 SECTION 2. THE LOAN 

2.1 [Reserved] 

2.2 Term Loan. 

(a) Advances. 

(i) Subject to the terms and conditions of this Agreement, during the Tranche 1 Draw Period, the Lenders will severally (and
not jointly) make in an amount not to exceed its respective Term Commitment, and Borrower agrees to draw, Term Loan Advances of up to Twenty Five Million Dollars ($25,000,000), which such first Term Loan Advance, Borrower agrees to draw on the
Closing Date in a minimum amount of $5,000,000 and thereafter in minimum increments of $5,000,000 (each a “Tranche 1 Advance”). 

  
 16 












 (ii) Subject to the terms and conditions of this Agreement, during the
Tranche 2 Draw Period, Borrower may request and the Lenders shall severally (and not jointly) make additional Term Loan Advances in a principal amount of up to Ten Million Dollars ($10,000,000), in minimum increments of $5,000,000 (each a
“Tranche 2 Advance”). 
 (iii) Subject to the terms and conditions of this Agreement, during the Tranche 3 Draw
Period, Borrower may request and the Lenders shall severally (and not jointly) make additional Term Loan Advances in a principal amount of up to Fifteen Million Dollars ($15,000,000), in minimum increments of $5,000,000 (each, a “Tranche 3
Advance”). 
 (iv) Subject to the terms and conditions of this Agreement, and conditioned on approval by the
Lenders’ investment committee in its sole and unfettered discretion, on or before December 15, 2024, Borrower may request an additional Term Loan Advance in an aggregate principal amount up to Twenty Five Million Dollars ($25,000,000) (the
“Tranche 4 Advance”). 
 (v) The aggregate outstanding Term Loan Advances may be up to the Maximum Term Loan
Amount. 
 (b) Advance Request. To obtain a Term Loan Advance, Borrower shall complete, sign and deliver an Advance Request
(at least one (1) Business Day before the Closing Date and at least five (5) Business Days before each Advance Date other than the Closing Date) to Agent. The Lenders shall fund the Term Loan Advance in the manner requested by the
Advance Request provided that each of the conditions precedent to such Term Loan Advance is satisfied as of the requested Advance Date. 

(c) Interest. 

(i) Term Loan Interest Rate. The principal balance of Term Loan Advances shall bear interest thereon from such Advance Date at
the Term Loan Interest Rate based on a year consisting of 360 days, with interest computed daily based on the actual number of days elapsed. The Term Loan Interest Rate will float and change on the day the prime rate changes from time to time. 

(d) Payment. Borrower will pay interest on each Term Loan Advance on the first Business Day of each month, beginning the month
after the Advance Date. Borrower shall commence repayment of the aggregate Term Loan principal balance that is outstanding on the day immediately preceding the Amortization Date, in equal monthly installments of principal and interest (mortgage
style) beginning on the Amortization Date and continuing on the first Business Day of each month thereafter until the Secured Obligations (other than inchoate indemnity obligations) are repaid. The entire Term Loan principal balance and all accrued
but unpaid interest hereunder, shall be due and payable on the Term Loan Maturity Date. Borrower shall make all payments under this Agreement without setoff, recoupment or deduction and regardless of any counterclaim or defense, except for Taxes
required to be deducted or withheld under applicable Law, which shall be governed by Addendum 1. If a payment hereunder becomes due and payable on a day that is not a Business Day, the due date thereof shall be the immediately preceding Business
Day. The Lenders will initiate debit entries to the Borrower’s account as authorized on the ACH Authorization (i) on each payment date of all periodic obligations payable to the Lenders under each Term Loan Advance and (ii) reasonable
and documented out-of-pocket legal fees and costs incurred by Agent or the Lenders in connection with Section 11.12 of this Agreement; provided that, with respect
to clause (i) above, in the event that the Lenders or Agent 

  
 17 












 
informs Borrower that the Lenders will not initiate a debit entry to Borrower’s account for a certain amount of the periodic obligations due on a specific payment date, Borrower shall pay to
the Lenders such amount of periodic obligations in full in immediately available funds on such payment date; provided, further, that, with respect to clause (i) above, if the Lenders or Agent informs Borrower that the Lenders will not initiate
a debit entry as described above later than the date that is three (3) Business Days prior to such payment date, Borrower shall pay to the Lenders such amount of periodic obligations in full in immediately available funds on the date that is
three (3) Business Days after the date on which the Lenders or Agent notifies Borrower of such; provided, further, that, with respect to clause (ii) above, in the event that the Lenders or Agent informs Borrower that the Lenders will not
initiate a debit entry to Borrower’s account for certain amount of such out-of-pocket legal fees and costs incurred by Agent or the Lenders, Borrower shall pay to
the Lenders such amount in full in immediately available funds within three (3) Business Days. 
 2.3 Maximum Interest.
Notwithstanding any provision in this Agreement or any other Loan Document, it is the parties’ intent not to contract for, charge or receive interest at a rate that is greater than the maximum rate permissible by law that a court of competent
jurisdiction shall deem applicable hereto (which under the laws of the State of California shall be deemed to be the laws relating to permissible rates of interest on commercial loans) (the “Maximum Rate”). If a court of competent
jurisdiction shall finally determine that Borrower has actually paid to the Lenders an amount of interest in excess of the amount that would have been payable if all of the Secured Obligations had at all times borne interest at the Maximum Rate,
then such excess interest actually paid by Borrower shall be applied as follows: first, to the payment of the Secured Obligations consisting of the outstanding principal; second, after all principal is repaid, to the payment of the Lenders’
accrued interest, costs, expenses, professional fees and any other Secured Obligations; and third, after all Secured Obligations are repaid, the excess (if any) shall be refunded to Borrower. 

2.4 Default Interest. In the event any payment is not paid on the scheduled payment date, an amount equal to four percent (4%)
of the past due amount shall be payable on demand. In addition, upon the occurrence and during the continuation of an Event of Default hereunder, all Secured Obligations, including principal, interest, compounded interest, and professional fees,
shall bear interest at a rate per annum equal to the rate set forth in Section 2.2(c) plus four percent (4%) per annum. In the event any interest is not paid when due hereunder, delinquent interest shall be added to principal and shall bear
interest on interest, compounded at the rate set forth in Section 2.2(c) or Section 2.4, as applicable. 
 2.5
Prepayment. At its option upon at least seven (7) Business Days prior written notice to Agent (which such notice may be conditioned on a concurrent transaction closing), Borrower may prepay all, but not less than all, of the outstanding
Advances by paying the entire principal balance, all accrued and unpaid interest thereon, together with a prepayment charge equal to the following percentage of the Advance amount being prepaid: with respect to each Advance, if such Advance amounts
are prepaid in any of the first twelve (12) months following the Closing Date, 3.00%; on or after twelve (12) months but prior to twenty four (24) months, 2.00%; on or after twenty four (24) months but prior to thirty six
(36) months, 1.00% and on or after thirty-six (36) months, 0.00% (each, a “Prepayment Charge”). If at any time Borrower elects to make a prepayment, and at such time, there are outstanding
Advances under multiple Tranches, the Prepayment Charge shall be determined by applying the amount of such prepayment in the following order: first, to the outstanding principal amount (and accrued but unpaid interest thereon) of Advances
outstanding under the Tranche with the latest initial funding date; second, to the outstanding principal amount (and accrued but unpaid interest thereon) of Advances outstanding 

