ISORAY,
INC.

STOCK
OPTION AGREEMENT

 

IsoRay, Inc. has granted
to the individual (the “Participant”) named in the Notice of Grant of Stock Option (the
“Notice”) to which this Stock Option Agreement (the “Option Agreement”)
is attached an option (the “Option”) to purchase certain shares of Common Stock upon the terms
and conditions set forth in the Notice and this Option Agreement. The Option has been granted pursuant to and shall in all respects
be subject to the terms and conditions of the IsoRay, Inc. 2017 Equity Incentive Plan (the “Plan”),
as amended to the Date of Option Grant, the provisions of which are incorporated herein by reference. By signing the Notice, the
Participant: (a) represents that the Participant has received copies of, and has read and is familiar with the terms and conditions
of, the Notice, the Plan, and this Option Agreement, (b) accepts the Option subject to all of the terms and conditions of the Notice,
the Plan, and this Option Agreement, and (c) agrees to accept as binding, conclusive, and final all decisions or interpretations
of the Board (or the Committee, if a Committee has been appointed) upon any questions arising under the Notice, the Plan, or this
Option Agreement.

 

1.            Definitions
and Construction.

 

1.1 Definitions.
Unless otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Notice or the
Plan.

 

1.2 Construction.
Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision
of this Option Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural
shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires
otherwise.

 

2.            Tax
Consequences.

 

2.1 Tax
Status of Option. This Option is intended to have the tax status designated in the Notice.

 

(a)          Incentive
Stock Option. If the Notice so designates, this Option is intended to be an Incentive Stock Option within the meaning of
Section 422(b) of the Code, but the Company does not represent or warrant that this Option qualifies as such. The Participant should
consult with the Participant’s own tax advisor regarding
the tax effects of this Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of
the Code, including, but not limited to, holding period requirements. (NOTE TO PARTICIPANT: If the Option is exercised more than
three (3) months after the date on which you cease to be an Employee (other than by reason of your death or permanent and total
disability as defined in Section 22(e)(3) of the Code), the Option will be treated as a Nonstatutory Stock Option and not as an
Incentive Stock Option to the extent required by Section 422 of the Code.)

 

    	 	1	 

     

    

 

(b)          Nonstatutory
Stock Option. If the Notice so designates, this Option is intended to be a Nonstatutory Stock Option and shall not be treated
as an Incentive Stock Option within the meaning of Section 422(b) of the Code.

 

2.2 ISO
Fair Market Value Limitation. If the Notice designates this Option as an Incentive Stock Option, then to the extent
that the Option (together with all Incentive Stock Options granted to the Participant under all stock option plans of the Participating
Company Group, including the Plan) becomes exercisable for the first time during any calendar year for shares having a Fair Market
Value greater than One Hundred Thousand Dollars ($100,000), the portion of such options which exceeds such amount will be treated
as Nonstatutory Stock Options. For purposes of this Section 2.2, options designated as Incentive Stock Options are taken into
account in the order in which they were granted, and the Fair Market Value of stock is 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 2.2,
such different limitation shall be deemed incorporated herein effective as of the date required or permitted by such amendment
to the Code. If the 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 2.2, 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.
(NOTE TO PARTICIPANT: If the aggregate Exercise Price of the Option (that is, the Exercise Price multiplied by the Number of Option
Shares) plus the aggregate exercise price of any other Incentive Stock Options you hold (whether granted pursuant to the Plan or
any other stock option plan of the Participating Company Group) is greater than $100,000, you should contact the Chief Financial
Officer of the Company to ascertain whether the entire Option qualifies as an Incentive Stock Option.)

 

3.            Administration
of Agreement.

 

All questions of interpretation
concerning this Option Agreement shall be determined by the Board. All determinations by the Board shall be final and binding upon
all persons having an interest in the Option. Any Officer shall the authority to act on behalf of the Company with respect to any
matter, right, obligation, or election which is the responsibility of or which is allocated to the Company herein, provided the
Officer has apparent authority with respect to such matter, right, obligation, or election.

