including all amendments to any such Warrants and all warrants issued in exchange, transfer or replacement therefor. 
 “Warrant
Units” shall have the meaning specified in the introduction to this Warrant. 
 2. Exercise of Warrant. 
 (a) Exercise Agreement. While this Warrant remains outstanding and exercisable in accordance with subparagraph
2(a) below, the Holder may exercise, in whole or in part, the purchase rights evidenced hereby: (i) the surrender of the Warrant, together with a completed Exercise Agreement in the form attached hereto (“Exercise
Agreement”) to the Secretary of the Company at its principal offices, (ii) the payment to the Company of an amount equal to the aggregate Exercise Price, for the number of Warrant Units being purchased, in cash (in the form of
immediately available funds in U.S. Dollars); and (iii) full compliance with the other applicable provisions of this Warrant. 
 (b) Exercise Period. This Warrant is exercisable at any time from and after the date hereof (the “Exercise Period”) as follows: 20% of the Warrant Units through the one (1) year period from the date of this
Warrant and an additional 20% of the Warrant Units on each one (1) year anniversary of this Warrant. 
 (c) Issuance
of Certificates. Certificates for the Warrant Units, representing the aggregate number of Units specified in said Exercise Agreement, shall be delivered to the Holder within a reasonable time, not exceeding five (5) business days,
after the rights represented by this Warrant shall have been so exercised. The Unit certificate or certificates so delivered shall be in such denominations as may be requested by the holder hereof and shall be registered in the name of said
Holder or such other name as shall be designated by said Holder (subject to the transfer restrictions applicable to this Warrant and to Units purchased upon exercise of this Warrant). If this Warrant shall have been exercised only in part,
then, unless this Warrant has expired, the Company shall, at its expense, at the time of delivery of said Unit certificates(s), deliver to said holder a new Warrant representing the right to purchase the number of Units with respect to which this
Warrant shall not then have been exercised. The Company 

  

 2 








 
shall pay all expenses and charges payable in connection with the preparation, execution and delivery of Unit certificates (and any new Warrants) pursuant to
this paragraph 2 except that, in case such Unit certificates shall be registered in a name or names other than the Holder of this Warrant or such Holder’s nominee, funds sufficient to pay all Unit transfer taxes which shall be payable in
connection with the execution and delivery of such Unit certificates shall be paid by the Holder to the Company at the time of delivery of such Unit certificates by the Company as mentioned above. 
 (d) No Fractional Shares. This Warrant shall be exercisable only for a whole number of Warrant Units. No fractions of
Units, or scrip for any such fractions of Units, shall be issued upon the exercise of this Warrant. 
 3. Units to be Fully Paid;
Reservations of Units. The Company covenants and agrees that all Warrant Units will be duly authorized and validly issued and upon issuance in accordance with the terms and conditions hereof, will be fully paid and nonassessable and free
from all taxes, liens and charges with respect to the issue thereof. Without limiting the generality of the foregoing, the Company covenants and agrees that it will from time to time take all such action as may be required to assure that the
par value per Warrant Unit is at all times equal to or less than the Exercise Price then in effect. The Company further covenants and agrees that during the period within which the rights represented by this Warrant may be exercised, the
Company shall at all times reserve and keep available out of its authorized but unissued Units, solely for the purpose of effecting the exercise of the rights represented by this Warrant and any other Warrants, such number of its Units as shall from
time to time be sufficient to effect the exercise of all then outstanding Warrants; and if at any time the number of authorized but unissued Units shall not be sufficient to effect the exercise of all then outstanding Warrants, in addition to such
other remedies as shall be available to the Holder, the Company will take such corporate action as may, in the opinion of its counsel, be necessary to increase its authorized but unissued Units to such number of Units as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the requisite member approval of any necessary amendment to the Certificate or Articles of Organization 
 4. Anti-Dilution Provisions. The number, rights and privileges of the Units issuable upon exercise of this Warrant shall be subject to the
following adjustments: 
 a. Subdivisions, Combinations and Stock Dividends. If the Company shall at any time
prior to the expiration of this Warrant subdivide its Units, by split up or otherwise, or combine its Units, or issue additional Units as a dividend with respect to any Units, the number of Warrant Units issuable on the exercise of this Warrant
shall forthwith be proportionately increased in the case of a subdivision or Units dividend, or proportionately decreased in the case of a combination. Appropriate adjustments shall also be made to the Exercise Price payable per share, but the
aggregate Exercise Price payable for the total number of Warrant Units purchasable under this Warrant (as adjusted) shall remain the same. Any adjustment under this subparagraph 4(a) shall become effective at the close of business on the
date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of such dividend. 
  

