are being brought to bear to advance the Products through early clinical development;

 

		1.	Definitions.

 

a.       “Affiliate”
shall mean any corporation or other entity that directly or indirectly controls, is controlled by, or is under common control with, another
corporation or entity. Control means direct or indirect ownership of, or other beneficial interest in, more than fifty percent (50%) of
the voting stock, other voting interest, or income of a corporation or other entity.

 

b.       “Generic
Product” refers to a product having the same or substantially same active pharmaceutical ingredient of the Patent Product that
obtained a marketing approval by means of a procedure for establishing equivalence to the Patent Product under a 21 U.S.C. Section 355(b)(2)
filing in the United States or any substantially equivalent procedures in any foreign countries.

 

c.       “Cover”
or “Covered By” shall mean (i) infringes, in the case of a claim in an issued patent, or (ii) would infringe the claim
if it existed in an issued patent, in the case of a claim in a pending application provided however if a pending application has not
been granted within five (5) years of the first substantive patent office action considering the patentability of any claim by the
relevant patent office in the country or territory in which such application is pending (after which time such pending application
shall cease to Cover a product or service for purposes of this Agreement and shall have no impact under this Agreement unless and
until such former pending application becomes an issued application).

 

     

     

    

 

d.       “Designee”
shall mean a corporation or other entity that is employed by, under contract to, or in partnership with (i) Company, (ii) a Sublicensee,

make, use, sell, promote, distribute, market, import, or export Products.

 

e.       “Field”
shall mean all uses including all ocular indications except diabetic retinopathy, which shall included but is not limited to Dry Age Related
Macular Degeneration and Stargardt Disease. Columbia will notify Company within twelve months of the Effective Date whether diabetic retinopathy
could be added to the Field.

 

f.       “License
Year” shall mean the one year period from the Effective Date of this Agreement or an anniversary thereof to the next anniversary
of the Effective Date.

 

g.       “Materials”
shall mean the tangible physical material, if any, delivered to Company hereunder, any progeny thereof developed by Company, its Affiliates
or Sublicensees, and any derivatives thereof developed by Company, its Affiliates or Sublicensees that are not Covered By the Patents.
Any Materials delivered to Company hereunder shall be listed in Exhibit B hereto.

 

h.       “Net
Sales” shall mean the greater of the gross invoice or contract price charged to Third Party customers for the Product or the actual
consideration paid by Third Party customers for the Product. For all Products used or consumed by any Third Party, Company shall be entitled
to deduct [***] from Net Sales in lieu of all other deductions such as taxes, shipping charges, allowances, and the like prior to calculating
royalties due. The intent of this definition of Net Sales is to allow Columbia to derive a royalty on the end sale of a Product to the
first Third Party.

 

If a Product is sold as
part of a Combination Product, the Net Sales of such Product for the purpose of calculating royalties and sales-based milestones
owed under this Agreement for sales of such Product, shall be determined as follows: first, Company shall determine the actual Net
Sales of such Combination Product (using the above provisions) and then such amount shall be multiplied by the fraction A/(A+B),
where A is the invoice price of such Product, if sold separately, and B is the aggregate invoice price of each other drug, device,
or biological product in the Combination Product, if sold separately. If any other drug, device, or biological product in the
Combination Product is not sold separately in a country, Net Sales for such country shall be calculated by multiplying actual Net
Sales in such country of such Combination Product by a fraction A/C where A is the invoice price of such Product if sold separately,
and C is the invoice price of the Combination Product. If neither Product nor any other drug, device, or biological product in the
Combination Product is sold separately, the adjustment to Net Sales shall be determined by the Parties in good faith to reasonably
reflect the fair market value of the contribution of such Product in the Combination Product to the total fair market value of such
Combination Product. Combination Product” means: (a) a product consisting of one or more products that are separately
sold that are packaged together with a Product and after such packaging are sold as a single package or as a unit for a single
price; or (b) a drug, device or biological product packaged and sold separately that is sold as a unit with a Product for a single
price.