 

4.            Exercise
of the Option.

 

4.1 Right
to Exercise.

 

(a)          In
General. Except as otherwise provided herein, the Option shall be exercisable on and after the Initial Exercise Date set
forth and prior to the termination of the Option (as provided in Section 6) in an amount not to exceed the Number of Option Shares
less the number of shares previously acquired upon exercise of the Option. In no event shall the Option be exercisable for more
shares than the Number of Option Shares, as adjusted pursuant to Section 9.

 

    	 	2	 

     

    

 

(b)          ISO
Exercise Limitation. If this Option is designated as an Incentive Stock Option in the Notice, then notwithstanding
the provisions of Section 4.1(a) and except as provided in Section 4.1(c), the aggregate Fair Market Value of the shares of
Stock with respect to which the Participant may exercise the Option for the first time during any calendar year, when added to
the aggregate Fair Market Value of shares subject to other options designated as Incentive Stock Options and granted to the Participant
under other stock option plans of the Participating Company Group prior to the Date of Option Grant which options are exercisable
for the first time during the same calendar year, shall not exceed One Hundred Thousand Dollars ($100,000). For purposes of the
preceding sentence, 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 shares of stock shall be determined as of the time the option with respect to such shares is granted.
Such limitation on exercise shall be referred to in this Option Agreement as the “ISO Exercise Limitation.”
If Section 422 of the Code is amended to provide for a different limitation from that set forth in this Section 4.1(b),
the ISO Exercise Limitation shall be deemed amended effective as of the date required or permitted by such amendment to the Code.
The ISO Exercise Limitation shall terminate upon the earlier of (i) the Participant’s termination of Service, (ii) the
day immediately prior to the effective date of a Corporate Transaction in which the Option is not Assumed or Replaced as provided
in Section 8, or (iii) the day ten (10) days prior to the Option Expiration Date. Upon such termination of the ISO Exercise
Limitation, the Option shall be deemed a Nonstatutory Stock Option to the extent of the number of shares subject to the Option
that would otherwise exceed the ISO Exercise Limitation.

 

(c)          Exception
to ISO Exercise Limitation. Notwithstanding any other provision of this Option Agreement, if compliance with the ISO Exercise
Limitation as set forth in Section 4.1(b) will result in the exercisability of any Vested Shares being delayed more than thirty
(30) days beyond the date such shares become Vested Shares (the “Vesting Date”), the Option shall
be deemed to be two (2) options. The first option shall be for the maximum portion of the Number of Option Shares that can comply
with the ISO Exercise Limitation without causing the Option to be unexercisable in the aggregate as to Vested Shares on the Vesting
Date for such shares. The second option, which shall not be treated as an Incentive Stock Option as described in section 422(b)
of the Code, shall be for the balance of the Number of Option Shares; that is, those such shares which, on the respective Vesting
Date for such shares, would be unexercisable if included in the first option and thereby made subject to the ISO Exercise Limitation.
Shares treated as subject to the second option shall be exercisable on the same terms and at the same time as set forth in this
Option Agreement; provided, however, that (i) Section 4.1(b) shall not apply to the second option and (ii) each such
share shall become a Vested Share on the Vesting Date such share must first be allocated to the second option pursuant to the preceding
sentence. Unless the Participant specifically elects to the contrary in the Participant’s written notice of exercise, the
first option shall be deemed to be exercised first to the maximum possible extent and then the second option shall be deemed to
be exercised.

 

    	 	3	 

     

    

 

4.2 Method
of Exercise. Exercise of the Option shall be by written notice to the Company, which must state the election to exercise
the Option, the number of whole shares of Stock for which the Option is being exercised and such other representations and agreements
as to the Participant’s investment intent with respect to such shares as may be required pursuant to the provisions of this
Option Agreement. The written notice must be signed by the Participant and must be delivered in person, by certified or registered
mail, return receipt requested, by confirmed facsimile transmission, or by such other means as the Board may permit, to the Chief
Financial Officer of the Company, or other authorized representative of the Participating Company Group, prior to the termination
of the Option as set forth in Section 6, accompanied by full payment of the aggregate Exercise Price for the number of shares of
Stock being purchased. The Option shall be deemed to be exercised upon receipt by the Company of such written notice, the aggregate
Exercise Price, and, if required by the Company, such executed agreement.

