liability
and expense that may be incurred by reason of taking or continuing to take any such action, and the Collateral Agent shall not in any event be required to take any action that exposes the Collateral Agent to liability or that is contrary to this
Agreement, the Purchase Agreement, the Related Documents or applicable law.

 (c) The Collateral Agent shall hold the Collateral for the ratable benefit of Secured
Parties in accordance with their Pro Rata Shares. Distribution of Collateral or any and all proceeds of any of the Collateral shall be made in accordance with Secured Parties respective Pro Rata Shares. 
 (d) Neither the Collateral Agent nor any of its directors, officers, employees or agents shall be responsible to any Secured Party for any
action taken or omitted to be taken by it or them hereunder or in connection herewith, except in the case of gross negligence or willful misconduct. The Collateral Agent may rely upon any notice, consent, certificate, telegram, facsimile, telex or
teletype message, statement or other instrument or writing believed by it to be genuine and signed or sent by the proper party or parties or by acting upon any representation or warranty made or deemed to be made hereunder or under any other Related
Document. The Collateral Agent shall use the level of care it uses with respect to its own property of a similar nature to assure the safe custody of the Collateral in its possession. Beyond the exercise of such level of care to assure the safe
custody of the Collateral in its possession as the Collateral Agent, and the accounting for any monies actually received by the Collateral Agent in such capacity, the Collateral Agent shall have no duty or liability to exercise or preserve any
rights, privileges and powers pertaining to the Collateral. 
 (e) The Secured Parties hereby agree to indemnify the
Collateral Agent, and any affiliates, directors, officers, employees, partners, members, agents, counsel and other advisors (collectively, the “Related Persons”) of the Collateral Agent ratably in accordance with their Pro Rata
Share, against and hold each of them harmless from any and all liabilities, obligations, losses, claims, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever, including the fees and
disbursements of counsel to the Collateral Agent (collectively, the “Liabilities”), that may be imposed on, incurred by or asserted against the Collateral Agent or any such Related Person to be indemnified, in any way relating to or
arising out of this Agreement, the Purchase Agreement or the Related Documents or any action taken or omitted by the Collateral Agent or other such Related Person to be indemnified in connection with any of the foregoing, unless such Liabilities

therein in order to effect the intent of this Agreement, all as fully and effectively as such Grantor might do. 
 The foregoing power of
attorney is coupled with an interest and irrevocable so long as the Obligations have not been paid in full in cash and performed in full. Each Grantor hereby ratifies, to the extent permitted by law, all that the Collateral Agent shall lawfully and

provided, however, that the Grantors shall be credited with the net proceeds of sale only when such proceeds are finally collected by the Collateral Agent. The Collateral Agent shall have the right upon any such public sale, and, to
the extent permitted by law, upon any such private sale, to purchase the whole or any part of the Collateral so sold, free of any right or equity of redemption, which right or equity of redemption the Grantors hereby release, to the extent permitted

 16 








 
ordinary mail, postage prepaid, to the address of the Grantors set forth herein, of the place and time of any public sale or of the time after which any
private sale or other intended disposition is to be made, shall be deemed reasonable notice thereof if such notice is sent ten (10) Business Days prior to the date of such sale or other disposition or the date on or after which such sale or
other disposition may occur, provided that the Collateral Agent may provide the Grantors shorter notice or no notice, to the extent permitted by the UCC or other applicable law.

license or sublicense any of the Collateral. 
 (c) The cash proceeds actually received from the sale or other disposition or
collection of the Collateral and any other amounts received in respect of the Collateral or the application of which is not otherwise provided for herein, shall be applied first, to the payment of the reasonable costs and expenses of the
Collateral Agent (including the reasonable costs and expenses of legal counsel) in exercising or enforcing its rights hereunder and in collecting or attempting to collect any of the Collateral; and second, to the payment of the Obligations.
Any surplus thereof that exists after payment and performance in full of the Obligations shall be promptly paid over to the Grantors or otherwise disposed of in accordance with the UCC or other applicable law. The Grantors shall remain liable to the
Collateral Agent and the Secured Parties for any deficiency that exists after any sale or other disposition or collection of the Collateral. 
 (d) (i) Unless an Event of Default shall have occurred and be continuing and the Collateral Agent shall have given notice to the relevant Grantor of the Collateral Agent’s intent to exercise its corresponding
rights pursuant to Section 9(d)(ii), each Grantor shall be permitted to receive all cash dividends paid in respect of the Pledged Stock paid in the normal course of business of the relevant Issuer and consistent with past practice, to the
extent permitted in the Purchase Agreement, and to exercise all voting and corporate rights with respect to the Pledged Collateral; provided, however, that no vote shall be cast or corporate right exercised or other action taken which,
in the Collateral Agent’s reasonable judgment, would impair the Collateral or which would be inconsistent with or result in any violation of any provision of the Purchase Agreement, this Agreement or any Related Document. 
 (ii) If an Event of Default shall occur and be continuing and the Collateral Agent shall give notice of its intent to exercise such rights
to the relevant Grantor or Grantors, (i) the Collateral Agent shall have the right to receive any and all cash dividends, payments or other Proceeds paid in respect of the Pledged Collateral and make application thereof to the Obligations in
the order set forth in Section 9(c) and (ii) any or all of the Pledged Collateral shall be registered in the name of the Collateral Agent or its nominee, and the Collateral Agent or its nominee may thereafter exercise (x) all voting,
corporate and other rights pertaining to such Pledged Collateral at any meeting of stockholders of the relevant Issuer or Issuers or otherwise and (y) any and all rights of conversion, exchange and subscription and any other rights, privileges
or options pertaining to such Pledged Collateral as if it were the absolute owner thereof (including, without limitation, the right to exchange at its discretion any and all of 

