1.2           Purpose.
The purpose of the Plan is to advance the interests of the Participating Company Group and its stockholders by providing an
incentive to attract, retain and reward persons performing services for the Participating Company Group and by motivating such
persons to contribute to the growth and profitability of the Participating Company Group.

of Plan. The Plan shall continue in effect until the earlier of its termination by the Board or the date on which all of the
shares of Stock available for issuance under the Plan have been issued and all restrictions on such shares under the terms of the
Plan and the agreements evidencing Awards granted under the Plan have lapsed. However, all Awards shall be granted, if at all,
within ten (10) years from the earlier of the date the Plan is adopted by the Board or the date the Plan is duly approved
by the stockholders of the Company. The Company intends that the Plan comply with Section 409A of the Code, including any amendments
or replacements of such section, and the Plan shall be so construed.

 

2.           Definitions

(b)          "Assumed
" means that pursuant to a Corporate Transaction either (i) an Award is expressly affirmed by the Company or

entity or its parent in connection with the Corporate Transaction, with appropriate adjustments to the number and type of securities
of the successor entity or its parent subject to the Award and the exercise or purchase price thereof, which at least preserves
the compensation element of the Award existing at the time of the Corporate Transaction, as determined in accordance with the instruments

with any appeal thereof, to which they or any of them may be a party by reason of any action taken or failure to act under or in

has a material effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the
number and class of shares subject to the Plan and to any outstanding Options, in the ISO Share Limit set forth in Section 4.1,
and in the exercise price per share of any outstanding Options in order to prevent dilution or enlargement of Optionees' rights
under the Plan. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as
"effected without receipt of consideration by the Company." Any fractional share resulting from an adjustment pursuant
to this Section 4.2 shall be rounded down to the nearest whole number, and in no event may the exercise price of any Option
be decreased to an amount less than the par value, if any, of the stock subject to the Option. Such adjustments shall be determined
by the Board, and its determination shall be final, binding and conclusive.

 

5.           Eligibility
and Option Limitations.

 

5.1           Persons
Eligible for Awards. Awards may be granted only to Employees and Consultants. For purposes of the foregoing sentence,
"Employees" and "Consultants" shall include prospective Employees and prospective Consultants to whom Options
are granted in connection with written offers of an employment or other service relationship with the Participating Company Group.
Eligible persons may be granted more than one (1) Award. However, eligibility in accordance with this Section shall not entitle
any person to be granted an Award, or, having been granted an Award, to be granted an additional Award.

 

5.2           Option
Grant Restrictions.  An Incentive Stock Option may be granted only to a person who is an Employee on the effective date
of grant of the Option to such person. Any person who is not an Employee on the effective date of the grant of an Option to such
person may only be granted a Nonstatutory Stock Option. An Incentive Stock Option granted to a prospective Employee upon the condition
that such person become an Employee shall be deemed granted effective on the date such person commences Service with a Participating
Company, with an exercise price determined as of such date in accordance with Section 6.1.

 

    	10

    	 

    

  

5.3           Fair
Market Value Limitation. To the extent that Options designated as Incentive Stock Options (granted under all stock plans
of the Participating Company Group, including the Plan) become exercisable by a Participant for the first time during any calendar
year for stock having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portions of such Options which
exceed such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section 5.3, Options designated as
Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of stock
shall be determined as of the time the Option with respect to such stock is granted. If the Code is amended to provide for a different
limitation from that set forth in this Section 5.3, such different limitation shall be deemed incorporated herein effective
as of the date and with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated
as an Incentive Stock Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this Section 5.3,
the Participant may designate which portion of such Option the Participant is exercising. In the absence of such designation, the
Participant shall be deemed to have exercised the Incentive Stock Option portion of the Option first. Separate certificates representing
each such portion shall be issued upon the exercise of the Option.

 

6.           Terms
and Conditions of Options.

 

Options shall be evidenced by Option Agreements
specifying the number of shares of Stock covered thereby, in such form as the Board shall from time to time establish. No Option
or purported Option shall be a valid and binding obligation of the Company unless evidenced by a fully executed Option Agreement.
Option Agreements may incorporate all or any of the terms of the Plan by reference and shall be subject to the following terms
and conditions:

 

6.1           Exercise
Price. The exercise price for each Option shall be established in the discretion of the Board, subject to compliance
with Section 409A of the Code; provided, however, that (a) the exercise price per share for an Incentive Stock Option shall
be not less than the Fair Market Value of a share of Stock on the effective date of grant of the Option, (b) the exercise
price per share for a Nonstatutory Stock Option shall be not less than the Fair Market Value of a share of Stock on the effective
date of grant of the Option, and (c) no Option granted to a Ten Percent Stockholder shall have an exercise price per share
less than one hundred ten percent (110%) of the Fair Market Value of a share of Stock on the effective date of grant of the Option.
Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Nonstatutory Stock Option) may be granted with
an exercise price lower than the minimum exercise price set forth above if such Option is granted pursuant to an assumption or
substitution for another option in a manner qualifying under the provisions of Section 424(a) of the Code.

