ARTICLE TWO 
 The Securities 

Section 2.01. Terms and Form. 
 The
Securities may be issued from time to time in one or more Series. Each Series shall be limited to such aggregate principal amount, shall bear the title and interest at the rates and from the dates, shall mature at the times, shall or may be
redeemable at the prices and upon the terms, and shall contain or be subject to all terms as shall be established in an indenture supplemental hereto or by or pursuant to a Board Vote (and, to the extent not set forth in the Board Vote, in an
Officers’ Certificate detailing the adoption of terms pursuant to the Board Vote). Securities of a Series shall be substantially identical except as to denomination and except as may be otherwise provided in a Board Vote and/or an
Officers’ Certificate or in an indenture supplemental hereto. In case of Securities of a Series to be issued from time to time, the Officers’ Certificate may provide for the method by which specified terms (such as interest rate, maturity
date, record date or date from which interest shall accrue) are to be determined. 
 The Securities of each Series hereunder shall be
substantially in the form set forth in Exhibit A or in such form, including with respect to whether such Series shall be issued in whole or in part in the form of one or more Global Securities and the Depository for such Global Security or
Securities, as shall be established pursuant to a Board Vote (and, to the extent not set forth in the Board Vote, in an Officers’ Certificate detailing the adoption of such form) or one or more indenture supplements to this Indenture, in each
case, with such insertions, omissions, substitutions, and other variations as are required or permitted by this Indenture, such Board Vote or such indenture supplement. If a form of any Security is approved by a Board Vote, such Officers’
Certificate shall also state that all conditions precedent relating to the authentication and delivery of such Security have been complied with and shall be accompanied by a copy of the Board Vote by or pursuant to which the form of such Security
has been approved. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall approve the form of the Securities and any notation, legend or endorsement on them, such approval to be
conclusively evidenced by the execution of such Securities. Unless the form of a Security of a Series provides otherwise, each Security shall be dated the date of its authentication. 

  
 4 

 Unless the form of a Security of a Series provides otherwise, the Securities of such Series shall
be issued in denominations of $1,000 or multiples thereof. 
 Section 2.02. Form of Legend for Global Security. 

Any Global Security issued hereunder shall bear a legend in substantially the following form: 

“This Security is a Global Security within the meaning of the Indenture hereinafter referred to and is registered in the name of the
Depository or a nominee of the Depository. This Security is exchangeable for Securities registered in the name of a person other than the Depository or its nominee only in the limited circumstances described in the Indenture, and may not be
transferred except as a whole by the Depository to a nominee of the Depository, by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any such nominee to a successor Depository or a nominee of
such successor Depository.” 
 Section 2.03. Execution and Authentication. 

Two Officers shall sign the Securities for the Company and may employ facsimile signatures. The Company’s seal shall be impressed, affixed
or reproduced on the Securities. 
 If an Officer whose signature is on a Security no longer holds that office at the time the Trustee
authenticates the Security, the Security shall be valid nevertheless. 
 The aggregate principal amount of Securities that may be
authenticated and delivered under this Indenture is unlimited. The Trustee shall authenticate Securities for original issue upon (or in accordance with such procedures acceptable to the Trustee set forth in) a written order of the Company signed by
two Officers or by an Officer and an Assistant Treasurer of the Company. 
 A Security shall not be valid until the Trustee manually signs
the certificate of authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. The Trustee’s authentication shall be in the following form (except that where
applicable any successor or additional Trustee’s name for Securities of a Series shall be substituted for the Trustee named below): 

This is one of the Securities of the Series designated therein issued under the within mentioned Indenture.

 Section 2.04. Registrar and Paying Agent. 

The Company shall designate a Registrar who shall maintain an office or agency where Securities may be presented for registration of transfer
and where Securities may be presented for exchange (the “Registrar”) and a paying agent who shall maintain an office or agency where Securities may be presented for payment (the “Paying Agent”). Initially, U.S. Bank
National Association, Corporate Trust Services, 100 Wall Street, Suite 1600, New York, New York 10005, will act as the Registrar and Paying Agent. The Registrar shall keep a register of the Securities and of their transfer and exchange. With the
consent of the Trustee, which shall not be unreasonably withheld, the Company may designate one or more co-registrars and one or more Paying Agents. The term “Registrar” includes any additional co-registrar. The term “Paying
Agent” includes any additional paying agent. The Company shall notify the Trustee of the name and address of any Agent not a party to this Indenture. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such.

 Section 2.05. Paying Agent to Hold Money in Trust. 

The Company, by written agreement, shall require each Paying Agent other than the Trustee to agree that the Paying Agent will hold in trust for
the benefit of Securityholders or the Trustee all money held by the Paying Agent for the payment of principal of and premium, if any, or interest on the Securities, and will notify the Trustee of any default by the Company in making any such
payment. If the Company acts as Paying Agent, it shall segregate the money and hold it as a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon doing so the Paying Agent shall have
no further liability for the money. 
 Section 2.06. Securityholder Lists. 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar with respect to a Series of Securities, the Company shall furnish to the Trustee any information in the possession or control of the Company (a) on or before each semi-annual interest payment date
of any Series of Securities, and (b) at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Securityholders. 

Section 2.07. Transfer and Exchange. 

When a Security is presented to the Registrar with a request to register a transfer, the Registrar shall register the transfer as requested in
the manner provided in this Section 2.07. 
 Every Security presented or surrendered for registration of transfer or exchange shall (if so
required by the Company or the Registrar) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by the Holder thereof or his attorney duly authorized in writing.
To permit transfers and exchanges, the Company shall execute and the Trustee shall authenticate Securities at the Registrar’s request. The Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be
imposed for any exchange or transfer but not for any exchange pursuant to Section 2.10, 3.06 or 9.05.

 The Company shall not be required: (i) to issue, register the transfer of or exchange Securities
of any Series during a period beginning at the opening of business 15 days before the day of selection for redemption of Securities of that Series under Section 3.02 and ending at the close of business on the day of the mailing of notice of
redemption, or (ii) to register the transfer of, or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

Notwithstanding any provisions to the contrary contained in Section 2.06 of this Indenture and in addition thereto, any Global Security shall
be exchangeable pursuant to this Section 2.07 for Securities registered in the names of Holders other than the Depository for such Security or its nominee only if: (i) such Depository notifies the Company that it is unwilling or unable to continue
as Depository for such Global Security or if at any time such Depository ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and, in either such case, the Company fails to
appoint a successor Depository within 90 days of such event, (ii) the Company executes and delivers to the Trustee an Officers’ Certificate that such Global Security shall be so exchangeable or (iii) a Default shall have occurred and be
continuing with respect to the Securities represented by such Global Security. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Securities registered in such names as the Depository shall direct
in writing in an aggregate principal amount equal to the principal amount of the Global Security with like tenor and terms. 
 Except as
provided in this Section 2.07, a Global Security may not be transferred except as a whole by the Depository with respect to such Global Security to a nominee of such Depository, by a nominee of such Depository to such Depository or another nominee
of such Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository. 
 Section 2.08.
Replacement Securities. 
 If the Holder of a mutilated Security surrenders such Security to the Trustee or if the Holder of a
Security presents evidence satisfactory to the Company and the Trustee that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security of the same Series and of like
tenor and principal amount and bearing a number not contemporaneously outstanding. In case any such Security has or is about to become due and payable, the Company may pay the Security instead of issuing a new Security. If required by the Company or
the Trustee, such Holder shall provide an indemnity bond which must be sufficient in the judgment of the party requiring it to protect the Company, the Trustee and any Agent from any loss which any of them may suffer if a Security is replaced. The
Company or the Trustee may charge the Holder for its expenses in replacing a Security. 
 Every replacement Security is an additional
obligation of the Company.

 Section 2.09. Outstanding Securities. 

Securities outstanding at any time are all the Securities authenticated by the Trustee except for those cancelled by it, those Securities of
any Series for which the Company has made a deposit in accordance with Section 8.01 and those described in this Section as not outstanding. A Security does not cease to be outstanding because the Company or an Affiliate holds the Security. See
Section 10.06. 
 If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof
satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 If the Paying Agent holds on a redemption date or
maturity date money sufficient to pay Securities payable on that date, then on and after that date such Securities cease to be outstanding and interest on them ceases to accrue. 

Section 2.10. Temporary Securities. 

Until definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary
Securities shall be substantially in the form of definitive Securities but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate
definitive Securities in exchange for temporary Securities. 
 Section 2.11. Cancellation. 

The Company at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall destroy such cancelled Securities and
shall furnish the Company with a certificate of destruction. The Company may not issue new Securities to replace Securities that it has paid or delivered to the Trustee for cancellation. 

Section 2.12. Defaulted Interest. 
 If the
Company defaults in the payment of interest on any Series of the Securities, it shall pay the defaulted interest, plus any interest payable on such defaulted interest to the extent permitted by law, to persons who are Holders of Securities of such
Series on a subsequent special record date. The Company shall fix the special record date and the payment date. At least 15 days before such special record date, the Company shall notify the Trustee and each Holder of such special record date, the
payment date and the amount of interest to be paid. The Company may pay defaulted interest in any other lawful manner.

 ARTICLE THREE 

Redemption 
 Section 3.01. Notices to
Trustee. 
 If the Company wants to redeem any Series of Securities pursuant to the terms of the Securities of that Series, the Company
shall notify the Trustee of the redemption date and the principal amount of the Securities to be redeemed. 
 Each such notice shall be
accompanied by an Officers’ Certificate stating that the conditions to such redemption as provided in such Security and in this Indenture have been complied with. If the Company elects to redeem less than all the Securities of a Series, the
Company shall notify the Trustee of such redemption date and of the principal amount of such Securities to be redeemed and shall deliver to the Trustee such documentation and records as shall enable the Trustee to select the Securities to be
redeemed pursuant to Section 3.02. 
 If any Series of Securities by its terms is redeemable pursuant to the operation of a sinking fund,
the Company shall notify the Trustee by an Officers’ Certificate of the amount of the next sinking fund payment and the portion of such payment which is to be satisfied by delivering and crediting Securities of the same Series pursuant to
Section 3.05. 
 If the Company wants to credit against any mandatory redemption Securities of the same Series it has not previously
delivered to the Trustee for cancellation, it shall deliver the Securities with such Officers’ Certificate. 
 The Company shall give
each notice or Officers’ Certificate provided for in this Section at least 30 days before the redemption date (unless shorter notice is satisfactory to the Trustee). 

Any notice of redemption given to the Trustee may be canceled by written notice to the Trustee at any time prior to the mailing of the notice
of redemption to the Holders of Securities to be redeemed and upon any such cancellation shall thereupon be void and of no effect. 
 Section 3.02.
Selection of Securities to be Redeemed. 
 If less than all the Securities of a Series are to be redeemed, the Trustee shall select
the Securities to be redeemed by a method the Trustee considers fair and appropriate. The Trustee shall make the selection from Securities of such Series outstanding not previously called for redemption. The Trustee may select for redemption
portions of the principal of Securities of such Series that have denominations larger than $1,000. Securities and portions of them it selects shall be in amounts of $1,000 or multiples of $1,000. Provisions of this Indenture that apply to Securities
called for redemption also apply to portions of Securities called for redemption. 
 Section 3.03. Notice of Redemption. 

At least 30 days but not more than 60 days before a redemption date, the Company shall mail a notice of redemption by first-class mail (or
deliver by electronic transmission in accordance with the applicable procedures of the Depository) to each Holder of Securities to be redeemed. 

  
 9 

 The notice shall identify the Securities to be redeemed and shall state: 

(1) the redemption date; 

(2) the redemption price (or the method of calculating or determining the redemption price) and the accrued interest, if any;

 (3) the CUSIP number and ISIN, if any, of such Securities; 

(4) if less than all Securities of a Series outstanding are to be redeemed, the identification (and, if any Security is to be
redeemed in part, the principal amount) of the particular Security to be redeemed; 
 (5) the name and address of the Paying
Agent; 
 (6) that Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price;

 (7) that interest on Securities called for redemption ceases to accrue on and after the redemption date; and 

(8) that the redemption is pursuant to a sinking fund, if that is the case. 

At the Company’s request at least five days prior to the date the notice of optional redemption is to be given (unless a shorter time
period shall be acceptable to the Trustee), the Trustee shall give such notice of redemption to each Holder of Securities to be redeemed in the Company’s name and at the Company’s expense. 

Section 3.04. Effect of Notice of Redemption. 

