Part 401 et al. (“Bayh-Dole Act”); and (b) MAYO’s and its Affiliates’ reserved, irrevocable right to practice and have practiced the Patent Rights and Materials for non-commercial purposes in connection with the educational, research and clinical programs of MAYO, Mayo Clinic Platform, MAYO’s Affiliates, including MAYO’s reference laboratory and Mayo Collaborative Services, LLC, and the Mayo Clinic Care Network. SORRENTO agrees to comply with the provisions of the Bayh-Dole Act, including promptly providing to MAYO with information requested to enable MAYO to meet its compliance requirements and substantially manufacturing Licensed Product in the U.S.

2.03NO OTHER RIGHTS GRANTED. This Agreement does not grant any right, title or interest outside the Field or Territory or any right, title or interest in or to any tangible or intangible property right of MAYO or its Affiliates, including but not limited to any patent rights, know-how or material or any improvements thereon, which is not expressly stated herein, including pursuant to Sections 2.01 (Grant) and 2.04(a) (Additional Rights, Sponsored Research). All such other rights, titles and interests are expressly reserved by MAYO and SORRENTO agrees that in no event will this Agreement (i) exhaust any MAYO patent rights, or (ii) be construed as a sale, an assignment or an implied license by MAYO or its Affiliates to SORRENTO of any tangible or intangible property rights.

a)Sponsored Research. Notwithstanding anything to the contrary contained herein (including Section 2.03), the Parties agree that the licenses and rights under this Agreement shall cover all improvements to the Licensed IP and any other intellectual property (including patent rights, know-how, data, materials and any improvements thereon) developed in connection with or otherwise arising from any sponsored research funded by SORRENTO or any of its Affiliates, pursuant to any separate sponsored research agreement(s) as contemplated in Section 3.07 hereof.

b)Other Research. Subject to any third party rights and solely during the Royalty Term, MAYO shall make best efforts to make SORRENTO aware of any intellectual property that is targeted nanoparticle therapeutics and/or antibody drug conjugates that are developed without funding by SORRENTO and not by Mayo Investigators funded by SORRENTO, to allow SORRENTO a reasonable opportunity to negotiate a license to such intellectual property on commercially reasonable terms and, upon request by SORRENTO, MAYO shall (or shall cause its Affiliate(s), as applicable to) negotiate in good faith with SORRENTO to effect such license(s).

c)Other IP Rights. MAYO agrees not to assert against SORRENTO or its Affiliates any other intellectual property rights owned and controlled by MAYO as of the Effective Date based on SORRENTO’s or its Affiliates’ use of the Materials solely in the form provided by MAYO to SORRENTO listed in Exhibit A as of the Effective Date, if and to the extent such Materials infringes or misappropriates such other intellectual property rights of MAYO. For the avoidance of doubt, such forbearance is not transferrable without Mayo’s prior written consent.

2.05SUBLICENSES. Any sublicense by SORRENTO, other than to an Affiliate shall be to a Sublicensee that agrees in writing to be bound by substantially similar terms and conditions as SORRENTO herein, as applicable (for clarity, excluding financial terms and conditions), or such sublicense shall be null and void. Sublicenses granted hereunder shall not be assignable without the prior written approval of MAYO consistent with the terms and conditions of Section 11.11 hereof; provided, that any such assignation assignment in violation of such terms and conditions shall be null and void. SORRENTO will provide MAYO with an un-redacted copy of each sublicense agreement (including those through multiple tiers) promptly after execution, which shall be deemed and treated as the Confidential Information of SORRENTO. As between the Parties, SORRENTO shall be responsible for the performance of all Affiliates and Sublicensees as if such performance were carried out by SORRENTO itself, including the payment of any royalties or other payments provided for and due to MAYO hereunder triggered by such Sublicense, regardless of whether the terms of any sublicense require that Sublicensee pay such amounts (such as in a fully paid-up license) to SORRENTO or that such amounts be paid by the Sublicensee directly to MAYO. Each sublicense agreement with a Sublicensee shall name MAYO as a third party beneficiary and, unless MAYO has provided written consent, all rights of Sublicensees shall terminate when SORRENTO’s rights terminate. For the avoidance of doubt, the granting by SORRENTO of any fully-paid up or royalty-free sublicenses will not alleviate the obligation of SORRENTO to pay the Earned Royalty based on Net Sales of Royalty-Bearing Products made by such applicable Sublicensee.

a)In consideration for the rights granted herein, SORRENTO shall, within six (6) trading days of the Effective Date, pay to MAYO NINE MILLION THREE HUNDRED THOUSAND DOLLARS (US $9,300,000) (the “Upfront Payment Amount”), which payment shall be comprised (A) solely of shares of restricted SORRENTO common stock (the “Shares”) (with the number of Shares calculated in accordance with the next sentence), or (B) any combination of cash paid in immediately available funds via wire transfer to an account designated by MAYO in writing and Shares (with the number of Shares calculated in accordance with the next sentence), in any case as determined by SORRENTO in its sole and absolute discretion; provided that the portion of the Upfront Payment Amount comprised of cash shall not exceed 25% of the Upfront Payment Amount. The Shares shall be issued to MAYO in the name of Mayo Clinic and the number of Shares issuable shall be equal to the quotient obtained by dividing (i) the dollar amount of the Upfront Payment Amount to be paid in Shares by (ii) the weighted average closing price of SORRENTO’s common stock, as reported on The Nasdaq Stock Market LLC, for the 11 consecutive trading days beginning on the 5th trading day prior to the date of this Agreement; provided that in no event shall the value in clause (ii) be less than FOUR DOLLARS AND NINETY SIX CENTS (US $4.96) nor greater than SEVEN DOLLARS AND FORTY FOUR CENTS (US $7.44). In addition, in no event shall the number of Shares equal more than FIFTY ONE MILLION EIGHT HUNDRED AND ONE THOUNSAND ONE HUNDRED AND SIXTY TWO (51,801,162) shares of SORRENTO’s common stock.

