LOAN AND SECURITY AGREEMENT

This LOAN AND SECURITY AGREEMENT (this “Agreement”) is entered into as of April 26, 2024, by and among BANC OF CALIFORNIA, a California state-chartered bank (“Bank”); TURNSTONE BIOLOGICS CORP., a Delaware corporation (“Parent” or “Borrower”); and MYST THERAPEUTICS, LLC, a Delaware limited liability company(“Myst”; and together with each other Person that becomes a guarantor hereunder from time to time (each a “Guarantor” and, collectively, “Guarantors”; Borrower and Guarantors are each referred to herein as a “Loan Party” and, collectively, as “Loan Parties”).

RECITALS

Borrower wishes to obtain credit from time to time from Bank, and Bank desires to extend credit to Borrower. This Agreement sets forth the terms on which Bank will advance credit to Borrower and Borrower will repay the amounts owing to Bank.

AGREEMENT

The parties agree as follows:

1.
DEFINITIONS AND CONSTRUCTION.

1.1 Definitions. As used in this Agreement, all capitalized terms shall have the definitions set forth on Exhibit A. Any term used in the Code and not defined herein shall have the meaning given to the term in the Code.

1.2 Accounting Terms. Any accounting term not specifically defined on Exhibit A shall be construed in accordance with GAAP, and all calculations shall be made in accordance with GAAP (except for non-compliance with FAS 123R in monthly reporting). The term “financial statements” shall include the accompanying notes and schedules.

2.
LOAN AND TERMS OF PAYMENT.

2.1 Credit Extensions.

(a) Promise to Pay. Borrower promises to pay to Bank, in lawful money of the United States of America, the aggregate unpaid principal amount of all Credit Extensions made by Bank to Borrower, together with interest on the unpaid principal amount of such Credit Extensions at rates in accordance with the terms hereof.

(b) Advances Under Non-Formula Revolving Line.

(i) Amount. Subject to and upon the terms and conditions of this Agreement, (A) Borrower may request Non-Formula Advances in an aggregate outstanding principal amount not to exceed the Non-Formula Revolving Line, less any amounts reserved under the Ancillary Services Sublimit, and (B) amounts borrowed pursuant to this Section 2.1(b) may be repaid and reborrowed at any time prior to the Non-Formula Revolving Maturity Date, at which time all Non-Formula Advances under this Section 2.1(b) shall be immediately due and payable. Borrower may prepay any Non-Formula Advances without penalty or premium.

(ii) Form of Request. Whenever Borrower desires a Non- Formula Advance, Borrower will notify Bank (which notice shall be irrevocable) by email (or, if permitted by Bank, through the use of an E-System)no later than 3:30 p.m. Eastern time (2:30 p.m. Eastern time for wire transfers) on the Business Day that the Non-Formula


Advance is to be made. Each such notification shall be given by a Loan Advance/Paydown Request Form in substantially the form of Exhibit C. Bank is authorized to make Non-Formula Advances under this Agreement, based upon instructions received from an Authorized Officer, or without instructions if in Bank’s reasonable discretion such Non-Formula Advances are necessary to meet Obligations which have become due and remain unpaid. Bank shall be entitled to rely on any notice given by a person whom Bank reasonably believes to be an Authorized Officer, and Borrower shall indemnify and hold Bank harmless for any damages, losses, costs, and expenses suffered by Bank as a result of such reliance. Bank will credit the amount of Non-Formula Advances made under this Section 2.1(b) to Borrower’s deposit account.

(iii) Ancillary Services Sublimit. Subject to the terms and conditions of this Agreement, at any time and from time to time from the date hereof through the Business Day immediately prior to the Non-Formula Revolving Maturity Date, Loan Parties may request the provision of Ancillary Services from Bank. The aggregate limits of Ancillary Services shall not exceed the Ancillary Services Sublimit, provided that availability under the Non-Formula Revolving Line will be reduced by (i) the Letter of Credit Exposure, (ii) the aggregate limits of corporate credit card services provided to Borrower, (iii) the total amount of any Automated Clearing House processing reserves, (iv) the applicable Foreign Exchange Reserve Percentage, and (v) any other reserves taken by Bank in connection with other treasury management services requested by a Loan Party and approved by Bank. In addition, Bank may, in its reasonable discretion, charge as Non-Formula Advances any amounts that become due or owing to Bank or for which Bank becomes liable in connection with the provision of Ancillary Services. The terms and conditions (including repayment and fees) of such Ancillary Services shall be subject to the terms and conditions of Bank’s standard forms of application and agreement for the applicable Ancillary Services, which the applicable Loan Party hereby agrees to execute.

