 Exhibit 4.4 
 HYCO INTERNATIONAL, INC. 
 1998 STOCK OPTION PLAN 
 EFFECTIVE DATE: JUNE 5, 1998 
  

	I.	INTRODUCTION 

 1.1. Purposes. The purposes of the 1998 Hyco
International, Inc. Stock Option Plan (the “Plan”) of Hyco International, Inc. (the “Company”) are (i) to align the interests of the Company’s stockholders and the recipients of options under this Plan by increasing the
proprietary interest of such recipients in the Company’s growth and success, (ii) to advance the interests of the Company by attracting and retaining officers, other key employees, consultants, independent contractors, agents and
well-qualified persons who are not officers or employees of the Company (“Non-Employee Directors”) for service as directors of the Company and (iii) to motivate such persons to act in the long-term best interests of the Company’s
stockholders. 
 1.2. Administration. (a) This Plan shall be administered by a committee (the “Committee”) designated by the
Board of Directors of the Company (the “Board”) consisting of two or more members of the Board. 
 (b) The Committee
shall, subject to the terms of this Plan, select eligible officers, other key employees, consultants, independent contractors, agents and Non-Employee Directors for participation in this Plan and shall determine the number of shares of Common Stock
subject to each option granted hereunder, the exercise price of such option, the time and conditions of exercise of such option and all other terms and conditions of such option, including, without limitation, the form of the option agreement. The
Committee shall, subject to the terms of this Plan, interpret this Plan and the application thereof, establish rules and regulations it deems necessary or desirable for the administration of this Plan and may impose, incidental to the grant of an
option, conditions with respect to the grant, such as limiting competitive employment or other activities. All such interpretations, rules, regulations and conditions shall be final, binding and conclusive. Notwithstanding the foregoing, in the case
of the grant of an option to a Non-Employee Director who is a member of the Committee, the terms and conditions of such option shall be subject to approval by the Board. Each option shall be evidenced by a written agreement (an
“Agreement”) between the Company and the optionee setting forth the terms and conditions of such option. 
 (c) A
majority of the Committee shall constitute a quorum. The acts of the Committee shall be either (i) acts of a majority of the members of the Committee present at any meeting at which a quorum is present or (ii) acts approved in writing by a
majority of the members of the Committee without a meeting. 
 1.3. Eligibility. Participants in this Plan shall consist of such officers,
other key employees, consultants, independent contractors, agents and Non-Employee Directors of the Company, its subsidiaries from time to time and any other entity designated by the Board of the Committee (individually a “Subsidiary” and
collectively the “Subsidiaries”) as the Committee in its sole discretion may select from time to time. For purposes of this Plan, references to employment shall also mean an agency or independent contractor relationship and references to
employment by the Company shall also mean employment by a Subsidiary. The Committee’s selection of a person to participate in this Plan at any time shall not require the Committee to select such person to participate in this Plan at any other
time. 
 1.4. Shares Available. Subject to adjustment as provided in Section 3.7, 1,300,781 shares of the Common Stock, $0.001 par
value, of the Company (“Common Stock”), shall be available for grants of options under this Plan, reduced by the sum of the aggregate number of shares of Common Stock which become subject 

  

 Page 1 

 
to outstanding options. To the extent that shares of Common Stock subject to an outstanding option are not issued or delivered by reason of the expiration,
termination, cancellation or forfeiture of such option or by reason of the delivery or withholding of shares of Common Stock to pay all or a portion of the exercise price of such option, or to satisfy all or a portion of the tax withholding
obligations relating to such option, then such shares of Common Stock shall again be available under this Plan. 
  

	II.	STOCK OPTIONS 

 2.1. Grants of Stock Options. The Committee
may, in its discretion, grant options to purchase shares of Common Stock to such eligible persons as may be selected by the Committee. Each option shall be a non-qualified stock option. 
 2.2. Terms of Stock Options. Options shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of this Plan, as the Committee shall deem advisable: 
 (a) Number of Shares and Purchase Price.
The number of shares of Common Stock subject to an option and the purchase price per share of Common Stock purchasable upon exercise of the option shall be determined by the Committee, provided that, in the case of options granted during the
two-year period commencing on the effective date of the Plan set forth above, the purchase price per share of Common Stock shall be not less than $3.20. 
 (b) Option Period and Exercisability. The period during which an option may be exercised shall be determined by the Committee. The Committee may, in its discretion, establish performance measures or other criteria
which shall be satisfied or met as a condition to the grant of an option or to the exercisability of all or a portion of an option. The Committee shall determine whether an option shall become exercisable in cumulative or non-cumulative installments
and in part or in full at any time. An exercisable option, or portion thereof, may be exercised only with respect to whole shares of Common Stock. 
 (c) Method of Exercise. An option may be exercised (i) by giving written notice to the Company specifying the number of whole shares of Common Stock to be purchased and accompanied by payment therefor in full (or
arrangement made for such payment to the Company’s satisfaction) either (A) in cash, (B) by delivery of previously owned whole shares of Common Stock (which the optionee has held for at least six months prior to the delivery of such
shares or which the optionee purchased on the open market and in each case for which the optionee has good title, free and clear of all liens and encumbrances) having a Fair Market Value, as defined in paragraph (d) below, determined as of the
date of exercise, equal to the aggregate purchase price payable by reason of such exercise, (C) in cash by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise or (D) a combination of
(A), (B) and (C), in each case to the extent set forth in the Agreement relating to the option and (ii) by executing such documents as the Company may reasonably request. The Committee shall have sole discretion to disapprove of an
election pursuant to any of clauses (B)-(D). Any fraction of a share of Common Stock which would be required to pay such purchase price shall be disregarded and the remaining amount due shall be paid in cash by the optionee. No certificate
representing Common Stock shall be delivered until the full purchase price therefor has been paid (or arrangement made for such payment to the Company’s satisfaction). 
 (d) For purposes of the Plan, “Fair Market Value” shall mean, with respect to each share of Common Stock as of any date of
determination, (i) the average of the daily Closing Prices for the ten consecutive trading days immediately preceding the date of determination or (ii) if on such date the shares of such class or series of capital stock are not listed or
admitted for trading on any national securities exchange and are not quoted on NASDAQ or any 

  

 Page 2 

 
similar service, the cash amount that a willing buyer would pay a willing seller (neither acting under compulsion) in an arm’s-length transaction
without time constraints per share of Common Stock as of such date, viewing the Corporation on a going concern basis, as determined in good faith by the Board of Directors, whose determination shall be conclusive. “Closing Price” shall
mean, with respect to each share of Common Stock as of any date of determination, (i) the last reported sale price regular way or, in case no such sale takes place on such day, the average of the closing bid and asked prices regular way, in
either case as reported on the principal national securities exchange on which such class or series of capital stock is listed or admitted for trading or (ii) if such class or series of capital stock is not listed or admitted for trading on any
national securities exchange, the last reported sale price or, in case no such sale takes place on such day, the average of the highest reported bid and the lowest reported asked quotation for such class or series of capital stock, in either case as
reported on NASDAQ or a similar service if NASDAQ is no longer reporting such information. 
 2.3. Termination of Employment. Unless
otherwise specified in the Agreement relating to an option, if an optionee’s employment with the Company or directorship with the Company terminates for any reason, each option held by such optionee shall be exercisable only to the extent that
such option is exercisable on the effective date of such optionee’s termination of employment or directorship, as the case may be, and may thereafter be exercised by such optionee (or such optionee’s legal representative or similar person)
until and including the earlier to occur of (a) the date which is set forth in the Agreement relating to such option after the effective date of such optionee’s termination of employment or directorship, as the case may be, and
(b) the expiration date of the term of such option; provided that, in the case of an optionee who is an employee of the Company, if such optionee’s employment is terminated for Cause (as defined below), all options held by such optionee
shall terminate automatically on the effective date of such optionee’s termination of employment. For purposes of this Plan, “Cause” shall mean (i) optionee’s commission of a felony or any other crime involving moral
turpitude, fraud, misrepresentation, embezzlement or theft, (ii) optionee’s engaging in any other activity that is contrary, inimical or harmful, in each case in a material respect, to the Company or any of its Subsidiaries, monetarily or
otherwise, as determined by a majority of the Board; (iii) optionee’s material malfeasance (including without limitation, any intentional act of fraud or theft), misconduct, gross negligence or misfeasance in connection with the
performance of his duties; (iv) optionee’s significant violation of any statutory or common law duty of loyalty to the Company or any of its Subsidiaries; (v) optionee’s material breach of optionee’s employment agreement (if
any) with the Company or any of its Subsidiaries (or any other agreement between optionee and the Company or any of its Subsidiaries relating to disclosure, use or ownership of intellectual property and other information, competition or solicitation
of employees or customers) or optionee’s material breach of a material Company policy (including without limitation, disclosure or misuse of any confidential or competitively sensitive information or trade secrets of the Company or a
Subsidiary); or (vi) optionee’s refusal or failure to carry out directives or instructions of the Board that are consistent with the scope and nature of optionee’s duties and responsibilities, in the case of clause (v) or
(vi) above, only if such breach or failure continues for more than 10 days following written notice from the Company describing such breach or failure. 
  