Once notice of redemption is mailed (or delivered by electronic transmission in accordance with the applicable procedures of the Depository),
Securities called for redemption become due and payable on the redemption date and at the applicable redemption price. Upon surrender to the Paying Agent, such Securities shall be paid at the applicable redemption price plus accrued interest, if
any, to the redemption date; provided, however, that any regular payment of interest becoming due on the redemption date shall be payable to the Holders of such Securities in accordance with their terms. 

Section 3.05. Deposit of Redemption Price. 

On or before the redemption date, the Company shall deposit with the Paying Agent (or if the Company is its own Paying Agent, shall segregate
and hold in trust) money sufficient to pay the redemption price of and accrued interest, if any, on all Securities to be redeemed on that date. 

  
 10 

 Unless any Security by its terms prohibits any sinking fund payment obligation from being
satisfied by delivering and crediting Securities (including Securities redeemed otherwise than through a sinking fund), the Company may deliver such Securities to the Trustee for crediting against such payment obligation in accordance with the terms
of such Securities and this Indenture. 
 Section 3.06. Securities Redeemed in Part. 

Upon surrender of a Security that is redeemed in part, the Trustee shall authenticate and deliver to the Holder a new Security of the same
Series equal in principal amount to the unredeemed portion of the Security surrendered.

provided that the Company shall, to the extent lawful, pay interest on overdue installments of interest at the same rate or rates. 
 Section 4.03.
Limitation on Liens. 
 The Company shall not, and it shall not permit any Restricted Subsidiary to, incur a Lien on Restricted
Property to secure a Debt without making effective provision to secure the Securities equally and ratably with such Debt, unless:

Subsidiary; provided, however, that such Lien may not extend to any other Principal Property owned by the Company or a Restricted Subsidiary; 

(2) the Lien is on property at the time the Company or a Restricted Subsidiary acquires or leases the property; provided,
however, that such Lien may not extend to any other Principal Property owned by the Company or a Restricted Subsidiary;

Notwithstanding the provisions of this Section 4.03, the Company or any Restricted Subsidiary may, without equally and ratably securing the
Securities, grant Liens to secure Debt which would otherwise be subject to restriction by this Section 4.03 if, at the time of such granting and after giving effect to any Debt so secured, Exempted Debt does not exceed 15% of Consolidated Net
Tangible Assets.

at the time of entering into the Sale-Leaseback Transaction and after giving effect to it, Exempted Debt does not exceed 15% of Consolidated Net Tangible Assets.

(1) The Company shall deliver to the Trustee within 120 days after the end of each fiscal year of the Company an Officers’ Certificate
stating whether or not the signers know of any Default by the Company in performing its covenants and obligations hereunder that occurred during the fiscal year and is continuing. If the Company knows of such a Default at such time, the Certificate
shall describe the nature and status of the Default. The first such Officers’ Certificate shall be delivered to the Trustee by January 28, 2017. 

(2) The Company shall deliver to the Trustee within ten Business Days following the date on which the Company becomes aware of such Default,
receives notice of such Default or becomes aware of such action, as applicable, an Officers’ Certificate specifying any events which would constitute a Default, their status and what action the Company is taking or proposing to take in respect

 ARTICLE FIVE 

Successor Corporation 
 Section 5.01. When
Company May Merge, etc. 
 The Company may consolidate with or merge into, or transfer all or substantially all of its assets to, one
person or entity if: 
 (1) the person or entity assumes by supplemental indenture all the obligations of the Company under
the Securities and this Indenture; thereafter all such obligations of the predecessor corporation shall terminate; 
 (2)
immediately after giving effect to the transaction, no Default would occur and be continuing; and 
 (3) the entity formed by

 16 

 Section 5.02. When Securities Must Be Secured. 

If upon any such consolidation, merger or transfer any Principal Property would become subject to an attaching Lien that secures Debt, then
before the consolidation, merger or transfer occurs, the Company by supplemental indenture shall secure the Securities by a direct Lien on all such Principal Property. The direct Lien shall have priority over the attaching Lien and over all other
Liens on such Principal Property except the Liens already on it. The direct Lien may equally and ratably secure the Securities and any other obligation of the Company or a Subsidiary entitled to such security. The direct Lien may not secure an
obligation of the Company or such a Subsidiary that is subordinated to the Securities. However, the Company need not comply with this Section if: 

(1) the attaching Lien is permitted under any of clauses (1) through (9) of Section 4.03; or 

(2) the Company or a Restricted Subsidiary under the next to last paragraph of Section 4.03 could create a Lien on the
Principal Property to secure Debt at least equal in amount to that secured by the attaching Lien. 
 ARTICLE SIX 

Defaults and Remedies 
 Section 6.01. Events
of Default. 
 Unless the form of a Security of a Series provides otherwise, an “Event of Default” occurs with respect to
Securities of any Series if: 
 (1) the Company defaults in the payment of interest on any Security of that Series when the
same becomes due and payable and the Default continues for a period of 30 days; 
 (2) the Company defaults in the payment of
the principal of, or premium, if any, on, any Security of that Series when the same becomes due and payable at maturity, upon redemption or otherwise, provided that in the case of default in the making or satisfaction of any sinking fund
payment, such default continues for a period of 30 days; 
 (3) the Company fails to comply with any of its other agreements
in the Securities of that Series or this Indenture (other than a default which has expressly been included in this Indenture solely for the benefit of a Series of Securities other than that Series) and the default continues for the period and after
the notice specified below; 
 (4) an event of default, as defined in any mortgage, indenture or instrument under which there
is or may be issued indebtedness of the Company or any Restricted Subsidiary for money borrowed (including an Event of Default with respect to a Security 

  
 17 

 
of any Series hereunder) in the principal amount exceeding $100,000,000, shall occur with the result that such indebtedness shall have been declared due and payable prior to the date on which it
would otherwise become due and payable, but if any such default is cured by the Company or such Restricted Subsidiary or is waived by the specified percentage of holders of such mortgage, indenture or instrument entitled so to waive, then the Event
of Default under this Indenture by reason of such default shall be deemed to have been cured; 
 (5) the Company, pursuant to
or within the meaning of any Bankruptcy Law: 
 (a) commences a voluntary case; 

(b) consents to the entry of an order for relief from claims against it in an involuntary case; 

(c) consents to the appointment of a Custodian of it or for all or substantially all of its property; or 

(d) makes a general assignment for the benefit of its creditors; 

(6) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that: 

(a) is for relief against the Company in an involuntary case; 

(b) appoints a Custodian of the Company or for all or substantially all of its property; or 

(c) orders the liquidation of the Company; 

and such order or decree remains unstayed and in effect for 90 days; or 

(7) any other Event of Default provided for Securities of that Series occurs. 

A Default with respect to any Series of Securities under clause (3) is not an Event of Default until the Trustee notifies the Company or the
Holders of at least 25% in principal amount of the outstanding Securities of that Series notify the Trustee and the Company of the Default and the Company does not cure the Default within 90 days after receipt of the notice. The notice must specify
the Default, demand that it be remedied and state that the notice is a “Notice of Default.” 
 Section 6.02. Acceleration. 

If an Event of Default with respect to Securities of any Series occurs and is continuing, the Trustee by notice to the Company, or the Holders
of at least 25% in principal amount of the outstanding Securities of that Series by notice to the Company and the Trustee, may declare that the principal of and accrued interest (or, if any of the Securities of that Series are original issue
discount Securities, such portion of the principal amount of such Securities as may be specified 

  
 18 

 
in the terms thereof), if any, shall be due and payable immediately. Upon such declaration, such principal (or specified amount) and interest shall be due and payable immediately. The Holders of
a majority in principal amount of the outstanding Securities of that Series by notice to the Company and the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree and if all
existing Events of Default (other than nonpayment of principal, interest or premium, if any, that has become due solely because of such acceleration) have been cured or waived. 

Notwithstanding any provisions to the contrary contained in this Section 6.02 and in addition thereto, upon receipt by the Trustee of any
declaration of acceleration, or rescission and annulment thereof, with respect to Securities of a Series all or part of which is represented by a Global Security, the Trustee shall establish a record date for determining Holders of outstanding
Securities of such Series entitled to join in such declaration of acceleration, or rescission and annulment, as the case may be, which record date shall be at the close of business on the day the Trustee receives such declaration of acceleration, or
rescission and annulment, as the case may be. The Holders on such record date, or their duly designated proxies, and only such Holders, shall be entitled to join in such declaration of acceleration, or rescission and annulment, as the case may be,
whether or not such Holders remain Holders after such record date; provided, however, that unless such declaration of acceleration, or rescission and annulment, as the case may be, shall have become effective by virtue of the requisite
percentage having been obtained prior to the day which is 90 days after such record date, such declaration of acceleration, or rescission and annulment, as the case may be, shall automatically and without further action by any Holder be cancelled
and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from giving, after expiration of such 90-day period, a new declaration of acceleration, or rescission or annulment thereof, as the case may be, that
is identical to a declaration of acceleration, or rescission or annulment thereof, which has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the provisions of this
Section 6.02. 
 Section 6.03. Other Remedies. 

If an Event of Default with respect to Securities of any Series occurs and is continuing, the Trustee may pursue any available remedy by
proceeding at law or in equity to collect the payment of principal of, interest or premium, if any, on, the Securities of that Series or to enforce the performance of any provision of the Securities of that Series or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Securities of that Series or does not produce any of them in the
proceeding. A delay or omission by the Trustee or any Securityholder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No
remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. 
 Section 6.04. Waiver of Past
Defaults. 
 Subject to Sections 6.07 and 9.02, the Holders of a majority in principal amount of the outstanding Securities or any Series
on behalf of the Holders of the outstanding Securities of that 

  
 19 

 
Series by notice to the Trustee may waive an existing past Default or Event of Default and its consequences but such waiver shall not extend to any future Event of Default. When a Default or
Event of Default is waived by the Holders of any Series of Securities, it is cured and stops continuing with respect to Securities of that Series. 

Section 6.05. Control by Majority. 
 The
Holders of a majority in principal amount of the outstanding Securities of any Series may direct the time, method and place of: (1) conducting any proceeding for any remedy available to the Trustee; or (2) exercising any trust or power conferred on
the Trustee with respect to the Securities of that Series. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture, or subject to Section 7.01, that the Trustee determines would be unduly prejudicial to the
rights of other Securityholders of that Series or that would involve the Trustee in personal liability. 
 Notwithstanding any provisions to
the contrary contained in this Section 6.05, and in addition thereto, upon receipt by the Trustee of any direction with respect to Securities of a Series all or part of which is represented by a Global Security, the Trustee shall establish a record
date for determining Holders of outstanding Securities of such Series entitled to join in such direction, which record date shall be at the close of business on the date the Trustee receives such direction. The Holders on such record date, or their
duly designated proxies, and only such Holders, shall be entitled to join in such direction, whether or not such Holders remain Holders after such record date; provided, however, that unless such majority in principal amount shall have been
obtained prior to the day which is 90 days after such record date, such direction shall automatically and without further action by any Holder be cancelled and of no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of a
Holder from giving, after expiration of such 90-day period, a new direction identical to a direction which has been cancelled pursuant to the proviso to the preceding sentence, in which event a new record date shall be established pursuant to the
provisions of this Section 6.05. 
 Section 6.06. Limitation on Suits. 

A Securityholder may pursue a remedy with respect to this Indenture or the Securities of that Series only if: 

(1) the Holder gives to the Trustee written notice of a continuing Event of Default; 

(2) the Holders of at least 25% in principal amount of the outstanding Securities of that Series make a written request to the
Trustee to pursue the remedy; 
 (3) such Holder or Holders offer to the Trustee indemnity satisfactory to the Trustee
against any loss, liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of
the request and the offer of indemnity; and 

  
 20 

 (5) during such 60-day period the Holders of a majority in principal amount of
the outstanding Securities of that Series do not give the Trustee a direction inconsistent with the request. 
 A Holder of any Series of
Securities may not use any provision of this Indenture to prejudice the rights of another Holder of any Securities of that Series or to obtain a preference or priority over another Holder of any Securities of that Series. 

Section 6.07. Rights of Holders to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of, interest and
premium, if any, on the Security, on or after the respective due dates expressed in the Security, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of
the Holder. 
 Section 6.08. Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(1) or (2) occurs and is continuing for Securities of any Series, the Trustee may recover
judgment in its own name and as Trustee of an express trust against the Company for the whole amount of principal, interest and any premium remaining unpaid on the Securities of that Series. 

Section 6.09. Trustee May File Proofs of Claim. 