(iv) Collateralization of Obligations Extending Beyond Maturity. Borrower shall take, and shall cause each other Loan Party to take, such actions as Bank may reasonably request to cause its obligations with respect to any Ancillary Services to be secured to Bank’s reasonable satisfaction as of the Non-Formula Revolving Maturity Date. If Borrower has not secured to Bank’s reasonable satisfaction Loan Parties’ obligations with respect to any Ancillary Services by the Non-Formula Revolving Maturity Date, then, effective as of such date, the balance in any of Borrower’s deposit accounts held by Bank and the certificates of deposit or time deposit accounts issued by Bank in Borrower’s name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or liquidation of such certificates or accounts), shall automatically secure such obligations to the extent of the then continuing or outstanding Ancillary Services. Borrower authorizes Bank to hold such balances in pledge and to decline to honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the applicable Ancillary Services are outstanding or continue.

2.2 Overadvances. If the aggregate amount of the outstanding Non-Formula Advances exceeds the Non-Formula Revolving Line at any time, Borrower shall immediately pay to Bank, in Cash, the amount of such excess.

2.3 Interest Rates, Payments, and Calculations.

(a) Interest Rates.

(i) Non-Formula Advances. Except as set forth in Section 2.3(b), the Non-Formula Advances shall bear interest, on the outstanding daily balance thereof, at a


variable annual rate equal to the greater of: (A) the Prime Rate then in effect; or (B) four and twenty-five hundredths percent (4.25%).

(b) Late Fee; Default Rate. If any payment is not made within 15 days after the date such payment is due, Borrower shall pay Bank a late fee equal to the lesser of (i) 3% of the amount of such unpaid amount or (ii) the maximum amount permitted to be charged under applicable law. After the occurrence and during the continuance of an Event of Default, all Obligations shall bear interest, upon notice of such increase given by Bank, at a rate equal to three percentage points above the interest rate applicable immediately prior to the occurrence of the Event of Default (such rate, the “Default Rate”); provided that, from and after the occurrence of any Event of Default described in Section 8.5, such increase shall be automatic and without the requirement of any notice from Bank. In all such events, and notwithstanding the date on which application of the Default Rate is communicated to Borrower, the Default Rate may be accrued (at the election of Bank) from the initial date of any Event of Default until all existing Events of Default are waived in writing in accordance with the terms of this Agreement.

(c) Payments. Interest under the Non-Formula Revolving Line shall be due and payable on the first calendar day of each month during the term hereof. Borrower authorizes Bank, at Bank’s option, to charge all interest, all Bank Expenses, all Periodic Payments, and any other amounts due and owing in accordance with the terms of this Agreement against any of Borrower’s deposit accounts at Bank or against the Non-Formula Revolving Line, in which case those amounts shall thereafter accrue interest at the rate then applicable hereunder. Any interest not paid when due shall be compounded by becoming a part of the Obligations, and such interest shall thereafter accrue interest at the rate then applicable hereunder.

(d) Computation. In the event that the Prime Rate is changed from time to time hereafter, the applicable rate of interest hereunder shall be increased or decreased, effective as of the day the Prime Rate is changed, by an amount equal to such change in the Prime Rate. All interest chargeable under the Loan Documents shall be computed on the basis of a 360- day year for the actual number of days elapsed.

2.4 Crediting Payments. When no Event of Default has occurred and is continuing, Bank shall credit a wire transfer of funds, check or other item of payment to such deposit account or Obligation as Borrower specifies. After the occurrence and during the continuance of an Event of Default, Bank shall have the right, in its sole discretion, to immediately apply any wire transfer of funds, check, or other item of payment Bank may receive to conditionally reduce Obligations, but such application of funds shall not be considered a payment on account unless such payment is of immediately available federal funds or unless and until such check or other item of payment is honored when presented for payment. Notwithstanding anything to the contrary contained herein, any wire transfer or payment received by Bank after 3:30 p.m. Eastern time shall be deemed to have been received by Bank as of the opening of business on the immediately following Business Day. Whenever any payment to Bank under the Loan Documents would otherwise be due (except by reason of acceleration) on a date that is not a Business Day, such payment shall instead be due on the next Business Day, and additional fees or interest, as the case may be, shall accrue and be payable for the period of such extension.

2.5 Fees. Borrower shall pay to Bank the following:

(a) Facility Fee. On or before the Closing Date, a nonrefundable facility fee of $50,000;

(b) Bank Expenses. On the Closing Date, all Bank Expenses incurred through the Closing Date; and, after the Closing Date, all Bank Expenses, as and when they become due;


(c) Success Fee. Upon a Success Fee Event, a one-time fee equal to the Success Fee Amount (such fee, the “Success Fee”). This Section 2.5(c) will survive any termination of this Agreement; provided that this Section 2.5(c) shall terminate on the tenth anniversary of the Closing Date if no Success Fee Event has occurred on or before that date. If this Agreement is terminated prior to payment of the Success Fee, Borrower shall give Bank written notice of the first Success Fee Event to occur thereafter and, if the Success Fee Event occurred on or before the tenth anniversary of the Closing Date, pay the Success Fee upon the closing of such Success Fee Event; and

(d) Early Termination Fee. Upon the termination of this Agreement, whether in connection with acceleration, prepayment in full, or otherwise, (a) at any time on or before the first anniversary of the Closing Date, a nonrefundable fee of $400,000 and (b) at any time after the first anniversary of the Closing Date but on or before the second anniversary of the Closing Date, a nonrefundable fee of $200,000. This Section 2.5(d)will survive any termination of this Agreement.

