the Company or any subsidiary or any property or assets owned or leased by the Company or any subsidiary before or by any court or

court, domestic or foreign, relating to the use, disposal or release of hazardous or toxic substances or relating to the protection or
restoration of the environment or human exposure to hazardous or toxic substances (collectively, “Environmental Laws”),
owns or operates any real property contaminated with any substance that is subject to any environmental laws, is liable for any off-site
disposal or contamination pursuant to any Environmental Laws, or is subject to any claim relating to any Environmental Laws, which violation,
contamination, liability or claim would individually or in the aggregate, have a Material Adverse Effect; and the Company is not aware
of any pending investigation which might lead to such a claim. Neither the Company nor any of its subsidiaries anticipates incurring any
material capital expenditures relating to compliance with Environmental Laws.

 

(m)             Ownership
of Assets. The Company and its subsidiaries have good and marketable title to all property (whether real or personal) described
in the Registration Statement, the Prospectus and the Prospectus Supplement as being owned by them, in each case free and clear of
all liens, claims, security interests, other encumbrances or defects except such as are described in the Registration Statement, the

Intellectual Property (as defined below) necessary for the conduct of the Company’s and it subsidiaries’ business as now conducted
or as described in the Registration Statement, the Prospectus and the Prospectus Supplement to be conducted, except as such failure to

Statement, the Prospectus and the Prospectus Supplement, (A) to the Knowledge (as defined herein) of the Company, there is no infringement,
misappropriation or violation by third parties of any such Intellectual Property, except as such infringement, misappropriation or violation
would not result in a Material Adverse Effect; (B) there is no pending or, to the Knowledge of the Company, threatened, action, suit,

Property, and the Company is unaware of any objective facts which would form a reasonable basis for any such claim; (C) the Intellectual

The Company and each of its subsidiaries carries, or is covered by, insurance from reputable insurers in such amounts and covering
such risks as is adequate for the conduct of its business and the value of its properties and the properties of its subsidiaries and

force and effect; the Company and its subsidiaries are in compliance with the terms of such policies and instruments in all material
respects; there are no claims by the Company or any of its subsidiaries under any such policy or instrument as to which any

    13

     

    

 

(p)              
Internal Accounting Controls. The Company and its subsidiaries maintain a system of internal accounting controls sufficient
to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization;
(ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting
principles in the United States and to maintain accountability for assets; (iii) access to assets is permitted only in accordance
with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing
assets at reasonable intervals and appropriate action is taken with respect to any differences. Except as disclosed in the Registration
Statement, the Prospectus and the Prospectus Supplement, the Company’s internal control over financial reporting is effective and
none of the Company, its board of directors and audit committee is aware of any “significant deficiencies” or “material
weaknesses” (each as defined by the Public Company Accounting Oversight Board) in its internal control over financial reporting,
or any fraud, whether or not material, that involves management or other employees of the Company and its subsidiaries who have a significant
role in the Company’s internal controls; and since the end of the latest audited fiscal year, there has been no change in the Company’s
internal control over financial reporting (whether or not remediated) that has materially affected, or is reasonably likely to materially
affect, the Company’s internal control over financial reporting. The Company’s board of directors has, subject to the exceptions,
cure periods and the phase in periods specified in the applicable stock exchange rules (“Exchange Rules”),
validly appointed an audit committee to oversee internal accounting controls whose composition satisfies the applicable requirements of
the Exchange Rules and the Company’s board of directors and/or the audit committee has adopted a charter that satisfies the requirements
of the Exchange Rules.

 

(q)              
Certain Fees. Except as set forth in the Prospectus Supplement, no brokerage or finder’s fees or commissions are or
will be payable by the Company or any subsidiary to any broker, financial advisor or consultant, finder, placement agent, investment banker,
bank or other Person with respect to the transactions contemplated by the Transaction Documents. The Purchaser shall have no obligation
with respect to any fees or with respect to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section
that may be due in connection with the transactions contemplated by the Transaction Documents.

 

(r)               
Investment Company. The Company is not and, after giving effect to the offering and sale of the Securities, will not be
an “investment company,” as such term is defined in the Investment Company Act of 1940, as amended.

 

    14

     

    

 

(s)               
 Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange
Act, and the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration
of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating
such registration. The Company has not, in the 12 months preceding the date hereof, received notice from any Trading Market on which the
Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance requirements
of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue to be, in compliance
with all such listing and maintenance requirements. The Common Stock is currently eligible for electronic transfer through the Depository
Trust Company or another established clearing corporation and the Company is current in payment of the fees to the Depository Trust Company
(or such other established clearing corporation) in connection with such electronic transfer.

 

(t)                
Application of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in
order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents)
or the laws of its state of incorporation that is or could become applicable to the Purchaser as a result of the Purchaser and the Company
fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation as a result of the
Company’s issuance of the Securities and the Purchaser’s ownership of the Securities up to a Beneficial Ownership level of
9.99%.

 

(u)               Disclosure.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company
confirms that neither it nor any other Person acting on its behalf has provided to the Purchaser or its agents or counsel with any
information that it believes constitutes or might constitute material, non-public information which is not otherwise disclosed in
the Prospectus Supplement. The Company understands and confirms that the Purchaser will rely on the foregoing representation in
effecting transactions in securities of the Company. All of the disclosure furnished by or on behalf of the Company to the Purchaser
regarding the Company and its subsidiaries, their respective businesses and the transactions contemplated hereby, including the
Disclosure Schedules to this Agreement, when taken together as a whole, is true and correct and does not contain any untrue
statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light
of the circumstances under which they were made, not misleading. The press releases disseminated by the Company during the twelve
months preceding the date of this Agreement taken as a whole do not contain any untrue statement of a material fact or omit to state
a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the
circumstances under which they were made and when made, not misleading. The Company acknowledges and agrees that no Purchaser makes
or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set
forth in Section 3.2 hereof.

 

    15

     

    

 

(v)              
No Integrated Offering. Assuming the accuracy of the Purchaser’s representations and warranties set forth in Section
3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any
offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the
Securities to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions of any
Trading Market on which any of the securities of the Company are listed or designated.

 

(w)            
Solvency. Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the
receipt by the Company of the proceeds from the sale of the Securities hereunder and the receipt of $7,500,000 from the offering and sale
of Series X Convertible Preferred Stock to DaVita, Inc., (i) the fair saleable value of the Company’s assets exceeds the amount
that will be required to be paid on or in respect of the Company’s existing debts and other liabilities (including known contingent
liabilities) as they mature, (ii) the Company’s assets do not constitute unreasonably small capital to carry on its business as
now conducted and as proposed to be conducted including its capital needs taking into account the particular capital requirements of the
business conducted by the Company, consolidated and projected capital requirements and capital availability thereof, and (iii) the current
cash flow of the Company, together with the proceeds the Company would receive, were it to liquidate all of its assets, after taking into
account all anticipated uses of the cash, would be sufficient to pay all amounts on or in respect of its liabilities when such amounts
are required to be paid. The Company does not intend to incur debts beyond its ability to pay such debts as they mature (taking into account
the timing and amounts of cash to be payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances
which lead it to believe that it will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction
within one year from the Closing Date. The SEC Reports set forth as of the date hereof all outstanding secured and unsecured Indebtedness
of the Company or any subsidiary, or for which the Company or any subsidiary has commitments. For the purposes of this Agreement, “Indebtedness”
means (x) any liabilities for borrowed money or amounts owed in excess of $50,000 (other than trade accounts payable incurred in the ordinary
course of business), (y) all guaranties, endorsements and other contingent obligations in respect of indebtedness of others, whether or
not the same are or should be reflected in the Company’s consolidated balance sheet (or the notes thereto) or disclosed the SEC
Reports, except guaranties by endorsement of negotiable instruments for deposit or collection or similar transactions in the ordinary
course of business; and (z) the present value of any lease payments in excess of $50,000 due under leases required to be capitalized in
accordance with United States generally accepted accounting principles. Neither the Company nor any subsidiary is in default with respect
to any Indebtedness.

 

    16

     

    

 

(x)               Tax
Status. The Company and its subsidiaries (A) have timely filed all federal, state, local and foreign income and franchise tax
returns required to be filed and (B) are not in default in the payment of any taxes which were payable pursuant to said returns or
any assessments with respect thereto, other than any which the Company or any of its subsidiaries is contesting in good faith;
except those, in each of the cases described in clauses (A) and (B) of this paragraph (x), that would not, singularly or in the
aggregate, have a Material Adverse Effect. There is no pending dispute with any taxing authority relating to any of such returns,
and the Company has no knowledge of any proposed liability for any tax to be imposed upon the properties or assets of the Company
for which there is not an adequate reserve reflected in the Company’s financial statements included in the Registration
Statement, the Prospectus and the Prospectus Supplement.

