EXPLANATORY NOTE



The Registrant is filing this Amendment
No. 1 on Form 10-K/A (this “Amendment”) to amend its Annual Report on Form 10-K for the fiscal year ended December 31,
2016 originally filed with the Securities and Exchange Commission (“SEC”) on March 31, 2017 (the “Original Filing”)
to include the information required by Items 10 through 14 of Part III of Form 10-K. This information was previously omitted from
the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above-referenced
items to be incorporated in the Form 10-K by reference from our definitive proxy statement if such statement is filed no later
than 120 days after our fiscal year-end. We are filing this Amendment to include Part III information in our Form 10-K because
our definitive proxy statement will be filed later this year. The reference on the cover of the Original Filing to the incorporation
by reference to portions of our definitive proxy statement into Part III of the Original Filing is deleted by this Amendment.



Part
III of the Original Filing (Items 10 through 14) is being amended and restated in its entirety by this Amendment. In addition,
the Exhibit Index that is incorporated by reference into Part IV, Item 15 of the Original Filing is being amended and restated
in its entirety by this Amendment. This Amendment does not amend or otherwise update any other information in the Original Filing.
Accordingly, this Amendment should be read in conjunction with the Original Filing. In addition,
this Amendment does not reflect events that may have occurred subsequent to the date of the Original Filing.



Pursuant to Rule 12b-15 under the Exchange
Act, this Amendment also contains new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which are attached
hereto. Because no financial statements are included in this Amendment and this Amendment does not contain or amend any disclosure
with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the certifications have been omitted.



As
used in this Amendment, unless otherwise indicated, all references herein to “Xenetic,” the “Company,”
“we” or “us” refer to Xenetic Biosciences, Inc. and its wholly owned subsidiaries.

Board Role in Risk Oversight



Our Board is responsible
for consideration and oversight of risks to us, and is responsible for ensuring that material risks are identified and managed
appropriately, including the evaluation of our risk assessment and risk management policies. In fulfilling this role, the Board
receives reports directly from management. In addition, the Board reviews areas of the Company’s material risk, including
operational, financial, legal, regulatory and strategic risks. The Board also considers specific risk topics in connection with
strategic planning and other matters.



Our Board of Directors



Currently, the
Board consists of seven (7) members: M. Scott Maguire, Jeffrey F. Eisenberg, Dr. Edward J. Benz, Firdaus Jal Dastoor, Darlene
Deptula-Hicks, Roman Knyazev, and Dr. Roger Kornberg. Mr. Maguire was appointed the Chairman of the Board in April 2017. Prior
to that, the Chairmanship was vacant. Directors shall hold office for a one-year term or until their successors have been duly
elected and qualified. Vacancies on the Board resulting from death, resignation, disqualification, removal, or other causes can
be filled by the affirmative vote of a majority of the directors then in office. Any director so elected, shall hold office for
the remainder of the full term of the director for which the vacancy was created or occurred and until such director’s successor
shall have been duly elected and qualified.



Committees of the Board



Our Board has designated
the following three standing committees: the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance
Committee. It has adopted charters to govern the conduct, authority and responsibilities of each of these committees.



Audit Committee



The Audit Committee
is responsible for making recommendations to the Board concerning the selection and engagement of independent accountants and
for reviewing the scope of the annual audit, audit fees, results of the audit and auditor independence. The Audit Committee also
reviews and discusses with management and the Board such matters as accounting policies, internal accounting controls and procedures
for preparation of financial statements. The Audit Committee held four (4) meetings during 2016. The Company’s Audit Committee
Charter provides that the Audit Committee shall consist of at least three members. Any vacancy occurring on the Audit Committee
may be filled only by the Nominating and Corporate Governance Committee. A copy of the current Audit Committee Charter is available
on the Company’s website, www.xeneticbio.com. Our website and the information contained therein are not incorporated into
this Amendment. The adequacy of the Audit Committee Charter shall be reassessed annually.