2.6 Term. This Agreement shall become effective on the Closing Date and, subject to Section 12.7, shall continue in full force and effect for so long as any Obligations (other than inchoate indemnity obligations and Ancillary Services that have been secured to Bank’s satisfaction pursuant to Section 2.1(b)(iv)) remain outstanding or Bank has any obligation to make Credit Extensions under this Agreement. Notwithstanding the foregoing, Bank shall have the right to terminate its obligation to make Credit Extensions under this Agreement immediately and without notice upon the occurrence and during the continuance of an Event of Default.

3.

The making of each Credit Extension shall be deemed to be a representation and warranty by Loan Parties on the date of such Credit Extension as to the accuracy of the facts referred to in this Section 3.2.

4.
CREATION OF SECURITYINTEREST.

4.1 Grant of Security Interest. Each Loan Party grants and pledges to Bank a continuing security interest in the Collateral to secure prompt repayment of any and all Obligations and to secure prompt performance by each Loan Party of each of its covenants and duties under the Loan Documents. Except for Permitted Liens or as disclosed in the Schedule, such security interest constitutes a valid, first-priority security interest in the presently existing Collateral and will constitute a valid, first-priority security interest in later-acquired Collateral. Each Loan Party also hereby agrees not to sell, transfer, assign, mortgage, pledge, lease, grant a security interest in, or encumber any of its Intellectual Property except for Permitted Liens. Notwithstanding any termination of this Agreement or of any filings undertaken related to Bank’s rights under the Code, Bank’s Lien on the Collateral shall remain in effect for so long as any Obligations (other than inchoate indemnity obligations and Ancillary Services that have been secured to Bank’s satisfaction pursuant to Section 2.1(b)(iv)) are outstanding.

4.2 Perfection of Security Interest. Each Loan Party authorizes Bank to file at any time financing statements, continuation statements, and amendments thereto that (a) either specifically describe the Collateral or describe the Collateral as all assets of such Loan Party of the kind pledged hereunder, and (b) contain any other information required by the Code for the sufficiency of filing office acceptance of any financing statement, continuation statement, or amendment, including whether such Loan Party is an organization, the type of organization and any organizational identification number issued to such Loan Party, if applicable. Loan Parties shall have possession of the Collateral, except where expressly otherwise provided in this Agreement or where Bank chooses to perfect its security interest by possession in addition to the filing of a financing statement. Where Collateral is in possession of a third-party bailee, each Loan Party shall take such steps as Bank


reasonably requests for Bank to (x) subject to Section 7.11 below, obtain an acknowledgment, in form and substance reasonably satisfactory to Bank, of the bailee that the bailee holds such Collateral for the benefit of Bank, and (y) obtain “control” of any Collateral consisting of investment property, deposit accounts, letter-of-credit rights or electronic chattel paper (as such items and the term “control” are defined in Revised Article 9 of the Code) by causing the securities intermediary or depositary institution or issuing bank to execute a control agreement in form and substance to Bank. No Loan Party will create any chattel paper without placing a legend on such chattel paper acceptable to Bank indicating that Bank has a security interest in such chattel paper. Loan Parties from time to time may deposit with Bank specific cash collateral to secure specific Obligations. Each Loan Party authorizes Bank to hold such specific balances in pledge and to decline to honor any drafts thereon or any request by a Loan Party or any other Person to pay or otherwise transfer any part of such balances for so long as the specific Obligations are outstanding. Each Loan Party shall take such other actions as Bank reasonably requests to perfect its security interests granted under this Agreement.

4.3 Pledge of Collateral. Each Loan Party hereby pledges, assigns and grants to Bank a security interest in all of the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or granted in connection therewith and all other cash and noncash proceeds of the foregoing, as security for the performance of the Obligations. Each Loan Party will deliver to Bank (a) on the Closing Date, the certificate or certificates for any then-certificated Shares, and (b) with respect to any Shares uncertificated as of the Closing Date, promptly upon certification, the certificate or certificates for such Shares, in each case accompanied by an instrument of assignment duly governing such Shares. The relevant Loan Party shall cause the books of each entity whose Shares are part of the Collateral and any transfer agent to reflect the pledge of the Shares. Upon the occurrence and during the continuance of an Event of Default hereunder, Bank may effect the transfer of any securities included in the Collateral (including but not limited to the Shares) into the name of Bank and may cause new certificates representing such securities to be issued in the name of Bank or its transferee. Unless an Event of Default has occurred and is continuing, each Loan Party shall be entitled to exercise any voting rights with respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such terms. All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and during the continuance of an Event of Default.