 3 








 b. Other Distributions. In the event the Company shall declare a distribution
payable in securities of other persons, evidences of indebtedness issued by the Company or other persons, assets (excluding cash dividends) or options or rights not referred to in subsection 4(b), then, in each such case for the purpose of this
subsection 4(b), provision shall be made by the Company such that the Holder shall receive upon exercise of this Warrant a proportionate share of any such distribution s though it were the holder of the Units as of the record date fixed for the
determination of the Unit holders of the Company entitled to receive such distribution. 
 c. Reclassification,
Reorganization and Consolidation. If the Company shall effect any reclassification or similar change of the outstanding shares of the Company’s Capital Units (other than as set forth in subparagraph 4(a) or 4(b) above),
or a consolidation or merger of the Company with another corporation, this Warrant shall, after such reorganization, reclassification, consolidation, or merger, be exercisable only for the number of Capital Units or other properties, including cash,
to which a holder of the number of Units deliverable upon exercise of this Warrant would have been entitled upon such reorganization, reclassification, consolidation or merger if this Warrant had been exercised immediately prior to the effective
date of such event; and, in any such case, appropriate adjustments shall be made in the application of the provisions set forth in this Section 4 with respect to the rights and interest thereafter of the Holder in order that the
provisions set forth in this Section 4 (including provisions with respect to changes in and other adjustments of the exercise rights in this Section 4 ) shall thereafter be applicable, as nearly as equivalent as may be
practicable, to any shares of stock or other securities thereafter deliverable upon the exercise of this Warrant. 
 d.
Notice of Transaction. The Company shall give written notice to the Holder at least ten (10) business days prior to the consummation of any transaction within the scope of clause (a) through (c) of this paragraph 4 and
provide in such written notice a brief description of the terms and conditions of such transaction. 
 e. Notice of
Adjustment. When any adjustment is required to be made in the number or kind of shares purchasable upon exercise of the Warrant, or in the Exercise Price, the Company shall promptly notify the Holder of such event and of the number of
Capital Units or other securities or property thereafter purchasable upon exercise of this Warrant. 
 5. Certain Agreements of the
Company. The Company covenants and agrees that: 
 a. Certain Actions Prohibited. The Company will not,
by amendment of its Certificate or Articles of Organization 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 of
this Warrant and will take all such actions as may reasonably be requested by the Holder of any Warrant in order to protect the exercise privilege of the Holders of the Warrants against impairment. 
 b. Successors and Assigns. This Warrant will be binding upon any entity succeeding to the Company by merger or consolidation.

 c. Issuance of Warrant Securities. If the issuance of any Warrant Units
required to be reserved for purposes of exercise of this Warrant is required to be registered with or approved by any federal or state governmental authority under any federal or state law (other than any registration under the Act or state
securities laws), before such Warrant Units may be issued upon exercise of this Warrant, the Company will, at its expense, use its best efforts to cause such shares to be so registered or approved, at such time, so that such shares may be issued in
accordance with the terms hereof. 
 6. Issue Tax. The issuance of certificates for Warrant Units upon the exercise of Warrants
shall be made without charge to the Holders of such Warrants or such shares for any issuance tax in respect thereof, provided that the Company shall not be required to pay any tax which may be payable in respect of any transfer involved in
the issuance and delivery of any certificate in a name other than that of the Holder of the Warrant exercised. 
 7. Closing of
Books. Subject to paragraph 9, the Company will at no time close its transfer books against the transfer of any Warrant, of any Warrant Units issued or issuable upon the exercise of any Warrant, or in any manner interfere with the timely
exercise of this Warrant. 
 8. No Rights or Liabilities as a Holder of Units. This Warrant shall not entitle the Holder to any
voting rights or other rights as a holder of Units of the Company. No provision of this Warrant, in the absence of affirmative action by the Holder to purchase Warrant Units, and no mere enumeration herein of the rights or privileges of the
Holder, shall give rise to any liability of such Holder for the Exercise Price or as a holder of Units of the Company, whether such liability is asserted by the Company or by creditors of the Company. 
 9. Transfer and Exchange. 
 a. Transfers. This Warrant may not be transferred or assigned in whole or in part without compliance with all applicable federal and state securities laws and the Operating Agreement, by the Holder or the transferee (including
the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, if such are requested by the Company). Subject to the terms of this Warrant with respect to compliance with applicable securities laws
and the Operating Agreement, this Warrant may be transferred, in whole or in part, to any person or business entity, by presentation of the Warrant to the Company with written instructions for such transfer. Upon such presentation for transfer,
the Company shall promptly execute and deliver a new Warrant or Warrants in the form hereof in the name of the assignee or assignees and in the denominations specified in such instructions. 
 b. Warrant Exchangeable for Different Denominations. This Warrant is exchangeable, upon the surrender hereof by the Holder at
the principal office of the Company (or such other office or agency of the Company as it may designate by notice in writing to the Holder), for new Warrants of like tenor representing in the aggregate the right to subscribe for and purchase the
number of Units which may be subscribed for and purchased hereunder, each of such new Warrants to represent the right to subscribe for and purchase such number of shares as shall be designated by said Holder at the time of such surrender.