 

4.3 Payment
of Exercise Price.

 

(a)          Forms
of Consideration Authorized. Except as otherwise provided below, payment of the aggregate Exercise Price for the number
of shares of Stock for which the Option is being exercised shall be made (i) in cash, by check, or cash equivalent, (ii) by
tender to the Company, or attestation to the ownership, of whole shares of Stock owned by the Participant having a Fair Market
Value not less than the aggregate Exercise Price, (iii) by means of a Cashless Exercise, as defined in Section 4.3(b), or (iv)
by any combination of the foregoing.

 

(b)          Limitations
on Forms of Consideration.

 

(i)          Tender
of Stock. Notwithstanding the foregoing, the 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. The 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 not used for another option exercise by attestation during such period) or were not acquired, directly or indirectly,
from the Company.

 

(ii)         Cashless
Exercise. A “Cashless Exercise” means the delivery of a properly executed notice together
with irrevocable instructions to a broker in a form acceptable to the Company providing for the assignment to the Company of the
proceeds of a sale or loan with respect to some or all of the shares of Stock acquired upon the exercise of the Option pursuant
to a program or procedure approved by the Company (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). The Company reserves,
at any and all times, the right, in the Company’s sole and absolute discretion, to decline to approve or terminate any such
program or procedure.

 

    	 	4	 

     

    

 

4.4 Tax
Withholding. At the time the Option is exercised, in whole or in part, or at any time thereafter as requested by the
Company, the Participant hereby authorizes withholding from payroll and any other amounts payable to the Participant, and otherwise
agrees to make adequate provision for (including by means of a Cashless Exercise to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding obligations of the Participating Company Group, if any,
which arise in connection with the Option, including, without limitation, obligations arising upon (i) the exercise, in whole
or in part, of the Option, (ii) the transfer, in whole or in part, of any shares acquired upon exercise of the Option, (iii) the
operation of any law or regulation providing for the imputation of interest, or (iv) the lapsing of any restriction with respect
to any shares acquired upon exercise of the Option. The Option is not exercisable unless the tax withholding obligations of the
Participating Company Group are satisfied. Accordingly, the Company shall have no obligation to deliver shares of Stock until the
tax withholding obligations of the Participating Company Group have been satisfied by the Participant.

 

4.5 Certificate
Registration. Except in the event the Exercise Price is paid by means of a Cashless Exercise, the certificate for the
shares as to which the Option is exercised shall be registered in the name of the Participant, or, if applicable, in the names
of the heirs of the Participant.

 

4.6 Restrictions
on Grant of the Option and Issuance of Shares. The grant of the Option and the issuance of shares of Stock upon exercise
of the Option shall be subject to compliance with all applicable requirements of federal, state or foreign securities laws. The
Option 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 any other laws or regulations, or the requirements of any stock exchange or market system
upon which the Stock may then be listed. In addition, the Option may not be exercised unless (i) a registration statement
under the Securities Act shall at the time of exercise be in effect with respect to the shares issuable upon exercise or (ii) 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 PARTICIPANT IS CAUTIONED THAT THE OPTION MAY
NOT BE EXERCISED UNLESS THE FOREGOING CONDITIONS ARE SATISFIED. ACCORDINGLY, THE PARTICIPANT MAY NOT BE ABLE TO EXERCISE THE OPTION
WHEN DESIRED EVEN THOUGH THE OPTION IS VESTED. 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 subject to the Option 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 the Option, 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.

 

4.7 No
Fractional Shares. The Participant acknowledges and agrees that the Company will not issue fractional shares upon the
exercise of the Option, and the number of Shares in the event of such an exercise shall be rounded down to the nearest whole number.

