This Limited, Conditional,
and Temporary Waiver and Agreement Regarding Loan Documents (herein, this “Agreement”) is entered into as of
November 19, 2018, by and among LIMBACH FACILITY SERVICES LLC, a Delaware limited liability company (the “Borrower”),
LIMBACH HOLDINGS LLC, a Delaware limited liability company (the “Parent”), the other Guarantors party hereto,
the Lenders party hereto, and FIFTH THIRD BANK, an Ohio banking corporation, as Administrative Agent (the “Administrative
Agent”) and L/C Issuer.


 


RECITALS:


 


A.           The
Borrower, the Parent, the other Guarantors party thereto, the Lenders party thereto, and Fifth Third Bank, as Administrative Agent
and L/C Issuer, are party to a Credit Agreement dated as of July 20, 2016 (as amended, modified, restated, or supplemented from
time to time, the “Credit Agreement”).


 


B.           The
Borrower has informed the Administrative Agent and the Lenders of Events of Default that occurred on September 30, 2018, under
the terms of the Credit Agreement and continue to exist as of the date hereof, which Events of Default are listed on Schedule 1
to this Agreement (each such instance of noncompliance being hereinafter referred to as an “Existing Default”
and, collectively, the “Existing Defaults”).


 


C.           The
Borrower has requested that the Administrative Agent, the L/C Issuer, and the Lenders during the Temporary Waiver Period to provide
a limited, conditional, and temporary waiver with respect to the Existing Defaults.


 


D.           Subject
to the terms and conditions set forth herein, during and only during the Temporary Waiver Period, the Administrative Agent, and
the Lenders are willing to provide a limited, conditional, and temporary waiver with respect to the Existing Defaults.


 


NOW, THEREFORE, for
good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:


 


Section
1.          Incorporation of Recitals; Defined Terms. The Borrower
acknowledges that the Recitals set forth above are true and correct. This Agreement shall constitute a Loan Document, and the Recitals
shall be construed as part of this Agreement. Each capitalized term used but not otherwise defined herein, including capitalized
terms used in the introductory paragraph hereof and the Recitals, has the meaning assigned to it in the Credit Agreement. Without
limiting the foregoing, “Temporary Waiver Effective Date” has the following definition:


 


“Temporary Waiver Effective Date”
means November 19, 2018.


 




     


     


    

 


Section
2.          Amounts Owing. The Borrower acknowledges and agrees
that as of November 15, 2018, the principal amount of Loans and Letters of Credit is $40,148,000.00 ($15,235,000.00 in Term Loans,
$13,512,000.00 in Revolving Loans, $7,986,000.00 in Bridge Term Loans, and $3,415,000.00 in Letters of Credit), and such amount
(together with interest and fees thereon) is justly and truly owing by the Borrower without defense, offset or counterclaim.


 


Section
3.          Acknowledgment of Defaults. The Borrower hereby acknowledges
and agrees that the Existing Defaults have occurred, constitute Events of Default, and, as a result of the Existing Defaults, as
well as any other Defaults or Events of Default that may exist, but subject to Section 4 hereof, the Administrative Agent and the
Lenders are entitled to exercise any and all default-related rights and remedies under the Credit Agreement, the other Loan Documents
and/or applicable law, including making a determination not to make further Loans or incur further L/C Obligations, to terminate
the Commitments, to accelerate the Obligations, to exercise rights against Collateral, to enforce Liens granted under the Collateral
Documents, or to exercise any other rights or remedies that may be available under the Loan Documents or under applicable law.


 


Section
4.          Limited, Conditional and Temporary Waiver. (a)
Upon satisfaction of the conditions precedent set forth in Section 8 below and subject to the terms and other conditions hereof,
the Administrative Agent and the Lenders grant during the Temporary Waiver Period a limited, conditional and temporary waiver of
the Existing Defaults; provided, that the foregoing limited, conditional and temporary waiver shall become null and void
and no further force and effect upon the termination of the Temporary Waiver Period. The Loan Parties acknowledge and agree that
the waiver under this Section 4 shall be limited specifically as written in this Section 4, is not a permanent waiver, is a one-time
waiver, and shall neither be deemed to be a waiver or modification of any other term, provision or condition of the Credit Agreement
or any other Loan Document nor a waiver of any Defaults or Events of Default other than the limited, conditional and temporary
waiver of the Existing Defaults solely as provided herein. Without limiting the foregoing, this Agreement shall not constitute
a consent to any transactions prohibited by the Credit Agreement or any other Loan Document. The Loan Parties further acknowledge
that, in granting the waiver under this Section 4, the Administrative Agent and the Lenders in entering into this Agreement and
maintaining credit outstanding to the Borrower during the Temporary Waiver Period are relying on the assurances provided by the
Loan Parties herein.


