(collectively, the “Assumed Liabilities”). No assumption by Buyer of any of the Assumed Liabilities shall relieve
or be deemed to relieve Seller from any Liability under any Transaction Document with respect to any representations or warranties
or covenants made by Seller to Buyer.


 


Section 2.4          Retained
Liabilities. Except for the Assumed Liabilities, Buyer shall not assume pursuant to this Agreement or the transactions
contemplated hereby, and shall have no liability for, any Liabilities of Seller or any of its Affiliates, or any of its or their
predecessors in interest, of any kind, character or description whatsoever (“Retained Liabilities”), all of
which shall be retained by and continue to be Liabilities of Seller or its Affiliates, as applicable. Without intending to limit
the generality or effect of the foregoing, Retained Liabilities shall include the following Liabilities:


 


(a)          all Liabilities and obligations relating
to, based in whole or in part on events or conditions occurring or existing in connection with, or arising out of, Seller or the
Business as operated prior to the Closing Date, or the ownership, possession, use, operation or sale or other disposition prior
to the Closing Date of any of the Acquired Assets (or any other assets, properties, rights or interests associated, at any time
prior to the Closing Date, with the Business);


 


(b)          all Seller Expenses;


 


(c)          all Indebtedness and all Liabilities arising
in connection with, or relating to, any Indebtedness;


 


(d)          all Liabilities arising in connection with,
or relating to, Excluded Taxes;


 


(e)          all Liabilities based upon, arising out
of or otherwise in respect of any Employee Plans;


 


(f)          all Liabilities based upon, arising out
of or otherwise in respect of (i) any current or former employees or other services providers of Seller or any other member of
the Controlled Group for the period on and prior to the Closing Date; and (ii) any current or former employees or other service
providers of Seller or any other member of the Controlled Group who do not become Transferred Employees for the period following
the Closing Date;


 






    	 	 -20-	 



     


    

 


(g)          all Liabilities arising in connection with,
or relating to, the Excluded Assets;


 


(h)          all Liabilities arising in connection with,
or relating to, any real property owned, leased or otherwise used or occupied by Seller;


 


(i)          all investigation, feasibility study, mitigation,
cleanup, remediation, monitoring and other related activities or costs associated with any Release of any Hazardous Substance on
any real property leased by Seller;


 


(j)          all Liabilities arising out of or related
to Seller’s business outside of the Territory, including with respect to Contracts relating to Seller’s business outside
of the Territory;


 


(k)          all royalties or other Liabilities owed
under the Contract listed on Schedule 2.4(k); and


 


(l)          all Liabilities relating to abandoned or
unclaimed property reportable under any state or local unclaimed property, escheat or similar law where the dormancy period elapsed
prior to the Closing Date.


 


Section 2.5          Estimated
Closing Purchase Price. No later than three Business Days prior to the Closing, Seller will deliver to Buyer a statement
that will set forth Seller’s good faith calculation of the Closing Date Payment (the “Estimated Closing Purchase
Price Statement”). Such estimate of the Closing Date Payment (the “Estimated Closing Purchase Price”)
will be a good faith estimate of the Closing Date Payment. The Estimated Closing Purchase Price Statement will consist of a proposed
calculation in reasonable detail of the Estimated Closing Purchase Price, including Seller’s good faith estimate of the amount
of the Closing Date Payment and Product Inventory Value. Buyer will review the Estimated Closing Purchase Price Statement and,
if Buyer disagrees with any item set forth in such statement, it will provide written notice to Seller, along with a reasonably
detailed explanation of the same, and the Parties will attempt to resolve in good faith any such disagreements prior to the Closing.
If the Parties are unable to agree on the amounts set forth in the Estimated Closing Purchase Price Statement, the values proposed
by Seller in the Estimated Closing Purchase Price Statement will be utilized for purposes of the payment of the Estimated Closing
Purchase Price. In no event will the determination of the amounts set forth in the Estimated Closing Purchase Price Statement prejudice
a Party’s rights under Section 2.7(c).


 


Section 2.6          Payment
of Estimated Closing Purchase Price. At the Closing, Buyer will pay in cash:


 


(a)          the aggregate amount
of Closing Date Indebtedness payable to the holders of Closing Date Indebtedness designated in the direction letter delivered to
Buyer pursuant to Section 2.9(a)(v), on behalf of Seller or its Affiliates and as specified in each such holder’s
applicable payoff letter (which payoff letters will be delivered to Buyer no later than three Business Days prior to the Closing
Date and will specify the amount necessary to fully discharge all Closing Date Indebtedness owed to such Person and to release
all Liens under such Closing Date Indebtedness), to such account or accounts as directed in the applicable payoff letter or as
otherwise directed by Seller in the direction letter delivered to Buyer pursuant to Section 2.9(a)(v);


 






    	 	 -21-	 



     


    

 


(b)          on behalf of Seller,
Seller Expenses, in each case in accordance with the direction letter delivered to Buyer pursuant to Section 2.9(a)(v);
and


 


(c)          to Seller, the Estimated
Closing Purchase Price, by wire transfer of immediately available funds, pursuant to instructions delivered to Buyer no less than
three Business Days prior to the Closing Date.


 


Section 2.7          Determination
of the Final Closing Purchase Price.


 


(a)          As soon as reasonably
practicable, but no later than 90 days after the Closing Date, Buyer will prepare and deliver to Seller a statement (the “Proposed
Final Closing Purchase Price Statement”) consisting of a proposed calculation in reasonable detail of the Closing Purchase
Price (the “Proposed Final Closing Purchase Price”), including Buyer’s good faith calculation of the amount
of the Closing Date Payment and Product Inventory Value.


 


(b)          During the 30-day
period following Seller’s receipt of the Proposed Final Closing Purchase Price Statement, Seller and its accountants will,
at Seller’s expense, be permitted reasonable access to review the financial books and records of the Business, to the extent
related to the Proposed Final Closing Purchase Price, during regular business hours and such other good faith, reasonable cooperation
from Buyer and its personnel, accounts and advisors as it may reasonably request to enable it to review and evaluate Buyer’s
determination of the Proposed Final Closing Purchase Price Statement.


 


(c)          If Seller does not
deliver a written notice of dispute setting forth in reasonable detail the items and amounts in dispute (a “Dispute Notice”)
to Buyer within 30 days after receiving the Proposed Final Closing Purchase Price Statement, the Parties agree that the Proposed
Final Closing Purchase Price Statement will become final, binding and conclusive upon the Parties. If Seller delivers a Dispute
Notice to Buyer (the items and amounts in dispute, the “Disputed Items”) within such 30-day period, the Parties
will negotiate in good faith to resolve the Disputed Items during the 30-day period commencing on the date Buyer receives such
Dispute Notice. If the Parties reach agreement with respect to all Disputed Items within such 30-day period, Buyer will revise
the Proposed Final Closing Purchase Price Statement to reflect such agreement, which will be final, binding and conclusive upon
the Parties. For the avoidance of doubt, any item or amount that is not specified as a Disputed Item in the Dispute Notice will
be deemed to be final, binding and conclusive upon the Parties from and after such time as the Dispute Notice is delivered. If
Seller and Buyer do not obtain a final resolution of all Disputed Items within such 30-day period, then the unresolved Disputed
Items (the “Unresolved Items”) will be submitted to an independent firm of certified public accounts selected
by Buyer and reasonably acceptable to Seller (the “Accounting Firm”). The Accounting Firm, acting as an expert
and not as arbitrators, will render a determination regarding the Unresolved Items within 30 days after referral of the matter
to the Accounting Firm, or as soon as practicable thereafter, which determination must be in accordance with the terms of this
Agreement and in writing and must set forth, in reasonable detail, the basis therefor. The determination of the Accounting Firm
will be final, conclusive and binding upon the Parties absent manifest error, and judgment may be entered upon the determination
of the Accounting Firm in any court having jurisdiction over the Party against which such determination is to be enforced.


 






    	 	 -22-	 



     


    

 


(d)          The Accounting Firm
will make a determination only with respect to the Unresolved Items, and in a manner consistent with this the provisions of this
Agreement, and in no event will the Accounting Firm’s determination of Unresolved Items be for an amount outside the range
of disagreement between Buyer and Seller. Each Party will use its commercially reasonable efforts to furnish to the Accounting
Firm such work papers and other documents and information pertaining to the Unresolved Items as the Accounting Firm may request.


 


(e)          Buyer will revise
the Proposed Final Closing Purchase Price Statement to reflect the determination of the Accounting Firm pursuant to this Section
2.7(e). The “Final Closing Purchase Price” will mean the Proposed Final Closing Purchase Price as finally
revised pursuant to this Section 2.7.


 


(f)          The fees and expenses
of the Accounting Firm will be borne in the same proportion as the aggregate dollar amount of the Unresolved Items that are unsuccessfully
disputed by each party (as finally determined by the Accounting Firm) bears to the aggregate dollar amount of all of the Unresolved
Items submitted to the Accounting Firm.


 


(g)          No later than three
Business Days after the date on which the Final Closing Purchase Price is finally determined pursuant to this Section 2.7:


 


(i)          if the Final
Closing Purchase Price is equal to or exceeds the Estimated Closing Purchase Price, Buyer will pay Seller the amount by which the
Final Closing Purchase Price exceeds the Estimated Closing Purchase Price (if any) by wire transfer of immediately available funds,
pursuant to instructions delivered to Buyer by Seller; and


 


(ii)          if the
Estimated Closing Purchase Price exceeds the Final Closing Purchase Price, Seller will pay Buyer an amount equal to the difference
between the Estimated Closing Purchase Price minus the Final Closing Purchase Price (if any) by wire transfer of immediately available
funds, pursuant to instructions delivered to Seller by Buyer.


 


(h)          Any payments made
pursuant to this Section 2.7 will be treated as an adjustment to the Closing Purchase Price, including for Tax purposes,
except as otherwise required by any Legal Requirement.


 


Section 2.8          Closing.
Upon the terms and subject to the conditions of this Agreement, the closing of the transactions contemplated hereby (the “Closing”)
will take place at the offices of Jones Day, 325 John H. McConnell Boulevard, Columbus, Ohio 43215, at 10:00 A.M. on the third
Business Day following the satisfaction or waiver of the conditions set forth in Article VI (other than those conditions
that by their terms cannot be satisfied until the Closing, but subject to the fulfillment or waiver of such conditions at the Closing),
or on such date and time as the Parties mutually agree in writing. The time and date of the Closing is herein called the “Closing
Date.” The Closing will be held by the remote exchange of documents unless another method or place is agreed to in writing
by the Parties.

Section 2.10       Earnout
Payments.


 


(a)          Contingent Payments.
Subject to Buyer’s right to off-set the Earnout Payments as set forth in this Agreement, during the Contingent Payment Period,
Buyer will pay to Seller an amount equal to eight percent of the Annual Sales for each Measuring Year (the “Contingent
Payments”). In the case of Contingent Payments to be made with respect to the first three Measuring Years during the
Contingent Payment Period, Buyer will make such payments on a quarterly basis (equal to the greater of (i) eight percent of Net
Sales during the applicable fiscal quarter or (ii) $1,675,000) to Seller, by wire transfer of immediately available funds to such
account as directed by Seller, within 30 days following the end of each fiscal quarter during the applicable Measuring Year. Notwithstanding
the foregoing, with respect to the first Measuring Year, the minimum Contingent Payment will be pro rated based on a fraction,
the numerator of which equals the number of days elapsed between the Closing Date through and including June 30, 2017 and the denominator
of which equals 365, and, to the extent such pro ration results in Seller receiving less than the minimum Contingent Payment for
such first Measuring Year, Buyer will pay Seller an amount equal to the difference between what the Seller received and the minimum
Contingent Payment for such first Measuring Year within 30 days following the end of the second fiscal quarter of the fourth Measuring
Year (such payment, the “Catch-up Contingent Payment”). Notwithstanding the foregoing, if the Contingent Payment
in any of the first three Measuring Years would be less than $6,700,000 (as pro rated for the first Measuring Year) based
upon the calculation of Net Sales set forth above, then the Contingent Payment for the applicable Measuring Year will be deemed
to be $6,700,000 (as pro rated for the first Measuring Year) (each such Contingent Payment during the first three Measuring
Years, and the Catch-up Contingent Payment, each a “Guaranteed Payment”); provided, however, that
Buyer will have the right to off-set the difference between $6,700,000 and the amount that would have otherwise been payable in
the absence of this minimum threshold against any future Earnout Payments that are not Guaranteed Payments. In no event will the
sum of all Contingent Payments made hereunder exceed $160,000,000.


 






    	 	 -25-	 



     


    

 


(b)          Milestone Payments.


 


(i)          Subject
to Buyer’s right to off-set the Earnout Payments as set forth in this Agreement, following the Closing but only during the
Contingent Payment Period, Buyer will pay to Seller the following additional amounts (each, a “Milestone Payment”)
upon the achievement by or on behalf of Buyer of the following events (each, a “Milestone Event”):


 


(A)          $10,000,000,
payable after the first Fiscal Year in which Annual Sales exceed $100,000,000;


 


B)          $15,000,000,
payable after the first Fiscal Year in which Annual Sales exceed $200,000,000;


 


(C)          $20,000,000,
payable after the first Fiscal Year in which Annual Sales exceed $300,000,000; and


 


(D)          $25,000,000,
payable after the first Fiscal Year in which Annual Sales exceed $400,000,000.


 


(ii)         For the
avoidance of doubt, each Milestone Payment will be paid only once, and therefore in no event will the Milestone Payments exceed
$70,000,000 in the aggregate; provided, however, that more than one Milestone Payment can be earned in the same Fiscal
Year. For the sake of clarity, a Milestone Payment is not a Contingent Payment, and a Contingent Payment is not a Milestone Payment.


 


(iii)        Within
45 days following the end of each Fiscal Year in which a Milestone Event has been achieved, Buyer will pay to Seller, by wire transfer
of immediately available funds to such account as directed by Seller, an amount equal to the applicable Milestone Payment.


 


(c)          Notwithstanding anything
to the contrary in this Agreement and subject to the qualifications set forth in Article VIII, the obligation of Buyer to
make the Earnout Payment will be qualified in its entirety by the right of Buyer to reduce the amount of the Earnout Payment by
the amount of (i) any payment that Seller may be required to make to Buyer pursuant to Section 2.7(g)(ii) or (ii) certain
indemnifiable Losses in respect of one or more indemnification claims to which any Buyer Indemnitee is entitled pursuant to Article
VIII.


 


(d)          From and after the
Closing, Buyer may operate the Business, Acquired Assets and Assumed Liabilities as it deems appropriate in its sole discretion,
even if those operations adversely affect the potential for Seller to receive any Earnout Payments, including changing the price,
marketing strategy, distribution channel or manufacturing, packaging or testing arrangements with respect to the Business Product.


 






    	 	 -26-	 



     


    

 


(e)          The Earnout Payments
made pursuant to this ‎Section 2.10 shall be treated as additional Purchase Price, including for Tax purposes, except
as otherwise required by any Legal Requirement.


 


(f)          Seller’s
Review of Earnout Payments.


 


(i)          On or prior
to the date of each Earnout Payment, Buyer shall deliver to Seller a reasonably detailed accounting of (i) the calculation of such
Earnout Payment and the Annual Sales for the Contingent Payment Period to which such Earnout Payment applies, if applicable, and
(ii) the aggregate amount of Net Sales during the entire Contingent Payment Period as of the date of such Earnout Payment, if applicable
(each, an “Earnout Payment Statement”); provided that Buyer shall only be required to deliver to Seller
an Earnout Payment Statement on account of Contingent Payments for the Fiscal Years ended June 30 of the first three Measuring
Years, and for no quarterly Contingent Payments made during such Measuring Years, and such annual Earnout Payment Statements shall
provide a calculation of the Contingent Payments and Annual Sales made in each fiscal quarter of such Measuring Year. During the
30-day period following Seller’s receipt of each Earnout Payment Statement, Seller and its accountants will, at Seller’s
expense, be permitted reasonable access to review the financial books and records of the Business, to the extent related to Annual
Sales of the Business that are subject to the Earnout Payment Statement, during regular business hours and such other good faith,
reasonable cooperation from Buyer and its personnel, accounts and advisors as it may reasonably request to enable it to review
and evaluate the Earnout Payment Statement. Seller shall have 30 days from the date of receipt of each Earnout Payment Statement
(such period, the “Earnout Payment Dispute Period”) to notify Buyer (such notice, the “Earnout Payment
Dispute Notice”), that Seller disagrees with the amount of the Earnout Payment subject to, or any items set forth in,
such Earnout Payment Statement. The Earnout Payment Dispute Notice shall set forth in good faith and reasonable detail Seller’s
disputed items and amounts. If Seller does not deliver an Earnout Payment Dispute Notice to Buyer during the Earnout Payment Dispute
Period, then the contents of the Earnout Payment Statement and the amount of the Earnout Payment to which such Earnout Payment
Statement applies shall be deemed to be final, binding and conclusive upon the Parties.


 


(ii)         If Seller
delivers an Earnout Payment Dispute Notice to Buyer (the items and amounts in dispute, the “Earnout Disputed Items”)
within such 30-day period, the Parties will negotiate in good faith to resolve the Earnout Disputed Items during the 30-day period
commencing on the date Buyer receives such Earnout Dispute Notice. If the Parties reach agreement with respect to all Earnout Disputed
Items within such 30-day period, Buyer will revise the Earnout Payment Statement to reflect such agreement, which will be final,
binding and conclusive upon the Parties. For the avoidance of doubt, any item or amount that is not specified as an Earnout Disputed
Item in the Earnout Dispute Notice will be deemed to be final, binding and conclusive upon the Parties from and after such time
as the Earnout Dispute Notice is delivered. If Seller and Buyer do not obtain a final resolution of all Earnout Disputed Items
within such 30-day period, then the unresolved Earnout Disputed Items (the “Unresolved Earnout Items”) will
be submitted to the Accounting Firm. The Accounting Firm, acting as an expert and not as arbitrators, will render a determination
regarding the Unresolved Earnout Items within 30 days after referral of the matter to the Accounting Firm, or as soon as practicable
thereafter, which determination must be in accordance with the terms of this Agreement and in writing and must set forth, in reasonable
detail, the basis therefor. The determination of the Accounting Firm will be final, conclusive and binding upon the Parties absent
manifest error, and judgment may be entered upon the determination of the Accounting Firm in any court having jurisdiction over
the Party against which such determination is to be enforced.


 






    	 	 -27-	 



     


    

 


(iii)        The Accounting
Firm will make a determination only with respect to the Unresolved Earnout Items, and in a manner consistent with this the provisions
of this Agreement, and in no event will the Accounting Firm’s determination of Unresolved Earnout Items be for an amount
outside the range of disagreement between Buyer and Seller. Each Party will use its commercially reasonable efforts to furnish
to the Accounting Firm such work papers and other documents and information pertaining to the Unresolved Earnout Items as the Accounting
Firm may request.


 


(iv)        The fees
and expenses of the Accounting Firm will be borne in the same proportion as the aggregate dollar amount of the Unresolved Earnout
Items that are unsuccessfully disputed by each party (as finally determined by the Accounting Firm) bears to the aggregate dollar
amount of all of the Unresolved Earnout Items submitted to the Accounting Firm.


 


(v)        No later
than three Business Days after the date on which the final Earnout Payment Statement is finally determined pursuant to this Section
2.10(f), Buyer will pay Seller any additional amounts required to be paid as part of the Earnout Payment subject to the final
Earnout Payment Statement by wire transfer of immediately available funds, pursuant to instructions delivered to Buyer by Seller.


 


Section 2.11       Withholding.
Buyer, Seller or their respective Affiliates may deduct and withhold from the consideration payable in connection with the transactions
contemplated by this Agreement or any other Transaction Document such amounts as Buyer, Seller or any of their respective Affiliates
or agents, as applicable, is required to deduct and withhold with respect to the making of such payment under any Legal Requirement
related to Taxes. Any amounts deducted and withheld in accordance with this Section 2.11 will be treated for all purposes
of this Agreement and any other Transaction Document, as applicable, as having been paid to the Person in respect of which such
deduction and withholding was made.

