    DIRECTOR
INDEMNIFICATION AGREEMENT

    

              THIS AGREEMENT is entered
into, effective as of May 28, 2010, between Roomlinx, Inc., a Nevada corporation
(the “Company”) and ________ (“Indemnitee”).

    

              WHEREAS, it is essential to
the Company to retain and attract as directors the most capable persons
available;

    

              WHEREAS, Indemnitee is a
director of the Company;

    

              WHEREAS, both the Company and
Indemnitee recognize the increased risk of litigation and other claims currently
being asserted against directors of corporations; and

    

              WHEREAS, in recognition of
Indemnitee’s need for substantial protection against personal liability in order
to enhance Indemnitee’s continued and effective service to the Company, and in
order to induce Indemnitee to provide continued services to the Company as a
director, the Company wishes to provide in this Agreement for the
indemnification of and the advancing of expenses to Indemnitee to the fullest
extent (whether partial or complete) permitted by law and as set forth in this
Agreement and for the coverage of Indemnitee under the Company’s directors’ and
officers’ liability insurance policies.

    

              NOW, THEREFORE, in
consideration of the above premises and of Indemnitee’s continuing to serve as a

agree as follows:

              (c)
Disinterested
Director: A director of the Company who is not and was not a party to the
Proceeding in respect of which indemnification is sought by
Indemnitee.

    

              (d)
Expenses: Any
expense, including without limitation, attorneys’ fees, retainers, court costs,
transcript costs, fees and expenses of experts, including accountants and other
advisors, travel expenses, duplicating costs, postage, delivery service fees,
filing fees, and all other disbursements or expenses of the types typically paid
or incurred in connection with investigating, defending, being a witness in, or
participating (including on appeal), or preparing for any of the foregoing, in
any Proceeding relating to any Indemnifiable Event, and any expenses of
establishing a right to indemnification under any of Sections 2, 4 or 5 of
this Agreement, in each case, to the extent actually and reasonably
incurred.

    

              (e)
Indemnifiable
Costs: Any cost that is eligible for indemnification pursuant to
applicable law, including, without limitation, any and all Expenses, liability
or loss, judgments, fines and amounts paid in settlement and any interest,
assessments, or other charges imposed thereon, and any federal, state, local, or
foreign taxes imposed as a result of the actual or deemed receipt of any
payments under this Agreement.

    

              (f)
Indemnifiable
Event: Any event or occurrence that takes place either prior to or after
the execution of this Agreement, related to the fact that Indemnitee is or was a
director of the Company, or while a director is or was serving at the request of
the Company as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise or related to anything done or not done by
Indemnitee in any such capacity, whether or not the basis of the Proceeding is
alleged action in an official capacity as a director of the Company, or in any
other capacity, as described above.

    

              (g)
Independent
Counsel: means a law firm, or a member of a law firm, that is experienced
in matters of corporation law and neither presently is, nor in the past three
years has been, retained to represent: (i) the Company or any of its
subsidiaries or affiliates, (ii) the Indemnitee or (iii) any other
party to the Proceeding giving rise to a claim for indemnification or Expense
Advances hereunder, in any matter (other than with respect to matters relating
to indemnification and advancement of expenses). No law firm or lawyer shall
qualify to serve as Independent Counsel if that person would, under the
applicable standards of professional conduct then prevailing, have a conflict of
interest in representing either the Company or Indemnitee in an action to
determine Indemnitee’s rights under this Agreement. The Indemnitee shall select
a law firm or member of a law firm to serve as Independent Counsel, subject to
the consent of the Company, which consent shall not be unreasonably withheld.
Subject to the foregoing, any law firm or a member of a law firm in the Am Law
200 shall be presumed to qualify as Independent Counsel. In the event that the
Indemnitee and the Company are unable to agree upon the selection of the
Independent Counsel, the parties shall first try to settle the dispute by
mediation under the Commercial Mediation Rules of the American Arbitration
Association. Any dispute that cannot be resolved by mediation shall be finally
resolved by arbitration by the American Arbitration Association under its
Commercial Arbitration Rules. The fees for any such dispute resolution procedure
shall be borne by the Company.

    

              (h)
Proceeding: Any
threatened, pending, or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative that relates to an Indemnifiable
Event.

    

              (i)
Reviewing
Party: Reviewing Party shall have the meaning ascribed to such term in
Section 3.

     

    
                2.
Agreement
to Indemnify.

       

    

              (a)
General Agreement
regarding Indemnification. In the event Indemnitee was, is, or becomes a
party to or witness or other participant in, or is threatened to be made a party
to or witness or other participant in, a Proceeding by reason of (or arising in
part out of) an Indemnifiable Event, the Company shall indemnify Indemnitee from
and against Indemnifiable Costs, to the fullest extent permitted by applicable
law, as the same exists or may hereafter be amended or interpreted (but in the
case of any such amendment or interpretation, only to the extent that such
amendment or interpretation permits the Company to provide broader
indemnification rights than were permitted prior thereto); provided that the
Company’s commitment set forth in this Section 2(a) to indemnify the Indemnitee
shall be subject to the limitations and procedural requirements set forth in
this Agreement.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

              (b)
Partial
Indemnification. If Indemnitee is entitled under any provision of this
Agreement to indemnification by the Company for some or a portion of
Indemnifiable Costs, but not, however, for the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled.

    

              (c)
Advancement of
Expenses. If so requested by Indemnitee, the Company shall advance to
Indemnitee, to the fullest extent permitted by applicable law, any and all
Expenses incurred by Indemnitee (an “Expense Advance” or an “Advance”) within 10
calendar days after the receipt by the Company of a request from Indemnitee for
an Advance, whether prior to or after final disposition of any Proceeding.
Indemnitee shall, and hereby undertakes to, repay to the Company any funds
advanced to Indemnitee or paid on his or her behalf if it shall ultimately be
determined that Indemnitee is not entitled to indemnification. Indemnitee shall
make any such repayment promptly following written notice of any such
determination. Payment by the Company of Indemnitee’s expenses in connection
with any Proceeding in advance of the final disposition thereof shall not be
deemed an admission by the Company that it shall ultimately be determined that
Indemnitee is entitled to indemnification. Any request for an Expense Advance
shall be accompanied by an itemization of the Expenses for which advancement is
sought, and a reasonably detailed summary shall be provided if the Company so
requests. Advances shall be made without regard to Indemnitee’s ability to repay
the Expenses. If Indemnitee has commenced legal proceedings in a court of
competent jurisdiction in the State of Nevada to secure a determination that
Indemnitee should be indemnified under applicable law, as provided in
Section 4, any determination made by the Reviewing Party that Indemnitee
would not be permitted to be indemnified under applicable law shall not be
binding and Indemnitee shall not be required to reimburse the Company for any
Expense Advance until a final judicial determination is made with respect
thereto (as to which all rights of appeal therefrom have been exhausted or have
lapsed). Indemnitee’s obligation to reimburse the Company for Expense Advances
shall be unsecured and no interest shall be charged thereon.

    

              (d)
Exception to
Obligation to Indemnify and Advance Expenses. Notwithstanding anything in
this Agreement to the contrary, Indemnitee shall not be entitled to
indemnification or advancement pursuant to this Agreement in connection with any
Proceeding initiated by Indemnitee against the Company or any director or
officer of the Company unless (i) the Company has joined in or the Board
has consented to the initiation of such Proceeding; or (ii) the Proceeding
is one to enforce indemnification rights under this Agreement, including
Section 5.

     

    
                3.
Reviewing
Party.

    

    
    

    

              (a)
Definition of
Reviewing Party. Other than as contemplated by Section 3(b), the
person, persons or entity who shall determine whether Indemnitee is entitled to
indemnification in the first instance (“the Reviewing Party”) shall be
(i) the Board of Directors of the Company acting by a majority vote of a
quorum of Disinterested Directors or (ii) if there are no Disinterested
Directors, or if the Disinterested Directors so direct, by Independent Counsel
in a written determination to the Board of Directors, a copy of which shall be
delivered to Indemnitee.

    

              (b)
Reviewing Party
Following Change in Control. After a Change in Control, the Reviewing
Party shall be the Independent Counsel. With respect to all matters arising from
such a Change in Control concerning the rights of Indemnitee to indemnity
payments and Expense Advances under this Agreement or any other agreement or
under applicable law or the Company’s Articles of Incorporation or Bylaws now or
hereafter in effect relating to indemnification for Indemnifiable Events, the
Company shall seek legal advice only from the Independent Counsel. Such counsel,
among other things, shall render its written opinion to the Company and
Indemnitee as to whether and to what extent the Indemnitee should be permitted
to be indemnified under applicable law. The Company agrees to pay the reasonable
fees of the Independent Counsel and to indemnify fully such counsel against any
and all expenses (including attorneys’ fees), claims, liabilities, loss, and
damages arising out of or relating to this Agreement or the engagement of
Independent Counsel pursuant hereto.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

              4. Indemnification
Process and Appeal.

    

              (a)
Indemnification
Payment.

     

    
        (i)     
The
determination with respect to Indemnitee’s entitlement to indemnification shall,
to the extent practicable, be made by the Reviewing Party not later than 30
calendar days after receipt by the Company of a written demand on the Company
for indemnification (which written demand shall include such documentation and
information as is reasonably available to Indemnitee and is reasonably necessary
to determine whether and to what extent Indemnitee is entitled to
indemnification). The Reviewing Party making the determination with respect to
Indemnitee’s entitlement to indemnification shall notify Indemnitee of such
written determination no later than two business days
thereafter.

       (ii)     
Unless
the Reviewing Party has provided a written determination to the Company that
Indemnitee is not entitled to indemnification under applicable law, Indemnitee
shall be entitled to indemnification of Indemnifiable Costs, and shall receive
payment thereof, from the Company in accordance with this Agreement as early as
practicable, but not later than 10 business days after the Reviewing Party has
made its determination with respect to Indemnitee’s entitlement to
indemnification.

    

     

              (b)
Suit to Enforce
Rights. If (i) no determination of entitlement to indemnification
shall have been made within the time limitation for such a determination set
forth in Section 4(a)(i), (ii) payment of indemnification pursuant to
Section 4(a)(ii) is not made within the period permitted for such payment
by such section, (iii) the Reviewing Party determines pursuant to Section
4(a) that Indemnitee is not entitled to indemnification under this Agreement, or
(iv) Indemnitee has not received advancement of Expenses within the time period
permitted for such advancement by Section 2(c), then Indemnitee shall have
the right to enforce the indemnification rights granted under this Agreement by
commencing litigation in any court of competent jurisdiction in the State of
Nevada seeking an initial determination by the court or challenging any
determination by the Reviewing Party or any aspect thereof. The Company hereby
consents to service of process and to appear in any such proceeding. Any
determination by the Reviewing Party not challenged by the Indemnitee within six
months of the date of the Reviewing Party’s determination shall be binding on
the Company and Indemnitee. The remedy provided for in this Section 4 shall
be in addition to any other remedies available to Indemnitee in law or
equity.

     

    
                (c)
Defense to
Indemnification, Burden of Proof, and Presumptions.

       

      (i)       
To
the maximum extent permitted by applicable law in making a determination with
respect to entitlement to indemnification (or payment of Expense Advances)
hereunder, the Reviewing Party shall presume that an Indemnitee is entitled to
indemnification (or payment of Expense Advances) under this Agreement, and the
Company shall have the burden of proof to overcome that presumption in
connection with the making by the Reviewing Party of any determination contrary
to that presumption.