  
 18 












 
under the Tranche with the next latest initial funding date and so on until the entire principal balance of all Advances made hereunder (and all accrued but unpaid interest thereon) is paid in
full. Borrower agrees that the Prepayment Charge is a reasonable calculation of the Lenders’ lost profits in view of the difficulties and impracticality of determining actual damages resulting from an early repayment of the Advances.
Borrower shall prepay the outstanding amount of all principal and accrued interest through the prepayment date the Prepayment Charge upon the occurrence of a Change in Control or any other prepayment hereunder. Notwithstanding the foregoing, Agent
and the Lenders agree to waive the Prepayment Charge if Agent and the Lenders (in their sole and absolute discretion) agree in writing to refinance the Advances prior to the Term Loan Maturity Date. Any amounts paid under this Section shall be
applied by Agent to the then unpaid amount of any Secured Obligations (including principal and interest) in such order and priority as Agent may choose in its sole discretion. For the avoidance of doubt, if a payment hereunder becomes due and
payable on a day that is not a Business Day, the due date thereof shall be the immediately preceding Business Day. 
 2.6 End
of Term Charge. On the earliest to occur of (i) the Term Loan Maturity Date, (ii) the date that Borrower prepays the outstanding Secured Obligations (other than any inchoate indemnity obligations and any other obligations which, by their
terms, are to survive the termination of this Agreement) in full, or (iii) the date that the Secured Obligations become due and payable, Borrower shall pay the Lenders a charge of 6.00% of the principal amount of funded Term Loan Advances (the
“End of Term Charge”). Notwithstanding the required payment date of such End of Term Charge, the applicable pro rata portion of the End of Term Charge shall be deemed earned by the Lenders as of each date a Term Loan Advance is made. For
the avoidance of doubt, if a payment hereunder becomes due and payable on a day that is not a Business Day, the due date thereof shall be the immediately preceding Business Day. 

2.7 Pro Rata Treatment. Each payment (including prepayment) on account of any fee and any reduction of the Term Loans shall be
made pro rata according to the Term Commitments of the relevant Lender. 
 2.8 Taxes; Increased Costs. The Borrower, the
Agent and the Lenders each hereby agree to the terms and conditions set forth on Addendum 1 attached hereto. 
 2.9 Treatment
of Prepayment Charge and End of Term Charge. Borrower agrees that any Prepayment Charge and any End of Term Charge payable shall be presumed to be the liquidated damages sustained by each Lender as the result of the early termination, and Borrower
agrees that it is reasonable under the circumstances currently existing and existing as of the Closing Date. The Prepayment Charge and the End of Term Charge shall also be payable in the event the Secured Obligations (and/or this Agreement) are
satisfied or released by foreclosure (whether by power of judicial proceeding), deed in lieu of foreclosure, or by any other means. Borrower expressly waives (to the fullest extent it may lawfully do so) the provisions of any present or future
statute or law that prohibits or may prohibit the collection of the foregoing Prepayment Charge and End of Term Charge in connection with any such acceleration. Borrower agrees (to the fullest extent that each may lawfully do so): (a) each of the
Prepayment Charge and the End of Term Charge is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (b) each of the Prepayment Charge and the End of Term Charge
shall be payable notwithstanding the then prevailing market rates at the time payment is made; (c) there has been a course of conduct between the Lenders and Borrower giving specific consideration in this transaction for such agreement to pay
the Prepayment Charge and the End of Term Charge as a charge (and not interest) in the event of prepayment or acceleration; (d) Borrower shall be estopped from claiming differently than as agreed to in this paragraph. Borrower expressly
acknowledges that their agreement to pay each of the Prepayment Charge and the End of Term Charge to the Lenders as herein described was on the Closing Date and continues to be a material inducement to the Lenders to provide the Term Loans. 

  
 19 












 SECTION 3. SECURITY INTEREST 

3.1 As security for the prompt and complete payment when due (whether on the payment dates or otherwise) of all the Secured
Obligations, Borrower grants to Agent a security interest in all of Borrower’s right, title, and interest in, to and under all of Borrower’s personal property and other assets including without limitation the following (except as set forth

foregoing; provided, however, that the Collateral shall include all Accounts and General Intangibles that consist of rights to payment and proceeds from the sale, licensing or disposition of all or any part,
or rights in, the Intellectual Property (the “Rights to Payment”). Notwithstanding the foregoing, if a judicial authority (including a U.S. Bankruptcy Court) holds that a security interest in the underlying Intellectual Property is
necessary to have a security interest in the Rights to Payment, then the Collateral shall automatically, and effective as of the date of this Agreement, include the Intellectual Property to the extent necessary to permit perfection of Agent’s
security interest in the Rights to Payment. 
 3.2 Notwithstanding the broad grant of the security interest set forth in
Section 3.1, above, the Collateral shall not include (a) nonassignable licenses or contracts, which by their terms require the consent of the licensor thereof or another party (but only to the extent such prohibition on transfer is
enforceable under applicable law, including, without limitation, Sections 9406, 9407 and 9408 of the UCC), (b) any Excluded Accounts, (c) with respect to Equity Interests in Foreign Subsidiaries and FSHCOs held directly by Borrower, more than

challenging or questioning Borrower’s ownership in any material Intellectual Property (or written notice of any claim challenging or questioning the ownership in any licensed Intellectual Property of the owner thereof) or suggesting that any
third party has any claim of legal or beneficial ownership with respect thereto nor, to Borrower’s knowledge, is there a reasonable basis for any such claim. Neither Borrower’s use of its Intellectual Property nor the production and sale

are, and at all times within the last three years have been, in compliance with all applicable Healthcare Laws, except where failures to so comply would not, whether individually or in the aggregate, reasonably be expected to have a Material Adverse
Effect. Borrower has not received any written notification, correspondence, or any other communication from any Governmental Authority asserting non-compliance by, or liability of, Borrower or any Subsidiary
under any applicable Healthcare Laws, except where such non-compliance would not, whether individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Borrower is not a party to
or has any ongoing reporting obligations pursuant to or under any order by a Governmental Authority or corporate integrity agreements, deferred or non-prosecution agreements, monitoring agreements, consent
decrees, settlement orders, plans of correction or similar agreements with or imposed by any Governmental Authority. Neither Borrower or any Subsidiary, nor any officers, employees or, to the knowledge of Borrower, agents of Borrower or any