3.04ROYALTY STACKING. If SORRENTO is a party to a license agreement with any third party under which SORRENTO obtains a license for technology reasonable required for the manufacture, use, sale, import, export, or other Exploitation of a Royalty-Bearing Product then SORRENTO may reduce the Earned Royalties due to MAYO on such Royalty-Bearing Product

(on a product-by-product basis) by [...***...] percent ([...***...]%) of the royalties that are payable to such third party; provided, however, that in no event will the Earned Royalties be reduced to less than [...***...] percent ([...***...]%) of the Earned Royalties that would otherwise be payable under Section 3.03 (Earned Royalties). For the avoidance of doubt, the Earned Royalties otherwise due may not be reduced to more than [...***...] percent ([...***...]%) regardless of the number of additional licenses to which SORRENTO is a party.

Such sponsored research activities may include basic research projects, as well as toxicology, GMP manufacturing or additional Phase I or Phase II clinical trials of the Licensed IP. The Parties shall mutually agree upon any additional research funding for work to be done at MAYO in subsequent years. Any sponsored research shall be outlined and agreed upon in a separate research agreement between MAYO and SORRENTO.

3.08PRIORITY REVIEW. In the event that SORRENTO receives an FDA priority review voucher or similar transferrable asset based on a submission relating to a Licensed Product and elects to sell or otherwise transfer such asset to a third party, SORRENTO will share [...***...] ([...***...]%) of any consideration in any form received by SORRENTO in exchange.

b)SORRENTO shall notify MAYO: (i) when the Resale Registration Statement, or any amendment thereto has been filed with the SEC and when the Resale Registration Statement or any post-effective amendment thereto has become effective; (ii) of any request by the SEC for amendments or supplements to the Resale Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of the Resale Registration Statement or the initiation of any proceedings for that purpose and of any other action, event or failure to act that would cause the Resale Registration Statement not to remain effective; and (iv) of the receipt by SORRENTO of any notification with respect to the suspension of the qualification or exemption from qualification of any Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose.

c)As promptly as practicable after becoming aware of such event, SORRENTO shall notify MAYO of the happening of any event (a “Suspension Event”), of which SORRENTO has knowledge, as a result of which the prospectus included in the Resale Registration Statement as then in effect, includes an untrue statement of a material fact or omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and use its best efforts promptly to prepare a supplement or amendment to the Resale Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to MAYO as MAYO may reasonably

request; provided, however, that, for not more than 30 consecutive trading days (or a total of not more than 90 trading days in any 12 month period), SORRENTO may delay, to the extent permitted by and in a manner not in violation of applicable securities laws, the disclosure of material non-public information concerning SORRENTO (as well as prospectus or Resale Registration Statement updating), the disclosure of which at the time is not, in the good faith opinion of SORRENTO, in the best interests of SORRENTO; provided, further, that, if the Resale Registration Statement was not filed on Form S-3, such number of days shall not include the 15 calendar days following the filing of any Current Report on Form 8-K, Quarterly Report on Form 10-Q or Annual Report on Form 10-K, or other comparable form, for purposes of filing a post-effective amendment to the Resale Registration Statement.

d)Upon a Suspension Event, SORRENTO shall give written notice (a “Suspension Notice”) to MAYO to suspend sales of the affected Registrable Securities, and such notice shall state that such suspension shall continue only for so long as the Suspension Event or its effect is continuing and SORRENTO is pursuing with reasonable diligence the completion of the matter giving rise to the Suspension Event or otherwise taking all reasonable steps to terminate suspension of the effectiveness or use of the Resale Registration Statement provided, however, that the Suspension shall not be for more than 30 consecutive trading days (or a total of not more than 90 trading days in any 12 month period). In no event shall SORRENTO, without the prior written consent of MAYO, disclose to MAYO any of the facts or circumstances giving rise to the Suspension Event. MAYO shall not effect any sales of the Registrable Securities pursuant to such Resale Registration Statement (or such filings), at any time after it has received a Suspension Notice and prior to receipt of an End of Suspension Notice. MAYO may resume effecting sales of the Registrable Securities under the Resale Registration Statement (or such filings), following further notice to such effect (an “End of Suspension Notice”) from SORRENTO. This End of Suspension Notice shall be given by SORRENTO to MAYO in the manner described above promptly following the conclusion of any Suspension Event and its effect. For the avoidance of doubt, a Suspension Notice shall not affect or otherwise limit sales of affected Registrable Securities under Rule 144 or otherwise outside of the Resale Registration Statement.

