Exhibit 10.23


 


PHYSICIAN
Shareholder AGREEMENT


 


This PHYSICIAN shareholder
Agreement (this “Agreement”), dated as of March 28, 2014, is granted and delivered by Warren Hosseinion,
M.D. (“Shareholder”), a physician licensed under the laws of the State of California (the “State”),
in favor of Apollo Medical Management, Inc. a Delaware corporation (“Manager”), and Apollo Medical Holdings,
Inc., a Delaware corporation (“Apollo”), and for the account of Maverick Medical Group, Inc., a California professional
corporation (“Practice”). Capitalized terms used herein and not otherwise defined shall have the meanings given
such terms in the Management Agreement (as defined below).


 


BACKGROUND STATEMENT


 


A.          Practice is a professional entity
organized under the laws of the State to provide physician medical services. Shareholder is the legal and beneficial owner
of one hundred percent (100%) of the issued and outstanding stock in Practice (the “Shares”). Practice has entered
into that certain Amended and Restated Management Services Agreement dated as of the date hereof by and between Practice and Manager
(as amended or restated from time to time, the “Management Agreement”), pursuant to which Manager provides exclusive
management and administrative services to Practice.


 


B.          As the majority shareholder
of Practice, Shareholder will substantially benefit from Manager’s performance under the Management Agreement, including
Manager’s ability and requirement to extend credit to the Practice, and has the ability to impact Practice’s compliance
with certain terms of the Management Agreement. The purpose of this Agreement is to memorialize the agreement of Shareholder to
act in accordance with the Management Agreement, and to the extent of Shareholder’s personal authority, refrain from any
action or inaction that would result in a breach by Practice of its obligations under the Management Agreement.


 


C.          Pursuant to the Management Agreement,
Manager has the exclusive right to provide management and administrative services to Practice. Manager has expended, and will continue
to expend, significant resources, and has undertaken significant obligations, and will continue to incur significant obligations,
to be in a position to perform its obligations under the Management Agreement. In consideration of such services, Practice has
entered into certain covenants under the Management Agreement that assure Manager the exclusive right to provide management and
administrative services to Practice.


 


D.          Apollo, as the sole shareholder of
Manager, has the authority to cause Manager to enter into the Management Agreement. In light of the substantial benefits flowing
directly to Practice and indirectly to Shareholder from Manager’s performance of the Management Agreement, it is a condition
to Apollo’s causing Manager to enter into the Management Agreement that Shareholder execute and deliver this Agreement. Apollo
and Manager are relying on this Agreement in their decision for Manager to enter into the Management Agreement and Manager would
not enter into the Management Agreement without this Agreement.


 


E.          NNA of Nevada, Inc., a Nevada corporation
(“NNA”), is loaning money to Apollo pursuant to (i) a Credit Agreement between Apollo and NNA, dated on or about
the date hereof (as amended or restated from time to time, the “Credit Agreement”), and related Credit Documents
(as defined in the Credit Agreement) and (ii) a Convertible Secured Note made by Apollo in favor of NNA, dated on or about
the date hereof (as amended or restated from time to time, the “Convertible Note” and, collectively with the
Credit Agreement and other Credit Documents, the “Loan Documents”). NNA has required this Agreement to be executed
as a condition to entering into the Loan Documents. The proceeds of NNA’s loans to Apollo will provide substantial benefits
and assistance to Apollo and to Manager in the performance of Manager’s obligations under the Management Agreement, including
Manager’s obligation to extend credit to the Practice; consequently, Shareholder will receive substantial benefits from NNA’s
loans to Apollo.


 




    	 



    	 



    

 


STATEMENT OF AGREEMENT


 


NOW, THEREFORE, in consideration
of the foregoing recitals, which are incorporated herein, and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, and to induce Apollo to cause Manager to enter into the Management Agreement with Practice and
NNA to make loans to Apollo, Shareholder hereby agrees as follows:


 


ARTICLE
I


 


SHAREHOLDER
covenants


 


1.1          Compliance with Management Agreement
and Loan Documents.


 


(a)          Without limiting any other obligation
of Shareholder hereunder or of Practice under the Management Agreement, during the term of the Management Agreement, Shareholder
shall not take any action, or fail to take any action, in his or her capacity as a shareholder, director or officer of Practice,
that would cause Practice to breach the Management Agreement or any of the Loan Documents to which Practice is a party.