 

(y)              
Anti-Bribery and Anti-Money Laundering Laws. Each of the Company, its subsidiaries, its affiliates and any of their respective
officers, directors, supervisors, managers, agents, or employees, each in their respective roles with the Company, has not violated, its
participation in the offering will not violate, and the Company and each of its subsidiaries has instituted and maintains policies and
procedures designed to ensure continued compliance with, each of the following laws: anti-bribery laws, including but not limited to,
any applicable law, rule, or regulation of any locality in which the Company does business, including but not limited to any applicable
law, rule, or regulation promulgated to implement the OECD Convention on Combating Bribery of Foreign Public Officials in International
Business Transactions, signed December 17, 1997, including the U.S. Foreign Corrupt Practices Act of 1977 (the “FCPA”),
as amended, the U.K. Bribery Act 2010 (to the extent applicable), or any other applicable law, rule or regulation of similar purposes
and scope, or anti-money laundering laws, including but not limited to, applicable federal, state, international, foreign or other laws,
regulations or government guidance regarding anti-money laundering, including, without limitation, Title 18 US. Code section 1956 and
1957, the Patriot Act, the Bank Secrecy Act, and international anti-money laundering principles or procedures by an intergovernmental
group or organization, such as the Financial Action Task Force on Money Laundering, of which the United States is a member and with which
designation the United States representative to the group or organization continues to concur, all as amended, and any executive order,
directive, or regulation pursuant to the authority of any of the foregoing, or any orders or licenses issued thereunder.

 

(z)              
Acknowledgment Regarding Purchaser’s Purchase of Securities. The Company acknowledges and agrees that the Purchaser
is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated
thereby. The Company further acknowledges that the Purchaser is not acting as a financial advisor or fiduciary of the Company (or in any
similar capacity) with respect to the Transaction Documents and the transactions contemplated thereby and any advice given by the Purchaser
or any of its respective representatives or agents in connection with the Transaction Documents and the transactions contemplated thereby
is merely incidental to the Purchaser’s purchase of the Securities. The Company further represents to the Purchaser that the Company’s
decision to enter into this Agreement and the other Transaction Documents has been based solely on the independent evaluation of the transactions
contemplated hereby by the Company and its representatives.

 

    17

     

    

 

(aa)           
Acknowledgment Regarding Purchaser’s Trading Activity. Anything in this
Agreement or elsewhere herein to the contrary notwithstanding (except for Sections 3.2(f) and 4.14 hereof), it is understood and
acknowledged by the Company that: (i) the Purchaser has not been asked by the Company to agree, nor has the Purchaser agreed, to desist
from purchasing or selling, long and/or short, securities of the Company, or “derivative” securities based on securities
issued by the Company or to hold the Securities for any specified term; (ii) past or future open market or other transactions by the
Purchaser, specifically including, without limitation, Short Sales or “derivative” transactions, before or after the closing
of this or future private placement transactions, may negatively impact the market price of the Company’s publicly-traded securities;
(iii) the Purchaser, and counter-parties in “derivative” transactions, if any, to which the Purchaser is a party, directly
or indirectly, presently may have a “short” position in the Common Stock, and (iv) the Purchaser shall not be deemed to have
any affiliation with or control over any arm’s length counter-party in any “derivative” transaction. The Company further
understands and acknowledges that (y) the Purchaser may engage in hedging activities at various times during the period that the Securities
are outstanding, and (z) such hedging activities (if any) could reduce the value of the existing stockholders’ equity interests
in the Company at and after the time that the hedging activities are being conducted. The Company acknowledges that such aforementioned
hedging activities do not constitute a breach of any of the Transaction Documents.

 

(bb)          
Regulation M Compliance.  The Company has not, and to its knowledge no one acting on its behalf has, (i) taken, directly
or indirectly, any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company
to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or, paid any compensation for soliciting purchases
of, any of the Securities, or (iii) paid or agreed to pay to any Person any compensation for soliciting another to purchase any other
securities of the Company, other than, in the case of clauses (ii) and (iii), compensation paid to the Company’s placement agent
in connection with the placement of the Securities.

 

(cc)            FDA
and Regulatory Matters. Except as set forth in the Prospectus and the Prospectus Supplement, there is no legal or governmental
proceeding to which the Company or any of its subsidiaries is a party or of which any property or assets of the Company or any of
its subsidiaries or any officer or director of the Company, in their roles as such, or any employee benefit plan sponsored by the
Company, is the subject, including any proceeding before the United States Food and Drug Administration of the U.S. Department of
Health and Human Services (the “FDA”) or comparable federal, state, local or foreign governmental
authorities (it being understood that the interaction between the Company and the FDA and such comparable governmental bodies
relating to the clinical development and product approval process shall not be deemed proceedings for purposes of this
representation), which is required to be described in the Registration Statement, the Prospectus or the Prospectus Supplement or a
document incorporated by reference therein and is not described therein, or which, singularly or in the aggregate, if determined
adversely to the Company or any of its subsidiaries, could reasonably be expected to have a Material Adverse Effect; and to the
Company’s knowledge after reasonable investigation (“Knowledge”), no such proceedings are threatened by
governmental authorities. The Company is in compliance with all applicable federal, state, local and foreign laws, regulations,
orders and decrees governing its business as prescribed by the FDA, or any other federal, state or foreign agencies or bodies
engaged in the regulation of pharmaceuticals or biohazardous substances or materials, except where noncompliance would not, singly
or in the aggregate, have a Material Adverse Effect. All preclinical and clinical studies conducted by or on behalf of the Company
to support approval for commercialization of the Company’s products have been conducted by the Company, or to the
Company’s Knowledge by third parties, in compliance with all applicable federal, state or foreign laws, rules, orders and
regulations, except for such failure or failures to be in compliance as could not reasonably be expected to have, singularly or in
the aggregate, a Material Adverse Effect.

 

    18

     

    

 

The
Company and each of its subsidiaries possess all licenses, certificates, authorizations and permits issued by, and have made all declarations
and filings with, the appropriate local, state, federal or foreign governmental or regulatory agencies or bodies (including, without limitation,
those administered by the FDA or by any foreign, federal, state or local governmental or regulatory authority performing functions similar
to those performed by the FDA) that are necessary for the ownership or lease of their respective properties or the conduct of their respective
businesses as described in the Registration Statement, the Prospectus and the Prospectus Supplement (collectively, the “Governmental
Permits”), except where any failures to possess or make the same would not, singularly or in the aggregate, have a Material
Adverse Effect. The Company and its subsidiaries are in compliance with all such Governmental Permits and all such Governmental Permits
are valid and in full force and effect, except where the noncompliance, validity or failure to be in full force and effect would not,
singularly or in the aggregate, have a Material Adverse Effect. Neither the Company nor any subsidiary has received notification of any
revocation, modification, suspension, termination or invalidation (or proceedings related thereto) of any such Governmental Permit and
to the Knowledge of the Company, no event has occurred that allows or results in, or after notice or lapse of time or both would allow
or result in, revocation, modification, suspension, termination or invalidation (or proceedings related thereto) of any such Governmental
Permit and the Company has no reason to believe that any such Governmental Permit will not be renewed, except where such revocation, modification,
suspension, termination, invalidation or nonrenewal would not, singularly or in the aggregate, have a Material Adverse Effect.

 

The
Company and its subsidiaries, and to the Company’s Knowledge, its directors, officers, employees or agents, each in their respective
roles with the Company, are and have been in compliance in all material respects with applicable federal, state, local and foreign health
care regulatory laws, including without limitation, laws related to fraud and abuse, payment transparency, and privacy and security of
protected health information (collectively, “Health Care Laws”). The Company and its subsidiaries have not received
written notice of any claim, action, suit, proceeding, hearing, enforcement, investigation, arbitration or other action from any court,
arbitrator or governmental or regulatory authority or third party alleging that the Company, its subsidiaries or its personnel have violated
any applicable Health Care Law, nor, to the Company’s Knowledge, has any such claim, action, suit, proceeding, hearing, enforcement,
investigation, arbitration or other action been threatened, which, individually or in the aggregate, might result in any Material Adverse
Effect.