e)Notwithstanding any provision herein to the contrary, if SORRENTO gives a Suspension Notice pursuant to this Section 3.14with respect to the Resale Registration Statement, SORRENTO shall extend the period during which the Resale Registration Statement shall be maintained effective under this Agreement by the number of days during the period from the date of the giving of the Suspension Notice to and including the date when MAYO shall have received the End of Suspension Notice and copies of the supplemented or amended prospectus necessary to resume sales; provided however, such period of time shall not be extended beyond the date that the Registrable Securities can be sold under Rule 144 without restriction.

f)SORRENTO shall bear all Registration Expenses incurred in connection with the registration of the Registrable Securities pursuant to this Agreement. “Registration Expenses” shall mean any and all expenses incident to the performance of or compliance with this Agreement, including without limitation: (i) all registration and filing fees; (ii) all fees and expenses associated with a required listing of the Registrable Securities on any securities exchange; (iii) fees and expenses with respect to filings required to be made with an exchange or any securities industry self-regulatory body; (iv) fees and expenses of compliance with securities or “blue sky” laws (including reasonable fees and disbursements of counsel for the underwriters

or holders of securities in connection with blue sky qualifications of the securities and determination of their eligibility for investment under the laws of such jurisdictions); (v) printing, messenger, telephone and delivery expenses of SORRENTO; (vi) fees and disbursements of counsel for SORRENTO and customary fees and expenses for independent certified public accountants retained by SORRENTO (including the expenses of any comfort letters, or costs associated with the delivery by independent certified public accountants of a comfort letter or comfort letters, if such comfort letter or comfort letters is required by the managing underwriter); (vii) securities acts liability insurance, if SORRENTO so desires; (viii) all internal expenses of SORRENTO (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties); (ix) the expense of any annual audit; and (x) the fees and expenses of any Person, including special experts, retained by SORRENTO; provided, however that “Registration Expenses” shall not include underwriting fees, discounts or commissions attributable to the sale of the Registrable Securities or any legal fees and expenses of counsel to MAYO.

g)Notwithstanding anything to the contrary contained in this Agreement, SORRENTO shall not be required to include Registrable Securities in the Resale Registration Statement unless MAYO, following reasonable advance written request by SORRENTO, furnishes to SORRENTO, at least 10 business days prior to the scheduled filing date of the Resale Registration Statement, an executed stockholder questionnaire in the form attached hereto as Exhibit C.

a)In the event of the offer and sale of the Registrable Securities held by MAYO under the Securities Act, SORRENTO agrees to indemnify and hold harmless MAYO and its directors, officers, employees, affiliates and agents and each Person who controls MAYO within the meaning of the Securities Act or the Exchange Act of 1934, as amended (the “Exchange Act”), (collectively, the “MAYO Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or any actions in respect thereof to which each MAYO Indemnified Party may become subject under the Securities Act or the Exchange Act, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Resale Registration Statement or in any amendment thereof, in each case at the time such became effective under the Securities Act, or in the preliminary prospectus or other information that is deemed, under Rule 159 promulgated under the Securities Act to have been conveyed to purchasers of securities at the time of sale of such securities (“Disclosure Package”), in the prospectus or in any amendment thereof or supplement thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Disclosure Package or any prospectus, in the light of the circumstances under which they were made) not misleading, and shall reimburse, as incurred, the MAYO Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that SORRENTO shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or omission made in the Resale Registration Statement, the Disclosure Package, any prospectus or in any amendment thereof or supplement thereto in reliance upon and in conformity with written information pertaining to MAYO and furnished to SORRENTO by or on behalf of such MAYO

Indemnified Party specifically for inclusion therein; provided further, however, that SORRENTO shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Disclosure Package, where (A) such statement or omission had been eliminated or remedied in any subsequently filed amended prospectus or prospectus supplement (the Disclosure Package, together with such updated documents, the “Updated Disclosure Package”), the filing of which MAYO had been notified in accordance with the terms of this Agreement, (B) such Updated Disclosure Package was available at the time MAYO sold Registrable Securities under the Resale Registration Statement, (C) such Updated Disclosure Package was not furnished by MAYO to the Person asserting the loss, liability, claim, damage or liability, or an underwriter involved in the distribution of such Registrable Securities, at or prior to the time such furnishing is required by the Securities Act, and (D) the Updated Disclosure Package would have cured the defect giving rise to such loss, liability, claim, damage or action; and provided further, however, that this indemnity agreement will be in addition to any liability that SORRENTO may otherwise have to such MAYO Indemnified Party. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of any MAYO Indemnified Parties and shall survive the transfer of the Registrable Securities by MAYO.

