Exclusivity. The Executive hereby represents to the Company that: (i) the execution and delivery of this Agreement
by the Executive and the Company and the performance by the Executive of the Executive’s duties hereunder do not and shall

hereunder; (iii) the Executive is not bound by any agreement with any previous employer or other party to refrain from (A) competing

Section
3. Compensation.


 


(a)            
Salary. In consideration of all of the services rendered by the Executive under the terms of this Agreement, the
Company shall pay to the Executive a base salary at the annualized rate of Three Hundred Thousand Dollars United States ($300,000.00)
per annum, less payroll deductions and all required withholdings. Executive’s Base Salary shall be subject to annual review
and upward adjustment only by the Board or a committee thereof, beginning in fiscal 2018. The Base Salary shall be paid in accordance
with the customary payroll practices of the Company in effect from time to time. The Executive’s salary, as adjusted from
time to time under this Section 3(a), is referred to as (“Base Salary”).


 


(b)            
Annual Bonus. With respect to each Company fiscal year that ends during the Term, commencing with fiscal year 2017,
the Executive shall be eligible to receive an annual performance-based cash bonus (the “Annual Bonus”) which shall
be payable based upon the attainment of individual and/or Company performance goals established by the Board or a committee thereof.
The target amount of such Annual Bonus shall equal 50% of Executive’s Base Salary in the year to which the Annual Bonus relates,
provided that the actual amount of the Annual Bonus may be greater or less than such target amount (the “Target Bonus”).
Each Annual Bonus, if any, for a fiscal year shall be payable, less payroll deductions and all required withholdings, not later
than the fifteenth day of the third month following the end of such year. Except as provided in Section 7, notwithstanding any
other provision of this Section 3(b), no bonus shall be payable with respect to a Company fiscal year unless the Executive remains
continuously employed with the Company until the last day of such year.


 


(c)            
Reimbursement of Expenses. The Company will promptly reimburse Executive for all reasonable out-of-pocket business
expenses that are incurred by Executive in furtherance of the Company’s business in accordance with the Company’s policies
with respect thereto as in effect from time to time. Without limiting the foregoing, the Company shall reimburse the Executive
for the Executive’s reasonable travel and lodging expenses in connection with the Executive’s travel for business purposes

and its subsidiaries and the Company shall withhold from such payment all amounts required to be deducted or withheld under applicable
law. The Executive shall be reimbursed by the Company for the reasonable attorneys’ fees and costs incurred by him in connection
with the negotiation and preparation of this Agreement (and related equity award documentation), up to a maximum of $5,000 provided
that the Executive shall submit invoices to the Company within ninety (90) days of incurrence of the expense, and the Company shall
reimburse Executive within sixty (60) days thereafter.


 


(d)            
Fringe Benefits. In addition to any benefits provided by this Agreement, Executive shall be entitled to participate
generally in all employee benefit, welfare and other plans, practices, policies and programs and fringe benefits maintained by
the Company from time to time on a basis no less favorable than those provided to other similarly-situated executives of the Company.
The Executive understands that, except when prohibited by applicable law, the Company’s benefit plans and fringe benefits
may be amended, enlarged, diminished or terminated prospectively by the Company from time to time, in its sole discretion, and
that such shall not be deemed to be a breach of this Agreement. Regardless of where the Executive is based, the Company shall procure
and pay for a comprehensive health check for the Executive once per year during the Term, until the termination of the Executive’s
employment, to be carried out by a medical professional agreeable to the Executive (acting reasonably).