The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee and the Holders of Securities of any Series allowed in any judicial proceedings relative to the Company, its creditors or its property. 
 Section
6.10. Priorities. 
 If the Trustee collects any money pursuant to this Article with respect to Securities of any Series, it shall pay
out the money in the following order: 
 FIRST: to the Trustee and any predecessor trustee of the Securities of that Series for amounts due
under Section 7.07; 
 SECOND: to Holders of Securities of that Series for amounts due and unpaid on the Securities of that Series for
principal, interest and premium, if any, ratably without preference or priority of any kind, according to the amounts due and payable on the Securities of that Series for principal, interest and premium, if any, respectively; and 

THIRD: to the Company. 
 The
Trustee may fix a record date and payment date for any payment to Securityholders pursuant to this Section 6.10. 

  
 21 

 Section 6.11. Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted
by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’
fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a
suit by Holders of more than 10% in principal amount of the Securities of any Series.

Trustee 
 Section 7.01. Duties of Trustee.

rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the requirements of this Indenture.

regardless of the form of action in which such damages are sought. 
 (h) The Trustee shall not be responsible or liable for any failure or
delay in the performance of its obligations under this Indenture arising out of or caused, directly or indirectly, by circumstances beyond its reasonable control, including acts of God; earthquakes; fire; flood; terrorism; wars and other military
disturbances; sabotage; epidemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents; labor disputes; acts of civil or military authority and governmental action; provided

(j) The Trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of

(k) The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith and believed by it to be authorized or
within the rights or powers conferred upon it by this Indenture. 
 (l) The Trustee shall not be deemed to have notice of any Default or

 (m) The permissive rights of the Trustee enumerated herein shall not be construed as
duties.

person. The Trustee need not investigate any fact or matter stated in the document.

Indenture, the rights, privileges, protections, immunities and indemnities given to the Trustee are extended to, and shall be enforceable by, the Trustee in its capacity as Registrar, Paying Agent, Custodian or transfer agent hereunder. 

(7) The Trustee may request that the Company deliver an Officers’ Certificate setting forth the names of individuals
and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as
so authorized in any such certificate previously delivered and not superseded; provided that the Trustee may request an updated certificate pursuant to this clause (7) solely in the event that the Trustee reasonably believes that the last such
certificate received from the Company or currently on file is no longer accurate. 
 Section 7.03. Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company or an
Affiliate with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 7.10 and 7.11. 

Section 7.04. Trustee’s Disclaimer. 

The Trustee makes no representation as to the validity or adequacy of this Indenture or the Securities, it shall not be accountable for the
Company’s use of the proceeds from the Securities, and it shall not be responsible for any statement in the Securities other than its certificate of authentication. 

  
 24 

 Section 7.05. Notice of Defaults. 

If a Default occurs and is continuing with respect to Securities of any Series and if it is known to the Trustee, the Trustee shall mail to
each Holder of Securities of that Series notice of the Default within 90 days after it occurs. Except in the case of a Default in payment on any Security of that Series, the Trustee may withhold the notice if and so long as a committee of its
Responsible Officers in good faith determines that withholding the notice is in the interests of Holders of Securities of that Series. 
 Section 7.06.
Reports by Trustee to Holders. 
 Within 60 days after each May 15 beginning with the May 15 following the date of this
Indenture, the Trustee shall mail to the Company and each Securityholder a brief report dated as of such May 15 that complies with TIA Section 313(a). The Trustee shall also comply with TIA Section 313(b). 

A copy of each report at the time of its mailing to Securityholders shall be filed with the SEC and each stock exchange on which the
Securities of any Series are listed. 
 The Company shall notify the Trustee whenever the Securities of any Series are listed on any stock
exchange. 
 Section 7.07. Compensation and Indemnity. 

The Company shall pay to the Trustee from time to time reasonable compensation for its services (which compensation shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust). The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred by it. Such expenses shall include the reasonable compensation
and expenses of the Trustee’s agents and counsel. 
 Except as provided below in this paragraph, the Company shall indemnify each of
the Trustee and any predecessor trustee of the Securities of that Series against any loss or liability incurred by it in connection with the administration of the trust created by this Indenture or the performance of its duties hereunder, including
all reasonable costs and expenses in defending itself against any claim or liability in connection with the exercise or performance of any of its powers and duties under this Indenture. The Trustee shall notify the Company promptly of any claim for
which it may seek indemnity but failure to do so shall not relieve the Company of its obligations under this Section 7.07. The Company need not pay for any settlement made by the Trustee without the Company’s consent. The Company need not
reimburse any expense or indemnify against any loss or liability incurred by either the Trustee or any predecessor trustee of the Securities of that Series through its own negligence or bad faith. In respect of the Company’s payment obligations
in this Section 7.07, the Trustee shall have a senior claim to which the Securities are hereby made subordinate on all money or property held or collected by the Trustee as such and not in its individual capacity, except for money or property held
in trust for the benefit of the Holders to pay the principal of and interest and premium, if any, on particular Securities. 

  
 25 

 Section 7.08. Replacement of Trustee. 

The Trustee may resign with respect to any or all Series of Securities by so notifying the Company. The Holders of a majority in principal
amount of the outstanding Securities or any Series may remove the Trustee with respect to the Securities of that Series by notifying the removed Trustee and the Company. Those Holders may appoint a successor Trustee with respect to the Securities of
that Series with the Company’s consent. The Company may remove the Trustee with respect to any or all Series of Securities or, if there is more than one Trustee hereunder, with respect to all Series of Securities for which such Trustee acts as
Trustee if: 
 (1) the Trustee fails to comply with Section 7.10; 

(2) the Trustee is adjudged a bankrupt or an insolvent; 

(3) a receiver or public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 

If the Trustee with respect to one or more Series of Securities resigns or is removed or if a vacancy exists in the office of Trustee for any
reason, the Company shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in principal amount of the Securities may appoint a successor Trustee to replace the successor
Trustee appointed by the Company. 
 If a successor Trustee with respect to one or more Series of Securities does not take office within 60
days after the retiring Trustee resigns or is removed, the retiring Trustee, the Company or the Holders of a majority in principal amount of the Securities with respect to such Series of Securities may petition any court of competent jurisdiction
for the appointment of a successor Trustee. 
 If the Trustee fails to comply with Section 7.10, any Securityholder may petition any court
of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 
 A successor Trustee shall deliver a
written acceptance of its appointment to the retiring Trustee and to the Company. 
 Immediately after that, the retiring Trustee shall
transfer all property held by it as Trustee to the successor Trustee, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture with respect to the Securities of any Series for which it acts as Trustee. A successor Trustee shall mail notice of its succession to each Holder of Securities of a Series for which it acts as Trustee. 

  
 26 

 If at the time a successor to the Trustee succeeds to the trusts created by this Indenture any of
the Securities of any Series shall have been authenticated but not delivered, the successor to the Trustee of the Securities of that Series may adopt the certificate of authentication of any predecessor trustee for that Series of Securities and
deliver the Securities for that Series so authenticated. If at that time any of the Securities of a Series shall not have been authenticated, any successor to the Trustee for that Series of Securities may authenticate the Securities for that Series
either in the name of any predecessor trustee for that Series of Securities hereunder or in the name of the successor Trustee. In all such cases the certificate of authentication shall have the same force and effect which the provisions of the
Securities or this Indenture provided that certificates of authentication of the Trustee shall have, except that the right to adopt the certificate of authentication of any predecessor trustee for a Series of Securities or to authenticate Securities
of a Series in the name of any predecessor trustee for that Series of Securities shall apply only to its successor or successors by merger, conversion or consolidation. 

Section 7.09. Successor Trustee by Merger, etc. 

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust assets to, another
corporation, the successor corporation shall be the successor Trustee, without any further act. 
 Section 7.10. Eligibility Disqualification. 

This Indenture shall always have for each Series of Securities a Trustee who satisfies the requirements of TIA Section 310(a)(l). The Trustee
shall always have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. If any Series of Securities is admitted to trading on the New York Stock Exchange, Inc., or any successor
thereto, the Company shall ensure that a transfer agent facility maintain an office or agency in the Borough of Manhattan, the City of New York, as long as such Series of Securities shall be so admitted. With respect to each Series of Securities,
the Trustee shall comply with TIA §310(b), including the proviso contained in TIA §310(b)(1) and the optional provision permitted by the second sentence of TIA §310(b)(9). 

Section 7.11. Preferential Collection of Claims Against Company. 

The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who has resigned
or been removed shall be subject to TIA Section 311(a) to the extent indicated. 
 ARTICLE EIGHT 

Discharge of Indenture 
 Section 8.01.
Termination of Company’s Obligations. 
 The Company at any time may terminate its obligation to pay an installment
of principal and premium, if any, or interest if it deposits with the Trustee money or U.S. Government Obligations sufficient to pay the installment when due. The Company shall designate the installment for which payment is being made. 

  
 27 

 The Company at any time may terminate all of its obligations under the Securities of any or all
Series and this Indenture with respect to such Series or all Series if: 
 (1) all Securities of such Series previously
authenticated and delivered (other than destroyed, lost or stolen Securities of such Series which have been replaced or paid) have been delivered to the Trustee for cancellation; or 

(2) the Company irrevocably deposits in trust with the Trustee money or U.S. Government Obligations (a) sufficient to pay the
principal of, and interest and premium, if any, on the Securities of such Series to maturity or redemption, as the case may be, or (b) in the case of a Series of Securities which provides for a mandatory sinking fund, sufficient to make all
mandatory sinking fund payments to maturity and sufficient to pay at maturity any principal of and interest on such Series for Securities of such Series not redeemed prior to maturity (other than monies paid to the Company or discharged from trust
in accordance with Section 8.03). 
 However, the Company’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 4.02, 7.07, 7.08 and
8.03 with respect to the Securities of such Series shall survive until the Securities of such Series are no longer outstanding. Thereafter the Company’s obligations in Section 7.07 shall survive. 

After such a deposit, the Trustee upon request shall acknowledge, in writing, the discharge of the Company’s obligations under the
Securities of such Series and this Indenture except for those surviving obligations specified above. 
 In order to have money available on
a payment date to pay principal of, and interest or premium, if any, on, the Securities, the U.S. Government Obligations shall be payable as to principal of, interest or premium, if any, on or before such payment date in such amounts as will provide
the necessary money. U.S. Government Obligations shall not be callable at the issuer’s option. 
 Section 8.02. Application of Trust Money. 

The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to Section 8.01. It shall apply the deposited
money and the money from U.S. Government Obligations through the Paying Agent in accordance with this Indenture to the payment of principal of, interest and premium, if any, on, the Securities of the Series or to the payment of any mandatory sinking
fund payments, for which the money or U.S. Government Obligations have been deposited. 
 Section 8.03. Repayment to Company. 

The Trustee and the Paying Agent shall promptly pay to the Company upon request any excess money or U.S. Government Obligations held by them at
any time. The Trustee and Paying Agent shall pay to the Company upon request any money or U.S. Government Obligations held by them for the payment of principal, interest or premium, if any, on any Security or for the payment of any mandatory sinking
fund payments, that remains unclaimed for two years after such principal, interest, premium or mandatory sinking fund payments have 

  
 28 

 
become due and payable. If such money or U.S. Government Obligations are then held by the Company they shall be discharged from the trust. After that, Securityholders entitled to the money must
look to the Company for payment as unsecured general creditors unless an applicable abandoned property law designates another person or entity. 

ARTICLE NINE 
 Amendments,
Supplements and Waivers 
 Section 9.01. Without Consent of Holders. 

The Company and the Trustee may amend or supplement this Indenture or the Securities without notice to or consent of any Securityholder: 

(1) to cure any ambiguity, omission, defect or inconsistency or to make other formal changes; 

(2) to comply with Article Four or Five; 

(3) to provide for uncertificated Securities in addition to or in place of certificated Securities; 

(4) to add to the covenants of the Company or to add any additional Events of Default for the benefit of all or any Series of
Securities; 
 (5) to add to or change any of the provisions of this Indenture to such extent as shall be necessary to permit
or facilitate the issuance of Securities in (i) bearer form, registrable or not registrable as to principal, and/or (ii) coupon form, registrable or not registrable as to principal, and to provide for exchangeability of such Securities with
Securities issued hereunder in fully registered form; 
 (6) to add to or change any provisions of this Indenture as shall be
necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; 
 (7) to
establish the form or terms of the Securities of any Series pursuant to Section 2.01; 
 (8) to make any change that does not
adversely affect the rights of any Securityholder, provided that none of such changes shall adversely affect the rights of any Securityholder; 

(9) to modify or amend this Indenture in such a manner as to permit the qualification of this Indenture or any supplemental
indenture under the TIA as then in effect; 
 (10) to conform any provision in this Indenture and any supplemental indenture
to the description of any Securities in an offering document; 

  
 29 

 (11) to add guarantees with respect to the Securities or to secure the
Securities; or 
 (12) to provide for the issuance of additional debt securities of any Series. 

