paid in cash on such day and, to the extent not paid in cash, shall be paid as set forth in Section 2.4(b). If any date on which

Loans in full, (C) the occurrence of a Change of Control, or (D) the final maturity of the Loans (each, a “Conversion

of the Loans which constitutes Deferred Interest Principal, the number of shares of Limbach Stock (the “Conversion Shares”)

Lenders elect to receive the Conversion Shares, they shall notify the Borrower in writing of such election as follows: (i) in the
case of an acceleration of the Loans in full, on or prior to the Conversion Date, (ii) in the case of the final maturity of the
Loans, not less than thirty (30) days prior to the Conversion Date, and (iii) in the case of any other Conversion Event, within
five (5) days after notice by Borrower of such Conversion Event, which notice must be given to the Agent and the Lenders at least
ten (10) days prior to the Conversion Date. On the Conversion Date, at the election of the Required Lenders, the Borrower shall

Principal being converted and (ii) issue to the Lenders the number of shares of Limbach Stock equal to the Conversion Shares minus
the Liquidation Shares, in each case on a pro rata basis based on the Deferred Interest Principal owed to each such Lender; provided,
however, that if the Conversion Event occurs in connection with an acceleration of the loans in full, the Borrower shall deliver
such shares or cash within ten (10) days after the Conversion Date. Set forth on Schedule 2.4(b) is an example calculation of the
amount of cash and number of shares of Limbach Stock the Borrower would be required to deliver to the Lenders upon an exercise
of the option set forth in clause (y) of the foregoing sentence. The example calculation set forth on Schedule 2.4(b) is for illustrative

per annum equal to the sum of 3.00% per annum plus the Stated Interest Rate; provided, however, that in the absence of acceleration,
any increase in interest rates pursuant to this Section shall be made at the election of the Agent, acting at the request or with
the consent of the Required Lenders, with written notice to the Borrower (which election may be retroactively effective to the

other than Taxes which are not delinquent, except those that are being contested in good faith and by appropriate legal proceedings

(e)          Equity
Cure.

 

(i)          Cash
Equity Contribution Requirements. In the event the Borrower and its Subsidiaries fail to comply with the financial covenants

Equity Contribution”); provided that:

 

(A)         notice
of the Borrower’s intent to receive a Specified Equity Contribution shall be delivered in writing no later than the day on
which financial statements are required to be delivered for the applicable fiscal quarter,

 

(B)         the
amount of any Specified Equity Contribution will be no greater than the amount required to cause the Borrower to be in compliance
with such covenants,

 

(C)         all
Specified Equity Contributions will be disregarded for purposes of the calculation of EBITDA for all other purposes, including
calculating basket levels, pricing, determining compliance with incurrence based or pro forma calculations or conditions,

(D)         there
shall be no more than three (3) Specified Equity Contributions during the term of this Agreement,

Notwithstanding anything to the

giving effect thereto as set forth above no Event of Default would then exist under Section 6.20(a), (b), (c) and/or (d) on
a pro forma basis, the applicable Event(s) of Default under Section 6.20(a), (b), (c) and/or (d) shall be deemed cured.

 

(ii)         Other
Equity Cure Terms. Notwithstanding the foregoing, no single Specified Equity Contribution shall exceed $1,000,000 and the Specified
Equity Contributions shall not exceed $2,500,000 in the aggregate during the term of this Agreement. In the event that (A) no
Event of Default exists other than that arising due to the failure of the Loan Parties to comply with the financial covenants set
forth in Section 6.20(a), (b). (c) or (d), and (B) such Specified Equity Contribution if fully consummated would be sufficient
in accordance with the terms hereof to cause the Borrower and its Subsidiaries to be in compliance with Section 6.20(a), (b),
(c) and/or (d), as applicable, as of the relevant date of determination, then from and following the date of the occurrence of
the applicable Event of Default and until the date that is the earlier of (x) fifteen (15) days subsequent to the date the
applicable financial statements are required to be delivered and (y) the date, if any, on which the Borrower notifies the
Agent in writing that such Specified Equity Contribution shall not be exercised, then neither Agent nor any Lender shall exercise
any remedies set forth in Section 2.4(c) or Section 7 during such period solely as a result of the existence of such
Event of Default; provided, that in the event notice of such Specified Equity Contribution is given but such Specified Equity
Contribution is not exercised, the Agent (acting at the request or with the consent of the Required Lenders) may elect pursuant
to Section 2.4(c) to have the outstanding Obligations accrue interest at the default rates effective retroactively from the
date of the occurrence of the applicable Event of Default.

 

Section 6.21.         Compliance
with Sanctions Programs.  (a) Each Loan Party shall at all times comply with the requirements of all Sanctions Programs
applicable to such Loan Party and shall cause each of its Subsidiaries to comply with the requirements of all Sanctions Programs

(c)          If
any Loan Party obtains actual knowledge or receives any written notice that such Loan Party, any of its officers or directors,
any Affiliate, or any Subsidiary is named on any then current Sanctions List (such occurrence, a “Sanctions Event”),
such Loan Party shall promptly (i) give written notice to the Agent and the Lenders of such Sanctions Event, and (ii) comply with
all applicable laws with respect to such Sanctions Event (regardless of whether the party included on the Sanctions List is located
within the jurisdiction of the United States of America), including the Sanctions Programs, and each Loan Party hereby authorizes
and consents to the Agent and the Lenders taking any and all steps the Agent or the Lenders deem necessary, in their sole but reasonable
discretion, to avoid violation of all applicable laws with respect to any such Sanctions Event, including the requirements of the
Sanctions Programs (including the freezing and/or blocking of assets and reporting such action to OFAC and/or the U.S. Department
of Treasury’s Office of Foreign Assets Control).

 

(d)          No
Loan Party will use any proceeds of the Loans to finance or otherwise fund, directly or indirectly, (i) any activity or business
with or related to any Sanctioned Person or any Sanctioned Country or (ii) in any other manner that will result in a violation
of any Sanctions Program by any Person (including any Person participating in the Loans, whether as lender, underwriter, advisor,
investor, or otherwise).

Debt. No Loan Party shall, nor shall it permit any of its Subsidiaries to, (a) amend or modify any of the terms or conditions
relating to Subordinated Debt, (b) make any voluntary prepayment of Subordinated Debt or effect any voluntary redemption thereof;

prior to, and after giving pro forma effect to, the voluntary prepayment, (A) the Total Leverage Ratio shall be no greater
than 0.25 less than the most recently applicable Total Leverage Ratio required under Section 6.20(a), (B) the Loan Parties are
in compliance with the most recently applicable covenants set forth in Sections 6.20(c) and (d), (C) no Default or Event of Default
shall exist, and (D) the Borrower has (x) Unused Revolving Credit Commitments (as defined in the Senior Credit Agreement) plus
unrestricted cash and Cash Equivalents and (y) Borrowing Base Availability (as defined in the Senior Credit Agreement) plus unrestricted
cash and Cash Equivalents, in each case, of at least $10,000,000, and (ii) the Borrower has delivered to the Agent a compliance
certificate in the form of Exhibit E attached hereto evidencing compliance with the financial covenants as set forth above, or

applicable Subordination Agreement. Notwithstanding the foregoing, the Loan Parties may agree to a decrease in the interest rate
applicable thereto or to a deferral of repayment of any of the principal of or interest on the Subordinated Debt beyond the current
due dates therefor.

that is contractually subordinated in right of payment to any Senior Facility Debt unless such Indebtedness is subordinate in right
of payment to the Obligations to at least the same extent as the Obligations are subordinate in right of payment to such Senior
Facility Debt. For the avoidance of doubt, this provision shall not be deemed to permit any Indebtedness other than permitted Indebtedness

interest on all outstanding Loans to be forthwith due and payable and thereupon all outstanding Loans, including both principal
and interest thereon, shall be and become immediately due and payable together with all other amounts payable under the Loan Documents

Section 7.1(c) or this Section 7.2, shall also promptly send a copy of such notice to the other Lenders, but the failure
to do so shall not impair or annul the effect of such notice.