  

 17 








 
the Pledged Collateral upon the merger, consolidation, reorganization, recapitalization or other fundamental change in the corporate structure of any Issuer,
or upon the exercise by any Grantor or the Collateral Agent of any right, privilege or option pertaining to such Pledged Collateral, and in connection therewith, the right to deposit and deliver any and all of the Pledged Collateral with any
committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Agent may determine), all without liability except to account for property actually received by it, but the Collateral Agent shall have
no duty to any Grantor to exercise any such right, privilege or option and shall not be responsible for any failure to do so or delay in so doing.

Issuer shall be fully protected in so complying and (ii) unless otherwise expressly permitted hereby, pay any dividends or other payments with respect to the Pledged Collateral directly to the Collateral Agent. 
 (e) (i) If the Collateral Agent shall determine to exercise its right to sell any or all of the Pledged Stock pursuant to
Section 9(a), and if in the opinion of the Collateral Agent it is necessary or advisable to have the Pledged Stock, or that portion thereof to be sold, registered under the provisions of the Securities Act of 1933, as amended, the relevant
Grantor will cause the Issuer thereof to (i) execute and deliver, and cause the directors and officers of such Issuer to execute and deliver, all such instruments and documents, and do or cause to be done all such other acts as may be, in the
opinion of the Collateral Agent, necessary or advisable to register the Pledged Stock, or that portion thereof to be sold, under the provisions of the Securities Act of 1933, as amended, (ii) use its best efforts to cause the registration
statement relating thereto to become effective and to remain effective for a period of one year from the date of the first public offering of the Pledged Stock, or that portion thereof to be sold, and (iii) make all amendments thereto and/or to
the related prospectus which, in the opinion of the Collateral Agent, are necessary or advisable, all in conformity with the requirements of the Securities Act of 1933, as amended, and the rules and regulations of the Securities and Exchange
Commission applicable thereto. Each Grantor agrees to cause such Issuer to comply with the provisions of the securities or “Blue Sky” laws of any and all jurisdictions that the Collateral Agent shall designate and to make available to its
security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act of 1933, as amended. 
 (ii) Each Grantor recognizes that the Collateral Agent may be unable to effect a public sale of any or all the Pledged Stock, by reason of
certain prohibitions contained in the Securities Act of 1933, as amended, and applicable state securities laws or otherwise, and may be compelled to resort to one or more private sales thereof to a restricted group of purchasers that will be obliged
to agree, among other things, to acquire such securities for their own account for investment and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that any such private sale may result in prices and other
terms less favorable than if such sale were a public sale and, notwithstanding such 

  

 18 








 
circumstances, agrees that any such private sale shall be deemed to have been made in a commercially reasonable manner. The Collateral Agent shall be under
no obligation to delay a sale of any of the Pledged Stock for the period of time necessary to permit the Issuer thereof to register such securities for public sale under the Securities Act of 1933, as amended, or under applicable state securities
Laws, even if such Issuer would agree to do so. 
 (iii) Each Grantor agrees to use its best efforts to do or cause to be done
all such other acts as may be necessary to make such sale or sales of all or any portion of the Pledged Stock pursuant to this Section 9(e) valid and binding and in compliance with any and all other applicable laws. Each Grantor further agrees
that a breach of any of the covenants contained in this Section 9(e) will cause irreparable injury to the Collateral Agent and the Secured Parties, that the Collateral Agent and the Secured Parties have no adequate remedy at law in respect of
such breach and, as a consequence, that each and every covenant contained in this Section 9(e) shall be specifically enforceable against such Grantor, and such Grantor hereby waives and agrees not to assert any defenses against an action for
specific performance of such covenants except for a defense that no Event of Default has occurred under the Purchase Agreement. 
 (f) The Collateral Agent hereby authorizes each Grantor to collect such Grantor’s Receivables, subject to the Collateral Agent’s direction and control after the occurrence and during the continuance of an Event of Default, and the
Collateral Agent may curtail or terminate said authority at any time after the occurrence and during the continuance of an Event of Default. If required by the Collateral Agent at any time after the occurrence and during the continuance of an Event
of Default, any payments of Receivables, when collected by any Grantor, (i) shall be forthwith (and, in any event, within two Business Days) deposited by such Grantor in the exact form received, duly indorsed by such Grantor to the Collateral
Agent if required, in a collateral account maintained under the sole dominion and control of the Collateral Agent, subject to withdrawal by the Collateral Agent for the account of the Secured Parties at its discretion, and (ii) until so turned
over, shall be held by such Grantor in trust for the Collateral Agent and the Secured Parties, segregated from other funds of such Grantor. Each such deposit of Proceeds of Receivables shall be accompanied by a report identifying in reasonable
detail the nature and source of the payments included in the deposit. 
 (g) At any time after the occurrence and during the
continuance of an Event of Default, at the Collateral Agent’s request, each Grantor shall deliver to the Collateral Agent all original and other documents evidencing, and relating to, the agreements and transactions that gave rise to the
Receivables, including, without limitation, all original orders, invoices and shipping receipts. 
 (h) At any time after the
occurrence and during the continuance of an Event of Default, each Grantor will cooperate with the Collateral Agent to establish a system of lockbox accounts, under the sole dominion and control of the Collateral Agent, into which all Receivables
shall be paid and from which all collected funds will be transferred to a Collateral Account. 
  