 

    19

     

    

 

The
studies, tests and preclinical or clinical trials conducted by or on behalf of the Company that are described in the Prospectus and the
Prospectus Supplement (the “Company Studies and Trials”) were and, if still pending, are being conducted in all material
respects in accordance with experimental protocols, procedures and controls pursuant to, where applicable, accepted professional scientific
standards; the descriptions of the results of the Company Studies and Trials contained or incorporated by reference in the Registration
Statement, the Prospectus and the Prospectus Supplement are accurate in all material respects; the Company has no knowledge of any other
studies or trials not described in the Prospectus and the Prospectus Supplement, the results of which are inconsistent with or call in
question the results described or referred to in the Registration Statement, the Prospectus and the Prospectus Supplement; and the Company
has not received any notices or correspondence from the FDA or any foreign, state or local governmental authority exercising comparable
authority requiring the termination, suspension or material modification of any Company Studies and Trials that termination, suspension
or material modification would reasonably be expected to have a Material Adverse Effect and, to the Company’s Knowledge, there are
no reasonable grounds for the same.

 

Except as disclosed
in the Registration Statement, the Prospectus and the Prospectus Supplement, the Company has not granted rights to develop, manufacture,
produce, assemble, distribute, license, market or sell its products or product candidates to any other person and is not bound by any

its products or product candidates.

Stock Option Plans. Except as described in the Registration Statement, the Prospectus and the Prospectus Supplement, there
are no options, warrants, restricted stock units, agreements, contracts or other rights in existence to purchase or acquire from the Company
or any subsidiary of the Company any shares of the capital stock of the Company or any subsidiary of the Company. The description of the
Company’s stock option, stock bonus and other stock plans or arrangements (the “Company Stock Plans”), and the
options (the “Options”) or other rights granted thereunder, set forth in the Registration Statement, the Prospectus
and the Prospectus Supplement accurately and fairly presents the information required to be shown with respect to such plans, arrangements,
options and rights. Each grant of an Option (A) was duly authorized no later than the date on which the grant of such Option was by its
terms to be effective by all necessary corporate action, including, as applicable, approval by the board of directors of the Company (or
a duly constituted and authorized committee thereof) and any required shareholder approval by the necessary number of votes or written
consents, and the award agreement governing such grant (if any) was duly executed and delivered by each party thereto and (B) was
made in accordance with the terms of the applicable Company Stock Plan, and all applicable laws and regulatory rules or requirements,
including all applicable federal securities laws.

 

(ee)            Office
of Foreign Assets Control. Neither the Company nor any subsidiary nor, to the Company’s knowledge, any director, officer,
agent, employee or affiliate of the Company or any subsidiary is currently subject to any U.S. sanctions administered by the Office
of Foreign Assets Control of the U.S. Treasury Department (“OFAC”).

request.

five percent (5%) or more of the outstanding shares of any class of voting securities or twenty-five percent (25%) or more of the total

anticipated by the Company to arise, between the Company and the accountants and lawyers formerly or presently employed by the Company

3.2             
Representations and Warranties of the Purchaser. The Purchaser hereby represents and warrants as of the date hereof and
as of the Closing Date to the Company as follows (unless as of a specific date therein, in which case they shall be accurate as of such
date):

 

(a)              
Organization; Authority. The Purchaser is either an individual or an entity duly incorporated or formed, validly existing
and in good standing under the laws of the jurisdiction of its incorporation or formation with full right, corporate, partnership, limited
liability company or similar power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents
and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of the Transaction Documents and performance
by the Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership,
limited liability company or similar action, as applicable, on the part of the Purchaser. Each Transaction Document to which it is a party
has been duly executed by the Purchaser, and when delivered by the Purchaser in accordance with the terms hereof, will constitute the
valid and legally binding obligation of the Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by
general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting
enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive
relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

 

    21

     

    

 

(b)              
 Understandings or Arrangements. The Purchaser is acquiring the Securities as principal for its own account and has no direct
or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities (this
representation and warranty not limiting the Purchaser’s right to sell the Securities pursuant to the Registration Statement or
otherwise in compliance with applicable federal and state securities laws). The Purchaser is acquiring the Securities hereunder in the
ordinary course of its business.

 

(c)              
Purchaser Status. At the time the Purchaser was offered the Securities, it was, and as of the date hereof it is, and on
each date on which it exercises any Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1),
(a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a)
under the Securities Act.

 

(d)              
Experience of the Purchaser. The Purchaser, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment
in the Securities, and has so evaluated the merits and risks of such investment. The Purchaser is able to bear the economic risk of an
investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

 

(e)              
Access to Information. The Purchaser acknowledges that it has had the opportunity to review the Transaction Documents (including
all exhibits and schedules thereto) and the SEC Reports and has been afforded, (i) the opportunity to ask such questions as it has deemed
necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Securities
and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial condition, results
of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment; and (iii) the opportunity
to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary
to make an informed investment decision with respect to the investment. The Purchaser acknowledges and agrees that neither the Placement
Agent nor any Affiliate of the Placement Agent has provided the Purchaser with any information or advice with respect to the Securities
nor is such information or advice necessary or desired. Neither the Placement Agent nor any Affiliate has made or makes any representation
as to the Company or the quality of the Securities and the Placement Agent and any Affiliate may have acquired non-public information
with respect to the Company which the Purchaser agrees need not be provided to it. In connection with the issuance of the Securities to
the Purchaser, neither the Placement Agent nor any of its Affiliates has acted as a financial advisor or fiduciary to the Purchaser.

 

(f)                Certain
Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, the Purchaser has not, nor
has any Person acting on behalf of or pursuant to any understanding with the Purchaser, directly or indirectly executed any
purchases or sales, including Short Sales, of the securities of the Company during the period commencing as of the time that the
Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting forth
the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Other than to
other Persons party to this Agreement or to the Purchaser’s representatives, including, without limitation, its officers,
directors, partners, legal and other advisors, employees, agents and Affiliates, the Purchaser has maintained the confidentiality of
all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).
Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute a representation or warranty,
or preclude any actions, with respect to locating or borrowing shares in order to effect Short Sales or similar transactions in the
future.

 

    22

     

    

 

The Company acknowledges and
agrees that the representations contained in this Section 3.2 shall not modify, amend or affect the Purchaser’s right to rely on
the Company’s representations and warranties contained in this Agreement or any representations and warranties contained in any
other Transaction Document or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation
of the transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute
a representation or warranty, or preclude any actions, with respect to locating or borrowing shares in order to effect Short Sales or
similar transactions in the future.

statement to cover the issuance or resale of the Warrant Shares or if the Pre-Funded Warrant is exercised via cashless exercise, the Warrant
Shares issued pursuant to any such exercise shall be issued free of all legends. If at any time following the date hereof the Registration
Statement (or any subsequent registration statement registering the sale or resale of the Warrant Shares) is not effective or is not otherwise
available for the sale or resale of the Warrant Shares, the Company shall immediately notify the holders of the Pre-Funded Warrants in
writing that such registration statement is not then effective and thereafter shall promptly notify such holders when the registration
statement is effective again and available for the sale or resale of the Warrant Shares (it being understood and agreed that the foregoing
shall not limit the ability of the Company to issue, or the Purchaser to sell, any of the Warrant Shares in compliance with applicable
federal and state securities laws). The Company shall use reasonable best efforts to keep a registration statement (including the Registration
Statement) registering the issuance of the Warrant Shares effective during the term of the Pre-Funded Warrants.

 

4.2             
Furnishing of Information. Until the earlier of the time that (i) the Purchaser owns no Securities and (ii) the Pre-Funded
Warrants have been exercised in full or expired, the Company covenants to timely file (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act
even if the Company is not then subject to the reporting requirements of the Exchange Act.

 

4.3              Integration.
The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in
Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities for purposes of the rules and

the Company represents to the Purchaser that it shall have publicly disclosed all material, non-public information delivered to the Purchaser
by the Company or any of its subsidiaries, or any of their respective officers, directors, employees or agents in connection with the
transactions contemplated by the Transaction Documents. The Company covenants and agrees that neither it, nor any other Person acting

believes constitutes, material non-public information, unless prior thereto the Purchaser shall have consented to the receipt of such
information and agreed with the Company to keep such information confidential. The Company understands and confirms that the Purchaser
shall be relying on the foregoing covenant in effecting transactions in securities of the Company. In addition, effective upon the issuance
of such press release, the Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement,
whether written or oral, between the Company, any of its subsidiaries or any of their respective officers, directors, agents, employees
or Affiliates on the one hand, and the Purchaser or any of its Affiliates on the other hand, shall terminate. The Company and the Purchaser
shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the
Company nor the Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of
the Company, with respect to any press release of the Purchaser, or without the prior consent of the Purchaser, with respect to any press
release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in
which case the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. Notwithstanding
the foregoing, the Company shall not publicly disclose the name of the Purchaser, or include the name of the Purchaser in any filing with
the Commission or any regulatory agency or Trading Market, without the prior written consent of the Purchaser, except (a) as required
by federal securities law in connection with the filing of final Transaction Documents with the Commission and (b) to the extent such
disclosure is required by law or Trading Market regulations, in which case the Company shall provide the Purchaser with prior notice of
such disclosure permitted under this clause (b).