	III.	GENERAL 

 3.1. Effective Date and Term of Plan. This Plan
has been submitted to the stockholders of the Company for approval and was approved by the affirmative vote of all of the shares of Common Stock by the unanimous written consent of the Company’s stockholders dated as of the date hereof
determined in accordance with applicable law and, accordingly, is effective as of the date hereof. No option may be exercised prior to the date of such stockholder approval. This Plan shall terminate when shares of Common Stock are no longer
available for the 

  

 Page 3 

 
grant of options, unless terminated earlier by the Board. Termination of this Plan shall not affect the terms or conditions of any option granted prior to
termination. 
 3.2. Amendments. The Board may amend this Plan as it shall deem advisable, subject to any requirement of stockholder approval
required by applicable law, rule or regulation, including Rule 16b-3 under the Exchange Act and Sections 162(m) and 280G of the Code; provided, however, that no amendment shall be made without stockholder approval if such amendment would increase
the maximum number of shares of Common Stock available under this Plan (subject to Section 3.7). No amendment may impair the rights of a holder of an outstanding option without the consent of such holder. 
 3.3. Agreement. No option shall be valid until an Agreement is executed by the Company and the optionee and, upon execution by the Company and the
optionee and delivery of the Agreement to the Company, such option shall be effective as of the effective date set forth in the Agreement. 
 3.4. Non-Transferability. No option hereunder shall be transferable other than (i) by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company, (ii) to the Company or
any of its Subsidiaries or (ii) as otherwise permitted under Rule 16b-3 under the Exchange Act as set forth in the Agreement relating to such option. Except to the extent permitted by the foregoing sentence, each option may be exercised during
the optionee’s lifetime only by the optionee or the optionee’s legal representative or similar person. Except as permitted by the second preceding sentence, no option hereunder shall be sold, transferred, assigned, pledged, hypothecated,
encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of any option
hereunder, such option and all rights thereunder shall immediately become null and void. 
 3.5. Tax Withholding. The Company shall have the
right to require, prior to the issuance or delivery of any shares of Common Stock, payment by the optionee of any Federal, state, local or other taxes which may be required to be withheld or paid in connection with an option hereunder. An Agreement
may provide that (i) the Company shall withhold whole shares of Common Stock which would otherwise be delivered upon exercise of the option having an aggregate Fair Market Value determined as of the date the obligation to withhold or pay taxes
arises in connection with the option (the “Tax Date”) in the amount necessary to satisfy any such obligation or (ii) the optionee may satisfy any such obligation by any of the following means: (A) a cash payment to the Company,
(B) delivery to the Company of previously owned whole shares of Common Stock (which the optionee has held for at least six months prior to the delivery of such shares or which the optionee purchased on the open market and in each case for which
the optionee has good title, free and clear of all liens and encumbrances) having an aggregate Fair Market Value determined as of the Tax Date, equal to the amount necessary to satisfy any such obligation, (C) authorizing the Company to withhold
whole shares of Common Stock which would otherwise be delivered upon exercise of the option having an aggregate Fair Market Value determined as of the Tax Date, equal to the amount necessary to satisfy any such obligation, (D) a cash payment by
a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise or (E) any combination of (A), (B), (C) and (D), in each case to the extent set forth in the Agreement relating to the option;
provided, however, that the Committee shall have sole discretion to disapprove of an election pursuant to any of clauses (B)-(E). Any fraction of a share of Common Stock which would be required to satisfy such an obligation shall be disregarded and
the remaining amount due shall be paid in cash by the optionee. 
 3.6. Restrictions on Shares. Each option hereunder shall be subject to the
requirement that if at any time the Company determines that the listing, 

  

 Page 4 

 
registration or qualification of the shares of Common Stock subject to such option upon any securities exchange or under any law, or the consent or approval
of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares thereunder, such shares shall not be delivered unless such listing, registration, qualification,
consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company may require that certificates evidencing shares of Common Stock delivered pursuant to any option hereunder bear
a legend indicating that the sale, transfer or other disposition thereof by the holder is prohibited except in compliance with the Securities Act of 1933, as amended, and the rules and regulations thereunder. 
 3.7. Adjustments. In the event of any stock split, dividend or similar change, the number and class of securities available under this Plan, the number
and class of securities subject to each outstanding option and the purchase price per security shall be appropriately adjusted by the Committee, such adjustments to be made in the case of outstanding options without an increase in the aggregate
purchase price. The decision of the Committee regarding any such adjustment shall be final, binding and conclusive. If any adjustment would result in a fractional security being (a) available under this Plan, such fractional security shall be
disregarded, or (b) subject to an option under this Plan, the Company shall pay the optionee, in connection with the first exercise of the option in whole or in part occurring after such adjustment, an amount in cash determined by multiplying
(A) the fraction of such security (rounded to the nearest hundredth) by (B) the excess, if any, of (x) the Fair Market Value on the exercise date over (y) the exercise price of the option. 
 3.8. Change in Control. 
 (a)
In the sole discretion of the Committee, the terms of an Agreement may provide that, in the event of the occurrence of a Change in Control, as defined in paragraph (b) below or as defined in such Agreement, some or all of an optionee’s
outstanding options shall, immediately upon the occurrence of such Change in Control or at such other time specified in the Agreement, become exercisable in part or in full. The terms of such Agreement may provide, in the event of the occurrence of
a Change in Control, for the terms and conditions (i) pursuant to which any outstanding option under the Agreement may be surrendered to the Company and canceled by the Company, including the terms of any consideration to be paid by the Company
to the optionee as a result thereof and (ii) in the event of the occurrence of a Change in Control described in paragraph (b)(3) or (4) below, pursuant to which the number and class of shares shall be substituted for each outstanding share of
Common Stock subject to the option under the Agreement. 
 (b) “Change in Control” shall mean: 
 (i) the acquisition by any individual, entity or group (a “Person”), including any “person” within the meaning of
Section 13(d)(3) or 14(d)(2) of the Exchange Act, of beneficial ownership within the meaning of Rule 13d-3 promulgated under the Exchange Act, of 50% or more of either (x) the then outstanding shares of common stock of the Company (the
“Outstanding Common Stock”) or (y) the combined voting power of the then outstanding securities of the Company entitled to vote generally in the election of directors (the “Outstanding Voting Securities”); excluding,
however, the following: (A) any acquisition directly from the Company (excluding any acquisition resulting from the exercise of an exercise, conversion or exchange privilege unless the security being so exercised, converted or exchanged was
acquired directly from the Company), (B) any acquisition by the Company, (C) any acquisition by an employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company, (D) any
acquisition by the Company’s stockholders as of the date hereof or their respective affiliates or (E) any acquisition by any corporation pursuant to a transaction which complies 

  

 Page 5 

 
with clauses (1), (2) and (3) of subsection (iii) of this Section 3.8(b); provided further, that for purposes of clause (B), if any Person
(other than the Company or any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company) shall become the beneficial owner of 50% or more of the Outstanding Common Stock or 50% or
more of the Outstanding Voting Securities by reason of an acquisition by the Company, and such Person shall, after such acquisition by the Company, become the beneficial owner of any additional shares of the Outstanding Common Stock or any
additional Outstanding Voting Securities and such beneficial ownership is publicly announced, such additional beneficial ownership shall constitute a Change in Control; 
 (ii) individuals who, as of the date hereof, constitute the Board of Directors (the “Incumbent Board”) cease for any reason to
constitute at least a majority of such Board; provided that any individual who becomes a director of the Company subsequent to the date hereof whose election, or nomination for election by the Company’s stockholders, was approved by the vote of
at least a majority of the directors then comprising the Incumbent Board shall be deemed a member of the Incumbent Board; and provided further, that any individual who was initially elected as a director of the Company as a result of an actual or
threatened election contest, as such terms are used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act, or any other actual or threatened solicitation of proxies or consents by or on behalf of any Person other than the Board shall
not be deemed a member of the Incumbent Board; 
 (iii) approval by the stockholders of the Company of a reorganization,
merger or consolidation or sale or other disposition of all or substantially all of the assets of the Company (a “Corporate Transaction”); excluding, however, a Corporate Transaction pursuant to which (1) all or substantially all of
the individuals or entities who are the beneficial owners, respectively, of the Outstanding Common Stock and the Outstanding Voting Securities immediately prior to such Corporate Transaction will beneficially own, directly or indirectly, more than
50% of, respectively, the outstanding shares of common stock, and the combined voting power of the outstanding securities of such corporation entitled to vote generally in the election of directors, as the case may be, of the corporation resulting
from such Corporate Transaction (including, without limitation, a corporation which as a result of such transaction owns the Company or all or substantially all of the Company’s assets either directly or indirectly), (2) no Person (other
than: the Company; any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company; the corporation resulting from such Corporate Transaction; and any Person which beneficially owned,
immediately prior to such Corporate Transaction, directly or indirectly, 50% or more of the Outstanding Common Stock or the Outstanding Voting Securities, as the case may be) will beneficially own, directly or indirectly, 50% or more of,
respectively, the outstanding shares of common stock of the corporation resulting from such Corporate Transaction or the combined voting power of the outstanding securities of such corporation entitled to vote generally in the election of directors
and (3) individuals who were members of the Incumbent Board will constitute at least a majority of the members of the board of directors of the corporation resulting from such Corporate Transaction; or 
 (iv) approval by the stockholders of the Company of a plan of complete liquidation or dissolution of the Company. 
 3.9. No Right of Participation or Employment. No person shall have any right to participate in this Plan. Neither this Plan nor any option granted
hereunder shall confer upon any person any right to continued employment by the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the
employment or any person at any time without liability hereunder. 
 3.10. Rights as Stockholder. No person shall have any rights as a
stockholder of the Company with respect to any shares of Common Stock which are subject to an option hereunder until such person becomes a stockholder of record with respect to such shares of Common Stock. 
  