ARTICLE
III

REPRESENTATIONS AND WARRANTIES OF SELLER


 


Except as set forth in the Disclosure Schedules,
Seller hereby represents and warrants to Buyer as follows and, unless the context otherwise requires, each reference to “Seller”
in this Article III will also refer to each of Seller’s Subsidiaries:


 


Section 3.1         Organization.
Seller is a corporation duly organized, validly existing and in good standing under the Legal Requirements of the State of Delaware
and has all requisite corporate power and authority to own and lease the Acquired Assets and to operate and carry on the Business
as presently conducted. Seller is duly qualified to do business as a foreign corporation or limited liability company, as applicable,
and is in good standing in each jurisdiction wherein the nature of the Business or the ownership of the Acquired Assets makes such
qualification necessary, except where the failure to be so qualified and in good standing would not, individually or in the aggregate,
reasonably be expected to be materially adverse to Seller or the Business.


 


Section 3.2        Authority,
Validity and Enforceability. Subject to obtaining the Stockholder Approval, Seller has all requisite power and authority
or capacity, as applicable, to execute, deliver and perform its respective obligations under this Agreement and the other Transaction
Documents. This Agreement and each of the other Transaction Documents have been duly executed and delivered by Seller and, assuming
due authorization, execution, delivery and performance by Buyer, represent the legal, valid and binding obligation of Seller enforceable
against Seller in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium, liquidation,
fraudulent conveyance and other similar Legal Requirements and principles of equity affecting creditors’ rights and remedies
generally (the “General Enforceability Exceptions”). Subject to obtaining the Stockholder Approval, no further
action on the part of Seller is or will be required in connection with the transactions contemplated by this Agreement or the other
Transaction Documents.


 


Section 3.3         No Subsidiaries.
Seller has no Subsidiaries other than those set forth on Schedule 3.3.


 


Section 3.4         No Conflict.
Subject to and assuming satisfaction of the requirements set forth in ‎Section
3.5, neither the execution of this Agreement or the other Transaction Documents, nor the performance by Seller of Seller’s
obligations under any Transaction Document will (a) violate or conflict with any Legal Requirement applicable to Seller or
by which Seller’s properties or assets are bound, (b) contravene any provision contained in the Organizational Documents
of Seller, (c) conflict with, violate or result in a breach (with or without the lapse of time, the giving of notice or both) of,
or constitute a default (with or without the lapse of time, the giving of notice or both) or result in the creation of any Lien
under (i) any Contract or (ii) any Legal Requirement or other restriction of any Governmental Authority to which Seller is bound
or to which the Equity Interests of Seller or any of its assets or properties are subject, or (d) result in the acceleration of,
or permit any Person to terminate, modify, cancel, accelerate or declare due and payable prior to its stated maturity, any material
obligation of Seller, which in the case of clauses (c) and (d) above, would not, individually or in the aggregate,
reasonably be expected to either be materially adverse to the Business or materially affect the ability of Seller to timely consummate
the transactions contemplated by this Agreement.


 






    	 	 -29-	 



     


    

 


Section 3.5        Consents.
Except as provided in Section 3.2, notice to, filing with, or authorization, registration, consent or approval of any Person
or any Governmental Authority is necessary for the execution, delivery or performance of this Agreement or the other Transaction
Documents to which Seller is a party or the consummation of the transactions contemplated by any Transaction Document by Seller,
except for (a) compliance with, and any filings required by, the HSR Act, and (b) notices, filings and approvals set forth
on Schedule ‎3.5.


 


Section 3.6         Financial
Statements; Undisclosed Liabilities.


 


(a)          Since December 31,
2012, Seller has filed with or otherwise furnished to (as applicable) the SEC all registration statements, prospectuses, forms,
reports, definitive proxy statements, schedules and documents required to be filed or furnished by it under the Securities Act
or the Exchange Act, as the case may be, together with all certifications required pursuant to the Sarbanes-Oxley Act of 2002,
as amended (“Sarbanes-Oxley Act”) (such documents and any other documents filed by Seller with the SEC, as have
been supplemented, modified or amended since the time of filing, collectively, the “Seller SEC Documents”),
except as would not, individually or in the aggregate, reasonably be expected to be materially adverse to the Business. As of their
respective filing dates or, if supplemented, modified or amended since the time of filing and prior to the date hereof, as of the
date of the most recent such supplement, modification or amendment, the Seller SEC Documents (i) did not contain any untrue statement
of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements
made therein, in light of the circumstances under which they were made, not misleading, except as would not, individually or in
the aggregate, reasonably be expected to be materially adverse to the Business, and (ii) complied with the then applicable requirements

such Owned Business Intellectual Property set forth in Schedule 3.15(b)(i).

the SEC with respect to such preliminary Proxy Statement and shall cause a definitive Proxy Statement and all required amendments
and supplements thereto to be disseminated to the Seller Stockholders entitled to vote at the Stockholders’ Meeting at the
earliest practicable time. Seller will notify Buyer promptly of the receipt of, and will respond promptly to, any (A) comments
from the SEC or its staff and (B) requests by the SEC or its staff for amendments or supplements to the Proxy Statement or for

provided, each of the Parties will use its commercially reasonable efforts to take, or cause to be taken, all action, and to do,
or cause to be done, all things reasonably necessary, proper or advisable under applicable Legal Requirements to consummate and
make effective the transactions contemplated by this Agreement. Each of the Parties will use its commercially reasonable efforts
to promptly obtain all authorizations, consents, orders and approvals of, and to promptly give all notices to and make all filings
with, all Governmental Authorities and other Persons that may be or become necessary for the performance of its obligations under
this Agreement and the consummation of the transactions contemplated by this Agreement, including the consents, waivers, approvals
and notices referred to in Schedule ‎3.5. All such consents, waivers, approvals and notices shall be in writing and
in form and substance reasonably satisfactory to Buyer. Executed counterparts of such consents, waivers and approvals shall be
delivered to Buyer promptly after receipt thereof, and copies of such notices shall be delivered to Buyer promptly after the making

authorizations, consents, orders and approvals from third parties that are not Governmental Authorities, no Party will be required
to make payments to any Person, provided, that Seller will remain required to make payments required by the terms of any
Contract between Seller and such Person.


 


(b)          In furtherance and
not in limitation of the terms of Section 5.4(a), to the extent not made prior to the date hereof, each Party will make,

later than the fifth Business Day after the date hereof, and will supply as promptly as practicable to the appropriate Governmental
Authorities any additional information and documentary material that may be requested pursuant to the HSR Act or the FTC Order.
The Parties agree that they will request early termination of the waiting period under the HSR Act (to the extent any filings thereunder
are required by Legal Requirements) and the FTC Order. Without limitation of the foregoing, neither the Parties nor its Affiliates
will enter into any Contract with any Governmental Authority not to consummate the transactions contemplated by this Agreement,
except with the prior written consent of the other Party. Notwithstanding anything herein to the contrary, neither Buyer nor any
of its Affiliates will be under any obligation to, nor, without Buyer’s prior written consent (which consent may be withheld
in Buyer’s sole discretion), will Seller propose, negotiate, offer to commit and effect (and if such offer is accepted, commit
to and effect), by consent decree, hold separate Order, or otherwise, or agree to any consent decree, hold separate Order or other
Order providing for, (i) the sale, divestiture or disposition of any assets or businesses of Buyer or any of its Affiliates or
Seller, or the holding separate of any capital stock of any such Person, or the imposition of any limitation on the ability of
Buyer or any of its Affiliates, to own such assets, or (ii) the imposition of any other limitation whatsoever on the business activities
of Buyer or any of its Affiliates or Seller. Each Party will be responsible for and pay when due its costs, fees and expenses in
connection with any filings or other actions of the Parties called for herein and necessitated by the HSR Act, the FTC Order or
any similar antitrust or competition Legal Requirements applicable to the Parties with respect to the transactions contemplated
by this Agreement.

promptly notify the others of any written communication to that Party from any Governmental Authority and, subject to applicable
Legal Requirement, permit the other to review in advance any proposed written communication to any of the foregoing and (ii) furnish
the other with copies of all correspondence, filings and communications (and memoranda setting forth the substance thereof) between
them and its Affiliates on the one hand, and any Governmental Authority on the other hand, with respect to this Agreement and the
transactions contemplated hereby.


 


(d)          Subject to the provisions
of this Section 5.4, in the event any Action is commenced which questions the validity or legality of the transactions contemplated
by this Agreement or seeks damages in connection therewith, the Parties agree to cooperate and use their commercially reasonable
efforts to defend against such Action and, if an Order is issued in any such Action, to use commercially reasonable efforts to
have such Order lifted, and to cooperate reasonably regarding any other impediment to the consummation of the transactions contemplated
by this Agreement.


 


(e)          Each Party will give
prompt written notice to the other of the occurrence, or failure to occur, of any event which occurrence or failure would cause
any representation or warranty of Seller or Buyer as the case may be, contained in the Transaction Documents to be untrue or inaccurate
in any material respect at any time from the date hereof to the Closing or that would reasonably be expected to result in the failure
to satisfy any of the conditions specified in Article VI, or otherwise prohibit, condition or delay the Closing. Notwithstanding
anything herein to the contrary, in no event will any notice provided under this Section 5.4(e) be deemed to cure any breach
of any such representation or warranty for any purpose under this Agreement.


 


Section 5.5         Public
Announcements. The timing and content of all public announcements regarding any aspect of this Agreement or the transactions
contemplated hereby will be mutually agreed upon in advance by the Parties; provided that any Party may make any such announcement
or disclosure which it in good faith believes, based on advice of counsel, is required by Legal Requirement or securities listing
standard (in which case each party will consult with the other prior to any such announcement or disclosure to the extent reasonably
practicable as to the form and content of such disclosure or announcement and will only disclose that information that is required
by Legal Requirement based upon advice of counsel).

or any other member of the Controlled Group who do not become Transferred Employees and “qualified beneficiaries” of
such employees for whom a “qualifying event” occurs after Closing Date. Buyer will have the sole responsibility for
“continuation coverage” benefits provided after the Closing Date for all Transferred Employees and “qualified
beneficiaries” of Transferred Employees for whom a “qualifying event” occurs after the Closing Date. The terms
“continuation coverage,” “qualified beneficiaries” and “qualifying event” shall have the meanings
ascribed to them under section 4980B of the Code and sections 601-608 of ERISA and any similar state Legal Requiement.


 


(f)          Following the date
of this Agreement, Seller will reasonably cooperate in all matters reasonably necessary to effect the transactions contemplated
by this Section 5.6, including, to the extent permitted by applicable Legal Requirement, exchanging information and data
relating to payroll, workers compensation, employee benefits and employee benefit plan coverages, and in obtaining any governmental
approvals required hereunder.

(g)          This Agreement is not intended by the Parties
to, and nothing in this Section 5.6 or otherwise in this Agreement, whether express or implied, will (i) constitute
an amendment to any Employee Plan or any employee benefit plan of Buyer or its Affiliates or (ii) confer on any current or former
employee of Seller or any other Person (other than the parties to this Agreement) any rights or remedies (including third-party
beneficiary rights).


 


Section 5.7         Exclusivity.


 


(a)          Acquisition Proposal.
Except as may be permitted by Section 5.7(b), Seller shall, and shall cause its Subsidiaries and Representatives to, immediately
cease and cause to be terminated all existing activities, discussions or negotiations with any Persons (other than Buyer) conducted
heretofore or that may be on-going with respect to, or that would reasonably be expected to lead to, any Acquisition Proposal.
From and after the date of this Agreement until the earlier of Closing or the termination of this Agreement in accordance with
Article VII, Seller shall not, shall cause its Subsidiaries not to, and shall direct their respective Representatives not
to, directly or indirectly, (i) initiate, facilitate, solicit or encourage (including by way of furnishing non-public information),
directly or indirectly, inquiries or proposals that constitute, or could reasonably be expected to lead to, any Acquisition Proposal,
(ii) initiate, engage or participate in any way with any third party in any discussions or negotiations regarding, or furnish or
disclose any non-public information to any third party in connection with, or take any other action to knowingly facilitate any
inquiries or the making of any proposal that constitutes, or could reasonably be expected to lead to, any Acquisition Proposal
(except to notify such third party of the existence of the provisions of this Section 5.7), or (iii) except as permitted
pursuant to Section 5.7(e) below, enter into any Acquisition Agreement or approve or resolve to approve any Acquisition
Proposal, or enter into any agreement, arrangement or understanding that would require Seller to abandon, terminate or fail to
consummate the transactions contemplated by this Agreement. Without limiting the foregoing,
it is agreed that any violation of the foregoing restrictions by any Representative, whether or not such Person is purporting to
act on behalf of Seller or any of its Subsidiaries, or otherwise, will be deemed to be a breach of this Section 5.7 by Seller,
and Seller will cause its Representatives to comply with the terms of this Section 5.7.


 


(b)          Notwithstanding the
restrictions set forth in Section 5.7(a), at any time prior to obtaining Stockholder Approval, in response to an unsolicited
bona fide written Acquisition Proposal that the Seller Board determines in good faith (after consultation with outside counsel
and its financial advisor) constitutes or would reasonably be expected to lead to a Superior Proposal, and which Acquisition Proposal
did not otherwise result from a breach of Section 5.7(a), Seller may, if and only to the extent that the Seller Board determines
in good faith (after consultation with outside legal counsel) that failure to do so would be reasonably likely to be a violation
of its fiduciary duties to the Seller Stockholders under applicable Delaware Legal Requirements, and subject to compliance with
Section 5.7(e), (i) contact the Person making such Acquisition Proposal (and its Representatives) solely to clarify the
terms and conditions thereof, (ii) furnish non-public information with respect to Seller and its Subsidiaries to the Person making
such Acquisition Proposal (and its Representatives) pursuant to a customary confidentiality agreement not less restrictive of such
Person than the Confidentiality Agreement; provided, however, that all such information has previously been provided
to Buyer or is provided to Buyer prior to or substantially concurrent with the time it is provided to such Person, and (iii) participate
in discussions or negotiations with the Person making such Acquisition Proposal (and its Representatives) regarding such Acquisition
Proposal.


 






    	 	 -51-	 



     


    

 


(c)          Notice of Acquisition
Proposal. From and after the date of this Agreement until the earlier of Closing or the termination of this Agreement, Seller
shall promptly (and in any event within one calendar day following and three Business Days prior to providing any such Person with
any information) notify Buyer in the event that Seller receives, directly or indirectly: (i) any Acquisition Proposal; (ii) any
request for non-public information relating to Seller or its Subsidiaries by any Person that informs Seller, its Subsidiaries or
its Representatives that such Person is considering making, or has made, an Acquisition Proposal; or (iii) any request for discussions
or negotiations relating to a possible Acquisition Proposal. Such notice shall be made orally and confirmed in writing, and shall
indicate the material terms and conditions thereof and the identity of the other party or parties involved. Seller will (A) promptly
keep Buyer reasonably apprised of any material developments, discussions and negotiations with respect to such Acquisition Proposal
or inquiry, as well as any material modification of or amendment thereto, (B) promptly upon receipt or delivery thereof, provide
Buyer with copies of all drafts and versions of agreements (including schedules and exhibits) and other material documentation
or correspondence relating to any Acquisition Proposal exchanged between Seller and such Person or their respective Representatives,
and (C) promptly make available to Buyer any non-public information of Seller and its Subsidiaries furnished to any third party
in connection therewith that has not previously been provided to Buyer.


 


(d)          Nothing contained
in this Section 5.7 prohibits or will be construed as prohibiting Seller or the Seller Board from (i) complying with its
disclosure obligations under federal or state Legal Requirements with regard to an Acquisition Proposal, including but not limited
to taking and disclosing to Seller Stockholders a position contemplated by Rule 14D-9 or Rule 14e-2(a) promulgated under the Exchange
Act or (ii) making any disclosure to Seller Stockholders if, in the good faith judgment of the Seller Board, after consultation
with outside legal counsel, failure to make such disclosure would be inconsistent with applicable Legal Requirements; provided,
however, a Seller Adverse Recommendation Change (as defined below) shall only be made in accordance with Section 5.7(e).


 






    	 	 -52-	 



     


    

 


(e)          Actions by Seller.
Neither the Seller Board nor any committee thereof shall (i) approve or recommend, or propose publicly to approve or recommend,
any Acquisition Proposal, or cause or permit Seller or its Subsidiaries to execute or enter into any letter of intent, memorandum
of understanding, agreement in principle, merger agreement, acquisition agreement, joint venture agreement, partnership agreement
or similar agreement constituting or related to, or that is intended to or could reasonably be expected to lead to, any Acquisition
Proposal (other than a confidentiality agreement referred to in Section 5.7(b)) (an “Acquisition Agreement”),
or (ii)(A) withdraw, amend or modify in a manner adverse to Buyer, or publicly propose to withdraw, amend or modify in a manner
adverse to Buyer, the Seller Board Recommendation or (B) recommend, adopt or approve, or propose publicly to recommend adopt or
approve, or fail to reject, any Acquisition Proposal (any action described in this clause (ii) being referred to as a “Seller
Adverse Recommendation Change”). Notwithstanding the foregoing, if, prior to obtaining Stockholder Approval, the
Seller Board determines in good faith that failure to do so would be reasonably likely to be a violation of its fiduciary duties
to the Seller Stockholders under applicable Delaware Legal Requirements, Seller may (A) terminate this Agreement pursuant to Section
7.1(h) and cause Seller to enter into an Acquisition Agreement with respect to a Superior Proposal (which was made after the
date hereof and did not otherwise result from a breach of this Section 5.7) or (B) following an Intervening Event, make
a Seller Adverse Recommendation Change, if, in either case: (x) Seller provides written notice (a “Notice of Adverse Recommendation”)
advising Buyer that the Seller Board intends to take such action and specifying the reasons therefor, including, if applicable,
the material terms and conditions of any Superior Proposal that is the basis of the proposed action by the Seller Board (it being
understood and agreed that any amendment to the amount of consideration or any other material term of such Superior Proposal shall
require a new Notice of Adverse Recommendation); (y) for a period of five Business Days following Buyer’s receipt of a Notice
of Adverse Recommendation (or a period of two Business Days in the case of a new Notice of Adverse Recommendation following an
amendment to the amount of consideration or any other material term of a Superior Proposal that is the subject of a previously
provided Notice of Adverse Recommendation), Seller negotiates with Buyer in good faith to make such adjustments to the terms and
conditions of this Agreement as would enable Seller to proceed with its recommendation of this Agreement and the transactions contemplated
hereby and not make such Seller Adverse Recommendation Change; and (z) if applicable, at the end of such five Business Day period,
the Seller Board continues to believe that the Acquisition Proposal, if any, constitutes a Superior Proposal (after taking into
account such adjustments to the terms and conditions of this Agreement).


 


(f)          Seller shall not release
nor permit the release of any Person from, or waive or permit the waiver of any provision of, and Seller shall use its reasonable
efforts to enforce or cause to be enforced, any confidentiality, “standstill” or similar agreement to which any of
Seller or any of its Subsidiaries is a party, unless the Seller Board determines in good faith (after consultation with outside
legal counsel) that the failure to take such action would be a breach of its fiduciary duties to Seller Stockholders under applicable
Legal Requirement; provided, however, that Seller shall provide to Buyer at least four Business Days’ prior
written notice of such upcoming release and/or waiver and specifying the reasons therefor in reasonable detail, including the identities
of the parties to such confidentiality, “standstill” or similar agreements; provided, further, however,
that Seller shall not release or permit the release from, or waive or permit the waiver of, any provision of any standstill or
similar agreement the effect of which would be to permit such Person to effect a transaction without the approval of Seller Board.


 


(g)          Immediately following
the execution of this Agreement, Seller shall request each Person which has heretofore executed a confidentiality agreement in
connection with such Person’s consideration of acquiring Seller or the Business to return or destroy all confidential information
heretofore furnished to such Person by or on Seller’s behalf.

Section 5.8         Non-Disclosure;
Non-Solicitation; Non-Disparagement. 


