SECTION 2 COMMITMENTS OF THE LENDERS; BORROWING, CONVERSION AND LETTER OF CREDIT PROCEDURES.

2.1 Commitments. On and subject to the terms and conditions of this Agreement, each of the Lenders, severally and for itself alone, agrees to
make loans to, and to issue or participate in letters of credit for the account of, the Borrowers as follows:

2.1.1 Revolving Loan
Commitment. Each Lender with a Revolving Loan Commitment agrees to make loans on a revolving basis (Revolving Loans) from time to time until the Termination Date in such Lenders Pro Rata Share of such aggregate amounts
as the Borrowers may request from all Lenders; provided that the Revolving Outstandings will not at any time exceed Revolving Loan Availability (less the amount of any Swing Line Loans outstanding at such time).

2.1.2 Term Loan Commitments. Each Lender with an Equipment Term Loan Commitment agrees to make a loan to the Borrowers (each such loan, an
Equipment Term Loan) on the Closing Date in such Lenders Pro Rata Share of the Equipment Term Loan Commitment. Each Lender with a Real Estate Term Loan Commitment agrees to make a loan to the Borrowers (each such loan, a

---

2.1.3 L/C Commitment. Subject to Section 2.3.1, the Issuing Lender agrees to issue
letters of credit, in each case containing such terms and conditions as are permitted by this Agreement and are reasonably satisfactory to the Issuing Lender (each, a Letter of Credit), at the request of and for the account of the
Borrowers from time to time before the scheduled Termination Date and, as more fully set forth in Section 2.3.2, each Lender agrees to purchase a participation in each such Letter of Credit; provided that (a) the aggregate
Stated Amount of all Letters of Credit shall not at any time exceed $5,000,000 and (b) the Revolving Outstandings shall not at any time exceed Revolving Loan Availability (less the amount of any Swing Line Loans outstanding at such time).

2.2 Loan Procedures.

2.2.1 Various Types of Loans. Each Revolving Loan shall be, and each Term Loan may be divided into tranches which are, either a Base Rate Loan or a LIBOR Loan (each, a type of Loan), as the Borrowers shall specify
in the related notice of borrowing or conversion pursuant to Section 2.2.2 or 2.2.3. LIBOR Loans having the same Interest Period which expire on the same day are sometimes called a Group or collectively
Groups. Base Rate Loans and LIBOR Loans may be outstanding at the same time, provided that not more than five different Groups of LIBOR Loans shall be outstanding at any one time. All borrowings, conversions and repayments
of Revolving Loans shall be effected so that each Lender will have a ratable share (according to its Pro Rata Share) of all types and Groups of Loans. Notwithstanding the foregoing or any other provision of this Agreement, the Borrowers may not
select any Interest Period for a LIBOR Loan which is longer than one month until the earlier of (x) 90 days after the Closing Date and (y) the date that the Administrative Agent notifies the Borrowers that it has completed its primary
syndication of the Loans and the Commitments.

2.2.2 Borrowing Procedures. The Borrowers shall give written notice (each such written
notice, a Notice of Borrowing) substantially in the form of Exhibit E or telephonic notice (followed immediately by a Notice of Borrowing) to the Administrative Agent of each proposed borrowing not later than (a) in
the case of a Base Rate borrowing, 11:00 A.M., Chicago time, on the proposed date of such borrowing, and (b) in the case of a LIBOR borrowing, 11:00 A.M., Chicago time, at least two Business Days prior to the proposed date of such
borrowing. Each such notice shall be effective upon receipt by the Administrative Agent, shall be irrevocable, and shall specify the date, amount and type of borrowing and, in the case of a LIBOR borrowing, the initial Interest Period therefor.
Promptly upon receipt of such notice, the Administrative Agent shall advise each Lender thereof. Not later than 1:00 P.M., Chicago time, on the date of a proposed borrowing, each Lender shall provide the Administrative Agent at the office specified
by the Administrative Agent with immediately available funds covering such Lenders



23



---

Pro Rata Share of such borrowing and, so long as the Administrative Agent has not received written notice
that the conditions precedent set forth in Section 12 with respect to such borrowing have not been satisfied, the Administrative Agent shall pay over the funds received by the Administrative Agent to the Borrowers on the requested
borrowing date. Each borrowing shall be on a Business Day. Each Base Rate borrowing shall be in an aggregate amount of at least $50,000 and an integral multiple of $10,000, and each LIBOR borrowing shall be in an aggregate amount of at least
$1,000,000 and an integral multiple of at least $100,000.

2.2.3 Conversion and Continuation Procedures. (a) Subject to
Section 2.2.1, the Borrowers may, upon irrevocable written notice to the Administrative Agent in accordance with clause (b) below:

(i) elect, as of any Business Day, to convert any Loans (or any part thereof in an aggregate amount not less than $1,000,000 or a higher integral multiple of $100,000) into Loans of the other type; or

(ii) elect, as of the last day of the applicable Interest Period, to continue any LIBOR Loans having Interest Periods expiring on such day (or any part
thereof in an aggregate amount not less than $1,000,000 or a higher integral multiple of $100,000) for a new Interest Period; provided that after giving effect to any prepayment, conversion or continuation, the aggregate principal amount of
each Group of LIBOR Loans shall be at least $1,000,000 and an integral multiple of $100,000.

(b) The Borrowers shall give written notice
(each such written notice, a Notice of Conversion/Continuation) substantially in the form of Exhibit F or telephonic notice (followed immediately by a Notice of Conversion/Continuation) to the Administrative Agent of each
proposed conversion or continuation not later than (i) in the case of conversion into Base Rate Loans, 11:00 A.M., Chicago time, on the proposed date of such conversion and (ii) in the case of conversion into or continuation of LIBOR
Loans, 11:00 A.M., Chicago time, at least two Business Days prior to the proposed date of such conversion or continuation, specifying in each case:

(A) the proposed date of conversion or continuation;

(B) the aggregate amount of Loans to be converted or continued;

(C) the type of Loans resulting from the proposed conversion or continuation; and

(D) in the case of conversion into, or continuation of, LIBOR Loans, the duration of the requested Interest Period therefor.

(c) If upon the expiration of any Interest Period applicable to LIBOR Loans, the Borrowers have failed to select timely a new Interest Period to be
applicable to such LIBOR Loans, the Borrowers shall be deemed to have elected to convert such LIBOR Loans into Base Rate Loans effective on the last day of such Interest Period.



24



---

(d) The Administrative Agent will promptly notify each Lender of its receipt of a notice of conversion or
continuation pursuant to this Section 2.2.3 or, if no timely notice is provided by the Borrowers, of the details of any automatic conversion.

(e) Any conversion of a LIBOR Loan on a day other than the last day of an Interest Period therefor shall be subject to Section 8.4.

2.2.4 Swing Line Facility.

(a) The
Administrative Agent shall notify the Swing Line Lender upon the Administrative Agents receipt of any Notice of Borrowing. Subject to the terms and conditions hereof, the Swing Line Lender may, in its sole discretion, make available from time
to time until the Termination Date advances (each, a Swing Line Loan) in accordance with any such notice, notwithstanding that after making a requested Swing Line Loan, the sum of the Swing Line Lenders Pro Rata Share of the
Revolving Outstanding and all outstanding Swing Line Loans, may exceed the Swing Line Lenders Pro Rata Share of the Revolving Commitment. The provisions of this Section 2.2.4 shall not relieve Lenders of their obligations to make
Revolving Loans under Section 2.1.1; provided that if the Swing Line Lender makes a Swing Line Loan pursuant to any such notice, such Swing Line Loan shall be in lieu of any Revolving Loan that otherwise may be made by the Lenders
pursuant to such notice. The aggregate amount of Swing Line Loans outstanding shall not exceed at any time Swing Line Availability. Until the Termination Date, the Borrowers may from time to time borrow, repay and reborrow under this
Section 2.2.4. Each Swing Line Loan shall be made pursuant to a Notice of Borrowing delivered by the Borrowers to the Administrative Agent in accordance with Section 2.2.2. Any such notice must be given no later than 2:00
P.M., Chicago time, on the Business Day of the proposed Swing Line Loan. Unless the Swing Line Lender has received at least one Business Days prior written notice from the Required Lenders instructing it not to make a Swing Line Loan, the
Swing Line Lender shall, notwithstanding the failure of any condition precedent set forth in Section 12.2, be entitled to fund that Swing Line Loan, and to have such Lender make Revolving Loans in accordance with
Section 2.2.4(c) or purchase participating interests in accordance with Section 2.2.4(d). Notwithstanding any other provision of this Agreement or the other Loan Documents, each Swing Line Loan shall constitute a Base Rate
Loan. The Borrowers shall repay the aggregate outstanding principal amount of each Swing Line Loan upon demand therefor by the Administrative Agent.

(b) The entire unpaid balance of each Swing Line Loan and all other noncontingent Obligations shall be immediately due and payable in full in immediately available funds on the Termination Date if not sooner paid in
full.

(c) The Swing Line Lender, at any time and from time to time no less frequently than once weekly, shall on behalf of the Borrowers
(and the Borrowers hereby irrevocably authorize the Swing Line Lender to so act on their behalf) request each Lender with a Revolving Commitment (including the Swing Line Lender) to make a Revolving Loan to the Borrowers (which shall be a Base Rate
Loan) in an amount equal to that Lenders Pro Rata Share of the



25



---

principal amount of all Swing Line Loans (the Refunded Swing Line Loan) outstanding on the date such
notice is given. Unless any of the events described in Section 13.1.4 has occurred (in which event the procedures of Section 2.2.4(d) shall apply) and regardless of whether the conditions precedent set forth in this Agreement
to the making of a Revolving Loan are then satisfied, each Lender shall disburse directly to the Administrative Agent, its Pro Rata Share on behalf of the Swing Line Lender, prior to 2:00 P.M., Chicago time, in immediately available funds on the
date that notice is given (provided that such notice is given by 12:00 p.m., Chicago time, on such date). The proceeds of those Revolving Loans shall be immediately paid to the Swing Line Lender and applied to repay the Refunded Swing Line
Loan.