 

6.2           Exercisability
and Term of Options.  Options shall be exercisable at such time or times, or upon such event or events, and subject
to such terms, conditions, performance criteria and restrictions as shall be determined by the Board and set forth in the Option
Agreement evidencing such Option; provided, however, that, (a) no Option shall be exercisable after the expiration of ten
(10) years after the effective date of grant of such Option, (b) no Incentive Stock Option granted to a Ten Percent Stockholder
shall be exercisable after the expiration of five (5) years after the effective date of grant of such Option, and (c) no Option
granted to a prospective Employee or prospective Consultant may become exercisable prior to the date on which such person commences
Service with a Participating Company. Subject to the foregoing, unless otherwise specified by the Board in the grant of an Option,
any Option granted hereunder shall terminate ten (10) years after the effective date of grant of the Option, unless earlier terminated
in accordance with its provisions.

 

    	11

    	 

    

 

6.3           Payment
of Exercise Price.

 

(a)          Forms
of Consideration Authorized. Except as otherwise provided below, payment of the exercise price for the number of shares
of Stock being purchased pursuant to any Option shall be made (i) in cash, by check or cash equivalent, (ii) by tender
to the Company, or attestation to the ownership, of shares of Stock owned by the Participant having a Fair Market Value not less
than the exercise price, (iii) by delivery of a properly executed notice together with irrevocable instructions to a broker
providing for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares being acquired
upon the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T
as promulgated from time to time by the Board of Governors of the Federal Reserve System) (a "Cashless Exercise"),
(iv) by such other consideration as may be approved by the Board from time to time to the extent permitted by applicable law,
or (v) by any combination thereof. The Board may at any time or from time to time, by approval of or by amendment to the standard
forms of Option Agreement described in Section 8, or by other means, grant Options which do not permit all of the foregoing
forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration.
Notwithstanding any other provision of the Plan to the contrary, no Optionee who is a Director or an "executive officer"
of the Company within the meaning of Section 13(k) of the Exchange Act shall be permitted to make payment with respect to any Options
granted under the Plan, or continue any extension of credit with respect to such payment with a loan from the Company or a loan
arranged by the Company in violation of Section 13(k) of the Exchange Act.

 

(b)          Limitations
on Forms of Consideration.

 

(i)          Tender
of Stock. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company, or attestation to the ownership,
of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any law, regulation
or agreement restricting the redemption of the Company's stock. Unless otherwise provided by the Board, an Option may not be exercised
by tender to the Company, or attestation to the ownership, of shares of Stock unless such shares either have been owned by the
Participant for more than six (6) months (and were not used for another Option exercise by attestation during such period) or were
not acquired, directly or indirectly, from the Company.

 

(ii)         Cashless
Exercise. The Board reserves, at any and all times, the right, in the Board's sole and absolute discretion, to establish, decline
to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise.

 

6.4           Effect
of Termination of Service.

 

(a)          Option
Exercisability. Subject to earlier termination of the Option as otherwise provided herein, and unless otherwise provided
by the Board in the grant of an Option and set forth in the Option Agreement, an Option shall be exercisable after a Participant's
termination of Service only during the applicable time period determined in accordance with this Section 6.4 and thereafter
shall terminate:

 

    	12

    	 

    

  

(i)          Disability.
If the Participant's Service terminates because of the Disability of the Participant, the Option, to the extent unexercised and
exercisable on the date on which the Participant's Service terminated, may be exercised by the Participant (or the Participant's
guardian or legal representative) at any time prior to the expiration of twelve (12) months (or such longer period of time as determined
by the Board, in its discretion) after the date on which the Participant's Service terminated, but in any event no later than the
date of expiration of the Option's term as set forth in the Option Agreement evidencing such Option (the "Option
Expiration Date").