b)As a condition to including any Registrable Securities to be offered by MAYO in any registration statement filed pursuant to this Agreement, MAYO agrees to indemnify and hold harmless SORRENTO, each of its directors, each of its officers who signs the Resale Registration Statement, as well as any officers, employees, affiliates and agents of SORRENTO, and each Person, if any, who controls SORRENTO within the meaning of the Securities Act or the Exchange Act (a “SORRENTO Indemnified Party”) from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which a SORRENTO Indemnified Party may become subject under the Securities Act or the Exchange Act, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Resale Registration Statement or in any amendment thereof, in each case at the time such became effective under the Securities Act, or in any Disclosure Package, prospectus or in any amendment thereof or supplement thereto, or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of the Disclosure Package or any prospectus, in the light of the circumstances under which they were made) not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to MAYO and furnished to SORRENTO by or on behalf of MAYO specifically for inclusion therein; and, subject to the limitation immediately preceding this clause, shall reimburse, as incurred, the SORRENTO Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of MAYO, or any such director, officer, employees, affiliates and agents and shall survive the transfer of such Registrable Securities by MAYO, and MAYO shall reimburse SORRENTO, and each such director, officer, employees, affiliates and agents for any legal or other expenses reasonably incurred by them in connection with investigating, defending, or settling and such loss, claim, damage, liability, action, or proceeding; provided, however, that the indemnity amount contained in this Section 3.15(b) shall in no event exceed the gross proceeds from the offering received by MAYO. Such indemnity shall remain in full

force and effect, regardless of any investigation made by or on behalf of SORRENTO or any such director, officer, employees, affiliates and agents and shall survive the transfer by MAYO of such Registrable Securities.

c)Promptly after receipt by a MAYO Indemnified Party or a Company Indemnified Party (each, an “Indemnified Party”) of notice of the commencement of any action or proceeding (including a governmental investigation), such Indemnified Party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 3.15, notify the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve the indemnifying party from liability under Sections 3.15 (a) or 3.15 (b) unless and to the extent it did not otherwise learn of such action and the indemnifying party has been materially prejudiced by such failure. In case any such action is brought against any Indemnified Party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party (who shall not, except with the consent of the Indemnified Party, be counsel to the indemnifying party), and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof the indemnifying party will not be liable to such Indemnified Party under this Section 3.15 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however, if such Indemnified Party shall have been advised by counsel that there are one or more defenses available to it that are in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the Indemnified Party), the reasonable fees and expenses of such Indemnified Party’s counsel shall be borne by the indemnifying party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for any Indemnified Party in connection with any one action or separate but substantially similar or related actions arising in the same jurisdiction out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the Indemnified Party (not to be unreasonably withheld or delayed), effect any settlement of any pending or threatened action in respect of which any Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party unless such settlement (i) includes an unconditional release of such Indemnified Party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Party. If the indemnification provided for in this Section 3.15 is unavailable or insufficient to hold harmless an Indemnified Party under Sections 3.15(a) or 3.15(b), then each indemnifying party shall contribute to the amount paid or payable by such Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in Sections 3.15(a) or 3.15(b) in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and the Indemnified Party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by SORRENTO on the one hand or MAYO or MAYO Indemnified Party, as the case may be, on the other, and the parties’ relative intent, knowledge,

access to information and opportunity to correct or prevent such statement or omission. The amount paid by an Indemnified Party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this Section 3.15(c) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any action or claim that is the subject of this Section 3.15(c). The parties agree that it would not be just and equitable if contributions were determined by pro rata allocation (even if MAYO was treated as one entity for such purpose) or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding any other provision of this Section 3.15(c), MAYO shall not be required to contribute any amount in excess of the amount by which the net proceeds received by MAYO from the sale of the Registrable Securities pursuant to the Resale Registration Statement exceeds the amount of damages that MAYO has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

d)The agreements contained in this Section 3.15 shall survive the sale of the Registrable Securities pursuant to the Resale Registration Statement, and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any Indemnified Party.

4.01REPORTS AND PAYMENT. SORRENTO will deliver to MAYO on or before the following dates: 1 February, 1 May, 1 August and 1 November, a written report setting forth a full accounting showing how any amounts due to MAYO for the preceding calendar quarter have been calculated as provided in this Agreement, including an accounting of total Net Sales with a reporting of any applicable foreign exchange rates, deductions, allowances, and charges and any payments due from Sublicensees. Each report will include product names, part numbers and quantity sold for each country in which the Licensed Product was sold. Furthermore, the report will include detailed information about Licensed Products sold to MAYO or MAYO Affiliates. If no Licensed Product transfers have occurred and no other amounts are due to MAYO, SORRENTO will submit a report so stating. Each such report will be accompanied by the payment of all amounts due for such reporting period. The first report and payment due each calendar year shall also be accompanied by a reporting of the prior year’s best net price for each Licensed Product, per Section 3.09.

4.02ACCOUNTING. SORRENTO will, and shall require its Affiliates and Sublicensees to keep, throughout the Term, keep complete, continuous, true and accurate books of accounts and records sufficient to support and verify the calculation of Net Sales, all royalties and any other amount believed due and payable to MAYO under this Agreement. Such books and records may be audited no more than once in any calendar year by an independent third party auditor reasonably acceptable to SORRENTO and MAYO solely for audit and verification of royalty statements and the other amounts owed to MAYO hereunder. The MAYO representative will treat as confidential all relevant matters and will be a person or firm reasonably acceptable to SORRENTO. In the event such audit reveals an underpayment by SORRENTO, SORRENTO will within thirty (30) days pay the royalty due in excess of the royalty actually paid. In the event the audit reveals an underpayment by SORRENTO of more than [...***...] percent

([...***...]%) of the amount due, SORRENTO will pay interest on the royalty due in excess of the royalty actually paid at the highest rate then permitted by law. In either event, SORRENTO will pay all of MAYO’s costs in conducting the audit.