 

5.            Nontransferability
of the Option.

 

The Option may be exercised
during the lifetime of the Participant only by the Participant or the Participant’s
guardian or legal representative and may not be assigned or transferred in any manner except by will or by the laws of descent
and distribution. Following the death of the Participant, the Option, to the extent provided in Section 7, may be exercised by
the Participant’s legal representative or by any person empowered
to do so under the deceased Participant’s will or under the
then applicable laws of descent and distribution.

 

    	 	5	 

     

    

 

6.            Termination
of the Option.

 

The Option shall terminate
and may no longer be exercised after the first to occur of (a) the Option Expiration Date, (b) the last date for exercising
the Option following termination of the Participant’s Service
as described in Section 7, or (c) a Corporate Transaction to the extent provided in Section 8.

 

7.            Effect
of Termination of Service.

 

If the Participant’s
Service terminates for any reason, including but not limited to 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 (or the Participant’s
guardian, 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 Option Expiration Date. Unless otherwise defined in a contract of employment or service between
the Participant and a Participating Company, for purposes of this Option Agreement, “Cause” shall
have the meaning given such term in the Plan.

 

8.            Corporate
transaction.

 

8.1 Termination
of Option to Extent Not Assumed in Corporate Transaction. Effective upon the consummation of a Corporate Transaction, the Option
shall terminate. However, the Option shall not terminate to the extent it is Assumed in connection with the Corporate Transaction.

 

8.2 Acceleration
of Award Upon Corporate Transaction. In the event of a Corporate Transaction and:

 

(a)          for
the portion of the Option that is Assumed or Replaced, then the Option (if Assumed), the replacement Option (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 Option 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 the Option that is neither Assumed nor Replaced, such portion of the Option 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 Option, immediately prior to the specified
effective date of such Corporate Transaction, provided however that such accelerated portion of the Option shall terminate
under Section 8.1 to the extent not exercised prior to the consummation of such Corporate Transaction.

 

    	 	6	 

     

    

 

9.            Adjustments
for Changes in Capital Structure.

 

Subject to any required
action by the stockholders of the Company, in the event of any change in the Stock effected without receipt of consideration by
the Company, whether through merger, consolidation, reorganization, reincorporation, recapitalization, reclassification, stock
dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination of shares, exchange of shares, or similar
change in the capital structure of the Company, or in the event of payment of a dividend or distribution to the stockholders of
the Company in a form other than Stock (excepting normal cash dividends) that has a material effect on the Fair Market Value of
shares of Stock, appropriate and proportionate adjustments shall be made in the number, Exercise Price and class of shares subject
to the Option, in order to prevent dilution or enlargement of the Participant’s rights under the Option. 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 9 shall
be rounded down to the nearest whole number, and in no event may the Exercise Price of the 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.

 

10.          Rights
as a Stockholder, Employee, or Consultant.

 

The Participant shall
have no rights as a stockholder with respect to any shares covered by the Option until the date of the issuance of a certificate
for the shares for which the Option has been exercised (as evidenced by the appropriate entry on the books of the Company or of
a duly authorized transfer agent of the Company). No adjustment shall be made for dividends, distributions, or other rights for
which the record date is prior to the date such certificate is issued, except as provided in Section 9. If the Participant is an
Employee, the Participant understands and acknowledges that, except as otherwise provided in a separate, written employment agreement
between a Participating Company and the Participant, the Participant’s
employment is “at will” and is for no specified term. Nothing in this Option Agreement shall confer upon the Participant
any right to continue in the Service of a Participating Company or interfere in any way with any right of the Participating Company
Group to terminate the Participant’s Service as an Employee
or Consultant, as the case may be, at any time. Nothing in this Option shall confer on any person any legal or equitable right
against the Company, directly or indirectly, or give rise to any cause of action at law or in equity against any Participating
Company. The Option granted hereunder shall not form any part of the wages or salary of Participant for purposes of severance pay
or termination indemnities, irrespective of the reason for termination of employment. Under no circumstances shall any person ceasing
to be an employee of any Participating Company be entitled to any compensation for any loss of any right or benefit under this
Option or the Plan which such employee might otherwise have enjoyed but for termination of employment, whether such compensation
is claimed by way of damages for wrongful or unfair dismissal, breach of contract or otherwise.