Section 9.02. With Consent of Holders. 

The Company and the Trustee may amend this Indenture or the Securities without notice to any Securityholder but with the written consent of the
Holders of at least a majority in principal amount of the outstanding Securities of each Series affected by such indenture supplement or amendment (each Series voting separately as one class). The Holders of a majority in principal amount of the
outstanding Securities of each such Series (each Series voting separately as one class) may waive compliance by the Company in a particular instance with any provision of this Indenture or the Securities of such Series without notice to any Holder
of Securities of such Series. Without the consent of each Securityholder affected, however, an amendment, supplement or waiver, including a waiver pursuant to Section 6.04, may not: 

(1) reduce the amount of Securities whose Holders must consent to an amendment, supplement or waiver; 

(2) reduce the rate of or change the time for payment of interest on any Security; 

(3) reduce the principal of or change the fixed maturity of any Security; 

(4) waive a default in the payment of the principal of or premium, if any, or interest on any Security; 

(5) make any Security payable in money other than that stated in the Security; or 

(6) change the provisions applicable to the redemption of any Security. 

It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed supplement, but it
shall be sufficient if such consent approves the substance thereof. 
 Section 9.03. Compliance with Trust Indenture Act. 

Every amendment to or supplement of this Indenture or the Securities shall comply with the TIA as then in effect. 

Section 9.04. Revocation and Effect of Consents. 

A consent to an amendment, supplement or waiver by a Holder of a Security of any Series is a continuing consent, irrevocable for a period of
nine months from the date given or, if earlier, until the amendment, supplement or waiver becomes effective, both as to the Holder giving such consent and as to every subsequent Holder of a Security of that Series or a portion of

  
 30 

 
such a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on each Security of that Series. An amendment, supplement or
waiver becomes effective in accordance with its terms and thereafter binds every Securityholder of that Series. 
 Section 9.05. Notation on or Exchange
of Securities. 
 If an amendment, supplement or waiver changes the term of a Security, the Trustee may require the Holder of the
Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security about an amendment, supplement or waiver and return it to the Holder. Alternatively, the Company in exchange for Securities may issue and the
Trustee shall authenticate new Securities that reflect an amendment, supplement or waiver. 
 Section 9.06. Trustee to Sign Amendments, etc. 

The Trustee need not sign any supplemental indenture that adversely affects its rights. In signing such amendment, supplement or waiver, the
Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in relying upon, an Officers’ Certificate and Opinion of Counsel stating that such amendment, supplement or waiver is authorized or permitted by this
Indenture.

Series include those stated in this Security, in the Indenture and those made part of the Indenture by reference to the TIA. The Securities of this Series are subject to all such terms and Holders are referred to this Security, the Indenture and the

exchange any Security for a period beginning 15 days before the selection of Securities to be redeemed and ending on the day of a mailing of the notice of redemption. 

[    ] Persons Deemed Owners. [If applicable, insert] 

The registered Holder of a Security may be treated as the owner of it for all purposes, except as otherwise provided in paragraph 2 of this
Security. 
 [    ] Unclaimed Money. 

If money for the payment of principal or interest remains unclaimed for two years, the Trustee or Paying Agent will pay the money back to the
Company at its request. After that, Holders entitled to the money must look to the Company and not to the Trustee for payment unless an abandoned property law designates another person. 

[    ] Amendments, Supplements and Waivers. 

Subject to certain exceptions, the Indenture or the Securities of any Series may be amended or supplemented and compliance with any provisions

determines that withholding notice is in their interests. 
 [    ] Trustee Dealings with Company. 

The Trustee, in its individual or any other capacity, may make loans to, accept deposits from and perform services for the Company or its
Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee. 
 [    ] No Recourse Against
Others.

Company under the Security of any Series or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release
are part of the consideration for the issue of the Security.

NOW, THEREFORE, in
consideration of the mutual covenants, conditions and agreements set forth herein, and for such other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

 

1.          Right

as required thereunder. Medical Center acknowledges that GKF is a third party beneficiary of the LGK Agreement and, in that capacity,
GKF shall be entitled to enforce Medical Center’s performance, satisfaction and fulfillment of its obligations thereunder.

 

     

     

    

 

3.          Term
of the Agreement. The initial term of this Agreement (the “Term”) shall commence as of the date hereof and, unless
earlier terminated or extended in accordance with the provisions of this Agreement, shall continue for a period of seven (7) years
following the date of the performance of the first clinical Procedure (as defined in Section 8) performed on the Equipment (the
“First Procedure Date”) at the Site (as defined in Section 5.1).  The parties agree to amend this Agreement
to memorialize the First Procedure Date upon the performance of the first clinical Procedure performed on the Equipment. Medical
Center’s obligation to make the “Purchased Services Payments” to GKF for the Equipment described in Section 8
below shall commence as of the First Procedure Date.

 

4.          User
License. Medical Center shall apply for and use its reasonable efforts to obtain in a timely manner a User License from the Nuclear
Regulatory Commission and, if necessary, from the applicable state agency authorizing it to take possession of and maintain the
Cobalt supply required in connection with the use of the Equipment during the term of this Agreement. Medical Center also shall
apply for and use its reasonable efforts to obtain in a timely manner all other licenses, permits, approvals, consents and authorizations
which may be required by state or local governmental or other regulatory agencies for the development, construction and preparation

5.1           GKF
shall coordinate with Elekta and Medical Center to have the Equipment delivered to Medical Center at the site at which the Model
B is currently located, as described in Exhibit 5.1 of this Agreement (the “Site”), which delivery is anticipated to
be on or before July 2009, subject to all approvals and User Licenses having been obtained, and provided that, if such delivery
date is in advance of the expiration of the current term of the existing Lease Agreement For A Gamma Knife Unit dated June 1, 1998,
between GKF and Medical Center (as amended, the “Prior Agreement”), which results in an early termination of the Prior
Agreement, then, the parties will negotiate an extension to the Term of this Agreement to offset the effect of such early termination
of the Prior Agreement. GKF makes no representations or warranties, and assumes no responsibility or liability, concerning
delivery of the Equipment to the Site or the actual date thereof. Medical Center shall bear no risk of loss prior to actual delivery
of Equipment to the Site.

 

    - 2 - 

     

    

 

5.2           Medical
Center shall provide access to the Site for the Equipment. GKF at its cost and expense shall prepare the Site for the Equipment
in accordance with Elekta’s guidelines, specifications, technical instructions and site planning criteria (which site planning
criteria are attached as Exhibit 5.2 of this Agreement) (collectively the “Site Planning Criteria”). The location of
the Site has been agreed upon by Medical Center and GKF as described in Exhibit 5.1 of this Agreement.

 

		6.	Site Preparation, Deinstallation of Model B and Installation
of Equipment.

 

6.1           GKF,
at its cost, expense and risk, shall prepare all plans and specifications required to construct and improve the Site for the installation,
use and operation of the Equipment during the Term. The plans and specifications shall comply in all respects with the Site Planning
Criteria and with all applicable federal, state and local laws, rules and regulations. All plans and specifications prepared by
or on behalf of GKF (and all material changes thereto following approval by Medical Center and Elekta) shall be subject to the
written approval of Medical Center and Elekta prior to commencement of construction at the Site. GKF shall provide Medical Center
and Elekta with a reasonable period of time for the review and consideration of all plans and specifications following the submission
thereof for approval (and Medical Center shall not unreasonably withhold or delay its approval). Following approval of the plans
and specifications by Medical Center and Elekta, GKF, at its cost and expense, shall assist Medical Center in obtaining all permits,
certifications, approvals or authorizations required by applicable federal, state or local laws, rules or regulations necessary
to construct and improve the Site for the installation, use and operation of the Equipment.

 

6.2           Based
upon the plans and specifications approved by Medical Center and Elekta, GKF, at its cost, expense and risk, shall prepare, construct
and improve the Site as necessary for the installation, use and operation of the Equipment during the Term, including, without
limitation, providing all temporary or permanent shielding required for the charging of the Equipment with the Cobalt supply and
for its subsequent use, selecting and constructing a proper foundation for the Equipment and the temporary or permanent shielding,
aligning the Site for the Equipment, and installing all electrical systems and other wiring required for the Equipment. In connection
with the construction of the Site, GKF, at its cost and expense, shall select, purchase and install all radiation monitoring equipment,
devices, safety circuits and radiation warning signs required, if any, at the Site in connection with the use and operation of
the Equipment, all in accordance with applicable federal, state and local laws, rules, regulations or custom.

 

    - 3 - 

     

    

  

6.3           GKF,

6.4           GKF
warrants and ensures that, to its best knowledge, upon completion of the preparation, construction and improvement of the
Site, including the positioning of the Equipment on its foundation at the Site and installation of the Equipment, the Site shall
comply in all material respects with the Site Planning Criteria and all applicable federal, state and local laws, rules and regulations,
and be safe and suitable for the ongoing use and operation of the Equipment during the Term. GKF agrees to indemnify, defend and
hold Medical Center harmless from any loss, or claim, suit or proceeding brought against the Medical Center in connection with
or arising from GKF’s noncompliance with GKF’s warranties and assurances provided under this Section 6.4. It is acknowledged
that the existing site and location that are currently being used for the Model B pursuant to the Prior Agreement (the “Existing
Site”) will continue to be used for the Equipment following the deinstallation and removal of the Model B and GKF’s
modifications to the Site to accommodate the Equipment. Notwithstanding anything to the contrary contained in this Agreement, (a)
nothing set forth in this Agreement shall eliminate, modify or limit any or all of Medical Center’s representations, warranties
and/or obligations set forth in the Prior Agreement with respect to the Existing Site, all of which shall remain unchanged and
in full force and effect, and shall survive the termination or expiration of the Prior Agreement; and (b) GKF makes no representation
or warranty and assumes no liabilities with respect to the work performed by or on behalf of Medical Center pursuant to the Prior
Agreement in connection with the Existing Site.

 

6.5           GKF
at its cost, expense and risk, shall coordinate with Elekta the deinstallation and removal of the Model B including unloading and
disposing of the cobalt. GKF agrees to provide Medical Center the option to retain its existing headframes and fiducial boxes;
and in the event that Medical Center exercises this option, GKF also agrees that it shall, at its sole cost and expense, refurbish
the existing headframes.

 

6.6           GKF
shall use its reasonable efforts to satisfy its obligations under this Section 6 in a timely manner. GKF shall keep Medical Center
informed on a regular basis of its progress in the design of the Site, the preparation of plans and specifications, the construction
and improvement of the Site, and the satisfaction of its other obligations under this Section 6. In all events, GKF shall complete
all construction and improvement of the Site required for the installation, positioning and testing of the Equipment on or prior
to the delivery date described in Section 5.1 above. During the Term, Medical Center, at its cost and expense, shall maintain the
Site in a good working order, condition and repair, reasonable wear and tear excepted.

 

    - 4 - 

     

    

  

6.7           Notwithstanding
anything to the contrary contained in this Agreement, GKF’s responsibility for all costs and expenses incurred in connection
with Section 6.1, 6.2, and 6.3 shall not exceed One Hundred Fifty-Two Thousand Dollars ($152,000.00) in the aggregate. All costs
and expenses in excess of One Hundred Fifty-Two Thousand Dollars ($152,000.00) shall be the responsibility of Medical Center.

 

7.          Marketing
Support. GKF, in coordination with Medical Center, shall provide Medical Center with marketing support for the service to be
provided by Medical Center using the Equipment. Not less than ninety (90) days prior to the First Procedure Date and the commencement
of each succeeding twelve (12) month period during the Term, GKF and Medical Center shall develop a mutually agreed upon marketing
budget and plan (“Plan”) for the clinical service to be supported by the Equipment for the succeeding twelve (12) month
period of the Term. Once approved, the Plan shall be implemented by Medical Center in accordance with its terms. If Medical Center
has not approved or disapproved of the Plan within sixty (60) days following its receipt, Medical Center shall be deemed to have
approved the same. All advertisements, brochures and other marketing materials pertaining to the Plan shall be subject to review
and written approval by Medical Center and GKF prior to their use. Medical Center and GKF shall discuss the Plan on a regular basis
not less than once per quarter. Medical Center’s and any Medical Center subsidiary’s or related corporation’s
name, trademarks, service marks, or other identifying names, marks, images or designations shall be and remain the sole and exclusive
property of Medical Center, but which may be used in any written pre-approved marketing materials without payment of any license
or royalty fee. As funds are expended by Medical Center in accordance with the Plan, Medical Center shall submit invoices (together
with documentary evidence supporting the invoices) for its expenditures paid to third parties and, promptly following the receipt
of such invoices, GKF shall reimburse Medical Center for fifty percent (50%) of approved expenditures, provided that such portion
to be reimbursed by GKF shall not exceed an average of Seventy-Five Thousand Dollars ($75,000) annually during the term of the
Agreement. It is acknowledged by the parties that such expenses to be reimbursed by GKF as provided in Section 7 have been included
in GKF’s calculation of Medical Center’s Purchased Services Payments so as to allow GKF to recover such GKF expenses
during the Term of this Agreement.