The current members
of our Audit Committee are Ms. Deptula-Hicks, Dr. Benz and Mr. Dastoor. Ms. Deptula-Hicks serves as the chairperson of the committee.
All members of our Audit Committee meet the requirements for financial literacy under the applicable rules and regulations of
the SEC and NASDAQ. The Board of Directors has determined that Ms. Deptula-Hicks is an “audit committee financial expert”
within the meaning of applicable regulations adopted by the SEC and has the requisite financial sophistication as defined under
the applicable rules and regulations of NASDAQ. Under the rules of the SEC, members of the Audit Committee must also meet heightened
independence standards. Our Board has determined that each of the members of our Audit Committee is independent under the applicable
rules of NASDAQ and the SEC.



Code of Business Conduct and Ethics



We have adopted
a code of business conduct and ethics that applies to all of our employees, officers and directors, including our principal executive
officer, principal financial officer and principal accounting officer. The code of conduct is available on our website, www.xeneticbio.com,
under “Investors” at “Corporate Governance.” We intend to disclose any amendment to, or waiver of, any
provision of the Code of Business Conduct and Ethics by disclosing such information on our website, to the extent required by
the applicable rules and exchange requirements.

Director Nominations



The Board of Directors
nominates directors for election at each Annual Meeting of Stockholders and appoints new directors to fill vacancies when they
arise. The Nominating and Corporate Governance Committee has the responsibility to identify, evaluate, recruit and recommend qualified
candidates to the Board of Directors for nomination or election.



One of the Board
of Directors’ objectives in evaluating director nominations is to ensure that its membership is composed of experienced
and dedicated individuals with a diversity of backgrounds, perspectives and skills. The Nominating and Corporate Governance Committee
will select nominees for director based on their character, judgment, diversity of experience, business acumen, and ability to
act on behalf of all stockholders. We do not have a formal diversity policy. However, the Nominating and Corporate Governance
Committee endeavors to have a Board representing diverse viewpoints as well as diverse expertise at policy-making levels in many
areas, including business, accounting and finance, healthcare and in other areas that are relevant to our activities.



The Nominating
and Corporate Governance Committee believes it appropriate for at least one, and, preferably, multiple, members of the Board of
Directors to meet the criteria for an “audit committee financial expert” as defined by rules of the SEC, and for a
majority of the members of the Board of Directors to meet the definition of “independent director” as defined by the
NASDAQ Listing Rules. The Nominating and Corporate Governance Committee also believes it appropriate for key members of our management
to participate as members of the Board of Directors.



Prior to each Annual
Meeting of Stockholders, the Nominating and Corporate Governance Committee identifies nominees first by evaluating the current
directors whose term will expire at the Annual Meeting and who are willing to continue in service. These candidates are evaluated
based on the criteria described above, including as demonstrated by the candidate’s prior service as a director, and the
needs of the Board of Directors with respect to the particular talents and experience of its directors. In the event that a director
does not wish to continue in service, the Nominating and Corporate Governance Committee determines not to re-nominate the director,
or a vacancy is created on the Board of Directors as a result of a resignation, an increase in the size of the Board or other
event, the Committee will consider various candidates for Board membership, including those suggested by the Committee members,
by other Board of Directors members, by any executive search firm engaged by the Committee, or by stockholders.