(d) If, prior to refunding a Swing Line Loan with a Revolving Loan pursuant to Section 2.2.4(c), one of the events
described in Section 13.1.4 has occurred, then, subject to the provisions of Section 2.2.4(e) below, each Lender shall, on the date such Revolving Loan was to have been made for the benefit of the Borrowers, purchase from the
Swing Line Lender an undivided participation interest in the Swing Line Loan in an amount equal to its Pro Rata Share of such Swing Line Loan. Upon request, each Lender shall promptly transfer to the Swing Line Lender, in immediately available
funds, the amount of its participation interest.

(e) Each Lenders obligation to make Revolving Loans in accordance with
Section 2.2.4(c) and to purchase participation interests in accordance with Section 2.2.4(d) shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim,
recoupment, defense or other right that such Lender may have against the Swing Line Lender, the Borrowers or any other Person for any reason whatsoever; (ii) the occurrence or continuance of any Unmatured Event of Default or Event of Default;
(iii) any inability of the Borrowers to satisfy the conditions precedent to borrowing set forth in this Agreement at any time or (iv) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing. If
and to the extent any Lender shall not have made such amount available to the Administrative Agent or the Swing Line Lender, as applicable, by 2:00 P.M., Chicago time, the amount required pursuant to Sections 2.2.4(c) or 2.2.4(d), as the case
may be, on the Business Day on which such Lender receives notice from the Administrative Agent of such payment or disbursement (it being understood that any such notice received after noon, Chicago time, on any Business Day shall be deemed to have
been received on the next following Business Day), such Lender agrees to pay interest on such amount to the Administrative Agent for the Swing Line Lenders account forthwith on demand, for each day from the date such amount was to have been
delivered to the Administrative Agent to the date such amount is paid, at a rate per annum equal to (a) for the first three days after demand, the Federal Funds Rate from time to time in effect and (b) thereafter, the Base Rate from time
to time in effect.

2.3 Letter of Credit Procedures.

2.3.1 L/C Applications. The Borrowers shall execute and deliver to the Issuing Lender the Letter of Credit Agreement from time to time in effect. The Borrowers shall give notice to the Administrative Agent and
the Issuing Lender of the proposed issuance of each Letter of Credit on a Business Day which is at least three Business Days (or such lesser number of days as the Administrative Agent and the Issuing Lender shall agree in any particular instance in
their sole



26



---

discretion) prior to the proposed date of issuance of such Letter of Credit. Each such notice shall be
accompanied by an L/C Application, duly executed by the Borrowers and in all respects satisfactory to the Administrative Agent and the Issuing Lender, together with such other documentation as the Administrative Agent or the Issuing Lender may
request in support thereof, it being understood that each L/C Application shall specify, among other things, the date on which the proposed Letter of Credit is to be issued, the expiration date of such Letter of Credit (which shall not be later than
the scheduled Termination Date (unless such Letter of Credit is Cash Collateralized)) and whether such Letter of Credit is to be transferable in whole or in part. Any Letter of Credit outstanding after the scheduled Termination Date which is Cash
Collateralized for the benefit of the Issuing Lender shall be the sole responsibility of the Issuing Lender. So long as the Issuing Lender has not received written notice that the conditions precedent set forth in Section 12 with respect
to the issuance of such Letter of Credit have not been satisfied, the Issuing Lender shall issue such Letter of Credit on the requested issuance date. The Issuing Lender shall promptly advise the Administrative Agent of the issuance of each Letter
of Credit and of any amendment thereto, extension thereof or event or circumstance changing the amount available for drawing thereunder. In the event of any inconsistency between the terms of the Letter of Credit Agreement, any L/C Application and
the terms of this Agreement, the terms of this Agreement shall control.

2.3.2 Participations in Letters of Credit. Concurrently with
the issuance of each Letter of Credit, the Issuing Lender shall be deemed to have sold and transferred to each Lender with a Revolving Loan Commitment, and each such Lender shall be deemed irrevocably and unconditionally to have purchased and
received from the Issuing Lender, without recourse or warranty, an undivided interest and participation, to the extent of such Lenders Pro Rata Share, in such Letter of Credit and the Borrowers reimbursement obligations with respect
thereto. If the Borrowers do not pay any reimbursement obligation when due, the Borrowers shall be deemed to have immediately requested that the Lenders make a Revolving Loan which is a Base Rate Loan in a principal amount equal to such
reimbursement obligations. The Administrative Agent shall promptly notify such Lenders of such deemed request and, without the necessity of compliance with the requirements of Section 2.2.2, Section 12.2 or otherwise such
Lender shall make available to the Administrative Agent its Pro Rata Share of such Loan. The proceeds of such Loan shall be paid over by the Administrative Agent to the Issuing Lender for the account of the Borrowers in satisfaction of such
reimbursement obligations. For the purposes of this Agreement, the unparticipated portion of each Letter of Credit shall be deemed to be the Issuing Lenders participation therein. The Issuing Lender hereby agrees, upon request of
the Administrative Agent or any Lender, to deliver to the Administrative Agent or such Lender a list of all outstanding Letters of Credit issued by the Issuing Lender, together with such information related thereto as the Administrative Agent or
such Lender may reasonably request.



27



---

2.3.3 Reimbursement Obligations. (a) The Borrowers jointly and severally hereby
unconditionally and irrevocably agree to reimburse the Issuing Lender for each payment or disbursement made by the Issuing Lender under any Letter of Credit honoring any demand for payment made by the beneficiary thereunder, in each case on the date
that such payment or disbursement is made. Any amount not reimbursed on the date of such payment or disbursement shall bear interest from the date of such payment or disbursement to the date that the Issuing Lender is reimbursed by the Borrowers
therefor, payable on demand, at a rate per annum equal to the Base Rate from time to time in effect plus the Base Rate Margin from time to time in effect plus, beginning on the third Business Day after receipt of notice from the
Issuing Lender of such payment or disbursement, 2%. The Issuing Lender shall notify the Borrowers and the Administrative Agent whenever any demand for payment is made under any Letter of Credit by the beneficiary thereunder; provided that the
failure of the Issuing Lender to so notify the Borrowers or the Administrative Agent shall not affect the rights of the Issuing Lender or the Lenders in any manner whatsoever.

(b) The Borrowers reimbursement obligations hereunder shall be joint and several, irrevocable and unconditional under all circumstances, including
(a) any lack of validity or enforceability of any Letter of Credit, this Agreement or any other Loan Document, (b) the existence of any claim, set-off, defense or other right which any MPW Company may have at any time against a beneficiary
named in a Letter of Credit, any transferee of any Letter of Credit (or any Person for whom any such transferee may be acting), the Administrative Agent, the Issuing Lender, any Lender or any other Person, whether in connection with any Letter of
Credit, this Agreement, any other Loan Document, the transactions contemplated herein or any unrelated transactions (including any underlying transaction between any MPW Company and the beneficiary named in any Letter of Credit), (c) the
validity, sufficiency or genuineness of any document which the Issuing Lender has determined complies on its face with the terms of the applicable Letter of Credit, even if such document should later prove to have been forged, fraudulent, invalid or
insufficient in any respect or any statement therein shall have been untrue or inaccurate in any respect, or (d) the surrender or impairment of any security for the performance or observance of any of the terms hereof. Without limiting the
foregoing, no action or omission whatsoever by the Administrative Agent or any Lender (excluding any Lender in its capacity as the Issuing Lender) under or in connection with any Letter of Credit or any related matters shall result in any liability
of the Administrative Agent or any Lender to the Borrowers, or relieve the Borrowers of any of their obligations hereunder to any such Person.

2.3.4 Funding by Lenders to Issuing Lender. If the Issuing Lender makes any payment or disbursement under any Letter of Credit and (a) the Borrowers have not reimbursed the Issuing Lender in full for such payment or disbursement
by 11:00 A.M., Chicago time, on the date of such payment or disbursement, (b) a Revolving Loan may not be made in accordance with Section 2.3.2 or (c) any reimbursement received by the Issuing Lender from the Borrowers is or
must be returned or rescinded upon or during any bankruptcy or reorganization of any Borrower or otherwise, each other Lender with a Revolving Loan Commitment shall be obligated to pay to the Administrative Agent for the account of the Issuing
Lender, in full or partial payment of the purchase price of its participation



28



---

in such Letter of Credit, its Pro Rata Share of such payment or disbursement (but no such payment shall
diminish the obligations of the Borrowers under Section 2.3.3), and, upon notice from the Issuing Lender, the Administrative Agent shall promptly notify each other Lender thereof. Each other Lender irrevocably and unconditionally agrees
to so pay to the Administrative Agent in immediately available funds for the Issuing Lenders account the amount of such other Lenders Pro Rata Share of such payment or disbursement. If and to the extent any Lender shall not have made
such amount available to the Administrative Agent by 2:00 P.M., Chicago time, on the Business Day on which such Lender receives notice from the Administrative Agent of such payment or disbursement (it being understood that any such notice received
after noon, Chicago time, on any Business Day shall be deemed to have been received on the next following Business Day), such Lender agrees to pay interest on such amount to the Administrative Agent for the Issuing Lenders account forthwith on
demand, for each day from the date such amount was to have been delivered to the Administrative Agent to the date such amount is paid, at a rate per annum equal to (a) for the first three days after demand, the Federal Funds Rate from time to
time in effect and (b) thereafter, the Base Rate from time to time in effect. Any Lenders failure to make available to the Administrative Agent its Pro Rata Share of any such payment or disbursement shall not relieve any other Lender of
its obligation hereunder to make available to the Administrative Agent such other Lenders Pro Rata Share of such payment, but no Lender shall be responsible for the failure of any other Lender to make available to the Administrative Agent such
other Lenders Pro Rata Share of any such payment or disbursement.