    

    
      (ii)       
It
shall be a defense to any action brought by Indemnitee against the Company to
enforce this Agreement that it is not permissible under applicable law for the
Company to indemnify Indemnitee for the amount claimed.

         
(iii)      For
purposes of this Agreement, the termination of any claim, action, suit, or
proceeding, by judgment, order, settlement (whether with or without court
approval), conviction, or upon a plea of nolo contendere, or its equivalent,
shall not create a presumption that Indemnitee did not meet any particular
standard of conduct or have any particular belief or that a court has determined
that indemnification is not permitted by applicable
law.

    

    

              5.
Indemnification
for Expenses Incurred in Enforcing Rights. The Company shall indemnify
Indemnitee against any and all Expenses to the fullest extent permitted by law
and, if requested by Indemnitee pursuant to the procedures set forth in
Section 2(c), shall advance such Expenses to Indemnitee, that are incurred
by Indemnitee in connection with any claim asserted against or action brought by
Indemnitee for:

    
       

       
(i) enforcement
of this Agreement;

    

    
    

    
      	
               
      

            	
              (ii)

            	
              indemnification
      of Indemnifiable Costs or Expense Advances by the Company under this
      Agreement or any other agreement or under applicable law or the Company’s
      Articles of Incorporation or Bylaws now or hereafter in effect relating to
      indemnification for Indemnifiable Events;
and/or

            

    

    
      	
               
      

            	
              (iii)

            	
              recovery
      under directors’ and officers’ liability insurance policies maintained by
      the Company.

            

    

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

    
 

              6. Notification
and Defense of Proceeding.

    

              (a)
Notice.
Promptly after receipt by Indemnitee of notice of the commencement of any
Proceeding, Indemnitee will, if a claim in respect thereof is to be made against
the Company under this Agreement, notify the Company of the commencement
thereof. The failure to notify or promptly notify the Company shall not relieve
the Company from any liability which it may have to the Indemnitee otherwise
than under this Agreement, and shall not relieve the Company from liability
hereunder except to the extent the Company has been materially prejudiced or as
further provided in Section 6(c).

    

              (b)
Defense. With
respect to any Proceeding as to which Indemnitee notifies the Company of the
commencement thereof, the Company will be entitled to participate in the
Proceeding at its own expense and except as otherwise provided below, to the
extent the Company so wishes, it may assume the defense thereof with counsel
selected by the Company and reasonably acceptable to Indemnitee. After notice
from the Company to Indemnitee of its election to assume the defense of any
Proceeding, the Company will not be liable to Indemnitee under this Agreement or
otherwise for any Expenses subsequently incurred by Indemnitee in connection
with the defense of such Proceeding other than reasonable costs of investigation
or as otherwise provided below. Indemnitee shall have the right to employ
separate counsel in such Proceeding, but all Expenses related thereto incurred
after notice from the Company of its assumption of the defense shall be at
Indemnitee’s expense unless: (i) the employment of counsel by Indemnitee
has been authorized by the Company, (ii) Indemnitee has reasonably
determined that there may be a conflict of interest between Indemnitee and the
Company in the defense of the Proceeding, (iii) after a Change in Control,
the employment of counsel by Indemnitee has been approved by the Independent
Counsel, or (iv) the Company shall not within 60 calendar days in fact have
employed counsel to assume the defense of such Proceeding, in each of which case
all Expenses of the Proceeding shall be borne by the Company. If the Company has
selected counsel to represent Indemnitee and other current and former directors,
officers or employees of the Company in the defense of a Proceeding, and a
majority of such persons, including Indemnitee, reasonably object to such
counsel selected by the Company pursuant to the first sentence of this Section 6(b),
then such persons, including Indemnitee, shall be permitted to employ one
additional counsel(s) and local counsel of their choice and the reasonable fees
and expenses of such counsel(s) shall be at the expense of the Company; provided, however, that such
counsel shall, if required by any company with which the Company obtains or
maintains insurance, be approved by such company or chosen from amongst the list
of counsel approved by such company. In the event separate counsel(s) is
retained by Indemnitee and/or by a group of persons including Indemnitee
pursuant to this Section 6(b), the Company shall cooperate with such
counsel(s) with respect to the defense of the Proceeding, including making
documents, witnesses and other information related to the defense available to
such separate counsel(s) pursuant to joint-defense agreements or confidentiality
agreements, as appropriate. The Company shall not be entitled to assume the
defense of any Proceeding (x) brought by or on behalf of the Company,
(y) as to which Indemnitee shall have made the determination provided for
in clause (ii) above or (z) as to which Independent Counsel has
approved the employment of counsel by Indemnitee in accordance with clause
(iii) above.

    

              (c)
Settlement of
Claims. The
Company shall not be liable to indemnify Indemnitee under this Agreement or
otherwise for any amounts paid in settlement of any Proceeding effected without
the Company’s written consent. The Company shall not settle any Proceeding in
any manner that would impose any monetary damages, penalty or limitation on
Indemnitee without Indemnitee’s prior written consent. Neither the Company nor
the Indemnitee will unreasonably withhold their consent to any proposed
settlement. The Company shall not be liable to indemnify the Indemnitee under
this Agreement with regard to any judicial award if the Company was not given a
reasonable and timely opportunity, at its expense, to participate in the defense
of such action; the Company’s liability hereunder shall not be excused if
participation in the Proceeding by the Company was barred by this
Agreement.

    

              7.
Non-Exclusivity. The rights of Indemnitee
hereunder shall be in addition to any other rights Indemnitee may have under the
laws of the State of Nevada, the Company’s Articles of Incorporation, Bylaws,
applicable law, or otherwise. To the extent that a change in applicable law
(whether by statute or judicial decision) permits greater indemnification by
agreement than would be afforded currently under the Company’s Articles of
Incorporation, Bylaws, applicable law, or this Agreement, it is the intent of
the parties that Indemnitee enjoy by this Agreement the greater benefits so
afforded by such change.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

              8.
Liability
Insurance. The
Company shall use its best efforts (a) to continue to maintain in effect
directors’ and officers’ insurance policies and fiduciary liability insurance
policies (collectively, “D&O Insurance Policies”) with terms, conditions,
retentions and limits of liability that are at least as favorable as those
contained in the Company’s D&O Insurance Policies in effect as of the date
hereof (D&O Insurance Policies containing such terms, conditions, retentions
and limits of liability, referred to herein as “Comparable D&O Insurance
Policies”), and, for so long as Indemnitee serves as a director of the Company
and for a period of six (6) years thereafter, to cause Indemnitee to be covered
under such Comparable D&O Insurance Policies in accordance with their
respective terms, and (b) for a period of not less than six (6) years
following the occurrence of (i) a Change in Control or (ii) the
Company ceasing to operate its business as a going concern, to maintain in
effect Comparable D&O Insurance Policies, and, until the earlier of
(x) such time as the Company is no longer required to maintain such
Comparable D&O Insurance Policies pursuant to this clause (b) or
(y) the sixth (6th)
anniversary of Indemnitee ceasing to serve as a director of the Company, to
cause Indemnitee to be covered under such Comparable D&O Insurance Policies
in accordance with their respective terms. In the event the Company, at any time
it is required to maintain Comparable D&O Insurance Policies pursuant to the

Effective on and after the Effective Date, the Existing Credit Agreement is amended and restated in its entirety by this Agreement, and

continuing Liens on all of the Loan Collateral, (ii) secure all of the Obligations, and (iii) represent valid, first priority and perfected Liens on all of the Loan Collateral except to the extent, if any, of any Permitted Liens.

 The existing Loan Documents, except as amended (or, as applicable, as amended and restated) by this Agreement or by a
separate agreement or instrument, shall remain in full force and effect, and each of them is hereby ratified and confirmed by Loan Parties and Lender. References in any of the Loan Documents to the Existing Credit Agreement shall, after the

Agreement and the other Loan Documents remain accrued and unpaid hereunder and under the other Loan Documents and do not constitute any part of the principal amount due hereunder.

 Section 2. Loans. 

2.1 Revolving Loans. (a) Subject to the terms and conditions hereof and in reliance upon the representations and warranties of
Borrowers herein, Lender hereby extends to Borrowers a line of credit facility (the “Line of Credit”) pursuant to which Lender will make loans to Borrowers on a revolving basis upon Borrowers’ request from time to time during
the term of this Agreement (the “Revolving Loans”) in an amount not exceeding, in the aggregate, the lesser of: (i) the Revolving Commitment or (ii) the Borrowing Base. Borrowers may borrow, repay, in whole or in
part, and reborrow under the Line of Credit; provided that if Revolving Loan Availability shall at any time be less than zero dollars (such condition being an “Overadvance”), Borrowers shall immediately, without demand or
notice, reduce the then outstanding balance of the Revolving Loans so that such Overadvance shall no longer exist. Lender may create and maintain Borrowing Base Reserves against the Borrowing Base. If, at any time, Lender implements a Borrowing Base
Reserve in excess of $100,000 (“Borrowing Base Reserve Implementation”), Lender will give Parent 5 Business Days advance written notice of such Borrowing Base Reserve Implementation unless an Event of Default then exists, in which
case Lender will give Parent contemporaneous oral or written notice of such Borrowing Base Reserve Implementation. 
 (b) On and
after the Effective Date, the Line of Credit may be used by Borrowers solely for general working capital and corporate purposes. 

(c) On the Signature Date, Borrowers shall execute and deliver to Lender a Sixth Amended and Restated Revolving Credit Promissory Note in
the form of Exhibit 2.1 to this Agreement (as amended, the “Revolving Note”), dated as of the Effective Date, in the principal amount of the Revolving Commitment, and bearing interest at such rates, and payable upon such
terms, as specified in the Revolving Note. 
 (d) The entire unpaid balance of the Line of Credit, plus all accrued and unpaid
interest, any other charges, advances and fees, if any, outstanding with respect to the Revolving Loans, the Letter of Credit Obligations, and all other Obligations related to the Revolving Loans and the Letter of Credit Obligations shall be due and
payable in full on the Termination Date with respect to the Line of Credit. Subject to the terms of the Revolving Note, Borrowers may prepay the Revolving Note in whole or part at any time. 

(e) The dilution percentage with respect to Eligible Accounts (i.e., reductions in the amount of Accounts because of returns,
discounts, price adjustments, credit memoranda, credits, contras, allowances and other offsets) may not increase above 5%. If the dilution percentage increases above 5%, then Lender will have the right, to be exercised in good faith, to decrease the
advance rate against Eligible Accounts during that time period that the dilution percentage is above 5%. If, at any time, Lender decreases the then stated advance rate against Eligible Accounts as a result of an increase in the dilution percentage
(“Dilution Advance Rate Decrease”), Lender will give Parent 5 Business Days advance written notice of such Dilution Advance Rate Decrease, unless an Event of Default then exists, in which case Lender will give Parent contemporaneous
oral or written notice of such Dilution Advance Rate Decrease. 
  