 19 








 (i) Upon the request of the Collateral Agent at any time after the occurrence and during
the continuance of an Event of Default, each Grantor hereby authorizes the Collateral Agent to notify each obligor on the Receivables that the Receivables have been assigned to the Collateral Agent for the ratable benefit of the Secured Parties as
Collateral hereunder and to instruct such obligor to make all payments in respect thereof directly to the Collateral Agent or to the Collateral Account or as otherwise directed by the Collateral Agent. 
 Section 10. Certain Waivers. Each Grantor waives, to the fullest extent permitted by law, (i) any right of redemption with respect to
the Collateral, whether before or after sale hereunder; and (ii) any right to require the Collateral Agent or any Secured Party (A) to proceed against any Person, (B) to exhaust any other collateral or security for any of the
Obligations, (C) to pursue any remedy in any Secured Party’s or Collateral Agent’s power, or (D) to make or give any presentments, demands for performance, notices of nonperformance, protests, notices of protests or notices of
dishonor in connection with any of the Collateral. 
 Section 11. Notices. All notices or other communications hereunder shall
be in writing (including by facsimile transmission) and mailed, sent or delivered to the respective parties hereto at or to their respective addresses or facsimile numbers set forth below their names on the signature pages hereof, or at or to such
other address or facsimile number as shall be designated by any party in a written notice to the other parties hereto. All such notices and other communications shall be effective (i) if delivered by hand, when delivered; (ii) if sent by
mail, upon the earlier of the date of receipt or five Business Days after deposit in the mail, first class (or air mail, with respect to communications to be sent to or from the United States); (iii) if sent by overnight mail, one day after
deposit with the overnight courier; and (iv) if sent by facsimile transmission, when sent so long as a valid confirmation is received by sender. 
 Section 12. No Waiver; Cumulative Remedies. No failure on the part of any Secured Party or the Collateral Agent to exercise, and no delay in exercising, any right, remedy, power or privilege under this
Agreement, the Purchase Agreement and the Related Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, remedy, power or privilege preclude any other or further exercise thereof or the exercise of
any other right, remedy, power or privilege. The rights and remedies under this Agreement, the Purchase Agreement and the Related Documents are cumulative and not exclusive of any rights, remedies, powers and privileges that may otherwise be
available to such Secured Party or the Collateral Agent. 
 Section 13. Binding Effect. This Agreement shall be binding upon,
inure to the benefit of and be enforceable by any Grantor, any Secured Party, any Collateral Agent appointed hereunder and their respective successors and assigns. 
 Section 14. Governing Law and Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the law of the State of California, without regard to the choice of law rules thereof,
except to the extent the validity or perfection of the security interests hereunder, or the remedies hereunder, in respect of any Collateral are governed by the law of a jurisdiction other than California. 
 Section 15. Entire Agreement; Amendment and Waiver. This Agreement contains the entire agreement of the parties with respect to the subject
matter hereof and no amendment to this Agreement, or any waiver of any provision hereof, shall be effective unless it is in writing and signed by the Majority Secured Parties and (in the case of any amendment) each Grantor; except that no amendment,
waiver or consent shall, unless in writing and additionally signed by the Collateral Agent affect the rights or duties of the Collateral Agent under this Agreement. 
  