 


(b)          As
used herein, the term “Temporary Waiver Period” shall mean the period commencing on the Temporary Waiver Effective
Date and ending on the earliest to occur of (i) November 30, 2018 (5:00 p.m. Eastern Standard Time) (the “Temporary Waiver
Termination Date”) or (ii) the occurrence of any one or more of the following events: (A) the occurrence of any Default
or Event of Default under the Credit Agreement, other than the Existing Defaults; (B) any failure by the Borrower or any Guarantor
for any reason to comply with any term, condition, or provision contained in this Agreement (unless waived in writing by Administrative
Agent and the Lenders); (C) any representation made by the Borrower or any Guarantor in this Agreement or pursuant to it is incorrect
or misleading in any material respect when made; (D) any Material Adverse Effect shall occur as determined in good faith by the
Administrative Agent or the Required Lenders; and (E) any act of fraud, intentional misrepresentation, criminal misconduct, or
gross negligence by the Borrower or any Guarantor. The occurrence of any of the events set forth in the foregoing clauses (A) through
(E) shall constitute an immediate Event of Default under the Credit Agreement and, in such event, the Temporary Waiver Period is
automatically terminated and the Administrative Agent and the Lenders are then permitted and entitled under Section 7 of the Credit
Agreement to, among other things, decline to provide additional credit to the Borrower, permanently terminate the Commitments,
accelerate the Obligations, require cash collateral for outstanding Letters of Credit, and exercise any other rights and remedies
that may be available under the Loan Documents or applicable law.

(c)          Automatically
and without any notice or action by either the Administrative Agent or the Lenders with respect to any termination of the Temporary
Waiver Period, upon any such termination, the Administrative Agent and the Lenders shall be entitled (but not required) to exercise
any of the rights and remedies with respect to the Existing Defaults (or otherwise) available to them under the Loan Documents
or applicable law.


 


(d)          Without
limiting the generality of the foregoing, the Loan Parties acknowledge and agree that immediately upon expiration of the Temporary
Waiver Period, the Administrative Agent and the Lenders have all of their rights and remedies with respect to the Existing Defaults
to the same extent, and with the same force and effect, as if the limited, conditional and temporary waiver had not occurred. The
Loan Parties will not assert and hereby forever waive any right to assert that the Administrative Agent or the Lenders are obligated
in any way to forbear from enforcing their rights or remedies beyond the Temporary Waiver Period or that the Administrative Agent
and the Lenders are not entitled to act on the Existing Defaults after the termination of the Temporary Waiver Period as if such
defaults had just occurred and the Temporary Waiver Period had never existed. The Loan Parties acknowledge that the Lenders have
made no representations as to what actions, if any, the Lenders will take after the Temporary Waiver Period terminates, and the
Lenders and the Administrative Agent reserve any and all rights, remedies, and claims they have (after giving effect hereto) with
respect to the Existing Defaults and each other Default or Event of Default that may exist or may occur.


 


Section
5.          Extensions of Credit. During the Temporary Waiver Period
and subject to the terms hereof, the Lenders shall continue to make additional Revolving Loans available to the Borrower in accordance
with Section 2 of the Credit Agreement. Any request for credit under the Revolving Credit remains subject to the satisfaction of
the conditions precedent set forth in Section 3.1 of the Credit Agreement, except to the extent non-compliance with the conditions
set forth therein relate solely to the Existing Defaults.