 -26- 

 (f) Anything to the contrary in this Agreement notwithstanding, only Borrowers may request

Parent Advances made during that calendar month, and (B) Borrowers have supporting documentation in existence at the time of the Parent Advances to effect the allocation referred to in the immediately preceding clause (A). If either of the
preceding conditions are not met, or if an Event of Default has occurred and is continuing, and without limiting any of the other rights or remedies of Lender as a result of such Event of Default, Parent may no longer request or receive any Parent
Advances; and 
 (ii) Parent may request and receive Revolving Loan advances to pay the direct out-of-pocket costs incurred by
Parent with respect to general and administrative expenses of Borrowers (“Overhead Expenses”) so long as (A) all Overhead Expenses are allocated to each Borrower by the last day of each calendar month with respect to Overhead
Expenses paid during that calendar month, (B) the aggregate amount of Revolving Loan advances made to pay Overhead Expenses in any month does not exceed a rate equal to two percent (2%) per annum of the aggregate revenue of Borrowers for
that month, and (C) no Event of Default has occurred and is continuing or is created thereby. 
 2.2 Term
Loans/Mandatory Prepayments. 
 (a) On December 29, 2005, Lender made a loan to the Existing Borrowers in an original
aggregate amount equal to $3,100,000 (“Term Loan A”). On February 28, 2007, Lender made a loan to the Existing Borrowers in an original aggregate amount equal to $5,000,000 (“Term Loan B”). The Existing

part of Term Loan C may, on the repayment thereof, be redrawn or reborrowed by a Borrower. The entire unpaid principal balance of, and accrued interest on, Term Loan C, if not sooner repaid, will be due and payable on the Termination Date with
respect to Term Loan C. On the Signature Date, Borrowers shall execute and deliver to Lender an Amended and Restated Term Promissory Note in the form of Exhibit 2.2 to this Agreement (as amended, “Term Loan Note C”), dated as
of the Effective Date, in the original principal amount of $1,978,466.70, and bearing interest at such rates, and payable upon such terms, as specified in Term Loan Note C. 

 

 -27- 

 (b) Subject to the terms of Term Loan Note C and this Agreement, Borrowers may prepay Term
Loan C in whole or part at any time. Any prepayment of Term Loan C will be applied to the last to mature of the payments required under Term Loan Note C. Except as provided in the preceding sentence, no partial prepayment will change the due dates
or the amount of the monthly principal payments otherwise required by Term Loan Note C. 
 (c) In addition to the scheduled
payments of principal on Term Loan C set forth in Term Loan Note C, the following payments shall be made to, or retained by, Lender and applied as provided in Section 2.2(d): 

(i) Within three Business Days after the date of receipt thereof by any Loan Party, an amount equal to 100% of the Net Proceeds from any
sale of any asset (exclusive of (A) sales of Inventory in the ordinary course of business or (B) sales or other dispositions of Equipment, the proceeds of which are used for the replacement of such Equipment as contemplated by
Section 5.7); 
 (ii) Within three Business Days after the date of receipt thereof by any Loan Party, 100% of the
Net Proceeds from any insurance or condemnation proceeds payable in respect of, or arising out of, any loss or damage to any of any Borrower’s properties (other than (A) dispositions of Equipment, which is the subject of an Event of Loss,
in connection with the replacement of such Equipment as contemplated by Section 5.7 or (B) repairs or replacements of any Mortgaged Property, which is the subject of an Event of Loss, to the extent set forth in the Mortgages); and

 (iii) On the date of receipt thereof by any Loan Party, an amount equal to 100% of the Net Proceeds payable or owing to any
Loan Party under, or arising out of, the Effox Acquisition Agreement, the Effox Acquisition, the FKI Acquisition Agreement or the FKI Acquisition, including any purchase price adjustment payment or indemnification or reimbursement payment made after
the Effective Date (as defined in the Third Amendment) with respect to the Effox Acquisition or the FKI Acquisition. Notwithstanding anything to the contrary in this clause (iii), if a Loan Party incurs any out-of-pocket cost or expense for
which it receives reimbursement from Effox under the Effox Acquisition Agreement (“Out-of-Pocket Effox Reimbursement”) or from FKI under the FKI Acquisition Agreement (“Out-of-Pocket FKI Reimbursement”), then the
Loan Parties will (A) apply such Out-of-Pocket Effox Reimbursement or Out-of-Pocket FKI Reimbursement, as applicable, against the then outstanding Revolving Loans and (B) not be obligated to apply such Out-of-Pocket Effox Reimbursement or
Out-of-Pocket FKI Reimbursement, as applicable, as a mandatory prepayment of Term Loan C. 
 (iv) Beginning on May 1, 2011
and continuing on the same date thereafter occurring in each subsequent Fiscal Year until the payment in full of Term Loan C, Borrowers will make a payment to Lender in an aggregate amount equal to 50% of Excess Cash Flow for the immediately
preceding Fiscal Year of Borrowers then ended (each, an “Excess Cash Flow Payment”); provided that Lender will not require an Excess Cash Flow Payment, in any Fiscal Year, in an aggregate amount greater than $500,000, but
Borrowers may make a voluntary prepayment of Term Loan C in excess of such $500,000. Each Excess Cash Flow Payment shall, absent the occurrence and continuance of an Event of Default, be applied to the remaining installments of principal under Term
Loan Note C, in the inverse order of maturity. 
  

 -28- 

 (d) With respect to mandatory prepayments described in Sections 2.2(c)(i) through
2.2(c)(iv), such prepayments shall, absent the occurrence and continuance of an Event of Default: (i) first, be applied to the remaining installments of principal under Term Loan C, in the inverse order of maturity, until Term
Loan C has been paid in full, (ii) second, at any time after Term Loan C shall have been repaid in full, such payments shall be applied to the outstanding balance of the Revolving Loans, (iii) third, after the Revolving Loans
have been paid in full, such payments shall be applied to cash collateralize outstanding Letter of Credit Obligations, and (iv) fourth, after all Letter of Credit Obligations are fully cash collateralized, in repayment of any of the
other Obligations then due and payable, and the Revolving Commitment will, at Lender’s sole option, be contemporaneously reduced by an amount deemed appropriate by Lender in the exercise of its discretion in good faith. Nothing in this
Section 2.2 shall be construed to constitute Lender’s consent to any transaction that is not permitted by other provisions of this Agreement or the other Loan Documents. No partial prepayment under Section 2.2(c) will
change the due dates or the amount of the monthly principal payments otherwise required by Term Loan Note C. 
 (e) Within three
Business Days after the date of receipt thereof by any Loan Party, the Loan Parties shall deliver to Lender: (i) 100% of the Net Proceeds payable under any Life Insurance, including any death benefit, (ii) an amount equal to 100% of:
(A) any Net Proceeds from the issuance by Parent of any Ownership Interests after the Effective Date or (B) any dividend or distribution to a Loan Party from a Person other than a Loan Party, or (iii) 100% of the Net Proceeds from any
Tax Refund. Such amounts shall, in each case, be applied by Lender to the Obligations as follows: (1) first, to the outstanding balance of the Revolving Loans, (2) second, after the Revolving Loans have been paid in full,
such payments shall be applied to cash collateralize outstanding Letter of Credit Obligations, and (3) third, after all Letter of Credit Obligations are fully cash collateralized, in repayment of any of the other Obligations (other than
Term Loan C absent the existence and continuation of an Event of Default) then due and payable, and the Revolving Commitment will, at Lender’s sole option, be contemporaneously reduced by an amount deemed appropriate by Lender in the exercise
of its discretion in good faith. 
 2.3 Letters of Credit. 

(a) Until the Termination Date with respect to the Line of Credit and subject to the other terms and conditions of this Agreement,
Borrowers may request Lender to issue one or more of its standard standby letters of credit (“Standby Letter of Credit”) in favor of such beneficiary(ies) as are designated by Borrowers by delivering to Lender: (i) a Letter of
Credit Application completed to the reasonable satisfaction of Lender, together with the proposed form of the Letter of Credit (which, in all respects, will comply with the applicable requirements of Section 2.3(b)), (ii) a
Borrowing Base Certificate which calculates the Letter of Credit Availability by giving effect to the proposed Letter of Credit, and (iii) such other Letter of Credit Documents that Lender then customarily requires in the issuance of letters of
credit. Lender, in addition to the other terms of this Agreement, will have no obligation to issue the proposed Letter of Credit if, after giving effect to the proposed Letter of Credit, there would exist a Letter of Credit Deficiency. The making of
each Letter of Credit request by Borrowers will be deemed to be a representation by Borrowers that the Letter of Credit may be issued in accordance with, and will not violate the terms of, this Section 2.3. 

 

 -29- 

 (b) Each Letter of Credit issued under this Agreement will, among other things, (i) be
in such form requested by Borrowers as is acceptable to Lender in its discretion exercised in good faith, (ii) be denominated in Dollars, and (iii) be issued to support Borrowers’ obligations that finance its business needs incurred

no obligation to issue any Letter of Credit with an expiry date later than the date that is 30 days prior to the stated Termination Date applicable to the Line of Credit. Each Letter of Credit Application and each Letter of Credit will set forth
which rules or customs apply to the Letter of Credit. Such rules and customs may include, but are not limited to, the International Standby Practices, as published by the International Chamber of Commerce (“ISP”) or the Uniform
Customs and Practice for Documentary Credits, as published by ISP. In any event, the Letter of Credit shall be governed by (A) the rules or customs set forth in the Letter of Credit and (B) the internal laws of the State of Ohio and the
United States of America, except to the extent such laws are inconsistent with the rules or customs adopted in the Letter of Credit Documents and Letter of Credit as set forth above. 

(c) Upon receipt of a request from Borrowers to open any Letter of Credit and of all attendant Letter of Credit Documents completed to
Lender’s reasonable satisfaction, Lender, within three (3) Business Days, may either (i) issue the requested Letter of Credit to the beneficiary thereof and transmit a copy to Borrowers, or (ii) elect, in its discretion exercised
in good faith, not to issue the proposed Letter of Credit. If Lender elects not to issue such Letter of Credit, Lender will communicate in writing to Borrowers the reason(s) why Lender has declined such request. 

(d) All Letter of Credit Obligations are payable on Lender’s demand or payable as otherwise set forth in the applicable Letter of
Credit Documents. Borrowers jointly and severally promise to pay Lender the amount of all other Letter of Credit Obligations immediately when due, irrespective of any claim, setoff, defense or other right which any Borrower may have at any time
against Lender or any other Person. Subject to the terms of Section 6.6, Borrowers hereby irrevocably instruct Lender, on the same Business Day that Lender is obligated to fund a drawing or make any expenditure or any other payment under
a Letter of Credit or incurs any cost or expense under any Letter of Credit, to reimburse Lender for any drawing, expenditure or other payment made, or cost or expense incurred, by Lender debiting any Borrower’s loan account(s) with Lender as
an advance of the Revolving Loans pursuant to Section 2.1. If the advance of a Revolving Loan to reimburse Lender for any drawing, expenditure or other payment made, or cost or expense incurred, by Lender in respect of any Letter of
Credit results (or to the extent that it results) in any Letter of Credit Deficiency, then Borrowers will immediately eliminate any Letter of Credit Deficiency in accordance with the terms of Section 2.1(a). 