 

		8.	Purchased Services Payments.

 

(a)          The
parties have negotiated this Agreement at arm’s length based upon reasonable and jointly derived assumptions regarding the
capacity for clinical services available from the Equipment, Medical Center’s capabilities in providing high quality radiation
oncology services, market dynamics, GKF’s risk in providing the Equipment, and the provision to GKF of a reasonable rate
of return on its investment in support of the Equipment. Based thereon, the Parties believe that the “Purchased Services
Payments” as defined below represent fair market value for the use of the Equipment, the deinstallation and removal of the
Model B, the preparation, construction and improvement of the Site, and the marketing support and other services to be provided
by GKF to Medical Center hereunder. Medical Center undertakes no obligation to perform any minimum number of Procedures on the
Equipment, and the use of the Equipment for the performance of Procedures is wholly based upon the independent judgment of physicians
who order such Procedures to meet the medical needs of their patients.

 

    - 5 - 

     

    

 

(b)          In
consideration for and as compensation to GKF for deinstallation and removal of the Model B, the preparation, construction and improvement
of the Site, installation and use of the Equipment, the Equipment modification allowance referenced in Section 13.1 below, and
marketing support and the other additional services to be provided by GKF under this Agreement, Medical Center shall pay to GKF,
on a monthly basis, the applicable “Purchased Services Payments” (as defined below) for each "Procedure"
that is performed by Medical Center or its representatives or affiliates, whether on an inpatient or outpatient basis, and irrespective
of whether the Procedure is performed on the Equipment or using any other equipment or devices, including but not limited to any
“Additional GK Leksell Unit” (defined below). Notwithstanding the foregoing, and for the avoidance of doubt, if at
any time in addition to the Equipment, Medical Center purchases, leases or otherwise acquires from any third party the use of a
Leksell Gamma Knife unit(s) of any model type or configuration (an “Additional GK Leksell Unit”), then, in addition
to the Purchased Services Payments that are payable to GKF for Procedures performed using the Equipment as set forth above, Medical
Center shall pay to GKF the Purchased Services Payments on a monthly basis for any and all Procedures performed using the Additional
GK Leksell Unit, and/or any other equipment or devices, whether on an inpatient or outpatient basis. The parties acknowledge that
the Purchased Services Payments represent fair market value for the use of the Equipment as described in this Agreement. As used
herein:

 

(i)          "Procedure"
means any treatment that involves stereotactic, external, single fraction, conformal radiation, commonly called radiosurgery, that
may include one or more isocenters during the patient treatment session, delivered to any site(s) superior to the foramen magnum.
“Procedure” shall expressly exclude (1) any procedures which the Equipment is unable to perform or which, in the opinion
of Elekta, the Equipment is not designed or reasonably suitable to perform; and/or (2) any fractionated procedures for a single
tumor involving more than a single fraction (commonly called fractionated stereotactic radiotherapy) where such fractionated treatment
is medically indicated.

 

(ii)         “Purchased
Services Payments” shall be equal to the applicable percentage of the “Technical Component Collections” relating
to each Procedure as set forth in Exhibit 8 attached hereto performed using the Equipment, any Additional GK Leksell Unit and/or
any other equipment or devices during the Term of this Agreement.

 

    - 6 - 

     

    

 

(iii)        “Technical
Component Collections” means the total amount actually collected by Medical Center or its representatives or affiliates during
each month from any and all payor sources, including, without limitation, patients, insurance companies, state or federal government
programs or any other third party payors, including, without limitation, all copayments and deductibles, as reimbursement for the
technical component of all services (including, but not limited to, treatment planning and delivery, imaging, medical supplies,
pharmacy, laboratory, and recovery room) pertaining to each Procedure performed on the Equipment, any Additional GK Leksell Unit
and/or any other equipment or devices during the term of this Agreement. The technical fees to be billed for each Procedure (on
an individual basis and not collectively) that is performed utilizing the Equipment, any Additional GK Leksell Unit and/or any
other equipment or devices during the Term of this Agreement shall be an amount which is economically justifiable based upon GKF’s
direct operating expenses and its total project costs, together with a return thereon. For all Procedures that are performed utilizing
the Equipment, any Additional GK Leksell Unit and/or any other equipment or devices, Medical Center shall consult in advance with
GKF from time to time regarding the amount of such technical fees to be billed by Medical Center. Subject to compliance with the
standard described in the preceding sentence, Medical Center and GKF shall mutually agree on the setting or revision of the amount
of, or portion comprising, such technical fees on no more than an annual basis to ensure that such fees remain consistent with
fair market value, and the acceptance of the technical fee component amounts with third party payors prior to their implementation.

 

(c)          On
or before the fifteenth (15) day and the last day of each month (or portion thereof) during the term of this Agreement, Medical
Center shall inform GKF in writing as to (i) the number of Procedures performed during that month utilizing the Equipment (and,
if applicable, any Additional GK Leksell Unit and/or any other equipment or devices); and (ii) the Technical Component Collections
during that month. Medical Center shall submit claims for reimbursement to the appropriate payors for each Procedure within thirty
(30) days after the patient receiving the treatment is discharged. If no Technical Component Collections are received during any
month, then, no Purchased Services Payments shall be owing by Medical Center to GKF for that month. During the Term of this Agreement,
Medical Center shall, by the thirtieth (30th) day of each month, remit GKF’s aggregate Purchased Services Payment for the
immediately preceding month, and, for a period of twenty-five (25) months following the termination or expiration of this Agreement
(the “Collections Run-Out Period”), Medical Center shall, by the thirtieth (30th) day of each such month, continue
to remit GKF’s aggregate Purchased Services Payment pertaining to Technical Component Collections received during the Collections
Run-Out Period as applicable to Procedures performed during the Term. All or any portion of a Purchased Services Payment which
is not paid in full within sixty (60) days after its due date shall bear interest at the rate of one percent (1%) per month (or
the maximum monthly interest rate permitted to be charged by law between an unrelated, commercial borrower and lender, if less)
until the unpaid Purchased Services Payment together with all accrued interest thereon is paid in full. If GKF shall at any time
accept a Purchased Services Payment from Medical Center after it shall become due, such acceptance shall not constitute or be construed
as a waiver of any or all of GKF’s rights under this Agreement, including the rights of GKF set forth in Section 20 hereof.

 

    - 7 - 

     

    

 

(d)          Within
thirty (30) days after the close of each month, Medical Center shall provide GKF with a patient de-identified written report indicating
the status of billings and collections for each Procedure performed during that month using the Equipment, any Additional GK Leksell
Unit and/or any other equipment or devices, including, without limitation, the amount of the claim submitted and the amount received
for each such Procedure. Upon request by GKF, Medical Center shall furnish to GKF information regarding reimbursement rates from
any or all payor sources for Procedures (applicable to procedures performed either on an inpatient or outpatient basis). If such
reimbursement rates should change at any time or from time to time after the date hereof, in each instance, Medical Center shall
provide written notice thereof to GKF within five (5) days of Medical Center receiving notice thereof.

 

(e)          Within ten
(10) days after Medical Center’s receipt of written request by GKF, GKF shall have the right to audit all applicable books
and records during normal business hours to verify the number of Procedures performed and Technical Component Collections received
by Medical Center or its agents, representatives or affiliates, utilizing the Equipment, any Additional GK Leksell Unit and/or
any other equipment or devices, and Medical Center shall provide GKF (or cause GKF to be provided) with access to such books and
records; provided that any patient names or identifiers or other confidential and Protected Health Information (as defined and
required by state and federal law) shall not be disclosed.

 

(f)          The
provisions of this Section 8 shall survive the termination or expiration of this Agreement.

12.1         During
the Term and except as otherwise provided in this Agreement, GKF, at its cost and expense, shall (a) maintain the Equipment in
good operating condition and repair, reasonable wear and tear excepted, and (b) maintain in full force and effect an Advanced Service
Agreement with Elekta (“Service Agreement”) and any other service or other agreements required to fulfill GKF’s
obligation to repair and maintain the Equipment under this Section 12. Medical Center shall promptly notify GKF in the event of
any damage or destruction to the Equipment or of any required maintenance or repairs to the Equipment, regardless of whether such
repairs or maintenance are covered or not covered by the Service Agreement. GKF shall pursue all remedies available to it under
the Service Agreement and under any warranties made by Elekta with respect to the Equipment so that the Equipment will at all times
during the Term of this Agreement be free from defects in design, materials and workmanship and will conform to Elekta’s

    - 10 - 

     

    

  

12.2         GKF
and Elekta shall have the right to access the Equipment for the purpose of inspection and the performance of repairs at all reasonable

Center shall be liable for, and in the manner described in Section 22 below shall indemnify GKF from and against, any damage to
or destruction of the Equipment caused by the misuse, improper use, or other intentional and wrongful or negligent acts or omissions
of Medical Center’s officers, employees, agents, contractors and physicians. In the event the Equipment is damaged
as a result of the misuse, improper use, or other intentional and wrongful or negligent acts or omissions of Medical Center’s
officers, employees, agents, contractors and/or physicians, to the extent such damage is not covered by the Service Agreement or
any warranties or insurance, GKF may service or repair the Equipment as needed and the cost thereof shall be paid by Medical Center
to GKF immediately upon written request together with interest thereon at the rate of one percent (1%) per month (or the maximum
monthly interest rate permitted to be charged by law between an unrelated, commercial borrower and lender, if less) and reasonable

		13.	Alterations and Upgrades to Equipment.

 

13.1         Medical
Center shall not make any modifications, alterations or additions to the Equipment (other than normal operating accessories or
controls) without the prior written consent of GKF. Medical Center shall not, and shall not permit any person other than representatives
of Elekta or any other person authorized by GKF to, effect any inspection, adjustment, preventative or remedial maintenance, or
repair to the Equipment without the prior written consent of GKF. All modifications, alterations, additions, accessories or operating
controls incorporated in or affixed to the Equipment (herein collectively called “additions” and included in the definition
of “Equipment”) shall become the property of the GKF upon termination of this Agreement. Included in this Agreement
is an Equipment modification allowance of Two Hundred Thousand Dollars ($200,000.00) for modifications that are mutually agreed
upon by the parties hereto. Equipment modification costs in excess of Two Hundred Thousand Dollars ($200,000.00) shall be the responsibility

source (i.e., on or around the end of the fifth (5th) year of the Term), and (b) GKF pays the reload costs associated
therewith up to Nine Hundred Thousand Dollars ($900,000), then, notwithstanding any provisions to the contrary herein, the initial
Term shall be automatically extended for an additional three (3) years. Cobalt-60 reload costs in excess of Nine Hundred Thousand
Dollars ($900,000) shall be the responsibility of Medical Center. Alternatively, Medical Center may elect to pay the entire costs
of the Cobalt-60 reload in which case the Term of the Agreement shall remain unchanged.

 

13.3         All
software upgrades provided at no charge to GKF under the terms of its maintenance agreement with Elekta shall be provided at no
charge to Medical Center. All other software upgrades shall be the responsibility of Medical Center, and shall not be included

a capitalized lease or other commercially available debt or financing instrument. If GKF finances the Equipment through an installment
loan, GKF shall be required to provide the Equipment as collateral for the loan. If GKF finances the Equipment through a capitalized
lease, title shall vest with the lessor until such time as GKF exercises its buy-out option under the lease, if any. If required
by the lender, lessor or other financing entity (the “Lender”), GKF may assign its interest under this Agreement as
security for the financing. Medical Center’s interest under this Agreement shall be subordinate to the interests of the Lender.

professionals, and technical and support personnel, supplies and other items required to properly operate the Equipment and perform
Procedures.