 Page 6 

 3.11. Designation of Beneficiary. If permitted by the Company, an optionee may file with the Committee a
written designation of one or more persons as such optionee’s beneficiary or beneficiaries (both primary and contingent) in the event of the optionee’s death. To the extent an outstanding option granted hereunder is exercisable, such
beneficiary or beneficiaries shall be entitled to exercise such option. Each beneficiary designation shall become effective only when filed in writing with the Committee during the optionee’s lifetime on a form prescribed by the Committee. The
spouse of a married optionee domiciled in a community property jurisdiction shall join in any designation of a beneficiary other than such spouse. The filing with the Committee of a new beneficiary designation shall cancel all previously filed
beneficiary designations. If an optionee fails to designate a beneficiary, or if all designated beneficiaries of an optionee predecease the optionee, then each outstanding option hereunder held by such optionee, to the extent exercisable, may be
exercised by such optionee’s executor, administrator, legal representative or similar person. 
 3.12. Governing Law. This Plan, each
option hereunder and the related Agreement, and all determinations made and actions taken pursuant thereto, to the extent not otherwise governed by the Code or the laws of the United States, shall be governed by the laws of the State of Delaware and
construed in accordance therewith without giving effect to principles of conflicts of laws.

 CREDIT AGREEMENT 
 Harris Trust and Savings Bank 
 Chicago, Illinois 
 Ladies and Gentlemen: 
 The undersigned HYCO Holdings LLC, a Delaware limited liability company
(“Holdings”) and HYCO Alabama LLC, a Delaware limited liability company (“Alabama”; and collectively with Holdings, the “Borrowers” and each is referred to individually as a “Borrower”), apply to you (the
“Bank”) for your commitment, subject to the terms and conditions hereof and on the basis of the representations and warranties hereinafter set forth, to extend credit to the Borrowers, all as more fully hereinafter set forth. All
capitalized terms used herein without definition shall have the same meanings herein as such terms are defined in Section 5.1 hereof. 
 SECTION 1. THE
CREDITS. 
 Section 1.1. Revolving Credit. Subject to the terms and conditions hereof, the Bank agrees to extend a revolving credit (the
“Revolving Credit”) to the Borrowers which may be availed of by the Borrowers from time to time during the period from and including the date hereof to but not including the Termination Date, at which time the commitment of the Bank to
extend credit under the Revolving Credit shall expire. The Revolving Credit may be utilized by the Borrowers in the form of Revolving Loans and Letters of Credit, all as more fully hereinafter set forth, provided that the aggregate principal amount
of Revolving Loans and Letters of Credit outstanding at any one time shall not exceed the lesser of (i) $13,000,000 (the “Revolving Credit Commitment”) and (ii) the Borrowing Base as then determined and computed. During the
period from and including the date hereof to but not including the Termination Date, the Borrowers may use the Revolving Credit Commitment by borrowing, repaying and reborrowing Revolving Loans in whole or in part and/or by having the Bank issue
Letters of Credit, having such Letters of Credit expire or otherwise terminate without having been drawn upon or, if drawn upon, reimbursing the Bank for each such drawing, and having the Bank issue new Letters of Credit, all in accordance with the
terms and conditions of this Agreement. Notwithstanding any other provision of this Agreement to the contrary, the Bank shall have the right from time to time to establish reserves against the amount of Revolving Credit which the Borrowers may
otherwise request hereunder in such amounts and with respect to such matters as the Bank shall deem necessary or appropriate in its reasonable judgment. The amount of such reserves shall be subtracted from the Borrowing Base, and shall be deemed
usage of the Revolving Credit Commitment, in each case when calculating the amount of availability under the Revolving Credit for purposes of Sections 1, 3.7, and 7 hereof. Additionally, the Bank may from time to time reduce the percentages
applicable to Eligible Receivables and Eligible Inventory as they relate to the Borrowing Base if the Bank determines in its reasonable judgment that there has been a material adverse change in circumstances relating to any or all of such Collateral
from those circumstances in existence on the date of this Agreement or in the condition (financial or otherwise) of any Borrower or any Guarantor. So long as no Default or Event of Default then exists, the Bank agrees to give the Borrowers 5
Business Days’ prior notice of the establishment of any such reserve or the reduction of any such percentage. 
  

 1 

 Section 1.2. Revolving Loans. Subject to the terms and conditions hereof, the Revolving Credit may
be availed of by the Borrowers in the form of loans (individually a “Revolving Loan” and collectively the “Revolving Loans”). The Revolving Loans shall be made against and evidenced by a single joint and several promissory note
of the Borrowers in the form (with appropriate insertions) attached hereto as Exhibit A (the “Revolving Note”). The Revolving Note shall be dated the date of issuance thereof and be expressed to bear interest as set forth in Section 2
hereof. The Revolving Note, and all Revolving Loans evidenced thereby, shall mature and be due and payable in full on the Termination Date. Without regard to the principal amount of the Revolving Note stated on its face, the actual principal amount
at any time outstanding and owing by the Borrowers on account of the Revolving Note shall be the sum of all Revolving Loans made hereunder less all payments of principal actually received by the Bank. 
 Section 1.3. Letters of Credit. (a) General Terms. Subject to the terms and conditions hereof, the Revolving Credit may be availed of by the
Borrowers in the form of standby and commercial letters of credit issued by the Bank for the account of any Borrower (individually a “Letter of Credit” and collectively the “Letters of Credit”), provided that the aggregate amount
of Letters of Credit issued and outstanding hereunder shall not at any one time exceed $500,000. For purposes of this Agreement, a Letter of Credit shall be deemed outstanding as of any time in an amount equal to the maximum amount which could be
drawn thereunder under any circumstances and over any period of time plus any unreimbursed drawings then outstanding with respect thereto. If and to the extent any Letter of Credit expires or otherwise terminates without having been drawn upon or
any drawing thereon has been reimbursed or become a Revolving Credit Loan, the availability under the Revolving Credit Commitment shall be reinstated to the extent of such reimbursement, conversion or the amount of the expiring or terminating Letter
of Credit. 
 (b) Term. Each Letter of Credit issued hereunder shall expire not later than the earlier of (i) twelve (12) months
from the date of issuance, subject to renewal for additional twelve (12) month periods by the Bank in its sole discretion (or be cancelable not later than twelve (12) months from the date of issuance and each renewal) or (ii) the
Termination Date. 
 (c) General Characteristics. Each Letter of Credit issued hereunder shall be payable in U.S. dollars, conform to the
general requirements of the Bank for the issuance of standby or commercial letters of credit, as the case may be, as to form and substance, and be a letter of credit which the Bank may lawfully issue. 
 (d) Applications. At the time a Borrower requests a Letter of Credit to be issued (or prior to the first issuance of a Letter of Credit in the case of a
continuing application), such Borrower shall execute and deliver to the Bank an application for such Letter of Credit in the form then customarily prescribed by the Bank (individually an “Application” and collectively the
“Applications”). Subject to the other provisions of this subsection, the obligation of such Borrower to reimburse the Bank for drawings under a Letter of Credit shall be governed by the Application for such Letter of Credit. Anything
contained in the Applications to the contrary notwithstanding, (i) the Borrowers shall be jointly and severally liable for all obligations owing under each Application, (ii) in the event the Bank is not reimbursed by the Borrowers for the
amount the Bank pays on any drawing under a Letter of Credit issued hereunder by 2:00 p.m. (Chicago time) on the date when such drawing is paid, the obligation of the Borrowers to reimburse the Bank for the amount of such drawing paid shall bear
interest (which the Borrowers jointly and severally hereby promise to pay on demand) from and after the date the drawing is paid until payment in full thereof at the rate per annum determined by adding 2.0% to the sum of the Base Rate as from time
to time in effect plus the Applicable Margin, (ii) the Borrowers shall pay fees in connection with each Letter of Credit as set forth in Section 3 hereof, and (iii) except as otherwise provided in Section 3 hereof, prior to the
occurrence of an Event of Default, the Bank will not call for the 

