                     (the “Participant”). 
 WHEREAS, the Company has adopted and maintains the Harrah’s Entertainment, Inc. Management Equity Incentive Plan (the “Plan”) to promote the interests of the Company and its Affiliates and
Stockholders by providing the Company’s key employees and others with an appropriate incentive to encourage them to continue in the employ of and provide services for the Company or its Affiliates and to improve the growth and profitability of
the Company; 
 WHEREAS, the Plan provides for the Grant to Participants of Options to purchase Shares. 
 NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter set forth, the parties hereto hereby agree as follows: 

1. Grant of Options. Pursuant to, and subject to, the terms and conditions set forth herein and in the Plan, the Company hereby grants to the
Participant a Time-Based Option, a 2X Performance Option and a 3X Performance Option as set forth on the signature page hereto. 
 2.
Grant Date. The Grant Date of the Option hereby granted is July 1, 2008. 
 3. Incorporation of Plan. All terms,
conditions and restrictions of the Plan are incorporated herein and made part hereof as if stated herein. If there is any conflict between the terms and conditions of the Plan and this Agreement, the terms and conditions of this Agreement, as
interpreted by the Committee, shall govern. All capitalized terms used and not defined herein shall have the meaning given to such terms in the Plan. 
 4. Exercise Price. The exercise price of each Share underlying the Option hereby granted is set forth on the signature page hereto. 
 5. Special Provisions for Forfeiture. Notwithstanding the provisions of clauses (c), (d) or (e) of the first sentence of Section 4.4 of the Plan, in the event that the Participant’s
Employment terminates due to the reasons set forth in clauses (c), (d) or (e) of the first sentence of Section 4.4 of the Plan, any vested but unexercised portion of the Time-Based Option shall remain exercisable until the earlier of
the date (i) on which the Participant receives a cash payment in exchange for the surrender of the Time-Based Option pursuant to a Change in Control, (ii) that is sixty (60) days after the Shares underlying the Time-Based Option are

five anniversaries of April 7, 2008, until 100% of such Time-Based Option is fully vested and exercisable, subject in all cases to the Participant’s continued Employment through the applicable Vesting Date. 

 7. Construction of Agreement. Any provision of this Agreement (or portion thereof) which is deemed
invalid, illegal or unenforceable in any jurisdiction shall, as to that jurisdiction and subject to this section, be ineffective to the extent of such invalidity, illegality or unenforceability, without affecting in any way the remaining provisions
thereof in such jurisdiction or rendering that or any other provisions of this Agreement invalid, illegal, or unenforceable in any other jurisdiction. If any covenant should be deemed invalid, illegal or unenforceable because its scope is considered
excessive, such covenant shall be modified so that the scope of the covenant is reduced only to the minimum extent necessary to render the modified covenant valid, legal and enforceable. No waiver of any provision or violation of this Agreement by
the Company shall be implied by the Company’s forbearance or failure to take action. This Agreement is intended to comply with Section 409A of the Code and any guidance issued thereunder and shall be interpreted, operated and administered
by the Committee accordingly. 
 8. Delays or Omissions. No delay or omission to exercise any right, power or remedy accruing to any
party hereto upon any breach or default of any party under this Agreement, shall impair any such right, power or remedy of such party nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any
similar breach or default thereafter occurring nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or
character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party or any provisions or conditions of this Agreement, shall be in writing and shall be effective only to the extent specifically
set forth in such writing. 
 9. Limitation on Transfer. The Option shall be exercisable only by the Participant or the
Participant’s Permitted Transferee(s), as determined in accordance with the terms of the Plan (including without limitation the requirement that the Participant obtain the prior written approval by the Committee of any proposed Transfer to a
Permitted Transferee during the lifetime of the Participant). Each Permitted Transferee shall be subject to all the restrictions, obligations, and responsibilities as apply to the Participant under the Plan and this Stock Option Grant Agreement and
shall be entitled to all the rights of the Participant under the Plan, provided that in respect of any Permitted Transferee which is a trust or custodianship, the Option shall become exercisable and/or expire based on the Employment and termination
of Employment of the Participant. All Shares obtained pursuant to the Option granted herein shall not be transferred except as provided in the Plan and, where applicable, the Management Investor Rights Agreement. 
 10. No Special Employment Rights. Nothing contained in the Plan shall confer upon the Participant any right with respect to the continuation of
Employment or interfere in any way with the right of the Company or an Affiliate, subject to the terms of any separate Employment agreement to the contrary, at any time to terminate such Employment or to increase or decrease the compensation of the
Participant from the rate in existence at the time of the grant of the Option.