Person, that the Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison
pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted
by the Company, or that the Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving
Securities under the Transaction Documents or under any other agreement between the Company and the Purchaser.

 

    24

Transaction Documents, which shall be disclosed pursuant to Section 4.4, the Company covenants and agrees that neither it, nor any other
Person acting on its behalf will provide the Purchaser or its agents or counsel with any information that constitutes, or the Company
reasonably believes constitutes, material non-public information, unless prior thereto the Purchaser shall have consented to the receipt
of such information and agreed with the Company to keep such information confidential. The Company understands and confirms that the Purchaser
shall be relying on the foregoing covenant in effecting transactions in securities of the Company. To the extent that the Company delivers
any material, non-public information to the Purchaser without the Purchaser’s consent, the Company hereby covenants and agrees that
the Purchaser shall not have any duty of confidentiality to the Company, any of its subsidiaries, or any of their respective officers,
directors, agents, employees or Affiliates, or a duty to the Company, any of its subsidiaries or any of their respective officers, directors,
agents, employees or Affiliates not to trade on the basis of, such material, non-public information, provided that the Purchaser shall
remain subject to applicable law. To the extent that any notice provided pursuant to any Transaction Document constitutes, or contains,
material, non-public information regarding the Company or any subsidiaries, the Company shall simultaneously file such notice with the
Commission pursuant to a Current Report on Form 8-K. The Company understands and confirms that the Purchaser shall be relying on the foregoing
covenant in effecting transactions in securities of the Company.

directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent
role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls the
Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers,
shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding
such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses,
including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation
that any such Purchaser Party may suffer or incur as a result of or relating to (a) any material breach of any of the
representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or
(b) any action instituted against the Purchaser Parties, or any of them or their respective Affiliates, by any stockholder of the
Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction
Documents (unless such action is solely based upon a material breach of such Purchaser Party’s representations, warranties or
covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such
stockholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party
which is finally judicially determined to constitute fraud, gross negligence or willful misconduct). If any action shall be brought
against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall
promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own
choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such
Purchaser Party except to the extent that (x) the employment thereof has been specifically authorized by the Company in writing, (y)
the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (z) in such action there
is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the
position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more
than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (1) for any settlement by
a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed;
or (2) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s
breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the
other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements
contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others
and any liabilities the Company may be subject to pursuant to law.

Stock on the Trading Market on which it is currently listed, and concurrently with the Closing, the Company shall apply to list or
quote all of the Shares and Warrant Shares on such Trading Market and promptly secure the listing of all of the Shares and Warrant
Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other
Trading Market, it will then include in such application all of the Shares and Warrant Shares, and will take such other action as is
necessary to cause all of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible.
The Company will then take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading
Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of
the Trading Market. The Company agrees to maintain the eligibility of the Common Stock for electronic transfer through the
Depository Trust Company or another established clearing corporation, including, without limitation, by timely payment of fees to

Notwithstanding the foregoing, this Section 4.12 shall not apply in respect of an Exempt Issuance, except that no Variable Rate

stock split or reclassification of the Common Stock without the prior written consent of the Purchaser, provided that no such consent
shall be required for a reverse stock split that is being implemented to satisfy applicable Nasdaq Stock Market listing requirements.

 

4.16         
Exercise Procedures. The form of Notice of Exercise included in the Pre-Funded Warrants set forth the totality of the procedures
required of the Purchaser in order to exercise the Pre-Funded Warrants. No additional legal opinion, other information or instructions
shall be required of the Purchaser to exercise its Pre-Funded Warrants. Without limiting the preceding sentences, no ink-original Notice
of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise
form be required in order to exercise the Pre-Funded Warrants. The Company shall honor exercises of the Pre-Funded Warrants and shall

Document and the Company does not timely perform its related obligations within the periods therein provided, then the Purchaser may rescind
or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole
or in part without prejudice to its future actions and rights; provided, however, that in the case of a rescission of an exercise of a

remedy at law would be adequate.

under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action),

or other amounts are due and payable shall have been canceled.

succeeding Business Day.

Construction. The parties agree that each of them and/or their respective counsel have reviewed and had an opportunity to
revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved
against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition,
each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the
date of this Agreement.

 

5.20         
WAIVER OF JURY TRIAL.  IN ANY ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER

REPRESENTATIONS AND WARRANTIES

Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens imposed by the Company
other than restrictions on transfer provided for in the Transaction Documents. The Warrant Shares, when issued in accordance with the
terms of the Transaction Documents, will be validly issued, fully paid and nonassessable, free and clear of all Liens imposed by the

capital stock the maximum number of shares of Common Stock issuable pursuant to this Agreement and the Warrants.

Transaction Documents. Except as a result of the purchase and sale of the Securities hereunder and under the RD Offering, as well as
the offering and sale of $7,500,000 shares of Series X Convertible Preferred Stock to DaVita, Inc., there are no outstanding

shares of Common Stock or the capital stock of any Subsidiary, or contracts, commitments, understandings or arrangements by which
the Company or any Subsidiary is or may become bound to issue additional shares of Common Stock or Common Stock Equivalents or
capital stock of any Subsidiary. The issuance and sale of the Securities will not obligate the Company or any Subsidiary to issue
shares of Common Stock or other securities to any Person (other than the Purchasers). There are no outstanding securities or
instruments of the Company or any Subsidiary with any provision that adjusts the exercise, conversion, exchange or reset price of
such security or instrument upon an issuance of securities by the Company or any Subsidiary. Except the Series X Convertible

similar provisions, and there are no contracts, commitments, understandings or arrangements by which the Company or any Subsidiary
is or may become bound to redeem a security of the Company or such Subsidiary. The Company does not have any stock appreciation
rights or “phantom stock” plans or agreements or any similar plan or agreement. All of the outstanding shares of capital
stock of the Company are duly authorized, validly issued, fully paid and nonassessable, have been issued in compliance with all
federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar
rights to subscribe for or purchase securities. No further approval or authorization of any stockholder, the Board of Directors or
others is required for the issuance and sale of the Securities. There are no stockholders agreements, voting agreements or other
similar agreements with respect to the Company’s capital stock to which the Company is a party or, to the knowledge of the
Company, between or among any of the Company’s stockholders.

(the foregoing materials, including the exhibits thereto and documents incorporated by reference therein, being collectively referred
to herein as the “SEC Reports”) on a timely basis or has received a valid extension of such time of filing and has
filed any such SEC Reports prior to the expiration of any such extension. As of their respective dates, the SEC Reports complied in all
material respects with the requirements of the Securities Act and the Exchange Act, as applicable, and none of the SEC Reports, when

thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with United States generally accepted
accounting principles applied on a consistent basis during the periods involved (“GAAP”), except as may be otherwise
specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes
required by GAAP, and fairly present in all material respects the financial position of the Company and its consolidated Subsidiaries
as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited

confidential treatment of information. Except for the issuance of the Securities contemplated by this Agreement no event, liability,
fact, circumstance, occurrence or development has occurred or exists or is reasonably expected to occur or exist with respect to the
Company or its Subsidiaries or their respective businesses, prospects, properties, operations, assets or financial condition that
would be required to be disclosed by the Company under applicable securities laws at the time this representation is made or deemed
made that has not been publicly disclosed at least 1 Trading Day prior to the date that this representation is made.

nor any Subsidiary, nor any director or officer thereof, is or has been the subject of any Action involving a claim of violation of or
liability under federal or state securities laws or a claim of breach of fiduciary duty. There has not been, and to the knowledge of
the Company, there is not pending or contemplated, any investigation by the Commission involving the Company or any current or former
director or officer of the Company. The Commission has not issued any stop order or other order suspending the effectiveness of any registration
statement filed by the Company or any Subsidiary under the Exchange Act or the Securities Act.