  

 2 

 
funding of a Letter of Credit by the Borrowers prior to being presented with a drawing thereunder. 
 Section 1.4. Term Loan. Subject to the terms and conditions hereof, the Bank agrees to make a loan (the “Term Loan”) to the Borrowers in
the amount of $4,800,000 on or before December 30, 2004, at which time the commitment of the Bank to make the Term Loan shall expire. The Term Loan shall be made against and evidenced by a single joint and several promissory note of the
Borrowers in the form (with appropriate insertions) attached hereto as Exhibit B (the “Term Note”). The Term Note shall be dated the date of issuance thereof and be expressed to bear interest as set forth in Section 2 hereof. The Term
Note, and the Term Loan evidenced thereby, shall mature in monthly principal installments, payable on the first Business Day of each month of each year (commencing February 1, 2005), with each principal installment to be in the amount of $57,000.00
except that the final installment of the Term Loan shall be in the amount of all principal not sooner paid and shall be due and payable on the Termination Date, the final maturity thereof. 
 Section 1.5. Manner and Disbursement of Loans. (a) The Borrowers shall give written or telephonic notice to the Bank (which notice shall be
irrevocable once given) by no later than 1:00 p.m. (Chicago time) on the date any Borrower requests the Bank to make a Loan hereunder. Each such notice shall specify the date of the Loan requested (which must be a Business Day) and the amount of
such Loan. The Borrowers agree that the Bank may rely upon any written or telephone notice given by any person the Bank in good faith believes is an Authorized Representative without the necessity of independent investigation. 
 (b) The Borrowers hereby irrevocably authorize the Bank to make Revolving Loans from time to time hereunder for payment of any Obligation then due and
payable (whether such Obligation is for interest then due on a Loan, reimbursement under an Application or otherwise), and any such Revolving Loan may be made without regard to the provisions of Section 7 hereof. The Borrowers acknowledge and
agree, however, that the Bank shall not be under any obligation to make a Revolving Loan under this Section 1.5(b), and the Bank shall incur no liability to the Borrowers or any other Person for refusing to make a Revolving Loan under this
Section 1.5(b). 
 (c) Subject to the provisions of Section 7 hereof, the proceeds of each Loan made under Section 1.5(a) hereof
shall be made available to the relevant Borrower at the principal office of the Bank in Chicago, Illinois, in immediately available funds, in the case of the initial Loans made hereunder, in accordance with the terms of the written disbursement
instructions of the Borrowers, and, in the case of each subsequent Loan, by deposit to Alabama’s general account with the Bank known as Account Number 293-810-8 or as otherwise agreed upon between the Borrowers and the Bank. The proceeds of
each Revolving Loan made under Section 1.5(b) hereof shall be disbursed by the Bank by way of direct payment of the relevant Obligation. 
 Section 1.6. Appointment of Holdings as Agent for Borrowers; Reliance by Bank. (a) Appointment. Alabama hereby irrevocably appoints Holdings as its agent hereunder to make requests on its behalf under Section 1 hereof for
Loans and/or Letters of Credit, to execute Applications for such Letters of Credit, to make interest rate elections under Section 2 hereof, and to take any other action contemplated by the Loan Documents with respect to credit extended
hereunder to them. The Bank shall be entitled to conclusively presume that any action by Holdings under the Loan Documents is taken on behalf of all of the Borrowers. 
 (b) Reliance. All requests for Loans may be written or oral, including by telephone or telecopy. The Borrowers agree that the Bank may rely on any such notice given by any person the Bank in good faith believes is an
Authorized Representative without the necessity of independent investigation (the Borrowers hereby indemnifying the Bank from any liability or loss ensuing from such reliance), and in the event any such telephonic or other oral notice conflicts

  

 3 

 
with any written confirmation, such oral or telephonic notice shall govern if the Bank has acted in reliance thereon. 
 SECTION 2. INTEREST AND CHANGE IN CIRCUMSTANCES. 
 Section
2.1. Interest Rate Options. (a) Generally. The outstanding principal balance of the Loans (all of the indebtedness evidenced by a single Note bearing interest at the same rate for the same period of time being hereinafter referred to as a
“Portion” of such Note) shall bear interest with reference to the Base Rate (“Base Rate Portions”) or, at the option of the Borrowers and subject to the terms and conditions hereof, with reference to an Adjusted LIBOR
(“LIBOR Portions”). All of the indebtedness evidenced by a Note which bears interest with reference to a particular Adjusted LIBOR for a particular Interest Period shall constitute a single LIBOR Portion applicable to such Note, and all of
the indebtedness evidenced by a Note which is not part of a LIBOR Portion shall constitute a single Base Rate Portion applicable to such Note. There shall not be more than six (6) LIBOR Portions applicable to the Notes outstanding at any one
time. Anything contained herein to the contrary notwithstanding, the obligation of the Bank to create, continue or effect by conversion any LIBOR Portion shall be conditioned upon the fact that at the time no Default or Event of Default shall have
occurred and be continuing. The Borrowers hereby jointly and severally promise to pay interest on each Portion of the Notes at the rates and times specified in this Section 2. 
 (b) Base Rate Portions. Each Base Rate Portion shall bear interest at the rate per annum determined by adding the Applicable Margin to the Base Rate as
in effect from time to time, provided that, upon the occurrence and during the continuation of any Event of Default hereunder, such Portion shall bear interest, whether before or after judgment, until payment in full thereof at the rate per annum
determined by adding 2.0% to the interest rate which would otherwise be applicable thereto from time to time. Interest on each Base Rate Portion shall be due and payable monthly in arrears on the first Business Day of each month of each year
(commencing on the first such date occurring after the date hereof) and at maturity of the relevant Note, and interest after maturity (whether by lapse of time, acceleration or otherwise) shall be due and payable upon demand. 
 (c) LIBOR Portions. Each LIBOR Portion shall bear interest for each Interest Period selected therefor at a rate per annum determined by adding the
Applicable Margin to the Adjusted LIBOR for such Interest Period, provided that upon the occurrence and during the continuation of any Event of Default hereunder, such Portion shall bear interest, whether before or after judgment, until payment in
full thereof through the end of the Interest Period then applicable thereto at the rate per annum determined by adding 2.0% to the interest rate which would otherwise be applicable thereto, and effective at the end of such Interest Period such LIBOR
Portion shall automatically be converted into and added to the relevant Base Rate Portion and shall thereafter bear interest at the interest rate applicable to the relevant Base Rate Portion after default. Interest on each LIBOR Portion shall be due
and payable on the last day of each Interest Period applicable thereto and, with respect to any Interest Period in excess of three (3) months, on the date occurring every three (3) months after the date such Interest Period began and at
the end of such Interest Period, and interest after maturity (whether by lapse of time, acceleration or otherwise) shall be due and payable upon demand. The Borrowers shall notify the Bank on or before 11:00 a.m. (Chicago time) on the third Business
Day preceding the end of an Interest Period applicable to a LIBOR Portion whether such LIBOR Portion is to continue as a LIBOR Portion, in which event the Borrowers shall notify the Bank of the new Interest Period selected therefor; and in the event
the Borrowers shall fail to so notify the Bank, such LIBOR Portion shall automatically be converted into and added to the relevant Base Rate Portion as of and on the last day of such Interest Period. 
  