A stockholder who
wishes to suggest a prospective nominee for the Board of Directors should notify Xenetic’s Secretary or any member of the
Committee in writing and include any supporting material the stockholder considers appropriate.   In addition,
our Bylaws contain provisions addressing the process by which a stockholder may nominate an individual to stand for election to
the Board of Directors at our Annual Meeting of Stockholders. In order to nominate a candidate for director, a stockholder must
give timely notice in writing to Xenetic’s Secretary and otherwise comply with the provisions of our Bylaws. To be timely,
our Bylaws provide that we must have received the stockholder’s notice not later than 60 days earlier than 90 days
in advance of the one-year anniversary of the date the proxy statement was released to the stockholders in connection with the
previous year’s Annual Meeting of Stockholders; however, if we have not held an Annual Meeting in the previous year or the
date of the Annual Meeting is changed by more than 30 days from the date contemplated at the time of the mailing of the prior
year’s proxy statement, we must have received the stockholder’s notice not earlier than the close of business on the
90th day prior to such annual meeting and not later than the close of business on the later of the 60th
day prior to such annual meeting or, in the event public announcement of the date of such annual meeting is first made by the
corporation fewer than 70 days prior to the date of such annual meeting, the close of business on the 10th day following
the day on which public announcement of the date of such meeting is first made. Information required by the Bylaws to be in the
notice includes (A) the name, age, business address and residence address of such person, (B) the principal occupation or employment
of such person, (C) the class and number of shares of the corporation which are beneficially owned by such person, (D) a description
of all arrangements or understandings between the stockholder and each nominee and any other person or persons (naming such person
or persons) pursuant to which the nominations are to be made by the stockholder, and (E) any other information relating to such
person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each
case pursuant to Section 14 of the Securities Exchange Act of 1934 and the related rules and regulations under that Section.



Stockholder nominations
must be made in accordance with the procedures outlined in, and include the information required by, our Bylaws and must be addressed
to: Secretary, Xenetic Biosciences, Inc., 99 Hayden Ave, Suite 230, Lexington, Massachusetts 02421. You can obtain a copy of our
Bylaws by writing to the Secretary at this address.

Section 16(a) Beneficial Ownership Reporting Compliance



Section 16(a)
of the Exchange Act requires our directors and executive officers, and persons who own more than ten percent of a registered class
of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of our ordinary
shares and other equity securities. Such persons are required by SEC regulations to furnish us with copies of all Section 16(a)
forms they file



To our knowledge,
based solely on a review of the copies of such reports furnished to us and written representations that no other reports were
required, during the fiscal year ended December 31, 2016, we believe that all Section 16(a) filing requirements applicable
to our executive officers, directors and greater than 10% beneficial owners were complied with, except that one report, covering
an aggregate of one transaction, was filed late by Mr. Maguire; one report, covering an aggregate of two transactions, was filed
late by Mr. Kornberg; one report, covering an aggregate of one transaction, was filed late by Mr. Benz; and one report, covering
an aggregate of one transaction, was filed late by Ms. Deptula-Hicks. Initial reports on Form 3 of ownership were filed late by
Messrs. Eisenberg, Knyazev, Kornberg, Dastoor, Maguire, and Benz and Ms. Deptula-Hicks and Messrs. Knyazev, Dastoor, and Maguire
and Ms. Deptula-Hicks inadvertently did not include all respective holdings on such filings. Our majority shareholder failed to
file a Form 3 after becoming subject to Section 16(a) of the Exchange Act.

|(1) | The amounts represent the aggregate grant date
    fair value of stock options granted in the applicable fiscal year, computed in accordance with FASB ASC Topic 718, excluding
    the effect of estimated forfeitures. Assumptions used in the calculation of this amount are set forth in Note 12 to our audited
    consolidated financial statements included in Part 8 of the Original Filing. Mr. Maguire and Mr. Eisenberg were granted options
    to purchase 250,000 shares and 230,000 shares of common stock, respectively, during 2016. Of these totals, 125,000 and 117,350
    shares, respectively, were granted under our 2014 Equity Incentive Plan while 125,000 and 112,650 shares, respectively, (the
    “Unapproved Portion”) are granted pursuant to the amendment and restatement of our 2014 Equity Incentive Plan,
    such grants subject to forfeiture in the event stockholders fail to approve the new plan. The amounts reflected above represent
    the full fair value of the grants, assuming the Unapproved Portion is approved by our stockholders.

    arrangement, Mr. Maguire earned $13,176 of interest and was granted a warrant to purchase 37,369 shares of our common stock
    at the lesser of $6.60 and 120% of the price per share in our next capital raise of at least $7 million. Mr. Maguire’s

ownership includes any shares over which the individual has sole or shared voting power or investment power as well as any shares
that the individual has the right to acquire within 60 days through the exercise of any stock option, warrants or other rights.
Except as otherwise indicated, and subject to applicable community property laws, the persons named in the table have sole voting
and investment power with respect to all shares of common stock held by that person or entity.



