 Exhibit 10.1 

FORM OF INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT is made and effective as of [Date of Appointment] 2015 (this “Agreement”) and is
between Accenture Holdings plc (the “Company”), Accenture LLP (the “Indemnitor”), an indirectly wholly-owned subsidiary of the Company, and [Name of Indemnitee] (the
“Indemnitee”). 
 Background 

The Company believes that in order to attract and retain highly competent persons to serve as directors, secretary or in other capacities,
including as employees, agents or other officers of the Company, it must provide such persons with adequate protection through indemnification against the risks of claims and actions against them arising out of or in connection with their services
to and activities on behalf of the Company and its affiliates. 
 The Indemnitee is an employee of the Accenture group. Upon the
cross-border merger of the Company and Accenture SCA, Accenture plc, the publically traded holding company of the Accenture Group, will be the Company’s indirect holding company. 

The Company desires and has requested the Indemnitee to serve as a director, secretary or other officer, employee or agent of the Company and,
in order to induce the Indemnitee to serve as a director, secretary or other officer, employee or agent of the Company, the Indemnitor is willing to grant the Indemnitee the indemnification provided for herein. The Indemnitee is willing to so serve
on the basis that such indemnification be provided. 
 The parties to this Agreement desire to set forth their agreement regarding
indemnification and the advancement of expenses as specified herein. 
 In consideration of the Indemnitee’s service to the Company and
the covenants and agreements set forth below, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows: 

Section 1. Indemnification.  

Subject to the terms and conditions of this Agreement and to the fullest extent permitted by the General Corporation Law of the State of
Delaware (the “ DGCL”), the Indemnitee shall be indemnified out of the funds of the Indemnitor against all liabilities, losses, damages or expenses (including but not limited to liabilities resulting from or in connection
with a settlement or under contract, tort, statute or any applicable foreign law or regulation and all legal and other costs and expenses properly payable) arising out of or in connection with the actual or purported execution or discharge of his
duties or the exercise or purported exercise of his powers or otherwise in relation to or in connection with his duties, powers or office as a director or secretary, or in other capacities, including as an employee, agent or other officer, in each
case relating to or on behalf of the Company or its subsidiaries and affiliates. 
 Section 2. Advance Payment of Expenses.
To the fullest extent permitted by the DGCL, expenses (including reasonable attorneys’ fees) incurred by the Indemnitee in appearing at, participating in or defending any action, suit or proceeding or in connection with an enforcement
action as contemplated by Section 3(e) shall be paid by the Indemnitor in advance of the final disposition of such action, suit or proceeding within 30 days after receipt by the Indemnitor of a statement or statements from the Indemnitee
requesting such advance or advances from time to time. The Indemnitee hereby undertakes to repay any amounts advanced (without interest) to the extent that it is ultimately determined that the Indemnitee is not entitled under this Agreement to be
indemnified by the Indemnitor in respect thereof. No other form of undertaking shall be required of the Indemnitee other than the execution of this Agreement. This Section 2 shall be subject to Section 3(b) and shall not apply to any claim
made by the Indemnitee which is excluded pursuant to Section 6. 

 Section 3. Procedure for Indemnification; Notification and Defense of Claim.

 (a) Promptly after receipt by the Indemnitee of notice of the commencement of any action, suit or proceeding, the Indemnitee shall, if a
claim in respect thereof is to be made against the Indemnitor hereunder, notify the Indemnitor in writing of the commencement thereof. The failure to promptly notify the Indemnitor of the commencement of the action, suit or proceeding, or of the
Indemnitee’s request for indemnification, will not relieve the Indemnitor from any liability that it may have to the Indemnitee hereunder, except to the extent the Indemnitor is actually and materially prejudiced in its defense of such action,
suit or proceeding as a result of such failure. To obtain indemnification under this Agreement, the Indemnitee shall submit to the Indemnitor a written request therefor including such documentation and information as is reasonably available to the
Indemnitee and is reasonably necessary to enable the Indemnitor to determine whether and to what extent the Indemnitee is entitled to indemnification. 