 4 

 Section 2.2. Minimum Amounts. Each LIBOR Portion shall be in a minimum amount of $500,000 or such
greater amount which is an integral multiple of $100,000. 
 Section 2.3. Manner of Rate Selection. The Borrowers shall notify the Bank
by 11:00 a.m. (Chicago time) at least three (3) Business Days prior to the date upon which the Borrowers request that any LIBOR Portion be created or that any part of the relevant Base Rate Portion be converted into a LIBOR Portion. If any
request is made to convert a LIBOR Portion into the relevant Base Rate Portion hereunder, such conversion shall only be made so as to become effective as of the last day of the Interest Period applicable thereto. All requests for the creation,
continuance, and conversion of LIBOR Portions under this Agreement shall be irrevocable. Such requests may be written or oral and the Bank is hereby authorized to honor telephonic requests for creations, continuances, and conversions received by it
from any Person the Bank reasonably believes to be an Authorized Representative without the need of independent investigation, the Borrowers hereby indemnifying the Bank from any liability or loss ensuing from so acting. 
 Section 2.4. Change of Law. Notwithstanding any other provisions of this Agreement or any Note, if at any time the Bank shall determine that any
change in applicable laws, treaties or regulations, or in the interpretation thereof, makes it unlawful for the Bank to create, continue or maintain any LIBOR Portion, it shall promptly so notify the Borrowers and the obligation of the Bank to
create, continue or maintain any such LIBOR Portion under this Agreement shall be suspended until it is no longer unlawful for the Bank to create, continue or maintain such LIBOR Portion. If the continued maintenance of any such LIBOR Portion is
unlawful, the Borrowers shall prepay on demand to the Bank the outstanding principal amount of the affected LIBOR Portion together with all interest accrued thereon and all other amounts payable to the Bank with respect thereto under this Agreement;
provided, however, the Borrowers may elect to convert the principal amount of the affected LIBOR Portion into the relevant Base Rate Portion hereunder, subject to the terms and conditions of this Agreement (including, without limitation,
Section 2.7 hereof). 
 Section 2.5. Unavailability of Deposits or Inability to Ascertain Adjusted LIBOR. Notwithstanding any other
provision of this Agreement or any Note, if the Bank shall determine prior to the commencement of any Interest Period that deposits in the amount of any LIBOR Portion scheduled to be outstanding during such Interest Period are not readily available
to the Bank in the relevant market or, by reason of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining Adjusted LIBOR, then the Bank shall promptly give notice thereof to the Borrowers and the
obligations of the Bank to create, continue or effect by conversion any such LIBOR Portion in such amount and for such Interest Period shall be suspended until deposits in such amount and for the Interest Period selected by the Borrowers shall again
be readily available in the relevant market and adequate and reasonable means exist for ascertaining Adjusted LIBOR. 
 Section 2.6.
Taxes and Increased Costs. With respect to any LIBOR Portion, if the Bank shall determine that any change in any applicable law, treaty, regulation or guideline (including, without limitation, Regulation D of the Board of Governors of the Federal
Reserve System), or any new law, treaty, regulation or guideline, or any interpretation of any of the foregoing, by any governmental authority charged with the administration thereof or any central bank or other fiscal, monetary or other authority
having jurisdiction over the Bank or its lending branch or the LIBOR Portions contemplated by this Agreement (whether or not having the force of law), shall: 
 (i) impose, increase or deem applicable any reserve, special deposit or similar requirement against assets held by, or deposits in or for
the account of, or loans by, or any other acquisition of funds or disbursements by, the Bank which is not in any instance already accounted for in computing the interest rate applicable to such LIBOR Portion; 
  

 5 

 (ii) subject the Bank, any LIBOR Portion or any Note to the extent it evidences a LIBOR
Portion to any tax (including, without limitation, any United States interest equalization tax or similar tax however named applicable to the acquisition or holding of debt obligations and any interest or penalties with respect thereto), duty,
charge, stamp tax, fee, deduction or withholding in respect of this Agreement, any LIBOR Portion or any Note to the extent it evidences a LIBOR Portion, except such taxes as may be measured by the overall net income or gross receipts of the Bank or
its lending branches and imposed by the jurisdiction, or any political subdivision or taxing authority thereof, in which the Bank’s principal executive office or its lending branch is located; 
 (iii) change the basis of taxation of payments of principal and interest due from the Borrowers to the Bank hereunder or under any Note to
the extent it evidences any LIBOR Portion (other than by a change in taxation of the overall net income or gross receipts of the Bank); or 
 (iv) impose on the Bank any penalty with respect to the foregoing or any other condition regarding this Agreement, any LIBOR Portion or its disbursement, or any Note to the extent it evidences any LIBOR Portion;

 and the Bank shall determine that the result of any of the foregoing is to increase the cost (whether by incurring a cost or adding to a cost) to the Bank
of creating or maintaining any LIBOR Portion hereunder or to reduce the amount of principal or interest received or receivable by the Bank (without benefit of, or credit for, any prorations, exemption, credits or other offsets available under any
such laws, treaties, regulations, guidelines or interpretations thereof), then the Borrowers shall jointly and severally pay on demand to the Bank from time to time as specified by the Bank such additional amounts as the Bank shall reasonably
determine are sufficient to compensate and indemnify it for such increased cost or reduced amount incurred not more than one hundred and twenty (120) days prior to the date of such notice. If the Bank makes such a claim for compensation, it
shall provide to the Borrowers a certificate setting forth the computation of the increased cost or reduced amount as a result of any event mentioned herein in reasonable detail and such certificate shall be conclusive if reasonably determined.

 Section 2.7. Funding Indemnity. In the event the Bank shall incur any loss, cost or expense (including, without limitation, any loss,
cost or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired or contracted to be acquired by the Bank to fund or maintain any LIBOR Portion or the relending or reinvesting of such deposits or other funds
or amounts paid or prepaid to the Bank) as a result of: 
 (i) any payment of a LIBOR Portion on a date other than the last
day of the then applicable Interest Period for any reason, whether before or after a Default or an Event of Default, and whether or not such payment is required by any provision of this Agreement; or 
 (ii) any failure by the Borrowers to create, borrow, continue or effect by conversion a LIBOR Portion on the date specified in a notice
given pursuant to this Agreement; 
 then, upon the demand of the Bank, the Borrowers shall jointly and severally pay to the Bank such amount as will
reimburse the Bank for such loss, cost, or expense. If the Bank requests such a reimbursement, it shall provide to the Borrowers a certificate setting forth the computation of the loss, cost or expense giving rise to the request for reimbursement in
reasonable detail and such certificate shall be conclusive if reasonably determined. 
  

 6 

 Section 2.8. Lending Branch. The Bank may, at its option, elect to make, fund or maintain Portions
of the Loans hereunder at such of its branches or offices as the Bank may from time to time elect; provided, however, if such designation by the Bank results in any request for compensation pursuant to Section 2.4 or 2.6 hereof, the Bank shall
use reasonable efforts to designate a different branch or office that would eliminate or reduce the amounts payable pursuant to Sections 2.4 and/or 2.6. 
 Section 2.9. Discretion of Bank as to Manner of Funding. Notwithstanding any other provision of this Agreement to the contrary, the Bank shall be entitled to fund and maintain its funding of all or any part of
the Notes in any manner it sees fit; it being understood, however, that for the purposes of this Agreement all determinations hereunder (including, without limitation, determinations under Sections 2.5, 2.6, and 2.7 hereof) shall be made as if the
Bank had actually funded and maintained each LIBOR Portion during each Interest Period applicable thereto through the purchase of deposits in the relevant market in the amount of such LIBOR Portion, having a maturity corresponding to such Interest
Period, and bearing an interest rate equal to the LIBOR for such Interest Period. 
 Section 2.10. Interest Act Canada. For the purpose
of complying with the Interest Act (Canada), it is expressly stated that: 
 (i) where interest is calculated pursuant hereto
at a rate based on a 360 day or a 365 day period, the yearly rate or percentage of interest to which such rate is equivalent is such rate multiplied by the actual number of days in the year (365 or 366, as the case may be) divided by 360 or 365 as
the case may be; and 
 (ii) the rates of interest and the Applicable Margin and other rates specified in this Agreement are
nominal rates and not effective rates or yields and the parties hereto acknowledge that there is a material distinction between the nominal and effective rates of interest, that they are capable of making the calculations necessary to compare such
rates and that the principle of deemed reinvestment of interest shall not apply to any calculations of interest hereunder. 
 Section 2.11.
Withholding Tax Gross-Up. Each of the Borrowers and the Guarantors shall comply in a timely manner with each of the following provisions: 
 (i) all amounts due hereunder, whether for principal, interest, or otherwise, shall be paid in full without set-off, withholding or deduction of any kind or nature whatsoever except only as and to the extent provided
by subsection (ii). 
 (ii) if a Borrower or a Guarantor is required by law to make any deduction or withholding of any taxes
from any payment due hereunder (other than taxes imposed on or measured by the net income of the Bank by the jurisdiction under the laws of which the Bank is organized, is resident or carries on business, collectively, the “Excluded
Taxes”), then the amount payable shall be increased to such amount which, after deduction from such increased amount of all such taxes required to be withheld or deducted therefrom, will not be less than the amount due and payable hereunder had
no such deduction or withholding been required. 
 (iii) if a Borrower or a Guarantor makes any payment owing to the Bank
hereunder in respect of which it is required by law to make any deduction or withholding of any taxes (other than Excluded Taxes), such party shall pay the full amount to be deducted or withheld to the relevant governmental authority within the time
allowed for such payment under applicable law and shall promptly deliver to the Bank, a receipt issued by such governmental authority or a statement of such party confirming the payment to such governmental authority of all amounts so required to be
deducted or withheld from such payment. 
  