 20 








 Section 16. Severability. Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under all applicable laws and regulations. If, however, any provision of this Agreement shall be prohibited by or invalid under any such law or regulation in any jurisdiction, it shall, as to
such jurisdiction, be deemed modified to conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it shall be ineffective and invalid only to the extent of such prohibition or invalidity
without affecting the remaining provisions of this Agreement, or the validity or effectiveness of such provision in any other jurisdiction. 
 Section 17. Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which
taken together shall constitute but one and the same agreement. 
 Section 18. Termination. This Agreement shall be terminated
upon indefeasible payment and performance in full of all Obligations. Upon termination, the Secured Parties and the Collateral Agent, as applicable, shall promptly, at the cost of the Grantors, execute and deliver to the Grantors such documents and
instruments reasonably requested by the Grantors as shall be necessary to evidence termination of all security interests given by the Grantors to the Secured Parties hereunder; provided, however, that the obligations under Section 4 hereof
shall survive such termination. 
 Section 19. Suretyship Waivers by Grantors, etc. 
 (a) Each Grantor agrees that its Obligations are irrevocable, absolute, independent and unconditional and shall not be affected by any
circumstance that constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Grantor agrees as follows:
(i) Secured Parties may from time to time, without notice or demand and without affecting the validity or enforceability of the Purchase Agreement or any Related Document or giving rise to any limitation, impairment or discharge of such
Grantor’s liability under the Purchase Agreement or any Related Document, (A) renew, extend, accelerate or otherwise change the time, place, manner or terms of payment of the Obligations, (B) settle, compromise, release or discharge,
or accept or refuse any offer of performance with respect to, or substitutions for, the Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations, (C) request and accept
guaranties of the Obligations and take and hold other security for the payment of the Obligations, (D) release, exchange, compromise, subordinate or modify, with or without consideration, any other security for payment of the Obligations, any
guaranties of the Obligations, or any other obligation of any Person with respect to the Obligations, (E) enforce and apply any other security now or hereafter held by or for the benefit of Secured Party in respect of the Obligations and direct
the order or manner of sale thereof, or exercise any other right or remedy that a Secured 

  

 21 








 
Party may have against any such security, as Secured Party in its discretion may determine consistent with the Purchase Agreement, the Related Documents and
any applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable, and (F) exercise any other rights
available to such Secured Party under the Purchase Agreement and the Related Documents at law or in equity; and (ii) the Purchase Agreement, the Related Documents and the Obligations shall be valid and enforceable and shall not be subject to
any limitation, impairment or discharge for any reason (other than payment in full in cash of the Obligations), including, without limitation, the occurrence of any of the following, whether or not such Grantor shall have had notice or knowledge of
any of them: (A) any failure to assert or enforce or agreement not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power
or remedy with respect to the Obligations or any agreement relating thereto, or with respect to any guaranty of or other security for the payment of the Obligations, (B) any waiver, amendment or modification of, or any consent to departure
from, any of the terms or provisions (including, without limitation, provisions relating to events of default) of the Purchase Agreement, any of the Related Documents or any agreement or instrument executed pursuant thereto, or of any guaranty or
other security for the Obligations, (C) the Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect, (D) the application of payments received from any source to the
payment of indebtedness other than the Obligations, even though a Secured Party might have elected to apply such payment to any part or all of the Obligations, (E) any failure to perfect or continue perfection of a security interest in any
other collateral that secures any of the Obligations, (F) any defenses, set-offs or counterclaims that any Grantor may allege or assert against a Secured Party in respect of the Obligations, including, but not limited to, failure of
consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury, and (G) any other act or thing or omission, or delay to do any other act or thing, that may or might in any manner or to
any extent vary the risk of any Grantor as an obligor in respect of the Obligations. 
 (b) Each Grantor hereby waives, for
the benefit of the Secured Parties: (i) any right to require a Secured Party as a condition of payment or performance by such Grantor, to (A) proceed against such Grantor, any guarantor of the Obligations or any other Person,
(B) proceed against or exhaust any other security held from such Grantor, any guarantor of the Obligations or any other Person, (C) proceed against or have resort to any balance of any deposit account or credit on the books of Secured
Party of such Grantor or any other Person, or (D) pursue any other remedy in the power of Secured Party whatsoever; (ii) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of such Grantor
including, without limitation, any defense based on or arising out of the lack of validity or the unenforceability of the Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of such Grantor from
any cause other than payment in full of the Obligations; (iii) any defense based upon any statute or rule of law that provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of
the principal; (iv) any defense based upon a Secured Party’s errors or omissions in the administration of the Obligations, except behavior that amounts to bad faith; (v) (A) any principles or provisions of law, statutory or
otherwise, that are or might be in conflict with the 

  

