SEPARATION AGREEMENT AND RELEASE

 

THIS SEPARATION
AGREEMENT AND RELEASE (the “Agreement”) which becomes effective following the expiration of the revocation
period set forth below in this Agreement, is entered into between Navidea Biopharmaceuticals, Inc., on behalf of itself and its
partners, officers, employees and agents, the shareholders, directors, officers, employees and agents of its partners, and affiliated,
predecessor, successor, and other related companies, and each of them, jointly and severally (herein singularly and collectively
called “Navidea”), and Mark J. Pykett, V.M.D., Ph.D., on behalf of himself and his heirs, executors, guardians,
administrators, successors, and assigns, and each of them, jointly and severally (herein singularly and collectively called “Executive”),
who together are sometimes referred to herein as the “Parties” and who agree to be bound by all of the terms
and conditions of this Agreement.

 

WHEREAS, the Parties
desire to fully, equitably, and completely settle and dispose of any and all claims of whatever kind or nature which Executive
ever had, may now have, or may hereafter have, whether known or unknown, against Navidea, including but not limited to, those claims
related to Executive’s employment with and termination of employment from Navidea.

 

NOW, THEREFORE, in
consideration of the mutual agreements of the Parties set forth below, including the payments to Executive by Navidea provided
below, the receipt and legal sufficiency of which is hereby acknowledged, accepted and agreed to, the Parties hereby agree as follows:

 

1.            Termination.
The Parties confirm that Executive’s employment, including his service in all offices, positions, titles and capacities he
may hold with Navidea and any of its affiliates, is terminated effective as of 5:00 p.m., Columbus, Ohio time on May 30, 2014 (the
“Termination Date”). Notwithstanding the foregoing, Executive shall: (a) remain a member of Navidea’s
Board of Directors for the balance of his current term expiring at Navidea’s annual meeting of stockholders in July, 2014,
or until his earlier resignation or removal as a director in conformity with the Bylaws of Navidea, and shall receive fees and
expense reimbursements for such service as are established from time to time by the Board of Directors and (b) shall serve Navidea
in the capacity of a consultant pursuant to the terms of the Consulting Agreement attached hereto as Exhibit A (the “Consulting
Agreement”). Executive understands and agrees that he will not be nominated for election as a director for any term commencing
on or after Navidea’s 2014 annual meeting of stockholders. It is understood and agreed by the Parties that the termination
of Executive's employment qualifies as a “Termination Without Cause” under Section 4.D. of the Executive's Employment
Agreement dated April 15, 2014 (the “Employment Agreement”). However, notwithstanding the terms of the Employment
Agreement, Executive is not entitled to any payment, benefit, or benefit accrual, or to participation in any Navidea benefit plan
or program, at any time on or after the Termination Date, except as set forth in this Agreement; and further provided that Executive
shall remain fully covered and insured under Navidea’s Directors and Officers liability insurance policy and will continue
to be named as a participant thereunder during his term as a Director. Thereafter, Navidea will use its best commercial efforts
to maintain insurance and coverage of Executive as a former officer and director under Navidea’s Directors and Officers liability
policies, to the fullest extent permitted under Navidea’s certificate of incorporation, bylaws and applicable Delaware law;
provided that the scope and amount of coverage of Executive shall not be less than that maintained by the Company for other former
officers or directors.

(a)            Options.
Executive and Navidea confirm that: (i) Executive currently holds unexercised options to purchase Navidea common shares aggregating
962,000 common shares (the “Options”) under Navidea’s Fourth Amended and Restated 2002 Stock Incentive
Plan (the “Plan”), and (ii) notwithstanding anything to the contrary in the Plan, Executive shall remain entitled
to continue to vest in and to exercise the Options in accordance with, and subject to the restrictions and limitations contained
in, the Plan, and the termination of the Consulting Agreement will be treated as Executive’s “Termination of Service”
for purposes of the Plan. To the extent that the terms of any grant agreement or equity compensation plan under which Executive’s
unexercised options were awarded may be inconsistent with the preceding sentence, such agreement is hereby amended to conform therewith.