 

    	 	7	 

     

    

 

11.          Notice
of Sales Upon Disqualifying Disposition.

 

The Participant shall
dispose of the shares acquired pursuant to the Option only in accordance with the provisions of this Option Agreement. In addition,
if the Notice designates this Option as an Incentive Stock Option, the Participant shall (a) promptly notify the Chief Financial
Officer of the Company if the Participant disposes of any of the shares acquired pursuant to the Option within one (1) year after
the date the Participant exercises all or part of the Option or within two (2) years after the Date of Option Grant and (b) provide
the Company with a description of the circumstances of such disposition. Until such time as the Participant disposes of such shares
in a manner consistent with the provisions of this Option Agreement, unless otherwise expressly authorized by the Company, the
Participant shall hold all shares acquired pursuant to the Option in the Participant’s
name (and not in the name of any nominee) for the one-year period immediately after the exercise of the Option and the two-year
period immediately after Date of Option Grant. At any time during the one-year or two-year periods set forth above, the Company
may place a legend on any certificate representing shares acquired pursuant to the Option requesting the transfer agent for the
Company’s stock to notify the Company of any such transfers.
The obligation of the Participant to notify the Company of any such transfer shall continue notwithstanding that a legend has been
placed on the certificate pursuant to the preceding sentence.

 

12.          Legends.

 

The Company may at
any time place legends referencing any applicable federal, state or foreign securities law restrictions on all certificates representing
shares of Stock subject to the provisions of this Option Agreement. The Participant shall, at the request of the Company, promptly
present to the Company any and all certificates representing shares acquired pursuant to the Option in the possession of the Participant
in order to carry out the provisions of this Section. Unless otherwise specified by the Company, legends placed on such certificates
shall include, but shall not be limited to, the following:

 

12.1         “THE
SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES,
THE SALE IS MADE IN ACCORDANCE WITH RULE 144 OR RULE 701 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY
SATISFACTORY TO THE COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.”

 

    	 	8	 

     

    

 

12.2         “THE
SHARES EVIDENCED BY THIS CERTIFICATE WERE ISSUED BY THE CORPORATION TO THE REGISTERED HOLDER UPON EXERCISE OF AN INCENTIVE STOCK
OPTION AS DEFINED IN SECTION 422 OF THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (“ISO”). IN ORDER TO
OBTAIN THE PREFERENTIAL TAX TREATMENT AFFORDED TO ISOs, THE SHARES SHOULD NOT BE TRANSFERRED PRIOR TO [INSERT DISQUALIFYING
DISPOSITION DATE HERE]. SHOULD THE REGISTERED HOLDER ELECT TO TRANSFER ANY OF THE SHARES PRIOR TO THIS DATE AND FOREGO ISO
TAX TREATMENT, THE TRANSFER AGENT FOR THE SHARES SHALL NOTIFY THE CORPORATION IMMEDIATELY. THE REGISTERED HOLDER SHALL HOLD ALL
SHARES PURCHASED UNDER THE INCENTIVE STOCK OPTION IN THE REGISTERED HOLDER’S
NAME (AND NOT IN THE NAME OF ANY NOMINEE) PRIOR TO THIS DATE OR UNTIL TRANSFERRED AS DESCRIBED ABOVE.”

 

13.          Restrictions
on Transfer of Shares.

 

No shares of Stock
acquired upon exercise of the Option may be sold, exchanged, transferred (including, without limitation, any transfer to a nominee
or agent of the Participant), assigned, pledged, hypothecated or otherwise disposed of, including by operation of law, in any manner
which violates any of the provisions of this Option Agreement and any such attempted disposition shall be void. The Company shall
not be required (a) to transfer on its books any shares that have been transferred in violation of any of the provisions set
forth in this Option Agreement or (b) to treat as owner of such shares, accord the right to vote as such owner or pay dividends
to any transferee to whom such shares have been so transferred.

 

14.          Miscellaneous
Provisions.

 

14.1         Binding
Effect. Subject to the restrictions on transfer set forth herein, this Option Agreement shall inure to the benefit of and be
binding upon the parties hereto and their respective heirs, executors, administrators, successors and assigns.