 25 












 (b) Borrower and each Subsidiary has obtained and maintained all Permits,
including any Permits required pursuant to any applicable Healthcare Laws, and all of such Permits are in full force and effect, except where failures to possess or maintain the same, would not, whether individually or in the aggregate, reasonably
be expected to have a Material Adverse Effect. Borrower and each Subsidiary has fulfilled and performed all of its material obligations with respect to the Permits, and, to the knowledge of Borrower, no event has occurred which allows, or after
notice or lapse of time would allow, revocation or termination thereof or result in any other impairment of the rights of the holder of any Permit, except where such revocations, terminations or impairments would not, whether individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. 
 (c) All clinical or preclinical studies, tests or
trials that have been or are being conducted by or on behalf of, or sponsored by, Borrower or any Subsidiary, or in which Borrower’s or any Subsidiary’s products or product candidates have participated, and which have been or will be
submitted to the FDA or other regulatory authorities in connection with applications for Permits, were and, if still pending, are being conducted in compliance in all material respects with all applicable Healthcare Laws. No investigational new drug
application or other allowance to commence a clinical trial filed with or submitted to the FDA or other Governmental Authority by or on behalf of Borrower or any Subsidiary has been terminated or suspended, and neither the FDA nor any applicable
Governmental Authority has commenced, or to the knowledge of Borrower, threatened to initiate, any action to place a clinical hold order on, or otherwise terminate, delay or suspend, any proposed or ongoing clinical investigation conducted or
proposed to be conducted by or on behalf of Borrower or any Subsidiary. 
 SECTION 6. INSURANCE; INDEMNIFICATION 

6.1 Coverage. Borrower shall cause to be carried and maintained commercial general liability insurance, on an occurrence form,
against risks customarily insured against in Borrower’s line of business. Such risks shall include the risks of bodily injury, including death, property damage, personal injury, advertising injury, and contractual liability per the terms of the
indemnification agreement found in Section 6.3. Borrower must maintain a minimum of $2,000,000 of commercial general liability insurance for each occurrence. Borrower has and agrees to maintain a minimum of $2,000,000 of directors’ and
officers’ insurance for each occurrence and $5,000,000 in the aggregate. So long as there are any Secured Obligations (other than any inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination
of this Agreement) outstanding, Borrower shall also cause to be carried and maintained insurance upon the Collateral, insuring against all risks of physical loss or damage howsoever caused, in an amount not less than the full replacement cost of the
Collateral, provided that such insurance may be subject to standard exceptions and deductibles. If Borrower fails to obtain the insurance called for by this Section 6.1 or fails to pay any premium thereon or fails to pay any other amount which
Borrower is obligated to pay under this Agreement or any other Loan Document or which may be required to preserve the Collateral, Agent may obtain such insurance or make such payment, and all amounts so paid by Agent are immediately due and payable,
bearing interest at the then highest rate applicable to the Secured Obligations, and secured by the Collateral. Agent will make reasonable efforts to provide Borrower with notice of Agent obtaining such insurance at the time it is obtained or
within a reasonable time thereafter. No payments by Agent are deemed an agreement to make similar payments in the future or Agent’s waiver of any Event of Default. 

  
 26 












 6.2 Certificates. Borrower shall deliver to Agent certificates of insurance
that evidence Borrower’s compliance with its insurance obligations in Section 6.1 and the obligations contained in this Section 6.2. Borrower’s insurance certificate shall state Agent (shown as “Hercules Capital, Inc., as
Agent”) is an additional insured for commercial general liability, a lenders loss payable for all risk property damage insurance, subject to the insurer’s approval, and a lenders loss payable for property insurance and additional insured
for liability insurance for any future insurance that Borrower may acquire from such insurer. Attached to the certificates of insurance will be additional insured endorsements for liability and lender’s loss payable endorsements for all risk
property damage insurance. All certificates of insurance will provide for a minimum of thirty (30) days advance written notice to Agent of cancellation (other than cancellation for non-payment of
premiums, for which ten (10) days’ advance written notice shall be sufficient) or any other change adverse to Agent’s interests. Any failure of Agent to scrutinize such insurance certificates for compliance is not a waiver of any of
Agent’s rights, all of which are reserved. Borrower shall provide Agent with copies of each insurance policy, and upon entering or amending any insurance policy required hereunder, Borrower shall provide Agent with copies of such policies and
shall promptly deliver to Agent updated insurance certificates with respect to such policies. 
 6.3 Indemnity. Borrower
agrees to indemnify and hold Agent, the Lenders and their officers, directors, employees, agents, in-house attorneys, representatives and shareholders (each, an “Indemnified Person”) harmless from
and against any and all claims, costs, expenses, damages and liabilities (including such claims, costs, expenses, damages and liabilities based on liability in tort, including strict liability in tort), including reasonable and documented out-of-pocket attorneys’ fees and disbursements and other costs of investigation or defense (including those incurred upon any appeal) (collectively,
“Liabilities”), that may be instituted or asserted against or incurred by such Indemnified Person as the result of credit having been extended, suspended or terminated under this Agreement and the other Loan Documents or the administration
of such credit, or in connection with or arising out of the transactions contemplated hereunder and thereunder, or any actions or failures to act in connection therewith, or arising out of the disposition or utilization of the Collateral, excluding
in all cases Liabilities to the extent resulting solely from any Indemnified Person’s gross negligence or willful misconduct. This Section 6.3 shall not apply with respect to Taxes other than any Taxes that represent losses, claims,
damages, etc. arising from any non-Tax claim. In no event shall any Indemnified Person be liable on any theory of liability for any special, indirect, consequential or punitive damages (including any loss of
profits, business or anticipated savings). This Section 6.3 shall survive the repayment of indebtedness under, and otherwise shall survive the expiration or other termination of, this Agreement.

SECTION 10. REMEDIES 

10.1 General. Upon the occurrence of any one or more Events of Default, Agent may, and at the direction of the Required Lenders
shall, accelerate and demand payment of all or any part of the Secured Obligations together with a Prepayment Charge and declare them to be immediately due and payable (provided, that upon the occurrence of an Event of Default of the type described
in Section 9.5, all of the Secured Obligations (including, without limitation, the Prepayment Charge and the End of Term Charge) shall automatically be accelerated and made due and payable, in each case without any further notice or act).
Borrower hereby irrevocably appoints Agent as its lawful attorney-in-fact to: (a) exercisable following the occurrence of an Event of Default, (i) sign
Borrower’s name on any invoice or bill of lading for any account or drafts against account debtors; (ii) demand, collect, sue, and give releases to any account debtor for monies due, settle and adjust disputes and claims about the accounts
directly with account debtors, and compromise, prosecute, or defend any action, claim, case, or proceeding about any Collateral (including filing a claim or voting a claim in any bankruptcy case in Agent’s or Borrower’s name, as Agent may
elect); (iii) make, settle, and adjust all claims under Borrower’s insurance policies; (iv) pay, contest or settle any Lien, charge, encumbrance, security interest, or other claim in or to the Collateral, or any judgment based thereon, or
otherwise take any action to terminate or discharge the same; (v) transfer the Collateral into the name of Agent or a third party as the UCC permits; and (vi) receive, open and dispose of mail addressed to Borrower; and (b) regardless
of whether an Event of Default has occurred, (i) endorse Borrower’s name on any checks, payment instruments, or other forms of payment or security; and (ii) notify all account debtors to pay Agent directly. Borrower hereby
appoints Agent as its lawful attorney-in-fact to sign Borrower’s name on any documents necessary to perfect or continue the perfection of Agent’s security
interest in the Collateral regardless of whether an Event of Default has occurred until all Secured Obligations (other than any inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this
Agreement) have been satisfied in full and the Loan Documents have been terminated. Agent’s foregoing appointment as Borrower’s attorney in fact, and all of Agent’s rights and powers, coupled with an interest, are irrevocable
until all Secured Obligations (other than any inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been fully repaid and performed and the Loan