 

16.         Taxes.
GKF shall pay all sales or use taxes imposed or assessed in connection with the use or purchase of the Equipment and all
personal property taxes imposed, levied or assessed on the ownership and possession of the Equipment during the Term. Unless Medical
Center provides GKF with a tax exemption certificate, all other taxes, assessments, licenses or other charges imposed, levied or
assessed on the Equipment during the Term for which Medical Center is not expressly exempt, shall be paid by Medical Center before
the same shall become delinquent, whether such taxes are assessed or would ordinarily be assessed against GKF or Medical Center;
provided, however, Medical Center shall not be required to pay any federal, state or local income, franchise, corporation or excise
taxes imposed upon GKF's net income realized from the Purchased Services Payments of the Equipment. In case of a failure by either
party to pay any taxes, assessments, licenses or other charges when and as required under this Section, the other party may pay
all or any part of such taxes, in which event the amount paid by such paying party shall be immediately payable to the paying party
upon written request together with interest thereon at the rate of at the rate of one percent (1%) per month (or the maximum monthly
interest rate permitted to be charged by law between an unrelated, commercial borrower and lender, if less).

 

17.         No
Warranties by GKF. Medical Center warrants that as of the First Procedure Date, it shall have (a) thoroughly inspected the
Equipment to the best of their knowledge, (b) determined that to the best of its knowledge the Equipment is consistent
with the size, design, capacity and manufacture selected by it, and (c) satisfied itself that to the best of its knowledge
the Equipment is suitable for Medical Center intended purposes and is good working order, condition and repair. GKF will work
with Medical Center in good faith to remedy any problems identified in writing by Medical Center during Medical
Center's inspection. GKF SUPPLIES THE EQUIPMENT UNDER THIS AGREEMENT IN ITS “AS IS” CONDITION. GKF, NOT BEING
THE MANUFACTURER OF THE EQUIPMENT OR THE MANUFACTURER’S AGENT, MAKES NO WARRANTY OR REPRESENTATION, EITHER EXPRESSED OR
IMPLIED, AS TO THE EQUIPMENT’S MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR USE, DESIGN, CONDITION, DURABILITY,
CAPACITY, MATERIAL OR WORKMANSHIP OR AS TO PATENT INFRINGEMENT OR THE LIKE. As between GKF and Medical Center, Medical Center
shall bear all risks with respect to the foregoing warranties. Notwithstanding the foregoing, GKF shall use its best efforts
to ensure that all benefits under the manufacturer’s warranty shall run to the Medical Center. GKF shall not be liable
for any direct, indirect and consequential losses or damages suffered by Medical Center or by any other person, and Medical
Center expressly waives any right to hold GKF liable hereunder for, any claims, demands and liabilities arising out of or in
connection with the design, manufacture, possession or operation of the Equipment, including, without limitation, injury
to persons or property resulting from the failure of, defective or faulty design, operation, condition, suitability or use of
the Equipment. All warranty or other similar claims with respect to the Equipment shall be made by Medical Center
solely and exclusively against Elekta and any other manufacturers or suppliers, but shall in no event be asserted against
GKF. In this regard and with prior written approval of GKF, Medical Center may, in GKF’s name, but at Medical
Center’s sole cost and expense, enforce all warranties, agreements or representations, if any, which may have been made
by Elekta or manufacturers, suppliers or other third parties regarding the Equipment to GKF or Medical Center. GKF shall not
be responsible for the delivery or operation of the Equipment or for any delay or inadequacy of either or both of the
foregoing.

 

    - 13 - 

     

    

 

18.         Termination
for Economic Justification. If, following the initial twenty four (24) months after the First Procedure Date and following each
subsequent 12 month period thereafter during the Term, based upon the utilization of the Equipment and other factors considered
relevant by GKF in the exercise of its reasonable discretion, within a reasonable period of time after GKF’s written
request, Medical Center does not provide GKF with a reasonable economic justification to continue this Agreement and the utilization
of the Equipment at the Medical Center, then and in that event, GKF shall have the option to terminate this Agreement by giving
a written notice thereof to Medical Center not less than one hundred eighty (180) days prior to the effective date of the termination
designated in GKF’s written notice. Without limiting the generality of the foregoing, for purposes of this Section, “reasonable
economic justification to continue this Agreement” shall not be deemed to exist (and GKF shall have the option to terminate
this Agreement) if, during the twelve (12) month period immediately preceding the issuance of GKF’s written notice of termination,
the “Net Cash Flow” is negative. As used herein, “Net Cash Flow” shall mean, for the applicable period,
(a) the aggregate Purchased Services Payments actually received by GKF during such period, minus (b) the sum of the aggregate (i)
debt service on the Equipment, (ii) maintenance expenses, (iii) marketing support, and (iv) Equipment-related personal property
taxes and insurance during such period.

 

19.         Options
to Extend Agreement. As of the end of the Term, Medical Center shall have the option either to:

 

    - 14 - 

     

    

 

19.1         Extend
the Term of this Agreement for a specified period of time and upon such other terms and conditions as may be agreed upon by GKF
and Medical Center;

 

19.2         Terminate
this Agreement as of the expiration of the Term. Upon the expiration of the Term and within a reasonable time thereafter, GKF,
at its cost and expense, may enter upon the Site under Medical Center supervision and remove the Equipment.

 

19.3         Medical
Center may elect to purchase the Equipment from GKF for the fair market value amount (as mutually agreed upon by the parties) as
of the expiration date of Term, payable in cash (or other immediately available federal funds), at the end of the Term.

 

Medical Center shall exercise one (1) of the
three (3) options referred to above by giving an irrevocable written notice thereof to GKF at least one (1) year prior to the expiration
of the initial Term. Any such notice shall be sufficient if it states in substance that Medical Center elects to exercise its option
and states which of the three (3) options referred to above Medical Center is exercising. If Medical Center fails to exercise the
option granted herein at least one (1) year prior to the expiration of the initial Term, the option shall lapse and this Agreement
shall expire as of the end of the initial Term. Further, if Medical Center exercises the option specified in Section 19.1 above
and the parties are unable to mutually agree upon the length of the extension of the Term or any other terms or conditions applicable
to such extension prior to the expiration of the Term, this Agreement shall expire as of the end of the initial Term.

 

		20.	Events of Default and Remedies.

(30) days to cure, Medical Center commences to cure the default during the initial thirty (30) day period and Medical Center diligently
completes the cure within sixty (60) days following the end of the thirty (30) day period, such default shall not constitute a
Medical Center Event of Default; provided that the foregoing cure periods shall not apply to a Medical Center Event of Default

days after written notice thereof is given by Medical Center or its assignee to GKF; however, if GKF cures the default within the
applicable fifteen (15) day period, such default shall not constitute a GKF Event of Default.

fails to observe or perform any of its covenants, duties or obligations arising under this Agreement and such failure continues
for a period of thirty (30) days after written notice thereof by Medical Center to GKF; however, if GKF cures the default within
the applicable thirty (30) day period or if the default reasonably requires more than thirty (30) days to cure, GKF commences to
cure the default during the initial thirty (30) day period and GKF diligently completes the cure within sixty (60) days following
the end of the thirty (30) day period, such default shall not constitute a GKF Event of Default; provided that the foregoing cure
periods shall not apply to a GKF Event of Default under Subsections 20.2.1, 20.2.2, or 20.2.3.

or all of the following:

 

20.3.1           By
written notice to GKF, Medical Center may at its option immediately terminate this Agreement as to the Equipment, wherever situated,
but only upon the occurrence of a GKF Event of Default under Subsections 20.2.1 20.2.2 and/or 20.2.3. As a result of such termination,
Medical Center may, at its option and upon written notice to GKF, demand that GKF immediately enter upon the Site and remove the
Equipment at GKF’s sole cost and expense. For the avoidance of doubt, Medical Center shall not have the right to terminate
this Agreement by reason of a GKF Event of Default, other than due to the occurrence of a GKF Event of Default under Subsections
20.2.1 20.2.2 and/or 20.2.3.

 

20.3.2           By
written notice to Medical Center, GKF may at its option immediately terminate this Agreement as to the Equipment, wherever situated,
but only upon the occurrence of any of the Medical Center Events of Default as set forth in Subsections 20.1.1, 20.1.2, 20.1.6
and/or noncompliance with Sections 10.1 and/or 10.5 above (which noncompliance has not been cured within the periods set forth
in Section 20.1.3 above) (collectively, the “Termination Defaults”). For the avoidance of doubt, but without limiting
GKF’s rights under Section 18 above (Termination for Economic Justification), GKF shall not have the right to terminate this
Agreement by reason of a Medical Center Event of Default, other than due to the occurrence of any Termination Default. As a result
of such termination pursuant to any Termination Default, GKF may (a) provide reasonable notice to Medical Center of its intention
to remove the Equipment, and upon such date as provided by notice, GKF may then enter upon the Site and remove the Equipment in
a manner and at a time that causes least amount of disruption to patient care, or, at Medical Center’s election, Medical
Center shall remove and return the Equipment to GKF, but in either event at Medical Center’s sole cost and expense; and (b)
recover from Medical Center as liquidated damages for the loss of the bargain represented by this Agreement and not as a penalty
an amount equal to the present value of the unpaid estimated future Purchased Services Payments to be made by Medical Center to
GKF through the end of the Term discounted at the rate of nine percent (9%), which liquidated damages shall become immediately
due and payable. The unpaid estimated future Purchased Services Payments shall be based on the prior twelve (12) months Purchased
Services Payments made by Medical Center to GKF hereunder with an annual four (4%) percent increase thereof through the end of
the Term. Medical Center and GKF acknowledge that the liquidated damages formula set forth in this Section constitutes a reasonable
method to calculate GKF’s damages resulting from any Termination Default and under the circumstances existing as of the date
of this Agreement.

 

    - 18 - 

     

    

 

20.3.3           With
respect to all other Medical Center Events of Default, GKF may:

 

A.           Sell,
dispose of, hold, use or lease the Equipment, as GKF in its sole and absolute discretion may determine (and GKF shall not be obligated
to give preference to the sale, lease or other disposition of the Equipment over the sale, lease or other disposition of similar
Equipment owned or leased by GKF).

 

B.           Exercise
any other right or remedy which may be available to GKF under the Uniform Commercial Code or any other applicable law or proceed
by appropriate court action, without affecting GKF’s title or right to possession of the Equipment, to enforce the terms
hereof or to recover damages for the breach hereof or to cancel this Agreement as to the Equipment.

 

20.3.3           Upon
termination of this Agreement or the exercise of any other rights or remedies under this Agreement or available under applicable
law following a Medical Center Event of Default, Medical Center shall, without further request or demand, pay to GKF all Purchased
Services Payments and other sums owing under this Agreement. In the event that Medical Center shall pay the liquidated damages
referred to in Section 20.3.2 above to GKF, GKF shall pay to Medical Center promptly after receipt thereof all rentals or proceeds
received from the reletting or sale of the Equipment during the balance of the initial Term (after deduction of all costs and expenses,
including reasonable attorneys fees and costs, incurred by GKF as a result of the Event of Default), said amount never to exceed
the amount of the liquidated damages paid by Medical Center. However, Medical Center acknowledges that GKF shall have no obligation
to sell the Equipment. Medical Center shall in any event remain fully liable for all damages as may be provided by law and for
all costs and expenses incurred by GKF on account of such default, including but not limited to, all court costs and reasonable
attorneys’ fees.

 

20.3.4           Subject
to Section 17 above, each party shall in any event remain fully liable to the other non-defaulting party for all damages as may
be provided by law and for all costs and expenses incurred by the non-defaulting party on account of such default, including but
not limited to, all court costs and reasonable attorneys’ fees.

 

20.3.5           Subject
to Sections 20.3.1 and 20.3.2 above (regarding limitations on the right to terminate this Agreement), the rights and remedies afforded
a non-defaulting party under this Agreement shall be deemed cumulative and not exclusive, and shall be in addition to any other
rights or remedies available to the non-defaulting party provided by law or in equity.

		21.	Insurance.

 

21.1         During
the Term, GKF shall, at its cost and expense, purchase and maintain in effect an all risk property and casualty insurance policy
covering the Equipment. The all risk property and casualty insurance policy shall be for an amount not less than the replacement
cost of the Equipment. Medical Center shall be named as an additional insured party on the all risk property and casualty insurance
policy to the extent of its interest in the Equipment arising under this Agreement. The all risk property and casualty insurance
policy maintained by GKF shall be evidenced by a certificate of insurance or other reasonable documentation which shall be delivered
by GKF to Medical Center upon request following the commencement of this Agreement and as of each annual renewal of such policy
during the Term.