 


Section
6.          Principal, Interest, Fee Payments, and Default Rate. The
Borrower shall continue to pay all principal on the Loans and Reimbursement Obligations on the Letters of Credit when due, including
all scheduled payments of principal on the Term Loans and the Bridge Term Loans, and the Borrower will continue to pay all interest
and fees on the Loans and Letters of Credit when due. Without limiting any of the rights available to the Administrative Agent
and the Lenders under Section 2.4(c) of the Credit Agreement, the Loan Parties acknowledge and agree that on and after the termination
date of the Temporary Waiver Period, unless the Amendment Agreement (as defined below) is executed and delivered by all parties
thereto so long as any Existing Default continues, the interest rates, fees and other amounts payable on Loans, Reimbursement Obligations,
L/C Participation Fees and other Obligations shall increase by 2.00% per annum in accordance with the terms of such Section 2.4(c)

Section
7.          Additional Agreements. The Loan Parties acknowledge and
agree that during the Temporary Waiver Period they shall not incur any additional Indebtedness (other than advances of Revolving
Loans and in process vehicle leases) or make any Permitted Acquisitions, Restricted Payments (other than to another Loan Party),
Capital Expenditures (other than in process vehicle leases), or voluntary prepayment of any Indebtedness or any other obligation
or liability. Further, in order to induce the Administrative Agent and Lenders into this Agreement, the Loan Parties agree that
on or before the Temporary Waiver Termination Date they shall execute and deliver to the Lenders an agreement regarding the Loan
Documents, including amendments to the Credit Agreement (such agreement, including such amendments, the “Amendment Agreement”),
which Amendment Agreement shall be acceptable to the Lenders in form and substance and shall include, among other terms and conditions,
the following, which terms and conditions are not an exhaustive list of all terms and conditions to be included in the Amendment
Agreement:


 


(a)          Shortening
of Revolving Credit and Term Loan Maturities. The “Revolving Credit Termination Date” shall be March 31,
2020 or such earlier date on which the Revolving Credit Commitments are terminated in whole pursuant to Section 2.10, 7.2 or 7.3,
and Section 2.7(a) of the Credit Agreement shall be revised so that the final maturity date of the Term Loans shall be March 31,
2020. For purposes of clarity, the final maturity date of the Bridge Term Loans shall remain April 12, 2019.


 


(b)          Reduction
of Commitments and Termination of Card Agreement. On December 31, 2018, the Swing Line Sublimit shall be reduced to $0.00 and
the aggregate Revolving Credit Commitments of the Lenders shall be reduced to $22,500,000, and on January 31, 2019, the aggregate
Revolving Credit Commitments of the Lenders shall be further reduced to $20,000,000. On or before December 14, 2018, the Borrower
shall terminate any and all commercial card agreements with the Administrative Agent and shall pay in cash all liabilities and
obligations owing thereunder.


 


(c)          Bonded
Accounts to be Ineligible. All Accounts subject to any Liens or other encumbrances in favor of the Bonding Company under any
Bonding Agreements, pursuant to any Legal Requirements, including common law, or otherwise shall be expressly excluded from Eligible
Accounts (such excluded Accounts, “Bonded Accounts”).


 


(d)          Revised
Financial Covenants. Section 6.20(a)-(d) of the Credit Agreement shall be deleted and replaced in their entirety with the following
financial covenants:


 


(i)         Minimum
EBITDA. The EBITDA for the quarter ending December 31, 2018, of Limbach, Inc. and its Subsidiaries shall not be less than $6,500,000.
The EBITDA for such quarter shall be determined based on the financial results of Limbach, Inc. and its Subsidiaries for the financial
quarter then ending, and EBITDA shall not otherwise be modified, except to permit an add-back for the Limited Waiver Fee, as defined
below. The Loan Parties failure to achieve this minimum EBITDA shall constitute an Event of Default under Section 7.1(b) of the
Credit Agreement and, without limiting the foregoing and in addition to all other fees and amounts payable, the Borrower shall
pay an EBITDA covenant fee of $300,000 for such violation, which fee shall be immediately due and payable. All fees payable pursuant
to the Amendment Agreement as set forth in this Section 7 shall be payable to the Administrative Agent for the ratable benefit
of the Lenders and any payment of such fees shall not constitute any satisfaction or waiver of any Event of Default arising from
the corresponding violation.


 




    	 	- 4 -	 



     


    

 