Section 7.3.          Bankruptcy
Defaults. When any Event of Default described in subsections (j) or (k) of Section 7.1 exists, then all outstanding
Obligations shall immediately and automatically become due and payable together with all other amounts payable under the Loan Documents

Section 7.4.          [Reserved].

 

Section 7.5.          Notice
of Default. The Agent shall give notice to the Borrower under Section 7.1(c) promptly upon being requested to do so by

Section 8.1.          [Reserved].

 

Section 8.2.          [Reserved].

 

Section 8.3.          [Reserved].

 

Section 8.4.          Increased
Costs. (a) Increased Costs Generally. If any Change in Law shall:

 

(i)          impose,
modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets
of, deposits with or for the account of, or credit extended or participated in by, any Lender;

 

(ii)         subject
any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition
of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations,
or its deposits, reserves, other liabilities or capital attributable thereto; or

 

(iii)        impose
on any Lender any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or
participation therein;

 

and the result of any of the foregoing
shall be to increase the cost to such Lender or such other Recipient of making, converting to, continuing or maintaining any Loan
or of maintaining its obligation to make any such Loan, or to reduce the amount of any sum received or receivable by such Lender
or other Recipient hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or other Recipient,
the Borrower will pay to such Lender or other Recipient, as the case may be, such additional amount or amounts as will compensate
such Lender or other Recipient, as the case may be, for such additional costs incurred or reduction suffered.

 

    	 	-60-	 

     

    

 

(b)          Capital
Requirements. If any Lender determines that any Change in Law affecting such Lender or any lending office of such Lender or
such Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing
the rate of return on such Lender’s capital or on the capital of such Lender’s holding company, if any, as a consequence
of this Agreement or the Loans made by such Lender to a level below that which such Lender or such Lender’s holding company
could have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such
Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender such
additional amount or amounts as will compensate such Lender or such Lender’s or holding company for any such reduction suffered.

 

(c)          Certificates
for Reimbursement. A certificate of a Lender setting forth the amount or amounts necessary to compensate such Lender or its
holding company, as the case may be, as specified in Section 8.4(a) or (b) above which shall include the basis for and calculation
of such requested compensation and delivered to the Borrower, shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within ten (10) Business Days after receipt thereof.

 

(d)          Delay
in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section shall not constitute
a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be required to
compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than nine months prior
to the date that such Lender notifies the Borrower of the Change in Law giving rise to such increased costs or reductions, and
of such Lender’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased
costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive
effect thereof).

 

Section 9.          The
Agent.

 

Section 9.1.          Appointment
and Authorization of Agent. Each Lender hereby appoints Alcentra Capital Corporation, a Maryland corporation, to act on its
behalf as the Agent under the Loan Documents and authorizes the Agent to take such action as Agent on its behalf and to exercise
such powers under the Loan Documents as are delegated to the Agent by the terms thereof, together with such actions and powers
as are reasonably incidental thereto. The provisions of this Section 9 are solely for the benefit of the Agent and the Lenders,
and neither the Borrower nor any other Loan Party shall have rights as a third-party beneficiary of any of such provisions. It
is understood and agreed that the use of the term “agent” in this Agreement or in any other Loan Document (or any other
similar term) with reference to the Agent is not intended to connote any fiduciary or other implied (or express) obligations arising
under agency doctrine of any applicable law. Instead such term is used as a matter of market custom, and is intended to create
or reflect only an administrative relationship between contracting parties.

 

    	 	-61-	 

     

    

 

Section 9.2.          Agent
and Its Affiliates. The Agent shall have the same rights and powers in its capacity as a Lender as any other Lender and may
exercise or refrain from exercising such rights and powers as though it were not the Agent, and the Agent and its Affiliates may
accept deposits from, lend money to, own securities of, act as the financial advisor or in any other advisory capacity for, and
generally engage in any kind of banking, trust, financial advisory, or other business with any Loan Party or any Affiliate of any
Loan Party as if it were not the Agent under the Loan Documents and without any duty to account therefor to the Lenders. The terms
“Lender” and “Lenders”, unless otherwise expressly indicated or unless the context otherwise
clearly requires, includes the Agent in its individual capacity as a Lender.

 

Section 9.3.          Exculpatory
Provisions. (a) The Agent shall not have any duties or obligations except those expressly set forth herein and in the other
Loan Documents, and its duties hereunder shall be administrative in nature. Without limiting the generality of the foregoing, the
Agent and its Related Parties:

 

(i)          shall
not be subject to any fiduciary or other implied duties, regardless of whether a Default or Event of Default has occurred and is
continuing;

 

(ii)         shall
not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by the other Loan Documents that the Agent is required to exercise as directed in writing by the
Required Lenders (or such other number or percentage of the Lenders as shall be expressly provided for herein or in the other Loan
Documents); provided that the Agent shall not be required to take any action that, in its opinion or the opinion of its
counsel, may expose the Agent to liability or that is contrary to any Loan Document or any Legal Requirement, including for the
avoidance of doubt any action that may be in violation of the automatic stay under any Debtor Relief Law, and the Agent shall in
all cases be fully justified in failing or refusing to act hereunder or under any other Loan Document unless it first receives
any further assurances of its indemnification from the Lenders that it may require, including prepayment of any related expenses
and any other protection it requires against any and all costs, expense, and liability which may be incurred by it by reason of
taking or continuing to take any such action; and

 

(iii)        shall
not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and shall not be liable for
the failure to disclose, any information relating to any Loan Party or any of its Affiliates that is communicated to or obtained
by the Person serving as the Agent or any of its Affiliates in any capacity.

 

(b)          Any
instructions of the Required Lenders (or such other number or percentage of the Lenders as shall be necessary, or as the Agent
shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.10) shall be binding upon
all the Lenders. Neither the Agent nor any of its Related Parties shall be liable for any action taken or not taken by the Agent
(i) with the consent or at the request of the Required Lenders (or such other number or percentage of the Lenders as shall
be necessary, or as the Agent shall believe in good faith shall be necessary, under the circumstances as provided in Section 10.10),
or (ii) in the absence of its own gross negligence or willful misconduct as determined by a court of competent jurisdiction
by final and nonappealable judgment. In all cases in which the Loan Documents do not require the Agent to take specific action,
the Agent shall be fully justified in using its discretion in failing to take or in taking any action thereunder. The Agent shall
be entitled to assume that no Default or Event of Default exists, and shall be deemed not to have knowledge of any Default or Event
of Default, unless and until notice describing such Default is given to the Agent in writing by the Borrower or a Lender. If the
Agent receives from any Loan Party a written notice of an Event of Default pursuant to Section 6.1, the Agent shall promptly
give each of the Lenders written notice thereof.