 

 -30- 

 (e) All Letter of Credit Obligations will constitute part of the Obligations and be secured
by the Loan Collateral. 
 (f) In determining whether to pay under any Letter of Credit, Lender will be responsible only to
confirm in good faith that any documents required to have been delivered under a Letter of Credit appear to comply substantially on their face with the requirements of the Letter of Credit, and any action taken or omitted by Lender in good faith
under or in connection with any Letter of Credit will not subject Lender to any liability to any Borrower; provided, however, nothing in this Section 2.3(f) will relieve Lender of any liability it may have to Borrowers to the
extent, but only to the extent, of any direct, as opposed to consequential, damages suffered by Borrowers from Lender’s gross negligence or willful misconduct. Lender shall not be obligated to cause any Letter of Credit to be extended or
amended unless the requirements of this Section 2.3 are met as though a new Letter of Credit were being requested and issued. 

(g) In addition to amounts payable as elsewhere provided in this Section 2.3, Borrowers will protect, indemnify, pay and save
Lender harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys’ fees) which Lender (provided that it acts (or omits to act) in good faith and except for
Lender’s gross negligence or willful misconduct) may incur or be subject to as a consequence, direct or indirect, of the issuance of any Letter of Credit or the provision of any credit support or enhancement in connection therewith exclusive of
claims, demands, liabilities, damages, losses, costs, charges and expenses to the extent caused by the gross negligence or willful misconduct of Lender. The agreement in this Section 2.3(g) shall survive repayment of all other
Obligations. 
 (h) As between Borrowers and Lender, Borrowers assume all risks of the acts and omissions of, or misuse of any
of the Letters of Credit by, the respective beneficiaries of such Letters of Credit. In furtherance and not in limitation of the foregoing, Lender shall not be responsible for: (i) the existence of any claim, set-off, defense or other right
which any Borrower may have at any time against any beneficiary, or any transferee, of any Letter of Credit (or any Persons for whom any such beneficiary or any such transferee may be acting), Lender or any other Person, whether in connection with
this Agreement or the other Loan Documents, the transactions contemplated in this Agreement, or any unrelated transaction; (ii) any statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid
or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; (iii) any default, negligence, misfeasance, suspension, insolvency, or bankruptcy of any shipper or any other Person involved in any transaction
covered thereby or any correspondent or agent of Lender to whom any drafts, documents or instruments may be entrusted; (iv) any delay, interruption, omission or error in transmission or delivery of any document, certificate, draft, or message;
(v) payment by Lender under any Letter of Credit against presentation of a draft or certificate which substantially complies with the terms of such Letter of Credit; (vi) the invalidity or unenforceability of the Letter of Credit;
(vii) the examination of documents presented under a Letter of Credit exclusively by electronic or electro-optical means; or (viii) any other circumstances or happening whatsoever, whether or not similar to any of the foregoing, including
any act or omission, whether rightful or wrongful, of any present or future de jure or de facto governmental authority. None of the foregoing shall affect, impair or prevent the vesting of any rights or powers of Lender under this
Section 2.3. 
  

 -31- 

 (i) In furtherance and extension, and not in limitation, of the specific provisions set
forth above, any action taken or omitted by Lender under or in connection with any of the Letters of Credit or any related certificates, if taken or omitted in good faith in the absence of gross negligence or willful misconduct, shall not put Lender
under any resulting liability to Borrowers or relieve Borrowers of any of their obligations hereunder to Lender. 
 (j) (i)
Borrowers will pay to Lender, with respect to each Letter of Credit, a fee (“LOC Fee”) equal to the Applicable LOC Fee Percentage per annum on the amount available to be drawn under each Letter of Credit from, and including, the
issuance date of the Letter of Credit to and including the expiry date thereof (or, if earlier, the date on which the Letter of Credit is returned to Lender and is canceled). In addition, Borrowers will pay to Lender, on its demand for payment,
Lender’s then current issuance, opening, closing, transfer, amendment, draw, renewal, negotiation and other letter of credit administration fees, charges and out of pocket expenses with respect to each Letter of Credit. The LOC Fee is fully
earned by Lender when paid and will be due and payable on the issuance of each Letter of Credit. The LOC Fee will be calculated on the basis of the actual number of days elapsed in a 360-day year. If any Letter of Credit is cancelled for any reason
before the stated expiry date thereof, any LOC Fee paid in advance will not be refunded and will be retained by Lender solely for its account. 

(ii) For purposes of determining the Applicable LOC Fee Percentage, the Fixed Charge Coverage Ratio will, on and
after the First Pricing Grid Determination Date, be determined as of
June 30th and
December 31st of each Fiscal Year ending on and after
the First Pricing Grid Determination Date (each such date being a “Determination Date”). The “First Pricing Grid Determination Date” occurring after the Effective Date will be December 31, 2010. On
Lender’s receipt of the financial statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(a), 4.3(b) and 4.3(d) (as applicable) of this Agreement for the applicable Fiscal Quarter
or Fiscal Year then ended, the LOC Fee will be subject to adjustment in accordance with the table set forth in the definition of “Applicable LOC Fee Percentage” based on the Fixed Charge Coverage Ratio as of the end of such Fiscal Quarter
or Fiscal Year then ended so long as no Event of Default is existing as of the applicable effective date of adjustment. The foregoing adjustment, if applicable, (A) will become effective with respect to all Letters of Credit that are issued or
renewed on and after the first day of the first calendar month following delivery to Lender of the financial statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(a), 4.3(b) and 4.3(d)
(as applicable) of this Agreement for the applicable Fiscal Quarter or Fiscal Year then ended and (B) will remain in effect until the next succeeding effective date of adjustment pursuant to this clause (ii) of Section 2.3(j).
Each of the financial statements and Compliance Certificate required to be delivered to Lender must be delivered to Lender in compliance with Section 4.3 of this Agreement. If, however, either the financial statements or the Compliance
Certificate required to be delivered to Lender pursuant to Sections 4.3(a), 4.3(b) and 4.3(d) (as applicable) of this Agreement have not been delivered in accordance with Section 4.3 of this Agreement, then, at
Lender’s option, commencing on the date upon which such financial statements or Compliance Certificate should have been delivered in accordance with Section 4.3 of this Agreement and continuing until such financial statements or
Compliance Certificate are actually delivered in accordance with Section 4.3 of this Agreement, it shall be assumed for purposes of determining the Applicable LOC Fee Percentage, that the Fixed Charge Coverage Ratio was
£ 1.50 to 1.0 and the pricing associated therewith (i.e., Pricing Grid Level 1) will be applicable on the then applicable Determination Date. 

 

 -32- 

 (l) If (i) any law, treaty, rule, regulation, guideline or determination of a central
bank or a governmental authority or interpretation or application thereof by a central bank or governmental authority or (ii) compliance by Lender with any request or directive (whether having the force of law) from, or compliance by Lender
with any official pronouncement or statement of, or as a result of any audit, investigation, or enforcement action (whether or not against Lender) by, a central bank or other government authority shall either (A) impose, modify, deem or make
applicable any reserve, special deposits, assessment or similar requirement against letters of credit issued by Lender or (B) impose on Lender any other condition regarding this Agreement or any Letter of Credit, and, in Lender’s judgment
exercised in good faith, the result of any event referred to in clause (A) or (B) above is the increase of the cost to Lender of issuing or maintaining any Letter of Credit, then, within 10 Business Days after the demand therefor by
Lender, Borrowers will immediately pay to Lender, from time to time as specified by Lender, additional amounts sufficient to compensate Lender for such increased cost (the “Increased LOC Costs”), together with interest on each such
amount from the date demanded until payment in full thereof at a rate per annum equal to the then applicable interest rate on the Revolving Loans; provided, however, that Lender may charge Borrowers for such Increased LOC Costs only to the
extent that such cost is generally charged by Lender to its other similarly situated borrowers assuming Lender is legally empowered to do so. A certificate as to such Increased LOC Costs incurred by Lender, submitted by Lender to Borrowers, shall be
conclusive, absent manifest error, as to the amount thereof. 
 2.4 Funding of Revolving Loans; Lock Box; Collections.

 (a) Prior to the Termination Date with respect to the Line of Credit and subject to the other terms and conditions of this
Agreement, all disbursements of Revolving Loans will initially be made into a non-interest bearing, disbursement funding account maintained at Lender or an Affiliate of Lender (the “Funding Account”) structured and utilized for that
purpose in accordance with Lender’s (or as applicable, the applicable Lender Affiliate’s) policies and procedures, current account number 99903372. Prior to the Termination Date with respect to the Line of Credit and subject to the other
terms and conditions of this Agreement, funds in the Funding Account will then be made available to Borrowers via non-interest bearing controlled disbursement accounts maintained by Borrowers at Lender or an Affiliate of Lender (collectively, the
“Controlled Disbursement Account”) in accordance with Lender’s (or as applicable, the applicable Lender’s Affiliate’s) policies and procedures (current account numbers: 73352576 and 73355646); however, Lender
may, at any time hereafter, elect not to credit proceeds of Revolving Loans to the Controlled Disbursement Account, but Lender instead may establish non-controlled disbursement account or accounts (such as an operating account but exclusive of the
Funding Account) for Borrowers at Lender or an Affiliate of Lender and disburse proceeds of the Revolving Loans by crediting such non-controlled disbursement account(s) of Borrower(s) at Lender or an Affiliate of Lender. Borrowers hereby authorize
Lender without any further written or oral request of Borrowers to make advances of Revolving Loans to Borrowers in amounts necessary for the payment of checks and other items drawn on, and debits by Lender of, the Controlled Disbursement Account as
such checks and other items (“Presentments”) are presented to Lender or the applicable Lender Affiliate for payment, and debits are made by Lender, subject to the terms and conditions of this Agreement. In addition to advances of
Revolving Loans made pursuant to Lender’s (or as applicable, Lender’s Affiliate’s) controlled disbursement account system, Lender will, from time to time prior to the Termination Date with respect to the Line of Credit and subject to
the other terms and conditions of this Agreement, make advances of Revolving Loans via wire transfers or ACH payments so long as a Borrower has given Lender written notice, via facsimile transmission, electronic mail or otherwise, no later than 1:00
p.m. Cincinnati, Ohio time on the date Borrowers shall request that such Revolving Loan be advanced in the case of wire transfers and any other deadline imposed by Lender from time to time for ACH payments. The making of each Revolving Loan, whether
via the controlled disbursement account system or a written request by a Borrower, will be deemed to be a representation by Borrowers that (i) the Revolving Loan will not violate the terms of Section 2.1 and (ii) all Eligible
Inventory and Eligible Accounts then comprising the Borrowing Base meet all of Lender’s criteria for Eligible Inventory and for Eligible Accounts. 
  