 c. Replacement of Warrant. Upon receipt of written notice from a Holder or other evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant or any stock certificate for the Warrant Units and, in the case of any 

  

 5 








 
such loss, theft or destruction, upon receipt of indemnity reasonably satisfactory to the Company, or in the case of any such mutilation upon surrender and
cancellation of such Warrant or Unit certificate, the Company will make and deliver a new Warrant or Unit certificate in lieu of the lost, stolen, destroyed or mutilated Warrant or Unit certificate. 
 d. Cancellation; Payment of Expenses. Upon the surrender of this Warrant in connection with any exchange, transfer or
replacement as provided in this paragraph 9, this Warrant shall be promptly canceled by the Company. The Company shall pay all taxes (other than securities transfer taxes) and all other expenses and charges payable in connection with the
preparation, execution and delivery of Warrants pursuant to this paragraph 9 
 e. Compliance With Securities
Laws. 
 (i) The Holder of this Warrant represents and warrants that this Warrant and the Warrant Units to be issued upon
exercise hereof are being acquired solely for the Holder’s own account and not as a nominee for any other party, and for investment, and that the Holder will not offer, sell or otherwise dispose of this Warrant or any Warrant Units to be issued
upon exercise hereof except under circumstance that will not result in a violation of the Act or any state securities laws. Upon exercise of this Warrant, the Holder shall, if requested by the Company, confirm in writing, in a form satisfactory
to the Company, that the Warrant Units so purchased are being acquired solely for the Holder’s own account and not as a nominee for any other party, for investment, and not with a view toward distribution or resale. 
 (ii) This Warrant and all Warrant Units issued upon exercise hereof or conversion thereof shall be stamped or imprinted with a legend in
substantially the following form (in addition to any legend required by state securities laws):

THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT AND ANY OTHER APPLICABLE LAWS. 
 10. Lock Up. In the
event the Company shall undertake its first sale to the public pursuant to a registration statement of the Company filed under the Act, each Holder shall agree in writing, in form and substance customary for similar transactions, if requested by the
managing underwriter or underwriters hereof, not to lend, offer, pledge, sell, contract to sell (including, without limitation, any short sale), sell any option or contract to purchase, purchase any option or contract to sell, grant any option,
right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any Units or other securities of the Company convertible into or exercisable or exchangeable for Units held by such Holder immediately before the effective
date of the registration statement for such offering, or enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of Units (whether any such transaction as described in
this subsection is to be settled by delivery of Units or such other securities, in cash or otherwise, except for securities to be sold to such underwriter pursuant to such registration statement); provided, however, that: 
 (a) such period shall not exceed one hundred eighty (180) days after the effective date of the registration statement, except that
such 180-day period may be extended for not more than eighteen (18) days if such extension is reasonably necessary to allow the Company’s underwriters to comply with NASD Conduct Rule 2711 (or any similar successor rule); and

  

 6 








 (b) the Company’s directors, officers and holders of Units individually owning more
than one percent (1%) of the Company’s outstanding Units also agree to such limitations.