 

(ii)         Death.
If the Participant's Service terminates because of the death of the Participant, the Option, to the extent unexercised and exercisable
on the date on which the Participant's Service terminated, may be exercised by the Participant's legal representative or other
person who acquired the right to exercise the Option by reason of the Participant's death at any time prior to the expiration of
twelve (12) months (or such longer period of time as determined by the Board, in its discretion) after the date on which the Participant's
Service terminated, but in any event no later than the Option Expiration Date. The Participant's Service shall be deemed to have
terminated on account of death if the Participant dies within three (3) months (or such longer period of time as determined by
the Board, in its discretion) after the Participant's termination of Service.

 

(iii)        Termination
for Cause. Notwithstanding any other provision of the Plan to the contrary, if the Participant's Service with the Participating
Company Group is terminated for Cause, as defined by the Participant's Option Agreement or contract of employment or service (or,
if not defined in any of the foregoing, as defined below), the Option shall terminate and cease to be exercisable immediately upon
such termination of Service.

 

(iv)         Other
Termination of Service. If the Participant's Service terminates for any reason, except Disability, death or Cause, the Option,
to the extent unexercised and exercisable by the Participant on the date on which the Participant's Service terminated, may be
exercised by the Participant at any time prior to the expiration of six (6) months (or such longer period of time as determined
by the Board, in its discretion) after the date on which the Participant's Service terminated, but in any event no later than the
Option Expiration Date.

 

(b)          Extension
if Exercise Prevented by Law. Notwithstanding the foregoing other than termination for Cause, if the exercise of an Option
within the applicable time periods set forth in Section 6.4(a) is prevented by the provisions of Section 11 below, the
Option shall remain exercisable until three (3) months (or such longer period of time as determined by the Board, in its discretion)
after the date the Participant is notified by the Company that the Option is exercisable, but in any event no later than the Option
Expiration Date.

 

    	13

    	 

    

  

(c)          Extension
if Participant Subject to Section 16(b). Notwithstanding the foregoing other than termination for Cause, if a sale
within the applicable time periods set forth in Section 6.4(a) of shares acquired upon the exercise of the Option would subject
the Participant to suit under Section 16(b) of the Exchange Act, the Option shall remain exercisable until the earliest to
occur of (i) the tenth (10th) day following the date on which a sale of such shares by the Participant would no longer be
subject to such suit, (ii) the one hundred and ninetieth (190th) day after the Participant's termination of Service, or (iii) the
Option Expiration Date.

 

6.5           Transferability
of Options. During the lifetime of the Participant, an Option shall be exercisable only by the Participant or the Participant's
guardian or legal representative. No Option shall be assignable or transferable by the Participant, except by will or by the laws
of descent and distribution. No Option or interest or right therein shall be liable for the debts, contracts or engagements of
the Participant or his successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge,
hypothecation, encumbrance, assignment or any other means whether such disposition be voluntary or involuntary or by operation
of law by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted
disposition thereof shall be null and void and of no effect. Notwithstanding the foregoing, to the extent permitted by the Board,
in its discretion, and set forth in the Option Agreement evidencing such Option, a Nonstatutory Stock Option shall be assignable
or transferable subject to the applicable limitations, if any, under Rule 701 under the Securities Act and the General Instructions
to Form S-8 Registration Statement under the Securities Act.

 

7.           Standard
Forms of Agreements.

 

7.1           Option
Agreement. Unless otherwise provided by the Board at the time the Option is granted, an Option shall comply with and
be subject to the terms and conditions set forth in the form of Option Agreement approved by the Board concurrently with its adoption
of the Plan and as amended from time to time.

 

7.2           Authority
to Vary Terms. The Board shall have the authority from time to time to vary the terms of any standard form of agreement
described in this Section 8 either in connection with the grant or amendment of an individual Award or in connection with
the authorization of a new standard form or forms; provided, however, that any such new, revised or amended standard form or forms
of agreement shall be subject to the terms of the Plan as set forth herein.

 

8.           Change
in Control.

 

8.1           Termination
of Award to Extent Not Assumed in Corporate Transaction. Effective upon the consummation of a Corporate Transaction, all outstanding
Awards under the Plan shall terminate. However, all such Awards shall not terminate to the extent they are Assumed in connection
with the Corporate Transaction.