 

    	2

    	 

    

 

(b)            Restricted
Stock. Executive and Navidea further confirm that (i) Executive has certain unvested restricted shares of Navidea under two
restricted stock award agreements dated November 15, 2010 (175,000 unvested shares), and February 17, 2012 (as amended March 17,
2014 (100,000 unvested shares) (collectively, and as amended herein, the “Award Agreements”). Notwithstanding
any contrary terms in the Award Agreements or the Plan, (x) the 175,000 unvested shares under the November 15, 2010 Award Agreement
shall immediately and automatically be forfeited and assigned back to Navidea on the Termination Date, and (y) the vesting schedule
contained in the Award Agreement dated February 17, 2012 is hereby amended to read as follows:

 

“One-third
(1/3) of the shares vest on each of the first three (3) anniversaries of the grant date, as follows: 100,000 shares vest on February
17, 2013; 100,000 shares vest on March 17, 2014; and 100,000 shares vest on December 1, 2014. 100% of the shares vest in the event
of a Change of Control of the Company as defined in the Plan.”

 

Further, the termination
of Executive’s employment pursuant to Section 1 of this Agreement shall not be considered as a termination of his employment
with Navidea for purposes of Section 3.2 of the Award Agreement dated February 17, 2012, but the termination of the Consulting
Agreement shall constitute the termination of Executive’s employment thereunder.

 

(c)            Securities
Trading Policies. Notwithstanding anything to the contrary in this Agreement, Executive's right to exercise options to purchase,
or trade in, Navidea common stock remains subject, for so long as Executive shall remain a director of Navidea, to Navidea’s
Securities Trading Policy for Officers, Directors and Key Employees, as the same may be amended from time to time; provided, however,
Executive may exercise options to purchase Navidea common stock for cash at any time after the Termination Date. Executive acknowledges
his continuing obligation to comply with applicable law with respect to trading in the securities of Navidea and its affiliates.

 

2.4.            Healthcare
Coverage. Executive and his spouse and children will continue to participate in family coverage (including vision and dental
coverage) offered under Navidea’s group health plan, on the same terms and conditions that are applicable to other executive
employees of Navidea during the term of the Consulting Agreement, and for a period of eighteen (18) months thereafter will provide
continuation of benefits under COBRA in comformity with the terms of the group health plan. Notwithstanding the foregoing, if Navidea
reasonably determines that such a continuation of health coverage may not be exempt from federal income tax, Executive shall pay
to Navidea an amount equal to the stated taxable cost of such coverage, and following the expiration of the such eighteen (18)
month period, Executive shall receive from Navidea a reimbursement of the amounts paid by Executive. Further notwithstanding the
foregoing, in the event that such a continuation of coverage cannot be made available after the end of the period during which
continuation coverage is generally available under Navidea’s group health plan, Navidea shall assist Executive in finding
other comparable coverage and shall reimburse Executive for the costs of such coverage so as to make the net benefit to Executive
of such other continued coverage consistent, to the extent reasonably possible, with the coverage that was available under Navidea’s
group health plan during the period such coverage was permitted to be continued, with such reimbursement to be provided in a manner
consistent with the requirements of Treasury Regulation Section 1.409A-3(i)(iv). Any such reimbursements shall be subject to the
following conditions: (i) the benefits or payments provided during any taxable year of Executive may not affect the benefits or
payments to be provided to Executive in any other taxable year; (ii) reimbursement of any eligible expense must be made on or before
the last day of the Executive’s taxable year following the taxable year in which the expense was incurred; and (iii) the
right to such benefits or payments is not subject to liquidation or exchange for another benefit or payment.

2.5.            Other Benefit
Plans. During the term of the Consulting Agreement, Executive shall continue to participate in Navidea’s group term life
and disability benefit plans, but his ability to contribute to Navidea’s flexible spending plan and 401(k) plan (including
the employer match provisions) will terminate on the Termination Date, provided that the foregoing shall not limit Executive’s
right to make withdrawals or transfers from such plans in accordance with their terms.

party if the arbitrator determines that a party has made a frivolous claim or defense, where the arbitrator decides that such an
award is just. In any arbitration instituted under this Agreement, the arbitrator shall have the authority to render a decision

Statement of Agreement

 

In consideration of
the foregoing premises and the mutual covenants contained herein, and for other good and valuable consideration, the receipt and
legal adequacy of which is hereby acknowledged, accepted and agreed to, the Parties hereby agree as follows:

 

		1.	Engagement.

 