The percentage
of shares beneficially owned is computed on the basis of 8,652,541 shares of our common stock outstanding as of March 31, 2017,
on an as-converted basis. Shares of our common stock that a person has the right to acquire within 60 days after March 31, 2017
are deemed outstanding for purposes of computing the percentage ownership of the person or entity holding such rights, but are
not deemed outstanding for purposes of computing the percentage ownership of any other person, except with respect to the percentage
ownership of all directors and executive officers as a group. Unless otherwise indicated below, the address for each beneficial
owner listed is c/o Xenetic Biosciences, Inc., at 99 Hayden Ave, Suite 230, Lexington, Massachusetts 02421.

ITEM 13 –
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE



During the fiscal
year ended December 31, 2016 and the fiscal year ended December 31, 2015, there was not, nor is there any currently proposed transaction
or series of similar transactions to which Xenetic was or is to be a party in which the amount involved exceeded or exceeds the
lesser of $120,000 or 1% of the average of our total assets at year end for the last two completed fiscal years and in which any
executive officer, director or holder of more than 5% of any class of voting securities of Xenetic and members of that person’s
immediate family had, has or will have a direct or indirect material interest, other than as set forth in “Executive Compensation”
and “Director Compensation Table” above and disclosed below.

Policy Regarding Related Party Transactions



Our Board has adopted
a written related party transaction policy to set forth the policies and procedures for the review and approval or ratification
of related party transactions. Any transaction between the Company and its officers, directors, principal stockholders or affiliates
are required to be on terms no less favorable to us than could be reasonably obtained in arms-length transactions with independent
third-parties, and any such material related party transactions must also be reviewed and approved by a majority of the Board
of Directors. All of the actions described in this section occurred prior to the adoption of this policy.



PJSC Pharmsynthez



PJSC Pharmsynthez
(formerly, OJSC Pharmsynthez) (“Pharmsynthez”) is our largest and controlling stockholder with a share ownership of
52.5% of the total issued and outstanding common stock at March 31, 2017. Pharmsynthez was a related party of SynBio, which is
related party of ours, and acquired 100% of SynBio in February 2017. The combined ownership of Pharmsynthez and SynBio was 62.0%
at March 31, 2017. In addition, one of our directors, Mr. Roman Knyazev, is also a director of Pharmsynthez and one of our executive
officers, Dr. Curtis Lockshin, is an officer of a wholly-owned subsidiary of Pharmsynthez. In November 2009, we entered into a
collaborative research and development license agreement with Pharmsynthez (the “Pharmsynthez Arrangement”) pursuant
to which we granted an exclusive license to Pharmsynthez to develop, commercialize and market six drug candidates based on our
PolyXen and ImuXen technology in certain territories. In exchange, Pharmsynthez granted us an exclusive license to use any pre-clinical
and clinical data developed by Pharmsynthez, within the scope of the Pharmsynthez Arrangement, and to engage in further research,
development and commercialization of drug candidates outside of certain territories at our own expense.



Financing Agreements



In July 2015, we
entered into a Securities Purchase Agreement with Pharmsynthez providing for the issuance of certain promissory notes and certain
warrants to purchase shares of our common stock.



In November 2015,
we entered into the Kevelt APA with AS Kevelt and Pharmsynthez. The Kevelt APA provided for the transfer to us of certain intellectual
property rights with respect to the immunomodulatory drug candidate XBIO-101 held by AS Kevelt. In April 2016, we completed the
purchase of the intellectual property rights associated with the Kevelt APA and issued 3,045,455 shares of common stock pursuant
to the agreement.



The Kevelt APA
also provided for our issuance of certain convertible promissory notes and warrants to purchase shares of our common stock. During
the quarter ended March 31, 2016, we issued $3.5 million of convertible promissory notes to Pharmsynthez receiving $3.5 million
in cash proceeds. In April 2016, Pharmsynthez converted all of its convertible promissory notes (both the July 2015 note and the
Q1 2016 notes) and associated interest of approximately $12.3 million into 1,373,036 shares of common stock. As such, we issued
to Pharmsynthez 1,373,036 shares of common stock in connection with conversion of the convertible notes, which amount, together
with the 3,045,455 shares of common stock in connection with the closing of the Kevelt APA, resulted in an aggregate of 4,418,491
new shares of common stock being issued to Pharmsynthez.