5.
REPRESENTATIONS AND WARRANTIES.

Each Loan Party represents and warrants as follows:

5.1 Due Organization and Qualification. Each Loan Party and each Subsidiary is duly existing under the laws of the state in which it is organized and qualified and licensed to do business in any state in which the conduct of its business or its ownership of property requires that it be so qualified, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect.

5.2 Due Authorization; No Conflict. The execution, delivery, and performance of the Loan Documents are within each Loan Party’s powers, have been duly authorized, and are not in conflict with nor constitute a breach of any provision contained in any Loan Party’s Certificate of Incorporation, Bylaws, or other governing document, as applicable, nor will they constitute an event of default under any material agreement by which a Loan Party is bound. No Loan Party is in default under any agreement by which it is bound, except to the extent such default would not reasonably be expected to cause a Material Adverse Effect.


5.3 Collateral. Each Loan Party has rights in or the power to transfer the Collateral, and its title to the Collateral is free and clear of Liens, adverse claims, and restrictions on transfer or pledge except for Permitted Liens. All Collateral is located solely in the United States. All Inventory is in all material respects of good and merchantable quality, free from all material defects, except for Inventory for which adequate reserves have been made. Except as set forth in the Schedule or as permitted by Section 6.6,no Loan Party’s Cash is maintained or invested with a Person other than Bank or Bank’s affiliates.

5.4 Intellectual Property. Each Loan Party is the sole owner of the intellectual property created or purchased by the applicable Loan Party, except for licenses granted by a Loan Party to its customers in the ordinary course of business and licenses constituting Permitted Liens. The intellectual property created, licensed or purchased by each Loan Party constitutes all intellectual property necessary for the conduct of such Loan Party’s business as now conducted and as presently proposed to be conducted. To the best of each Loan Party’s knowledge, each of the material Copyrights, Patents, and Trademarks created or purchased by the applicable Loan Party is valid and enforceable, and no part of the material intellectual property created or purchased by any Loan Party has been judged invalid or unenforceable, in whole or in part, and no claim has been made to any Loan Party that any part of the intellectual property created or purchased by any Loan Party violates the rights of any third party except to the extent such claim would not reasonably be expected to cause a Material Adverse Effect.

5.5 Name; Location of Chief Executive Office. Except as disclosed in the Schedule, no Loan Party has done business under any name other than that specified on the signature page hereof, and each Loan Party’s exact legal name is as set forth in the first paragraph of this Agreement. The chief executive office of each Loan Party is located at the address indicated in Article 10 hereof.

5.6 Litigation. Except as set forth in the Schedule, there are no actions or proceedings pending by or against any Loan Party or any Subsidiary before any court or administrative agency in which a likely adverse decision would reasonably be expected to have a Material Adverse Effect.

5.7 No Material Adverse Change in Financial Statements. All consolidated and consolidating financial statements related to Loan Parties and any Subsidiary that are delivered by Loan Parties to Bank or otherwise submitted to Bank fairly present in all material respects Loan Parties’ financial condition as of the date thereof and Loan Parties’ results of operations for the period then ended. There has not been a material adverse change in the consolidated or in the consolidating financial condition of any Loan Party since the date of the most recent of such financial statements submitted to Bank.

5.8 Solvency, Payment of Debts. Each Loan Party is able to pay its debts (including trade debts) as they mature; the fair saleable value of each Loan Party’s assets (including goodwill minus disposition costs)exceeds the fair value of its liabilities; and no Loan Party is left with unreasonably small capital after the transactions contemplated by this Agreement.

5.9 Compliance with Laws and Regulations. Each Loan Party and each Subsidiary have met the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. No event has occurred resulting from any Loan Party’s failure to comply with ERISA that is reasonably likely to result in such Loan Party incurring any liability that could reasonably be expected to have a Material Adverse Effect. No Loan Party is an “investment company” or a company “controlled” by an “investment company” within the meaning of the Investment Company Act of 1940. No Loan Party is engaged principally, or as one of its important activities, in the business of extending credit for the purpose of purchasing or carrying margin stock (within the meaning of Regulations T and U of the Board of Governors of the Federal Reserve System). No Loan


Party has violated any statutes, laws, ordinances or rules applicable to it, including without limitation Environmental Laws, the violation of which would reasonably be expected to have a Material Adverse Effect. Each Loan Party and each Subsidiary have filed or caused to be filed all tax returns required to be filed and have paid, or have made adequate provision for the payment of, all taxes reflected therein, except those being contested in good faith with adequate reserves under GAAP or where the failure to file such returns or pay such taxes would not reasonably be expected to have a Material Adverse Effect.