  
 36 












 
Documents have been terminated. Agent may, and at the direction of the Required Lenders shall, exercise all rights and remedies with respect to the Collateral under the Loan Documents or
otherwise available to it under the UCC and other applicable law, including the right to release, hold, sell, lease, liquidate, collect, realize upon, or otherwise dispose of all or any part of the Collateral and the right to occupy, utilize,
process and commingle the Collateral. All Agent’s rights and remedies shall be cumulative and not exclusive. 
 10.2
Collection; Foreclosure. Upon the occurrence and during the continuance of any Event of Default, Agent may, and at the direction of the Required Lenders shall, at any time or from time to time, apply, collect, liquidate, sell in one or more sales,
lease or otherwise dispose of, any or all of the Collateral, in its then condition or following any commercially reasonable preparation or processing, in such order as Agent may elect. Any such sale may be made either at public or private sale at
its place of business or elsewhere. Borrower agrees that any such public or private sale may occur upon ten (10) calendar days’ prior written notice to Borrower. Agent may require Borrower to assemble the Collateral and make it available
to Agent at a place designated by Agent that is reasonably convenient to Agent and Borrower. The proceeds of any sale, disposition or other realization upon all or any part of the Collateral shall be applied by Agent in the following order of
priorities: 
 First, to Agent and the Lenders in an amount sufficient to pay in full Agent’s and the Lenders’ reasonable costs and
professionals’ and advisors’ fees and expenses as described in Section 11.12; 
 Second, to the Lenders in an amount equal to
the then unpaid amount of the Secured Obligations (including principal, interest, and the Default Rate interest), in such order and priority as Agent may choose in its sole discretion; and 

Finally, after the full and final payment in Cash of all of the Secured Obligations (other than inchoate indemnity obligations), to any
creditor holding a junior Lien on the Collateral, or to Borrower or its representatives or as a court of competent jurisdiction may direct. 
 Agent shall
be deemed to have acted reasonably in the custody, preservation and disposition of any of the Collateral if it complies with the obligations of a secured party under the UCC. 

10.3 No Waiver. Agent shall be under no obligation to marshal any of the Collateral for the benefit of Borrower or any other
Person, and Borrower expressly waives all rights, if any, to require Agent to marshal any Collateral. 
 10.4 Cumulative
Remedies. The rights, powers and remedies of Agent hereunder shall be in addition to all rights, powers and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers and remedies provided
herein shall not be construed as a waiver of or election of remedies with respect to any other rights, powers and remedies of Agent. 

SECTION 11. MISCELLANEOUS 

11.1 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective
and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under such law, such provision shall be ineffective only to the extent and duration of such prohibition or invalidity, without invalidating the
remainder of such provision or the remaining provisions of this Agreement.

 11.3 Entire Agreement; Amendments. 

  
 38 












 (a) This Agreement and the other Loan Documents constitute the entire
agreement and understanding of the parties hereto in respect of the subject matter hereof and thereof, and supersede and replace in their entirety any prior proposals, term sheets, non-disclosure or
confidentiality agreements, letters, negotiations or other documents or agreements, whether written or oral, with respect to the subject matter hereof or thereof (including Agent’s revised proposal letter dated March 9, 2022 and the Non-Disclosure Agreement). 
 (b) Neither this Agreement, any other Loan Document, nor any
terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 11.3(b). The Required Lenders and Borrower party to the relevant Loan Document may, or, with the written consent of the
Required Lenders, the Agent and the Borrower party to the relevant Loan Document may, from time to time, (i) enter into written amendments, supplements or modifications hereto and to the other Loan Documents for the purpose of adding any
provisions to this Agreement or the other Loan Documents or changing in any manner the rights of the Lenders or of the Borrower hereunder or thereunder or (ii) waive, on such terms and conditions as the Required Lenders or the Agent, as the
case may be, may specify in such instrument, any of the requirements of this Agreement or the other Loan Documents or any Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification
shall (A) forgive the principal amount or extend the final scheduled date of maturity of any Loan, extend the scheduled date of any amortization payment in respect of any Term Loan, reduce the stated rate of any interest (or fee payable
hereunder) or extend the scheduled date of any payment thereof, in each case without the written consent of each Lender directly affected thereby; (B) eliminate or reduce the voting rights of any Lender under this Section 11.3(b) without
the written consent of such Lender; (C) reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other Loan
Documents, release all or substantially all of the Collateral or release a Borrower from its obligations under the Loan Documents, in each case without the written consent of all Lenders; or (D) amend, modify or waive any provision of
Section 11.18 or Addendum 3 without the written consent of the Agent. Any such waiver and any such amendment, supplement or modification shall apply equally to each Lender and shall be binding upon Borrower, the Lender, the Agent and all future
holders of the Loans. 
 11.4 No Strict Construction. The parties hereto have participated jointly in the negotiation and
drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no presumption or burden of proof shall arise favoring or
disfavoring any party by virtue of the authorship of any provisions of this Agreement. 
 11.5 No Waiver. The powers
conferred upon Agent and the Lenders by this Agreement are solely to protect its rights hereunder and under the other Loan Documents and its interest in the Collateral and shall not impose any duty upon Agent or the Lenders to exercise any such
powers. No omission or delay by Agent or the Lenders at any time to enforce any right or remedy reserved to it, or to require performance of any of the terms, covenants or provisions hereof by Borrower at any time designated, shall be a waiver of
any such right or remedy to which Agent or the Lenders is entitled, nor shall it in any way affect the right of Agent or the Lenders to enforce such provisions thereafter. 

11.6 Survival. All agreements, representations and warranties contained in this Agreement and the other Loan Documents or in
any document delivered pursuant hereto or thereto shall be for the benefit of Agent and the Lenders and shall survive the execution and delivery of this Agreement. Sections 6.3, 8.1 (except as otherwise provided in Section 8.1), 11.14, 11.15
and 11.17 shall survive the termination of this Agreement. 
  