During the quarter
ended September 30, 2016, we issued $1.0 million of convertible promissory notes to Pharmsynthez, receiving $1.0 million in cash
proceeds of which $0.5 million of the notes was applied toward our November 2016 offering. On November 1, 2016, Pharmsynthez purchased
1,454,545 shares of Convertible Series B Preferred Stock in our initial public offering for $6.0 million.



SynBio LLC



SynBio is one of
our largest stockholders and owns approximately 9.5% of our total issued and outstanding common stock as of March 31, 2017 and
all of our outstanding Series A Preferred Stock. Effective February 27, 2017, PJSC Pharmsynthez acquired 100% of SynBio.









10






In August 2011,
we entered into a Co-Development Agreement with SynBio, which is still in effect, pursuant to which we granted an exclusive license
to SynBio to develop pharmaceutical products within Russia and the CIS using certain molecule(s) based on SynBio’s technology
and our proprietary technologies: PolyXen, OncoHist and ImuXen. In return, SynBio granted us an exclusive license to use the pre-clinical
and clinical data generated by SynBio in certain agreed upon products and engage in the development of commercial drug candidates.



The Co-Development
Agreement provides for the sale of certain research supplies between each party to the agreement. For the years ended December 31,
2016 and 2015, we did not recognize any supply service revenues from sales to SynBio about the Co-Development Agreement.



On September 23,
2016, SynBio exchanged 970,000 shares of our common stock for an equal number of shares of Series A Preferred Stock.



Effective October
26, 2016, we entered into a voting agreement with SynBio whereby SynBio agreed to vote their shares of common stock in the same
proportion as the shares of common stock held by non-affiliates on all matters subject to stockholder approval for a period of
one year.



Loan Agreement



In May 2011, we
received a short-term unsecured loan facility of up to $1.7 million from SynBio, of which $0 was outstanding as of December 31,
2016. In connection with the Kevelt APA, we made a series of payments during 2016 totaling $323,640 to creditors of Kevelt. Pursuant
to the Kevelt APA such payments are considered direct offsets to the loan with SynBio. The loan had an interest rate of 8.04%
per annum as of the date of grant, with interest payable upon repayment of the loan, which was to be seven months after the closing
date of the loan. In December 2016, we entered into an agreement with SynBio, Pharmsynthez, and Kevelt, which settled all amounts
owed by us on the SynBio loan; for services provided by Kevelt to us in connection with the XBIO-101 Phase 2 project; and the
purchase of drug candidate supply from Kevelt sufficient to meet the needs of the XBIO-101 Phase 2 clinical trial. Pursuant to
the agreement, we transferred $620,387 to the counterparties. We repaid the remainder of the loan facility with proceeds from
our November 1, 2016 offering.



Serum Institute



Serum Institute
owns approximately 7.3% of our total issued and outstanding common stock at March 31, 2017. In the period from 2004 through 2011,
we entered into certain amended license and supply agreements with Serum Institute. The original license agreement with Serum
Institute was a collaborative Development and Manufacturing Arrangement to develop agreed upon potential commercial product candidates
using our PolyXen technology. Following the 2011 amendment, which is still in effect, Serum Institute retained an exclusive license
to use our PolyXen technology to research and develop one potential commercial product, Polysialylated Erythropoietin (PSA-EPO)
in territories excluding the United States of America, European Economic Area and Japan, among certain other territories. Serum
Institute will be responsible for conducting all pre-clinical and clinical trials required to achieve regulatory approvals within
the certain predetermined territories at Serum Institute’s own expense.