2.4 Commitments Several. The failure of any Lender to make
a requested Loan on any date shall not relieve any other Lender of its obligation (if any) to make a Loan on such date, but no Lender shall be responsible for the failure of any other Lender to make any Loan to be made by such other Lender.

2.5 Certain Conditions. Except as otherwise provided in Sections 2.2.4 and 2.3.4 of this Agreement, no Lender shall have an
obligation to make any Loan, or to permit the continuation of or any conversion into any LIBOR Loan, and the Issuing Lender shall not have any obligation to issue any Letter of Credit, if an Event of Default or Unmatured Event of Default exists.

SECTION 3 EVIDENCING OF LOANS.

3.1 Notes. The Loans of each Lender shall be evidenced by a Note, with appropriate insertions, payable to the order of such Lender in a face principal amount equal to the sum of such Lenders Revolving Loan Commitment plus the
principal amount of such Lenders Term Loans.

3.2 Recordkeeping. The Administrative Agent, on behalf of each Lender, shall
record in its records, the date and amount of each Loan made by each Lender, each repayment or conversion thereof and, in the case of each LIBOR Loan, the dates on which each Interest Period for such Loan shall begin and end. The aggregate unpaid
principal amount so recorded shall be



29



---

rebuttably presumptive evidence of the principal amount of the Loans owing and unpaid. The failure to so record any such
amount or any error in so recording any such amount shall not, however, limit or otherwise affect the Obligations of the Borrowers hereunder or under any Note to repay the principal amount of the Loans hereunder, together with all interest accruing
thereon.

SECTION 4 INTEREST.

4.1 Interest Rates. The Borrowers jointly and severally promise to pay interest on the unpaid principal amount of each Loan for the period commencing on the date of such Loan until such Loan is paid in full as follows:

(a) at all times while such Loan is a Base Rate Loan, at a rate per annum equal to the sum of the Base Rate from time to time in effect plus the Base Rate
Margin from time to time in effect; and

(b) at all times while such Loan is a LIBOR Loan, at a rate per annum equal to the sum of the
LIBOR Rate applicable to each Interest Period for such Loan plus the LIBOR Margin from time to time in effect;

provided that at any time an Event
of Default exists, unless the Required Lenders otherwise consent, the interest rate applicable to each Loan shall be increased by 2% (and, in the case of Obligations not bearing interest, such Obligations shall bear interest at the Base Rate
applicable to Revolving Loans plus 2%), provided further that such increase may thereafter be rescinded by the Required Lenders, notwithstanding Section 15.1. Notwithstanding the foregoing, upon the occurrence of an Event
of Default under Sections 13.1.1 or 13.1.4, such increase shall occur automatically.

4.2 Interest Payment Dates.
Accrued interest on each Base Rate Loan shall be payable in arrears on the last day of each calendar month and at maturity. Accrued interest on each LIBOR Loan shall be payable on the last day of each Interest Period relating to such Loan (and, in
the case of a LIBOR Loan with an Interest Period in excess of three months, on the three-month anniversary of the first day of such Interest Period), upon a prepayment of such Loan, and at maturity. After maturity, and at any time an Event of
Default exists, accrued interest on all Loans shall be payable on demand.

4.3 Setting and Notice of LIBOR Rates. The applicable
LIBOR Rate for each Interest Period shall be determined by the Administrative Agent, and notice thereof shall be given by the Administrative Agent promptly to the Borrowers and each Lender. Each determination of the applicable LIBOR Rate by the
Administrative Agent shall be conclusive and binding upon the parties hereto, in the absence of demonstrable error. The Administrative Agent shall, upon written request of the Borrowers or any Lender, deliver to the Borrowers or such Lender a
statement showing the computations used by the Administrative Agent in determining any applicable LIBOR Rate hereunder.

4.4 Computation
of Interest. Interest shall be computed for the actual number of days elapsed on the basis of a year of (a) 360 days for interest calculated at the LIBOR Rate and (b) 365/366 days for interest calculated at the Base Rate. The
applicable interest rate for each Base Rate Loan shall change simultaneously with each change in the Base Rate.

SECTION 5 FEES.

5.1 Non-Use Fee. The Borrowers jointly and severally agree to pay to the Administrative Agent for the account of each Lender a non-use fee, for the period from the Closing Date to the Termination Date, at the
Non-Use Fee Rate in effect from time to time of such Lenders Pro Rata Share (as adjusted from time to time) of the unused amount of the Revolving Commitment. For purposes of calculating usage under this Section, the Revolving Commitment shall
be deemed used to the extent of Revolving Outstandings. Such non-use fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date for any period then ending for which such non-use fee shall not have previously
been paid. The non-use fee shall be computed for the actual number of days elapsed on the basis of a year of 360 days. For the avoidance of doubt, Outstanding Swingline Loans will not constitute utilization of the Revolving Credit Facility for
purposes of calculating this fee.

5.2 Letter of Credit Fees. (a) The Borrowers jointly and severally agree to pay to the
Administrative Agent for the account of each Lender a letter of credit fee for each Letter of Credit equal to the L/C Fee Rate in effect from time to time of such Lenders Pro Rata Share (as adjusted from time to time) of the undrawn amount of
such Letter of Credit (computed for the actual number of days elapsed on the basis of a year of 360 days); provided that, unless the Required Lenders otherwise consent, the rate applicable to each Letter of Credit shall be increased by 2% at
any time that an Event of Default exists. Such letter of credit fee shall be payable in arrears on the last day of each calendar quarter and on the Termination Date (or such later date on which such Letter of Credit expires or is terminated) for the
period from the date of the issuance of each Letter of Credit (or the last day on which the letter of credit fee was paid with respect thereto) to the date such payment is due or, if earlier, the date on which such Letter of Credit expired or was
terminated.

(b) In addition, with respect to each Letter of Credit, the Borrowers jointly and severally agree to pay to the Issuing
Lender, for its own account, (i) such fees and expenses as the Issuing Lender customarily requires in connection with the issuance, negotiation, processing and/or administration of letters of credit in similar situations and (ii) a letter
of credit fronting fee in the amount and at the times agreed to by the Borrowers and the Issuing Lender.

5.3 Administrative
Agents Fees. The Borrowers jointly and severally agree to pay to the Administrative Agent such agents fees as are mutually agreed to from time to time by the Borrowers and the Administrative Agent including the fees set forth in the
Agent Fee Letter.

arising with respect to the Letters of Credit.

6.1.2 Mandatory Reductions of Revolving Commitment. On the date of any Mandatory

Unless sooner paid in full, the outstanding principal balance of the Real Estate Term Loan shall be paid
in full on the Real Estate Term Loan Maturity Date. Notwithstanding the foregoing, (a) if the Real Estate Term Loan Commitment is less than the maximum set forth in the definition thereof, the principal amount required to be paid on each date
set forth above that has not yet lapsed shall be reduced by the product of (i) the principal amount otherwise required to be paid multiplied by (ii) a fraction equal to the amount by which the Real Estate Term Loan Commitment is less than
the maximum set forth in the definition divided by the aggregate remaining principal balance of the Real Estate Term Loan and (b) if the Real Estate Term Loan Commitment increases from time to time by operation of the definition thereof,
the principal amount required to be paid on each date set forth above that has not yet lapsed shall be increased by the product of (i) the principal amount otherwise required to be paid multiplied by (ii) a fraction equal to the amount by
which principal payments prior to the date of such increase were, in the aggregate, less than the principal payments scheduled to be repaid in the table above divided by the aggregate remaining principal balance of the Real Estate Term Loan.

SECTION 7 MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

7.1 Making of Payments. All payments of principal or interest on the Notes, and of all fees, shall be made by the Borrowers to the Administrative Agent in immediately available funds at the office specified by
the Administrative Agent not later than noon, Chicago time, on the date due; and funds received after that hour shall be deemed to have been received by the Administrative Agent on the following Business Day. The Administrative Agent is hereby
authorized to charge the account of any Borrower maintained with the Administrative Agent for each payment of principal, interest or other amounts due hereunder. The Administrative Agent shall promptly remit to each Lender its share of all such
payments received in collected funds by the Administrative Agent for the account of such Lender. All payments under Section 8.1 shall be made by the Borrowers directly to the Lender entitled thereto without setoff, counterclaim or other
defense.

7.2 Application of Certain Payments. So long as no Unmatured Event of Default or Event of Default has occurred and is
continuing, (a) payments matching specific scheduled payments then due shall be applied to those scheduled payments and (b) voluntary and mandatory prepayments shall be applied as set forth in Sections 6.2 and 6.3. After the
occurrence and during the continuance of an Unmatured Event of Default or Event of Default, all amounts collected or received by the Administrative Agent or any Lender as proceeds from the sale of, or other realization upon, all or any part of the
Collateral shall be applied as set forth in the Guaranty and Collateral Agreement. Concurrently with each remittance to any Lender of its share of any such payment, the Administrative Agent shall advise such Lender as to the application of such
payment.



35



---

7.3 Due Date Extension. If any payment of principal or interest with respect to any of the Loans,
or of any fees, falls due on a day which is not a Business Day, then such due date shall be extended to the immediately following Business Day (unless, in the case of a LIBOR Loan, such immediately following Business Day is the first Business Day of
a calendar month, in which case such due date shall be the immediately preceding Business Day) and, in the case of principal, additional interest shall accrue and be payable for the period of any such extension.

7.4 Setoff. Each Borrower, agrees that the Administrative Agent and each Lender have all rights of set-off and bankers lien provided by
applicable law, and in addition thereto, each Borrower, agrees that at any time any Event of Default exists, the Administrative Agent and each Lender may apply to the payment of any Obligations of the Borrowers hereunder, whether or not then due,
any and all balances, credits, deposits, accounts or moneys of the Borrowers then or thereafter with the Administrative Agent or such Lender.