  
 39 












 11.7 Successors and Assigns. The provisions of this Agreement and the other
Loan Documents shall inure to the benefit of and be binding on Borrower and its permitted assigns (if any). Borrower shall not assign its obligations under this Agreement or any of the other Loan Documents without Agent’s express prior written
consent, and any such attempted assignment shall be void and of no effect. Agent and the Lenders may assign, transfer, or endorse its rights hereunder and under the other Loan Documents without prior notice to Borrower, and all of such rights shall
inure to the benefit of Agent’s and the Lenders’ successors and assigns; provided that as long as no Event of Default has occurred and is continuing, neither Agent nor any Lender may assign, transfer or endorse its rights hereunder or
under the Loan Documents to any party that is a direct competitor of Borrower (as reasonably determined by Agent), it being acknowledged that in all cases, any transfer to an Affiliate of any Lender or Agent shall be allowed. Notwithstanding the
foregoing, (x) in connection with any assignment by a Lender as a result of a forced divestiture at the request of any regulatory agency, the restrictions set forth herein shall not apply and Agent and the Lenders may assign, transfer or
indorse its rights hereunder and under the other Loan Documents to any Person or party and (y) in connection with a Lender’s own financing or securitization transactions, the restrictions set forth herein shall not apply and Agent and the
Lenders may assign, transfer or indorse its rights hereunder and under the other Loan Documents to any Person or party providing such financing or formed to undertake such securitization transaction and any transferee of such Person or party upon
the occurrence of a default, event of default or similar occurrence with respect to such financing or securitization transaction; provided that no such sale, transfer, pledge or assignment under this clause (y) shall release such Lender from
any of its obligations hereunder or substitute any such Person or party for such Lender as a party hereto until Agent shall have received and accepted an effective assignment agreement from such Person or party in form satisfactory to Agent
executed, delivered and fully completed by the applicable parties thereto, and shall have received such other information regarding such assignee as Agent reasonably shall require. The Agent, acting solely for this purpose as an agent of the
Borrower, shall maintain at one of its offices in the United States a register for the recordation of the names and addresses of the Lender(s), and the Term Commitments of, and principal amounts (and stated interest) of the Loans owing to, each
Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Agent and the Lender(s) shall treat each Person whose name is recorded in
the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior
notice. 
 11.8 Participations. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each participant and the principal amounts (and stated interest) of each participant’s interest in the Loans
or other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any participant or any
information relating to a participant’s interest in any commitments, loans, its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such commitment, loan, letter of
credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and
such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Agent (in its
capacity as Agent) shall have 

  
 40 












 
no responsibility for maintaining a Participant Register. Borrower agrees that each participant shall be entitled to the benefits of the provisions in Addendum 1 attached hereto (subject to the
requirements and limitations therein, including the requirements under Section 7 of Addendum 1 attached hereto (it being understood that the documentation required under Section 7 of Addendum 1 attached hereto shall be delivered to the
participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 11.7; provided that such participant shall not be entitled to receive any greater payment under Addendum 1 attached
hereto, with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a change in law that occurs after the participant acquired
the applicable participation. 
 11.9 Governing Law. This Agreement and the other Loan Documents have been negotiated and
delivered to Agent and the Lenders in the State of California, and shall have been accepted by Agent and the Lenders in the State of California. Payment to Agent and the Lenders by Borrower of the Secured Obligations is due in the State of
California. This Agreement and the other Loan Documents shall be governed by, and construed and enforced in accordance with, the laws of the State of California, excluding conflict of laws principles that would cause the application of laws of any
other jurisdiction. 
 11.10 Consent to Jurisdiction and Venue. All judicial proceedings (to the extent that the reference
requirement of Section 11.11 is not applicable) arising in or under or related to this Agreement or any of the other Loan Documents may be brought in any state or federal court located in the State of California. By execution and delivery of
this Agreement, each party hereto generally and unconditionally: (a) consents to nonexclusive personal jurisdiction in Santa Clara County, State of California; (b) waives any objection as to jurisdiction or venue in Santa Clara County,
State of California; (c) agrees not to assert any defense based on lack of jurisdiction or venue in the aforesaid courts; and (d) irrevocably agrees to be bound by any judgment rendered thereby in connection with this Agreement or the
other Loan Documents. Service of process on any party hereto in any action arising out of or relating to this Agreement shall be effective if given in accordance with the requirements for notice set forth in Section 11.2, and shall be deemed
effective and received as set forth in Section 11.2. Nothing herein shall affect the right to serve process in any other manner permitted by law or shall limit the right of either party to bring proceedings in the courts of any other
jurisdiction. 
 11.11 Mutual Waiver of Jury Trial / Judicial Reference. 

(a) Because disputes arising in connection with complex financial transactions are most quickly and economically resolved by an
experienced and expert Person and the parties wish applicable state and federal laws to apply (rather than arbitration rules), the parties desire that their disputes be resolved by a judge applying such applicable laws. EACH OF BORROWER, AGENT AND
THE LENDERS SPECIFICALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY OF ANY CAUSE OF ACTION, CLAIM, CROSS-CLAIM, COUNTERCLAIM, THIRD PARTY CLAIM OR ANY OTHER CLAIM (COLLECTIVELY, “CLAIMS”) ASSERTED BY BORROWER AGAINST AGENT, THE LENDERS
OR THEIR RESPECTIVE ASSIGNEE OR BY AGENT, THE LENDERS OR THEIR RESPECTIVE ASSIGNEE AGAINST BORROWER. This waiver extends to all such Claims, including Claims that involve Persons other than Agent, Borrower and the Lenders; Claims that arise out of
or are in any way connected to the relationship among Borrower, Agent and the Lenders; and any Claims for damages, breach of contract, tort, specific performance, or any equitable or legal relief of any kind, arising out of this Agreement, any other
Loan Document. 

  
 41 












 (b) If the waiver of jury trial set forth in Section 11.11(a) is
ineffective or unenforceable, the parties agree that all Claims shall be resolved by reference to a private judge sitting without a jury, pursuant to Code of Civil Procedure Section 638, before a mutually acceptable referee or, if the parties
cannot agree, a referee selected by the Presiding Judge of the Santa Clara County, California. Such proceeding shall be conducted in Santa Clara County, California, with California rules of evidence and discovery applicable to such proceeding. 

(c) In the event Claims are to be resolved by judicial reference, either party may seek from a court identified in
Section 11.10, any prejudgment order, writ or other relief and have such prejudgment order, writ or other relief enforced to the fullest extent permitted by law notwithstanding that all Claims are otherwise subject to resolution by judicial
reference. 
 11.12 Professional Fees. Borrower promises to pay Agent’s and the Lenders’ fees and expenses
necessary to finalize the loan documentation, including but not limited to reasonable attorneys’ fees, UCC searches, filing costs, and other miscellaneous expenses. In addition, Borrower promises to pay any and all reasonable attorneys’
and other professionals’ fees and expenses incurred by Agent and the Lenders after the Closing Date in connection with or related to: (a) the Loan; (b) the administration, collection, or enforcement of the Loan; (c) the amendment
or modification of the Loan Documents; (d) any waiver, consent, release, or termination under the Loan Documents; (e) the protection, preservation, audit, field exam, sale, lease, liquidation, or disposition of Collateral or the exercise
of remedies with respect to the Collateral; (f) any legal, litigation, administrative, arbitration, or out of court proceeding in connection with or related to Borrower or the Collateral, and any appeal or review thereof; and (g) any
bankruptcy, restructuring, reorganization, assignment for the benefit of creditors, workout, foreclosure, or other action related to Borrower, the Collateral, the Loan Documents, including representing Agent or the Lenders in any adversary
proceeding or contested matter commenced or continued by or on behalf of Borrower’s estate, and any appeal or review thereof. 