		4.	Fees, Royalties and Payment.

 

a.       Importance
of Technical Information and Materials. Company has requested, and Columbia has agreed, to grant certain rights to Technical
Information and Materials. Company requires these rights in order to develop and commercialize the technology licensed hereunder.
Because of the importance of Technical Information and Materials, Company has agreed to pay certain royalties to Columbia on Other
Products, as specified herein, even if it is not Covered By a Patent, in order to obtain rights to Technical Information and
Materials. Company has agreed to these payments because of the commercial value of Technical Information and Materials, separate and
distinct from the commercial value of the Patents. Company acknowledges that it would not have entered into this Agreement without
receiving the rights to the Technical Information and Materials specified in Section 2. Company further acknowledges that licenses
to Technical Information, Materials, and each patent and application within the definition of Patents were separately available from
a license to the Patents, and that for convenience and because of the preference of Company, the parties executed a combined license
to the Patents, Technical Information, and Materials.

 

b.       In consideration
of the licenses granted under Section 2a of this Agreement, the Company shall pay to Columbia as follows:

 

(i) License Fee: A nonrefundable, non-recoverable
and non-creditable license fee in the sum of [***], payable within ninety days after execution of this Agreement

 

(ii) Royalties:

 

(A)       With
respect to sales of Products by Company or Sublicensee, their Designees or their Affiliates, in the Territory, a nonrefundable and non-recoverable
royalty of:

 

		(1)	[***] on Net Sales of Patent Products; and

 

		(2)	[***] on Net Sales of Regulatory Exclusive Products; and

 

		(3)	[***] on Net Sales of Other Products.

 

In the event that a Generic Product is available in a certain country,
the royalties set forth in Section 4b will be reduced to [***] in such country for the Product referenced by the Generic Product.

 

(B)       Notwithstanding
the foregoing, commencing on the second anniversary of the commercial launch of any Product, the Company shall pay to Columbia a nonrefundable
and non-recoverable minimum royalty payment as follows: (i) [***], payable annually within [***] following the [***] of the first bona
fide commercial sale of a Product by Company, a Sublicensee, a Designee, or any of their Affiliates, to a Third Party customer (the
 “First Commercial Sale”), and (ii) [***] payable [***] on the first business day of [***] following the [***] anniversary
of the First Commercial Sale and every anniversary thereafter until the end of the royalty term as specified in Section 16b.  Each
such minimum royalty payment will be credited against earned royalties accrued during the same calendar year in which the minimum royalty
payment is due and payable.  To the extent minimum royalty payments exceed the earned royalties accrued during the same calendar
year, this excess amount cannot be carried over to any other year, either to decrease the earned royalties due in that year or to decrease
the minimum royalty payments due in that year.

 

    7

     

    

 

c.       In consideration
of Company’s right to sublicense third parties granted under Section 2b of this Agreement, Company shall pay to Columbia the following
nonrefundable, non-recoverable and non-creditable amounts (the intention of the parties being that Columbia shall receive consideration
equivalent to a full pass-through royalty on all sales of Products by Sublicensees as set forth in Section 4b(ii)(A)):

 

(i) Other Payments: [***] of any and all
other gross revenues (excluding royalties), fees, payments and consideration (including a portion of any equity securities of any cross-licensing
rights granted by Sublicensee to Company), including without limitation, any upfront, milestone or lump sum payments, received by Company
from Sublicensees, their Designees or their Affiliates as full or partial consideration for the grant of any sublicense by Company pursuant
to Section 2b of this Agreement but shall not include (a) for research and development conducted as agreed with the Sublicensee and conducted
after the date on which the Sublicensee actually signed the sublicense agreement and which payments are not in excess of Company’s
fully burdened costs, fees, expenses, and royalties related to performing any research and development relating to the Products, (b) any
consideration received for an equity interest in, extension of credit to or other investment in Company or its Affiliates to the extent
such consideration does not exceeds [***] of fair market value of the equity or other interest received as determined by agreement of
the parties or by an independent appraiser mutually agreeable to the parties, or (c) the receipt of any equipment or the use of any real
estate where such equipment or real estate is used for the mutual benefit of the Sublicensee and the Company or where the Company pays
fair market value for such equipment or real estate.

