 Exhibit 10.3 

AMENDATORY AGREEMENT 

AMENDATORY AGREEMENT (this “Amendment”), dated as of July 12, 2019, to the Amended and Restated Employment Agreement, dated as of
December 18, 2018, and as further amended (the “Employment Agreement”), between Tower Automotive Operations USA I, LLC, a Delaware limited liability company (the “Company”), and Nanette Dudek (the “Employee”). (The
Company and the Employee are each a “Party” and, collectively, the “Parties”.) 
 RECITALS: 

WHEREAS, pursuant to that certain Agreement and Plan of Merger, dated July 12, 2019, by and among Tower International, Inc., a Delaware
corporation (“Tower”), Autokiniton US Holdings, Inc., a Delaware corporation (“Parent”), and (iii) Tiger Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”) (the “Merger
Agreement”), Merger Sub will commence a cash tender offer (the “Offer”) to purchase any and all of the outstanding shares of common stock of Tower, par value $0.01 per share on the terms set forth in the Merger Agreement and, if such
Offer is consummated, Merger Sub will merge with and into Tower (the “Merger”), with Tower surviving the Merger as a direct, wholly owned Subsidiary of Parent; 

WHEREAS, the Company desires to enter into this Amendatory Agreement in order to induce the Employee to remain employed with the Company and
to afford Employee peace of mind that she will be eligible to receive the full benefits of the Employment Agreement (i) following the Merger, or (ii) in the event that any other “Change in Control” (as defined in the Employment Agreement)
occurs as a result of a definitive transaction agreement entered into by Tower on or before December 31, 2019 (an “Alternative Change in Control Event”); 

WHEREAS, the Parties desire to amend the Employment Agreement to provide that the Employee will be entitled to a retention payment if she
remains employed with Tower or a successor thereto or affiliate thereof for one year following a “Change in Control” (as defined therein); and 

WHEREAS, the Parties desire to further amend the Employment Agreement to provide for a gross-up of any
taxes that may be incurred by the Employee under Section 4999 of the Internal Revenue Code of 1986, as amended, and as a result of any such gross-up payment by virtue of any payments and benefits the
Employee becomes entitled to in connection with or as a result of the Merger or any Alternative Change in Control Event; 
 NOW, THEREFORE,
in consideration of the premises set forth in the above Recitals and other good and valuable consideration, the Parties hereby agree as follows: 

1.    The first two paragraphs of Section 5.3(e) of the Employment Agreement (concerning Section 280G of the
Internal Revenue Code of 1986, as amended) are deleted in their entirety; provided, however, that if (i) the Merger Agreement terminates without consummation of the Merger, and (ii) no Alternative Change in Control Event occurs, then this sentence
shall be void ab initio and Section 5.3(e) of the Employment Agreement shall automatically revert to its terms as in effect immediately prior to the date hereof. For avoidance of doubt, the last three paragraphs of Section 5.3
(concerning compliance with Section 6 of the Employment Agreement and defining “Good Reason”) shall remain in effect. 

2.     “Section 5.6 is hereby added to the Employment Agreement, to read as follows: 

“5.6    Retention Payment. Notwithstanding anything contained herein to the contrary, without
limiting the payments and benefits the Employee may otherwise be entitled to under Sections 5.1, 5.2 or 5.3, the Employee shall be entitled to a “Retention Payment” (as defined below) payable in a single lump sum payment on or within ten
(10) days after the one-year anniversary of a Change in Control (the “CIC Anniversary Date”) if the Employee remains in the employment or service of Tower (or any successor thereto or affiliate
thereof) through such CIC Anniversary Date. 