(b) With respect to any action, suit or proceeding of which the Indemnitor is so notified as provided in this Agreement, the Indemnitor shall,
subject to the last two sentences of this Section 3(b), be entitled to assume the defense of such action, suit or proceeding, with counsel reasonably acceptable to the Indemnitee, upon the delivery to the Indemnitee of written notice of its
election to do so. After delivery of such notice, approval of such counsel by the Indemnitee and the retention of such counsel by the Indemnitor, the Indemnitor will not be liable to the Indemnitee under this Agreement for any subsequently-incurred
fees of separate counsel engaged by the Indemnitee with respect to the same action, suit or proceeding unless the employment of separate counsel by the Indemnitee has been previously authorized in writing by the Indemnitor. Notwithstanding the
foregoing, if the Indemnitee, based on the advice of his or her counsel, shall have reasonably concluded (with written notice being given to the Indemnitor setting forth the basis for such conclusion) that, in the conduct of any such defense, there
is or is reasonably likely to be a conflict of interest or position with respect to a significant issue between (i) the Indemnitor or the Company and (ii) the Indemnitee, then the Indemnitor will not be entitled, without the written
consent of the Indemnitee, to assume such defense. In addition, the Indemnitor will not be entitled, without the written consent of the Indemnitee, to assume the defense of any claim brought by or in the right of the Indemnitor or the Company. 

(c) Subject to the terms and conditions of this Agreement and to the fullest extent permitted by the DGCL, the Indemnitor’s assumption of
the defense of an action, suit or proceeding in accordance with Section 3(b) will constitute an irrevocable acknowledgement by the Indemnitor that any loss and liability suffered by the Indemnitee and expenses (including reasonable
attorneys’ fees), judgments, fines and amounts paid in settlement by or for the account of the Indemnitee incurred in connection therewith are indemnifiable by the Indemnitor under Section 1. 

(d) The determination whether to grant the Indemnitee’s indemnification request shall be made promptly and in any event within 30 days
following the Indemnitor’s receipt of a request for indemnification in accordance with Section 3(a). If the Indemnitor determines that the Indemnitee is entitled to such indemnification or, as contemplated by paragraph 3(c) the Indemnitor
has acknowledged such entitlement, the Indemnitor will make payment to the Indemnitee of the indemnifiable amount within such 30 day period. If the Indemnitor is not deemed to have so acknowledged such entitlement or the Indemnitor’s
determination of whether to grant the Indemnitee’s indemnification request shall not have been made within such 30 day period, the requisite determination of entitlement to indemnification shall nonetheless be deemed to have been made and the
Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by the Indemnitee of a material fact, or an omission of a material fact necessary to make the Indemnitee’s statement not materially misleading, in connection
with the request for indemnification, or (ii) a prohibition of such indemnification under the DGCL. 
 (e) In the event that
(i) the Indemnitor determines in accordance with this Section 3 that the Indemnitee is not entitled to indemnification under this Agreement, (ii) the Indemnitor denies a request for indemnification, in whole or in part, or fails to
respond or make a determination of entitlement to indemnification within 30 days following receipt of a request for indemnification as described above, (iii) payment of indemnification is not made within such 30 day period,
(iv) advancement of expenses is not timely made in 

  
 2 

 
accordance with Section 2, or (v) the Indemnitor or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation
or other action or proceeding designed to deny, or to recover from, the Indemnitee the benefits provided or intended to be provided to the Indemnitee hereunder, the Indemnitee shall be entitled to an adjudication in any court of competent
jurisdiction of his or her entitlement to such indemnification or advancement of expenses. The Indemnitee’s expenses (including reasonable attorneys’ fees) incurred in connection with successfully establishing the Indemnitee’s right
to indemnification or advancement of expenses, in whole or in part, in any such proceeding or otherwise shall also be indemnified by the Indemnitor to the fullest extent permitted by the DGCL. 