 


(b)          Whenever the Management Agreement
requires Manager and Practice to agree on the amount of the management fees payable by Practice under the Management Agreement,
Shareholder shall use his or her best efforts to cause Practice to negotiate in good faith and to reach an agreement on the amount
of such management fees.


 


(c)          Shareholder agrees to be responsible
for all damages suffered by Manager due to the affirmative actions or intentional omissions by Shareholder that result in a breach
by Practice of its obligations under the Management Agreement or any Loan Document (such that the breach would not have occurred
but for Shareholder’s affirmative action or intentional omission in connection therewith).


 


1.2          Exclusivity of Management Relationship.
Shareholder acknowledges the obligations set forth in Section 4.11.3 of the Management Agreement, pursuant to which Practice grants
Manager the right to provide exclusive management and administrative services to Practice. In furtherance of such obligations,
during the term of the Management Agreement, Shareholder agrees not to, directly or indirectly, whether through Practice or otherwise,
act as manager, employee, independent contractor, consultant, director, officer, agent, investor, lender, owner or similar capacity,
have an interest in or a financial relationship with, or be connected in any manner with, any medical practice engaged in the provision
of hospitalist or primary care services (a “Competing Practice”) within a 25-mile radius around any physician
office or health care facility where Practice provides services (the “Restricted Territory”) without first offering
Manager the exclusive right to provide management and administrative services to such Competing Practice substantially on the same
terms as set forth in the Management Agreement, or otherwise take any action that would deprive Manager of the bargained-for right
to provide the full scope of management and administrative services to Practice.


 




    	 



    	 



    

 


1.3          Agreements with Employees.

1.4          Non-Solicitation. In furtherance

the following: (i) the issuance by Practice of additional Shares or other equity interests or (ii) the sale, transfer, redemption,
pledge or other hypothecation of any Shares unless, in each case described in clauses (i) and (ii), the recipient or transferee
is permitted under State law to be a shareholder of Practice, and such transaction does not violate any term of the Loan Documents;


 


(b)          not to cause or consent to any transaction
described in Sections 1.5(a)(i) or 1.5(a)(ii) above whereby Shareholder would own less than seventy-five percent (75%) of the total
outstanding shares of Practice unless the recipient or transferee as well as all other shareholders of Practice becomes a party
to a Physician Shareholder Agreement substantially in the form of this Agreement or in such other form as otherwise agreed by Manager
and Apollo, in their sole discretion the transaction; and


 


(c)          to place a restrictive legend on
any certificates representing Shares that reads substantially as follows:


 


The shares represented by this certificate, and the
transfer thereof, are subject to the provisions of a Physician Shareholder Agreement in favor of Apollo Medical Holdings, Inc.
and Apollo Medical Management, Inc., dated as of March 28, 2014, as amended from time to time, a copy of which is on file
in, and may be examined at, the principal office of Practice.


 


1.6          General.


 


(a)          Shareholder agrees that his obligations
hereunder are absolute and unconditional, and such obligations shall not be discharged, limited or otherwise affected by (i) any
amendment, modification, supplement to, discharge or waiver of any provisions of the Management Agreement or Loan Documents or
(ii) any other circumstance that might otherwise constitute a legal or equitable discharge or defense available to Practice or
Shareholder.


 


(b)          No obligation of Shareholder hereunder
shall be discharged other than by complete performance of such obligation.


 


(c)          Shareholder agrees that, pursuant

irrevocable stock power with regard to its stock in Practice, (ii) an undated and signed resignation of Shareholder’s position
as officer and/or director, as applicable, of Practice, and (iii) Shareholder’s stock certificate in Practice.

ARTICLE
II


 


APOLLO’S
ACQUISITION RIGHT


 