 


(e)            
Vacation. Executive shall be entitled to accrue four (4) weeks of paid vacation days per year in accordance with

employment with the Company, the Company shall maintain the insurance it currently has with respect to (i) directors’ and
officers’ liability, (ii) errors and omissions and (iii) general liability insurance providing coverage to Executive to the
same extent as other senior executives and directors of the Company. Executive’s coverage under such insurance shall terminate

“RSUs”) under the Company’s Amended and Restated Xenetic Biosciences, Inc. Equity Incentive Plan, adopted by
the Board of Directors on October 11, 2017, as amended from time to time (the “Plan”) for 50,000 shares of the Company’s
common stock. The RSUs shall vest one-third upon the first anniversary of the Effective Date, one-third upon the second anniversary
of the Effective Date and one-third upon the third anniversary of the Effective Date, provided the Executive remains employed with

Plan, while Executive is employed by the Company, any unvested portion of the RSUs shall vest immediately upon the Change in Control,
or (ii) a termination of this Agreement by the Company under Section 7(b) or the Executive under Section 7(c), any unvested portion
of the RSUs shall vest immediately upon such termination. The RSUs (including the distribution of any shares of the Company’s
common stock issuable pursuant thereto) shall be subject to the terms of the Plan, and a Restricted Stock Unit Agreement in a form
acceptable to the Committee, which shall include the terms provided herein. The Company represents and warrants to the Executive
that (i) this Agreement and the RSUs have been duly authorized by the Company’s Compensation Committee of the Company’s
Board of Directors (the “Compensation Committee”) and are the valid and binding obligations of the Company, enforceable
in accordance with their respective terms; and (ii) the grant of the RSUs does not violate applicable law or Nasdaq listing requirements.


 


(b)            
Delivery of Shares. The Restricted Stock Unit Agreement described in Section 5(a) shall require the Company to deliver shares
of Company’s Common Stock (as defined in the Plan) in satisfaction of the vested RSUs granted under such Agreement to the
Participant or direct its transfer agent to register such shares in book entry form, upon, but in no event later than thirty (30)

the “Delivery Event”); provided, however, that the delivery of shares shall be delayed until the earlier of (A) six
months following separation from service, or (B) the Participant’s death, if necessary to comply with the requirements of
Code Section 409A. All shares underlying vested Restricted Stock Units shall be delivered to Participant upon a Delivery Event
regardless as to the reason triggering such Delivery Event (including the reason the Participant’s service is terminated).


 


(c)            
Stock Option Grant. The Company shall grant to Executive on the Effective Date a stock option to purchase 250,000 shares
of common stock of the Company (the “Option”) under the Plan at an exercise price equal to the fair market value of
the Company’s common stock on the grant date. Fifty percent of the Option shall vest one-third upon the first anniversary
of the Effective Date, one-third upon the second anniversary of the Effective Date and one-third upon the third anniversary of
the Effective Date, a portion of the Option to purchase 100,000 shares of common stock of the Company shall vest upon the achievement
of key clinical milestones for XBIO-101 as further described in the Option award agreements, and a portion of the Option to purchase
25,000 shares of common stock of the Company shall vest upon the achievement of key development milestones related to PSA as further
described in the Option award agreements, provided the Executive remains employed with the Company on the applicable vesting date
and further provided that, in the event of (i) a Change in Control, as defined in the Plan, while Executive is employed by the
Company, any unvested portion of the Option shall vest immediately upon the Change in Control, or (ii) a termination of this Agreement
by the Company under Section 7(b) or the Executive under Section 7(c), any unvested portion of the Option shall vest immediately
upon such termination. Notwithstanding the foregoing in no event may (i) Executive exercise the Option prior to the Company receiving
shareholder approval of an increase in the number of shares of common stock authorized under the Plan which amendment to the Plan
shall include provision for the issuance of shares of common stock underlying the Option; and (ii) if shareholder approval is not
obtained for any reason on or prior to October 11, 2018, the Option shall be cancelled and of no further force and effect. A cancellation
of the Option shall in no event be deemed a breach of this Agreement. The Option shall be evidenced in writing by, and subject
to the terms and conditions of, the Plan or such new plan covering the Option with terms that are the same as or materially similar
to the terms of the Plan and, except as otherwise set forth herein, the Company’s standard form of stock option agreement,
which agreement shall expire ten (10) years from the date of grant except as otherwise provided herein, in the stock option agreement
or the Plan. The Executive shall be eligible to receive from time to time additional equity awards under the Plan. The Company
represents and warrants to the Executive that (i) this Agreement and the Option have been duly authorized by the Company’s
Board of Directors or a committee thereof and are the valid and binding obligations of the Company, enforceable in accordance with
their respective terms, including the Company’s right to terminate the Option if no stockholder consent is obtained in a
timely manner; and (ii) the grant of the Option does not violate applicable law or Nasdaq listing requirements.