(f) The Indemnitee shall be presumed to be entitled to indemnification and advancement of expenses under this Agreement upon submission of a
request therefor in accordance with Section 2 or this Section 3, as the case may be. The Indemnitor shall have the burden of proof in overcoming such presumption, and such presumption shall be used as a basis for a determination of
entitlement to indemnification and advancement of expenses under this Agreement unless the Indemnitor overcomes such presumption by clear and convincing evidence. 

Section 4. Insurance and Subrogation. 

(a) The rights to indemnification and advancement of expenses provided by this Agreement are in addition to any other rights to which the
Indemnitee may be entitled. The Company, the Indemnitor or one or more of their affiliates may purchase and maintain a policy or policies of insurance, providing the Indemnitee with coverage for any liability asserted against, and incurred by, the
Indemnitee or on the Indemnitee’s behalf in or arising out of the actual or purported execution or discharge of his duties or the exercise or purported exercise of his powers or otherwise in relation to or in connection with his duties, powers
or office as a director, secretary or other officer, employee or agent, in each case relating to or on behalf of the Company or its subsidiaries and affiliates. 

(b) In the event of any payment by the Indemnitor under this Agreement, the Indemnitor shall be subrogated to the extent of such payment to
all of the rights of recovery of the Indemnitee with respect to any insurance policy. The Indemnitee shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to
enable the Indemnitor to bring suit to enforce such rights in accordance with the terms of such insurance policy. The Indemnitor shall pay or reimburse all expenses actually and reasonably incurred by the Indemnitee in connection with such
subrogation. 
 (c) The Indemnitor shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder
(including, but not limited to, judgments, fines and amounts paid in settlement, and any excise taxes or penalties under the United States Employee Retirement Income Security Act of 1974, as amended, or any similar law) if and to the extent that the
Indemnitee has otherwise actually received such payment under this Agreement or any insurance policy, contract, agreement or otherwise. 

Section 5. Certain Definitions. For purposes of this Agreement, the following definitions shall apply: 

(a) The term “action, suit or proceeding” shall be broadly construed and shall include, without limitation, the
investigation, preparation, prosecution, defense, settlement, arbitration and appeal of, and the giving of testimony in, any threatened, pending or completed claim, action, suit, arbitration, alternative dispute mechanism or proceeding, whether
civil, criminal, administrative or investigative. 
 (b) The term “expenses” shall be broadly construed and shall
include, without limitation, all direct and indirect costs of any type or nature whatsoever (including, without limitation, all reasonable attorneys’ fees and related disbursements, appeal bonds, other out-of-pocket costs), actually and
reasonably incurred by the Indemnitee in connection with either the investigation, defense or appeal of an action, suit or proceeding or establishing or enforcing a right to indemnification under this Agreement or otherwise incurred in connection
with a claim that is indemnifiable hereunder. 
 (c) The term “judgments, fines and amounts paid in settlement”
shall be broadly construed and shall include, without limitation, all direct and indirect payments of any type or nature whatsoever, as well as any penalties or excise taxes assessed on a person with respect to an employee benefit plan). 

  
 3 

 Section 6. Limitation on Indemnification. Notwithstanding any other provision
herein to the contrary, the Indemnitor shall not be obligated pursuant to this Agreement: 
 (a) Claims Initiated by the
Indemnitee. To indemnify or advance expenses to the Indemnitee with respect to an action, suit or proceeding (or part thereof), however denominated, initiated by the Indemnitee, except with respect to any compulsory counterclaim, as defined
under the Federal Rules of Civil Procedure, brought by the Indemnitee or an action, suit or proceeding brought to establish or enforce a right to indemnification or advancement of expenses under this Agreement (which shall be governed by the
provisions of Section 6(b) of this Agreement), unless such action, suit or proceeding (or part thereof) was authorized or consented to by the Board of Directors of the Company. 