 11. Participant’s Undertaking and Consents. The Participant hereby agrees to take whatever
reasonable additional actions and execute whatever additional documents the Company may in its reasonable, good faith judgment deem necessary or advisable in order to carry out or effect one or more of the obligations or restrictions imposed on the
Participant pursuant to the express provisions of this Stock Option Grant Agreement and the Plan (it being understood that such additional actions and documents shall not in any way expand such obligations or restrictions). The Participant hereby
consents to the collection, retention, use, processing and transfer of the Participant’s personal data by the Company and any of its Affiliates, any administrator of the Plan, the Company’s registrars or brokers for the purposes of
implementing and operating the Plan.

subject matter hereof other than those expressly set forth herein and in the Plan. This Agreement, including without limitation the Plan, supersedes all prior agreements and understandings between the parties with respect to its subject matter,

 13.

 4Supplemental Indenture

 Exhibit 4.3 
 FIRST SUPPLEMENTAL INDENTURE 
 This First Supplemental Indenture (this “Supplemental
Indenture”), is dated as of the 30th day of June, 2006, among Florida Hospital Medicine Services, Inc. (the “Guaranteeing Subsidiary”), a subsidiary of Team Finance LLC, a Delaware limited liability company (the
“Issuer”), and The Bank of New York Trust Company, N.A., as trustee (the “Trustee”). 
 W I T N E S S E T H

 WHEREAS, each of the Issuer, Health Finance Corporation (the
“Co-Issuer” and, together with the Issuer, the “Issuers”) and the Guarantors (as defined in the Indenture referred to below) has heretofore executed and delivered to the Trustee an indenture (the
“Indenture”), dated as of November 23, 2005, providing for the issuance of an unlimited aggregate principal amount of 11 1/4% Senior Subordinated Notes due 2013 (the “Notes”); 
 WHEREAS, the Indenture
provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’
Obligations under the Notes and the Indenture on the terms and conditions set forth herein and under the Indenture (the “Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the parties mutually covenant and agree for the equal and ratable benefit of
the Holders of the Notes as follows: 
 (1) Capitalized Terms. Capitalized terms used herein without definition shall have the
meanings assigned to them in the Indenture. 
 (2) Agreement to Guarantee. The Guaranteeing Subsidiary hereby agrees as follows:

 (a) Along with all Guarantors named in the Indenture, to jointly and severally unconditionally guarantee to each Holder of
a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of the Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

 (i) the principal of and interest, premium and Additional Interest, if any, on the Notes will be promptly paid in full when
due, whether at maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder
will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in case of any
extension of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by
acceleration or otherwise. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors and the Guaranteeing Subsidiary shall be jointly and severally obligated to pay the same
immediately. This is a guarantee of payment and not a guarantee of collection. 
  

 1 

 (b) The obligations hereunder shall be unconditional, irrespective of the validity,
regularity or enforceability of the Notes or the Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the
Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. 
 (c) The following is hereby waived: diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or
bankruptcy of either of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever. 
 (d) This Guarantee shall not be discharged except by complete performance of the obligations contained in the Notes, the Indenture and this Supplemental Indenture, and the Guaranteeing Subsidiary accepts all
obligations of a Guarantor under the Indenture. 
 (e) If any Holder or the Trustee is required by any court or otherwise to
return to the Issuers, the Guarantors (including the Guaranteeing Subsidiary), or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid either to the Trustee or such
Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect. 
 (f) The
Guaranteeing Subsidiary shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. 
 (g) As between the Guaranteeing Subsidiary, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of
the obligations guaranteed hereby may be accelerated as provided in Article 6 of the Indenture for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the
obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 of the Indenture, such obligations (whether or not due and payable) shall forthwith become due and payable
by the Guaranteeing Subsidiary for the purpose of this Guarantee. 
 (h) The Guaranteeing Subsidiary shall have the right to
seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under this Guarantee. 
 (i) Pursuant to Section 11.02 of the Indenture, after giving effect to all other contingent and fixed liabilities that are relevant under any applicable Bankruptcy or fraudulent conveyance laws, and after giving
effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under Article 11 of the Indenture, this new Guarantee shall be
limited to the maximum amount permissible such that the obligations of such Guaranteeing Subsidiary under this Guarantee will not constitute a fraudulent transfer or conveyance. 
 (j) This Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against either of
the Issuers for liquidation, reorganization, should either of the Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of either of the Issuers’
assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to 

  