 22 








 
terms of the Purchase Agreement, any Related Document and any legal or equitable discharge of such Grantor’s obligations under the Purchase Agreement or
any Related Document, (B) the benefit of any statute of limitations affecting such Grantor’s liability hereunder or the enforcement of any Obligations, (C) any rights to set-offs, recoupments and counterclaims, and
(D) promptness, diligence and any requirement that a Secured Party protect, secure, perfect or insure any other security interest or lien or any property subject thereto; (vi) notices, demands, presentments, protests, notices of protest,
notices of dishonor and notices of any action or inaction, notices of default under the Purchase Agreement, any Related Document or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Obligations or
any agreement related thereto, notices of any extension of credit to such Grantor and notices of any of the matters referred to in the preceding paragraph and any right to consent to any thereof; and (vii) to the fullest extent permitted by
law, any defenses or benefits that may be derived from or afforded by law that limit the liability of or exonerate guarantors or sureties, or that may conflict with the terms of the Purchase Agreement or any Related Document. 
 (c) As used in this Section 19(c), any reference to “the principal” includes each Grantor, and any reference to “the
creditor” includes each Secured Party. In accordance with Section 2856 of the California Civil Code (a) each Grantor waives any and all rights and defenses available to the Grantor by reason of Sections 2787 to 2855, inclusive, 2899
and 3433 of the California Civil Code. No other provision of this Agreement shall be construed as limiting the generality of any of the covenants and waivers set forth in this Section 19. 
 (d) Until the Obligations shall have been paid in full in cash, each Grantor shall withhold exercise of (i) any claim, right or
remedy, direct or indirect, that such Grantor now has or may hereafter have against the other Grantors or any of their assets in connection with the Purchase Agreement and the Related Documents or the performance by such Grantor of its obligations
under the Purchase Agreement and the Related Documents, in each case whether such claim, right or remedy arises in equity, under contract, by statute (including, without limitation, under California Civil Code Section 2847, 2848 or 2849), under
common law or otherwise and including without limitation (A) any right of subrogation, reimbursement or indemnification that a Grantor now has or may hereafter have against another Grantor, (B) any right to enforce, or to participate in,
any claim, right or remedy that a Secured Party now has or may hereafter have against any Grantor, and (C) any benefit of, and any right to participate in, any other collateral or security now or hereafter held by a Secured Party and
(ii) any right of contribution such Grantor may have against any other guarantor of the Obligations. Each Grantor further agrees that, to the extent the waiver of its rights of subrogation, reimbursement, indemnification and contribution as set
forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Grantor may have against any other Grantor or against any other collateral or
security, and any rights of contribution such Grantor may have against any such guarantor, shall be junior and subordinate to any rights a Secured Party may have against the other Grantors, to all right, title and interest a Secured Party may have
in any such other collateral or security, and to any right a Secured Party, may have against any such guarantor. 
  

 23 








 (e) No Secured Party shall have any obligation to disclose or discuss with any Grantor
its assessment, or such Grantor’s assessment, of the financial condition of any other Grantor. Each Grantor has adequate means to obtain information from the other Grantors on a continuing basis concerning the financial condition of the other
Grantors and their ability to perform their obligations under the Purchase Agreement and the Related Documents, and such Grantor assumes the responsibility for being and keeping informed of the financial condition of the other Grantors and of all
circumstances bearing upon the risk of nonpayment of the Obligations. Each Grantor hereby waives and relinquishes any duty on the part of a Secured Party to disclose any matter, fact or thing relating to the business, operations or condition of the
other Grantors now known or hereafter known by a Secured Party.

 EXHIBIT C 
 GUARANTY 
 This Guaranty is entered into as of May 18, 2009 by AlgoRx Pharmaceuticals,
Inc., a Delaware corporation (the “Guarantor”), in favor of and for the benefit of Arcion Therapeutics, Inc., a Delaware corporation (together with its successors and assignees, the “Beneficiary”) under that certain
Secured Note Purchase Agreement, dated as of May 18, 2009, by and among Anesiva, Inc., a Delaware corporation (the “Company”), and the Beneficiary (said Secured Note Purchase Agreement, as it may hereafter be amended,
supplemented or otherwise modified from time to time, being the “Purchase Agreement;” capitalized terms defined therein and not otherwise defined herein being used herein as therein defined). 
 1. Guaranty. (a) In order to induce the Beneficiary to extend credit to the Company pursuant to the Purchase Agreement,
the Guarantor irrevocably and unconditionally guaranties, as primary obligor and not merely as surety, the due and punctual payment in full of all Guarantied Amounts (as hereinafter defined) when the same shall become due, whether at stated
maturity, by acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code). The term “Guarantied Amounts” is used herein in
its most comprehensive sense and includes any and all obligations of Company in respect of notes, advances, borrowings, loans, debts, interest, fees, costs, expenses (including, without limitation, legal fees and expenses of counsel and allocated
costs of internal counsel), indemnities and liabilities of whatsoever nature now or hereafter made, incurred or created, whether absolute or contingent, liquidated or unliquidated, whether due or not due, and however arising under or in connection
with the Purchase Agreement, the Notes, this Guaranty and the other Related Documents, including those arising under successive borrowing transactions under the Purchase Agreement which shall either continue such obligations of the Company or from
time to time renew them after they have been satisfied. 
 The Guarantor acknowledges that the Guarantied Amounts are being
incurred for and will inure to the benefit of the Guarantor. 
 Any returns on any portion of the Guarantied Amounts that
accrues after the commencement of any proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of the Company (or, if returns on any portion of the Guarantied Amounts ceases
to accrue by operation of law by reason of the commencement of said proceeding, such returns as would have accrued on such portion of the Guarantied Amounts if said proceeding had not been commenced) shall be included in the Guarantied Amounts
because it is the intention of the Guarantor and the Beneficiary that the Guarantied Amounts should be determined without regard to any rule of law or order that may relieve the Company of any portion of such Guarantied Amounts. 