(b) Action for Indemnification. To indemnify the Indemnitee for any expenses incurred by the Indemnitee with respect to any
action, suit or proceeding instituted by the Indemnitee to enforce or interpret this Agreement, unless the Indemnitee is successful in such action, suit or proceeding in establishing the Indemnitee’s right, in whole or in part, to
indemnification or advancement of expenses hereunder (in which case such indemnification or advancement shall be to the fullest extent permitted by the DGCL), or unless and to the extent that the court, arbitrator or administrative body of competent
jurisdiction in such action, suit or proceeding shall determine that, despite the Indemnitee’s failure to establish their right to indemnification, the Indemnitee is entitled to indemnification for such expenses; provided, however, that nothing
in this Section 6(b) is intended to limit the Indemnitor’s obligations with respect to the advancement of expenses to the Indemnitee in connection with any such action, suit or proceeding instituted by the Indemnitee to enforce or
interpret this Agreement, as provided in Section 2. 
 (c) Fraud or wilful misconduct. To indemnify the Indemnitee on
account of conduct by the Indemnitee where such conduct has been determined by a final (not interlocutory) judgment or other adjudication of a court, arbitrator or administrative body of competent jurisdiction as to which there is no further right
or opinion of appeal or the time within which an appeal must be filed has expired without such filing to have been knowingly fraudulent or constitute wilful misconduct. 

(d) Prohibited by law. To indemnify the Indemnitee in any circumstance where such indemnification has been determined by a final
(not interlocutory) judgment or other adjudication of a court, arbitrator or administrate body of competent jurisdiction as to which there is no further right or option of appeal or the time within which an appeal must be filed has expired without
such filing to be prohibited by law. 
 Section 7. Certain Settlement Provisions. The Indemnitor shall have no obligation
to indemnify the Indemnitee under this Agreement for any amounts paid in settlement of any action, suit or proceeding without the Indemnitor’s prior written consent. The Indemnitor shall not settle any action, suit or proceeding in any manner
that would impose any fine or other obligation or restriction on the Indemnitee or require the Indemnitee to admit liability or wrongdoing without the Indemnitee’s prior written consent. Neither the Indemnitor nor the Indemnitee will
unreasonably withhold his, her, its or their consent to any proposed settlement. 
 Section 8. Savings Clause. If any
provision or provisions (or portion thereof) of this Agreement shall be invalidated on any ground by any court, arbitrator or administrative body of competent jurisdiction, then the Indemnitor shall nevertheless indemnify the Indemnitee if the
Indemnitee was or is made or is threatened to be made a party or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the Indemnitor or otherwise), whether civil, criminal, administrative
or investigative and whether formal or informal, including appeals, by reason of the fact that the Indemnitee is or was or has agreed to serve as a director, other officer, employee or agent of the Company, or while serving as a director, other
officer, employee or agent of the Company is or was serving or has agreed to serve at the request of the Company as a director, other officer, employee or agent (which, for purposes hereof, shall include a trustee, partner or manager or similar
capacity) of another corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, from and against all loss
and liability suffered and expenses (including reasonable attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by or on behalf of the Indemnitee in connection with such action, suit or proceeding, including any
appeals, to the fullest extent permitted by any applicable portion of this Agreement that shall not have been invalidated. 

  
 4 

 Section 9. Severability. If any provision of this Agreement or the application
thereof to any person or circumstance is held to be invalid, illegal or unenforceable in any applicable jurisdiction, the parties hereto agree, to the fullest extent permitted by applicable law, that (a) the validity, legality and
enforceability of the other provisions in such jurisdiction shall not be affected or impaired thereby, (b) any such invalidity, illegality or unenforceability shall not render such provision invalid, illegal, or unenforceable in any other
jurisdiction and (c) they will negotiate an amendment to such provision in such manner that it becomes valid and enforceable without affecting the original intent of the parties or the economic purpose and effect thereof. 