 2 

 
applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes and Guarantee, whether as a
“voidable preference”, “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded, reduced, restored or returned, the Note
shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 
 (k) In case any provision of this Guarantee shall be invalid, illegal or unenforceable, the validity, legality, and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby. 
 (l) This Guarantee shall be a general unsecured
senior subordinated obligation of such Guaranteeing Subsidiary, ranking pari passu with any other future Senior Indebtedness of the Guaranteeing Subsidiary, if any. 
 (m) Each payment to be made by the Guaranteeing Subsidiary in respect of this Guarantee shall be made without set-off, counterclaim,
reduction or diminution of any kind or nature. 
 (3) Execution and Delivery. The Guaranteeing Subsidiary agrees that the Guarantee
shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. 
 (4)
Merger, Consolidation or Sale of All or Substantially All Assets. 
 (a) Except as otherwise provided in Section 5.01(c) of the
Indenture, the Guaranteeing Subsidiary may not consolidate or merge with or into or wind up into (whether or not the Issuer or Guaranteeing Subsidiary is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of
all or substantially all of its properties or assets, in one or more related transactions, to any Person unless: 
 (i)(A) the Guaranteeing Subsidiary is the surviving corporation or the Person formed by or surviving any such consolidation or merger (if other than the Guaranteeing Subsidiary) or to which such sale, assignment, transfer, lease,
conveyance or other disposition will have been made is a corporation, limited liability company or limited partnership organized or existing under the laws of the jurisdiction of organization of the Guaranteeing Subsidiary, as the case may be, or
the laws of the United States, any state thereof, the District of Columbia, or any territory thereof (the Guaranteeing Subsidiary or such Person, as the case may be, being herein called the “Successor Person”); 
 (B) the Successor Person, if other than the Guaranteeing Subsidiary, expressly assumes all the obligations of the Guaranteeing Subsidiary
under the Indenture and the Guaranteeing Subsidiary’s related Guarantee pursuant to supplemental indentures or other documents or instruments in form reasonably satisfactory to the Trustee; 
 (C) immediately after such transaction, no Default exists; and 
 (D) the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indentures, if any, comply with the Indenture; or 
 (ii) the
transaction is made in compliance with Section 4.10 of the Indenture; 
  

 3 

 (b) Subject to certain limitations described in the Indenture, the Successor Person will succeed to, and
be substituted for, the Guaranteeing Subsidiary under the Indenture and the Guaranteeing Subsidiary’s Guarantee. Notwithstanding the foregoing, the Guaranteeing Subsidiary may merge into or transfer all or part of its properties and assets to
another Guarantor or the Issuer. 
 (5) Releases. 
 The Guarantee of the Guaranteeing Subsidiary shall be automatically and unconditionally released and discharged, and no further action by the Guaranteeing Subsidiary, the Issuer or the Trustee is required for the
release of the Guaranteeing Subsidiary’s Guarantee, upon: 
 (1)(A) any sale, exchange or transfer (by merger or
otherwise) of the Capital Stock of the Guaranteeing Subsidiary (including any sale, exchange or transfer), after which the Guaranteeing Subsidiary is no longer a Restricted Subsidiary or all or substantially all the assets of the Guaranteeing
Subsidiary which sale, exchange or transfer is made in compliance with the applicable provisions of the Indenture; 
 (B) the
release or discharge of the guarantee by the Guaranteeing Subsidiary of the Senior Credit Facilities and any other guarantee which resulted in (or would by itself require) the creation of the Guarantee, except a discharge or release by or as a
result of payment under such guarantee; 
 (C) the proper designation of the Guaranteeing Subsidiary as an Unrestricted
Subsidiary; or 
 (D) the Issuers exercising their Legal Defeasance option or Covenant Defeasance option in accordance with
Article 8 of the Indenture or the Issuers’ obligations under the Indenture being discharged in accordance with the terms of the Indenture; and 
 (2) the Guaranteeing Subsidiary delivering to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent provided for in the Indenture relating to such transaction
have been complied with. 
 (6) No Recourse Against Others. No director, representative, officer, employee, incorporator or
stockholder of the Guaranteeing Subsidiary shall have any liability for any obligations of the Issuers or the Guarantors (including the Guaranteeing Subsidiary) under the Notes, any Guarantees, the Indenture or this Supplemental Indenture or for any
claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting Notes waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 
 (7) Governing Law. THIS SUPPLEMENTAL INDENTURE WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary.

paid by the Guaranteeing Subsidiary pursuant to the provisions of Section 2 hereof and Section 11.01 of the Indenture; provided that, if an Event of Default has occurred and is continuing, the Guaranteeing Subsidiary shall not be
entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts then due and payable by the Issuer under the Indenture or the Notes shall have been paid in full.

Guaranteeing Subsidiary acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and this Supplemental Indenture and that the guarantee and waivers made by it pursuant to this