  
 1 

 
The “Retention Payment” shall be equal to two (2) times the sum of (i) the Employee’s annualized rate of Base Salary in effect on the date of such Change in Control (the
“Retention Salary Component”), and (ii) the Employee’s target bonus for the year in which such Change in Control occurs (the “Retention Bonus Component”). If the Employee terminates employment after the CIC Anniversary
Date but on or before the two-year anniversary of such Change in Control, and becomes entitled to payments and/or benefits under Section 5.3, then the Employee shall be entitled to receive all amounts and
benefits set forth in Section 5.3 except that the CIC Base Severance Amount and the CIC Bonus Severance Amount under Section 5.3 shall be reduced, respectively, by the Retention Salary Component and the Retention Bonus Component. For
avoidance of doubt, without limiting any other amounts or benefits that the employee becomes entitled to under Section 5.3, if the preceding sentence applies, the Employee shall be entitled to payment of a
pro-rated bonus for the year of termination in accordance with Section 5.3(b)(i)(B) without reduction or offset for any portion of the Retention Payment. If the Employee terminates employment after the two-year anniversary of the CIC Anniversary Date, no amounts or benefits that the Employee may be entitled to under Sections 5.2 or 5.3 shall be reduced or offset by the Retention Payment. The Retention Payment
shall be subject to applicable income and payroll tax withholdings and other authorized deductions. 
 The Company may
condition the Retention Payment upon the Employee’s execution (and non-revocation) of a Release; provided that the Release is furnished to the Employee at least
twenty-one (21) days prior to the CIC Anniversary Date.” 

3.    Section 5.7 is hereby added to the Employment Agreement, to read as set forth below; provided, however, that if (i)
the Merger Agreement terminates without consummation of the Merger, and (ii) no Alternative Change in Control Event occurs, then the amendment set forth in this paragraph 3 shall be void ab initio: 

“5.7    Tax Gross-up. Notwithstanding any other
provision of this Agreement or any other plan, arrangement or agreement to the contrary, if any of the payments or benefits provided or to be provided by the Company or its affiliates to the Employee or for the Employee’s benefit pursuant to
the terms of this Agreement or otherwise (“Covered Payments”) constitute parachute payments (“Parachute Payments”) within the meaning of Section 280G of the Code and will be subject to the excise tax imposed under
Section 4999 of the Code (or any successor provision thereto) or any interest or penalties with respect to such excise tax (collectively, the “Excise Tax”), then the Company shall pay to the Employee, no later than the time the Excise
Tax is required to be paid by the Employee or withheld by the Company, an additional amount (the “Gross-up Payment”) equal to the sum of the Excise Tax payable by the Employee, plus the amount
necessary to put the Employee in the same after-tax position (taking into account any and all applicable federal, state, local and foreign income, employment and excise taxes (including the

  
 2 

 
Excise Tax and any income and employment taxes imposed on the Gross-up Payment)) that the Employee would have been in if the Employee had not incurred any
tax liability under Section 4999 of the Code. 
 The determination of whether a
Gross-up Payment will be required, and of the amount of such Gross-up Payment, shall initially be made (at the Company’s expense) by a nationally recognized
registered public accounting firm reasonably acceptable to the Company and the Employee prior to the time the Excise Tax is required to be paid by the Employee or withheld by the Company, and shall be made applying the assumptions that the Employee
will pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the Gross-up Payment is to be made, and state and local income
taxes at the highest marginal rates of individual taxation in the state and locality of Executive’s residence at the time. In light of the uncertainty in applying Sections 280G and 4999 of the Code, if it is subsequently determined that the Gross-up Payment is not sufficient to put the Employee in the same after-tax position (taking into account any and all applicable federal, state, local and foreign income,
employment and excise taxes (including the Excise Tax and such taxes imposed on the Gross-up Payment)) that the Employee would have been in if the Employee had not incurred the Excise Tax, then the Company
shall promptly pay to or for the benefit of the Employee such additional amounts necessary to put the Employee in the same after-tax position that the Employee would have been in if the Excise Tax had not been
imposed. In the event that a written ruling of the Internal Revenue Service (“IRS”) is obtained by or on behalf of the Company or the Employee, which provides that the Employee is not required to pay, or is entitled to a refund with
respect to, all or a portion of the Excise Tax, then the Employee shall reimburse the Company in an amount equal to the Gross-up Payment, less any amounts which remain payable by or are not refunded to the
Employee, within thirty (30) days of the date of the IRS determination or the date the Employee receives the refund, as applicable. The Employee and the Company shall reasonably cooperate with each other in connection with any administrative or
judicial proceedings concerning the existence or amount of liability for the Excise Tax; provided that, if the Company decides to contest a claim by the IRS relating to the Excise Tax, then the Company shall bear and pay directly or indirectly all
costs and expenses (including any additional interest and penalties and any legal and accounting fees and expenses) incurred in connection with such action and shall indemnify and hold the Employee harmless, on an
after-tax basis, for any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of the Company’s action.” 