Section

During the Term, the
Executive shall observe all Company rules, regulations, policies, procedures and practices in effect from time to time, including,
without limitation, such policies and procedures as are contained in the Company policy and procedures manual, as may be amended
or superseded from time to time.


 


Section
7. Termination of Employment.


 


Executive’s
employment with the Company may be terminated during Term of this Agreement for any of the following reasons:


 


(a)            
By The Company For Cause. At any time during the Term, the Company may terminate Executive’s employment hereunder
for Cause. For purposes of this Agreement, “Cause” shall mean the occurrence of any of the following events: (i) conduct
by Executive constituting a material act of willful misconduct in connection with the performance of his duties, including, without
limitation, misappropriation of funds or property of the Company or any of its affiliates other than the occasional, customary
and de minimis use of Company property for personal purposes; (ii) the commission by Executive of a felony or any misdemeanor
involving moral turpitude, deceit, dishonesty or fraud, or conduct by Executive that would reasonably be expected to result in
material injury to the Company if he were retained in his position; (iii) continued, willful and deliberate non-performance by
Executive of his duties hereunder (other than by reason of Executive’s physical or mental illness, incapacity or disability)
which has continued for more than thirty (30) days following written notice of such non-performance from the Company; (iv) a material
breach by Executive of any of the provisions contained in Section 9 of this Agreement; (v) a material violation by Executive of
the Company’s employment policies which has continued for more than thirty (30) days following written notice of such violation
from the Company; or (vi) willful failure to cooperate with a bona fide internal investigation or an investigation by regulatory
or law enforcement authorities, after being instructed by the Company to cooperate, or the willful destruction or failure to preserve
documents or other materials known to be relevant to such investigation or the willful inducement of others to fail to cooperate
or to produce documents or other materials. In the case of any termination for Cause, the Company shall provide written notice
to the Executive setting forth the acts, circumstances and bases that constitute Cause for termination.


 


(b)            
By The Company Without Cause.


 


At any time during
the Term, the Company may terminate Executive’s employment hereunder without Cause. For purposes of this Agreement, non-renewal
of the Term by the Company other than due to Cause shall be treated as a termination of the Executive’s employment without
Cause.


 


(c)            
By The Executive.


 


At any time during
the Term, Executive may terminate his employment hereunder for any reason, including but not limited to Good Reason. For purposes
of this Agreement, “Good Reason” shall mean that Executive has complied with the “Good Reason Process”
(hereinafter defined) following the occurrence of any of the following events: (i) a substantial diminution or other substantive
adverse change, not consented to by Executive, in the nature or scope of Executive’s responsibilities, authorities, powers,
functions or duties; (ii) a breach by the Company of any of its other material obligations under this Agreement, including but
not limited to failure of the Company to make any material payment or provide any material benefit under this Agreement, (iii)
the cancellation of the Option due to the failure of the Company to receive shareholder approval of an increase in the number of
shares of common stock authorized under the Plan which amendment to the Plan shall include provision for the issuance of shares
of common stock underlying the Option, on or prior to October 11, 2018; or (iv) a change in the geographic location at which Executive
must perform his services as provided under this Agreement to a location more than thirty miles from the locations selected by
the Executive for providing his services from time to time as provided under Section 1(c). A change in the employment of Executive
to another affiliate of Company does not in and of itself constitute “Good Reason” (i.e., absent any of the acts, circumstances
or bases set forth in (i) through (iv) of this Section 7(c)). “Good Reason Process” shall mean that (A) Executive reasonably
determines in good faith that a “Good Reason” event has occurred; (B) Executive notifies the Company in writing of
the occurrence of the Good Reason event within ninety (90) days of the occurrence of such event; (C) Executive cooperates in good
faith with the Company’s efforts, for a period not less than sixty (60) days following such notice, to modify Executive’s
employment situation in a manner acceptable to Executive and Company; (D) notwithstanding such efforts, one or more of the Good
Reason events continues to exist and has not been modified in a manner acceptable to Executive; and (E) Executive terminates his
employment no later than sixty (60) days after the end of the sixty (60) day cure period. If the Company cures the Good Reason
event in a manner acceptable to Executive during the sixty (60) day period, Good Reason shall be deemed not to have occurred.