Manufacturing Agreement



The 2011 amendment
with Serum Institute also provides for the supply of PSA by Serum Institute to us and our collaborative partners. Serum Institute
has the non-exclusive right to supply PSA to us, and our collaborative partners and customers on a cost-plus basis. On an individual
basis, Serum Institute may enter into separate supply agreements with us and/or our collaborative partners for the purpose of
providing a supply of PSA directly to the collaborative partners. Further, any agreement between Serum Institute and a collaborative
partner shall not create any obligation or liability for us.



In September 2016,
we issued 211,486 shares of common stock to Serum in exchange for $750,000 of research and development and clinical PSA supply
as well as settlement of approximately $163,000 of prior purchases of PSA supply. During 2015, we paid Serum Institute $115,000
for the supply of PSA or PSA-EPO for use in our ErepoXen human clinical trials being conducted in Australia.



Relationship with Shire plc



As of March 31,
2017, Shire owned approximately 4.6% of our total issued and outstanding common stock. Shire was formerly a related party of ours
in 2015 with share ownership of approximately 8.0% of our total issued and outstanding common stock. We have entered into an exclusive
research, development, license and supply agreement with Shire plc to develop products with an extended half-life of certain proteins
and molecules using our patent protected PolyXen technology whereby PSA is conjugated with Shire’s proprietary molecule(s)
to create a new generation of drugs to treat the failure of blood to coagulate in the therapeutic treatment of blood and bleeding
disorders such as hemophilia. The lead candidate in this collaboration is a longer-acting form of a recombinant Factor VIII (“rFVIII”)
protein (SHP656). The agreement with Shire was originally entered into in August 2005 and has been amended several times, most
recently in January 2014. The 2014 amendment resulted in increased development, regulatory, sales and deadline extension receipts,
restructured target deadlines and royalty receipts on potential net sales. In December 2016, we received a $3 million milestone
payment from Shire related to the advancement of the Phase 1/2 clinical study of SHP656

the January 2014 amendment, we entered into a stock purchase agreement with Shire pursuant to which we sold to Shire 324,097 shares
of our common stock for $10 million. Pursuant to the stock purchase agreement, Shire agreed that until the earlier of (i) three
months after the effective date of a listing of our common stock on the NASDAQ Stock Market or (ii) January 29, 2015
(such earlier date, the Lock-Up Expiration Date), Shire would not assign, transfer, sell or dispose of the Shares to any party
other than a wholly owned subsidiary. In addition, Shire agreed that until the 12-month anniversary of the Lock-Up Expiration
Date, it would not sell or offer to sell any shares of our common stock in an amount that would exceed 15% of the daily trading
volume of Company’s common stock on the principal market or exchange on which the shares of Company’s common stock
are traded, and in no event would Shire sell or offer to sell more than 15% of the Shares in any one month period. In October
2015, Shire agreed in writing not to sell any of its shares currently held before June 30, 2016 and then further to limit the
sale of its shares for an additional six months (to December 2016) to a price of no less than $41.25 per share. Both parties agreed
to waive this limitation in connection with our November 1, 2016 offering.



Director Fees and Consulting Services Agreement with
Dr. Dmitry Genkin



We previously had
entered into an agreement with Dr. Dmitry Genkin under which he was entitled to an annual fee of £750 paid in quarterly
installments for his services as director of the Company. During 2016 and 2015, Dr. Genkin was paid approximately $1,000 annually
in respect of director services provided in each year. In addition, Dr. Genkin provides research and consulting services to the
Company, for which he was paid approximately $129,000 and $73,000 during the years ended December 31, 2016 and 2015, respectively.
In May 2016, Mr. Genkin resigned from our board of directors.



Director Fees and Consulting Services Agreement with
Dr. Timothy R. Coté



We previously had
entered into an agreement with Dr. Timothy R. Coté under which he was entitled to an annual fee of $25,000 paid in
quarterly installments for his services as director of the Company. In addition, his agreement provided for payment of an additional
annual fee of between $3,000 and $10,000 as compensation for attendance at up to four board meetings per year, plus issuance of
options to purchase up to 1,516 shares of our common stock, subject to certain vesting requirements.