 

    	 	-62-	 

     

    

 

(c)          Neither
the Agent nor any of its Related Parties shall be responsible for or have any duty to ascertain or inquire into (i) any statement,
warranty or representation made in or in connection with this Agreement or any other Loan Document, or the advancing of the Loans,
(ii) the contents of any certificate, report or other document delivered under this Agreement or any other Loan Documents
or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms
or conditions set forth herein or therein or the occurrence of any Default or Event of Default, (iv) the validity, enforceability,
effectiveness, genuineness, value, worth, or collectability of this Agreement, any other Loan Document or any other agreement,
instrument, document or writing furnished in connection with any Loan Document, or (v) the satisfaction of any condition set forth
in Section 3 or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Agent;
and the Agent makes no representation of any kind or character with respect to any such matter mentioned in this sentence.

 

Section 9.4.          Reliance
by Agent. The Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing (including any electronic message, Internet or intranet
website posting or other distribution) believed by it to be genuine and to have been signed, sent or otherwise authenticated by
the proper Person. The Agent also may rely upon any statement made to it orally or by telephone and believed by it to have been
made by the proper Person, and shall not incur any liability for relying thereon. In determining compliance with any condition
hereunder to the making of a Loan that by its terms must be fulfilled to the satisfaction of a Lender, the Agent may presume that
such condition is satisfactory to such Lender unless the Agent shall have received notice to the contrary from such Lender prior
to the making of such Loan. The Agent may consult with legal counsel (who may be counsel for the Borrower), independent accountants
and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice
of any such counsel, accountants or experts. The Agent may treat the payee of any Note or any Loan as the holder thereof until
written notice of transfer shall have been filed with the Agent signed by such payee in form satisfactory to the Agent.

 

Section 9.5.          Delegation
of Duties. The Agent may perform any and all of its duties and exercise its rights and powers hereunder or under any other
Loan Document by or through any one or more sub-agents appointed by the Agent. The Agent and any such sub-agent may perform any
and all of its duties and exercise its rights and powers by or through their respective Related Parties. The exculpatory provisions
of this Section 9 shall apply to any such sub-agent and to the Related Parties of the Agent and any such sub-agent, and shall apply
to their respective activities in connection with the syndication of the Facilities as well as activities as Agent. The Agent shall
not be responsible for the negligence or misconduct of any sub-agents except to the extent that a court of competent jurisdiction
determines in a final and nonappealable judgment that the Agent acted with gross negligence or willful misconduct in the selection
of such sub-agents.

 

    	 	-63-	 

     

    

 

Section 9.6.          Non-Reliance
on Agent and Other Lenders. Each Lender acknowledges that it has, independently and without reliance upon the Agent or any
other Lender or any of their Related Parties and based on such documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without
reliance upon the Agent or any other Lender or any of their Related Parties and based on such documents and information as it shall
from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this
Agreement, any other Loan Document or any related agreement or any document furnished hereunder or thereunder.

 

Section 9.7.          Resignation
of Agent and Successor Agent. (a) The Agent may at any time give notice of its resignation to the Lenders and the Borrower.
Upon receipt of any such notice of resignation, the Required Lenders shall have the right, in consultation with the Borrower, to
appoint a successor and, so long as no Event of Default shall have occurred and be continuing, such appointment shall be within
the Borrower’s consent (which shall not be unreasonably withheld). If no such successor shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty (30) days after the retiring Agent gives notice of
its resignation (or such earlier day as shall be agreed by the Required Lenders) (the “Resignation Effective Date”),
then the retiring Agent may (but shall not be obligated to), on behalf of the Lenders, appoint a successor Agent meeting the qualifications
set forth above. Whether or not a successor has been appointed, such resignation shall become effective in accordance with such
notice on the Resignation Effective Date.

 

(b)          [Reserved].

 

(c)          With
effect from the Resignation Effective Date (1) the retiring or removed Agent shall be discharged from its duties and obligations
hereunder and under the other Loan Documents (except that in the case of any collateral security held by the Agent on behalf of
the Lenders under any of the Loan Documents, the retiring or removed Agent shall continue to hold such collateral security until
such time as a successor Agent is appointed) and (2) except for any indemnity payments owed to the retiring or removed Agent, all
payments, communications and determinations provided to be made by, to or through the Agent shall instead be made by or to each
Lender directly, until such time, if any, as the Required Lenders appoint a successor Agent as provided for above. Upon the acceptance
of a successor’s appointment as Agent hereunder, such successor shall succeed to and become vested with all of the rights,
powers, privileges and duties of the retiring or removed Agent (other than any rights to indemnity payments owed to the retiring
or removed Agent), and the retiring or removed Agent shall be discharged from all of its duties and obligations hereunder or under
the other Loan Documents. The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrower and such successor. After the retiring or removed Agent’s resignation or removal
hereunder and under the other Loan Documents, the provisions of this Section 9 and Section 10.12 shall continue in effect
for the benefit of such retiring or removed Agent, its sub-agents and their respective Related Parties in respect of any actions
taken or omitted to be taken by any of them while the retiring or removed Agent was acting as Agent.

Section 9.9.          [Reserved].

 

Section 9.10.         No
Other Duties; Designation of Additional Agents. The Agent shall have the continuing right, for purposes hereof, at any time
and from time to time to designate one or more of the Lenders (and/or its or their Affiliates) as “syndication agents,”
“documentation agents,” “arrangers” or other designations for purposes hereto, but such designation shall
have no substantive effect, and such Lenders and their Affiliates shall have no additional powers, duties or responsibilities as
a result thereof; provided that if at any time there is no Person acting as Agent hereunder and under the other Loan Documents,
then (i) the Required Lenders shall have the rights otherwise given to the Agent pursuant to this Section 9 and (ii) subject
to Section 10.7, any Lender may, with the consent of the Required Lenders, enforce any rights and remedies available to it and
as authorized by the Required Lenders.

 

Section 9.11.         Authorization
to Enter into, and Enforcement of the Guaranty. The Lenders irrevocably authorize the Agent to execute and deliver the Senior
Subordination Agreement, the Surety Subordination Agreement, each Subordination Agreement and each Guaranty Agreement on their
behalf and on behalf of each of their Affiliates and to take such action and exercise such powers under the Senior Subordination
Agreement, the Surety Subordination Agreement, any Subordination Agreement or any Guaranty Agreement as the Agent considers appropriate,
provided the Agent shall not amend the Senior Subordination Agreement, the Surety Subordination Agreement, any Subordination
Agreement or any Guaranty Agreement unless such amendment is agreed to in writing by the Required Lenders. Each Lender acknowledges
and agrees that it will be bound by the terms and conditions of the Senior Subordination Agreement, the Surety Subordination Agreement,
each Subordination Agreement and each Guaranty Agreement upon the execution and delivery thereof by the Agent. Except as otherwise
specifically provided for herein, no Lender (or its Affiliates) other than the Agent shall have the right to institute any suit,
action or proceeding in equity or at law for the execution of any trust or power in respect of any Guaranty Agreement or for the
appointment of a receiver or for the enforcement of any other remedy under any Guaranty Agreement.

 

Section 9.12.         Agent
May File Proofs of Claim. In case of the pendency of any proceeding under any Debtor Relief Law, the Agent (irrespective of
whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective
of whether the Agent shall have made any demand on the Borrower) shall be entitled and empowered (but not obligated), by intervention
in such proceeding or otherwise:

 

(a)          to
file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans and all other
Obligations that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims
of the Lenders and the Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the
Lenders and the Agent and their respective agents and counsel and all other amounts due the Lenders and the Agent under Sections
2.13 and 10.12(a)) allowed in such judicial proceeding; and

 

    	 	-65-	 

     

    

 

(b)          to
collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same;

 

and any custodian, receiver, assignee,
trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender
to make such payments to the Agent and, in the event that the Agent shall consent to the making of such payments directly to the
Lenders, to pay to the Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Agent
and its agents and counsel, and any other amounts due the Agent under Sections 2.13 and 10.12(a). Nothing contained herein shall
be deemed to authorize the Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization,
arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Agent to vote
in respect of the claim of any Lender in any such proceeding.