11.13 Confidentiality. Agent and the Lenders acknowledge that certain items of Collateral and information provided to Agent and
the Lenders by Borrower are confidential and proprietary information of Borrower, if and to the extent such information either (x) is marked as confidential by Borrower at the time of disclosure, or (y) should reasonably be understood to
be confidential (the “Confidential Information”). Accordingly, Agent and the Lenders agree that any Confidential Information it may obtain in the course of acquiring, administering, or perfecting Agent’s security interest in the
Collateral shall not be disclosed to any other Person or entity in any manner whatsoever, in whole or in part, without the prior written consent of Borrower, except that Agent and the Lenders may disclose any such information: (a) to its
Affiliates and its partners, investors, lenders, directors, officers, employees, agents, advisors, counsel, accountants, counsel, representative and other professional advisors if Agent or the Lenders in their sole discretion determines that any
such party should have access to such information in connection with such party’s responsibilities in connection with the Loan or this Agreement and, provided that such recipient of such Confidential Information either (i) agrees to be
bound by the confidentiality provisions of this paragraph or (ii) is otherwise subject to confidentiality restrictions that reasonably protect against the disclosure of Confidential Information; (b) if such information is generally
available to the public or to the extent such information becomes publicly available other than as a result of a breach of this Section or becomes available to Agent or any Lender, or any of their respective Affiliates on a non-confidential basis from a source other than the Borrower; (c) if required or appropriate in any report, statement or testimony submitted to any governmental authority having or claiming to have jurisdiction
over Agent or the Lenders and any rating agency; (d) if required or appropriate in response to any summons or subpoena or in connection with any litigation, to the extent permitted or deemed advisable by Agent’s or the Lenders’
counsel; (e) to 

  
 42 












 
comply with any legal requirement or law applicable to Agent or the Lenders or demanded by any governmental authority; (f) to the extent reasonably necessary in connection with the exercise
of, or preparing to exercise, or the enforcement of, or preparing to enforce, any right or remedy under any Loan Document (including Agent’s sale, lease, or other disposition of Collateral after default), or any action or proceeding relating to
any Loan Document; (g) to any participant or assignee of Agent or the Lenders or any prospective participant or assignee, provided, that such participant or assignee or prospective participant or assignee is subject to confidentiality
restrictions that reasonably protect against the disclosure of Confidential Information; (h) to any investor or potential investor (and each of their respective Affiliates or clients) in the Agent or the Lenders (or each of their respective
Affiliates); provided that such investor, potential investor, Affiliate or client is subject to confidentiality obligations with respect to the Confidential Information; (i) otherwise to the extent consisting of general portfolio information
that does not identify Borrower; or (j) otherwise with the prior consent of Borrower; provided, that any disclosure made in violation of this Agreement shall not affect the obligations of Borrower or any of its Affiliates or any guarantor under
this Agreement or the other Loan Documents. Agent’s and the Lenders’ obligations under this Section 11.13 shall supersede all of their respective obligations under the Non-Disclosure Agreement.

 11.14 Assignment of Rights. Borrower acknowledges and understands that Agent or the Lenders may, subject to
Section 11.7, sell and assign all or part of its interest hereunder and under the Loan Documents to any Person or entity (an “Assignee”). After such assignment the term “Agent” or “Lender” as used in the Loan
Documents shall mean and include such Assignee, and such Assignee shall be vested with all rights, powers and remedies of Agent and the Lenders hereunder with respect to the interest so assigned; but with respect to any such interest not so
transferred, Agent and the Lenders shall retain all rights, powers and remedies hereby given. No such assignment by Agent or the Lenders shall relieve Borrower of any of its obligations hereunder. the Lenders agrees that in the event of any transfer
by it of the promissory note(s) (if any), it will endorse thereon a notation as to the portion of the principal of the promissory note(s), which shall have been paid at the time of such transfer and as to the date to which interest shall have been
last paid thereon. 
 11.15 Revival of Secured Obligations. This Agreement and the Loan Documents shall remain in full force
and effect and continue to be effective if any petition is filed by or against Borrower for liquidation or reorganization, if Borrower becomes insolvent or makes an assignment for the benefit of creditors, if a receiver or trustee is appointed for
all or any significant part of Borrower’s assets, or if any payment or transfer of Collateral is recovered from Agent or the Lenders. The Loan Documents and the Secured Obligations and Collateral security shall continue to be effective, or
shall be revived or reinstated, as the case may be, if at any time payment and performance of the Secured Obligations or any transfer of Collateral to Agent, or any part thereof is rescinded, avoided or avoidable, reduced in amount, or must
otherwise be restored or returned by, or is recovered from, Agent, the Lenders or by any obligee of the Secured Obligations, whether as a “voidable preference,” “fraudulent conveyance,” or otherwise, all as though such payment,
performance, or transfer of Collateral had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, avoided, avoidable, restored, returned, or recovered, the Loan Documents and the Secured Obligations shall be
deemed, without any further action or documentation, to have been revived and reinstated except to the extent of the full, final, and indefeasible payment to Agent or the Lenders in Cash. 

11.16 Counterparts. This Agreement and any amendments, waivers, consents or supplements hereto may be executed in any number of
counterparts, and by different parties hereto in separate counterparts, each of which when so delivered shall be deemed an original, but all of which counterparts shall constitute but one and the same instrument. 

  
 43 












 11.17 No Third Party Beneficiaries. No provisions of the Loan Documents are
intended, nor will be interpreted, to provide or create any third-party beneficiary rights or any other rights of any kind in any Person other than Agent, the Lenders and Borrower unless specifically provided otherwise herein, and, except as
otherwise so provided, all provisions of the Loan Documents will be personal and solely among Agent, the Lenders and the Borrower. 

