benefit of Mortgagor, the Company, the other Guarantors or the Property, including, without limitation: (a) principal, interest, late charges, fees and other amounts due under the Credit Agreement, the Other Documents or this Mortgage;

Ohio 
  

 - 4 - 

 a judgment of foreclosure), Mortgagor fails to perform or observe any covenant or obligation under this
Mortgage including, without limitation, payment of any of the foregoing, Mortgagee may (but shall not be obligated to) take such steps as are reasonably necessary to remedy any such nonperformance or nonobservance and provide payment thereof. All
amounts advanced by Mortgagee shall be added to the amount secured by this Mortgage (and, if advanced after the entry of a judgment of foreclosure, by such judgment of foreclosure), and shall be due and payable on demand, together with interest at
the rate borne by the Tranche A Loans or the Tranche C Loans, as applicable, such interest to be calculated from the date of such advance to the date of repayment thereof. Mortgagee is authorized and empowered to do all things permitted to be done
as a mortgagee under the mechanic’s lien laws of the State of Ohio (including section 1311.14 of the Ohio Revised Code), and all acts amendatory or supplementary thereto.”; 
 (g) Section 8.3 is hereby amended and restated in full by deleting it in its entirety and replacing it with the following: 
 “Foreclosure. Mortgagee may institute any one or more actions of mortgage foreclosure against all or any part of the Property, or take
such other action at law, equity or by contract for the enforcement of this Mortgage and realization on the security herein or elsewhere provided for, as the law may allow, and may proceed therein to final judgment and execution for the entire
unpaid balance of the Liabilities. The unpaid balance of any judgment shall bear interest at the greater of (a) the statutory rate provided for judgments, or (b) the rate borne by the Tranche A Loans or the Tranche C Loans, as applicable.
Without limiting the foregoing, Mortgagee may foreclose this Mortgage and exercise its rights as a secured party for all or any portion of the Liabilities which are then due and payable, subject to the continuing lien of this Mortgage for the
balance not then due and payable. In case of any sale of the Property by judicial proceedings, the Property may be sold in one parcel or in such parcels, manner or order as Mortgagee in its sole discretion may elect. Mortgagor, for itself and anyone
claiming by, through or under it, hereby agrees that Mortgagee shall in no manner, in law or in equity, be limited, except as herein provided, in the exercise of its rights in the Property or in any other security hereunder or otherwise appertaining
to the Liabilities or any other obligation secured by this Mortgage, whether by any statute, rule or precedent which may otherwise require said security to be marshalled in any manner and Mortgagor, for itself and others as aforesaid, hereby
expressly waives and releases any right to or benefit thereof. The failure to make any tenant a defendant to a foreclosure proceeding shall not be asserted by Mortgagor as a defense in any proceeding instituted by Mortgagee to collect the
Liabilities or any deficiency remaining unpaid after the foreclosure sale of the Property.”; 
 Mt. Sterling, Ohio 
  

 - 5 - 

 it being the intent of this Amendment that the obligations of the Mortgagor under the Credit Agreement shall be entitled
to the benefits and collateral security under the Existing Mortgage as fully as if such obligations had been incurred under the Original Credit Agreement as originally in effect. 
 Section 3. Confirmation and Restatement. The Mortgagor, in order to continue to secure the payment of the Liabilities, hereby confirms and
restates (a) the grant of a mortgage pursuant to the Existing Mortgage to the Mortgagee with respect to the Property and (b) the grant pursuant to the Existing Mortgage of a security interest in the Service Equipment. Nothing contained in
this Amendment shall be construed as (a) a novation of the Liabilities or (b) a release or waiver of all or any portion of the grant of a mortgage to the Mortgagee with respect to the Property or the grant to the Mortgagee of a security
interest in the Service Equipment pursuant to the Existing Mortgage. 
 Section 4. Representations and Warranties. The Mortgagor
hereby represents and warrants that the representations and warranties made by it in the Existing Mortgage are true and complete in all material respects on and as of the date hereof as if made on and as of the date hereof. 
 Section 5. Covenants. The Mortgagor hereby covenants and agrees to perform each and every duty and obligation of the Mortgagor contained in
the Existing Mortgage as amended by this Amendment. 
 Section 6. Effectiveness. This Amendment shall be effective as of the day
and year first written above upon its execution and delivery by the Mortgagor. Except as herein provided, the Existing Mortgage shall remain unchanged and in full force and effect.

which shall constitute one instrument.