Section 10. Contribution. In order to provide for just and equitable contribution in circumstances in which the
indemnification provided for herein is held by a court of competent jurisdiction to be unavailable to the Indemnitee in whole or in part, it is agreed that, in such event, the Indemnitor shall, to the fullest extent permitted by law, contribute to
the payment of all of the Indemnitee’s loss and liability suffered and expenses (including reasonable attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by or on behalf of the Indemnitee in connection
with any action, suit or proceeding, including any appeals, in an amount that is just and equitable in the circumstances; provided that, without limiting the generality of the foregoing, such contribution shall not be required where such
holding by the court is due to any limitation on indemnification set forth in Section 4(c) or Section 6. 
 Section 11.
Form and Delivery of Communications. All notices, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given if (a) delivered by hand, upon receipt by the party to
whom such notice or other communication shall have been directed, (b) mailed by certified or registered mail with postage prepaid, upon receipt by the party to whom such notice or other communication shall have been directed, (c) mailed by
reputable overnight courier, one day after deposit with such courier and with written verification of receipt, or (d) sent by email or facsimile transmission, with receipt of oral confirmation that such transmission has been received. Notice to

forth in this Agreement shall not be deemed exclusive of any other rights which the Indemnitee may have under any provision of law, in any court in which a proceeding is brought, the Company’s memorandum of association or articles of
association, other agreements or otherwise, and the Indemnitee’s rights hereunder shall inure to the benefit of the heirs, executors and administrators of the Indemnitee. No amendment or alteration of the Company’s memorandum of
association or articles of association or any other agreement shall adversely affect the rights provided to the Indemnitee under this Agreement. 

Section 13. No Construction as Employment Agreement. Nothing contained herein shall be construed as giving the Indemnitee
any right to be retained as a director, secretary or other officer, employee or agent of the Company or in the employ of the Company. For the avoidance of doubt, the indemnification and advancement of expenses provided under this Agreement shall
continue as to the Indemnitee even though he or she may have ceased to be a director, secretary, other officer, employee or agent of the Company. 

Section 14. Interpretation of Agreement. It is understood that the parties hereto intend this Agreement to be interpreted
and enforced so as to provide indemnification to the Indemnitee to the fullest extent now or hereafter permitted by the DGCL. 

Section 15. Entire Agreement. This Agreement and the documents expressly referred to herein constitute the entire agreement
between the parties hereto with respect to the matters covered hereby, and any other prior or contemporaneous oral or written understandings or agreements with respect to the matters covered hereby are expressly superseded by this Agreement. For the
avoidance of doubt, the parties confirm that the foregoing does not limit any of the Indemnitee’s rights under the Company’s memorandum of association or articles of association. 

  
 5 

 Section 16. Modification and Waiver. No supplement, modification, waiver or
amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto; provided that either party may modify the notice information related to such party provided in Section 11 by written notice to the
other party hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. For the avoidance of
doubt, this Agreement may not be terminated by the Indemnitor without the Indemnitee’s prior written consent. 
 Section 17.
Successor and Assigns. All of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable by the parties hereto and their respective successors, assigns, heirs, executors,
administrators and legal representatives. The Company shall require and cause any direct or indirect successor to all or substantially all of the business or assets of the Indemnitor (whether by purchase, merger, consolidation or otherwise), by
written agreement in form and substance reasonably satisfactory to the Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Indemnitor would be required to perform if no such
succession had taken place. 
 Section 18. Service of Process and Venue. The Company and the Indemnitor hereby
irrevocably and unconditionally (a) agree that any action or proceeding arising out of or in connection with this Agreement may brought in the Chancery Court of the State of Delaware (the “Delaware Court”),

service of process in the State of Delaware, irrevocably Corporate Creations Network Inc., 3411 Silverside Road #104 Rodney Building, Wilmington, DE 19810, as its agent in the State of Delaware for acceptance of legal process in connection with any
such action or proceeding against such party with the same legal force and validity as if served upon the Company personally within the State of Delaware, (d) waive any objection to the laying of venue of any such action or proceeding in the
Delaware Court and (e) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper or inconvenient forum. 

Section 19. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of
Delaware. If a court of competent jurisdiction shall make a final determination that the provisions of the law of any jurisdiction other than the State of Delaware govern indemnification by the Indemnitor of the Indemnitee, then the indemnification
provided under this Agreement shall in all instances be enforceable to the fullest extent permitted under such law, notwithstanding any provision of this Agreement to the contrary. 

Section 20. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be
an original and all of which together shall be deemed to be one and the same instrument, notwithstanding that both parties are not signatories to the original or same counterpart. 