 

(k)              
Labor Relations. No labor dispute exists or, to the knowledge of the Company, is imminent with respect to any of the employees
of the Company, which could reasonably be expected to result in a Material Adverse Effect. None of the Company’s or its Subsidiaries’
employees is a member of a union that relates to such employee’s relationship with the Company or such Subsidiary, and neither
the Company nor any of its Subsidiaries is a party to a collective bargaining agreement, and the Company and its Subsidiaries believe
that their relationships with their employees are good. To the knowledge of the Company, no executive officer of the Company or any Subsidiary
is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary
information agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of any third
party, and the continued employment of each such executive officer does not subject the Company or any of its Subsidiaries to any liability
with respect to any of the foregoing matters. The Company and its Subsidiaries are in compliance with all U.S. federal, state, local
and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours,
except where the failure to be in compliance could not, individually or in the aggregate, reasonably be expected to have a Material Adverse
Effect.

 

(l)                 Compliance.
Neither the Company nor any Subsidiary: (i) is in default under or in violation of (and no event has occurred that has not been
waived that, with notice or lapse of time or both, would result in a default by the Company or any Subsidiary under), nor has the
Company or any Subsidiary received notice of a claim that it is in default under or that it is in violation of, any indenture, loan
or credit agreement or any other agreement or instrument to which it is a party or by which it or any of its properties is bound
(whether or not such default or violation has been waived), (ii) is in violation of any judgment, decree, or order of any court,
arbitrator or other governmental authority or (iii) is or has been in violation of any statute, rule, ordinance or regulation of any
governmental authority, including without limitation all foreign, federal, state and local laws relating to taxes, environmental
protection, occupational health and safety, product quality and safety and employment and labor matters, except in each case as
could not have or reasonably be expected to result in a Material Adverse Effect.

 

    13

     

    

 

(m)            
 Environmental Laws. The Company and its Subsidiaries (i) are in compliance with all federal, state, local and foreign laws
relating to pollution or protection of human health or the environment (including ambient air, surface water, groundwater, land surface
or subsurface strata), including laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants,
or toxic or hazardous substances or wastes (collectively, “Hazardous Materials”) into the environment, or otherwise
relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials,
as well as all authorizations, codes, decrees, demands, or demand letters, injunctions, judgments, licenses, notices or notice letters,
orders, permits, plans or regulations, issued, entered, promulgated or approved thereunder (“Environmental Laws”);

businesses; and (iii) are in compliance with all terms and conditions of any such permit, license or approval where in each clause (i),
(ii) and (iii), the failure to so comply could be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect.

 

(n)              
Regulatory Permits. The Company and the Subsidiaries possess all certificates, authorizations and permits issued by the
appropriate federal, state, local or foreign regulatory authorities necessary to conduct their respective businesses as described in
the SEC Reports, except where the failure to possess such permits could not reasonably be expected to result in a Material Adverse Effect
(“Material Permits”), and neither the Company nor any Subsidiary has received any notice of proceedings relating to
the revocation or modification of any Material Permit.

 

(o)               Title
to Assets. The Company and the Subsidiaries have good and marketable title in fee simple to all real property owned by them and
good and marketable title in all personal property owned by them that is material to the business of the Company and the
Subsidiaries, in each case free and clear of all Liens, except for (i) Liens as do not materially affect the value of such property
and do not materially interfere with the use made and proposed to be made of such property by the Company and the Subsidiaries, and
(ii) Liens for the payment of federal, state or other taxes, for which appropriate reserves have been made therefor in accordance
with GAAP and the payment of which is neither delinquent nor subject to penalties. Any real property and facilities held under lease
by the Company and the Subsidiaries are held by them under valid, subsisting and enforceable leases with which the Company and the
Subsidiaries are in compliance.

 

    14

     

    

 

(p)              
Intellectual Property. The Company and the Subsidiaries have, or have rights to use, all patents, patent applications,
trademarks, trademark applications, service marks, trade names, trade secrets, inventions, copyrights, licenses and other intellectual
property rights and similar rights necessary or required for use in connection with their respective businesses as described in the SEC
Reports and which the failure to so have could have a Material Adverse Effect (collectively, the “Intellectual Property Rights”).
None of, and neither the Company nor any Subsidiary has received a notice (written or otherwise) that any of, the Intellectual Property
Rights has expired, terminated or been abandoned, or is expected to expire or terminate or be abandoned, within two (2) years from the
date of this Agreement. Neither the Company nor any Subsidiary has received, since the date of the latest audited financial statements
included within the SEC Reports, a written notice of a claim or otherwise has any knowledge that the Intellectual Property Rights violate
or infringe upon the rights of any Person, except as could not have or reasonably be expected to not have a Material Adverse Effect.
To the knowledge of the Company, all such Intellectual Property Rights are enforceable and there is no existing infringement by another
Person of any of the Intellectual Property Rights. The Company and its Subsidiaries have taken reasonable security measures to protect
the secrecy, confidentiality and value of all of their intellectual properties, except where failure to do so could not, individually
or in the aggregate, reasonably be expected to have a Material Adverse Effect.

 

(q)              
Insurance. The Company and the Subsidiaries are insured by insurers of recognized financial responsibility against such
losses and risks and in such amounts as are prudent and customary in the businesses in which the Company and the Subsidiaries are engaged,
including, but not limited to, directors and officers insurance coverage at least equal to the aggregate Subscription Amount. Neither
the Company nor any Subsidiary has any reason to believe that it will not be able to renew its existing insurance coverage as and when
such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a significant
increase in cost.

 

(r)                Transactions
with Affiliates and Employees. None of the officers or directors of the Company or any Subsidiary and, to the knowledge of the
Company, none of the employees of the Company or any Subsidiary is presently a party to any transaction with the Company or any

providing for the furnishing of services to or by, providing for rental of real or personal property to or from, providing for the
borrowing of money from or lending of money to or otherwise requiring payments to or from any officer, director or such employee or,
to the knowledge of the Company, any entity in which any officer, director, or any such employee has a substantial interest or is an
officer, director, trustee, stockholder, member or partner, in each case in excess of $120,000 other than for (i) payment of salary
or consulting fees for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company and (iii) other employee
benefits, including stock option agreements under any stock option plan of the Company.

 

    15

     

    

 

(s)               
Sarbanes-Oxley; Internal Accounting Controls. The Company and the Subsidiaries are in compliance with any and all applicable
requirements of the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and any and all applicable rules and regulations
promulgated by the Commission thereunder that are effective as of the date hereof and as of the Closing Date. The Company and the Subsidiaries
maintain a system of internal accounting controls sufficient to provide reasonable assurance that: (i) transactions are executed in accordance
with management’s general or specific authorizations, (ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with GAAP and to maintain asset accountability, (iii) access to assets is permitted only in accordance with
management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets
at reasonable intervals and appropriate action is taken with respect to any differences. The Company and the Subsidiaries have established
disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and the Subsidiaries and
designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it
files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s
rules and forms. The Company’s certifying officers have evaluated the effectiveness of the disclosure controls and procedures of
the Company and the Subsidiaries as of the end of the period covered by the most recently filed periodic report under the Exchange Act
(such date, the “Evaluation Date”). The Company presented in its most recently filed periodic report under the Exchange
Act the conclusions of the certifying officers about the effectiveness of the disclosure controls and procedures based on their evaluations
as of the Evaluation Date. Since the Evaluation Date, there have been no changes in the internal control over financial reporting (as
such term is defined in the Exchange Act) of the Company and its Subsidiaries that have materially affected, or is reasonably likely
to materially affect, the internal control over financial reporting of the Company and its Subsidiaries.

 

(t)                
Certain Fees. No brokerage or finder’s fees or commissions are or will be payable by the Company or any Subsidiary
to any broker, financial advisor or consultant, finder, placement agent, investment banker, bank or other Person with respect to the
transactions contemplated by the Transaction Documents. The Purchasers shall have no obligation with respect to any fees or with respect
to any claims made by or on behalf of other Persons for fees of a type contemplated in this Section that may be due in connection with
the transactions contemplated by the Transaction Documents.

 

(u)              
Private Placement. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section 3.2,
no registration under the Securities Act is required for the offer and sale of the Securities by the Company to the Purchasers as contemplated
hereby. The issuance and sale of the Securities hereunder does not contravene the rules and regulations of the Trading Market.

 

    16

     

    

 

(v)              
 Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Securities,
will not be or be an Affiliate of, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.
The Company shall conduct its business in a manner so that it will not become an “investment company” subject to registration
under the Investment Company Act of 1940, as amended.

 

(w)            
Registration Rights. Other than each of the Purchasers, no Person has any right to cause the Company or any Subsidiary
to effect the registration under the Securities Act of any securities of the Company or any Subsidiary.