7.5 Proration of Payments. If any Lender shall obtain any payment or other recovery (whether voluntary, involuntary, by application of offset or otherwise, on account of (a) principal of or interest on any Loan, but excluding
(i) any payment pursuant to Section 8.7 or 15.6 and (ii) payments of interest on any Affected Loan) or (b) its participation in any Letter of Credit) in excess of its applicable Pro Rata Share of payments and other
recoveries obtained by all Lenders on account of principal of and interest on the Loans (or such participation) then held by them, then such Lender shall purchase from the other Lenders such participations in the Loans (or sub-participations in
Letters of Credit) held by them as shall be necessary to cause such purchasing Lender to share the excess payment or other recovery ratably with each of them; provided that if all or any portion of the excess payment or other recovery is
thereafter recovered from such purchasing Lender, the purchase shall be rescinded and the purchase price restored to the extent of such recovery.

7.6 Taxes.

(a) All payments made by the Borrowers hereunder or under any Loan Documents shall be made without setoff,
counterclaim, or other defense. To the extent permitted by applicable law, all payments hereunder or under the Loan Documents (including any payment of principal, interest, or fees) to, or for the benefit, of any person shall be made by the
Borrowers free and clear of and without deduction or withholding for, or account of, any Taxes now or hereinafter imposed by any taxing authority.

(b) If any Borrower makes any payment hereunder or under any Loan Document in respect of which it is required by applicable law to deduct or withhold any Taxes, the Borrowers shall increase the payment hereunder or under any such Loan
Document such that after the reduction for the amount of Taxes withheld (and any taxes withheld or imposed with respect to the additional payments required under this Section 7.6(b)), the amount paid to the Lenders or the Administrative
Agent equals the amount that was payable hereunder or under any such Loan Document without regard to this Section 7.6(b). To the extent any Borrower withholds any Taxes on payments hereunder or under any Loan Document, the Borrowers
shall pay the full amount deducted to the relevant taxing authority within the time allowed for payment under applicable law and shall deliver to the Administrative Agent within 30 days after it has made payment to such authority a receipt issued by
such authority (or other evidence satisfactory to the Administrative Agent) evidencing the payment of all amounts so required to be deducted or withheld from such payment.



36



---

(c) If any Lender or the Administrative Agent is required by law to make any payments of any Taxes on or
in relation to any amounts received or receivable hereunder or under any other Loan Document, or any Tax is assessed against a Lender or the Administrative Agent with respect to amounts received or receivable hereunder or under any other Loan
Document, the Borrowers will indemnify such person against (i) such Tax (and any reasonable counsel fees and expenses associated with such Tax) and (ii) any taxes imposed as a result of the receipt of the payment under this
Section 7.6(c). A certificate prepared in good faith as to the amount of such payment by such Lender or the Administrative Agent shall, absent manifest error, be final, conclusive, and binding on all parties.

(d) (i) To the extent permitted by applicable law, each Lender that is not a United States person within the meaning of Code
Section 7701(a)(30) (a Non-U.S. Participant) shall deliver to the Borrowers and the Administrative Agent on or prior to the Closing Date (or in the case of a Lender that is an Assignee, on the date of such assignment to such
Lender) two accurate and complete original signed copies of IRS Form W-8BEN, W-8ECI, or W-8IMY (or any successor or other applicable form prescribed by the IRS) certifying to such Lenders entitlement to a complete exemption from, or a reduced
rate in, United States withholding tax on interest payments to be made hereunder or any Loan. If a Lender that is a Non-U.S. Participant is claiming a complete exemption from withholding on interest pursuant to Code Sections 871(h) or 881(c), the
Lender shall deliver (along with two accurate and complete original signed copies of IRS Form W-8BEN) a certificate in form and substance reasonably acceptable to Administrative Agent (any such certificate, a Withholding
Certificate). In addition, each Lender that is a Non-U.S. Participant agrees that from time to time after the Closing Date, (or in the case of a Lender that is an Assignee, after the date of the assignment to such Lender), when a lapse in
time (or change in circumstances occurs) renders the prior certificates hereunder obsolete or inaccurate in any material respect, such Lender shall, to the extent permitted under applicable law, deliver to the Borrowers and the Administrative Agent
two new and accurate and complete original signed copies of an IRS Form W-8BEN, W-8ECI, or W-8IMY (or any successor or other applicable forms prescribed by the IRS), and if applicable, a new Withholding Certificate, to confirm or establish the
entitlement of such Lender or the Administrative Agent to an exemption from, or reduction in, United States withholding tax on interest payments to be made hereunder or any Loan.

(ii) Each Lender that is not a Non-U.S. Participant (other than any such Lender which is taxed as a corporation for U.S. federal income tax purposes)
shall provide two properly completed and duly executed copies of IRS Form W-9 (or any successor or other applicable form) to the Borrowers and the Administrative Agent certifying that such Lender is exempt from United States backup withholding tax.
To the extent that a form provided pursuant to this Section 7.6(d)(ii) is rendered obsolete or inaccurate in any material respects as result of change in circumstances with respect to the status of a Lender, such Lender shall, to the
extent permitted by applicable law, deliver to the Borrowers and the Administrative Agent revised forms necessary to confirm or establish the entitlement to such Lenders or Agents exemption from United States backup withholding tax.



37



---

(iii) The Borrowers shall not be required to pay additional amounts to a Lender, or indemnify any Lender,
under this Section 7.6 to the extent that such obligations would not have arisen but for the failure of such Lender to comply with Section 7.6(d).

(iv) Each Lender agrees to indemnify the Administrative Agent and hold the Administrative Agent harmless for the full amount of any and all present or future Taxes and related liabilities (including penalties,
interest, additions to tax and expenses, and any Taxes imposed by any jurisdiction on amounts payable to the Administrative Agent under this Section 7.6) which are imposed on or with respect to principal, interest or fees payable to such
Lender hereunder and which are not paid by the Borrowers pursuant to this Section 7.6, whether or not such Taxes or related liabilities were correctly or legally asserted. This indemnification shall be made within 30 days from the date
the Administrative Agent makes written demand therefor.

SECTION 8 INCREASED COSTS; SPECIAL PROVISIONS FOR LIBOR LOANS.

8.1 Increased Costs. (a) If, after the date hereof, the adoption of, or any change in, any applicable law, rule or regulation, or any change
in the interpretation or administration of any applicable law, rule or regulation by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender with any
request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) shall impose, modify or deem applicable any reserve (including any reserve imposed by the FRB, but excluding any reserve
included in the determination of the LIBOR Rate pursuant to Section 4), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by any Lender; or (ii) shall impose on any
Lender any other condition affecting its LIBOR Loans, its Note or its obligation to make LIBOR Loans; and the result of anything described in clauses (i) and (ii) above is to increase the cost to (or to impose a cost on) such Lender (or
any LIBOR Office of such Lender) of making or maintaining any LIBOR Loan, or to reduce the amount of any sum received or receivable by such Lender (or its LIBOR Office) under this Agreement or under its Note with respect thereto, then upon demand by
such Lender (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount thereof in reasonable detail, a copy of which shall be furnished to the Administrative Agent), the Borrowers shall
pay directly to such Lender such additional amount as will compensate such Lender for such increased cost or such reduction, so long as such amounts have accrued on or after the day which is 180 days prior to the date on which such Lender first made
demand therefor.

(b) If any Lender shall reasonably determine that any change in, or the adoption or phase-in of, any applicable law, rule
or regulation regarding capital adequacy, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or the compliance by
any Lender or any Person controlling such Lender 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 such Lenders or such controlling Persons capital as a consequence of such Lenders obligations hereunder or under any Letter of Credit to a level below that which such Lender or such controlling Person could have
achieved but for such change, adoption, phase-in or compliance (taking into



38



---

consideration such Lenders or such controlling Persons policies with respect to capital adequacy) by an
amount deemed by such Lender or such controlling Person to be material, then from time to time, upon demand by such Lender (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount
thereof in reasonable detail, a copy of which shall be furnished to the Administrative Agent), the Borrowers shall pay to such Lender such additional amount as will compensate such Lender or such controlling Person for such reduction so long as such
amounts have accrued on or after the day which is 180 days prior to the date on which such Lender first made demand therefor.

8.2 Basis
for Determining Interest Rate Inadequate or Unfair. If:

(a) the Administrative Agent reasonably determines (which determination shall
be binding and conclusive on the Borrowers) that by reason of circumstances affecting the interbank LIBOR market adequate and reasonable means do not exist for ascertaining the applicable LIBOR Rate; or

(b) the Required Lenders advise the Administrative Agent that the LIBOR Rate as determined by the Administrative Agent will not adequately and fairly
reflect the cost to such Lenders of maintaining or funding LIBOR Loans for such Interest Period (taking into account any amount to which such Lenders may be entitled under Section 8.1) or that the making or funding of LIBOR Loans has
become impracticable as a result of an event occurring after the date of this Agreement which in the opinion of such Lenders materially affects such Loans;

then the Administrative Agent shall promptly notify the other parties thereof and, so long as such circumstances shall continue, (i) no Lender shall be under any obligation to make or convert any Base Rate Loans into LIBOR Loans
and (ii) on the last day of the current Interest Period for each LIBOR Loan, such Loan shall, unless then repaid in full, automatically convert to a Base Rate Loan.