 

(ii) Company will pay Columbia an amount equal
to [***] of Priority Review Voucher Revenue. If Company has not sold the Priority Review Voucher [***]of receipt of the Priority Review
Voucher, royalties due under Section 3b(ii)(A)1 shall [***] of Net Sales of Patent Products.

 

d.       Development
Milestone Payments: In the event that the Company, Sublicensees, or their Affiliates (collectively “Developer”) develops
a Product for commercial sale in the Territory, the following nonrefundable, non-recoverable and non-creditable milestone payments shall
be made by Company to Columbia with respect to the first Product as follows:

 

	Milestone	 	Payment
	[***]	 	[***]
	[***]	 	[***]
	[***]	 	[***]
	[***]	 	[***]
	[***]	 	[***]

 

The above milestone payment shall be paid on the
first Product and first indication only.

 

e.       Duration
of Other Product Royalties. Royalties on Other Products shall be payable on a country-by-country and product-by-product basis for
the longer of [***] years after the first bona fide commercial sale of an Other Product in a country or expiration
of any market exclusivity period granted by a regulatory agency

 

f.       Highest
Royalty Due. If a Product is covered by both the definition of Patent Product, Regulatory Exclusivity Product and Other Product,
but not a Generic Product, Columbia shall be entitled to the Patent Product royalty rate on the Product. Columbia shall not be
entitled to more than one royalty payment on the same Product sale under Section 4. To the extent a Product ceases being a Patent
Product, but is still an Other Product, Columbia shall be entitled to the Other Product royalty rate on the Product, but only for
such time as specified in Section 4e. By way of example, but not by way of limitation, if the manufacture of a Product is Covered by
the claim of a Patent, and the manufacture of that Product also incorporates in part Technical Information, Company must pay the
royalty specified in Section 4b(ii)(A)(1). If, after some period of time (for example, five years) of paying the royalties specified
in Section 4b(ii)(A)(1) on the Product, the Product ceases to be a Patent Product, Company must continue to pay royalties on the
Product pursuant to Section 4b(ii)(A)(3) for the duration specified in Section 4e measured from the first bona fide commercial sale
of the Patent Product on a country-by-country and product-by-product basis.

 

    8

     

    

 

g.       No
Non-Monetary Consideration. Without Columbia’s prior written consent, which shall not be unreasonably withheld or delayed, Company,
Sublicensees, Designees, and Affiliates of the foregoing, shall not solicit or accept any consideration for the sale of any Product other
than as will be accurately reflected in Net Sales. Furthermore, Company shall not enter into any transaction with any Affiliate that would
circumvent its monetary or other obligations under this Agreement.

 

 h.       Rate Adjustment on Challenge; Payment of Costs and Expenses.

 

(i)                
In the event Company (or any entity or person acting on its behalf) initiates any proceeding any claim challenging the validity
or enforceability of any Patent in any court, administrative agency or other forum (“Challenge”), all royalty rates, minimum
royalties, and other payment rates set forth in Sections 4b(ii) and 4c shall be automatically [***] on and after the date of such challenge
for the remaining term of this Agreement.

 

(ii)             
Company shall pay all costs and expenses incurred by Columbia (including actual attorneys’ fees) in connection with defending
a Challenge. Columbia may bill Company on a quarterly basis with respect to such costs and expenses, and Company shall make payment within
[***] days after receiving an invoice from Columbia.

 

(iii)           
In the event at least one claim of a Patent that is subject to a Challenge survives the Challenge by not being found invalid or
unenforceable, regardless of whether the claim is amended as part of the Challenge, all royalty rates, minimum royalties, and other payment
rates set forth in Sections 4b(ii) and 4c shall be [***] on and after the date of such finding for the remaining term of this Agreement.