4.    Miscellaneous. This Amendment, together with the Employment Agreement, constitutes the entire agreement
between the Parties with respect to the subject matter hereof and supersedes any prior understandings, agreements, or 

  
 3 

 
representations by or between the Parties, written or oral, that may have related in any way to the subject matter hereof. This Amendment shall be binding upon and inure to the benefit of the
Parties and their respective successors and permitted assigns. No amendment or waiver of any provision of this Amendment shall be valid unless the same shall be in writing and signed by each Party bound thereby. This Amendment may be executed by the
Parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Delivery of an executed counterpart of this Amendment by facsimile or pdf
email transmission shall be effective as delivery of a manually executed counterpart hereof.

Section 2. Exercise.

a) Exercise of
Warrant. Subject to the provisions of Section 2(e) herein, exercise of the purchase rights represented by this Warrant
may be made, in whole or in part, at any time or times on or after the Initial Exercise Date and on or before the Termination
Date by delivery to the Company of a duly executed facsimile copy or PDF copy submitted by e-mail (or e-mail attachment) of
the Notice of Exercise in the form annexed hereto (the "Notice of Exercise"). Within the earlier of (i) two
(2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period (as defined in Section 2(d)(i)
herein) following the date of exercise as aforesaid, the Holder shall deliver the aggregate Exercise Price for the Warrant
Shares specified in the applicable Notice of Exercise by wire transfer or cashier's check drawn on a United States
bank unless the cashless exercise procedure specified in Section 2(c) below is specified in the applicable Notice of
Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee
or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not
be required to physically surrender this Warrant to the Company until the Holder has purchased all of the Warrant Shares
available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the
Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the
Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares
available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an
amount equal to the applicable number of Warrant Shares purchased. The Holder and the Company shall maintain records showing
the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice
of Exercise within one (1) Trading Day of receipt of such notice. The Holder and any assignee, by acceptance of this
Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of
the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less
than the amount stated on the face hereof.

b) Exercise
Price. The aggregate exercise price of this Warrant, except for a nominal exercise price of $0.01 per Warrant Share, was
pre-funded to the Company on or prior to the Initial Exercise Date and, consequently, no additional consideration (other than
the nominal exercise price of $0.01 per Warrant Share) shall be required to be paid by the Holder to any Person to effect any
exercise of this Warrant. The Holder shall not be entitled to the return or refund of all, or any portion, of such pre-paid
aggregate exercise price under any circumstance or for any reason whatsoever, including in the event this Warrant shall not
have been exercised prior to the Termination Date. The remaining unpaid exercise price per share of Common Stock under this
Warrant shall be $0.01, subject to adjustment hereunder (the "Exercise Price").

c) Cashless
Exercise. If at the time of exercise hereof there is no effective registration statement registering, or the prospectus contained
therein is not available for the issuance of the Warrant Shares to the Holder, then this Warrant may also be exercised, in whole
or in part, at such time by means of a "cashless exercise" in which the Holder shall be entitled to receive a number
of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = as applicable:
(i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise
is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and
delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of "regular trading hours" (as defined
in Rule 600(b)(64) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii) at the option of
the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the
Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder's execution
of the applicable Notice of Exercise if such Notice of Exercise is executed during "regular trading hours" on a Trading
Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of "regular trading hours"
on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date
of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a)
hereof after the close of "regular trading hours" on such Trading Day;

(B) = the Exercise
Price of this Warrant, as adjusted hereunder; and

(X) = the number of
Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise
were by means of a cash exercise rather than a cashless exercise.

If Warrant Shares are
issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities
Act, the Warrant Shares shall take on the registered characteristics of the Warrants being exercised. The Company agrees not to
take any position contrary to this Section 2(c).