8.3 Changes in Law Rendering LIBOR Loans Unlawful. If any change in, or the adoption of any new, law or regulation, or any change in the interpretation of any applicable law or regulation by any governmental or
other regulatory body charged with the administration thereof, should make it (or in the good faith judgment of any Lender cause a substantial question as to whether it is) unlawful for any Lender to make, maintain or fund LIBOR Loans, then such
Lender shall promptly notify each of the other parties hereto and, so long as such circumstances shall continue, (a) such Lender shall have no obligation to make or convert any Base Rate Loan into a LIBOR Loan (but shall make Base Rate Loans
concurrently with the making of or conversion of Base Rate Loans into LIBOR Loans by the Lenders which are not so affected, in each case in an amount equal to the amount of LIBOR Loans which would be made or converted into by such Lender at such
time in the absence of such circumstances) and (b) on the last day of the current Interest Period for each LIBOR Loan of such Lender (or, in any event, on such earlier date as may be required by the relevant law, regulation or interpretation),
such LIBOR Loan shall, unless then repaid in full, automatically convert to a Base Rate Loan. Each Base Rate Loan made by a Lender which, but for the circumstances described in the foregoing sentence, would be a LIBOR Loan (an Affected
Loan) shall remain outstanding for the period corresponding to the Group of LIBOR Loans of which such Affected Loan would be a part absent such circumstances.

8.4 Funding Losses. The Borrowers hereby jointly and severally agree that upon demand by any
Lender (which demand shall be accompanied by a statement setting forth the basis for the amount being claimed, a copy of which shall be furnished to the Administrative Agent), the Borrowers will indemnify such Lender against any net loss or expense
which such Lender may sustain or incur (including any net loss or expense incurred by reason of the liquidation or reemployment of deposits or other funds acquired by such Lender to fund or maintain any LIBOR Loan), as reasonably determined by such
Lender, as a result of (a) any payment, prepayment or conversion of any LIBOR Loan of such Lender on a date other than the last day of an Interest Period for such Loan (including any conversion pursuant to Section 8.3) or
(b) any failure of the Borrowers to borrow, convert or continue any Loan on a date specified therefor in a notice of borrowing, conversion or continuation pursuant to this Agreement. For this purpose, all notices to the Administrative Agent
pursuant to this Agreement shall be deemed to be irrevocable.

8.5 Right of Lenders to Fund through Other Offices. Each Lender may,
if it so elects, fulfill its commitment as to any LIBOR Loan by causing a foreign branch or Affiliate of such Lender to make such Loan; provided that in such event for the purposes of this Agreement such Loan shall be deemed to have been made
by such Lender and the obligation of the Borrowers to repay such Loan shall nevertheless be to such Lender and shall be deemed held by it, to the extent of such Loan, for the account of such branch or Affiliate.

8.6 Discretion of Lenders as to Manner of Funding. Notwithstanding any provision of this Agreement to the contrary, each Lender shall be entitled
to fund and maintain its funding of all or any part of its Loans in any manner it sees fit, it being understood, however, that for the purposes of this Agreement all determinations hereunder shall be made as if such Lender had actually funded and
maintained each LIBOR Loan during each Interest Period for such Loan through the purchase of deposits having a maturity corresponding to such Interest Period and bearing an interest rate equal to the LIBOR Rate for such Interest Period.

8.7 Mitigation of Circumstances; Replacement of Lenders. (a) Each Lender shall promptly notify the Borrowers and the Administrative Agent
of any event of which it has knowledge which will result in, and will use reasonable commercial efforts available to it (and not, in such Lenders sole judgment, otherwise disadvantageous to such Lender) to mitigate or avoid, (i) any
obligation by the Borrowers to pay any amount pursuant to Sections 7.6 or 8.1 or (ii) the occurrence of any circumstances described in Sections 8.2 or 8.3 (and, if any Lender has given notice of any such event
described in clause (i) or (ii) above and thereafter such event ceases to exist, such Lender shall promptly so notify the Borrowers and the Administrative Agent). Without limiting the foregoing, each Lender will designate a different
funding office if such designation will avoid (or reduce the cost to the Borrowers of) any event described in clause (i) or (ii) above and such designation will not, in such Lenders sole judgment, be otherwise disadvantageous to such
Lender.

(b) If the Borrowers become obligated to pay additional amounts to any Lender pursuant to Sections 7.6 or 8.1, or
any Lender gives notice of the occurrence of any circumstances described in Sections 8.2 or 8.3, the Borrowers may designate another bank which is acceptable to the Administrative Agent and the Issuing Lender in their reasonable
discretion (such other bank being called a Replacement Lender) to purchase the Loans of such Lender



40



---

and such Lenders rights hereunder, without recourse to or warranty by, or expense to, such Lender, for a purchase
price equal to the outstanding principal amount of the Loans payable to such Lender plus any accrued but unpaid interest on such Loans and all accrued but unpaid fees owed to such Lender and any other amounts payable to such Lender under this
Agreement, and to assume all the obligations of such Lender hereunder, and, upon such purchase and assumption (pursuant to an Assignment Agreement), such Lender shall no longer be a party hereto or have any rights hereunder (other than rights with
respect to indemnities and similar rights applicable to such Lender prior to the date of such purchase and assumption) and shall be relieved from all obligations to the Borrowers hereunder, and the Replacement Lender shall succeed to the rights and
obligations of such Lender hereunder.

8.8 Conclusiveness of Statements; Survival of Provisions. Determinations and statements of
any Lender pursuant to Sections 8.1, 8.2, 8.3 or 8.4 shall be conclusive absent demonstrable error. Lenders may use reasonable averaging and attribution methods in determining compensation under Sections 8.1 and
8.4, and the provisions of such Sections shall survive repayment of the Obligations, cancellation of any Notes, expiration or termination of the Letters of Credit and termination of this Agreement.

Section 302 of ERISA or the terms of any Pension Plan has occurred with respect to any Pension Plan, sufficient to give rise to a Lien under Section 302(f) of ERISA, or otherwise to have a Material Adverse Effect. There are no pending or,
to the knowledge of MPW Companies, threatened, claims, actions, investigations or lawsuits against any Pension Plan, any fiduciary of any Pension Plan, or Company or other any member of the Controlled Group with respect to a Pension Plan or a
Multiemployer Pension Plan which could reasonably be expected to have a Material Adverse Effect. Neither the Company nor any other member of the Controlled Group has engaged in any prohibited transaction (as defined in Section 4975 of the Code
or Section 406 of ERISA) in connection with any Pension Plan or Multiemployer Pension Plan which would subject that Person to any material liability. Within the past five years, neither the Company nor any other member of the Controlled Group
has engaged in a transaction which resulted in a Pension Plan with an Unfunded Liability being transferred out of the Controlled Group, which could reasonably be expected to have a Material Adverse Effect. No Termination Event has occurred or is
reasonably expected to occur with respect to any Pension Plan, which could reasonably be expected to have a Material Adverse Effect.

(b)

applicable law; neither the Company nor any other member of the Controlled Group has withdrawn or partially withdrawn from any Multiemployer Pension Plan, incurred any withdrawal liability with respect to any such plan or received notice of any
claim or demand for withdrawal liability or partial withdrawal liability from any such plan, and no condition has occurred which, if continued, could result in a withdrawal or partial withdrawal from any such plan; and neither the Company nor any
other member of the Controlled Group has received any notice that any Multiemployer Pension Plan is in reorganization, that increased contributions may be required to avoid a reduction in plan benefits or the imposition of any excise tax, that any
such plan is or has been funded at a rate less than that required under Section 412 of the Code, that any such plan is or may be terminated, or that any such plan is or may become insolvent.

been filed by it and has paid all taxes and governmental charges due and payable with respect to such return, except any such taxes or charges which are being diligently contested in good faith by appropriate proceedings and for which adequate
reserves in accordance with GAAP shall have been set aside on its books. The MPW Companies have made adequate reserves on their books and records in accordance with GAAP for all taxes that have accrued but which are not yet due and payable. No MPW
Company has participated in any transaction that relates to a year of the taxpayer (which is still open under the applicable statute of limitations) which is a reportable transaction within the meaning of Treasury Regulation
Section 1.6011-4(b)(2) (irrespective of the date when the transaction was entered into).

9.14 Solvency, etc. The execution,
delivery and performance by each Borrower of each Loan Document to which it is a party, and the borrowings by the Borrowers hereunder, are not undertaken (a) with the actual intent to hinder, delay or defraud any creditor of such Borrower,
(b) in contemplation of insolvency, or (c) with a design to prefer any creditor of such Borrower. Each Borrower acknowledges that it has received reasonably equivalent value and fair consideration in exchange for the Obligations. On the
Closing Date, and immediately prior to and after giving effect to the issuance of each Letter of Credit and each borrowing hereunder and the use of the proceeds thereof, with respect to the MPW Companies on a consolidated basis, (a) the fair
value of their assets is greater than the amount of their liabilities (including disputed, contingent and unliquidated liabilities) as such value is established and liabilities evaluated in accordance with GAAP, (b) the present fair saleable
value of their assets is not less than the amount that will be required to pay the probable liability on their debts as those debts become absolute and matured, (c) they will able to realize upon their assets and pay their debts and other
liabilities (including disputed, contingent and unliquidated liabilities) as those debts mature in the normal course of business, (d) they do not intend to, and do not believe that they will, incur debts or liabilities beyond their ability to

and continues to maintain in good standing, all licenses, permits, authorizations, registrations and other approvals required under any Environmental Law and required for their respective ordinary course operations, and for their reasonably
anticipated future operations, and each MPW Company is in compliance with all terms and conditions thereof, except where the failure to do so could not reasonably be expected to result in material liability to any MPW Company and could not
reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect. No MPW Company or any of its properties or operations is subject to, or reasonably anticipates the issuance of, any written order from or
agreement with any Federal, state or local governmental authority, nor subject to any existing or threatened judicial or docketed administrative or other suit, action, complaint, judgment or proceeding, respecting any Environmental Law,
Environmental Claim or Hazardous Substance. There has been no leak, spill, discharge or other release of Hazardous Substances in, on, under or from the MPW Companys real property, or other conditions or circumstances

during the period or periods covered by any such projections and forecasts may differ from projected or forecasted results).