 


(a)          Confidential Information.
Seller recognizes that, due to the nature of its relationship with the Business, Seller and its Affiliates have had, and will have
access to, and have developed, confidential business information, proprietary information, and trade secrets relating to the Business.
Seller acknowledges that such information is valuable to the Business, and that disclosure to, or use for the benefit of, any Person
could cause substantial damage the Business. In recognition that the goodwill and business relationships described herein are Acquired
Assets and that loss of or damage to those relationships would destroy or diminish the value of the Business, Seller will, and
will cause its Affiliates and Representatives to, at all times maintain the confidentiality of Confidential Information, and Seller
will not, and will cause its Affiliates and Representatives to, disclose any such information to any Person, nor will Seller or
its Affiliates or Representatives use any Confidential Information for any purpose. Seller’s duty of confidentiality with
regard to Confidential Information will not extend to: (i) any information that, at the time of disclosure, had been previously
published and was part of the public domain; or (ii) information that is published after disclosure, unless such publication
is a breach of this Agreement by such Person or any other obligation of confidentiality.


 


(b)          Non-Competition.
As a material inducement to Buyer to enter into this Agreement, for a period of five years from the Closing Date, Seller will not,
directly or indirectly, for itself or any other Person (either as principal, agent, manager, consultant, partner, owner, investor,
employee, distributor, dealer, representative, joint venturer, creditor, franchisee or otherwise), engage in any business that
competes with the Business in the Territory, including: (i) developing, manufacturing, marketing, selling or distributing any product
that accumulates in lymphatic tissue or tumor-draining lymph nodes for the purpose of (A) lymphatic mapping or (B) identifying
the existence, location or staging of cancer in a body; (ii) developing, manufacturing, marketing, selling or distributing any
product that provides for or facilitates any test or procedure that is reasonably substitutable for any test or procedure provided
for or facilitated by the Business Product; or (iii) marketing any products for unapproved uses that allow such products to compete
with the Business Product; in each case, regardless of whether Seller utilizes any Business Intellectual Property Rights; provided,
however, that Seller’s actions that relate to obtaining the approval of Governmental Authorities in order to sell
products outside of the Territory that may compete with the Business shall not violate the provisions hereof so long as (x) such
products are, at the time of development and approval, solely intended to be marketed, sold or distributed outside of the Territory,
(y) such products are not developed in breach of the License-Back Agreement, and (z) no marketing or commercialization of such
products to the public occurs within five years from the Closing Date.


 


(c)          Non-Solicitation.
For a period of five years from the Closing Date, Seller will not, either directly or indirectly (individually, or through or on
behalf of another Person, as owner, partner, agent, employee, consultant, or in any other capacity), engage in any of the following
activities: (i) hire, solicit, encourage, or engage in any activity or otherwise attempt to induce any Transferred Employee or
other then-current employee of the Business in the Territory, to terminate his or her employment or relationship with Buyer or
its Affiliates, (ii) in any way interfere with the relationship between Buyer or its Affiliates and any employee of the Business,
including Transferred Employees, or (iii) induce or attempt to induce any customer, supplier, licensee, or business relation of
the Business to cease doing business with Buyer or its Affiliates in the Territory or in any way interfere with the relationship
between any customer, supplier, licensee or business relation of the Business. Notwithstanding anything else to the contrary contained
in this paragraph, Seller shall be permitted to solicit and hire any former employee of the Business that is involuntarily terminated
from his or her employment with Buyer or its Affiliates; provided, however, that such employment of any former employee
may not be for purposes that are of would be in violation of Sections 5.8(a) and (b).


 






    	 	 -54-	 



     


    

 


(d)          Nondisparagement.
No Party will at any time disparage in any material respect another Party or any of such other Party’s Representatives, or
the reputation of any of the foregoing Persons of the businesses of any of them.


 


(e)          Off-label Uses.
Each Party shall use its good faith, commercially reasonable efforts to ensure that all labeling with respect to the products manufactured
by or for the benefit of Buyer or Seller, as applicable, for a period of five years from the Closing Date shall not suggest that
users thereof may use such products in any manner (such as promoting “off-label” use) that would violate the restrictions
of such Party set forth in Section 5.8(b) or the License-Back Agreement.


 


(f)          Enforcement.
If, at the time of enforcement of the covenants contained in this Section 5.8 (the “Restrictive Covenants”),
a Governmental Authority holds that the duration, scope or area restrictions stated herein are unreasonable under the circumstances
then existing, the Parties agree that the maximum enforceable duration, scope or area reasonable under such circumstances will
be substituted for the stated duration, scope or area and that the Governmental Authority will be allowed and directed to revise
the restrictions contained herein to cover such maximum period, scope and area permitted by applicable Legal Requirement. Each
Party has consulted with legal counsel regarding the Restrictive Covenants and based on such consultation has determined and hereby
acknowledges that the Restrictive Covenants are reasonable in terms of duration, scope and areas restrictions and are necessary
to protect, among other things, the goodwill of the Business and the substantial investment in the Business made by Buyer. Each
Party further agrees that it will not challenge the reasonableness of the duration, scope and area restrictions in any Action with
respect to the Restrictive Covenants, regardless of who initiates such Action.


 


(g)          Each Party acknowledges
that the other Party is entitled to an injunction, restraining Order or other equitable relief from any Governmental Authority
of competent jurisdiction in the event of any breach of the Restrictive Covenants without the necessity of proving actual Losses
or posting any bond. The rights and remedies provided by this Section 5.8 are cumulative and in addition to any other rights
and remedies that each Party may have hereunder or at law or in equity. Notwithstanding anything contained in this Agreement to
the contrary, if a Party breaches the Restrictive Covenants and the aggrieved Party seeks and obtains an injunction, restraining
Order or other equitable relief from any Governmental Authority of competent jurisdiction, the five-year period referred to in
this Section 5.8 will be computed from the date relief is granted to the aggrieved Party instead of from the Closing Date
and reduced by any time following the Closing Date during which such breaching Party complied with its obligations hereunder.

Section 5.9         Release;
Termination of Distribution Agreement.


 


(a)          Effective as of the
Closing, each Party hereby irrevocably waives, releases and discharges, and will cause each of their respective Affiliates not
to assert, to the fullest extent permitted by applicable Legal Requirement, any claims, or take or bring any Actions, against the
other Party or the Business, and each of their respective directors, officers, stockholders, members or managers, in relation to
any and all Actions, debts, accounts, bonds, bills, covenants, Contracts, controversies, agreements, Liabilities, executions, variances,
claims and other obligations of whatever kind or nature, in law, equity or otherwise, arising from, connected or related to, caused
by or based on any facts, conduct, activities, agreements, transactions, events or occurrences known or unknown, of any type that
existed, occurred, happened, arose or transpired from the beginning of time through the Closing Date.


 


(b)          Seller and Buyer hereby
agree that the Supply and Distribution Agreement, dated November 15, 2007, between Seller and Buyer (the “Supply and Distribution
Agreement”), will be terminated effective as of the Closing and that the provisions thereof shall be of no further force
and effect from and after the Closing. Seller and Buyer, on behalf of themselves and their Affiliates, irrevocably release and
forever discharge each other, effective as of the Closing, from all of their respective duties, obligations and Liabilities under
such Supply and Distribution Agreement (other than any indemnification, notification or data sharing obligations which shall survive
the termination).


 


(c)          Notwithstanding the
foregoing, nothing in this ‎Section 5.9 will (a) affect rights or obligations
under this Agreement or any other Transaction Document or (b) operate to release any payment or indemnification obligations, any
rights to indemnification, or any notification or data sharing obligations, in each case, that by their terms expressly survive
an termination of the Supply and Distribution Agreement.


 


Section 5.10       Tax
Matters.


 


(a)          Property Taxes (as
defined below) with respect to the Acquired Assets attributable to the taxable year of the Closing will be prorated as of the Closing
with Seller being liable for such Taxes attributable to the days in the taxable year through the Closing Date and Buyer being liable
for such Taxes attributable to days in the taxable year after the Closing Date. Proration of Property Taxes shall be made on the
basis of the most recent officially certified Tax valuation and assessment for the Acquired Assets. If such valuation pertains
to a taxable year or period other than that in which the Closing occurs, such proration shall be recalculated at such time as actual
Tax bills for such period are available and the parties shall cooperate with each other in all respects in connection with such
recalculation and pay any sums due in consequence thereof to the party entitled to recover the same within sixty days after the
issuance of such actual Tax bills. For purposes of this Section 5.10(a), “Property Taxes” means ad valorem
Taxes, property Taxes, general assessments and special assessments with respect to the Acquired Assets.


 


(b)          Seller shall bear
all Transfer Taxes incurred, imposed, assessed, or payable against Seller in connection with or as a result of this Agreement.
Each Party shall cooperate as reasonably requested to minimize such Transfer Taxes, including with respect to any available exemption
from such Transfer Taxes. Each Tax Return with respect to a Transfer Tax shall be prepared by the Party that customarily has primary
responsibility for filing such Tax Return pursuant to applicable Legal Requirements.


 






    	 	 -56-	 



     


    

 


(c)          Each Party will cooperate
fully, as and to the extent reasonably requested by the other Party, in connection with the preparation, execution and filing of
Tax Returns pursuant to this Section 5.10 and any Actions with respect to Taxes. Such cooperation will include the retention
and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such Tax
Returns and Actions and making employees available on a mutually convenient basis to provide additional information and explanation
of any material provided hereunder; provided, however, that in no event will Buyer be required to provide a copy
of any Tax Returns of Buyer or its Affiliates to any other Person. Seller agrees (i) to retain all books and records with
respect to Tax matters pertinent to the Acquired Assets or the Business relating to any taxable period beginning before the Closing
Date until three months following the expiration of the statute of limitations (and any extensions thereof) of the respective taxable
periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give Buyer reasonable
written notice prior to transferring, destroying or discarding any such books and records and, if Buyer so requests, Seller will
allow Buyer to take possession of such books and records.


 


(d)          As promptly as practicable
after the 30th Business Day following the determination of the Final Purchase Price pursuant to Section 2.7, Buyer will
deliver to Seller an allocation of the Purchase Price (and other applicable amounts for Tax purposes) among the Acquired Assets,
in accordance with Section 1060 of the Code and the Treasury Regulations thereunder (and any similar U.S. state or local Legal
Requirement) (the “Allocation”). Each Party will prepare and file, and cause his or its Affiliates to prepare
and file, all Tax Returns on a basis consistent with the Allocation (including IRS Form 8594 and any equivalent U.S. state or local
forms) and will take no position, and cause his or its Affiliates to take no position, inconsistent with the Allocation on any
Tax Return or in any audit or other Action with respect to Taxes or otherwise. In the event that the Allocation is disputed by
any Taxing Authority, the Party receiving notice of the dispute will promptly notify the other Party of such dispute, and each
Party agrees to use its commercially reasonable efforts to defend such Allocation in any audit or other Action and not to settle
or otherwise dispose of such audit or other Action without the prior written consent of the other Party (such consent not to be
unreasonably withheld, conditioned or delayed).


 


(e)          Notwithstanding anything
to the contrary in this Agreement, each Party will reimburse the other Party for any Taxes paid by such Party (or any of its Affiliates)
that are the responsibility of the other Party pursuant to this Agreement within ten Business Days after payment of such Taxes.


 


Section 5.11      Split
of Shared Contracts. The Contracts listed on Schedule 5.11 (the “Shared Contracts”) pertain partially
to the Business and partially to other business activities of Seller. Between the date of this Agreement and the Closing Date,
the Parties will use commercially reasonable efforts (or, with respect to any Contract designated with an asterisk on Schedule
5.11, Seller will use best efforts), and will continue those efforts after Closing, to obtain the consent of the other contract
parties to the Shared Contracts to split the Shared Contracts into two separate contracts, one covering the deliveries, services
or other performances pertaining to the Business and the other covering the deliveries, services or other performances pertaining
to the other business activities of Seller. Section 5.4(a) will apply mutatis mutandis with respect to obtaining
consent to split a Shared Contract.

Section 5.12      Transfer
of Certain Funds Received Post-Closing. With respect to any and all amounts received or collected by Seller from and after
the Closing (a) attributable to, or in respect of, any Acquired Asset or the Business (other than the Excluded Assets) and (b)
which become the property of Buyer as a result of the consummation of the transactions contemplated by this Agreement, Seller shall
provide notice of such receipt or collection to Buyer and pay promptly (and in any event within five Business Days of their receipt
or collection) to Buyer any and all such amounts so received or collected by wire transfer of immediately available funds to an
account specified by Buyer or by other means acceptable to Buyer.


 


Section 5.13      Use
of Name.


 


(a)          From and after the
Closing, Buyer will acquire Seller’s right to the use of the name “Lymphoseek” and other similar names, and any
service marks, trademarks, trade names, d/b/a names, fictitious names, identifying symbols, logos, emblems or signs containing
or comprising the foregoing, or otherwise used in the Business, including any name or mark confusingly similar thereto (collectively,
the “Seller Marks”) and Seller shall not, and shall not permit any of its Affiliates to, use such name or any
variation or simulation thereof, except to the extent permitted under the License-Back Agreement. The term “Navidea”
is not a Seller Mark and Seller’s use is not subject to the prohibitions in this Section.


 


(b)          Seller hereby grants
to Buyer a limited, non-transferable, non-sublicensable (except to Affiliates), non-exclusive and royalty free license, for the
longer of (i) a 12-month period following the Closing Date, or (ii) the time period required to sell all Product Inventory, to
use the names and marks “Navidea” and any Trademark derived from, confusingly similar to or including the foregoing
in connection with the sale of any Product Inventory.


 


Section 5.14       Regulatory
Matters.


 


(a)          Transfer of Product
Registrations. At the Closing or as soon as possible thereafter (and, in any event, within five Business Days), Seller shall
assign to Buyer, and Buyer shall assume from Seller, all of Seller’s right, title, and interest existing as of the Closing
Date in and to the Product Registrations for the Business Products. Seller and Buyer shall execute and deliver to the FDA and other
appropriate Governmental Authorities letters required by the FDA, the form of which is attached hereto as Exhibit G, and
such documents and instruments of conveyance sufficient to effectuate the transfer of the Product Registrations under the Legal
Requirements of each additional applicable jurisdiction in the Territory on the Closing Date. Each Party shall ensure that each
such document or instrument of conveyance, along with all other information and data submitted in connection therewith, is true,
complete and correct in all material respects as of the date of filing.


 






    	 	 -58-	 



     


    

 


(b)          Transfer of Assumed
Clinical Trials. Seller shall assign to Buyer all of Seller’s right, title, and interest existing as of the Closing Date
in and to the Assumed Clinical Trials and the Assumed Clinical Trial Authorizations, in accordance with the timelines and procedures
set forth in the Transition Services Agreement. Buyer shall take all steps necessary and use its best efforts to achieve such timelines
and perform such procedures. Upon the transfer to Buyer of all Assumed Clinical Trial Authorizations, Buyer, or, if required by
applicable Legal Requirement, Seller shall be responsible for notifying the clinical investigative sites and investigators participating
in the Assumed Clinical Trials (collectively, the “Investigators”) regarding the termination of Seller’s
responsibility for the applicable Assumed Clinical Trial and the assumption of sponsorship and control of such Assumed Clinical
Trial by Buyer. Buyer shall be responsible for executing any required amendments or agreements with the Investigators in connection
with the foregoing, and will be solely responsible for ensuring that all Assumed Clinical Trials are transferred, assumed, and
conducted in compliance with all applicable Legal Requirements, including (i) the FDA Act and its implementing regulations, including,
but not limited to, 21 C.F.R. Parts 11, 50, 54, 56 and 312, (ii) HIPAA and its implementing regulations, including, but not limited
to 45 C.F.R. Part 160 and Part 164, Subparts A and E (Privacy Rule) and C (Security Rule), (iii) Directive 2001/20/EC of the European
Parliament and of the Council, relating to the implementation of good clinical practice in the conduct of clinical trials on medicinal
products for human use and any applicable legislation promulgated thereunder, and (iv) Directive 95/46/EC of the European Parliament
and of the Council, and any applicable legislation promulgated thereunder, and all other Legal Requirements applicable to the Assumed
Clinical Trials.


 


(c)          Governmental Authority
Contacts. From the Closing until the transfer to Buyer of a Product Registration held by Seller pursuant to the terms of this
Section 5.14, (i) Buyer shall have the right to make all communications with any Governmental Authorities in the Territory
regarding such Product Registration; provided that Seller is advised of and included in such communications, and (ii) Seller shall
not make any such communications without the prior approval of Buyer. From and after the transfer to Buyer of each Product Registration
held by Seller pursuant to the terms hereof, Buyer shall be solely responsible and liable for: (A) taking all actions, paying
all fees and conducting all communication with the appropriate Governmental Authority in respect of each Product Registration,
including preparing and filing all reports (including adverse drug experience reports) with the appropriate Governmental Authority;
(B) taking all actions and conducting all communication with third parties in respect of Business Products sold pursuant to
such Product Registration (whether sold before or after transfer of such Product Registrations), including responding to all complaints
in respect thereof; and (C) investigating all adverse drug experiences and product complaints in respect of Business Products.
Notwithstanding the foregoing, Seller, at its sole discretion, may continue to interact with Governmental Authorities regarding
Business Products prior to the transfer of Product Registrations to Buyer.


 


(d)          Product Complaints.
Subject to the provisions of the Safety Data Exchange Agreement, Buyer shall be responsible for responding to any complaint related
to any Business Product that is received by either Buyer or Seller on any date following the later of (i) the Closing Date or (ii)
the transfer date of the applicable Product Registration for such Business Product, from any source and for investigating and analyzing
such product complaint and making required reports to the FDA and equivalent foreign Governmental Authorities, regardless of whether
the Business Product involved was sold by Seller or Buyer. Subject to the provisions of the Transition Services Agreement and the
Safety Data Exchange Agreement, each Party shall promptly notify the other in the event such a Party receives such a product complaint
relating to a Business Product lot manufactured by Seller, and Seller shall, and shall cause its Subsidiaries to, notify Buyer
of all product complaints received by Seller or its Subsidiaries relating to the Business Product. A product complaint received
by Seller or its Subsidiaries that also involves an adverse experience report shall be reported by Seller or its Subsidiaries to
Buyer as set forth in the Transition Services Agreement or the Safety Data Exchange Agreement. Buyer and Seller shall, and Seller
shall cause its Subsidiaries to, cooperate with each other in connection with any investigation and response to any product complaint.

(e)          Permission to Reference
Data. Seller shall not have the right to use, reference, modify, amend or supplement any of the Product Registrations (and
Buyer shall not be obligated to permit any such use, reference, modification, amendment or supplement), except that
Seller shall have the right to reference data in IND 061757 and NDA 202207 only to the extent reasonably necessary for Seller to
develop, manufacture, market, sell or distribute New Products (as defined in the License-back Agreement) under one or more new
product registrations.


 


Section 5.15       Further
Assurances.


 


(a)          Subject to the terms
and conditions of this Agreement, upon the request of either Seller or Buyer, each of the Parties will do, execute, acknowledge
and deliver all such further acts, assurances, deeds, assignments, transfers, conveyances and other instruments and papers as may
be reasonably required or appropriate to carry out the transactions contemplated by this Agreement. Seller shall provide all cooperation
reasonably requested by Buyer in connection with any effort by Buyer to establish, perfect, defend, or enforce its rights in or
to the Acquired Assets, including executing further consistent assignments, transfers and releases, and causing its Representatives
to provide good faith testimony by affidavit, declaration, deposition or other means. Seller will refer all customer inquiries
relating to the Business in North America and the United States territories to Buyer from and after the Closing. Seller will, and
will cause its Affiliates and their respective Representatives to, cooperate and assist Buyer with an orderly transition of the
Business and Acquired Assets to Buyer.


 


(b)          Following the Closing,
in the event an Acquired Asset has not been properly transferred to Buyer or its designee, Seller shall cause all right, title
and interest in and to such Acquired Asset to be transferred to Buyer or its designee, and such transfer shall be effected free
and clear of any Liens (other than Permitted Liens) and without the requirement for Buyer or its Affiliates to pay any additional
consideration or otherwise incur any Liabilities (other than those that would be incurred by any owner of such Acquired Asset as
a result of such ownership).