11.18 Agency. Agent and each Lender hereby agree to the terms and conditions set forth on Addendum 3 attached hereto. Borrower
acknowledges and agrees to the terms and conditions set forth on Addendum 3 attached hereto. 
 11.19 Publicity. None of the
parties hereto nor any of its respective member businesses and Affiliates shall, without the other parties’ prior written consent (which shall not be unreasonably withheld or delayed), publicize or use (a) the other party’s name
(including a brief description of the relationship among the parties hereto), logo or hyperlink to such other parties’ web site, separately or together, in written and oral presentations, advertising, promotional and marketing materials, client
lists, public relations materials or on its web site (together, the “Publicity Materials”); (b) the names of officers of such other parties in the Publicity Materials; and (c) such other parties’ name, trademarks, servicemarks in
any news or press release concerning such party; provided however, notwithstanding anything to the contrary herein, no such consent shall be required (i) to the extent necessary to comply with the requests of any regulators, legal requirements
or laws applicable to such party, pursuant to any listing agreement with any national securities exchange (so long as such party provides prior notice to the other party hereto to the extent reasonably practicable) and (ii) to comply with
Section 11.13. 
 11.20 Electronic Execution of Certain Other Documents. The words “execution,”
“execute”, “signed,” “signature,” and words of like import in or related to any document to be signed in connection with this Agreement and the transactions contemplated hereby (including without limitation assignments,
assumptions, amendments, waivers and consents) shall be deemed to include electronic signatures, the electronic matching of assignment terms and contract formations on electronic platforms approved by the Agent, or the keeping of records in
electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable
law, including the Federal Electronic Signatures in Global and National Commerce Act, the California Uniform Electronic Transaction Act, or any other similar state laws based on the Uniform Electronic Transactions Act.

 ADDENDUM 1 to LOAN AND SECURITY AGREEMENT 

TAXES; INCREASED COSTS 
  

	1.	 Defined Terms. For purposes of this Addendum 1: 



 

	a.	 “Connection Income Taxes” means Other Connection Taxes that are imposed on or measured by net
income (however denominated) or that are franchise Taxes or branch profits Taxes. 


  

	b.	 “Excluded Taxes” means any of the following Taxes imposed on or with respect to a Recipient or
required to be withheld or deducted from a payment to a Recipient, (i) Taxes imposed on or measured by net income (however denominated), franchise Taxes, and branch profits Taxes, in each case, (A) imposed as a result of such Recipient
being organized under the laws of, or having its principal office or, in the case of any Lender, its applicable lending office located in, the jurisdiction imposing such Tax (or any political subdivision thereof) or (B) that are Other
Connection Taxes, (ii) in the case of a Lender, U.S. federal withholding Taxes imposed on amounts payable to or for the account of such Lender with respect to an applicable interest in a Loan or Term Commitment pursuant to a law in effect on
the date on which (A) such Lender acquires such interest in the Loan or Term Commitment or (B) such Lender changes its lending office, except in each case to the extent that, pursuant to Section 2 or Section 4 of this Addendum 1,
amounts with respect to such Taxes were payable either to such Lender’s assignor immediately before such Lender became a party hereto or to such Lender immediately before it changed its lending office, (iii) Taxes attributable to such
Recipient’s failure to comply with Section 7 of this Addendum 1 and (iv) any withholding Taxes imposed under FATCA. 


  

	c.	 “FATCA” means Sections 1471 through 1474 of the Code, as of the date of this Agreement (or any
amended or successor version that is substantively comparable and not materially more onerous to comply with), any current or future regulations or official interpretations thereof, any agreements entered into pursuant to Section 1471(b)(1) of
the Code, any intergovernmental agreements entered into in connection with any of the foregoing and any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement, treaty or convention among governmental
authorities and implementing such Sections of the Code. 


  

	d.	 “Foreign Lender” means a Lender that is not a U.S. Person. 



 

	e.	 “Indemnified Taxes” means (i) Taxes, other than Excluded Taxes, imposed on or with
respect to any payment made by or on account of any obligation of the Borrower under any Loan Document and (ii) to the extent not otherwise described in clause (i), Other Taxes. 



 

	f.	 “Other Connection Taxes” means, with respect to any Recipient, Taxes imposed as a result of a
present or former connection between such Recipient and the jurisdiction imposing such Tax (other than connections arising from such Recipient having executed, delivered, become a party to, performed its obligations under, received payments under,
received or perfected a security interest under, engaged in any other transaction pursuant to or enforced any Loan Document, or sold or assigned an interest in any Loan or Loan Document). 














	g.	 “Other Taxes” means all present or future stamp, court or documentary, intangible, recording,
filing or similar Taxes that arise from any payment made under, from the execution, delivery, performance, enforcement or registration of, from the receipt or perfection of a security interest under, or otherwise with respect to, any Loan Document,
except any such Taxes that are Other Connection Taxes imposed with respect to an assignment. 


  

	 	h.	 “Recipient” means the Agent or any Lender, as applicable. 



 

	 	i.	 “Withholding Agent” means the Borrower and the Agent. 



 

	2.	 Payments Free of Taxes. Any and all payments by or on account of any obligation of the Borrower under
any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable Withholding Agent) requires the deduction or
withholding of any Tax from any such payment by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant governmental
authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and
withholdings applicable to additional sums payable under this Section 2 or Section 4 of this Addendum 1) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.



  

	3.	 Payment of Other Taxes by Borrower. The Borrower shall timely pay to the relevant governmental authority
in accordance with applicable law, or at the option of the Agent timely reimburse it for the payment of, any Other Taxes. 


  

	4.	 Indemnification by Borrower. Without duplication of its obligations under Sections 2 or 3 of this
Addendum 1, the Borrower shall indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under Section 2
of this Addendum 1 or this Section 4) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any reasonable expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes were correctly or legally imposed or asserted by the relevant governmental authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on
its own behalf or on behalf of a Lender, shall be conclusive absent manifest error. In addition, the Borrower agrees to pay, and to save the Agent and any Lender harmless from, any and all liabilities with respect to, or resulting from any delay in
paying, any and all excise, sales or other similar taxes (excluding taxes imposed on or measured by the net income of the Agent or such Lender) that may be payable or determined to be payable with respect to any of the Collateral or this Agreement.



  

	5.	 Indemnification by the Lenders. Each Lender shall severally indemnify the Agent, within 10 days after
demand therefor, for (a) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so),
(b) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 11.8 of the Agreement relating to the maintenance of a Participant Register and (c) any Excluded Taxes attributable to such Lender, in each
case, that are payable or paid by the Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant
governmental authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any and all amounts at
any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any other source against any amount due to the Agent under this Section 5. 














	6.	 Evidence of Payments. As soon as practicable after any payment of Taxes by the Borrower to a
governmental authority pursuant to the provisions of this Addendum 1, the Borrower shall deliver to the Agent the original or a copy of a receipt issued by such governmental authority evidencing such payment, a copy of the return reporting such
payment or other evidence of such payment reasonably satisfactory to the Agent. 


  

	7.	 Status of Lenders. 



 

	 	a.	 Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made
under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will
permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Agent, shall deliver such other documentation prescribed by applicable law or reasonably
requested by the Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding
two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 7(b)(i), 7(b)(ii) and 7(b)(iv) of this Addendum 1) shall not be required if in the Lender’s reasonable judgment
such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender. 