9.19
Intellectual Property. Each MPW Company owns and possesses or has a license or other right to use all patents, patent rights, trademarks, trademark rights, trade names, trade name rights, service marks, service mark rights and copyrights as

to pay any such tax or charge so long as it shall contest the validity thereof in good faith by appropriate proceedings
and shall set aside on its books adequate reserves with respect thereto in accordance with GAAP and, in the case of a claim which could become a Lien on any collateral, such contest proceedings shall stay the foreclosure of such Lien or the sale of
any portion of the collateral to satisfy such claim.

expected to entitle the PBGC to terminate, impose liability in respect of, or cause a trustee to be appointed to administer, any Pension Plan, unless the actions or events described in clauses (i), (ii) and (iii) individually or in the
aggregate would not have a Material Adverse Effect.

interview their employees and officers, cause an environmental site assessment to be performed if reasonably warranted by said Event of Default or Environmental Claim, and conduct such other activities as the Administrative Agent, in its good faith
discretion, deems appropriate to ensure the Borrowers compliance with the terms, covenants and conditions of this Agreement. The Borrowers shall, upon demand, pay all costs connected with such audit, which, until paid, shall become additional
indebtedness secured by the Loan Documents and shall bear interest at the rate applicable at the time of Event of Default as set forth in 4.1(b) of this Agreement. Nothing in this Agreement shall give or be construed as giving the Administrative
Agent the right to direct or control the MPW Companies actions in complying with Environmental Laws.

supervision of a consulting engineer. All reasonable costs and expenses of such Remedial Work and the Administrative Agents monitoring or review of such Remedial Work (including reasonable attorneys fees) shall be paid by the MPW
Companies. If the MPW Companies do not timely commence and diligently prosecute to completion the Remedial Work, the Administrative Agent may (but shall not be obligated to) cause such Remedial Work to be performed. The Borrowers agree to bear and
shall pay or reimburse the Administrative Agent on demand for all advances and reasonable expenses (including reasonable attorneys fees) relating to or incurred by the Administrative Agent in connection with monitoring, reviewing or performing
any Remedial Work.

(iii) Except with the Administrative Agents prior written consent, which consent shall not be unreasonably
withheld or delayed, the MPW Companies and their Subsidiaries shall not commence any Remedial Work or enter into any settlement agreement, consent decree or other compromise relating to any Hazardous Substances or Environmental Laws which would
reasonably be expected to, in the Administrative Agents reasonable judgment, impair the value of Administrative Agents security hereunder or under the Loan Documents. The Administrative Agents prior consent shall not be required,
however, if in the applicable MPW Companys reasonable judgment the presence of Hazardous Substances on, under or about the real property of the applicable MPW Company poses an immediate threat to the health, safety or welfare of any person or
is of such a nature that an immediate remedial response is necessary or required by applicable law. In such event the Borrowers shall notify the Administrative Agent as soon as practicable of all action taken.

Administrative Agent to take such action on its behalf under the provisions of this Agreement and each other Loan Document and to exercise such powers and perform such duties as are expressly delegated to it by the terms of this Agreement or any
other Loan Document, together with such powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary contained elsewhere in this Agreement or in any other Loan Document, the Administrative Agent shall not have any duty

69



---

any other Loan Document or otherwise exist against the Administrative Agent. Without limiting the generality of the
foregoing sentence, the use of the term agent herein and in other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine
of any applicable law. Instead, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting parties.

14.2 Issuing Lender. The Issuing Lender shall act on behalf of the Lenders (according to their Pro Rata Shares) with respect to any Letters of
Credit issued by it and the documents associated therewith. The Issuing Lender shall have all of the benefits and immunities (a) provided to the Administrative Agent in this Section 14 with respect to any acts taken or omissions
suffered by the Issuing Lender in connection with Letters of Credit issued by it or proposed to be issued by it and the applications and agreements for letters of credit pertaining to such Letters of Credit as fully as if the term
Administrative Agent, as used in this Section 14, included the Issuing Lender with respect to such acts or omissions and (b) as additionally provided in this Agreement with respect to the Issuing Lender.

14.3 Delegation of Duties. The Administrative Agent may execute any of its duties under this Agreement or any other Loan Document by or through
agents, employees or attorneys-in-fact and shall be entitled to advice of counsel and other consultants or experts concerning all matters pertaining to such duties. The Administrative Agent shall not be responsible for the negligence or misconduct
of any agent or attorney-in-fact that it selects in the absence of gross negligence or willful misconduct.

14.4 Exculpation of
Administrative Agent. None of the Administrative Agent nor any of its directors, officers, employees or agents shall (a) be liable for any action taken or omitted to be taken by any of them under or in connection with this Agreement or any
other Loan Document or the transactions contemplated hereby (except to the extent resulting from its own gross negligence or willful misconduct in connection with its duties expressly set forth herein as determined by a final, nonappealable judgment
by a court of competent jurisdiction), or (b) be responsible in any manner to any Lender or participant for any recital, statement, representation or warranty made by any MPW Company or Affiliate thereof, or any officer thereof, contained in
this Agreement or in any other Loan Document, or in any certificate, report, statement or other document referred to or provided for in, or received by the Administrative Agent under or in connection with, this Agreement or any other Loan Document,
or the validity, effectiveness, genuineness, enforceability or sufficiency of this Agreement or any other Loan Document (or the creation, perfection or priority of any Lien or security interest therein), or for any failure of any Borrower or any
other party to any Loan Document to perform its Obligations hereunder or thereunder. The Administrative Agent shall not be under any obligation to any Lender to ascertain or to inquire as to the observance or performance of any of the agreements
contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of the Borrowers, their Subsidiaries or their Affiliates.

writing, communication, signature, resolution, representation, notice, consent, certificate, electronic mail message, affidavit, letter, telegram, facsimile, telex or telephone message, statement or other document or conversation

---

believed by it to be genuine and correct and to have been signed, sent or made by the proper Person or Persons, and upon
advice and statements of legal counsel (including counsel to the Borrowers), independent accountants and other experts selected by the Administrative Agent. The Administrative Agent shall be fully justified in failing or refusing to take any action
under this Agreement or any other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders as it deems appropriate and, if it so requests, confirmation from the Lenders of their obligation to indemnify the
Administrative Agent against any and all liability and expense which may be incurred by it by reason of taking or continuing to take any such action. The Administrative Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement or any other Loan Document in accordance with a request or consent of the Required Lenders and such request and any action taken or failure to act pursuant thereto shall be binding upon each Lender. For purposes of
determining compliance with the conditions specified in Section 12, each Lender that has signed this Agreement shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required
thereunder to be consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed Closing Date specifying its objection thereto.

14.6 Notice of Default. The Administrative Agent shall not be deemed to have knowledge or notice of the occurrence of any Event of
Default or Unmatured Event of Default except with respect to defaults in the payment of principal, interest and fees required to be paid to the Administrative Agent for the account of the Lenders, unless the Administrative Agent shall have received
written notice from a Lender or the Borrowers referring to this Agreement, describing such Event of Default or Unmatured Event of Default and stating that such notice is a notice of default. The Administrative Agent will notify the
Lenders of its receipt of any such notice. The Administrative Agent shall take such action with respect to such Event of Default or Unmatured Event of Default as may be requested by the Required Lenders in accordance with Section 13;
provided that unless and until the Administrative Agent has received any such request, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Event of Default or
Unmatured Event of Default as it shall deem advisable or in the best interest of the Lenders.

14.7 Credit Decision. Each Lender
acknowledges that the Administrative Agent has not made any representation or warranty to it, and that no act by the Administrative Agent hereafter taken, including any consent and acceptance of any assignment or review of the affairs of the MPW
Companies, shall be deemed to constitute any representation or warranty by the Administrative Agent to any Lender as to any matter, including whether the Administrative Agent has disclosed material information in its possession. Each Lender
represents to the Administrative Agent that it has, independently and without reliance upon the Administrative Agent and based on such documents and information as it has deemed appropriate, made its own appraisal of and investigation into the
business, prospects, operations, property, financial and other condition and creditworthiness of the MPW Companies, and made its own decision to enter into this Agreement and to extend credit to the Borrowers hereunder. Each Lender also represents
that it will, independently and without reliance upon the Administrative Agent and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not
taking action under this Agreement and the other Loan Documents, and to make such investigations as it deems



71



---

necessary to inform itself as to the business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrowers. Except for notices, reports and other documents expressly herein required to be furnished to the Lenders by the Administrative Agent, the Administrative Agent shall not have any duty or responsibility to provide
any Lender with any credit or other information concerning the business, prospects, operations, property, financial or other condition or creditworthiness of the Borrowers which may come into the possession of the Administrative Agent.

14.8 Indemnification. Whether or not the transactions contemplated hereby are consummated, each Lender shall indemnify upon demand the
Administrative Agent and its directors, officers, employees and agents (to the extent not reimbursed by or on behalf of the Borrowers and without limiting the obligation of the Borrowers to do so), according to its applicable Pro Rata Share, from
and against any and all Indemnified Liabilities (as hereinafter defined); provided that no Lender shall be liable for any payment to any such Person of any portion of the Indemnified Liabilities to the extent determined by a final,
nonappealable judgment by a court of competent jurisdiction to have resulted from the applicable Persons own gross negligence or willful misconduct. No action taken in accordance with the directions of the Required Lenders shall be deemed to
constitute gross negligence or willful misconduct for purposes of this Section. Without limitation of the foregoing, each Lender shall reimburse the Administrative Agent upon demand for its ratable share of any costs or out-of-pocket expenses
(including Attorney Costs and Taxes) incurred by the Administrative Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise)
of, or legal advice in respect of rights or responsibilities under, this Agreement, any other Loan Document, or any document contemplated by or referred to herein, to the extent that the Administrative Agent is not reimbursed for such expenses by or
on behalf of the Borrowers. The undertaking in this Section shall survive repayment of the Loans, cancellation of the Notes, expiration or termination of the Letters of Credit, any foreclosure under, or modification, release or discharge of, any or
all of the Collateral Documents, termination of this Agreement and the resignation or replacement of the Administrative Agent.