Section 5.16      Consents
of Third Parties. Nothing in this Agreement nor the consummation of the transactions contemplated hereby shall be construed
as an attempt or agreement to assign any Assumed Contract which by its terms or by Legal Requirement is nonassignable without the
consent of a third party or a Governmental Authority or is cancelable by a third party in the event of an assignment unless and
until such consent shall have been obtained. Seller shall, and shall cause each of its Affiliates to, cooperate with Buyer, at
its request, in endeavoring to obtain any such consent promptly. If any such consent is not obtained, Buyer and Seller shall cooperate
to ensure that Buyer would obtain the benefits and perform and discharge the obligations under the applicable Assumed Contract,
including sub-contracting, sublicensing or subleasing to Buyer, and under which Seller would enforce for the benefit of Buyer,
with Buyer being responsible for the performance and discharge of the obligations of Seller, any and all rights of Seller against
a third party.


 


Section 5.17      Insurance.
With respect to events or circumstances relating to the Acquired Assets, Assumed Liabilities or the Transferred Employees that
occurred or existed prior to the Closing that are covered by Seller’s occurrence-based liability insurance policies and any
workers’ compensation insurance policies and/or comparable workers’ compensation self-insurance, state or country programs
that are in effect prior to the Closing Date (the “Pre-Closing Insurance”), Buyer may make claims under such
policies after the Closing, subject to the terms and conditions thereof, and Seller will take such actions as may be requested
by Buyer in connection with the tendering of such claims to the applicable insurers under such Pre-Closing Insurance and to provide
Buyer with the net proceeds it realizes with respect to such claims. With respect to any open claims against Seller’s insurance
policies relating to the Assumed Assets, Assumed Liabilities or Transferred Employees prior to the Closing, Seller shall use its
commercially reasonable efforts, at Buyer’s expense, to pursue such claims and obtain such expected proceeds.


 


Section 5.18      Access
to Records Post-Closing. For a period of six years after the Closing Date, the Parties will afford one another and their
respective Representatives reasonable access to all of the books and records related to the Business to the extent that such access
may reasonably be required by another Party in connection with Tax or litigation matters (excluding litigation between Buyer or
any Affiliate on the one hand and Seller or any Affiliate on the other hand) relating to the Business prior to the Closing Date.
Such access shall be afforded upon receipt of reasonable advance notice and during normal business hours, and the requesting Party
shall not be responsible for any costs or expenses incurred by it pursuant to this Section ‎5.18,
except for reasonable out-of-pocket expenses incurred by the Party of whom the request was made. If a Party desires to dispose
of any of such books and records prior to the expiration of such six-year period, that Party will, prior to such disposition, give
the other Parties a reasonable opportunity, at such other Party’ expense, to segregate and remove such books and records
as such other Party may select.


 


Section 5.19      Stockholder
Litigation. Prior to Closing, Seller will give Buyer the opportunity to participate in the defense or settlement of any
stockholder litigation against Seller and/or its directors or executive officers relating to the transactions contemplated by this
Agreement, whether commenced prior to or after the execution and delivery of this Agreement. Seller agrees that it will not prior
to Closing settle or offer to settle in exchange for the payment of funds any litigation commenced prior to or after the date of
this Agreement against Seller or any of its directors or executive officers by any stockholder of Seller relating to this Agreement
or any transactions contemplated hereby without the prior written consent of Buyer, which will not be unreasonably withheld or
delayed.

TERMINATION


 


Section 7.1        Termination.
This Agreement may be terminated and the transactions contemplated herein may be abandoned at any time prior to Closing:


 


(a)          by mutual written
consent of Buyer and Seller;


 


(b)          by either Buyer of
Seller, if the Closing will not have been consummated on or before the date that is 180 days after the date of this Agreement (as
may be extended pursuant to the terms hereof, the “Termination Date”), unless extended by written agreement
of the Parties; provided, however, that the right to terminate this Agreement under this paragraph will not be available
to any Party whose failure to fulfill or comply with any obligation or covenant under this Agreement has been the cause of, or
resulted in, the failure of the Closing to occur on or prior to such date;


 


(c)          by Buyer (so long
as Buyer is not then in material breach of any of its representations, warranties or covenants contained in this Agreement), if
a breach of this Agreement by Seller results or would result in any of the conditions set forth in Sections 6.1 or 6.2
not being satisfied and such breach cannot be cured or, if curable, remains uncured for a period of 30 days after Seller has received
written notice from Buyer of the occurrence of such breach (or, if earlier, the Termination Date), and such conditions have not
been waived by Buyer;


 






    	 	 -64-	 



     


    

 


(d)          by Seller (so long
as Seller is not then in material breach of any of its representations, warranties or covenants contained in this Agreement), if
a breach of this Agreement by Buyer results or would result in any of the conditions set forth in Sections 6.1 or 6.3
not being satisfied and such breach cannot be cured or, if curable, remains uncured for a period of 30 days after Buyer has received
written notice from Seller of the occurrence of such breach (or, if earlier, the Termination Date), and such conditions have not
been waived by Seller;


 


(e)          by either Buyer or
Seller, if any Governmental Authority will have issued an Order or Legal Requirement enjoining or otherwise prohibiting the transactions
contemplated by this Agreement and such Order or Legal Requirement will have become final and nonappealable, except that the right
to terminate this Agreement and abandon the transactions contemplated by this Agreement under this paragraph will not be available
to any Party whose failure to fulfill or comply with any obligation or covenant under this Agreement has been the cause of, or
resulted in, the issuance of such nonappealable Order or Legal Requirement;


 


(f)          by either Buyer or
Seller if the Stockholders’ Meeting (including any adjournment or postponement thereof in accordance with the terms of this
Agreement) has concluded, the Seller Stockholders have voted, and the Stockholder Approval was not obtained;


 


(g)          by Buyer if (i) a
Seller Adverse Recommendation Change shall have occurred or Seller has failed to include the Seller Board Recommendation in the
Proxy Statement; (ii) the Seller Board fails to reconfirm the Seller Board Recommendation within five (5) Business Days after receipt
of a request by Buyer, provided that any such request may only be made after notice of any of the following events (as any of such
events may occur from time to time): (A) receipt by Seller of an Acquisition Proposal, (B) any material change to an Acquisition
Proposal, (C) a public announcement of any transaction to acquire a material portion of the assets or business of Seller, including
any Acquired Assets by a Person other than Buyer or any of its Affiliates and (D) any other material event or circumstance reasonably
related to the transactions contemplated by this Agreement or the consummation thereof; (iii) Seller or the Seller Board makes
any public disclosure with respect to any Acquisition Proposal that (A) does not reaffirm the Seller Board Recommendation, (B)
goes beyond a “stop, look and listen” or similar communication of the type contemplated by Rule 14d-9(f) promulgated
under the Exchange Act, or (C) does not expressly reject such Acquisition Proposal; (iv) the Seller Board shall have resolved to
do any of the foregoing; or (v) Seller violates or breaches in any material respect any of its obligations pursuant to Section
5.7; or


 


(h)          by Seller, at any
time prior to obtaining the Stockholder Approval, if the Seller Board shall have approved in compliance with Section 5.7,
and Seller shall concurrently with such termination enter into, an Acquisition Agreement providing for the implementation of the
transactions contemplated by a Superior Proposal; provided, however, that prior
thereto and as a condition precedent thereof, Seller shall have paid the Termination Fee and Expense Reimbursement in accordance
with Section 7.3(a).


 


Section 7.2        Effect
of Termination. If this Agreement is terminated pursuant to Section 7.1 hereof, (a) all rights and obligations of
the Parties hereunder will terminate and no Party will have any Liability to the other, except for obligations of the Parties in
Section 5.1(b), Section 5.5, Section 5.9(b), this Section 7.2, Section 7.3, and Article IX,
which will survive the termination of this Agreement and (b) termination will not relieve any Party from Liability for any intentional
or willful breaches of this Agreement prior to the date of such termination. An “intentional or willful breach” means
a breach or failure to perform, in each case, that is the consequence of an act or omission by a Party with the actual knowledge
that the taking of such act or failure to take such act would, or would reasonably be expected to, cause a breach of this Agreement.

Section 7.3        Termination
Fee; Extension of Supply and Distribution Agreement.


 


(a)          If
(i) Seller terminates this Agreement pursuant to Section 7.1(h) or (ii) Buyer terminates this Agreement pursuant to Section
7.1(g), then Seller shall (A) pay to Buyer $3,000,000 in cash (the “Termination Fee”) and (B) reimburse
Buyer for up to an aggregate of $2,000,000 for the Buyer’s documented out-of-pocket expenses in connection
with this Agreement and the transactions contemplated hereby (the “Expense Reimbursement”); provided,
however, that if the term of the Supply and Distribution Agreement is extended in accordance with Section 7.3(b),
then Buyer will only be eligible to receive the Expense Reimbursement and not the Termination Fee. For the sake of clarity, and
notwithstanding anything to the contrary herein, Seller shall not be obligated to pay the Termination Fee more than once hereunder.


 


(b)          If this Agreement
is terminated pursuant to this Article VII, and within twelve (12) months after such
termination, Seller or any of its Subsidiaries accepts a written offer for, or otherwise enters into an agreement to consummate
or consummates, one or more transactions that, directly or indirectly, result in a sale, license or other transfer of the
Business, the Business Product or all or substantially all of Seller or its assets to a third party (whether or not such transaction
would constitute a Superior Proposal), then subject to the applicable requirements of the FTC Order, the Supply and Distribution
Agreement shall be extended under its existing terms for a period of three years from its then-existing expiration date. If the
Parties are unable to extend the term of the Supply and Distribution Agreement under the FTC Order, due to the action of any other
Governmental Authority or for any other reason, Buyer will be eligible to receive the Termination Fee.


 


(c)          If
this Agreement is terminated pursuant to Section 7.1(c) or 7.1(f), then (i) Seller will pay to Buyer the Expense
Reimbursement and (ii) if (A) prior to such termination there exists an Acquisition Proposal (whether or not such offer or proposal
has been rejected or has been withdrawn prior to the time of such termination) and (B) within twelve (12) months after such termination,
Seller or any of its Subsidiaries accepts a written offer for, or otherwise enters into an agreement to consummate or consummates,
an Acquisition Proposal, then upon the signing of a definitive agreement relating to such Acquisition Proposal, or, if no such
agreement is signed, then upon consummation of any such Acquisition Proposal, Seller will pay to Buyer the Termination Fee unless
Buyer elects to extend the term of the Supply and Distribution Agreement in accordance with Section 7.3(b) and such term
is actually so extended.


 






    	 	 -66-	 



     


    

 


(d)          All
Expense Reimbursements will be paid concurrently with the termination of this Agreement (assuming reasonable documentation therefor
has been provided), and all Termination Fees will be paid (i) no later than five (5) Business Days after the date of such termination
if terminated by the Buyer pursuant to Section 7.1(g), (ii) prior to or concurrently with such termination if terminated
by Seller pursuant to Section 7.1(h), and (iii) the earlier of the date of Seller’s entry into an agreement providing
for, or consummating, an Acquisition Proposal if terminated pursuant to Section 7.1(b), 7.1(f) or 7.1(c),
in each case, unless Buyer elects to have the term of the Supply and Distribution Agreement extended in accordance with Section
7.3(b), in which case, if such term is not so extended (under the FTC Order, due to the action of any other Governmental
Authority or for any other reason), the Termination Fees will be paid no later than five (5) Business Days after Buyer notifies
Seller in writing that Buyer is no longer seeking an extension of the term of the Supply and Distribution Agreement pursuant to
Section 7.3(b).


 


(e)          The
Parties acknowledge that (i) the provisions of this Section 7.3 are an integral part of the Transactions, (ii) the amount
of, and basis for payment of, the Termination Fee (or extension of the Supply and Distribution Agreement) and Expense Reimbursement
are reasonable and appropriate in all respects, and (iii) without those provisions, the Parties would not enter into this Agreement.
Accordingly, if Seller fails to pay in a timely manner the Termination Fee or the Expense Reimbursement, and in order to obtain
such payment, Buyer makes a claim that results in a judgment for the amounts set forth in this Section 7.3, Seller will
pay to Buyer its reasonable costs and expenses (including reasonable attorneys’ fees and expenses) in connection with such
suit, together with interest on the amount set forth in this Section 7.3 at the rate announced by Bank of America, N.A.
as its prime rate in effect on the date such payment was required to be made hereunder. Payment of the amounts described in this
Section 7.3 will not be in lieu of damages incurred in the event of breach of this Agreement.

SURVIVAL; INDEMNIFICATION


 


Section 8.1        Survival
of Representations, Warranties and Covenants. Each of the representations and warranties set forth in this Agreement or
in any certificate delivered pursuant to Section 2.9(a)(iv) or Section 2.9(b)(ii) will survive the Closing and remain
in full force and effect until the date that is the three year anniversary of the Closing Date (the “Survival Date”),
except that the Fundamental Representations will survive the Closing and remain in full force and effect until expiration of the
applicable statute of limitations. The covenants will survive the Closing until the Survival Date; provided, however,
that any covenant contained in this Agreement that, by its terms, provides for performance following the Closing will survive and
continue in full force and effect until such covenant is performed or observed in accordance with its terms. Notwithstanding the
foregoing, any representation or warranty in respect of which indemnity may be sought under this Agreement prior to the Survival
Date will survive the time at which it would otherwise terminate pursuant to the preceding sentence if written notice of the inaccuracy
or breach thereof giving rise to such right of indemnity has been given to the party against whom indemnification may be sought
prior to such time.

Section 8.2        Indemnification.


 


(a)          Indemnification
by Seller. Subject to the limitations expressly set forth in this Article VIII, from and after the Closing, Seller will
indemnify, defend and hold harmless Buyer and its Affiliates, Representatives, equityholders, successors and assigns (all such
foregoing Persons, collectively, the “Buyer Indemnitees”) from and against any Losses the Buyer Indemnitees
may suffer, sustain or become subject to, arising out of, in connection with or resulting from:


 


(i)          any breach
or inaccuracy of any representation or warranty of Seller contained in this Agreement, any other Transaction Document or in any
certificate, instrument or document delivered by Seller pursuant to this Agreement;


 


(ii)         any breach
of any covenant to be performed by Seller pursuant to this Agreement, any other Transaction Document or any agreement or instrument
executed in connection herewith or pursuant hereto;


 


(iii)        any Excluded
Asset or Retained Liability; and


 


(iv)        any items
set forth on Schedule 8.2(a)(iv).


 


(b)          Indemnification
by Buyer. Subject to the limitations expressly set forth in this Article VIII, from and after the Closing, Buyer will
indemnify, defend and hold harmless Seller and Seller’s Affiliates, Representatives, successors and assigns (all such foregoing
persons, collectively, the “Seller Indemnitees”) from and against any Losses Seller Indemnitees may suffer,
sustain or become subject to, arising out of, in connection with or resulting from:


 


(i)          any breach
or inaccuracy of any representation or warranty of Buyer contained in this Agreement, any other Transaction Document or in any
certificate, instrument or document delivered by Buyer pursuant to this Agreement;


 


(ii)         any breach
of any covenant to be performed by Buyer pursuant to this Agreement, any other Transaction Document or any agreement or instrument
executed in connection herewith or pursuant hereto; and


 


(iii)        to the
extent not otherwise subject to indemnity pursuant to this Section 8.2, any Assumed Liability.


 


Section 8.3         Limitations
on Liability; Calculation of Losses.


 


(a)          With respect to Losses
arising pursuant to Sections 8.2(a)(i) or 8.2(b)(i), the Buyer Indemnitees or Seller Indemnitees, as applicable,
will not be entitled to indemnification under this Agreement until the aggregate amount of Losses for which Seller Indemnitees
or the Buyer Indemnitees, as applicable, would be liable thereunder exceeds $400,000, in which case the Buyer Indemnitees or Seller
Indemnitees, as applicable, will be entitled to indemnification for the aggregate amount of all such Losses in excess of such amount.
Seller will not be required to provide indemnification for Losses under Section 8.2(a)(i) in excess of fifteen percent (15%)
of the Purchase Price. Notwithstanding the foregoing, the limitations on liability provided in this Section 8.3(a) will
not apply to indemnification claims with respect to any Fundamental Representation; provided, however, that Seller
will not be required to provide indemnification for aggregate Losses in excess of the Purchase Price under Section 8.2(a)(i)
with respect to any breach of a Fundamental Representation.


 






    	 	 -68-	 



     


    

 


(b)          No party will have
any liability to any other Person with respect to any Losses under this Article VIII arising out of, resulting from, relating
to, in the nature of, or caused by any Liability to the extent that the Liability giving rise to such Loss (or a part thereof)
with respect to such matter has actually been taken into account (and only to the extent so taken) in the determination of Final
Closing Purchase Price as finally determined pursuant to Section 2.7.


 


(c)          For purposes of determining
the amount of any Losses in respect of any breach or inaccuracy of any representation or warranty contained in this Agreement (but
not for purposes of determining whether a breach or inaccuracy has occurred), any express qualifications or limitations set forth
in such representation, warranty or covenant as to materiality, Material Adverse Effect or other words of similar import contained
therein will be disregarded.


 


Section 8.4         Claims
Procedures.


 


(a)          Notice of Claim.
A party that seeks indemnity under this Article VIII (an “Indemnified Party”) will give written notice
(a “Claim Notice”) to the party from whom indemnification is sought (an “Indemnifying Party”)
promptly after such Indemnified Party receives written notice, in the case of a Third Party Claim, or otherwise becomes aware,
in the case of a direct claim, of any such claim, event or matter as to which indemnity may be sought; provided, however,
that no delay on the part of an Indemnified Party in notifying the Indemnifying Party will relieve the Indemnifying Party from
any obligation hereunder unless (and then solely to the extent) the Indemnifying Party is materially prejudiced thereby. Any Claim
Notice will contain (i) a description and, if known, the estimated amount of any Losses incurred or reasonably expected to be incurred
by the Indemnified Party, and (ii) a reasonable explanation of the basis for the Claim Notice to the extent of the facts then known
by the Indemnified Party.


 


(b)          Direct Claims.
Within 30 days after delivery of a Claim Notice relating to a claim for indemnification other than a Third Party Claim, the Indemnifying
Party will deliver to the Indemnified Party a written response in which the Indemnifying Party will either: (i) agree that the
Indemnified Party is entitled to indemnification for all of the Losses at issue in the Claim Notice; or (ii) dispute the Indemnified
Party’s entitlement to indemnification by delivering to the Indemnified Party a written notice (an “Objection Notice”)
setting forth in reasonable detail each disputed item, the basis for each such disputed item and setting forth any items in the
Claim Notice with which the Indemnifying Party agrees. If the Indemnifying Party fails to take either of the foregoing actions
within 30 days after delivery of the Claim Notice, then the Indemnifying Party will be deemed to have irrevocably accepted the
Claim Notice and the Indemnifying Party will be deemed to have irrevocably agreed to pay the Losses at issue in the Claim Notice.
If the Indemnifying Party delivers an Objection Notice to the Indemnified Party within 30 days after delivery of the Claim Notice,
then the dispute may be resolved by any legally available means consistent with the provisions of this Agreement. For the avoidance
of doubt, any item or amount set forth in a Claim Notice that is not disputed in the Objection Notice will be deemed to be final,
binding and conclusive upon the Parties from and after such time as the Objection Notice is delivered.


 






    	 	 -69-	 



     


    

 


(c)          Third Party Claims.


 


(i)          Subject
to paragraphs (iii), (iv) and (v) below, Buyer, in its capacity as either Indemnified Party or Indemnifying Party, will have the
right to defend any claim described in a Claim Notice that relates to a claim asserted by a third party (a “Third Party
Claim”) with counsel of Buyer’s choice, reasonably satisfactory to Seller in cases where Buyer is the Indemnifying
Party, so long as, if Buyer is the Indemnifying Party, (A) Buyer notifies Seller, within 30 days after the Indemnified Party has
given notice of the Third Party Claim to the Indemnifying Party, that Seller is assuming the defense of such Third Party Claim
and (B) Buyer conducts the defense of the Third Party Claim in an active, diligent and reasonable manner. In the event that Buyer
fails to assume the defense of any Third Party Claim within 30 days after notice thereof is given to the Indemnifying Party by
the Indemnified Party, Seller will have the right to undertake the defense of such Third Party Claim (which will be undertaken
at the expense and for the account of Buyer only if Buyer is the Indemnifying Party in such matter).