 

(x)              
Listing and Maintenance Requirements. The Common Stock is registered pursuant to Section 12(b) or 12(g) of the Exchange
Act, and the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration
of the Common Stock under the Exchange Act nor has the Company received any notification that the Commission is contemplating terminating
such registration. The Company has not, in the 12 months preceding the date hereof, received notice from any Trading Market on which
the Common Stock is or has been listed or quoted to the effect that the Company is not in compliance with the listing or maintenance
requirements of such Trading Market. The Company is, and has no reason to believe that it will not in the foreseeable future continue
to be, in compliance with all such listing and maintenance requirements. The Common Stock is currently eligible for electronic transfer
through the Depository Trust Company or another established clearing corporation and the Company is current in payment of the fees to
the Depository Trust Company (or such other established clearing corporation) in connection with such electronic transfer.

 

(y)              
Application of Takeover Protections. The Company and the Board of Directors have taken all necessary action, if any, in
order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights
agreement) or other similar anti-takeover provision under the Company’s certificate of incorporation (or similar charter documents)
or the laws of its state of incorporation that is or could become applicable to the Purchasers as a result of the Purchasers and the
Company fulfilling their obligations or exercising their rights under the Transaction Documents, including without limitation as a result
of the Company’s issuance of the Securities and the Purchasers’ ownership of the Securities up to a Beneficial Ownership
level of 9.99%.

 

(z)               Disclosure.
Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company
confirms that neither it nor any other Person acting on its behalf has provided any of the Purchasers or their agents or counsel
with any information that it believes constitutes or might constitute material, non-public information. The Company understands and
confirms that the Purchasers will rely on the foregoing representation in effecting transactions in securities of the Company. All
of the disclosure furnished by or on behalf of the Company to the Purchasers regarding the Company and its Subsidiaries, their
respective businesses and the transactions contemplated hereby, including the Disclosure Schedules to this Agreement, is true and
correct and does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make
the statements made therein, in the light of the circumstances under which they were made, not misleading. The press releases
disseminated by the Company during the twelve months preceding the date of this Agreement taken as a whole do not contain any untrue
statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the
statements therein, in the light of the circumstances under which they were made and when made, not misleading. The Company
acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the transactions
contemplated hereby other than those specifically set forth in Section 3.2 hereof.

 

    17

     

    

 

(aa)           
No Integrated Offering. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Section
3.2, neither the Company, nor any of its Affiliates, nor any Person acting on its or their behalf has, directly or indirectly, made any
offers or sales of any security or solicited any offers to buy any security, under circumstances that would cause this offering of the
Securities to be integrated with prior offerings by the Company for purposes of (i) the Securities Act which would require the registration
of any such securities under the Securities Act, or (ii) any applicable shareholder approval provisions of any Trading Market on which
any of the securities of the Company are listed or designated.

 

(bb)           Solvency.
Based on the consolidated financial condition of the Company as of the Closing Date, after giving effect to the receipt by the
Company of the proceeds from the sale of the Securities hereunder, the receipt of the proceeds from the RD Offering, and the
offering and sale of $7,500,000 shares of Series X Convertible Preferred Stock to DaVita, Inc., (i) the fair saleable value of the
Company’s assets exceeds the amount that will be required to be paid on or in respect of the Company’s existing debts
and other liabilities (including known contingent liabilities) as they mature, (ii) the Company’s assets do not constitute
unreasonably small capital to carry on its business as now conducted and as proposed to be conducted including its capital needs
taking into account the particular capital requirements of the business conducted by the Company, consolidated and projected capital
requirements and capital availability thereof, and (iii) the current cash flow of the Company, together with the proceeds the
Company would receive, were it to liquidate all of its assets, after taking into account all anticipated uses of the cash, would be
sufficient to pay all amounts on or in respect of its liabilities when such amounts are required to be paid. The Company does not
intend to incur debts beyond its ability to pay such debts as they mature (taking into account the timing and amounts of cash to be
payable on or in respect of its debt). The Company has no knowledge of any facts or circumstances which lead it to believe that it
will file for reorganization or liquidation under the bankruptcy or reorganization laws of any jurisdiction within one year from the
Closing Date. The SEC Reports set forth as of the date hereof all outstanding secured and unsecured Indebtedness of the
Company or any Subsidiary, or for which the Company or any Subsidiary has commitments. For the purposes of this Agreement,
 “Indebtedness” means (x) any liabilities for borrowed money or amounts owed in excess of $50,000 (other than
trade accounts payable incurred in the ordinary course of business), (y) all guaranties, endorsements and other contingent
obligations in respect of indebtedness of others, whether or not the same are or should be reflected in the Company’s
consolidated balance sheet (or the notes thereto), except guaranties by endorsement of negotiable instruments for deposit or
collection or similar transactions in the ordinary course of business; and (z) the present value of any lease payments in excess of
$50,000 due under leases required to be capitalized in accordance with GAAP. Neither the Company nor any Subsidiary is in default
with respect to any Indebtedness.

 

    18

     

    

 

(cc)           
Tax Status. Except for matters that would not, individually or in the aggregate, have or reasonably be expected to result
in a Material Adverse Effect, the Company and its Subsidiaries each (i) has made or filed all United States federal, state and local
income and all foreign income and franchise tax returns, reports and declarations required by any jurisdiction to which it is subject,
(ii) has paid all taxes and other governmental assessments and charges that are material in amount, shown or determined to be due on
such returns, reports and declarations and (iii) has set aside on its books provision reasonably adequate for the payment of all material
taxes for periods subsequent to the periods to which such returns, reports or declarations apply. There are no unpaid taxes in any material
amount claimed to be due by the taxing authority of any jurisdiction, and the officers of the Company or of any Subsidiary know of no
basis for any such claim.

 

(dd)          
No General Solicitation. Neither the Company nor any Person acting on behalf of the Company has offered or sold any of
the Securities by any form of general solicitation or general advertising. The Company has offered the Securities for sale only to the
Purchasers and certain other “accredited investors” within the meaning of Rule 501 under the Securities Act.

 

(ee)           
Foreign Corrupt Practices. Neither the Company nor any Subsidiary, nor to the knowledge of the Company or any Subsidiary,
any agent or other person acting on behalf of the Company or any Subsidiary, has (i) directly or indirectly, used any funds for unlawful
contributions, gifts, entertainment or other unlawful expenses related to foreign or domestic political activity, (ii) made any unlawful
payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or campaigns from corporate
funds, (iii) failed to disclose fully any contribution made by the Company or any Subsidiary (or made by any person acting on its behalf
of which the Company is aware) which is in violation of law or (iv) violated in any material respect any provision of FCPA.

partnership, limited liability company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to
which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof,

application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited
by applicable law.

under the Securities Act or any applicable state securities law and is acquiring the Securities as principal for its own account and
not with a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable
state securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable
state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the

not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise in compliance with
applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business.

 

(c)              
Purchaser Status. At the time such Purchaser was offered the Securities, it was, and as of the date hereof it is, and on
each date on which it exercises any Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1),
(a)(2), (a)(3), (a)(7), (a)(8), (a)(9), (a)(12), or (a)(13) under the Securities Act or (ii) a “qualified institutional buyer”
as defined in Rule 144A(a) under the Securities Act.

 

(d)              
Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge, sophistication
and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment

(e)              
General Solicitation. Such Purchaser is not, to such Purchaser’s knowledge, purchasing the Securities as a result

media or broadcast over television or radio or presented at any seminar or, to the knowledge of such Purchaser, any other general solicitation
or general advertisement.

 

(f)               
Access to Information. Such Purchaser acknowledges that it has had the opportunity to review the Transaction Documents
(including all exhibits and schedules thereto) and the SEC Reports and has been afforded (i) the opportunity to ask such questions as
it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering
of the Securities and the merits and risks of investing in the Securities; (ii) access to information about the Company and its financial
condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment;
and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort

such Purchaser first received a term sheet (written or oral) from the Company or any other Person representing the Company setting forth
the material terms of the transactions contemplated hereunder and ending immediately prior to the execution hereof. Notwithstanding the
foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate
portions of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the
portfolio managers managing other portions of such Purchaser’s assets, the representation set forth above shall only apply with
respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered
by this Agreement. Other than to other Persons party to this Agreement or to such Purchaser’s representatives, including, without
limitation, its officers, directors, partners, legal and other advisors, employees, agents and Affiliates, such Purchaser has maintained
the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction).
Notwithstanding the foregoing, for the avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or

contained in any other Transaction Document or any other document or instrument executed and/or delivered in connection with this
Agreement or the consummation of the transactions contemplated hereby. Notwithstanding the foregoing, for the avoidance of doubt,

ARTICLE IV.