 

Section 9.13.         Guaranty
Matters. The Lenders irrevocably authorize the Agent, at its option and in its discretion, to release any Guarantor from its
obligations under its Guaranty Agreement if such Person ceases to be a Loan Party as a result of a transaction permitted under
the Loan Documents. Upon request by the Agent at any time, the Required Lenders will confirm in writing the Agent’s authority
to release any Guarantor from its obligations under its Guaranty Agreement pursuant to this Section 9.13.

 

Section 10.         Miscellaneous.

 

Section 10.1.          Taxes.
(a) FATCA. For purposes of this Section 10.1, the term “applicable law” includes FATCA.

 

(b)          Payments
Free of Taxes. Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made
without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the
good faith discretion of an applicable Withholding Agent) requires the deduction or withholding of any Tax from any such payment
by a Withholding Agent, then the applicable Withholding Agent shall be entitled to make such deduction or withholding and shall
timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if
such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after
such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under
this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding
been made.

 

    	 	-66-	 

     

    

 

(c)          Payment
of Other Taxes by the Loan Parties. Each Loan Party shall timely pay to the relevant Governmental Authority in accordance
with applicable law, or at the option of the Agent timely reimburse it for the payment of, any Other Taxes.

 

(d)          Indemnification
by the Loan Parties. The Loan Parties shall jointly and severally indemnify each Recipient, within ten (10) days after demand
therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts
payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient
and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability
delivered to the Borrower by a Lender (with a copy to the Agent), or by the Agent on its own behalf or on behalf of a Lender, shall
be conclusive absent manifest error.

 

(e)          Indemnification
by the Lenders. Each Lender shall severally indemnify the Agent, within ten (10) days after demand therefor, for (i) any Indemnified
Taxes attributable to such Lender (but only to the extent that the Loan Parties have not already indemnified the Agent for such
Indemnified Taxes and without limiting the obligation of the Loan Parties to do so), (ii) any Taxes attributable to such Lender’s
failure to comply with the provisions of Section 10.9(d) relating to the maintenance of a Participant Register and (iii) any Excluded
Taxes attributable to such Lender, in each case, that are payable or paid by the Agent in connection with any Loan Document, and
any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed
or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any
Lender by the Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Agent to set off and apply any
and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Agent to the Lender from any
other source against any amount due to the Agent under this Section 10.1(e).

 

(f)          Evidence
of Payments. As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this
Section 10.1, such Loan Party shall deliver to the Agent the original or a certified copy of a receipt issued by such Governmental
Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory
to the Agent.

 

(g)          Status
of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made
under any Loan Document shall deliver to the Borrower and the Agent, at the time or times reasonably requested by the Borrower
or the Agent, such properly completed and executed documentation reasonably requested by the Borrower or the Agent as will permit
such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested
by the Borrower or the Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the
Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding
or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion,
execution and submission of such documentation (other than such documentation set forth in Section 10.1(g)(ii)(A), (ii)(B) and
(ii)(D) below) shall not be required if in the Lender’s reasonable judgment such completion, execution or submission would
subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position
of such Lender.

 

    	 	-67-	 

     

    

 

(ii)         Without
limiting the generality of the foregoing,

 

(A)         any
Lender that is a U.S. Person shall deliver to the Borrower and the Agent on or prior to the date on which such Lender becomes a
Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed
originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax;

 

(B)         any
Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number of copies
as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement
(and from time to time thereafter upon the reasonable request of the Borrower or the Agent), whichever of the following is applicable:

 

(i)          in
the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect
to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN or W-8BEN-E, as applicable, establishing
an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article of such tax treaty
and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or W-8BEN-E, as applicable, establishing
an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “business profits” or “other
income” article of such tax treaty;

 

(ii)         executed
originals of IRS Form W-8ECI;

 

(iii)        in
the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x)
a certificate in form reasonably acceptable to the Agent representing that such Foreign Lender is not a “bank” within
the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the Borrower within the meaning of Section
881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code (a “U.S.
Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN or W-8BEN-E, as applicable; or

 

(iv)        
to the extent a Foreign Lender is not the beneficial owner, executed originals of IRS Form W-8IMY, accompanied by IRS Form W-8ECI,
IRS Form W-8BEN or W-8BEN-E, as applicable, a U.S. Tax Compliance Certificate in form reasonably acceptable to the Agent, IRS Form
W-9, and/or other certification documents from each beneficial owner, as applicable; provided that if the Foreign Lender
is a partnership and one or more direct or indirect partners of such Foreign Lender are claiming the portfolio interest exemption,
such Foreign Lender may provide a U.S. Tax Compliance Certificate in form reasonably acceptable to the Agent on behalf of each
such direct and indirect partner;

 

    	 	-68-	 

     

    

 

(C)         
any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Agent (in such number
of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this
Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Agent), executed originals of any
other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax,
duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or
the Agent to determine the withholding or deduction required to be made; and

 

(D)         if
a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender
were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b)
of the Code, as applicable), such Lender shall deliver to the Borrower and the Agent at the time or times prescribed by law and
at such time or times reasonably requested by the Borrower or the Agent such documentation prescribed by applicable law (including
as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or
the Agent as may be necessary for the Borrower and the Agent to comply with their obligations under FATCA and to determine that
such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from
such payment. Solely for purposes of this clause (D), “FATCA” shall include any amendments made to FATCA after the
date of this Agreement.

 

Each Lender agrees
that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update
such form or certification or promptly notify the Borrower and the Agent in writing of its legal inability to do so.

 

(h)          Treatment
of Certain Refunds. If any party determines, in its sole discretion exercised in good faith, that it has received a refund
of any Taxes as to which it has been indemnified pursuant to this Section 10.1 (including by the payment of additional amounts
pursuant to this Section 10.1), it shall pay to the indemnifying party an amount equal to such refund (but only to the extent of
indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out of pocket expenses
(including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority
with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified
party the amount paid over pursuant to this Section 10.1(h) (plus any penalties, interest or other charges imposed by the
relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental
Authority. Notwithstanding anything to the contrary in this Section 10.1(h), in no event will the indemnified party be required
to pay any amount to an indemnifying party pursuant to this Section 10.1(h) the payment of which would place the indemnified
party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification
had not been deducted, withheld, or otherwise imposed and the indemnification payments or additional amounts giving rise to such
refund had never been paid. This Section 10.1(h) shall not be construed to require any indemnified party to make available
its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other
Person.

 

    	 	-69-	 

     

    

 

(i)          Required
Elections. In the event that the Borrower is classified as a partnership for federal income tax purposes, or any taxable years
for which Sections 6221 through 6241 of the Code apply to the Borrower, the partnership representative shall, to the extent eligible,
make the election under Section 6221(b) of the Code with respect to the Borrower and take any other action such as disclosures
and notifications necessary to effectuate such election. If the election described in the preceding sentence is not available,
to the extent applicable, the partnership representative shall make the election under Section 6226(a) of the Code with respect
to the Borrower and take any other action such as filings, disclosures and notifications necessary to effectuate such election.