 

 

 

    
	 	2	 

     

    

 

d) Mechanics
of Exercise.

i. Delivery of
Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the
Transfer Agent to the Holder by crediting the account of the Holder's or its designee's balance account with The Depository
Trust Company through its Deposit or Withdrawal at Custodian system ("DWAC") if the Company is then a
participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant
Shares to or resale of the Warrant Shares by the Holder or (B) this Warrant is being exercised via cashless exercise,
and otherwise by physical delivery of a certificate, registered in the Company's share register in the name of the Holder or
its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address
specified by the Holder in the Notice of Exercise by the date that is the earliest of (i) two (2) Trading Days after the
delivery to the Company of the Notice of Exercise, (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to
the Company and (iii) the number of Trading Days comprising the Standard Settlement Period after the delivery to the Company
of the Notice of Exercise (such date, the "Warrant Share Delivery Date"). Upon delivery of the Notice of
Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares
with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided
that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within the
earlier of (i) two (2) Trading Days and (ii) the number of Trading Days comprising the Standard Settlement Period following
delivery of the Notice of Exercise. If the Company fails for any reason to deliver to the Holder the Warrant Shares subject
to a Notice of Exercise by the Warrant Share Delivery Date, the Company shall pay to the Holder, in cash, as liquidated
damages and not as a penalty, for each $1,000 of Warrant Shares subject to such exercise (based on the VWAP of the Common
Stock on the date of the applicable Notice of Exercise), $10 per Trading Day (increasing to $20 per Trading Day on the fifth
(5th)Trading Day after such liquidated damages begin to accrue) for each Trading Day after such Warrant Share Delivery
Date until such Warrant Shares are delivered or Holder rescinds such exercise. The Company agrees to maintain a transfer
agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable. As used herein,
"Standard Settlement Period" means the standard settlement period, expressed in a number of Trading Days, on
the Company's primary Trading Market with respect to the Common Stock as in effect on the date of delivery of the Notice of
Exercise. Notwithstanding the foregoing, with respect to any Notice(s) of Exercise delivered on or prior to 12:00 p.m. (New
York City time) on the Initial Exercise Date, which may be delivered at any time after the time of execution of the
Underwriting Agreement, dated [___________], 2019 between the Company and Maxim Group LLC, the Company agrees to deliver the
Warrant Shares subject to such notice(s) by 4:00 p.m. (New York City time) on the Initial Exercise Date and the Initial
Exercise Date shall be the Warrant Share Delivery Date for purposes hereunder.

ii. Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request
of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder
a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which
new Warrant shall in all other respects be identical with this Warrant.

iii. Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to
Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise.

iv. Compensation
for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise. In addition to any other rights available
to the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares in accordance
with the provisions of Section 2(d)(i) above pursuant to an exercise on or before the Warrant Share Delivery Date (other than
any such failure that is solely due to any action or inaction by the Holder with respect to such exercise), and if after such
date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder's brokerage
firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant Shares
which the Holder anticipated receiving upon such exercise (a "Buy-In"), then the Company shall (A) pay in
cash to the Holder the amount, if any, by which (x) the Holder's total purchase price (including brokerage commissions, if
any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant
Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (2) the price at
which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either
reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in
which case such exercise shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would
have been issued had the Company timely complied with its exercise and delivery obligations hereunder. For example, if the
Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted
exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of $10,000, under
clause (A) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder
shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In and, upon
request of the Company, evidence of the amount of such loss. Nothing herein shall limit a Holder's right to pursue any other
remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief with respect to the Company's failure to timely deliver shares of Common Stock upon exercise of the
Warrant as required pursuant to the terms hereof.