 

Company acknowledges and agrees that the provisions set forth in this
Section 4h reasonably reflect the value derived from the Agreement by Company in the event of a Challenge. In addition, Company acknowledges
and agrees that any payments made under this Section 4h shall be nonrefundable and non-recoverable for any reason whatsoever.

 

i.       Sale
Below Fair Market Value. In the event that Company, Sublicensees, Designees or their Affiliates sell Product to a Third Party for
subsequent sale, rental, lease or other transfer to whom it also sells other products, the price for Licensed Product shall not be established
such that Net Sales is below fair market value with the intent of increasing market share for other products sold by Company, Sublicensees,
Designees or their Affiliates to such Third Party or for the purpose of reducing the amount of royalties payable on the Net Sales of
Product. If the sale of Product under such circumstances results in Net Sales below the fair market value of Product, then the Net Sales
of Product in such transaction shall be deemed to be the fair market value for purposes of calculating payments owed to Columbia under
this Agreement. These provisions will not apply to the transfer of Product to a Third Party for humanitarian or compassionate use or
for use in clinical trials or research whereby Company, Sublicensee or any Designee or Affiliate of any of the foregoing will not receive
any monetary value for such Product.

inspect and copy such books and records for purposes of verifying the accuracy of the amounts paid under this Agreement. The review may
cover a period of not more than [***] years before the first day of the [***] in which the review is requested. In the event that such
review shows that Company has underpaid royalties by [***] or more with respect to any [***], or if such underpayment is in excess of
[***] for any [***], or an aggregate of [***] for any [***], Company shall pay, within [***] days after demand by Columbia, the costs
and expenses of such review (including the fees charged by Columbia’s accountant and attorney involved in the review), in addition
to amount of any underpayment and any interest thereon. Company agrees to cooperate fully with the independent accountant or auditor and
Columbia’s in house attorney in connection with any such review. For the sake of clarity, the audit will be performed by the independent
accountant or auditor. During the review, Company shall provide Columbia’s accountant or auditor and in-house attorney to audit
and test for completeness, including without limitation, with information relating to sales, inventory, manufacturing, purchasing, transfer

and customers) (collectively, “Company Documentation”). Columbia agrees that all Company Documentation will be reviewed by
the independent accountant or auditor and Columbia’s in house attorney only.

compounded monthly, either at the rate of [***] per annum, or in Columbia’s sole discretion, at the U.S. prime rate plus [***]
as published by the Wall Street Journal on the last day of the applicable billing period. Any interest charged or paid in excess of
the maximum rate permitted by applicable New York State Law shall be deemed the result of a mistake and interest paid in excess of
the maximum rate shall be credited or refunded (at the Company’s option) to Company.

 

h.              
Company shall reimburse Columbia for any costs and expenses incurred in connection with collecting on any arrears of Company with

payment of a [***] fee, Columbia will agree to a [***] extension of the due date for such milestone. In the event after completion
of Phase I Trials (as per Section 6a(ii)) there are unforeseen changes in clinical or regulatory development that Company believes
would affect the timely achievement of any milestone, Company may request an extension from Columbia for such milestone, which will
not be unreasonably withheld or delayed. Notwithstanding any other provisions of this Agreement, failure to achieve any of

Columbia, by counsel it selects to whom Company has no reasonable objection, in consultation with Company and any counsel appointed
by the Company, will prepare, file, prosecute and maintain all Patents in Columbia’s name and in countries designated by the Company.
Columbia shall instruct its patent counsel (1) to copy Company on all correspondence related to Patents (including copies of each patent
application, office action, response to office action, request for terminal disclaimer, and request for reissue or reexamination of any
patent or patent application) and (2) as requested by Company, to provide an update as to the current status of all Patents. The parties
agree that consultation between the parties relating to the Patents under this Section 11 shall be pursuant to a common interest in the
validity, enforceability and scope of the Patents. Each party shall treat such consultation, along with any information disclosed by each
party in connection therewith (including any information concerning patent expenses), on a strictly confidential basis, and shall not
disclose such consultation or information to any party without the other party’s prior written consent. If Company seeks to challenge
the validity, enforceability or scope of any Patent, Columbia’s consultation obligation under this Section 11a shall automatically
terminate; for the avoidance of doubt, any such termination shall not affect Company’s confidentiality and nondisclosure obligations
with respect to consultation or disclosure of information prior to such termination, and shall not affect any other provisions of this
Agreement (including Company’s reimbursement obligation under Section 11b).