OTHER AGREEMENTS OF THE PARTIES

 

4.1             
Transfer Restrictions.

 

(a)              
The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of
Securities other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser or
in connection with a pledge as contemplated in Section 4.1(b), the Company may require the transferor thereof to provide to the Company
an opinion of counsel selected by the transferor and reasonably acceptable to the Company, the form and substance of which opinion shall
be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities
under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement
and the Registration Rights Agreement and shall have the rights and obligations of a Purchaser under this Agreement and the Registration
Rights Agreement.

 

(b)              
The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Securities in the
following form:

 

THIS SECURITY HAS NOT BEEN REGISTERED
WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT
PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION
NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS SECURITY
MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION
THAT IS AN “ACCREDITED INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES.

 

    25

     

    

 

The Company
acknowledges and agrees that a Purchaser may from time to time pledge pursuant to a bona fide margin agreement with a registered
broker-dealer or grant a security interest in some or all of the Securities to a financial institution that is an “accredited
investor” as defined in Rule 501(a) under the Securities Act and, if required under the terms of such arrangement, such
Purchaser may transfer pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be
subject to approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required
in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the
Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in
connection with a pledge or transfer of the Securities, including, if the Securities are subject to registration pursuant to the
Registration Rights Agreement, the preparation and filing of any required prospectus supplement under Rule 424(b)(3) under the
Securities Act or other applicable provision of the Securities Act to appropriately amend the list of Selling Stockholders (as
defined in the Registration Rights Agreement) thereunder.

 

(c)               Certificates
evidencing the Shares and Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof), (i)
while a registration statement (including the Registration Statement) covering the resale of such security is effective under the
Securities Act (subject to receipt of an undertaking from the Purchaser(s) that sales of the securities that are so registered will
only be made in accordance with Rule 144 or pursuant to the Registration Statement), (ii) following any sale of such Shares or
Warrant Shares pursuant to Rule 144 (assuming cashless exercise of the Warrants), (iii) if such Shares or Warrant Shares are
eligible for sale under Rule 144 (assuming cashless exercise of the Warrants), or (iv) if such legend is not required under
applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the
Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent or the Purchaser if required by the
Transfer Agent to effect the removal of the legend hereunder, or if requested by a Purchaser, respectively. If all or any portion of
a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if
such Shares or Warrant Shares may be sold under Rule 144 and the Company is then in compliance with the current public information
required under Rule 144 (assuming cashless exercise of the Warrants), or if the Shares or Warrant Shares may be sold under Rule 144
without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such
Shares or Warrant Shares or if such legend is not otherwise required under applicable requirements of the Securities Act (including
judicial interpretations and pronouncements issued by the staff of the Commission) then such Warrant Shares shall be issued free of
all legends. The Company agrees that at such time as such legend is no longer required under this Section 4.1(c), it will, within
two (2) Trading Days following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Shares
or Warrant Shares, as the case may be, issued with a restrictive legend, along with such other reasonable and customary
documentation (e.g., Rule 144 representation letters) as may be requested by the Company, its counsel or the Company’s
transfer agent (such date, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser a
certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on
its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4.
Certificates for Securities subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by
crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such
Purchaser.

 

    26

     

    

 

(d)              
In addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, (i) as partial
liquidated damages and not as a penalty, for each $1,000 of Shares or Warrant Shares (based on the VWAP of the Common Stock on the date
such Securities are submitted to the Transfer Agent) delivered for removal of the restrictive legend and subject to Section 4.1(c), $10
per Trading Day (increasing to $20 per Trading Day five (5) Trading Days after such damages have begun to accrue) for each Trading Day
after the Legend Removal Date until such certificate is delivered without a legend and (ii) if the Company fails to (a) issue and deliver
(or cause to be delivered) to a Purchaser by the Legend Removal Date a certificate representing the Securities so delivered to the Company
by such Purchaser that is free from all restrictive and other legends and (b) if after the Legend Removal Date the Purchaser is required
by its broker to purchase (in an open market transaction or otherwise) or the Purchaser’s brokerage firm otherwise purchases, shares
of Common Stock to deliver in satisfaction of a sale by the Purchaser of the un-legended Common Stock that the Purchaser anticipated
receiving on the Legend Removal Date (a “Buy-In”), then the Company shall pay in cash to the Purchaser the amount, if any,
by which (x) the Purchaser’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased
exceeds (y) the amount obtained by multiplying (1) the number of shares of Common Stock that the Company was required to deliver to the
Purchaser on the Legend Removal Date at issue times (2) the price at which the sell order giving rise to such purchase obligation was
executed. The Purchaser shall provide the Company written notice indicating the amounts payable to the Purchaser in respect of the Buy-In
and, upon request of the Company, evidence of the amount of such loss.

 

(e)              
Each Purchaser, severally and not jointly with the other Purchasers, agrees with the Company that such Purchaser will sell any
Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements,
or an exemption therefrom, and that if Securities are sold pursuant to a Registration Statement, they will be sold in compliance with
the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates representing
Securities as set forth in this Section 4.1 is predicated upon the Company’s reliance upon this understanding.

 

4.2             
Furnishing of Information; Public Information.

 

(a)              
Until the earlier of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to
maintain the registration of the Common Stock under Section 12(b) or 12(g) of the Exchange Act and to timely file (or obtain extensions
in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof
pursuant to the Exchange Act even if the Company is not then subject to the reporting requirements of the Exchange Act.

security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner
that would require the registration under the Securities Act of the sale of the Securities or that would be integrated with the offer
or sale of the Securities for purposes of the rules and regulations of any Trading Market such that it would require shareholder approval
prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction.

of the Purchasers by the Company or any of its Subsidiaries, or any of their respective officers, directors, employees or agents in connection
with the transactions contemplated by the Transaction Documents. In addition, effective upon the issuance of such press release, the
Company acknowledges and agrees that any and all confidentiality or similar obligations under any agreement, whether written or oral,

hand, and any of the Purchasers or any of their Affiliates on the other hand, shall terminate. The Company and each Purchaser shall consult
with each other in issuing any other press releases with respect to the transactions contemplated hereby, and neither the Company nor
any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company,
with respect to any press release of any Purchaser, or without the prior consent of each Purchaser, with respect to any press release
of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law, in which case
the disclosing party shall promptly provide the other party with prior notice of such public statement or communication. Notwithstanding
the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing

the filing of final Transaction Documents with the Commission and (b) to the extent such disclosure is required by law or Trading Market
regulations, in which case the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause
(b).

 

4.5             
Shareholder Rights Plan. No claim will be made or enforced by the Company or, with the consent of the Company, any other
Person, that any Purchaser is an “Acquiring Person” under any control share acquisition, business combination, poison
pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted
by the Company, or that any Purchaser could be deemed to trigger the provisions of any such plan or arrangement, by virtue of receiving
Securities under the Transaction Documents or under any other agreement between the Company and the Purchasers.

 

    28

4.8              Indemnification
of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and its
directors, officers, shareholders, members, partners, employees and agents (and any other Persons with a functionally equivalent
role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such
Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers,
shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding
such titles notwithstanding a lack of such title or any other title) of such controlling persons (each, a “Purchaser
Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses,
including all judgments, amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation
that any such Purchaser Party may suffer or incur as a result of or relating to (a) any material breach of any of the
representations, warranties, covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or
(b) any action instituted against the Purchaser Parties, or any of them or their respective Affiliates, by any stockholder of the
Company who is not an Affiliate of such Purchaser Party, with respect to any of the transactions contemplated by the Transaction
Documents (unless such action is solely based upon a material breach of such Purchaser Party’s representations, warranties or
covenants under the Transaction Documents or any agreements or understandings such Purchaser Party may have with any such
stockholder or any violations by such Purchaser Party of state or federal securities laws or any conduct by such Purchaser Party
which is finally judicially determined to constitute fraud, gross negligence or willful misconduct). If any action shall be brought
against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall
promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own
choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any
such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such
Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in writing,
(ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action
there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and
the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more
than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by
a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed;
or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s
breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the
other Transaction Documents. The indemnification required by this Section 4.8 shall be made by periodic payments of the amount
thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements
contained herein shall be in addition to any cause of action or similar right of any Purchaser Party against the Company or others
and any liabilities the Company may be subject to pursuant to law.

4.9             
Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve
and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling
the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the Warrants.