During 2015, Dr. Coté
received $18,750 in respect of director services provided and $4,000 for advisory services related to certain orphan drug filings.
In April 2015, Dr. Cote resigned from the board of directors and the consulting agreement was terminated. No consulting services
were provided to us in 2016.



Deferred Salary Arrangement with Mr. M. Scott Maguire



Mr. M. Scott Maguire is our Chief Executive
Officer. Mr. Maguire current annual salary is $456,067 pursuant to his written employment agreement with the Company. Of Mr. Maguire’s
2015 salary amount and 2016 salary through June 30, 2016, fifty percent (50%) has been paid in cash and fifty percent (50%) has
been deferred and accrued pursuant to an unwritten arrangement between us and Mr. Maguire. In July 2016, we issued a 10% Junior
Secured Collateralized Convertible Promissory Note in the amount of $369,958 and warrants to purchase 37,369 shares of our common
stock at the lesser of $6.60 per share and 120% of the price per share in our next capital raise of at least $7 million to Mr.
Maguire for the deferred salary. We also entered into a Deferred Salary Security Agreement with Mr. Maguire, pursuant to which
Mr. Maguire agreed to continue to defer fifty percent (50%) of his salary until the earlier to occur of: (i) the closing of a
public offering of our securities concurrent to a NASDAQ listing, or (ii) September 30, 2016 (the “Deferral End Date”).
All deferred salary shall become due and payable on the Deferral End Date. As security for the payment of the deferred salary,
we granted Mr. Maguire a continuing security interest in our assets, including all inventory, accounts, accounts receivable, equipment,
trademarks, contracts, copyrights and general intangibles, provided, however, that pursuant to a Debt Subordination Agreement
by and between Mr. Maguire and Pharmsynthez, the payment of such deferred salary is subordinate to the prior payment in full in
cash of any and all of our indebtedness and liabilities to Pharmsynthez. Upon completion of our public offering on November 7,
2016, we settled this note and related interest in cash and the Debt Subordination Agreement was terminated.

Director Independence



Under the rules
of NASDAQ Capital Market, independent directors must comprise a majority of a listed company’s board of directors. In addition,
the rules of The NASDAQ Capital Market require that, subject to specified exceptions, each member of a listed company’s
audit, compensation and nominating and corporate governance committees be independent. Under the rules of The NASDAQ Capital Market,
a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors,
that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities
of a director.



Our board of directors
has undertaken a review of the independence of each director and considered whether each director has a material relationship
with us that could compromise his ability to exercise independent judgment in carrying out his responsibilities. As a result of
this review, our board of directors determined that each of Mr. Dastoor, Dr. Kornberg, Ms. Deptula-Hicks and Dr. Benz are independent
directors as defined under the applicable rules and regulations of the SEC, and the listing requirements and rules of The NASDAQ
Capital Market. In making these determinations, our board of directors reviewed and discussed information provided by the directors
and us with regard to each director’s business and personal activities and relationships as they may relate to us and our
management, including the beneficial ownership of our capital stock by each nonemployee director and the transactions involving
them described in the section titled “Certain Relationships and Related Party Transactions.”



Audit committee
members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended
Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company
may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee:
(1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries;
or (2) be an affiliated person of the listed company or any of its subsidiaries. Our board of directors has determined that each
member of our audit committee meets the independence requirements of Rule 10A-3.

Policy

non-audit fee services described above were pre-approved by the Audit Committee.











13






Pursuant to the
Board of Directors’ policy, to help ensure the independence of our independent registered public accounting firm, all auditing
services and permitted non-audit services (including the terms thereof) to be performed for us by our independent registered public
accounting firm must be pre-approved by the Audit Committee, subject to the de-minimis exceptions for non-audit services described
in Section 10A(i)(1)(B) of the Securities Exchange Act of 1934, which are approved by the Audit Committee prior to the commencement
of services.



Our Audit Committee
approved and retained Marcum LLP to audit our consolidated financial statements for 2016. Our Audit Committee reviewed all services
provided by Marcum LLP in 2016 and concluded that the services provided were compatible with maintaining its independence.