 

    15

     

    

 

b.               Company
will reimburse Columbia for the actual fees, costs, and expenses Columbia has incurred prior to [***] not to exceed [***] upon
receiving Columbia’s itemized invoices and will pay the actual fees, costs, and expenses that Columbia incurs following
[***]in preparing, filing, prosecuting and maintaining the Patents and those past patent expenses Columbia incurred prior to [***]
relating to the following patents and patent applications to which Patents claim priority, issue fees, working fees, maintenance
fees and renewal charges (collectively “Patent Expenses”). Columbia, using reasonable efforts, estimates that
unreimbursed patent expenses incurred through [***] upon receiving Columbia’s itemized invoices under Section 11a in
connection with the Patents set forth in Exhibit A are $ [***], and shall be reimbursed in full by Company to Columbia within seven
(7) business days after the Effective Date and receiving Columbia’s itemized invoice. Patent Expenses incurred by Columbia
after [***] shall be reimbursed to Columbia by Company within fourteen (14) days of receiving Columbia’s itemized invoice.
Pursuant to Section 1(e), should the diabetic retinopathy indication be licensed to another party, Columbia agrees to provide a
reduction on a pro rata credit basis of the patent expenses to the Company. However, at Columbia’s election, Columbia may
require advance payment of a reasonable estimate of future Patent Expenses, and Columbia may require the Company to make such
payment up to three months prior to the date Columbia has chosen for the legal work to be completed. In any event, Columbia will
give at least 14 days’ notice to the Company prior to the date the advance payment is due. Any unused balance, if any, will be
credited towards future Patent Expenses, or upon Company’s written request, returned to the Company. Within fourteen (14) days
of receiving an invoice from Columbia for any Patent Expenses incurred in excess of the reasonable estimate, Company shall reimburse
Columbia for such excess amount. Upon failure of Company to pay Patenting Expenses for any Patent(s) as required by this Section
11b, Columbia may abandon any said Patent(s) in its sole discretion. In such event, Columbia will provide notice of abandonment to
Company.

 

c.               
Subject to Sections 11d and 11f, Columbia shall have the sole right to initiate, control, defend and/or settle any proceedings
involving the validity, enforceability or infringement of any Patents when in its sole judgment such action may be necessary, proper,
and justified.

 

 

d.               Upon
written notice to Columbia, Company may request that Columbia take steps to stop a third party who is selling a product that does or
will compete with a Product sold or being developed by Company or any of its Affiliates (but not a Sublicensee, or Sublicensee
Affiliate) (“Third Party Infringer”) from infringing an issued patent falling within the definition of Patents by
providing Columbia with written evidence demonstrating prima facie infringement of specific claims of such Patent. Company
shall have the right to initiate legal proceedings against any such Third-Party Infringer in its own name and at Company’s
sole expense, unless Columbia, not later than ninety (90) days after receipt of such notice, either (i) causes such infringement to
cease or (ii) initiates legal proceedings against the Third-Party Infringer. Company will provide all assistance reasonably
requested by Columbia and will not make any admission or assert any position in any legal or administrative proceeding that is
inconsistent with or adverse to any position asserted by Columbia in any proceedings against the Third Party Infringer, without
Columbia’s prior written consent. Notwithstanding the foregoing, Columbia shall have no obligation to assert more than one
Patent in one jurisdiction against the Third-Party Infringer. In the event that Columbia does not cause infringement to cease or
fails to initiate legal proceedings as set forth above and Company initiates legal proceedings against the Third Party Infringer,
Columbia will join the action as a co-plaintiff if the court determines that Columbia is an essential party to the action. Any
proposed disposition or settlement of a legal proceeding filed by Company to enforce any issued patent falling within the definition
of Patents against any Third-Party Infringer shall be subject to Columbia’s prior written approval, which approval shall not
be unreasonably withheld or delayed. Notwithstanding the foregoing, Company’s rights under this Section 11d shall apply only
to claims of Patents that are exclusively licensed to Company under this Agreement and only in the Field and Territory which are
exclusively licensed to Company under this Agreement