 

 

    
	 	3	 

     

    

 

v. No Fractional
Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the
Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such
fraction multiplied by the Exercise Price or round up to the next whole share.

vi. Charges,
Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or
other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the
Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder;
provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the
Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by
the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer
tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise
and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required
for same-day electronic delivery of the Warrant Shares.

vii. Closing of
Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of
this Warrant, pursuant to the terms hereof.

e) Holder's
Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have
the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect
to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder's
Affiliates, and any other Persons acting as a group together with the Holder or any of the Holder's Affiliates (such Persons,
"Attribution Parties")), would beneficially own in excess of the Beneficial Ownership Limitation (as defined
below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its
Affiliates and Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant
with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be
issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder
or any of its Affiliates or Attribution Parties and (ii) exercise or conversion of the unexercised
or nonconverted portion of any other securities of the Company (including, without limitation, any other Common
Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained
herein beneficially owned by the Holder or any of its Affiliates or Attribution Parties. Except as set forth in the preceding
sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the
Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is
not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder
is solely responsible for any schedules required to be filed in accordance therewith. To the extent that the limitation
contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other
securities owned by the Holder together with any Affiliates and Attribution Parties) and of which portion of this Warrant is
exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be
the Holder's determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder
together with any Affiliates and Attribution Parties) and of which portion of this Warrant is exercisable, in each case
subject to the Beneficial Ownership Limitation, and the Company shall have no obligation to verify or confirm the accuracy of
such determination. In addition, a determination as to any group status as contemplated above shall be determined in
accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. For purposes of this
Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding
shares of Common Stock as reflected in (A) the Company's most recent periodic or annual report filed with the Commission, as
the case may be, (B) a more recent public announcement by the Company or a more recent written notice by the Company or the
Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of a Holder,
the Company shall within one Trading Day confirm orally and in writing to the Holder the number of shares of Common Stock
then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to
the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates or
Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The
"Beneficial Ownership Limitation" shall be 4.99% (or, upon election by a Holder prior to the issuance of any
Warrants, 9.99%) of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of
shares of Common Stock issuable upon exercise of this Warrant. The Holder, upon notice to the Company, may increase or
decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership
Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect
to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section
2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61st day
after such notice is delivered to the Company. The provisions of this paragraph shall be construed and implemented in a
manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion
hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make
changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this
paragraph shall apply to a successor holder of this Warrant.

Section 3. Certain
Adjustments.

a) Stock
Dividends and Splits. If the Company, at any time while this Warrant is outstanding: (i) pays a stock dividend or
otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent
securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock
issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number
of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number
of shares, or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then
in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall
be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon
exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall
remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date
for the determination of stockholders entitled to receive such dividend or distribution and shall become effective
immediately after the effective date in the case of a subdivision, combination or re-classification.

b) Subsequent
Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company
grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro
rata to all (or substantially all) of the record holders of any class of shares of Common Stock (the "Purchase
Rights"), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the
aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock
acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without
limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant,
issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares
of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, to the extent
that the Holder's right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial
Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or
beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase
Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result
in the Holder exceeding the Beneficial Ownership Limitation).

c) Pro Rata
Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or
other distribution of its assets (or rights to acquire its assets) to all (or substantially all) of holders of shares of
Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or
other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of
arrangement or other similar transaction) (a "Distribution"), at any time after the issuance of this
Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that
the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon
complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the
Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such
record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation
in such Distribution (provided, however, to the extent that the Holder's right to participate in any such
Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled
to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result
of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the
Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership
Limitation).