		(a)	This Agreement shall take effect on June 1, 2014 (the “Effective Date”) provided that
the Separation Agreement is in effect on the Effective Date. For a term beginning on the Effective Date and ending December 31,
2014, or the earlier termination of this Agreement pursuant to Section 5, Company hereby engages Consultant and Consultant hereby
accepts engagement from Company to provide such services as may be reasonably requested by the Chief Executive Officer of Company,
and other officers of the Company authorized by its Board of Directors (“Authorized Officers”), including advice
and assistance to the Company with respect to scope of services described in Section 1(b) below. Consultant shall use good faith
efforts to respond to requests for his services under this Agreement in a timely, responsive and efficient manner, and shall devote
substantially all of Consultant’s business time thereto. Consultant agrees not to become engaged in any other business activity
which, in the reasonable judgment of the Board of Directors of the Company (“Board”), is likely to materially interfere
with Consultant’s ability to discharge his duties and responsibilities to the Company hereunder. Nothing herein shall preclude
Consultant from: (i) serving on the boards of directors of other for-profit companies that do not compete with the Company, (ii)
serving on civic or charitable boards or committees and (iii) managing personal investments, so long as all such activities described
in (i) through (iii) above do not materially interfere with the performance of Consultant’s duties and responsibilities under
this Agreement. Consultant acknowledges and agrees that he is not an agent of the Company or any of its affiliates, and except
as may be expressly authorized or directed by an Authorized Officer, Consultant is not authorized to, and shall not, have any contact
with the Company's or its affiliates’ employees, suppliers, vendors or other persons with respect to the business or other
affairs of the Company or its affiliates, and Consultant is not authorized to take any actions binding upon or in the name of the
Company or any of its subsidiaries or affiliates.

 

    	 

    	 

    

 

		(b)	The scope of Consultant’s services are: (i) oversight of clinical-regulatory activities and,
in consultative role with the Authorized Officers, (ii) assistance with commercial activities, including Lymphoseek®
life-cycle management activities and investigator-initiated clinical studies, (iii) assistance with overall program management
and personnel management, (iv) responsibility for management of the Manocept platform as director of Manocept technology development,
including business development opportunities for the technology, which may include rheumatoid arthritis and cardiovascular indications,
and (iv) assistance to the Authorized Officers with business development, including partnering activities for Lymphoseek in Europe
and China, and potential partnering for the Company’s neurotracers.

 

		2.	Compensation of Consultant. As compensation for the services to be performed by Consultant
and in exchange for his obligations under the noncompete, nonsolicitation and confidentiality provisions of this Agreement:

 

		(a)	the Company shall pay to Consultant a consulting fee at the rate of $27,500.00 per month, which
will be paid semi-monthly during the term of this Agreement by direct deposit to the Consultant’s account. In addition to
cash compensation, the Company agrees to reimburse Consultant with fifteen (15) days, for reasonable out-of-pocket expenses incurred
by Consultant in connection with the services performed under this agreement, provided, however, that Consultant shall not incur
any expense in excess of $1,000 in any monthly period without prior written authorization of an Authorized Officer. Consultant’s
travel shall be consistent with the travel policies of the Company. These expenses include but are not limited to airfare, hotel
lodging, meals, transportation, and overnight express mail. Consultant shall render a monthly itemized statement detailing the
expense reimbursements due hereunder, accompanied by copies of receipts for all expenses consistent with Company policies.

 

		(b)	the Company shall grant to Consultant under the Company’s Fourth Amended and Restated 2002
Stock Incentive Plan (“Plan”) a restricted stock award of 40,000 shares of the Company’s common stock,
$.001 par value, to vest as follows:

 

		(i)	as to 20,000 shares, on December 31, 2014, provided this
Agreement has not terminated prior to such date;

 

    	2

    	 

    

 

		(ii)	as to 10,000 shares, on December 1, 2014, provided that
a business transaction involving the Company’s Manocept platform (other than with respect to Lymphoseek) has been consummated
on or before such date and before the expiration or termination of this Agreement;

		(iii)	as to 5,000 shares, on December 1, 2014, provided that
a Lymphoseek sNDA has been approved by U.S. FDA on or before such date and before the expiration or termination of this Agreement;
and

		(iv)	as to 5,000 shares, on December 1, 2014, provided the
Lymphoseek MAA has been approved by the European Medicines Agency on or before such date and before the expiration or termination
of this Agreement.

