to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume
the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the
right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized
by the Company in writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel
or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any issue between the position of the
Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses
of no more than one such separate counsel for all Purchaser Parties of all Purchasers;. The Company will not be liable to any Purchaser
Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which
shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is
attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser
Party in this Agreement. The Company shall not, without the prior written consent of the Purchaser Party, consent to entry of any judgment
or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Purchaser Party of a release from all liability in respect to such action or litigation, and such settlement shall
not include any admission as to fault on the part of the Purchaser Party.


 


4.6
Reservation of Common Stock. As of the Effective Date, the Company has reserved and the Company shall continue to reserve and
keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the
Company to issue Shares pursuant to this Agreement.


 


4.7
Listing of Common Stock. The Company hereby agrees to use best efforts to maintain the listing or quotation of the Common Stock
on the Trading Market on which it is currently listed, and the Company shall promptly secure the listing of all of the Shares on such
Trading Market (but in no event later than the Closing Date). The Company further agrees, if the Company applies to have the Common Stock
traded on any other Trading Market, it will then include in such application all of the Shares, and will take such other action as is
necessary to cause all of the Shares to be listed or quoted on such other Trading Market as promptly as possible. The Company will then
take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading Market and will comply in all
respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market.

4.8
Certain Transactions and Confidentiality. The Purchaser covenants that neither it nor any Affiliate acting on its behalf or pursuant
to any understanding with it will execute any purchases or sales, including Short Sales of any of the Company’s securities during
the period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement
are first publicly announced by the Company (it being understood and agreed that for all purposes of this Agreement, and without implication
that the contrary would otherwise be true, transactions, purchases and sales shall not include the location and/or reservation of borrowable
shares of Common Stock). The Purchaser covenants that until such time as the transactions contemplated by this Agreement are publicly
disclosed by the Company, the Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding
the foregoing, and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees
that (i) the Purchaser makes no representation, warranty or covenant hereby that it will not engage in effecting transactions in any
securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced by the Company,
(ii) the Purchaser shall not be restricted or prohibited from effecting any transactions in any securities of the Company in accordance
with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced
by the Company and (iii) the Purchaser shall have no duty of confidentiality to the Company or its Subsidiaries after the transactions
contemplated by this Agreement are first publicly announced by the Company. Notwithstanding the foregoing, in the case the Purchaser
is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Purchaser’s assets and
the portfolio managers have no actual knowledge of the investment decisions made by the portfolio managers managing other portions of
the Purchaser’s assets, the covenant set forth above shall only apply with respect to the portion of assets managed by the portfolio
manager that made the investment decision to purchase the Securities covered by this Agreement.