5.01DEVELOPMENT PLAN. SORRENTO will make Commercially Reasonable Efforts to bring Licensed Products to market in the Field in the Territory. Within three months of the Effective Date and annually thereafter, SORRENTO will provide to MAYO a development plan, and the Parties shall discuss in good faith to mutually agree upon the Licensed Products being brought forth as well as target milestones that describes how SORRENTO intends to bring Licensed Products to market, which shall be attached hereto as Exhibit D, Development Plan, incorporated herein by reference.

5.02DILIGENCE REPORTS. SORRENTO will provide MAYO with annual reports within thirty (30) days of each anniversary of the Effective Date describing in detail: (a) as of that reporting period, all development and marketing activities for each Licensed Product and the names of all Sublicensees, including which of the Sublicensees are Affiliates; and (b) an updated development plan for the next annual period. MAYO shall have the right, no more than once annually, to reasonably audit SORRENTO’s and Sublicensees’ records relating to development of Licensed Products.

6.01CONTROL. SORRENTO will have the first right to prepare, file, prosecute, abandon, or otherwise handle the Patent Rights, using counsel of SORRENTO’s selection, with prior advice and comment from MAYO. SORRENTO shall pay all reasonable, documented unreimbursed costs and expenses associated with the filing, prosecution and maintenance of the Patent Rights, whether arising before or during the Term. [...***...]. In the event that SORRENTO decides not to (i) prosecute or maintain an application or patent within the Patent Rights; or (ii) pursue claims suggested by MAYO, SORRENTO shall inform MAYO of such decision at least thirty (30) days prior to the relevant deadline. Should MAYO then choose to (a) continue the prosecution or maintenance of an application or patent abandoned by SORRENTO; or (b) file a patent application pursuing claims not pursued by SORRENTO, MAYO shall pay the cost of such activity, and any license to the SORRENTO for such patent rights shall terminate. MAYO shall have sole control over the protection, defense, enforcement, maintenance, abandonment and other handling of the Know-How and Materials. MAYO will have no liability to SORRENTO for any act or omission in the preparation, filing, prosecution, maintenance, abandonment, or other handling of the Patent Rights and Know-How and Materials.

6.02ENFORCEMENT. The Parties shall promptly notify each other of any suspected infringement of any Patent Rights.

a)During the Term, SORRENTO shall, at its expense, have the first right to enforce any Patent Rights against such infringer. SORRENTO agrees to defend MAYO against any counterclaim brought against it in such action. MAYO shall reasonably cooperate with SORRENTO in such effort, at SORRENTO‘s expense, including being joined as a party to such

action, if deemed by a court with competent jurisdiction as a necessary party. SORRENTO shall reimburse MAYO for any reasonable costs incurred, including reasonable attorneys’ fees, as part of any action brought by SORRENTO.

b)SORRENTO shall have the right to enter into any settlement agreement, voluntary dismissal, consent judgment or other voluntary final disposition in any action regarding the Patent Rights, provided that SORRENTO will give MAYO a reasonable opportunity to review and comment on any such proposed settlement agreement, voluntary dismissal, consent judgment, or other voluntary final dismissal and SORRENTO will not enter into such proposed settlement agreement, voluntary dismissal, consent judgment, or other voluntary final dismissal if MAYO reasonably objects to the same (and in which case the Parties will promptly work together to identify a mutually acceptable resolution to such action). Any amounts received for punitive or exemplary damages shall be shared equally between MAYO and SORRENTO and any other amounts received, including compensatory damages or damages based on a loss of revenues which exceed the out-of-pocket costs and expenses incurred by SORRENTO, shall be deemed to be Net Sales of Royalty-Bearing Products in the fiscal quarter received.

c) If SORRENTO fails, within one hundred twenty (120) days after receiving notice of a potential infringement, to institute an action against such infringer or notifies MAYO that it does not plan to institute such action, then MAYO shall have the right to do so at its own expense. SORRENTO shall cooperate with MAYO in such effort including being joined as a party to such action if necessary. MAYO shall be entitled to retain all damages or costs awarded in such action. Should either MAYO or SORRENTO be a party to a suit under the provisions of this Article and thereafter elect to abandon such suit, the abandoning party shall give timely notice to the other party who may, at its discretion, continue prosecution of such suit.

6.03PATENT TERM EXTENSION. SORRENTO shall consult with MAYO in selecting the patent covering each Licensed Product for patent term extension for or supplementary protection certificate in accordance with the Applicable Laws of any country. Each Party agrees to execute any documents and to take any additional actions as the other Party may reasonably request in connection therewith.

6.04PATENT MARKING. To the extent commercially feasible, SORRENTO will mark all Licensed Products that are manufactured or sold under this Agreement with the number of each issued patent within the Patent Rights that cover such Licensed Product(s). Any such marking will be in conformance with the patent laws and other laws of the country of manufacture or sale.

6.05DEFENSE. MAYO will have the first right, but not the obligation, to take any measures deemed appropriate by MAYO, regarding (a) challenges to the Patent Rights (including interferences, inter partes review, post grant review, cover business method, ex parte examination, or derivation proceedings in the U.S. Patent and Trademark Office and oppositions in foreign jurisdictions) and (b) defense of the Patent Rights (including declaratory judgment actions). SORRENTO shall have the right to comment and participate in any such challenge or action at its request and expense, and will reasonably cooperate in any such measures if requested to do so by MAYO. Should MAYO choose not to defend that Patent Rights against any such challenges or actions then SORRENTO may do so at its own expense [...***...].