(ii)        Fixed
Charge Coverage Ratio. The “Fixed Charge Coverage Ratio” shall first be tested as of the last day of the
fiscal quarter ending March 31, 2019 and for the initial test quarter and as of the last day of each subsequent fiscal quarter
shall not be less than 1.10:1.00. The “Fixed Charge Coverage Ratio” shall be modified so that for the fiscal
quarter of Limbach, Inc. ending on or about March 31, 2019, the EBITDA, Capital Expenditures, and Fixed Charges shall be such amounts
for the two consecutive fiscal quarters then ending and for the fiscal quarter of Limbach, Inc. ending on or about June 30, 2019,
the EBITDA, Capital Expenditures, and Fixed Charges shall be such amounts for the three consecutive fiscal quarters then ending;
and thereafter shall be for the trailing four fiscal quarters of Limbach, Inc. Further, the principal amount of the Bridge Term
Loans payable on the maturity date therefore shall be excluded from Fixed Charges. The Loan Parties failure to achieve the required
Fixed Charge Coverage Ratio as of any such quarter end shall constitute an Event of Default under Section 7.1(b) of the Credit
Agreement and, without limiting the foregoing and in addition to all other fees and amounts payable, the Borrower shall pay a Fixed
Charge Coverage Ratio covenant fee of $300,000 for each such violation, which fee shall be immediately due and payable.


 


(iii)       Unfinanced
Capital Expenditures. The unfinanced Capital Expenditures of the Loan Parties during fiscal year 2019 shall be limited to $3,000,000;
provided that, the vehicle leases shall be excluded from this limit; provided however that, no unfinanced Capital
Expenditures, including for vehicle leases, shall be permitted on and after any quarter end date on which the Loan Parties fail
to achieve the required Fixed Charge Coverage Ratio for such date.


 


(e)          Refinancing
Efforts. The Loan Parties shall actively solicit proposals from other lenders to refinance all of the Obligations, and the
Loan Parties shall promptly advise the Administrative Agent of all refinancing proposals they receive. Without limiting the foregoing,
(i) on or before February 15, 2019, the Loan Parties shall deliver to the Administrative Agent and the Lenders one or more term

the Loan Parties shall deliver to the Administrative Agent and the Lenders at least one fully-executed commitment letter that will
provide a full payment in cash of all Obligations on or before April 12, 2019; and (iii) on or before April 12, 2019, the Obligations
shall be paid in full in cash with the proceeds of refinancing credit facilities. In the event the Loan Parties fail to deliver
the required term sheet within the time period required in accordance with the foregoing clause (e)(i), the Borrower shall pay
a fee of $250,000, which fee shall be immediately due and payable. In the event the Loan Parties fail to deliver the required commitment
letter within the time period required in accordance with the foregoing clause (e)(ii), the Borrower shall pay a fee of $250,000,
which fee shall be immediately due and payable. In the event the Loan Parties fail to pay the Obligations in full in cash within
the time period required in accordance with the foregoing clause (e)(iii), the Borrower shall pay a fee of $500,000, which fee

following 13-week period, together with a reconciliation of actual cash receipts and cash disbursements from the prior week against

or by equitable principles relating to enforceability. Each Loan Party acknowledges and agrees that nothing in the Credit Agreement,
this Agreement or any other Loan Document shall be deemed to require the consent of any Guarantor to any future waivers to the

Party (collectively, the “Releasing Parties”) hereby absolutely and unconditionally releases and forever discharges

from any and all claims, demands or causes of action of any kind, nature or description relating to or arising out of or in connection
with or as a result of any of the Obligations, the Credit Agreement, and any other Loan Documents, whether arising in law or equity
or upon contract or tort or under any state or federal law or otherwise, which each Releasing Party has had, now has or has made
claim to have against any such person for or by reason of any act, omission, matter, cause or thing whatsoever arising from the
beginning of time to and including the date of this Agreement, whether such claims, demands and causes of action are matured or
unmatured or known or unknown, other than, in each instance, as determined by a court of competent jurisdiction by final and non-appealable
judgment to have resulted from the gross negligence or willful misconduct of such Released Party. Each Releasing Party acknowledges
that it may hereafter discover facts different from or in addition to those now known or believed to be true with respect to such

any such differences or additional facts. Each Releasing Party understands, acknowledges and agrees that the release set forth
above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other
proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release. The Borrower hereby confirms
that the foregoing waiver and release is an informed waiver and release and is being freely given.


 


(b)          Each
Releasing Party, on behalf of itself and its successors, assigns, and other legal representatives, hereby absolutely, unconditionally
and irrevocably, covenants and agrees with and in favor of each Released Party above that it will not sue (at law, in equity, in
any regulatory proceeding or otherwise) any Released Party on the basis of any claim released, remised and discharged by such Releasing
Party pursuant to the above release. If any Releasing Party or any of its successors, assigns or other legal representations violates

in addition to such other damages as any Released Party may sustain as a result of such violation, all reasonable attorneys’
fees and costs incurred by such Released Party as a result of such violation; provided that, this sentence shall not apply