 7 

 Section 2.12. Currency Conversion Clause. Payments hereunder to the Bank shall be made in the same
currency as is required to be paid by the Borrowers to the Bank in respect of the Obligations (the “Required Currency”). If a Borrower or Guarantor makes payment to the Bank hereunder in any other currency (the “Payment
Currency”), such payment shall constitute satisfaction of the said liability of the Borrower or Guarantor hereunder only to the extent that the Bank is able to purchase Required Currency with the amount of the Payment Currency received from the
Borrower or Guarantor on the date of receipt, in accordance with the Bank’s normal practice; and the Borrower and the Guarantors shall remain liable to the Bank for any deficiency together with interest thereon payable pursuant to this

above, the Borrowers further jointly and severally agree to pay to the Bank such issuing, processing, and transaction fees and charges as the Bank from time to time customarily imposes in connection with any issuance, amendment, cancellation,

pay to the Bank charges for audits of the Collateral performed by the Bank or its agents or representatives in such amounts as the Bank may from time to time request (the Bank acknowledging and agreeing that such charges shall be computed in the
same manner as the Bank at the time customarily uses for the assessment of charges for similar collateral audits); provided, however, that in the absence of any Default or Event of Default, the Borrowers shall not be required to pay the Bank for

any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank (or any of
its branches) with any request or directive regarding capital adequacy (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the Bank’s
capital as a consequence of its obligations hereunder or for the credit which is the subject matter hereof to a level below that which the Bank could have achieved but for such adoption, change or compliance (taking into consideration the
Bank’s policies with respect to liquidity and capital adequacy) by an amount deemed by the Bank to be material, then from time to time, within fifteen (15) days after demand by the Bank, the Borrowers shall jointly and severally pay to the
Bank such additional amount or amounts reasonably determined by the Bank as will compensate the Bank for such reduction which were incurred not more than one hundred and twenty (120) days prior to the date of such demand.

Bank, as liquidated damages for the loss of bargain and not as a penalty, in an amount equal to 1.0% of the Revolving Credit Commitment being terminated if termination occurs at any time prior to December 29, 2007. If termination of the
Revolving Credit Commitment occurs at any time on or after December 29, 2007, no prepayment premium shall be payable with respect to the Revolving Credit hereunder.

percentage set forth below of the principal amount so prepaid on the Term Note:

 Section 3.5. Place and Application of Payments and Collections. (a) All payments of principal,
interest, fees, and all other Obligations payable hereunder and under the other Loan Documents shall be made to the Bank at its office at 111 West Monroe Street, Chicago, Illinois (or at such other place as the Bank may specify). Payments received
by the Bank after 2:00 p.m. (Chicago time) shall be deemed received as of the opening of business on the next Business Day. All such payments shall be made in lawful money of the United States of America, in immediately available funds at the place
of payment, without set-off or counterclaim and without reduction for, and free from, any and all present or future taxes, levies, imposts, duties, fees, charges, deductions, withholdings, restrictions or conditions of any nature imposed by any
government or any political subdivision or taxing authority thereof (but excluding any taxes imposed on or measured by the net income of the Bank). Unless the Borrowers otherwise direct, principal payments shall be applied first to the applicable
Base Rate Portion until payment in full thereof, with any balance applied to the applicable LIBOR Portions in the order in which their Interest Periods expire. 
 (b) All payments made by the Borrowers on the Obligations, and all proceeds of Collateral received by the Bank, shall in each case, upon receipt by the Bank, be applied by the Bank to the Obligations then due and
payable, with any balance of such proceeds not applied to the Obligations to be held by the Bank as collateral security for the Obligations except as otherwise set forth herein. Prior to the occurrence of a Default or Event of Default, except as
otherwise specifically provided for herein or directed by the Borrowers, all payments made by the Borrowers on the Obligations, and all proceeds of Collateral received by the Bank, shall in each case be applied by the Bank against the outstanding
Obligations as follows: 
 (i) first, to any outstanding fees, charges, and expenses then due the Bank; 
 (ii) second, to outstanding interest charges then due in respect of the Obligations; 
 (iii) third, to any scheduled principal installment then due in respect of the Term Loan; 
 (iv) fourth, to the outstanding principal balance of the Revolving Loans and reimbursement obligations in respect of amounts drawn under
Letters of Credit; and 
 (v) finally, to be made available to the Borrowers for working capital purposes or invested by the
Borrowers as permitted by Section 8.9 hereof. 
 Except as otherwise specifically provided for herein, the Borrowers hereby irrevocably waive the right
to direct the application of payments and collections at any time received by the Bank from or on behalf of the Borrowers, and the Borrowers hereby irrevocably agree that the Bank shall have the continuing exclusive right to apply and reapply any
and all such payments and collections received at any time by the Bank against the Obligations in such manner as the Bank may deem advisable; provided, however, if no Default or Event of Default has occurred and is continuing, the Bank shall apply
any and all such payments and collections received by the Bank against the Obligations in the manner directed by the Borrowers. 
 (c) The
Borrowers hereby irrevocably authorize the Bank to charge any Borrower’s deposit accounts maintained with the Bank for the amounts from time to time necessary to pay any then due Obligations; provided that the Borrowers acknowledge and agree
that the Bank shall be under no obligation to do so and the Bank shall incur no liability to the Borrowers or any other Person for the Bank’s failure to do so.

 Section 3.6. Voluntary Prepayments. In addition to such prepayments of the outstanding Obligations
as a result from the application of proceeds of Collateral contemplated by Section 3.5 above, the Borrowers shall have the right to prepay the Notes as follows: 
 (i) Base Rate Portion. The Borrowers may prepay in whole or in part (but if in part, then in an amount not less than $10,000) the Base
Rate Portion of any Note at any time upon notice to the Bank prior to 11:00 a.m. (Chicago time) on the date of such prepayment. 
 (ii) LIBOR Portions. The Borrowers may prepay any LIBOR Portion of any Note in whole or in part (but if in part, then in an amount not less than $100,000 or such greater amount which is an integral multiple of $100,000), upon 3 Business
Days’ prior notice to the Bank (which notice shall be irrevocable once given and must be received by the Bank no later than 11:00 a.m. (Chicago time) on the third Business Day preceding the date of such prepayment, and shall specify the
principal amount to be repaid); provided, however, that (x) after giving effect to any such prepayment in part, the outstanding principal amount of each remaining LIBOR Portion of the relevant Note shall not be less than $500,000 or such
greater amount which is an integral multiple of $100,000 and (y) any such prepayment shall be accompanied by payment of any amounts due to the Bank under Section 2.7 hereof. 
 Any such prepayment shall be effected by payment of the principal amount to be prepaid and, in the case of the Term Note, accrued interest thereon to the date of prepayment. Any such prepayment shall be accompanied by
any prepayment premium due under Section 3.4 hereof. 
 Section 3.7. Mandatory Prepayments. (a) Borrowing Base. The Borrowers
covenant and agree that if at any time the sum of the then unpaid principal balance of the Revolving Loans plus the then outstanding amount of Letters of Credit shall be in excess of the Borrowing Base as then determined and computed, the Borrowers
shall immediately and without notice or demand pay over the amount of the excess to the Bank as and for a mandatory prepayment on such Obligations, with each such prepayment first to be applied to the Revolving Loans until payment in full thereof
with any remaining balance to be held by the Bank as collateral security for the Obligations owing under the Applications, until the Borrower is back in compliance with the Borrowing Base limitations. 
 (b) Fixed Asset Value. The Borrowers covenant and agree that if at any time the outstanding principal balance of the Term Note shall be in excess of 80%
of the loan value of Eligible Equipment as then determined and computed by the Bank plus 70% of the appraised fair market value of the Borrowers real estate, the Borrowers shall immediately and without notice or demand pay over the amount of the
excess to the Bank as and for a mandatory prepayment on the Term Note. Any such prepayment shall be applied to the outstanding principal balance of the Term Note in the inverse order of maturity until paid in full. For purposes hereof, the loan
value of Eligible Equipment shall be the current orderly liquidation value for such equipment as reasonably determined by the Bank in accordance with its customary standards and practices for commercial loans. Any prepayment of the Term Note made
pursuant to this Section 3.7(b) shall not be subject to the prepayment premium contained in Section 3.4 of this Agreement. 
 (c) Asset
Sales. The Borrowers covenant and agree that all proceeds derived from the sale or disposition (whether voluntary or involuntary), or on account of damage or destruction, of Collateral consisting of real estate, furniture, fixtures, equipment or
other fixed assets of the Borrowers shall be paid over to the Bank as and for a mandatory prepayment on the Term Note; provided that if at the time of receipt no amount is outstanding under the Term Note or the amount received is in excess of the
amount necessary to prepay the Term Note in full, 