 

14.2         Termination
or Amendment. The Board may terminate or amend the Plan or the Option at any time; provided, however, that except as provided
in Section 8.1 in connection with a Corporate Transaction, no such termination or amendment may adversely affect the Option or
any unexercised portion hereof without the consent of the Participant, unless such termination or amendment is necessary to comply
with any applicable law or government regulation or is required to enable the Option, if designated an Incentive Stock Option in
the Notice, to qualify as an Incentive Stock Option. No amendment or addition to this Option Agreement shall be effective unless
in writing.

 

14.3         Notices.
Any notice required or permitted hereunder shall be given in writing and shall be deemed effectively given (except to the extent
that this Option Agreement provides for effectiveness only upon actual receipt of such notice) upon personal delivery or upon deposit
in the United States Post Office, by registered or certified mail, with postage and fees prepaid, addressed to the other party
at the address shown below that party’s signature or at such
other address as such party may designate in writing from time to time to the other party.

 

14.4         Employment
Agreement. The terms and provisions of the employment agreement, if any, between Participant and any Participating Company
(the “Employment Agreement”) that relate to or affect this Option are incorporated herein by reference.
Notwithstanding the provisions of this Option, in the event of any conflict or inconsistency between the terms and conditions of
this Option and the terms and conditions of the Employment Agreement, the terms and conditions of the Employment Agreement shall
be controlling.

 

    	 	9	 

     

    

 

14.5         Integrated
Agreement. The Notice, this Option Agreement, and the Plan, together with any employment, service, or other agreement with
the Participant and a Participating Company referring to the Option, will constitute the entire understanding and agreement of
the Participant and the Participating Company Group with respect to the subject matter contained herein or therein and supersedes
any prior agreements, understandings, restrictions, representations, or warranties among the Participant and the Participating
Company Group with respect to such subject matter other than those as set forth or provided for herein or therein. To the extent
contemplated herein or therein, the provisions of the Notice and the Option Agreement shall survive any exercise of the Option
and shall remain in full force and effect.

 

14.6         Applicable
Law. This Option Agreement shall be governed by the laws of the State of Minnesota as such laws are applied to agreements between
Minnesota residents entered into and to be performed entirely within the State of Minnesota.

 

14.7         Counterparts.
The Notice may be executed in counterparts, each of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

14.8         Consultation
with Professional Tax and Investment Advisors. The holder of this Option acknowledges that the grant, exercise, vesting or
any payment with respect to this Option, and the sale or other taxable disposition of the shares of Stock acquired pursuant to
the exercise thereof, may have tax consequences pursuant to the Code or under local, state or international tax laws. The holder
further acknowledges that such holder is relying solely and exclusively on the holder's own professional tax and investment advisors
with respect to any and all such matters (and is not relying, in any manner, on any Participating Company or any of its employees
or representatives). Finally, the holder understands and agrees that any and all tax consequences resulting from the Option and
its grant, exercise, vesting or any payment with respect thereto, and the sale or other taxable disposition of the shares of Stock
acquired pursuant to the Plan, is solely and exclusively the responsibility of the holder without any expectation or understanding
that any Participating Company or any of its employees or representatives will pay or reimburse such holder for such taxes or other
items.

 

14.9         Employment
Agreement. If Participant has an employment agreement with the Company that contains terms that are in conflict with this Option
Agreement (including, or clarity, Section 8 hereof), then the terms of the employment will control.

of Option. I hereby elect to exercise the Option to purchase the following number of Shares, all of which are Vested Shares,
in accordance with the Notice and the Option Agreement:

	Shares Purchased:

Exhibit 10.1

SECOND AMENDED AND RESTATED
EXPENSE SUPPORT AND CONDITIONAL

REIMBURSEMENT AGREEMENT

This Second Amended and Restated
Expense Support and Conditional Reimbursement Agreement (this “Agreement”) is made as of June 29, 2017 by and among
Corporate Capital Trust II, a Delaware statutory trust (the “Company”), CNL Fund Advisors II, LLC, a Delaware limited
liability Company (the “Advisor”) and KKR Credit Advisors (US) LLC, a Delaware limited liability company (the “Sub-Advisor”).
The Advisor and Sub-Advisor are collectively referred to as the “Advisors.”