 

21.2         During
the Term, Medical Center shall, at its cost and expense, self-insure (subject to GKF’s reasonable approval pursuant to Section
21.5 below) or purchase, and maintain in effect general liability and professional liability insurance coverage/policies covering
the Site (together with all premises where the Site is located) and the use or operation of the Equipment by Medical Center or
its officers, directors, agents, employees, contractors or physicians. The general liability and professional liability insurance
policies shall provide coverage in amounts not less than One Million Dollars ($1,000,000.00) per occurrence and Five Million Dollars
($5,000,000.00) annual aggregate. GKF shall be named as additional insured party on the general liability and professional liability
insurance coverage/policies to be maintained hereunder by Medical Center. The coverage/policies to be maintained by Medical Center
hereunder shall be evidenced by a certificate of insurance or other reasonable documentation which shall be delivered by Medical
Center upon request to GKF no later than the First Procedure Date and as of each annual renewal of such policies during
the Term. Notwithstanding anything to the contrary herein, subject to Section 6.4 above and any contributory fault by Medical Center
and/or its employees, contractors, affiliates, agents or representatives, neither Medical Center nor its insurer shall be liable
to GKF for any injury or loss to persons or property caused by the failure or malfunction of the Equipment itself or the improper
installation of the Equipment or the improper installation and/or cleaning of hydraulic hoses in connection with the installation
of new Equipment; but, as to improper installation of the Equipment, such liability shall be that of and remain with GKF; and as
to the Equipment itself, the liability shall be that of and remain with the manufacturer under the LGK Agreement.

 

21.3         During
the construction of the Site and prior to the First Procedure Date, Medical Center, at its cost and expense, shall self-insure
(subject to GKF’s reasonable approval pursuant to Section 21.5 below) or purchase, and maintain a general liability insurance
policy which conforms with the coverage amounts and other requirements described in Section 21.2 above and which names GKF as an
additional insured party. The policy to be maintained by Medical Center hereunder shall be evidenced by a certificate of insurance
or other reasonable documentation which shall be delivered by Medical Center to GKF prior to the commencement of any construction
at the Site.

 

    - 20 - 

     

    

 

21.4         During
the Term, Medical Center and GKF shall purchase and maintain all workers compensation insurance to the maximum extent required
by applicable law.

 

21.5         If
Medical Center elects to self-insure, within twenty (20) days following the date hereof, Medical Center shall submit to GKF, in
writing, information on Medical Center’s proposed self-insurance program and obtain GKF’s approval of the program,
which approval shall not be unreasonably withheld. If GKF does not disapprove of such self-insurance program within thirty (30)
days following its receipt of such information, GKF shall be deemed to have given its approval.

 

		22.	Indemnification.

 

22.1         Medical
Center shall be liable for and shall indemnify, defend, protect and hold GKF and its members, managers, officers, employees, agents
and contractors (collectively “GKF”) harmless from and against all losses, claims, damages, liabilities, assessments,
deficiencies, actions, proceedings, orders, judgments, liens, costs and other expenses (including reasonable attorney’s fees)
of any nature or kind whatsoever asserted against or incurred by GKF (collectively “Damages”) which in any manner arise
out of or relate to (a) the failure by Medical Center to fully perform, observe or satisfy its covenants, duties or obligations
contained in this Agreement or in the LGK Agreement; (b) negligent, intentional or wrongful acts or omissions by Medical Center
or any of its officers, directors, agents, contractors (or their subcontractors), or employees in connection with the use and operation
of the Equipment during the Term; (c) defects arising out of materials or parts provided, modified or designed by Medical Center
for or with respect to the Site; (d) the maintenance of the Site during the Term by Medical Center; (e) Damages to the Equipment
caused by the negligent or wrongful acts or omissions of Medical Center, its agents, officers, employees or contractors (if the
Equipment is destroyed or rendered unusable, subject to Section 22.7 below, this indemnity shall extend up to (but not exceed)
the full replacement value of the Equipment at the time of its destruction less salvage value, if any); (f) the events or occurrences
described in Article 7.3 of the LGK Agreement to the same extent that Medical Center agrees to indemnify Elekta thereunder (other
than with respect to the failure of the Site to comply with the Site Planning Criteria or defective maintenance of the Equipment
under the Service Agreement); and (g) any other matters for which Medical Center has specifically agreed to indemnify GKF
pursuant to this Agreement.

 

    - 21 - 

     

    

 

22.2         GKF
shall be liable for and shall indemnify, defend, protect and hold Medical Center and its directors, members, managers, officers,
employees, agents and contractors (collectively “Medical Center”) harmless from and against all losses, claims, damages,
liabilities, assessments, deficiencies, actions, proceedings, orders, judgments, liens, costs and other expenses (including reasonable
attorney’s fees) of any nature or kind whatsoever asserted against or incurred by Medical Center (collectively “Damages”)
which in any manner arise out of or relate to (a) the failure by GKF to fully perform, observe or satisfy its covenants, duties
or obligations contained in this Agreement; (b) negligent, intentional or wrongful acts or omissions by GKF or any of its officers,
directors, agents, contractors (or their subcontractors), or employees in connection with the installation or removal of the Equipment,
(c) the failure by GKF to maintain the Equipment as provided in this Agreement; and (d) any other matters for which GKF has specifically
agreed to indemnify Medical Center pursuant to this Agreement.

 

22.3         Upon
the occurrence of an event for which GKF or Medical Center is entitled to indemnification under this Agreement (“Indemnitee”),
such party shall give written notice thereof to the other party setting forth the type and amount of Damages. If the indemnity
relates to a Third Party Claim (as defined in Section 22.4 below), the matter shall be subject to Section 22.4 below. If the indemnity
relates to any Damages other than a Third Party Claim, not more than thirty (30) days after written notice is given, the indemnifying
party shall acknowledge its obligation in writing to the Indemnitee to indemnify hereunder and pay the Damages in full to the Indemnitee.

 

22.4         GKF
or Medical Center, as Indemnitee, shall give written notice to the other party as Indemnitor as soon as reasonably possible after
the Indemnitee has knowledge of any third party claim or legal proceedings (“Third Party Claim”) for which the Indemnitee
is entitled to indemnification under this Section 22. Indemnitor shall (a) immediately assume, at its sole cost and expense, the
defense of the Third Party Claim with legal counsel approved by the Indemnitee (which approval will not be unreasonably withheld,
delayed or conditioned), and (b) as soon as reasonably possible after Indemnitee’s written notice is given to the Indemnitor,
acknowledge in writing to Indemnitee its obligation to indemnify Indemnitee in accordance with the terms of this Agreement. If
either party as the Indemnitor fails to assume the defense of a Third Party Claim or fails to timely acknowledge in writing its
obligation to indemnify the Indemnitee, then, the Indemnitee may assume the defense of the Third Party Claim in the manner described
in Section 22.5 below. Each party shall cooperate with the other in the defense of any Third Party Claim. Any settlement or compromise
of a Third Party Claim to which either party is a party shall be subject to the express written approval of the other party, which
approval shall not be unreasonably withheld, delayed or conditioned as long as an unconditional term of the settlement or compromise
is the full and absolute release of the Indemnitee from all Damages arising out of the Third Party Claim. Either party as Indemnitee,
at its own cost and expense, may participate on its own behalf with legal counsel of its own selection in the defense of any Third
Party Claim which may have a material impact on it.

 

    - 22 - 

     

    

 

22.5         If
either party having the obligation as Indemnitor fails to promptly assume the defense of any Third Party Claim, the Indemnitee
may assume the defense of the Third Party Claim with legal counsel selected by the Indemnitee, all at the Indemnitor’s cost
and expense. The defense of an action by an Indemnitee under this Section 22.5 shall not impair, limit or otherwise restrict Indemnitor’s
indemnification obligations arising under this Section 22 or Indemnitee’s right to enforce such obligations.

 

22.6         The
indemnity obligations under this Section 22 shall expire on the expiration of the applicable statute of limitations relating to
the underlying claim that is the subject of the indemnification claim. Any indemnification obligation shall be in proportion to
the amount of responsibility found attributable to the Indemnitor.

 

22.7         The
indemnification obligations set forth in this Agreement are intended to supplement, and not supersede, supplant or replace, any
coverage for Damages which may be available under any insurance policies that may be maintained by GKF or Medical Center. In the
event any Damages may be covered by insurance policies, the parties shall exercise good faith and use their best efforts to obtain
the benefits of and apply the available insurance coverage to the Damages subject to indemnification under this Agreement. In the
event that an insurer provides coverage under an insurance policy on the basis of a “reservation of rights”, the indemnification
obligations under this Agreement shall apply to all Damages which are finally determined as not being covered under the insurance
policy.

 

		23.	Miscellaneous.

 

23.1         Binding
Effect. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns. Medical Center shall not assign this Agreement or any of its rights hereunder or sublease the Equipment without the prior
written consent of GKF, which consent shall not be unreasonably withheld; provided, however that the Medical Center may assign
this Agreement without prior written consent of GKF to an entity controlled by, controlling, or under common control with the Medical
Center and which entity is the holder of the general acute care hospital license for the facility at which the Equipment
is located, and provided further, that such entity shall have credit rating and financial position equivalent to
or higher than that of Medical Center as reasonably determined by GKF. Unless otherwise agreed to in writing by GKF,
an assignment or sublease shall not relieve Medical Center of any liability for performance of this Agreement during the remainder
of the Term. Any purported assignment or sublease made without GKF’s prior written consent shall be null, void and of no
force or effect. 

 

    - 23 - 

     

    

 

23.2         Agreement
to Perform Necessary Acts. Each party agrees to perform any further acts and execute and deliver any further documents which may
be reasonably necessary or otherwise reasonably required to carry out the provisions of this Agreement.

 

23.3         Validity.
If for any reason any clause or provision of this Agreement, or the application of any such clause or provision in a particular
context or to a particular situation, circumstance or person, should be held unenforceable, invalid or in violation of law by any
court or other tribunal of competent jurisdiction, then the application of such clause or provision in contexts or to situations,
circumstances or persons other than that in or to which it is held unenforceable, invalid or in violation of law shall not be affected
thereby, and the remaining clauses and provisions hereof shall nevertheless remain in full force and effect.

 

23.4         Attorney’s
Fees and Costs. In the event of any action, arbitration or other proceedings between or among the parties hereto with respect to
this Agreement, the non-prevailing party or parties to such action, arbitration or proceedings shall pay to the prevailing party
or parties all costs and expenses, including reasonable attorneys’ fees, incurred in the defense or prosecution thereof by
the prevailing party or parties. The party which is a “prevailing party” shall be determined by the arbitrator(s) or
judge(s) hearing the matter and shall be the party who is entitled to recover his, her or its costs of suit, whether or not the
matter proceeds to a final judgment, decree or determination. A party not entitled to recover his, her or its costs of suit shall
not recover attorneys’ fees. If a prevailing party or parties shall recover a decision, decree or judgment in any action,
arbitration or proceeding, the costs and expenses awarded to such party may be included in and as part of such decision, decree
or judgment.

 

23.5         Entire
Agreement; Amendment. This Agreement together with the Exhibits attached hereto constitutes the full and complete agreement and
understanding between the parties hereto concerning the subject matter hereof and shall supersede any and all prior written and
oral agreements with regard to such subject matter. This Agreement may be modified or amended only by a written instrument executed
by all of the parties hereto.

 

23.6         Number
and Gender. Words in the singular shall include the plural, and words in a particular gender shall include either or both additional
genders, when the context in which such words are used indicates that such is the intent.

 

23.7         Effect
of Headings. The titles or headings of the various paragraphs hereof are intended solely for convenience or reference and are not
intended and shall not be deemed to modify, explain or place any construction upon any of the provisions of this Agreement.

 

23.8         Counterparts.
This Agreement may be executed in one or more counterparts by the parties hereto. All counterparts shall be construed together
and shall constitute one agreement.

 

    - 24 - 

     

    

 

23.9         Governing
Law. This Agreement shall be interpreted and enforced in accordance with the internal laws, and not the law of conflicts, of the
State of Ohio applicable to agreements made and to be performed in that State by a court of competent jurisdiction sitting in Montgomery
County, Ohio. The parties waive, to the fullest extent they may effectively do so, the defense of an inconvenient or inappropriate
forum to the maintenance of any action or proceeding, and waive any defense based on lack of personal jurisdiction of any such
party.

 

23.10         Exhibits.
All exhibits attached hereto and referred to in this Agreement are hereby incorporated by reference herein as though fully set
forth at length.