 -33- 

 (b) Borrowers have established through Lender, and will continue at all times on and after
the occurrence of a Cash Dominion Triggering Event (as defined below), the use of, the post office box at the U.S. Post Office bearing the address: PO Box 630202, Cincinnati, Ohio 45263-0202, or such other address or addresses as Lender may notify
Borrowers from time to time (the “Lock Box”). At all times on and after the occurrence of a Cash Dominion Triggering Event, Borrowers will notify all of their respective customers and account debtors, which forward their Remittances
in paper form to the applicable Borrower, to forward all checks, drafts, money orders, and other items, cash and other remittances of every kind due the applicable Borrower (“Remittances”) to the Lock Box (such notices to be in such
form and substance as Lender may reasonably require from time to time). Lender will have sole access to the Lock Box at all times, and Borrowers will take all action necessary to grant Lender such sole access. At no time will any Borrower remove any
item from the Lock Box without Lender’s prior written consent, and no Borrower will notify any customer or account debtor to pay any Remittance to any other place or address, other than the address of Borrowers’ headquarters at times prior
to the occurrence of a Cash Dominion Triggering Event, without Lender’s prior written consent. If a Borrower should neglect or refuse to notify any customer or account debtor to pay any Remittance to the Lock Box, Lender will be entitled to
make such notification. At all times on and after the occurrence of a Cash Dominion Triggering Event, Borrowers will notify all of their respective customers and account debtors, which pay their Accounts by electronic funds transfer, to forward all
Remittances directly to the Collection Account (as defined below) by wire transfer or automated clearinghouse funds transfer (ACH) (such notices to be in such form and substance as Lender may require in good faith from time to time). Prior to the
occurrence of a Cash Dominion Triggering Event, Borrowers will notify all of their respective customers and account debtors, which pay their Accounts by electronic funds transfer, to forward all Remittances directly to the Funding Account or, at
Borrowers’ option, the Collection Account by wire transfer or automated clearinghouse funds transfer (ACH). Upon retrieval of Remittances and other proceeds of Accounts and other Loan Collateral from the Lock Box, Lender will deposit the same
into the Funding Account until such time as an Event of Default shall occur (such occurrence of an Event of Default being, the “Cash Dominion Triggering Event”) at which time all funds will thereafter be deposited by Lender into a
collection, non-interest bearing DDA depository account maintained at Lender, current account number 702-3362598 (“Collection Account”). Any Remittance or other proceeds of Accounts or other Loan Collateral received by a Borrower
shall be deemed held by such Borrower in trust and as fiduciary for Lender, and such Borrower immediately shall deliver the same, in its original form, to Lender by overnight delivery for deposit into the Lock Box (or the Funding Account prior to
the occurrence of a Cash Dominion Triggering Event). Pending such deposit, such Borrower will not commingle any such Remittance or other proceeds of Accounts or other Loan Collateral with any of any Borrower’s other funds or property, but such
Borrower will hold it separate and apart therefrom in trust for Lender until delivery is made to Lender as described above. All deposits to the Lock Box and the Collection Account will be Lender’s property to be applied, following a Cash
Dominion Triggering Event, against the Obligations in such order and method of application as may be elected by Lender in its discretion exercised in good faith and will be subject only to the signing authority designated from time to time by
Lender, and Borrowers shall have no interest therein or control over such deposits or funds. Borrowers shall have no interest in the Lock Box or the Collection Account nor control over the deposits or funds therein, and Lender shall have sole access
to the Collection Account and the Lock Box. Notwithstanding that Borrowers’ obligations with respect to the Lock Box and automatic sweep to the Collection Account become mandatory at all times on and after a Cash Dominion Triggering Event
occurs, Borrowers may not collect any Remittances through any provider of lock box or other cash management and treasury services other than Lender or its Affiliates or deposit any Remittances at any bank or other financial institution other than
Lender or its Affiliates. 
  

 -34- 

 (c) Each Business Day following a Cash Dominion Triggering Event, Lender will, or will cause
the applicable Lender Affiliate, automatically and without notice, request or demand by Borrowers, in accordance with Lender’s (or as applicable, the applicable Lender Affiliate’s) automatic sweep program, transfer all collected and
available funds in the Collection Account: (i) for application against the unpaid principal balance of all Revolving Loans bearing interest based on the Daily LIBOR Rate or the Prime Rate, as applicable, and (ii) to be held in the
Collection Account to the extent of any Revolving Loans bearing interest based on the Tranche LIBOR Rate. Pursuant to that automatic sweep program, Lender will either make Revolving Loans to the extent necessary to cover Presentments to the
Controlled Disbursement Account or to maintain a minimum collected, positive (i.e., “peg”) balance in the Funding Account of $500,000 at all times; however, in no event will the principal amount of the Revolving Loans
advanced pursuant to the herein described automatic sweep program exceed the maximum available amount provided for in Section 2.1(a). If such automatic sweep program is not then active, it shall be Borrowers’ responsibility to
maintain a minimum collected, positive (i.e., “peg”) balance in the Funding Account of $500,000 at all times. Until a Cash Dominion Triggering Event occurs, Borrowers shall have the right to issue orders and instructions, from time
to time, to Lender with respect to the disposition of the available and collected funds in the Funding Account, including whether or not to apply such funds against the outstanding Revolving Loan balance. Without limitation of the provisions in the
Security Agreement, and without limitation to the provisions below relating to the ownership of the Lock Box, the Collection Account and the deposits and funds therein, Lender shall have, and Borrowers hereby grant to Lender, a Lien on all funds
held in the Funding Account, the Controlled Disbursement Account, the Collection Account and Lock Box as security for the Obligations. The Funding Account, Controlled Disbursement Account, and Collection Account will not be subject to any deduction,
set-off, banker’s lien or any other right in favor of any Person other than Lender or an Affiliate of Lender and its Affiliates. If any Remittance deposited in the Collection Account is dishonored or returned unpaid for any reason, Lender, in
its discretion, may charge the amount of such dishonored or returned Remittance directly against Borrowers and any account maintained by any Borrower with Lender or the applicable Lender Affiliate and such amount shall be deemed part of the
Obligations. Neither Lender nor the applicable Lender Affiliate shall be liable for any loss or damage resulting from any error, omission, failure or negligence on the part of Lender or the applicable Lender Affiliate with respect to the operation
of the Funding Account, Controlled Disbursement Account, Collection Account, the Lock Box, or the services to be provided by Lender or the applicable Lender Affiliate under this Agreement except to the extent, but only to the extent, of any direct
damages, as opposed to any consequential, special or lost profit damages suffered by a Borrower from gross negligence or willful misconduct of Lender or the applicable Lender Affiliate. Until a payment is received by Lender for Lender’s account
in finally collected funds, all risks associated with such payment will be borne solely by Borrowers. 
  

 -35- 

 (d) For the purposes of calculating interest, determining Revolving Loan Availability and
the amount of Eligible Accounts, all Remittances and other proceeds of Accounts and other Loan Collateral deposited into the Collection Account shall be credited (conditional on final collection) against the outstanding Revolving Loan balance and
the then Eligible Accounts as funds become collected and available in accordance with Lender’s funds availability policies from time to time in effect. 

(e) From time to time, Lender or the applicable Lender Affiliate may adopt such regulations and procedures and changes as it may deem
reasonable and appropriate with respect to the operation of the Funding Account, the Controlled Disbursement Account, the Collection Account, the Lock Box, the automatic sweep program and the other services to be provided by Lender or the applicable
Lender Affiliate under this Agreement, and such regulations, procedures and changes need not be reflected by an amendment to this Agreement in order to be effective. 

(f) All service charges and costs related to the establishment and maintenance of the Funding Account, the Controlled Disbursement
Account, Collection Account, the Lock Box, the automatic sweep program, and Lender’s and its Affiliates’ treasury and cash management services shall be the sole responsibility of Borrowers, whether the same are incurred by Lender,
Lender’s Affiliates or Borrowers, and Lender, at its discretion, may charge the same against Borrowers and any account maintained by Borrowers with Lender or the applicable Lender Affiliate and the same shall be deemed part of the Obligations.

  

 -36- 

 2.5 Payment; Time of Payment; Late Payments. 

(a) Borrowers jointly and severally promise to pay and to perform, observe and comply with when due all of the Obligations. All payments
to be made by Borrowers on account of the Obligations will be made by Borrowers without setoff, deduction, offset, recoupment or counterclaim in immediately available funds. Borrowers shall make all payments of principal, interest and all other
Obligations no later than 2:00 p.m., Cincinnati, Ohio time, on the Business Day such payments are due; any and all amounts paid after such time shall be credited on the next Business Day. As an accommodation to Borrowers, on the date any payment of
interest or principal of the Loans, or any fee, charge or other Obligation is due, Lender is hereby authorized, in its discretion, to charge such amounts to the loan account with Lender as an advance of the Revolving Loans. All payments by Borrowers
under this Agreement will be in lawful money of the United States of America, and, unless otherwise provided in this Agreement or instructed by Lender in writing from time to time, Borrowers will make all payments required under this Agreement and
under any of the other Loan Documents in immediately available funds to an account designated by Lender from time to time. 

(b) If any payment is not made when due under this Agreement or any of the other Loan Documents and, at the time payment was due, there
was insufficient Revolving Loan Availability to charge such payment to the loan account with Lender as an advance of the Revolving Loans, Borrowers shall pay to Lender a late payment fee equal to two percent (2%) of any payment not paid when
due (whether by maturity, acceleration or otherwise). In addition, all Obligations shall, after the occurrence and during the continuance of an Event of Default, bear interest at the Default Rate without notice to Borrowers; provided that
this Section 2.5(b) shall not be deemed to constitute a waiver of any Event of Default or an agreement by Lender to permit any late payments whatsoever. “Default Rate” means the applicable rates of interest set forth in
the Notes plus an additional 2.0% per annum. In no event shall the interest rate accruing under the Notes be increased to be in excess of the maximum interest rate permitted by applicable state or federal usury laws then in effect.

 2.6 One General Obligation; Cross-Collateralized. All advances of credit to, or for the benefit of, Borrowers under
this Agreement and under any other Loan Document constitute one loan, and all of the Obligations constitute one obligation. The Loans and all other advances or extensions of credit to, or for the benefit of, Borrowers under this Agreement or the
other Loan Documents and all other Obligations are made on the security of all of the Loan Collateral. The limits on outstanding advances against the Borrowing Base are not intended and shall not be deemed to limit in any way Lender’s security
interest in, or other Liens on, the Accounts, Inventory, Equipment, General Intangibles, or any other Loan Collateral. 
 2.7
Unused Line Fee. (a) Commencing on July 1, 2010 and continuing on the first day of each and every calendar month thereafter until the Obligations are fully paid and satisfied (and, as applicable, on the date this Agreement is
terminated), Borrowers will pay to Lender a fee (“Unused Line Fee”) in an amount equal to the result obtained by multiplying (i) the difference between (A) the Revolving Commitment and (B) the average daily Revolving
Loans advanced to Borrowers during the preceding calendar month (or portion thereof during which any portion of the Revolving Loans was outstanding or during which this Agreement was in full force and effect) for which the Unused Line Fee is being
determined by (ii) the result obtained (expressed as a percentage) by multiplying the Applicable Unused Line Fee Percentage by a fraction, the numerator of which is the sum of days in such calendar month during which this Agreement was
in full force and effect (or during which any portion of the Revolving Loans was outstanding) and the denominator of which is 360. The Unused Line Fee is payable in arrears by Borrowers. 