d) Fundamental
Transaction. Other than the issuance of securities in connection with (A) the Company's public offering pursuant to which
this Warrant is being issued, which offering was registered on Registration Statement on Form S-1, Registration No.
333-231508 (the "Form S-1") and (B) the Transaction as defined in and described in the Form S-1, if at any time
while this Warrant is outstanding, (i) the Company, directly or indirectly, in one or more related transactions effects any
merger or consolidation of the Company with or into another Person, (ii) the Company, directly or indirectly, effects any
sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one
or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer (whether
by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or
exchange their shares for other securities, cash or property and has been accepted by the holders of 50% or more of the
outstanding Common Stock, (iv) the Company, directly or indirectly, in one or more related transactions effects any
reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which
the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company,
directly or indirectly, in one or more related transactions consummates a stock or share purchase agreement or other business
combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with
another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares
of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or
associated or affiliated with the other Persons making or party to, such stock or share purchase agreement or other business
combination) (each a "Fundamental Transaction"), then, upon any subsequent exercise of this Warrant, the
Holder shall have the right to receive, for each Warrant Share that would have been issuable upon such exercise immediately
prior to the occurrence of such Fundamental Transaction, at the option of the Holder (without regard to any limitation in
Section 2(e) on the exercise of this Warrant), the number of shares of Common Stock of the successor or acquiring corporation
or of the Company, if it is the surviving corporation, and any additional consideration (the "Alternate
Consideration") receivable as a result of such Fundamental Transaction by a holder of the number of shares of Common
Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any
limitation in Section 2(e) on the exercise of this Warrant). For purposes of any such exercise, the determination of the
Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate
Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the Company shall
apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any
different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities,
cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the
Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction. The
Company shall cause any successor entity in a Fundamental Transaction in which the Company is not the survivor (the
"Successor Entity") to assume in writing all of the obligations of the Company under this Warrant in
accordance with the provisions of this Section 3(d) pursuant to written agreements in form and substance reasonably
satisfactory to the Holder prior to such Fundamental Transaction and shall, at the option of the Holder, deliver to the
Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially
similar in form and substance to this Warrant which is exercisable for a corresponding number of shares of capital stock of
such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise
of this Warrant (without regard to any limitations on the exercise of this Warrant) prior to such Fundamental Transaction,
and with an exercise price which applies the exercise price hereunder to such shares of capital stock (but taking into
account the relative value of the shares of Common Stock pursuant to such Fundamental Transaction and the value of such
shares of capital stock, such number of shares of capital stock and such exercise price being for the purpose of protecting
the economic value of this Warrant immediately prior to the consummation of such Fundamental Transaction), and which is
reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Fundamental Transaction, the
Successor Entity shall succeed to, and be substituted for (so that from and after the date of such Fundamental
Transaction, the provisions of this Warrant referring to the "Company" shall refer instead to the Successor
Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under
this Warrant with the same effect as if such Successor Entity had been named as the Company herein. For the avoidance of
doubt, if, at any time while this Warrant is outstanding, a Fundamental Transaction occurs, pursuant to the terms of this
Section 3(d), the Holder shall not be entitled to receive more than one of (i) the consideration receivable as a result of
such Fundamental Transaction by a holder of the number of shares of Common Stock for which this Warrant is exercisable
immediately prior to such Fundamental Transaction, or (ii) the assumption by the Successor Entity of all of the obligations
of the Company under this Warrant and the option to receive a security of the Successor Entity evidenced by a written
instrument substantially similar in form and substance to this Warrant.

e) [Reserved.]

f) Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may
be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given
date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

g) Notice to
Holder.

i. Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
deliver to the Holder by facsimile or email a notice setting forth the Exercise Price after such adjustment and any resulting adjustment
to the number of Warrant Shares and setting forth a brief statement of the facts requiring such adjustment.

ii. Notice to
Allow Exercise by Holder. If (A) the Company shall declare a dividend (or any other distribution in whatever form) on the
Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C)
the Company shall authorize the granting to all holders of the Common Stock rights or warrants to subscribe for or purchase
any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be
required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a
party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange
whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the
voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the
Company shall cause to be delivered by facsimile or email to the Holder at its last facsimile number or email address as it
shall appear upon the Warrant Register of the Company, at least twenty (20) calendar days prior to the applicable record or
effective date hereinafter specified, a notice (unless such information is filed with the Commission, in which case a notice
shall not be required) stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution,
redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of
record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on
which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or
close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their
shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation,
merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the
delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent
that any notice provided in this Warrant constitutes, or contains, material, non-public information regarding the Company or
any of the Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current
Report on Form 8-K. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of
such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth
herein.