(d)            
Right to Severance.


 


In the event the Company
terminates Executive’s employment Without Cause or the Executive terminates employment for Good Reason as provided in Section
7(c) and if Executive executes and does not revoke during any applicable revocation period a general release of all claims against
the Company and its affiliates in a form acceptable to the Company (a “Release of Claims”) within a reasonable
period of time specified by the Company and in compliance with applicable law, following such termination, then in addition to
any accrued obligations payable under Section 7(e)(i) below, the Company shall:


 


(i)             
Pay to the Executive, within thirty (30) days following the date of termination, an amount equal to one times Executive’s
Base Salary (determined after disregarding any reduction in Base Salary that constitutes Good Reason), less payroll deductions
and all required withholdings;


 


(ii)           
Pay to the Executive an amount equal to the product of (A) the amount of the Annual Bonus that would have been payable to
the Executive pursuant to Section 3(b) if the Executive was still employed as of December 31st of the then current fiscal year
in respect of the fiscal year in which employment termination occurs based on the Company’s achievement against the performance
goals applicable to such year (after deeming any individual goals to be met at the target level), and (B) the ratio of (x) the
number of days elapsed during the fiscal year during which such termination of employment occurs on or prior to the date of such
termination to (y) 365, payable as of the same time as annual bonuses are paid to other senior executives; and


 


(iii)         
Notify Executive of any right to continue group health plan coverage sponsored by the Company immediately prior to Executive’s
date of termination pursuant to the provisions of applicable law including, but not limited to, the provisions of the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”). If Executive elects to receive such continued
healthcare coverage, the Company shall directly pay, or reimburse Executive for, the premium for Executive and Executive’s
covered dependents, less the amount of Executive’s monthly premium contributions for such coverage prior to termination,
for the period commencing on the first day of the first full calendar month following such employment termination through the earlier
of (i) the last day of the month during the first twelve months following the date of termination, following the date the Release
of Claims becomes effective and irrevocable and (ii) the date Executive and Executive’s covered dependents, if any, become
eligible for healthcare coverage under another employer’s plan(s). Executive shall notify the Company immediately if Executive
becomes covered by a group health plan of a subsequent employer. After the Company ceases to pay premiums pursuant to this subsection,
Executive may, if eligible, elect to continue healthcare coverage at Executive’s expense in accordance the provisions of
COBRA or other applicable law.


 


For purposes of this Section 7(d), Executive’s
termination of employment at the end of the Term following an earlier notice of nonrenewal by the Company shall be treated as a
termination of the Executive’s employment by the Company without Cause as of the last day of the Term.


 


(e)            
Upon a termination of the Executive’s employment for any reason, (i) the Executive shall be entitled to receive: (A)
any portion of the Executive’s Base Salary through the date of employment termination not theretofore paid, (B) the Annual
Bonus owed to the Executive under Section 3(b) if it remains unpaid as of the date of such termination, (C) any expenses owed to
the Executive under Section 3(c) above, (D) any accrued but unused vacation pay owed to the Executive pursuant to Section 3(e)
above, and (E) any amount arising from the Executive’s participation in, or benefits under, any employee benefit plans, programs
or arrangements under Section 3(e), which amounts shall be payable in accordance with the terms and conditions of such employee
benefit plans, programs or arrangements.


 


(f)             
The payments and benefits described in this Section 7 shall be the only payments and benefits payable in the event of the
Executive’s termination of employment for any reason.