Section 21. Headings and Section References. The section and subsection headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. Section references are to this Agreement unless otherwise specified.

Section 4.           Representations and Warranties
of Investors.

 

(a)           Montsant is a limited liability company
duly organized, validly existing and in good standing under the laws of Delaware. Platinum is a limited partnership duly organized,
validly existing and in good standing under the laws of Delaware.

 

(b)           The Investors have the requisite power
and authority to enter into and perform this Agreement and to acquire the Warrants being issued to them hereunder. The execution,
delivery and performance of this Agreement by the Investors and the consummation by it of the transactions contemplated hereby
(i) have been duly authorized by all necessary limited liability company action, and (ii) do not contravene the terms of the organizational
or governing documents of the Investors. No further consent or authorization of the Investors, their board of directors or other
governing body, or of their members or partners, as applicable, is required for the execution, delivery or performance of this
Agreement by the Investors. When executed and delivered by the Investors, this Agreement shall constitute the valid and binding
obligation of the Investors enforceable against the Investors in accordance with its terms, except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation, conservatorship, receivership or similar
laws relating to, or affecting generally the enforcement of, creditor’s rights and remedies or by other equitable principles
of general application.

 

(c)           Each Investor owns and holds, beneficially
and of record, the entire right, title, and interest in and to the Original Securities set forth opposite its name on Exhibit
A hereto, free and clear of any claim, restriction or Lien other than restrictions on transfer under the Securities Act and
applicable state securities laws.

 

(d)           Each Investor is acquiring the Warrants
for its own account and not with a view to or for sale in connection with a distribution thereof. The Investors do not have a present
intention to sell any of the Warrants, nor a present arrangement (whether or not legally binding) or intention to effect any distribution
of any of the Securities to or through any Person or entity; provided, however, that by making the representations
herein, the Investors do not agree to hold the Warrants (or securities issued upon exercise of the Warrants) for any minimum or
other specific term and reserves the right to dispose of such securities at any time in accordance with federal and state securities
laws applicable to such disposition and the terms of the Warrants. Each Investor acknowledges and agrees that the Warrants shall

THIS WARRANT AND THE SHARES OF COMMON
STOCK ISSUABLE UPON EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”) OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER THE

COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE SECURITIES LAWS
IS NOT REQUIRED.

 

    	 	5	 

     

    

 

(e)           Each Investor is an “accredited
investor” as defined in Rule 501(a) under the Securities Act. Each Investor has such experience in business and financial
matters that it is capable of evaluating the merits and risks of an investment in the Series B Shares. The Investors are not required
to be registered as a broker-dealer under Section 15 of the Exchange Act and no Investor is a broker-dealer. The Investors acknowledges
that an investment in the Securities is speculative and involves a high degree of risk.

 

(f)           The Investors understand that the Warrants
and the Common Stock receivable upon exercise of the same have not been registered under the Securities Act and must be held indefinitely
unless registered under the Securities Act or an exemption from registration is available. The Investors acknowledge that they
are familiar with Rule 144, and that the Investors have been advised that Rule 144 permits resales of unregistered securities only
under certain circumstances. The Investors understand that to the extent that Rule 144 is not available, the Investors will be
unable to sell the Warrants or any shares of Common Stock received upon exercise of the same without either registration under
the Securities Act or the existence of another exemption from such registration requirement.

 

(g)           Each Investor has independently evaluated
the merits of its decision to exchange the Series B Stock for the Warrants pursuant to the Transaction Documents. The Investors
have not relied on the business or legal advice of the Company or any of its agents, counsel or Affiliates in making its investment
decision hereunder, and confirms that none of such Persons has made any representations or warranties to the Investors in connection
with the transactions contemplated by the Transaction Documents other than as contained therein

 

(h)           The Investors understand that the Warrants
are being issued in reliance on an exemption from the registration requirements of federal and state securities laws and the Company
is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of the
Investors set forth herein in order to determine the applicability of such exemptions. The Investors understand that no Governmental
Authority has passed upon or made any recommendation or endorsement of the Warrants or Common Stock.