 In the event that all or any portion of the Guarantied Amounts is paid by the Company,
the obligations of the Guarantor hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) is rescinded or recovered directly or indirectly from the
Beneficiary as a preference, fraudulent transfer or otherwise, and any such payments that are so rescinded or recovered shall constitute Guarantied Amounts. 
 Subject to the other provisions of this Section 1, upon the failure of the Company to pay any of the Guarantied Amounts when and as
the same shall become due, the Guarantor will upon demand pay, or cause to be paid, in cash, to the Beneficiary, an amount equal to the aggregate of the unpaid Guarantied Amounts. Such payments shall be made in accordance with the applicable
provisions of the Purchase Agreement. 
 (b) Anything contained in this Guaranty to the contrary notwithstanding, the
obligations of the Guarantor under this Guaranty and the other Related Documents shall be limited to a maximum aggregate amount equal to the largest amount that would not render its obligations hereunder subject to avoidance as a fraudulent transfer
or conveyance under Section 548 of Title 11 of the United States Code or any applicable provisions of comparable state or foreign law (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other
liabilities of the Guarantor, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws (specifically excluding, however, any liabilities of the Guarantor (x) in respect of intercompany indebtedness to the Company or other
affiliates of the Company to the extent that such indebtedness would be discharged in an amount equal to the amount paid by the Guarantor hereunder and (y) under any guaranty of subordinated indebtedness which guaranty contains a limitation as
to maximum amount similar to that set forth in this Section 1(b), pursuant to which the liability of the Guarantor hereunder is included in the liabilities taken into account in determining such maximum amount) and after giving effect as assets
to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation, reimbursement, indemnification or contribution of the Guarantor pursuant to applicable law or pursuant to the terms of any
agreement. 
 (c) The Guarantor under this Guaranty, and each guarantor under other guaranties, if any, relating to the
Purchase Agreement (the “Related Guaranties”) that contain a contribution provision similar to that set forth in this Section 1(c), together desire to allocate among themselves (collectively, the “Contributing
Guarantors”), in a fair and equitable manner, their obligations arising under this Guaranty and the Related Guaranties. Accordingly, in the event any payment or distribution is made on any date by the Guarantor under this Guaranty or a
guarantor under a Related Guaranty, the Guarantor or such other guarantor shall be entitled to a contribution from each of the other Contributing Guarantors in the maximum amount permitted by law so as to maximize the aggregate amount of the
Guarantied Amounts paid to the Beneficiary. 
 2. Guaranty Absolute; Continuing Guaranty. The obligations of the
Guarantor hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance that constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guarantied Amounts.
In furtherance of the foregoing, and without limiting the generality thereof, the Guarantor agrees that: (a) this Guaranty is a guaranty of payment when due and not of collectibility; (b) the 

  

 2 








 
Beneficiary may enforce this Guaranty upon the occurrence and during the continuance of an Event of Default under the Purchase Agreement notwithstanding the
existence of any dispute between the Company and the Beneficiary with respect to the existence of such event; (c) the obligations of the Guarantor hereunder are independent of the obligations of the Company under the Purchase Agreement and the
Related Documents and the obligations of any other guarantor of obligations of the Company and a separate action or actions may be brought and prosecuted against the Guarantor whether or not any action is brought against the Company or any of such
other guarantors and whether or not the Company is joined in any such action or actions; and (d) the Guarantor’s payment of a portion, but not all, of the Guarantied Amounts shall in no way limit, affect, modify or abridge the
Guarantor’s liability for any portion of the Guarantied Amounts that has not been paid. This Guaranty is a continuing guaranty and shall be binding upon the Guarantor and its successors and assigns, and the Guarantor irrevocably waives any
right (including, without limitation, any such right arising under California Civil Code Section 2815) to revoke this Guaranty as to future transactions giving rise to any Guarantied Amounts. 
 3. Actions by Beneficiary. The Beneficiary may from time to time, without notice or demand and without affecting the validity or
enforceability of this Guaranty or giving rise to any limitation, impairment or discharge of the Guarantor’s liability hereunder, (a) renew, extend, accelerate or otherwise change the time, place, manner or terms of payment of the

had notice or knowledge of any of them: (a) any failure to assert or enforce or agreement not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or


  