6.06THIRD PARTY LITIGATION. In the event a third party institutes a suit against SORRENTO for infringement of intellectual property involving a Licensed Product, SORRENTO will promptly inform MAYO and keep MAYO regularly informed of the proceedings. SORRENTO agrees to indemnify, defend and hold harmless MAYO for any claims, demands or law suits related thereto in accordance with Article 9.

7.01USE OF NAME AND LOGO. Except to the extent required by Applicable Law (including reporting obligations with respect to public filings), neither Party will use for publicity, promotion or otherwise, any logo, name, trade name, service mark or trademark of the other Party or its Affiliates, or any simulation, abbreviation or adaptation of the same, or the name of any employee or agent of the other Party, without that Party’s prior, written, express consent. A Party may withhold such consent in that Party’s absolute discretion. MAYO’s marks include, but are not limited to the terms “MAYO®,” “MAYO Clinic®” and the triple shield MAYO logo. With regard to the use of MAYO’s name, all requests for approval pursuant to this Section must be submitted to the Mayo Clinic Public Affairs Business Relations Group, at the e-mail address [...***...] at least ten (10) business days prior to the date on which a response is needed (which time period may be waived in MAYO’s sole discretion).

8.01TREATMENT OF CONFIDENTIAL INFORMATION. Except as provided for in Section 8.02 (Right to Disclose), neither Party will disclose, use or otherwise make available the other’s Confidential Information during the Term and for three (3) years thereafter and will use at least the same degree of care it employs to protect its own confidential information.

(a)To the extent it is reasonably necessary or appropriate to fulfill its obligations or exercise its rights under this Agreement, SORRENTO may use and disclose Confidential Information of MAYO to its Sublicensees, consultants, and outside contractors on the condition that each such entity or person agrees to obligations of confidentiality and non-use at least as stringent as those herein.

a)SORRENTO will defend, indemnify and hold harmless MAYO, MAYO’s Affiliates and their respective trustees, officers, agents, independent contractors and employees (“MAYO Indemnitees”) from any and all judgments, costs, expenses, damages and liabilities (including reasonable attorneys’ fees, court costs and other reasonable expenses of litigation) (collectively, “Liabilities”) resulting from suits, claims, actions and demands, in each case brought by a third party (each, a “Third-Party Claim”), regardless of the legal theory asserted, arising out of or connected with: (i) the practice or exercise of any rights granted hereunder by or on behalf of SORRENTO or any Sublicensee; (ii) research, development, design, manufacture, distribution, use, sale, importation, exportation or other disposition of Licensed Products by or on behalf of SORRENTO or any Sublicensee; (iii) any material breach of any of SORRENTO’s obligations, representations, warranties or covenants under this Agreement; or (iv) act or omission of SORRENTO or any Sublicensee in the performance under this Agreement, including the negligence or willful misconduct of a SORRENTO Indemnitee under this Agreement. SORRENTO’s obligation to indemnify the MAYO Indemnitees pursuant to this Section 9.03(a) shall not apply to the extent that any such Liabilities are the result of a material breach by MAYO of its obligations, representations, warranties or covenants under this Agreement or MAYO’s gross negligence or willful misconduct.

b)MAYO will defend, indemnify and hold harmless SORRENTO, SORRENTO’s Affiliates and their respective trustees, officers, agents, independent contractors and employees (“SORRENTO Indemnitees”) from any and all Liabilities resulting from Third-Party Claims arising out of or occurring as a result of: (i) any material breach of any of MAYO’s obligations, representations, warranties, or covenants under this Agreement; or (ii) the gross negligence or willful misconduct of a MAYO Indemnitee under this Agreement. MAYO’s obligation to indemnify the SORRENTO Indemnitees pursuant to this Section 9.03(b) shall not apply to the extent that any such Liabilities are the result of a material breach by SORRENTO of its obligations, representations, warranties or covenants under this Agreement or SORRENTO’s gross negligence or willful misconduct.

(c) To be eligible to be Indemnified pursuant to this Section 9.03, the indemnified Person shall provide the indemnifying Party with prompt written notice of the Third-Party Claim giving rise to the indemnification obligation pursuant to this Section 9.03 and the right to control the defense (with the reasonable cooperation of the indemnified Person) or settlement any such claim; provided, however, that the indemnifying Party shall not enter into any settlement that admits fault, wrongdoing or damages without the indemnified Person’s written consent, such consent not to be unreasonably withheld or delayed. The indemnified Person shall have the right to join, but not to control, at its own expense and with counsel of its choice, the defense of any claim or suit that has been assumed by the indemnifying Party.

(d)SORRENTO will continuously carry occurrence-based liability insurance, including products liability and contractual liability, in an amount and for a time period sufficient to cover the liability assumed by SORRENTO hereunder during the Term and after, such amount being at least Five Millions Dollars (USD $5,000,000). In addition, such policy will name MAYO and its Affiliates as additional-named insureds up to the policy limit. The minimum limits of any insurance coverage required herein shall not limit SORRENTO’s liability. SORRENTO acknowledges and agrees that the rights and remedies available to MAYO hereunder shall not be limited by the amounts of SORRENTO’s insurance coverage.