 

 -37- 

 (b) For purposes of determining the Applicable Unused Line Fee
Percentage, the Fixed Charge Coverage Ratio will, on and after the First Pricing Grid Determination Date, be determined as of
June 30th and
December 31st of each Fiscal Year ending on and after
the First Pricing Grid Determination Date (each such date being a “Determination Date”). The “First Pricing Grid Determination Date” occurring after the Effective Date will be December 31, 2010. On
Lender’s receipt of the financial statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(a), 4.3(b) and 4.3(d) (as applicable) of this Agreement for the applicable Fiscal Quarter
or Fiscal Year then ended, the Unused Line Fee will be subject to adjustment in accordance with the table set forth in the definition of “Applicable Unused Line Fee Percentage” based on the Fixed Charge Coverage Ratio as of the end of such
Fiscal Quarter or Fiscal Year then ended so long as no Event of Default is existing as of the applicable effective date of adjustment. The foregoing adjustment, if applicable, will become effective on and after the first day of the first calendar
month following delivery to Lender of the financial statements and Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(a), 4.3(b) and 4.3(d) (as applicable) of this Agreement for the applicable
Fiscal Quarter or Fiscal Year then ended until the next succeeding effective date of adjustment pursuant to this Section 2.7. Each of the financial statements and Compliance Certificate required to be delivered to Lender must be
delivered to Lender in compliance with Section 4.3 of this Agreement. If, however, either the financial statements or the Compliance Certificate required to be delivered to Lender pursuant to Sections 4.3(a), 4.3(b) and
4.3(d) (as applicable) of this Agreement have not been delivered in accordance with Section 4.3 of this Agreement, then, at Lender’s option, commencing on the date upon which such financial statements or Compliance
Certificate should have been delivered in accordance with Section 4.3 of this Agreement and continuing until such financial statements or Compliance Certificate are actually delivered in accordance with Section 4.3 of this
Agreement, it shall be assumed for purposes of determining the Applicable Unused Line Fee Percentage, that the Fixed Charge Coverage Ratio was £ 1.50 to 1.0 and the pricing associated therewith
(i.e., Pricing Grid Level 1) will be applicable on the then applicable Determination Date. 
 2.8 [Intentionally
Omitted]. 
 2.9 [Intentionally Omitted]. 

2.10 Consolidated Borrowings. To induce Lender to enter into this Agreement and to make Loans in the manner set forth in this
Agreement, each Borrower hereby represents, warrants, covenants and states to Lender that: (i) Borrowers are substantially dependent upon each other for their respective working capital, strategic management, financial needs and technology;
(ii) Borrowers desire to utilize their borrowing potential on a consolidated basis, to the extent(s) possible as if they were merged into a single entity and, consistent with realizing such potential, to make available to Lender security
commensurate with the amount and nature of their aggregate borrowings; (iii) each of Borrowers has determined that it will benefit specifically and materially from the advances of credit contemplated by this Agreement and that under a joint and
several loan facility it is able to obtain financing on terms more favorable than otherwise available to it separately; and (iv) Borrowers have requested and bargained for the structure and terms of and security for the advances contemplated by
this Agreement. 
  

 -38- 

 2.11 Joint Obligations. The obligations of Borrowers under the Loan Documents are
joint, several and primary. No Borrower will be or be deemed to be an accommodation party with respect to any of the Loan Documents. Each Borrower hereby irrevocably designates Parent as its representative and agent on its behalf for the purposes of
issuing requests for advances of Loans, giving instructions with respect to the disbursement of the proceeds of the Loans, selecting interest rate options, requesting Letters of Credit, giving and receiving all other notices and consents hereunder
or under any of the other Loan Documents and taking all other actions (including in respect of compliance with covenants) on behalf of any Borrower or Borrowers under the Loan Documents which are permitted to be taken by a Borrower. Parent hereby
accepts such appointment. Lender may regard any notice or other communication pursuant to any Loan Document from Parent as a notice or communication from all Borrowers, and may give any notice or communication required or permitted to be given to
any Borrower or Borrowers hereunder to Parent on behalf of such Borrower or Borrowers. Each Borrower agrees that each notice, election, representation and warranty, covenant, agreement and undertaking made on its behalf by Parent shall be deemed for
all purposes to have been made by such Borrower and shall be binding upon and enforceable against such Borrower to the same extent as if the same had been made directly by such Borrower.

incorporation, bylaws/regulations or other governing documents of any Loan Party, nor violate any agreement or instrument by which any Loan Party is bound (the performance or non-performance of which could reasonably be expected to have a Material
Adverse Effect) nor result in the creation of a Lien on any assets of any Loan Party except the Lien granted to Lender under the Loan Documents. Each Loan Party has duly executed and delivered to Lender this Agreement and the other Loan Documents to
which it is a party or otherwise bound and they are valid and binding obligations of each Loan Party enforceable according to their respective terms, except as limited by equitable principles and by bankruptcy, insolvency or similar laws affecting

Lender, Loan Parties shall furnish to Lender statements in conformity with the requirements of Federal Reserve Form U-1. 
 3.5
Business; Supplier and Distribution Agreements. No Loan Party is a (a) party to or subject to any contract or agreement containing a covenant made by a Loan Party not to compete in any line of business with any Person or (b) party

tax. There are not in effect any waivers of applicable statutes of limitations for federal, foreign, state or local taxes for any period. No Loan Party is a party to any tax-sharing agreement or arrangement. Each Loan Party’s fiscal year is
from January 1 to December 31. 
  

 -40- 

 3.8 Financial Condition. All financial statements relating to Loan Parties which have
been, or may hereafter be delivered, by Loan Parties or on their behalf to Lender are, and will be, true and correct and fairly present, and will present, in all material respects the financial condition and results of operations of Loan Parties at
the date and for the period indicated therein and has been prepared in accordance with GAAP. No Loan Party has any Indebtedness of any kind that is prohibited by the terms of this Agreement. As of the Signature Date, there has not occurred any
change in the financial condition of any Loan Party which has had a Material Adverse Effect. No Loan Party has suffered any damage, destruction or loss which has had a Material Adverse Effect since the submission of the most recent audited financial
statements of the Loan Parties to Lender. 
 3.9 Title. Each Borrower has good title to its property (exclusive of that
property for which it has only a leasehold estate), free and clear of all Liens and encumbrances of any kind except for any Permitted Liens. Except as specifically set forth on Schedule 3.9, none of the equipment, included in the appraisal,

3.10 Defaults. Each Loan Party is in compliance with all agreements to which it is a party or by which any of its property is
bound, a default under which could reasonably be expected to have a Material Adverse Effect. There does not now exist any default or violation by any Loan Party of or under any of the terms, conditions or obligations of: (a) its certificate of
incorporation/articles of incorporation, bylaws/regulations, other charter documents, or (b) any indenture, mortgage, deed of trust, franchise, permit, contract, agreement or other instrument to which any Loan Party is a party or by which it is
bound, the performance of non-performance of which could reasonably be expected to have a Material Adverse Effect. The consummation of the transactions contemplated by this Agreement shall not result in such default or violation. 

3.11 Environmental Laws. 

(a) Each Borrower has obtained all permits, licenses and other authorizations or approvals which are required under Environmental Laws
which, if not so obtained by such Borrower, could reasonably be expected to have a Material Adverse Effect. Each Borrower is in compliance with (i) all terms and conditions of such required permits, licenses, authorizations and approvals, and
(ii) all other limitations, restrictions, conditions, standards, prohibitions, requirements, obligations, schedules and timetables contained in the Environmental Laws except, in each case, for such violations which could not be reasonably
expected to have a Material Adverse Effect.

3.13 ERISA. The Loan Parties and all Persons that, along with the Loan Parties, would be treated as a single employer under ERISA
or the Internal Revenue Code (an “ERISA Affiliate”), are in compliance with all of their obligations arising out of, or in connection with, any “employee benefit plan”, as that term is defined in Section 3(3) of ERISA
which a Loan Party or an ERISA Affiliate sponsors or maintains or for which a Loan Party has an obligation to contribute except: (a) as set forth on Schedule 3.13 and (b) for such violations which would not reasonably be expected to
have a Material Adverse Effect. Neither any Loan Party nor any of its ERISA Affiliates (each, a “Subject Plan”): (i) maintains a Pension Plan subject to Title IV of ERISA or subject to the minimum funding standards under
Section 412 of the Internal Revenue Code as to which a Loan Party or any ERISA Affiliate may have any liability, except, in each case, as set forth on Schedule 3.13 or (ii) is obligated to contribute to any Multiemployer Plan except

 3.15 Restrictions; Labor Disputes; Labor Contracts. No Loan Party is a party or
subject to, any charge, corporate restriction, judgment, decree or order, for which a Loan Party’s compliance or non-compliance could reasonably be expected to have a Material Adverse Effect. Except as set forth on Schedule 3.15, no Loan
Party is, as of the Signature Date, (a) a party to any collective bargaining agreement or other labor contract or (b) the subject of any labor dispute which could reasonably be expected to have a Material Adverse Effect. Except as set
forth on Schedule 3.15, no union or other labor organization is, to any Loan Party’s knowledge, seeking to organize, or to be recognized as, a collective bargaining unit of employees of any Loan Party or any of its Subsidiaries or for
any similar purpose. To any Loan Party’s knowledge, no key employee of such Loan Party is subject to any agreement in favor of anyone other than such Loan Party which restricts or limits that individual’s right to engage in the type of
business activity conducted by such Loan Party in any manner which could materially impair the ability of such individual to carry out his or her duties with such Loan Party or to use any property or confidential information or which grants to any
Person, other than such Loan Party, any rights to inventions or other ideas susceptible to legal protection developed or conceived by any such key employee of such Loan Party.

being a “reportable transaction” (within the meaning of Treasury Regulation Section 1.6011-4). If any Loan Party determines to take any action inconsistent with such intention, it will promptly notify Lender thereof and deliver to
Lender a duly completed IRS Form 8886 or any successor form. If any Loan Party so notifies Lender, Loan Parties acknowledge that (a) Lender may treat the Loans and/or Letters of Credit as part of a transaction that is subject to Treasury
Regulation Section 301.6112-1, and Lender will maintain the lists and other records required by such Treasury Regulation and (b) Lender may disclose without limitation of any kind, any information with respect to the “tax
treatment” and “tax structure” (in each case, within the meaning of Treasury Regulation Section 1.6011-4) of the transactions contemplated hereby and all materials of any kind (including opinions or other tax analyses) that are
provided to Lender relating to such tax treatment and tax structure. 
 3.18 Full Disclosure. No representation or
warranty made by any Loan Party or any of its Affiliates, as the case may be, in this Agreement, any other Loan Document to which they are a party, or in any other document furnished from time to time in connection herewith or therewith contains or
will contain at the time such representation is made or such document furnished, any untrue statement of a material fact or omits or will omit to state any material fact necessary to make the statements herein or therein not misleading.

representations and warranties set forth in Section 3 to remain true, complete and accurate as of the date hereof and as of each day on which a Loan is made hereunder, the Loan Parties shall update in writing any Schedules provided for
in Section 3 promptly upon learning of any circumstance which may have the effect of making any such representation or warranty contained in Section 3 untrue or misleading. Such Schedules, upon being updated by a Loan Party
in accordance with this Agreement, will become the Schedules referenced in this Agreement. The requirement of the Loan Parties to update any Schedule provided for herein is not, and may not be construed to be, a modification of any of the covenants
of this Agreement or a cure of any Event of Default occurring prior to any such update, as result of, or existing at the time of any such update without the waiver of such Event of Default by Lender. 