 

(i)           The Investors have not employed any
broker or finder or incurred any liability for any brokerage or investment banking fees, commissions, finders’ structuring
fees, financial advisory fees or other similar fees in connection with the transactions contemplated by this Agreement.

 

(j)           Other than the other Investor and the
Reporting Persons named in the Schedule 13G filed on or about February 20, 2015 by Platinum and the other Reporting Persons named
therein, no Investor has agreed to act with any other Person for the purpose of acquiring, holding, voting or disposing of the
Warrants acquired hereunder or the Common Stock receivable upon exercise of the same for purposes of Section 13(d) of the Exchange
Act, and each Investor is acting independently with respect to its investment in the Securities.

Section 7.           Covenants of the Company.
The Company covenants and agrees with the Investors as follows:

 

(a)           The Company shall not enter into any
agreement in which the terms of such agreement would materially restrict or impair the right or ability to perform of the Company
or any Subsidiary under any Transaction Document.

 

(b)           So long as the Investors beneficially
owns any of the Warrants, the Company shall timely file all reports required to be filed with the Commission pursuant to the Exchange
Act, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange
Act or the rules and regulations thereunder would permit such termination.

 

(c)           The Company will provide, at the Company’s
expense, such legal opinions in the future as are reasonably necessary for the issuance and resale of the Common Stock issuable
upon exercise of the Warrants pursuant to an effective registration statement, Rule 144 under the Securities Act or an exemption
from registration, to the extent applicable. In the event that Common Stock is sold in a manner that complies with an exemption

removal of the legend (indefinitely, if under Rule 144, such shares of Common Stock may be sold without regards to volume limitations
or the availability of current public information concerning the Company, or to otherwise permit sale of the shares if pursuant
to the other provisions of Rule 144).

 

(d)           The Company covenants and agrees that
neither it nor any other person acting on its behalf will provide the Investors or their agents or counsel with any information
that the Company believes constitutes material non-public information, unless prior thereto the Investors shall have executed a
written agreement regarding the confidentiality and use of such information. The Company understands and confirms that the Investors
shall be relying on the foregoing representations in effecting transactions in securities of the Company. In the event of a breach
of the foregoing covenant by the Company, or any of its Subsidiaries, or any of its or their respective officers, directors, employees
and agents, in addition to any other remedy provided herein or in the Transaction Documents, the Company shall publicly disclose
any material, non-public information in a Form 8-K within five (5) Business Days of the date that it discloses such information
to an Investor. In the event that the Company discloses any material, non-public information to any Investor and fails to publicly
file a Form 8-K in accordance with the above, such Investor shall have the right to make a public disclosure, in the form of a
press release, public advertisement or otherwise, of such material, nonpublic information without the prior approval by the Company,
its Subsidiaries, or any of its or their respective officers, directors, employees or agents. The Investors shall have no liability
to the Company, its Subsidiaries, or any of its or their respective officers, directors, employees, stockholders or agents, for

(e)           During the term of the Warrants, so
long as at least 25% of the Warrants (on an aggregate basis) remains unexercised, the Company shall not, without the written consent
of the Investors: (i) repurchase, redeem or pay dividends on (whether in cash, in kind, or otherwise), shares of the Common Stock;
(ii) effect any distribution with respect to the Common Stock, or (iii) issue any Common Stock or Common Stock equivalent for a
per Common Stock share effective price less than $1.35, other than (1) issuances of securities upon the exercise or exchange of

by the Company as consideration for the issue or sale of such Common Stock equivalents, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exercise thereof, by (Y) the total maximum number of shares

Section 8.           Miscellaneous.

 

(a)           Each party shall pay the fees and expenses

negotiation, preparation, execution, delivery and performance of this Agreement.

and delivering the same to the requesting party or parties. This Agreement may be executed in any number of counterparts and by
the parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which

(c)           This Agreement and the Warrants contain
the entire understanding and agreement of the parties with respect to the matters covered hereby and, except as specifically set
forth herein or therein, neither the Company nor the Investors make any representation, warranty, covenant or undertaking with