 

23.11         Ambiguities.

made by any other party hereto or by any of its agents, employees, representatives or attorneys; (b) that this Agreement is not
being entered into on the basis of, or in reliance on, any promise or representation, expressed or implied, other than such as

No failure or delay by a party to insist upon the strict performance of any term, condition, covenant or agreement of this Agreement,
or to exercise any right, power or remedy hereunder or under law or consequent upon a breach hereof or thereof shall constitute
a waiver of any such term, condition, covenant, agreement, right, power or remedy or of any such breach or preclude such party
from exercising any such right, power or remedy at any later time or times.

 

23.14         Notices.
All notices, requests, demands or other communications required or permitted to be given under this Agreement shall be in writing

		23.15	Special Provisions Respecting Medicare and Medicaid Patients

 

23.15.1         Medical
Center and GKF shall generate such records and make such disclosures as may be required, from time to time, by the Medicare, Medicaid,
TriCare, HCAP and other third party payment programs with respect to this Agreement in order to meet all requirements for participation
and payment associated with such programs, including but not limited to the matters covered by Section 1861(v)(1)(I) of the Social
Security Act.

 

23.15.2         For
the purpose of compliance with Section 1861(v)(1)(I) of the Social Security Act, as amended, and any regulations promulgated pursuant
thereto, both parties agree to comply with the following statutory requirements (a) Until the expiration of four (4) years after
the termination of this Agreement, both parties shall make available, upon written request to the Secretary of Health and Human
Services or, upon request, to the Comptroller General of the United States, or any of their duly authorized representatives, the
contract, and books, documents and records of such party that are necessary to certify the nature and extent of such costs, and
(b) if either party carries out any of the duties of the contract through a subcontract with a value or cost of $10,000 or more
over a twelve month period, with a related organization, such subcontract shall contain a clause to the effect that until the expiration
of four (4) years after the furnishing of such services pursuant to such subcontract, the related organization shall make available,
upon written request to the Secretary, or upon request to the Comptroller General, or any of their duly authorized representatives
the subcontract, and books, documents and records of such organization that are necessary to verify the nature and extent of such
costs.

 

    - 26 - 

     

    

 

23.16         Force
Majeure. Failure to perform by either party will be excused in the event of any delay or inability to perform its duties under
this Agreement directly or indirectly caused by conditions beyond its reasonable control, including, without limitation, fires,
floods, earthquakes, snow, ice, disasters, acts of God, accidents, riots, wars, operation of law, strikes, governmental action
or regulations, shortages of labor, fuel, power, materials, manufacturer delays or transportation problems. Notwithstanding the
foregoing, all parties shall make good faith efforts to perform under this Agreement in the event of any such circumstance. Further,
once such an event is resolved, the parties shall again perform their respective obligations under this Agreement. Notwithstanding
the foregoing, and for the avoidance of doubt, no reductions or other changes to reimbursement amounts and/or payment methodology(ies)
pertaining to any third party payors or governmental programs, including, without limitation, Medicare, Medicaid, any other federal
or state programs, and/or any commercial payors, shall be deemed to constitute a force majeure event under this Section, and shall
not excuse or delay Medical Center’s obligations under this Agreement or provide Medical Center with the right to terminate
this Agreement. However, in the event that two independent legal counsel specializing in healthcare law (collectively, the “Independent
Legal Counsel”), who are resident in states other than Ohio and California issue separate written legal opinions addressed
to both of the parties stating that any federal, state or local law or regulation currently existing or hereinafter enacted, or
any final or non-appealable construction or interpretation of such law or regulation or enforcement of such laws or regulations
which hereinafter occurs, makes performance of this Agreement impossible, illegal or disqualifies a party from providing services
to Medicare or Medicaid patients, the parties mutually agree to use their best efforts to enter into a modification of this Agreement
to make substantial performance of this Agreement possible, legal or to qualify a party to provide its services to Medicare or
Medicaid patients; but if (a) the parties are unable to reach agreement upon appropriate modification following thirty (30) days
of good faith negotiations, or sooner if required by law, and (b) the Independent Legal Counsel each determine in writing that
any such modification would be impossible, illegal or would disqualify a party from providing services to Medicare or Medicaid
patients, then, this event shall be deemed to constitute a force majeure event under this Section, and shall provide either party
with the right to terminate this Agreement without further obligations except for those accruing to the date of termination and
those obligations surviving the date of termination as provided hereunder. Each party shall select one of the two Independent Legal
Counsel to render the aforementioned opinions. All costs and expenses of the Independent Legal Counsel will be borne by the party
initiating the request unless the determination is made by the Independent Legal Counsel as described above that the performance
of this Agreement is impossible, illegal or disqualifies a party from providing services to Medicare or Medicaid patients, in which
event, such costs and expenses shall be shared equally between the parties. In the event that the two Independent Legal Counsel
render conflicting opinions, either the parties hereto shall decide upon a third attorney who meets the above qualifications or
shall instruct the Independent Legal Counsel to select a third attorney specializing in healthcare law to review and render an
opinion, which opinion by such third attorney shall be binding on both parties. Under the circumstance of having to select a third
attorney, the costs of the Independent Legal Counsel shall be borne by the party selecting such counsel and the costs of the third
attorney shall be borne equally by the parties.

 

    - 27 - 

     

    

 

23.17         Independent
Contractor. It is mutually understood and agreed that nothing in this Agreement is intended nor shall be construed to create between
GKF and Medical Center, with respect to their relationship hereunder, an employer/employee relationship, a partnership or joint
venture relationship, or a landlord/tenant relationship.

 

23.18         Supplier
and Owner of Equipment. The parties hereto agree that, notwithstanding anything to the contrary set forth in this Agreement, this
Agreement is and shall be treated and interpreted as a "finance lease," as such term is defined in Article 2A of the
Uniform Commercial Code and Chapter 1310 of the Ohio Revised Code, that GKF shall be treated as a finance lessor who is entitled
to the benefits and releases from liability accorded to a finance lessor under Article 2A of the Uniform Commercial Code and Chapter
1310 of the Ohio Revised Code. In furtherance of the foregoing, Medical Center acknowledges that, before signing this Agreement,
GKF has informed Medical Center in writing (a) that Elekta is the entity supplying the Equipment to GKF, (b) that Medical Center
is entitled (under Section 2A of the Uniform Commercial Code and Chapter 1310 of the Ohio Revised Code) to the promises and warranties,
including those of any third party, provided to GKF by Elekta which is the entity supplying the goods in connection with or as
part of the contract by which GKF acquired the Equipment or the right to possession and use of the Equipment, and (c) that Medical
Center may communicate with Elekta and receive an accurate and complete statement of those promises and warranties, including any
disclaimers and limitations of them or of remedies. Medical Center also acknowledges that Medical Center has selected Elekta to
supply the Equipment and has directed GKF to acquire the Equipment or the right to possession and use of the Equipment from Elekta.

 

23.19         Termination
of Model B Lease. The existing Lease Agreement For a Gamma Knife Unit dated June 1, 1998 (as amended, the “Prior Agreement”),
between GKF and Medical Center shall continue in full force and effect until the Model B is deinstalled by GKF pursuant to Section
6.5 above, at which time the Prior Agreement shall terminate, except for any payments or other obligations which remain due and
owing as of such termination, and/or any provisions that are intended to survive such termination.

 

    - 28 - 

     

    

 

23.20         Business
Associate. This Agreement shall be deemed to incorporate all terms that HIPAA
requires to be included in a business associate contract pertaining to such information, as applicable; provided that any breach
of any of the terms of such business associate contract shall not give Medical Center the right to terminate this Agreement given
that termination of this Agreement would not be feasible, and that such breach shall instead be reported to the Secretary of the

Exhibit 2

 

LGK AGREEMENT

 

The following provisions shall be added to the Elekta Instruments,
Inc. (“Elekta”) LGK End User Agreement (“LGK Agreement”), and are hereby incorporated into such LGK Agreement
by this reference, and GKF agrees that its agreement with Elekta shall include that such provisions shall be included in LGK’s
Agreement with the Medical Center, subject to acceptance by Elekta:

 

Business
Associate.  Elekta and its employees, agents and/or contractors will have access to patient protected health
information maintained by the Medical Center in order to perform certain service and support functions, and, therefore, in
compliance with the Health Insurance Portability and Accountability Act, Elekta agrees to execute the Business Associate
Agreement tendered to it by the Medical Center.

 

Patent and Copyright Indemnity.
Elekta will defend or settle, at its own expense, any claim or suit against Medical Center alleging that any Elekta Equipment or
parts furnished under the LGK Agreement with Medical Center infringe any United States patent or copyright. Elekta will also pay
all damages and costs that by final judgment may be assessed against Medical Center due to such infringement. If the Equipment
provided under Medical Center’s Agreement with GKF becomes, or in Elekta’s opinion is likely to become the subject
of an infringement suit, Elekta will, at its option: (1) work with GKF to procure for Medical Center the right to continue using
the Equipment; (2) cooperate with GKF to replace or modify the Equipment to provide Medical Center with a non-infringing product
that is functionally equivalent in all material respects; or (3) work with GKF to remove the Equipment from Medical Center’s
Site at no cost and expense to Medical Center and to terminate both the GKF Agreement and the LKG Agreement with Medical Center
related to the Equipment without further obligation of Medical Center to either party.

 

Delivery and Defective Equipment
Indemnity.  Elekta agrees to fully indemnify, defend and hold harmless the
Medical Center and its affiliates, and their respective directors, officers, employees and agents from and against any and all
claims, losses, expenses, liabilities, injuries to persons or property, judgments, settlements, suits, damages or costs (including
reasonable attorneys’ fees and expenses) arising out of, or in any way related to, or caused by defective Equipment provided
to Medical Center under its agreement with Electa or GKF, or materials or parts furnished for such Equipment during the Term of
any such Agreement. Elekta additionally agrees to solely bear the risk of loss concerning the Equipment during delivery to the
Medical Center and agrees to fully indemnify, defend and hold harmless the Medical Center from and against any and all loss or
damage to Equipment during or prior to delivery to Medical Center Site.

Special Activity
Certificates. Elekta agrees that any Gamma Knife experienced neurosurgeon and/or radiation physicist or other physician
furnished by Elekta to provide on-site application training shall obtain a Special Activity Certificate from the Ohio State
Medical Board and shall be credentialed by the Medical Center’s medical staff prior to the provision of such on-site
training.

 

Response Time for Technical
Support. Elekta agrees that its response time for any requested on-site or remote technical support shall be provided within the
time frames indicated in a separate document provided to the Medical Center entitled “Leksell Gamma Knife Perfexion Advanced
Service and Support Service Description”.

 Collections Payable To GKF For
 Each Procedure	 
	1-7	 	 	1-150	 	 	39.5	%*
	1-7	 	 	151+	 	 	29.5	%

 

Notwithstanding anything to the contrary set
forth herein, for purposes of determining the Purchased Services Payments, the number of annual Procedures performed shall be reset
to zero (0) at the commencement of each anniversary of the First Procedure Date.

 

For Procedure count purposes, any patient treatment
provided on a fractionated basis shall count as one (1) Procedure. Charity cases shall not be included in the annual Procedures
performed count.

 

* Commencing upon the utilization of any portion
or all of the Equipment Modification Allowance stipulated in Section 13.1 above, and continuing through the remaining Term of the
Agreement, the Purchased Services Payments for each of the first one hundred fifty (150) Procedures performed during any annual
period during the Term shall be increased from thirty-nine and one-half percent (39.5%) to forty-one and two-tenths percent (41.2%).
The Purchased Services Payments for each additional Procedure in excess of 150 Procedures performed during any such annual period
shall remain unchanged as provided above.

 

Charity Cases

 

As a means to support Medical Center’s
mission of providing charity care for persons who require Gamma Knife procedures who are not covered by Medicare, Medicaid, TriCare,
Ohio’s Hospital Care Assurance Program, or private insurance programs (whether indemnity, preferred provider, health maintenance
organization, etc.) and who do not have the means to pay for such procedures based on Medical Centers adopted standards of indigency,
GKF agrees that Medical Center may perform Procedures on a charity or unreimbursed basis so long as no such charity or unreimbursed
Procedures are counted towards the number of annual paid Procedures performed for purposes of determining the Purchased Services
Payments due hereunder. Medical Center shall be solely responsible (and GKF shall not in any manner be or become responsible) for
determining whether any person meets the standards of indigency. Medical Center shall provide reasonable written documentation
evidencing satisfaction of the conditions set forth herein to GKF at or prior to the expected time of treatment.