 


(ii)         So long
as the conditions set forth in Section 8.4(c)(i) are and remain satisfied (A) Buyer may conduct the defense of the Third
Party Claim in accordance with Section 8.4(c)(i), (ii) Seller may retain separate co-counsel at its sole cost and expense,
and (B) where Buyer is the Indemnifying Party, Buyer will not, without the prior written consent of Seller, consent to any admission
or the entry of any Order with respect to the matter, or enter into any settlement which (1) imposes an injunction or other equitable
relief upon the Indemnified Party, (2) does not include an unconditional provision whereby the plaintiff or claimant in the matter
releases the Indemnified Party from all Liability with respect thereto.


 


(iii)        Notwithstanding
the above, Buyer will not be entitled to control (but will be entitled to participate at its own expense in the defense of), and
Seller will be entitled to have sole control over, the defense or settlement, compromise, admission, or acknowledgment of any Third
Party Claim as to which Buyer fails to assume the defense within 30 days after the Indemnified Party gives notice thereof to the
Indemnifying Party.


 


(iv)       Notwithstanding
paragraphs (i) and (ii) above, Seller shall have the right to submit any Third-Party Claim that is solely for monetary damages
to its insurer if it reasonably believes that such insurer’s insurance policy will cover the Losses subject to such claim.
If the insurer agrees to take over such Third-Party Claim, the Parties agree to permit such insurer to manage the defense of such
Third-Party Claim; provided that Buyer may, at its own expense, participate in such defense to the extent permitted by such insurer.

Section 8.5        Payment
of Claim. Subject to the limitations set forth herein, in order to satisfy any indemnification obligations of Seller with
respect to any claim for indemnification pursuant to this Article VIII, a Buyer Indemnitee will have the right to recover
indemnifiable Losses that have been incurred (i) first, from amounts set off with respect to a claim for indemnification from any
Earnout Payment (including, for the avoidance of doubt, any Guaranteed Payment), and (ii) second, from Seller.


 


Section 8.6        Exclusive
Remedy. From and after the Closing, other than with respect to fraud and any indemnity claims under the Supply and Distribution
Agreement to the extent not released pursuant to Section 5.9(b), the sole and exclusive remedy of any Indemnified Party
with respect to any and all Losses arising in connection with the representation, warranties and covenants set forth in this Agreement
will be pursuant to the indemnification obligations set forth in this Article VIII. The parties will be entitled to injunctive
relief or specific enforcement of the provisions of this Agreement pursuant to Section 9.12. To the extent an Indemnified
Party is entitled to recover any Losses pursuant to Article VIII of this Agreement and pursuant to the Supply and Distribution
Agreement, the Indemnified Party will only be permitted to recover such Losses only once without duplication.


 


Section 8.7        Investigation.
The right to indemnification or any other remedy based on representations, warranties, covenants and agreements of Seller in this
Agreement, or any document, certificate or other instrument required to be delivered by Seller under this Agreement will not be
affected by any investigation conducted by any Indemnified Party or any other Person at any time, or any knowledge acquired (or
capable of being acquired) by any Indemnified Party or any other Person at any time, whether before or after the execution and
delivery of this Agreement and prior to the Closing, with respect to the accuracy or inaccuracy of, or compliance with, any such
representation, warranty, covenant or agreement.


 


Section 8.8        Treatment
of Indemnity Payments. Any amount paid for indemnification under this Article VIII will be treated as an adjustment
to the Purchase Price, including for all Tax purposes, except as otherwise required by any Legal Requirement.


 


Section 8.9        Insurance.
The amount of any Loss subject to indemnification under this Article VIII shall be calculated net of any insurance proceeds
received by the Indemnified Party or their respective Affiliates (“Insured Party”) from one of the Indemnifying
Party’s insurers on account of such Loss. If an insurance recovery is made by any Insured Party from one of the Indemnifying
Party’s insurers with respect to any Loss for which any Indemnified Party has been indemnified hereunder, then a refund equal
to the amount of such recovery shall be made promptly to the Indemnifying Party that made or directed such indemnification payments
to such Indemnified Party.

(a)          This Agreement may
not, without the prior written consent of the other Party, be assigned, and any attempted assignment will be null and void; provided,

This Agreement may be executed in two or more counterparts for the convenience of the Parties, each of which will be deemed an

Section 9.8        Titles
and Headings. The titles, captions and table of contents in this Agreement are for reference purposes only, and will not
in any way define, limit, extend or describe the scope of this Agreement or otherwise affect the meaning or interpretation of this
Agreement.


 


Section 9.9        Entire
Agreement. This Agreement, including the Exhibits and Schedules attached thereto, the Transaction Documents and the Confidentiality
Agreement, constitute the entire agreement among the Parties with respect to the matters covered hereby and supersede all previous
written, oral or implied understandings among them with respect to such matters, including without limitation the Letter of Intent

Section 9.10      Severability.
The invalidity of any portion hereof will not affect the validity, force or effect of the remaining portions hereof. If it is ever
held by any Governmental Authority of competent jurisdiction that any restriction hereunder is too broad to permit enforcement
of such restriction to its fullest extent, such restriction will be enforced to the maximum extent permitted by Legal Requirement
and, to the extent necessary, the Parties will amend or otherwise modify this Agreement to replace any provision contained herein
that is held invalid or unenforceable with a valid and enforceable provision giving effect to the original intent of the Parties.


 


Section 9.11      No
Strict Construction. Each of the Parties acknowledges that this Agreement has been prepared jointly by the Parties, and
will not be strictly construed against any Party. As a consequence, the Parties do not intend that the presumptions of any Legal

Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement
were not performed by the Parties in accordance with their specific terms or were otherwise breached. It is accordingly agreed
that each Party will be entitled to seek an injunction or injunctions to prevent breaches or threatened breaches of this Agreement
and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction and that this will include the
right of a Party to cause the other to fully perform the terms of this Agreement to the fullest extent permissible pursuant to
this Agreement and applicable Legal Requirement and to thereafter cause this Agreement and the transactions contemplated hereby
to be consummated on the terms and subject to the conditions thereto set forth in this Agreement. Such remedies will, however,
be cumulative and not exclusive and will be in addition to any other remedies that any party may have under this Agreement or otherwise.
The Parties agree that the right of specific performance and other equitable relief is an integral part of the transactions contemplated
by this Agreement and without that right, neither Party would have entered into this Agreement. Each of the Parties hereby waives
(a) any defenses in any action for specific performance, including the defense that a remedy at law would be adequate and
(b) any requirement under any Legal Requirement to post a bond or other security as a prerequisite to obtaining equitable
relief.


 


Section 9.13     Waiver
of Jury Trial. EACH OF THE PARTIES IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN RESPECT
OF ANY LITIGATION BASED ON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT, ANY OF THE AGREEMENTS DELIVERED IN CONNECTION
HEREWITH OR THE TRANSACTIONS CONTEMPLATED BY ANY TRANSACTION DOCUMENT, OR ANY COURSE OF CONDUCT, COURSE OF DEALING, VERBAL OR WRITTEN
STATEMENT OR ACTION OF ANY PARTY.


 


Section 9.14     Failure
or Indulgence not Waiver. No failure or delay on the part of any Party in the exercise of any right hereunder will impair
such right or be construed to be waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein,
nor will any exercise of any such right preclude any other or further exercise thereof or any other right.


 


Section 9.15     Amendments.
This Agreement may be amended, at any time by the Parties. This Agreement may not be amended or modified except by an instrument
in writing signed on behalf of the Parties.


 


Section 9.16    Costs
of Enforcement.  If any party institutes
any legal suit, action or proceeding against the other Party to enforce its rights under this Agreement, the prevailing party
in a final, non-appealable judgment regarding the suit, action or proceeding will be entitled to reimbursement of its costs incurred
in conducting the suit, action or proceeding, including reasonable attorneys’ fees and costs. For purposes of this Section
9.16, there will be a “prevailing party” only to the extent a Party succeeds on all of its claims made in connection
with such legal suit, action or proceeding. Notwithstanding the foregoing, nothing in this Section 9.16 shall limit or
otherwise effect Buyer’s right to be indemnified for attorney fees under Article VIII.

Exhibit D


 


Form of License-Back Agreement





  


This License-Back Agreement
and its Exhibits (this “Agreement”), is entered into on ____________ (the “Effective Date”)
between Cardinal Health 414, LLC, a Delaware limited liability company (the “Buyer”), and Navidea Biopharmaceuticals,
Inc., a Delaware corporation (the “Seller”). Buyer and Seller are each individually referred to herein as a
“Party” and are collectively referred to herein as the “Parties”.


 


INTRODUCTION


 


The Parties have entered
into an Asset Purchase Agreement, dated November 23, 2016 (the “APA”), under which, among other things, the
Parties agreed that at Closing, Buyer and Seller would execute and deliver to each other a License-Back Agreement.


 


The Parties agree that
this Agreement is the License-Back Agreement as contemplated under the APA.


 


The Parties also intend
for this Agreement to set forth certain rights and obligations with respect to the Licensed IP, including rights and obligations
with respect to the prosecution, maintenance, enforcement and defense of the Licensed IP.


 


All capitalized terms
not defined in this Agreement have the meanings given to them in the APA.


 


In consideration of
the representations, warranties, covenants and agreements contained in this Agreement and the APA and other good and valuable consideration,
the receipt of which is hereby acknowledged, the Parties, intending to be legally bound, agree as follows:


 


		1.	License Grant



 


		1.1	License Grant. Buyer hereby grants to Seller a perpetual (except as provided in Sections
‎5.2 and ‎5.3), transferable and royalty-free
license to use the Intellectual Property Rights included in the Acquired Assets and owned by Buyer as of the Effective Date (the
“Licensed IP”) only to the extent reasonably necessary for Seller to do any of the following which would otherwise
infringe the Licensed IP but for the grant of this license (together, the “Field”):



 


		(a)	on an exclusive basis (subject to Section ‎1.9), develop,
manufacture, market, sell and distribute new pharmaceutical and other products that are not Competing Products (collectively, “New
Products”); and



 


		(b)	on a non-exclusive basis, develop, manufacture, market, sell and distribute the Business Product
anywhere in the world except in the Territory (the “Licensed Territory”) (such Business Product manufactured,
marketed, sold or distributed in the Licensed Territory, the “Ex-America Product”).



 




     


     


    

 


As used in this Agreement, a “Competing
Product” is any pharmaceutical or other product that: (i) accumulates in lymphatic tissue or tumor-draining lymph
nodes for the purpose of (A) lymphatic mapping or (B) identifying the existence, location or staging of cancer in a body; (ii) provides
for or facilitates any test or procedure that is reasonably substitutable for any test or procedure provided for or facilitated
by the Business Product; or (iii) is marketed for unapproved uses that allow such product to compete with the Business Product.


 


		1.2	Buyer’s Restricted Use. During the term of this Agreement, subject to Section ‎1.9,
Buyer agrees not to use the Intellectual Property Rights included in the Acquired Assets to develop, manufacture, market, sell
or distribute any product other than the Business Product or any other product that (a) accumulates in lymphatic tissue or tumor-draining
lymph nodes for the purpose of (i) lymphatic mapping or (ii) identifying the existence, location or staging of cancer in a body,
or (b) provides for or facilitates any test or procedure that is reasonably substitutable for any test or procedure provided for
or facilitated by the Business Product.



 


		1.3	Sublicenses.



 


		(a)	The license granted under Section ‎1.1 (the “License
Grant”) may be sublicensed to any third party with prior written notice to Buyer, provided that Seller shall ensure that
any sublicense of the License Grant that it (or its sublicensee) enters into (a “Sublicense”):



 


		(i)	contains terms no less protective of Buyer’s rights than those set forth in this Agreement;



 


		(ii)	if the sublicensee is a sublicensee of the Licensed IP with respect to the New Products, expressly
prohibits the sublicensee from manufacturing, marketing, selling or distributing any Competing Products and expressly provides
Seller with a right to terminate the Sublicense in the event the sublicensee fails to comply with such prohibition; and



 


(iii)        is
not in conflict with this Agreement.


 


		(b)	Seller shall and shall ensure that its sublicensees provide Buyer with a complete electronic or
paper copy of each Sublicense within thirty (30) days after execution of the Sublicense.



 


		(c)	Seller shall be fully responsible and liable to Buyer for any breach of the terms of this Agreement
or any sublicense by its sublicensees (or its sublicensees’ sublicensees).



 




    	 	2	 



     


    

 


		(d)	In the event any sublicensee manufactures, markets, sells or distributes any Competing Products,
in addition to exercising any termination rights it may have under the relevant sublicense, Seller shall immediately: (i) notify
Buyer in writing, including providing Buyer with all information regarding the Competing Products sold or distributed by the sublicensee
as requested by Buyer; and (ii) pay to Buyer an amount equal to two times (2x) Buyer’s then-current list price of the Business
Product in the Territory (as of the date of Seller’s notice under clause (i)) for each Competing Product that the sublicensee
has sold or distributed. Seller acknowledges that in the event a Seller sublicensee sells or distributes any Competing Product,
the damages which Buyer will sustain may be difficult to ascertain and such amount in clause (ii) is reasonable, does not
constitute a penalty, and Seller shall not contest the reasonableness of such amount in any Action commenced by either Party with
respect to this Agreement.



 


		1.4	Seller Marks. Exhibit A to this Agreement sets forth the Contracts (the “Existing
Licenses”) under which Seller has committed, as of the date of the APA, to license the trademarks identified in the exhibit
(the “Licensed Marks”) to the distributors identified in the exhibit (the “Licensed Distributors”)
for the purpose of using such Licensed Marks in connection with marketing, selling and distributing the Ex-America Products in
one or more jurisdictions of the Licensed Territory. Subject to the terms and conditions of this Agreement, Buyer hereby grants
to Seller a non-transferable and royalty-free nonexclusive right to allow the Licensed Distributors to use the Licensed Marks only
for the purpose of marketing, selling and distributing the Ex-America Products in one or more jurisdictions of the Licensed Territory,
subject to the terms and conditions of the Existing Licenses and this Section ‎1.4). Except
as expressly set forth in the foregoing license grant (“Trademark License”), nothing in this Agreement grants
or confers to Seller (or its distributors) any right, title or interest in or to the Seller Marks or any goodwill associated with
the Seller Marks (notwithstanding that they form part of the Acquired Assets) and Seller and its distributors have no right to
use the Seller Marks in any other manner, for any other purpose or in any other territory. In addition, nothing in this Agreement
shall be construed as limiting, preventing, or restricting, in any manner, Buyer’s right to use, to license any third party
to use, or to register the Seller Marks in any manner whatsoever anywhere in the world. Except pursuant to the Existing Licenses,
Seller shall not at any time make any commitments or grant any rights with respect to the Seller Marks without the prior written
consent of Buyer. Without limiting the foregoing:



 


		(a)	Seller shall ensure that the Licensed Marks are not used by any Licensed Distributors in a manner
that would disparage, tarnish, or dilute the distinctive quality of the Licensed Marks or the reputation or goodwill represented
by the Licensed Marks or which would reflect adversely on the Seller Marks, Buyer or its Affiliates, the Ex-America Products or
any other products or services of Buyer or its Affiliates;



 


		(b)	Seller shall, to the extent permitted by the applicable Existing License (or, if not permitted
by the applicable Existing License, Seller shall use its commercially reasonable efforts to), cause the Licensed Distributor, upon
reasonable advance notice, to allow Seller and its designees (including Buyer and its Affiliates) to access and inspect any and
all of the Licensed Distributor’s facilities and to inspect, copy and audit the Licensed Distributor’s books and records,
in each case, to the extent related to the Licensed Distributor’s use of any of the Licensed Marks and to confirm that the
Licensed Marks are not used or planned to be used by the Licensed Distributor in any manner that would or could reasonably be expected
to result in a violation of Section ‎1.4(a);



 




    	 	3	 



     


    

 


		(c)	without limiting any rights or remedies available to Buyer, in the event Seller or its distributors
use any Seller Marks outside the scope or in contravention of the Trademark License or this Section ‎1.4,
Seller shall turn over to Buyer all revenues derived from such unauthorized use and promptly withdraw the relevant product and
materials from the market in consultation with Buyer;



 


		(d)	Seller shall not modify the Licensed Marks in any form or manner unless approved in advance in
writing by Buyer;



 


		(e)	Seller shall pass through to Buyer any royalties paid by a Licensed Distributor to Seller to the
extent expressly attributable to a license of the Licensed Marks and not attributable to any other rights licensed by Seller to
the Licensed Distributor; and



 


		(f)	to the extent Seller or its distributors market, distribute or sell any New Products or Ex-America
Products not covered by the Trademark License under this Agreement, such New Products and Ex-America Products shall be:



 


		(i)	marketed, distributed and sold under a different trademark, service mark, service names, brand,
trade dress and logos than any Seller Marks, including “Lymphoseek®”; and



 


		(ii)	otherwise differentiated from the Seller Marks, including “Lymphoseek®” and the
Business Product, to ensure that end customers in the Licensed Territory and other third parties could not reasonably confuse or
substitute such New Products or Ex-America Products for the Business Product or Seller Marks.



 


Without limiting any other remedies or rights that may
be available to Buyer (including under Section ‎7.4), Buyer may immediately terminate the Trademark License upon written notice
to Seller if Seller breaches this Section ‎1.4 and fails to remedy such breach within 30 days after receiving notice of the
breach by Buyer; provided that (A) if the breach is attributable solely to a particular Licensed Distributor, then such termination
shall apply only with respect to such Licensed Distributor and the Trademark License will remain in full force and effect with
respect to Seller and each other Licensed Distributor, and (B) if the breach is attributable solely to Seller, then such termination
shall apply only with respect to Seller and the Trademark License (as a pass through to each Licensed Distributor) will remain
in full force and effect with respect to each Licensed Distributor as long as such Licensed Distributor grants Buyer the right
as an express third party beneficiary to enforce Seller’s rights under the applicable Existing License.


 




    	 	4	 



     


    

 


		1.5	Patent Marking. Seller shall mark any and all New Products and Ex-America Products in accordance
with the applicable patent marking laws. Seller shall be responsible for all monetary and legal liabilities arising from or caused
by failure to abide by applicable patent marking laws and any type of incorrect or improper patent marking for any New Products
or Ex-America Products.



 


		1.6	Government Rights. Seller acknowledges and agrees that the License Grant shall be subject
to any rights or duties to the applicable Governmental Authorities or any academic institutions if the Intellectual Property Rights
were created or invented in the course of government-funded or academic institution-funded research or using government or academic
institution resources or personnel prior to the Effective Date, and Seller agrees that it would be subject to such rights and duties.



 


		1.7	Permission to Reference Data. Seller shall not have the right to use, reference, modify,
amend or supplement any of the Product Registrations (and Buyer shall not be obligated to permit any such use, reference, modification,
amendment or supplement), except that Seller shall have the right to reference data in IND 061757 and NDA 202207
only to the extent reasonably necessary for Seller to develop, manufacture, market, sell or distribute New Products under one or
more new product registrations.



 


		1.8	Costs and Expenses.



 


		(a)	Seller shall be responsible for all costs and expenses incurred by or on behalf of Buyer in connection
with Seller’s exercise of its rights under this Agreement, including any costs and expenses incurred by or on behalf of Buyer
if Seller submits any new IND, NDA, clinical trial or other product registration or references Buyer’s data as described
in Section 1.7.



 


		(b)	Buyer may invoice Seller any costs and expenses payable under this Agreement and Seller shall pay
each invoice within 30 days of the date of each invoice.