 3 








 
demand or any right, power or remedy with respect to the Guarantied Amounts or any agreement relating thereto, or with respect to any other guaranty of or
security for the payment of the Guarantied Amounts; (b) any waiver or modification of, or any consent to departure from, any of the terms or provisions of the Purchase Agreement, any of the Related Documents or any agreement or instrument

or delay to do any other act or thing, that may or might in any manner or to any extent vary the risk of the Guarantor as an obligor in respect of the Guarantied Amounts. 
 5. Waivers. The Guarantor waives, for the benefit of the Beneficiary: (a) any right to require the Beneficiary, as a condition
of payment or performance by the Guarantor, to (i) proceed against the Company, any other guarantor of the Guarantied Amounts or any other Person, (ii) proceed against or exhaust any security held from the Company, any other guarantor of
the Guarantied Amounts or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of the Beneficiary in favor of the Company or any other Person, or (iv) pursue any other remedy
in the power of the Beneficiary; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of the Company including, without limitation, any defense based on or arising out of the lack of validity
or the unenforceability of the Guarantied Amounts or any agreement or instrument relating thereto or by reason of the cessation of the liability of the Company from any cause other than payment in full of the Guarantied Amounts; (c) any defense
based upon any statute or rule of law that provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon the Beneficiary’s errors or

 As used in this paragraph, any reference to “the principal” includes the
Company, and any reference to “the creditor” includes the Beneficiary. In accordance with Section 2856 of the California Civil Code, the Guarantor waives any and all rights and defenses available to the Guarantor by reason of Sections
2787 to 2855, inclusive, of the California Civil Code, including, without limitation, any and all rights or defenses the Guarantor may have because the Guarantied Amounts are or may be secured by real property. This means, among other things:
(1) the creditor may collect from the Guarantor without first foreclosing on any real or personal property collateral pledged by the principal and (2) if the creditor forecloses on any real property collateral pledged by the principal:
(A) the amount of the Guarantied Amounts may be reduced only by the price for which the collateral is sold at the foreclosure sale, even if the collateral is worth more than the sale price and (B) the creditor may collect from the
Guarantor even if the creditor, by foreclosing on the real property collateral, has destroyed any right the Guarantor may have to collect from the principal. This is an unconditional and irrevocable waiver of any right and defenses the Guarantor may
have because the Guarantied Amounts are secured by real property. These rights and defenses include, but are not limited to, any rights and defenses based upon Section 580a, 580b, 580d or 726 of the California Code of Civil Procedure. The
Guarantor also waives all rights and defenses arising out of an election of remedies by the creditor, even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a Guarantied Amount, has destroyed the
Guarantor’s rights of subrogation and reimbursement against the principal by the operation of Section 580d of the Code of Civil Procedure or otherwise; and even though that election of remedies by the creditor, such as nonjudicial
foreclosure with respect to security for an obligation of any other guarantor of any of the Guarantied Amounts, has destroyed the Guarantor’s rights of contribution against such other guarantor. No other provision of this Guaranty shall be
construed as limiting the generality of any of the covenants and waivers set forth in this paragraph. 
 6.
Guarantor’s Rights of Subrogation, Contribution, Etc.; Subordination of Other Obligations. Until the Guarantied Amounts shall have been paid in full, the Guarantor shall withhold exercise of (a) any claim, right or remedy, direct or
indirect, that the Guarantor now has or may hereafter have against the Company or any of its assets in connection with this Guaranty or the performance by the Guarantor of its obligations hereunder, in each case whether such claim, right or remedy
arises in equity, under contract, by statute (including without limitation under California Civil Code Section 2847, 2848 or 2849), under common law or otherwise and including, without limitation, (i) any right of subrogation,
reimbursement or indemnification that the Guarantor now has or may hereafter have against the Company; (ii) any right to enforce, or to participate in, any claim, right or remedy that the Beneficiary now has or may hereafter have against the
Company; and (iii) any benefit of, and any right to participate in, any collateral or security now or hereafter held by the Beneficiary and (b) any right of contribution the Guarantor now has or may hereafter have against any other
guarantor of 

  

 5 








 
any of the Guarantied Amounts. The Guarantor further agrees that, to the extent the agreement to withhold the exercise of its rights of subrogation,
reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification the Guarantor may have against the
Company or against any collateral or security, and any rights of contribution the Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights the Beneficiary may have against the Company, to all right, title
and interest the Beneficiary may have in any such collateral or security, and to any right the Beneficiary may have against such other guarantor. 
 Any indebtedness of the Company now or hereafter held by the Guarantor is subordinated in right of payment to the Guarantied Amounts, and any such indebtedness of the Company to the Guarantor collected or received by
the Guarantor after an Event of Default has occurred and is continuing, and any amount paid to the Guarantor on account of any subrogation, reimbursement, indemnification or contribution rights referred to in the preceding paragraph when all
Guarantied Amounts have not been paid in full, shall be held in trust for the Beneficiary and shall forthwith be paid over to the Beneficiary to be credited and applied against the Guarantied Amounts. 
 7. Expenses. The Guarantor agrees to pay, or cause to be paid, on demand, and to save the Beneficiary harmless against liability
for, (i) any and all costs and expenses (including fees, costs of settlement and disbursements of counsel and allocated costs of internal counsel) incurred or expended by the Beneficiary in connection with the enforcement of or preservation of
any rights under this Guaranty and (ii) any and all costs and expenses (including those arising from rights of indemnification) required to be paid by the Guarantor under the provisions of the Purchase Agreement or any Related Document.