5.10 Subsidiaries. No Loan Party owns any Capital Stock of any Person, except for the Capital Stock of another Loan Party and for Permitted Investments.

5.11 Government Consents. Each Loan Party and each Subsidiary have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to all governmental authorities that are necessary for the continued operation of such Loan Party’s or Subsidiary’s business as currently conducted, except where the failure to do so would not reasonably be expected to cause a Material Adverse Effect.

5.12 Inbound Licenses. Except as disclosed on the Schedule, no Loan Party is a party to, nor is bound by, any material license or other agreement important for the conduct of such Loan Party’s business that prohibits or otherwise restricts such Loan Party from granting a security interest in such Loan Party’s interest in such license or agreement or any other property important for the conduct of such Loan Party’s business, other than this Agreement or the other Loan Documents.

5.13 Shares. As of the Closing Date, the Shares of the Canadian Subsidiary are uncertificated. Each Loan Party has full power and authority to create a first lien on the Shares, and no disability or contractual obligation exists that would prohibit such Loan Party from pledging the Shares pursuant to this Agreement. To each Loan Party’s knowledge, there are no subscriptions, warrants, rights of first refusal or other restrictions on transfer relative to, or options exercisable with respect, to the Shares. The Shares have been and will remain duly authorized and validly issued and are fully paid and non-assessable. To each Loan Party’s knowledge, the Shares are not the subject of any present or threatened suit, action, arbitration, administrative or other proceeding, and such Loan Party knows of no reasonable grounds for the institution of any such proceedings. No interest in any limited liability company or limited partnership controlled by a Loan Party is represented by a certificate unless (a) the limited liability company agreement or limited partnership agreement expressly provides that such interest shall be a “Security” within the meaning of Article8 of the Code, and (b) such certificate has been delivered to Bank. With respect to each limited liability company or limited partnership controlled by a Loan Party whose interests are uncertificated, such limited liability company or limited partnership has not elected, whether in its limited liability company agreement or limited partnership agreement or otherwise, to have such interests be treated as a “Security” within the meaning of Article 8 of the Code.

5.14 Full Disclosure. No representation, warranty or other statement made by any Loan Party in any report, certificate, or written statement furnished or submitted to Bank taken together with all such reports, certificates, and written statements furnished or submitted to Bank contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in such reports, certificates, or statements not misleading in light of the circumstances in which they were made, it being recognized by Bank that the projections and forecasts provided by a Loan Party in good faith and based upon reasonable assumptions are not to be viewed as facts and that actual results during the period or periods covered by any such projections and forecasts may materially differ from the projected or forecasted results.


6.
AFFIRMATIVE COVENANTS.

Each Loan Party covenants that, until payment in full of all outstanding Obligations (other than inchoate indemnity obligations and Ancillary Services that have been secured to Bank’s satisfaction pursuant to Section 2.1(b)(iv)), and for so long as Bank may have any commitment to make a Credit Extension hereunder, Loan Parties shall do all of the following:

6.1 Good Standing and Government Compliance. Each Loan Party shall maintain its and each of its Subsidiaries’ corporate existence and good standing in their respective states of formation, shall maintain qualification and good standing in each other jurisdiction in which the failure to so qualify would reasonably be expected to have a Material Adverse Effect, and shall furnish to Bank the organizational identification number issued to such Loan Party by the authorities of the state in which such Loan Party is organized, if applicable. Each Loan Party shall meet, and shall cause each Subsidiary to meet, the minimum funding requirements of ERISA with respect to any employee benefit plans subject to ERISA. Each Loan Party shall comply, and shall cause each Subsidiary to comply, with all statutes, laws, ordinances and government rules and regulations to which it is subject, including without limitation all Environmental Laws, and shall maintain, and shall cause each of its Subsidiaries to maintain, in force all licenses, approvals and agreements, the loss of which or failure to comply with which would reasonably be expected to have a Material Adverse Effect.