 

	 	b.	 Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person,



  

	 	i.	 any Lender that is a U.S. Person shall deliver to the Borrower and the Agent on or prior to the date on which
such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed copies of IRS Form W-9 certifying that such Lender is
exempt from U.S. federal backup withholding tax; 


  

	 	ii.	 any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent
(in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent),
whichever of the following is applicable: 


  

	 	A.	 in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a
party (x) with respect to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN or IRS Form
W-8BEN-E establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty and (y) with
respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or IRS Form W-8BEN-E establishing an exemption
from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other income” article of such tax treaty; 














	 	B.	 executed copies of IRS Form W-8ECI; 



 

	 	C.	 in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under
Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit J-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A)
of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section 871(h)(3)(B) of the Code, or a “controlled foreign corporation” related to the Borrower as described in Section 881(c)(3)(C) of
the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form
W-8BEN-E; or 


  

	 	D.	 to the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY, accompanied by IRS Form W-8ECI, IRS Form W-8BEN, IRS Form
W-8BEN-E, a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-2 or Exhibit
J-3, IRS Form W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one or more
direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance Certificate substantially in the form of Exhibit J-4 on
behalf of each such direct and indirect partner; 


  

	 	iii.	 any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent
(in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent),
executed copies of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable
law to permit the Borrower or the Agent to determine the withholding or deduction required to be made; and 


  

	 	iv.	 if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed
by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Agent at
the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such
additional documentation reasonably requested by the Borrower or the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s
obligations under FATCA or to determine the amount, if any, to deduct and withhold from such payment. Solely for purposes of this clause (iv), “FATCA” shall include any amendments made to FATCA after the date of this Agreement.















	 	c.	 Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or
inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so. For purposes of this Section 7 of Addendum 1, Agent shall be treated as a Lender and
required to deliver documentation to Borrower as if it were a Lender. 


  

	8.	 Treatment of Certain Refunds. If any party determines, in its sole discretion exercised in good faith,
that it has received a refund of any Taxes as to which it has been indemnified pursuant to the provisions of this Addendum 1 (including by the payment of additional amounts pursuant to the provisions of this Addendum 1), it shall pay to the
indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under the provisions of this Addendum 1 with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant governmental authority with respect to such refund). Such indemnifying
party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 8 (plus any penalties, interest or other charges imposed by the relevant governmental authority) in the event
that such indemnified party is required to repay such refund to such governmental authority. Notwithstanding anything to the contrary in this Section 8, in no event will the indemnified party be required to pay any amount to an indemnifying
party pursuant to this Section 8 the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to
indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 8 shall not be construed to
require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person. 



 

	9.	 Increased Costs. If any change in applicable law shall subject any Recipient to any Taxes (other than
(A) Indemnified Taxes, (B) Taxes described in clauses (ii) through (iv) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, commitments, or other obligations, or its deposits,
reserves, other liabilities or capital attributable thereto, and the result shall be to increase the cost to such Recipient of making, converting to, continuing or maintaining any Term Loan or of maintaining its obligation to make any such Loan, or
to reduce the amount of any sum received or receivable by such Recipient (whether of principal, interest or any other amount), then, upon the request of such Recipient, the Borrower will pay to such Recipient such additional amount or amounts as
will compensate such Recipient for such additional costs incurred or reduction suffered. 


  

	10.	 Survival. Each party’s obligations under the provisions of this Addendum 1 shall survive the
resignation or replacement of the Agent or any assignment of rights by, or the replacement of, a Lender, the termination of the Term Commitments and the repayment, satisfaction or discharge of all obligations under any Loan Document.














 ADDENDUM 2 to LOAN AND SECURITY AGREEMENT 

[Reserved] 











 ADDENDUM 3 to LOAN AND SECURITY AGREEMENT 

Agent and Lender Terms

This Joinder Agreement (the “Joinder Agreement”) is made and dated as of [ ], 20[ ], and is entered into by and
between__________________., a ___________ corporation (“Subsidiary”), and HERCULES CAPITAL, INC., a Maryland corporation (as “Agent”). 

RECITALS 
 A.
Subsidiary’s Affiliate, [ ] (“Company”) [has entered/desires to enter] into that certain Loan and Security Agreement dated April 1, 2022, with the several banks and other financial institutions or entities from time to time party
thereto as lender (collectively, the “Lenders”) and the Agent, as such agreement may be amended (the “Loan Agreement”), together with the other agreements executed and delivered in connection therewith; 

B. Subsidiary acknowledges and agrees that it will benefit both directly and indirectly from Company’s execution of the Loan Agreement
and the other agreements executed and delivered in connection therewith; 
 AGREEMENT 

NOW THEREFORE, Subsidiary and Agent agree as follows: 
  

	1.	 The recitals set forth above are incorporated into and made part of this Joinder Agreement. Capitalized terms
not defined herein shall have the meaning provided in the Loan Agreement. 


  

	2.	 By signing this Joinder Agreement, Subsidiary shall be bound by the terms and conditions of the Loan Agreement
the same as if it were the Borrower (as defined in the Loan Agreement) under the Loan Agreement, mutatis mutandis, provided however, that (a) with respect to (i) Section 5.1 of the Loan Agreement, Subsidiary represents that it is an
entity duly organized, legally existing and in good standing under the laws of [ ], (b) neither Agent nor the Lenders shall have any duties, responsibilities or obligations to Subsidiary arising under or related to the Loan Agreement or the other
Loan Documents, (c) that if Subsidiary is covered by Company’s insurance, Subsidiary shall not be required to maintain separate insurance or comply with the provisions of Sections 6.1 and 6.2 of the Loan Agreement, and (d) that as
long as Company satisfies the requirements of Section 7.1 of the Loan Agreement, Subsidiary shall not have to provide Agent separate Financial Statements. To the extent that Agent or the Lenders has any duties, responsibilities or obligations
arising under or related to the Loan Agreement or the other Loan Documents, those duties, responsibilities or obligations shall flow only to Company and not to Subsidiary or any other Person or entity. By way of example (and not an exclusive list):
(i) Agent’s providing notice to Company in accordance with the Loan Agreement or as otherwise agreed among Company, Agent and the Lenders shall be deemed provided to Subsidiary; (ii) a Lender’s providing an Advance to Company shall be
deemed an Advance to Subsidiary; and (iii) Subsidiary shall have no right to request an Advance or make any other demand on the Lenders. 


  

	3.	 Subsidiary agrees not to certificate its equity securities without Agent’s prior written consent, which
consent may be conditioned on the delivery of such equity securities to Agent in order to perfect Agent’s security interest in such equity securities. 


  

	4.	 Subsidiary acknowledges that it benefits, both directly and indirectly, from the Loan Agreement, and hereby
waives, for itself and on behalf on any and all successors in interest (including without limitation any assignee for the benefit of creditors, receiver, bankruptcy trustee or itself as
debtor-in-possession under any bankruptcy proceeding) to the fullest extent provided by law, any and all claims, rights or defenses to the enforcement of this Joinder
Agreement on the basis that (a) it failed to receive adequate consideration for the execution and delivery of this Joinder Agreement or (b) its obligations under this Joinder Agreement are avoidable as a fraudulent conveyance.















	5.	 As security for the prompt, complete and indefeasible payment when due (whether on the payment dates or
otherwise) of all the Secured Obligations, Subsidiary grants to Agent a security interest in all of Subsidiary’s right, title, and interest in and to the Collateral.