 

(j)          Survival.
Each party’s obligations under this Section 10.1 shall survive the resignation or replacement of the Agent or any assignment
of rights by, or the replacement of, a Lender and the repayment, satisfaction or discharge of all obligations under any Loan Document.

 

Section 10.2.          Mitigation
Obligations; Replacement of Lenders. (a) Designation of a Different Lending Office. If any Lender requests compensation
under Section 8.4, or requires the Borrower to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 10.1, then such Lender shall (at the request of the Borrower)
use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights
and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation
or assignment (i) would eliminate or reduce amounts payable pursuant to Section 8.4 or Section 10.1, as the
case may be, in the future, and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise
be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment.

 

(b)          Replacement
of Lenders. If any Lender requests compensation under Section 8.4, or if the Borrower is required to pay any Indemnified
Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 10.1
and, in each case, such Lender has declined or is unable to designate a different lending office in accordance with Section 10.2(a),
or if any Lender is a Non-Consenting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender
and the Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions
contained in, and consents required by, Section 10.9(b)), all of its interests, rights (other than its existing rights to
payments pursuant to Section 8.4 or Section 10.1) and obligations under this Agreement and the related Loan Documents to an Eligible
Assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided
that:

 

    	 	-70-	 

     

    

 

(i)          the
Borrower shall have paid to the Agent the assignment fee (if any) specified in Section 10.9(b)(iv);

 

(ii)         such
Lender shall have received payment of an amount equal to the outstanding principal of its Loans, accrued interest thereon, accrued
fees and all other amounts payable to it hereunder and under the other Loan Documents from the assignee (to the extent of such
outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts);

 

(iii)        in
the case of any such assignment resulting from a claim for compensation under Section 8.4 or payments required to be made
pursuant to Section 10.1 such assignment will result in a reduction in such compensation or payments thereafter;

 

(iv)        such
assignment does not conflict with applicable law; and

 

(v)         in
the case of any assignment resulting from a Lender becoming a Non-Consenting Lender, the applicable Eligible Assignee shall have
consented to the applicable amendment, waiver or consent.

 

A Lender shall not be required
to make any such assignment or delegation if, prior thereto, as a result of a waiver by such Lender or otherwise, the circumstances
entitling the Borrower to require such assignment and delegation cease to apply.

 

Section 10.3.          No
Waiver, Cumulative Remedies. No delay or failure on the part of the Agent or any Lender or on the part of the holder or holders
of any of the Obligations in the exercise of any power or right under any Loan Document shall operate as a waiver thereof or as
an acquiescence in any default, nor shall any single or partial exercise of any power or right preclude any other or further exercise
thereof or the exercise of any other power or right. The rights and remedies hereunder of the Agent, the Lenders and of the holder
or holders of any of the Obligations are cumulative to, and not exclusive of, any rights or remedies which any of them would otherwise
have.

 

Section 10.4.          Non-Business
Days. If the payment of any obligation or the performance of any covenant, duty or obligation hereunder becomes due and payable
on a day which is not a Business Day, the due date of such payment or performance shall be extended to the next succeeding Business
Day on which date such payment or performance shall be due and payable. In the case of any payment of principal falling due on
a day which is not a Business Day, interest on such principal amount shall continue to accrue during such extension at the rate
per annum then in effect, which accrued amount shall be due and payable on the next scheduled date for the payment of interest.

 

    	 	-71-	 

     

    

 

Section 10.5.          Survival
of Representations. All representations and warranties made herein or in any other Loan Document or in certificates given pursuant
hereto or thereto shall survive the execution and delivery of this Agreement and the other Loan Documents, and shall continue in
full force and effect with respect to the date as of which they were made as long as any Obligations (other than contingent obligations
not due and owing) remain unpaid hereunder.

 

Section 10.6.          Survival
of Indemnities. All indemnities and other provisions relative to reimbursement to the Lenders of amounts sufficient to protect
the yield of the Lenders with respect to the Loans, including, but not limited to, Sections 8.1, 8.4, 10.4 and 10.13, shall survive
the termination of this Agreement and the other Loan Documents and the payment of the Obligations (other than contingent obligations
not due and owing).

 

Section 10.7.          Sharing
of Payments by Lenders. If any Lender shall, by exercising any right of setoff or counterclaim or otherwise, obtain payment
in respect of any principal of or interest on any of its Loans or other Obligations hereunder resulting in such Lender receiving
payment of a proportion of the aggregate amount of its Loans and accrued interest thereon or other such Obligations greater than
its pro rata share thereof as provided herein, then the Lender receiving such greater proportion shall (a) notify the
Agent of such fact, and (b) purchase (for cash at face value) participations in the Loans and such other obligations of the
other Lenders, or make such other adjustments as shall be equitable, so that the benefit of all such payments shall be shared by
the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and
other amounts owing them; provided that:

 

(i)          if
any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations
shall be rescinded and the purchase price restored to the extent of such recovery, without interest; and

 

(ii)         the
provisions of this Section 10.7 shall not be construed to apply to (x) any payment made by the Borrower pursuant to and in
accordance with the express terms of this Agreement, or (y) any payment obtained by a Lender as consideration for the assignment
of or sale of a participation in any of its Loans to any assignee or participant, other than to any Loan Party (as to which the
provisions of this Section 10.7 shall apply).

 

Each Loan Party consents to the foregoing
and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to
the foregoing arrangements may exercise against each Loan Party rights of setoff and counterclaim with respect to such participation
as fully as if such Lender were a direct creditor of each Loan Party in the amount of such participation.

(including e-mail and Internet or intranet websites) pursuant to procedures approved by the Agent. The Agent or the Borrower may,

Unless the Agent otherwise

by written notice to the other parties hereto. In addition, each Lender agrees to notify the Agent from time to time to ensure

Section 10.9.          Successors
and Assigns; Assignments and Participations.  (a)  Successors and Assigns Generally. The provisions
of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Borrower may not assign or otherwise transfer any of its rights or obligations under any Loan
Document without the prior written consent of the Agent and each Lender, and no Lender may assign or otherwise transfer any of
its rights or obligations hereunder except (i) to an Eligible Assignee in accordance with the provisions of Section 10.9(b)
below, (ii) by way of participation in accordance with the provisions of Section 10.9(d) below or (iii) by way of pledge
or assignment of a security interest subject to the restrictions of Section 10.9(f) below (and any other attempted assignment or

upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby, Participants to the extent
provided in Section 10.9(d) below and, to the extent expressly contemplated hereby, the Related Parties of each of the Agent and
the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

 

    	 	-74-	 

     

    

 

(b)          Assignments
by Lenders. Any Lender may at any time assign to one or more Eligible Assignees all or a portion of its rights and obligations
under this Agreement (including all or a portion of the Loans at the time owing to it); provided that any such assignment
shall be subject to the following conditions:

 

(i)          Minimum
Amounts.

 

(A)         In
the case of an assignment of the entire remaining amount of the Loans at the time owing to the assigning Lender or contemporaneous
assignments to related Approved Funds that equal at least the amount specified in Section 10.9(b)(i)(B) below in the aggregate
or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned;

 

(B)         
In any case of an assignment not described in Section 10.9(b)(i)(A) above, the principal outstanding balance of the Loans
of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to
such assignment is delivered to the Agent or, if “Trade Date” is specified in the Assignment and Assumption,
as of the Trade Date) shall not be less than $1,000,000, unless each of the Agent and, so long as no Event of Default has occurred
and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed).

 

(ii)         Proportionate
Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s
rights and obligations under this Agreement with respect to the Loan assigned.