 


Section
8. Survival of Obligations.


 


The obligations of
the Executive as set forth in Section 4, Section 7 and Sections 9 through 17 below shall survive the term of this Agreement and
the termination of Executive’s employment hereunder regardless of the reason(s) therefor.

During the Term, the Executive shall not, directly or indirectly, either as an Executive, employer, employee, consultant,
agent, principal, partner, officer, director, shareholder, member, investor or in any other individual or representative capacity,
engage or participate in any business or business related activity of any kind that is in competition in any manner whatever with
the business of the Company or any business activity related to the business in which the Company is now involved or becomes involved
during the Executive’s employment. For these purposes, the current business of the Company is described in the Company’s
Annual Report on Form 10-K for the year ended December 31, 2016. The Executive also agrees that, during his employment with the
Company, he will not engage in any other activities that materially conflict with his obligations to the Company, it being understood
that activities approved by the Board under Section 2(b) or otherwise in writing shall not be considered to violate this Section
9(a).


 


(b)            
As a material inducement to the Company to continue the employment of the Executive, and in order to protect the Company’s
Confidential Information and good will, the Executive agrees that:


 


(i)             
For a period of twelve (12) months following termination of the Executive’s employment with the Company or its affiliates
for any reason, Executive will not directly or indirectly solicit or divert or accept business relating in any manner to Competing
Products or to products, processes or services of the Company, from any of the customers or accounts of the Company with which
the Executive had any contact as a result of Executive’s employment with the Company; and


 


(c)            
For a period of twelve (12) months after termination of Executive’s employment with the Company or its affiliates
for any reason, Executive will not (A) render services directly or indirectly, as an Executive, consultant or otherwise, to any
Competing Organization in connection with research on or the acquisition, development, production, distribution, marketing or providing
of any Competing Product, or (B) own any interest in any Competing Organization except as an investor or stockholder of more than
2% of the equity securities of any entity:


 


(i)             
“Competing Products” means any product, process, or service of any person or organization other than the Company,
in existence or under development (a) which is identical to, substantially the same as, or an adequate substitute for any product,
process or service of the Company in existence or under development, based on any patent or patent application (provisional or
otherwise), or other intellectual property of the Company about which the Executive acquires Confidential Information, and (b)
which is (or could reasonably be anticipated to be) marketed or distributed in such a manner and in such a geographic area as to
actually compete with such product, process or service of the Company; and


 


(ii)           
“Competing Organization” means any person or organization, including the Executive, engaged in, or about to
become engaged in, research on or the acquisition, development, production, distribution, marketing or providing of a Competing
Product.


 


(d)            
The parties agree that the Company is entitled to protection of its interests in these areas. The parties further agree
that the limitations as to time, geographical area, and scope of activity to be restrained do not impose a greater restraint upon
Executive than is necessary to protect the goodwill or other business interest of the Company. The parties further agree that in
the event of a violation of this Covenant Not To Compete, that the Company shall be entitled to the recovery of damages from Executive
and injunctive relief against Executive for the breach or violation or continued breach or violation of this Covenant. The Executive
agrees that if a court of competent jurisdiction determines that the length of time or any other restriction, or portion thereof,
set forth in this Section 9 is overly restrictive and unenforceable, the court may reduce or modify such restrictions to those
which it deems reasonable and enforceable under the circumstances, and as so reduced or modified, the parties hereto agree that
the restrictions of this Section 9 shall remain in full force and effect. The Executive further agrees that if a court of competent
jurisdiction determines that any provision of this Section 9 is invalid or against public policy, the remaining provisions of this
Section 9 and the remainder of this Agreement shall not be affected thereby, and shall remain in full force and effect.


 


Section
10. Confidentiality.


 


(a)

agree that the Company is entitled to protection of its interests in the Confidential Information. The Executive shall not at any
time, either during his employment and for seven (7) years after the termination of his employment with the Company for any reason,
or indefinitely to the extent the Confidential Information constitutes a trade secret under applicable law, disclose to others,

Section
18. Section 409A.