Section 4. Affirmative Covenants. Loan Parties covenant with, and represent and warrant to, Lender that, from and after the Effective Date

engaged in by Borrowers, considered as a whole, as of the date of this Agreement. 
 4.8 Compliance with Laws. Each Loan
Party shall comply with all federal, state and local laws, regulations and orders applicable to it or its assets, including all Environmental Laws, in all respects applicable to such Loan Party’s business or assets except, in each case, for

applicable law, the violation of which could be reasonably expected to have a Material Adverse Effect. 
 4.9 Notice of
Default and Labor Matters. Each Loan Party shall, within three (3) Business Days after any officer of a Loan Party has knowledge thereof, give notice to Lender of: (a) the occurrence of any event or the existence of any condition which

reasonable in amount and reasonably incurred or paid by Lender or any of its officers, employees, Affiliates or agents in connection with: (a) the preparation, negotiation, procurement, review, administration or enforcement of this Agreement,
any of the other Loan Documents or any instrument, agreement, document, policy, consent, waiver, subordination, release of lien, termination statement, satisfaction of mortgage, financing statement or other lien search, recording or filing related

foreclosure or other litigation or proceedings or otherwise. The Costs shall be due and payable upon demand by Lender. If any Loan Party fails to pay the Costs upon such demand, Lender is entitled to disburse such sums as an advance under the Line
of Credit. If there is insufficient Revolving Loan Availability to charge such Costs to the loan account with Lender as an advance of the Revolving Loans, the Costs shall bear interest from the date Borrowers receive demand for payment at the
Default Rate. This provision shall survive the termination of this Agreement and/or the repayment of any amounts due or the performance of any Obligation. Notwithstanding anything to the contrary in this Section 4.10, in connection with
each field examination or verification by Lender of any of the Loan Collateral or a Loan Party conducted after the Effective Date, Loan Parties will pay to Lender (i) a fee at the then current rate (currently $850.00) per day (based on an 8
hour day plus reasonable out-of-pocket expenses incurred, including travel, lodging and meals) per auditor or field examiner for the services of Lender’s auditors and field examiners and (ii) the out-of-pocket fees, costs and expenses paid

discharge any Lien prohibited hereby, or to comply with any other Obligation, Lender may, but shall not be obligated to, pay, satisfy, discharge or bond the same for the account of Loan Parties, and to the extent permitted by law and at the option
of Lender, all monies so paid by Lender on behalf of a Loan Party shall be deemed Loans and Obligations. 
  

 -48-

unless otherwise required by applicable law: 
 (a) cease advancing any Revolving Loans, declare all Obligations to be
immediately due and payable, whereupon such Obligations shall immediately become due and payable, and terminate this Agreement and all obligations of Lender under this Agreement; 

(b) proceed to enforce payment of the Obligations and to realize upon the Loan Collateral or any property securing the Obligations,
including causing all or any part of the Loan Collateral to be transferred or registered in its name or in the name of any other Person, with or without designation of the capacity of such nominee, and Borrowers shall be liable for any deficiency
remaining after disposition of any Loan Collateral; 
 (c) offset and apply to all or any part of the Obligations all moneys,
credits and other property of any nature whatsoever of any Borrower now or at any time hereafter in the possession of, in transit to or from, under the control or custody of, or on deposit with (whether held by a Borrower individually or jointly
with another Person), Lender or its Affiliates, including certificates of deposit; and/or 
 (d) exercise any and all rights and
remedies provided by applicable law and the Loan Documents. 
 6.3 No Remedy Exclusive. No remedy set forth herein is
exclusive of any other available remedy or remedies, but each is cumulative and in addition to every other remedy available under this Agreement, the Loan Documents or as may be now or hereafter existing at law, in equity or by statute, and each may
be exercised together, separately and in any order. Borrowers waive any requirement of marshaling of assets that may be secured by any of the Loan Documents. 

6.4 Effect of Termination; Voluntary Termination. 

(a) Any termination of this Agreement shall not affect any rights of any party or any obligation of any party to the other, arising prior
to the effective date of such termination, and the provisions hereof shall continue to be fully operative until all transactions entered into, rights created or Obligations incurred prior to such termination have been fully disposed of, concluded or
liquidated. The security interest, other Liens and rights granted to Lender hereunder and under the Loan Documents shall continue in full force and effect, notwithstanding the termination of this Agreement or the fact that no Loans are outstanding
to Borrowers, until all of the Obligations have been paid in full and satisfied. 
  

 -60- 

 (b) Borrowers may terminate this Agreement (i) by giving Lender written notice
(“Termination Notice”) of the date on which this Agreement is to terminate (“Voluntary Termination Date”) at least 30 days before the Voluntary Termination Date, and (ii) by paying on any such Voluntary
Termination Date all of the Obligations. Upon the Voluntary Termination Date, (1) all Loans and all other Obligations will automatically and immediately become due and payable, (2) Borrowers will cause all Letters of Credit to be replaced
or cash collateralized on terms satisfactory to Lender; and (3) Lender’s obligations under this Agreement and the other Loan Documents arising on and after that effective date of termination will automatically terminate immediately,

 6.5 No Adequate Remedy at Law. Borrowers
recognize that no remedy at law shall provide adequate relief to Lender in the event that a Loan Party shall fail to pay, perform, observe or discharge any of the Obligations under this Agreement or the other Loan Documents to which it is a party or
otherwise bound, and, accordingly, Lender and the Loan Parties agree that Lender shall be entitled to temporary and permanent injunctive relief in any such case without the necessity of proving that it has incurred actual damages. 

6.6 Actions in Respect of Letters of Credit. If any Event of Default shall have occurred and be continuing, Lender may, whether in
addition to taking any of the actions described in this Section 6 or otherwise, if any Letters of Credit shall have been issued, make demand upon any Borrower to, and forthwith upon such demand Borrowers will, pay to Lender in same day
funds at Lender’s office designated in such demand, for deposit in a special non-interest bearing cash collateral account (the “Letter of Credit Collateral Account”) to be maintained at such office of Lender, an amount equal to
the Letter of Credit Exposure from time to time in existence. The Letter of Credit Collateral Account shall be in the name of Lender (as a cash collateral account), and under the sole dominion and control of Lender exercised in good faith (with sole
right of withdrawal) and subject to the terms of this Agreement and the other Loan Documents. On each drawing under a Letter of Credit, Lender shall seek reimbursement from any amounts then on deposit in the Letter of Credit Collateral Account;
however, if (a) no amounts are then on deposit in the Letter of Credit Collateral Account, (b) the amount then on deposit in the Letter of Credit Collateral Account is insufficient to pay the amount of such drawing, or
(c) Lender is legally prevented or restrained from immediately applying amounts on deposit in the Letter of Credit Collateral Account, then the amount of each unreimbursed drawing under such Letter of Credit and payment required to be made
under this Section 6.6 shall automatically be converted into a Revolving Loan made on the date of such drawing for all purposes of this Agreement. To the extent that Lender applies amounts on deposit in the Letter of Credit Collateral
Account as provided in this Section 6.6, and, thereafter, such application (or any portion thereof) is rescinded or any amount so applied must otherwise be returned by Lender upon the insolvency, bankruptcy or reorganization of a
Borrower or otherwise, then the amount so rescinded or returned shall automatically be converted into a Revolving Loan made on the date of such drawing for all purposes of this Agreement.

Documents and all other instruments, agreements, documents, policies, consents, waivers, subordinations, releases of liens, termination statements, satisfaction of mortgages, financing statements, lien searches, recordings, or filings related
thereto, whether or not any particular portion of the transactions contemplated during such negotiations is ultimately consummated. 

7.2 Conditions to Each Revolving Loan and Letter of Credit. Lender shall have no obligation to advance additional Revolving Loans
or issue any Letters of Credit unless, as to each such Loan, the following statements shall be true and correct: 
 (a) Each of
the representations and warranties contained herein and in the other Loan Documents shall be correct in all material respects, and each shall be deemed to be reaffirmed as of the date of each such Revolving Loan or Letter of Credit with the same
effect as though such representations and warranties had been made again on and as of each day of the term of this Agreement subject to such changes as are not prohibited hereby or do not constitute Events of Default; 

 

 -62- 

 (b) No event shall have occurred and be continuing, or would result from such Revolving Loan
or Letter of Credit, which constitutes an Event of Default, or would constitute an Event of Default but for the requirement that notice be given or lapse of time or both; 

(c) (i) The aggregate unpaid principal amount of the Revolving Loans after giving effect to such Revolving Loan shall not violate the
lending limits set forth in Section 2.1 of this Agreement and (ii) the Letter of Credit Availability, after giving effect to such Letter of Credit, is greater than zero Dollars; and 

(d) No law or regulation prohibits, and no order, judgment or decree of any arbitrator or governmental authority enjoins or restrains
Lender, from making the requested advance. 
 The acceptance by a Loan Party of the proceeds of each Revolving Loan and the
execution and delivery of a Letter of Credit Application by a Loan Party shall be deemed to constitute a representation and warranty by the Loan Parties that the conditions in this Section 7.2, other than (i) those that have been
waived in writing by Lender, or (ii) the type described in clause (d) of this Section 7.2, have been satisfied. 

Section 8. Participations. 

8.1 Participation. Lender, in the ordinary course of its commercial banking business and in accordance with applicable law, may at
any time after the Effective Date, sell to one or more lenders or other entities (“Participants”) participating interests in the Loans, the Loan Collateral or other security provided to Lender, or any other interests of Lender under
this Agreement or the other Loan Documents. 
 8.2 Participant Consents. Each Loan Party acknowledges that Participants
have and will have certain rights under their respective participation agreements with Lender that may, subject to the terms of the participation agreements, require Lender to obtain the consent (collectively, “Participant
Consents”) of some or all of the Participants before Lender takes or refrains from taking certain actions (other than as expressly required by the Loan Documents) or grants certain waivers, consents or approvals in respect of the Loans, the
Loan Documents or the Loan Collateral. None of the Participants, however, will have Participant Consent rights which are greater than those rights and remedies Lender has under the Loan Documents. In addition, from time to time, Lender may request
instructions from the Participants in respect of the actions, waivers, consents or approvals which by the terms of any of the Loan Documents Lender is permitted or required to take or to grant or to not take or grant (“Participant
Instructions”). If the Participant Consents are, pursuant to the terms of the respective participation agreements, required or Participant Instructions are requested, Lender will (i) be absolutely empowered to take or refrain from
taking any action (other than as expressly required by the Loan Documents) or withhold any waiver, consent or approval and (ii) not be under any liability whatsoever to any Person, including any Borrower and any Participant, from taking or
refraining from taking any action or withholding any waiver, consent or approval under any of the Loan Documents until it has received the requisite Participant Consents or, as applicable, the Participant Instructions. Further, in the event a
Participant fails to fund its portion of any of the Loans, Lender shall be under no obligation to fund any portion of any of the Loans that was not funded by such Participant. Borrowers do hereby indemnify, defend, save and hold Lender, its
Affiliates, and their respective officers, directors, attorneys, and employees harmless of, from and against all claims, demands, liabilities, judgments, losses, damages, costs and expenses, joint or several (including all accounting fees and
reasonable attorneys’ fees), that Lender or any such indemnified party may incur as a result of a Participant failing to fund its portion of any Loan or failing to give a Participant Consent. 

 

 -63- 

 8.3 Information. Subject to the confidentiality provisions of
Section 9.13, each Loan Party authorizes Lender to disclose to any Participant or prospective Participant or any assignee or prospective assignee of Lender’s rights under the Loan Documents any and all financial information in
Lender’s possession concerning each Loan Party which has been delivered to Lender by a Loan Party pursuant to the Loan Documents or in connection with Lender’s credit evaluation of the Loan Parties or which has been obtained independently
by Lender in its credit evaluation or audit of the Loan Parties. 
 8.4 Law Requirements. Nothing in the Loan Documents
will prohibit Lender from pledging or assigning its interests in the Loans to any Federal Reserve Lender in accordance with applicable law. 