 

(iii)        Required

in addition:

 

(A)         the
consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default
has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender
or an Approved Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall
object thereto by written notice to the Agent within five (5) Business Days after having received notice thereof; and

 

(B)         the
consent of the Agent (such consent not to be unreasonably withheld, delayed, or conditioned) shall be required for assignments

Assignment to Certain Persons. No Lender shall assign any of its rights or obligations hereunder to the Borrower or any of
the Borrower’s Affiliates or Subsidiaries.

 

(vi)        No
Assignment to Natural Persons. No such assignment shall be made to a natural person.

 

Subject to acceptance and recording thereof
by the Agent pursuant to Section 10.9(c), from and after the effective date specified in each Assignment and Assumption, the
Eligible Assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment
and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to
the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and,
in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement,
such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 8.1, 8.4, 10.1
and 10.12 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer
by a Lender of rights or obligations under this Agreement that does not comply with this paragraph shall be treated for purposes
of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 10.9(d)
below.

 

(c)          Register.
The Agent, acting solely for this purpose as an agent of the Borrower (such agency being solely for tax purposes), shall maintain
a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders,
and the principal amounts (and stated interest) of the Loans owing to, each Lender pursuant to the terms hereof from time to time
(the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the
Agent and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder
for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable
time and from time to time upon reasonable prior notice.

 

(d)          Participations.
Any Lender may at any time, without the consent of, or notice to, the Borrower or the Agent, sell participations to any Person
(other than a natural person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”)
in all or a portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of the Loans
owing to it); provided that (i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (iii) the Borrower,
the Agent and the Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights
and obligations under this Agreement. For the avoidance of doubt, each Lender shall be responsible for the indemnity under Section
10.12(c) with respect to any payments made by such Lender to its Participant(s).

 

    	 	-76-	 

     

    

 

Any agreement or instrument
pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement
or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification
or waiver described in Section 10.10(i) and (ii) that affects such Participant. The Borrower agrees that each Participant
shall be entitled to the benefits of Sections 8.1, 8.4, and 10.1 (subject to the requirements and limitations therein, including
the requirements under Section 10.1(g) (it being understood that the documentation required under Section 10.1(g) shall be delivered
to the participating Lender)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to
Section 10.9(b) above; provided that such Participant (A) agrees to be subject to the provisions of Section 10.2 as
if it were an assignee under Section 10.2(b) above; and (B) shall not be entitled to receive any greater payment under Section 8.4
or Section 10.1, with respect to any participation, than its participating Lender would have been entitled to receive, except
to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired
the applicable participation. Each Lender that sells a participation agrees, at the Borrower's request and expense, to use reasonable
efforts to cooperate with the Borrower to effectuate the provisions of Section 10.2(b) with respect to any Participant. To
the extent permitted by law, each Participant also shall be entitled to the benefits of Section 10.13 as though it
were a Lender; provided that such Participant agrees to be subject to Section 10.7 as though it were a Lender. Each
Lender that sells a participation shall, acting solely for this purpose as an agent of the Borrower, maintain a register on which
it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s
interest in the Loans or other obligations under the Loan Documents (the “Participant Register”); provided
that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of
any Participant or any information relating to a Participant’s interest in any Loans or its other Obligations under any Loan
Document) to any Person except to the extent that such disclosure is necessary to establish that such Loan or other Obligation
is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register
shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register
as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance
of doubt, the Agent (in its capacity as Agent) shall have no responsibility for maintaining a Participant Register.

 

(e)          Certain
Pledges. Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement
to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided
that no such pledge or assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee
or assignee for such Lender as a party hereto.

 

    	 	-77-	 

     

    

 

(f)          Electronic
Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like
import in any Assignment and Assumption shall be deemed to include electronic signatures or the keeping of records in electronic
form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of
a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the
Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act or
any other similar state laws based on the Uniform Electronic Transactions Act.

 

Section 10.10.         Amendments.
 Any provision of this Agreement or the other Loan Documents may be amended or waived if, but only if, such amendment or waiver
is in writing and is signed by (a) the Borrower, (b) the Required Lenders (or the Agent with the consent of the Required Lenders),

with the waiver of acceptability of any post-default increase in interest rates (which waiver shall be effective with the consent
of the Required Lenders)) or of any fee payable hereunder without the consent of the Lender to which such payment is owing or which
has committed to make such Loan (or participate therein) hereunder or (B) change the application of payments set forth in
Section 2.9 without the consent of any Lender adversely affected thereby;

 

(ii)         no
amendment or waiver pursuant to this Section 10.10 shall, unless signed by each Lender, change the definition of Required
Lenders, change the provisions of this Section 10.10, release any material Guarantor (except as otherwise provided for in the Loan
Documents), affect the number of Lenders required to take any action hereunder or under any other Loan Document, or change or waive
any provision of any Loan Document that provides for the pro rata nature of disbursements or payments to Lenders; and

 

(iii)        in
addition to the other requirements of this Section 10.10, no amendment to Section 11 shall be made without the consent of the Guarantor(s)
affected thereby.

 

Notwithstanding anything to the contrary
herein, any provision of this Agreement may be amended by an agreement in writing entered into by the Borrower, the Required Lenders
and the Agent if, at the time such amendment becomes effective, each Lender not consenting thereto receives payment (including
pursuant to an assignment to a replacement Lender in accordance with the terms herein) in full of the principal of and interest
accrued on each Loan made by it and all other Obligations owing to it or accrued for its account under this Agreement,.

any of the foregoing Persons (each such Person being called an “Indemnitee”) against, and hold each Indemnitee
harmless from, any and all Damages (including the fees, charges and disbursements of any counsel for any Indemnitee), incurred
by any Indemnitee or asserted against any Indemnitee by any Person (including the Borrower or any Guarantor) other than such Indemnitee

that such indemnity shall not, as to any Indemnitee, be available to the extent that such losses, claims, damages, liabilities
or related expenses (x) are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted
from the gross negligence or willful misconduct of such Indemnitee, or (y) result from a claim brought by the Borrower or

at any time and from time to time, to the fullest extent permitted by applicable law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final, in whatever currency) at any time held, and other obligations (in whatever
currency) at any time owing, by such Lender or any such Affiliate, to or for the credit or the account of any Loan Party against
any and all of the obligations of such Loan Party now or hereafter existing under this Agreement or any other Loan Document to
such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any demand under this Agreement
or any other Loan Document and although such obligations of such Loan Party may be contingent or unmatured or are owed to a branch,
office or Affiliate of such Lender different from the branch, office or Affiliate holding such deposit or obligated on such Indebtedness.

and thereby shall be governed by, and construed in accordance with, the law of the state of New York, without regard to conflicts
of law provisions (other than sections 5-1401 and 5-1402 of the New York General Obligations Law).

 

(b)          Jurisdiction.
Each Loan Party irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind
or description, whether in law or equity, whether in contract or in tort or otherwise, against the Agent, any Lender, or any Related

thereto, in each case in any forum other than the courts of the State of New York sitting in New York County, and
of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of
the parties hereto irrevocably and unconditionally submits to the non-exclusive jurisdiction of such courts and agrees that
all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court
or, to the fullest extent permitted by applicable law, in such federal court. Each of the parties hereto agrees that a final judgment
in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment
or in any other manner provided by applicable Legal Requirements. Nothing in this Agreement or in any other Loan Document shall
affect any right that the Agent or any Lender may otherwise have to bring any action or proceeding relating to this Agreement or
any other Loan Document against any Loan Party or its properties in the courts of any jurisdiction.