6.2 Financial Statements, Reports, Certificates; Collateral Audits.

(a) Loan Parties shall deliver to Bank: (i) within 45 days after the end of each calendar quarter, a company-prepared consolidated balance sheet, income statement, and statement of cash flows covering Turnstone Group’s operations during such period, prepared in accordance with GAAP, consistently applied (subject to year-end audit adjustments and the absence of footnotes), in a form reasonably acceptable to Bank and certified by a Responsible Officer; (ii) within 180 days after the end of each of Parent’s fiscal years, audited (or such other level of review as Parent’s board of directors requires) consolidated financial statements of Turnstone Group prepared in accordance with GAAP, consistently applied, together with, if audited, an unqualified opinion (other than a going concern qualification based solely on Borrower having negative profits or a determination that Borrower has fewer than 12 months’ liquidity) on such financial statements from an independent certified public accounting firm of nationally recognized standing or other accounting firm reasonably acceptable to Bank; (iii) an annual budget (which shall include a balance sheet, income statement, and statement of cash flows for each calendar month),approved by Parent’s board of directors, for each of Parent’s fiscal years not later than 45 days after the beginning of such fiscal year; (iv) if applicable, copies of all statements, reports and notices sent or made available generally by Parent to its shareholders or to any holders of Subordinated Debt and all reports on Forms 10-K and 10-Q filed with the Securities and Exchange Commission; (v) promptly upon receipt of notice thereof, a report of any legal actions pending or threatened against any Loan Party or any Subsidiary that could reasonably be expected to result in damages or costs to any Loan Party or any Subsidiary of $500,000 or more; (vi) promptly upon receipt, each management letter prepared by an independent certified public accounting firm regarding Parent’s management control systems; (vii) such budgets, sales projections, operating plans or other financial information as Bank may reasonably request from time to time; and (viii) promptly upon Bank’s request, and otherwise as Loan Parties may determine, informal updates on any material developments with Loan Parties.

Loan Parties may deliver to Bank on an electronic basis any certificates, reports, requests, or information required pursuant to this Section 6.2, and Bank shall be entitled to rely on the information contained in the electronic files, provided that Bank in good faith believes that the files were delivered by, or on behalf of, a Responsible Officer. Loan Parties shall include a submission date on any certificates, statements, and reports to be delivered electronically.

Any submission by Loan Parties of a Compliance Certificate or other financial statement pursuant to this Section 6.2or otherwise submitted to Bank shall be deemed to be a representation by each Loan Party that (v) as of the date of such Compliance Certificate, financial statement, or request, the information and calculations set forth therein are true, accurate and correct; (w) as of the end of the compliance period set forth in such submission, Loan Parties are in complete compliance with all required covenants except as noted in such Compliance Certificate or financial statement, as applicable; (x) as of the date of such submission, no Event of Default has occurred and is continuing; and (y) all representations and warranties, other than any representations or warranties that are made as of a specific date in Article 5, remain true and correct in all material respects as of the date of such submission except as noted in such Compliance Certificate, financial statement, or request, as applicable.

have a security interest in it that might otherwise be restricted by the terms of the applicable license or agreement, whether now existing or entered into in the future, provided, however, that the failure to obtain any such consent or waiver shall not constitute a default under this Agreement.

6.9 Creation/Acquisition of Subsidiaries. In the event that a Loan Party or any Subsidiary of a Loan Party creates or acquires any Subsidiary, such Loan Party or Subsidiary shall promptly notify Bank of such creation or acquisition, and such Loan Party or Subsidiary shall take all actions reasonably requested by Bank to achieve any of the following with respect to such “New Subsidiary” (defined as a Subsidiary formed after the date hereof during the term of this Agreement): (a) to cause such New Subsidiary to become either(i) a Guarantor hereunder, if such New Subsidiary is organized under the laws of the United States, or (ii) a secured guarantor with respect to the Obligations, if such New Subsidiary is not organized under the laws of the United States; and (b) to grant and pledge to Bank a perfected security interest in 100% of the Capital Stock held by such Loan Party or Subsidiary of any such New Subsidiary.

Loan Parties agree to take all actions reasonably requested by Bank to accomplish such actions.

9.
BANK’S RIGHTS AND REMEDIES.

9.1 Rights and Remedies. Upon the occurrence and during the continuance of an Event of Default, Bank may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by each Loan Party:

(a)`declare all Obligations, whether evidenced by this Agreement, by any of the other Loan Documents, or otherwise, immediately due and payable (provided that, upon the occurrence of an Event of Default described in Section 8.5 (insolvency), all Obligations shall become immediately due and payable without any action by Bank);

(b) demand that Borrower (i) deposit cash with Bank in an amount equal to the amount of any Letters of Credit remaining undrawn as collateral security for the repayment of any future drawings under such Letters of Credit, and (ii) pay in advance all Letter of Credit fees scheduled to be paid or payable over the remaining term of the Letters of Credit, and Borrower shall promptly deposit and pay such amounts;

(c) cease advancing money or extending credit to or for the benefit of any Loan Party under this Agreement or under any other agreement between a Loan Party and Bank;

(d) settle or adjust disputes and claims directly with account debtors for amounts, upon terms and in whatever order that Bank reasonably considers advisable;

(e) make such payments and do such acts as Bank considers necessary or reasonable to protect its security interest in the Collateral. Each Loan Party agrees to assemble the Collateral if Bank so requires and to make the Collateral available to Bank as Bank may designate. Each Loan Party authorizes Bank to enter the premises where the Collateral is located, to take and maintain possession of the Collateral, or any part of it, and to pay, purchase, contest, or compromise any encumbrance, charge, or lien which in Bank’s determination appears to be prior or superior to its security interest and to pay all expenses incurred in connection therewith.