WHEREAS, the
Company maintains on file with the U.S. Securities and Exchange Commission a registration statement on Form N-2 (File Nos. 333-199018
and 814-01108) covering the continuous offering and sale of the Company’s common stock pursuant to the Securities Act of
1933 (the “Registration Statement”);

WHEREAS, the
Company and the Advisor have entered into an Investment Advisory Agreement dated as of September 24, 2015 (the “Advisory
Agreement”), and the Advisor, the Sub-Advisor and the Company have entered into an Investment Sub-Advisory Agreement dated
as of September 24, 2015 (the “Sub-Advisory Agreement”, and together with the Advisory Agreement, the “Advisory
Agreements”); and

WHEREAS, the
Company, the Advisor, and the Sub-Advisor have entered into an Expense Support and Conditional Reimbursement Agreement, dated as
of September 24, 2015 (as amended from time to time, the “Original Expense Support Agreement”), and

WHEREAS, the
Company and the Advisors have determined that it is appropriate and in the best interest of the Company amend and restate the Original
Expense Support Agreement to adjust the Expense Support Payment Period (as defined below) to reduce the Company’s operating
expenses until the Company has achieved economies of scale sufficient to ensure that it bears a reasonable level of expense in
relation to its investment income.

NOW, THEREFORE,
in consideration of the premises and the mutual agreements herein contained, and for other good and valuable consideration (the
receipt and sufficiency of which are hereby acknowledged), the parties hereto agree as follows:

1. EXPENSE SUPPORT
PAYMENTS

During the period beginning on
the date on which the Company has satisfied the “minimum offering requirement” (as such term is defined in the Company’s
Registration Statement) and ending on September 30, 2017 (the “Expense Support Payment Period”), the Advisor and the
Sub-Advisor each hereby agrees to pay the expenses of the Company on a monthly basis as follows: the lesser of, (i) the amount
equal to 50% of all Operating Expenses (as defined below) for each month during the Expense Support Payment Period in which the
Company’s board of trustees (the “Trustees”) declares a Distribution (as defined below) or (ii) the amount equal
to 50% of the positive difference between the Company’s Distributions accrued to the Company’s shareholders in each
month less monthly Available Operating Funds (as defined below) recognized by the Company on account of its investment portfolio provided,
that each Advisor hereby agrees and confirms that, it shall be jointly and severally liable to the Company for the share of Operating
Expenses payable by the other Advisor to the extent the other Advisor fails to make such payment. In the event that Available Operating
Funds are negative for a particular month the Advisor and Sub-Advisor will pay expenses as outlined in (i) above. Any payment made
by an Advisor pursuant to the preceding sentence shall be referred to herein as an “Expense Support Payment.” The Advisors’
obligation to make Expense Support Payments for any month during the Expense Support Payment Period during such month shall automatically
become a joint and several liability of the Advisors and the right to such Expense Support Payment shall be an asset of the Company
immediately upon the Trustee’s declaration of a Distribution. The Expense Support Payment for any month shall be paid by
the Advisors to the Company in any combination of cash or other immediately available funds, and/or offsets against amounts due
from the Company to the Advisors, no later than five business days after the end of such month.

For purposes of this Agreement
(a) “Distribution” means any distribution payable to shareholders of the Company at the time such distribution is declared
by the Trustees; and (b) “Operating Expenses” means all operating costs and expenses incurred by the Company, including
the Management Fees pursuant to the Advisory Agreements, taxes, all interest cost, financing fees and other financing costs related
to indebtedness for such period, but shall exclude any Incentive Fees pursuant to the Advisory Agreements and any ongoing shareholder
servicing and distribution fees, any organizational and offering expenses and Expense Support Payments and reimbursements as determined
under generally accepted accounting principles; and (c) “Available Operating Funds” means the sum of (i) the Company’s
estimated investment company taxable income (including net short-term capital gains reduced by net long-term capital losses), and
(ii) the Company’s net capital gains (including the excess of net long-term capital gains over net short-term capital losses)
excluding any Expense Support Payments and reimbursements. The Advisor and Sub-Advisor reserve the right to adjust Expense Support
Payments if estimable taxable income changes, subject to Board of Trustees approval.