 

(c)          Waiver
of Venue. Each Loan Party irrevocably and unconditionally waives, to the fullest extent permitted by applicable Legal Requirements,
any objection that it may now or hereafter have to the laying of venue of any action or proceeding arising out of or relating to

Legal Requirements.

 

Section 10.15.         Severability
of Provisions Any provision of any Loan Document which is unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such unenforceability without invalidating the remaining provisions hereof or affecting the validity
or enforceability of such provision in any other jurisdiction. All rights, remedies and powers provided in this Agreement and the
other Loan Documents may be exercised only to the extent that the exercise thereof does not violate any applicable mandatory provisions
of law, and all the provisions of this Agreement and other Loan Documents are intended to be subject to all applicable mandatory
provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Agreement
or the other Loan Documents invalid or unenforceable.

Section 10.16.         Excess
Interest. Notwithstanding any provision to the contrary contained herein or in any other Loan Document, no such provision shall
require the payment or permit the collection of any amount of interest in excess of the maximum amount of interest permitted by
applicable law to be charged for the use or detention, or the forbearance in the collection, of all or any portion of the Loans

pay any Excess Interest, (c) any Excess Interest that the Agent or any Lender may have received hereunder shall, at the option
of the Agent, be (i) applied as a credit against the then outstanding principal amount of Obligations hereunder and accrued
and unpaid interest thereon (not to exceed the maximum amount permitted by applicable law), (ii) refunded to the Borrower,
or (iii) any combination of the foregoing, (d) the interest rate payable hereunder or under any other Loan Document shall
be automatically subject to reduction to the maximum lawful contract rate allowed under applicable usury laws (the “Maximum
Rate”), and this Agreement and the other Loan Documents shall be deemed to have been, and shall be, reformed and modified
to reflect such reduction in the relevant interest rate, and (e) No Loan Party nor any endorser shall have any action against
the Agent or any Lender for any Damages whatsoever arising out of the payment or collection of any Excess Interest. Notwithstanding
the foregoing, if for any period of time interest on any of Borrower’s Obligations is calculated at the Maximum Rate rather
than the applicable rate under this Agreement, and thereafter such applicable rate becomes less than the Maximum Rate, the rate
of interest payable on the Borrower’s Obligations shall remain at the Maximum Rate until the Lenders have received the amount
of interest which such Lenders would have received during such period on the Borrower’s Obligations had the rate of interest
not been limited to the Maximum Rate during such period.

 

Section 10.17.         Construction.
The parties acknowledge and agree that the Loan Documents shall not be construed more favorably in favor of any party hereto based
upon which party drafted the same, it being acknowledged that all parties hereto contributed substantially to the negotiation of

or indirectly arising out of or relating to this Agreement or any other Loan Document or the transactions contemplated hereby or
thereby (whether based on contract, tort or any other theory). Each party hereto (a) certifies that no representative, agent
or attorney of any other person has represented, expressly or otherwise, that such other person would not, in the event of litigation,
seek to enforce the foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter
into this Agreement and the other Loan Documents by, among other things, the mutual waivers and certifications in this section.

or thereunder, (f) subject to an agreement containing provisions substantially the same as those of this Section, to any assignee
of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations under this Agreement
provided that such assignee or Participant is subject to the provisions of this Section 10.21, (g) on a confidential
basis to (i) any rating agency in connection with rating the Loan Parties or the Loans or (ii) the CUSIP Service Bureau or any
similar agency in connection with the issuance and monitoring of CUSIP numbers with respect to the Loans, (h) with the consent
of the Borrower, or (i) to the extent such Information (A) becomes publicly available other than as a result of a breach
of this Section or (B) becomes available to the Agent, any Lender, or any of their respective Affiliates on a nonconfidential
basis from a source other than the Borrower. In addition, the Agent and the Lenders may disclose the existence of this Agreement
and information about this Agreement to market data collectors, similar service providers to the lending industry and service providers
to the Agent and the Lenders in connection with the administration of this Agreement and the other Loan Documents.

 

For purposes of this
Section, “Information” means all information received from any Loan Party relating to the Loan Parties or any
of their respective businesses, other than any such information that is available to the Agent or any Lender on a nonconfidential
basis prior to disclosure by any Loan Party or any of its Subsidiaries, provided that, in the case of information received
from any Loan Party or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery
as confidential. Any Person required to maintain the confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality
of such Information as such Person would accord to its own confidential information.

contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings,
oral or written, relating to the subject matter hereof. Except as provided in Section 3.1, this Agreement shall become effective

of the Borrower’s financial condition and operations, provided that access to confidential proprietary information and facilities
need not be provided. BDC Purchaser agrees that any confidential information provided to or learned by it in connection with providing
such managerial assistance shall be kept in confidence in keeping with the confidentiality provisions set forth herein.

the Borrower by reason of the Loans and for other good and valuable consideration, receipt of which is hereby acknowledged, the
Parent and each Subsidiary party hereto (including any Subsidiary executing an Additional Guarantor Supplement substantially
in the form attached hereto as Exhibit G or such other form reasonably acceptable to the Agent) and the Borrower (as to the
Guaranteed Obligations of another Loan Party) hereby unconditionally and irrevocably guarantees jointly and severally to the Agent
and the Lenders the due and punctual payment of all present and future Obligations, including, but not limited to, the due and
punctual payment of principal of and interest on the Loans and the due and punctual payment of all other Obligations now or hereafter
owed by the Borrower under the Loan Documents, in each case as and when the same shall become due and payable, whether at stated
maturity, by acceleration, or otherwise, according to the terms hereof and thereof (including all interest, costs, fees, and charges
after the entry of an order for relief against the Borrower or such other obligor in a case under the United States Bankruptcy
Code or any similar proceeding, whether or not such interest, costs, fees and charges would be an allowed claim against the Borrower
or any such obligor in any such proceeding). In case of failure by the Borrower or other obligor punctually to pay any Guaranteed
Obligations guaranteed hereby, each Guarantor hereby unconditionally, jointly and severally agrees to make such payment or to cause
such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration,
or otherwise, and as if such payment were made by the Borrower or such obligor.

 

Section 11.2.          Guarantee
Unconditional. The obligations of each Guarantor under this Section 11 shall be unconditional and absolute and, without
limiting the generality of the foregoing, shall not be released, discharged, or otherwise affected by:

 

(a)          any
extension, renewal, settlement, compromise, waiver, or release in respect of any obligation of any Loan Party or other obligor
or of any other guarantor under this Agreement or any other Loan Document or by operation of law or otherwise;

 

(b)          any
modification or amendment of or supplement to this Agreement or any other Loan Document;

 

(c)          any
change in the corporate existence, structure, or ownership of, or any proceeding under any Debtor Relief Law affecting, the Borrower
or other obligor, any other guarantor, or any of their respective assets, or any resulting release or discharge of any obligation
of any Loan Party or other obligor or of any other guarantor contained in any Loan Document;

 

(d)          the
existence of any claim, set-off, or other rights which any Loan Party or other obligor or any other guarantor may have at any time
against the Agent, any Lender or any other Person, whether or not arising in connection herewith;

 

    	 	-85-	 

     

    

 

(e)          any
failure to assert, or any assertion of, any claim or demand or any exercise of, or failure to exercise, any rights or remedies
against any Loan Party or other obligor, any other guarantor, or any other Person or Property;

 

(f)          any
application of any sums by rights of set-off, counterclaim, or similar rights to any obligation of any Loan Party or other obligor,
regardless of what obligations of any Loan Party or other obligor remain unpaid, including the Guaranteed Obligations;

 

(g)          any
invalidity or unenforceability relating to or against any Loan Party or other obligor or any other guarantor for any reason of
this Agreement or of any other Loan Document or any provision of applicable law or regulation purporting to prohibit the payment
by any Loan Party or other obligor or any other guarantor of the principal of or interest on any Loan or any other amount payable
under the Loan Documents; or

 

(h)          any
other act or omission to act or delay of any kind by the Agent, any Lender or any other Person or any other circumstance whatsoever
that might, but for the provisions of this clause (h), constitute a legal or equitable discharge of the obligations of any Guarantor
under this Section 11.