 




    	 	5	 



     


    

 


		1.9	Breach of License Grant. If Seller markets, sells or distributes the Business Product or
any Competing Product in the Territory and Seller fails to cure such breach to Buyer’s reasonable satisfaction within 30
days of Buyer’s notice to Seller (or if such cure cannot reasonably be accomplished within such original 30-day period, and
Seller notifies Buyer in writing within such 30-day period of Seller’s intention and proposed steps to cure and thereafter
diligently pursues the same, then Seller will have such additional period of time (not to exceed 60 days following expiration of
the original 30-day period) as is necessary to accomplish such cure), then, without limiting any other remedies or rights that
may be available to Buyer (including under Section ‎7.4), upon notice from Buyer to Seller,
(a) the exclusive license granted to Seller under Section ‎1.1(a) shall be converted to
a non-exclusive license, and Buyer’s obligations and Seller’s rights under Sections ‎1.2,
‎2.4, ‎2.5 and ‎2.6
shall no longer apply and (b) Seller shall use reasonable best efforts to cause Buyer to receive the same or substantially similar
rights, on a non-exclusive basis, as Seller currently has under the License Agreement between Seller and the University for Case
No. SD1998-088, effective July 14, 2014, which contemplates a field of use for all diagnostic, detection and therapeutic uses in
targeting of CD206 receptor positive cells, excluding diagnostic uses covered by license agreement #2002-03-0237.



 


		2.	Ownership, Prosecution, Defense and Enforcement of Licensed IP



 


		2.1	No Other Rights. Nothing in this Agreement shall be interpreted as conferring by implication,
estoppel or otherwise any license or rights under any Intellectual Property Rights or other rights, other than those expressly
granted under the License Grant. Seller acknowledges and agrees that Buyer has no obligation to deliver or furnish to Seller any
information, materials or items other than those set forth in this Agreement or the APA.



 


		2.2	Ownership. Subject to the License Grant, Buyer shall remain the sole and exclusive owner
of any and all right, title and interest in and to the Licensed IP, and all modifications, improvements, enhancements, and derivative
works of the Licensed IP created, conceived, discovered, first reduced to practice or invented by or on behalf of Buyer. Seller
shall not, and shall not direct or aid any third party to, attack, dispute, or otherwise challenge Buyer’s ownership of or
the validity of the Licensed IP. Subject to Buyer’s ownership in and to the Licensed IP, Seller shall remain the sole and
exclusive owner of any and all right, title and interest in and to any modifications, improvements, enhancements, and derivative
works of the Licensed IP created, conceived, discovered, first reduced to practice or invented by or on behalf of Seller, provided
that Seller shall not, at any time during the term of this Agreement or thereafter, file or have filed any patent applications
that claim priority to any Licensed IP except with the prior written consent of Buyer (which may be reasonably withheld by Buyer).



 


		2.3	Buyer’s Prosecution, Defense and Enforcement Rights. Without limiting the foregoing
but subject to Buyer’s obligations under Section ‎2.4, Buyer shall retain the sole
right and full discretion to determine the protection mechanism of the Licensed IP and to file, record, prosecute, abandon prosecution
of, maintain, discontinue maintenance of and/or defend or enforce its right, title and interest in and to any and all Licensed
IP. Buyer shall be entitled to any and all recovery or settlement received in connection with any suit or claim initiated or pursued
by Buyer.



 




    	 	6	 



     


    

 


		2.4	Seller’s Prosecution Rights. Seller may from time to time consult with Buyer (or Buyer’s
external patent counsel) regarding the filing, prosecution or maintenance of any patents or patent applications that form part
of the Licensed IP and comment on all relevant material matters related to prosecution of the Licensed IP that include claims of
a scope that in whole or in part are directed to the Field. Buyer shall reasonably consider any such comments provided by Seller,
and Buyer will within a reasonable time either:



 


		(a)	implement such comments received from Seller itself (or direct its external patent counsel to do
so), at Seller’s sole cost and expense (including legal fees and filing, prosecution and maintenance fees) and in a manner
as reasonably determined by Buyer having regard to how Seller’s comments may affect any claims directed in whole or in part
to the Business or the Business Product. Buyer shall keep Seller reasonably informed regarding matters related to the implementation
of Seller’s comments under this clause (a) and shall, without limitation: (i) provide (or direct its external patent counsel
to provide) Seller with access to copies of all material documentation and correspondence relating to the filing, prosecution and
maintenance of the relevant Licensed IP so that Seller may remain informed with respect thereto; and (ii) give Seller, at Seller’s
expense, reasonable opportunity to consult with Buyer (or its external patent counsel) regarding such filing, prosecution, maintenance
and to comment on all relevant material matters related to prosecution of the Licensed IP with claims of a scope that in whole
or in part are directed to the Field. Seller shall, at its sole cost and expense, provide all reasonable assistance to Buyer, as
requested by Buyer, to assist Buyer in implementing Seller’s comments under this clause (a); or



 


		(b)	authorize Seller to implement such comments itself, in which case Seller shall be completely responsible
for the prosecution of the relevant Licensed IP, and all related costs and expenses (including legal fees and filing, prosecution
and maintenance fees). Seller shall keep Buyer reasonably informed regarding matters related to its prosecution activities under
this clause (b) and shall, without limitation: (i) provide (or direct its external patent counsel to provide) Buyer with access
to copies of all material documentation and correspondence relating to the filing, prosecution and maintenance of the Licensed
IP so that Buyer may remain informed with respect thereto; and (ii) give Buyer, at Buyer’s expense, reasonable opportunity
to consult with Seller (or its external patent counsel) regarding such filing, prosecution, maintenance and to comment on all relevant
material matters related to prosecution of the Licensed IP (particularly, but without limitation, to matters that may affect any
claims directed to the Business or the Business Product), provide input on the drafting of any claims and amendments to claims
and review draft responses prior to filing with Governmental Authorities, such that Buyer is given a reasonable opportunity to
provide meaningful input in advance of any applicable deadlines. Seller shall ensure that all comments by Buyer are reasonably
considered by Seller and its prosecuting counsel and shall implement any comments by Buyer that relate to the Business or the Business
Product. Buyer shall, at Seller’s sole cost and expense, provide all reasonable assistance to Seller and provide and execute
all documents prepared and reasonably requested by Seller, to assist Seller in exercising its rights under this clause (b).



 




    	 	7	 



     


    

 


Buyer’s
decision to implement Seller’s comments under clause (a) or authorize Seller to implement such comments itself under clause
(b) shall be made in consultation with Seller, having reasonable regard to the subject matter, scope and territory of the Licensed
IP, the nature of the proposed prosecution activities, Seller’s interests in protecting its rights with respect to the Field
and Buyer’s interests in protecting its rights with respect to the Business Product and Business.


 


		2.5	Abandonment of Licensed IP. In the event Buyer elects, in its sole discretion, not to pursue,
maintain or retain a particular patent or patent application that forms part of the Licensed IP, Buyer shall so notify Seller and,
subject to the rights of relevant Governmental Authorities and any other contractual obligations to research sponsors, Buyer will
authorize Seller to assume the filing, prosecution and/or maintenance of such patent or patent application in Buyer’s name
or Seller’s name, at Seller’s option, and at Seller’s sole cost and expense, and such notification will be in
reasonable time for Seller to satisfy any agency or judicial requirements. In such event, Buyer shall provide to Seller any authorization
necessary to permit Seller to pursue and/or maintain such patent right, on such economic and other terms as the Parties shall mutually
agree.



 


		2.6	Defense and Enforcement of Licensed IP. The Parties shall keep each other informed of any
alleged infringement by a third party of the Licensed IP in the Field and any legal or administrative action by any third party
against the Licensed IP in the Field, including any oppositions, interference, derivation, revocation, reexamination, inter
partes review, post-grant review, nullity action, compulsory license proceeding, or declaratory judgment action (“Invalidity
Action”). Any defense of an Invalidity Action by Seller shall be governed by this Section ‎2.6.
Seller may defend or enforce any Licensed IP with the prior written consent of Buyer, which shall not be unreasonably withheld
or delayed. In the event Buyer provides Seller with written consent to defend or enforce any Licensed IP, Seller shall defend or
enforce the Licensed IP at Seller’s sole cost and expense, shall keep Buyer reasonably informed regarding matters related
to its activities under this Section ‎2.6 and, without limitation:



 


		(a)	provide (or direct its external counsel to provide) Buyer with access to copies of all material
documentation and correspondence relating to the defense and enforcement so that Buyer may remain informed with respect thereto;



 


		(b)	give Buyer reasonable opportunity to consult with Seller (or its external counsel) regarding such
defense and enforcement and to comment on all relevant material matters related to defense and enforcement of the Licensed IP (particularly
but without limiting to matters that may affect any claims directed in whole or in part to the Business or the Business Product)
and provide input on strategy, filings and selection and use of outside counsel; and



 




    	 	8	 



     


    

 


		(c)	ensure that all comments by Buyer are reasonably considered by Seller and its counsel and shall
implement any and all comments provided by Buyer that relate to the Business or the Business Product.



 


Buyer shall, at Seller’s
request and sole cost and expense, provide all reasonable assistance to Seller, provide and execute all documents prepared and
reasonably requested by Seller and, if required, join Seller as a party plaintiff in the relevant suit, to assist Seller in exercising
its rights under this Section ‎2.6. Buyer may also voluntarily join Seller as a party plaintiff in any related suit with counsel
of its choice, and Seller hereby authorizes Buyer to do so. Notwithstanding anything in the foregoing, Seller shall not waive,
release, settle or compromise any claim or make any admission as to Buyer or Buyer’s Affiliates, without the prior written
approval of Buyer, which shall not be unreasonably withheld or delayed. Any recovery or settlement derived from any suit or claim
initiated or pursued by Seller under this Section ‎2.6 shall first be applied to the Parties’ costs and expenses,
including attorney’s fees, in connection therewith, and any balance remaining shall then be divided equally between the Parties.


 


		3.	Supply of New Products and Ex-America Products to Buyer



 


		3.1	Right of First Offer. If at any time during the term of this Agreement, Seller decides to
market, launch, sell or distribute any New Product, Seller shall immediately notify Buyer in writing (the “Offer Notice”).
Except pursuant to a right of first offer granted pursuant to any of the Contracts listed in Exhibit B (each, a “Superior
ROFO”), Seller shall not offer any third party a right to market, sell and/or distribute the New Product until at least
sixty (60) days after the Offering Notice is given to Buyer (plus the amount of time in which any Licensed Distributor has to exercise
a Superior ROFO). Following Buyer’s receipt of the Offer Notice, at Buyer’s option, which Buyer may exercise in its
sole discretion, the Parties shall negotiate in good faith the terms that will apply to Buyer’s marketing, selling and/or
distribution of such New Product (the “Distribution Agreement”), subject to Section ‎3.2
and provided that (i) Buyer may terminate the negotiations at any time, and (ii) Seller may terminate the negotiations in the event
a Licensed Distributor exercises the same right under a Superior ROFO. If the Parties, despite their good faith negotiations are
unable to agree to a Distribution Agreement during such 60-day period, as extended (or such other period as mutually agreed to
by the Parties), or Buyer or Seller terminates the negotiations as provided above, Seller shall have the right to market, launch,
sell and distribute the New Product without restriction hereunder.

		3.2	Most Favored Customer. Seller acknowledges and agrees that the terms and conditions under
which Seller may grant Buyer a right to market, sell or distribute any New Product under a Distribution Agreement, including the
amounts payable by Buyer under the Distribution Agreement (the “Distribution Terms”), shall be at least as favorable
as the terms granted by Seller to its other distributors, customers or resellers of the New Product in the country in which Buyer
intends to market, sell or distribute the New Product (if applicable), under agreements signed before, on or after the effective
date of the Distribution Agreement and to whom Seller provides products similar to the New Product. If the terms granted by Seller
to another one of its distributors, customers or resellers are, considering the foregoing, more favorable than the terms under
the Distribution Terms (such as if the amounts payable by the Seller’s other distributors, customers or resellers are lower
than the amounts payable by Buyer), then the Distribution Agreement shall be retrospectively amended to provide Buyer with the
benefit of such more favorable terms on and from the first date on which such more favorable terms first became effective for Seller’s
other distributors, customers or resellers. Every six (6) months commencing from the effective date of the Distribution Agreement,
Seller shall certify in writing to Buyer that it has complied with this Section.



 


		3.3	No Obligation. Without limiting Buyer’s rights under Section ‎3.1
or ‎3.2, nothing in this Agreement shall create an obligation on Buyer to market, launch,
buy, sell, supply, resell or distribute any New Products or Ex-America Products.



 


		4.	UCSD Patents



 


		4.1	Definitions. For the purpose of this Section ‎4
only, any capitalized terms which have not been defined in this Agreement have the meanings given to them in the UCSD License Agreements
(defined below).



 


		4.2	Background. Each of the Parties has entered into a license agreement with The Regents of
the University of California (the “University”), represented by its San Diego campus (the “UCSD License
Agreements”), for the license of the University’s rights in any of the following: (a) the US patent application
(serial number 09/569,466, titled “MACROMOLECULAR CARRIER FOR DRUG AND DIAGNOSTIC AGENT DELIVERY”) disclosing and claiming
the Invention, filed by Inventor and assigned to the University; (b) continuing applications thereof including divisions,
substitutions, and continuations-in-part (but only to the extent the claims thereof are entirely supported in the specification
and entitled to the priority date of the parent application), and (c) any patents issuing on said applications including reissues,
reexaminations and extensions; and any corresponding foreign applications or patents. Under such UCSD License Agreements, Buyer
and Seller have separately agreed to reimburse the University for certain Patent Costs and have been granted certain rights with
respect to the infringement and defense of Patent Rights. This Section ‎4 is intended
to set forth each Party’s rights and obligations as between Buyer and Seller, with respect to the matters described in the
foregoing sentence. The Parties acknowledge that nothing in this Agreement is intended to affect or limit the rights of the University
under the UCSD License Agreements.



 




    	 	10	 



     


    

 


		4.3	Maintenance Fees. As between Buyer and Seller:



 


		(a)	Seller shall be responsible for any and all out-of-pocket expenses for the maintenance of all patents
filed in the Licensed Territory (as defined in Section ‎1.1(b) of this Agreement) included
in the Patent Rights, and Seller shall ensure that all such expenses are reimbursed to the University in accordance with the terms
of its UCSD License Agreement;



 


		(b)	Buyer shall be responsible for any and all out-of-pocket expenses for the maintenance of all patents
filed in the Territory (as defined in the APA) included in the Patent Rights, and Buyer shall ensure that all such expenses are
reimbursed to the University in accordance with the terms of its UCSD License Agreement; and



 


		(c)	any other Patent Costs that are required to be reimbursed under the UCSD License Agreement shall
be allocated between the Parties in accordance with a written amendment to this Agreement executed by both Parties.



 


		4.4	Enforcement and Defense of UCSD Patents. Each Party may exercise its rights and fulfill
its obligations with respect to the infringement, enforcement and defense of any Patent Rights (including with respect to Invalidity
Actions relating to the Patent Rights) in accordance with its respective UCSD License Agreement, and without any obligation to
the other Party except as set forth in this Section ‎4.4. Seller may not defend or enforce
any Patent Rights under its UCSD License Agreement (including but not limited to the defense of Invalidity Actions), except with
the prior written consent of Buyer, which shall not be unreasonably withheld or delayed. In the event Buyer provides Seller with
written consent to defend or enforce any such Patent Rights and Seller is permitted to defend or enforce the Patent Rights under
its UCSD License Agreement, Seller shall defend or enforce the Patent Rights at Seller’s sole cost and expense, shall keep
Buyer reasonably informed regarding matters related to its activities under this Section ‎4.4
and shall, without limitation:



 


		(a)	provide (or direct its external counsel to provide) Buyer with access to copies of all material
documentation and correspondence relating to the defense and enforcement so that Buyer may remain informed with respect thereto;



 


		(b)	give Buyer reasonable opportunity to consult with Seller (or its external counsel) regarding such
defense and enforcement and to comment on all relevant material matters related to defense and enforcement of the Licensed IP (particularly
but not limited to such matters that may affect the Business or the Business Product) and provide input on strategy, filings and
selection and use of outside counsel; and



 




    	 	11	 



     


    

 


		(c)	ensure that all comments by Buyer are reasonably considered by Seller and its counsel and shall
implement any and all comments by Buyer which relate to the Business or the Business Product.



 


		4.5	If permitted by the University, Buyer may voluntarily join Seller in the suit initiated by Seller
with counsel of Buyer’s choice at Buyer’s sole cost. If necessary to maintain a lawsuit initiated by Seller, Buyer
will, at Seller’s sole cost, join Seller in any infringement suit necessary to enforce Seller’s rights. Notwithstanding
anything in the foregoing, Seller shall not waive, release, settle or compromise any such claim or make any admission as to Buyer
or Buyer’s Affiliates, without the prior written approval of Buyer, which shall not be unreasonably withheld or delayed.



 


		5.	Term And Termination



 


		5.1	Term. The term of the Agreement shall commence as of the Effective Date and shall continue
perpetually unless terminated in accordance with Section ‎5.2 or ‎5.3.



 


		5.2	Termination by Buyer. Without limiting any other rights or remedies that may be available
to Buyer, Buyer may terminate this Agreement upon written notice to Seller if Seller or any of its Affiliates, or any other Person
acting under direction of Seller or any such Affiliate, directly or indirectly, files or takes any action to challenge any of Buyer’s
or its Affiliate’s rights in the Licensed IP or any University-owned patent licensed under the UCSD License Agreements in
the Territory, and Seller fails to reverse and cure the challenge to Buyer’s reasonable satisfaction within 30 days of Buyer’s
notice to Seller (or if such reversal and cure cannot reasonably be accomplished within such original 30-day period, and Seller
notifies Buyer in writing within such 30-day period of Seller’s intention and proposed steps to reverse and cure and thereafter
diligently pursues the same, then Seller will have such additional period of time (not to exceed 60 days following expiration of
the original 30-day period) as is necessary to accomplish such reversal and cure).



 


		5.3	Termination by Seller. Seller may terminate this Agreement upon at least 90 days’
written notice to Buyer, provided that such notice shall state Seller’s reason for terminating this Agreement.



 


		5.4	Effect of Termination. Upon termination of this Agreement for any reason:



 


		(a)	neither Party’s obligation or liability accrued or any rights arising under this Agreement
prior to such termination shall be impaired or affected;



 


		(b)	Seller’s rights to the Licensed IP shall immediately cease;



 


		(c)	at Buyer’s option, Seller shall destroy or deliver to Buyer any of Buyer’s Confidential
Information in Seller’s or its Sublicensees’ possession or control, including written and electronic records (and copies
thereof) that contain Confidential Information of Buyer or the Licensed IP and materials that are based on or use or incorporate
any Confidential Information of Buyer or the Licensed IP, and certify to Buyer that it has complied with this Section ‎5.4(c);
and



 




    	 	12	 



     


    

 


		(d)	Sections ‎1.2, ‎1.3(b),
‎1.3(d), ‎1.7, ‎1.8,
‎2.1, ‎2.2 and ‎4
to ‎8 (inclusive) shall survive any termination of this Agreement.



 


		6.	Confidentiality



 


		6.1	Definition. “Confidential Information” means any and all non public
information or other confidential or proprietary information disclosed by or on behalf of Buyer to Seller, whether orally or in
writing, that is either: (a) conspicuously marked or otherwise identified as confidential or proprietary at the time of disclosure;
or (b) should reasonably be understood by Seller to be confidential based upon the nature of the information disclosed or the circumstances
of the disclosure. Confidential Information includes the Licensed IP.



 


		6.2	Nonuse and Nondisclosure. Seller shall not: (a) use any Confidential Information other than
for the purpose of exercising its rights under the License Grant; or (b) disclose any Confidential Information to any third party.
Seller shall take all reasonable precautions to prevent any unauthorized disclosure of Confidential Information, at least by exercising
no less than the same degree of care as Seller exercises with respect its own proprietary and confidential information. If Seller
receives a subpoena or other validly issued administrative or judicial process requesting Confidential Information, it will, to
the extent legally permissible, promptly notify Buyer, and provide reasonable assistance to Buyer to object to, oppose, squash
or otherwise limit the subpoena or process.