2.1          Apollo’s Acquisition Right.
In support and furtherance of Shareholder’s obligations under this Agreement and for the consideration received herewith,
Shareholder agrees that at any time during the term of this Agreement, Apollo may designate a third party who is permitted under
California law to be a shareholder of Practice (a “Permitted Transferee”) with the right (the “Acquisition
Right”) (a) to acquire Shareholder’s Shares for a purchase price of $100.00, or (b) to acquire from Practice, for
a purchase price of $100.00, a number of equity interests in Practice that, if issued to the Permitted Transferee, would result
in such Permitted Transferee’s holding a 51% ownership interest in Practice. In furtherance of the above, the parties agree
that the proposed purchase price of $100 under either subsection (a) or (b) above shall be subject to confirmation by Apollo that
such purchase price is fair market value. If Apollo determines that such purchase price is not fair market value, the option exercise
price shall be an amount that is fair market value as determined by Apollo, in its sole discretion. The Acquisition Right shall
be exercisable by Apollo by delivering written notice of such exercise and payment to Shareholder or Practice, as applicable, and
upon exercise, Shareholder shall be obligated to assign and transfer the Shares or to cause Practice to issue new equity interests
(as applicable), free and clear of all liens, encumbrances, claims of third parties, security interests, mortgages, pledges, agreements,
options and rights of others of any kind whatsoever, whether or not filed, recorded or perfected. At any time an “Event of
Default” is in existence under the Loan Documents, NNA shall have the right to require Apollo to exercise its Acquisition
Right in favor of a Permitted Transferee approved by NNA. NNA may exercise this right by delivering written notice to Apollo, and
Apollo shall exercise the Acquisition Right in favor of a Permitted Transferee approved by NNA within 10 business days of receiving
such written notice from NNA.


 


2.2          Noncompetition. Shareholder
agrees that for a period of two years after the transfer of all of Shareholder’s Shares in Practice in connection with the
exercise of the Acquisition Right set forth in Section 2.1, Shareholder shall not, directly or indirectly, (i) act as manager,
employee, independent contractor, consultant, director, officer, agent, investor, lender, owner or similar capacity, have an interest
in or a financial relationship with, or be connected in any manner with, any Competing Practice within the Restricted Territory,
or (ii) solicit any patients, employees, customers or clients of Practice.


 


ARTICLE
III


 


general


 


3.1          Term. This Agreement shall
remain in full force and effect until such time as Shareholder no longer holds an ownership interest in any capital stock or other
equity interests of Practice due to a transfer of any such equity interests as expressly permitted hereunder; provided, that the
provisions set forth in Sections 1.4 and 2.2 and in Article III of this Agreement shall survive termination.


 




    	 



    	 



    

 


3.2          Arbitration. Any dispute hereunder
shall be settled exclusively by binding arbitration before a single arbitrator in accordance with the Rules of Procedure for Arbitration
of the American Health Lawyers Association (AHLA) Alternative Dispute Resolution Service, and judgment upon the award rendered
by the arbitrator may be entered in any court having jurisdiction thereof. Such arbitration shall occur in the city where Practice
is located within sixty (60) days after a party gives notice to the other party of its election to trigger this arbitration clause.
The arbitrator shall be chosen in accordance with the rules of the AHLA Alternative Dispute Resolution Service then in effect.
If the AHLA Alternative Dispute Resolution Service is no longer in effect, then the arbitration shall be conducted as set out above
by the American Arbitration Association in accordance with the Commercial Rules of the American Arbitration Association then in
effect. The arbitrator may award attorneys’ fees and costs to the prevailing party. The parties shall share the costs of
the arbitrator equally between them. Each party shall bear its own expenses of preparation for and participation in arbitration.
The statute of limitations applicable to any claim shall be determined as if such claim were being asserted in the State where
Practice is located, and such statute of limitations shall apply to preclude arbitration of any claim hereunder not brought within
the applicable limitation period. Notwithstanding anything herein to the contrary, the parties reserve the right to proceed at
any time in any court having jurisdiction or by self-help to exercise or prosecute the following remedies, as applicable: (i) all
rights of self-help, including peaceful occupation of real property and collection of rents, set off, and peaceful possession of
personal property, (ii) pre-judgment garnishment or attachment of property, (iii) a preliminary injunction or temporary restraining
order to preserve the status quo or to enforce a party’s rights under any provision set forth herein, and (iv) when applicable,
a judgment by confession of judgment. Preservation of these remedies does not limit the power of the arbitrator to grant similar
remedies that may be requested by a party in a dispute. The agreement to arbitrate set forth in this Section may only be enforced
by the parties to this Agreement and their permitted successors and assigns, shall survive the termination or breach of this Agreement,
and shall be construed pursuant to and governed by the provisions of the Federal Arbitration Act, 9 U.S.C. §1, et seq.


 


3.3          Waiver of Jury Trial. To the
fullest extent permitted by law, the parties hereby waive the right to trial by jury.


 


3.4          Entire Agreement. This Agreement
expresses the entire agreement between the parties hereto regarding the subject matter hereof and supersedes any prior or contemporaneous
written or oral understanding or agreement.