    	 

    	 

    

2.
CONDITIONAL REIMBURSEMENT

The Company hereby agrees to reimburse
the Advisors in an amount, in the aggregate, equal to the aggregate Expense Support Payments, the repayment of each Expense Support
Payment to be made within a period not to exceed three years from the date in which such Expense Support Payment was made by an
Advisor.

The Company agrees to reimburse
the Advisors pro rata based on the total aggregate Expense Support Payments made by each Advisor. In the
aggregate, all Expense Support Payment made by the Advisors to the Company that have not been previously reimbursed by the Company
to the Advisors shall remain eligible for reimbursement subject to the conditions herein.

Reimbursement shall be made as
promptly as possible after the Expense Support Payment Period ends, but only to the extent such reimbursement does not cause the
Company’s Other Operating Expenses (as defined herein) to exceed the lesser of: (A) 1.75% of average net assets attributable
to common shares on an annualized basis after taking such payment into account or (B) the percentage of our average net assets
attributable to shares of our common stock represented by Other Operating Expenses during the period in which such Expense Support
Payment from the Advisors was made (provided, however, that this clause (B) shall not apply to any reimbursement payment which
relates to Expense Support Payment from the Advisors made during the same period). Additionally, reimbursement payments shall only
be made to the extent they do not exceed estimated taxable income before reimbursements. Notwithstanding anything to the contrary
in this Agreement, no reimbursement payment shall be made if the Effective Rate of Distributions Per Share on any class of stock
declared by the Company at the time of such reimbursement payment is less than the Effective Rate of Distributions Per Share on
any class of stock at the time the Expense Support Payment was made to which such reimbursement payment relates. For purposes of
the Agreement, “Effective Rate of Distributions Per Share” means actual declared distribution rate per share exclusive
of return of capital, if any. “Other Operating Expenses” shall mean all Operating Expenses, base management fees, interest
costs, financing fees and financing costs, and brokerage commissions and extraordinary expenses. The calculation of average net
assets shall be consistent with such periodic calculations of average net assets in the Company’s financial statements

3.
TERM AND TERMINATION OF AGREEMENT

3.1 TERM
OF AGREEMENT. This Agreement shall become effective immediately upon the date on which the Company has satisfied the “minimum
offering requirement” (as such term is defined in the Company’s Registration Statement). Once effective, this Agreement
shall remain in effect until December 31, 2018, unless otherwise terminated pursuant to Section 3.2. Sections 3 and 4 of this Agreement
shall survive any termination of this Agreement. Notwithstanding anything to the contrary, Section 2 of this Agreement shall survive
any termination of this Agreement with respect to any Expense Support Payments that have not been reimbursed by the Company to
the Advisors. If an Expense Support Payment has not been reimbursed prior three years from the date of such Expense Support Payment
was made, the Company’s obligation to pay such Expense Support Payment shall automatically terminate, and be of no further
effect.

3.2 TERMINATION
OF AGREEMENT. This Agreement may be terminated by the Advisors acting jointly hereto upon written notice to the Company, except
that once effective, the Advisors may not terminate their obligations under Section 1. This Agreement shall automatically terminate
in the event of (a) the termination by the Company of either the Advisory Agreement or Sub-Advisory Agreement or (b) the dissolution
or liquidation of the Company. Notwithstanding any provision to the contrary, if this Agreement terminates automatically pursuant
to clause (a) of this Section 3.2, the Company agrees to make a repayment to the Advisors in an amount equal to all Expense Support
Payments not previously reimbursed. Such repayment shall be made to the Advisors, pro rata based on the aggregate
unreimbursed Expense Support Payments made by each Advisor, not later than 30 days after such termination of this Agreement.