  

 11 

 
then such prepayment or excess (as appropriate) shall be applied to the Revolving Note (or held by the Bank as collateral security for the Borrowers’
Obligations under the Applications if the Revolving Loans have been prepaid in full but Letters of Credit remain outstanding), subject to the Borrowers’ right to reborrow amounts so applied against the Revolving Credit in accordance with the
terms and conditions hereof; provided, however, that (i) the foregoing provision shall be inapplicable to proceeds received by the Bank under the Collateral Documents if and so long as the Borrowers have, pursuant to the Collateral Documents,
requested that the same be held by the Bank and disbursed for the restoration, repair or replacement of the property in respect of which such proceeds were received and (ii) no prepayment shall be required with respect to up to $100,000 of net
proceeds (i.e., gross proceeds net of out-of-pocket expenses incurred in effecting the sale or other disposition) received in any calendar year from the sale or other disposition of personal property Collateral which is worn out, obsolete or, in the
good faith judgment of the Borrowers, no longer necessary to the efficient conduct of its business as then conducted. Any such prepayment applied to the outstanding principal balance of the Term Note shall be applied to the several installments
thereof in the inverse order of its maturity. Any prepayment of the Term Note made pursuant to this Section 3.7(c) shall not be subject to the prepayment premium contained in Section 3.4 of this Agreement. 
 (d) Revolver Termination. The Borrowers covenant and agree that concurrently with any termination of the Revolving Credit Commitment in whole (including
any such termination on the Termination Date), the Borrowers shall prepay the Term Note in full accompanied by (i) any prepayment premium required pursuant to Section 3.4 hereof, except to the extent not required by Section 3.7
hereof, (ii) accrued and unpaid interest on the Notes to the date of prepayment, and (iii) all other amounts due on the Obligations. 
 Section 3.8. Computation of Obligations Outstanding. For the purpose of calculating the aggregate principal balance of Obligations outstanding hereunder, Obligations shall be deemed to be paid on the date payments or collections, as
the case may be, are applied by the Bank to such Obligations; provided, however, for purposes of calculating interest payable by the Borrowers on the Loans and on any other interest-bearing Obligations under this Agreement, any payment or
collection, as the case may be, other than payments or collections received by the Bank in immediately available funds, shall be deemed to be applied in accordance with Section 3.5 hereof to the Loans or other interest-bearing Obligations one
(1) Business Day after receipt of such payment or collection by the Bank. Notwithstanding the foregoing, if any item presented for collection by the Bank is not honored, the Bank may reverse any provisional credit which has been given for the
item and make appropriate adjustments to the amount of interest and principal otherwise due hereunder. 
 Section 3.9. Notations. The
amount and date of each Loan and the amount and due date of each payment of principal and interest thereon, the status of all amounts as constituting part of the relevant Base Rate Portion or a LIBOR Portion, and, in the case of any LIBOR Portion,
the rates of interest and Interest Periods applicable to such Portion, shall be recorded by the Bank on its books and records or, at its option, recorded on a schedule to the applicable Note, and the amount of principal and interest, status, rates
and Interest Periods so recorded or endorsed by the Bank shall be prima facie evidence in any court or other proceeding brought to enforce the relevant Note of the principal amount remaining unpaid thereon, the status of the Loan or Loans evidenced
thereby, and the interest rates and Interest Periods applicable thereto; provided that the failure of the Bank to record any of the foregoing shall not limit or otherwise affect the obligation of the Borrowers to repay the principal amount owing on
such Note together with accrued interest thereon.

account to constitute a special restricted account. Any proceeds of Collateral received by any Borrower or any Subsidiary shall be held by it in trust for the Bank in the same form in which received, shall not be commingled with any assets of the
Borrowers or any Subsidiary, and shall be delivered immediately to the Bank (together with any necessary endorsements thereto) for deposit into such account. The Borrowers acknowledge that the Bank has (and is hereby granted to the extent it does

U.S. Guarantor of the principal of or interest on or any other amount payable in respect of the Obligations, Funds Transfer and Deposit Account Liability, or Hedging Liability; or 
 (h) any other act or omission to act or delay of any kind by the Bank or any of its Affiliates or any other Person or any other
circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the obligations of any U.S. Guarantor under this Section 10. 
 Section 10.3. Discharge Only upon Payment in Full; Reinstatement in Certain Circumstances. Each U.S. Guarantor’s obligations under this
Section 10 shall remain in full force and effect until the commitments hereunder are terminated, all Letters of Credit have expired, and the principal of and interest on the Notes and all other amounts payable by the Borrowers and the
Subsidiaries under this Agreement and all other Loan Documents and, if then outstanding and unpaid, all Hedging Liability and Funds Transfer and Deposit Account Liability shall have been paid in full. If at any time any payment of the principal of
or interest on any Note or any reimbursement obligation under any Application or any other amount payable in respect of the Obligation, Funds Transfer and Deposit Account Liability or Hedging Liability by any Borrower or any U.S. Guarantor under the
Loan Documents or any other agreement is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of any Borrower or of any U.S. Guarantor, or otherwise, each remaining U.S. Guarantor’s obligations
under this Section 10 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time. 
 Section 10.4. Subrogation. Each U.S. Guarantor agrees it will not exercise any rights which it may acquire by way of subrogation by any payment made hereunder, or otherwise, until all the Obligations, Hedging
Liability, and Funds Transfer and Deposit Account Liability shall have been paid in full subsequent to the termination of all the commitments to extend credit to the Borrowers hereunder and expiration of all Letters of Credit. If any amount shall be
paid to a U.S. Guarantor on account of such subrogation rights at any time prior to the later of (x) the payment in full of the Obligations, Hedging Liability, and Funds Transfer and Deposit Account Liability and all other amounts payable by
the Borrowers and their Subsidiaries hereunder and the other Loan Documents and (y) the termination of the commitments to extend credit to the Borrower hereunder and expiration of all Letters of Credit, such amount shall be held in trust for
the benefit of the Bank and its Affiliates and shall forthwith be paid to the Bank or be credited and applied upon the Obligations, Hedging Liability, 

  

 46 

 
and Funds Transfer and Deposit Account Liability, whether matured or unmatured, as the Bank shall determine. 
 Section 10.5. Waivers. Each U.S. Guarantor irrevocably waives acceptance hereof, presentment, demand, protest, and any notice not provided for
herein, as well as any requirement that at any time any action be taken by the Bank or any other Person against the Borrower, another guarantor, or any other Person. 
 Section 10.6. Limit on Recovery. Notwithstanding any other provision hereof, the right of recovery against each U.S. Guarantor under this Section 10 shall not exceed $1.00 less than the lowest amount which would
render such U.S. Guarantor’s obligations under this Section 10 void or voidable under applicable law, including, without limitation, fraudulent conveyance law. 
 Section 10.7. Stay of Acceleration. If acceleration of the time for payment of any amount payable by any Borrower or any other obligor under this Agreement or any other Loan Document, or under any agreement
establishing Hedging Liability or Funds Transfer and Deposit Account Liability, is stayed upon the insolvency, bankruptcy or reorganization of such Borrower or such other obligor, all such amounts otherwise subject to acceleration under the terms of
this Agreement or the other Loan Documents, or under any agreement establishing Hedging Liability or Funds Transfer and Deposit Account Liability, shall nonetheless be payable by the remaining U.S. Guarantors hereunder forthwith on demand by the
Bank. 
 Section 10.8. Benefit to Guarantors. All of the Guarantors are engaged in related businesses and integrated to such an extent
that the financial strength and flexibility of each U.S. Guarantor has a direct impact on the success of each other Guarantor. Each U.S. Guarantor will derive substantial direct and indirect benefit from the extension of credit hereunder.

 Section 10.9. Guarantor Covenants. Each Guarantor shall take such action as any Borrower is required by this Agreement to cause such
Guarantor to take, and shall refrain from taking such action as any Borrower is required by this Agreement to prohibit such Guarantor from taking. 
 SECTION
11. MISCELLANEOUS. 
 Section 11.1. Non-Business Days. Except as otherwise set forth herein, if any payment hereunder becomes due and
payable on a day which is not a Business Day, the due date of such payment shall be extended to the next succeeding Business Day on which date such payment shall be due and payable. In the case of any payment of principal falling due on a day which
is not a Business Day, interest on such principal amount shall continue to accrue during such extension at the rate per annum then in effect, which accrued amount shall be due and payable on the next scheduled date for the payment of interest.