With respect to any Loan Party’s owned premises, such Loan Party hereby grants Bank a license to enter into possession of such premises and to occupy the same, without charge, in order to exercise any of Bank’s rights or remedies provided herein, at law, in equity, or otherwise;

(f) place a “hold” on any account maintained with Bank, decline to honor presentments (including but not limited to checks, wires, and ACH drafts) against any account at Bank, and/or deliver a notice of exclusive control, an entitlement order, or other directions or instructions pursuant to any control agreement or similar agreements providing control of any Collateral;

(g) set off and apply to the Obligations any and all (i) balances and deposits of any Loan Party held by Bank, and (ii) indebtedness at any time owing to or for the credit or the account of any Loan Party held by Bank;

(h) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein)the Collateral. Bank is hereby granted a license or other right, solely pursuant to the provisions of this Section 9.1, to use, without charge, any Loan Party’s labels, Patents, Copyrights, rights of use of any name, trade secrets, trade names, Trademarks, service marks, and advertising matter, or any property of a similar nature, as it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Bank’s exercise of its rights under this Section 9.1, any Loan Party’s rights under all licenses and all franchise agreements shall inure to Bank’s benefit;

(i) sell the Collateral at either a public or private sale, or both, by way of one or more contracts or transactions, for cash or on terms, in such manner and at such places (including any


Loan Party’s premises) as Bank determines is commercially reasonable, and apply any proceeds to the Obligations in whatever manner or order Bank deems appropriate. Bank may sell the Collateral without giving any warranties as to the Collateral. Bank may specifically disclaim any warranties of title or the like. This procedure will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral. If Bank sells any of the Collateral upon credit, Loan Parties will be credited only with payments actually made by the purchaser, received by Bank, and applied to the indebtedness of the purchaser. If the purchaser fails to pay for the Collateral, Bank may resell the Collateral and Loan Parties shall be credited with the proceeds of the sale;

(j) credit bid and purchase Collateral at any public sale;

(k) apply for the appointment of a receiver, trustee, liquidator or conservator of the Collateral, without notice and without regard to the adequacy of the security for the Obligations and without regard to the solvency of any Loan Party, any guarantor or any other Person liable for any of the Obligations; and

(l) any deficiency that exists after disposition of the Collateral as provided above will be paid immediately by Loan Parties.

Bank may comply with any applicable state or federal law requirements in connection with a disposition of the Collateral, and compliance will not be considered adversely to affect the commercial reasonableness of any sale of the Collateral.

9.2 Power of Attorney. Effective only upon the occurrence and during the continuance of an Event of Default, each Loan Party hereby irrevocably appoints Bank (and any of Bank’s designated officers or employees) as such Loan Party’s true and lawful attorney to: (a) send requests for verification of Accounts or notify account debtors of Bank’s security interest in the Accounts; (b) endorse such Loan Party’s name on any checks or other forms of payment or security that may come into Bank’s possession; (c) sign such Loan Party’s name on any invoice or bill of lading relating to any Account, drafts against account debtors, schedules and assignments of Accounts, verifications of Accounts, and notices to account debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims under and decisions with respect to such Loan Party’s policies of insurance; (f) settle and adjust disputes and claims respecting Accounts directly with account debtors, for amounts and upon terms which Bank determines to be reasonable; and (g) file, in its sole discretion, one or more financing or continuation statements and amendments thereto, relative to any of the Collateral; provided that Bank may exercise such power of attorney to sign the name of a Loan Party on any of the documents described in clause (g)above regardless of whether an Event of Default has occurred. The appointment of Bank as such Loan Party’s attorney in fact, and each and every one of Bank’s rights and powers, being coupled with an interest, is irrevocable until all of the Obligations (other than inchoate indemnity obligations and Ancillary Services that have been secured to Bank’s satisfaction pursuant to Section 2.1(b)(iv)) have been fully repaid and performed and Bank’s obligation to provide advances hereunder is terminated.

9.3 Accounts Collection. At any time after the occurrence and during the continuation of an Event of Default, Bank may notify any Person owing funds to any Loan Party of Bank’s security interest in such funds and verify the amount of such Account. Each Loan Party shall collect all amounts owing to such Loan Party for Bank, receive in trust all payments as Bank’s trustee and immediately deliver such payments to Bank in their original form as received from the account debtor, with proper endorsements for deposit.

9.4 Bank Expenses. If any Loan Party fails to pay any amounts or furnish any required proof of payment due to third persons or entities, as required under the terms of this Agreement, then Bank may do any or all of the following after reasonable notice to such Loan Party: (a) make payment of


the same or any part thereof; (b) set up such reserves under the Non- Formula Revolving Line as Bank deems necessary to protect Bank from the exposure created by such failure; or (c) obtain and maintain insurance policies of the type discussed in Section 6.5 of this Agreement, and take any action with respect to such policies as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be immediately due and payable, shall bear interest at the then applicable rate herein above provided, and shall be secured by the Collateral. Any payments made by Bank shall not constitute an agreement by Bank to make similar payments in the future or a waiver by Bank of any Event of Default under this Agreement.