 


(a)            
It is intended that any compensation or benefits under this Agreement satisfy, to the greatest extent possible, the exemptions
from the application of Section 409A of the Internal Revenue Code of 1986, as amended (“Section 409A”) provided under
Treasury Regulations Sections 1.409A-1(b), and this Agreement will be construed to the greatest extent possible as consistent with
those provisions, and to the extent not so exempt, this Agreement (and any definitions hereunder) will be construed in a manner
that complies with Section 409A. For purposes of Section 409A, the Executive’s right to receive any installment payments
under this Agreement shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment
hereunder shall at all times be considered a separate and distinct payment. Severance benefits under Section 7(d) shall not commence
until the Executive has a “separation from service” for purposes of Section 409A.


 


(b)            
To the extent that any reimbursement of expenses or in-kind benefits constitutes deferred compensation under Section 409A,
such reimbursement or benefit shall be provided no later than December 31 of the year following the year in which the expense was
incurred. The amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent
year. The amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other
year.


 


(c)            
If the Executive is deemed at the time of his separation from service to be a specified employee for purposes of Section
409A(a)(2)(B)(i) of the Code, to the extent delayed commencement of any portion of the compensation and benefits to which the Executive
is entitled under this Agreement is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the
Code, such portion of the Executive’s termination benefits shall be provided to the Executive immediately after the earlier
of (A) the expiration of the six-month period measured from the date of the Executive’s separation from service with the
Company (as such term is defined in the Treasury Regulations issued under Section 409A of the Code) or (B) the date of the Executive’s
death in a lump sum, and any remaining payments due under the Agreement shall be paid as otherwise provided herein.

Section
19. Limitation of Payments upon Certain Events.


 


(a)            
Limitation on Payments. Notwithstanding anything in this Agreement to the contrary, if any payment or distribution
Executive would receive pursuant to this Agreement or otherwise (“Payment”) would (a) constitute a “parachute
payment” within the meaning of Section 280G of the Code), and (b) but for this sentence, be subject to the excise tax imposed
by Section 4999 of the Code (the “Excise Tax”), then the Company shall cause to be determined, before any amounts
of the Payment are paid to Executive, which of the following alternative forms of payment would maximize Executive’s after-tax
proceeds: (i) payment in full of the entire amount of the Payment (a “Full Payment”), or (ii) payment of only
a part of the Payment so that Executive receives that largest Payment possible without being subject to the Excise Tax (a “Reduced
Payment”), whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes
and the Excise Tax (all computed at the highest marginal rate, net of the maximum reduction in federal income taxes which could
be obtained from a deduction of such state and local taxes), results in Executive’s receipt, on an after-tax basis, of the
greater amount of the Payment, notwithstanding that all or some portion the Payment may be subject to the Excise Tax.


 


(b)            
The independent registered public accounting firm engaged by the Company for general audit purposes as of the day prior
to the date the first Payment is due shall make all determinations required to be made under this Section 19. If the independent
registered public accounting firm so engaged by the Company is serving as accountant or auditor for the individual, group or entity
effecting the transaction, the Company shall appoint a nationally recognized independent registered public accounting firm to make
the determinations required hereunder. The Company shall bear all expenses with respect to the determinations by such independent
registered public accounting firm required to be made hereunder.


 


(c)            
The independent registered public accounting firm engaged to make the determinations hereunder shall provide its calculations,
together with detailed supporting documentation, to the Company and Executive at such time as requested by the Company or Executive.
If the independent registered public accounting firm determines that no Excise Tax is payable with respect to a Payment, either
before or after the application of the Reduced Payment, it shall furnish the Company and Executive with an opinion reasonably acceptable
to Executive that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm
made hereunder shall be final, binding and conclusive upon the Company and Executive.


 


IN WITNESS WHEREOF,
the parties hereto have executed this Amended and Restated Employment Agreement under seal as of the date and year first above
written.