 

Notwithstanding the provisions
of clauses (ii) through (iii) above, if this Agreement has been terminated by the Company for reason other than a breach by Consultant,
or if this Agreement terminates on December 31, 2014 as a result of the expiration of its term, and Consultant has provided services
hereunder contributing to the achievement of a milestone specified in any of such clauses (ii) through (iii), the vesting date
specified such clause shall be extended for a period of six (6) months following the date of termination or expiration of this
Agreement. These restricted stock awards shall be subject to the terms of the Plan and any separate award agreement(s) with respect
to such awards.

 

		3.	Confidentiality.

 

		(a)	The Company is prepared to make available to Consultant certain information concerning the business,
financial condition, operations, assets and liabilities, or other internal and confidential business information of the Company
in connection with the performance of his duties hereunder. As a condition to such information being furnished to Consultant, Consultant
agrees to treat any information concerning the Company (whether prepared by the Company, its officers, advisors, Board, or otherwise
and irrespective of the form of communication) which is furnished to Consultant now or in the future by or on behalf of the Company
(herein collectively referred to as the “Confidential Information”) in accordance with the provisions of this
Agreement, and to take or abstain from taking certain other actions hereinafter set forth. The term “Confidential Information”
also shall be deemed to include all notes, analyses, compilations, studies, interpretations or other documents prepared by Consultant,
which contain, reflect or are based upon, in whole or in part, the information furnished to Consultant, pursuant hereto. The term
“Confidential Information” does not include information which: (i) is or becomes generally available to the
public other than as a result of a disclosure by Consultant, or (ii) becomes available to Consultant on a non-confidential basis
from a source other than the Company (including the Company’s directors, officers, employees or agents), or any of its attorneys,
accountants, investors, consultants, bankers and financial advisors, provided that such source is not bound by a confidentiality
agreement with or other contractual, legal or fiduciary obligation of confidentiality to the Company or any other party with respect
to such information.

 

    	3

    	 

    

 

		(b)	Consultant hereby agrees that Consultant shall use the Confidential Information solely for the
purpose of rendering the services contemplated by this Agreement, that the Confidential Information will be kept confidential and
that Consultant and will not disclose any of the Confidential Information in any manner whatsoever; provided, however, that Consultant
may make any disclosure of such information to which the Company gives its prior written consent. Consultant acknowledges that
the Confidential Information may contain material nonpublic information about the Company, and that he is aware that the U.S. securities
laws prohibit a person in possession of material nonpublic information of a company from purchasing or selling securities of that
company, or from communicating such information to any other person under circumstances in which it is reasonably foreseeable that
such person is likely to purchase or sell such securities.

 

		4.	Noncompetition and Nonsolicitation.

 

		(a)	Consultant agrees that during the term of this Agreement and for a period of one (1) year thereafter,
Consultant will not: (i) enter into the employ of or render any services or advice to any person, firm, or corporation, which is
engaged, in any part, in a Competitive Business (as defined below) anywhere in the world; (ii) engage in any Competitive Business
for his own account; (iii) become associated with or interested in, through contract, retention, by employment or otherwise, any
Competitive Business as an individual, partner, shareholder, creditor, director, officer, principal, agent, employee, trustee,
consultant, advisor, or in any other relationship or capacity; (iv) solicit, interfere with, or endeavor to entice away from the
Company, any of its customers, strategic partners, investors, or sources of supply; or (v) hire any person who is an employee of
the Company or any subsidiary or affiliate, or otherwise induce or attempt to induce any employee of the Company or any subsidiary
or affiliate to leave the employ of the Company or such entity, or in any way interfere with the relationship between the Company
or any subsidiary or affiliate and any employee thereof.

 

		(b)	Nothing in this Agreement shall preclude Consultant from investing his personal assets in the securities
of any Competitive Business if such securities are traded on a national stock exchange or in the over-the-counter market and if
such investment does not result in his beneficially owning, at any time, more than one percent (1%) of the publicly-traded equity
securities of such Competitive Business. “Competitive Business” for purposes of this Agreement shall mean any
business or enterprise which:

 

		i.	is engaged anywhere in the world in (A) the development and/or commercialization of products and/or
systems for use in the pre-operative or intraoperative detection of cancer, (B) the development and/or commercialization of radiopharmaceuticals

		(c)	Consultant acknowledges that the limitations contained in this Section 4 are an essential term
and consideration for the execution of this Agreement by the Company and that the time and geographic limitations are reasonable
and necessary to protect the Company and its business interests. The Company shall be entitled to injunctive relief, damages, reasonable
attorneys' fees and expenses in connection with any legal or equitable action by the Company in connection with a breach or threatened
breach by Consultant of Sections 3 or 4 of this Agreement.