14.9
Administrative Agent in Individual Capacity. LaSalle and its Affiliates may make loans to, issue letters of credit for the account of, accept deposits from, acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with the MPW Companies and Affiliates as though LaSalle were not the Administrative Agent hereunder and without notice to or consent of any Lender. Each Lender acknowledges that, pursuant to such
activities, LaSalle or its Affiliates may receive information regarding the MPW Companies or their Affiliates (including information that may be subject to confidentiality obligations in favor of the MPW Companies or such Affiliates) and acknowledge
that the Administrative Agent shall be under no obligation to provide such information to them. With respect to their Loans (if any), LaSalle and its Affiliates shall have the same rights and powers under this Agreement as any other Lender and may
exercise the same as though LaSalle were not the Administrative Agent, and the terms Lender and Lenders include LaSalle and its Affiliates, to the extent applicable, in their individual capacities.

14.10 Successor Administrative Agent. The Administrative Agent may resign as Administrative Agent upon 30 days notice to the Lenders. If the
Administrative Agent resigns



72



---

under this Agreement, the Required Lenders shall, with (so long as no Event of Default exists) the consent of the
Borrowers (which shall not be unreasonably withheld or delayed), appoint from among the Lenders a successor agent for the Lenders. If no successor agent is appointed prior to the effective date of the resignation of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Lenders and the Borrowers, a successor agent from among the Lenders. Upon the acceptance of its appointment as successor agent hereunder, such successor agent shall succeed to all the
rights, powers and duties of the retiring Administrative Agent and the term Administrative Agent shall mean such successor agent, and the retiring Administrative Agents appointment, powers and duties as Administrative Agent shall
be terminated. After any retiring Administrative Agents resignation hereunder as Administrative Agent, the provisions of this Section 14 and Sections 15.5 and 15.16 shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent under this Agreement. If no successor agent has accepted appointment as Administrative Agent by the date which is 30 days following a retiring Administrative Agents notice of
resignation, the retiring Administrative Agents resignation shall nevertheless thereupon become effective and the Lenders shall perform all of the duties of the Administrative Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above.

14.11 Collateral Matters. The Lenders irrevocably authorize the Administrative
Agent, at its option and in its discretion, (a) to release any Lien granted to or held by the Administrative Agent under any Collateral Document (i) upon termination of the Commitments and payment in full of all Loans and all other
obligations of the Borrowers hereunder and the expiration or termination of all Letters of Credit; (ii) constituting property sold or to be sold or disposed of as part of or in connection with any disposition permitted hereunder; or
(iii) subject to Section 15.1, if approved, authorized or ratified in writing by the Required Lenders; or (b) to subordinate its interest in any Collateral to any holder of a Lien on such Collateral which is permitted by
Section 11.2(d)(i) or (d)(iii) (it being understood that the Administrative Agent may conclusively rely on a certificate from the Borrowers in determining whether the Debt secured by any such Lien is permitted by
Section 11.1(b)). Upon request by the Administrative Agent at any time, the Lenders will confirm in writing the Administrative Agents authority to release, or subordinate its interest in, particular types or items of Collateral
pursuant to this Section 14.11. Each Lender hereby authorizes the Administrative Agent to give blockage notices in connection with any Subordinated Debt at the direction of Required Lenders and agrees that it will not act unilaterally to
deliver such notices.

14.12 Administrative Agent May File Proofs of Claim. In case of the pendency of any receivership, insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to any MPW Company, the Administrative Agent (irrespective of whether the principal of any Loan shall then be due and payable as
herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrowers) shall be entitled and empowered, by intervention in such proceeding or otherwise:

(a) to file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Loans, and all other Obligations that
are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the reasonable compensation,

expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel
and all other amounts due the Lenders and the Administrative Agent under Sections 5, 15.5 and 15.17) allowed in such judicial proceedings; and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that
the Administrative Agent shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and
its agents and counsel, and any other amounts due the Administrative Agent under Sections 5, 15.5 and 15.17.

Nothing contained
herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any
Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding.

14.13 Other
Agents; Arrangers and Managers. None of the Lenders or other Persons identified on the facing page or signature pages of this Agreement as a syndication agent, documentation agent, co-agent, book
manager, lead manager, arranger, lead arranger or co-arranger, if any, shall have any right, power, obligation, liability, responsibility or duty under this Agreement other than, in the case of
such Lenders, those applicable to all Lenders as such. Without limiting the foregoing, none of the Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it
has not relied, and will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder.

SECTION 15 GENERAL.

15.1 Waiver;
Amendments. No delay on the part of the Administrative Agent or any Lender in the exercise of any right, power or remedy shall operate as a waiver thereof, nor shall any single or partial exercise by any of them of any right, power or remedy
preclude other or further exercise thereof, or the exercise of any other right, power or remedy. No amendment, modification or waiver of, or consent with respect to, any provision of this Agreement or the other Loan Documents shall in any event be
effective unless the same shall be in writing and acknowledged by Lenders having an aggregate Pro Rata Shares of not less than the aggregate Pro Rata Shares expressly designated herein with respect thereto or, in the absence of such designation as
to any provision of this Agreement, by the Required Lenders, and then any such amendment, modification, waiver or consent shall be effective only in the specific instance and for the specific purpose for which given. No amendment, modification,
waiver or consent shall (a) extend or increase the Commitment of any Lender without the written consent of such Lender, (b) extend the date scheduled for payment of any principal (excluding mandatory



74



---

prepayments) of or interest on the Loans or any fees payable hereunder without the written consent of each Lender
directly affected thereby, (c) reduce the principal amount of any Loan, the rate of interest thereon or any fees payable hereunder, without the consent of each Lender directly affected thereby (except for periodic adjustments of interest rates
and fees resulting from a change in the Applicable Margin as provided for in this Agreement); or (d) release any party from its obligations under the Guaranty or all or any substantial part of the Collateral granted under the Collateral
Documents, change the definition of Required Lenders, any provision of this Section 15.1 or reduce the aggregate Pro Rata Share required to effect an amendment, modification, waiver or consent, without, in each case, the written consent
of all Lenders. No provision of Sections 6.2.2 or 6.3 with respect to the timing or application of mandatory prepayments of the Loans shall be amended, modified or waived without the consent of the Required Lenders. No provision of
Section 14 or other provision of this Agreement affecting the Administrative Agent in its capacity as such shall be amended, modified or waived without the consent of the Administrative Agent. No provision of this Agreement relating to
the rights or duties of the Issuing Lender in its capacity as such shall be amended, modified or waived without the consent of the Issuing Lender. No provision of this Agreement relating to the rights or duties of the Swing Line Lender in its
capacity as such shall be amended, modified or waived without the consent of the Swing Line Lender.

15.2 Confirmations. The
Borrowers and each holder of a Note agree from time to time, upon written request received by it from the other, to confirm to the other in writing (with a copy of each such confirmation to the Administrative Agent) the aggregate unpaid principal
amount of the Loans then outstanding under such Note.

15.3 Notices. Except as otherwise provided in Sections 2.2.2 and
2.2.3, all notices hereunder shall be in writing (including facsimile transmission) and shall be sent to the applicable party at its address shown on Annex B or at such other address as such party may, by written notice received by the
other parties, have designated as its address for such purpose. Notices sent by facsimile transmission shall be deemed to have been given when sent; notices sent by mail shall be deemed to have been given three Business Days after the date when sent
by registered or certified mail, postage prepaid; and notices sent by hand delivery or overnight courier service shall be deemed to have been given when received. For purposes of Sections 2.2.2 and 2.2.3, the Administrative Agent shall
be entitled to rely on telephonic instructions from any person that the Administrative Agent in good faith believes is an authorized officer or employee of the Borrowers, and the Borrowers shall hold the Administrative Agent and each other Lender
harmless from any loss, cost or expense resulting from any such reliance.

15.4 Computations. Where the character or amount
of any asset or liability or item of income or expense is required to be determined, or any consolidation or other accounting computation is required to be made, for the purpose of this Agreement, such determination or calculation shall, to the
extent applicable and except as otherwise specified in this Agreement, be made in accordance with GAAP, consistently applied; provided that if the Borrowers notify the Administrative Agent that the Borrowers wish to amend any covenant in
Sections 10 or 11.14 (or any related definition) to eliminate or to take into account the effect of any change in GAAP on the operation of such covenant (or if the Administrative Agent notifies the Borrowers that the Required Lenders wish to
amend Sections 10 or 11.14 (or any related definition) for such purpose), then the Borrowers compliance with such covenant shall be determined on the basis of



75



---

GAAP in effect immediately before the relevant change in GAAP became effective, until either such notice is withdrawn or
such covenant (or related definition) is amended in a manner satisfactory to the Borrowers and the Required Lenders.

15.5 Costs,
Expenses and Taxes. The Borrowers jointly and severally agree to pay on demand all reasonable out-of-pocket costs and expenses of the Administrative Agent (including Attorney Costs and any Taxes) in connection with the preparation, execution,
syndication, delivery and administration (including perfection and protection of any Collateral and the costs of Intralinks (or other similar service), if applicable) of this Agreement, the other Loan Documents and all other documents provided for
herein or delivered or to be delivered hereunder or in connection herewith (including any amendment, supplement or waiver to any Loan Document), whether or not the transactions contemplated hereby or thereby shall be consummated, and all reasonable
out-of-pocket costs and expenses (including Attorney Costs and any Taxes) incurred by the Administrative Agent and each Lender after an Event of Default in connection with the collection of the Obligations or the enforcement of this Agreement the
other Loan Documents or any such other documents or during any workout, restructuring or negotiations in respect thereof. In addition, the Borrowers jointly and severally agree to pay, and to save the Administrative Agent and the Lenders harmless
from all liability for, any fees of the Borrowers auditors in connection with any reasonable exercise by the Administrative Agent and the Lenders of their rights pursuant to Section 10.2. All Obligations provided for in this
Section 15.5 shall survive repayment of the Loans, cancellation of the Notes, expiration or termination of the Letters of Credit and termination of this Agreement.