 


3.5          Legal Events. If any law is
adopted or amended or any rule or regulation is published for public comment, promulgated or modified, any administrative ruling,
advisory opinion or judicial interpretation in any jurisdiction is issued or modified or any court or administrative tribunal in
any jurisdiction issues any decision, judgment, order or interpretation, which, in the reasonable judgment of one party draws into
question the terms of this Agreement in a manner that may materially and adversely affect a party’s or any party’s
affiliate’s licensure, accreditation, certification, or ability to bill, to claim, to present a bill or claim, or to receive
payment or reimbursement from any payor or that may subject such party to a substantial risk of prosecution or civil monetary penalty,
then the parties shall modify this Agreement to the minimum extent necessary to eliminate the illegal or unenforceable aspects
hereof, while remaining consistent with the intent of this Agreement in its original form.


 


3.6          Amendments; Waivers. No amendment,
modification, or waiver of any provision of this Agreement shall be binding unless in writing and signed by the party against whom
the operation of such amendment, modification, or waiver is sought to the enforced. No delay in the exercise of any right shall
be deemed a waiver thereof, and no waiver of a right or remedy in a particular instance shall constitute a waiver of such right
or remedy generally. In addition, this Agreement shall not be amended, terminated, supplemented or superseded without the consent
of (i) Apollo’s Board of Directors or (ii) so long as any obligations or lending commitments are outstanding under the Loan
Documents, NNA.


 




    	 



    	 



    

 


3.7          Waiver. No term of this Agreement,
and no breach of this Agreement, shall be waived, altered or modified except by written instrument signed by the party sought to
be bound thereby. A waiver of any breach on any one occasion shall not constitute a waiver of any other or subsequent breach whether
of like or different nature. No delay or failure by any party to insist upon the strict performance of any term of this Agreement,
or to exercise any right or remedy available upon any breach of this Agreement, shall operate as a waiver thereof, and no single
or partial exercise of any right or remedy under this Agreement shall preclude other or further exercise thereof or the exercise
of any other right, power or privilege. No course of dealing between the parties shall be effective to change, modify or discharge
any provision of this Agreement or to constitute a waiver of any default hereunder.


 


3.8          Assignment. Neither Practice
nor Shareholder shall assign this Agreement or any of its rights or obligations under this Agreement without the prior written
consent of Apollo. Each of Apollo and Manager shall have a right to assign this Agreement in connection with a transfer of all
or substantially all of such party’s business, whether by sale, merger or otherwise. Shareholder specifically agrees that
Manager shall have the right to perform its obligations hereunder through any affiliate without Shareholder’s consent. Practice,
Shareholder and Manager acknowledge and agree that Apollo shall have the right to assign this Agreement as collateral to NNA under
the Loan Documents, and NNA shall have the right to enforce NNA’s and Apollo’s rights under this Agreement at any time
an “Event of Default” is in existence under the Loan Documents.


 


3.9          Successors and Assigns. All
of the provisions herein contained shall be binding upon and inure to the benefit of the heirs, successors and permitted assigns
of the parties hereto to the same extent as if such heirs, successors and permitted assigns were in each case named as a party
to this Agreement.


 


3.10          Severability. If any provision
contained in this Agreement shall for any reason be held invalid, illegal or unenforceable in any respect, such invalidity, illegality
or unenforceability shall not affect any other provision of this Agreement, but this Agreement shall be construed as if such invalid,
illegal or unenforceable provision had never been contained therein, except as otherwise expressly provided in this Agreement.
The parties hereto agree that if a court determines that any of the covenants contained herein is unreasonable, void or invalid
for any reason whatsoever, then such covenant shall be modified as the court, or jury if applicable, shall determine to be fair
and reasonable, IT BEING THE INTENT OF THE PARTIES HERETO TO BE SUBJECT TO AN AGREEMENT FOR THE NECESSARY PROTECTION OF THE LEGITIMATE
INTERESTS OF APOLLO AND MANAGER, WHICH IS NOT UNDULY HARSH IN CURTAILING THE LEGITIMATE RIGHTS OF SHAREHOLDER. Shareholder acknowledges
and agrees that the provisions herein do not deprive him/her of the ability to find employment and maintain a reasonable personal
income.


 


3.11          Covenants Independent. The
covenants contained herein shall be construed as independent agreements and the existence of any claim which Shareholder may have
against Apollo, Manager or NNA will not constitute a defense to the enforcement by Apollo, Manager or NNA by injunctive relief
or otherwise, of the provisions contained herein.


 


3.12          Notices. Any notices required
or permitted to be given under this Agreement shall be given in writing to each other party and shall be deemed to be given (i)