(e)SORRENTO expressly waives any right of subrogation that it may have against MAYO Indemnitees resulting from any claim, demand, liability, judgment, settlement, costs, fees (including attorneys’ fees) and expenses for which SORRENTO is obligated to indemnify, defend and hold MAYO Indemnitees harmless under this Agreement.

9.04PROHIBITION AGAINST INCONSISTENT STATEMENTS. SORRENTO shall not make any statements, representations or warranties on behalf of MAYO, nor purport to accept any liabilities or responsibilities on behalf of MAYO whatsoever that are inconsistent with any disclaimer or limitation included in this section or any other provision of this Agreement.

10.01TERM. This Agreement shall become effective as of the Effective Date, and will continue in full force and effect unless and until (a) mutually terminated in writing by the Parties, or (b) otherwise terminated pursuant to and in accordance with the terms of this Agreement (the “Term”).

(a)Subject to Section 11.17 (Force Majeure) and Section 10.06, if SORRENTO commits a material breach of this Agreement, including without limitation, the failure to make any required and undisputed royalty or fee payments hereunder, MAYO may notify SORRENTO in writing of such breach specifying the nature of the breach, requiring SORRENTO to cure such breach, and stating its intention to terminate this Agreement if such breach is not cured, and SORRENTO will have (a) in the event of a material payment breach, sixty (60) days after such notice to cure such breach or (b) in the event of any other material breach (including any material breach of any diligence, milestone or similar obligation hereunder), one hundred and twenty (120) days after such notice to cure such breach. If SORRENTO fails to cure such breach within the applicable aforementioned cure period, MAYO may, at its sole discretion, terminate this Agreement by sending SORRENTO written notice of termination.

(b)Subject to Section 11.17 (Force Majeure), if MAYO commits a material breach of this Agreement, SORRENTO may notify MAYO in writing of such breach specifying the nature of the breach, requiring MAYO to make good or otherwise cure such breach, and stating its intention to terminate this Agreement if such breach is not cured, and MAYO will have sixty (60) days after such notice to cure such breach. If MAYO fails to cure such breach within the applicable aforementioned cure period, SORRENTO may, at its sole discretion, terminate this Agreement by sending MAYO written notice of termination.

10.03TERMINATION FOR SUIT. MAYO does not license entities that bring suit against MAYO or its Affiliates and as such, MAYO may immediately terminate this Agreement if SORRENTO or any Sublicensee directly or indirectly brings any action or proceeding against MAYO or its Affiliates relating to the subject matter of this Agreement, except for any suit, action or claim relating to an uncured material breach of this Agreement by MAYO or its Affiliates or otherwise to enforce or affirm the terms and conditions of this Agreement or any sponsored research agreements contemplated herein.

10.04INSOLVENCY OF SORRENTO. This Agreement terminates immediately without an obligation of notice of termination to SORRENTO in the event SORRENTO ceases conducting business in the normal course, becomes insolvent or bankrupt, makes a general assignment for the benefit of creditors, admits in writing its inability to pay its debts as they are due, permits the appointment of a receiver for its business or assets or avails itself of or becomes subject to any proceeding under any statute of any governing authority relating to insolvency or the protection of rights of creditors.

10.05TERMINATION FOR CONVENIENCE BY SORRENTO. SORRENTO may, during the Royalty Term, terminate this Agreement for no reason or for any reasons upon six (6) months’ written notice to MAYO.

10.06TERMINATION OF A LICENSED PRODUCT DUE TO ABANDONMENT OR FAILURE TO EXERCISE COMMERCIALLY REASONABLE EFFORTS. If SORRENTO and its Affiliates and Sublicensees have not undertaken any development, commercialization, or other Exploitation of a particular Licensed Product in accordance with the then current Development Plan, or otherwise have failed to exercise their required Commercially Reasonable Efforts with respect to a particular Licensed Product set forth on the then current Development Plan in accordance with the then current Development Plan, and, in either case, have failed to remedy such breach within sixty (60) days of receiving notice thereof by MAYO then, in either case, and as MAYO’s exclusive remedy and as SORRENTO’s sole liability, MAYO may, at its sole discretion, but only with respect to such Licensed Product, terminate SORRENTO’s rights to such Licensed Product or convert SORRENTO’s license to such Licensed Product to non-exclusive, in either case by providing SORRENTO written notice of such termination or conversion. For the avoidance of doubt, exercise of the foregoing rights by MAYO will not terminate or amend any other rights SORRENTO has to any other Licensed Products.

10.07RETURN/DESTRUCTION OF CONFIDENTIAL INFORMATION / MATERIALS / LICENSED PRODUCT. Subject to Section 10.08 (Effect of Termination) below (including the sell off period set forth therein), in the event of termination of this Agreement by MAYO pursuant to Sections 10.02(a), 10.03, 10.04, or 10.06, and at MAYO’s sole discretion, SORRENTO shall either return the Confidential Information, Materials and Licensed Product to MAYO or destroy it. If SORRENTO is instructed to destroy the Confidential Information, Materials and Licensed Product, SORRENTO shall provide MAYO certification of action within thirty (30) days from the date of destruction.

a)By MAYO for Cause or Abandonment or by SORRENTO without Cause. Without limiting SORRENTO’s rights under any sponsored research agreement(s) contemplated herein, termination of this Agreement (i) by MAYO under Sections 10.02(a), 10.03, 10.04, or 10.06, or (ii) by SORRENTO under Section 10.05 will result in termination of SORRENTO’s license rights under Section 2.01 (provided that, in the case of termination by MAYO under Section 10.06, only SORRENTO’s rights with respect to the terminated Licensed Product shall be so terminated), subject to SORRENTO’s rights under the following paragraph.