15.6 Assignments; Participations.

15.6.1 Assignments. (a) Any Lender may at any time assign to one or more Persons (any such Person, an Assignee) all or any portion of such Lenders Loans and Commitments, with the prior written consent of
the Administrative Agent, the Issuing Lender (for an assignment of the Revolving Loans and the Revolving Commitment) and, so long as no Event of Default exists, the Borrowers (which consents shall not be unreasonably withheld or delayed and shall
not be required for an assignment by a Lender to a Lender or an Affiliate of a Lender). Except as the Administrative Agent may otherwise agree, any such assignment shall be in a minimum aggregate amount equal to $5,000,000 or, if less, the remaining
Commitment and Loans held by the assigning Lender. The Borrowers and the Administrative Agent shall be entitled to continue to deal solely and directly with such Lender in connection with the interests so assigned to an Assignee until the
Administrative Agent shall have received and accepted an effective assignment agreement in substantially the form of Exhibit D hereto (an Assignment Agreement) executed, delivered and fully completed by the applicable
parties thereto and a processing fee of $3,500 from the assigning Lender or the Assignee. No assignment may be made to any Person if at the time of such assignment the Borrowers would be obligated to pay any greater amount under Sections 7.6
or 8 to the Assignee than the Borrowers are then obligated to pay to the assigning Lender under such Sections (and if any assignment is made in violation of the foregoing, the Borrowers will not be required to pay such greater amounts). Any
attempted assignment not made in accordance with this Section



76



---

15.6.1 shall be treated as the sale of participation under Section 15.6.2. The
Borrowers shall be deemed to have granted their consent to any assignment requiring their consent hereunder unless the Borrowers have expressly objected to such assignment within three Business Days after notice thereof.

(b) From and after the date on which the conditions described above have been met, (i) such Assignee shall be deemed automatically to have become a
party hereto and, to the extent that rights and obligations hereunder have been assigned to such Assignee pursuant to such Assignment Agreement, shall have the rights and obligations of a Lender hereunder and (ii) the assigning Lender, to the
extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment Agreement, shall be released from its rights (other than its indemnification rights) and obligations hereunder. Upon the request of the Assignee (and,
as applicable, the assigning Lender) pursuant to an effective Assignment Agreement, each Borrower shall execute and deliver to the Administrative Agent for delivery to the Assignee (and, as applicable, the assigning Lender) a Note in the principal
amount of the Assignees Pro Rata Share of the Revolving Commitment plus the principal amount of the Assignees Term Loans (and, as applicable, a Note in the principal amount of the Pro Rata Share of the Revolving Commitment retained by
the assigning Lender plus the principal amount of the Term Loans retained by the assigning Lender). Each such Note shall be dated the effective date of such assignment. Upon receipt by the assigning Lender of such Note, the assigning Lender shall
return to the Borrowers any prior Note held by it.

(c) Any Lender may at any time pledge or assign a security interest in all or any
portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security
interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

15.6.2 Participations. Any Lender may at any time sell to one or more Persons participating interests in its Loans, Commitments or other interests
hereunder (any such Person, a Participant). In the event of a sale by a Lender of a participating interest to a Participant, (a) such Lenders obligations hereunder shall remain unchanged for all purposes, (b) the
Borrowers and the Administrative Agent shall continue to deal solely and directly with such Lender in connection with such Lenders rights and obligations hereunder and (c) all amounts payable by the Borrowers shall be determined as if
such Lender had not sold such participation and shall be paid directly to such Lender. No Participant shall have any direct or indirect voting rights hereunder except with respect to any event described in Section 15.1 expressly
requiring the unanimous vote of all Lenders or, as applicable, all affected Lenders. Each Lender agrees to incorporate the requirements of the preceding sentence into each participation agreement which such Lender enters into with any Participant.
The Borrowers agree that if amounts outstanding under this Agreement are due and payable (as a result of acceleration or otherwise), each Participant shall be deemed to have the right of set-off in respect of its participating interest in amounts
owing under this Agreement and with respect to any Letter of Credit to the same extent as if the



77



---

amount of its participating interest were owing directly to it as a Lender under this Agreement;
provided that such right of set-off shall be subject to the obligation of each Participant to share with the Lenders, and the Lenders agree to share with each Participant, as provided in Section 7.5. The Borrowers also agree that
each Participant shall be entitled to the benefits of Section 7.6 or 8 as if it were a Lender (provided that on the date of the participation no Participant shall be entitled to any greater compensation pursuant to
Section 7.6 or 8 than would have been paid to the participating Lender on such date if no participation had been sold and that each Participant complies with Section 7.6(d) as if it were an Assignee).

15.7 Register. The Administrative Agent shall maintain a copy of each Assignment Agreement delivered and accepted by it and register (the
Register) for the recordation of names and addresses of the Lenders and the Commitment of each Lender from time to time and whether such Lender is the original Lender or the Assignee. No assignment shall be effective unless and
until the Assignment Agreement is accepted and registered in the Register. All records of transfer of a Lenders interest in the Register shall be conclusive, absent manifest error, as to the ownership of the interests in the Loans. The
Administrative Agent shall not incur any liability of any kind with respect to any Lender with respect to the maintenance of the Register.

15.8 GOVERNING LAW. THIS AGREEMENT AND EACH NOTE SHALL BE A CONTRACT MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF THE STATE OF OHIO APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE,
WITHOUT REGARD TO CONFLICT OF LAWS PRINCIPLES.

15.9 Confidentiality. As required by federal law and the Administrative
Agents policies and practices, the Administrative Agent may need to obtain, verify, and record certain customer identification information and documentation in connection with opening or maintaining accounts, or establishing or continuing to
provide services. The Administrative Agent and each Lender agree to use commercially reasonable efforts (equivalent to the efforts the Administrative Agent or such Lender applies to maintain the confidentiality of its own confidential information)
to maintain as confidential all information provided to them by any MPW Company and designated as confidential, except that the Administrative Agent and each Lender may disclose such information (a) to Persons employed or engaged by the
Administrative Agent or such Lender in evaluating, approving, structuring or administering the Loans and the Commitments; (b) to any assignee or participant or potential assignee or participant that has agreed to comply with the covenant
contained in this Section 15.9 (and any such assignee or participant or potential assignee or participant may disclose such information to Persons employed or engaged by them as described in clause (a) above); (c) as required
or requested by any federal or state regulatory authority or examiner, or any insurance industry association, or as reasonably believed by the Administrative Agent or such Lender to be compelled by any court decree, subpoena or legal or
administrative order or process; (d) as, on the advice of the Administrative Agents or such Lenders counsel, is required by law; (e) in connection with the exercise of any right or remedy under the Loan Documents or in
connection with any litigation to which the Administrative Agent or such Lender is a party; (f) to any nationally recognized rating



78



---

agency that requires access to information about a Lenders investment portfolio in connection with ratings issued
with respect to such Lender; (g) to any Affiliate of the Administrative Agent, the Issuing Lender or any other Lender who may provide Bank Products to the MPW Companies; or (h) that ceases to be confidential through no fault of the
Administrative Agent or any Lender. Notwithstanding the foregoing, the Borrowers consent to the publication by the Administrative Agent or any Lender of a tombstone or similar advertising material relating to the financing transactions contemplated
by this Agreement, and the Administrative Agent reserves the right to provide to industry trade organizations information necessary and customary for inclusion in league table measurements.

15.10 Severability. Whenever possible each provision of this Agreement shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Agreement. All obligations of the Borrowers and rights of the Administrative Agent and the Lenders expressed herein or in any other Loan Document shall be in addition to and not in limitation of those provided by
applicable law.

15.11 Nature of Remedies. All Obligations of the Borrowers and rights of the Administrative Agent and the Lenders
expressed herein or in any other Loan Document shall be in addition to and not in limitation of those provided by applicable law. No failure to exercise and no delay in exercising, on the part of the Administrative Agent or any Lender, any right,
remedy, power or privilege hereunder, shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right,
remedy, power or privilege.

15.12 Entire Agreement. This Agreement, together with the other Loan Documents, embodies the entire
agreement and understanding among the parties hereto and supersedes all prior or contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof (except as relates to the fees
described in Section 5.3) and any prior arrangements made with respect to the payment by the Borrowers of (or any indemnification for) any fees, costs or expenses payable to or incurred (or to be incurred) by or on behalf of the
Administrative Agent or the Lenders.

15.13 Counterparts. This Agreement may be executed in any number of counterparts and by
the different parties hereto on separate counterparts and each such counterpart shall be deemed to be an original, but all such counterparts shall together constitute but one and the same Agreement. Receipt of an executed signature page to this
Agreement by facsimile or other electronic transmission shall constitute effective delivery thereof. Electronic records of executed Loan Documents maintained by the Lenders shall deemed to be originals.

15.14 Successors and Assigns. This Agreement shall be binding upon the Borrowers, the Lenders and the Administrative Agent and their
respective successors and assigns, and shall inure to the benefit of the Borrowers, the Lenders and the Administrative Agent and the successors and assigns of the Lenders and the Administrative Agent. No other Person shall be a direct or indirect
legal beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement or any of the other Loan Documents. The Borrowers may not assign or transfer any of their rights or Obligations under this Agreement
without the prior written consent of the Administrative Agent and each Lender.