 

Section 11.3.          Discharge
Only upon Termination Date; Reinstatement in Certain Circumstances. Each Guarantor’s obligations under this Section 11
shall remain in full force and effect until the Termination Date. If at any time any payment of the principal of or interest on
any Loan or any other amount payable by any Loan Party or other obligor or any Guarantor under the Loan Documents is rescinded
or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of such Loan Party or other obligor
or of any guarantor, or otherwise, each Guarantor’s obligations under this Section 11 with respect to such payment shall
be reinstated at such time as though such payment had become due but had not been made at such time.

 

Section 11.4.          Subrogation.
Each Guarantor agrees it will not exercise any rights which it may acquire by way of subrogation, reimbursement or indemnification
by any payment made hereunder, or otherwise, until all the Guaranteed Obligations (other than any contingent or indemnification
obligations not then due) shall have been paid in full or collateralized in a manner reasonably acceptable to the Lender or Affiliate
of a Lender to whom such obligations are owed. If any amount shall be paid to a Guarantor on account of such subrogation, reimbursement
or indemnification rights at any time prior to the Termination Date, such amount shall be held in trust for the benefit of the
Agent and the Lenders (and their Affiliates) and shall forthwith be paid to the Agent for the benefit of the Lenders (and their
Affiliates) or be credited and applied upon the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms
of this Agreement.

 

Section 11.5.          Subordination.
Each Guarantor hereby subordinates the payment of all indebtedness, obligations, and liabilities of the Borrower or any other Loan
Party owing to such Guarantor, whether now existing or hereafter arising, to the indefeasible payment in full in cash of all Guaranteed
Obligations (other than any contingent obligations not due and owing). During the existence of any Event of Default, subject to
Section 11.4 above, any such indebtedness, obligation, or liability of the Borrower or any other Loan Party owing to such
Guarantor shall be enforced and performance received by such Guarantor as trustee for the benefit of the holders of the Guaranteed
Obligations and the proceeds thereof shall be paid over to the Agent for application to the Guaranteed Obligations (whether
or not then due), but without reducing or affecting in any manner the liability of such Guarantor under this Section 11.

 

    	 	-86-	 

     

    

 

Section 11.6.          Waivers.
Each Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, and any notice not provided for herein, as well
as any requirement that at any time any action be taken by the Agent, any Lender, or any other Person against the Borrower or any
other Loan Party or other obligor, another guarantor, or any other Person.

 

Section 11.7.          Limit
on Recovery. Notwithstanding any other provision hereof, the right of recovery against each Guarantor under this Section 11
shall not exceed $1.00 less than the lowest amount which would render such Guarantor’s obligations under this Section 11
void or voidable under applicable law, including fraudulent conveyance law.

 

Section 11.8.          Stay
of Acceleration. If acceleration of the time for payment of any amount payable by the Borrower or other Loan Party or other
obligor under this Agreement or any other Loan Document is stayed upon the insolvency, bankruptcy or reorganization of the Borrower
or such other Loan Party or obligor, all such amounts otherwise subject to acceleration under the terms of this Agreement or the
other Loan Documents shall nonetheless be payable by the Guarantors hereunder forthwith on demand by the Agent made at the request
or otherwise with the consent of the Required Lenders.

 

Section 11.9.          Benefit
to Guarantors. The Loan Parties are engaged in related businesses and integrated to such an extent that the financial strength
and flexibility of the Borrower and the other Loan Parties has a direct impact on the success of each Guarantor. Each Guarantor
will derive substantial direct and indirect benefit from the extensions of credit hereunder, and each Guarantor acknowledges that
this guarantee is necessary or convenient to the conduct, promotion and attainment of its business.

 

Section 11.10.         [Reserved].

 

Section 11.11.         Guarantor
Covenants. Each Guarantor shall take such action as the Borrower is required by this Agreement to cause such Guarantor to take,
and shall refrain from taking such action as the Borrower is required by this Agreement to prohibit such Guarantor from taking.

Schedule 5.5

 

Litigation and Other Controversies

 

		1.	Pennsylvania Department of General Services Project (SCI Fayette): This lawsuit was filed
by the Commonwealth of Pennsylvania (the “Commonwealth”) against Limbach Facility Services LLC (“LFS”)
for a construction project completed in the fall of 2002. LFS contracted with the Pennsylvania Department of General Services (“DGS”)
in 2001, to perform mechanical construction work at the State Correctional Institution in Fayette County, PA. In 2007, DGS discovered
leaks in the underground thermal pipe system supplied by LFS’ subcontractor, Thermacor Process LP (“Thermacor”);
however, LFS believes that it is not responsible for the leaks. DGS did not pursue the matter further until it filed and served
a complaint against LFS in September 2012, seeking in excess of $8,000,000 in damages. In late December 2012, LFS filed an answer
to the complaint and joined Thermacor, Allegheny Group (Thermacor’s distributor) and the project engineer of record, L. Robert
Kimball and Associates, as defendants. Significant discovery has occurred during the ensuing three years. LFS submitted defense
of the suit to Arch Insurance and Travelers Insurance, and coverage was accepted under a reservation of rights by Travelers Insurance.
Trial is not anticipated until 2017, and the parties hope to submit to mediation in the fall of 2016.

 

		2.	Wilshire Vermont Apartments Project: This matter relates to LFS’ work as a subcontractor
to Taisei Construction for the Wilshire Vermont apartments project in 2004. On April 18, 2013, LFS was sued by the project owner
(the “Owner”) for alleged construction defects as part of a larger claim against the general contractor, the
design team and almost all subcontractors. LFS submitted defense of the suit to Arch Insurance and coverage was accepted under
a reservation of rights. The Owner alleges three defects in LFS’ work, seeking damages of approximately $900,000, with the
total suit claiming damages in of the approximate amount of $70,000,000. LFS has asserted defenses to each item, including that
liability may rest with a subcontractor or supplier that LFS has brought into the case. LFS’ expert also believes the total
value of the three items claimed by the Owner to be far less than claimed. All parties participated in mediation over three days,
commencing on July 27, 2015; however, no settlement was reached. LFS is working with the mediator to set up a meeting between the
Owner and LFS’ experts aimed at narrowing the issues and agreeing on the costs of repair, in hopes of allowing a settlement
to be reached when mediation resumes in 2016.

by virtue of ceasing to employ teamsters in the Company’s Michigan branch (the “Central States Pension Fund Matter”).
CSPF assessed the amount of withdrawal liability to be $613,485. LFS disputed the amount of the assessment and filed arbitration
against CSPF on May 14, 2015. A settlement was reached in December 2015, and the parties entered into that certain Settlement Agreement
and Release, dated March 31, 2016, between Central States, Southeast and Southwest Areas Pension Fund and Limbach Company LLC.