 

		5.	Termination. The obligation of Consultant to provide
services under this Agreement, and the Company's obligation to provide compensation to Consultant under this Agreement, shall
terminate upon the first to occur of the following: (a) December
31, 2014; or (b) the death or permanent disability of Consultant. In addition, this Agreement may be terminated by Consultant
at any time by giving thirty (30) days prior written notice of termination. This Agreement may be immediately terminated by the
Company if the Consultant: (w) is formally charged with a felony (other than a traffic offense), or any crime involving moral
turpitude, that in the reasonable good faith judgment of the Board would result in material damage to the Company or its reputation,
or would materially interfere with the performance of Consultant’s obligations under this Agreement; (x) engages in acts
of fraud, embezzlement, theft or other material dishonesty directed against the Company; (y) materially breaches any duty or obligation
of Consultant under this Agreement that is not cured to the Company’s reasonable satisfaction within fifteen (15) business

		7.	Assignment; Binding Effect. This Agreement, being
personal to Consultant, may not be assigned by Consultant. This Agreement may be assigned by the Company to any entity that acquires
substantially all of the assets and business of the Company, whether by merger, acquisition of equity securities, or acquisition
of assets so long as the assignee agrees, in writing, to be bound by the terms of this Agreement. This Agreement shall be binding
upon the Parties and their respective legal successors and permitted assigns.

 

		8.	Independent Contractor. Consultant shall have no
authority to bind Company, or any of its subsidiaries or affiliates, to any agreement or obligation. The Parties will be deemed

irrevocably consents to the jurisdiction of the foregoing named courts in any such suit, action or procedure. Each of the Company
and Consultant further agrees to accept and acknowledge service of any and all process which may be served in any suit, action
or proceeding in the foregoing courts, and agrees that service of process upon the Company or Consultant mailed by certified mail
to the address of the recipient otherwise appearing in this Agreement shall be deemed in every respect effective service of process
upon the Company in any such suit, action or proceeding.

 

    	6

    	 

    

 

		10.	Equitable Relief. Consultant agrees that money
damages would not be a sufficient remedy for any breach or threatened breach by Consultant of Sections 3 and 4 of this Agreement
and that the Company shall be entitled to specific performance and injunctive or other equitable relief as a remedy for any such
breach, and Consultant further agrees to waive any requirement for the securing or posting of any bond in connection with such
remedy. Such remedy shall not be deemed to be the exclusive remedy for breach of this Agreement, but shall be in addition to all
other remedies available to the Company at law or equity.

 

		11.	Construction. The captions contained in this Agreement
are for convenience of reference only and are not to be considered in construing this Agreement. The language of this Agreement
shall be construed as to its fair meaning and not strictly for or against any party.

 

		12.	Entire Agreement. This Agreement constitutes the
entire agreement between the Parties with respect to its subject matter and there are no representations, warranties or agreements
between the Parties, which are not expressed herein. This Agreement supersedes and replaces all prior understandings and agreements
between the Parties hereto, whether written or oral, expressed or implied, with respect to its subject matter, it being understood
and agreed, however, that this Agreement does not supersede or replace the Separation Agreement, which shall remain in full force
and effect pursuant to its terms.

 

		13.	Amendment. This Agreement may not be amended, modified,
superseded, canceled or terminated, and any of the matters, covenants, representations, warranties or conditions hereof may not
be waived, except by written instrument executed by the Parties hereto or, in the case of a waiver, by the party to be charged
with such a waiver.

 

		14.	Severability. The provisions of this Agreement
are independent of and severable from each other, and no provision shall be affected or rendered invalid or unenforceable by virtue
of the fact that for any reason any other or others of them may be invalid or unenforceable in whole or in part. Further, if a
court of competent jurisdiction determines that any provision of this Agreement is invalid or unenforceable as written, such court
may interpret, construe, rewrite or revise such provision, to the fullest extent allowed by law, so as to make it valid and enforceable
consistent with the intent of the Parties hereto.

 

		15.	Counterparts. This Agreement may be executed in
counterparts, each of which shall be deemed an original agreement, but all of which together shall constitute one and the same
instrument. Execution and delivery of this Agreement by facsimile transmission (including the delivery of documents in Adobe PDF
format) shall constitute execution and delivery of this Agreement for all purposes, with the same force and effect as execution
and delivery of an original manually signed copy hereof.
