of the Replacement Term Loan Lender and the undertakings of the Consenting Lenders are several.

 

(b) Replacement
Term Loans.

 

(i)
As of the Second Amendment Closing Date, the Replacement Term Loans shall be “Loans”, “Initial Term Loans”,
 “Term Loans”, “Replacement Term Loans” and “Additional Term Loans” under, and for all purposes
of, the Credit Agreement and the other Loan Documents. The Replacement Term Loans shall have the same terms as the Existing Term
Loans outstanding immediately prior to the Second Amendment Closing Date, other than to the extent expressly provided in this Agreement.
Without limiting the foregoing, the Replacement Term Loans shall have the same maturity date as the Existing Term Loans outstanding
immediately prior to the Second Amendment Closing Date. Upon the Second Amendment Closing Date, the Replacement Term Loans shall
be treated as part of the same Class for all purposes of the Credit Agreement and the other Loan Documents.

 

    2

     

    

 

(ii)
On the Second Amendment Closing Date, the proceeds of the Replacement Term Loans shall be applied to replace in full the
principal of all of the Existing Term Loans, on the terms and subject to the conditions set forth herein. Notwithstanding anything
herein or in the Credit Agreement to the contrary, the aggregate principal amount of the Replacement Term Loans shall not exceed
the aggregate principal amount of the Existing Term Loans outstanding immediately prior to the Second Amendment Closing Date.

 

(iii)
It is acknowledged and agreed that pursuant to the Cashless Settlement of Existing Term Loans, dated the date hereof, among
the Borrowers, Jefferies Finance LLC, as the New Lender (as defined therein), the Administrative Agent and each Consenting Lender
party thereto as an Existing Lender (as defined therein), each such Consenting Lender has waived any breakage loss, cost or expense
due and payable to it by the Borrower pursuant to Section 2.16 of the Credit Agreement with respect to the repayment of the Existing
Term Loans on a date other than the last day of the Interest Period relating to such Existing Term Loans.

 

(iv)
The Borrower and the Administrative Agent hereby consent to any assignments made by the Replacement Term Loan Lender or
any affiliate thereof to the Persons included in the list of allocations separately provided to the Borrower and the Administrative
Agent (or any Approved Funds or Affiliate of such Persons) in connection with the primary syndication of the Replacement Term Loans.

 

(c) Administrative
Agent Authorization. The Borrower, each Consenting Lender and the Replacement Term Loan Lender hereby authorize the Administrative
Agent to (i) determine all amounts, percentages and other information with respect to the Loans of each Lender, which amounts,
percentages and other information may be determined only upon receipt by the Administrative Agent of the Lender New Commitments
of the Consenting Lenders and (ii) enter and complete all such amounts, percentages and other information in the Register. The
Administrative Agent’s determination and entry and completion shall be conclusive evidence of the existence, amounts, percentages
and other information with respect to the obligations of the Borrower under the Credit Agreement, in each case, absent manifest
error.

 

SECTION
3. Incremental Term Loans.

 

(a) On the terms and
subject to the conditions set forth herein, the Incremental Term Loan Lender hereby agrees to make Incremental Term Loans to the
Borrowers on the Second Amendment Closing Date in an aggregate principal amount set forth opposite its name under the heading “Incremental
Term Commitment” on Schedule II hereto (each, an “Incremental Term Commitment” and collectively,
the “Incremental Term Commitments”). It is understood and agreed that, once funded, the Incremental Term Loans
shall be added to (and form part of) each Term Borrowing of outstanding Term Loans on a pro rata basis (based on the relative
sizes of the various outstanding Borrowings), so that each Term Lender will participate proportionately in each then outstanding
Term Borrowing. Interest will begin accruing on the Incremental Term Loans on the Second Amendment Closing Date. Unless previously
terminated, the Incremental Term Commitments shall terminate at 5:00 p.m., New York City time, on the Second Amendment Closing
Date. Amounts borrowed under this Section 3(a) and repaid or prepaid may not be reborrowed.

 

    3

     

    

 

(b) The Incremental
Term Loans shall be an “Incremental Facility” for all purposes of the Credit Agreement and the other Loan Documents.
The Incremental Term Loans shall have the same terms applicable to, and shall constitute, “Loans”, “Initial Term
Loans”, “Term Loans” and “Additional Term Loans” under the Credit Agreement. From and after the Second
Amendment Closing Date, the Incremental Term Loan Lender shall constitute an “Initial Term Lender”, a “Term Lender”,
an “Additional Lender” and a “Lender” for all purposes of the Credit Agreement and the other Loan Documents.