 

8.2           Acceleration
of Award Upon Corporate Transaction. Except as provided otherwise in an individual Award Agreement, in the event of a Corporate
Transaction and:

 

    	14

    	 

    

  

(a)          for
the portion of each Award that is Assumed or Replaced, then such Award (if Assumed), the replacement Award (if Replaced), or the
cash incentive program (if Replaced) automatically shall become fully vested, exercisable and payable and be released from any
repurchase or forfeiture rights (other than repurchase rights exercisable at Fair Market Value) for all of the shares of Stock
at the time represented by such Assumed or Replaced portion of the Award immediately upon termination of the Participant's Service,
if such Service is terminated by the successor company or the Company without Cause or voluntarily by the Participant with Good
Reason within twelve (12) months after the Corporate Transaction; and

 

(b)          for
the portion of each Award that is neither Assumed nor Replaced, such portion of the Award shall automatically become fully vested
and exercisable and be released from any repurchase or forfeiture rights (other than repurchase rights exercisable at Fair Market
Value) for all of the shares of Stock at the time represented by such portion of the Award, immediately prior to the specified
effective date of such Corporate Transaction, provided however that such accelerated portion of the Award shall terminate
under Section 9.1 to the extent not exercised prior to the consummation of such Corporate Transaction.

 

8.3           Federal
Excise Tax Under Section 4999 of the Code.

 

(a)          Excess
Parachute Payment. In the event that any acceleration of vesting pursuant to an Award and any other payment or benefit
received or to be received by a Participant would subject the Participant to any excise tax pursuant to Section 4999 of the Code
due to the characterization of such acceleration of vesting, payment or benefit as an "excess parachute payment" under
Section 280G of the Code, the Participant may to the extent permitted by applicable law elect, in his or her sole discretion, to
reduce the amount of any acceleration of vesting called for under the Award in order to avoid such characterization.

 

(b)          Determination
by Independent Accountants. To aid the Participant in making any election called for under Section 8.3(a), no later
than the date of the occurrence of any event that might reasonably be anticipated to result in an "excess parachute payment"
to the Participant as described in Section 8.3(a), the Company shall request a determination in writing by independent public
accountants selected by the Company (the "Accountants"). As soon as practicable thereafter, the Accountants
shall determine and report to the Company and the Participant the amount of such acceleration of vesting, payments and benefits
that would produce the greatest after-tax benefit to the Participant. For the purposes of such determination, the Accountants may
rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and
the Participant shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order
to make their required determination. The Company shall bear all fees and expenses the Accountants may reasonably charge in connection
with their services contemplated by this Section 8.3(b).

 

    	15

    	 

    

  

9.           Tax
Withholding.

 

9.1           Tax
Withholding in General. The Company shall have the right to deduct from any and all payments made under the Plan, or to require
the Participant, through payroll withholding, cash payment or otherwise, including by means of a Cashless Exercise of an Option,
to make adequate provision for, the federal, state, local and foreign taxes, if any, required by law to be withheld by the Participating
Company Group with respect to an Award or the shares acquired pursuant thereto. The Company shall have no obligation to deliver
shares of Stock or to release shares of Stock from an escrow established pursuant to an Option Agreement or Stock Purchase Agreement
until the Participating Company Group's tax withholding obligations have been satisfied by the Participant.

 

9.2           Withholding
in Shares. The Company shall have the right, but not the obligation, to deduct from the shares of Stock issuable to a Participant
upon the exercise of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair
Market Value, as determined by the Company, equal to all or any part of the tax withholding obligations of the Participating Company
Group. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall
not exceed the amount determined by the applicable minimum statutory withholding rates.

 

10.         Compliance
with Securities Law.

 

The grant of Awards and the issuance of shares
of Stock upon exercise of Awards shall be subject to compliance with all applicable requirements of federal, state and foreign
securities laws. Awards may not be exercised if the issuance of shares of Stock upon exercise would constitute a violation of any
applicable federal, state or foreign securities laws or other laws or regulations or the requirements of any stock exchange or
market system upon which the Stock may then be listed. In addition, no Award may be exercised unless (a) a registration statement
under the Securities Act shall at the time of exercise be in effect with respect to the shares of Stock issuable upon such exercise
or (b) in the opinion of legal counsel to the Company, the shares issuable upon exercise may be issued in accordance with
the terms of an applicable exemption from the registration requirements of the Securities Act. The inability of the Company to
obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company's legal counsel to be necessary
to lawfully issue and sell any shares of Stock hereunder shall relieve the Company of any liability in respect of the failure to
issue or sell such shares. As a condition to the exercise of any Award, the Company may require the Participant to satisfy any
qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and to make any
representation or warranty with respect thereto as may be requested by the Company.