Section 9. Miscellaneous Provisions. 

9.1 General. This Agreement, the exhibits and the other Loan Documents are the complete agreement of the parties hereto and
supersede all previous understandings and agreements relating to the subject matter hereof. This Agreement may be amended only in writing signed by the party against whom enforcement of the amendment is sought. This Agreement may be executed in
counterparts. If any part of this Agreement is held invalid, illegal or unenforceable, the remainder of this Agreement shall not in any way be affected. This Agreement is and is intended to be a continuing agreement and shall remain in full force
and effect until (i) the Obligations are finally and irrevocably paid in full and the Line of Credit is terminated and (ii) Lender has no further obligations to make a Loan or issue any Letter of Credit under this Agreement. Any documents
delivered by, or on behalf of, any Person by fax transmission or other electronic delivery of an image file reflecting the execution hereof: (i) may be relied on by all Persons as if the document were a manually signed original and
(ii) will be binding on all Persons for all purposes of the Loan Documents. If there is any conflict, ambiguity, or inconsistency, in Lender’s judgment, between the terms of this Agreement or any of the other Loan Documents, then the
applicable terms and provisions, in Lender’s judgment, providing Lender with greater rights, remedies, powers, privileges, or benefits will control. With respect to each Loan Party, Lender is authorized to rely in good faith on any telephonic
or other oral communication which shall be received by it from anyone reasonably believed by Lender to be an officer of a Loan Party or any other authorized signer of a Loan Party as designated in any certificate or letter given by a Loan Party to
Lender from time to time. 
  

 -64- 

 9.2 Waiver by Borrowers. Each Loan Party waives notice of non-payment (except as
expressly required by this Agreement or the other Loan Documents), demand, presentment, protest or notice of protest of any Accounts or other Loan Collateral, the benefit of all valuation and appraisement laws following the occurrence and during the
continuance of an Event of Default, and all other notices (except those notices specifically provided for in this Agreement). Each Loan Party hereby waives all suretyship defenses, including all defenses set forth in Section 3-605 of the
Uniform Commercial Code (the “UCC”). Such waiver is entered to the full extent permitted by Section 3-605(i) of the UCC. To the fullest extent not prohibited by law, each Loan Party waives and agrees not to assert any claim
against Lender under any theory for consequential, special, indirect or punitive damages. 
 9.3 Binding Effect. This
Agreement shall be binding upon and inure to the benefit of the respective legal representatives, successors and assigns of the parties hereto; however, no Loan Party may assign or transfer any of its rights or delegate any of its Obligations
under this Agreement or any of the Loan Documents to which it is a party or otherwise bound, by operation of law or otherwise. Without any Loan Party’s consent, Lender (and any subsequent assignee) may (i) transfer and assign any or all of
its rights or delegate any of its duties under this Agreement or (ii) transfer or assign partial interests in the Loans or grant participations in the Loans to other Persons. Subject to the confidentiality provisions of
Section 9.13, Lender may disclose to all prospective and actual assignees and Participants all financial, business and other information about each Loan Party which Lender may possess at any time. 

9.4 Subsidiaries. If a Borrower has any Subsidiaries at any time during the term of this Agreement with the consent of Lender, the
term “Borrower” in each representation, warranty and covenant herein shall mean such Borrower and each Subsidiary, individually and in the aggregate, and such Borrower shall cause each Subsidiary to be in compliance therewith. The
existence of references to a Borrower’s Subsidiaries any place in this Agreement is for a matter of convenience only. Any references to Subsidiaries of a Borrower set forth herein shall not in any way be construed as consent by Lender to the
establishment, maintenance or acquisition of any Subsidiary. 
 9.5 Security. The Obligations are secured as provided in
this Agreement, the Security Documents, in the other Loan Documents and in each other document or agreement that by its terms secures the repayment or performance of the Obligations. 

9.6 Survival. All representations, warranties, covenants and agreements made by Borrowers herein and in the other Loan Documents
shall survive the execution and delivery of this Agreement, the other Loan Documents and the issuance of the Notes. 
 9.7
Delay or Omission. No delay or omission on the part of Lender in exercising any right, remedy or power arising from any Event of Default shall impair any such right, remedy or power or any other right remedy or power or be considered a waiver
or any right, remedy or power or any Event of Default nor shall the action or omission to act by Lender upon the occurrence of any Event of Default impair any right, remedy or power arising as a result thereof or affect any subsequent Event of
Default of the same or different nature.

Loan Parties’ Counsel will not affect the validity or effectiveness of any notice or notification given to such Loan Party. 

9.9 No Partnership. Nothing contained herein or in any of the Loan Documents is intended to create or shall be construed to create
any partnership, joint venture or other relationship between Lender and the Loan Parties other than as expressly set forth herein or therein and shall not create any joint venture, partnership or other relationship. 

 

 -66- 

 9.10 Electronic Communication. Lender may, in its discretion, elect, from time to
time, to receive certain information, including reports, otherwise required by the terms of this Agreement or the other Loan Documents (“Reports”) from Borrowers via electronic mail transmission (“e-mail”). Lender
will designate from time to time its e-mail address to Borrowers (the “Lender E-mail Address”). All e-mail transmissions of Reports from Borrowers shall contain the information as specified in this Agreement, shall be formatted or
displayed in a manner and order substantially similar to that shown in this Agreement or otherwise required by Lender and shall conform to the specifications described in this Agreement. Borrowers will be solely responsible for the confidentiality
of the contents of e-mail transmissions during transmission to the Lender E-mail Address. Borrowers will be responsible for the accuracy of all information provided to Lender via e-mail transmission to the Lender E-mail Address, and any information
so received by Lender will be deemed to have been submitted by and received from Borrowers. In the event of a failure of the transmission of the Reports, it is the responsibility of Borrowers to transmit the contents of any pending transmission to
Lender using an alternative method which is timely and in accordance with this Agreement. Borrowers agree that, by sending Lender the Reports via e-mail transmission, Borrowers are certifying the truthfulness and accuracy in all material respects of
the Reports submitted each and every time Borrowers send Lender the Reports. Borrowers further agree that, on each occasion when Borrowers send Lender e-mail transmissions containing Reports, Borrowers are warranting and representing to Lender the
truthfulness and accuracy in all material respects of the representations and warranties relevant to that Report set forth in the relevant Loan Document. Borrowers consent to and represent that it is Borrowers’ intent that by Borrowers’
insertion of a Borrower’s name in the subject line of the transmitting e-mail, or on the Reports (including the header and/or the certification line), Borrowers intend such to constitute a legally binding and enforceable signature of Borrowers,
and in all aspects the legal equivalent of Borrowers’ handwritten signatures. 
 9.11 Indemnification. If after
receipt of any payment of all or part of the Obligations, Lender is for any reason compelled to surrender such payment to any Person because such payment is determined to be void or voidable as a preference, impermissible setoff, or diversion of
trust funds, or for any other reason, this Agreement shall continue in full force and effect and Borrowers shall be liable to, and shall indemnify, save and hold Lender, its officers, directors, attorneys, and employees harmless of and from the
amount of such payment surrendered. The provisions of this Section shall be and remain effective notwithstanding any contrary action which may have been taken by Lender in reliance on such payment, and any such contrary action so taken shall be
without prejudice to Lender’s rights under this Agreement and shall be deemed to have been conditioned upon such payment becoming final, indefeasible and irrevocable. In addition, Borrowers shall indemnify, defend, save and hold Lender, its
Affiliates, and their respective officers, directors, attorneys, and employees harmless of, from and against all claims, demands, liabilities, judgments, losses, damages, costs and expenses, joint or several (including all accounting fees and
reasonable attorneys’ fees), that Lender or any such indemnified party may incur arising out of (a) this Agreement or any of the other Loan Documents, (b) any act taken by Lender hereunder, (c) any transaction financed by a Loan,
or (d) any Other Taxes, except to the extent, as determined by a court of competent jurisdiction in a final non-appealable judgment or order: (i) of the willful misconduct or gross negligence of such indemnified party, (ii) such claim
for indemnification is based on a material breach by Lender of its express duties or obligations to a Loan Party under the Loan Documents, or (iii) such claim for indemnification is based on a willful violation by Lender of its express duties
or obligations under applicable law. The provisions of this Section shall survive the termination of this Agreement. 
  

 -67- 

 9.12 Power of Attorney. Each Loan Party hereby appoints Lender, as its
attorney-in-fact to indorse its name on all instruments and other documents payable to such Loan Party in order for Lender to perform its services under this Agreement, including under Section 2.4. Upon the occurrence and during the
continuation of an Event of Default, Lender shall be entitled, but not required, to perform any action or execute any document required to be taken or executed by any Loan Party under this Agreement and the other Loan Documents; provided that
Borrowers shall not be relieved of such obligation under this Agreement and the other Loan Documents. The powers of attorney described in this Section are coupled with an interest and are irrevocable. 

9.13 Confidentiality. Lender agrees that it will use reasonable efforts not to disclose without the prior consent of Parent (other
than to Lender’s employees, auditors, advisors, consultants, Affiliates and counsel) any information with respect to the Loan Parties to the extent and in the manner such information is kept confidential in accordance with Lender’s privacy
policies and procedures with respect to its customers generally and as mandated by applicable law, provided that Lender may disclose any such information: (a) as has become generally available to the public unless such availability is as
a result of the breach by Lender of this Agreement, (b) as may be required or appropriate in any report, statement or testimony submitted to or examination conducted by any governmental authority having or claiming to have jurisdiction over
Lender, (c) as may be required or appropriate in response to any summons, subpoena, or civil investigative demand or in connection with any litigation or governmental investigation, (d) in order to comply with any requirement of applicable
law, (e) to any prospective or actual transferee or Participant in connection with any contemplated transfer or participation of any of the Obligations or any interest therein, provided that each such prospective or actual transferee or
Participant agrees to be bound by the confidentiality provisions contained in this Section 9.13, (f) to other financial institutions or investment funds with respect to which Lender has a contractual relationship in accordance with
Lender’s regular banking procedures in order to carry out the services to be performed by Lender for a Loan Party, provided that each such other financial institution or investment fund agrees to be bound by the confidentiality
provisions contained in this Section 9.13, (g) to any nationally recognized rating agency that requires access to information regarding Lender’s investment portfolio in connection with such rating agency’s issuance of
ratings with respect to Lender, provided that Lender advises such rating agency of the confidential nature of such information, (h) as may be required or appropriate in connection with protecting, preserving, exercising or enforcing (or
planning to exercise or enforce) any of Lender’s rights in, under or related to the Loan Documents after the occurrence of an Event of Default; (i) as permitted by Sections 3.17 and 9.10; (j) to respond to routine
informational requests in accordance with the Code of Ethics for the Exchange of Credit Information promulgated by The Robert Morris Associates (or any successor thereto) or other applicable industry standards relating to the exchange of credit
information, (k) if such information was available to or known by Lender prior to its disclosure to Lender by a Loan Party or its representatives, and (l) which became available to Lender from a source other than a Loan Party or its
representatives, provided that Lender does not have reason to know that such source is bound by a confidentiality agreement regarding such information.