 

    16

     

    

 

e.               
Any recovery, whether by way of settlement or judgment, from a third party pursuant to a legal proceeding initiated in accordance
with Section 11d shall first be used to reimburse the party initiating such legal proceeding for its actual fees, costs and expenses incurred
in connection with such proceeding. Any remaining amounts from any such settlement or judgment shall be divided as follows: (A) Columbia
shall retain or receive, as applicable, the royalty that it would have otherwise received under Section 4b(ii) had such activities been
performed by Company, and (B) all other such amounts (including any punitive or exemplary damages) shall be divided [***] to the party
who initiated or carried on the proceedings and [***] to the other party.

 

f.                
In the event a party initiates or defends a legal proceeding concerning any Patent pursuant to Section 11, the other party shall
cooperate fully with and supply all assistance reasonably requested by the party initiating such proceeding, including without limitation,
joining the proceeding as a party if requested. The party that institutes any legal proceeding concerning any Patent pursuant to Section
11 shall have sole control of that proceeding.

the “Claims”), (i) the discovery, development, manufacture, packaging, use, sale, offering for sale, importation, exportation,
distribution, rental or lease of Products, even if altered for use for a purpose not intended, (ii) the use of Patents, Materials or Technical

to indemnify Columbia if the Claims are the direct result of Columbia’s gross negligence or willful misconduct. Company shall reimburse
Columbia for the actual fees, costs, and expenses (including attorneys’ fees) that it may incur in enforcing this provision.

 

b.       Company
shall maintain, during the term of this Agreement, commercial general liability insurance (including product liability and
contractual liability insurance applicable to Company’s indemnity obligations under Section 12a) with reputable and
financially secure insurance carriers reasonably acceptable to Columbia to cover the activities of Company, Sublicensees, Designees,
and their Affiliates, for minimum limits of [***] combined single limit for bodily injury and property damage per occurrence and in
the aggregate. Such insurance shall include Columbia, its trustees, faculty, officers, employees and agents as additional insureds.
Company shall furnish a certificate of insurance evidencing such coverage, with thirty days’ written notice to Columbia of
cancellation or material change in coverage. The minimum amounts of insurance coverage required herein shall not be construed as
creating any limitation on the Company’s indemnity obligation under Section 12a of this Agreement.

 

    17

     

    

 

c.       Company’s
insurance shall be primary coverage; any insurance Columbia may purchase shall be excess and noncontributory. The Company’s insurance
shall be written to cover claims incurred, discovered, manifested, or made during or after the expiration of this Agreement.

 

d.       Company
shall at all times comply with all statutory workers’ compensation and employers’ liability requirements covering its employees
with respect to activities performed under this Agreement.

definition of Patents, Company shall mark all Patent Products, where reasonably practicable, made, sold, offered for sale, imported, or
otherwise disposed of by Company under the license granted in this Agreement with the words “Patent Pending,” and following
the issuance of one or more patents, with the numbers of such patents. The Company shall cause its Affiliates, and its Sublicensees and
Designees and their Affiliates, to comply with the marking requirements of this Section 13 where reasonably practicable.