9.5 Bank’s Liability for Collateral. Bank has no obligation to clean up or otherwise prepare the Collateral for sale. All risk of loss, damage or destruction of the Collateral shall be borne by Loan Parties.

9.6 No Obligation to Pursue Others. Bank has no obligation to attempt to satisfy the Obligations by collecting them from any other Person liable for them, and Bank may release, modify, or waive any collateral provided by any other Person to secure any of the Obligations, all without affecting Bank’s rights against any Loan Party. Each Loan Party waives any right it may have to require Bank to pursue any other Person for any of the Obligations.

9.7 Remedies Cumulative. Bank’s rights and remedies under this Agreement, the Loan Documents, and all other agreements shall be cumulative. Bank shall have all other rights and remedies not inconsistent herewith as provided under the Code, by law, or in equity. No exercise by Bank of one right or remedy shall be deemed an election, and no waiver by Bank of any Event of Default on a Loan Party’s part shall be deemed a continuing waiver. No delay by Bank shall constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be effective unless made in a written document signed on behalf of Bank and then shall be effective only in the specific instance and for the specific purpose for which it was given. Each Loan Party expressly agrees that this Section 9.7 may not be waived or modified by Bank by course of performance, conduct, estoppel, or otherwise.

9.8 Demand; Protest. Except as otherwise provided in this Agreement, each Loan Party waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, and any other notices relating to the Obligations.

13.3 The obligations hereunder are joint and several, and the obligations hereunder are independent of the obligations of Borrower and any other Person or entity, and a separate action or actions may be brought and prosecuted against Guarantors whether action is brought against Borrower or whether Borrower be joined in any such action or actions.

Guarantors waive all presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor and notices of acceptance of this guaranty and of the existence, creation or incurring of new or additional indebtedness.

proceeding some or all of any indebtedness or obligations under the Loan Documents are terminated or rejected or any obligation of Borrower is modified or abrogated, or if Borrower’s obligations are otherwise avoided for any reason, Guarantors agree that Guarantors’ liability hereunder shall not thereby be affected or modified and such liability shall continue in full force and effect as if no such action or proceeding had occurred. This guaranty shall continue to be effective or be reinstated, as the case may be, if any payment must be returned by Bank upon the insolvency, bankruptcy or reorganization of Borrower, a Guarantor or otherwise, as though such payment had not been made.

13.7 Any indebtedness of Borrower now or hereafter held by Guarantors is hereby subordinated to any indebtedness of Borrower to Bank; and such indebtedness of Borrower to Guarantors shall be collected, enforced and received by Guarantors as trustees for Bank and be paid over to Bank on account of the indebtedness of Borrower to Bank but without reducing or affecting in any manner the liability of Guarantors under the other provisions of this guaranty.

13.8 Guarantors agree to pay all Bank Expenses which may be incurred by Bank in the enforcement of this guaranty. No terms or provisions of this guaranty may be changed, waived, revoked or amended except in compliance with Section 12.5. Should any provision of this guaranty be determined by a court of competent jurisdiction to be unenforceable, all of the other provisions shall remain effective. This guaranty, together with any agreements (including without limitation any security agreements or any pledge agreements) executed in connection with this guaranty, embodies the entire agreement among the parties hereto with respect to the matters set forth herein and supersedes all prior agreements among the parties with respect to the matters set forth herein. No course of prior dealing among the parties, no usage of trade, and no parol or extrinsic evidence of any nature shall be used to supplement, modify or vary any of the terms hereof. There are no conditions to the full effectiveness of this guaranty. Bank may assign this guaranty without in any way affecting Guarantors’ liability under it. This guaranty shall inure to the benefit of Bank and its successors and assigns. This guaranty is in addition to the guarantees of any other guarantors and any and all other guarantees of Borrower’s indebtedness or liabilities to Bank.

13.9 All payments made by Guarantors hereunder will be made free and clear of, and without deduction or withholding for, any present or future taxes (but excluding any tax imposed on or measured by the net income or profits of Bank pursuant to the laws of the jurisdiction in which it is organized or the jurisdiction in which the principal office or applicable lending office of Bank is located or any subdivision thereof or therein) and all interest, penalties or similar liabilities with respect thereto. If any taxes are so levied or imposed, Guarantors agree to pay the full amount of such taxes, and such additional amounts as may be necessary so that every payment of all amounts due under this guaranty, after withholding or deduction for or on account of any taxes, will not be less than the amount provided for herein and in this Agreement.