 (h) Section 8.3 is hereby amended and restated in full by deleting it in its
entirety and replacing it with the following: 
 “Foreclosure. Beneficiary may institute any one or more actions of
foreclosure against all or any part of the Property, or take such other action at law, equity or by contract for the enforcement of this Deed of Trust and realization on the security herein or elsewhere provided for, as the law may allow, and may
proceed therein to final judgment and execution for the entire unpaid balance of the Liabilities. The unpaid balance of any judgment shall bear interest at the greater of (a) the statutory rate provided for judgments, or (b) the rate borne
by the Tranche A Loans or the Tranche C Loans, as the case may be. Without limiting the foregoing, Beneficiary may cause the foreclosure of this Deed of Trust and exercise its rights as a secured party for all or any portion of the Liabilities which
are then due and payable, subject to the continuing lien of this Deed of Trust for the balance not then due and payable. In case of any sale of the Property by judicial proceedings, the Property may be sold in one parcel or in such parcels, manner
or order as Beneficiary in its sole discretion may elect. Grantor, for itself and anyone claiming by, through or under it, hereby agrees that Beneficiary shall in no manner, in law or in equity, be limited, except as herein provided, in the exercise
of its rights in the Property or in any other security hereunder or otherwise appertaining to the Liabilities or any other obligation secured by this Deed of Trust, whether by any statute, rule or precedent which may otherwise require said security
to be marshalled in any manner and Grantor, for itself and others as aforesaid, hereby expressly waives and releases any right to or benefit thereof. The failure to make any tenant a defendant to a foreclosure proceeding shall not be asserted by
Grantor as a defense in any proceeding instituted by Beneficiary to collect the Liabilities or any deficiency remaining unpaid after the foreclosure sale of the Property.”; 
 (i) Section 10.2 is hereby amended and restated in full by deleting it in its entirety and replacing it with the following:

 “Further Remedies of Beneficiary. Beneficiary may proceed as if all of the Property were real property, or Beneficiary
may elect to treat any of the Property which consists of a right in action or which is property that can be severed from the Real Property and the improvements thereon without causing structural damage thereto as if the same were personal property
and dispose of the same in accordance with the terms hereof, separate and apart from the sale of real property, the remainder of the Property being treated as real property. Beneficiary may cause any such sale or other disposition to be conducted
immediately, or Beneficiary may delay any such sale or other disposition for such period of time as Beneficiary deems to be in its best interest. Should Beneficiary desire that more than one such sale or other disposition be conducted, Beneficiary
may, at its option, cause the same to be conducted simultaneously or successively on the same day, or at such different days or times and in such order as Beneficiary may deem to be in its best interest.

 Should Beneficiary request and direct the Trustee to sell the Property or any part thereof which is real
property or which Beneficiary has elected to treat as real property, upon such election, Trustee may proceed to foreclose this Deed of Trust in respect of said real property in the following manner. The Trustee at the request of the Beneficiary
shall proceed to take possession and to sell any of the Property (in one or more parcels), in whole or in parcels, at public venue, to the highest bidder, for cash, at a front door (to be designated by Trustee) of the building then appointed for
holding the foreclosure sale by, the Circuit Court of the County in which the Real Estate is located, first giving notice of such sale in the manner prescribed by statute; and upon such sale shall execute and deliver a deed of conveyance of the
property sold (subject to the Permitted Exceptions) to the purchaser or purchasers thereof. The Trustee shall receive the proceeds of said sale out of which the Trustee shall pay (A) the costs and expenses of executing this trust, including
lawful compensation to the Trustee for its services as provided by statute, and a reasonable attorney’s fee, which shall be immediately due upon first publication of sale as aforesaid; (B) to the Beneficiary, upon the usual vouchers
therefor, any of the Liabilities including money advanced for ground rents, maintenance, abstracts, title reports, judgments upon statutory lien claims and any other advances hereunder and interest thereon at the rate borne by the Tranche A Loans or
the Tranche C Loans, as the case may be; (C) the balance of such proceeds, if any, shall be paid as required by law. The purchaser at any foreclosure sale shall not be obligated to look at the application of the proceeds thereof. If the
Beneficiary should become the purchaser, it shall be entitled to credit any of the unpaid balance of the Liabilities against the amount of the purchase price. The Trustee covenants faithfully to perform the Trust herein created. Trustee may postpone
the sale of all or any portion of the Property by public announcement at such time and place of sale (or by any other means permitted by law) and from time to time thereafter may postpone such sale by public announcement (or by any other means
permitted by law). Beneficiary may foreclose or otherwise realize upon, and Trustee may sell, one parcel or any other part or parts of the Property, on one or more occasions, without releasing this Deed of Trust, or precluding the further
foreclosure or other realization hereunder of any other parcels or other parts of the Property not so foreclosed or realized upon. Beneficiary or any assignee hereof shall have the right to bid at and become purchaser at any foreclosure sale,
applying against the purchase price all or a part of any Liabilities then due and owing. Prior to electing to foreclose this Deed of Trust, Beneficiary may cause an environmental assessment of the Property to be made and in furtherance thereof, may
enter the Property by and through its agents and grant permission to independent contractors to enter the Property for assessment purposes. Any expenses incurred in so doing shall be deemed expenses described in clause (B) above.”;