 

4.10          Listing
of Common Stock. The Company hereby agrees to use reasonable best efforts to maintain the listing or quotation of the Common
Stock on the Trading Market on which it is currently listed, and concurrently with the Closing, the Company shall apply to list or
quote all of the Shares and Warrant Shares on such Trading Market and promptly secure the listing of all of the Shares and Warrant
Shares on such Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other
Trading Market, it will then include in such application all of the Shares and Warrant Shares, and will take such other action as is
necessary to cause all of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible.
The Company will then take all action reasonably necessary to continue the listing and trading of its Common Stock on a Trading
Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of
the Trading Market. The Company agrees to maintain the eligibility of the Common Stock for electronic transfer through the
Depository Trust Company or another established clearing corporation, including, without limitation, by timely payment of fees to
the Depository Trust Company or such other established clearing corporation in connection with such electronic transfer.

4.11         
Subsequent Equity Sales.

 

(a)              
From the date hereof until ninety (90) days after the Effective Date, neither the Company nor any Subsidiary shall (i) issue,
enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common Stock Equivalents,
but excluding (x) the issuance of up to 7,500 shares of Series X Convertible Preferred Stock to DaVita, Inc., and (y) the offering and
sale of up to $12 million of securities to the Purchaser(s) in a concurrent offering; or (ii) file any registration statement or any
amendment or supplement thereto, in each case other than as contemplated pursuant to the Registration Rights Agreement

 

(b)              
From the date hereof until the one-year anniversary of the Effective Date, the Company shall be prohibited from effecting or entering
into an agreement to effect any issuance by the Company or any of its Subsidiaries of Common Stock or Common Stock Equivalents (or a
combination of units thereof) involving a Variable Rate Transaction. “Variable Rate Transaction” means a transaction
in which the Company (i) issues or sells any debt or equity securities that are convertible into, exchangeable or exercisable for, or
include the right to receive, additional shares of Common Stock either (A) at a conversion price, exercise price or exchange rate or
other price that is based upon, and/or varies with, the trading prices of or quotations for the shares of Common Stock at any time after
the initial issuance of such debt or equity securities or (B) with a conversion, exercise or exchange price that is subject to being
reset at some future date after the initial issuance of such debt or equity security or upon the occurrence of specified or contingent
events directly or indirectly related to the business of the Company or the market for the Common Stock or (ii) enters into, or effects
a transaction under, any agreement, including, but not limited to, an equity line of credit, whereby the Company may issue securities
at a future determined price. Any Purchaser shall be entitled to obtain injunctive relief against the Company to preclude any such issuance,
which remedy shall be in addition to any right to collect damages.

 

(c)              
Notwithstanding the foregoing, this Section 4.11 shall not apply in respect of an Exempt Issuance, except that no Variable Rate
Transaction shall be an Exempt Issuance, and provided, further, that the Company shall be permitted to make offerings and sales of Common
Stock under an at-the-market offering facility commencing January 1, 2023.

 

4.12         
[reserved]

 

    31

     

    

 

4.13          Certain
Transactions and Confidentiality. Each Purchaser, severally and not jointly with the other Purchasers, covenants that neither
it, nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including
Short Sales, of any of the Company’s securities during the period commencing with the execution of this Agreement and ending
at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press
release as described in Section 4.4.  Each Purchaser, severally and not jointly with the other Purchasers, covenants that
until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial
press release as described in Section 4.4, such Purchaser will maintain the confidentiality of the existence and terms of this
transaction and the information included in the Disclosure Schedules.  Notwithstanding the foregoing and notwithstanding
anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any
representation, warranty or covenant hereby that it will not engage in effecting transactions in any securities of the Company after
the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as
described in Section 4.4, (ii) no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of
the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this
Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser
shall have any duty of confidentiality or duty not to trade in the securities of the Company to the Company or its Subsidiaries
after the issuance of the initial press release as described in Section 4.4. 

 

4.14         
Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation
D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably
determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers at the Closing under
applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly
upon request of any Purchaser.

 

4.15         
Acknowledgment of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the
outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges
that its obligations under the Transaction Documents, including, without limitation, its obligation to issue the Shares and Warrant Shares
pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or
reduction, regardless of the effect of any such dilution or any claim the Company may have against any Purchaser and regardless of the
dilutive effect that such issuance may have on the ownership of the other stockholders of the Company.

 

4.16         
Exercise Procedures. The form of Notice of Exercise included in the Warrants set forth the totality of the procedures required
of the Purchasers in order to exercise the Warrants. No additional legal opinion, other information or instructions shall be required
of the Purchasers to exercise their Warrants. Without limiting the preceding sentences, no ink-original Notice of Exercise shall be required,
nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise form be required in order to
exercise the Warrants. The Company shall honor exercises of the Warrants and shall deliver Warrant Shares in accordance with the terms,
conditions and time periods set forth in the Transaction Documents.

 

4.17          Lock-Up
Agreements. The Company shall not amend, modify, waive or terminate any provision of any of the Lock-Up Agreements except to
extend the term of the lock-up period and shall enforce the provisions of each Lock-Up Agreement in accordance with its terms. If
any party to a Lock-Up Agreement breaches any provision of a Lock-Up Agreement, the Company shall promptly use its best efforts to
seek specific performance of the terms of such Lock-Up Agreement.

5.1             
Termination.  This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder
only and without any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice to the other
parties, if the Closing has not been consummated on or before the fifth (5th) Trading Day following the date hereof; provided,
however, that no such termination will affect the right of any party to sue for any breach by any other party (or parties).

 

5.2             
Fees and Expenses. Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the
fees and expenses of its advisers, counsel, accountants and other experts, if any, and all other expenses incurred by such party incident
to the negotiation, preparation, execution, delivery and performance of this Agreement. The Company shall pay all Transfer Agent fees
(including, without limitation, any fees required for same-day processing of any instruction letter delivered by the Company and any
exercise notice delivered by a Purchaser), stamp taxes and other taxes and duties levied in connection with the delivery of any Securities
to the Purchasers.

 

5.3             
Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding
of the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and understandings, oral or written,
with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules.

 

5.4             
Notices. Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall

in the case of an amendment, by the Company and Purchasers which purchased at least 50.1% in interest of the Shares based on the
initial Subscription Amounts hereunder (or, prior to the Closing, the Company and each Purchaser) or, in the case of a waiver, by
the party against whom enforcement of any such waived provision is sought, provided that if any amendment, modification or waiver
disproportionately and adversely impacts a Purchaser (or group of Purchasers), the consent of at least 50.1% in interest (based on
the initial Subscription Amounts hereunder) of such disproportionately impacted Purchaser (or group of Purchasers) shall also be
required. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a
continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement
hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such
right.

 

    33

5.8             
No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors
and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise
set forth in Section 4.8.

 

5.9              Governing
Law. All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be

exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive
jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect
to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Action or
Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action or Proceeding is
improper or is an inconvenient venue for such Proceeding. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such Action or Proceeding by mailing a copy thereof via registered or certified mail or

    34

     

    

 

5.10         
Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Securities.

 

5.11         
Execution. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered
one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party,
it being understood that the parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission
or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party
executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature
page were an original thereof.

 

5.12         
Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction
to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall
remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated
by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would
have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared
invalid, illegal, void or unenforceable.

 

5.13         
Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in (and without limiting any similar
provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction
Document and the Company does not timely perform its related obligations within the periods therein provided, then such Purchaser may
rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election
in whole or in part without prejudice to its future actions and rights; provided, however, that, in the case of a rescission
of an exercise of a Warrant, the applicable Purchaser shall be required to return any shares of Common Stock subject to any such rescinded
exercise notice concurrently with the return to such Purchaser of the aggregate exercise price paid to the Company for such shares and
the restoration of such Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant (including, issuance
of a replacement warrant certificate evidencing such restored right).

 

5.14          Replacement

shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in
lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the
Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also

Securities.

 

    35

     

    

 

5.15         
Remedies. In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of
damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties
agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in
the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such obligation the
defense that a remedy at law would be adequate.

 

5.16         
Payment Set Aside. To the extent that the Company makes a payment or payments to any Purchaser pursuant to any Transaction
Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement

by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law
(including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent
of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force
and effect as if such payment had not been made or such enforcement or setoff had not occurred.

 

5.17

Saturdays, Sundays, Holidays, etc.If the last or appointed day for the taking of any action or the expiration of any
right required or granted herein shall not be a Business Day, then such action may be taken or such right may be exercised on the next

to revise the Transaction Documents and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved
against the drafting party shall not be employed in the interpretation of the Transaction Documents or any amendments thereto. In addition,
each and every reference to share prices and shares of Common Stock in any Transaction Document shall be subject to adjustment for reverse
and forward stock splits, stock dividends, stock combinations and other similar transactions of the Common Stock that occur after the