Without limiting SORRENTO’s rights under any sponsored research agreement(s) contemplated herein, upon termination of this Agreement (i) by MAYO under Sections 10.02(a), 10.03, 10.04, or 10.06, or (ii) by SORRENTO under Section 10.05, in the event MAYO provides notice to SORRENTO, SORRENTO shall assign to MAYO all right, title and interest in and to all development information to the extent solely relating to SORRENTO’s or anyone acting on their behalf, exercise of the licenses granted and subsequently hereunder, including but not limited to, any such information in vitro studies, toxicology, pharmacokinetic, efficacy, clinical and other technical data and all correspondence to and from regulatory agencies to the extent solely relating to approval of terminated Licensed Products generated by SORRENTO and/or its

Affiliates, contractors and agents hereunder (hereinafter “Development Information”). If so required hereunder, SORRENTO shall use Commercially Reasonable Efforts to provide any such Development Information to MAYO within thirty (30) days of the date of termination. Upon termination of this Agreement by MAYO under Sections 10.02(a), 10.03 or 10.04 or by SORRENTO under Section 10.05, SORRENTO shall cease manufacturing, processing, producing, using, importing or selling all terminated Licensed Products; provided, however, that SORRENTO and its Affiliates and Sublicensees may (i) finish manufacturing terminated Licensed Products that are in the process of being manufactured at the time of termination, and (ii) continue to sell in the ordinary course of business for a period of one year (1) year those quantities of terminated Licensed Products which are fully manufactured and in SORRENTO’s normal inventory at the date of termination (or for which manufacture is completed in accordance with subclause (i) hereof), if (a) all monetary obligations of SORRENTO to MAYO have been satisfied and (b) royalties on such sales are paid to MAYO in the amounts and in the manner provided in this Agreement.

b)By SORRENTO for Cause. Termination of this Agreement by SORRENTO under Section 10.02(b) for material breach of this Agreement by MAYO, will result in the voiding of Section 3.02, licenses in Section 2.01 and the covenant set forth in Section 2.04 becoming irrevocable subject to all other applicable terms and conditions of this Agreement remaining in effect to the extent necessary for the continued payment of royalties by SORRENTO for Net Sales of Royalty Bearing Products. For the avoidance of doubt, any royalties that would be due notwithstanding SORRENTO’s termination pursuant to this Section 10.08(b), will continue to accrue and be payable to MAYO in accordance with the terms and conditions of this Agreement.

c)Expiration. Upon expiration of the Royalty Term with respect to a particular country, all rights and licenses granted to SORRENTO under this Agreement and the covenant set forth in Section 2.04, in each case with respect to such country, will become fully paid, irrevocable (except otherwise provided herein), and royalty free. For the avoidance of doubt, milestone payments due under Section 3.02 shall still remain in effect after the Royalty Term.

10.09SURVIVAL. The termination or expiration of this Agreement does not relieve either Party of its rights and obligations that have previously accrued. Subject to Sections 10.08(a) and 10.08(b), all rights granted immediately revert to MAYO after the Term. Rights and obligations that by their nature prescribe continuing rights and obligations shall survive the termination or expiration of this Agreement including Sections 4.02 (Accounting), 9.03 (Indemnification and Insurance), 10.07 (Return/Destruction of Material/Licensed Product), 10.08 (Effect of Termination), 10.09 (Survival) and Articles 1 (Definitions), 7 (Use of Name), 8 (Confidentiality) and 11 (General Provisions).

11.16WAIVER. The failure of either Party to complain of any default by the other Party or to enforce any of such Party’s rights, no matter how long such failure may continue, will not constitute a waiver of the Party’s rights under this Agreement.

No part of this Agreement may be waived except by the further written agreement of the Parties.

No Party shall be liable for a failure or delay in performing any of its obligations under this Agreement to the extent that such failure or delay is due to causes beyond the reasonable control of the affected Party, including: (a) acts of God; (b) fire, explosion, or unusually severe weather; (c) war, invasion, riot, terrorism, or other civil unrest; (d) governmental laws, orders, restrictions, actions, embargo or blockages; (e) national or regional emergency; (f) strikes or industrial disputes at a national level which directly impact the affected Party’s performance under this Agreement; (g) epidemics, pandemics, or disease outbreak (including the novel coronavirus (COVID-19) pandemic) and steps required under Applicable Law in light of any such epidemic, pandemic, or disease outbreak; (h) regulatory delays, including any delay or inaction by a Regulatory Authority; or (i) other similar cause outside of the reasonable control of such Party (“Force Majeure”); provided that the Party affected shall promptly notify the other of the Force Majeure condition and shall eliminate, cure or overcome any such causes and to resume performance of its obligations as soon as possible.