 


		7.	Liability



 


		7.1	Disclaimer. SELLER ACKNOWLEDGES AND AGREES THAT THE LICENSED IP IS LICENSED “AS IS”
WITHOUT ANY WARRANTY, EXPRESS OR IMPLIED. BUYER DISCLAIMS AND SHALL NOT BE LIABLE FOR ANY WARRANTIES, REPRESENTATIONS, GUARANTEES,
COVENANTS AND OBLIGATIONS OF ANY KIND OR NATURE, WHETHER EXPRESS OR IMPLIED, INCLUDING THOSE RELATING TO THE USEFULNESS, MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, VALIDITY, PERFORMANCE, MARKETABILITY OR TITLE OF THE LICENSED IP OR SELLER’S
EXERCISE OF ITS RIGHTS UNDER THIS AGREEMENT. SELLER ASSUMES THE ENTIRE RISK AND RESPONSIBILITY FOR THE SAFETY, EFFICACY, PERFORMANCE,
DESIGN, MARKETABILITY, TITLE, AND QUALITY OF ALL PRODUCTS WHICH PRACTICE OR USE THE LICENSED IP (OTHER THAN ANY PRODUCTS OF BUYER
OR BUYER’S OTHER LICENSEES OR ANY USE OF THE LICENSED IP BY BUYER OR ITS OTHER LICENSEES). Seller hereby covenants not to
sue Buyer or its Affiliates with respect to any of the matters which are disclaimed by Buyer in this Section ‎7.1.



 




    	 	13	 



     


    

 


		7.2	Limitation of Liability. In no event shall Buyer or its Affiliates be responsible or liable
for any indirect, special, punitive, incidental, or consequential damages or lost profits, lost business, lost reputation, lost
opportunity, or intellectual property infringement to Seller, regardless of legal theory.



 


		7.3	Application. The disclaimers and limitations in this Section ‎7
apply even though Buyer or its Affiliates may have been advised of the possibility of the relevant loss or damage.



 


		7.4	Indemnification. Seller shall, and will require its Sublicensees (including distributors)
to, indemnify, hold harmless, and defend Buyer and its Affiliates, and each of their officers, employees, sublicensees, distributors,
customers, representatives and agents, against any and all claims, suits, losses, damages, costs, fees, and expenses, including
any indirect, special, punitive, incidental, or consequential damages, and any profits, lost business or lost opportunity, regardless
of legal theory, in connection with: (a) Seller’s exercise of its rights under this Agreement; (b) the New Products or Ex-America
Products; (c) Seller’s breach of this Agreement; or (d) any act or omission by Seller, any Licensed Distributor or any Person
acting under Seller’s control that results in: (i) a material reduction of Buyer’s ability to use, design, develop,
manufacture, use, import, export, offer for sale, sell, license, reproduce, distribute, or otherwise exploit or commercialize any
Business Product; (ii) the withdrawal or any adverse effect on any IND, NDA, clinical trial or other product registration; (iii)
Buyer or its Subsidiaries to be in breach or violation of any condition under any IND, NDA, clinical trial or other product registration
or any Laws applicable to the Business Product; or (iv) any Governmental Authority commencing or threatening an investigation,
audit, Action, suit, hearing, charge, claim, demand, notice or other proceeding (each, an “Indemnified Claim”).
Nothing is indemnified if Seller is merely providing a regulatory agency with information regarding an adverse event. Without limiting
the foregoing obligations of Seller, where an Indemnified Claim is asserted by a third party, Buyer will have the right at its
option, to have sole control over the defense, settlement, compromise, admission, or acknowledgment of the Indemnified Claim, or
to request that Seller undertake the defense, settlement, compromise, admission, or acknowledgment of the Indemnified Claim. If
Buyer notifies Seller that Buyer shall have sole control over the defense, settlement, compromise, admission, or acknowledgment
of the Indemnified Claim, Seller shall at Seller’s own cost and expense, provide all assistance as requested by Buyer. If
Buyer requests that Seller undertakes the defense, settlement, compromise, admission, or acknowledgment of the Indemnified Claim,
Seller shall immediately comply with such request, keep Seller reasonably informed of the progress of the Indemnified Claim (including
providing all information as requested by Buyer) and allow Buyer to reasonably participate, at Buyer’s sole cost and expense,
in such defense, settlement, compromise, admission, or acknowledgment using counsel of Buyer’s choice. Notwithstanding anything
in the foregoing, Seller shall not waive, release, compromise or settle any Indemnified Claim that may adversely affect Buyer in
any manner, without Buyer’s prior written approval.

		8.	Miscellaneous



 


		8.1	Compliance with Laws. Seller shall comply with all Legal Requirements, including all applicable
United States and foreign laws with respect to the transfer of New Products and Ex-America Products and related technical data
to foreign countries, including the International Traffic in Arms Regulations and the Export Administration Regulations, in the
exercise of its rights and fulfillment of its obligations under this Agreement.



 


		8.2	Right to Injunction. Seller acknowledges that the Licensed IP possesses special, unique
and extraordinary characteristics which could make difficult the assessment of monetary damages, which Buyer could sustain due
to a breach or threatened breach by Seller of this Agreement, such as Seller’s unauthorized use of the Licensed IP or the
Confidential Information. Seller recognizes and acknowledges that such unauthorized activities or breaches of obligations could
cause irreparable injury to Buyer and specifically agrees that injunctive and other equitable relief is appropriate in the event
of a breach or threatened breach by Seller of this Agreement. Such equitable relief shall not be exclusive of or in lieu of any
other remedies available to Buyer. Buyer’s pursuit of equitable remedies hereunder shall not be deemed to be an election
of remedies by Buyer. Seller agrees to waive any requirement for the security or posting of any bond in connection with such remedy.



 


		8.3	Entire Agreement. This Agreement together with the Transaction Documents constitutes the
entire agreement between Seller and Buyer in relation to the subject matter set forth herein. Any prior agreements, letters of
intent, term sheets or understandings among Seller and Buyer, and any representations or statements made by or on behalf of Buyer
or any of its Affiliates to Seller, whether written or oral, with respect to the subject matter of this Agreement are superseded
to the extent not expressly included in this Agreement or the APA.



 


		8.4	Assignment. Seller shall not assign, transfer, or delegate any of its obligations under
this Agreement, in whole or in part, without Buyer’s prior written consent. Any attempt to assign, transfer, or delegate
in breach of the foregoing assignment shall be null and void and of no force or effect. Buyer may assign this Agreement at any
time and Seller hereby agrees to any such assignment.



 


		8.5	Counterparts. This Agreement may be executed in multiple counterparts and by facsimile or
other means of electronically imaging a signature, each of which, when taken together, shall constitute one and the same instrument.



 


		8.6	Relationship of Parties. The Parties are independent contractors. There is no relationship
of principal to agent, master to servant, employer to employee, or franchiser to franchisee between the Parties. Neither Party
has the authority to bind the other or incur any obligation on its behalf.

Exhibit E


 


Form of Transition Services Agreement


  


This TRANSITION SERVICES
AGREEMENT (“Agreement”), is made as of [●], 2016, by and between Navidea Biopharmaceuticals, Inc., a Delaware
corporation (the “Seller”), and Cardinal Health 414, LLC, a Delaware limited liability company (“Buyer”).
Buyer and Seller are each referred to herein as a “Party” and, collectively, as the “Parties.”


 


RECITALS


 


A.           Buyer
and Seller are parties to that certain Asset Purchase Agreement, dated as of November 23, 2016 (the “Asset Purchase Agreement”),
pursuant to which Buyer agreed to acquire from Seller, and Seller agreed to sell, assign, convey and transfer to Buyer, certain
assets and liabilities associated with the Business in the Territory. Capitalized terms used but not otherwise defined herein shall
have the meanings ascribed to such terms in the Asset Purchase Agreement.


 


B.           In
connection with the transactions contemplated by the Asset Purchase Agreement, Buyer and Seller desire to enter into an arrangement
whereby Seller will provide certain Services (as defined below) to Buyer in connection with the Business, all pursuant to the terms
and conditions set forth in this Agreement.


 


C.           This
Agreement is being executed and delivered by Buyer and Seller concurrently with the Closing under the Asset Purchase Agreement,
as contemplated by Section 2.9 thereof.


 


NOW, THEREFORE, in
consideration of the mutual benefits to be derived from this Agreement (as well as the Asset Purchase Agreement) and of the representations,
warranties, conditions, agreements and promises contained herein and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the Parties hereto, intending to be legally bound, agree as follows:


 


AGREEMENT


 


1.          Services.


 


(a)          During
the Transition Period, Seller agrees to provide, or to cause its Affiliates to provide, to Buyer or any Affiliate of Buyer the
following services (collectively, the “Services”): (i) the services, including access to records, information,
systems and personnel, as described on Exhibit A for the respective service periods specified on Exhibit A; and (ii)
such other services, including access to records, information, systems and personnel, as may be requested by Buyer or any Affiliate
of Buyer from time to time with respect to (A) any Product Registrations or other approvals, licenses or registrations of the Business
Product in the Territory or (B) any Payment Claims (as defined below).


 




     


     


    

 


(b)          From
time to time during the Transition Period, Buyer may identify additional services that (i) were performed by Seller in connection
with the Business immediately prior to the Closing Date or (ii) are necessary for the operation of the Business or otherwise to
effectuate an orderly transition of the Business to Buyer, in each case, that were inadvertently omitted from the original Services
(collectively, the “Additional Services”). Except as set forth in the next sentence, the Parties shall amend
Exhibit A to include a description of any such Additional Service requested by Buyer, the time period during which the Additional
Service will be provided and any other terms applicable thereto, and such Additional Services will thereafter constitute “Services”
to be provided by Seller in accordance with the terms of this Agreement. If Seller reasonably believes the performance of any Additional
Service requested by Buyer pursuant to this Section 1(b) will significantly disrupt its operations, then Buyer and Seller
shall negotiate in good faith to establish terms under which Seller can provide such Additional Services, but Seller will not be
obligated to provide such Additional Service if following such good faith negotiations, the Parties are unable to reach agreement
on the terms of such Additional Service.


 


(c)          Standard
of Service. Seller shall (or shall cause one or more of its Affiliates to) perform the Services in accordance with Buyer’s
reasonable instructions, timelines and guidelines and in substantially the same manner, and with at least the same level of care
and effort as the same or similar services were provided by Seller and its Affiliates in respect of the Business pursuant to Seller’s
historical practices in operating the Business, including with respect to manner, amount, timeliness, priority and quality. In
any event, Seller (or its Affiliates) will perform the Services with no less than a commercially reasonable level of care and effort
and in accordance with all applicable Legal Requirements.


 


(d)          Subcontractors.
Seller may provide any or all of the Services through or with the assistance of one or more third-party subcontractors; provided
that, if such subcontractor has not been engaged by Seller with respect to such Service in connection with the Business for the
12 consecutive months prior to the date hereof, Seller shall obtain the prior written consent of Buyer, which may be withheld in
Buyer’s sole discretion, to hire such subcontractor. Seller will remain responsible, and will be liable, for the Services
performed by any subcontractors. Seller will be Buyer’s sole point of contact regarding the Services, including with respect
to payment.


 


2.          Term
of Agreement; Extension.


 


(a)          Term.
The term of this Agreement (the “Transition Period”) shall commence on the Closing Date and, unless extended
pursuant to Section 2(b) or by the mutual written agreement of the Parties, shall terminate on the later of (i) the date
upon which Seller’s obligation to provide Services according to Exhibit A (as amended) expires such that Seller has
no continuing obligation to perform any Services hereunder and (ii) eighteen (18) months after the date of this Agreement. Buyer
may, in its sole discretion, terminate any category of Services upon thirty (30) days prior written notice to Seller, which notice
shall specify the Services(s) to be terminated and the date of termination.


 


(b)          Option
to Extend Service Term. Upon written request from Buyer delivered to Seller no later than thirty (30) days prior to the expiration
date for any category of Services set forth in Exhibit A, the Parties will amend Exhibit A with respect to such Service
to extend the term of such Service for up to thirty (30) days (or for such other period negotiated in good faith by the Parties
and set forth in such amendment to Exhibit A with respect to such Service), on the terms and conditions contained in this
Agreement.


 




    	 	-2-	 



     


    

 


3.          Consideration;
Expenses.


 


(a)          Consideration.
The Parties acknowledge and agree that the Services will be provided in consideration of the Purchase Price paid by Buyer to Seller
pursuant to the Asset Purchase Agreement, and that no additional fees will be charged to Buyer in respect of the Services.


 


(b)          Expenses.
Seller, on behalf of itself and its Affiliates, will obtain Buyer’s prior written approval, not to be unreasonably withheld,
conditioned or delayed, prior to incurring any out-of-pocket expenses in connection with providing the Services. In the event that
Seller or any of its Affiliates incurs reasonable and documented out-of-pocket expenses in connection with the provision of any
Service after Buyer’s approval in accordance with the preceding sentence (“Expenses”), Buyer shall reimburse
Seller for all such Expenses in accordance with Section 3(c). For the avoidance of doubt, the Expenses will not include
payment of any wages, bonuses, commissions, employee benefits, including severance and worker’s compensation, or any other
payments made to employees of Seller or its Affiliates (other than reimbursement of items otherwise constituting Expenses).


 


(c)          Invoices.
Seller shall provide Buyer with monthly invoices within fifteen (15) days following the end of each month during the Transition
Period, which shall set forth in reasonable detail and with such supporting documentation as Buyer may reasonably request, the
Expenses. Within thirty (30) days after receipt of the invoice from Seller, Buyer will pay any undisputed Expenses. In the event
of an invoice dispute, Buyer shall deliver a written statement to Seller no later than ten (10) days prior to the date payment
is due listing all disputed items and providing a reasonably detailed description of each disputed item. The Parties will work
in good faith to promptly resolve any such disputes. Seller shall continue performing the Services pending resolution of any dispute.


 


4.          Termination.


 


(a)          Termination
Rights. In addition to, and not in limitation of, any other termination rights set forth in this Agreement, this Agreement
may be terminated (i) by the mutual written consent of the Parties; (ii) by either Party, by giving written notice to the other
Party, if the other Party commits a material breach of this Agreement, which breach is not cured within thirty (30) days after
receipt of such notice of the breach; or (iii) by either Party if the other Party (A) files for bankruptcy, (B) becomes or is declared
insolvent, or is the subject of any proceedings (not dismissed within sixty (60) days) related to its liquidation, insolvency or
the appointment of a receiver, (C) makes an assignment for the benefit any of its creditors, or (D) takes any corporate action
for its winding up or dissolution. For the avoidance of doubt, any non-payment by Buyer of any Expenses it is disputing in good
faith by the applicable due date will not be deemed to be a material breach of this Agreement.


 


(b)          Effect
of Termination. Upon termination of this Agreement in its entirety pursuant to Section 4(a), all obligations of the
Parties hereto shall terminate, except for the provisions of Sections 4(c), 5, 6 and 8.


 




    	 	-3-	 



     


    

 


(c)          Rights
Upon Termination or Expiration. If Buyer terminates this Agreement pursuant to Section 4(a), then Seller will provide
Buyer with reasonable information and assistance to facilitate the transition responsibility for the Services from Seller to Buyer
or its designee.


 


5.          Confidentiality.
The Parties recognize that, in connection with provision of the Services, the Parties and their Affiliates may have access to confidential
business information, proprietary information, and trade secrets of the other Party or its Affiliates. Each Party acknowledges
that such information is valuable, and that disclosure to, or use for the benefit of, any Person could cause substantial damage
to the other Party. The Parties will, and will cause their respective Affiliates and Representatives to, at all times maintain
the confidentiality of the other Party’s Confidential Information, and the Parties will not, and will cause their respective
Affiliates and Representatives to, disclose any such information to any Person, nor will the Parties or their respective Affiliates
or Representatives use any of the other Party’s Confidential Information for any purpose other than provision of the Services
hereunder. Each Party’s duty of confidentiality with regard to the other Party’s Confidential Information will not
extend to: (i) any information that, at the time of disclosure, had been previously published and was part of the public domain;
or (ii) information that is published after disclosure, unless such publication is a breach of this Agreement by such Person or
any other obligation of confidentiality.


 


6.          Intentionally
Omitted.


 


7.          Additional
Agreements.


 


(a)          Compliance
with Laws. Each Party will, and will cause its respective employees and subcontractors to, comply in all material respects
with all applicable Legal Requirements in the performance of the Services and its other obligations under this Agreement.


 


(b)          Cooperation.
Each Party will, and will cause its respective Affiliates and Representatives to, cooperate with the other in good faith and will
take such other actions as may be reasonably requested from time to time by the other as are necessary to accomplish the intended
purpose of this Agreement and to resolve in a commercially reasonable manner any problems that may occur in relation to it. In
furtherance of the foregoing, each Party will, upon the other Party’s reasonable request and subject to applicable Legal
Requirement, provide the other Party with any information owned or controlled by it that is reasonably required for the other Party
to fulfill its obligations or exercise its rights under this Agreement.


 


(c)          Required
Consents. If any consent, waiver, approval, license, Order or other authorization (“Authorization”) is required
in connection with performing the Services, Seller or one of its Affiliates shall obtain and maintain in full force and effect
such Authorization for the duration of the Transition Period.


 


(d)          Records;
Access. During the Transition Period, Seller will keep and maintain complete and accurate written and electronic records and
accounts relating to its performance of the Services and performance of its obligations under this Agreement. Buyer or its designee
will, at no cost to Buyer, have the right, upon reasonable advance notice and during normal business hours, to audit and inspect
Seller’s books and records relating to the Services and the performance of Seller’s obligations under this Agreement.


 




    	 	-4-	 



     


    

 


(e)          Regulatory
Review. Each Party will notify the other promptly of any formal request or Order by a Governmental Authority to examine records
regarding Buyer that are maintained by Seller or to examine Seller’s performance of the Services. Each Party will cooperate
reasonably with the other Party in connection with any such examination.


 


(f)          Operation
of Business. Notwithstanding anything to the contrary in this Agreement, including Exhibit A, following the Closing
Date, Buyer shall have the sole right to operate the Business, Acquired Assets and Assumed Liabilities as it deems appropriate
in its sole discretion, including changing the price, marketing strategy, distribution channel or manufacturing, packaging or testing
arrangements with respect to the Business Product.


 


(g)          NDC

Exhibit F


 


Form of Warrant




 


NEITHER THIS WARRANT NOR THE SECURITIES ISSUABLE UPON EXERCISE
OF THIS WARRANT HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. SUBJECT TO SECTION 6 BELOW, AND EXCEPT IN COMPLIANCE
WITH RULE 144 UNDER SAID ACT, NO SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO
OR AN OPINION OF COUNSEL FOR HOLDER, SATISFACTORY TO COMPANY, THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT OR RECEIPT OF
A NO-ACTION LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION.


 


WARRANT TO PURCHASE SHARES OF COMMON
STOCK


 


[_____], 2016


 


THIS CERTIFIES THAT, for value received,
Cardinal Health 414, LLC, a Delaware limited liability company (“Holder”), is entitled to subscribe for and
purchase TEN MILLION (10,000,000) shares of fully paid and nonassessable shares of Common Stock of NAVIDEA BIOPHARMACEUTICALS,
INC., a Delaware corporation (“Company”), at the Warrant Price (as hereinafter defined), subject to the provisions
and upon the terms and conditions hereinafter set forth. As used herein, the term “Common Stock” shall mean
Company’s presently authorized common stock, $0.001 par value per share, and any stock into which such Common Stock may hereafter
be converted or exchanged and the term “Warrant Shares” shall mean the shares of Common Stock which Holder may
acquire pursuant to this Warrant and any other shares of stock into which such shares of Common Stock may hereafter be converted
or exchanged. This Warrant is being executed and delivered pursuant to the terms of an Asset Purchase Agreement, dated November
23, 2016, between Holder and the Company (the “Purchase Agreement”). Capitalized terms not otherwise defined
herein shall have the respective meanings ascribed to them in the Purchase Agreement.


 


Section 1.          Warrant
Price. The “Warrant Price” shall initially be one and 50/100 dollars ($1.50) per share, subject to adjustment
as provided in Section 7 below.


 


Section 2.          Conditions
to Exercise. The purchase right represented by this Warrant may be exercised at any time, or from time to time, in whole or
in part, during the term commencing on the date hereof and ending at 5:00 p.m. (New York City time) on the fifth anniversary of
the date of this Warrant (the “Expiration Date”).