 

		14.	Export Control Laws.

 

Company agrees to comply with U.S. export laws and
regulations pertaining to the export of technical data, services and commodities, including the International Traffic in Arms Regulations
(22 C.F.R. § 120 et seq.), the Export Administration Regulations (15 C.F.R. § 730 et seq.), the regulations administered by
the Treasury Department’s Office of Foreign Assets Control (31 C.F.R. § 500, et seq.), and the Anti-Boycott Regulations (15
C.F.R. § 760). The parties shall cooperate with each other to facilitate compliance with these laws and regulations.

 

Company understands that sharing controlled technical
data with non-U.S. persons is an export to that person’s country of citizenship that is subject to U.S. export laws and regulations,
even if the transfer occurs in the United States. Company shall obtain any necessary U.S. government license or other authorization required
pursuant to the U.S. export control laws and regulations for the export or re-export of any commodity, service or technical data covered

later than sixty (60) days after notice of any breach given by the non-breaching party.

 

		16.	Term of Agreement.

 

a.       This
Agreement shall be effective as of the Effective Date and shall continue in full force and effect until its expiration or termination

In addition, upon any termination of this Agreement

Information”) during the term of this Agreement, and prior to its termination, to the extent such Company Technical Information
is solely and directly related to the Company’s efforts to develop Products; Columbia shall have the right to use such Company Technical
Information for any purpose whatsoever on a non-exclusive basis, including the right to sublicense same to future licensees, and Company
will provide Columbia (and/or its future licensees) access to any regulatory information filed or authorized by Company with any U.S.

Products under such Company Patents. Company agrees upon request, to enter into good faith negotiations with Columbia or Columbia’s
future licensee(s), for the purpose of granting exclusive licensing rights (subject to pre-existing licenses) to said Company Patents
in a timely fashion and under commercially reasonable terms. In the event that Columbia grants a license to a Third Party to intellectual
property that includes Company Technical Information or Company Patents, the Parties will negotiate in good faith Company’s share
of any net revenue received by Columbia from such license taking into consideration Company’s contribution to the intellectual property
licensed to such Third Party. In the event that this Agreement is terminated by either Party under Section 17, Company will transfer the
ownership of the Orphan Drug Designation and Orphan Medicinal Product Designation promptly after the effective date of termination of
this Agreement to Columbia.

to initiate legal proceedings pursuant to Section 11: (i) upon written notice to Company if Columbia elects to terminate in accordance
with Section 6b; (ii) upon written notice to Company for Company’s material breach of the Agreement and Company’s failure
to cure such material breach in accordance with Section 15b; (iii) in the event Company becomes insolvent or is generally not paying its
debts as such debts become due; (iv) in the event Company ceases to conduct business as a going concern; and (v) in the event Company
(or any entity or person acting on its behalf) initiates any proceeding challenging the validity or enforceability of any Patent in any
court, administrative agency or other forum. Termination under (ii) – (v) shall be effective upon date of notice sent pursuant to
Section 17.

 

d.       Upon
any termination of this Agreement pursuant to Section 16c, all sublicenses granted by the Company under it shall be assigned to Columbia,
upon request and at Columbia’s discretion, provided that Columbia’s obligations under such sublicense shall be consistent
with and not exceed Columbia’s obligations to Company under this Agreement and provided that such sublicense agrees in a writing
sent to Columbia to assume all obligations of this Agreement for the benefit of Columbia, including the obligations to make all payments
due under this Agreement, including but not limited to those specified in Section 4b, 4c, 4d, 4h and 11b.

of this Agreement.

 

f.       Any termination
of this Agreement shall not adversely affect any rights or obligations that may have accrued to either party prior to the date of termination,
including without limitation, Company’s obligation to pay all amounts due and payable under Sections 4 (including the minimum royalties
accrued under subsection b(ii)(B) thereof and any payments required under subsection h thereof), 5 and 11 hereof.