 8. Financial Condition of Company. The Beneficiary shall not have any obligation, and the Guarantor waives any duty
on the part of the Beneficiary, to disclose or discuss with the Guarantor its assessment, or the Guarantor’s assessment, of the financial condition of the Company or any matter or fact relating to the business, operations or condition of the
Company. The Guarantor has adequate means to obtain information from the Company on a continuing basis concerning the financial condition of the Company and its ability to perform its obligations under the Purchase Agreement and the Related
Documents, and the Guarantor assumes the responsibility for being and keeping informed of the financial condition of the Company and of all circumstances bearing upon the risk of nonpayment of the Guarantied Amounts. 
 9. Representations and Warranties. The Guarantor makes, for the benefit of the Beneficiary, each of the representations and
warranties made in the Purchase Agreement by the Company as to the Guarantor, its assets, financial condition, operations, organization, legal status, business and the Related Documents to which it is a party. 
  

 6 








 10. Covenants. The Guarantor agrees that, so long as any part of the Guarantied
Amounts shall remain unpaid, the Guarantor will, unless the Majority Investors shall otherwise consent in writing, perform or observe, and cause its Subsidiaries to perform or observe, all of the terms, covenants and agreements that the Purchase
Agreement and the Related Documents state that the Company is to cause the Guarantor and such Subsidiaries to perform or observe. 
 11. Set Off. In addition to any other rights the Beneficiary may have under law or in equity, if any amount shall at any time be due and owing by the Guarantor to the Beneficiary under this Guaranty, the Beneficiary is authorized at
any time or from time to time, without notice (any such notice being expressly waived), to set off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of
deposit, whether matured or unmatured) and any other indebtedness of the Beneficiary owing to the Guarantor and any other property of the Guarantor held by the Beneficiary to or for the credit or the account of the Guarantor against and on account
of the Guarantied Amounts and liabilities of the Guarantor to the Beneficiary under this Guaranty. 
 12. Amendments and
Waivers. No amendment, modification, termination or waiver of any provision of this Guaranty, and no consent to any departure by the Guarantor therefrom, shall in any event be effective without the written concurrence of the Majority Investors
and, in the case of any such amendment or modification, the Guarantor. Any such waiver or consent shall be effective only in the specific instance and for the specific purpose for which it was given. Any amendment or waiver effected in accordance
with this Section 12 shall be binding upon the Beneficiary and each other holder of any Notes purchased under the Purchase Agreement at the time outstanding, each future holder of all such Notes and the Guarantor. 
 13. Miscellaneous. It is not necessary for the Beneficiary to inquire into the capacity or powers of the Guarantor or the Company
or the officers, directors or any agents acting or purporting to act on behalf of any of them. 
 The rights, powers and
remedies given to the Beneficiary by this Guaranty are cumulative and shall be in addition to and independent of all rights, powers and remedies given to the Beneficiary by virtue of any statute or rule of law or in the Purchase Agreement or any of
the Related Documents or any agreement between the Guarantor and the Beneficiary or between the Company and the Beneficiary. Any forbearance or failure to exercise, and any delay by the Beneficiary in exercising, any right, power or remedy hereunder
shall not impair any such right, power or remedy or be construed to be a waiver thereof, nor shall it preclude the further exercise of any such right, power or remedy. 
 In case any provision in or obligation under this Guaranty shall be invalid, illegal or unenforceable in any jurisdiction, the validity,
legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected or impaired thereby. 
 THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE GUARANTOR AND THE BENEFICIARY HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE
CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF CALIFORNIA, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES.

successors and assigns. 
 ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST THE GUARANTOR ARISING OUT OF OR RELATING TO THIS GUARANTY
MAY BE BROUGHT IN ANY STATE COURT OF COMPETENT JURISDICTION IN SAN FRANCISCO COUNTY, STATE OF CALIFORNIA, OR IN ANY FEDERAL COURT OF COMPETENT JURISDICTION IN THE NORTHERN DISTRICT FOR THE STATE OF CALIFORNIA, AND BY EXECUTION AND DELIVERY OF THIS
GUARANTY THE GUARANTOR ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS AND IRREVOCABLY AGREES TO BE BOUND
BY ANY JUDGMENT RENDERED THEREBY IN CONNECTION WITH THIS GUARANTY. The Guarantor agrees that service of all process in any such proceeding in any such court may be made by registered or certified mail, return receipt requested, to the Guarantor at
its address set forth below its signature hereto, such service being acknowledged by the Guarantor to be sufficient for personal jurisdiction in any action against the Guarantor in any such court and to be otherwise effective and binding service in
every respect. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of the Beneficiary to bring proceedings against the Guarantor in the courts of any other jurisdiction.