 Section 11.2. No Waiver, Cumulative Remedies. No delay or failure on the part of the Bank in the exercise of any power or right shall
operate as a waiver thereof or as an acquiescence in any default, nor shall any single or partial exercise of any power or right preclude any other or further exercise thereof or the exercise of any other power or right. The rights and remedies
hereunder of the Bank are cumulative to, and not exclusive of, any rights or remedies which it would otherwise have. 
 Section 11.3.
Amendments, Etc. No amendment, modification, termination or waiver of any provision of this Agreement or of any other Loan Document, nor consent to any departure by any Borrower or any Guarantor therefrom, shall in any event be effective unless the
same shall be in writing and signed by the Bank. No notice to or demand on any Borrower or any Guarantor in any case shall entitle such Borrower or such Guarantor to any other or further notice or demand in similar or other circumstances.

  

 47

demand the costs and expenses of the Bank incurred in connection with the negotiation, preparation, execution and delivery of this Agreement and the other Loan Documents and the other instruments and documents to be delivered thereunder, and in
connection with the recording and filing of any of the foregoing as well as in connection with lien searches from time to time obtained by the Bank in its administration of the credit facilities provided for herein, and in connection with the
transactions contemplated hereby or thereby, and in connection with any consents hereunder and any waivers or amendments hereto or thereto, including the reasonable fees and expenses of counsel for the Bank, with respect to all of the foregoing
(whether or not the transactions contemplated hereby are consummated). The Borrowers further jointly and severally agree to pay to the Bank or any other holder of the Obligations, Funds Transfer and Deposit Account Liability, and Hedging Liability
all costs and expenses (including court costs and attorneys’ reasonable fees), if any, incurred or paid by the Bank or any other holder of the Obligations, Funds Transfer and Deposit Account Liability, and Hedging Liability in connection with
any Default or Event of Default or in connection with the enforcement of this Agreement or any other Loan Document or any other instrument or document delivered thereunder. The Borrowers further jointly and severally agree to indemnify the Bank, and
any security trustee, and their respective directors, officers and employees, against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor,
whether or not the indemnified person is a party thereto) which any of them may pay or incur arising out of or relating to any Loan Document or any of the transactions contemplated thereby or the direct or indirect application or proposed
application of the proceeds of any extension of credit made available hereunder, other than those which arise from the gross negligence or willful misconduct of the party claiming indemnification. The Borrowers, upon demand by the Bank at any time,
shall reimburse the Bank for any reasonable legal or other expenses incurred in connection with investigating or defending against any of the foregoing except if the same is directly due to the gross negligence or willful misconduct of the party to
be indemnified. The obligations of the Borrowers under this Section shall survive the termination of this Agreement. 
 (b) The Borrowers
unconditionally jointly and severally agree to forever indemnify, defend and hold harmless, and covenants not to sue for any claim for contribution against, the Bank for any damages, costs, loss or expense, including without limitation, response,
remedial or removal costs, arising out of any of the following: (i) any presence, release, threatened release or disposal of any hazardous or toxic substance or petroleum by any Borrower or any Subsidiary or otherwise occurring on or with
respect to their Property, (ii) the operation or violation of any environmental law, whether federal, state, or local, and any regulations promulgated thereunder, by any Borrower or any Subsidiary or otherwise occurring on or with respect to
their Property, (iii) any claim for personal injury or property damage in connection with any Borrower or any Subsidiary or otherwise occurring on or with respect to their Property, and (iv) the inaccuracy or breach of any environmental
representation, warranty or covenant by any Borrower or any Subsidiary made herein or in any mortgage, deed of trust, security agreement, or any other instrument or document evidencing or securing any indebtedness, obligations, or liabilities of any
Borrower or any Subsidiary owing to the Bank or setting forth terms and conditions applicable thereto or otherwise relating thereto, except for damages arising from the Bank’s willful misconduct or gross negligence. This indemnification shall
survive the payment and satisfaction of all obligations owing to the Bank and the termination of this Agreement. This indemnification shall be binding upon the successors and assigns of the Borrowers and shall inure to the benefit of Bank and its
directors, officers, employees, agents, and collateral trustees, and their successors and assigns.

documentary, stamp or similar taxes payable in respect of this Agreement or any other Loan Document, including interest and penalties, in the event any such taxes are assessed, irrespective of when such assessment is made and whether or not any
credit is then in use or available hereunder. 
 Section 11.6. Survival of Representations; Survival of Indemnities. All representations
and warranties made herein or in any of the other Loan Documents or in certificates given pursuant hereto or thereto shall survive the execution and delivery of this Agreement and the other Loan Documents, and shall continue in full force and effect

 Section 11.8. Participations. The Bank may grant participations in its
extensions of credit hereunder to any other bank or other lending institution (a “Participant”), provided that (a) no Participant shall thereby acquire any direct rights under this Agreement or the other Loan Documents and (b) no
sale of such a participation in extensions of credit hereunder shall in any manner relieve the Bank of its obligations hereunder. 
 Section 11.9. Construction. The provisions of this Agreement relating to Subsidiaries shall only apply during such times as any Borrower has one or more Subsidiaries. Nothing contained herein shall be deemed or construed to permit any
act or omission which is prohibited by the terms of any of the other Loan Documents, the covenants and agreements contained herein being in addition to and not in substitution for the covenants and agreements contained in the other Loan Documents.

 Section 11.11. Severability of Provisions. Any provision of this Agreement which is prohibited or

provision shall require the payment or permit the collection of any amount of interest in excess of the maximum amount of interest permitted by applicable law to be charged for the use or detention, or forbearance in the collection, of all or any
portion of the Loans or any other Obligations (“Excess Interest”). If any Excess Interest is provided for, or is adjudicated to be provided for, herein or in any other Loan Document, then in such event (a) the provisions of this
Section shall govern and control, (b) neither the Borrowers nor any guarantor or endorser shall be obligated to pay any Excess Interest, (c) any Excess Interest that the Bank may have received hereunder shall, at the sole option of the Bank in
its discretion, be (i) applied as a credit against the then outstanding principal amount of the Obligations and accrued and unpaid interest thereon (not to exceed the maximum amount permitted by applicable law), (ii) refunded to the
Borrowers or (iii) any combination of the foregoing, (d) the interest rate payable hereunder or under any other Loan Document shall be automatically subject to reduction to the maximum lawful contract rate allowed under applicable usury
laws (the “Maximum Rate”), and this Agreement and the other Loan Documents shall be deemed to have been, and hereby shall be, reformed and modified to reflect such reduction in the relevant interest rate, and (e) neither the Borrowers
nor any guarantor or endorser shall have any action against the Bank for any damages whatsoever arising out of the payment or collection of any Excess Interest. Notwithstanding the foregoing, if for any period of time interest on any of the
Obligations is calculated at the Maximum Rate rather than the applicable rate under the relevant Loan Document, and thereafter such applicable rate becomes less than the Maximum Rate, the rate of interest payable on the Obligations shall remain at
the Maximum Rate until the Bank has received the amount of interest which it would have received during such period on the Obligations had the rate of interest not been limited to the Maximum Rate during such period. 
 Section 11.15. Binding Nature, Governing Law, Etc. This Agreement shall be binding upon the Borrowers and the Guarantors and their successors and
assigns, and shall inure to the benefit of the Bank and its Affiliates and the benefit of their successors and assigns, including any subsequent holder of the Obligations. The Borrowers and the Guarantors may not assign their rights hereunder
without the written consent of the Bank. This Agreement constitutes the entire understanding of the parties with respect to the subject matter hereof and any prior agreements, whether written or oral, with respect thereto are superseded hereby. THIS
AGREEMENT AND THE RIGHTS AND DUTIES OF THE PARTIES HERETO SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF ILLINOIS WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. 
 Section 11.16. Submission to Jurisdiction; Waiver of Jury Trial. The Borrowers and the Guarantors hereby submits to the nonexclusive jurisdiction of the
United States District Court for the Northern District of Illinois and of any Illinois State court sitting in the City of Chicago for purposes of all legal proceedings arising out of or relating to this Agreement, the other Loan Documents or the
transactions contemplated hereby or thereby. The Borrowers and 

  

 50 

 
the Guarantors irrevocably waive, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of the venue of any
such proceeding brought in such a court and any claim that any such proceeding brought in such a court has been brought in an inconvenient forum. THE BORROWERS, THE GUARANTORS, AND THE BANK EACH HEREBY IRREVOCABLY WAIVE ANY AND ALL RIGHT TO TRIAL BY
JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED THEREBY. 
 Section 11.17.
Confidentiality. The Bank, the Borrowers and the Subsidiaries agree that each will maintain the confidentiality of the terms and provisions of this Agreement and the information and materials delivered to them or made available to them or made

confidentiality), (d) required to be disclosed by applicable law or by any governmental authority, (e) disclosed to the parties’ attorneys and accountants, or (f) disclosed to a potential participant or assignee of the