 

g.       Upon
any termination of this Agreement for any reason other than the expiration of this Agreement under Section 16b or Company’s failure
to cure a material breach of this Agreement under Section 16c(ii), Company, Sublicensees, Designees, and their Affiliates shall have the
right, for one year or such longer period as the parties may reasonably agree, to dispose of Products or substantially completed Products
then on hand, and to complete orders for Products then on hand, and royalties shall be paid to Columbia with respect to such Products
as though this Agreement had not terminated. If this Agreement expires under Section 16b, then the Company shall thereafter be free to
use the Technical Information and Materials without any further obligation to Columbia.

 

h.       Notwithstanding
anything to the contrary in the Agreement, to the extent the manufacture of a Product is Covered By an issued patent within the definition
of Patents and occurs prior to the expiration of such issued patent, the sale of that Product after the expiration date of the issued
patent shall still constitute a royalty-bearing sale under Section 4.

or to such other address as a party may specify
by notice hereunder.

 

18.       Assignment.
This Agreement and all rights and obligations hereunder may not be assigned by either party without the written consent of the other party
except in connection with the sale of all or substantially all of the assets of such party or the division to which this agreement relates.
Any attempt to assign without compliance with this provision shall be void.

 

19.       Waiver
and Election of Remedies. The failure of any party to insist upon strict adherence to any term of this Agreement on any occasion shall
not be considered a waiver or deprive that party thereafter of the right to insist upon strict adherence to that term or any other term
of this Agreement. All waivers must be in writing and signed by an authorized representative of the party against which such waiver is
being sought. The pursuit by either party of any remedy to which it is entitled at any time or continuation of the Agreement despite a
breach by the other shall not be deemed an election of remedies or waiver of the right to pursue any other remedies to which it may be
entitled.

 

    21

     

    

 

20.       Binding
on Successors. This Agreement shall be binding upon and inure to the benefit of the parties and their respective successors and assigns
to the extent assignment is permitted under this Agreement.

 

21.       Independent
Contractors. It is the express intention of the parties that the relationship of Columbia and the Company shall be that of independent
contractors and shall not be that of agents, partners or joint venturers. Nothing in this Agreement is intended or shall be construed
to permit or authorize either party to incur, or represent that it has the power to incur, any obligation or liability on behalf of the
other party.

 

22.       Entire
Agreement; Amendment. This Agreement, together with the Exhibits, sets forth the entire agreement between the parties concerning the
subject matter hereof and supersedes all previous agreements, written or oral, concerning such subject matter. This Agreement may be amended
only by written agreement duly executed by the parties.

 

23.             
Severability. In the event that any provision of this Agreement is held by a court of competent jurisdiction to be unenforceable
because it is invalid, illegal or unenforceable, the validity of the remaining provisions shall not be affected, and the rights and obligations
of the parties shall be construed and enforced as if the Agreement did not contain the particular provisions held to be unenforceable,
unless such construction would materially alter the meaning of this Agreement. By way of example, but not by way of limitation, Sections
4h(i), 4h(ii) and 4h(iii) are intended by Company and Columbia to be severable from each other, such that if one clause is found to be
unenforceable, the other clauses remain operative and in effect.

 

24.No Third-Party Beneficiaries.
Except as expressly set forth herein, the parties hereto agree that there are no third-party beneficiaries of any kind to this Agreement.

 

25.       Governing
Law. This Agreement shall be governed by and construed in accordance with the internal substantive laws of the State of New York as
applicable to agreements made and wholly performed within the State of New York, and without reference to the conflict or choice of laws
principles of any jurisdiction. Unless otherwise separately agreed in writing, the parties agree that any and all claims arising under
or related to this Agreement shall be heard and determined only in either the United States District Court for the Southern District of

themselves to the exclusive and personal jurisdiction of those courts and irrevocably waive any and all rights any such party may now
or hereafter have to object to such jurisdiction or the convenience of the forum.

 

26.       Execution
in Counterparts; Facsimile or Electronic Transmission. This Agreement may be executed in counterparts, and by facsimile or electronic
transmission. This Agreement is not binding on the parties until it has been signed below on behalf of each party.

and the Company have caused this Agreement to be executed by their duly authorized representatives as of the day and year first written
above.