Section 4. Transfer of
Warrant.

a) Transferability.
This Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the principal
office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form
attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable
upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a
new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations
specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this
Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the
Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant
in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on
which the Holder delivers an assignment form to the Company assigning this Warrant in full. The Warrant, if properly assigned
in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant
issued.

b) New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of
the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued,
signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the
Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges
shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of
Warrant Shares issuable pursuant thereto.

c) Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose
(the "Warrant Register"), in the name of the record Holder hereof from time to time. The Company may
deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or
any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

Section 5. Miscellaneous.

a) No Rights
as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting
rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section
2(d)(i), except as expressly set forth in Section 3. Without limiting the rights of a Holder to receive Warrant Shares
on a "cashless exercise," and to receive the cash payments contemplated pursuant to Sections 2(d)(i) and
2(d)(iv), in no event will the Company be required to net cash settle a Warrant exercise.

b) Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence
reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating
to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it
(which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such
Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like
tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

c) Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required
or granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next
succeeding Business Day.

d) Authorized
Shares.

The Company covenants
that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient
number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant.
The Company further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged
with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without
violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be
listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented
by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance
herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges
created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously
with such issue).

Except and to the extent
as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate
of incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities
or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will
at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary
or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality
of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon
such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in
order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of
this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public
regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action
which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price,
the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

e) Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be
governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the
principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Warrant (whether brought against a party hereto or their
respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced
exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the
exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the
adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an
inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to
process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or
overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Warrant
and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained
herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party
shall commence an action, suit or proceeding to enforce any provisions of this Warrant, the prevailing party in such action,
suit or proceeding shall be reimbursed by the other party for their reasonable attorneys' fees and other costs and expenses
incurred with the investigation, preparation and prosecution of such action or proceeding. Notwithstanding the foregoing,
nothing in this paragraph shall limit or restrict the federal district court in which a Holder may bring a claim under the
federal securities laws.

 

 

    
	 	8	 

     

    

 

f) Restrictions.
The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered, and the
Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities
laws.

g) Nonwaiver and
Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall
operate as a waiver of such right or otherwise prejudice the Holder's rights, powers or remedies. Without limiting any other
provision of this Warrant, if the Company willfully and knowingly fails to comply with any provision of this Warrant, which
results in any material damages to the Holder, the Company shall pay to the Holder such amounts as shall be sufficient to
cover any costs and expenses including, but not limited to, reasonable attorneys' fees, including those of appellate
proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its
rights, powers or remedies hereunder.

h) Notices.
Any and all notices or other communications or deliveries to be provided by the Holders hereunder including, without
limitation, any Notice of Exercise, shall be in writing and delivered personally, by facsimile or e-mail, or sent by a
nationally recognized overnight courier service, addressed to the Company, at 40 Speen Street, Suite 102,
Framingham, Massachusetts 01701, Attention: Chief Executive Officer, facsimile number [ ], E-mail: info@xeneticbio.com, or
such other facsimile number, email address or address as the Company may specify for such purposes by notice to the Holders.
Any and all notices or other communications or deliveries to be provided by the Company hereunder shall be in writing and
delivered personally, by facsimile or e-mail, or sent by a nationally recognized overnight courier service addressed to each
Holder at the facsimile number, e- mail address or address of such Holder appearing on the books of the Company. Any notice
or other communication or deliveries hereunder shall be deemed given and effective on the earliest of (i) the time of
transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at the e-mail
address set forth in this Section prior to 5:30 p.m. (New York City time) on any date, (ii) the next Trading Day after the
time of transmission, if such notice or communication is delivered via facsimile at the facsimile number or via e-mail at the
e-mail address set forth in this Section on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on
any Trading Day, (iii) the second Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight
courier service, or (iv) upon actual receipt by the party to whom such notice is required to be given. To the extent that any
notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any
Subsidiaries, the Company shall simultaneously file such notice with the Commission pursuant to a Current Report on Form
8-K.

i) Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to
purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any
liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability
is asserted by the Company or by creditors of the Company.

j) Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be
entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be
adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees
to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

k) Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall
inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and
permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to
time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

l) Amendment.
This Warrant may be modified or amended or the provisions hereof waived with the written consent of the Company, on the one
hand, and the Holder, on the other hand.

m) Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions
or the remaining provisions of this Warrant.

n) Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.