 


Section 3.          Method
of Exercise or Conversion; Payment; Issuance of Shares; Issuance of New Warrant.


 




     


     


    

  


(a)          Cash
Exercise. Subject to Section 2 hereof, the purchase right represented by this Warrant may be exercised by Holder, in whole
or in part, by delivery (pursuant to Section 17) to the Company of a duly executed Notice of Exercise in substantially the form
attached hereto, provided that, within three (3) trading days following the date of such exercise, Holder shall surrender
the original of this Warrant and pay to the Company, by certified or bank check, or wire transfer of immediately available funds,
an amount equal to the then applicable Warrant Price per share multiplied by the number of Warrant Shares then being purchased.
In the event of any exercise of the rights represented by this Warrant, certificates for the shares of stock so purchased shall
be in the name of, and delivered to, Holder, or as Holder may direct (subject to the terms of transfer contained herein and upon
payment by such Holder of any applicable transfer taxes). Such delivery shall be made within 10 trading days after exercise of
this Warrant and at the Company’s expense and, unless this Warrant has been fully exercised or expired, a new Warrant having
terms and conditions substantially identical to this Warrant and representing the portion of the Warrant Shares, if any, with respect
to which this Warrant shall not have been exercised, shall also be issued to Holder within 10 days after exercise of this Warrant.
The Warrant Shares shall be deemed to have been issued and Holder or its designee shall be deemed to have become a holder of record
of such Warrant Shares for all purposes as of the date the Notice of Exercise of this Warrant is delivered to the Company.


 


(b)          Limited
Conversion Rights. If, at the time of delivery (pursuant to Section 17) to the Company of a duly executed Notice of Exercise
in substantially the form attached hereto, a registration statement (or prospectus) filed by the Company with the U.S. Securities
and Exchange Commission with respect to the resale by Holder of the Warrant Shares (the “Registration Statement”)
is not effective under the Securities Act of 1933, as amended (the “Act”), and the rules and regulations promulgated
thereunder, then in lieu of exercising this Warrant as specified in Section 3(a), Holder may convert this Warrant, in whole or
in part, into Warrant Shares by surrender of the original of this Warrant (together with a duly executed Notice of Exercise in
substantially the form attached hereto) at the principal office of the Company, in which even the Company shall issue to Holder
the number of Warrant Shares computed using the following formula:


 


X = Y(A-B)/A


 


Where:


 


X = the number of Warrant Shares
to be issued to Holder;


 


Y = the number of Warrant Shares
requested to be purchased under this Warrant (at the date of such calculation);


 


A = the Fair Market Value of one share of the Company’s
Common Stock (at the date of such calculation); and


 


B = the Warrant Price (as adjusted to the date of such
calculation).


 


(c)          Fair
Market Value. For purposes of this Section 3, Fair Market Value of one share of the Company’s Common Stock shall mean:


 


(i)          The
last reported sale price quoted on the NYSE MKT or on any other exchange on which the Common Stock is listed, or the average of
the closing bid and asked prices of Common Stock quoted in the Over-The-Counter Market Summary, whichever is applicable, as published
in the Eastern Edition of the Wall Street Journal for the three (3) trading days prior to the date of determination of the Fair
Market Value; or


 




    	 	-2-	 



     


    

  


(ii)         In
the event of an exercise in connection with a merger, acquisition or other consolidation in which the Company is not the surviving
entity, the value to be received per share of Common Stock by all holders of the Common Stock in such transaction as determined
in the reasonable good faith judgment of the Company’s Board of Directors; or


 


(iii)        In
any other instance, the value as determined in the reasonable good faith judgment of the Company’s Board of Directors.


 


In the event of Section 3(c)(ii) or 3(c)(iii) above, the Company’s
Board of Directors shall prepare a certificate, to be signed by an authorized officer of the Company, setting forth in reasonable
detail the basis for and method of determination of the per share Fair Market Value of the Common Stock. The Board of Directors
will also certify to Holder that this per share Fair Market Value will be applicable to all holders of Company’s Common Stock.
Such certifications must be made to Holder, in the event of Section 3(c)(ii) above, at least ten (10) business days prior to the
proposed effective date of the merger, acquisition or other consolidation, and in the event of Section 3(c)(iii), promptly after
exercise of this Warrant.


 


(d)          Automatic
Exercise. To the extent this Warrant is not previously exercised, it shall be deemed to have been automatically converted in
accordance with Sections 3(b) and 3(c) hereof (even if not surrendered) as of immediately before its expiration, involuntary termination
or cancellation if the Registration Statement is not effective as of such time (including, without limitation, pursuant to Section
3(e)(ii)) if the then-Fair Market Value of a Warrant Share exceeds the then-Warrant Price, unless Holder notifies the Company in
writing to the contrary prior to such automatic exercise.


 


(e)          Treatment
of Warrant Upon Acquisition of the Company.


 


(i)         Certain Definitions; Acquisitions.
For the purpose of this Warrant: “Acquisition” means, whether direct or indirect and whether in one or a series
of related transactions, any sale, license, assignment, or other disposition of all or substantially all of the assets of the
Company, or any reorganization, consolidation, or merger of the Company, or sale of outstanding Company securities by holders
thereof, where the holders of the Company’s securities as of immediately before the transaction beneficially own less than
a majority of the outstanding voting securities of the successor or surviving entity as of immediately after the transaction (or,
if the successor or surviving entity is a wholly-owned subsidiary of another corporation, such successor or surviving entity’s
parent). For purposes of this Section 3(e), “Affiliate” shall mean any person or entity that owns or controls
directly or indirectly ten percent (10%) or more of the voting capital stock of the Company, any person or entity that controls
or is controlled by or is under common control with such persons or entities, and each of such person’s or entity’s
officers, directors, joint venturers or partners, as applicable. The Company shall provide Holder with written notice of any proposed
Acquisition not later than ten (10) Business Days prior to the closing thereof setting forth the material terms and conditions
thereof, and shall provide Holder with copies of the draft transaction agreements and other documents in connection therewith
and with such other information respecting such proposed Acquisition as may reasonably be requested by Holder. If the Acquisition
described in such notice is terminated or abandoned prior to the consummation thereof, the Company shall provide prompt notice
thereof to Holder and, unless Holder advises the Company in a written notice that it elects to reaffirm the exercise, any purported
exercise of this Warrant in connection with such proposed Acquisition shall be null and void. For the avoidance of doubt, the
transactions contemplated by the Purchase Agreement do not constitute an Acquisition for purposes of this Warrant.


 




    	 	-3-	 



     


    

  


(ii)         Acquisition
for Cash. Holder agrees that, in the event of an Acquisition in which the sole consideration is cash, and such consideration
is to be received by the holders of the Company’s Common Stock in respect of their shares of the Common Stock at the closing
of the Acquisition, this Warrant shall be automatically exercised (or terminated) as provided in Section 3(d) (even if a Registration
Statement has been declared and remains effective by the SEC) on and as of the closing of such Acquisition to the extent not previously
exercised.


 


(iii)        Asset
Sale. In the event of an Acquisition that is an arm’s length sale of all or substantially all of the Company’s
assets (and only its assets) to a third party that is not an Affiliate of the Company (a “True Asset Sale”),
Holder may either (A) exercise its conversion or purchase right under this Warrant pursuant to Sections 3(a) or 3(b) (even if a
Registration Statement has been declared and remains effective by the SEC), respectively, and such exercise will be deemed effective
immediately prior to the consummation of such Acquisition, or (B) permit the Warrant to continue until the Expiration Date if the
Company continues as a going concern following the closing of any such True Asset Sale. For the avoidance of doubt, the transactions
contemplated by the Purchase Agreement do not constitute a True Asset Sale for purposes of this Warrant.


 


(iv)        Assumption
of Warrant. Upon the closing of any Acquisition other than as particularly described in Section 3(e)(ii) or 3(e)(iii) above
(and, for the avoidance of doubt, including any such Acquisition in which the Company is not the surviving entity), the Company
shall, unless Holder requests otherwise, cause the surviving or successor entity to assume this Warrant and the obligations of
the Company hereunder, and this Warrant shall, from and after such closing, be exercisable for the same class, number and kind
of securities, cash and other property as would have been paid for or in respect of the shares issuable (as of immediately prior
to such closing) upon exercise in full hereof as if such shares had been issued and outstanding on and as of such closing, at an
aggregate Warrant Price equal to the aggregate Warrant Price in effect as of immediately prior to such closing (and subject to
further adjustment thereafter from time to time in accordance with the provisions of this Warrant).


 


(v)         Conditional
Exercise. Notwithstanding any other provision hereof, if an exercise of this Warrant is to be made in connection with an Acquisition,
such exercise may at the election of Holder be conditioned upon the consummation of such Acquisition, in which case such exercise
shall not be deemed to be effective until immediately prior to the consummation of the Acquisition.


 


Section 4.              Representations
and Warranties of Holder and the Company.


 


(a)          Representations
and Warranties of Holder. Holder represents and warrants to the Company as of the date hereof with respect to this Warrant
as follows:


 




    	 	-4-	 



     


    

  


(i)          Evaluation.
Holder has substantial experience in evaluating and investing in private placement transactions of securities of companies similar
to the Company so that Holder is capable of evaluating the merits and risks of its investment in the Company and has the capacity
to protect its interests.


 


(ii)         Resale.
Except for transfers to an affiliate of Holder, Holder is acquiring this Warrant and the Warrant Shares issuable upon exercise
of this Warrant (collectively, the “Securities”) for investment for its own account and not with a view to,
or for resale in connection with, any distribution thereof. Holder understands that the Securities have not been registered under
the Act by reason of a specific exemption from the registration provisions of the Act which depends upon, among other things, the
bona fide nature of the investment intent as expressed herein.


 


(iii)        Rule
144. Holder acknowledges that the Securities must be held indefinitely unless subsequently registered under the Act or an exemption
from such registration is available. Holder is aware of the provisions of Rule 144 promulgated under the Act.


 


(iv)        Accredited
Investor. Holder is an “accredited investor” within the meaning of Regulation D promulgated under the Act.


 


(b)          Representations
and Warranties by the Company. The Company hereby represents and warrants to Holder that the statements in the following paragraphs
of this Section 4(b) are true and correct as of the date hereof.

Organization and Authority. The Company (A) is a corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, (B) has the corporate power and authority to own and operate its properties and to
carry on its business as now conducted and as proposed to be conducted, and (C) is qualified as a foreign corporation in all jurisdictions
where such qualification is required.


 


(ii)         Corporate
Power. The Company has all requisite legal and corporate power and authority to execute, issue and deliver this Warrant, to
issue the Warrant Shares issuable upon exercise or conversion of this Warrant, and to carry out and perform its obligations under
this Warrant and any related agreements.


 


(iii)        Authorization;
Enforceability. All corporate action on the part of the Company, its officers, directors and shareholders necessary for the
authorization, execution, delivery and performance of its obligations under this Warrant and for the authorization, issuance and
delivery of this Warrant and the Warrant Shares issuable upon exercise of this Warrant has been taken and this Warrant constitutes
the legally binding and valid obligation of the Company enforceable in accordance with its terms.


 




    	 	-5-	 



     


    

  


(iv)        Valid
Issuance of Warrant and Warrant Shares. This Warrant has been validly issued and is free of restrictions on transfer other
than restrictions on transfer set forth herein and under applicable state and federal securities laws. The Warrant Shares issuable
upon exercise or conversion of this Warrant, when issued, sold and delivered in accordance with the terms of this Warrant for the
consideration expressed herein, will be duly and validly issued, fully paid and nonassessable, and will be free of restrictions
on transfer other than restrictions under this Warrant and under applicable state and federal securities laws. Subject to applicable
restrictions on transfer, the issuance and delivery of this Warrant and the Warrant Shares issuable upon exercise or conversion
of this Warrant are not subject to any preemptive or other similar rights or any liens or encumbrances except as specifically set
forth in the Company’s Amended and Restated Certificate of Incorporation (“Certificate of Incorporation”)
or this Warrant. Unless a Registration Statement has been declared and remains effective by the SEC at the time of the issuance
of the Warrant Shares, the offer, sale and issuance of the Warrant Shares, as contemplated by this Warrant, are exempt from the
prospectus and registration requirements of applicable United States federal and state security laws, and neither the Company nor
any authorized agent acting on its behalf has taken or will take any action hereafter that would cause the loss of such exemption,
except with respect to filing, causing to become effective, and maintaining the effectiveness of, the Registration Statement.


 


(v)         No
Conflict. The execution, delivery and performance of this Warrant will not (A) contravene any of the organizational documents
of the Company, (B) violate any material Legal Requirement, (C) require any action by, filing, registration, qualification with,
or approval, consent or withholding of objections from, any Governmental Authority or any other Person, except those which have
been obtained and are in full force and effect, (D) result in the creation of any Lien on any of the Company’s Real Property,
or (E) result in any breach of or constitute a default under, or permit the termination or acceleration of, any Material Contract
to which the Company is a party.


 


Section 5.             Legends.


 


(a)          Legend.
Each certificate representing the Warrant Shares shall, unless at the time of issuance the Registration Statement has been declared
and remains effective by the SEC, be endorsed with substantially the following legend:


 


THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933 AND MAY NOT BE TRANSFERRED (UNLESS SUCH TRANSFER IS TO AN AFFILIATE OF HOLDER) UNLESS COVERED BY AN EFFECTIVE
REGISTRATION STATEMENT UNDER SAID ACT, A “NO ACTION” LETTER FROM THE SECURITIES AND EXCHANGE COMMISSION WITH RESPECT
TO SUCH TRANSFER, A TRANSFER MEETING THE REQUIREMENTS OF RULE 144 OF THE SECURITIES ACT OF 1933, OR (IF REASONABLY REQUIRED BY
THE COMPANY) AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY SUCH TRANSFER IS EXEMPT FROM SUCH REGISTRATION.


 


The Company need not enter into its stock records a transfer
of Warrant Shares unless the conditions specified in the foregoing legend are satisfied or the Registration Statement was declared
and remained effective by the SEC at the time of issuance of the Warrant Shares. The Company may also instruct its transfer agent
not to allow the transfer of any of the Warrant Shares unless the conditions specified in the foregoing legend are satisfied or
the Registration Statement was declared and remained effective by the SEC at the time of issuance of the Warrant Shares.


 




    	 	-6-	 



     


    

  


(b)          Removal
of Legend and Transfer Restrictions. The legend relating to the Act endorsed on a certificate pursuant to paragraph 5(a) of
this Warrant shall not be affixed or shall be removed and the Company shall issue a certificate without such legend to Holder if
(i) the Securities are registered under the Act and a prospectus meeting the requirements of Section 10 of the Act is available,
or (ii) Holder provides to the Company an opinion of counsel for Holder reasonably satisfactory to the Company, or other evidence
reasonably satisfactory to the Company, to the effect that public sale, transfer or assignment of the Securities may be made without
registration and without compliance with any restriction such as Rule 144.


 


Section 6.             Transfers
of Warrant. In connection with any transfer by Holder of this Warrant, the Company may require the transferee to provide the
Company with written representations and warranties that transferee is acquiring this Warrant and the Warrant Shares to be issued
upon exercise for investment purposes only and not with a view to any sale or distribution, and may require a legal opinion, in
form and substance satisfactory to the Company and its counsel, stating that such transfer is exempt from the registration and
prospectus delivery requirements of the Act; provided that the Company shall not require an opinion of counsel if the transfer
is to an affiliate of Holder or the Registration Statement has been declared and remains effective by the SEC at the time of such
transfer. Following any transfer of this Warrant, at the request of either the Company or the transferee, the transferee shall
surrender this Warrant to the Company in exchange for a new warrant of like tenor and date, executed by the Company. Upon any partial
transfer, the Company will also execute and deliver to Holder a new warrant of like tenor with respect to the portion of this Warrant
not so transferred. Subject to the foregoing, this Warrant is transferable on the books of the Company at its principal office
by the registered Holder upon surrender of this Warrant properly endorsed.  


 


Section 7.             Adjustment
for Certain Events. The number and kind of securities purchasable upon the exercise of this Warrant and the Warrant Price shall
be subject to adjustment from time to time upon the occurrence of certain events, as follows:


 


(a)          Reclassification
or Merger. In case of (i) any reclassification or change of securities of the class issuable upon exercise of this Warrant
(other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision
or combination), (ii) any merger of the Company with or into another corporation (other than a merger with another corporation
in which the Company is the acquiring and the surviving corporation and which does not result in any reclassification or change
of outstanding securities issuable upon exercise of this Warrant), or (iii) any sale of all or substantially all of the assets
of the Company, the Company, or such successor or purchasing corporation, as the case may be, shall duly execute and deliver to
Holder a new Warrant (in form and substance satisfactory to Holder of this Warrant), or the Company shall make appropriate provision
without the issuance of a new Warrant, so that Holder shall have the right to receive, at a total purchase price not to exceed
that payable upon the exercise of the unexercised portion of this Warrant, and in lieu of the Warrant Shares theretofore issuable
upon exercise or conversion of this Warrant, the kind and amount of shares of stock, other securities, money and property receivable
upon such reclassification, change, merger or sale by a holder of the number of shares of Common Stock then purchasable under this
Warrant, or in the case or such a merger or sale in which the consideration paid consists all or in part of assets other than securities
of the successor or purchasing corporation, at the option of Holder, the securities of the successor or purchasing corporation
having a value at the time of the transaction equivalent to the value of the Warrant Shares purchasable upon exercise of this Warrant
at the time of the transaction. Any new Warrant shall provide for adjustments that shall be as nearly as equivalent as may be practicable
to the adjustments provided for in this Section 7. The provisions of this subparagraph (a) shall similarly apply to successive

(b)          Subdivision
or Combination of Shares. If the Company at any time while this Warrant remains outstanding and unexpired shall subdivide or
combine its outstanding shares of Common Stock, the Warrant Price shall be proportionately decreased and the number of Warrant
Shares issuable hereunder shall be proportionately increased in the case of a subdivision and the Warrant Price shall be proportionately
increased and the number of Warrant Shares issuable hereunder shall be proportionately decreased in the case of a combination.


 


(c)          Stock
Dividends and Other Distributions. If the Company at any time while this Warrant is outstanding and unexpired shall (i) pay
a dividend with respect to Common Stock payable in Common Stock, then the Warrant Price shall be adjusted, from and after the date
of determination of shareholders entitled to receive such dividend or distribution, to that price determined by multiplying the
Warrant Price in effect immediately prior to such date of determination by a fraction (A) the numerator of which shall be the total
number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (B) the denominator of which
shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution; or (ii) make any
other distribution with respect to Common Stock (except any distribution specifically provided for in Sections 7(a) and 7(b)),
including in connection with any direct or indirect sale, license, assignment or other disposition of any of the material assets
(whether in one or a series of related transactions and regardless of the form of transaction) associated with the “Manocept”
or “Macrophage Therapeutics” subsidiaries or divisions of the Company, or any sale or other disposition of the securities
of any such subsidiary, then, in each such case, provision shall be made by the Company such that Holder shall receive upon exercise
of this Warrant a proportionate share of any such dividend or distribution as though it were Holder of the Warrant Shares as of
the record date fixed for the determination of the shareholders of the Company entitled to receive such dividend or distribution.


 


(d)          Adjustment
of Number of Shares. Upon each adjustment in the Warrant Price, the number of Warrant Shares purchasable hereunder shall be
adjusted, to the nearest whole share, to the product obtained by multiplying the number of Warrant Shares purchasable immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of which shall be the Warrant Price immediately prior
to such adjustment and the denominator of which shall be the Warrant Price immediately thereafter.


 


Section 8.          Notice
of Adjustments; Redemption. Whenever any Warrant Price or the kind or number of securities issuable under this Warrant shall
be adjusted pursuant to Section 7 hereof, the Company shall prepare a certificate signed by an officer of the Company setting forth,
in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was
calculated, and the Warrant Price and number or kind of shares issuable upon exercise of this Warrant after giving effect to such
adjustment, and within thirty (30) days of such adjustment shall cause copies of such certificates to be delivered to Holder in
accordance with Section 17 hereof.