 

11.         Termination
or Amendment of Plan.

 

The Board may terminate or amend the Plan
at any time. However, subject to changes in applicable law, regulations or rules that would permit otherwise, without the approval
of the Company's stockholders, there shall be (a) no increase in the maximum aggregate number of shares of Stock that may
be issued under the Plan (except by operation of the provisions of Section 4.2), (b) no change in the class of persons
eligible to receive Incentive Stock Options, and (c) no other amendment of the Plan that would require approval of the Company's
stockholders under any applicable law, regulation or rule. No termination or amendment of the Plan shall affect any then outstanding
Award unless expressly provided by the Board. In any event, no termination or amendment of the Plan may adversely affect any then
outstanding Award without the consent of the Participant, unless such termination or amendment is required to enable an Option
designated as an Incentive Stock Option to qualify as an Incentive Stock Option or is necessary to comply with any applicable law,
regulation or rule.

 

    	16

    	 

    

  

12.         Miscellaneous
Provisions.

 

12.1         Repurchase
Rights. Shares issued under the Plan may be subject to a right of first refusal, one or more repurchase options, or
other conditions and restrictions as determined by the Board in its discretion at the time the Award is granted. The Company shall
have the right to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or
more persons as may be selected by the Company. Upon request by the Company, each Participant shall execute any agreement evidencing
such transfer restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and
all certificates representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends
evidencing any such transfer restrictions.

 

12.2         Approval
of Plan by Shareholders. The Plan may be submitted for the approval of the Company's shareholders within twelve (12) months
of the date of the Board's initial adoption of the Plan. Awards requiring shareholder approval may be granted or awarded prior
to such shareholder approval, provided that such Awards shall not be exercisable, shall not vest and the restrictions thereon shall
not lapse and no shares of Stock shall be issued pursuant thereto prior to the time when the Plan is approved by the shareholders,
and provided further that if such approval has not been obtained at the end of said twelve (12) month period, all Awards that require
shareholder approval and were previously granted or awarded under the Plan shall thereupon be canceled and become null and void.

 

12.3         No
Shareholder Rights. Except as otherwise provided herein, a Participant shall have none of the rights of a shareholder with
respect to shares of Stock covered by any Award until the Participant becomes the record owner of such shares of Stock.

 

12.4         Effect
of Plans on Other Compensation Plans. The adoption of the Plan shall not affect any other compensation or incentive plans in
effect for any Participating Company. Nothing in the Plan shall be construed to limit the right of any Participating Company: (a)
to establish any other forms of incentives or compensation for Employees, Directors or Consultants of any Participating Company,
or (b) to grant or assume options or other rights or awards otherwise than under the Plan in connection with any proper corporate
purpose including without limitation, the grant or assumption of options in connection with the acquisition by purchase, lease,
merger, consolidation or otherwise, of the business, stock or assets of any corporation, partnership, limited liability company,
firm or association.

 

12.5         Governing
Law. The Plan and any agreements hereunder shall be administered, interpreted and enforced under the internal laws of the State
of Minnesota without regard to conflicts of laws thereof.

 

    	17

    	 

    

  

12.6         Section
409A. To the extent that the Board determines that any Award granted under the Plan is subject to Section 409A of the Code,
the Award Agreement evidencing such Option shall incorporate the terms and conditions required by Section 409A of the Code. To
the extent applicable, the Plan and Award Agreements shall be interpreted in accordance with Section 409A of the Code and Department
of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or
other guidance that may be issued after the Effective Date. Notwithstanding any provision of the Plan to the contrary, in the event
that following the Effective Date the Board determines that any Award may be subject to Section 409A of the Code and related Department
of Treasury guidance (including such Department of Treasury guidance as may be issued after the Effective Date), the Board may
adopt such amendments to the Plan and the applicable Award Agreement or adopt other policies and procedures (including amendments,
policies and procedures with retroactive effect), or take any other actions, that the Board determines are necessary or appropriate
to (a) exempt the Award from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with
respect to the Award, or (b) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance
and thereby avoid the application of any penalty taxes under such Section.

 

12.7         No
Rights to Options. No Employee, Consultant or other person shall have any claim to be granted any Option pursuant to the Plan,
and neither the Company nor the Board is obligated to treat Employees, Consultants, Participants or any other persons uniformly.

 

12.8         Relationship
to Other Benefits. No payment pursuant to the Plan shall be taken into account in determining any benefits under any pension,
retirement, savings, profit sharing, group insurance, welfare or other benefit plan of any Participating Company except to the
extent otherwise expressly provided in writing in such other plan or an agreement thereunder.

 

12.9         Expenses.
The expenses of administering the Plan shall be borne by the Participating Companies.

 

IN WITNESS WHEREOF, the undersigned
Secretary of the Company certifies that the foregoing sets forth the IsoRay, Inc. 2014 Employee Stock Option Plan as duly adopted
by the Board on January 16, 2014.
